Transgressive sporting bodies - A theoretical and critical dicourse analysis of the representation of Caster Semenya in Swiss print media

A debate about Caster Semenya's female sex began shortly after the South African runner won gold in the women’s 800m final at the 2009 Athletic World Championships held in Berlin. Her victory was disputed through questions about her right to compete as a ‘woman’, with the International Association of Athletics Federation (IAAF) announcing she would be required to undergo a gender verification test before her victory could be confirmed. Using the theoretical frame of social constructionism (Berger & Luckmann), poststructuralism (Foucault), gender- and postcolonial theories (Butler; Hall; Spivak) and the methodology of critical discourse analysis (Jaeger), the paper explores the way the possible intersexuality of Caster Semenya was contextualised in mainstream Swiss German-language print media. The analyses will firstly look at the way in which Caster Semenya was constructed as a ʻfallen hero’ and stigmatised as a double-dealer and unacceptable deviant body. The rumours amongst athletes and commentators became news in the media, which focused on descriptions of her habitus, her muscular body and her deep voice. Through theoretical discussion the paper argues that the media response to Caster Semenya exemplifies Butler’s claim that the discursive framework of gender constructs and naturalises sex. A key question is therefore whether the designation of deviant bodies to a ʻfield of deformation’ (Butler) works to pluralise the field of gender, or rather, as Butler suggests, it tends that those bodies might call into questions. The final part of the paper discusses how gender, ethnicity and sexuality combine to constitute the black female sporting body as a spectacle of otherness. It is evident that this otherness is made manifest through the function of those bodies as a site of transgression, as the boundary between male and female, and often as the boundary between culture and nature (Hall). Using the example of the controversy surrounding Caster Semenya, this paper aims to demonstrate how the post/colonial white female body is reproduced by western norms of gender, sexuality, beauty and sporting behaviour, in the sense of a feminine sporting genderperformance. The media controversy will be also read through the lens of the globalisation of certain ideas of normative bodies, sex, ethnicity and gender and the challenge of changing stereotypes through transgression.

Entwicklung einer PCR zum Nachweis der EAV-Infektion

The goal of this work was the development of suitable (real-time) RT-PCR techniques for fast and sensitive diagnosis of EAV and for molecular-epidemiological characterisation of viral strains, as an alternative to virus isolation. To this purpose two conventional RT-PCR methods and one real-time RT-PCR were adapted to detect the broadest possible spectrum of viral strains. Several dilutions with Bucyrus strain showed a 100-fold higher sensitivity of real-time RT-PCR and heminested RT-PCR compared to simple RT-PCR. Making use of 11 cell culture supernatants of different EAV isolates and 7 semen samples of positive stallions, the suitability of the techniques could be shown. Phylogenetic analysis of sequences of the newly analysed samples compared with known sequences indicated that more EAV-lineages exist than presently described.

Genetic markers for stallion fertility - lessons from humans and mice

Our knowledge on the many aspects of mammalian reproduction in general and equine reproduction in particular has greatly increased during the last 15 years. Advances in the understanding of the physiology, cell biology, and biochemistry of reproduction have facilitated genetic analyses of fertility. Currently, there are more than 200 genes known that are involved in the production of fertile sperm cells. The completion of a number of mammalian genome projects will aid in the investigation of these genes in different species. Great progress has been made in the understanding of genetic aberrations that lead to male infertility. Additionally, the first genetic mechanisms are being discovered that contribute to the quantitative variation of fertility traits in fertile male animals. As artificial insemination (AI) represents a widespread technology in horse breeding, semen quality traits may eventually become an additional selection criterion for breeding stallions. Current research activities try to identify genetic markers that correlate to these semen quality traits. Here, we will review the current state of genetic research in male fertility and offer some perspectives for future research in horses.

Potential Impact of Sexual Transmission on Ebola Virus Epidemiology: Sierra Leone as a Case Study.

