- Description: The South African city faces an ongoing struggle with adequate social and spatial justice. Citizens have become separated and cultures have been divided owing to the historical formation of the city and the post legislative laws. Because of the growth of cities, certain resources are difficult to access and people need to trav el vast distances and cross dangerous barriers in order to access these resources. This thesis involves the research of social and spatial justice within the South Afri can city, which has resulted in a poor quality of life and a lack of resources. More specifically this thesis aimed at creating an environment that will aid in a better quality of life through spatial and social equity by creating an active and positive space to access certain resources. The particular focus area is the rural community of Pellsrus in Jeffreys Bay. The context has been analysed to enable a sound understanding of the formation of the town, the behaviour of the town and its people, the urban conditions and the spatial structures. Research lead to a site being selected that would form an transition space connecting separated communities and resources. The design is aimed at creating a space for people to gather, gain access to the needed resourc es and act as a linkage or transition zone between certain areas of the town. The objective was to enrich the current movement systems and enhance the existing resources, ultimately resulting in the design of a trade-resource centre in Pellsrus. The architectural design is formulated as a mean of locality and community. A qualitative methodology has been implemented which incorporates various research methods such as surveys, literature reviews, primary and secondary data collection, site sketches, topographic mapping and drone footage. , Thesis (MSc) -- Faculty of Engineering, the Built Environment and Technology, School of Architecture, 2022

- Description: The identity of youth is an important developmental pro - cess in young people’s lives. Youth Centres in South Africa mainly focus on reproductive health services and as a result thereof, are experiencing low visitor num - bers and failing to captivate the youth whom they aim to serve. The very nature in which this takes place today, opens the door for an architectural intervention that has the potential to facilitate and improve this process. This thesis aims to address the issues that today’s youth faces by looking at the metaphorical representa - tion of the ‘street’ as the current place where the youth of today spend their time testing and developing their identity. It aims to rethink the youth centre as a place that combines youth culture and architecture to create a space which provides adequate recreational opportu - nities, and through which youths can reconnect to their surroundings - giving them a much-needed sense of place and identity within the ever-changing city. The idea is ultimately to design a Youth Activity Centre for the Parkside neighbourhood in East London - a de - sign which can express how youth identity can impact architecture in a way that can benefit the development of youth’s identity, and which can re-animate the nature of the ‘street’ through architecture. , Thesis (MArch) -- Faculty of Engineering, the Built Environment and Information Technology, School of Architecture, 2021

- Description: Small and medium enterprises (SMEs) internationally have a significant involvement in global economies, as they often are key drivers of economic growth through job creation, increasing production volumes, increased exports and imports. SMEs’ access to development finance and other financing products in the market remains one of the most significant constraints to the establishment, survival, growth, and productivity of SMEs. The South African Government has enacted policies to support SME development and enhance financial inclusion; however, the financing gap has proven to be persistent. Most SMEs cannot access various development and commercial credit funding due to a number of reasons, such as: the detailed complex financial documentation, own contribution and collateral required by finance institutions to grant loan finance; high cost involved in raising loan funding and high punitive interest rates due to the perceived high risk nature of the SMEs; and long time frames for the economic viability and business sustainability assessment processes for credit approval. In this study, a broad analysis of a viability based lending format of a development funding institution was conducted with the intention to develop a framework to assess its effectiveness to facilitate increased financial inclusion in the SMEs sector in KwaZulu-Natal. The study used the literature review to identify key factors that have an impact on economic viability and business sustainability/feasibility in terms of how these factors influence perceived financial inclusion of SMEs. The empirical section of the study tested SMEs’ perceptions and understanding of the concepts that influence the economic viability and business sustainability/feasibility of the SME sector. Strong evidence emerged from the empirical study that SMEs lack crucial resources such as own contribution to achieve an optimal equity structure in the business, lack of grant funding information available to support SMEs, lack of collateral required for funding security, lack of business support available to SMEs to compile comprehensive business plans and lack of own resources to manage various aspects of the business. Without appropriate coordination of the SMEs’ ecosystem, financial inclusion for SMEs will remain a challenge. , Thesis (MBA) -- Faculty of Business and Economic Sciences, NMU Business School, 2021

