Thesis (MPH.) -- University of Limpopo, 2014 / Background The use of contraceptives among sexually-active teenagers in South Africa is known to be very poor and is currently estimated to be at a rate of 25% (DoH 2002). Teenagers who have unprotected sex are at a high risk of reproductive Health problems, such as Sexually Transmitted Infections (STIs) and HIV/AIDS, and unsafe abortion, amongst others (DoH 2002). Contraceptive use progressively declined between 2002 and 2004 among girls under 18 years in the Kwa-Zulu Natal Province as a whole (Health Statistical Bulletin, 2004). Aim The aim was to determine knowledge, attitudes and perceptions of pregnant teenagers with regard to usage of contraceptives at the Pietersburg Hospital, Limpopo Province, South Africa. Method of data collection and analysis A cross-sectional descriptive survey was used in this study. A self-administered questionnaire was used to collect data from pregnant clients aged 13-19 years of age. Data analysis was carried out by using the computer software called Statistical Program for Social Sciences (SPSS). The findings revealed that lack of knowledge, attitudes and perceptions of pregnant teenagers was a problem. Findings The findings of this study indicated that culture and attitude of nursing personnel were not the barriers. Barriers were “not having enough time to choose the method and just not being serious about contraception”. Thirty-six ix per cent (36%) of the participants said they had enough time to choose the method, but they did not choose. Sixty per cent (60%) said they were not serious about contraception, 40% said they were serious but did not use contraception. Married participants who did not hear about emergency contraception, the percentage was small, 6%, while the percentage of single women was higher (94%). Conclusion The study revealed that the participants had knowledge of contraceptives, both single and married; however, married women seemed to have negative attitudes towards contraceptives, based on the culture and the believe that, once married, the usage of contraception was not necessary. Based on the findings of the study, it is recommended that there should be effective ways of information giving to the public regarding family planning.

M. Tech. Nature Conservation / Ticks are blood feeding external parasites of mammals, birds, and reptiles throughout the world. Tick infestation is considered to be one of the main constraints to successful game ranching in southern Africa. Several blood parasites are transmitted by ticks and have been incriminated as the cause of death in several wildlife species Ticks thus affect wildlife and domestic animal management worldwide, with approximately 850 species of ticks having been described The aim of the thesis is to collect and describe fully the nature and extent of the tick cohort of a semi-intensive and control free game ranch in the Limpopo Province of South Africa farm and to establish the environmental management effects on tick abundances and species.

M. Tech. Education Tshwane University of Technology 2009. / Determines the effect of language of instruction (LOI) on the performance of learners in Vhembe District, Limpopo Province. The findings revealed that language of instruction has an effect on the performance of learners. There is difference in the performance of learners who use mother tongue as medium of instruction compared to those using second language as medium of instruction. The government practices and peoples perception on the issue of language of instruction in African schools are the main factors hindering the introduction of African languages as medium of instruction in African schools. Recommendations were made that the Department of Education must support the constitutional right to equality of all languages by encouraging local language use in all the activities in local state institutions. The retraining of educators and translation of English books into African languages is to be done as matter of urgency.

Post-apartheid education policy as enshrined in the South African School's Act no 84 of 1996 transformed the education system. The policy ensured the right of access to the school of one's choice and lead to the migration of learners from township schools to former Model C and independent schools. The study aimed to investigate the management of learner migration using a literature review and a qualitative inquiry. Data was gathered through interviews with principals, School Management Team members, parents and learners who had migrated. The findings indicated that learner migration as determined by parents' social and financial capacity is; steered by factors such as a school's sound culture of teaching and learning on account of good principalship, dedicated educators, motivated learners and good discipline. It was recommended that the culture of teaching and learning should be cultivated in all schools through capacity building workshops for educational managers and educators to curb excessive Ieamer migration. / Further Teacher Education / M.

