- Description: This study investigated the extent to which gays and lesbians access quality sexual and reproductive health (SRH) services in Pretoria and Bulawayo. The study also examines the facilitators and barriers for accessing the same services. Theoretically, the study was grounded in the Health Belief Model (Hochbaum, 1958, modified by Rosenstock, 1974 and Siddiqui, 2016). To answer the research questions, a mixed methods approach was applied involving both qualitative and quantitative data collection methods. A total of 30 key informant interviews, eight focus group discussions and 387 questionnaires were administered using purposive, time location and snowball sampling approaches in the two cities. The study found that the most commonly available sexual and reproductive health (SRH) services were contraceptive services, sexually transmitted infections (STI) services and Human immunodeficiency syndrome (HIV) services. The services were provided at public health facilities, drop-in centres and through outreach activities operated by Civil Society Organizations (CSOs). The least available services that gays and lesbians required as part of a comprehensive package were access to information, education and communications (IEC) materials and mental health and psychosocial support services (MHPSS). Several service providers were not adhering to the World Health Organization (WHO) guidelines for provision of comprehensive services for key populations including gays and lesbians. Critical gaps noted included the absence of key populations-only service hours, lack of options for clinicians to attend to them, presence of a stigma and discrimination free environment and provision of comprehensive package of services under one roof. Most of the referral facilities had limited drugs, equipment and supplies for cancer screening and they had no HIV prevention, sex change, in-vitro fertilization, and sterilization services and procedures. The quality of physical facilities and SRH services in both cities did not meet the expectations of gays and lesbians, acting as a barrier to their health seeking behaviour. Stigma and discrimination from healthcare workers was a huge barrier affecting access across all public health facilities. The acts of stigmatisation and discrimination affected the perceptions that gays and lesbians had regarding the quality of the services and compromised access of the same. In view of these health system challenges, the study recommends that there is need for public authorities in both cities to address the bottlenecks and barriers affecting access to SRH services and products such as lubricants, affordable quality condoms, dental dams and latex gloves while reinforcing the facilitating factors promoting access. Healthcare workers need further training on how to provide comprehensive services for gays and lesbians according to the WHO guidelines. Public health authorities in Bulawayo and Pretoria should build upon the identified factors which facilitated the access to SRH services and use of products such as condoms and lubricants. These factors require strengthening of community-based organizations and networks that work directly with gays and lesbians in both Bulawayo and Pretoria. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2021

- Description: Many developing countries, including South Africa, have identified the provision and implementation of strong science curricula as central to their developmental needs. Stoichiometry is a fundamental chemistry topic because the concepts involved form the basis of later topics such as chemical equilibrium, rates of reactions, redox reactions, and acid-base reactions. School students consistently demonstrate lack of understanding of stoichiometry-related concepts and skills such as the particulate nature of matter and related mathematical problem-solving. The poor performance of high school students in central science topics such as stoichiometry is problematic for their further study of chemistry and for the country meeting its need for science graduates. Successive examiner reports pointed to the lack of integration of stoichiometry concepts across the grades being the main problem. However, no study could be found which explores how stoichiometry is integrated in the South African Natural Sciences and Physical Sciences curriculum across the grades. This provided the rationale for the current study. The case study reported in this thesis thus aimed to explore integration of stoichiometry concepts in South African Natural Sciences and Physical Sciences school curricula. It involved document analysis as the method of collecting data. The research adopted the social realist paradigm, with its realist ontology and relativist epistemology. Legitimation Code Theory provided the theoretical framing. Chemistry concepts that are foundational to the understanding of stoichiometry according to literature, were chosen as root concepts for the concept mapping undertaken to identify types of integration. The concept maps revealed four stoichiometry integration themes: integration of stoichiometry concepts with symbols, integration of stoichiometry concepts with explanations, integration with applications in a chemistry context, and integration with an everyday context. These themes provided integration categories. A semantic gravity translation device was then developed for characterising the types of integration in terms of the degree of contextualisation. The results of this study show that stoichiometry integration of weaker semantic gravity is legitimated more strongly over other semantic gravity codes in the Natural Sciences and Physical Sciences curricula across all grade levels. While this has advantages in terms of knowledge-building potential, the consequence is that the integration occurs at very abstract levels that are far removed from learners’ everyday lives. The practical implication for curriculum developers involves increasing the instances of integration of stoichiometry concepts at stronger levels of semantic gravity, for a more even semantic gravity range of integration types. Natural Sciences and Physical Sciences teachers also need to source and include real-life examples for explanations and applications of stoichiometry concepts when teaching, in light of current curriculum documents focusing more on abstract forms of integration. Methodologically, this study contributes to the increased utility of semantic gravity through its exploration of integration in relation to knowledge-building potential of curriculum for hierarchical knowledge structures such as chemistry. , Thesis (MEd) -- Faculty of Education, Education, 2022

