- Description: Third-party logistics (3PL) providers have continued to be key players in the supply chain network and have witnessed a growth in the usage of information technology. This growth has enhanced the volume of structured and unstructured data that is collected at a high velocity, and is of rich variety, sometimes described as “Big Data”. Leaders in the 3PL industry are constantly seeking to effectively and efficiently mature their abilities to exploit this data to gain business value through data-driven decision-making (DDDM). DDDM helps the leaders to reduce the reliance they place on observations and intuition to make crucial business decisions in a volatile business environment. The aim of this research was to develop a prescriptive model for DDDM in 3PLs. The model consists of iterative elements that prescribe guidelines to decision-makers in the 3PL industry on how to adopt DDDM. A literature review of existing theoretical frameworks and models for DDDM was conducted to determine the extent to which they contribute towards DDDM for 3PLs. The Design-Science Research Methodology (DSRM) was followed to address the aim of the research and applied to pragmatically and iteratively develop and evaluate the artefact (the model for DDDM) in the real-world context of a 3PL. The literature findings revealed that the challenges with DDDM in organisations include three main categories of challenges related to data quality, data management, vision and capabilities. Once the challenges with DDDM were established, a prescriptive model was designed and developed for DDDM in 3PLs. Qualitative data was collected from semi-structured interviews to gain an understanding of the problems and possible solutions in the real-world context of 3PLs. An As-Is Analysis in the real-world case 3PL company confirmed the challenges identified in literature, and that data is still used in the 3PL company for descriptive and diagnostic analytics to aid with the decision-making processes. This highlights that there is still room for maturity into using data for predictive and prescriptive analytics that will, in turn, improve the decision-making process. An improved second version of the model was demonstrated to the participants (the targeted users), who had the opportunity to evaluate the model. The findings revealed that the model provided clear guidelines on how to make data-driven decisions and that the feedback loop and the data culture aspects highlighted in the design were some of the important features of the model. Some improvements were suggested by participants. A field study of three data analytics tools was conducted to identify the advantages and disadvantages of each as well as to highlight the status of DDDM at the real-world case 3PL. The limitations of the second version of the model, together with the recommendations from the participants were used to inform the improved and revised third version of the model. , Thesis (MSc) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2021

- Description: Riparian vegetation provides an array of various ecosystem functions and has significantly shaped the conditions of catchments. It has strong controls on fluvial geomorphology and erosion processes. The Mgwalana catchment has been intensively studied over the years and the current environmental condition of the study has been linked to land use history. The catchment has been subjected to land use/cover changes (LUCC) over the years. However, spatial variations in riparian vegetation, their implications for stream bank stability and the contribution of land tenure systems to stream channel degradation are poorly understood. The study sought to assess the implications of the spatial variations in riparian vegetation density for stream bank erosion in relation to land tenure on a catchment scale. Land tenure units comprising the catchment of study are traditional and betterment villages (communal lands), and former white commercial farms. A three-pronged approach using GIS and remote sensing, field investigations and laboratory procedures for soil analysis was employed in this study. Variations of riparian vegetation density in the catchment were mapped using ArcGIS for the two land tenure units to assess the spatial variations of riparian density along stream reaches and to determine the spatial relationship between land tenure units and riparian vegetation diminution. Other mapped shape files include sediment accumulation zones to analyse the spatial relationship between riparian vegetation density and sediment sinks. LUCC classification and analysis of the Normalized Difference Vegetation Index (NDVI) were carried out in IDRISI Selva, using Landsat 8 TM imagery of 2018 to represent the current spatial riparian vegetation variations in the catchment. Field investigations were conducted to determine the coupling among hillslope gully erosion, riparian vegetation density and sink areas; and to assess physical characteristics of soil. This would permit an assessment of the implications of riparian vegetation for stream bank erosion and sediment accumulation within the tenure units. Soil samples were taken from scantily and densely vegetated stream reaches, as well as measurements of channel widths and depths. Analyses of soil physical properties viz; grain size distribution, bulk density, soil texture and aggregate stability were done. Results demonstrated that a sparse riparian vegetation distribution was consistent with the communal villages, confined to the upper catchment area. Dense riparian vegetation distribution was consistent with former commercial farms in the lower catchment area. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2021

