The New Forest Suicide Prevention Initiative (NFSPI)

A retrospective suicide study revealed that the Forestry Commission car parks in the New Forest in southern England were a previously unrecognized magnet for nonlocal suicides, attracting as high a proportion of "visitors" (35/43 in 1993-97) as among suicides who jumped from the cliffs at the infamous Beachy Head (39/48 in 1993-97). Over 95% of the car park suicides died from car exhaust gas poisoning. A multiagency initiative aimed to reduce the number of suicides in the 140 New Forest car parks where restricting access was impossible, and environmental issues paramount. Signs displaying the Samaritans' national telephone number were erected in the 26 car parks in which 50% of the car park suicides had occurred. Numbers, location, and residence of all car park deaths were monitored for 3 years. Corresponding changes in other forest registration districts were also monitored. During the 3-year intervention period the number of car park suicides fell significantly from 10/year, 1988-1997, to 3.3/year. The average annual total number of suicides in the New Forest registration district also decreased. No significant changes were found in comparable forest districts. The number of suicides in the New Forest car parks remained low during the 2 years following the evaluation.     

A new approach to amino acid racemization in enamel: testing of a less destructive sampling methodology

Aspartic acid racemization has been found to be an accurate measure of age at death for recent forensic material. This paper examines the practicality of using acid etching of the tooth surface to extract amino acids from the enamel for racemization analysis. By serial etching of the tooth and contamination of the teeth with bovine serum albumin prior to etching, the ability of etching to remove contamination was assessed. The destructiveness of the method was visualized and quantified using micro-computed tomography (micro-CT). By bleaching the teeth and by deeper etching it was possible to obtain more consistent values. While etching had little effect on the enamel at the macroscale, it did have an impact at the microscale. The quantities of enamel removed varied depending upon the tooth morphology, but were not large. Acid etching of enamel thus appears to be a promising new method for extracting proteins for amino acid racemization age estimation noninvasively.     

Excretion of Delta9-tetrahydrocannabinol in sweat

The aims of this study were: first, to determine the accuracy of the Cameriere method for assessing chronological age in children based on the relationship between age and measurement of open apices in teeth and, second, to compare the accuracy of this method with the widely used Demirjian et al. method and with the method proposed by Willems et al. Orthopantomographs taken from white Italian, Spain and Croatian children (401 girls, 355 boys) aged between 5 and 15 years were analysed following the Cameriere, Demirjian and Willems methods. The difference between chronological and dental age was calculated for each individual and each method (residual). The accuracy of each method was assessed using the mean of the absolute values of the residuals (mean prediction error). Results showed that the Cameriere method slightly underestimated the real age of children. The median of the residuals was 0.081 years (interquartile range, IQR=0.668 years) for girls and 0.036 years for boys (interquartile range, IQR=0.732 years). The Willems method showed an overestimation of the real age of boys, with a median residual error of -0.247 years and an underestimation of the real age of girls (median residual error=0.073 years). Lastly, the Demirjian method overestimated the real age of both boys and girls, with a median residual error of -0.750 years for girls and -0.611 years for boys. The Cameriere method yielded a mean prediction error of 0.407 years for girls and 0.380 years for boys. Although the accuracy of this method was better for boys than for girls, the difference between the two mean prediction errors was not statistically significant (p=0.19). The Demirjian method was found to overestimate age for both boys and girls but the mean prediction error for girls was significantly greater than that for boys (p=0.024), and was significantly less accurate than the Cameriere method (p<0.001). The Willems method was better than that of Demirjian (p=0.0032), but was significantly less accurate than that of Cameriere (p<0.001).     

Cumulative experiences of violence among high-risk urban youth

This study examines type-specific and cumulative experiences of violence among a vulnerable population of youth. Sixty high-risk, shelter-dwelling, urban youth were interviewed regarding their history of childhood maltreatment, exposure to community violence (ECV), and experience with intimate partner violence (IPV). Results show a high prevalence and high degree of overlap among multiple types of violence exposure. Childhood physical, sexual (CSA), and emotional (CEA) abuse were interrelated and were associated with ECV. Cumulative experiences of childhood abuse (CCA) had a graded association with IPV victimization. In multivariate analyses, CCA and ECV were independently associated with IPV victimization. Gender moderated the effect of one association: CEA raised the risk of IPV victimization for girls but not for boys. Only CSA predicted IPV perpetration. Findings suggest that cumulative exposures to violence create cumulative risk for experiencing more violence. Shelter-dwelling, urban youth may be particularly vulnerable to this additive effect.     

The impact of pretrial publicity on jurors

Previous research on how jurors are prejudiced by pretrial publicity (PTP) has focused on the impact of print media (i.e., newspapers). However, in this “television age”, we are exposed to compelling and vivid images of crimes and cases. This raises the question of whether potential jurors may be more influenced by television media (e.g., news programs or televised hearings) then print media (e.g., newspaper and magazine articles). Using an actual case involving extensive PTP, the present study varied the type of medium (print articles, video, articles+video) presented to potential jurors. The results indicated that exposure to the various media had a prejudicial impact on people, and that they were unaware of their biases. As hypothesized, television exposure and television plus print articles biased potential jurors significantly more than exposure to print media alone.     

Towards a model of effective knowledge transfer within transnationals: The case of Chinese foreign invested enterprises

In this paper Chinese foreign invested enterprises (FIEs) are employed as prototypes to generate a model of how transnationals can transfer both tacit and explicit knowledge between their units as well as between FIEs and the parent organization. We propose that successful intra-organization knowledge transfer depends upon: (1) collective creation of knowledge as intellectual and social capital available throughout the organization; (2) trust-based collaboration among geographically dispersed entities that form the transnational organization; and (3) the willingness and ability of organizational units to use that knowledge. The paper further proposes that organizational knowledge should ideally flow in multiple directions, providing learning opportunities for both investing and host organizations. Implications for transfer of best practices, a specific form of tacit knowledge, are also offered.     

The Maastricht-Urteil: Sovereignty Now

Abstract: The sovereignty issue in European law, which was recently raised again before the highest national courts, poses a challenge to legal theory. The supremacy of EC law should not be regarded as imposing a strict hierarchy within a monistic legal system. A pluralistic and interactive analysis of the relations between the legal systems of the Member States and their common system of EC law suggests instead that the highest court within each system retains interpretative competence-competence. Although pluralist legal theory therefore supports the claim that sovereignty has not passed to the organs of the Union, the same analysis confirms that sovereignty has not remained with the individual Member States either: a more subtle understanding of the meaning of sovereignty and its locus is necessary.
