  • Description: The study set out to critically analyse the criteria used by South Africa to determine the distinction between independent contractors and employees. Comparisons are also drawn with the criteria used in the United Kingdom(UK) and New Zealand (NZ) to assess whether there are new ideas that can be drawn from these and help improve the criteria used in South Africa. This was motivated by the ongoing debates around this issue and the desire to make a contribution that might bring some new insights and clarity. Under South African tax legislation employers are only obliged to deduct income tax from persons identified as employees while on the other hand, they cannot deduct tax contributions from the money paid to independent contractors for services rendered. Furthermore, there is no statutory definition for the term “independent contractor” in the Income Tax Act of South Africa nor in the country’s labour legislation. The definition of this term has largely been established by the labour courts in instances where disputes have arisen around these matters. Using a doctrinal research method (including a comparative legal research), which is a qualitative research approach, articles, statutes, judgements, explanatory memoranda, and policy documents on the subject under investigation were analysed. It is submitted that the criteria used in the two countries used in the comparison are similar to the ones used in South Africa, with some variations. All three countries use similar tests to make their determinations and a survey of the UK and NZ’s case law indicates that the most preferred criteria are the multifactoral approach to determine the true nature of the relationship between employers and their employees. This approach has been found to be more flexible which allows it to accommodate the changes that are occurring in the world of work. In the South African context, the labour court has adopted a substance-over-form approach in making their determinations, arguing that the nature of the working relationship between employer and employee is a more important indicator than the mere contents of a written contract. The labour court has also used labour legislation mainly to assist in the interpretation of the distinction between independent contractors and employees. The study established that the criteria used in the UK is a bit more complex because workers are put in three different categories and the definition of employee is not 4 uniform in all the available statutes. In New Zealand the multiple factor approach is preferred just like in South Africa. In conclusion is submitted that the study established that there is nothing, other than the UK’s Mutuality of Obligation Test, that would assist in further clarifying the criteria used to classify employees or independent contractors in South Africa , Thesis (MA) -- Faculty of Faculty of Business and Economic Sciences, 2023

  • Description: Globally incidents of fraud are on the increase, resulting in an expectation from users of internal audit services that internal auditors should accept responsibility for conducting fraud investigations. This expectation exists even though limited guidance pronouncements on how to conduct fraud investigations being available from the Institute of internal auditors (IIA) and internal auditors not always being equipped to conduct fraud investigations. This expectation also stretches beyond the current pronounced role and responsibilities of internal audit practitioners, according to the IIAs International Professional Practices Framework (IPPF) (hereafter, referred to as the Standards). Conducting fraud investigations without possessing the relevant knowledge and skills, introduces the risk that evidence collected may be considered inadmissible in a court of law. The research problem is stated as, “a dearth of adequate guidance pronouncements for internal audit practitioners exists, in respect of fraud investigations.” In response to the expectation, risk, and research problem, underpinned by the policeman theory and theory of inspired confidence, the primary research objective of the study was to develop a fraud investigation proficiency self-assessment framework for use by internal audit practitioners who are expected to conduct fraud investigations. The study’s research objectives were achieved by making use of an interpretivist research paradigm and a qualitative methodological approach. Data were collected through semi-structured interviews from authoritative internal auditors on the membership database of the Institute of Internal Auditors South Africa (IIASA). Findings confirmed the existence of an expectation gap and the lack of guidance contained in IIA guidance pronouncements and Standards. Developed from the findings, the thesis proposes a fraud investigation proficiency self-assessment framework. The proposed self-assessment framework lists 14 fraud investigation knowledge and skills measures in the form of statements that internal audit practitioners should use to assess their personal level of proficiency for conducting a fraud investigation. The results from the self-assessment should then be Page | vii used to guide an internal audit practitioner on whether to accept the responsibility for conducting a fraud investigation or to defer the investigation to a more proficient fraud investigator. The decision for accepting the responsibility to conduct a fraud investigation ultimately resides with the internal audit practitioner. The study concluded that an expectation from organisations exists for internal audit practitioners to conduct fraud investigations, even though limited guidance pronouncements are available to internal audit practitioners from the IIA for conducting fraud investigations. The study identified that the most prominent risk associated with a fraud investigation being conducted by a person lacking the required fraud investigation knowledge and skills was that of collected evidence being dismissed in a court of law and not being able to use the evidence against a perpetrator. It can, therefore, be recommended that internal audit practitioners should not conduct a fraud investigation if they lacked any of the proficiencies required. The study provides support for the development and use of the proposed fraud investigation proficiency self-assessment framework. , Thesis (PhD) -- Faculty of Faculty of Business and Economic Sciences, 2023