- Description: This study used a mixed methods approach to provide a systematic review of sustainability reports in South African listed companies that are included in the FTSE/JSE Responsible Investment Index. The purpose was to explore sustainability report content to guide companies of what should be included in such a report. A content analysis schedule was developed to provide the basis for the information to be extracted from the sustainability reports. Three categories, namely, biographical information, reporting format and the theoretical framework were included in the schedule. The sustainability reports of 18 South African JSE SRI Index companies listed on the JSE 2 July 2019 from the mining, retail and investment sectors were included in the sample. The main results showed that the majority of companies in the mining sector used sustainability reports, while nearly half of the companies in the retail sector used sustainability reports. Companies in the investment sector used a variety of reports with a third using integrated reports. Most companies used the JSE listing requirements as their guiding tool in developing their sustainability reports. Environmental issues also seemed to play a major role in sustainability development of a company irrespective of the sector to which it belonged. This systematic review identified the need for a regulator for sustainability reporting and the standardisation of sustainability report content. , Thesis (MCom) -- Faculty of Business and Economic Sciences, 2021

- Description: The concept of a Smart City has evolved over the last three decades and has attracted the increasing interest of the scientific research community. Unfortunately, many Smart City projects and initiatives do not provide the value expected by all the stakeholders. Many of the reasons for this relate to a lack of data management, data integration, data access and stakeholder participation. People are an integral part of any city’s ecosystem, and the Smart City concept was introduced to address the challenges of an ever-growing global population leading to the risk of depletion of economic, environmental and social resources. The problem addressed in this study is based on the challenges preventing the creation of the value of smart cities or stakeholders. Limited research has been published on the status of Smart City initiatives or on the impact of various success factors on the potential value creation for stakeholders including citizens. Studies on initiatives in developing countries, such as South Africa are even less. Whilst some challenges and constraints related to smart cities in Africa have been reported, there are no studies reporting on initiatives across the data value chain that consider all types of stakeholders, nor the impact of these initiatives. This study addressed this gap in research and designed a theoretical Value Alignment Smart City Stakeholder (VASCS) Model based on a Systematic Literature Review and a review of related theories. The model has important components that should form part of any Smart City project or Smart City initiative. These five main components are: 1) nine Smart City dimensions with related success factors; 2) four stakeholder roles (enablers, providers, utilisers and users); 3) the data value chain; and 4) the five phases of stakeholder benefits/value realisation that can be linked to; 5) stakeholder value alignment. This study applied the VASCS Model to Smart City initiatives in two case studies in the Eastern Cape Province of South Africa, which were the Nelson Mandela Bay and Buffalo City to investigate and understand the status of such initiatives and the alignment of value thereof. The stakeholder interviews were conducted in two rounds with various stakeholders of Smart City initiatives, referred to as cases in the two case studies. An expert review of the VASCS Model was conducted with eight experts in the field of Information Systems and Smart Cities. The findings of this review served to confirm the components of the model, with only minor improvements recommended. It was confirmed that all of the components need to be considered in planning Smart City projects. The first round consisted of six interviews with enablers and providers and the second round consisted of 22 interviews with users, utilisers and citizens. The interviews investigated the value and impact experienced by stakeholders of these initiatives, with a particular focus on the users, utilisers and citizens of the cases. The interview data was transcribed and qualitatively analysed by using Atlas.tiand Excel. The data was analysed according to the Technological, Organisational and Environmental theory constructs and other identified themes. The interview analysis findings revealed several drivers for these initiatives, which were primarily cost reduction, integration and quality assurance. The results also highlighted access to resources, such as technical skills as a challenge. Another challenge identified was connectivity related to access to data and the digital and physical divide that can impact decision making. The main benefits of Smart City initiatives highlighted were the provision of infrastructure, education and training and digitalisation. The theoretical contribution of this study is the VASCS Model, which can assist other researchers and practitioners with knowledge of the factors, drivers, challenges and value obtained in Smart City initiatives. The model has two supplementary components: A Stakeholder Classification Model and a Smart City Success Factor Evaluation Template. The practical contribution of this study is the potential use of the VASCS Model by practitioners, city management, researchers and other stakeholders, who can use the model, with the related model and template for planning and evaluating Smart City initiatives. The model can be used to classify the digital activities according to a Smart City’s success factors while evaluating the value created by these activities. The impact of these initiatives can then be assessed through value realisation and alignment for stakeholders. The scientific contribution is the adoption of the model to the cases in the Eastern Cape. To reveal in depth, rich, interview findings that provide important lessons learnt relating to the value created for the stakeholders and the addition of these findings to the body of knowledge. , Thesis (PhD) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2021

