- Description: Cycles - their nature in existence, their implications on human-kind and the study thereof have sparked some important philosophical debates since the very pre-historic days. Notable contributions by famous, genius philosophers, mathematicians, historians and economists such as Pareto, Deulofeu, Danielewski, Kuznets, Kondratiev, Elliot and many others in itself shows how cycles and their study have been deemed important, through the history and process of scientific and philosophical inquiry. Particularly, the explication of Business, Economic and Financial cycles have seen some significant research and policy attention. Nevertheless, most of the methodologies employed in this space are either purely empirical in nature, time series based or the so-called Regime-Switching Markov model popularized in Economics by James Hamilton. In this work, we develop a Statistical, non-linear model fit based on circle geometry which is applicable for the dating of cycles. This study proposes a scalable, smooth and differentiable quarter-circular wavelet basis for the smoothing and dating of business, economic and financial cycles. The dating then necessitates the forecasting of the cyclical patterns in the evolution of business, economic and financial time series. The practical significance of dating and forecasting business and financial cycles cannot be over-emphasized. The use of wavelet decomposition in explaining cycles can be seen as an critical contribution of spectral methods of statistical modelling to finance and economic policy at large. Being a relatively new method, wavelet analysis has seen some great contribution in geophysical modelling. This study endeavours to widen the use and application of frequency-time decomposition to the economic and financial space. Wavelets are localized in both time and frequency, such that there is no loss of the time resolution. The importance of time resolution in dating of cycles is another motivation behind using wavelets. Moreover, the preservation of time resolution in wavelet analysis is a fundamental strength employed in the dating of cycles. , Thesis (DPhil) -- Faculty of Science, Mathematical Statistics, 2019

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

- Description: This study sought to evaluate factors affecting the quality of food provided by the school nutrition programme in Mthatha, OR Tambo Inland Education District. This was a qualitative study in the form of case study research design. Two (2) schools were conveniently selected and from these, 2 principals, 2 school nutrition coordinators, 4 food handlers and 10 learners were purposefully selected to form the sample. Thus, 18 participants were selected in total. Interviews were used to collect data. A review of literature demonstrated that the school nutrition programme was valuable and played an important role towards addressing some of challenges prevalent in South Africa due to the history of the country. The literature reviewed also highlighted challenges faced by the school nutrition programme despite its tremendous success. These are some of the findings: the school nutrition programme was successful towards improving learner punctuality and engaging in the classroom. This had the potential to improve learner health overall; however, it was observed that lack of training around food preparation and hygiene could reduce the effectiveness of the programme. The provision for appropriate storage facilities was also noted as an issue that placed the programme at risk. These are some of the recommendations: the government should provide appropriate training and proper storage facilities in schools with nutrition programme; this could contribute meaningfully towards improving the quality of food provided by the school nutrition programme. , Thesis (M.Ed) -- Faculty of Education Sciences, 2019

- Description: Curriculum change processes in South Africa have been effected since 1994 after the general elections. This was meant to deconstruct the apartheid education curriculum, which was biased against the black majority. A curriculum change strategy is meant to improve the education system. It is also traditional that teachers form an important component of any curriculum change process. In spite of this, teachers have never played a centre stage in any curriculum change process. This study had the objective of investigating the impact of curriculum change on the academic performance of Grade 12 Business Studies learners in the Mthatha Education district of the Eastern Cape Province. The researcher set out to collect data using stratified random sampling design where a school represented a stratum. Two research instruments were constructed for this study. The two instruments were: a questionnaire and an interview schedule. The participants to the two research instruments were selected by random procedure. A random number table was used to select the participants based on a properly laid down statistical mechanism. Ten high schools constituting of 100 Business Studies learners and ten Business Studies teachers were randomly selected to participate. The data were analysed both quantitatively and qualitatively and later merged for common themes. The key findings were: curriculum change having influence on teachers’ and learners’ academic performance and improved availability of resources for teaching and learning. The findings also revealed factors that drive curriculum change and challenges facing curriculum change. Another key finding was the support by the majority of participants in favour of frequent curriculum reviews, an established positive attitude by teachers towards curriculum change and showing skills and sufficient knowledge in the cause of delivering of lessons. These were not influenced by the respondent’s age group. Finally, it was observed that there was dire need for frequent curriculum reviews and institution of learner-centeredness of classroom activities. The recommendations proffered included: Workshops for the professional development of teachers be on going, considering the inevitable continuous change. This should be boosted by incentives in the form of certificates or cash for workshop attendance. There should also be on-going post-training follow-ups and cluster visits by EDOs and Subject Advisors for guidance purposes: regular feedback helps teachers to effectively apply change because help is immediately available. , Thesis (D.Ed) -- Faculty of Education Sciences, 2019

