  • Description: The overwhelming advancement of ICT devices in the contemporary Namibian education system has led to their praise for supporting differentiated instruction, fostering collaboration, and engaging multiple intelligences in teaching and learning. Consequently, the compulsory incorporation of ICTs into the teaching and learning process becomes imperative across various fields of study, including Mathematics. However, the integration of technology-based teaching proves to be a complex and challenging issue, often considered a wicked problem. To explore this matter, a qualitative case study was conducted to investigate how Senior Primary Mathematics Teachers integrated technology to develop their TPACK. The study was conducted among the twenty-seven senior primary mathematics teachers in the Okahao educational circuit in the Omuasti region. The study utilized Vygotsky‘s (1978); Socio-cultural Theory, together with Mishra and Koehler (2006), and; the Technological Pedagogical Content Knowledge (TPACK) framework was used as a lens to analyse the data. The data were gathered through semi-structured questionnaires, semi-structured interviews, focus group interviews, and lesson observations. The study findings indicate that senior primary mathematics teachers utilize the available resources at their respective schools during their classroom instruction. The study further reveals that mathematics teachers exhibit a positive attitude toward the integration of technology. The study uncovers the intricate interplay between technological knowledge, pedagogical expertise, and content knowledge within the context of mathematics education. The findings reveal that while participants demonstrate a high level of proficiency in certain TPACK components such as CK, TK, PK, TPK, and PCK, they expressed a moderate level of expertise in TCK and TPCK. The study also identified challenges in TPACK development, particularly the need for subject specific technology training, lack of technological infrastructure, particularly advanced technology, as well as a deficiency in ICT knowledge. The importance of access to various technologies was emphasized, enabling teachers to seamlessly integrate technology into their practices and address diverse learning styles. , Thesis (MEd) -- Faculty of Education, Secondary and Post-School Education, 2024

  • Description: Groundwater is a crucial component of freshwater supply globally, especially in water-scarce regions such as semi-arid climatic areas where surface water resources are climatically limited and further constrained during droughts. Groundwater resources are also important from an ecological perspective as they support numerous surface ecosystems including wetlands and rivers. Coastal groundwater discharge along the South African coast sustains supratidal spring-fed living microbialite ecosystems (SSLiME). These systems act as potential analogues for Earth’s earliest ecosystems and are therefore useful from a palaeoscientific and evolutionary perspective. The Southern Cape coast of South Africa is characterised by both fractured and intergranular aquifers and hosts the most extensive network of SSLiME reported globally. However, the region is frequently affected by water scarcity crises and consequently groundwater development and usage has increased. Yet, it is unclear to what extent coastal discharge is linked to inland aquifers and whether anthropogenic activities influence the quantity and quality of groundwater that flows into SSLiME. This thesis aims to assess the groundwater cycle of the Algoa Bay region along the Southern Cape coast by means of a multi-tracer study. Specifically, it endeavours to develop a better understanding of the hydrogeochemical connectivity between inland groundwater resources and coastal microbialite ecosystems. To achieve this, four groups of hydrochemical tracers were used: H- and O-isotope ratios, major cations and anions, organic micropollutants and macronutrients. Sampling strategies included monthly precipitation collection over twelve months (stable water isotopes), once-off groundwater collection from boreholes, inland springs and coastal discharge (all tracers). In addition, coastal groundwater discharge was sampled during a once-off repeat campaign (all tracers) and seasonally at selected sites (macronutrients). A local meteoric water line (LMWL) for the region was established and compared to the isotopic signature of groundwater. The results indicate that groundwater is likely recharged directly and with little evaporation. Furthermore, similarities in isotopic signatures between inland and coastal aquifer systems suggest some level of hydrogeological connectivity or similar environmental drivers of recharge, such as precipitation amount and moisture source. This is also supported by the physico-chemistry and major ionic composition of the groundwater samples. However, the major ion composition of groundwater is variable and, although it predominantly reflects the sodium-chloride nature of precipitation, lithological and spatial trends are apparent. For example, coastward trends such as increasing conductivity, calcium, total alkalinity, and nitrogen is evident. While isotopes and major ions inform on the environmental drivers and geogenic influence on groundwater recharge, the organic micropollutants and macronutrients provide insight into the nature of anthropogenic impacts on groundwater quality. Micropollutants quantified in the groundwater samples included artificial sweeteners, pharmaceuticals, a biocide, and an illicit drug. These compounds are mostly classed as wastewater indicators and indicate aquifer contamination from leaking reticulation systems and septic tanks. The highest concentrations are associated with the urban and coastal peri-urban areas, while groundwater from rural areas is often devoid of any micropollutants except sulfamic acid, which may be introduced during recharge from precipitation. Furthermore, the presence of selected compounds in groundwater discharge signifies that at least a component of the groundwater is derived from recent infiltration. Similarly, the macronutrient content of groundwater reflects the proximal land use. As such, coastal groundwater discharge sites adjacent to coastal villages reflect higher concentrations compared to rural sites. In addition, the nutrient load supplied to and discharged from SSLiME systems is quantified and the nutrient attenuation is estimated. This thesis contributes recent hydrogeochemical information for a structurally complex semi-arid area under both natural (drought conditions) and human (increased water use, degradation of aquifers) pressures. Collectively, the results indicate that coastal groundwater discharge is likely a mixture of both the intergranular and fractured aquifers and that anthropogenic activities in the hinterland is contaminating the groundwater. This study is an important addition to the baseline hydrological information available for the region and may be useful in terms of sustainable groundwater management strategies and development toward a socio-ecological optimum, especially as related to coastal microbialite system. , Thesis (PhD) -- Faculty of Science, School of Environmental Sciences, 2024