- Description: Housing delivery in South Africa is a crucial and topical issue affecting many citizens. The primary objective of the study was to determine the role of administrative justice in the implementation of the Reconstructive and Development Programme (RDP) in Berlin Town, in the province of the Eastern Cape in South Africa. In addition, the aim of this study was to explore the challenges of RDP housing in the study area, as a way of probing whether housing needs were being met. The study was conducted using a qualitative research methodology in gathering data from Berlin Town residents, Buffalo City Metropolitan Municipality staff and Berlin Town councillors. The data analysis revealed that respondents affirmed the importance of administrative justice and the effective implementation of the RDP with regard to housing. Based on the findings of the study, the researcher recommends that the Buffalo City Metropolitan Municipality prioritise the full implementation of the Integrated Development Plan (IDP) in dealing with the housing backlog and challenges in Berlin Town. Moreover, the findings of this study revealed that it is possible to highlight specific recommendations that can be used by various other local municipalities. Thus, the research study showed that efficient local municipal operations have a direct impact on the delivery of RDP houses. Relating to ethical considerations, the researcher ensured that all the requirements for credible research were met throughout the study. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2021

- Description: The role that is played by Non-Governmental Organisations in aiding development initiatives can never be overemphasised. These organisations have partnered with numerous States, mostly in developing countries, in spearheading, facilitating, and evaluating various development programmes. Yet, they face daunting futures as their constant reliability on donor funds has affected their sustainability. To this end, their efforts in addressing social, economic, and even political challenges in a sustainable manner is greatly compromised. This research seeks to assess the financial sustainability of local NGOs with Thandusana as a case study. It further explores factors other than funding that influences an organisation's financial sustainability. These factors are income diversification, sound financial management practices, good donor relationships and own income generation. The research concurred with many other scholars that local non-governmental organisations in South Africa are financially unsustainable and are dependent on donor funds, and Thandusana is no exception. After having found out that Thandusana is not geared to create its own income-generating activities, the research concludes by recommending that the governing board establish structures that commit funds for profit-making ventures which are in turn used to sponsor their non-profit functions but caution should be exercised lest they abandon their missions for profit-making. This study employed a qualitative research approach and is based on an interpretive paradigm. The research used a descriptive case study design. Data was collected using document compilation while document analysis was the data analysis tool. Non-probability sampling was used in selecting the sample that was used. , Thesis (MADS) -- Faculty of Business and Economic Sciences, 2021

- Description: Web-based technologies have fostered an online environment where information can be disseminated in a fast and cost-effective manner whilst targeting large and diverse audiences. Unfortunately, the rise and evolution of web-based technologies have also created an environment where false information, commonly referred to as “fake news”, spreads rapidly. The effects of this spread can be catastrophic. Finding solutions to the problem of fake news is complicated for a myriad of reasons, such as: what is defined as fake news, the lack of quality datasets available to researchers, the topics covered in such data, and the fact that datasets exist in a variety of languages. The effects of false information dissemination can result in reputational damage, financial damage to affected brands, and ultimately, misinformed online news readers who can make misinformed decisions. The objective of the study is to propose a set of guidelines that can be used by other system developers to implement misinformation detection tools and systems. The guidelines are constructed using findings from the experimentation phase of the project and information uncovered in the literature review conducted as part of the study. A selection of machine and deep learning approaches are examined to test the applicability of cues that could separate fake online articles from real online news articles. Key performance metrics such as precision, recall, accuracy, F1-score, and ROC are used to measure the performance of the selected machine learning and deep learning models. To demonstrate the practicality of the guidelines and allow for reproducibility of the research, each guideline provides background information relating to the identified problem, a solution to the problem through pseudocode, code excerpts using the Python programming language, and points of consideration that may assist with the implementation. , Thesis (MA) --Faculty of Engineering, the Built Environment, and Technology, 2021

Finding solutions to the problem of fake news is complicated for a myriad of reasons, such as: what is defined as fake news, the lack of quality datasets available to researchers, the topics covered in such data, and the fact that datasets exist in a variety of languages. The effects of false information dissemination can result in reputational damage, financial damage to affected brands, and ultimately, misinformed online news readers who can make misinformed decisions. The objective of the study is to propose a set of guidelines that can be used by other system developers to implement misinformation detection tools and systems. The guidelines are constructed using findings from the experimentation phase of the project and information uncovered in the literature review conducted as part of the study. A selection of machine and deep learning approaches are examined to test the applicability of cues that could separate fake online articles from real online news articles. Key performance metrics such as precision, recall, accuracy, F1-score, and ROC are used to measure the performance of the selected machine learning and deep learning models. To demonstrate the practicality of the guidelines and allow for reproducibility of the research, each guideline provides background information relating to the identified problem, a solution to the problem through pseudocode, code excerpts using the Python programming language, and points of consideration that may assist with the implementation. , Thesis (MA) --Faculty of Engineering, the Built Environment, and Technology, 2021

