- Description: The last 'Trial Update" reported on Comrade Moss’s case until mid-March. This report covers the period from that time up until 25th April.STADLER - "ANC EXPERT" Brigadier Stadler testified that the ANC had made certain calls to organisations within the country which, according to his "research", had been followed by organisations in the country. As examples he gave the ANC’s call for ungovernability, the formation of organs of people’s power and the destruction of town councils. During cross-examination Stadler conceded that he was not able to give examples of any direct link between the ANC and organisations inside the coutry but he said an inference could be drawn by looking at the ANC’s call and the behaviour of organisations inside the country.

- Description: Background: Insufficient iodine intake in pregnancy is associated with many adverse pregnancy outcomes. About 90% of African countries are at risk of iodine deficiency due to poor soils and dietary goitrogens. Pregnancy predisposes to insufficient iodine nutrition secondary to increased physiological demand and increased renal loss. Iodine deficiency is re-emerging in countries thought to be replete with pregnant women being the most affected. This review seeks to identify the degree of iodine nutrition in pregnancy on the entire African continent before and after the implementation of national iodization programmes. Methods: A systematic search of published literature will be conducted for observational studies that directly determined the prevalence of insufficient iodine intake among pregnant women in Africa. Electronic databases and grey literature will be searched for baseline data before the implementation of population-based iodine supplementation and for follow-up data up to December 2018. Screening of identified articles and data extraction will be conducted independently by two investigators. Risk of bias and methodological quality of the included studies will be assessed using a risk of bias tool. Appropriate meta-analytic techniques will be used to pool prevalence estimates from studies with similar features, overall and by major characteristics including the region of the study, time period (before and after implementation of iodization programmes), sample size and age. Heterogeneity of the estimates across studies will be quantified and publication bias investigated. This protocol is reported according to Preferred Reporting Items for Systematic reviews and Meta-Analysis protocols (PRISMA-P) 2015 guidelines. Discussion This review will help ascertain the impact of national iodization programmes on the iodine nutrition status in pregnancy in Africa and advise policy on the necessity for monitoring and mitigating iodine deficiency in pregnancy in Africa. This review is part of a thesis that will be submitted to the Faculty of Health Sciences, University of Cape Town, for the award of a PhD in Medicine whose protocol has been granted ethics approval (UCT HREC 135/2018). In addition, the results will be published in a peer-reviewed journal.

- Description: This study endeavoured to investigate the perspectives of principals and practitioners working in selected early childhood development (ECD) centres in the Buffalo Municipal District in the Eastern Cape, on the use of play-based techniques in educational and pedagogical practices of 3 to 4 years age group. Although most practitioners are aware of the significance of play-based learning, many report experiencing challenges when attempting to incorporate play-based strategies into their teaching of, and lessons aimed at, young children ages 3 to 4 years. For the purpose of ECD, it is recommended that the teaching of, and learning by, young children take the form of play (NCF, DBE, 2015). In this particular research undertaking, a qualitative design approach was adopted. A descriptive case study approach with semi-structured interviews as the key method of data generation was used to study play-based approaches between practitioners and children ages birth to four years at three ECD centres located within the Buffalo City Municipality District. Face-to-face interviews were conducted with the three principals of the ECD centres and six practitioners, during the data-collection phase. Recording of the interviews was done then they were transcribed and thematic coding employed before the data were analysed for themes. The study participants’ responses revealed that the insufficient professional training of practitioners, on play-based approaches, presented a challenge. Play as a way of teaching and developing young children is further hampered by a variety of issues such as poor infrastructure, unqualified practitioners, funding of the ECD centres and lack of relevant resources prevalent in the ECD sector. As the findings indicate, government intervention will facilitate the training of practitioners for in-depth knowledge and understanding of play methodology in ECD, while the sector will benefit from additional funding and infrastructure provision as this has impact on indoor and outdoor play-based activities, as well as the appointment of qualified human resources instead of job seekers. , Thesis (MEd) -- Faculty of Education, 2023

