Comparison of presumptive blood test kits including hexagon OBTI

Four presumptive blood tests, Hexagon OBTI, Hemastix(R), Leucomalachite green (LMG), and Kastle-Meyer (KM) were compared for their sensitivity in the identification of dried bloodstains. Stains of varying blood dilutions were subjected to each presumptive test and the results compared. The Hexagon OBTI buffer volume was also reduced to ascertain whether this increased the sensitivity of the kit. The study found that Hemastix(R) was the most sensitive test for trace blood detection. Only with the reduced buffer volume was the Hexagon OBTI kit as sensitive as the LMG and KM tests. However, the Hexagon OBTI kit has the advantage of being a primate specific blood detection kit. This study also investigated whether the OBTI buffer within the kit could be utilized for DNA profiling after presumptive testing. The results show that DNA profiles can be obtained from the Hexagon OBTI kit buffer directly.     

Evaluation of structured cognitive–behavioural treatment programmes in reducing criminal recidivism

This paper reports the outcome of a 17-month follow-up of structured, community-based, offence-focused, intervention programmes designed to reduce rates of re-conviction amongst adjudicated offenders under probation supervision. Three separate programmes were examined, all derived from a cognitive social learning model of risk factors for repeated involvement in crime. Using a quasi-experimental design, the study compared male offenders who had completed programmes (n = 215) with a non-completion group (n = 181), a group allocated to programmes but who had not commenced them (n = 339), and a control sample (n = 194) not allocated to the programmes. Outcome data analysis employed (a) an “intent to treat” between-group comparison, (b) “treatment received” methodology. In order to take account of selection bias, data were further analysed using instrumental variables and propensity scores; results suggested a possible treatment effect for moderate and higher-risk cases. Factors influencing different interpretations of these findings were considered.

Tariff liberalization and product standards: Regulatory chill and race to the bottom?

Does tariff liberalization cause regulatory chill by putting downward pressure on health, safety, and environmental standards? Or does it cause a race to the top as governments seek to use standards as nontariff barriers to trade? There remains remarkably little empirical evidence to answer these long-debated questions. We seek to address this lack by analyzing annual country-by-industry data on notifications of changes in sanitary and phytosanitary standards by world trade organization members. Our results suggest that the impact of increased trade pressure depends on whether domestic producers are likely to gain or lose from a change in standards. Regulatory chill is the dominant response in most countries, but countries in which producers can adapt to standards relatively cheaply appear to race to the top. Consequently, tariff liberalization encourages divergence in standards across countries.     

‘She’s White and She’s Hot,So She Can’t Be Guilty’: Female Criminality,Penal Spectatorship,and White Protectionism

Despite mainstream criminology’s burgeoning interest in issues of race, class, and gender, very little scholarship has examined whiteness and its attendant privileges in understanding public discourse on criminal offenders. This paper examines the role of penal spectatorship as a discursive mechanism by which white, female offenders are protected in public spaces by virtue of their racial and gender identity. Using a content analysis of comments posted on the mug shot images of white women on a popular ‘mug shot website,’ we find that these women are viewed as victims of circumstance deserving of empathy and redemption rather than as criminals. We offer ‘white protectionism’ as a means by which whites extend privilege and protection to other whites who transverse the boundaries of whiteness through criminality to guard against ‘deviant’ or ‘criminal’ designations. These findings add to our understandings of penal spectatorship as yet another tool of white supremacy operating in the Post-Civil Rights era of mass incarceration.     

Measuring Innovation – Applying the Literature-Based Innovation Output Indicator to Public Services

Governments have been encouraging public service organizations to innovate. However, little is known about the extent of innovation in public service organizations. A private sector approach to the measurement of innovation - the literature-based innovation output indicator (LBIOI) - is applied to public service organizations to address this significant information gap. The method is described and then explored in one public service sector, English housing associations. A sample of 257 innovations is constructed and then subject to analysis. This initial testing of the LBIOI indicates that the approach can be applied across public services to create longitudinal data sets, which will enhance the communication of good practice and the use of evidence in public policy, management and research. This methodology is demonstrated to offer initial insights to public service innovation and would allow relationships to be explored notably innovation and performance, a relationship central to government's promotion of innovation.