M.Sc. (Aquatic Health) / Aquatic ecosystems in rural South Africa have been impacted over many years by commercial and subsistence anthropogenic activities (DWAF, 2001). These impacts include commercial and subsistence farming, domestic use (e.g. washing of clothes, cars and bathing) and recreational use (e.g. fishing). In the northern parts of the Limpopo Province of South Africa (Vhembe District) the land use is primarily dominated by various agricultural activities and human settlements. Rivers in this region flow through mixed agricultural use, including commercial agriculture (tea and timber plantations) as well as subsistence farming and housing. Perennial rivers in this region include the Mutale, Mutshindudi and Tshinane rivers. These rivers are located in the Water Management Area 2 (WMA 2 Luvuvhu-Letaba) (Kleynhans, et al., 2007a). They are highland river systems, originating in the nearby Soutpansberg Mountain, and these rivers all form part of the larger drainage system of the Luvuvhu River, a tributary of the Limpopo River. The wetlands in the catchment of these rivers are also heavily utilised by the local communities (Working on Wetlands, 2013) used for grazing, sand mining and subsistence cultivation, thus providing a livelihood for the surrounding communities (SANBI, 2012). The aim of the study was to assess aspects of the biological integrity of the Mutale, Mutshindudi and Tshinane rivers. This study formed part of a larger study that included assessments of both abiotic and biotic aspects of these river systems. For this study, the focus was on assessing the fish community structure through the application of Fish Response Assessment Index (FRAI), riparian vegetation through the application of Vegetation Response Assessment Index (VEGRAI) and fish health aspects with special reference to liver and gonadal histopathology. Water quality parameters were found to be within the target water quality range for aquatic ecosystems. The results did however vary between upstream and downstream sampling sites. Similarly, compared to upstream sites, the FRAI showed the Mutale River to improve in fish community structure whereas the Tshinane and Mutshindudi rivers showed a decrease in the FRAI score. The VEGRAI results showed a decrease in EcoCondition in the Mutale and Mutshindudi rivers whereas the Tshinane indicated an increase. This can be attributed to land use change up to the edge of the river systems. Visual observation at the various study sites showed a definite localised impact of human activities on the beds and banks of many parts of the rivers. No histological alterations were identified in any of the gonadal or liver tissue of the Chiloglanis pretoriae (Shortspine suckermouth) (Van der Horst, 1931) and the fish were found to be in a healthy condition according to the selected parameters (gonads and livers) assessed. The fish community structure of the three rivers were found to be in a moderately to largely modified condition according to the ecological state categories calculated. However, the fish health assessment showed no histological alterations in the sampled fish. It is proposed that future studies investigate the influence of the domestic use of the rivers as well as attempt to quantify the impact of agriculture on the system.

The Platreef is a platinum group element (PGE) and base metal enriched mafic/ultramafic layer situated along the base of the northern (Potgietersrus) limb of the Bushveld Complex. It represents an important resource of PGE which is only in its early stages of exploitation. The present study contains a detailed petrographic and geochemical investigation of a borehole core drilled on the farm Townlands. At this locality, the Platreef rests on metasedimentary rocks of the Silverton Formation of the Transvaal Supergroup, and is comprised of three medium grained units of gabbronorite/feldspathic pyroxenite that are separated by hornfels interlayers. I refer to the three platiniferous layers as the Lower, Middle and Upper Platreef. The Middle Platreef is the main mineralized layer, with total PGE contents up to 4 ppm. The Lower and Upper Platreefs are less well mineralized (up to 1.5 ppm). Trace element and S-isotope data show compositional breaks between the different platiniferous layers suggesting that they represent distinct sill-like intrusions. The study also reveals a reversed differentiation trend of more primitive rocks towards the top of the succession. For example, pyroxene shows an increase in Cr2 O3 with height couples with a decrease in TiO2 . Olivine from the Upper Platreef has Fo contents between 80-83 (averaging Fo81) and those from the Middle Platreef have Fo from 78-83 (averaging Fo79 ). The Upper and Lower Platreefs have <FONT FACE="SYMBOL">d</FONT> 34S values averaging 80/00 while the Middle Platreef has <FONT FACE="SYMBOL">d</FONT> 34S values averaging 4 0 /00. All three Platreef layers have elevated <FONT FACE="SYMBOL">d</FONT> 34S values, indicating addition of 34S-enriched crustal sulphur. The model of contamination is supported by elevated K, Ca, Zr and Y contents in the Platreef relative to Critical Zone rocks from elsewhere in the Bushveld Complex, and by high Zr/Y ratios. Well defined correlations between concentrations of the individual PGE, and between the PGE and S suggest that the concentration of the PGE was controlled by segregating sulphide melt. Alteration of the rocks, possibly due to infiltration by fluids derived from the floor rocks, caused localized redistribution of Cu and, to a lesser degree, the PGE. A model is proposed whereby the Platreef magma assimilated calcsilicate and hornfels from the country rocks. The hornfels and calcsilicate of the Silverton Formation that forms the floor rocks to the Platreef on the farm Townlands constitute a possible source of the crystal sulphur. Release of S from the floor rocks caused S-supersaturation in the magma, followed by segregation of an immiscible sulphide melt. The sulphide melt scavenged the PGE from the silicate magma. The sulphides and the xenoliths were entrained by successive, metal-undepleted magma flows, causing high metal tenors in the sulphides and undepleted Ni contents in associated olivine / Dissertation (MSc)--University of Pretoria, 2006. / Geology / unrestricted

