- Description: Growth in information and communication technology (ICT) is drastically changing the way businesses, especially in the service industries, are conducted. The financial services industry and banking in particular, is not excluded from this technology explosion. Internet banking, even though not new in advanced countries, is a new transaction channel being used by banks in some parts of Africa, especially Ghana, to offer various products and services to their customers. However, this medium has not been fully exploited by these banks as there are many hurdles the banks must triumph over. In deploying this technology and these systems, there are several factors which banks must take into consideration before fully deploying such a system to their customers, hence the motivation for this study. The absence of suitable and sufficient knowledge on this topic also exposes a “rhetoric versus reality” argument of whether the intention to adopt Internet banking is critical to the strategies and ultimate success of banks in Ghana. For banks to stay ahead of competition as well as to attract and maintain their clientele, it is of paramount importance to gather and link the perspectives of both clients and bank managers in order for banks to ensure that they perform according to the needs and expectations of their clients. In order to achieve the intended results, an empirical study was conducted by taking into consideration the viewpoints of both bank clients and bank managers in determining the factors that customers take into consideration before adopting the Internet banking medium. The primary aim of this study was to quantify significant relationships between the selected variables. Therefore the positivism research paradigm was used, while the phenomenological paradigm was employed for the measuring instruments. Because multiple sources of data were used, from the perspectives of banking clients and managers in Ghana, methodological triangulation was adopted for this study. The results of the empirical investigation showed that both groups (clients and managers) considered the variables of market share, technology acceptance, diffusion of innovation, organisational variables, organisational efficiency, and business strategy to have direct influence on the adoption of Internet banking. However, they differed in opinion concerning the degree of influence of these variables. The bank managers’ responses leaned more towards strong agreement with the importance of these variables than did those of the bank clients. Thus, for bank clients to readily adopt the Internet banking medium for their banking transactions, bank managers must take a closer look at these determinant factors described in the study. The study showed that the population group, educational and income levels exerted an influence on the perceptions clients have regarding Internet banking adoption factors. It was found that the higher the education and income levels of the clients, the easier it was for them to adopt Internet banking. Also, the male group dominated the use of the Internet banking. This is supported by the fact that there is a growing middle class in Ghana that falls within this category of banking clients.

- Description: This study investigated the capacity building for developmental local government with reference to the Kicukiro District of Rwanda. Its aim was to examine the contribution of capacity-building interventions towards a developmental local government and at the same time investigate factors that hinder their implementation in Kicukiro district. The study provides an extensive historical background on local government in Rwa-nda with a particular focus on its policy, legal and institutional framework, whereby the developmental local government environment has been analysed. Furthermore, this study explores the theoretical framework of capacity building in general, and in this regard particular emphasis was given to capacity building in relation to developmental local government. The study also argued that without appropriate capacity it would be difficult for the district to fulfil its developmental mandate. This research followed both qualitative and quantitative approaches of study. It involved a survey in which a structured questionnaire and in-depth interviews were used as data gathering instruments. Through data analysis, findings of the study have shed light on the fact that capacity building constitutes an indispensable mechanism for local government to achieve its developmental mandate, despite challenges associated with the process of capacity building. The study found that the Kicukiro district has made a significant progress towards the implementation of capacity-building interventions despite the fact that these interventions are still fragmented, uncoordinated and still supply-driven. Furthermore, the study revealed that the capacities already built generated considerable impetus that contributed to socio-economic development within the Kicukiro district. The study also found that despite the progress made in both capacity building and development in Kicukiro district, there are capacity gaps and factors which are undermining further progress in this regard. Therefore, the study recommends, among others, an effective co-ordination of capacity-building interventions in order to avoid duplication and fragmentation of capacity-building efforts.

- Description: Utilising the Grounded Theory Research Method, this study identified a range of open, axial and selective codes, through a literature review, which resulted in the formulation of a proposed theory of how war economies are formed and maintained. Based on the theoretical proposition of the proposed theory, a policy framework for dismantling such war economies was also developed and presented. The proposed theory of war economies essentially argues that war economies are formed in post-colonial sub-Saharan Africa because of the existence of an artificial state. The existence of an artificial state is ascribed to the emerging legacies of colonial state formation processes, which created failed state entities which are unable to produce public goods for all its citizens because of its inability to maintain a monopoly of violence whilst maintain full administrative control over its territory. This inability results in an increase in the vulnerability of state and non-state actors. In response to these vulnerabilities, both state and non-state actors established a range of parallel political, economic and military structures. These structures in turn made use of both network and resource capacities to create an environment where politics are economised and conflict is commercialised, in order to mitigate the impacts of state failure and the inability to produce public goods. The result of the creation of an environment where politics are economised and conflict is commercialised, is the creation of incentives, structures and processes to ensure that conflict and associated conditions of instability are sustained in order to ensure primitive accumulation of wealth and resources. Based on the core theoretical proposition of the proposed theory, the study also presents a broad policy framework for dismantling war economies. In broad terms the framework proposes an integrated state-building process, based on a range of policy mechanisms aimed at maintaining a monopoly over violence, increasing administrative control, dismantling conflict networks and ensuring effective and efficient resource management.

