- Description: Introduction and background: It is estimated that as many as 12.4 of every 1 000 live births in South Africa, are premature births. Prematurity is the leading cause of death in children under five years old. Furthermore, preterm infants have an increased risk of life-long morbidities. Globally at least 2.5 million premature infants die annually due to complications or lack of proper healthcare. Prematurity and the outcomes of its complications have raised concerns globally, as greater disparity is being seen between rich and poor countries. Lack of resources, poorly skilled health care professionals and poor management of small and pre-term babies, are areas of great concern in especially in poorer countries. Identifying the causes of prematurity will consequently not only help reduce the prevalence but more so the morbidity and mortality rates caused by preterm labour. It is therefore important to highlight and understand the consequences of such a high incidence in preterm births, when identifying these risk factors. Aims and objectives: The aim of the study was to identify which risk factors are associated with the cause of prematurity at Bisho Hospital, a district hospital in central Eastern Cape, South Africa. The objectives of the study were to identify which risk factors between the full-term and pre-term group were more prevalent and therefore associated with prematurity as well as identifying which risk factors could be prevented or even treated at Bisho Hospital. Methodology: A descriptive quantitative correlation study design was used, where premature as well as full-term infants were included in the study. Data was collected by means of a questionnaire. All accessible medical notes of both the mother and infant were used as well. The questionnaire was used to establish which risk factors were most prevalent during the pregnancies of women in each group and whether these risk factors were significant contributors to prematurity. Results: A sample of fifty mothers, with prematurely born babies were included in the study, along with eighty mothers who delivered full-term babies. The four main risk factors associated with pre-term birth within this study population was: a positive 6 HIV status (p=0.022), a poor maternal nutritional status (p=0.031), mothers living far distances from their local clinic (0.041-0.024) and mothers having previously delivered a pre-term baby (p=0.009). Discussion: The four major risk factors identified in this study have shown to have significant effects on pregnancy outcomes in other studies too. Modifiable risk factors such as a poor nutritional status can be identified and addressed as a preventative measurement for prematurity. While the other three risk factors are non-modifiable, mothers who are HIV positive, have previously had a premature baby and those who live farther than 5km (or a walk of 15-30 minutes long) away from their closest clinic, should be identified as a high risk for pre-term births in current pregnancies. While addressing these risk factors is important in attempting to reduce the prevalence of prematurity, improved care of small and premature babies could help combat the growing problem of early infant deaths within this same group. Recommendation: Financial investment and analysis of current policies in the prevention and management of premature delivery should be a priority. Ensuring health care workers are regularly trained as well as equipping nurseries with the basic resources to manage a pre-term baby, can help reduce mortality and morbidity associated with prematurity. , Thesis (MA) -- Faculty of Health Sciences, 2022

- Description: The ocean is becoming the new focal point in the discourse on growth and sustainable development, both at national and international levels. Scenario planning improves the quality of the strategic conversations that organisations need to have as a position in preparing for the future. In this research, scenarios for South Africa’s ocean economy towards 2060 were developed and explored by considering the six key ocean sectors as outlined in the Operations Phakisa Strategy, namely, Marine Transport and Manufacturing, Offshore Oil and Gas Exploration, Aquaculture, Small Harbours, Coastal and Marine Tourism, Marine Protection Services and Ocean Governance. The research process was guided by Inayatullah’s six pillars and linked methods towards scenario development. Existing studies do not take into consideration the various social, technological, economic, environmental, political, legislative and ethical factors influencing the growth of the ocean economy. With the ocean increasingly being considered a new economic frontier, sustainable development has become pertinent for supporting and facilitating continued economic growth areas without compromising on environmental, social, or economic factors. Sustainable development within the ocean economy is further supported by Goal 14 of the Sustainable Development Goals, which focuses on conservation and sustainable use of the ocean, sea and marine resources. A literature review was conducted to gain a better understanding of the ocean economy, and primary data was collected through a real-time Delphi platform and semi-structured interviews. The real-time Delphi collected information on the key megatrends that continue to shape the ocean economy and key drivers and wild cards that can affect the sustainability of the key ocean economy industries. In addition, semi-structured interviews collected information on the proposed scenarios and the capacity needed in growing and promoting a sustainable ocean economy for South Africa towards 2060. A scenario matrix was developed for South Africa’s ocean economy and four scenarios and their implications were analysed. The preferred scenario was a resilient ocean economy towards 2060. The study also took a step forward with a view to provide reference to stakeholders and governments in progressing towards a possible scenario and developed an integrated vision for a sustainable ocean economy for South Africa towards 2060. This proposed vision is to ABSTRACT v mitigate against future challenges, collaborate and proactively utilise the development opportunities offered by the ocean economy. , Thesis (PhD) -- Faculty of Business and Economic science, 2022

