- Description: The South African government has introduced mechanisms and plans to alleviate poverty and to monitor and evaluate the impact of the policies and programmes to the reduction of poverty. In its quest to eradicate and alleviate poverty, the government has prioritized poverty alleviation in its development agenda. In efforts to fight poverty, the government has since 1994, implemented various programmes that are aimed at alleviating poverty through stimulating employment, developing skills and improving service delivery. The poverty alleviation programme is one of the strategies that was implemented by the government, as a means to eradicate poverty. At the community level, depending on the nature of the programme, efforts have been made to incorporate mechanisms which enable poor people to play an active role in deciding how the benefits from programmes are distributed. The study was based on the projects identified by the community of Amajuba district in Dannhauser area in KwaZulu Natal. The Dannhauser Municipality in partnership with the Department of Agriculture and Environmental affairs have played a vital role in this regard by supporting the establishment of the Thuthukani project in 2004. In an attempt to assess the impact of the poverty alleviation projects, this study investigated the role played by the Thuthukani project in local economic development of the Dannhauser community in the Dannhauser Municipality. Participants included the Thuthukani project members, and the extension officer from the Department of Agriculture and Environmental affairs. The study found that, indeed poverty alleviation projects play a role in local economic development since they contribute towards job creation and improvement of the socio-economic status of the local community.

- Description: Organisations are continuously seeking for strategies to improve operations and gain competitive advantage. Maintenance tends to be a key management issue for many industrial companies. Maintenance management, being an integral part of manufacturing, can influence competitive companys‟ priorities, such as cost, quality and flexibility, and, hence, business strategy directly. The pharmaceutical industry also faces some unique challenges such as increasingly stringent safety and quality regulations, the effect of innovations in medical science and healthcare and a complex and costly design-to-market process (from product concept and development to market delivery). The industry is also going through turbulent times as it has to cope with challenges common to many other industries, how to deal with increasing competition, hold down costs, and expand. Regulatory compliance is one of the significant industry drivers for pharmaceutical companies. Regulations are enacted by government authorities to ensure public health and safety. The focus of regulation is on quality assurance and control in all areas such as receiving, manufacturing, storing, packaging, despatching and delivering. Apart from the required quality and safety checks, the regulations also mandate extensive record keeping of procedures, processes and systems. This treatise will investigate the maintenance management system of a pharmaceutical company and compare it to best practices. The true name of the pharmaceutical company that will be researched will not be disclosed for confidentiality reasons, instead it will be called My Pharmaceuticals. The company is based in Port Elizabeth. The research consists of a preliminary study to identify the problem areas in the maintenance management system within the company. A literature review of best practices in maintenance management systems combined with an investigation into the best pharmaceutical practices in maintenance management systems and regulatory controls are investigated and a model will be proposed to improve the current situation at the company.

- Description: In-car communication systems (ICCS) are becoming more frequently used by drivers. ICCS are used in order to minimise the driving distraction due to using a mobile phone while driving. Several usability studies of ICCS utilising speech user interfaces (SUIs) have identified usability issues that can affect the workload, performance, satisfaction and user experience of the driver. This is due to current speech technologies which can be a source of errors that may frustrate the driver and negatively affect the user experience. The aim of this research was to design a new multimodal interface that will manage the interaction between an ICCS and the driver. Unlike the current ICCS, it should make more voice input available, so as to support tasks (e.g. sending text messages; browsing the phone book, etc), which still require a cognitive workload from the driver. An adaptive multimodal interface was proposed in order to address current ICCS issues. The multimodal interface used both speech and manual input; however only the speech channel is used as output. This was done in order to minimise the visual distraction that graphical user interfaces or haptics devices can cause with current ICCS. The adaptive interface was designed to minimise the cognitive distraction of the driver. The adaptive interface ensures that whenever the distraction level of the driver is high, any information communication is postponed. After the design and the implementation of the first version of the prototype interface, called MIMI, a usability evaluation was conducted in order to identify any possible usability issues. Although voice dialling was found to be problematic, the results were encouraging in terms of performance, workload and user satisfaction. The suggestions received from the participants to improve the system usability were incorporated in the next implementation of MIMI. The adaptive module was then implemented to reduce driver distraction based on the driver‟s current context. The proposed architecture showed encouraging results in terms of usability and safety. The adaptive behaviour of MIMI significantly contributed to the reduction of cognitive distraction, because drivers received less information during difficult driving situations.