- Description: Corporate governance is regarded as a system by which an organisation is directed and controlled and it is concerned with structures and responsibilities within organisations. Public entities’ corporate governance is a concept that is gaining more interest, both in specialized literature and in practice. Corporate governance practices are not standard across countries and this dissimilarity is a result of diverse legal structures and cultural settings adopted by different states and provinces. The Eastern Cape Public Entities (ECPEs) have an important role to play in pursuing the economic, social and developmental state agenda. The EC province has ten (10) public entities with mandates and enabling legislations to enhance the provincial economic development, growth and sustainability issues. Of the ten (10) public entities, one entity was used for pilot study. Furthermore, one public entity decided to withdraw from the study, as it was voluntary to participate and that resulted in eight public entities participating. In terms of the questionnaire returns, forty-four (44) responses were received from eight (8) public entities. The main objective of this study was to investigate selected factors impacting on effective corporate governance of ECPEs. In this study, positivistic research paradigm was utilised by means of quantitative research method. Non-probability sampling was used. Primary data was collected using the survey method by means of structured self-administered questionnaires. The empirical results showed that ethical value, organisational culture and policy regulatory framework had a statistically significant impact on corporate governance of ECPEs; while employee morale, leadership, and role clarification were found not to have a statistically significant impact on corporate governance. The findings of this study are envisaged to assist in ensuring effective governance of public entities in order to encourage accountability, public confidence or trust in the corporate system and to drive public policy. Furthermore, the findings can help public entities to achieve what is expected, in terms of work performance objectives or productivity in accordance with the norms and standards. , Thesis (MCom) -- Faculty of Business and Economic Sciences, 2021

- Description: The conservation industry was closed in the previous apartheid time from the black native people and only opened for the white people alone (Spierenburg & Brooks, 2014). According to Mokotjomela, Nombewu, and Peinke, 2015, the game transformation industry is in need of being transformed to more young black people; they noted the challenges that are faced by the young black people in being able to own nature reserves. These include the fact that they are landless. Secondly, the land transformation that is done through the Department of Rural Development, Land and Agrarian Reform (DRDLAR) is not given back to the rightful owners with the title deeds which is also a challenge as one cannot develop land when there is no certainty that it is theirs (Turner, 2004). Tourism destinations which include the game reserves attract tourists because of the positive economic impacts such as labour-intensive jobs, foreign exchange, and foreign direct investments that come with tourists and boost small businesses. According to Sifilo and Henama (2017), tourism has been an economic messiah of South Africa and the decline of mining jobs has been mitigated by the growth of jobs in the tourism industry. The Eastern Cape's economy is still characterised by disparities in employment rates, income, service levels, and productivity. Economic growth rates have been modest, in line with the rest of the country. Low growth and high unemployment have created considerable issues for the province, with a notably increased demand for social services. According to the most recent economic data, the province's economy is declining (or at the very least is stagnant): The average yearly change in gross domestic product (GDP) per region (Eastern Cape) was 1% in the preceding five years, but only 0.6 percent in the last year The selection of the qualitative research approach and in particular the use of open-ended questionnaires is because it is the only platform that will allow participants to voice their opinions fully without limits and allow the study not to be limited with the information given by the participants. The first section of the questionnaire aimed at obtaining profile data on the respondents. These include age, gender, ethnicity, home language, educational level and time working in conservation and the tourism sector. Questions 8 – 17 focused on respondents stating no, yes, or maybe to the posed questions and elaborating on their experience and knowledge of the wildlife industry, while questions 18 – 24 mainly focused on gaining and listing opinions of respondents on solution to allow entry for black people into the wildlife industry, as well as giving advice on how government and the private sector can assist in reaching the desired goal. Strongly indicated by the empirical results is the gap between the previously disadvantaged group and the white minority group in the province of the Eastern Cape in the wildlife conservation industry. Shown by the results is the position of the black people in the industry as just servants or employees and not owners or equal shareholders and the lack of women leadership in the industry, as well as young people involvement in the decisions and operations of the industry. The list of barriers had one common barrier identified by almost all respondents as noted by the researcher: the issue of land unavailability for the black people in the province. Communal land does not have title deeds as the land is in the hands of governmental departments and traditional authorities. Conditions stipulated on the game transformation policy of the Eastern Cape state that an individual must be in possession of a title deed to the land. This is but a dream to the black people of the Eastern Cape, especially a title deed to a land big enough to be converted into a game reserve. The empirical results strongly indicate the land ownership as the number one barrier for black people from owning game reserves. , Thesis (MBA) -- Faculty of Business and Economic Sciences, 2021

