Abstract: Biodiesel has attracted increasing interest and has proved to be a good substitute for fossil-based fuels due to its environmental advantages and availability from renewable resources such as refined and waste vegetable oils. Several studies have shown that biodiesel is a better fuel than the fossil-derived diesel in terms of engine performance, emissions reduction, lubricity and environmental benefits. The increasing popularity of biodiesel has generated great demand for its commercial production methods, which in turn calls for the development of technically and economically sound process technologies. This paper explores the applicability of ultrasound in the optimization of low-cost feedstock – in this case waste cooking oil – in the transesterification conversion to biodiesel. It was found that the conversion efficiency of the waste oil using ultrasound was higher than with the mechanical stirring method. The optimized variables of 6:1 methanol/oil ratio at a reaction temperature of 30 °C and a reaction time of 30 min and 0.75% KOH (wt/wt) catalyst concentration was obtained for the transesterification of the waste oil via the use of ultrasound.

Abstract: In this article the Derrida/Foucault debate is scrutinised with two closely related aims in mind: (1) reconsidering the way in which Foucault’s texts, and especially the more recently published lectures, should be read; and (2) establishing the relation between law and madness. The article firstly calls for a reading of Foucault which exceeds metaphysics with the security it offers, by taking account of Derrida’s reading of Foucault as well as of the heterogeneity of Foucault’s texts. The article reflects in detail on a text of Derrida on Foucault (‘Cogito and the History of Madness’) as well as a text of Foucault on Blanchot (‘Maurice Blanchot: The Thought from Outside’). The latter text shows that Foucault was at times acutely aware of the difficulty involved in exceeding metaphysics and that he realised the importance in this regard of a reflection on literature. These reflections tie in closely with Foucault’s History of Madness as well as with Derrida’s reflections on literature and on madness. Both Derrida and Foucault contend that law has much to learn from literature in understanding the relation between itself and madness. Literature more specifically points to law’s ‘origin’ in madness. The article contends that a failure to take seriously this origin, also in the reading of Foucault’s lectures, would amount to a denial by law of itself.

Abstract: This paper discusses the role of a writing centre in creating spaces for talk about and change in disciplinary writing pedagogy. It asks how collaborative partnerships between disciplinary academics and Writing Centre practitioners might be established and nurtured sustainably. Drawing on insights from two collaborations with academics in political studies and law, the article asserts that writing centre practitioners play a valuable role in talking about and changing the way academic writing and literacy is taught in the disciplines. This is shown by working consistently with the understanding that critical reading, thinking and writing are literacy acts rather than generic skills and must therefore be learned and practiced in the disciplines. By supporting disciplinary academics in re-examining course outcomes, materials and assessments, and moving away from a ‘skills approach’ to writing, it is shown that building discipline-specific spaces for writing and literacy development is possible through these collaborative partnerships.

Abstract: In this article I discuss some of the ways in which Drum tended to ascribe ‘modernity’ to particular practices and processes in opposition to other practices and processes portrayed as ‘traditional’. In mid-twentieth-century South Africa, dominant discourses tended to signal (white) male adulthood through independent decision making alongside financial autonomy. In contrast African discourses tended to signal male adulthood through proximity to family members, through respect for age and seniority and through deference to the praxis of ‘tradition’. In the representations of black men in its pages, Drum magazine negotiated a somewhat disorderly path through these competing racialised discourses. I suggest that Drum’s claim that black males were indeed men was made through highlighting and condoning practices that demonstrated similarities and continuities between subordinate black and dominant white versions of manhood. In challenging the racial discourse the magazine paradoxically found itself simultaneously reinforcing western rather than African versions of manhood.

Abstract: This chapter explores changing representations of fatherhood and masculinity in Drum magazine over the course of the 1950s. In the early 1950s men were portrayed in close proximity to their children and adult masculinities were tied to being a father. Over the course of the 1950s this changed such that by the 1960s adult masculinities were portrayed outside the home and disconnected and distinct from their offspring.