- Description: Green leafy vegetables are important in human nutrition, but their cultivation is limited to a few staple ones. These vegetables possess high nutritious and therapeutic properties that could help in achieving nutritional security and alleviating the burden of some diseases. A typical example is Celosia argentea, which in South Africa, is little known and grossly under-utilized despite its numerous nutritional and pharmacological values. The present study investigated the cultivation, nutritional and pharmacological potentials of C. argentea at three stages of maturity of two trials. Evaluation of cultivation in the greenhouse towards possible domestication of C. argentea included seed viability test, seed germination under varying temperatures (5, 10, 15, 20 25 30, 35, 40°C), light conditions (continuous light, continuous darkness, alternating light and dark (12h light/12 dark photoperiod) and sowing depths (0, 1, 2, 3, 4 and 5cm). The nutritional evaluation assessed the proximal, mineral, vitamins and antinutrient content of the plant; while pharmacological potentials of C. argentea were evaluated by investigating the ultramorphology, phytochemical content, anti-oxidant, antimicrobial, toxicity and cell-based anti-inflammatory properties of the plant at different stages of growth. Germination experiment revealed that optimum seed germination requirements for C. argentea were 25°C, alternating light and dark regime and a sowing depth of 1cm. Microrphological assessment of C. argentea revealed that the leaves were amphistomatic; with the abaxial surface having higher stomata density. Characteristic, distinguishing protuberances were observed at the polar ends of the stomata on the adaxial surface of the plant epidermis, and the major elements on the foliar epidermis were beryllium, carbon, oxygen and potassium; while pigmentation and colouration, showing localization of bioactive compounds were mostly at the site where trichomes were abundant. Growth parameters and yield potential (plant height, stem girth, leaf area, number of leaves, number of branches, number of days to flowering, number of flowers as well as dry and fresh weight) of C. argentea showed that for agricultural practices on the field, increase in growth parameters should be expected around 4-5 weeks after transplanting while higher yield should be expected around 7-9 weeks after transplanting. The results encouraged cultivation during summer or late spring for best farm management. Proximal, mineral, vitamins and anti-nutrients content of C. argentea at three different maturity stages of two trials were performed using AOAC, ALASA and inductively coupled plasma-optical emission spectrometer techniques. Results revealed that the pre-flowering stage of growth had the highest ash (28.15± 0.10 percent) and crude protein (25.80 ± 0.20 percent) contents. While post-flowering stage had the highest carbohydrate (28.51± 0.20 percent and 36.16± 0.22 percent), crude fibre (33.41± 0.87 percent) and energy (435.28± 27.6 percent) with low fat and moisture (8.43± 0.15 percent and 6.35±0.09 percent) contents respectively; while no marked demarcation in most mineral contents in all the growth stages was observed. Zinc was highest at the flowering stage of growth, while vitamin contents decreased as the plant approached maturation. Antinutrients content of the plant was not dependent on growth stage. Total phenols, flavonoids and proanthocyanidin content of C. argentea were evaluated colourimetrically, while the antioxidant potency of the aqueous, acetone and methanolic extracts was measured using 2,2 diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) (ABTS), Ferric reducing antioxidant power (FRAP) and total antioxidant capacity (TAC) models. All the solvent extracts of the flowering stage had the highest total phenolic (80.75±4.21GAE/g), flavonoids (946.19±7.87QE/mg) and proanthocyanidin contents (100.90±1.29 CE/g); with the acetone extracts showing significantly higher phytochemical content. The flowering stage exhibited the best radical inhibitory activity, with the methanol extract having the highest scavenging power for ABTS and DPPH radicals, while acetone extract showed the highest inhibition against FRAP and highest total antioxidant capacity. The antimicrobial potential of the aqueous acetone and methanolic extracts of C. argentea evaluated using agar dilution method against six bacteria (Klebsiella pneumonia, Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Bacillus subtilis and Bacillus cereus) and four fungal strains (Candida glabarata, Candida albicans and Penicillium aurantiogriseum and Penicillium chrysogenum) showed that Streptococcus pyrogenes and P. aeruginosa were susceptible to the methanol extracts of all the growing phases of both trials at 10 mg/mL; while Klebsiella pneumoniae was susceptible at 10 mg/mL to only the methanol post-flowering extracts of both trials. C. albicans and P. aurantiogriseum were highly susceptible to all the extracts. Possible toxicity evaluated using brine shrimp lethality assay and calculation of LC50 against brine shrimp nauplii revealed that C. argentea was not toxic at any stage of maturity at all concentrations evaluated. Anti-inflammatory activities and cytotoxicity of C. argentea extracts evaluated using RAW 264.7 macrophages and 3T3-L1 cell lines revealed that the acetone extract of the flowering stage had moderate anti-inflammatory activity with no significant toxicity against activated macrophages. Findings from this study indicate that C. argentea is a safe functional leafy vegetable of high nutritional and pharmacological importance which can easily be cultivated and domesticated in South Africa. This could significantly alleviate the burden of micronutrient deficiencies among pre-school children in rural communities. , Thesis (PhD) (Botany) -- University of Fort Hare, 2019

This could significantly alleviate the burden of micronutrient deficiencies among pre-school children in rural communities. , Thesis (PhD) (Botany) -- University of Fort Hare, 2019

- Description: The purpose of this study was to investigate parents’ and teachers’ perspectives towards the teaching and learning of intellectually impaired learners at Foundation Phase in Mthatha Education Sub-District. This study explored the lived experiences of parents and teachers of intellectually impaired learners in this special school. It determined parents’ and teachers’ understanding of intellectual disability, the challenges they face in working with such children and strategies they use to deal with intellectually challenged learners. The research was limited to one special school in Mthatha, which is the only special school in this sub-district. The study used the qualitative research approach in the form of case study research design. The sample consisted of twelve participants, four parents of learners who are intellectually impaired and eight Foundation Phase teachers in this special school. These are some of the findings: The Education White Paper 6 on building an inclusive education and training is effective even though it is moving slowly. There has been no preparation on how it should be implemented in terms of human and other resources, knowledge and skills on special needs education. The challenges teachers face in teaching learners who are intellectually impaired include: learner-teacher ratio that is not followed, hence overcrowded classes; classroom management; lack of learner support materials; no special curriculum designed for intellectually impaired learners; confining subject matter and teachers not participating in skills development. The mechanism that were suggested to assist learners who are intellectually impaired included: equipping teachers with skills necessary for learning and teaching of intellectually impaired learners, establishing institutional level support teams, making more learning and teaching resources available, providing qualified human resources, mobilizing public support, government understanding impairment and therapists being employed (psychologists, physicians, nurses, doctors and social workers). Some of the recommendations are: conducting workshops on effective coping strategies for teachers, public awareness campaigns in communities about intellectual disability, school governing bodies working with the government to supply the school with adequate learner support materials, proper infrastructure, School Based Support Teams support service, the District taking responsibility for establishing networks that promote effective communication between learners, teachers and parents as well as with non-governmental organizations and welfare, health and justice departments and Supporting teachers on site. , Thesis (M.Ed) -- Faculty of Education Sciences, 2019

