Exploring teachers’ classroom management strategies to enhance teaching and learning in Gauteng Province
Get PDFClassroom management strategies in teaching and learning are still a challenge in most high schools. The study investigates how classroom management strategies can be enhanced towards effective teaching and learning in Gauteng Province, South Africa. The research is lenses within an interpretive paradigm and was conducted using a qualitative approach, and a case study research design was employed. The study employed purposive sampling to select relevant participants from high schools. The participants consisted of twelve teachers from three chosen schools in Gauteng Province in the Ekurhuleni North District. Each school had four teachers as participants, making a total of twelve participants. Semi-structured interviews were conducted to elicit information from the participants. Content analysis was applied to analyze and evaluate the data from the conducted semi-structured interviews. The findings were as follows: teachers' ineffectiveness affects classroom management, especially when there is a lack of planning, poor time management, and poor relationship between the learners and teachers. It is suggested that teachers need to take charge of knowing what roles to play, such as being the controller, assessor, and organizer in the classroom setting. Recommendations were made to address the implementation of classroom management strategies in the classroom, whereby active teaching and learning need to take place in the schools. Therefore, it is possible for teachers to successfully implement classroom management by always being flexible, such as being able to read the classroom environment, implementing necessary discipline measures without attracting attention to themselves or interrupting the class session, and prioritizing professionalism always.Thesis (Masters) -- Faculty of Education, 202
Leverage points for meaningful participatory governance: lessons from the Tsitsa River catchment, South Africa
Get PDFSouth Africa underwent the renowned transition into a representative multiracial democracy in 1994. While there has been notable progress in many developmental aspects of South African society, many inherited dilemmas persist, and myriad novel ones are emerging. In land and water governance, the nascent institutions do not reflect the visions laid out in the pioneering and substantive legislation, policies, and guidelines generated in the post-1994 period. Unaddressed dilemmas include widespread failures in local water governance, persistent inequality of access to land and water, poor or non-existent service delivery in rural areas, underdeveloped institutions for integrated and inclusive water resource management, and pernicious divisions between institutions. Overcoming these challenges, which are embedded in complex social-ecological systems across South Africa, will require the collaborative effort of diverse actors from different levels and sectors of society. So how do we foster meaningful participation in ways that are not tyrannical, tokenistic, or manipulative? How do we build local institutions that make sense in the broader political system and in the lives of rural residents? How do we support institutions that meaningfully include diverse voices and enable tangible development outcomes? This thesis explores these questions as part of the Tsitsa Project, a transdisciplinary landscape management project working in the Tsitsa River Catchment (TsRC) in the rural parts of the Eastern Cape province of South Africa. Based on the valuable water resources, severe ecosystem degradation, overlapping traditional and democratic governance systems, and impoverished population, the TsRC is a worthwhile candidate for in-depth study paired with innovative efforts towards systemic development. The single place-based case study approach drew on systems thinking within an evolving transdisciplinary methodology. Qualitative data were collected through extended fieldwork and analysed through an adaptive and iterative approach. Governance mapping elucidated the multiple levels of governance, and a systemic analysis explored meaningful participation at the local level through causal diagramming and observation-based narratives. From the findings, a synthetic analysis identified high leverage points to enable participatory governance interventions to have more sustained impacts. Governance manifestations in the TsRC generally align with existing descriptions of the fractures and associated dilemmas across South Africa, with the added complexities of being a rural landscape in which democratic and traditional governance systems overlap and interact. Local participatory institutions need to endure the broader instability and dysfunction. Interventions must, therefore, be oriented towards trust building and shared understanding while using more practical interventions that provide tangible outcomes, enable in-practice capacity development, and support platforms for all actors to experience and practice meaningful participation together. This thesis aims to unearth the lessons that one small rural catchment might hold for the governance of complex, contested land and for water governance contexts more broadly.Thesis (PhD) -- Faculty of Science, Institute for Water Research, 202
Evaluation of potential oviposition deterrents for false codling moth, Thaumatotibia leucotreta (Meyrick) (Lepidoptera: Tortricidae)
