- Description: ABSTRACT We report the synthesis of aqueous and organically soluble cadmium selenide (CdSe) nanoparticles (NPs) doped with gold via a facile and effective method. Briefly the synthesis involves the reduction of selenium powder using sodium sulphite to produce sodium selenosulphate which acts as the selenium source, followed by the addition of CdX (X = Cl2, CH3COO, NO3). The nanoparticles were passivated with trisodium citrate, mercaptopropanoic acid (MPA), potassium sodium tartarate (PST) and L-cysteine which rendered them soluble in water and also acted as stabilizing agents, while passivation with hexadecylamine (HDA) made them soluble in organic solvent which also enhanced their stability. The high quality of the as-synthesized nanoparticles was confirmed using absorption and photoluminescence (PL) spectroscopy, Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM) and high resolution TEM (HRTEM). The systematic study of the effect of mole ratio, temperature, capping agent, growth time, cadmium precursor and ratio of Au on the size, optical and structural properties on the water soluble CdSe nanoparticles were investigated. All the as-synthesised particles, are blue-shifted in relation to the bulk band gap of CdSe. As the Cd: Se mole ratio increases, the intensity of the citrate capped CdSe materials also increases and the particle sizes are in the range of 2.06 – 4.00 nm. When the temperature was increased, the luminescence intensity quenched whereas the particle size increased. As the growth time increased, the intensity increased and then decreased again towards the end of the reaction. When different capping agents were used the particle sizes range from 2.06 – 3.36 nm for citrate, 2.08 – 3.33 nm for MPA, 2.01 – 2.28 nm for L-cysteine and polydispersed for PST. The luminescence intensity decreased in the order citrate > cysteine > PST > MPA when CdCl2 was used as cadmium precursor. When different cadmium precursors were used for L-cysteine, the particle sizes range from 2.06 – 2.31 nm for Cd(CH3COO)2 and 2.00 – 2.37 nm for Cd(NO3)2 while the intensity increased as the reaction time increased, however, still lower than the CdCl2 materials. The effect of Au ratio showed that the intensity of Au-doped cysteine capped-CdSe increased as the Au ratio decreased. The systematic study of the effect of temperature and growth time in the organic soluble CdSe nanoparticles on the size, optical and structural properties was also investigated. All the as-synthesised particles were blue-shifted in relation to the bulk CdSe. As the temperature increased the particle sizes of the undoped materials range between 2.92 – 2.95 nm at 160 °C and 5.35 – 5.39 nm at 200 °C while for the doped materials the particle size range from 2.53 – 2.61 nm at 160 °C, 3.97 nm at 200 °C and 4.20 – 4.72 nm at 240 °C. The intensity of the doped materials increased as the reaction time increased and then decreased again towards the end of the reaction. After ligand exchange the intensity of the as-synthesized doped and undoped-CdSe NPs was very low compare to the parent organically capped doped and un-doped CdSe. It was discovered that without any further purification, the quality of the materials formed by this method is comparable to that of the best CdSe NPs reported in the literature. This method is safe, inexpensive and reproducible. , Thesis (MsC Chemistry) -- Faculty of Natural Sciences, 2019

- Description: The study investigated the underlying factors which induce the School Governing Bodies (SGBs) and School Management Teams (SMTs) to boundary cross into each other’s finance functional domain despite the fact that their responsibilities are demarcated in the South African Schools Act No. 84 of 1996. The study also intended to examine financial conscientiousness as a critical strategy, which was aimed at achieving the following: restricting the boundary spanning management among School Governing Bodies and School Management Teams, giving direction and strengthening the relationship between the two structures in section 21 high schools. Pragmatism was used as a paradigm for this study as it has been hailed as one of the best paradigms for justifying the use of mixed methods research. The researcher located the study within mixed methods research and employed the convergent parallel design characterised by collecting concurrently both qualitative and quantitative data. The study used a nonprobability sampling strategy – a purposive sampling technique. The study focused on 147 participants. The sample consisted of the following participant sub-groups: (a) 138 questionnaires participants (46 school principals, 46 SGB chairpersons and 46 school finance officers) sampled from 46 high schools, and (b) 9 face-to-face interviews participants (3 school principals, 3 SGB chairpersons) and purposively sampled from 3 different section 21 high schools located in rural, semi-urban and urban areas of the Butterworth District, and 3 Departmental Officials (The District Director, An Education Development Officer, and District National Norms and Standards for School funding coordinator) sampled from the Butterworth Education District. The study was guided by the following research question: What ideas of consciousness raising strategies could help alleviate the crossing over of boundaries between SGBs and SMTs on financial matters of the section 21 high schools? The financial conscientiousness conceptual framework for this study hinged on the conscious raising concept of Paulo Freire supported by philosophical ideas of theorists of school-based management concept, school-based participative partnership concept, school-based participative management concept and teamwork concept. These theories are expected to encourage the inclusive participation when finances are handled in section 21 high schools. The study used a survey questionnaire to collect quantitative dataset and interviews for the qualitative dataset to find answers to the research question and also to enhance the reliability and validity of the research findings. The quantitative data were presented in tables with frequencies and percentages as well as pie charts. Themes and Natural Meaning Units (NMUs) were used to analyse the qualitative data. The overall findings backed by the extant literature and research data indicated that there was lack of trust among SGBs and SMTs. Owing to this mistrust the day to day activities of the school were compromised. There were power struggles between SGBs and SMTs in schools for the control of school finances. There were corrupt practices by both SGBs and SMTs in the management of school finances. The findings also revealed lack of capacity building by the department of education. Furthermore, the SGBs parent component was characterised by high illiteracy level – a systemic weakness worsened by the manipulation perpetrated by both school governing bodies and school management teams during school finance management processes. Resulting from the data analysis, the study recommended the utilisation and application of Sifuba’s School Finance Management Awareness Model (SSFMA) as a new model that could be adopted and adapted by the Department of Education for the school finance management. This will create educational sound atmosphere and realities at school level – a model that is capable of inducing the participative and inclusive behaviour of the SGBs and SMTs when they perform their financial responsibilities

