- Description: No formal study on the incidence and extent of medullated and coloured fibres has been performed in South Africa. The purpose of this research project was to investigate the validity of the claims that there has been an increase in the production of wool contaminated with medullated and coloured fibres. Therefore, the main aim of this study was to determine whether the incidence and extent of medullated and coloured fibres in the South African wool clip have changed over time. Secondly, the study aimed to determine whether the incidence and extent of medullated and coloured fibres have a distinct geographic distribution. This study explored eight years of wool production records (2010 to 2017) obtained from BKB, the largest wool broker in South Africa. For the purpose of this research, the wool-producing areas of South Africa were divided into 6 regions, according to average annual rainfall, vegetation type and major farming practices applied in the area. Statistical analysis of the data included descriptive statistics, analysis of variance and post-hoc tests, as well as regression analyses. This study succeeded in quantifying the extent and prevalence of contamination with medullated and coloured fibres in the South African wool clip. The overarching conclusions were: • Floating kemp is the most important contaminant of wool in South Africa, with the incidence of harsh kemp and coloured fibres being very low. • Generally, the most important areas that need attention in combatting contamination in the South African wool clip, are the Mixed Farming Summer Rainfall Region, the Semi-Arid Grassveld and the High Rainfall Grassland. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: Only 12% of the world's published plastic research includes references to Africa despite it being a significant contributor to the global plastic waste and mismanagement problem (~88.5% of Africa's plastic waste is mismanaged). Ocean plastics are transported from land by rivers to the sea. However, source contextualization is complex. Many African rivers predominantly run alongside human settlements that host informal waste dumpsites. In this study a simple cost effective, easily deployed, consistent and replicable survey methodology was employed. The study quantified macro plastic in three rivers discharging into Algoa Bay, South Africa. The results indicated that industrial Swartkops and metropolitan Baakens Rivers both illustrate moderate plastic pollution (>3000 plastic particles/day), with the relatively natural Sundays River to showing minimal evidence of river macroplastic (<100 plastic particles/day). The types of plastic were noted using the RIMMEL app (premier African implementation), enabling proportional comparison of different plastic litter types to be completed. , Thesis (MSc) -- Faculty of Science, Oceanography Department,2021

- Description: The study examines the relationship between demarcation of municipal boundaries and the capacity of a municipality to deliver services. The case of the amalgamation of Baviaans, Camdeboo, and Ikwezi local municipalities which has led to the establishment of the Dr Beyers Naudè Municipality in the Sara Baartman District Municipality in the Eastern Cape has been used to determine this relationship in this study. The amalgamation of these municipalities has led to the redetermination and dismantling of their boundaries and the establishment of the boundaries of the newly created and larger Dr Beyers Naudè Local Municipality. The study investigated whether the demarcation of municipal boundaries has, in this instance, enhanced the capacity of the municipality to deliver basic services. Organisational Theory was used to interpret the amalgamation of municipalities. This theory was used for the theoretical basis of organisational structure and highlighting the need for the alignment of organizational structure with the municipalities’ mandate, of effective and efficient service delivery. The study adopted a qualitative research method and employed a non-probability purposive sampling technique to select participants. Interviews were used for data collection. 38 participants were interviewed, namely 7 councillors, 5 municipal officials, 5 members of the ratepayers’ association and 21 members of the community. Mixed views were expressed by participants regarding the enhancement of the state on basic service delivery after the merger of the three local municipalities. Furthermore, the study did not find evidence of a feasibility study prior to the implementation of the amalgamation process. Subsequently, the study could not find conclusive evidence relating to the enhancement of the capacity of the municipality to deliver services after the redetermination of municipal boundaries. The study recommends, among others, that the demarcation of municipal boundaries should be preceded by an appropriate feasibility study and be done such that there is compliance with the relevant legislation, and it must also have an effective public participation. The study also recommends that the newly established Dr Beyers Naudè Local Municipality should focus on maintaining the service delivery infrastructure it has inherited from the merger of its three predecessor municipalities, enhance public participation in its programmes, and priorities community beneficiation as a critical aspect of its service delivery mandate. , Thesis (PhD) -- Faculty of Humanities, School of Governmental and Social Sciences, 2021

