Magister Psychologiae - MPsych / The study made use of cross-sectional design that compared the performance of younger children (6- to 7-year-olds) with that of older children (12- to 13-year-olds) on various measures of executive function. Within this, it made use of a natural experimental design, with children exposed to alcohol as the experimental group and non-exposed children as the control group.

Magister Educationis - MEd / South Africa in the past-apartheid era has undergone a series of curriculum changes that collectively have not yet yielded the desired results. Evidence of this is to be found in the continued low pass rates and poor performance in the annual National Senior Certificate (Grade 12) examinations, including the subject English as a First Additional Language (EFAL). Apart from language policy considerations, reasons related to the teaching approach used in EFAL may have a bearing on the results.The Revised National Curriculum Statement (RNCS) recommends the use of a text-(genre) approach, alongside a communicative approach, to the teaching of languages in schools to replace the old content-based methods with their aims and objectives. While the old curriculum did advocate communicative language teaching, the addition is a text-based approach. This study focuses on investigating the various approaches teachers employ in the teaching of English writing and specifically seeks to identify the extent to which a text-based approach is realized in the teaching of EFAL in Grade 9 in two schools in the Western Cape. The study does so, amongst other ways, by analysing the various texts learners are exposed to in English lessons and taking note of how teachers introduce and negotiate the different stages of writing. This study uses genre theory and Systemic Functional Linguistics (SFL) in combination with social constructivist approaches to language learning. This theory is based on the premise that language is functional and cannot be detached from the social context of the learner.A qualitative research paradigm is used and the study is underpinned by interpretive theory.According to Richards (2003), qualitative research is the study of human action in its natural setting in the context of people’s daily lives. In this case the school classroom has to function as the natural setting. The qualitative data collection instruments for this study include interviews,(particularly open-ended interviews), classroom observation schedules and audio recordings. The teaching processes in the classroom and interview sessions are recorded.The research participants for this study were two qualified English teachers. Secondly, samples of notebooks including class exercises of a selected numbers of learners of English Language in Grade 9 were collected for analysis with regard to the implementation of a text-based approach.The findings revolve round the themes derived from the analysis chapter, and are expected to provide ways of promoting the teaching of English using this approach. They reveal that the teachers in this study do not have sufficient understanding of the theories that underpin the teaching of writing in the English FAL curriculum. They attend to the use of text-based approach superficially but they apply other teaching strategies in their lessons during the teaching of English as a first additional language. The study concludes by summing up the main findings,and by spelling out some implications for further research.

South Africa is faced by a huge problem of inequality, twenty years after the dawn of independence. Such inequalities have been addressed by policy intervention such as the social security and assistance of citizens through various classes of grants. One of the grants targeting children under the age of 18 years is the child support grant. However there are deserving children who have been left-out of mainstream social security through social exclusion. The study sought to investigate the problem of the social exclusion of children from the child support grant in the Nkonkobe municipality. Through the use of the Basic Needs Approach (BNA) to understand the need for any state/government to promote the social welfare of its citizens, the study took a triangulated research paradigm which used both quantitative and qualitative research approaches to collect data from forty respondents by way of a questionnaire survey. The study found out that, inter alia, poverty remains high in the Nkonkobe municipal area, there is rampant social exclusion in the area, the amount paid for the child support grant is little and that the effects of the withdrawal of the grant when the child reaches the age of 18 are unbearable to the child. Some of the recommendations which the study made in line with improved mainstream social security in relation to the child support grant are that, the government needs to improve information dissemination about grants to the populace, there should be mandatory policies to make sure all citizens have identification particulars, the government should be mobile and take services to the people and there should a consideration to review the amount paid for the child support grant upwards. The researcher is quite optimistic that the study will play a part in improving policy implementation.

