- Description: COVID-19 increased in prevalence in 2019 and was declared a pandemic in 2020 by the World Health Organisation (WHO). The pandemic arrived in South Africa in March 2020, and drastically impacted the country. One such impact was to healthcare workers, who had contact with COVID-19 patients on an ongoing basis. Increasing pressure was placed on healthcare workers, and they needed to cope with the demands placed on them during the pandemic. The study aimed to explore and describe the coping experiences of healthcare workers during the COVID-19 pandemic in the Nelson Mandela Bay Health District. To meet this aim, a qualitative explorative descriptive research design was used. Data was collected using individual, semi-structured interviews, with a sample of 10 healthcare workers in the Nelson Mandela Bay Health District. The data was analysed using Braun and Clarke’s (2006) Reflexive Thematic Analysis and the trustworthiness of the study was ensured through Guba’s (1985) model of data verification. Social Constructionism was used as a theoretical framework to conceptualise the findings that emerged from the participants within their socio-historical context. Participants shared their coping experiences which were different from the other but shared particular themes. Participants made use a combination of problem, emotion and meaning focused coping strategies during the peaks while utilising predominantly problem focused coping strategies during the lulls. It became apparent that there were differences in coping in terms of the lulls and the peaks with peaks producing fear and anxiety, while lulls bringing a sense of relief. , Thesis (Ma) -- Faculty of Health Science, 2023

- Description: The mixed methods action research study explored how collaborative writing and scaffolding practices impacted on the writing performance of students writing in groups. It sought to establish whether using the collaborative writing (CW) method would enhance the writing performance of 55 social work Midlands State University first-year students. Socio-cultural theory (SCT) was employed as the theoretical basis for the study as it emphasises learning in socially constructed environments in which interaction among peers and teachers leads to learning and construction of knowledge. Through the examination of student interactions in two collaborative writing activities, an analysis of student perceptions of CW, and an assessment of student collaboratively produced texts, the study found that the different peer and teacher scaffolding practices that were employed in the collaborative writing sessions significantly enhanced the students’ writing performance. Regardless of the challenges identified in CW, for example, misunderstandings and meaningless contributions from some group members, the research findings revealed that the student interactions offered scaffolding to support their writing activities. For example, validation feedback, link to previous knowledge and the use of correctional feedback were the scaffolding practices used. In addition, the students were able to collaboratively produce better texts with improved cohesive linking, mechanics, organisation, development, structure and vocabulary. The study contributed to L2 collaborative writing literature as it identifies the different student scaffolding approaches and offers an insight into the collaborative writing process and how it could support ESL writing development. However, the methodology posed some limitations, for example, the use of a questionnaire instead of interviews and recording student interactions in a journal instead of audio recording and, lastly, the researcher struggled to balance research demands and her normal teaching load. The study recommends the monitoring of students in CW groups, facilitation of peer/teacher motivation, establishment of group norms and formation of small groups with a maximum number of six members. , Thesis (MA) -- Faculty of Humanities, 2023

- Description: Exploring gender identity and ideology can broaden our comprehension of how gender roles and responsibilities are carried out, and how disparities may be experienced. It is critical to explore them, within research, to generate new insight into the views and positioning of individuals, within their intimate relationships. Therefore, the aim of this study was to explore and describe the perceptions of isiXhosa men about their roles and responsibilities in intimate relationships. The study was broken down into three objectives which were: to explore perceptions of their role within their relationship, to explore their perceptions of their responsibilities within their relationship; and to explore factors supporting change within the roles and responsibilities. The study took the format of an exploratory descriptive research design. Ten Xhosa men were selected as participants using snowball sampling, and semi-structured interviews were used to gather data. Data was analysed using Braune and Clarke’s (2006) reflexive thematic analysis. The study came to the conclusion that there are two main roles of Xhosa men in intimate relationship, namely: head of the house; and the provider. Three dominant responsibilities were found to be common among the participants, namely, making all main decisions, providing financial support, and responsibility to safeguard. The study also found factors causing Xhosa men to change their roles and responsibilities in intimate relationsh were unemployment, disrespectful partner, extended family needs, demanding job and inadequate income from work. Lastly, the study concluded that the extent to which the changes of the roles and responsibilities among Xhosa men may affect their intimate relationships include break-ups/divorce, domestic violence, dysfunctional families – fragmentation of families and mental and emotional health issues. , Thesis (Ma) -- Faculty of Health Science, 2023

- Description: The role of Traditional Birth Attendants (TBAs) has been within remote communities for a long time. TBAs remain a major health resource in rural communities in developing countries as well as in some parts of urban areas. South Africa is a long way from effectively utilising TBAs as a community resource to enhance access to maternity services. This qualitative study, with an explorative, contextual, and descriptive design, included ten (n=12) TBAs aged between 38 and 56 years who met the inclusion criteria and were interviewed for the study. The objective of the study was to explore and describe TBAs’ perceptions of their role in caring for women during childbirth in the Nyandeni Sub-district. Data for this study was collected using face-to- face and individual semi-structured interviews, and field notes. Recorded data was transcribed verbatim and analysed using thematic analysis. Three main themes emerged, namely: TBAs perceive their role in caring for women as an essential service to women in the community; they believe that they possess the knowledge to conduct deliveries safely; and acknowledge that collaboration with the Department of Health could strengthen rural midwifery services. , Thesis (Ma) -- Faculty of Health Science, 2023

