- Description: PVsystem has recently emerged in South Africa as a way to curb the country’s persistent shortage of electricity. A wide effort for the past few decades have targeted at study, testing and demonstration of PV power systems which was established all over the country as an appropriate measure to tackle transportation, agriculture, industry, commercial as well as domestic activities. In view of these drives, both off-grid and grid-connected PV systems are being applied. However, operating a building with an off-grid system is one of the means to providing the possibility of energy access to places far away from the national grid. As an off-grid choice, 50 W SHS is being distributed to customers in distant rustic parts of the country where grid option is difficult to access. But the SHS of the stated capacity can barely generate 0.3 to 0.4 kWh of electric energy per day, even at the optimal solar radiations. In view of this, more efforts are directed at expanding the off-grid systems to accommodate large rural households in South Africa. This thesis is dedicated to a study on the various configurations and components of PV power plant as a way to enhance electricity generations in South Africa. To this effect, different power plants were considered at SolarWatt park, University of Fort Hare with the aim to conduct a comparative analysis of the charge controllers with respect to the charge and discharge rates of their respective batteries. The grid-connected PV power generation was classified into hybrid PV and grid-assisted PV, while off-grid is a BIPV. These power plants generations were installed for the purpose of research level with a total capacity of 11.4 kW. The off-grid system is made up of HIT modules, FlexMax80 charge controller, Victron energy inverter and M-Molar battery bank. The hybrid and grid-assisted systems each consist of 15 polycrystalline modules and Microcare charge controllers. In addition, hybrid comprises SMA Sunny Island inverter and Trojan battery bank whereas grid-assisted consist of Microcare inverter and Hoppercke battery bank. The first part of the experimental work was monitored, and the meteorological parameters which are ambient temperature, solar radiation, relative humidity and wind speed, were measured and evaluated while electrical parameters includes PV current and voltage, MPPT current and voltage, battery current and voltage and inverter current and voltage were also measured and evaluated in the second part of the experiment. This lasted for a period of four years, starting from 1st January 2017 to 31st December 2020. Similarly, the second aspect was to monitor the electrical performance of the three systems and was performed for a period of six months, starting from January to June 2019. During the second experiment, hybrid and grid-assisted systems were reconfigured to function as off-grid systems. Moreover, a detailed data acquisition system designed to measure and record both meteorological and electrical parameters affecting the performance of the systems. The electrical parameters include PV current and voltage, MPPT current, battery current and voltage and inverter current and voltage. Other parameters in the measurements are; inverter efficiency, active and apparent power, while meteorological parameters include; solar irradiance, ambient temperature, relative humidity, wind speed and direction. The meteorological results show that the maximum and minimum mean amount of global solar radiation was 7.34 kWh/m2/day in December and 3.03 kWh/m2/day in June, respectively, while the average radiation and temperature for the typical year were 4.98 kWh/m2/day and 16.88 oC respectively. The solar radiations obtained are within the range in major places in South Africa. Similarly, an average wind speed of 2.5 m/s is experienced in Alice in a year and average solar radiation of 606.06 W/m2 in summer and 346.17 W/m2 in winter. The three lead-acid battery systems monitored under the electrical aspect are M-Molar, Trojan and Hoppecke battery systems. It was established that the charging current decreases gradually from 27.7 to 18.5 A for the M-Molar while Hoppecke and Trojan deceased respectively from 15 to 10 A and 23 to 13 A at the end of each phase by charging it at the maximum power point of the PV array. It was equally found that the M-Molar battery current has the highest rate of charging and quickest rate of discharging in comparison to the other two batteries. Finally, from the results gotten from this research, we may propose that the solar PV system contributes significantly to the satisfaction of the needed electricity in South Africa. , Thesis (PhD) -- Faculty of Science and Agriculture, 2021

- Description: The purpose of this research study was to explore and describe the experiences of patients on short-term drug resistant TB treatment in a TB specialist hospital situated in Nelson Mandela District. Patients on XDR-TB treatment face many challenges which include side effects which they find hard to tolerate and they end up stopping the treatment. Socio-economic difficulties of concern include delayed social assistance from the government to support their families, particularly when they are breadwinners. A qualitative, descriptive, explorative contextual design was used in this research study. A non-probability convenience sampling method was employed. The target population for this study consisted of those DR-TB patients who were on short-term regimen and semi-structured individual interviews were conducted. There were twelve participants who voluntary participated in the research study although the first interview was a pilot study. Ethical principles were adhered to throughout the study. A total of seven themes and twenty-seven sub-themes arose during the data analysis and were fully discussed. Confidentiality and anonymity was ensured throughout this research. The research findings showed that the participants shared positive experiences in as far as being able to easily access the health care service. Most participants were moved through a range of emotions which included shock. They felt heartbroken about the devastation and the disruptive nature of this illness to themselves and their family lives and, more seriously, were fearful of the morbidity and mortality thoughts which pervaded their thoughts but their health improved when drug resistant TB treatment was initiated. Many of the participants found it easy to disclose to their friends as they knew they could count on their support at the best and worst of times in their treatment journey. In conclusion the participants provided suggestions regarding their support needs on the journey to recovery from DR-TB. The researcher provided certain recommendations as far as the challenges expressed by the participants and these will contribute to strengthening the DR-TB adherence strategies. , Thesis (MPH) -- Faculty of Health Sciences, 2021