- Description: Approximately sixty percent of Africans depend on rainfed agriculture for their livelihoods. South Africa is evidenced to be susceptible to inclement climate which impacts on rural livelihoods as well as on farming systems. While South Africa is considered to be food sufficient, it is estimated that approximately 35percent of the population is vulnerable to food insecurity. Therefore with the application of surveys and interviews this study investigates the factors influencing household, subsistence and small-scale farmer perceptions of vulnerability to climate variability as well as the determinants of adaptive capacity. A sample of 308 households is surveyed and four focus group discussions are administered in Ngqushwa Local Municipality as a case study. Furthermore, the study also focuses on the biophysical changes or factors (scientific analysis of the prevailing climatic regimes–rainfall trends); the interrogation of the impact of food systems on both food prices as well as its implications on food sovereignty. The study also interrogates the relationship between crop yield and rainfall data over a 30-year period. Therefore the study adopts a mixed method approach to ensure triangulation. The study finds that rural communities are able to perceive climate variability and its related changes as well as its negative impact on crop production, food access and availability. The perceived rainfall trends also corroborate this Pearson product-moment correlation coefficient reveals that there is a strong correlation between crop yields and rainfall (r = 0.69). Meteorological analyses also show that the rainfall trend has been significantly variable over 112 years (1900 - 2011) with several dry spells threatening the subsistence and small-scale farmers’ sustainable livelihoods. The food systems pose threats to food safety, food security and historical food sovereignty for the rural community of Ngqushwa Local Municipality. Adaptive capacity is greatly impaired by the lack of co-ordination of adaptation strategies, which communally benefit the majority of the farming respondents in the study area. Therefore vulnerability to climate variability impacts on the ability of the respondents to achieve food security. The study also finds that there is perceived competition between the farmers and wild life for the natural resources. The respondents’ perception is that climate variability and change is responsible for such competition. The study recommends that the national, provincial and local governments must foster a new food production model that is not based on the agro-business model and its attendant technologies but on one that is based on robust agro-ecological farming techniques which enhance adaptive capacity; which foster food safety; which promote food sovereignty; and which reduce vulnerability in a sustainable manner. Given the extent of climate variability in the study area the restoration of the NLM weather station infrastructure can also aid the farmers in taking advantage of a robust early warning system for better estimation of climate trends which enhance crop production.

- Description: Nurses are confronted with numerous work-related stressors that can result in burnout. This can contribute to absenteeism and high turn-over rates in the nursing profession. A review of the literature indicated that psycho-educational interventions to increase resilience could be an effective way of addressing this problem. The study aimed to develop a positive clinical-psychology approach to increasing resilience in State employed nurses. The study used a mixed-method approach to determine the current psychological functioning of a sample of 87 nurses. Quantitative data on personality traits, character strengths and levels of resilience were obtained, using the NEO PI-R, VIA – IS, and Resilience Scale. Qualitative data on the coping responses of nurses were obtained through the thematic analysis of focus groups. These data were integrated to create a positive clinical psychology conceptualisation of resilience and to develop therapeutic guidelines for a group psycho-educational intervention. The results of the study indicated a struggling psychological profile. This was defined as the ability to deal with work-related stressors – but with the potential risk of developing symptoms of burnout. The moderate levels of resilience were attributed to elevated character strengths in the sample. The distribution of personality traits indicated that the nurses in the sample were at risk of developing burnout; and this prevented them from flourishing. These data were synthesised to create therapeutic guidelines for developing resilience aimed: (1) increasing emotional stability and invulnerability; (2) increasing agreeableness; and (3) increasing conscientiousness. These guidelines were based on the personality traits that were deemed to negatively impact the resilience of the nurses. These personality traits were correlated with several character strengths that displayed strong relationships with resilience. This indicated that resilience could be developed through the cultivation of the following character strengths: perspective; perseverance; fairness; forgiveness; leadership; love; zest; hope; curiosity; and appreciation of beauty and excellence. These character strengths were identified to facilitate the positive adaptation of the personality traits identified in the therapeutic guidelines. A group psycho-educational intervention was developed, using the positive clinical psychology conceptualisation of resilience. The literature was reviewed to identify techniques to cultivate the ten character strengths specified in the therapeutic guidelines. These techniques were adapted to create experiential learning processes for the intervention. This psycho-educational programme can be applied as a secondary and tertiary intervention. It can be used to increase resilience to prevent burnout among nurses. It can also be used to psychologically empower nurses that have existing symptoms of burnout.

A sociological analysis of biodiversity management in Nigeria

- Description: The central thesis of this study addresses biodiversity challenges from a social relations perspective. This is viewed from the standpoint of enhancing sustainable bioresource-use systems from a behaviour change departure. The study reviewed the activities of organisations in Nigeria which focus on bioresource management. The review focused on how the organisations view, conceive and implement activities which aim to address biodiversity loss emphasising how these aspects inform the concept of programme design, planning and implementation. The strategies were weighed against theories and techniques in behaviour change. The study argues that it should be recognised that the challenges of biodiversity loss have a strong relationship with how a society is socially constructed, and that addressing the challenges will require a systematic approach aimed at social construction, using efficient techniques to ensure behaviour change. The objective of the study was to acquire insight on how programmes which aim at addressing biodiversity loss in Nigeria approached behaviour change towards sustainable bioresource-use practise. The study captured these insights in a set of themes which provided an improved analysis on the dynamics of behaviour change and biodiversity management in Nigeria as well as extrapolated these findings to articulate new ideas on how to address the challenges of biodiversity loss in Nigeria. Through analysing basic suppositions and exposing contradictions, social science disciplines examine the credibility of arguments and key concepts that commonly remain unquestioned. Based on this premise, critical assumptions on biodiversity management were challenged by the study. Furthermore, the study articulated questions which have been raised in recent years from a variety of social science perspectives on biodiversity management concerns. The study postulated the need for biodiversity management to be approached from a social-construct perspective in rethinking the discourse on unsustainable bioresource-use patterns. The thesis derives from an eco-sociology framework rooted in human interaction analysis, which is connected with approaches in the social science of functionalism and behaviourism. The concepts and ideas discussed in the thesis lay out the main dimensions relevant to the discourse on behaviour change-biodiversity management. The study’s conceptual and theoretical underpinning discussed biodiversity management concerns from a global context and narrowed the discussion down to country specific contexts. Within these contexts, the study discussed issues of policies, legal systems, political and social systems, practices and programme activities, as part of management concerns. The study compiled relevant views on conservation and protection practises which were in line with internationally accepted norms and practises on biodiversity management. It highlights the challenges of current practises which emphasise strengthening of legal frameworks, policies and practises, and which criminalise actions that contravene ideally-construed conservation precepts as best models of addressing biodiversity loss. It further discussed the emphasis placed on protected-area systems as the main model of biodiversity conservation and argued on the need to rethink the approach within the Nigerian context. The study articulates the role of sociology in ecological discourse and argues that although the knowledge gained by physical and biological sciences are essential in addressing ecological challenges, however, they are not sufficient to understand the driving forces underlying ecological challenges and the phenomenon fundamental to understanding trends and patterns of human factors in biodiversity loss. The study was explored within the methodological framework of phenomenology as the underpinning paradigm using a qualitative approach for analysis. The layouts of the thesis ensure that the research moves from theoretical and conceptual reflections to the actualities of lived realities and situated practices embedded in biodiversity management in Nigeria. The conceptual inclination for the theoretical base for the study analysis was postulated, which articulate the study’s scientific and empirical contributions. The survey method reflects exploratory analytical inquiry which supported the study’s methodological considerations. This was based on the specific data chosen for review, which was informed by the selected organisation’s application of social-construct concepts. Considered from a national perspective, the study assumed that issues of biodiversity management concerns were not to be separated from everyday social realities and the larger social challenges. In view of this consideration, the study analysis looked at historical, political and socio-economic backdrops in Nigeria, which reflected on bioresource-use practises. These are relevant to understand the dynamics and interplay of culture and values in bioresource-use patterns. The study builds on diverse arrays of global frameworks to integrate the major findings of the study. These were compared with related and different dimensions as well as existing theories of human-bioresource interactions. The first aspect of the empirical analysis explored conceptual dimensions which raised questions concerning perceptions of reality and social values that were linked to the strategies of social-constructs expressed through policies, plans and practices. The study’s fundamental empirical dimension explored the forms in which programmes and social institutions were relevant in ensuring behaviour change towards sustainable bioresource-use practise. The analytical sequences observed trends which support facilitation of social change through behaviour change. Another aspect of the empirical analysis focused on revealing the processional dynamics of programme activities to achieve set objectives. This was analysed from the methodical perspective of how the processes were monitored and measured in order to achieve anticipated outcomes. The study summarised the findings and the outcomes by outlining the themes which emerged from the research. The study analysis argued that the ideals of social interventions cannot be different from a society’s inherent and attributed meanings to realities, as well as how they engage with their everyday realities.

