Die aanvanklike rotsbeweging van seismiese gebeurtenisse in die Klerksdorpgoudveld

Potgieter, Gert Johannes 12 February 2014 (has links)
M.Sc. (Geology) / There was a possibility that the rockbursts experienced in the faulty Klerksdorp Goldfield area could be related to the numerous faults, fractures and dykes occurring in the area. Until the end of 1979 it was impossible to establish with any degree of certainty which discontinuity was associated with most of the seismic events, as the location network was too inaccurate at that stage to determine such associations. The accuracy of the network was subsequently improved to 30 m in all directions in a specific area of the macro-network. Twenty seven percent of the seismic events which located in this area, occurred less than 30 m from the faults, 21 percent were less than 30 m from the dykes, while 42 percent occurred less than 30 m from dykes and faults. The remainder ( 10 percent) were located more than 30 m from any of the abovementioned discontinuities.

The perceptions of Black adolescents of aggression.

Musekene, Naledzani Arenos 14 October 2008 (has links)
M.Ed. / The goal of this research study was to provide Psycho-Educational guidelines to assist adolescent learners to manage aggression in a constructive manner. The participants in this research study were adolescent learners at age of fifteen to seventeen years in Secondary Schools in the of Klerksdorp area. Adolescence is a phase in human development that is synonymous with change, namely, physical, emotional and cognitive changes. It is a crucial phase of development. Aggression is simply defined as a behavior that is intended to hurt someone either physically or psychologically (Weiten, 1992:397). However there are many theorists who define aggression differently but state anti-social behavior as a characteristic. The researcher wanted to formulate guidelines after exploring and describing the perceptions of black adolescence on aggression. It was because this aggressive behavior was impacting on their future successes. The research objectives were as follows: „« To explore and describe the perception of black adolescents of aggression in an informal settlement „« To formulate guidelines to assist black adolescents to manage aggression in a constructive manner. The qualitative research approach helps the researcher to understand and interpret adolescents¡¦ perception on aggression. The information gathered in this study would help determine topics for further research on adolescents¡¦ perceptions on aggression. Focus group interviews were conducted. This study was explorative and descriptive as it aimed to obtain adolescents¡¦ perceptions on aggression. The researcher attempted to find out how adolescents perceived aggression by conducting focus group interviews. Interviews were conducted with four groups. The major themes were: „« Black adolescents in an informal settlement school express different views on what aggression is „« Black adolescents in an informal settlement school experience forms and acts of aggression at school „« Black adolescents experience a sense of being so victimized in schools that it made their school lives miserable. „« View points that necessary structures should be put in place with the objective of providing guidelines to assist black adolescents in an informal settlement school to manage aggression in a constructive manner From the interviews conducted, recommendations were made to reduce the problems caused by aggression. / Prof. C.P.H.

Challenges experienced by learners with visual impairment in two mainstream primary schools in Klerksdorp, Dr. Kenneth Kaunda District

Morelle, Mokwena 09 1900 (has links)
The purpose of this study is to explore the challenges experienced by learners with visual impairment in two mainstream schools in Klerksdorp, Dr Kenneth Kaunda District. The aim is to describe the challenges experienced by visually impaired learners and how they are truly included in the mainstream school curriculum, to analyse the nature of support as well as the adaptation and accommodation made for learners with visual impairment in the mainstream schools. I purposefully selected the participants and used semi-structured interviews; observation method was also used to enhance the information collected during the interviews. A qualitative research approach was followed, underpinned by interpretive method as a paradigm. The participants included in two schools in Dr Kenneth Kaunda District were four teachers teaching learners with visual impairment (two from each school), two parents of learners with visual impairment, four learners with visual impairment (two from each school), one specialist (itinerant) teacher designated to assist and support learners with visual impairment in both schools and two principal (one from each school). A total of thirteen participants were involved in this study. The data were audio-recorded for accurate transcription and analysis. From the research it was found that even though the learners with visual impairment are now physically integrated in the mainstream classes, they are not yet truly included. The teachers are not adequately supported and trained and most of the parents of learners with visual impairment are not involved in their children’s schooling. The teaching methods and materials are not adequately adapted for them and the physical environment within the classes and school grounds are not yet truly accessible for them. The school needs resources and change in teachers’ attitude; teachers do not understand the rationale behind inclusive education. Finally, the vision and mission statements of the school were drafted but did not provide a clear and practical guideline towards the inclusion of learners with visual impairment. I hope that the findings of this study will be of valuable use to both schools in Dr Kenneth Kaunda District and to the Ministry of Basic Education with regard to progress in the inclusion of LVI in the mainstream. / Inclusive Education / M.

