PhD (Health Sciences) / Department of Advanced Nursing Science / Disability is the most painful experience for the mother and relatives when a child is born. This is because every parent expects a normal child once a woman conceives. For a mother to be able to cope with their children they need to be supported emotionally, psychologically and physically by the family members, community, and health care professionals and other support service providers.The overall purpose of the study was to develop a model to support mothers of children with intellectual disabilities in selected institutions of Limpopo Province.An exploratory sequential mixed method was employed which includes both qualitative and quantitative approaches to guide the study.Population was all mothers of children with intellectual disabilitiesand health care professionals from the selected institutions where the research was conducted. Health care professionals were purposively selected whereas mothers were conveniently selected. The study was carried out in two phases i.e Phase1(a & b) and Phase 2. Qualitative results were used to build a subsequent quantitative phase. In Phase 1a,a qualitative approach was employed using descriptive and exploratory designs. Qualitative data was collected through individual interviews.Data analyses were done utilising Tesch’s open coding method.In Phase 1b was quantitative approach wherein a cross-sectional descriptive design was used.Questionnaireswere developed and data were collected from the health care professionals in the selected study areas.Data analyses were done using the Statistical Package for the Social Sciences (SPSS) version 24 and the level of statistical difference being set at p<0,05.In Phase 2, concept analysis, model development and validation of the model were performed. Themes and sub- themes were identified from the analysed data. Current study revealed that some mothers were fully supported and some were not supported at all by both the family, friends, relatives, community members and health care professionals. Hence continuous support was seen to be very crucial to them.The study recommendations include: open communication, social, psychological and emotional support, combined available support services, access to special schools and formulation of support groups. / NRF

MCur / Department of Advanced Nursing Science / Each year, an estimated 3.6 million infants die worldwide in the first four weeks of life due to complications of premature birth. One-third of Low Birth Weight (LBW) babies die within the first 12 hours after delivery. The main reasons premature babies are at greater risk of illness and death is that they lack the ability to control their body temperature meaning that they get cold or hypothermic very quickly. Kangaroo Mother Care reduces mortality and if widely applied it could reduce deaths in premature newborn babies. The purpose of this study is to explore and describe the lived experiences of mothers when providing Kangaroo Mother Care at the hospitals in Vhembe District of Limpopo province. Qualitative approach with explorative descriptive, contextual and phenomenological designs were employed to explore the experiences of mothers when providing Kangaroo Mother Care. The study population consisted of all mothers who were providing Kangaroo Mother Care. A non-probability convenience sampling method was used to determine the sample of the study. The size of the sample was determined by data saturation. In-depth individual interviews were conducted using a central question. The Tesch’s eight steps of open-coding model guided the process to analyse data. Trustworthiness was ensured throughout by employing the principles of credibility, dependability, conformability, and transferability. Ethical considerations were followed to protect the participants. Recommendations were made based on the research findings. The findings of the study revealed that mothers who provide Kangaroo Mother Care experience challenges. They received inconsistent information about the practice of Kangaroo Mother Care from nurses. The relationship between mothers and nurses was good. Recomendations were made based on the findings and relevant structures in order to ensure that mothers challenges are addressed. The study revealed ineffective support provided to mothers by nurses and family members. / NRF

MPH / Department of Public Health / Globally, substance use is a significant public health problem around the world. Many schools encounter the challenge of learners using substances in and outside of the school premises. This problem affects the education system because learners who use substances display behaviours that negatively affect the quality of learning and teaching. The study aimed to determine the educators’ knowledge of the factors contributing to substance use among secondary school learners in Greater Giyani Municipality, Limpopo Province. A descriptive research design was employed, and the participants were selected using purposive sampling. Data was collected utilising a structured questionnaire and analysed using the Statistical Package for Social Sciences (SPSS) version 25 programme. The study findings show substance use as a significant public health problem in schools. Some of the factors identified that contributed to substance use among learners by most educators were low-self-esteem, poor self-control, depression, meagre finances, academic environment, background, peer pressure, accessibility and availability of substances. Based on the findings a number of recommendations were made such as capacitating parents on parenting skills and also on strategies to assist teachers to fight against substance use by students. Instead of the media only displaying lucrative advertisements of alcohol, it must also provide education and awareness about substance use/abuse and its consequences. Further research is necessary to investigate learners’ and parents’ knowledge of the factors contributing to substance use. / NRF