- Description: The financial exclusion of the poor from the formal financial sector has contributed to the never ending cycle of inequality and poverty in South Africa. It is however evident from the R50 billion (Nasasa, 2020) generated each year in the stokvel market, that those previously excluded have been able to create their own informal market with immense potential. The full potential of the stokvel market has however not been adequately explored which has resulted in members not fully utilising this informal sector to improve their standards of living and the formal sector not providing adequate product solutions to benefit members. Majority of stokvels are still focused on traditional rotationally disbursement mechanisms designed for short-term goals (Zondi, 2016) and regardless of the market that has growth to be worth R50 billion, members are yet utilise funds accumulated on instruments and mechanisms to improve standards of livings for themselves, families and general communities. The formal sector provides stokvel savings products that offer stokvels with simple savings mechanism often generating little interests which may not necessarily provide the full potential benefit to the members. This was also shown in a study by African Response (2019) indicating that 40% of stokvels had their money invested in low to no interest accounts. Stokvels have also evolved and are now used for far more than just a simple savings mechanism, with some stokvels focusing on continuous rotationally mechanisms, while others focus on fixed periods. Stokvels can exist for different reasons including for groceries, burial, school fees and longer term purposes such as building houses or buying cars or a combination of these. Solutions available ought to therefore take into consideration the key needs of stokvels while considering short term and medium to long term solutions which current simple savings solutions offered by the formal sector may not completely offer. In keeping up with the market, banks may try to enhance their products but Moliea (2017) concluded that banks were being flexible on things that members did not require. Against the stated research problem, the primary objective of this research is to investigate how the traditional mechanisms of stokvels can be amended and improved to ensure maximum benefits/returns for its members; which benefits are not only long-term in nature, but also taking account of the short-term needs and realities of poor communities within the context of the South African economy. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business Administration, 2021

- Description: This thesis presents the development of a regional ionospheric storm-time model which forms the foundation of an index to provide a quick view of the ionospheric storm effects over South African mid-latitude region. The model is based on the foF2 measurements from four South African ionosonde stations. The data coverage for the model development over Grahamstown (33.3◦S, 26.5◦E), Hermanus (34.42◦S, 19.22◦E), Louisvale (28.50◦S, 21.20◦E), and Madimbo (22.39◦S, 30.88◦E) is 1996-2016, 2009-2016, 2000-2016, and 2000-2016 respectively. Data from the Global Positioning System (GPS) and radio occultation (RO) technique were used during validation. As the measure of either positive or negative storm effect, the variation of the critical frequency of the F2 layer (foF2) from the monthly median values (denoted as _foF2) is modeled. The modeling of _foF2 is based on only storm time data with the criteria of Dst 6 -50 nT and Kp > 4. The modeling methods used in the study were artificial neural network (ANN), linear regression (LR) and polynomial functions. The approach taken was to first test the modeling techniques on a single station before expanding the study to cover the regional aspect. The single station modeling was developed based on ionosonde data over Grahamstown. The inputs for the model which related to seasonal variation, diurnal variation, geomagnetic activity and solar activity were considered. For the geomagnetic activity, three indices namely; the symmetric disturbance in the horizontal component of the Earth’s magnetic field (SYM − H), the Auroral Electrojet (AE) index and local geomagnetic index A, were included as inputs. The performance of a single station model revealed that, of the three geomagnetic indices, SYM − H index has the largest contribution of 41% and 54% based on ANN and LR techniques respectively. The average correlation coefficients (R) for both ANN and LR models was 0.8, when validated during the selected storms falling within the period of model development. When validated using storms that fall outside the period of model development, the model gave R values of 0.6 and 0.5 for ANN and LR respectively. In addition, the GPS total electron content (TEC) derived measurements were used to estimate foF2 data. This is because there are more GPS receivers than ionosonde locations and the utilisation of this data increases the spatial coverage of the regional model. The estimation of foF2 from GPS TEC was done at GPS-ionosonde co-locations using polynomial functions. The average R values of 0.69 and 0.65 were obtained between actual and derived _foF2 over the co-locations and other GPS stations respectively. Validation of GPS TEC derived foF2 with RO data over regions out of ionospheric pierce points coverage with respect to ionosonde locations gave R greater than 0.9 for the selected storm period of 4-8 August 2011. The regional storm-time model was then developed based on the ANN technique using the four South African ionosonde stations. The maximum and minimum R values of 0.6 and 0.5 were obtained over ionosonde and GPS locations respectively. This model forms the basis towards the regional ionospheric storm-time index. , Thesis (PhD) -- Faculty of Science, Physics and Electronics, 2021

