- Description: Malawi is divided into three regions, namely: Southern, Central and Northern regions. Each Region has an independent Water Board owned by Government to supply it with portable water. The Constitution of the Republic of Malawi 1994, Chapter 3, Section 13 recognizes public trust and good governance as some of the fundamental principles of National Policy and thereby promised to introduce measures which will guarantee accountability, transparency, personal integrity and financial probity and which by virtue of their effectiveness will strengthen confidence in public institutions. In order to improve service delivery and fulfill the stated constitutional imperatives, the Malawi Government issued the following statement in 2008, one of our cardinal agenda is reform aimed at changing the way things are done in the public service so that it becomes more efficient and responsive to the needs of all Malawians. As a Government we realize that no matter how brilliant plans and development agenda can be, they will be frustrated unless major reforms are initiated and implemented to facilitate required changes to support the development process. Major changes are necessary in values, beliefs, norms, attitudes and mindsets to help create an enabling environment for the effective management of reforms across the public service. We need to move away from the business as usual type of attitude and fully account for time that we are paid for from public funds if we are to join the prosperous nations (National Framework for Public Sector Management Reform, June, 2008).

- Description: The study was carried out to assess the extent to which the intervention of traditional leaders is effective in mobilising support for community development projects and to examine the perceptions that communities have about the role of the traditional leaders in development projects. The study has been guided by the critique of neoliberalism which exposes the negative effects of implementing the Structural Adjustment Programmes (SAPs) in Third World countries. The literature that has been reviewed has looked at the historical and political background of the role of chiefs and other traditional leaders in order to assess the nature of participation that is promoted through their involvement in development projects. An overview of the neo-liberal prescription and its critique has been made in order to expose the effects of the oil embargo of 1973 and the debt crisis of the 1980s on the economies of Third World countries in general and Malawi in particular. On the basis of evidence which has been gathered through a survey and focus group discussion, the study has found that the intervention of traditional leaders is very effective in mobilising communities for development projects. It has further been established that communities have high regard for their traditional leaders and that they perceive them as crucial role players in the conception and implementation of development projects. The study has however established that traditional leaders use unorthodox means such as threats of punishment to solicit the cooperation of the community members which in essence is counterproductive to the participatory approach to development.

- Description: The focus of the study was to evaluate the attitudes of midwives towards the implementation of the Choice on Termination of Pregnancy Act in the O.R. Tambo District hospitals in the Eastern Cape. There was no provision for termination of pregnancy (TOP) for unplanned pregnancy until 1994 when the Choice on Termination of Pregnancy (CTOP) Act was introduced. This act allowed any pregnant woman to request TOP when she wished for TOP. The midwives could voluntarily undergo training in TOP services and the designated institutions started offering TOP services, but stopped at a later stage. This resulted in overcrowding in health institutions which continued rendering TOP services. The researcher posed one question to be answered as: What are the attitudes of the midwives who are employed by health institutions in the O.R. Tambo District in the Eastern Cape Province towards the implementation of the Choice on Termination of Pregnancy Act? The aim of the study was to evaluate the attitude of midwives towards the implementation of the CTOP Act in the O.R. Tambo District hospitals. The objective of this study was to determine the attitudes of these midwives towards the implementation of these services in the O.R. Tambo District in the Eastern Cape Province. A quantitative descriptive design was used in this study. The population consisted of 150 midwives from two hospitals in the O.R. Tambo District. The sample consisted of 75 midwives; 30 midwives from Hospital 1 and 45 midwives from Hospital 2. Random systemic sampling was used in selecting the participants. Data were collected using a questionnaire developed by the researcher and approved by the supervisor and the University of Fort Hare Ethics Committee. In the study, using a sample of (n = 75), the attitude on the implementation of CTOP scale had high reliability of 0.81. Data were analysed with the help of a statistician using Statistix 8.1 software for Windows. Approval to conduct the study was obtained from the University of Fort Hare Ethics Committee, Eastern Cape Department of Health and Hospital 1 and Hospital 2 before the study was conducted. The dignity of the participants was maintained by explaining v the topic of the research study, the aim and objectives of the study, the method to be used for data collection and the significance of the study. The participants were allowed to ask questions and the name and telephone of the supervisor were provided in case they needed some clarity. Voluntary, written informed consent was obtained before the interviews were conducted. Privacy, anonymity and confidentiality were ensured and maintained through all the stages of the research process. The finding of this study was that the midwives employed by the health institutions in O. R. Tambo District Municipality displayed positive responses in the majority (n=11/61.1%) of 18 items in the questionnaire. Since the midwives in this study demonstrated a positive attitude towards TOP, it was recommended that the reason for stopping the TOP services in the concerned institutions should be investigated. The following are also recommended: Compulsory training of midwives should include aspects of reproductive epidemiology, in particular, the epidemiology of unsafe abortions. Training in TOP services should continue, so that there will be adequate number of midwives to provide the TOP services, and consideration of special remuneration for TOP providers. Employment of managers trained in TOP and voluntary training of managers working in TOP sections should be considered so that they may provide effective support to TOP providers. Formation of support centres for TOP providers at Provincial and National levels. Education of the community in prevention of unwanted pregnancies by means of contraceptives and indications for a need to provide TOP services, to prevent victimisation of the TOP providers. Availability of a toll free number for reporting victimisation of the TOP providers.

