Hanging deaths with bound hands: what is the manner?

In Franklin County, Ohio, 3 cases of hangings with bound hands were reported in a 4-month period in 2005. All of the victims were men. In 2 of the 3 cases, the hands were bound behind the back. One victim bound his hands in front of his body. In each case, the police ruled the deaths "suspicious" due to the fact that the victims' hands were bound. Complete investigation is required. Only after a thorough scene investigation, medicolegal autopsy, and knowledge of recent circumstances of the decedent's life can a determination of manner be made.     

A Comparison of Thresholding Methods for Forensic Reconstruction Studies Using Fluorescent Powder Proxies for Trace Materials

Image segmentation is a fundamental precursor to quantitative image analysis. At present, no standardised methodology exists for segmenting images of fluorescent proxies for trace evidence. Experiments evaluated (i) whether manual segmentation is reproducible within and between examiners (with three participants repeatedly tracing three images) (ii) whether manually defining a threshold level offers accurate and reproducible results (with 20 examiners segmenting 10 images), and (iii) whether a global thresholding algorithm might perform with similar accuracy, while offering improved reproducibility and efficiency (16 algorithms tested). Statistically significant differences were seen between examiners’ traced outputs. Manually thresholding produced good accuracy on average (within ±1% of the expected values), but poor reproducibility (with multiple outliers). Three algorithms (Yen, MaxEntropy, and RenyiEntropy) offered similar accuracy, with improved reproducibility and efficiency. Together, these findings suggest that appropriate algorithms could perform thresholding tasks as part of a robust workflow for reconstruction studies employing fluorescent proxies for trace evidence.     

Evaluation of a Teen Dating Violence Prevention Intervention among Urban Middle-School Youth Using Youth Participatory Action Research: Lessons Learned from <Emphasis Type="Italic">Start Strong Boston</Emphasis>

Almost half of adolescents aged 11 to 14 have dated and between 10 and 30% report experiencing Teen Dating Violence (TDV). However, there are no evidence-based TDV prevention interventions designed for afterschool, community-based settings with middle-school youth, in high-risk neighborhoods. Start Strong Boston (SSB) is a model that fills all three gaps, founded on partnerships between the Boston Public Health Commission, community afterschool sites, academic experts and evaluators, and youth. Here, we describe the SSB program and discuss how this collaboration built upon successes of this peer-engaged intervention, by developing and implementing a youth participatory action research (YPAR) evaluation study of SSB. Use of the YPAR framework tested the feasibility of employing Peer Researchers in an interdisciplinary evaluation team. We describe how through participation in evaluation research, Peer Researchers improve professional and leadership skills while informing measurement and conceptualization of a program affecting their own neighborhoods. Lessons learned are presented.     

Policy on innovation in Australia: Divergence in definitions,problems, and solutions

Innovation has joined the mainstream in many nations as governments search for new ways to tackle challenging societal and economic problems. But Australia is seen to be lagging on innovation policy. Is this related to how governments define innovation? What do they regard as the problem they are addressing? What proposed solutions follow from this? This paper examines how Australian governments have defined innovation over four decades, signalling their policy intentions about how to make the nation more innovative. Definitions of innovation are analysed using 79 Australian (national level) policy documents published from 1976 to 2019. Close reading of these documents suggests two main definitions: innovation as technology, and innovation as culture. Topic modelling uncovers more differentiated themes, shows how definitions change over time, and demonstrates an association between definitions and political parties in government. The divergent approaches suggest a lack of coherence and continuity to policy on innovation in Australia.

Points for practitioners

• Innovation has expanded and broadened in its definition and governments and policymakers have paid increasing attention to it.
• In Australia, there are two main definitions of innovation used in policy—one related to technology and one related to culture.
• The technology view of innovation can be further divided into a focus on businesses or a focus on research and development (R&D).
• Different innovation definitions, problems, and solutions dominate at different times, with Coalition governments tending to favour business and technology over culture, and Labor governments doing the opposite.
• There are divergent approaches to policy on innovation in Australia which suggest a lack of coherence and consistency in policy over the long term.
