Development of an immunoassay for the differentiation of menstrual blood from peripheral blood

This study examined all unintentional firearm fatalities while hunting that occurred in Sweden between 1983 through 2008. The circumstances as well as the impact of the hunter's exam on fatality frequency were analysed. During these 26 years, there were 48 such fatalities, representing 53% of all (n=90) unintentional firearm deaths during the same period. The average annual number of fatalities decreased over the last few decades. Very restrictive firearm legislation in Sweden combined with the introduction of a mandatory hunter's exam since 1985 accounted, at least partly, for this finding. Moose hunting accounted for 46% of the fatalities and small game hunting for the remaining cases. The mean age of the victims was 50 years and 96% of them were males; all shooters were males. During moose hunting, most of the victims were mistaken for game, whereas in small game hunting most of the fatalities were related to falls and improper handling of the weapon. Human error was thus the main cause of these fatalities.     

The Impact of Funding Modalities on the Performance of Indigenous Organisations

Governments’ choice of funding modality can produce powerful incentives for organisations to perform in preferred ways, but it can also divert limited resources, narrow accountability, and undermine capability. Through literature review and interviews, the research explored the international literature on public finance management in developing country contexts, and compared this to case studies of Indigenous organisations. The situation in Australia was found to differ in three ways: (1) performance indicators are imposed, rather than negotiated; (2) few existing public funding modalities reward performance or provide incentives; and (3) funding arrangements do not generally require receiving organisations to be accountable to their constituents. Stability and durability of funding modalities, and clarity in functions and jurisdictional boundaries, were also found to positively influence performance. Further research is required to design new performance frameworks that build around the organisation, rather than the grant, with indicators of governance capability and downward accountability to constituents.     

The dynamic character of disguise behavior for text-based, mixed, and stylized signatures

The aims of this study were to determine if dynamic parameters (duration, size, velocity, jerk, and pen pressure) differed for signing style (text-based, stylized, and mixed) and if signing style influences handwriting dynamics equally across three signature conditions (genuine, disguised, and auto-simulation). Ninety writers provided 10 genuine signatures, five disguised signatures, and five auto-simulated signatures. All 1800 signatures were collected using a digitizing tablet resulting in a database of each signature's dynamic characteristics. With genuine signatures, there were significant differences between styles for size, velocity, and pen pressure, and there were significant differences between genuine signatures and at least one of the un-natural signature conditions for all parameters. For velocity and size, these changes with condition were dependent on style. Changes with condition for the other parameters were similar for the three styles. This study shows that there are differences among natural signature styles and disguise behaviors that may be relevant in forensic signature examinations.     

First-time DWI offenders are at risk of recidivating regardless of sanctions imposed

Objective

Research demonstrates that punitive approaches to DWI employed by the judiciary have failed to significantly reduce recidivism. However, little is known about the deterrent effects of administrative and diversion sanctions. We examine whether such sanctions deter first-time DWI offenders.

Methods

We grouped combinations of administrative, judicial, and diversion sanctions routinely employed in the state of Maryland for processing drivers arrested for DWI into one of eight mutually exclusive disposition sequences. We applied this classification to Maryland drivers who had been licensed in the state and had precisely one DWI on their record prior to January 1, 1999. We then used a proportional hazards model to estimate the probability of remaining free of a new DWI during a 6-year period (January 1, 1999 - December 31, 2004) as a function of the disposition of the index violation, and of selected factors that could affect that probability.

Results

Drivers with a prior DWI were at relatively high risk of recidivating regardless of how they were sanctioned. Those who received administrative and alternative sanctions had a risk of recidivating similar to that of drivers who were convicted.

Conclusion

All dispositions sequences, not just convictions, indicate that first-time DWI offenders are at high risk of recidivating.     

Implementation of the Americans with Disabilities Act in State Police and Highway Patrol Agencies: Results of a National Survey

This article provides an empirical analysis of Americans with Disabilities Act (ADA) implementation within the law enforcement profession. Specifically, the study reports results from a national survey of state police/highway patrol agencies regarding practical implementation of the ADA. The data is analyzed in terms of population size and collective bargaining status. Results of this endeavor indicate that implementation of the ADA within law enforcement is difficult, especially as applied to the work of sworn personnel. These challenges are somewhat diminished when applied to non-sworn personnel such as dispatchers, administrators, and clerical personnel. The most substantial obstacles to implementation of the ADA within law enforcement is not associated with political officials or administrators. Instead, most arise from the lack of training and vague legislative language and regulatory standards. Smaller states and those without collective bargaining report lower levels of accommodation; however, there are few statistically significant differences in terms of population and collective bargaining.     

Alternative fuels in fire debris analysis: biodiesel basics

Alternative fuels are becoming more prominent on the market today and, soon, fire debris analysts will start seeing them in liquid samples or in fire debris samples. Biodiesel fuel is one of the most common alternative fuels and is now readily available in many parts of the United States and around the world. This article introduces biodiesel to fire debris analysts. Biodiesel fuel is manufactured from vegetable oils and/or animal oils/fats. It is composed of fatty acid methyl esters (FAMEs) and is sold pure or as a blend with diesel fuel. When present in fire debris samples, it is recommended to extract the debris using passive headspace concentration on activated charcoal, possibly followed by a solvent extraction. The gas chromatographic analysis of the extract is first carried out with the same program as for regular ignitable liquid residues, and second with a program adapted to the analysis of FAMEs.
