- Description: The purpose of the study was to scrutinise and assess the effects of South African school’s rationalization framework on educator morale in the Eastern Cape Department of Basic Education amidst the research objectives. The researcher wanted to establish if the Department of Education had succeeded in the implementation of the policy. In terms of the accomplishment of the objectives the researcher wanted to determine whether the exercise of the policy had affected the morale of educators. The study reviewed the literature, theoretical and empirical assessment of rationalisation process on the morale of educators in the King William’s Town district in the Eastern Cape. The study adopted a case study design of qualitative approach. The target population of the study included seventeen educators of the five schools in King William’s Town. A purposive sampling was used to select the respondents. A semi – structured interviews and questionnaires was used, and data was analysed using thematic approach according to the themes from the research questions. The questionnaire method succeeded by interviews was used for the collection of data. The tables and bar graphs were used to represent the number of respondents that participated in the study. The findings denoted that some of the educators believed the Department of Education had not planned the process of rationalisation sufficiently as it brought about anxiety and stress, though some of the affected educators mentioned that it brought relief as there are additional educators to teach other learning areas. The study recommended that the Department of basic Education in Eastern Cape should as a matter of priority provide maximum support to the affected educators. The study concluded that it became evident that the interaction with the respondents showed that the rationalisation process affects redeployed educators negatively. The outcome of the study could be helpful to the Department of Education to come up with strategies of implementing the policy and serve as a centre of reference towards other organisations and unions. , Thesis (MPA) -- University of Fort Hare, 2021

- Description: Environmental Education (EE) is essential for addressing environmental challenges.The advantages of EE are undeniable; it might be used to address specific environmental concerns and their implications, as well as to modify behaviours that lead to environmental catastrophes.EE strengthens people's resilience to climaterelated hazards. Global environmental issues have heightened interest in educational policy outcomes and their implications for economic growth and social citizenship. It is worth noting that an effective EE policy has a significant influence on the development of learners' environmental literacy. This study assessed the implementation of environmental education school policy in the Buffalo City Metro Education District, South Africa. This study adopted the pragmatism paradigm of Mixed Method Research(MMR). Concurrent triangulation, which is a design that employs a single data collection technique in which quantitative and qualitative data gathering and analysis are carried out independently yet concurrently, was used for this study. The target population of this study involved 60,412 teachers, 1,770,289 learners in 5205 public schools, and 1 Pro-EE civil society organisation in the Eastern Cape province. This was narrowed down to over 268 public and independent schools, teachers, and principals within the enclave of the Buffalo Metropolitan education district. The study adopted stratified purposeful and simple random probability sampling. In this technique, the sampling frame of the study was divided into strata or groups (principals, teachers, learners, and CSOs) and a sample was purposefully selected from each stratum (Migiro & Magangi, 2011). The stratified purposeful random sampling techniques draw data from 10 principals, 175 teachers, 1500 learners, and 1 CSO. Structured questionnaire; Implementation of EE Policy Questionnaire (IEEPQ) whose reliability co-efficient value using Cronbach Alpha was 0.74, semi-structured interview and documents were the instruments used to collect data for this study. The data were analysed using descriptive statistics of percentage, mean, and standard deviation for the quantitative data while the thematic approach of sorting, coding, transcribing, and categorization was used for the qualitative data. The study revealed the following. When asked whether teachers had studied environmental education in tertiary institutions as part of their professional training, the majority of the teachers'respondents, 108, representing 61.7percent, disagreed with this view. On the flip side, a handful of teachers 67, (38.3percent) agreed with the view of having had some sort of EE knowledge during their professional training as teachers. With regards to the view that learners learn environmental issues through other subjects, most of the learner respondents, 1316 representing 87.7percent, agreed with this view. On the contrary, a minority of the respondents 184 (12,3percent) had a dissenting opinion. This indicates that most learners in school learn about environmental concerns through other traditional subjects. The study established that EE content is manifest in teachers' and learners' textbooks, teaching methods, and co-curricular activities. However, the study identified lapses in how teachers and learners integrate EE into their day-to-day practices. Therefore, the implementation of the EE policy seems to be an exercise in futility. The absence of a policy guideline document has made teachers and school administrators incapacitated in the implementation of EE school policy. , Thesis (PhD) -- Faculty of Education, 2022

- Description: Implementing the Primary Agriculture curriculum has been a matter of concern for South African TVET colleges due to the high number of students who fail to complete the programmes. This study assessed how Primary Agriculture curriculum is implemented in one rural based TVET college in the in the Eastern Cape Province in South Africa. The study specifically sought to 1) determine the resources available for teaching primary agriculture, 2) teaching approaches adopted by the lecturers, 3) professional skills of staff and 4) how the curriculum was monitored. The study adopted a qualitative approach and case study design of one rural based TVET College. All participants who took part in the study were purposively selected. Data were collected through document analysis of policy and curriculum documents, face-to-face in-depth interviews with 6 college managers and 6 primary agriculture lecturers. Also 20 learners from different academic levels participated in focus group discussions. Findings of the study revealed that there were inadequate teaching and learning resources and this negatively influenced the practical learning aspect of the curriculum. Inadequate resources were caused by delayed procurement processes as well as funding constraints. Students were sent to neighbouring farms and institutions for practical work to curb resource limitations. This caused learning deficiencies as student resource ratios were high thus forcing some students to observe rather than do practical. The study also found limited lecturer professional capacity in pedagogy negatively influenced curriculum delivery. While all the lecturers possessed tertiary qualifications in related fields in agriculture, the majority lacked professional teaching qualifications and pedagogical competences, thus struggled to be creative in using diverse teaching methods to enhance students’ learning outcomes. Even though some staff had to undergo Assessor and Moderator training paid by the college, as part of professional development, this staff development approach was viewed by lecturers as inadequate to improve primary agriculture curriculum implementation. The study also found that curriculum support structures in the college took many forms such as literature or materials on Subject Guidelines, Integrated Summative Assessment Task (ISAT), Internal Continuous Assessment Guidelines, textbooks and sometimes funds to take learners out on field and moderation of students work. The study found that monitoring of the curriculum implementation was weak because various errors made by lecturers in their lesson planning and students Portfolios of Assessment went uncorrected despite it being expressly stated by the moderators that corrections had to be made. The study recommends strengthening partnerships between TVET colleges and the private sector businesses and other public institutions such as the Sector Education and Training Authorities so as to improve the quantity and quality of learning resources and exposure of both staff and students. Also there is need to ensure speedy procurement and delivery of learning resources. In addition, Workplace-Based Exposures (WBE) for lecturers could enhance knowledge on developments of the industry so as to align their teaching methods emerging industry needs. The Department of Higher Education and training could consider fast-tracking strategies to enhance professional capacity of lecturers to allow them to effectively deliver the primary agriculture curriculum. , Thesis (M.Ed) -- Faculty of Education, 2016

