- Description: In an ever-changing environment, it has become difficult for organisation to create and maintain a competitive advantage. Nowhere is it more evident than in the manufacturing industry. For organisations to be successful, it is imperative for them to have a clear and well-defined strategy. This strategy should be viewed as the steering mechanism of the organisation. With the ever-increasing demands of customers, organisations have been forced to be agile in order to adapt to sudden changes. Now more than ever, technology can be used as a powerful tool. For organisations to be profitable and grow, they need to have a management team that is competent to manage the organisation in turbulent times. To ensure a competitive advantage, management must be able to predict the future needs of the organisation. The use of technology forecasting and technology audits can assist management in addressing this process. Most organisations are technology intensive and deliver products or services. The research attempts to determine a strategy for the successful implementation and management of technology in a manufacturing organisation. It also tries to establish the impact of technology auditing on the competitive advantage of the organisation. A comprehensive technological audit questionnaire was used in conducting an audit at Valor Fruit Processors (Pty) Ltd. It must be emphasised that this model is a generic model and should be customised to suit each particular organisation.

- Type: Thesis , Doctoral , DTech (Science)

- Description: The project was concerned with the investigation of the electrochemical oxidation of various phenols, and to develop a viable reaction system for the production of the respective hydroquinones. Current production routes utilizing phenol as starting material have the limitations of using large amounts of acids, having to be stopped at low conversions and producing a mixture of the hydroquinones and catechols. Of the possible routes to the respective hydroquinones from the various phenols, the electrochemical oxidation of these phenols offers commercial and environmental advantages and hence formed the theme of the investigation. The synthetic possibilities proved to be more prevalent in a system when the electrochemical oxidation of these phenols was performed in an aqueous medium utilizing an organic co-solvent. Results obtained during this investigation made it possible to make certain predications about the mechanism taking place. This was found to depend on the anode material used for the oxidation. The results showed that the process developed for the electrochemical oxidation of these phenols, yields mainly the para-isomers of the respective hydroquinones and benzoquinones in good yields and selectivities, with fair current efficiencies and good mass balances at high conversions. For example: * Phenol (batch) 8 F: 345% current efficiency, 70% hydroquinone, 6% catechol, 9% benzoquinone, 9% phenol and 94 mass balance. * 2-Tert-butylphenol (flow) 10 F: 37% current efficiency, 65% hydroquinone, 33% benzoquinone, 2% phenol and 100% mass balance. * 2,6-Di-tert-butylphenol (flow) 11 F: 23% current efficiency, 92 % hydroquinone, 6% benzoquinone, 1% phenol and 99% mass balance. The developed electrochemical oxidation system offers the following advantages over previous and current methods: simplified isolation and extraction procedures, smaller amounts of acid usage, reasonably selective synthesis of the para-isomer and a less corrosive system all at high conversions.

- Description: Health and safety management forms part of the overall risk management of medical institutions, and deals with the responsibility of an organisation to provide a risk free environment for all who are exposed to the activities of such medical institutions. Affected people include health care workers, contractors, visitors, and patients. Medical institutions, and hospitals specifically, are uniquely distinct from other industries in that they employ highly skilled staff with specific specialised knowledge. These institutions are also increasingly making use of complex technology that requires specialist staff to operate medical machines and equipment. These specific aspects are accounted for in this research. The overall purpose of this research is to determine the need for an alternative approach to the management of health and safety in medical institutions. An appropriate model will be developed that can be integrated into the existing health and safety management system. The research methodology for this study comprises the following steps: Firstly, the health and safety environment was researched in relation to all stakeholders, external and internal, that are affected by medical institutions’ activities. The effect of these activities, and how it influences health and safety management, was evaluated in a South African context. Secondly, the overall risk management approach of medical institutions and the effect of organisational culture were researched to determine the effect on health and safety performance. Thirdly, a questionnaire was sent to selected staff of five hospitals in the Eastern and Western Cape to determine their perception and experience of health and safety management. Quantitative data on incidents in Netcare Hospitals were obtained, and a comparison of the questionnaire studies was done to determine the need for a health and safety model. The final step of this study entailed the development of a health and safety model using legislative requirements and the needs identified in the research. A proposal is made to integrate specialist functions and departments into the existing health and safety management system, in order to strengthen the managerial capabilities of such a system. The importance of improving the safety and compliance culture is indicated.

