- Description: Lithium-ion technology takes the lead in electric mobility systems, resulting in an increase in the global demand for Li-ion batteries; however, these batteries are associated with numerous safety concerns. Additionally, there are high costs, high energy and power issues which are some of its key limitations. Research efforts are focused on overcoming these obstacles, with different approaches being explored, such as the investigation of more stable salts, modification of active materials and organic solvents, and the use of electrolyte additives. This study focused specifically on electrolyte additives since the electrolyte is one of the most unstable components of the battery. The electrolyte’s decomposition is one of the reactions that occur inside a battery, which may occur due to overcharging or due to an internal short circuit, amongst others. The electrolyte’s decomposition occurs at the early stages of the thermal runaway process and forms part of the reactions that lead to fires and explosions. Thus, this research aims to develop suitable electrolyte additives to improve the safety aspects of Li-ion batteries. Flame retardant additives show great promise in reducing the flammability of the electrolyte in Li-ion batteries, since they serve to suppress the chemical reactions associated with battery ignition. They retard the fires by scavenging the active radical species formed during the decomposition reaction. In this study, the use of flame retardants was investigated. Flame retardant additives have shown to have flame impeding properties inside a battery; however, their direct addition to the electrolyte tends to cause adverse effects on the ionic conductivity and electrochemical performance of the cells. This study investigated an alternative option - the option to microencapsulate such additives into a neutral compound to ensure that the flame retardant has minimal/no effect on the performance of the battery. This investigation looked at tris(2-butoxyethyl) phosphate (TBP) and bis(2,2,2-trifluoroethyl) methylphosphonate (BFP) as flame retardant additives for the electrolyte. The TBP and BFP flame retardants were microencapsulated in poly(urea formaldehyde) (PUF) coating material via in situ polymerization method. The capsules were characterized using various analytical techniques - to prove it was successfully encapsulated. Electrochemical studies were further done on the capsules and neat flame retardants inside a coin cell. Self-extinguishing time (SET), which is the flammability test, proved that the additives have flame retarding abilities. Opto-digital microscopy (DSX) and scanning electron microscopy (SEM) did confirm the spherical shape of the microcapsules, where SEM also showed the smooth outer layer of the microcapsules and its hollow inner side. Fourier transform infrared spectroscopy (FTIR) proved the presence of the TBP and BFP inside the PUF resin by showing that the chemical composition of microcapsules consisted of both the PUF and flame retardant additives. Simultaneous DSC-TGA (DST) was also performed which showed that the microcapsules were stable before 200 °C, which indicates it would not decompose before the thermal runaway events are occurring. TGA analysis did show that the microcapsules underwent multiple decomposition steps upon heating. Additionally, 31P nuclear magnetic resonance (NMR) was used to quantify the amount of flame retardants additives encapsulated inside PUF shell, and also confirmed the stability of the microcapsules for one month in the electrolyte and at temperatures up to 200 °C. The ionic conductivity was vastly decreased when the flame retardants were added directly to the electrolyte. However, adding the flame retardants in a form of capsules had minimal effect on the ionic conductivity. The cycle capacities of the capsules were also improved when the capsules were added to the cell compared to that of neat flame retardants. The same effect was also noticed when doing Electrochemical Impedance Spectroscopy (EIS). This shows that microencapsulation improves the resistance of the cell caused by the flame retardant in comparison to when added directly to the electrolyte of the cell. , Thesis (MSC) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2022

- Description: South Africa is confronted with a skewed economy along racial lines through a history of colonialism and apartheid. The laws of government have tried to include companies in advancing social cohesion and in dealing with issues of the historical exclusion of African communities from the mainstream economy. With the advent of democracy, the government has been faced with the mammoth task of driving transformation and inclusion in various sectors of the economy. Various pieces of legislation have been promulgated to give effect to this ideal. The Broad Based Black Economic Empowerment (BBBEE) Act with its associated regulations has Enterprise and Supplier development (ESD) as one of the five pillars underpinning the targeted areas for transformation in companies. Enterprise development is a key contributor to companies achieving a good score card rating as determined by the government of South Africa for various industries. This scoring also has advantages in terms of accessing government incentives as well as procurement opportunities for businesses with government. Companies therefore deploy capital for the development of businesses within their supply chains and also any other businesses whether or not they do business with them. This process of enterprise development funding is largely undefined and sees companies use various methods and criteria to deploy the capital with a myriad of outcomes all of which vary depending on the area of interest. The primary intent of the enterprise development funds is to create patient, free and sometimes affordable capital for the growth and sustainability of previously disadvantaged businesses in the South African context. Industries like manufacturing, in their nature are capital intensive and require huge capital outlays which then become a barrier to entry particularly for previously disadvantaged groupings like black people. The aim of the study is to identify key determinants that can unlock the growth and sustainability of black owned SMMEs in the manufacturing sector and also to understand the environment in which they operate. It is intended to assist policy makers, enterprise development practitioners, regulators and the beneficiaries of enterprise development on what can be done to ensure that this critical programme achieves its desired outcome. , Thesis (MA) -- Faculty of Business and Economic science, 2022

