- Description: This study is set within the South African Police Service (SAPS). The purpose of the study is to construct an integrated service excellence model, in order to improve service quality in the South African Police Service as a whole and to continuously improve service excellence in the assistance provided in the Northern Cape in particular. Furthermore, the study was intended to identify gaps in the quality of services provided by the SAPS to the various communities in the Northern Cape. The development of a service excellence model for the assessment of the services provided by the SAPS is justified, because it is an essential means to improving the services rendered, which will be beneficial to both the SAPS and the community. Service failures negatively impact relationships and marketing efforts and thus complicate service providers’ relationship-building efforts. Therefore, service providers endeavour to restore customers’ post-recovery satisfaction through service recovery efforts to retain their customers. However, the influence that customers’ relationship intentions have on this process has not been considered. Previous research on relationship intention in South Africa focussed only on developing a valid and reliable relationship intention measurement scale. This study employed both the quantitative and qualitative research approaches to validate the research questions and authenticate the problem statement. The triangulation approach allowed the researcher to effectively engage the strengths of both research methodologies. The research findings from the empirical survey were statistically analysed using statistical procedures. The data analysis, derived from the qualitative research approach, involved thematic content analysis. The sample populations for the study comprised ward councillors, selected senior officials and community members. For the quantitative approach, questionnaires were distributed to respondents. One-on–one interviews were conducted with senior managers as the qualitative component of the study. , Thesis (PhD) -- Faculty of Humanities, School of Governmental and Social Sciences, 2020

- Description: In this thesis, we present adsorptive removal of nitrogen-containing compounds from fuel oil as an alternative to complement conventional hydrotreatment to obtain ultra-low sulfur and nitrogen levels. This is in cognizance of the challenges nitrogen-containing compounds pose to the hydrotreatment process, particularly their inhibition and/or poisoning of the catalysts used in the process, of which basic nitrogen-containing compounds are the major culprits. Selectivity is the biggest challenge for adsorptive removal of nitrogen-containing compounds. We explore reticular synthesis of metal organic frameworks and the use of coordinatively unsaturated metal sites in 1-dimensional coordination polymers to achieve good selectivity for nitrogen-containing compounds. In the first part of the thesis, reticular synthesis of metal organic frameworks to control the size of the cavity, and strategically use the linkers and metal centres was envisaged. In this work we explored variation of the metal centres in the secondary building units (SBUs of the MOFs as the first step to the testing and implementation of the design strategies. Carbazole, representing carbazoles which the major compounds that remain in hydrotreated fuel, was the target compound. Four MOFs of zinc (Zn-CDC-bpe), copper (Cu-CDC-bpe), nickel (Ni-CDC-bpe) and cobalt (Co-CDC-bpe) based on the formation of a dinuclear metal paddlewheel SBUs with the ligand 9H-Carbazole-3,6-dicarboxylic acid (H2CDC) and occupation of the axial positions of the paddlewheel by 1,2-Bis(4-pyridyl)ethane (bpe) to form porous networks were synthesized. A fifth MOF containing only CDC which forms a [Zn4O(O2C-R)5(O2HC-R)] SBU was also synthesized (Zn-CDC). The ligand H2CDC was inspired by the possibility of improving selectivity for carbazole via π–π interactions through the more preferred parallel-offset stacking as well as the possibility for further substitution of the carbazole N-H to add groups that improve selectivity. The sizes of the MOF cavities can then be controlled by choosing different lengths of ligands analogous to 1,2-Bis(4-pyridyl)ethane (bpe), e.g. 4,4’-bipyridine and pyrazine. All the MOFs showed good selectivity of carbazole. The Zn-CDC MOF also had good selectivity for the basic nitrogen-containing compounds tested: quinoline, isoquinoline, quinaldine and 1-naphthylamine. Its uptake of carbazole was also slightly higher. This was attributed to the presence of an unsaturated Zn site in the SBU. Adsorption in all the MOFs was primarily due to physisorption. It was concluded that the role of the metal centre does not play a significant role in the adsorption of carbazole besides providing a template for reticular synthesis. , Thesis (PhD) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2021

