- Description: The current status quo is that African learners’ local indigenous knowledge (IK) and experiences from home (cultural heritage) are not considered in science classrooms. In the context of Namibia, it seems that the Namibian curriculum policies do little or nothing to decolonise and address the issues of equity and social injustice in Namibian schools. For instance, although the Namibian National Curriculum for Basic Education (NCBE) claims that it “embraces traditional knowledge”, it does not specify how this should be done in schools. As a result, little or no integration of IK is enacted in many of our schools in Namibia. Resultantly, learners seem to find science inaccessible and irrelevant to their everyday lives. It is against this background that in this study I sought to explore how the mobilisation of the indigenous technology of oil extraction (okuyenga) from marula nuts and melon seeds influences (or not) Grade 10 Biology learners’ conceptions, dispositions and sense making of the topic of enzymes. The study was located within the interpretive and indigenous research paradigms. Central to the interpretive paradigm is the development of a greater understanding of how people make sense of the contexts in which they live and work. On the other hand, central to indigenous research paradigms are belief systems based on the lived experiences, values, and histories of the participants. The Ubuntu perspective or approach in which respect and humble togetherness is emphasised is critical in indigenous research paradigms especially when researchers are working with and in communities as I did in this study. The study was conducted in an under resourced school in Walvis Bay, Namibia. A qualitative case study approach was used and data were derived from a focus group interview, participatory classroom observations, learners’ reflections, and a stimulated recall interview. Vygotsky’s socio-cultural theory was employed as a theoretical framework. Within the socio-cultural theory, mediation of learning, social interactions, and the zone of proximal development (ZPD) were used as analytical lenses. The conceptual framework comprised of perspectives (conceptions, dispositions) and sense making of enzymes by the learners. Criteria were also adapted from Atallah, Bryant, and Dada to analyse learners’ perspectives. A thematic approach to analysis was employed to come up with categories and sub-themes and thereafter, common sub-themes were combined to form themes. The findings of the study revealed that the presentations on the indigenous technology of oil extraction by the expert community members influenced learners’ conceptions, dispositions, and sense making of enzymes and other associated science concepts. This was noticed when learners extracted emerging science concepts from the indigenous technology of oil extraction. The implication of this study is that there is a need for science teachers to consider learners’ cultural heritage and integrate local IK in their Biology classrooms in order to make science accessible and relevant to learners. Moreover, the integration of local IK is critical for learners to embrace and respect their cultural heritage. This study thus recommends that teachers should make efforts to collaborate with expert community members who are the custodians of local IK and tap into their cultural heritage and wisdom to enrich teaching in their science classrooms. , Thesis (MEd) -- Faculty of Education, Education, 2021

- Description: This thesis analyses the working and living conditions of seasonal workers. In the context of increased demand for processed and higher-value food products, the agro-processing industry has been identified as a main contributor in the South African labour market (Department of Agriculture, Forestry and Fisheries, 2012: 17). In an effort to achieve high production outputs while saving on operational costs, employers have been seen incorporating more non-standard labour. In the agro-processing industry, non-standard labour has been in the form of seasonal workers which has been a matter of concern to state structures tasked with ensuring company compliance with labour regulations, especially as it relates to the protection of workers within the industry. Many of these workers are offered little protection, sub-standard working conditions, irregular working hours, having little or no benefits, lacking skills and often facing a lack of trade union representation (Fourie, 2008:111). The introduction of section 198B of Labour Relations Act (LRA) has been designed to address the rights of non-standard workers and to provide protection against exploitative practices within various industries (Griessel, 2015:1). The thesis focuses its attention on the role of social reproduction and the labour process in perpetuating domination and inequalities within the workplace. Further, the thesis examines the challenges of non-standard labour and the difficulties of regulating it in practice. It also discusses the livelihood strategies adopted by seasonal workers when not employed, in this case, by Carara Agro Processing Services. The research adopted qualitative research techniques in the form of semi-structured interviews and used purposive and snowball sampling in accessing relevant data for analysis purposes. , Thesis (MA) -- Faculty of Humanities, Sociology, 2021