- Description: The objective of the study was to determine the avoidance-related behaviour, bleeding times and the quality of meat from sheep of different gender, breed (Dorper, Merino, and their crosses) and age groups, slaughtered at a commercial and municipal abattoir. Castrates and ewes of different age groups (1= <10months, 2= 11-12months, and 3= >12months) and breeds were used. From the commercial abattoir, 90 castrates and 110 ewes were used, while 66 castrates and 19 ewes were obtained from the municipal abattoir. Meat samples were obtained to determine meat colour, ultimate pH, temperature, cooking loss and tenderness. Correlations between bleeding times and meat quality variables were also determined. The two abattoirs differed in terms of technology and the procedures used, and this brought about different response behaviours in sheep at slaughter, bleeding times at exsanguination and the quality of meat produced. Animal-related factors (breed, gender and age classes) had no effect on the avoidance-related behaviour of sheep slaughtered at the commercial abattoir, while these factors affected those sheep slaughtered at the municipal abattoir. These factors also had an effect on the quality of meat produced at both abattoirs. Gender and weight of the animals had effects on the bleeding times at exsanguination at both abattoirs. Bleeding times did no correlate with any of the meat quality variables, but correlations among meat quality variables were observed. Avoidance-related behaviour, bleeding times, and the quality of mutton from sheep slaughtered at a commercial and a municipal abattoir was affected by breed, age, and gender.

- Description: According to the recent Statistics South Africa (2007), there are 668 176 children with disability between 6 – 23 years old of which 337 660 are males and 330 516 females in the Amathole District of the Eastern Cape. This number consists of schoolchildren with visual, auditory, physical, mental, multiple and non- specified types of disabilities. However, there are limited research studies on the challenges around opportunities for children to participate in variety of sporting activities within the school settings. The purpose of this study was to provide a more accurate picture of the barriers against inclusion of students with disabilities in sports, among the identified Special Schools in the Amathole district, Eastern Cape. Data collection involved interviews, questionnaire and participant observation methods. Results showed that 87 percent of the students with disabilities participated in one sport or the other with male student participating more (92.2 percent than the female participants (86.7 percent). Overall, the participation rate was 86.7 percent. Further analysis of data revealed that 44 percent female and 41.5 percent male students agreed strongly that sporting activities are beneficial to their health. 7.1 percent of the sample indicated that their disability prevented them from sports participation. The reported main barriers towards sports participation include; lack of trained personnel; lack of adequate funding; lack of cooperation from parents and guardians and inadequate facilities and equipment. Although students with disabilities were using the limited resources at their disposal to participate in sports, they need support to sustain their efforts.

- 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.

