- Description: Customer Experience (CX) is the measurement of interaction between a customer and an organisation over a long time. Customer Experience is a strategic marketing effort that aims to improve the customer journey and touchpoints with the organisations’ product and services. It involves the complete customer journey – starting with the search process, purchase and after-sale processes of the experience. Google Trends identified that online users from all over the world search the key words “Customer Experience” more, often than not. This study considered a reliable measure for Customer Experience. This study endeavours to explore Customer Experience in the grocery retail sector in South Africa to put customer needs at the centre of their business. Extensive research on Customer Experience exist, however Customer Experience in the grocery retail sector in South Africa has not been measured using Professor Phillip Klaus’s new scale in CX. A broad literature review was conducted and Factors influencing Customer Experience in the grocery retail sector were identified and explored. The academic literature selected for the study is founded in the academic theories of Experienced Utility and Service-Dominant (S-D) Logic. The literature formed the foundation for the conceptual model that included the proposed Brand Experience (BE), Service Experience (SE) and Post-purchase / Consumption Experience (PE) independent factors. This treatise formed part of a bigger study of Customer Experience undertaken, using a questionnaire distributed via email, which 858 respondents completed. The study was quantitative. Data analysis included the use of descriptive and inferential statistics, Exploratory Factor Analysis, Reliability and Validity of Measurement, One-Sample T-Tests and the measurement of relationship between the factors. There is a need for companies to explore and understand CX in order to differentiate themselves strategically and to improve the bottom line. This study contributes to the body of knowledge by using academic literature and theories to explore Customer Experience in the grocery retail sector in South Africa. BE involves the customers’ perception of the brand and influence the customer’s experience. Customers look for clues to help inform their SE and expect companies to know their product and basic service promise. The findings of the study identified that BE and SE had a positive and significant influence on each other. Customers will show signs of commitment to an organisation during a positive PE. Similarly, the findings concluded that PE and CX had a statistical and practical significant positive correlation. PE was highlighted as a key determinant of CX. A positive CX will lead to a repeat purchases. Marketing managers need to take into account these factors when formulating CX strategies to influence the bottom line of the organisation. This study concludes with managerial recommendations that the grocery retail sector can implement to influence CX. Some of the recommendations include the appointment of a professional to manage all social media content; training and development opportunities for employees to enhance customer and shopping experience; and the use of customer data from loyalty programmes to promote personalised offers. In summary, a continuous review of CX with the emphasis on PE is recommended, to understand the changing needs of customers in the grocery retail sector. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business Administration, 2021

- Description: This study examines the influence of talent management strategies on employee retention with employee engagement as a mediating variable. This study was conducted at Aspen Pharmacare Port Elizabeth site, South Africa. The population in this study is approximately 1500 employees from Aspen Pharmacare Port Elizabeth. The sampling method uses census techniques so that the number of samples used is 49 employees. The research data was collected using an online questionnaire which is then analysed using a path analysis technique using SPSS software to examine the relationships among the variables, which are: employee value proposition, work motivation and employee performance. The results show that there is a positive relationship between all talent management strategies and retention. Leadership has a largely significant correlation with retention, however, it is indicated that engagement is a mediating variable. Employees with technical expertise value the impact that leadership has in their roles at the organisation. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business Administration, 2021

- Description: Learners’ low literacy achievements with regard to reading and writing in early schooling in South Africa remain a concern, particularly in the Foundation Phase. With regard to reading, amongst other things, Foundation Phase learners have been found to be “barking” at the text. That is an indication that they are struggling with achieving and grasping the main goal and purpose of reading, which is comprehension. In this dissertation, I explore the reading strategies teachers utilise in their grade 3 classrooms when teaching IsiXhosa and English. Participants for this study were grade 3 teachers from 2 different public schools in Idutywa District and grade 3 learners from 2 different public schools in Idutywa district. This qualitative study thus sought to investigate Grade 3 teachers’ strategies for developing learners’ reading comprehension skills in bilingual classrooms in two schools in the Idutywa Education District. Data was generated through semi-structured interviews. Amongst other issues, findings of the study revealed the following: participants reported valuing reading as an important skill that learners need to acquire academic success. Teachers demonstrated some understanding of how reading lessons are sequenced and paced. This study, thus, recommends that if learners are to acquire bilingual reading comprehension skills, both target languages should be valued and teachers be equipped on how to use these languages as resources in the classroom. , Thesis (MEd.) -- University of Fort Hare, 2021

