- Description: Commercial property development and investment provide many benefits to individuals and governments around the globe; these include the generation of income for investors, employment, tax revenues, and contributions to a country‘s GDP. Yet commercial property development and investment projects involve construction, economic and management risks. A lack of effective risk assessment and management tools may lead to developers and investors incurring losses. To curtail such losses, this study sought to create a credible management model that can be used to assess and manage risks in Ghana‘s commercial property development and investment industry. An extensive literature review was done, covering all 12 identified study constructs: real estate trends and cycle, construction project management, outside advice/mentorship, spatial development, strategic factors, business management skills, PMBOK, PESTEL analysis, general management skills, governance structures, financial feasibility, professional feasibility, and risk management. Each construct was defined and operationalised. A positivistic philosophical approach was used, and quantitative approach was used to solicit data from the main respondents through the distribution of questionnaires to the target population sample. CB-SEM and SPSS version 24 were used to analyse data, SEM to test the positive relationships hypothesised between the identified variables and SPSS to analyse the demographic data. The major findings are that there is a lack of financial and professional feasibility analysis among respondents along the following factors: the PMBOK, real estate trends and cycles, general management, business management, strategic factors, spatial development, and PESTEL analysis. It was found that these factors have positive and favourable influences on CPDI projects. The study recommends that developers and investors do financial and professional feasibility studies before they embark on projects. This could improve project viability in commercial property development and investment. The study has contributed to the body of knowledge in CPDI sector by developing a new risk assessment/risk management model. , Thesis (PhD) -- Faculty of Engineering Built Environment and Technology, School of the built Environment, 2023

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

- Description: The effects of pests and the need to produce adequate food have influenced small-scale farmers in disadvantaged communities to adopt and utilise natural plant pesticides to improve harvests in many Southern African Development Communities. However, the phytochemistry associated with these indigenous plants’ pesticide activity still needs to be explored. The lack of evidence of scientific knowledge of the plant species has caused a lot of health issues among the users of indigenous plant pesticides. Solanum incanum is among the plants utilised to control cabbage aphids in Mkoba village, Zimbabwe. Solanum species are known for their steroidal compounds which comprise glycoalkaloids and saponins. This study evaluated the knowledge, opinions, and attitudes of the vegetable peasant farming community in Gweru regarding their use of the indigenous plant (S. incanum) as a pesticide. The study also reported the phytochemical profiling, structural characterisation of the isolated compounds, and biological and pesticidal activity evaluation of phytochemicals isolated from S. incanum. A descriptive survey was carried out to assess the knowledge, attitude, and practices of a conveniently sampled group of vegetable farmers in Mkoba village who use S. incanum as a pesticide. Forty-nine respondents comprised of 19 males and 30 females of ages ranging from 15 to above 60 years took part in the study by answering an open and closed-ended questionnaire. The survey revealed that parents and neighbours were instrumental in disseminating pesticidal information in the community. Brassica napus were the most grown.vegetable and vulnerable to cabbage aphids. Mixed opinions amongst the respondents varied regarding the health and environmental impact of S. incanum as a pesticide. Seventy-five percent (75%) of the respondents supported the use of S. incanum as a pesticide whilst 25% claimed that the use of S. incanum was the source of the health problems experienced in the community. The survey demonstrated that (45)91% of the farmers displayed poor practices regarding the disposal of empty pesticide containers and the use of personal protective clothing. The most prevalent symptoms in the community were skin rash, nausea, headache, and poor vision and these symptoms were common in the age group 30 to 60 years. , Thesis (PhD) -- Faculty of Science, School of biomolecular and Chemical Sciences, 2023

- Description: Morphologies have evolved due to trade-offs between competing selective pressures. This is especially true for the skull. Not only does it contain the brain and the organs that are responsible for sensory function, but it is also contains components that play important roles in feeding, breathing, balance, defence, aggression and communication. The pinnipeds, a group of species that has evolved from terrestrial origins and became adapted to the marine environment, are under numerous selective pressures within the marine environment. These species have had to evolve in order to capture and process food underwater, and to dive. In addition, they are also characterised by substantial sexual size dimorphism in some species. Pinnipeds also make use of numerous marine and haul-out habitats with varying characteristics and complexity. Hybridisation has been recorded among pinnipeds, resulting in the production of hybrid offspring with characteristics that are different to their parent species. The aim of the study was to investigate the effect of these life history characteristics on skull and mandible morphology of pinniped species using three dimensional geometric morphometrics. To achieve this, 43 skull and 15 mandible 3D landmarks were collected using a Microscribe G2X digitizer with 0.2mm accuracy, on the skull and mandibles of 17 species of pinnipeds across three families, and one hybrid species. In total, 96 specimens across these species were examined. Data on the different life history characteristics of each species were collected from the literature. These data were plotted onto the PCA results in order to create and visually compare minimum convex polygons for each life history category. The results found that phylogeny, feeding strategy and sexual dimorphism were the most important factors in explaining differences in pinniped skull and mandible shape and size. may have resulted in these changes. Similarly, the inclusion of more species, covering a broader range of life histories may be beneficial. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2023