- Description: Over the coming decades, Africa is expected to experience disturbing effects due to climate change and increased land cover change due to human influences presenting a significant concern for the future well-being of human and biological systems, the latter being the foundation of ecosystem services supplied to humanity. Therefore, unprecedented transdisciplinary cooperation, coordination, and integration amongst researchers, government, and civil society are necessary to increase the resiliency of these systems. This study aims to provide an outline of the Africa Alive Corridors (AAC) as an essential model for the encouragement of sustainable development through Earth Stewardship science. These aims are accompanied by the quantification and forward modelling for land cover change of the Critical Zone over 10 Great Lake Basins across one of the AAC, the Western Rift Valley Corridor (WRVC), in East Africa between the years 2018 and 2060. This approach provides the foundation for implementing improved regional governance, better encouragement of sustainable development beyond the 2030 United Nations Sustainable Development Goals, and education programs, such as the AAC, that promote socio-ecological resilience through Earth Stewardship Science. The AAC archives a portion of East Africa as the WRVC, a corridor along the western branch of the East African Rift System that highlights twenty heritage nodes, primarily great lakes, mountain ranges, national parks, and biological hotspots. These heritage entities are associated with ca. 12-million-years of evolution and transformation of the East African topography and related African Great Lake (AGL) systems. The thesis defines the study area by delineating AGL basins intersected by the WRVC. Across these basins, land cover change analysis provides a platform for an integrated assessment of the projected health of the corridor region. Existing land cover datasets provide the initial conditions of the study area for 2008 and 2013. Land cover between 2008 and 2013 is cross-tabulated using the Land Cover Module in the Terrset software, followed by the iii delineation of sub-models and driver variable identification. The Multi-Layer Perceptron algorithm provides the transition potentials between tree cover, urban area, cropland, wetland, and open area classes. Change quantification and prediction using Markov Chain analysis are then established for 2018, 2030, and 2060. The model successfully simulated future land cover change and concluded that: (1) proximity to existing human activity, proximity to existing tree cover, and population are the primary drivers of change; (2) the dominant land cover of the ten lake basins for 2018 was cropland at ca. 48%, followed by tree cover at ca. 33%; (3) total anthropogenic change over the coming four decades equates to over ca. 52 000 km2 (5 200 000 ha), and particularly (4) an urban area is expected to increase by >130%. This assessment ultimately provides a platform for regional governance development at the basin scale and Earth Stewardship science in East Africa. These changes require transdisciplinary action from researchers to civil society. The AAC provides the foundation for understanding the dynamics of the systems that support life across broader spatial and temporal resolutions in Africa, highlighting the need for future generations to build socio-ecological resilience to anticipate challenges such as biodiversity loss posed by climate change and excessive land cover change. , Thesis (DSc) -- Faculty of Science, School of Environmental Sciences, 2022

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

- Description: Accessibility to healthcare refers to the availability, or the provision of healthcare-byhealthcare professionals and stakeholders and individuals' ability to obtain care and treatment. It affects overall physical, social, and mental health; disease and disability prevention; detection and treatment of health conditions; standard of living; preventable death; and life expectancy, and it is crucial to the performance of health care systems around the world. If healthcare services are available and are in sufficient supply, people will be able to seek health care, and a population will have access to services. The leading cause of death globally is Tuberculosis (TB) and South Africa is amongst the top 5 countries most affected by TB. This is aggravated by high HIV/AIDS statistics. Children belowthe age of 4, between the ages of 4- 15, and women and men of working ages are highly affected by TB and it is the primary cause of death in these groups in the Ngaka Modiri Molema District. This study used study tools like Spatial Modelling, Geographic Information Systems and software like ArcGIS 10.5, TerrSet IDRISI 18.30, and secondary data from the North West Departmentof Health (Tier.net &DHIS) and also TB patients’ home addresses to investigate the accessibility of TB treatment in Ngaka Modiri Molema, in order to spatially visualize the distribution of a communicable disease like TB and public healthcare facilities in the Ngaka Modiri Molema (NMM) District and suggest optimum sites for hospital facilities. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: In many South Africa’s areas, citizen’s frustration with poor or slow service delivery has resulted in a surge of service delivery protests. Some of these service delivery protests are violent in nature, resulting in the damage of public and private property. Therefore, it is imperative to scrutinize service delivery protests. The South African constitution states that municipalities have the responsibility to make sure that all citizens are provided with services to satisfy their basic needs. These services include water supply, sewage collection and disposal electricity, gas supply health services, roads, storm water drainage, street lighting, municipal parks and recreation. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2021

