- Description: Continued debates on economic development, poverty eradication and the growing skeptism concerning the paradigms proposed through many decades, has led to a continued search for a paradigm that would, finally, resolve the issue of pervasive poverty in the Sub-Saharan Africa. Having implemented decentralization within government entities without any significant contribution to poverty eradication, the focus has now turned to the development agencies themselves. What are the inefficiencies in these agencies which if addressed might enable them deliver development aid more efficiently thus, providing more resources for development from being lost in the attrition of overheads? It is, therefore, argued that decentralization of development agencies will improve the efficiency and effectiveness of IFIs in delivering development aid. At the same time, decentralization reforms have been proposed as a response to the failures of highly centralized states (or organizations in this case). Empirical evidence, strongly, suggests that physical proximity and more "face-time", promotes better results-on-the-ground, delivered by staff who are better attuned to local conditions and have a better understanding of the client and their development agenda. But, will decentralization alone solve the issue of pervasive poverty? This research recognises that the factors affecting poverty are diverse and intricate and isolating just one part of the puzzle is not enough. Nevertheless, it is argues that decentralization, has a positive impact on poverty reduction thus, this study presents both practical and theoretical considerations from which policy measures can be derived. This thesis focused on establishing how the World Bank, changed its strategies through the implementation of decentralization of its operations as proposed in the ‗Strategic Compact‘, renewed the way it worked in order to maintain its relevance in the development world. The World Bank President, James Wolfensohn, proposed the Compact as a solution to the organization‘s self diagnosis that it was in distress, in a state of possible decline and was not fulfilling its mission of poverty eradication. This research, using Uganda Country Office as a case study, undertook, mainly, a qualitative review of the overall strategy of decentralization and its implementation organization wide and specifically, in Uganda. The research examined how the implementation of the strategy impacted on poverty trends in Uganda. This research found that the decentralization strategy was, fundamentally, the right one to deliver better results of the Bank‘s mission of ‗fighting poverty for lasting results‘ and its vision of ‗A World Free of Poverty‘. Contrary to the popular notion that the World Bank has been, largely ineffective in the delivery of its mission and its decentralization strategy just another one of its 'shams‘, this research established that the implementation of the strategy, although not having a direct or causal relationship, did have positive impact on poverty alleviation in Uganda. This study, therefore, makes a case for decentralization of donor organizations as a means of better delivery of the poverty eradication agenda in the developing world. The benefits though hard to measure in monetary terms are, nevertheless, real in terms of faster and better quality engagement with the clients which in turn, result into better delivery of services and programmes.

- Description: One of the key challenges that continue to confront governments, worldwide, with regard to development management, other than the obvious limited resources to meet the overwhelming and competing needs of the constituencies, is the efficiency and effectiveness of the state machinery. Within state machinery itself the major issue that is viewed as a primary shortcoming is the process of translating sound development policies into implementable programmes and projects. Within the processes of policy implementation the key weaknesses appear to lie on planning processes. As such, governments continue to cite poor alignment between policies, plans and priorities across various spheres of government, a challenge that manifests itself in a lack of integrated service delivery, duplication in application of resources and efforts, lack of sustainability of development initiatives, slow pace and poor quality of services provided to communities. This study was aimed at evaluating the nature and extent of alignment between the Strategic Performance Plans of selected Eastern Cape provincial government departments and the Provincial Growth and Development Plan (PGDP): 2004-2014. The main objectives of the study were to gain insight into the nature and extent of alignment between the Strategic Performance Plans of selected Eastern Cape provincial government departments and the PGDP objectives, indicators and targets; identify the new service delivery mechanisms, policies, procedures and change management plans that have been introduced, if any, to ensure the successful implementation of the PGDP programmes; and indentify risks and challenges that pose a threat to the successful implementation of the PGDP programmes and provide preliminary risk response strategies. Of paramount importance is that this study was not limited to assessing the nature and extent of harmony or strategic fit between a macro-provincial plan, known as the PGDP, and sector specific plans, called Strategic Performance Plans, but it sought to determine the bases of alignment, where it exists, and sources of misalignment where planning disjuncture are found. To this end, the study was intended to generate a conceptual framework for assessing alignment of plans within public institutions across all levels of government. Ten provincial government departments drawn from the four provincial administrative clusters that feed their work into, and hence accountable to various Cabinet Committees and, ultimately, Cabinet, participated in the study. Key issues that emerged, and remained unresolved, during the direct engagement of provincial government departments were consolidated and verified, later on, with the public entity that supports the Office of the Premier on matters of macro-policy and strategy development and socio-economic research, known as the Eastern Cape Socio Economic and Consultative Council (ECSECC). This study followed a qualitative research methodology approach. Strategic Performance Plans of selected provincial government departments were analysed to establish linkages with the PGDP. A standard Alignment Evaluation Matrix was utilized to provide the results of content analysis of departmental plans. This Matrix was developed based on extensive literature study conducted that yielded a working Strategic Planning Alignment Model. The results of analysis of departmental plans and the key features of the Planning Alignment Model formed the basis of engagement of selected government departments during field study. Managers and officials working in components such as Strategic Planning, Monitoring and Evaluation, Special Programmes, infrastructure Planning, Demand Management and Research, Budget Planning and Control, Municipal Support, Geographic Information Systems and Spatial Planning, participated in the focus groupdiscussions. This study revealed both positive and negative factors on how provincial government departments have, over time, attempted to give effect to the intentions of the Provincial Growth and Development Plan; 2004-2014. Firstly, the study demonstrated that the PGDP was viewed in the same light as any other planning framework generated at national and local government level, with its priorities and targets found in the same basket of policy issues that are competing for limited resources. Secondly, it was found that the PGDP has, over time, degenerated in terms of its strategic significance in the planning environment, with new priorities that have emerged at a national government level securing more attention of politicians and senior administrators at the detriment of the PGDP intentions. Political championing of the PGDP was viewed as having dwindled from one term of government to the next. As such, the PGDP was not found to be having the level of significance and traction that the regionalist-planning paradigm is beginning to suggest within the global policy development discourse. Thirdly, the study revealed that while plans of selected government departments had a sound articulation of the PGDP goals, this did not translate into well-costed operational plans with clear targets and timelines that link to the 2014 targets. Organisational structures and service delivery models of the selected government departments had not fundamentally changed since the PGDP was introduced in the Province. Incremental changes to departmental processes have been seen since the PGDP came into effect. The changes were more influenced by new priorities that emerged at national government level. As such, provincial government departments continued to be more inclined towards sector priorities which could be viewed as unfunded provincial priorities. As such, budget allocation to PGDP programmes was limited from department to department, due to competing national priorities. One argument advanced for this disjuncture in planning was that the PGDP itself should have, from time to time, been reviewed to consider priorities that might have emerged at national and local government sphere, including conditions that have changed in the socio, economic and political environments. This seemed not to have happened, despite a Planning Coordination and Monitoring Unit being established within the Office of the Premier, during PGDP inception, for this explicit purpose. Fourthly, the study noted the challenge of different planning cycles between the provincial and local government spheres, which was viewed as promoting planning disjuncture within the two spheres. This was pointed out as of critical importance in alignment since provincial government departments are expected to respond to community needs that are embodied in Integrated Development Plans of municipalities. For this vertical integration to happen, the study revealed that there has been over-reliance in inter-governmental structures which were relatively weak in various municipalities. In the same vein, horizontal integration at provincial government level seemed to be a challenge also due to the ineffectiveness of the cluster system introduced since 1999. While part of a Cluster system, and submitting plans and reports to Clusters, provincial government departments continued to work in silos. Priority setting, spatial targeting and resource allocation has remained a competency of individual provincial departments. The cluster budgeting and programme implementation envisaged in the PGDP was still to be seen, and it appeared that there was no Treasury tool to give effect to this noble intention. In fact, this intention was viewed as contradictory with the spirit of the Public Finance Management Act, 1999 that places single financial accountability on Heads of Departments, as individuals rather than a group or cluster. Fifthly, the study further revealed that the PGDP itself had design deficiencies that created a challenge for implementation, monitoring and evaluation. The PGDP was viewed as straddling between being a strategic framework that guides socio-economic planning, with a longer-term focus, and being a provincial plan. The PGDP was also found to be an all encompassing plan that contains a basket of everything that a provincial government would be expected to do. A viewpoint advanced herein regards international experience which suggests that being strategic means being selective, sorting the critical few from the important many, and giving that selection a ‘bite’ by shifting resources and demanding performance sufficient to make the desired impact. The latter was viewed as a fundamental shortcoming of the PGDP. In fact, the study revealed that some of the PGDP programmes were underway within provincial government departments even before the PGDP was formulated. Whether those programmes would serve the province achieve the few outcomes it set itself for 2014, is a matter the PGDP design could not confirm. It also transpired that a number of provincial departments were not adequately consulted during the determination of PGDP targets. Furthermore, it has emerged that the province lacks coherent competency at a level higher than provincial departments, which is capacitated with a pool of analysts possessing a deeper appreciation of various government sectors and the provincial economy. This competency would include development planners, spatial planners, sector policy analysts, researchers and other technical skills.

