Abstract: The racial desegregation of the student bodies of historically white universities in South Africa has had significant political implications for student politics and university governance. I discuss two key moments in the governance history of the University of Cape Town (UCT) critically. The first involves the experience of racial parallelism in student governance in the late 1980s and early 1990s, making specific reference to the re-conceptualisation of the UCT Students’ Representative Council (SRC) as a ‘NUSAS-SRC’, along with the recognition of the political salience of race in the student body. The second traces the origins of the demographic representivity rule in the university’s statute to student demands for the dissolution of the UCT Council, and its replacement by a Transformation Forum in the early 1990s. I thus show that the recognition of race as politically significant in university governance is the outcome of a deliberate struggle, by students in general, and black students in particular, to de-privatise and politicise any sense of racial/racist marginalisation, and therefore to open up race as a topic for deliberation in the political realm of the post-apartheid university. Thus, the institutionalisation of race has come to serve the interests of the struggle for non-racialism. Description: Research article URI: http://hdl.handle.net/10566/226 Files in this item: 1

Abstract: E-learning has come of age in South African higher education but scepticism, caution and an inadequate reward system for innovative teaching methods have resulted in a slow uptake by academics. Within this milieu the author pioneered a course in the ACE School Librarianship programme. The study describes the e-learning experiences of the course participants gleaned from questionnaire responses to questions related to experiences of ICTs, the Internet and online learning, ability to navigate the e-learning environment, utilization of elements of the learning management system and implementation of course ideas in their respective schools and personal lives. The study also provides an opportunity for the author to reflect on her pioneering experiences with e-learning and how she would approach it differently next time. The main lessons learned were that 1) the e-learning environment is not necessarily intuitive and participants need opportunities to digest novel features such as the discussion forum; 2) several of the advantages and disadvantages of e-learning that appear in the research literature are identified in this study; and 3) setting up an e-learning course is best achieved incrementally.

Abstract: Protest politics in South Africa has a long history and has been deployed differentially in different historical moments. Whereas protests formed an important vehicle during the fight against apartheid, their rebirth and propulsion to the centre of the struggles in the post-apartheid dispensation have come as a surprise to many. A majority of these protests, so-called ‘service delivery protests’, are reported as emanating from communities’ dissatisfaction with municipal service delivery as well as problems relating to lack of communication between council and councillors on the one hand and citizens on the other. In this article, we interrogate data from five study sites located in Cape Town and Pietermaritzburg. While we found support for the importance of service delivery, our data contradicts many widely held assertions as regards what causes these protests. We were able to show, for example, that these so-called ‘service delivery protests’ may actually emanate from reasons that extend beyond service delivery. Since our data indicates that levels of participation in Cape Town are higher than in Pietermaritzburg on the one hand, illustrating perhaps the different provincial contexts, there is also variation between the relatively high participation rates of the ‘black African’ sites of Langa and Khayelitsha, on the one hand, and the lower rates of the ‘coloured’ site of Bonteheuwel, on the other, which we ascribe to the disengagement of the community in Cape Town, from both local and national politics.

Abstract: This paper identifies the link between gatekeepers and corruption, and examines how money laundering mechanisms are used to conceal the proceeds of corruption. In order to successfully trace and recover stolen assets, we need to understand how gatekeepers utilize various money laundering mechanisms and offshore financial centres. This writing highlights how gatekeepers operating in the private sector, wittingly or unwittingly, use their expert knowledge of the international financial system to facilitate corruption by helping corrupt leaders legitimate, secure, and obfuscate the movement of the proceeds of corruption within the global banking system. It also looks at potential alternative responses to further curb gatekeeper’s roles in the money laundering process. URI: http://hdl.handle.net/10566/241 Files in this item: 1

Abstract: This article traces the politics of meaning-fixing with respect to the role of the defence force as apartheid declined from the mid-1980s, as it was negotiated from a current to a past organising principle of the “security imaginary” in the period 1990 to 1994 and as the post-apartheid period commenced after the 1994 elections.

Abstract: This paper reports on three years of research and fieldwork with a rural wireless Internet Protocol communication project. We built a long-range WiFi network and custom communication software to support a rural telehealth project in the remote Eastern Cape. We report on our work using cellular networks, devices and applications as reference technologies because our users and beneficiaries are very comfortable with them. Of most concern are the technological and contextual issues affecting take up of the systems we designed. The paper intends to provide a summary analysis of our experience so that others in the field can learn from our successes and mistakes with respect to rural Information and Communication Technology for Development (ICT4D) in a South African context.