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: The objective of the study was to determine the effects of pre-slaughter conditions and anima-l related factors on bruising, creatine kinase (CK) and beef quality. Three hundred and twenty one cattle from three breeds (108 Bonsmara, 130 Beefmaster and 83 Brahman) were used in this study. The animals were grouped according to age categories as follows; Group 1(16months), Group 2 (18months) and Group 3 (24 months). Blood samples for CK determination were collected at exsanguisation using disposable vacutainer tubes. The Muscularis longisimus thoracis et lumborum (LTL) muscle was used to determine beef colour (L,* a* and b*) and ultimate pH. Significant P (<0.05) breed effects were observed on bruising score and CK levels with Bonsmara breed having the highest percentage (80 percent) of bruising score and higher CK (705.3±80.57) values. The higher CK levels were also in winter season. The effect of breed, sex and age at slaughter on meat quality (pHu, L*, a*, b*) was also observed. There were positive correlations between distance travelled and meat quality, while there was no relationship observed between CK and distance travelled. Therefore, it was concluded that animal related factors had an effect on meat quality and CK levels.

- Description: Teenage pregnancy is a worldwide phenomenon. World Health Organisation (2009) reports that teenage mothers between the ages of 15-19 years account for 11% of births recorded worldwide. In South Africa it has been estimated that teenagers aged 17-19 account for 93% of all teenage pregnancies. A large proportion of these adolescents return to school after giving birth. Research has shown that there is a great deal of controversy about not only pre-marital sex, but also concerning whether teenage mothers should be allowed back in school at all. The aim of this study was to gain some insights into the lived experiences of teenage mothers in schools with particular reference to how they cope with school work and the responsibilities of motherhood. A case study of four teenage mothers who returned to school after giving birth was carried out. In-depth phenomenological interviewing designed to elicit the voices of the selected adolescents was done. There were five main findings. First, all four teenagers were minors, under the age of 18 when they gave birth. Two of them were even under the statutory age of consent. Second, upon return to school, teenage mothers experienced stigmatisation from peers and teachers and this forced them to continually negotiate their dual identities as mothers and learners. Third, teenage mothers experienced psychological emotions of stress; low self-esteem; shame and depression. Fourth, they also had sociological experiences in the form of material, financial and social support from family and friends. In some cases they experienced rejection from peers and abandonment by boyfriends who had made them pregnant. Some educators discriminated against and ridiculed teenage mothers. Fifth, teenage mothers reorganised their lives after childbirth and established routines that enabled them to cope with the demands of school work and the responsibilities of motherhood. iii The study concludes that, although viewed with scepticism by sections of the community and some educators, and given that some pregnancies are a result of abuse and unequal power relations between men and women in society, the policy of allowing teenage mothers back to school after giving birth gives them another chance to re-focus their lives. It is recommended that the voices of teenage mothers who return to school after childbirth should be taken into account to inform any planning for future policies on teenage pregnancy by schools and the state. It is further recommended that all educators should also be trained to be able to assist the teenage mothers instead of alienating them. There should also be counselling services available for the teenage mothers to enable them to deal with psychological and sociological problems they might encounter. For further research, students from different backgrounds should be the target of similar research. Another area of research should focus on academic performance of teenage mothers who return to school after giving birth. Lastly, there should be research that seeks to link what is taught in the Life Orientation curriculum and voices of teenage mothers.

- Description: This study focuses on child participation in the evaluation of the school nutrition programme. It investigates the SNP exclusively from Grade 4 learners’ perspectives. The main significance of it is that many evaluations of the SNP focus on other stakeholders’ perspectives. The study intends to explore effective methodologies and tools for conducting research with children. Furthermore, this study seeks to contribute to the existing literature on the importance of children’s participation in matters concerning their lives. The study seeks to explore three research questions. Firstly, it seeks to explore how Grade 4 learners describe the purpose of the SNP. Secondly, how do the Grade 4 learners describe their day to day experiences of the SNP. Lastly, how do the Grade 4 learners describe the impact of the SNP. Through this research experience, the study hopes to illuminate recommendations to better align policy and programme design with stated intentions. The study is qualitative, and based on a case study design. The central analysis focuses on eight case studies, each representing the experience of one Grade 4 learner, within the context of two selected schools in the rural areas of Mqanduli. This study underscores the literature on school nutrition programming. Despite severe implementation shortfalls, learners still consider the nutrition programme to be an important aspect of their school day. The experience and analysis of learners in regard to the SNP was relatively consistent. Learners consistently experience the SNP as contributing to temporary hunger alleviation thus enhancing learning capacity. Furthermore, they regarded the SNP to have had positive impact towards enhancing their school attendance and punctuality, and mediation between their home and the school life. The study supports the literature that suggests that, while school nutrition programming represents one of the most promising policy tools for serving the rural poor, unless it is carefully designed to reflect the known requirements of school feeding, the results can be limited. This study further suggests that if a programme is poorly implemented, it runs the risk of undermining the intended policy aims rather than contributing towards their attainment. The study further acknowledges child participation in policy and programme decisions concerning them. The study concludes by making a number of policy and implementation suggestions that may better align policy and practice to the specific context of the rural poor in Mqanduli. While these case studies are too few to suggest generalisability of results, it is hoped that these recommendations will be studied for wider application.

