Text in Afrikaans / In die verhandeling word daar gepoog om vas te stel of selfdeterminasie wel as 'n beginsel in maatskaplike werk, deur die maatskaplike werkers van die Hoeveldstreek in Mpumalanga, erken en toegepas word. Die ondersoek het ten doel om te bepaal vanuit watter teoretiese raamwerk die maatskaplike werkers hulle dienslewering rig en hoe die beginsel selfdeterminasie binne die werkers se teoretiese raamwerk geakkommodeer en aangespreek word. Die ekosistemiese benadering is deur navorser gebruik as teoretiese raamwerk. Die inhoud word weergegee in terme van 'n literatuurstudie, waarin die beginsel selfdeterminasie, as sodanig aangespreek word, dan die epistemologie van die maatskaplike werker, asook die uitwerking van selfdeterminasie op dienslewering aan kliente. Inligting is verkry deur middel van 'n vraelys wat deur maatskaplike werkers in die praktyk voltooi is. Die gevolgtrekkings en aanbevelings gee 'n aanduiding van hoe selfdeterminasie erken en toegepas word en hoe die maatskaplike werkers die beginsel akkommodeer met betrekking tot hulle epistemologie. / In this dissertation the attempt is made to establish whether selfdetermination as a principle in social work is acknowledged and applied by the social workers of the Highveld region in Mpumalanga. The aims of the research were to establish the theoretical frame of reference which directs the social workers services and how the principle of self-determination within the social workers frame of reference is accommodated and applied in practice. The researcher has used as her theoretical frame of reference the ecosystemic approach. The contents of the dissertation is presented in terms of a literature study, in which the principle and the effect of self-determination on the services of the social worker to her clients, as well as her theoretical frame of reference is addressed. Information was obtained by means of a questionnaire which was completed by social workers in the field. The conclusions and recommendations give an indication of how selfdetermination is acknowledged and applied and if the social workers accommodated the principle of self-determination with their epitemology. / Social Work / M.A. (Social Work)

Thesis (M. Ed. (Curriculum Studies)) -- University of Limpopo, 2021 / Learners’ academic achievement occupies a very important place in education as well as in the learning process. This study was therefore conducted to investigate factors causing the underperformance of grade 12 learners in secondary schools in Ermelo, Msukaligwa 1 circuit in Gert Sibande district Mpumalanga Province. The qualitative approach was used. Qualitative data generation techniques (semi- structured face to face, observations and document analysis) were used to solicit the understanding of parents, grade 12 learners, grade 12 teachers and heads of department with regard to the phenomenon being studied. The sample size of 22 participants (6 parents, 6 learners, 4 heads of departments and 6 grade 12 teachers) were selected through purposive sampling technique. Data generated through interviews was analysed by using thematic analysis approach. Findings revealed that there are possible factors that cause poor academic performance in Grade 12. Factors include home related factors, school related factors, teacher related factors, parent related factors and learner related factors. Identified home related factors were the size of the family, unpredictable environment at home as well as low financial income. School related factors included overcrowded classrooms, shortage of textbooks, planned and unplanned programmes. Teacher related factors included non-attendance of classes, inadequate content coverage, non-implementation of subject improvement strategies and excessive code switching. Learner related factors included late coming and attitude towards learning. Parent related factors include poor parental support and inadequate level of education. Based on the findings, the study recommends that appointed heads of department should be responsible for the management of subjects they are qualified to manage. Again, the department of education revisits the implementation of the policy of progression so that only learners deserving to be promoted to the next grade are promoted.