- Description: Zirconium (Zr) alloys are used as fuel cladding material in all modern water cooled commercial nuclear reactors. Zr alloys have many desirable properties for the nuclear reactor core environment, however, it also has a weakness in that overheated zirconium alloy fuel rods react with hot steam resulting in the release of hydrogen. High temperatures increase the oxidation rate and hence the hydrogen production rate which in turn increase the risk of a hydrogen gas explosion such as what is surmised to have happened in the 2011 Fukushima Daiichi nuclear plant incident. The some of the hydrogen produced will also diffuse into the zirconium alloy and form zirconium hydrides which will weaken the original zirconium alloy material. The development of accident tolerant fuel became a major focus area after the Fukushima event in March 2011 with the U.S. congress directing the U.S. Department of Energy to develop fuel with enhanced accident tolerance at high temperatures. The main objective in the case of zirconium alloy cladding has been the modification of cladding surface layers by coating or doping in order to reduce the oxidation rate and hydrogen generation rate by the reaction of steam with zirconium alloy cladding at high temperatures. This thesis focuses on two surface modifications to decrease the surface corrosion rate of ZIRLOTM (the Zr alloy used in this study) and reduce hydrogen uptake by ZIRLO. The first modification involves an oxidation-resistant nano-crystalline diamond (NCD) film deposited on ZIRLO. The NCD layer was deposited in a microwave plasma-enhanced linear antenna chemical vapor deposition (MW-LA-PECVD) system after immersion of the ZIRLO tubes in a water-based solution containing nanodiamonds. ZIRLO tube samples were coated with 200 nm and 500 nm thick NCD layers. The 200 nm thick NCD coated ZIRLO was kept as control sample whereas the 500 nm thick NCD coated ZIRLO was exposed to steam oxidation at 360 °C for 90 days. The results revealed that the NCD exfoliated in some areas leaving the ZIRLO exposed to the steam. In the areas where the diamond did not exfoliate, the diamond was still attached to the ZIRLO with an amorphous carbon layer present between the NCD and the zirconium oxide layer.The transmission electron microscopy (TEM) results of this study indicate the presence a sp3 – hybridised diamond phase for the NCD layer as well as an intermediate amorphous carbon layer between the NCD and ZrO2 layers. Analyses of the area where the NCD layer had exfoliated showed no evidence of an NCD layer. It is possible that the amorphous carbon layer between the diamond and the zirconium oxide is responsible for weak interfacial bonding leading to partial exfoliation during oxidation in steam 360 °C for 90 days. In the second modification, the effectiveness of a Cr doped ZrO2 layer to reduce the migration rate of hydrogen in ZrO2 was investigated. The ZIRLO tube used for this part of the study did not have a thin oxide passivation surface layer. Two different procedures were used to create chromium doped zirconium oxide surface layers on ZIRLO. The ZIRLO surface was coated with chromium using cathodic arc deposition followed compression plasma flow (CPF) treatment to facilitate intermixing of the Cr and the ZIRLO. In procedure 1, the surface modification was achieved through the incorporation of chromium into the zirconium surface layer using a compression plasma flow (CPF) technique, followed by the oxidation of the chromium doped zirconium. The oxidation process was conducted at 500 °C for 6 hours. In procedure 2, the chromium was incorporated into the zirconium oxide layer again using the CPF technique. Hydrogen desorption was measured from pure ZIRLO and CPF modified samples using a special gas reaction controller system. The key finding of the results is that the chromium doped (incorporated) zirconium oxide layer on ZIRLO sample exhibited the lowest hydrogen desorption rate of all the samples analysed. This indicates that H in the Cr doped zirconium oxide layer had the lowest mobility of all the samples investigated. This is consistent with the theoretical predictions that the doping of ZrO2 by Cr reduces the solubility of hydrogen in ZrO2. , Thesis (PhD) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2021

- Description: In 1998, following a recommendation made by the United Nations Educational, Scientific and Cultural Organisation (UNESO), the Joint United Nations programme on HIV and AIDS (UNAIDS) adopted a cultural approach to HIV and AIDS prevention and treatment for sustainable development. Cultural identity, values and norms are all influential factors in health decision making and may be especially important in the context of HIV infection. The research aim of this study was to explore and describe the experiences of HIV positive Xhosa males in relation to understanding how cultural identity, cultural values and norms influence the health decision making behaviour of Xhosa males. A qualitative study design was adopted. A descriptive and interpretative approach was applied. Semi-structured interviews were conducted with 10 HIV positive Xhosa males aged 25 to 49 years in four primary healthcare clinics in the Nelson Mandela Bay. Thematic data analysis was utilised to analyse the data through the lens of literature and the bio-ecological model. The data was coded by the researcher and an independent coder. Three themes and six sub themes emerged from the study. Theme one is: significance of culture for HIV positive Xhosa males. Theme two is: perspectives on factors that have an influence on health decision making. Theme three is: perceived beliefs and perceptions about HIV and AIDS in the Xhosa ethnic group. The study indicated that cultural factors such as ancestral beliefs regarding illness, traditional circumcision, initiation school and masculine roles and expectations influenced health decision making of the Xhosa males. In addition, there are other factors that have an influence on health decision making such as psycho-social factors of peer pressure and biological factors which include physical developmental changes. In addition to factors that have an influence to health decision making, it became apparent in the study that there was perceived stigma attached to HIV and AIDS from family members and the Xhosa community. Participants also experienced internalised stigma and expressed a v fear of not having an heir; thus, influencing risk taking health decision in fear of being stigmatised. Perceptions of HIV positive Xhosa males on cultural factors that have an influence on health decision making such as risk behaviour and adherence to treatment are: ancestral belief of protection against illness, traditional circumcision, initiation school and masculine roles and expectations. , Thesis (MA) -- Faculty of Health Sciences, School of Behavioural Sciences, 2020

- Description: This treatise explores customer experience in the South African banking industry and its importance for the success of retail banks. Customer experience leaves a memory that has critical effects on future spending of not only direct customers, but others around them. The main issues addressed by this study are how customer experience is a differentiator in the South African banking industry. The banking industry is a highly competitive industry and the importance of customer service in the banking industry is essential for business if they wish to stay relevant and have sustained continuity and growth. In today’s fast-evolving business life, customer experience has become the new battleground for businesses and banks can no longer rely on products or prices to be competitive. Retail banks now need to compete by providing exceptional customer experiences, which cannot be imitated by their competitors. Services provided by South African banks are very similar and banks need to use superior customer experiences to gain competitive advantage over rivals. Understanding customer experience in achieving customer satisfaction is essential to ensure that banks have satisfied customers who encourage others to join or stay with the bank. Once understood, customer experience will assist bank managers to provide inimitable and superior experiences, resulting in business success. The study aims to assist South African banks to improve customer experiences by investigating customer experience and factors that influence it. Definitions and theories are discussed as well as the importance of customer experience in the South African retail banking industry. This study specifically explored the role of the customer experience through factors brand experience, service experience and post-purchase experience. Each factor is statistically explored and its importance highlighted. An empirical study, using a questionnaire, was conducted amongst 858 respondents. The purpose of this was to determine the satisfaction levels of South African retail banking customers, by using data analyses and descriptive and inferential statistics to test the factors identified in the conceptual model. , Thesis (MA) -- Faculty of Business and Economic Sciences, NMU Business School, 2021

