  • Description: Rural South Africa is faced with immense challenges including poverty, unemployment, low agriculture productivity, food and nutritional insecurity and inequalities. Against this background, enhancing rural agricultural productivity using proven technologies such as genetically modified (GM) maize production is suggested as a pathway to economic development and poverty reduction. Literature suggests that GM technology can increase crop yields, drought tolerance, reduced weeding labour costs and chemical spray costs. However, GM maize varieties available on the market currently were created to fit large-scale, capital-intensive, industrialised, and economically oriented agricultural systems. As a result, their uptake has been significantly slow especially in rural areas where several stakeholders are now questioning the potential of GM technology. With that background, this study aimed to understand determinants of gm maize production among rural farming households and their perceptions using the case of Ngqushwa Local Municipality. Specifically, the study sought to analyse types of maize varieties grown by rural households, associated yields, area allocation, rural households’ perceptions of GM maize, and to estimate factors that influence GM maize awareness, participation and intensity of production among this subsector. Using a cross-sectional survey research design, a sample size of 400 households was randomly selected and interviewed using a semi-structured questionnaire. The types of maize varieties grown by rural households, associated yields, area allocation and rural households’ perceptions of GM maize were analysed using descriptive statistics. Factors that influence GM maize awareness, participation, and intensity of production were estimated using a triple hurdle model where the 1st and 2nd hurdle were estimated using Probit regression, and 3rd hurdle a Tobit regression. The study revealed that landrace maize varieties are currently the most popular maize varieties grown by the majority of rural farming households from the study area producing higher yields (0.6t/ha) as compared to other hybrids (GM – 0.5t/ha, conventional hybrids -0.3t/ha and improved OPVs – 0.1t/ha). Descriptive statistics results also indicated that farming households from the study area allocated more land to landrace maize varieties (42percent) compared to other maize varieties (GM maize (30percent), hybrids (21percent) and improved OPVs (7percent) further supporting the notion that landrace maize varieties dominate the rural farming subsector. Perception results revealed that the majority (57percent) of the households perceived GM maize as an expensive variety which, however, has a potential to produce relatively higher yields than other hybrids on the market and eliminates several production problems (manual weeding, pest spraying) making farm management easier. Findings further indicate that the majority (52percent) of the farming households from the study area did not have sufficient knowledge of GM maize. Econometrics results revealed that GM maize awareness is negatively influenced by age and gender and positively influenced by marital status, employment status and number of years in school. Conditional on awareness of GM maize varieties, both participation and intensity of participation in GM maize production are positively influenced by land size, gender, group membership, size of arable land and negatively influenced by employment status and income. Against this background, the study concludes that farming households from the study area produced more compared to the other varieties. Furthermore, the study concludes that households get higher yields from landrace maize varieties and allocate more of their land to landrace maize production. In addition, the study also concludes that most rural farmers perceive participation in GM maize as beneficial especially towards elimination of farm management problems, produces higher yields, and makes farm management easier. Lastly, the study concludes that GM maize awareness is negatively influenced by age and gender and positively influenced by marital status, employment status and number of years in school. Both participation and intensity of participation in GM maize production are positively influenced by land size, gender, group membership, arable land and negatively influenced by employment status and income. The study recommends that priority should be given to these socio-economic and institutional factors and this may be addressed by targeting GM maize awareness campaigns and platforms more suited to female-headed, older, lowly educated and unemployed rural farming households. , Thesis (MSc) -- Faculty of Science and Agriculture, 2022

  • Description: Drinking water scarcity is a global crisis even though water covers about three quarters of the earth. One of the major causes of this scarcity is water pollution, which is a result of human activities. This has been noticed and reported for a number of years but is still unsolved and intensifying. Hence, scientists are busy trying to find solutions to this global menace. In this study, zinc oxide nanoparticles were synthesised via co-precipitation, a cost reasonable method and functionalized by grafting a pyrene ligand on its surface in order to provide a scaffold to which many other functionalities can be adsorbed. By so doing, the efficiency and capacity of bare nanoparticles is improved. The synthesised pyrene ligand was successfully characterised with nuclear magnetic resonance (NMR) and Fourier transform infrared spectroscope (FTIR). The adsorbent was characterized using X-ray diffractometer (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), FTIR, energy dispersive x-ray (EDX) and thermogravimetric analyzer (TGA). The choice of zinc oxide nanoparticles as preferred adsorbent was due to their exceptional properties including large surface area, thermal and chemical stabilities. These properties are the reason zinc oxide nanoparticles possess high adsorption efficiency and capacity. The results of characterization indicated a decreased particle size and improved thermal stabilities of the pyrene grafted zinc oxide nanoparticles compared to the zinc oxide nanoparticles, showing that this material can be employed even at higher temperatures. The average particle size of the bare nanoparticles decreased from 290 to 181 nm after functionalization. Thermal stability increased from 550oC in the bare nanoparticles to 650oC in the functionalized nanoparticles. Characteristic reflections of zinc oxide nanoparticles in the XRD analysis were maintained even after functionalization However, diffractogram roughness was noticed for the functionalized nanoparticles due to the introduction of the amorphous layer from the ligand. This novel material was employed for the removal of an herbicide, simazine as well as two dyes, methyl violet and brilliant green from aqueous solutions by batch adsorption experiments. The kinetics and isotherm studies of the different adsorption processes were carried out by using three of the commonly used kinetic and isotherm models (pseudo-first order, intraparticle diffusion and pseudo-second order) and (Langmuir, Temkin isotherms and Freundlich) respectively. From all batch adsorption experiments conducted for simazine removal, the adsorbent showed effectiveness and high adsorption capacity for the removal of simazine. The highest observed efficiency and capacity were 71.3 percent and 137 mg/g respectively at pH equals 2, time equals 60 minutes, adsorbent dose equals 20 mg and adsorbate conc equals 0. 281 mg/L. Kinetics study for the adsorption of simazine favoured pseudo-first order. However, Langmuir isotherm could also be applicable to understand the adsorption process. The material also showed reusability potential of up to three cycles for this contaminant indicating that this material can be re-used. In the case of the removal of methyl violet from aqueous solution, the adsorbent showed a reasonable adsorption maximum capacity (qmax) (31.5 mg/g) at contact time equals 360 min, adsorbent dose approximately equals 40 mg, temperature equals 20 plus 2oC and pH equals 6.5, when compared to other adsorbents previously reported for the removal of methyl violet (MV) in literature. Kinetics and isotherm studies indicated that the process for the removal of this pollutant with this pyrene grafted onto zinc oxide nanoparticles proceeded via pseudo-first order (R2 equals 0.931) and Langmuir isotherm models (R2 equals 0.980) respectively. These results indicated that this material could serve as alternate material to already established materials for the removal of recalcitrant organic pollutants from aqueous solutions. Moreover, the adsorbent also showed reusability potential for this contaminant. Similarly, the adsorbent showed high removal efficiency and capacity in all batch adsorption experiments for brilliant green (BG) adsorption. The highest adsorption efficiency of 88.8 percent was accomplished with 79.8 mg at pH 6.50 and temperature of 20 equals 2oC within 360 minutes. BG adsorption rate mechanism was best explained by the pseudo-first order kinetic model (R2 equals 0.903). Dye adsorption behaviour was best explained using Langmuir isotherm (R2 equals 0.980). Reusability of the adsorbent showed that the adsorbent is efficient after three runs. The overall results of adsorption by a way of comparison of the adsorption capacity of this novel material with respect to the contaminants is in this trend: brilliant green greater methyl violet greater simazine. This study indicates that this novel material can serve as new material for the removal of herbicides and dyes as well as vast variety of pollutants from wastewater considering its high adsorption efficiency and its recyclability. Thus, industries can explore the use of this material for the removal of varying pollutants from wastewater. , Thesis (MSc) -- Faculty of Science and Agriculture, 2022