- Description: The increase in the number of channels driven by technology trajectory over the years have led to a change in customer behaviour. Customers move around different retailer platforms during a single purchase; even so customers still expect a superior and seamless customer experience while navigating these channels. The present study built on studies conducted in countries such as China, Spain, India, United Kingdom amongst others to determine if the learnings from these countries can be applied in the South African context. This study used an interpretivist phenomenological approach and interviewed a qualitative sample of participants to gain insights on their experiences while shopping in these retailers. This study will assist Information Technology managers with prioritisation of their technology roadmaps. This study will also contribute to computer science studies because programmers will have a context of a customer’s perspective when developing omnichannel solutions. Lastly, the study can be used by governments and policy makers in developing national strategic plans relating to shared economy because the study highlights the need to omnichannel retailing in remote areas. The findings from the research were summarised into five themes customer experience, convenience, product, support, and security. The optimal South African omnichannel retail experience is one that allows the customer to seamlessly move across channels by integrating the retailing mix elements of product, place, promotion, price. To achieve this experience, retailers must integrate the customer’s profile information and ensure that the customer’s payment details are secure and are able to seamlessly login in all the retailer platforms. Contrary to the researcher’s expectations, South African customers do not expect an omnichannel support. They expect to keep online support separate from in-store support. , Thesis (MA) -- Faculty of Business and Economic Sciences, 2023

- Description: Palaeoichnology, the study of fossil tracks and traces, has had a relatively late start on the Cape south coast of South Africa. Since its inception in 2007 the Cape south coast ichnology project has led to the identification of 326 Pleistocene vertebrate ichnosites in aeolianites (cemented dunes) and cemented foreshore deposits between the community of Arniston in the west and the Robberg Peninsula in the east, a distance of approximately 350 kilometres. As a result, significant palaeoevironmental, palaeocological and palaeoanthropological inferences have been made. This thesis brings together this corpus of work, and attempts to answer the question of how ichnology can inform the understanding of the Cape south coast Pleistocene environment, and how the trace fossil record can complement the body fossil record. Achieving this objective involves the development of a definitive regional account. This includes descriptions of the regional geological context, Quaternary sea-level changes, and the state of knowledge of the region’s Pleistocene palaeoenvironment, palaeoanthropology, and body fossil record, along with an understanding of the roles of substrate and taphonomy in regional ichnology. A discussion of geochronology includes the age results from specimens submitted for dating through optically stimulated luminescence – dated deposits range in age from Marine Isotope Stage 11 through Marine Isotope Srage 3. The body of the thesis is formed by systematic descriptions of the vertebrate ichnosites, accompanied by interpretation and comments. Three databases have been compiled: ichnosites, photographs, and photogrammetry images. In synthesizing this data, four underlying questions are addressed: what is the global relevance of the Cape south coast ichnosites, how can these studies complement the vertebrate body fossil record, how can they contribute to the understanding of Pleistocene palaeoenvironments and palaeocology, and how can they contribute to palaeoanthropology? The Cape south coast is of global ichnological importance. Unanticipated findings which augment the sparse reptilian body fossil record include tracks and traces of crocodiles, monitor lizards, very large tortoises (the first of their kind in the global record), and hatchling sea turtles. Two new ichnogenera have been erected to describe the sea turtle tracks, each containing a new ichnospecies: ustralochelichnus agulhasii and Marinerichnus latus. Avian ichnosites are the oldest in southern v Africa, and include the presence of tracks of larger-than-expected birds, which may represent large chronosubspecies or may suggest the possibility of extinctions which are not evident from the body fossil record. Unique examples of the non-hominin mammalian ichnosites include sand-swimming traces that resemble those of the ‘Namib mole’: as a result a new ichnogenus (Natatorichnus) has been erected, containing two ichnospecies, N. subarenosa and N. sulcatus. The first elephant trunk-drag impressions and the first pinniped ichnosites in the global record have been identified. The role of elephant tracks as precursors to coastal potholes was previously unsuspected. Equid tracksites indicate a widespread presence of the extinct giant Cape horse (Equus capensis). The identification of a giraffe tracksite represents a major range extension. In particular, tracks and traces of giraffe, crocodiles, breeding sea turtles, and sand-swimming golden moles have significant palaeoenvironmental implications. , Thesis (PhD) -- Faculty of Science, School of Environmental Sciences, 2023

