- Description: Only 12% of the world's published plastic research includes references to Africa despite it being a significant contributor to the global plastic waste and mismanagement problem (~88.5% of Africa's plastic waste is mismanaged). Ocean plastics are transported from land by rivers to the sea. However, source contextualization is complex. Many African rivers predominantly run alongside human settlements that host informal waste dumpsites. In this study a simple cost effective, easily deployed, consistent and replicable survey methodology was employed. The study quantified macro plastic in three rivers discharging into Algoa Bay, South Africa. The results indicated that industrial Swartkops and metropolitan Baakens Rivers both illustrate moderate plastic pollution (>3000 plastic particles/day), with the relatively natural Sundays River to showing minimal evidence of river macroplastic (<100 plastic particles/day). The types of plastic were noted using the RIMMEL app (premier African implementation), enabling proportional comparison of different plastic litter types to be completed. , Thesis (MSc) -- Faculty of Science, Oceanography Department,2021

- Description: The Fourth Industrial Revolution (4IR) is set to disrupt existing economic and social structures through the use of cyber-physical systems that result from a fusion of the digital, biological, and physical spheres. The fifth and current long wave of innovation is going through such a digital revolution in the ongoing deployment period which is being driven by the generalpurpose technologies of Artificial Intelligence and the Internet of Things, among other cyberphysical systems. The impact of mobile money in the access of financial services has shown how disruptive incremental innovations in mobile and digital technologies can be. The transformational power of mobile money in financial access is due to its use as an accessible financial tool that utilizes mobile devices to send and/or receive money over great distances. With the 4IR looming, this thesis determines the factors that enable and constrain the adoption of a disruptive technology amongst Sub-Saharan African small, micro, and medium enterprises (SMMEs). Therefore, due to its impact on financial inclusion and the formalization of SMMEs, mobile money is used as an indicator for the adoption of 4IR disruptive digital technologies. The adoption of mobile money was evaluated using secondary data from a survey conducted by Research ICT Africa, which surveyed 4408 SMMEs in nine African countries. The Diffusion of Innovations (DOI) model and the Unified Theory of Acceptance and Use of Technology (UTAUT) model were used to identify the factors enabling and constraining the adoption of a disruptive technology, in this case mobile money. Factors included gender, vocational training, business skills training, tertiary education, services, performance expectancy, social media, location, and nine African countries (Kenya, Mozambique, Ghana, Nigeria, Rwanda, South Africa, Tanzania, Uganda, and Senegal). The factors were grouped into owner characteristics, firm attributes and country attributes. SMME owners with business skills (49%) showed the highest level of adoption in terms of owner characteristics, Kenyan SMMEs (21%) had the highest adoption between the countries surveyed, and social media (62%) showed the highest adoption in terms of firm attributes followed by the formal variable (47%). In general, only 29% of SMMEs surveyed adopted mobile money. The study found that women SMME owners were more likely to be affected by business formality when adopting a disruptive technology compared to male owned SMMEs. This is because informality often exacerbates other barriers/challenges women face such as lower access to finance, lower ability to exercise property, business, and labour rights, and lower visibility. The results also demonstrate that vocational training is more important than general tertiary education for the ii adoption of a disruptive technology such as mobile money. Furthermore, when using social media as a tool for business advice SMME owners were more likely to adopt the disruptive technology. The study suggests that to encourage African SMMEs to adequately adopt disruptive technologies of the 4IR, more women owned SMMEs need to enter the formal economy, and vocational training targeted at business skills must be promoted amongst all SMME owners. Eastern African SMMEs were found to be more likely to adopt mobile money compared to other African regions. The finding demonstrates the need for more African countries (particularly outside of the Eastern African region) to encourage innovation by addressing the four enablers of mobile connectivity (i.e. infrastructure, affordability, consumer readiness, and mobile services) which will in effect lead to economic growth and development. The study shows that to address country/regional differences, in addition to building the required infrastructure in terms of mobile internet connectivity, countries should increase the local relevancy of disruptive technologies between SMMEs. To achieve this the study suggests increasing mobile social media penetration rates. This is because when social media is used as a tool for business advice SMME owners are more likely to adopt a disruptive technology (as is the case with mobile money) due to the social influence of social media. , Thesis (MCom) -- Faculty of Commerce, Economics and Economic History, 2022

