- Description: Maize (Zea mays L) is an essential food grain crop in South Africa and is mainly grown under rainfed conditions by small-scale farmers. Quality Protein Maize (QPM) contains a higher level of two essential amino acids, tryptophan, and lysine when equated to normal maize. Therefore, the QPM in communities is a vital cereal where maize is a staple crop. Among the significant abiotic stresses that adversely affect maize productivity, such as soil fertility. Low soil pH or soil acidity results in nutrient deficiencies, as well as the toxicity of minerals such as manganese (Mn), aluminium (Al), and iron (Fe). The objectives of the study were to: (1) Characterize yellow QPM inbred lines and testcross hybrids for agro-morphological variability under optimum conditions, (2) Determine the response of QPM inbred lines and testcross hybrids to Al toxicity, and (3) Estimate the combining ability of QPM genotypes for the tolerance to Al toxicity. The laboratory assessment for tolerance to Al toxicity revealed a negative relationship between relative root growth RRG and hematoxylin staining; among the inbred lines, the genotype 8Y, 17Y, and 7Y had the highest RRG and net root growth (NRG) values and exhibited the highest tolerance to Al tolerance with the least hematoxylin staining. Inbred lines 12Y, 16Y, 19Y, 2Y, 20Y, 24Y, 30Y, 27Y, 34Y, 4Y, and 11Y were moderately tolerant. On the other hand, inbred lines 13Y, 18Y, and QSY5 had the least RRG were susceptible. Forty-four testcross hybrids were generated by crossing 22 QPM inbred lines with two open-pollinated variety (OPV) testers. These hybrids were evaluated together with five checks for different agronomic traits. The hybrids were planted in the summer season of 2017/18 and 2018/19 under rain-fed conditions 7 x 7 alpha lattice design was used. The significant variations among the genotypes for grain yield and most other agronomic traits under optimum, acidic conditions and across environments on combined analysis of variance. The hybrid was 14Y x NC (3.22 t/ha), followed by QSY5 x NC (3.02 t/ha) showed the highest yielding. The mean plant height was 226.23 cm, with ranges 197.60 to 254.85cm. The number of kernels per ear was 35, with a range from 29.45 to 40.25. Conversely, the mean ear length was 19.30 cm with a range of 17.65 to 20.95 cm, and the mean ear diameter ranged from 13,50 to 16,05 cm. The highest yielding hybrid, according to ranking, was 14Y x NC (2,93t/ha), which was ranked number 3, followed by 3Y x NC (2,83 t/ha), which was ranked number 4. Twenty-two yellow QPM inbred lines were evaluated for agro-morphological characteristics. A randomized complete block design with three replicates was used under acidic and normal soil conditions at two locations. The mean performance of inbred lines for grain yield ranged from 1.6 t/ha to 3.1 t/ha under optimum conditions, whereas it ranged from 1.1.t/ha to 1.7 t/ha under an acidic environment. The highest grain yielding genotypes under the optimum environment were 14Y, 7Y, and QSY5, while, in the acidic environment, the highest yielders were 3Y, QSY5, and 17Y. The lowest grain yielder under the optimum environment was 16Y at 1.5 t/ha, whereas 6Y, 7Y, 8Y, and 29Y were the most moderate yielders under the acidic environment. Grain yield displayed positive and significant (p<0,05) correlation with ear height (0.59), plant height (0.55), leaf length (0.18), number of leaves (0.37), number of ears per plot (0,54), number of kernels per row, number of rows per ear and thousand kernel weight. Combined ANOVA revealed that the environment effect was significant for all traits except the number of rows per ear and the number of ears in both environments. A total of 71 genotypes (22 inbred lines, forty-four single crosses, and five checks) were evaluated using a 7 x 7 alpha lattice design with two replications in combining ability. Across environments, the analysis showed a mean grain yield record of hybrids that ranged from 1.78 t/ha to 3.42 t/ha. Combined analysis showed only about 4 percent of the 44 hybrids had better grain yield than hybrid checks, whereas about 11 percent of the 44 hybrids had higher grain yield than two of the five hybrid checks. The highest yielding hybrid was 14Y x NC followed by QSY5 x NC. The Mid-parent heterosis (MPH) for grain yield ranged from -32.70 for 11YxObat to 16.50 percent for 14YxNC among the top-yielding genotypes. The highest positive mid-parent heterosis (MPH) for grain yield was observed in hybrid 14YxNC followed by QSY9xNC, QSY5xOBAT, 3YxNC, 13YxNC and 4YxOBAT, while the remaining hybrids exhibited negative estimates. Inbred lines' proportional contributions to the total variances were much higher than the testers for all traits. Whereas the inbred lines' proportional contribution was lower than the interaction of line x tester except on the number of ears which displayed the highest estimates of variances due to SCA effects, significant variation was observed. The GCA effects on grain yield in both environments generally showed no significant difference among inbred lines except for inbred lines such as QSY5 and 34Y but were positive. The selected crosses showed significant SCA effects in a few agronomic yield-related traits in the combined analysis. Among the hybrids, the only crosses that showed significant and positive SCA effects for grain yield were 25YxNC under optimum and 34YxObat under acidic environment. The inbred lines were assessed for tolerance to Al toxicity under laboratory conditions. Overall, the study identified soil acidity tolerant QPM inbred lines with an excellent combining ability for high-yielding QPM test hybrids, grain yield, and related traits. , Thesis (MSc) (Agriculture, Crop Science) -- University of Fort Hare, 2021