- Description: he thermal decomposition of waste tyres via pyrolysis is considered to be amongst the most promising methods of recycling tyres due to its minimal environmental impact (in terms of reduction in pollution). During pyrolysis, tyres are thermally degraded in an inert environment to produce gas, oil and char. The gas and oil have promising commercialization prospects while the char remains a pollutant despite the strides made in a lot of research to upgrade the char to carbon black, activated carbon and even for reuse as a filler in tyre manufacture. For pyrolysis to be profitable, or worthy of investments, all three of its products (oil, char and gas) need to be valorised. Pyrolysis-derived tyre chars (PT-char) have an energy value equivalent to high rank coals, however, the use of PT char as a solid fuel is uncommon due to the high contents of sulphur and mineral matter as well as low volatile matter content of the PT-char. As such, the combustion of PT-char is characterised by high ignition temperature, low thermal reactivity, and no flame formation due to the low amounts of volatile matter. On the other hand, biomass are clean, renewable feedstock, having low sulphur and mineral matter contents, as well as high thermal reactivity. The blending of PT-char with biomass could potentially improve the combustion properties of PT-char and minimise the release of toxic emissions from the char, and thus, could make PT-char suitable for use as a fuel source. In this study, PT-char was blended with torrefied wood and microalgae biomass to demonstrate the suitability of using PT-char-biomass-fuel blend as an energy feedstock. To this effect, a mixture design of experiments was used to formulate the PT-char biomass blends and regression analysis was employed to select an optimum blend formulation for the combustion and mechanical properties of the blends. Proximate analysis results showed a non-linear increase in the volatile matter and a non-linear decrease in the fixed carbon and ash yield as the biomass ratio increased. The calorific value also increased on an additive basis with increasing biomass proportion. The elemental analysis results showed a decrease in the calcium, zinc and bromine contents and an increase in the potassium and iron contents increased with increasing biomass proportion. Likewise, the sulphur content decreased while the oxygen, hydrogen and nitrogen contents increased with increasing biomass ratio. vi Thus, the fuel properties of the blends improved with increasing biomass ratio and without compromising the calorific value of the PT-char. Moreover, the TG-MS analysis showed that the PT-char and the respective blends did not show any release SO2 up to 650°C. Thus, making the fuel suitable for use in low temperature applications such as household and certain boilers. The results of the regression analysis showed that the blend formulation with the highest proportions of biomass, thus C55-T30-M15, is the optimum blend to produce a solid fuel with a low initial decomposition (214°C) and char ignition temperatures (532°C) as well as maximum burn-out temperature (640°C). In essence, the high thermal reactivity of PT-char is improved when both biomasses are loaded at maximum ratios as per the experimental design. The results of the MS showed a decrease in CO2 and NO2 emissions with increasing biomass proportion. The optimum blend (C55-T30-M15) was found to have a comparably higher gross calorific value (26 MJ/kg), lower sulphur content (1.1 wt.%), low ash yield (11wt.%) and lower concentration of minerals (i.e. zinc) than raw PT-char. In addition, the volatile matter content of the blend (20 wt.%) was found to be higher than that of PT-char and the ignition temperature of the optimum fuel blend was relatively lower and its burnout temperature higher than that of PT char. The MS results revealed that the CO2 and NO2 emissions were higher in the optimum blend than the PT-char. The mechanical properties of the pellets; impact resistance and compressive strength increased with increasing biomass blending ratio and even more so with increasing microalgae ratio. The C55-T30-M15 and C75-T10-M15 were selected as optimum blends using regression analysis and both blends exceeded the benchmark for mechanical properties except for water resistance. The blending did not improve the water resistance and all the blends did not meet the minimum threshold for water resistance. Overall, the blending of PT-char with torrefied wood and microalgae biomass has shown to improve the fuel properties PT-char, and therefore, making it a suitable potential fuel source. , Thesis (MSc) -- Faculty of Science, 2021

