Petechiae in hanging: a retrospective study of contributing variables

Petechiae, one of the classic signs of asphyxia, are thought to be more frequently observed in cases of hanging where part of the body is supporting the victim's weight, ie, cases of incomplete hanging. However, there is very little evidence-based medicine to support this claim. The present study is intended to evaluate the relationship between petechiae and the type of hanging (complete vs. incomplete). Furthermore, several other variables were analyzed to determine if they contribute significantly to the presence of petechiae. An 8.5-year retrospective study of 206 cases of death by hanging reviewed autopsy reports for the presence of petechiae. For each case, the following information was also compiled: gender and age, height and weight, body mass index, the type of hanging (complete or incomplete suspension), the type of ligature used (narrow or wide), and whether or not the victim had received cardiopulmonary resuscitation maneuvers. Statistical analysis revealed that the incidence was higher among incomplete hanging victims compared with cases of complete suspension and that the incidence of petechiae varied inversely with the height of the victims. The other factors were not shown to contribute significantly to the presence of petechiae.     

Pathogen detection using a liquid array technology

Abstract: Low concentrations of microbial pathogens in pure and mixed samples were detected using a bead‐based, liquid array technology. A 20‐bp sequence in the 23S rRNA gene, rrl, was amplified in four microorganisms: Bacillus cereus, Escherichia coli, Salmonella enterica and Staphylococcus aureus. PCR products were positively identified with the Luminex^® 100? system. The system could detect very low amounts of DNA and the instrument response was proportional to the input concentration. The lower limit of detection (LLD) was determined to be 0.5 ng for B. cereus and E. coli and 2 ng for S. enterica. The LLD for S. aureus was not determined as the instrument response was still above the threshold when quantities of DNA as low as 0.25 ng were used. The platform positively identified organisms present in mixed samples even when the minor component was overshadowed by a 10‐fold excess of the major component.     

THE MIRAGE OF MERIT

This paper takes a hard look at merit and the ideal academic, twin concepts that have been accorded short shrift by the scholarly literature. For the most authoritative positions, the ideal displays all the hallmarks of Benchmark Man. Despite the ostensible ‘feminisation’ of the academy, the liberal myth that merit is stable, objective and calculable lingers on. As a counterpoint to the feminisation thesis, it is argued that a re-masculinisation of the academy is occurring as a result of the transformation of higher education wrought by the new knowledge economy. In response, the ideal academic has become a ‘technopreneur’—a scientific researcher with business acumen who produces academic capitalism. This new ideal academic evinces a distinctly masculinist hue in contrast to the less-than-ideal academic—the humanities or social science teacher with large classes, who is more likely to be both casualised and feminised.     

Homonormative Collusions and the Subject of Rights: Reading <Emphasis Type="Italic">Terrorist Assemblages</Emphasis>

This essay provides an analytic review of Jasbir Puar’s book, Terrorist Assemblages (2007), situating her discussion and analysis of “homonationalism” within the context of recent developments in queer theory in the USA, and specifically, critiques of queer liberalism and gay imperialism; racial analyses of hetero- and homo-normative formations; and challenges to identity politics and representational frameworks that dominate LGBT studies. It takes up Puar’s interest in finding new methods and ‘reading’ practices to track certain shifts in LGBT politics and to account for alignments between (white) queerness and normative, nationalist and imperial interests. Engaging with and expanding on her analysis, this paper discusses the challenge that Terrorist Assemblage poses to the identity categories that undergird human rights campaigns, and addresses the racist and nationalist sentiments that she locates within them.