- Description: This study seeks to provide an in-depth description of the phenomenon of Child Sexual Abuse (CSA) and will be an addition to the existing body of knowledge. CSA is a complex phenomenon and despite it being a criminal act, incidences continue to increase globally. It has become a huge problem all over the world and South Africa is one of the leading countries with a higher prevalence. To gain understanding of this phenomenon and its prevalence in South Africa, a review of literature and analysis of the causes, types, diversity, and its effects were conducted. The analysis further provided a comprehensive account on how the adolescent survivor was affected by the CSA experiences and how she recovered from its effects. One participant was selected for the study and the purposive sampling technique was used for the process. The study made use of the General Systems Theory but narrowed it to the Family Systems Theory also known as the Bowen Family Systems Theory (BFST) as its theoretical framework. Systems theory was explored with a focus on families and communities and how each one contributes to the problem of CSA. The impacts of CSA on the survivor consisted of anger, poor scholastic performance marred future and broken relationships. , Thesis (MA) -- Faculty of Health Sciences, 2021

- Description: This study has analysed the Supply Chain Management (SCM) procedures in the Nelson Mandela Bay Municipality. Moreover, subsequent the research study provided a brief background on the local government SCM and the significance of the study which lies on its contribution in the improvement of SCM policies and procedures within the NMBMM. The problem that driven this study is the lack and inadequate use of SCM policies, procedures, practices, and systems in municipalities which that may lead to the misuse of public funds as well as poor service delivery. To address SCM issues in local government, SCM policy was adopted by the Cabinet of Republic of South Africa in 2003 as a way to address noted deficiencies in its public procurement processes within the SCM. This is in conjunction with the number of legislative frameworks were set to guide processes and procedures in this department. This research adopted the use of qualitative approach, for the purpose of this study it is the suitable approach due to time and resources efficiency, as it used desktop analysis and the secondary data which entails internet sources. Based on the literature review findings the study shows the application of six SCM elements, as outlined in the NMBMM SCM Policy. The recommendations of the study setting more emphasis on online tender application procedure. The effective employment of these recommendations can improve the processes and procedures in local government SCM, specifically NMBMM, and this can address the problem of lack of and inadequate use of SCM policies.

- Description: In South Africa, a severe shortage of professional engineers exists compared to the international benchmark of an average population per engineer. This shortage is one of the major causes of poor service and utility delivery at the municipal level. In addition, there is an insufficient number of competent engineers available for ongoing projects. Hence, there is a critical shortage of experienced, engineering professionals, particularly mid-career engineers to be responsible for production works. As a result, Universities of Technology (UoT) were tasked and authorised to train engineering professionals. From research, it was discovered that most of the Civil Engineering Graduate Technicians (CEGT) failed to acquire and develop relevant and essential industry skills during their engineering programme. This makes it difficult for them to be employed in the engineering workplaces. The departments of civil engineering in some South African universities have not evaluated the quality of the education of their CEGT and their employability to work in the engineering industry. This research therefore aims to measure the employability and quality of education of Civil Engineering Graduate Technicians from some South African universities by investigating the experiences of civil engineering alumni and employers of graduates in the engineering industry. This is to determine if the graduate technicians are provided and equipped with relevant industry competencies and skills set to meet the industry’s expectation. An online survey which contains 89 closed-ended questions was designed to allow alumni and their employers assess the standard of education of graduates and industry competence acquired during their engineering programmes. The Universal Resource Link (URL) to the online questionnaire was sent to a sample of 600 respondents using a web-based survey approach. Only seventeen percent of the targeted population completed the survey and that makes 102 respondents in this study. A conceptual model that measures the employability of Civil Engineering Graduate Technicians was also developed. The data gathered was statistically analysed. Varying descriptive and inferential statistics were explored, such as frequency distributions, central measure, dispersion measure, the Cronbach alpha coefficient test, one-sample t-tests, Cohen’s d, Pearson’s product moment correlation, ANOVA, MANOVA, ranking indices and lastly, Exploratory Factor Analysis (EFA). The EFA was employed to ensure the construct validity of the instrument and to identify items which should be removed. Each of these statistics cumulatively performs an empirical evaluation of the Civil Engineering Graduate Technician employability model. From the result of the data analysis, the hypothesised model identified the following factors as having an influence on the employability of Civil Engineering Graduate Technicians: Knowledge Gained, Academic Staff Teaching, Engineering Design Ability, Individual and Teamwork Ability, Participation of each Student, Infrastructure Provided, Problem Solving Skills, Professional and Technical Communication Skills, Workplace Practices, Encouragement in School and Essentiality of Creativity and Innovation. These eleven independent factors from Cronbach’s Alpha coefficient were all found to possess good internal reliability. They all exert a significant positive effect on employability. Additionally, managerial recommendations, limitations to the study and a call for future research were discussed. If these recommendations are implemented, UoTs and employers in the civil engineering industry should be successful in producing work-ready civil engineering technicians. Having these recommendations implemented is fundamental to creating innovative and skilled technicians and engineers in the engineering industry, who can adapt to market changes. Of the competencies assessed, “Individual and Teamwork ability” received the highest and “Infrastructure provided” the lowest rating. Overall, the results indicate that employers are reasonably satisfied with the competencies of Civil Engineering Graduate Technicians but point to the need for the strengthening of “Engineering design ability”, “Professional and technical communication skills” and “Infrastructure provided” competencies within the curriculum of the Diploma programme. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business Administration, 2021