- Description: Estuaries are historically convenient places to build industries, as it was deemed a suitable place to dispose of large quantities of urban and industrial waste into the ocean. At the time it was judged to be appropriate, as rivers can transport and deposit waste into the ocean, which was considered so vast that it is insurmountable. Therefore, metal pollution in estuaries is a well-known occurrence. Coastal wetlands play an important role in the cycling of metals, and act as effective metal sinks. They provide an important ecosystem service acting as accumulators and phytostabilisers, which make toxic levels of the metals unavailable to the rest of the food chain. The overall aim of this study was to assess the metal pollution in the salt marsh (Salicornia tegetaria and Spartina maritima) and seagrass (Zostera capensis) of the heavily developed Swartkops Estuary. Assessing the metals in the estuary will provide information on effective environmental management strategies. Metal concentrations were measured in the rhizosediment of the three wetland plants, bare sediment, and in the tissues (leaves, shoots, and roots) of the selected plant species. Sampling occurred during one seasonal cycle (2019-2020), and in 5 sites along the middle and lower reaches of the estuary. Metal concentrations were not the highest closest to the point sources in the middle reaches, but the metals rather accumulated downstream in Site 3 (Tiger Bay launch site close to the WwTW) and Site 4 (Tippers’ Creek), which were depositional sites. Although these two sites generally displayed the highest metal concentrations, they also had the most seasonal fluctuations in their metal concentrations and sediment characteristics. Flushing events in spring/summer were likely the determining factor of these fluctuations. The mouth of the estuary (Site 5) consistently had much lower metal concentrations, with distinctly more sandy, low organic content sediment, due to marine-influenced flushing. Thus, spatial differences were distinct in the estuary, however seasonal differences did not play an important role in the metal concentrations, indicating that seasonal sampling was not as important as sampling in different sites. Assessing the metal concentrations in different rhizosediment gave important insights on intertidal accumulation and contrasted with the unvegetated (bare) sediment. The metals generally accumulated more, higher up the intertidal range, due to less frequent tidal inundation and flushing — so that metal accumulated in the vegetation in the following order: Z. capensis > S. maritima > S. tegetaria. Moreover, unvegetated (bare sediment) showed much lower metal concentrations compared to the rhizosediment, indicating that the vegetation trapped small particles, and changes the physical environment to concentrate metals in their rhizosphere. Lastly, the plant species all displayed good accumulation of metals in their roots, while Z. capensis also showed remarkable uptake to its leaves. The study identified S. maritima and S. tegetaria as good phytostabilisers, particularly the latter with its vi high metal stocks and slow root turnover rate. The compartmentalization in these plants were unique to each species, corroborating previous assessments that compartmentalization cannot be compared between similar life forms and genera. These results contribute to local and international research on biogeochemistry in wetlands, and assessment of pollution in developed estuaries. Of note is Z. capensis, an endemic Southern African species, which has not been analysed for compartmentalization of metals before. All three of the studied species have potential as metal accumulators, and therefore a sink of metals. They localize the metals, limiting bioaccumulation to the rest of the food chain, which reduces the ecotoxic effect of metals in the environment. Higher accumulation in vegetated (rhizosediment) over bare sediment, make these habitats valuable metal sinks. This increases their importance in estuaries receiving high pollution loads, and they should be prioritized in conservation efforts. Two sites within the Swartkops Estuary, Tippers’ Creek (Site 4) and the Launch Site (Site 3), are potential sites for long-term monitoring due their capacity to trap and accumulate metals. The results of this study will inform local management on the state of metals in the Swartkops Estuary, providing crucial information on the importance of preserving local wetlands for the purpose of regulating toxic levels of metals in the ecosystem. , Thesis (MSc) -- Faculty of Science, Botany, 2022