- Description: Property development is a sector which provides economic benefits to many countries worldwide. Such economic benefits are employment provision and GDP contribution to the economy. Interestingly, financial feasibility is one of the tools that can be used to ensure property development projects’ success. It has been therefore recognised that some of the property development entrepreneurs lack financial feasibility know-how which could position their property development businesses into a competitive edge and sustainability in this continuous fluctuating property market. Hence, the aim of this study was to examine the key factors and variable that drive financial feasibility in property development and generate a financial feasibility model which can be used by property development entrepreneurs to analyse the financial feasibility of property development projects. Based on the aim of this study, an extended review of the literature relating to property business, property development, demand planning and risk management within the built environment discipline was conducted in identifying factors affecting the perceived success of financial feasibility for property development projects internationally. The research reviewed literature in the property development industry by identifying the variables for profitability, outside advice, trend analysis and real estate strategies. The research methodology approach that was used for this study, a qualitative explanatory multi-case study where embedded unit of analysis and valuable insight was provided for the success of financial feasibility in property development internationally. Semistructured interviews were conducted with various industry experts as indicated below: • Project Manager at Property Company; • Project Manager at developer; • Development Manager; • Owner of Property Group; • Part time lecturer at NMU Built Environment; • Development consulting company CEO; vi • Trustgro Developments (Pty) Ltd: Managing Director; • Tswaranang Consulting – Managing Director; • Capelo Development Company (Property Development) Director; and • NMBM - Senior Director: Land Planning and Management. The interview questions and primary and secondary propositions were defined together with the validity and reliability of the research. The purpose of the qualitative research was to unravel key factors that determine the perceived success of international financial feasibility of property development projects. Replication logic was used to generalise the results and the findings of this research effort suggested that the following variables emerging from qualitative themes, positively influences the perceived success of the financial feasibility in property development projects: profitability, risk management, outside advice, trend analysis, property cycles and demand planning. The implication arising from this study is that the perceived success of international financial feasibility in property development projects has the following positive influencing factors: profitability, risk management, outside (specialist) advice, trends analysis, property cycles and demand planning which must be considered by property developers and investors to ensure the success of their property development interventions. The curriculum of property development and real estate management practice should equally take into account the afore-mentioned factors. , Thesis (MA) -- Faculty of Engineering, the Built Environment, and Technology, 2022

- Description: The purpose of this study was to evaluate the successes and failures of multiculturalism in South Africa and Canada through the lens of critical multiculturalism as its theoretical frame. As Canada is widely-acknowledged as having one of the best multiculturalism policy and implementation programmes in the world, this study aimed to draw lessons from the Canadian model of multiculturalism in order to make recommendations to improve multicultural practices in South Africa. It is worth noting that multiculturalism in Canada is not perfect as government still struggles to implement inclusive and reconciliatory programmes for the previously colonised Indigenous communities. This study used a qualitative thematic analysis to enable a comparison of multiculturalism in these two countries. The findings of this study suggest that having a comprehensive multiculturalism policy is fundamental to ensure that aspirations of a socially cohesive multiculturalism are not merely philosophical, but are formulated into government policies, with guidelines for implementation through the guidance of critical multiculturalism theory. The findings of this study also suggest that the persistent racialised socio-economic inequalities in South Africa continue to undermine multiculturalism and nation-building efforts. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2022

- Description: Preeclampsia is the new onset of hypertension and is one of the leading causes of maternal mortality in South Africa and the world. Preeclampsia is usually diagnosed after 20 weeks’ gestation. Due to South Africa’s poor level of antenatal care, the prediction of pregnant women at risk of developing preeclampsia can be an essential component of improving the level of antenatal. This study used an antenatal care dataset from a South African obstetrician. A review of the literature and existing systems was conducted to identify the eight risk factors. These risk factors are systolic blood pressure, diastolic blood pressure, maternal age, body mass index, diabetes status, hypertension history, nulliparity, and maternal disease. This study used antenatal care datasets from a South African obstetrician. Two models were developed that could accurately predict the development of preeclampsia, one before 16 weeks’ gestation and the other within three check-ups. The model was evaluated using five evaluation metrics: classification accuracy, area under the curve, precision, recall and F-Score. The results of this study show a promising future for the use of machine learning models in health care. To the researcher’s knowledge, this model is the first machine learning model for predicting preeclampsia using a South African dataset. Future work will revolve around validating the model on data collected from field studies in hospitals and clinics around South Africa , Thesis (MSc) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2022