- Description: Water is one of the scarce and constrained natural resource globally, and a necessity to every living creature, organism and the natural environment – it is the existence of life. Water, as an irreplaceable natural resource, plays a vital role in every country's development and prosperity, integrating socio-economic needs of both the present and future generation. Therefore, sustainable strategies and approaches or concepts are significant in ensuring that such a unique resource is preserved and conserved sustainably. Municipal environment or local government sphere creates a pivotal role in governing the use of water, through the provision of legislation, regulations and establishment of water conservation and water demand management strategies and plans. However, it has been established that there is a lack of integrated water resource management approach and planning in municipalities, creating concerns with regards to controlling the overutilisation of water and protection of water sources in general. The aim and goals of the study are to review Buffalo City Metropolitan Municipality's (BCMM) water conservation and water demand management (BCMM WC/WDM) development and implementation by, assessing the existing strategy related to water conservation and water demand management; constraints and opportunity identification; and provision of recommendations in improving the practices in the municipality. The study presents core theories and empirical studies relevant to the water conservation and water demand management, and also deals with theoretical framework found under the Natural Resource-Based View and its application to water conservation and water demand management concepts. A qualitative research design approach was used for the research, which is underpinned by a post-positivism paradigm. In terms of data collection, two methods were used in the study: (i) document study and secondary analysis; and (ii) semi-structured interviews with BCMM relevant officials. The study identified gaps and inconsistencies in the development and implementation of BCMM WC/WDM strategy, although the municipality has taken some step towards its implementation. However, the strives taken by BCMM in implementing water conservation and water demand management initiatives are acknowledged. The study provides recommendations related to the findings identified upon the data collection and fieldwork. The recommendation proposed by the study includes proper communicating the BCMM WC/WDM strategy to all relevant stakeholders, focus on reducing the non-revenue water, implementation of various project related to pressure management, encourage culture of using water efficiently through educational and community awareness campaigns, capacitation of BCMM including seeking financial support, continuous review of the strategy and exploring other water supply sources to relax the already constrained existing water sources. The limitations of the study compared to the broader scope of water conservation and water demand management aspects are highlighted and acknowledged. Thus, in the conclusion of this study, further future studies are suggested to explore other related aspects of water conservation and water demand management in BCMM. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2021

- Description: Physical Education (PE) is vital for the holistic development of Foundation Phase learners. Foundation Phase teachers working in low resource contexts, however, being generalists rather than specialists, struggle to teach PE effectively, even when supplied with programmes by external experts. I was interested in finding out why, and what could be done to help them integrate Fundamental Movement Skills (FMS) into their teaching, to benefit their learners. I proceeded from the hypothesis that teachers should play an active part in their own development, otherwise any Continual Professional Teacher Development (CPTD) would not bring about the change desired. I argued that if CPTD training and support is embedded within their context and based on teaching philosophies that foster teacher transformation, empowerment, and advocacy, then teachers might be more likely to commit to teaching PE. My aim in this study was thus to develop a collaborative process of CPTD with Foundation Phase teachers in low resource schools to enrich their pedagogical content knowledge (PCK) of PE and FMS within their contexts of social disadvantage. I initially adopted a qualitative design, but during this study, I realised that a more participatory approach was needed. I therefore present my study in two phases In Phase One, I answered the question: What are Foundation Phase teachers’ experiences of implementing PE in low resource schools? I did so to inform the design of an appropriately suited CPTD model for Phase Two of this study. I used a qualitative research design situated within the interpretive paradigm. I purposively sampled 24 Foundation Phase teachers to partake in semi-structured interviews. Thematic analysis revealed three broad themes, namely, personal, and systemic barriers to PE, as well as positive responses to challenges. The overlap between themes was significant, highlighting the complexity of teachers’ experiences and perceptions of PE. Teachers’ positive responses emphasised that they possess the creativity and advocacy to overcome challenges posed and necessitated that I adopt a participatory design to work with teachers to develop a collaborative form of CPTD. Phase Two of this study was guided by the questions set by the participating teachers. Ten Foundation Phase teachers from two schools volunteered to be part of the study. In Cycle One they asked: What do we need to learn to be able to effectively implement PE? The findings of Cycle One led them to ask the following question in Cycle Two: How can we improve our confidence to teach PE within our school contexts? Participants did so through collaboratively creating PE lessons which they then implemented and evaluated. The findings of Phase Two highlighted how Foundation Phase teachers can be guided to empower themselves to overcome the barriers to teaching PE that they face in their low resource schools. Based on teachers’ CPTD experiences, I then addressed the third question of this study: What CPTD guidelines can be generated to enable Foundation Phase teachers to improve on and to implement their PCK of PE and FMS at low resource schools? Five CPTD guidelines aimed at collaborative and transformative PE-based CPTD focused on whole school transformation were identified. I provide a graphic depiction of the CPTD guidelines that explains how it can be operationalised. These CPTD guidelines and process model provide valuable knowledge to inform CPTD policy and practice of PE in the Foundation Phase in low resource schools. , Thesis (PhD) -- Faculty of Health Sciences, 2021