MPH / Department of Public Health / Human Immune Deficiency Virus (HIV) and Acquired Immune Deficiency Syndrome (AIDS) place a significant burden on the caregivers for people living with HIV/AIDS (PLWHA). Caring for PLWHA is usually carried out by community members who are recruited from the same community as the PLWHA. These community members are trained to provide services as volunteer caregivers. The caregivers face various challenges in the process of giving care to PLWHA, often inadequately assisted by relatives, friends, neighbours, private individuals, grassroots traditional and political leaders. This results in caregivers being overwhelmed by their responsibilities, making their coping process even more difficult. The aim of this study was to explore the challenges experienced by community home-based caregivers (CHBCGs) caring for people living with HIV/AIDS at Tsianda Village, in Makhado Municipality, South Africa. This study adopted a qualitative explorative design. The population for this study were all CHBCGs caring for PLWHA. Non probability purposive sampling was used to select the community home-based caregivers working at Tsianda Community Home-based care organisation. In-depth interviews, using a semi-structured interview guide, was conducted by the researcher and a voice recorder were used to record data from participants. Data saturation was reached at the 11th participant. This is when the participants were no longer giving new information. The data collected from the study were analysed thematically. The following themes emerged from data analysis: Challenges for community home-based caregivers, perceived support for community home-based caregivers, coping strategies for community home-based caregivers. Measures to ensure trustworthiness and the code of ethics to protect the rights of the participants was applied and observed. The findings of the study revealed that community home-based caregivers experience various challenges which have a negative impact on their personal life, as well as their physical and psychological wellbeing. Community home-based care also uses different strategies to cope with these challenges. It was concluded that the community home-based caregivers are experiencing serious shortages of personal protective equipment, which makes them work with the fear of being infected with the diseases. It is recommended that the DOH should take it into consideration to provide the CHBCG’s organization with enough personal protective equipment for their safety and working without fear of being infected with deadly viruses. / NRF

PhD (Sociology) / Department of Sociology / The purpose of the study was to explore and understand the circumstances, which influence abused female breadwinners to stay in nuptial contracts and to model coping strategies for their plight. The study was qualitative in nature and an explorative case study design of abused married female breadwinners who had reported cases at Thohoyandou Victim Empowerment Programme (TVEP) trauma centers in the Vhembe District of Limpopo Province, South Africa was used. A critical case purposive sample was used to draw a cross-sectional sample of 12 participants from a total population of 1800 female breadwinners who reported cases between 2010 and 2015. The data collection methods were; in-depth interviews, focus group discussions from the same participants and key informants‟ interviews from three TVEP female managers. The three data collection techniques ensured triangulation for more complete and well-validated outcomes of the study. The data analysis method was the Van Mann. The study found out that a plethora of circumstances that involves the following; culture, the desire to take care of children, culture, religion, social needs, social status and entrapment influences abused married female breadwinners to stay in abusive marriages. As a result, they are forced to devise some coping strategies that include; problem solving strategies, reporting to the police, protection orders, seeking refuge, alcohol abuse and dependence, counselling, religious intervention, social support to cope with their plight. Establishing the reasons was critical in coming up with intervention methods that may help to curb abuse and coping strategies that may assist them in their plight. / NRF

PhD (Health Sciences ) / Department of Psychology / The rate of incarceration is historically high. Increasingly, research points to the negative effects of incarceration among offenders, particularly in adult facilities. Literature published since 2000 suggests that incarceration fails to meet the developmental and criminogenic needs of offenders and is limited in its ability to provide appropriate rehabilitation. Incarceration often results in negative behavioural and mental health consequences such as suicidal thoughts and attempts. Suicide is often the single most common cause of death in correctional settings. The psychological impact of incarceration and its implications for post-prison, free world adjustments are substantial. The severe behavioural problems of offenders are a result of complex and interactive individual and environmental factors which elicit and maintain offending behaviour. The study sought to develop a model to facilitate effective psychological services among offenders in long-term incarceration correctional services. The study consisted of two phases, namely the empirical phase and conceptualisation phase. In phase one, which was the empirical phase, a qualitative approach was employed. The study utilised phenomenological, explorative, and contextual designs. The study population comprised of male offenders who were serving their long-term incarceration in the Vhembe District at Limpopo Province. Thirty offenders and one clinical psychologist were purposively selected. Data were collected from participants using semi-structured interviews. In-depth information about their experiences physical and mental risks of being incarcerated, as well as the coping mechanisms they used during incarceration was collected. Unstructured interviews were used to collect information about psychological services that are being rendered at correctional centres and their effectives from the only psychologist who participated in the study. Field notes as well as observations were also used methods of data collection. Data analysis was done using Interpretative Phenomenological Analysis and Thematic data analysis. Relevant ethical principles were adhered to. Informed consent was sought from participants prior to the commencement of the study. The study further maintained the aspect of confidentiality and privacy since it was dealing with human subjects and sensitive issues. Issues of trustworthiness; credibility, dependability, transferability and conformability were ensured. The study findings revealed that most of the offenders were not very happy with the kind of mental health services they received from the correctional centres. They reported that correctional centres had a potential to make one totally insane. However, for one to make sense of what is happening at the correctional centres, one would need to receive mental vi health services. Furthermore, the study also discovered that one of the correctional centres is not providing offenders with mental health services and this makes it difficult for offenders to cope with their long-term incarceration since rehabilitation is not taking place. Findings also showed that offenders in one of the two centres were at a greater risk of contracting communicable diseases at the correctional centre due to overcrowding, poor health care system and poor hygiene. Concept analysis was done using Dickoff, James and Wiedenbach, (1968) guidelines. The framework adopted six guidelines that were used in theory development. A model was developed using the Walker and Avant (1995) framework to enhance the effectiveness of facilitation of psychological services at Thohoyandou correctional services and Kutama-Sinthumule Maximum correctional centre. The researcher recommends that mental health policies should be implemented to enhance and scale up mental health services in both correctional centres. / NRF