This was based on the specific data chosen for review, which was informed by the selected organisation’s application of social-construct concepts. Considered from a national perspective, the study assumed that issues of biodiversity management concerns were not to be separated from everyday social realities and the larger social challenges. In view of this consideration, the study analysis looked at historical, political and socio-economic backdrops in Nigeria, which reflected on bioresource-use practises. These are relevant to understand the dynamics and interplay of culture and values in bioresource-use patterns. The study builds on diverse arrays of global frameworks to integrate the major findings of the study. These were compared with related and different dimensions as well as existing theories of human-bioresource interactions. The first aspect of the empirical analysis explored conceptual dimensions which raised questions concerning perceptions of reality and social values that were linked to the strategies of social-constructs expressed through policies, plans and practices. The study’s fundamental empirical dimension explored the forms in which programmes and social institutions were relevant in ensuring behaviour change towards sustainable bioresource-use practise. The analytical sequences observed trends which support facilitation of social change through behaviour change. Another aspect of the empirical analysis focused on revealing the processional dynamics of programme activities to achieve set objectives. This was analysed from the methodical perspective of how the processes were monitored and measured in order to achieve anticipated outcomes. The study summarised the findings and the outcomes by outlining the themes which emerged from the research. The study analysis argued that the ideals of social interventions cannot be different from a society’s inherent and attributed meanings to realities, as well as how they engage with their everyday realities.

- Description: Contact lens manufacture requires a high level of accuracy and surface integrity in the range of a few nanometres. Amidst numerous optical manufacturing techniques, single-point diamond turning is widely employed in the making of contact lenses due to its capability of producing optical surfaces of complex shapes and nanometric accuracy. For process optimisation, it is ideal to assess the effects of various conditions and also establish their relationships with the surface finish. Presently, there is little information available on the performance of single point diamond turning when machining contact lens polymers. Therefore, the research work undertaken herewith is aimed at testing known facts in contact lens diamond turning and investigating the performance of ultra-high precision manufacturing of contact lens polymers. Experimental tests were conducted on Roflufocon E, which is a commercially available contact lens polymer and on Precitech Nanoform Ultra-grind 250 precision machining. Tests were performed at varying cutting feeds, speed and depth of cut. Initial experimental tests investigated the influence of process factors affecting surface finish in the UHPM of lenses. The acquired data were statistically analysed using Response Surface Method (RSM) to create a model of the process. Subsequently, a model which uses Runge-Kutta’s fourth order non-linear finite series scheme was developed and adapted to deduce the force occurring at the tool tip. These forces were also statistically analysed and modelled to also predict the effects process factors have on cutting force. Further experimental tests were aimed at establishing the presence of the triboelectric wear phenomena occurring during polymer machining and identifying the most influential process factors. Results indicate that feed rate is a significant factor in the generation of high optical surface quality. In addition, the depth of cut was identified as a significant factor in the generation of low surface roughness in lenses. The influence some of these process factors had was notably linked to triboelectric effects. This tribological effect was generated from the continuous rubbing action of magnetised chips on the cutting tool. This further stresses the presence of high static charging during cutting. Moderately humid cutting conditions presented an adequate means for static charge control and displayed improved surface finishes. In all experimental tests, the feed rate was identified as the most significant factor within the range of cutting parameters employed. Hence, the results validated the fact that feed rate had a high influence in polymer machining. The work also established the relationship on how surface roughness of an optical lens responded to monitoring signals and parameters such as force, feed, speed and depth of cut during machining and it generated models for prediction of surface finishes and appropriate selection of parameters. Furthermore, the study provides a molecular simulation analysis for validating observed conditions occurring at the nanometric scale in polymer machining. This is novel in molecular polymer modelling. The outcome of this research has contributed significantly to the body of knowledge and has provided basic information in the area of precision manufacturing of optical components of high surface integrity such as contact lenses. The application of the research findings presented here cuts across various fields such as medicine, semi-conductors, aerospace, defence, telecom, lasers, instrumentation and life sciences.