- Description: Despite the extensive research undertaken in the subject area of services marketing, much is still unknown to service providers of specific services in terms of firm-client relationships and how customer retention rates can be increased. This study attempts to address this limitation. The study revolves around the relationship marketing and customer retention of banks in South Africa, Canada and the United Kingdom (UK). Service firms, including banks, are vitally important to the economy of any country as they contribute to its Gross Domestic Product (GDP) (for example a 74 percent contribution in South Africa) and its employment rate. However, to survive in a complex, competitive business environment, service firms are required to focus on their clients’ needs. Banks can focus on their relationships with clients and measure their institutions’ success by considering their customer retention rates. When considering firm-client relationships and customer retention rates, it is important to gather and link the viewpoints of both clients and managers in order to ensure that firms perform according to clients’ needs. In order to establish the influence of selected variables on the relationship marketing and customer retention of banks, from the perspectives of both banking clients and managers, an empirical investigation was conducted. The primary aim of this study was to quantify significant relationships among selected variables; therefore the positivistic research paradigm was used. In addition, in designing the measuring instruments for the empirical investigation, the phenomenological paradigm was used. Thus, in order to use multiple sources of data, the strategy of methodological triangulation was adopted for this study. The samples consisted of banking clients and bank managers in South Africa, Canada and the UK. The empirical investigation conducted among banking clients revealed that significant positive relationships exist between six of the seven identified independent variables, namely communication, personalisation, empowerment, ethics, fees and technology, and banks’ relationship marketing. These relationships imply that, according to banking clients, if each of these aspects in banks improves, bank-client relationships would improve. The empirical investigation conducted among bank managers showed that managers only regard communication and fees as influencers of relationship marketing in banks. This result clearly indicated a difference in the viewpoints of banking clients and bank managers. In addition, the empirical investigation revealed that relationship marketing positively influences the customer retention of banks. This relationship implies that if a bank successfully maintains relationships with its clients, the bank’s customer retention rates will increase. Additionally, the empirical investigation revealed that the population group, education level and country of residence of banking client respondents exerted an influence on the perceptions clients have regarding banks’ relationship marketing and customer retention levels. If banking clients are African or are not educated with a qualification beyond secondary school level or are from Canada, they consider the relationship marketing of a bank to be more important and are more likely to be retained by banks. Generally, the study indicated that Canadian banking clients are more positive regarding the empowerment strategies and personalisation efforts of Canadian banks than South Africans are about those of South African banks. In addition, banking clients in the UK are more satisfied with the communication, fees and use of technology of UK banks than South Africans are about these aspects in South African banks. The study indicated that strategies to improve banks’ communication, personalisation, empowerment, ethics, fees and technology should be implemented by banks in ways to positively influence their relationship marketing and ultimately their customer retention. Strategies relating to each of these areas, successfully implemented by banks in Canada and the UK, are recommended to South African banks. In effect, these strategies will contribute to retail banks’ success, the competiveness in the banking industry, banking client benefits as well as the economic stability and prosperity of South Africa.

Specifically exploring and understanding the utilisation of personal experiences within counselling encounters, the practice of peer counselling within VCT, and the challenges experienced by HIV-positive lay counsellors within VCT settings. This study, employing a qualitative interpretative phenomenological methodology required a small sample of practicing HIV-positive lay counsellors, who were selected and interviewed on their experiences utilising semi-structured interviewing. Data was analysed for meaning units, which were interpreted inductively and hermeneutically, and categorised into super-ordinate themes. Three superordinate themes within the participants’ experiences of providing VCT services were determined, namely: ‘diagnosis and disclosure experiences’, ‘peer counselling’, and ‘challenges’. This research found that the experiences of providing peer counselling depended upon identification with their client’s negative appraisal of their diagnosis experiences. Whether through empathic connections generated through the shared experience of discovering a seropositive status, or through countertransferential reactions induced through their client’s yearning for care and support. This required the counsellor to selfdisclose within counselling encounters in order to provide personal experiences of living with HIV/AIDS. Successful implementation of peer counselling provided recently diagnosed individuals with knowledge surrounding HIV/AIDS, coping skills to manage the daily physiological and psychological challenges, facilitation and adherence to treatment, social assistance, ongoing relationships, inspiring hope, and the creation of positive appraisals. However the informal utilisation of task-shifting within lay healthcare cadres, and the lack of governmental recognition for the emotional labour provided within VCT indicated that HIVpositive lay counsellors require ongoing training, support and remuneration to limit potential occupational stress, resignation, and burnout.

- Description: Mathematics is regarded as a driving force in economies worldwide. The performance of South African learners in mathematics over the past decade has highlighted that problems are being experienced across all grades. This situation needs to be addressed with urgency. The South African Department of Education stated that quality learning must be the objective for all grades. The implementation of good teaching practices plays a crucial role in improving the quality of education and in guiding learners towards quality learning. To achieve quality mathematics teaching and learning it is imperative to determine what good mathematics teaching practices are. The identification of good mathematic teaching practices will provide a yard stick to measure the mathematics teaching competency of teachers. This study identifies a set of good mathematics teaching practice indicators and evidences applicable to teachers in the Intermediate phase as a first contribution. These indicators and evidences frame the second research contribution: an assessment instrument entitled “A Classroom Observation Tool for Observing Mathematics Teaching Practices in Primary Schools”. As a third research contribution a generic profile of a Grade four mathematics teacher has been built. This generic profile has been built through an analysis of data gathered by means of self-assessment questionnaires completed by the research sample, as well as through applying the observation tool. The value of the generic profile lies in the identification of shared strengths and shared improvement opportunities in the mathematics teaching practice of the sample and as such, it forms the basis of a theory on Grade four mathematics teaching practice. The fourth research contribution is the design and application of an intervention that addresses the shared improvement opportunities. The research study concludes by comparing pre-intervention classroom observation data with post-intervention classroom observation data and reporting on the impact of the intervention.