Thesis (M.Ed.(Curriculum Studies)) -- University of Limpopo, 2022 / The liability for the decline in performance in Grade 12 Accounting learners in Ehlanzeni District has been levelled against lack of resources in schools, teachers’ inability to execute their duties and poorly trained teachers. Arising from this indictment, this study was conducted to investigate the effectiveness of assessment methods used for Grade 12 Accounting learners in Sikhulile and Mgwenya Circuits in Ehlanzeni District of Mpumalanga Province. A qualitative survey case study was used as a research design. Data was collected using one-to-one interviews among five Accounting teachers, five Heads of Department and five Principals. Qualitative data was presented using thematic and narrative analysis. The key findings were: (1) inadequacy of Accounting workshops and non-attendance by teachers, (2) lack of pedagogical content knowledge (PCK) by Accounting teachers, (3) Accounting content gaps among learners and difficulties in the content area such as Balance Sheet and Cash Flow Statement, (4) shortage of Accounting Learning Teaching Support (LTSM), (5) inadequacies in pedagogical technological devices for teaching, learning and assessment in Accounting, (6) poor teaching and assessment methods used in Accounting and (7) inadequate support from the Department of Education. The study recommends increased frequency of workshops and making attendance compulsory, strategies to improve the pedagogical content knowledge of Accounting teachers, providing in-service training in Accounting to EMS teachers, improved supply of educational resources, improving the schools’ digital infrastructure such as internet connectivity and accessibility to digital devices, improving teachers’ pedagogical skills and digital skills and palpable Departmental support to teachers

This study examined the level of awareness, knowledge and practices of primary and secondary schools students with regard to waste management. Only a limited number of studies were found to evaluate school student’s awareness, knowledge and practice of waste management in South Africa. Literature was reviewed dealing with waste management awareness, knowledge and practices of school students and discussed at the hand of the principles, objectives and targets of the South African Government towards waste and waste management. Using a structured, self-administered questionnaire, a total of 815 students were surveyed from four primary schools and three secondary schools from the Embalenhle and Secunda area Govan Mbeki Municipality, Mpumalanga South Africa. The data were analysed by the use of descriptive statistics including frequency count, percentage, mean and standard deviation. Other analyses employed included two-way frequency tables with Pearson Chisquare test, Phi coefficient, in order to determine the significant relationship between students’ socio-demographic variables. The study showed that the students were obviously aware of concerns with waste and waste management practices in their schools and local environment. It was also apparent the school students had an acute awareness that poor waste management would have a negative impact on the country as well as on them as the individual. This prominent awareness was however not evident in the students’ waste management practices. Good waste management practices activities were minimal at both the school and home environment. Since school students are seen as one of the key agent of change to work towards a more sustainable future, they should be engaged as young as possible and given a quality array of continuous learning to improve their knowledge on environmental problems such as poor waste management. Improved knowledge would contribute to improved environmental awareness and a pro-environmental attitude. The critical recommendations of the study are that the South African Government will have to intensify the research to better understand the needs of children to environmental matters such as waste management. / M.

