- Description: Poverty is recognised as one of the greatest challenges faced by developing and the least developed countries. South Africa has been no different with increased levels of poverty which are also inherit from the substantial inequality in the country. Thus, food security programmes have become an innovative way to tackle the issue of poverty across municipalities. Taking a qualitative and quantitative root within the Buffallo City Municipality located in the Eastern Cape, this study evaluated the impact these programmes have on household food security. Through surveys and interviews with participants in the Siyazondla and Siyakhula food programme instituted by department of rural development and agrarian reform (DRDAR) the findings show that beneficiaries benefited heavily from the programmes. Several households reported increased scale of food supply due to programmes such as the gardening projects and inputs within the agricultural process particularly; seeds, fertilizer and equipment neccesary for planting. Thus, conclusively, the outcome of these food security programmes has been positive and it is adviced that the department of rural development and agrarian reform (DRDAR) increase the population of households in the projects offered by the department. Moreover, these projects should be implimented to provide means which could enable communities to continue the projects without need for dependence. This would entail providing individuals with the neccesary skills and education to continue these projects within their households at limited costs. , Thesis (MA) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 2021

- Description: Polymineralic inclusions encapsulating a daughter assemblage of crystalline phases (including silicates, oxides, and carbonates) and an amorphous glass phase, hosted in ilmenite megacrysts from the Monastery kimberlite, were investigated texturally and geochemically in order to constrain their melt origin, modeof formation, and evolution prior to quenching. The isolated nature of the melt inclusions within the ilmenite megacrysts provides an opportunity to study components of primary kimberlitic magma captured within the SCLM (4.5–6 GPa) that has been isolated from pervasive modifying processes that are common in kimberlites. The common daughter phase assemblage within the melt inclusions comprises serpentine, phlogopite, calcite, spinel, kassite, perovskite, ilmenite, and glass. The glass is Si-Mg-Fe-rich, with low Al2O3 contents. It is also K2O- and TiO2-free, with variably depleted REE. In composition, serpentine forms a crystalline equivalent to the glass. However, these phases are optically distinct. Serpentine represents two modes of formation: (i) discrete euhedral grains set within a glass matrix that represent a primary phase, crystallising directly from the entrapped melts, and (ii) as patches of partially crystallised glass that represent a secondary phase formed by the devitrification of the glass. Spinel and phlogopite form along early kimberlitic evolutionary trends and record the depletion of the melt in TiO2, Al2O3, and K2O, which typically decreases from the core to the rim of the crystals. Volatile and alkali-bearing minerals (calcite, apatite, phlogopite) crystallised within the melt inclusions from the captured alkali-rich carbonated-silicate kimberlite melt. The daughter mineral assemblage initially crystallised as euhedral and subhedral grains with a uniform composition under equilibrium conditions. Subsequent crystallisation formed grains that exhibit magmatic zoning due to their crystallisation in a progressively depleted melt. Lastly, the crystallisation of skeletal oxide grains occurred under disequilibrium conditions, at a stage of magma ascent with rapidly changing variables including temperature, melt viscosity, and diffusivity. Prior to complete crystallisation, the residual Si-Mg-Fe melt of this crystallisation process was quenched to form the observed glass. The phases that constitute the common daughter assemblage show large variations in modal proportions, forming a continuum from silicate-rich to carbonate-rich endmember inclusions, with certain daughter phases absent in some inclusions. This suggests that the melt was heterogenous at the time of capture and comprised immiscible silicic/oxidic and carbonate melts. Phase separation, therefore, may have started prior to capturing of magma batches as inclusions in ilmenite, but further segregation and crystallisation continued after these batches had become isolated from the megacryst matrix as melt inclusions. The immiscibility and co-existence of the silicic/oxidic and carbonate melts is preserved by textural features between calcite and glass, such as rounded globules of calcite grains set within a silicate glass matrix, calcite forming the matrix for euhedral silicate and oxide minerals, and calcite occupying the interior void of skeletal oxide grains set within a silicate glass matrix. Furthermore, spherulitic globular domains of Ca- and Ti-rich glasses set within a matrix of the Si-Mg-Fe glass suggest that the silicic/oxidic melt underwent further segregation into oxide-rich (Ca-Ti) and silicate-rich (Si-Mg-Fe-Al-K-Ti) melts, potentially crystallising the oxide and silicate minerals of the daughter assemblage, respectively. The abundance of incompatible trace elements and the Cr-poor composition of secondary low-Mg ilmenite as a daughter mineral within the melt inclusions (~1400 ppm Nb; <0.1 wt% Cr2O3; <0.1 wt% MgO), in addition to the Cr-poor composition of the other daughter phases within the inclusions (i.e. <0.1 wt% Cr2O3 for phlogopite and spinel), indicate that they crystallised from a similar melt as the Cr-poor, but high Mg-ilmenite megacrysts (~1400 ppm Nb; <0.1 wt% Cr2O3; ~10 wt% MgO). Furthermore, the melt inclusions are randomly distributed and no textural and/or geochemical evidence for melt infiltration of the ilmenite megacrysts was associated with the melt inclusions. These features are consistent with a primary origin for the melt inclusions which implies a cognate relationship between the megacrysts and the captured kimberlite melt. , Thesis (MSc) -- Faculty of Science, Geology, 2021