- Description: Sweetpotato (Ipomoea batatas L. LAM) is a major world staple food. It is a versatile, nutrient-rich crop well suited for production by emerging farmers, and thus a popular crop in subtropical parts of South Africa. The crop has several advantages such as producing more bioweight and nutrients per unit land area and per unit time than most other staple crops such as maize; adaptation to a broad range of agro-ecological conditions; and ability to compete and crowd out weeds, and affected by a relatively small number of pests and diseases. Root and vine yields achieved by emerging farmers are low and cultivation systems need to be optimized. The general objective of the research was to develop nursery practices that ensure a sustainable supply of sweetpotato planting materials and cultural practices that maximize yield, eating and nutritional quality of sweetpotato roots. The specific objectives were (i) to evaluate the effect of polyethylene and hessian bags on vine quality and vine survival period; (ii) to compare planting techniques and vine length; (iii) to determine the effect of paclobutrazol on storage root yield; and (iv) to evaluate the effect of Beauveria bassiana as biological control for sweetpotato weevil. The vine storage experiment aimed at identifying the best type of storage bags that keep the vines of “Bophelo”, an orange-fleshed sweetpotato cultivar in good quality for a longer period of time. The study involved two factors, viz storage bag type and storage period. The experiment tried to address (1) a sustainable seed system in sweetpotato and (2) production stimulated by cultural practises. Vines were stored in polyethylene bag without holes, polyethylene bag with 12 holes and dry hessian bag over 3, 6, 9, 12 and 15 days at an ambient temperature of 250C. The incremental cost-effectiveness ratio (ICER) was calculated to determine the cost-effectiveness of using the polyethylene bags with holes or without and the hessian bags. The results of the study showed that hessian bags store vines over a longer period (12 days) compared to the polyethylene bags without holes (6 days); however, hessian bags are more expensive. Polyethylene bags can still be used for transporting and storing vines if the farmer is within a short distance from the seed source and plants the vines within the 6 day period. Polyethylene bags with 12 holes are recommended since they allow maximum air circulation and extend storage period (9 days). Optimum planting techniques can help sweetpotato farmers to achieve optimal yields. Newly developed cultivars from the Agricultural Research Council have not been tested to determine the best planting techniques. A trial was conducted to investigate the effect of two planting orientations (horizontal and vertical) and different vine length (2, 3 and 4 subterranean nodes) of 3 released varieties, Blesbock, Bophelo and Ndou on storage root yield of sweetpotato. A factorial experiment was laid out in a randomised complete block design with three replications during two cropping seasons (2014/15 and 2015/16). The data collected in both experiments included total storage root yield, marketable storage root yield, and number of storage roots per size class. Significant differences were detected for the interaction of all factors on the number roots per size class, total storage root yield, and total average root weight. Vertical and horizontal planting per se showed no significance differences for all the sweetpotato root growth parameters such as total yield. However, the more the number of subterainian node the more yield we got for the commercial cultivar Blesbok. Paclobutrazol (PBZ) is a plant growth retardant hormone. This hormone might, therefore, be useful for sweetpotato growers to achieve higher plant populations per hectare because it would reduce the plant canopy. However, it should also be checked if the PBZ application does not affect nutrient content of roots and leaves, especially the beta-carotene content of the orange-fleshed cultivars. The objective of this study was, therefore, to determine the effect of PBZ on sweetpotato shoot growth, storage root yield and beta-carotene content of sweetpotato leaves and storage roots. The field trial was repeated over two seasons, namely 2014/15 and 2015/16 crop seasons. These field experiments were arranged as a split plot experiment. The main plots were allocated to four PBZ levels, laid-out as randomised complete block design, and treatment combinations of two cultivars (Bophelo and Blesbok) and two plants spacing (20 cm and 30 cm) were randomly allocated into the subplots. The PBZ levels applied were 0, 100, 200 and 300 mg of active ingredient per litre of water, sprayed 4 weeks after planting. Root yield and bioweight accumulation were recorded. In addition, a pot experiment was set up using cultivar Bophelo and 0 mg, 100 mg and 200 mg/l active ingredient of PBZ sprayed 4 weeks after planting. Leaf and root samples (150g and 400g of a composite sample respectively) were collected and analysed for total phenols, total flavonoids, vitamin C and beta-carotene. The field trial results revealed significant differences (P<0.05) in leaf and stem weight of the plants treated with different PBZ levels applied. The control (0 mg PBZ rate) had the highest leaf and stem weight. There were no significant differences in root yield among the PBZ levels. The results of leaf and root analysis for the Bophelo cultivar showed significant differences (P<0.05) in total phenols, total flavonoids, vitamin C and beta-carotene in leaf samples of the three levels of PBZ applied. The beta-carotene for the leaf increased at the 100 mg/l PBZ level. As the paclobutrazol level increased there was a reduction in the beta-carotene content for the roots from 18,91 to 13,97 to 10,77 mg/100g dry weight for 0 mg/l, 100 mg/l and 200mg/l, respectively. Application of PBZ to sweetpotato reduces the bioweight yield but does not have an effect on the root yield. Thus a higher plant density can be used to achieve higher yield and returns on investment. The leaves can be used as a relish and can be sold to supplement income. However, PBZ further reduces the beta-carotene content of the roots and is not recommended for use with orange-fleshed cultivars, where the objective is to enrich food with vitamin A. Sweetpotato weevils (Cylas puncticollis and C. formicarius) are notorious pests of sweetpotato. It causes severe losses in marketable root yield. The study tested the use of Beauveria bassiana (Balsamo Vuillemin) (Deuteromycota: Hyphomycetes) for controlling sweetpotato weevils. Experiments were conducted over two cropping seasons using four treatments: 1) dipping sweetpotato cuttings in solution of 1 g/litre B. bassiana before planting, 2) spraying with a registered chemical (Deltametrin) at 50 ml/100 litre of water starting 2 weeks after panting at biweekly basis for four months after planting, 3) spraying the leaves with B. bassiana (10 g/100 litre) starting 2 weeks on biweekly basis for four months after planting; and 4) control (sprayed with water). The research was arranged as split plot experiment, where the pest management treatments assigned to the main plots as per Latin square design and the three sweetpotato cultivars (Bophelo, Ndou and Blesbok) were randomly put in the subplot in each main plot. Spraying with B. bassiana significantly reduced the percentage of insect-damaged roots (9.95percent) compared to the control (22.48percent). Dipping sweetpotato cuttings in solution of 1 g/litre B. bassiana before planting did not significantly reduce the number of insect damaged roots (18.63percent insect damage). There was no significant difference between the chemical spray (8.2percent insect damage) and spraying with B. bassiana (9.95percent insect damage). The investigation indicated that B. bassiana can be considered as an alternative control method for the sweetpotato weevil. Use of biological control is less expensive and beneficial to reduce adverse effects on the environment and human health. , Thesis (PhD) -- Faculty of Science and Agriculture, 2019

