- 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: The rise of humankind has caused pollution, increasing damage to the environment. The actions of humans over hundreds of years have led to an increase in the release of heavy metal cations in concentrations that are toxic to plants, animals and humans. These toxic metals can find their way into humans’ diets through water sources or bioaccumulation in plants and animals such as fish. Heavy metals such as lead and mercury are known to cause serious health issues when consumed, affecting the functioning of the circulatory and nervous systems and causing developmental disorders. Other metal cations, such as iron and copper, can be found in the human body. However, detrimental health issues can occur when normal concentrations are disturbed (either too high or too low). Iron, for example, can be toxic if in excess in the human body, causing damage to the liver and heart and can cause neuroinflammation and Alzheimer’s disease. Many methods have been employed to detect and measure the concentrations of toxic metal cations. However, these methods are performed in a laboratory and need skilled operators using expensive equipment. This results in long and tedious sample collection, long feedback time and costly analysis. Chemosensors have been researched and proposed as a cost-effective, on-site, real-time alternative for use as metal detectors. Chemosensory can selectively detect specific metal cations and can be sensitive up to the nanomolar range. Various chemosensors have been synthesised and screened for their colourimetric and fluorometric abilities. Colourimetric chemosensors can be used to visually detect cationic and anionic analytes, whereas fluorometric chemosensors are used to detect anions using their emission properties which handheld devices can measure. , Thesis (PhD) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2023

- Description: The global livestock production systems are changing due to a variety of factors, which have an impact on the price of red meat. The supply of weaners (cattle) is affected by a number of factors including the type of production system, feed costs, diseases and weather conditions. The demand for weaners (cattle) is affected by factors including, amongst various others, consumers’ perception of quality, value for money, health benefits, economic profile, expandable income, urbanisation and socio-economic factors. These factors are complex and interrelated in terms of their potential impact on weaner prices and have a significant influence on production and investment decisions in the industry. This study used quantitative research to investigate the relationship between the factors influencing the price of weaners (cattle). For the purpose of data collection, a closed ended questionnaire was distributed to the respondents. This study was done using non-probability sampling. The sampling method used in this study is referred to as snowball sampling, which is a process using networks. The data was analysed to conclude which factors are impacting the price of weaners (cattle) the most. The results show that the supply factors of weaners are experiencing increasing pressure with changing weather conditions, input costs and animal diseases. The demand factors such as quality, currency and population are increasing the complexity, which implies the market is changing from a producer orientated market to a consumer orientated market. The study provides a framework to predict future prices of weaners, which is expected to influence both production and investment decisions which contribute toward the sustainability of the industry. The study recommends that the South African weaner (cattle) industry has experienced a significant increase in demand, both locally and globally. Meeting this growing demand has its own complexity that limits weaner farmers’ supply of weaners. The market is changing from a producer orientated to a consumer orientated perspective, which will force the supply chain to keep up with the changing consumer factors. , Thesis (MA) -- Faculty of business and economic sciences, 2023

- Description: To investigate the potential anti-diabetic/obesity properties of oral cannabis administration in an obese and streptozotocin (STZ)-induced diabetic rat model, as well as an obese rat model, and to determine the mechanism of action, with a focus on the peritoneal and intramuscular fat depots. Experimental Design: Obese and STZ-induced diabetic rats were allocated a high fat diet (HFD) and intraperitoneally injected with STZ to mimic an obese and diabetic state. The rats were then orally administered cannabis extract (CE) of 1.25, 2.5 and 5.0 mg/kg body weight (relative to tetrahydrocannabinol (THC) content) or metformin as a positive control. For the obese rat model, the rats were allocated either a high carbohydrate diet (HCD) or high fat diet (HFD) and orally administered with cannabis extract of 1.25 mg/kg body weight (relative to THC content). Weight, blood and insulin-resistant parameters of the rats