- Description: Medication adherence is a patient's active and voluntary participation in following all the recommendations and instructions agreed upon with a health care provider such as a pharmacist. Adherence is a multidimensional phenomenon determined by the interplay of five factors: patient-related factors, socioeconomic factors, condition-related factors, health system-related factors, and therapy-related factors. Medication non-adherence is a problem in many countries, especially low to middle-income countries, including South Africa (SA). In low to middle-income countries, non-adherence is often worse due to insufficient health resources and inequities in access to health care. Medication adherence is a global problem and has raised the need for research and review. Many healthcare professionals, especially pharmacists, have an essential role in promoting medication adherence. This study described, explained and evaluated the policies in SA relating to the pharmacist's role in promoting medication adherence. Furthermore, it described medication adherence-related education at four universities in South Africa. The study was qualitative, and a two-phased approach was employed. In the first phase, a document analysis of the pharmacist’s role in supporting medication adherence was conducted as described in national policies and guidelines in SA. A total of 38 documents were analysed, including critical documents such as the South African Pharmacy Council Good Pharmacy Practice Manual and Associated SAPC rules (GPP) manual, National Drug Policy (NDP), Standard treatment guidelines (STGS) and Integrated Adherence Guidelines. The READ approach was used in conducting the document analysis and involved (1) preparing materials, (2) extracting data, (3) analysing data, and (4) distilling findings. The critical roles of pharmacists in medication adherence that were identified were in drug use, supply and management, dispensing, therapeutic drug monitoring, pharmacovigilance, pharmaceutical care, and special programmes like antimicrobial stewardship (AMS), multi-drug resistant tuberculosis (MDR-TB) care and antiretroviral treatment (ARV) and chronic conditions. In the second phase, in-depth interviews were conducted with lecturers to investigate and report on the inclusion of medication adherence and the teaching thereof in the curriculum of the Bachelor of Pharmacy Degree (BPharm) in pharmacy institutions in SA. Purposive sampling was used, and seven lecturers from four different institutions participated in the interviews. The interviews were conducted via Zoom® and were transcribed and analysed using thematic analysis. The teaching of medication adherence in the BPharm curriculum of the respective interviewed pharmacy institutions was explored. It was found that the topic of medication adherence was integrated into all subjects throughout the curriculum and not taught as a formal course. Although medication adherence is taught in many disciplines, it is predominantly in pharmacy practice in all institutions. The teaching methods identified included lectures, case studies, workshops, tutorials, practicals, readings, tasks, assignments and videos. The perceived effectiveness of the teaching methods was explored; also the time spent teaching medication adherence and the time efficiency. Student understanding, interest and engagement with the topic were explored and determined through their assessment performance and class attendance. In conclusion, from policies, the pharmacist's role concerning adherence is indirectly integrated into many other roles. It is often not distinguishable from that of other healthcare professionals and is often implied as part of a more generic role. Pharmacy students are educated on medication adherence and the skills and knowledge required to identify, monitor and support patient adherence to therapy. However, there is scope to increase the course content on medication adherence. There is a need to identify effective strategies for preparing pharmacists to assist patients in medication adherence. , Thesis (MPharm) -- Faculty of Pharmacy, 2023

- Description: This research investigation is based on continuous improvement changes arising from - and related to - ISO 9001 implementation at Sundays River Citrus Company (SRCC), which is one of the biggest packers, marketers, and exporters of citrus fruit in South Africa. The Board of SRCC adopted ISO 9001 to ensure organizational efficiency and sustainability while improving quality control, customer service, teamwork and leadership. However, research indicates not all organizations that have Implemented ISO 9001 realize the intended benefits. While no research was available on the citrus agriculture industry, research in the tourism industry indicates that not only did some companies not realize the expected benefits, but also incurred substantial investment costs. It is estimated that approximately thirty to ninety percent of change initiatives fail to meet their objectives, and research studies also indicate that middle managers play a critical role that can influence the outcomes of a change project. However, Balogun (2003) indicates that middle managers play a complex role and are exposed to role conflict, which can influence the outcomes of change initiatives. In this context, this research study aimed to investigate the role conflicts experienced by middle managers during the process of an ISO 9001 continuous improvement change. The study draws on role theory, applying it to their management of change. The following role conflict types were investigated: (1) intra-sender conflict, (2) inter-sender role conflict, (3) inter-role conflict, (4) role ambiguity and (5) role strain. The research approach is qualitative, and has adopted a post-positivist paradigm, utilizing a deductive qualitative method. The study adopted a case study approach. Data was gathered mainly from interviews and supported by organizational documents. Semi structured interviews were conducted with questions formulated through the use of the coding manual (See Appendix C) to ensure alignment of data collection with the research propositions derived from literature. A deductive thematic analysis method was used to analyze the interview data. The research findings confirmed that during continuous improvement change, as middle managers strived to satisfy the incompatible expectations of role senders (mainly senior and junior managers), they experienced the five role conflict types. The study findings also indicate that middle managers experience conflicts due to the incompatible expectations of other role senders such as quality and marketing departments. The findings suggest that middle managers are managing these conflicts, but notes that they do require some assistance and support from senior management. The study concludes with managerial and research recommendations. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2023