  • Description: The aim of this research is to develop strategies that the DOH could put into place to improve its internal controls in financial management in order to contribute towards service delivery at Ngwelezane, Queen Nandi and Eshowe hospitals within King Cetshwayo District. The study used a mix of qualitative and quantitative study methods, however using one research instrument to collect both qualitative and quantitative data from 37 financial managers in these three hospitals. Data analysis using content analysis (of qualitative data) and percentage frequency analysis (of quantitative date) yielded study findings. This study found that financial managers are fairly competent regarding ‘effective communication’, ‘team work’, and ‘financial leadership’; the study results did not show respondents’ clear comprehension of Auditor General findings and processes followed to implement the recommendations in order to assess internal controls; and findings also indicate that financial managers meet objectives of financial management through cash flow, budget forecasts and expenditure. Developing a framework that will guide and monitor the application of financial strategies with the aim of improving service delivery will involve enhancing financial managers’ knowledge of District and Institution Service Delivery Plans, allocating resources properly and efficiently during the budgeting exercise, establishing internal strategies to maximise accountability and transparency, having fraud prevention strategies in these institution, and putting measures in place to be able to forecast budgetary adverse. It is recommended that the Executive Management facilitates strategic break-away sessions for the financial managers to workshop them on practical ways to improve the efficiency of financial management on public health service delivery, as outlined in this study. , Thesis (MPH) -- Faculty of Health Sciences, 2022

  • Description: New Public Management (NPM) is a new paradigm of public administration which highlights the failures and inadequacies of the public sector performance over time. NPM was developed in order to enhance performance and service delivery within the public sector through adopting principles of the public sector. The nature and process of the activities within the public sector and the traditional public administration have been seen as problematic. As such, the birth of NPM is grounded in the need to offer more efficient mechanisms for service delivery. This study aimed at assessing the implementation of NPM principles towards effective service delivery within the Eastern Cape government. The study was underpinned by the New Public Management Approach. A qualitative desktop review was adopted to find answers to research questions of the study. The data was evaluated qualitatively through thematic analysis. The study findings reveal that the Eastern Cape government is making strides to effectively implement NPM principles towards improving service delivery. The implemented principles are privatisation, managerialism, performance management, decentralisation and customer oriented. The effectiveness of strategies aimed at enhancing effective implementation of NPM principles for improved service delivery was also assessed. The findings show that the strategies are effective although there are some inherent issues that derail effective implementation. Poor reporting, corruption, poor management, shortage of trained managers and staff shortages were identified as challenges affecting effective implementation of NPM principles. The study recommends the need for effective implementation of anti-corruption policies as well as facilitating training and skills development. , Thesis (MPA) -- University of Fort Hare, 2022