were monitored. The mitochondrial to genomic DNA ratio (MT:18S DNA), average adipocyte area of the various adipose tissues, citrate synthase and carnitine palmitoyltransferase 1 (CPT1) enzyme activities of the peritoneal and intramuscular fat were measured. Gene expression levels of uncoupling protein 1 (UCP1), cell-death inducing DNA fragmentation factor alpha like effector-a (Cidea), perilipin, hormone-sensitive lipase (HSL) and mitochondrial transcription factor A (TFAM) were measured in peritoneal fat, intramuscular fat and brown adipose tissue (BAT). Main Findings: Obese and STZ-induced diabetic rat model: Due to the biphasic nature of cannabinoids, cannabis dosage plays an important role in the observed effects. CE1.25 was the only cannabis treatment effective in improving the insulinresistant parameters of the rats unlike the other higher cannabis concentrations (CE2.5 and CE5.0). In the peritoneal fat, CE1.25 increased MT:18S DNA, increased citrate synthase activity, and decreased the average adipocyte area when compared to the STZ group. CE1.25 also induced fat beigeing by upregulating gene expression levels of UCP1 and Cidea. XIX Furthermore, an increase in gene expression levels of perilipin, HSL, and TFAM showed increased fat mobilization and metabolic activity. In the intramuscular fat, CE1.25 also reduced the average adipocytes area. However, a different mechanism of action was observed where CE1.25 did not induce fat beigeing, but instead increased both citrate synthase and CPT1 enzyme activities and gene expression levels of HSL, thereby indicating increased fat oxidation and mitochondrial activity. , Thesis (PhD) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2023

- Description: This study examines the effect of Illicit Financial Flows (IFFs) and capital flight on Zimbabwe’s economic growth and development. The study data covered the period 1980-2020 applying the Autoregressive Distributed Lag (ARDL) regression model to assess the relationship between IFFs and capital flight and Zimbabwe’s economic growth and development. Most empirical studies on developing countries show that in both the short and long run, IFFs and capital flight not only reduce the revenue base of the economy but its multiplier effects result in a negative significant relationship between economic growth and development. This supports the continued call for policymakers and government to develop effective policies and continue to have intergovernmental and bilateral engagements to share knowledge and information to deter and control these activities. Unless these activities are controlled, most developing countries will have revenue shortfalls that will have to be funded from Other Donor Assistance (ODA), AID and loans. The study used two ARDL models to assess the impact of GDP and Manufacturing output to assess the impact. GDP and Manufacturing output have been chosen as the proxies of economic growth. Data showed that capital flight had a positive coefficient relationship with GDP in the long run. It was statistically significant and capital flight also had a negative and insignificant effect on manufacturing output during the period 1980-2020. Thus, Zimbabwe should effectively engage in policies and measures that identify and deter IFFs and capital flight activities because the multiplier effects of the activities have a negative impact on economic growth and development. The continued depletion of state resources discredits the objectives of the government to achieve the 2030 Millennium Development Goals. Government expenditure in nonproductive sectors must be avoided, instead, priority must be given to sectors that attract investors and stimulate economic growth and development. , Thesis (MA) -- Faculty of business and economic sciences, 2023

- Description: The growing population in South Africa’s rural municipalities, coupled with industrial expansion, continue to exert pressure on the available water resources. While service delivery demands are becoming a serious concern among residents in various municipalities, local governments need to improve the supply of essentials, such as water. This study examines water scantiness in the rural side of the Amathole District Municipality (ADM), with a prime focus on the water distribution and maintenance system. , Thesis (MA) -- Faculty of business and economic sciences, 2023