- Description: In South Africa, a severe shortage of professional engineers exists compared to the international benchmark of an average population per engineer. This shortage is one of the major causes of poor service and utility delivery at the municipal level. In addition, there is an insufficient number of competent engineers available for ongoing projects. Hence, there is a critical shortage of experienced, engineering professionals, particularly mid-career engineers to be responsible for production works. As a result, Universities of Technology (UoT) were tasked and authorised to train engineering professionals. From research, it was discovered that most of the Civil Engineering Graduate Technicians (CEGT) failed to acquire and develop relevant and essential industry skills during their engineering programme. This makes it difficult for them to be employed in the engineering workplaces. The departments of civil engineering in some South African universities have not evaluated the quality of the education of their CEGT and their employability to work in the engineering industry. This research therefore aims to measure the employability and quality of education of Civil Engineering Graduate Technicians from some South African universities by investigating the experiences of civil engineering alumni and employers of graduates in the engineering industry. This is to determine if the graduate technicians are provided and equipped with relevant industry competencies and skills set to meet the industry’s expectation. An online survey which contains 89 closed-ended questions was designed to allow alumni and their employers assess the standard of education of graduates and industry competence acquired during their engineering programmes. The Universal Resource Link (URL) to the online questionnaire was sent to a sample of 600 respondents using a web-based survey approach. Only seventeen percent of the targeted population completed the survey and that makes 102 respondents in this study. A conceptual model that measures the employability of Civil Engineering Graduate Technicians was also developed. The data gathered was statistically analysed. Varying descriptive and inferential statistics were explored, such as frequency distributions, central measure, dispersion measure, the Cronbach alpha coefficient test, one-sample t-tests, Cohen’s d, Pearson’s product moment correlation, ANOVA, MANOVA, ranking indices and lastly, Exploratory Factor Analysis (EFA). The EFA was employed to ensure the construct validity of the instrument and to identify items which should be removed. Each of these statistics cumulatively performs an empirical evaluation of the Civil Engineering Graduate Technician employability model. From the result of the data analysis, the hypothesised model identified the following factors as having an influence on the employability of Civil Engineering Graduate Technicians: Knowledge Gained, Academic Staff Teaching, Engineering Design Ability, Individual and Teamwork Ability, Participation of each Student, Infrastructure Provided, Problem Solving Skills, Professional and Technical Communication Skills, Workplace Practices, Encouragement in School and Essentiality of Creativity and Innovation. These eleven independent factors from Cronbach’s Alpha coefficient were all found to possess good internal reliability. They all exert a significant positive effect on employability. Additionally, managerial recommendations, limitations to the study and a call for future research were discussed. If these recommendations are implemented, UoTs and employers in the civil engineering industry should be successful in producing work-ready civil engineering technicians. Having these recommendations implemented is fundamental to creating innovative and skilled technicians and engineers in the engineering industry, who can adapt to market changes. Of the competencies assessed, “Individual and Teamwork ability” received the highest and “Infrastructure provided” the lowest rating. Overall, the results indicate that employers are reasonably satisfied with the competencies of Civil Engineering Graduate Technicians but point to the need for the strengthening of “Engineering design ability”, “Professional and technical communication skills” and “Infrastructure provided” competencies within the curriculum of the Diploma programme. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business Administration, 2021