Get PDFThere has been extensive research on the use of semiochemicals as deterrents or true repellents in insect pest management, particularly in push-pull strategies. Much of this research has focused on pests of medical and veterinary importance and has been limited for agricultural pests. This means there is an opportunity to study use of deterrents to manage pests of agricultural importance. No study has been conducted on deterrents for false codling moth (FCM), Thaumatotibia leucotreta (Meyrick) (Lepidoptera: Tortricidae), a key phytosanitary pest in citrus orchards across South Africa. This study assessed FCM oviposition deterrence in botanicals (plants (n = 11) and essential oils (n = 15)), and some commercial pesticides (n = 7) used for FCM control in South Africa. All tested botanicals were selected based on an extensive literature review of plant compounds that have been reported to deter or repel lepidopteran pests. Choice and no-choice oviposition bioassays were conducted in complete darkness in a controlled environment room. Oranges treated with solutions/suspensions of potential oviposition deterrents were placed into a cage with gravid FCM females for four hours, with oviposition being recorded every hour. Of the 33 tested compounds, only eight significantly reduced FCM oviposition (P < 0.05) compared to the control in oviposition bioassays i.e. two essential oils (lavender and peppermint), two plant crude extracts (garlic and marigold), one fruit (Mango), and three commercial FCM insecticides (Delegate, Coragen, and Warlock). All identified oviposition deterrents, except for Mango, were further investigated for their ovicidal properties in concentration response bioassays, where all botanicals were identified to have dual action (both deterrent and ovicidal properties), as they significantly (P < 0.05) reduced FCM oviposition and egg hatch. Garlic was the most efficacious botanical whilst Warlock was the only commercial insecticide that did not show ovicidal activity (F = 41.17, P = 0.0622). Larval penetration of the host fruit was less than egg hatch for all tested compounds in concentration response bioassays. Oviposition, egg hatch, and larval penetration were all affected by concentration, with the higher concentrations being the most effective. The efficacy of these deterrent compounds should be further tested in semi-field and/or field trials, and they may have potential in FCM management as allomone dispensers or sprays. They can also be implemented in push-pull strategies where they can be used in conjunction with FCM attractants. Lastly, repellence studies should be conducted in absentia of the host fruit to determine whether oviposition deterrence was a result of true repellence or odour masking.Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 202
The impact of fiscal and monetary policies on manufacturing sector performance in South Africa
No full textRegulatory authorities have to date utilised a strategic blend of fiscal and monetary policies in dealing with the unique set of macroeconomic conditions facing South Africa. Government policy intervention has significant implications for economic growth and output within the manufacturing environment. Heterogeneity has also been discerned in relation to the responsiveness of various industries within the manufacturing sector towards both fiscal and monetary policy variable variations. However, given weakened growth prospects, policy alignment issues have been observed. The purpose of this study was firstly, to examine the impact of fiscal and monetary variables on manufacturing sector output in South Africa and secondly, to analyse the manufacturing industry significance of the various monetary transmission mechanism channels. The study made use of quarterly and monthly data to achieve these stated objectives, dated between 1998 and 2020. To achieve the first objective, the study employed the Autoregressive Distributed Lag (ARDL) model given the order of integration of the variables. The empirical results revealed significant, positive relations between tax revenue, deficit financing, nominal effective exchange rate (NEER) and money supply (M3) for total manufacturing (LTOTAL). Contrastingly, there were negative links between LTOTAL, government spending and the lending rate. At a disaggregated industry level, there were positive relations with tax revenue in food and wood industries, although tax revenue was significantly negative for metals. Likewise, to LTOTAL, linkages with spending were significantly negative for wood and metal industries but positive for chemicals. Negative spending signage could be a result of crowding-out. For deficit financing, positive associations within chemicals did not conform to expectations. Similarly, to LTOTAL, wood and metal industries conformed to expectations of negative relations with the lending rate. In respect of the NEER in food and wood production, significant, positive links were established. Contrastingly, a negative linkage existed for chemical activities at the 5% level. Concerning M3 and akin to LTOTAL, the relation with metal industries was positive. However, negative findings for food and chemicals contradicted expectations, suggesting money supply was not efficiently utilised in managing monetary variables in the long-term. The second objective of the study focused on analysing manufacturing industry significance of the various monetary transmission mechanism channels. The Vector Error Correction Model (VECM) were employed to analyse the relationship between the variables. Impulse response and variance decomposition were also constructed to further trace which channel is more significant in influencing manufacturing output. The empirical results revealed that the interest rate channel occupied a relatively significant