- Description: The Labour Relations Act (LRA) recognises settlement agreements and arbitration awards as mechanisms by which the rights of parties in troubled employment relationships can be asserted. Commission for Conciliation Mediation and Arbitration (CCMA) is a statutory body empowered to make and pronounce on such rights through settlement agreements and arbitration awards. The CCMA caters for those earning within the stipulated ministerial threshold falling outside the existing bargaining forums. However, not much empirical evidence is available to indicate the challenges experienced by parties when attempting to enforce those CCMA rulings to get defaulters to comply. South African law accepts settlement agreements as part of dispute resolution mechanism, but the experience of some who hold settlement agreements is such that they are exposed to prejudice when they are required to have the settlement agreement converted to arbitration awards which essentially requires alteration of the very settlement agreed upon. The broad objective of taking matters to the CCMA for resolution with the possibility of having them resolved at conciliation phase cannot be achieved if a settlement agreement is not worth the paper written on and must be made an arbitration award for enforceability. The two are not the same, nor should they be made to be and trying to give them a similar status for enforceability purposes brings about a myriad of unintended challenges. While it could be argued that there also exists section 158 (1) (c) of the LRA if the requirements of section 142A are challenging, it could also be said that such a provision is inaccessible to indigent individuals who may only be able to invoke that provision at the mercy of legal practitioners willing to take cases pro bono for those parties to even stand a chance at enforcing compliance with a settlement agreement that was entered into voluntarily. Such a system allows for employers to bail out on settlement agreements without consequence make a mockery of the CCMA. To a serious degree, this suggest lack of certainty on the part of CCMA and its ability to bring matters to finality which is an important element to realisation of justice. This study sought to examine the way settlement agreements and arbitration awards are enforced, with dedicated focus on the requirement that must be satisfied in order to have force and effect. With the above in mind, chapter one dealt with how settlement agreements and arbitration awards are given force and effect through the LRA as envisaged in section 142A. The chapter explored challenges brought by the enforcement process and what that may mean to the objectives intended by the legislation. Chapter two encapsulates the framework under which the CCMA operates and enforces its decisions, a framework envisaged to be less formal and non-legalistic for the expedient resolution of labour disputes. Chapter three touches on the challenges met with section 143 implementation and highlights some case law prior and after the LRA amendments. Lastly chapter four looked into the enforcement of international or foreign arbitration awards within the South African context given the affiliation with international organisations such as International Labour Organisation (ILO). While it may be good for South Africa to align herself with international practices, it is worth noting that South Africa is still developing in international arbitration as a mode of alternative dispute resolution, but its prevalence as a preferred dispute resolution mechanism is without a doubt increasing. , Thesis (LLM) -- Faculty of Law, School of Mercantile Law, 2023

- Description: The intensive nature of plantation forestry in South Africa requires efficiency and financial viability in production systems, amidst a complex growing environment subjected to changing macro-climatic patterns. The success of plantation forestry operations depends, amongst others, on our understanding of tree growth and wood formation patterns in response to variable growing conditions in both space and time. This study was conducted on the two most commonly used species in the southern and Eastern Cape forestry regions, i.e., Pinus radiata and P. elliottii. The region is regarded as highly suitable for plantation forestry in terms of climatic conditions, but soil characteristics pose several challenges due to nutritional disorders and poor drainage. The study focused on investigating the influence of both soil and climatic conditions on the growth and Wood Density properties of the two species, and to establish functional relationships where possible. The two species showed comparable growth rates at the reference age of 13 years on the range of sites sampled in the study area. An analysis of variance showed greater differences in Site Index between than within sample plots, pointing towards the possible influence of site on growth variation. Correlations between climatic variables and the growth of both species were generally weak and contradictory. Possible reasons for this phenomenon are discussed. It is proposed that the general favourable climatic profile of the region and hydromorphic nature of soils reduce the chances of significant correlations between variables influencing moisture availability and tree growth. The analysis of correlations between soil parameters and tree growth revealed some influence of soil organic C and Na on the growth of P. elliottii. This is discussed in terms of our understanding of the influence of soil parent material and soil ecology. The absence of any correlations between soil chemical parameters and the growth of P. radiata was conspicuous. This is in contradiction with earlier studies on the species in the region and can possibly be explained in terms of the site-specific fertilizing policy of the industry, as well as the less diverse range of sites sampled than in the past, which can mask or reduce nutrient limitations for tree growth. However, P. radiata did show a high level of sensitivity towards effective soil depth. Site-quality prediction models are proposed for the two species, but with variable application value due to the limited options of significant control variables that can be considered for inclusion in the models. , Thesis (MSc) -- Faculty of Science, School of Natural Resource Science and Management, 2023