Harvey (1930-1978), was an American Gay Rights activist who became one of the first openly gay political candidates to be elected to public office in the United States in 1977, before being assassinated in 1978. The study was conducted within a postmodern Social Constructionist epistemology which applied Michael White and David Epston’s (1990) Narrative Therapy as a particular theoretical lens to understand Harvey’s lived experiences. Harvey was chosen as the research subject based on his ability to construct his public identity as an openly gay politician and activist in defiance of the contemporarily dominant heteronormative discourse, despite the danger this posed to his personal safety. His selection was made through purposive sampling which facilitated a qualitative, single case psychobiographical study. Data on Harvey was obtained from both primary and secondary sources available in the public domain, and was analysed using Narrative Therapy concepts that describe individual identity. The study’s findings detail the narrative processes Harvey underwent and the discursive influences he experienced to move from being a closeted gay man, who hid his sexuality from public view, to an openly gay trailblazing Gay Rights activist, who fiercely challenged the norms and effects of heteronormativity on both his own life and that of his gay community. The study emphasises the value of psychobiography and Narrative Therapy to understand individual identity construction and performance. , Thesis (MA) -- Faculty of Health Sciences, 2021

- Description: This study sought out to empirically investigate whether it is export diversification or export concentration that would help achieve and sustain higher economic growth in the G20 countries using data over the period of 1995 to 2017. The empirical analysis uses the Autoregressive Distributed Lag (ARDL) model within a Pooled Mean Group (PMG) to evaluate the existence of a long run cointegration and as a baseline for examining whether the relationship between export diversification (concentration) and growth is nonlinear through a Nonlinear Autoregressive Distributed Lag (NARDL) model. The ARDL model confirms that the is a long run cointegration between the variables where both export diversification and concentration have a positive impact on growth. On the other hand, the NARDL model confirms that the relationship between export diversification and growth in the G20 countries is a nonlinear where a positive change in diversification has a negative effect on growth, while negative changes have a positive effect, thus, diversification has a negative effect on growth. The NARDL results for concentration do not confirm any nonlinearities, this implies that both positive and negative changes in concentration have negative and statistically insignificant effects on growth. Both the panel ARDL and panel NARDL model are superior models that can account and correct any serial autocorrelation that may exist, thus making the results robust enough. Seemingly, that both export diversification and concentration have a negative effect on growth and this effect may be attributed to the sample being a mixture of developed and developing economies, the study further analysed the effect on to sub-samples (G7 and non-G7). The results for the G7 panel show that there is no evidence of a nonlinear relationship between growth and concentration, as a positive change has a positive effect and a negative change has a negative effect. Overall, the G7 NARDL results are show that concentration will accelerate growth in developed economies in the long run more than diversification. The results for the non-G7 panel the NARDL results show that there is a linear relationship between export diversification (concentration) and growth. The overall, results of the study suggest, that for the G20 countries developmental levels need to be considered in order to know the correct export composition strategy to adopt in order to accelerate growth. With that said, in developed countries like the G7 export concentration would be beneficial in accelerating growth, while in developing countries like the non-G7 countries export diversification would accelerate growth. , Thesis (MCom) -- Faculty of Business and Economic Sciences , Economics, 2021

- Description: Literature has revealed that indigenous learners, especially in many African nations are subjected to learning school science in unfamiliar contexts. Learners in Namibia where this study was conducted are no exception. In consequence, learners experience cognitive conflict between school science and the experiences learnt at home and in the community. This is exacerbated, in part, by the fact that science teachers do not seem to know how to integrate indigenous knowledge in their science teaching. As an attempt to address this problem, some scholars call for the integration of indigenous knowledge into the science curriculum to provide a much needed context for learning science. It is against this background that this study sought to use the indigenous technology of dyeing and weaving baskets as a cultural tool to mediate learning of chemical and physical changes. Underpinned by the interpretivist and Ubuntu paradigms, the study employed a qualitative case study research design. The study was conducted in the Zambezi region in Namibia. Four grade 8 Physical Science teachers, an expert community member, and a critical friend were involved as participants in this study. Data were gathered using semi-structured interviews, workshop discussions, participatory observation, and journal reflections. Vygotsky’s socio-cultural theory and Mavhunga and Rollnick’s topic specific pedagogical content knowledge were used as theoretical and analytical frameworks, respectively. A thematic approach to data analysis was employed to come up with sub-themes and themes. The findings of the study revealed that all the participating teachers in this study had never been exposed to ideas on how to integrate indigenous knowledge in their science teaching. As a result, they all embraced and valued the indigenous technology of dyeing and weaving as relevant and useful in the teaching and learning of chemical and physical changes. This study recommends that there is a need to empower science teachers on how to integrate indigenous knowledge in their science teaching in order to make science accessible and relevant to their learners’ lived worlds. , Thesis (MEd) -- Faculty of Education, Education, 2021