- Description: The land question is a highly contentious issue in post-apartheid South Africa. Land is considered as a valuable resource for sustaining the livelihoods of people yet it remains one of the most sought after and contested resource in Africa owing to her colonial past. Black South Africans were also immensely subjected to land dispossession during the colonization by the Dutch and later the British and forced land removals during the apartheid era. Although this historical context from a lens of “race" is important to note here given how it shaped the South African geography of land ownership, there is nonetheless another dimension; that of gender. The main assertion driving this study is that due to a number of contextual factors (such as women's cultural status, economic inequality and poverty), land ownership between women and men is highly unequal whereby the former owns less and is mostly marginalized from land rights. This study thus looks at the extent to which land redistribution improves the quality of life for women in Buffalo City. The land redistribution program is part of the land reform policy which is a post-apartheid design and implemented for the purpose of redressing historical land dispossession and create redistributive land equality and tenure. This study employed a qualitative approach to ‘explore’ the experiences of women who are the beneficiaries of the land redistribution program as well as the perspectives of key informants who are the officials of the Rural Development and Reform Department. The thesis used an exploratory research design which was suitable for the understanding and unpacking of women's experiences with the land redistribution program. A major finding of this study is that the women who benefited from the land redistribution program have successfully progressed from small scale subsistence farming to large scale commercial farming, significantly improving their livelihoods. Nonetheless, the lack of financial capital is a critical challenge as the land redistribution program gives access to farms that need maintenance and renewal with financial grants that are barely enough for starting up. This study therefore argues that access to land should be accompanied by access to financial resources and capacity building to empower beneficiaries to use the land and other resources effectively and efficiently. It is recommended herein that the department should give beneficiaries full ownership of the land allocated to them as opposed to the thirty- year leasehold. , Thesis (MA) -- 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

Some of these service delivery protests are violent in nature, resulting in the damage of public and private property. Therefore, it is imperative to scrutinize service delivery protests. The South African constitution states that municipalities have the responsibility to make sure that all citizens are provided with services to satisfy their basic needs. These services include water supply, sewage collection and disposal electricity, gas supply health services, roads, storm water drainage, street lighting, municipal parks and recreation. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2021

- Description: Traditional Afrikaner culture has often been associated with conservative beliefs, giving patriarchal figures such as the husband and father superior status. Although South Africa has undergone social progression, large numbers in Afrikaner communities still live according to old, patriarchal norms. My perceptions of Afrikaner masculinity, informed by my cultural background, enforce patriarchy's functioning in some Afrikaner homes, allowing the development of rigid expectations of a male's self-expression. These mind-sets of what masculinity is do not align with my values, beliefs, and the visual presentation of my identity. With the application of autoethnographic inquiry in this practice-based study, I was able to analyse and interpret the nuanced discrimination against the performance of my male identity in an Afrikaner cultural context. I implemented autoethnographic and practice-based methods to respond to and challenge outdated and conservative views regarding the prevalence of Afrikaner masculine ideals and their negative implications. The contribution of the research practice is FYN BOI, a fictive persona constructed and performed by me. He represents a liberated facet of my identity whose reaction is rejection against the Afrikaner cultural opinions of me, and in turn, is fuelled by the criticism to provoke further and challenge these views. The conceptual garments created are considered his wardrobe, which he uses in his self-expression online. With this unconventional approach to a fashion study, disseminating the research practice online instead of a physical exhibition allows for the study to be accessed to audiences beyond academia's domain. This undertaking intends to contribute to the existing discourse of masculinity and prejudice against individuals' self-expression of their identity. , Thesis (MA) -- Faculty of Humanities, School of Visual and Performing Arts, 2021

- Description: The purpose of this treatise is to identify the impact of in-store promotions on consumer buying behavior. Through utilizing real-world data, the study used a qualitative analysis by gathering input from people who are activity involved with in-store promotions. In-store promotions have been suspected to directly impact consumer buying behavior; however, there is no real proof of this. Furthermore, the theory suggests that in-store promotions should impact consumer buying behavior, but there could be a difference between what theory states against what is actually happening. Therefore, this study will be taking opinions and views from those working with in-store promotions and put it to the test against the theory. The aim is to determine whether in-store promotions is a viable source of marketing and if it can ultimately affect the consumers buying behavior. The treatise will also help the reader to understand the theory behind consumer behavior and what it entails. Interviews were conducted with store managers across South Africa to get more accurate data. By interviewing store managers from various regions, geographical skewness of data was prevented from occurring. This study further assists marketing professionals to have a more accurate understanding of what to expect when conducting in-store promotions. Marketing professionals will also be able to better predict the outcome such activities on the final purchasing decision of consumers. , Thesis (MAB) -- Faculty of Business and Economic Sciences, 2021

