- Description: This study involved evaluating the extent to which universal access to quality grade R was realised by 2012 in Cofimvaba education district in the Eastern Cape Province. The evaluation was done through the implementation of goal 11 of the Education Sector Strategy - the Action Plan to 2014, revised to 2019. It further sought to find out whether universal access to grade R occurred to all learners who registered for grade 1 and whether the quality of grade R had improved between 2010 and 2012 in Cofimvaba education district. Improving the quality of grade R in this study included an assessment of the level of qualification of grade R practitioners and an improvement of the quality of grade R tuition through the use of textbooks, workbooks and resource packs supplied to grade R by the Department of Basic Education (DBE). The study used both the qualitative and quantitative methods. Questionnaires were used as data collection methods from grade R practitioners and grade 1 teachers. The respondents in this study consisted of twelve grade R practitioners, ten grade 1 teachers and two officials from Cofimvaba district office. The findings of this study revealed that the universal access to grade R, calculated from grade 1 learners who received formal grade R, was not achieved over the three-year period 2010-2012; albeit the target of grade 1 learners who should have received formal grade R by 2012 was a mere 50 percent. The percentage of grade R learners who received access to the required textbooks fell below the expected target of 100 percent. Although 77.61 percent does not signify bad performance, the non-attainment of 100 percent access to the required textbooks could not be acceptable because the absence of textbooks meant that effective teaching and learning could not have taken place. However, these findings uncovered that the supplied textbooks and workbooks were high quality learning and teaching materials. The findings also uncovered that the ECD-grade R practitioners, at the time, had the necessary work experience and limited qualifications as a means to teach the grade R classes. A pressing matter for the Department was the improvement of conditions of service for practitioners; their professionalisation as well as further improvement of their qualifications. It was revealed, through this study, that there was a slight improvement in the universal access to grade R; however, the quality of grade R still needed attention especially in so far as the provision of suitably qualified practitioners is concerned.

- Description: The Council of Australian Therapeutic Advisory Groups (CATAG) (2013) define a Pharmaceutical and Therapeutics Committee (PTC) as a ‘multi-disciplinary team committee with a commitment to the overall governance of the medicines management system in health service organizations to ensure the judicious, appropriate, safe, effective and cost-effective use of medicines’. The multi-disciplinary team includes the health care providers, who are actively participating in the health care systems, such as doctors, pharmacists, nurses, administrators, finance officers, quality improvement managers and other staff members who participate in the medicine use processes according to their knowledge and skills. The major role of this committee is to evaluate and promote rational drug use by health care providers and consumers. In addition, this committee is responsible for developing systems and strategies to prevent adverse medicine reactions and medication errors, enhance rational prescribing and dispensing, provide educational activities and ensure the use of quality and cost-effective medicines. This is a cross-sectional study that was aimed at exploring the structure, activities and functions of public sector institutional Pharmaceutical and Therapeutics Committees (PTC) in the Eastern Cape (EC) Province in South Africa (SA). The primary objectives of the study were to (i) investigate and describe the structure, functions and the activities of the institutional PTCs, and (ii) explore and describe the perception of PTC secretariats on the functionality of the institutional PTCs. A purpose-designed questionnaire including both quantitative and qualitative aspects adapted from other international studies was piloted prior to being used for data collection. The secretariats of the institutional PTCs were requested to complete the questionnaire. Data were analysed using descriptive statistics for the quantitative aspects and thematic analysis for the qualitative component of the questionnaire. Data collection commenced after approval by the relevant ethics committees had been granted. The findings of the study reflected that the majority of the PTCs in the EC province, SA are district/sub-district PTCs which are a cluster of a number of health care institutions in close proximity. The PTC members were appointed by the executive authority as recommended by the literature and other guiding documents. As expected the nurses were dominant as the members of the PTCs in these district/sub-district PTCs. The secretariats were the pharmacists where pharmacists were available and chairperson were doctors. These findings correspond to the recommendations by the National Department of Health PTC policy (2015) and the studies conducted in other countries. A number of PTCs had sub-committees formed e.g. ABC analysis review committee, medicine utilization evaluation (MUE) committee and pharmacovigilance committee to optimise their functionality. Out of 15 PTCs only five PTCs with sub-committees reported functions and interventions, establishment of policies and SOPs. The rest had no outcomes or interventions reported. Poor production of policies and SOPs was observed which differs from other countries’ PTCs. The focus of sub-committees in other countries is the development of formulary and policies related to medicine use. These findings pose a question regarding the functionality and effectiveness of the existing institutional PTCs in the province. In addition, the basic documents that are required to run the PTC were unavailable in a number of PTCs. Barriers to the functionality of PTCs were reported i) Lack of pharmacists and training in PTCs. ii) The rural nature of the EC province and iii) Unavailability of resources including lack of re-imbursement of personal costs. These findings reveal that budget allocation for institutional PTCs is crucial for their functionality. It can be concluded that in the EC province the institutional PTCs which are active and effective are low in number and do not cover all geographical areas. Secondly there is a need for training and educating the PTC members on the role of the PTC members, role of sub-committees, development of policies, SOPs and the basic documents for the functionality of the committee. It is also important that during training the monitoring and evaluation of the effectiveness of the committee is emphasised. Therefore, the choice of the PTC objectives should be measurable as they can assist as indicators of effectiveness. Support by the executive authority has been observed.