MCom (Business Information Systems) / Department of Business Information Systems / Today, information and communication technologies (ICT) have become an integral part of humans lives more especially in business, be it those in developed or developing countries. The evolution of ICT’s has also led to the introduction of e-Commerce services. Both the public and private sectors, develop these technologies with customer satisfaction in mind. Out of all the efforts by businesses and ICT experts, e-commerce systems continue to fail because of low user acceptance and user attitude, especially in developing nations. Security issues are known to be of top most concern for online shoppers. A survey was administered to 161 respondents, to find out how cyber security affects consumer’s intentions and actual use of e-commerce systems. The study encompasses both users of e-commerce systems and non-users of e-commerce systems across Vhembe district of Limpopo Province in South Africa. A quantitative research approach was used. The findings revealed that perceived security was the main concern for non-users of e-commerce intentions to use e-commerce systems because of lack of information and lack of trust on e-commerce systems. The study also revealed that users of e-commerce systems are still concerned about security, even though they intend to continue using e-commerce systems. For the success of e-commerce in rural communities, government needs to join hands with retailers and SME’s to start awareness campaigns that will clarify how e-commerce systems work and eradicate negative perception on e-commerce systems. / NRF

PhDENV (Geology) / Department of Mining and Environmental Geology / The study focused on the geology, structural setting and mineralisation of copper-sulphide deposits in the Musina area, located in the Central Zone of the Limpopo Mobile Belt of South Africa. The Messina copper deposits are located in the eastern part of Limpopo Province near the border with Zimbambwe. The deposits stretch from northeastern to southwestern direction for about 15 km. Previous copper mining in the area took place at Artonvilla, Messina, Harper, Campbell and Lilly copper deposits. The current study, however, focused on two main deposits, Campbell and Artonvilla. The origin, nature and mode of formation of the Cu-sulphide deposits in the Musina area have not been established with certainty. Two principal hypotheses on the origin of the Messina copper sulphide deposits have been proposed, viz; a magmatic-hydrothermal model, and meteoric waters model. Consequently, the mode of formation and mineralisation style of the Messina Cu-sulphide deposits remain contentious. Therefore, the main objective of the study was to investigate the nature and mode of formation of Cu-sulphide deposits in the Musina area. Different research methods have been applied in the current study so as to unpack the contradictory positions on the genesis of the Messina copper deposits. This included fieldwork, remote sensing data acquisition, laboratory work, and data analysis and interpretation. Fieldwork involved soil geochemical survey as well as rock and ore sampling within the study area. A total of 295 soil samples, 33 rock specimens and 21 ore samples were collected for laboratory investigation. Laboratory work consisted of a range of methods that included; geochemical analysis, petrographic and cathodoluminescence microscopy, ore mineralogy and ore microscopy, fluid inclusion geothermometry and isotope geochemistry. The work was done in different laboratories including: Mining and Environmental Geology Laboratory, Unviersity of Venda; Department of Geology Laboratory, University of Johannesburg; MINTEK Laboratory in Johannesburg; Société Générale de Surveillance Laboratory in Johannesburg, South Africa; Department of Applied Geology, Geoscience Institute, Göttingen University, Germany and Department of Geology, University of Georgia, Athens, United States of America. Remote sensing data was acquired from Southern Mapping Company, Johannesburg, South Africa. Interpretation of Remote sensing data was done at the University of Applied Sciences, Oswestfalen-Lippe, Germany. Data analysis and interpretation of laboratory results involved the use of: Desktop ArcGIS 10.4.1 for geochemical data interpretation; ENVI 5.1 and ArcGIS 10.4.1 Softwares for remote sensing data; and Triplot version 4.1.2 software for ternary plot for compositional variation of rocks. Soil geochemical survey revealed geochemical anomalies for Pb, Zn, Cu, As and Ni over the known copper deposits in the area as well as over six other areas that have not been associated with any sulphide mineralisation. Such new anomalous areas have been identified as target areas for future exploration of sulphide ore mineralisation. Petrographic studies of the rocks confirmed the host rocks to be amphibolite-quartz granulite, biotite-garnet-quartz granulite, amphibolite, quartzite, hornblende