- Description: The notion of customer experience has gained prominence in the field of marketing over the last three decades. It has become a strategic imperative for firms in order to ensure sustained business growth. A positive customer experience not only has the ability to promote customer loyalty but can also assist firms in encouraging brand advocacy. While customer experience has been explored in several contexts, regions and industries, customer experience in South Africa’s banking and grocery retail sectors has not yet been adequately explored. Therefore, this study attempts to provide a comparative analysis of these two sectors and in turn present a model for improving customer experience as a marketing tool. The execution of this study requires a literature review to investigate the field of customer experience. This literature review assisted in developing a conceptual model for customer experience in the attempt of improving customer experience quality. Furthermore, this Treatise pursues a positivistic research approach using quantitative methods of analysis. Factor analysis was conducted using data gathered from an online questionnaire disseminated via e-mail. The sample of this study was selected at random using convenience and snowball sampling. A sample size of n = 858 is used in this study. Descriptive and inferential statistical analysis were conducted on the data. The primary contribution of this study was the presentation and statistical assessment of an exploratory factor analysis of factors influencing customer experience in South Africa’s grocery retail and banking sectors. This study found that the independent factors of Brand Experience, Service Experience and Post-purchase Experience were all found to have a positive effect on the overall customer experience. In the grocery-retail sector, Post-purchase Experience was found to have a strong positive correlation with customer experience. Brand Experience and Service Experience were strongly correlated with each other as independent factors, but did not demonstrate any practical or statistical significance in relation to the dependent factor, Customer Experience. However, in the banking sector, all of these factors demonstrate positive correlations with Customer Experience that are statistically and practically significant. The model presented in this study identifies the determinants of Customer Experience within both sectors. , Thesis (MBA) -- Faculty of Business and Economic Sciences, NMU Business School, 2021

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

- Description: The World Bank has emphasized the role of savings in financing domestic fixed capital formation, technology, education, employment and economic growth. Many African countries have experienced decreased savings and increased current account deficits worsened by the global financial crisis and capital outflows. This study seeks to explore the determinants of savings and determine the savings trend of African countries compared to that of the world. To this end, annual time series data for 20 representative countries from different economic groups were obtained from World Bank Indicators, International Monetary Fund (IMF), Penn World Tables and Integrated Network for Societal Conflict Research (INSCR) database over the period 2000 to 2018. The Panel ARDL/ Pooled Mean Group estimator was used to analyse the data. The main findings were that household variables, capital flow variables, human capital variables, institutional quality variables, financial and other social macroeconomic variables determine savings. Further, the speed of adjustment show causality from the explanatory variables to savings. The use of income and monetary policy dummy variables indicates that there is no difference in determinants of savings for countries with different income groups and monetary policies. It was recommended that African countries invest in education and ICT infrastructure, improve their financial systems and restructure policies on good governance and political stability as this has a significant effect on savings. The study was limited by a lack of time series data for all African countries, therefore, future research involving an increased sample size and variables were recommended. , Thesis (MCom) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 2021

- Description: Waste tyre is becoming a global environmental problem due to challenges in its disposal management and the fact that it poses fire hazards and metal leaching risk. Waste tyre can also breed mosquitos if it traps water thereby becoming an environmental health problem. There is also a portion of unused tyre in a waste tyre that is valuable and should be recycled. In South Africa waste tyre recycling is in three industries, one of which is crumb rubber where waste tyre is applied into various sized particles called crumb rubber. Crumb rubber can be applied in environmental remediation as an organic and inorganic pollutants’ adsorbent. Considering the fact that South Africa’s environment is loaded with heavy metal pollutants due to contributions by mining and agriculture as examples, it is postulated that crumb rubber produced in South Africa could be used to remediate the environment of these toxic metals. In this study adsorption of Pb (II) and Cu (II) from the synthetic waste water using waste tyre crumb rubber produced in South Africa was studied. Crumb rubber was activated using aqueous NaOH (0.02%) to make crumb rubber wettable followed by it being treated with 0.02 % acidified KMnO4 for modification of its ability to sorp positively charged metal species. Trial sorption experiments on 50 mg / L Cu (II) were successful with sorption of over 70% in 250 minutes. Final optimization of the sorption of combined Pb (II) and Cu (II) was studied using a full factorial design and optimum conditions of sorption were found to be pH 5.4; [metal] 0.617 mmol / L for Pb (II); and pH 5.4; the optimization of Cu (II) was found to be pH 5.4; [metal] 0.777 mmol / L. In Pb (II) sorptions the mechanism of adsorption on the activated crumb rubber was found to be following the Freundlich model indicating that the adsorption seemed to occur on a multilayer adsorbent, while the mechanism of copper(II) adsorption on to the activated crumb rubber was found to be following Langmuir model, indicating that the adsorption seemed to occur on a monolayer. With adsorption percentages ranging from 98.2 % to 100.0 %, for Pb (II), the crumb rubber produced under the conditions of this study, can be used in South Africa for selective removal of Pb (II). , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2022