- Description: This thesis comprises extracts of life writing written in short prose forms. The work reads like a novella and I have been inspired by Margaret Patton Chapman’s approach to the novella, where she condenses “the telling of a long story time wise”, so that a story occurring over two years can be told over two pages. The thesis explores relationships between mother, daughter, grandmother and granddaughter, each with different life experiences and each teaching the next generation about how to navigate life as politically, socially and economically disadvantaged women. I have also drawn inspiration from authors such as NoViolet Bulawayo who explores the hypocrisies of the church and the government in We Need New Names. In Kate Bernheimer’s “Fairy Tale is Form, Form is Fairy Tale” she writes about fairy tales adopting “intuitive logic” or telling in the form of “this happens and then this happens” while the explanation behind the events is not spelt out but rather exists between the lines. My thesis adopts this style of writing by allowing the reader to understand what is being said without over-simplifying. To this end, I have used the concept of place modelled on Es’kia Mphahlele’s In Corner B, where characters are inscribed in relation to the spaces they inhabit. , Thesis (MA) -- Faculty of Humanities, School of Languages and Literatures, 2023

- Description: The Head of Department (HOD) position at a university has traditionally been viewed as an individual construct. However, due to the demanding nature of such a position, it is not sought-after, as it remains exclusive and unappealing to many academics. Moreover, it is a position that does not encourage inclusive leadership. Tension and role ambiguity are known to arise between the scholarly project on the one hand and management and administrative matters on the other. To address challenges associated with this singular leadership position, an academic department at a South African university adopted a distributed leadership approach in their department as a research experiment. My study was based on this research experiment. I designed this research as an exploratory case study, guided by a socio-cultural conceptualisation of distributed leadership that included a leader-plus and a practice aspect, defined as a product of the interactions of school leaders, followers and their situation. This qualitative case study aimed to describe and explain how a distributed leadership approach was understood and practised in an academic department. It also investigated the enablements and constraints of the approach. Data were generated through document analysis, observation, and individual and focus group interviews. The participants in this study included the departmental leadership team and the department’s academic and administrative staff. Unfortunately, my study took place during the global COVID-19 pandemic and national lockdowns. I had no choice but to adapt my data generation methods due to lockdown restrictions. As a result, most data generation was done via online communication. The study used inductive and abductive analysis to make the data meaningful to the reader. The findings revealed that different participants had different ideas about distributed leadership. Distributed leadership was understood as a socio-cultural practice rather than an individual practice with multiple leaders in relational practice. In addition, this approach was understood as a way of developing and sharing expertise by encouraging teamwork, collegiality and collective decision-making which aligns with the notion of democratic decision-making which creates a platform for the enablement of leadership in others. The study further explored how distributed leadership was practised. The findings were that the HOD position, usually a one-person role, was reconceptualised as a HOD team comprised of three academics and the departmental administrator. The HOD team divided the work among themselves, and this was done according to each individual’s expertise. In addition, leadership within the academic department was not limited to the HOD team but stretched across the department; thus, multiple leaders were evident. Therefore, based on the data, this study discovered that a distributed approach values leadership expertise in others. Consequently, it can be used to promote an inclusive environment in which any organisation member can lead. Inclusivity in the decision-making process was also regarded as a strong practice in the academic department. As a result, this study contends that those in formal positions can develop leadership in others through a distributed leadership approach. Through that, lecturer leadership was enacted through formal faculty and university structures and informally as and when the situation required it. The enablements of this departmental leadership approach included the structural innovation of the Friday check-in as well as the buddy system. These two innovations provided the space for collegiality and the development of voice and leadership. The consultative nature of the HOD team was also viewed as an enablement. Certain factors constrained the distributed leadership approach, one of which was the tension between the hierarchical structure of the university and the more horizontal, distributed leadership approach being piloted in the academic department. In addition to that, another constraint was also very real with the transition to Zoom as an online teaching, learning and supervision platform as a consequence of the COVID-19 pandemic. The final constraint was experienced concerning the department’s history, as it was within a historically White university in South Africa. The effects of this history impacted the departmental culture and, as we know from the literature, institutional culture is extremely difficult to change. Finally, the study concluded that conceptualising distributed leadership as a sociocultural practice with leader-plus and practice aspects provides descriptive language and a solid theoretical and analytical framework for a distributed leadership study. The study makes an important knowledge contribution in the African Higher Education context as limited research has been carried out in this area. Furthermore, in terms of practice, my study serves as a stimulus for leadership discussions that are beneficial to everyone involved in educational institutions as they promote a level of leadership reflexivity, currently absent in many institutions. , Thesis (MEd) -- Faculty of Education, Secondary and Post-School Education, 2023