- Description: Food insecurity is a prevailing problem and according to a report released in 2019 by the Food and Agriculture Organization (FAO), about 2 billion people in the world experience moderate or severe food insecurity (FAO, IFAD, UNICEF, WFP and WHO 2019: vii). Consequently, if we are to make a significant change in these statistics, the actions taken to “tackle these troubling trends will have to be bolder, not only in scale but also in terms of multisectoral collaboration” (2019: viii). It is against this backdrop that this study will explore the discursive landscape around four social media applications - OLIO, Too Good To Go (TGTG), KHULA and OneFarm Share - working to fight food waste, tackle food insecurity and reimagine the food system. This study is situated in the field of media studies and adopts a qualitative approach, with hermeneutics as the specific research strategy which “[seeks] understanding, rather than to offer explanation” (Kinsella 2006: n.p). This study maps the development of media effect theories over the years and explores where it is today, drawing on key thinkers in the space of new media including Lister, Manovich and Castells. This is followed by a discussion of food insecurity globally, and then locally within a South African context, as well as through the lens of ecosocialism drawing on voices such as Kovel and Löwy. This will lead to a content analysis of the four selected applications exploring the discursive landscape around each, and what similarities and disparities emerge. , Thesis (MA) -- Faculty of Humanities, Language, Media and Communications, 2022

- Description: The study explored smallholder farmers’ perceptions of drought tolerant maize in Cork village, Mpumalanga Province. The study analysed the factors that pushed smallholder farmers to grow drought tolerant maize crops. It examined the maize varieties farmers grow and investigated the benefits and the challenges of growing drought tolerant maize crops. The review of literature found that no similar studies have explored the smallholder farmer’s perceptions of drought tolerant maize. The study was guided by a pragmatic research philosophy and it used mixed research methodology to collect data on the research objectives of the study. Purposive sampling was used to select primary respondents and snowball sampling was used to select key informants. The study found that drought and agro-ecological conditions have pushed farmers to grow drought tolerant maize crops and these crops are improving farmer’s agricultural yields and food security. However, drought tolerant maize crop varieties are inaccessible at shops and they are very expensive to buy given the socio-economic status of people living in rural areas of this village. The study recommends that the price of drought tolerant maize seed varieties should be subsidised, availability and easily accessibility to the market should be improved and future studies could investigate the contribution of drought tolerant maize varieties on household food security. , Thesis (MA) -- Faculty of Business and Economic science, 2022