  • Description: The globally applied six-step financial planning process which is used by CFP® professionals to provide financial advice is designed to ensure that the financial advice is suitable, based on the needs of the consumer. However, given the diverse cultures in South Africa, this study argues that the six-step financial planning process (as it is currently applied) may not be suitable, as it requires contextualisation based on the unique needs of South African consumers. The various population groups in South Africa have their own sets of beliefs, values and cultural practices, and thus view aspects such as wealth (the creation, preservation and transference thereof), marriage, death and retirement, differently. Thus, financial planners who are not knowledgeable about different cultures, diverse financial needs, or the provisions of customary law, may not be able to provide suitable advice. The primary objective of the study is thus to reconceptualise the six-step financial planning process to be more inclusive, in order to better serve the financial planning needs of South African consumers. A comprehensive literature review was undertaken to provide the context and framework within which the reconceptualisation of the six-step financial planning process could be approached. An investigation of the financial planning environment and the financial planning process was completed to determine how the six-step financial planning process is currently applied in the South African context. Further, an investigation of culture and the cultural dimensions – power distance, uncertainty avoidance, individualism, masculinity, timeorientation and indulgence – was conducted, as it was clear that these cultural dimensions cannot be generalised to all South African consumers, due to the large degree of diversity within the population. It was also determined that there are various factors that contribute towards the cultural diversity of South African consumers, which may influence their financial needs and the type of financial advice that is required. These factors include race and ethnicity, marital regimes, procreation and family structures. To further illustrate the diversity of financial needs of South African consumers, a discussion of Black households and the application of financial planning legislation and customary law was provided. Black households are considered to be under-serviced, historically financially excluded, have low levels of financial literacy, and are mostly collectivist in nature. It is for these reasons that Black households are the focus of the study. Some of the financial needs that vi are common among Black households include land and property ownership, family wealth, family homesteads, lobola capital and ‘black tax’ expenditure. Given that the literature review established how the six-step financial planning process is currently applied, an interpretivist research philosophy was adopted in order to gain a deeper understanding of how the six-step financial planning process should be applied in a South African context. Further, the research approach in the context of this study is an inductive one, as the six-step financial planning process is an existing theory that was reconceptualised by considering the perceptions and experiences of 16 CFP® professionals and 14 Black South African households. A mono-method qualitative research methodology was used, with a single qualitative method of data collection (semi-structured interviews), and a single qualitative method of data analysis (latent content analysis). The findings of the study were used to provide a reconceptualised perspective of the six-step financial planning process which takes into consideration the fact that the image of a financial planner plays an important role when trying to establish a professional relationship with a client. The findings reveal that Black consumers in particular, generally have a negative image of a financial planner, which is influenced not only by their perceptions of a financial planner, but also by their self-perception of their own financial situation. The reconceptualised perspective of the six-step financial planning process also incorporates the finding that discussions around personal finances are considered impolite and taboo among the Black African community, which influences their ability to talk about these topics, trust a financial planner, and establish a professional relationship with them. The findings also reveal that a racial and gender bias exists among Black consumers – they prefer interacting with a White male financial planner, as they perceive them to be more competent and have more experience with finances and wealth accumulation. It was also found that CFP® professionals believe that having cultural awareness and cultural intelligence can reduce bias in the way that questions are asked, so as not to offend the client. Thus, cultural awareness was also incorporated into the reconceptualised perspective of the six-step financial planning process. It was also noted that it is important to ascertain clients’ level of financial literacy during the information gathering stage. Black consumers opined that in this regard, it is the role of the financial planner to both ascertain and ensure their clients’ financial literacy, and to offer financial education to ensure client understanding. vii Although the premise of the study is that South African consumers have unique financial needs due to the high degree of diversity among the population, it was the opinion of CFP® professionals that Black consumers, in particular, do not have unique financial needs – instead, they define their needs differently, have different exposures to financial resources to address their financial needs, and also prioritise and satisfy their needs differently. The prioritised financial needs of Black households (sub-themes) that emerged from both participant groups include the need to make provision for black tax, estate planning, funerals, and property ownership. Black household participants mentioned (to a greater extent than CFP® professionals did) the need to make provision for lobola and initiation schools, as these form part of several traditional ceremonies. The need to make provision for a family home was mentioned by Black household participants but not by CFP® professionals. It was discovered from Black household participants that stokvels are the most common micro-finance tool used by Black consumers, for various reasons. In fact for some, stokvels are preferred over formal financial products because they perceive that they yield a higher return, and others use them successfully to supplement their current provisions. These findings (among others) were incorporated into the reconceptualised perspective of the six-step financial planning process which is presented in this study. This study has made a contribution to the financial planning body of knowledge by presenting a reconceptualised perspective of the six-step financial planning process, and providing new knowledge on each of the associated six steps and their suitability in a South African context. This study also provides justification and evidence for the inclusion of aspects within the sixstep financial planning process that enhance the understanding of cultural diversity and needs of Black households in particular. Justification has also been provided for the inclusion of cultural aspects and diverse needs of Black consumers the in the academic curriculum of FPI and FSCA recognised qualifications, as well as the facilitation and learning outcomes of business and product-specific training that FSPs are required to provide to their representatives. The study findings also have implications for the development of the academic curriculum and assessment materials for CFP® professionals by recognised education providers, the FSCA regulatory examination, and the FPI professional competency examination. In addition, the study has provided evidence for the need to develop financial products, or customise existing financial products, that address the viii needs of Black households – especially culture-specific financial needs such as black tax, lobola and funding for initiation schools. Key words: Black households; CFP® professionals; culture; diverse needs; reconceptualisation; six-step financial planning process. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

