- Description: According to Pienaar and Raymond (2013, p.10) learners with disabilities have historically experienced the most serious exclusion from learning. The worldwide call for inclusive education prompted South Africa to develop the White Paper 6 (WP6) (2001, p.18) which clearly states that for Inclusive Education to be successfully implemented in South Africa, there has to be an acknowledgement that all children and youth can learn. The implementation of WP6 therefore not only benefits learners with special educational needs, but all South African learners by implementing "a more flexible system of education that focuses on removing barriers to learning and creating learning-friendly environments" (Pienaar and Raymond, 2013, pp. 10-11). However, a great disparity exists in what is proposed in official documents such as WP6 and what parents of children with barriers to learning actually experience within schools. This phenomenological study employed memory work, drawings and focus group discussions with four purposively selected parents to explore parents’ experiences of the education of their children who are on the Autistic Spectrum. Bronfenbrenner’s Eco-systemic perspective was used to make meaning of the data. The findings show that parents find the education of their autistic children as a stressful and isolating experience because of an unprepared education system. Despite the challenges, the participants also find their experiences to be a journey of personal growth and fulfilment. The study therefore recommends that schools should engage parents of autistic children more actively in order to make inclusion of such children effective. Teachers who are expected to practice inclusivity in schools should be adequately prepared to work with children presenting with ASD through a collaborative effort of the Department of Health and the Department of Education.

- Description: This treatise is founded in a belief that urban ecosystems should not be separate from natural ones and seeks to find ways in which existing urban systems can be reintegrated. This reintegration will be two-fold, providing a remedy for ecologically destructive urban systems as well as providing an opportunity to develop a holistic and sustainable alternative to current practices that generate waste and pollution. The treatise will focus on the management of polluted storm water, specifically along the Walmer catchment area which flows east into Airport Valley and Shark River Valley, and ways in which horticulture building systems can be utilised to achieve remedial action naturally, producing vast amounts of nutritious food for the surrounding community in the process. Impetus for this topic grew out of a concern that the author has for the current state of sustainable practices within South Africa, specifically regarding the relationship between water and agriculture (food). 60 – 70% of South Africa’s water demand is agricultural, with poor water management infrastructure and the current drought severely affecting the agricultural output (food supply) of the country. The increased demand puts immense pressure on South African farmers who have dwindling arable land and less water with which to cultivate crops. South Africa’s population is two thirds urbanised, meaning that most of the population lives in urban centres around the country. This treatise proposes that water-wise urban agricultural systems could be utilised to further cement food and water security in an urban setting by supplementing the food supply chain with local, city-grown produce. The research conducted will generate an architectural and urban intervention that marries the natural with the built environment in a strategically and intentionally designed relationship that exploits synergies between these two environments.

- Description: This treatise is preoccupied with the design of an Indigenous Medicine Research Institute within the region of (the former) underdeveloped Transkei. The interest in the matter developed out of a concern for a medical system which finds itself in jeopardy of depletion due to over-harvesting which is endangering the ecosystem and its dependents. This is as a resultant lack of development due to its informal nature, and loss of impact of traditional knowledge. Indigenous medicine forms part of the cultural, religious, medical and socio-economical back bone of the region, research will create opportunities for the discovery of new medicinal plants and exploring the applications of age-old remedies in contemporary times. Thus developing and promoting indigenous medicine of the region to a wider user group, in a sustainable method which will protect the environment. Architecturally, the design seeks to respond to an in-depth quest to identify the appropriate nurturing of the relationship between learning and the natural environment, while accommodating the necessary programmatic components which will satisfy the needs of the Institute; namely education, conservation and research. Central to the design is the development of an architecture that addresses the fundamental challenges of education, conservation and the research of plants, in a manner that provides opportunities for collaborative learning practices and an interchange between the user-groups and the plants to be studied, resulting in a building that is at harmony with nature. Through this collaboration of the diverse components, an effective scheme has evolved which offers a singular co-operative environment for the indigenous medical system, in a particular effort to transform the learning environment and extend of the knowledge, as a catalyst for further development and reconciliation with nature. Set in the academic context of the Walter Sisulu University Campus, a once major university in Transkei renowned for its medical department, the Research Institute facility re-establishes the University's medical status in a manner that truly represents its region. The built form will integrate itself into the existing campus conditions in a contemporary way that sets up a response which is conducive to the discovery, preservation and sharing of knowledge pertaining to indigenous medicine.

