The elevated risk for non-lethal post-separation violence in Canada: a comparison of separated, divorced, and married women

The purpose of the study was to shed light on the potentially differing dynamics of violence against separated and divorced women by their ex-husbands and violence against married women by their current husbands. Using a nationally representative sample of 7,369 heterosexual women from Cycle 13 of Statistics Canada's General Social Survey, available risk markers were examined in the context of a nested ecological framework. Separated women reported nine times the prevalence of violence and divorced women reported about four times the prevalence of violence compared with married women. The strongest predictors of violence against married women, namely, patriarchal domination, sexual jealousy, and possessiveness, were not significant predictors of violence against separated and divorced women. This suggested that post-separation violence is a complex phenomenon the dynamics of which can be affected by much more than domination and ownership.     

Genetic population data of 12 STR loci of the PowerPlex Y system in the state of São Paulo population (Southeast of Brazil)

Allele frequency distributions and population data for 12 Y-chromosomal short tandem repeats (STRs) included in the PowerPlex^®Y Systems (Promega) were obtained for a sample of 200 healthy unrelated males living in São Paulo State (Southeast of Brazil). A total of 192 haplotypes were identified, of which 184 were unique and 8 were found in 2 individuals. The average gene diversity of the 12 Y-STR was 0.6746 and the haplotype diversity was 0.9996. Pairwise analysis confirmed that our population is more similar with the Italy, North Portugal and Spain, being more distant of the Japan.     

Justice in Our World and in that of Others: Belief in a Just World and Reactions to Victims

Framed by the Belief in a Just World theory (BJW; Lerner, M. J. (1980). Belief in a just world: A fundamental delusion. New York: Plenum Publishing Corporation), this article presents two studies that analyze people’s reactions to the suffering of victims belonging to an ingroup and an outgroup. In Study 1, participants viewed a videotaped film containing the victimization story. The victim was presented as a non-categorized, ingroup or outgroup (Gypsy) victim. Threat to BJW was measured using the modified Stroop task developed by Hafer (J Pers Soc Psychol 79:165–173, 2000). In the second study, a non-victimization story was introduced and a 2 (victim, non-victim) × 2 (ingroup, outgroup) between-subjects design was used. Both studies show that the ingroup victim is more threatening to the BJW than the outgroup victim. The expected secondary victimization of the ingroup victim was only obtained in the second study when a non-obtrusive derogation measure was used.

The Karimojong from Uganda: Genetic characterization using an X-STR decaplex system

The Karimojong, an African group from the Karamoja region of Northeast Uganda, were genetically analysed using a decaplex system for X chromosome short tandem repeats (X-STRs). A total of 255 individuals (117 males and 138 females) were genotyped for the following loci: DXS8378, DXS9898, DXS7133, GATA31E08, GATA172D05, DXS7423, DXS6809, DXS7132, DXS9902 and DXS6789. Allele frequencies and parameters for forensic evaluation were calculated for each STR. No association was found between any pairs of loci studied. DXS6789 was the most polymorphic marker in this sample, followed by DXS6809, with gene diversities of 84.79% and 83.94%, respectively. The less discriminating locus observed was DXS7133, with a gene diversity of 39.79%. High overall values of power of discrimination were obtained for female (1 in 1.8 × 10¹⁰) and male samples (1 in 1.6 × 10⁶), as well as high power of exclusion in father/mother/daughter trios (99.9997%), in father daughter duos (99.9862%) and in half sisters with same father (99.0331%). These results confirm the potential of this 10-plex in parentage testing and in human identification.     

Influence of the luminol chemiluminescence reaction on the confirmatory tests for the detection and characterization of bloodstains in forensic analysis

Preliminary tests for the detection of stains at crime scenes aim to focus the police work making them more efficient in the combat of criminality. The application of the luminol chemiluminescence reaction (3-aminoftalhidrazida) in presumptive tests for the detection of bloodstains is known for more than 40 years in forensic science. This reaction is based on the emission of light through the chemical reaction of luminol mixed with hydrogen peroxide and a hydroxide in the presence of a catalytic molecule (iron from the hemoglobin) (Laux [1]).This work evaluates the luminol interference and its effect on subsequent serological and DNA testing. Samples prepared with blood and different concentrations of luminol solution containing luminol, peroxide of hydrogen and sodium carbonate, were analyzed. Additionally, samples of serial dilutions of standard DNA mixed with luminol solution were also analyzed. Although presumptive tests with luminol do not establish the characterization and identification of stains at crime scenes, preliminary results indicated that it is suitable for the detection of invisible bloodstains for forensic analysis, with few detrimental effects on the serological tests and subsequent DNA recovery and typing.     

Property and the cloud

Data is a modern form of wealth in the digital world, and massive amounts of data circulate in cloud environments. While this enormously facilitates the sharing of information, both for personal and professional purposes, it also introduces some critical problems concerning the ownership of the information. Data is an intangible good that is stored in large data warehouses, where the hardware architectures and software programs running the cloud services coexist with the data of many users. This context calls for a twofold protection: on one side, the cloud is made up of hardware and software that constitute the business assets of the service provider (property of the cloud); on the other side, there is a definite need to ensure that users retain control over their data (property in the cloud). The law grants protection to both sides under several perspectives, but the result is a complex mix of interwoven regimes, further complicated by the intrinsically international nature of cloud computing that clashes with the typical diversity of national laws. As the business model based on cloud computing grows, public bodies, and in particular the European Union, are striving to find solutions to properly regulate the future economy, either by introducing new laws, or by finding the best ways to apply existing principles.     

Y-chromosome STR haplotypes in two population samples: Azores Islands and Central Portugal

The Y-chromosome haplotypes defined by nine STRs (DYS19, DYS385, DYS389I, DYS389II, DYS390, DYS391, DYS392 and DYS393) were studied in 207 unrelated individuals from Central Portugal and 63 from Azores Islands. The most common haplotype in Central Portugal was shared by 3.4% of the males, while 160 haplotypes were unique. In Azores Islands the most common haplotype was shared by 6.4% of the males, while 40 haplotypes were unique. The values of haplotype diversity were 0.993 for Central Portugal and 0.976 for Azores Islands.     

Importance of information in forensic toxicology.

Information in forensic toxicology plays a very important role. The forensic pathologist usually seeks toxicologic analyses on basis of the information available at the time of the medicolegal autopsy. Such information may be obtained from different sources: hospitals, authorities, relatives, friends, or neighbors of the deceased and, obviously, macroscopic findings at the time of the autopsy. In order to evaluate the relative importance of these different sources of information, the authors have studied, retrospectively, results of 580 postmortem examinations performed at the Institute of Legal Medicine of Lisbon, wherein toxicologic analyses had been requested. These cases pertain to the years 1987 and 1988, but do not include alcohol determination in the blood in cases of traffic accidents. In 274 (47.4%) of the 580 cases, there were positive findings while in the remaining 306 (52.6%) findings were negative. In cases with positive findings, circumstances and factors, which may have influenced the pathologist's decision to request toxicologic analysis, are discussed. In more than half the cases, hospital information was the decisive factor, while in approximately 25% of the cases, autopsy findings were the justification. In contrast, it is worth mentioning that in approximately 45% of the cases with analytical negative results, requests were made, in cases of blank autopsies, for toxicologic analyses in order to exclude the possibility of poisoning. It is interesting to note that in the same proportion requests were justified on grounds of hospital information. Some of the factors that may explain this apparent discrepancy are discussed. Finally, the relevance of background information is emphasized at the level of the interpretation of analytical results, whether positive or negative.(ABSTRACT TRUNCATED AT 250 WORDS)