- Description: In democracies and purportedly free market economies, questions of “who gets what, when, and how” ought to be resolved mainly through free competition, where those with the competitive advantage on merit are guaranteed to succeed. If it is political parties, they only have to compete well and fairly to win elections. If it is businesses, they ought to have the best value and price and they win customers. However, there are institutions which regulate this competition and political economic behaviour. Interest groups such as business chambers, industry and professional associations, as well as various structures of representation engage in the political economic space to sway the distribution outcomes from these “institutions” in the favour of their members. To do so, at times they use methods that affirm the principles and spirit of free competition and at other times, they do not. This thesis reviews the political economy of transformation within the construction sector in Nelson Mandela Bay to further advance knowledge within the subfield of political economy in South Africa. By looking at a specific economic sector, the study adds an important element to the sub-discipline, a nuance to the debates about the role of the state in the economy or macroeconomic policy and the much studied mining-energy complex. The study focuses on the role of small business forums created mostly by newcomers within the construction sector in the city and the methods they used to increase the share of their members in construction sector revenues. Their methods were unconventional and earned them the unfavourable term of ‘the construction mafia’. Through a grounded theoretical research process, this study details the story of the rise and fall of forums and dissects it in line with ongoing debates within political economy and related disciplines, particularly about the nexus between politics and business as well as the role of interest groups in pluralist political systems. Among other things, the study finds that the forums did not see the construction industry as a free market and did not take principles of competition in the sector as a given. As such, they sought to make and remake institutions of the sector in ways that could increase their share of revenues. In similar fashion to the roles of iinjoli nosokhaya in traditional isiXhosa ceremonies, they accorded to themselves the right to distribute benefits to their members contrary to legal and general market prescripts. , Thesis (PhD) -- Faculty of Humanities, School of Government and Social sciences, 2022

- Description: Globally social media has shown unprecedented levels of adoption and Social Media Analytics (SMA) is a rapidly growing topic. For governments, SMA holds the promise of providing tools and frameworks to collect, monitor, analyse and visualise social media data, usually driven by specific requirements from a target application. However, social media data is noisy and unstructured, and organisations struggle to extract knowledge from this data, and convert it into actual intelligence. This study argues that SMA can support intelligent decision-making for Citizen Relationship Management (CzRM). CzRM is a growing effort of governments around the world to strive to respond rapidly to their citizens by fostering a closer relationship thereby creating more effective and efficient service delivery. However, there is a little evidence in literature on empirical studies of any existing decision-making framework for CzRM and SMA adoption. In particular, there is a gap with regards incorporating SMA into decision-making for CzRM of governments, particularly in developing countries like South Africa. The aim of this study was to develop a framework that provides guidelines, including methods and tools, incorporating SMA into decision-making for CzRM in the Gauteng Provincial Government (GPG) and the Free State Provincial Government (FSPG) of South Africa. A Systematic Literature Review (SLR) and conceptual analysis method was conducted to design the Social Media Analytics Framework for Decision-making in the context of CzRM (the SMAF).

- Description: Globally social media has shown unprecedented levels of adoption and Social Media Analytics (SMA) is a rapidly growing topic. For governments, SMA holds the promise of providing tools and frameworks to collect, monitor, analyse and visualise social media data, usually driven by specific requirements from a target application. However, social media data is noisy and unstructured, and organisations struggle to extract knowledge from this data, and convert it into actual intelligence. This study argues that SMA can support intelligent decision-making for Citizen Relationship Management (CzRM). CzRM is a growing effort of governments around the world to strive to respond rapidly to their citizens by fostering a closer relationship thereby creating more effective and efficient service delivery. However, there is a little evidence in literature on empirical studies of any existing decision-making framework for CzRM and SMA adoption. In particular, there is a gap with regards incorporating SMA into decision-making for CzRM of governments, particularly in developing countries like South Africa. The aim of this study was to develop a framework that provides guidelines, including methods and tools, incorporating SMA into decision-making for CzRM in the Gauteng Provincial Government (GPG) and the Free State Provincial Government (FSPG) of South Africa. A Systematic Literature Review (SLR) and conceptual analysis method was conducted to design the Social Media Analytics Framework for Decision-making in the context of CzRM (the SMAF). The findings from the literature review revealed several benefits and challenges with SMA, in particular the shortage of skills, guidelines, methods and tools for SMA. These challenges were used to draft guidelines that were included in the framework, which consists of five components that can be used to derive intelligent information from SMA. The pragmatic philosophy and a case study design was used to generate an in-depth, multifaceted understanding of the underlying problems in the case of the GPG and the FSPG. The German North-West Metropolitan region was used as a third case study to provide a more global perspective and a case of a developed country in terms of Gross Domestic Product.