- Description: The purpose of the study was to make an enquiry on the perceptions on female sterilisation adult participants, residing in Gunguluza Township, Uitenhage had. A qualitative research approach was used to collect the responses of 10 participants. These included eight women, one man and one traditional healer registered within the Traditional Healers Association of South Africa. The interviews had been semistructured with open-ended questions pre-set to help the researcher guide the conversation. Conversation analysis was the technique used to transform the information into research data that would attempt to answer the research question. The question this research attempted to answer was to form an understanding of how information and education resources provided by both Western and Traditional sources, including their availability and accessibility with regards to female sterilisation, as a form of contraception, have been understood, received and interpreted by adults residing in the research area of Gunguluza township. Gunguluza forms part of the area formally known as the Kwanobuhle 10 and Kwanobuhle 11 respectively. Some limitations, including limiting resources that resulted in only 10 participants being interviewed. The results had shown that participants had shown interest in acquiring more knowledge about female sterilisation and other reproductive health issues, in order to make informed decisions about their bodies, with contraceptive choice and use in particular. Most felt the need to engage with their partners about the choice of sterilisation largely due to the support they would need. With regard to traditional health as an alternative or interchangeable method of contraception, participants had very little knowledge of, with some expressing some importance and relevance in acquiring such knowledge, in a modern context. These findings came with sets of recommendations which placed an emphasis on the building of indigenous knowledge and its inclusion in formal spaces for open engagement and discussion. Traditional knowledge needed to be transferred from an oral to being documented into literature for future preservation and to eliminate any distortion. There was a gap for formal western medicine to collaborate or accommodate traditional medicine. The study made use of female sterilisation as a conceptual framework, with time and more future research could build and produce new theoretical understandings of the concept, from an Afrocentric context in particular. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2021

- Description: The Eastern Cape is one of the poorest provinces in South Africa. The level of poverty, and lack of basic resources has given way to inadequacies in many of the services available to communities. From improper infrastructure, to a flawed or lacking public education system. Past and future research into the inadequacies and inequity that exists in the public education system need to act as a catalyst to policy changes, and intervention implementations to solve the issues that continue to persist. This study focuses on the factors that influence the academic performance of learners in matric in King Williams Town. The importance of this research is to investigate the issues that negatively impact on the performance of Grade 12 learners at Breidbach High School. Further, the importance of this study is to share the findings of the research with community members as well as the Department of Basic Education with the view and hope that they will address these issues. The research question is: What are the factors influencing academic performance of Grade 12 learners at Breidbach High School in Breidbach outside King Williams Town? The research objectives are as follows: to investigate and highlight factors associated with poor academic performance in the participating high school at Breidbach in King Williams Town, to contribute within the anthropology of education, adding to an already existing body of knowledge, with specific reference to the participating high school in King William’s Town and to come up with the recommendations with the view of addressing some of the challenges faced by the participating high school in King Williams Town. The study followed a qualitative approach which included various techniques and ethical compliance was adhered to. For the proposed study, the researcher will use ‘academic performance’ as a guideline for the conceptual framework. , Thesis (MA) -- Faculty of Humanities, Department of Sociology and Anthropology, 2021

- Description: State-owned enterprises are facing several challenges. The challenges are associated with several risks in the business environment. Risk management has become increasingly important in the day to operations of any enterprise. This study is conducted to assess risk management implementation and execution within a state-owned enterprise (SOE). The main reason behind this research is that very little is known about risk management in the SOE sector in South Africa, as can be seen by the perpetual failure of these organisations. Therefore, this research focused on assessing the implementation and execution of risk management at Transnet Engineering because it continues to suffer losses as a result of “state capture”. The study sought to find out the role of organisational culture on the adoption of risk management in a state-owned enterprise. the main objectives of the research focused on the impact of commitment on the adoption of risk management in a state-owned enterprise; the function of implementation on the adoption of risk management in a state-owned enterprise; and the impact of monitoring on the adoption of risk management in a state-owned enterprise. A qualitative research methodology was utilised to attain results for these research objectives.The areas focused on Transnet Engineering with it regions and excluded other subdivisions of Transnet such as Transnet National Ports Authority, Freight rail, Port Terminals Pipelines and Properties. Convenience sampling was used to select 10 appropriate participants who were willing to provide the needed information to furnish the study’s findings. Interviews were utilised to collect data for this study. The data that was collected in this study was analysed using thematic analysis. The main findings of this study show that the organisational culture of Transnet Engineering is not enhancing the adoption and implementation of Enterprise Risk Management (ERM). , Thesis (MBA) -- Faculty of Business and Economic Sciences, NMMU Business School, 2021