- Description: This study evaluates the occurrence of medically relevant Acinetobacter species in three rivers, namely; Keiskamma, Tyhume and Great Fish in the Eastern Cape Province, South Africa in one year sampling regime (April 2017 - March 2018). The physicochemical parameters (pH, temperature (TEM), electrical conductivity (EC), total dissolved solids (TDS), salinity (SAL), total suspended solids (TSS), turbidity (TBS), dissolved oxygen (DO) and biological oxygen demand (BOD)) of the water bodies were measured. The presumptive Acinetobacter species recovered from the freshwater resources were recorded and further confirmed using molecular techniques. Similarly, confirmed isolates were subjected to speciation using species-specific primer sets for A. baumannii and A. nosocomialis. Also, virulence genes namely; afa/draBC, epsA, fimH, OmpA, PAI, sfa/focDE, and traT in the two Acinetobacter species were also determined using molecular method. In addition, the antibiogram characteristics of A. baumannii and A. nosocomialis isolated from the water samples were determined using standard methods. The antibiotic susceptibility test was performed using a panel of 12 antibiotics belonging to the aminoglycosides (amikacin, AK and gentamicin, GM), β-lactam/β-lactamase-inhibitor combinations (piperacillin-tazobactam, PTZ), cephems (ceftazidime, CAZ, cefotaxime, CTX, and cefepime, CPM), carbapenems (imipenem, IMI and meropenem, MEM), fluoroquinolones (ciprofloxacin, CIP), folate pathway inhibitors (Trimethoprim/sulfamethoxazole, TS), lipopeptides (Polymyxin B, PB) and tetracyclines (tetracycline, TET). Similarly, antibiotic resistance genes (ARGs) present in the Acinetobacter isolates were investigated including aminoglycoside resistance genes (aacC2, aphA1 and aphA2), β-lactamases resistance genes (blaTEM, blaSHV, blaOXA-1-like, blaCTX-M(GROUP 1), blaCTX-M(GROUP 2), blaCTX-M(GROUP 9), blaVEB, blaGES, blaPER, blaCTX-M-8/-25, blaOXA-48-like, blaVIM, blaIMP and blaKPC), fluoroquinolones resistance genes (qnrA, qnrB, qnrC, qnrD and qnrS), sulfonamide resistance genes (sul1 and sul2), and tetracycline resistance genes (tetA, tetB, tetC, tetM, tetL and tetO). The pH, EC, TDS, SAL, TEMP, TSS, TBS, DO, and BOD for Tyhume River ranged as follows: 7.2-7.7, 125-141 μS/cm, 62-71mg/L, 0.06- 0.07 PSU, 11.3-20.2oC, 30.0-89.6 mg/L, 35.0-96.0 NTU, 8.2-9.8 mg/L, 2.0-4.2 mg/L, while for Great Fish River, the parameters were 8.0-8.2, 274-369 μS/cm, 137-184mg/L, 0.13-0.18PSU, 12.7-22.3oC, 44.3-99.4 mg/L, 48.0-214.0 NTU, 7.8-9.9 mg/L, 3.1- 4.9 mg/L, and at Keiskamma River they were 7.5-7.9, 153.2-285.0 μS/cm, 86-143 mg/L, 0.07-0.14 PSU, 11.0-21.4oC, 27.0- 55.6 mg/L, 31-61 NTU, 8.3-9.8 mg/L, 3.0-6.0 mg/L. A total of 1107 presumptive Acinetobacter spp. were recovered from the rivers sampled of which 428, 370 and 309 isolates were recovered from Tyhume, Great Fish and Keiskamma rivers respectively. However, only 844 was confirmed positive for the genus Acinetobacter and are recovered in the proportions 285 (77 percent), 219 (70.9 percent) and 340 (79 percent) from Great Fish, Keiskemma and Tyhume rivers respectively. Our finding revealed that 410 (48.58 percent) and 23 (2.7 percent) of the isolates were confirmed to be A. baumannii and A. nosocomalis respectively. Also, 308 (75.12 percent percent) A. baumannii and 3 (13.04 percent) A. nosocomialis isolates exhibited one or more virulence genes out of the seven tested, whereas 102 (24.88 percent) and 20 (86.95 percent) of the A. baumannii and A. nosocomialis isolates did not harbour any virulence gene. Additionally, OmpA was the most prevalent (p<0.05) virulence gene found in A. baumannii with 69 (45.10 percent), 52 (50.98 percent) and 77 (49.68 percent) isolates from Great Fish, Keiskamma and Tyhume rivers respectively. The rates of susceptibilities of A. baumannii and A. nosocomialis to the antibiotics followed the order; Piperacillin-tazobactam (72.8 percent ; 73.9 percent), Ceftazidime (70.5 percent ; 91.3 percent), Cefotaxime (16.8 percent ; 17.4 percent), Cefepime (88.5 percent ; 95.7 percent), Imipenem (95.9 percent ; 100 percent ), Meropenem (92.7 percent ; 91.3 percent), Amikacin (97.6 percent ; 91.3 percent), Gentamicin (89.8 percent ; 87 percent), Polymyxin B (84.4 percent ; 91.3 percent), Tetracycline (74.7 percent ; 78.3 percent), Ciprofloxacin (75.9 percent ; 78.3 percent) and Trimethoprim/sulfamethoxazole (74.0 percent ; 73.9 percent) respectively. Both A. baumannii and A. nosocomialis were highly susceptible to all the antimicrobials tested except cefotaxime where 64 percent and 78 percent intermediate responses were observed in the species. At least 10 isolates of A. baumannii were resistant against each of the antibiotics used. The modal multiple antibiotics resistance phenotypes (MARPs) for Acinetobacter spp. was MARP 3 (29.87 percent) and the least was MARP 10 and 11 (2.6 percent each). The antimicrobial resistance index (ARI) was higher at two sampling sites KE2 (0.33) and TY1 (0.22). Similarly, MARI showed that sampling sites KE2 was a hotspot for multidrug-resistant Acinetobacter spp. Of the five classes of ARGs studied, there was a widespread of β-lactamases (blaTEM) in the two Acinetobacter species, followed by sul2, which were detected in 67 (63.2 percent) and 44 (49.4 percent) isolates respectively, across the rivers studied. We conclude that aquatic resources of the study community are important reservoirs of pathogenic Acinetobacter species and antibiotic resistance determinants. The occurrence of clinically-important Acinetobacter species suggests possible contamination of these selected rivers which are consumed by humans and livestock, as well as being used for irrigation system, and this constitutes a risk to public health. It also shows that A. baumannii and A. nosocomialis can thrive in the aquatic environment. This study suggests that direct utilization of water from these sources for domestic and other purposes without any form of pre-treatment should be avoided. It is, therefore, necessary for regulatory authorities to monitor the release of domestic and industrial wastewater into these water bodies in order to prevent outbreaks of epidemics. , Thesis (PhD) (Microbiology) -- University of Fort Hare, 2019