  • Description: Conservation planning has focused extensively on representation of species in protected areas (PAs), rather than achieving the persistence of these species in PAs. Consequently, most PAs do not support viable populations of many species represented within them, particularly large mammals, resulting in extinction debt risks. The challenge is therefore to identify opportunities to achieve viable populations and to develop and implement conservation plans to achieve this, e.g., expand and connect existing PAs. A recent meta-analysis provides a minimum viable population (MVP) estimate of 5 000 individuals for mammals. This value was used as the target for modelling conservation opportunities for the South African endemic Cape mountain zebra (Equus zebra zebra), blesbok (Damaliscus pygargus phillipsi), black wildebeest (Connochaetes gnou) and co-existing medium- and large-sized mammal species. This study focused on the region between the Camdeboo and Mountain Zebra national parks (ca. 736 000 ha). Within the envisaged Camdeboo-Mountain Zebra (C-MZ) mega-reserve, a spreadsheet model was used to estimate potential herbivore population sizes, spatial requirement data were used to estimate potential omnivore and insectivore population sizes, and herbivore densities were used to estimate potential large carnivore population sizes. I show that 12 (the three endemic grazers and nine co-existing species) of the 28 modelled medium- and large-sized mammal species will potentially exceed 5 000 individuals, the MVP target, within the envisaged mega-reserve. The remaining 16 species show potential to reach substantial population sizes, however, will likely require ongoing metapopulation management. Using a conservation planning approach, I identify priority areas for the conservation of suitable habitat for Cape mountain zebra, blesbok, and black wildebeest within the envisaged mega-reserve, thus indirectly identifying priority areas for the conservation of these endemic species. I show that the potential incorporation of these priority areas within the envisaged mega-reserve will contribute considerably to the conservation of all focal species. In addition, the potential incorporation of these priority areas will contribute to PA expansion and significantly improve connectivity between existing PAs within the envisaged C-MZ mega-reserve. The importance of adequately-sized PAs to support viable populations of focal species is thus evident, and will ensure their long-term survival and ability to persist by allowing population and evolutionary scale processes. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2024

  • Description: Understanding prey selection offers predictive insights into predator-prey interactions, which can be extended to explore the impacts of predators on prey populations. Prey availability and vulnerability vary across species, demographic classes, body sizes, and seasons. Traditional prey selection models for large carnivores, based on estimates of prey body size, assume uniform vulnerability across prey demographic classes and seasons, failing to account for these variations. This study aims to contrast seasonal shifts in demographic-specific prey preferences between lions and cheetahs and examine the potential impact of their demographic-specific predation patterns on a range of prey species across a body size spectrum. It was predicted that cheetahs would shift their selection from adults and juveniles of smaller prey species in the dry season to neonates and juveniles of both smaller and larger prey species in the wet season, while lions would select adults irrespective of the season. Additionally, predation focusing on adults would have a greater impact on prey populations compared to predation focusing on non-adults. Furthermore, it was predicted that prey populations experiencing demographic-specific selection from both lions and cheetahs would be impacted more than species selected by only one predator. Degrees of preference (DOP) were estimated based on prey availability (camera traps) and prey use (GPS clusters) for lion and cheetah populations in Lapalala Wilderness Reserve. Generalized Additive Models for Location, Scale, and Shape (GAMLSS) were used to determine seasonal shifts in demographic-specific prey preferences. The seasonal-demographic specific predation patterns of lion and cheetah, along with prey vital rates extracted from the literature, were then used to model potential predation impacts on prey populations using both Leslie-Usher and Lefkovitch matrix models. Lions preferred larger adult prey such as blue wildebeest, eland, and buffalo, while cheetahs preferred smaller prey, particularly juveniles of small to intermediate-sized species like impala, kudu, blue wildebeest, and zebra. Both predators showed seasonal shifts in demographic-specific prey preferences, with lions selecting adult buffalo during the dry season and juvenile buffalo in the wet season, and cheetahs selecting juveniles in the dry season and neonates and juveniles during the wet season. Lions and cheetahs exerted the highest degree of top-down limitations on their preferred prey. Predation on adult prey had a greater effect on prey population growth rates than predation on non-adults, especially in the dry season. Intermediate-sized prey species experienced the highest predation pressures, while larger prey species were more affected than smaller ones, contrary to the size-nested predation hypothesis. My study represents a first effort in the southern hemisphere to model the demographic impacts of multiple predators on diverse prey species, incorporating seasonal and demographic-specific prey preferences. The findings emphasise the importance of incorporating prey demographics and seasonality in predator-prey studies as these refined studies have implications for the management and conservation of both predator and prey populations. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2024