- Description: The objective of this research study was to describe and explore challenges faced by professional nurses in implementing six ministerial priority standards of care in selected units of an identified institution in O.R. Tambo region. Nurses are trained and employed to provide nursing care to patients according to scope of practice set by their statutory body (South African Nursing Council). Setting of standards forms part of quality improvement in nursing care and standards need to be monitored and evaluated (Muller 2006:206). In South Africa, the Minister of Health has identified six priority areas to fast-track improvement and ensure quality in health services. These priority areas are as follows: attitudes and values of health workers, cleanliness of the facility, waiting times, patient safety and security, infection prevention and control, and availability of medicines (National Health Plan: Strategic plan 2010/2013). Standard of nursing care in OR Tambo region according to available statistics, is lower than the expected ministerial standards, regardless of continued monitoring and evaluation. Staff attitudes is an ongoing problem, long queues, linen shortages, low standards of cleanliness as well as shortage of medication remain a challenge in health care institutions. This study is a qualitative, descriptive, exploratory, and contextual study that explored challenges faced by professional nurses in implementing the six ministerial priority standards of care. A purposive sampling of 10 professional nurses, meeting the selection criteria was utilised. In depth, semi structured interviews were used as a method of data collection. A digital voice recorder was used to record the interviews and consent from participants was obtained. Ethical considerations were adhered to. The interview question was: “What challenges are you facing in implementing expected standards of care with reference to the six ministerial priority standards of care?” Data was analysed using content thematic analysis approach. An independent coder with a Master’s degree and studying towards a doctorate helped with coding the results of the interviews. The Theory for Health Promotion in nursing as propounded by Botes (2006) was used to analyse the findings. The approach used was based on the external environment and its dimensions – social, physical and intellectual. v The findings of the research revealed the following themes: Lack of resources, demotivation of nurses, attitude of nurses, lack of monitoring and evaluation, environment and overcrowding, lack of patient safety, negligence, availability of policy and procedure manuals, and incompetency of health care professionals. The findings of this study revealed that nurses faced many challenges with regard to improving the standard of nursing care. According to Botes (2006), the purpose of nursing research is functional by nature, it provides guidelines for practice. Therefore in this study, a description of guidelines to improve nursing care has been done. Trustworthiness of the findings was ensured by utilising Lincoln and Guba’s model of trustworthiness. Limitations of the research are highlighted and recommendations for further and related studies are made.

- Description: The purpose of this study was to examine the challenges facing the teaching and learning of Accounting in secondary schools of the Mthatha education district. There are 69 secondary schools that offer Accounting in the Mthatha education district. In order to attain the objectives and fulfil the aim of the study, the researcher used the qualitative research approach, both in collecting and analysing the data. The case study design was used to describe and access the phenomenon of challenges facing the teaching and learning of Accounting in the Mthatha education district. Convenience sampling method was used to select twelve Accounting teachers from six different secondary schools in the Mthatha education district. Face-to-face in-depth interviews and non-participant observation were used to collect the data. Themes were drawn from the responses of the participants and these were analysed. The study revealed the following factors as challenges facing the teaching and learning of Accounting in secondary schools of the Mthatha education district: Teachers had professional qualifications in teaching, but fewer of them had Accounting as subject of their specialisation. Frequency of workshops was identified as a challenge by interviewed teachers. The study revealed that teachers are unfamiliar with the content to teach, and as a result, they are unable to develop the learner guides. The study found that teachers are using insufficient LTSM to teach Accounting. Instructional strategies used by teachers for teaching and learning of Accounting affected the process of teaching and learning of this subject. Redeployment is a challenge that affects the capacity of schools in the teaching and learning of Accounting. The study also revealed that there is a lack of parental involvement and support in the education of their children, which negatively affects the teaching and learning of Accounting. Limited commitment from teachers and learners was also revealed as one of the challenges in teaching and learning Accounting. The researcher made recommendations towards mitigating the effects of the challenges in teaching and learning of Accounting.

