- Description: The furniture manufacturing industry in South Africa is facing several challenges that affect the performance of firms in this sector. A literature review indicates several factors such as availability of resources; location; access to local markets; access to export markets; and development programmes that may affect the performance of wooden furniture manufacturing firms in the Southern Cape. The purpose of the current study was to fill the knowledge gap on why the performance of wooden furniture manufacturing firms in the Southern Cape has declined. The study intends to contribute to the limited formal information resources on the Southern Cape furniture manufacturing industry. A conceptual framework was developed and employed for investigating factors hypothesised to affect the performance of furniture manufacturing firms in the Southern Cape. The research conducted was explorative. An interpretive paradigm was selected to collect and interpret qualitative data and a positivist paradigm was used for the quantitative component of the study. The quantitative data was subjected to a chi-square test using IBM SPSS statistics software and qualitative data was analysed for meanings and context using ATLAS.ti software. Statistical tests on qualitative and quantitative data were conducted to determine whether sufficient evidence existed to make conclusions on the hypotheses, relating to significant relationships between the selected independent variables for the study and the performance of wooden furniture manufacturing firms in the Southern Cape. The results show that existing development programmes and availability of resources, namely: timber, skilled human resources and availability of finance, influence the performance of furniture manufacturing firms in the Southern Cape. Results further reveal that location; access to local market; and access to export market have a partial influence on the performance of the furniture manufacturing firms in the Southern Cape. The study presents information which serves to improve the capacity for growth of wooden furniture manufacturing firms. Based on the results, recommendations were made to overcome the factors affecting the performance of the furniture manufacturing firms in the Southern Cape. , Thesis (MSc) -- Faculty of Science, School of Natural Resource Management, 2021

- Description: Cryptococcus neoformans is responsible for cryptococcal infections, which have become a great concern particularly in immunocompromised patients. This pulmonary disease causes damage to lung tissue and is presumed to be responsible for approximately 650,000 deaths annually. There is a major need for novel antimicrobial agents to avoid the emergence of resistant strains due to extended use of known antifungal drugs. Silver has become an important antimicrobial agent used in medical devices, cosmetics and even house-hold or clothing products. It is highly toxic and has a reduced risk of resistance. Silver nanoparticles have been broadly explored as an antimicrobial agent due to its high reactivity, large surface area and small size. They have been reported to display antimicrobial activity towards bacteria, viruses and fungi. C. neoformans is a pathogenic microorganism that possesses a number of virulence factors which increases the infectivity of the microorganism in immunocompromised individuals. Some of these include the presence of a polysaccharide capsule, melanin, urease and phospholipase production. Owing to limited availability of antifungal drugs and the possibility of drug resistance, this study focused on an alternative antimicrobial agent, namely silver nanoparticles, and the effects that silver nanoparticles had on fungal β-glucan, chitin and urease, phospholipase and melanin virulence factors. Results from our study show that silver nanoparticles inhibited the growth of C. neoformans at concentrations between 3.125 ƒM and 25 ƒM. Both 26.4 nm and 28.4 nm nanoparticles displayed growth inhibition, but were unable to kill the organism at concentrations of 200 ƒM and above. The silver nanoparticles caused a reduction in βglucan content. There was also an accumulation of intracellular ROS, and phospholipase activity, was reduced. In contrast, the organism displayed an increase in chitin content, melanin and urease activity upon exposure to the nanoparticles. This study shows that chemically synthesized silver nanoparticles are an effective antifungal alternative that greatly reduces or inhibits C. neoformans growth at very low concentrations (ƒM). For future studies it may be feasible to investigate the use of these nanoparticles in combination with known antifungal agents, to prevent the emergence of resistance and inhibit possible defense mechanisms displayed by the organism. , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2021