- Description: In South Africa different species, from the genus Crataegus, including Crataegus monogyna Jacq and C. mexicana DC have been introduced for various reasons in the past. Populations of these plants have now established in multiple provinces. However, the invasive status, risk and insect pollinators that promote their reproduction and dispersal have never been studied in South Africa. This study was aimed at 1) Assessing the risk of, and mapping two Crataegus species, Crataegus monogyna Jacq and C. mexicana DC in South Africa, 2) Determining the role and effectiveness of insects pollinators to fruiting of C. monogyna and C. mexicana, 3) Identifying flower visitors of C. monogyna and C. mexicana, and 4) documenting potential dispersal vectors for both species in the Eastern Cape Province. A framework entitled “Framework and guideline for conducting risk analysis under NEM: BA Alien and Invasive Species Regulation of 2014” was used to assess the risk of the two Crataegus spp, and we conducted field trips to various provinces in SA to map their distribution. The author conducted an exclusion experiment to determine the role and effectiveness of insect pollinators. Observations were conducted to identify flower visitors and potential dispersal vectors for both species. The risk analysis results suggested that both species pose a high risk of becoming invasive in South Africa. The eradication feasibility of both species was found to be medium with C. monogyna having an eradication feasibility score of 5 and C. mexicana having an eradication feasibility score of 4. This meant that there was a 50 percent chance for both species to be eradicated in South Africa currently. After a thorough risk analysis, it was recommended that both species be listed under category 1b on the National Environmental Management Biodiversity Act. Category 1b species are invasive species that need to be controlled, and if possible, they must be eradicated, trading of species from this category is not allowed. Crataegus mexicana was found to be widespread in South Africa with ten relatively small populations distributed in 5 provinces; Limpopo, Mpumalanga, KwaZulu-Natal, Free State and Eastern Cape Province. Crataegus monogyna was found not to be widespread in South Africa, with only three populations found in the Eastern Cape Province. Insect pollinators contribute to the fruiting of both species in SA. However, the exotic plants were also observed to be able to self-pollinate when insects are excluded. Flowers of C. monogyna were visited by various insect species from orders Lepidoptera, Hymenoptera, Coleoptera and Diptera, while C. mexicana is visited by species from the order Hymenoptera, Diptera, Lepidoptera and Coleoptera. Seventy-seven percent (77 percent) of potential dispersal vectors observed for C. monogyna were birds, and 15 percent were mammals. For C. mexicana, 71 percent of potential dispersal vectors observed were mammals, and 29 percent were birds. Crataegus monogyna and C. mexicana are emerging invasive alien species in South Africa, and not much is known about them. Although the two species are listed as invasive weeds in South Africa, very little is known about their invasive status in other parts of the world. This study has managed to give baseline information and data about both species which are already in South Africa. The baseline information and data include the population structure of both species, their distribution, the risk they pose to South Africa biodiversity and their reproduction ecology. Currently, there are no management plans in place for both species in South Africa, and this is because they are not listed yet in the National Environmental Management Biodiversity Act of South Africa. However, this study recommends that current populations continue to be monitored, awareness of both species in various provinces be initiated to help in the discovery of new and emerging populations, and management options of large populations developed in the future. , Thesis (MSc) (Entomology) -- University of Fort Hare, 2021

- Description: Invasive alien plants (IAPs) are introduced species that constitute a self-sustaining population, consistently producing offspring in large numbers and at considerable distances from the parent plants with the potential to spread over a large area. Species invasions are one of the main conservation threats today and have caused modification of ecosystems, particularly in coastal areas. Therefore, Port St Johns Local Municipality (PSJ LM) was an appropriate study site to evaluate the local awareness and perceptions of IAPs. The study investigated the local community’s perceptions of invasive alien plants' uses and ecological impacts. Information about the local awareness and perceptions of invasive alien plant species in PSJ LM was gathered through semi-structured interviews, observation and guided field walks with 120 participants between February and April 2021. The participants included 30 people working on the alien plant eradication project in PSJ LM (Wards 1, 2 and 3) and 90 randomly selected community members. The data collected were entered in Microsoft Excel 2016 programme and analyzed for descriptive statistical patterns using Statistical Package for Social Studies (SPSS) version 22.0. Biological invasion by IAPs was ubiquitously perceived, with participants working on invasive alien plant eradication project in the area exhibiting more scientifically based knowledge on IAPs than ordinary community members. Invasive alien plants in the area appear to have adverse environmental and socio-economic impacts, as the participants are not benefiting from these plant species. Similarly, costs of eradicating these species were also acknowledged. The ability of local community members to identify IAPs is vital in effective management of the spread of these species. A total of seven invasive IAPs were recorded. Evaluating the perceptions of local people towards IAPs provides valuable insights for development planning and future management programmes focusing on biological invasions. The study will provide a basis for an enabling policy and institutional environment that provides a coherent framework for the sustainable management of IAPs in the Eastern Cape Province. , Thesis (MPhil) -- Faculty of Science and Agriculture, 2021

- Description: Research evidence points to the fact that in most countries teacher educators enter the field of teacher education with little or no preparation (Abell, 1997;Ntoyi≤fuka, 2001; Robinson & Macmillan, 2006; Snoek, Swennen and van der Klink, 2009). Yet, it is argued that the teacher is the single most important factor determining the achievement of learners and the quality of education (UNESCO, 2008; Snoek, Swennen and van der Klink, 2009; Smith, 2010). Sadly, however, most countries and teacher education institutions have paid little or no attention to the preparation, induction and professional development of those who train these teachers, that is, the teacher of the teachers or the teacher educators (Martinez, 2008; Santoro, Mayer, Mitchell, & White, 2009; European Commission, 2010; van Velzen, van der Klink, Swennen, Yaffe, 2010). This situation probably arises from the general belief that good school teachers are good teacher educators and therefore there is no need to worry about their preparation, induction and professional development. This is the basis upon which this research is premised. A mixed methods approach was used to research the following questions: • How are teacher educators in Botswana and South Africa inducted and developed as teachers of adults? • How do the teacher educators (in Botswana and South Africa) adjust their teaching practice to cater for the needs of their students who are adults? • What recommendations can be made to improve the preparation, induction and professional development of teacher educators as teachers of adult student teachers? The sites for the study were four institutions (two faculties of education, one located in Botswana and another in South Africa, and two colleges of education located in Botswana). Out of a possible total of 316 teacher educators at the four institutions 128 responded to a close ended questionnaire that required them to indicate their autobiographic details, experiences as teachers and teacher educators, and their preparation, induction and professional development as teacher educators. In addition 12 teacher educators with varying experiences in teacher education were interviewed. The purpose of the interviews was to record the experiences of their preparation, induction and professional development as teacher educators. Furthermore, literature from various sources was consulted about the topic under study. The results confirmed the earlier assertion that there is very little attention paid to the preparation, induction and professional development of teacher educators in the institutions that were studied. Literature also indicated a similar pattern in most teacher education institutions in Botswana and South Africa. Based on the findings, it is recommended that the preparation, induction and professional development of teacher educators be conducted following the andragogical model. , Thesis (PhD) -- Faculty of Education, 2015

- Description: Research evidence points to the fact that in most countries teacher educators enter the field of teacher education with little or no preparation (Abell, 1997;Ntoyi≤fuka, 2001; Robinson & Macmillan, 2006; Snoek, Swennen and van der Klink, 2009). Yet, it is argued that the teacher is the single most important factor determining the achievement of learners and the quality of education (UNESCO, 2008; Snoek, Swennen and van der Klink, 2009; Smith, 2010). Sadly, however, most countries and teacher education institutions have paid little or no attention to the preparation, induction and professional development of those who train these teachers, that is, the teacher of the teachers or the teacher educators (Martinez, 2008; Santoro, Mayer, Mitchell, & White, 2009; European Commission, 2010; van Velzen, van der Klink, Swennen, Yaffe, 2010). This situation probably arises from the general belief that good school teachers are good teacher educators and therefore there is no need to worry about their preparation, induction and professional development. This is the basis upon which this research is premised. A mixed methods approach was used to research the following questions: • How are teacher educators in Botswana and South Africa inducted and developed as teachers of adults? • How do the teacher educators (in Botswana and South Africa) adjust their teaching practice to cater for the needs of their students who are adults? • What recommendations can be made to improve the preparation, induction and professional development of teacher educators as teachers of adult student teachers? The sites for the study were four institutions (two faculties of education, one located in Botswana and another in South Africa, and two colleges of education located in Botswana). Out of a possible total of 316 teacher educators at the four institutions 128 responded to a close ended questionnaire that required them to indicate their autobiographic details, experiences as teachers and teacher educators, and their preparation, induction and professional development as teacher educators. In addition 12 teacher educators with varying experiences in teacher education were interviewed. The purpose of the interviews was to record the experiences of their preparation, induction and professional development as teacher educators. Furthermore, literature from various sources was consulted about the topic under study. The results confirmed the earlier assertion that there is very little attention paid to the preparation, induction and professional development of teacher educators in the institutions that were studied. Literature also indicated a similar pattern in most teacher education institutions in Botswana and South Africa. Based on the findings, it is recommended that the preparation, induction and professional development of teacher educators be conducted following the andragogical model. , Thesis (PhD) -- Faculty of Education, 2015