- Description: This study analysed the use of social networking sites by undergraduate Public Relations Management students from Walter Sisulu University, Chiselhurst site. The reason for this study was to seek student’s opinions on what drove them to open SNs accounts, use social networking sites and examine these motivations in relationship to the building blocks of the uses and gratification theory, which are information search or education, selfactualization, socializing and entertainment. A qualitative online questionnaire was employed in this study. 218 questionnaires were sent through to the participants WhatsApp class groups, 168 questionnaires were answered and returned back to the researcher. The discovery of the study was that the participants are diverse in many different ways and made use of social networking sites for many various reasons. Furthermore, this study indicated that the participants were motivated to use social networking sites because they wanted to interact and stay connected with their family, peers and loved ones, and to meet people or create connections. The study argued that the participants’ reasons for use of social networking sites was not only for socialising but also for entertainment, self-actualization get academic and general information. This study concluded that SNs have a meaningful role in the life of a student’s life doing public relations management from Walter Sisulu University, Chiselhurst site. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2023

- Description: This study analysed the use of social networking sites by undergraduate Public Relations Management students from Walter Sisulu University, Chiselhurst site. The reason for this study was to seek student’s opinions on what drove them to open SNs accounts, use social networking sites and examine these motivations in relationship to the building blocks of the uses and gratification theory, which are information search or education, selfactualization, socializing and entertainment. A qualitative online questionnaire was employed in this study. 218 questionnaires were sent through to the participants WhatsApp class groups, 168 questionnaires were answered and returned back to the researcher. The discovery of the study was that the participants are diverse in many different ways and made use of social networking sites for many various reasons. Furthermore, this study indicated that the participants were motivated to use social networking sites because they wanted to interact and stay connected with their family, peers and loved ones, and to meet people or create connections. The study argued that the participants’ reasons for use of social networking sites was not only for socialising but also for entertainment, self-actualization get academic and general information. This study concluded that SNs have a meaningful role in the life of a student’s life doing public relations management from Walter Sisulu University, Chiselhurst site. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2023

- Description: The world is facing an unprecedented biodiversity crisis, endangering human wellbeing, human rights, and the future of life on Earth. This is because the state of the ocean is deteriorating due to increased human activities, which have resulted in the destruction of limited marine resources in terms of space, time, and quantity. Marine spatial planning (MSP) and the public trust doctrine are two concepts that have been proposed to address this ecological crisis. The relatively new notion of MSP has emerged as a comprehensive way to allocate ocean use in space and time to improve coordination and deliver a more sustainable use of the ocean space. While different States have utilised the public trust doctrine to manage trust resources for the exclusive benefit of their current and future citizens. The thesis examines the MSP process and the public trust doctrine in international law to determine international obligations that can be relied on to ensure State compliance at a domestic level. It was determined that MSP and the public trust doctrine are only implicit in certain international law instruments. The thesis further sets out to examine whether both approaches must be explicitly mentioned in binding international law instruments. The thesis is expected to determine whether the South African environmental law regime includes the public trust doctrine – expressly or impliedly. The public trust doctrine is not expressly provided for in the Constitution since section 24 contains an implicit duty. The implicit duty is a constitutional human rights imperative applicable to all environmental management statutes. The picture in South Africa’s environmental legislation differs because the public trust doctrine is expressly mentioned, albeit in different terminology in several environmental law statutes dealing with specific natural resources. However, the legislature failed to include an express public trust provision in the Marine Spatial Planning Act (MSPA). 1 The thesis then embarks on a journey of statutory interpretation. It examines the applicable canons of interpretation to determine whether the MSPA supports or contradicts the public trust doctrine. An implicit public trust duty was found in the MSPA. This exercise also led to the conclusion that the trusteeship clause in National Environmental Management: Integrated Coastal Management Act (NEM: ICMA) also applies in the same geographical area as the MSP Act. Moreover, there is no provision in NEM: ICMA requiring its provisions to be applied or read in accordance with MSP regulation. However, a thorough examination of the NEM: ICMA and MSPA provisions leads to the conclusion that there will be no conflict if both instruments are read together. The most significant finding of this thesis is that, due to the provisions of both statutes, the State, a trustee in NEM: ICMA, is also a trustee in the MSPA. Finally, the combination of MSP and the public trust doctrine in MSP regulation may have several positive impacts, which include useful intervention for the existential crisis that underpins South Africa’s maritime domain and the promotion of sustainable development of the ocean space for both current and future generations. MSP and the public trust doctrine should be used in tandem to ensure that the ocean space is developed sustainably for current and future generations. This thesis demonstrated that the ultimate impact of the State’s implementation of MSP on the relevant State actors is that they must constantly remind themselves of the full implications of their role as trustees of coastal public property to avoid violating their public trust duties. , Thesis (LLD) -- Faculty of Law, School of School of Public Law, 2023