- Description: Nurses are health care professionals whose duty it is to protect patients from acquiring infections while hospitalised in a health care setup. By maintaining an infection-free environment, it is expected that the patient's recovery will be promoted, and high-quality nursing care will be delivered. This also applies to the prevention of catheter-related bloodstream infections (CRBSIs) in haemodialysis patients. As nurses spend most of their nursing time with patients, they should have a good level of understanding of infection prevention and control in health care setups. In Eswatini, central venous catheters (CVCs) are commonly used for vascular access in patients who require haemodialysis. From the latest data available in the country's three largest regional hospitals, the proportion of haemodialysis patients with CVCs hospitalised for CRBSIs was 27% (64/239) January to December 2020. Further, it is unclear whether professional nurses have knowledge on the prevention of CRBSIs. This study aimed to investigate the effect of an educational intervention, based on the Centre for Disease Control (CDC) Guidelines, on professional nurses' knowledge regarding the prevention of CRBSIs in haemodialysis patients in hospitals in Eswatini (previously known as Swaziland). The study used a convenience sample including all professional nurses and nurse managers (N=99) employed at the renal and intensive care units (ICUs) at the five hospitals (Hospitals A-E) in Eswatini where haemolysis is conducted. The study is underpinned by Florence Nightingale's Theory and the Knowledge-to-Action Framework. The research study followed a positivistic, quantitative research paradigm, using a quasi-experimental, one-group, pre-post-test design with an interventional research approach, to be conducted in three phases. The first phase was the distribution of a pre-test questionnaire to all professional nurses and nurse managers working in renal units and those in ICUs that are also managing CVCs in order to assess their knowledge regarding the prevention of CRBSIs in haemodialysis patients. The second phase included the educational intervention, which was developed, reviewed and presented by the researcher to professional nurses. The third phase included the distribution of a post-test questionnaire to the professional nurses to assess the effect of the educational intervention on their knowledge.The pre-and post-test questionnaires were developed by the researcher, in line with the educational intervention (and informed based on the pre-test findings), reviewed by six experts and pilot tested to ascertain its validity and reliability. The researcher captured the data using Microsoft Excel and, with the assistance of a statistician, who performed statistical analyses using Cronbach's alpha, One-sample t-tests, Cohen's Kappa, Cohen's D, and Chi-square test. Ethical principles, according to the Belmont Report, including autonomy, beneficence and justice, and appropriate standards of rigour were maintained throughout the research study. In this study the overall knowledge was good with a mean score of 75.05 ±8.74 for the pre-test and 77.75±9.55 for the post-test. The knowledge scores for the factor infection prevention was higher (pre-test: 83.33±9.28 versus post-test: 85.14±8.28) compared to the factor catheter care (pre-test: 66.76±13.13 versus post-test: 70.38±14.27). The factor catheter care and age was significantly related in the pre-test with a p-value of .043 between groups. The factor infection prevention and how long practising in the unit were significantly related in the pre-test, with a p-value of .029 between groups. The factor infection prevention in the pre-test had a medium significant difference between >1 year and >5 years practicing in the unit (Scheffé p .048 and Cohen's d 0.77). The study is the first in the field of nursing in Eswatini. The educational intervention can be used by nurses in renal units and ICUs to close knowledge-practice gaps that can put patients at higher risk for CRBSIs, but requires further development and testing. , Thesis (MN) -- Faculty of Health Sciences, 2021

- Description: This study aims to establish clients’ preference for particular communication channels of a particular bank in Alice. The study, focusing on marketing communication, was guided by the tenets of media richness theory. The study employed both quantitative and qualitative research methods. This particular bank is one of the biggest banks in South Africa and it has many branches across the country and abroad. However, this study only focused on clients in the small town of Alice in the Eastern Cape. Alice has three major groups of clients: those who are highly educated, those who are illiterate and those who fall in between. This diversity in the demographics of the clients affects the way people react to the communication channels used by this bank including modern communication channels and traditional channels. It was discovered that education level, age (as related to literacy level), language, geographical location and access to computers and the internet have an impact on the way the clients evaluate the preference for particular communication channels of this bank. The results of the study show that the majority of the clients prefer communication channels that are interactive like face-to-face communication and cell phone calls. The other channels at the clients’ disposal are television, radio, newspapers, printed mail, internet and emails. However, some of these channels are not regarded as very effective by the clients in Alice for several reasons such as the rural nature of Alice, lack of access and resources, being illiterate, and a lack of education. The clients suggested that the bank make use of other communication channels that suit a rural and less developed area in order to effectively communicate with the clients. The study also brought to light that the use of the new ICTs in Alice is still lagging, resulting in many customers experiencing problems when they want to use some of the communication channels offered by the bank. , Thesis (MSoc ) -- Faculty of Social Sciences & Humanities, 2021