- Description: The aim of the study was to explore the knowledge and attitudes of women in Caleb Motshabi location regarding cervical cancer and Papanicolaou (Pap) smear screening in order for district management to develop a health education programme on cervical cancer and the benefits of screening. Cervical cancer amongst women worldwide has been identified as the fourth most common cancer. A qualitative descriptive explorative contextual design was employed in this research study. A non-probability purposive sampling method was used. Women between the ages of 18-60 years’ old who reside in Caleb Motshabi location were the target population. Four focus group interviews were conducted. The groups consisted of four to six participants grouped together to discuss the matter. Ethical principles were maintained as well as the concept of trustworthiness throughout this study. Data analysis was done using Tesch’s approach to open coding in qualitative research. A total of seven themes and eight sub-themes arose during the analysis of the data and were completely discussed. The findings suggest that the majority of the participants were aware of cervical cancer and Pap smear, but they lacked knowledge of what cervical cancer is or its causes. Although some of the participants had done a Pap smear in their lifetime, knowledge about how and the reasons the procedure is done still lacked. The majority of participants had received information about Pap smear procedure from peers rather than from health care workers. A significant finding was the fact that the participants who had done the procedure were open to attending regular screenings since they had experience on how it is performed. In conclusion It was recommended that educational programmes relating to cervical cancer and Pap smear screening be intensified in the area. This can be done through increasing awareness programmes in the communities and during clinic visits. To try and increase the uptake of the Pap smear screening it was also recommended that mobile clinics should be introduced to encourage women in the communities. , Thesis (MPH) -- Faculty of Health Sciences, 2021

- Description: There is dearth of information in South Africa about the psychosocial challenges experienced by caregivers of mentally challenged children. This study addresses psychosocial experiences of caregivers, such as, scorning, isolation and anxiety, which affect their well-being in adverse ways, and that continues to be overlooked by professionals dealing with mental health. This study sought to explore psychosocial experiences of caregivers of mentally challenged children in Alice in the Eastern Cape in South Africa. The study intended to uncover the psychosocial wellbeing of caregivers of mentally challenged children. Secondly, it set out to highlight the coping mechanisms employed by caregivers of mentally challenged children to deal with their psychosocial experiences. Lastly, the study sought to examine policies, legislation and support services in place for psychosocial care of caregivers of mentally challenged children. The researcher adopted qualitative research methods. Snowball sampling was employed to recruit 15 caregivers of mentally challenged children in Alice. The age of the caregivers ranged between the ages of 20 and 65. In addition, purposive sampling was adopted to recruit six professionals working with mental health in Alice. All the participants were black Africans. The gender comprised of thirteen females and two males. Data was collected through the use of face-to-face, semi-structured individual interviews, one interview per research participant, with the caregivers of mentally challenged children, and through the use of one focus group discussion with professionals dealing with mental health. The researcher analysed data through thematic content analysis. The study findings indicate that caregivers of mentally challenged children experience the caregiving process negatively, with a lot of burden. It also appears that they do not cope positively with such experiences despite professionally-trained personnel that are obliged by the Social Assistance Act and other government policies to ensure that caregivers receive sufficient psychosocial services. Findings also indicate that there is very little that is done by the relevant professionals in ensuring that they render sufficient professional support services to caregivers, such as needs assessment and therapeutic services. In light of the findings, the study concludes that there is a need for continuous rendering of comprehensive psychosocial support services to the caregivers of mentally challenged children. It is also recommended that social workers empower caregivers for mentally challenged children so that they can function effectively in their communities. Further, the government needs to reinforce existing policies that afford these psychosocial services, such as Integrated National Strategy on Support Services to Children with Disabilities. Meaning, the government should take an oversite role of these policies and monitor whether they get implemented or not, especially at grassroots level. , Thesis (MSoc Sci) (Social Work) -- University of Fort Hare, 2021

