- Description: Cobalt phthalocyanine (CoPc), cobalt tetracarboxy phthalocyanine (CoTCPc) and cobalt octacarboxy phthalocyanine (CoOCPc), adsorbed onto glassy carbon electrodes, have been used for the electrocatalytic detection of nitrite, L-cysteine and melatonin. The modified electrodes electrocatalytically detected nitrite around 800 mV vs.Ag|AgCl, a value less positive compared to that of an unmodified glassy carbon electrode (at 950 mV vs.Ag|AgCl) and also gave detection limits in the 10-7 M range for nitrite detection. L-cysteine was detected by the modified electrodes at potentials between 0.50 to 0.65 V vs.Ag|AgCl, with L-cysteine detection limits also in the 10-7 M range. The detection limits for melatonin ranged from 10-7 to 10-6 M. CoPc-modified electrodes displayed good separation of interferents (tryptophan and ascorbic acid) in the presence of melatonin. Analyses of commercial melatonin tablets using modified electrodes gave excellent agreement with manufacturer's value for all modified electrodes of this work.

- Description: This study is located in Mlungisi Township of Komani in the Eastern Cape - where the aim was to closely examine the role played by this community to build and govern its public schools. The study selected the three biggest schools in the area to examine how the community’s involvement in them has surfaced from their founding up to the present times. The study found that through these three schools, this community managed, under apartheid, to take initiative by mobilising itself for self-development by building these schools and infusing them with a liberation curriculum that was required for the conditions of oppression and resistance at the time. This community in essence turned the intentions of Bantu education around by using these schools as sites of alternative education that was delivered by its own activist teachers to conscientise the student youth about community struggles. Black people in this community used these schools as emancipatory spaces to connect student struggles with community struggles to build community power. In the post-apartheid epoch, much of these traditions and levels of community participation have dropped because of new precarious economies and labour conditions that keep the adult population busy. As a result, present-day community participation is not as politically intentional as it was under apartheid. Theoretically, the study applied Paulo Freire’s Critical Community Pedagogy. Methodologically, the study utilised critical qualitative oral histories and semi-structured interviews. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2023

- Description: The ways in which xenophobia continues to express itself in South Africa deserve to be noted at an advanced study. Over the past 15 years the expressions of xenophobia have been accompanied by increased deaths, more discrimination, increase of stereotyping of people of African descent and increased violence towards non-nationals, especially in the poorer parts of South Africa. Many of such xenophobic expressions have gone unnoticed and where they have been noticed, they have received little attention, leading to the exacerbation of the problem. The researcher of this study dwelt on a socio-legal analysis of xenophobia in South Africa. Appreciating the legal connotations and the expressions of xenophobia in South African society is a major concern of this study. To fulfill the objectives of this study, the researcher explores the extent and expression of xenophobia, in addition to analyzing and assessing the efficacy of legislative and other measures aimed to protect non-nationals in South Africa. The study investigates the role of state organizations, government and civil society and evaluates the impact of xenophobia on the enjoyment of human rights by non-nationals. A central objective of this study was to suggest alternative ways of explaining and understanding xenophobia and the responses to it. Empirical research was conducted to explore the extent of xenophobia in South Africa and how and why it is manifested in the way it is. Through in-depth face-to-face interviews it was revealed that the extent and manifestation of xenophobia differs in relation to particular communities, economic set ups and social settings; with poor communities being the most vulnerable to violent xenophobic attacks. Further, it was interesting to note that people have no firm understanding of what xenophobia entails as a social, legal, political and economical phenomenon. Again, it became evident that xenophobia still manifests in a country founded on values of equality, dignity and justice. Moreover, it was established that there is a weak link between law, human action and human behavior. It also became evident that education and sensitization need to be employed if xenophobic perceptions and behaviors are to be sufficiently dealt with. Recommendations were provided upon completion of the study. These included developing the law consciously, thus ensuring that the law has public legitimacy; effective law enforcement and prosecution; human rights education and training (especially in government departments, civil society organizations and institutions of learning); use of media and other communication channels to advocate for non discrimination, equality and respect for human rights, values and integration. Finally, the fight against xenophobia, racial discrimination and other related forms of intolerance needs to be taken up by all members of South African society and Africa at large. , Thesis (LLM) -- Faculty of Law, 2011