- Description: The study evaluated the product-dust levels that were released from manufacturing equipment during routine manufacturing of highly potent active pharmaceutical ingredients. The study was performed at a high containment manufacturing facility for Product X. These assessments are necessary to evaluate the level of containment performance in correlation with health-based exposure limits; and from this, to develop proper control strategies for the workplace. The equipment that was evaluated in this study included barrier systems (isolators, isolation boxes), dust-proof decanting systems (split valves), soft connections covered with continuous liners, and airtight intermediate bulk containers. Methodology The amount of uncontrolled product-dust that was released during the manufacturing process was quantified by establishing an air and surface monitoring programme. This was then compared to health-based exposure levels (HBEL’s) to ensure operator safety and to implement an effective control strategy. Air monitoring involves the sampling of airborne particles through filtration of the air with a filter using a sampling pump to draw a quantifiable volume of air through the filter. The filter is then tested in a laboratory which extracts and quantifies the amount of highly potent active pharmaceutical ingredient (HPAPI) on the filter. Surface monitoring is used to assess the level of product contamination on a surface. The technique uses a suitable adsorbent material to physically adsorb surface contaminants from the surface by wiping or swabbing. Protocols were designed based on a risk assessment that took the manufacturing process, literature, and facility design into consideration. Results The HBEL level of 0.2 μg/m3 that was calculated for the manufacturing process of Product X was found to be lower than the HBEL of 1.4 μg/m3; and consequently, the level of operator exposure was well within the acceptable occupational exposure limits. All surface monitoring results passed the acceptance criteria of less than 0.032 mg/100 cm2 except for excursions that occurred during breaches in containment. Conclusion The air monitoring programme facilitated the quantification of the product-dust levels that were released into the primary manufacturing areas; which could then be verified against the HBEL of Product X. The surface monitoring programme facilitated the quantification of the product residue on non-product contact surfaces in the facility; which could then be verified against the HBEL of Product X. The objectives of the study were met for Level 2 of the high containment suite as it was possible to calculate the product-dust released from the manufacturing equipment and the product residue on external equipment surfaces and non-product contact surfaces in order to verify these levels against the relevant HBEL’s. The study enabled the assessment and impact on the current control measures, and recommendations were given to develop the control strategy. , Thesis (MPharm) -- Faculty of Health Sciences, 2021

- Description: Work gratification and expectancies are of the utmost importance to the skilled workforce in the South African construction industry. The price paid for a demotivated workforce in this industry is very high and it leads to friction in the workplace, displeasing work outcomes and time delays. Furthermore it leads to increased incidences of theft,absenteeism and outputs that arebelow standard in terms of productivityand thequality of the work.In order to motivate the workforce in the construction industry,a day-by-day, step-by-step,hands-on approachmust be used. The aforesaid aids site managers to manage effectively and this in turn leads to an increase in production by way of enhanced productivity. Research shows that a correlationbetweenmotivation, excelling at work, improved productivity and fulfilment and expectancyexist. The reason why individuals act in a specific manner and choose not to act in a certain way can be directly linked totheirmotivation and engagement.As a member ofthe construction industry in South Africa, Stefanutti Stocks isseen as one of the leading construction groups. Employing more than 12 000 workers it has the ability to provide a wide variety of different scale projects for a host of clients in varied markets. The division concentrated on in this study is the Roads, Pipelines and Mining Services (RPM)Business Unit. The MD of the RPM Business Unit when starting at the company a few years ago came to the conclusion that in order for the RPM Business Unit to function optimally certain business inconsistencies regarding employee engagement needed to be addressed. Based on this he decided to use a consulting firm, AIM,to establish what the exact concernswere and what interventions wererequired to deal with them. ivInterventions facilitatedby AIM includedManagement Training Programmes and Workshops as well as one-on-one coaching sessions with selected individuals.The methodology used in this study was to measurethe current level of employee engagement subsequent toengagement interventionsconcludedby AIM.The approach used was the use of surveys distributed through AIM in conjunction with the RPM Business Unit’sHR Department.