- Description: The essence of this thesis was to study the effectiveness of integrating digital media technologies within the pedagogical approaches adopted and implemented in private and public high schools in a comparative manner. The study looked closely at private and public high schools of the Eastern Cape Province, to study the gaps of accessibility to technology by schools. The study identified the Eastern Cape Province as having a problem of poor performance in matric results at the end of each year as compared to other South African provinces. In order to select the relevant sample for the study, the researcher has utilized two secondary schools private and public in Makhanda Grahamstown and one public secondary school in Alice. The pragmatic paradigm was used to inform the study and used the mixed methods approach to data collection. The researcher distributed closed ended questionnaires to the learners in the three selected secondary schools and semi-structured interviews for the principals of the schools. The key findings reveal that the digital media tools are used for the teaching and learning purposes as well as communication to the schools’ stakeholders. The findings also revealed that various online platforms are utilized for teaching and sharing of information. For example, D6 and Ibambisa School Communicator app, WhatsApp groups for learners, Facebook, Instagram and School website for potential stakeholders. Hence, the results of this study should contribute to the field of ICTs and education in the country to solve the problems facing the teaching and learning systems of private and public schools of the Eastern Cape. Most schools (especially the public) do not have access to digital media tools in their classrooms. Thus, they still depend heavily on the textbooks, which may be outdated or not enough for all learners. In response to the issues faced by the Eastern Cape secondary schools and the findings, the researcher has suggested a model named the Digital Media and Pedagogy Integration DMPI Model of Communication. This model will contribute to the body of knowledge by providing advice to the Department of Basic Education on how teachers and learners can utilize digital media tools effectively. Also, the study has recommended that there is a need for provision of computer literacy training for teachers in secondary schools in this digital age. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2023

- Description: This thesis forms part of the Nelson Mandela University biomass and nanotechnology project, which aims at using agricultural waste for many applications, including biomedical applications, water treatment, and agricultural films. Pineapple leaf fiber (PALF) is one of the natural fibers with the highest cellulose content (about 80%), and they produce about 2.5–3.3% of the weight of green leaves. However, the other parts of the pineapple fruit, such as the leaves and crown, are still treated as waste due to a lack of understanding of the benefits and risks of these parts of the pineapple fruit. The transformation of PALF as a renewable and abundantly available natural residue into cellulose fibers (CFs) will reduce the waste accumulated in the atmosphere, and it will add value to the cultivation of pineapple. In the biomedical industry, CF is very promising in terms of drug delivery. Cellulose acetate is a remarkable biomaterial extensively used in biomedical applications due to its properties such as being non-toxic, non-irritant, biodegradable, heat resistant, and less hygroscopic. In this research, the isolation, functionalization, and characterization of cellulose from PALFs were conducted. The PALFs were dried and ground into small particles before being alkali treated with sodium hydroxide to remove the non-cellulosic components. Moreover, the remaining lignin in the residue was removed using sodium chlorite and acetic acid; this process is known as the bleaching process. The bleaching process resulted in white CFs, which was an indication of the successful removal of the non-cellulosic material. The obtained CFs were further functionalized using acetic acid, acetic anhydride, and sulfuric acid, and this reaction is known as the acetylation reaction. Subsequently, both treated, untreated, and functionalized CFs were characterised using the following instruments: FTIR, SEM, SPM, TGA, XRD, and XPS. In the FTIR data of raw PALFs, the following functional groups were more pronounced: C-O, C=C-O, and C=O, whereas peak C-O-C disappeared and peak CH2, C-O, were less pronounced. These FTIR results confirmed the successful removal of non-cellulosic components. The SEM and SPM images visually suggested the partial removal of hemicellulose and lignin from the raw PALFs after the chemical treatment, which are the cementing materials around the fiber bundles. The TGA studies revealed good thermal stability for the isolated CFs from PALFs. The XRD diffractograms of the PALFs showed a cellulose I crystal pattern where the peaks were located at angular positions (2θ) of around 18°, 26°, and 41°. Lastly, after the functionalization of CFs, the cellulose structure remained intact (not damaged); instead, the newly ix introduced functional groups (the acetyl group) were attached at the ends of the cellulose structure. These results are therefore confirmation of the successful removal of non-cellulose material from the PALFs after the chemical treatment. , Thesis (MSc) -- Faculty of Science, School of Natural Resource Science and Management, 2023