- Description: This paper draws on two fields, human resources management and entrepreneurship to examine the observed problem of stalled established business ownership even despite favourable Total Early Stage entrepreneurship (TEA) among many nations. The aim of the study was to established the perceptions of entrepreneurs on the influence of human capital on the growth and sustainability of entrepreneurial ventures from the restaurant sector in Cape Town. The study adopted a qualitative research design which was based on interviews to infer the entrepreneurs’ perceptions on the role of effective human capital management to growth of entrepreneurial ventures. Fifteen interviews were conducted and analysed following a thematic analyse procedure. Various themes and sub themes which pointed to the critically of effective human capital management were established. It was found the people possess certain social, philosophical, psychological and ideological attributes that cannot be found from other resources. At the end of the analysis, it was established that human resources are central to the growth of entrepreneurial ventures as they possess certain exploitable entrepreneurial talents, are capable of unlocking the value of other resources and also they are the drivers of growth. Following these findings, it was recommended that entrepreneurs should centralise effective human capital management for growth.

- Description: Academic writing is a peculiar phenomenon – it varies greatly from discipline to discipline and its requirements are rarely made overt. Taking on the writing practices of the academy has implications for identity and it is thus unsurprising that it is seen to be a risky endeavour. This article analyses the experiences of postgraduate scholars who have participated in writing groups that meet weekly to read each other’s work and provide supportive critique. Thirty-two people provided detailed, anonymous evaluations of their writing groups and these were studied using a discourse analysis. Three main findings are discussed here. Firstly, writing circles allowed for academic writing development to be engaged with as a social practice, where the disciplinary norms could be made more explicit through peer deliberation, and where they could also be challenged. Secondly, the lack of hierarchical power in the writing groups was key to making safe spaces for agency development, and also for providing positive peer pressure whereby participants were spurred on to work on their writing. Thirdly, the fact that the groups were interdisciplinary, within cognate disciplinary families, provided an interesting challenge in that the students had to consider what these non-specialist readers would or would not understand. This process assisted students in clarifying their writing. Participants’ evaluation of the writing groups revealed an overall sense that these contributed to postgraduate student wellbeing and were places of significant agential development.

- Description: The nonlinear absorption and optical limiting (OL) performance of tetra- and octasubstituted zinc phthalocyanine complexes were described in solution and in the solid state using the open-aperture Z-scan technique. The measurements were performed using collimated 4 ns pulses generated from a frequency-doubled Nd:YAG laser at 532 nm wavelength. The polymeric films exhibit a much larger effective nonlinear absorption coefficient in comparison with solution. However, the parameters of the ratio of the excited to ground state absorption cross section and energy-dependent saturation in solution are much better compared to properties in the polymeric film. In terms of the ratio of the excited to ground state absorption cross section, the peripherally substituted complexes show better OL performance than the non-peripherally substituted derivative.