The purpose of the study was to evaluate the impact of the Termination of Pregnancy (TOP) programme in South Africa, using Mpumalanga as focal area, with the view of developing guidelines to assist service providers in the implementation of the Choice on Termination of Pregnancy (CTOP), Act 92 of 1996. The study was conducted in two phases. In phase 1, a qualitative, quantitative, contextual, explorative, descriptive and case study research design was utilised. The purpose was to explore and describe TOP service providers and facility managers’ knowledge regarding the CTOP Act, as well as their experiences and feelings regarding TOP provision, and the feelings and experiences of health care consumers utilising TOP services. Records of attendance regarding the utilisation of the services were also reviewed. Data was collected using unstructured and semi-structured interviews. Phase 2 of the study focused on the development of guidelines to assist in the translation of the CTOP Act to action at service level. The findings revealed that although the TOP programme was operating within the reproductive health for women initiative, TOP service providers and facility managers were not knowledgeable on other legislation that supports the CTOP Act to integrate its implementation. All the participants experienced emotional, physical and psychological discomfort in providing TOP services. Lack of support of the programme also posed a major challenge. These findings formed the basis for the development of the guidelines. / Health Studies / (D.Litt. et Phil. (Health Studies))

Thesis (PhD)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: Earth’s oldest preserved granitoid crust dates back to the Paleoarchean and consists predominantly of sodic tonalite-trondhjemite-granodiorite (TTG) granitoids that arose through the partial melting of hydrated metabasalts. In contrast, granites (sensu stricto) typically postdate the TTG and appear late in the plutonic record of the old cratons. However, the existence of Hadean zircons with mineral inclusion suites that are consistent with crystallization from peraluminous granitic magmas indicates that granitic rocks formed part of the earliest felsic crust; although we have direct evidence, this earliest felsic crust is not preserved. In this PhD I present an unusual variety of markedly CaO-poor, K2O-rich, rutile-bearing, peraluminous granite and rhyolite that are located in the basal conglomerate of the Moodies Group (South Africa). These rocks challenge the common view of the Archean craton evolution as they were produced concurrently with TTG magmas during three magmatic cycles in the Barberton Greenstone Belt (BGB) and were later emplaced, as clasts, in a younger conglomerate. The study of mineral inclusions located in the zircons present within the granites and rhyolites, shows that alkali feldspar inclusions are abundant relative to plagioclase inclusions and demonstrates that the main characteristics of these granites, i.e. they are K-rich and Ca-poor, are a magmatic signature. The oxygen isotope signature of these zircon grains reveals that the zircons have preserved the δ18O value of the magma from which the granites originated and that the source of the granites had a magmatic oxygen isotope value close to the one of the regional coeval TTG. Further study of the zircons shows that their Lu-Hf isotopic system reflects the crustal signature of the magma into which they grew. Sm-Nd study of the granites and rhyolites whole rock indicates that the minimum age of the source’s protolith of the granites and rhyolites is close to 3.9 billion years, which is in agreement with the zircons’ Lu-Hf signature. Additionally I show in this thesis that the peraluminous character of the granites and rhyolites, along with their high Sr and low Ca content associated to their Eu/ Eu* ~ 1 is a consequence of phengite melting in a metagreywacke source at pressures in excess of plagioclase stability. My work therefore illustrates that K-rich, Ca-poor peraluminous granites were generated in the Paleo and Meso Archean, alongside with the sodic TTG, through partial melting of sediments at high pressures. Not only has this process demonstrated the ability of the early Earth to recycle relatively young material since 3.9 billions years ago, but it has also contributed to each episode of continental crustal growth through the Paleoarchean to Mesoarchean in the BGB, despite leaving no plutonic record at the typical mid-crustal level of exposure that the TTG plutons around the belt represent. / AFRIKAANSE OPSOMMING: Die aarde se oudste bewaarde granitoïed kors dateer terug na die Paleo Argeïkum en bestaan hoofsaaklik uit natrium-ryke tonaliet-trondhjemiet-granodioriet (TTG) granitoïede wat ontstaan het deur die gedeeltelike smelting van gehidreerde metabasalte. In teenstelling hiermee is graniete (sensu stricto) tipies jonger as die TTG’s en verskyn laat in die plutoniese rekord van die ou kratons. Die bestaan van Hadeaanse zirkone met mineraal insluitsels wat ooreenstem