- Description: In order to handle the capacity shortfall of state-funded universities in developing economies, governments with limited public resources often establish systems and regulations that enable private organisations to provide equivalent qualifications. As such, South Africa (SA) has seen a large growth in the number of registered private higher education institutions (HEIs) offering alternatives to students who are seeking higher education qualifications but do not meet public universities admission criteria. The emergence of private HEIs has resulted in a different type of learning environment. These institutions provide smaller classes than their public counterparts and a faculty which often consists of both part-time and full-time retired public HEIs lecturers and industry experts, in an environment that is more practical, and less research focused. Due to the substantial differences between the public and private higher education sector mandate, the educational quality produced by private HEIs is often a contentious subject among academics. Employer perspectives are that most graduates do not have the necessary work-ready skills to successfully integrate into the workforce. While various studies have attempted to define and measure graduate employability, limited research differentiates between public and private HEI graduates, and even fewer studies compare the level of graduate employability between these two sectors. In an attempt to determine whether any statistically significant differences exist between the graduate attributes of public and private higher education commerce students in SA, this study makes use of the Graduate Skills and Attributes Scale (GSAS). The GSAS clusters eight graduate skills and behaviours into the three holistic, overarching attitudinal domains of personal and intellectual development. These eight graduate attributes include interactive skills, problem-solving and decision-making skills, continuous learning orientation, enterprising skills, presenting and applying information skills, goal-directed behaviour, ethical and responsible behaviour, and analytical thinking skills. Using a quantitative approach, questionnaires were distributed to a total of 416 respondents, consisting of 351 public and 65 private higher education commerce students within SA. The sample consisted of students enrolled in their final year of study, through either a public university or registered private HEI situated within SA, completing a Higher Education Qualifications Sub-Framework (HEQSF) accredited NQF 7 Bachelor of Commerce (B.Com) degree through contact mode of study. After the data collection, independent samples t-tests were used to compare the graduate attributes of the two sectors. The study concludes that higher levels of interactive skills and continuous learning orientation were present among students attending private HEIs, while the remaining six graduate attributes indicated no significant differences between the two sectors. The results of this study provide valuable information to HEIs, students, industry and government, as it measures and compares the level of graduate quality produced by public and private HEIs within SA. , Thesis (MCom) -- Faculty of Management and Commerce, 2020

- Description: Abstract The main objective of this study has been to investigate the implementation of the affirmative action on the basis of gender balancing in the Department of Education in Mthatha District offices. The affirmative action policy is the program that seeks to remedy the past discrimination ideologies like on the bases of race and gender. Gender discrimination seemed to be the worst kind of discrimination in the past. Even within the same race, there are gender biases as well as within the same classes, women are treated differently. Some women are experiencing the impact of racial discrimination and class discrimination which puts women secondary of their same racial or same class male counterpart. Some men are experiencing only racial discrimination alone while others are experiencing class discrimination. Women serve the most severe discrimination of them all in the entire country of South Africa. Affirmative action has been used as a tool to eradicate all forms of discrimination. Hence its implementation needs to be evaluated to determine its impact on the eradication of discrimination, more especially sex discrimination. Evaluation has been made possible with the help of affirmative action measures which stipulate most of the principles of the affirmative action directed especially to the employers the gender balancing in the workplace is done with the aim of empowering and advancing women as their right according to gender equality. Women are experiencing the worst kind of social injustice have ever been practiced round the globe. Every woman is experiencing gender discrimination. Even in the rich family women are treated secondary by their male counterpart throughout their history of their living. In actual fact the presence of women in these family units is to help men help the men to have boys who will takeover the patriarchal duties assigned to every men as socialize to think and behave as the head of the families. If the family does not have boys who will later changed to be men, that family previously does run the risk of loosing the rights every households have where there are men. These girls to overcome the barriers of not having men and loose the right mention above they will marry men who will protect the right of their family. Previously, the family that did not have male will run the risk also of being robbed of their land and accused of black magic and the girls being raped. Some of the things that used to happen in the past are happening right now. Although women are promised the full dignity they deserve but some of the worst things that often happen to them in the past are still happening presently owing to the lack of political will to change the patriarchal system which is undermining the full dignity women deserve. This is viewed by Marxist feminists as being caused by the economic mode of production presently operating ‘capitalism’. The Marxist feminist suggests that there shall be no social justice if capitalism is still in place. Therefore they suggested that the only thing to eradicate is to eradicate the present form of production. The liberal feminist claim that the cause of the situation women found themselves is the unequal distribution of resource between men and women. Therefore they advocated that there should be equal rights between men and women as well as equal distribution of resources to men and women. Women must be empowered politically so as to have the equal voice like men. They must emanicipate themselves from the bondages of patriarchal ideologies. Women are just biological different from men but have equal mental capabilities as that of men. The equals should be treated equal and the unequals should be treated unequal. The differences we have should not be made as bases for treating others as unequal. The resources in our societies should be distributed equal among the demographics we have in our societies. The population of the country matters in terms of the countries prestige in terms of economic power. The more the population the country has the more powerful the country will be. In actual fact, the more productive the population of the country is the more productive the country will be. However, the less the productive the population of the country is, the lesser the productivity the country will be. Hence women should also be empowered economically. , Thesis (MMED) -- Faculty of HUMANITIES, SOCIAL SCIENCES and LAW, 2012

