- Description: This study examines the lifestyle decisions of people who are diagnosed with HIV/AIDS in King Williams Town, Eastern Cape. The study was motivated by the ever growing number of people who are now living with HIV/AIDS. Therefore the researcher intended to examine their decisions regarding sexual choices, reproductive health, diet, physical fitness and their coping strategies. The study found that there is very low uptake of Voluntary Counseling and Testing (VCT). Most people only get tested if they are compelled by other factors, like illness and pregnancy. It also found that HIV positive people continue to engage in risky sexual behaviour regardless of their positive status. In addition it also found that HIV positive status does not affect sexual activity and social support from family and friends is a very important factor that is helping the respondents to cope with HIV diagnosis.

- Description: The purpose of this study was an investigation of the reasons for persistent poverty and low level of economic growth and development in the OR Tambo district municipality of the Eastern Cape Province since the advent of democracy in South Africa. To accomplish this objective, a case study of the OR Tambo district municipality was undertaken within the concept of development, seeking to answer three research questions: What are the factors that explain the persistence of poverty in the OR Tambo district municipality? Why is the OR Tambo district municipality the most exposed to poverty in relative and absolute terms? What have state poverty intervention strategies done to alleviate poverty in the OR Tambo district since the advent of democracy in South Africa? Mainly qualitative data collection methods, involving in-depth semi-structured interviews, textual and document analyses, focus group discussions and observations were employed to answer the research questions. A purposive sampling of nineteen participants, supplemented by three focus groups, was selected. The macro-level case study design was supplemented by micro-level documentary evidence on poverty and development. From the synthesised findings of the investigation, twelve causal factors were identified as responsible for persistent poverty and low level of economic growth and development in the OR Tambo district. These included political neglect, agricultural neglect, poor infrastructure, corruption, poor service delivery, poor quality of natural resources, brain drain, migrant labour system, culture of tolerance and conservatism, culture of dependence, no long-term development strategy and globalisation.

- Description: This study investigated the experiences of the Development Support Group (DGS) when implementing the IQMS (Integrated Quality Management System) in Butterworth District of the Eastern Cape. The aim of the study was to explore the experiences of the DSG when implementing the IQMS in an attempt to determine whether the DSG can cope with the task of being part of evaluation in education, and how the negative experiences could be improved. In order to get the experiences of the DSG when implementing the IQMS, the researcher embarked on this phenomenological study. Data were collected by means of one-on-one semi-structured interviews and the perusal of the IQMS document, Resolution 8 of 2003. Responses from the participants were tape-recorded and eventually transcribed, analyzed and interpreted. The main feature revealed by the study is gross lack of confidence, feeling of insecurity and ambivalence on the part of the DSG. On the basis of the findings, recommendations that will assist the DSG (and other IQMS implementers) to improve IQMS implementation, have been made. This study also serves as the voice of the DSG for they have also made suggestions to improve on the negative experiences they have highlighted. The conclusions arrived at in this study are specific to the DSG of the sampled schools. The conclusions reflect and explain the challenges faced by the DSG in Butterworth district. But the findings give a reflective explanatory depth to the experiences the DSG when implementing the IQMS.

- Description: SFME and HD for the extraction of essential oil in Lavandula officinalis in Alice have been reported. A total of 59 compounds were identified with the major compound being 1,8-cineole, an oxygenated monoterpene, with 46.89% and 44.84% yield obtained for HD and SFME respectively. Charge transfer (CT) complexes formed between α-pinene, 1,8-cineole and camphor as electron donors with iodine as the electron acceptor have been studied spectrophotometrically in methylene chloride solution. The Benesi- Hildebrand equation has been applied to estimate the formation constant (Kf) and molecular extinction coefficient (εCT). The value of Kf is the highest in camphor-I2 complex compared to the other two complexes. Antibacterial assessment was carried out on the various reagents, determining the MIC of individual reagents and in combination. The results show an improvement, on combination of the various reagents than when tested alone.