- Description: Since the dawn of South Africa’s constitutional democracy, the right to strike has been protected. It is perceived to be fundamental to orderly collective bargaining and the courts have stressed the need to ensure that it is not unjustifiably limited or undermined. In the collective bargaining process, employers and employees have mechanisms at their disposal and a power-play ensues. One such mechanism, for striking employees, is to withhold their labour in an effort to compel employers to succumb to their demands. Newspaper articles and the jurisprudence that has emerged from the courts illustrate that strike-related violence has become a destructive feature of industrial action.[1] Not only are strikes destructive to the economy but they are often associated with violence. The courts have been inundated with claims seeking to interdict violent and protracted strikes. While many commentators are of the view that strike violence is a result of underlying socio-economic issues, which should be addressed by the government, employers and the general public often bear the brunt of the destruction and mayhem left in the wake of violent strikes. In the wake of one of the worst tragedies, the Marikana massacre, which saw 32 striking miners shot and killed when police opened fire at Lonmin's operations in the Northwest province, the South African government, organised labour, and employers were compelled to take swift action to address the deficiencies that existed when it came to the constitutionally entrenched right to strike. The Labour Relations Amendment Act 8 of 2018 seeks to address this. Whilst some of the provisions introduced by the amendments have been the subject matter of litigation resulting in progressive judgments, other provisions are yet to be judicially tested. , Thesis (LLM) -- Faculty of Law, Department of Mercantile law, 2022

- Description: The crux of this study is an analysis of the relations between corporate power and public policy in South Africa, in the period 1996 to 2014. The study’s focus is on corporate power’s influence on South Africa’s public policy and the various means through which power is exerted by the former to shape and control the latter, through the influence of the public policy process and outcome. The study achieves this by arguing that the GEAR and BEE policies failed to achieve their stated objectives, and instead serve as conduits for the exertion of inordinate public policy influence by corporate power. The study analyses how the placing of ANC leaders on major corporate boards has influenced South Africa’s public policy. The study will also examine the ways in which private corporate donations influence public officeholders in the governing ANC. The study also seeks to explore why the ANC with its seemingly progressive stance and history is susceptible to following neoliberal policies pushed for by political forces largely but not exclusively outside the party in the industries described to be targets of redistribution, mining, energy, and finance. The study asserts that private corporate donations made to the governing ANC have a corrupting effect on public policy and corrode democratic decision making and ultimately the public good. This study presents the argument that the ANC-aligned black political elite was co-opted into the structure of economic dominance with the GEAR and BEE policies and hence the prevalence of neoliberal economic policy in post-apartheid South Africa. The study also addresses the intricate relationship between the corporate and political elite, business, and money in South Africa’s elitist public policy landscape , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2022

- Description: This research sought to analyse factors that affect media freedom at the South African Broadcasting Corporation using a descriptive research design and qualitative research methodology. Studies and media reports show that the South African Broadcasting Corporation is facing a myriad of challenges including woes related to media freedom hampering its mandate to inform, educate and entertain the public of South Africa. There is a dearth of studies conducted to understand the media freedom challenges at the South African Broadcasting Corporation. A qualitative approach was used in data collection, and in-depth interviews were utilised as instruments to collect data from participants. Non-probability sampling in particular purposive sampling method was used to select 4 directors, 4 editors and 4 journalists at the South African Broadcasting Corporation. Data was analysed using thematic analysis. The findings show that challenges facing the South African Broadcasting Corporation include poor legal environment as the broadcaster lacks support from government to implement effective policies to protect employees and create a media freedom environment to allow workers to carry out their work independently. The study found that the political environment in the South African Broadcasting Corporation at affects media freedom. Some political 0rganisations, influential individuals and entities are meddling in the operation of the broadcaster by trying to influence the narrative of the content broadcasted. The finding revealed that economic environment at the broadcaster is affects media freedom. The broadcaster is struggling financially resulting in poor income for employees, retrenchments, and inability to run approved programmes. In the context of constitution and policies, there is need for the South African Broadcasting Corporation to develop strategies that will specifically address both internal and external political, economic, and legal challenges it is facing if it is to be a high performing, financially sustainable, digitised national public broadcaster that provides compelling, informative, educational, and entertaining content via all platforms. , Thesis (MA) -- Faculty of Humanities , School of language Media and Communications, 2022

