The use of the digital school library depends on many factors, including end-users‘ acceptance. The issue of designing information systems that will be used appropriately is growing and thus user acceptance of new technology is now receiving much attention by researchers. Without acceptance, discretionary users will seek alternatives, while even dedicated users will most likely manifest dissatisfaction, negating many, if not all, the presumed benefits of the digital library. Whereas the traditional focus of digital libraries has drawn research on technological developments, there is a call for user-focused research. This study sought to identify the dynamics of elementary children‘s (11- to 13- year olds) decision-making in the context of accepting or resisting making use of digital school libraries at Crawford Preparatory Pretoria School in Gauteng. To be accepted, the digital library must satisfy basic usability requirements and be perceived as useful by the children. The constructs of the Technology Acceptance Model, perceived ease of use and perceived usefulness were used to generate an understanding of acceptance of the digital school libraries. The study adopted a quantitative case study research approach to compare the empirical data and the TAM theory. Data triangulation of a wide range of data collection methods, including observation, questionnaires, focus groups and tasks given to the children to work on using the International Children‘s Digital Library was analysed. The findings revealed that, just like adults, children make decisions regarding accepting and using the digital school library based on how easy it is to use and how relevant it is to their needs. The study recommends that software designers, teachers and librarians work with the children when designing digital school libraries to ensure that their acceptance factors are taken into consideration when designing for them. / Information Science / M.

This dissertation evaluates the vision of empowering African elites iQ the International Church of Pretoria and suggests the ways to successfully train and empowers these Africans for the positive socio-political transformation of Africa. Such Christian empowering is so complex that it has to deal with the spiritual, psychological, intellectual and/or technical and socio-political aspects of the life of the trainee. After describing the problems that prevent these elites from behaving adequately and the portrait that can facilitate the successful selection of their trainers the dissertation proposes the guidelines of the empowering programmes for different elite groups. In the main the curriculum comprises a four-level conversion component for proper Christian life, and a psychotherapy empowerment coupled with horizontalisation for their liberation from psychological and socio-political evils, and a programme for the selection and the training of the spiritual leaders of the African elites. / Christian Spirituality, Church History and Missiology / M.Th.

South Africa has a low throughput rate in the public higher education sector which leads to severe skill shortages that are urgently required by the country. In particular, the financial skills shortages are severe, especially those of accountants and chartered accountants. Keeping in mind the vastness of the University of South Africa’s (Unisa’s) market share of accounting students in South Africa, it is important to understand the distinct challenges related to retention and throughput of students pursuing an accounting qualification at an open distance learning institution such as Unisa. If one considers the landscape of accounting education in South Africa, the unique challenges faced by accounting students at Unisa and the recent scholarly addresses on retention and throughput of distance education students, as well as the disadvantaging factors with which Unisa students are faced, this study contributes to the theoretical comprehension of students’ retention and throughput rates in accounting education at postgraduate level. The focus of the current study was mainly on non-academic factors affecting the performance of accounting students at postgraduate level, since much research has already been done on academic factors that affect the performance of accounting students. Many studies are focussed on students at undergraduate level; therefore, in this study, postgraduate students studying towards becoming a chartered accountant were chosen. / Financial Accounting / M.

Background: Group B streptococcus (GBS) is regarded as one of the most important causes of maternal and neonatal morbidity and mortality in many parts of the world. GBS recto-vaginal colonization is important in the health of a mother and her neonate, especially in developing countries. Maternal vaginal colonization with GBS at the time of delivery can cause vertical transmission to the neonate. Multilocus sequence typing (MLST) is a technique used to characterize microbial isolates by means of sequencing internal fragments of housekeeping genes and has the advantage of reproducibility and has been shown to correlate with the other typing techniques and thus has emerged as the standard for delineating the clonal population of GBS. The study aimed to investigate the epidemiology of GBS colonization among pregnant women and their neonates, and to characterize the isolates by multilocus sequence typing technique at Dr George Mukhari Academic Hospital, Pretoria. Methodology: A total of 413 pregnant women who visited the antenatal clinic were recruited and screened. Participants were interviewed using a questionnaire to gather demographic and other relevant information such as history of current pregnancy, previous miscarriages and still births. Samples from maternal rectum and vagina as well as neonate ear and umbilical cord were taken for culture using colistin and nalidixic acid (CNA) blood agar and incubated for 24-48 hours. If negative after 48 hours, Todd-Hewitt broth was subcultured after 18-48 hours onto sheep blood agar. Multilocus sequence typing (MLST) was used to characterize seven group B streptococcus isolates collected at Dr George Mukhari academic hospital. Fragments of seven housekeeping genes were amplified by polymerase chain reaction (PCR) for each strain and sequenced. CLC bio software (Inqaba biotech, South Africa; Pretoria) was used to analyse sequenced loci and UPGMA dendrogram was constructed. Results: The colonization rate for GBS in pregnant women and their neonates was 30.9% and 0%, respectively. A higher proportion of GBS were isolated from the rectum (37.9%) as compared to the vagina (20.6%). Most socio-economic, demographic and obstetric factors analysed were not significantly associated with.GBS colonization. On 128 positive samples, the results of Todd-Hewitt enrichment broth and direct plating method using CNA were compared. A total of 45.3% of colonised were positive on direct selective agar (CNA); an additional 54.7% samples were recovered from Todd-Hewitt broth. Three genes (adhP, glnA and tkt) were sequenced successfully for six samples (1, 2. 4,6,12 and 65). The UPGMA tree with 1000 bootstrap showing the relationship between six samples was drawn.Conclusion: This study revealed that pregnant women of all ages are at risk of group B streptococcus colonization. Group B streptococcus was common among pregnant women at Dr George Mukhari Academic Hospital. No socio-economic risk factor was associated with group B streptococcus colonization. Results confirm that the combination of Todd-Hewitt broth and CNA agar plate is a time saving and sensitive method. The allelic profile, characteristics such as G+C (guanine+cytosine) content and dN/dS ratio were not analysed because of the smaller sample size used in this study, which shows that the MLST method was unsuccessful in this study. The UPGMA tree based on differences in consensus of the isolates showed that all group B streptococcus isolates are clustered and descend from a single node. / Life Sciences / M.Sc. (Life Sciences)