- Description: The influence of urbanization and industrialization on natural resources results in complex water resource management. In South Africa, there has been escalating rural-urban migration, a growing population in urban areas, and the mushrooming of informal settlements in cities over the last five decades. In the pursuit of protecting water resources, these contextual realities create a significant challenge to policymakers, planners, and implementers. Due to rapid population growth, climate change, recent droughts, and growing competition among agricultural, industrial, commercial, environmental, and domestic sectors, water resources are presently under severe stress in South Africa. This situation necessitates the effective management of water resources. This study completed a situational assessment for the Swartkops Catchment to examine the extent of pollution, mapped sources of pollution, investigated water quality governance and identified hot spot areas to provide the foundation for effective and efficient catchment management. To determine the current water quality status of the Swartkops Catchment, this current study investigated spatial and temporal variation in physico-chemical parameters, nutrients, and faecal bacteria. This study applied a mixed-method research design using semi-structured interviews and focus groups discussions as data collection methods to investigate the water quality governance of the Swartkops Catchment. Following the situational assessment of the Swartkops Catchment, the effectiveness of applying innovative smart catchment practices to improve water quality was investigated. The word smart in this context refers to innovative mechanisms that will ensure effective and efficient water resources management. The PHP scripting language (Hypertext Preprocessor), Android studio, Wampserver, and JavaScript were used to develop the Water Use Screening System (WUSS) and Pollution Incident Reporting System (PRS). In South Africa, stormwater infrastructure suffers from unsustainable utilization. Stormwater systems discharge into many of the country‘s rivers and estuaries, including Swartkops, leading to water quality degradation. To improve the Recommended Ecological Category (REC) of the Swartkops Estuary to Category C, drivers that contribute to poor water quality must be understood to inform appropriate management interventions. Results from sampling in Markman Canal were compared with historical water quality data. The present study showed that the Markman Canal contributed faecal bacteria, nutrients, and trace metals to the Swartkops Estuary. The Markman Canal was the greatest source of trace metals to the Swartkops Estuary compared to the other point sources entering the estuary. The results show that arsenic and mercury levels in the Markman Canal and the Swartkops Estuary were higher than that previously measured. Iron and copper concentrations were higher in the Markman Canal whereas only copper increased in the Swartkops Estuary. , Thesis (PhD) -- Faculty of Science, School of Environmental Sciences, 2022

The Markman Canal was the greatest source of trace metals to the Swartkops Estuary compared to the other point sources entering the estuary. The results show that arsenic and mercury levels in the Markman Canal and the Swartkops Estuary were higher than that previously measured. Iron and copper concentrations were higher in the Markman Canal whereas only copper increased in the Swartkops Estuary. , Thesis (PhD) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: The South African Labour Relations Act 66 of 1995 provides for the establishment of statutory, yet voluntary, employee participation structures in the form of Workplace Forums. These Workplace Forums were modelled on the system of German Works Councils. The establishment of Workplace Forums solely lies with a representative trade union in a workplace of more than 100 employees. Trade unions have not been enthusiastic about the idea of Workplace Forums, this is because they view these structures as a mechanism that undermines collective bargaining due to the limitations that come with consultation as a process in decision-making. Trade unions would rather have powers of negotiation, for which Workplace Forums do not cater. Consequently, very few Workplace Forums have been established in South Africa. In the South African Municipal sector, there are Local Labour Forums which are solely for employee participation over and above matters reserved for collective bargaining in the South African Local Government Bargaining Council. Local Labour Forums have powers of consultation and negotiation on matters that affect labour relations and employees in the municipality. Local Labour Forums became an area of interest because of the limited opportunities in South Africa to study Workplace Forums. The aim of the study was to investigate Local Labour Forums as an example of Workplace Forums as employee participation structures. Therefore, the main research question was: how are these Local Labour Forums structured, what are the details of their functioning and what are the perceptions of the participants in these structures of their influence on performance in the workplace? The aim was translated into four objectives. The first objective was to explore the structure and functioning of Local Labour Forums. The second objective was to explore the perception of the parties to Local Labour Forums, namely, councillors, managers, and unions regarding their relationships. The third objective was to explore the agreements concluded by the parties and their levels of satisfaction with the agreements. The fourth objective was to explore the perception of the parties to Local Labour Forums of the contribution of the Local Labour Forums to the service delivery of the municipality. This was an exploratory and descriptive qualitative study. The population of the study was the Local Labour Forums in two metropolitans, six districts and thirty-one Eastern iv Cape municipalities. The sampling method used was non-probability purposive sampling. Primary data was sourced using both interview guidelines and a short survey questionnaire. The data obtained was transcribed and thematically analysed using Tesch’s (1990) content analysis as a method. The findings of the study indicated that while both Workplace Forums and Local Labour Forums are workplace committees, Local Labour Forums operate differently from Workplace Forums in terms of their structure and functioning. A major difference between these two structures is that Local Labour Forums are joint consultation committees, comprising of both the employer and employee representatives; whereas Workplace Forums are structures which only comprise of employees who then meet with the employer on a regular basis. The processes used for both these structures are somewhat different because Local Labour Forums have powers of consultation and negotiation, whereas Workplace Forums only have the powers to consult and jointly make decisions, not to negotiate. Adding to these differences is that Local Labour Forums have powers to establish subcommittees who will report back to this particular structure, whereas nothing about subcommittees is mentioned for Workplace Forums. In terms of the findings gathered on Local Labour Forums based on the abovementioned objectives, it was found that the establishment of these municipal structures are mandated by the South African Local Government Bargaining Council. Local Labour forums discuss matters of mutual interest which pertain to their respective municipalities. The parties to the Local Labour Forums are from both the employer and employee components. The employer component consists of senior municipal management/directorates and councillors. The employee component consists of the two in-house trade unions, the South African Municipal Workers’ Union and the Independent Municipal and Allied Trade Union. The fact that these parties are from different backgrounds in terms of conscience does not affect the relationships and agreements of the forum, because they are all about what is good for the structure. When it comes to performance of the Local Labour Forum, it was discovered that these structures are not directly involved in delivering services to the municipalities, but the decisions taken influence how the municipalities deliver their services. , Thesis (MA) -- Faculty Faculty of Business and Economic science, 2022