The study has been circuits of the Engcobo district. Questionnaires were administered over a group of matriculants, English second language teachers and 8 school principals with a variety of questions and interviews on the causes of this failure problem. Based on the study it has been reared through collect data that some teachers have not been workshopped in the current curriculum (NCS) and this somehow affects the learners. Learners from rural areas have a problem in understanding English language. Lack of educational facilities like libraries also have a negative impact in learner’s progress. Learners who came from Junior Secondary Schools to High schools are not ready and this gives High School teachers a big task to mould them to be ready for matric. It is recommended that parental involvement is vital in their children’s education so as to see their progress and to develop the teacher-parent locomotives learners need to be engaged in Educational activities like debates, public speaking, conducting so as to improve their communication skills. Educators should give more writing and reading exercises to learners so as to minimize the number of learners who are unable to write in Matric. , Thesis (MMED) -- Faculty of Educational Sciences, 2013

- Description: The study investigated the factors that lead to the high failure rate of grade 12 learners of the two high schools in the Ngqeleni area of Libode Mega District of the Eastern Cape, South Africa. The study was qualitative in nature; therefore interviews were used as the method of collecting data. Seven SMT members, four parents and four learners were, randomly selected from the two schools in the Ngqeleni area of Libode Mega District. The researcher randomly selected the participants then interviewed them. The researcher used a video recoder as an instrument to record the responses from the participants. To analyse data, the researcher transcribed the interview responses and interpreted them. The main findings of the study showed that the high failure rate was caused by the following factors: over-croweded classes, shortage of teaching and learnin~ materials, lack of parental involvement, teachers' low morale, poor learner discipline, teachers experiencing problems in implementing government policies, work-load and as such teaching becoming stressful. The researcher in his study therefore recommends that the Department of Education plans more workshops for schools to capacitate them. There should be provision for more classrooms and incentives for teachers. , Thesis (MMED) -- Faculty of Educational Sciences, 2019

- Description: Diabetes mellitus is one of the largest and most important public health emergencies of our time that has resulted in human suffering and huge financial implications for organisations, governments and individuals (IDF Atlas, 2015). Furthermore there is growing evidence that a number of employees are overstretched in their work environments and this has resulted in stress and burnout (McCormack and Cotter, 2013). This study investigated the effects of diabetes mellitus on burnout among WSU employees as well as the prevalence of diabetes mellitus and burnout. A mixed method research design using quantitative and qualitative approaches was employed in order to explore the effects of diabetes on burnout as well as the prevalence of diabetes and burnout at WSU. A cross-sectional survey was used to gather quantitative data and semi-structured interviews were used for the qualitative data collection. A total number of 169 participants were involved in this study. This included 154 participants and 15 participants who were selected for the quantitative and qualitative respectively using random sampling technique and purposive sampling method. The quantitative data was analysed using Stata version 13. The study findings indicated that the prevalence of diabetes at WSU was 16% and 57% participants were burned out. It was further found that the majority of participants (58%) who were diabetic also suffered from burnout. The relationship between diabetes and burnout was found to be significant. Qualitative data analysis involved coding data and analysing the emerging themes to form the basis of the findings. The results of the study found an emerging problem of high level of burnout and also a significant number of employees who were diabetic. A combination of these two conditions poses a challenge to the continued uninterrupted functioning of WSU. It is recommended that the university should educate its employees about diabetes and burnout as well as create an environment that promotes healthy lifestyle. A model has been developed that could help deal with diabetes and burnout. , Thesis - Faculty of Health Sciences, 2019