- Description: There has been a gaping variance between the number of mobile phone users and landline users in South Africa (RSA). Results from an assessment in 2011 suggested that 29 million South Africans subscribed to mobile phones versus 5 million landline users (Balabanoff, 2014). The exponential growth of mobile applications has been precipitated by the increased growth of the mobile phone market. This growth is coupled with numerous advantages that mobile services bring to the user, such as better operability, productivity advances and entertainment (Balabanoff, 2014). Even though adoption strategies regarding mobile banking have been studied in various parts of the world, acceptance of mobile banking applications in South Africa has not been greatly researched. Hence, this study focused on exploring consumer behaviour and acceptance towards adopting mobile banking in South Africa, where mobile banking is at an elementary stage, but provides potential benefits to both users and business at large. A quantitative research style was followed by this research. An electronic quantitative questionnaire was distributed to South African civilians who are eligible to hold bank accounts in their own names. The research was then conducted on a sample size of 86 respondents. Due to limitations on time, this study utilised convenience sampling. Data gathered from the questionnaires was examined using statistical analysis to scrutinise the correlation between the variables used in the research model, this being Unified Theory of Acceptance and Use of Technology (UTAUT) model. The UTAUT is commonly used to predict and explain factors that influence the adoption of technology by users. These factors help decision-makers in formulating technology acceptance strategies. , Thesis (MBA) -- Faculty of Business and Economic Sciences, NMU Business School, 2021

- Description: There is increasingly stringent legislation on the environmental impact of energy production from coal combustion, and this has led to growing pressure to reduce the emission of greenhouse gases (GHGs). Thus, there is a significant need to develop and implement clean coal combustion technologies that would reduce the environmental gas pollutants. For power generation, the co-firing of biomass fuels at conventional coal-fired power stations is recognised as one of the low-cost, low-risk options to achieve significant reductions in GHG emissions. When coal is co-utilized with biomass there is added attractiveness because the biomass is CO2 neutral, and there is interest in using waste biomass and microalgae. Thus, the co-combustion of coal and biomass for energy production results in pollutant reduction, especially in the emissions of NOx, SOx, volatile organic compounds and polyaromatic hydrocarbons. The synergistic activity observed for toxic organic emissions is not well understood and is thought to involve chemical interaction between the volatiles from each fuel coupled with possible catalytic activity from the inorganic constituents of the fuels. The characterization of co-firing products and gases emitted from coal and microalgae (particularly the Scenedesmus strain) co-combustion has received limited attention. Therefore, this study seeks to understand possible interactions occurring during co-combustion of coal and Scenedesmus microalgae (Coalgae®). Additionally, the study aims to determine the effect of co-firing coal and Scenedesmus microalgae on CO2, SO2 and NOx emissions. The term “Coalgae®” refers to the mixture of coal and microalgae biomass. The study looks at physico-thermal characteristics as well as CO2, SO2 and NOx emissions of various coal-microalgae blending ratios by mass; 100:0 (coal), 95:5 (Coalgae® 5%), 90:10 (Coalgae® 10%), 85:15 (Coalgae® 15%) and 80:20 (Coalgae® 20%). Characterization techniques carried out included proximate and ultimate analyses, Fourier-transform infrared (FT-IR) and Scanning electron microscopy and X-ray energy dispersive spectroscopy (SEM/EDS). For combustion studies two techniques were applied. Low heating rate was obtained through a Thermogravimetric-Mass spectrometer analysis (TG-MS). Other combustion experiments were performed on the five lumpy fuels (coal and Coalgae® 5% - 20%) exposed to the flame in a fixed-bed combustion reactor. The emission concentrations of CO2 (%), NOx (ppm) and SO2 (ppm) of coal and Coalgae® blends were measured during the combustion of the five materials using a Lancom 4 portable flue gas analyser. The mass reduction (g) and temperature (°C) at the reactor exit were recorded during the combustion tests to compare the combustion behaviour of the four mixtures to that of raw coal. TG-DTG curves of coal and microalgae confirmed that the combustion behaviour of these materials was different. Coal showed one reaction during the combustion process, while microalgae and the Coalgae® blends showed three reactions. A significant reduction in activation energies of 160.4 kJ/mol, 159.6 kJ/mol, 151.3 kJ/mol, and 134.2 kJ/mol for Coalgae® 5% - Coalgae® 20%, respectively, compared to coal (161.3 kJ/mol) was achieved. The lowering of activation energy could be attributed to the relative fixed carbon content. SEM morphology images of ash obtained from the combustion of coal and Coalgae® 5% - 20% confirmed changes in devolatilization and combustion behaviour of solid raw fuel. The ash of Coalgae® blends had higher fluxing elements (Fe, Ca, K and Mg) than coal and this shows possibility of slagging and fouling in combustion systems. The Coalgae® blends showed a synergistic effect due to different combustion characteristics of coal and Scenedesmus microalgae. The combustion results obtained from the fixed-bed reactor showed significant reductions in concentrations of CO2, SO2 and NOx emissions for Coalgae® blends compared to baseline coal. Microalgae reduced CO2 emissions from baseline coal by 14.9%, 19.5%, 23.5% and 31.4% for Coalgae® 5%, 10%, 15% and 20%, respectively. SO2 reductions of 1.9%, 10.6%, 15.8% and 18.2%, and NOx reductions of 22.4%, 26.1%, 24.4% and 16.9% were achieved with Coalgae® 5%, 10%, 15% and 20%, respectively. Moreover, the combustion efficiency of Coalgae® blends increased significantly by up to 14.5% from baseline coal (86.4%) to Coalgae® 20% (98.9%). Based on the above findings, the co-firing of coal and Scenedesmus microalgae biomass was necessary for the reduction of CO2, SO2, and NOx emissions. As such, Coalgae® blends can be considered as alternative fuels in any coal driven process for energy generation. , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2021

