Workplace Sexual Harassment in Policing: Perceived Psychological Injuries by Source and Severity

Relatively little is known about employee perceptions of workplace psychological injuries following sexual and nonsexual harassment. In quasi-military occupational organizations, such as policing, the rate of sexual harassment to workplace injuries from other sources is comparatively high. In an exploratory 5?×?2 between-subjects factorial experimental projection study, 220 New South Wales Police Force officers responded to one of ten experimental vignettes in which sources of psychological injury and the gender of the injured worker were systematically varied. Results revealed an unexpected effect of experience. Employees aged 30 years and older were significantly more likely to anticipate psychological consequences and clinically diagnosable symptoms than their younger counterparts. As hypothesized, a main effect of injury source, but not gender of the target, emerged for the severity of psychological consequences: a physical injury was perceived to produce significantly more severe psychological injuries than sexual harassment in the form of coercion and unwanted sexual attention. Contrary to the hypothesis, participants rated gender-based hostility higher than other types of sexual harassment as a source of severe psychological harm. Participants believed that gender-based hostility requires more professional intervention and predicted more negative workplace consequences than other psychological injuries caused by other workplace events. As hypothesized, women employees were generally viewed as significantly more vulnerable to negative workplace outcomes than men. The police officers who participated in this study considered women as more likely to experience workplace problems following sexual coercion than other types of workplace injury. Physical injuries, gender-based hostility, and sexual coercion were distinguished from nonsexual harassment and unwanted sexual attention as significantly more likely to produce clinically diagnosable injuries, irrespective of target gender. Implications of these findings for research, practice, and legal policy are discussed.     

Evaluation of the (hu)MANid program for sex and ancestry estimation in a diverse,contemporary CT scan-based sample

Human remains from forensic and bioarcheological contexts are often fragmentary, requiring methods for estimating a forensic profile that are based upon limited skeletal features. In 2017, Berg and Keryhercz created an online application, (hu)MANid, that provides sex and ancestry estimation from mandibular morphoscopic traits and linear measurements. In this study, we examine the utility of the (hu)MANid application in a diverse, urban US adult sample (aged 20–45; n = 143) derived from computed tomography (CT) scans. We secondarily conduct a preliminary analysis of the program's utility in a sample of adolescents (aged 15–17; n = 40). Six morphoscopic, and eleven morphometric traits were recorded as directed by the literature associated with the (hu)MANid program. Percent correct classification and posterior predictive values were calculated for the sex and ancestry estimations output by the program; chi-squared tests were employed to compare self-reported and predicted ancestry. In the adult sample, sex was accurately predicted for 75.52% of the sample. Ancestry prediction, however, was less favorable ranging from 19.3% to 50% correct. For the adolescent sample, correct sex estimation (45%) did not surpass what could occur by chance alone, though ancestry prediction fared better than in the larger adult sample (percent correct prediction overall average: 47.5%, range 35.71%–71.43%). The (hu)MANid application shows utility for use with CT scan-derived adult samples for sex estimation, but caution is warranted for ancestry estimation and use with samples that may not have reached full adult maturity.     

Evaluating expertise in forensic anthropology

The medicolegal system relies on the ability of experts and non-experts alike to make judgments about expertise and use those judgments to reach consequential decisions. Given the lack of standard criteria, mandatory certification, or licensure for establishing expertise required to practice forensic anthropology and testify as an expert witness, we sought to understand how individuals assess and identify expertise in forensic anthropology by using a social science tool called the Imitation Game. This tool assesses immersion in a specific area of study via discourse, with the premise that some individuals lacking expertise themselves imitate or attempt to pass as experts. For this project we recruited volunteers with varying expertise in forensic anthropology to participate in interviews which asked questions about the practice and structure of the discipline. Those interviews were transcribed, anonymized, and evaluated by other recruited individuals with varying expertise in forensic anthropology. Results found that judges who were experts in forensic anthropology performed better than non-expert judges in determining who was not an expert in forensic anthropology based on their anonymized responses; however, nearly half of the non-experts were still able to pass as experts in forensic anthropology. The difficulties in assessing expertise based on discourse interactions demonstrates the value and need for well-defined credentials and mandatory certification to practice forensic anthropology. This study demonstrates that accurately identifying expertise in forensic anthropology may be challenging for both experts and non-experts, especially when relying solely on interactional expertise rather than formal assessments of competency which directly elucidate contributory expertise.     

