  • Description: Energy security is critical to global economic development and agricultural activities. Electricity is one of the most beneficial types of energy for rural household livelihoods and smallholder producers in South Africa. This study aims to examine the effects of household agricultural income on the adoption of electrical appliances and energy security among agricultural households in Mnquma Local Municipality. The study employed primary data obtained from 224 households using simple random sampling technique across three electrification stages. Descriptive statistics, and binary logistic regression was used to determine the relationship between socio-economic and demographic characteristics of the household and the household agricultural income on the adoption of new electrical appliances and energy security across the three electrification stages. Descriptive statistics results indicated that non-electrified (67.1percent) and recently electrified (54.3percent) villages are dominated by female-headed households, while in electrified households there are more male head households (58.3percent). The results also show that among the households that have the highest total monthly income (greater than R15000), 34.5percent were electrified, 17.1 percent were recently electrified, and 4.3percent were non-electrified. The Binary logistic regression model's findings for the second objective revealed that household head factors such as age, monthly total household income, household size, and household agricultural income have significant effects on energy security. The study's findings revealed that household agricultural income has a significant impact at a 5 percent significant level on the adoption of electrical appliances. Binary logistic regression findings for the third objective revealed that on new electrical appliance adoption there was a significant effect of gender (at 5percent level), household size, energy security, and household agricultural income at a 1percent significance level. Binary logistic regression revealed that the coefficient of household size variable is positive and significant at a 1percent significant level on energy security and electrical appliance adoption. In this study, household agricultural income on the adoption of electrical appliances has been found to be the most critical factor influencing the energy security status of households among the selected rural households in Mnquma Local Municipality. As a result, policies must be put in place to facilitate access to electrical appliances through electrification programs, invention of affordable electric appliances, encourage participation in agricultural production and agricultural market access, that will provide households with social benefits. To improve energy security, electrical appliances should be simple to use and aid in the transition from biomass to electricity. , Thesis (MAgric) -- Faculty of Science and Agriculture, 2021

  • Description: The post-apartheid transformative agenda for local government in South Africa (SA) was built on a system of new key performance areas for public employees. The problems of accountability and transparency in local government finance management, as well as good governance and the capacity building of those public officials designated to support local development, were among them. Over the years, the conduct of public officials has received more scrutiny in the media as well as in academic research. Ethics management therefore, has garnered more attention as well especially in the fight against corruption. The premise is that, if ethics management can be institutionalised public officials can become more effective and discharge their duties with respect for public resources. The imperative for the implementation of an ethical framework was also based on the need to ensure inclusive development which can be enhanced by ensuring accountability by local government functionaries. In this regard, the conduct of municipal functionaries and its regulation based on the code of conduct takes centre stage. The study contextualises ethics management and its efficacy with specific reference to the code of conduct and its role in the prevalence of unethical conduct. The results reveal glaring inconsistencies in the implementation of the code of conduct and a myriad of challenges rendering ethics management ineffective. , Thesis (MA) (Administration) -- University of Fort Hare, 2021