- Description: The dawn of democracy in South Africa necessitated some changes in many spheres of government including education. There was a dire need for educational transformation from the apartheid education system, which favoured white South Africans, to an inclusive education system. This transformation was crucial to address and/or redress the neglect and/or exclusion of certain learning areas and methods in the school curriculum, especially in South African rural schools. Furthermore, it was needed in order to provide a uniform education system for all South Africans under one Department of Education. The first South African curriculum restructuring innovation resulted in Curriculum 2000 which was later renamed Curriculum 2005 (C2005). The review of C2005, in an attempt to assess progress in its implementation, revealed enormous challenges. Thus, in an attempt to strengthen C2005 the Revised National Curriculum Statement (RNCS): grades R-9 and the National Curriculum Statement (NCS): grades 10-12 were introduced. These two curricula were followed by the National Curriculum Statement (NCS): grades R-12. There is, however, overwhelming evidence that C2005 and the curricula that followed thereafter faced huge problems in their implementation. The purpose of this study, therefore, was to examine the complementarity between curriculum design and development processes, and curriculum implementation in the South African education arena. This study was located within the pragmatic paradigm and used mixed methods research design. In this study complementarity of curriculum design and development and curriculum implementation refers to the ability of curriculum design and development processes to have comprehensive provisions for curriculum implementation. The investigation of this complementarity was conducted through the exploration of the main research question: What complementarity existed between the process of curriculum design and development, and curriculum implementation in South Africa? Other subsidiary questions were also derived from the above main research question.ii Thirty schools from the population of schools in the Libode Mega-District were randomly sampled from which sixty participants in the study had been selected. All data in the study were obtained from these participants. Questionnaires and in-depth interviews were the instruments used to collect data. In-depth interviews were conducted with fifteen participants after the researcher had collected all questionnaires. Data collected through the use of questionnaires were analysed using descriptive statistics obtained through the use of the Statistical Package for Social Science (SPSS). Data collected through interviews were first coded to form units according to similarities and/or differences among units. Units were thereafter grouped into clusters to form domains in order to discover relationships between these domains. Challenges that faced curricula implementation, as per the findings of this study, included: inadequate teacher training, ineffective methods used in curricula dissemination, lack of infrastructure, lack of adequate support from other stakeholders, lack of teacher involvement in curricula design processes, and lack of teaching and learning material. The present study concluded that there was no complementarity in the curriculum design and development processes and curriculum implementation. This study recommended, among other things, that the DBE should provide effective programmes on teacher training in preparation for curricula implementation, ensure availability of human and material resources and infrastructure and also teacher involvement in the curricula designing processes.

- Description: The dawn of democracy in South Africa necessitated some changes in many spheres of government including education. There was a dire need for educational transformation from the apartheid education system, which favoured white South Africans, to an inclusive education system. This transformation was crucial to address and/or redress the neglect and/or exclusion of certain learning areas and methods in the school curriculum, especially in South African rural schools. Furthermore, it was needed in order to provide a uniform education system for all South Africans under one Department of Education. The first South African curriculum restructuring innovation resulted in Curriculum 2000 which was later renamed Curriculum 2005 (C2005). The review of C2005, in an attempt to assess progress in its implementation, revealed enormous challenges. Thus, in an attempt to strengthen C2005 the Revised National Curriculum Statement (RNCS): grades R-9 and the National Curriculum Statement (NCS): grades 10-12 were introduced. These two curricula were followed by the National Curriculum Statement (NCS): grades R-12. There is, however, overwhelming evidence that C2005 and the curricula that followed thereafter faced huge problems in their implementation. The purpose of this study, therefore, was to examine the complementarity between curriculum design and development processes, and curriculum implementation in the South African education arena. This study was located within the pragmatic paradigm and used mixed methods research design. In this study complementarity of curriculum design and development and curriculum implementation refers to the ability of curriculum design and development processes to have comprehensive provisions for curriculum implementation. The investigation of this complementarity was conducted through the exploration of the main research question: What complementarity existed between the process of curriculum design and development, and curriculum implementation in South Africa? Other subsidiary questions were also derived from the above main research question.ii Thirty schools from the population of schools in the Libode Mega-District were randomly sampled from which sixty participants in the study had been selected. All data in the study were obtained from these participants. Questionnaires and in-depth interviews were the instruments used to collect data. In-depth interviews were conducted with fifteen participants after the researcher had collected all questionnaires. Data collected through the use of questionnaires were analysed using descriptive statistics obtained through the use of the Statistical Package for Social Science (SPSS). Data collected through interviews were first coded to form units according to similarities and/or differences among units. Units were thereafter grouped into clusters to form domains in order to discover relationships between these domains. Challenges that faced curricula implementation, as per the findings of this study, included: inadequate teacher training, ineffective methods used in curricula dissemination, lack of infrastructure, lack of adequate support from other stakeholders, lack of teacher involvement in curricula design processes, and lack of teaching and learning material. The present study concluded that there was no complementarity in the curriculum design and development processes and curriculum implementation. This study recommended, among other things, that the DBE should provide effective programmes on teacher training in preparation for curricula implementation, ensure availability of human and material resources and infrastructure and also teacher involvement in the curricula designing processes.