  • Description: The platinum group metals (PGM) mining sector is the largest component of the South African mining sector based on its contribution to GDP, employment and its overall contribution to the South African economy. Over the past decades South African production of PGMs has been declining, but post global financial crisis the country’s production growth has reduced due to the significant labour disruptions the industry has faced since late 2010. This paper aims to analyse the impact of these industrial strikes on the South African economy for the period 1 January 2008 to 31 December 2016 given the availability of data and significant strikes in that period. An examination of the impact strikes has had on the South African economy by running regressions using the generalized autoregressive conditional heteroskedasticity (GARCH) technique. The study also looked at economic variables such as exchange rate, interest rate and the platinum index to determine the effect on the platinum mining sector. Regression equations are tested to prove the effects strikes have on theses variables and the economy at large , Thesis (MA) -- Faculty of Faculty of Business and Economic Sciences, 2023

  • Description: Africa has the highest Human Immunodeficiency Virus (HIV) prevalence in the world and has invested heavily in running its HIV programmes and conducting research of medical significance. Despite efforts in combating this disease the production, distribution, cost, and availability of antiretroviral (ARV) generics remains a major problem as they are imported from China and India. Exploring the recently emerged “enabling technique”, namely flow chemistry in the production of APIs has gained a lot of attention. This study was devoted on exploring the application of flow chemistry on the synthesis of a newly approved anti-HIV drug dolutegravir (DTG); an integrase inhibitor with a high genetic barrier to resistance with a daily dosing scheduled compared to other ARVs and its third-generation inhibitor analogue, cabotegravir. Chapter one covers a comprehensive background and literature review of the HIV epidemic, an introduction of antiretroviral therapy as well as detailed dolutegravir and cabotegravir synthesis. A brief introduction of continuous flow technology with its advantages and disadvantages is discussed in this chapter. The efficient seven-step continuous flow procedure afforded dolutegravir and cabotegravir in improved reaction times and yields compared to the traditional batch procedure was demonstrated. The significant advantage of this flow process includes the reduction of the overall reaction time from step one to step seven, from prolonged 68 hours in batch to 34 minutes. The overall yield of each reaction step improved dramatically upon flow optimization. The yields of the second step (selective ester hydrolysis), fourth step (cyclization) and fifth step (amidation) increased from 64 %, 40 % and 33 % in batch to 98 %, 71 % and 100 % yield by HPLC respectively. Other than improved yields and residence times which was aided advantages of microreactor technology including intensive mixing, the flow process is also much better because it is cost effective. Most importantly, a novel process on the formation of pyridinone intermediate using ion-exchange resin catalysts towards the synthesis of dolutegravir and cabotegravir was described in this study , Thesis (PhD) -- Faculty of Science, School of Biomolecular and Chemical Science, 2023

  • Description: Habitat degradation, livestock farming, crop cultivation, rangeland overutilization and veld mismanagement are among the factors causing biodiversity loss worldwide. Rangelands in arid and semi-arid environments are no exception, as they are under stress from conversion into cropland and pressure from livestock farming. In these arid areas, rainfall is unpredictable and plant recruitment levels low, resulting in veld rehabilitation being a potentially expensive and time-consuming undertaking for landowners. Landowners implement different rehabilitation methods to increase overall vegetation cover and prevent further soil and vegetation degradation. These rehabilitation methods may include the creation of micro-catchments, mulching, brushpacking, ripping, geotextiles, stone cobbling and erosion control fences, individually or in combination with the addition of reseeding, replanting, and use of manure or fertilizer to supplement land rehabilitation. This study investigated the significance of three rehabilitation methods (hollows, brush packing and a combination of these two methods) on water infiltration rates, soil moisture content, and vegetation canopy cover with associated growth form canopy cover over a period of 17 months (March 2021 to August 2022). This study showed that rehabilitation methods implemented had no significant impact on water infiltration rates and vegetation canopy cover. However, rehabilitation methods had a significant impact on soil moisture content. The use of a hollows is recommended when attempting to increase the soil moisture content percentage when performing rehabilitation. Overall vegetation canopy cover is influenced more by seasonal changes than by the rehabilitation methods implemented. This study indicated that the creation of micro-catchments is an effective rehabilitation method to use in an arid area, as it promotes vegetation establishment and growth. , Thesis (MSc) -- Faculty of Science, School of Natural Resource Science and Management , 2023