- Description: Healthcare services within a hospital setting are the basic aspects for the success of service delivery and staff performance in this regard. The paramount component of human resources makes a positive contribution to a healthcare system. Recently, it has been recognised that the performance of healthcare personnel ought to be a key factor for a sustainable performance system. Nevertheless, it is generally known that healthcare workers fail to accomplish the anticipated outcomes of health interventions. This concept leads to the research question: Why is the public sector known for poor service delivery and poor performance? This study aims to determine the factors that impact on the health worker’s performance in a tertiary hospital in South-Africa. A framework will be carefully constructed and cautiously implemented to improve and develop the performance of healthcare workers in this hospital. The vast scope and population involved in this study make a quantitative research approach most suitable, along with a non-probability purposive sampling method. A survey method using an electronic questionnaire that was circulated via a web survey, and a paper-based questionnaire that was distributed within the hospital were used to obtain a diverse perception of the healthcare workers. Data analysis included determining factors, group differences and correlations using the SPSS-27 program. The target population included all healthcare workers in the tertiary hospital – from junior employees to senior management level staff. Statistical data analysis collected for this study revealed four major factors (politics-related resources, resource, training and socioeconomic) that play a major role in the trends of performance culture at the selected tertiary hospital. These results lead to the understanding that the hospital is currently experiencing inadequate human resources management components such as recognition of employees who perform above expectations; execution of a performance appraisal system; lack in implementing the annual salary increase; unfavourable working conditions (lack of resources); troublesome management skills, and insufficient feedback on performance outcomes. These features are directly associated with the quality and degree of the performance of healthcare personnel. Based on the results, a management framework was proposed. The framework consists of activities that will improve the healthcare profession; strengthen expertise and knowledge; develop management skills; enhance knowledge through research and, ultimately, upgrade the performance of healthcare personnel. , Thesis (MPH) -- Faculty of Health Sciences, Public Health, 2021

- Description: The South Africa (SA) forest industry relies on plantations of exotic forestry trees (Pinus, Acacia and Eucalyptus) to fulfil its timber requirements. With 52.0% of the afforested land in South Africa planted to various eucalypts and their hybrid combinations. Of the total area planted to eucalypts in SA, 75 000 ha is re-established annually by means of silvicultural regimes and operations matched to site productivity, desired end-product and method of regeneration. Unlike other commercially grown tree species, eucalypt species have the ability to coppice after felling. Coppicing is a common form of regeneration in South African forestry as it allows the plantation owner the option of a second timber rotation without replanting. However, if any factors affecting coppicing are compromised, and the site is to be replanted, then it is important to kill the stumps before replanting as rapid initial growth of the coppice shoots will require earlier control than that associated with normal weeding operations. Over time, various methods of woody plant control have been proposed and tested, with most of these making use of herbicides as opposed to the repeated manual removal of coppice regrowth. Globally, most industries subscribe to standards associated with sustainable production (economic, environmental and social) against which they are measured. Within SA, 80% of the forests are certified though either the Forest Stewardship Council (FSC) or International Standards Organisation (ISO) which recommend the identification and avoidance of ‘highly hazardous’ chemicals; the promotion of ‘non-chemical’ methods for pest management as an element of an integrated pest and vegetation management strategy; and the appropriate use of chemicals that are used. To test the current recommendations for killing eucalypt stumps to include other species, the potential of reducing herbicides used, and the influence of time after application on the survival of eucalypt stumps, two trials were initiated at Entabeni plantation (Venda, Limpopo) and one at Wilgeboom plantation (Bushbuckridge, Mpumalanga) between 2018 and 2020. Extending eucalypt cut-stump control practices: Most of the trial work on killing of eucalypts in SA has been conducted on Eucalyptus grandis, Eucalyptus camaldulensis or Eucalyptus macarthurii, with all grown on shorter pulpwood rotations. To extend current recommendation to include Eucalyptus cloeziana (grown on a longer rotation for poles), a trial was established in 2018 at Entabeni plantation (Limpopo Province) to quantify the interaction between Application method (basal-frill; cut-surface; foliar) and Herbicide (no herbicide applied; Roundup; Garlon; Roundup + Garlon) for the killing of 12 year-old stumps following harvesting. Assessments were carried out at 1, 3 and 6 months following application and included Stump survival, Stump quarter with coppice and Coppice heath. Relative to the control plots (100% survival), all herbicides tested were equally effective, 70–90% of the stumps killed. This study confirms previous research regarding the killing of eucalypt stumps. Roundup, Garlon or a combination of two, when applied according to label recommendations to a stump as a basal-frill or cut-surface application (within 30 minutes of felling) resulted in 70-90% of the stumps killed. , Thesis (MSc) -- Faculty of Science, School of Natural Resource Management, 2021