- Description: Research indicates that many children finish primary school in Southern Africa still reliant on inefficient counting strategies. This study extends the research of the South African Numeracy Chair project to early mathematics intervention with Grade 2 learners. It investigated the possible adaptation of the Mathematics Recovery programme to facilitate learner progression in early arithmetic strategies. This study aimed to investigate the possibility of adapting the Mathematics Recovery programme for use in a whole class setting, and to research the effectiveness of such an adapted programme. This study also aimed to investigate the extent of the phenomenon of unit counting and other early arithmetic strategies used in the early years in Zambia. This study was conducted from an emergent perspective. A review of the literature indicated that children who become stuck using unit counting face later mathematical difficulties, and that teacher over-emphasis on unit counting in the early years of schooling may be a contributing factor. This study used a qualitative design research methodology that consisted of a preparation phase, teaching experiment and retrospective analysis. The context of this teaching experiment was a seven week after-school intervention with a class of Grade 2 learners aged seven to eight in a rural Zambian primary school. Data collection and analysis focused on video recordings of a sample of 6 learners. The experimental teaching content focused on the Early Arithmetic Strategies aspect of the Mathematics Recovery programme. Although limited by time and research focus, this study found that all learners made some progress in early arithmetic strategies, and indicates that the Mathematics Recovery programme has potential for adaptation for early intervention in whole class teaching to address the mathematical education challenges in Zambia and beyond. This study also found that unit counting predominated in the sample learners, but that strategies were not yet entrenched, indicating this was a suitable age for early intervention. This study makes methodological contributions to a growing body of research into the adaptation of the Mathematics Recovery in Southern African contexts and suggests avenues for possible further research.

- Description: It is worth raising the question, why are wild edible plants (WEPs) which are rich in diverse nutrients and widely abundant underutilized despite the increasing rate of undernourishment in poor regions? One reason is that their culinary uses are not quantified and standardized in nutrition surveys, and therefore, they are not properly included in household diet intensification and diversification across regions and cultures. Active steps are needed to bridge this gap. This paper outlines the constraints to including WEPs in nutritional surveys as the lack of standard ways of food identification of diverse WEPs, lack of specific food categorization and therefore difficult dissemination across regions and cultures. As a way forward, a functional categorization of 11 subgroups for WEPs is introduced and discussed. In labeling these sub-food groups, the paper advocates that more WEPs food items and culinary uses should be enlisted during household nutrition surveys. Food researchers could then capitalize these enlisted species and disseminate them to promote diverse food use of WEPs in other regions where they exist but are not utilized as food.

- Description: Populations of small prey species (< 92 kg) can be regulated by competition, habitat-mediated responses, climate change, disease and predation. Populations of small prey species have declined in the Addo Elephant National Park Main Camp Section since the reintroduction of apex predators (lion and spotted hyaena). One possible explanation is predation by lion and spotted hyaena. However, small prey species are not generally considered preferred prey items of these predators, hence their contribution to predator diets needs to be explored. Global Positioning System (GPS) cluster analysis has emerged as a viable approach to locate lion kills for lion diet estimation in AENP, however this technique is known to bias diet estimates to large prey species. Understanding the impact of lion predation on populations of small prey in Main Camp therefore requires better estimates of lion diets. This study investigated the potential underestimation of small prey species in lion diet estimates by combining the data from scat analysis and carcasses located at GPS clusters. The adjusted lion diets were then used to investigate if the impact of lion predation could explain declines in small prey, by relating lion prey preferences to prey population trends in Nyathi. Using the results from Nyathi, it could then be inferred whether lions could have been responsible for the declines observed in Main Camp. Six GPS-collared lions provided location data used to construct individual movement paths, along which spatio-temporal clusters of GPS locations (n = 4896) were identified for ground investigation. Carcasses (n = 643) were recorded at the GPS clusters and scats (n = 256) were collected at GPS clusters with or without carcasses. Data from the located carcasses and scat collections were then used to create a history of feeding events for each collared lion in Main Camp-Colchester and Nyathi from a) carcasses alone or b) a combination of scats and carcasses, based on an estimated short and long lion throughout period. Relative prey availability was estimated based on camera trapping in Nyathi in high lion, low lion and no lion use areas, as lions may encounter some prey species more than other prey species. Jacobs’ index prey preference was used to investigate the importance of prey species to lion diets at three landscape scales: 1) Nyathi, 2) lion UD and 3) core lion UD. Lastly, prey population trends were investigated in Nyathi to provide an indication of possible changes in prey populations. Large prey species dominated the adjusted diets of lions in Main Camp-Colchester and Nyathi. However, when comparing the GPS carcass-derived lion diet estimate to the combined lion diet estimate, small prey were underestimated more often than large prey in the GPS carcass-derived lion diet estimate. Missed feeding events were therefore a function of prey body size. In addition, missed feeding events were also representative of the lion diets based on carcasses, with the tendency for species more often consumed to be missed more often in the diet record. However, even though small prey species were underestimated, they represented the minority of species consumed by lions and were predominantly avoided by lions in Nyathi. Lion prey preferences thus did not correlate to the declines in small prey species in Naythi, suggesting other potential drivers are important for small population trends in Nyathi. Lion predation cannot be ruled out as a driver of the decline in small prey species in Main Camp, due to different ecological conditions (e.g. vegetation density) in Main Camp compared to Nyathi, during the observed small prey population declines. Lion prey preferences in Nyathi revealed fine-scale variations in species specific preferences by lions, as well as site-specific differences in prey preferences when compared to published lion prey preference meta-analyses. These findings suggest that metaanalysis studies should be used as a guideline from which hypotheses about local predatorprey interactions can be developed rather than as an absolute measure of prey preference.