  • Description: This study aimed to generate an in-depth understanding of how the resolutions are being implemented post-mediation process and the labour union, which in this study is the National Union of Metalworkers of South Africa (NUMSA) and the mediator in the process of managing collective disputes between the employer and employee utilising mediation. The study was limited to the Volkswagen South Africa (VWSA) Kariega plant, therefore, the findings are contextually limited to the VWSA Kariega plant. The theoretical frameworks for this study were relative deprivation theory, frustration-aggression theory, Marxism, and dysfunctional and functional social conflict. These were utilised to explore and describe the phenomenon under investigation. This study employed a qualitative method to answer the research questions and address its problem statement. The data were collected through focus group discussions and elite interviews. The study used a purposive sampling technique, and the sample included 33 participants. The primary research question was: Were the agreements mediated at the VWSA Kariega plant effectively implemented between 1994 and 2021? The study’s findings imply that for the effective implementation of mediation resolutions, the following should be considered: implementing resolutions within the given timeframe, parties at mediation adapting and accommodating new technological changes and disasters at the National Bargaining Forum (NBF) level, prioritising the education and training of shop stewards and VWSA management representatives on NBF agreements, including the implementation thereof. Managing pertinent issues concerning NUMSA and the Automobile Manufacturers Employers Organisation (AMEO), interpreting NBF agreements, and ensuring that parties differentiate between the Labour Relations Act No. 66 of 1995 (LRA) and NBF processes. At the policy level, the findings imply that parties need to understand the LRA’s role and the process of resolving conflict utilising the formal processes stipulated in the LRA and why the LRA cannot override the NBF agreement as an informal process of managing conflict. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2024

  • Description: The study aimed to investigate the effectiveness of the Auditor-General’s findings in controlling public funds, with specific reference to the Bojanala Platinum District Municipality. The research is comprised of six chapters. The research adopted the qualitative research methodology approach. The study provides academic input into public administration, specifically for improving service delivery performance, control and financial performance management in municipalities. The study could contribute to the establishment of effective methods for monitoring municipalities’ control of public funds. The research also identified several strengths and weaknesses of the BPDM, which are vital for effective and efficient service delivery to the community. It is envisaged that other municipalities in South Africa will learn something from it. Furthermore, this research study envisages promoting the best control of public funds within the BPDM and improving the efficiency and effectiveness of service delivery to ensure communities’ well-being and dignity. Based on the findings primarily from the literature review and empirical survey, various recommendations are presented on how the existing status quo of the BPDM can be changed to enhance the better control of public funds, which can assist in service delivery and are aligned with the Batho Pele principles. If these recommendations are adopted, the BPDM will be able to deal with the developmental obstacles it currently faces more effectively and efficiently. , Thesis (MPA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2023

  • Description: The built environment in South Africa encounters the challenge of late payment. The issue of late payment has posed a major challenge to the service delivery efforts of government agencies. The delay in remunerating contractors adversely impacts their cash flow and impedes the expansion of their businesses. The construction industry is capital-demanding, and the timely payment of contractors by clients serves to mitigate cash flow challenges experienced by contractors. The main objective of the study was to gain a deeper understanding of the effects of governments late payments to building contractors in the Eastern Cape. The study therefore examined the experiences of building contractors in the Eastern Cape. The secondary objectives were to identify reasons for late payment and how it affects the cash flow of the contractor; to examine the implications of late payment and the effect it has on business growth; and to determine the reasons behind loss of productivity on site caused by late payment. The study was conducted within a quantitative research paradigm. The epistemological stance of the researcher was objectivist. The population for this study consists of building contractors based in the Eastern Cape Province registered with the Masters Builders Association (EC). A probability sample was used to identify the participants in this research. The data was collected using a survey as the primary research strategy. The survey findings suggest that many issues, including inadequate client finance, prolonged processing time for payment documentation, and non-standard payment methods, all lead to delayed payments to the contractor. The findings of the empirical study showed that, despite the lack of particular laws or regulations governing the construction industry’s payment systems, the sector nonetheless uses a number of common guidelines to guide payment practices. The pay-if-paid approach is associated with several limitations, since the contractor cannot always receive full payments as a result of incomplete or defective projects. , Thesis (MSc) -- Faculty of Engineering, the Built Environment and Technology, School of Built Environment and Civil Engineering, 2024