- Description: Coryogalops sordidus(Epaulette goby), is a cryptobenthic species of the Family Gobiidae that iscommonly foundoccupying turbulent surf zones, calm rock pools, and sand and mud flats, where they are generally carnivorous predators. The distribution of C. sordidushas been recorded for Kenya, Tanzania, Mozambique, and South Africa. The species is also resident in the microbialite pools on the temperate south east coast of South Africa. Recent reports indicated these gobies to be covered in numerous dark lesions, possibly suggesting that the microbialite pools are a sub-optimal habitat. Preliminary analyses have indicated that the dark lesions are a result of encysted metacercaria of a digenetic trematode (fluke). There werehowever,no current recorded parasiticspecies occurring within microbialite pool nor any records of any parasitic species utilizingC. sordidus as a host in South Africa. Therefore, the aim of this study was to investigate parasite-host interactions and parasite presence in and around themicrobialite pool systems of Algoa Bay using C. sordidusas a study species. Coryogalops sordiduswas identified to be parasitised by digenetic trematode metacercaria of the Family Diplostomidae Poirier, 1886, localised primarily to the host musculature, fins, eyes, and integument with no settlement on any of the visceral organs. Furthermore, C. sordidus was found additionally parasitised by a green leech (Class: Hirundinea) of the Family Piscicolidae Johnston, 1865, localised exclusively to the ventral body surface, underneath the pelvic fin of the host. Further investigation into the life cycle of the trematode, suggested that the most probable final hosts wereherons,namely Ardea cinereaand Egretta garzetta garzetta, and intermediate host likely being the freshwater gastropod Assimineacf.capensis, present inthe upper microbialite pools. In both the microbialite and neighbouring rock pools trematode prevalence was found to oscillate in response to seasonal chemical and climatic conditions, whereas the secondary piscicolid leech parasite was influencedmoreby host presence than environmental conditions. Greater prevalence and intensity were measured in the microbialite pools suggesting that these systems likely contained a suit of favourable conditions that allowed for greater trematode loads to be maintained as compared to neighbouring rock pools. As parasites often have deleterious effects on their hosts, the response can manifest as an altered host behaviour or an increased energetic debt due to elevated immune response activity and the associated cost of tissue repair at sites of parasite aggregation.This study further investigatedifgobies (C. sordidus) infected with metacercarial cysts display higher metabolic ratesordifferent swimming behaviour compared to non-infected individuals. The results indicated that the metacercarial load carried by infected hosts had on average no significant impact on energetics, swimming ability, or swimming behaviour, concluding that the average metacercarial intensity present on the gobies is therefore below the threshold of an altered host response. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2021