role in both LTOTAL and several selected manufacturing industries. Shocks accounted for 9.71%, 11.96% and 14.28% of the variance in LTOTAL, metal and chemical industries. The asset price channel also appeared relatively significant, with shocks to the FTSE/JSE all-share index explaining 18.21% and 21.13% of the variation in food and wood production, signifying the most relevant channel for these particular industries and representing the second most important channel for LTOTAL and the other remaining industries. The exchange rate channel also presented as being a more relevant channel for food and wood, but occupied little role in LTOTAL, whilst the credit channel was relatively ineffectual for both LTOTAL and all industries examined. The results obtained imply that government should exercise caution and demonstrate fiscal restraint and that the South African Reserve Bank (SARB) need to take greater consideration of output fluctuations in monetary policy setting. Research has dictated that an expansionary fiscal policy is generally required as a means to achieving increased growth. However, findings obtained at both the aggregate and disaggregated manufacturing level in South Africa largely varied. This implies significant heterogeneity within the South African manufacturing sector in respect of fiscal policy responses. Expansionary fiscal stimulus packages need to be better targeted towards industries that will most benefit. Similarly, monetary policy responses at the aggregate and disaggregated manufacturing level in South Africa were heterogeneous and furthermore, differed when examining combined policy impacts. There was also a heterogeneous response with respect to relevance of the channels, via which monetary policy operated, with the interest rate channel dominating. SARB do take into consideration output fluctuations in policy setting but this is not currently emphasised or legislated.Thesis (DCom) -- Faculty of Management and Commerce, 202
Postgraduate student experience and retention at South African public higher education institutions
Get PDFA country’s economic growth and global competitiveness as a knowledge-based economy can be enhanced by an educated workforce. Therefore, the completion of postgraduate qualifications is of high importance to any country. In South Africa, according to the Department of Higher Education and Training (DHET), it is necessary to improve postgraduate (PG) output and practice skills to promote socioeconomic development. Despite an increase in PG enrolments at public higher education institutions (PHEIs), South Africa reported an increase in PG student dropouts and therefore it is evident that student retention is a challenge. To foster student retention, the interactions between PHEIs and students on their student journeys are important since positive experiences can contribute to the retaining of students. The positive experiences of students depend on different aspects, challenges and dispositions during the student journey. The primary objective of this study was to investigate the variables that influence PG student experience for PG student retention at South African PHEIs. Based on an extensive review of the South African higher education landscape, marketing literature, also in the context of the study, a hypothesised model of the variables possibly influencing PG student experience for PG student retention was proposed. The four independent variables identified were higher education service quality, service design, student engagement and student satisfaction. The hypothesised model presented student experience as the intervening variable and student retention as the dependent variable. This positivistic study followed a deductive approach and a quantitative research methodology. During the empirical investigation, a survey strategy using a self-administered questionnaire collected data from a convenience sample of PG students registered at 15 South African PHEIs. A total of 435 usable questionnaires were returned and analysed statistically. Both descriptive and inferential statistics, including a Confirmatory factor analysis (CFA), Cronbach’s alpha, Pearson’s correlations, regression analyses, SEM for mediation as well as t-tests and ANOVAs, were employed in the data analysis.Thesis (PhD) -- Faculty of Business and Economic Sciences, School of Management Sciences, 202
A case study of how to implement continuous improvement initiatives
Get PDFThe aim of this study was to establish an understanding of the critical success factors of how to successfully implement and sustain continuous improvement projects at the Festive poultry processing plant using the 20 Keys continuous improvement (CI) tool. There are many continuous improvements in methodologies such as lean, 20 Keys , TQM and business process re-engineering. However, it has proven difficult for numerous businesses globally. Festive, a division of Astral Foods, a poultry processing plant, attempted to implement the 20 Keys , a continuous improvement methodology, and it was no exception as it was added to the list of unsuccessful companies. Because of the failed attempt to implement 20 Keys at Festive and many other manufacturing businesses, which attempted to introduce CI initiatives but ultimately failed, factors such as management support, training, rewards and recognition and organisational culture have been revealed by the literature review as contributors to continuous improvement initiatives’ successful or unsuccessful implementation. A case study methodology was applied in this study to understand the real-life context of the failed implementation of Continuous