  • Description: Photobiomodulation (PBM) has gained a remarkable interest in the cosmeceutical industry, with research demonstrating supporting evidence for its use as anti-aging and skin-rejuvenating strategies. It is defined as photons at a non-thermal irradiance or non-ionizing photonic energy that trigger photochemical changes within the cellular structure to alter certain biological activities. Lasers were the main focus during the developmental years of light-based treatments, but since the introduction of non-ablative, light-emitting diode (LED) devices, the focus has changed because of the reduced concerns associated with lasers, such as costs, ablation cutting, thermally coagulating tissue, no downtime needed after treatment, and no trained staff needed for operation. The precise biochemical mechanism for PBM is still to be elucidated; however, accepted theories suggest that it has an influence on the activity of cytochrome c oxidase, a complex located in the electron transport chain, or on the viscosity of the interfacial water layer (IWL) of the mitochondrial membrane. The interaction of those cellular components with the light then leads to the primary responses of increased ROS, ATP production, and intracellular calcium, which ultimately leads to the stimulation of secondary responses that are desired for skin rejuvenation and anti-aging, such as cell proliferation and collagen production. There is controversy surrounding photobiomodulation (PBM), mostly because of the incomplete understanding behind its biochemical mechanism and the number of parameters that require optimization; however, it still poses as a promising field for research into anti-aging properties, as seen in the literature. Besides the use of devices for skin rejuvenation and anti-aging strategies, it is not uncommon to see plant extracts and other natural products being used in current skin care products for the same reason? This is mostly because of their promising bioactivities, some of which include antioxidant, anti-inflammatory, anti-bacterial, collagen-stimulating, and cell-proliferating activities. The aim of this study was to investigate the bio-stimulatory capacity of red light on skin cells and to evaluate possible effects it could have in combination with samples that already show promising anti-aging properties in research. The samples that were selected for this study are: Aspalathus linearis (rooibos) unfermented extract, L-ascorbic acid 2-phosphate, mangrove bee honey, stingless bee honey, Sargassum oligocystum (brown seaweed) and Ulva fasciata (green seaweed).It was found that red light irradiation did indeed stimulate the primary responses of ROS, ATP production, and intracellular calcium levels in HaCaT keratinocytes, as proposed in the hypothesised theory. However, none of the proposed secondary responses to cell proliferation or collagen production were demonstrated. In fact, the opposite was observed for cell proliferation and collagen production, where red light irradiation seemed to be cytostatic towards Hs27 fibroblast cells and caused significant decreases in collagen production. Red light energy dosages of 10, 20 and 30 J/cm2, yielded different primary responses with 20 and 30 J/cm2 generally causing more significant stimulation than that of 10 J/cm2. It should also be noted that even if the desired secondary responses were not observed in this study, it does not mean that red light does not have the capacity to still stimulate them. It is clear that the responses are energy dosage-dependent, and it is suggested that lower energy dosages could possibly lead to cell proliferation and that longer incubation periods post-irradiation are required before measuring the endpoint of collagen production. For the combination of red light irradiation and selected test samples, it was demonstrated that the order of samples that yielded the best outcomes is: stingless bee honey > mangrove bee honey > U. fasciata > S. oligocystum > 2-PAA > green rooibos. Unexpected results were demonstrated for green rooibos in the presence and absence of red light, which included decreased ATP production and collagen biosynthesis. Further investigation is therefore needed to have a better understanding of these unanticipated results. , Thesis (MSc) -- Faculty of Science, School of Biomolecular & Chemical Sciences, 2024

  • Description: In this work, wheel-and-axle compounds 1,4-phenylene-bis(diphenylmethanol) (H1), 1,4-phenylene-bis(di-p-tolylmethanol) (H2) and 1,4-phenylene-bis(di-p-fluorophenylmethanol) (H3) were investigated for their host behaviour in various pyridyl and heterocyclic guest mixtures. These host compounds were readily synthesized by means of Grignard addition reactions on dimethyl terephthalate, employing the aryl halides bromobenzene for H1 (73% yield), p-bromotoluene for H2 (69%) and p-bromofluorobenzene for H3 (70%). Molecular modelling calculations demonstrated that the various C-C-C angles differed between the computed low energy host conformers and those in the host molecules from their PYR-containing crystal structures. However, specified ‘torsion’ angles were in close agreement. Compound 1,4-phenylene-bis(diphenylmethanol) (H1) possessed the ability to form 1:2 host-guest (H:G) complexes with each of pyridine (PYR) and 2-, 3- and 4-methylpyridine (2MP, 3MP and 4MP). Furthermore, H1 showed preferential behaviour towards PYR and 4MP when presented with various mixtures of these four pyridines. Due to the high selectivity coefficients calculated in many instances (the selectivity coefficient, K, is a measure of the selectivity of a host compound for one particular guest in a mixture), it was demonstrated that H1 would be suitable for separations/purifications for many of the mixtures investigated in this work through host-guest chemistry strategies. (These pyridines are difficult to separate by means of the more conventional fractional distillations because of very similar boiling points.) Single crystal X-ray diffraction (SCXRD) analyses revealed that 4MP and 3MP experienced hydrogen bonds with the host molecule which were similar in distance, while the hydrogen bond distance between H1 and 4MP was shorter than that between H1 and 2MP. Furthermore, the hydrogen bond angles in complexes with the preferred PYR and 4MP guest species were more linear than in those having 2MP and 3MP. Additionally, preferred PYR and 4MP experienced significant π‧‧‧π contacts with nearby guest molecules, while disfavoured 2MP and 3MP did not interact in this fashion. Hirshfeld surface analyses demonstrated that PYR and 4MP (favoured) were involved in a greater percentage of (guest)N‧‧H(host) , Thesis (MSc) -- Faculty of Science, School of Biomolecular & Chemical Sciences, 2024

