Sex determination and estimation of stature from the long bones of the arm

The determination of sex and the estimation of stature from bones play an important role in identifying unknown bodies, parts of bodies or skeletal remains. In medico-legal practice statements on the probable sex of a decomposed body or part of a body are often expected even during autopsy. The present study was, therefore, restricted to few easily accessible dimensions from bones which were prepared only by mechanically removing soft tissues, tendons and ligaments. The specimens came from the Anatomical Institutes in Munich and Cologne from the years 1994-1998 including a total of 143 individuals (64 males and 79 females). The mean age was 79 years (46-108), the mean body height 161cm (134-189). The following measurements were taken: maximum humeral length (mean: 33.4cm in males; 30.7cm in females), vertical humeral head diameter (mean: 5.0cm in males, 4.4cm in females), humeral epicondylar width (mean: 6.6cm in males; 5.8cm in females), maximum ulnar length (mean: 26.5cm in males, 23.8cm in females), proximal ulnar width (mean: 3.4cm in males, 2.9cm in females), distal ulnar width (mean: 2.2cm in males; 1.8cm in females), maximum radial length (mean: 24.6cm in males; 22.0cm in females), radial head diameter (mean: 2.6cm in males, 2.2cm in females) and distal radial width (mean: 3.6cm in males; 3.2cm in females). The differences between the means in males and females were significant (P<0.0005). A discriminant analysis was carried out with good results. A percentage of 94.93% of cases were correctly classified when all measures of the radius were applied jointly, followed by humerus (93.15%) and ulna (90.58%). Applied singly, the humeral head diameter allowed the best distinction (90.41% correctly grouped cases), followed by the radial length (89.13%), the radial head diameter (88.57%) and the humeral epicondylar width (88.49%). The linear regression analysis for quantifying the correlation between the bone lengths and the stature led to unsatifactory results with large 95%-confidence intervals for the coefficients and high standard errors of estimate.     

Effects of profound hypothermia on the blood-brain barrier permeability in acute and chronically ethanol treated rats

This study examines the effects of profound hypothermia on the blood-brain barrier (BBB) permeability in ethanol administrated rats. Vascular permeability to intravenously injected Evans blue (EB) was quantitatively examined in the brain regions of rats. Rats were treated with ethanol acute and chronically. Rectal temperature of rats was dropped into 20+/-1 degrees C during profound hypothermia. Mean arterial blood pressure in both acute and chronic ethanol treatments plus hypothermia significantly dropped into low levels as well as in hypothermia alone (P<0.01). Hypothermia led to a significant increase in the content of EB dye in the brain regions of rats (P<0.05). Both acute and chronic ethanol treatments plus hypothermia did not lead to a significant increase in the BBB permeability against intravenously injected EB dye. We conclude that ethanol intake protects the BBB against the effects of hypothermia.     

Education cooperation in the European Union at the threshold of the New Millenium

The principles of ‘double relevance’ and ‘user-friendliness’ are seen as being essential for the implementation of the EU education programmes SOCRATES II and LEONARDO da VINCI II. Against the background of the acquis in EU education cooperation two points are explored: a) the articles of the Treaty are not fully used, and b) the framework set is increasingly proving to be too restrictive. The Luxemburg process and the Bologna conference are the reason for the second point. The opinion is put forward that the exchanges of students and teachers and the information exchange can be further europeanized and, eventually, be organized in permanent European structures. This revised version was published online in July 2006 with corrections to the Cover Date.     

Coexistence of public and private job agencies: Screening with heterogeneous institutions

In response to the analysis of bureaucracies and the finding of inherent inefficiencies, public choice theory argues for an increase in competition by contracting out government services and deregulation. The paper explores the effect of coexisting public and private employment services in a model with private information of the worker about her ability and unobservable effort choice. The employer's use of an efficient unemployment exchange and an efficient private agency may lead to optimal screening with first best contracts. This is due to the assumption that good types of workers lose more human capital than bad types in periods of unemployment or mismatch. In contrast to standard screening contracts, a bad type of worker earns an information rent if the employment exchange is inefficient, but the employer chooses not to use the private agency for good types.     

Lethal child abuse (through the use of physical force) in the German Democratic Republic during the period 1 January 1985 to 2 October 1990. Results of a multicenter study

No reliable data are available on cases of lethal child abuse (by active force) in the area of the former German Democratic Republic. In a multicenter study we therefore examined the police and court records for such cases occurring in the period 1 January 1985 to 2 October 1990 in the entire area of the former German Democratic Republic. RESULTS: The study center received information on 39 cases of lethal child abuse which correspond to approximately 7 cases per year. However, a low percentage of undetected crimes which cannot be determined more precisely has to be taken into consideration. Almost 40% of the victims were younger than 1 year, 73% of the victims showed indications of repeated ill-treatment. The effects caused by using direct blunt forces, against the head in particular, were by far the most frequent causes of death. The male contact person (the victim's father, brother or stepfather as well as the life companion of the child's mother in particular) killed the child in most of the cases. As far as it is known, 37% of the male/female offenders suffered from chronic alcoholism; 32% of the male/female offenders were under the influence of alcohol when the crime happened. 83% of the male/female offenders who were found guilty made a confession shortly after the crime had happened or during the interrogations. Almost all the male/female offenders were sentenced to prison (the duration of the imprisonment varied between one year and for life). Due to the considerably lower section rate compared to the one in the German Democratic Republic, it is to fear that each second fatal child abuse is not detected in the new federal states.     

Fatal child abuse (caused by physical violence) in Germany during 1 January 1985 to 2 October 1990. Results of a multicenter study]

No reliable data are available on cases of lethal child abuse (by active force) in the area of Federal Republic of Germany prior to reunification (the former West Germany). In a multicenter study we therefore examined the police and court records for such cases occurring in the period 1 January 1985 to 2 October 1990 in nearly the entire area of Federal Republic of Germany. RESULTS: The study center received information on 58 cases of lethal child abuse. Extrapolated to all institutes of legal medicine, this corresponds to 62 cases in all of West Germany in the period studied. An approximately equal number of unreported cases should be added to this figure. Including unreported cases, at least 20 cases of lethal child abuse occurred per year; thus only one in every two cases ever came to light. Almost two thirds of the victims were younger than one year old. At autopsy 59% exhibited signs of repeated abuse at autopsy. By far the most common cause of death was direct impact from a blunt object, usually to the head. Mostly, the male person to whom the victim relates most closely (father, stepfather, partner of the mother) has killed the child. Twenty-one of the 74 persons charged saw the charges against them dropped or were acquitted due to lack of evidence; 51 received sentences ranging from one year probation to life. In the remaining two cases the outcome of the trial was unknown. Signs of abuse were readily apparent at autopsy in almost all cases. The high number of unreported cases underscores the need to educate medical students and practicing physicians to be on the look-out for signs of abuse and argues for an increase in the rate of autopsy.     

(Non-)complexity through the eyes of MiFID

The European Commission recently published legislative proposals to reform the Markets In Financial Instruments Directive (MiFID). This note elaborates on the proposed shift in classification of “structured Undertakings for Collective Investment in Transferable Securities (UCITS)”. While MiFID I labeled all UCITS “non-complex”, MiFID II deems all structured UCITS “complex”. We propose a logical and consistent framework to refine this dichotomy and identify a limited number of product types amongst the various kinds of structured investments. The classification is traceable, comprehensible and is proposed as the basis of a “complexity indicator” that surpasses the current generalisation.