- Description: Since the twentieth century, protected areas, usually in the form of nature reserves or national parks, have become increasingly more dominant as an international conservation strategy. An important factor in protected area management is the relationship between protected areas and its surrounding communities. Historically, the fortress conservation model based on the exclusion of human use and occupation prevailed in relation to protected areas. It is known that this approach brought with it many social and environmental injustices to local communities living in or adjacent to parks. However, a shift in conservation thinking occurred towards the end of the twentieth century, where it has increasingly been advocated for a more participatory approach in protected area management. South Africa has signed the international Convention on Biological Diversity that promotes a participatory approach to nature conservation, which is also reflected in the country’s national laws and policies. In relation to the literature and the lens of political ecology, this thesis sets out to assess in what ways and to what extent the participatory approach has been embraced by South Africa’s conservation authorities. As a case study, it looks at the Tsitsikamma National P ark ( incorporated into the larger Garden Route National Park). In order to get insight on h ow the participatory approach plays itself out at the T NP and what the nature of local communities’ relationship with the park is, this study looks at the aspects of (1) local communities’ socio-economic conditions, (2) their relationship with their natural environment, (3) their perception of nature conservation and (4) their perception of tourism. Then, taking all these aspects into account, (5) how local communities, in general, perceive their relationship with the p ark and its authorities. This study looked at the communities of Kurland, Nature’s Valley, Covie and Storms River. It shows in concurrence with other studies, that despite progressive laws and policies that express the intention of the South African state and SANParks to embrace the participatory approach, its implementation o n t he g round is riddled with challenges. , Thesis (MSocSc) -- Faculty of Humanities, Athropology, 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 researcher reviewed the factors that influence poor performance in matriculation examinations in the Libode District, also referred to as the OR Tambo Coastal District. Okoye (1982) defines poor academic performance of the individual or candidate in the learning situation as one in which a candidate fails to attain a set standard of performance in a given evaluation exercise such as a test, an examination or a series of continuous assessment. The research used a mixed method approach in an explanatory and case study research design. A purposive sampling of sixty (60) participants, who were the principals in the schools selected, was used. The researcher distributed forty-five (45) questionnaires and fifteen (15) interviews were conducted. The data analysis was done using Microsoft Excel for the quantitative data and thematic analysis for the qualitative data. Furthermore, inferential statistics were done, validating some statements in the research, and approving or disproving statements in the findings of the research. The perceptions of the causes of poor performance showed that forty percent (40 percent) of respondents disagreed that good planning was being done by the Department of Basic Education. Thirty-eight (38 percent ) percent of the participants also disagreed that low motivation on the part of the children was a factor in the poor results, followed by thirty-five percent (35 percent ) who slightly agreed that matric learners are failing because of socio-economic factors. Furthermore, on the challenges affecting the Department of Education, eight-seven percent (87 percent ) of the respondents supported the impact of drugs on poor performance, sixty-nine percent (69 percent) cited the issue of shortages of Learner Teaching and Support Material (LTSM) and sixty-five percent (65 percent) of respondents attributed the erratic and unfair progression of learners at grade eight (8), nine (9) and ten (10) level, which ultimately affected the grade twelve (12) results. The interview findings showed that the average pass rate was fifty percent (50 percent) in most schools, and the administration and leadership issues of the schools had been poorly managed. This, coupled with a shortage of LTSM and societal issues, such as drugs, negatively affected the matriculates. The research findings pointed to the challenge of drugs as being the biggest societal contributor to poor performance in matriculation results in OR Tambo Coastal District. The inferential statistics showed that gender could not affect the principal’s role as administrators and leader. However, gender did impact on leadership style. Women’s leadership style, which was more participative and consultative, was found to produce lower results; while male principals, who used a more bureaucratic, authoritative style, tended to produce higher results. Among other issues, the task-oriented, emotional nature of the principal’s job showed effects on school performance overall and the education level of the grade twelves (12), but educators alone could not affect the matric results. Furthermore, alone, the department’s efforts to improve results were not found to be productive; rather a number of factors could be combined to produce results. Lastly, the researcher recommended that the OR Tambo Coastal District should train teachers through development programmes, adjust the leadership style to one that is situational and transformational, and improve dialogue with school principals through regular school visits. Again, underperforming schools should be provided with LTSM, and teachers should be recruited and deployed on time. , Thesis (MPA) -- University of Fort Hare, 2021