- Description: This dissertation is a report of the study that was conducted in rural and urban periphery schools of Mthatha City within Mthatha Education District in the Eastern Cape, a province of South Africa. The study explored teacher-assessment practices in two selected junior secondary schools. The utmost purpose was to determine the nature of teacher-assessment practices in these junior secondary schools. This study involved mainly a quantitative research design and later supplemented by qualitative research design. The target population was made up of 63 teachers from both schools. Sampling entailed simple random sampling for quantitative approach and purposeful sampling for qualitative. Instrumentation involved questionnaires and focus group interviews to gather data for these two different research paradigms used. The data was analysed by means of SPSS for quantitative and thematically for qualitative. The results of this study from both instruments were crystallized, and indicated that teachers were grappling with difficulty in strategies and procedures of assessment due to an ever changing curriculum and overload of work. The main findings were: assessment based on content knowledge of learners, negative impact of teacher re-deployment on assessment, stress accumulated by various challenges such as overload of work and frequent curriculum changes as well as lack of data organisation and gathering. The recommendations were: workshops and training programmes on assessment to be provided to teachers; teachers should use various information sources for conducting assessment; more teachers need to be recruited for understaffing and overloading problems as well as pragmatic assessment strategies should be used for learners assessment. Teachers should be included in matters of curriculum changes and be exposed to in-service training. , Thesis (MMED) -- Faculty of Educational Sciences, 2014

- Description: Sexuality remains one of the most misinterpreted and misunderstood social concepts. The societal norms have had a role to play. The identification and acceptance of heterosexuality as the only sexual practice has created some misconceptions. Furthermore, the role played by religion has a tremendous influence on how people views sexuality. However, the aim of the study is to investigate the experiences of the LGBTQIA society with special reference to students residing in the OR Tambo district municipality. Social Constructionism and Five Faces of Oppression are theories that underpinned this study. Furthermore, the nature of this research is descriptive and explorative and the methodology utilized in this study correlates to the mentioned research design. Therefore, qualitative research method was adopted in this study. A sample of 15 participants was utilized, and Non-probability sampling procedure was used through snowball sampling. An in-depth interview guide was used for data collection and thematic analysis approach was utilized for the analysis. Findings of the study suggests that there is rife homophobia in the IHL; the students subscribing to heteronormativity have been threatening those who were homosexuals and/or aligning with the LGBTQIA community with physical assault. It further found that they showed resilience and consistency when it came to academic performance. This, they attributed to their urge to “prove the naysers wrong” as they have been told that they will never make it in life because of their sexuality. The study recommends that the university should engage external stakeholders on the decriminalization of homosexuality and that the university should protect their students from all sort of harm. , Thesis (Masters) -- Faculty of Humanities, Social Sciences and Law, 2021

- Description: Abstract text To effectively reduce HIV transmission to newborns requires a reduction of HIV prevalence among pregnant women and a full understanding of its epidemiology. There is however, a literature gap: few recent HIV studies focus on women attending antenatal care in rural areas in South Africa. A Cross-sectional study of women attending antenatal care in four Primary Care facilities was conducted. An interviewer-administered questionnaire to collect information on socio-demographic characteristics and medical history was used. Binomial logistic regression analyses were used to determine factors associated with HIV and to estimate the prevalence ratio (PR). The 95% confidence interval (CI) is used for precision of estimates; p≤0.05 for statistical significance. A total of 343 participants were recruited. Most participants (n = 341 or 99.42%; CI: 97.91 – 99.93) knew their HIV status. The antenatal HIV prevalence was 38.19% (CI: 33.17 – 43.48). Participants older than 40 years were 3.99 and 3.81 times more likely to be HIV positive compared to teenagers (PR = 3.99; CI: 1.11 – 14.30; pstxvalue = 0.034) and those in the 20-29 age group (PR = 3.81; CI: 1.07 – 13.60; pstxvaluevalue = 0.039) respectively; and this was statistically significant. Unemployed participants were 34% (PR = 1.34; CI: 1.16 – 1.55; p-value less than 0.0001) and 41 percent (PR = 1.41; CI: 1.23 – 1.61; p-value less than 0.0001) more likely to be HIV positive when compared to tertiary students and self-employed individuals respectively. The antenatal HIV prevalence remains high and is increasing in this population. However, findings suggest a changing and maturing epidemic. , Thesis (MMED) -- Faculty of Health Sciences, 2019

- Description: The National Department of Education has undergone drastically changes from 1994. This study is about teacher‘s perceptions of the implementation of NCS. This study seeks to reveal the perception, feelings and the beliefs of teachers towards the implementation of the New Curriculum Statement in Mount Fletcher District of Eastern Cape Province. A mixed mode approach was conducted in this study in a form of quantitative and qualitative methods. Stratified random sampling (schools) and purposive sampling was used to draw the participants (teachers) from different High schools in Mt Fletcher. Data was analyzed following this pattern of organizing, transcribing, coding, establishing themes or categories, structuring, findings which paved way for the recommendations of this study and conclusion. The findings of this study reveals that teachers are just shooting in the dark in the sense that few teachers are implementing NCS successfully using their own methods and strategies of teaching and learning with a very limited clear understanding of the policy documents related to NCS principles while most schools and teachers are implementing through trial and error method, policy documents are just ―blue print to them as they received no clarity of them. And above all, teachers are lamenting on systematic, pedagogical and societal challenges that hindering the process of thorough implementation of NCS. Based on the findings the researcher recommends that the National Department of Education must pay attention for the Systemic challenges e.g. thorough training of teachers on methods of teaching and learning so that they can be able to understand the policies and methods of teaching and learning. She also recommends that whenever the NDoE is introducing new reforms on education, advocacy and awareness must reach the level of implementers not the understanding of the delegates. The NDoE again must pay attention to overcrowded classrooms and classes that are not conducive for teaching and learning (poor infrastructure), lack of basic and appropriate learning materials; Societal challenges e.g. Lack of parental support and Pedagogical challenges e.g. inappropriate teaching methods as well as learning and teacher support material, unqualified and under-qualified teachers, inappropriate assessment procedures, lack of support for teachers.