- Description: Rationale: There is limited research available in South Africa that explores the breastfeeding experience among adolescent mothers; most of the studies were conducted in developed countries. One such study relating to the above mentioned developed countries stated that social and commitment factors influence the decision to breastfeed by adolescents. Furthermore, while adolescent mothers appreciate the benefits of breastfeeding, pain, public exposure and perceived complexities related to breastfeeding create barriers for them. The researcher was unable to ascertain if similar ambiguities exist among adolescent mothers in South Africa, and in the Eastern Cape (EC) in particular with its high rates of adolescent pregnancy. In order to attempt to develop age appropriate recommendations to assist adolescent mothers with their breastfeeding journey, the researcher undertook this research study to answer the following question: What are the breastfeeding experiences of adolescent mothers in the Nelson Mandela Bay Heath District (NMBHD)? Aim: The research aim was to determine the experiences of adolescent mothers regarding breastfeeding in NMBHD. Methods: The study implemented a qualitative research approach. To enhance the design, the researcher utilised an explorative, descriptive and contextual research design. The ethical principles that guided this study were autonomy, nonmaleficence, beneficence and justice. Fourteen adolescent mothers, attending PHC facilities in the NMBHD participated in the study. Participants were chosen from a purposive sampling technique and data were collected from semi-structured interviews, compromising of individual interviews. The researcher analysed the data using the using the eight steps of the Tesch analysis technique. Data was also analysed by an independent coder. Results obtained from the Tesch approach were compared to that of the independent coder results. Thereafter, the major themes and sub-themes that related to the study objectives were identified. Results: Three themes and 10 sub-themes were identified. Lack of knowledge and poor adherence to EBF, perceived breastmilk insufficiency, as well as incorrect infant feeding advice given by maternal mothers and grandmothers were associated with early introduction of complementary feeding. Most participants were motivated to breastfeed due to its economic and bonding benefits, as well as seeing their infant‟s progress in growth. Challenges of breastfeeding mentioned by the participants include: lack of support from the fathers of their infants and from health care providers, breast milk leakage, and the foul smell associated with the leaking of breast milk. The participants of the study also had suggestions to help improve the support given to adolescent mothers by health care providers in PHC facilities. Conclusions and recommendations: In conclusion, this study‟s findings revealed that adolescent mothers may need extra age appropriate education and support to assist them in breastfeeding successfully at PHC facilities, the community and schools. Maternal mothers and grandmothers were found to be the primary source of a support network for most adolescent mothers as opposed to health care providers who were categorised as being the secondary source of support. Thus, breastfeeding promotion tailored at maternal mothers and grandmothers would be beneficial in improving their knowledge about the recommended infant feeding practices and consequently aid in providing appropriate support and advice to adolescent mothers. Additionally, training and attitude modification of health care providers is needed to provide adolescent mothers with age-appropriate, effective and sensitive care and counselling.

In order to attempt to develop age appropriate recommendations to assist adolescent mothers with their breastfeeding journey, the researcher undertook this research study to answer the following question: What are the breastfeeding experiences of adolescent mothers in the Nelson Mandela Bay Heath District (NMBHD)? Aim: The research aim was to determine the experiences of adolescent mothers regarding breastfeeding in NMBHD. Methods: The study implemented a qualitative research approach. To enhance the design, the researcher utilised an explorative, descriptive and contextual research design. The ethical principles that guided this study were autonomy, nonmaleficence, beneficence and justice. Fourteen adolescent mothers, attending PHC facilities in the NMBHD participated in the study. Participants were chosen from a purposive sampling technique and data were collected from semi-structured interviews, compromising of individual interviews. The researcher analysed the data using the using the eight steps of the Tesch analysis technique. Data was also analysed by an independent coder. Results obtained from the Tesch approach were compared to that of the independent coder results. Thereafter, the major themes and sub-themes that related to the study objectives were identified. Results: Three themes and 10 sub-themes were identified. Lack of knowledge and poor adherence to EBF, perceived breastmilk insufficiency, as well as incorrect infant feeding advice given by maternal mothers and grandmothers were associated with early introduction of complementary feeding. Most participants were motivated to breastfeed due to its economic and bonding benefits, as well as seeing their infant‟s progress in growth. Challenges of breastfeeding mentioned by the participants include: lack of support from the fathers of their infants and from health care providers, breast milk leakage, and the foul smell associated with the leaking of breast milk. The participants of the study also had suggestions to help improve the support given to adolescent mothers by health care providers in PHC facilities. Conclusions and recommendations: In conclusion, this study‟s findings revealed that adolescent mothers may need extra age appropriate education and support to assist them in breastfeeding successfully at PHC facilities, the community and schools. Maternal mothers and grandmothers were found to be the primary source of a support network for most adolescent mothers as opposed to health care providers who were categorised as being the secondary source of support. Thus, breastfeeding promotion tailored at maternal mothers and grandmothers would be beneficial in improving their knowledge about the recommended infant feeding practices and consequently aid in providing appropriate support and advice to adolescent mothers. Additionally, training and attitude modification of health care providers is needed to provide adolescent mothers with age-appropriate, effective and sensitive care and counselling.