- Description: Studies on the relationship between funding and efficiency of public universities in South Africa were triggered mainly by the decline of government spending on public universities while the enrolment of financially needy students is increasing. This increase is a product of government’s initiatives to redress the imbalances in access and success caused by the apartheid regime. However, the government seems to be grappling to strike a balance between its initiatives and funding. While the government’s HE transformation initiatives are appreciated, public universities are caught in a dilemma: their revenue is no longer sufficient for the operations given the increase in the number of unfunded and financially constrained students. It is with this background that the study evaluates the efficiency of public South African universities for the period 2009–2016 and how funding composition affects their efficiency. The study contributes to the existing literature in various ways First, a recent study on this subject matter found a decline in the average technical efficiency (TE) score of the South African public universities from 83percent in 2009 to 78percent in 2013. However, the study did not include non-academic staff among other input variables that are assumed to potentially influence performance outcomes of the universities. We therefore developed an argument that a biased conclusion on the subject matter is likely, if academic staff are assumed to dominate efficiency of public universities in South Africa while the efforts of non-academic staff are not considered. Using a Data Envelopment Analysis (DEA) model, the findings of this study revealed that over the study period the average TE of public universities in South Africa increased from 91percent to 95percent. These results suggest that academic and non-academic staff can be deemed as mutually inclusive variables and therefore neglecting either of them can lead to biased estimated average TE scores. The efficiency levels provided in this study can be used as performance benchmarks for identifying potential improvements required to reach a satisfactory level of efficiency. Second, the literature argues that different streams of revenue utilised for funding universities’ activities can provide alternative incentives which might have an impact on efficiency. However, none of the studies examined comparatively the impact of different revenue streams on the efficiency of the public universities in South Africa. Using a fixed-effects regression model, this study found that only traditional universities’ efficiency can be affected by student fees and private income, while government funding does not seem to bear a significant impact on the efficiency of all universities irrespective of their category. Precisely, student fees enhance the efficiency of traditional universities while private income is deleterious on the efficiency of the traditional universities. The study concluded that traditional universities use students’ fees efficiently to deliver quality academic services in a bid to safeguard their reputation and image while revenue from private funders is not efficiently utilised due to the principal-agent problem. In terms of state funding, it was concluded that government spending on public universities is yet to reach a minimum threshold level at which it can contribute significantly to the efficiency of the universities. Third, recent literature used Stochastic Frontier Analysis (SFA) efficiency scores to determine the drivers of efficiency of public universities in South Africa. Although SFA can control for the stochastic error component in the econometric estimation, the model imposes several theoretical assumptions in the production function which may lead to biased estimations. As a result, several studies on efficiency analysis of Higher Education Institutions (HIEs) around the globe have reverted to using DEA. Using DEA efficiency scores and a Tobit model, this study found that that quality of staff, government funding, student fees, private income, and GDP per capita are positive factors of efficiency while the share of non-white to white staff was found as the determinant of inefficiency. It was concluded that adequate funding and proper management of income by the universities, economic growth and employment of highly educated academic staff can increase efficiency levels of public universities in South Africa, whereas an increase of non-white to white staff in South African public universities is a threat to the universities’ efficiency. Overall, the findings of this study suggest that a cost-sharing framework is inevitable in the South African higher education (HE) system, particularly now that the government is heavily burdened due to the prevailing economic turmoil in the country. As a results, private funders and parents and/guardians are encouraged to honour their portion of obligations with universities. Due to limited funding across all sources, efforts dedicated to strengthen managerial competencies of public universities in South Africa can eliminate the principle-agent problem and therefore promote managerial efficiency. The South African government is encouraged to support its transformation initiatives on HEIs with adequate funding, otherwise the initiatives need to be revisited and revised to suit the current economic environment. Revision of these initiatives may include adjustment of the education standards such that state funding can be allocated to deserving students in terms of both finances and students’ performance starting from matric. , Thesis (PhD) -- Faculty of Management and Commerce, 2020