- Description: A method to map seafloor substrates using machine learning, based primarily on hydroacoustic data including multibeam bathymetry, backscatter, and side-scan sonar, has been developed. The aim was to produce a customdesigned benthic habitat classification method that digitally integrates marine geophysics and biological science data, with relevance to all elements of the local substrate, and this was the first time it was attempted in a South African context. The algorithm developed is able to produce bio-physical benthic habitat maps and this can be extended along the continental shelf of South Africa as new data setsare collected and the algorithm is supplemented. At the outset, this work has focused on broad categories of rock and detailed categories of sediment. Four study sites with varying substrate were selected to holistically build the algorithm that followed a tiered approach of machine learning: Table Bay, Clifton, Koeberg Harbour and Cape St Francis. Table Bay was used to develop a new method of physical seafloor classification, by comparing and contrasting a number of statistical algorithms and software programs. Clifton was used to test the developed clustering algorithm, and Koeberg which is 35 km to the north was used to validate the algorithm because sediment samples, along with drop camera footage, were integrated to better define the results. The resultant verified algorithm was tested at Cape St Francis, where Remotely Operated Vehicle (ROV) footage was acquired in addition to hydroacoustic data. In the first phase of the process towards developing an algorithm, a customised tool was created within ArcGIS using python scripting language to classify seafloor bathymetry, which can be applied to any area of seafloor whatsoever. The tool was based on pioneering work done by the National Oceanic and Atmospheric Administration (NOAA) on a benthic terrain modelling toolbox and adapted to include side-scan sonar data. In the second phase of work, multibeam bathymetry, backscatter and side-scan sonar data that were processed using Qimera, Fledermaus Geocoder Toolbox, and Navlog processing software, were classified using different machine learning techniques including Decision Trees, Random Forests, and k-means clustering computer algorithms. The results from these algorithms were compared to manually-digitised polygons which were created to classify the seafloor substrate distribution by identification of different textures. Integrating all results facilitated a quantitative comparison that illuminated advantages and disadvantages of each machine learning technique and ultimately the k-means clustering techniques were found to be the simplest to implement and understand and worked most efficiently based on their seafloor segmentation capabilities in Table Bay, against all three hydroacoustic data sets (multibeam bathymetry, backscatter and side-scan sonar). In the third phase of work, ground-truthed seafloor characterisation maps were produced for the two study areas of Clifton and Koeberg Harbour. This applied multibeam bathymetry and backscatter data that were collected and processed with machine learning clustering techniques. , Thesis (MSc) -- Faculty of Science, Ocean Sciences, 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: Smart Factories are a key component of Industry 4.0 and have over the last few years become a relevant topic in manufacturing across all industries. The dairy industry is no different and many of the leading dairy manufacturers have adopted many Smart Factory components and technologies. These Smart Factory components and technologies have led to change in the workplace compared to the traditional way of manufacturing. With any organisational change, it is important to consider the impact that it has on the employees of the organisations and what their attitudes and perceptions towards these changes are. When understanding employees’ attitude and perceptions of changes or factors with regard to technological changes in the workplace, organisations can manage and improve the adoption of Smart Factory Adoption. There is limited research on Smart Factory adoption in the dairy manufacturing industry in South Africa. A conceptual model was proposed based on a literature study, identifying the main factors that influence the adoption of a Smart Dairy Factory. A hypothesised model was tested by conducting a research study with a sample of employees from different hierarchical levels in a dairy factory. The questionnaire was distributed to employees and management in the organisation. The results and insights obtained, determined the factors that influence the adoption of a Smart Dairy Factory in South Africa. This study identified that the independent factors of Individual Factors, Job Security, Perceived Benefits, Trust, Company Culture towards new innovations/technologies, Company Culture with employee involvement towards new innovation/technologies, Cost and Resources, Employee perceived value of Skills and Training and Organisational Skills and Training development all have a significant positive effect on Smart Dairy Adoption. The study further identified that the Job Level of employees have a significant effect on all of the factors influencing the Smart Dairy Adoption. This is a significant finding due to the fact that management, in general, is responsible for implementing Smart Factory technologies, whereas the general workforce are the ones accepting and being affected most by the change. , Thesis (MBA) -- Faculty of Business and Economic Sciences, NMU Business School, 2021

- Description: The current unemployment rate in South Africa is sitting at 30%. The South African government has identified various ways of combating this high rate. Entrepreneurship has been identified as one of the tools that can be utilised by the country to assist bring down these high levels. However, it seems that even though this is the case, there has been a decline in the sustainability of entrepreneurship. As per the GEM 2018 report on entrepreneurial activity in South Africa in the age group 25 – 34 years, there has been a downward trend as it has increased back from the low 2016 levels of 6.3% to 14.5% in 2017. The study aims to explore variables that can assist to develop entrepreneurship in South Africa, thereby assisting with its sustainability. Once entrepreneurship is sustainable it can assist with creating job opportunities thereby decreasing the high levels of unemployment in the country. The study starts by asking several research questions that introduce the various variables were identified that have an impact on the development of entrepreneurship. The variables that have been identified are the following: education, national and business culture, support, business skills and competencies. The study uses these variables to investigate the path leading to entrepreneurship development in the country. A qualitative research methodology has been used to carry out the research. Participants from the Eastern Cape, East London area are identified as a sample with which to conduct interviews and collect data. , Thesis (MA) -- Faculty of Business and Economic Sciences, NMU Business School, 2021

- Description: Remand detainees make up a considerable amount of the total prison population in South Africa’s correctional system. Inmates are considered a vulnerable group in our society and the majority have suffered unfavourable life circumstances. Correctional centres are not open establishments and the public is not always aware of the human rights violations that occur in these establishments. The crime rate in South Africa is high and effective means must be taken to ensure the safety of its citizens. Time spent on remand is not viewed as punishment, however it is often met with appalling conditions including severe overcrowding, violence, gangsterism, drug usage, illness, the spread of disease and inadequate infrastructure and resources. This is the reality despite South Africa having one of the most progressive Bill of Rights in the world which guarantees human rights and in addition having a comprehensive Correctional Services legislative framework. Remand detainees are entitled to all rights and protections save for those legally restricted for the purpose of their detention. The court process to determine guilt or innocence is riddled with delays and clogged court rolls which sees matters taking a long time to finalise with time spent on remand regarded as dead time with no opportunities for productive activity. The Canadian position regarding remand detainees was investigated and many similarities were detected with the conditions experienced on remand detention in South Africa. It was found that these challenges are a global issue. This study investigates methods for improvement to the South African remand detainee landscape and highlights reforms that can be undertaken to make South Africa a leader in this arena. , Thesis (LLM) -- Faculty of Law, Criminal and Procedural Law, 2021