Similarly, antibiotic resistance genes (ARGs) present in the Acinetobacter isolates were investigated including aminoglycoside resistance genes (aacC2, aphA1 and aphA2), β-lactamases resistance genes (blaTEM, blaSHV, blaOXA-1-like, blaCTX-M(GROUP 1), blaCTX-M(GROUP 2), blaCTX-M(GROUP 9), blaVEB, blaGES, blaPER, blaCTX-M-8/-25, blaOXA-48-like, blaVIM, blaIMP and blaKPC), fluoroquinolones resistance genes (qnrA, qnrB, qnrC, qnrD and qnrS), sulfonamide resistance genes (sul1 and sul2), and tetracycline resistance genes (tetA, tetB, tetC, tetM, tetL and tetO). The pH, EC, TDS, SAL, TEMP, TSS, TBS, DO, and BOD for Tyhume River ranged as follows: 7.2-7.7, 125-141 μS/cm, 62-71mg/L, 0.06- 0.07 PSU, 11.3-20.2oC, 30.0-89.6 mg/L, 35.0-96.0 NTU, 8.2-9.8 mg/L, 2.0-4.2 mg/L, while for Great Fish River, the parameters were 8.0-8.2, 274-369 μS/cm, 137-184mg/L, 0.13-0.18PSU, 12.7-22.3oC, 44.3-99.4 mg/L, 48.0-214.0 NTU, 7.8-9.9 mg/L, 3.1- 4.9 mg/L, and at Keiskamma River they were 7.5-7.9, 153.2-285.0 μS/cm, 86-143 mg/L, 0.07-0.14 PSU, 11.0-21.4oC, 27.0- 55.6 mg/L, 31-61 NTU, 8.3-9.8 mg/L, 3.0-6.0 mg/L. A total of 1107 presumptive Acinetobacter spp. were recovered from the rivers sampled of which 428, 370 and 309 isolates were recovered from Tyhume, Great Fish and Keiskamma rivers respectively. However, only 844 was confirmed positive for the genus Acinetobacter and are recovered in the proportions 285 (77 percent), 219 (70.9 percent) and 340 (79 percent) from Great Fish, Keiskemma and Tyhume rivers respectively. Our finding revealed that 410 (48.58 percent) and 23 (2.7 percent) of the isolates were confirmed to be A. baumannii and A. nosocomalis respectively. Also, 308 (75.12 percent percent) A. baumannii and 3 (13.04 percent) A. nosocomialis isolates exhibited one or more virulence genes out of the seven tested, whereas 102 (24.88 percent) and 20 (86.95 percent) of the A. baumannii and A. nosocomialis isolates did not harbour any virulence gene. Additionally, OmpA was the most prevalent (p<0.05) virulence gene found in A. baumannii with 69 (45.10 percent), 52 (50.98 percent) and 77 (49.68 percent) isolates from Great Fish, Keiskamma and Tyhume rivers respectively. The rates of susceptibilities of A. baumannii and A. nosocomialis to the antibiotics followed the order; Piperacillin-tazobactam (72.8 percent ; 73.9 percent), Ceftazidime (70.5 percent ; 91.3 percent), Cefotaxime (16.8 percent ; 17.4 percent), Cefepime (88.5 percent ; 95.7 percent), Imipenem (95.9 percent ; 100 percent ), Meropenem (92.7 percent ; 91.3 percent), Amikacin (97.6 percent ; 91.3 percent), Gentamicin (89.8 percent ; 87 percent), Polymyxin B (84.4 percent ; 91.3 percent), Tetracycline (74.7 percent ; 78.3 percent), Ciprofloxacin (75.9 percent ; 78.3 percent) and Trimethoprim/sulfamethoxazole (74.0 percent ; 73.9 percent) respectively. Both A. baumannii and A. nosocomialis were highly susceptible to all the antimicrobials tested except cefotaxime where 64 percent and 78 percent intermediate responses were observed in the species. At least 10 isolates of A. baumannii were resistant against each of the antibiotics used. The modal multiple antibiotics resistance phenotypes (MARPs) for Acinetobacter spp. was MARP 3 (29.87 percent) and the least was MARP 10 and 11 (2.6 percent each). The antimicrobial resistance index (ARI) was higher at two sampling sites KE2 (0.33) and TY1 (0.22). Similarly, MARI showed that sampling sites KE2 was a hotspot for multidrug-resistant Acinetobacter spp. Of the five classes of ARGs studied, there was a widespread of β-lactamases (blaTEM) in the two Acinetobacter species, followed by sul2, which were detected in 67 (63.2 percent) and 44 (49.4 percent) isolates respectively, across the rivers studied. We conclude that aquatic resources of the study community are important reservoirs of pathogenic Acinetobacter species and antibiotic resistance determinants. The occurrence of clinically-important Acinetobacter species suggests possible contamination of these selected rivers which are consumed by humans and livestock, as well as being used for irrigation system, and this constitutes a risk to public health. It also shows that A. baumannii and A. nosocomialis can thrive in the aquatic environment. This study suggests that direct utilization of water from these sources for domestic and other purposes without any form of pre-treatment should be avoided. It is, therefore, necessary for regulatory authorities to monitor the release of domestic and industrial wastewater into these water bodies in order to prevent outbreaks of epidemics. , Thesis (PhD) (Microbiology) -- University of Fort Hare, 2019

