- Description: Herein, we propose novel quinolones incorporating an INH moiety as potential drug templates against TB. The quinolone-based compounds bearing an INH moiety attached via a hydrazide–hydrazone bond were synthesised and evaluated against Mycobacterium tuberculosis H37Rv (MTB). The compounds were also evaluated for cytotoxicity against HeLa cell lines. These compounds showed significant activity (MIC90) against MTB in the range of 0.2–8 μM without any cytotoxic effects. Compounds 10 (MIC90; 0.9 μM), 11 (MIC90; 0.2 μM), 12 (MIC90; 0.8 μM) and compound 15 (MIC90; 0.8 μM), the most active compounds in this series, demonstrate activities on par with INH and superior to those reported for the fluoroquinolones. The SAR analysis suggests that the nature of substituents at positions −1 and −3 of the quinolone nucleus influences anti-MTB activity. Aqueous solubility evaluation and in vitro metabolic stability of compound 12 highlights favourable drug-like properties for this compound class.

- Description: This is an account of the emancipatory struggle that faces agents who seek to change the oppressive social structures associated with neo-liberalism. We begin by ‘digging amongst the bones’ of the calls for resistance that have been declared dead or assimilated/co-opted by neoliberal theorists. This leads us to unearth, then utilize, Paulo Freire’s Pedagogy of the Oppressed, Steve Biko’s Black Consciousness and Shiv Visvanathan's ideas; which are examples of Roy Bhaskar’s transformative dialectic. We argue, using examples, that cognitive justice – a concept common to each of our chosen theorists – is vital in enabling emancipatory social learning. By embracing cognitive justice, the agents gained confidence, which led to their increased ability to champion community and non-academic knowledge. It also uncovered structural tensions – attendant in neoliberalism – around privilege. By articulating these tensions, the participants were able to ‘come closer together’. Such processes, initiated by ensuring cognitive justice, are possible steps in achieving universal solidarity; which is likely to be a necessary step along the path of achieving emancipation.

- Description: The South African railway industry has seven times more of labour productivity than its counterparts within Sub-Saharan Africa. Though, when compared to countries in Europe, the United States of America, and China, the South African railway industry is non-competitive. The National Railway Safety Regulator of South Africa (NRSR) has been gradually considering novel ways of measuring organisational performance which encompass a broad approach that goes beyond infrastructure. To that end, a business excellence model adoption is proposed for an integrated agile performance management system. Performance management is viewed as a method that involves measuring goals against a set of standards within an organisation so as to evaluate whether or not the intended objectives have been (successfully) accomplished. Management quality systems (MQS) is one seamless system which integrates the Individual Performance Assessments, ISO-Systems, and Total Quality Management (TQM) in order to achieve the operational distinction in pursuit of the organisational performance excellence. Similarly, organisational excellence is continuous efforts made to build an internal framework of standards and processes intended to involve and motivate employees to deliver products and services within organisational expectations. Various business excellence models, such as the European Framework of Quality Management (EFQM), Common Assessment Framework (CAF), Malcolm Bridge National Quality Awards (MBNQA), International Standard Organisation (ISO) 9000/1/4 and South African Excellence Models (SAEM) have been proposed as continuous improvement (CI) tools. Embedded within these frameworks are areas such as leadership, strategic planning, total quality human resources management, CI, communications, culture, process management and organisational results. Even though attention has been paid to quality performance management in literature, limited empirical research has been conducted on the impact of these models to organisational performance in the railway industry. Moreover, few studies have been conducted to investigate this within the South African context. In this study, the difference in perceptions regarding the envisioned model will be measured to determine the level of employee awareness on quality management. Secondly, the impact of the implementation of MQS factors on organisational performance is investigated to determine critical success factors. Lastly, the barriers to effective MQS implementation are explored and discussed. The study focuses on enablers (i.e. leadership, strategy planning, total quality human resources management, CI, communications, culture and process management) and their impact on organisational performance. An empirical survey has been conducted in this study to examine the influence of the identified factors on business performance. In order to measure the impact of the above factors on improving of organisational performance, the MQS model has been used. The data collected has been statistically analysed using descriptive statistics, correlational relationships and regression analysis. The results of the study indicate that the MQS is useful and effective for the improvement of organisational performance in pursuit of organisational excellence. Furthermore, the critical success factors that, when prioritised, will directly influence organisational performance have been identified. Also, all the measured factors are correlated with organisational performance. It has been proven that though there are signs of implementation of MQS, the employees have not yet owned the process and do not implement quality practises in their daily operations. It is recommended that for future studies a more representative sample be sought in order to validate the relationship between strategy planning; communication and organisational performance, and the overall impact of implementing of MQS in the rail industry.