- Description: The Head of Department (HOD) position at a university has traditionally been viewed as an individual construct. However, due to the demanding nature of such a position, it is not sought-after, as it remains exclusive and unappealing to many academics. Moreover, it is a position that does not encourage inclusive leadership. Tension and role ambiguity are known to arise between the scholarly project on the one hand and management and administrative matters on the other. To address challenges associated with this singular leadership position, an academic department at a South African university adopted a distributed leadership approach in their department as a research experiment. My study was based on this research experiment. I designed this research as an exploratory case study, guided by a socio-cultural conceptualisation of distributed leadership that included a leader-plus and a practice aspect, defined as a product of the interactions of school leaders, followers and their situation. This qualitative case study aimed to describe and explain how a distributed leadership approach was understood and practised in an academic department. It also investigated the enablements and constraints of the approach. Data were generated through document analysis, observation, and individual and focus group interviews. The participants in this study included the departmental leadership team and the department’s academic and administrative staff.

- Description: This thesis is a secondary component to an artistic practice-led process and as such, is guided by my own artistic practice in that way. In this body of work, I use myself as the main character or protagonist for the artworks that I have created. However, both the thesis and the exhibition also respond to social issues of identity beyond the personal and examines the construction of identity in a South African, and more specifically Makhanda context, as that is the larger context in which I am situated. The work itself is inspired by memories and experiences of feeling uncomfortable in my own (first) skin, and how I found that comfort in my second skin (dress). My professional art practice and my thesis are based on the concept of clothes as a second skin for human beings, specifically observing the ways in which we utilise dress to construct and express our identities. As such, this thesis is an attempt at understanding the relationship between clothes and the body through the lens of identity politics. Through the topics and artworks discussed in visual and textual analysis, this thesis intends to unpack the properties of dress as a complex medium individuals can utilise as a tool to construct their identity. This is partially achieved through the exploration of my own personal experiences of dress and of the spaces that shaped and mediated the construction of identity. Lastly, it is an attempt to understand the experiences of dress in parallel to the experience of the body/self, which consists of the world within and the one outside. , Thesis (MFA) -- Faculty of Humanities, Fine Art, 2023

- Description: Background and Purpose. The South African citrus industry is a major global producer of citrus as well as the second largest exporter of citrus fruit in the world. This industry provides employment to an estimated 112 000 workers in South Africa and is vital in providing economic opportunities to communities such as those in the Sunday’s River Valley in the Eastern Cape province of South Africa due to the low employment and education levels within this province. Citrus sorting is a visual inspection task that requires workers to sustain attention and remain vigilant for the duration of a working shift. Their role in the packhouse is to ensure that no defective products are packed for export or the local market and that the fruit meets the customers’ expectations. Since the demands of sorting citrus are poorly understood, this study attempted to assess the effect that sorting citrus has on vigilance performance as well as attempt to quantify perceived workload while taking into account different contextual factors that affect perceptions of this working task. Methods. This study was conducted within a citrus packhouse in the Eastern Cape province of South Africa. The sample was comprised of individuals employed by the packhouse as citrus sorters. In addition to a recruitment and information session, testing was conducted at three intervals during a working shift on four consecutive days. Each time, indicators of vigilance, such as correct responses, sensitivity, reaction time, false alarms and misses, were collected during a 5-minute computerised version of the Mackworth Clock-test, while perceived workload was assessed with the NASA-TLX scale, and sleepiness was recording using the WITS Sleepiness Scale. Furthermore, an open-ended question was asked to further understand factors affecting the ability of participants to concentrate during their task of sorting. Results. 18 participants consented to participate in this study. 16 of these individuals identified as female with an average age of 30 years (± 7). 83% of participants were of Black African descent and were isiXhosa speakers, while 17% of participants were of Coloured descent and Afrikaans speakers. This study found that performance, as measured by the percentage of correct responses, sensitivity and reaction time on the 5-minute long Mackworth Clock Test was not significantly affected as time-on-task for sorting citrus increased during a working shift, neither did performance on the vigilance test change as days of the week proceeded. However, ‘misses’ during the vigilance test were found to significantly decrease over the course of a working shift, thus contradicting the expected outcomes of this study. Perceived workload of sorting citrus, as well as perceived sleepiness, significantly increased with time-on-task during the course of a working shift. The major contributions for this increase in perceived workload while sorting citrus were derived from the Mental Demand and Physical Demand sub-scale for the NASA-TLX. However, responses from the open-ended question indicated that participants generally enjoyed their work, although there were factors, such as the nature of fruit and social set-up of work, that negatively affected this perception. Discussion. The results from this study contradicted the researcher’s expectations. It was anticipated that measures of correct responses and sensitivity would decrease and misses, and reaction time would increase with time-on-task for sorting citrus, yet vigilance indicators from the Mackworth Clock Test generally indicated no change in vigilance, and, according to “misses” even improved with time-on-task. A likely explanation for this is that the use of a 5-minute Mackworth Clock-test was unsuitable in this context, or rather, the time of this test was not long enough to induce a ‘vigilance decrement’. Furthermore, in order to administer this vigilance test, participants were taken off the production line and led to a testing room which most likely increased their levels of arousal, thus affecting performance on the vigilance test. However, even though perceived sleepiness was found to significantly increase over the course of a working shift, these data correlated poorly with the vigilance results, thus contradicting the expected outcomes of the study. Mental demand significantly increased, possibly due to the demand of attentional informational processing required for sorting, as well as various environmental factors present within the packhouse. Physical demand, too, significantly increased as workers were required to remain standing throughout their working task as well as to make use of their upper extremities to remove defective fruit. Correlation analyses showed significantly weak correlation for Mackworth Clock Test variables and sleepiness ratings to all other variables. NASA-TLX variables, however, generally showed significantly moderate correlations with one another. Conclusion. It remains unclear how vigilance changes and sustained attention while sorting citrus, since the experiment did not show changes in performance. This is largely attributed to the methodological set-up which could have increased arousal and therefore affected vigilance. It is recommended that future studies research vigilance and sustained attention during the sorting itself, rather than attempting to infer vigilance results from a computerised vigilance test. Perceived workload of sorting, however, increased over the course of a working shift due to significant increases in perceptions of the physical and mental demands of sorting. Future studies should address concerns relating to the physical demand of sorting. Furthermore, it would be beneficial to compare responses of day and night shift sorters to further understand how the relationship between these variables may change. , Thesis (MSc) -- Faculty of Science, Human Kinetics and Ergonomics, 2023