- Description: This research study investigates how selected Grade R teachers implement numeracy in their classrooms, based on their experiences, personal beliefs and perceptions. This study adopts the view that a teacher's practice is not only informed on what she believes about her learners, but also on how she organises her classroom environment and her own teaching practice. However, the teacher cannot be divorced from the political and historical background of Early Childhood Development (ECD), as these factors have an impact on her numeracy implementation. Integrated in this research study is thus not only a comprehensive historical analysis of the historical and political background of ECD, but also an in-depth look at the complex curriculum road the Grade R teacher had to travel over the past twelve years. The aim of this case study is to understand and describe what is happening in Grade R classrooms when numeracy is implemented, as well as identifying possible barriers which Grade R teachers may experience in implementing numeracy. The author utilized an adapted Interactive Qualitative Analysis Framework to explore Grade R teachers' views and experiences. Open-ended focus group interviews were used to develop a framework for individual interviews. This interview framework guided the data collection of nine audio-video tapes of classroom activities and nine semi-structured individual interviews. Analysis of the individual interviews revealed each teacher's understanding as well as her perceptions and needs regarding the implementation of numeracy in her classroom. The transcriptions of the individual interviews were compared to the audio-video tapes of what happened in each classroom. This was done in order to determine whether the teachers' practices were consistent with what they said in the interviews. Paradoxes and inconsistencies were documented. The historical and political analysis of ECD illustrates the complex development of ECD in South Africa over the last few decades. It therefore also highlights and brings to the fore the complex journey that Grade R teachers had to navigate in adapting their practice to ever changing curriculum requirements. The empirical results show that there are inconsistencies between what selected teachers know and believe, and what they are implementing. However, "silent themes" which did not come to the fore in the focus group or individual interviews, were identified in the audiovideo tapes of classroom activities. Also, many "silent themes" indicate that there are numerous concerns, such as lack of proficiency in bridging the gap between theory and practice, regarding the implementation of numeracy in Grade R. It was found that many of the selected Grade R teachers struggle to implement numeracy in their classrooms, as they lack the skills and support to teach numeracy in a Grade R context.

The author utilized an adapted Interactive Qualitative Analysis Framework to explore Grade R teachers' views and experiences. Open-ended focus group interviews were used to develop a framework for individual interviews. This interview framework guided the data collection of nine audio-video tapes of classroom activities and nine semi-structured individual interviews. Analysis of the individual interviews revealed each teacher's understanding as well as her perceptions and needs regarding the implementation of numeracy in her classroom. The transcriptions of the individual interviews were compared to the audio-video tapes of what happened in each classroom. This was done in order to determine whether the teachers' practices were consistent with what they said in the interviews. Paradoxes and inconsistencies were documented. The historical and political analysis of ECD illustrates the complex development of ECD in South Africa over the last few decades. It therefore also highlights and brings to the fore the complex journey that Grade R teachers had to navigate in adapting their practice to ever changing curriculum requirements. The empirical results show that there are inconsistencies between what selected teachers know and believe, and what they are implementing. However, "silent themes" which did not come to the fore in the focus group or individual interviews, were identified in the audiovideo tapes of classroom activities. Also, many "silent themes" indicate that there are numerous concerns, such as lack of proficiency in bridging the gap between theory and practice, regarding the implementation of numeracy in Grade R. It was found that many of the selected Grade R teachers struggle to implement numeracy in their classrooms, as they lack the skills and support to teach numeracy in a Grade R context.

- Description: The number of multinational enterprises has increased substantially. In part due to the integration of national economies (the European Union), improvements in communication and technology and the opportunity to reduce costs as a result of globalisation. Transfer pricing and especially business restructuring within multinationals is a fairly new concept.Professional legal and audit firms have different views on how to approach business restructurings. This research analyses important transfer pricing aspects and the anomalies that arise through business restructurings. The research method used in this research paper is primarily qualitative, comprising the analysis of various documentary sources of data. Relevant South African and international case law, tax legislation, the OECD Transfer Pricing Guidelines for Multinational Enterprises and Tax Administrations, the Transfer Pricing Aspects of Business Restructurings Discussion Draft and other reports were consulted and analysed. Further the views of recognised legal and tax experts that have been published in technical journals and text books were also considered and examined. A hypothetical example of a business restructuring transaction was constructed in order to illustrate practical issues and different approaches to solving them. The research has argued that the arm’s length principle, which forms the bases of transfer pricing regulation, is not an exact science but theoretically it is the most suitable measure.It may not be able to incorporate all variables, such as the cost savings through synergies of multinational enterprises, but it promotes international trade and investment by ensuring that transactions are based on fair prices. Business restructurings create anomalies in applying the arm’s length principle but these anomalies can be dealt with within the regulatory structure. The business restructuring approach recommended is realistic and pragmatic, but more clarity may be needed in certain circumstances. The research has also discussed the avoidance of transfer pricing audits, including having appropriate transfer pricing policies and documentation.

- Description: This study considers a Grade 9 Integrated Environmental Research Project which was implemented as a vehicle to induce knowledge-based change in learners. It was noted that change did not occur as hoped, and this study was undertaken to review the Grade 9 Project in order to improve it and to probe the apparent gap between knowledge and action. The study generated evidence on the learning processes within the project. This revealed a number of contradictions and tensions which limit change initiatives within the local environment. Notable here was a contradictory mandate between undertaking a research-based change project and responding to the rubric of assessment which was not linked to the research done. It was found that faced with this dual mandate, learners chose to focus on the assessment-laden mandate as this was the ultimate agenda that would reap the reward within the traditional school environment. The study examines the gap between knowledge and practice to probe ways in which to close this gap in the context of an environmental research assignment. The outcome is a recommendation that we as the project designers review the evidence of tensions and contradictions revealed in the study to reflect on the underlying purpose of the project and reshape it in light of recent literature on the challenges of social learning and change.

