MSc., Faculty of Science, University of Witwatersrand, 2011 / Studies of San rock art in southern Africa have appealed to researchers for specificities of individual rock art sites in order to counter the prevailing practice of conceptualising San rock art as a homogenous entity. This research attempts to analyse social interaction through looking at diverse ethnographies and how such ethnographies can reveal information regarding one rock art site. Individual rock art sites like Xoro Gwai can start to unravel the nuanced, diverse and complex nature of San religious beliefs and rites and how these beliefs were affected or influenced by social contact with other social formations.

Student No. 0107750D M.Sc(Med) Research Report / The prescription habits of general practitioners are continually under the scrutiny of ethical critics. There are numerous factors that influence a practitioner’s decision as to which antihypertensive agents to prescribe for the treatment of hypertension. As outlined in various international and national guidelines for the management of hypertension, the recommended treatment depends on ethnicity, current life-style, diet, smoking, age, gender, family history and possible underlying or secondary conditions such as diabetes mellitus, heart failure, isolated systolic hypertension, myocardial infarction, pregnancy, and evidence of coronary artery disease (CAD), stroke or peripheral vascular disease. Currently the control of blood pressure in patients with hypertension is far from optimal with over 70% of hypertensive patients being reported as having imperfect control. A number of factors related to the patient, the practitioner or the medication may explain the high incidence of inadequate blood pressure control. One possible explanation for the poor control of blood pressure may be that practitioners fail to comply with the guidelines. Hence the aim of my study was firstly to determine whether a practitioner’s decision as to which medication to prescribe in the treatment of hypertension is influenced by the Southern African Hypertension Society Guidelines. Secondly, in an attempt to assess the validity of the results of the primary analysis, the actual prescription habits (MediCross® database) were assessed and compared to the general practitioner’s recall of their prescription habits. Questionnaires were distributed to 320 MediCross® practitioners and prescription habits were identified and substantiated by the screening of an existing MediCross® database. I chose as my sample MediCross® general practitioners, as they are demographically representative of all major urban areas in South Africa; likely to be open-minded to supporting research and answering questionnaires (as MediCross® is part of a Clinical Research Site Management Organisation); and I had access to the database of the prescriptions made by MediCross® practitioners hence enabling me to fulfil my second objective. However, it must be kept in mind that these practitioners are representative of general practitioners in urban areas only (as the title of my research report indicates). My results show that 33.1% adhere to the guidelines (when a non-conservative definition of diuretics is used); 27% have heard of the guidelines and have a copy of them. When asked to give their own opinion however, 39% thought they adhered to the guidelines. The results also show that ACE inhibitors are the most commonly prescribed drug class for uncomplicated hypertension but a comparison to a MediCross® database, of which the quality is questionable, does not support this. As the response rate to the questionnaires was only 24.7%, these results are only a pilot study; however they suggest that few general practitioners use the guidelines or even have a copy of the guidelines. This pilot study suggests that the guidelines need to be distributed more widely. Furthermore the general practitioners that responded to the questionnaire indicated that the management of hypertension is difficult in that there is no single treatment regimen appropriate for all populations and each different patient. It was also their view that clinical guidelines for the management of hypertension should more accurately reflect the uncertainty of when to initiate treatment and individual variation if they are going to take these guidelines seriously and comply with them.

Faculty of Engineering and the Built Environment; Master of Science in Engineering; Research Report / The primary objective of this study was to develop a methodology for evaluating how the reliability profile of the typical South African Platinum concentrator plant is affected by firstly the size of the primary milling units incorporated in the circuit and secondly by the way that the primary milling units are configured. A methodology, together with a set of general expressions is presented which considers the Platinum concentrator as a stochastic process where the behaviour of the primary mill is a direct measure of the failure pattern of the overall concentrator. The reliability, availability and maintainability (RAM) of the primary mill, and hence the overall concentrator, is then determined by a combination of three different Markov models where each Markov model is used to evaluate and measure a separate set of reliability parameters. This approach effectively overcomes the computational complexity associated with large Markov models. The results of two case studies used to validate the methodology do indicate that the reliability, availability and maintainability profiles of large single stream Platinum concentrators could be fundamentally different from the conventional multiple stream primary mill configurations.