- Description: Traditional Afrikaner culture has often been associated with conservative beliefs, giving patriarchal figures such as the husband and father superior status. Although South Africa has undergone social progression, large numbers in Afrikaner communities still live according to old, patriarchal norms.

- Description: Eskom Holding is a public limited liability company that supplies electricity. It supplies approximately ninety-nine percent of the electricity used in South Africa, and approximately forty-five percent of that used in Africa. Eskom generates, transmits and distributes electricity to its customers. The Project Execution Department is a department in the Transmission Division that executes the capital and refurbishment of projects. The objective of the study was to discover the opinion of the project team members, on whether there is a lack of project-team efficiency in delivering the projects on time, and within the budget. Descriptive research methodology was used to investigate the objectives of the research. The data were obtained through the structured questionnaires that were hand-delivered and emailed. The research is limited to the Project Execution and Procurement Department in the Transmission Division. The research excludes the Capital Expansion Department (CED) project (Medupi, Kusile and Power Development Projects). The findings of the study showed that, Eskom’s Transmission Project Execution and Commercial Departments need to work hand-in-hand. This will avoid any unnecessary procurement delays which would have an impact on project delivery time. Continuous communication among the project team members could improve the efficiency and serve to build good relationships. Currently, projects are delivered late and over budget. This situation could lead to the outsourcing of departments or even to the redeployment of Senior Management. It would also have a negative impact on the cost and supply of electricity to the country. , Thesis (MSc) -- Faculty of Engineering, the Built Environment and Information Technology, School of the Built Environment and Civil Engineering, 2021