- Description: The research problem in this study was to identify best practices for the contingency management of health-related absenteeism. To achieve this goal, the following actions were taken: A literature study was conducted to identify the scope and impact of health-related absenteeism on organisations and the legal parameters within which health-related absenteeism should be managed. A literature study was also conducted to identify strategies to prevent and reduce health-related absenteeism and strategies to ensure the continuous provision of products and services in periods of high absenteeism. The theoretical study focused on the management of absenteeism, wellness, ill-health/mental problems and HIV/AIDS, as well as contingency strategies aimed at maintaining production and service provision. iii The findings from the literature study were integrated into a model of best practices for the contingency management of health-related absenteeism. This model was used as a basis for the development of a survey questionnaire to determine whether senior human resources practitioners, occupational health practitioners or line managers, who were responsible for the management of health-related absenteeism in organisations, agreed with the best practice guidelines developed in the study. The survey was conducted in the motor and motor component industry in the Nelson Mandela Metropolitan Municipality and Buffalo City Metropole. The empirical results from the study showed a strong concurrence with the best practices guidelines developed in the study, with the exception of the strategies aimed at maintaining undisrupted production and service provision during periods of high absenteeism. In particular, disagreement was shown with regard to alternative work arrangements such as flexible work-hours, a compressed workweek, telecommuting and job-sharing. Absenteeism, in general, is an issue that organisations are challenged with on a daily basis. The proliferation of various diseases, specifically HIV/AIDS, is contributing to this problem. An integrated and strategic approach is required to deal effectively and constructively with the immediate and expected future impact of health-related issues on absenteeism. Organisations could use the best practices guidelines, identified in this study, as a mechanism to benchmark how well they manage health-related absenteeism

- Description: The purpose of this study was to develop motivational strategies for motivating public sector workers in Kenya. To achieve this objective the following procedure was followed: • An examination of the public service was undertaken and the following factors were considered: The history of the public service; Past government reform programmes; The problem of corruption; Future government reform programmes; and The motivational climate in the service. iv • A literature survey was conducted on the approaches used by organisations in motivating employees. The findings were used to develop a motivational strategy model. On the basis of the strategies in the model, a questionnaire was developed for the empirical research study. • The empirical study was undertaken to examine the level of motivation in the public service and to identify the motivational strategies currently used in the public service in Kenya. The study also sought to determine the extent to which public sector managers agreed or disagreed that the motivational strategies developed by the study would be effective in motivating employees in their organisations. The results of the empirical study were incorporated into the integrated motivational strategy model presented in chapter six. The study established that the level of motivation among the public sector workers was extremely low. According to the research findings, 87 per cent of the respondents indicated that the level of motivation of employees in their organisation was low while 13 per cent indicated that it was high. It was also established that the climate in the public service was not conducive for motivating employees: the indicators were lack of job security; very low salaries; limited training and development opportunities; lack of career development programmes and lack of adequate working tools and equipment. It was further established that the government could no longer afford to make any substantial increases in salaries to the workers because the wage bill was extremely high at the level of 9.6 per cent of the GDP. It was observed that any further increases in salaries would v have a negative impact on the economy of the country. In view of the above, this study becomes extremely relevant as it suggests ways of enhancing the levels of motivation in the public service to improve service delivery in the public sector without allocation of vast financial resources. The study strongly recommends the application of the integrated motivational strategy model in its entirety; to enhance the level of employee’s motivation and work performance and achieve efficiency and effectiveness in service delivery. The study also recommends that further research be carried out to determine the effects of corruption on employee motivation and ways of eliminating the vice in the public service.