met die kristallisasie van peralumineuse granietiese magma dui egter daarop dat granietiese gesteentes deel gevorm het van die vroegste felsiese kors. Alhoewel daar direkte getuienis is hiervoor het hierdie vroegste felsiese kors nie behoue gebly nie. In hierdie dissertasie toon ek ‘n ongewone verskeidenheid van merkbaar CaO-arm, K2O-ryk, rutiel-draende, peralumineuse graniet en rioliet wat in die basale konglomeraat van die Moodies Groep (Suid-Afrika) voorkom. Hierdie gesteentes daag die algemene siening van Argeïkum kraton evolusie uit omdat hulle gelyktydig met TTG magma geproduseer is tydens drie TTG magmatiese siklusse in die Baberton-groensteenstrook en later ingeplaas is as klaste in ‘n jonger konglomeraat. Die studie op minerale insluitsels in zirkone binne die graniete en rioliete toon dat alkaliveldspaat insluitsels volop is relatief tot plagioklaas insluitsels. Dit toon ook dat die hoof eienskap van hierdie graniete, hulle K-ryke en Ca-arme samestelling, ‘n onderskeidende magmatiese kenmerk is. Die suurstof-isotoop samestelling van hierdie zirkoon minerale onthul dat die zirkone die δ18O waarde van die magma waaruit die graniet gevorm is behou het en dat die bronnemateriaal van die graniete ‘n magmatiese suurstofisotoop waarde gehad het nader aan dié van die plaaslike sinchroniese TTG waardes. Verdere studie van die zirkone dui daarop dat hul Lu-HF isotoopstelsel die aardkorseienskappe weerspieël van die oorspronklike magma waarin hulle gegroei het. Sm-Nd studie van die graniete en rioliete heelgesteente dui daarop dat die minimum ouderdom van die protoliet van graniete en rioliete ongeveer 3,9 biljoen jaar is, wat ooreenstem met die zirkone se Lu-HF eienskappe. Daarbenewens het hierdie dissertasie bewys dat die peralumineuse karakter van die graniete en rioliete, tesame met hulle hoë Sr- en lae Ca-inhoud geassosieer tot hul Eu/Eu * ~ 1, ‘n gevolg is van “phengite” smelting in’ n metagrouwak bron by drukking hoër as plagioklaas stabiliteit. Hierdie studie illustreer dus dat K-ryke, Ca-arme peralumineuse graniete gegenereer is in die Paleo en Meso Argeïkum, saam met die natrium-ryke TTG’s, deur middel van parsiële smelting van sedimente teen ‘n hoë druk. Hierdie proses het nie slegs getoon dat die vroeë aarde sedert 3,9 biljoen jaar gelede die vermoë gehad het om relatief jong materiaal te herwin nie; dit het ook bygedra tot elke episode van kontinentale korsgroei deur die Paleo en Meso Argeïkum in die Barberton groensteenstrook, ten spyte daarvan dat geen plutoniese rekord gelaat is teen die tipiese mid-kors vlak van blootstelling wat die TTG plutone in die strook verteenwoordig nie. / RESUMÉ: La croûte de granitoïdes de la Terre Primitive la plus ancienne qui ait été préservée remonte au Paleoarchéen et se compose principalement de granitoïdes sodiques tonalite-trondhjémite-granodiorite (TTG) qui se sont formés par la fusion partielle de métabasaltes hydratés. En revanche, les granites (stricto sensu) sont en général postérieurs aux TTG et apparaissent tardivement dans les cratons anciens. Cependant, l’existence de zircons Hadéens préservant des suites d’inclusions minérales qui sont compatibles avec la cristallisation à partir d’un magma granitique peralumineu, indique que les roches granitiques faisaient aussi partie de la croûte felsique de la Terre Primitibe; même si nous n’avons pas de preuves directes et que cette dernière n’ait pas été conservée. Dans cette thèse, je présente une variété inhabituelle de granites et rhyolites peralumineux qui sont marquée par une forte teneur en K2O et une faible teneur en CaO et qui possèdent du rutile. Ces roches sont situées dans le conglomérat basal du Groupe du Moodies (Afrique du Sud). Elles défient la vision commune que l’on a de l’évolution des cratons Archéens puisqu’elles ont été produites en même temps que des magmas TTG, pendant trois cycles magmatiques qui ont affecté la ceinture de roches vertes de Barberton (CRVB). Ces roches ont été par la suite mises en place, comme galets, dans un conglomérat plus jeune. L’étude des inclusions minérales localisées dans des zircons présents dans les granites et les rhyolites qui font le sujet de cette étude, montre que les inclusions de feldspaths alcalins sont plus abondantes que les inclusions de plagioclases et démontre que les principales caractéristiques de ces granites, c’est à dire qu’ils sont riches en K et pauvres en Ca, sont une signature magmatique. La signature isotopique de l’oxygène de ces zircons révèle que ceux-ci ont conservé la valeurdu δ18O du magma à partir