- Description: Climate change continues to pose a threat to mankind. Its impacts are evident in both developed and developing countries. South Africa is a no exception to the climate change problems. Climate change in South Africa has affected water availability which subsequently affects food security of the country. This research study investigated the impacts of climate change on food security in South Africa. South Africa’s food security is severely affected by climate change and as a result, the South African government through the Department of Agriculture, Forestry and Fisheries has devised strategies to respond to climate change and ensure food security in the country. The study analysed government documents and articles about climate change from 2008 to 2018. The study employed content analysis as a data analysis method and the study developed eighteen codes and from those codes, four themes emerged. The research findings highlight that South Africa is a food secure nation only at a national level. In addition, the findings highlighted that climate change poses a significant threat on the agricultural sector which ultimately affects food security in South Africa. The climate change impacts in South Africa include an increase in temperatures, rise in sea water levels, and floods. Climate change in South Africa continues to pose a significant threat in the GDP as it affects crop production and livestock farming, which ultimately affects the exports of the country. , Thesis (MA) -- Faculty of Business and Economic Sciences, Economics, Development & Tourism, 2021

- Description: The management and protection of protected areas such as nature reserves remains a primary concern for the different stakeholders involved; especially the marginalised rural communities that are deprived of genuine ownership of the natural resources. The representation of the marginalised rural communities adjacent to the protected areas has become significant in the control and utilisation of natural resources in protected areas. Communal Property Associations (CPAs) were established to help represent their communities in such matters of natural resources ownership and control. Despite; the formation of the CPAs, the participation of these associations in the management of the nature reserve in Dwesa-Cwebe has been questioned and under scrutiny. Therefore, this study seeks to understand the dynamics around the participation of the Dwesa-Cwebe Community Property Association in the management of Dwesa-Cwebe Nature Reserve. The study sought to find out experiences of the members of Dwesa-Cwebe CPA regarding their participation in the management of Dwesa-Cwebe Nature Reserve. Some questions needed to be answered, such as: To what extent is the membership in Dwesa-Cwebe CPAs a true representation of the needs of the local communities in the management of Dwesa-Cwebe Nature Reserve? What are the challenges faced by the members of the Dwesa-Cwebe CPA in representing the local communities in the management of the Dwesa-Cwebe Nature Reserve? What recommendations can be provided to solve the challenges faced by the Dwesa-Cwebe CPA in the management of Dwesa-Cwebe Nature Reserve? The study utilised a qualitative research methodology to obtain the answers to the main research questions. The study utilised convenience sampling to select ten suitable participants who were prepared to participate in the study and who are members of the CPA from Dwesa-Cwebe area. The research used interviews and non-participant observation to gather data. The collected data was analysed using thematic analysis. The analysis of the data revealed that there is limited participation by the CPA members in the management of Dwesa-Cwebe Nature Reserve. The study’s findings also indicated the CPA members are not involved in the management of the utilisation of generated revenue. The findings of this study also revealed that there are benefits that are entrenched in the participation of CPA members in the activities of the Dwesa-Cwebe Nature Reserve. However, the participation mechanisms are not producing the desired outcomes. Based on these findings the study recommends that the management of the Dwesa-Cwebe Nature Reserve review their management approach so as to ensure effective participation by CPA members. Further, there is a need to produce reports that update the Dwesa-Cwebe community on how the management of the nature reserve is utilising the generated revenue and its development plans. , Thesis (MBA) -- Faculty of Business and Economic Sciences, 2021

The study utilised convenience sampling to select ten suitable participants who were prepared to participate in the study and who are members of the CPA from Dwesa-Cwebe area. The research used interviews and non-participant observation to gather data. The collected data was analysed using thematic analysis. The analysis of the data revealed that there is limited participation by the CPA members in the management of Dwesa-Cwebe Nature Reserve. The study’s findings also indicated the CPA members are not involved in the management of the utilisation of generated revenue. The findings of this study also revealed that there are benefits that are entrenched in the participation of CPA members in the activities of the Dwesa-Cwebe Nature Reserve. However, the participation mechanisms are not producing the desired outcomes. Based on these findings the study recommends that the management of the Dwesa-Cwebe Nature Reserve review their management approach so as to ensure effective participation by CPA members. Further, there is a need to produce reports that update the Dwesa-Cwebe community on how the management of the nature reserve is utilising the generated revenue and its development plans. , Thesis (MBA) -- Faculty of Business and Economic Sciences, 2021