- Description: Lithium-ion technology takes the lead in electric mobility systems, resulting in an increase in the global demand for Li-ion batteries; however, these batteries are associated with numerous safety concerns. Additionally, there are high costs, high energy and power issues which are some of its key limitations. Research efforts are focused on overcoming these obstacles, with different approaches being explored, such as the investigation of more stable salts, modification of active materials and organic solvents, and the use of electrolyte additives. This study focused specifically on electrolyte additives since the electrolyte is one of the most unstable components of the battery. The electrolyte’s decomposition is one of the reactions that occur inside a battery, which may occur due to overcharging or due to an internal short circuit, amongst others. The electrolyte’s decomposition occurs at the early stages of the thermal runaway process and forms part of the reactions that lead to fires and explosions. Thus, this research aims to develop suitable electrolyte additives to improve the safety aspects of Li-ion batteries. Flame retardant additives show great promise in reducing the flammability of the electrolyte in Li-ion batteries, since they serve to suppress the chemical reactions associated with battery ignition. They retard the fires by scavenging the active radical species formed during the decomposition reaction. In this study, the use of flame retardants was investigated. Flame retardant additives have shown to have flame impeding properties inside a battery; however, their direct addition to the electrolyte tends to cause adverse effects on the ionic conductivity and electrochemical performance of the cells. This study investigated an alternative option - the option to microencapsulate such additives into a neutral compound to ensure that the flame retardant has minimal/no effect on the performance of the battery. This investigation looked at tris(2-butoxyethyl) phosphate (TBP) and bis(2,2,2-trifluoroethyl) methylphosphonate (BFP) as flame retardant additives for the electrolyte. The TBP and BFP flame retardants were microencapsulated in poly(urea formaldehyde) (PUF) coating material via in situ polymerization method. The capsules were characterized using various analytical techniques - to prove it was successfully encapsulated. Electrochemical studies were further done on the capsules and neat flame retardants inside a coin cell. Self-extinguishing time (SET), which is the flammability test, proved that the additives have flame retarding abilities. Opto-digital microscopy (DSX) and scanning electron microscopy (SEM) did confirm the spherical shape of the microcapsules, where SEM also showed the smooth outer layer of the microcapsules and its hollow inner side. Fourier transform infrared spectroscopy (FTIR) proved the presence of the TBP and BFP inside the PUF resin by showing that the chemical composition of microcapsules consisted of both the PUF and flame retardant additives. Simultaneous DSC-TGA (DST) was also performed which showed that the microcapsules were stable before 200 °C, which indicates it would not decompose before the thermal runaway events are occurring. TGA analysis did show that the microcapsules underwent multiple decomposition steps upon heating. Additionally, 31P nuclear magnetic resonance (NMR) was used to quantify the amount of flame retardants additives encapsulated inside PUF shell, and also confirmed the stability of the microcapsules for one month in the electrolyte and at temperatures up to 200 °C. The ionic conductivity was vastly decreased when the flame retardants were added directly to the electrolyte. However, adding the flame retardants in a form of capsules had minimal effect on the ionic conductivity. The cycle capacities of the capsules were also improved when the capsules were added to the cell compared to that of neat flame retardants. The same effect was also noticed when doing Electrochemical Impedance Spectroscopy (EIS). This shows that microencapsulation improves the resistance of the cell caused by the flame retardant in comparison to when added directly to the electrolyte of the cell. , Thesis (MSC) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2022

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

- Description: The Post-Provisioning Model (PPM) is a Resource Allocation Model (RAM) used by the Department of Education to optimize the distribution of available educator resources to public schools. The Department of Education adopted the PPM to distribute the total available posts to all public schools in an “equitable, transparent and resource-efficient manner. The PPM is a formula-driven model that primarily allocates educators, as human capital, to public schools based on learner enrolment numbers. In addition to allocating teaching staff, the PPM allocates the School Management Team (SMT) to each school. The outcome of the PPM formula is called the Post-Provisioning Norm (PPN). The implementation of the PPM has presented various challenges in the management of public schools. The primary aims of this study were to investigate any possible weaknesses of the PPM and to critically evaluate and explore school managers’ views of the PPM in the management of public schools. For the purposes of this study a probability sampling procedure was used. The participants were chosen from the principals within the Department of Education in Amathole East District. The literature review undertaken and the field research findings in the fourth chapter revealed that there is a gap between the ideals of the PPM and its implementation. It was found that there was a poor understanding of the technical aspects of the PPM formula among senior managers of public schools. There is evidence of equitable quantitative distribution of posts through the PPM. However, it was discovered that the PPM does not take into account the distribution of qualified educators. Hence, some of the allocated posts in public schools were often filled by under-qualified or non-qualified staff. The appointment of qualified educators was skewed. Further findings of this study revealed, amongst others, the inability of the PPM to provide for and promote the needs of a diverse curriculum in rural areas, and the inability to factor in and balance the variable that some public schools raise more money in school fees, which enables the advantaged schools to employ additional educators. The primary recommendations of this study are that principals be trained, on an annual basis, on the workings of the PPM and that the South African Schools Act No.84 of 1996 should be amended to grant authority to the Head of Department of the province to appoint and deploy qualified educators to public schools. , Thesis (MPA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2020