- Description: Cancer is responsible for the millions of deaths worldwide every year, being ranked as the second leading cause of mortality in the world. Triple negative breast cancer (TNBC) is the most severe type of breast cancer, as it is the most aggressive and difficult to treat. Current treatment methods involve surgery, hormonal-, radiation- and chemotherapy. These are costly and often have severe adverse effects. There has been increasing research in the development of alternative treatment methods to reduce the side effects of cancer therapeutics, as well as the cost. The rapidly growing field of nanotechnology has allowed for the incorporation of several diagnostic, targeting, and therapeutic agents into nanomaterials for cancer treatment. The application of gold nanoparticles (AuNPs) in the diagnosis and treatment of various types of cancers has been widely investigated. AuNPs vary in size, shape, and structure, allowing for the development of diverse formulations for various treatments. The use of green materials, particularly plant material, to synthesise nanomaterials has allowed for the safe, cost-friendly and eco-friendly production of AuNPs that can be used to treat TNBC. The aim of this study was to evaluate the efficiency of green AuNPs synthesised with Hibiscus sabdariffa to treat TNBC in a pilot murine model. Spherical AuNPs were synthesised using an aqueous extract of the calyces of this plant. The AuNPs were characterised using UV-Vis spectrometry, dynamic light scattering, high resolution – transmission electron microscopy, and in vitro stability testing. A cell viability assay showed that these AuNPs exhibited cytotoxicity towards E0771 cells in a dose-dependent manner, where cells treated with the highest concentration of AuNPs (250 µg/mL) exhibited the lowest cell viability (7%). During the in vivo pilot study, C57BL/6 mice were inoculated with TNBC using the E0771 cells. It was found that TNBC had rapidly spread, resulting in metastasis in the liver, as well as omentum and mesentery. This resulted in a number of mice dying; therefore, shortening treatment time of the AuNPs. It is suggested that AuNP treatment may have exacerbated mouse death by promoting ROS production in metastasised tissue, suggesting that AuNP treatment may not be suitable for stage 4 TNBC. Tumor analysis of caspase-3 content showed that the AuNPs exhibited potential pro-apoptotic activity in the tumours, prompting further research into the tumour uptake and apoptotic mechanism of these AuNPs. , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2022

- Description: A significant number of children in the South African context are exposed to community violence and become traumatised. In South Africa, many learners bring trauma histories into the classroom. To attend to this problem, it is important to understand how Exposure to Community Violence (ECV) affects learners, how this exposure is manifested in the classroom, and how teachers and schools can best support and mitigate adverse outcomes for trauma-impacted learners. The study aimed to understand teachers’ views and experiences on the effects of community violence on learners and the nature of the support that they offer to learners with trauma related to community violence. An exploratory design was used within which qualitative data was collected using semi-structured interviews. Data was gathered from Mkhankomo Full Service School, which is located in Lusikisiki. A maximum number of 10 teachers participated in the study and interviews were audio-recorded. Results of this study provide insight into the effects of community violence on the learners who were victims either directly or as witnesses. Based on thematic analysis, the results clearly showed that the effects of community violence were found to be mainly emotional, behavioural and psychological. All these effects were seen to affect the learners’ performance at school in the long run. In addition, the findings point to the teachers showing a willingness to support learners exposed to community violence, however, they felt ill-equipped to do so given that they had never worked with learners exposed to trauma. Also, in their attempts to support learners, teachers implemented support systems such as offering individual lessons to learners and additionally assuming supportive roles such as that of mentor and mother. Moreover, the findings indicated that teachers were not provided with any v training to help them work with learners exposed to trauma and their expectations for the Department of Basic Education to assist were not met. Consequently, the study provides an understanding of the effects of community violence on learners from the perspectives of teachers in the school. It also assists with information regarding teachers’ preparedness and ability to respond to learners’ chronic exposure to community violence. Furthermore, this study gives an understanding of teachers’ approach to supporting learners experiencing traumatic stress in the classroom. , Thesis (MA) -- Faculty of Health Sciences, 2022