- Description: The increasing financial liberalisation since the collapse of the Bretton Woods regime in the 1970s has made exchange rates in both developing and industrialised countries unpredictable. As a result, both researchers and policymakers have become increasingly interested in the consequences and causes of exchange rate volatility. Fluctuations in foreign exchange rates may be a significant source of concern for banking institutions. In the worst case, significant losses in foreign exchange could result in financial crises, apart from causing significant constraints on the revenue growth of banks. This research study sought to investigate the volatility of exchange rates in South Africa and how this volatility affects commercial banks’ performance. The study was guided by both theoretical and empirical literature to achieve its main objective. This investigation is rooted in two theories: The Purchasing Power Parity theory, and the International Fishers Effect theory. The purchasing power parity (PPP) theory expresses that, homogeneous goods, in various countries, cost equally in similar countries when estimated in terms of the same currency (Brunnermeier and Pedersen, 2009). The theory postulates that if two homogeneous goods are traded at various costs in various countries, the arbitrage opportunity would be exploited, which prompts convergence of the deviations from Purchasing Power Parity towards equilibrium without arbitrage costs. The International Fisher Effect stipulates that the distinction in returns between two countries is simply equivalent to the distinction in inflation rates (Ross, Westerfield, Jaffe, & Jordan, 2008). The theory proposes that foreign currencies with relatively high-interest rates would depreciate on grounds that the high nominal interest rates reflect anticipated inflation. The nominal interest rates would likewise fuse the risk of an investment (Majok, 2015). The research adopts two econometric models namely: The EGARCH technique in modelling volatility, and the NARDL method to investigate the relationship. Results from the NARDL model reveal the occurrence of a long-run relationship between exchange rate volatility and bank performance. However, the influence of exchange rate on bank performance varies, depending on the type of proxy employed to measure bank performance. Four commercial banks revealed evidence of cointegration among the variables in the model in the short run, and indicated the v | P a g e speed of adjustment in the short run towards the long run. Nedbank’s return on equity, however, has an insignificant short-run relationship. Therefore, the study recommends that management of banks should place a greater emphasis on assessing and overseeing economic exposure, and factoring this into strategies in decision making. , Thesis (MA) -- Faculty of Business and Economic science, 2022

- Description: While there is extensive research exploring the influence of a client’s cultural beliefs on the therapeutic process; there is still a scarcity of information on how the cultural beliefs held by a psychologist may affect or influence the therapeutic process. Psychologists are trained to work with clients objectively by suspending their own beliefs, ideas, and values. Despite this, it would be interesting to explore how South African psychologists’ personal belief systems are navigated within the therapeutic space. Given the diversity of cultures within the South African context, it becomes important to explore and understand psychologists’ cultural belief systems, as they may influence the therapeutic relationship but to also, understand how they assimilate these belief systems into the therapeutic relationships with diverse clients. Drawing on the qualitative methodology, the study sought to draw participants using a purposive sampling technique. Participants were sourced through different databases, such as the Eastern Cape database of registered and practicing psychologists. Participants who agreed to partake in the study were sent an email with the interview schedule and the link to either MS Teams or Zoom, depending on their preference. The collected data was transcribed and then analysed using thematic analysis through which three themes and six sub-themes were identified and discussed. The identified themes are as follows; 1) Culture as perceived by psychologists, 2) Cultural beliefs in therapy and, 3) The therapeutic alliance. The study found that shared cultural beliefs between psychologists and clients facilitated rapport building. It allowed the therapeutic process to move in a positive direction. The study applied the principles of ethics and trustworthiness. , Thesis (MA) -- Faculty of Health Sciences, 2022