  • Description: Since the start of the Yemeni conflict in 2014, both the Saudi-led military and the Iranian-backed Houthi Rebel group have launched missile airstrikes across the nation (Sharp & Brudnick, 2015). These attacks are carried out using high-tech military tools, such as drones, aircraft, bombs, and other weapons. According to Hokayem (2016), nearly 24 million Yemenis require aid as Yemen experiences the world’s largest humanitarian crises. Open Secretes released a report in 2020 outlining that weapons used in the war in Yemen could be traced back to Denel, alluding to its role and complicity in the conflict. The aim of this study is to investigate the role of Denel in the conflict in Yemen and its socio-economic effects. In doing so, South Africa’s trade relations with the Saudi-Arabia will be explored. In addition, unpacking the socio-economic conditions that exists domestically and internationally that influence global arms trade. A qualitative research approach is employed. Secondary research analysis is conducted using government publications, international policy reports, books, journals, and newspaper articles. In addressing the social aspect of the arms trade effects, the humanitarian component uses a psycho-social theoretical framework which encompasses Burtons’ human needs theory. In addition to this main theory, the frustration-aggression theory as well as the relative deprivation theory were applied to support the theory central to the study. Fundamental to this study is understanding Denel’s’ complicity in the conflict in Yemen and the effects thereof. This stems from the company’s trade agreements between itself and Saudi Arabia, which has been at the forefront of multiple proxy wars within the region. Denel’s implied complicity stems from the correlation between the heightened period of conflict in the Yemen and the parastatal’s record-breaking order book during the same period. The research study focuses on the period between 2013 – 2016. Further research has been conducted in order to provide a comprehensive historical account and context of the conflict and the role of Denel as a parastatal organisation. Furthermore, this study delves into ongoing crises and the volatile nature of global arms trade regulations. It is for the reasons alluded to above that the study insists on not limiting period of the study to 2013 – 2016. The study findings suggest that although weapons used in the conflict in Yemen could be traced back to Denel, these were insignificant to the overall contribution to the conflict in Yemen, despite South Africa’s and Saudi Arabia’s breach of the End-User agreement. As a result of Saudi Arabia’s continued infringement of human rights, the state was not to be sold weapons as they are proven to have further ramifications against the protection of human rights. Moreover, the arms trade industry partially functions independently from government intervention and regulation, making it increasingly difficult to implement international policy. What is of paramount importance is the direct effect of conflict on innocent civilians who continue to suffer and the human cost of profit and the struggle for power and resources. Recommendations highlighted in the treatise include striking a balance between profitability and the humanitarian perspective by taking into consideration both private sector profit motives and the public sector's responsibility to prioritise human rights and the well-being of people. This approach ensures efficient management of Denel and reduces the possibility of privatization, as Denel remains the lifeline of the South African Defense Force (SADF). To ensure compliance with domestic and international arms treaty regulations, it is necessary to enforce a stricter process for arms sales justification. The agreement should incorporate legal measures that enable the prosecution of the state in cases where irregularities in weapons sales approval, including corruption or personal/political motives, are identified. The study recommends that Denel should initiate a strategic restructuring plan to revitalise its business model and leadership development. This restructuring should prioritise ethical business practices, legality, and vetting of customer information while ensuring profitability for self-sustainability. Addressing irregular sale agreements is crucial before investing in technology advancement and research. Growth assessment should be based on profit margins and order book prospects to ensure business optimisation and resource adequacy. Denel's success is vital for South Africa's GDP growth. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2024

  • Description: The concept of pharmacists as key providers of pharmaceutical services with supporting personnel is quite uniform across the world with differences in the requirements for the registration, scope of practice, and training approach. Pharmacy support personnel have been part of the workforce for many decades in South Africa, practicing in all pharmacy categories. Pharmacy support personnel are required to undergo training in the category in which they are employed and registered. There is limited literature on the scope of practice and training of pharmacy support personnel in pharmaceutical manufacturing. This research project was undertaken to determine the perceptions of pharmacists’ assistants (post-basic) in Gauteng on the appropriateness of the training received to their roles in pharmaceutical manufacturing. A descriptive qualitative design was employed for the study which involved pharmacists’ assistants (post-basic) who were trained and employed in pharmaceutical manufacturing. Semi-structured virtual interviews were conducted with the participants to gain their understanding regarding their experiences and perceptions of the training they received. The perception of participants on whether the training prepared them to their role was interpreted through thematic analysis. Pharmacists’ assistants (post-basic) perceptions regarding the training they have received to support their roles was generally positive, with an emphasis on the comprehensiveness and appropriateness of training. Participants supported their perceptions by providing scenarios in their workplace on how the training has improved their knowledge in performing their job functions and confidence in carrying out their duties. Differences in perceptions regarding preparedness of PAPBs to carry out their roles and responsibilities in pharmaceutical manufacturing were noted and appeared to be dependent on the nature of the role and the activities involved where further on-the-job training might be required. Participants also demonstrated an interest in the expansion of the curriculum to cover more specialised other aspects of the pharmaceutical manufacturing such as quality and regulatory. Participants perceived the education and training to prepare them for the roles and responsibilities in pharmaceutical manufacturing and recommendations for future research studies on training programmes and job functions for PSP were identified. , Thesis (MPharm) -- Faculty of Health Science, School of Clinical Care and Medicinal Sciences, 2024