- Description: The purpose of this study was to investigate the factors contributing to conflict among the teachers of secondary schools of Mthatha Education district. The liter-ature review reflects theories concerning the factors contributing to conflict among teachers, ranging from the leadership styles use in the schools, the causes of poor in-terpersonal relations among teachers and the causes of teachers’ resistance in schools. To attain the aims and objectives of the study the researcher used the case study de-sign as well as the qualitative research method, both in collecting and analysing the da-ta. Ten (10) teachers and five (5) principals from five different secondary schools formed the sample size of the investigation. Convenience sampling method was used to select this sample size. An open-ended interview schedule and tape record-ing were used for the face-to-face in-depth interviews. Themes drawn from the re-sponses of the participants and discussed included: unhealthy competition, poor com-munication, poor interpersonal relations, poor leadership styles used in schools, exces-sive teacher workload and the existence of cliques and informal groups resulted into conflict among the secondary school teachers. Democratic and participatory styles were suggested as the best working styles of leadership used in the secondary schools. The effects of conflict on the culture of teaching and learning were: weak team spirit among teachers, less communication, stressed among the teachers, high absenteeism, less col-laboration, less teacher motivation and prolonged decision making processes in the schools. The predominant causes of teacher resistance were also highlighted as: the use of autocratic style by school managers, poor communications, ill and unprofessional treatment of staff by managers, constant curriculum changes and unclear policies in the schools. The recommendations on the factors contributing to conflict among sec-ondary schools in the Mthatha Education District were made.

- Description: Medicinal plants have long been used in folkloric medicine in various parts of the world. Presence of phenolic compounds has been attributed to their medicinal properties. Despite various medicinal uses, scientific claims of anti-hypertensive activities are still deficient. Therefore, hydroethanolic (70% ethanol) extracts of the leaf and root parts of T. officinale (TOL and TOR respectively) were investigated for anti-hypertensive antioxidant, diuretic activities, and effects on lipid profile in L-Name-induced hypertensive Wistar rats. Phytochemical screening of TOL and TOR was assessed by known standardized method. Acute toxicity profile of the plant was also evaluated by Lorke’s method. Total phenolic and flavonoid contents were assessed using Folin Ciocalteau and Aluminium chloride colorimetric methods; while, 2, 2-diphenyl-1-picrylhydrazyl (DPPH), 2, 2’–azino-bis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS)and ferric antioxidant reducing power (FRAP) protocols were used for their radical scavenging and total antioxidant capacities respectively. Spontaneously hypertensive rats were used for acute antihypertensive study while for the 21 days antihypertensive study, hypertension was induced by administering L-Name (40 mg/kg) for 4 weeks and, CODA 8 Non-invasive tail cuff machine was used to measure blood pressure. With the aid of a semi-auto chemistry analyzer, lipid profile of Taraxacum officinale (TO) was determined using Biosinol reagents. TOL and TOR also significantly reduced systolic, diastolic and mean arterial blood pressures up until 4 hours with the leaf part most active in single dose study using SHR model. TOL and TOR also significantly lowered systolic, diastolic and mean arterial blood pressures with the leaf part most active in 21 days study using and L-Name-induced HTN models. However, these plant extracts did not have a diuretic effect, but seems to exert its antihypertensive effects by modulating NO production and possibly bioavailability, by acting via an endothelium-dependent pathway. This study validates the traditional use of the leaf part of the plant as an antihypertensive agent.