gneiss, quartzo-feldspathic gneiss, potassium-feldspathic gneiss and cal-silicate gneiss. These rocks were subjected to hydrothermal alteration during ore mineralisation within the area. It was further noted that epidote alteration was quite intensive in ore samples, while in unmineralised rock samples it was less intensive. Remote sensing data interpretation revealed spatial distribution and intensity of epidote alteration within the study area and in places coincided either with the known copper deposits or structural features, thus led to the identification of target areas for future mineral exploration in the Musina area. The current study established that the process of ore mineralisation in the Messina copper deposits took place in two distinct phases: first the formation of garnet, graphite, magnetite and hematite during regional metamorphism of the Limpopo Mobile Belt; and secondly, sulphide ore mineralisation resulting in the formation of copper ore comprising, veined, disseminated and brecciated ores. Sulphide ore mineralisation consisted mainly of pyrite, chalcopyrite, sphalerite, bornite, chalcocite and minor pyrrhotite and galena as well as traces of pentlandite, tennantite, mollybdenite, cobaltite and tetrahedrite. This confirms that the Messina copper deposits had complex sulphide ore mineralisation that is typical of hydrothermal mode of ore mineralisation from a magmatic source. The study further establishes the paragenitic sequence of ore mineralisation, comprising four stages: Stage I (Garnet- graphite – Fe oxides); stage II (Quartz- pyrite); stage III (Pyrite- sphalerite - chalcopyrite); and stage IV (Carbonates). Stage III represented the main stage of sulphide ore mineralisation in the area, while Stage IV comprising calcite, dolomite and ankarite marked the final stage of hydrothermal ore mineralisation. Paragenetic sequence identified three generations of quartz; first generation being associated with garnet, graphite, magnetite and hematite, second generation with pyrite and third generation with pyrite, sphalerite and chalcopyrite. Previous studies, however, indicated that there was only one generation of quartz that formed at the temperature between 210o to 150°C, but the current study established that the entrapment temperature of first generation quartz ranges from 315o to 200°C; second generation quartz from 235o to 135°C and third generation quartz from 240o to 115°C. At the same time, sulphur isotope investigation of chalcopyrite-pyrite pair from Campbell deposit registered a temperature of 359°C. The study therefore concluded that the temperature of ore formation within the Messina copper deposits ranged between 359°C and 115°C. The presence of halite and calcite as daughter minerals within the fluid inclusions was noted and this apparently is indicative of high salinity of fluid inclusions, which is considered as a product of direct exolution of crystalizing magma. Raman spectroscopy revealed the composition of gases in the fluid inclusions to be CH4 and N2 with 80% and 20% composition respectively, however, some inclusions were gas-poor. The presence of gases in the fluid inclusions is an indication that there was boiling at the time of entrapment. A narrow range of 34S values of -0.5 to 0.5‰ obtained in this study further confirms the magmatic source of Sulphur as Sulphur from the host rock was found to have high 𝛿34S value of 8.2‰. A genetic model for copper ore mineralisation within Musina area is proposed. The deposits are of polymetallic vein type that are genetically associated with porphyry copper deposits. According to this model, copper ore bodies were formed from hydrothermal fluids originating from magma and were epigenetic in nature. Geological structures in the area acted as conduits for hydrothermal fluids that resulted in the alteration of the host rocks and mineralisation of copper sulphide ore. Thus, the Messina coper deposits are of magmatic hydrothermal origin although the apparent location of a batholith is still unknown and the study recommends further viii research work on the location of the batholith that is presumed to have been the magmatic source. The study further recommend dating of later rocks as well as orebody s it is essential for understanding the process of ore formation in this area. For further exploration, areas that have undergone “moderate” to “high” degree of epidote alteration and lie in close proximity to geological structures such as faults and thrust folds that could have acted as conduits for hydrothermal fluids and resulted in sulphide ore mineralisation and registered high geochemical anomalies for Pb, Zn, As and Ni should be targeted. In support of further mineral exploration within the study area, the study recommend a detailed geostatistical application for the purpose of delineating homogeneous areas based on the combination of lineaments, interpolated soil geochemical maps and thematic maps. / NRF