- Description: South African organisations are facing a new era of intense global competition. The modern business world is characterised by change and this change presents both challenges and opportunities. As a result, organisations have to become more responsive to change by continuous, rapid and cost-effective innovation through integrating the strengths of the entrepreneurial small firm, such as creativity, flexibility and innovativeness, with the market power and resources of the large firm. Due to the dynamic nature of the automotive industry, it is vital that South African organisations and management identify creativity and innovation as the main sources of sustainable competitive advantage. Sustained competitive advantage is derived from consistently satisfying customers’ wants and needs through innovation. An intrapreneurial philosophy is of key importance to an organisation’s corporate strategy, ensuring that entrepreneurial values are incorporated into the culture of the organisation. This study took place within an automotive component company operating in the Eastern Cape. Based on the theoretical findings of the literature study a questionnaire was developed and distributed to all employees of the company. The objective of the questionnaire was to measure the prevalence of intrapreneurship within the company and based on the findings of the literature study, recommendations on the structure, systems, culture and management styles of the organisation were made. Finally, a model was developed that identifies the importance of innovation, customer-solution centeredness and being market driven as core strategic values.

- Description: There has been a shift in the South African education system from a purely grade-oriented system to that of a learner-centred outcome-based system of education which challenges higher educational institutions and their faculties to adjust their goals to this system. In South Africa there is evidence of poor academic performance at higher education institutions. Among other things, noncognitive factors may be important mediators of academic success. With the expansion of higher education and the increased emphasis on access, retention and life-long learning, it is a good reason to explore the nature of different learning styles (Healey & Jenkins, 2000). Learning styles and personality types has been identified as significant predictors of academic performance. The present study aimed to contribute to this body of research in general and to Kolb’s (1981) theory of experiential learning and his conceptualisation of learning styles in particular. The aims of the study were to explore and describe the learning styles of first year university students (Aim 1), to explore and describe the learning styles of first year university students per faculty (Aim 2), and to explore the relationship between learning styles and academic performance for students in the various faculties (Aim 3). The study used an explorative descriptive and correlational research method and was conducted within a quantitative framework. Participants were selected using a non-probability convenience sampling technique. The sample was comprised of 391 first year university students to whom Kolb’s Learning Style Indicator was administered as part of the Explore programme during orientation week. Descriptive statistics were used in order to explore and describe the learning style of the learners for the sample as a whole and per faculty. Data for the learning styles and academic performance categories were cross tabulated so as to comment on the relationship between learning styles and academic performance per faculty. Small cell sizes made it impossible to analyse the latter data statistically. Across the six faculties the Accommodator learning style was the most represented, followed by the Diverger learning style. No significant relationship was found between learning styles and academic performance. The implications of the findings for counselling and teaching students are highlighted and suggestions to expand the research through using larger samples are also made.

- Description: Many network monitoring tools do not provide sufficiently in-depth and useful reports on network usage, particularly in the domain of application services data. The optimisation of network performance is only possible if the networks are monitored effectively. Techniques that identify patterns of network usage can assist in the successful monitoring of network performance. The main goal of this research was to propose a model to mine and visualise application services data in order to support effective network management. To demonstrate the effectiveness of the model, a prototype, called NetPatterns, was developed using data for the Integrated Tertiary Software (ITS) application service collected by a network monitoring tool on the NMMU South Campus network. Three data mining algorithms for application services data were identified for the proposed model. The data mining algorithms used are classification (decision tree), clustering (K-Means) and association (correlation). Classifying application services data serves to categorise combinations of network attributes to highlight areas of poor network performance. The clustering of network attributes serves to indicate sparse and dense regions within the application services data. Association indicates the existence of any interesting relationships between different network attributes. Three visualisation techniques were selected to visualise the results of the data mining algorithms. The visualisation techniques selected were the organisation chart, bubble chart and scatterplots. Colour and a variety of other visual cues are used to complement the selected visualisation techniques. The effectiveness and usefulness of NetPatterns was determined by means of user testing. The results of the evaluation clearly show that the participants were highly satisfied with the visualisation of network usage presented by NetPatterns. All participants successfully completed the prescribed tasks and indicated that NetPatterns is a useful tool for the analysis of network usage patterns.