- Description: Infection control and prevention is an issue that is of utmost importance to every health practitioner, including professional nurses, as patients who undergo surgeries could develop sepsis, leading to failure of multiple organs and possibly death. Surgical site infections acquired from operating theatres are often introduced when there is lack of application of and adherence to the necessary control measures, sterile principles and techniques, including the appropriate use of surgical attire. This study aimed to contextualize, implement and evaluate an existing educational intervention regarding the use of surgical attire in operating theatres, in order to establish whether the educational intervention enhanced the practices of professional nurses in operating theatres regarding the use of surgical attire. A quantitative research design, using a quasi-experimental two-group pre-test, post-test intervention approach was employed for the study. The study consisted of three phases. The study is underpinned by the Promoting Action on Research Implementation (PARiHS) framework. The research sample consisted of all professional nurses working in the public and private operating theatres in the Nelson Mandela Bay Municipality. Purposive sampling was used to select the hospitals in control (Hospitals 2 and 3) and intervention groups (Hospitals 4 and 5), ensuring an equal number of public and iv private hospitals in each group. Data was collected through self-administered pre- and post-questionnaires. An existing educational intervention based on the Association of Perioperative Registered Nurses (AORN’s) guidelines was contextualized through review by three professional nurses with a specialty in operating theatre. The educational intervention was implemented for the intervention group, while the control group only received the summary of the AORN guidelines. Reliability and validity were ensured through the conduct of a pilot study, and expert review by three professional nurses with a specialty in operating theatre in order to check the validity and reliability of the data collection instrument and educational intervention. This means that the educational intervention had a positive effect in terms of improving the professional nurses’ practices on the use of surgical attire to prevent surgical site infections in operating theatres. , Thesis (MA) -- Faculty of Health Sciences Clinical Care and Medicinal Science, 2020

- Description: To investigate the potential anti-diabetic/obesity properties of oral cannabis administration in an obese and streptozotocin (STZ)-induced diabetic rat model, as well as an obese rat model, and to determine the mechanism of action, with a focus on the peritoneal and intramuscular fat depots. Experimental Design: Obese and STZ-induced diabetic rats were allocated a high fat diet (HFD) and intraperitoneally injected with STZ to mimic an obese and diabetic state. The rats were then orally administered cannabis extract (CE) of 1.25, 2.5 and 5.0 mg/kg body weight (relative to tetrahydrocannabinol (THC) content) or metformin as a positive control. For the obese rat model, the rats were allocated either a high carbohydrate diet (HCD) or high fat diet (HFD) and orally administered with cannabis extract of 1.25 mg/kg body weight (relative to THC content). Weight, blood and insulin-resistant parameters of the rats were monitored. The mitochondrial to genomic DNA ratio (MT:18S DNA), average adipocyte area of the various adipose tissues, citrate synthase and carnitine palmitoyltransferase 1 (CPT1) enzyme activities of the peritoneal and intramuscular fat were measured. Gene expression levels of uncoupling protein 1 (UCP1), cell-death inducing DNA fragmentation factor alpha like effector-a (Cidea), perilipin, hormone-sensitive lipase (HSL) and mitochondrial transcription factor A (TFAM) were measured in peritoneal fat, intramuscular fat and brown adipose tissue (BAT). Main Findings: Obese and STZ-induced diabetic rat model: Due to the biphasic nature of cannabinoids, cannabis dosage plays an important role in the observed effects. CE1.25 was the only cannabis treatment effective in improving the insulinresistant parameters of the rats unlike the other higher cannabis concentrations (CE2.5 and CE5.0). In the peritoneal fat, CE1.25 increased MT:18S DNA, increased citrate synthase activity, and decreased the average adipocyte area when compared to the STZ group. CE1.25 also induced fat beigeing by upregulating gene expression levels of UCP1 and Cidea. XIX Furthermore, an increase in gene expression levels of perilipin, HSL, and TFAM showed increased fat mobilization and metabolic activity. In the intramuscular fat, CE1.25 also reduced the average adipocytes area. However, a different mechanism of action was observed where CE1.25 did not induce fat beigeing, but instead increased both citrate synthase and CPT1 enzyme activities and gene expression levels of HSL, thereby indicating increased fat oxidation and mitochondrial activity. , Thesis (PhD) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2023