- Description: Colorectal cancer is one of common cancers worldwide. It is the third most diagnosed cancer and the second leading cause of death. The use of 5-fluorouracil (5-FU) alone or in a chemotherapy regime has been the effective treatment of colorectal cancer patients. The efficacy of 5-FU in colorectal cancer treatment is significantly limited by drug resistance, gastrointestinal, and bone marrow toxicity through high-level expression of thymidylate synthase, justifying a need to improve its therapeutic index. Liposomes are colloidal membranes comprising of one or more lipid bilayers enclosing an aqueous core. They have been used to improve the therapeutic index of many anti-cancer drugs by changing drug absorption, elongating biological half-life, reducing metabolism, and reducing toxicity to healthy tissues. Echogenic liposomes are specifically designed to respond to external triggering like ultrasound stimulation by entrapping a gas or an emulsion that can vaporize. A liposome's unique property is that it can entrap both hydrophobic and hydrophilic substances simultaneously in the lipid bilayer and the aqueous core, respectively. These stimuli-responsive liposomes can be triggered externally with ultrasound, to release the chemotherapeutic cargo only at the required site. This research aims to formulate echogenic liposomes encapsulating 5-FU for potential ultrasound triggered release (echogenic). Liposome formulations wereprepared with lipid composition of crude soybean lecithin and cholesterol by thin-filmhydration method and the drug was passively loaded in the formulation. The 5-FU loadedliposomes were evaluated by dynamic light scattering (DLS) for particle size, polydispersityindex, and zeta potential and transmission electron microscopy (TEM) for morphology.Encapsulated liposomal formulations were also evaluated using physicochemical techniquesincluding thermogravimetric analysis (TGA), differential scanning calorimetry (DSC),Fourier-transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). Theencapsulation efficiency and release kinetics were studied using a validated high-performanceliquid chromatography (HPLC) method. Echogenic properties were explored by entrapping abiocompatible gas (argon) at the same time as the drug (5-FU) using a pressure/freezemethodology. The liposomal formulations were typically spherical with a size of about 150 nmand encapsulation efficiency of 62%. Low-frequency ultrasound (20 kHz) was used to triggerthe drug release from the complete formulation at 10%, 15%, and 20% amplitude and exposuretime of 5 min and 10 min. The rate of drug release from the nano-carrier was a function of theultrasound amplitude and exposure time and reached a maximum of 65% release under theconditions investigated. The cumulative release was investigated, with and without theapplication of ultrasound. It was demonstrated that the application of ultrasound resulted in complete release (99%) after 12 h while this dropped to 70% without ultrasound. These results are encouraging for optimizing ultrasound parameters for triggered and controlled release of the 5-FU, for conditions such as the management of cancer where low-power ultrasound can be applied. , Thesis (MSc) -- Faculty of Science, Chemistry, 2021