- Description: The oxidative coupling of 2,6-di-t-butylphenol under mild reaction conditions is well documented and the subject of many patents. However, the coupling of other monoand di- substituted phenols is not as well documented and thus there is scope for further investigation for providing a convenient, environmentally friendly and economically viable method for the oxidative coupling of these phenols. In this study, the oxidative coupling of a variety of alkylated phenolic substrates, 2-tbutylphenol, 2,6-di-t-butylphenol, 2,4 -di-t-butylphenol and ,4-dimethylphenol, using a range of different oxidizing agents, were investigated by means of experimental and/or theoretical means. The dibutylated aromatics provided the highest selectivities to their respective coupled products, with results obtained with the dimethyl analogue being only satisfactory, and that for 2 -t-butylphenol being totally inefficient. PM3 Molecular orbital (MO) calculations were used to predict the possible modes of coupling for the substrates 2,6 -di-t-butylphenol and 2,4-di-t-butylphenol, and these results were then compared with those obtained experimentally in the laboratory. Preliminarily, the coupling of unsubstituted phenolics was also assessed by means of MO calculations. Much emphasis was placed on Ce(IV) as the oxidant, and the reaction conditions under which it was used and the results that were obtained have not been reported before and are therefore novel. The oxidation of 2,4-di-t-butylphenol using Ce(IV) in the presence of methanesulphonic acid was optimized to afford high yields and selectivities to the desired ortho C-ortho C coupled product under mild reaction conditions. Various reaction parameters were also investigated in this case, such as varying the MeSO3H concentration, the solvent, the reaction temperature, the reaction time, the substrate loading, the rate of oxidant addition and the substrate to oxidant ratio. Ce(IV) also gave a high selectivity to the para C-para C coupled product when IX using 2,6-di-t-butylphenol as the substrate. However, it was not as effective with 2,4- dimethylphenol, and even less so with 2-t-butylphenol. The oxidation reactions of 2-t-butylphenol and 2,4-dimethylphenol with various coupling agents were also investigated with the intention of obtaining high selectivities to the respective desired coupled products. In these studies, 2-t-butylphenol afforded a large number of products, irrespective of the oxidant used. The dimethyl analogue was more selective, but results were not optimal. It was clear that the number of substituents on the phenol ring, their nature and their position with regards to the hydroxyl moiety was of great importance and made a significant impact on the preferred coupling mode of the substrate. It was observed that steric effects also played a major role in the outcome of these reactions: 2,6-di-t-butylphenol never afforded any C-O coupled products whereas 2-t-butylphenol, 2,4-di-t-butylphenol and 2,4-dimethylphenol all appeared to undergo some C-O coupling. Finally, reaction mechanisms were provided for both the K3Fe(CN)6 and Ce(IV) work, these reacting in basic and acidic media, respectively. It was proposed that both of these mechanisms operate through the initial formation of the phenoxyl radical.

- Description: Worldwide millions of children are victims of neglect and physical and mental harm, including sexual abuse and exploitation. South Africa, however, is widely believed to have not only one of the highest incidences of rape in the world, but also one of the highest levels of Human Immunodeficiency Virus (HIV)/Acquired Immune Deficiency Syndrome (AIDS) transmission. With research findings showing that HIV and other Sexually Transmitted Infections (STIs) are rapidly increasing globally, young people are, and continue to be, at the forefront of the AIDS pandemic. Therefore, it is suggested that prevention programmes should be aimed particularly at the young. Schools have specifically been recognized as the setting for preventative Life Skills Programmes, having the potential to reach billions of children worldwide. The aim of this study is to explore and describe the perceptions of grade eight and nine learners with regard to the Life Skills Programme that focuses on HIV/AIDS and STI's, rape and child abuse education in the Port Elizabeth region. In order to fulfil the above aim, a qualitative study was undertaken within an exploratory descriptive approach. A non-probability sample of four schools was selected. Focus groups, utilising an unstructured interview, were used to gather qualitative data on the learners' perceptions of the Life Skills Programme. The focus groups consisted of 10 - 12 grade eight and nine learners who were selected using simple random sampling. The data was thematically analysed using Tesch's approach. The major findings of the present study, based on the six general themes, include the following: 1. Most of the learners perceived the educators, as well as the teaching methods utilised by the educators, positively. 2. Although the learners perceived the presenters of the Life Skills Programme positively, it was suggested that teachers, health care professionals, family members and peers should be involved in presenting the Life Skills Programme. 3. Learners reported various levels of comfort discussing different topics presented in the Life Skills Programme. 4. Learners of all the schools perceived the Life Skills Programme to be very relevant. 5. Learners recommended that more children, especially children from deprived communities, should be included in the programme. In addition, learners felt that counselling services should be available in conjunction with the Life Skills Programme. 6. Differences were noted in completing the first and the second questionnaire. Learners reported that they felt more comfortable completing the second questionnaire. They perceived the interviewing process positively.

