DNA as Evidence: Viewing Science through the Prism of the Law

In this article, we analyze a problem related to DNA evidence that is likely to be of great and increasing significance in the near future. This is the problem of whether, and how, to present evidence that the suspect has been identified through a DNA database search. In our view, the two well-known reports on DNA evidence issued by the National Research Council (NRC) have been badly mistaken in their analysis of this problem. The mistakes are significant because the reports have carried great authority with American courts; moreover, the DNA Advisory Board of the FBI has endorsed the second report on this issue. We will also offer some reflections on the habits of mind, of both lawyers and statisticians, that may have led to this result

DNA Database Searches and the Legal Consumption of Scientific Evidence

DNA evidence has transformed the proof of identity in criminal litigation, but it has also introduced daunting problems of statistical analysis into the process. In this Article, we analyze a problem related to DNA evidence that is likely to be of great and increasing significance in the near future. This is the problem of whether, and how, to present evidence that the suspect has been identified through a DNA database search. In our view, the two well-known reports on DNA evidence issued by the National Research Council ( NRC ), each of which has carried great authority with the American courts on various issues, have been badly mistaken in their analysis of this problem. Similar errors affect the analyses of scholars who have supported the NRC reports. We will also offer some reflections on the habits of mind, of both lawyers and statisticians, that may have led to this result. Finally, we will suggest an approach that legal decision-makers might take in general with respect to scientific and statistically-based evidence to avoid this kind of difficulty. This approach is significantly different from that which pervades the Supreme Court\u27s decisions in Daubert v. Merrell Dow Pharmaceuticals, Inc. and its recent sequel, General Electric Co. v. Joiner, as well as their precursor, Frye v. United States. And the suggested approach sheds a helpful light on a case now pending before the Court, Carmichael v. Samyang Tire, Inc

Violence brief interventions: a rapid review

Provision of a Violence Brief Intervention (VBI) to young men undergoing treatment for a violent injury may represent a teachable moment for the prevention of future interpersonal violence in Scotland. Prior to intervention design, a rapid review of the research literature was necessary to examine existing programmes. After title and abstract screening, eight distinct VBIs were identified from full texts. Whilst none of the programmes were a perfect match for our intervention goals, they did demonstrate the potential effectiveness of brief interventions for violence prevention at both cognitive and behavioural levels. Key themes of successful interventions included brief motivational interviewing as an effective method of engaging with at-risk participants and encouraging change, the utility of social norms approaches for correcting peer norm misperceptions, the usefulness of working with victims of violence in medical settings (particularly oral and maxillofacial surgeries), the importance of addressing the role of alcohol after violent injury, the advantages of a computer-therapist hybrid model of delivery, and the need for adequate follow-up evaluation as part of a randomised control trial. This information has been used to design a VBI which is currently under evaluation

Impact of more intensive grazing on nitrogen and phosphorus in shallow aquifers of the Southern Perth Basin

This study reports on the nutrient content, pH and salinity of groundwater samples collected from the watertable and within the Superficial and the upper Leederville Aquifers from the Southern Perth Basin, south of Pinjarra, Western Australia. Sampling was undertaken to determine the impact of intensification of broadscale grazing on groundwater nutrients in the area

Effectiveness of universal school-based programs for prevention of violence in adolescents

Objective: Violence is a leading cause of morbidity and mortality amongst young people. Primary preventive programs aimed at reducing the involvement of young people in violence are often implemented in a school setting. This systematic review evaluated the effectiveness of universal school-based programs aimed at the primary prevention of violence in 11-18 year olds. Method: A pre-defined search strategy was used to search various sources (i.e. databases, gray literature, previous reviews, and reference lists of included studies) for randomised design trials and quasi-experimental design trials published between 2002 and March 2014. After screening 8051 abstracts, 21 studies were identified that satisfied the inclusion/exclusion criteria. These studies evaluated 16 different programs based mainly in the US. Results: Due to the heterogeneity meta-analysis was not possible; thus a narrative synthesis was reported. The most effective interventions utilised social development and social norms components. Attitudes towards violence was the most frequently measured outcome with six studies reporting a beneficial effect and two reporting no effect; three of the six studies examining violent behaviour demonstrated a small beneficial effect; and four of the seven studies examining physical aggression demonstrated a small beneficial effect. Conclusions: In general, this review found limited evidence of the effectiveness of universal school-based programs in the primary prevention of violence in 11-18 year olds; however, those that combined social development and social norms approaches appeared to be the most effective. Additional qualitative research/process evaluation is required to establish the processes that underpin the success/failure of such programs in order to inform their refinement, and the future development of effective programs.PostprintPeer reviewe

Transforming health care: the policy and politics of service reconfiguration in the UK’s four health systems

Public involvement in service change has been identified as a key facilitator of health care transformation (Foley et al., 2017) but little is known about how health policy influences whether and how organisations involve the public in change processes. This qualitative study compares policy and practice for involving the public in major service changes across the UK's four health systems (England, Northern Ireland, Wales and Scotland). We analysed policy documents, and conducted interviews with officials, stakeholders, NHS staff and public campaigners (total number of interviewees = 47). Involving the public in major service change was acknowledged as a policy challenge in all four systems. Despite ostensible similarities, there were some clear differences between the four health systems' processes for involving patients and the public in major changes to health services. The extent of central Government oversight, the prescriptiveness of Government guidance, the role for intermediary bodies and arrangements for independent scrutiny of contentious decisions all vary. We analyse how health policy in the four systems has used 'sticks' and 'sermons' to promote particular approaches, and conclude that both policy and the wider system context within which health care organisations try to effect change are significant, and understudied aspect of contemporary practice

Preliminary research informing policy on remote alcohol monitoring in criminal justice : the Scottish experience

This study was funded in part by a grant from the Scottish Violence Reduction Unit to Peter D Donnelly (no grant number) and partly by a grant from the Scottish School of Public Health to Fergus G Neville (no grant number).Objectives. To explore the views of Scottish offenders on the impact of alcohol on their experience of offending and their lives in general. Further, to explore their views on the concept of Remote Alcohol Monitoring (RAM) as a way to address alcohol misuse upon liberation from prison. Methods. A convenience sample of 12 serving offenders participated in one of three focus groups.Data were analysed using the principles of thematic analysis. Results. Analysis of the data revealed the significant impact of alcohol on the lives of the participants. Key themes included the amount and frequency of alcohol consumption; the association of alcohol with harm; the association of alcohol with offending; previous attempts to reduce alcohol consumption and possible reasons for failure; and the views of the participants on the utility of RAM in relation to crime prevention. Conclusions. This group of offenders had significant issues with alcohol misuse prior to incarceration that had impacted on their offending and resulted in a variety of health and social harms. Participants were generally positive but pragmatic about RAM, recognising that technology alone may not be enough to change deeply ingrained and addictive behaviours.PostprintPeer reviewe