- Description: The successful prosecution of a sex crime case is dependent on the testimony of the victim. Due to the concealed nature of a sexual crime, it is notoriously difficult to prosecute effectively. With child victims, a number of additional obstacles present themselves when it comes to children giving evidence. Attrition is the rate at which cases do not proceed to court. Statistics in South Africa has revealed that rape has one of the lowest conviction rates of all serious crimes. This study is aimed at analysing the factors that cause attrition during the investigation stage in cases where children were victims of any form of sexual crime. In order to obtain the unscripted view of the investigation process, the qualitative study comprises of interviews with investigating officers who investigate these cases and the prosecutors who present these cases to court. The multi-disciplinary team-approach during investigation and its varying limits and challenges, were the main focus. A purposive non-probability sampling technique was utilised, focusing on the Kouga district municipality of the Eastern Cape. Through this study, the factors causing attrition were analysed and presented in such a manner so that change can be conceptualised in order to strive for the rights of children to receive justice for crimes committed against them. Key findings of the study yielded three significant factors which plague the progress of these cases. A significant finding illuminated the lack of required capacity professionals have in working and understanding children throughout the criminal justice process. A further vital finding is the complexities of inter-departmental functioning on implementation level, indicating challenges in collaboration. An integral finding is the measure of time taken to investigate cases of child victims, which the criminal process flow is delayed to its own detriment in aiming for convictions. In general it was found that services to child victims are neglected. Collaborative approaches which are already in place are to be strengthened through capacity building and collaborative knowledge integration in all sectors of professionals. Victim services legislation must include specialized services for the child victim. , Thesis (MSW) -- Faculty of Health Sciences, 2021

- Description: New technological developments in the field of Hybrid Electric Vehicles (HEV’s), vehicle stop-start applications and electrical power utility devices have brought about new demands on the use of energy storage devices such as the Pb-acid battery. These applications require a new understanding and research into the material chemistry of the battery where it has to functionin a Partial State of Capacity Cycling (PSoCC) or High Rate Partial State of Capacity Cycling (HRPSoCC)duty. The Pb-acid battery is well known for its use in the automotive industry where it had worked for decades as a typical Starter, Lighting and Ignition (SLI) power source. However, the conventional Pb-acid battery is not suitable for the new types of vehicle demands and applications. When the Pb-lead acid battery is subjected to PSoCC conditions, very quickly excessive amount of non-conducting PbSO4crystals are formed on the negative plates of the battery that then drastically reduce its useful life in application. Over the years, researchers have shown that the small addition of certain carbon types to the negative plate active material (NAM) during battery manufacturing can reduce the sulfation effect thereby increasing its use the modern vehicle applications. This study investigated industrial manufactured cells that contained up to 0.5 % by weight two types of carbons in the NAM. These were compared to standard built cells in terms of their standard achievable capacities at various rates, their Cold Cranking Ability (CCA), their Dynamic Charge Acceptance (DCA) and a simplified PSoCC test. The carbons were classified as an activated carbon and a carbon nano-fiber and were included as a dry weight additive during the standard paste manufacturing process of the negative plate. Cells were built with a 9-plate configuration using standard expanded grid positive plates with a nominal rated capacity of 36 Ah. The cells were formed and subjected to a number of electrochemical tests, of which selected negative plates were then studied using Scanning Electron Microscopy (SEM) and Electrochemical in-situ Atomic Force Microscopy (EC-AFM). The microscopic study was then used to try and relate the observed material characteristics of the NAM with the carbons to the electrochemical results observed when testing a built cell. , Thesis (MA) --Faculty of Science, School of Biomolecular and Chemical Sciences, 2021

- Description: The focus of this study is the factors that influence recycling behaviours, particularly whether incentives are likely to change consumers’ recycling behaviours in South Africa. Africa is said to become the most polluted continent within a few decades. Three of the largest metropoles in South African are likely to run out of landfill space within the next ten years. Waste streams provide considerable opportunity if waste can be safely collected and either reused, recycled, or recovered, but extracting value from the waste streams is costly and difficult. Consumers need to separate waste at source to improve the efficacy of the recycling stream, yet South Africans do not separate waste at source as a norm. The question that arises then is would an incentive improve South Africans’ willingness to recycle? This study tried to determine if incentives are likely to change consumers’ recycling behaviours in South Africa. It explored the relationship between factors that influence recycling behaviours grounded in Taylor and Todd's (1995) extension of Ajzen's (1991) Theory Of Planned Behaviour. A quantitative survey design, using both online and face to face questionnaires, was used to collect data from a cross section of randomly selected consumers. The research determines that the call to address waste management infrastructure and facilities, is indeed correct. It further confirms previous research findings that an incentive alone is not enough to change recycling behaviours as it will not negate other environmental factors. Lower income groups are more conscientious about recycling and may be enticed to participate in the recycling industry through an incentive to improve their income. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business Administration, 2021

