Abstract: This report outlines the community’s attempts to develop and use the land that has been restored to it in terms of the Restitution of Land Rights Act 22 of 1994 (‘Restitution Act’). It examines the nature and content of the post-settlement support received and draws lessons from the community’s experience that might inform the development of a strategy for post-settlement support provision by land reform institutions and associated agencies.

Abstract: BACKGROUND: While much is written about the scale up of HIV counselling and testing (HCT) and antiretroviral therapy (ART), little research has been done on the expansion of routine preART HIV care. OBJECTIVE: To assess the quality of preART care in Cape Town and its continuity with HCT and ART. METHODS: The scale up of the HCT, preART and ART service platform and programmatic support in Cape Town is described. Data from the August 2010 routine annual HIV/TB/STI evaluation, from interviews with 133 facility managers and a folder review of 634 HCT s who tested positive and 1115 clients receiving preART HIV care are analysed. RESULTS: Historically the implementation and management of preART care has been relatively neglected compared with the scale-up of HCT and ART. The CD4 count was done on 77.5% positive HCT clients and 46.6% were clinically staged - crucial steps that determine the care path. There were: gaps in quality of care - 32.2% of women had a PAP smear; missed opportunities for integrated care - 67% were symptomatically screened for tuberculosis; and positive prevention - 48.3% had contraceptive needs assessed. Breaks in the continuity of care of preART clients occurred with only 47.2% of eligible clients referred appropriately to the ARV service. CONCLUSION: While a package of preART care has been clearly defined in Cape Town, it has not been fully implemented. There are weaknesses in the continuity and quality service delivered that undermine the programme objectives of provision of positive prevention and timeous access to ART.

Abstract: Background: While there is evidence to suggest that teaching practices in clinical education should include activities that more accurately reflect the real world, many educators base their teaching on transmission models that encourage the rote learning of knowledge and technical skills. Technology-mediated instruction may facilitate the development of professional attributes that go beyond “having” knowledge and skills, but there is limited evidence for how to integrate technology into these innovative teaching approaches. Methods: This study used a modified Delphi method to help identify the professional attributes of capable practitioners, the approaches to teaching that may facilitate the development of these attributes, and finally, how technology could be integrated with those teaching strategies in order to develop capable practitioners. Open-ended questions were used to gather data from three different expert panels, and results were thematically analysed. Results: Clinical educators should not view knowledge, skills and attitudes as a set of products of learning, but rather as a set of attributes that are developed during a learning process. Participants highlighted the importance of continuing personal and professional development that emphasised the role of values and emotional response to the clinical context. To develop these attributes, clinical educators should use teaching activities that are learner-centred, interactive, integrated, reflective and that promote engagement. When technology-mediated teaching activities are considered, they should promote the discussion of clinical encounters, facilitate the sharing of resources and experiences, encourage reflection on the learning process and be used to access content outside the classroom. In addition, educational outcomes must drive the integration of technology into teaching practice, rather than the features of the technology. Conclusions: There is a need for a cultural change in clinical education, in which those involved with the professional training of healthcare professionals perceive teaching as more than the transmission of knowledge and technical skills. Process-oriented teaching practices that integrate technology as part of a carefully designed curriculum may have the potential to facilitate the development of capable healthcare graduates who are able to navigate the complexity of health systems and patient management in ways that go beyond the application of knowledge and skills.

Abstract: Summary Points: * In South Africa, as in other jurisdictions, ‘‘Big Food’’ (large commercial entities that dominate the food and beverage environment) is becoming more widespread and is implicated in unhealthy eating. * ‘‘Small food’’ remains significant in the food environment in South Africa, and it is both linked with, and threatened by, Big Food. * Big Food in South Africa involves South African companies, some of which have invested in other (mainly, but not only, African) nations, as well as companies headquartered in North America and Europe. * These companies have developed strategies to increase the availability, affordability, and acceptability of their foods in South Africa; they have also developed a range of ‘‘health and wellness’’ initiatives. Whether these initiatives have had a net positive or net negative impact is not clear. The South African government should act urgently to mitigate the adverse health effects in the food environment in South Africa through education about the health risks of unhealthy diets, regulation of Big Food, and support for healthy foods.