Improvement at Festive. Furthermore, it aimed to explore and explain complex causal links of training, rewards and recognition, organisational culture and management support which can positively impact the implementation of 20 Keys within the poultry processing industry or any manufacturing industry. A mixed method was followed through an online survey and in-depth interviews. The qualitative and quantitative data analysis results revealed that management support, training, rewards and recognition and organisational culture all were related and influenced continuous improvement implementation. Furthermore, companywide training, rewards and recognition proved to be the most significant challenge, resulting in the unsuccessful implementation of 20 Keys. The findings revealed that implementing continuous improvement is not immediate and entails all employees being adequately involved in the entire process from the start. The main finding at Festive was that when implementing the 20 Keys continuousThesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 202
Factors contributing to the productivity of operations at the port of Ngqura, Gqeberha
Get PDFPorts are the gateway to economic trade and a huge contributor to South Africa’s economy. Productivity has become a critical component for ports in the port industry as a means of enhancing market potential and competitiveness (Kuo, Lu, and Le, 2020). Therefore ports must investigate their productivity factors to stay competitive. This study sought to determine the factors that contribute to productivity at the Port of Ngqura. A qualitative research approach was employed in the study where data was obtained by conducting interviews with a sample of ten employees from Transnet Port Terminals and Transnet National Port Authority. Out of the ten employees identified, only four participants took part in the study. According to the respondents, the key factors contributing to productivity at the Port of Ngqura include the staff, efficient staff training, equipment, technology, and infrastructure. Furthermore, the respondents highlighted the importance of technology, specifically the planning and operations systems such as NAVIS and SPARCS, in optimising productivity. Infrastructure was also emphasised as a significant factor affecting productivity. Only the views of employees working at the Transnet Port Terminals and Transnet Port Authority at the Port of Ngqura were considered. The study achieved a low response rate. Based on the empirical research, the study could conclude by making the following recommendations that the Port of Ngqura should prioritise enhancing its operations by making significant investments in equipment and infrastructure. Through the adoption of an efficient human resource strategy, the port should also handle workforce problems brought on by resignations, voluntary separation plans (VSPs), and contract terminations. Planning for succession effectively is crucial to maintaining institutional knowledge.Thesis (MPhil) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 202
Eco-leadership determinants necessary for effective sustainability implementation
Get PDFSustainability is regarded globally as one of the key focus areas for organisations and requires also considering environmental and social performance in addition to economic performance. Eco-leadership is required to ensure operations impact society and the environment in a positive manner, in particular in the retail sector as customers have become conscious of their purchases being produced sustainably. The main objective of this study was thus to explore eco-leadership determinants necessary for sustainability implementation in retail organisations. The research was aimed at expanding knowledge about how retailers can implement or improve their sustainability status by following an eco-leadership approach. A literature review was conducted on what leadership in organisations entailed and how it can be described in terms of leaders’ characteristics, work practices and decisions. In addition a review on, leader qualities and leadership styles in general and of change leaders such as eco-leaders, sustainability strategies from both an environmental and socially responsible view in general and of the retail sector, was provided. The study followed a qualitative research approach using purposive sampling to identify the 11 participants from across the provinces in South Africa and retail product categories comprising of two hard-line retailers, five soft goods and consumables retailers, three FMCG retailers and one art retailer. A semi-structured interview guide was utilised to gather primary data using face-to-face, telephonic and email interviews. Content and constant comparative analysis was used to analyse the data. It appears that retailers ascribe eco-leadership in relation to resource management-, being people centred and practising sustainability leadership. All retailers seem to demonstrate their commitment to eco-leadership and serve society. Their sustainability status is publicised via digital and print media or visually displayed in-store. They practise eco-leadership as it is beneficial for their reputation or to ensure business continuity. Retailers use innovation and incorporate eco-leadership into their business models and have further plans to improve their sustainability.Thesis (PhD) -- Faculty of Business and Economic Sciences, School of Management Sciences, 202
Influence of digital marketing activities on brand awareness in Zimbabwean polytechnics