- Description: Crop loss and failure can impact both a country’s economy and food security, often to devastating effects. As such, the importance of successfully detecting plant stresses early in their development is essential to minimize spread and damage to crop production. Identification of the stress and the stress-causing agent is the most critical and challenging step in plant and crop protection. With the development of and increase in ease of access to new equipment and technology in recent years, the use of spectroscopy in the early detection of plant diseases has become notably popular. This thesis narrows down the most suitable multispectral imaging techniques and machine learning algorithms for early stress detection. Datasets were collected of visible images and multispectral images. Dehydration was selected as the plant stress type for the main experiments, and data was collected from six plant species typically used in agriculture. Key contributions of this thesis include multispectral and visible datasets showing plant dehydration as well as a separate preliminary dataset on plant disease. Promising results on dehydration showed statistically significant accuracy improvements in the multispectral imaging compared to visible imaging for early stress detection, with multispectral input obtaining a 92.50% accuracy over visible input’s 77.50% on general plant species. The system was effective at stress detection on known plant species, with multispectral imaging introducing greater improvement to early stress detection than advanced stress detection. Furthermore, strong species discrimination was achieved when exclusively testing either early or advanced dehydration against healthy species. , Thesis (MSc) -- Faculty of Science, Ichthyology & Fisheries Sciences, 2022

- Description: The synthesis of ball–type indium phthalocyanine (complex 4) and its covalent attachment to glutathione (GSH–) capped (Ag, Au, CdTeSe, CdTeSe/ZnO) nanoparticles are reported in this work. Furthermore, their photophysical and nonlinear optical behaviour were investigated. We observed a decrease in the fluorescence quantum yield with corresponding increase in the triplet quantum yield of the nanoconjugates in comparison to complex 4 alone. The reverse saturable absorption was found to be dependent on excited state absorption. The optical limiting threshold ranges from 0.40–0.78 (J/cm2). The nanoconjugate of the complex 4 with GSH–CdTeSe/ZnO (QD1) accounted for the most improved triplet state parameters and nonlinear optical behaviour in comparison to complex 4 and the other nanoconjugates studied in this work.

- Description: Midwives are largely responsible for maternity care in hospitals. As such, they play a significant role in ensuring the health and well-being of pregnant women and newborn babies. To perform that duty effectively, midwives need to be professional in their conduct. However, there are reports that midwives have displayed poor attitudes and behaviour in South Africa. The main research question was “what are the perceptions of patients about attitudes and behaviours of midwives in the maternity section in a public hospital in East London, South Africa?” The aim of the study was to explore the reasons behind poor attitudes and behaviour of midwives in midwifery practice and suggest interventions that can be introduced to promote professional attitudes and behaviour by midwives in a public hospital in East London. This study used a qualitative approach to collect data. The research instrument that was used for this study was semi-structured interviews. The sample of 20 participants which was purposively selected consisted of women that have used the East London public hospital maternity section. Data was collected using coding and themes emanating from the data generated. Midwives are valued and play a very significant role in providing maternal care. Be that as it may, midwives exhibit poor attitudes and behaviours such as being rude, lack sympathy, and lack of empathy. On the other hand, midwives act professionally and are supportive of patients. There is, therefore, a need for the provision of professional etiquette training services, stress counseling, use of work development strategies and performance management systems, technical training, linkage system of traditional and modern midwives, and the use of internet platforms to increase interaction between midwives and those that need maternity care services. , Thesis (MPA) -- Faculty of Health Sciences, 2019

