- Description: In recent years South Africa has experienced numerous service delivery protests. These protests are a result of the lack of delivery of basic services such as water and sanitation (amongst others). To address this, local governments have taken part in benchmarking initiatives (National Benchmarking Initiative, Municipal Benchmarking Initiative) and regulation programmes (BlueDrop,GreenDrop) in an effort to improve the quality of potable water and sanitation services. The latter of these focuses on the quality of the water services delivered and neither focus on the efficiency with which this delivery is achieved. This study uses both nonparametric (data envelopment analysis) aswell as parametric (stochastic frontier) methods to assess the efficiency of water service provision in South Africa over a six year period from 2005 to 2010. Subsequently, the method which is most suited for use in the South African context is proposed. In addition, this study demonstrates how these methods can be used to determine the effectiveness of benchmarking initiatives, namely the National Benchmarking Initiative, in improving the efficiency of water service provision. Furthermore, additional insight into the selection ofm in them out of n bootstrap procedure for efficiency evaluations is established through a simulation study. The inclusion of efficiency evaluations into South African benchmarking initiatives provides new and important insight into the standard of water service delivery. As such, the techniques used in this study illustrate how efficiency analysis can enhance benchmarking initiatives in South Africa.

- Description: Healthcare services are important to maintaining and improving the wellbeing of a country’s citizens. Nurses are part of medical professionals who ensure that the health and wellbeing of patients are maintained, improved and restored. In order to ensure that nurses provide quality services to patients, healthcare institutions are required to address the health and safety needs within their institutions. This implies that public health institutions are required to protect the health and wellbeing of nurses by implementing safety measures within the institutions. The commitment towards the implementation of safety measures in public health institutions is crucial in order to protect the health of nurses, patients and their families. Should public health institutions neglect the implementation of safety measures, and safety management, it will lead to exposure to risks and hazards, high nurse turnover, an increase in costs and a decrease in profitability. This study investigated employee commitment towards the implementation of safety measures in public healthcare institutions. Furthermore, this study investigated the influence of employee commitment towards the implementation of safety measures on employee retention and organisational performance. This study utilised questionnaires to gather primary data from a total number of 1400 nurses from public healthcare institutions located in the Eastern Cape and KwaZulu-Natal provinces. The primary data was subjected to five types of analysis, namely, reliability, exploratory factor analysis (EFA), descriptive statistics, multiple regression analysis and correlation analysis. The empirical results of this study reveal that there is a relationship between migration, role considerations, health environment, organisational support, work conditions (enabling environment and benefits) and employee commitment to the implementation of safety measures related to safety compliance.

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

- Description: The extended role of today’s pharmacist with the emphasis on patient-focused care has highlighted the need for increased exposure of undergraduate pharmacy students to experiential learning in patient-centred environments, and additional skills development in therapeutics, problem solving and clinical decision making. At the Nelson Mandela Metropolitan University (NMMU), final year pharmacy students complete a university-coordinated, hospital-based, structured experiential learning programme (ELP) for the exit-level module, Pharmacology4. However, the students consistently experience difficulties in the application of pharmacological knowledge during the transition from lecture-based learning to the patient-focused clinical setting. The student population at the NMMU is diverse, with varied cultural, ethnic, language and secondary level education backgrounds, as well as different learning preferences and approaches. The extent to which these factors affect academic achievement in the experiential learning environment is unknown. Central research question The central research question for this study was therefore, “What would be the effect of an intervention aimed at supporting undergraduate pharmacy students during clinical placements, on academic achievement in, and student attitudes towards, experiential learning programmes (ELP)?” In order to explore the research question, several factors which may influence academic achievement in ELPs were investigated, namely: academic achievement (pre-university, in the BPharm programme and, in pharmacology); the admission route into the BPharm programme and the subsequent rate of academic progression; English reading comprehension ability; learning styles; problem solving ability; the extent to which students are prepared for application of knowledge in the ELP, in terms of assessment methods used prior to the final year and previous pharmacy work-based experience. In addition, the students’ lived experience of the ELP was explored, and the need for, and nature of, an intervention was determined. The research was based in a pragmatic paradigm, using an advanced mixed methods approach. An intervention-based, two-phase, quasi-experimental design was employed with an initial exploratory Preliminary Phase (in 2013) preceding the larger experimental framework (Phases One and Two, in 2014 and 2015 respectively). The research design was primarily quantitative, with pre- and post- testing conducted before and after the ELP. The ELP was completed by the comparator cohort in Phase One and the experimental cohort in Phase Two. Supplementary qualitative data was collected before, during and after the ELP. The intervention, in the form of supplementary academic support sessions, was developed from the qualitative data using an iterative approach, and implemented during the ELP in Phase Two. Attitudes and expectations of the students towards the hospital-based ELP were generally positive and realistic. Areas of concern included the difficulties experienced in the application and integration of pharmacological knowledge, both in the clinical setting and the clinical case study-based assessments; students feeling overwhelmed, inadequate and inferior in the clinical environment, compounded by an absence of clinical pharmacists as role models; and feeling unprepared for patient-focused care. The qualitative data strongly supported the need for supplementary academic support sessions. The intervention was developed and implemented in Phase Two, using patient case-based, active learning strategies. The majority of students (91.0%; n = 104) reported improved case analysis skills. A statistically significant (p = .030, Cohen’s d = 0.34) improvement was noted in the summative Pharmacology4 assessment marks obtained by the experimental cohort post-intervention, although of small practical significance. Predictors of academic achievement in the ELP were found to be language, specifically English reading comprehension skills, academic achievement in the BPharm programme and pharmacology, the university admission score, the rate of academic progression, and problem solving ability. Previous pharmacy-based work experience and assessment questions requiring application of knowledge were also found to influence achievement in the ELP. The need for an intervention in the form of supplementary academic support sessions was confirmed. The intervention was subsequently developed and successfully implemented, with student-reported self-perceived improvements in patient case analysis skills. These positive findings were supported by quantitative data which showed a statistically significant improvement in academic achievement in the ELP. Several predictors of academic achievement in the ELP were identified, and invaluable insight was gained into the nature of the difficulties experienced by pharmacy students in the transition from lecture-based learning to experiential learning in patient-focused environments.

- Description: This study was prompted by the prevailing imbalance in financial development across SADC countries, which is not consistent with the linkages and interconnectedness of financial systems of these economies. South Africa is the most financially developed country in Africa, yet it is surrounded by economies with relatively small and underdeveloped financial systems, contrary to the spatial proximity theory in finance. The study performed a number of empirical estimations in respect of the spatiality of financial development, motivated by the intention to assess the growth and spatial spill-over effects of financial development in SADC. The study provides new information in spatial spill-over dynamics of financial development, which could inform policy development particularly in view of the on-going financial integration in the SADC region. The study also contributes to regional economic development in SADC from a finance perspective. The analysis was performed using annual data for all the 15 SADC countries, spanning for the period 1985 to 2014. Using the Generalised Method of Moments approach, the study finds that financial development does not support economic growth in SADC. Financial reforms were found to be insufficient to drive growth. A bi-directional causality between financial development and economic growth was established with causality being strong when flowing from economic growth to financial development. The extended Aghion, Howitt and Mayer-Foulkes Model, estimated by an Autoregressive Distributive Lag approach, established that financial innovation has a positive relation to economic growth in SADC, particularly in the long-run. There is no causality, in either direction, between financial innovation and economic growth in both the short and long-run. The Spatial Durbin Model reveals a presence of positive spatial effects on financial development in the region and that proximity to South Africa yields consistent effects of spatial externality in money markets and inconsistent spatial externality in credit markets. The monetary union has no influence on spatial dynamics of financial development in SADC. The generalised impulse response analysis of a Bayesian VAR model indicate that shocks in South Africa’s financial sector has positive, but constrained and in some cases weak, financial spill-over effects on both economic growth and financial development of other SADC countries. The study established, using the Herfindahl-Hirschman Index, a high level of financial market concentration for SADC, cantered in South Africa, and a fair distribution when South Africa is excluded. Dynamic panel models established that financial market concentration reduces financial development in SADC. South Africa’s financial development has mixed and opposing effects on financial market concentration in SADC. The findings also show that international finance has a positive, but currently weak, effect on financial development in SADC and countries with international financial centres contribute more to financial development than countries without. Proximity to South Africa creates huge potential for increasing financial development in SADC through spill-overs and more benefits of spatial proximity are realised in the long-run. Given the strong spatial effects in money markets and significant positive spill-overs in credit markets in the region, countries closer to South Africa need to link their money and credit markets to the South African markets and possibly benchmark to the Rand so as to benefit from proximity and spill-overs from South Africa. The results also suggest that SADC countries need to capitalise on their proximity to South Africa to enhance financial development by promoting economic growth, financial innovation, opening and diversification of financial sectors and linkages to global financial markets. Financial innovation supports financial inclusion, cross-border flows of funds, remittances and trade in SADC and has effects of enabling integration with developed markets and facilitating economic activity. Opening financial sectors enhances diversification of financial systems, increases competition and efficiency. To enhance access to international finance, the study suggests the creation of information centres in South Africa with SADC countries as economic hinterlands, commercialisation of solutions to SADC countries financial challenges, financial integration and support for deepening of financial systems in these countries. Strengthening economic growth could also increase financial development given a strong demand-following causality. The major challenge, however, is that some of the SADC countries have underdeveloped and highly concentrated financial systems characterised by high financial intermediation inefficiencies, high financial exclusion, weak financial infrastructure and regulations. Consequently, countries suffer financial leakages, are not receptive to spatial externalities and financial spill-overs from South Africa and often generate financial spillbacks to South Africa. SADC countries should, however, first address the issue of financial exclusion, financial infrastructure and regulation as well as efficiency in the financial markets. The SADC countries need mechanisms to attract financial development from South Africa to benefit from positive spill-overs and instruments to deal with negative externalities of financial shocks in South Africa. Overall, there is potential for increased financial development in SADC by consolidating absorption of positive financial spill-overs and externalities of proximity to South Africa -particularly in the medium to long term. Heterogeneity among SADC countries and the varying levels of financial development, however, dictates that the region should promote financial integration in order to enhance development of underdeveloped financial systems through spatial spill-over gains.