- Description: In the rapidly changing world of cybersecurity, the constant increase of vulnerabilities continues to be a prevalent issue for many organisations. Malicious actors are aware that most organisations cannot timeously patch known vulnerabilities and are ill-prepared to protect against newly created vulnerabilities where a signature or an available patch has not yet been created. Consequently, information security personnel face ongoing challenges to mitigate these risks. In this research, the problem of remediation in a world of increasing vulnerabilities is considered. The current paradigm of vulnerability and patch management is reviewed using a pragmatic approach to all associated variables of these services / practices and, as a result, what is working and what is not working in terms of remediation is understood. In addition to the analysis, a taxonomy is created to provide a graphical representation of all associated variables to vulnerability and patch management based on existing literature. Frameworks currently being utilised in the industry to create an effective engagement model between vulnerability and patch management services are considered. The link between quantifying a threat, vulnerability and consequence; what Microsoft has available for patching; and the action plan for resulting vulnerabilities is explored. Furthermore, the processes and means of communication between each of these services are investigated to ensure there is effective remediation of vulnerabilities, ultimately improving the security risk posture of an organisation. In order to effectively measure the security risk posture, progress is measured between each of these services through a single averaged measurement metric. The outcome of the research highlights influencing factors that impact successful vulnerability management, in line with identified themes from the research taxonomy. These influencing factors are however significantly undermined due to resources within the same organisations not having a clear and consistent understanding of their role, organisational capabilities and objectives for effective vulnerability and patch management within their organisations. , Thesis (MSc) -- Faculty of Science, Computer Science, 2021

Making Sense of Barkhuizen 2 : An Investigation into the Public Policy Defence of ‘Unfair Enforcement’ in South African Law, with Reference to the Law on Covenants in Restraint of Trade

- Description: This thesis investigates the application of the public policy test for determining the enforceability of a valid contractual clause established in Barkhuizen v Napier. After analysing the historical development of the application of the doctrine of public policy, the study examines the conceptualisation and application of the public policy test in the leading cases in South Africa. The study then provides an analysis of the recent judgment of Beadica 231 CC and Others v Trustees for the time being of the Oregon Trust and Others, which outlined the current legal position on the proper constitutional approach to the judicial enforcement of valid contractual clauses. The study argues that, although the Constitutional Court in Beadica provided some clarity on what public policy is in modern South African law, it did not, from a practical point of view, set out the method that should be used to adjudicate such cases. The study thereafter suggests that, to address this issue, our courts should consider developing a methodological approach to measuring public policy in unfair enforcement cases. To support this proposition, the study examines the law on determining the enforcement of restraint of trade agreements. It is argued that, within that context, the courts have formulated a methodological approach in the form of a list of standard questions that a judge should ask when determining the enforceability of a restraint clause. The thesis then closes with a case study, using guidelines established from the approach in restraint cases, to illustrate how the proposed guideline may be formulated, and how it could be applied in general unfair enforcement cases. The thesis argues that a practical guide of this nature would serve as a useful tool for judges to use when faced with a claim relating to the unfair enforcement of a valid clause other than a restraint clause, and would thus ensure consistency in contractual enforcement analysis in South Africa. , Thesis (LLM) -- Faculty of Law, Law, 2021

- 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 “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: This thesis shows the statistics of atmospheric gravity waves (AGWs) observed in the OI emission 557.7 nm at _97 km altitude using an all-sky imager based in Sutherland, South Africa (32.37_ S, 20.81_ E) in the year 2017. The wavelengths were determined using the propagation vector method, velocity was determined using the cross correlation of 1D FFT and the period was determined using the equation that relates wavelength and velocity. It was found that the horizontal wavelength in summer was almost evenly distributed between 10 and 40 km and for autumn, winter and spring were mostly between 10 and 30 km. The favoured speeds were between 40 and 50 m/s in autumn, as well as 30 and 50 m/s in summer, but the AGWs in winter had a bimodal speed distribution of 20 - 40 and 50 - 70 m/s. The majority of periods observed in all seasons were less than 20 minutes with a dominant peak of 5 - 10 minutes in autumn and spring. There was no favoured propagation direction for spring, but AGWs favoured a southeastward propagation in summer, and a southward propagation in autumn and winter. , Thesis (MSc) -- Faculty of Science, Physics and Electronics, 2021