- Description: The purpose of the study was to investigate the challenges faced by police retirees of the Eastern Cape, South Africa, and to contribute towards the establishment of a post-retirement programme that would assist retirees to experience satisfaction in retirement. Upon retirement, police officers leave a job of personified authority and responsibility and become civilians. Throughout their career, police officers work under strenuous shifts, exposure to violence and witness gruesome incidents. In some cases, they facilitate the arrest of their neighbours and even family members in conflict with the law. How they adjust in the communities when they retire has never been investigated in the Eastern Cape, a research gap this study intended to address. A qualitative research methodology and a case study design was adopted. The data were collected from 21 participants. Semi-structured interviews and observations were used as methods of data collection. The interpretivism paradigm informed data analysis process. The life course theory was used as a theoretical framework for this study. The findings of this study revealed that police retirees experience challenges that are different from other public servants and the South African Police Service (SAPS) does not have programmes to prepare employees for retirement. The study established that most of the retirees had not yet adjusted to retirement because of the challenges they faced. Among the unique challenges that they experience are psychological challenges such as post-traumatic stress disorder (PTSD) emanating from their daily exposure to gruesome incidents, violence and working under strenuous shifts. The study also revealed that the retirees experienced broken social support system (family), social rejection by their previous employer (SAPS), and the communities they are retiring in. Therefore, as a result of rejection they relocate and start a new life somewhere else, where they suffer loneliness. Neglect by the employer (SAPS) made them feel useless and unappreciated. It was also established that the handing back of police equipment and uniforms makes them feel a sense of loss of power and authority, which makes them feel unsafe. The feeling of insecurity become more intense when the people they arrested threaten revenge on them when they are on retirement. The study recommends commitment from different stakeholders to assist employees in SAPS to experience a smooth and rewarding transition towards retirement. These include a pre-retirement planning programme that will engage employees ten years before retirement and require the employer’s commitment, a transition programme, that will engage retirees during retirement and require commitment from the police medical aid (POLMED) and community policing forum involvement. Finally, the establishment of social support system in the post-retirement programme is required for the extension of employee health and wellness (EHW) services. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2021

Therefore, as a result of rejection they relocate and start a new life somewhere else, where they suffer loneliness. Neglect by the employer (SAPS) made them feel useless and unappreciated. It was also established that the handing back of police equipment and uniforms makes them feel a sense of loss of power and authority, which makes them feel unsafe. The feeling of insecurity become more intense when the people they arrested threaten revenge on them when they are on retirement. The study recommends commitment from different stakeholders to assist employees in SAPS to experience a smooth and rewarding transition towards retirement. These include a pre-retirement planning programme that will engage employees ten years before retirement and require the employer’s commitment, a transition programme, that will engage retirees during retirement and require commitment from the police medical aid (POLMED) and community policing forum involvement. Finally, the establishment of social support system in the post-retirement programme is required for the extension of employee health and wellness (EHW) services. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2021

- Description: Incarceration is a world-wide phenomenon. It is aimed at punishing those who are in conflict with the law while ensuring that they also undergo rehabilitation processes. Whereas one cannot argue that incarceration is inevitable for those in conflict with the law, it is essential to realise that, when a woman is incarcerated, the remaining family unit members are left behind to deal with all the effects of having a family member taken away. It has been observed that there is an increase in the number of incarcerated women. About two-thirds of incarcerated women reported having one or more minor children, and most of them have lived with their children before incarceration compared to 36% of men (Woodard & Copp, 2016). This study aimed to understand the effects of incarceration of women on the family system in Buffalo City Metropolitan Municipality (BCMM). The study discussed the effects of women incarceration on their children, spouses/partners and care-givers. The available support services were also explored and the coping mechanisms adopted by these families during this period of incarceration. The study utilised a case study research design which was explorative in nature. The data was collected using semi-structured interviews with 15 participants who included eight children, one spouse, one partner and five care-givers. Bowen’s family system’s theory (1978) was utilised as an epistemological framework for the study. The study's findings revealed that the incarceration of women has a negative impact on the family members left behind. This increases the chances of school drop-out, alternative care placement and even criminal involvement of children themselves. It was also discovered that financial difficulties, infidelity and lack of proper support systems for these families are a challenge that is directly associated with incarceration. The study recommended that more efforts should be made to provide support through governmental, non-governmental and communitybased interventions to the families of incarcerated women to prevent these unintended effects. , Thesis (MSW) -- Faculty of Social Sciences and Humanities, 2021

- Description: Coastal urban expansion is on an upward trajectory, which poses serious threats to ecosystem functioning, human wellbeing and the general environment across the globe. It is on this premise that this study brings to the fore the growing complexity of environmental sustainability problems in a former apartheid space, as characterized by coastal urbanization and the intricacies of vegetation conservation. Consequently, literature utilized for this study reveals that urban expansion has led to an uncontrolled threat to the coastal ecosystem, culminating in soil erosion, environmental pollution through illegal dumping of solid waste, loss of coastal vegetation to other land use types, among others. Therefore, constant monitoring of these spaces is needed due to their fragility, as they are pivotal in the earth-atmosphere processes to the benefit of the entire humanity. To this end, the current study offers critical analysis and insights about the South African coastal ecological space. The essence of using BCMM in its consideration as an ecological space and former apartheid territory brings to the fore a scientific explanation of the spatial configuration and changes in the CVEs of the study area during the post-colonial era. In the course of investigating this study, the Urban Green Sustainability (UGS) theory was adopted in the course of selecting the review of literature, methodological approach and analysis of results. A mixed methodological approach (qualitative, quantitative and geospatial techniques) was explored in data collection and analysis. 254 copies of the questionnaire were returned and analysed for this research. Results generated revealed by the BCMM respondents confirms the occurrence of uncontrolled urbanization, deforestation and crop cultivation as major causes of coastal vegetation loss. In the same vein, the LULC classification results revealed that about 466 km2 of forest vegetation has been lost in BCMM from 1998-2018. Also, LULC classification results were validated by performing the Normalized Difference Built-Up Index (NDBI), Normalized Difference Vegetative Index (NDVI), Kappa’s coefficient (k), coefficient of determination (R2) and Pearson’s Product Moment Correlation (P) tests. The results also revealed that the built-up area had increased from 194 km2 in 1998 to 814 km2 in 2008. Further, all statistical tests revealed very good and highly correlated overall classification accuracies (of R2=0.89 and P=0.86) during the study period (1998 – 2018). This study makes a clarion call towards the rehabilitation of degraded coastal environments and proffers solutions towards the actualization of environmentally sustainable CVEs which offers optimal ecosystem services. , Thesis (PhD) -- Faculty of Science and Agriculture, 2021