- Description: Personal Branding is deemed as an unavoidable aspect of entrepreneurship and social acceptance. Individuals should establish, develop, maintain and take advantage of a Personal Brand. The benefits of a Personal Brand should be embraced and used to market themselves and highlight their uniqueness. The aim is to investigate the relationship between Professional Life, Social Media Presence, Values, Competencies, Communication as the independent variables and Personal Branding as the dependent variable. It was concluded that there are important factors that positively influence Interpersonal Personal Brand as well as Intellectual Personal Brand, which are the two components that make up Personal Brand. There is limited research on the factors that influence Personal Branding in South Africa. Through literature review, factors were identified and used to form a conceptual model. This model was tested to measure their relationship with Personal Branding. An online questionnaire was distributed to MBA students, family and friends who made up the study’s respondents. The results obtained after conducting correlation and ChiSquare tests were used to determine the relationship between the identified factors with Personal Branding. This study explores how individuals can use Personal Branding as a marketing tool. These individuals include those who want to create or further expand their current Personal Brand and use it as a marketing tool. This treatise explored the factors needed to be considered for Personal Branding a marketing tool for individuals. Personal Branding can be used at the beginning of a career, during a transition of a career or even when wanting to explore a new career. Personal Brand was initially considered the only factor. However, this study concludes that Personal Branding is made of up of two components: Interpersonal Personal Branding as well as Intellectual Personal Branding. The findings concluded that independent factors, Professional Life, Values, Competencies and Communication all have a positive significant influence on Personal Branding as a whole, as well as the components it is made up of, Interpersonal Personal Branding and Intellectual Personal Branding. The independent factor Social Media Presence positively influences Interpersonal Personal Branding only. v This study makes theoretical contributions by broadening the definition of Personal Branding. The study defines the research methodologies for Personal Branding which could be used for future studies. The Associative Network Theory in relevance to Personal Branding is explored. The practical contribution of this research includes a hypothesised model which was tested. This study should be repeated to include a bigger sample size that is more equally distributed within South Africa. Additionally, for future studies, it would be recommended to incorporate the development of Personal Branding as an independent factor to measure its effect on Personal Branding. Another recommendation for further research is to conduct research on policies, which can be put forward to assist with the managing of Personal Branding for entrepreneurs. , Thesis (MSc) -- Faculty of Business and Economic Sciences, 2023

- Description: As the number of deaf people in the world increases, the amount of parents who are deaf, is also growing. The world is increasingly relying on technology from which deaf parents can, and do, benefit significantly. Deaf parents are able to rely on available technology such as assistive technologies to overcome functional limitations. However, assistive technologies are often abandoned within a short period of time of being acquired. The abandonment of assistive technologies is believed to be due to a lack of proper elicitation of requirements. Therefore, the problem identified in this research is a lack of understanding of end-user requirements of an assistive technology for profoundly deaf parents with infants. A literature review together with logical argumentation was conducted and applied to identify and recommend a method suitable for eliciting end-user requirements for assistive technologies. Thereafter, an integrative literature review and thematic analysis was done to extract needs and challenges of profoundly deaf parents with infants, and group them according to themes that emerged. Finally, making use of the recommended method and the extracted needs and challenges of profoundly deaf parents with infants, twenty-eight end-user requirements of an assistive technology for profoundly deaf parents with infants were elicited. The twenty-eight elicited end-user requirements consist of eighteen end-user requirements that express functions of an assistive technology for profoundly deaf parents with infants, and ten end-user requirements that express an overall goal/objective to be attained by profoundly deaf parents with infants when the assistive technology is designed and developed. To evaluate the elicited end-user requirements, only the eighteen end-user requirements that express functions of an assistive technology for profoundly deaf parents with infants were considered. The evaluation was done by assessing both existing and emerging assistive technologies to understand the comprehensiveness of the eighteen elicited end-user requirements that express functions of an assistive technology for profoundly deaf parents with infants. , Thesis (MIT) -- Faculty of Engineering, the Built Environment and Technology, School of Information and Communication Technology, 2023