- Description: Training and development are regarded as significant tools for any organisation to achieve the target goals and objectives. These goals and objectives are heavily and highly dependent on its workforce. In the literature, it is well documented that many organisations invest in employees’ training and development to enhance their performance and the growth of the organisation. Many organisations, however, including the Buffalo City Municipality, regard training and staff development as needless expenditure, and always do little, or make no effort to improve employees’ technical know-how. Such actions incapacitate staff to adapt to the ever-changing working environment and rapid technological innovation. This study employed purposive sampling technique to draw a sample of 70 employees from a total of 150, through structured interviews and a self-administered questionnaire, to examine the effect of training and development on employees’ performance in the Buffalo City Municipality, situated in the Eastern Cape of South Africa. The findings of the study generally revealed that training and development does not only increase employees’ performance, but assists in developing the overall personality of employees by making them more productive through building their senses of teamwork, boosting the attitude of staff which is the most critical component in attaining profit, and developing a cordial relationship and connectivity between management and the workforce. The study, therefore, recommended that the municipality, as a matter of urgency, earmarks a certain percentage of its resources for employees training and development, based on identified skills gaps to sharpen employees’ skills, competencies, capabilities and technical know-how, to capacitate them to cope with the ever-changing working environment and innovations, and to enhance their motivation, satisfaction and performance. , Thesis (MPA) -- Faculty of Management and Commerce, 2019

- Description: Tuberculosis (TB) morbidity and mortality rates remain high globally and are even higher in Africa. The key factor that continues to drive the burden of disease is poor compliance / adherence to treatment regimens. This study aimed to identify determinants that continue to drive poor treatment adherence among low-income communities in South Africa. Methods A cross-sectional survey was conducted, drawing on TB patients who were defaulting on treatment. An assessment tool with several socio-economic and disease-related determinants was administered to participants. Data was entered into MS Excel and analysed in SPSS version 24. Results Regarding health services factors generally, all participants agreed that health service delivery was conducted in a conducive environment and that facilities were reasonably close to their places of residence. Participants demonstrated that health workers do not provide adequate information regarding medications that patients receive. Of patients cited, 11percent indicated that they stopped medications owing to health services. When questioned, participants reported that health workers shouted at them for coming late (e.g. after lunch) and that waiting times were very long. Approximately 85percent of the study participants were more likely to adhere poorly to TB medication owing to various factors such as comorbidities and personal perceptions of wellbeing / health status. Comorbidities are high among patients, with 58percent taking other medication while on TB treatment. Self-prognosis on wellbeing is significantly high, and 44percent reported a tendency to stop medication when they were seemingly in recovery. The unemployment rate among respondents was 78percent, with limited education: 69percent had below matric. Of the respondents, 40percent showed an unsatisfactory perception of their social and economic life, 55percent were somewhat satisfied and only 5percent were very satisfied. These indicators constitute a highly vulnerable community that depends heavily on subsidised healthcare from the state. Adherence to TB treatment is mainly influenced by poverty, the health service provider–patient relationship and perceived stigma. Limited family support was noted towards the treatment of patients. , Thesis (MPH) -- Faculty of Health Sciences, 2019

- Description: The primary goal of this study was to identify possibilities for a common ground for reconciliation and restoring law and order through internally driven post-conflict reconstruction and development (PCRD) in South Sudan to prevent the recurrence of violent conflict and to attain peace, socio-economic and sustainable development. The existing literature about PCRD is mainly written by authors, policymakers and scholars who mostly support externally driven interventions and operations of ready-made ‘solutions’ to complex problems in war-torn countries without exploring internally driven approval to solve these conflicts. It is because of the failure of these externally driven approaches and the absence of a common goal for reconciliation that this study has been conceived to explore alternative approaches for reconciliation and post-conflict settlement to restore responsible law and order, build resilient good governance and to build legitimate state institutions in South Sudan. To better understand in-conflict and post-conflict societies and their needs, the study uses a qualitative methodology approach through explorative and interpretative mechanisms to purposely put together face-to-face interviews of people’s opinions on the current civil conflict in South Sudan. The findings indicate that for peace to be restored there is a need for an internally national dialogue and reconciliation and external actors must support locally driven initiation to enable lasting peace to prevail in South Sudan. The research uses cosmopolitan conflict transformation resolution (CCTR) to demonstrate perspective and knowledge of the South Sudanese on peace-building to provide an alternative contribution to efficient intervention in the South Sudan conflict. Without peace there cannot be effective lasting development and without development, it is almost impossible to establish lasting peace. Hence, the study views PCRD more as a sustainable development intervention through an internally driven approach than a market-biased political process to prevent relapse of violent conflict in South Sudan. , Thesis (PhD) -- Faculty of Management and Commerce, 2019