- Description: Conservation agriculture (CA) has been widely recommended as one of the best ‘climate smart’ agriculture (CSA) practices in many regions of Africa and beyond. It helps to cushion smallholder farmers from the impacts of climate variability and change manifested through erratic rainfall, prolonged dry spells and droughts. CA is a preferred strategy for rehabilitating degraded agricultural land by improving its soil health for optimal crop production. However, adoption and upscaling of this farming practice in many African countries, which face critical challenges of food insecurity and soil degradation, including Malawi, is not significantly expanding despite these established benefits. This participatory action research study therefore explored factors limiting CA adoption and upscaling among the smallholder farmers in Khombedza Extension Planning Area where Total LandCare, the Malawian Ministry of Agriculture and other NGOs have been supporting farmers to adopt CA practices for more than five years. Participatory approaches were used throughout the research process for data collection, with farmers acting as co-researchers as they are best placed to identify the farming challenges and recommend solutions. Key informant interviews and field observations complemented and validated some of the results from the participatory rural appraisal (PRA) activities. The study findings revealed a number of factors behind low CA adoption and upscaling, with many relating to the poor extension system promoted by NGOs and government extension staff. Other factors relate to farmers’ perceptions and are linked to the CA system itself. The on-farm participatory training clarified the majority of farmers’ understanding and changed their mindset towards CA practices, which in turn increased its visibility in terms of adoption and scale of upscaling across the villages under study. In trying to address the poor extension system, as observed and reported by the majority of participants, the research practically tested a “Farmer Neighbourhood (FN) model”, which provided a greater opportunity for farm level interactive learning and provision of better farmer-to-farmer and farmer-to-field staff extension support. The majority of participants and field staff, as well as members of the National Conservation Agriculture Task Force (NCATF) in Malawi, made a recommendation to replicate this model of targeting and supporting farmers in order to increase CA visibility throughout the country. Participation and interactive farmer learning emerged as major themes, which guided successful implementation of the research whilst addressing the research questions and objectives.

- Description: The range and use of ecosystem services provided by urban sacred sites has hardly been considered in studies of urban ecology, sustainability and human wellbeing. This paper examines the perceived ecosystem services supplied by green spaces or gardens associated with places of religious worship and appreciated by worshippers in a mid-sized town in South Africa. A questionnaire with open, closed and Likert scale questions was administered at 30 places of worship (25 with gardens and five without). Respondents identified a wide diversity of ecosystem services provided by gardens, with social ones being more recognized than ecological, and economic services the least. Approximately two-thirds of respondents visited a sacred site garden weekly or more often. The majority of respondents (96%) felt that a garden was necessary because it added to their feelings of connection with God, or helped them relax and so be better able to concentrate, and 54% stated that a garden enhanced their overall spiritual experience. Regression analysis revealed that aesthetic appreciation of a garden was significantly related to woody plant species richness, number and basal area in the garden. On the other hand, spiritual experience was positively related to woody plant basal area, but not species richness nor tree number. Neither size of the garden, nor number of years the respondents had been vising a particular sacred site had any influence on the rated spiritual or aesthetic experiences. These results reveal the widely appreciated ecosystem services provided by urban sacred spaces and their centrality in enhancing spiritual satisfaction for some.

- Description: The purpose of this treatise is to develop a spirit of understanding affirmative action as a strategy that gives South Africa a human face of equality. The strategic development of affirmative action as part of Employment Equity Act is based on equality at workplace. This work takes note of the need to integrate human resource development for employment, productivity and education system that is based on formal education, prior knowledge education (RPL) and previous experience. The imbalances were designed to be of racial reflection therefore the redress process is racial in character but non-racial in content as the envisaged society is a non-racial society. The historical background of inequality and racial discrimination is noted in the environment of employment and on how other laws were enforcing the inequality. The arguments against affirmative action are debated and valid points of such arguments are noted as points of concern that must be considered in the process to attain equality. This work views affirmative action as a process that goes beyond employment relations and work as an instrument to change society by addressing social needs and services that have a reflection of inequality. Education is viewed as the out most important process to change the lives of people as affirmative action has a requirement of suitably qualified candidates to be affirmed. In South Africa problems of inequality were political designed but were enforced by various laws that were having material and psychological impact on the previously disadvantaged. The designated groups were divided into Africans, Indians and Coloureds, in Naidoo v Minister of Safety and Security this principle of defining designated racial groups was promoted in correction to the direction that was taken in Motala v University of Natal.Affirmative action is a legal process that addresses political designed problems. It is also a process that is exposed to abuse. Corrupt officials and managers appoint employees that do not qualify for posts on the bases of political affiliation or any other ground of discrimination. This is discussed with reference to the allegations of SADTU selling posts for principals, senior managers appointed in state co-operatives. The above mentioned tendencies are noted as part of negative indicators on the process that is meant to bring equality and non-racial society where all the citizens are given equal opportunities. This work views affirmative action as a strategy that is based on achieving a society that has a human face where race shall not be a point of reference.