- Description: Rural inhabitants make considerable use of wild resources from communal areas around their settlements, as well as from arable and residential plots. These wild resources compete with the main crops planted in arable plots and home gardens, but play a significant economic and nutritional role in rural livelihoods. This paper reports upon a conservative financial evaluation of the wild plant resources harvested from home gardens and arable plots by inhabitants of rural village in the Bushbuckridge lowveld (South Africa), and examines their importance relative to other domesticated crops. On average, each household made use of four to five species of wild plants growing on their residential plot, whereas the mean number of crop plants was 3.4. The total value of all plants was R1694 (US$ 269) per household per year, or approximately R4200 (US$ 667) per hectare of home garden per year. Wild plants represented 31% of the value of all plants grown on residential plots, relative to the 69% for domesticated crops (including fruit trees). Approximately 72% of the total value of all plant products was consumed by the household, and the remaining 28% was sold.

- Description: A water-soluble zinc phthalocyanine (ZnPc) complex with four negatively charged electron-withdrawing sulfonic acid substituents at the nonperipheral positions (α-ZnTSPc) is found to have a high singlet oxygen (1O2) quantum yield and exhibits high photostability. The formation of aggregates is hindered and the highest occupied molecular orbital is significantly stabilized, making α-ZnTSPc potentially suitable for its use as a photosensitizer for photodynamic therapy and photoimmunotherapy. Atomic force microscopy (AFM) reveals that mixtures of the negatively charged α-ZnTSPc complex with a similar positively charged ZnPc were found to result in the self-assembly of one-dimensional accordion-like fibers. Supramolecular fibers can be formed in aqueous solutions through intermolecular electrostatic and donor–acceptor interactions between the two water-soluble ZnPcs.

- Description: (Prologue) I could only see in black and white as if I had travelled through time. I was the star of the medieval people who waited on me. The city was Johannesburg where strange faces called me a traitor because I was an educated black person. I hid between the skyscrapers and ran into a mirror image of myself as a man. “I write this book,” he said to his readers, “To invoke a yearning in our youth to awaken from slumber. To set examples for them to desist from characters like Velesazi and Nongendi, and imitate Nomsa and Themba. And also, to contribute to Xhosa literature.” He signed off by calling himself our servant. These are the words from the note my great-grandfather left me. We walked together across a barren field and past a graveyard. I was feeling tired and lost; I wanted to get home as fast as possible. We quickened our step and entered a church site. Inside the church were all my close relatives. I saw myself on stage looking down at them, and when I opened my mouth to sing, they began laughing at me. I imagined him in his 1917 suit, as a writer, penning down his first novel that is dedicated to his mother. His round cheeks enveloped in a haze of candle light. He visited my dream in 2012 and in the dream he asked me, “Do you see?” I said, “Yes, I see.” My great-grandfather hummed a song from his belly. I inhaled deeply into my belly and then exhaled a sound. Together we hummed this song that made everyone fall silent and listen. In the dream I could feel my lungs expanding and deflating along to the rhythm of the song. As my great-grandfather and I sang it, the night lamps shone brighter. I had become my great-grandfather, wearing his suit and black leather shoes. His friends were my friends. They turned and asked me what my clan name was. When I told them, they whispered something among themselves. One of them said to me, “Unogcwabevu.” I saw a white unknown woman who was afraid of me. I told her it is going to be okay, and that I would not harm her. But the colour of my skin frightened her. , Thesis (MA) -- Faculty of Humanities, School of Languages and Literatures, 2022

When I told them, they whispered something among themselves. One of them said to me, “Unogcwabevu.” I saw a white unknown woman who was afraid of me. I told her it is going to be okay, and that I would not harm her. But the colour of my skin frightened her. , Thesis (MA) -- Faculty of Humanities, School of Languages and Literatures, 2022