- Description: Organic farming is growing gradually in South Africa. Its contribution to economic growth and poverty mitigation is notably in the pastoral areas in terms of providing adequate and affordable food for the incessantly growing population. Organic farming is also known for provision of employment and source of livelihoods for the rural populace as well as supply of raw materials to the country’s agro-allied industrial sector. For the purposes of this research, focus was only on profitability and technical efficiency because it is an essential subject in developing agriculture where resources are limited, but high population growth is very common. As a result, increased output will rely more on efficiency enhancements which will further intensify farmers’ income. As such, evaluating the extent for such efficiency enhancements within the system is a crucial prerequisite. The objective of the study was to assess the profitability and technical efficiency; and to identify socio-economic, institutional and farm characteristics that influence profitability and the technical efficiency of the small-scale organic crop farmers in the Buffalo City Metropolitan Municipality (BCMM). A purposive sampling technique was used to collect primary data from 160 small-scale organic crop farmers in BCMM. The gross margin estimation was used to estimate profitability, while multivariate Ordinary Least Square (OLS) was used to assess socio-demographic factors influencing profitability. The stochastic frontier model was used to determine the level of technical efficiency as well as the determinants of technical inefficiency of the farmers. The results of the gross margin estimation show that the small-scale organic maize (GM= R392 417.00) and cabbage (R196 489.00) farms were profitable. Similarly, the results of the OLS showed that one out of the eight variables namely, farming experience influences organic maize producers’ profitability, while factors such as gender, household size, and educational level emerged as the major significant factors influencing organic cabbage producers’ profitability. The stochastic results revealed that small-scale organic crop farmers in the study area are technically efficient at 86percent in maize production and 93percent in cabbage production respectively; and experienced unity return to scale (1.0) in maize and increasing return to scale (1.2) in cabbage. The results suggested that an increase in the use of input, would also intensify their productivity and efficiency. The results from the inefficiecncy model of the stochastic frontier further show that age and farming experience are the major determinants of organic maize producers’ technical inefficiency, while, factors such as age, years of schooling, farming experience, and household size were the significant determinants of organic cabbage producers’ technical inefficiency. To enhance the farming potential of these farmers, it is recommended that government and other several stakeholders such as researchers, entrepreneurs should invest more in organic crop farms since it is profitable and efficient in improving farmers’ livelihoods. There is also need for government to organise on-going workshops and extension training through the help of extension officers on how farmers can improve their production which will further enhance their income. , Thesis (PhD) -- Faculty of Science and Agriculture, 2019

- Description: The practice of strategy implementation is key to the public sector in Zimbabwe because it helps the government to be up to speed in providing services to the public. This research focused on the National Health Strategy 2009-2013 and its impact on health service delivery in Vungu Rural District Council Clinics. The research was based on qualitative desk study design which made use of existing data and semi structured interviews to understand the effect of the National Health Strategy on health service delivery in Vungu Rural Districts Council Clinics. From the literature reviewed and the data collected, it can be noted that lack of resources has had a huge effect on the execution of the strategy. The findings from the study show that the National Health Strategy was a good initiative. However, it lacked financial resources which posed challenges to the health workers in Vungu Rural District Council Clinics. The health workers were not very familiar with the National Health Strategy and this had a negative impact on its execution because they cannot execute a strategy that they are not familiar with. The study highlighted the importance of resources for the execution of the National Health Strategy. The study therefore sought to find ways the Zimbabwean Health System may formulate the health strategy with the limited resources in order to achieve desired goals. The Health Workers echoed the same sentiments that they needed resources for the implementation of the strategy. It is hoped that the findings would provide guidelines for the formulation and implementation of future health strategies. Recommendations given would ensure that there is utilisation of available resources, which would help in the execution of other health strategies to ensure efficient and effective health care service delivery. The recommendations are also intended to enhance the performance of health workers. Though the study was limited to Vungu Rural District Council Clinics the findings and recommendations would provide guidelines for other rural clinics as they use the National Health Strategy. , Thesis (PhD) -- Faculty of Management and Commerce, 2019

- Description: The aim of this study was to establish the influence of using GeoGebra as a manipulative tool in providing processes of Grade 11 circle geometry at one school in OR Tambo Inland. The study adopted a quantitative approach and utilised the quasi-experimental research design. The sample consisted of 107 Grade 11 mathematics learners. Sixty (60) learners were in the experimental group and 47 in the control group. Pre-test and post-test, and likert-scaled questionnaires were used as instruments. Reliability and validity were ensured through test-retest, as well as member checking and a pilot study. All ethical requirements were followed. Findings revealed that pre-test results did not show much difference in the performance of experimental and control groups. After using GeoGebra, it statistically emerged that control group respondents performed lower than the experimental group. Findings obtained from the questionnaire also showed similar patterns. The study also found that participants who learnt circle geometry using GeoGebra were significantly motivated and that GeoGebra allowed learners to be exceedingly creative and discover skills of solving geometry problems by themselves. The positive impact of using GeoGebra resulted in significant differences on academic performance. Based on gender, more females compared to males agreed that GeoGebra was an effective manipulative tool in learning circle geometry. Interestingly, boys performed better than girls in the post-test. The study concluded that students who used GeoGebra showed higher ability in conceptual knowledge compared to students who used conventional methods. It also concluded that GeoGebra had positive effects on learners’ understanding as learners became significantly active and responsible for their own learning process as the software allows a self-learning process. Recommendations included the need for teachers to use the latest technology and to vary their methods of teaching to motivate learners. There is also a need for a workable alternative opposed to the rigid axiomatic approaches to circle geometry to facilitate and enhance learners’ ability to make and test conjectures. Curriculum planners and subject specialists need to emphasise on education systems that shift teaching and learning away from the traditional methods and emphasise on learning rules for manipulating geometry problems. , Thesis (M.Ed) -- Faculty of Education Sciences, 2020