- Description: The Criminal Law (Sexual Offences and Related Matters) Amendment Act 32 of 2007 (“SORMA”), was promulgated to consolidate the laws relating to sexual offences in South Africa. One of the most important aspects of SORMA was that it made provision for the prosecution of those who engaged in sexual acts with minor children. However, SORMA had a major drawback in that it not only criminalised consensual sexual acts with children by adults, but also criminalised consensual sexual acts between children themselves. Thus, children could be prosecuted for engaging in consensual sexual conduct with each other. Stemming from this peculiar position, the provisions of section 15 (statutory rape) and section 16 (statutory sexual assault), insofar as they related to the prosecution of adolescents for engaging in consensual sexual acts with each other, was constitutionally challenged by various human rights organisations. The Constitutional Court in Teddy Bear Clinic v Minister of Justice and Constitutional Development 2014 (2) SA (CC) found that the provisions of section 15 and 16 of SORMA were unconstitutional insofar as they criminalised consensual sexual acts between adolescents older than 12 but younger than 16. The original version of SORMA, for purposes of sections 15 and 16, defined a child as a person under the age of 16 years. Only children younger than 16 years received protection under SORMA. The provisions of sections 15 and 16 of SORMA were the subject of a constitutional challenge in Teddy Bear Clinic. However, the position of 16 and 17 year old children was not dealt with, as it did not form part of the issues that had to be decided by the court. Subsequent to the Teddy Bear Clinic judgment, SORMA was amended, and the amended version defined a child as a person younger than 18 years. Despite this, 16 and 17 year old children did not fall within the ambit of protection provided by SORMA. They were still exposed to prosecution for consensual sexual acts with their adolescent counterparts. Moreover, they were not protected against adult sexual predators who prey on young children. Effectively, SORMA provided some degree of protection, but such protection is not sufficient, and it is contrary to the best interests of the child principle. vi Thus, this research project seeks to highlight, assess and criticise the failure of SORMA to provide adequate legislative protection to 16 and 17 year old children. They still face the possibility of prosecution for consensual sexual acts with other adolescent children, and, they are not offered any protection from adult sexual predators. This position is unacceptable as it is contrary to the spirit and purport of the Constitution, specifically the best interests of the child principle, an important international law principle. Article 3 (1) of the Convention on the Rights of the Child provides that in all matters concerning children, the best interests of the child shall be a primary consideration. The African Charter on the Rights and Welfare of the Child provides that in all actions concerning the child, the best interests of the child shall be the primary consideration. Thus, the lack of protection of 16 and 17 year old children under SORMA is not only contrary to the Constitution, but also to a fundamental international law principle. , Thesis (LLM) -- Faculty of Law, School of Criminal & Procedural Law, 2023

- Description: The Living Archive as Pedagogy emerges from Northern Uganda’s experience of war 1986- 2008, between the Lord’s Resistance Army and the Uganda People’s Defense Force previously named the National Resistance Army. This period of war and post-war has been a difficult experience where finding solutions and mechanisms for transition or justice remain complex, restricted, delayed and consequently concealing the reality of lived marginalization from below. The Acholi of Northern Uganda went through predatory atrocities, painful humiliation and unwilled cohabitations with their oppressors during war and post-war. The study explores how the interlinking of archives and pedagogy as independent disciplines can extend possibilities for more transformative education horizons in bottom-up, post-conflict expressions. The study is immersed through a conceptual and theoretical framing in the boundaries of archiving and pedagogy, to understand how the war constructs Acholi’s lived experience in multiple complex ways. While the Acholi re-orient their