- Description: This study was based on the relationship between the leadership styles of Academic head of Department and employee job satisfaction at the Higher Education Institution (HEI). In so doing, the study was based on the following questions: What is the relationship between leadership styles of HODs and employee job satisfaction in a Higher Education institution in the Eastern Cape Province of South Africa. A purposive sampling technique was utilised to select the participants, which comprised 80 academic staff members to which the researcher hand-delivered 80 questionnaires. The study employed a quantitative method to collect and analyse data. The study found that Perceptions on the leadership styles of academic HODs at the HEI are varied. No clear pattern emerged on what leadership styles are prevalent. The relationship between leadership styles and employee job satisfaction appears to be nonlinear. Job satisfaction is a phenomenon that is determined by many factors, not simply leadership styles.

- Description: Eskom Holding is a public limited liability company that supplies electricity. It supplies approximately ninety-nine percent of the electricity used in South Africa, and approximately forty-five percent of that used in Africa. Eskom generates, transmits and distributes electricity to its customers. The Project Execution Department is a department in the Transmission Division that executes the capital and refurbishment of projects. The objective of the study was to discover the opinion of the project team members, on whether there is a lack of project-team efficiency in delivering the projects on time, and within the budget. Descriptive research methodology was used to investigate the objectives of the research. The data were obtained through the structured questionnaires that were hand-delivered and emailed. The research is limited to the Project Execution and Procurement Department in the Transmission Division. The research excludes the Capital Expansion Department (CED) project (Medupi, Kusile and Power Development Projects). The findings of the study showed that, Eskom’s Transmission Project Execution and Commercial Departments need to work hand-in-hand. This will avoid any unnecessary procurement delays which would have an impact on project delivery time. Continuous communication among the project team members could improve the efficiency and serve to build good relationships. Currently, projects are delivered late and over budget. This situation could lead to the outsourcing of departments or even to the redeployment of Senior Management. It would also have a negative impact on the cost and supply of electricity to the country. , Thesis (MSc) -- Faculty of Engineering, the Built Environment and Information Technology, School of the Built Environment and Civil Engineering, 2021

- Description: The role of microorganisms in restoration of the Albany Thicket has not been well documented, although the benefits to plants of these various interactions has been well documented. Microorganisms are chief ecological engineers and assist in resolving environmental problems and act to restore degraded ecosystem function by forming mutual relationships with the roots of the plants. The aim of this study was to assess the potential of microorganisms for the improved biomass production of selected woody and succulent seedlings used in mesic thicket restoration. Three tree species were selected for propagation in this study namely; Mystroxylon aethiopicum Scutia myrtina and Aloe ferox. Soil samples were collected from a degraded and intact thicket site from Bathurst, South Africa. Soils were evaluated for number of arbuscular mycorrhizal (AM) spores, mycorrhizal infectivity potential and nutrient availability both before and after seedling propagation. Pasteurized soil from the degraded site was used in a pot trial. Ten replicates seedling for plant species were planted and subjected to four treatments which included inoculation with AM fungi and the rhizobacterium, Enterobacter sp., alone and in combination; the fourth treatment was an un-inouclated control. Plant growth parameters were recorded at regular intervals where appropriate and seedlings were harvested after 24 weeks for biomass measurements and AM colonisation assessments. Although generally low (< 1 spore per gram) the density of AM fungal spores was significantly higher in soils from the intact site when compared with soils from the degraded site. The mycorrhizal potential of the soils was however not significantly different. Mystroxylon aethiopicum seedling shoot height, canopy diameter and shoot biomass showed a significant increase when inoculated with AM fungi while S. myrtina seedlings showed increased shoot height when inoculated with both AM fungi and Enterobacter sp. Aloe ferox seedlings did not respond to microbial inoculation. The concentration of soil P and Na increased in treatments with Enterobacter sp. alone and in combination with AM fungi. Mystroxylon aethiopicum and S. myrtina seedlings showed a dependency on microbial inoculants indicating the importance of inoculation in the nursery before planting out into the field. Overall AM fungal inoculants applied to seedlings can be used to compensate for nutrient deficiency in soils. Although the Enterobacter isolate used was known to have various plant growth promoting capabilities. It is recommended that other rhizobacterial isolates be investigated. , Thesis (MSc) -- Faculty of Science, Environmental Science, 2017