- Description: This thesis examines the impact of the recapitalisation and development programme on cattle producing farmers in Joe Gqabi and Chris Hani Districts. This research is based on the insight that most of the Eastern Cape cattle producing farmers are facing financial problems and their farms are dilapidated even though there are interventions from the Department of Rural Development and Agrarian Reform and Rural Development and Land Reform through programmes such as CASP and RADP for rescuing the cattle producing farmers. The major challenges faced by the cattle producing farmers into getting the funding will be established in this study. The main focus is on the farms that have already got the funding and also on the ones that are still in the pipeline for being funded by the Department of Rural Development and Land Reform. To a lesser extent, the thesis draws on findings from careful considerations of case studies comprising ten farms, thus five farms from Joe Gqabi and five from Chris Hani Districts. The research methods under this research design yielded data that was descriptive and exploratory based on human experiences and are associated with discovering changes in situations. The research findings show that delays in releasing recapitalisation and development funds for land reform beneficiaries have been recognised as one of the main reasons for the collapse of land reform projects. In most cases the funds are arriving long after they were needed for important faming activities. The delays are also leading to permanent closure of the farms. Therefore, it is essential for the success of land reform programmes to ensure that the production model is designed so as to generate benefits for land reform beneficiaries. This thesis is concluded by making recommendations to the Department of Rural Development and Land Reform in order to address the identified Recapitalisation and Development Funding challenges as well as to identify what can be considered as effective financial support to the land reform projects.

- Description: Despite the decreasing contribution of agriculture to Gross Domestic Product (GDP) in South Africa, agricultural activities are critical in the development of rural households. These activities are an important route through which these rural communities can reduce poverty. This is mainly because agriculture has been the main source of income and employment in rural areas in South Africa and other less developed countries (LDC). However, it has not generated sufficient income to sustain rural households. Rural areas are characterised by factors such as low socio-economic conditions, low standards of living, lack of access to markets and inadequate infrastructure that does not create an enabling environment for private sector involvement. The private sector is not actively involved or engaged in rural development. Rural development involves improvement in the economic security of people in rural areas. It is poor households that look for employment in agriculture. The poor are portrayed in terms of qualifications, employment, access to resources, basic health services, skills possessed, self- sustaining activities, and income and expenditure patterns. Many individuals in rural areas are pushed into non-agricultural activities due to lack of opportunities in agricultural activities. Lack of opportunities in agriculture can be caused by subsistence agriculture in small holdings of land and lack of appropriate skills sets for certain agricultural activities. Ultimately, it is poor individuals who increase their dependence on agriculture. The primary objective of this research was to obtain a better understanding of the contribution of agriculture in rural development in the Mbhashe Local Municipality (MLM). Furthermore, the necessary conditions required to sustain livelihoods in the rural areas were identified. This was mainly done in an attempt to improve the quality of life in the rural areas. The study was based on three objectives. The first objective was to identify the constraints to agricultural activities in the Mbashe Local Municipality; the second was to investigate the plight of rural people in the Mbhashe Local Municipality. Lastly, the third objective was to investigate the contribution of agriculture in rural development in the study area. The main finding with regards to the first objective is that facors such as lack of infrastructure, low socio-economic conditions, lack of appropriate skills and lack of opportunities in agriculture are some of the constraints to agricultural activities. Investments in basic infrastructure need to be significant so that funds can flow into the rural areas to be invested in livelihood activities in order to create more employment opportunities. With regard to the second objective, the main finding is that rural people need to be empowered through increased knowledge and skills. This involves improving literacy and skills training, because the outcome of this training is that they are able to stand on their own feet and provide for their families. The main finding with regard to the third objective is that rural areas, by nature, are not easy to service but have indigenous knowledge that can be used in agriculture. However, the government must support them with the necessary infrastructure. Agriculture has been a major source of income and employment in the Mbashe Municipality.