- Description: Zimbabwe is entering into an era of rapid population ageing and like many other countries in the developing world, the country appears to be oblivion or at least trivializing the importance of setting up systems and infrastructures to accommodate this impending demographic shift. This qualitative study explored the socioeconomic conditions faced by older persons in Dombotombo high density Suburb of Marondera in Zimbabwe. The study aimed to generate credible evidence to stimulate and provoke a serious discourse regarding the welfare of older persons both in the short and long term. The study was predicated on three fundamental objectives stated as: (i) To demonstrate the socioeconomic challenges encountered by older persons in Dombotombo high density suburb of Marondera in Zimbabwe, (ii) To determine the survival strategies used by the older persons in Dombotombo high density suburb of Marondera in Zimbabwe and (iii) To appraise the role played by the government and donor organizations in supporting the welfare of older persons in Dombotombo high density suburb of Marondera in Zimbabwe. Methodologically, the study was designed and undertaken using the qualitative research approach, design and techniques. The total sample size in the study was forty-eight (48) participants’ including twenty (20) older persons who took part in in-depth interviews, twentyfour (24) older persons who took part in three focus group discussions and four (4) key informants who took part in key informant interviews. All participants were purposively selected for inclusion in the study. Data for the study was collected through in-depth interviews, document analysis, focus group discussions and key informant interviews. Data collection was guided by predesigned in-depth interview and focus group discussion schedules which included a number of questions. Collected data sets were subjected to thematic data analysis. The study was convienecd through the lens of the Modernisation Theory of Ageing and the Social Exchange Theory of Ageing. Findings demonstrated that older persons in Dombotombo suburb of Marondera were not a homogenous group, they faced multiple socioeconomic conditions ranging from ageism, poverty, abuse, exploitation, geriatric related morbidities, vicarious bereavement, low coverage by social protection programmes, limited support from the government and donor communities. Amid these challenges, findings demonstrated that older persons in Dombotombo were not passive victims of their advanced ages and circumstances; rather, they had devised and embraced various socioeconomic, cultural and religious survival strategies. The study recommended the need for the government and its allied development partners to invest in geriatric welfare by setting up systems and mobilizing communities and families and other social institutions to be companionate and supportive of their ageing members. , Thesis (MSW) -- Faculty of Social Sciences and Humanities, 2021