A research design that is descriptive and explorative in nature was followed. The research methodology conformed to the following procedure. Firstly, an emission inventory of one hundred and fifty (150) emission sources listed on the data base of the Nelson Mandela Bay Municipality was compiled (“N” and “n” = 150) in a quantitative research approach. Emission data from these sources, together with the relevant meteorological data from the weather stations in the study area (“N” and “n” = 5) were collected and used as input into a geographical information system-software program to quantify the contribution of each emission source to ambient air pollution. The said software program was also used to simulate the dispersion of emissions over the study area. The emission inventory was compiled in consultation with a focus group of experts in the field of air-pollution control in a qualitative-research approach. Secondly, health records of the patients who attend the clinics in the said municipality (“N” and “n” = 49) were assessed for air pollution-related health outcomes. Nineteen (19) of the forty-nine (49) clinics were situated in Sub-District A; fifteen (15) clinics were situated in Sub-District B. The last fifteen of the clinics were situated in Sub-District C, which was also the least-industrialised sub-district. Sub-districts A and B were found to be the most industrialised of the three Sub-districts. Air pollution related health statistics were compiled for the following air-pollution-related health outcomes, namely: lower respiratory tract infections in children under five (5) years of age, as well as pneumonia and asthma in the general population.

- Description: Despite South African citizen’s constitutional right to adequate housing, Government’s housing delivery has been described as a complex, multi-stakeholder, multi-phase problem, exacerbated by political interference and corruption. Housing delivery in South Africa is ideologically and politically designed and executed. However, the government subsidised housing sector remains plagued by: huge and increasing backlogs; corruption; quality concerns, and recipient and stakeholder dissatisfaction. This includes the government subsidised housing construction sector, which faces issues such as: established contractors leaving the sector; late and failed completion; substandard quality; rework; cost overruns; late progress payments; and insolvencies. Moreover, government subsidised housing officials, which forms part of this sector, must contend with abandoned projects and appointing new contractors; shoddy workmanship from sub-standard contractors; remedial work, including demolition and rebuilding; and systemic problems such as staff shortages and under qualified staff. The process of Government’s ideological and political designed and execution may therefore not have considered certain practicalities relative to construction principles and practice. It therefore appears that there may be some relationship between the compatibility of Government’s housing ideological and political designed (policy) and execution and general construction principles and practice. It is clear from the related literature that government subsidised housing construction has mostly been investigated as an exercise observing from the outside in, and not from a construction sector perspective. The main purpose of this study is thus to explore housing policy and practice compatibility as a major obstacle to housing delivery in general and assess whether the current housing policy is sufficiently responsive to the requirements of the government subsidised housing sector by specifically describing and exploring the effects of Government’s housing procurement policies relative to the ability of the construction sector to supply government subsidised housing. More specifically, the study describes and explores corruption, quality; contractors and worker competency, and government capacity as specific consequences of housing policy and practice incompatibility, as well as factors contributing to recipient dissatisfaction and the housing backlog. Finally, based on the finding, a proposed framework for improving the supply of subsidised housing in South Africa has been developed. The methodology for this study adopted a post-positivist philosophy, embracing a quantitative approach using questionnaires, which incorporated mainly five-point Likert type scale, but also multiple-choice questions, as instruments for data collection. Three surveys were conducted, starting with a pilot study and followed by a primary study, during which a total of 2 884 potential participants within the construction sector across South Africa were randomly sampled and solicited to participate, of which 284 responded. The respondents consisted of four groups: general contractors (76); government housing officials (34); built environment professionals (137), and built environment suppliers (37). An electronic questionnaire was sent by email to all potential participants and allowed four weeks to complete the survey. Furthermore, a housing recipient survey was conducted among 100 randomly selected recipients of government subsidised housing in the Nelson Mandela Metropolitan area, by means of a structured interview using a paper based questionnaire, over a period of two weeks. The primary outcome measures used for this study were the ranked mean scores for mainly descriptive analysis and the Chi-square test, the 𝑡-test, Cohan’s d test, ANOVA and Scheffé test, using Cronbach's alpha as a measure of internal consistency of scale and validity, for inferential analyses and hypotheses testing. Hypothesis testing was founded upon Government’s worldview that its policies will not influence the operations of the construction sector relative to housing construction, and therefore tested respondents’ perspectives with respect to the impact that government policies have in terms of contractor operations and contractor success, as well as its contribution towards the housing backlog, substandard housing, recipient dissatisfaction and corruption. The following results were obtained by means of the hypothesis testing:Government housing procurement policies are inappropriate for application in the government subsidised housing sector. Respondents therefore disagree with the notion that government policy and practices do not impact contractor operations and contractor success, and thus the supply of houses; The application of government housing procurement policies leads to inadequate quality. Respondents therefore disagree with the notion that government preferential procurement policies do not impact quality; Government’s housing procurement policies inappropriately target emerging contractors. Respondents therefore disagree with the notion that Government’s targeting of emerging contractors does not impact housing supply; Government has inadequate capacity to address subsidised housing construction sector requirements in terms of housing projects. Respondents therefore disagree with the notion that Government has the capacity to address subsidised housing construction sector requirements in the supply of housing, and Government subsidised houses do not meet recipients’ expectations. Respondents therefore disagree with the notion that government subsidised houses do meet recipients’ expectations. It thus became apparent that housing supply is mostly inhibited by Government’s housing procurement policy, contributing to various factors, such as quality capability, contractor capability, systemic and administrative capacity, and resulting in recipient dissatisfaction. Using Pearson’s product moment correlation, a framework model was developed to illustrate the process flow, which revealed definitive statistical and practical relationships between these factors, and indeed reflects complex relationships between factors inhibiting supply and resulting in recipient dissatisfaction. To find an appropriate framework model for the purpose of improving housing supply, various sources were consulted. Based on the research question, together with the aims and objectives for this study, as well as the realisation that the problems associated with housing supply relate to the project management of the construction phase, which requires interventions for improving supply, it was decided that a results framework would be the most appropriate for this purpose. The proposed framework is therefore a graphical depiction of how the research process may be used to identify problems in the government subsidised housing sector, questioning how these may be resolved, setting strategies to improve the situation, evolving hypotheses and testing these hypotheses to establish the critical factors to be considered in the process of resolving the problem in the housing sector, by means of implementation and feedback.