- Description: In this paper we report on the synthesis and characterization of 1,4-benzene diamine (BDA) functionalized single walled carbon nanotubes linked to cobalt (II) tetracarboxy-phthalocyanine. The characterization of the conjugate was through UV–vis, FTIR and X-ray diffraction (XRD) spectroscopies and by transmission electron microscope (TEM) and electrochemical methods. The conjugate is used for the electrochemical characterization of diuron. The catalytic rate constant for diuron was 4.4 × 103 M−1 s−1 and the apparent electron transfer rate constant was 18.5 × 10−6 cm s−1. The linear dynamic range was 1.0 × 10−5–2.0 × 10−4 M, with a sensitivity of ∼0.42 A mol−1L cm−2 and a limit of detection of 0.18 μM using the 3δ notation.

- Description: The benefits of participating in sport have been well documented and great emphasis has been placed on the role that it plays in the development of character and social skills, apart from physical and psychological benefits. Sport represents an optimal means of enabling children and adolescents to meet their daily requirements for physical activity to maintain health. Conversely, despite all of the widely acknowledged benefits, participation in sport among children and adolescents continues to decline throughout the world. Although a great deal of research has been conducted to identify barriers to participation in sport, most of it has concerned poor, rural, disadvantaged, or other marginalised groups. As a consequence, a large proportion of the research has attributed low rates of participation in sport to practical barriers, which usually take the forms of either logistical problems or a lack of resources. The aim of this study was to identify the barriers to participation in sport among adolescents in an affluent, urban setting, at an international school in Cape Town, South Africa. The Barriers to Sport Participation Questionnaire was used to identify the social, personal, and practical barriers that affected 107 adolescents who were enrolled in the school. The data was analysed by means of the SPSS (IBM, Version 27) software package and seven significant barriers were identified. Fear of academic failure, environmental constraints, and lack of interest were identified as the primary barriers, thereby emphasising the significant influence of personal barriers, rather than practical ones. It was also found that the influence of particular barriers was greater on females than their male counterparts and that the respondents who either did not participate in sport themselves or were from households in which other members did not do so were more adversely affected by some barriers than the others. Significant correlations were found between some grades and certain barriers, the most notable being those between respondents in Grades 7, 9, and 10 and the fear of academic failure barrier. In light of these findings, it could be concluded that the global decline in participation in sport among the youth is a complex problem and that particular barriers, which might not have been identified in previous research, could be particularly influential in affluent environments. As it is evident that as barriers can be specific to particular groups and settings, the optimal means of overcoming them is unlikely to be found through the adoption of a one-size-fitsall approach. Instead, further research and customised interventions are required. , Thesis (HMS) -- Faculty of Health Sciences, 2021

- Description: The concept of work engagement has become increasingly important in modern day organisations due to the impact of engagement on productivity, absenteeism, retention and general employee well-being. Organisations with the ability to nurture and improve the engagement levels of their employees are able to prosper as sustainable, competitive and adaptive organisations. The aim of this research is to determine which factors influence engagement of employees in South Africa and specifically in the aquaculture arena, which predominantly employs unskilled and semi-skilled people. A quantitative research design was applied to determine the work engagement levels of employees in an aquaculture organisation in the Eastern Cape, South Africa. Participants were requested to complete the Utrecht Work Engagement Scale as well as a biographic questionnaire. Engagement levels of different biographic groups were compared. Results indicate that there is a statistical and practical significant difference in the engagement levels of employees from different biographic groups. Older employees and employees with tertiary qualifications reported higher engagement levels. Female employees also indicated significantly higher engagement levels than their male colleagues. There are significant differences in the engagement levels of employees from different work sections and different lengths of service. Many of the differences in engagement levels can be explained in terms of the Job Demands-Resources Model. The difference in engagement level between respondents from different work sections may be due to differences in leadership style of the section supervisors. The scope of this study is not sufficient to explain the reasons for differences and more research in this area is recommended. The diverse employment landscape in South Africa requires more than a “one-size fits all” approach to managing employee engagement. This research adds to the body of existing literature on engagement in the South African labour landscape and provides valuable information to organisational leaders and Human Resource Managers when planning employee engagement initiatives. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business Administration, 2021