- Description: The challenges faced by novice teachers have been widely discussed in the last decade (Caspersen & Raaen, 2014; Burkman, 2012). It is believed that the first year of teaching is found to be exceedingly challenging to the novice teacher due to the complex demands of the profession, as well as a result of a lack of training and induction into the work environment (Burkman, 2012). Researchers highlight that some of the many challenges that novice teachers experience are shortcomings in curricular planning, classroom management and discipline, instructional techniques, access to materials, and dealing with parents (Burkman, 2012). These challenges, along with feelings of inadequacy due to lack of experience in the working world, often have a negative effect on novice teachers and their ability to cope, subsequently resulting in high stress levels and burnout (Caspersen & Raaen, 2014). This qualitative study incorporated an interpretivist paradigm and used both semistructured interviews and a focus group discussion to explore the adaptation challenges experienced by novice Foundation Phase teachers in the Nelson Mandela Metropole. Grossman‟s Teacher Knowledge Theory and Vygotsky‟s Social Constructivist Theory were used to frame and make meaning of the findings of this study. The findings of this study indicate that novice teachers experience a range of challenges upon entering the working world. The numerous factors influencing these challenges experienced by novices include: the work environment; prior training and education; personal knowledge, values and attitudes toward teaching; and professional and social support received within the workplace. These findings were used to formulate guidelines to help support novice teachers in their adaptation from university to the professional work environment. , Thesis (MEd) -- Faculty of Education, 2022

- Description: Background: Field hockey is a stick and ball team sport which is comprised of technical and tactical components and requires elevated physical conditioning. Due to the intermittent and complex nature of field hockey, it has become increasingly difficult for coaches to accurately measure the players hockey specific fitness levels. For this reason, various fitness tests have been developed over the years. However, some of the fitness tests utilised to this day do not incorporate movements similar to match situations, and therefore, do not stress the same energy systems in a similar manner to match-play. Hence, the INTER test and Dynamic Yo-Yo test are being utilised in the current study as they incorporate similar movements seen in match-play, and they incorporate varying rest periods. The INTER test is a test that incorporates shuttles, maximal sprints and agility movements. Whereas the Dynamic Yo-Yo test only incorporates shuttles running with differing changes in angles. However, both of these tests have previously only been used in a soccer context, therefore, the results obtained were compared to soccer specific data. Match-related data was compared to current field hockey data. Aim and Objectives: The main aim of the research study was to determine whether the INTER test and the Dynamic Yo-Yo test correlate with match-related physiological demands and physical performance. There were three main objectives of the study. First, to determine and describe the physical and physiological responses in selected cohort off hockey players during match-play, the INTER test and the Dynamic Yo-Yo test. Second, to run correlations between the two field tests and match-play to identify relationships. Third was to identify the differences between the two field tests. Methods: Using a combination of purposive and convenience sampling, a total of 20 field hockey players from the Eastern Cape Premier Hockey League voluntarily participated in the study (age: 22.25 ± 3.16 years; height: 167.3 ± 2.61cm; weight: 59.4 ± 3.87). The participants were monitored during the INTER test, Dynamic Yo-Yo test and the field hockey matches. The following physiological and physical variables were monitored: heart rate, breathing rate, distance and speed. The participants were given a minimum of 24 hours recovery time between field tests and matches to ensure fatigue did not impact results. The monitoring during the field tests and match-play was done by all participants wearing the Zephyr BioHarness and QStarz global positioning system. VI Results: The mean distance achieved in the INTER test and the Dynamic Yo-Yo test both produced a statistically strong relationship to the mean distance achieved in the matches (r=0.82, p=0.000). The time spent in the INTER test and the Dynamic Yo-Yo test compared to the time spent in match-play showed a very weak correlation (r=0.19; r=-0.08). Both the mean breathing rate for the INTER test and the Dynamic Yo-Yo test resulted in a very strong correlations (r=0.8) which was statistically significant (p=0.000). Participants spend on average 72% of match-play at >85% HRpeak compared to the 52% and 78% spent at >85% HRpeak during the INTER test and the Dynamic Yo-Yo test respectively. The INTER test produced a greater number of statistically significant correlations with the combined matches compared to the Dynamic Yo-Yo test. When identifying the differences between the variables measured in the INTER test and the Dynamic Yo-Yo test, it was identified that there were many significant differences. Conclusions: Both the Dynamic Yo-Yo and the INTER test can be used by hockey coaches. However, the researcher would recommend the utilisation of the INTER test, because it displayed stronger, more significant correlations to match-play. The set-up of the INTER test is also more convenient as it can be conducted on the astro turf. While, both tests did have some correlations to match-play, additional tests would need to be included in a testing battery to provide coaches with complete profiles of the players in order to assist in team selections. , Thesis (MA) -- Faculty of Health Sciences, 2022