- Description: Successful development projects are not only grounded in proper planning and implementation but also in evaluation. Numerous development projects are implemented successfully but lack evaluation. This study evaluates the Joint Action Project (JAP) waste intervention that took place in Gqeberha Township in February 2020. The intervention was designed and implemented by a group of student volunteers from Nelson Mandela University (NMU), Port Elizabeth (PE) College and Wismar University. This was a collaborative project between Development Studies, Human Settlements Development, Electrical Engineering, Communication and Design as well as Architecture students who worked together to construct a workspace for a male informal waste picker residing in Gqeberha township. The study adopted a qualitative research approach and data was collected through interviews and field observation. Although the findings of this study revealed that there were some challenges encountered by the beneficiary and the JAP team during the project implementation, the benefits of the intervention exceeded these challenges. These benefits include the improvement of the beneficiary’s livelihood and waste picking business, improvement of health and improvement of the environment surrounding the intervention site , Thesis (MADS) -- Faculty of Business and Economic Sciences, 2021

- Description: The common carp, Cyprinus carpio is a highly invasive fish species, first introduced into South Africa in the late nineteen century, and now widely spread throughout the country. In 1991 carp were illegally introduced to Groenvlei, within the Goukamma Nature Reserve in the Western Cape Province. Decreases in water quality and declines in biota have been attributed to the now large numbers of carp. Management measures have commenced to reduce the carp population, however these are not underpinned by science as little is known about the biology and movement patterns of resident carp. The age, growth and maturity of carp within the lake was determined using oxytetracycline hydrochloride marked asteriscus otoliths and macroscopic gonad development staging methods. The results showed that carp in Groenvlei had similar growth characteristics to the invasive populations in North America and Australia; fast growth during the first three to five years and reproductive maturity attained between the ages of two to three years, and are long lived (maximum age of 20 years old). Their growth however differed from the only other study on a South African population. Six acoustically tagged carp were manually tracked in order to report on their movement patterns and habitat use. Carp moved much greater distances in February compared to October and November, and occupied different areas of the lake. In November they were found to aggregate in backwaters which corresponds with their breeding activities. Literature on global carp control shows that whilst eradication of this fish can be achieved in small isolated waters using icthyocides and water drawdowns, in conservation priority areas such as Groenvlei where this is not possible, mechanical removal using multiple gears targeting vulnerable life stages can most efficient at controlling carp. This study identified where and when these methods could be focused to optimise control efforts. , Thesis (MSc) -- Faculty of Science, Ichthyology and Fisheries Science, 2022

- Description: In this study, the continuous flow synthesis of anastrozole intermediates were investigated using mesitylene as starting material. Anastrozole is an important drug used for the treatment of breast cancer. In the first step, mesitylene was brominated using N-bromosuccinimide to obtain 3,5-bis(bromomethyl)toluene. Selectivity became an issue due to the formation of two by-products; namely 1,3,5-tris(bromomethyl) benzene (the tribrominated by-product) and 1-(bromomethyl)-3,5-dimethylbenzene (the monobrominated by-product). Since the reaction parameters can be more precisely controlled in flow chemistry systems, we were able to optimize the formation the desired product 3,5-bis(bromomethyl)toluene. The reaction was initially optimized ina 15μLChemtrix glass micro reactor resulting in 100%conversion with 95%selectivity towards the desired product 3,5-bis(bromomethyl)toluenein 15 seconds, with a throughput of 0.006 g/h. The reaction was then scaled up in a 1.7 mLLTF reactor, equally yielding 100%conversion with 95%selectivityin 4minutes, with a throughput of2.01g/h. The bromination of mesitylene was also attempted in a homemade photochemical reactor consisting of a 3.02 polytetrafluoroethylene coil reactor and BLE-6T365 UV lamp. In this photochemical reactor, although 100%conversionwas again obtained only75%selectivity was achieved in 20minutes, with a throughput of 0.025g/h. This drop in selectivity was attributed to poorer mixing in the larger polytetrafluoroethylene coil reactor and possibly insufficient light penetration. The next step, involving the cyanation of 3,5-bis(bromomethyl)toluene to obtain 2,2'-(5-methyl-1,3-phenylene) diacetonitrilegave 100%conversion in 1 minute at 190 °C in a 1.7 mLLTFreactor, with a throughput of 5.2g/h. The subsequent methylation of 3,5-bis(cyanomethyl)toluene to obtain3,5-bis(1-cyano-1-methylethyl) toluene was investigated using a1mLpolytetrafluoroethylenecoil reactor, ultimatelyachieving99%conversionat40 °Cin 8minutes, with a throughput of 0.045g/h. Next, the bromination of3,5-bis(1-cyano-1-methylethyl)toluene using N-bromosuccinimideto yield 2,2'-(5-bromomethyl-1,3-phenylene)di(2-methyl propionitrile) gave 100%conversion at 120 °C in 4 minutes, with a throughput of 0.35g/h. Lastly, the multistep synthesis of 3,5-bis(cyanomethyl)toluene was done in two integrated 1.7 mLLTF reactors, using the predetermined optimum conditions to achieve 94%conversion towards 3,5-bis(cyanomethyl)toluene with a total r , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2021