- Description: The study area lies in the eastern portion of Raymond Mhlaba Local Municipality (RMLM), formerly known as Nkonkobe Local Municipality within the Eastern Cape Province of South Africa in the southeastern portion of the main Karoo Basin. Its northen part is mountainous with high altitude of about 1500 m with dense vegetation, whereas the southern part attains low altitude of about 600 m with sparse vegetation. The entire study area is covered on the surface by the Beaufort Group sediments comprised of three geological formations namely Middleton Formation, Balfour Formation members (Oudeberg, Daggaboersnek, Baberskrans, Elandsberg, and Pilangkloof), and the Katberg Formation. Karoo igneous bodies (dolerite dykes and sills) intruded the sediments causing fracturing. The area receives mean annual precipitation of about 54 mm. It is semi-arid to dry with insufficient surface water resources and hence the need for this research to explore for potential groundwater. Many techniques were employed to reveal the surface and subsurface geology, including groundwater potential areas using climate data, vegetation cover, borehole data analysis, geological field mapping, rock samples collection for petrographic analysis, a density-porosity determination, magnetic data analysis, and electrical resistivity tomography. The study area was divided into seven sub-regions, SR1 to SR7. The climate data showed that the area experiences high monthly average temperatures of about 21.6 °C during the summer, and is a semi-arid to dry region. Vegetation cover is dense in the mountainous northern part of the study area. It receives comparatively high rainfall, experiences less evapotranspiration than the southern part the low altitude, receives less rainfall, and has relatively high temperatures and evapotranspiration. A total of 385 boreholes from the Department Water and Sanitation were analysed and these showed that sub-regions SR1 up to SR7 had average borehole depths ranging from 51.9 to 67.7 m, water strike depths from 13.8 to 21.7 m and yields from 0.8 to 1.9 L/s. Sub-regions SR2, SR4, SR5, while SR7 have an average yield ≥ 1.4 L/s up to 1.9 L/s and are classified in this study as having a good or high groundwater yield potential. Fifteen thin sections were studied indicating that the Beaufort Group has mudstone, shale and fine-grained sandstone. The latter was dominant in the studied thin sections with 70 – 80 % quartz, 15 – 20 % groundmass, 5 – 10 % of feldspars, 2 – 5 % biotite, and some had vein like cracks filled with clay cement. Laboratory studies show average dry densities for the formations vary from 2.44 to 2.65 g/cm3, and porosities range from 1.6 to 4.0 %. Magnetic grid data obtained from the Council for Geoscience (CGS) were reduced to the pole, first vertical derivative and analytic signal maps were generated to delineate magnetic sources in the sediments. The magnetic anomalies showed lineaments and ring-shaped patterns that were interpreted to be due to Karoo dykes and sills, respectively. Some of these intrusions are mapped on the geological map and quite a number are not mapped as they are under sediment cover. The intrusions are important in groundwater exploration as they would have caused fracturing of surrounding formations causing increased secondary porosity and permeability. Further, they are groundwater localisers. Electrical resistivity tomography (ERT) was carried out at 12 selected sites using the dipoledipole and Wenner-Schlumberger arrays, with a maximum cable length of 360 m was used with an approximate maximum depth of investigation of 70 m. Most of the sites’ inverted models show a low resistivity top layer of about 10 m thickness, which is inferred to be topsoil with moisture/water and or clayey content. A high resistivity second layer underneath the top layer, and is interpreted to be slightly weathered sandstone at its top grading into compact sandstones at the bottom of the investigation depth. Four site results show models with an intermediate layer between the top and bottom layers consisting of moderate resistivity values due to mudstones. Most of the models have vertical, narrow, low resistivity zones extending from the surface to the bottom layer, interpreted as fracturing. The top layer could be an unconfined aquifer during the wet months but is likely to dry up during the dry, hot months. The inferred fractures that extend deeper from the surface could be good groundwater targets to drill boreholes. Dolerite intrusions can act as natural groundwater barriers depending on their orientation hence such structures are the main targets when searching for groundwater. Vegetation cover observed on satellite images of remote sensing can be used along with other techniques to explore for groundwater. It is recommended that future ERT surveys should measure both electrical resistivity and induced polarization chargeability to discriminate between water and clay influence. , Thesis (MSc) -- Faculty of Science and Agriculture, 2021

- Description: Household debt as a proportion of South African household disposable income remain alarmingly above 70 percent. Impliedly, the majority of households are spending the bulk of their income on servicing debt. This not only puts a strain on household welfare but also on economic growth as household spending is the major contributor to economic activity in the country. Based on this background, the study examines the dynamics of the South African household debt. The analysis was done both at the macro and individual/household level (micro). The macro-level data covered the period from 1994 to 2018 utilizing the Autoregressive Distributed Lag model. The empirical results indicated that there is both a long-term and short-term relationship between the variables of interest. The results further show that the majority of low-income households in South Africa borrow more, as a way to smoothen their consumption. Interest rate as the official instrument to counter borrowing was found to have a positive relationship with household debt, indicating that households borrow to settle the existing debt as interest rates increases. The dummy variable used to capture the credit regulations enactment/amendments was found to be insignificant in the long run. This suggests that credit regulations implemented in South Africa have not reduced the propensity to borrow. At a micro level, the National Income Dynamics Study (NIDS) data was used. Five waves of data were collected on the same individuals every 2 years. Panel regressions were employed in the analysis and the empirical results revealed that employment and income at the micro-level are found to be strong determinants of household debt. The results further showed that being a male and a white individual was positively associated with the likelihood of taking up more debt in general. On the other hand, the results indicated that being a black African is associated with a high likelihood of using services from most of the informal non-banking institutions. The results also revealed that the greater the education level of the head of the household, the higher the probability of taking more debt. One of the telltale signs of over-indebtedness is the persistence of debt, households respond to increased debt and their inability to repay it by increasing their borrowing. The study also investigated the transmission matrices of households in and out of debt. The results indicate a higher transition frequency in and out of debt on informal loans from the non-banking sector that is normally accessed by the poorer households, this could indicate debt entrapment and the persistence of debt at lower-income levels. Based on empirical results, the study recommended policies that would support consumption without necessarily increasing the credit appetite of household debt. Additional recommendations are those that support selective lending and the strengthening of the risk management of lending institutions. Furthermore, to combat the rising levels of household debt, several measures are proposed in the study. , Thesis (PhD) -- Faculty of Management and Commerce, 2021