- Description: Today’s teaching space is more diverse than before. As a result, differentiated instruction is considered helpful in supporting learner diversity. This teaching approach considers socio-cultural, multiple intelligences, and learning styles also termed learning preferences of learners. It is against this view that I wanted to investigate the implementation of differentiated instruction teaching practices in the Foundation Phase. This study explored differentiated teaching strategies and procedures in mathematics teaching, and I observed four Grade 3 teachers. The theoretical framework underlying this study was the theory of practice architectures. This study is located within an interpretivist paradigm within which I employed a case study research design. The collection of the data sets was through observations and semi-structured interviews. For an analysis of observations, I used a deductive approach. On the other hand, for the semi-structured interviews, I use an inductive approach to discover patterns and themes that I applied during the data analysis process. The validation process was done by giving interview transcripts and a summary of discussions to respondents to verify their responses and check for any misinterpretations. Rich data sets were analysed concerning the research questions, which were as follows: What are the current differentiated instruction teaching practices used by Grade 3 Mathematics teachers? How can the teachers’ differentiated instruction teaching practices be understood in terms of doings, sayings and relatings? How are differentiated instruction teaching practices made visible through the lens of the Theory of Practice Architecture? The findings from the study revealed that the use of learners’ everyday language influences their understanding of mathematics terminology. The study discovered that learners were more comfortable using English to make sense of mathematics terms instead of using isiXhosa, the Language of Learning and Teaching in the Foundation Phase. Additionally, linking learning to learners’ everyday English language enabled them to learn mathematics terms in a relaxed and non-threatening situation, while isiXhosa seemed to constrain learning. Further, the findings revealed that teachers were unclear about differentiated instruction. That was evident when they did not know the elements of differentiated instruction. Thus, the study recommends that teachers need to be supported through workshops to enable them to enact differentiated instruction in their teaching. , Thesis (MEd) -- Faculty of Education, Secondary and Post-School Education, 2023

- Description: In 2020, South Africa faced a significant challenge as it grappled with approximately 500,000 COVID-19 infections, which accounted for over half of all reported cases across Africa. Living through a global pandemic such as COVID-19 had a dramatic and transformative impact on the arena of death for many South Africans, not only because of the number of deaths that have occurred globally due to COVID-19, but also how the bereaved living honour the dead. This study delves into a previously underreported facet of the pandemic's impact, focusing on the experiences of bereaved AmaZulu people who encountered profound disruptions in funerary rituals due to COVID-19 restrictions. The research aims to shed light on how spirituality may mitigate the challenges posed by these ritual constraints, drawing parallels with other ethnographies which have highlighted the importance of spirituality among the AmaZulu people of the Midlands in KwaZulu-Natal, South Africa. This study employed a mixed method approach in generating quantitative and qualitative data. Data from 101 participants who responded to an online questionnaire were analysed using STATA. Additionally, ethnographic data with 9 participants, purposively sampled from the larger sample, was analysed using an Interpretive Phenomenological Analysis (IPA) approach, which ensured that their lived experiences of bereavement took centre stage. The findings of this study illuminate the regret experienced by participants who adapted to [government] bureaucratically-imposed funerals and medical care, revealing potential implications for future pandemic responses. This research underscores the significance of customary funerary rituals, urging compassionate public health responses that acknowledge their role amid mass deaths. It also highlights the interplay between spirituality, religion, and rituals, showcasing how these elements form an intricate web in the AmaZulu community. This study contributes to the broader understanding of death and COVID-19 in South Africa, where racial disparities in COVID-19 deaths have come to the forefront. It addresses the enduring trauma within Black communities and explores how the absence of funerary rituals can strain the psychological, emotional, and spiritual fabric of the bereaved. , Thesis (MSocSci) -- Faculty of Humanities, Athropology, 2023