- Description: The research presented in this thesis investigates challenges faced by principals in historically disadvantaged schools in terms of their role as instructional leaders facilitating the implementation of curriculum policies. The study consists of two parts. The first study sampled 25 school principals, 80 teachers and 11 department of education officials from the Uitenhage and Port Elizabeth education districts in the Eastern Cape. Data obtained in the first study were generated by administering a pen-and-paper questionnaire and individual interviews to selected participants. The second study employed an online questionnaire that was open to principals, teachers and departmental officials in all provinces of South Africa in order to generate data over as wide a geographic range as possible. Mixed methods were used to analyse the qualitative and quantitative data from the two studies. Thematic analysis techniques were employed to categorise qualitative data and the quantitative data were subjected to analytical techniques to provide descriptive and inferential statistics. The data revealed that school principals view themselves as change agents who should be in the forefront of change and curriculum implementation, and that they believe that they know what is expected of them in this regard. However, they recognise that they are not adequately prepared for the task of instructional leadership. The data also suggest that teachers have expectations that principals should be trained in instructional leadership and work closely with departmental officials in order to provide guidance and leadership at school level to address their professional needs. Problems related to capacity and skills of subject advisors and other district officials were revealed by the study. These issues are generally and informally recognised, but have not been formally raised within the Department of Education. The findings of the study also highlight the fact that, after nearly two decades in the new political dispensation, there are still vast differences within the South African schooling system between school types. These differences are most evident between ex-Model C schools and historically disadvantaged ex-DET schools, and it is recognised that principals in ex-DET schools need support tailored to their particular circumstances and context. The findings in this study support the notion that much needs to be done in South Africa in terms of empowering school principals; especially those from historically disadvantaged schools. The data provide insights into some of the constraints of local context, which enables better understandings of the challenges of instructional leadership in historically disadvantaged schools. These understandings should be of value when considering strategies to support principals in their role of instructional leaders.

- Description: In view of the important role small and medium-sized enterprises (SMEs) universally play as the backbone of national economies and the survival and competitiveness challenges that they face, the purpose of this study was to develop specific models of corporate social responsibility (CSR) for SMEs in Uganda as an avenue to enhance their competitiveness and foster economic development. The primary objective was to gain insight into the deployment of CSR in SMEs, including investigating CSR factors and their potential impact on competitiveness. This study integrates previous findings and theories on CSR activities and SMEs‟ competitiveness into a comprehensive hypothesised model. A comprehensive literature study revealed potential factors that could influence the Increased competitiveness of SMEs in Uganda. Four independent variables (Workforce-oriented, Society-oriented, Market-oriented and Environmental-oriented CSR activities) and three mediating variables (Employee satisfaction, Business reputation and Customer loyalty) were identified as variables influencing the Increased competitiveness (dependent variable) of SMEs. Independent variables were categorised as CSR factors while mediating and dependent variables were categorised as outcomes factors. Furthermore, hypotheses were formulated for possible relationships between the independent, mediating and dependent variables. All the variables in the study were clearly defined and operationalised. Reliable and valid items sourced from various measuring instruments used in other similar studies, were used in the operationalisation of these variables. Furthermore, several items were generated from secondary sources. A structured self-administered questionnaire was made available to respondents identified using the stratified and purposive sampling techniques, and the data collected from 383 usable questionnaires was subjected to several statistical analyses. The validity and reliability of the measuring instrument was ascertained using an exploratory factor analysis and Cronbach-alpha coefficients respectively. An exploratory factor analysis using SPSS 18 for Windows was conducted to identify the unique factors available in the data before applying structural equation modelling (SEM). The data were categorised into models of independent variables (CSR factors) and the mediating variables (Outcomes factors). The items measuring Market-oriented CSR activities and Workforce-oriented CSR activities loaded as expected. The items measuring Environmental-oriented CSR activities loaded onto two separate factors which were renamed Environmental-oriented CSR activities and Regulated CSR activities. One of the items originally expected to measure the construct Society-oriented CSR activities loaded onto Environmental-oriented CSR activities, leaving three items which loaded together onto the Society-oriented CSR activities factor. Four factors constituted the outcomes submodel, namely Customer loyalty, Stakeholder trust, Business reputation, and Employee satisfaction. In this study, SEM was the main statistical procedure used to test the significance of the relationships hypothesised between the various independent and dependent variables. Owing to the sample size limitations, the hypothesised model could not be subjected to SEM as a whole. Consequently, six sub-models were identified and subjected to further analysis. The following independent variables were identified as influencing the dependent variables in this study: Workforce-oriented CSR activities, Society-oriented CSR activities, Market-oriented CSR activities, Environmental-oriented CSR activities, Regulated CSR activities. To establish the influence of the various demographic variables on the mediating and dependent variables, an Analysis of Variance (ANOVA) and Multiple Linear Regression (MLR) analysis were conducted. The respondent‟s position/title in the business, form of enterprise, branch/sector of business, level of education, and the size of business were found to have an influence on the mediating and dependent variables of this study. This study has therefore added to the underdeveloped body of business research in Uganda by investigating a particularly limited segment of the literature, namely SMEs. The study has also identified and developed various models that explain the most significant CSR factors that influence the competitiveness of SMEs. Consequently, this study has put forward several recommendations and suggestions that can enhance the competitiveness of SMEs locally and globally. Further research is encouraged on action-oriented areas such as: the success of different policies and techniques to increase the uptake of CSR amongst SMEs; the economic, social and environmental impact of CSR at sector level; and a typology of SMEs with regard to their engagement in CSR.