Participants spend on average 72% of match-play at >85% HRpeak compared to the 52% and 78% spent at >85% HRpeak during the INTER test and the Dynamic Yo-Yo test respectively. The INTER test produced a greater number of statistically significant correlations with the combined matches compared to the Dynamic Yo-Yo test. When identifying the differences between the variables measured in the INTER test and the Dynamic Yo-Yo test, it was identified that there were many significant differences. Conclusions: Both the Dynamic Yo-Yo and the INTER test can be used by hockey coaches. However, the researcher would recommend the utilisation of the INTER test, because it displayed stronger, more significant correlations to match-play. The set-up of the INTER test is also more convenient as it can be conducted on the astro turf. While, both tests did have some correlations to match-play, additional tests would need to be included in a testing battery to provide coaches with complete profiles of the players in order to assist in team selections. , Thesis (MA) -- Faculty of Health Sciences, 2022

- Description: This study explores the nature and scope of food insecurity among postgraduate students at Nelson Mandela University, South Africa. The study employed a mixed method approach to access postgraduate students and university officials to investigate the prevalence of food insecurity. The approach also assesses the demographic factors; academic and mental implications along with the coping mechanisms associated with the experiences of food insecurity in higher education South Africa. The study incorporates an adapted conceptual framework from Alaimo’s food insecurity socio-economic risk models (2005) to understand the higher education context. Alaimo’s model seeks to connect the household conditions and broader systematic socio-economic mechanisms that households adopt to secure food. This model was adapted and employed in understanding the data collected while using a mixed-method approach between June and August 2021. The study employed an online survey for only postgraduate students enrolled at Nelson Mandela University (NMU) during the time of the study. This was supplemented by semi-structured interviews with student affairs officials that are directly involved in the formulation of strategies used to alleviate food insecurity at NMU. With 78 postgraduate students responding to the online survey, the study seems to confirm some of the studies done in this field on the inadequacy of food banks and food gardens in addressing food challenges effectively on campus. Similarly, the study found that the experiences of food insecurity were prevalent amongst postgraduate students that identified as black, low-income, and making access of the campus clinic for food relief. The study concluded by recommending a collaborative and a multi-level systematic approach in alleviating food insecurity in higher education. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2022

- Description: This study explores the spiritual relationship of water and uluntu lwase (people of) Port St. Johns, Eastern Cape, South Africa. Particularly the people that reside or regularly visit Isinuka sacred springs. This is done through an analysis and observations of the ritual practises performed at Isinuka sacred springs in Port St. Johns. This spring has provided sacred water used for healing, cleansing, and drinking for decades. Therefore, in this research we use the sacred water as an analysis point to understand the genesis of the ecological relationship of indigenous people and the environment. More so, this study uses the sacred water of the spring as an access point into indigenous knowledge systems (IKS) that have been passed on and maintained throughout history by the African elders. µRitual archives¶ have proved to carry indigenous knowledge systems on the history and philosophies of native regions and countries. Therefore, folktales, rituals, idioms and songs are didactic, and were intended to teach and sustain Isintu sakwa Xhosa (customs). This study uses observations ritual practises and face to face interviews to uncover the importance of nature and indigenous understanding of the environment from AmaXhosa residing in this area. The study was conducted in Port St. Johns in the rural parts of the Eastern Cape. Port St. Johns is a region of residing amaMpondo, which is an isiXhosa dialect. Therefore, amaMpondo and AmaXhosa are used in the study interchangeably. The researcher spent weeks visiting the spring daily and conducting qualitative semi-structured interviews. Observations and partaking in rituals were also used as a methodological approach to understand and capture the full experience of the sacred spring. The study uses the concept of as a medium to examine the relationship of water to spiritual ritual practises. The study literature shows a huge disjuncture between the literature written about the spring and the sociological meaning of the spring to the people that visit the spring. The results showed that the healing properties in the spring were caused by elements such as sulphur(s) and not the only the ritual practises that are performed at the spring. The study shows that, it is in the ritual practises that native Africans show their knowledge of the historical cosmological relationship between people and the environment. This is indicated in their use of sacred sites such as caves, rivers and ocean water to communicate with their ancestors. This study hopes to contribute towards a richer understanding of spirituality, ritual and archival work, for a holistic policymaking when dealing with water policies through an inclusive African indigenous perspective. , Thesis (MA) -- Faculty of Humanities, School of Sociology and anthropology, 2022