- Description: Research has shown that Attention Deficit Hyperactivity Disorder (ADHD) is one of the commonest neurodevelopmental disorders which has a negative impact on a child. However, to date limited research has been conducted on learners, and specifically those learners with ADHD, within a National Education stream. Furthermore, running concurrently with this are new developments in education in South Africa. An inclusive educational policy favours the incorporation of all children into a mainstream scholastic setting, regardless of their diverse needs. In addition to educational changes for children with ADHD, many parents are presently unable to afford the medication commonly used to treat the disorder, resulting in both parents and teachers having to manage these children with limited professional support. It is widely accepted that early assessment and intervention are necessary in order to maximise a child’s potential. For this reason, the primary aim of this study was to explore and describe the developmental profile of children with ADHD on the Griffiths Mental Development Scales-Extended Revised (GMDS-ER). Further aims were to compare the performance of the clinical sample to a normal South African sample. In order to achieve these aims, a quantitative, exploratory-descriptive research design was employed. The sample (N = 38) of ADHD were selected by means of a non-probability, purposive sampling procedure, from various pre-school and primary schools in the Nelson Mandela Metropole. The normal sample (N = 38) was drawn from an existing database created during the revision of the Scales. Information was collated using the Conners 39 Item Teacher Rating Scale, biographical data, as well as the results of an assessment from the GMDS-ER. In this study the general performance of the ADHD sample on the GMDS-ER was found to be above average. Furthermore the performance of these children on the six Subscales of the GMDS-ER ranged from average to superior, with the poorest performance being on the Eye and Hand Co-ordination Subscale, and the best performance being on the Performance Subscale. Significant differences between the ADHD and normal sample were found on the General Quotient (GQ) as well as three of the six Subscales, namely, the Hearing and Speech, Eye and Hand Co-ordination and Performance Subscales. Generally, the results of the study suggest that a specific developmental profile for children with ADHD exists. Additionally, the study highlighted the success with which the GMDS-ER can be utilised on a specific clinical population.

- Description: The South African context necessitates developmental assessment measures with particular characteristics. A critical examination of a variety of potential measures indicates that there are very few measures available to meet these specific needs. The GMDS-ER is judged to be one such measure. This study explores the performance of South African children aged 4 to 7 years of age as it relates to that of British children (from the standardisation sample). The samples consisted of normal South African (n=129) and British (n=161) children, where normalcy refers to the absence of sensory, physical, or mental handicap. The study was done in an attempt to explore the suitability of using the GMDS-ER in the South African context. More specifically, the following two aims were pursued: 1. To explore and describe the general development of each of four year groups of a sample of British and South African children by utilising the general developmental quotient of the GMDS-ER 2. To explore and describe the comparative developmental profiles of each of the four year groups of a sample of British and South African children across the six developmental areas represented by the subscales of the GMDS-ER. Descriptive statistics and simple t-tests were used to accomplish Aim 1 and Hotellings T2 tests were mainly used in order to accomplish Aim 2. The major findings of the present study were as follows: 1. South African and British children’s overall performances (as measured by the GMDS-ER GQ) are similar. A great deal of variability exists between the GMDS-ER profiles of normal South African and British children (i.e., when individual subscales and year groups are considered). 3. In general, South African children performed better on the Locomotor and Personal-Social Subscales, while British children performed better on the Language and Practical Reasoning Subscales. Performance on the Eye and Hand Coordination Subscale was similar for the two samples and on the Performance Subscale performance was too variable to come to any general conclusions. In view of the findings, caution with regard to the use of the British-based norms in the South African context is recommended. Recommendations are made for the use of the GMDS-ER to help with the identification of specific classes of disorders in the South African context. Further investigation into the applicability of the GMDS-ER for South African use as well as the establishment of South African norms are final recommendations.