- Description: Money laundering has become common in the world and the introduction of cryptocurrencies has created another avenue that makes it easier to move funds between jurisdictions without anyone knowing. A block chain technology is used to process peer-to-peer electronic payments utilising decentralised virtual currencies known as cryptocurrencies. Although they are not yet regulated, cryptocurrencies are prevalent in South Africa and pose a risk of being used for money laundering and other illicit activities. The regulation of cryptocurrencies in South Africa to prevent money laundering is what is being examined by this research project. The objectives were to understand the concept of money laundering, cryptocurrency and the inherent risks of cryptocurrency in money laundering. An analysis and examination of the difficult concept of cryptocurrency and the risks of money laundering was done. The study demonstrated that cryptocurrencies are decentralised convertible virtual currencies based on cryptographic algorithms. Cryptocurrencies are not monitored by a central body. The research reveals that the use of cryptocurrencies presents risks of money laundering and other illegal activities because of its decentralised, anonymous, peer-to-peer, and unregulated nature. The study focused on the prevention of money laundering using cryptocurrency. International regulatory frameworks of countries such as Canada, United States of America, European Union and Australia were discussed and compared to the South African regulatory developments. It was established that the legal frameworks developed by Canada, the United States of America, the European Union, and Australia aim to mitigate the risk of money laundering associated with the use of cryptocurrencies. Additionally, it was discovered that there is no legislative framework in South Africa to regulate cryptocurrencies, however SARB acknowledged that efforts are being made to develop one. ix It was determined that South Africa urgently needs regulatory interventions in the continued use of cryptocurrencies. The author presented recommendations based on this need, including incorporating cryptocurrencies into the current legal framework by designating them as financial products and adopting a proactive rather than a reactionary approach to the developments of cryptocurrencies. , Thesis (LLM) -- Faculty of Law, School of School of Criminal and Procedural Law, 2023

The study focused on the prevention of money laundering using cryptocurrency. International regulatory frameworks of countries such as Canada, United States of America, European Union and Australia were discussed and compared to the South African regulatory developments. It was established that the legal frameworks developed by Canada, the United States of America, the European Union, and Australia aim to mitigate the risk of money laundering associated with the use of cryptocurrencies. Additionally, it was discovered that there is no legislative framework in South Africa to regulate cryptocurrencies, however SARB acknowledged that efforts are being made to develop one. ix It was determined that South Africa urgently needs regulatory interventions in the continued use of cryptocurrencies. The author presented recommendations based on this need, including incorporating cryptocurrencies into the current legal framework by designating them as financial products and adopting a proactive rather than a reactionary approach to the developments of cryptocurrencies. , Thesis (LLM) -- Faculty of Law, School of School of Criminal and Procedural Law, 2023

- Description: The aim of the public sector is to deliver effective and efficient services whilst reducing these delivery costs (Price Waterhouse Coopers, 2007). In addressing this aim of public service delivery, the objective of the study was to investigate the impact of leadership on service delivery in a specific public sector. The researcher utilised a non-experimental correlation research design where the participants were entry level officials from region six within the National Department of Employment and Labour in the Eastern Cape, who reported to the first level of management (supervisors/team leaders). A probability sampling design with a cluster sampling method was used, wherein the population was grouped and a cluster was chosen. The sample consisted of officials who delivered services to the public at an entry administrative level either in a direct role or a supporting role. These officials reported to the first line of leadership in the hierarchy (supervisors/team leaders). Questionnaires were used as the primary source of data collection to solicit data from participants and obtain feedback on leadership behaviour on operational and service delivery issues in the workplace. The data was processed by statistical calculations of the mean, median, mode and standard deviation. The Cronbach Alpha as a test of internal validity, was used to test for reliability and validity. The findings of the study revealed that the department strived to improve leadership and service delivery in rendering public service which will naturally contribute to the 2030 vision of the National Development Plan and the fulfilment of the organisational mandate (South Africa National Planning Commission, 2012). , Thesis (MA) -- Faculty of Faculty of Business and Economic Sciences, 2023

- Description: Worldwide, the topic of inner-city decay and regeneration continues to attract a lot of attention from various parties and organisations. This is largely due to the fact that Central Business Districts (CBDs) remain the heartbeat of any city’s economic, social and political vibrancy. It therefore remains an ongoing process for the government and private stakeholders to keep on devising strategies aimed at revitalising the inner-city. The problem of urban decay is however experienced more in the developing third world and is characterised by high unemployment rates, high crime rates, depopulation, desolate-looking landscapes, abandonment of buildings, split families amongst others. Urban decay does not have one single cause, but rather a combination of many, including poor urban planning, redlining, poverty, suburbanization, and racial discrimination. These factors have resulted in urban sprawl as property owners preferred to migrate from the increasingly toxic social and economic environment that now became of the inner-city. The study seeks to investigate the current state of urban decay in South African CBDs with a case study of Gqeberha metro city, it also investigates current efforts and measures in place for regeneration and lastly, recommendations that have been put and continue to be put in place for inner-city regeneration. The state of inner-city infrastructure, property development finance options, town planning requirements and regulations and the investment case are other factors that have been investigated. Various other aspects of inner-city dynamics in the context of property development have been explored with findings from extensive literature review and structured interviews enabling the researcher to come up with recommendations for sustainable inner-city regeneration. , Thesis (MSBE) --Faculty of Engineering Built Environment and Information Technology, School of Built Environment and Civil Engineering, 2023