  • Description: Threatened plant species are those species that are vulnerable or at the risk of extinction. According to Version 3.1 of the International Union for Conservation of Nature (IUCN)’s Red List Categories and Criteria, the three categories of threat in order of increasing risk of extinction are: Vulnerable (VU), Endangered (EN) and Critically Endangered (CR). These species are oftenly protected by both national and international obligations. Scientific evidence suggests that threatened plants are disappearing at an alarming rate. The current expansion of agricultural land, urbanization, over-exploitation of biological resources, climate change and invasive alien species are regarded as major drivers of biodiversity loss and high rate of species extinction worldwide. Scientists and conservation managers are seeking to understand and monitor plant species that are likely to be on the verge of extinction. Monitoring of threatened plants can be better achieved through insights about indigenous knowledge dynamics associated with such species. Scientific scholars including botanists, ethnobotanists, conservationists and anthropologists, all share common interest about the use of indigenous knowledge for livelihoods, scientific and economic growth. As a result, there is a growing interest on indigenous knowledge researches, particularly involving utilization and conservation of plant species. Given the fact that recent scientific evidence suggests that such studies are lacking in South African Biosphere Reserves, as well as the fact that scientist and conservation managers are seeking to understand species likely to be on the verge of extinction risk. It is within this context that this study is aimed at investigating threatened plant species utilization, conservation statuses and distribution in the Vhembe Biosphere Reserve, Limpopo Province in South Africa. The hypothesis of this study states that traditional knowledge about utilization, distribution and conservation statuses of threatened plant species provide suggestions for appropriate conservation practices. Since the current study is ethnobotanical in nature that is focusing on human interactions with plants, the research methods used addressed multidisciplinary aspects and involved disciplinary integration. An integrated participatory research approach focusing on shared learning, forging collaborative relations with participants, analyzing and validating the shared knowledge was used to document ethnobotanical data within the study area. This research approach was selected as it is considered to be a quick and effective way of acquiring data associated with indigenous knowledge systems. To offset the elements of bias during data collection, the research technique was designed to accommodate core principles that interlinked participatory rural appraisal (PRA) and rapid rural appraisal (RRA). Furthermore, the integrated core principles of participatory rural appraisal and rapid rural appraisal were used with conventional methods such as field surveys and interviews using questionnaires. Therefore, ethnobotanical data were collected through interviews with 203 participants. The data associated with threatened plant’s population size were gathered through literal counting of individual plants as per the IUCN’s Red List Criteria. Data associated with the conservation statuses were gathered from both the South African National Biodiversity Institute and IUCN databases. A total of 13 useful threatened plants belonging to 12 families were recorded with their conservation statuses ranging from being Vulnerable to Critically Endangered. The majority of the threatened plant species (46.0percent) were used for medicinal purposes only, followed by species used for medicinal purposes and as ornamentals (23.0percent). The frequently cited useful threatened species with use values (UV) > 0.024, relative frequency citation (RFC) > 0.059 and fidelity level percentage (FLpercent) > 5.911percent, included Asparagus sekukuniensis, Bowiea volubilis, Brackenridgea zanguebarica, Ocotea bullata, Rhynchosia vendae, Siphonochilus aethiopicus and Warburgia salutaris. About 47.0percent of the recorded useful threatened plants were distributed in remote areas of the Thathe Vonḓo and its surroundings. Threatened plants with population size < 100 adult individuals constituted the majority (61.54percent). Birdlime-making plant species were also documented in the current study. A total of 12 birdlime-making plants belonging to six families were recorded, including threatened Huernia nouhuysii, which is categorized as Vulnerable in South Africa. Amongst the recorded families, Loranthaceae and Euphorbiaceae were categorized as the most frequently utilized families. Among the recorded species, six of them were reported to being used in the birdlime-making for the first time and these species include Euphorbia pulvinata (17.2percent), followed by Tapinanthus forbesii (8percent), Tapinanthus rubromarginatus (7.2percent), Erianthemum ngamicum (7.2percent), Englerophytum magalismon-tanum (3.6percent), Huernia nouhuysii (2.0percent), and Euphorbia tirucalli (0.8percent). Only three plant parts were utilized for birdlime-making. The milky latex was preferred plant part (58.3percent), followed by fruit (33.3percent) and root bark (8.4percent). Birdlime-making techniques involved crushing, which accounted for 55.7percent, followed by air blown (29.6percent) and boiling (14.7percent). Furthermore, the complementary contribution of birdlime toward human development included, being used for bird hunting or trapping small birds (45.8percent), adhesion (23.2percent), teeth cleaning (17.2percent) and roof-waterproofing (13.8percent). The indigenous conservation strategies employed by participants included harvesting of single lateral root per individual medicinal plant (15.3percent), medicinal and timber materials are only harvested during winter season (16.7percent), the use of moist soil to cover injured plant part after bark harvest (18.2percent), prohibit harvesting of and/ or from an injured plant (11.8percent), collection of dried or fallen plants for firewood (8.4percent), issuing of permits by traditional council through the chief or headman to allow collection of medicinal materials and timber (9.9percent), prohibit chopping down of medicinal plant species (13.8percent) and collection of some Critically Endangered plant species such as Brackenridgea zanguebarica and Siphonochilus aethiopicus during the night by authorized people only (5.9percent). The hypothesis which stated that traditional knowledge about utilization, distribution and conservation statuses of threatened plant species provide suggestions for appropriate conservation practices can therefore, not be rejected as there is room for further and more detailed ethnobotanical investigations that is focused on human interactions with threatened plant species. The data presented in this thesis could be used as baseline information for formulating new conservation strategies, monitoring and management plans of threatened plant species not only in the Vhembe Biosphere Reserve, but in other regions of South African. This study provided insights associated with ethnomedicinal uses of Asparagus sekukuniensis, Protea laetans and Encephalartos hirsutus. Results of this study could also stimulate interest in other scientific disciplines such as the phytochemistry, pharmacology, bioprocessing, conservation and anthropology involving documentation threatened plant species. , Thesis (PhD) -- Faculty of Science and Agriculture, 2022