- Description: The study aimed to explore and describe the clinical experiences of newly qualified professional nurses in hospital facilities of the Alfred Nzo District Municipality in the Eastern Cape. The newly qualified professional nurses may face difficulties in the hospital facilities when it comes to the execution of duties. The newly qualified professional nurses are expected to display knowledge, skills and to have a positive effect on patients, the relatives of patients and their colleagues to alleviate diseases. This challenge may create emotional distress if newly qualified professional nurses receive inadequate guidance from the senior staff members of the hospital facility. The objectives of this study were to explore and describe the clinical experiences of newly qualified professional nurses, to explore how the newly qualified professional nurses were affected emotionally by clinical experiences and to explore the support system to enhance the performance of the newly qualified professional nurses. A qualitative, explorative, descriptive and contextual design was used to explore and describe the experiences of the newly qualified professional nurses in hospital facilities of the Alfred Nzo District Municipality in the Eastern Cape. A purposive sampling of newly qualified professional nurses, with less than two years of experience after completing the community service in the clinical practice, was used. The data were collected through face-to-face and semi-structured interviews. The interviews were conducted until the data were saturated. A pilot study was done before the main study to prove the adequacy and suitability of the methods to conduct the main study. The participants‟ interviews and results of the pilot study were incorporated into the interviews and results of the main study. Tesch‟s method of thematic analysis and an independent coder were used to analyse the data and to draw meaning from the content. The study used Guba and Lincoln‟s criteria of measures to ensure trustworthiness, which included credibility, confirmability, dependability and transferability. Ethical standards were maintained throughout the study as the researcher complied with ethical principles, namely, respect for persons, beneficence, justice and autonomy. The key considerations to curb the spread of the Covid-19 pandemic, as stipulated by the World Health Organisation, were followed during the data collection. On data interpretation, three themes were developed with eight subthemes on the first theme, two subthemes on the second theme and three subthemes on the third theme. The research findings revealed that the participants experienced negative attitudes from colleagues and multidisciplinary team members. The shortage of staff and resources made participants feel ineffective in their work environment. Clinical exposure to different units and procedures in various units added value to the development of the participants. The recommendations were made with regards to three divisions. They were the hospital facilities‟ personnel, future nursing research personnel and nursing schools personnel. In hospital facilities, the recommendations included that all novice professional nurses should be made aware of the emotional impact at work. An annual plan for workshops and in-service training should be implemented. Professional counselling is required for the novice professionals who were exposed to Covid-19 isolation units. A need to increase staff coverage in the clinical units was identified as the workload is too big. Management is encouraged to be more sensitive about the newly employed nurses‟ challenges in their facilities and the most experienced nurses are encouraged to mentor and coach the novice nurses. In the future nursing research, recommendations included that more studies need to be conducted in South Africa and the Eastern Cape province to verify the findings of this research. A specific research study that will focus on the supportive needs of nurses in clinical facilities should be done institutionally to provide evidence-based practice. The research culture on the nurses‟ experiences in clinical facilities needs to become a norm. In nursing schools, the recommendations motivated that the nursing students should be exposed to all clinical units before completing the training xiv course. Further studies need to be conducted to evaluate the balance between theory and clinical learning on duly performance. The nursing education institutions should use quality improvement suggestion boxes for students to consider their experiences and opinions about their learning.