- Description: The usage of the internet both in our daily lives and in the operations of organisations has grown significantly in modern society. However, there are also risks and vulnerabilities associated with this, thus cyber threats. Cybersecurity has been put in place to safeguard the internet from these cyber threats, yet there is an ever-growing concern regarding the implementation of cybersecurity, both globally and in South Africa. With the increase in cyber threats, there is a growing need and demand for IT professionals with the requisite cybersecurity skills and knowledge to combat and mitigate these threats. However, an ever-increasing cybersecurity skills gap has been identified both globally and in South Africa. Yet the specific cybersecurity skills demand, needs and challenges of IT professionals in South Africa are currently unknown. This study therefore investigated the cybersecurity skills demand, needs, and challenges of IT professionals in South Africa by reporting on IT professionals’ perceptions in this regard. An online questionnaire was used to gather information for this and was distributed to IT professionals using various online platforms. According to the findings of the study, there are several challenges such as lack of time, lack of funding and a lack of resources that South Africa must overcome in order to address the cybersecurity skills gap. From the survey results it was also found that neither tertiary institutions, nor organisations, nor the South African government are investing enough in cybersecurity skills development. Without the right cybersecurity skills set or investment in the development of cybersecurity skills, cyber threats will continue to increase and will potentially become more harmful to South African organisations and to the South African society at large. Furthermore, this study addresses the extent to which cybersecurity-related skills are required and currently used by IT professionals in South Africa to address the cybersecurity skills gap. Tertiary institutions, organisations and the South African government may benefit from this investigation as it could assist in the development of cybersecurity course work as well as national cybersecurity laws, legislations and policies. , Thesis (MIT) -- Faculty of Engineering, the Built Environment and Technology, School of Information Technology, 2023

- Description: Creep-resistant 1CrMoV steels are used for high-pressure turbine rotors in fossil fuel power stations operating at steam temperatures up to 565 °C in the creep regime. The upper bainitic microstructure of 1CrMoV rotors changes when exposed to high temperature service over long periods. The aim of this study was to relate these microstructural changes for service exposed 1CrMoV rotor steels to the remaining creep life as determined using existing methods. Analytical electron microscopy was used to quantitatively study the microstructural evolution of service-exposed 1CrMoV steel rotors. 1CrMoV rotor steel samples were characterised in the initial state, and three long-term (272 h to 300 kh) service exposed states. Detailed microstructural investigations were conducted to analyse the cavities; bainitic laths and packets; dislocations; carbide phases and their size, population, composition. The creep life fractions were estimated using conventional life assessment methods based on creep cavitation and hardness. The creep life fraction consumed of the rotors, estimated based on the creep cavities and hardness data, ranged from ~0.5 to 1. Electron backscattered diffraction (EBSD) was used to analyse the bainitic packets, laths, misorientations, and dislocations, which showed that the bainitic lath surface area to volume (SV) correlated with service time. The precipitates were extracted from the Fe-matrix using extraction replication and were further investigated using transmission Kikuchi diffraction (TKD), scanning transmission electron microscopy (STEM), selected area electron diffraction (SAED), and energy dispersive spectroscopy (EDS). STEM-EDS and TKD identified M3C, MC, M2C, M7C3, and M23C6 (M = Fe, Cr, Mo, V, Mn) in the 1CrMoV steels. STEM-EDS measurements revealed that Fe/Cr ratios in M3C decreased from 4.5 (initial state) to 2.5 (>272 kh). The Fe/Cr and Fe/Mo ratios in overall carbides decreased from 5 and 10 (initial state) to 1 and 2 (>272 kh), respectively. The TKD analysis indicated that the relative phase proportion of M2C and M7C3 carbides, relative to the total extracted carbides, is positively correlated with service exposure. These microstructural features correlate with the creep life fraction consumed and could potentially be used as another indicator of the remnant creep life. , Thesis (PhD) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics. 2023