  • Description: Counterfactual impact evaluation studies form an important evidence base for the effectiveness of conservation projects, programs, and policies (collectively referred to as conservation interventions). In South Africa, counterfactual impact evaluation methods have rarely been applied to local conservation interventions, and therefore evidence for the effectiveness of key strategic national conservation approaches is lacking. This study evaluated three area-based interventions that together aim to avoid the loss of areas most important for the persistence of biodiversity in the terrestrial realm as evidence towards the effectiveness of South Africa’s landscape approach to biodiversity conservation. The first intervention, South Africa’s National Protected Area Expansion Strategy (NPAES), set ambitious targets to double the extent of South Africa’s protected area network while ensuring that the expansion preferentially occurs in areas of under-represented biodiversity. The strategy was evaluated in terms of its effectiveness in guiding protected area expansion towards more equitable representation of South Africa’s biodiversity through an assessment of changes in indicators of protected area expansion decision-making before and after the implementation of the strategy. The second intervention is the use of maps of biodiversity priorities to guide land use change decisions outside protected areas. Impact was evaluated as avoided loss of Critical Biodiversity Areas (CBAs), which need to remain in a natural condition to meet in situ conservation targets for species, ecosystems, and ecological processes. Avoided loss in CBAs was benchmarked against avoided loss in protected areas, to contextualize the effectiveness of land use planning as a conservation intervention. Lastly, the effectiveness of stricter land use regulations for threatened ecosystems to reduce land conversion pressure on these ecosystems was evaluated. Key findings were that protected areas are highly effective conservation interventions where they can be implemented, but their capacity for conservation impact is limited by severe constraints on strategic expansion. , Thesis (PhD) -- Faculty of Science, School of Environmental Sciences, 2023

  • Description: This study evaluated South Africa’s legislative framework for public infrastructure investment to determine its effectiveness in reducing unemployment. The study is primarily driven by South Africa’s persistent challenge of unemployment with Statistics South Africa estimating the unemployment rate at 35.5 per cent or 7.9 million labourers. Persistently high levels of unemployment harm the socio-economy as unemployment increases poverty and contributes to inequality. For the government an increase in expenditure on social relief programmes, while offering some relief, decreases revenue collection. In order to mitigate this imbalance, the South African government identified public infrastructure investment as a stimulus for economic growth and create employment, such as in the Expanded Public Works Programme initiative. The legislative framework is an important aspect of study as policy is legitimised and implemented through the legislative framework. Previous studies have focused on the effect of fiscal policy on economic growth and employment creation. These studies have also used quantitative data analysis to explain the relationship between fiscal policy, economic growth, and unemployment. Other studies have focused on public policy planning and implementation, and some of the policies that have been implemented to address unemployment. This study focused on public infrastructure investments specifically rather than fiscal policy in general. The study also examined the legislative framework to determine whether it is effective in reducing unemployment through public infrastructure investment. The study made used qualitative data analysis as the researcher undertook a document analysis of publicly available documents which were sampled using a purposive sampling technique and analysed using the thematic analysis method. The findings of the study were that the legislative framework supported employment creation through public infrastructure investment through the establishment of a public institution to support the construction industry, the use of local content as inputs and labour-intensive technologies in the infrastructure delivery process. The legislative framework was not effective in supporting the policy, which is demonstrated by the perpetually high unemployment rate despite unemployment alleviating initiatives being implemented in the early and mid-2000s , Thesis (MSc) -- Faculty of business and economic sciences, 2023

  • Description: In this study, I evaluated the Participatory Guarantee System (PGS) as a framework to support the growth and certification of small-scale organic farmers. I used the interpretivism and constructivism lenses to understand the PGS from the perspective of members of three PGS groups. The research was qualitative, treating the three PGS groups as case studies. I collected data using focus groups, semi-structured interviews, questionnaires, field notes and observations. The theoretical frameworks that guided the research and data analysis were Socio-ecological Systems (SES) based principles and the Multi-Level-Perspective (MLP) framework. The data were analysed using Atlas.ti content analysis software. The key results were grouped into four themes: capacity; market and logistics; learning process; and disturbance, shock and stress. The theme of ‘capacity’ dealt with the functioning of a PGS, where three categories were identified: group composition and capacity; resource limitations and institutional support; marketing and consumer education. The more diversity in age, education and culture of PGS stakeholders, the better performance and chances of continuity and propagation. PGS has limited capacity partly due to its voluntary nature and infancy. It needs institutional support to grow and be useful for members. Department of Agriculture extension officers knew little about organic farming, thus limiting their engagement and assistance to such farmers. The theme of ‘market and logistics’ looked at the various factors that influence the farmers’ market reach. The perception from the members was that there was minimal consumer awareness about organic agriculture and the PGS. The marketing of organic produce relied largely on the individual farmer’s efforts and ability to search for and secure markets. The theme of the ‘learning process’ was categorised into learning and knowledge exchange. Members of the PGS groups highly regarded the invaluable knowledge shared through farm visits and online platforms, such as their WhatsApp groups. This knowledge improved and informed their farming techniques and led to the growth of v their skill base and experimentation. They viewed the way knowledge was exchanged as non-threatening and highly useful. The fourth theme of ‘disturbance, shock and stress’ dealt with the effects of COVID19. The three groups were all affected by lockdown restrictions (at the time of data collection) and were initially cut off from their usual markets. This led to a loss of income, loss of farm staff and a loss of the desired growth of the farms. The group’s diverse farming practices bolstered their resilience, enabling them to adapt and try alternative marketing strategies. , Thesis (MSc) -- Faculty of Science, School of Natural Resource Management, 2023