- Description: The concept of food insecurity has evolved over the years. However, due to the increases in the rate of hunger and food insecurity in many countries of the world, this phenomenon has continued to give both government and private agencies a lot of concern. As it stands now, achieving food security in African countries remain a major task regardless of various efforts made by most of these countries to reduce food insecurity and the household’s welfare by extension. As a result of the importance of this discourse, the issue of food security is number 2 on the United Nations’ Sustainable Development Goals (SDGs). In South Africa, the rate of household food insecurity is still observed to be high, especially in the rural households. One of the most talked about way of combating food insecurity is through household farming. But food insecurity is believed to have affected the household’s level of productivity despite their commitment to improved welfare situation in the country. Consequently, this study sought to assess the impact rural household farming has on food insecurity in South Africa between the year 2009 and 2018. Using the South African General household survey, information on the household socioeconomics and demographic features were retrieved, as well as variables that are believed to impact the rural household agribusiness. In determining this, frequency counts, percentages, the logistic regression model was used. Also, the Household Food Insecurity Access Scale-score (HFIAS-score), multinomial logistic regression as well as the propensity score matching (PSM) was used in achieving the objectives of this research and the data was analysed with Microsoft Excel and STATA version 15. The result of the analysis showed that, the mean age of the household head is 53.96, 55.92, 56.65 for the year 2010, 2014 and 2018 respectively. Adding to that, the range of the households’ size ranged from 1 to 20 in the year 2010, 1 to 46 in the year 2014 and 1 to 20 in the year 2018. From the inferential statistic result, the gender of the household head is significant (p<0.000, 0.011, and 0.006) in determining household participation in agricultural activities for the years under review. The results of the PSM, using different matching methods reveals that the average treatment effect (ATT) of the impact of agricultural participation ranges from -0.121, -0.174, -0.132, and -0.106 in 2015; and -0.076, -0.173, -0.073, and -0.086 in the year 2018. This study therefore recommends that household farming should be encouraged by both private and public agencies as they contribute significantly to reduction in food insecurity. The transportation services in the rural areas should be examined in order to avoid situations that will lead to the increase in cost of transporting agricultural goods and services among the rural inhabitants. , Thesis (MSc) -- Faculty of Science and Agriculture, 2021

- Description: In South Africa, the compelling task of unmarried biological parents to provide financial support (in the form of paying monthly maintenance) to their children, as a matter of children’s rights, is intended to ensure the children’s economic and psychological well-being both in the present and future. This study seeks, within the private judicial system and socio-economic context, to explore the nature of children’s rights as they pertain to parental financial support and, the responsibilities of unmarried parents to provide financial support for their biological children until they become self-supporting. This is significant as many unmarried parents usually downplay their responsibilities towards ensuring the well-being of their minor children. Section 28 of the South African Constitution of 1996 enshrines it as a duty of parents to fulfil this aspect of their children’s fundamental rights and our courts apply these rules to the letter. The task of providing support to children basically rests with their birth parents as the primary care givers, and in the absence of these parents or, due to their inability, this legal obligation falls on the state. , Thesis (LLM) -- Faculty of Law, 2021

- Description: Ulwaluko (male initiation), one of the African traditions, which serves as transitional rite of passage from boyhood, has evolved over time, through the colonial era, apartheid regime and the current dispensation (Ntsebeza, 2004). Evidence indicates that within the South African context, the majority of candidates of Ulwaluko are males of school-going age. Ulwaluko is said to be a school where initiates are taught, yet there is no link between ulwaluko and formal schooling. Therefore, the study examines the extent to which School Governing Bodies (SGBs) conceptualize ulwaluko in the school-based policies. The study used theoretical lenses of Hall’s ‘Third Space’ or hybridity, as well as Decoloniality, qualitative approach, and a Case Study Design. For this study, two high schools were purposely sampled, with a total of twelve participants that included Principals, SGB Chairpersons, and SGB Educator Representatives, Representatives of Learners and Ordinary SGB members. In-depth interviews and document reviews were employed as research instruments. The findings of the study suggest that even though ulwaluko seemed to affect the management of the two schools, it was not explicitly addressed in their policies. Ulwaluko is reluctantly and cautiously addressed informally. Lastly, the schools were reportedly reluctant to open debates on how ulwaluko could be accommodated for fear of “contaminating” school protocols with the African culture, which they thought did not belong in schools. The study makes various suggestions to build a strong relationship between ulwaluko and formal school practices. One of the main recommendations is the integration of ulwaluko into the mainstream education system through school governance and school-based policy. The study also proposes a deconstructed leadership and management framework that places African cultural practices such as Ulwaluko into the mainstream of management and curriculum. , Thesis (PhD) -- Faculty of Education, 2021