- Description: This research is based on reflections of various practitioners and their views on how public participation processes may or may not contribute to effective EIA decisions. It is therefore grounded in what is described as practitioner-based research. To study comparative development activities effectively, one must draw on many disciplines and construct a balanced understanding of historical and contemporary development processes. No single conventional disciplinary area of research is able to integrate the issues of public participation, EIA and decision-making in the context of the current development debate. The emergence of Trans-disciplinary areas of research allows for such integration. The Africa Earth Observatory Network (AEON) institute creates the space for this study to achieve an integrated response to the question of the effectiveness of public participation in EIA and decision-making. This further creates the opportunity to contribute and expand the growing body of knowledge and literature of public participation in the earth stewardship science discipline. Making use of triangulation, this study fulfils four major tasks: firstly, an assessment is made on the historical and theoretical importance, process and outcome of both EIA and public participation internationally and in South Africa. Secondly, three prominent case studies (i) the Coega IDZ, (ii) the Pondoland N2 Toll Road, and (iii) the anticipated Hydraulic Fracturing in the Karoo each focusses on concerns of an environmental, socio-economic, and political nature to assess if the public participation process has had influence, if any, on the final decisions for these projects to go-ahead. Thirdly, a survey was conducted to establish the views and perceptions of practitioners in the EIA and public participation domain on the effectiveness of public participation in EIA processes. Lastly, face-to-face interviews were conducted with various ‘pracademics’, i.e. consultants, practitioners, government, and non-governmental officials to establish their views on how public participation may or may not influence EIA decisions. Utilising the International Association for Public Participation’s (IAP2) participation spectrum as an evaluation tool, this research explores thirteen key criteria normally attributed to effective public participation. This provides a scale (inform, involve, consult, collaborate) to assess whether public participation in EIA in South Africa is least effective (inform) or most effective (collaborate). My research confirms that in South Africa an enabling environment to address impacts on our environment is emerging. One of the main challenges remains putting in place robust, clear and effective regulations, models or approaches that provide for effective public participation and decision-making in EIAs. My research also suggests that the legislation on which EIA is based cannot by itself guarantee the effectiveness of public participation processes. In practice, EIA is an institutional process of power division between different actors, and the practitioner or ‘pracademic’ has to play a more fundamental role to ensure effectiveness and fairness in the public participation process. Academic commentators should therefore call for new approaches that emphasise collaborative interaction between decision-makers and the public as well as deliberation amongst participants.

- Description: The technological progress in terms of increasing computational power and growing virtual space to collect data offers great potential for businesses to benefit from data mining applications. Data mining can create a competitive advantage for corporations by discovering business relevant information, such as patterns, relationships, and rules. The role of the human user within the data mining process is crucial, which is why the research area of domain knowledge becomes increasingly important. This thesis investigates the impact of domain knowledge-driven variable derivation on classifier performance for corporate data mining. Domain knowledge is defined as methodological, data and business know-how. The thesis investigates the topic from a new perspective by shifting the focus from a one-sided approach, namely a purely analytic or purely theoretical approach towards a target group-oriented (researcher and practitioner) approach which puts the methodological aspect by means of a scientific guideline in the centre of the research. In order to ensure feasibility and practical relevance of the guideline, it is adapted and applied to the requirements of a practical business case. Thus, the thesis examines the topic from both perspectives, a theoretical and practical perspective. Therewith, it overcomes the limitation of a one-sided approach which mostly lacks practical relevance or generalisability of the results. The primary objective of this thesis is to provide a scientific guideline which should enable both practitioners and researchers to move forward the domain knowledge-driven research for variable derivation on a corporate basis. In the theoretical part, a broad overview of the main aspects which are necessary to undertake the research are given, such as the concept of domain knowledge, the data mining task of classification, variable derivation as a subtask of data preparation, and evaluation techniques. This part of the thesis refers to the methodological aspect of domain knowledge. In the practical part, a research design is developed for testing six hypotheses related to domain knowledge-driven variable derivation. The major contribution of the empirical study is concerned with testing the impact of domain knowledge on a real business data set compared to the impact of a standard and randomly derived data set. The business application of the research is a binary classification problem in the domain of an insurance business, which deals with the prediction of damages in legal expenses insurances. Domain knowledge is expressed through deriving the corporate variables by means of the business and data-driven constructive induction strategy. Six variable derivation steps are investigated: normalisation, instance relation, discretisation, categorical encoding, ratio, and multivariate mathematical function. The impact of the domain knowledge is examined by pairwise (with and without derived variables) performance comparisons for five classification techniques (decision trees, naive Bayes, logistic regression, artificial neural networks, k-nearest neighbours). The impact is measured by two classifier performance criteria: sensitivity and area under the ROC-curve (AUC). The McNemar significance test is used to verify the results. Based on the results, two hypotheses are clearly verified and accepted, three hypotheses are partly verified, and one hypothesis had to be rejected on the basis of the case study results. The thesis reveals a significant positive impact of domain knowledge-driven variable derivation on classifier performance for options of all six tested steps. Furthermore, the findings indicate that the classification technique influences the impact of the variable derivation steps, and the bundling of steps has a significant higher performance impact if the variables are derived by using domain knowledge (compared to a non-knowledge application). Finally, the research turns out that an empirical examination of the domain knowledge impact is very complex due to a high level of interaction between the selected research parameters (variable derivation step, classification technique, and performance criteria).

- Description: Music’s significant contribution to the holistic development of the young learner is uncontested and confirmed by views of seminal scholars, such as Nzewi 2003, Reimer 2003, Nussbaum 2001, Elliot 1994 and Merriam 1964, amongst others. As such, music education supports basic values of self-growth, self-knowledge and enjoyment. This study argues for the vital importance of music education in Grade R in the South African schooling system where teachers can successfully implement the curriculum. In post-apartheid multicultural and multi-musical South Africa music education in Grade R is the sole responsibility of the generalist Grade R teacher. However, due to inadequate training and minimal, unproductive in-service initiatives, the vast majority of Reception Year teachers assumingly do not have the required competences to teach music in a way that maximally enhances the holistic development of their learners. Findings revealed that teachers exhibited limited, if any, musical knowledge and per se, they are insufficiently skilled in the effective delivery of the curriculum in terms of music. This study acknowledges the need to equip in-service Grade R teachers with the required competences to effectively implement the national school and teach music with confidence. The lack of successful and effective continuing professional teacher development initiatives from the Department of Education and Department of Basic Education to assist Grade R teachers in teaching music, was a serious concern to me. This concern reinforced the motivation to embark on this project. In this thesis, I report on an intervention strategy aimed at enabling three Grade R practitioners at one peri- urban township school in the Eastern Cape to improve their music education competencies. These three Coloured ladies only held a Certificate in Early Childhood Development, rating at an NQF level 4 and 5. None of these practitioners had any prior music experience in music training, music making or music teaching. I utilised a Participatory Action Learning and Action Research (PALAR). PALAR combines research with development and is thus highly suitable when addressing multifaceted problems in rapidly changing environments, such as South Africa. In my study, the participants were thus actively involved in identifying problems and creating solutions. A number of collaborative interactions and qualitative data generation strategies such as Focus Group Interviews, Observations, Drawing, Interviews, Narrative Inquiry, Case Study and Reflective Journals were implemented. Findings indicated that the practitioners experienced transformation on both a professional and personal level as they discovered and tapped into their own innate musical competences. This enabled them to explore ways to teach music that enhanced the holistic development of their learners, developing them physically, cognitively emotionally, socially, and musically. Learners likewise benefitted from the intervention as they experienced social cohesion in a multicultural classroom and gained the fruits of music’s remedial impact and therapeutic value in their lives.