- Description: The antibacterial potency of the extracts of the seed of Garcinia kola (bitter kola) was investigated in this study against a panel of referenced, environmental and clinical bacterial strains. The killing rates of the active extract as well as their potential for combination antibacterial therapy with standard antibiotics were also elucidated using standard procedures. The aqueous and acetone extracts of the seed were screened for activity against 27 bacterial isolates. The aqueous extract exhibited activity mainly against Gram positive organisms with Minimum inhibitory concentration (MIC) values ranging from 5 mgml-1 – 20 mgml-1, while the acetone extract showed activity against both Gram negative and Gram positive organisms with MIC values ranging from 10 mgml-1 - 0.156 mgml-1. The acetone extract also showed rapid bactericidal activity against Staphylococcus aureus ATCC 6538 with a 3.097 Log10 reduction in counts within 4 hours at 0.3125 mgml-1 and a 1.582 Log10 reduction against Proteus vulgaris CSIR 0030 at 5 mgml-1 after 1 hour. In addition, the aqueous, methanol and acetone extracts of the seeds also exhibited activity against four clinical strains of Staphylococcus isolated from wound sepsis specimens. The MIC values for the aqueous extract were 10 mgml-1 for all the isolates while the acetone and methanol extracts had lower values ranging from 0.3125 - 0.625 mgml-1. The acetone extract was strongly bactericidal against Staphylococcus aureus OKOH3 resulting in a 2.70 Log10 reduction in counts at 1.25 mgml-1 within 4 hours of exposure and a complete elimination of the organism after 8 hours. The bactericidal activity of the same extract against Staphylococcus aureus OKOH1 was weak, achieving only a 2.92 Log10 reduction in counts at 1.25 mgml-1 (4× MIC) in 24 hours. In the test for interactions between the acetone extract of the seeds and antibiotics, synergistic interactions were observed largely against Gram positive organisms using the FIC indices, (indices of 0.52 - 0.875) with combinations against Gram negatives yielding largely antagonistic interactions (indices of 2.0 to 5.0). Synergy (≥ 1000 times or ≥ 3 Log10 potentiation of the bactericidal activity) against both Gram negative and Gram positive organisms was detected by time kill assays mainly involving the antibiotics tetracycline, chloramphenicol, amoxycillin and penicillin G. Combinations involving erythromycin and ciprofloxacin consistently gave antagonistic or indifferent interactions. We conclude that the acetone extract of Garcinia kola seeds possess strong bactericidal activities against both Gram positive and Gram negative organisms and can be therapeutically useful in the treatment of bacterial infections including the problematic staphylococcal wound infections. In addition, the acetone extract can be a potential source of broad spectrum resistance modifying compounds that can potentially improve the performance of antibiotics in the treatment of drug resistant infections. , Thesis (MSc)-- Microbiology, University of Fort Hare, 2007

- Description: Antibacterial potency of the extracts of the three marine actinomycetes strains which were isolated in the Nahoon Beach and tentatively identified as the genera Norcadia, Kibdellosporingium and Saccharopolyspora were investigated in this study against a panel of referenced, environmental and clinical bacterial strains. The ethyl acetate extracts of these marine actinomycetes were screened for activity against 32 bacterial isolates. Out of the 32 organisms, 10 were susceptible to one or all the extracts used. Antibacterial activity was mainly observed against Gram-negative organisms with Minimum inhibitory concentration (MIC) values ranging from 0.078 mg/ml to >10mg/ml. The killing rates of the active extracts were also elucidated using standard procedures. The two extracts NO64 and NO53 showed rapid bactericidal activity against B. pumilus ATCC 14884 and Serratia marcens with a 3Log10 reduction in counts within 6 hours at 3.75 mg/ml and 5 mg/ml respectively. In conclusion, the ethyl acetate extract of these marine actinomycetes strains possess strong bactericidal and bacteriostatic activities against Gram negative organisms and can be therapeutically useful in the treatment of bacterial infections which are mainly caused by Gram negative bacteria. , Thesis (MA) -- Faculty of Science and Agriculture, 2010

- Description: Background Medical equipment assumes a major part in diagnosis, prevention and treatment of diseases as well as illness and rehabilitation of patients. The maintenance of medical equipment is one of the most vital components in quality health care service delivery and it should not be ignored in the hospital. Therefore, it is critical that medical equipment must be maintained, and be in good working condition to ensure it completes its life cycle, also to prevent possible injuries to the patients and clinicians/end-users. Proper maintenance of medical equipment needs compliance with the manufacturer’s recommendations. Inappropriate maintenance of medical equipment leads to medical equipment malfunctioning, decreases the level of medical equipment performance, and wastes money and other resources. The equipment downtime makes health care services not accessible to patients. Maintenance includes the following activities, medical equipment acceptance, preventive maintenance, inspection, calibration and repair following the manufacturer’s recommendations. Aim of the study The purpose of the study was to assess compliance to the maintenance procedures of medical equipment in a selected hospital in Oliver Reginald Tambo District, Eastern Cape Province. Methodology A qualitative descriptive design was used to access information regarding compliance with the maintenance of medical equipment in a selected hospital, in Oliver Reginald Tambo District, Eastern Cape. The compliance was accessed at the selected hospital that has eight departments. The research objectives gave a framework for how the research was to be conducted. The data was collected through semi-structured interviews until data saturation. An open coding Tesch’s qualitative method was used for data analysis. A purposive sampling technique was used to select participants who were knowledgeable and responsible for management of medical equipment maintenance. The participants were experienced clinicians and technicians answerable for medical equipment maintenance and management. The researcher adhered to ethical and trustworthiness principles. Findings The following themes and their related categories emerged as compliance procedures adhered to/applied: i) Determinants of applied procedures; ii) Compliance with maintenance that is facilitate frequent checks, daily regular testing of equipment; iii) Report faulty equipment; iv) Send equipment for repairs; v) Do follow up on repairs; and vi) Keep machines working all the time. Contributory factors to non-compliance included: Unavailability of funds; technical staff shortage; lack of technical training; non-compliance in performance of quality checks; lack of training of end users; lack of set of maintenance plans; and long procurement process. Complications aligned with non-compliance: Inappropriate referral patients; inaccessibility of health care services; and misdiagnosing patients. Recommendations The strengthening of clinical engineering department with human resources (technical staff), finance (funds for spare parts) and physical resources (workspace, testing equipment and tools, service manuals etc.) Prioritise medical equipment maintenance also improvement of maintenance budget allocation and utilization. Provision of training for end users and technical staff. Establishment and implementation of maintenance plan and improvement of procurement processes. Conclusion The selected hospital is partially compliant with the maintenance of medical equipment because the hospital performs only reactive maintenance. It evidently appeared that affected service delivery is initiated by the shortage of technical staff and equipment availability and reliability. The hospital needs to focus and improve on the above mentioned factors affecting medical equipment maintenance. The results showed that improper maintenance of medical equipment contributes to the overcrowding of tertiary hospitals through unnecessary referrals due to medical equipment malfunctioning. The study contributes to improving the maintenance management of medical equipment. , Thesis (MPH) -- Faculty of Health Sciences, 2021

- Description: This research centres on the holistic assessments of spatial and temporal dimensions of soil erosion zones based on the parameters of geomorphometry, hydro-statistics, and land use/cover dynamics. The study used a case study approach based on a clustered framework model of soil erosion parameters in the Tyume River basin in Eastern Cape, South Africa. The methods adopted for the investigation are, namely; non-parametric time-series assessment of streamflow dataset, semidecadal assessment of land use/cover (LU/C) dynamics, geospatial analysis of geomorphometric variables, vulnerability analysis of soil erosion zones, regression analysis of determination coefficient, and Receiver Operating Characteristic Curve (ROC). The delineation of soil erosion zones was based on the integrated analysis of the parameters of geomorphometry, geology, hydrology, and land use/ cover. The result of the hydro-statistical analysis of the Tyume River reports a major decline in the inter-annual regime frequency of storm flow based on the Mann- Kendall (MK) test and Sen’s slope assessment in 1992 (p-value = 0.031), 1997 (p-value = 0.045), 2003 (p-value = 0.021), 2008 (p-value = 0.003), and 2016 (p-value = 0.002). The MK test depicted a recurrence of peak streamflow acceleration in every three years based on low-flow and highflow transition. The sensitivity of LU/C to temporal dynamics of streamflow trends shown by the coefficient of correlation of trends of the LU/C water bodies with streamflow semi-decadal acceleration indicates a moderately relevant relationship, R = 0.76. The temporal analysis of LU/C and hydro-statistical analysis shows that the Tyume basin was highly vulnerable to soil erosion by water in 1999, 2009, and 2019. The vulnerability of the Tyume River basin in 2019 is exceptional and this is due to the conversion of forested area (woodland) into a built-up environment and farmland, with a high vulnerability in 2019 due to the slump in the rate of change of woodland and precipitation, and the increase in the rate of built-up and agricultural activities. The soil erosion vulnerability mapping divides the river basin into the critical high, high, moderate, low, nonvulnerable zones that cover 40 km2, 135 km2, 209 km2, and 186 km2 respectively. Regression analysis shows that the areas of soil erosion in the Tyume basin are moderately represented by the model (R2 = 56) while the model performance assessment based on success rate and prediction rate estimation from the area under the ROC curve shows that the model is good, Area Under Curve of the ROC = 0.899, and 0.897. The analysis suggests that soil erosion is driven by the impact of land use/land cover change, particularly in areas of high drainage density. Significantly, high vegetation density played a vital role in lowering high-flow on the hill-slope and low topographic wetness area as well as in areas with erodible geologic properties. The study, therefore, recommends the advocacy of crop rotation method of agricultural practice in the highly critical areas of soil erosion and recommends the development of riparian forests around the Tyume River. The study provides important information for environmental stakeholders on degradable areas which may require the urgent implementation of sustainable development measures. , Thesis (MPhil) -- Faculty of Science and Agriculture, 2022