- Description: The aim of this study was to investigate the schooling experiences of four orphaned learners at Mandini Secondary School in the Maluti District of Education in the Eastern Cape. The study adopted a qualitative research methodology and a phenomenological research design. Purposive sampling was adopted and the tape recorded narrative responses of all four respondents, were obtained from the use of in-depth phenomenological unstructured interviews. The respondents were four orphaned children (two males and two females) between the ages of fifteen and twenty years. The study used the Social Rupture Theory as lenses of analysis of the findings. This was considered a very sensitive topic because the respondents had to relate issues which could result in them reliving traumatic experiences. As a result more attention was paid on ethical issues and making the respondents feel comfortable. The respondents were capable of distinguishing between their quality of life while their parents were still alive and well; when they (the parent[s]) became sick and when they eventually died. Furthermore, the respondents highlighted the negative effects of parental absence in their education. In addition, these orphaned children formed relationships with the school community after their parents’ death which, to some extent, had a positive effect on their schooling. Based on these findings the study suggests that educators need to be trained in diagnosing psycho-social problems and given skills to deal with them. Similarly, short courses should be organized for guardians and community development workers in identifying and counseling of problems.

- Description: Discovery of cheap, nontoxic and readily available antiatherosclerotic drugs is an extraordinary challenge in this modern world. Atherosclerosis and cardiovascular diseases have been predicted to be the leading cause of death by the year 2030. Hence, this thesis was designed to search for plant (s) with anti-atherogenic properties, investigate its possible side effects and extrapolate its likely mechanism(s) of action. An ethnobotanical survey was employed in identification of locally important plants used for the management and treatment of cardiovascular diseases and its predisposing factors in Nkonkobe Municipality, Eastern Cape in South Africa. Information on the names of plants, their parts used and methods of preparation was collected through a questionnaire which was administered to herbalists, traditional healers and rural dwellers. The most frequently used plant (Rhizomes of Tulbaghia violacea Harv.) was investigated for toxicity using brine shrimp lethality (in vitro) and in vivo toxicity test (acute and subchronic) on rats to determine safety dosage. The in vitro antioxidant and free radical scavenging activity of the plant was investigated using models such as 1,1-diphenyl-2- picrylhydrazyl (DPPH), superoxide anions, hydrogen peroxide (H2O2), nitric oxide (NO), 2,2’- azinobis [3-ethylbenzothiazoline-6-sulfonic acid] diammonium salt (ABTS), lipid peroxidation inhibition and the ferric reducing agent. Phytochemical content and the effect of oral administration of fresh methanolic extract rhizomes of Tulbaghia violacea (250, 500 mg/kg. bwt/day) on Lipid peroxidation (TBARS), serum and tissue antioxidant enzymes in normal, hypercholesterolemic and diet induced atherogenic rats were also assessed. More so, the potential of the extract (250 and 500 mg/kg. bwt) to protect against atherogenic diet (4 percentage cholesterol 1 pecentage cholic acid and 0.5 percentage thiouracil) induced fatty streaks formation, dyslipidemia, oxidative stress and endothelial dysfunction was also investigated. Ethnobotanical study revealed that 19 plant species are used for the treatment of heart related diseases in the Municipality. 53 percentage of the plants mentioned were used for the management of chest pain, 47 percentage for high blood pressure, 42 percent for heart disease, 16 percentage for stroke and 11 percentage for the treatment of hypercholesterolemia. Tulbaghia violacea was repeatedly mentioned as the plant species used for the treatment of high blood pressure and predisposing factors in the study area. The brine shrimp cytotoxicity test revealed that fresh, dried methanolic extracts and essential oil of the T. violacea exhibited a high degree of cytotoxic activity with IC50 values of 18.18 (fresh) and 19.24 (dried) μg/ml. An IC50 value of 12. 59 μg/ml was obtained for the essential oil of the plant. The low cytotoxicity values obtained, suggested that rhizome of T. violacea may serve as a potential source of antimicrobial and anticancer agents. In vivo acute study of single oral administration of 5g/kg dose does not produce mortality or significant behavioral changes during 14 days observation. In the sub-chronic study, the extract (250, 500 mg/kg/bwt/ day) administered for a period of 28 days showed no mortality or morbidity. The weekly body and organ weight of the rats showed no significant differences between the control and the rats treated with the extract. The extract at all doses does not show any effect on of biomarkers of liver or renal damage. However, a significant decrease in the activity of ƔGT was observed in the extract treated groups. Hematological evaluation revealed that oral administration of fresh methanolic extracts of rhizomes of T. violacea does not cause anaemia or leucocytosis in the animals. Furthermore, histopathology results of the internal organs revealed no detectable inflammation. These results demonstrated that the rhizome extract of T. violacea was potentially safe for consumption orally even in chronic concentration. In vitro antioxidant evaluation showed that the essential oil, fresh and dried methanolic extracts exhibited potent antioxidant activities in a concentration dependent manner. Phytochemical investigation reveals that the fresh and the dry extract of RTV are rich in flavonoid, flavonol, phenols, tannin and proanthocyanidin, while the essential oil contained dimethy disulfide, dimethyl trisulfide, (methyl methylthio) methyl, 2,4-dithiapentane (11.35 percent) and (methylthio) acetic acid, 2- (methylthio) ethanol, 3-(methylthio) - and propanenitrile (7.20 percent). The fresh extract had higher radicals scavenging activity than the essential oil or dried extract, with 50 percentage inhibition of DPPH, hydrogen peroxide and lipid peroxidation at a concentration of 35.0 ± 0.12, 19.3 ± 0.11 and 17.9 ± 0.15 μg/ml respectively. Oral administration of methanolic extract of RTV in 125, 250 and 500 mg/kg to female Wistar rats significantly inhibited reduction of glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT). The extracts also inhibited (p< 0.05) lipid peroxidation in normal, high cholesterol and diet induced atherosclerosis fed rats in a dose dependant manner. Also the extract (250 and 500 mg/kg/bwt/day) caused a significant (p<0.05) improvement in body weight of treated animals compared with untreated hypercholesterolemia control rats. The extracts also protected significantly (p<0.05) against atherogenic diet induced liver damage or fatty streaks formation in the aorta as revealed by histological examination. The anti-cholesterolemia and anti-atherosclerotic activities of the extract compared favorably well with standard drugs Gemfibrozil and Atorvastatin respectively. Conclusively, rhizomes of T. violacea possess significant anti-atherogenic activity and its mechanism of action(s) may be due to its antioxidant and anti-hypercholesterolemia properties. The results of this study also suggested that rhizome of T. violacea is relatively safe for human consumption and it may be used as an alternative to garlic.