- Description: The aim of the study was to evaluate school children’s attitudes towards Physical Education in selected Mutare city schools. In order for the children to benefit from the Physical Education program, the study hypothesized that children must develop the right attitudes towards Physical Education. This observation has also been emphasized in other studies that children, who possess the right attitude towards Physical Education, develop positive attitudes towards physical activities. This suggestion has also been reported by Portman, (2003) and McKenzie (2003) that one of the benefits of Physical Education is sustained participation in physical activities outside the school. This study involved 400 children from Mutare Junior, Chancellor, Zamba, Dangamvura, Sakubva, Chikanga, Mutanda and Murahwa Primary Schools in Mutare city. The children’s age ranged between 12 - 14 years old. The primary data were collected from questionnaires, interviews and focus group discussions, while secondary data were based on related literature review. The results indicated that the teacher, curriculum content and delivery, the learning environment, siblings, type of school, location of residences, proximity of facilities and support from parents were some of the factors associated with children’s attitudes towards Physical Education and Physical Activity at school and home respectively. In many ways, these factors affected children’s sustainable participation in physical activities after school.

- Description: A study to assess the potentials of some commensal bacteria that belong to Staphylococcus, Acinetobacter and Stenotrophomonas genera as reservoirs of antibiotic resistance determinants in the environment of Nkonkobe Municipality of the Eastern Cape Province, South Africa, was carried out using standard microbiological and molecular techniques. A total of 120 Staphylococcus isolates which consisted of Staphylococcus haemolyticus (30%), Staphylococcus aureus (23.3%) from pig; Staphylococcus capitis (15%) from goat; Staphylococcus heamolyticus (5%) and Staphylococcus xylosus (15%) from cattle and other Staphylococci (11%) from dead chicken and pigs were isolated. About 23.3% of these isolates were coagulase positive and 76.7% were coagulase negative. This difference in prevalence along coagulase production divide was statistically significant (p < 0.05). Eighty-six Acinetobacter species (Acinetobacter baumannii/calcoaceticus and Acinetobacter haemolyticus) were also isolated from Alice and Fort Beaufort towns samples, while 125 Stenotrophomonas maltophilia isolates were from grass root rhizosphere (96%) and soil butternut root rhizosphere (4%). Between 75-100% of the Staphylococccus species were resistant to Penicillin G, tetracycline, sulphamethaxole and nalidixic acid; about 38 % were methicillin resistant, consisting of 12.6% methicillin resistant Staphylococcus aureus (MRSA) from pig and a total of 12% vancomycin resistant were observed. Also, 12% of the isolates were erythromycin resistant while 40.2 % were resistant to the third generation cephalosporin, ceftazidime. The antibiotic resistance genes vanA, VanB, eryA, eryB, eryC were not detected in all the phenotypically resistant Staphylococccus species, but mec A gene and mph genes were detected. In the Acinetobacter species, a wide range of 30-100% resistance to penicillin G, ceftriazone, nitrofurantoin, erythromycin, and augmentin was observed. Polymerase chain reaction (PCR) revealed the presence of Tet(B) and Tet(39) genes in these species, while Tet (A), Tet(M) and Tet(H) were absent. Also, 9.3% of the Acinetobacter species showed phenotypic production of extended spectrum beta lactamases (ESBLs) while 3.5% were positive for the presence of blaCTX-M-1 genes. The Stenotrophomonas maltophilia isolates showed varying resistance to meropenem (8.9%), cefuroxime (95.6 %), ampicillin-sulbactam (53.9%), ceftazidime (10.7%), cefepime (29.3 %), minocycline (2.2%), kanamycin (56.9%), ofloxacin (2.9%), levofloxacin (1.3%), moxifloxacin (2.8%), ciprofloxacin (24.3%), gatifloxacin (1.3%), polymyxin B (2.9 %), cotrimoxazole (26.1%), trimethoprim (98.6%), aztreonam(58%) and Polymyxin B (2.9 %). The isolates exhibited significant susceptibility to the fluoroquinolones (74.3-94.7 %), polymycin (97.1%) and meropenem (88.1%). Only sul3 genes were the only sulphonamide resistance gene detected among the trimethoprim-sulphamethoxazole resistant isolates. The observed multiple antibiotic resistance indeces (MARI) of >2 for Staphylococcus species, Acinetobacter species and Stenotrophomonas maltophilia suggest that they have arisen from high-risk sources where antibiotics are in constant arbitrary use resulting in high selective pressure. The presence of tetracycline resistance genes in Acinetobacter species justifies the observed phenotypic resistance to oxytetracycline and intermediate resistance to minocycline. High phenotypic resistance and the presence of some resistance genes in Staphylococcus species is a possible threat to public health and suggests animals to be important reservoirs of antibiotic resistance determinants in the environment. Indiscriminate use of antibiotics induces this kind of antibiotic resistance and should be discouraged. Personal hygiene is encouraged as it reduces the load of Acinetobacter species contacted from the environment that may be difficult to control. Commensal Stenotrophomonas maltophilia are as important as their clinical counterparts due to their roles in opportunistic infection, antibiotic resistance and their associated genes, especially sul gene. Personal hygiene is hereby advocated especially when in contact with soil, plants and plants’ rhizospheric soil.