- Description: Impacts associated with climate variability and extreme heat are already obvious in varying degrees and expected to be disruptive in the near future across the globe especially in the urban regions. Urban areas have distinctive features that leave their residents and properties vulnerable to extreme climate events. Global temperatures continue to change, reaching new levels almost every year for the past two decades. However, even though the causes are debated it is evident that climate variability is real. Climate variability and disaster risk are threats to human health that adversely reinforce each other. Better knowledge on the association between climate change, variability and extreme weather-related illness is needed and can aid strategies to reduce vulnerabilities. The impacts of climate variability on the health of residents in East London (EL) area in the Eastern Cape Province, South Africa were explored through four interdependent research segments. The first section examined the climate variability and urban surface thermal characteristics implication on human health using Remote Sensing (RS) and Geographic Information System (GIS) techniques. Remote sensing was used to assess the Land Surface Temperature (LST) and estimated Radiation (R) of East London area from Landsat Thematic Mapper (TM) images for 1986, 1996, 2006 as well as from Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) for 2016 spanning a period of 30 years. Rapid urbanization and land cover changes in this area have contributed significantly to this drastic change in the natural land surface characteristics (increased land surface temperature and surface solar radiation). For instance, vegetation cover declined by about 358.812km2 while built-up areas increased by 175.473km2 during this period which correlates with the area thermal characteristics changes. Radiation levels also increased over the years with values exceeding the global solar radiation index. Exposure to increased surface radiation poses risks of heat stroke, skin cancer and heart disease to the local population. Consequently, this study provides pertinent information on human health sustainability and epidemiological case management. The second part explored past temperature and humidity trends (1986-2016) and projects future trends (2017-2030). The historical data of meteorological variables were obtained from the archives of the South African Weather Service and analyzed using the ordinary least square regression model in GRETL (GNU Regression Econometric and Time-series Library) statistical software. This study discovered a local consistency between models and the observations add to existing knowledge and this is crucial in knowing the shifts in climatic change as well as recognizing variability and its conflicting effects on human health, environment, agriculture, ecological sustainability and socioeconomic status in the region. The third segment assessed the potential impacts of climate variability on health using existing heat indices during the study period. The results demonstrated that in East London from 1986 to 2016 during summer and autumn (December to May) of various years exceeded high heat index values. It is obvious that summer and autumn months are more vulnerable to heat extreme and humidex. The humidex and Heat Index (HI) increased annually by 0.03 percent and 0.9 percent respectively throughout the study period. The increment in the various indices showed highly significant ill-health and environmental impacts on humans especially with prolonged exposure. The last segment appraised the association between climatic elements and epidemiological incidences of the study area between 2012 and 2016. The epidemiology incidences data were obtained from the archives of the Cecilia Makiwane Hospital in East London area and National Tertiary Service Grant (NTSG) database for the period. The results have showed that there exists significant effects of climate variability on the health of East London residents and these have been identified to have negative impacts on health of the people in the area. This study also revealed noticeable impacts of extreme heat on human health and a positive correlation between meteorological components (HI and temperature) and epidemiological cases (cardiovascular, skin cancer and diarrhea) during the study period. , Thesis (PhD) (Geography) -- University of Fort Hare, 2018

Rapid urbanization and land cover changes in this area have contributed significantly to this drastic change in the natural land surface characteristics (increased land surface temperature and surface solar radiation). For instance, vegetation cover declined by about 358.812km2 while built-up areas increased by 175.473km2 during this period which correlates with the area thermal characteristics changes. Radiation levels also increased over the years with values exceeding the global solar radiation index. Exposure to increased surface radiation poses risks of heat stroke, skin cancer and heart disease to the local population. Consequently, this study provides pertinent information on human health sustainability and epidemiological case management. The second part explored past temperature and humidity trends (1986-2016) and projects future trends (2017-2030). The historical data of meteorological variables were obtained from the archives of the South African Weather Service and analyzed using the ordinary least square regression model in GRETL (GNU Regression Econometric and Time-series Library) statistical software. This study discovered a local consistency between models and the observations add to existing knowledge and this is crucial in knowing the shifts in climatic change as well as recognizing variability and its conflicting effects on human health, environment, agriculture, ecological sustainability and socioeconomic status in the region. The third segment assessed the potential impacts of climate variability on health using existing heat indices during the study period. The results demonstrated that in East London from 1986 to 2016 during summer and autumn (December to May) of various years exceeded high heat index values. It is obvious that summer and autumn months are more vulnerable to heat extreme and humidex. The humidex and Heat Index (HI) increased annually by 0.03 percent and 0.9 percent respectively throughout the study period. The increment in the various indices showed highly significant ill-health and environmental impacts on humans especially with prolonged exposure. The last segment appraised the association between climatic elements and epidemiological incidences of the study area between 2012 and 2016. The epidemiology incidences data were obtained from the archives of the Cecilia Makiwane Hospital in East London area and National Tertiary Service Grant (NTSG) database for the period. The results have showed that there exists significant effects of climate variability on the health of East London residents and these have been identified to have negative impacts on health of the people in the area. This study also revealed noticeable impacts of extreme heat on human health and a positive correlation between meteorological components (HI and temperature) and epidemiological cases (cardiovascular, skin cancer and diarrhea) during the study period. , Thesis (PhD) (Geography) -- University of Fort Hare, 2018

- Description: Impacts associated with climate variability and extreme heat are already obvious in varying degrees and expected to be disruptive in the near future across the globe especially in the urban regions. Urban areas have distinctive features that leave their residents and properties vulnerable to extreme climate events. Global temperatures continue to change, reaching new levels almost every year for the past two decades. However, even though the causes are debated it is evident that climate variability is real. Climate variability and disaster risk are threats to human health that adversely reinforce each other. Better knowledge on the association between climate change, variability and extreme weather-related illness is needed and can aid strategies to reduce vulnerabilities. The impacts of climate variability on the health of residents in East London (EL) area in the Eastern Cape Province, South Africa were explored through four interdependent research segments.

- Description: The intention of this study was to assess the implementation of performance management system at the Mnquma local municipality. The municipality of Mnquma has in the past been plagued by service delivery challenges and thus the study sought to ascertain whether the challenges could be attributed to the failures of the performance management system within the municipality. It became apparent from the literature review that for any local municipality to play a meaningful role in ensuring that South Africa achieves the goal of becoming a developmental state, capable of confronting service delivery challenges, there needs to be a proper implementation of the performance management system. The study was also aimed at identifying the factors that support or hinder the implementation of the performance management system within the Mnquma local municipality. In order to achieve this objective, scheduled interviews were conducted with various respondents in the municipality. The respondents included the councilors from the four political parties comprising the municipality council, municipal manager and the rest of the Section 57 managers. The key findings that emerged from the data collected, was that the implementation of the performance management system has not been successful. It is also became apparent that there are brewing political tensions that are likely to affect the political stability of the municipality. In addition, it was also evident that there was a minimal or lack of involvement of the local communities in the municipal affairs such as the development of the Municipal Key Performance Indicators. It would therefore be critical important for the management of the Mnquma local municipality to take into account the results of this study and its recommendations so as to ensure that there is a proper implementation of the performance management system within the municipality. , Thesis (MPA) -- Faculty of Management and Commerce, 2008