Student Number : 0213468X - MPh dissertation - School of Public Health - Faculty of Health Sciences / Background: Noise Induced Hearing Loss (NIHL) is increasingly being regarded as one of the most important Occupational diseases, especially in the mining industry. As most mining houses have put systems in place to try and control this problem it remains to be seen if existing controls are effective in achieving the intended objective of preventing hearing loss. This study was conducted in one of the big South African Diamond mines, which has a well resourced Hearing Conservation Program. Objectives: This study was conducted with the purpose of establishing if there has been additional incidence of NIHL in noise exposed workers during the observation period of five years. The other objective of this study was to determine the effect of age. Study design and method: The population in this study was made up of permanent employees of the mine. They were divided into low risk and high risk groups according to the noise/acoustic zoning of their work areas by the mine’s Occupation Hygiene Section, with the low exposure group acting as the control group. A retrospective record review was done using the Occupational Health records in the mine’s Occupational Health Centre. The period of observation spanned 1 January 1999 – 31 December 2004 (inclusive). Trends of the collated data were used to compare the two exposure groups with regard to the various outcomes that are commonly associated with hazardous noise exposure. Results: The outcomes that were analyzed in this study were: Incidence Rates for NIHL, Notching and Down-sloping. All these were observed to have occurred more among the exposed group during the period of observation. The incidence rates, in particular, were found to 92.8 per thousand person years in the high exposure group and 52.3 per thousand person years in the low exposure group. The statistical test that was used was the z-test and the results were z=5.844 with a p<0.05. Having decided on a significance level of 5% for the statistical test, this result was found to be statistically significant. This can be regarded as some proof that the exposed group had a worse outcome than their non-exposed counterparts. Another observation that was made was that the incidence of NIHL was proportionately higher among the older study subjects. Conclusion: Since the exposed group of workers was found to show statistically significant incidence of NIHL compared to the low exposure group it shows that the current Hearing Conservation Program (HCP) that is employed by the mine is not effective in preventing NIHL. However there were some limitations in the study design that preclude generalization of these results. Therefore a recommendation was made for a prospective cohort study to address these limitations.

Student Number : 8910202A - MPH research report - School of Public Health - Faculty of Health Sciences / An increasing number of people are migrating to South African urban centers (GJMC, 2000). There are various reasons that can be attributed to this migration; including the hope of finding employment and better living conditions. Recent urban migrants find themselves faced with the basic problem of lack of shelter and, depending on the migrant’s situation, they may choose to live in indoor shacks within the city center, backyard shacks in the black townships or join the growing number of informal settlement dwellers (GJMC, 2000). The number of informal settlements continues to grow at an alarming rate in Johannesburg (CEROI, 2000). This poses unique health care challenges as well as presenting the health care system with unusual disease conditions associated with general lack of infrastructure and services (CEROI, 2000). It has been established that the proportion of HIV infected patients is higher in people living in informal settlements when compared to people living in private houses (SAHR, 2000). Thus, it is expected that more people will be presenting with HIV and AIDS related illnesses in an informal settlement health center as compared to well-developed residential areas. This study aimed at exploring the prescribing patterns of health care givers for patients attending a health center in an informal settlement as well as to determine the major disease patterns prevalent in the area. The study was carried out in Davidsonville and OR Tambo clinics as well as Bophelong and Hikhensile clinics in Ivory Park. The study covered regions five, one and two respectively according to Gauteng metropolitan services area classification (GJMC, 2000). The findings of the study will help the appropriate policy makers improve the Essential Drug List and inform public health officials in formulating strategies that may lead to health status improvement for people living in informal settlements.