- Description: Graduates expect to find employment after completing their tertiary qualifications, but they often face various challenges in finding employment. These challenges may be due to a variety of factors such as the type of qualification, structural changes in the economy, lack of experience, or the lack of relevant social networks. This has the potential to affect a graduate’s psychological well-being. The current study explored the psychological impact of unemployment in 100 unemployed graduates between 21 and 35 years of age in Pietermaritzburg. The study was quantitative and used two questionnaires, the GHQ-12 and a self-designed questionnaire, to collect data. Purposive sampling was used to obtain research participants. The Excel spreadsheet and a statistical software package called JASP (2020, version 0.12) was used to analyse data. The findings revealed that unemployment had a negative impact on the participants’ psychological well-being. Participants experienced feelings of high anxiety and depression, and felt stigmatised. Participants also felt shame and experienced lower self-esteem. Unemployment had a financial impact on participants, including financial dependency on family and friends. Some participants blamed themselves, the government system, and the education system for their unemployment. Participants reported to have a positive attitude towards employment, including remaining optimistic about their chances of finding employment. Participants used adaptive coping mechanisms, such as keeping a positive attitude, and maladaptive coping mechanisms, such as hiding their feelings. Further research needs to focus on psychological services that could assist unemployed graduates to find employment through building and maintaining their self-esteem and confidence which are key factors when initially seeking and obtaining work. Unemployment and its impact on psychological well-being has been shown to be to be a complex subject that requires intervention from different parties such as employers and health-care workers, as well as the education system.

- Description: All organisations, for-profit or non-profit, have strategic objectives as their raison d’être.