Various potential modes of interpreting the urban space in the inner city of Pretoria is evaluated in this study with the purpose of expanding discourse around spatial production in the city. Production of meaning through formal and structural means produced a city that served as administrative capital and ideological base for Afrikaners until the arrival of a democracy in 1994. The contemporary urban space is produced by people through everyday life, as theorised by Henry Lefebvre, rather than through formal means such as name changes. This study evaluates the way that identity and belonging is created by referring to everyday life practices, rhythmanalysis and daily activities as performances. Urban space is evaluated from a phenomenological perspective through the eyes of an artist and resident and expressed in an art exhibition. The way artists Julie Mehretu and Franz Ackermann dealt with urban space in their art is also referenced. / Art History, Visual Arts and Musicology / M.A. (Visual Arts)

A child's early years are vital for development. The first few years of life is a period of rapid physical, mental, emotional, social and moral growth and development. This is a time when young children acquire concepts, skills and attitudes that lay the foundation for lifelong learning. During this time, parents are the primary influence on a child’s development and learning. The more parents are involved with their children, the more positive learning and general life outcomes occur. Different factors have been linked to children’s readiness to learn as they enter school. These include family characteristics such as the income level of the child’s household, parent education, and family structure. Other experiences in the home and community also linked to children’s readiness to learn include the quality of their relationships with parents, educational activities at home, and opportunities to participate in recreational or educational activities. Research has shown that poverty in early childhood can prove to be a handicap for life. Studies have revealed that many children under the age of five, living in poverty, annually fail to reach their full cognitive and social potential and do not have the necessary knowledge, skills and attitude to engage effectively in formal schooling once entering Grade 1. In the light of this, parents are in a key position to establish a suitable environment and to provide experiences during the early childhood years, whereby their young children can grow and develop to reach their fullest potential. This study is aimed to determine the way parents from disadvantaged backgrounds perceive their role, in their children’s early development and preparation for school. A selected group of parents of preschool children from disadvantaged communities in an area northeast of Tshwane participated in focus group discussions. Through the information obtained from the study, crucial limitations and needs regarding parenting and school preparation were identified. Based on these findings, the necessity for an effective and helpful parental guidance and intervention programme for these disadvantaged communities were recognized. If parents become more knowledgeable about early childhood development and school readiness, by expanding and improving their parenting skills, they might largely improve the development and learning abilities of their preschool children. It is therefore recommended that this study forms the foundation in the development of an intervention programme, which addresses the needs of these parents and provides support to equip them in their roles, in preparing their preschool children for school. / Early Childhood Education and Development / M.

Food is one of the main routes by which xenobiotic (synthetic) chemicals enter the body of man and wildlife. The routes could be from wrappers in which the foods are presented with possible transfer of the compounds to consumers, hence need for regular screening. The research work is aimed at investigating possible prevalence of phthalate esters in selected foods (cheese, polony and vienna) and their plastic wrappers from commercial stores in Tshwane metropolis. Food samples were purchased from selected stores, taken to the laboratory and stored at 4oC until analysed. Analysis was done by soxhlet extraction while determination and quantification of phthalates was carried out using Gas Chromatography-Flame Ionization Detection (GC-FID). Quality assurance of the process was by standard addition of the phthalate ester standards. Results obtained revealed good chromatographic separation of the analysed esters which ranged from 5.55 min for Dimethyl phthalate (DMP) to 8.96 min for Benzylbutyl phthalate (BBP). Instrumental detection limit of the esters varied from 0.03 - 0.05 μg/kg. The percentage recovery of the phthalate esters ranged from 75 – 90% from spiked cheese samples; 33 – 66% from spiked polony samples and 69 – 99% from spiked vienna samples. These recoveries are quite acceptable and applicable to the analysis and quantification of the compounds in the samples with the exception of Dibutyl phthalate (DBP) (33%); DMP (34%) and BBP (46 %) in polony samples. Results from chromatographic quantification revealed the absence of or non-detection of most of the analysed phthalate esters in the selected food samples. However, level of 0.031 μg/kg of BBP - 0.816 μg/kg of DMP were obtained in some of the analysed samples. / Environmental Sciences / M.Sc. (Environmental Science)

In English / The purpose of this study was to establish factors affecting the participation of men working in the informal sector economy of South Africa in HIV counselling and testing (HCT) or voluntary counselling and testing (VCT). This includes the exploration of reasons for acceptance and non-acceptance of HIV testing, knowledge and perceptions about HIV testing and behaviours and attitudes towards HIV testing. Data was collected through a structured questionnaire and a sample of fifty (50) men was purposively selected. It was found that the reasons for acceptance of HIV testing are satisfactory and reasons for non-acceptance are still a concern, and that several issues such as education about HIV testing and HIV in general still need to be addressed. Most of the respondents had undergone testing for HIV, but there is still a stigma attached to HIV testing. / Sociology / M. A. (Social Behaviour Studies in HIV/AIDS)