- Description: This research developed two novel distributed algorithms inspired by Ant Colony Optimisation (ACO) for a solution to the problem of dynamic Routing and Wavelength Assignment (RWA) with wavelength continuity constraint in Optical Burst Switching (OBS) networks utilising both the traditional International Telecommunication Union (ITU) Fixed Grid Wavelength Division Multiplexing (WDM) and Flexible Spectrum scenarios. The growing demand for more bandwidth in optical networks require more efficient utilisation of available optical resources. OBS is a promising optical switching technique for the improved utilisation of optical network resources over the current optical circuit switching technique. The development of newer technologies has introduced higher rate transmissions and various modulation formats, however, introducing these technologies into the traditional ITU Fixed Grid does not efficiently utilise the available bandwidth. Flexible Spectrum is a promising approach offering a solution to the problem of improving bandwidth utilisation, which comes with a potential cost. Transmissions have the potential for impairment with respect to the increased traffic and lack of large channel spacing. Proposed routing algorithms should be aware of the linear and non-linear Physical Layer Impairments (PLIs) in order to operate closer to optimum performance. The OBS resource reservation protocol does not cater for the loss of transmissions, Burst Control Packets (BCPs) included, due to physical layer impairments. The protocol was adapted for use in Flexible Spectrum. Investigation of the use of a route and wavelength combination, from source to destination node pair, for the RWA process was proposed for ACO-based approaches to enforce the establishment and use of complete paths for greedy exploitation in Flexible Spectrum was conducted. The routing tuple for the RWA process is the tight coupling of a route and wavelength in combination intended to promote the greedy exploitation of successful paths for transmission requests. The application of the routing tuples differs from traditional ACO-based approaches and prompted the investigation of new pheromone calculation equations. The two novel proposed approaches were tested and experiments conducted comparing with and against existing algorithms (a simple greedy and an ACO-based algorithm) in a traditional ITU Fixed Grid and Flexible Spectrum scenario on three different network topologies. The proposed Flexible Spectrum Ant Colony (FSAC) approach had a markably improved performance over the existing algorithms in the ITU Fixed Grid WDM and Flexible Spectrum scenarios, while Upper Confidence Bound Routing and Wavelength Assignment (UCBRWA) algorithm was able to perform well in the traditional ITU Fixed Grid WDM scenario, but underperformed in the Flexible Spectrum scenario. The results show that the distributed ACO-based FSAC algorithm significantly improved the burst transmission success probability, providing a good solution in the Flexible Spectrum network environment undergoing transmission impairments.

- Description: Lean manufacturing has become an integral part of the global automotive industry where manufacturers strive to improve quality, reduce costs while providing customers with more variety. Organisations are implementing the Lean Production System (LPS) as a process improvement methodology to deliver their products faster, better quality and at a lower cost (Laureani & Antony, 2012). This is accomplished through the elimination of waste and continuous improvement (Kaizen). Through the effective implementation of lean principles, an organisation can realise cost competitiveness, process improvement and ultimately gain a competitive advantage. Although the theory of lean manufacturing is based on the implementation of tools, techniques and operational methods, many organisations that have implemented Lean have not reaped its full benefit. Thus, the realisation that lean manufacturing must consist of more than the summation of its operational based principles, tools and techniques. It has to be approached as a philosophy, which encompasses the entire organisation (Womack & Jones, 1996). Lean is a way of thinking and not merely the implementation of thoughts (Bhasin & Burcher, 2006). Laureani & Antony (2012) added that the fundamentals behind Lean are continuous improvement, waste elimination and employee empowerment. Lean introduction is more than the redesign of processes; the most important change must be in the knowledge of the employees (Dombrowski, Mielke & Engel, 2012). The literature clearly states that the successful implementation of a lean production system depends on more than the application of lean tools and techniques. Many authors and researchers hint that another critical factor associated with its implementation is the human aspect of the organisation. Hence, this study will examine the human related Key Success Factors (KSF‟s) required for the successful implementation of a lean system.