- Description: The massive campaign by Zimbabwe to educate all children was achieved through the education for all policy. When quantity had been achieved more focus was on quality issues. The quality concerns coincided with market-based developments which compelled Zimbabwe to adopt change reforms such as the teacher performance appraisal, one of which focused on quality teaching strategies that would enhance learners’ quality academic achievement. Nevertheless since its inception in 1996 and subsequent implementation in 2000, teachers through their unions have challenged the use of the appraisal which quantifies the teacher’s work, alleging their work cannot be atomized into separate elements to be measured, weighed and then ticked off. The contention highlighted above prompted the need for a research to be carried out which sought to assess: How is the performance appraisal system being implemented in the primary schools? A mixed methods design which is located in the postpositivist paradigm which produced in-depth, detailed, rich data from personal perspectives and experiences that resulted in realistic understanding, interpreted through the social and cultural context of the respondent’s lives. Educators resisted the imported system alleging it was imposed on them without adaptation to local environment. Lack of pilot-testing of the system, lack of proper training and lack of a meaningful reward system perverted the system to a mere ritual that frustrated implementers who found it difficult to use it in their daily work. The study recommends the following: That the educators be incorporated in designing an appraisal system that encompasses the whole teacher’s work package which is geared towards teaching the whole child. That there be a more efficient and sustainable reward system. That the system be interwoven into supervisory mechanisms so that there is no demarcation between the appraisal and daily supervision. , Thesis (PhD) -- Faculty of Education, 2012

- Description: The bioflocculant-producing potentials of three marine bacteria isolated from the sediment samples of Algoa Bay in the Eastern Cape Province of South Africa were assessed. Analysis of the partial nucleotide sequence of the 16S rDNA of the bacteria revealed 99 percent, 99 percent, and 98 percent similarity to Cobetia sp. L222, Bacillus sp. A-5A, and Bacillus sp. HXG-C1 respectively and the sequence was deposited in GenBank as Cobetia sp. OAUIFE, Bacillus sp. MAYA and Bacillus sp. Gilbert (accession number JF799092, JF799093, and HQ537128 respectively). Cultivation condition studies for Cobetia sp. OAUIFE revealed that bioflocculant production was optimal with an inoculum size of 2 percent (v/v), initial pH of 6.0, Mn2+ as the metal ion, and glucose as the carbon source. Metal ions, including Na+, K+, Li+, Ca2+and Mg2+ stimulated bioflocculant production resulting in flocculating activity of above 90 percent. This crude bioflocculant is thermally stable, with about 78 percent of its flocculating activity remaining after heating at 100 oC for 25 min. Analysis of the purified bioflocculant revealed it to be an acidic extracellular polysaccharide. FTIR analysis revealed the presence of methoxyl, hydroxyl, and carboxyl - groups in the compound bioflocculant and SEM micrograph of the bioflocculant revealed a crystal-linear structure. On the other hand, bioflocculant production by Bacillus sp. MAYA was optimal when glucose (95.6 percent flocculating activity) and ammonium nitrate (83.3 percent flocculating activity) were used as carbon and nitrogen sources respectively; inoculum size was 2 percent (v/v); initial pH 6; and Ca2+ as coagulant aid. Chemical analysis of the purified bioflocculant shows that it is composed of uronic acid, neutral sugar and protein. FTIR analysis also revealed the presence of methoxyl, hydroxyl, carboxyl and amino- groups in this bioflocculant. The bioflocculant is thermostable with about 65.6 percent residual flocculating activity retained after heating the bioflocculant at 100 oC for 25 min. However bioflocculant production by Bacillus sp. Gilbert was optimal when sodium carbonate (95.2 percent flocculating activity) and potassium nitrate (76.6 percent flocculating activity) were used as carbon and nitrogen sources respectively; inoculum size was 3 percent (v/v); initial pH 9; and Al3+ as cation. The crude bioflocculant retained 44.2 percent residual flocculating activity after heating at 100 oC for 15 min. FTIR analysis reveals the presence of hydroxyl, carboxyl and methylene - groups in the compound bioflocculant. SEM micrograph of the bioflocculant revealed an amorphous compound. The consortia of these bacteria strains also produced bioflocculants with high flocculating activities which were highly efficient in removing turbidity and chemical oxygen demand (COD) from brewery wastewater, diary wastewater and river water. The bioflocculants from the consortia seemed better than traditional flocculants such as alum . The characteristics of the bioflocculant produced by the consortium of Cobetia sp. OAUIFE and Bacillus sp. MAYA showed that this extracellular bioflocculant, composed of 66percent uronic acid and 31percent protein and an optimum flocculation (90 percent) of kaolin suspension, when the dosage concentration was 0.8 mg/ml, under weak alkaline pH of 8, and Ca2+ as a coagulant aid. The bioflocculant is thermally stable, with a high residual flocculating activity of 86.7 percent, 89.3 percent and 87.0 percent after heating at 50 oC, 80 oC and 100 oC for 25 min respectively. The FTIR analysis of the bioflocculant indicated the presence of hydroxyl, amino, carbonyl and carboxyl functional groups. Scanning electron microscopy (SEM) image revealed a crystal-linear spongy-like bioflocculant structure and EDX analysis of the purified bioflocculant showed that the elemental composition in mass proportion of C,N,O,S and P was 6.67:6.23:37.55:0.38:4.42 (percent w/w). However, the characteristics of the bioflocculant produced by the consortium of Cobetia sp OAUIFE and Bacillus sp. Gilbert showed an optimum flocculation (90 percent) of kaolin suspension when the dosage concentration was 0.2 mg/ml, under neutral pH of 7, and Ca2+ as a coagulant aid. The FTIR analysis of the bioflocculant Tyume River water samples were collected monthly, over a 12-month period starting from August 2010 and ending in July 2011, and transported on ice to the Applied and Environmental Microbiology Research Group (AEMREG) Laboratory at the University of Fort Hare, Alice for analyses within 6 h of collection. Electrical conductivity (EC), total dissolved solids (TDS), temperature, pH and dissolved oxygen (DO) of water samples were determined in situ using a multi-parameter ion-specific meter. Concentrations of orthophosphate and total nitrogen (nitrate + nitrite) were determined by standard photometric methods. Total coliforms (TC), faecal coliforms (FC) and enterococci were determined by the membrane filtration method. Viruses in water samples were concentrated using the adsorption-elution method, followed by extraction of viral nucleic acids and purification done using commercially available kits. The concentrations of human enteric viruses in the river-water samples were estimated using quantitative PCR. RNA viruses were quantified in a two-step protocol where RNA was first transcribed into cDNA in a separate reverse-transcription step. Adenovirus species and serotypes were simultaneously detected using serotype-specific multiplex PCR. Norovirus genogroups GI and GII were detected by semi-nested PCR. The risk of infection associated with recreational and domestic use of the water was also estimated. Biochemical oxygen demand (BOD) levels fell within the stipulated BOD guideline of 10 mg/ℓ for surface waters where full contact use is allowed and ≤ 30 mg/ℓ where public access is prohibited, restricted, or infrequent. DO concentrations generally ranged between 7.47 mg/ℓ and 10.42 mg/ℓ, well within the target water quality requirements. The temperature regime ranged between 6°C and 28°C and for most sampling sites, the temperature regimes were within the acceptable limit of no risk (≤ 25°C) for domestic water uses in South Africa. EC ranged between 47 μS/cm and 408 μS/cm well within the South African target water quality EC guideline of 700 μS/cm though it was observed to increase as the river flowed through settlements. The pH in the period beginning September 2010 through to January 2011 was consistently below pH 9, but from February 2011 to June 2011 the pH significantly increased to between pH 10 and pH 11 at most sampling sites. Unpolluted waters normally show a pH of between 6.5 and 8.5. Most of the pH values observed in this study lie between pH 8.5 and pH 10.8 levels which are not far off from the upper level guideline of pH 9.0 for domestic use. Turbidity ranged between 6 NTU and 281 and fell short of the target water quality range (0 NTU to 1 NTU) of no risk for domestic water uses in South Africa. Monthly TDS values and EC values showed direct proportionality. TDS concentrations at all sites fell within the acceptable guideline of 0 mg/ℓ to 450 mg/ℓ of TDS for domestic use. Nutrient profiles were as follows: nitrate (0.18 mg/ℓ to 4.21 mg/ℓ); nitrite (0.02 mg/ℓ to 2.35 mg/ℓ); and orthophosphate (0.06 mg/ℓ to 2.72 mg/ℓ). The bacteriological qualities of the water were poor, exceeding the guideline of 200 CFU/100 mℓ and 33 CFU/100 mℓ for FC and enterococci respectively, for recreational water. FC counts also exceeded the 1 000 CFU/100 mℓ guideline for water used in fresh produce irrigation. Generally, higher counts of TC, FC and enterococci were recorded at the sampling sites located at the lower reaches of the river compared to the upper reaches. Adenovirus was detected in 31percent of the river samples in concentrations ranging between 1.0×100 genome copies/ℓ and 8.49×104 genome copies/ℓ. Serotyping showed the presence of species C adenovirus serotypes 1, 2, 6 and 7, and species F adenovirus serotype 41. The prevalence of norovirus was 4percent while rotavirus was detected in 4percent of river samples in concentrations ranging between 9×100 genome copies/ℓ and 5.64×103 genome copies/ℓ. Hepatitis A virus was detected in 13percent of river samples in concentrations ranging between1.67×103 and 1.64×104 genome copies/ℓ while enteroviruses were not detected. Detection of enteric viruses was inversely correlated to temperature. Risk analysis showed that both hepatitis A virus and adenovirus presented significantly higher risk of infection values compared to rotavirus in the case of ingestion of 10 mℓ or 100 mℓ of water from Tyume River while enteroviruses did not present any significant risk of infection. Tyume River water samples also did not conform to the US Environmental Protection Agency (US EPA) bacterial criteria of 200 CFU/100 mℓ faecal coliforms and 33 CFU/100 mℓ enterococci for bathing waters. Whereas the physicochemical parameters showed that Tyume River water was relatively clean, the bacteriological water quality was poor. Most of the microbiological contamination observed in this study (especially FIBs) can be blamed on inadequate sanitary infrastructure as we observed that open defecation is commonplace in this catchment, which also serves as a conduit for effluent discharges from wastewater-treatment facilities. Enteric viruses were detected along the course of the river in a sporadic pattern, generally not related to natural hydrological cycles and so we conclude that the presence of enteric viruses in the river is suggestive of the dynamics of the same in the host population. Even though the proportion of infective viruses was estimated in this study, fact remains that there is considerable risk of infection posed by the use of raw surface water for either domestic or recreational use. This study further confirmed the lack of correlation between faecal indicator bacteria and enteric virus occurrence in environmental waters, showing that assaying for enteric viruses in environmental waters remains the best method for determining the health risks associated with the use of faecally contaminated water. , Thesis (PhD) -- Faculty of Science and Agriculture, 2013