  • Description: The critical analysis of gender war in the African context is not a new venture but it is rather a significant discussion to the development of gender and feminist theories. The primary focus of this study is to investigate the limitations to empowerment that African women face at the hands of a post-colonial patriarchal society like South Africa, exacerbated by the oppression and subjugation employed by patriarchal and cultural norms. Thus, the research provides a comparative analysis of three contemporary novels by award winning South African women writers in African literature: Sindiwe Magona, Cynthia Jele and Angela Makholwa. These three dedicated women writers examine the different ways in which African patriarchy and culture oppress professional, educated women. Their work portray gender and / or female oppression and the stereotypes experienced by African women in the context of post-colonial, heavily patriarchal South African society. Therefore, this study interrogates the experience of South African women, as explored in the texts, revealing the literary expressions of gender oppression as well as the possibilities of empowerment. In addition, the texts are analysed through the lens of the Feminist literary criticism theory, Gender studies and African feminism. Through the examination offered by these theories, the study focuses on the experiences of South African women, as expressed by the female characters in the selected texts, through a critical analysis of female oppression and resistance and on the idea that gender is constructed socially and culturally in the African context. As this project reveals, the problem arising within post-colonial South African society is that women are still oppressed and are seen as passive and submissive. As a result, patriarchal perspectives combined with women’s economic dependence on men, make reaching self-actualization a challenging and even terrifying experience, and is often impossible for most women to achieve. Thus, there is a need to understand the experiences of these women so that effective and culturally sensitive interventions can be implemented. The emergence of these renowned female South African writers together with the emancipation of African countries from colonial supremacy has opened a space for women to compensate for and correct the stereotyped female images in African literature and in post-colonial societies. Most contemporary African writers such as Chimamanda Ngozi Adichie, Tsitsi Dangarembga, Neshani Andreas, Sindiwe Magona, Cynthia Jele and Angela Makholwa have shown that women are seeking empowerment and liberation. Therefore, this study seeks to highlight such experiences through its critical interrogation of the writings of selected South African women writers and the exploration of their gender-based themes in order to inform and or inspire women empowerment. It is intended to broaden and encourage further academic discussion in the fields of Feminism literary criticism, Gender studies and African feminism as well as women’s literature within the African context. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2021

  • Description: Despite South Africa being a mineral resource-rich country, it has experienced low economic growth post-democracy era. The available literature suggests that fluctuations in global demand for commodities have harmed the production process of tradeable and non-tradable goods. Based on this, this dissertation examines the impact of export commodity price on GDP per capita in South Africa using quarterly data beginning from Q2 (April-June) 1990 to Q4 (Oct-Dec) 2018. The Johansen co-integration technique and the Vector Error Correction Method (VECM) were utilised to examine both the long and short-run relationships between the variables of interest. The outcome of the examination has revealed that export commodity price and government expenditure have a positive relationship with GDP per capita in the long run. However, net capital flows have a negative effect on GDP per capita in South Africa. In the short run, the empirical results also reveal that both net capital flows and government expenditure are negatively related to GDP per capita. Furthermore, policy action should be directed towards structural investment for the development of sustainable infrastructure projects within the commodity export sector based on the long-run relationship between commodity export prices and GDP per capita. , Thesis (MCom) (Economics) -- University of Fort Hare, 2021

  • Description: Financial inclusion is widely regarded as another conduit through which poverty can be alleviated. However, both theoretical and empirical literature does not reach consensus on the effect of financial inclusion on poverty. Against this background, the study empirically examines the effect of financial inclusion on poverty in selected Southern African Development Community (SADC) countries, which include (Botswana, Malawi, Mauritius, Namibia, South Africa, Tanzania, and Zambia). The author employs the Generalized Method of Moments (GMM) technique for the period 1980 to 2019. Based on the Financial Intermediation Theory and the Social Justice Theory: Tunnel effect, 5 different models were estimated. Variables used to capture the different dimensions of financial inclusion include ATMs per 1000km and Bank Accounts per 1000 adults as well as Bank’s private Credit to GDP and Commercial Bank branches per 1000 adults’. The control variables used in the study are; GDP per Capita, Government Consumption, Inflation and Education. Empirical results revealed that financial inclusion reduces the level of poverty in the selected SADC states. The results also revealed that GDP per capita and government spending have a negative effect on poverty in the region. An interesting finding, even though not the major focus of the study was the effect of education. The results revealed that lower levels of education may exacerbate the level of poverty in the region. At the same time, tertiary education was found to have a negative and significant effect on poverty. The empirical results imply that policy makers should center their focus on reforms that will ensure that more people are financially included in the region. Also policies promoting high growth levels and acquisition of higher levels of education should be pursued. , Thesis (MCom) (Economics) -- University of Fort Hare, 2021