- Description: As an organist and Catholic musician, I have an interest in exploring the role of, as well as attitudes towards, the pipe organ in the liturgy in the Catholic parishes in South Africa. Among both Christian and secular newspapers, headlines paint a picture of a decline in the use of the organ in churches and the number of organists in the world today (The Canadian Press, 2012). By conducting this study, my goal was to better understand this phenomenon in the context of my local diocese of Port Elizabeth. , Thesis (MMus) -- Faculty of Humanities, 2021

- Description: Increased rate of antibiotic resistance (AR) poses a serious threat with a resultant notion of a possible end of the antibiotics era, making it a problem of concern to public health and a great implication on the world economy and human society. Despite many approaches developed to curb this menace, antibiotics resistance is still a challenge worldwide. This has made the use of combined therapy as one of the options in many cases. This study was conducted to assess antibiotics combination therapy as an option for the control of antimicrobial-resistant non-cholera causing Vibrio species that were recovered from the environment in the Eastern Cape, South Africa. Two hundred and twenty-eight Vibrio species were recovered from the environment in the Province, and these were deposited in the archive of AEMREG. PCR was used to identify target Vibrio species. Disc diffusion method was used to evaluate the antibiotic susceptibility profile of the confirmed isolates against 11 antibiotics commonly used against infections. MIC and MBC were determined using antibiotics (imipenem, tetracycline, and nalidixic acid) that high resistance was discovered. Checkerboard assay was used to carry out antibiotics combination assay, and the FICI was calculated. Rate of kill was also determined using ½ × MIC, 1 × MIC, and 2 × MIC concentrations of the combined antibiotics at 2 hr intervals. One hundred of the isolates were confirmed to be Vibrio parahaemolyticus, 82 were Vibrio vulnificus and 46 were Vibrio fluvialis. Twenty-two (22) percent of the Vibrio parahaemolyticus isolates showed resistance against tetracycline and their resistance against other antimicrobials is as follows; nalidixic acid (16 percent), ampicillin (14 percent), cefotaxime (14 percent), chloramphenicol (12 percent) and amikacin (11 percent). For Vibrio vulnificus, prevalence of resistance was as follows: imipenem (40 percent), tetracycline (22 percent), ampicillin (18 percent), meropenem (15 percent), and chloramphenicol (11 percent). Vibrio fluvialis showed the following resistance profile: nalidixic acid (28 percent), tetracycline (28percent), ampicillin (20 percent), chloramphenicol (15 percent), amikacin (11 percent) and cefotaxime (11 percent). About 38 multiple antibiotic resistance phenotypes (MARP) were recorded in all species that were evaluated. About 23 percent were resistant to over 3 antibiotics used. The multiple antibiotic resistant indices (MARI) ranged between 0.3 and 0.8. MIC and MBC were carried against isolates that were resistant to the two most common antibiotics tested. MIC and MBC were determined in the following order: tetracycline and nalidixic acid at concentrations ranging from 16 μg/ml to 1024 μg/ml for Vibrio parahaemolyticus and 32 μg/ml to 2048 μg/ml for Vibrio fluvialis. Also, the MIC and MBC of imipenem and tetracycline at concentrations ranging from 8 μg/ml to 256 μg/ml for Vibrio vulnificus were determined. Antibiotics combination therapy was carried out and synergistic activity was observed in 3 of the 16 resistant V. parahaemolyticus isolates, 3 of the16 resistant V. vulnificus isolates and 2 of the 13 resistant V. fluvialis isolates. Antagonism was not observed across all the drug combinations. Rate of kill was also determined and at 6 hr exposure time, the highest concentration (2 × MIC) exhibited bactericidal effect across all three Vibrio species. The result derived in this research, therefore, propose that combination therapy is a promising solution to antimicrobial resistance in Vibrio species. , Thesis (MSc) -- Faculty of Science and Agriculture, 2021

- Description: Successful employee retention is essential to an organisation’s stability, growth and revenue. Without properly implemented employee retention strategies, the organisation may face high employee turnover rates. An increased longevity of an employee’s tenure is better for the organisation’s overall performance. This study sought to evaluate the factors affecting employee retention at the IDC. To enhance the success of the study, the research objective was to assess the relationship between five HR factors and employee retention within the IDC. The study used a descriptive survey research design. The sampling method used for this study was convenience sampling. A questionnaire was used for data collection. The researcher cleansed and coded the data, whilst a statistician entered the collected data into STATISTICA. The data was analysed descriptively and also by means of inferential analysis method that is. The descriptive data was presented in the format of pie charts and tables with percentages, means and standard deviations as measures for distribution mechanisms. While inferential analysis presented the regression in table formats but with a clear indication of significant levels and adjusted R-square for all the independent variables. The sample that participated in this study consisted of 288 respondents from the IDC. Empirical findings revealed that the working environment, work-life balance, compensation and employee engagement positively influenced employee retention. Career development was not significantly related to employee retention. The study concluded and made recommendations to four stakeholders, namely the government to have roadshows and marketing activities to promote the Skills Development Act and skills Levies Act, IDC to review their employee retention strategy, Managers or Supervisors to support their employees by providing market related salary packages and provide session where they engage the employees in the organisations developments, and the HR Practitioners must ensure that the right fit of candidates are recruited to the organisation. , Thesis (MBA) -- Faculty of Business and Economic Sciences , Business Administration, 2021