lives post- war, we recognize their attention in affirming their human agency, ordering of new and different meanings, desiring a different liberation in post-conflict where responsibility in contexts of “up againstness” validates their dwelling and being in spaces that exclude them. The research acknowledges that pedagogy and archiving studies in post-conflict, needs restructuring to challenge the preserving of external and dominant epistemological purviews that order post-conflict reconstruction life. These traditions exclude the experiences of survivor-victims, are tone deaf to community-based groups articulations of post-conflict repair, and neither does lived experiences of the everyday gets organized as an outcome for knowledge. This is discussed at length, as the research responds to its central question of how living archive as pedagogy can offer a transformative education discourse. The conclusion of the study emphasizes self-representation through transformative knowledge positions of I am whom I am, Where I am, Where I Speak, and Where I think. These positions articulate a self-understanding that supports rehistrocizing of post-conflict society as a body resisting exclusion in dominant knowledge formation and institutional omissions. There is evidence of the research foregrounding the formation of person-hood from experiences of ‘up againstness” and knowledge/under-stand[ing] from below. The research facilitates a hermeneutical encounter with specific inscribed bodies of post-conflict experience, the Acholi and Wanjiku whose bodies archive a horizon of possibilities if a different and difficult reading vii of the world is done from locations of struggle to produce consciousness of re-becoming, or returning to the human. These pedagogical experience positions Acholi and Wanjiku as educators, and their lives a living archive. We the readers are invited to a learning process as willing ‘hearers’ of Acholi and Wanjiku testimony, to own responsibility as our practice to ensure they appear in the world to say their truth, as they defy conditions of their oppression. , Thesis (PhD) -- Faculty of Education, School of Education Research and Engagement, 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

- Description: This study explores the mechanisms contained in the Employment Equity Act of 1998 (EEA) that are in place to ensure that all employers comply with the EEA. The research introduces the topic and the background of the EEA and further discusses its important provisions. The EEA is an Act which was adopted to enable section 9 and 23 (1) of the Constitution. It is there to ensure equality in the workplace. The purpose of the EEA is to eliminate unfair discrimination in the workplace and promote equity for designated groups. This research discusses the application of the EEA and its interpretation by our courts. It does this by discussing leading cases of the EEA and other relevant fields of the labour law. Amongst other discussions in the research is the case of South African Police Service v Solidarity obo Bernard. In this case, a white female employee referred a matter of unfair discrimination to the court for her non-appointment, even though she was the only one who qualified for the job. The employer had preferred a black female candidate for the position. The court held that the discrimination was fair and relied on the employers Employment Equity Plan to determine whether the discrimination was just and equitable in terms of section 36 of the Constitution. Thereafter, this research considers the role of different bodies or structures that are in place to ensure compliance and implementation of affirmative action policies as outlined in the EEA. At the centre of this research is the role played by the inspectorate, the Commission for Employment Equity, and the Director General of the Department of Employment and Labour. These are the structures of the Department of Employment and Labour that are charged with enforcement of the labour laws and policies. Each structure has its own legislative duties. For example, in terms of the EEA, the inspector must conduct inspections for the employer’s workplace, make recommendations for compliance where it is necessary, and issue fines as a final sanction for non-compliance. On the other hand, the Commission for Employment Equity (CEE) investigating compliance, issuing annual reports, doing compliance reviews, issuing certificates of compliance and non-compliance and awards etc. In addition, the research also explores the enforcement penalties imposed by the EEA. It also incorporates a comparative study between the penalties imposed by South Africa with that of Namibia and Canada. This study will show how Canada’s EEA and South Africa are lenient compared to the Namibian one. In Namibia, non-compliance is not only sanctioned with fines but with other harsh sanctions that have detrimental effects on non-complying employers. Finally, the research makes a summary and findings of the study. Thereafter, it discusses the failures and shortfalls of the EEA.