The crude bioflocculant retained 44.2 percent residual flocculating activity after heating at 100 oC for 15 min. FTIR analysis reveals the presence of hydroxyl, carboxyl and methylene - groups in the compound bioflocculant. SEM micrograph of the bioflocculant revealed an amorphous compound. The consortia of these bacteria strains also produced bioflocculants with high flocculating activities which were highly efficient in removing turbidity and chemical oxygen demand (COD) from brewery wastewater, diary wastewater and river water. The bioflocculants from the consortia seemed better than traditional flocculants such as alum . The characteristics of the bioflocculant produced by the consortium of Cobetia sp. OAUIFE and Bacillus sp. MAYA showed that this extracellular bioflocculant, composed of 66percent uronic acid and 31percent protein and an optimum flocculation (90 percent) of kaolin suspension, when the dosage concentration was 0.8 mg/ml, under weak alkaline pH of 8, and Ca2+ as a coagulant aid. The bioflocculant is thermally stable, with a high residual flocculating activity of 86.7 percent, 89.3 percent and 87.0 percent after heating at 50 oC, 80 oC and 100 oC for 25 min respectively. The FTIR analysis of the bioflocculant indicated the presence of hydroxyl, amino, carbonyl and carboxyl functional groups. Scanning electron microscopy (SEM) image revealed a crystal-linear spongy-like bioflocculant structure and EDX analysis of the purified bioflocculant showed that the elemental composition in mass proportion of C,N,O,S and P was 6.67:6.23:37.55:0.38:4.42 (percent w/w). However, the characteristics of the bioflocculant produced by the consortium of Cobetia sp OAUIFE and Bacillus sp. Gilbert showed an optimum flocculation (90 percent) of kaolin suspension when the dosage concentration was 0.2 mg/ml, under neutral pH of 7, and Ca2+ as a coagulant aid. The FTIR analysis of the bioflocculant Tyume River water samples were collected monthly, over a 12-month period starting from August 2010 and ending in July 2011, and transported on ice to the Applied and Environmental Microbiology Research Group (AEMREG) Laboratory at the University of Fort Hare, Alice for analyses within 6 h of collection. Electrical conductivity (EC), total dissolved solids (TDS), temperature, pH and dissolved oxygen (DO) of water samples were determined in situ using a multi-parameter ion-specific meter. Concentrations of orthophosphate and total nitrogen (nitrate + nitrite) were determined by standard photometric methods. Total coliforms (TC), faecal coliforms (FC) and enterococci were determined by the membrane filtration method. Viruses in water samples were concentrated using the adsorption-elution method, followed by extraction of viral nucleic acids and purification done using commercially available kits. The concentrations of human enteric viruses in the river-water samples were estimated using quantitative PCR. RNA viruses were quantified in a two-step protocol where RNA was first transcribed into cDNA in a separate reverse-transcription step. Adenovirus species and serotypes were simultaneously detected using serotype-specific multiplex PCR. Norovirus genogroups GI and GII were detected by semi-nested PCR. The risk of infection associated with recreational and domestic use of the water was also estimated. Biochemical oxygen demand (BOD) levels fell within the stipulated BOD guideline of 10 mg/ℓ for surface waters where full contact use is allowed and ≤ 30 mg/ℓ where public access is prohibited, restricted, or infrequent. DO concentrations generally ranged between 7.47 mg/ℓ and 10.42 mg/ℓ, well within the target water quality requirements. The temperature regime ranged between 6°C and 28°C and for most sampling sites, the temperature regimes were within the acceptable limit of no risk (≤ 25°C) for domestic water uses in South Africa. EC ranged between 47 μS/cm and 408 μS/cm well within the South African target water quality EC guideline of 700 μS/cm though it was observed to increase as the river flowed through settlements. The pH in the period beginning September 2010 through to January 2011 was consistently below pH 9, but from February 2011 to June 2011 the pH significantly increased to between pH 10 and pH 11 at most sampling sites. Unpolluted waters normally show a pH of between 6.5 and 8.5. Most of the pH values observed in this study lie between pH 8.5 and pH 10.8 levels which are not far off from the upper level guideline of pH 9.0 for domestic use. Turbidity ranged between 6 NTU and 281 and fell short of the target water quality range (0 NTU to 1 NTU) of no risk for domestic water uses in South Africa. Monthly TDS values and EC values showed direct proportionality. TDS concentrations at all sites fell within the acceptable guideline of 0 mg/ℓ to 450 mg/ℓ of TDS for domestic use. Nutrient profiles were as follows: nitrate (0.18 mg/ℓ to 4.21 mg/ℓ); nitrite (0.02 mg/ℓ to 2.35 mg/ℓ); and orthophosphate (0.06 mg/ℓ to 2.72 mg/ℓ). The bacteriological qualities of the water were poor, exceeding the guideline of 200 CFU/100 mℓ and 33 CFU/100 mℓ for FC and enterococci respectively, for recreational water. FC counts also exceeded the 1 000 CFU/100 mℓ guideline for water used in fresh produce irrigation. Generally, higher counts of TC, FC and enterococci were recorded at the sampling sites located at the lower reaches of the river compared to the upper reaches. Adenovirus was detected in 31percent of the river samples in concentrations ranging between 1.0×100 genome copies/ℓ and 8.49×104 genome copies/ℓ. Serotyping showed the presence of species C adenovirus serotypes 1, 2, 6 and 7, and species F adenovirus serotype 41. The prevalence of norovirus was 4percent while rotavirus was detected in 4percent of river samples in concentrations ranging between 9×100 genome copies/ℓ and 5.64×103 genome copies/ℓ. Hepatitis A virus was detected in 13percent of river samples in concentrations ranging between1.67×103 and 1.64×104 genome copies/ℓ while enteroviruses were not detected. Detection of enteric viruses was inversely correlated to temperature. Risk analysis showed that both hepatitis A virus and adenovirus presented significantly higher risk of infection values compared to rotavirus in the case of ingestion of 10 mℓ or 100 mℓ of water from Tyume River while enteroviruses did not present any significant risk of infection. Tyume River water samples also did not conform to the US Environmental Protection Agency (US EPA) bacterial criteria of 200 CFU/100 mℓ faecal coliforms and 33 CFU/100 mℓ enterococci for bathing waters. Whereas the physicochemical parameters showed that Tyume River water was relatively clean, the bacteriological water quality was poor. Most of the microbiological contamination observed in this study (especially FIBs) can be blamed on inadequate sanitary infrastructure as we observed that open defecation is commonplace in this catchment, which also serves as a conduit for effluent discharges from wastewater-treatment facilities. Enteric viruses were detected along the course of the river in a sporadic pattern, generally not related to natural hydrological cycles and so we conclude that the presence of enteric viruses in the river is suggestive of the dynamics of the same in the host population. Even though the proportion of infective viruses was estimated in this study, fact remains that there is considerable risk of infection posed by the use of raw surface water for either domestic or recreational use. This study further confirmed the lack of correlation between faecal indicator bacteria and enteric virus occurrence in environmental waters, showing that assaying for enteric viruses in environmental waters remains the best method for determining the health risks associated with the use of faecally contaminated water. , Thesis (PhD) -- Faculty of Science and Agriculture, 2013