Additionally, ethnographic data with 9 participants, purposively sampled from the larger sample, was analysed using an Interpretive Phenomenological Analysis (IPA) approach, which ensured that their lived experiences of bereavement took centre stage. The findings of this study illuminate the regret experienced by participants who adapted to [government] bureaucratically-imposed funerals and medical care, revealing potential implications for future pandemic responses. This research underscores the significance of customary funerary rituals, urging compassionate public health responses that acknowledge their role amid mass deaths. It also highlights the interplay between spirituality, religion, and rituals, showcasing how these elements form an intricate web in the AmaZulu community. This study contributes to the broader understanding of death and COVID-19 in South Africa, where racial disparities in COVID-19 deaths have come to the forefront. It addresses the enduring trauma within Black communities and explores how the absence of funerary rituals can strain the psychological, emotional, and spiritual fabric of the bereaved. , Thesis (MSocSci) -- Faculty of Humanities, Athropology, 2023

- Description: Background: South Africa is the second most influential exporter of citrus fruits internationally and holds a pivotal role in economic revenue for the country. Rural areas, such as the Sundays River Valley in the Eastern Cape province of South Africa, contribute to the country’s citrus production. Many women depend on citrus packhouses for employment as citrus sorters. As humans perceive certain defects in citrus fruits more accurately than machines, these sorters must identify and manually remove any fruit that does not conform with export requirements. Citrus sorters are exposed to numerous physical and cognitive stressors during the task while faced with organizational challenges, such as shift work and long working hours. Therefore, the potential for fatigue development is anticipated. Given the multifactorial nature of fatigue and the negative consequences it may have on workers, it also has the potential to impede the accuracy of the sorting performance. Stringent disciplinary action for the entire South African citrus industry may be of consequence if nonconforming or pest-infested fruit is missed by citrus sorters and exported to foreign countries. This study aimed to investigate the prevalence of fatigue among citrus sorters in a citrus packhouse in the Sundays River Valley of the Eastern Cape throughout a citrus harvesting season and to identify factors that may contribute towards fatigue development. Methods: The research design utilized a crosssectional, two-part approach that applied mixed methods. Part one was administered once-off, incorporating demographic, work-, and non-work-related questions. Part two was a self-developed repeated measures assessment comprising close-ended contextual questions, the Modified Fatigue Impact Scale, and the Karolinska Sleepiness Scale. Environmental and work output data were also recorded. Results: Citrus sorters (n= 35) recorded a mean MFIS score of 39.35 throughout the harvest season, which was above the prescribed fatigue threshold (38). However, there was no significant difference in fatigue ratings over time (p= 0.122). Day shift workers exceeded the fatigue threshold for the entire season compared to night shift workers, who only exceeded it in the last two weeks. The physical, cognitive, and psychosocial subscales found no significant difference in fatigue scores, although physical fatigue recorded the highest scores across all weeks and displayed a significant difference over time. Overall, participants, on average, perceived to be “neither sleepy nor alert” over the season. However, eight participants (22%) recorded sleepiness scores ii exceeding the excessive sleepiness threshold of seven. Educational levels, health status, work-pace, and the number of family dependents significantly contributed to fatigue development, albeit a weak correlation. Discussion: Sorters were perceived to be fatigued from week three till the end of the study; however, there was no variation in fatigue scores over time. An accumulation of physical fatigue over time was revealed where prolonged standing, repetitive work, and irregular working postures may have contributed. Night shift workers did not receive the recommended hours of sleep (7-8 hours); hence, they registered greater sleepiness scores over the season than day shift workers. Environmental and work output recordings did not prove to have a significant influence on fatigue development, and neither did work experience or physical exercise. Conclusion: An amalgamation of numerous contributing factors within the work situation, private situation, and the individual influenced the development of fatigue, where there was no primary causal factor. Future studies should consider recording the accuracy of the sorting performance to acquire rich, objective data. , Thesis (MSc) -- Faculty of Science, Human Kinetics and Ergonomics, 2023

