M.Sc. (Geology) / The Witwatersrand Supergroup is host to a number of auriferous and uraniferous conglomeratic reefs, which have been extensively exploited along the Witwatersrand Basin margins. The current study investigates the Vaal Reef, in the Klerksdorp gold field with particular focus on conducting a geometallurgical characterization of the ore which may ultimately enhance the recovery of gold and uranium and our understanding of how the ore responds to processing. Six samples were collected from AngloGold Ashanti’s Moab Khotsong mine and prepared for a chemical and mineralogical deportment study. These samples were milled and crushed down to 80% passing -75μm and processed for head chemistry assays, grading analysis as well as heavy liquid separation analysis as part of the chemical deportment. The samples were also submitted for gold cyanide, acid uranium and diagnostic leach tests.....

This study examines the factors that contributed to the failure of retrenched Telkom workers to start and run successful businesses after the company had provided them with start-up capital and also funds for training. Many of the factors contributing to the majority of Telkom retrenched employees not establishing businesses will be identified and recommendations that companies could implement in the future to limit the failure of businesses of retrenched employees will be made. The study was descriptive, exploratory and qualitative in nature. Semi-structured interviews and a survey questionnaire specifically developed for this study were used to gather data. The study was conducted on ex-employees of Telkom residing in and around the townships and suburbs situated on the western side of Johannesburg (Mogale City, Randfontein and Soweto). Telkom provided retrenched employees with funds to attend external training so that they could be equipped to start and run their own businesses. Subsequently, Telkom also provided start-up capital so that these employees could start small businesses after they had left the company. Although the funds were provided, most employees did not utilise them to start their businesses and the few that did access the funds and start businesses experienced the failure of their businesses within a very short period of time. Three major issues of concern were identified: many of these ex-employees did not utilise the funds that were allocated for training; many did not make use of the start-up capital and the majority did not start businesses. The study investigated the following issues: a) Why the retrenched employees did not make use of the funds allocated for training b) Why the ex-employees did not make use of the start-up capital c) Why the ex-employees did not start businesses d) Of those that did start businesses, why did they fail within such a short period of time? The findings of the study confirm that most of the retrenched employees did not access either the training or the start-up funds. Detailed reasons for why the funds were not made use of are given and recommendations are also made for what the company should do in future if deciding to embark on a similar exercise. / Business Management / M.

M.Ed. / Many mothers enter the labour force because of the need for workers and the financial position of the family which is worsening in these highly inflationary times. Although this might solve some financial problems in the family, it creates other problems, for instance child care. The question now arises as to how the adolescent daughter will form her own identity if her mother follows a career. It is clear that the working mother has no easy task. Besides her career, she also has her children, her husband and a household to take care of. Furthermore, she has the task of helping her adolescent daughter with the formation of her own identity. Two variables have been identified: * the relationship between mother and daughter * the identity formation of the adolescent daughter. An English and Afrikaans questionnaire was compiled based on these variables. The questionnaire was answered by 1086 girls and boys (Afrikaans, English and other language groups) between the ages of 12 and 18. Mothers were grouped into three categories, namely full time, part time and non - working mothers. The most important findings of this study are the following: * Working mothers develop a relatively better relationship with their adolescent children in comparison with non - working mothers. * The relationship between mother and daughter develops relatively better than that of mother and son. * Younger adolescent daughters develop a relatively better relationship with their mothers than older adolescent daughters. * Afrikaans speaking adolescent daughters develop a relatively better relationship with their mothers than adolescent daughters of other language groups. Guidance to working mothers of other language groups seems to be necessary. * The formation of the identity of adolescent children of working mothers develops relatively better than those of non working mothers. The averages of all the girls are quite high, which indicate that the mother - child relationship and the identity formation of the adolescent daughter develops well, irrespective of the mother's career.

The primary aim of this dissertation is to map the geology of the East Rand Basin accurately by creating a 3D model. This was done by using borehole data from the National Groundwater Archive Geodatabase, which the Department of Water and Sanitation collected, and the average depths derived from the literature. Triangulated irregular networks (TINs) and digital elevation models (DEMs) surfaces were created from these data points to determine the depths for areas with no borehole data. Using these surfaces, three methods were used to create three main models. These models were then compared to one another, other geological maps and cross-sections to determine the most accurate and practical model of the three. It was found that the quality and quantity of the data from the National Groundwater Archive Geodatabase were not sufficient for these models; therefore, the results and accuracy of each layer was questionable. This dissertation found that these methods can be used for basic geological studies if the data are of the same quality and quantity. However, if the data are more evenly distributed and higher in quantity, these methods can be used to create more accurate models. Furthermore, the use of commercial software was recommended in this study. The reason for recommending these tools is that they have been specifically designed to create geological layers from boreholes within the ArcGIS software. These tools also allow the user to create cross-sections within ArcGIS. / MSc (Geography and Environmental Management), North-West University, Potchefstroom Campus, 2015