Abstract: Introduction: E-learning has been integrated into the curriculum of the School of Nursing (SON) because it supports the principles of the case-based approach adopted by the SON. Aim: The primary aim was to gather baseline data on e-learning by exploring the perceptions and experiences of the first pilot group of undergraduate nursing students who were exposed to this strategy. Methods: A descriptive cross -sectional quantitative design was used to collect data regarding the students’ understanding and value of e-learning, the benefits and skills gained, challenges experienced, by means of a structured, open-ended questionnaire. Convenience sampling was used because the questionnaire was distributed to the 87, third year undergraduate nursing students who completed the Primary Mental Health Care module in June 2006. Microsoft Excel software was used for the capturing and analysis of the data. Results: The findings indicate that 19.5% did not have an accurate theoretical understanding of e-learning in spite of being exposed to at least two sessions of KNG training. The data confirmed that e-learning affords convenience, flexibility and improved access to digital resources. Initial confusion and system down times were cited as important challenges. Conclusion: Although some students struggled initially, the majority (87.8%) succeeded finally in mastering e-learning and regarded the experience as valuable in that 90% rated it as beneficial enough to be recommended to other students.

Abstract: The structure and process of rehabilitation of stroke patients affects the outcomes of the patients. The aim of this study was to determine the structure and process of rehabilitation of stroke patients at Community Health Centres (CHCs) in the Western Cape, South Africa. A quantitative descriptive study was conducted. Questions and archived records were used to collect the data. The study sample used to collect information related to the structure consisted of therapists (16) employed at the centres; while the study sample used to collect information related to the process consisted of 100 first time stroke patients. Descriptive statistics were conducted using Excel and SPSS . The results of the study revealed that there is a lack of occupational and speech therapy services at the centres forming part of the study sample. At centres where these services are provided the frequency and intensity with which the services are received by the patients is extremely low. Further research is needed to determine if the decreased intensity is only as a result of decreased availability of services or if inability of stroke clients to access the services also plays a role URI: http://hdl.handle.net/10566/522 Files in this item: 1

Abstract: This field study included the whole population of children aged 10–15 years (77 from a 0.19 mg/L F area; 89 from a 3.00 mg/L F area), with similar nutritional, dietary habits and similar ethnic and socioeconomic status. The fluoride concentration in the drinking water, the bone mineral content, the bone density and the degree of dental fluorosis were determined. The left radius was measured for bone width, bone mineral content, and bone mineral density. The mean fluorosis score was 1.3 in the low fluoride area and 3,6 in the high fluoride area. More than half the children in the low fluoride area had no fluorosis (scores 0 and 1) while only 5% in the high fluoride area had none. Severe fluorosis (30%) was only observed in the high fluoride area. The Wilcoxon Rank Sum Test indicated that fluorosis levels differed significantly (p < 0.05) between the two areas. No relationships were found between dental fluorosis and bone width or between fluorosis and bone mineral density in the two areas (Spearment Rank correlations). A significant increase in bone width was found with age but no differences amongst and boys and girls. A significant positive correlation was found in the high fluoride area between bone mineral density over age. In the 12-13 and 13-14 year age groups in the high fluoride area, girls had higher bone mineral densities. However, a significant negative correlation (p<0.02) was found for the low fluoride area (0.19 mg/L F) over age. URI: http://hdl.handle.net/10566/404 Files in this item: 1

Abstract: This paper presents a fully decentralised peer-topeer voice communication tool intended for use across mobile ad hoc networks (MANET) by distributed groups who desired collaboration. We examined the synergy between MANETs and peer-to-peer virtual overlay networks which allowed the creation of ad hoc applications. One style of communication considered suitable for task oriented distributed group collaboration was push-to-talk. This research was focused on providing a push-to-talk communication platform suitable for deployment across MANETs. The research methodology employed was a proof of concept approach within a classical experimental computer science paradigm. We developed a prototype which used JXTA, a peer-to-peer virtual overlay network, to provide push-to-talk functionality across MANETs. Guaranteed delivery of messages was provided via a peer-to-peer voicemail delivery system. While the system did what intended we show that JXTA had a problem with the efficient delivery of voice samples. URI: http://hdl.handle.net/10566/508 Files in this item: 1