  • Description: An explorative study into the introduction of sugar tax in the sugar industry: A case of Illovo. The purpose of this study was to assess the impact of the sugar tax on the South African sugar industry, Illovo Sugar in particular. This tax was introduced in 2018 and it only affected the beverage industry, with its effects being concentrated on industrial sales. The government's intention was to reduce the rising levels of non-communicable diseases such as diabetes and heart diseases, in response to the increased sugar consumption in the country. In addition, the introduction of this tax was expected to reduce sugar consumption in the country, thereby improving public health. Ultimately, the government wanted to encourage citizens to adjust their lifestyles by reducing their sugar intake. To this end, the sugar tax was implemented with the expectation that it would lead to a decrease in sugar consumption in South Africa. The researcher made use of the qualitative research method to collect the data. This enabled a comprehensive understanding of the research topic, as the participants chosen had been working in the sugar industry for a number of years and could give detailed accounts of the implications of the tax on the industry and the communities. Furthermore, the researcher conducted in-depth interviews with the participants to better understand their perceptions on how the tax had impacted their businesses. The data collected was then analysed according to thematic content analysis, and this produced factual, reliable, and valid results. The findings of this study revealed that the sugar tax had a negative impact on Illovo's business operations. Despite this, Illovo was able to leverage its resources and expertise to devise strategies for mitigating the impact of the sugar tax, allowing them to remain competitive in their industry. This included focusing on independent stores and restructuring staff and resources to manage the lower sugar demand. Additionally, Illovo also looked at selling sugar to more profitable customers, helping to reduce costs and associated risk. Despite the strategies adopted, further research is recommended in order to gain a more comprehensive understanding into the phenomenon using a large sample size. This v would allow for further insights into the impact of the sugar tax on the South African sugar industry and whether any changes need to be made in order to ensure that it continues to remain competitive in the industry. Furthermore, research should also be conducted into the implications of the sugar tax on other sectors of the economy, as policy makers may need to consider the possible effects on other industries and even on the government itself versus the possible benefits to the public. Additionally, this research could also be extended to include a longitudinal study in order to capture any changes that take place in the years to come. These changes may include further price adjustments, changes in consumer behaviour, and any possible implications on public health. This would allow for a greater understanding of the implications of this tax for both the industry and society. , Thesis (MA) -- Faculty of Faculty of Business and Economic Sciences, 2023

  • Description: In this work, the selectivity behaviour of two host compounds, namely N,N’-bis(5-phenyl-5- ibenzo[a,d]cycloheptenyl)ethylenediamine (H1) and N,N’-bis(5-phenyl-10,11-dihydro-5- ibenzo[a,d]cycloheptenyl)ethylenediamine (H2), was assessed in mixtures of difficult-toseparate compounds, including the xylenes and ethylbenzene, pyridine and methylpyridines, and anisole and methylanisoles. These host compounds were synthesized using Grignard addition reactions with phenylmagnesium bromide on dibenzo[a,d]cyclohepten-5-one and 10,11- dihydrodibenzo[a,d]cyclohepten-5-one, respectively. The resultant alcohols were treated with perchloric acid to form the corresponding perchlorate salts, which were then reacted with ethylenediamine to afford the required H1 and H2 host compounds. Yields were 95 ad 52% for this final step in each case. An investigation of the conformations, both from experiment (using single crystal X-ray diffractometry (SCXRD) on the apohost compound) and computational calculations was undertaken. Unfortunately, H1 always crystallized out as a powder unless this host compound formed a complex with a guest species, and so could not be subjected to SCXRD analysis as apohost alone. However, a single crystal structure for apohost H2 was successfully obtained and compared with computational data from a previous investigation. It was observed that the conformation of apohost H2 compared favourably with that of the lowest energy conformer from that work. In single solvent recrystallization experiments with o-, m-, p-xylene (o-Xy, m-Xy, p-Xy) and ethylbenzene (EB), both H1 and H2 formed complexes with only one of the four guest species, namely p-Xy and o-Xy, respectively. The host:guest (H:G) ratios were 1:1 for both of these complexes. In the equimolar guest/guest competition experiments, inclusion complexes only formed when p-Xy or o-Xy, respectively, were present in the mixtures; if p-Xy (for experiments with H1) or o-Xy (H2) was absent from these mixtures, only apohost was recovered from the glass vessels. Three selectivity profiles were constructed for each of these host compounds, in which each one was recrystallized from binary mixed guests in various proportions. These demonstrated an overwhelming preference of H1 for p-Xy and H2 for o-Xy, which concurred with the results from the equimolar experiments. Thermal analysis using H1∙p-Xy revealed that this complex was unstable at ambient conditions, while SCXRD explained this observation: this complex may be defined as a true clathrate since no host‧‧‧guest interactions were identified at all, and the guest was retained in the complex by means of steric factors alone. Furthermore, the guest molecules resided in wide open channels that may have facilitated the guest release process. H2∙o-Xy, on the other hand, was stable at room temperature, and the guest release event only commenced at 69.7 °C (Ton). This too was explained by SCXRD analyses in that interactions between host and guest species were observed in this case. Additionally, the guest molecules were housed in discrete cages, which made their escape more challenging compared with p-Xy in H1∙p-Xy. It was concluded that, in this guest series, both of the host compounds would be effective as separatory tools employing host-guest chemistry protocols due to their remarkable selectivities for p-Xy (H1) and o-Xy (H2). , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2023