- Description: The democratic legitimacy of African executives has been called into question substantially over the last decade. Using the Democratic Republic of Congo (DRC) as a case study, this evaluative research seeks to analyse how African executives and political elites continue to play a crucial role in inducing civil unrest and electoral violence. For African democracy to develop, there must be enforced resolutions to eradicate issues facing both procedural and substantive democracy on the continent. This research examined electoral violence and unconstitutional acts that aggravate electoral system abuse and diminish the consolidation of democracy in sub-Saharan African states, in particular the DRC. A specific focus on the leadership of Joseph Kabila in the DRC forms the case study component of this research. In 2016, elections were postponed in the DRC and the DRC’s constitutional court interpreted Article 70 and Article 73 of the constitution in a manner that allowed President Kabila to remain in office until a newly elected president was installed. The court’s ruling and interpretation of Article 70 and Article 73 was an attempt to avoid a power vacuum. The study evaluated the components that trigger the escalation of electoral violence in Sub-Saharan African states. The study reports on different contributory factors, including but not limited to, the impact of predatory and rent-seeking leadership towards electoral manipulation; and the effect of patron-client relations on democratic institutions. Even though elections are not the only indicator of democracy stability in a state, this study demonstrated how electoral violence threatens the consolidation of democracy in sub-Saharan African states, in particular the DRC. In examining electoral violence, a desktop analysis method, which was used in the study, involved the collection of data from existing resources in order to provide a more critical lens to understanding electoral violence in the DRC. The theoretical analysis used in the study is the Höglund (2009) framework on electoral institutions which outlined how political violence remains a pervasive feature in Sub-Saharan countries by linking the framework to patron-clientelism. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2020

- Description: The South Africa (SA) forest industry relies on plantations of exotic forestry trees (Pinus, Acacia and Eucalyptus) to fulfil its timber requirements. With 52.0% of the afforested land in South Africa planted to various eucalypts and their hybrid combinations. Of the total area planted to eucalypts in SA, 75 000 ha is re-established annually by means of silvicultural regimes and operations matched to site productivity, desired end-product and method of regeneration. Unlike other commercially grown tree species, eucalypt species have the ability to coppice after felling. Coppicing is a common form of regeneration in South African forestry as it allows the plantation owner the option of a second timber rotation without replanting. However, if any factors affecting coppicing are compromised, and the site is to be replanted, then it is important to kill the stumps before replanting as rapid initial growth of the coppice shoots will require earlier control than that associated with normal weeding operations. Over time, various methods of woody plant control have been proposed and tested, with most of these making use of herbicides as opposed to the repeated manual removal of coppice regrowth. Globally, most industries subscribe to standards associated with sustainable production (economic, environmental and social) against which they are measured. Within SA, 80% of the forests are certified though either the Forest Stewardship Council (FSC) or International Standards Organisation (ISO) which recommend the identification and avoidance of ‘highly hazardous’ chemicals; the promotion of ‘non-chemical’ methods for pest management as an element of an integrated pest and vegetation management strategy; and the appropriate use of chemicals that are used. To test the current recommendations for killing eucalypt stumps to include other species, the potential of reducing herbicides used, and the influence of time after application on the survival of eucalypt stumps, two trials were initiated at Entabeni plantation (Venda, Limpopo) and one at Wilgeboom plantation (Bushbuckridge, Mpumalanga) between 2018 and 2020. Extending eucalypt cut-stump control practices: Most of the trial work on killing of eucalypts in SA has been conducted on Eucalyptus grandis, Eucalyptus camaldulensis or Eucalyptus macarthurii, with all grown on shorter pulpwood rotations. To extend current recommendation to include Eucalyptus cloeziana (grown on a longer rotation for poles), a trial was established in 2018 at Entabeni plantation (Limpopo Province) to quantify the interaction between Application method (basal-frill; cut-surface; foliar) and Herbicide (no herbicide applied; Roundup; Garlon; Roundup + Garlon) for the killing of 12 year-old stumps following harvesting. Assessments were carried out at 1, 3 and 6 months following application and included Stump survival, Stump quarter with coppice and Coppice heath. Relative to the control plots (100% survival), all herbicides tested were equally effective, 70–90% of the stumps killed. This study confirms previous research regarding the killing of eucalypt stumps. Roundup, Garlon or a combination of two, when applied according to label recommendations to a stump as a basal-frill or cut-surface application (within 30 minutes of felling) resulted in 70-90% of the stumps killed. , Thesis (MSc) -- Faculty of Science, School of Natural Resource Management, 2021