Abstract: Executive Summary: By almost any measure, most South African public schools, and schools in the Western Cape, are underperforming academically. For a number of years, there has existed a wide degree of consensus among education stakeholders, and particular government, that the problems in our schools extend beyond academic under-achievement. Massive budget allocations, overhauling curricular, restoring skewed learning resources, retraining educators and attempting to deal with the more pressing community problems and social ills that influence the results of a school are all necessary interventions. But, unless there is a concurrent improvement of schools from a „business‟ management point of view, there is no guarantee that the resources allocated to schools, both materially and in the form of educators, will be optimally deployed. Principals need to be occupied with the tasks of managing and leading teaching and learning i.e. instruction leadership, not managing routine administration. In recognising the potential of school administrative personnel to provide relief and support for the administrative role of principals, the Western Cape Government initiated a training course – the CSBA – in July 2008 for school business administrators. The ground-breaking pilot programme was completed in February 2010. Thereafter the WCED commissioned an evaluation of the results achieved. The purpose of the evaluation is to inform the WCED‟s plans for development of the course going forward. This report represents a synopsis of the findings of the evaluation.

Abstract: BACKGROUND: While the importance of promoting equity to achieve health is now recognised, the health gap continues to increase globally between and within countries. The description that follows looks at how the Cape Town Equity Gauge initiative, part of the Global Equity Gauge Alliance (GEGA) is endeavouring to tackle this problem. We give an overview of the first phase of our research in which we did an initial assessment of health status and the socio-economic determinants of health across the subdistrict health structures of Cape Town. We then describe two projects from the second phase of our research in which we move from research to action. The first project, the Equity Tools for Managers Project, engages with health managers to develop two tools to address inequity: an Equity Measurement Tool which quantifies inequity in health service provision in financial terms, and a Equity Resource Allocation Tool which advocates for and guides action to rectify inequity in health service provision. The second project, the Water and Sanitation Project, engages with community structures and other sectors to address the problem of diarrhoea in one of the poorest areas in Cape Town through the establishment of a community forum and a pilot study into the acceptability of dry sanitation toilets. METHODS: A participatory approach was adopted. Both quantitative and qualitative methods were used. The first phase, the collection of measurements across the health subdistricts of Cape Town, used quantitative secondary data to demonstrate the inequities. In the Equity Tools for Managers Project further quantitative work was done, supplemented by qualitative policy analysis to study the constraints to implementing equity. The Water and Sanitation Project was primarily qualitative, using in-depth interviews and focus group discussions. These were used to gain an understanding of the impact of the inequities, in this instance, inadequate sanitation provision. RESULTS: The studies both demonstrate the value of adopting the GEGA approach of research to action, adopting three pillars of assessment and monitoring; advocacy; and community empowerment. In the Equity Tools for Managers Project study, the participation of managers meant that their support for implementation was increased, although the failure to include nurses and communities in the study was noted as a limitation. The development of a community Water and Sanitation Forum to support the Project had some notable successes, but also experienced some difficulties due to lack of capacity in both the community and the municipality. CONCLUSION: The two very different, but connected projects, demonstrate the value of adopting the GEGA approach, and the importance of involvement of all stakeholders at all stages. The studies also illustrate the potential of a research institution as informed 'outsiders', in influencing policy and practice. URI: http://hdl.handle.net/10566/171 Files in this item: 1

Abstract: Michel Foucault provides a radical challenge to the liberal approach to power and law, which is echoed by Jacques Derrida. Important differences exist between the analyses of Foucault and Derrida which should not be overlooked. This essay proceeds on the basis of an awareness of these differences, yet it at the same time attempts to bring these thinkers closer together, with reference specifically to the thinking of Freud. It is often said that Foucault does not offer an alternative to that which he criticises or that his analyses do not provide for a way in which to escape from the effects of power. By specifically focusing on Foucault’s reliance on the notion of ‘play’ in Society Must Be Defended, it is submitted that an ‘escape’ is in fact provided for. The deconstructive reading of Foucault which is presented here attempts to ensure that Foucault does not remain trapped within metaphysics. URI: http://hdl.handle.net/10566/286 Files in this item: 1