- Description: It is the objective of this treatise to highlight and demonstrate the role that can be played by Traditional Leadership Institutions in the development of their communities, demonstrate and advance the extent to which they can enhance their image and restore their dignity by embarking on community development projects that will improve the quality of life of their subjects in their jurisdictional areas. However, as the number of Traditional Leadership Institutions that can be investigated and researched was so large, it became necessary to focus attention primarily on the Rharhabe Kingdom with its seat and headquarters at Mngqesha Great Place in King William’s Town. The Mngqesha Great Place, the seat of the Rharhabe Kingdom is a typical example of a Traditional Leadership Institution selected from the six existing Eastern Cape Provincial Kingdoms. Attention is invited to the following fields which had to be explored since they serve the basis for the evolution of Traditional Leadership Institutions in South Africa. A historical background to Traditional Leadership and Governance in South Africa and the Eastern Cape provides some key issues of governance, management and administration, position, place and status of the institution during the pre- colonial and colonial periods, the period under apartheid rule, the independence period of the former homelands of Ciskei and Transkei territories with reflections on Tribal and Regional Authorities and Local Government Bureaux. A synoptic perspective of the effect of changes on the functioning of the Institution of Traditional Leadership is provided in some detail. This part is concluded with a brief history of the Rharhabe Kingdom. An overview of Traditional Leadership and Governance in the new South Africa since 1994 to date indicates the recognition and important role that Traditional Leadership Institutions can play. In this regard, there is policy and legislation that is in place on Traditional Leadership and Governance with a clear vision for implementation. Since 1994, there are many initiatives that have been undertaken by government in creating and maintaining an enabling environment for the efficient management and administration of the institution, transfer payments for different projects like funding the building of various Great Places and Provincial Policy Initiatives on Traditional Leadership and Governance. Institutional arrangements for Traditional Leadership Institutions reflect on the hierarchy of Traditional Leadership, for example, the position of the King as head of a Regional Authority (Ikomkhulu), the Chiefs under Kings as Heads of Traditional Authorities (Inqila) and Headmen as heads of the various Administrative Areas (locations). In order to give meaning to Government’s recognition of the Institution of Traditional Leadership, to enhance the institution and give it a role at the National, Provincial and Local levels, the government has established a National and Provincial Houses of Traditional Leaders with clear roles and responsibilities and provision for accountability of Traditional Leaders and structures. Regarding the role of Traditional Leadership Institutions in Governance and Development, it is clear that over many years, these institutions performed various governance functions. The policy framework on Traditional Leadership and Governance besides legislation specifies the duties and functions of these entities. With regard to the King Sandile Development Trust and its role in community development, the research reveals visionary leadership on the part of the Kingdom, with the Trust, since its establishment in 1999 being at the centre of all development initiatives at the Great Place besides government initiatives. The King Sandile Development Trust is therefore a legal entity established and funded in terms of law. It has its constitution, vision and clear objectives, procedural arrangements on administration, management and financial arrangements. The development role of the trust is reflected in the Queen’s Programme of Action and Implementation, headed by the Queen mother, Queen Noloyiso Sandile, the wife of His Majesty King Maxhobayakhawuleza Sandile. Besides, there are established tourism chalets providing not only revenue but also employment opportunities to many local subjects of the Kingdom. Finally, the treatise concludes with some general conclusion and recommendations and challenges that demand that traditional leaders be appropriately trained, its institutions adequately resourced, appropriately run and administered based on the need to account publicly on their performance.

- Description: It is the objective of this treatise to highlight and demonstrate the role that can be played by Traditional Leadership Institutions in the development of their communities, demonstrate and advance the extent to which they can enhance their image and restore their dignity by embarking on community development projects that will improve the quality of life of their subjects in their jurisdictional areas. However, as the number of Traditional Leadership Institutions that can be investigated and researched was so large, it became necessary to focus attention primarily on the Rharhabe Kingdom with its seat and headquarters at Mngqesha Great Place in King William’s Town. The Mngqesha Great Place, the seat of the Rharhabe Kingdom is a typical example of a Traditional Leadership Institution selected from the six existing Eastern Cape Provincial Kingdoms. Attention is invited to the following fields which had to be explored since they serve the basis for the evolution of Traditional Leadership Institutions in South Africa. A historical background to Traditional Leadership and Governance in South Africa and the Eastern Cape provides some key issues of governance, management and administration, position, place and status of the institution during the pre- colonial and colonial periods, the period under apartheid rule, the independence period of the former homelands of Ciskei and Transkei territories with reflections on Tribal and Regional Authorities and Local Government Bureaux. A synoptic perspective of the effect of changes on the functioning of the Institution of Traditional Leadership is provided in some detail. This part is concluded with a brief history of the Rharhabe Kingdom. An overview of Traditional Leadership and Governance in the new South Africa since 1994 to date indicates the recognition and important role that Traditional Leadership Institutions can play. In this regard, there is policy and legislation that is in place on Traditional Leadership and Governance with a clear vision for implementation.