- Description: This research study examined public participation activities in Lady Frere during the LED strategy formulation process. Lady Frere is one of the three small towns constituting Emalahleni Local Municipality (ELM).A review of existing literature and legal frameworks suggest that authentic participation by the public occurs when the dimensions of representativeness, interactiveness, use of stakeholder/public inputs and the quality of public inputs are satisfied. The current study sought to identify conditions that would serve as a measurement to be satisfied before we can say authenticity was factored into the public participation effort during the Local Economic Development (LED) strategy formulation process in Lady Frere. A three-tier model was adopted to assess the performance of the ELM public involvement initiatives during the LED process. Key indicators of the four dimensions of authenticity were formulated and used to determine authenticity of these initiatives (programs).The data for this study came from analysing the LED strategy (2010-2015) document and the qualitative interviews held with purposively selected respondents. Nineteen respondents representing different institutions in Lady Frere agreed to be interviewed for the study. Organisations represented included public service institutions in operation in Lady Frere, private formal businesses in operation in the area and some civil society structures present in the town. The results of this study suggest that the municipality fell short of implementing public participation programs that achieved authenticity during the LED strategy formulation process. A careful and well-intentioned use of various public participation tools that embrace increased interaction between municipal employees and the public can assist in achieving better levels of authenticity in their public involvement initiatives. The willingness of municipal staff to adopt new ideas and innovations learned during public engagements is key to achieving higher levels of authenticity in their programs. Municipal participation programs would greatly benefit from training that increases individual acceptance of public participation as a valid service delivery mechanism. The researcher took opportunity to suggest the following recommendations for the ELM to work towards: Increased opportunities for occurrence of authentic public participation; Creation of individual ownership of authenticity in public participation; Creation of community partnerships to foster authenticity in public participation.

- Description: There are three lines of poverty in South Africa, the first line is that of people living at less than R271 per month and constitute one third of the population (about 33 percent), second being those people living at less than R422 per month (50 percent of the population) and the last group being people living at less than R1 230 per month, constituting 79.1 percent of the population (Oosthuizen. 2008: 7 – 9). The poorest provinces are Eastern Cape and Limpopo with a poverty rate of 68.3 percent and 60.7 percent respectively, Western Cape and Gauteng the poverty rates are 20 percent and 28.8 percent respectively (United Nations Development Programme. 2003) To respond to the poverty challenges the government has come up with poverty alleviation strategies which were later translated into anti-poverty programmes. The Anti-poverty programmes undertaken by Government since 1994 can be grouped into various categories of public expenditure such as (Friedman and Bhengu, 2008:14), Social assistance and grants, Employment generating programmes, enterprise development and income support, Basic household security, Social services, Disaster relief and Employment related social insurance. This study assessed Mogabane Community Project to find out reasons why the project did not reach its objective of poverty reduction in the community. Qualitative Research methodology was used to arrive at the findings.

- Description: South Africa has been experiencing a continuous bout of service delivery protests since the late 1990s. Protests are a public manifestation of conflict and therefore this study uses the term conflict and protest interchangeably. The cost of the damage which results from these protests is immense. It is critical that solutions to this protest ensure that the underlying factors leading to the protest are addressed, in order to reduce the probability of its reoccurrence. This study seeks to investigate whether or not service delivery conflict could be prevented through improved implementation of government services in all spheres. The provision of basic service delivery is critical for the livelihood of any community and even more so for previously disadvantaged communities. It is important to verify if the lack of, or poor, service delivery can lead communities to revolt against each other or the governing authority. The challenge with any conflict situation is that when it erupts into destruction, only the visible symptoms are addressed, because addressing the underlying factors is a long-term process which requires a holistic understanding of the conflict. Previously disadvantaged communities are experiencing a backlog of service delivery, the exploitation of their plight by different agencies and mismanagement by public servants, which further delays service delivery. The Ezakheni community has been one of those communities who were previously disadvantaged and expected different levels of government to meet their service delivery needs, from land ownership to the building of houses. This community expected that the process of improving their livelihood would be fast-tracked instead it was delayed by community conflict. The conflict started as a revolution against agencies that were against the community’s process of acquiring land, but ended up as community members fought each other and government departments in order to survive. The Ezakheni community conflicts date back to 1998 and subsided during late 2005. Any conflict after that was latent, although there were still killings, but they were sporadic and sometimes not linked to the conflict but categorised as criminal behaviour. The present study takes the reader through the process of evaluating whether or not there is a logical relationship between Ezakheni community conflict and service delivery. Chapter One gives an overview of the study and the processes that were followed during this study. Chapter Two opens up theoretical debates that influence the epistemology of this study. Chapter Three gives the reader a detailed overview of the profile of the case study. Chapter Four describes the methodology that has been utilised in the study. Chapter Five presents the data and interprets it. Chapter Six concludes the study.