- Description: It is documented that obesity is highly prevalent across rural and urban groups in industrialised and underdeveloped countries. This problem is an alarming issue as community members remain unsure about avoiding risking their health. Various health surveys reveal that obesity has increased among communities in the Buffalo City Metro Municipality in the Eastern Cape, and it has consequently made communities vulnerable to non-communicable diseases. The researcher explored factors and barriers of exercise for rural and urban obese populations in Buffalo City Metropolitan Municipality, Eastern Cape. This study was descriptive and explorative, utilising a questionnaire for gathering information. A purposive sample of 80 members from the two selected communities completed the questionnaire. A factor analysis was performed to identify factors that motivate physical activity and barriers to physical activity. It was discovered that all evaluated members were fully aware of the harmful repercussions of being overweight or obese. Nevertheless, only a tiny percentage of those who took part in the study decided to live a healthier lifestyle because of their obesity. Constructive motivating factors included increasing their self-image, enhancing their wellbeing, and getting highly involved in active and regular exercise. Negative motivators included finding it challenging to fit into old clothes and the worry of developing obesity-related diseases. Respondents noted the following impediments in regular exercises and physical activities; African cultural values, limited operational hours of physical activity facilities, insufficient time, and a lack of enthusiasm. , Thesis (MPhil) -- Faculty of Science and Agriculture, 2021

- Description: Competitive shooting has become immensely popular since the first modern Games held in 1896. Competitive shooting remains the fastest growing segment in the firearm industry, catering to individuals of all ages. Elite shooters are capable of reaching extreme levels of precision and accuracy, despite many factors existing that affect performance in Olympic shooting. One such factor is speed variability, which is dependent on the mass of the bullet, how constant is the lead being used, and, how constant the gunpowder is. The study focusses on the Bayesian simulation method proposed by Wolfinger (1998) for determining three kinds of tolerance intervals when applied to competitive shooting data, particularly examining speed variability. These tolerance intervals included the (𝛼𝛼,𝛿𝛿) tolerance interval (where 𝛼𝛼 is the content and 𝛿𝛿 is the confidence), the 𝛼𝛼 - expectation tolerance interval (where 𝛼𝛼 is the expected coverage of the interval) and the fixed-in advance tolerance interval in which the interval is held fixed and the proportion of process measurements it contains, is estimated. Speed measurements of individual shots fired were measured with either an Oeler 35P or Magneto Speed V3 chronograph and the data was fitted to a one-way random effects model. , Thesis (MSc) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2021

- Description: Bongani Ndodana-Breen is a South African born Xhosa composer trained in Western Classical music and composition. His music is a reflection of his Xhosa heritage, and is internationally recognised. While there have been discussions of Ndodana-Breen’s individual works, the current available literature does not sufficiently investigate his compositional style. This treatise aims to address this. To determine Ndodana-Breen’s compositional style, the techniques and practices he uses in his works are investigated. This is achieved by deconstructing the compositional elements, and musical techniques and practices he employs in his compositions. They are then investigated through the use of thematic analysis and fragmentation, and are viewed through the lens of polystylism and postcolonialism. Ndodana-Breen’s composition Rituals for Forgotten Faces is used as a case study. The results of this investigation show that Ndodana-Breen, through the use of strong rhythms, light textures and simplicity in writing, creates a unique Africanness in his compositions. This Africanness overcomes the Eurocentric sound traditionally found in Western Classical composition. Furthermore, these findings suggest a hybridity of polystylistic elements found in Ndodana-Breen’s music, that could potentially be found in the works of other African musicians that are trained in Western Classical composition. On this basis, this study paves the way for further study of African composers and their works. , Thesis (MMus) -- Faculty of Humanities, 2021