  • Description: Ntabankulu extends from latitude 30° 51' 09"S to 31° 09' 10" S and from longitude 29° 06' 51"E to 29° 23' 49"E in the Eastern Cape Province of South Africa. Ntabankulu Local Municipality has 141 villages with 125 976 population size. About 36% of villages do not have water sources, 38% have partial functional water sources, 6% have non-functional water sources, and 20 % have reliable water sources, primarily rivers (Mnceba, Caba and Mzimvubu). Water is scarce in this area, especially in the dry season when perennial rivers and springs become dry. This research investigates groundwater potential zones and identifies suitable aquifers that can be developed to augment the water resources. The study involved: literature review, remote sensing, borehole and springs data, geological, petrographic and geophysical (gravity, magnetic and electrical resistivity) analyses. Each method has its purpose in finding the potential groundwater zones. Ntabankulu Local Municipality is located on the Karoo Supergroup in Ecca and Beaufort Group, Adelaide Subgroup and Balfour Formation. During field analysis, it was observed that this area consists of sandstone, shale and dolerite sills, dykes and complex rings. Fining up sequences, massive bedding, concretions, and spheroidal weathering were observed in sandstone, shale, and dolerite, respectively. Groundwater seepages are found within these structures. Sandstones are yellow due to the presence of limonite because of the continuous seepage. Red coloured laminated shale reflects that the rock has an iron oxidation state with hematite (Fe2O3) on the sediments. The Geographical Information Systems (GIS) method was used to extract lineaments. Lineaments dominate Ntabankulu with an NW-SE direction. Some of the lineaments are due to Karoo igneous intrusions, and others are due to neotectonic activities. Ntabankulu is located on the eastern and northern neotectonic belts. Geological maps and lineament maps were compared; it was observed that sandstones and shales are found on high liinament density areas. High yielding boreholes and springs coincide with lineaments, and some lineaments are faults. Hence areas that have high lineaments density could be groundwater potential zones. There are geological structures (faults, joints, and fractures) that are present. Systematic and non-systematic joints are found on sandstones which are due to extensional stress. These joints have been reactivated and acted as strike-slip faults. All these geological structures increase the porosity and permeability of the rocks. It was observed that the area of Ntabankulu consists of coarse-grained and medium-grained sandstone with quartz and orthoclase minerals. Dolerite consists of labradorite, clinopyroxene, olivine, oxide minerals with twinning formed during cooling and magma crystallisation. The gravity and magnetic methods were used to study the subsurface rock density contrasts and susceptibilities, respectively. The gravity and magnetic maps were generated in Geosoft Oasis 8.3 software. High gravity zones coincide with some of the mapped Karoo intrusions. Unmapped dolerite intrusions, lineaments and faults were inferred. The magnetic method delineated the subsurface structures (lineaments and faults), which are known to control groundwater accumulation. These structures and inferred dolerite intrusions helped in identifying groundwater potential zones. Groundwater potential zones were inferred in sedimentary rocks between dolerite intrusions and areas where sills and dykes intersect. A total of six vertical electrical soundings (VES) were conducted at Mzalwaneni and Tabankulu town areas using the Schlumberger configuration array with a maximum penetration depth of about 25- 33 m. The VES data were modelled in Winresist and Surfer 9 software to obtain 1D models and geoelectric sections, respectively. These 1D models have three layers with response curves of H-type. The top layer is about 0.4 - 0.7 m thick, with resistivity values from 12.3 – 1885.9 Ωm and is topsoil (sand and clay). The second layer of thickness 5.2 – 13.3 m has low resistivity values from 23.1- 44.9 Ωm. This layer is interpreted to be fractured shales and sandstones possibly containing water. The third layer of high resistivity values of 145.9 – 727.4 Ωm is inferred to be sandstone. The simultaneous interpretation of resistivity and normalised chargeability revealed that groundwater potential zones are characterised by low resistivity values and low normalised chargeability values for layers from 0.7 - 13.3 m depth. The groundwatwer in the area of Ntabankulu can be found on unconfined aquifers. , Thesis (MSc) -- Faculty of Science and Agriculture, 2021