- Description: Proactive coping involves individuals developing resources to facilitate their promotion toward personal growth. The aim of this study was to determine whether differences occurred in the use of a proactive coping style between students from various Southern African countries and universities, in order to form cross-cultural comparisons for this construct. The Proactive Coping Inventory (PCI) was electronically distributed to collect the empirical data, with purposeful non-probability sampling being employed. The sample consisted of 622 students from three universities, one each in Botswana, Namibia and South Africa. Eleven hypotheses were set for investigation. Exploratory factor analysis resulted in the emergence of two distinct factors in the PCI, implying two separate subscales. A statistically significant relationship was found between proactive coping and both instrumental and emotional support seeking. A small, practically significant gender difference was discovered for emotional support seeking, and moderate differences were found between age and proactive coping. Southern African university students exhibit higher levels of proactive coping than preventative coping, strategic planning or emotional support seeking. Furthermore, they make use of proactive coping to a greater extent than individuals outside of the Southern Africa region. In terms of national and institutional culture, no statistically significant differences occurred for proactive coping between any of the countries or universities under study. These findings imply that regardless of a Southern African student's home country or university, he or she is likely to cope proactively. A possible explanation is because Africans generally value social support systems and collectivism, which assist individuals in coping proactively. These results also suggest that all three universities under study are effectively encouraging students to cope in a proactive manner, whether formally or informally, which is in line with the values of these institutions. It is recommended that Southern African universities focus more intentionally on becoming positive socialising systems through integrating the development of human strengths, thus enhancing the value that students and society gain from tertiary education. These findings add to the current body of knowledge relating to proactive coping, which is lacking in a Southern African context.

- Language: English
- Type: Thesis , Masters , M Ed

- Description: Parental involvement is one of the key requirements that are laid down by fundamental policies on schooling in South Africa. The policies include National Education Policy Act No 27 of 1996 and South African Schools Act No 84 of 1996. However, various schools in this country have generally not met this requirement effectively. The situation is more prevalent in the rural schools where parents either do not participate at all or their participation is minimal. The researcher investigated the factors that were behind the lack of parental involvement in rural schools. A specific focus was in rural schools of Mthatha District. The schools were chosen because of their proximity to the researcher and noted constant reports on the lack of parental involvement. The primary targeted population were the parents whose learners were schooling in the two selected rural schools of Mthatha District, which were Pazima J.S.S and Xonyeni J.S.S The researcher used stratified sampling to ensure better coverage of population and to achieve better precision or accuracy. This was done by dividing the parents into homogenous groups like, gender, age, sex and etc. The researcher used both quantitative and qualitative research methods. The designs that were used were survey and interviews. Questionnaires and interview schedule were developed and administered to parents of the two selected schools. These methods were judged to be appropriate as some of them might not be able to read and write. In addition to that, it was within acceptable procedures of collecting data in both qualitative and quantitative study. There were limitations and delineations and some of them included that the study was confined only to Mthatha District. The researcher selected only two schools and other schools were excluded. The study investigated only parents of the senior phase level and other phases were not involved. The researcher collected data from the parents of two selected schools i.e. Pazima J.S.S and Xonyeni J.S.S using questionnaires and interviews. Questionnaires were administered to parents who were able to read and write and for those parents who could not read and write interviews were conducted. The data was analysed using a pool- table method and out of 74 parents used as the sample for the study most parents were ranging between 32 and 39 years. The study was dominated mainly by female parents and most parents had learners in grade 8&9. Most of the parents in the study were married and they were unemployed with J.S.S. as their highest qualification. The six research questions asked were: (a) Is lack of relationship between the schools and the homes of learners one of the causes for lack of parental involvement in rural schools of Mthatha District? (b) Is lack of co-operation by parents in the education of their children one of the causes for lack of parental involvement in rural schools of Mthatha District? (c) Is illiteracy of parents one of the causes for lack of parental involvement in rural schools of Mthatha District? (d) Is employment of parents one of the causes for lack of parental involvement in rural schools of Mthatha District? (e) Is lack of parental participation in school governance and management one of the causes for lack of parental involvement in rural schools of Mthatha District? (f) Is lack of communication between parents and the teachers one of the causes for lack of parental involvement in rural schools of Mthatha District? The findings showed that there was no relationship between the schools and the homes of learners and parents were co-operating at all. Most of the parents were illiterate, unemployed married females who have cultural activities to perform which made them not to be involved in their schools. Communication between the schools and homes of the learners was lacking and parents were not actively participating in school governance and management in their schools. The recommendations from this study were that, for lack of co-operation workshops for both parents and teachers on team building and teacher – parent relations were recommended. For illiteracy problem implementation of ABET classes was recommended. Circulars issued by the Department relating to parental involvement should be read and discussed by both parents and teachers. Communication skills needed to be improved so as to maintain good home-school relationship. Workshops on how to elect school governing bodies and on their roles and their responsibilities were recommended. In conclusion parents are very important stakeholders in education so they need to be highly involved in the education of their children.