- Description: The purpose of this Qualitative research was to determine the metrics required to define the Long-Term Sustainability of a Multinational Enterprise (MNE). The study investigated and analysed how the individual subsidiaries of a listed organisation interpreted LTS and what measurements (metrics) were the most important in supporting this long-term approach. The research analysed questionnaires administered to managers from different disciplines within the organisation. This process sought to accumulate a set of responses and through the statistical analysis of these responses, in particular, extensive qualitative research was used to find a common thread of relevant metrics, which can be used presently and in the future to determine LTS. The researcher reviewed models and the literature to establish a set of questions for the construction of individual questionnaires. This was based on current theory combined with institutional knowledge and experience. The questionnaires were designed to provoke responses from management of their view of the important contributors to LTS. The individual questionnaires (Annexures I to VIII) comprised a series of focused questions and multiple-choice answers based on either 5 or 10-point Likert scales and a few open-ended questions. The main respondents were VPs, MDs, OMs, Human Resource Managers, Financial Managers, and Sales and Marketing Managers of the subsidiaries within the MNE. These “At the heart of an excellent manufacturing business rests the efficiency of its operations, the commitment of the people who manufacture the products, the level of motivation of the workforce, the passion of its salesforce and the innovation shown by its engineers” respondents were all best suited to answer questions at the required level of expertise, when taking into consideration the LTS of the organisation. The data obtained from the research was used to devise suggested scorecards that may be used as guidelines for current and future initiatives when considering LTS. Qualitative research methods were used in this research as they seek understanding of “how things work in particular contexts”. This allows for the building of new theory and the conceptual advancements of knowledge, starting with very general concepts which, as the research progresses, change their definition (Brannen, 2016). In qualitative research, researchers use themselves as the instrument, attending to their own cultural assumptions as well as to the data. to achieve imaginative insights into the respondents’ social worlds. (McCracken, 1988). Concepts and categories are relevant to qualitative research. as quantitative research is an exercise in analytical induction.

- Description: A comprehensive academic support at the public nursing college is important. Despite this, there is no such support in public nursing colleges in the Eastern Cape Province of South Africa. The aim of the study was to develop an academic support programme for students in order to improve their success in Higher Education. The study endeavoured to answer the following questions: What are the academic support needs of students at the public nursing college in the Eastern Cape of South Africa? What conceptual framework can be developed for the academic support programme of students? What academic support programme can be developed for students at the public nursing college? What guidelines can be developed for implementation of academic support programme of students? The objectives were: to describe academic support needs of students at the public nursing college in the eastern Cape Province of South Africa; to develop a conceptual framework for the academic support programme for students at the public nursing college in the Eastern Cape of South Africa; to develop an academic support programme for students at the public nursing college in the Eastern Cape in south Africa and lastly to describe guidelines for implementation and evaluation of the academic support programme. The research design used in this study was quantitative, qualitative, descriptive, evaluative, and theory generation. The study was conducted according to four phases. Phase one focussed on academic supports needs of the student. Phase two focussed on development of conceptual framework for the students at the public nursing college in Eastern Cape Province. Phase three focussed on the development of the academic support programme for the students, whereas phase four focussed on description of guidelines for implementation and evaluation of the academic support programme. The population of the study consisted of students undergoing training in a four-year programme at the Public Nursing College. The target population was the students in the same programme from level one to level four of training. The sampling technique used was a probability sampling with multi-stage and cluster sampling techniques being utilized. The total sample was n=333 participants. A quantitative self-developed questionnaire was used to collect empirical data. The questionnaire consisted of eight sections. Descriptive data was analysed using Statistic Package of Social Sciences (SPSS) version 24. Exploratory factor analysis was conducted on the descriptive data collected in phase one. Concept analysis and identification were done through the utilisation of exploratory factor analysis. The conceptual framework for the academic support programme was identified through the analysed factors. Fifteen factors were derived from the descriptive data. The conceptual framework of the academic support programme discussed in Chapter 5 was used also in the development of the academic support programme. It is in this chapter that assumptions, context, stakeholders, process, outcome, dynamics and, lastly, the recipient were discussed, along with a description of the programme. The programme was evaluated in accordance with the criteria for programme evaluation. The recommendations brought forward for the academic support programme were: The guidelines have to be tested for the implementation of the programme; benchmarking should be done to compare with other institutions of higher learning regarding their academic support programmes; an academic brochure regarding academic support must be available in the college and should be given to students on arrival as part of a package; and neutral researcher should conduct the same research in the same college.