- Description: Strategy implementation faces many challenges within the public sector of South Africa. Previous research suggests that factors such as strategy formulation, strategy control and follow-up, leadership and suitability motivation, management and employees and corporate governance leading the change influence strategy implementation to various degrees. These factors are said to influence strategy implementation positively. The aim of the study was to investigate the relationships between the above-mentioned independent variables against a dependent variable, namely, strategy implementation. In the literature review, various topics such as leadership, strategy formulation and motivation, were discussed. Descriptive statistics were derived with regard to the prevailing levels of the various independent variables within the Coega Development Corporation. The sample of this study consisted of 50 employees at different levels within the Coega Development Corporation in the Eastern Cape. The regression analysis of this study showed that all factors were statically significant except leadership and suitability motivation, management, and employees. This factor was found to be statistically insignificant as the p value was greater than 0.05 (p= 0.169289). Furthermore, the statistical data analysis indicated that strategy implementation within the Coega Development Corporations is influenced positively by factors such as strategy formulation, strategy control and follow-up and corporate governance leading the change. The managerial implications of the empirical results were discussed in the study. , Thesis (MA) -- Faculty of Business and Economic science, 2022

- Description: South Africa is the third largest economy on the African continent. Moreover, it is the most technological, industrialised and diversified economy in Africa. Its economy consists of various sectors, such as mineral resources, financial, services and manufacturing sectors, as well as other sectors. It is imperative that these sectors are and remain competitive as they impact directly on the economy of the country and the continent which has an impact on all citizens in the country. An important resource is that of human resources in these sectors. Employees in these sectors form part of various departments of the specific organisation they are employed by, with their own duties and responsibilities. All departments in an organisation have an integral part to play to ensure that an organisation is indeed successful and sustainable. The human resources department plays an integral role and provides service to the various departments and thus impacts the success of the organisation. The HR practitioners who work within the HR department need to be engaged to fulfil their duties effectively. The purpose and primary objective of this study was to identify factors that influence the engagement of HR practitioners. To achieve this, a quantitative research approach was followed. HR practitioners were sent an electronic survey questionnaire to gauge their levels against communication, leadership support, meaningful work and rewards and recognition. The data from the empirical study was analysed by using descriptive and inferential statistics. The study was also tested for validity and reliability. The study concluded with recommendations on how HR practitioners can be further engaged. , Thesis (MA) -- Faculty of Business and Economic science, 2022

- Description: the change in South Africa, post the apartheid regime when the labour laws were amended and the law of equality instilled, women are still under-represented in the construction industry of South Africa, particularly in senior management positions. The purpose of this study was to investigate the factors affecting the career growth of female engineers in the construction industry of South Africa. The study was guided by the following objectives: to investigate if education influences women’s career advancement in the construction industry of South Africa, to establish the extent to which gender negatively impacts women’s career advancement in the construction industry of South Africa, to determine the rate at which women are promoted to senior leadership positions in the construction industry of South Africa, and to establish the extent to which the construction industry of South Africa goes to retain women within the industry. According to the study's findings, women in South Africa's construction industry have prospered from their qualifications (education). They stated that their education influenced their career path. The respondents believe that their gender does not prevent them from pursuing management positions. Women's retention in the construction industry is gradually improving. It was suggested that women be allowed more liberty in leadership roles so that they can perform to their full potential. Flexible working hours must be made available to women in order for them to be able to manage job and family obligations. This is not to say that women aren't capable; rather, it's a means of inspiring and recognising that, just as they are in the office, they are also leaders at home. , Thesis (MA) -- Faculty of business and economic sciences, 2022

- Description: Spaza shops, originating in South Africa during the 1970’s, often operate in townships, selling products and services to customers who live mostly within walking distance of the shop. Almost five decades later, and spaza shops abound across most townships in South Africa. These businesses not only provide grocery items and services to customers in the township community but are a means for people to earn a livelihood for themselves and also contribute economically through creating employment opportunities in the informal sector. Research about spaza shops shows that there is a growing customer interest in purchasing products and services from spaza shops, and that if spaza shops are to continue growing, they need to be more competitive. Research by renowned authors in the field of experience marketing, Pine and Gilmore (2013) puts forward that experiences are the new relevant economic offering, and an essential value creating platform for businesses to be more competitive. However, before customer experience can be enhanced in spaza shops, it is important to first identify the factors that influence customer experience in a spaza shop context. Considering the latter, the primary objective of this study was to measure factors that influence customer experience in spaza shops. A descriptive research design was selected for this study, followed by a positivistic research paradigm and quantitative research methodology. Secondary data was collected through articles, journals, books and from newspapers. Primary data was collected using a survey in the form of a self-administered questionnaire. The target population for this study was customers who are older than 18 years, who had bought grocery items (products and services) in spaza shops located in Nelson Mandela Bay townships specifically in Walmer Township, KwaZakhele, Zwide, Motherwell, KwaMagxaki and New Brighton. A non-probability sampling method and convenience sampling technique were used to distribute a total of 200 selfadministered questionnaires. Once the data collection phase was completed, the data from the questionnaires was recorded, coded, and cleaned on a single excel spreadsheet. After the latter was done, a total of 185 questionnaires were deemed useable and considered for data analysis, which was conducted with the aid of IBM SPSS Statistics version 27 (computer software). , Thesis (MCom) -- Faculty of Business and Economic Sciences, School of Management Sciences, 2022