- Description: Effects of feeding Moringa oleifera leaf meal as an additive on growth performance of chicken, physico- chemical shelf-life indicators, fatty acids profiles and lipid oxidation of broiler meat The main objective of the study was to determine the effect of M.oleifera leaf meal (MOLM) as an additive on growth performance, carcass characteristics, physico-chemical shelf-life indicators (colour, ultimate pH, driploss), fatty acids profiles and lipid oxidation of meat from broilers. A total of 432 1day old unsexed broiler chicks (Aviane 48) were randomly allocated to four dietary treatments (TRTS) in 72 cages. There were 18 cages per treatment and each cage allocated 6 chicks. Water and feed was provided at ad libitum. The feeding phases were, prestarter (0-7 Days), starter (8-18 Days), grower (19-28 Days), finisher (29-35 Days). The four TRTS contained graded levels of MOLM at 1000g/ton, 750g/ton, 500g/ton, and 0g/ton (control), respectively. The birds were slaughtered at 35 days of age. Breast muscles were sampled for meat, ultimate pH (pHu ), colour, drip loss over a 7 days shelf-life test. After each day’s test sub-samples were dipped in liquid nitrogen and kept at -180 C for thiobarbituric acid reactive substances determination. On Day1 and Day 7 extra sub-samples were also kept at -180 C for fatty acids analysis.The TRTS had no effect on average feed intake (AFI), feed conversion efficiency (FCE), and on average daily gain (ADG). Slaughter weight (SW), carcass weight (CW), dressing percentage and gizzard weight (GW) values were similar in all TRTS. Liver weight (LW), heart weight (HW), and gastro-intestinal fat (GIF) differed in all the TRTS, with treatment 2 having the highest value of HW (28.3±2.55), and LW (44.2±1.60) was the highest on treatment 4 . The pH values in all TRTS were constant from Day1 to Day5, reached peak on Day6, and then declined on Day7. Meat from broilers given treatment 1 with MOLM (1000g/ton) had the highest lightness (L*) values. The redness (a*) values were the highest in meat from treatment 2 (750g/ton MOLM). Treatments had no effect on yellowness (b*) values and on drip loss of the breasts. During storage L* values were high from Day1 to Day5 and decreased from Day6 to Day7. Drip loss increased with storage time as expected. Treatment 4 (control) had the highest proportions of poly-unsaturated fatty acids (PUFA) (30.3±1.87). Treatment 1 (1000g/ton) had the highest proportion of saturated fatty acids (SFA) (60.9±1.87). Treatment 1 (1000g/ton) had the highest proportion of SFA (60.9±4.30). Treatment 2 (750g/ton) had the highest n-6/n-3 ratio than other TRTS. Days had no effect (P>0.05) on PUFA, SFA, and n-6/n-3 ratio. Treatment 1 had a highest amount of malondialdehyde (MDA), treatment 4 had no effect (P>0.05) on MDA . Storage time had an effect (P<0.05) on MDA levels, except for on Day1 and Day7. Day2 had the highest amount of MDA (0.7±0.08). The use of MOLM as an additive in broiler diets reduced lipid oxidation in meat, and maintained the quality of the broiler meat during storage. It also did not have any adverse effects on the growth performance of broilers. Therefore, it has the potential to be used as an additive in broiler diets.