- Description: Although food insecurity is said to have decreased in South Africa in the past years particularly at the national level, however, at household level a substantial proportion of households remains at risk of food insecurity and are experiencing hunger particularly in the Eastern Cape Province were poverty is rife. Food insecurity in the Eastern Cape Province is attributed to the fact that agriculture, the mainstay of the rural economy is no longer given the value that it should carry, does not help the situation. Despite much research on food (in) security in South Africa, the link between poverty and household food security is not at all clear. This study seeks to fill this gap specifically by looking at the linkages in the main between food security and poverty especially in the community level. Amidst the various programmes and initiatives that are in place in South Africa, there is continual prevalence of food insecurity facing the majority of South African households. The major aim of this study was therefore to examine the impact of one of these programmes, the Zanyokwe irrigation scheme in enhancing food security not only for the farmers but also for the surrounding communities. This study adopted a qualitative approach to research. The study unearthed that even though Zanyokwe irrigation scheme has played an indispensable role in enhancing food security for the smallholder farmers and the community at large challenges such as market challenges, road infrastructural issues, land tenure issues, lack of proper coordination amongst the farmers as well as farmer empowerment are a major limitation to the growth of the irrigation scheme and the farmers. Thus, the study recommended that farmer support services, training, agriculture subsidies, improved infrastructure as well as addressing market related challenges will go a long way in reducing the plight of the Zanyokwe farmers as well as enhancing food security

- Description: Stenotrophomonas maltophilia is increasingly emerging as an opportunistic pathogen of global concern. Due to its inherent resistance to several classes of antibiotics including carbapenems and its ability to acquire mobile resistance elements, treatment of infections caused by S. maltophilia is a constant challenge for clinicians. Trimethoprim-sulphamethoxazole (TMP-SMX) is the generally accepted antibiotic of choice for the treatment of infections caused by this organism, but resistance to the drug is increasingly being reported; hence, the need for alternative therapeutic options. In this study, the antimicrobial susceptibility profile of 110 commensal S. maltophilia isolates obtained from Nkonkobe municipality, Eastern Cape Province, Republic of South Africa was investigated. Twenty-one antibiotics including TMP-SMX and the newer fluoroquinolones; levofloxacin, gatifloxacin and moxifloxacin were included in the antibiotic panel. About 63.4 percent of the isolates were susceptible to TMP-SMX with a resistance rate of 28.2 percent. The fluoroquinolones were more effective with susceptibilities ranging from 76 percent to 94.7 percent. Resistance to the fluoroquinolones ranged from 1.3 percent to 2.7 percent. Levofloxacin was the most effective fluoroquinolone tested. Phenotypic dectection of extended spectrum β-lactamases (ESBLs) showed double disc synergy test (DDST) positivity in 59.5 percent of the isolates. Cefepime was the most sensitive indicator cephalosporin in the DDST with 77.3 percent of suspected ESBL-producing isolates showing cefepime-clavulanic acid synergy. Isolates exhibited nine different ESBL phenotypes, however, PCR amplification of the bla genes revealed four isolates that possessed genes belonging to the CTX-M group (CTX-M-1 and CTX-M-8 groups). ESBL genes are usually carried on mobile elements such as plasmids and transposons which may also bear genes that mediate resistance to aminoglycosides, tetracyclines, TMP-SMX and fluoroquinolones. ESBL positive isolates appeared more susceptible to the fluoroquinolones compared to TMP-SMX but there was no significant relationship between ESBL production and susceptibility to these drugs (p > 0.05). The newer fluoroquinolones are a possible alternative treatment option for S. maltophilia infections in this environment but further studies and clinical investigations are needed to determine the in vivo efficacy of these drugs.