- Description: The spread of contract farming in South Africa in recent years has provoked an ideological debate in literature. Linking small-scale vegetable farmers with lucrative agricultural markets through agribusiness value chains is seen as one of the foremost emerging agricultural practices to develop the subsistence farming sector into a mainstream economic sector – thereby revitalising the rural economy and alleviating poverty levels in the developing rural areas of South Africa. However, the challenges agribusiness and small-scale farmers experience in contract farming engagement and the prospects for enhancing the inclusion of small-scale farmers into modern value chains remain open to debate – two decades after transition to democracy. Yet the factors and mechanisms influencing the effective application of contract farming in the transition to commercial farming by small-scale farmers have not been thoroughly explored in South African research. Despite the efforts and the substantial investments made and the various policies and initiatives instigated to fast-track the linkages of small-scale farmers into high-value markets, the success stories of previously disadvantaged farmers operating in commercial agri-food chains are rare. Given the millions of small-scale farmers in former homelands alone, the negligible number of small-scale farmers successfully operating in commercial agri-food chains shows that the objectives to enable small-scale farmers to improve their livelihoods through participation in commercial agri-food chains have not yet been met. The broad objectives of the study were therefore to investigate the agribusiness challenges inherent in contract farming and the conditions and incentives required by agribusiness firms to engage small-scale vegetable farmers in contract farming programmes. Furthermore, the study examined the role played by the South African government to reduce the high transaction costs incurred by agribusinesses when engaging small-scale farmers in contractual arrangements. The Amathole and Sarah Baartman (formerly Cacadu) district municipalities in the Eastern Cape Province of South Africa were chosen as the composite survey area for this study. A predominantly qualitative research approach was applied to gather data on the phenomena under study. The following methodologies and research instruments and tools were selected. Firstly – as the secondary component of the research – a systematic review of literature to date was conducted to guide the empirical research and primary methodology. Secondly, the empirical component of the study comprised a questionnaire survey, unstructured interviews and focus group discussions. The questionnaire survey was used to collect data from the agribusiness firms in the area surveyed concerning the following aspects: the significant determinants of contract farming, the incentives required by the agribusiness firms to engage small-scale vegetable farmers in their contract farming programmes and the challenges faced by agribusiness firms in their interaction with small-scale farmers in contractual arrangements. Unstructured interviews were used to gather data from officials at each of the three levels of government – the Department of Rural Development and Land Reform nationally, Department of Agriculture and Land Reform provincially and (at local government level) two district municipalities – on the role played by government to reduce the high transaction costs incurred by agri-firms when procuring agricultural raw materials from small-scale vegetable farmers. Focus group discussions were conducted with small-scale farmers regarding their perspective on working with agribusiness firms and to establish the distinguishing characteristics of small-scale farmers in the area surveyed. Relevant policy documents collected from two of the three representative groups of the study population, i.e. agribusiness personnel and government officials, provided the essential context. The study revealed a limited number of contract farming business linkages between small-scale vegetable farmers and agribusiness firms in the survey area. Those that do exist are problematic to both the agribusiness firms and the small-scale farmers. It emerged that the contract farming environment in the area surveyed is highly polarised and characterised by a fundamental conflict of interest between agribusiness and farmer. Among the divergent key factors inhibiting contract farming engagement were a lack in terms of quality seeds, trust, entrepreneurial skills and formal contract agreements. Asset endowment (both land and non-land assets) was found to be significant pre-selection determinants in the farmer’s capacity to be contracted. Access to innovative technology, as well as government incentives such as production inputs, were found to be critical to agribusiness firms to engage smallscale farmers in their contract farming programmes. Government assistance in terms of high transaction costs to agribusiness firms working with large groups of small-scale farmers was found to be essential but inadequate under current policy. This impacts directly on the effectiveness and promotion of contract farming. Furthermore, the current results corroborate the findings of numerous South African studies in the vast body of worldwide research. Firstly, lack of land and non-land assets continue to be major impediments to the direct participa-tion of small-scale farmers in contract farming programmes and, secondly, the transaction and market information costs incurred by agribusiness prevent the participation of less endowed farmers in contract farming programmes. Conducted within the interpretivist paradigm, the explorative research identified wide-ranging challenges in the relationship between agri-business and small-scale farmers which directly impact the effective-ness of contract farming as a development and agrarian reform strategy. Despite their problematic relationship, however, agribusiness and small-scale contract farmers were in agreement that the government needs to expand its support for agri-firms to incentivise greater numbers of small-scale farmers having the opportunity to achieve commercial status through contract farming. The study therefore recommends a collaborative partnership between private firms and government, with state support through revised policies and development programmes. These amendments are crucial to enhancing the engagement of small-scale vegetable farmers in lucrative agri-food chains.

The study goes further to understand the role that could be played by University of Fort Hare and Buffalo City Metropolitan Municipality in capacitating small scale urban farmers in the city of East London. Unemployment and food insecurity are the key challenges that are affecting many families in South Africa, including urban dwellers. The main objective of this study therefore is to investigate the contributions of urban farming in securing food security and livelihoods in East London. This study adopted a mixed methods research approach, where both quantitative and qualitative methods were used to harvest data. Statistical analysis (descriptive) was then used to analyse quantitative data. Thematic approach used to analyse qualitative data. The study shows that urban farming plays an important role in the livelihoods of urban dwellers. However, the sector still faces various challenges such as lack of recognition by authorities. The study also revealed that the city of East London has potential to establish agricultural urbanism as it has most of the essential aspects that are necessary to establish it. The study recommends strengthening of the partnership between University of Fort Hare, Buffalo City Metropolitan Municipality and small scale urban farmers in East London.

- Description: This thesis examines the nature of governance in the Zimbabwean tobacco value chain and what upgrading implications this has for participants at the lower end of the value chain, with a particular focus on smallholder tobacco growers. The nature of governance and upgrading opportunities will provide further implications for broader economic development in Zimbabwe. Value chain analysis was the over-arching method, adopting a mixed methods approach of both quantitative and qualitative data analysis. Data attained from the Tobacco and Industry Marketing Board (TIMB) was used to construct a Zimbabwean tobacco profile. This information was used to construct a simple Global Value Chain (GVC) framework in order to obtain an understanding of the Zimbabwean tobacco value chain. Information was gathered at the top end of the value chain via documents and data from British American Tobacco (BAT) and information was gathered at the middle and lower end of the value chain through interviews. It was found that the Zimbabwean tobacco value chain is characterised by two types of governance: modular and hierarchy. Modular governance existed where the value chain was disjointed by the leaf merchant and hierarchy governance existed where cigarette manufacturers have vertically integrated themselves backwards into the tobacco growing segment. It was found that contract lines offer smallholder tobacco growers’ financial and technical support that would otherwise be difficult to attain. This increased the likelihood for smallholder tobacco growers to produce a high quality crop that met Good Agricultural Practices (GAP) and other compliancy requirements; therefore achieving product and process upgrading. However, the environmental impact of tobacco growing through deforestation and the possibility of lead cigarette manufacturers relocating their operations to a different geographical location (as is the nature of GVCs) threatens the sustainability of Zimbabwe’s tobacco industry. Despite these issues it was argued that the tobacco value chain could assist Zimbabwe’s economy in diversifying away from simple tobacco production towards valueadding tobacco sectors, such as processing, by-product processing and cigarette manufacturing.