  • Description: South Africa has reformed its water governance to remedy the prominent disparities in water service provision that resulted from the legacy of apartheid. However, despite the new policy reforms and strategies adopted, inequities in water governance remain prevalent. Those residing in marginalised and poor rural areas are the most vulnerable and highly affected by this phenomenon. While this has been attributed to several factors, such as fragmentation of the water sector and lack of capacity, among other reasons, an analysis of the literature revealed that the absence of a water governance framework for social equity is highly prevalent in the context of Amathole District Municipality (ADM) where the research was conducted. Hence, the study's main objective was to develop a water governance framework for social equity that can be utilised to advise councils and policymakers on the attainment of social equity by water service providers at the local level. The study utilised the constructivist research philosophy by adopting a qualitative case study research design and an inductive research approach to address the research questions. Focus group discussions, semi-structured interviews, participant observations and document analysis were used to collect data. A total sample of thirty-four (n=34) participants was purposefully selected; twenty participants (n=20) participated in semi-structured interviews, while fourteen (n=14) participants were engaged through focus group discussions. Findings obtained from the thematic data analysis utilised revealed that while human rights principles and social equity values underpin South Africa’s water reforms, Amathole District Municipality is yet to fully absorb these foundational concepts into its water governance. The study revealed that this is largely attributed to a lack of meaningful participation, limited transparency and accountability in the processes and procedures of the municipality. Results also revealed that persistent inequities still exist in Amathole District Municipality as reflected by the unequal distribution of water services, inconsistency in services provision, lack of transparency and established procedures to guarantee procedural fairness and limited impact on interventions specifically in rural areas. Furthermore, the study revealed that the municipality’s efforts to address water inequities are highly undermined by various economic, environmental, socio- economic, and institutional governance factors. Therefore, the study recommended a Water Governance Framework for Social Equity (WGFSE) and proffered recommendations to enhance social equity for Amathole District Municipality and other municipalities with similar contexts. , Thesis (MPA) -- University of Fort Hare, 2021

  • Description: In the Eastern Cape of South Africa, rural small-scale farmers live in uncertain times characterized by climate change and variability, which intensify social, political and financial inequalities. Therefore, there is a need to increase the understanding and interpretation of climate information to minimize crop production risk, reduce rural small-scale farmers’ vulnerability to climate, and maximize opportunities. Increasing the resilience among rural small-scale farmers requires appropriate and viable practical approaches. By using systems thinking approach (and the Raymond Mhlaba Municipality in the Eastern Cape as a study area), this research disseminates the complex nature of current climate information frameworks. Through inputs from farmers (through a Farmers Research Group methodology) and climate data, this thesis developed a new framework for communicating climate information (herein referred as the climate information communication systems framework) to rural small-scale farmers. The proposed climate information communication systems framework successfully integrates scientific and traditional knowledge. The framework constitutes certain stages, where the farming system and crop identification is the first stage. The second stage is the requirements stage, which has two relationships: scientist to crop requirements and farmers to crop requirements. At the scientist to crop requirements level, users will examine crop requirements by combining climatic data and crop simulations, while at the farmers to crop requirement, rural small-scale farmers use the scientific information to plan for the farming season. The farmer then decides the planting and growing period as well as the harvest timing. The study suggests that building links between rural small-scale farmers, extension officers, and scientists makes sharing information easier. The proposed climate information framework design illustrates that stakeholders now have a personal relationship with climate information transmission and can influence the different actions to reduce the effect of climate change unpredictability. The study established that climate change and variability influence recent agricultural output trends. Recent temperature and rainfall trends could have resulted in low crop productivity in the study area. The study also reflected that women are a critical resource in agriculture and rural economy and that middle-aged men and youth are less interested in farming. The findings also showed that women are more receptive to climate information; hence, to promote access and use of climate information remains vital to consider gender-specific aspects for appropriate decision-making in the agriculture sector. The study also recommends enhancing the Farmers Research Group technique. In the past, the scope of this methodology has been narrowly focused, and it must be explored to incorporate additional types of climate information and more debate about how climate is related to the decisions farmers for implementation or consideration. , Thesis (PhD) -- Faculty of Science and Agriculture, 2022

  • Description: Aim: Over the last few years, there has been a significant increase in mental health challenges in adolescents, specifically anxiety and depression. There has thus been concern around what could be causing this increase. The present study therefore aimed to examine the link between maternal attachment and adolescent anxiety. Methodology: The research was conducted using a qualitative systematic review as the methodological approach. The sample included ten academic journal articles. These articles were searched using Google Scholar and The University of Fort Hare’s library database search engine. Final articles were selected based on the systematic review process of ensuring that the articles matched the inclusion criteria, centred on the main research question and sub-questions. Findings and Results: At the end of the systematic review process, the final literature articles were analysed using thematic analysis, which identified, analysed, and reported emerging themes. The study revealed that secure attachment and sensitive parenting buffer and protect against the risk and onset of anxiety and adolescent internalizing behaviours. The thematic analysis findings identified emerging themes based on the data analysis, which include: ‘Sensitive parenting as a buffer’, ‘Quality attachment protects’, ‘Safe haven’, ‘Insecure attachment precedes emotion regulation difficulties’, ‘Insecure attachment is associated with anxiety’, ‘Social problems,’ and ‘Negative parental-control undermines attachment security’. Conclusion and recommendations: The extracts provided by the literature were able to successfully give sufficient information to meet all of my study’s research objectives. The findings revealed that very few articles spoke about interventions that can be applied to assist in the development of healthy maternal attachment. Therefore, it is recommended that research be conducted on attachment-based interventions and building restorative adolescent attachment bonds. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2022

  • Description: The study seeks to analyse the link between monetary policy, domestic prices and exchange rate pass-through effect in South Africa. South Africa’s imports are more than its exports. Therefore, given a higher PTE associated with the importation of necessities, the poor are always left worse off since they are faced with imported inflation that is depreciating exchange rate driven. The Johansen co integration for the long run and the Vector Error Correctional Model for the short run were used to analyse monthly data obtained from the South African Reserve Bank (SARB) and the World Bank from 1990 to 2019. The study consisted of five separate but closely linked models, which are the price equation, excess demand equation, the monetary policy equation, pass through equation and the money demand equation. The results revealed that all models are cointegrated meaning that a long run relationship exist in these equations. However, the VECM short-run results show that two of the models have an ECM term which is negative and significant. The results indicated that there is evidence of the passthrough effect. In this case, a positive pass-through effect of 222 per cent was established between domestic prices and import prices. A pass-through effect of 39 per cent was also identified between imports and exchange rate and lastly a pass-through effect (PTE) of 30 percent was established between oil prices and import prices. , Thesis (MCom) (Economics) -- University of Fort Hare, 2022