A comparison of plastic cable ties based on physical,chemical and stable isotopic measurements

Plastic cable ties can be utilised in a range of serious criminal activities and a comparison of cable ties, or fragments, may form part of the physical evidence presented to a Court of law. This research assessed the potential value of evidence based on the analysis of plastic cable ties. Twenty packets of black coloured plastic cable ties (nominally 200 mm × 4.8 mm) were purchased in pack sizes ranging from 25 to 100 individual cable ties (Brisbane, Australia, March 2015). Representative samples from each packet were visually examined, compared and tested to determine their physical dimensions, chemical compositions and stable isotopic compositions (δ²H, δ¹³C and δ¹⁵N).All of the individual cable ties from a given packet were found to be indistinguishable with respect to appearance, physical, chemical and isotopic measurements (within-batch variability). Individual cable ties were also found to be isotopically homogeneous with respect to hydrogen, carbon and nitrogen. All of the cable ties analysed were found to have very similar chemical compositions and to be manufactured predominantly from nylon 6,6. The elemental compositions of composite samples, prepared from each packet, were found to be highly variable and, as such, were of very limited value.Cable ties from ten of the twenty packets were uniquely characterised by physical appearance (between-batch variability). Physical measurements such as the width, thickness and tooth-count of the grip section did not provide additional discrimination. Cable ties from nineteen of the twenty packets were uniquely characterised by isotopic composition, based on δ²H and δ¹⁵N measurements. Samples from two packets of Crescent brand cable ties were found to be indistinguishable with respect to all of the tests applied in this study. These two packets were inadvertently purchased from the same retailer and had the same barcode and batch number. It was considered a reasonable assumption that these two packets originated from the same manufacturing batch.The authors reason that a likelihood ratio (that might be presented to a Court of law) can be derived from this type of discrete data based on a calculation of the possible combinations of distinguishable objects (unordered sampling with replacement) in a convenience sample collected from the background population. In this example, a database of 19 distinguishable objects can yield a likelihood ratio as high as 210, with a verbal equivalent of “moderately strong support” for a proposition that two cable ties have the same isotopic composition because they originate from the same batch rather than by random chance.     

The Offset Rule: Some Multinational Evidence

The offset rule is a method to simplify the calculation of lump sum damage awards to compensate victims for an expected lost future flow of income. If the expected nominal rate of interest is roughly equal to the expected rate of growth in nominal wages (assuming the loss is due to lost labour income), then the present discounted value of the loss is shown to be easily computed as just the amount of the loss in the first year multiplied by the number of years over which the loss is expected to occur. We test the assumptions of the offset rule for eleven different countries. For each country, we cannot reject the hypothesis that the assumptions of the offset rule are satisfied. The relevant implication of this work is that the offset rule can provide a starting point for the assessment of damages. While there are undoubtedly good arguments for personalizing awards, there is no longer any good reason to debate the size of the real rate of interest, the expected rate of inflation, or average changes in labour productivity. These variables cancel each other out in the offset rule.     

Results of four inter-laboratory comparisons provided by the Forensic Isotope Ratio Mass Spectrometry (FIRMS) network

Between 2004 and 2008 the Forensic Isotope Ratio Mass Spectrometry (FIRMS) network organised four Inter-Laboratory Camparison excercises with the aim of harmonising and validating isotopic measurements to be used for forensic applications.The samples distributed comprised materials of potential forensic interest such as packaging and pharmaceuticals to be analysed for δ²H, δ¹³C, δ¹⁵N and δ¹⁸O composition. As many as 30 international laboratories participated in these comparisons. Results have shown overall improvements for both within- and inter-laboratory reproducibility with respect to δ¹³C and δ¹⁵N measurements.Only a small number of laboratories returned results for δ²H and δ¹⁸O analysis and these results highlighted a need for improvement in the reproducibility of these measurements and a need to address the exchange of hydrogen between samples and ambient moisture. Results also highlighted the importance of sample preparation procedures and the need to standardise both these procedures and calibration against Standard Reference Materials. Future Inter-Laboratory Comparison exercises will assess the suitability of laboratories to submit data to national and international databases similar to those currently operated for fingerprints, DNA etc.     

Preliminary trials of low volume AmpFlSTR Profiler Plus amplification using AmpliGrid (AG480F) slides

Low volume PCR using the AmpliGrid (480F) slide system can potentially enhance the generation of more complete profiles from trace samples, in addition to providing a more cost-effective alternative for typing standard samples. Based on our preliminary results, implementation will require a reasonable investment in optimisation and validation for the intended purpose.     

Vital animal predation of the genital region caused by a mongrel dog

A 79-year-old man, who was in a helpless situation due to cardiac decompensation, suffered dog bite injuries on the left thigh and in the genital region while still alive. Two extensive soft-tissue defects with contused and bruised wound edges were surrounded by multiple slit-like skin lesions. The outer genitals were almost completely missing. Because of surgical emergency treatment, molecular biological investigations were no longer possible. Therefore, the cause of the bite injuries had to be determined solely on the basis of the documented morphology of the wounds.     

Education and Career Satisfaction: Examining the Specifics of the Relationship Among Criminal Justice Graduates

Several studies have considered the source of job satisfaction across different types of criminal justice professionals. This article identifies factors related to job satisfaction among graduates from a criminal justice program. The authors use a sample of 236 criminal justice graduates to explore the role of education in reports of career satisfaction. Findings indicate that graduates who felt they received adequate training in the social sciences were more likely to report satisfaction with their careers. Perceptions of preparation for careers/graduate study also were related to job satisfaction. Perceptions of course availability and independent studies/research opportunities also played a role. Implications are provided.
