Scanning electron microscopy: application in the identification of diatoms in cases of drowning.

A simple and rapid method is described for processing organ and water samples for the identification of diatoms so that they can be studied and recorded for taxonomic and diagnostic purposes. Samples are treated with concentrated nitric acid; the fluid obtained is centrifuged, and its sediment is dried, coated, and examined under the scanning electron microscope. The method does not alter the morphology of diatoms and allows the study of freshwater and seawater species present in the organs of bodies found in the water, making possible the diagnosis of drowning under specific conditions.     

Trade union behaviour and inter-regional variations in unemployment rates

An important problem in the political economy of the UK is that the disparity of unemployment rates across its regions is much more marked than the corresponding dispersion of wage rates. One possibility is that this is due to the attitude of trade unions to their members in different regions. If unions wish to preserve parity between members in different regions then they will value wage equality between regions over and above wage levels. This may then persuade them to overlook inter-regional productivity differences in setting wages. The price that low-efficiency regions will then pay for this desire for wage equality is higher unemployment rates.Much of the research for this paper was carried out while the author was visiting the Trade Union Economics Research Institute (FIEF), Stockholm in 1989.

Sexual harassment in student residences: A response to DeKeseredy and Kelly's study

Research data from a recent study of sexual harassment in single student residences are provided as confirmation of DeKeseredy and Kelly's national study. The implications of data confirming the consistency of gender differences in attitudes towards and perceptions of unwanted sexual experiences are discussed. Future research in sexual harassment should focus on evaluating preventive education programmes and on operationalizing contextual factors that support sexual harassment.     

The supplementary signs of strangulation asphyxia]

Analyzes the results of forensic medical examinations of the corpses after hanging. The findings were as follows: two strangulation grooves are seen on the corpse's neck after hanging, that are similar to the grooves seen after strangulation with a loop and subsequent hanging of a corpse; the presence of bruises on the neck, along with the strangulation grooves, is indicative of a strangulation made by the hands, whereas half-moon shaped bruises may be self-inflicted during hanging.     

The use of phosphate buffered saline for the recovery of cells and spermatozoa from swabs.

In the forensic science laboratory, the recovery of spermatozoa from vaginal swabs, or vaginal cells from penile swabs, can help determine if sexual intercourse may have taken place. There are several methods used to recover spermatozoa and cells from the swabs before visualisation on a microscope slide and most of these methods use water. Phosphate buffered saline (PBS) is a non-toxic solution used in many biological laboratories. Unlike water, PBS prevents cells rupturing or shrivelling up due to osmosis. This study demonstrates that PBS can be used for the extraction of spermatozoa and cells from swabs and that PBS does not affect subsequent DNA profiling.     

The establishment of the features of the blade of a stabbing-cutting weapon by the damages to human skin and to tricot clothing]

Presents forensic medical characteristics of the specific features of stabbed and cut injuries of human skin and jersey. Suggests a complex of signs that will help determine some structural parameters of a knife blade and the conditions of its interaction with the injured site of human body.     

Intimate Partner Violence in Extremely Poor Women: Longitudinal Patterns and Risk Markers

Despite high revalence rates of intimate partner violence in the lives of extremely poor women with dependent children, few studies have investigated the patterns of violence that occur over time, and the characteristics of women that serve as risk markers for partner violence. This paper describes patterns of domestic violence longitudinally and uses multivariate analyses to delineate childhood and adult risk markers for recent intimate partner violence in this population of women. Analyses draw upon a sample of 436 homeless and extremely poor housed mothers receiving welfare, in a mid-sized city in Massachusetts with a large Hispanic population of Puerto Rican descent and relatively fewer Blacks. We found that among women with complete longitudinal data (N=280), almost two-thirds experienced intimate partner violence at some point during their adult life by the end of study follow-up, and that the abuse before and after the baseline interview was episodic and limited over time. To examine the role of individual women's factors, while controlling for partner characteristics, we used baseline data on women who had been partnered during the past year (N=336). Among childhood predictors, we found that sexual molestation contributed most significantly to adult intimate partner violence that occurred during the past year prior to the baseline interview. Adult risk markers included inadequate emotional support from non-professionals, poor self-esteem, and a partner with substance abuse problems. Having a partner with poor work history was another independent predictor of recent abuse. Ethnicity did not significantly predict whether women were abused or not during the past year, contrary to other findings reported in the literature.