Women’s leadership style, which was more participative and consultative, was found to produce lower results; while male principals, who used a more bureaucratic, authoritative style, tended to produce higher results. Among other issues, the task-oriented, emotional nature of the principal’s job showed effects on school performance overall and the education level of the grade twelves (12), but educators alone could not affect the matric results. Furthermore, alone, the department’s efforts to improve results were not found to be productive; rather a number of factors could be combined to produce results. Lastly, the researcher recommended that the OR Tambo Coastal District should train teachers through development programmes, adjust the leadership style to one that is situational and transformational, and improve dialogue with school principals through regular school visits. Again, underperforming schools should be provided with LTSM, and teachers should be recruited and deployed on time. , Thesis (MPA) -- University of Fort Hare, 2021

- Description: Buildings and houses are neglected by their owners/ government for different reasons, but money tends to be the leading reason in most instances. That then needs minds to work hand in hand; owners of the buildings must co-partner with the government to reduce the crisis by ensuring that there are no abandoned buildings in the community as these have proved to be breeding ground for criminal activities. The study was conducted in Libode town, which is under Nyandeni Local municipality in the Eastern Cape. Around Libode town there are abandoned buildings that have not been used for years. In most cases criminals use these for their criminal activities and hide outs from the law. There have been multiple cases reported about crimes committed inside and around these buildings, and still no intervention from the local government has been instituted. The aim of this study was to explore the influence of abandoned buildings on criminal activities in Libode Town. The study used a qualitative design in data collection and in describing the results. A sample of 8 key informants, 10 members from Qhankqu and 10 members from Belmond Township formed participants of the study. These were selected using the Snowball sampling method. In-depth / one on one interviews were used to collect data from key informants and focus group interviews were used to interview two groups, one from Belmond and the other from Qhankqu. Data were analysed and drafted using thematic analysis and transcription. Interviews were recorded and notes were taken to collect data. Findings indicate that indeed abandoned buildings are the source of so many criminal activities as it was explained by the researcher that youth hangs on these buildings and formulate gangs. These gangs are utilised by drug dealers to distribute their merchandise. Findings also explained that these buildings are located on places which are dangerous and it motivates wrongdoers to even carry on their doings. Findings indicated that lack of attention to these buildings by the government and the relevant owners was the main factor that led criminals to utilise abandoned buildings for their wrongdoings. Findings further showed that the government failed to ensure that these buildings are checked at least twice a month in order to keep control on these buildings, causing criminals to target the abandoned buildings. The study recommends that SAPS and Nyandeni local municipality draft Laws/ restrictions for the use of these buildings so that if anyone wants to use these buildings they must follow these laws and restrictions, which will help to restrict criminal elements from using these buildings without permission. To solve the problem of criminals taking advantage of abandoned buildings, the study recommends, the buildings should be either destroyed or fixed. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2020

- Description: The contemporary educational landscape in South Africa is characterised by prevailing inequities and disparities within higher education institutions and poor academic achievement. Although participation in higher education has increased over time, many students do not complete their courses within the required time and a high proportion of students continue to drop out, with few students progressing to postgraduate level. Majority of students who do not complete their courses are poor. Many students are faced with a number of barriers that stand in the way of academic success and, ultimately, graduation. However, through agency students often draw from a range of supports to promote their well-being and academic success. This study aims to balance the literature by investigating not only the barriers, but also the supports to success in university. This study addresses the notion that students from historically black universities are underrepresented in the literature. The current study explored Eastern Cape students’ barriers and supports to success within higher education. Five undergraduate female students participated in focus groups, which incorporated photovoice, adding to the participative nature of the research methodology. Focus group data were subjected to thematic analysis, informed by social constructionist theory. Three themes were prevalent: barriers within higher education, coping strategies positioned on a continuum and supports in higher education. Descriptions revealed that barriers and supports are reinforced by prevailing discourses, which are critiqued and/or used for the benefit of the students’ well-being. Barriers were limiting, yet also sites for personal growth and agency, whilst the engagement with supports was mediated predominantly by the intersection of social categories (race, gender, socio-economic status) occupied by students. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2020