- Description: The South African automotive industry has experienced significant growth since its first inception in 1995. South Africa’s trade relations with other countries has facilitated the growth of this sector. Government introduced programmes that encouraged growth in the sector, namely the Motor Industry Development Programme (MIDP) and the Automotive Production and Development Programme (APDP). South Africa as the catalyst for development in Africa needs to continuously strive to integrate with other developed countries to and promote Foreign Direct Investments into the continent. The development of the industry requires organic growth to ensure that it remains sustainable. The research problem addressed in this study is to establish the role government plays in ensuring a sustained growth of Foreign Direct Investment (FDI) in the automotive sector. The establishment of this statement is imperative to the growth of automotive investments by multinationals in South Africa. Original Equipment Manufacturers (OEM) are positioned in three of the country’s eleven provinces. The Eastern Cape region has been known to be the automotive-hub of South Africa with a GDP that is driven by the secondary automotive sector consisting of multinational OEM giants such as Volkswagen South Africa (VWSA), General Motors South Africa (GMSA), Ford Motor Company, FAW and Daimler. South African OEMs are required to lobby at the principal companies before a new model can be built in the country. Lobbying involves offering competitive logistics costs to build models in South Africa. Stakeholders led by government are required to actively participate in these negotiations to sustain the industry in the country. One of the ways this can be achieved is through formulation, integration and alignment of strategies between all stakeholders. Stakeholders involve private sector and public sector working together. South Africa has achieved an open-country perception to foreign investors through the APDP. The problem statement was accurately explained and expressed clearly and sub-problems were identified from areas in the main problem that required further analysis. Literature has revealed that South African ports are considered to be the most expensive in the world and that there is a lack of port and rail integrated infrastructure. Providing a complete supply chain for logistics will result in increased FDI for South Africa. The governmental entities’ support will allow the OEMs an opportunity to increase investment in South Africa thus creating employment and adding value to the GDP of South Africa. The South African component manufacturer’s sector has grown intensively creating sustainable jobs for South Africans. The industry is structured in such a way that there is a multiplier-effect reaction to macro-economic conditions. A comprehensive literature review was executed to understand the nature and extent of the global automotive industry, the South African automotive industry, the regions that host OEMs, the Motor Industry Development Programme and the Automotive Production and Development Programme. A primary research instrument was constructed, in the form of a questionnaire, to test themes which were highlighted in the literature review which can influence the sector’s competitive advantage. A questionnaire was distributed with the assistance of industry representatives in the Transport and Logistics sector. There was consensus on many issues regarding the current structure of the South African automotive industry. Specifically, the importance of rail, efficiencies, prices and value-added services needed in the industry to attract FDIs as well as the readiness of the Port of Port Elizabeth with regards to being positioned as an automotive-hub for Sub-Saharan Africa.

- Description: The South African automotive industry has experienced significant growth since its first inception in 1995. South Africa’s trade relations with other countries has facilitated the growth of this sector. Government introduced programmes that encouraged growth in the sector, namely the Motor Industry Development Programme (MIDP) and the Automotive Production and Development Programme (APDP). South Africa as the catalyst for development in Africa needs to continuously strive to integrate with other developed countries to and promote Foreign Direct Investments into the continent. The development of the industry requires organic growth to ensure that it remains sustainable. The research problem addressed in this study is to establish the role government plays in ensuring a sustained growth of Foreign Direct Investment (FDI) in the automotive sector.

- Description: Managing a sustainable service business rests on two critical customer perceptions: Firstly, the perceived sufficiency of the value of the service, and secondly the level of value differentiation between the current service provider other service providers in the market. (DeSarbo, Ebbs, Fong & Snow, 2010; Parasuraman & Grewal, 2000) The direction for this study was prompted by the limited research available around service quality for Supply Logistics within the global automotive industry. The study identified the key factors that logistics service providers need to focus on when aligning their perceptions of service quality to that of their customers. The service gaps between customer and service provider perceptions are uncovered. Particular focus was given to: The definition gaps in service quality, The perceived level of service quality, and The size of service quality differentiation between service providers. The key finding of the study is that service differentiation is influenced by the ability of the Logistics Service Provider (LSP) to deliver a quality of service in line with the level of importance the various elements hold to the customer. The causal relationships offered a step wise understanding of improving the perceptions of customers. This perception forming process is outlined as follows: Firstly, create a common understanding of the definition of service quality and establish the comparative importance of the various elements. Having an understanding of how customers’ value service quality is a critical first step in delivering superior service. A proposed Service Quality Framework for multi-national Supply Logistics providers in the South African automotive industry Secondly, align efforts to achieve in accordance to the level of importance of the service elements. If this is achieved, LSP’s will retain positive differentiation to its competitors irrespective of the actions of those competitors. Lastly, LSP’s need to regularly review if their own perception of the service level (per element) is in line with that of the customer. The study created a service quality framework of 22 different service elements grouped in four service factors. The relative importance of these elements were uncovered. This offered insight for organizing the business around key service elements. Within Supply Logistics the operational-management-tools, engineering-skills, processes-stability and management-structure are typical elements around which customers form their perceptions. The quality of the direct staff holds the key to sustained customer satisfaction, much more so than the commercial arrangements, industry innovations and the prestige of the brand behind the service. This study laid a foundation from which future research can deeper explore the unique slant that geographical, organisational designation or customer brand lines hold on the service quality perception.

