- Description: This thesis analysed and compared the effectiveness of the anti-corruption legislation and anti-corruption agencies in the Eastern Cape and Northern Cape provinces. The thesis consists of six chapters. This study is based on the assumption that the struggle against corruption is best approached by developing a system of laws, institutions and supporting practices which promote integrity and make corrupt conduct a high-risk activity. It is imperative that a systemic approach is embarked upon in order to address the manner in which the major institutions and processes of the state are conquered and exploited by corrupt individuals and groups. With the magnitude in which hurdles exist that hamper the effectiveness of the country's anti-corruption legislation and anti-corruption agencies; South Africa is incapable of curbing corruption. With the purpose to determine a desired state of affairs, characteristics of effective anti-corruption agencies and anti-corruption legislation were presented. These served as a yardstick in measuring how effective such agencies and legislation are in South Africa. Reasons for failure of agencies and legislation are discussed. After discussing types of anti-corruption agencies, those that perform better than ix others were identified. Through literature review, the status quo concerning anti-corruption initiatives in South Africa was assessed. It was revealed that the level of the success of South African anti-corruption agencies and legislation has been limited. In the case of anti-corruption agencies, weaknesses such as fragmentation; insufficient coordination; poor delineation of responsibility; and assimilation of corruption work into a broader mandate were identified as major causes. Measures that are needed, such as informed citizens; a need to foster and sustain high levels of professional and ethically imbued civil servants; and legislation that supports the transition towards a corruption-free society that are needed to complement implementation of anti-corruption legislation, were also recognised. Ways of addressing such shortcomings that the writers identified are also presented. The methodology and design followed in the study are described. This is followed by the analysis and interpretation of the survey. The research findings are then presented. Based on the findings a number of recommendations that would assist in improving the effectiveness of anticorruption agencies and anti-corruption legislation are made. Flowing from the discussion of effective anti-corruption models that were identified by literature a model that would be ideal for South Africa is recommended.

- Description: Volunteer home-based caregivers are critical role players in South Africa‘s health care system and in the South African government‘s strategy to fight HIV and AIDS. In order to achieve the aims that the government seeks to attain, it is important that the care and treatment provided to patients receiving community home-based care (CHBC) be of a high quality. While the need for quality care is supported by government and civil society, research indicates that it is not clear whether quality care is indeed being provided and therefore there is a need for research into the quality of CHBC. The research aimed to undertake a critical assessment of CHBC programmes to determine the quality of care provided by volunteer caregivers using social capital theory as a theoretical framework. The study examined the quality of CHBC by analysing the context of CHBC, by investigating the support that volunteer caregivers and their clients receive and by discussing the support that volunteer caregivers and their clients still need. The study used one-on-one in-depth interviews and focus groups to obtain relevant data. The participants included volunteer caregivers, clients and supervisors who took part in the one-on-one interviews. The focus groups consisted of key informants and supervisors respectively. The quantitative data consisted of descriptive statistics which helped describe the participants. The qualitative data was coded and themes and sub-themes were developed. The data was also analysed by an independent coder. The results showed that poverty, and the related problems of poor living conditions and a lack of food security affects the quality CHBC. In addition, unemployment and the problem of stipends also affect quality CHBC. Certain socio-economic factors were also found to lead people to choose to become volunteer caregivers and unemployment was found to be an important driving force behind the choice to undertake volunteer caregiving. Furthermore, the volunteer caregivers in the sample received organisational support from their supervisors and their fellow caregivers or peers. They also received social support from their families and their communities. Regarding the clients of the volunteer caregivers, it was found that they received a number of types of support including psycho- iv social counselling, spiritual counselling and care of a holistic nature. In addition, the study found that there is a need for standardised quality training of volunteer caregivers, which will equip them with multiple skills. It was also found that volunteer caregivers require mentoring and quality supervision in order to be able to provide quality CHBC to their clients. Government has the ability to put the necessary systems and structures in place, such as a scope of practice for volunteers, standardised training and monitoring and evaluation, to enable CHBC and its relevant role players to operate at optimum levels. It also has the authority to make the changes and to enforce rules. Furthermore, it has the ability to unite CHBC organisations and can create the necessary conditions that can lead to increased social capital. Furthermore, the study recommends that two additional dimensions of quality care be added to existing dimensions of quality in health care. The first is the holistic approach to caregiving and the second is social support systems, namely supervisor/mentor and peer support and family and community support. This second dimension is also closely linked to social capital and the networks that make up CHBC.