- Description: The study aimed to evaluate the utilisation of game liver and maize meal as a partial fat replacer in the production of liver sausage. Mixed game livers (Blesbok, Impala and Springbok) were purchased and processed into sausages with varying levels of maize meal (6percent, 8percent, 10percent and 12percent). The liver sausages were cooked in a water bath for 2 hours to an internal temperate of 70 °C. Cooked sausages were cooled in ice water before storage at 4 °C before vacuum packed and frozen at -20 °C for 30 days. Proximate and fatty acid composition, pH, water activity, texture, lipid oxidation, and microbial content was determined on both day 0 and 30 days after frozen storage. Of the proximate composition, carbohydrate content had significant differences (P≤0.05) and increased as maize meal inclusion increased. The pH of raw game liver sausage batter differed (P≤0.05) between treatments. The pH of cooked game liver sausage differed (P≤0.05) from the raw batter. Textural parameters showed an increase (P<0.01) for both hardness and chewiness after 30 days of frozen storage. A positive correlation was found between hardness and chewiness with an increase in maize meal inclusion. TBARS values of the 12percent treatment differed (P≤0.05) from the maize meal inclusion treatments, but no differences (P>0.05) were recorded over 30 days of frozen storage. No differences (P>0.05) were recorded for the fatty acid composition between treatments. No growth was observed for microbial quality indicators nor Campylobacter spp. for all treatments. This study showed that frozen storage only had a negative effect on some textural parameters, while the inclusion of maize meal affects most physicochemical characteristics. , Thesis (MSc) -- Faculty of Science and Agriculture, 2020

- Description: Digital assessment, in particular tablet-based assessment, is on the rise and holds favourable prospects, especially for the rural South African context. However, the use of two-dimensional test items, such as pictures or patterns, has been found to lead to test bias in rural African settings, where such formats are unfamiliar. Little is known whether this would also be the case for two-dimensional tablet-based items. Therefore, this study investigated four and five-year-old rural isiXhosa-speaking children’s performance on two-dimensional tablet-based items compared with three-dimensional replicas of the tablet-based items. A total of sixty-three children were assessed and the data collected through the two test modes was statistically analysed according to the objectives of the study using the statistical package for the social science (SPSS). Descriptive statistics were employed by computing frequencies to determine the total sample’s performance on the two-dimensional tablet-based items as well as the three-dimensional items. Furthermore, a cross tabulation, followed by a chi-square analysis was done to examine the association between the children’s performance and the two test modes. The findings indicate a similar performance for the sample on both test formats with a slightly stronger performance by the sample on tablet-based items. More than just dimensionality was found to influence test performance in this study. Overall tablet-based assessment seems to be a promising tool for assessing children’s cognitive development in the rural South African context. , Thesis (MSoc Sci) (Psychology) -- University of Fort Hare, 2021

- Description: The adaptation and development of tablet-based measures are on the rise and hold promising prospects particularly for the rural South African context. However, limited research has been done on tablet-based assessment and whether it can be applied to the psychological assessment of the rural isiXhosa speaking children. For this reason the purpose of the study was to explore and describe how South African rural isiXhosa speaking children respond to a set of newly developed tablet-based items. By gathering information of this kind, the study hopes to inform and contribute to a larger national project concerned with the development of a tablet-based cognitive measure for isiXhosa speaking children. A multiple-case study design was utilized in a qualitative research paradigm. The data was collected amongst ten isiXhosa speaking children between the ages of 4 years and 5 years. The qualitative data was thematically analysed and Lincoln and Guba’s (1985) model for assessing the trustworthiness of qualitative data was applied. Findings indicate that tablet-based assessment holds promising prospects for the cognitive assessment of isiXhosa speaking children.

