Female chromosomes in cockerel ejaculates

We describe a polymerase chain reaction which amplifies part of the Eco RI repeat unit of the fowl W chromosome. The resulting 447 bp fragment enables DNA from female birds to be identified. The composition of this DNA is confirmed by a nested polymerase chain reaction which specifically amplifies a known internal 263 bp region in this fragment. Using this technique it is possible to follow the fate of female cells in male germline chimaeras. The polymerase chain reaction fragment can be traced in cells of the embryonic and hatchling gonad and in adult sperm implying that cells containing the W chromosome are capable of being processed through the avian testis.

On the troublesome relationship of feminism and terrorism: representing the female terrorist in contemporary art

This paper analyses tendencies in debates about cultural representations of terrorism to assume that artists make critical interventions, while the mass media circulates stereotypes. Some recent feminist analyses of female terrorist acts have re-instituted essentialist arguments in which violence and terrorism is described as inherently masculine, while women are by nature pacifist, so that femininity is the antithesis of militarism. More progressive analyses mostly tend to expose the circulation of stereotypes and their gender bias, in order to protest the misrepresentation of women in violence. These analyses do not construct alternative accounts. Through an analysis of two works by artists Hito Steyerl and Sharon Hayes, the paper argues that some of the moves to re-image the question of women, violence and agency have already been made in contemporary art practices. Through analysing legacies of terrorism and feminism, it becomes possible to rethink the question of agency, militancy and the nature of political art. The paper appears in an edited interdiscplinary collection arising from a conference at Universität der Bundeswehr in Munich. It relates to wider projects involving collaborations with Birkbeck and Edinburgh on representations of terrorism and on violence and contemporary art.

‘Scripture its own interpreter’: Mary Martha Sherwood, the Bible and female autobiography

This is a reading of the work of Mary Martha Sherwood, the Victorian Evangelist and Children’s Author (and pupil at the Abbey School, Reading). Based upon research on Sherwood’s private correspondences and diary conducted at UCLA with the aid of a Mitzi Myers (this before my arrival at Reading), the essay offers a radical reinterpretation of her work. Previously understood in terms of a rigid, if self-contradictory and ‘anxious’, Evangelism, the essay reads the diary through Sherwood’s little known Biblical scholarship. Through this I argue that Sherwood grants her own writing the status of Biblical truth precisely because of its contradictions and ‘anxiety’.

An Examination of the factors that shape the subjectivities of female art students in Initial Teacher Training

The school subject of Art and the profession of the primary school teacher are gendered female and both are considered low status within the field of Education and other professional areas of society. A number of sociological studies have examined the impact of gendered socialisation and habitus on females’ career choices and various educational initiatives have been put in place over the years to encourage females to select subjects and/or pursue career paths normally associated with males. Yet Art and primary school teaching continue to be a popular choice with middle class girls. Based on a critical ethnographic study of female BAED Art students, who are training to be primary school teachers, this study is an examination of the many factors, historically and contemporaneously that have shaped and continue to shape the subjectivities of females and frame their aspirations and ambitions. Within this discourse significant aspects of the history of Art and Art Education that have contributed to and influenced the construction of the female artist, and their consequent impact on artistically talented females’ personal identity as artists, are also examined.

Escherichia coli isolates from extraintestinal organs of livestock animals harbour diverse virulence genes and belong to multiple genetic lineages

Escherichia coli, the most common cause of bacteraemia in humans in the UK, can also cause serious diseases in animals. However the population structure, virulence and antimicrobial resistance genes of those from extraintestinal organs of livestock animals are poorly characterised. The aims of this study were to investigate the diversity of these isolates from livestock animals and to understand if there was any correlation between the virulence and antimicrobial resistance genes and the genetic backbone of the bacteria and if these isolates were similar to those isolated from humans. Here 39 E. coli isolates from liver (n=31), spleen (n=5) and blood (n=3) of cattle (n=34), sheep (n=3), chicken (n=1) and pig (n=1) were assigned to 19 serogroups with O8 being the most common (n=7), followed by O101, O20 (both n=3) and O153 (n=2). They belong to 29 multi-locus sequence types, 20 clonal complexes with ST23 (n=7), ST10 (n=6), ST117 and ST155 (both n=3) being most common and were distributed among phylogenetic group A (n=16), B1 (n=12), B2 (n=2) and D (n=9). The pattern of a subset of putative virulence genes was different in almost all isolates. No correlation between serogroups, animal hosts, MLST types, virulence and antimicrobial resistance genes was identified. The distributions of clonal complexes and virulence genes were similar to other extraintestinal or commensal E. coli from humans and other animals, suggesting a zoonotic potential. The diverse and various combinations of virulence genes implied that the infections were caused by different mechanisms and infection control will be challenging.