- Description: The current study focused on the representation of women in isiXhosa drama books. The aim of the study was to understand how women are represented in these post-1990 dramas written by both female and male authors. Furthermore, the study aimed to look at whether the authors took note of developments made by African women in a broader context such as social, political, spiritual and economic spheres. The study followed a pragmatic approach which is useful to analyse drama, the meanings and the events related to situations. A discourse analysis was also applied as it is difficult to separate it from pragmatics. This means that the study outlined the correlation of pragmatics with discourse analysis and drama. Four isiXhosa books were selected which are Iinkunzi ezimbini by Hlumela Mothlabane 1994, Yeha mfazi obulala indoda 1997 and Kuphek’amadoda kupheth’abafazi We-ena! 2007 by Lubabalo Livingstone Ngewu and Imida by Nompumezo Buzani 2016. Episodes from the four selected isiXhosa drama books were identified. Upon identifying the episodes, they were categorised in to themes in order to highlight the representation of women in the books. This was done using a qualitative research method because it useful to be used in natural setting to understand meanings and social life. Many themes were identified in the four selected isiXhosa drama books. The dominating themes are women who are educated, employed and do not tolerate ill treatment. This shows that the authors in a way are paying attention to the events occurring post-1990 as some of these were not popular pre-1990. The study acknowledges that there is limited research conducted that analyses drama books from both male and female authors. Therefore, future studies could look into this. , Thesis (MA) -- Faculty of Humanities, School of Language & Literatures, Education, 2021

- Description: The separation of [IrCl6]2- from [RhCl5(H2O)]2- by silica microparticles functionalized with 1,10-diamindecane (C10) and quaternized with 4-nitrobenzylchloride (NO2Benz) in various hydrochloric acid mediums was investigated by continuous column studies. The sorbent materials were synthesized using three different routes: Synthesis route 1 (NaI catalyzed synthesis of diammonium functionalized silica microparticles), Synthesis Route 2 (via silylazation of silica followed by functionalization) and Synthesis Route 3 (silane-based sorbent material). The functionalized sorbent materials were characterized by NMR, Microanalysis, SEM-EDS, FT-IR, TGA and BET surface area. The separation efficiency of the quaternary diammonium cations was investigated under dynamic flow adsorption conditions. Preliminary ICP-OES runs were done, at 6 M HCl, to assess which synthesis route gave the best performing sorbent material. [IrCl6]2- selectivity of the sorbent materials was achieved by washing with an HCl solution to remove unadsorbed metal species, then stripping off the [RhCl5(H2O)]2- with 0.05 M of sodium chlorate and the iridium species was eluted with a 20% HCl solution. From the preliminary ICP-OES, loading capacities were calculated, and it was observed that the three sorbent materials from synthesis route 2 (13.89 mg/g for (4) SSC10NO2Benz-A, 1.44 mg/g for (5) SSC10NO2Benz-HoA, and 1.0859 mg/g for (6) SSC10NO2Benz-DoA) showed the highest uptake of [IrCl6]2- and route 1 (1.89 mg/g for (1) SSC10NO2Benz-A, 1.25 mg/g for (2) SSC10NO2Benz-HoA and 0.99 mg/g for (3) SSC10NO2Benz-DoA ) and Route 3 (0.55 mg/g for (7) SC10-AI and 0.755 mg/g for (8) SC10-ACl) materials did not perform efficiently enough, thus were not used further for the HCl study. Within synthesis route 2, three sorbent materials were evaluated, which had varying quantities of the cation: SSC10NO2Benz-A (having a quantity previously used in our research and denoted A), SSC10NO2Benz-HoA (having a quantity Half of A) and SSC10NO2Benz-DoA (having a quantity double of A). SSC10NO2Benz-A showed the highest loading capacity than SSC10NO2Benz-HoA and SSC10NO2Benz-DoA; HCl studies were carried out using SSC10NO2Benz-A. HCl solution having different concentrations (5, 5.5 , 6 , 6.6 and 6.8 M) were used to prepare the metal solutions. This was done to assess which HCl concentration gave the best metal solution containing high amounts of [IrCl6]2- and [RhCl5(H2O)]2-, which would result in a more efficient separation. An auto titrator was used to standardize the HCl concentrations, and the metal ion chloride species solutions were determined by UV-Vis, and their concentrations were confirmed with ICP-OES. Column sorption of iridium and rhodium on SSC10NO2Benz-A using these HCl solutions was carried out, and loading capacities of [IrCl6]2- were obtained. The loading capacities of the 5 M, 5.5 M, 6 M, 6,6 M and 6.8 M HCl solutions for [IrCl6]2- were 2.64, 4.01, 13.89, 18.15 and 7.23 mg/g, respectively. The optimum separation conditions were thus determined by investigating effective parameters such as the method of synthesis, silica to cation ratio, HCl concentration and flow rate. This thesis presents quaternary diammonium sorbent materials that could be applied in feed solutions from ore processing for iridium recovery. , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2021