- Description: Weather patterns have changed globally with increased fire danger weather conditions, along with poor management and fire suppression, likely contributing to the increase in prevalence of large wildfires. Ecosystems such as temperate broadleaved forests, where fire is limited by climatic conditions, are particularly at risk of altered fire regimes related to climate change. It is thus important to monitor the effects of fire in these ecosystems. Satellite remote sensing is a cost-effective way to assess spatial variability of fire effects on a landscape scale and has become an increasingly used tool for studying fire severity. In the southern Cape of South Africa during October-November 2018, a large wildfire burnt patches of Southern Cape Afrotemperate Forest (hereafter ‘Afrotemperate forest’). This provided an opportunity to investigate the accuracy of a satellite index for fire severity and the effect of fire on Afrotemperate forest survival. The first objective was to verify through field observations the accuracy of the differenced Normalised Burn Ratio (dNBR) as an index of fire severity derived from Sentinel 2 images in Afrotemperate forest. The second objective was to investigate the effect of fire severity and tree size on the post-fire survival of Afrotemperate forest tree species. For the first objective, stem fire severity, estimated from observed damage to the main stem, was recorded for 1 648 trees in 87 plots and linear regression used to test whether the observed measure of fire severity was related to dNBR. For the second objective, stem fire severity and tree survival 19-24 months post-fire were recorded for 40 species and 1 378 trees in 88 plots. Trees were considered to have survived if they resprouted from the main stem or had green foliage in the canopy. The survival response was assessed in relation to stem fire severity and tree size for all trees collectively and for 10 species (with sample size > 40) individually, using logistic regression. A strong linear relationship between dNBR and stem fire severity (r2 = 0.69, p < 0.001) confirmed the accuracy of dNBR as a measure of fire severity in Afrotemperate forest. In the fire investigated, 4 628 ha of Afrotemperate forest burnt of which 67% burnt at low severity, 21% at medium severity and 12% at high severity. The dNBR values associated with fire severity categories were comparable between Afrotemperate and North American forests, suggesting that dNBR values are relatively standard across forest types. Information on the distribution of fire severity facilitates investigation of further questions regarding past and future fire regimes and the fire ecology of Afrotemperate forest. The post-fire survival rate of Afrotemperate forest trees was 45% which is comparable to that in coniferous forests of North America but lower than that in temperate forests of Australia and Portugal and the neighbouring dune thicket which shares several species with Afrotemperate forest. Fire severity had a significant negative effect on survival and tree size a significant positive effect. Total variance explained by the model (for species collectively) was 40.8%, of which fire severity and tree size combined explained 13.2%, and species as random factor, 27.6%. Respective tree species showed differential survival responses – four species showed high survival (> 60% of individuals), while five species showed low survival (< 40%). This study was the first post-fire assessment of the resprouting ability of Afrotemperate forest trees and a third of the trees surveyed (for species collectively) resprouted from the stem. This suggested that resprouting from the stem is a primary means of post-fire recovery in Afrotemperate forest trees, in contrast with previous assertions that several common canopy species, including Podocarpus latifolius, Afrocarpus falcatus, Scutia myrtina, Scolopia mundii and Rapanea melanophloeos, are unable to resprout. Varying resilience to fire among species supports previous suggestions that fire affects species’ composition and diversity in these forests and calls for careful management of fire regimes in the face of global change. , Thesis (MSc) -- Faculty of Science, School of Natural Resource Management, 2022

- Description: Weather patterns have changed globally with increased fire danger weather conditions, along with poor management and fire suppression, likely contributing to the increase in prevalence of large wildfires. Ecosystems such as temperate broadleaved forests, where fire is limited by climatic conditions, are particularly at risk of altered fire regimes related to climate change. It is thus important to monitor the effects of fire in these ecosystems. Satellite remote sensing is a cost-effective way to assess spatial variability of fire effects on a landscape scale and has become an increasingly used tool for studying fire severity. In the southern Cape of South Africa during October-November 2018, a large wildfire burnt patches of Southern Cape Afrotemperate Forest (hereafter ‘Afrotemperate forest’). This provided an opportunity to investigate the accuracy of a satellite index for fire severity and the effect of fire on Afrotemperate forest survival. The first objective was to verify through field observations the accuracy of the differenced Normalised Burn Ratio (dNBR) as an index of fire severity derived from Sentinel 2 images in Afrotemperate forest. The second objective was to investigate the effect of fire severity and tree size on the post-fire survival of Afrotemperate forest tree species. For the first objective, stem fire severity, estimated from observed damage to the main stem, was recorded for 1 648 trees in 87 plots and linear regression used to test whether the observed measure of fire severity was related to dNBR. For the second objective, stem fire severity and tree survival 19-24 months post-fire were recorded for 40 species and 1 378 trees in 88 plots. Trees were considered to have survived if they resprouted from the main stem or had green foliage in the canopy. The survival response was assessed in relation to stem fire severity and tree size for all trees collectively and for 10 species (with sample size > 40) individually, using logistic regression. A strong linear relationship between dNBR and stem fire severity (r2 = 0.69, p < 0.001) confirmed the accuracy of dNBR as a measure of fire severity in Afrotemperate forest. In the fire investigated, 4 628 ha of Afrotemperate forest burnt of which 67% burnt at low severity, 21% at medium severity and 12% at high severity. The dNBR values associated with fire severity categories were comparable between Afrotemperate and North American forests, suggesting that dNBR values are relatively standard across forest types.