Abstract: A growing shift towards research and evidence based practice in academia is associated with requirements to disseminate research results in the form of publication in peer reviewed journals. Mentoring has been identified as an important component of developing young authors, as it increases confidence and competence, and facilitates professional development. This led to the formation of a support group to stimulate peer-review publication in the physiotherapy department at the University of the Western Cape. The Kirkpatrick Framework of Evaluation was used to evaluate the success of the mentoring process which made use of a participatory action research methodology. The writing group consisted of nine academic members of staff and took place over ten weeks. The programme included writing, giving feedback, discussion and peer review on a weekly basis. Focus group discussions were taped and transcribed in order to evaluate the mentoring process by identifying relationships within the data and categorising key concepts, which were shaped into a thematic framework. The findings indicated that participants experienced a variety of emotions throughout the programme, with an overall feeling of personal growth by the end. In addition, participants also reported improved writing, reviewing and communication skills. Six months following the programme, six participants had submitted at least one article to a peer reviewed journal. It is clear from this study that some academics still find the task of writing and reviewing articles daunting, and that guidance and support in the form of a writing programme can be useful.

Abstract: With the rapid development of powerful protein evolution and enzyme-screening technologies, there is a growing belief that optimum conditions for biotransformation processes can be established without the constraints of the properties of the biocatalyst. These technologies can then be applied to find the ‘ideal biocatalyst’ for the process. In identifying the ideal biocatalyst, the processes of gene discovery and enzyme evolution play major roles. However, in order to expand the pool genes for in vitro evolution, new technologies, which circumvent the limitations of microbial culturability, must be applied. These technologies, which currently include metagenomic library screening, gene-specific amplification methods and even full metagenomic sequencing, provide access to a volume of ‘sequence space’ that is not addressed by traditional screening.

Abstract: The question of how to make higher education more inclusive has been a central concern in South Africa and elsewhere over the past two decades. However, in South Africa there remains a disjuncture between policy aimed at promoting inclusivity and the experiences of students and staff in the higher education sector. In this article, the relationship between equity of access and equity of outcomes and the expectations that follow from these policy imperatives are examined from the perspective of Nancy Fraser’s normative framework of social justice. In particular, her notion of misframing is used to analyze the current situation in the higher education sector in South Africa. The article concludes that a focus on individual higher education institutions is not sufficient to gain a perspective on the social arrangements required for participatory parity in higher education, and in fact, such a focus is an instance of misframing and thus a form of injustice.

Abstract: Background: The objective of this study was to examine missed opportunities for participation in a prevention of mother-to-child transmission (PMTCT) programme in three sites in South Africa. A rapid anthropological assessment was used to collect in-depth data from 58 HIV-positive women who were enrolled in a larger cohort study to assess mother-to-child HIV transmission. Semistructured interviews were conducted with the women in order to gain an understanding of their experiences of antenatal care and to identify missed opportunities for participation in PMTCT. Results: 15 women actually missed their nevirapine not because of stigma and ignorance but because of health systems failures. Six were not tested for HIV during antenatal care. Two were tested but did not receive their results. Seven were tested and received their results, but did not receive nevirapine. Health Systems failure for these programme leakages ranged from nonavailability of counselors, supplies such as HIV test kits, consent forms, health staff giving the women incorrect instructions about when to take the tablet and health staff not supplying the women with the tablet to take. Conclusion: HIV testing enables access to PMTCT interventions and should therefore be strengthened. The single dose nevirapine regimen is simple to implement but the all or nothing nature of the regimen may result in many missed opportunities. A short course dual or triple drug regimen could increase the effectiveness of PMTCT programmes. URI: http://hdl.handle.net/10566/429 Files in this item: 1

Abstract: This essay builds on the conference on “Mission in the 21th century: New models and strategies in a world of diversity” held in Livingstone, Zambia from 25 March to 1 April 2004. It offers some background to the tension between mission as “evangelism” and as “development” which was addressed at this conference. It then describes some of the insights emerging from this conference, with specific reference to the description of mission as “crying and struggling with others to live today with dignity.” It provides some perspectives on this description on the basis of an exegesis of the second half of the Lord's prayer. The conclusion to the essay suggests that further reflection is required on the relationship between soteriology and missiology. URI: http://hdl.handle.net/10566/385 Files in this item: 1