- Description: The South Africa (SA) forest industry relies on plantations of exotic forestry trees (Pinus, Acacia and Eucalyptus) to fulfil its timber requirements. With 52.0% of the afforested land in South Africa planted to various eucalypts and their hybrid combinations. Of the total area planted to eucalypts in SA, 75 000 ha is re-established annually by means of silvicultural regimes and operations matched to site productivity, desired end-product and method of regeneration. Unlike other commercially grown tree species, eucalypt species have the ability to coppice after felling. Coppicing is a common form of regeneration in South African forestry as it allows the plantation owner the option of a second timber rotation without replanting. However, if any factors affecting coppicing are compromised, and the site is to be replanted, then it is important to kill the stumps before replanting as rapid initial growth of the coppice shoots will require earlier control than that associated with normal weeding operations. Over time, various methods of woody plant control have been proposed and tested, with most of these making use of herbicides as opposed to the repeated manual removal of coppice regrowth. Globally, most industries subscribe to standards associated with sustainable production (economic, environmental and social) against which they are measured. Within SA, 80% of the forests are certified though either the Forest Stewardship Council (FSC) or International Standards Organisation (ISO) which recommend the identification and avoidance of ‘highly hazardous’ chemicals; the promotion of ‘non-chemical’ methods for pest management as an element of an integrated pest and vegetation management strategy; and the appropriate use of chemicals that are used. To test the current recommendations for killing eucalypt stumps to include other species, the potential of reducing herbicides used, and the influence of time after application on the survival of eucalypt stumps, two trials were initiated at Entabeni plantation (Venda, Limpopo) and one at Wilgeboom plantation (Bushbuckridge, Mpumalanga) between 2018 and 2020. Extending eucalypt cut-stump control practices: Most of the trial work on killing of eucalypts in SA has been conducted on Eucalyptus grandis, Eucalyptus camaldulensis or Eucalyptus macarthurii, with all grown on shorter pulpwood rotations. To extend current recommendation to include Eucalyptus cloeziana (grown on a longer rotation for poles), a trial was established in 2018 at Entabeni plantation (Limpopo Province) to quantify the interaction between Application method (basal-frill; cut-surface; foliar) and Herbicide (no herbicide applied; Roundup; Garlon; Roundup + Garlon) for the killing of 12 year-old stumps following harvesting. Assessments were carried out at 1, 3 and 6 months following application and included Stump survival, Stump quarter with coppice and Coppice heath.