Causes of non-adherence to antiretroviral therapy in Wellness Clinic, Tshepong Hospital, Klerksdorp

Das, C. R. 12 1900 (has links)
ENGLISH ABSTRACT: HIV/AIDS is the leading cause of death in Sub-Saharan Africa. According to 2001 estimates, there are 28.5 million people living with HIV in Africa, comprising more than 70% of the world’s HIV-infected population. HIV/AIDS remains one of the most important social and public health threats in Sub-Saharan Africa. UNAIDS 2006 estimates that 5.5 million people are living with HIV, and almost 1,000 AIDS deaths occur every day in South Africa. South Africa is currently one of the most severely affected countries in the world. Antiretroviral therapy (ART) is currently the only treatment available for HIV. It does not cure HIV infection, but reduces HIV related mortality and morbidity. / AFRIKAANS ABSTRACT: No abstract available

The petrogenesis of the volcanic rocks of the Witwatersrand triad in the Klerksdorp area, Transvaal

Bowen, Michael Peter January 1985 (has links)
Several hundred chemical analyses of early Proterozoic lavas of the Witwatersrand triad (incorporating the Dominion Group, Witwatersrand Supergroup and Ventersdorp Supergroup) in the Klerksdorp area, have revealed the presence of various distinct magma types. These essentially correspond to formally defined lithostratigraphic units, but several inconsistencies have necessitated the use of informal nomenclature. The lavas have been regionally metamorphosed to low-grade, greenschist facies assemblages. Original igneous textures are preserved, despite a metamorphic overprint. Metamorphism has resulted in a certain degree of random chemical remobilization. Ba, Sr, Rb, K₂0, Na₂0 and CaO have been highly mobile, and their usefulness in petrogenetic modelling is extremely limited. In contrast, Zr, Nb, Y, LREE's, Cr, Ni, Ti0₂ P₂0₅ and Al₂0₃ have remained immobile. Ti/Zr and Ti/P ratios together constitute efficient discriminating variables for characterizing the different magma types. Lava compositions range from primitive Mg-rich tholeiites to rhyolites, the bulk being tholeiitic andesites. Al₂0₃ contents do not exceed 15%, a feature which reflects the tholeiitic, as opposed to calcalkaline, character of these lavas. Two magma-types are present within the Dominion Group, which is a typical example of bimodal volcanism. The Dominion basic lavas are overlain by the Dominion acid porphyries, with a limited amount of interfingering. The basic lava suite is highly fractionated, with compositions ranging from Mg-, Cr- and Ni-rich tholeiites (close to primary mantle melts) to evolved tholeiitic andesites. The most primitive liquids evolved by 45% fractional crystallization of hornblende, followed by a further 70% crystallization of an orthopyroxene-plagioclase assemblage containing up to 3% sulphides. The Dominion porphyries are rhyolitic, display very limited compositional variation, and probably represent a crustal melt related to the same magmatic event which produced the basic lavas. The only lavas from the Witwatersrand Supergroup present in the Klerksdorp area are those of the Crown Formation (Jeppestown amygdaloid). These are tholeiitic dacites which display extremely limited compositional variation, and are unrelated to any of the other magmas of the Witwatersrand triad. The Ventersdorp Supergroup comprises 4 magma-types: The Kliprivierberg Group lavas at the base are subdivisible into 3 sub-types on