- Description: The purpose of the study was to assess the implementation of intervention programmes that ensure the right to education for orphans in schools in the King William’s Town District. Data from the study revealed that there were a number of challenges faced by orphans with regards to accessing social grants and this affected their school performance negatively. Some of the challenges were (1) even though orphans were receiving the social grant, it was inadequate to provide for their home and school needs; (2) there was lack of information by applicants to access documents they needed to apply for social grants. This was an impediment to access to funds from social grants. (3) The long distances travelled by people to reach social services posed obstacles to those wishing to apply for grants. (4) Applicants lacked proper documentation such as birth certificates and parents’ death certificates which could impede application processes for social grants and (5) Lack of monitoring of social grants resulted in the misuse of funds by some caregivers. In the schools it was also established that there was irregular distribution of food parcels which resulted from some people who gave food to their families and friends, leaving the needy ones out. The No fee policy however was a success as most learners were able to remain in school. With regard to school attendance, some of the challenges were: (1) that some learners were struggling to buy school books as this was not covered by the policy. (2) There was slow implementation of scholar nutrition programme with some schools in quintile 1-3 still not being able to benefit from the programme. (3) Scholar transport was not available to most of the learners and (4) learners were without counseling services, since teachers were not trained in psychosocial support. Nonetheless, social workers were adequately trained to provide psychosocial support to learners. In addition, non governmental organizations contributed a vital service by providing orphans with uniforms and food. However their work was limited by resources and funding. The study was situated in the interpretive paradigm which seeks to construct detailed descriptions of reality. The qualitative methods were suitable for data collection purposes because they allowed the use of interviews which collected detailed, authentic information of what goes on in the schools. It was therefore the best method for the research study which seeks to assess implementation of intervention programmes for orphans as they related the challenges they encounter in the implementation of intervention programmes in their schools. Purposive sampling was used to select 8 orphans, 8 caregivers, 4 principals, 4 teachers and 4 social workers from the 4 schools in the district. The study recommends that the Child Support Grant be reviewed upwards and that monitoring be strengthened so that grants are not misused. It is further recommended that the department of social services synchronize its information dissemination strategies with other stakeholder departments, such as the department of education so as to benefit orphans. It is also recommended that the No fee policy be strengthened by such additions as providing books for orphans and other vulnerable children in schools. Finally the study recommends scholar transport to be implemented as learners still have to walk long distances to school. , Thesis (MEd) -- Faculty of Education, 2012