- Description: Critical care nursing is a clinical specialist nursing practice discipline. The critical care nurse provides a constant presence in the care of a critically ill patient. She/he creates a thread of continuity in care through the myriad of other health care professionals and activities that form part of a patient’s stay in the critical care environment (World Federation of Critical Care Nurses [WFCCN], 2007). During conversations with people who have had intimate experience of the critical care environment, they have offered anecdotes that describe their interaction with critical care nurses who they perceive to be different from and better than other critical care nurses they encountered. Despite having met common professional requirements to be registered as a clinical specialist nurse, these distinctive, unique abilities that seem to be influential in meeting the complex needs and expectations of critically ill patients, their significant others as well as nursing and medical colleagues, are not displayed by all critical care nurses. While students of accredited postgraduate nursing programmes are required to advance their nursing knowledge and skill competence, many students do not seem to develop other, perhaps more tacit, qualities that utilisers characterise in their anecdotes of ‘different and better’ nursing practice. The overarching research question guiding this study was how can ‘different and better’ critical care nursing practice as recognised by a utiliser be explained? The purpose of this study was to develop an understanding of the qualities that those people who use critical care nursing practice recognise as ‘different and better’ to the norm of nursing practice they encounter in this discipline. The participant sample included patients’ significant others, nursing colleagues and medical colleagues of critical care nurses, collectively identified as utilisers. The stated aim of this work was to construct a grounded theory to elucidate an understanding of the qualities that a utiliser of critical care nursing recognises as ‘different and better’ critical care nursing practice in order to enhance the teaching and learning encounters between nurse educators and postgraduate students in learning programmes aiming to develop clinical specialist nurses. The method processes of grounded theory are designed to reveal and confirm concepts from within the data as well as the connections between these concepts, supporting the researcher in crafting a substantive theory that is definitively grounded in the participants’ views and stories (Streubert & Carpenter, 2011: 123, 128-129). Two data collection tools were employed in this study, namely in-depth unstructured individual interviews and naïve sketch. Constant comparative analysis, memo-writing, theoretical sampling, theoretical sensitivity and theoretical saturation as fundamental methods of data generation in grounded theory were applied. The study unfolded through three broad parts, namely: Forming & shaping this grounded theory through exploration and co-creation; Assimilating & situating this grounded theory through understanding and enfolding; Reflecting on this grounded theory through contemplating and reconnecting. The outcome of the first part of the study was my initial proposition of a grounded theory co-created in the interactions between the participants and myself. This was then challenged, developed and assimilated through a focussed literature review through the second part of the study. Through these two parts of this study, an inductively derived explanation was formed and shaped to produce an assimilated and situated substantive grounded theory named Being at Ease. This grounded theory articulates how ‘better and different’ nursing is recognised from the point of view of those who use the nursing ability of critical care nurses through the core concern ‘being at ease’ and its four categories ‘knowing self’, ‘skilled being’, connecting with intention’ and’ anchoring’. The final part of this study unfolded in my reflections on what this grounded theory had revealed about nurses and elements of nursing practice that are important to a utiliser in recognising ‘different and better’ critical care nursing. I suggest that as nurses we need to develop a language that enables us to reveal with clarity these intangible and tacit elements recognised within the being and doing of ‘different and better’ nursing. I reflected on the pivotal space of influence a teacher has with a student, and on how the elements essential in being and doing ‘different and better’ nursing need to be evident in her/his own ways of being a teacher of nursing. Teaching and learning encounters may be enhanced through drawing what this theory has shown as necessary elements that shape ‘different and better’ nurses through the moments of influence a teacher has in each encounter with a student.

Two data collection tools were employed in this study, namely in-depth unstructured individual interviews and naïve sketch. Constant comparative analysis, memo-writing, theoretical sampling, theoretical sensitivity and theoretical saturation as fundamental methods of data generation in grounded theory were applied. The study unfolded through three broad parts, namely: Forming & shaping this grounded theory through exploration and co-creation; Assimilating & situating this grounded theory through understanding and enfolding; Reflecting on this grounded theory through contemplating and reconnecting. The outcome of the first part of the study was my initial proposition of a grounded theory co-created in the interactions between the participants and myself. This was then challenged, developed and assimilated through a focussed literature review through the second part of the study. Through these two parts of this study, an inductively derived explanation was formed and shaped to produce an assimilated and situated substantive grounded theory named Being at Ease. This grounded theory articulates how ‘better and different’ nursing is recognised from the point of view of those who use the nursing ability of critical care nurses through the core concern ‘being at ease’ and its four categories ‘knowing self’, ‘skilled being’, connecting with intention’ and’ anchoring’. The final part of this study unfolded in my reflections on what this grounded theory had revealed about nurses and elements of nursing practice that are important to a utiliser in recognising ‘different and better’ critical care nursing. I suggest that as nurses we need to develop a language that enables us to reveal with clarity these intangible and tacit elements recognised within the being and doing of ‘different and better’ nursing. I reflected on the pivotal space of influence a teacher has with a student, and on how the elements essential in being and doing ‘different and better’ nursing need to be evident in her/his own ways of being a teacher of nursing. Teaching and learning encounters may be enhanced through drawing what this theory has shown as necessary elements that shape ‘different and better’ nurses through the moments of influence a teacher has in each encounter with a student.