- 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: Understanding the variations in structure and abundance of animals and what leads to their distribution within the landscape has captured the attention of ecologists for centuries. Importantly, knowledge of current behaviour of large mammals can be used to inform historic population dynamics and is essential to understanding how early humans used large mammals as a foraging resource. Central to this thesis and improving our understanding of large herbivores is the Palaeo-Agulhas Plain (PAP) where large mammalian herbivores formed a key food resource for early humans. The PAP, now submerged off the southern Cape of South Africa, formed a novel ecosystem during lower sea levels. Characterised by large expanses of nutrient rich grasslands and large grazing herbivores, the PAP stands in stark contrast to the nutrient poor fynbos ecosystems that is in the southern Cape today. In this thesis I focus on the Last Glacial Maximum (LGM; ~20 ka) when the PAP was last fully exposed to answer questions relating to the habitat use and range distribution of large herbivores. Importantly, through the Paleoscape Project, modelled climate, soil and vegetation have made these recreations of large mammals possible. Using modelled climate and vegetation this thesis aims to model the large herbivore communities and understand the influence of early humans on the PAP during the LGM for successful integration into the PaleoscapeABM (the PAP agent-based model). To improve our understanding of large mammals on the PAP I identified five large herbivores that became extinct on the PAP since the LGM and modelled their behavioural and physical traits using k-Nearest Neighbour imputation. I predicted the biomass of large herbivores across the PAP using actual biomass of large herbivores from 39 protected areas across South Africa (spanning five functional groups to include the extinct species) across a rainfall gradient and different biomes. The distribution of large herbivores would likely have been driven by similar top-down and bottom-up drivers we see in large herbivore ecology today. Knowing this, I created a predictive model for large mammals by predicting the probability of occurrence of functional groups of large herbivores in relation to environmental drivers and humans. Results showed that all species (except Antidorcas australis) were adapted to the grassy environment of the PAP and these specialisations likely contributed to their extinction along with changing climates and intensified hunting from humans. When predicting herbivore viii biomass, biome was the most important factor influencing the relationship between herbivores and rainfall. In general, large herbivore biomass increased with rainfall across biomes, except for grassland. Finally, I showed the probability of occurrence of large herbivores was influenced by early humans, water availability and a landscape of fear on the PAP. Through this thesis I have successfully provided detailed accounts of the biomass and probability of occurrence of large herbivores on the PAP. Importantly, this information can be seamlessly integrated into the PaleoscapeABM. Finally, I highlight the importance of this knowledge in understanding early humans, the potential shortcomings of this study and resulting areas where research needs to be focused. , Thesis (PhD) -- Faculty of Science, School of Natural Resource Management, 2021