- Description: Poor water governance practices have been identified as one of the root causes of water problems confronting the South African water sector. This is evident in the lower section of the Upper Vaal River Catchment, where ineffective implementation of the regulatory measures has resulted in multiple incidents of illegal discharge of effluent from municipal wastewater treatment works, industrial and mining activities. Pollution and deterioration of water quality is a major challenge in the catchment; the Vaal River is severely polluted beyond acceptable standards and impacts negatively on other water users who have legitimate rights to the water resources. Pollution not only affects human activities and use, but also has negative impacts on ecological health and functionality. Poor water governance practices raise ethical implications for the rights to water for both social and ecological components. Although many water governance challenges in South Africa have implications that border on values and ethics, the relationship between these concepts has hardly been explored. In order to contribute towards filling this gap, this study explores water governance challenges and their ethical implications, and then analyse the equity dimensions of key water challenges among institutional actors in the lower section of the Upper Vaal WMA, Gauteng. The study uses a qualitative research approach which involves several methods of data collection: document analysis, workshops, focus group discussions, key informant interviews and participant observation. The data collected were analysed using thematic analysis, and then applied an ethical framework to distil ethical implications of the identified water governance challenges. There are five water governance challenges that were identified, which are i) failure in the implementation of water legislation and regulations, ii) ineffective leadership and management, iii) cooperative governance and poor accountability, iv) decentralisation and ineffective participation, and v) finance, infrastructure, and technical capacity. The deterioration of water quality and pollution due to ineffective implementation of the regulatory system has ethical implications towards protection of the ecological system and sustainable management of the water resources for the present and future generation. Ineffective implementation of the regulatory measure also raises the issue of distributive equity between different water users and between current and future users. These implications are critical particularly when viewed from the perspective of systemic-relational ethical approach which posit that in social-ecological systems, all components ought to be treated with equal regards, and their inherent worth respected in order to maintain the unity of the SES. The idea of equal regards to the inherent worth of the component implies due respect, in ways that do not undermine the integrity of the entire system. The challenges identified in the system suggest that i) the right of the ecological system to water is undermined due to anthropogenic activities, which may in the long term undermine the functionality of the entire SES; ii) the right of the margined to access to water of the right quality is also undermined, and pollution costs is externalised. These are matters of ethics that thus deserved attention in policy and management considerations. The study analysed equity dimensions (distributive and procedural), targeting the key institutional water users (i.e., mines, industries, agriculture, municipalities, and the wastewater treatment works) in the lower section of the Upper Vaal River Catchment as equity candidates due to their activities that significantly impact the environment and the water resources. The cost of pollution caused by mining activities, industrial activities and the wastewater treatment works is externalised to other users who are not responsible for the pollution. In this regard study identified key drivers that raise concerns linked to distributive equity, which are ) pollution and water quality deterioration, ii) the legacies of mining activities, and iii) poor infrastructure maintenance, vandalism, and theft. Identifying these key drivers of distributive equity concerns is critical in ensuring that the water governance processes are designed in a way that stakeholders and actors reliant on water resources within the catchment have equitable and fair access without the effects of externalised costs from other actors. The identified water governance challenges in the catchment all borders on ethics, thus an ethical framework is crucial in tackling water related problems. The principles of ethics can be used as guidelines to decision-making process for the management and governance of water resources in South Africa. Therefore, implementing and incorporating principles of the systemic-relational ethics into policy making and water resources management will yield sustainable, efficient, and equitable use and management of water resources. , Thesis (MSc) -- Faculty of Science, Institute for Water Research, 2023

- Description: The popularity of the web has seen various fields, such as the sciences taking advantage of this resource to further their scientific endeavours. This has seen science groups moving into developing websites and web applications, and such a group is the Research Unit in Bioinformative (RUBi). With the use of the web, the development and maintenance of whatever web-related tools become inevitable, given the continuous changes in the web space. This continuous evolution of web development and maintenance will come with techniques, principles and standards which will not only enable faster development of web entities but also ensure that modern hardware, fulfilment of the requirements to use such hardware and modern concepts are incorporated into forming web tools that enable such progression. Furthermore, introducing the previously mentioned progress of the web becomes an essential part of its development and maintenance. This paper did implement the processes of progressing the web using the technique of documentation and version control systems. The web development for the COVIDRUG website was done for the Covidrug-Africa Consortium (COVIDRUG) using the Django webdevelopment framework. The RUBi website and the MDM-Task we band the Job Management System (JMS) web applications were maintained for the maintenance aspect. Archives brought value regarding the traceability it provides of the various web-related aspects. The development showed a website’s potential value, particularly for research groups. The maintenance carried out showed how different techniques and approaches could be used in different maintenance prospects to achieve set objectives. The development and maintenance resulted in websites and web applications that have the features stated in their respective maintenance plans. , Thesis (MSc) -- Faculty of Science, Biochemistry and Microbiology, 2023