- Description: A research was conducted on cotton to test different plant extracts with potential insecticidal properties against bollworms (Noctuidae) and leafhoppers (Cicadellidae) for the use by small-scale, cotton farmers. The study was carried out during the 2006/07 and 2007/08 seasons at ARC Institute for Industrial Crops, Rustenburg (25°39.0 S, 27°14.4 E) in the North West Province of South Africa. Four organic insecticides, tobacco (Nicotiana tabacium), khaki weed (Tagetes minuta), thorn apple (Datura stramonium) and garlic (Allium sativum) were compared with two chemical treatments, Mospilan® (acetamiprid) and Decis® (deltamethrin), and an untreated control. The cultivar, DeltaOPAL, was planted and the trial conducted using standard practices. Overall, Decis® and tobacco treatments exhibited significantly less bollworm larvae than the other treatments. Tobacco was the most promising biological pesticide against American bollworm (Helicoverpa armigera) and spiny bollworm (Earias insulana) larvae. All the treatments were significantly effective against the red bollworm (Diparopsis castanea) larvae, but Decis® and Mospilan® provided the best control. Although khaki weed, garlic and thorn apple were promising biological pesticides against the bollworm complex, tobacco was the most effective organic treatment. Mospilan® seemed to be more effective on the control of leafhoppers (Jacobiella fascialis), followed by Decis® and tobacco. Among the plant extracts, tobacco and garlic gave higher seed cotton yields compared to the khaki weed and thorn apple during both study seasons. In 2006/07, none of the treatments reached the corresponding economic threshold levels (ETLs). In contrast, in 2007/08, only rarely were the treatments (mostly Decis® and Mospilan®) below the corresponding ETLs. These differences were attributed to the higher rainfall recorded during the 2007/08 season, which reduced the effectiveness of the treatments by partly washing away the pesticidal applications. In addition, a high weed infestation also created competition for nutrients in the soil, thus resulting in lower (0.50-1.25 ton/ha in 2007/08 vs 2.50-5.00 ton/ha in 2006/07), but acceptable cotton seed yields. In conclusion, it is suggested that some plant extracts (particularly from tobacco and garlic) can be used as a cheaper and more environment-friendly alternative to chemical insecticides for the control of bollworms and leafhoppers, although it has been demonstrated that their efficacy do not reach the one of chemical treatments. Further research in the near future is recommended.

- Description: This thesis covers a period of drastic change in that part of Xhosaland later known as Victoria East. Chapters one and two deal with the clash between the Glasgow missionaries at Lovedale and the amaXhosa who were expected to simply discard their way of life in favour of the new dispensation. Chapter three explains the arrival in the Eastern Cape of the amaMfengu, formerly called abaMbo, and their role in the divisive policies of the colonial government. Chapter four recounts the brief interlude (1836-1846) during which the colonial government tried but ultimately rejected a more equitable model of cross-border relations known as the Treaty System. The final chapter deals with the introduction of direct rule over the newly-created district of Victoria East, and with the policies of Henry Calderwood, its first magistrate, which were artfully constructed to perpetuate ‘Divide and Rule’ so as to maintain a comfortable life for the white settlers in the border area.

- Description: The researcher’s interest in this study is in teachers’ perceptions and principals of the Integrated Quality Management System (IQMS). This study examines teachers’ understandings of this quality management and performance appraisal system, how teachers perceive the instrument used to manage and monitor their performance and the performance of their schools, and what lessons may be learnt regarding the implementation process of the IQMS. The investigation was carried out in three Butterworth District schools in the Eastern Cape. The researcher made use of qualitative methodology to obtain data from a sample of 3 principals, 9 teachers and 1 district official. Data were collected from these respondents by means of in-depth, semi-structured interviews and through document analysis. The study found that some of the teachers and principals felt that they did not understand the IQMS, and they complained that the system is fraught with many obstacles that need to be addressed in order to promote the effectiveness of teaching and learning. The participants also spoke of multiple factors that contribute negatively to this phenomenon, which include the fact that the teachers’ workload is increased by the IQMS, time constraints, inadequate training, vague and unfamiliar language, the financial incentive that is attached to the instrument, and the many structures in the implementation process. In addition, the system seems to encourage a bureaucratic style of management. Teachers and principals also suggested ways in which the IQMS could be structured by the Department of Education for greater efficiency in education.

