Sex determination of human blood micro-stains and single hairs using specific DNA amplification with polymerase chain reaction

Amplification of Y chromosome specific DNA in vitro enables a rapid and reliable sex determination of human minute traces such as blood stains and hairs. In presence of male DNA a band of 154 bp is visualized by agarose gel electrophoresis after amplification, this band is lacking in case of female DNA alone. Amplification of a sex independent DNA locus (such as a fragment from the alcohol dehydrogenase gene) generates identical reaction products for both sexes. This shows that the absence of a band is not due to the lack of trace DNA. It is possible to perform this technique with as little as 0.5 microliters of blood or with a single hair.     

A case of suicidal hanging in an automobile

A case of suicidal hanging inside an automobile is presented. To our knowledge, hanging has not been previously reported as a cause of death in a motor vehicle driver. The causes of death in automobile-related suicides are discussed.     

Family violence and depressive symptomatology among incarcerated women

This study examines the potential association between witnessing parental violence as a child and later adult depressive symptomatology within a population that has received limited attention in the scientific literature, namely, incarcerated women. The Conflict Tactics Scale and the Center for Epidemiological Studies Depression Scale were administered to 60 women incarcerated in a maximum security prison in North Carolina. A majority of the women reported that they had witnessed verbally aggressive or physically violent interactions among the adult members in their families. Seventy percent of these women suffered from clinically relevant levels of depressive symptomatology. Stepwise multiple linear regression analysis revealed that increasing levels of reasoning conflict resolution strategies used in the women's families of origin were associated with decreasing levels of depressive symptomatology of the women, whereas increasing levels of physically violent conflict resolution strategies were associated with increasing levels of depressive symptomatology.     

The Fox and the Hunters: How IC Technologies Change the Crime Race

The article deals with the impact of new technologies on crime. Specifically, the analysis develops two aspects: an analysis of how new technologies are reshaping criminal typologies, dynamics and trends; and an analysis of the most important challenges that legislation, law enforcement and science have to face in order to prevent and combat Information and Communication Technologies (ICT)-related crime. From the methodological perspective, each section opens with a specific question and develops by trying to find a suitable answer. The paper starts by analysing what impact new technologies have on society and crime. It continues by examining how criminal patterns are changing (How does ICT facilitate the commission of new and traditional crimes?) and who these criminals are (Are criminals really going cyber?). It ends by focusing on the other side, on how crime is prevented and combated (How are technologies reshaping the approach and the fight against crime at legal, law enforcement and scientific levels?). The analysis and the results achieved show that new technologies are valuable means in the hand of both criminals and institutions involved in the fight against crime. There is thus an urgent need to improve knowledge about the phenomena, and develop new paradigms and theories together with best practices.