- Description: Given the historically disadvantaged position of women and their heavy reliance on climate-sensitive activities in many societies, the vagaries of the climate threaten the agrarian livelihoods of women in Chivi district. This study focuses on the impacts of climate change on women working in agriculture in one ward of Chivi district and on the feminization of agriculture during the period from 2000 to 2019. It explores how the roles of women have changed in agricultural production and in relation to household food security. It assesses women’s involvement in decision-making in agriculture as well as in household food security, and analyses the socio-economic impacts of climate change on women subsistence farmers, exploring the adaptation strategies that rural women working in agriculture implement in response to climate-risk events and threats. The study was influenced by ecofeminist theories and the Sustainable Livelihood Framework. Comparative analysis of household types was done after data gathering using participatory rural appraisal tools with women from three villages. Interviews were conducted with key informants from government departments and development institutions. The results show that climate-risk events and threats have resulted in feminization of agricultural labour as men branch out into wage labour, but that changing power relations in the form of decision-making in agriculture and issues related to household food security vary with the type of the household. Worsening climatic conditions have made it difficult for women to ensure household food security and to generate income through agrarian livelihoods. However, women have implemented adaptation strategies including conservation agriculture to mitigate crop failure, and to improve agricultural output and household daily consumption, and thus survive peak hunger periods. The study contributes to our understanding of the resilience of women in the Global South to climate-risk events and threats and contributes to our understanding of participatory rural appraisal tools in addition to conventional data collection tools. The study recommends that development institutions promote gender equality and that development institutions construct dams, rehabilitate collapsed irrigation schemes and accelerate the implementation of novel climate smart technologies in arid regions. , Thesis (PhD) -- Faculty of Business and Economic science, 2022

The study recommends that development institutions promote gender equality and that development institutions construct dams, rehabilitate collapsed irrigation schemes and accelerate the implementation of novel climate smart technologies in arid regions. , Thesis (PhD) -- Faculty of Business and Economic science, 2022

- Description: As top predators, seabirds occupy the upper trophic level of marine ecosystems. They are consequently important for the maintenance of ecosystem structure and function, while also possessing characteristics which are useful for identifying climate-driven changes in oceanography at all trophic levels. This important faunal group is one of the most threatened, with climate change and fisheries bycatch mortality being the primary drivers of population declines. Understanding these threats is important for the management of threatened seabird populations. One impact of climate change and variability in climate occurs through changes in prey availability. As central place foragers, breeding seabirds have trip duration constraints due to the obligation of nest duties. This makes them particularly vulnerable to changes in prey availability within their foraging ranges. The ability to adjust foraging behaviour during environmental conditions which alter prey availability is an important attribute which can contribute to breeding success. Thus, investigating for this foraging behavioural plasticity during different breeding stages provides insights into how a species is likely to be impacted by climate change. The sooty albatross population on Marion Island was studied and displayed a degree of foraging behavioural plasticity during the five-year period of pronounced climatic variability studied. Incubating birds mainly foraged in the subtropical convergence zone (STCZ), the Sub Antarctic Front (SAF) and Subtropical Front (STF) which border it, and the region north of the STF. Brooding birds mainly used the SAF and Polar Frontal Zone (PFZ). Significantly different areas were used between years during both breeding stages. This population showed a lack of consistent habitat preferences which may offer resilience to progressive climatic variability and change. Interactions of sooty albatrosses, as well as white-chinned petrels for comparative purposes, with fisheries were also assessed. The two species were compared to shed light on possible explanations for differences in seabird-fishery interactions between the species. The impact of fisheries-related mortality (bycatch) is dependent on exposure to fishing activity and attraction to fishing boats encountered while foraging. Bycatch mortality has previously been proposed as the main cause of this sooty albatross population’s decline. Exposure and 6 attraction to fishing boats was found to be lower than that of white-chinned petrels which are bycatch prone. However, the current level of attraction exhibited by this sooty albatross population may expose a significant fraction of the population to bycatch risk due to its small population size. Additionally, all fishing boats were encountered north of the STF where non breeding individuals are now known to be distributed. Thus, the impact of fisheries on this population may mainly be mediated by more bycatch prone non-breeding individuals. Overall, the relative impact of fisheries bycatch mortality is suggested to be higher than that of climatic impacts on the sooty albatross population on Marion Island. However, this study did not incorporate dietary and demographic information which would reveal whether there are nutritional differences between years that may impact on breeding success. An integrated rather than independent assessment of foraging behavioural responses to climatic variability and fishing activity is recommended for improving our understanding of current and future conservation priorities. , Thesis (MSc) -- Faculty of Science, Zoology , 2021