  • Description: BACKGROUND: Staff turnover, defined as the total separations from employment, is expensive, can result in lost capacity, and can limit local health departments’ ability to respond to public health needs. Despite the importance of workforce capacity in public health, little is known about workforce turnover in local health departments. This study sought to determine the causes of high staff-turnover amongst professional nurses at selected health facilities in KwaZulu-Natal province and to identify corrective measures. Professional nurses are a critical staff category in any health organisation and make up the backbone of health care system. It is thus vital to ensure that this category is retained for the benefit of health services and its ultimate beneficiary, the patient. Furthermore, Personnel and Salaries System (PERSAL) statistics have shown that the hospitals selected for this study viz., Nkandla Local Municipality (LM) has more that two times (28%) the turnover rates (TORs) for PNs when compared to the district target of 11%, thus the decision to conduct this study at this particular municipality. METHODOLOGY: This research adopted a mixed methods retrospective study where both quantitative and qualitative approach was used to analyse data. The primary data source was the Exit Interview forms completed when a staff member resigns. It consists of three sections viz., section one contained demographics of each respondent with variables such as name PERSAL number, gender, rank, appointment and termination dates; section two contained closed ended statements on potential causes of termination where the respondent answered yes or no to statements such as offered senior position; and section three which was mostly qualitative information where respondents stated own additional views and comments regarding other causes of termination and recommended solutions. Both sections one and two were analysed using quantitative analysis while section three was analysed using qualitative analysis. Qualitative data from comments sections of the exit interview forms was thematically presented and analysed. These results were grouped into five themes namely; Career Progression, Management, Unacceptable or Poor Conditions of Service, Remuneration and Personal Issues. These previously completed exit interview forms were manually analysed in order to determine the causes of high staff-turnover amongst professional nurses at selected health facilities in KwaZulu-Natal province, during the period 2015-2016. Exit interview forms, previously completed by professional nurses for the period 2015 to 2016, were collected from both Nkandla LM district hospitals namely Ekombe and Nkandla. A self-designed spread sheet was used to collate the quantitative data from the exit interview forms which contained personal and demographic data (names, gender, PERSAL numbers, appointment and termination dates, rank, etc.), type of exit, and causes of exit, comments and proposed changes, following which it was manually analysed. RESULTS: A total of 54 participants completed the exit interview forms and selected the causes of service termination which were relevant to them. Ekombe Hospital participants were twelve (12) and Nkandla Hospital participants were forty two (42). Not all professional nurses who exited the service during the study period completed the exit interview form. The exit interview form completion rate was 78% (54/69). Twenty-four percent (13/54) of participants did not complete the exit interview form in full. The quantitative analysis revealed that the gender distribution of participants was mostly female, making 80% (43/54). The majority of participants, 30% (16/54), had 21-25 years’ service prior to exiting. On qualitative data analysis, the majority of participants selected unacceptable or poor conditions of service as the cause of service termination 65% (35/54) participants. This trend was also similar when each hospital participants’ selections were examined. In Ekombe Hospital 83% (10/12) participants’ selected unacceptable or poor conditions of service as the cause of service termination and in Nkandla Hospital this was 60% (25/42) participants. The majority of participants, 78% (42/54), stated that they still intended to re-join the department, and most were seeking employment in the public service. Furthermore, 70% (38/54), of the participants stated they would have stayed had their expectations been met. Further examination of themes and sub-themes derived from the qualitative data of the exit interview forms, the majority of comments, (20 comments), were related to Unacceptable or Poor Conditions of Service as the cause of termination. Sub themes analysis further identified resource shortages as the most common comments related to this determination. CONCLUSION: The leading causes of high staff-turnover amongst professional nurses at selected health facilities in KwaZulu-Natal province was determined to be unacceptable or poor conditions of service. On thematic analysis of qualitative data that emerged from the exit interview forms, the key areas that contributed to this determination included mainly resource constraints issues such as shortage of staff, shortage of equipment, shortage of funds, as well as poor infrastructure. Recommendations for staff retention and improvements in service conditions have been proposed. , Thesis (MPH) -- Faculty of Health Sciences, 2022

  • Description: The internet transformation over the past decade has changed the way businesses and consumers communicate. Instead of face-to-face transactions, businesses can now interact with their customers online, not just by marketing new products and services, but also by providing added value services in the online environment. The internet has become a dominant aspect in assisting businesses to attract and retain customers. One of the fastest growing platforms for this communication is through social networking sites. Many consumers are preferring to use social media platforms such as Facebook to express their views on the products or service of a business. In fact, the business’s Facebook page has become a preferred channel for customers who wish to voice concerns or complaints about the service they have received. As a result, many businesses are using that same platform for service recovery, and to make amends with their customers following a service failure. The aspect of online customer complaints and service recovery on social media, has not been well researched in the South African banking industry, which highlights both a gap and an opportunity. The aim of this study was to provide an analysis and categorisation of the types of customer complaints and service responses on the top five South African banks’ Facebook pages. These banks are; ABSA bank, Capitec Bank, First National Bank (FNB), Nedbank and Standard Bank. A qualitative approach known as netnography was adopted, as it provided an insider’s perspective on what customers complain about on a social media platform and how the banks responded to these complaints. 1250 complaints and the corresponding responses were extracted from each of the banks’ Facebook pages over a period of three months through a qualitative research software known as Nvivo 11. Using the framework provided by the justice theory, complaints and the corresponding responses were categorised. Customer complaints were categorised as either process, outcome or random and the banks’ responses were categorised as either procedural, interpersonal, distributional or informational dimensions. The main finding across all the banks, was that 1050 of the total number of complaints were related to the outcomes of the services provided; such as the banking app , the ATM machine and the general service the customers received. On average, the banks responded to around 70 percent of the 1250 complaints, with Nedbank having the best response rate (196/250) and Standard having the worst response rate (138/250). In addition, most of the banks responded in an interpersonal manner, dealing with customer’s problems directly. Once again, Standard Bank had the least number of interpersonal responses. On the whole, all the banks were mindful of the importance of explaining the reasons for service failures and explaining how the problem was going to be solved. Findings from this study indicate that consumer expectations of service failures and recovery are context driven, which requires companies to modify their recovery strategies to improve the customer’s personal experience. It can also be noted that many customer complaints stem from a general lack of understanding of banking systems and that banks should therefore be utilising their online platforms to keep customers well informed regarding common and frequent customer complaints. The main recommendation from the study is that banks should be entirely transparent during online service recovery and utilise their social media pages to do so. , Thesis (MCom) (Business Management) -- University of Fort Hare, 2022