- Description: Series of compounds were screened using Schrodinger suite (Maestro). The DFT calculations were used for geometry optimization of the ligands using the B3YLYP functional and 6-31G basis set, and these structures were used for docking studies. Maestro was used to predict the activity of thiazole derivatives against HIV-1 protease. The range of estimated inhibition constants for these thiazole derivatives (65 nM-5 μM) indicate moderate to weak activity against HIV-1 protease, given that the activity of current protease inhibitors is typically found have experimental inhibition constants around 0.1-2.0 nM. Twenty compounds were selected based on the docking results and they were synthesized and characterized by NMR, FT-IR and elemental analysis. The cytotoxicity studies were done at two different concentrations (100 μM and 10 μM), using the brine shrimp bioassay. All compounds were highly toxic at 100 μM, with the percentage mortality between 20 to 75%. Eight compounds were selected for the enzyme bioassay based on the results obtained from lower concentration (10 μM). In the enzyme inhibition studies, the profile of HIV-1 activity was done at different inhibitor concentrations (800 μM – 10 μM) by measuring the cleavage of the synthetic substrate (Abz-Thr-lle-PNO2Phe=Gln-Arg-NH2) at excitation wavelength of 345/490 nm using fluorescence. Ligands 5 (unsubstituted derivative), 7 (4-nitro derivative) and 16 (4-methoxy derivative) gave percentage inhibition of 39, 45 and 42%, and this activity was very low compared to the activity of the positive control ritonavir (85% enzyme inhibition). Ligands 8 (4-methoxy derivative) and 12 (4-methoxy derivative) gave enzyme inhibition of 70% and 75%. These results suggest that the presence of the methoxy substituents ii increases activity of these compounds against HIV-1 protease. Most of the compounds gave good IC50 values between 12.5-42.7 nM. The bromo-substituted ligand 7 gave the lowest IC50 (12.5 nM). Ligand 11 also gave a good IC50 value of 14.86 nM. The bromo-substituted derivatives showed to be very active compared to other types of thiazole derivatives. Enzyme kinetics were carried out to compare the inhibition constants obtained via computational modelling. Ligand 7 (4-methoxy derivatives) binds better in the active site of HIV-1 protease than other compounds in Class B, with Ki = 50 nM, Km = 23.8 Nm and Vmax = 83.3 nM/min. The unsubstituted (L5), 4-bromo (L7) and 4-nitro (L8) substituted compounds gave inhibition constants of 100 to 112 nM. The in vitro testing yielded higher activity than that determined in silico. , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2021

- Description: Large carnivores play a vital role in ecosystems, providing ecosystem services such as herbivore regulation. If not properly monitored, carnivores could place significant pressure on certain prey species, and in extreme cases, result in the local extinction of certain species. A lack of demographic data can indirectly threaten carnivores, as policies and management decisions based on demographic data can result in the over harvesting or unsustainable hunting of large carnivores. Furthermore, their conservation is becoming confined to small, fenced, protected areas. Whereby species are intensively managed, making demographic and ecological data a fundamental part of conservation decisions. Therefore, it is essential for conservation practitioners to understand large carnivore demography and their role, to conserve them effectively. To provide Madikwe Game Reserve with the necessary data for effective long-term monitoring and management of the large carnivore guild, I estimated the population size of the cryptic carnivores. I then investigated the efficacy of different camera trap survey designs on improving the detection probability of leopard (Panthera pardus), brown hyaena (Parahyaena brunnea), and spotted hyaena (Crocuta crocuta). I found that brown hyaena and spotted hyaena detection probability increased with a higher number of camera traps, whereas leopard detection probability did not increase with an increased number of camera traps. I further investigated the diet, prey preferences and dietary overlap of lion (Panthera leo), cheetah (Acinonyx jubatus), African wild dog (Lycaon pictus), leopard, spotted hyaena and brown hyaena.

This iv information will assist MGR to make informed decisions about large carnivore management in the reserve.

- Description: Large carnivores play a vital role in ecosystems, providing ecosystem services such as herbivore regulation. If not properly monitored, carnivores could place significant pressure on certain prey species, and in extreme cases, result in the local extinction of certain species. A lack of demographic data can indirectly threaten carnivores, as policies and management decisions based on demographic data can result in the over harvesting or unsustainable hunting of large carnivores. Furthermore, their conservation is becoming confined to small, fenced, protected areas. Whereby species are intensively managed, making demographic and ecological data a fundamental part of conservation decisions. Therefore, it is essential for conservation practitioners to understand large carnivore demography and their role, to conserve them effectively. To provide Madikwe Game Reserve with the necessary data for effective long-term monitoring and management of the large carnivore guild, I estimated the population size of the cryptic carnivores. I then investigated the efficacy of different camera trap survey designs on improving the detection probability of leopard (Panthera pardus), brown hyaena (Parahyaena brunnea), and spotted hyaena (Crocuta crocuta). I found that brown hyaena and spotted hyaena detection probability increased with a higher number of camera traps, whereas leopard detection probability did not increase with an increased number of camera traps. I further investigated the diet, prey preferences and dietary overlap of lion (Panthera leo), cheetah (Acinonyx jubatus), African wild dog (Lycaon pictus), leopard, spotted hyaena and brown hyaena. I found that all species displayed a degree of dietary overlap, however the most notable level of competition occurred between leopards, wild dogs, and cheetahs. This iv information will assist MGR to make informed decisions about large carnivore management in the reserve. I recommend continued long-term monitoring for the establishment of trends over time, allowing for holistic management of the entire large carnivore guild. , Thesis (MSc) -- Faculty of Science, School of Natural Resource Management, 2021