The data were categorised into models of independent variables (CSR factors) and the mediating variables (Outcomes factors). The items measuring Market-oriented CSR activities and Workforce-oriented CSR activities loaded as expected. The items measuring Environmental-oriented CSR activities loaded onto two separate factors which were renamed Environmental-oriented CSR activities and Regulated CSR activities. One of the items originally expected to measure the construct Society-oriented CSR activities loaded onto Environmental-oriented CSR activities, leaving three items which loaded together onto the Society-oriented CSR activities factor. Four factors constituted the outcomes submodel, namely Customer loyalty, Stakeholder trust, Business reputation, and Employee satisfaction. In this study, SEM was the main statistical procedure used to test the significance of the relationships hypothesised between the various independent and dependent variables. Owing to the sample size limitations, the hypothesised model could not be subjected to SEM as a whole. Consequently, six sub-models were identified and subjected to further analysis. The following independent variables were identified as influencing the dependent variables in this study: Workforce-oriented CSR activities, Society-oriented CSR activities, Market-oriented CSR activities, Environmental-oriented CSR activities, Regulated CSR activities. To establish the influence of the various demographic variables on the mediating and dependent variables, an Analysis of Variance (ANOVA) and Multiple Linear Regression (MLR) analysis were conducted. The respondent‟s position/title in the business, form of enterprise, branch/sector of business, level of education, and the size of business were found to have an influence on the mediating and dependent variables of this study. This study has therefore added to the underdeveloped body of business research in Uganda by investigating a particularly limited segment of the literature, namely SMEs. The study has also identified and developed various models that explain the most significant CSR factors that influence the competitiveness of SMEs. Consequently, this study has put forward several recommendations and suggestions that can enhance the competitiveness of SMEs locally and globally. Further research is encouraged on action-oriented areas such as: the success of different policies and techniques to increase the uptake of CSR amongst SMEs; the economic, social and environmental impact of CSR at sector level; and a typology of SMEs with regard to their engagement in CSR.

- Description: This study examined the existing levels of effectiveness and efficiency in local government with the application of performance management systems in the provision of municipal services. The provision of district-wide water services in Cacadu District Municipality in the Province of the Eastern Cape, South Africa is used for particular reference. Local government reforms after 1994 led to the creation of the district municipality (which groups together a number of local municipalities) to drive district-wide services provision, the introduction of systematic services provision standards and performance management as part of management reforms in municipalities. The problem for the research deals with how the Cacadu District Council and the councils of the local municipalities within the district are collaborating in using performance management systems, what effects this could have on programmes and services provision and how communication of performance information would improve service provision. Conceptual and practical difficulties encountered in effective and efficient utilisation and some obstacles that contribute to impeding progress in the use of performance management systems in municipalities were analysed. The qualitative research included a review of documents from the public administration and management literature; discourse analysis of interviews with municipal councilors and appointed officials, community members and provincial managers. The document review included a review of municipal documents that incorporated performance management or described development and use of performance management systems. It also included the legal frameworks and statutory requirements for municipal government and administration. All the responding municipal councils within the Cacadu District Municipality reported using performance management over the past five years yet little empirical evidence explains usage for district-wide programmes and services provision. Research shows that a comprehensive performance management approach to programmes and services has a more effective and efficient impact on service improvement than utilisation of personnnel appraisal (Ammons and Rivenbark, 2005). Despite the expected benefits, personnel performance appraisal is often flawed and the need exists in the district municipal model to develop and utilise performance management systems that validly assess the work performance of personnel (Hindo, 2010). Performance management system utilisation in decision making management is more related to the long-term benefits of effectiveness and efficiency than personnel appraisal for performance rewards and reporting. To overcome and address a situation of managing performance without a performance management system the study proposes a programme performance measurement and management system which incorporates information on management inputs, programme-specific data and citizens' feedback for outcomes and impact of the service. The suggested design for district-wide and specific municipal services provision elicit and provide relevant and appropriate performance information for management, decision-making and accountability to community. The effectiveness of the proposed system is to provide information for decision-making, long-term planning, strategic management and accountability reporting. The proposal is built on the exisiting method and thus efficient in the utilisation of resources. This has implications both for the theory of Public Administration and Management and the practical application of performamce management in public institutions. The study explicity provides a Public Administration perspective on management in a multi-municipal district context with different authorities. The study contributes to the theory of administrative policy and management context of the municipality with special attention to functions for which different authorities are responsible and the role of a performance system for better insught into managing overlapping authority, gaps and duplications. A central purpose of public management research is to theorise and influence practice. The practical utilisation of the proposed method is intended to assist managers and politicians with better understanding of a sustainable performance management system.

- Description: The primary objective of this thesis is to account for the fertility decline among Abagusii women in South-western Kenya. The motivation behind the study was based on the fact that the fertility trends associated with this group of people had not been studied before. This is surprising because the Abagusii recorded one of the world's highest total fertility rates of 10.4 in 1979 (Omosa 1994; Osiemo 1986; Oucho 1990), but has also experienced significant fertility decline. The total fertility rate in 2004 stood at 4.7, (Anyara 2009). The analytical framework that is adopted is Stover's (1998) adaptation of the Bongaarts et. al. (1984) Proximate Determinants Model. These determinants such as contraceptive use, post-partum insusceptibility, sexual activity, abortion and sterility represent behavioural and biological variables that affect fertility directly. The manner in which they are employed involves using the index which indicates the extent to which each proximate determinant reduces the fertility of the group in question.

- Description: Games as a form of communication have been examined by academics in the fields of game studies, narratology and media studies, among others, but the use of games to communicate advertising messages has not been adequately explored within the South African context. The study sought to investigate the phenomenon of advergaming, purpose-built games designed to communicate an advertising message, in South Africa, and to develop a model for the use of advergaming as a viral marketing tool in this context. Using a hybrid approach, the study examined the way that advertising agencies currently use advergames as well as the effectiveness of advergaming as a means to communicate a message. The study presents the results of a national survey of advertising agencies in South Africa, a content analysis of existing advergames and an analysis of three semi-structured group interview experiments conducted using selected advergames. The findings point to the potential of advergaming as a message communication tool, but also highlight the challenges that may hamper the widespread use of advergaming in South Africa. It proposes the use of the mobile environment as a means to reach a wider South African audience and in that way, overcome some of the obstacles to advergaming adoption. In addition, the results identify aspects of advergames that seem to correlate with the effectiveness of message communication.