- Description: This study is located in the field of education, within the domain of Continuing Professional Development CPD and curriculum. The study sought to assess the role of CPD in the transformation of health practice. The media’s complaints about poor service delivery within spheres of government, from local up to national level, triggered interest in a study of this nature. Since the Department of Health falls amongst the essential services, research on current public healthcare with the intention of transforming its practice was seen as imperative. An Advanced Diploma in District Health Management and Leadership ADDHM & L offered by Health Sciences at the University of Fort was used as a case. The healthcare practitioners who attended the stated programme were studied as a second case. The setting is in the public health care centres in the Department of Health within the Amathole region and Nelson Mandela Bay Metropolitan Municipality. An interpretive paradigm was used to ordain the study, the three sets of data were collected from various categories of participants such as graduates of the ADDHM & L programme, their workplace supervisors, as well as the facilitators of the programme. The last set of data was collected from the ADDHM & L documents. Interviews and questionnaires were used as data collection tools and thematic analysis was used for data analysis. The findings revealed that curriculum development and design has a strong bearing on formal continuing professional development programmes. For such programmes to be able to transform practice, the curriculum pedagogies should be designed and developed in such a way that the learning taking place is authentic in nature. It is this type of learning that will influence reflective practice and translation of knowledge. The findings also revealed that institutions of higher learning do play a crucial role in closing the gap that exists between theory and practice through designing programmes that are pedagogically aligned towards authentic learning. The learning instructions, the experiences, the expectations of the learner, the assessment forms that influence the nature of tasks and activities given by facilitators can either enable or hinder the ability to transform practice. , Thesis (PhD) -- Faculty of Education, 2018

- Description: Buffalo River is an important water resource in the Eastern Cape Province of South Africa. Over a 1-year period (August 2010–July 2011), the water quality and incidence of human enteric viruses (HEntVs) was assessed, using standard methods and molecular techniques and a total 72 composite water samples collected monthly from a total of 6 sites located on the river and three dams along its course. The sites were selected based on a number of factors including geographical location, anthropogenic activity/major water use, rural/urban status and access. A total of 13 physicochemical parameters were determined using the standard methods. The counts of faecal indicator bacteria (FIB) including total coliforms (TC), faecal coliforms (FC) and enterococci (ENT) were determined by the membrane filtration technique. HEntVs were concentrated using an adsorption-elution method based on cation (Al3+)-coated membrane filter. Real-time quantitative polymerase chain reaction (qPCR) was used for the detection and quantification of human adenoviruses (HAdV), and real-time reverse transcriptase-PCR (RT-qPCR) was used for the quantitative detection of hepatitis A virus (HAV), human rotaviruses (RoV) and enteroviruses (EnV). The detected HAdV were characterized by multiplex conventional/semi-nested PCR methods. The risks for human health constituted by exposure to the detected HEntVs at the six sites were evaluated by a static quantitative microbial risk assessment (QMRA) using both the exponential and beta-Poisson models. Water temperature ranged from 11 to 28oC, while pH varied from 6.6 to 10.7, and turbidity from 1.7 to 133 NTU. Electrical conductivity (EC), total dissolved solids (TDS) and salinity showed drastic variations (42.3-46693 μS/cm, 20.3–23350 mg/L and 0.02–33.8 PSU respectively). The concentrations of other parameters ranged as follows: chloride (3.7–168 mg/L); DO (6.9–11.1); BOD (0.6–9.4); COD (3.7–45.9); nitrite-nitrogen (0.02–0.21); nitrate-nitrogen (1–4.47); and orthophosphate (0.01–1.72). TC, FC and ENT counts were high and ranged from 1.9 × 102–3.8 × 107 cfu/100 mL, 0–3.0×105 cfu/100 mL and 0–5.3 × 105 cfu/100 mL for TC, FC and ENT respectively. Significantly (P<0.05) higher concentrations of FC and ENT were observed at the sampling sites located at the lower reaches of the river compared to the upper reaches. The FIB counts mostly exceeded the maximum limits recommended by national and international guidelines for safe fresh produce irrigation, domestic applications, full-contact recreation and livestock watering. Significant (P<0.01) positive correlations existed between TDS and salinity (r=0.921), between turbidity and each of TC (r=0.552) and FC (r=0.425), as well as between BOD and each of TC (r=0.282), FC (r=0.472) and ENT (r=0.552). Phosphate correlated positively with FC (r=0.424), and nitrate also with the same, FC (r=0.460). A strong positive correlation existed between FC and ENT (r=0.915). There existed a significant (P˂0.01) inverse correlation between enteric viruses and each of water temperature (r=-0.191) and pH (r=-0.234). No correlation could be deduced between enteric viruses and all the tested chemical and bacteriological parameters. HAV, HAdV, RoV and EnV were detected in 43.1percent, 34.7percent, 13.9percent and 9.7percent respectively of the total 72 water samples tested. Two or more viruses were detected in 22.2 percent of the samples. HAdV were detected at 5 of the 6 sampling sites with concentrations ranging from 1.2×101 genome copies (GC)/litre to 4.71×103 GC/litre. Epidemiologically important serotypes, Ad40/41 constituted 83.3percent, while Ad21 made up 16.7percent of all the HAdV detected. HAV was detected at all the sites in significantly (p < 0.05) varying concentrations that ranged from 1.5 × 101–1.9 × 105 GC/litre compared to RoV and EnV. Neither of RoV nor EnV was detected at any of the dams. The detected concentrations at the non-dam sites ranged from 2.5 × 101–2.1 × 103 GC/litre and 1.3 × 101–8.6 × 101 GC/litre for RoV and EnV respectively. The values for the estimated daily risks of enteric virus infection varied with sites and exposure scenario, and ranged from 7.31×10-3–1 (for HAdV), 4.23×10-2–6.54×10-1 (RoV), 2.32×10-4–1.73×10-1 (HAV) and 1.32×10-4–5.70×10-2 (EnV). The yearly risks of infection in individuals exposed to the river/dam water via drinking, recreational, domestic or irrigational activities were unacceptably high, exceeding the acceptable yearly risk of 0.01percent (10-4 infection/person/year) recommended by the USEPA for drinking water. The risks of illness and of death from infection ranged from 6.58×10-5–5.0×10-1 and 6.58×10-9–5.0×10-5 respectively. Data on the physicochemical and bacteriological parameters showed that the Buffalo River water quality was poor, and deteriorated in the plains compared to the upper reaches. These water quality data, the presence of enteric viruses and the QMRA data, that revealed unacceptably high risks of enteric virus infections, and of illness and mortality from the infections, show that the Buffalo River and its dams are contaminated waters that constitute significant public health hazards. Provision of adequate sanitary infrastructure will help prevent source water contamination, and public health education aimed at improving personal, household and community hygiene is imperative. Monitoring enteric viruses in rivers and source water dams is necessary and useful as a risk assessment tool for the exposed population. Future research should consider a comprehensive characterization of the detected viruses. This work is both a significant contribution to the molecular epidemiology of enteric viruses and the first report on molecular detection and quantification of enteric viruses in surface waters in the Eastern Cape. , Thesis (PhD) -- Faculty of Science and Agriculture, 2013