- Description: The overall objective of the study was to investigate the relationship between male circumcision status and HIV infection in men from Salima district in Malawi. A cross-sectional survey-based study of men aged 15 years or more was conducted at three sites in Salima district, each of which targeted 90 participants, half of whom were circumcised and the other half uncircumcised. These participants had already decided on their own to visit HIV Testing and Counseling centres at these sites to know their HIV serostatus. Consenting men were drawn into the study using quota sampling, interviewed through a structured questionnaire in local language and tested for HIV during January and March 2011. Measures of association were performed using analysis of contingency tables and Pearson’s chi-square tests or Fisher’s exact tests for comparison of proportions in STATA version 11.0 and PASW Statistics 18.0 software. Unadjusted odds ratios were used to approximate the direction and strength of association. Further, a multivariable logistic regression model was fit to determine which other variables were significantly associated with HIV infection. The study was approved by University of Fort Hare Interim Research Ethics Committee and National Health Sciences Research Committee in Malawi. The overall prevalence of HIV infection was 11.5 percent. However, it was less than half in circumcised males (7.4 percent) compared with uncircumcised counterparts (15.6 vi percent). While Fisher’s exact test revealed a borderline statistically significant association between male circumcision status and HIV infection (p 0.055), Pearson’s chi-square test showed a stronger significant association between the two variables ( p 0.036). The strength of the association was manifested by the odds of HIV infection being roughly 0.43 times lower for circumcised males than their uncircumcised counterparts with a 95 percent confidence interval of (0.20 0.96). Although the association was maintained after controlling for some variables, it lost statistical significance when adjusted for other variables. A multivariable logistic regression revealed that three other variables had significant associations with HIV infection and these were: falling in the age group of 25 years or more (OR 4.69; p 0.020), having had sex with an HIV positive partner (OR 12.15; p 0.000) and having contracted a sexually transmitted infection (OR 3.25; p 0.032). Male circumcision status is significantly related to HIV infection. Although the study involved a small sample size and undertaken in one district in Malawi, the finding is consistent with existing clinic-based findings in literature that indicate a lower risk of HIV infection in circumcised males than in uncircumcised males. Consequently, male circumcision could be considered if it can prove to be a public health intervention in the Malawi context aimed at reducing the risk of uncircumcised males becoming infected by HIV.

- Description: The purpose of the study was to explore the relationship between WFC and stress with Conscientiousness which is part of the Big Five personality Traits Model in moderation. The study was undertaken in the South African Police Service members in Alice town in the Eastern Cape. The study was based on a sample size of eighty four (n=84) out of 134 (N=134) police officers. A simple convenient random sample was used to sample participants. With the use of descriptive, correlation and inferential statistics the finding revealed instead that Conscientiousness has no significant relationship with WFC at (r= 0.02792, p= 0.8022) also Conscientiousness had no significant relationship with stress at (r= -0.04465, p= 0.6885). Overall, after separating the group according to those that scored low and those that scored high on conscientiousness scale, the study found the group low in conscientiousness not significantly correlated with WFC and stress (r= -0.02263, p= 0.9414). and the group with a high conscientiousness the study revealed a high significant relationship for police officers that scored high on Conscientiousness at (r= 0.40119, p< 0.00). The group low in conscientiousness has no correlation between WFC and stress thus different values of conscientiousness cause a change in the relationship between WFC and stress. Thus those who are low in conscientiousness do not have a relationship between WFC and stress. A call is made to the SAPS as an institution to consider prioritizing personality trait particularly applicants that score low on conscientiousness personality test during recruitment and selection of new police officers to avoid the outcomes associated with the nature of police work.