- Description: Accessibility to healthcare refers to the availability, or the provision of healthcare-byhealthcare professionals and stakeholders and individuals' ability to obtain care and treatment. It affects overall physical, social, and mental health; disease and disability prevention; detection and treatment of health conditions; standard of living; preventable death; and life expectancy, and it is crucial to the performance of health care systems around the world. If healthcare services are available and are in sufficient supply, people will be able to seek health care, and a population will have access to services. The leading cause of death globally is Tuberculosis (TB) and South Africa is amongst the top 5 countries most affected by TB. This is aggravated by high HIV/AIDS statistics. Children belowthe age of 4, between the ages of 4- 15, and women and men of working ages are highly affected by TB and it is the primary cause of death in these groups in the Ngaka Modiri Molema District. This study used study tools like Spatial Modelling, Geographic Information Systems and software like ArcGIS 10.5, TerrSet IDRISI 18.30, and secondary data from the North West Departmentof Health (Tier.net &DHIS) and also TB patients’ home addresses to investigate the accessibility of TB treatment in Ngaka Modiri Molema, in order to spatially visualize the distribution of a communicable disease like TB and public healthcare facilities in the Ngaka Modiri Molema (NMM) District and suggest optimum sites for hospital facilities. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: Growth economists identified that current failures and successes of economies can be traced far in their histories. The Unified Growth Model has been developed to analyse the process of development. Economic researchers have developed and identified ‘deep roots’ variables that elaborate modern growth, institutions and development. These variables include State Antiquity and Early agricultural transition. The study is an examination of the effects of State Antiquity and Early agricultural transition in the 54 African economies. The study examines these effects employing the following years: 1990, 1995, 2000, 2005, 2010, 2015, and 2020. The study employs econometric models namely, Ordinary Least Squares, Ridge and Lasso regularization models to examine the effects of these deep root variables. The study borrows baseline regressions from the works of Bockstette, Chanda and Putterman (2002), Putterman and Weil (2010) and Borcan, Olsson and Putterman (2018). This study, to the best of our knowledge, is the first to empirically examine the effects of State Antiquity and Early agricultural transition in Africa. The results of the study suggest that African economies that have low level of state antiquity experience a positive effect on modern economic growth and development whilst African economies with high levels of state antiquity experience negative effect on modern economic growth and development. The results also suggest that African economies that transition at a later stage toward agriculture experience a positive effect on modern economic growth and development. The implications of these findings indicate that state antiquity and early agricultural transition influence modern economic development only when states have reached a certain level. Countries that transitioned early towards agriculture experience a negative effect on modern economic growth and development depicting a reversal of fortune. The study recommends that the implementation of polices should corelate with the state experience of the specific economy. , Thesis (M.Com.) -- Faculty of Business and Economic Sciences, School of Economics, Development & Tourism, 2022