- Description: Research has shown that Attention Deficit Hyperactivity Disorder (ADHD) is one of the commonest neurodevelopmental disorders which has a negative impact on a child. However, to date limited research has been conducted on learners, and specifically those learners with ADHD, within a National Education stream. Furthermore, running concurrently with this are new developments in education in South Africa. An inclusive educational policy favours the incorporation of all children into a mainstream scholastic setting, regardless of their diverse needs. In addition to educational changes for children with ADHD, many parents are presently unable to afford the medication commonly used to treat the disorder, resulting in both parents and teachers having to manage these children with limited professional support. It is widely accepted that early assessment and intervention are necessary in order to maximise a child’s potential. For this reason, the primary aim of this study was to explore and describe the developmental profile of children with ADHD on the Griffiths Mental Development Scales-Extended Revised (GMDS-ER). Further aims were to compare the performance of the clinical sample to a normal South African sample. In order to achieve these aims, a quantitative, exploratory-descriptive research design was employed. The sample (N = 38) of ADHD were selected by means of a non-probability, purposive sampling procedure, from various pre-school and primary schools in the Nelson Mandela Metropole. The normal sample (N = 38) was drawn from an existing database created during the revision of the Scales. Information was collated using the Conners 39 Item Teacher Rating Scale, biographical data, as well as the results of an assessment from the GMDS-ER. In this study the general performance of the ADHD sample on the GMDS-ER was found to be above average. Furthermore the performance of these children on the six Subscales of the GMDS-ER ranged from average to superior, with the poorest performance being on the Eye and Hand Co-ordination Subscale, and the best performance being on the Performance Subscale. Significant differences between the ADHD and normal sample were found on the General Quotient (GQ) as well as three of the six Subscales, namely, the Hearing and Speech, Eye and Hand Co-ordination and Performance Subscales. Generally, the results of the study suggest that a specific developmental profile for children with ADHD exists. Additionally, the study highlighted the success with which the GMDS-ER can be utilised on a specific clinical population.

- Description: There is widespread international interest in Attention Deficit Hyperactivity Disorder (ADHD). ADHD was considered to be a childhood onset neurodevelopmental disorder with few presenting symptoms in adulthood. Current research disputes this belief and there are a significant number of adults that meet the diagnostic criteria for ADHD in adulthood. This study explored the experience of selected Psychiatrists and Psychologists providing mental health services to adults living with ADHD. The awareness and presenting patterns of ADHD among adults as well as the intervention strategies used by these practitioners was explored. Furthermore, an exploration of the differential diagnoses associated with ADHD was undertaken, as well as whether the disorder was considered to be the primary or a co-morbid diagnosis in the treatment process. An explorative, descriptive- research design, utilizing a semi-structured interview format and a short survey of participants to provide descriptive statistics was used. Non-probability purposive snowballing sampling was used to gain access to psychiatrists and psychologists in both public or hospital service and independent private practice who met the inclusion criteria and who were willing to participate in the study. Interviews were conducted in English by the researcher. The major findings of the present study were categorized in three over-arching themes namely (1) views regarding the diagnosis of adults with ADHD, (2) experiences regarding the effects of impairment related to ADHD in adults, and (3) treatment and current care options for Adult ADHD. Sub-Themes were used to further explore the results. This study provides for a more in-depth understanding of Adult ADHD.