The seasonality of wild caught Cape mole-rats was investigated, focusing on endocrine, neuroendocrine and neuroanatomical parameters. The Cape mole-rat reproduces only during the winter rainfall period of the western Cape Province. Interestingly, the gonadal steroid hormones do not show any significant seasonal patterns in either males or females. In addition, the pituitary does not exhibit a reduced sensitivity to GnRH stimulation during the non-breeding season in either sex. Moreover, in the brain the distribution, number and size of GnRH perikarya do not differ with respect to season. Therefore, although only producing young during a specific period of the year, the Cape mole-rat does not appear to be physiologically repressed from reproducing throughout the year. The results of this study imply that the Cape mole-rat is an opportunistic breeder that is reproductively quiescent during the dry season as a consequence of ecological factors such as lack of favourable burrowing conditions and that when opportunities avail themselves following aseasonal rainfall, reproduction may occur. The seasonality and socially induced infertility of the Natal mole-rat was examined via endocrine, neuroendocrine and neuroanatomical investigations. In contrast with the phylogenetically closely related common mole-rat and highveld mole-rat, the Natal mole-rat does not appear to breed seasonally. Post-mortem examination of animals collected revealed pregnant reproductive females throughout the year. A similar scenario is reflected in gonadal steroid concentrations, with no major seasonal differences observed in either males or females. Likewise, pituitary sensitivity to GnRH does not change over season in males or females, and all neuroanatomical parameters investigated remained stable over season in both males and females. Natal mole-rats captured for this study occur in an area with a high annual rainfall, (almost double that of the common mole-rat habitat and one and a half times that of the highveld mole-rat) and the relatively higher rainfall and hence soil moisture content may provide the Natal mole-rat with increased foraging time a result of increased periods over which the soil is optimal for burrowing. Socially induced infertility in the Natal mole-rat appears to be enforced behaviourally as a result of active incest avoidance. The circulating testosterone concentrations were not significantly different in reproductive and non-reproductive males, and likewise oestrogen concentrations did not differ between reproductive and non-reproductive females. Progesterone concentrations were very low in subordinate females, but markedly higher in reproductive females. This is not surprising since the Natal mole-rat is an induced ovulator, thus coitus is required to induce the LH surge that stimulates ovulation. The sensitivity of the pituitary to a GnRH challenge did not differ between reproductive and non-reproductive animals from either sex. No neuroanatomical differences were observed between reproductive and non-reproductive animals of either sex, however, non-reproductive males and females had significantly higher amounts of GnRH in the median eminence, implying that GnRH is synthesized and transported to the median eminence but not released in the portal system to the anterior pituitary. These findings suggest that non-reproductive animals of both sexes are not sterile, but merely sexually quiescent.

The majority of the existing urban areas in South Africa began as colonial centres. This study seeks to evaluate the role the Royal Engineers played in the development of the Cape Colony from 1806 until the acceptance of responsible government by the Cape Colony in 1872. The Colonial State implemented a capital works programme of staggering breadth and scale. During this time South Africa was delineated, urbanised, developed and connected to the world markets. This was achieved via a highly trained and professional military establishment; the Royal Engineers. The role of the Royal Engineers and the legacy of towns, forts and infrastructure are studied in depth in this thesis. British imperial approach to colonial expansion and development in both a spatial and theoretical manner forms the basis of this thesis. The case study covers the Eastern Cape of South Africa. The physical and spatial development of this region are analysed in order to glean any lessons which could be learnt from the approach adopted to colonial settlement. This Study illustrates that a small highly trained group of military engineers had a significant impact on the establishment of early towns and infrastructure in South Africa. They have left a lasting footprint on South Africa’s spatial development and many of the towns and much of the infrastructure is still in use today (specifically the harbours, railways and mountain passes). The Royal Engineers’ approach to development and background training is studied and then reduced to its theoretical approach. This theoretical approach is then analysed in order to glean the lessons history can teach us about development, specifically development on ‘terra nova’. An attempt is made to extract planning theory from historical analysis of developmental elements which worked in the past. The study begins by analysing the background and training of the Royal Engineers and then moves on to assessing the spatial and physical impact their plans had on the development of South Africa. The discussion then moves beyond what the Royal Engineers did to understand how they made it happen; to arrive at a positive theory of planning or to ask when does planning work ? The Royal Engineers were schooled in the sciences and trained to be experts in almost all things; they were the master craftsmen and skilled problem solvers of the era. The training they received at Chatham, is a very early example of professional training; it was comprehensive, high quality and practical. Those who emerged from this training carried out vast public works around the British Empire; they produced very few theories of development but they did challenge ideas. The avant- garde designs of some colonial towns such as Queenstown, Khartoum, Adelaide and Savannah show a desire to improve on settlement forms and to provide design solutions to urban problems. The Royal Engineers adopted a pragmatic approach to development, they initially received a very good scientific academic training, they then learnt by example whilst serving under engineer commanders. As a unit they learnt by observation, experimentation and example. What is striking in their approach is that they saw a problem and simply went about solving it and their solutions were inevitably physical structures and infrastructure. / Thesis (PhD)--University of Pretoria, 2011. / Town and Regional Planning / unrestricted