In hospital facilities, the recommendations included that all novice professional nurses should be made aware of the emotional impact at work. An annual plan for workshops and in-service training should be implemented. Professional counselling is required for the novice professionals who were exposed to Covid-19 isolation units. A need to increase staff coverage in the clinical units was identified as the workload is too big. Management is encouraged to be more sensitive about the newly employed nurses‟ challenges in their facilities and the most experienced nurses are encouraged to mentor and coach the novice nurses. In the future nursing research, recommendations included that more studies need to be conducted in South Africa and the Eastern Cape province to verify the findings of this research. A specific research study that will focus on the supportive needs of nurses in clinical facilities should be done institutionally to provide evidence-based practice. The research culture on the nurses‟ experiences in clinical facilities needs to become a norm. In nursing schools, the recommendations motivated that the nursing students should be exposed to all clinical units before completing the training xiv course. Further studies need to be conducted to evaluate the balance between theory and clinical learning on duly performance. The nursing education institutions should use quality improvement suggestion boxes for students to consider their experiences and opinions about their learning.

- Description: This study stems from my experiences as a child who grew up playing herd boys’ musical instruments from Venda, such as the tshipotoliyo (ocarina), and tshitiringo (flute). Importantly it also builds on my time working at the International Library of African Music (ILAM,) where the aforementioned instruments, as well as the dende (musical bow) and tshizambi (Vhavenda and Vatsonga mouth bow), are displayed in transparent glass cubicles with a note, “Do not touch, they are fragile”. This phrase is painfully apt because, as a musician, I have observed a decline in the availability and performance of these musical instruments. The truth is that, other than at ILAM, these instruments are hardly in circulation, let alone being performed. This fact ignited my interest in relearning some of the musical instruments I used to play and make while herding cows in Giyani. In the context of trends such as modernisation, rural–urban migration, and globalisation, I document my experiences as a musical-instrument maker, teacher, and performer in revitalising dende, tshipotoliyo, tshitiringo, and tshizambi through classroom practice, using Rhodes music students, instrument-making workshops, performances, and community collaborations as inspiration. I propose the development of crafting skills as a medium for revitalising and sustaining these musical instruments which serve as important identity markers of the Vhavenda people. , Thesis (MMus) -- Faculty of Humanities, Music and Musicology, 2023

- Description: An intellectually safe classroom (ISC) is essential for teaching and learning to occur. The aim of this study was to investigate Grade 6 teachers’ views and practices regarding the creation of intellectually safe classroom environments. The paradigm that was used in the study was the interpretive paradigm and the research approach was qualitative. A case study design was used. Three Mdantsane primary schools was purposively selected and two Grade 6 teachers from each school were the participants. Semi structured interviews and observations were used to collect data. The research found that participants are cognizant of the need to develop ISC. They define ISC as a classroom that is both emotionally and physically safe for learning to occur. The participants are very conversant with the benefits of ISC. Most of the teachers purposefully tried to implement ISC. This included the establishment of classroom rules, and they acknowledged the role that the teacher plays in setting up an ISC and the manner in which they establish trust and co-operation within their classrooms. However, they are often constrained in their implementation of ISC by their own teaching styles and by factors outside of their control. This emphasised the pivotal role that teachers have in the establishment of an ISC. It is recommended that ISC be implemented in all classrooms with the entire school community working together to do so. , Thesis (MEd) -- Faculty of Education, 2019