This was done by dividing the parents into homogenous groups like, gender, age, sex and etc. The researcher used both quantitative and qualitative research methods. The designs that were used were survey and interviews. Questionnaires and interview schedule were developed and administered to parents of the two selected schools. These methods were judged to be appropriate as some of them might not be able to read and write. In addition to that, it was within acceptable procedures of collecting data in both qualitative and quantitative study. There were limitations and delineations and some of them included that the study was confined only to Mthatha District. The researcher selected only two schools and other schools were excluded. The study investigated only parents of the senior phase level and other phases were not involved. The researcher collected data from the parents of two selected schools i.e. Pazima J.S.S and Xonyeni J.S.S using questionnaires and interviews. Questionnaires were administered to parents who were able to read and write and for those parents who could not read and write interviews were conducted. The data was analysed using a pool- table method and out of 74 parents used as the sample for the study most parents were ranging between 32 and 39 years. The study was dominated mainly by female parents and most parents had learners in grade 8&9. Most of the parents in the study were married and they were unemployed with J.S.S. as their highest qualification. The six research questions asked were: (a) Is lack of relationship between the schools and the homes of learners one of the causes for lack of parental involvement in rural schools of Mthatha District? (b) Is lack of co-operation by parents in the education of their children one of the causes for lack of parental involvement in rural schools of Mthatha District? (c) Is illiteracy of parents one of the causes for lack of parental involvement in rural schools of Mthatha District? (d) Is employment of parents one of the causes for lack of parental involvement in rural schools of Mthatha District? (e) Is lack of parental participation in school governance and management one of the causes for lack of parental involvement in rural schools of Mthatha District? (f) Is lack of communication between parents and the teachers one of the causes for lack of parental involvement in rural schools of Mthatha District? The findings showed that there was no relationship between the schools and the homes of learners and parents were co-operating at all. Most of the parents were illiterate, unemployed married females who have cultural activities to perform which made them not to be involved in their schools. Communication between the schools and homes of the learners was lacking and parents were not actively participating in school governance and management in their schools. The recommendations from this study were that, for lack of co-operation workshops for both parents and teachers on team building and teacher – parent relations were recommended. For illiteracy problem implementation of ABET classes was recommended. Circulars issued by the Department relating to parental involvement should be read and discussed by both parents and teachers. Communication skills needed to be improved so as to maintain good home-school relationship. Workshops on how to elect school governing bodies and on their roles and their responsibilities were recommended. In conclusion parents are very important stakeholders in education so they need to be highly involved in the education of their children.

- Description: The study set out to investigate the challenges faced by NGOs in carrying out supplementary feeding programmes in Zimbabwe’s rural areas. CARE and PLAN International in Zimbabwe were the two NGOs used as case studies and their operations in the Lower Gweru district of the Midlands Province Zimbabwe provided the empirical data for this study. This study was principally qualitative in nature as it sought to provide an in-depth analysis of the main challenges that NGOs face when carrying out supplementary feeding programmes in the rural areas of Zimbabwe. For the purpose of collecting data the study relied on Focus Group Discussions, in-depth interviews with key informants and document study. The key informants included Country Directors, Programme and Field officers at both CARE and PLAN International who had intimate knowledge of some of the challenges that their supplementary feeding programmes faced. Challenges that faced CARE and Plan International’s supplementary feeding programmes were categorized into two themes, internal and external organizational challenges. Internally the study revealed that the NGOs were unable to retain critical personnel such as nutritionists and programme officers. It also emerged from the study that field officers were involved in the thefts of food meant for the supplementary feeding programmes. The management of the supplementary feeding programmes was made difficult by lack of adequate information about the target beneficiaries. Further the study noted that there were contestations when it came to the selection of the beneficiaries of the programme. It was also found that during the rainy season it was difficult to 8 avail food timeously to the beneficiaries of the supplementary feeding programmes. It emerged from the study that supplementary feeding programmes were victims of political interference as the government and war veterans were suspicious that the programmes were being used to influence the voting behavior of the recipients. The global financial crisis also limited the capacity of the donors to continue availing substantial amounts of money for food procurement. As part of the broader strategy to increase the effectiveness of the NGOs in carrying supplementary feeding programmes this study recommended that NGOs should re-strategize on how they remunerate key personnel such as nutritionists. The NGOs through their mother body NANGO should constantly engage government so that there is a good working relationship supportive of poverty reduction through supplementary feeding programmes.

- Description: A stable money demand function plays a vital role in the analysis of macroeconomics, especially in the planning and implementation of monetary policy. With the use of Johansen cointegration and error correction model estimates, this study examines the existence of a stable long-run relationship between real money demand (RM2 and RM3) and its explanatory variables, in South Africa, for the period 1990-2009. The explanatory variables used in this study are selected on the basis of different monetary theories and empirical works, including the Keynesian, Classical and Friedman’s modern quantity theory of money. Based on these theories, the explanatory variables used in this thesis are real income, an interest rate, the inflation rate ,the exchange rate and foreign interest rate. The signs of the coefficients of the variables are as expected from economic theory. The coefficients of real income, the exchange rate and foreign interest rate are positive, while the coefficients of the interest rate and inflation rate are negative. This study augments the cointegration and vector autoregression (VAR) analysis with impulse response and variance decomposition analyses to provide robust long run effects and short run dynamic effects on the real money demand. In addition a foreign interest rate to capture the impact of capital mobility on money demand in South Africa was used. Results from the Johansen test suggest that real money demand (RM2 and RM3) and its all explanatory variables are cointegrated. Hence, there is a long-run equilibrium relationship between the real quantity of money demanded and five broadly defined macroeconomic components namely, real income, an interest rate, the inflation rate, foreign interest rate and the exchange rate in South Africa. Overall, the study finds that the coefficients of the equilibrium error terms are negative, as expected, and significantly different from zero, implying that 0.16 and 0.1 of the discrepancy between money demand and its explanatory variables is eliminated in the following quarter. Application of CUSUM and CUSUMSQ stability test showed that real money demand (M2 and M3) is stable in South Africa. The impulse response analysis provided evidence that the real M3 money, national income, rate of inflation and the foreign interest rate have a significant impact on the real M3 money demand in the short run. However, remaining variables (the real exchange rate and prime overdraft rate), have only a transitory effect on the real M3 money demand. There was further evidence that real exchange rate, the rate of inflation and the foreign interest rate, have a significant impact on the real M2 money demand in the short run. However, remaining variables (the national income and prime overdraft rate), have only a transitory effect on the real M2 money demand. Results from the variance decompositions of the real money demand are basically similar to those from the impulse response analysis and reveal that the fundamentals explain some, but not all, of the variations of the real money demand. The results showed that the national income explains the largest component of the variation in the real M2 money demand followed by the exchange rate and foreign interest rate. Shocks to the other variables continued to explain an insignificant proportion of the variation in the real M2 money demand. The national income also explains the largest component of the variation in the real M3 money demand followed by the foreign interest rate and exchange rate. Shocks to the other variables continued to explain a less significant proportion of the variation in the real M3 money demand.The study finds that both real M2 and M3 are stable which makes monetary targeting a viable policy option for the SARB. , Thesis (MCom) -- Faculty of Management and Commerce, 2011