- Description: This thesis examines the nature of governance in the Zimbabwean tobacco value chain and what upgrading implications this has for participants at the lower end of the value chain, with a particular focus on smallholder tobacco growers. The nature of governance and upgrading opportunities will provide further implications for broader economic development in Zimbabwe. Value chain analysis was the over-arching method, adopting a mixed methods approach of both quantitative and qualitative data analysis. Data attained from the Tobacco and Industry Marketing Board (TIMB) was used to construct a Zimbabwean tobacco profile. This information was used to construct a simple Global Value Chain (GVC) framework in order to obtain an understanding of the Zimbabwean tobacco value chain. Information was gathered at the top end of the value chain via documents and data from British American Tobacco (BAT) and information was gathered at the middle and lower end of the value chain through interviews. It was found that the Zimbabwean tobacco value chain is characterised by two types of governance: modular and hierarchy. Modular governance existed where the value chain was disjointed by the leaf merchant and hierarchy governance existed where cigarette manufacturers have vertically integrated themselves backwards into the tobacco growing segment. It was found that contract lines offer smallholder tobacco growers’ financial and technical support that would otherwise be difficult to attain. This increased the likelihood for smallholder tobacco growers to produce a high quality crop that met Good Agricultural Practices (GAP) and other compliancy requirements; therefore achieving product and process upgrading. However, the environmental impact of tobacco growing through deforestation and the possibility of lead cigarette manufacturers relocating their operations to a different geographical location (as is the nature of GVCs) threatens the sustainability of Zimbabwe’s tobacco industry.

- Description: The aim of the study was to investigate agriculture educational programme and the promotion of job creation skills in the OFS FET College. The interpretivism paradigm and design approach were adopted in this qualitative research. The sample consisted of three final year students, three facilitators and one coordinator. The non-probability and purposive sampling techniques was used for the qualitative research. The qualitative data was descriptive, and thematically analysed. The study found that there is a big demand for agricultural professional in South Africa but very few are choosing this career. The quality of education in agricultural sector is not where it should be. The demand for skilled people in the sector is growing, while the number of students enrolling in agriculture-related training continues to decrease. Africa’s agricultural education is failing to produce a new wave of farmers. The study found that FET colleges did not train and provide enough skills to students to enhance development in agriculture sectors and therefore make students non-productive at labour market. The study also found that the FET colleges had left a trail of low skills, partially educated and jobless youth behind. The study also found that the curriculum tended to be outmoded, irrelevant to adequately address the challenges facing modern agriculture .The curriculum still focused on farm production rather than encompassing all segments of agricultural value chains, entrepreneurship, and agriculture business processing market. Agriculture forms the basic food security of every country .It contributes a large proportion of gross domestic product in many developing countries and is the source of income and subsistence for many of the poorest and most vulnerable individuals and households.

- Description: Revenue Management (RM) in the airline industry is the practise of selling fixed capacity as a service over a finite time horizon. The market is characterised by the customers’ willingness to pay different prices for the service. This creates the opportunity to target different customer segments and use price differential to attain the optimal passenger fare mix to maximise revenue. The aim is to maximise revenue and an airline can expect revenue increase of between 3 to 7 percent with the successful implementation of a Revenue Management system. The question of whether the revenue increase can be attributed to the RMS is crucial in determining its level of success and validating the optimisation strategy applied (Rannou and Melli, 2003). South African Airways (SAA) migration from Leg-based optimisation to Origin-Destination (O&D) network based revenue management optimisation created the opportunity for this study to measure and evaluate the RMS performance. Revenue performance measuring tools using inventory systems data to measure RMS performance, ASK (Available Seat Kilometre), RASK (Revenue per Available Seat Kilometre), CASK (Cost per Available Seat Kilometre), RPK (Revenue Passenger Kilometre) and cabin factor yield. The limitations relating to the performance measuring tools utilising inventory system data, is the inability for continuous measurement and the isolation of the impact to revenue due to the RMS on its own. In seeking to gauge the performance of the O&D optimisation, the Revenue Opportunity Model (ROM) is applied. ROM is a post departure measuring tool utilised to continuously measure and isolate the contribution of the RMS on SAA’s O&D network. The revenue opportunity achieved versus the potential revenue was assessed. A revenue comparison of the airlines 2014 and 2015 financial year is performed. The results of the analysis showed the O&D optimisation yielded positive revenue capture on routes that applied the correct optimisation strategy. Recommendations on the optimisation strategy to be applied on routes having average or low revenues captured are presented. The aim is to provide the SAA revenue management department with tangible solutions that would result in increased revenue for the SAA network.