- Description: The South African public education system has for a long time been criticised for a number of things, including failing to meet international quality standards, poor resource management and failure to cope with rapid changes in the global environment. One of the most scathing of all these attacks, however, has been that it continues to churn out thousands of unemployable youth year after year. One critical area of improving this state of affairs could lie in the avenue of entrepreneurial education. There is no doubt that there is a considerable need to have an educated citizenry in South Africa. Since the dawn of democracy, government has made concerted efforts to improve the provision of education especially to the previously disadvantaged sections of the population. However, it has been proven that there is an even more dire need to produce competent and skilled school graduates who will not only be prepared for the job market, but also those who will be creators of much needed employment. In the pursuit of entrepreneurial education, entrepreneurial development capability thus becomes an important factor that needs to be understood in line with other factors that can be used to enhance it. It is hoped that understanding these factors will assist education managers to consider their implementation in their respective organisations. This study sought to establish a framework that might enable South African schools to enhance the entrepreneurial development capability of these schools. Initially, the study sought to investigate the contribution that education and training, culture of entrepreneurship, funding and finance, human capital and workforce, engaging the private sector and regulatory framework and infrastructure make in achieving the entrepreneurial development capability of schools. After conducting an exploratory factor analysis, these variables were however reduced to three independent variables (fostering entrepreneurial culture, funding and extra-curricular opportunities and external stakeholder support) and one dependent variable (entrepreneurship development capability). A mail survey was conducted in 82 schools in the Harry Gwala district of KwaZulu Natal. The purpose of the study was to investigate where the identified independent variables positively contribute to the entrepreneurship development capability of these schools. The major findings of the study reveal a low level of prevalence of the independent variables (fostering entrepreneurial culture, funding and extra-curricular opportunities and external stakeholder support) and the dependent variable (entrepreneurship development capability) in the participating schools. The empirical results also showed that all three independent variables were significantly positively related to the entrepreneurship development capability of the participating schools. These independent variables are therefore important determinants of the entrepreneurship development capability of schools. , Thesis (MBA) -- Faculty of Business and Economic Sciences, 2021

- Description: The South African public education system has for a long time been criticised for a number of things, including failing to meet international quality standards, poor resource management and failure to cope with rapid changes in the global environment. One of the most scathing of all these attacks, however, has been that it continues to churn out thousands of unemployable youth year after year. One critical area of improving this state of affairs could lie in the avenue of entrepreneurial education. There is no doubt that there is a considerable need to have an educated citizenry in South Africa. Since the dawn of democracy, government has made concerted efforts to improve the provision of education especially to the previously disadvantaged sections of the population. However, it has been proven that there is an even more dire need to produce competent and skilled school graduates who will not only be prepared for the job market, but also those who will be creators of much needed employment.