BACKGROUND Sexual transmission of Ebola virus disease (EVD) 6 months after onset of symptoms has been recently documented, and Ebola virus RNA has been detected in semen of survivors up to 9 months after onset of symptoms. As countries affected by the 2013-2015 epidemic in West Africa, by far the largest to date, are declared free of Ebola virus disease (EVD), it remains unclear what threat is posed by rare sexual transmission events that could arise from survivors. METHODOLOGY/PRINCIPAL FINDINGS We devised a compartmental mathematical model that includes sexual transmission from convalescent survivors: a SEICR (susceptible-exposed-infectious-convalescent-recovered) transmission model. We fitted the model to weekly incidence of EVD cases from the 2014-2015 epidemic in Sierra Leone. Sensitivity analyses and Monte Carlo simulations showed that a 0.1% per sex act transmission probability and a 3-month convalescent period (the two key unknown parameters of sexual transmission) create very few additional cases, but would extend the epidemic by 83 days [95% CI: 68-98 days] (p < 0.0001) on average. Strikingly, a 6-month convalescent period extended the average epidemic by 540 days (95% CI: 508-572 days), doubling the current length, despite an insignificant rise in the number of new cases generated. CONCLUSIONS/SIGNIFICANCE Our results show that reductions in the per sex act transmission probability via abstinence and condom use should reduce the number of sporadic sexual transmission events, but will not significantly reduce the epidemic size and may only minimally shorten the length of time the public health community must maintain response preparedness. While the number of infectious survivors is expected to greatly decline over the coming months, our results show that transmission events may still be expected for quite some time as each event results in a new potential cluster of non-sexual transmission. Precise measurement of the convalescent period is thus important for planning ongoing surveillance efforts.

Lethal chondrodysplasia in a family of Holstein cattle is associated with a de novo splice site variant of COL2A1

Background Lethal chondrodysplasia (bulldog syndrome) is a well-known congenital syndrome in cattle and occurs sporadically in many breeds. In 2015, it was noticed that about 12 % of the offspring of the phenotypically normal Danish Holstein sire VH Cadiz Captivo showed chondrodysplasia resembling previously reported bulldog calves. Pedigree analysis of affected calves did not display obvious inbreeding to a common ancestor, suggesting the causative allele was not a rare recessive. The normal phenotype of the sire suggested a dominant inheritance with incomplete penetrance or a mosaic mutation. Results Three malformed calves were examined by necropsy, histopathology, radiology, and computed tomography scanning. These calves were morphologically similar and displayed severe disproportionate dwarfism and reduced body weight. The syndrome was characterized by shortening and compression of the body due to reduced length of the spine and the long bones of the limbs. The vicerocranium had severe dysplasia and palatoschisis. The bones had small irregular diaphyses and enlarged epiphyses consisting only of chondroid tissue. The sire and a total of four affected half-sib offspring and their dams were genotyped with the BovineHD SNP array to map the defect in the genome. Significant genetic linkage was obtained for several regions of the bovine genome including chromosome 5 where whole genome sequencing of an affected calf revealed a COL2A1 point mutation (g.32473300 G > A). This private sequence variant was predicted to affect splicing as it altered the conserved splice donor sequence GT at the 5’-end of COL2A1 intron 36, which was changed to AT. All five available cases carried the mutant allele in heterozygous state and all five dams were homozygous wild type. The sire VH Cadiz Captivo was shown to be a gonadal and somatic mosaic as assessed by the presence of the mutant allele at levels of about 5 % in peripheral blood and 15 % in semen. Conclusions The phenotypic and genetic findings are comparable to a previously reported COL2A1 missense mutation underlying lethal chondrodysplasia in the offspring of a mosaic French Holstein sire (Igale Masc). The identified independent spontaneous splice site variant in COL2A1 most likely caused chondrodysplasia and must have occurred during the early foetal development of the sire. This study provides a first example of a dominant COL2A1 splice site variant as candidate causal mutation of a severe lethal chondrodysplasia phenotype. Germline mosaicism is a relatively frequent mechanism in the origin of genetic disorders and explains the prevalence of a certain fraction of affected offspring. Paternal dominant de novo mutations are a risk in cattle breeding, especially because the ratio of defective offspring may be very high and be associated with significant animal welfare problems.