- Description: In the South African context, co-operatives are mostly established to ease the impact of unemployment and poverty, particularly in rural communities. The Kruisfontein Cattle Farming Co-operative is no different, as it was formed by a group of farmers who were looking into converting their herd from that of a poor genetic quality, low-value breed to a superior quality breed. These farmers were all facing similar challenges prior to forming the co-operative and they hoped that through working together they would be able to overcome some of the challenges they faced and thus become a successful co-operative that can compete with established farmers. The Jeffery’s Bay Wind Farm carried a mandate from the Department of Energy, through the REIPPP, to ensure that a portion of its profits is redirected to assist communities that are within a 50km radius of the JBWF. The Kruisfontein Cattle Farming Co-operative became part of the programme and the JBWF’s project manager became the person responsible for the smooth running of the programme. However, research conducted in this field has revealed that in most cases project managers in the renewable energy sector encounter challenges when implementing community development initiatives and they may lack an in-depth understanding of what community or social development entails, as it might not necessarily be an area of expertise for them. Therefore, this study aimed to explore how the Kruisfontein Cattle Farming Co-operative has influenced the livelihoods of the beneficiaries. The theories that were adopted and deemed applicable to this study included the traditional modernisation theory, dependency theory and sustainable development. The study employed a qualitative approach and a case study research design. The study made use of primary data collected through semi-structured interviews and documents, and an interview schedule was employed to carry out the interviews. In terms of sampling, the researcher made use of convenience sampling, which is a form of non-probability sampling. All the members of the Kruisfontein Cattle Farming Co-operative, which was the entire population of the study, were interviewed, thus making the sample type a census. The study explored how the Kruisfontein Cattle Farming Co-operative has influenced the livelihoods of the beneficiaries and revealed that since the involvement of the JBWF, the co-operative has recorded several achievements such as fencing around the grazing land and cattle kraal as well as calves of a superior breed that will enable the beneficiaries to receive good prices when selling their cattle. However, the co-operative is faced with challenges associated with weak livelihood assets, as the asset pentagon illustrated that the beneficiaries have moderate access to physical, human and social capital, while their natural capital is low, and their financial capital is significantly low. An overreliance on nature-based activities as a livelihood strategy is also a challenge facing the co-operative. Lastly, notwithstanding the abovementioned challenges, it can be concluded that the Kruisfontein Cattle Farming Co-operative has had a positive influence on the livelihoods of the beneficiaries, as they indicated that they experienced reduced vulnerability through the fenced grazing land and anticipated an improvement in their financial capital status through the increased income they would receive from selling cattle of a superior breed. , Thesis (MADS) -- Faculty of Business and Economic Sciences, 2021

- Description: To address the persistent challenge of the high level of unemployment, poverty, and inequalities, in 2006, the South African government initiated the Community Works Programme that provides an employment safety net for people living in marginalized areas where access to employment opportunities is very limited. The study aims to investigate the contribution of the CWP on poverty alleviation in the Western Cape Province. A qualitative research approach and a qualitative survey questionnaire were used to conduct the study in the Western Cape Province of South Africa. The WC Province has a total target of 17 700 participants in the 27 sites established across seven districts with an average site size of 656 participants. A purposive stratified sampling technique was used to sample 90 participants. Semi-structured interviews, with open-ended questions, were conducted with all the 90 respondents. A thematic content data analysis process was used to analyse data. Findings such as positive contribution or benefits of the programme, economic benefits, personal development, and capacity building, and enhanced economic inclusion and opportunities will be discussed in this study. Recommendations will be made based on the findings of the study. The research findings have shown that the dominant perception expressed by the participants of the CWP was that the program has made a significant contribution to their livelihood. The primary research data also showed that most of the participants utilized the wages received from the programme to buy food, pay for municipal services, pay family educational needs, pay for personal educational needs, demonstrating that the CWP has made a significant contribution to the livelihood of the participants. The literature review reflected that with the high level of unemployment in South Africa, the conditions that necessitated the implementation of this kind of community public works programme remain intact and the intended beneficiaries remain vulnerable and marginalised. , Thesis (MA) -- Faculty of Business and Economic Sciences, 2021

- Description: Corporate Social Responsibility (CSR) is a strategy that is used by organisations to take responsibility for the social and environmental responsibility of where they are operating. The organisation has to make sure that the community in which they are operating benefits from their operations through Corporate Social Responsibility (CSR). The researcher conducted this study which focuses on the developmental side of Corporate Social Responsibility (CSR) as an instrument for supplementing the role of governments in developing communities, particularly in the Northern Cape, South Africa, where poverty and underdevelopment have become prevalent. The study explores CSR investments from a community perspective, community participation, supporting enterprise and social trust development within the respective communities. While Renewable Energy Independent Power Producers (REIPP) made every effort to implement CSR as part of their contribution to developing the communities they operate in, CSR is used as a tick box exercise for many. While some of these companies do it for more than just bragging rights, these CSR strategies normally follow a top-down approach. Some of these implementation programmes are purely based on desktop research and are so far removed from the current realities and needs of the communities that the money and effort spend does not have the multiplier effect that everyone desires. The study aimed to analyse Corporate Social Responsibility (CSR) from a community perspective, thus, the study explored the view of the community on Corporate Social Responsibility (CSR). The study discovered that many of the respondents have a general understanding of CSR and how it should impact the community. This impact, however, is not being seen with the research indicating that most of the youth are uneducated and unemployed. The majority have also pointed towards dissatisfaction and the lack of trust in how the government and REIPP are applying the renewable energy sector CSR principles within these communities. , Thesis (MBA) -- Faculty of Business and Economic Sciences, 2021