  • Description: Water scarcity is a major challenge in many different countries, particularly arid and or semi-arid like South Africa. Wetlands are one of the freshwater ecosystems that may assist in alleviating water scarcity because they are valuable not only as a water source for humans but also as an ecosystem of animals and plant species. However, wetlands have been experiencing rapid rates of vulnerability/risk due to alterations by population growth leading to enhanced water demand, climate variability, and human activities leading to land cover/land-use changes. Geographical Information Systems (GIS) and Remote Sensing (RS) are less financially taxing methods useful in studying water scarcity, as shown in this study. The study begins with a literature review presentation based on a desk study from predominantly academic publications and additional municipal and consultancy reports on the wetland ecosystem’s vulnerability/risk and focuses on applying GIS & RS in related studies. After that, the study conducts a vulnerability assessment using the Ramsar Convention’s wetland vulnerability assessment using the theoretical framework stages using GIS and RS technologies. The study hypothesizes that water demand, climate variability, and land-use/cover changes (LULC) are the tri-factor responsible for wetland vulnerability. It begins the assessment by first quantifying wetland water demand using the wetland water budget, ecosystem services and the Penman-Montheith-FAO (ETo) evapotranspiration index. Secondly, objectively representing climate variability on wetland vulnerability using trend analysis to measure rainfall and temperature variability. Thirdly, reconstructing LULC changes from multi-date remotely sensed SPOT imagery over ten years from 2007 to 2017 to identify and monitor impacts of trends. The vulnerability was assessed through a Principle Component Analysis (PCA) that identified relevant variables and Multi-Criteria Evaluation (MCE) to evaluate the wetland’s exposure. The study concludes that there is evidence of a possible increase in water demand whilst climate variability, which is estimated to have a 39% contribution to the wetland dynamics, is characterised by a decrease in precipitation and an increase in temperatures. Lastly, LULC trends showed a marked increase in domestic and commercial farming, and farming has been identified as a wetland stressor of note. , Thesis (MPhil) -- Faculty of Science and Agriculture, 2021