  • Description: Background Drug-resistant Tuberculosis (DR-TB) is one of the main causes of global public health crisis, due to the morbidity and mortality rates associated with the disease. This DR TB is a complex illness having direct and indirect impact on finances, social functioning, and quality of life of infected individuals. Major research advances have been made in the diagnosis and treatment of DR-TB. However, minimal information exists on the socio-economic factors influencing the incidence and outcomes. This study aims to fill the gap by exploring the socio-economic factors from both the health care professional and patient perspective in particular settings to gain insights into developing context-specific strategies against the burden of DR-TB. Methodology The study applied a qualitative method to explore the socio-economic factors influencing MDR-TB through key-in-depth interviews (KIIs) and focus group discussions (FGDs). The study enrolled a total of thirty-two (32) consenting participants. The KIIs was conducted for ten (10) healthcare workers and nine (9) MDR-TB patients. Two focus group discussions were done involving seven (7) MDR TB patients and six (6) MDR-TB patients, respectively. The study targeted healthcare workers working in the MDR-TB field and TB patients with the following: GeneXpert Rifampicin resistance and patient confirmed as MDR TB. Eligible participants were selected using a purposive sampling technique from the hospitals` routine data electronic records (EDR-WEB database) and hardcopy registers (drug-resistant TB register) on MDR-TB patients enrolled in care at the study site. Informed consent was obtained from all study participants after thoroughly explaining the purpose. No personal information of participants was used. All responses from respondents were coded during analysis for autonomy and the respondents were not identifiable in any published or unpublished work following this research. The interviews were transcribed, some translated into English, where necessary, and analysed until saturation was reached. Data was coded and analysed using both thematic and content analysis technique. Results There were 3 main themes identified in the study: social factors, economic factors, and other contributing factors. 7 sub- themes were recorded under social factors and 2 subthemes under economic factors. Two independent factors that were also considered to impact MDR-TB were the attitude of healthcare workers, as well as the current COVID-19 pandemic. Conclusion MDR-TB is a major public health concern in the Makana Sub-district of the Eastern Cape. The findings of this study highlight the impact of socio- economic factors on the incidence, spread, defaulter rate and outcomes of MDR-TB. The social areas highlighted by the study participants as affecting the incidence and outcomes of MDR TB were housing and relocation, decreased immunity, stigma, patients’ attitude and lack of support, alcohol and other substance usage and prison/ incarceration. The economic factors identified by the participants were unemployment and job loss and health related expenses. Other factors are those factors contributing to the increased incidence and possible poor outcomes of MDR TB. Healthcare workers impact and attitude and the effects of the covid-19 pandemic were highlighted as additional factors influencing the incidence and outcomes of MDR TB. The management of MDR-TB requires rigorous efforts that should be directed at addressing the socio-economic factors. Therefore, future quantitative studies and important programmatic strategies should be considered to tackle the socio-economic challenges that contribute to the burden of MDR-TB infection in the Makana community. , Thesis (MPA) -- Faculty of Health Sciences, 2022

  • Description: Suicide is one of the leading causes of death among the youth and university students. The aim of this study was to explore knowledge that is available in published literature on suicide ideation and depression among university students in the South African context. This study utilised a systematic review in exploring suicide ideation and depression among university students so that knowledge and awareness about the prevalence of and factors associated with suicide ideation and depression among young people at university could be established. Method: A systematic review was the methodology used in the study. The main aim of the systematic review was to answer the research question that was formulated through the Patient of interest, Intervention, Comparison intervention and Outcome of interest (PICO) format. After the research question was formulated, 100 articles were collected through PsycInfo, Google Scholar, Ebscohost, Research Gate, and Taylor and Francis websites. From the 100 articles, five articles which met the inclusion criteria were selected with guidance from the Preferred Reporting Items for Systematic Reviews (PRISMA) flow chart. The Critical Appraisal Skills Programme (CASP) screening checklist was used to verify the eligibility of the five selected articles. Results: Three themes, which are effectiveness of psychological interventions, students who do not seek psychological interventions and decrease in suicide ideation and depression after intervention emerged from the eligible articles. The themes answered the research question and confirmed that psychological and psychosocial interventions decrease the rate of suicide ideation and depression among university students. The most effective interventions were individual therapy and online counselling. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2022

  • Description: This study aimed to investigate the factors associated with infant mortality in Sarah Baartman District hospitals. A quantitative descriptive case-control design was used to investigate and describe the association between maternal socio-demographic, infant, environmental factors, and infant mortality. A data abstraction instrument was used to identify cases and their controls, and to retrieve information related to antenatal and obstetric care for the mothers of both cases and controls, as well as some information related to perinatal care for both mother and infant, from the registers in the district hospitals in Sarah Baartman district for the financial years 2015/2016 to 2017/2018. This was followed by structured questionnaires which were hand-delivered, to the mothers of the cases and controls. This study showed that seven maternal socio-demographic factors (educational level, mother’s source of income, religion, where mother took sick child to, frequency of visits by a health care worker within the last one year, number of alive siblings, and history of intrauterine death) were significantly related to infant mortality among the study participants. Among the environmental factors, the type of house, availability of tap and type of toilet were significantly related to infant mortality among the study participants. The study recommends public policies concerning maternal health through targeting mothers for food supplementation and prenatal care to reduce infant mortality rates. Infant mortality in the study area can also be reduced by improving mother’s education because women’s education has spill over effects on fertility and maternal health care behaviour. , Thesis (MPH) -- Faculty of Health Sciences, Public Health, 2021