- Description: Incarceration is a world-wide phenomenon. It is aimed at punishing those who are in conflict with the law while ensuring that they also undergo rehabilitation processes. Whereas one cannot argue that incarceration is inevitable for those in conflict with the law, it is essential to realise that, when a woman is incarcerated, the remaining family unit members are left behind to deal with all the effects of having a family member taken away. It has been observed that there is an increase in the number of incarcerated women. About two-thirds of incarcerated women reported having one or more minor children, and most of them have lived with their children before incarceration compared to 36% of men (Woodard & Copp, 2016). This study aimed to understand the effects of incarceration of women on the family system in Buffalo City Metropolitan Municipality (BCMM). The study discussed the effects of women incarceration on their children, spouses/partners and care-givers. The available support services were also explored and the coping mechanisms adopted by these families during this period of incarceration. The study utilised a case study research design which was explorative in nature. The data was collected using semi-structured interviews with 15 participants who included eight children, one spouse, one partner and five care-givers. Bowen’s family system’s theory (1978) was utilised as an epistemological framework for the study. The study's findings revealed that the incarceration of women has a negative impact on the family members left behind. This increases the chances of school drop-out, alternative care placement and even criminal involvement of children themselves. It was also discovered that financial difficulties, infidelity and lack of proper support systems for these families are a challenge that is directly associated with incarceration. The study recommended that more efforts should be made to provide support through governmental, non-governmental and communitybased interventions to the families of incarcerated women to prevent these unintended effects. , Thesis (MSW) -- Faculty of Social Sciences and Humanities, 2021

- Description: The car rental industry in South Africa is a highly competitive sector. The industry’s players are constantly faced with the challenge of finding ways in which to enhance their competitiveness. One of the most important challenges for organisations operating in this industry is to deliver the best service to their customers, hence ensuring they retain customer loyalty, growth and securing future profitability. While a number of competitors may rely on various competitive strategies such as lower prices, it could become increasingly challenging for others to adopt similar approaches without comprising profitability. To overcome this challenge, together with Barloworld, Avis has implemented various employment engagement strategies with the aim of attracting, empowering, and retaining an engaged workforce. Research has shown that employees provide organisations with sustainable competitive advantage. More specifically, it has shown that engaged employees outperform disengaged employees. The differentiating factor for organisations in the pursuit of competitive advantage would therefore be an engaged workforce. In order to remain competitive, Avis realised that their employees area source of competitive advantage. In the year 2013, Avis packaged and introduced EVP as a human resources strategy towards winning an engaged workforce. Some of the objectives for taking on this strategy were to increase job satisfaction and motivation amongst employees and thus result in higher job performance. The main purpose of this study was to measure the impact that the introduction of EVP had on employee engagement at Avis. Introducing a structured EVP plan within this organisation was aimed to increase employee engagement and thus, this study aimed to measure the impact of this intervention. A literature review was conducted to expand on the various definitions of EVP, employee engagement and the elements that influence and impact these variables. This research revealed that engaged employees make positive contributions to key business outcomes such as financial performance, productivity and customer satisfaction. An empirical study was conducted by means of a survey with a questionnaire as data collecting tool. The purpose of the structured questionnaire was to validate the findings obtained from the theoretical overview and to assess employees’ perceptions of the EVP elements, engagement factors and the impact of engagement on the organisational success. The population comprised of 142employeesand 65% a response rate was obtained. The key findings of the study indicated that in general employees are engaged and committed to the vision of the organisation. It also indicated that the introduction of EVP improved the manner in which employees’ viewed their leaders and created a leadership culture that was conducive to the success of the organisation. Furthermore, the study validated the existence of a strong positive relationship between EVP, employee motivation, leadership culture, employee retention, compensation and employee engagement. This study provided direction and feedback in the organisation’s attempt to improve engagement levels and ultimately in the pursuit of competitive advantage. , Thesis (MBA) -- Faculty of Business and Economic Sciences, NMMU Business School, 2014.