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

- Description: The land question is a highly contentious issue in post-apartheid South Africa. Land is considered as a valuable resource for sustaining the livelihoods of people yet it remains one of the most sought after and contested resource in Africa owing to her colonial past. Black South Africans were also immensely subjected to land dispossession during the colonization by the Dutch and later the British and forced land removals during the apartheid era. Although this historical context from a lens of “race" is important to note here given how it shaped the South African geography of land ownership, there is nonetheless another dimension; that of gender. The main assertion driving this study is that due to a number of contextual factors (such as women's cultural status, economic inequality and poverty), land ownership between women and men is highly unequal whereby the former owns less and is mostly marginalized from land rights. This study thus looks at the extent to which land redistribution improves the quality of life for women in Buffalo City. The land redistribution program is part of the land reform policy which is a post-apartheid design and implemented for the purpose of redressing historical land dispossession and create redistributive land equality and tenure. This study employed a qualitative approach to ‘explore’ the experiences of women who are the beneficiaries of the land redistribution program as well as the perspectives of key informants who are the officials of the Rural Development and Reform Department. The thesis used an exploratory research design which was suitable for the understanding and unpacking of women's experiences with the land redistribution program. A major finding of this study is that the women who benefited from the land redistribution program have successfully progressed from small scale subsistence farming to large scale commercial farming, significantly improving their livelihoods. Nonetheless, the lack of financial capital is a critical challenge as the land redistribution program gives access to farms that need maintenance and renewal with financial grants that are barely enough for starting up. This study therefore argues that access to land should be accompanied by access to financial resources and capacity building to empower beneficiaries to use the land and other resources effectively and efficiently. It is recommended herein that the department should give beneficiaries full ownership of the land allocated to them as opposed to the thirty- year leasehold. , Thesis (MA) -- Faculty of Business and Economic Sciences, 2021