- Description: The aim of this study was to establish the influence of using GeoGebra as a manipulative tool in providing processes of Grade 11 circle geometry at one school in OR Tambo Inland. The study adopted a quantitative approach and utilised the quasi-experimental research design. The sample consisted of 107 Grade 11 mathematics learners. Sixty (60) learners were in the experimental group and 47 in the control group. Pre-test and post-test, and likert-scaled questionnaires were used as instruments. Reliability and validity were ensured through test-retest, as well as member checking and a pilot study. All ethical requirements were followed. Findings revealed that pre-test results did not show much difference in the performance of experimental and control groups. After using GeoGebra, it statistically emerged that control group respondents performed lower than the experimental group. Findings obtained from the questionnaire also showed similar patterns. The study also found that participants who learnt circle geometry using GeoGebra were significantly motivated and that GeoGebra allowed learners to be exceedingly creative and discover skills of solving geometry problems by themselves. The positive impact of using GeoGebra resulted in significant differences on academic performance. Based on gender, more females compared to males agreed that GeoGebra was an effective manipulative tool in learning circle geometry. Interestingly, boys performed better than girls in the post-test.

- Description: This study is conducted to address the perceptions, opinions, and feelings of rural community members with regard to agriculture as poverty alleviation strategy at Tamarha Administrative area, Eastern Cape, South Africa. The study intended to uncover the community members feelings, reactions, opinions they might be having as the area is no longer relying on agriculture as their source of income as well as their poverty alleviation strategy as well as the impact it is having on their everyday life. Lastly, the study sought to examine support services rendered by the professionals working directly with communities to ensure development in rural areas. The researcher adopted both qualitative and quantitative research methods. Purposive and snowball sampling was employed to recruit 20 community members from Tamarha Administrative area. The age of the community members was between 25 and 65. In addition, purposive sampling was adopted to recruit six professionals who are directly working in developing community members. Data was collected using face-to-face, semistructured individual interviews, one interview per research participant, and using one focus group discussion with professionals working with. Regarding quantitative method, the researcher has utilized questionnaires to collect data The researcher analysed data through thematic content analysis for qualitative method as well as SSPS for quantitative method. The study findings indicate that youth are not interested in agriculture and only elders who have been involved in agriculture that are seeing the value and importance of using agriculture again. Majority of the community members especially (elders) are seeing agriculture as poverty alleviation strategy, and that they have benefited a lot from agriculture as most people were working and had income. There were few youths who were not working nor schooling and there was low rate of crime and low rate of drug abuse. The youth seemingly are having different perception and opinions about agriculture as they are not familiar with the system. The recommendations from the findings that there should be continuous empowerment in skills development from professionals working with agriculture. The government departments who are directly funding the agricultural projects, should monitor and evaluate the projects to ensure sustainability to the agricultural projects. The youth should be encouraged to use the resources that are available within the community. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2019

- Description: Traditional healing, alternately called traditional medicine or complementary and alternative medicine (CAM), has been in existence for a long time and sometimes used alongside popular western healing methods (Kirmayer, 2004). The focus of the current study was on the role and function of traditional healing infamilies living in the Eastern Cape Province. Through an Afrocentric lens, the study sought to explore the manner in which traditional healers helped family members deal with difficult life situations. The researcher used an explorative, descriptive, qualitative design, through focus group discussions, in-depth interviews and observations. Selection of participants was done through purposive sampling. The participants were heterogeneous in terms of age, gender, level of education, occupation and religion. Data analysis was employed through Interpretive Phenomenological Approach using Afrocentric theory as a metatheory and Ubuntu and sociocultural theory as complementary theories to understand the participants’ perceptions and experiences of the role played by traditional healing in building family resilience. Ethical principles were adhered to, for example voluntary participation and informed consent. Research findings revealed a variety of traditional ritual performances which embraced principles of Afrocentricity and Ubuntu – interconnectedness, interdependence and collectivism, spirituality, good communication and social support – as key elements in traditional family relationships. The traditional healers played a significant role in mentoring family members and mending broken families and alleviating suffering. They do this in line with the convictions of the ethical principles concerning respect cultural beliefs and values of consumers of psychological servises. Since the study was conducted in a rural area with isiXhosa speaking family members, there is a need for inclusion of other racial groups and family members living in urban areas. , Thesis (PhD) (Psychology) -- University of Fort Hare, 2021

- Description: An intellectually safe classroom (ISC) is essential for teaching and learning to occur. The aim of this study was to investigate Grade 6 teachers’ views and practices regarding the creation of intellectually safe classroom environments. The paradigm that was used in the study was the interpretive paradigm and the research approach was qualitative. A case study design was used. Three Mdantsane primary schools was purposively selected and two Grade 6 teachers from each school were the participants. Semi structured interviews and observations were used to collect data. The research found that participants are cognizant of the need to develop ISC. They define ISC as a classroom that is both emotionally and physically safe for learning to occur. The participants are very conversant with the benefits of ISC. Most of the teachers purposefully tried to implement ISC. This included the establishment of classroom rules, and they acknowledged the role that the teacher plays in setting up an ISC and the manner in which they establish trust and co-operation within their classrooms. However, they are often constrained in their implementation of ISC by their own teaching styles and by factors outside of their control. This emphasised the pivotal role that teachers have in the establishment of an ISC. It is recommended that ISC be implemented in all classrooms with the entire school community working together to do so. , Thesis (MEd) -- Faculty of Education, 2019