- Description: The study emanates from the constitutional imperatives with regard to the role of local government in community development. The notion of cooperative governance is envisaged in the South African Constitution which stipulates that all spheres of government must adhere to the principles of cooperative government and must conduct their activities within the parameters prescribed by the Constitution. The purpose is to support and strengthen the capacity of the local governments to manage their own affairs and to perform their functions. The basic values and principles governing public administration entail that: it must be broadly representative of the people of South Africa in order to redress the imbalances. The existing gaps in the legislation on decision making power at the local level of the municipality, be it in a ward committee or sub council, have not been adequately addressed in the post 1994 democratic dispensation. It is in this context that this study seeks to address these gaps and obstacles, and contribute to the design and development of a decentralized cooperative governance model, specifically to the six metropolitan municipalities and also provide a basis for further research. The findings of the research could be adapted as a national policy in the empowering of municipalities through the dispersal of democratic power which is an essential ingredient of inclusive governance. Based on a case study of six metropolitan municipalities, the research is intended to contribute to the development of empirically grounded; praxis and practical guideline in decentralized cooperative governance which can be adopted and institutionalized in public administration. It is believed that a study of decentralized cooperative governance adds value in that it seeks to link decentralized power and local development. Rather than civil society organisations being seen as adversarial, a creative partnership with the state in local development is crucial. This political assimilation is critical in the construction of democracy through fusing the substantive values of a political culture with the procedural requisites of democratic accountability. This serves to fragment and disperse political power and maintain a system of checks and balances with regard to the exercise of governmental power. The capacity for innovation, flexibility and change can be enhanced at the local level, and it is a cliché that local decision making is viewed as more democratic in contrast to central, top-down decision-making processes. A syncretistic model for local government based on the political adaptation of political and inclusive decentralisation is outlined.

- Description: The aim of this study was to prepare composite materials based on titanium dioxide (TiO2) and silicon dioxide (SiO2), and to evaluate their photo-catalytic and antimicrobial properties. Carbon and nitrogen doped TiO2nano-particles were prepared via a sol gel synthesis, which is a simple hydrolysis and condensation technique. In situ doping was carried out using glucose and urea as carbon and nitrogen sources respectively. Doping increased the spectral response of titanium dioxide photo-catalyst, allowing it to utilise the visible region which is much wider than the UV region (about 40 % of the solar spectrum), thus making it a more efficient photo-catalyst. The carbon and nitrogen doped TiO2-SiO2nano-particles were immobilized on glass support material to allow for easy separation of the spent photo-catalyst after the photo-degradation process. Tetraethyl orthosilicate (TEOS) was employed as both a binder and precursor for silicon dioxide. A mixture of TiO2 and TEOS in a 1:1 ratio was allowed to polymerize on a glass support which had been treated with hydrofluoric acid to introduce OH groups. The prepared photo-catalytic material was characterized by FT-IR, XRD, DRS, TEM, EDX, and BET analyses. Carbon was found to be more effective as a dopant than nitrogen. It brought about a band gap reduction of 0.30 eV and a BET surface area of 95.4 m2g-1 on the photo-catalyst as compared to a gap reduction of 0.2 eV and surface area of 52.2 m2g-1 for nitrogen doped TiO2. On the other hand, introduction of SiO2 allowed utilization of visible light by the TiO2-SiO2 nano-composite leading to an improved rate of photo-degradation of both methyl orange and phenol red. However, the immobilization of TiO2 on support material made it less effective towards inactivation of E. coli ATCC 25922 bacterial cells when compared to powdered TiO2 which was able to inactivate about 98 % of the bacterial cells within an hour of treatment.