- Description: Tourism has come to be seen as a key driver for local economic development in South Africa, as it provides opportunities for pro-poor and community-based initiatives. On a global scale, the challenges of confronting poverty and unemployment continue to dominate the development agenda. The ability of Local Economic Development (LED) to empower local people has earned favour with national governments and development theorists. The imperative facing South Africa to achieve a more equitable and sustainable economy is essentially the challenge to adopt and implement a development approach that will reduce poverty and unemployment (which are the two key objectives of LED) to the greatest extent. It is within this context that the South African government has sought to incorporate LED into their economic development framework, predominantly through the decentralisation of development control and planning to the local government level. This study examined the contribution of guest houses to economic growth and employment as key components of LED in a sustainable manner. The study revealed that guest houses are playing a key role in the development of the local economy in the Eden district region. Guest houses are providing employment opportunities to the local residents both on a full-time and part-time basis. Further to this, guest houses are buying many locally-produced products and services from local suppliers and this contributes to economic growth of the local economy. However, this study also found that many of the guest houses in the area are not aware of government incentives available to support them and very few of them have made use of these services. This is something that needs to be addressed if these guest houses are to continue to strengthen the local economy and provide employment opportunities in a sustainable manner. The study revealed that many of the guest houses are operating in an environmentally friendly manner and this will ensure their future sustainability. The broader situation and the contribution of the accommodation sector as critical assets in local and national tourism economies has been thoroughly researched in tourism research around the world. Existing work on the accommodation sector in the South African tourism economy is mainly urban-focused and indicates that its local development impacts can be positive albeit not always maximised through local linkages, however, only a limited amount of academic investigations examines the contribution of tourism sub-sectors to economic growth and employment. The authenticity of this study is based on Its contribution which must be viewed in relation to the relatively limited body of literature in the contribution of tourism sub-sectors to economic growth and employment and in this case guest houses as one type of accommodation sub-sector.

- Description: Approximately sixty percent of Africans depend on rainfed agriculture for their livelihoods. South Africa is evidenced to be susceptible to inclement climate which impacts on rural livelihoods as well as on farming systems. While South Africa is considered to be food sufficient, it is estimated that approximately 35% of the population is vulnerable to food insecurity. Therefore with the application of surveys and interviews this study investigates the factors influencing household, subsistence and small-scale farmer perceptions of vulnerability to climate variability as well as the determinants of adaptive capacity. A sample of 308 households is surveyed and four focus group discussions are administered in Ngqushwa Local Municipality as a case study. Furthermore, the study also focuses on the biophysical changes or factors (scientific analysis of the prevailing climatic regimes–rainfall trends); the interrogation of the impact of food systems on both food prices as well as its implications on food sovereignty. The study also interrogates the relationship between crop yield and rainfall data over a 30-year period. Therefore the study adopts a mixed method approach to ensure triangulation. The study finds that rural communities are able to perceive climate variability and its related changes as well as its negative impact on crop production, food access and availability. The perceived rainfall trends also corroborate this Pearson product-moment correlation coefficient reveals that there is a strong correlation between crop yields and rainfall (r = 0.69). Meteorological analyses also show that the rainfall trend has been significantly variable over 112 years (1900 - 2011) with several dry spells threatening the subsistence and small-scale farmers’ sustainable livelihoods. The food systems pose threats to food safety, food security and historical food sovereignty for the rural community of Ngqushwa Local Municipality. Adaptive capacity is greatly impaired by the lack of co-ordination of adaptation strategies, which communally benefit the majority of the farming respondents in the study area. Therefore vulnerability to climate variability impacts on the ability of the respondents to achieve food security. The study also finds that there is perceived competition between the farmers and wild life for the natural resources. The respondents’ perception is that climate variability and change is responsible for such competition. The study recommends that the national, provincial and local governments must foster a new food production model that is not based on the agro-business model and its attendant technologies but on one that is based on robust agro-ecological farming techniques which enhance adaptive capacity; which foster food safety; which promote food sovereignty; and which reduce vulnerability in a sustainable manner. Given the extent of climate variability in the study area the restoration of the NLM weather station infrastructure can also aid the farmers in taking advantage of a robust early warning system for better estimation of climate trends which enhance crop production.

- Description: Cloud computing adoption and usage is important to achieving business competition. This is done by making it a competitive tool for firms. The adoption of cloud computing enables firms to achieve greater business competency, improve performance, and allows them to maintain their competitive advantage. Since its emergence, there has been a surge in the adoption of cloud computing with research into its adoption primarily concentrated on bigger firms. However, a major characteristic of cloud computing is the anticipated possibilities it holds for small and medium-sized enterprises (SMEs). SMEs typically operate differently from larger firms and are not limited by resource constraints. For SMEs, the reduction in the financial burden normally associated with the adoption of new technologies is a significant benefit of cloud computing due to their financial constraints. In Ghana, SMEs mostly use obsolete technologies and have a slow response towards new technologies. Thus, they are unable to harness the numerous opportunities technology presents to them to stay competitive. Cloud computing is still regarded as a new technology in the business world, therefore research that focuses on its adoption by SMEs to help them stay competitive is minimal. Available research on cloud computing in Ghana does not provide clear guidelines for ensuring a successful adoption process and the continued use of cloud computing services. This study seeks to investigate how a framework can assist SMEs in their use of cloud computing in the Accra-Tema metropolis of Ghana. A knowledge of the factors associated with adoption decisions and those that significantly influence the decision are required to ensure a successful adoption process. The empirical data was gathered using a questionnaire and face-to-face interviews developed from literature and administered to users and potential users of cloud computing. The questionnaire and interviews primarily investigate key adoption factors and the findings are reported in this research study. The findings reveal interesting insights into understanding issues that affect the overall decision to adopt and use cloud computing services by SMEs. The findings show that the adoption of cloud computing can improve information management practices within SMEs. The findings also reveal that several factors need to be considered in the overall decision to adopt and use cloud computing to ensure a successful adoption process. An initial cloud computing adoption model was proposed based on the empirical findings. Key adoption factors of the initial adoption model include adoption benefits and drivers, concerns and barriers, adoption interventions, and information management in the cloud. computing adoption framework. The proposed adoption framework aims to assist SMEs to adopt and use cloud computing services and make them relevant in the global market.

Whither South Africa – neoliberalism or an embodied communitarian indigenous ethic?