- Description: The concept of internationalisation of higher education is a dynamic process, continuously shaped and reshaped by the international context in which it occurs. While the topic of internationalisation has been explored, internationalisation at the Nelson Mandela University Business School has not been investigated. This study will attempt to determine the Nelson Mandela University Business School’s internationalisation. This study used literature reviews to investigate the definition and elements of internationalisation. The literature review facilitated the creation of a conceptual model for internationalisation. The network theory and the social exchange theory informed the theoretical basis of this study. This research pursues a positivistic approach using quantitative methods of analysis. Accordingly, the conceptual model was tested using Likert scale data and statistical analysis. This study surveyed current and former Nelson Mandela University Business School students This study established that the independent factors of International Affiliation, African Collaboration, Research, Curriculum, Field trips, Benefits, Risks and COVID-19 were all found to exert a significant positive effect on Internationalisation. An Exploratory Factor Analysis was conducted to explore the relationships among factors and to identify any possible patterns in the factor relationships. All these factors (except for African Collaboration and Field trips) demonstrated positive correlations with Internationalisation. In this study, the statistical data, relating to these factors helped to establish the hypothesised model for Internationalisation at Nelson Mandela University Business School. The data are established as a baseline, which allows for comparisons to be made between surveys at similar higher education institutions. Internationalisation requires additional research to refine and test its suitability and validity to test internationalisation. This study further makes contribution to the network theory as well as to the social exchange theory as the findings support these theories. , Thesis (MBA) -- Faculty of Business and Economic Sciences, NMU Business School, 2021

- Description: Human impacts have altered natural ecosystems which required species to become resilient in order to survive the anthropogenic landscape. The study area is located in the highly fragmented Overberg area in the Western Cape of South Africa. The high degree of fragmentation of the area is as a result of the nutrient rich soils and favourable topography which makes the area highly suitable for agricultural practices. The agriculture practiced in the area is mainly grain crops and livestock farming and the remaining patches of natural vegetation consist of Fynbos and Renosterveld vegetation. The patches of Fynbos and Renosterveld vegetation acts as movement corridors to allow species movement through the anthropogenic landscape. The anthropogenic landscape requires species to be resilient and to adapt to a novel habitat which poses new threats as well as new resources. The aim of the study is to investigate the effect of landscape transformation, resulting from agricultural practices, on the feeding and behavioural dynamics of five small specialist browser species in a fragmented lowland Fynbos and Renosterveld system. The objectives were to determine the forage preferences of each of the five specialist browser species and to determine which site-specific characteristics, drive the seasonal habitat use of the five specialist browser species. The five specialist browser species were bushbuck (Tragelaphus sylvaticus), Cape grysbok (Rhaphicerus melanotis), common duiker (Sylvicapra grimmia), grey rhebok (Pelea capreolus) and steenbok (Rhaphicerus campestris). To determine the dietary selection of the five specialist browser species we collected dung samples and performed a histological analysis on the dung samples. To determine the habitat use of the five specialist browser species we used an occupancy analysis framework on camera trap data collected on each of the species. Some species appeared more dependent on the food resources from the anthropogenic landscape and spent more time in the crops but required close by cover of natural vegetation. Others appeared more dependent on the remaining pockets of natural vegetation for food resources and spent more time in the natural vegetation. These species would occasionally move into the crops to utilise the food resources. Both the anthropogenic as well as the natural landscape contributed to the diets of all of the species. These species have been resilient to changes in the landscape and appear to be benefiting from the resources presented in the novel landscape. , Thesis (MSc) -- Faculty of Science, School of Natural Resource Management, 2021

