Abstract: This paper sets to work on strategies for forging new and critical humanities at the institutional site of the university that appears to be trapped in the legacies of apartheid. The paper suggests that the university's responses to apartheid might hold the key for the realignment of its critical commitments in the post-apartheid present. Rather than merely invoking the Enlightenment traditions of the modern university as sufficient grounds for proclaiming a post-apartheid reorientation, I track the career of notions of academic freedom and university autonomy in the outlines of complicity. I show how the concepts of academic freedom and autonomy obscured a prior contract with the state and how that complicity extended a process of subjection. By deploying the postcolonial strategy of abusing the Enlightenment, the paper outlines the failure of opposing apartheid in the name of academic freedom and autonomy. That failure, I argue, resulted in an inability to investigate the relationship be¬tween the university and the state and blinded the university to its role in the creation of racial subjects. Rather than merely casting the university in terms of the foundational concepts of academic freedom and university autonomy, I suggest that it might be more productive to consider the epistemological and political potential of a renewed reference to the Enlightenment. Apartheid's University, cast as continuity of the Enlightenment legacy, might allow us to rewrite its abject script in the direction of resisting the forms of subjection supported by that process of normalisation.

Abstract: Background: Mobile phone technology has demonstrated the potential to improve health service delivery, but there is little guidance to inform decisions about acquiring and implementing mHealth technology at scale in health systems. Using the case of community-based health services (CBS) in South Africa, we apply a framework to appraise the opportunities and challenges to effective implementation of mHealth at scale in health systems. Methods: A qualitative study reviewed the benefits and challenges of mHealth in community-based services in South Africa, through a combination of key informant interviews, site visits to local projects and document reviews. Using a framework adapted from three approaches to reviewing sustainable information and communication technology (ICT), the lessons from local experience and elsewhere formed the basis of a wider consideration of scale up challenges in South Africa. Results: Four key system dimensions were identified and assessed: government stewardship and the organisational, technological and financial systems. In South Africa, the opportunities for successful implementation of mHealth include the high prevalence of mobile phones, a supportive policy environment for eHealth, successful use of mHealth for CBS in a number of projects and a well-developed ICT industry. However there are weaknesses in other key health systems areas such as organisational culture and capacity for using health information for management, and the poor availability and use of ICT in primary health care. The technological challenges include the complexity of ensuring interoperability and integration of information systems and securing privacy of information. Finally, there are the challenges of sustainable financing required for large scale use of mobile phone technology in resource limited settings. Conclusion: Against a background of a health system with a weak ICT environment and limited implementation capacity, it remains uncertain that the potential benefits of mHealth for CBS would be retained with immediate large-scale implementation. Applying a health systems framework facilitated a systematic appraisal of potential challenges to scaling up mHealth for CBS in South Africa and may be useful for policy and practice decision-making in other low- and middle-income settings.

Abstract: This paper examines the effectiveness of linguistic analysis in developing scientific thinking skills and scientific attitudes. It reports on a project established at a South Africa university in South Africa which engaged students in the analysis of code-mixed data. Students who participated in the project showed gains in being able to analyze linguistic data using problem solving skills. While transfer of such skills to mainstream science teaching was not investigated, the study confirms the effectiveness of linguistic analysis in engaging students in the activities associated with the development of skills for science.

Abstract: The South African Deaf community has very limited telephony options. They prefer to communicate in sign language, a visual medium. Realtime video over Internet Protocol is a promising option, but in reality, the quality is often not enough for the Deaf to be able to understand each other’s sign language. Furthermore, these applications were not design specifically for the Deaf. This paper introduces an asynchronous video chat system to provide better quality video at the expense of increased latency. It determined a codec/transmission protocol combination in the laboratory environment and tested it out with actual Deaf users. This paper will address the results based on comparison between different codecs, transmission protocol on asynchronous video communication for the Deaf.

Abstract: In recent years, southern African governments have made a number of important commitments on international and regional levels to combat HIV/ AIDS. The subregion has also seen a number of strategic developments such as the drafting and implementation of the SADC HIV/AIDS Policy Framework for 2003-2007 and the appointment by the UN Secretary-General of a Task Force on Women, Girls and HIV/AIDS in Southern Africa.It is now generally accepted that the intersections between gender-based violence and HIV/AIDS are among the most significant of the gendered dimensions of this pandemic. It is noteworthy that the UN Special Rapporteur on Violence Against Women devoted her 2005 thematic report to these intersections. She observed that while some progress is being made separately on ending violence against women and on stemming the spread of HIV/AIDS, national and international efforts would be vastly more effective if they addressed the interconnectness between the two pandemics.

Abstract: One way for Deaf people to communicate with hearing people over the telephone is to use a voice relay. The service is often provided with a human relay operator that relays text into voice, and vice versa, on behalf of the Deaf and hearing users. In developed countries, voice relay is frequently subsidised by governments or service providers. There is no such service in South Africa. We have built several automatic voice relay systems for a disadvantaged Deaf community in Cape Town. This paper describes how we augmented a general-purpose communication system for voice relay. Kiara is a fully open source Instant Messaging, voice and video over Internet Protocol communication system based on the Session Initiation Protocol. We integrated automatic speech recognition and text-to-speech technologies into Kiara to provide real-time automatic voice relay for relayed communication. As it stands, Kiara can also be used for standard voice and video relay with a human operator. URI: http://hdl.handle.net/10566/619 Files in this item: 1

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: 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 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: 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: Crinum macowanii has been used extensively in traditional medicines for treatment of various illnesses such as oedema and ‘heart disease’. Previous studies of the crude bulb extracts on Langendorff perfused isolated rat hearts indicated a positive inotropic effect. The aim of this study was to isolate and characterize compound(s) from C. macowanii with cardiovascular effects similar to that observed with the crude extracts of the plant. The methanol extract of dried bulbs was extracted for alkaloids, and structural elucidation of the isolated alkaloid identified it as hippadine. The cardiovascular effects of hippadine was evaluated in vitro in isolated perfused rat hearts using the “double sided” working heart system. Perfusion with 0.5 μg/ml and 5.0 μg/ml hippadine in Krebs-Hanseleit buffer led to significant decreases in coronary flow, aortic output, cardiac output, systolic pressure, and heart rate, accompanied by increases in diastolic pressure. Hippadine exhibited a negative chronotropic and inotropic effect on the isolated rat heart and is responsible either partly or fully for the cardiovascular effects of C. macowanii.