- Description: This thesis offers a critique of neoliberal transformation in South Africa, which process results in growing social inequality and political apathy among citizens. Many scholars have made political-economic and historical analyses of the neoliberal transition, emphasizing structural changes at work at a ‘macro’ level. However, little attention has been paid to changes that have taken place in South Africa at the ‘micro’ level – changes to individual subjectivity and gender codes. That said, the thesis opens by summarizing the above mentioned political-economic accounts of neoliberalism in South Africa, because such works are indispensable to understanding how the regime is embedded within and buttressed by major global institutions. Yet, to achieve a holistic grasp of ‘neoliberal South Africa,’ more is needed. A sociological investigation into the impact of neoliberalism on ordinary people’s self-identification uncovers deep cultural reasons for the continued perpetuation of this unjust political-economic system. Only if it can be understood why people comply with the system in the face of suffering, can effective counter-measures be proposed and implemented over time. This thesis is inherently transdisciplinary. The approach rejects the privileging of one discipline over others, and likewise cautions against collapsing or dissolving disciplines into one another. Instead, recognizing the valuable contribution that each discipline can make to critical scrutiny of a particular issue, a form of methodological transversalism is used to bring different disciplines into dialogue with one another. Following this interplay of structural and subjective analysis, the thesis uncovers the role that consumerism plays in the political neutralization of South Africans. Consumer culture, tied as it is to profitable accumulation, instigates the neoliberal ‘values’ of economistic calculation, competition, and social atomization. This ethos is inculcated in individuals, both at work and during leisure hours. Moreover, consumerism derives much of its power from its ‘sexual sell,’ the creation of fashionable and ‘exemplary’ models of masculinity and femininity. In South Africa, these hegemonic gender models serve to instill competitive individualism while derogating indigenous values. The thesis proposes that in order to counter neoliberal hegemony in South Africa, and begin reclaiming the cultural autonomy of its peoples, it is important to invigorate indigenous communitarian practices and norms. The original contribution of this thesis consists in placing the African ethos of ubuntu in transversal dialogue with global ecological feminist voices. Both political perspectives reinforce a liberatory alternative vision for a future based on principles of embodied relationality, care giving and protection of community.

- Description: Researchers have described human trafficking as a complex, multi-layered crime. South Africa, including the Eastern Cape Province, is a source, transit, and destination country for trafficked people. However, a dearth of research on human trafficking exists in the province. Furthermore, traditional, modernist research using reductionist methods to investigate complex phenomena has proven unable to capture the complex interrelationships between the myriad of interrelated elements inherent in complex phenomena. In this qualitative study, I explore and describe the human trafficking system in the Eastern Cape via participants’ perspectives through a complex systems approach that consists of two complementary theories, namely Bronfenbrenner’s bioecological theory of human development and complexity theory. The participants, who were knowledgeable about human trafficking in the province, were obtained through purposive and snowball sampling. Data collection took place through open-ended interviews with individual participants. I analysed the data according to Miles and Huberman’s data analysis process and Braun and Clarke’s thematic data analysis process. The findings demonstrate that the complex systems approach successfully facilitated the mapping and conceptualisation of an in-depth, multi-level picture of the complex interrelationships within and between multiple system components in the human trafficking system and its environment in relation to the Eastern Cape Province. Participants’ perspectives revealed two main themes, namely, the prominence of the nonlinear interactions between traffickers and trafficked persons in the holistic human trafficking system and the major obstacle regarding the lack of witness credibility for human trafficking prosecutions to be successful. Utilising complex systems theory to conduct further human trafficking research could assist counter-trafficking stakeholders with an alternative approach to generating effective planning and executing counter human trafficking strategies in a rapidly changing and increasing complex interconnected world.

- Description: The goal of mental health delivery system is to allow the individual with severe and persistent mental illness to live and function effectively in the community and to ensure that the consumers and their families have access to accurate information that promotes learning, self-monitoring and accountability (Stuart & Laraia, 2005:710). In community-based health care, the persons living with severe and persistent mental illness (SPMI) are in their natural environment in the context of the family and the community. The goals of care are focused around maximizing the person living with SPMI’s quality of life (Hunt, 2001:15-16). In South Africa, an integrated package of essential Primary Health Care (PHC) services has been made available to the entire population in order to provide the solid foundation of a single unified health care service (Department of Health, 2000:4). The assessment of health care needs of persons living with SPMI is a dynamic on-going process that is used to collect information, recognise changes, analyse needs and plan health care to provide baseline information to help evaluate the physiological and psychological normality and functional capacity of persons with SPMI (Hunt, 2001:100). There is insufficient information from the Department of Health to either satisfy the enquiry of whether the health care needs of persons living with SPMI are being met comprehensively or whether the practitioners rendering community-based health care are knowledgeable and comply with PHC norms and standards developed by this Department. The researcher is interested in understanding how the persons living with SPMI and their families experience the community-based health care provided by PHC nurses. The purpose of this research study is to develop strategies that would assist the PHC nurses in the selected rural areas of the Eastern Cape to facilitate community-based health care and to render a health care service relevant to the health care needs of the persons living with SPMI and their families. To achieve the objective of the study, the research design was based on a qualitative, exploratory, descriptive, contextual research approach. Phase one includes describing and selecting the research population and the sampling process prior to conducting the field work which comprises individual interviews with persons living with SPMI and their families as well as PHC nurses. According to Dickoff, James and Weidenbach (1968:422) and Chinn and Kramer (1995:78), this strategy involves identifying concepts from fieldwork and creating conceptual meaning to provide a foundation for developing strategies to facilitate community-based care for persons living with mental illness. Phase two of the research design will focus on development of conceptual framework in order to allow better understanding of the phenomenon of interest, as the major concepts will be simplified by connecting all related concepts together by means of statements. This was done by making use of the themes identified during data analysis and the literature sources used throughout this research process. The evaluation criteria of Chinn and Kramer (2008:237-248) were used to evaluate the strategies. It is therefore concluded that the researcher succeeded in achieving the purpose of this study because strategies which were understandable, clear, applicable and relevant to the nursing practice have been developed for use by Department of Health and Primary Health Care to facilitate the multifaceted role of the PHC nurses.