- Description: The “South African education system is grossly inefficient, severely underperforming and egregiously unfair” (Spaull, 2013, p.3). In particular, grave concerns with learner performance in mathematics in South Africa are well documented (e.g., Taylor, 2008; Spaull, 2013; Venkat & Spaull, 2015). There are various explanations for the poor state of learner performance in mathematics in South Africa. Two of the explanations that relate closely to my research interest are teachers’ insufficient mathematics content and pedagogical knowledge, and inappropriate professional development. This study aims to ascertain how a collaborative intervention can develop teachers’ mathematics and pedagogical content knowledge as they focus on developing learners’ foundational number sense. Cultural Historical Activity Theory, together with Mathematics Knowledge for Teaching (Ball et al., 2008) and the Knowledge Quartet (Rowlands & Turner, 2007) frameworks, provide the explanatory and analytic tools for the research. The research is a qualitative case study underpinned by an interpretivist orientation. The study was conducted at a township public primary school in the Northern Cape. Three Grade One teachers participated in the research. Data was collected through interviews, classroom observations, and videos of collaborative lesson planning and reflection sessions. A key finding emerging from this research is that the teachers had the necessary mathematics content knowledge to teach Grade One mathematics. Despite this and in contrast to it, they lacked adequate pedagogical content knowledge required to develop learners’ number sense. To develop their pedagogical content knowledge, they required the intervention of a ‘more knowledgable other’ (Vygotsky, 2008). Several contradictions and tensions emerged from the research. For example, the teachers expressed that the opportunity to work collaboratively was beneficial, but it was evident that they were familiar with and accomplished in planning and working together. The contradictions emerging from this research provide an opportunity and basis for expansive learning for future collaborative teacher endeavours. , Thesis (MEd) -- Faculty of Education, Education, 2021

- Description: South African labour law is founded on the fundamental constitutional right of fair “labour practices”. This fundamental right is afforded to both the employer and workers. This means that in the employment relationship, there are two competing rights involved which necessitate the need to strike a balance when each party’s rights are exercised. Therefore, this right is not absolute, and it is subject to limitations as per the provisions of section 36 of the Constitution. The Labour Relations Act, amongst other labour law resources considered in this research, give effect to those competing rights and seek to strike the necessary balance by establishing guidelines to protect the individual employee against unfair dismissals, amongst other things. It requires that the dismissal of an employee be fair. This requirement is met where two elements are fulfilled: (1) substantive fairness and (2) procedural fairness. The purpose of this study is to focus on “misconduct” as a valid reason for dismissal, as well as “group or team misconduct” which is included in the notion and ambit of “misconduct”. This type of misconduct involves a group or team who the employer has identified as having committed a misconduct, but the employer, due to different reasons explored in this research, is unable to identify the specific individual employees directly involved in the primary misconduct it wishes to prosecute. Therefore, the employer formulates a disciplinary charge of “group or team misconduct” to discipline the entire group or team. This group or team may form part of the entire workforce or a team within a department of the employer’s business. , Thesis (LLM) -- Faculty of Law, Mercantile Law, 2021

- Description: The arrival of China in Malawi has been characterised by a growing sense of uncertainty where academics and social commentators at large have expressed concern over the intentions of the super power in the country. There are fears that China would like to extend its influence to Malawi as part of a broader push, to have greater influence in global politics and economics. That push is in part exercised through the media. The thesis examined the perception of Malawian journalists on how news media reports on Chinese activities in Malawi. It used content analysis to understand how the mediascape had changed from 2001 – 2007 when China had not established diplomatic relations with Malawi, and January 2008 – 2020 when China had established diplomatic relations. The thesis examined these shifts in journalistic representations of China in Malawi and developed prompts and probes from which journalist interviews were conducted. From the content analysis, it appears there is a remarkable change in the way China has been covered from 2001 – 2020. From 2001 – 2007, Malawian media, especially The Daily Times, was very harsh on China, uncritically reproducing Western representations of China as an aggressive country with no respect for human rights and dignity. This changed after January 2008 when the media leaned towards tolerance and acknowledgement of Chinese activities. Through interviews, journalists have indicated that the Chinese government offers opportunities, such as scholarships, fellowships, and exchange visits to journalists, making it difficult for them to bite the finger that is feeding them. This ‘soft power’ is backed up by the repressive power of the Malawi government, which uses intimidation to force journalists to report in their favour, thereby helping create a positive picture for China in Malawi. Journalists report that the significant shifts in journalistic representations of China have been mirrored by changes in the conceptualisation of journalistic roles in Malawi’s mediascape. , Thesis (MA) -- Faculty of Humanities, Journalsim and Media Studies, 2021

