Differences in trauma symptoms and family functioning in intra-and extrafamilial sexually abused adolescents

This study investigated to what extent abuse-related symptoms and family functioning are related to intra- or extrafamilial sexual abuse. One hundred adolescents (12 to 18 years old) were recruited shortly after disclosure of the abuse. Information from the participants was obtained through self-report questionnaires and a semistructured interview. Fifty-three percent of the adolescents reported clinically significant symptoms. Data did not support the idea that intrafamilial sexually abused adolescents report more symptoms than extrafamilial sexually abused adolescents. Type of abuse did not account for the differences and variety of reported symptoms or for differences in family functioning. Family functioning-in particular, lack of cohesion- was an independent contributor to internalizing trauma-related problems.     

Intentional and unintentional injuries across health regions in Alberta, Canada: an implication for policy

The growing practice of including intentional injuries (suicide and interpersonal violence) under the injury control umbrella has produced some controversy. The present study was designed to determine whether or not there might be an empirical basis for this initiative from an ecological point of view by examining the associations among unintentional and intentional injuries across 17 geographically defined health regions. The study was set in the Province of Alberta, Canada, where health services were delivered to a population of 2.96 million persons in 1999 through 17 regional health authorities. The results of a principal components analysis showed that nearly all causes of injury-hospitalization loaded on a single factor. It was not possible to produce separate factors for intentional and unintentional injuries. The strong intercorrelation among all measures suggests that there is an empirical basis for the view that intentional and unintentional injuries belong under the same conceptual umbrella, at least at the ecological level.     

Childhood panhypopituitarism presenting as child abuse: a case report and review of the literature

Childhood panhypopituitarism may be acquired or congenital. Children with panhypopituitarism can present clinically with diabetes, growth failure, decreased bone density, and morbid obesity. In the forensic setting without the proper history, it can be misdiagnosed as child abuse or neglect. We report a case of a 3-year-old black girl who was admitted to the emergency room with apnea and subsequently died. While at the emergency department, it was discovered that the child had a fractured left hip and was severely growth retarded for age. The coroner wanted to rule out child abuse and/or neglect and requested an autopsy based on the physical findings identified by hospital staff. Significant findings at autopsy included small for age (15th percentile for age), hypoplastic brain/pituitary gland/adrenal gland/thyroid gland, abnormally formed skull with an occipital protuberance, a fractured left hip with decreased bone density, and central adiposity. Subsequent to the autopsy, it was discovered that at 6 weeks of age the child suffered from group B streptococci meningitis that resulted in panhypopituitarism. The panhypopituitarism then resulted in seizure activity, diabetes insipidus, and growth retardation. The authors hope this case report and review of the literature will assist investigators, pathologists, and clinicians in making a distinction between neglect or inflicted injury of child abuse and panhypopituitarism that can present with similar signs and symptoms.     

Interpretation of a 3,4-methylenedioxymethamphetamine (MDMA) blood level: discussion by means of a distribution study in two fatalities

The amphetamine derivative 3,4-methylenedioxymethamphetamine (MDMA, "Ecstasy" is a currently used or abused designer drug and fatalities are frequently encountered in forensic practice. However, the question remains open whether an MDMA blood level can be toxic or even potentially lethal. In order to provide insight in the interpretation of a detected MDMA concentration, the distribution of MDMA and its metabolite 3,4-methylenedioxyamphetamine (MDA) in various body fluids and tissues was studied and discussed in two different fatalities. Apart from peripheral blood samples (such as femoral and subclavian blood), various blood samples obtained centrally in the human body and several body fluids (such as vitreous humour) were examined. In addition, various tissues such as cardiac muscle, lungs, liver, kidneys, and brain lobes were analysed. In contrast to the peripheral blood levels, high MDMA and MDA levels were found in cardiac blood and the majority of the organs, except for the abdominal adipose tissue. The high concentrations observed in all lung lobes, the liver and stomach contents indicate that post-mortem redistribution of MDMA and MDA into cardiac blood can occur and, as a result, blood sampled centrally in the body should be avoided. Therefore, our data confirm that peripheral blood sampling remains "the golden standard". In addition, a distinct difference in peripheral blood MDMA concentrations in our two overdose cases was established (namely 0.271 and 13.508 microg/ml, respectively). Furthermore, our results suggest that, if a peripheral blood sample is not available and when putrefaction is not too pronounced, vitreous humour and iliopsoas muscle can be valuable specimens for toxicological analysis. Finally, referring to the various mechanisms of death following amphetamine intake, which can result in different survival times (e.g. cardiopulmonary complications versus hyperthermia), the anatomo-pathological findings and the toxicological results should be considered as a whole in arriving at a conclusion.     

Patent Related Indicators for Assessing Knowledge-Generating Institutions: Towards a Contextualised Approach

This contribution aims at examining the extent to which patent related indicators are relevant for shedding light on the notion of excellence within knowledge-generating institutions. Traditionally, excellence has been looked upon as the ability to create interesting and valuable new scientific concepts, theories and data. From such a perspective, scientific excellence can be assessed through scientometric measures of publication output and impact. The recent interest in the entrepreneurial phenomenon within knowledge-generating institutes justifies efforts to examine the relevancy of broadening the set of indicators used to assess such institutions into the direction of entrepreneurial excellence. In this paper we will examine the relevancy of using patent data in order to delineate such additional, more entrepreneurial oriented, indicators. The arguments and findings presented in this respect will lead us to a plea for the use of these indicators in a contextualized manner.     

The Illusion of Transparency in Negotiations

The authors examined whether negotiators are prone to an illusion of transparency, or the belief that their private thoughts and feelings are more discernible to their negotiation partners than they actually are. In Study One, negotiators who were trying to conceal their preferences thought that their preferences had leaked out more than they actually did. In Study Two, experienced negotiators who were trying to convey information about some of their preferences overestimated their partners' ability to discern them. The results of Study Three rule out the possibility that the findings are simply the result of the curse of knowledge, or the projection of one's own knowledge onto others. Discussion explores how the illusion of transparency might impede negotiators' success.     

A potential metallographic technique for the investigation of pipe bombings

This study was conducted in an attempt to develop a metallographic method for the investigation of pipe bombings. Three common pipe materials, ASTM A53 steel, AISI 304L stainless steel, and 6061-T6 aluminum, were shock-loaded using five high explosives and three propellants. The explosives used were ANFO, Composition C4, C6 detasheet, nitroglycerine-based dynamite, and flake TNT. The propellants used were FFFFg black powder. Red Dot smokeless powder, and Turbo Fuel A. The post-blast microstructure, hardness, and, in the case of 304L, transformed martensite content were examined for each test. The damage done to the microstructure was found to increase with increasing detonation velocity of the explosives and increase in pressure generated by the shock-metal interaction. Material hardness and, in the case of 304L, martensite content showed a sharp increase followed by a plateau as the shock pressure and detonation velocity increased.