Phase one includes describing and selecting the research population and the sampling process prior to conducting the field work which comprises individual interviews with persons living with SPMI and their families as well as PHC nurses. According to Dickoff, James and Weidenbach (1968:422) and Chinn and Kramer (1995:78), this strategy involves identifying concepts from fieldwork and creating conceptual meaning to provide a foundation for developing strategies to facilitate community-based care for persons living with mental illness. Phase two of the research design will focus on development of conceptual framework in order to allow better understanding of the phenomenon of interest, as the major concepts will be simplified by connecting all related concepts together by means of statements. This was done by making use of the themes identified during data analysis and the literature sources used throughout this research process. The evaluation criteria of Chinn and Kramer (2008:237-248) were used to evaluate the strategies. It is therefore concluded that the researcher succeeded in achieving the purpose of this study because strategies which were understandable, clear, applicable and relevant to the nursing practice have been developed for use by Department of Health and Primary Health Care to facilitate the multifaceted role of the PHC nurses.

- Description: In view of the important role that small businesses play in the economic development of most economies in the world, including South Africa (Adeniran & Johnston, 2012:4088; Kongolo, 2010:2290), as well as the survival challenges that they face, the purpose of this study was to propose a framework for effective mentoring. This framework can be used to develop the business management skills of black small business owner–managers which will eventually increase the survival of small businesses in South Africa. As such, the primary objective of this study was to gain an understanding of the conditions required for effective mentoring of black-owned small businesses by empirically identifying the factors that influence effective mentoring of these businesses. If mentoring programmes for black-owned small businesses can be effective, the high failure rate of these businesses could be reduced, which may influence the South African economy positively. This study sought to review previous findings and theories on mentoring and small business development, and then contextualise these to black-owned small businesses. A comprehensive literature review revealed potential factors which could influence the effectiveness of mentoring of black-owned small businesses. Four categories of these factors were identified, namely relational-based, non-relational based, cultural and demographical factors. These factors guided the collection of primary data in this study.

- Description: The primary objective of this thesis was to investigate whether intrinsic rewards play a role in the intrinsic motivation, work engagement and retention of employees working within non-profit organisations in Australia, Belgium, South Africa and the United States of America. It therefore served to form a cross-cultural comparison between employees from these four geographically dispersed yet culturally similar countries. A further aim was to determine whether demographic differences occurred across the four constructs studied. In order to achieve these objectives, a theoretical model was constructed to highlight the relationships between the constructs under study. The study made use of both qualitative and quantitative research to achieve the above-mentioned objectives. As a result of the data obtained from 15 qualitative interviews conducted with non-profit employees in Belgium and South Africa, two measuring instruments, namely the Intrinsic Work Rewards Scale and the Intrinsic Work Motivation Scale, were developed to assess intrinsic rewards and intrinsic motivation respectively. These measuring instruments were qualitatively piloted on a sample of academics and non-profit employees, and were translated from English into Dutch for use on the Belgian sample. Once these instruments had been refined, they were combined with instruments to measure work engagement and intention to quit to form a composite questionnaire. This questionnaire was completed electronically by 587 non-profit employees from the four countries under study. Data analysis was conducted in the form of descriptive and inferential statistics, including frequency tables, Cronbach’s alpha testing, exploratory and confirmatory factor analysis, Pearson’s Product Moment Correlations, chi-square tests, t-tests, analysis of variance and structural equation modelling. The quantitative findings showed that intrinsic rewards lead to higher levels of intrinsic motivation, which in turn causes higher levels of work engagement and lower levels of intention to quit. Intrinsic rewards were also found directly to predict a reduction in employees’ intentions to quit their non-profit organisations, and work engagement directly predicted an increase in intention to quit. From a cross-cultural perspective, practically significant inter-country differences were discovered across the intrinsic rewards of meaningful work and challenging work; across intrinsic motivation and its three dimensions (personal connection to one’s work, personal desire to make a difference, and personal desire to perform); and across work engagement and its three factors (absorption, dedication and vigour). In addition to these inter-country results, age and job level differences were discovered across the four constructs under study, together with significant correlations between the four constructs. The Intrinsic Work Rewards Scale and the Intrinsic Work Motivation Scale were successfully validated in both English and Dutch in this study, with a number of forms of validity being confirmed through factor analyses and correlations. Reliability was proven through satisfactory Cronbach’s alpha values being obtained for both language versions of the instruments. These results theoretically contribute to literature pertaining to intrinsic rewards and intrinsic motivation as a result of the development of two measuring instruments that were empirically validated to assess these constructs. Furthermore, the results make a valuable contribution to the field of rewards management globally. This study’s findings provide evidence for causal relationships between four constructs not previously tested empirically, specifically within Australia, Belgium, South Africa and the United States of America. Consequently, this study’s results hold important implications for the management of non-profit employees worldwide.

- Description: The purpose of this study is to investigate the relationship between outsourcing and development in Nairobi. The key research question for this study is what are the impacts of outsourcing practices conducted by organisations in Nairobi? Data were obtained from questionnaires distributed in December 2010. A total of 85 profit-making firms in Nairobi with a sample of 165 management employees were selected for this study. The empirical findings obtained relate to four outsourcing theories. Transaction Cost Analysis (TCA) Theory focuses on the cost savings that result from outsourcing. Agency Outsourcing Theory centres on outsourcing firms hiring agents to achieve productivity. Hiring agents may result in permanent staff being retrenched and additional outsourcing personnel being contracted and job creation and/or job loss results. Expectation Confirmation Theory (ECT) emphasises the importance of an outsourcing provider conforming to quality management principles. Resource Based Theory (RBT) proposes that organisations need a collection of resources and capabilities to execute outsourcing successfully. Findings further suggested that outsourcing can yield positive and/or negative outcomes depending on risks encountered, the business environment, company policies, function/s to be outsourced, and the competence and commitment of an outsourcing vendor. To further enhance the positive impact of outsourcing three improvements need to be executed: formulation of standard policies, price regulations, and commitment of outsourcing firms in adhering to set contract deadlines. It is suggested that the following would allow organisations to gain more from outsourcing in the future: the adoption of international/offshore outsourcing practices, more commitment by outsourcing consultants, the standardisation of charges for outsourcing contracts, and the use of new technology that would improve how outsourcing is conducted. It is concluded that the positive impacts of outsourcing would foster development to some extent while the possible negative impact of outsourcing would impede development.