- Description: It has become generally accepted to refer to today‟s global economy as a knowledge-based economy, since knowledge has increasingly become the resource, instead of a resource for wealth creation. The ability of businesses to harness the potential of intangible assets such as knowledge has become far more decisive than their ability to manage physical assets. In the implementation of knowledge management activities, knowledge sharing is recognised as an integral task and key enabler of knowledge management. Although knowledge sharing is regarded as one of the most crucial factors in the effective management of knowledge, in knowledge-intensive businesses in particular, it has also been established that most employees are reluctant to share knowledge. Research further confirms that the factors that promote or discourage knowledge-sharing behaviour in businesses are poorly understood and that knowledge management systems fail as a result of the misunderstanding of individual characteristics that could influence knowledge sharing. Moreover, the focus of knowledge-sharing literature, in terms of the unit of analysis, is rarely at an individual/micro level, although the role of individuals in the knowledge-sharing process is critical as tacit knowledge resides within the individual and knowledge sharing starts with individuals. Given the importance of understanding knowledge sharing of individuals in knowledge-intensive businesses – but noting the lack of existing systematic, integrated research that focuses on individual-related factors influencing knowledge sharing – the purpose of this study was to fill the gap in the current literature. As such, the primary objective of this research was to identify and empirically investigate the individual-related factors influencing the Knowledge-sharing intention of individual employees in knowledge-intensive businesses. The literature review revealed twelve constructs, namely Individuals’ awareness, Intrinsic motivation, Extrinsic motivation, Transactional psychological contract breach, Relational psychological contract breach, Relationship conflict, Task conflict, Extraversion, Neuroticism, Openness to experience, Agreeableness and Conscientiousness that could influence the dependent variable Knowledge-sharing intention in knowledge-intensive businesses. Various moderating relationships between the dependent and independent variables were also proposed, while seven demographic variables (Age, Gender, Language, Highest qualification, Ethnic background, Organisational tenure and Job tenure of the respondent) were identified as potential control variables. Each construct in the hypothesised model of individual-related factors influencing Knowledge-sharing intention was defined and operationalised using items sourced from validated measuring instruments in previous studies. Several self-generated items based on secondary sources were also formulated. A structured questionnaire was made available to respondents identified by means of the convenience sampling technique, and the data collected from 597 usable questionnaires was subjected to various statistical analyses. An exploratory factor analysis (EFA) was conducted which confirmed the unique factors present in the data, and Cronbach-alpha coefficients were calculated to confirm the reliability of the measuring instrument. Structural equation modelling (SEM) was the main statistical procedure used to test the significance of the relationships hypothesised between the various independent and dependent variables. A subset of SEM, namely general linear modelling (GLM) was used to determine the influence of selected demographic variables on Knowledge-sharing intention and to assess various moderating relationships as proposed in the hypothesised model. The main findings of this study were that personality traits are strong predictors of individual employees‟ willingness to share knowledge, and that the maturity of individuals, in terms of realising the significance and value of sharing their knowledge with others, and in recognising the intrinsic benefits of sharing, influence Knowledge-sharing intention. The main limitations of the study were the use of a convenience sampling technique to collect the data, as well as the dependence of self-report by respondents, which could lead to response bias. This study has added to the body of knowledge management research, in particular knowledge-sharing research, by investigating selected individual-related factors influencing the Knowledge-sharing intention of individuals in a particular subset of businesses, namely knowledge-intensive businesses, and focusing on a particular type of knowledge, namely tacit knowledge. From a business‟s perspective, this study offers recommendations and suggestions for managing these individual-related factors in such a way as to increase knowledge sharing among employees, and as a result, the effectiveness and competitive advantage of knowledge-intensive businesses.

- Description: Among the diverse citizenry that comprise Commonwealth countries are persons affected by disabilities and who remain vulnerable and under-represented. In light of the challenges of under-representation and the stigmatisation of persons with disabilities globally, the democratic principles of the Commonwealth of Nations have been placed under scrutiny. Thus the constitutionality and fairness of governmental policies and national legislation are criticised for their degree of reflection and representation of the social and political rights of persons with disabilities. This thesis will critically analyse the national legislative and policy frameworks affecting persons with disabilities in selected Commonwealth countries. Comparisons will be made between these selected countries, namely Canada, India, Kenya and South Africa. The Commonwealth and subscription to the United Nations’ Convention on the Rights of Persons with Disabilities will serve as a standardised platform for comparisons. Comparisons of the legislative prescriptions of the respective countries will be instrumental highlighting the challenges in the representation of the rights and freedoms of persons with disabilities globally and in improving and strengthening legislative prescription affecting persons with disabilities. The varying levels of development amongst countries and the lack of appropriate infrastructure continue to be detrimental to the effective representation of persons with disabilities and the ability of national governments to develop strong and effective legislative and policy frameworks remains compromised. It is thus essential that attention is directed to the challenges facing countries so that appropriate actions and remediation can improve the vulnerabilities linked to persons with disabilities. This study adopts a theoretical and case law approach. It firstly provides a conceptual framework for disability. The conceptual framework comprises the perspectives on disability that have justified the approaches to persons with disabilities. Theories and values and the international legal framework relevant to persons with disabilities will be provided. The theories and values provide a traditional framework and play an instrumental role in guiding actions toward the effective development of public policy and prescription of legislation. The selected countries will be analysed as separate cases. The countries will be analysed individually prior to the comparative component to acknowledge the strengths, weaknesses and challenges facing each country in relation to its own structure and level of development. The findings are based on themes which emerge from the analysis of the legislation and policies affecting persons with disabilities in the selected countries. The findings are presented in a comparative format owing to the comparative nature of the study. Recommendations that flow from the comparative analysis and findings are proposed in the final chapter. The adoption of the proposed recommendations can strengthen legislative prescriptions affecting persons with disabilities both nationally and internationally and improve the representation of the rights and freedom of persons with disabilities in the global context.

- Description: Albeit in its infancy, South Africa’s LED practice is a benchmark of a large number of African countries in general and Sub-Saharan African countries in particular. The LED practice stands out, for widespread decentralisation of powers, massive and growing LED budgets, robust legal frameworks that govern its implementation and development of LED structures, amongst others. This study seeks to answer three critical questions: What theoretical LED facets (particular aspects) are available in literature? Are these facets being implemented in Nelson Mandela Bay Municipality (NMBM) and Buffalo City Metropolitan Municipality (BCMM)? Besides the effort and monies invested in ingraining LED in South Africa, are the levels of LED practices of the two municipalities deeply embedded in literature? The study utilises a purpose-built tool to measure the level at which LED practice of respective municipalities is ingrained in LED literature. The thesis employed both qualitative and quantitative research methods in order to provide scientifically adequate answers to this research. The former method was employed in identifying available LED facets while, the latter was useful in measuring the level at which LED practice in the two metros is embedded in LED theory. The research findings reveal presence of 6 LED facets, namely, enterprise development, locality development, livelihoods development, workforce development, community development and LED Governance. However, this study discovered that the aforementioned facets fail to cover other general items like the availability or unavailability of LED strategy, functional location of LED within municipal directorates and availability of a budget to drive the LED functions. In light of this, the researcher decided to group all the other key LED functions that he felt were not finding expression under the 6 facets identified in LED literature. This, then, led to the introduction of “General LED” facets. This facet, besides presenting a pre-cursor to the 6 other facets, manages to capture some key factors that are equally behind the success or failure of LED e.g. the LED strategy factor, a factor which a number of sources name “The heart” or “guiding compass” of successful LED implementation. The “General LED” facet contained other factors like: other plans that aided LED, experience of LED practitioners, budget allocation of the LED function, amongst others. The research found that all the 7 facets are being implemented in both municipalities, albeit to varying degrees. The two metropolitan municipalities’ LED practice, with respect to all the identified LED facets, provided some measure of their respective levels of embeddedness in LED theory using a purpose built tool. The embedded (ness) outcome proved that Nelson Mandela Bay Municipality’s LED practice was embedded in the LED theory across all the 7 facets, namely: general LED, enterprise development, locality development, community development, livelihood development, workforce development, and LED governance. The same analysis proved that Buffalo City Metropolitan Municipality’s LED practice was embedded in LED theory in all the other facets bar community development. The survey results revealed that there are inadequate or limited initiatives in Buffalo.