  • Description: Early childhood development is fundamental to human development and success in later life. Several stakeholders influence that development. Developmental policies are advocating for formal education provision at that early childhood age. Therefore, relationships and interactions of these stakeholders are of paramount importance in ensuring effective early childhood education provisioning – especially between parents and practitioners. Yet it has been reported that sharing of information concerning children’s educational development is not happening between parents and ECD practitioners. ECD centres are said to face many problems such as poor teaching and learning which may result in weak childhood educational development. Some of these challenges can be addressed through enhancing the partnership between parents and the ECD practitioners. The purpose of this study was therefore to explore the parents and practitioners’ partnership in early childhood education provisioning in ECD centres in the East London district. This study used the mixed method approach in the sampling, data collection and data analysis processes. The study focused on the partnership between parents and ECD practitioners, on how they work together, their views, how they communicate, on decision making and the strategies to enhance the partnership of parents and practitioners. Research questions in this study required both qualitative and quantitative data and analysis techniques. Quantitative data was collected from the ECD practitioners and principals by using questionnaires and qualitative data was collected through interviews with the parents. Quantitative data was analysed using SPSS and qualitative data was analysed using the thematic approach. The findings indicated that both parents and practitioners are working together in supporting learning and development. Parents are said to provide resources for use at the centre. Parents and practitioners are using different modes of communication for the learning and development of the children, including technology-based WhatsApp and emails. Practitioners are said to include parents in some decision making. The results indicated that even though some parents are working together with practitioners, while other parents are still showing ignorance and lack of knowledge on how they can partner for the educational development of the children. , Thesis (PhD) -- Faculty of Education, 2022

  • Description: Land reform contestation in South African reflects how restitution of lands has impacted the livelihoods of beneficiaries and the community at large. This study examines the restitution impact on the livelihood of Cata community members, a controversial land reform zone in Eastern Cape. Although the people of Cata suffered a loss of land through forced removal by the apartheid government, the ‘betterment planning’ by the state did not address their problem. The study investigates the extent of socioeconomic livelihood improvement that the land restitution policy has offered the people of Cata. The study explores the extent to which land restitution settlement has contributed to a sustainable development and how such development has impacted the everyday lives of the community. The study made use of qualitative approach for data collection. Interviews were conducted among land beneficiaries in Cata. These included land beneficiaries living in Cata and those who are also beneficiaries but were not presently living in Cata. To understand the state of developmental impact in the lives of Cata people, a focus-group discussion was organized to hear contributions from some community members. The study indicates that, financial compensation has not benefited many of the claimant. This is because many of the funds have not been put to good use considering the enormous socioeconomic challenges facing households. However, the formation of BRC brought some relief to the community members through helping beneficiaries by lodging their claims, helping with appropriate compensation awards and offering land restitution advice to claimants. The help from BRC has contributed to the developmental project that respondents attest has improved their livelihoods. , Thesis (MA) -- Faculty of Social Sciences and Humanities, 2021

  • Description: Access to cleaner water is essential to human health. The incidence of Antibiotic Resistant Bacteria ARB in drinking water and subsequent proliferation of Antibiotic Resistance Genes ARGs in drinking water is a concern for public health. The free DNA cassette harboring antibiotic resistance gene in drinking water has been linked with impaired public health. The ARGs allows bacteria to develop resistance towards antibiotics while ARB render antibiotics ineffective. Existing drinking water treatment technologies eg adsorption, ozonation and chlorination, have shown different levels of potency in the removal of conventional water pollutant. These technologies, which operating principles is based on oxidation or mass transfer, have been explored to gained an insight into their efficiency in the removal of ARB ARGs in water treatment. In general, methods that functions by mass transfer of the ARB ARGs is more effectively than bacteria oxidation. Consequently, adsorption technology was chosen using common metal oxide adsorbents. The adsorbents ZnOAg CeO2 and Al2O3 were synthesized via the self propagation combustion method. This method was selected because of the purity of the final product and the energy requirement. One of the challenges in the removal of ARB in drinking water is the release of ARGs. To address this concern, five different ZnOAg heterostructures were synthesized for the removal of Enterococci faecium. ZnOAg was chosen because of the bactericidal and bacteriostatic characteristics. The study revealed that the concentration of the precursors influences the microstructures of the adsorbents; however, it did not significantly affect the adsorption efficiency. The maximum adsorption capacity q34.11 CFUg was obtained for Ag1Zn3.5. The kinetic studies revealed that Ag1Zn1 and Ag1Zn2 adsorbents agreed to the pseudofirst-order kinetic equation and adsorbents Ag2Zn1 Ag3.5Zn1 and Ag1Zn3.5 agreed to the pseudo-second-order kinetic equation. Initial tap-water pH range was beneficial for the adsorption and the pH of the treated tap-water was within the WHO tap water recommendation 6.5 – 8.5 whereas the effect of ionic strength, anionic and cationic interference was insignificant in the adsorption of MDREF onto the different heterostructure. Interestingly the MDREF could retain its cell membrane integrity and resistance genes, suggesting that surface adsorption was the primary mechanism for the removal. Cerium IV oxide CeO2 was selected because of high adsorption towards phosphate, backbone base for DNA. To prevent the problem of antibiotic resistance, we have synthesized a CeO2 adsorbent that exhibit highly positive character in a wide pH range, via the simple self-propagation combustion protocol, for the removal of free DNA harboring antibiotic resistance genes. Molecular characterization of the extracted genes showed that the sizes for E. coli and inherent gyrB genes are 147 and 460 bp with a purity between 19 2.0. The XRD SEM TEM, and PZC results of the as-synthesized CeO2 showed an agglomerate of pure cubic-faced centered material and highly crystalline, with a net charge at pH 6.2. Experimental results revealed that the reaction proceeded via pseudo first-order kinetic, and it is governed by electrostatic attraction. The free- DNA solution pH electrolyte, and competing ions impacted on the adsorption process. Further experimental results showed that the as-synthesized CeO2 adsorbent has the potential to be used for the removal of free DNA harboring ARGs from tap-water even under oxic conditions. Alumina Al2O3 is an abundant adsorbent that has also shown high removal capacity towards phosphate. The highly pure synthesized Al2O3 adsorbent exhibit fluid-like behaviour under Scanning Electron Microscope SEM. The XRD pattern corresponds to αAl2O3. The adsorption kinetics was described by pseudo second orderadsorption capacity 11.7 μgg implying chemisorption, which agrees with the electrostatic force of attraction caused by opposing ions. This result was evident by the effect of different ions in the tap water. The synthesized α-Al2O3 has the potential for the removal of cell free DNA harbouring multiply resistant genes. , Thesis (MSc) -- Faculty of Science and Agriculture, 2022