The rural women in EMLM hew the wood, carry water, satisfy the men, produce and take care of the children to continue the family tree, and manage all the household chores. Their contribution is central to the effective functioning of families and communities. Yet, in terms of decision-making and local governance structures, they are absent. Indeed, there is truly a large constituency of women out there who are largely unrepresented; and therefore, they have no idea how governance is conducted – even around them. This is unfair, especially in jurisdictions where women are clearly in the majority. It is inconceivable that local governance structures have over a decade recorded only a single elected female member. With this in mind, this study seeks to explore the extent of rural women’s participation in local governance in Elias Motsoaledi Local Municipality. It is a comparison of traditional and democratic local governance structures; and the methods the researcher has used are qualitative and quantitative data on women councillors from 2013, in order to assess the factors that may be accountable for their small numbers, as compared to their male counterparts. The conclusion drawn was that the social structure, its traditions and cultural was identified in the study as the main obstacle to the advancement of women in the political arena. This study has not exhausted all the facets of the challenges; but it has brought a few to the fore, in an attempt to help stimulate debate, and inform policy and practice in the future.

Thesis (M. Dev.) -- University of Limpopo, 2017. / While there are a fair number of studies on land reform in South Africa, there are knowledge gaps on the impact of some specific forms of land redistribution on livelihoods of beneficiaries. The purpose of this study therefore was to assess the impact of the land redistribution in the case of selected farms in the Vhembe District, Limpopo Province, South Africa. A qualitative research method was used and twelve households were interviewed. A number of indicators were used to assess impact. These included household income, job creation, empowerment and sustainability. The selection of indicators was informed by a comprehensive literature review on land redistribution, not only in South Africa but in other parts of the world as well. The findings from the study revealed that the land redistribution beneficiaries are faced with challenges such as poor infrastructure on redistributed farms, limited or lack of access to affordable inputs and lack of financial support immediately after redistribution. These and other challenges makes life for the intended beneficiaries very difficult which in the end makes land redistribution ineffective. A major factor which explains the failure of these farms appeared to be the inadequate planning of post-settlement support. Even though land was effectively transferred to the beneficiaries, the little support they have received in terms of financial, infrastructural and marketing support, for example, has limited their capacity to utilise the land productively and cost effectively. The study recommends that the government and other agencies should consider providing comprehensive support to these communities until they are able to run on their own. Substantial research should be carried out to rethink strategies on land redistribution, particularly on how to handle the issue of title deeds which currently appears problematic in the context of the farms that were studied. Finally, the training programmes for land redistribution beneficiaries should also include training current legislation on land redistribution issues in order to adequately prepare the new land owners for any unexpected challenges as has occurred in the case of the farms that were studied.