  • Description: The position of workers and trade unions has changed drastically since the introduction of a Constitutional dispensation in South Africa. The Constitution affords both workers and trade unions protectable rights and greater influence at the workplace. To vindicate and assert these rights trade unions and workers approach the courts to vindicate these rights. Section 23 of the Constitution deals with labour rights and section 18 gives effect to the right to freedom of association. To give content to these rights the Constitution provides that courts must have regard to international law. In the context of these rights, one of the principles recognised by the International Labour Organisation through its Conventions is the principle of majoritarianism. In short, the principle endeavours to give effect to the will of trade unions representing the majority of employees in a workplace in relation to trade unions that represent the minority. This is achieved through collective bargaining, which typically results in the conclusion of collective agreements, whereby trade unions are given exclusive and or preferential rights. In AMCU v Royal Bafokeng the Constitutional Court held that, the principle of majoritarianism applies to and finds expression in section 189 of the Labour Relations Act. The effect of this judgment is that members of a minority trade union may be represented by a rival majority trade union during the consultation process when an employer has contemplated dismissals based on operational requirements. The minority judgement adopted a different approach, reasoning that, the principle of majoritarianism ought not to find application in the context of dismissals based on operational requirements. It found that section 189 is intended to give effect to the Constitutional right to fair labour practices and must therefore allow a fair procedure that permits an employee to choose who may represent him/her in a consultation process prior to dismissal. , Thesis (LLM) -- Faculty of Law, Department of Mercantile law, 2024

  • Description: Schistosomiasis, often known as bilharzia, is a parasitic water-borne disease caused by trematode flatworms of the genus Schistosoma. In 76 endemic countries, including 46 in Africa, over 800 million individuals are at risk of contracting the disease. This study examined the influence of water physicochemical properties, vegetation type and community knowledge, attitudes and practices (KAP) on the distribution and habitat preference of schistosomiasis intermediate host snails in the communities of Kariega and Kwa Nobuhle, in Nelson Mandela Bay. Methods. A quantitative cross-sectional research design approach was employed in this study. Data for the water physicochemical properties was collected over different seasons over a 9-month period. Eight sampling sites were selected based on their proximity to residential areas. A simple dip method was used for surface water samples and measurements done using a Bante 900P multiparameter meter, Macherey Nagel PF-12 plus, and hardness meter. A 300 μm mesh scoop net on a metal frame was used to capture snails. At each sample site, the predominant plant species were gathered and transported to experts in the Botany Department at Nelson Mandela University for identification. The composition and percentage cover of vegetation were visually estimated and documented. A structured questionnaire was used to elicit responses from 380 participants for the pre- and post-intervention KAP study, using the interview format. Data was analysed using R software (version 4.3.1) and Microsoft Office 365 Excel (2019 version). Results. Freshwater snails were found in all eight water bodies studied; however, schistosomiasis intermediate host snails were only found in three of them while the prevailing species in the study sites were Physa snails. There was no correlation between the number of snails and turbidity (r=-0.070). However, a negative and weak correlation existed between snails and DO (r=-0.185), hardness (r=-0.210), pH (r=-0.235), TDS (r=-0.236), EC (r=-0.240), salinity (r=-0.242), and temperature (r=-0.273). There was also a negative correlation between snails and vegetation coverage (r=-0.127). Of the 380 study participants, only 8.7% were aware of the disease pre-intervention. The paired samples t-test results demonstrate a difference (7.2 ± 2.5) in knowledge scores, and the improvement in knowledge levels post-intervention is statistically significant (p<0.001). Conclusion. The study discovered an abundance of Physa snails; considering their biological characteristics and ability to endure, these snails could potentially serve as a biological control agent in locations where the , Thesis (MSc) -- Faculty of Health Sciences, School of Behavioural & Lifestyle Sciences, 2024