- Description: The demand for animal products is projected to increase progressively due to extensive urbanization, rapid growth of the human population and income dynamics. The demand for indigenous animal products will increase due to increasing income levels and this will be happening at the time when the supply of indigenous product is reducing as a result urbanization. The purpose of the current study was to assess consumption and willingness to pay for indigenous animal products looking at chicken and pork. The study intended to determine the socio- economic determinants influencing consumer willingness and consumption. Multistage sampling was used to derive a sample of 120 consumers at households. Primary data were collected using a structured interview schedule. Data collected was on household consumer characteristics, responses to different bid levels for indigenous meat and socio-economic determinants. The study used a Contingent Valuation Method to assess consumers‟ mean WTP for indigenous meat and logit model to determine socio-economic determinants influencing consumers‟ WTP. Results indicated that consumers were willing to pay an average premium of 33percent above the current prevailing price of convectional meat. They also showed that about 87percent of consumers who were willing to pay for indigenous meat and about 12.8percent who are willing to pay if the price increases. Of those who were willing a greater proportions were females. About 64percent of those who are willing and aware of indigenous meat most of them obtained information from neighbours and friends, Age, level of education, consumer awareness and monthly household income had a positive and significant effect on WTP. Most of the consumers indicated that indigenous meats are affordable, healthier when compared conventionally-produced meat. The main significant barrier to the purchase of indigenous meat was identified as its limited availability at convenient locations. The study recommends policy intervention aimed at facilitating development of marketing infrastructure, creation of awareness of important nutritional and health benefits of indigenous meat, and boosting the development of animal production systems that can add value to indigenous meat, so as to capture existing market opportunities. This would enhance food security and income generation of the small-scale resource-constrained farmers. , Thesis (MSc) -- Faculty of Science and Agriculture, 2015

- Description: Teacher education has been the focus of numerous studies across the world. The debates revolve around what models or approaches to teacher development produce high quality teachers as measured by their ability to promote student learning. This has given rise to a continuum of models. At the one extreme there are those who advocate practice first and theory later; at the other there are those who recommend theory first and then practice. In between there is a combination of a variety of approaches. The models of teacher development, however, continue to grapple with the problem of how to balance theory and practice. In Malawi, the Ministry of Education, Science and Technology (MoEST) (MIE, 2006) came up with what they see as a balance between theory and practice when they introduced the 1 year of theory and 1 year of practice, a model referred to as the 1+1. The focus of this study was on the one year of practical teaching where mentoring is critical; hence the particular attention to examine and understand how its quality was assured from the perspective of fitness for purpose and fitness of purpose. The study was anchored mainly in the post-positivist paradigm and the methodology used was the mixed-methods approach. A mixed methods sequential explanatory design comprising a survey followed by a case study was employed. For the survey, four sets of semi-structured questionnaires whose Cronbach Alpha Reliability Coefficients, α, were 0.971, 0.827, 0.859 respectively were developed using the Tailored Design Method; these were pilot tested and then administered through a drop-and-pick strategy to a census sample of 804 respondents comprising 92 school mentors, 92 school head-teachers, 4 Teacher Training College mentoring coordinators and 616 student teachers. A total response rate of 96percent was obtained. The case study design phase comprised six one-on-one face-to-face structured interviews; five focus groups; five non-participant observations; and a review of ten documents employing interview schedules, observations and document checklists as instruments for data collection. A total of 27 participants, three of whom did not participate in the survey phase, were involved in this phase. Quantitative data collected from either phase was analyzed using IBM SPSS Statistics 20 while content analysis was used to analyse qualitative data. As a mixed-method study, some of the qualitative data was quantitized and some of the quantitative data was qualititized; and integration of data was made during the following stages: research questions formulation, data collection, data presentation, and discussion and interpretation. The study revealed several weaknesses in assuring the quality of mentoring in the 1+1 IPTE model. First, the norms and standards for mentoring designed by the Ministry of Education were not used to guide the mentoring process. Instead, they were designed to fulfil accountability requirements of the Ministry of Education and Teacher Training Colleges rather than self-improvement. Hence, the study revealed that all the 92 schools had, therefore, no policies, practice codes and standards for monitoring mentoring casting doubt on the functioning of internal quality assurance. The study further revealed that 12 of the school mentors (13percent) had lower academic qualifications than their seventy-two student teachers they were mentoring; 35 of the school mentors (38percent) were at the entry grade of their teaching career; two of the mentors (2percent) (mentoring over twelve student teachers) were within the first three years of teaching, which means that they, themselves, were in need of being mentored; and all the school mentors had full time teaching responsibilities. As such, some student teachers indicated that they were not being assessed at all by their school mentors. This situation regarding mentors raises concerns over the subject knowledge levels of the mentors, the role model functions of the mentors and their competency to effectively mentor student teachers, as well as concerns regarding the quality of the mentoring programme and its outcomes. Findings from the study also revealed little or no monitoring of mentoring in schools as schools had no structures and systems for monitoring mentoring; and heavy workloads and financial constraints prevented college lecturers from monitoring mentoring in primary schools. However, on a positive note, the study revealed that 99percent of school mentors were trained for their mentoring roles and were receiving regular training which was provided regularly on a term-basis. Based on the above findings, the 1+1 Initial Primary Teacher Education model in Malawi is undermined by weak mentoring practices which have the potential to widen the theory and practice gap, and potentially impact on the quality of teachers produced. It is further recommended that the mentoring practices move away from the technicist approach and focus on the actual processes of mentoring; that norms and standards for school mentor selection and support are developed; that there should be more workshopping, seminars and conferences for mentors; and that schools should be assisted to develop collegial-emancipatory quality assurance systems for mentoring. A rainbow model for assuring the quality of mentoring in the 1+1 IPTE mode is finally recommended. , Thesis (PhD) -- Faculty of Education, 2014

- Description: Teacher education has been the focus of numerous studies across the world. The debates revolve around what models or approaches to teacher development produce high quality teachers as measured by their ability to promote student learning. This has given rise to a continuum of models. At the one extreme there are those who advocate practice first and theory later; at the other there are those who recommend theory first and then practice. In between there is a combination of a variety of approaches. The models of teacher development, however, continue to grapple with the problem of how to balance theory and practice. In Malawi, the Ministry of Education, Science and Technology (MoEST) (MIE, 2006) came up with what they see as a balance between theory and practice when they introduced the 1 year of theory and 1 year of practice, a model referred to as the 1+1.

- Description: Although the South African government has drafted policy documents to protect gays, they, year-in-year-out face abhorrence. Notably and shockingly, misunderstanding of the sexual orientation of gays in initiation schools has brought about conflict. It is of great significance for ulwaluko tradition to renegotiate its terms of being a tradition tolerating those with different sexualities within their adored culture. Therefore, this study sought to assess the attitudes of heteronormative traditional male circumcision stakeholders towards an emergence of same-sex sexuality in ulwaluko in Mdantsane and New Brighton, Eastern Cape. The study endeavoured to achieve the following objectives: i to establish the policy insights on same-sex sexuality in South Africa and elsewhere; ii to assess the prevalence of homosexuality in South Africa and other contexts; iii to establish an account of gay men’s intimate behaviour at the initiation schools; iv to examine perceptions and attitudes of selected communities on Xhosa gay men undergoing the rite of traditional male circumcision; v to establish attitudes and perceptions of selected communities on the conflict between homosexual practices and traditional male circumcision TMC and vi to assess perceptions of Xhosa gay men on the use of TMC as an instrument to “convert” them to heterosexuality. The study was informed by Four 4 theoretical lenses: sociocultural theory, anomie theory, queer theory, and intersectionality theory. Methodologically, the objectives were investigated through a qualitative research method and data was collected accordingly. The study adopted a case study as its design. Data was collected through in-depth one-on-one interviews, focus group discussions, and key informants’ interviews. The study purposively selected eighty-two 82 participants and revealed the following findings: different lenses on South African constitution and homosexuality; different attitudinal facets of the development of same-sex sexuality in South Africa, opposed lenses on homosexuality being a natural phenomenon; intimate partner relationships among the gays in the initiation schools; behavioural the difference between gays and heterosexuals in the initiation school; establishing the nature of homosexuals’ dress code; gays downplaying TMC teachings in initiation schools; Intimate partner relationships among gays in the initiation school; homosexuality associated with modernization; effectiveness of TMC as a tool to achieve gays’ heteronormativity; and lastly, gays achieving heteronormativity through rape. This study concluded that TMC needs to renegotiate its terms of being a tradition of the contemporary epoch. Perhaps this may assist in breaking the tension between ulwaluko and same-sex sexuality in society. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2022