- Description: As the divorce rate consistently rises, the occurrence of single parent families are becoming increasingly prevalent. Despite the marked increase in single custodial parents, research on this population (and more importantly, into the positive aspects such as their subjective well-being) has been neglected. Over the past three decades, psychologists have shifted the emphasis of their research from examining demographic and pathogenic factors to a positive psychology framework focusing on personality and resilience. The general aim of this study was to explore and describe the subjective wellbeing, including satisfaction with life and general happiness, of divorced, single custodial parents. In addition, this study aimed to identify potential patterns among the aspects of subjective well-being investigated and aimed to explore the relationships between these patterns. Thirty-five participants were included for participation in this study by means of non-probability, purposive sampling. The research measures included a biographical questionnaire, the Satisfaction with Life Scale (SWLS) and Affectometer-2 Scale (AFM-2). The data were analysed by the researcher and an independent statistician in terms of descriptive statistics and cluster analysis, or according to content analysis. This reflects a triangulation data collection and analysis method. Key findings included the following: The results of the SWLS indicated that the majority of participants reported being slightly dissatisfied with their lives. The results of the AFM-2 indicated that the participants generally had high levels of positive affect, and low levels of negative affect. However, the participants’ overall levels of happiness were still relatively low. A four cluster solution was obtained, with the clusters being significantly different from each other on all input variables. The first cluster experienced high levels of positive affect, low levels of negative affect, and high levels of overall happiness. The second cluster experienced predominantly slight dissatisfaction with their lives, high levels of positive affect, low levels of negative affect, and slightly low levels of overall happiness. The third cluster reported mostly dissatisfaction with their lives, low levels of positive affect, high levels of negative affect, and very low levels of overall happiness. The fourth cluster experienced predominantly slight satisfaction with xi life, slightly high levels of positive affect, neutral levels of negative affect, and low levels of overall happiness. It appeared that clusters containing participants who were satisfied with their jobs, were involved in a personal relationship and who participated in leisure activities, all experienced higher levels of subjective well-being. Overall, this study emphasises the value of and the need for South African research on the subjective wellbeing of divorced, single custodial parents.

- Description: At the outset of this treatise the development of the unfair labour practice is traced. The point is made that common law knows nothing about fairness and it is pointed out that the concept was introduced as a statutory concept in 1979. In 1995 the development of unfair labour practices since 1979 was relied upon to provide a list of unfair labour practices. The main thrust of the treatise concerns an evaluation of an unfair labour practice relating to benefits – listed presently in section 186(2) of the Labour Relations Act. Reference is made to Industrial Court cases and case law since 1996 is considered and commented upon. In particular, the issue of remuneration not being a benefit, and the fact that interest disputes are not justiciable as unfair labour practices for instance are canvassed.

- Description: Marketing strategy relies heavily on segmentation and positioning. Lifestyle and psychographics are increasingly being used as a basis for market segmentation. Marketers require deeper insight into the motivational factors that encourage purchases in order to tailor make offerings to suit individual needs. The focus is on customer relationship management in order to retain customers over a longer period of time, rather than once-off sales. This study examines how using the ancient and mystical technique of the Enneagram can improve customer relationship management and formulates a model for doing so. The Enneagram can be used as an effective base for psychographic segmentation by harnessing the diagnostic and predicative power therein. It is already being used in human resource development and strategic planning by companies and it seems fitting to apply it in yet another business area that can greatly benefit from this.

