- Description: Satoshi Nakamoto, the pseudo-identity accredit with the paper that sparked the implementation of Bitcoin, is famously quoted as remarking, electronically of course, that “If you don’t believe it or don’t get it, I don’t have time to try and convince you, sorry” (Tsapis, 2019, p. 1). What is noticeable, 12 years after the famed Satoshi paper that initiated Bitcoin (Nakamoto, 2008), is that blockchain at the very least has staying power and potentially wide application. A lesser known figure Marc Kenisberg, founder of Bitcoin Chaser which is one of the many companies formed around the Bitcoin ecosystem, summarised it well saying “…Blockchain is the tech - Bitcoin is merely the first mainstream manifestation of its potential” (Tsapis, 2019, p. 1). With blockchain still trying to reach its potential and still maturing on its way towards a mainstream technology the main question that arises for security professionals is how do I ensure we do it securely? This research seeks to address that question by proposing a decision-making model that can be used by a security professional to guide them through ensuring appropriate security for blockchain deployments. This research is certainly not the first attempt at discussing the security of the blockchain and will not be the last, as the technology around blockchain and distributed ledger technology is still rapidly evolving. What this research does try to achieve is not to delve into extremely specific areas of blockchain security, or get bogged down in technical details, but to provide a reference framework that aims to cover all the major areas to be considered. The approach followed was to review the literature regarding blockchain and to identify the main security areas to be addressed. It then proposes a decision-making model and tests the model against a fictitious but relevant real-world example. It concludes with learnings from this research. The reader can be the judge, but the model aims to be a practical valuable resource to be used by any security professional, to navigate the security aspects logically and understandably when being involved in a blockchain deployment. In contrast to the Satoshi quote, this research tries to convince the reader and assist him/her in understanding the security choices related to every blockchain deployment. , Thesis (MSc) -- Faculty of Science, Computer Science, 2021

- Description: Work means different things to different people and the different meanings they make of their work has the unique ability of contributing to a sense of identity. Support staff have to negotiate their personal identities and social identities to develop a work identity in the complex South African context that has its unique challenges. Exploring how support staff make sense of their experiences, when it comes to their identities, reveals what identity work strategies they use. An interpretative phenomenological method of inquiry was employed as an initial research method to explore the aspects that impact on the identity formation of support staff at Rhodes University. The study aims to investigate how support staff have constructed a work identity through their constructions of their experiences. Six participants were recruited through a purposive sampling method and data were collected using semi-structured interviews. The study revealed that support staff use the following identity work strategies to negotiate their identities: Financial, Personality, Career mobility, Roles, Status and Esteem, Subjective wellbeing. These themes were derived from the narratives of the participants, using the emphases in the data and suggest that support staff use identity work strategies both outside and within the workplace, when constructing their work identities. The study illustrates that as people ascribe different meanings to work, they will define and negotiate their identities in the workplace based upon those meanings. Identity work is indeed challenging for support staff because they need to use identity strategies that are enhancing to their self-esteem. Identity work is a challenging task because of the many tensions and demands of modern society, as adults negotiate their needs to provide for families and to find ways to construct their job status in positive ways. , Thesis (MA) -- Faculty of Humanities, Psychology, 2021

- Description: Music performance anxiety (MPA) is related to the experience of persisting, distressful, apprehensions about and/or actual impairment of performance skills in a public context, to a degree unwarranted given the individual’s musical aptitude, training and level of preparation (Salmon 1990). This research project set out to investigate learners’ subjective experiences of the effects of monaural beat (MB) vibrational frequencies on their experiences of MPA. The research project was a qualitative study based on a phenomenological research paradigm, which fundamentally aims to explore an experience in its own terms (Smith et al. 2009). The research participants consisted of four subject music pupils at St Andrew’s College and The Diocesan School for Girls and were interviewed through in-depth, semi-structured interviews over two practical examinations. The results suggested that various factors contribute to the experience of music performance anxiety, such as the performers’ perceptions of audience reactions, as well as the context of the performance. Self-esteem and the performer’s fragile sense of self-worth and self-confidence also play an important role in influencing their music performance anxiety. However, listening to monaural beats during a performance has the ability to lower levels of music performance anxiety by eliciting the following effects: an improved sense of confidence within the listeners; a sense of calm; the monaural beats working on a passive awareness level that allows the beat to operate at a sub-conscious level; the ability to focus better on the task at hand as well as benefit the listener in non-musical contexts such as studying; general concentration or ordinary tasks such as gardening or going for a run. The research suggests that listening to monaural beats during a musical performance can benefit the performer by lowering levels of MPA. As a result, the performer will experience an improved sense of confidence, calmness and the ability to focus better on the task at hand. Monaural beats have also shown to be a useful method of dealing with MPA instead of resorting to pharmaceutical drugs or other methods of coping such as playing games for distraction. , Thesis (MMus) -- Faculty of Humanities, Music and Musicology, 2021

- Description: Forensic linguistics is a relatively new field in South Africa. This field which forms part of the applied linguistic discipline seeks to look at the application of linguistic knowledge, methods and insights to the forensic context of the law. This is a forensic linguistic study that seeks to look at the use of African languages in the traditional courts. The researcher explored the traditional courts of Luyengweni, a rural area situated in KwaBhaca at Mount Frere in the Eastern Cape. The concept of African languages usage is explored within the boundaries of customary laws as outlined in Section 6 of the South African Constitution of 1996. To fully elicit the use of African languages in the traditional courts of Luyengweni this study employed an exploratory qualitative research design method. This research method allows for data to be collected from the participants using semi-structured interviews, observation and other qualitative methods of data instrumentation. Relevant community members of Luyengweni such as Chiefs and their councillors, ordinary members of the community and the court secretary were interviewed by the researcher and the data was translated, transcribed and analysed. The thesis made use of a thematic analysis. These themes showed that the use of African languages in traditional courts is still relevant, however, the imbalances of language use in both common and customary law need to be addressed. The study revealed that the traditional courts still serve as law institutions that people trust to bring about justice, therefore language use as one of the pivotal tools in the justice system needs to be considered for effective justice to be carried out. , Thesis (MA) -- Faculty of Humanities, School of Languages and Literatures, 2021

- Description: This thesis analyses the working and living conditions of seasonal workers. In the context of increased demand for processed and higher-value food products, the agro-processing industry has been identified as a main contributor in the South African labour market (Department of Agriculture, Forestry and Fisheries, 2012: 17). In an effort to achieve high production outputs while saving on operational costs, employers have been seen incorporating more non-standard labour. In the agro-processing industry, non-standard labour has been in the form of seasonal workers which has been a matter of concern to state structures tasked with ensuring company compliance with labour regulations, especially as it relates to the protection of workers within the industry. Many of these workers are offered little protection, sub-standard working conditions, irregular working hours, having little or no benefits, lacking skills and often facing a lack of trade union representation (Fourie, 2008:111). The introduction of section 198B of Labour Relations Act (LRA) has been designed to address the rights of non-standard workers and to provide protection against exploitative practices within various industries (Griessel, 2015:1). The thesis focuses its attention on the role of social reproduction and the labour process in perpetuating domination and inequalities within the workplace. Further, the thesis examines the challenges of non-standard labour and the difficulties of regulating it in practice. It also discusses the livelihood strategies adopted by seasonal workers when not employed, in this case, by Carara Agro Processing Services. The research adopted qualitative research techniques in the form of semi-structured interviews and used purposive and snowball sampling in accessing relevant data for analysis purposes. , Thesis (MA) -- Faculty of Humanities, Sociology, 2021