- Description: Attention Deficit Hyperactivity Disorder (ADHD)-related behaviour difficulties are said to be the cause of much of the disharmony and discord that exists within many families with ADHD-diagnosed children. On the basis of this understanding, a supplementary programme of behaviour modification, referred to as the Coping Skills Programme, was designed and implemented over a designated period of time, as a trial efficiency test, with a view to alleviate some of the family environmental stress caused by the effects of this disorder. There were three main aims to this research project, related to the research questions: Firstly, to establish to what extent this programme helped with the kinds of problems and difficulties being experienced by the parents of ADHD-diagnosed children and by the children themselves; secondly, to make recommendations regarding how to access and use such a programme and learn its skills, and thirdly to determine further ways with which to improve the Coping Skills Programme. The research design was based on Interpretive Theory and was qualitative in nature. An in-depth literature study was undertaken, which together with all the field notes acquired during the course of the study, formed the foundation of the study. A needs analysis was also carried out to ascertain the level and variety of ADHD-related needs that exist within the family unit. This needs analysis took place in the Nelson Mandela Metropole in the Eastern Cape to ascertain the level and variety of ADHD-related needs that exist within the family unit. The sampling selection of participants was both purposeful and dependent on availability, in order obtain as wide a range of information as possible, regarding specific ADHD-related criteria. This data was used as a foundation for the programme’s development. Information was gathered by means of phenomenological interviews, case study analysis, a focus group interview, field notes, observations and an audit trail. Measures were taken to ensure that the study was ethically conducted and trustworthiness maintained. The Coping Skills Programme was implemented with different families with ADHD-diagnosed children, within its designated time, which varied from family to family from between 8 and 10 weeks. Finally, three families were xx selected as case studies to substantiate the findings of this research study. Their selection was based on the range of the children’s age, the variety of their combined needs, the way in which each family dealt with the challenges posed by the programme, the parents’ involvement and the rate of success experienced by each family at the end of the allotted time. At the end of the programme’s implementation period it was found that confusion regarding parental role clarity and the role of the child in the home had a strong bearing on the treatment and management of ADHD-related difficulties. It was also found that the effect of parental unity and/or discord had a direct impact on ADHD-related behaviour. Equally important to the effective management of ADHD-related difficulties were the parental understanding and perceptions regarding their child’s ADHD-related needs and difficulties. The effectiveness of behaviour modification in relation to the level of parental involvement was also salient, as was the use of effective, positive communication to achievement of optimum results. Parental understanding of the role of discipline and how the effective use of this skill benefits the ADHD-diagnosed child became clear, as did the value of consistency in behaviour modification. The conclusion was reached that a programme as flexible as the Coping Skills Programme, when used appropriately and as a supplement to other forms of therapy, may be a significant source of assistance, support, encouragement and empowerment to families with members suffering with ADHD.

A needs analysis was also carried out to ascertain the level and variety of ADHD-related needs that exist within the family unit. This needs analysis took place in the Nelson Mandela Metropole in the Eastern Cape to ascertain the level and variety of ADHD-related needs that exist within the family unit. The sampling selection of participants was both purposeful and dependent on availability, in order obtain as wide a range of information as possible, regarding specific ADHD-related criteria. This data was used as a foundation for the programme’s development. Information was gathered by means of phenomenological interviews, case study analysis, a focus group interview, field notes, observations and an audit trail. Measures were taken to ensure that the study was ethically conducted and trustworthiness maintained. The Coping Skills Programme was implemented with different families with ADHD-diagnosed children, within its designated time, which varied from family to family from between 8 and 10 weeks. Finally, three families were xx selected as case studies to substantiate the findings of this research study. Their selection was based on the range of the children’s age, the variety of their combined needs, the way in which each family dealt with the challenges posed by the programme, the parents’ involvement and the rate of success experienced by each family at the end of the allotted time. At the end of the programme’s implementation period it was found that confusion regarding parental role clarity and the role of the child in the home had a strong bearing on the treatment and management of ADHD-related difficulties. It was also found that the effect of parental unity and/or discord had a direct impact on ADHD-related behaviour. Equally important to the effective management of ADHD-related difficulties were the parental understanding and perceptions regarding their child’s ADHD-related needs and difficulties. The effectiveness of behaviour modification in relation to the level of parental involvement was also salient, as was the use of effective, positive communication to achievement of optimum results. Parental understanding of the role of discipline and how the effective use of this skill benefits the ADHD-diagnosed child became clear, as did the value of consistency in behaviour modification. The conclusion was reached that a programme as flexible as the Coping Skills Programme, when used appropriately and as a supplement to other forms of therapy, may be a significant source of assistance, support, encouragement and empowerment to families with members suffering with ADHD.