- Description: The South African automotive industry is recognised as an important sector for the economy and has thus been prioritised by the South African government. The success of the automotive manufacturers depends on the efficiency and effectiveness of their supply chain. Due to the large number of suppliers involved in these supply chains, enhancing trust in the inter-organisational relationships can ensure the competitiveness of the supply chain. Additionally, insufficient trust can disrupt information sharing between supply chain partners which further impacts on supply chain operations and hence supply chain competitiveness. Thus, both insufficient trust and insufficient information sharing are viewed as contributing factors to the inefficiency and ineffectiveness of a supply chain’s operations. The use of Information Technology to facilitate inter-organisational relationships, in particular in terms of improving information sharing, is an important consideration in this research project. As in the Prisoner’s Dilemma, when supply chain members share information freely, trust levels are increased, hence supply chain effectiveness and efficiency is achieved and therefore the competitiveness of the supply chain is optimised. This study addresses the problem of enhancing trust in automotive supply chains using Information Technology. Previous studies have recognised the importance of trust and information sharing in supply chain relationships. These previous studies have also considered the effect of trust on information sharing, or the effect of information sharing on trust in a single direction. Thus, to address this research problem, a cyclical relationship between trust and information sharing is proposed. In this respect, Information Technology should be used to nurture this cyclical relationship between trust and information sharing. A model for the enhancement of trust in automotive supply chains through Information Technology is proposed to achieve the objectives of this research project. This model includes risk perception; information sharing as a means of enhancing trust; a trust area that consists of both supply chain partner trustworthiness and system trust; the resultant trusting behaviour; and the resultant improved information sharing. As this study is concerned with the use of IT to enhance trust, the inclusion of system trust as a component of the model is a significant contribution of this study which is complementary to the proposed cyclical relationship between trust and information sharing.

- Description: The focus of this study is the Southern African Development Community (SADC) preventive diplomacy interventions in Lesotho in 1994, 1998 and 2007. The core aim of the study was to evaluate the efficacy of the SADC security mechanism (the Organ on Politics, Defence and Security (OPDS) in conflict prevention, management and resolution on the basis of the Lesotho experience. Data for this qualitative case study was collected through interviews and document analysis. The twenty four participants for the study were drawn from the SADC OPDS unit, Lesotho political parties, Civil Society Organisations (CSOs), Academics from the University of Botswana (UB) and the National University of Lesotho (NUL), retired Botswana Defence officers who participated in the Lesotho missions and office of the post-2007election dispute dialogue facilitator in Lesotho. Documents on the SADC Treaties, Protocols, Communiqués and interventions in other set ups were used to highlight its operational policies, mandate, structures, successes and challenges. Lesotho was chosen as a case study because SADC employed both non-coercive (SADC Troika and Eminent Person mediation, 1994 and 2007 respectively) and coercive measures (the 1998 military intervention). The findings of the study revealed that SADC as a regional body had its own successes and challenges. Different perceptions on the SADC interventions in Lesotho emerged mainly between the participants from the ruling party and the opposition parties. While the former commended SADC for successfully mitigating the calamitous effects of 1994, 1998 and 2007 post-electoral violence, the opposition parties viewed the regional organisations as engaged in illegal interference in the domestic affairs of the country to defend the incumbent governing party. It also emerged from the study that the SADC security mechanism has numerous structural and operational flaws. There were several unanswered questions revolving around the legality and mandate of some of the missions. For instance, no concrete evidence emerged as to whether the 1998 military intervention was authorised by the SADC. The study also revealed that SADC has learnt valuable lessons from the Lesotho missions. Some of the reforms which the SADC has introduced in the OPDS such as the establishment of the SADC Stand by Force, Early Warning structures, the Mediation Unit, and a panel of expert mediators emanated mainly from the Lesotho experiences. The study recommends that SADC needs to harmonise the efforts of its OPDS structures such as the Mediation Unit; the Troika; the Inter-State Defence and Security Committee (ISDSC); the Inter-State Politics and Diplomacy Committee (ISPDC) and the Summit of Heads of States and Governments for rapid, coherent and well coordinated interventions in future regional preventive missions. It is also recommended that SADC should focus on identifying and mitigating underlying causal factors such as underdevelopment; poverty; deprivation of freedoms, marginalisation and other forms of social stratifications and oppression in its preventive diplomacy missions if durable peace is to be achieved in Lesotho and any other future cases.