- Description: Phase change materials (PCMs) have been incorporated into clothing and textiles to provide added value in terms of thermoregulation and thus added comfort to the wearer in extreme weather conditions and sporting activities. Since clothing is laundered many times during the service life of the textile, the effects of simulated domestic laundering on the physical and thermal properties of a non-woven textile which contains PCMs were investigated. The thermal properties, such as the thermal degradation, melting, evaporation and crystallisation were measured by the TGA and DSC analytical techniques. The physical properties, such as the microcapsule size distribution, and the microcapsule morphologies of the PCM microcapsules, were measured by the SEM and Raman analytical techniques. The main objectives of this study were to determine the effect of repeated laundering at different wash temperatures on the mass loss, enthalpy, and physical changes in PCM. Thermal degradation as determined by TGA thermograms was found to be higher at a wash temperature of 60°C relative to that of a wash temperature at 30°C, the mass loss being 4.6% more at 60°C than at 30°C. This was asserted to physical changes such as size and shape of the PCM microcapsules as evident in SEM images. The SEM images showed broken and collapsed PCM microcapsules in the web and around the fibre, indicating evaporation of the thermoregulating content of the PCM. It was found that the heat capacity of the sample washed at 60°C was much lower than that of the unwashed sample, the difference being approximately 50% in terms of the latent heat capacity as determined by DSC thermograms. This implies that the latent heat effectiveness of the PCM has decreased significantly. The physical properties of the PCM such as the intermolecular interaction, the intensity and width of peaks, polarisation, degree of crystallinity and the orientation changed as illustrated in the Raman analysis. , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2021

- Description: The thesis presents a framework to integrate social entrepreneurship (SE) into development planning in South Africa. Even though there is no consensus on a universally accepted definition of the term, there is concurrence that SE brings about social change that can influence the overall development of the community. In South Africa, SE is thus conceived of as one of the mechanisms for addressing the wicked and persistent socio-economic challenges that face the country. Social entrepreneurship occurs in areas such as education, health, skills development, youth programmes, rehabilitation, safety, food security, poverty, job creation, human rights activism, environmental issues, arts and culture, among others. However, it remains unclear how SE is integrated into the development planning and implementation processes. Questions of integrating SE into development planning are asked within the context of South Africa as a democratic developmental state that intervenes in the development process. It emphasises the mobilization of and engagement with all sectors towards the achievement of its development objectives as articulated in the national development plan (NDP). Also, government recognizes organizations in the social enterprise sector (such as NPOs and NPCs) as stakeholders and development partners who deliver relevant services towards the achievement of these development objectives. However, there is a lack of framework to mobilize and integrate the social enterprise sector and SE into the development planning process. Social entrepreneurship, therefore, tends to occur in insolation from other development programmes. , Thesis (PhD) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 2021

- Description: South Africa’s uncompetitive freight logistics system is severely hampering the country’s competitiveness and the current disproportionate reliance on the road freight sector is a main contributing factor. The need for a modal shift from road to rail has long been advocated as a necessity to correct this freight logistics imbalance. This study aims to gain a better understanding of the incentives needed to move freight distribution from road to rail within shorter distance corridors and specifically the Port Elizabeth- Gauteng corridor. Specifically, it evaluates the incentives needed, the importance of cost, distance and whether special capabilities are required to achieve such a move. Empirical data were collected with an online survey and distributed via the Road freight Association (RFA) to transport operators and micro operators within South Africa. Statistical analysis was used to analyse the main research and sub-questions through descriptive statistics, multiple regression analysis and Pearson correlation. The results showed that a mostly strong positive correlation exists between the measured variables in this study while also indicating a significant relationship between the independent variables and moving freight distribution from road to rail. These results proved that all the factors are related to each other and that implementing a move of freight from road to rail would need to include the consideration of all these factors. The study concludes that moving freight distribution from road to rail will be possible if incentives regarding cost rebates or subsidies amongst others are taken into account and included in additional future legislation or more practical implementation plans. , Thesis (MBA) -- Faculty of Business and Economic Sciencence, NMU Business School, 2021