- Description: Alex Baine is a contemporary Ugandan woman artist who graduated from the Margaret Trowell School of Industrial and Fine Art (or MTSIFA) in 1989. During her final year, she painted a large work, Women's Emancipation in Uganda (Fig. 1) (1989), in which she represented women in domestic and nondomestic (conventional and unconventional) economies, spaces, and histories. Baine has not produced any other painting since her graduation. It is evident that Baine's art career, like those of several other female graduates of the Art School, has been interrupted by many issues including family, business, further education, and diversion into other professions. However, in this article I acknowledge that she championed women's emancipation in Uganda's contemporary art in the 1980s, a debate that I trace in her work.

- Description: Central to Hsp90’s biological function is its ability to interconvert between various conformational states. Drug targeting of Hsp90’s regulatory mechanisms, including its modulation by co-chaperone association, presents as an attractive therapeutic strategy for Hsp90 associated pathologies. Here, we utilize homology modeling techniques to calculate full-length structures of human Hsp90α in closed and partially-open conformations. Atomistic simulations of these structures demonstrated that bound ATP stabilizes the dimer by ‘tensing’ each protomer, while ADP and apo configurations ‘relax’ the complex by increasing global flexibility. Dynamic residue network analysis revealed regions of the protein involved in intra-protein communication, and identified several overlapping key communication hubs that correlate with known functional sites. Perturbation response scanning analysis identified several potential residue sites capable of modulating conformational change in favour of interstate conversion. For the ATP-bound open conformation, these sites were found to overlap with known Aha1 and client binding sites, demonstrating how naturally occurring forces associated with co-factor binding could allosterically modulate conformational dynamics.

- Description: The success of a course offered by a university and the effectiveness of the instructors have commonly been measured by means of student evaluations. The feedback generated is typically used to identify instructors who need additional training, courses that need to be restructured or the need for financial rewards for those who excel. The principal objective of educating students is, knowledge, training and skills they can use and apply after graduating, regardless of the field of study. The perception of the Alumni about the extent of learning and the usefulness of the knowledge is a key measure for universities to assess their success. A service guarantee is defined as a formal promise made to customers about the service they will receive or it is a written promise made by the company through advertising or company literature that it will provide compensation if promises are broken. In order to ensure customer satisfaction in a service offering, the quality of service performance needs to be guaranteed. Many service industries promise a level of service performance, with or without conditions attached. Customer value is a complex concept as it is often interpreted with various meanings depending on the point of view adopted. A definition of customer value is the perceived value that the customer gains when purchasing a product or receiving a service. However, customer value can be used in a variety of contexts. The purpose of this research study is to measure the perception and satisfaction of Alumni of the Department of Computing Sciences and identify areas for improvement by performing a systematic analysis of the determinants of satisfaction. This research is an exploratory, quantitative study consisting of literature- and case-study components used to test proposed hypotheses. The literature study was performed on secondary sources to establish the key concepts related to the topics of Service Guarantee and Marketing, Stakeholder Theory, Customer-perceived Value and Alumni Perceptions. The empirical study consisted of surveys (questionnaires) completed by Alumni of the Department of Computing Sciences. The questionnaire used in this research consisted of questions regarding demographic data and questions regarding perceived perception of the Department of Computing Sciences and influencing factors. Descriptive statistics were used to summarise the data into a more compact form which could simplify the identification of patterns in the data. Inferential statistics were used to verify if conclusions made from the sample data could be inferred onto a larger population. Recommended university and teaching practices based on the statistical analysis of the survey results were identified. A model identified the following factors as having an influence on Alumni Satisfaction with the NMMU Department of Computing Sciences: Customer Satisfaction, Course Contents, Modern Technologies, Academic Staff, Admin. Staff, Departments, University Atmosphere and Perceived Value. The importance of each factor was identified to understand how to improve the Alumni perception. According to the inferential ranking of Alumni Satisfaction that ranks the factors on the average mean values, a factor that should be improved upon is the Alumni Network. Recommended improvements were suggested for the Department of Computing Sciences based on the statistical analysis of the survey results. Two sub-groups were defined by different levels of education and they were found to have different perceptions of the factors that were measured. It was shown that there are small and medium significant differences in only two of the factors of the proposed Alumni satisfaction model, distinguising through different levels of education. The Alumni Satisfaction model developed in this study specified the factors that influence Alumni Satisfaction with the Deptarment of Computing Sciences and the effect that each of these factors has on that satisfaction.