- Description: The aim of this study was to explore how peer education is enhancing social-emotional learning in four secondary schools in Fort Beaufort Education District. An empirical investigation using the qualitative approach examined the situation of the peer education clubs at the four schools. Data was gathered using interviews, focus groups, observations and document analysis. The purpose of the study was to examine the role of peer education programmes in enhancing social and emotional learning in schools. In this research study specifically the qualitative research approach was used. The study also adopted a purposive sampling procedure which is acceptable for special sampling situations where the researcher applied her own experience to select cases which form part of the participants. Four schools were selected, four principals, four teachers who work with peer education clubs, four focus groups, one HIV/AIDS district coordinator, and one peer group trainer. It emerged from the analysis of the collected data that peer education clubs in Fort Beaufort have a number of challenges facing them, resulting in them making insignificant contributions towards the enhancing of social-emotional learning. The clubs’ efforts have resulted in little positive behavioural change among the youth. Among the challenges revealed are: lack of proper structures and support from school administrators, poor selection of peer educators, lack of time and facilities in which to carry out their work, lack of adequate training for both teachers and peer educators. Teacher interference was also cited regularly at all four schools, thereby defeating the whole idea of peer education. The study also revealed that peer educators in Fort Beaufort are not receiving adequate support from other stakeholders like, the police, the justice department and social welfare. Another critical observation made during the study was that peer education clubs are lacking clear standards of practice, rigour and sustainability, all which should be addressed in order to enhance social-emotional learning in schools. Data was analysed using a thematic content analysis. The analysis was carried out in a manner that related to the research questions and objectives in the study. A transcript was made from the respondents’ answers. Reflection and coding was done and data was categorised as an important learning tool in schools, and to recognise its contribution to social emotional learning. The study concluded that peer education clubs in schools, despite their huge potential to improve both behaviour and academic results, are not being given a conducive environment to operate in or the necessary support. This effectively means that learners with some behavioural problems and who have the potential to reform are also being denied the opportunity to lead better lives. The Department is advised to increase the number of both peer education trainers and trained peer educators. Furthermore the training period of peer educators should be increased from the current five days. There is need for the Department of Education to formalise peer education clubs in schools and craft laws that makes it mandatory for schools to provide the clubs with decent facilities like confidential rooms to conduct their activities. More so the study recommends that there is need to train all teachers in schools in social skills and not only LO teachers to ease supervisory burden on the LO teachers.

- Description: The Kalagadi Manganese mine in the Kuruman area of the Northern Cape Province of South Africa contains reserves of Mn ore in excess of 100Mt. Mineralization in the mine lease area is restricted within the Hotazel Formation of the Voȅlwater Subgroup, belonging to the Postmasburg Group, the upper subdivision of the Transvaal Supergroup. Surface topography is characterized by flat lying, undulation with minimal faulting and the ore are slightly metarmophosed. This study investigates the general geology of the mine, lithostratigraphic subdivision and correlation of the economic Lower Manganese Orebody (LMO) of the Kalagadi Manganese Mine in order to guide mining plan and operations once the mine is fully commissioned. At the commencement of this study, Kalagadi Manganese mine was a project under exploration with no specific geology of the mine lease area and no lithostratigraphic subdivision. The study also aimed determining the extent of lithostratigraphic correlation between the LMO economic orebodies of the Kalagadi Manganese mine with that of underground Gloria and open-pit Mamatwan mines. Four methods including petrographic microscope, Scanning electron Microscope (SEM), X-ray diffraction (XRD) and X-ray fluorescence (XRF) analyses were applied mainly for the mineral identification, chemical composition and ore characterization of the Lower Manganese Orebody (LMO) at Kalagadi Manganese mine. The results of this study indicates the following: (1) Eleven textural distinct zones with economic zones restricted to the middle while the lower grade zones are confined to the top and bottom of the LMO; (2) The economic zones, comprising of Y, M, C and N subzones attain an average thickness of 10 m and are graded at an average of 40% Mn while the Mn/Fe ratio varies from 6 to 9; (3) The most economic zones are M and N subzones which are mostly characterized by oxidized ovoids and laminae, a characteristic applicable even to other zones of economic interest; (4) Braunite is the main mineral of the manganese ore and is often integrown with kutnahorite and other minerals (hematite, hausmannite, Mg-calcite, calcite, jacobsite, serpentine and garnet) which are present in variable amounts; (5) The Mg-rich calcite (Ca, Mg)CO3 is the second dominant manganese carbonate mineral and it corresponds to elevated MgO concentration and is often associated with marine environment. The occurrence of the Mgcalcite is not common in the manganese ore of this area except for the Mn-calcite, which was not determined by XRD analyses in this study; (6) MnO is the most abundant major oxide in the manganese ore while other major oxides present in decreasing order of abundance are CaO, SiO2, Fe2O3, and MgO. The oxides TiO2, Na2O, K2O, Al2O3, and Cr2O3 are depleted and are mostly 0.01wt% and 0.001wt% respectively while P2O5 concentrations are low ranging from 0.02wt% to 0.3wt%. The trace element concentrations of Ba, Zn and Sr in most borehole samples are slightly elevated ranging from 100ppm to 3.9% (36000pm) while Co, Cu, Ni, Y, As, Zr, V and La rarely exceed 50ppm. The enrichments of Cu, Zn, Ni, Co and V that are commonly associated with volcanogenic hydrothermal input in chemicals may reach up to 70ppm; (7) The mineralogical and geochemical characteristics of the manganese ore in the Kalagadi Manganese mine lease area are similar to that of Low-Grade Mamatwan-Type ore. The cyclicity (Banded Iron Formation ↔ Hematite lutite ↔ braunite lutite) and alternation of manganese and iron formation have been confirmed; and (8) The oxygen δ18O isotope values (18‰ to 22‰) indicate a slight influence of metamorphism of the manganese ore. No positive correlation exists between δ13C vs δ18O values and Mn vs δ13C values. Such observations indicate minimal action of organic carbon during manganese precipitation where the organic matter was oxidized and manganese content reduced. On the other hand, the manganese carbonates (CaO) are positively correlated with carbon isotope, this indicates diagenetic alteration and the involvement of biogenic carbonate during the formation of manganese carbonates. It is concluded that the lithostratigraphic subdivision at Kalagadi Manganese mine is best correlated physically, mineralogically and geochemically with that of Gloria mine operating in the Low Grade Mamatwan - Type ore while correlation with an open-pit Mamatwan mine is also valid.