- Description: This study explores the mechanisms contained in the Employment Equity Act of 1998 (EEA) that are in place to ensure that all employers comply with the EEA. The research introduces the topic and the background of the EEA and further discusses its important provisions. The EEA is an Act which was adopted to enable section 9 and 23 (1) of the Constitution. It is there to ensure equality in the workplace. The purpose of the EEA is to eliminate unfair discrimination in the workplace and promote equity for designated groups. This research discusses the application of the EEA and its interpretation by our courts. It does this by discussing leading cases of the EEA and other relevant fields of the labour law. Amongst other discussions in the research is the case of South African Police Service v Solidarity obo Bernard. In this case, a white female employee referred a matter of unfair discrimination to the court for her non-appointment, even though she was the only one who qualified for the job. The employer had preferred a black female candidate for the position. The court held that the discrimination was fair and relied on the employers Employment Equity Plan to determine whether the discrimination was just and equitable in terms of section 36 of the Constitution. Thereafter, this research considers the role of different bodies or structures that are in place to ensure compliance and implementation of affirmative action policies as outlined in the EEA. At the centre of this research is the role played by the inspectorate, the Commission for Employment Equity, and the Director General of the Department of Employment and Labour. These are the structures of the Department of Employment and Labour that are charged with enforcement of the labour laws and policies. Each structure has its own legislative duties. For example, in terms of the EEA, the inspector must conduct inspections for the employer’s workplace, make recommendations for compliance where it is necessary, and issue fines as a final sanction for non-compliance. On the other hand, the Commission for Employment Equity (CEE) investigating compliance, issuing annual reports, doing compliance reviews, issuing certificates of compliance and non-compliance and awards etc. In addition, the research also explores the enforcement penalties imposed by the EEA. It also incorporates a comparative study between the penalties imposed by South Africa with that of Namibia and Canada. This study will show how Canada’s EEA and South Africa are lenient compared to the Namibian one. In Namibia, non-compliance is not only sanctioned with fines but with other harsh sanctions that have detrimental effects on non-complying employers. Finally, the research makes a summary and findings of the study. Thereafter, it discusses the failures and shortfalls of the EEA. These critiques are made in comparison with other EEA such as Namibia, and further the researcher offers her personal critiques and recommendations to the current system.

- Description: South Africa has a violent and oppressive past. They are various historical incidents1 of extreme cruelty perpetrated by the previous apartheid regime. Much of the modern South African democratic state was forged by protests. During the 1970s and 80s, the legislator by passing unjust laws was used to assist the government to maintain the oppression of the people of South Africa. From the Soweto uprising in the 1970s to the current service delivery protests of the 21st century, gatherings have always had the potential for deadly violence. The motivation for this research started with the emotions evoked by the iconic picture of the body of Hector Pietersen2 being carried after being shot by the police. Strikingly the images of the killing by the police of Andries Tatane conjured further questions concerning the use of deadly force within crowd management situations. The research undertook an analysis of the use of force by the police during crowd management situations. A brief analysis of South African law relating to the use of force by the police prior to 1996 is provided. There are legislative prescripts for the use of force during the maintenance of public order. It must be noted that the legislation falls short on providing clear, concise authority for the use of deadly force. Normally, the use of force by the police and civilians for the purpose of arrest is regulated by the Criminal Procedure Act3 , whereas the Regulation of Gatherings Act4 providing the authority for the use of force by the police in crowd management situations to preserve public order. At first glance, section 49 of the CPA seems to validate arguments that it violates some constitutionally protected rights, among which are the right to dignity, life, to freedom and security of the person, against cruel, inhuman or degrading treatment or punishment and to a fair trial, which includes the right to be presumed innocent. Section 49 however, withstood Constitutional muster as set out in Re: S v Walters & another. As the right to life is a non derogable right.5 The limitation of this right may lead to constitutional scrutiny. The emphasis will thus be on ensuring that the balance with regards to proportionality in the use of deadly force is maintained. During the research it became apparent that the police, especially during crowd management situations, served political interests.6 This had the unintended consequence that the laws were