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.     

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.     

Collaborative Leadership in the Arts as a Unique Form of Dual Leadership

This article examines dual leadership in Australian performing arts companies, reflected in the respective roles of artistic directors and general managers. Our findings challenge assumptions underpinning much of the literature on dual leadership; in particular, the assumption that conflict is inevitable between the two leaders. In our research, we identified dual leadership relationships that might more accurately be described as instances of collaborative leadership. We suggest that one explanation for this presence of collaborative leadership may be that the study found similarities in both leaders’ passion for the arts, often reflected in a shared background in an arts practice.