- Description: The thesis examines the photographic collection of Joseph Denfield, an archivist and historian who experimented with photography over a twenty-year period. The study is located within the field of critical visual studies that focuses on historical photography in its depiction of identities and groups in the context of social change. The thesis pays attention to the manner and extent to which Denfield participated in regional visual economies at various moments during his photographic career in order to establish his contribution towards a visual history in Africa and more broadly Southern Africa. It follows Denfield’s career trajectory chronologically. It begins with a study of his photographic work in Nigeria which was oriented around so-called ‘pagan tribes’ and which was framed within the discourse of ethnography. It then pays attention to his growth as an artist in photography that resulted from years of exhibiting in salons. I read these photographs and texts in relation to his earlier work in Nigeria given the extent to which he drew on anthropological discourses. It is through his involvement with photographic art circles that Denfield developed as a historian as a result of his research into the history of photography and regional visual histories. This took the form of both unearthing historical photographs as well as photographing historical sites to construct the past in particular ways through the visual. At each stage he translated these histories into public forms of representation and power thus he figures among a small group of ‘colonial’ photographers that shaped the visual economy of Southern Africa. Through a detailed study of his work, the thesis thus aims to re-think through new dimensions of visual culture.

- Description: This study focused on establishing the impact of job satisfaction (JS) and organisational commitment (OC) on turnover intentions of high school teachers in Fort Beaufort. Quantitative research methodology was used to gather data with the use of the short version of the Minnesota Job Satisfaction Questionnaire; the Organisational Commitment Questionnaire measuring three facets of commitment (affective, continuance, and normative); and Turnover Intention Questionnaire consisting of three items. Validity and reliability of each instrument was presented and explained. Data analysis was facilitated by the use of Statistical Package for Social Sciences (SPSS). The results indicated that teachers’ level of satisfaction was high with many aspects of their job and it was low with some aspects with pay and the amount of work being the lowest. A negative relationship between job satisfaction and turnover was established, and organisational commitment was found to influence turnover intention.

- Description: The demise of apartheid and the ushering in of the New Dispensation in 1994 necessitated the dismantling of the old structures of government which divided the people along racial lines and building a united South Africa based on the principles of the new Constitution.Chapter 10 of the Constitution No. 108 of the Republic of South Africa gives guidelines and principles on how Public Administration should be governed. Section 195 provides for the basic values and principles which govern public administration. The Eastern Cape Department of Education is faced with a problem where the basic values and principles which govern public administration in schools had either not been observed or are completely compromised despite the involvement of labour unions. This is evident in the final results of matrics year after year which became a social concern and the national question. The state of affairs is not improving despite the involvement of labour unions and this prompted the National government to intervene through Section 100. This study will try to explore and mitigate this undesirable state of affairs. The involvement of labour unions is a critical question as to whether their involvement enhances proper governance and policy intentions in schools which will enhance service delivery and increase performance and output results. The researcher followed a multi-method approach to benefit from the diversity of opinions and understand the problem better.