  • Description: BACKGROUND: There is rising concern that kids are walking to school with too much weight on their backs. The weight of schoolchildren's backpacks is a persistent and divisive topic in the fields of education and health. Children who carry heavy backpacks are more likely to have back discomfort and musculoskeletal pain, which raises their risk of developing chronic back pain as adults. There is little research on this topic among South African school-age youngsters. The goal of the study was to find out how common low back and other musculoskeletal complaints were among primary school students who used a school bag. RESEARCH AIM: The purpose of the study was to identify the prevalence and location of musculoskeletal discomfort in primary school students in King William's Town, South Africa, and describe their link with backpack use. METHOD: In King Williams Town, Eastern Cape, South Africa, a descriptive cross-sectional survey was conducted among elementary school students between the ages of 9 and 14 years old. A systematic questionnaire and the Cornell Musculoskeletal Questionnaire were used to gather the data (body chart). Age, gender, and schoolbag details (style of backpack, carrying technique, and carrying time) were collected. The learner's waist, hip, and bag circumferences were all measured. On the data, descriptive and interferential statistics were used. FINDINGS: The study's conclusions showed that students' musculoskeletal pain was brought on by the weight of their backpacks or school bags. The majority of the students (89.8percent) complain about the difficulty they experience when lugging their heavy backpacks to class. In addition, 83.4percent of the students had bags that weighed more than 10percent of their body weight. Additionally, a sizable percentage of students (89.8percent) carry a hefty bag to school every day and report feeling fatigued while doing so (90.8percent). 90percent of the students reported feeling discomfort before, during, or after carrying their schoolbags. This pain is related with carrying a schoolbag. The majority of students (53.5percent) felt that their daily pain interferes with their ability to study. In order of severity, the majority of students report having discomfort in their shoulders (82.7percent), lower back (59.9percent), neck (47.0percent), upper back (40.7percent), and upper arm (16.4percent). CONCLUSION: According to the study, there is a link between students' musculoskeletal pain and carrying hefty backpacks or school bags. The shoulders are where musculoskeletal discomfort is most frequently felt. The study supported the findings of the majority of studies cited in the literature that most schoolchildren suffer from musculoskeletal pain because the weight of their backpacks is excessive compared to their size, weight, and age. RECOMMENDATIONS: The study produced a number of recommendations, including that the Department of Basic Education inform teachers, students, parents, guardians, and other key stakeholders about the effects of heavy backpacks or schoolbags on students' musculoskeletal pain. For students' convenience and to lighten the load on their school bags, locker rooms should be available. Teachers, parents, and guardians should also pay attention to the school bags that students are using to make sure that the weight is appropriate for their age and body size. , Thesis (MPA) -- Faculty of Health Sciences, 2022

  • Description: Wounds are usually accompanied by complications such as excessive bleeding and bacteria invasion. The design of wound dressings that rapidly stop excessive bleeding and inhibit bacterial invasion is crucial to promoting accelerated wound healing. To meet the abovementioned requirements in wound dressings, topical gels were prepared from sodium alginate SA and carboxymethylcellulose CMC. The wound dressings were loaded with an antifibrinolytic agent, tranexamic acid TA, essential oils, and a variety of metal-based nanoparticles, and carbon-based biomaterials. The scanning electron microscopy SEM and X-ray diffraction XRD confirmed the successful formation of the nanoparticles. The prepared formulations exhibited in vitro drug release kinetics that best fitted with the Korsmeyer-Peppas model. These gels exhibited good spreadability and viscosity, showing a shear-thinning behaviour with pH between 6.7 and 7.3, signifying suitability for skin application and ease of application. The prepared topical gels exhibited significant antibacterial effects against gram-negative and gram-positive strains of bacteria. SA EO-based formulations showed high antibacterial activity across all bacterial strains, followed by SA-based formulations compared to CMC-based formulations, which exhibited moderate antibacterial activity. Moreover, the prepared gels showed good cytocompatibility, promoted cell proliferation, and exhibited 80 percent wound closure on day 3 compared to the untreated group, which showed a 38 percent wound reduction in vitro. Excellent blood clotting properties were observed with CMC-based gels compared to other formulations. However, all the prepared formulations exhibited outstanding blood clotting ability compared to the control, showing that they can promote rapid blood coagulation. The features presented by the prepared gels reveal that they are suitable for rapid wound healing , Thesis (PhD) -- Faculty of Science and Agriculture, 2022