- Description: This thesis uses the substainable rural livelihoods framework to investigate the agricultural livelihoods of the Cata community of the Eastern Cape. The Cata community is a deeply rural community located on the southern slopes of the Amatole Mountains. Traditional crop production used to be the major source of income for the households in this community. Of late there has been a lesser reliance on production of food by many households. Many are no longer ploughing their fields or their homestead gardens. People from this community are now spending most of their income on purchasing basic food items that they use to produce themselves, such as vegetables. The researcher then decided to study the contemporary livelihood of this rural community so as to identify the reasons why people in Cata are no longer ploughing their fields and gardens. This study found that, rural people in the community are faced with severe obstacles to agricultural production and this has led them to abandon agriculture as a major means of household support. These obstacles include high cost of production inputs, lack of fencing and lack of mechanization tractors and implements. In order to revitalize crop production the people want to be assisted with production inputs, tractor subsides, consistent water supply and fencing of the fields. Finally, the study makes recommendations for the revitalization of crop production in the Cata.

- Description: The aim of this project was to determine the extent to which an agricultural project contributes to the alleviation of poverty in a community. This was done through a case study of one agricultural project based in Kidds Beach, in the Eastern Cape. The research was conducted utilizing the qualitative research method. The findings depicted that the standard of living for the community had altered due the employment opportunities afforded by the project. The findings also illustrated the project is the only one of its nature in the Eastern Cape and that similar projects are in the process of being established in communities in the Transkei. The cultivation of macadamia nuts is costly and the target market is concentrated largely in Europe. The success of the first crop and the dividends procured, the project has proven itself to be a sound method of community and rural development which can encourage investment from other parties.

- Description: Women in South Africa are a vulnerable group, who face threats of violence and abuse daily. The worst aspect of this being domestic abuse or intimate partner violence. Domestic abuse between partners is a common occurrence that results not only from a power imbalance in the relationship but from expectations of society regarding the role of the woman and accepted behaviours, regarding the disciplining of the wife, that is held by communities. Despite attempts by law enforcement and the State to minimise and control domestic abuse; domestic abuse remains on the rise. These women find themselves unprotected and facing possible death at the hands of a loved one. In fear for their lives, these women resolve to kill their partners before their husbands kill them. This changes their status from victim to perpetrator. Consequently, they face prosecution.This dilemma is not unique to South Africa, and as a result, author Lenore Walker created Battered Woman Syndrome. This syndrome was created to explain the experience of these women and answer the questions as to why these women remain in these relationships. Also explained is why they feel trapped. This is a psychological theory that has been used by courts in Australia and the United States to assist the battered woman in justifying her actions when claiming self-defence. South Africa, however, has not made use of Battered Woman Syndrome when defending the battered woman in South African courts.

- Description: The Story of clay in the Grahamstown area can be dated as far back as 1812. In 1823 there was conflict between the Xhosa and the British Settlers over clay pits at Coombs valley, an area outside Grahamstown towards East London (Holleman, 1997, p. 50). Since the initial conflict, the mining of the resource has become a commercial activity. Pottery industries, brick making facilities and a kaolin mill were opened, with brick making being the only economically sustained activity which continues to present day. With the largest known deposits of quality kaolin in South Africa, the economic condition of the context of Grahamstown is not benefitting from the abundance of the raw-clay material (Malatji, 2010). The material is currently being mined at Strowan mine, the most active mine in the area, approximately 4km from Grahamstown and is transported to Johannesburg for milling. The transport costs involved in moving the material from the mine to the mill has impeded potential production. In 1988 the production of Kaolin from the Grahamstown area accounted for 55% of total local production in South Africa, but that figure had dropped to 27% by 2008 (Horan, 2008, p.1). The high waste factor and the cost implication involved in the erecting of the required infrastructure and equipment for a mill, become the main impediment to erecting a new Kaolin mill in Grahamstown. The raw material which is milled has a waste factor of approximately 90 percent, meaning that; of the material mined in the open cast mining method, less than 10 percent is transported to be milled (Burchell, 2015). Capital gain from production of kaolin in relation to the cost of the mill is inadequate to financially sustain the costs of erecting a kaolin mill for Grahamstown. A need for a by-product to utilize the high waste content of the mined product in a waste resourceful manner will potentially sustain a new mill economically. With the problem of transport and foreign provincial exploitation of local resources, a kaolin mill for Grahamstown will increase production and potentially become a catalyst for future development around kaolin supporting industries such as ceramics, paper industries, cosmetics and pharmaceuticals. This treatise is a strategic approach towards the design of a Kaolin mill with a brick making factory as a by-product of the waste of the high quality kaolin.