- Description: Special Economic Zones (SEZs) have been a global phenomenon since the 1960s and have been integral to the transformation of emerging and ailing economies. In 2002 the South African government identified SEZs as instruments for advancing its economy into a higher industrialisation path based the assessment of potential socio-economic gains. Past research findings, however, suggest that South African SEZs, when compared to international SEZ performances, are lagging behind both in terms of delivering a compelling SEZ value proposition and achieving the desired socio-economic gains. Limited research has been conducted on the factors which enable and dis-enable the success of SEZs in South Africa. This study evaluates the factors that enable and dis-enable the effectiveness of South African SEZs in achieving their socio-economic development objectives. Applying a qualitative case study methodology, research was conducted on the East London Industrial Development Zone(ELIDZ), one of the first SEZs to be designated in South Africa in 2002. The study finds that a weak SEZ regulatory framework characterised by slow delivery of important SEZ industrial support has dis-enabled South African SEZs. A complex business environment has also dis-enabled the competitiveness of South African SEZs. The study reveals that while it is easier to conduct business inside the SEZs, South African SEZs are not given adequate policy latitude to be an experimental ground to drive reform that will improve the ease of doing business in South Africa. A challenging labour market marred by low productivity, high production costs and inadequately skilled labour continue to challenge the success of SEZs in South Africa. Poor regional infrastructure and delays in the roll out of fiscal incentives, are also some of the factors that have dis-enabled the success of the East London IDZ. World-class infrastructure inside the ELIDZ, inherent locational competitive advantages and the existence of locational-specific non-fiscal incentives have, however, been the key enablers that have improved the competitiveness of the ELIDZ. Despite some of the notable dis-enablers to the competitiveness of South African SEZs, the ELIDZ has done well in achieving short-term static outcomes such as employment, exports, investment attraction and FDI despite some of the factors that had dis-enabled the zone. The zone has also achieved certain dynamic outcomes such as skills upgrading, industrial upgrading, technology transfer and diversification of the economic output, albeit these still being at low levels. , Thesis (MBA) -- Faculty of Business and Economic Sciences, NMU Business School, 2021

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

- Description: Crude oil is a complex blend containing thousands of hydrocarbons, non-hydrocarbon compounds and heavy metals. These hydrocarbons are mixed with variable quantities of sulfur-, nitrogen-, and oxygen-containing compounds. The combustion of fuel containing organosulfur compounds results in the emission of sulfur oxides (SOx) into the atmosphere. These toxic gases escape into the atmosphere resulting in air pollution, which is a large contributor to global warming. Air pollution also causes pulmonary diseases, allergies and may even lead to human death. It can also cause harm to other living organisms such as animals and food crops. Thus, mandating the reduction of sulfur in organosulfur compounds in fuel to <10 ppmS by the environmental protection agency. Several studies have been conducted to remove sulfur from fuels, most of which have focused on removing refractory sulfur compounds due to the difficulty in removing sulfur in these compounds. However, the currently employed hydrodesulfurization (HDS) catalysts suffer in producing fuels complying with the future standards of fuels quality. Generally, HDS catalysts are made up of metallic components, Co (Ni) and Mo (W), on porous supports, the catalytic activity of these catalysts strongly depends on the amount of NiWS (CoMoS) phases in it and to the extent in which these phases are exposed on the catalyst support surfaces and this is engineered using chelating agents and size of catalysts. To this end, nanosized materials (nanocatalysts) are considered most suitable, as reported active phases of HDS catalysts are exposed, hence improving the hydrodesulfurization of sulfur-containing compounds in fuels. Nanocatalysts results in nanoparticles and when impregnated on a support will results in high surface area, and enhances electronic property, which increases the activity of the catalyst allowing the most refractory sulfur to be removed. The addition of chelating agents such as EDTA, acetic acid, and citric acid further improves the activity of the catalysts by producing more active phases on the catalyst. In this research project, nanocatalysts will be synthesised using mixed metals with and without chelating agents and tested for HDS activity and selectivity towards sulfur using refractory organosulfur compounds in fuels under industrial HDS conditions. This work was divided into two sections, and this dissertation summarizes the research outcomes of each phase. The first section examines the effect of chelating ligands, namely, ethylenediaminetetraacetic acid (EDTA), citric acid (CA), and acetic acid (AA), on CoMo HDS activity and the sulfidation mechanism. In this study, chelating ligands seem to have a beneficial effect on HDS activity. Detailed mechanistic aspects of interactions between chelating ligands and metallic species (Co-chelating ligands) were also studied. Characterization by SC-XRD revealed that the presence of the chelating ligand result in the formation of complex with cobalt, and the effect of this complex was shown by TG-DSC analysis. This showed that the presence of chelating ligand leads a to delay of cobalt sulfidation as the complex decomposes at higher temperatures, which was the main cause of improving HDS activity. It was also shown that chelating ligands play a role in dispersion of metal oxides and sulfided metal oxides (TEM and XPS). XPS results showed low MoS2 phase for CoMo/Al2O3 (45%), while CoMo-EDTA/Al2O3 (63%) catalyst resulted in high MoS2 phases. From all the catalysts, CoMo-CA/Al2O3 (98%) gave the highest catalytic activity, and the increase in activity could be attributed to the formation of octahedral molybdenum oxides as they are easily reducible during sulfidation and result in more dispersed active phases and weak metal-support interaction. The second section examines the effect of a promoter (Rh) and different chelating ligands (EDTA, AA, and CA) on the catalyst RhMo supported with alumina. In this phase, rhodium was used as promoter, the following trend for catalytic activity was observed: RhMo/Al2O3 (88%) > RhMo-AA/Al2O3 (73%) > RhMo-CA/Al2O3 (72%) > RhMo-EDTA/Al2O3 (68%). This could be that the addition of chelating ligand complexed both metallic species retarding sulfidation of both metals, hence lowering the HDS activity. Studies show that it is possible for the citric acid to complex with both promoter and an active metal (Mo), and this might result in the formation of molybdenum dimers, trimers and tetramers which are difficult to sulfide. XPS analysis showed that unchelated catalyst have more MoS2 phases of 63%, hence higher dispersion than the chelated catalyst, this could be the reason for high activity in RhMo/Al2O3 (88%) catalyst. , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2021

