Abstract: This study aims to contribute to the growing body of knowledge on the circumstances under which adult education, in particular adult basic education, can support and occasionally initiate participatory development, social action and the realisation of citizenship rights. It traces developments in adult basic education in South Africa, and more specifically literacy and language learning, over the years 1981 to 2001, with reference to specific multilingual contexts in the Northern and Western Cape. The thesis is based on four individual studies, documenting an arc from grassroots work to national policy development and back. Study I, written in the early 1990s, critically examines approaches to teaching English to adults in South Africa at the time and proposes a participatory curriculum model for the additional language component of a future adult education policy. Study II is an account of attempts to implement this model and explores the implications of going to scale with such an approach. Studies III and IV draw on a qualitative study of an educator development programme after the transition to democracy. Study III uses Bourdieu's theory of practice and the concept of reflexivity to illuminate some of the connections between local discursive practices, self-formation, and broader relations of power. Study IV uses Iedema's (1999) concept of resemiotisation to trace the ways in which individuals re-shaped available representational resources to mobilise collective agency in community-based workshops. The summary provides a framework for these studies by locating and critiquing each within shifts in the political economy of South Africa. It reflects on a history of research and practice, raising questions to do with voice, justice, power, agency, and desire. Overall, this thesis argues for a reconceptualisation of ABET that is more strongly aligned with development goals and promotes engagement with new forms of state/society/economy relations.

Abstract: The privileged position of white commercial farmers in South Africa came to an end by the early 1990s, when political and policy changes removed the certainty provided by controlled marketing, protective tariffs and weak legislation regulating resource use and labour relations on farms and transformed agriculture into a sector that is highly sensitive to events on world markets. Despite their dwindling numbers and disarticulation from political power commercial farmers represent a dominant group in the countryside, retaining a near monopoly of resources and considerable power. Yet, the dynamics of change in the sector are not properly understood or well-researched. This paper presents data from a recent survey of 141 commercial farmers in the Limpopo, Western and Northern Cape Provinces that shows that they consider input costs, climate, labour matters, uncertainty about government policies and producer prices as the major pressures bearing down upon them. The adoption of farming methods which are less labour-intensive and the extension of labour legislation and minimum wages to farm workers, together have led to the decline of on-farm employment. Declining profit margins have resulted in a ‘shake-out’ in which only the most competitive enterprises can survive, leading to increased concentration in agricultural landholding and production. These processes imply that new entrants to agriculture with limited capital face daunting challenges, which policy needs to address. The paper explores these wider implications.

Abstract: An arsenic resistant Bacillus sp. UWC was isolated from fly ash acid mine drainage (FA-AMD) neutralised solids. A genomic library was prepared and screened in an arsenic sensitive mutant Escherichia coli strain for the presence of arsenic resistance (ars) genes. Sequence analysis of a clone conferring resistance to both sodium arsenite and sodium arsenate revealed homologues to the arsR (regulatory repressor), arsB (membrane located arsenite pump), arsC (arsenate reductase), arsD (second regulatory repressor and a metallochaperone) and arsA (ATPase) genes from known arsenic resistance operons. The Bacillus sp. UWC arsRBCDA genes were shown to be arranged in an unusual manner with the arsDA genes immediately downstream of arsC. URI: http://hdl.handle.net/10566/160 Files in this item: 1

Abstract: Objective: This retrospective survey highlighted the characteristics of children less than six years of age presenting with early childhood caries(ECC) who had two or more teeth extracted under intravenous sedation at the Tygerberg Oral Health Centre in Cape Town, South Africa. This survey was carried out in order to plan a community-appropriate intervention strategy. Methods: Records of 140 patients kept by the pediatric Dentistry Division met the inclusion criteria and were included in this survey. Most of the patients originate from economically disadvantaged areas. Results: Diet, feeding and oral hygiene habits were shown to be the most significant factors that contributed to the development of ECC in these patients. All the children were either breast- or bottle-fed past one year of age. 93.6% of the children went to sleep with the bottle or while on the breast and 90% of them were fed on demand during the night. On average, breastfeeding was stopped at 9 months of age compared to bottle-feeding that, on average, was stopped at a much later mean age of 23 months. Where oral hygiene practices were concerned, 52.6% of children brushed their own teeth without supervision. Frequency of brushing varied between subjects. Conclusion: The results of this study have demonstrated that there is a need for culturally appropriate education campaigns to inform parents (especially those in disadvantaged communities) about the importance of oral health and the prevention of oral disease.