Thesis ( MPH.) -- University of Limpopo, 2022 / Background Multidrug-resistant tuberculosis (MDR-TB) has recently resulted to be in an emergence state globally and this of constitute a big challenge for TB control and the goals of the World Health Organization’s End TB Strategy. Aminoglycosides (AG) were often used as part of treatment of life-threatening illnesses such as MDR-TB for decades, however their adverse effects are widely described and hearing loss is one of the major side effects. The risk factors for hearing loss in patients treated with AG include the dose and duration of AG, infection with human immunodeficiency virus (HIV), older age and persons exposed to a high level of noise while the damage can be total and permanent. Severe hearing impairment has been reported to occur among patients treated for MDR-TB with injectable drugs, especially among the elderly and patients infected with human immunodeficiency virus, however, Bedaquiline containing regimens have demonstrated improved outcomes over injectable containing regimens in the long-term treatment of MDR-TB. Methods The objective of the current study was to investigate the burden of hearing loss amongst MDR-TB patients on bedaquiline at Zithulele Hospital in Eastern Cape Province. Therefore, the current study followed a quantitative retrospective approach using simple random sampling to select MDR-TB patients treated with bedaquiline and having a baseline audiogram be the initiation of treatment. The data was captured in a Microsoft Excel spreadsheet and then transferred to Statistical Package for Social Sciences (SPSS) Version 20 for data analysis in which categorical variables were presented as percentages and frequencies, while continuous variables was presented as mean, median and standard deviation lastly, comparison of categorical variables was done using a Chi-Squared test, whereas continuous variables were compared using a t-test. P-value of <0.05 will be considered significant. Results The mean age for the participants was 39.2 years with standard deviation of 11.8 and there was no statistical significance difference between the age groups (p value = 0.178). There no was a statistical significance difference between the employment status (p value = 0.794), previous use of injectables (p value = 0.360) and type of hearing of loss (p value = 0.536). Majority of the MDR-TB patients on bedaquiline did not have hearing loss at 67% while those who had gradual hearing loss and sudden hearing loss were 26.8% and 6.2% respectively. There was no statistical significance difference between males and females in both the right and left ears, however, the right ear results appeared to be slightly worse than the left ear results. It was found that both males and females had a high frequency hearing loss in the left ears of 26.8% and 22.2% respectively as compared to the right ears with of 25.9% and 1.6% respectively. The was a statistical significance difference between the age groups in both ears for hearing loss at p-value <0.001. The overall prevalence of hearing loss was found to be 32.9% and hearing loss at 20dB or more loss at any frequency was low at 11.9% while hearing loss at 10B or more loss at any frequency was the highest at 32.9% followed by loss response at 3 consecutive frequencies at 26.2%. Hearing loss was increasing with increasing age from 8.3% in age group and age was significantly associated with hearing loss as older patients were 2.2 times more likely to have a hearing loss at a degree of 20dB and 4.4 times more likely to have a hearing loss at a degree of 10dB. Previous use of injectables was also significantly associated with hearing loss as patients who used injectables previously were 11.5 times more likely to have a hearing loss at degree of 10dB, 5.6 and 11.3 times more likely to have a hearing loss at loss response at 3 consecutive frequencies and overall hearing loss respectively. Conclusion South Africa has a high burden of drug-resistant tuberculosis (DRTB) and until recently, ototoxic aminoglycosides were predominant in treatment regimens. Drug resistant TB treatment with bedaquilines caused clinically and statistically significant deterioration of hearing loss in patients, most prominently at high frequencies. Although public health interventions to prevent hearing loss have been deemed cost effective and have meaningful individual and economic implications, hearing loss and its prevention consistently receive inadequate attention as a global public health priority. Despite the serious impacts of hearing loss, little is known regarding prevalence of ototoxic hearing loss after treatment for DR-TB. Therefore, when the use of injectable ototoxic medications is unavoidable, audiological ototoxicity monitoring is essential to optimise hearing-related outcomes.