- Description: Abstract text. 5.1 Background Paracetamol (acetaminophen) is useful for the treatment of mild to moderate pain as well as being opiate–sparing. In recent years the problem of poor solubility of paracetamol in water has been overcome and an intravenous formulation of paracetamol developed. In South Africa this is marketed by Bristol-Myers Squibb as Perfalgan®. Each 500 mg or 1g ampoule of Perfalgan® is recommended for single use only and is to be discarded once opened (Medicines.org, n.d.). This is most likely due to concerns about degradation of paracetamol or other ingredients in the solution once exposed to air and sterility issues. However in South Africa where this drug is expensive, some centers use one ampoule for multiple cases over the course of 12-24 hours. No obvious clinical adverse effects have been reported. 5.2 Objective of study The aim of this study was to examine the practice of using a single vial of Perfalgan® in divided doses over the course of a day for different patients by way of assessing the stability of Perfalgan® on exposure to air. The study has three components, namely: 1. In vitro assessment of paracetamol levels on exposure to air and stressors over time. 2. In vitro assessment of levels of the excipients, namely mannitol and cysteine on exposure to air and stressors over time. 3. Assessment of the lipid permeability of paracetamol in Perfalgan® on exposure to air and stressors over time. C Curran 2014 Degradation of paracetamol and other constituents in Perfalgan® 8 5.3 Methodology High performance liquid chromatography (HPCL-UV) was used to determine the concentration of paracetamol and the presence of degradation products in samples taken at set time periods following exposure of Perfalgan® to air and stressors. Initial work was done using pure paracetamol to determine optimal measurement conditions prior to analysing Perfalgan®. The concentrations of the additives and their degradation products were measured using nuclear magnetic resonance (1 H NMR). Appreciable changes in these could indicate a safety hazard or decreased bioavailability. Finally ultraviolet spectroscopy was performed to assess samples at a wider spectrum of wavelengths, instead of the single wavelength used in HPLC. This was used to assess for degradation products which absorb at different wavelengths and therefore may be missed if HPLC was used alone. Ultraviolet spectroscopy was also used to test bioavailability of the drug via the octanol:water partition coefficient under stressed and unstressed conditions. 5.4 Results The paracetamol in Perfalgan® did not degrade on exposure to air over 24 hours. Neither did it degrade on exposure to acid, alkali, oxidative or heat stress. The HPLC retention time was constantly between 3.17-3.29 minutes. 1 H NMR revealed no change in the formulation of Perfalgan® except for the conversion of the oxygen scavenger cysteine to cystine. The octanol:water partition coefficient likewise stayed constant and was in agreement with the value of 0.46-0.49 quoted in the literature (International Programme on Chemical Safety, 2008; McNeil Consumer Healthcare, 2010). 5.5 Conclusion The paracetamol in Perfalgan® did not degrade on exposure to air and other stressors over 24 hours. The formulation as Perfalgan® was likewise found to be stable. The drug retained its lipid permeability over this period. , Thesis (MMED) -- Faculty of Health Sciences, 2014

Initial work was done using pure paracetamol to determine optimal measurement conditions prior to analysing Perfalgan®. The concentrations of the additives and their degradation products were measured using nuclear magnetic resonance (1 H NMR). Appreciable changes in these could indicate a safety hazard or decreased bioavailability. Finally ultraviolet spectroscopy was performed to assess samples at a wider spectrum of wavelengths, instead of the single wavelength used in HPLC. This was used to assess for degradation products which absorb at different wavelengths and therefore may be missed if HPLC was used alone. Ultraviolet spectroscopy was also used to test bioavailability of the drug via the octanol:water partition coefficient under stressed and unstressed conditions. 5.4 Results The paracetamol in Perfalgan® did not degrade on exposure to air over 24 hours. Neither did it degrade on exposure to acid, alkali, oxidative or heat stress. The HPLC retention time was constantly between 3.17-3.29 minutes. 1 H NMR revealed no change in the formulation of Perfalgan® except for the conversion of the oxygen scavenger cysteine to cystine. The octanol:water partition coefficient likewise stayed constant and was in agreement with the value of 0.46-0.49 quoted in the literature (International Programme on Chemical Safety, 2008; McNeil Consumer Healthcare, 2010). 5.5 Conclusion The paracetamol in Perfalgan® did not degrade on exposure to air and other stressors over 24 hours. The formulation as Perfalgan® was likewise found to be stable. The drug retained its lipid permeability over this period. , Thesis (MMED) -- Faculty of Health Sciences, 2014

- Description: The motivation for this study is that Health Resource Centres of the Eastern Cape ought to provide access to high quality, relevant and appropriate information that is evidence-based and responsive to the needs of health professionals thereby assisting health professionals accomplish their tasks. In order to provide access to quality information, the Health Resource Centres are expected to provide information services within an acceptable framework of service standards. This study seeks to explore the implementation of standards in the Health Resource Centres of the Eastern Cape. The study was carried out in two phases namely a literature review and a survey. The study used the quantitative method of collecting data by means of a cross-sectional survey. A self administered questionnaire was used to collect data. The questionnaire was piloted in the Queenstown Health Resource Centre, after which appropriate changes were made before the commencement of data collection. The study was conducted in the three other Health Resource Centres of the Eastern Cape, namely Umtata Health Resource Centre, East London Health Resource Centre and Port Elizabeth Health Resource Centre. Health Resource Centre managers completed the questionnaires. The overall findings of this study show that the three Health Resource Centres uphold service standards. The results show that the Health Resource Centres were compliant with the service standards relating to both services and management areas. The Health Resource Centres were more compliant with standards relating to service areas than they were to standards relating to management areas. The results of the study furthermore demonstrate that the Umtata Health Resource Centre was most compliant regarding service areas (86,20%) compared to the East London Health Resource Centre (82,75%) and the Port Elizabeth Health Resource Centre (72,41%). In regard to management areas, the results show that the Umtata Health Resource Centre and East London Health Resource were more compliant than the Port Elizabeth Health Resource Centre. However certain aspects of their service such as availability of space, health and safety, staff performance and development, quality leadership and design and financial management need further attention. The study suggests that further research is required to objectively verify implementation of standards, to solicit health professionals’ opinions and experiences about the services provided by these Health Resource Centres and to find out if there is any connection between the quality of services provided and the quality of patient care. , Thesis (MSc) -- Faculty of Health Sciences, 2015

- 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.