  • Description: Low nitrogen stress tolerant Quality Protein Maize (QPM) genotypes will be of great benefit to farmers for increasing productivity in nitrogen depleted soils in the Eastern Cape (EC) Province, South Africa (SA). The current study evaluated: (i) QPM inbred lines for tolerance to low soil nitrogen, (ii) the Nitrogen Use Efficiency (NUE) of different QPM inbred lines, (iii) the combining ability of QPM genotypes for tolerance to low nitrogen, grain yield, and other agro-morphological traits, and (iv) the agro-morphological characteristics and adaptation of QPM hybrids to environments of different production potential in the Eastern Cape, South Africa. Thirty-two white-seeded QPM inbred lines obtained from CIMMYT-Zimbabwe and Quality Seeds (PTY) LTD were evaluated for tolerance to low soil nitrogen stress using two nitrogen (N) treatment levels: 0 kg N ha-1 and 30 kg N ha-1 under both glasshouse and field conditions at the Crop Research farm, University of Fort Hare, in two planting seasons. The study aimed at assessing the response of QPM inbred lines to low N, with a view to identifying low N tolerant types under both glasshouse and field conditions. Shoot length stress tolerance index (SHL STI) indicated lines L23, L29, L27, L13, L16, L17, L31, L14, L18 and L22 to be low soil N tolerant from the glasshouse study. From the field study, low N Stress Tolerance Index (STI) identified inbred lines L23, L31, L26, L28, L25, L29, L32, L4, L6, L3 and L2 as low soil N tolerant. These inbred lines also had high grain yields (GY) in the field under 0 kg N ha-1 (all ranked within the top ten except L2). They also had the potential for stable yields across environments considering their high Yield Stability Index (YSI), Mean Productivity (MP), Geometric Mean Productivity (GMP) and Stress Susceptibility Index (SSI) values. Both the glasshouse and field studies revealed inbred lines L22, L23, L26, L28, L25, L29 and L31 were common to both the glasshouse and field studies as being low soil N tolerant. These thirty-two parental QPM inbred lines were evaluated in the field for their nitrogen use efficiency (NUE) under five different nitrogen levels: 0, 30, 60, 90 and 120 kg N ha-1. The inbred lines studied under 0 kg N ha-1 and 30 kg N ha-1 indicated that N level expressed highly significant differences (P ≤ 0.001) for total nitrogen in biomass (Bio Total N), total nitrogen in grain (G Total N), grain yield (GY), nitrogen use efficiency (NUE) and almost all the indices estimated. The top six nutrient use efficient genotypes were L9, L14, L23, L25, L29 and L32 across N levels. However, the best and highest NUE was obtained from the lowest fertilizer dose, 30 kg N ha-1. Highly significant and positive correlation coefficients were found between Nitrogen Use Efficiency (NUE) and yield (+0.9), NUE and NUtE (+0.9), NUE and HI (Harvest Index) (+0.5), NUtE and yield (+0.99), HI and yield (+0.5) and NUtE and HI (+0.5). Thus, NUE, HI and NUtE could be good predictors of yield potential under low N soil conditions. Sixty-four testcross hybrids were generated from crossing these 32 QPM inbred lines with two QPM open pollinated varieties (OPVs) as testers in a line x tester design and were evaluated under 0 kg N ha-1 and 30 kg N ha-1 in the field. The objectives of the experiment were to: (i) identify high yielding hybrids with tolerance to low soil N in the EC; (ii) determine the combining abilities and mode of gene action for various traits under low and high nitrogen conditions; and (iii) group the inbred lines into heterotic groups for future use in the breeding program. Results revealed that under 30 kg N ha-1 (30N) condition, both additive and non-additive gene effects were observed with less importance of non-additive gene action for grain yield. Based on specific combining ability (SCA) effects, hybrids LNC22, LNC31, LOB22, LNC30, LNC29, LOB11, LNC18, LOB30, LOB19 and LNC24 showed outstanding performance under 0 kg N ha-1 (0N) condition with relatively acceptable SCA under 30N for yield. Inbred lines L6 (1.63), L22 (1.74), L29 (1.83) and L30 (1.24) showed positive and significant GCAs for grain yield under 0N. They were identified as the best combiners for grain yield as they were among the top ten performers for GCA under 0N. They can be very useful sources of low N tolerance genes. Two heterotic groups were formed under 0 kg N ha-1 and 30 kg N ha-1 conditions, and they will be useful for future hybrid development in the breeding program. Furthermore, these thirty-two QPM inbred lines were utilised as parental lines to generate seventy-six single cross hybrids. These single cross hybrids were evaluated across three environments of varying production potential in the Eastern Cape (EC), during the 2016/17 and 2017/18 summer seasons. Non-QPM hybrids namely PAN5Q649R and Phb31MO7BR, as well as QPM OPVs OBATANPA and Nelson's Choice were included in these preliminary variety trials (PVTs) as checks. Twenty-five hybrids expressing high values for the Smith – Hazel selection index were identified across sites over years. Among those hybrids were two checks, namely Q16 (PAN5Q649R) and Q33 (Phb31MO7BR). The top five high – yielding hybrids selected based on the selection index were considered to be the most productive, stable and adaptable based on the GGE biplot and AMMI stability values. None of these single cross hybrids over yielded the best hybrid check (Q16) in the current study. A high potential environment, Centane, was the ideal environments for evaluating genotypes in the present study. The studies showed inbred lines L22, L23, L26, L28, L25, L29 and L31 to be low N stress tolerant at 0 kg N ha-1 based on the low N stress tolerance indices under glasshouse and the field conditions; they were also among the top ten grain-yielders under field conditions at 0 kg N ha-1. Also, in the NUE study, they were found to be among the top ten most N-efficient inbred lines under low N soils, under 30 kg N ha-1, and were among the top twenty-four inbred lines with high NUE values across the N levels in the study. Inbred lines L29 and L22 also produced testcross hybrids that were among the top twenty based on GY under 0 kg N ha-1. The testcross hybrids produced from these inbred lines were also among the top twenty-five with outstanding SCA effects for GY. These inbred lines were also parental lines of some of the top twenty- five best hybrids selected based on the Smith – Hazel selection index in the PVT study. Inbred lines L22, L23, L26, L28, L25, L29 and L31 can therefore further be evaluated and used as sources of N-tolerance genes in QPM breeding programs. , Thesis (PhD) -- Faculty of Science and Agriculture, 2021

  • 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

  • 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