- Description: The purpose of the study was to investigate the current status of physical activity (PA) and physical fitness (PF) of intermediate-phase schoolchildren from marginalised communities in Port Elizabeth. A total of 985 schoolchildren (n=505 boys, n=474 girls) aged 8 to 16 years, from eight quintile 3 government schools participated in this study. These schools included four schools from the Township area and four from the Northern areas in Port Elizabeth. The tests included in the study were PA (Actigraph accelerometer), PF (20 m shuttle run test and grip strength), and body composition (body mass index and body fat percentage). Results showed that girls had higher body mass index (BMI) and body fat percentage (BF%), lower VO2max, less time spent on average per day on moderate to vigorous physical activity (MVPA) and lower grip strength (GS) as compared to boys (p0.05). No significant differences were found between the two geographic areas with regards to VO2max, GS, BMI and BF% (p>0.05). However, when confounding variables were considered, there was a significant difference in the BMI (p=0.0007), BF% (p=0.0003) and GS (p=0.0004) of the children from the two geographic areas. A negative correlation was found between VO2max and BMI A positive correlation was found between VO2max and MVPA . Overall, girls seem to be more at risk than boys for future non communicable diseases. These findings highlight the importance of promoting PA and monitored PF in children, and particularly in girls from marginalised communities. , Thesis (MA) -- Faculty of Health Sciences, School of lifestyle Sciences, 2022

- Description: The continuous growth of mankind has not been considerate to the environment. The release of millions of tonnes of toxic heavy metal cations and anionic species through industrial, mining, agricultural, and electronic dumping has led to disease and, in many instances, death. This is usually suffered by low-income informal populations residing in third world countries. Moreover, many unnecessary deaths of children are becoming more prevalent because of consumption and contact with contaminated water, agricultural, and animal sources. Bioaccumulation of these toxic species in fish, plants, and animals, inevitably make their way back to the unaware general population. As growth by mining, agriculture, and electronics are indeed vital aspects of human development, the negative side effects of these activities usually continue unregulated. Therefore, as these processes are set to continue until more stringent regulatory processes are put into legislature; low-cost, sensitive, selective organic based sensors are a step in the right direction towards highlighting the need for environmental restoration and remediation; whilst also aiming to preventing unnecessary disease and death in the process. Herein, coumarin derived small-molecule fluorescent and colorimetric sensors for the quantitative and qualitative assessment of cationic and anionic species in aqueous and organic media are described. Ten fluorescent sensors supporting 1,4-disubstituted triazolyl moieties were synthesized according to Cu(I)-catalyzed azide-alkyne cycloaddition “click” reactions. These sensors were screened for their cationic and anionic affinities in a variety of solvent systems. Majority of the sensors responded well towards Fe3+, characterized by a strong fluorescent quenching response with a good degree of sensitivity and selectivity. Selected sensors were further investigated for their affinities towards anionic species; however, they did not display the same degree of selectivity or sensitivity towards these chosen anions. Titration studies of selected sensors with Fe3+ were able to be used towards determining the modes of fluorescent quenching; the photophysical mechanisms by which quenching occurs; stoichiometric binding ratios, association constants, and the number of coordination sites present between the sensors and Fe3+. Reversibility studies of the sensor-metal complex was investigated with EDTA. Partial reversibility was achieved for the chosen sensors with Fe3+. Hydrogen potential studies further described the application of these sensors over a good pH range. The binding site between the sensors and Fe3+ was investigated by NMR studies. , Thesis (PhD) -- Faculty of Science, School of Biomecular and Chemical Sciences, 2022

Reversibility studies of the sensor-metal complex was investigated with EDTA. Partial reversibility was achieved for the chosen sensors with Fe3+. Hydrogen potential studies further described the application of these sensors over a good pH range. The binding site between the sensors and Fe3+ was investigated by NMR studies. , Thesis (PhD) -- Faculty of Science, School of Biomecular and Chemical Sciences, 2022