- Description: Despite the dire state of sanitation infrastructures, water scarcity, and the dwindling reserve of natural resources due to ever-increasing population growth, implementation of a suitable technology that can provide a solution to all these issues continues to be ignored. The integrated algal pond system (IAPS) is a wastewater treatment technology that combines the processes of anaerobic digestion and photosynthetic oxygenation to achieve wastewater treatment and facilitate the recovery of treated water and resources in the form of biogas and microalgal-bacterial biomass. The natural process of bioflocculation through microalgal-bacterial mutualism and production of extracellular polymeric substances (EPS) in high rate algal oxidation ponds (HRAOPs) of an IAPS increases efficiency of wastewater treatment and potentially enhances harvestability and biomass recovery, which could contribute significantly to the successful establishment of a biorefinery. Using a 500 PE pilot-scale IAPS supplied domestic sewage coupled with laboratory experiments, this study investigated the importance and function of in situ EPS production and MaB-floc formation in HRAOP. A metagenomic study revealed the biological components of the biomass or mixed liquor suspended solids (MLSS) produced in HRAOP and showed that the suspended biomass is composed largely of eukaryotes that were dominated by the colonial microalgae Pseudopediastrum sp. and Desmodesmus sp., and a diverse range of prokaryotes including bacteria and cyanobacteria. Dominance, within the bacterial population, by a sulphur-oxidizing bacterium, Thiothrix which comprised up to 80% of the prokaryotes, coincided with a period of poor flocculation and was therefore rationalized to have contributed to bulking and poor biomass settleability. Otherwise, good flocs were formed in the MLSS with settleability up to 95% and, within 1 h. The formation of MaB-flocs appeared to be dependent on EPS concentration of the mixed liquor due to the observed positive correlation between soluble EPS (S-EPS), biomass concentration, and settleability. The contribution and role of MLSS components towards the formation and sustenance of MaB-flocs were further demonstrated in laboratory experiments using pure strains of microalgae, cyanobacteria, and bacteria. Results showed that pure cultures of dominant microalgae in MLSS, Pseudopediastrum sp. and Desmodesmus sp. achieved a rapid 92 and 75% settleability within 3 h. A self-flocculating filamentous cyanobacterium, Leptolyngbya strain ECCN 20BG was isolated, characterized, and shown to achieve 99% settleability within 5 min by forming large tightly aggregated flocs. In further experiments, this strain was found to improve the settleability of MLSS by an average of 20%. Bacterial strains identified as Bacillus strain ECCN 40b, Bacillus strain ECCN 41b, Planococcus strain ECCN 45b, and Exiguobacterium strain ECCN 46b were also observed to produce sticky EPS-like materials in pure cultures that could also contribute to the aggregation of cells in a mixed environment. Given these results, various factors and/or mechanisms that might enhance microbial aggregation and biomass recovery from HRAOP MLSS were identified in this study and include; (1) dominance by larger colonial microalgae prevents disintegration of MaB-flocs and enhances recovery of biomass from MLSS by gravity sedimentation, (2) presence of filamentous cyanobacteria species that can self-flocculate to form an interwoven network of filaments may play an important role in the structural stability and settleability of MaB-flocs in MLSS, and (3) production of EPS to form the matrix or scaffold whereon all microbial components aggregate to develop a microenvironment. Indeed, all forms of EPS, except for that produced by Bacillus strain ECCN 41b, showed bioflocculating property and were able to serve as flocculants for the recovery of Chlorella, an alga known for its poor settleability. A combination of biochemical analyses and FTIR spectroscopy revealed the importance of carbohydrate enrichment of these biopolymers. Carbohydrate concentration in all forms of EPS was between 12 and 41% suggesting that production of these compounds by microbes within the MLSS contributed to MaB-floc formation. EPS extracted from bulk MLSS and EPS produced by Bacillus strains possessed some surface-active properties that were comparable to Triton X-100, indicating potential application in bioremediation and recovery of oil from contaminated soil and water. In particular, EPS generated from Bacillus strain ECCN 41b displayed relatively distinct properties including the quantity produced (> 500 mg/L), increased viscosity, inability to flocculate microalgal cells, a rhamnolipid content of 32%, and a higher surface-activity. Based on these results, Bacillus strain ECCN 41b was rationalized to produce anionic EPS with potential application in metal or oil recovery. In addition to EPS production, the bacteria Planococcus strain ECCN 45b and Exiguobacterium strain ECCN 46b appeared pigmented. Based on partial characterization using UV/Vis spectrophotometry, thin-layer chromatography, FTIR, and NMR, the pigments produced by these two strains appeared to be identical and were tentatively identified as ketocarotenoids. This study successfully demonstrated the importance of EPS production and formation of MaB-flocs in the MLSS from HRAOP of an IAPS treating domestic sewage. It is evident that increased settleability of the biomass does contribute to the reported efficiency of wastewater treatment by IAPS and would reduce both total suspended solids (TSS) and chemical oxygen demand (COD). In addition, demonstration that this biomass contains products of value such as carotenoids and EPS with potential for commercial use strengthens the idea of using IAPS as a platform technology for innovation of the wastewater treatment process to a biorefinery. , Thesis (PhD) -- Faculty of Science, Institute for Environmental Biotechnology, 2021

- Description: Community newspapers are an important source of information and play a vital role in the development of communities. They are, therefore, an important stakeholder in community development. IDike-Lethu community newspaper`s presence in the community of Alice and in the areas where it is distributed is facilitating communication and development in these areas. Raymond Mhlaba Local Municipality is benefiting in the presence of iDike-Lethu because this newspaper is the conduit through which communication to its citizens is submitted. This study assessed the challenges iDike- Lethu is having that impact on its maximum contribution in this society. Participants in this study are residents of Alice and are readers of iDike-Lethu Community Newspaper. This study adopted a mixed method design in which questionnaires and interviews were used to collect primary data. Data collected was analyzed using both qualitative and quantitative methods.