A descriptive survey to identify factors influencing relapse of psychiatric outpatients in the rural communities of the Eastern Cape was undertaken. A questionnaire was used to collect data from family caregivers who were relatives of psychiatric patients receiving their monthly medications from two rural clinics. Data were analysed using the Statistical Package for Social Sciences (SPSS) version 17. A total number of 92 family caregivers participated. Respondents reported side effects of psychotropic drugs, poor family role, poor referral system, lack of home visits, non-compliance and stigmatization as major factors contributing to relapse of psychiatric outpatients. Active involvement of caregivers in follow up care of their relatives is effective in fostering collaboration between the psychiatric hospitals and patients with the common goal of relapse avoidance. It is recommended that adequate provision of resources in conjunction with health education is effective in enhancing collaboration towards prevention of relapse in psychiatric patients. This would promote team work among patients, caregivers and health care providers. / Public Health / M.A. (Public Health)

This study focused on the impact of climate change and adaptation on small-scale cattle and sheep farming in the Eastern Cape province of South Africa. Using information from 500 livestock farmers between 2005 and 2009 farming season, three methods of analysis were used to determine impacts of climate change and adaptation. They were Principal Component Analysis (PCA), Binary Logistic Regression Model (BLRM) and Heckman Probit Model (HPM). Findings revealed that cattle production decreased during the study period 2005 to 2009. Preliminary descriptive statistics results indicated that farmers had different perceptions on climate change and adaptation measures between the periods 2005 and 2009. Further analysis using PCA showed that the different perceptions could be grouped into: (i) drought and windy weather patterns; (ii) information and adaptation; (iii) climate change extension services; (iv) intensive cattle and sheep production; and (v) temperatures. The results of the BLRM indicated that the most significant factors that affected climate change and adaptation were: (i) non-farm income per annum; (ii) type of weather perceived from 2005 to 2009; (iii) livestock production and ownership; (iv) distance to weather stations; (v) distance to input markets; (vi) adaptation strategies and (vii) annual average temperature. From the HPM the results indicated that marital status, level of education, formal extension, temperatures and the way in which land was acquired, significantly affected awareness on climate change. Variables that significantly affected adaptation selections were gender, formal extension, information received on climate change, temperatures and the way in which land was acquired.It was concluded that in the area of study, change in climate was already perceived by small-scale cattle and sheep farmers. Households that perceived differences in seasonal temperatures during the survey period were less likely to adapt to climate change. Having access to extension services increased the likelihood of adaptation to climate change. Information on climate change to improve livestock production appeared to play a significant role in the selection of adaptation measures. The recommendation was that government should consider cattle and sheep farmers’ perceptions on climate change when deciding on programmes for cattle and sheep production. It further suggested that the most significant factors that affected climate change, adaptation, and awareness and adaptation selections be considered when adaptation programmes are planned. / Agriculture Animal Health and Human Ecology / D.Phil.

The thesis deals with the difficulties concerning alcohol use and misuse among Coloured farm workers within the heart of the wine industry in South Africa. The current extent of alcohol use and misuse in the rural areas of the Western Cape Province is commonly referred to as the legacy of the dop system. The dop system was a legislative practice whereas farm workers were provided with small portions of cheap wine throughout the workday. The practice was racially targeted towards Coloureds and thus contributed to the creation of a dependent labour force and extensive alcohol-related difficulties among Coloured farm workers. The dop system was formally abolished in 1961 but the practice proceeded into the 1990s. Alcohol related difficulties do however tend to continue without signs of change. The main purpose of the study is to investigate how current difficulties of alcohol use and misuse affect children’s life outcome and educational opportunities. It has also been important to investigate various aspects of living and working conditions in the farm villages that may be linked to alcohol issues. Another aim is to determine contributing factors to the continuance of alcohol use and misuse despite the abolition of the dop system. The work has been conducted according to the method of oral history theories in order to provide a bottom up approach, thus allowing the perspectives and the stories of the farm workers themselves to come forth. Coloured farm workers in the region are largely affected by socio-economic concerns and uncertainty in regards of labour. Inexpensive and readily available alcohol in illegal liquor outlets, so-called shebeens, is a driving force to the consumption of alcohol. Farm workers are partly isolated upon the farm villages and commonly have limited opportunities of unionizing. This makes it crucial to let the farm workers and their families express how alcohol difficulties are manifested in and affecting their daily lives.