Abstract: OBJECTIVES: To explore perceptions about factors associated with body weight and body image among black female community health workers (CHWs) living and working in Khayelitsha, Cape Town. DESIGN: A descriptive, cross-sectional study. Setting. Khayelitsha, a black township in Cape Town, South Africa. SUBJECTS: Forty-four black, female, Xhosa-speaking CHWs working in Khayelitsha. Outcome measures. Anthropometric measures (height, weight, and waist circumference) were taken. Body mass index (BMI) was computed as a measure to estimate total body fat. Waist circumference was used as a measure of abdominal obesity. Focus groups were employed to explore beliefs and attitudes about body size. Information from the focus group discussions was used to develop a semi-structured questionnaire for individual interviews, which were conducted to validate the data from the focus groups, and to assess knowledge on causes and risk factors associated with obesity. A body satisfaction question was also included in the questionnaire. Body image was measured using body shape drawings (pictograms). RESULTS: Of the 44 women measured, 2 had normal weight (BMI 18.5 - 24.9 kg/m2), 2 were overweight (BMI 25 - 30 kg/m2), 25 were obese (BMI 30 - 40 kg/m2) and 15 were extremely obese (BMI ≥ ( 40 kg/m2). A moderately overweight shape (BMI 27 kg/m2) was preferred; this was associated with dignity, respect, confidence, beauty, and wealth. Perceived causes of obesity were eating the wrong food, skipping breakfast and worries about debts, husbands/partners and teenage children. Negative aspects of obesity included body aches and tiredness. CONCLUSION: This study emphasises the prevalence of obesity among urban black women in South Africa, particularly among CHWs. Socio-cultural, behavioural and environmental factors seem to influence the development of obesity in this population. URI: http://hdl.handle.net/10566/256 Files in this item: 1

Abstract: The aerobic biodegradation of high-concentration, to 24 g l –1 , 2-propanol (IPA) by a thermophilic isolate ST3, identified as Bacillus pallidus , was successfully carried out for the first time. This solvent-tolerant B. pallidus utilized IPA as the sole carbon source within a minimal salts medium. Cultivation was carried out in 100-ml shake flasks at 60°C and compared with cultivation within a 1-l stirred tank reactor (STR). Specific growth rate () was about 0.2 h–1 for both systems, with a maximum cell density of 2.4 x 10 8 cells ml–1 obtained with STR cultivation. During exponential growth and stationary phase, IPA biodegradation rates were found to be 0.14 and 0.02 g l –1h–1, respectively, in shake-flask experiments, whereas corresponding values of 0.09 and 0.018 g l –1h–1 were achievable in the STR. Generation of acetone, the major intermediate in aerobic IPA biodegradation, was also monitored as an indicator of microbial IPA utilization. Acetone levels reached a maximum of 2.2–2.3 g l–1 after 72 and 58 h for 100-ml and 1-l systems, respectively. Both IPA and acetone were completely removed from the medium following 160 and 175 h, respectively, during STR growth, although this was not demonstrated within shake-flask reactions. Growth of B. pallidus on acetone or IPA alone demonstrated that the maximum growth rate () obtainable was 0.247 h–1 at 4 g l–1 acetone and 0.202 h–1 at 8 g l–1 IPA within shake-flask cultivation. These results indicate the potential of the solvent-tolerant thermophile B. pallidus ST3 in the bioremediation of hot solvent-containing industrial waste streams.

Abstract: The scarification in Aké is invested with major significance apropos Soyinka’s ideas on African subjectivity. Scarification among the Yoruba is one of the rites of passage associated with personal development. Scarification literally and metaphorically “opens” the person up socially and cosmically. Personal formation and self-realization are enabled by the Yoruba social code brought into being by its mythology. The meaning of the scarification incident in Aké is profoundly different. Determined by the form of autobiography which creates a self-constituting subject, the enabling Yoruba sociocultural context is elided. The story of Soyinka’s personal development is allegorical of the story of the development of the modern African subject. For Soyinka, the African subject is a rational subject whose constitution precludes the splitting of the scientific and spiritual which is a consequence of the Cartesian rupture. The African subject should be open to other subjects and the object world. Subjectivity constituted by the autobiographical mode closes off the opening up symbolically signalled by scarification.

Abstract: This article compares the representation of African borders in the 14th-century travelogue of Ibn Battuta, the 19th-century travel narrative of Richard Burton and the 21st-century travel writing of Paul Theroux. It examines the mutually constitutive relationship between conceptions of literal territorial boundaries and the figurative boundaries of the subject that ventures across borders in Africa. The border is seen as a liminal zone which paradoxically separates and joins spaces. Accounts of border crossings in travel writing from different periods suggest the historicity and cultural specificity of conceptions of geographical borders, and the way they index the “boundaries” of the subjects who cross them. Tracing the transformations in these conceptions of literal and metaphorical borders allows one to chart the emergence of the dominant contemporary idea of “Africa” as the inscrutable, savage continent.