- Description: This study focuses on the development of a synthetic version of the cannabinoid cannabigerol (CBG) through continuous flow systems. The compound has exhibited antibiotic properties that have been proven to be a potent killer of gram-positive methicillin-resistant Staphylococcus aureus that drive repeat infections. The cannabinoid kills the superbug by disrupting the cell wall integrity of cells that are drug resistant. Research suggests that CBG is not effective against gram-negative multi-drug resistant bacteria. However, when CBG is administered with polymyxin B, an antibiotic that disrupts the outer membrane of gram-negative bacteria the cannabinoid compound wipes out the drug-resistant gram-negative bacteria, thus revealing the extensive medicinal potential of cannabigerol. Cannabinoids, such as CBG, are present in low yields in the plant, depending on the extraction method, usually less than 5% in most strains. Natural medicines have a low amount of active ingredients due to the lab intensive and time-consuming extraction and isolation process; this has hindered the application of natural products in drug development. A major health concern of the human consumption of cannabis plant extracted cannabinoids is that the plant may be contaminated with microbes, heavy metals and pesticides due to the lack of regulation. Thus, it is proposed that these cannabinoids are synthetically produced through the integration of microfluidic technology, eliminating the presence of pesticides, microbes and heavy metals. The proposed method would even further speed up the rate of production at a lowered cost, produce greater yields of the product compared to extraction procedures / in batch reactions and improve the purity of cannabinoid compounds. This was achieved in flow chemistry whereby the key intermediates (olivetol, a derivative of methyl 6-n-pentyl-2-hydroxy-4-oxo-cyclohex 2-ene-l-carboxylate and cannabigerol) were produced at high conversions (67%, 100% and 34% respectively) in LTF glass microreactors. Cannabigerol was successfully synthesized in flow at high yields compared to literature, however, it was further discovered that the formation of side products was a hindrance to further improvement of the obtained yield in flow. , Thesis (MSc) -- Faculty of Science, School of Biomecular and Chemical Sciences, 2022

- Description: This study highlighted the importance of technical skills, knowledge transfer and its drivers. Organisations face a dilemma when incumbent tacit knowledge owners vacate employment without transferring invaluable intellectual property to other stakeholders (Khumalo, 2012). Once this knowledge is lost, it may be impossible to recover and difficult to hide from competitors (De Long, 2004). Knowledge transfer among employees is a critical enabler of organisational learning. In the context of the South African automotive industry, the volatility of the industry has seen many Original Equipment Manufacturers (OEM) and their suppliers shedding jobs. Furthermore, the replacement of the old automotive training board by the Sector of Education and Training (SETA) has created more complex challenges. Automotive companies are struggling to absorb the financial burden that comes with training skills transfer, due to the reduced workforce that is overloaded by work to cope in the current economic climate. The drivers of technical skills and knowledge transfer were investigated in a particular automotive company in Port Elizabeth, South Africa. A mail survey was directed to 168 technical employees in an automotive manufacturing plant. The survey tested the dependent variable (technical skills and knowledge transfer), and independent variables were its drivers (management of scarce skills, succession planning, trainee characteristics, training design and work environment). The survey had 50 questionnaire items. Statistical analysis was used to analyse the research questions through descriptive statistics, Pearson correlation and multiple regression analysis. The empirical results found that all of the independent variables showed positive correlations with the dependent variable, however succession planning, followed by work environment showed the most significant relationship with technical skills and knowledge transfer in an automotive organisation. , Thesis (MA) -- Faculty of Business and Economic science, 2022

Section 191 determines these time frames by stating that an employee must refer their alleged unfair dismissal to the CCMA within 30 days or 90 days when a dispute relates to an unfair labour practice in accordance with section 191(1)(b)(ii) of the LRA.5 The rationale behind these time frames was outlined in the Constitutional Court (CC) judgement of Toyota SA Motors (Pty) Ltd v CCMA,6 as a means to bring about the expeditious resolution of labour disputes which by their nature, require speedy resolution. , Thesis (L.L.M.) -- Faculty of Law, Mercantile Law, 2022