the basis of Zr contents. (Zr>11Oppm) are the most evolved. They are tholeiitic andesites which display fairly limited compositional variation. It is likely that more evolved compositions are present in other areas where the porphyritic lavas which characterize this unit are better developed. The overlying Orkney lavas are characterized by 110ppm>Zr>90ppm. They are tholeiitic andesites of similar composition to the Alberton lavas, but have lower incompatible element levels, higher siderophile element levels, and are of extremely uniform composition. The uppermost Loraine/Edenville lavas range from magnesian tholeiites to tholeiitic andesites. They are distinguished by Zr< 90ppm, and contain the most primitive magmas af the Witwatersrand triad, with up to 17,5% MgO, 2600ppm Cr, 600ppm Ni and M-values up to 77. The most primitive liquids evolved by 38% fractional crystallization of orthopyroxene ∓ chromite, followed by 35% fractional crystallization of an extract containing clinopyroxene and plagioclase. The absence of olivine precipitation is a result of the inherently high Si0₂ content of the magma. The Loraine/Edenville, Orkney and Alberton lavas do not lie on a common liquid line of descent, but are probably consanguinous. The Platberg Group overlies the Kliprivierberg Group, and has a coarse-clastic sedimentary unit, the Kameeldoorns Formation, at the base. Three petrographically distinct porphyritic lava sequences overlie the Kameeldoorns Formation, namely the informal "Goedgenoeg formation", the Makwassie quartz-feldspar porphyries and the Rietgat Formation. Despite petrographic differences, the Goedgenoeg and Rietgat lavas are chemically indistinguishable and thus form a single magma-type. The Makwassie porphyries are dacitic in composition with a high proportion of feldspar and quartz phenocrysts. Rational variation trends are attributed to a nett loss of Si0₂ during secondary alteration. The porphyries are probably of crustal origin. The Goedgenoeg/Rietgat lavas display unusual chemistry and a broad, irrational compositional spectrum. They contain very high incompatible element levels, high nonnative quartz, as well as high MgO, M-values, Cr and Ni relative to the other tholeiitic andesites of the Witwatersrand triad. It is tentatively suggested that they are hybrid magmas containing both crust and mantle components, the former possibly represented by the Makwassie porphyries. Field evidence suggests that Platberg volcanism commenced directly after Klipriviersberg volcanism ceased, and was accompanied by a period of enhanced tectonic activity. The Platberg lavas thus probably reflect a crustal melting cycle associated with the Klipriviersberg magmatic event. The Allanridge lavas are the youngest rocks of the Witwatersrand triad. They are separated from the Platberg Group by a unit of flat-lying sediments, the Bothaville Formation, which was deposited after an extended period of peneplanation. The Allanridge lavas form a separate magma-type. They are tholeiitic andesites of similar composition to the Alberton lavas, but have higher incompatible element levels and are not consanguinous. The compositional similarities amongst the basic magma-types of the Witwatersrand triad suggests that all were generated in an hydrous mantle. Interelement ratio differences between the various magma-types nevertheless support the concept that the mantle was chemically heterogeneous during the early Proterozoic.