Abstract: The rights to food and basic nutrition have been implemented rather unsystematically in South Africa through a hodgepodge of policies and indirectly by legislation. In view of the dearth of jurisprudence, this paper sought to tease out the meaning of children’s right of access to food as well as their right to basic nutrition, to analyse the significance of, and correlation between, these two rights, and to consider their implications for South African law and policy.

Abstract: The United Nations Convention on the Rights of the Child (CRC) through its reporting framework for nation states has prompted increasing interest on the measuring and monitoring of child well-being. The domains and indicators included in the repertoire of country measures of child well-being have mostly been constructed and monitored by adults, usually social scientists and government officials. This study explored children’s own understandings of children’s well-being. Sixteen focus groups were conducted with 200 children between the ages of 9 and 16 years. The study identified protection and safety, basic needs, community resources and psychosocial issues as the key domains of well-being. The study further highlighted the importance of perceiving well-being as an integrated whole consisting of closely interacting components rather than as a discrete multidimensional phenomenon.

Abstract: This chapter will examine the current actions, including lifestyle measures, for the prevention and management of non-communicable diseases within a South African context. It will also focus on the biological, behavioural and social determinants of health. Interventions and initiatives directed at primary, secondary and tertiary prevention of chronic non-communicable diseases are also discussed. This chapter ends with recommended lifestyle changes, which can be taken to influence the adoption of healthy lifestyles, and therefore reduce the risks for chronic non-communicable diseases.

Abstract: Background: Comprehensive information is needed on the epidemiology and burden of chronic pain in the population for the development of appropriate health interventions. This study aimed to determine the prevalence, severity, risk indicators and responses of chronic pain among adults in Ngangelizwe, Mthatha, South Africa. Method: A cross-sectional survey utilising structured interviews of a sample of adult residents was used. Interviews elicited information on socio-demographic characteristics, general health status, and the prevalence, duration, frequency, severity, activity limitation and impact of chronic pain. Results: More than 95% (n = 473) of the sampled adults participated in the study. Of these, 182 [38.5%, 95% confidence interval (CI): 36.3-42.5%] reported chronic pain in at least one anatomical site. The most common pain sites were the back and head. The median pain score was 5 on a scale of 0 to 10 [interquartile range (IQR) = 4-7] and the median number of sites of pain was 1 (IQR = 1-2). Female gender [odds ratio (OR) = 2.6, 95% CI: 1.7-3.9] and being older than 50 years of age (OR = 3.5, 95% CI: 2.6-4.1) were identified as risk indicators for chronic pain in the sample. Over 65% of respondents reported that they self-treated; 92.1% had consulted with a doctor or nurse, 13.6% consulted a traditional healer, and 34.5% consulted a pharmacist because of their pain. Despite this, over 50% reported that relief of their pain was transient. Conclusion: Chronic pain is a common general complaint in this community, but there is a need for focused attention on women and the elderly.

Abstract: The purpose of this study was to evaluate the efficacy of two different 10% carbamide peroxide bleaching products just after treatment and after a 6-month follow-up period. Methods. Two 10% carbamide peroxide products (Opalescence PF andNiteWhite ACP) were applied nightly for 14 days, according to the manufacturers’ instructions. The color of teeth 11 and 21 of thirty-four subjects having A2 or darker teeth were measured with a spectrophotometer (L∗; a∗; b∗) before treatment, just after treatment (14 days) and after 6 months. Results and Conclusions. Both products produced significant whitening of teeth with total color change (ΔE∗ ab) of approximately 5.20 units. There was a significant improvement in all 3 color coordinates (L∗, a∗, and b∗) for up to 6 months postbleaching (P < .05). Nite White showed a higher degree of relapse (27%) than Opalescence (18%) over the 6-month period. It is suggested that rebleaching after 6 months is not necessary URI: http://hdl.handle.net/10566/587 Files in this item: 1