Abstract: The Anaximander fragment, in the readings of both Heidegger and Derrida, speaks of that which exceeds positive law. In this article, the author provides a detailed reading of Heidegger’s Der Spruch des Anaximander, showing how Heidegger relates this fragment to his thinking of Being, the latter having been ‘forgotten’ by metaphysics. Heidegger’s reading at the same time involves a contemplation of technology and of the ontological relation of beings to each other. Derrida’s reading of Heidegger’s Der Spruch highlights specifically those parts of Heidegger’s text where that which precedes Being’s gathering, Being’s disjoining or dissemination, is pointed to. This disjoining, Derrida contends, speaks of the gift of a day more ancient than memory itself and ties in closely with certain aspects of the thinking of Marx. Derrida’s focus on that which precedes Being is in turn related to his contemplation of the law or condition of possibility of technology and also of that which makes possible a relation to the other as other. This condition of possibility, or the gift of Being, which Heidegger’s text also speaks of, involves a ‘higher law’ which can serve as a ‘measure’ for the evaluation, interpretation and transformation of positive law.

Abstract: The Polymerase Chain Reaction (PCR) has facilitated the detection of unculturable microorganisms in virtually any environmental source and has thus been used extensively in the assessment of environmental microbial diversity. This technique relies on the assumption that the gene sequences present in the environment are complementary to the “universal” primers used in their amplification. The recent discovery of new taxa with 16S rDNA sequences not complementary to standard universal primers suggests that current 16S rDNA libraries are not representative of true prokaryotic biodiversity. Here we re-assess the specificity of commonly used 16S rRNA gene primers and present these data in tabular form designed as a tool to aid simple analysis, selection and implementation. In addition, we present two new primer pairs specifically designed for effective ‘universal’ Archaeal 16S rDNA sequence amplification. These primers are found to amplify sequences from Crenarchaeote and Euryarchaeote type strains and environmental DNA. URI: http://hdl.handle.net/10566/169 Files in this item: 1

Abstract: The sponge genus Strongylodesma is reviewed and redefined, and now accommodates eight closely related species. The type species of Strongylodesma Le´vi is redescribed and an additional two new species are described from the Indo-Pacific: S. novaecaledoniae sp. nov. and S. tongaensis sp. nov. Several specimens previously identified as species of Batzella (Poecilosclerida: Chondropsidae) have been re-assigned to Strongylodesma, as the new species S. purpureus sp. nov. and S. nigra sp. nov. With the description here of new species from the Pacific Ocean and Caribbean Atlantic, the biogeographical distribution of Strongylodesma now appears to be generally tropical with a subtropical South African component, whereas previously it was only known from South Africa. Although species of Strongylodesma have not previously been recorded from the intermediate locations (Western Indian Ocean, South-east Asia, central west Pacific, and New Zealand), re-evaluation here will facilitate more readily the recognition of taxa in these intermediate regions, if they exist, in the future. The species are not widespread, except perhaps along the south-east coast of South Africa, and where they occur they are not abundant. Species occur over a wide depth range, from the intertidal in Tsitsikamma, South Africa, to 140 m in the Caribbean. URI: http://hdl.handle.net/10566/248 Files in this item: 1

Abstract: In this essay, one of Derrida’s early texts, Plato’s pharmacy, is analysed in detail, more specifically in relation to its reflections on writing and its relation to law. This analysis takes place with reference to a number of Derrida’s other texts, in particular those on Freud. It is especially Freud’s texts on dream interpretation and on the dream-work which are of assistance in understanding the background to Derrida’s analysis of writing in Plato’s pharmacy. The essay shows the close relation between Derrida’s analysis of Plato’s texts and Freud’s study of the dream-work. The forces at work in dreams, it appears, are at play in all texts, which in turn explains Derrida’s contentions in relation to the pharmakon as providing the condition of possibility of Plato’s texts. The essay furthermore points to the continuity between this ‘early’ text of Derrida and his ‘later’, seemingly more politico-legal texts of the 1990s. A close reading of Plato’s pharmacy, with its investigation via ‘writing’ of the foundations of metaphysics, and thus also of the Western concept of law, is obligatory should one wish to comprehend how Derrida attempts to exceed the restricted economy of metaphysics through his analysis of concepts such as justice and hospitality.
