The problems existing at the School of Process and Mechanical Engineering may be linked to that fact that its organisational culture has not been diagnosed. Some of the issues facing the line managers at the School of Process and Mechanical Engineering are the low morale of staff; high staff turnover rates and tension within the School of Process and Mechanical Engineering. In addition, with the proposed merger between TWR, Rand Afrikaans University and Vista University, the current culture may need to change. Hence, the core focus of this study was to identify the existing organisational culture within the School of Process and Mechanical Engineering with a view to assist line managers in enhancing its effectiveness. The Competing Values Framework, together with the Organisational Culture Assessment Instrument (OCAI), was used to diagnose the culture within the School of Process and Mechanical Engineering. It was found that within the School of Process and Mechanical Engineering at present, the dominant culture is the hierarchy type culture and the preferred dominant culture should be the market type culture. The hierarchy type culture focuses on internal maintenance with a need for stability and control whilst the market type culture has an external focus with a need for stability and control. It was recommended that the School of Process and Mechanical Engineering change its current hierarchy culture towards the market type culture. The study was concluded by providing recommendations in order to facilitate a smooth transition from a hierarchy type culture to a market type culture. / Thesis (MBA)-University of Natal, 2003.

AIM OF THE STUDY - The general aim of the study is to design a selection test battery that can be used to screen students for the diploma courses in Management practice and Personnel management before the enrolment at the Witwatersrand Technikon. The specific aims are twofold: namely theoretical and empirical. The theoretical aim is firstly to give some perspective as far as the use of psychometric tests in the selection procedure, and secondly to give an overview of those factors that affect academic performance. The empirical aim consists of three objectives: To determine which factors are significantly related to academic performance of first year students for the Management practice and the Personnel management courses, respectively. To determine those factors that reflect a significant difference between the successful and unsuccessful students in both diploma courses. To develop a profile of the successful and unsuccessful groups' test performances for selection purposes. METHOD OF INVESTIGATION - A study of the relevant literature was undertaken concerning the role of psychometric tests in the selection procedure, as well as the effect of different cognitive and non-cognitive factors on academic performance. As a result of the limited number of first year students in these two courses, the total first year student group was involved in this study. The psychometric tests used in this study are the 19 Field Interest Inventory, the Structured Objective Rorschach test (SORT), The Survey of Study Habits and Attitudes (SSHA), the 16 Personality factor questionnaire {16PF), the subtest Mental Alertness of the Intermediate Battery and the Academic Achievement Battery. RESULTS OF THE MULTIPLE REGRESSION ANALYSIS - The test that shows the highest correlation with academic performance for both groups is the 16PF. In the case of the Management practice group, the correlation is 0,62 and for the Personnel management group, the correlation is 0,77. The Management practice group also reflected correlations between academic performance and previous performance (r=0,48) and between academic performance and interest (r=0,63). On the other hand, correlations were also found between academic performance and the SSHA ( r=O, 5 9) and between academic performance and mental alertness (r=0,42) concerning the Personnel management group. The 16PF therefore showed the highest correlation with academic performance for both groups. As a result of these findings and the relatively small population group used in this study it was decided, for the remainder of the investigation to combine the two groups. The new combined group was then subdivided into a successful and an unsuccessful group. RESULTS OF THE PROFILE ANALYSIS - The successful group obtained average scores which were higher than those of the unsuccessful group on eight factors of the 16PF. These eight factors are: A(Sociality), B (Intelligence), E(Dominance), F(Carefreeness), H (Social venturesomeness), L(Suspiciousness), N(Astuteness) and Ql(Radicalism). Of these eight factors, the differences for the last three are very insignificant. The unsuccessful group obtained higher average scores on the remaining eight factors but once again these differences are insignificant. RESULTS OF THE t-TEST - Significant differences were found between the successful and unsuccessful groups with regard to factors A(Sociality), B(Intelligence) and F(Carefreeness) on the 0,01-level while significant differences on the 0,05-level were obtained on factors E(Dominance) and Q3(Self-control). These results can be summarised as follows: * The successful group• is definitely more social, in other words more outgoing, carefree and more participative than the unsuccessful group. * The successful group has a greater mental ability than the unsuccessful group, is more independent and shows more enthusiasm. * The unsuccessful group shows a greater degree of self-control than the successful group with the result that they experience more anxiety in the process. According to this study, personality factors seem to play a more significant role than any other factors as measured in this particular case. Biographical data should also be considered in a study like this as this might possibly lead to other factors that influence academic performance. / Skripsie (MA)--PU vir CHO, 1987

M.Cur. / Advances in medical technology have led to major technological developments in the field of neonatal care. Over the past three decades there has been increasing concern about noise levels in neonatal intensive care units. The experience of working in a neonatal intensive care unit and exposure to high noise levels of such a unit prompted the researcher to investigate the sources of noise further and to explore ways of reducing or preventing the occurrence of noise. After conducting an extensive literature review, a systematic measurement of noise levels in a neonatal intensive care unit was undertaken. The following findings emerged:- There is a considerable level of noise in the neonatal intensive care unit and this noise persists throughout day and night. The sources of noise are mainly environmental, equipment, personnel and patientrelated. It was significant to observe that neonatal personnel can contribute to the reduction or prevention of high noise levels in the unit. Guidelines for neonatal personnel have been developed to this end. It is hoped that this study will make a contribution to the creation of a more conducive neonatal environment.