applied to suit the political narrative and not the rule of law. The use of force in the policing arena is controversial. It is very clear that any misuse of force in crowd management situations will evoke the historical wounds associated with apartheid. However, within crowd management, the use of force and the authority to use deadly force is absolutely necessary. The Marikana massacre was used to highlight the mistakes that police have made during inappropriate use of force and its catastrophic consequences.7 It was observed that the legislative framework concerning the use of force, whether under section 49 of the CPA or section 9 of the RGA, is incoherent and too complex. The research argues for simplicity and accuracy within policy and applicable legislative alignment. The linkages from the applicable legislation to the institutional policies should never be outdated or incorrectly formulated. The violent rhetoric from politicians such as ex-president Jacob Zuma, 8 Minister Fikile Mbalula 9 and Bheki Cele10 fuels the argument that the police are susceptible to misdirected notions and may cause the police act unlawfully. The Constitution requires the police to “enforce the law”11 and as such there is an obligation on the police to do this within the constitutional parameters. The correct use of deadly force will only be achieved if the SAPS adequately resource, train and regularly refresh their members regarding the use of force when policing protests. , Thesis (LLM -- Faculty of Law, School of Criminal and Procedural Law, 2023

- Description: Salt marshes are one of the most productive ecosystems globally. These ‘blue carbon’ habitats are in many respects resilient to climate change effects, able to track sea level rise and act as carbon sinks. Since salt marshes are economically and ecologically essential habitats (for example providing foraging grounds for invertebrates, fish, birds and humans), understanding the processes that control their structure is crucial to best maintain ecosystem services provided by these habitats. For decades the importance of top-down forces, such as grazing, has not been recognised as being important in controlling salt marsh plant productivity. Rather, bottom-up forces, such as the availability of oxygen, was thought to be the main constraint to primary production. Therefore, a better understanding of salt marsh ecosystem dynamics and whether grazer control exists is needed. Although grazer top-down control has been demonstrated in salt marshes in locations such as the United States, this has not been investigated in South Africa. This is a crucial knowledge gap locally considering the importance of salt marsh ecosystems. The aim of this study was therefore to determine what role consumers play in structuring South Africa’s estuarine salt marsh vegetation, thereby also contextualising this process internationally. In order to achieve this, the abundance of grapsoid crabs was estimated and related to key salt marsh features, such as Spartina maritima stem height and stem density, which was quantified from observational surveys. Sampling took place at the beginning and end of the early-spring and late-summer growth period (September 2021 and April 2022) in the Knysna, Kromme and Swartkops estuaries. If a correlation was observed between crab density and salt marsh features, it was important to determine whether they consume the salt marsh vegetation or if the effect was due to their burrowing activities. Hence, the diet of grapsoid crabs was investigated using stable isotope and gut content analysis. To examine the importance of crab grazing in controlling the growth of salt marsh vegetation, crab abundance was manipulated in situ by means of exclusion cages. This experiment ran for five months in the Kromme Estuary, from November 2021 to March 2022 over the salt marsh growing season. An ex situ feeding experiment was also conducted on 30 crab specimens collected from the Kromme Estuary, during May 2022. These crabs were starved for 48 hours and thereafter fed different components of Spartina (growing and dead blades, and roots and rhizomes). The food consumed was quantified as the change in plant length and dry weight after 48 hours, which gave a maximum grazing rate for the different food sources. It was found that crabs are having a minimal impact on the salt marsh vegetation structure. Spartina maritima does form an important component of the diet of grapsoid crabs, however, this is not their only source of food, and possibly not their preferred source of food. They are however contributing to sediment properties through their burrowing activities. The iii ex situ feeding experiment showed that grapsoid crabs can consume all vegetative components of Spartina, with a significantly greater amount of roots and rhizomes consumed. There was no consistent effect in terms of the exclusion of grazers, indicating that other mitigating factors could be reducing the impacts of grapsoid exclusion in situ. Together, these findings contribute knowledge that can be used to inform conservation by quantifying what the salt marsh risks losing in the absence or overabundance of crabs, as has occurred elsewhere globally. These results influence how salt marshes are managed, and highlight how not recognising the importance of consumers, such as crabs, could misalign management objectives. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: Cybersecurity is an ever-growing area of concern both globally and in South Africa. The increasing number of cyberattacks daily has had a large effect on individuals, organisations, governments, and society at large. The growing need to combat cybercrime is accompanied by the increased need for skilled IT professionals to assist in protecting against cybercrime. Currently, there is a worldwide cybersecurity skills gap and a lack of IT professionals with the requisite cybersecurity skills. Many countries have developed their own taxonomies and common lexicons for IT and cybersecurity work, specifically for their context. This type of common lexicon is important to help assist in the development of skills. However, South Africa does not yet have its own cybersecurity skills framework to serve as a common lexicon for the South African context. Hence, the problem defined for this study is that, without a common lexicon of the cybersecurity knowledge, skills, abilities, and tasks (KSATs) required of IT professionals as they relate to specific IT job roles in South Africa, the cybersecurity skills gap cannot be sufficiently addressed. Such a lexicon could help drive the development of skills in South Africa and, in so doing assist in alleviating the cybersecurity skills gap. This study therefore presents a common lexicon by collecting job postings over a four-month period from 1 October 2020 to 31 January 2021. These job postings were analysed using a thematic content analysis. The results identified 20 common IT job roles, together with the specific KSATs relating to each job role identified. As a result, these job roles form part of a proposed cybersecurity skills framework for South Africa (CSFwSA) which could help and guide South Africa towards more targeted cybersecurity skills development. The proposed framework could also be useful in guiding tertiary educational facilities in the creation of cybersecurity curricula that represent the real-world expectations. This, in turn, could help South Africa to address the cybersecurity skills gap by better preparing IT professionals and ensuring that they are trained and skilled in cybersecurity. , Thesis (MIT) -- Faculty of Engineering, the Built Environment and Technology, School of Information Technology, 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

- 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

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: Tenofovir disoproxil fumarate (TDF) is a prescription drug used to treat and prevent human immunodeficiency virus (HIV) infections. It aids in the reduction of HIV in the body, allowing the immune system to function more effectively. This reduces the risk of HIV complications, such as infections, whilst improving the quality of life. TDF belongs to the nucleotide reverse transcriptase inhibitors category of drugs. These drugs limit the ability of the reverse transcriptase, an enzyme essential for each virus to replicate itself. A reduction in the cost of HIV treatment could improve supply security and make it more accessible to patients in need. Thus, this project aims to use flow technology to achieve a guaranteed supply chain and access. In this thesis, a method for the synthesis of TDF was developed using microreactors starting from the readily available adenine. The method was adapted from the traditional batch synthesis as currently there is no literature on the synthesis of TDF in flow chemistry. The batch methods used for the synthesis of the working standards were successfully translated to flow systems. For the best results to be obtained, optimisation of the reaction temperature, reagent molar equivalents and concentration was critical. From the optimisation studies, an improvement in conversion is evident throughout all stages. The flow synthesis of the first intermediate resulted in a conversion of 100 % in N,N-dimethylformamide in 6 min residence time. This study was conducted at 200 °C, which is higher than the boiling point of the solvent with the aid of a back pressure regulator. A key reagent in the synthesis of tenofovir, namely ((tosyloxy)methyl)phosphonic acid, had to be synthesised and it was successfully produced in 96 % yield. The second intermediate was synthesised through a successful coupling reaction between (R)-9-(2-hydroxypropyl)adenine and ((tosyloxy)methyl)- phosphonic acid, which afforded a 100 % conversion of tenofovir in 20 min total residence time. The multistep synthesis of tenofovir was a success as it afforded a 65 % overall conversion. The prodrug TDF was successfully synthesised at 120 °C with a 30 min residence time, yielding a conversion of 100 %. ii | P a g e This thesis consists of four chapters. Chapter one describes the background on HIV and a literature review on HIV drugs. This chapter also demonstrates flow chemistry and microreactors in detail and different routes for the synthesis of TDF in traditional batch methods. Chapter two provides a detailed methodology for batch synthesis and flow synthesis with analytical data. 1H-NMR, 13C-NMR and FTIR spectroscopy was used to evaluate all the compounds synthesised in this chapter. Chapter three thoroughly discusses the results that were obtained graphically, showing that the flow synthesis gives better yields than batch synthesis. In chapter 4, the conclusion of the whole investigation is stated along with the future work for the preparation of TDF. , Thesis (PhD) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2023