Abstract: This article analyses the function that code-switching plays in selected testimonies given at South Africa's Truth and Reconciliation Commission which followed the country's transition to democracy in 1994. In a number of testimonies, victims of human rights abuse under Apartheid code-switched into Afrikaans when recalling particularly offensive uses of language by the police. Within the code-switching literature, it is well recognised that a speaker's choice of code, particularly for quoted speech, is a strategy for performing different kinds of local identities which index a range of social meanings and relationships (Alvarez-Caccamo 1996, Koven 2001). Thus code-switching may serve a complex evaluative function although the meanings it generates are very context- dependent. In order to explore this role in the testimonies in this paper, I use the appraisal theory of Systemic Functional Linguistics (Martin & White 2005). I argue that on a number of occasions, code-switching into a particular variety of Afrikaans is used by testifiers as a strategy to invoke negative judgement: it has the effect of associating the police with a particular racist ideology and positioning them for our sanction. Further, it works together with other engagement resources to insert a recognisable historical voice into the text, thereby expanding the heteroglossic nature of the discourse while simultaneously allowing the speakers to signal their rejection of that voice and the ideologies it represents. In the current SFL literature, however, code-switching has not been noted as an appraisal resource. In the light of the examples from the TRC testimonies, I argue that, in multilingual contexts, code-switching has the potential to invoke complex evaluative meanings and should be included in the appraisal framework as an evaluative resource.

Abstract: Despite his international status, the impact of Constantin Cavafy’s poetry on South African letters has gone largely unnoticed. This article draws attention to the range of Cavafy's, influence on the local poets, writers, critics and cultural activists, particularly during the 1970s and 1980s, but directs most of its attention to two early short stories by Achmat Dangor, ‘The Homecoming’ and ‘Waiting for Leila’, and his most recent novel Bitter Fruit. In all of these works Dangor refers directly and indirectly to Cavafy’s poetry, his sexuality, his evocations of place and his use of Greek mythology, particularly in one of his most famous poems ‘Ithaka’. The article also addresses Dangor’s ambivalence towards Cavafy, particularly the disjuncture between Cavafy’s ironic, apolitical modernism, modernism’s appeal to Dangor, his desire to produce accessible protest literature and his need to justify recourse to the classics in Africa.

Abstract: This bibliography is aimed at collating information relating to community-based natural resource management (CBNRM) in the Southern African region across different sectors and themes. It was primarily compiled to offer material support to researchers participating in the ‘Breaking New Ground’ – People Centred Approaches to Natural Resource Management and Development Programme – a joint venture of the Centre for Applied Social Sciences, University of Zimbabwe (CASS) and the Programme for Land and Agrarian Studies, University of the Western Cape (PLAAS). It is also aimed at providing a resource to practitioners, policy- and decision-makers and researchers in southern Africa. The bibliography includes references to a variety of previously undocumented sources of information. The focus of this work, whilst including annotations on wildlife, moves beyond this traditional view of CBNRM to include other sectors. It embraces second or third generation issues ranging from the contribution of CBNRM to rural livelihoods and resource condition, to investigating policy issues around CBNRM and issues of power and authority over land and natural resources.