- Description: Abstract text The study investigated the factors that lead to the high failure rate of grade 12 learners of the two high schools in the Ngqeleni area of Libode Mega District of the Eastern Cape, South Africa. The study was qualitative in nature; therefore interviews were used as the method of collecting data. Seven SMT members, four parents and four learners were, randomly selected from the two schools in the Ngqeleni area of Libode Mega District. The researcher randomly selected the participants then interviewed them. The researcher used a video recoder as an instrument to record the responses from the participants. To analyse data, the researcher transcribed the interview responses and interpreted them. The main findings of the study showed that the high failure rate was caused by the following factors: over-croweded classes, shortage of teaching and learnin~ materials, lack of parental involvement, teachers' low morale, poor learner discipline, teachers experiencing problems in implementing government policies, work-load and as such teaching becoming stressful. The researcher in his study therefore recommends that the Department of Education plans more workshops for schools to capacitate them. There should be provision for more classrooms and incentives for teachers.

- Description: Background: Medical doctors in South Africa are required to complete a two-year internship at training hospitals, including a four-month rotation in obstetrics and gynaecology. Following this, doctors are allocated to community service posts; many of which are at district and primary level facilities where supervision is limited. The latest triennial Saving Mothers Report identified district hospitals as the second leading site for maternal deaths of all causes. District hospital were also the leading site for maternal deaths secondary to obstetric haemorrhage and the most likely site for the lack of a skilled doctor to be identified as a factor in deaths associated with caesarean delivery. Methods: This cross-sectional descriptive study aimed to describe the self-perceived readiness of medical interns completing their training to independently manage obstetric emergencies, based on the ESMOE modules in the HPCSA internship logbook. The research assessed medical interns in the last three months of their training, using a self-administered online questionnaire, with data collection between October and December 2019. Cluster sampling of interns at training facilities throughout the country resulted in a total of 182 respondents from 17 hospitals in seven provinces in the country, with an overall response rate of 34.1%. Results: Most interns had experience with, and confidence in, the management of miscarriage and hypertension in pregnancy. However, gaps in labour ward management, pregnancy related sepsis and surgical skills were identified. Only 42.3% of respondents were confident in their ability to diagnose obstructed labour, 26.3% had performed an assisted delivery, 39.0% were confident in their knowledge of the indications and contraindications of assisted deliveries and 35.7% had been involved in the delivery of a baby with shoulder dystocia. Regarding pregnancy related sepsis, 54.4% had experience with managing a wound abscess and 29.7% were confident managing puerperal endometritis. While 78.0% felt confident to perform a caesarean section, only 28.6% had performed uterine compression sutures for uterine atony at caesarean section. Additionally, there was a statistically significant variation in scores between training hospitals. Conclusion: A gap exists between the shortcomings in district hospital obstetric services, the prioritisation of placement of community service doctors at primary care and district hospitals, and the self-perceived readiness of medical interns completing their training to safely manage obstetric emergencies. This highlights the importance of clinical support for junior doctors at district hospitals and standardisation of intern training at accredited facilities across the country. , Thesis (Masters) -- Faculty of Health Sciences, 2021

- Description: This is a comparative study of parental involvement in the governance of public and private schools in the Matatiele District of the Eastern Cape Province of South Africa. Parental involvement can range from occasional attendance of the school functions to partnership through parent teacher organizations and parent management bodies. Education is a national enterprise that requires the co-operation and participation of all the role players who are parents, community, teachers, learners and the Department of Education. The problem to be investigated in this study is: Why is it that parental involvement is more positive in the governance of private schools than that of public schools? Two schools were selected for the study and the researcher administered questionnaires personally by hand and conducted face to face interviews to collect the primary data. The responses of the administered questionnaire were tabulated and recorded in table form so as to give an accurate interpretation of what was revealed in the data. Patterns in the data were considered in order to provide an accurate interpretation of the information. The findings were divided into two, that is: findings from the public school and those from private schools. From the public school it was found that: parents are not involved in the governance of the school; the school does not involve parents on financial matters; parents do not attend meetings when invited; they do not know their roles and responsibilities, for example, according to the South African Schools Act (SASA), parents must be actively involved in the governance of the school in their community and that there is an element of ignorance and negligence on the part of parents towards their children’s education. From the private schools it was found that: parents are more involved in the governance of the school; they attend and participate actively in school meetings; the school involves parents in financial matters and as such the financial support from the parents is very good; parents are much involved in the monitoring of the progress of their learner’s education and are passionate about the school and seem to own the policies and the governance of the whole school system. The conclusion drawn from the study is that private schools allow for parental involvement in the governance of their schools whereas in public schools parental involvement is low. , Thesis (MMED) -- Faculty of Educational Sciences, 2011