- Description: This study investigates the role of Forte FM, Mdantsane FM and Rhodes Music Community Radios in disseminating the different kinds of messages on the nexus between the impacts of climate change and food security in the Eastern Cape Province, South Africa. Therefore, the study aims to investigate how these community radio stations play their informative, educative and entertainment roles regarding climate change and food security awareness programmes to their listeners. The study employed the qualitative research approach and convenience, and non-probability samplings techniques were subsequently used to select samples for this study. In-depth interviews were conducted individually for Forte FM, Mdantsane FM and Rhodes Music community radio programme managers respectively, who serve as the key informants. One focus group discussion each was held with residents of Golf Course, Mdantsane and Grahamstown areas where these radio stations broadcast from, with eight participants in each focus group. The total number of participants for the focus group discussions was 24 participants. The collected data were coded into themes using NVivo 12 software to generate the theme nodes and case nodes as key findings, analysis and then interpreted. The findings of this study confirmed that these three community radio stations do contribute to climate change communication through their programmes that focus on climate change and food security related issues. Another vital finding from the study showed that listeners do benefit immensely from these climate change and food security related programmes of the under-study community radio stations. Hence, listeners physical, social, and cognitive well-being of their climatic environment have been greatly impacted. In the same vein, the findings of this study further revealed that the rural communities who are mostly affected by the impacts of climate change on food security have been well informed and enlightened on the suitable ways to enhance a sustainable food security and climate adaptation system through Forte FM, Mdantsane FM, and Rhodes Music community radio stations. Significantly, this study has been able to come up with two suggested models and the conceptual frameworks, which are the Local Action Adaptive Communication (LAAC) Model and the Indigenous Behavioral Change Conceptual (IBCC) Model. These models are focused on increasing listeners interests, adaptation, and behavioral change on climate change issues. The models are also aimed at ensuring better climate change and food security communication Author. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2023

- Description: The importance of technological innovation transfer to a country’s socio-economic development cannot be underestimated. This is because technological innovation provides the base for today’s knowledge-based economy. As a developing economy, Ghana faces several socio-economic development challenges as those of other developing economies. Despite these socio-economic challenges, it has been shown that thriving Small and Medium Size Enterprises (SMEs) in Ghana, could help improve the socio-economic development of the Ghanaian economy. Notwithstanding the valuable contributions of SMEs to socio-economic development in Ghana, there appears to be a more significant disconnect between research outcomes from research institutions to SMEs in the areas of technological innovation transfer. It appears there is no bridge between research institutions and SMEs. Against this backdrop, the study aimed at investigating how the transfer of technological innovation from research institutions to SMEs could enable SMEs to thrive and improve the socio-economic development of the Ghanaian economy. A mixed methods research approach was used for the study. The study applied a stratified sampling technique to select 432 CEOs of SMEs from a total population of 481CEOs which represents all CEOs of SMEs in the Association of Ghana Industries (AGI) database in Accra, Ghana as of December 2018. A purposive sampling technique was also used to select ten (10) directors of research institutions from a total number of nineteen (19) research institutions, (including the CSIRs and public tertiary educational institutions), based in Accra, Ghana. The study site, Accra, Ghana, was chosen because of its thriving SME populations and world-class research institutions. While a probit regression model was used to address only the objective three (3) of the research objectives, a descriptive statistical analysis was used via the usage of the SPSS software to generate the mean, standard deviation and percentages on the trend and distribution of the study variables among the study population. However, thematic analysis which enables the examination of the data to identify common themes was used on the qualitative data. The empirical results from the study indicated that technological innovation received from research institutions did not address SMEs' needs and did not result in products and services needed by the Ghanaian community. The study found low collaboration between research institutions and SMEs; and indicated that policy direction towards research institutions and SMEs' collaboration was the essential factor in boosting the efforts to drive collaborations. The study has made a valuable contribution to knowledge by showcasing a framework for successfully transferring technological innovation from research institutions to iii SMEs. The study also contributes to the Helix and triple helix models of innovation by indicating that the successful transfer of technological innovation goes beyond the production of basic research by research institutions and the adoption of basic research by SMEs. Thus, successful technological innovation transfer hinges mainly on effective collaboration between the parties involved. In this regard, the study also contributes to theory, as it is one of the first studies to directly address the problem concerning how the transfer of technological innovation from research institutions to SMEs could enable SMEs thrive and improve the socio-economic development of the Ghanaian economy. The study could enable policymakers/governments to understand the existing gap between research institutions and SMEs and how they can work together to harness technological innovation for the betterment of socio-economic development in Ghana. It also generates new empirical knowledge on research and SMEs. The new knowledge in technological innovations could shape theory and policy decision-making, resulting in enhanced sustainable socio-economic development in Ghana. , Thesis (PhD) -- Faculty of Business and Economic Sciences, 2023