- Description: Electrospinning is a technique, which can be used to produce nanofibrous materials by introducing electrostatic fields into the polymer solution. Due to their intrinsic properties, such as small fiber diameter, small pore size and large surface area, nanofibres are suitable for use in a variety of applications including wound dressing, filtration, composites and tissue engineering. The study demonstrates the successful and optimised production of Poly(ethylene oxide) (PEO) and chitosan nanofibres by electrospinning. The biocidal effects of chitosan, chitosan-silver nanofibres and silver nanoparticles were successfully investigated. To set up a functional electrospinning apparatus, the PEO solution parameters (concentration, molecular weight, solvent, and addition of polyelectrolyte) and applied potential voltage on the structural morphology and diameter of PEO nanofibres were studied. At lower PEO concentrations, the fibres had morphology with a large variation in fibre diameter, whereas at the higher concentrations, the nanofibres exhibited ordinary morphology with uniform but larger fibre diameters. Higher molecular weight showed larger average diameters when compared to that obtained with the same polymer but of a lower molecular weight. The addition of polyelectrolyte to the polymer solution had an influence on the structural morphology of the PEO. Flow simulation studies of an electrically charged polymer solution showed that an increase in the flow rate was associated with an increase in poly(allylamine hydrochloride) (PAH) concentration for the low molecular weight polymer, the shape and size of the Taylor cone increasing with an increase in PAH concentration for the low molecular weight polymer. During optimization of the PEO nanofibres, based on statistical modelling and using the Box and Behnken factorial design, the interaction effect between PAH concentration and the tip-to-collector distance played the most significant role in obtaining uniform diameter of nanofibres, followed by the interaction between the tip-to-collector distance and the applied voltage and lastly by the applied voltage. The production and optimization of chitosan nanofibres indicated that the interactions between electric field strength and the ratio of trifluoroacetic acid (TFA) and dichloromethane (DCM), TFA/DCM solvents as well as between electric field strength and chitosan concentration had the most significant effect, followed by the concentration of chitosan in terms of producing nanofibres with uniform diameters. Chitosan and chitosan-silver nanofibres could be successfully electrospun by controlling the solution properties, such as surface tension and electrical conductivity with the silver nanoparticles in the chitosan solutions affecting the electrospinnability. The silver nanoparticles in the chitosan solution modified the morphological characteristics of the electrospun nanofibres, while the conductivity and the surface tension were elevated. The fibre diameter of the chitosan and chitosan-silver nanoparticles decreased with an increase in the silver content. The electrospun chitosan nanofibres had a smooth surface and round shape as compared to the silver-chitosan nanofibres with a distorted morphology. The chitosan and chitosan-silver nanofibres as well as the silver nanoparticles exhibited antimicrobial or inhibition activity against S. aureus than against E. coli. S. aureus bacterial culture showed good cell adhesion and spreading inwards into the chitosan nanofibrous membrane. The chitosan-silver nanofibres exhibited a greater minimum inhibitory concentration (MIC), followed by silver nanoparticles and then chitosan nanofibres; suggesting a synergistic effect between the chitosan and silver nanoparticles.

- Description: Up to 2005 early childhood education in Zimbabwe was organised, directed and run by non-governmental organisations, churches and private individuals. Such an arrangement meant that the curriculum, personnel and strategies used to implement the programme were varied. In 2004 the Ministry of Education directed that all primary schools attach two classes of children aged between 3 and 5 years with effect from 2006, thus effectively making early childhood education part of the formal primary school structure. The research presented in this thesis focuses on teachers' perceptions of primary schools' state of readiness for the introduction of early childhood education in Zimbabwe. Located in the interpretive paradigm of qualitative research the study draws on a wide range of research methods. In particular a multiple case study was used to explore teachers' perceptions of primary schools' state of readiness for the introduction of grade zero/early childhood education in a former government group B school, a church run school, a rural school, a former government group A school and, a council run school. Some of the key findings of the study are: • School heads who are the principal gate keepers in primary schools were not provided with any preparation for the introduction of grade zero/early childhood education. • School reliance on fees and levies, without direct Ministry of Education financial assistance, meant that resource conditions - hence state of readiness - greatly differed from one school to another. • No ongoing support was provided to school heads, teachers-in-charge and early childhood education teachers. • The quality of teaching and learning at the early childhood education level, in the multiple case study, depended on the nature of teacher preparation, availability of appropriate resources, adequacy and appropriateness of teacher support, and teacher state of preparedness. The study recommends interventions that curriculum policy planners and implementers can use to create conditions that enable schools to be ready for installing, implementing and institutionalising the early childhood education innovation.

- Description: Much emphasis has been placed on democracy, equality and human rights since the dawn of the democratic South Africa in 1994. Efforts to align the South African education system with the democratic principles of the Constitution, not only in terms of eradicating past racial divides, but also in terms of accessibility to learners who experience barriers to learning are eminent. The South African Government issued various policies to ensure quality, equitable and accessible education for all, irrespective of ability. Theoretically, no learner should therefore being discriminated against on any basis. In practice, however, thousands of learners, especially those who experience barriers to learning are denied the opportunity to receive meaningful development opportunities in many mainstream primary schools, resulting in their early drop out from school without having acquired the basic skills and knowledge to become self sustainable members of their communities. With the adoption of Bronfenbrenner’s ecological model as theoretical framework for this study, the primary aim of this qualitative investigation was to investigate and describe how effective learners who experience barriers to learning are managed in mainstream primary schools and to develop a framework for the creation of more sustainable management systems to ensure that the needs of all learners are met. The findings of the empirical investigation revealed that most learners who experience barriers to learning are currently not managed effectively in mainstream primary schools due to factors situated across the whole education system, to the detriment of learners who experience barriers to learning. Based on the findings of the empirical investigation, this study proposes a framework which will ensure the effective management of learners who experience barriers to learning in mainstream primary schools. The framework include recommendations to be implemented across all layers of the ecological system.