Get PDFThe heightened competition for skilled students, capable staff, and government funding has spurred Zimbabwean higher education institutions to engage in competitive efforts. Due to the intense competition in the higher education sector, higher education institutions have become more market-oriented than before. Furthermore, the increased offering of online programmes by higher education institutions during the COVID-19 pandemic period has increased the bargaining power of students. Higher education institutions have therefore taken initiatives to promote their institutions through various interactive digital marketing activities. Digital marketing activities have brought about innovative changes and opportunities for higher education marketers. Higher education marketers, specifically university marketers, are taking advantage of the opportunity to market their institutions through digital marketing activities, thereby gaining a competitive advantage over other institutions of higher education such as polytechnics. There is, therefore, a need for polytechnics to effectively utilise digital marketing activities such as websites, text messaging, social media marketing and email marketing for brand awareness purposes so that they gain a competitive advantage over other institutions of higher learning. The study aimed to empirically evaluate the influence of digital marketing activities on brand awareness of Zimbabwe polytechnics and to propose a model that can be adopted by Zimbabwean polytechnics in an attempt to enhance their brand awareness. As such, a conceptual model was constructed from the literature review to investigate the relationship between digital marketing activities (independent variable) and brand awareness (dependent variable). Based on the comprehensive literature review, four digital marketing activities (website, text messaging, social media marketing and email marketing) were identified in the Zimbabwean polytechnic context. The study further identified the digital marketing activities sub-factors that were adopted in the development of a customised measuring instrument that was used to evaluate the influence of digital marketing activities on brand awareness of Zimbabwean polytechnics. These sub-factors included web design, navigation, interactivity and relevance for website; personalisation, interactivity, timeliness and reliability for text messaging; interactivity, sharing of content, advocacy and credibility for social media marketing and personalisation, interest, informativeness, interactivity and efficiency for email marketing. Furthermore, five hypotheses were formulated and three hypotheses were supported while two hypotheses were rejected. The positivist paradigm, the descriptive research design and the quantitative approach were used in the current study. The study‟s target population consisted of the registered student population of the two Zimbabwean polytechnics in the Midlands province, in the Applied Sciences, Commerce and Engineering divisions. The respondents were selected using non-probability sampling, specifically convenience sampling. Data was collected through an email survey, whereby a web-based self-administered questionnaire was distributed to the Applied Sciences, Commerce and Engineering students with assistance from the Information Technology Departments of the two polytechnics. The measuring instrument consisted of three sections with section A having nominal scales to gather demographic data from respondents. Section B consisted of scaled items that measured the influence of digital marketing activities, while section C measured brand awareness focussing on the three levels of brand awareness. A total of 500 completed questionnaires were received from the two polytechnics. Out of the 500 completed questionnaires, a total of 492 questionnaires had usable responses. Therefore, the current study had a response rate of 98.4%. The study further used descriptive statistics and inferential statistics to interpret the data. The descriptive statistics utilised included frequency measures of central tendency and measures of dispersion or variation. Regarding inferential statistics, the study utilised the CFA, Pearson‟s correlation coefficient, regression analysis, p-value independent sample t-test, ANOVAs and the Welch Robust test, Tukey HSD test, the Games-Howell test and the Cohen‟s d tests. The findings of the study revealed a significant relationship and a strong correlation between digital marketing activities and brand awareness. Regarding website use and brand awareness, a significant relationship and a moderate correlation were determined. The results further revealed an insignificant relationship but a moderate correlation between text messaging and brand awareness. The empirical results also revealed a significant relationship and a strong correlation between social media marketing and brand awareness. Finally, an insignificant relationship and a moderate correlation were revealed between email marketing and brand awareness in the current study. Based on the empirical results, this study gave recommendations to polytechnic marketers. Under the website use items, the study revealed that the respondents had a less positive experience with the web design of the polytechnics' websites. It was recommended that polytechnic marketers should take pragmatic steps to enhance their polytechnic web designs so that students can take note of the college information on well-organised polytechnic websites. The study also found that the respondents felt the need to experience more personalisation and timeliness of the polytechnics' text messaging. Therefore the polytechnic marketers were advised to personalise their text messages each