Higher failures of amelogenin sex test in an Indian population group

The human sex test in forensic multiplexes is based on the amelogenin gene on both the X and Y chromosomes commonly used in sex genotyping. In this study of 338 male individuals in a Malaysian population comprising Malays, Chinese and Indians, using the AmpFlSTR Profiler Plus kit, the amelogenin test gave a significant proportion of null alleles in the Indian ethnic group (3.6% frequency) and 0.88% frequency in the Malay ethnic group due to a deletion of the gene on the Y chromosome. This sex test also failed in a forensic casework sample. Failure of the amelogenin test highlights the need for more reliable sex determination than is offered by the amelogenin locus in the Malay and Indian populations. The gender of the Indian-Malay amelogenin nulls was confirmed by the presence of three Y-STR alleles (DYS438, DYS390 and DYS439). For the Indian ethnic group, one of the Y-STR forms a stable haplotype with the amelogenin null. The amelogenin-deletion individuals also showed a null with a male-specific minisatellite MSY1, indicating that a very large deletion was involved that included the amelogenin and the MSY1 loci on the short arm of the Y chromosomes (Yp).

Identification of forensically important Chrysomya (Diptera: Calliphoridae) species using the second ribosomal internal transcribed spacer (ITS2)

The identification of forensically important blowflies of the genus Chrysomya (Diptera: Calliphoridae) may be hampered by their close morphological similarities, especially as immatures. In contrast to most previous studies, the utility of a nuclear rather than mitochondrial genetic marker was investigated to solve this problem. The second internal transcribed spacer (ITS2) of ribosomal DNA (rDNA) was amplified and sequenced from all nine Chrysomya species known from Australia. Difficulties encountered with direct sequencing of ITS2 for Chrysomya flavifrons necessitated cloning prior to sequencing for this species, which revealed a low level (0-0.23%) of intraindividual variation. Five restriction enzymes (DraI, BsaXI, BciVI, AseI and HinfI) were identified that were able to differentiate most members of the genus by polymerase chain reaction (PCR) restriction fragment length polymorphism (PCR-RFLP). The PCR-RFLP analysis revealed characteristic restriction profiles for all species except the closely related species pairs Chrysomya latifrons+Chrysomya semimetallica and Chrysomya incisuralis+Chrysomya rufifacies. Ch. incisuralis and Ch. rufifacies were able to be separated using the size differences resulting from amplification of the entire ITS region. The lack of intraspecific ITS2 sequence variation among eight Ch. incisuralis specimens was verified by the identical restriction profiles generated from these specimens. A DNA-based approach, such as PCR-RFLP, has the capacity to be useful for the identification of forensic entomological evidence in cases where morphological characters are unreliable.     

Examining the role of pornography and rape supportive cognitions in lone and multiple perpetrator rape proclivity

ABSTRACT

Since a substantial proportion of sexual offenders are not apprehended, researchers have introduced methods to test the propensity to sexually offend among the general public. Proclivity measures assess self-reported sexual interest in lone and multiple perpetrator sexual offending or rape (MPR), and can examine students and community members who indicate a proclivity to sexually offend. This study examines the role of pornography use and rape supportive cognitions to influence proclivity. Anonymous online data was collected from 295 male university students to assess the role of rape supportive cognitions and pornography use in predicting lone and MPR proclivity. Only rape supportive cognitions predicted scores on lone and MPR proclivity measures.     

Leadership in multiple perpetrator stranger rape

Sexual offences by multiple perpetrators are more violent and involve more severe forms of sexual violation than those perpetrated by a lone offender. Often a clear leader exists within these groups. Questions have been raised as to the relative risk of reoffending and the potentially differing criminogenic needs of leaders and followers. However, a recent study comparing leaders and followers in juvenile multiple perpetrator rapes (t'Hart-Kerkhoffs et al., 2011) failed to find some of the expected differences. It was proposed that this might be due, in part, to the way leaders and followers were classified in the study. Before work can progress in this area, it is important to devise reliable and valid means of identifying leaders and followers in multiple perpetrator rape. This article reports on a study which investigated the utility of two different methods of identifying leadership. The Scale of Influence (Porter & Alison, 2001) was applied to a sample of 256 offenders responsible for 95 multiple perpetrator rapes from the United Kingdom. Following this, the relative number of directives uttered by offenders was used to designate leadership. In 66% of the offences sampled, a leader was designated using the number of directives uttered compared with 80% when using the Scale of Influence. When combining both measures to form a composite measure of leadership, this percentage increased to 89%. Classifications of offenders as leaders, followers, and neither, according to the Scale of Influence, the count of directives, and the composite measure, were compared with classifications made by a practitioner to assess their concordance. The composite measure showed the greatest agreement with practitioner opinion. These findings suggest that the Scale of Influence could be developed to take account of other ways that leadership is displayed during multiple perpetrator rapes.     

Learning By Doing: The Long-Term Impact of Experiential Learning Programs on Student Success

Abstract

As the advisers for the Model United Nations and Judicial Internship programs at our university, we have witnessed first-hand the benefits of simulations and experiential learning. Specifically, students are able to apply knowledge from other classes to real-world situations, all while honing their writing skills and communication skills, as well as their ability to analyze and synthesize information—skills that are critical to success in a wide variety of careers. This practical experience also gives students confidence as they prepare for and make decisions about their future career paths. While we have anecdotal evidence suggesting that these programs contribute to student success, we use survey data from former students to assess formally the longer-term impact of participating in these programs. We find that experiential learning programs contribute to student success by improving time to graduation and increasing the likelihood of attending graduate school or law school and/or finding employment after graduation. In addition, the students’ own assessments indicate that these programs instill numerous practical skills and provide insights that help prepare students for success in their future careers.     

Anna Kavan’s Ice and Alan Burns’ Europe After the Rain: Repetition with a Difference

Abstract

While Anna Kavan’s work has been largely ignored by critics, the responses of those who have noticed her have been dominated by two assertions. First, many of those wishing to assert her importance and power have seen her work as sui generis, the result of her isolation from the surrounding literary culture. Second, numerous feminist critics have seen her work as reproducing the worst effects of patriarchal domination. This article, through a reading of Kavan’s final novel, Ice (1967), challenges both of these assessments of Kavan. It suggests that, if we notice and try to account for the similarities between Ice and a novel published two years earlier, Alan Burns’ Europe After the Rain (1965), Kavan’s novel can be read as challenging patriarchal domination through a bold and innovative reworking of the reader’s ‘suspension of disbelief’.