- Description: The human immunodeficiency virus / acquired immune deficiency syndrome pandemic (HIV/AIDS) continues to increase in prevalence worldwide, particularly in South Africa. There is a concurrent and distinct increase in the prevalence of HIV/AIDS and HIV-related diseases in the paediatric population in South Africa, particularly those using public sector health services, with a corresponding increase in morbidity and mortality rates (Abdool Karim & Abdool Karim, 2010:363), which impacts greatly on paediatric healthcare services. Adding to this, the provision of paediatric antiretroviral care has numerous stumbling blocks, not least of which is lack of decentralisation of facilities to provide treatment. There is the additional shortage of staff, which includes staff that are comfortable dealing with children, lack of training programmes on the provision of antiretroviral therapy to children, and minimal on-site mentorship of staff regarding HIV/AIDS disease in children. This lack of capacity in the healthcare system means that not all of those who require treatment will be able to access it, and this is particularly pertinent to paediatric patients (Meyers et al., 2007:198). Therefore the purpose of this research was to develop a nursing model that would assist healthcare professionals, in particular professional nurses, to optimise the comprehensive treatment, care and support for HIV-positive children who require antiretroviral therapy at PHC clinics. To achieve the purpose of this study, a theory-generating design based on a qualitative, explorative, descriptive and contextual approach was implemented by the researcher to gain an understanding of how the healthcare professionals and parents/caregivers of HIV-positive children experienced the comprehensive treatment, care and support provided at primary healthcare clinics. The information obtained was used to develop a chronic care coordination model for the optimisation of comprehensive treatment, care and support for HIV-positive children requiring antiretroviral therapy. The study design comprised the following four steps: Step One of the research design focused on the identification, classification and definition of the major concepts of the study. This involved describing and selecting the research population and the sampling process prior to conducting the field work which comprised in-depth interviews with two groups of participants, namely healthcare professionals and parents/caregivers who accompany their HIV-positive children to PHC clinics in order to receive antiretroviral therapy. Step Two of the research design focused on the development of relationship statements in order to bring clarity and direction to the understanding of the phenomenon of interest. Step Three of the design concentrated on the development and description of the chronic care coordination model for optimising comprehensive treatment, care and support for HIV-positive children who require antiretroviral therapy in order to ensure a well-managed child on ART. A visual representation of the structure of the model for chronic care coordination was given and described as well as a detailed description of the process of the model. Step Four was the last step of the research design and its focus was the development of guidelines for the operationalisation of the model for chronic care coordination for the optimisation of comprehensive treatment, care and support for HIV-positive children requiring antiretroviral therapy at PHC clinics. Guidelines and operational implications for each of the five sequential steps of the model were developed. The evaluation criteria of Chinn & Kramer (2008:237‒248) were used to evaluate the model. It is therefore concluded that the researcher succeeded in achieving the purpose for this study because a chronic care coordination model that is understandable, clear, simple, applicable and significant to nursing practice has been developed for use by healthcare professionals, particularly professional nurses, in order to optimise the comprehensive treatment, care and support for HIV-positive children requiring antiretroviral therapy at primary healthcare clinics.

- Description: The human immunodeficiency virus / acquired immune deficiency syndrome pandemic (HIV/AIDS) continues to increase in prevalence worldwide, particularly in South Africa. There is a concurrent and distinct increase in the prevalence of HIV/AIDS and HIV-related diseases in the paediatric population in South Africa, particularly those using public sector health services, with a corresponding increase in morbidity and mortality rates (Abdool Karim & Abdool Karim, 2010:363), which impacts greatly on paediatric healthcare services. Adding to this, the provision of paediatric antiretroviral care has numerous stumbling blocks, not least of which is lack of decentralisation of facilities to provide treatment. There is the additional shortage of staff, which includes staff that are comfortable dealing with children, lack of training programmes on the provision of antiretroviral therapy to children, and minimal on-site mentorship of staff regarding HIV/AIDS disease in children. This lack of capacity in the healthcare system means that not all of those who require treatment will be able to access it, and this is particularly pertinent to paediatric patients (Meyers et al., 2007:198). Therefore the purpose of this research was to develop a nursing model that would assist healthcare professionals, in particular professional nurses, to optimise the comprehensive treatment, care and support for HIV-positive children who require antiretroviral therapy at PHC clinics. To achieve the purpose of this study, a theory-generating design based on a qualitative, explorative, descriptive and contextual approach was implemented by the researcher to gain an understanding of how the healthcare professionals and parents/caregivers of HIV-positive children experienced the comprehensive treatment, care and support provided at primary healthcare clinics. The information obtained was used to develop a chronic care coordination model for the optimisation of comprehensive treatment, care and support for HIV-positive children requiring antiretroviral therapy. The study design comprised the following four steps: Step One of the research design focused on the identification, classification and definition of the major concepts of the study.

- Description: Citizens interact with government departments and agencies for public services and goods which lead to a service encounter between a public official and client. Various initiatives and policies have been developed and are being implemented in the public service to adopt a client-centred approach to service delivery. The White Paper on the Transformation of the Public Service of 1997, identifies the eight Batho Pele principles which sets the framework for implementation of service quality within the South African public service. Government departments are expected to implement measurable service standards to determine levels of service quality to be met that will define levels of client satisfaction with service provision. The assessment of the service encounter by the client informs perceived levels of satisfaction held. This assessment of service quality by clients is therefore value-laden, subjective and periodic. The study focused on the implementation of measures to create and maintain a clientcentric public service in South Africa that would lead to levels of client satisfaction with service quality. The study assessed the implementation and maintenance of service quality at the Social Security Agency of South African the Eastern Cape. The SASSA is responsible for the disbursement of various social grants to facilitate a quality of life as enshrined by the Bill of Rights in the Constitution of South Africa, 1996. The focus of the study was linked to beneficiary maintenance and customer care at SASSA. The study included three different sample groups namely the clients, officials engaged in grant administration and different levels of management which included senior management, district and area managers. The findings revealed that the SASSA has implemented numerous new programmes aimed at a client-centric approach to service delivery. Analysis of the findings revealed expectation as well performance gaps which indicated that officials do not comply with the protocols of the agency and the Batho Pele principles. The promised service standards specified within the SASSA Customer Care Charter is not being realised which fundamentally indicate inefficient and ineffective monitoring of compliance with norms and standards. A conclusion drawn therefore is that the human dignity of clients in search of socials assistance who chiefly constitute vulnerable groups is being infringed. Three key service quality dimensions are identified that needs intervention for improved service quality. These dimensions include tangibility, assurance and responsiveness of functional components identified in respect of nine themes.