An investigation into the effect of carbon type addictives on the negative electrode during the partial state of charge capacity cycling of lead acid batteries

- Description: It is well known that a conventional lead acid cell that is exposed to a partial state of charge capacity cycling (PSoCCC) would experience a build-up of irreversible PbSO4 on the negative electrode. This results into a damaged negative electrode due to excessive PbSO4 formation by the typical visual “Venetian Blinds” effect of the active material. This displays the loss of adhesion of the active material with the electrode’s grids thereby making large sections of the material ineffective and reducing the cells useful capacity during high current applications. The addition of certain graphites to the negative paste mix had proven to be successful to reduce this effect. In the first part of the study, the physical and chemical properties of the various additives that are added to the negative electrode paste mix were comparatively studied. This was done to investigate any significant differences between various suppliers that could possibly influence the electrochemical characteristics of the Pb-acid battery performance. This comparative study was done by using the following analytical techniques; BET surface area, laser diffraction particle size, PXRD, TGA-MS and SEM. The study showed that there were no significant differences between the additives supplied from different suppliers except for some anomalies in the usefulness of techniques such as N2 adsorption to study the BET surface area of BaSO4. In order to reduce the sulphation effect from occurring within the Pb-acid battery a number of adjustments are made to the electrode active material. For example, Pb-acid battery manufacturers make use of an inert polymer based material, known as Polymat, to cover the electrode surfaces as part of their continuous electrode pasting process. It is made from a non woven polyester fiber that is applied to the pasted electrodes during the continuous pasting process. In this study the Polymat pasted electrodes has demonstrated a better physical adhesion of the active material to the grid support thereby maintaining the active material’s physical integrity. This however did not reduce the sulphation effect due to the high rate partial state of capacity cycling (HRPSoCCC) test but reduced the physical damage due to the irreversible active material blistering effect. The study investigated what effect the Polymat on the electrodes has on the III battery’s Cold Cranking Ability (CCA) at -18 degree C, the HRPSoCCC cycling and its active material utilization. The study showed that there was little or no differences in the CCA and HRPSoCCC capabilities of cells made with the Polymat when compared to cells without the Polymat, with significant improvement in active material’s adhesion and integrity to the grid wire. This was confirmed by PXRD and SEM analysis. Negative electrodes were made with four types of graphites (natural, flake, expanded and nano fibre) added to the negative paste mixture in order to reduce the effect of sulphation. The study looked at using statistical design of experiment (DoE) principles to investigate the variables (additives) such as different graphites, BaSO4 and Vanisperse to the negative electrode paste mixture where upon measuring the responses (electrochemical tests) a set of controlled experiments were done to study the extent of the variables interaction, dependency and independency on the cells electrochemical properties. This was especially in relation to the improvement of the battery’s ability to work under HRPSoCCC. The statistical analysis showed that there was a notable significant influence of the amounts of vanisperse, BaSO4 and their respective interactions on a number of electrochemical responses, such as the Peukert constant (n), CCA discharge time, material utilization at different discharge rates and the ability to capacity cycle under the simulated HRPSoCCC testing. The study did not suggest an optimized concentration of the additives, but did give an indication that there was a statistical significant trend in certain electrochemical responses with an interaction between the amounts of the additives BaSO4 and Vanisperse. The study also showed that the addition of a small amount of Nano carbon can significantly change the observed crystal morphology of the negative active material and that an improvement in the number of capacity cycles can be achieved during the HRPSoCCC test when compared to the other types of graphite additives.

- Description: This study aimed to provide South African advertising professionals with insights into the current state of online and mobile advertising in South Africa, highlighting areas in which this sector of the industry can develop in order for professionals to perpetuate successful and innovative use of the mediums available to them and their clients. The study draws on literature from the fields of traditional advertising, digital advertising and new media. Research on the South African digital advertising climate is not as readily available as that of international studies based in the United States of America and the United Kingdom. The study therefore used two data collection methods namely, telephonic semi-structured interviews with advertising professionals employed within the South African advertising and marketing industries as well as an electronic survey also aimed at advertising professionals employed within the South African advertising and marketing industries. The data collected aims to provide an insight into the professional opinions and feelings of these professionals as to how the South Africa digital advertising landscape is perceived, how it compares to its international counterparts and whether online and mobile technologies have had an impact on the South African advertising industry in terms of ad-spend not only on digital but on traditional advertising. The data from both the semi-structured interviews and survey were analysed in terms of the aforementioned aspects and correlations were found between the qualitative and quantitative data. Five advertising professionals from various agencies from around South Africa were interviewed telephonically while 27 advertising professionals attempted the electronic survey with 21 completing the survey. The study found that advertisers acknowledge that online and mobile technologies have had an impact on the South African advertising industry as digital advertising is now seen as an important fixture within the advertising industry and is considered to now be as important as traditional advertising. However, although advertising professionals acknowledge this importance, the medium is still underutilised due to a number of determining factors. These factors include insufficient knowledge in the field of digital advertising by advertisers and clients as clients are still unwilling to allocate similar levels of ad-spend to digital as they would to traditional advertising, this despite a notable increase in digital ad-spend. Traditional advertising still dominates ad-spend and advertisers are of the opinion that despite the growth of digital media, this trend will remain prevalent in South Africa which continues to trail behind its international counterparts.

