Fatal crossbow injury in an adolescent

The authors present the case of a 14-year-old boy who died while handling a crossbow, which was a gift from a friend's mother. The bolt passed through the right nostril, penetrated the sinus sphenoidalis, the brain stem, the left occipital lobe and the occipital calvaria. Immediately after the accident, the victim was taken to a maximum care hospital. In spite of neurosurgical treatment and intensive care the victim died 4 days later. The case presented demonstrates that crossbows are not suitable as toys for underage persons, as they are deadly weapons which can cause serious penetrating injuries. In Germany, no license is required to buy and/or possess crossbows. In the authors' opinion, legal restrictions on the sale of crossbows and a special training of the users would be reasonable measures to reduce such accidents.     

Psychological profile of male and female animal abusers

This study had three purposes: to explore psychological characteristics of animal abusers (criminal thinking styles, empathy, and personality traits), to replicate previously reported results (past illegal actions, bullying behavior), and to examine potential gender differences. The self-reported animal abuser group was 29 college students who reported two or more incidents of animal abuse; controls were 29 college students matched on age and gender. Participants completed self-report measures of criminal thinking, illegal behaviors, bullying, empathy, and the five-factor personality traits. Results indicated animal abusers had more previous criminal behaviors, were more likely to bully, and had the highest scores on the power orientation criminal thinking scale. Abuser by gender interactions were detected; female animal abusers scored significantly higher on several measures of criminal thinking, were found to be more likely to bully, and exhibited lower scores on measures of perspective taking and empathy compared to female controls.

Prevalence and correlates of physical spousal violence against women in slum and nonslum areas of urban Bangladesh

This study explores the prevalence and correlates of past-year physical violence against women in slum and nonslum areas of urban Bangladesh. The authors use multivariate logistic regression to analyze data from the 2006 Urban Health Survey, a population-based survey of 9,122 currently married women aged between 15 and 49 who were selected using a multistage cluster sampling design. The prevalence of reported past-year physical spousal violence is 31%. Prevalence of past-year physical spousal violence is higher in slums (35%) than in nonslums (20%). Slapping/arm-twisting and pushing/shaking/ throwing something at the women are the most commonly reported acts of physical abuse. Multivariate analysis shows that the risk of physical spousal abuse is lower among older women, women with post-primary education, and those belonging to rich households and women whose husbands considered their opinion in decision making. Women are at higher risk of abuse if they had many children, believe that married woman should work if the husband is not making enough money, and approve wife-beating norms. This study serves to confirm the commonness of physical spousal abuse in urban Bangladesh, demonstrating the seriousness of this multifaceted phenomenon as a social and public health issue. The present findings suggest the need for comprehensive prevention and intervention strategies that capitalize on the interplay of individual and sociocultural factors that cause physical spousal violence. Our study adds to a growing literature documenting domestic violence against women in urban areas of developing south Asian nations.     

Evaluation of vapor profiles of explosives over time using ATASS (Automated Training Aid Simulation using SPME)

Despite numerous instrumental achievements, canines are still considered the most effective field method for explosive detection. However, due to strict explosive regulations and safety requirements, it can be a challenge for agencies with "bomb dogs" to train using neat explosive materials. This establishes a need for non-explosive canine training aids with the same volatile component profiles as the explosives that they represent. In order to compare mimic materials to their explosive counterparts, a technique must be established that not only allows for identification of volatile compounds but also can monitor changes in the headspace profile over time with respect to time and temperature. The Automated Training Aid Simulation using SPME (or ATASS) was developed for that purpose. As described, ATASS was used to observe changes in the volatile profile of three explosives (Composition C-4, 2,4-dinitrotoluene (DNT), and triacetone triperoxide (TATP)) and respective prototype training materials (0.1% by mass C-4, 1% by mass 2,4-DNT, and 1% by mass TATP). Samples were prepared in vials and metal tins within a gallon (≈ 3785 mL) paint can to simulate common field techniques for canine training. Monitoring these materials in real time provides a better understanding of the major volatile components present and how the relative abundances of these components can change over time. The results presented indicate that ATASS successfully allows for a sufficient comparison between explosive and non-explosive training materials.     

Detection of ethyl glucuronide in blood spotted on different surfaces

This study aims to show that sensitive detection of ethyl glucuronide in dried blood spotted onto various surfaces after a period of 24h is feasible. At present, there is insufficient information how tightly ethyl glucuronide (EtG) binds to various materials and how easily it can be eluted. 4ml aliquots of blood samples obtained from seven volunteers after consumption of alcoholic beverages were applied to six different surfaces. After drying and a 24h-storage at 20±2°C the samples were re-dissolved in water, and EtG was subsequently analyzed by a LC-MS Paul-type ion trap. A comparison was made between dried and corresponding fluid samples. EtG was detectable in all subjects' samples following consumption of alcohol. EtG was also detectable after a storage time of four weeks at 4°C in whole blood that had been preserved with EDTA. EtG was detectable in all samples dried on different surfaces and its concentration remained relatively constant irrespective of the particular condition of the material. Detection of EtG in blood spots from the scene may indicate recent alcohol consumption in cases where collection of blood remained undone or could not be performed.     

Reliability reporting across studies using the Buss Durkee Hostility Inventory

Empirical research on anger and hostility has pervaded the academic literature for more than 50 years. Accurate measurement of anger/hostility and subsequent interpretation of results requires that the instruments yield strong psychometric properties. For consistent measurement, reliability estimates must be calculated with each administration, because changes in sample characteristics may alter the scale's ability to generate reliable scores. Therefore, the present study was designed to address reliability reporting practices for a widely used anger assessment, the Buss Durkee Hostility Inventory (BDHI). Of the 250 published articles reviewed, 11.2% calculated and presented reliability estimates for the data at hand, 6.8% cited estimates from a previous study, and 77.1% made no mention of score reliability. Mean alpha estimates of scores for BDHI subscales generally fell below acceptable standards. Additionally, no detectable pattern was found between reporting practices and publication year or journal prestige. Areas for future research are also discussed.