  • Description: Palaeoenvironmental studies are important as they aid in reconstructing histories of past landscapes and provide key long-term information for the conservation and management of ecosystems. The southern Cape coast is a focus area for palaeoenvironmental research due to its high botanical and climatic importance. A three-metre sediment core was retrieved from Whale Rock wetland (Plettenberg Bay, southern Cape Coast) and spanned ~8000 years – a large proportion of the Holocene epoch. Diatom data preserved in palaeosediments of the Whale Rock wetland are presented within this study. A total of 48 diatom species was identified. Based on the multivariate statistical analysis, the diatom assemblages were divided into three zones: Zone WR-1-A (~7200 – 6450 cal yr BP); Zone WR-1- B (~6450 – 6250 cal yr BP) and Zone WR-1-C (~250 cal yr BP – to present). Two diatom preservation hiatus periods were observed at ~8000 – 7200 cal yr BP and ~6400 – 230 cal yr BP. The results indicated that benthic diatom species were significantly dominant throughout the Whale Rock record. The diatom evidence revealed that the Whale Rock wetland system freshened over time as diatom species identified in Zone WR-1-A and Zone WR-1- B indicated marine influences whereas Zone WR-1-C displayed a dominance of species that thrive in freshwater conditions. A transitional phase occurred at ~6400 cal yr BP where abrupt changes began prior to the significant ~6400 – 230 cal yr BP diatom preservation hiatus period. Principal Component Analysis showed that salinity was the main environmental driver of change impacting the species abundance and diversity of diatom communities within the wetland system throughout the Holocene. When compared with regional palaeoenvironmental and palaeolimnological data, it is evident that several other wetland systems moved from a marine/brackish favoured system to a freshwater system with the transitional phase occurring at different periods within the Holocene. This study indicated that diatoms are powerful biological proxies of environmental change. It is recommended that the site be revisited to investigate further the hiatus phases to further explore the lack of diatom preservation for these periods and to also contribute more palaeoenvironmental proxy evidence as well as modern hydrological information. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

  • Description: The aim of this study was to examine impact of Covid-19 on organisation’s work environment in South Africa, based on Black Management Forum’s views. The outbreak of Covid-19 led to disruption on organisation’s ways of working, this was due to lockdown rules and regulations, restrictions imposed by Government to curb the spread of the virus. The study used quantitative method approach; online survey questionnaire was distributed to recruited Black Management Forum (BMF) members who were willing to voluntarily participate via an email and WhatsApp platform. These members were sampled using convenience and snowball non-probability sampling techniques. The concepts of the study were scientifically hypothesised to determine whether such associations exist within the context of the work environment and productivity within the different corporate sector of industries in South Africa. The study findings confirmed that most organisations were impacted, and they changed their ways of work by implementing mostly work partly from home (WPFH) hybrid work model. The study findings also revealed that, workload was more during the pandemic than before, as results of changed work environment. Other finding from the study indicated that most employees adapted well to changes, understood the need for change and they performed well. Most employees also felt more productive and well supported and respected by managers. Service sectors were more impacted than other sectors and they showed more productivity as well. Most respondents felt that the adopted ways of working would remain post-pandemic and that they prefer this hybrid model of working because it gave them an opportunity to manage their own time. vii The research is significant as it critically examined how a pandemic can create organisational changes and the extent to which organisations must adjust. The research also provides policy recommendations that could assist corporate organisations in adopting new ways of working. , Thesis (PhD) -- Faculty of Faculty of Business and Economic Sciences, 2023

  • Description: Agricultural development is a prerequisite for most economies to grow. Agricultural activities are key to food security and sustaining livelihoods globally. Within the African continent, more women are employed in agriculture and agribusiness activities than other sectors. As main contributors to the labour force in the agricultural sector, women get involved in many agricultural and agribusiness activities to sustain their families. With over 60% of women in Sub–Saharan Africa involved in agriculture, there is need to explore and assess the role they play in promoting agribusiness with special focus on Kariega, in South Africa. The identified participants in the study, as self-employed farmers, participate in agribusiness, thereby creating employment opportunities whilst generating personal incomes. Several benefits to female involvement in agribusiness were identified, including the ability to sustain families, stable cash flow, and empowerment. Several challenges were identified, including adequate capital, inaccessibility to private land, droughts, water scarcity, climate change effects and stigmatisation. Through a feminist qualitative methodology, the study utilised semi- structured interviews to collect data from 10 women involved in agribusiness around Kariega, Nelson Mandela Bay. Themes from the findings are analysed to highlight the important role played by women toward agribusiness, their achievements, government and private sector role and the hinderances still faced by these women in agricultural cooperatives. Discussion from the analysis included a framework of recommendations, for policy makers, development practitioners and future researchers. The study found that all stakeholders involved in the agricultural sector should work together for sustainable agricultural development and sustainable development goals to be achieved. Sustainability among women farmers can be achieved by (a) Increasing government intervention and support (b) Climate smart agriculture practices (c) Overcoming stigmatisation (d) Encouraging and involving the youth (e) Diversification and integration of farm businesses and (f) Using contract farming. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2023