- Description: Basic Antenatal Care (BANC) is a way of training or upgrading the knowledge and skills of all nurses, midwives and doctors involved in antenatal care at the primary health care level so that the minimum care can be provided effectively. This study was conducted to investigate the implementation of the BANC program by midwives in the Mdantsane clinics during February 2009. Methods: A descriptive study design was undertaken targeting midwives providing antenatal care to pregnant women, in 14 clinics of Mdantsane. Data was collected from 25 midwives in the clinics, and from 140 ANC cards of women attending ANC on the day of their visit to the clinic. Results: The majority of midwives providing BANC in Mdantsane clinics were not trained in BANC. There were 10 trained midwives and 15 not yet trained. A total of twenty five midwives were involved in the study. The number of visits according to the BANC schedule was well known by the midwives in the study. The content of the visits was well known for the first visit, but for subsequent visits, the participating midwives could not state exactly what they do on these visits. They perceived BANC as something beneficial for both midwives and pregnant women with 24 of the participating midwives rating BANC as advantageous. In completing an ANC card, the midwives scored between 48 percent and 100 percent. Under examination, they scored between 52 percent and 100 percent. Lastly on interpretation and decision making, they scored between 0 percent and 92 percent. This could have troubling consequences for the health status of the mother and baby. Weaknesses in providing antenatal care identified in the study included participating midwives failing to fill in the last normal menstrual period (LNMP) and the estimated date of delivery (EDD), which was a worrying observation. Plotting of the gestational age at first visit was also not carried out well as only 47 percent of the midwives in the study did this, meaning that there would be a miscalculation of the gestational age thereafter throughout the pregnancies. The body mass index (BMI) was not calculated as the maternal height and weight were not written on the ANC card. This should be completed in order to check the nutritional status of the pregnant woman to help supplement, if malnourished, and educate on diet, if overweight. Only 17 percent of the midwives in the study plotted the foetal presentation. Failure to plot foetal presentation could lead to complications during delivery because women with abnormal presentations could end up delivering in a clinic instead of the hospital.Conclusion: This study showed that even though midwives are implementing BANC among pregnant women, it is not being carried out correctly. Therefore the programme will not be as beneficial as it would be if put into practice correctly. This is highlighted by the lack of knowledge from the untrained midwives regarding the content of care on subsequent visits. Thus there is an urgent need for BANC training to be conducted and monitored at various sites.

- Description: Basic Antenatal Care (BANC) is a way of training or upgrading the knowledge and skills of all nurses, midwives and doctors involved in antenatal care at the primary health care level so that the minimum care can be provided effectively. This study was conducted to investigate the implementation of the BANC program by midwives in the Mdantsane clinics during February 2009. Methods: A descriptive study design was undertaken targeting midwives providing antenatal care to pregnant women, in 14 clinics of Mdantsane. Data was collected from 25 midwives in the clinics, and from 140 ANC cards of women attending ANC on the day of their visit to the clinic. Results: The majority of midwives providing BANC in Mdantsane clinics were not trained in BANC. There were 10 trained midwives and 15 not yet trained. A total of twenty five midwives were involved in the study. The number of visits according to the BANC schedule was well known by the midwives in the study. The content of the visits was well known for the first visit, but for subsequent visits, the participating midwives could not state exactly what they do on these visits. They perceived BANC as something beneficial for both midwives and pregnant women with 24 of the participating midwives rating BANC as advantageous. In completing an ANC card, the midwives scored between 48 percent and 100 percent. Under examination, they scored between 52 percent and 100 percent. Lastly on interpretation and decision making, they scored between 0 percent and 92 percent. This could have troubling consequences for the health status of the mother and baby. Weaknesses in providing antenatal care identified in the study included participating midwives failing to fill in the last normal menstrual period (LNMP) and the estimated date of delivery (EDD), which was a worrying observation. Plotting of the gestational age at first visit was also not carried out well as only 47 percent of the midwives in the study did this, meaning that there would be a miscalculation of the gestational age thereafter throughout the pregnancies. The body mass index (BMI) was not calculated as the maternal height and weight were not written on the ANC card. This should be completed in order to check the nutritional status of the pregnant woman to help supplement, if malnourished, and educate on diet, if overweight. Only 17 percent of the midwives in the study plotted the foetal presentation. Failure to plot foetal presentation could lead to complications during delivery because women with abnormal presentations could end up delivering in a clinic instead of the hospital.Conclusion: This study showed that even though midwives are implementing BANC among pregnant women, it is not being carried out correctly. Therefore the programme will not be as beneficial as it would be if put into practice correctly. This is highlighted by the lack of knowledge from the untrained midwives regarding the content of care on subsequent visits. Thus there is an urgent need for BANC training to be conducted and monitored at various sites.