- Description: A series of core-functionalized borinic acids was synthesized from Grignard reagents and tributylborate and reacted with ethanolamine, amino acids, 2-pyridylmethanol as well as 2-(ethyl amino ethanol). Among the borinic acids synthesized were the ones bearing: para-(2, 15, 16, 22, 27)-methyl, (3, 20, 25)-chloro, (4, 23, 26)-fluoro, (5)-methoxy; meta-(7, 17)-methyl, (9)-fluoro; ortho-(6)-methyl, (8)-chloro, (10, 18, 19)-methoxy substituents on their respective aromatic systems. All compounds obtained by condensation of the borinic acids with the aforementioned nitrogen-containing substrates were characterized structurally by means of diffraction studies based on single crystals and found to constitute chelate esters/amides featuring covalent B-O and dative N→B bonds. The chelate compounds researched in this study could be classified into four families and represent the compounds: ethanol amine: (1) 2,2-diphenyl-1,3,2-oxazaborolidines, (2) 2,2-bis(p-tolyl)-1,3,2-oxazaborolidines, (3) 2,2-bis(p-chlorophenyl)-1,3,2-oxazaborolidines, (4) 2,2-bis(p-fluorophenyl)-1,3,2-oxazaborolidines, (5) 2,2-bis(p-methoxyphenyl)-1,3,2-oxazaborolidines, (6) 2,2-bis(o-tolyl)-1,3,2-oxazaborolidines, (7) 2,2-bis(m-tolyl)-1,3,2-oxazaborolidines, (8) 2,2-bis(o-chlorophenyl)-1,3,2-oxazaborolidines, (9) 2,2-bis(m-fluorophenyl)-1,3,2-oxazaborolidines, (10) 2,2-bis(o-methoxyphenyl)-1,3,2-oxazaborolidines. α-amino acids : (14) 4-methyl-2,2-diphenyl-1,3,2-oxazaborolidin-5-ones, (15) 2,2-bis(p-tolyl)-1,3,2-oxazaborolidin-5-ones, (16) 4-methyl-2,2-bis(p-tolyl)-1,3,2-oxazaborolidin-5-ones, (17) 4-isopropyl-2,2-bis(m-tolyl)-1,3,2-oxazaborolidin-5-ones, (18) 4-methyl-2,2-bis(o-methoxyphenyl)-1,3,2- oxazaborolidin-5-ones, (19) 4-acetamidyl-2,2-bis(o-methoxyphenyl)-1,3,2- oxazaborolidin-5-ones, (20) 4-phenylethane-2,2-bis(p-chlorophenyl)-1,3,2 oxazaborolidin-5-ones. 2-pyridylmethanol: (21) 1,3-hydroxypyridyl-2,2-diphenyl 1,3,2-oxazaborolidines, (22) 1,3-hydroxypyridyl-2,2-bis(p-tolyl)-1,3,2-oxazaborolidines, (23) 1,3-hydroxypyridyl-2,2-bis(p-fluorophenyl)-1,3,2-oxazaborolidines 2-(ethyl amino ethanol): (24) 3-ethyl-2,2-diphenyl-1,3,2-oxazaborolidines, (25) 3-ethyl-2,2-bis(p-chlorophenyl)-1,3,2-oxazaborolidines, (26) 3-ethyl-2,2-bis(p-fluorophenyl)-1,3,2-oxazaborolidines, (27) 3-ethyl-2,2-bis(p-tolyl)-1,3,2-oxazaborolidines. Apart from structural studies in the solid state, the compounds were also characterized by means of multinuclear NMR spectroscopy (1H, 11B, 13C) as well as UV/vis and FTIR. The typical 11B resonances were found in the range of (4-10 ppm). A series of characteristic metrical parameters for the compounds in the solid state as well as typical NMR shifts for the chelate target molecules was established that allowed for the determination of the coordination induced shift. The carbon atom bonded to the oxygen atom shifted upfield, while the carbon atom bonded to the nitrogen atom shifted downfield. Factors mentioned in the literature that has an influence on the hydrolytic stability on the heterocyclic borinate motif have been taken into consideration and verified for the systems researched in this study. The substitution at the nitrogen atom with one ethyl group caused the greatest increases in the N→B bond length (27) 1.714 Å, due to the increase in the nitrogen Lewis basicity, making it the least hydrolytically stable, these include compounds (24-26). Furthermore, DFT calculations were performed by employing Becke’s three parameter hybrid exchange functional with Lee–Yang–Parr functional (B3LYP) method using the Gaussian 16 program package (Rev. B01) employing the basis set 6-311++G(d,p), to corroborate and correlate the experimental findings, which gave a general R-squared value of 0.9978 for calculated vs experimental 13C chemical shifts. Thermal properties are recorded for select compounds, indicating the ΔH and the melting points. , Thesis (PhD) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2021