- Description: The objective of the current study was to evaluate the effects of feeding Dohne Merino rams with various inclusion levels of Fossil Shell Flour (FSF) as an additive supplement on feed preference and heat tolerance response of Dohne Merino rams. The FSF is used as an animal feed additive and is known to be rich in minerals. A total of twenty-four Dohne Merino rams (average 19.8 ± 0.43 kg body weight) were used to determine the feed preference of varying inclusion levels fossil shell flour (0g FSF/kg, 20g FSF/kg, 40g FSF/kg and 60g FSF/kg). The preference was assessed using feed intake and coefficient of preference. The feed intake, co-efficient of preference and physical attributes of feed (such as colour, smell and texture) was measured. The feed intake and coefficient of preference were higher in rams supplemented 60g FSF/kg (P < 0.05). The physical attributes of the experimental diets were adjudged based on the colour, smell and texture. The colour of experimental diets were brown in 0g FSF/kg while in 20g FSF/kg, 40g FSF/kg and 60g FSF/kg the colour of experimental diets were light brown (P< 0.05). All the experimental diets had a pleasant smell (P< 0.05). The texture of diets with 0g FSF/kg was moderately firm while diets 20g FSF/kg, 40g FSF/kg and 60g FSF/kg had a firm texture. The order of preference of diets supplemented with fossil shell flour in terms of feed intake by Dohne Merino rams was: 60g FSF/kg > 40g FSF/kg > 20gFSF/kg > 0g FSF/kg. In the second experiment, a total of twenty-four (n=24) Dohne Merino rams of about 8 to 9 months old, weighing 19.8 ± 0.43 kg were confined in individual pens for a period of 100 days. The rams were subjected to four varying inclusion levels of fossil shell flour (0g/kg, 20g/kg, 40g/kg and 60g/kg. Water and feed intake were recorded throughout the period of successive feeding. Blood samples were collected on days 0, 45 and 90. The parameters studied included the average daily water intake (ADWI), average feed intake (ADFI), skin temperature (ST), respiration rate (RR), pulse rate (PR), rectal temperature (RT), total plasma protein (TPP), mean corpuscular hemoglobin concentration (MCHC) and mean corpuscular volume (MCV). The inclusion levels of FSF affected both the ADWI and ADFI, showing a high-water intake and feed intake in rams subjected to 40g/kg of FSF followed by 60g FSF/kg, 20g FSF/kg and 0g FSF/kg (P< 0.01) respectively. All the physiological parameters ST, RT, RR, HR and PR decreased with an increase in the inclusion levels of FSF (P< 0.01). The TPP increased as the levels of FSF increases (P< 0.01). The MCHC was low in rams subjected to 60g FSF/kg and in 0g to 40g FSF/kg TPP increases as levels of FSF increases (P< 0.01). This study concluded that supplementing with various inclusion levels of FSF had a positive effect on feed preference. The FSF also showed the ability to mitigate heat stress in Dohne Merino rams. , Thesis (MSc) -- Faculty of Science and Agriculture, 2020

- Description: The study explored and described the perceptions and experiences of Primary Health Care facility managers regarding their leadership and management competencies in the Buffalo City Metro Health District in the Eastern Cape Province. The objectives of this study were to explore and describe the leadership competencies required for facility managers to exercise their leadership in Primary Health Care facilities and to bring about the recommendation. The population of this study comprised of facility managers who are appointed in facility management position permanently or on acting basis during the time of the study, in rural, urban, and semi-urban Primary Health Care facilities (clinics) in Buffalo City Health District. Non-probability convenience sampling was used to select the participants. Two focus group interviews with 10 participants per group were held to collect data. Thematic data analysis was used to analyze the data. The findings were discussed according to themes and subthemes. Four themes and 9 subthemes were identified from the data. Themes include departmental factors, individual factors, and political factors. The subthemes include managers lack of support, need for capacitation of staff, lack of uniformity in exercising leadership, work positions, infrastructure, staff shortages, lack of involvement in decision making, lack of resources, feeling of being a failure, not meeting expectation (workload) role of managers, pressure, the resistance of staff members to change, absenteeism, teamwork, compliance to policies, the 80/20 principle, nurse-patient ratio, and consultation. The trustworthiness of the findings was ensured by focussing on dependability, confirmability, transferability, and credibility. The study concluded that facility managers receive very limited supervision to perform their management duties in their facilities. They also need adequate resources, induction, training and a habitable work environment to ensure that quality care is provided. The study recommended that the Department of Health should have a program for supervision, mentorship, and guiding the facility managers in the Primary Health Care facilities. It should also establish a training and development program on leadership, finance management and technology. Lastly, there should be more accountability by facility managers at the different departmental levels i.e. national, province, district subdistrict, and other internal and external stakeholders. , Thesis (MPH) -- Faculty of Health Sciences, 2020