- Description: The study analyses the role that hard and soft infrastructure plays in attracting FDI inflows in the SADC region. As proxy for soft infrastructure, Internet users and governance indicators were used. Panel data was used for the analysis, for sixteen SADC member states, covering the period 2000 to 2018. Data was analysed using the multiple linear regression technique, applying the Random Effects Model. The results show that for soft infrastructure, government effectiveness (positive) and rule of law (negative) plays a vital and significant role in attracting FDI inflows into the SADC region. For hard infrastructure, telephone density and gross capital formation have a positive relationship with FDI. Soft infrastructure was found to be of more significance in attracting FDI inflows compared to hard infrastructure. Other variables, such as population growth rate, market size and trade openness were also found to have a significant relationship with FDI inflows in the SADC region. The study concludes that, although soft infrastructure plays a more significant role the two forms of infrastructure play a complimentary role in the attraction of FDI. To improve FDI inflows in SADC, the study recommended that SADC member states must dwell more on improving soft infrastructure, but also working on hard infrastructure development and making policies that attract FDI in the region. SADC countries should consider consolidating their policies towards both soft and hard infrastructures to obtain some form of convergence on infrastructural levels within the region. , Thesis (MA) -- Faculty of Business and Economic science, 2022

- Description: Various pharmaceutical materials are known to take up moisture during both storage and manufacture. This phenomenon, termed hygroscopy, can result in unacceptable levels of moisture, potentially having deleterious effects on product quality, and consequently product efficacy and safety. Drug inefficacy specifically can result in life-threatening complications for the pregnant mother with uncontrolled blood pressure. Marketed as immediate release tablets, methyldopa is an antihypertensive drug commonly used in South Africa to treat hypertensive disorders of pregnancy. Despite being in use for over 50 years, the physicochemical challenges posed by methyldopa remain ever present. Methyldopa is not only significantly hygroscopic, but also prone to oxidative and hydrolytic degradation that can be accelerated by moisture. Poor compression behaviour, another limitation of methyldopa, leaves the formulation scientist with a constellation of formulation hurdles that must be faced, understood and overcome. This is a task that can be tackled using elements of the Quality by Design (QbD) approach. Using this approach, the impact of these phenomena on tablet quality can be better understood and controlled. This study was aimed at using this approach to develop a formulation of methyldopa 250 mg tablets. Direct compression, a simple and moisture-free process, was selected for the manufacture of methyldopa tablets. After careful review of literature and consultation with experts, excipients were selected for the candidate formulation and preliminary concentrations established for each. Similarly, settings for mixing and compression variables were established. Adopted from the QbD framework, the risk posed to tablet quality by these factors was qualitatively analysed using Preliminary Hazard Analysis (PHA) and quantitatively evaluated using Failure Modes and Effect Analysis (FMEA). Eight (8) factors determined to be high risk were further investigated in a preliminary experiment that followed a 12-batch Plackett Burman design. Data from this experiment was used to draw statistical relationships between the aforementioned factors and tablet quality attributes, thus shedding light on excipients and process parameters with practically significant impact on methyldopa tablet quality. Multivariate Analysis of Variance (MANOVA) of the response data reported SSG concentration, citric acid monohydrate xxvii concentration and mixing speed as key factors (p<0.05), demonstrating the need to control these factors for quality targets to be met. These three factors underpinned the 16-batch definitive experiment that followed, conceived using a Box Behnken design (BBD) including four batches prepared at the centerpoint values in the region of experimentation. The optimal methyldopa tablet formulation was achieved at the following settings: 1.0 % m/m magnesium stearate, 1.0 % m/m colloidal silica, 3.9 % m/m sodium starch glycolate, 1.7 % m/m citric acid monohydrate, mixing speed of 101 rpm, 6 minutes of pre-lubrication mixing, 2 minutes of lubrication and compression speed of 20 rpm. These settings were included in the design space and subsequent control strategy. It was learned that, within the design space, the risk to tablet quality and, by extension, the patient, was insignificant. This demonstrated that, using the QbD approach, challenges to pharmaceutical development can be effectively overcome. , Thesis (MA) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: African has relatively low levels of economic complexity as the continent is centred on the production and exporting of natural agricultural goods, non-renewable natural resources, minerals, and crude oil, additionally the agricultural sector continues to be the prevalent employer. The purpose of this study is to examine the relationship between governance, institutional quality, with economic complexity in Africa. Panel data for the period 1996 - 2019 is employed and the generalised method of moments (GMM) technique was selected due to the number of countries (36 countries) being more than the time periods (22 years). The Granger non-causality test of Juodis, Karavias, and Sarafidis (2021) is used to figure out the direction of causality between the variables used in the study. The GMM results indicate that governance and institutional quality have a positive effect on economic complexity. The Granger causality test suggests that there is one directional causality from governance to economic complexity and from institutional quality to economic complexity. It is recommended that African countries improve governance through electing selfless leaders whose goal is improve the lives of its individuals. With regards to institutions, Africa needs to adopt strategies that support institutional quality which in turn will promote economic complexity. Policy makers should also create an environment or policies that are conducing for domestic and foreign investments, which in turn would improve the continent’s economic complexity. , Thesis (MA) -- Faculty of Business and Economic science, 2022