- Description: The infrastructure and use of the Internet have developed rapidly in recent years, which propelled traditional human resources systems into a new electronic human resources (E-HRM) approach. This cannot, however, be regarded as a one-size-fits-all solution as employees across different generational cohorts are not all at the same comfort level with regard to operating such web-based applications. It is the researcher’s opinion that the latter may affect employee engagement as this appears to be the case within the researcher’s own organisation. Employee engagement is important in providing organisations with the competitive advantage required to operate in a highly competitive market. Employee engagement levels are far from ideal across many organisations, which require these organisations to identify solutions to raise overall engagement levels. With age rapidly becoming a more important diversity factor, it is imperative for managers to understand the effect of E-HRM on employee engagement across the generational cohorts to design the most beneficial HRM strategy for their organisation. The purpose of this study is to gain a better understanding on how generational cohorts are affected by the application of E-HRM programmes and to identify whether there are substantial variances between the engagement levels of the different generational cohorts in this context. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business Administration, 2021

- Description: Phase change materials (PCMs) have been incorporated into clothing and textiles to provide added value in terms of thermoregulation and thus added comfort to the wearer in extreme weather conditions and sporting activities. Since clothing is laundered many times during the service life of the textile, the effects of simulated domestic laundering on the physical and thermal properties of a non-woven textile which contains PCMs were investigated. The thermal properties, such as the thermal degradation, melting, evaporation and crystallisation were measured by the TGA and DSC analytical techniques. The physical properties, such as the microcapsule size distribution, and the microcapsule morphologies of the PCM microcapsules, were measured by the SEM and Raman analytical techniques. The main objectives of this study were to determine the effect of repeated laundering at different wash temperatures on the mass loss, enthalpy, and physical changes in PCM. Thermal degradation as determined by TGA thermograms was found to be higher at a wash temperature of 60°C relative to that of a wash temperature at 30°C, the mass loss being 4.6% more at 60°C than at 30°C. This was asserted to physical changes such as size and shape of the PCM microcapsules as evident in SEM images. The SEM images showed broken and collapsed PCM microcapsules in the web and around the fibre, indicating evaporation of the thermoregulating content of the PCM. It was found that the heat capacity of the sample washed at 60°C was much lower than that of the unwashed sample, the difference being approximately 50% in terms of the latent heat capacity as determined by DSC thermograms. This implies that the latent heat effectiveness of the PCM has decreased significantly. The physical properties of the PCM such as the intermolecular interaction, the intensity and width of peaks, polarisation, degree of crystallinity and the orientation changed as illustrated in the Raman analysis. , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2021