- Description: This study was based on the GRED model and it sought to proffer solution to the challenges being faced by women sculptor entrepreneurs in Zimbabwe’s creative industry. The solution is set to help the policy makers, women in the creative industry and non-governmental organizations that work with women in the sculpting industry. The study’s main thrust was to create a gender responsive entrepreneurship development model for Zimbabwe’s creative industry. The entire study was anchored on determining the conceptual and contextual basis for a gender responsive approach to entrepreneurial development interventions, interrogating current government entrepreneurship approaches in Zimbabwe, determining important antecedents for entrepreneurship development that respond to gender dynamics within the creative industry in Zimbabwe and designing a GRED model for Zimbabwe’s creative industry basing on the findings of the research. The research employed qualitative research, through which focus group discussions, individual interviews, observations and document analysis were exploited for data collection. Armed with permission from UREC and the Ministries responsible for the creative industry, this study established that women in the creative industry were marginalized, poorly resourced and that government approaches and strategies were not being well implemented to benefit them. The study also revealed that most of the entrepreneurial activities were marred by corruption. The following tenets were recommended to foster viable women sculptors’ entrepreneurship: 50:50 representation, robust use of opportunities, business registration, forming of associations, funding, support, training, exhibitions, records keeping, monitoring and evaluation. The above tenets formed the basis of the constructed GRED model. , Thesis (PhD) -- Faculty of Management and Commerce, 2021

- Description: This study focused on the use of data from four wells (Ga-M1, Ga-S1, Ga-Z1, and Gb-J1) comprises of the Late Jurassic to Early Cretaceous shallow marine clastic sandstones consisting of wildcat wells located in Block 11 of the Pletmos Basin, a sub-basin of the Southern Outeniqua Basin, south offshore South Africa. This research evaluates the hydrocarbon potential in the Pletmos Basin by integrating core and well log data to characterize the source and reservoir rock potential. The methods implemented consist of a mineralogical and petrological analysis of about 300 thin section slides from four wells were studied. Stratigraphic profile computation from core logging, geochemistry analysis focusing on total organic carbon (TOC), geophysical wireline logs, conventional core analysis, geological well reports, and petrophysical analysis (water saturation, porosity, permeability, and volume of clay) were done using Interactive Petrophysics software. The different datasets were used to delineate how the mineralogy, total organic carbon content, poro-perm properties, fluid saturation, and volume of clay impact the hydrocarbon production potential. The evaluated sandstones have depths ranging from 2523.9 m to 3397.2 m with varying thickness depending on the position of the well. The results indicate that the study area consists of shallow marine clastic sandstones with sparse siltstones and mudstone that are fine-grained to silty in texture. The sedimentary sequence is characterized by moderate to intense bioturbation. Depositional environment was in a reducing condition indicated by plenty of glauconites. The tight fine-grained sandstones have low porosity values ranging from 4.5% to 13.8% in the selected intervals. The low porosity values may have been caused by the quartz cement that is observed from the thin sections. Low permeability values ranging from 0 mD to 0.16 mD are present throughout the studied wells caused by calcite cement and clay matrix. Source rock in the studied wells have inferior TOC values ranging from 0.31 wt% to 0.51 wt%. The van Krevelen indicates that the analysed samples have very low hydrogen index (HI) values and are consistent with Type III Kerogen (gas prone). A total of six reservoirs were identified. For well Ga-M1, one reservoir interval (2988.2 m – 30281 m) was selected and is located at BCII formation and was classified as a nonproducing reservoir due to its high water saturation content of 94.2%, even though it has an average porosity of 10.6%. Two reservoirs were selected for well Ga-S1, reservoir one (3026.3 m – 3107.7 m) is located within the 13AT1 formation and was classified as a producing reservoir with an average porosity of 11.9%, water saturation of 38.3%, and volume of clay of 29.5%. Reservoir 2 (3380.7 m – 3397.2 m) and the reservoirs (2970.20 m – 2993.0 m and 3006.80 m – 3049.50 m) from well Ga-Z1 located between the 9AT1 – BCVI formations were classified as non-reservoirs. One selected reservoir from well Gb-J1 had promising gas shows with an average porosity of 19%, water saturation value of 34.8%, and volume of shale of 33.1%. However, well Ga-S1 has a large interval with hydrocarbon potential compared to the well Gb-J1. Results indicate that the absence of hydrocarbon accumulation may result from non-effective seals due to the silty texture of the reservoir sandstones. Also, the presence of calcareous cement, clay minerals, and the argillaceous matrix reduce the porosity and permeability characteristics. To better understand the hydrocarbon potential of the Pletmos Basin, 3D seismic data is recommended to perform seismic well tie analysis for correlation between well log and seismic data to understand the basin‟s potential better. , Thesis (MSc) -- Faculty of Science and Agriculture, 2021