- Description: The aim of the study was to evaluate the implementation of the Expanded Public Works Programme (EPWP) in the Buffalo City Metropolitan Municipality (BCMM) between 2013 and 2018. This was necessitated by the common trend observed in the country that, despite many interventions to alleviate poverty, the unemployment rate continues to increase, and poverty remains a challenge. The study was qualitative, and it used secondary data to achieve its objectives. The data was sourced from journals, municipal documents, the national Department of Public Works’ publications, newspapers and many other secondary sources. The results revealed that the EPWP performance in BCMM is greatly influenced by effective performance management systems, proper planning, political impact, training and development, and committed leadership. This was perceived as the first attempt towards improving the EPWP aligned employment statistics in BCMM. These results were found to be very important in helping an organisation to achieve employment targets. Furthermore, the municipality should investigate strengthening its consultative processes to involve the public in the job creation and decision-making processes. , Thesis (MPA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2020

- Description: Ocean health provides the foundation for human health through the provisioning of ecosystem services. Increasing demands on ocean space and resources are, however, resulting in a decline in ocean health, with direct and indirect knock-on effects on marine uses and ultimately on human health. In response, there is a growing need to acknowledge and better manage complex human-ocean interactions. This has been recognised in global sustainable development goals and in integrated ocean management processes, leading to widespread endorsement of an ecosystem-based marine spatial planning (MSP) process, including in South Africa. In support of the national MSP process, significant progress has been made in understanding the spatial extent of marine activities and associated marine pressures, but the temporal dynamics of marine activities and interconnections with the marine environment are less well understood. To plan for the growth of marine activities and associated user conflicts, the drivers of these temporal dynamics and associated feedback effects need to be analysed and potential policy and management interventions identified and tested. To support South Africa’s national MSP process, this study adopts a systems analysis approach, using system dynamics modelling, to explore the temporal change in marine uses under alternative growth scenarios in Algoa Bay. Algoa Bay is an appropriate study area because it is experiencing a rapid expansion of marine activities, coupled with a growing uncertainty regarding marine sustainability outcomes. To assist future marine management decisions, the Algoa Marine Systems Analysis Tool (Algoa MSAT) was developed, comprising seven sub-models. Five of the sub-models represent selected marine uses in Algoa Bay, whereas the sixth and seventh integrate the outputs from each marine use in terms of sustainable management indicators (marine health, marine wealth and marine labour). Model development primarily adopted an expert-based model ling approach, although the involvement of stakeholders, through a collaborative modelling process, assisted in integrating knowledge on different marine sectors’ activities, impacts and planning visions into the model framework. Model results were generated under different scenarios to investigate changes in the growth of marine activities and marine sustainability indicators under different levels of ocean governance. Under the baseline (or business-as-usual) model scenario, marine activities were shown to grow increasingly within their respective management limits, with an increase in marine wealth and labour and a consequential decrease in marine health. This scenario particularly highlights that current ocean governance practices are ineffective in sustaining the projected growth of the marine uses, particularly for those that are vulnerable to negative changes in marine health. Conversely, sectors that hold more value in marine wealth and are more resilient to changes in marine health, may continue to grow regardless of negative knock-on effects of the health of the marine environment and on other uses in the bay. This emphasises that an alternative governance strategy is needed to achieve the long-term goal of an ecosystem-based MSP process, as required by South African MSP legislation. To achieve this will require multiple, adaptive cross-sectoral management interventions that are directed towards the ‘deeper leverage points’ that are able to maintain the growth of marine activities within appropriate limits defined by marine health. Using the model interface developed in this project, decision-makers and stakeholders can use the model to explore the temporal dynamics in marine activities under different governance scenarios. Although the model is limited to Algoa Bay, the model boundary can be adapted to assist in marine planning processes at national or trans-national scales. Such analytical assessments and tools are critical to progress the ecosystem-based management approach in MSP, as is required to achieve global sustainable development goals. , Thesis (PhD) -- Faculty of Science, Coastal and Marine Research Unit, 2021

Such analytical assessments and tools are critical to progress the ecosystem-based management approach in MSP, as is required to achieve global sustainable development goals. , Thesis (PhD) -- Faculty of Science, Coastal and Marine Research Unit, 2021