- Description: Nurses are an integral part of the health care system and their job encompasses a wide range of responsibilities including the promotion of health, prevention of illness and care for physically, mentally ill and disabled people. Nurses have a mandate to be responsible and accountable to the public they serve. For these reasons, it is crucial that nurses possess attitudes that allow them to provide optimal care in a supportive manner for patients. Despite the fact that considerable research on the experiences of nurses caring for the mentally ill in general hospitals has been done globally, none has been conducted in the Eastern Cape, South Africa. Additionally, no studies could be obtained from anywhere in the world on the experiences of non-psychiatric trained nurses caring for mental health care users on 72 hour observations. Studies indicated that nurses have different experiences when caring for mental health care users. It was therefore considered necessary to find out how non-psychiatric trained nurses perceive the caring of mental health care users during the 72 hour observations. The research design used to explore and describe their experiences was qualitative, descriptive, explorative, phenomenological and contextual in character. Semi-structured interviews were conducted with eight (8) participants who were purposively selected. This was done after necessary permission from the Department of Health and informed consent from the research participants. Steps were taken throughout the course of the study to ensure trustworthiness. Data were analysed using Tesch’s methods and the services of an independent coder were used. The results indicate that there are different experiences with regard to the caring for mental health care users during the 72 hour observations. The major themes identified are: feelings experienced by these nurses, lack of knowledge, challenges and strategies used for coping with a violent user, need for support from security staff and lack of policies. v Guidelines as a supportive action are suggested. From the results of the study recommendations are made in the areas of nursing education, nursing practice and nursing research. It is concluded that for non-psychiatric trained nurses to provide optimal care to mental health care users, the nurses need knowledge and skills in order to facilitate the promotion, maintenance and restoration of mental health of these patients as an integral part of health.

- Description: The purpose of this study was to investigate the managerial leadership styles of school principals for school effectiveness at secondary schools of the Dutywa Education District in the Eastern Cape Province of the Republic of South. The literature review reflects theories concerning the managerial leadership styles of school principals for school effectiveness. In order to attain the aims and objectives of the study, the researcher used the qualitative research method, both in collecting and analyzing the data. The case study design was used to describe and access the phenomenon and the purposive sampling method was used to select (6) secondary school principals. An open ended interview schedule was used for the face-to-face in-depth interviews on the managerial leadership styles of school principals for school effectiveness at secondary schools of the Dutywa Education District. Themes were drawn from the responses of the participants and analysed. Some of the findings were: Democratic and participatory leadership styles were used by the school principals to achieve maximum co-operation from both experienced and beginning teachers and the learners in the schools. Laissez fair and autocratic styles of leadership appeared to be undesirable for the management of schools. For school principals’ effective management, they need to do proper planning, organising and scheduling of activities, assigning duties to teachers and delegating some of their work to competent teachers. The reasons for school principals’ ineffectiveness in this study were: favouritism, over-familiar relationships with some teachers, ignoring teachers’ personal problems, workload, lack of support and co-operation from teachers. Incorrect interpretation of educational policies were seen to lead to chaotic situations, poor performance of both teachers and learners, division between learners and teachers, a lack of unity between school stake-holders, poor job satisfaction and lack of trust and respect for the principals concerned. Factors contributing to principals’ incorrect interpretation of educational policies and execution of management roles were: negligence, lack of knowledge and ability to interpret educational policies, lack of proper induction programmes and training of principals and lack of support on policy matters from the Department of Education. Contributing factors resulting in barriers to principals’ ineffectiveness in the management of schools were: failure to give proper instructions to teachers and learners, failure to effectively use of available funds in the school, failure to implement all educational programmes in the school including co-curricular and extra mural activities, lack of experience, lack of support from both the Department of Education and the parents, lack of resources, high staff turnover, favourtisms and failure to hold teachers accountable for poor work done. Mechanisms deemed to overcome the factors leading to barriers to principals’ execution of their management roles at schools were: making the effort to be knowledgeable about educational policies, timely responses to problems in the school, regular consultation with stakeholders, employment of SGB teachers, taking direct supervision of instructions in classrooms and endeavoring to have good relations and gaining support from the SGB and the parents. The researcher made some recommendations on the managerial leadership styles of school principals for school effectiveness at secondary schools of the Dutywa Education District.