In light of this, the researcher decided to group all the other key LED functions that he felt were not finding expression under the 6 facets identified in LED literature. This, then, led to the introduction of “General LED” facets. This facet, besides presenting a pre-cursor to the 6 other facets, manages to capture some key factors that are equally behind the success or failure of LED e.g. the LED strategy factor, a factor which a number of sources name “The heart” or “guiding compass” of successful LED implementation. The “General LED” facet contained other factors like: other plans that aided LED, experience of LED practitioners, budget allocation of the LED function, amongst others. The research found that all the 7 facets are being implemented in both municipalities, albeit to varying degrees. The two metropolitan municipalities’ LED practice, with respect to all the identified LED facets, provided some measure of their respective levels of embeddedness in LED theory using a purpose built tool. The embedded (ness) outcome proved that Nelson Mandela Bay Municipality’s LED practice was embedded in the LED theory across all the 7 facets, namely: general LED, enterprise development, locality development, community development, livelihood development, workforce development, and LED governance. The same analysis proved that Buffalo City Metropolitan Municipality’s LED practice was embedded in LED theory in all the other facets bar community development. The survey results revealed that there are inadequate or limited initiatives in Buffalo.

- Description: This research critically analysed the role, if any, that is played by the budgetary reforms in enhancing basic service delivery, with specific reference to the case of Amathole District Municipality. The main objectives of this study were to investigate and evaluate the causes of possible challenges encountered by the ADM in the implementation of local government budgetary reforms; to assess and determine the role played by budgetary reforms in promoting basic service delivery by the Amathole District Municipality; to analyse the extent to which budgetary reforms are used in the preparation of the municipal budget and the IDP; and to evaluate the level of ADM institutional capacity in delivering basic services to communities in terms of the municipality’s capital budget and financial plan. The study is premised on the fact that there is no guaranteed service delivery without a sound financial management and planning. In this study, it is acknowledged that municipalities in South Africa are struggling to implement the local government budgetary reforms; and as such, South African municipalities could succeed in rendering effective and efficient public services, provided the matters of governance are adhered to, as well as financial governance in particular. This research is solely based on the assumption that the Amathole District Municipality’s budgets and budget process, like other municipalities in South Africa, are done for the sake of compliance with the requirements of National Treasury and the MFMA – with less emphasis being placed on enhanced basic service delivery to communities. The study proposed to provide a brief literature review on the basic service delivery, with reference to the South African context, as well as a theoretical overview on the evolution of developmental local government budgetary reforms. The empirical survey and research methodology employed in the study are described, followed by the operationalization of the survey questionnaire used for gathering the field data. The research findings of the empirical survey are then statistically analysed, using statistical procedures. The qualitative data analysis involved thematic content analysis, being interpreted and reported on. The triangulation-research methodology was employed with the emphasis being on the quantitative and qualitative methodologies. The sample comprised councillors, officials and ward committee members. Questionnaires, with open and closed-ended questions, were employed for the councillors and the officials. Focus-group interviews were conducted with the ward committee members from the respective local municipalities.The findings strongly suggest that, the introduction of the budgetary reforms indeed resulted in a shift by municipalities from their core mandate – that is service delivery – to a more legislative-compliant mode of practice. Recommendations flowing from, inter alia, the results of the empirical study, are presented to improve financial governance and service delivery in the Amathole District Municipality, as well as in other municipalities in South Africa. If adopted, these recommendations should enable the Amathole District Municipality, as a development agent, to fulfil its developmental mandate, thereby addressing the matters of financial governance and service delivery.

- Description: Patients who are critically ill get often admitted to intensive care units (ICUs). The majority of these patients require support with their breathing and are thus connected to a mechanical ventilator. One aspect to consider in the mechanically ventilated patient is endotracheal tube cuff pressure (ETT) management. The management of ETT cuff pressure entails that nurses working in ICUs have the responsibility of ensuring that ETT cuff pressure is kept within normal range of 20-30 cmH20 for the safety of the patients in order to avoid complication of over and under inflation. Poor management of ETT cuff pressure places the mechanically ventilated patients under risk of tracheal injury. Tracheal injury may also be caused by over or under inflation of the ETT cuff. Over inflation of the ETT cuff can lead to the occlusion of capillaries lining the trachea at the cuff site, tracheal stenosis, and can also lead to the death of mucus membranes around the area, just to mention a few. On the other hand, under inflation of the ETT cuff, can lead to air leaks as well as aspiration of gastric contents into the tracheal tree. Therefore, in order to maintain ETT cuff pressure within normal ranges, evidence-based guidelines related to the management of ETT cuff pressure should be used. However, in Malawi the management of endotracheal tube cuff pressure in mechanically ventilated adult patients by nurses in ICUs is not well explored and it is not clear whether this practice is based on evidence-based guidelines. Furthermore, strategies on how to implement evidence-based guidelines in the ICU might not be known and poorly defined because of the complexity of the context. The study is therefore aimed at implementing and evaluating the effect of an evidence-based guideline on the management of ETT cuff pressure in mechanically ventilated adult patients by nurses in ICUs in Malawi using active (printed educational materials and monitoring visits) and passive (printed educational materials only) implementation strategies. The research study used a quantitative approach with multi-designs. Four phases were used in order to achieve the four objectives that were set. Phase one was the pre-test and used a survey design, two was the expert panel review of the evidence-based guideline, three was the implementation of the reviewed evidence-based guideline using a randomised controlled trial design and phase four was the post-test which used a survey design. The RCT included 25 participants from the control and 27 from the intervention group. Each group had three ICUs of which one in each group was from a private hospital and the other were government. Data collection in phases one and four was by a hand delivered pre-and post-questionnaire. In phase two the expert panel members with experience in critical care used the AGREE II Instrument to review the evidence-based guideline that was implemented. In order to gather data during the monitoring visits, the researcher recorded field notes. The applications that were developed by the University statistician consultant using visual basic applications in excel were used to analyse data. Two different implementation strategies were used to implement the evidence-based guideline. The control group used passive implementation strategy which was printed educational materials thus the evidence-based guideline and algorithm. The intervention group used both active and passive implementation strategies which was the printed educational materials thus the evidence-based guideline and algorithm plus monitoring visits by the researcher. In order to establish the effect of the implemented evidence-based guideline on the nursing care practice for the management of endotracheal tube cuff pressure an evaluative posttest survey was conducted in phase four of the research study. The results revealed that the majority of participants had gaps in both groups regarding nursing care practice for the management of endotracheal tube cuff pressure for the mechanically ventilated adult patients in the pretest but improved in the posttest. In the control group 52% had very low knowledge score, 16% had low score, 28% average, and 4% high score while in the category of very high score there was nobody. However, in the posttest those in the very low score were only 44% while the percentage in the low score remained 16%. There was an improvement in the average scores in the posttest such that only 44% were in this category. There was no one in the high and very high score in the pretest. On the other hand, in the intervention group, 78% had a very low score, 9% low score, and 13% were in the category of average score, while in the high and very high score category there was zero percent in the pretest. However, there was also an improvement in the posttest such that only 44% a very low knowledge score. But 19% had a low score, there were 37% in the average category and no one was in the high and very high score. Statistical analysis revealed that the results were not significantly different between and within groups. Improvements were observed in the two groups regarding the scientific knowledge scores for the nursing care practices in the posttest. Upon qualitative analysis of the data from the open-ended question, two main themes emerged thus the need for documentation of endotracheal tube cuff and the process of implementation the evidence-based guidelines. Sub themes such as lack of documentation; no part of routine care and monitoring not done at all were identified under the main theme of the need for documentation of ETT cuff pressure. The Guideline itself need to be clear; implementation strategies; follow up; incentives; supervision; incentives; time factor; resources or equipment required for successful implementation; nurses buy-in critical for the implementation; training detrimental to EBP implementation; nurses attitude crucial to implementation of EBGs and knowledge of nurses for guideline essential for the implementation were the sub themes identified under the main theme of the process of implementing the evidence-based guideline. All appropriate ethical considerations such as principles of autonomy and self-determination, confidentiality and anonymity, voluntary participation, right to receive treatment, informed consent, were adhered to throughout the research study. The research study was unique in nature because it was the first of its kind in Malawi and it contributed to the awareness of the recommended practice for management of endotracheal tube cuff pressure in the ICUs in the country by implementing an evidence-based guideline. The unique contribution of the study is that it is a challenge to implement evidence-based guideline in poor and resource constraint countries like Malawi.

