Estimating postmortem interval for human cadavers in a sub‐tropical climate using UV‐Vis‐near‐infrared Spectroscopy

Estimating postmortem interval (PMI) of surface found skeletal remains is challenging. This novel study used UV‐Vis‐NIR spectroscopy to scan soil collected from cadaver decomposition islands (CDIs) ranging from 15‐ to 963‐d postmortem and control soils. A decomposition product spectra model (DPS model) was constructed by deducting the control soil spectra from the CDI soil spectra for the estimation of postmortem indices: PMI (d), ADD₄, ADD₁₀, and ADD₂₀. The DPS model (n = 55) was calibrated and subjected to a full cross‐validation. Calibration R² and RPD for the DPS model ranged from 0.97 to 0.99 and from 6.1 to 9.9, respectively, for the four postmortem interval indices. Validation R² and RPD for the DPS model ranged from 0.73 to 0.80 and from 1.9 to 2.2, respectively. The DPS model estimated postmortem intervals for three test CDIs in a clay soil under perennial grassland (test set 1; n = 3) and six CDIs in a sandy soil under a loblolly pine forest (test set 2; n = 6). Test set 1 had PMI prediction ranges from ?69 to ?117 days, ?796 to +832 ADD₄, +552 to +2672 ADD₁₀, and ?478 to ?20 ADD₂₀ of observed PMI. Test set 2 PMI prediction ranged from ?198 to ?65 days, ?9923 to +2629 ADD₄, ?6724 to +1321 ADD₁₀, and ?2850 to +540 ADD₂₀ of observed PMI. Test set 2 had poor predictions for two CDIs, for all measures of postmortem indices resulting in discussion of sampling depth, effect of body mass index (BMI), and scavenging.     

Mock jurors' perceptions of identifications made by intoxicated eyewitnesses

Abstract

Psychology research has generally neglected intoxicated eyewitnesses. The current study addressed this need by exploring mock jurors' perceptions of intoxicated witnesses. Undergraduate participants read summarized sexual or aggravated battery cases in which either the victim or a bystander identified the defendant under varying intoxication levels. They answered questions about the case and provided verdicts. Participants were sensitive to the effect that intoxication may have on witnesses' cognitive ability, but not to varying degrees of intoxication. Neither the role of the eyewitness nor the type of crime committed had an effect on perceptions of witness impairment. Participants' perceptions of witness impairment informed identification credibility ratings, and credibility assessments affected verdicts. Impairment and credibility ratings fully mediated intoxication's effect on verdicts. Unlike much prior research, our results suggest that mock jurors can consider potentially important witness information when rendering verdicts.     

Is sexually abusive behaviour in personality disordered inpatients analogous to sexual offences committed prior to hospitalization?

Abstract

Sexually abusive behaviour by personality disordered patients presents a serious threat to the integrity of staff–patient relationships and the safety of other residents. The occurrence of such behaviour is also problematic for the offending patient, as it may impact on perceived treatment needs and their access to the community. This paper reports on a study of sexually abusive behaviour in a high security psychiatric hospital. It also examines the relationship between these behaviours and patients’ history of sexual offending. The results showed a high frequency of low-severity sexually abusive behaviour and no significant associations between sexually abusive behaviour during hospitalization and sexual offence history. These findings imply that low-severity sexually abusive behaviour within secure settings may be determined, partly, by environmental conditions. This sexual abuse may also be functionally dissimilar to severe sexual abuse perpetrated in the community. The meaning and determinants of sexual abuse within secure settings must be scrutinized carefully and comprehensively before they are considered analogous to previous sexual offences.     

The Effects of Tenure on Staff Apathy and Treatment Orientation: A Comparison of Respondent Characteristics and Environmental Factors

Because inmate rehabilitation efforts are influenced by prison staff, Pennsylvania’s Department of Corrections recently began collecting survey data from corrections staff about their attitudes and beliefs for treatment programming. The present analysis focused on staff tenure, or length of time employed in a corrections field, and its effects on support for inmate rehabilitation. Overall, findings from bivariate analyses clearly showed that staff with 16 years or more of service expressed less apathy and demonstrated a treatment orientation perspective toward inmate rehabilitation. Findings from multivariate analyses showed that respondent characteristics including tenure and job category were stronger predictors of staff apathy and a treatment orientation perspective than were environmental factors associated with the prisons. Policy implications will be discussed.

Civil Legal Aid and Domestic Violence: a Review of the Literature and Promising Directions

This note summarizes extant research on civil legal aid, which includes provision of legal services for indigent and low-income individuals, and its applications for DV and IPV victims, and concludes with suggestions for improving service delivery and research in the field. Results of searches of online databases for peer-reviewed and non-peer reviewed articles, reports, analyses, and evaluations of civil legal aid in the United States were analyzed and critically assessed. Civil legal aid is a promising but underfunded and underexplored avenue for responding to and reducing domestic violence (DV), intimate partner violence (IPV), and their devastating effects. Providing civil counsel in divorce, custody, and protective order proceedings can significantly improve outcomes for DV and IPV victims and their children as well as serve as a cost-effective strategy for reducing violence and generating positive social returns.