Abstract: This paper shows that a borehole dilution experiment using common salt is a useful technique for better understanding of some hydrogeological features of a fractured aquifer. A sense of such tracer experiments was performed in the campus site aquifer, a hydrological experiment site of the Institute for Ground Studies at the University of the Orange Free State in Bloemfontein. It is demonstrated that the model for use in homogeneous aquifers may be adapted in fractured aquifers. Results have revealed valuable information on hydraulic parameters of the fracture system at different scales. Profiles of electrical conductivities monitored in several boreholes can be used to locate horizontal fracture zones in the aquifer. These results may provide an important guide to formulate realistic conceptual models for borehole protection zoning. The experiment can also serve as a reference to future experiments of this kind in Karoo aquifers which cover some 50% of the subcontinent of Southern Africa.

Abstract: Connecting people across the Digital Divide is as much a social effort as a technological one. We are developing a community-centered approach to learn how interaction techniques can compensate for poor communication across the Digital Divide. We have incorporated the lessons learnt regarding Social Intelligence Design in an (abstract) device called the SoftBridge. The device allows information to flow from endpoints through adapters (getting converted if necessary), and out to destination endpoints. Field trials are underway with two communities in South Africa, disadvantaged deaf users and an isolated rural community. First lessons learned show that we have to design user interfaces that allow users to understand and cope with delay (latency) as a necessary consequence of our approach.

Abstract: This paper describes the design and evaluation of two browser-based video communication prototypes that support sign language communication between Deaf people. The research explores combinations of technologies, protocols and architectures with the hope to eventually provide a mobile video system that Deaf people would want to use enough to pay for. Technology products, and in particular mobile and web-based video communication systems, are designed for the majority of people in general. These are not necessarily suitable for Deaf people who have very different physiological and cultural needs. We focus on browser-based video transmission because end-users need not fiddle with application installation. Web-browsers are also common on mobile phones. This paper compares two prototypes built with Adobe Flex and the fifth version of the HyperText Markup Language, H.264 and H.263 video codecs, and PC and mobile phone implementations. The paper describes the motivation, related work, methods, prototype design and finally analyses results of user experiments conducted with Deaf users.

Abstract: This paper reviews the types of business models, or landuse models, being implemented in land reform projects involving the transfer of rural land to communities and other groups in South Africa, under both the restitution and redistribution programmes. It draws heavily on the series of Diagnostic Studies prepared as part of the Sustainable Development Consortium’s (SDC) work on post-settlement support, but also draws from other studies on restitution, notably that conducted by the Community Agency for Social Enquiry (CASE) in 2005, and the wider literature on redistributive land reform in South Africa.

Abstract: Introduction:This article revisits a vexed and much-debated question: when is it 'fair' for an employer, in the course of restructuring its business, to dismiss an employee for declining to accept changes in her or his terms and conditions of employment? The background to this question is the fiercely competitive climate in which many businesses, exposed to the full force of global economic pressures, find themselves, giving rise to the need for constant adaptation and, conversely, the spectre of dismissal for many employees. The legal context is a lengthening series of Labour Court (LC) and Labour Appeal Court (LAC) decisions in which the meaning of substantive fairness under these circumstances has been considered in great detail, but in divergent ways.

Abstract: This paper describes work in progress on call capacity optimization for voice over Internet Protocol on wireless mesh networks. In a developing country such as South Africa, evidence has shown that rural inhabitants find it difficult to afford the voice services offered by cellular networks. Voice over Internet Protocol is known for its affordability relative to cellular voice services, therefore deploying such services for rural communities will not only benefit rural inhabitants but also offer economic advantages to service providers. We are interested in the provision of voice services with rural wireless mesh networks. Unfortunately voice on mesh networks can experience packet loss and delays that cause reduction in voice quality. Transmission of small voice packets over wireless mesh networks imposes high overhead that leads to a tremendous decrease in call capacity. Therefore, we aim to study the performance of voice over 802.11 wireless mesh networks and evaluate packet aggregation mechanisms that merge small voice packets into a single large packet, in order to preserve voice quality with more calls. We will implement and evaluate packet aggregations mechanisms on a 'mesh potato' network with iterative cycles of laboratory experiments using a network simulator to collect data for performance evaluation.

Abstract: Delineation of capture zones for groundwater source protection is normally performed by using numerical codes which are based on the porous medium flow equation. However, boreholes are often sited in or along permeable dykes or single fracture zones through which aquifers are drained. It is very important to take into account dyke-influenced aquifers. This paper makes use of Linesink to simulate permeable dyke or fractured zones and utilises the pathline distribution to delineate the capture zones. Conditions when the influence of a fractured dyke can be considered negligible are also discussed through comparison with stagnation point in a uniform flow field. The approach may be sufficient to illustrate protection zoning requirements when dyke aquifers are considered. URI: http://hdl.handle.net/10566/811 Files in this item: 1