  • Description: This study is aimed at determining the role that hashtag activism has played in advocating against gender-based violence (GBV) and promoting perpetrator accountability. The study used major GBV hashtags such as #MeToo, #WhyIStayed and #AmINext to investigate how effective these hashtag movements have been in breaking the silence around GBV and fighting against GBV. The study made use of both qualitative and quantitative research methodology, which was useful to gain a deeper understanding of GBV and all the social and cultural practices that perpetuate it. Qualitative data were collected by means of interviews and tweets under the selected hashtags. An online survey questionnaire was used to collect quantitative data. The data provided an understanding of the complexities surrounding GBV and people’s views on hashtag activism and GBV. Through the data analysis, the study found that hashtag activism has been effective in changing dominant discourses, advocating against GBV, creating awareness and solidarity around GBV issues, and promoting perpetrator accountability. The study calls for a global collective effort to develop, record and archive feminist initiatives so that all the structural conditions which enable and perpetuate sexual violence are exposed and cannot be forgotten or ignored. Future research should look into how harmful societal norms can be challenged and how the effectiveness of hashtag movements can be enhanced , Thesis (MA) -- Faculty of Humanities, School of Language, Media and Communication, 2024

  • Description: This study investigates the intricate dynamics of music within the umgidi initiation ceremonies among the amaMpondo, focusing on the interplay between traditional and modern popular music. The study explores the cultural foundation of the umgidi ceremony, emphasising its transformative significance and the evolving influence of modern popular music, particularly among the youth. A comprehensive literature review follows, contextualising the amaMpondo, their cultural practices, and the complex relationship between traditional and popular music in the broader South African music scene. The study adopted a qualitative ethnographic approach, including participant observation and individual interviews, to explore the impact of modern popular music on traditional elements during umgidi initiation ceremonies. Thematic analysis was employed for data interpretation, ensuring a systematic exploration of patterns and meanings. Ethical considerations were meticulously addressed, emphasising protecting participants' rights and cultural sensitivity. The study's findings highlighted the multifaceted roles of music during umgidi initiation ceremonies. Music is a powerful medium for cultural expression, communication, and communal celebration. The call-and-response format, rhythm variations, and the influence of modern genres such as Gqom and Amapiano were explored. Community attitudes toward integrating modern popular music reveal diverse opinions, ranging from full embrace to resistance. In summary, this study contributes to understanding the evolving dynamics of music in umgidi initiation ceremonies among the amaMpondo. The study provides a nuanced exploration and a roadmap for future research, community engagement, and policy considerations by combining cultural insights, literature review, methodological rigour, and community perspectives. , Thesis (MMus) -- Faculty of Humanities, School of Visual and Performing Arts, 2023

  • Description: As the landscape of higher education undergoes a shift toward a combination of online instructional methods and traditional in-person engagement, a creative approach becomes essential in ensuring student success. The research aims to explore how visual storytelling can enhance the online learning experience at Nelson Mandela University (NMU), thereby improving the effectiveness of teaching and knowledge acquisition. This study delves into the Learning Experience Design (LXD), a blend of instructional design, design thinking, and user experience design, within the teaching community of Nelson Mandela University and the broader South African context. Employing a mixed-method approach, qualitative data from interviews identified themes such as the improvement of LXD, challenges in the design process, and the utilization of visual storytelling. Quantitative analysis revealed that students primarily used the university learning management system (Moodle) for accessing resources, grades, and reviewing tests, with limited engagement in online learning activities. Lecturers expressed concern about Moodle’s functionality, a need for enhanced design support, and the necessity for training in the transition to digital learning. While lecturers recognized the potential of visual storytelling in enhancing engagement and knowledge retention, they emphasized the importance of support for the seamless integration into teaching. Students acknowledged the positive role of visual storytelling in improving their learning experience but highlighted areas of improvement, such as regular updates, increased visual interaction options, and the inclusion of information graphics to explain concepts. A design thinking process informed the development of instructional design interventions, leading to the creation of a prototype Moodle course shell and resources. This initiative aims to empower lecturers to enhance the learning experiences independently with the support of professional LXD services. The research findings suggest that visual storytelling indeed improves LXD, emphasizing the need for established support systems and resources at the university to equip lecturers for successful integration. , Thesis (MA) -- Faculty of Humanities, School of Visual and Performing Arts, 2024

  • Description: A foreign company providing services in South Africa may, depending on the nature of the services rendered, do so directly or through its branch. Where the foreign company or its branch in providing such services falls within the ambit of the compulsory registration requirements set out in section 23, the foreign company or its branch is obliged to register as a vendor and the provisions of the VAT Act thereafter apply to such foreign company or its branch. The nature of the services rendered determine whether it is the foreign company or its branch which is obliged to register as a vendor. Where the services rendered constitute 'electronic services' falling within the scope of paragraph (vi) of the enterprise definition, it is the foreign company which must register as a vendor and not its branch. In all other cases (apart from the supply of 'imported services'), where services are rendered in South Africa, it is the branch which must register as a vendor, unless it is a 'dependent agent' of the foreign company as envisaged in the Wenco case 1, in the sense that it has no clients of its own in South Africa and supplies only services on behalf of the foreign company. In such a case the branch does not conduct an 'enterprise' and its foreign company must register as a vendor. Where a dependent branch supplies services to the foreign company's main business abroad, the supply is not zero-rated in terms of section 11 (2)(o) as, on the authority of the Wenco case, the provisions of section 8(9) have no application in such a case. Generally, where a foreign company or its branch supplies services in South Africa and is obliged to register as a vendor, output tax is levied in terms of section 7(1 )(a) and an input tax deduction may, in certain circumstances, be claimed provided that the foreign company or its branch is actually registered for VAT. In the case of 'imported services' it is the recipient which is liable for VAT thereon in certain circumstances. , Thesis (LLM) -- Faculty of Law, 2024