- Description: Background: South Africa has the highest number of people living with human immunodeficiency virus (HIV) infection in the world. In 2014, an estimated 10.2% of the population was HIV-positive which amounted to 5.51 million people. Efavirenz forms part of the triple therapy backbone used in South Africa and is part of the firstline treatment for HIV. Efavirenz has been strongly associated with causing neuropsychiatric side effects in at least 50.0% of patients to whom it is prescribed. These side effects cause hesitation amongst healthcare professionals to prescribe this agent to patients with active mental illnesses. Aim: The aim of the study was to evaluate the neuropsychiatric side effects of efavirenz in HIV-positive psychiatric and non-psychiatric patients and to determine whether this drug may be recommended for use in an HIV-positive psychiatric patient population. Method: The study was divided into two parts, namely a quantitative portion and a qualitative portion. The quantitative study was a prospective drug utilisation study, while the qualitative portion consisted of semi-structured interviews carried out with healthcare professionals working with people living with HIV/AIDS (PLWHA). The study included five municipal clinics in the Nelson Mandela Metropole as well as two public-sector psychiatric facilities in the Eastern Cape where medical records were reviewed to obtain the information required. Patients were followed in both instances for a period of 24 weeks with follow-up assessments carried out at two, four, 12 and 24 week intervals. In terms of the qualitative study, nurses at the clinics and doctors at the hospitals were contacted and appointments for interviews were made. The interviews were recorded using a voice recorder and were transcribed and analysed using theoretical framework analysis. Results: The review of 126 medical records at the clinics revealed that no patient had suffered from or complained of a neuropsychiatric side effect. This may indicate that patients were not suffering from clinically significant side effects, side effects were not being adequately recorded by healthcare staff, or the healthcare staff were not questioning patients regarding side effects. A total of 26 hospitalised patients were followed for 24 weeks in the psychiatric facilities. Almost half of the patients using efavirenz experienced an improvement in symptoms to the extent that they were iii discharged from the facility. The majority of patients (66.7%) not on an efavirenzcontaining regimen did not improve to the point of discharge. Healthcare staff were vague when providing a definition of neuropsychiatric side effects. There were conflicting ideas on whether or not efavirenz should be used in patients with an active psychiatric illness. Conclusions: Further studies need to be performed in public-sector institutions to obtain a clearer picture of the side effects experienced by patients using efavirenz. Healthcare staff need to be encouraged to keep complete records to allow for meaningful analysis. The further integration of mental health services into existing HIV programmes is essential for holistic treatment. Patients in psychiatric hospitals demonstrated that even patients with psychiatric disorders on efavirenz can experience positive outcomes and stabilisation of psychiatric symptoms, which may indicate that these may not have due to efavirenz use. Further elucidation concerning the use of efavirenz in patients with psychiatric disorders, a description of the neuropsychiatric side effects, as well as management strategies must be provided in subsequent HIV guidelines.

The increasing amount of illegal and negligent human-related activities within the Estuary has seen to an rise in degradation and destruction of our natural ecosystems with the issue of water pollution recently acquiring crisis stage. Being brought up in Uitenhage, the close proximity of the Swartkops River naturally served as an endless resource of outdoor activities over the years. Witnessing the current degraded state of my beloved river served as motivation for this treatise which is an attempt to address and reconcile our relationship with the natural environment. The issues facing the natural environment of Swartkops will be looked at in depth and sets of integrated interventions will be proposed in order to minimise further anthropocentric effects on nature. The project will attempt to develop a restorative design framework that will achieve ecological-, economical-, and social sustainability whilst voicing conservation awareness through the promotion of sustainable industry in the region. The project will address issues of natural degradation on various scales in order to develop an holistic approach that will restore and sustain the local- and national value of the Swartkops Estuary. The series of interventions will eventually lead to the design of a building located in Swartkops Village.