- Description: In 1994 the new democratic government of South Africa introduced the Reconstruction and Development Programme (RDP) which was aimed at massive infrastructure expansion. Tackling the housing crisis has been encountered by growing demands for low carbon footprint, reduced use of non-renewable resources and as part of the green agenda. In line with the Sustainable Development Goals (SDGs), the South African government set a variety of objectives aimed at achieving an environmentally sustainable future for all. While South Africa has embraced green economy principles, tested integrated approaches are still to be seen in housing construction. This study sought to explore the greening of Ndlambe green village in the Port Alfred area in the Eastern Cape Province of South Africa. To achieve the study objectives, a qualitative research approach was used, employing the case study research strategy and primary data was collected by means of focus groups. Community members, engineers, environmentalists and town planners constituted the study sample. Secondary data sources were also used in this study, along with field observation. The collected data was analysed using the thematic analysis technique. Findings from the study revealed that community members perceived Green village initiative as important and is required in South Africa given the challenges that are experienced such as energy consumption load shedding, water shortages. The economic value proposition of green building is measured through two different lenses, namely economic profit and social profit. The municipalities must take a leading role in by forming policies supporting environmentally friendly activities, with building being one crucial area. Recommendations from the study proposed that partnerships involving communities, private companies, the government and other various interest groups are imperative in order to accelerating the green building agenda. The government must be challenges to develop sustainable funding solutions for a green economy. Lastly, increased awareness about green building among the society may also drive better acceptability and ultimately, a strong social reputation. , Thesis (PhD) -- Faculty of Engineering, the Built Environment, and Technology, 2022

- Description: Globally, the construction industry is infamous for a high level of fatalities. Construction sites are a very important place, as a considerable number of workers are involved in the construction process and activities, and H&S is critical to reduce hazards and the risk of being injured at work. The aim of the study was to evolve a framework of interventions to mitigate hazards, diseases, illnesses, injuries, fatalities, stress, and absenteeism in the construction industry. The objectives were to determine: why workers become ill due to construction and the implications; the causes of stress among construction workers, and worker absenteeism; what injuries workers experience, and the causes of fatalities, and if the current control measures are sufficient or whether more can be done. The research process commenced with a literature review relative to hazards and risks in the construction industry. A quantitative study was conducted among civil engineers, site supervisors, and construction H&S officers (CHSOs) in the construction industry using a questionnaire. The salient findings of the study suggest that the existing H&S legal and regulatory framework is barely effective. Although building contractors are aware of the most common H&S hazards and risks in construction, compliance is irregular. The study concluded that the identification of H&S hazards and risks is critical to mitigate fatalities, injuries, and illness. H&S education and training, and hazard identification and risk assessment (HIRA) should be improved and intensified, and a comprehensive risk mitigation plan should be developed and implemented on projects. , Thesis (MA) -- Faculty of Engineering, the Built Environment, and Technology, 2022