Virtuous living towards an African theology of wisdom in the context of the African renaissance

- Description: The structure of this study is a complex inter-relationship of a variety of sources in a theological work, namely, personal experience, African social and politico-economic context, philosophical reflection, wisdom traditions and Christian theology. These sources form a coherent inter-relationship which is foundational for an African theology of wisdom. The introduction gives an overview of my moral and theological formation. This is intended to provide a perspective through which the issue of moral orientation in African context has been approached. It is therefore entitled: Moral formation and the shaping of a theological mind. The first chapter answers the question: Why is Africa in need of a wisdom theology that addresses the issue of moral regeneration? This question is posed in the broader context of the current African Renaissance debates. The links between the Italian (European) and African Renaissance indicate that moral regeneration is a crucial part of the socio-political, intellectual and economic re-birth of Africa. This “socio-historical” source gives the context and urgency of a wisdom theology. It is therefore entitled: A contextual analysis: The European and African Renaissance. The second chapter re-asserts the rise of virtue ethics as an alternative ethical theory to the predominant deontological and utilitarian traditions. This is achieved through analysing Alisdair MacIntyre’s earlier work, After Virtue: A Study in Moral Theory (1981), set in the context of Iris Murdoch and Elizabeth Anscombe, the modern initiators of a virtue ethic. This “philosophical” source gives the theoretical framework that addresses the question of moral formation. It is therefore entitled: A philosophical analysis: The rise of virtue ethics as alternative ethical theory. The third chapter is devoted to two related “wisdom” themes: Firstly, the seven traditional virtues are briefly described highlighting the virtue of wisdom as foundational. Secondly, the idea of wisdom is further developed via three wisdom traditions, namely: wisdom in the Hellenistic, Judeo-Christian and African traditions. This “sapiential” source gives this African theology of wisdom its most important building blocks. This chapter is therefore entitled: A sapiential analysis: Wisdom as foundation for virtue ethics in Africa. The last chapter brings the previous sources together under a specific theological perspective. It draws on aspects of recent African theologians’ work, notably: Kwame Gyekye and Benezet Bujo who engage with and bring together Western and African theological traditions. I answer a pertinent question, “What does such a ‘theological’ perspective entail?” I draw on Scripture and its Trinitarian tradition to demonstrate how African wisdom, reinforced by the framework of virtue theory, and developed in the context of present-day Africa by an African student of theology, has the potential to contribute to the moral transformation of Africa. This more overt “theological” source is the distinctive Christian enterprise of an African wisdom theology. The chapter title is aligned with the overall title of this study: A theological analysis: Toward an African virtue ethics? To this end, this study achieves its attempt to construct an inter-related framework from which an African theology of wisdom may emerge.

- Description: Web Usage Mining (WUM) can be used to determine whether the information architecture of a web site is structured correctly. Existing WUM tools however, do not indicate which web usage mining algorithms are used or provide effective graphical visualisations of the results obtained. WUM techniques can be used to determine typical navigation patterns of the users of organisational web sites. An organisational web site can be described as a site which has a high level of content. The Computer Science & Information Systems (CS&IS) web site at the Nelson Mandela Metropolitan University (NMMU) is an example of such a web site. The process of combining WUM and information visualisation techniques in order to discover useful information about web usage patterns is called visual web mining. The goal of this research is to discuss the development of a WUM model and a prototype, called WebPatterns, which allows the user to effectively visualise web usage patterns of an organisational web site. This will facilitate determining whether the information architecture of the CS&IS web site is structured correctly. The WUM algorithms used in WebPatterns are association rule mining and sequence analysis. The purpose of association rule mining is to discover relationships between different web pages within a web site. Sequence analysis is used to determine the longest time ordered paths that satisfy a user specified minimum frequency. A radial tree layout is used in WebPatterns to visualise the static structure of the organisational web site. The structure of the web site is laid out radially, with the home page in the middle and other pages positioned in circles at various levels around it. Colour and other visual cues are used to show the results of the WUM algorithms. User testing was used to determine the effectiveness and usefulness of WebPatterns for visualising web usage patterns. The results of the user testing clearly show that the participants were highly satisfied with the visual design and information provided by WebPatterns. All the participants also indicated that they would like to use WebPatterns in the future. Analysis of the web usage patterns presented by WebPatterns was used to determine that the information architecture of the CS&IS web site can be restructured to better facilitate information retrieval. Changes to the CS&IS web site web were suggested, included placing embedded hyperlinks on the home page to the frequently accessed sections of the web site.