- Description: Crude oil is a complex blend containing thousands of hydrocarbons, non-hydrocarbon compounds and heavy metals. These hydrocarbons are mixed with variable quantities of sulfur-, nitrogen-, and oxygen-containing compounds. The combustion of fuel containing organosulfur compounds results in the emission of sulfur oxides (SOx) into the atmosphere. These toxic gases escape into the atmosphere resulting in air pollution, which is a large contributor to global warming. Air pollution also causes pulmonary diseases, allergies and may even lead to human death. It can also cause harm to other living organisms such as animals and food crops. Thus, mandating the reduction of sulfur in organosulfur compounds in fuel to <10 ppmS by the environmental protection agency. Several studies have been conducted to remove sulfur from fuels, most of which have focused on removing refractory sulfur compounds due to the difficulty in removing sulfur in these compounds. However, the currently employed hydrodesulfurization (HDS) catalysts suffer in producing fuels complying with the future standards of fuels quality. Generally, HDS catalysts are made up of metallic components, Co (Ni) and Mo (W), on porous supports, the catalytic activity of these catalysts strongly depends on the amount of NiWS (CoMoS) phases in it and to the extent in which these phases are exposed on the catalyst support surfaces and this is engineered using chelating agents and size of catalysts. To this end, nanosized materials (nanocatalysts) are considered most suitable, as reported active phases of HDS catalysts are exposed, hence improving the hydrodesulfurization of sulfur-containing compounds in fuels. Nanocatalysts results in nanoparticles and when impregnated on a support will results in high surface area, and enhances electronic property, which increases the activity of the catalyst allowing the most refractory sulfur to be removed. The addition of chelating agents such as EDTA, acetic acid, and citric acid further improves the activity of the catalysts by producing more active phases on the catalyst. In this research project, nanocatalysts will be synthesised using mixed metals with and without chelating agents and tested for HDS activity and selectivity towards sulfur using refractory organosulfur compounds in fuels under industrial HDS conditions. This work was divided into two sections, and this dissertation summarizes the research outcomes of each phase. The first section examines the effect of chelating ligands, namely, ethylenediaminetetraacetic acid (EDTA), citric acid (CA), and acetic acid (AA), on CoMo HDS activity and the sulfidation mechanism. In this study, chelating ligands seem to have a beneficial effect on HDS activity. Detailed mechanistic aspects of interactions between chelating ligands and metallic species (Co-chelating ligands) were also studied. Characterization by SC-XRD revealed that the presence of the chelating ligand result in the formation of complex with cobalt, and the effect of this complex was shown by TG-DSC analysis.

- Description: The purpose of this study was to establish the extent to which the provision of social housing can be enhanced through public-private partnerships (PPPs) in the Buffalo City Municipality. A total quality management approach was used as a foundation to understand the application of PPPs in social housing delivery in the Buffalo City Municipality. The study was desktop research to understand the role of PPPs in the provision of social housing. The findings of the study revealed that PPPs provide additional capital for social housing development. The study highlighted that PPPs play a crucial role in providing alternative management and implementation skills as well as offering greater efficiency in the utilisation of financial resources in the delivery of social housing. The findings of the study further revealed that PPPs accelerate social housing delivery through the provision of additional sources of finance where the government is unable to increase public debt to meet investment needs. The study also identified a plethora of constraints that can hinder the adoption of PPP initiatives in social housing delivery. These include capacity constraints, financial constraints, lack of access to land and an unfavourable policy environment. Subsequently, the study advanced a set of recommendations in this regard that includes the creation of transparent and competitive procurement processes, government support in terms of financial incentives, review of the regulatory framework to improve access to land and the regulation of financial services institutions for access to affordable housing credit. , Thesis (MA) -- Faculty of Humanities, Department of Public Management and Leadership , 2021

- Description: Entrepreneurship has been gathering increasing attention because of its critical impact on the economy. This is due to Entrepreneurship serving both as an engine driving economic growth and as a strategy, which promotes the discovery, dissemination and implementation of innovation. In South Africa, limited research has been conducted to test the entrepreneurial intentions of employees working in the State Owned Enterprises (SOEs). SOEs such as Eskom are facing significant political, institutional and normative pressures which minimise its ability to perform its mandate. Eskom has a surplus work force with a headcount of 47 600 employees, this is 15 000 more than the headcount it had a decade ago, while the electricity production has not changed. The aim of this study is to examine entrepreneurial intentions of Eskom employees and the factors that influence individuals to select employment in the public sector. The entrepreneurial intention model used in this study draws from the work by Mhlanga (2019). The model consists of culture, family obligations, job security, role modelling, entrepreneurial self – efficacy, access to financial resources and locus of control to entrepreneurial intentions. Convenience sampling was used in this study (n=160). The research design involved a cross-sectional approach. SPSS and STATA statistical software were used for the analyses. Job security, role modelling and selfefficacy were found to influence entrepreneurial intentions of Eskom employees in the Eastern Cape. Eskom employees in the Eastern Cape were found to be optimistic about the availability of financing and accessibility for start-ups business ventures. One of the recommendations therefore is for Eskom management to facilitate initiatives such as Entrepreneurship Workshops for Eskom employees to network and share ideas, with funders and mentors. The target population consist of 2050 employees sample size of 160 respondents was obtained. , Thesis (MBA) -- Faculty of Business and Economic Sciences, NNU Business School, 2021