- Description: Census estimates in 2010 indicated that 6,3 percent South Africans aged 5 years and older are currently classified as disabled in five of the nine provinces in the country. The national figure for 2005 was 5 percent, with the figure for females (6,5 percent) slightly higher than that for males (6,1percent). Spinal cord injured persons and their significant others experience a range of emotions which affect their relationships with themselves, others and their environment. To deal with the life-changing consequences of the injury and regain control, these persons not only require a variety of coping strategies but rediscovery of resilience is inevitable if the experience of personal purpose and meaningful existence is ever to be regained. In the Nelson Mandela Bay Municipal area, Port Elizabeth, South Africa – the geographical area in which this research study was undertaken - persons with spinal cord injuries have many challenges to face due to the shortcomings the existing resource for health care delivery in the post-discharge phase. The research objectives identified for the study were, firstly, to explore and describe the lived experiences of persons with spinal cord injuries; secondly, to explore and describe the lived experiences of the significant others of persons with spinal cord injuries; and thirdly, to develop a strategy to guide the professional nurse and the health care team in facilitating the health care of persons with spinal cord injuries. The study was a qualitative, exploratory, descriptive, and contextual method of inquiry. The data obtained was used to formulate the strategy with its three sub-strategies to guide professional nurses and the health care team to facilitate renewed resilience and the re-establishment of meaning for persons with spinal cord injuries. Although the experiences of the significant others were explored in order to thicken the description of the experiences of persons with spinal cord injuries, the strategy developed was limited to the persons with spinal cord injuries. Although it is well documented that there are significant physical needs, the themes that emerged from the current research mostly related to psychological and social aspects. In acknowledging the human being as unitary multi-dimensional being, the researcher in his discussions and quest to address the issue of renewed resilience in spinal cord injured persons towards finding purpose and re-establishing meaning in their lives, focused on their psychological, spiritual and social health. The outcome of the study is a strategy constructed to facilitate renewed resilience, and three sub-strategies ‘addressing experienced emotions’, ‘facilitating meaningful relationships’ and ‘facilitating effective coping’. The strategy has as purpose the empowering of spinal injured persons in their efforts to re-establish meaning by serving as a tool to guide professional nurses and members of the health care team in their facilitating of renewed resilience in persons with spinal cord injury. It is envisaged that the co-ordination of the strategy will take place from the health care delivery facility nearest to the spinal cord injured individual concerned. In order for persons with spinal cord injuries to become accountable members of society, all levels and aspects of care aimed at physical, psychological, spiritual and social well-being need to be holistically addressed. The front-line role of the professional nurse is vital as the professional nurse acts as the co-ordinator for the health care team in ensuring that persons with spinal cord injuries receive quality and holistic care in order to deal meaningfully with the life-altering consequences of a spinal cord injury. Through this study, valuable insight was gained with regard to experiences of both persons with spinal cord injuries and that of their significant others. Recommendations were made for nursing practice, nursing education and nursing research.

- Description: This study is an interpretive analysis of the roles of NGOs in the social policy process, using the case of postcolonial Zimbabwe. Assessing the period between 2000 and 2010 and the prevailing unique socio-economic and geopolitical crisis, the study engages the major contextual factors influencing evolution of NGOs and their engagement in the policy process. It focuses on the conceptual and state – civil society contestations on the legitimacy of NGO’s as well as an assessment of their impact on the social policy process. NGOs in Zimbabwe have played two major and two minor roles in the social policy process as identified in the study in terms of their prominence and impact on the policy process. That is: policy implementer role complementing state social policy provision, democratisation to pluralism the social policy arena as the major roles; educational role to developing interventions for better social policy and watchdog role monitoring government and other state institutions in meeting the social policy needs of citizens. The thesis argues that analysis of NGOs is embedded in understanding the role of the state and dialectical relationship between state and civil society. Using a neo-Marxist perspective and social democratic approach to the role of the state in social policy, the theoretical generalisations of the study are that NGOs have a legitimate role to play in the social policy process. However, this is defined by the nature and role of the state itself as central driving agent in social policy. Therefore, the roles NGOs are not exclusive in themselves but are anchored within the contextual framework and its definition of societal spheres within it. The thesis established the evolution of the NGO sector in Zimbabwe, its impact on the social, political landscape and argues that the democratisation agenda in Zimbabwe requires a political solution embedded in a transformative state as the panacea for building a redistributive and participatory social policy agenda that engages with non-state actors, NGOs included within a developmental framework. Conclusively, the thesis proposes a theoretical distinction between NGOs as service oriented entities and CSOs as forums for associational life and civic engagement.

- Description: The success of the larval stage in fishes plays a critical role in structuring adult fish populations. It is well understood that juveniles of many marine fish species are closely associated with nearshore and coastal habitats that serve as nursery areas while adult assemblages are more widely distributed. The larval phase however, particularly pertaining to nursery habitat use, remains poorly understood in South Africa. A mixed-method, larval and juvenile fish study was conducted in the warm-temperate shallow coastal waters of Algoa Bay, South Africa. Two years (2010 – 2012) of seasonal sampling at 27 stations at various habitat types revealed distinct spatio-temporal patterns in larval fish composition and abundance. In total, 164 species from 50 families were collected in the nearshore (<30 m), over reef and sand, in the surf zone and large estuarine habitats in Algoa Bay. Engraulidae dominated the larval fish catch in the nearshore (38.4 percent) and over the selected reef and sand habitats (37.8 percent). Cynoglossidae (28.1 percent) and Sparidae (8.4 percent) were the second and third most abundant fish families in the nearshore. In subtidal reef and sand habitats, Gobiidae (23.4 percent) and Clupeidae (9.2 percent) were the second and third most abundant families respectively. Sparidae dominated (71.4 percent) surf zones followed by Soleidae (10.8 percent) and Mugilidae (5.3 percent), while in the mouth area of two permanently open estuaries in Algoa Bay, Gobiidae (35.9 percent) Sparidae (30.1 percent) and Mugilidae (12.4 percent) dominated. Several species from the Blenniidae, Gobiesocidae, Gobiidae, Scorpaenidae and Tripterygiidae fish families complete their pelagic larval phase in the reef habitats in Algoa Bay. These reef habitats therefore serve as important nursery areas for the larvae of benthic species. The sand and nearshore habitats serve as nursery areas for Clupeidae and Engraulidae. Highest densities of Carangidae, Sciaenidae and Sparidae larvae were observed at the subtidal reef habitats indicating that this area is important for accumulation of the early developmental stages of these fishes. The nearshore serves as an important accumulation habitat for species in the Haemulidae and Soleidae families whose juveniles are known to recruit into estuarine nursery areas. The nearshore therefore is a specific area of presettlement buildup of larvae prior to settlement of larvae or juveniles in estuarine nursery areas. Cynoglossidae larvae are also using the nearshore as an accumulation area prior to settlement and recruitment into adult populations occurring in shallow water habitats. In the surf zone, not only are estuary-dependent fish species utilizing this habitat as a nursery area, but marinespecies whose adults are either associated with rocky shores or surf zones are similarly using these areas as nursery habitats. In addition, estuary-dependent fish species which spawn in the marine environment are actively recruiting into estuarine nursery areas on both tides. Active recruitment against the outgoing ebb tide flow was a conclusive finding in this study. These larvae and juveniles are actively swimming against the ebb tide in the shallower, slower-flowing marginal areas where current flow is reduced. Strong environmental gradients on multiple temporal and spatial scales occur in Algoa Bay. Seasonal patterns were evident in larval densities, richness and diversity. Peaks in density, richness and diversity occurred during spring and summer (September to February) associated with increasing water temperatures and a high productivity providing a good food environment for larval fishes. Thereafter densities declined steadily as a result of natural mortality, settlement or adult spawning activity, until autumn when numbers dropped suddenly as the surviving larvae moved to settlement habitats. The relationship between larval fish and environmental variables provides information useful to determine distributions. Therefore the Bay is particularly suited for modelling larval fish distributions. Using generalized linear models, larval fish density in the nearshore of Algoa Bay responded to different ocean features to varying degrees. Larval fish density responded positively to both upwelling and when warm water plumes, originating from an Agulhas Current meander, entered Algoa Bay. On subtidal reefs, habitat complexity played an important role in determining larval fish composition and diversity. The less structurally complex, reefassociated sand habitats, yielded higher species richness and diversity than the high and low profile reef habitats. Therefore, it is likely that the importance of less structurally complex habitats has been overlooked relative to other habitats in terms of their function for larval fishes. In the surf zone, wave period and wave height, which can be related to exposure, were the most significant environmental factors influencing larval fish assemblages. Greatest species diversity was observed in the surf zone habitats heavily influenced by wave action in the windward sector of Algoa Bay. The identification of spawning areas and the mapping of distributions of early developmental stages of fishes are important in providing data pertaining to the protection of these habitats. This is particularly relevant as a new marine protected area MPA)is planned for the eastern sector of Algoa Bay. Results from retrogressive plots indicate that the spawning locations of several species of coastal and pelagic fishes are occurring outside of the Bay, with the bay therefore serving as an accumulation area. Furthermore, distribution modelling results demonstrate that the early developmental stages of fishes in the shallow coastal habitats of Algoa Bay exhibit high spatial variability in their distributions. Results presented in this thesis help fill the knowledge gaps critical to the understanding of larval fish nursery areas of several economically and ecologically important fish species in Algoa Bay.