- Description: The aim was to assess the development policies affecting the development of Makana Municipality. Development policies exist to foster and improve the lives of the people, for example through job creation, poverty alleviation, improvement of infrastructure. Therefore, the neglect of Makana Municipality to deliver such services is a denial of basic human development and opportunities for people to lead a long healthy life and get to enjoy a decent level of dignity, freedom, self-esteem, respect inter alia. The municipality has played a role in how development has been delayed. The recent court ruling is the evidence of that. The high court in Grahamstown dissolved the municipality in January and the judgement was perceived as a historical verdict in the history of local government. Makana municipality has deteriorating service levels and it has been like that for few years now. The livelihoods of the people of Makana have been affected as the dissatisfaction with services continues. This study highlighted the importance of good governance and appropriate policies to respond to issues are for development and to address different challenges. Moreover, one of the strong bases for successful local government is good leadership, that responds to people’s needs strategically and technically. The research has found the slow pace in development has a negative impact in the fight against poverty and unemployment in the municipality. Therefore, serious interventions strategies to improve the pace of service delivery in the local municipality needs to enforce responsibility and accountability. Local Government is the sphere that is the closest to the people and responsible for delivering services as stipulated in the Constitution of the Republic of South Africa (1996). Thus, when a municipality fails to provide services, the citizens are the ones who should hold the government accountable and demand services. Municipalities have a developmental role that they need to play and fulfil, and this is stated in the Constitution as follows. “Developmental local government is local government committed to working with citizens and groups within the community to find sustainable ways to meet their social, vi economic and material needs and improve the quality of their lives” (Republic of South Africa, 1996, section 153). , Thesis (MA) -- Faculty of Business and Economic science, 2022

- Description: Sexual violence affects countries globally and statistics show the prevalence of sexual violence is on the rise. The rationale for the study linked the prevalence of sexual violence in South Africa, therefore the study explores two aspects: 1. the construct of ‘sexual consent; 2. how men perceive sexual consent and rape in existing literature. A qualitative integrative synthesis was utilised as a research design. The data used in the study was sourced from various databases and content analysis was employed to analyse the data. This research thesis reviewed the conceptualisation of consent and male views on rape. In legal terms consent is defined as an agreement that includes choice, and freedom and capacity to make this choice; consent is also vitiated under certain circumstances. Civilians recognise consent as a mutual willingness that can be revoked and lacks resistance both verbally and nonverbally. Academic literature on male perceptions yielded four themes: Tacit knowledge, Ambiguity, Masculinity and Alcohol consumption. The analysis found that men understand the concepts of consent; their worldviews however contribute to them considering whether sexual interactions are consensual or non-consensual. The literature suggests that, considering the influence of patriarchy in South African society, the men referred hold high rape myth acceptance beliefs and have a sense of entitlement to female bodies. , Thesis (MA) -- Faculty of Health Sciences, 2022

- Description: Although African governments have a significant role to perform in developing the continent, International financial institutions (IFIs) also perform a dominant role in economic development but their role in African development is often viewed as controversial and contradictory. In the 20th century, the World Bank and the IMF were vital IFIs that characterised global policies that regulated global economies, subjecting weaker economies to SAP. This necessitated African states to borrow money to ensure stabilisation, liberalisation, deregulation and the privatisation of most sectors. This study econometrically examined the impact of foreign aid on economic development in SADC countries. Panel regression techniques were employed to analyse the contribution of international financial institutions to economic development in SADC countries. The results indicated that there is an insignificant relationship between foreign aid and economic development, which implies that foreign aid does not contribute to economic development in SADC countries. Based on this finding, the study recommends that Southern African Governments find ways of financing development that guarantee economic growth. , Thesis (MA) -- Faculty of Business and Economic science , 2022