- Description: Aim This study aims to provide an understanding and a description of the short-term postfire regeneration and ecology of the fynbos-thicket vegetation on a coastal dune system in the southeastern Cape Floristic Region. Another aim is to assess the recovery of the vegetation community by assessing the growth forms and the disturbance response across a range of species from thicket and fynbos communities and to provide a belowground bud bank classification for each of these species in the coastal dune systems. Location The study site was the Mandela University Reserve and the Noordhoek dune fields, situated in Gqeberha, Eastern Cape, which is part of the south-eastern Cape Floristic Region. The study site hosts thicket-fynbos mosaic vegetation type that occurs in a Mediterranean-Climate Ecosystem (MCE). Methods Firstly, field observations and photographs of plant species were taken weekly to assess and identify the species that were emerging and persisting in the dune system in the first 12 months postfire. Phenological events of the species that emerged (e.g., flowering, fruiting, leaf growth, leaf yellowing, and leaf abscission) were also observed and reported on. Secondly, an excavation of 21 species (e.g., Jamesbrittenia microphylla, Euclea racemosa, Olea exasperata, Searsia laevigata) was conducted to classify the species into their belowground bud bank types. Results There was a rapid emergence of resprouters (facultative resprouters and obligate resprouters) in the first 12 months postfire. This was followed by their growth; primarily occurring after the rainfall events. The dominant resprouting species (facultative resprouters and obligate resprouters) entered the system two weeks after the fire. There was a significant difference in the time to the first emergence of the different regeneration groups postfire (P < 0.001): on average, obligate sprouters (OS) appeared 1 month after fire – two months earlier than facultative sprouters (FS) and four months earlier than non-sprouters (NS). There was no statistical evidence to suggest that the FS and non-sprouters NS emerged at different times postfire; however, most NS species were observed in the system 5 months after fire. 4 Exceptions were the NS species Pelargonium grossularoides and Mesembryanthemum aitonis, both annuals that emerged 1 month after fire. A wide range of OS species that appeared earlier in the system (e.g., Euclea racemosa, Olea exasperata, Searsia laevigata, and Lauridia tetragona) exhibit underground lateral growth with belowground bud banks (BBBs) from which they recover after disturbance. In total, six BBB types were recorded in this study, namely: bud-bearing root, rhizome, rhizophore, woody rhizome, stem tuber, and corms. The bud-bearing root from woody species was the dominant BBB in this system. Main conclusion The return of species that occurs in the first year after fire occurs rapidly in the first 2 months as resprouting species (primarily OS) appear in the system. Following this, the rate of return of species decreases as reseeding species (primarily NS) gradually reestablish and occupy the gaps in the dune fynbos-thicket vegetation. This study has shown that plant species in this ecosystem are adapted to fire disturbance as their populations are able to reestablish through various regeneration strategies, including resprouting from different types of BBB. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: The Eastern Cape Karoo in South Africa has been earmarked for potential Shale Gas development, which has necessitated the understanding of existing ecosystems to be quantiĄed pre-development, in order to have a baseline against which the exploration can be monitored. Termite mounds as baseline mechanisms, are known to be sensitive to ecosystem disturbance and because of their abundance in the exploration zone, have been studied as indicator species. They are both a surface and subsurface phenomena which makes them an ideal baseline monitoring mechanism. Termite mound height, basal circumference and geospatial data was collected against natural and anthropogenic factors: elevation, vegetation, water, soil, geology, human settlements and roads. Mound distributions were observed across four study sites, and seven plots, using a DJI Phantom 4 Pro drone, an aerial and ground survey. Observed mound data on the drone and aerial survey was compared to that of the ground survey. Overall, the drone survey outperformed the aerial survey in recording accurate termite mound data. This was largely attributed to the scale of the study which gave the drone a competitive advantage. It allowed for drone data to be collected at 40 m altitude with an image resolution of 2-6 cm/pixel on each plot. In addition, drone detection accuracy was improved through the ability to generate digital surface models (DSMs) through point clouds and overlaying them with orthomosaics. Considering observed mound spatial point patterns, both the drone and aerial survey were more than 50% percent consistent with the ground survey, although the drone survey detected 28.57% more accurate mound spatial point patterns than the aerial survey. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: Background: Violence against women and girls (VAWG)amongst adolescents remains a global public health problem. Globally, an estimated 24 per cent of girls aged 15-19 are reported to have experienced VAWG before the age of 20. Experience of VAWG has far reaching health and educational consequences. Thus, the prevention of VAWG needs to be a priority. In recent years, there has been an increase in web-based or online violence prevention interventions. However, these interventions are either secondary prevention interventions, or primary prevention interventions, focused on emergency or protective solutions. Current evidence indicates that group-based participatory violence prevention interventions are an important approach to the primary prevention of VAWG but there remains a gap in understanding if these interventions can be delivered online. Further, it remains unclear if co-development of group-based participatory violence prevention interventions with young people – which has been proposed to enhance contextualisation of interventions – can occur online. Goal and specific objectives: This study aimed to explore and understand the feasibility of co-developing an online group-based participatory VAWG prevention intervention for adolescents. The specific objectives of this study were (i) from the perspective of experts understand the feasibility, acceptability and challenges of a group-based participatory VAWG prevention intervention developed and delivered online, (ii) from the perspective of adolescents, understand the feasibility, acceptability and challenges of a group-based participatory VAWG prevention intervention developed and delivered online and (iii) Undertake an online co-development process of an online group-based participatory VAWG prevention intervention with adolescents. ix Methods: This qualitative study was conducted in Gqeberha (formerly known as Port Elizabeth), in the Nelson Mandela Bay municipality, Eastern Cape Province of South Africa. The study was guided by the intervention development framework: 6 Essential Steps for Quality Intervention Development (6SQuID). Data were collected online using in-depth semi-structured interviews, with 20 experts sampled through convenience and snowball strategies and 18 purposively sampled adolescents, to achieve objectives one and two. This was then followed by a co-development process with high school-going adolescents (ages 18- 19 years) to achieve objective three. In the co-development process, the candidate worked with a small group of adolescents (four adolescents) for five sessions online, over a period of two weeks. In these sessions, the co-development team engaged in discussions on sexual violence, which resulted in creation of a problem tree and populated a theory of change table. Data were transcribed in English, verbatim and analysed using thematic network analyses. Findings: Findings for the first objective about understanding from the perspective of experts the feasibility, acceptability and challenges of a group-based participatory VAWG prevention intervention developed and delivered online, showed experts identified several opportunities for these. Specifically, experts identified the potential of bringing these interventions to scale, which has been a challenge for in-person interventions, as well as accessing hard to reach groups, such as people in conflict settings, those on the move and people with limited mobility. However, experts felt there were many complex questions in the development of an online VAWG prevention intervention that needed resolving. Some of the challenges raised by experts included concerns of achieving privacy, trust, and safety online, which are central to achieving transformative communication. Experts also struggled to grapple with how a sense of community could be achieved online. There were also concerns amongst experts about material challenges such as access to devices, access to data and poor connectivity. x Interestingly, younger experts were more open to online participatory interventions than the more experienced experts. Findings for objective two “from the perspective of adolescents, understand the feasibility, acceptability and challenges of a group-based participatory VAWG prevention intervention developed and delivered online”, young people reported they were keen and open to the idea of online group-based participatory VAWG prevention interventions. They discussed how they enjoyed engaging in online groups and often experienced a sense of belonging in these groups. Yet, like the experts, school-going adolescents were concerned about safety, privacy, and trust in online groups. These concerns shaped adolescents’ willingness to disclose sensitive information online and ability to engage in open dialogue. Concern over privacy, trust and safety online also influenced adolescents’ choices over which apps to engage with, and with whom. Young people were active in thinking through and addressing how they dealt with safety, privacy and trust issues online. The third objective was “to undertake an online co-development process of an online group-based participatory VAWG prevention intervention with adolescents”, which was done over two weeks. A range of positive outcomes were identified. Firstly, young people enjoyed the level of autonomy and their depth of involvement in the process. They had come into the process anticipating being lectured to and were pleasantly surprised to find that their role was central, and they would drive the process. Secondly, adolescents were eager to be involved and appreciated being ‘heard’. This allowed for a more extensive exploration of their understanding on the topic, and development of the intervention activities that emerged. Thirdly, young people found it easy to build rapport online, both amongst each other, and with the facilitator, which made communication in the group easier. Importantly, this group of adolescents had their own laptops, or cell phones to use, and the project provided data for the young people to participate. However, there were also challenges to the process of coxi development. The central challenge was that young people and facilitator often slipped into a form of teacher-learner communication, driven by their prior histories of didactic education, which led the adolescents to ‘fearing’ to give ‘wrong’ responses. The facilitator also struggled on how to maintain adolescents’ autonomy of thought, while also incorporating ‘scientific evidence’ in the emerging intervention activities. Furthermore, the more talkative school-going adolescents took the centre stage in the discussions, with the quieter ones remaining quiet. Conclusions: The findings of this study showed that the feasibility of taking group-based participatory interventions online are possible, but this is shaped by a complex set of factors, that impact on the possibilities for transformative communication, and on the creation of safe social spaces – such as trust, privacy, safety. The central question is whether the theoretical constructs of transformative communication and safe social spaces are achievable online. A significant step in moving towards enabling transformative communication online will be addressing the issues of privacy, safety and trust. Careful training of facilitators around skills to facilitate group-based participatory VAWG prevention interventions online is also recommended. The complexities of delivering online participatory interventions require careful consideration, and this needs to be developed and thought about in conjunction with school-going adolescents (the target group), to ensure that interventions resonate with their needs and requirements. Future directions in this research field are provided. , Thesis (PhD) -- Faculty of Health Sciences, 2022