  • Description: This study investigated the effectiveness of the communication strategies used to implement the migration of telephone services from post-paid to prepaid billing at TelOne Zimbabwe. This study adopted the Freeman‟s stakeholder theory and the Lewin‟s change model to analyse the factors that influenced the effectiveness of the communication strategies used by TelOne before, during and after the change implementation as a way to communicate the initiative with its stakeholders. A qualitative approach was utilised and the key research methods used included document analysis, participant observation, as well as 21 face-to-face and 79 telephonic semi-structured interviews conducted with respondents from among TelOne managers, employees and the customers. The documents and respondents were purposively sampled based on the researcher‟s knowledge of their relevance in the study. The findings revealed several factors that mired effective change communication strategies such as company image, stakeholder recognition and communication centralisation. To curb these communication challenges, the study proposes Thrive organisational communication change model TOCC that encourages organisations to communicate the initiative to its relevant internal and external stakeholders considering their views and addressing factors that might hinder effective communication as a strategy to enhance successful change management. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2023

  • Description: This study's goal was to pinpoint the challenges and untapped opportunities associated with Coastal and Marine Tourism (CMT) in the Swartkops River Estuary (SRE). CMT has become the biggest segment of the travel industry. Moreover, this form of alternative tourism is the most significant and fastest developing economic activity in the ocean. The objectives of this study were to identify the challenges that hinder the development of CMT in SRE, to determine opportunities for CMT in SRE, to evaluate NMBM’s efforts in creating and sustaining CMT in SRE and to evaluate the status of CMT in SRE in terms of CMT related development. This study fit within the interprevist paradigm and made use of a qualitative research approach and design as well as inductive reasoning. The qualitative research design consisted of data being collected through document and content analysis. Data was analysed using data analysis process of Miles and Herman (1994) as well as the coding and developing of specific themes that emerged from the data. The data in this phase was presented both in narrative format and tables. The document analysis used in this study was established based on the objectives of this study. The findings of this study revealed that key challenges that hinder the growth of CMT in Swartkops River Estuary are environmental impacts that include pollution, over enrichment, inappropriate development, overfishing, destruction of mudflats, limited freshwater inflow, destruction of vegetation and climate change. The findings also revealed that there are opportunities for CMT in SRE such as promoting SRE as a popular ecotourism destination by developing ecotourism nodes. These include environmental education at the Aloes Nature Reserve's and the Swartkops Estuary south-east section, sustainable ecolodges and conference centres. The study recommends that the Nelson Mandela Bay Municipality should organize educational programmes to educate local people about the significance of conserving and safeguarding the environment for future generations. These findings also posed certain challenges linked to those identified in the analysis. , Thesis (MPhil) -- Faculty of Business and Economic Sciences, School of Economics, Development & Tourism, 2023

  • Description: Entrepreneurship is one of the corner stones of poverty alleviation as it is a tool for economic growth. As Malawi’s SME sector comprising entrepreneurs is facing challenges such as lack of access to finance, and high business operating costs, collective entrepreneurship has been found to be a possible solution. Collective entrepreneurship occurs when individual’s resources and skills are incorporated into a group so that the innovation process and accessing marketing resources is made easier compared to individual effort. The collective ability of individuals and organisations is important in developing countries as it enables the use of the community as a means of targeting business opportunities and hence promoting growth of the economy. This study’s purpose was to assess the potential of collective entrepreneurship in enhancing economic development in Malawi. Specifically, the study aimed to investigate the youths’ attitudes towards collective entrepreneurship, examine the potential of collective entrepreneurship to empower the youth economically, explore ways of engaging the youth in collective entrepreneurship programmes and identify strategies that could be used to promote economic development by the youth through collective entrepreneurship. The study focused on the youth to increase their empowerment economically, as this element was previously not critically examined. Furthermore, this study was based on the fact that not much research has been conducted in Malawi to guide an entrepreneurship development strategy. The study’s participants were from Blantyre City townships. A survey method was adopted, targeting a population of 90 respondents. Data was collected using 40 questionnaires, 17 in-depth interviews and two focus group discussions. Data was analysed using software packages such as Rev, Microsoft Excel and SPSS. The results of the study revealed that the majority of the youth are ready to participate in collective entrepreneurship ventures as they can potentially empower them economically. The study found ways of engaging the youth in collective entrepreneurship programmes, which included financial institutions such as banks providing timely tailored financing options and engaging responsively with youth. The study identified strategies that could be used to promote economic development by means of collective entrepreneurship including universities supporting young entrepreneurs through courses on collective vii entrepreneurship, and the hosting of incubator and accelerator programmes. The study made several recommendations which among them was targeting the youth in the formation of collective entrepreneurship programmes, developing policies that embrace key success factors for collective entrepreneurship and promoting entities that can foster collective entrepreneurship. , Thesis (MA) -- Faculty of Faculty of Business and Economic Sciences, 2023