- Description: The study explored and described the perceptions and experiences of Primary Health Care facility managers regarding their leadership and management competencies in the Buffalo City Metro Health District in the Eastern Cape Province. The objectives of this study were to explore and describe the leadership competencies required for facility managers to exercise their leadership in Primary Health Care facilities and to bring about the recommendation. The population of this study comprised of facility managers who are appointed in facility management position permanently or on acting basis during the time of the study, in rural, urban, and semi-urban Primary Health Care facilities (clinics) in Buffalo City Health District. Non-probability convenience sampling was used to select the participants. Two focus group interviews with 10 participants per group were held to collect data. Thematic data analysis was used to analyze the data. The findings were discussed according to themes and subthemes. Four themes and 9 subthemes were identified from the data. Themes include departmental factors, individual factors, and political factors. The subthemes include managers lack of support, need for capacitation of staff, lack of uniformity in exercising leadership, work positions, infrastructure, staff shortages, lack of involvement in decision making, lack of resources, feeling of being a failure, not meeting expectation (workload) role of managers, pressure, the resistance of staff members to change, absenteeism, teamwork, compliance to policies, the 80/20 principle, nurse-patient ratio, and consultation. The trustworthiness of the findings was ensured by focussing on dependability, confirmability, transferability, and credibility. The study concluded that facility managers receive very limited supervision to perform their management duties in their facilities. They also need adequate resources, induction, training and a habitable work environment to ensure that quality care is provided. The study recommended that the Department of Health should have a program for supervision, mentorship, and guiding the facility managers in the Primary Health Care facilities. It should also establish a training and development program on leadership, finance management and technology. Lastly, there should be more accountability by facility managers at the different departmental levels i.e. national, province, district subdistrict, and other internal and external stakeholders. , Thesis (MPH) -- Faculty of Health Sciences, 2020

- Description: School managers have always been on the forefront of the administration of education system since they are the active agents who lead their schools towards wider goals of improving access and quality of education. The contemporary world has had a great deal of surmounting pressure from globalisation and other forces of a universalised society. These influences have become more and more pronounced with the inevitable influences of digitalisation and in the fourth industrial revolution. Information and Communication Technologies have transformed how things are done even within the settings of schools. Attempting to ignore this bold revolution for the so-called ‘tried and tested’ conventional methods of school management, assessment, learning, teaching and monitoring does not only leave a school or education system behind but inhibits leaners and stakeholders from enjoying the many benefits of innovation, creativity and flexibility. This study explores the role of school managers in creating and maintaining an innovative culture and academic performance in selected public schools of the Cofimvaba Education District which has become synonymous with declining pass rates post-1994. A qualitative research approach was used where existing literature collected, collated and thematically analysed. The findings of the study indicated that the school principals are not empowered or willing enough to catalyse the creation and sustaining of innovative cultures in schools. There was also a political willingness of the leaders of the education sector in the Cofimvaba Education District is deficient, the absence of sanctions for failure to innovate is a challenge to innovation. Other findings include evidence policy gaps on what is innovation and who must do what in schools which affects the efficacy of school managers. The study also established that the bureaucratisation of the education sector has done nothing by crippled school managers’ ability to innovate by school managers. The study recommends strategies on how school managers can become that active catalyst that they should be, to drive innovation include in-service training and setting minimum benchmarks for school managers eligibility. Also, policy interventions such as 4th industrial revolution aligned innovation regulations, exchange of ideas with countries which successful school innovation formulating a sanction model of non-performers, towards improving access and quality of education in the Cofimvaba Education District. , Thesis (PhD) -- Faculty of Management and Commerce, 2020

- Description: Developing countries, especially those in the Sub-Saharan African region are still marked with high and increasing rate of unemployment. To counter this, countries in the African countries introduced the Special Economic Zones programme in the 1970s which proliferated during the 1990s to date. However, there is scant academic literature on the role of SEZs’ contribution to job creation. Against this background, this study investigated the contribution of the SEZs to job creation in the SSA region in general and South Africa in particular. A mixed method approach was used wherein the qualitative data focused on the South Africa and the quantitative data focused on SSA in general. In-depth interviews with key informants in four operational SEZs and DTI in South Africa were complimented with document reviews and direct observation. Inductive thematic analysis was also used to analyse qualitative data, while the Panel Corrected Standard Errors was used to analyse the qualitative data. The results show that SEZs have made a positive contribution to job creation in South Africa. This contribution is constrained, inter alia, by stringent visa regulations, an ineffective one-stop-shop model, reliance on government funding and the lag between the signing and operation of investments. Nevertheless, incentives and support services seem to counteract some of these challenges. Similarly, the SEZs have a positive contribution to job creation in SSA. However, this impact has been largely insignificant. , Thesis (MCom) -- Faculty of Management and Commerce, 2020