time that they send them to students enabling them to build long-lasting relationships with students. Regarding the timeliness of text messaging, the polytechnic marketers were advised to send text messages to students at the right time when they need the information so that the disseminated information is readily accepted by the students. The polytechnic marketers were also advised to provide up-to-date polytechnic information on their social media pages after the respondents indicated the need to experience more sharing of content on the colleges' social media pages through the provision of up-to-date information. Lastly, the empirical results revealed that the respondents felt the need to experience more personalisation and the provision of interesting content through polytechnic email marketing. Therefore the Zimbabwean polytechnic marketers were strongly recommended to personalise the students' emails to motivate students to engage with them personally. The polytechnic marketers were further recommended to include interesting content in students' emails so that they draw the students' attention to polytechnic information in their emails. The study made the following important contributions. Firstly, the study made contributions to theory, literature, knowledge, society and marketing practitioners within the context of digital marketing activities and brand awareness in Zimbabwean polytechnics. Secondly, the current study provided the measuring instrument and a model that adds to scholarly work and provides a basis for future research in the marketing of Zimbabwean polytechnics. Thirdly, the study will assist in the enhancement of brand awareness of Zimbabwean polytechnics, enabling them to attract academically gifted students who will become productive workers, self-reliant entrepreneurs and responsible citizens. Lastly, the model will also provide a basis for future reference for polytechnic marketers in their marketing efforts for competitive advantage purposes. The current study had limitations that comprised uneven sample distribution, the adoption of limited social media variables and the exclusion of external stakeholders from the current study. Finally, the study made recommendations for future areas of study.Thesis (PhD) -- Faculty of Business and Economic Sciences, School of Management Sciences, 202
Management strategies for reducing pathogens to improve project delivery in Thembisile Hani local municipality
Get PDFThis study focused on exploring management strategies that can be used to reduce pathogens in order to improve project delivery in Thembisile Hani Local Municipality (THLM). The main motivation behind this study is to identify the critical role that is played by municipalities in ensuring effective and efficient service delivery in the country. Municipalities are tasked with implementing service delivery and developmental projects in their communities with the aim of enhancing the quality of life of residents and contributing to economic development. However, the implementation of such projects often faces several obstacles which result in delays in their completion, ultimately incurring higher costs than initially budgeted for. The study sought to achieve the following objectives: to determine how people’s deliberate practices delay project delivery; to determine how project situations such as scope changes delay project delivery; to determine how the nature of task such as approvals by the client delay project delivery; to determine how THLM organisational structure or operations stall the smooth delivery of projects; and to recommend management strategies that will reduce pathogens and improve project delivery in THLM. The study was conducted using the quantitative approach, with a survey questionnaire being used to collect primary data from a sample of 78 employees from the municipalities. The sample was selected using the stratified sampling technique. The study found that there are a number of challenges that result in delays in the delivery of infrastructure projects in THLM. These include supply chain and procurement management challenges, lack of senior management support, lack of skills and competencies, changes in the scope of projects during implementation, delays in project approval, poor planning, and ineffective communication. The study recommended that THLM should enhance the skills of employees in the organisation to ensure that they have the right knowledge and skills that are required to implement infrastructure projects effectively. In addition, the project design stage should be carried out thoroughly to ensure that each project has a clearly defined scope. Furthermore, it is critical for the municipality to improve project planning and communication. Proper planning of projects ensures that the correct scope, schedule, and critical paths are developed, which ensures the smooth running of the project. Finally, management should improve supply chain and procurement management practices in the organisation as they are critical for the success of project delivery. Some limitations of this study relate to the focus on one municipality only as well as the use of only one method of data collection. iv Further research can be conducted on the same topic, focusing on a number of municipalities in the province in order to obtain better understanding of municipal project management and the overall challenges that affect project delivery in the organisations. The study can adopt a mixed-methods approach in order to obtain in-depth understanding of the research problem.Thesis (MSc) -- Faculty of Engineering, Built Environment and Technology, 202