- Description: Intro: Accidents are complex in nature with multiple contributing factors. The way in which accidents are investigated is important and using system-based analysis tools assists in understanding and mapping these contributing factors to learn from them. There has been an increase in the number of accidents that have occurred within the general aviation industry in South Africa and while accident investigations have been undertaken, these have not included the application of system-based analysis tools. This led to a collaboration between Rhodes University and the Accident and Incident Investigations Division (AIID) of the South African Civil Aviation Authority where it was agreed that two systems-based analysis tools will be applied to a previously investigated accident that occurred in 2015. Aims: The first aim of this thesis was to identify if, through the implementation of these systems-based tools, the systemic contributory factors could be determined using the existing report by the AIID. The second aim of this thesis was to identify if, using the two systems-based tools, the actors and levels involved in the accident could be identified and the third aim was to identify if the implementation of these tools generates the same or different recommendations to that of the AIID. Methods: The two systems-based analysis tools applied were AcciMap and Causal Analysis using Systems Theory (CAST). These tools were applied to the V5-NRS Cessna 441 Conquest II accident report which captured the details of how the aircraft flew into the Tygerberg mountain on its descent into the Cape Town International Airport in August 2015. Results: Through the application of these two systems-based analysis tools the major contributing factors elucidated throughout this analysis were: visual and lighting conditions, pilot experience, training, lack of terrain warning equipment, fatigue, inadequate oversight, and inadequate risk management. In line with these findings, the analysis revealed various actors across various levels (the crew; South African Air Traffic Control, the SACAA, WestAir (the operator) and the Namibian Civil Aviation Authority Through the elucidation of these factors at various levels, 14 to 15 different recommendations were generated which was more than the one recommendation that was generated by the AIID. Discussion: Even when applied to an existing report, both the CAST and Accimap tools were able to bring to light the systemic contributing factors to this accident and importantly, highlight the role that various actors and levels within the system had in this unfortunate event. Consistent with previous literature, most of the contributing factors were found at the lowest level (the crew in this case) and fewer, but key factors were identified at higher levels (management and regulator level). Importantly, the application of the systems tools facilitated a systematic and systemic analysis of this accident, which allowed for the generation of recommendations at all levels, not just at the operator level. Conclusion: This study demonstrates the benefits and importance behind implementing a systems-based analysis method to an accident as these tools generate more useful recommendations which allows for important lessons to be learned following accidents, with the intention of re-designing systems to prevent them from happening again. , Thesis (MSc) -- Faculty of Science, Human Kinetics and Ergonomics, 2023

- Description: Difficulties arising from data scarcity, input data error or uncertainty, heterogeneous environments, lack of process understanding, and model structural uncertainty frequently constrain hydrological assessments of South African catchments. This research aimed to assess the usefulness of a “simpler” conceptual model for the conjunctive management of surface water and groundwater. The idea is that, to leverage the limited available data and information, a compromise between model complexity and data availability is required, which improves the use of models to produce reliable hydrological systems assessments. The research methodology focused on catchment-scale lake-groundwater dynamics to explore the limits of the groundwater components of the modified Pitman model (Hughes, 2004) in this type of environment, thus, determining the potential for using this model for integrated water assessments in South Africa. The Pitman model (Pitman, 1973; Hughes, 2013) is one of the most widely accepted models regarding surface water hydrology in South Africa; however, the newly incorporated groundwater components (Hughes, 2004) have not been applied as extensively as the surface water components. There remains uncertainty regarding their capability to adequately simulate groundwater processes and accurately represent surface and groundwater interactions in some environments. The model was assessed based on how well simulated water balance variables accurately reflected available evidence and expected catchment response (objective 1). Secondly, the research identified and addressed uncertainties as regards the structure and application of the model’s groundwater interaction components (objective 2). The model was set up for the Lake Sibaya catchment, which is a predominantly groundwater-driven system and, thus, provides an important opportunity to interrogate different aspects of uncertainty in both the conceptualizing and quantifying interaction processes. The study’s overall conclusion is that the model performed satisfactorily as it was able to simulate the lake’s water balance correctly enough such that the influences of dominating components were sensibly reflected in variations in streamflow and lake volumes. The following key findings were noted; (i) the lake volume shows a continuous decline, (ii) the lake volume decreased with increasing development (forestry and abstractions) in the lake catchment, (iii) there is significant rainfall uncertainty in the study area and the model showed high sensitivity to rainfall differences, (iv) robust conceptual knowledge of local catchment conditions was valuable for reducing some of the data related uncertainty in the study area and for producing realistic model simulations, (v) the Pitman model (Hughes, 2013) updated GW components can provide a valuable tool for modelling integrated hydrological processes; nevertheless, when applying the model to specific environments, implicit approaches may be necessary to account for processes that are not fully represented in the model. , Thesis (MSc) -- Faculty of Science, Institute for Water Research, 2023

The model was set up for the Lake Sibaya catchment, which is a predominantly groundwater-driven system and, thus, provides an important opportunity to interrogate different aspects of uncertainty in both the conceptualizing and quantifying interaction processes. The study’s overall conclusion is that the model performed satisfactorily as it was able to simulate the lake’s water balance correctly enough such that the influences of dominating components were sensibly reflected in variations in streamflow and lake volumes. The following key findings were noted; (i) the lake volume shows a continuous decline, (ii) the lake volume decreased with increasing development (forestry and abstractions) in the lake catchment, (iii) there is significant rainfall uncertainty in the study area and the model showed high sensitivity to rainfall differences, (iv) robust conceptual knowledge of local catchment conditions was valuable for reducing some of the data related uncertainty in the study area and for producing realistic model simulations, (v) the Pitman model (Hughes, 2013) updated GW components can provide a valuable tool for modelling integrated hydrological processes; nevertheless, when applying the model to specific environments, implicit approaches may be necessary to account for processes that are not fully represented in the model. , Thesis (MSc) -- Faculty of Science, Institute for Water Research, 2023