- Description: The study sought to assess the impact on learners‘ academic performance of the management of the quality of education in South African schools. The study was conducted in ten independent and ten public schools in Mthatha. The study elicited information for quantitative data from 60 school management team (SMT) members, 200 educators and 400 learners who were randomly sampled from the participating purposively sampled schools. Qualitative data and document analysis were used to triangulate quantitative findings. Data collected was coded and analysed thematically. Quantitative data were analysed with the aid of the SPSS version 22 and qualitative data were analysed through content analysis. Quantitative data were presented through a blend of both descriptive and inferential statistics using tables and graphs. The study found that school management teams (SMTs) and educators were more aware than learners that there are national and provincial legislation mandates that guide the management of quality in education. However, stakeholders were of the view that schools did not use relevant national, provincial and school-based policies and procedures to guide the provision and management of quality in education. It also emerged that learners did not conduct themselves in a manner that promoted the provision of quality education. Participants were, nevertheless agreeable on the indicators of high-quality education. SMTs and educators held stronger views than learners about schools having clear vision and mission statements (VMS) in place but neither were displayed for all to see nor were they well known to and supported by the ii SMTs, educators and learners, thus they were not implemented. The study also established that respondents were aware of the educator-centred, SMT-centred as well as learner-centred factors that affected the quality of education and that factors that promote high-quality education were largely absent in schools. Stakeholders also agreed about the effects of factors that affected the quality of education on learner performance such as poor training and development of educators. It emerged that there were positive SMT-centred factors such as promoting professional development of staff; educator-centred factors including maintaining exceptional lesson planning standards and presentation skills; learner-centred factors being geared towards school work while high parental involvement in school activities emerged as the overriding home-based factor noted to have a strong, positive impact on the provision of quality education and learner performance. It also emerged from the study that inter-alia, stakeholders viewed performance measurement and management as important and holding SMTs and educators accountable for poor school performance as an imperative measure for the provision of quality education. Recommendations for practice and for further research were made with a view to improving the management of the quality of education in schools. In light of that, a model for the management of the quality of education and learner performance was proposed.

Quantitative data were analysed with the aid of the SPSS version 22 and qualitative data were analysed through content analysis. Quantitative data were presented through a blend of both descriptive and inferential statistics using tables and graphs. The study found that school management teams (SMTs) and educators were more aware than learners that there are national and provincial legislation mandates that guide the management of quality in education. However, stakeholders were of the view that schools did not use relevant national, provincial and school-based policies and procedures to guide the provision and management of quality in education. It also emerged that learners did not conduct themselves in a manner that promoted the provision of quality education. Participants were, nevertheless agreeable on the indicators of high-quality education. SMTs and educators held stronger views than learners about schools having clear vision and mission statements (VMS) in place but neither were displayed for all to see nor were they well known to and supported by the ii SMTs, educators and learners, thus they were not implemented. The study also established that respondents were aware of the educator-centred, SMT-centred as well as learner-centred factors that affected the quality of education and that factors that promote high-quality education were largely absent in schools. Stakeholders also agreed about the effects of factors that affected the quality of education on learner performance such as poor training and development of educators. It emerged that there were positive SMT-centred factors such as promoting professional development of staff; educator-centred factors including maintaining exceptional lesson planning standards and presentation skills; learner-centred factors being geared towards school work while high parental involvement in school activities emerged as the overriding home-based factor noted to have a strong, positive impact on the provision of quality education and learner performance. It also emerged from the study that inter-alia, stakeholders viewed performance measurement and management as important and holding SMTs and educators accountable for poor school performance as an imperative measure for the provision of quality education. Recommendations for practice and for further research were made with a view to improving the management of the quality of education in schools. In light of that, a model for the management of the quality of education and learner performance was proposed.

- Description: This study sought to investigate challenges faced by teachers in applying reading strategies when teaching reading in the Foundation Phase in the Mthatha District in South Africa. The study was conducted at Four Junior Secondary Schools. It was prompted by a deep concern about challenges faced by teachers in applying reading strategies required in the Foundation Phase. While studies have been carried out on applying reading strategies in the Foundation Phase, few studies have looked at the factors impacting on reading in South African schools, especially in the Mthatha District where isiXhosa is the mother tongue. The method used in this study involved a qualitative approach. The study addressed the following research questions: What strategies are used in the Foundation Phase? What type of challenges are faced by teachers? To what extent are educators trained to teach reading in the Foundation Phase? Does the lack of resources affect the performance of learners? To what extent does the use of a second language affect the performance of Foundation Phase learners? Do teachers receive enough support from the Department of Education to teach reading? The study is a multiple-case study and data were collected through individual interviews and focus group interviews (sixteen teachers were interviewed). Content analysis guided the data analysis through themes derived from the subsidiary questions. Data reporting took the form of thick description and verbatim quotations in line with the qualitative approach of the study. A pilot study was conducted in two Junior Secondary Schools for the purpose of validity and reliability. ii The study`s findings revealed that: Different reading strategies were used by teachers in the Foundation Phase, teachers faced many challenges in applying reading strategies such as teacher training in the teaching of reading. This suggests that intervention is needed by the Department of Education such as providing relevant resources which are essential in order to address the problem of reading. Improvisation by teachers to improve reading material, insufficient allocation of time, multilingualism, teacher competence, lack of motivation and parental involvement in relation to learner performance in reading all need attention in order to solve problems. Furthermore, lack of resources hinders the reading ability of learners. The use of home language as a medium of instruction in teaching reading is highlighted. There is insufficient support by the Department of Education for Foundation Phase teachers to teach reading. Based on the study findings, the researcher has recommended that teachers should be urged to use reading strategies in a way that benefits learners. The use of reading strategies, therefore, needs more attention. Libraries should be built in these schools to enable learners to develop a culture of reading. Education development officers, subject advisors, lead teachers and parents should work together to improve the reading ability of Foundation Phase learners.

