The purpose of this study was to specify the effects of alcohol on the performance of ship operators as a contribution to the development of new strategies against the risks of alcohol in water traffic. The nautical performance of 21 captains before and after alcohol consumption was assessed on a ship piloting simulator. The simulated scenarios represented passages of a container vessel through the German Bight. Performance was examined by nautical instructors according to standardised protocols. Mean (S.D.) blood alcohol concentrations (BACs) of 0.100 (0.024) g/dl before and 0.100 (0.017) g/dl after the performance trial resulted in striking effects on the nautical performance. The categories most severely affected were foresight and analysis of situation (impairment in 18 of 21 cases), concentration (impairment in 16 of 21 cases), accurateness, risk disposition and navigation (impairment in 15 of 21 cases). Chart work, preparation and communication were impaired in 12, 11 and 10 of 21 cases, respectively. None of the participants were capable to operate the simulated ship with an adequate safety after ingestion of alcohol. From these findings, and in consideration of the well-established impairment of a multitude of mental and physical functions by alcohol, it can be concluded that even low BACs bear high risks in water traffic, a concentration above 0.1 g/dl will hinder a sufficiently safe performance of ship operators. This should be considered in alcohol education and legislation. 相似文献

This reflection on major developments in the past, present, and future of the wider field of violence and trauma is a personal (and probably biased) sampling of what the authors hold to be important. The authors reviewed advances for victims and perpetrators of violence separately. For victims, the authors note that empirical research has established the potential traumatic impact of violence as well as various predictors of what makes persons vulnerable to adverse psychological consequences. The authors also note that the definitions of violence and trauma have evolved to include such behavioral patterns as stalking. Finally, encouraging evidence regarding the efficacy of exposure-based treatments for victims of violence is reviewed, as well as discouraging evidence regarding the efficacy of single-session debriefing following trauma. For the perpetrators, the importance of individual assessment in planning interventions is underscored, and advances in explicit and implicit assessment techniques are discussed. 相似文献

Professional decision making in forensic clinical practice may have lifelong consequences for offenders. Although information on moral development is important for prediction of reoffending and referral to adequate treatment, conclusions regarding moral development are still largely based on unstructured clinical judgment instead of assessment instruments. For this study, the authors examined to what extent unstructured clinical judgment of both moral judgment and victim empathy concurred with test results in a group of young sex offenders. Moral judgment was measured with the Sociomoral Reflection Measure-Short Form (SRM-SF), whereas victim empathy was measured with an extended version of the Basic Empathy Scale (BES). No significant associations were found between clinical judgment of moral judgment and the mean scores on the SRM-SF. However, clinical judgment of victim empathy was significantly associated with victim empathy on the Victim Empathy Scale but not consistently in the expected direction. Juvenile sex offenders, who were judged by clinicians to show little victim empathy, displayed lower mean scores on the Victim Empathy Scale than juvenile sex offenders who were evaluated to lack victim empathy or to have intact victim empathy. This study showed unstructured clinical judgment of moral development not to concur with test results. To improve decision-making processes regarding moral development, clinicians are advised to rely on instruments that assess moral development to inform clinical judgment. Further research is needed to examine which predictions are more accurate and to establish the predictive validity of moral development evaluations. 相似文献

A badly decomposed body required identification by means of DNA analysis. A brother and sister of the deceased were available as reference subjects. Although investigation of Y-chromosomal markers established an exclusion condition, autosomal markers suggested a positive identification. In order to increase the reliability of the tests, X-chromosomal markers were also investigated. This analysis showed the body to have an XXY genotype (Klinefelter's syndrome). A number of hypotheses were assessed using biostatistical methods, ultimately resulting in a definite identification. The special aspect of Klinefelter's syndrome proved highly useful for biostatistical analysis. 相似文献

The chemical analysis of fire debris represents a crucial part in fire investigations to determine the cause of a fire. A headspace solid‐phase microextraction (HS‐SPME) procedure for the detection of ignitable liquids in fire debris using a fiber coated with a mixture of three different sorbent materials (Divinylbenzene/Carboxen/Polydimethylsiloxane, DVB/CAR/PDMS) is described. Gasoline and diesel fuel were spiked upon a preburnt matrix (wood charcoal), extracted and concentrated with HS‐SPME and then analyzed with gas chromatography/mass spectrometry (GC/MS). The experimental conditions—extraction temperature, incubation and exposure time—were optimized. To assess the applicability of the method, fire debris samples were prepared in the smoke density chamber (SDC) and a controlled‐atmosphere cone calorimeter. The developed methods were successfully applied to burnt particleboard and carpet samples. The results demonstrate that the procedure that has been developed here is suitable for detecting these ignitable liquids in highly burnt debris. 相似文献

The neurosciences not only challenge assumptions about the mind’s place in the natural world but also urge us to reconsider its role in the normative world. Based on mind-brain dualism, the law affords only one-sided protection: it systematically protects bodies and brains, but only fragmentarily minds and mental states. The fundamental question, in what ways people may legitimately change mental states of others, is largely unexplored in legal thinking. With novel technologies to both intervene into minds and detect mental activity, the law should, we suggest, introduce stand alone protection for the inner sphere of persons. We shall address some metaphysical questions concerning physical and mental harm and demonstrate gaps in current doctrines, especially in regard to manipulative interferences with decision-making processes. We then outline some reasons for the law to recognize a human right to mental liberty and propose elements of a novel criminal offence proscribing severe interventions into other minds. 相似文献
