Self-disclosure, depression, anxiety, and suicidal behavior in adolescent psychiatric inpatients

The objectives of this paper were to examine the personality variable of self-disclosure, or the tendency to share feelings with others, and its relationship to depression, anxiety, and suicidal behavior in adolescent psychiatric inpatients. Of the 87 adolescents who were assessed, 53 had made a suicide attempt and 34 had never shown any suicidal behavior during their lifetime. There was a significant relationship between suicidality and low levels of self-disclosure, which appears to be mediated by anxiety and depression. This sharing difficulty was most significantly marked between the adolescent and his/her family and seemed to be mediated by feelings of depression and anxiety.     

Suicide to harass others: clues from mythology to understanding suicide bombing attacks

Suicide by revenge, the Samsonic suicide, and the suicide by devotio, all described in classical mythology and also reported in the ethnographic literature, belong to the same class of suicidal behaviors as kamikaze suicide and the suicide bombing attack: suicide to harass and burden others or suicide with a hostile intent. The lack of a social dimension to share in a positive manner may lead an individual to integrate him/herself in another social structure, e.g., a military organization, which allows the individual to express his/her desires and personal identity only by destroying others and themselves. The dynamics of these forms of suicide are also likely to work in other displays of life-threatening behavior, such as family annihilation, mass murder, and spree killing. A more thorough investigation of the dynamics operating in suicide bombing attacks could, therefore, contribute to preventative strategies against violence at large.     

The forensic analysis of soils and sediment taken from the cast of a footprint

The routine production of a cast of a shoe-print taken in soil provides information other than shoe size and gait. Material adhering to the surface of the cast represents the preservation of the moment of footprint impression. The analysis of the interface between the cast and soil is therefore a potentially lucrative source of information for forensic reconstruction. These principles are demonstrated with reference to a murder case which took place in the English Midlands. The cast of a footprint provided evidence of a two-way transfer of material between the sole of a boot and the soil of a recently ploughed field. Lumps of soil, which had dried on a boot, were deposited on the field as the footprints were made. Pollen analysis of these lumps of soil indicated that the perpetrator of the imprint had been standing recently in a nearby stream. Fibre analysis together with physical and chemical characteristics of the soil suggested a provenance for contamination of this mud prior to deposition of the footprint. Carbon/nitrogen ratios of the water taken from the cast showed that distilled water had been used thus excluding the possibility of contamination of the boot-soil interface. It was possible to reconstruct three phases of previous activity of the wearer of the boot prior to leaving the footprint in the field after the murder had taken place. This analysis shows the power of integrating different independent techniques in the analysis of hitherto unrecognised forensic materials.     

Racemization of aspartic acid from human dentin in the estimation of chronological age

The estimation of chronological age in cadavers, human remains and in living human beings by various methods is discussed. These methods, which are based on the age dependent non-enzymatic changes of l-form amino acids to d-form amino acids, mainly aspartic acid, are among the most reliable and accurate methods to date. Most of these methods use gas chromatography (GC). In this review, results of aspartic acid racemization in dentin at different targets are discussed. In addition, pre-considerations and guidelines are given for the selection of dentin from teeth. A pilot project was run to evaluate the efficiency of high performance liquid chromatography (HPLC) coupled with fluorescence detection. New buffer conditions were found to obtain stable derivatives of aspartic acid enantiomers for the estimation of racemization.     

Age estimation of unaccompanied minors. Part I. General considerations

In recent years many countries have experienced a sharp increase in the demand for forensic age estimates of unaccompanied minors. In many countries the age thresholds of relevance to criminal prosecution lie between 16 and 22 years. In line with recommendations issued by the Study Group on Forensic Age Diagnostics, for determining the age of live subjects a forensic age estimate should combine the results of a physical examination, an X-ray of the hand and a dental examination which records dentition status and evaluates an orthopantomogram. To assess the age of persons who are assumed to be at least 18 years old, an additional radiographic or CT examination of the collar bones is recommended. Forensic age estimates should take account of the ethnic origin and socio-economic status of the person under examination.