- Description: Project management is undeniably the fastest growing discipline as organizations move into the euphoria of projectification of their operations. Though projects have been a part of human life since time immemorial, there is a sudden realisation of the effectiveness of the methods used in project management. The enrolment of students studying for project management in tertiary institutions has shown tremendous increase. Yet the project execution process is mired by high failure rates and absence of clarity on the necessary skills required for effective project execution. The authority-gap in project management presents political and operational conflicts, and new innovative ways of authority-gap reduction need to be identified and taught in training programs. Simultaneously there is a realisation by both academics and practitioners that there is a difference between managers and leaders. Extensive studies on leadership have not allowed for a one-stop-leadership-style to be used in leadership of any form, let alone project leadership. In fact there is no standard definition of leadership as this has been heavily contextualized and thereby disallowing the creation of a universal definition. No cast-in-stone leadership styles are known and thereby leaving the research on leadership to concentrate on critical competencies required for effective leadership of projects. This study seeks to establish the core competencies needed by the project leaders and other practitioners to reduce the failure rate and maximise the benefits currently sought after by organisations. Studies have shown that the matrix structure within which the embedded projects work is a contributing factor to the failure of projects. Because projects are executed by people, it would be the proper utilisation of people’s talents and competencies that are expected to yield favourable results. Thus, whilst the matrix structure creates the authority-gap that presents a problem for effective project execution, management-by-projects still remains the best way known to add economic value to performance and productivity. The study therefore focuses on those characteristics of project leaders that will most likely make the difference in the way people perform in the workplace. The research findings emphasised the importance of empowerment of project managers and the development of their interpersonal skills of the project leader with special emphasis on extroversion, genuineness of senior management, and the responsiveness of the project leaders as important requirements for effective authority- gap reduction. These critical competencies will therefore facilitate the project execution process and enhance the empowered project leader’s ability to reduce the high project failure rate and high cost overruns. These competencies apply specifically to the human element as it relates to the role of the project leader and the interaction with the team members, this new knowledge needs to be introduced into training programs and project practitioners.

- Description: The remnant life monitoring of creep loaded high temperature and pressure components in power stations is critical to ensuring their safe and cost effective operation as failures can have severe consequences. Effective creep life condition monitoring allows for optimising component life predictions and subsequent plant maintenance decisions. In South Africa many power generation stations have been in operation well beyond their 30 year design service life, as such knowledge of the remnant creep life of high temperature and pressure components, such as steam pipelines, becomes of utmost importance. Techniques for the remnant creep life assessments of critical high temperature and pressure components must therefore be as effective as possible. The common and well accepted in-situ inspection technique for assessing creep damage in steam pipes is by the metallographic replication technique. The technique is however limited to the outer surface of the pipe, without information on damage within the wall. This research will illustrate a means of obtaining a sample for creep life analysis with depth through the wall of a pipe, as wells as an alternative technique for the repair of the sample retrieval site. A sample retrieval technique was developed that would retrieve a small diameter cylindrical sample from a cored blind hole for creep analysis by visual creep void assessment or by the small punch creep test. The small punch creep test requires only a small diameter thin disc of material for testing for which its results are comparable with conventional uniaxial creep testing which requires a much larger sample of material. The smaller sample requirement of the small punch creep test therefore allows for a vastly reduced invasive sample retrieval operation and consequently smaller repair size area. Also the fact that the sample is retrieved from a blind hole is advantageous since the pipe wall is not penetrated which would require full plant shutdown. A friction welding technique was identified as an alternative to traditional arc fusion welding for the repair of the sample retrieval site, this technique being the Friction Hydro Pillar Processing technique. Friction Hydro Pillar Processing is a solid-state welding technique and as such has a number of inherent benefits over arc fusion welding as the weld is performed below the melting temperature of the material. From a process point of view Friction Hydro Pillar Processing is ideally suited for automation, has virtually no fumes generated, minimal distortion is experienced and no spatter has to be removed afterwards. The technique has yet to see industrial application and as such development of suitable process parameters was undertaken. Finally, to apply the sample retrieval and repair operations in-situ to a steam pipe in a power plant suitable equipment was developed. Existing friction welding equipment is generally bulky workshop based equipment and is unsuitable for on-site work due to its size and weight. Therefore development of dedicated equipment was required to enable Friction Hydro Pillar Processing to be applied to steam pipes within a power plant environment.