Abstract: BACKGROUND: Community health workers (CHWs) are lay people trained to assist with health care in their communities. This study took place at two sites in Khayelitsha, a township in the Cape Peninsula, from 2000 to 2002. OBJECTIVES: To describe the process of developing an intervention programme for primary prevention of noncommunicable diseases (NCDs) in general and cardiovascular disease in particular, targeting CHWs. METHOD: Forty-four CHWs were assigned to either an intervention or a control group. The intervention group, living in Site C, received training on lifestyle modification with emphasis on healthy eating and physical activity, while the control group, living in Site B, did not receive any training until a year later. The process was undertaken in four stages. Stage 1 involved assessment of the CHWs’ risk factors by obtaining anthropometric measurements. CHWs were interviewed and focus group discussions were held on the socio-cultural factors associated with body weight and body image, and barriers to physical activity. Stage 2 involved developing and implementing a training programme for primary prevention of NCDs among CHWs. Stage 3, conducted at Site C, involved a situational assessment of available resources in the community for promoting healthy lifestyles. The fourth and final stage involved the implementation of community interventions by the CHWs. RESULTS: A large percentage of CHWs were overweight and obese, and therefore at risk for NCDs. They had misconceptions about causes and treatment of these diseases, and also lacked knowledge on nutrition and the risk of high fat intake. Easy access to cheap unhealthy food, rather than fresh fruit and vegetables, limited their ability to make healthy food choices. The findings from stage 1 led to a community participatory intervention. CONCLUSIONS: Developing community-targeted interventions for NCDs can be achieved by involving CHWs at the initial stage and utilising a multifaceted approach. Education of community members and CHWs does not guarantee behaviour modification. Unless the environment encourages healthy living, NCDs will continue to be a burden in the poor populations of South Africa. URI: http://hdl.handle.net/10566/236 Files in this item: 1

Abstract: Objectives: The aim of this study is to compare the success rate obtained when applying either a calcium hydroxide (Dycal) base or a zinc oxide-eugenol (Kalzinol) base following the traditional ferric sulfate pulpotomy. Methods: Patients were either treated in the chair or under general anaesthesia. All teeth had to have radiographic evidence of caries close to the pulp. After haemostasis was achieved with damp cotton pellets, ferric sulfate was applied to the pulpal stumps. Half of the cases then received a Dycal base followed by a cured layer of Vitrebond and a permanent amalgam restoration. The other half of the cases received a base of zinc oxide-eugenol (Kalzinol) followed by an amalgam restoration. The cases were followed up every 6 months for one year (ie. 2 follow-up visits). Radiographs were taken at each follow-up visit. Results: Overall, teeth treated with Dycal demonstrated a higher failure rate when compared with those that received the Kalzinol base. Abscess formation and internal resorption were the most common causes of failure. Even though the Kalzinol base demonstrated greater success, there were still quite a few failures. Conclusion: This study demonstrates that calcium hydroxide cannot be recommended as a medicament in primary tooth pulpotomies. URI: http://hdl.handle.net/10566/415 Files in this item: 1

Abstract: Fuel cells, as devices for direct conversion of the chemical energy of a fuel into electricity by electrochemical reactions, are among the key enabling technologies for the transition to a hydrogen-based economy. Among the various types of fuel cells, polymer electrolyte membrane fuel cells (PEMFCs) are considered to be at the forefront for commercialization for portable and transportation applications because of their high energy conversion efficiency and low pollutant emission. Cost and durability of PEMFCs are the two major challenges that need to be addressed to facilitate their commercialization. The properties of the membrane electrode assembly (MEA) have a direct impact on both cost and durability of a PEMFC. An overview is presented on the key components of the PEMFC MEA. The success of the MEA and thereby PEMFC technology is believed to depend largely on two key materials: the membrane and the electro-catalyst. These two key materials are directly linked to the major challenges faced in PEMFC, namely, the performance, and cost. Concerted efforts are conducted globally for the past couple of decades to address these challenges. This chapter aims to provide the reader an overview of the major research findings to date on the key components of a PEMFC MEA. URI: http://hdl.handle.net/10566/166 Files in this item: 1

Abstract: This contribution explores the significance but also the immense complexities of Christian discourse on confessing guilt within the context of climate change. It draws especially on South African discourse on confessing guilt in the context of apartheid. The argument of the essay is twofold: Christians with an enduring large carbon footprint may wish to confess their guilt in this regard, but typically find it difficult to live from God’s liberating forgiveness and are therefore prone to rather desperate efforts to save the world themselves. By contrast, Christians with a small carbon footprint may opt for alternative understanding of salvation, namely in terms of redemption from the looming threat of climate change.

We are developing a community-centered approach to learn how interaction techniques can compensate for poor communication across the Digital Divide. Preliminary trials have yielded interfaces that deal with poor quality by adapting Instant Messaging techniques for multiple modalities, providing improved semi-synchronous communication. Lessons learned suggest new ways to design user interfaces specifically for the developing world. URI: http://hdl.handle.net/10566/591 Files in this item: 1