- Description: Fresh Produce Markets are an important sector in the agricultural value chain. The discussions on land expropriation, food security and job creation all demonstrate the potential that still exists within agriculture. The Fresh Produce Markets remain a solution to the distribution of food in South Africa and their existence remains relevant. Fresh Produce Markets in South Africa combined, generate about R15 billion, by distributing about 3 million tons of fresh produce. The main contributors to this success are the customers who are loyal to Fresh Produce Markets, regardless of distances these customers travel to get to Fresh Produce Markets. This study intends to understand how the East London Fresh Produce Market can put customer needs at the centre of their business, resulting in good Customer Experience. Positive customer experience promotes customer loyalty and assists organisations in encouraging brand advocacy. While customer experience has been explored in several contexts, regions and industries, customer experience at the East London Fresh Produce Market has not been measured. The literature review conducted investigated the field of customer experience. This literature review assisted in developing a conceptual model for customer experience for the East London Fresh Produce Market. This study follows a positivistic research approach, using quantitative methods of analysis. Exploratory factor analysis was conducted using data gathered from a questionnaire disseminated in hard copies and via e-mail. The sample of this study was selected at random using convenience and snowball sampling. A sample size of n = 210 was used in this study. Descriptive and inferential statistical analysis were conducted. The primary contribution of this study was the presentation and statistical assessment of an exploratory factor analysis of factors influencing customer experience at the East London Fresh Produce Market. This study found that the independent factors of Brand Experience, Service Experience and Post-purchase/Consumption Experience all have a positive effect on the overall customer experience and on each other. Furthermore, the statistical assessment suggested new factors of Product Quality and Range(s), Brand Experience(s), Empathy(s), Communication(s) and Facilities(s), which all are found to have a positive effect on customer experience and on each other. The study developed two models that presented the determinants of Customer Experience at the East London Fresh Produce Market. The models should assist managers, organisational leaders and marketers to improve their customer experience-related strategies and to gain competitive advantage. The results and insights obtained, resulted in understanding the factors that provide good customer experience at the East London Fresh Produce Market. , Thesis (MBA) -- Faculty of Business and Economic Sciences, 2021

- Description: Employee relations are important for the success of any organisation. Maintaining healthy cordial employee relations usually involves creating understanding and harmony between the employees and the employer. However, due to several dynamics within the work environment, employee relations become complex. The employee relations unit in the human resources management department is tasked with handling this complex situation by dealing with different grievances in organisations. In this regard, in organisations like the University of Fort Hare, the employee relations office represents both the employees and employer. The dualistic role assumed by the employee relations office is associated with several challenges, such as employees not trusting the employee relations office. The employee relations office is deemed to be safeguarding the interests of the management, which complicates employee relations at the university. Therefore, this study sought to explore perceptions on the dualistic role of the employee relations office and its influence on labour relations at the University of Fort Hare. The study utilised a qualitative research methodology to find out perceptions of participants on the dualistic role of the employee relations office and its influence on labour relations at the University of Fort Hare. The research used semi-structured interviews to collect data. The participants were purposively selected from the University of Fort Hare. The Human Relations Theory was used as the main theory, and it provided underpinning arguments regarding employee relations at the University of Fort Hare. The data gathered were thematically analysed. The main findings revealed that there are fragmented employee relations at the university, mainly due to lack of clarity about the standard working conditions that should be expected and that are acceptable by the university. Furthermore, the study also established that the employee relations office is largely seen as biased against employees and seems to favour employers most of the times, leading to disputes being taken to an external party. Based on these findings, the study recommends that to improve objectivity, the employee relations office can create an oversight team that independently provides insights on specific issues faced by employees and management. Improving objectivity should include making decisions based on facts or data, focusing on the vision and mission of the institution, increasing the ratio of positive against negative feedback, improving on transparency during decision-making and the creation of an anonymous human resources engagement system. , Thesis (MPA) -- Faculty of Management and Commerce, 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

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: 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