- Description: The assessment of the motivational value of rewards in the world of work is interesting but difficult to understand. Variations in research reports and inadequate comprehension of the efficiency and motivational value of rewards have brought about confusions, controversies and contradictions among authors, researchers, consultants and practitioners in the field of Industrial and Organisational Psychology (Mangham, 2007; Muula, 2006; Muula & Maseko, 2005; Palmer, 2006; World Bank, 2004). As a consequence, organisations are applying theories and models of motivation selectively depending on their beliefs, ideological framework of values and assumptions (Dzimbiri, 2009). The study was therefore carried out as a positive contribution to the existing knowledge and debate on the motivational value of rewards for health professionals in the public health sectors of the developing countries. Through a systematic sampling method, 571 health professionals were sampled for the study. Data were collected through the use of a self-administered questionnaire which was composed based on the data collected from desk research/literature review, focus group discussions and interviews. The findings of the study revealed that the Malawi‟s Ministry of Health (MoH) is failing to attract, motivate and retain health professionals; there is perception of inequity of the rewards among the health professionals; health professionals develop coping strategies to supplement their monthly financial rewards; health professionals engage in corrupt practices to supplement their monthly financial rewards; and there is erosion of industrial democracy in the Malawi‟s Public Health Sector. While the statistical testing of the hypothesized model proved a lack of fit between the variables, the statistical testing of the re-specified model suggests that there is a positive relationship between financial rewards and reward-related problems being faced by health professionals in the Malawi‟s MoH. Through the Structural Equation Modeling (SEM) exercise, an inverse (negative) relationship between financial and non-financial rewards was deduced, and scientifically and graphically demonstrated. Both the re-specified and graphical models symbolize a pragmatic departure from the theoretical model whose authors (Franco, Bennett, Kanfer & Stubblebine, 2004) are largely inclined to the use of non-financial rewards and suggest that financial rewards should be used with caution. These findings also reject the Herzberg‟s two factor theory (Herzberg, 1960) which claims that financial rewards (salaries) are not a motivator. The major recommendations of the study are that the Franco et al.‟s (2004) model should be adopted and adapted in the Malawi‟s MoH with the view that the value of both financial and non-financial rewards (as motivators) varies from individual to individual due to individual differences and prevailing factors/forces in both the work environment and wider society in which the MoH operates; a hybrid reward system combining the strengths of time-based, performance-based and competence-based reward systems should be developed and implemented; the results of scientifically testing the re-specified model and the inverse (causal) relationship established between financial and non-financial rewards (as demonstrated in a graphic model) should be re-tested with other samples in the public health sectors of the developing countries; and the motivational value of non-financial rewards should be scientifically established and compared with the motivational value of financial rewards used independent of each other in business organisations to make an objective conclusion on the rewards-motivation debate.

- 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: 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.

- 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.

- 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.