- Description: Historically psychobiography has focused to a large extent on the study of pathology in human development. In recent years, scholars in the field of psychobiography have recommended that studies with a eugraphic focus be undertaken, thereby investigating optimal human development. Milton Hyland Erickson (1901-1980) was an American psychologist and psychiatrist. An extraordinary creative individual who conducted pioneering work in the field of hypnosis. Whilst vast publications of his academic work exist and his work is continued through the Milton H. Erickson Foundation and its global subsidiaries, in comparison, his life story has not been the focus of much study. The psychobiographical merit of Erickson as the subject of the study was based on his involvement in interesting and important events, as well as his resilient attitude towards life, during even dire moments. The focus of this psychobiography was to conceptualise Erickson’s life in terms of the principles of Adler’s Individual Psychology and Peterson and Seligman’s Character Strengths and Virtues Classification. Through this process it was aimed to provide descriptions and interpretations of Erickson’s personality in order to illuminate aspects such as his creativity, service to others, and optimism. The study is written from the first person perspective and is rooted in the interpretive paradigm. It utilises a qualitative research approach in order to gain an in-depth understanding of Erickson’s finished life and thereby taking into account contextual factors. The two theoretical frameworks guided the iterative data collection and data analysis processes and the data were organised into a descriptive framework. The method of data analysis was idiographic thus describing the uniqueness of Erickson life. Strategies such as the triangulation of data sources and theory, focusing on aspects of saliency, trustworthiness, and ethics were employed to ensure reliable data extraction and interpretation. The study revealed that both theoretical frameworks were appropriate in their description and interpretation of Erickson’s personality and character strengths. Of significance was the protective role that creativity, social interest, hope, and optimism played against trauma and these emerged as central themes in Erickson’s life in terms of his psychological wellbeing. The findings on creativity and social interest are supported by existing research and theory but also highlight perspectives for future research. Creativity is a key component of knowledge production and therefore research in this area could improve our understanding of how it can be nurtured and developed across the lifespan. Whilst the construct of social interest was integral to this study its validity in terms of providing adequate explanations of how individuals balance their own needs against the needs of others was examined and suggestions of where the theory can be elaborated were highlighted.

- Description: Over the recent past, Uganda has experienced disproportionate volatility in inflation alongside rapid growth of unemployment. Whilst inflation has been curtailed to single digit figures since the economic crisis of the 1970s, nevertheless, in the recent past, inflation volatility and unemployment have constrained Uganda’s growth outlook. Like many various developing countries, Uganda has interacted monetary and fiscal policy frameworks as macroeconomic tools to spur productive growth. Most developing countries like Uganda continue to grapple with the challenges of jobless growth which is largely attributed to unstable inflationary pressures as well as low investment which further eggravated rapid expansion in unemployment levels. Government policy efforts have recently been greatly inhibited by rising youth unemployment rates in the country, this has greatly affected Uganda’s growth dynamics. Whilst developed countries have successfully used monetary and fiscal policy frameworks in their pursuit to macroeconomic stability, due to their complex structural economic dynamics, low income countries face challenges in implementing both monetary and fiscal policy to stabilize their economies. Central banks across all countries strive for low and predictable inflation as key in fostering economic growth. The debate over the applicability between monetary and fiscal policy frameworks in the pursuit of enhanced growth continues among policy analysts. The general observation especially in low income countries pertains to the use and effective coordination of monetary and fiscal policy in efforts to stabilize these economies. Despite numerous public expenditure reforms implemented and decline in poverty levels in Uganda, unemployment continued to rise over the past decade consequently inhibiting the country’s growth prospects which has ultimately undermined the econoimy’s capacity to external shocks. Keynes and the monetarists ignited the contentious debate over the superiority between monetary and fiscal policy frameworks which has transformed macroeconomic policy application. A conducive private sector environment as well as large expansions of infrastructure are key fundamental aspects of the development strategy in developing countries, they enhance growth in per capita income. Whilst the monetary authority emphasizes price stability when formulating policies, the fiscal authority pursues its objectives accommodative of the underlying circumstances in the economy. This study aimed to establish an econometric model to predict the impact of monetary and fiscal policy on unemployment and inflation in Uganda using annual time series data for the period 1980 to 2013. The study sought to investigate the influence of monetary and fiscal policy variables on the Ugandan economy in relation to unemployment and inflation. The analysis in the study is based on a twofold oriented objective. The first objective was to investigate monetary and fiscal policy dynamics in Uganda in relation to unemployment. The second objective examined the conduct of monetary and fiscal policy framework on inflation in Uganda. The study analysis begins with a review of literature on the various monetarists and Keynesian theories in relation to the underlying monetary and fiscal policy frameworks. Considering the analysis was a twofold objective, two empirical models linked to unemployment and inflation as well as their relative determinants are specified. The Empirical literature review examined in the study is based on various monetary and fiscal policy theories as well as empirical works by Keynesians, classical economists and the Friedman views. The time series data used were obtained from published sources of the World Bank and IMF, the Uganda Bureau of Statistics (UBOS), Ministry of Finance, Planning and Economic Development (MoFPED) statistical reports and annual statistical drafts from the Uganda Revenue Authority (URA) and Bank of Uganda (BOU). To empirically investigate the influence of monetary and fiscal policy variables on unemployment and inflation in Uganda, considering the use of two dependent variables i. e unemployment and inflation, hence, two estimation techniques were applied in the study namely; the Modified Ordinary Least Squares that comprise of FMOLS and DOLS and the Autoregressive Distributed Lag (ARDL) approach. The estimation analysis in the study contains two main parts which are spread over two chapters. The first part of the analysis deals with the effects of fiscal and monetary policy on unemployment. The estimation techniques applied in the study included the Fully Modified Ordinary Least Squares (FMOLS) and Dynamic Ordinary Least Squares (DOLS) applied to a Vector Autoregressive (VAR) model. The analysis regressed monetary and fiscal policy aggregates on unemployment in a twofold objective. The first sub section regressed fiscal policy aggregates on unemployment using; total government expenditure, total government revenue, tax revenue and trade openness on unemployment using both FMOLS and DOLS techniques. The second sub-section regressed monetary policy on unemployment using; interest rates, money supply, real effective exchange rates and inflation being regressed against unemployment. To test for presence of unit root among the variables of the sample period of 1980 to 2013, the study employed three approaches; i.e. the Augmented Dickey Fuller (ADF) test, Phillips-Perron (PP) test and Kwiatkowski–Phillips–Schmidt–Shin (KPSS) test. Included in this analysis is the test for structural breaks to further determine stationarity in the data series. The results revealed the presence of structural breaks. Structural breaks tend to inhibit stationarity among the variables at levels. However, when presence of structural breaks is taken into consideration, it simplifies empirical estimation analysis under review. The Johansen Cointegration approach was further applied to establish existence of a stable long-run relationship between monetary policy and fiscal policy as well as their respective variables included in the model in relation to unemployment, this further entailed estimation of FMOLS and DOLS in the model estimation analysis. The results from the above analysys show a negative and statistically significant relationship between total government expenditure (LGOVTEXP) and unemployment (LUNEMPLOYMENT). However, tax revenue, trade openness as well structural reforms which denotes the (SB) coefficient all show a positive and significant relationship with unemployment. Additionally, total government revenue (LGOVTREV) shows a negative relationship with unemployment although statistically insignificant. The DOLS results in this analysis all show statistically insignificant results between all the variables and unemployment. The second subsection using DOLS, analysed the impact of monetary policy on unemployment, revealed a negative and significant relation between interest rates, real exchange rates and structural reforms (SB) with unemployment. Money supply indicates a negative but statistically insignificant relationship with unemployment. However, inflation has a positive and statistically significant relationship with unemployment. The normality tests conducted indicate normal distribution of the residuals. Similiraly, the AR inverse roots show stability of the models estimated whilst the multi-collinearity and Wald tests all showed unbiased estimation results. Having analysed the effects of fiscal and monetary policy on unemployment the interest was to further test the impact of fiscal and monetary policy on inflation. This part constitutes two sub-sections. The ARDL approach ws used to analyse the influence of fiscal policy on inflation. The results reveal a negative and statistically significant relationship between inflation (DLINF) and total government expenditure (DLGOVTEXP) both lagged twice. Similiraly, total government revenue (DLGOVTREV) and tax revenue (DLTAXREV) both lagged once indicate a negative and statistically significant relationship with inflation. However, unemployment lagged three times indicates a negative and statistically insignificant relationship with inflation whilst trade openness lagged three times has a positive and satatistically significant relationship with inflation. The Granger causality test results revealed among all the fiscal policy aggregates used, only inflation Granger causes total government revenue. The second part on the effects of fiscal and monetary policy on inflation used monetary variables; interest rates (DLINT), money supply (DLMS) and real exchange rates (DLREER). The ARDL results revealed all coefficients to have positive signs. Inflation and real exchange rates lagged five and four times respectively have a positive and significant relationship with the dependent variable of inflation. However, interest rate and money supply lagged five and three times respectively show a positive and statistically insignificant relationship with inflation. The estimated model showed no evidence of presence of serial correlation through numerous diagnostic tests performed. These include; heteroscedasticity, residual normality and misspecification tests as well as the Cusum stability tests. Under the analysis of monetary policy dynamics on inflation, the Granger causality test revealed that inflation Granger causes interest rates. Similiraly, real exchange rate Granger causes inflation. The ARDL results in this sub-section suggest that inflation regressed against its own lagged values is statistically significant in explaining variations on inflation. Further, interest rates, money supply and real exchange rates significantly explain variations in inflation during the period under review. The results from the above analysis suggest that firstly, the fiscal authority in Uganda should formulate dynamic as well as robust fiscal reforms that can effeficiently be coordinated with sound monetary policy reforms. This ought to stimulate meaningful economic growth in the economy which would further enhance employment growth. Secondly, policy authorities should implement macroeconomic policies which harmonise public spending whilst at the same keep inflation subdued.