- Description: The main objective of the study was to investigate the determinants of the currency deposit ratio of South Africa. The stability of the demand for money has been a recurring area of interest of empirical research on the South African economy. Underlying this interest in the behavior of money demand is the potential role of movement in monetary aggregates as indicators of future developments in inflation. Specifically, if a stable relationship exists between the demand for money and its determinants, changes in the money supply can provide useful information in the longer terms. While there has been considerable empirical research on estimating the money demand function for many less developed countries (LDCs), the currency demand function has been largely ignored. The study used secondary data sourced from the South African Reserve Bank, Statistics South Africa and Quantec. It also used annual data from 2000 to 2018 with an autoregressive distributed lag (ARDL) technique used for regression purposes. The study opted for this model because the variables were a mixture of me (0) and me (1). The empirical results show that income had a positive relationship with currency deposit ratio. In other words, when income increases, the amount of currency in circulation increases relative to deposits. Results show that there is a negative relationship between inflation and currency demand ratio. The SARB has to monitor changes in income in order to keep pace with the demand for cash. They must also use other monetary policy operational variables such as M3 to ensure that there is a match between income and money demand and money supply. , Thesis (MCom) -- Faculty of Management and Commerce, 2020

- Description: Ecological data on the development and distribution of mangroves over time suggest that mangroves were strictly tropical in nature but have extended to higher latitudes during warmer periods. Species distribution models show that the mangrove range may have since 1963 expand by 17 km in 2020 and by as much as 68 km southwards by 2050. More climate data obtained, and modelling of future climate have increased interest in the thermal tolerance or organisms. Critical thermal maxima (CTMax) and thermal tolerance were employed to determine the thermal limits of common estuarine species associated with the mangrove forests at Mngazana Estuary. Three species were selected, each representing a medium within the mangrove environment: for water, i) Palaemon peringueyi; ii) for air, Cerithidea decollata; and iii) Parasesarma catenatum on the substratum. Animals were acclimated for 48 hrs following the thermal history of the environment. Each individual was exposed to constant rate of water temperature increase of 1°C.h-1. Different size classes (adult, sub-adult, juveniles) of crabs were used to determine the CTMax performance. Parasesarma catenatum showed intraspecific variability in CTMax in both air and water. Palaemon Peringueyi had a CTMax value of 33.8°C±1.96 while C. decollata had a CTMax of 39.6°C±2.76 and P. catenatum had a CTMax of 36,38 ±1,57 in water and 34,1 ±1,67 in air. Different size classes (Adult, Sub-adult, Juveniles) of crabs were used to further determine their CTMax performance. Parasesarma catenatum showed of intraspecific variability in CTMax in both air and water. Juvenile crabs showed higher CTMax in water than in air, while adult and sub-adults showed a higher CTMax in air. The size classes of P. catenatum (Adult, Sub-adult, Juveniles) were exposed to a range of salinity treatments from 5-65 for both shock and acclimated exposures. For acclimated exposures, crabs were acclimated down/up at change of 5-10 untill the test salinity was reached, at which point the crabs were exposed. For the shock exposure, the crabs were directly exposed to the test salinity from the holding salinity of 35. This study shows P. catenatum is euryhaline, tolerating salinities been 10 and 50. Survival was highest across all cohorts for the short-term (shock) exposure, suggesting prolonged exposure to hypo/hypersaline conditions may be detrimental for this keystone Mngazana Estuary species. Juven.ile populations showed the highest survival rate for both shock and acclimated exposure. This study highlights the importance of microhabitat variability and its effect on the tolerance of different species to abiotic factors and so may be useful in modelling the effects of climate change in these systems. , Thesis (MSc) (Zoology) -- University of Fort Hare, 2021