- Description: The growth and feed conversion ratio of farmed abalone Haliotis midae (L. 1758) fed a formulated diet varies in feeds with different protein sources. To better understand this, the effect that various combinations of dietary soybean meal (SBM), sunflower meal (SFM) and fishmeal (FM) had on the digestive efficiency of farmed H. midae when included in a formulated feed, were assessed. The aim of this study was to investigate the effect that plant-based proteins had on abalone digestion and gut-bacterial profile of cultured adult abalone when combined with fishmeal. This was done by analysing the chymotrypsin (protease) and cellulase (carbohydrase) digestive enzyme activities from whole-gut sections of farmed abalone that were fed one of four diets for 12 months: FM-only, SBM-only, fishmeal and soybean meal (FM-SBM), and fishmeal and sunflower meal (FM-SFM). There were significant interactions between the diets, sampling date, and sex of the abalone, which had an influence on the cellulase activities in the digestive tracts of the animals. Those fed the SBM diet had the highest cellulase activity by the end of the sampling period (ANOVA; df = 9; F = 2.9; P = 0.005). The significant interactions between diet and sampling date influenced the chymotrypsin activities of abalone. Animals fed the FM diet had the highest activity of chymotrypsin for most of the sampling period (ANOVA; df = 9; F = 2.5; P = 0.01). Therefore, diet did have an impact on the cellulase and chymotrypsin activities of abalone fed either combination diets (FM-SBM; FM-SFM) or single protein diets (FM; SBM). The presence of plant material such as cellulose fibres in the diets containing plant proteins may have influenced the cellulase activity levels of each treatment as it would have stimulated endogenous and exogenous cellulase production. However, treatments with the highest crude fibre content, SBM and FM-SFM, resulted in differing activities. The activity levels of chymotrypsin may have been impacted by the protein type, presence of protein inhibitors and temporal changes in utilisation. Abalone fed the FM diet exhibited the highest chymotrypsin activities on sampling day 182, which was in summer. Animals fed the treatment diets containing fishmeal also developed their reproductive tissues, and may explain the low chymotrypsin activities in abalone fed SBM-only. Additionally, the presence of allergenic compounds would have influenced enzyme activity, as they would have negatively affected the nutrient utilisation and absorptive capacity. Fluctuations in water temperature may have had an effect on enzyme activity, as activities were highest during summer, when seawater temperatures are most variable. A change to lowered water temperatures are known to trigger the growth of digestive epithelial tissue in abalone to allow for increased enzyme secretions and nutrient absorption (Schaeffer et al. 2013). The effect that plant protein inclusion in abalone diets had on the gut-microbiota was revealed by analysing the differences in gut-bacterial community profiles, through the use of metagenomic sequencing. The relative abundance of the phylum Verrucomicrobia, class Verrcomicrobiae and the genus Rubritalea were highest in the SBM diet. These bacterial groups were also influenced by the plant material from soybean meal, as hydrolysed cellulose is broken down by cellulases, and allowed for the proliferation of Rubritalea bacteria due to them using cellobiose as an energy source. The presence of Bacteroidetes was due to the phyla having bacterial species that can breakdown proteins and species that can break down carbohydrates. The animal protein present in the composition of the FM diet had a positive influence on proteolytic Bacteroidetes growth. The high levels of cellulose from the plant fibres in the soybean meal-only diet (SBM) promoted growth of saccharolytic Bacteroidetes. Tenericutes bacteria’s prominence was due to the higher plant fibres from the soybean meal as some Mycoplasma are known to degrade polysaccharides. Therefore, exposure to formulated feeds with high levels of these plant materials would allow for high proliferation. The thesis established that plant-derived dietary proteins in formulated feeds result in an effect on digestive enzyme activity and a difference in the community structure of gut bacteria in H. midae abalone. The results from the current research highlight the importance of studying abalone gut physiology when investigating the impacts of formulated feed composition, and can be used as an additional factor when determining the efficacy of a dietary component. Further research on the gut-bacterial groups and different digestive enzymes of H. midae abalone is encouraged, in order to create a holistic view on their response to dietary plant proteins inclusion in formulated feeds, thus reducing the need for fishmeal protein. , Thesis (MSc)-- Rhodes University, Faculty of Science, Department of Ichthyology and Fisheries Science, 2021