  • Description: A Digital Twin is a digital representation of a physical product or entity or a “set of virtual information constructs”. To effectively represent its physical counterpart, the digital representation needs to know about its properties, rules and behaviour. In order to enable this, there is a constant flow of data between physical objects and digital representations. The data contained in the digital representation allows simulations to be conducted and learnings from these simulations enable better decision making without affecting the physical realm. Human Digital Twins duplicate a person, rather than a physical product or artifact. As Human Digital Twins hold large amounts of data about a person and are able to utilise this data to predict a person’s possible behaviour and control a person’s choices Human Digital Twins hold economic value for organisations. Human Digital Twins can be effectively used in consumer choice modelling to determine a person’s preferences and assist organisations in marketing products and alternatives to customers. Location, purchasing behaviour and online activity can be used to predict potential future customer behaviour and choices. In previous studies proposing Human Digital Twins, limited emphasis has been placed on the opinion of the people who have been twinned. There are several ethical and moral implications in creating Human Digital Twins. The perceptions of the twinning process of people have not adequately been researched. Current technology allows Human Digital Twins to be created but challenges lie with the moral and ethical complications in a person’s Digital Twin acceptance. Various factors have been identified in previous research relating to Human Digital Twins. Knowledge, Perceived Usefulness, Perceived Ease of Use, Trust and Technological Proficiency are factors that have an influence on a person’s Human Digital Twin acceptance. These factors were considered as independent factors of the conceptual model while user acceptance was considered the dependent factor of the proposed model. The questionnaire for this study was completed by a sample of 121 respondents, who were reached through convenience and snowball sampling. The questionnaire was primarily distributed to students at the Nelson Mandela Business School in Gqeberha, South Africa. The demographic data indicates that a high number of respondents v reside in the Eastern Cape and the majority of respondents achieved a post graduate degree. This is not necessarily an accurate description of the South African population and the sample used in future studies should be more representative of the South African population. The results indicate that the independent factors Perceived Usefulness, Perceived Ease of Use and Technological Proficiency had significant positive effects on Human Digital Twin acceptance. Two of the original independent factors were split into two sub-factors as a result of the EFA. The independent factor Trust became Human Digital Twin Distrust and Trust in Companies using Human Digital Twins. The independent factor Knowledge became Knowledge about Human Digital Twins and Knowledge about the role of technology. This study based its conceptual model on the Technology Acceptance Model. The model relies on two major determinants, Perceived Usefulness and Perceived Ease of Use, to determine a user’s intention to use and accept a technology. This study added new determinants of acceptance to the original TAM, two of which was found reliable. Knowledge of Human Digital Twins and Technological Proficiency were both found to have a significant positive influence on the acceptance of Human Digital Twins. This study was one of the first to suggest a relationship between Technological Proficiency and the acceptance of a new technology. The managerial recommendations set out to bridge the gap between this study and practice. It is not uncommon for researchers to suggest corrective actions and make strategic recommendations based on the results of a study. This study provided managerial recommendations to marketers who want to employ Human Digital Twins in their strategies. This will allow marketers to test campaigns and improve on existing campaigns much quicker than before and take new products to market with testing marketing strategies at a much quicker pace. Organisations need to be cognisant of the fact that legal issues such privacy, consent, discrimination and copyright will be very important when creating Human Digital Twins. Marketers will not only be able to use information gathered by Human Digital Twins in the real world but in virtual worlds as well. , Thesis (MA) -- FFaculty of business and economic sciences, 2023

  • Description: Across the world, diabetes is one of the leading causes of deaths attributed to noncommunicable diseases (NCDs). In Africa, a huge proportion of African countries’ annual healthcare budgets are consumed by diabetes (7 %) with many already experiencing healthcare budget deficits. The prevalence of diabetes is rapidly growing and threatens the economic productivity and livelihood of many families within the region. The world leaders have invested heavily in reducing the pandemic by focusing on increasing the availability of affordable essential medicines in developing countries. The majority of diabetes cases are due to type 2 diabetes (90 %) and may be treated using oral hypoglycaemic drugs (OHDs). Repaglinide (REP) is a non-sulfonylurea insulin secretagogue (meglitinide) with greater HbA1c reduction than metformin in newly onset type 2 diabetic patients, however due to the high price of REP outside Asia, cheaper and less effective OHDs are prescribed to patients. Many of the reported synthetic routes towards REP utilize a key intermediate, 2-(3-ethoxy-4- iethoxycarbonyl)phenyl)acetic acid. The key intermediate contributes significantly to the price of REP as many of the intermediate’s synthetic routes suffer from long reaction times, low yields and industrial complex approaches. Therefore, this has prompted us to investigate an efficient process towards the synthesis of 2-(3-ethoxy-4-(ethoxycarbonyl)phenyl)acetic acid using multiple continuous flow systems. , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2023