- Description: Internet connectivity, data and sensors have become increasingly important across all spheres of business and industry, especially in the mining sector. Recent years have seen deeper mining explorations as a result of the depletion of natural resources in shallow strata. Due to complex and unexpected geological conditions as well as significant ground stresses, deep stratum mining operations encounter a number of difficulties. It is essential that the mining industry be more innovative with their equipment and monitoring systems given the rise in expenses caused by energy consumption, concessions to surface integrity, worldwide freshwater shortage, as well as health and safety of miners. Any attempt to eliminate these mining consequences must start with early discovery. An effective plan to anticipate, prevent, or manage geohazards events must be in place because to these complex and unpredictably occurring geological circumstances. Due to their capacity to combine gigabits of data from remote locations within the mine to a centralized control centre, optical fiber offers a variety of distinctive advantages within the mining industry. In order to attain maximum productivity, modern and effective mining operations use enhanced control techniques and increasing mechanization. Additionally, optical fibers can be utilized in a mine to safely monitor seismic activity, methane, roof collapses, rock bursts, explosions, and dangerous underground mine settings. Multimode or multi-core fibers represent a particularly intriguing alternative for transmissions over small distances, especially for broad band local area networks like LANs, as they enable the use of affordable components. Due to the current state of these issues, there is a drive to create fiber optic communication links that can also function as distributed optical fiber sensors, where each point along the fiber can function as a continuous array of sensors. In this thesis, we suggested and experimentally demonstrated a converged solution for precise vibration sensing and high-speed data in mining applications. With wireless access for people and equipment inside cavities, the solution uses multimode fiber to link nearby mining cavities. To track vibrations and earth tremors causing rock falls, polarization-based vibration sensors over multimode fiber is used. With a modal dispersion penalty of just 1.6 dB, photonic data transmission across 100 m of multimode fiber is successfully accomplished. Successful 1.7 GHz wireless transmission across a distance of 1 m is demonstrated, and vibrations between 50 Hz and 1 kHz may be reliably detected to within 0.02 percent of the true value. , Thesis (MSc) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2022