- Description: Over several decades past, developing countries have received increased amounts of Foreign Direct Investment (FDI). This form of investment has been welcomed because of the perceived benefits attached to it. FDI is seen as an important driver of economic development for many nations. For South Africa specifically, GDP growth rates have remained less than required, unemployment rates have reached staggering levels, poverty and inequality levels are increasing and the list goes on. Considering the perceived benefits of FDI, one may argue that FDI can play a crucial role in reducing the mentioned challenges facing the nation, however, only if directed to initiatives contributing to growth and employment. The 2015 Investment Policy Framework for Sustainable Development includes an action menu promoting investment in sectors relating to the achievement of the Sustainable Development Goals (SDGs). Therefore, this study is aimed at investigating the relationship between sector FDI and sector growth in addition to investigating the effect of sector FDI on sector employment over the period 2000Q1 to 2016Q4 for six of South Africa’s economic sectors. The reason for such a study is based on the premise that developing nations such as South Africa lack sound trade and industrial policies favorable to foreign investors. This then leads to the nation failing to attract higher volumes of FDI which could be used to address structural challenges facing the country. It is therefore important to identify sectors in which FDI has resulted in growth and employment so that when policies are considered, the right FDI is targeted. A comprehensive review of existing theoretical and empirical literature showed that FDI does result in economic growth for developed and developing countries, although FDI crowds out domestic investment in the short run. Literature on the effect of FDI on employment showed diverse effects. Some studies found FDI to increase employment overall, other studies found FDI to increase employment only during periods of restructuring and some studies found FDI to result in job losses. For South African sectors, the present study finds that the financial services sector receives the highest volume of South African FDI, followed by the mining and quarrying sector and the manufacturing, however, FDI in all six sectors under study is associated with increased growth and employment. This finding suggests that the financial services sector has received increased volumes of FDI as a result of financialization of the South African economy. It is this increased FDI in the financial services sector that is directed to income redistribution from the real sector to the finance sector. This study employed econometric techniques and methods of analysis to investigate the relationship between sector FDI and sector growth, and the effect of sector FDI on sector employment. Panel cointegration tests were conducted for all six sectors included in the study to establish if long run equilibrium relationships exist among integrated variables. The Johansen-Fisher panel cointegration test revealed that there is evidence of cointegration in four of the six sectors. Since cointegration was established, the study proceeded to perform the Dumitrescu-Hurlin panel causality analysis and estimate a Panel Vector Error Correction Model (VECM). Results from the causality analysis found a unidirectional causality relationship between FDI and GDP growth, while the panel VECM found FDI to have a significant effect on growth in all sectors. The Seemingly Unrelated Regression (SUR) model employed to investigate the effect of FDI on employment found FDI to have an insignificant effect on employment in all sectors included, although the signs of the coefficients suggest that FDI is associated with increased employment and rising wages is associated with increased productivity growth. Since this study finds that FDI is associated with increased GDP growth in all six sectors under study, policy makers should devise strategies to attract FDI in sectors such as the transportation, storage and communication sector and the electricity, gas and water sector as FDI in these sectors are associated with increased growth however, they receive very low levels of FDI. There are a number of reasons for this, therefore, government institutions and policy makers should investigate the reasons for these low levels of FDI inflows into these sectors so that they can devise further strategies to address these reasons and perhaps attract higher levels of FDI into these sectors. Spillover benefits play a major role in host nations participating in FDI therefore, prior to entering into bilateral treaty agreements, policy makers should ensure that foreign investors are compelled to create jobs, offer training and qualifications etc. through their investments so that some of the SDGs can be achieved. Additionally, this study finds a positive, statistically insignificant relationship between FDI and employment. FDI may not have a significant relationship on employment due to jobless growth and capital-intensive growth rather than labor-intensive growth. Such a situation calls for government intervention. Skills shortage is a rising problem in South Africa; therefore, investors choose to employ advanced technologies rather than people. Under such circumstances, governments are encouraged to invest resources into skills development so that human capital are not completely replaced by technology. , Thesis (MCom) -- Faculty of Commerce, Economics and Economic History, 2021

- Description: The study sought to investigate the effect of using English as a language of learning and teaching on learner academic performance in the senior phase of Mthatha District, Eastern Cape Province. This study employed a mixed-method approach. The researcher used both qualitative and quantitative methods to collect data. The study was conducted in 3 semi-rural senior secondary schools that were conveniently selected. The quantitative part employed Likert-type scale questionnaires that were administered to 10 Mathematics (Math), 10 Natural Sciences (NS) and 10 Social Sciences (SS) teachers making a total of 30 teachers and a total of 30 learners from grades 8 and 9. For the qualitative part, nine (9) teachers and eighteen (18) learners from the selected schools were interviewed. The 18 teachers in three schools were observed as they taught Grade 8 and 9 learners in their respective classes. Qualitative data were, thus, gathered through interviews and observations. Quantitative data was collected using Likert-type scale questionnaires and was analysed using descriptive statistics and Microsoft Excel. The voice recorded qualitative data from the participant’s responses were transcribed and analysed manually through coding, forming categories and themes that were used for data presentation. These are some of the findings: The majority of learners do not understand English, therefore, it was difficult for them to understand the teaching and learning of the selected subjects in Senior Phase (SP) using English as the language of learning and teaching (LoLT); Although the majority of learners reported that they usually use English as a LoLT and their home language when learning the selected subjects, they still struggled to ask and answer questions in English in a classroom and during examinations; Learners who experience difficulties in learning the selected subjects through the use of English as a LoLT in SP, were taught in their home language (isiXhosa) by their teachers; English and isiXhosa, in the form of code-switching, were used when teaching the selected subjects; Inadequate teacher training and preparation made it more difficult for the learners to perform well in the selected subjects. The study recommends that: The Department of Education should conduct enough workshops to help HOD’s and teachers who teach the selected subjects to keep abreast of new developments in these subjects. These should be integrated with appropriate teaching strategies and learning and teaching support materials. Keywords: English as the language of learning and teaching, teaching strategies, learning, teaching support materials. , Thesis (D.Ed) -- Faculty of Education Sciences, 2021