Thesis (Ph.D.)--University of the Witwatersrand, Faculty of Humanities, School of Education, 2014. / Abstract for PhD Thesis: An Investigation into the Teaching of English Literature at Senior Secondary School Level, with a Particular Emphasis on the Reason for Teaching Literature, the Selection of Texts, and Methodology Used. By David Edwin Robinson This thesis addresses three questions regarding education in South African High Schools: Why teach English literature? What English literature should be taught? How should English literature be taught? The thesis adopts an historical perspective in that it traces the lineages of influence from Britain in particular, and explores the attitudes and concerns of the academics and teachers of South Africa as they attempt to establish a rigorous discipline regarding South Africa’s literary heritage and the education curriculum. Theoretical concerns that are explored include the influence of the Cambridge School, the concepts presented by the Marxists and Cultural Materialists, and the position of Theory as it became more significant in the second half of the 20th Century. There is also recognition of scholarship deriving from the United States of America, in that the work of the New Critics and Harold Bloom are considered. The work of significant South African critics such as Guy Butler, Mike Kirkwood and Tim Couzens is also explored, and the attempt to grapple with English in a multilingual society is considered. The curriculum documents that emerged in the post-1994 era are critiqued, and there is reference to the work of Taylor and Vinjevold.

Student Number : 8546313 - PhD thesis - School of Arts - Faculty of Humanites / This thesis interrogates the extent to which the façades of, and decorative programmes in, selected South African public and commercial buildings erected during the decade 1930 – 40 may be understood as important indexes of the various ideological, social and historical concerns underpinning the construction of an imaginary of national belonging during this period. In the context of rapid urbanisation, burgeoning industrialisation, and rampant capitalism that characterise the period, issues of nationalism and political power are brought into sharp relief, with three political agendas competing for dominance: Afrikaner nationalism at one extreme and British imperialism at the other, with, from 1933 to the end of the decade, the insipid ‘South Africa First’ nationalism of the Smuts-Hertzog ‘fusion’ government occupying a highly contested space somewhere between the two. I argue in this thesis that the rhetoric of ‘unity in diversity’ that informs the fusion politics of the 1930s, and particularly its expression in the decorative programmes of public buildings provides for a more nuanced reading of the political and cultural landscape of 1930s South Africa than has been the case to date, where the focus has tended towards deconstructing the cultural nationalism of the 1930s in terms of the rise of Afrikaner nationalism. Moreover, it also serves as a compelling reference point against which to assess contemporary South African attempts to re-narrate notions of nationhood, and the extent to which difficult arguments around ethnicity, autochthony, and the construction of imaginary new ‘publics’ are articulated in post-apartheid public architecture. Chapter 1 is a review of the literature that informs this thesis; both as regards the art historical discourse on South African inter-World War art and architecture, as well as theoretical issues arising from writing on nationalism, national identity, and the role that art and architecture plays in evolving the nation code. In Chapters 2 and 3, I consider the ways in which the notions of identity arising from fusion politics are played out in the decorative programmes of two significant public buildings, South Africa House in London (1933) in Chapter 2 and the Pretoria City Hall (1935) in Chapter 3. I argue that both these buildings are classic examples of the manifestation in architectural terms of the hybrid identity being forged by the centrist ‘South Africa first’ ideologues, in so far as their decorative programmes express an uncomfortable alliance between the entrenched values of British imperialism and a burgeoning Afrikaner nationalism. In Chapter 4, I contrast the decorative programme of the headquarters of the new Afrikaner insurance companies SANTAM and SANLAM (1932) with that of the new corporate headquarters of the Commercial Union Assurance Company (1932), a British owned firm that had had a presence in Cape Town since 1863. The differences in effect of the decorative programmes of these two buildings serve to illuminate the extent of the ideological posturing of volkskapitalisme and its construction of a ‘modern African/Afrikaner’ identity within the imperialist heartland of Cape Town. These debates are brought into sharp relief by the third example discussed in this chapter, the Old Mutual building (1940), the decorative programme of which effectively conflates these concerns with modernity and nationalism in order to construct a hybrid ‘South Africanism’ that neatly elides Boer and Brit imaginings. In conclusion, I show in Chapter 5 how the post-apartheid South African situation presents an interesting case study in terms of constructing an imaginary of national belonging rooted in similar notions of ‘unity in diversity’. Examples here include important national architectural commissions like the legislature buildings for the newly constituted provinces of Mpumalanga (1999) and the Northern Cape (2003), as well as the new Constitutional Court in Johannesburg (2004). In this chapter, I interrogate these debates, and conclude by pointing to parallels with the case studies from the 1930s. The post-1994 examples in question have been widely celebrated as exemplary of a new and appropriate response to the challenges of public building in democratic South Africa. I suggest, however, that the lessons of the 1930s should serve as a reminder that the ostensible dichotomy between ‘good’ (civic) and ‘bad’ (ethnic) nationalism is perhaps not as natural and obvious as it may appear, and that both are equally problematic.