- Description: More and more people worldwide are becoming “carbon conscious”. This means they are becoming increasingly aware of the imminent adverse effects of global warming. Of late there has been an urgent drive for governments to be on the forefront of all carbon mitigation initiatives. One such drive involves the United Nations Framework Convention on Climate Change whose parties have been meeting regularly under the banner of Conference of Parties (COP) since 1995. At this conference, parties to the convention review progress made in dealing with climate change. Also key to the deliberations in such meetings are better ways of developing cleaner “carbon free” energy sources. Energy sources of this nature are commonly known as renewable energy sources. In essence global energy trends are constantly moving towards development of more renewable energy sources. It is an undeniable fact that some of viable renewable energy sources especially those with bulk capacity are usually located remotely from load centers. This inevitable reality necessitates the construction of long distance bulk power transmission corridors to link generation sites with load centers. Due to its many inherent advantages over High Voltage Alternate Current (HVAC) for long distance power transmission, High Voltage Direct Current (HVDC) is gradually winning the favor of many utilities. In fact, recent advances in HVDC technology have encouraged many utilities to explore the possibility of harnessing remotely located renewable energy sources which would have otherwise not been viable with HVAC transmission. Through the unfortunate and inevitable phenomenon known as corona effect, overhead HVDC conductors suffer real power losses to the air dielectric surrounding them. Through corona, part of the energy carried on the transmission line is expended through ionization and movement of charges in the air dielectric. This study combined physics, mathematical as well engineering concepts to review corona phenomenon around HVDC lines with specific emphasis on space charge generation and motion within ionized DC fields as well as the influence of temperature on corona discharge or power loss. Also, unlike HVAC, performance of an HVDC system relies heavily on the availability of a reliable and robust telecommunication system. One of the key ways of ensuring reliability of a telecommunication system is by making sure that reliable power supplies are in place to power remote repeater stations. A novel concept of quasi-autonomous corona-based power supply (or QC power supply in short) that works on the principle of magnetohydrodymic (MHD) power generation was developed. A small scale experiment was then designed to assess the feasibility of such power supplies. The experiment was conducted with DC supply of a maximum rated voltage of 30 kVDC and generated up to 6 VDC at an optimum ambient temperature of 23°C. These results have confirmed that with further development QC power supplies have the potential of proving reliable power to remotely located repeaters or any other small critical loads along the stretch of the HVDC transmission line. Practical HVDC transmission systems operate voltages in the excess of 500 kV. By linear extrapolation of the above mentioned results; one would expect to yield up to 100-, 120- and 160-VDC from a 500-, 600- and 800- kV HVDC system, respectively. Although the study succeeded in conceptualizing a CMHD idea upon which the novel QC power supply was developed, quite extensive and rigorous design, modeling, prototyping and experimentation processes are still required before the first QC power supply can be commissioned on a practical HVDC line

- Description: More and more people worldwide are becoming “carbon conscious”. This means they are becoming increasingly aware of the imminent adverse effects of global warming. Of late there has been an urgent drive for governments to be on the forefront of all carbon mitigation initiatives. One such drive involves the United Nations Framework Convention on Climate Change whose parties have been meeting regularly under the banner of Conference of Parties (COP) since 1995. At this conference, parties to the convention review progress made in dealing with climate change. Also key to the deliberations in such meetings are better ways of developing cleaner “carbon free” energy sources. Energy sources of this nature are commonly known as renewable energy sources. In essence global energy trends are constantly moving towards development of more renewable energy sources. It is an undeniable fact that some of viable renewable energy sources especially those with bulk capacity are usually located remotely from load centers.

- Description: In South Africa, it is evident that women are uniformed of their essential human rights, especially their inheritance and succession rights, including protection of such rights. Human rights are international norms that protect individuals everywhere from the states’ political, legal and social abuse. Human rights are entitlements which human beings have in order to enhance their human condition. They are the fundamental entitlements or minimum standards to be met for individual so that they live with dignity. This study focused on discrimination of women under customary law in South Africa with reference to inheritance and succession. The study validated the findings of other researchers on the impact of cultural practices on women’s rights to inheritance and succession. In addition the findings revealed that efforts t eliminate traditional practices, should foremost come from men and from communities that hold such destructive attitudes towards women. The outcomes and recommendations of this study would assist the government and other institutions to adopt effective measures to empower women and especially educate them so that they can assert and defend their human rights

- 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.