- Description: Over the recent past, Uganda has experienced disproportionate volatility in inflation alongside rapid growth of unemployment. Whilst inflation has been curtailed to single digit figures since the economic crisis of the 1970s, nevertheless, in the recent past, inflation volatility and unemployment have constrained Uganda’s growth outlook. Like many various developing countries, Uganda has interacted monetary and fiscal policy frameworks as macroeconomic tools to spur productive growth. Most developing countries like Uganda continue to grapple with the challenges of jobless growth which is largely attributed to unstable inflationary pressures as well as low investment which further eggravated rapid expansion in unemployment levels. Government policy efforts have recently been greatly inhibited by rising youth unemployment rates in the country, this has greatly affected Uganda’s growth dynamics. Whilst developed countries have successfully used monetary and fiscal policy frameworks in their pursuit to macroeconomic stability, due to their complex structural economic dynamics, low income countries face challenges in implementing both monetary and fiscal policy to stabilize their economies. Central banks across all countries strive for low and predictable inflation as key in fostering economic growth. The debate over the applicability between monetary and fiscal policy frameworks in the pursuit of enhanced growth continues among policy analysts. The general observation especially in low income countries pertains to the use and effective coordination of monetary and fiscal policy in efforts to stabilize these economies. Despite numerous public expenditure reforms implemented and decline in poverty levels in Uganda, unemployment continued to rise over the past decade consequently inhibiting the country’s growth prospects which has ultimately undermined the econoimy’s capacity to external shocks. Keynes and the monetarists ignited the contentious debate over the superiority between monetary and fiscal policy frameworks which has transformed macroeconomic policy application. A conducive private sector environment as well as large expansions of infrastructure are key fundamental aspects of the development strategy in developing countries, they enhance growth in per capita income. Whilst the monetary authority emphasizes price stability when formulating policies, the fiscal authority pursues its objectives accommodative of the underlying circumstances in the economy. This study aimed to establish an econometric model to predict the impact of monetary and fiscal policy on unemployment and inflation in Uganda using annual time series data for the period 1980 to 2013. The study sought to investigate the influence of monetary and fiscal policy variables on the Ugandan economy in relation to unemployment and inflation. The analysis in the study is based on a twofold oriented objective. The first objective was to investigate monetary and fiscal policy dynamics in Uganda in relation to unemployment. The second objective examined the conduct of monetary and fiscal policy framework on inflation in Uganda. The study analysis begins with a review of literature on the various monetarists and Keynesian theories in relation to the underlying monetary and fiscal policy frameworks. Considering the analysis was a twofold objective, two empirical models linked to unemployment and inflation as well as their relative determinants are specified. The Empirical literature review examined in the study is based on various monetary and fiscal policy theories as well as empirical works by Keynesians, classical economists and the Friedman views. The time series data used were obtained from published sources of the World Bank and IMF, the Uganda Bureau of Statistics (UBOS), Ministry of Finance, Planning and Economic Development (MoFPED) statistical reports and annual statistical drafts from the Uganda Revenue Authority (URA) and Bank of Uganda (BOU). To empirically investigate the influence of monetary and fiscal policy variables on unemployment and inflation in Uganda, considering the use of two dependent variables i. e unemployment and inflation, hence, two estimation techniques were applied in the study namely; the Modified Ordinary Least Squares that comprise of FMOLS and DOLS and the Autoregressive Distributed Lag (ARDL) approach. The estimation analysis in the study contains two main parts which are spread over two chapters. The first part of the analysis deals with the effects of fiscal and monetary policy on unemployment. The estimation techniques applied in the study included the Fully Modified Ordinary Least Squares (FMOLS) and Dynamic Ordinary Least Squares (DOLS) applied to a Vector Autoregressive (VAR) model. The analysis regressed monetary and fiscal policy aggregates on unemployment in a twofold objective. The first sub section regressed fiscal policy aggregates on unemployment using; total government expenditure, total government revenue, tax revenue and trade openness on unemployment using both FMOLS and DOLS techniques. The second sub-section regressed monetary policy on unemployment using; interest rates, money supply, real effective exchange rates and inflation being regressed against unemployment. To test for presence of unit root among the variables of the sample period of 1980 to 2013, the study employed three approaches; i.e. the Augmented Dickey Fuller (ADF) test, Phillips-Perron (PP) test and Kwiatkowski–Phillips–Schmidt–Shin (KPSS) test. Included in this analysis is the test for structural breaks to further determine stationarity in the data series. The results revealed the presence of structural breaks. Structural breaks tend to inhibit stationarity among the variables at levels. However, when presence of structural breaks is taken into consideration, it simplifies empirical estimation analysis under review. The Johansen Cointegration approach was further applied to establish existence of a stable long-run relationship between monetary policy and fiscal policy as well as their respective variables included in the model in relation to unemployment, this further entailed estimation of FMOLS and DOLS in the model estimation analysis. The results from the above analysys show a negative and statistically significant relationship between total government expenditure (LGOVTEXP) and unemployment (LUNEMPLOYMENT). However, tax revenue, trade openness as well structural reforms which denotes the (SB) coefficient all show a positive and significant relationship with unemployment. Additionally, total government revenue (LGOVTREV) shows a negative relationship with unemployment although statistically insignificant. The DOLS results in this analysis all show statistically insignificant results between all the variables and unemployment. The second subsection using DOLS, analysed the impact of monetary policy on unemployment, revealed a negative and significant relation between interest rates, real exchange rates and structural reforms (SB) with unemployment. Money supply indicates a negative but statistically insignificant relationship with unemployment. However, inflation has a positive and statistically significant relationship with unemployment. The normality tests conducted indicate normal distribution of the residuals. Similiraly, the AR inverse roots show stability of the models estimated whilst the multi-collinearity and Wald tests all showed unbiased estimation results. Having analysed the effects of fiscal and monetary policy on unemployment the interest was to further test the impact of fiscal and monetary policy on inflation. This part constitutes two sub-sections. The ARDL approach ws used to analyse the influence of fiscal policy on inflation. The results reveal a negative and statistically significant relationship between inflation (DLINF) and total government expenditure (DLGOVTEXP) both lagged twice. Similiraly, total government revenue (DLGOVTREV) and tax revenue (DLTAXREV) both lagged once indicate a negative and statistically significant relationship with inflation. However, unemployment lagged three times indicates a negative and statistically insignificant relationship with inflation whilst trade openness lagged three times has a positive and satatistically significant relationship with inflation. The Granger causality test results revealed among all the fiscal policy aggregates used, only inflation Granger causes total government revenue. The second part on the effects of fiscal and monetary policy on inflation used monetary variables; interest rates (DLINT), money supply (DLMS) and real exchange rates (DLREER). The ARDL results revealed all coefficients to have positive signs. Inflation and real exchange rates lagged five and four times respectively have a positive and significant relationship with the dependent variable of inflation. However, interest rate and money supply lagged five and three times respectively show a positive and statistically insignificant relationship with inflation. The estimated model showed no evidence of presence of serial correlation through numerous diagnostic tests performed. These include; heteroscedasticity, residual normality and misspecification tests as well as the Cusum stability tests. Under the analysis of monetary policy dynamics on inflation, the Granger causality test revealed that inflation Granger causes interest rates. Similiraly, real exchange rate Granger causes inflation. The ARDL results in this sub-section suggest that inflation regressed against its own lagged values is statistically significant in explaining variations on inflation. Further, interest rates, money supply and real exchange rates significantly explain variations in inflation during the period under review. The results from the above analysis suggest that firstly, the fiscal authority in Uganda should formulate dynamic as well as robust fiscal reforms that can effeficiently be coordinated with sound monetary policy reforms. This ought to stimulate meaningful economic growth in the economy which would further enhance employment growth. Secondly, policy authorities should implement macroeconomic policies which harmonise public spending whilst at the same keep inflation subdued. In this regard, inflation targeting policies should be strengthened. Thirdly, the macroeconomic policy framework in Uganda should be coordinated with strong employment targeting policies in an effort to broaden labour market dynamics.