- Description: The role of healthcare workers (HCWs) is to render services to the sick. While executing their duties, these HCWs can fall ill due to various occupational exposures. HCWs are exposed to a range of hazards including physical, biological, chemical and ergonomic hazards. These hazards can cause physical injuries, diseases, mental strain and other adverse health effects.: The aim of this study was to assess the prevalence of occupational hazards amongst HCWs in urban and rural areas of the KwaZulu-Natal province, South Africa: A descriptive cross-sectional research design was utilised on the estimated sample size of 270 respondents, from ten public hospitals. The sampling method used to identify participants was convenience sampling and data was collected through a self-administered, semi-structured questionnaire. The analysed data was presented in descriptive and inferential summary statistics. The data was analysed using graphical and numerical descriptive statistics as well as inferential statistical techniques. The statistical significance was set at P0.05. The results revealed that both urban and rural HCWs were exposed to physical, biological, chemical and ergonomic hazards. Overall, physical hazards were the most frequently reported form of hazard exposure at 98,6%, followed by biological hazards (96,7%), ergonomic hazards (94,4%) and chemical hazards (23,7%). The duration of exposure to hazards varied from 12 months to 5 years. In a period of 12 months, radiation, cold, heat, slips and trips were the most common sources of physical hazard exposure while direct contact with patient bodily fluids was the most common source of biological hazard exposure and mercury was the most common source of chemical hazard exposure. More than a quarter of the HCWs had experienced some form of assault by a patient in the preceding 12 months. Over a three-year period, both urban and rural area HCWs reported the use of post-exposure prophylaxis and experienced symptoms of chemical exposure at work. Less than 6% of the HCWs had developed an occupational disease in the previous five years. There were no statistically significant differences in total exposure to hazards between urban and rural area HCW. , Thesis (Mtech) --Faculty of Health Sciences, School of Behavioural Sciences, 2021

- Description: This treatise discuses, the effectiveness of the Prevention of Organised Crime Act (POCA), specifically, Chapter Four of the Act. POCA was enacted for the purposes of tackling, inter alia, the threat posed by money laundering, racketeering and criminal gang activities. Moreover, POCA was enacted to supplement the common law, specifically the doctrines of common purpose, conspiracy, public violence as well as incitement. In this respect, the legislative framework in line with POCA- aimed at addressing money laundering and racketeering have contributed significantly in addressing such crimes. However, the same cannot be said about its effect on dealing with criminal gang activities. The criticisms which have been raised for the increase of criminal gang activities are that the sentences provided for in Chapter Four of POCA are viewed as inadequate in terms of deterrence because they are too lenient. The sentences do not hold gang leaders accountable but rather focus on foot soldiers. Likewise, POCA is similar to and does not expand the common law.

- Description: This treatise discuses, the effectiveness of the Prevention of Organised Crime Act (POCA), specifically, Chapter Four of the Act. POCA was enacted for the purposes of tackling, inter alia, the threat posed by money laundering, racketeering and criminal gang activities. Moreover, POCA was enacted to supplement the common law, specifically the doctrines of common purpose, conspiracy, public violence as well as incitement. In this respect, the legislative framework in line with POCA- aimed at addressing money laundering and racketeering have contributed significantly in addressing such crimes. However, the same cannot be said about its effect on dealing with criminal gang activities. The criticisms which have been raised for the increase of criminal gang activities are that the sentences provided for in Chapter Four of POCA are viewed as inadequate in terms of deterrence because they are too lenient. The sentences do not hold gang leaders accountable but rather focus on foot soldiers. Likewise, POCA is similar to and does not expand the common law. This treatise aims to demystify the issues relating to criminal gang activities in South Africa. It investigates the extent to which Chapter Four of POCA adds significant value to the common law in respect of criminalising criminal gang related activities. It concludes and make recommendations on how criminal gang activities can be tackled while upholding South Africa’s constitutional values.bstract text. , Thesis (LLM) -- Faculty of Law, Criminal and Procedural Law, 2021