- Description: The purpose of this study was to develop and empirically test a hypothetical model of factors impacting performance of training institutions in Uganda in order to establish their statistical significance. The liberalisation of the education sector in Uganda, which has led to the rapid growth in the establishment of private sector higher education institutions in the country, now necessitates empirical and theoretical research into the factors impacting performance of these training institutions. The mission of higher education training institutions is to constantly create a critical academic community to debate national issues and to generate relevant knowledge for the country’s economic growth and development. The study investigated and analysed how the independent variables (individual-, institutional- and external) impact institutional performance (dependent variable). The study reviewed literature in the areas of individual-, institutional- and external factors supported by Wei’s (2006), Mackenzie-Phillips (2008), Burke-Litwin (1994), Lusthaus, Adrien, Anderson and Carden (1999) and The Jain (2005) models as presented in section 6 of chapter one. The hypothetical model developed was based on the models mentioned. The study sought the perceptions of managers and utilised the quantitative research paradigm. A survey was conducted using a self-administered questionnaire distributed to managers in both public and private training institutions in Uganda. The final sample comprised 488 respondents. Data was collected in 2012 over a period of four months. The returned questionnaires were subjected to several statistical analyses. The validity of the measuring instrument was ascertained using exploratory factor analysis. The Cronbach’s alpha values for reliability were calculated for each of the factors identified during the exploratory factor analysis. In this study, correlation and exploratory factor analysis, the KMO measure of sample adequacy and Bartlett’s test of sphericity and regressions were the main statistical procedures used to test the appropriateness of data, correlation and significance of the relationships hypothesised between the various independent and dependent variables. The study identified nine independent variables as significantly impacting the performance (dependent variable) of training institutions in Uganda. Three statistical significant relationships were found between the individual factors: knowledge acquisition, role identity, employee empowerment and performance of training institutions in Uganda. Four statistical significant relationships were found between the institutional factors: strategic intent, management capabilities, organisational resources, organisational culture and performance of training institutions in Uganda. Two statistical significant relationships were found between the external factors: political/legal, stakeholders and performance of training institutions in Uganda. The study also found five statistically insignificant variables. It was found that managers in training institutions in Uganda should encourage employees to assess their own performance. Managers should formulate a policy on transparency and practice open communication using the right communication channels. Training institutions in Uganda should consider having organic and flatter organisational structures with a wider span of control. Managers should regard economic variables such as inflation rates and tax obligations when planning and drawing up budgets as this will impact their profitability. There is a need in Uganda to collaborate with and forge close relationships with international training institutions and global partners to become more globally competitive. The study has provided general guidelines at individual level how to best utilize employees to improve performance of training institutions in Uganda. Furthermore, general operational guidelines at institutional level for improving performance of training institutions have been given for such institutions to become and remain competitive in the global market place. The study has also highlighted general guidelines regarding managing external environmental factors to assist in improving performance of training institutions in Uganda.

- Description: To make education a profitable enterprise and contributor to social development requires that schools infuse values into schooling as part of the ethical construction of learners and citizenship building. This research used Kampala district as the case study to conduct a qualitative inquiry with grounded theory to examine the integration of values into the management of learners’ discipline in Ugandan schools. Using a sample of 60 participants, the researcher gathered data using personal interviews, focus group interviews, and documentary analysis. Through the analysis of this data, the researcher established that the School Governing Body (SGB), government, educators, missionaries and the community are stakeholders highly involved in directing the process of values integration into learners’ discipline. He also discerned that different schools impart moral, spiritual, academic, aesthetic, social and universal values into the learners. However with the 1963 Castle Report on Education that led to the nationalization and secularization of schools, denominational schools strongly felt that government robbed them of their powers to control and manage schools through the “principle of subsidiarity”. This seems to have led to the gradual erosion of values and breakdown of discipline in the denominational schools as well as the others. The central argument of this thesis is that integrating values into school discipline in Uganda would result into an inclusive education system that supports both theist and atheist attitudes towards formal schooling. Some respondents argued that values should be directly integrated into learners’ discipline while others opposed values integration. Those who supported values integration into school discipline pointed out that it is an integral part of life-education. On the other hand, those who oppose integrating values argued that values integration might be misused to impose secular influences on the learners. The existing avenues of optimal integration of values into school discipline include use of physical punishment and restorative justice, although custodial methods are widely condemned by human rights activists for being too harsh, punitive and retaliatory. Restorative justice methods used include the use of religious and social clubs as well as counseling and guidance. Collective stakeholder participation in school management is also widely used where school management, government, parents and the community take on a collaborative role in empowering and creating an environment for positive discipline. Finally, missionary educators play a significant role in learners’ behavioural modification. The challenges of values integration into school discipline, on the other hand, are policy-related; including poor school administrative styles, failure to define which values to emphasize in disciplinary management, lack of staff motivation and educators’ unethical behaviour. The classroom-related challenges were an over emphasis on academic values that, consequently, turn education into a theoretical rather than a practical exercise. This is compounded by the poor teaching methodologies used like rote-learning due to the problem of dealing with large classes especially in UPE and USE schools and the strict emphasis on an examination-centered syllabus. The social-related challenge observed was the negative influence of the media on young people’s life styles, consequently, leading to permissiveness, aggressive, violent and militant behaviours now common in schools. The study underscored the need to emphasise stakeholder responsibility in school disciplinary management, and the necessity to offer visionary and collegial leadership, identify a common set of values critical to the promotion of life-long learning, promotion of life-education to ensure formation of morally upright learners, and encourage inclusive education (UBUNTUISM). Government should draft a national education philosophy to guide schools in integration of values education, emphasizing secular, moral and religious values, as well as the need for restorative justice, and employing more pragmatic teaching methodologies. There is also the need to create role-models and staff motivation. All these are cardinal remedies in ensuring constructive school discipline. Finally, the central theory that explains the integration is an Integrated Values Framework (IVF) for Positive Discipline (PD). It advocates that discipline is a process of nurturing learners through the provision of inclusive education, life-long learning and citizenship building.

- Description: At a glance, this study is a critique of local development policies with specific reference to the Buffalo City and Nelson Mandela Metropolitan Municipalities in the Eastern Cape. The researcher enters the debate by posing a primary research question: Do the Public-Private Partnerships (PPP) and Broad-Based Black Economic Empowerment (BBBEE) ventures that constitute anti-poverty strategies succeed in addressing the issues of poverty, and achieving more equitable development at the municipal level in the Eastern Cape? This research proposes a problem statement: The local development policies of PPP and BBBEE that are being applied through Local Economic Development strategies are not in the interests of the majority of people living in the Eastern Cape. At a methodological level this research employs both quantitative and qualitative approaches to answer the central question and to verify the problem statement of this study. This triangulation approach is employed to utilize the strengths of both quantitative and qualitative methods. More specifically, the researcher uses a number of different research instruments to collect the data including four hundred questionnaires, four focus groups and elite interviews in both municipalities. The findings of this study indicate that local development policies in both municipalities do not improve the lives of the people. This line of thinking is indicated by both the empirical study conducted by the researcher and is supported by a number of scholarly materials. This study contributes to the body of knowledge in Political Economy and Development Studies including other disciplines in Social and Economic Sciences. The central argument of this thesis is that both BBBEE and PPPs are inspired by neo-liberalism (BBBEE is not neo-liberal per se though it may be heavily influenced by it) and neo-liberalism in practice is contradictory in nature as it involves the allocation of state resources to politically influential individuals, rather than promoting economic development for the majority. The evidence of this research further shows that the local business and political elites through the BBBEE, PPPs and outsourcing of services are using their strong networks (associated political, social and capital resources) in their efforts for personal accumulation. The researcher in this study examines the local development policies from a particular standpoint which is a political economy approach. The business and political elites according to political economic perspective use state resources to enrich themselves.