  • Description: It is understood that, for us humans to communicate with one another, we need language. Communication thus has a close relationship with society. But language changes and it has many varieties. On the one hand we have the standard variety of a language which is mostly used in formal situations, and on the other hand we have other varieties, which are mostly used in informal situations. Slang serves as an example of the latter and is chiefly used by adolescents – individuals between the ages of 13 and 19. As Saal and Lawrence (2019: 24) put it: young people are the agents of linguistic change. The researcher finds the language of teenagers quite interesting seeing that he is a teacher who frequently comes across words or phrases he has not heard or does not know the meaning of. The goal of this study is thus to investigate teenage language as phenomenon, with special reference to slang. This study examines slang words and expressions as they occur among teenagers in two Nxuba (formerly Cradock) schools, as well as find out why, when, and when the research group will not make use of slang. Nxuba forms part of the Inxuba Yethemba Municipality in the Eastern Cape. During the study general linguistic phenomena that occur among the teenagers in the given town are also investigated. These phenomena are analysed using the phonetic, phonological, morphological, syntactic, semantic, and lexical levels of variation. This study follows a qualitative approach with the help of questionnaires, direct observation, and focus group interviews as data collection methods. It was found that teenagers are highly creative and create novel words or give new meanings to words that already exist in the standard variety. The reasons why teenagers make use of slang is, among other things, to ease communication, for the fun of it, secrecy, and to enrich the standard variety. Slang is mostly used in informal situations and tends to be avoided in the presence of older persons, at church, and when doing schoolwork. There are also various linguistic phenomena that appear in teenagers’ general language usage: borrowing, reduction, homonyms, polysemes, and various phonological phenomena, among other. , Thesis (MA) -- Faculty of Humanities , School of Language, Media and Communication , 2024

  • Description: There have been numerous claims regarding how quality management systems facilitate the implementation of Total Quality Management (TQM) among Government Implementing Agents, particularly within the Eastern Cape Department of Public Works and Infrastructure. However, the success rate of TQM implementation in ECDPW projects varies. This study aims to investigate the implementation of TQM within these construction projects. Additionally, five secondary objectives were established to further this investigation. Utilizing a quantitative research approach, data obtained from a semi-structured questionnaire survey was analyzed. The analysis was based on responses from 44 out of 50 questionnaires distributed. Implications: The practical implication of this study lies in identifying the implementation of TQM among Governmental Implementing Agents, particularly within the Eastern Cape Department of Public Works, and understanding the challenges they encounter. The theoretical implications encompass contributing to existing studies that validate quality comprehensively within ECDPW construction projects and suggesting ways they can effectively implement TQM across their processes. The research findings confirmed the challenges and difficulties experienced during the various phases—pre-construction, construction, and post-construction—of projects managed by the Eastern Cape’s Department of Public Works. It was evident that Total Quality Management lacks robust implementation within ECDPW construction projects, directly impacting project quality and the effective execution of quality management systems. A key limitation of this study is the absence of data collection on the professional backgrounds and years of experience of the study participants. During pilot testing, it was found more suitable to identify job roles rather than professional backgrounds. , Thesis (MSc) -- Faculty of Engineering, the Built Environment and Technology, School of Built Environment and Civil Engineering, 2024

  • Description: This study explores sociolinguistic practices such as translanguaging, in which “diglossia is presumably allowed without isolation and bilinguals’ linguistic resources are viewed as an integrated system.” While bilinguals select and deploy particular features from their linguistic repertoires for meaning-making, translanguaging is widely used by teachers and students in multilingual classroom settings, as guided by the Personnel Administrative Measures (PAM). Translanguaging also provides a path for students to bring in and use their linguistic repertoires to produce the required learning outcomes, perform their identities and facilitate language development. Thus, this study is based on the view, subscribed to in contemporary sociolinguistics, that monoglossic language ideology is embedded in modes of oppression steeped in neoliberal, colonial and linguistic purist forms”. The purpose of the study was to make a case for the implementation of translanguaging in the written assessment of isiXhosa/English bilingual high-school learners in the Eastern Cape. The study employed a qualitative approach in the form of document analysis, whereby the researcher used selected Grade 12 question papers to find out how often translanguaging occurred. This was done by illustrating how examiners are moving past forms of linguistic purism when setting papers. , Thesis (MA) -- Faculty of Humanities, School of Language, Media and Communication, 2024