- Description: The oceans cover nearly 70% of the earth’s surface and are responsible for fundamental functions such as climate, weather, temperature regulation, oxygen production and carbon dioxide absorption. Despite this, marine environmental protection has received relatively little attention in comparison to terrestrial efforts. One explanation for this phenomenon is that policymakers struggle to implement regulations that mitigate human influences on the marine environment while also ensuring that these settings are both protected and enjoyed by users. However, environmental issues caused by human influence are visible to millennials, which has inspired them to become future leaders and drivers of environmental movements. As a result, they have the potential to make a significant contribution to environmental practices and legislation. The research aim was to explore the pro-environmental behaviour of millennials towards the marine and coastal environment through a mixed method systematic review. The systematic review yielded a total of 24 relevant research articles published from 2010 through 2020 in accredited journals. These articles were subjected to thematic analysis revealing three major themes, namely, (1) altruism, (2) environmental leader and (3) barriers to pro-environmental behaviour. The main results showed that millennials possess altruistic behaviours, however, it should be mentioned that according to the research, millennials' attitudes, concerns, beliefs, and desire for environmental change may not always translate into actual behaviour. The systematic review further emphasised the lack of journal articles that focused explicitly on millennials and their pro-environmental behaviour towards the marine and coastal environment within the selected databases. The dearth of research in this area, therefore, suggests that policymakers should provide incentives for such research to be conducted. , Thesis (MA) -- Faculty of Business and Economic Sciences, 2021

- Description: This study is concerned with the promotion of local music creatives. The literature explores ways to help the independent music creatives successfully navigate in the music industry by adopting a protean career profile. The research question that was explored in the study was whether or not the independent popular female creatives in the city of Gqeberha’s music industry adopted protean career profiles for successful career navigation. These pop music creatives’ profiles were compared to those of classical creatives for further insight. Relevant literature was analysed to collect data about what international authors have discovered about creatives’ successful navigation of their careers. The information that was gleaned from the analysis indicated that numerous individuals have adopted the profile of the protean career to successfully navigate their environment. The rationale for adopting the protean career profile was that it is directly related to one’s employability. Although the working world (including the music industry) is rapidly changing, this notion of employability will enable an individual to remain updated about the latest trends in their work environment and thus successfully navigate that environment. This concept was applied to research among music creatives in the South African (SA) context. Although there was limited research on the protean career profile, the published research findings that were available indicated that employability and information were in alliance with the international research on the protean career (which constitutes one’s employability). Employing qualitative data collection procedures, the researcher interviewed 14 independent female music creatives with different backgrounds, roles and experiences. Interviews were semi-structured one-on-one as well as focus groups. This narrative strategy of inquiry helped determine whether or not these individuals had adopted the protean career for successful navigation of their working environment. After data collection the researcher engaged in a cyclical coding process for deep analysation of the data utilising atlas.ti. The data was reduced from codes to categories, and eventually towards linking categories. The findings from the study revealed that the participants’ environment (surroundings) did not sufficiently support them, the creatives do not have sufficient guidance in their music paths and not all of them had adopted the protean profile. , Thesis (MA) -- Faculty of Humanities, School of Visual and Performing Arts, 2021

Protecting the right to identity against catfishing

- Description: Catfishing is a form of impersonation occurring on social media that interferes with a person’s right to identity. It involves creating a fake profile online using another person’s images. The facets of the right to identity are image, name, and likeness, among others. Catfishing affects a person’s right to identity and human dignity. Hence, the thesis aims to determine whether the right to identity adequately protects individuals against catfishing. This thesis is a desktop analysis considering the South African legal framework related to the right to identity, including the common law, the Constitution of the Republic of South Africa, 1996, and legislation. The thesis is also a comparative analysis assessing the adequacy of addressing catfishing through the right to identity. The study evaluates the right to identity’s adequacy by juxtaposing the South African legal framework with California and Oklahoma’s common law and statutory interventions. The study reveals that the right to identity protects South African social networking website users against catfishing. Like the common law right of privacy in California and Oklahoma, a person infringes the right to identity when they use another person’s identity facets to portray them in a false light, and like the statutory right of publicity in California and Oklahoma, a person infringes identity when they appropriate facets of another person’s identity for commercial gain. The infringement of the right to identity entitles a person to legal remedies, including a claim for damages, among other things. The thesis also considers principles of conflict of laws to determine the operative law in an instance where a victim resides in South Africa and the perpetrator resides in the US, or vice versa. The study recommends that developing the common law to recognise that identity can be infringed by mere appropriation not linked to a commercial purpose would be beneficial for addressing catfishing adequately in South Africa. Legal development contributes to the constitutional imperative to align the common law with society’s shifting needs and address novel legal issues, such as catfishing. , Thesis (LLM) -- Faculty of Law, Law, 2022