MSc (Zoology) / Department of Zoology / Mopane worm (Gonimbrasia belina Westwood) is an indigenous edible insect that periodically has population eruptions in Mopane tree (Colosphermum mopane) dominated vegetation. This insect is a valuable source of food and has become an economic commodity for commercial harvesters. Despite its importance, little is known of the population dynamics of mopane worm. Considerable attention has been paid to the nutritional and social dimensions of mopane worm consumption. However, anecdotal evidence suggests there is a decline in the spatial extent of their distribution due to unsustainable utilization, land transformation, and commercialization. This is paralleled with a decrease of harvest yield, thereby affecting local communities, commercial harvesting operations, and market product availability. Partial domestication of this species may be a way of ensuring sustainable and reliable utilization of this edible insect because it improves natural survival rates. Here I explore mopane worm ecology by mainly focusing on understanding spatial structuring and the role of domestication in the development of sustainable harvest techniques of Mopane worms (G. belina). Spatial structuring of mopane worms was investigated at both a fine (10m x 10m) and medium-scale (1 km2) at sites with and without commercial harvesting. Mopane worm populations were experimentally treated through transplant experiments and manipulating access of predators to 1st – 3rd instar larvae. The role of tree characteristics (height, canopy volume and number of stems) on both spatial and experimental treatments were explored using generalized linear mixed models. Moran’s Eigenvector Maps (MEM’s) were used to represent spatial structures at various scales and the role of soil. Relative to control, seeding of worms was successful in establishing new populations in unoccupied areas while transplant and application of sleeve nets had no significant effect on larval survival. Populations at sites where no harvesting takes place were spatially structured, while this was not true where commercial harvesting takes place. Canopy volume also accounted for egg packets distribution although the relationship was ambiguous. The density of larvae increased with an increase in sodium concentration in soil. Seeding of the population provides a viable option for the sustainable utilization of mopane worms and educating people on how to domesticate mopane worms. This study also highlights that populations of mopane worms are not only clumped in time but also in space and at various spatial scales. / NRF

MENVSC / Department of Geography and Geo-Information Sciences / South Africa was badly affected by the recent 2015/16 severe drought. Water levels in dams declined drastically resulting in decimation of livestock herds and widespread crop failure. Mopani District Municipality is comprised of many agricultural activities that contribute to the economy and social development of the country. The study evaluated the nature of the drought hazard - its impacts, vulnerability and adaptation strategies employed by rural communities of Mopani District. The study used a mixed method approach with both quantitative and qualitative datasets. The district was divided into two distinct climatic areas, the eastern lowveld which includes the Greater-Giyani, Ba-Phalaborwa and Maruleng Local Municipalities and the western highveld which includes Greater- Tzaneen and Greater- Letaba Local Municipalities. Questionnaires were administered among community members whilst key informant interviews were conducted among relevant government and municipal officials. Anomalies in long term climate data were analysed to determine the frequency and intensity of drought in the district. Drought characterisation was done using a Standardised Precipitation and Evapotranspiration Index whilst vegetation anomaly maps, maize yields and dam level data were used to analyse the impacts of drought across the district. Levels of vulnerability to drought were determined using the Household Vulnerability Index. Spatially distinct patterns of drought conditions across the district were remarkable with wet conditions on the western highveld along the escarpment and harsh dry conditions towards the eastern lowveld. It was found that nearly half the time there is some form of drought or another in the district which may be linked to the remote El Nino phenomenon. Community vulnerabilities have a direct impact on human welfare and different strategies are employed to adapt to drought hazards both at community and district levels. The study showed a link between drought hazard extent and vulnerability. Community members are adapting using conservation agriculture, selling fire-wood, accessing boreholes and rearing chickens, amongst other means to survive in these harsh climatic conditions. Local government intervention strategies include supply of seeds and fertilisers, selling fodder at a cheaper price and supplying water using trucks. The findings of this study contribute to disaster risk reduction efforts in Mopani District Municipality / NRF