- Description: This study sought to investigate the practices that the School Management Teams (SMTs) utilize in promoting and monitoring quality teaching and learning in the rural primary schools. The researcher thought it important due to the fact that such actions form part of their central activities. It also aims to explore the kind of difficulties that may be experienced by these formations in rural settings while supporting quality teaching and learning. The main delineations and limitations of this work was that SMTs are supposed to be operational across the spectrum of schools from the first grade to the last one in the high schools. However, due to time constraints and lack of resources, this study was only carried out in three rural primary schools of the king William’s Town district. SMTs are ideally made up of the Principal, Deputy-Principal and HODs (school heads of Department) of these sampled schools who were interviewed. However, in some of the schools under study, the positions of HOD and deputy-principals had already been abolished. The researcher was informed that this was because they had low numbers of learners. In such instances, Senior Teachers were substituted since they are incorporated in the SMTs of those schools. These educators were purposively selected from the foundation, intermediate and senior phases in each primary school. With the research exploring the practices of the SMTs of three rural primary schools, a case study research design was utilized. The research instruments utilized by the researcher to collect data in this case study were Interviews and Document Analysis. The data collected was put into categories and interpreted into common themes. Sources included responses of the participants, school documents, field notes and other relevant documentation such as minutes of the minutes of the SMTs. Constructs, themes and patterns that speak to the strategies used by SMTs in promoting teaching and learning in schools were explored. Briefly, the main findings indicated that the SMTs of the sampled rural primary schools do understand the Departmental policies, but need to be innovative and create space for the practices that they could employ to promote quality teaching and learning. They seem to be working under difficult circumstances. They are grossly over-loaded as full-time administrators and teachers with many learning areas, as well as being responsible for the school nutrition programme. The vacant posts created by retired caretakers added to the overload. There was a concern about the difficulty they were experiencing in the teaching and learning of Mathematics which is nationally regarded as a scarce skill. As an overview of the researcher’s conclusions, it is noted that the SMTs do support the educators to a certain extent. However, there was no documentation that showed how resolutions were made and implemented to validate the nature of support that they give to them. There seemed to be a lack of meaningful parental involvement in the sampled rural primary schools, possibly due to poverty, lack of education and alcohol abuse in the community. Lastly, it seemed to the researcher that there could be uncertainty and uneasiness about the functionality of the senior teachers. Their job descriptions as members of the SMTs remain vaguely defined. In response to the problem statement posed in this study, six major recommendations were made as follows: • Schools, irrespective of their size, ought to have clerks who are able to deal specifically with office administration and external communications. • The teacher-learner ratio as a means of determining the number of educators a school ought to have, should be reviewed as a matter of urgency, if the vital goal of quality teaching and learning is to be realized. • A clear official mandate concerning the job description of senior teachers ought to be established and their positions advertised in that category. This will ensure their equitable distribution as some schools are having them in excess, while others have none. • The department of Education should work with sister departments in government such as Social Development to enforce the law regarding parental negligence. A data basis of negligence parents should be compiled by the concerned departments and reviewed from time to time. Teachers should attend workshops on various policies that govern their roles in the delivery of quality teaching and learning. They need not be conversant with the subject matter only, but also with the relevant policies as a vehicle that facilitates service delivery in education. The introduction of Mathematics support educators who specialized in the learning area should be introduced in each phase of schooling. Such incumbents would rotate from school to school within a circuit, with special reference to rural schools where they would tackle problematic topics as reported by the educators. , Thesis (MEd) -- Faculty of Education, 2012