- Description: The study aimed to explore and describe the clinical experiences of newly qualified professional nurses in hospital facilities of the Alfred Nzo District Municipality in the Eastern Cape. The newly qualified professional nurses may face difficulties in the hospital facilities when it comes to the execution of duties. The newly qualified professional nurses are expected to display knowledge, skills and to have a positive effect on patients, the relatives of patients and their colleagues to alleviate diseases. This challenge may create emotional distress if newly qualified professional nurses receive inadequate guidance from the senior staff members of the hospital facility. The objectives of this study were to explore and describe the clinical experiences of newly qualified professional nurses, to explore how the newly qualified professional nurses were affected emotionally by clinical experiences and to explore the support system to enhance the performance of the newly qualified professional nurses. A qualitative, explorative, descriptive and contextual design was used to explore and describe the experiences of the newly qualified professional nurses in hospital facilities of the Alfred Nzo District Municipality in the Eastern Cape. A purposive sampling of newly qualified professional nurses, with less than two years of experience after completing the community service in the clinical practice, was used. The data were collected through face-to-face and semi-structured interviews. The interviews were conducted until the data were saturated. A pilot study was done before the main study to prove the adequacy and suitability of the methods to conduct the main study. The participants‟ interviews and results of the pilot study were incorporated into the interviews and results of the main study. Tesch‟s method of thematic analysis and an independent coder were used to analyse the data and to draw meaning from the content. The study used Guba and Lincoln‟s criteria of measures to ensure trustworthiness, which included credibility, confirmability, dependability and transferability. Ethical standards were maintained throughout the study as the researcher complied with ethical principles, namely, respect for persons, beneficence, justice and autonomy. The key considerations to curb the spread of the Covid-19 pandemic, as stipulated by the World Health Organisation, were followed during the data collection. On data interpretation, three themes were developed with eight subthemes on the first theme, two subthemes on the second theme and three subthemes on the third theme. The research findings revealed that the participants experienced negative attitudes from colleagues and multidisciplinary team members. The shortage of staff and resources made participants feel ineffective in their work environment. Clinical exposure to different units and procedures in various units added value to the development of the participants. The recommendations were made with regards to three divisions. They were the hospital facilities‟ personnel, future nursing research personnel and nursing schools personnel. In hospital facilities, the recommendations included that all novice professional nurses should be made aware of the emotional impact at work. An annual plan for workshops and in-service training should be implemented. Professional counselling is required for the novice professionals who were exposed to Covid-19 isolation units. A need to increase staff coverage in the clinical units was identified as the workload is too big. Management is encouraged to be more sensitive about the newly employed nurses‟ challenges in their facilities and the most experienced nurses are encouraged to mentor and coach the novice nurses. In the future nursing research, recommendations included that more studies need to be conducted in South Africa and the Eastern Cape province to verify the findings of this research. A specific research study that will focus on the supportive needs of nurses in clinical facilities should be done institutionally to provide evidence-based practice. The research culture on the nurses‟ experiences in clinical facilities needs to become a norm. In nursing schools, the recommendations motivated that the nursing students should be exposed to all clinical units before completing the training xiv course. Further studies need to be conducted to evaluate the balance between theory and clinical learning on duly performance. The nursing education institutions should use quality improvement suggestion boxes for students to consider their experiences and opinions about their learning.

Public concern over the teaching of reading has mounted in response to inflammatory statements and articles in popular media across the world. According to a statement in South African teachers’ newsletter about 35% of the children in public schools of this country were reported to have reading difficulties. Even the South African Minister for Basic Education, Angie Motshega, in her public statement on grade 12 results in 2010, mentioned reading as the major problem leading to high failure rate. Being a language teacher the researcher in this study believes every learner can read and write on completion of Foundation Phase Level in our schools and that every teacher can help learners with reading and writing difficulties. This study aims to identify the strategies that help teachers to be able to teach reading effectively and efficiently. This study will be of great value to the society at large. Teachers will benefit from this study as various teaching strategies to teach reading will be exposed. The main focus of this study was to explore the factors contributing towards efficient, effective and successful reading of learners in a well-resourced classroom and well equipped teacher. Foundation Phase is where learners acquire the most important skills for lifelong learning. The reading program is a necessity for every public school. A qualitative investigation was undertaken with the purpose to expose the strategies that help teachers in Nelson Mandela Schools (NMS). The study was undertaken in two schools that are in the reading program under the Nelson Mandela Institute (NMI) . The schools were conveniently sampled as the researcher is in one of the schools, so as to obtain easy access. The principals of the two schools and the Foundation Phase teachers were identified as the participants since the program is focusing mainly in the phase. Qualitative data were collected through questionnaires and semi-structured interviews. The outcomes pointed out that parental involvement in their children’s learning is seen as a major contributing factor in learners reading and writing efficiency. The well resourced classrooms and well equipped teachers are also contributing. , Thesis (MMED) -- Faculty of Educational Sciences, 2012