Abstract: A new record of Crambionella stuhlmanni is reported from the east coast of South Africa. The material is described using quantitative morphological data, and mitochondrial (CO1) and nuclear (ITS-1) sequence data. The species can be diagnosed by a combination of morphological features including the presence of conical projections on velar lappets, the absence of orbicular appendages among mouthlets and the short length of the terminal club on the oral arm. Mitochondrial sequence data unambiguously delineate C. stuhlmanni as a separate species from C. orsini, and phylogenetic analyses support its placement within the monophyletic genus, Crambionella URI: http://hdl.handle.net/10566/249 Files in this item: 1

Abstract: This essay enquires into the depictions of Justice through the ages, as well as the myths surrounding these depictions, more particularly in Egypt, Greece, and Rome, as well as in modern times. The essay departs in significant respects from traditional interpretations by seeking to gain from the insights in relation to mythology and the use of symbols provided by psychoanalysis, structuralism, Heidegger’s thinking on Being, and deconstruction. Insofar as psychoanalysis is concerned, of importance in the present context is Freud’s analysis of symbolism in the interpretation of dreams and in myths, specifically insofar as he contends that the symbols employed there almost invariably have a sexual connotation. The approach of Claude Lévi-Strauss is the focus of the detour through structuralism, with Lévi-Strauss challenging certain of the most prevalent ideas in relation to myth, such as that there is some original version of a myth, usually believed to be the earliest version. In the case of Heidegger, of particular importance is his challenge to us “moderns” to not be too quick in our belief that we understand ancient texts or the ancient conceptions of deities. He more specifically places in question the common belief that the gods and goddesses are persons or that they are abstract personifications of concepts. Derrida, in his analysis of the texts of Freud, Lévi-Strauss and Heidegger, further develops the ideas of each of these thinkers, seeking thereby to go beyond the Oedipus complex, beyond the security of structure, and beyond Being. After an analysis of depictions of the goddesses Ma’at, Themis, Dike and Justitia, based on the insights gained in the preceding analysis, the essay concludes with a reading of the blindfold of Justice in her modern guise which seeks to exceed metaphysics. Drawing specifically on Derrida’s analysis of blindness in drawing, it arrives eventually not at the essence, but the an-essence of justice. URI: http://hdl.handle.net/10566/288 Files in this item: 1

Abstract: This paper considers the role of ‘measurement’ and other forms of poverty knowledge in a context where the nature and direction of global economic growth is creating ‘surplus populations’ suffering various forms of marginalisation in the global economy. It links the development of different forms of poverty knowledge with the ways in which states and non-state agents seek to ‘govern’ poverty and poor populations, and with the ‘biopolitics’ whereby calculations are made about the differential allocation of resources towards different sectors of the global population. The paper argues that addressing the root causes of poverty requires social actors to go beyond the narrow limits of institutionally sanctioned and bureaucratically invested ‘poverty knowledge’ that currently dominate policy thinking. Rather than seeking to understand poverty by measuring the characteristics of members of populations, they should try to understand poverty as an aspect of social relations, and try to come to grips with differential insertion of populations in the fields of force of modern globalised capitalism. Analysis should abandon simple notions of ‘marginalisation, and come to grips with the agency of poor people and the complex relationships between informality, marginality, exclusion and incorporation. Ultimately, however, a more nuanced understanding of the role of poverty knowledge in present day biopolitics does not bring with it any easy answers: rather, it challenges applied social scientists to be more aware of the responsibilities they bear as producers of 'useful' knowledge in a time of increased global instability.

Abstract: This contribution explores John Calvin's position on natural theology. The point of departure is not so much the much discussed notions of a sensus divinitatis or of the semen religionis, but the role played by the human senses in coming to knowledge of God in the first place. How can God's presence be recognised? How can human language (that which is natural), from below, express the inexpressible? How is it possible to speak of God in the first place? This article suggests that Calvin's remarkably sophisticated understanding of signification is the clue to respond to these questions. His position is discussed on the basis of the reading strategy of catena and commentary. The author finally offers some concluding observations on the relationship between signifier, signified and referent in human language about God.
