A Comparison of Four Presumptive Tests for the Detection of Blood on Dark Materials

Detection of blood on dark materials is difficult for crime scene examiners so presumptive tests are used to assist. This study compared the ability of luminol, leuko crystal violet, tetramethylbenzidine, and Combur Test®E to detect whole, diluted blood (1:100) and a key‐shaped blood transfer stain (1:10), on dark cotton sheeting, tea towel, socks, synthetic carpet, and car mats. Powdered bleach was used to evaluate specificity of the blood detection tests. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and overall misclassification rate (OMR) assessed the quality of the blood tests. Luminol was the preferred test for diluted blood having the highest sensitivity (79%–96%), NPV (66%–93%), and the lowest OMR (3%–15%). Luminol was also found to be most efficient with a testing time on 25 items of 2 h 50 min compared with up to 8 h. Overall, luminol was the most effective method, also providing information on bloodstain patterns.     

For the Want of Certainty: Vnuk,Juliana and Andrade and the Obligation to Insure

In 2014, the Court of Justice of the European Union in Damijan Vnuk v Zavarovalnica Triglav extended the requirement for the owner of a motor vehicle to possess insurance cover where the vehicle is used on a road or other public place to vehicles on private land. Beyond disquiet as to this extension, there remains uncertainty at statutory and jurisprudential levels. According to Fundo de Garantia Automóvel v Juliana, immobilised vehicles stored on private land but which are capable of being driven are subject to compulsory motor vehicle insurance whereas in Andrade v Crédito Agrícola Seguros, insurance is required only where the vehicle is used as a means of transport. Andrade appears overly restrictive and may operate to defeat the protections of the Motor Vehicle Insurance Directives. Clarification is needed, through a seventh MVID or direction from the CJEU, as to the authority of Andrade and the circumstances in which motor vehicles must be insured.     

Modern Families,Modern Family Justice: Supporting Family Relationships in Fast‐Changing Socio‐Political‐Economic Climates (Summary of the Report of the Consultation at St George's House,Windsor, February 12–13, 2018)

This summary relates to the consultation held at St George's House, in Windsor, England, on February 2018. The attendees came from across Europe and from the United States, and they discussed a range of initiatives designed to address the challenges in modern family justice and the changes in the social, political, and economic environments that are impacting family life across the globe. Although the challenges are very similar, the approach to resolving them varies from jurisdiction to jurisdiction. The attendees concluded that there is much we can learn from each other, and that greater cooperation between family justice professionals across geographic boundaries would be highly beneficial.     

Perceived and Observed Maternal Relationship Quality Predict Sexual Debut by Age 15

Early sexual behaviors during adolescence have the potential to lead to unhealthy outcomes. This study explored the association between specific dimensions of maternal relationship quality and adolescent sexual debut by age 15. We hypothesized that adolescents who have poor maternal relationships are at greater risk of early sexual debut than those who have a more supportive relationship. These hypotheses were examined using both adolescents’ perception of their maternal relationship quality and observed relationship quality. A sample of 268 adolescents (142 girls; 90% European American) were followed longitudinally from age 13 to age 15. The results indicate that adolescents with sexual debut by age 15 report significantly worse relationships with their mothers compared with other adolescents. Furthermore, behavioral observations of lower maternal support and higher observed displays of externalizing affect towards the mother also were related to early sexual debut. The significance of maternal relationship quality remained after controlling for family structure, race, and socioeconomic status. These findings suggest that mothers have a significant role in the timing of their adolescents’ sexual debut.     

Research note: The founders and survivors project

This paper describes the multidisciplinary project Founders and Survivors: Australian Life Courses in Historical Context. Individual life courses, families and generations through the nineteenth and twentieth centuries are being reconstituted from a wide range of data including convict records; birth, death and marriage registrations; and World War I service records. The project will result in a longitudinal study of Australian settlement, the long-run effects of forced labour and emigration on health and survival, family formation, intergenerational morbidity and mortality, and social and geographic mobility.
