The "utility" principle within the scope of forensic determination of blood kinship using serostatistics

A "realistic" prior probability is always based on case experience (Akten-a-priori). In serological opinions pertaining to parentage, the realistic prior probability is only one piece of information in the whole body of evidence before the judge and does not have any special significance per se. There is no such thing as a "neutral" prior probability. It either implies "ignorance," in which case it cannot be "information," or it must be taken in connection with the utility principle, in which case it is not a "probability." The utility principle is defined in law and cannot be expressed in figures. The utility principle takes effect only when the judge reaches a decision (on the basis of all the evidence before him). It determines the relative importance of the participant's objects of legal protection which are at issue in the case. The expert is bound to apply a neutral utility component, i.e., in a two-hypothesis case (the normal situation) the significance of both the null and the counter hypothesis must carry the same weight. A null and/or a counter hypothesis can combine several single hypotheses; the mean value of their frequencies is taken. As a rule, one should avoid using a "prior case probability" ("Akten-a-priori") when calculating a W value. An "expectation of error" should be as realistic as possible and hence be obtained using a "prior case probability."     

Preliminary test with chlorindazone DS for zinc in Sintox residue

So-called exit bags are voluminous, transparent plastic bags, each with a collar to go round the neck, and a Velcro fastening. In conjunction with the consumption of sleeping pills, the bags are recommended as an aid to commit suicide by organizations in favour of "humane death". It is reported on four such suicides by elderly people between 79 and 87 years of age. In two of these cases, there was assistance in committing suicide, one corresponding to a suicide protocol from the Swiss organization for euthanasia, EXIT. In two cases, detailed instructions for committing suicide were found. The morphological findings were not very specific in any of the cases. If the plastic bags are removed by a third party, this type of suicide may remain undetected even after performance of an autopsy. Exit bags tend to be used by older people with either real or feared life-threatening illnesses, in suicides which have usually been planned for some time. From the criminological point of view, the possible active participation of other persons in pulling the covering over the head can often not be proved. Assisting a suicide, in the sense of giving instructions on how to accomplish it, is not punishable in German law.     

Detection of ketosis in vitreous at autopsy after embalming

Ketosis occurs in ketoacidosis or malnourishment. When either is suspected in relation to a death, it may be important to analyze for ketosis at autopsy. We encountered a case where starvation was suspected in a deceased nursing home resident, where the body had been embalmed prior to autopsy. Gas chromatography (GC) was unable to separate acetone from formaldehyde, a component of embalming fluid. The Acetest is a simple test that can detect acetone and acetoacetate in body fluids. We validated the Acetest with GC on vitreous. The Acetest and GC were consistent except at very low levels of acetone or acetoacetate. The sensitivity of the Acetest for acetoacetate in vitreous was 10 mg/dL, consistent with early starvation. Significant interference from embalming fluid did not occur. The Acetest was negative in the described case. The Acetest is a simple and useful test for the detection of ketosis in embalmed autopsies.     

Psychological and psychosocial interventions after attempted suicide: an overview of treatment studies

A literature search was conducted to collect randomized controlled studies evaluating the outcome of psychological and psychosocial interventions after attempted suicide and deliberate self-harm. Twenty-five studies meeting the inclusion criteria were identified. The studies are grouped according to the psychological approach chosen for the intervention. They are discussed with regard to both the various therapeutic strategies and models used, and the repetition of self-harming behavior as the main outcome.     

Deliberation in large juries with diverse preferences

This paper considers a game in which imperfectly informed jurors who differ in their thresholds of reasonable doubt must decide whether to convict or acquit a defendant. Jurors deliberate prior to voting on the fate of the defendant, and the defendant is convicted only if all jurors vote to convict. Although it has been established that full information revelation is impossible when jurors have sufficiently heterogeneous preferences, this paper demonstrates that if each juror shares preferences with a small fraction of the other jurors, it is possible to obtain enough information revelation so that the correct decision is made with probability arbitrarily close to one in large juries.     

Previous judicial detection and paedophilic sexual interest partially predict psychological distress in a non-forensic sample of help-seeking men feeling inclined to sexually offend against children

Little is known about overall psychological distress in paedophiles who are not formally involved with the criminal justice system. Since knowledge in this context could help to optimise intervention efforts, this study aimed to examine the association between distress as measured with the Brief Symptom Inventory (BSI) and preference- and offence-related variables in a sample of N?=?455 men self-reporting sexual interest in children, of whom 402 were diagnosed as paedophiles. Results showed that 59% reported clinically relevant levels of distress, with paedophiles being significantly more distressed than teleiophiles. A regression analysis revealed that a paedophilic preference and prior detection were relevant predictors for distress. However, past offending behaviour had no impact and the major part of variance could not be explained. The results suggest that paedophilia is associated with distress, but other factors influence whether a paedophilic man is distressed on a clinically significant level.