A municipal structure for the KOSH area

Dodovu, Thamsanqa Simon 12 1900 (has links)
Thesis (MPA)--Stellenbosch University, 2000. / ENGLISH ABSTRACT: South African local government is undergoing a critical process of transformation and restructuring. New structures, institutions and systems which are being established change local government to accomplish the developmental objectives of the society, improve service delivery and ensure optimum governance. The study is aimed at investigating and examining the type of municipal structure that has the capacity to achieve the objectives of local government. In this regard, the status quo of municipalities in the KOSH (Klerksdorp, Orkney, Stilfontein and Hartebeesfontein) area, a metropolitan municipality without sub-councils and an amalgamated Category B Municipality operating in the area of jurisdiction of Category C Municipality is explored and critically examined. The hypothetical statement namely that the KOSH area requires a restructured, rekindled and revitalised municipal structure and the amalgamation of unviable municipalities into a larger jurisdiction to sustain development, are tested. A review of new structures and systems of local government in South Africa is made. In this regard the legal framework and context of the municipal demarcation process, structures and systems is of paramount importance. A critical analysis of all municipalities in the KOSH area including the Southern District Council in relation to their political and administrative components is made. The background and profile of each town and city in the KOSH area is also given. This encapsulates the historical background of the area, its economy and socio-demographic profile. In the final analysis the study highlights the positive and negative effects of amalgamated municipalities whether Category A or B Municipalities. The study concludes that the KOSH area lends itself to the establishment of an amalgamated Category B Municipality operating within the jurisdiction of a Category C Municipality. The study also concludes that it is possible and viable to de-establish the present separate local authorities and create a viable amalgamated Category B Municipal structure that will improve service delivery and provide optimum governance for the KOSH area. Specific recommendations in respect of the development of the KOSH area are made. / AFRIKAANSE OPSOMMING: Suid Afrikaanse plaaslike regering ondergaan 'n kritieke proses van transformasie en herstrukturering. Nuwe strukture, instellings en sisteme wat geskep word verander plaaslike regering ten einde die ontwikkelingsoogmerke van die gemeenskap te bereik, dienslewering te verbeter en om optimum regering daar te stel. Die studie is gemik op die ondersoek en ontleding van die soort munisipale strukture wat in staat is om die bogemelde oogmerke te bereik. In hierdie verband, word die status quo van munisipaliteite in die KOSH (Klersksdorp, Orkney, Stilfontein and Hartebeesfontein) gebied, 'n metropolitaanse munisipaliteit sonder sub-rade, en 'n geamalgemeerde kategorie B munisipaliteit wat in die jurisdiksionele gebied van 'n kategorie C munisipaliteite funksioneel ondersoek en krities ontleed. Die hipotese naamlik dat die KOSH gebied 'n gestruktureerde, munisipale struktuur benodig sowel as die amalgamering van nie-lewensvatbare munisipaliteite in 'n groter jurisdiksie om ontwikkeling te handhaaf, word ondersoek. 'n Oorsig word gegee van die nuwe strukture en sisteme van plaaslike regering in Suid Afrika. In hierdie vervand is die regsraamwerk en die konteks van die munisipale afbakeningsproses, strukture en sisteme van kardinale belang. 'n Kritiese ontleding van al die munisipaliteite in die KOSH gebied, insluitende die Suidelike Distriksraad, uitsluitende hul politieke en administratiewe samestelling, is gemaak. Die agtergrond en die profiel van elke dorp en stad in die KOSH gebied work ook weergegee. Dit sluit in die geskiedkundige agtergrond van die gebied, asook die gebied se ekonomie en sosiodemografiese profiel. In die finale ontleding beklemtoon die studie die voor-en nadele van geamalgameerde munisipaliteite, ongeag of hulle kategorie A of B munisipaliteite is. Die studie toon aan dat die KOSH gebied homself leen tot die skepping van 'n ge-amalgameerde kategorie B munisipaliteit wat binne die jurisdiksie van 'n kategorie C munisipaliteit opereer. Die studie het ook aangetoon dat dit moontlik en haalbaar is om die bestaande aparte plaaslike owerhede te hervestig en 'n haalbaar kategorie B munisipale struktuur daar te stel wat dienslewering sal bevorder en optimum regering vir die KOSH gebied daar sal stel. Spesifieke aanbevelings word gemaak met betrekking tot die ontwikkeling van die KOSH gebied.

A comparison of policies and practices in assessment in a Further Education Institution