Along with various contextual factors, the method of literacy instruction is recognised as one of the main reasons for low levels of literacy learning both locally and internationally. Harcombe’s CATLI process is offered as an alternative literacy methodology, firstly since its constructivist, ecosystemic underpinnings endeavour to address as many contextual issues as is possible, and secondly, because the CATLI process attempts to address some of the gaps in other literacy instructional programmes. The current study aimed to evaluate the CATLI process as a viable alternative to traditional methods of literacy instruction. In addition, the study aimed to evaluate the effectiveness of using the constructivist approach to train university students in the CATLI process. The sample comprised trainee learning support specialists and one parent per learner receiving the CATLI intervention at the community centre at a Johannesburg university in 2007. Quantitative and qualitative data obtained by means of questionnaires and extant records provided evidence that all learners showed improvement in literacy skills as well as general development, ascribing the effectiveness of the process to being underpinned soundly by social constructivism and associated theories. For the same reason, trainees considered their training sufficient.

Submitted in the partial fulfilment for the Degree of Master of Arts in the Department of African Literature University of the Witwatersrand, March 2017 / This research reads the popular literature genre, chick lit, as a site for the elaboration of new forms of womanhood in post-Apartheid South Africa and through an analysis of the novel Happiness is a Four-Letter Word seeks to discover how new constructs of black female identity in the genre of chick lit disrupt as well as extend earlier representations of female experience in South Africa. The literary aspect of this research is essentially a genre study that attempts to identify how we recognize genre. Chick lit was initially read as a homogenously white normative genre, it was imagined, theorized and researched through the western gaze to the exclusion of other races and classes. This research rejects this essentialism of gender and as such recognizes that when addressing gender in Africa not only race and class need to be contextualized but further historical and cultural contexts are fundamental when constructing the black woman’s subjectivity. Postfeminism is understood as a modern social sensibility declaring that women are ‘now empowered,’ and celebrating and encouraging their consequent ‘freedom’ to return to normatively feminine pursuits. There is a growing field of research around postfeminism and chick lit pertaining to black African women and this is where this research locates itself. By positioning existing western literature, on chick lit, in dialogue with scholarship around chick lit in Africa, a transnational analytic and methodological approach to the critical study of chick lit and postfeminism can be made. Chick lit signals a transition for black women living in post-Apartheid South Africa, one of upward social mobility. This research looks at the contradictory space that black middleclass women occupy in this transition. There is a spectral ‘other’ that restricts black women in fully expressing their agency in the private sphere despite the progress made for women on a national scale. This I have called ‘the Ghost of the Township.’ I explore the extent to which the narrative opens up alternative avenues for writers to represent women’s interests. The author, Cynthia Jele, like other authors writing chick lit about black African women, illustrates how women writers can rethink and reposition the roles of women as they continue to live in patriarchal societies that marginalize and oppress them. In this research, I endeavor to explore if and how these new roles for women create contradictory zones for women by at once empowering and oppressing them. I also ask to what extent things have changed for black women and examine the effects of these changes. / XL2018

Student Number: 9603346N. Master of Arts in Translation. School of Literature and Language Studies / This research focuses on the translation of the South African Broadcasting Corporation’s (SABC) news bulletins from English into Sotho languages, particularly Sepedi. The main aim of this study is to analyse the strategies, methods and approaches used by the translators. The study also tests Stephen Maphike’s 1992 hypothesis which states that the news translators translate literally or word for word, instead of translating conceptually. In order to achieve these aims both the English and Sotho versions of the news were recorded over a period of approximately two weeks, from 22nd September to 5th October 2003. The study falls within the framework of Descriptive Translation Studies, and the analysis is based on translation theories and strategies proposed by authors such as Mona Baker (1992), Peter Newmark (1991), Christiane Nord (1991 & 1997) and Gideon Toury (1980). The conclusions drawn regarding the appropriateness or otherwise of the strategies used are intended to increase an awareness of the problems involved and the solutions available to translators.