- Description: Background: Globally, childhood mortality remains high with 5.3 million deaths occurring in children under the age of five years in 2018. Of these deaths, 43 000 were children from South Africa, with malnutrition being a significant risk factor contributing to disease and death. Breastfeeding has many benefits and reduces childhood mortality. Current primary health care strategies in South Africa are not having an adequate impact on breastfeeding rates, therefore appropriate messages need to be targeted at the community in order to improve breastfeeding rates. Participatory approaches have been identified as an effective tool to promote child health. Community dialogues led by skilled Early Childhood Development (ECD) mentors from the community might be key in order to improve caregivers’ knowledge, attitudes and practices (KAP) in relation to breastfeeding and Prevention of Mother to Child Transmission of HIV (PMTCT). Aim : The aim of the study was to explore the potential effects of community dialogues, led by ECD mentors, on caregivers’ knowledge, attitudes and practices (KAP) in relation to breastfeeding and prevention of mother-to-child transmission of HIV (PMTCT). Methods: Quasi-experimental design was used to compare the KAP of caregivers in relation to breastfeeding and PMTCT. Convenience sampling was used to include 63 caregivers who participated in the umbrella project (mixed-methods) and 61 caregivers who did not participate in the project. Ethics approval was obtained from the Nelson Mandela University Faculty Postgraduate Studies Committee. Participants had to provide written informed consent. A skilled interviewer used a structured questionnaire to assess the KAP of all participants. Data were captured on an Excel spreadsheet and analysed in collaboration with a statistician, who analysed the data using Microsoft Excel. Descriptive statistics were applied to numerical data, while frequency distributions were applied to categorical data. Correlations were calculated to describe the degree of relationship between two variables. Inferential statistic tests, conducted at a significance level of 0,05, were used for hypothesis testing. The t-test and analysis of variance (ANOVA) were used in tests involving mean values. Scheffé’s test was used in ANOVA to determine between which of the groups a statistically significant difference was found. Results: In the intervention group more than double the number participants (35%; n=22) had a good knowledge of breastfeeding when compared to participants (15%; n=9) in the control group. Additionally, the intervention group participants displayed better attitudes towards the RtHB (p=0.02). However, control group participants showed better knowledge towards the HIV (p=0.01). Finally, results suggest that in the intervention group, participants (33%; n=21) were more likely to have a good total KAP score in relation to breastfeeding and PMTCT when compared to participants (11%; n=7) in the control group. In the intervention group, better knowledge correlated with good practices relating to the RtHB (r=0.27). However, in the control group, positive attitudes correlated with better practices relating to HIV (r=0.29). Younger intervention group participants displayed better breastfeeding related practices (p=0.011). Additionally, younger control group participants displayed better knowledge of breastfeeding (p=0.001). Intervention group participants whose choices were influenced by their husband/ partner (p =0.016) and/ or radio/ magazines/ newspapers (p=0.004) had positive attitudes towards HIV. Control group participants whose choices were influenced by their other family members (p=0.043) and/ or clinic staff (p=0.016) had good knowledge of sharing their knowledge. Conclusions and recommendations: The intervention group displayed a better knowledge of breastfeeding as well as more desirable attitudes towards the RtHB, when compared to the control group. However, the control group displayed better knowledge of HIV, which could be due to the control group having more younger participants when compared to the intervention group. The community dialogue intervention had a positive impact on caregivers KAP relating to breastfeeding and PMTCT, which included all the different categories combined. In order to improve the Sakha Esethu intervention programme, managers need to provide guidance to the mentors on how to initiate conversations regarding HIV and discuss the stigma associated with HIV and breastfeeding. Results showed that including grandmothers and husbands or partners in the target population will benefit the intervention. Additionally, the use of radio needs to be considered especially for discussions regarding HIV. Lastly, sustainability needs to be improved due to many participants not remembering certain detail regarding topics that was discussed. , Thesis (MSc) -- Faculty of Health Sciences, 2021

- Description: As part of the legacy of colonialism, colourism, or intra-racial discrimination, is a complex phenomenon in India and in the Indian diaspora. To explore the nature of such intra-racial hierarchies, this research contextualises the historical frameworks of British colonial rule in India, the Indian indentured labour system in South Africa, and racial segregation during the Apartheid regime. Significantly, the legacies of these systems of oppression work on two distinct yet intertwined levels: race and colour. Because the colour of one’s skin can greatly influence education opportunities, socio-economic mobility, and general well-being in communities of colour, the problematic relationship between skin complexion and access to resources can encourage a yearning for whiteness or lightness. Aided by Eurocentric standards of beauty and ethnic marketing, the media plays a key role in exacerbating the issue of colourism and fortifying a multi-million dollar skin-lightening industry. From the vilification of darker-skinned actors in Bollywood to beauty products with potentially-harmful ingredients being promoted as the main, or only, means to success, the media and skin-lightening industry exploit the desire for a lighter skin tone to sell a lifestyle underpinned by white aesthetics. Thus, this research analyses the power of the media in championing colourist ideals as well as how the media can be used to dismantle such ideals. While there exists an extensive amount of academic literature on colourism, previous work has failed to address the ways in which colourism is present within the South African Indian diaspora. Arguably, Indian people have a unique history of being both oppressed and privileged in South Africa and it is in this in-between space where colourism thrives. Thus, through the use of an audience study and, consequently, data collection and analysis, this research explores the personal experiences of colourism-based discrimination and privileges in the South African Indian diaspora. While this research does not aim to provide conclusive answers and/or solutions to the issue of colourism, it is paramount to include an audience study as the World Health Organisation (WHO) has reported that 35% of South Africans participate in skin-lightening processes. Thus, this research aims to provide insights into the ways in which South African Indians engage with colourism and the extent to which they participate in skin-lightening practices. The findings of this research aim to illustrate that colourism remains rife in the South African Indian community as it is often ‘passed down’ from generation to generation. Moreover, the analysis of the participants’ responses demonstrates that, despite the fragile nature of determining one’s worth based on skin tone, colourism can have a long-term impact on the mental, emotional and physical health of South African Indians. , Thesis (MA) -- Faculty of Humanities, 2021