Basson, Rene 03 1900 (has links)
Thesis (MPhil (Curriculum Studies)--University of Stellenbosch, 2007. / A new Outcomes-based Education (OBE) system, as well as a new Further Education and Training (FET) framework, has been proposed by the government to address past inequalities and provide a skilled labour force. The introduction of OBE has necessitated a paradigm shift in both educational and assessment practices. The FET policies, led by the introduction of the Green Paper for FET in 1998, aimed to inform the FET institutions on the implementation of outcomes-based assessment. However, the implementation of these policies has posed many obstacles and challenges. Lecturers are unsure about the implementation strategies, and their attempts to cope with these uncertainties are seldom effective. Consequently, lecturers struggle to bring their assessment practices in line with the policies. This was the research problem of the study. The aim of the study was to determine discrepancies between the policies and the practices. The FET policies and related literature were consulted to determine how assessment practices should change. Subsequently, a questionnaire and focus group discussions were used to determine the current assessment practices of lecturers at the Klerksdorp campus of Vuselela College. Thereafter, the requirements of the policies and the current assessment practices of the lecturers were compared to determine the extent to which the lecturers had adopted the new assessment practices. Various discrepancies were found. The first discrepancy existed between the implementation strategies of the new FET curriculum and the actual implementation process at the college. No learnerships had been implemented in the N-courses and the implementation process had been delayed several times. A second discrepancy existed between the requirements for lecturers to be registered as assessors and the registration process. Lecturers completed the training courses but struggled to register as assessors. A bottleneck existed with the registration process because of the number of lecturers that had to be registered. In addition, the training did not provide the lecturers with sufficient knowledge to implement outcomes-based assessment while the training was presented on the wrong National Qualifications Framework (NQF) level. Another discrepancy existed with regard to the implementation of the learnerships and the implementation of outcomes-based assessment. Lecturers were only expected to implement outcomes-based assessment in courses where learnerships had been implemented. This meant that lecturers who lectured on N-courses were still required to use more traditional assessment methods. While some lecturers preferred paper-based assessment methods, other lecturers felt that the restrictions imposed by the DoE were depriving them of the opportunity to use more alternative methods. Problems such as an increase in the workload, administration and paperwork and learner numbers were also experienced. Regarding these discrepancies, it was firstly recommended that the DoE be realistic about implementation dates and be transparent about delays and problems. Lecturers could assist the DoE in the implementation process by writing unit standards. Secondly, it was recommended that the DoE should have an efficient structure in place to deal with the vast number of lecturers that would have to register as assessors. This can be done by employing extra human resources. Better training is necessary to support and empower lecturers to implement outcomes-based assessment. Thirdly, lecturers could be encouraged to implement the new assessment practices by giving them recognition for good work, providing them with assistance and appointing lecturers who act solely as assessors. These discrepancies are more related and the recommendations more useful to this particular college than the assistance that is provided by the DoE by making the college aware of the obstacles and challenges that the new assessment practices pose.

The invisible director : an exploration of the role of power in intergovernmental communication on meaningful municipal integrated development planning

Gibbens, Menini 24 June 2009 (has links)
Over the last two decades the impact of power in communicative planning has gained prominence in discussions about meaningful planning, i.e. planning that achieves the goals as set out in the plan and also has wider socially desirable environmental, social and economic outcomes. This study aims to examine the influence of power on communication in the compilation of municipal Integrated Development Planning in South Africa, specifically as it affects intra- and intergovernmental relations in the IDP preparation process in local municipalities. This dissertation is the result of a historical study into the 2000/2001 and 2001/2002 Integrated Development Plan process in the local governments of Kungwini Local Municipality, and Klerksdorp Local Municipality as study areas. The time lapse between the events that took place in these municipalities and the completion of this study assists in providing a more objective view of the power relations at play. Throughout the study emphasis is placed on certain concepts that influence the outcome of planning processes and the planning processes itself, as summarised in the final chapter. They are: <ul> <li> The quality of inter- and intra-governmental relationships;</li> <li> The awareness and use of power in planning;</li> <li> The concept and nature of “meaningful communication”; and</li> <li> The role and impact of power on such communication.</li> </ul> As an exploratory historical study into the power interface in IDP, it provides an interesting perspective on the dynamics of compiling an IDP and opens up the opportunity for more such studies in other local governments in South Africa with the influence of power on communication in intergovernmental planning processes (specifically IDP in local municipalities) and general studies regarding the effect of power in communicative planning as focus. This study also provides an indication of the pressures planners face in the pursuit of meaningful/useful planning results. / Dissertation (MT&RP)--University of Pretoria, 2009. / Town and Regional Planning / unrestricted