- Description: Deviant behaviour within the school setting poses a threat to the physical and social survival of individuals. Therefore, this study explored the dynamics of deviant behaviour among school learners in a selected boy’s high school in the Eastern Cape Province in South Africa. The study had the central aim of achieving the following specific objectives: (i) identify factors contributing to deviant behaviour among school learners, (ii) ascertain consequences of deviant behaviour among school learners, and (iii) establish preventative measures that should be employed to address deviant behaviour among school learners in a selected boy’s high school in the Eastern Cape Province in South Africa. The study utilised a qualitative research approach and a qualitative research paradigm in the form of case study research design. In terms of data collection, the study applied an in-depth one-on-one interviews and focus group discussions. Furthermore, the study employed non-probability sampling, specifically snowball sampling, and sampled twenty (20) participants. These comprised ten (10) learners, three (3) Life Orientation (LO) teachers and seven (7) key informants (School Governing Body (SGB) members and the school principal). In addition, the study employed a qualitative data analysis approach, with data being analysed thematically. The study established that there is no single cause of deviant behaviour among school learners but a series of distinct factors contributing towards deviant behaviour in various ways, such as use of drugs, low self-esteem, poor upbringing, and poor academic performance. Other factors included negative peer group influence, social media, and lack of self-discipline as well as lack of moral values and negative self-concept. The study concludes that through implementation of awareness campaigns, deviance policy, educational programmes, sport and recreational activities, safety and security, and social and behavioural change programmes, deviant behaviour can be addressed at school. Furthermore, it can be concluded that good behaviour among learners are central to effective teaching and learning at school; therefore, this should be inculcated in the learners. In light of the above findings, the Department of Education (DoE), policy makers, and school administrators should ensure that schools are provided with adequate facilities for teaching and learning, sports and recreational activities as well as information communication technologies and internet connectivity. School principals, members of School Governing Bodies (SGBs), teachers and parents should reduce deviant behaviour though increased supervision. , Thesis (MSoc) -- Faculty of Social Science and Humanities, 2021

Concerns are being raised that teacher preparation programmes are not adequately preparing trainee teachers for a holistic practice-based inclusive education. There is no agreement on the meaning of the concept of inclusive education. While some teacher educators resort to the traditional special needs education, others have adopted a paradigm shift to holistic inclusive education. The teacher education curriculum has not been aligned to teacher preparation for inclusive education. Trainee teachers go for teaching practice up to certification as qualified teachers without having acquired the skills and competencies for handling classrooms of learners with diverse educational needs. The study adopted pragmatism as the research paradigm, mixed-methods approach and QUAN-QUAL sequential explanatory triangulation of research designs; data collection instruments, data analysis and presentation of results were adopted. The researcher used stratified random sampling for quantitative data collection; and purposive, convenience, and snowball sampling for qualitative data collection. The total sample size was 210 trainee teachers and 20 teacher educators. Research instruments pilot-tested semi-structured questionnaires, semi-structured interviews, and documentary analysis. The internal consistency and validity of the instruments was checked using Cronbach’s alpha test and coefficients above 0.8 were obtained showing that the instruments were reliable and trustworthy. The results were that trainee teachers were inadequately prepared for inclusive educational practice. Teacher educators do not have the adequate subject and pedagogical content knowledge to prepare trainee teachers for inclusive education. Both teacher educators and their trainee teachers do not understand holistic practice-based inclusive education. The challenges in preparing trainee teachers for inclusive education include ignorance of inclusive education legislation, non-inclusive teacher education curriculum, and teacher educators’ lack of inclusive teacher preparation competencies, and shortage of financial and inclusive education material resources. Strategies to improve the quality of teacher preparation for inclusive education practices include policy and teacher education curriculum reforms, teacher educator empowerment, funding, and infrastructure development. The success of inclusive education largely depends on the collaboration between intellectuals, academia industry, governments and the community at large. The keywords are teacher preparation, inclusive education, teacher educator, and trainee teacher. , Thesis (PhD) -- Faculty of Education, 2021

- Description: Caregivers of children with Cerebral Palsy (CP) may experience some challenges and need support in caring for these children who present with a group of neurological disorders. Cerebral Palsy has been defined as a non-progressive condition of the brain, which results from interference during its development and affects body movement, muscle coordination, including motor and cognitive impairment. The objectives of the study were; to explore, describe, and interpret the experiences of caregivers of children with CP, to interpret the meaning attached to the experiences and interpret different support for caregivers of children with CP in Buffalo City Metropolitan Municipality, South. The University of Fort Hare Ethics Committee granted ethical approval. Informed consent was obtained from the participants before data collection. Ethical principles to be followed when conducting a research study has also been discussed with participants and ensured. An Interpretive Phenomenological Analysis (IPA) was chosen for the study. Four participants were chosen purposively in this study because IPA studies use a detailed account of individual experience. The data collection method used for this study is semi-structured interviews, which were done in the participant’s comfortable environment, and lasted between 40 to 60 minutes, using an interview guide. Data analysis has been done using the 7 steps noted in IPA. The main findings of the study are lived experiences of caregivers caring for children with CP. Participants experienced financial, physical, and psychological challenges in caring for children with CP. Caregivers also received communal support from different stakeholders. Support from family, their employers, other caregivers and the government through the multi-disciplinary team and the provision of social grants. Trustworthiness was ensured by observing the principles of transferability, credibility, confirmability and dependability. , Thesis (MNurs) -- Faculty of Health Sciences, 2021
