AmpFlSTR profiler Plus short tandem repeat DNA analysis of casework samples, mixture samples, and nonhuman DNA samples amplified under reduced PCR volume conditions (25 microL)

As part of the validation of the AmpFlSTR Profiler Plus short tandem repeat (STR) system, under reduced polymerase chain reaction (PCR) volume conditions (i.e., 25 microL), a total of 275 casework samples were processed. Examples of profiles are presented along with amplification conditions to improve the odds of obtaining balanced and complete profiles for samples showing partial results or profiles with a descending slope. Data collected and used to develop our interpretation guidelines are included. From the mixture studies, full profiles were obtained for minor contributors, using 2 ng of DNA, with ratios of 10:1 or 1:20 and using 1 ng of DNA, with ratios of 10:1 and 1:8. The specificity of the Profiler Plus amplification reaction performed in 25 microL was examined and confirmed using a large spectrum of nonhuman DNAs. This report supports the use of the AmpFlSTR Profiler Plus STR system for casework DNA typing under reduced PCR volume conditions.     

Eyewitness Memory,Suggestibility, and Repeated Recall Sessions in Children with Mild and Moderate Intellectual Disabilities

This study of eyewitness memory questioned children with mild and moderate intellectual disabilities (ID) about a live staged event 1 day later and, again, 2 weeks later. Children with mild ID performed as well as typically-developing children of the same age in response to free recall instructions, and they were just as able as same age peers to resist misleading questions. However, they performed more poorly on general questions, probing for further information after free recall. The children with mild ID also changed their responses to specific questions more often in the repeated interview. The group of children with moderate ID showed markedly lower performance than peers of the same age on nearly every type of eyewitness memory question. Comparisons of the children with ID to mental age-matched peers indicated that performance was similar, although children with ID gave more information in response to free recall instructions and changed their answers in the repeated interview more often. Standardized measures of verbal memory (TOMAL) and suggestibility (Gudjonsson Suggestibility Scale) were modest to moderate predictors of eyewitness memory performance.     

The Place of Wishes and Feelings in Best Interests Decisions: Wye Valley NHS Trust v Mr B

In Wye Valley NHS Trust v Mr B the Court of Protection decided that it was not in the best interests of Mr B to receive amputation surgery against his will, notwithstanding that he would die without the treatment. The judge met with Mr B in person and his best interests decision placed significant weight on Mr B's wishes and feelings. This case note considers this influential case in the context of ongoing debate about the place of wishes and feelings in best interests decisions under the Mental Capacity Act 2005. It considers the history of the best interests principle, its interpretation by the Supreme Court in Aintree University Hospitals NHS Foundation Trust v James, ongoing debates about its compatibility with Article 12 of the United Nations Convention on the Rights of Persons with Disabilities, and recent proposals by the Law Commission for statutory amendments to the Mental Capacity Act.     

Stable isotope profiling of burnt wooden safety matches

Arson is a significant problem around the world, and is a crime which results in a low number of convictions. The scene of an arson can be varied, commercial, residential or national park, and recently cases have been identified which were initiated by a lit match. Matches can be recovered from a scene, usually in a burnt condition. The benefit of analysing unburnt matches has been researched previously [1,2]. In most cases, burnt matches are recovered from scenes, and therefore the research was extended to investigate the potential of using IRMS to analyse burnt matches. This includes samples which have been exposed to petrol, and various fire extinguishing chemicals.Matches were sectioned to reveal central unburnt portions of wood and analysed by isotope ratio mass spectrometry (IRMS). The stable isotope profile (SIP) of the wooden matchstick samples was unaffected by the presence of both petrol and a variety of fire extinguisher chemicals. Any changes seen could be attributed to the natural variability of isotopic composition encountered in a natural material such as wood. These findings were confirmed by the isotope analysis of 19 matchstick samples placed in mock fire training scenarios. The data was examined using a paired t-test and Hotellings T² test for a single sample.     

from pillar to post: understanding the victimisation of women and children who experience domestic violence in an age of austerity

The dismantling of the welfare state across the United Kingdom (and indeed a number of other Western industrialised democracies, such as Canada and the United States) and the reductions to welfare provisions and entitlements are having a detrimental impact on women’s equality and safety. Towers and Walby argue that the recent cuts to welfare provision in the United Kingdom, particularly for women’s services, could lead to increased levels of violence for women and girls. This paper makes the argument that female victims of domestic abuse experience violence on two levels: first, at the intimate/personal level through their relationship with an abuser and, second, at a structural level, through the state failing to provide adequate protection and provision for women who have experienced violence in intimate relationships. Using a specific example of post-violence community services delivered to both the children of women who have experienced domestic violence and the women themselves, this paper draws on empirical research carried out in 2010–2011 with London-based third-sector and public sector organisations delivering the Against Violence and Abuse Project ‘Community Group Programme’. We argue that the lack of services for women involved in, or exiting, a violent relationship can amount to state-sanctioned violence, if funding is withheld, or indeed, stretched to breaking point.     

Fault Lines: The Effects of Bureaucratic Power on Electoral Accountability

This article introduces a new explanation for why citizens may fail to vote based on government performance. We argue that when politicians have limited capacity to control bureaucrats, citizens will not know whether government performance is a good signal of the incumbent's quality. We develop a selection model of elections in which policy is jointly determined by a politician and a bureaucrat. When politicians have incomplete power over policy, elections perform worse at separating good and bad types of incumbents. We test the theory's predictions using survey experiments conducted with nearly 9,000 citizens and local officials in Uganda. We find that citizens and officials allocate more responsibility to politicians when they are perceived as having more power relative to bureaucrats. The allocation of responsibility has electoral consequences: When respondents believe that bureaucrats are responsible for performance, they are less likely to expect that government performance will affect incumbent vote share.     

The Effects of Changes to Legal Aid on Lawyers' Professional Identity and Behaviour in Summary Criminal Cases: A Case Study

This article explores the effects of changes to legally aided representation on criminal cases in magistrates' courts according to data collected in an area of south‐east England. I consider the political factors that motivated changes to legal aid and suggest how these issues affecting lawyers' understanding of their role, and how that understanding affects the relationships between defendants, lawyers, and the magistrates' courts. I argue that the research indicates a potential relation between solicitors' risk‐taking behaviour in obtaining funding and the reintroduction of means testing: remuneration rates affect the service that defendants receive and the reintroduction of means testing decreased efficiency in summary criminal courts. Ultimately, I argue that changes to legal aid funding have increased lawyers' uncertainty about their role, leaving them torn between acting efficiently and providing a good level of service.     

A ‘double edged sword’: discretion and compulsion in policing domestic violence

Policing domestic violence is a complex area in which there are divergent views about the extent to which front line police action should be mandated by legislation and guidance. This study set in Victoria, Australia raised questions about the balance between discretion and compulsion in policing domestic violence through researching the implementation of the Code of Practice used to respond to domestic violence incidents. The project team interrogated aggregate data from the police database on family violence and also interviewed 125 police members (60 sergeants and 65 constables) to explore the attitudes to the Code of Practice and policing domestic violence. The findings reveal that discretion within a range of options is circumscribed. Variable understandings of the nature of domestic violence and the role of risk assessment and management suggest that constrained and guided discretion may be required to achieve optimum effectiveness in policing responses to domestic violence.