- Description: The under-representation of females at management level due to the glass ceiling effect has globally received considerable attention. Research found that one of the remedies for females to progress beyond the glass ceiling, was access to a mentor in senior management. Females receiving mentoring in the workplace perform at greater levels as they gain reflected power, advise and the right to use essential resources. Yet, access to mentors was recognised as a barrier to females’ professional career success, both in the corporate field and to develop their small businesses. Fortunately, the revolution in technology has led to online mentoring which combines conventional mentoring relationship approaches with new technology and provides wider access to a pool of mentors. The increasing popularity of online mentoring can be attributed to the benefits it offers stereotyped individuals and those from marginalised groups. The purpose of this study therefore was to ascertain the enabling conditions necessary for effective online mentoring in South Africa, as well as how it can be used to develop the careers of females (both corporate employees and small business entrepreneurs). The study followed a mixed method approach with a sequential exploratory design. Background literature on conventional mentoring in addition to oniline mentoring assisted in contextualising the many issues relating to conventional mentoring which also apply to online mentoring. Primary data was collected in three phases (two qualitative and one quantitative). The data collection method for phases one and two of the enquiry was interviews with the use of a semi-structured interview schedule and for phase three, a survey via an online structured questionnaire. The biographical profiles of the participants interviewed during phases one and two were presented as case studies. Based on the content analysis of the qualitative interviews with five South African mentors, six female mentees from Africa, two South African online mentoring field specialists and one United States online mentoring field specialist, three main themes were identified viz. online mentoring processes, challenges and enabling conditions. Online mentoring processes identified for effective online mentoring related to the application-, selection-, matching- and conflict resolution procedures. Mentoring challenges related to matching preferences, technology impediments, cultural fit problems, language differences, lack of mutual trust, scheduling and frequency and duration of meetings, the impersonal nature of online mentoring and specific mentee- and mentor-related challenges. Based on the content analysis, the conditions for creating an effective online mentoring environment addressed some of the challenges alluded to and could be classified as generic, mentee-specific and mentor-specific enablers. Generic online mentoring enablers are those conditions necessary for creating an effective online mentoring environment for the mentoring pair such as the ability to establish a trusting relationship, flexible meeting schedules, training offered, the expression of emotions online, having a technology infrastructure in place, clear objectives and relationship boundaries, a desirable programme- and meeting duration with adequate meetings, using multiple contact methods and following a hybrid mentoring approach. Mentor specific issues to create an effective online mentoring environment are mentors with exceptional personal qualities that are knowledgable and experienced, while mentee specific issues relate to continuous mentee commitment and that mentees should have been previously exposed to mentoring. The constant comparative data analysis provided insight into how similar or dissimilar institutions approach online mentoring process and the challenges related to the local (South African) online mentoring environment as compared to those globally. Sixty-three respondents (South African mentors both male and female and female mentees who have undergone conventional mentoring) completed the online structured questionnaire on their perceptions of the online mentoring conditions necessary for effective online mentoring. From the exploratory factor analysis results of the online survey in phase three of the study, six valid and reliable conditions necessary for online mentoring were identified namely, infrastructure readiness, demographic matching preference, mentor characteristics, the communication process, mentoring pair perceptions and mentoring pair relationship. The multiple regression analysis performed established one statistically significant relationship. The perception that the mentoring pair hold of online mentoring influence the achievements of the mentee. This study has thus identified several conditions necessary for effective online mentoring globally, as well as for South Africa. South Africa has a pool of knowledgeable mentors involved in global online mentoring progammes and they can assist with online mentoring in the South African communities in need of assistance. However, South Africa can learn from well-established global online mentoring institutions how to implement an effective online mentoring programme, but will need the necessary financial resources to do so. This study further provided evidence on how online mentoring can be utilised for the career advancement of female corporate employees and those owning small businesses. Some guidelines were provided on how to overcome the various challenges associated with online mentoring globally, and those specific to South Africa. The use of mobile technology instead of computer-mediated technology was recommended as it provides greater access to online mentoring, especially for rural communities. It is also more user-friendly for those with limited computer technology skills.

- Description: The typical methodology for analytically designing a wind turbine blade is by means of blade element momentum (BEM) theory, whereby the aerofoil angle of attack is optimized to achieve a maximum lift-to-drag ratio. This research aims to show that an alternative optimisation methodology could yield better results, especially in gusty and turbulent wind conditions. This alternative method looks at increasing the aerofoil Reynolds number by increasing the aerofoil chord length. The increased Reynolds number generally increases the e_ectiveness of the aerofoil which would result in a higher or similar lift-to-drag ratio (even at the decreased angle of attacked require to maintain the turbine thrust coe_cient). The bene_t of this design is a atter power curve which causes the turbine to be less sensitive to uctuating winds. Also, the turbine has more torque at startup, allowing for operatation in lower wind speeds. This research is assumed to only be applicable to small wind turbines which operated in a low Reynolds number regime (<500 000), where Reynolds number manipulation is most advantageous.