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

- Description: This study examines modalities of psychological trauma in selected works by three women writers from the global South: the Scottish-Sierra Leonean writer Aminatta Forna, the ChileanAmerican author Isabel Allende and Anuradha Roy from India. It aims to examine textual manifestations of complex and prolonged experiences of trauma and the ways in which literary forms facilitate such representations. Specifically, I am interested in multi-layered and interrelated forms of trauma which exceed the conventional, event-based conceptualization of trauma as an “overwhelming experience of sudden or catastrophic events” (Caruth 1996:11). 1 Such experiences include war, exile, extensive childhood sexual abuse, maternal bereavement and familial disintegration. I have selected three texts from each author’s body of literary work: Forna’s memoir The Devil that Danced on the Water: a Daughter’s Quest (2003) and her novels The Memory of Love (2010) and Happiness (2010), Allende’s memoirs Paula (1994), My Invented Country (2004) and Portrait in Sepia (2000) and Roy’s novels An Atlas of Impossible Longing (2008), Sleeping on Jupiter (2015) and All the Lives We Never Lived (2018). The study’s focus on women writers from different contexts in the global South is motivated by an imbalance in critical attention and validation extreme forms of suffering receive globally. , Thesis (PhD) -- Faculty of Humanities, School of Language, Media and Communication, 2020

- Description: Within the globalising trajectory of modernism, conservation, then environmental (EE) and now sustainability education (ESD) have each emerged as developing responses to risk produced by and in the modern state. Through adopting a long term process perspective, this paper narrates the emergence of situated learning perspectives and a developing re-orientation of EE at the start of the United Nations Decade of Education for Sustainable Development (UNDESD). We identified the need to examine ESD practice in responses to recent ESD consultations in 14 southern African countries, where a rhetorical marking was noted in discussions on ESD practices, particularly with regard to changing teaching and learning processes. The paper narrates how an interplay of review, research and practical engagement activities have all contributed to an extended critical review of learning interactions in environmental education in an attempt to provide useful perspective for educational activities within the UNDESD. We found that EE and ESD initiatives only acquired more substantive meaning and coherent orientation when examined within ongoing inquiries into situated learning, agency and risk reduction in contexts of poverty, vulnerability and risk, the key concern to us in this paper and the primary focus of the WEHAB (Water, Energy, Health, Agriculture and Biodiversity) sustainable development agenda in the region.

- Description: This work reports on the synthesis and amide bond linkage of carboxylic acid functionalized asymmetric zinc phthalocyanine (ZnPc) complexes to amino magnetic nanoparticles (AMNPs). The work further compares the photophysical and photochemical parameters of the Pc complexes alone with those linked to form ZnPc–AMNPs with further relation to the type of the spacer between the Pc and the AMNPs. Infrared spectroscopy confirmed the presence of the amide bond formed between the Pc complexes and the AMNPs. The triplet quantum yields ranged from 0.62 to 0.87. However, low singlet oxygen quantum yields were obtained due to competing pathways and the insufficient energy transfer from the excited triplet state of the ZnPc molecules to the molecular oxygen.

- Description: The 21st century has seen a dramatic increase in chronic non-infectious diseases, especially in the area of mental health. Medical anthropologists have seen a rise in the development of mental illnesses in both developed and developing nations. There is, however, little research conducted on trauma narratives that do not stem from political violence from an anthropological lens. South Africa has various understandings of trauma depending on the cultural context and it is crucial to examine these narratives as this provides vital information of the daily lived experiences of trauma survivors. Key themes draw on issues of trauma denialism, communicating distress, traumatic symptoms and the development of mental illnesses as a result of traumatic exposure. The data was analysed through Goffman’s (1959) Presentation of Self in Everyday Life illustrating various ways how survivors present themselves depending on the particular audience. This research employed both qualitative and quantitative research methods to gather a holistic understanding of trauma survivors. With the use of semi-structured interviews of Stressful Life Events Questionnaire coupled with observations of online support groups for trauma survivors, this research has provided rich ethnographic evidence of the impact that culture has on trauma narratives illustrating a clear normalcy of trauma present in South Africa. , Thesis (MSocSci) -- Faculty of Humanities, Anthropology, 2022
