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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

We consider the problem of drawing inferences within a legal framework when a person is a suspect for two separate offences. Although we are primarily concerned with scientific evidence the issue inevitably arises as to how that evidence interacts with other, non-scientific evidence. We show that, in this particular context, the evidence can be conveniently classified into three categories that concern, respectively: the first crime only; the second crime only; and evidence that relates to similarities between the two crimes. Two case examples are considered and we consider DNA, fibres and eyewitness evidence. These are viewed from the perspective of a prosecutor who has to decide whether or not to charge a suspect with one or both crimes. Graphical sensivity analyses are presented which have features that are not intuitively obvious.  相似文献

California is now in its 11th year of mandatory child custody mediation, with a current yearly case volume statewide estimated at 65,494. This article profiles the variations in programs and mediation styles in 56 of the state's 58 Superior Courts. Two research studies provide the basis for the information on program structures, case activity, procedures, agreement formats, recommendations, facilities, security, and fees.  相似文献

In this article a practical case is described when gunshot directions and position of a victim's body at the moment of each shot were determined by natural simulation using an LG-78 laser (made in the form of a gun).  相似文献

The analysis of naphthenic acid revealed that they may be used for tin detection in the cadaveric material due to their high complex-forming ability. Method of extraction-atomic absorption tin determination in human organs was developed on the basis of naphthenic acid use. Modified method which differs from the common one by higher sensitivity and selectivity is presented.  相似文献