duquel les granites se sont formés. De plus ceci montre que la valeur du δ18O de la source des granites était proche de celle de TTG contemporains. La poursuite de l’étude des zircons montre que leur système isotopique Lu-Hf reflète la signature crustale du magma dans lequel ils ont cru. L’étude Sm-Nd des granites et rhyolites indique que l’âge minimum du protolithe de leur source est de près de 3,9 milliards d’années, ce qui est en accord avec la signature Lu-Hf des zircons. De plus, je montre dans cette thèse que le caractère peralumineux des granites et des rhyolites, avec leurs forte teneur an Sr et basse teneur en Ca associé à leur Eu / Eu * ~ 1, est une conséquence de la fusion partielle de phengite dans une source métagrauwacke à des pressions supérieures a celle de la stabilité du plagioclase. Mon travail montre donc que des granites peralumineux riche en K et pauvre en Ca ont été générés durant le Paléo et Méso-Archéen, aux côtés des TTG sodiques, par la fusion partielle de sédiments, à haute pression. Non seulement ce processus a démontré la capacité de la Terre Primitive à recycler du matériel relativement jeune et ce, dès 3,9 milliards d’années; mais il a également contribué à chaque épisode de croissance crustale à travers le Paleo- et Méso-Archéen dans la CRVB, malgré l’absence de pluton mis en place profondeur à des profondeurs identiques à celles des TTG.

Magister Scientiae - MSc / The objectives of this study were: To review and understand flow and transport processes in unsaturated zones. In this study, particular emphasis is placed on understanding mechanisms that cause non-uniform (preferential) flow for two casestudies, namely the Cape Flats sandy environment and the Mpumalanga Highveld fractured rock environment. To evaluate the adequacy of models, in particular MACRO 5.0, in simulating flow and transport in the vadose zone, by making use of two case study sites (Cape Flats and Mpumalanga Highveld). Of particular importance is the evaluation of transfer coefficients to represent fluid and solute exchange between macropores and matrix. To run a sensitivity analysis with MACRO 5.0 in order determine which input model parameters are the most relevant in describing the effects of preferential flow in water and solute transport.

ABSTRACT This thesis investigates political violence between the United Democratic Front and Inkatha in Mpumalanga township, Natal. In the early 1980s and early 1990s Mpumalanga was one of Natal’s townships most gravely affected by political violence. I ask and answer four questions: 1. Why and how did the conflict between political organisations in Natal become violent? 2. What forms did the violence take? 3. Why, as a result of the violence did ordinary people with little prior history of political activity come to identify with either the UDF or Inkatha? 4. How were these political identities produced? In order to answer these questions the thesis explores three primary arguments. The first argument is that 1987 represents a severe rupture in the politics of Natal. This rupture is captured in the violent form of political conflict that gripped the province. To understand this rupture the thesis looks back at a complex set of processes that interlocked over space and time. A second major argument of the thesis is that an aspect of the distinctiveness of the violence was its profoundly spatialised form in combination with gendered and generational forms. There were two major shifts in the spatialised form of the violence. The first shift occurred when instead of only attacking individuals, the household and its members also became targets. And then the second shift was when the purpose of the violence was about the pursuit of territory. Boundaries between territories identified who was ‘in’ and who was ‘out’ and all aspects of everyday life became politicised. The third major argument of the thesis is that there was a strong relationship between space/place and political identity. The re-territorialisation of space - iv - during the violence was central to the production of these new identities. Political violence created new spatialities, with space itself acquiring political meaning and identity. The political meanings of these spaces were intense markers of their identity and overrode all other meanings and identities. As the spatial form of the violence shifted it forced people to question their political identities. The lived experience of the politicisation of everyday life by the violence shaped the production of political identities.