De nombreux commentateurs se sont aventurés sans succès à qualifier d'égoïsme ou d'altruisme les travaux de Platon et d'Aristote sur l'amitié. Ce questionnement est pourtant le fruit d'une intuition valable : il serait intéressant de réactiver notre compréhension des théories de l'amitié de Platon et d'Aristote afin d'évaluer si elles répondent de manière satisfaisante à nos soucis contemporains en matière d'éthique des relations interpersonnelles. Ce mémoire a comme objectif d'entreprendre une lecture et une interprétation en profondeur de ces théories, spécifiquement à travers le Lysis et l'Éthique à Nicomaque, puis d'aborder les principaux problèmes soulevés par les théories contemporaines qui se réclament de l'altruisme ou de l'égoïsme afin de trouver les outils et les concepts qui nous permettront de clarifier notre compréhension des premières. Nous verrons en fin de parcours comment les théories antiques se rapprochent de ce que nous connaissons aujourd'hui comme l'égoïsme normatif, mais seulement en apparence. Les théories antiques formulent une éthique des relations personnelles complètement originale, qui part toujours de la perspective individuelle mais qui cherche à s'étendre vers l'extérieur, vers un souci authentique ou noble de ses amis. Elles reconnaissent et acceptent la part d'autoréférentialité inhérente à toute bienveillance envers les personnes chères, tout en balisant cette autoréférentialité, délimitant ainsi un modèle de ce qu'est l'amitié réussie, ou pour ainsi dire, un modèle de ce qu'est une relation personnelle éthique.

During the 1980’s the non-profit organisation RAND Corporation conducted the two-year Medical Outcomes Study with the goal of creating a comprehensive medical questionnaire. The resulting 116-item questionnaire measures health related quality of life (HRQoL) topics such as physical, mental and general health. The questionnaire is available as a free resource on their web page. SF-36, which contains 36 of these questions, is distributed for a fee by the US company Quality Metric Inc. The company has translated the questionnaire into several languages, including Swedish, and has also taken license for the translations. Registercentrum sydost has made a new Swedish translation of the same questions as in the SF-36. This survey is called RAND-36 and is license free. Because Quality Metric Inc has taken license for its Swedish translation, the surveys are similar but not identical. This study aims to compare the aforementioned HRQoL-instruments to determine whether it is possible to replace the licensed questionnaire SF-36 with the license free RAND-36. The distribution of items with response options according ordinal scale were compared with Mann-Whitney U-test. The test yielded a significant difference for eight items in the measure PF(physical functioning), MH(mental health), VT (vitality) and GH (general health perceptions). The distribution of items with response options according dichotomous scale were compared with X2-test. The test yielded significant difference for an item in the measure RE (emotional role functioning). The reliability of questionnaire was compared with ordinal alpha. In the selection the reliability between MH and VT is equivalent. The biggest difference between the surveys is the measure RP (physical role functioning) where the RAND-36 meets the requirement that the measure can be used for reliable conclusions on the individual level, which is a condition that SF-36 can’t met. The probability of entering an answer, given the respondent's ability, was compared with Rasch analysis. Wald's test gave DIF between most items within the measures PF, MH, VT and GH.

Magister Scientiae Dentium - MSc(Dent) / The Gauteng province is divided into 5 districts each of which have a public based oral health programme. Each district provides oral health treatments such as dental extractions with treatment of pain and sepsis, preventive dentistry, simple restorations, removable prosthodontics (complete and partial dentures) and minor oral surgery in selected facilities. The main treatment modality in most government based dental clinics is dental extractions (Department of Health, 2003). This indicates the poor status of the population’s teeth. Dental caries is a condition that can be prevented if adequate efforts are made to practice preventive dentistry. Preventive dentistry has been a treatment modality that has been practiced poorly or almost completely ignored in several oral health facilities for many years. This neglect could be due to several factors such as in adequate knowledge regarding preventive dentistry procedures, poor attitude towards preventive dentistry, lack of motivation, or lack of resources (Clark, 2011). The purpose of this study is to determine why preventive dentistry has been neglected for so many years.

Student Number: 0216613T Master of Arts in Journalism and Media Studies. Faculty of Humanities and Social Sciences / This research examined the notion of liberal journalism in South Africa during apartheid as practiced at the RDM. It considered whether the paper, facing government scrutiny and restrictive laws, adhered to the principals of liberal journalism and how successfully it did so. The 1976 Soweto Uprising was used to assess the newspaper’s performance and the merits of arguments for and against the notion of it being a successful example of a liberal newspaper. Content analysis and interviews with RDM staff members, was used to assess the paper’s conduct. These primary sources were examined in conjunction with available literature and criticisms against the English press and RDM presented in testimonies at the TRCMH to assess the paper’s reportage and how valid criticisms against it were. The researcher concluded that, due to serious shortcomings, which included its reporting of the uprising, the RDM was not a successful liberal newspaper.