- Description: The ever-increasing demand for broadband services by end-user devices utilising 3G/4G/LTE and the projected 5G in the last mile will require sustaining broadband supply from fibre-linked terminals. The eventual outcome of the high demand for broadband is strained optical and electronic devices. The backbone optical fibre transport systems and techniques such as dense wavelength division multiplexing (DWDM), higher modulation formats, coherent detection and signal amplification have increased both fibre capacity and spectrum efficiency. A major challenge to fibre capacity and spectrum efficiency is fibre-faults and optical impairments, network management, routing and wavelength assignment (RWA). In this study, DWDM and flexible spectrum techniques such as wavelength assignment and adjustment, wavelength conversion and switching, optical add and drop multiplexing (OADM) and bitrate variable transmission have been experimentally optimized in a laboratory testbed for short- and long-haul optical fibre networks. This work starts by experimentally optimising different transmitters, fibre-types and receivers suitable for implementing cost effective and energy efficient flexible spectrum networks. Vertical cavity surface-emitting lasers (VCSELs) and distributed feedback (DFB) lasers have been studied to provide up to 10 Gb/s per channel in 1310 nm and 1550 nm transmission windows. VCSELs provide wavelength assignment and adjustment. This work utilises the non-return-to-zero (NRZ) on-off keying (OOK) modulation technique and direct detection due to their cost and simplicity. By using positive intrinsic negative (PIN) photo-receivers with error-free BER sensitivity of -18±1 dBm at the acceptable 10-9-bit error rate (BER) threshold level, unamplified transmission distances between 6 km and 76 km have been demonstrated using G.652 and G.655 single mode fibres (SMFs). For the first time, an all optical VCSEL to VCSEL wavelength conversion, switching, transmission at the 1550 nm window and BER evaluation of a NRZ data signal is experimentally demonstrated. With VCSEL wavelength conversion and switching, wavelength adjustments to a spectrum width of 4.8 nm (600 GHz) can be achieved to provide alternative routes to signals when fibre-cuts and wavelength collision occurs therefore enhancing signal continuity. This work also demonstrates a technique of removing and adding a wavelength in a bundle of DWDM and flexible channels using an OADM. This has been implemented using a VCSEL and a fibre Bragg grating (FBG) providing a wavelength isolation ratio of 31.4 dB and ~0.3 𝑑𝐵 add/drop penalty of 8.5 Gb/s signal. As a result, an OADM improves spectrum efficiency by offering wavelength re-use. Optical impairments such as crosstalk, chromatic dispersion (CD) and effects of polarization mode dispersion (PMD) have been experimentally investigated and mitigated. This work showed that crosstalk penalty increased with fibre-length, bitrate, interfering signal power and reduced channel spacing and as a result, a crosstalk-penalty trade-off is required. Effects of CD on a transmitted 10 Gb/s signal were also investigated and its mitigation techniques used to increase the fibre-reach. This work uses the negative dispersion fibres to mitigate the accumulated dispersion over the distance of transmission. A 5 dB sensitivity improvement is reported for an unamplified 76 km using DFB transmitters and combination of NZDSF true-wave reduced slope (TW-RS) and submarine reduced slope (TW-SRS) with + and – dispersion coefficients respectively. We have also demonstrated up to 52 km 10 Gb/s per channel VCSEL-based transmission and reduced net dispersion. Experimental demonstration of forward Raman amplification has achieved a 4.7 dB on-off gain distributed over a 4.8 nm spectral width and a 1.7 dB improvement of receiver sensitivity in Raman-aided 10 Gb/s per wavelength VCSEL transmission. Finally, 4.25-10 Gb/s PON-based point to point (P2P) and point to multipoint (P2MP) broadcast transmission have been experimentally demonstrated. A 10 Gb/s with a 1:8 passive splitter incurred a 3.7 dB penalty for a 24.7 km fibre-link. In summary, this work has demonstrated cost effective and energy efficient potential flexible spectrum techniques for high speed signal transmission. With the optimized network parameters, flexible spectrum is therefore relevant in short-reach, metro-access and long-haul applications for national broadband networks and the Square Kilometre Array (SKA) fibre-based signal and data transmission.

- Description: South Africa have some of the lowest employee engagement scores in the world. Leadership is a key determinant of employee engagement, but existing leadership theories and practices are often ineffective in more humanistic and collectivistic cultures like South Africa. To this end, Ubuntu and servant leadership is posited to positively influence organisational performance by increasing employee engagement. The primary objective of this study is to investigate perceptions regarding the impact of Ubuntu and servant leadership on employee engagement in private organisations of the Eastern Cape. A quantitative research design was utilised and yielded 428 usable questionnaires through nonprobability sampling. The empirical results revealed that the spirit of solidarity dimension of Ubuntu leadership influenced significantly and positively. Furthermore, it was found that survival and spirit of solidarity had a significant and positive influence on organisational performance as measured through the balanced scorecard (BSC). Servant leadership positively and significantly influenced employee engagement and organisational performance. In addition, it was found that employee engagement mediates the relationship between servant leadership and organizational performance. This study has made several significant empirical and theoretical contributions, and can be classified as one of the pioneering attempts to gather empirical evidence on how Ubuntu manifests in the workplace. The high convergent validity of the dimensions of Ubuntu leadership and comparisons to Servant leadership established in this study, provides some proof of its novel contribution towards leadership theory. A highly reliable and valid measuring instrument was developed to evaluate Ubuntu from a leadership perspective. This is a major empirical contribution as, at the time, there were no reliable scales available in South Africa to measure Ubuntu leadership.

- Description: The resurgence of Islam across the globe combined with the resilience that Islamic financial assets have shown against the onslaught of the current financial crisis, make Islamic finance an attractive alternative financial system. Over the past decade, the Islamic finance sector have shown double digit growth rates beyond the traditional areas of the Gulf Cooperation Council (GCC) regions of Asia as well as other parts of the Middle-East and North Africa (MENA) regions. Research suggests that the future of Islamic finance in Africa depends on business opportunities in South Africa, Kenya, Nigeria and Senegal. The South African government, in conjunction with the national finance authorities, have made their intention clear to position the country as the Islamic finance hub for the rest of the African continent. Despite various marketing campaigns over the past decade to convince the public that Islamic banking and finance is for everyone, non-Muslims generally view Islamic banking as being for Muslims alone. Scepticism towards Islamic finance has resulted in a mere 15 per cent of the estimated 1.5 million South African Muslims currently making use of the sector’s banking and retail instruments. This lack of interest is impacting negatively on the country’s aspirations to establish itself as the gateway of Islamic finance to the rest of Africa. Generally, people’s attitudes toward utilising Islamic finance are regarded as a key obstacle to the development of the Islamic banking and finance system in Muslim minority countries. A Kuwait Finance House research report (2012) highlighted a lack of awareness and knowledge of Islamic finance products and services as key factors stifling the growth of the Islamic finance sector in South Africa. In this context, it was deemed necessary to analyse how knowledge, awareness, expectations, beliefs, perceptions and ancillary external factors impact on potential users’ attitude and decision to adopt or reject Islamic finance.By means of adapting Fishbein’s (2000; 2008) Integrative Model of Behavioural Prediction, a universally-acceptable behavioural-change model, this research explains in a holistic manner how cognitive, affective and environmental measures impact on a Port Elizabethan Muslim’s attitude and eventual decision to accept (or reject) Islamic finance. This study has found that knowledge was the most important variable influencing attitude and intention to use (or reject) Islamic finance. Consequently, this thesis proposed that Islamic institutions should focus their efforts on promoting knowledge and awareness of their products among the South African Muslim and non- Muslim population. As the global Shari’ah finance industry continues its positive growth trajectory, it is imperative that Islamic finance stakeholders in South Africa ensure that they exploit the benefits derived from online learning platforms and assist, by means of cross-border collaborations, more students to have greater access to Islamic finance courses. Furthermore, universities and training institutions are encouraged to offer courses and qualifications in Islamic finance to close the talent gap that currently exist in this particular field of study.

- Description: The purpose of this study was to identify and examine pre-service teachers’ concerns relating to their teaching practicum in Zimbabwe and to suggest strategies that could be used to support them in a digitalised era. This study was necessitated by the desire to understand the concerns that pre-service teachers experience during teaching practicum in a fast changing world and in a depressing, unstable socio-politico-economic environment. The study employed a meta-conceptual approach comprising constructivist and social cognitive epistemology as its theoretical framework. A concurrent mixed methods research design was utilised to address the research questions. Both quantitative and qualitative methods were used to design the study, collect, and analyse data. Thirty participants comprising of 24 pre-service teachers and six college supervisors were purposively selected for the qualitative study from United College of Education in Zimbabwe. Qualitative data was collected by means of interviews and analysed through a thematic analysis. For the quantitative phase, 300 pre-service teachers were chosen through stratified random sampling from the same institution and were asked to complete a questionnaire. One hundred and ninety-three questionnaires were returned and usable, giving a return rate of 64%. Data from the survey were analysed using descriptive and inferential statistics. Findings from the study revealed that pre-service teachers experience diverse concerns during teaching practicum that included classroom management, teacher knowledge, socio-economic factors, workload, interpersonal relationships and assessment anxiety. Findings from the quantitative phase revealed some differences in the levels of concerns among the year groups. A general downward trend in the levels of concerns was detected except for teacher beliefs concerns that remained constant. Findings from the qualitative phase of the study revealed that the concerns that pre-service teachers experienced during teaching practicum had negative impact on their classroom practice. Most of the student teachers had devised some coping strategies to deal with their concerns and they were satisfied with the quality of support from mentors and peers, but not that from their supervisors. In an increasingly globalised world, the researcher felt that teaching practicum related concerns could be minimised by exploiting the benefits of digitalised knowledge and communities of learning.