D.Cur. (Professional Nursing Science ) / Curriculum evaluation of Community Nursing at the Ann Latsky. Bona Lesedi and Coronation Nursing Colleges was done on the basis of Stake's curriculum evaluation model which was used as point of departure and altered to comply with the specific requirements of the curriculum evaluation of Community Nursing. The purpose of the evaluation was to identify inadequacies in the curriculi and to initiate improvements. Firstly, the intentions of the Nursing Colleges with regard to the Community Nursing curriculum were described. Secondly, certain observations were made' by way of. among other things. questionnaires to enable the researcher to make further delineations. In the third instance. standards were described which is important in evaluating curriculi. The curricular were evaluated on the basis of the details gathered. Lastly. guidelines were laid down to serve as a source for improving curriculi. Observations made included the following: - Students are uncertain of their readiness for community nursing immediately after training. - Only one of the Community Nursing lecturers at the three Nursing Colleges has sufficient clinical experience in Community Nursing. - Sixty four per cent of the clinical practitioners who took part in the study do not fully agree with the objectives set down for practical work in Community Nursing. - Students are generally satisfied with Community Nursing content. - Some of the guidelines set down by the researcher for the improvement of the Community Nursing curricular are: - Management must come to an agreement with. among others. local authorities to enable lecturers to be appointed in a part-time clinical position to improve their clinical experience...

M.Sc.(Geology) / The Mesoarchean Witwatersrand Supergroup is a remarkably well preserved siliciclastic dominated cratonic platform succession located on the Kaapvaal Craton in South Africa. The vast gold resources which have been mined since 1886 make it relevant for study. The study aimed to identify significant provenance shifts throughout the depositional life of the basin which should be reflected in the in heavy mineral populations and the geochemical composition of the siliciclastic rocks. The study identified major changes in the source rock compositions through the basin lifespan and inferred major tectonic events during the life of the basin. It was found that the mechanical effects of sorting in different depositional environments tended to obscure provenance shifts, but with careful evaluation of the various factors in play significant provenance shifts could be identified. It was found that these provenance shifts corresponded closely with major unconformity sequence boundaries identified by Beukes (1995). These major provenance shifts are a record of a major tectonic event during the development of the basin. The Hospital Subgroup records a passive trailing margin, fed by a combination of felsic and ultra-mafic source rocks. Within the Hospital Hill Subgroup, there is a trend of increasing ultramafic components in the source area with increasing stratigraphic height. This trend is believed to reflect progressive unroofing of tonalite and greenstone belt complexes over the life of the Hospital Hill Subgroup. At the base of the Promise Formation a basin wide unconformity is present, which marks a shift from mature shallow marine and outer shelf sediments of the Hospital Hill Subgroup to immature fluvial quartzites for the Government and Jeppestown Subgroups (Beukes, 1995). In addition to the major change in depofacies that was recognised by Beukes (1995), this study found evidence for a shift in provenance to generally more fractionated source rocks, that were heterogeneous, but well mixed. The presence of lithoclasts indicates a possible metamorphic component was also present in the source area. This is consistent with a source area containing granitoid batholiths, and granite plutonism which is associated with early subduction tectonics and volcanic arc formation during the deposition of the Government and Jeppestown Subgroups (Wronkiewicz and Condie, 1987 and Poujol, et al., 2003, Kositcin and Krapez, 2004). Another important basin wide unconformity is present at the base of the Johannesburg Subgroup, and marks another major provenance change. These rocks are chemically more mature than the Government and Jeppestown Subgroups and represent a shift to an immature fluvial depositional setting related to basin closure (Beukes, 1995). A shift to moderate Th:Sc and La:Sc suggests a less fractionated mix of source rocks. The disappearance of the lithoclasts indicates that the metamorphic source rocks no longer supplied material to the basin. A small increase in the chromite to zircon ratio also suggests that some unfractionated source rocks were present. The narrow range in Th:Sc, La:Sc, Nb:Y ratios suggests that a homogeneous source area is present, but this is contradicted by the highly variable zircon ages measured by Kositcin and Krapez (2004), so the narrow spread might indicate that the rocks are very well mixed. Zircon populations measured by Kositcin and Krapez (2004) suggest that source terrain of the Johannesburg Subgroup probably consisted of a mixture of the granitoid batholiths from which the Government and Jeppestown Subgroups are a derived as well as some intermediate igneous material with ages of 3000-2870 ma. This would reflect incorporation of syntectonic granitoid plutons into the source areas, Kositcin and Krapez, (2004). The Turffontein Subgroup rocks are very coarse and chemically mature, but they display poor to moderate sorting and rounding. The rocks were deposited in a fluvial environment but marine quartzites are not uncommon. It is believed that these rocks were transported in a high energy environment, but the duration of transportation was short. This allows for effective winnowing but insufficient time for physically mature rocks with well-rounded grains to develop, explaining the mature chemical composition but immature physical composition. The source rocks of the Turffontein Subgroup were probably the same as the Johannesburg Subgroup with the higher energy mode of transportation responsible for the observed increase in Zr:Ti ratio. It would also explain the scarcity of feldspars and chlorite in the Turffontein Subgroup. Th:Sc and Nb:Y ratios suggest highly fractionated source rocks, but care must be taken because the mature nature and coarse grainsize of these rocks make trace element analyses unreliable. The zircon population indicates the presence of 3090-3060ma (Kositcin and Krapez, 2004) granite batholiths, as well as 3000-2870 Ma (Kositcin and Krapez, 2004) syntectonic granite plutons, as well as ancient granitoid gneiss (Kositcin and Krapez, 2004) in the source area. This study has provided new support for a foreland basin origin of the Witwatersrand Supergroup, proposed by Beukes (1995), Beukes and Nelson (1995) and Nhleko (2003), resulting from orogenic collision of the Witwatersrand and Kimberley blocks along the western margin of the Witwatersrand block. The Amalia, Kraaipan and Madibe greenstone belts and Colesberg Magnetic Anomaly are probably the only remaining remnants of this orogeny today.