- Description: The problem of school under-performance as defined by the level of pass rates of learners in the matric examinations has been a point of educational debate in South Africa for a number of years, especially after the attainment of democracy. In the Eastern Cape, Matric Intervention Strategies (MIS) have been used to address the problem. The aim of this study was to investigate educator perceptions of the impact of the MIS on selected under-performing high schools in the Queenstown District.Two case study schools classified as consistent under-performers participated in the study. Data was collected through in-depth interviews of key educators in these schools. There were five main findings. First, educators felt that Departmental intervention strategies had not made any significant improvement in addressing underperformance in the two case study schools. Second, participants saw underperformance by schools as caused by a myriad of factors which include those related to leadership and management at school and district levels and educator and learner factors, as well as teacher union interference. They did not see MIS as being able to address the causes simultaneously. Third, the implementation of the (MIS) at school level was poorly monitored by the Departmental officials. It was reported that under-performing schools were hardly visited and supported by the subject advisors and (MIO)s. Fourth, educators perceived the role of subject advisors to be limited to CASS moderation as they did not provide any developmental support to educators experiencing content gaps. Finally, educators saw the MIS as a money making scheme for certain educators and district officials. They claimed this was linked to corrupt practices during the appointment of tutors. The teachers did not have confidence in the appointment procedures used by the district for tutors.It can be concluded that the Matric Intervention Strategies in the two schools arenot likely to achieve the intended results as long as educators do not think thatthe strategies are addressing the problems they face. Another conclusion is that the Matric Intervention Strategies are seen as ‘quick fix’ responses to what arereally deep-seated and systemic problems in education. Given the findings of this study, it is recommended that the impact of Matric Intervention Strategies be the focus of a survey research for which a probability sample must be drawn that can generate findings that are generalisable across the participating target population. For the delivery of the MIS it is recommended that the weaknesses identified by educators of the two schools be further investigated so that new implementation plans can be developed.

- Description: The primary aim of this thesis is to provide a text-based literary study exploring the characters and themes created by K. Sello Duiker in the three novels, Thirteen Cents, The Quiet Violence of Dreams and The Hidden Star. Duiker’s work is significant because it highlights prominent societal challenges prevalent in post-apartheid society. By analysing Duiker’s novels one acquires a better understanding of this author, an understanding of the world that contributed to the creation of his texts and his contribution to South African literature. Insight into Duiker’s fictional world allows for a careful investigation of the prominent societal issues prevalent in Duiker’s work - a world riddled with violence, issues of sexuality and psychological distress. For this purpose this thesis is premised on the notion that underpinning K. Sello Duiker’s oeuvre is a central focus on dreams, sexuality and fantasy. Logically, therefore, the main focus of the study is specifically on the inner working of the characters’ minds and how they deal/ or are unable to cope with contemporary social concerns, often resulting in psychological turmoil and dysfunctionality. For this reason, prominent themes examined in this study are the interpretation of dreams, an exploration of sexuality and an examination of fantasy in the three novels. Psychoanalytic literary theory, with the main focus being specifically on the theories presented by Sigmund Freud is used as an analytic tool to read Duiker’s texts. Psychoanalytic theory is arguably the most appropriate for analysing Duiker’s novels as it allows one to investigate the characters’ psyches and the psychological effect of societal influences on these characters. In addition, one is also able to examine how the characters are able/ unable to deal with the trauma caused by the contemporary issues in society – issues of violence, sexuality and psychological distress. Thus, one is able to grasp an overall understanding of the characters’ behaviour and actions. Furthermore, the characters’ experiences are based on the behaviour and incidents of real people, people suffering from psychological dysfunctionality, sexuality issues and identity crisis. The first chapter discusses post-apartheid literature, and provides a brief background on Duiker, his works and his conception as a writer. Chapter two provides an overview of psychoanalytic theory and on the relevant theories of Sigmund Freud. Chapter three offers a reading of Thirteen Cents, a novel that pays particular attention to the lives of children living on the streets of Cape Town. In the next chapter The Quiet Violence of Dreams is examined with a special focus on Duiker’s experimentation with form in the construction of this novel. Aspects pertaining to sexuality and dreams are also examined. Chapter five pays particular attention to magical realism and fantasy in The Hidden Star.