- Description: The study sought to investigate the effect of water scarcity and coping practices of small-scale farmers in Marhewini and Megacom. The aim of the research was to assess how small-scale farmers are affected by water scarcity and the coping strategies used to mitigate the effects of water scarcity. The study is located within the interpretive paradigm, where realities are viewed and develops subjective meanings. Qualitative research methodology was adopted for the study as it investigates the subjective opinions of the respondents about the effects of water scarcity and their coping practices. The respondents offered their own opinions about their realities of the effects of water scarcity and coping practices. Both Marhewini and Megacom communities’ experiences water scarcity and they all have developed coping practices. The researcher used semi-structured interviews with small-scale farmers in Marhewini and Megacom as a tool to collect data. The findings from the study shows that Marhewini and Megacom locations have different garden sizes, that is Marhewini has larger gardens. It was found out that both areas (Marhewini and Megacom) experience challenges such as lack of fence and livestock that destroys crops. It was also found out that the effects of water scarcity included loss of interest in farming and delays in crop growth. There were various coping strategies that were used by small-scale farmers such as the idea of creating a water pump system and watering the garden before the crops are planted. It was indicated that most of the respondents did not have knowledge of sustainable development. Water scarcity is a problem facing both communities (Marhewini and Megacom) and the small-scale farmers have developed means to cope with the problem. Based on the findings, valuable recommendations were offered. These includes the farmers forming an association where they can share experience and knowledge. Also, the community could continue working together to ensure the idea of a water system is implemented and businesses (water suppliers) could work with the community to find an arrangement of providing affordable water. The department of water and sanitation could fund the idea of a water system. , Thesis (MA) -- Faculty of Business and Economic Sciences, Development Studies, 2021

- Description: Youth in conflict with the law is seemingly becoming a significant problem in South Africa, especially in the Eastern Cape where youth engage in risk-taking activities, such as anti-social behaviour and criminal acts. This study builds on factors contributing to youth delinquency such as negative behaviours of parents, dysfunctional families, high crime rate in communities, poor self-concept, low literacy level, poor socio-economic status and no sense of belonging. Against this backdrop there are programmes put in place as a form of rehabilitation for the youth in an effort to eliminate from amongst them, recidivism that conflicts with the law. However, little importance has been given to the challenges faced when implementing such programmes, such as illiteracy, rebellion, deviance and lack of resilience among youth. This context informed the study’s aim to explore the effectiveness of the rehabilitation programmes at the Bhisho Child and Youth Care Centre. To achieve this aim, the study employed the qualitative research approach to explore the rehabilitation programmes. Data was collected through 20 semi-structured interviews with purposively sampled participants (children/youth and personnel from the centre) ranging from those who perpetrated the heavier crimes to those who perpetrated the least crimes. Collected data was analysed through thematic analysis whereby tape recordings were transcribed, sorted and interpreted under themes that show common cause or commonalities among the research participants. The main findings show that the programmes offered to the youth are effective and play an important role in curbing their criminal behaviour. The acts of the study recommend that the personnel at the Bhisho Child and Youth Care Centre be equipped with more developmental services which can enable them to produce more effectiveness to the programmes offered by the centre. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2021

- Description: Geomorphological weathering processes and their relationship with temperature fluctuations are frequently researched. These research efforts are mostly restricted to surface conditions where soils, loose-lying rocks or rock outcrops are assessed. However, there is a shortcoming in the understanding of the thermal properties in a rock mass, particularly in the upper metres below the surface, as this has not been investigated or researched in any great detail. The research reported here is unique in this regard as it exploited the use of rotary core boreholes in tillite bedrock in the Karoo (Western Cape, South Africa) which were drilled as part of an invasive materials investigation for a proposed new hard rock quarry to supply road stone. Temperature data were captured on a bedrock ridge hosting tillite outcrop with a strong east to west orientation. The site work was done in two separate phases. The initial phase of research saw data being captured for one year on two aspects (i.e. north and south) at a depth of 0.3 m. This was followed by the second (more detailed) phase, where three aspects were assessed (i.e. north, south and a flat crest), but at depths of 0.3 m, 2.0 m and 6.0 m, totalling nine data acquisition points. The second investigation phase gathered data for seven months. Supplementary weather data were also captured for the site. Subsequent data analyses revealed that there is much to learn about the thermal behaviour of bedrock in the upper metres below the surface, and that the temperature properties or thermal regimes are not as simple as often assumed. Temperature differences related to aspect are not only surficial, but are transmitted to underlying bedrock, and notable temperature differences were measurable to a depth of at least 6.0 m. Seasonal temperature fluctuations also have a pronounced effect on the rock mass temperatures and it was proven that deeper parts of the bedrock accumulate and dissipate heat at different (i.e. retarded) rates compared with shallower parts of the rock mass, creating suitable thermal conditions to induce thermal fatigue. Thermal properties were also proven to be non-linear. During analyses, the concept of temperature inversions was proven, whereby one part of the bedrock becomes hotter or cooler relative to another/adjacent part of the bedrock, compared with its earlier temperature state. It was argued that these temperature inversions may exacerbate thermal fatigue. This research proved that aspect (i.e. directional heating) and depth need to be considered when analysing thermal regimes in a rock mass, as these have a distinct influence. The effects which manifest themselves create suitable conditions for thermal fatigue, not only near the surface but also at depth in the bedrock. Lastly, the effects of meteorological conditions on shallow bedrock temperatures were assessed. Preliminary findings suggest that boundary conditions and meteorological processes may indeed affect shallow bedrock temperatures, but only under certain circumstances and not to the same extent as reported in the literature for conditions researched at the surface. Wind temperature relative to the rock temperature, as well as a combination of wind and rain were found to be the most significant factors. , Thesis (PhD) -- Faculty of Science, Geography, 2021

