Comparison of heat stability of goat milk subjected to ultra-high temperature and in-container sterilisation

Goatmilk with and without stabilizing salt was subjected to in-container and UHTsterilization. Heatstability was assessed by measuring the amount of sediment in the milk. Without stabilizing salts, goatmilk usually produced less sediment when subjected to in-containersterilization compared with UHT processing. Addition of stabilizing salts up to 12.8 mM resulted in a progressive increase in sediment for in-containersterilization. In contrast, adding stabilizing salts at 6.4 mM initially reduced sediment formation in UHT-treated milk but addition of stabilizing salts at 12.8 mM increased sediment formation. Adding stabilizing salts to goatmilk increased pH, decreased ionic calcium, and increased ethanol stability. Adding up to 2 mM calcium chloride increased sediment formation more after UHT treatment than after in-containersterilization. These results suggest that no single mechanism or set of reactions causes milk to produce sediment during heating and that the favored pathway is different for UHT and in-containersterilization processes. Poor heatstability could be induced both by increasing ionic calcium and by decreasing it. Ethanol stability is not a good indicator of heatstability for in-containersterilization, but it may be for UHTsterilization, if milk does not enter the region of poor heatstability found at low concentrations of ionic calcium.

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.

Peaceful coexistence? The role of religious schools and NGOs in the growth of female secondary schooling in Bangladesh

Bangladesh Rural Advancement Committee (BRAC), a non-governmental organisation (NGO), runs a large number of non-formal primary schools in Bangladesh which target out-of-school children from poor families. These schools are well-known for their effectiveness in closing the gender gap in primary school enrolment. On the other hand, registered non-government secondary madrasas (or Islamic schools) today enrol one girl against every boy student. In this article, we document a positive spillover effect of BRAC schools on female secondary enrolment in registered madrasas. Drawing upon school enrolment data aggregated at the region level, we first show that regions that had more registered madrasas experienced greater secondary female enrolment growth during 1999–2003, holding the number of secular secondary schools constant. In this context we test the impact of BRAC-run primary schools on female enrolment in registered madrasas. We deal with the potential endogeneity of placement of BRAC schools using an instrumental variable approach. Controlling for factors such as local-level poverty, road access and distance from major cities, we show that regions with a greater presence of BRAC schools have higher female enrolment growth in secondary madrasas. The effect is much bigger when compared to that on secondary schools.

“The suffering black male body and the threatened white female body": ambiguous bodies in Candyman

This article explores the roles of monster and victim as experienced through the body, and considers how the relationship between violence and the body affects the presentation of these roles through close analysis of performance in Candyman (Bernard Rose, 1992). I aim to demonstrate that commitment to such a detailed approach, offers a more intricate and rewarding critical interaction, reflecting the complexity of narrative film. Consideration of the particulars of performance is crucial, in its affect on our engagement with the performer and their physical presence. Through this attention I intend to demonstrate how the seemingly fixed role of monster is in fact more fluid than first apparent, that monster and victim can co-exist in the same body. Candyman’s physicality and the way it is presented foregrounds the oscillations between violence and suffering, the relationship between the body and the violence inflicted on and by it, ambiguities which are also found in the heroine’s development, thus enhancing the film’s striking preoccupation with the shifting parallels between monster and victim.

Effect of seasonal variation on some physical properties and heat stability of milk subjected to ultra-high temperature and in-container sterilisation

Heat stability was evaluated in bulk raw milk, collected throughout the year and subjected to ultra-high temperature (UHT) or in-container sterilisation, with and without added calcium chloride (2 mM), disodium hydrogen phosphate (DSHP, 10 mM) and trisodium citrate (TSC, 10 mM). More sediment was observed following in-container sterilisation (0.24%) compared with UHT (0.19%). Adding CaCl2 made the milk more unstable to UHT than to in-container sterilisation, while adding DSHP and TSC made the milk more unstable during in-container sterilisation than to UHT processing, although TSC addition increased the sediment formed by UHT processing. Better heat stability was observed in autumn and winter than in spring and summer following UHT. However, following in-container sterilisation, samples with added stabilising salts showed significantly improved heat stability in autumn, whereas with added CaCl2, the best heat stability was observed in spring. No correlation was found between urea and heat stability.