- Description: Background: Dysfunction of the vascular endothelium is an early finding in the progression of cardiovascular disease and is closely related to clinical events in patients with obesity and hypertension. Vascular function is mediated by nitric oxide (NO) and endothelin (ET-1) which serve as natural counterparts. The aim of the study was to determine the physiological effects of HIV infection, blood pressure and body composition on the changes of ET-1 and NO and association between ET-1 and NO. Methods and results: This was a descriptive and comparative study. A Quota sample method was used. The study population consisted of 154 participants categorized into the following groups: 57 HIV negative participants (A), 40 HIV positive not on treatment participants and 57 HIV positive on treatment participants. Enzyme immunoassay kit was used for the quantitative determination of ET-1 and Nitrate/nitrite colorimetric assay kit was used for the determination of NO. Anthropometric measurements, body composition were determined. Hemodynamic measurements were also taken into account. Results: Resting metabolism, waist circumference (WC) and hip circumference had low mean levels in both HIV positives groups compared to HIV negative group. On lipid profiles visceral fat (VF), whole fat (WF) had low mean levels but skeletal muscle fat (SMF) showed the highest mean levels in both HIV positive groups. All the blood pressures between HIV groups were on a normal range scale. Mean values of endothelin and nitric oxide are increased in HIV positive not on ART and HIV (+) on ART compared with the HIV negative group. Conclusion: NO, ET-1, ART and HIV itself were associated with the pathogenesis of endothelial dysfunction in persons with HIV infection. Elevated endothelial markers namely ET-1 and NO can lead to improvement of endothelium dependent relaxation to some extent but not completely. Although these markers have deleterious effect on the endothelium but can also serve as up-regulator of hypertension. Key words: HIV-infection, antiretroviral therapy, endothelial dysfunction, Endothelin1 (ET-1), nitric oxide (NO), blood pressures (BPs). , Thesis (MSc) -- Faculty of Health Sciences, 2015

- Description: The purpose of this study was to investigate the factors contributing towards the decline of learners in rural junior secondary schools in the Qumbu Education District in the Eastern Cape, South Africa. This was done because in South Africa before the 1994 elections rural schools were not supported by the apartheid government. Rural areas were disadvantaged in education, in terms of finance. This resulted in poor quality of teaching and learning. Declining numbers of learners in rural schools was occurring in all rural schools. Staffs were alarmed by the declining enrolment of learners in their schools because their schools were affected. Teachers were redeployed to schools where there were sufficient learner numbers. Department of Education due to declining learner numbers in schools introduced rationalisation and re-alignment of schools, meaning closure of some schools with low learner numbers. This led to learners walking long distances to schools. This study was conducted in the Qumbu Education District. It focused on declining numbers of learner enrolment. The literature internationally focused on declining number in enrolment of learners. These learners were afraid of Physical Science (Chemistry side) as a subject. They had taken Chemistry as difficult because of the perceived link with Mathematics. Continentally the literature had alluded to teenage pregnancy, affected and infected learners with HIV/AIDS and human trafficking. In South Africa literature focused on the educational level of parents. Learners with educated parents leave rural schools to study in urban areas because of poor education which is provided in rural areas. Lack of resources in these schools could also be the cause of declining learner numbers in rural junior secondary schools. The study used a quantitative research design to elicit data from the respondents. The respondents in this study were 50 principals of the sampled rural junior secondary schools. Data was collected from 50 participants through the use of a questionnaire; 50 questionnaires were returned and the data which was finally processed was from these 50 questionnaires. The Statistical Package for Social Sciences (SPSS) was used for the analysis of the data. iii The findings of the study revealed that factors such as lack of parental involvement, socio-economic factors, HIV/AIDS - related issues, culture and gender - related issues, lack of resources, teacher and teaching - related issues and the education level of the parents were the contributing factors to the decline in enrolment of learners in rural junior secondary schools in the Qumbu Education District. In the light of the findings, the researcher recommends that more tuition time and the reduction of absenteeism by teachers can help reduce the decline of enrolment in rural junior schools in the Qumbu area. The Department must consider the number of learning areas and not teacher - pupil ratio. The Department should also introduce computer classes, woodwork, bricklaying and other practical skill subjects in these schools. Furthermore there must be resources such as laboratories, libraries and television. Some of the limitations encountered by the researcher during the study included the reluctance of the participants to take part in the research, the inaccessibility of schools in deep rural areas, the slow return rate of completed questionnaires and the obtaining of permission to undertake the study.