- Description: Against the background of a re-emphasis of human rights, social justice and democracy, learner leadership has become a topic of interest and importance. An absence of any meaningful form of leadership development among learners in formerly disadvantaged schools in South Africa prompted this interest into exploring the development of learner leadership. A more recent approach to learner leadership in many countries, including South Africa, has been to look at providing the necessary platform for learners to experience a more shared, cooperative, transformative and service approach within schools in order for them to develop their capacity to lead. This is supported by theoretical developments in the field of leadership, such as Distributive Leadership and Servant Leadership, which emphasise shared leadership. These developments were based on dialogue and strong relationships, where learner leaders situated their practices in moral action, with signs of individual growth, social justice and democratic positioning. In spite of this, not much is known of learner leadership development in South Africa. There are very few studies, none using approaches which look at the context and situation holistically. Hence this study, using Cultural Historical Activity Theory and Critical Realism as under-labourer, for its stance on ontological, epistemological and principled expectations of reality and its understandings on agency and structure, is advanced. Transformational leadership theories, in particular Distributive and Servant Leadership, are used as lenses to help make sense of the nature of learner leaders’ practice and the development of leadership. The aim of the single case study was to discover and explore how and under what circumstances learner leadership could be developed. To this end the researcher established a leadership development group at a previously disadvantaged secondary school. This project provided the platform for leadership development initiatives and became the activity which is the focus of this research. The study examines how leadership is learned and practised, and how the participants interrelate and influence learning and practice in their activity system. It examines the challenges that the learner leaders faced within their communities and what the underlying causes of these challenges were. Qualitative semi-structured interviews, document analysis, direct observation and focus groups were used to collect data. Non-probability sampling, in particular purposive sampling, was used in selecting the sixteen learner leader volunteers who participated in the study. These learners represented various ages, gender and leadership positions that were held in the school. Using inductive, abductive and retroductive modes of inference, the data was abstracted and analysed. The Change Laboratory workshop was used to boost the growth of shared collective views of the learner leaders within the changing object and activity system, in order to build and develop new practices, tools and models. The study recognized that learner leadership was generated by numerous mechanisms, which included the need to overcome the calamitous scarcity of virtuous leadership within their communities; the need to address cultural and historical assumptions, prejudices, and values that existed which reinforced their existing perceptions and behaviour towards leadership; the need to create a space for learner leaders to share responsibilities, thoughts, and become reciprocally dependent on each other, developing together due to their cooperative efforts; the need to demonstrate a willingness and the necessary resilience to survive in an environment whose socioeconomic demands and effects are restrictive and disempowering; a need to respond to the demand for impartiality and access to leadership; and a need to know that one is able to transform the practice of leadership, without it necessarily affecting one’s culture, in such a way that the needs of the people are met. This thesis reports on encouraging signs of leadership growth within the activity, observed and documented over a period of three years. The intervention led to behaviour and attitudinal development that suggests transformative learning and agency. The study’s findings further clarify the many challenges the potential learner leaders faced. Chief among these was the lack of adequate and efficient structures and systems in their communities in order for effective leadership to be established and practised in their communities. These included weak social structures in homes that were unable to support and meet the needs of the learner leaders due to the breakdown of families. Negative forces included high levels of authoritarian leadership practised by a restrictive socialised patriarchy. The underlying causes of these challenges include the perceived threat to individual dignity and survival; the fear of change; the feeling of powerlessness; a lack of hope which fuelled an apathy, a low self-esteem and poor attitude to education; adverse socioeconomic conditions; poor communication skills; a lack of adult role models and willpower; the demand for impartiality and access to leadership knowledge. In order to encourage learner leaders to advance their practice of leadership, the study recommends that adolescents be made to feel valued and included in the development process of leadership so that their willingness to engage with the process becomes pre-emptive. Learner leaders prefer structure, so it becomes all the more important to ensure that any rules, policies and guidelines that are established exhibit a demonstration of transparency and accountability. The study also recommends that when developing an understanding of the learner leaders’ behaviour, using their socio-cultural and historical contexts, they are provided with a non-threatening platform. This enables them to become empowered to actively participate, debate and dialogue collaboratively. They have an opportunity to demonstrate a willingness to engage with each other over tensions that arise, breaking the bonds of socialized pathology.

Non-probability sampling, in particular purposive sampling, was used in selecting the sixteen learner leader volunteers who participated in the study. These learners represented various ages, gender and leadership positions that were held in the school. Using inductive, abductive and retroductive modes of inference, the data was abstracted and analysed. The Change Laboratory workshop was used to boost the growth of shared collective views of the learner leaders within the changing object and activity system, in order to build and develop new practices, tools and models. The study recognized that learner leadership was generated by numerous mechanisms, which included the need to overcome the calamitous scarcity of virtuous leadership within their communities; the need to address cultural and historical assumptions, prejudices, and values that existed which reinforced their existing perceptions and behaviour towards leadership; the need to create a space for learner leaders to share responsibilities, thoughts, and become reciprocally dependent on each other, developing together due to their cooperative efforts; the need to demonstrate a willingness and the necessary resilience to survive in an environment whose socioeconomic demands and effects are restrictive and disempowering; a need to respond to the demand for impartiality and access to leadership; and a need to know that one is able to transform the practice of leadership, without it necessarily affecting one’s culture, in such a way that the needs of the people are met. This thesis reports on encouraging signs of leadership growth within the activity, observed and documented over a period of three years. The intervention led to behaviour and attitudinal development that suggests transformative learning and agency. The study’s findings further clarify the many challenges the potential learner leaders faced. Chief among these was the lack of adequate and efficient structures and systems in their communities in order for effective leadership to be established and practised in their communities. These included weak social structures in homes that were unable to support and meet the needs of the learner leaders due to the breakdown of families. Negative forces included high levels of authoritarian leadership practised by a restrictive socialised patriarchy. The underlying causes of these challenges include the perceived threat to individual dignity and survival; the fear of change; the feeling of powerlessness; a lack of hope which fuelled an apathy, a low self-esteem and poor attitude to education; adverse socioeconomic conditions; poor communication skills; a lack of adult role models and willpower; the demand for impartiality and access to leadership knowledge. In order to encourage learner leaders to advance their practice of leadership, the study recommends that adolescents be made to feel valued and included in the development process of leadership so that their willingness to engage with the process becomes pre-emptive. Learner leaders prefer structure, so it becomes all the more important to ensure that any rules, policies and guidelines that are established exhibit a demonstration of transparency and accountability. The study also recommends that when developing an understanding of the learner leaders’ behaviour, using their socio-cultural and historical contexts, they are provided with a non-threatening platform. This enables them to become empowered to actively participate, debate and dialogue collaboratively. They have an opportunity to demonstrate a willingness to engage with each other over tensions that arise, breaking the bonds of socialized pathology.