- Description: This study investigated the effects of case study teaching on learners’ critical thinking and language literacy skills in Physical Sciences classrooms at secondary school level and whether it could be integrated into the secondary school Physical Sciences lessons without hampering the teaching program. This study is a step in the right direction as it pragmatically attempts to find a constructivism-driven pedagogical strategy that would optimise the attainment of the learning goals of Physical Sciences learners in their various academic settings. To accomplish the research aim, a mixed methods design, in which a non-equivalent (pre-test and post-tests) control-group quasi-experimental design was adopted for quantitative data collection and analysis, and an exploratory case study was adopted for qualitative data collection and analysis. The intervention in the experimental group was case study teaching, whereas in the control group it was the traditional lecture method of teaching science. The topic from the syllabus on which case study teaching was tested was Electricity and Magnetism. The population of the study was all Grade 10 learners studying Physical Sciences in the secondary schools of Sekhukhune East District. The sample consisted of 122 learners from four schools (70 learners from two rural (29 for experimental group and 41 for control group) and 52 from two urban schools (30 experimental group and 22 control group)). Two schools were treated as the experimental groups and the other two as control groups. A multistep sampling process was implemented in selecting the participating schools. Quantitative data was collected using a reading comprehension test, Critical Thinking in Electricity and Magnetism (CTEM) test and a summary writing task that was marked using a Holistic Critical Thinking Scoring Rubric (HCTSR) that was developed by Facione and Facione (1994) and analysed through both descriptive (means) and inferential (two-tailed t-test, Mann Whitney U test and effect size) statistics computed through PSPP statistical pack. Qualitative data was collected through classroom observation (participant observer) in which field notes were kept and face-to-face interviews were conducted, tape recorded and transcribed for analysis. Qualitative data was analysed thematically. , Thesis (PHD) -- Faculty of Education, 2021

- Description: The study examines the effects of Foreign Direct Investment (FDI) on economic growth and human capital in VISTA countries using time series and panel data analysis for the period 1990 to 2017. The Autoregressive Distributed Lag (ARDL) bound approach was applied in this study to examine the long-term relationships. The findings posited that there is a long-run relationship between economic growth, FDI, trade openness, capital formation, primary school enrolment, inflation over the period 1990 to 2017. The investigation of the long run and short run estimates results between FDI and economic growth indicated that FDI exhibited a positive effect on economic growth in Indonesia, while in Vietnam, South Africa, Turkey, and Argentina a negative relationship was established. Moreover, the findings of the panel data analysis showed that VISTA countries have been actively promoting policies and strategies that attract FDI to enhance economic growth. The study further incorporated the human capital results which indicated that FDI has a positive long-run relationship on human capital except for South Africa and Turkey. In the long run the results suggest that FDI has a negative effect on human capital only in Vietnam and Indonesia. Whereas, in the short run the results suggest that FDI has a negative effect on human capital only in Vietnam. The findings of the panel regression model carried out demonstrated that FDI exerts a positive and significant effect on human capital. It is evident that VISTA countries have made efforts to reform over the years, however, the spill over benefits of FDI are different from one country to another. Based on the empirical results acquired, even though it is advised that policy makers should intensify policies aimed at attracting FDI, policy makers must also give attention to other growth-enhancing factors such as human capital. , Thesis (MCom) -- Faculty of Business and Economic Sciences, Economics, 2021