- Description: Children from low socio-economic communities in the Eastern Cape Province of South Africa and in South Africa at large are frequently infected by intestinal parasites. The parasites are diverse and complex pathogens that include multi-cellular helminths and single-celled protozoa. Because of this diversity, immunity to parasites is more difficult to sustain. Tuberculosis also, remains a problem in South Africa and worldwide. Infection with Mycobacterium tuberculosis can result either in the disease itself or, more commonly, latent infection. A variety of mechanisms that include both humoral and cell mediated immunity achieve host protection against mycobacterial pathogens. Macrophages and cell-mediated immunity are the primary defence mechanisms against mycobacteria. According to the literature, parasitic infections impair the body’s immune response to tuberculosis, but these diseases are not adequately researched in this province. The extent to which the school children of Mthatha are infected with intestinal parasites and latent tuberculosis, or even how their immune systems respond to these infections have not been investigated. Therefore, the immune response of school children, both of those infected and those not infected with parasites, to specific Mycobacterium tuberculosis antigens was evaluated. The present study used two study design methods: firstly, a descriptive cross-sectional design for the prevalence rates of intestinal parasites and, secondly, a case-control study for comparison of interferon gamma and T-helper 1 and T-helper 2 cytokines in parasite infected and non-parasite infected participants. A total of 137 school children participated in the survey and all were analyzed for parasites. Due to the high cost of the reagent kits, only 75 participants were included in the case-control study. Data collection methods: i) for the prevalence of intestinal parasites, formalin ethyl acetate sedimentation technique was used to process stool specimens, ii) for immune response to Mycobacterium tuberculosis antigens (measurement of interferon gamma for latent tuberculosis),the QuantiFeron TB Gold In-Tube assay was used, and iii) for the quantification of Th1 and Th2 cytokines, the Bio-Plex Pro assay was used. Out of 137 school children analyzed, 66.4% (91/137) were positive for parasites (ova and cysts). The most prevalent parasite was the pathogenic helminth, Ascaris lumbricoides at 21.9% (30/137), followed by Trichuris trichiura at 8.8%. The pathogenic protozoa, Giardia lamblia and Blastocystis hominis were both at 2.9% (4/137). The non-pathogenic protozoa, Entamoeba coli and Endolimax nana had high prevalence rates at 32.1% (44/137) and 29.2% (40/137) respectively. Associations between parasitic infections and sociodemographics showed a significant difference in participants whose parents had a low level of education and those who were unemployed (P = 0.004; P = 0.005 respectively). Out of 75 participants analyzed for tuberculosis, 53.3% (40/75) were positive. In conclusion, the present study demonstrates high prevalence rates of parasitic as well as latent tuberculosis infections in Mthatha. The study also showed that intestinal parasites, especially helminths, interfere with immune responses to TB by down-regulating Th1 response leading to reduced production of interferon gamma, a cytokine that mediates protection against TB.

- Description: This research study examined the role of management by school managers in the three strata schools of the Mthatha Education District in the Province of the Eastern Cape of South Africa. The researcher tried to show how School managers provide a leadership role especially in the Mthatha schools in the Eastern Cape Province of South Africa. It was deduced from the statistical data presented that there is a significant correlation between a school manager’s tasks and the quality of education. This shows that when school managers plan properly, organizing properly, leading and control management task be better all resources of the school will be managed better. The proper execution of management tasks of planning, organizing, leading and control by school managers have contributed extensively to the success of schools. The researcher used both qualitative and quantitative methods in –order to collect data. Two instruments namely, questionnaires and interviews were used in –order to collect data. Tools used during quantitative research design data collection are questionnaires. Questionnaires were used in order to pilot the study for the purposes of identifying with rich information. The researcher used structured questions for quantitative questionnaires. Respondents answered questionnaires in the absence of the researcher in-order to allow anonymity and a stress –free environment. Tools used for the qualitative research design data collection method were interviews. Interviews were used for the information rich subjects. During interviews, the researcher used face-to-face, one- to- one interviews with each subject. The sample subjects in this study for the quantitative method were school managers of Mthatha schools. The total number of participants was 14. All of them returned their questionnaire responses at the agreed time with the researcher. Amongst the findings that emerged were; a high level of enthusiasm in all three schools for change; however, different kinds of hindrances were experienced. ii Finally, recommendations and suggestions were made starting that schools have to follow strict management /leadership programs.