- Description: Public service broadcasting in South Africa is the responsibility of the South African Broadcasting Corporation (SABC), which is the only national public service broadcaster mandated through the South African Broadcasting Act. Consequently, the SABC is meant to be a tool for information, entertainment and education that is accessible by all citizens, regardless of their social and economic status in the community. However, like all enterprises, the SABC requires a sustainable source of revenue to function effectively. It is of the utmost importance that the SABC has the necessary resources and stable source of revenue to fulfil its public service responsibilities, as a lack of proper resources and insufficient funds can hinder the provision of these services. The global economic crisis has put all public and private sector companies under financial pressure. The effect of this financial pressure was felt by the SABC and led to financial loss, subsequently posing a serious threat to the financial sustainability of the SABC. Given this situation, this study sought to develop a sustainable funding framework by identifying factors that influence the financial sustainability of the public broadcaster in South Africa and to provide alternative strategies for improving the financial sustainability of the public broadcaster in South Africa, which has thus far proved unsustainable and insecure. Past research has focused mainly on defining a public service broadcaster or a public mandate, or considered the future of public service broadcasters. In these past studies, researchers mostly debated the SABC funding challenges without attempting to develop a funding framework for the SABC. To achieve the objectives of this study a quantitative approach using a web-based distribution survey method was adopted to test the hypotheses. The participants were randomly selected in each provincial SABC office from the database of managers, unionised and non-unionised employees, as well as the database list of freelancers. A total of 432 participants, selected through a stratification sampling technique, were considered and 175 respondents completed the survey. However, after data clean-up only 168 respondents’ data was usable. Based on the analysis of various secondary sources, a theoretical framework regarding sustainable funding of the public broadcaster in South Africa was constructed. The proposed theoretical framework indicated that the intervening variable, which is sustainable funding, is possibly influenced by three independent variables namely, internal stakeholders, a competitive environment and the management of resources. The perceived outcomes (dependent variables) of a sustainably funded public broadcaster were identified as customer benefits and organisational performance. The computer programme STATISTICA was used for data analysis. Descriptive statistics was used to summarise the data of the respondents and allow easy interpretation by the researcher. Inferential statistical analysis was used to test for relationships between identified variables using a validity test, reliability test and correlation and regression analysis. The empirical results revealed that sustainable funding formed two separate intervening variables. These variables were renamed sustainable funding enabler and sustainable funding as part of management control. The dependent variable customer benefits and organisational performance also loaded onto a single factor and was renamed organisational outcomes. Given the results, it was determined that internal stakeholders, competitive environment and management of resources have a significant positive influence on the sustainable funding enabler for the public broadcaster. In turn, sustainable funding enabler had a significant positive influence on the organisational outcomes (customer benefits and performance). On the other hand, only the management of resources had a positive influence on sustainable funding as part of management control of the public broadcaster. Furthermore, sustainable funding as part of management control still had a significant positive influence on the organisational outcomes. The majority of the respondents agreed in their responses in relation to the variable items measuring sustainable funding as a part of management control and its influence to the organisational outcomes of the public broadcaster. In conclusion, sustainable funding of the public broadcaster is influenced by the identified variables, namely internal stakeholders, competitive environment and management of resources. In turn, sustainable funding has a positive influence on the organisational outcomes (customer benefits and performance). It is envisaged that the empirical evidence provided in this study will assist the SABC in understanding the factors influencing financial sustainability and thereby assist the organisation during strategy development and decision making. This study provides relevant and practical recommendations that will make the SABC financially sustainable. Finally, the objectives of this study were achieved and the research questions were answered. This study can also act as a foundation for other studies, thereby contributing to the body of knowledge.

It is envisaged that the empirical evidence provided in this study will assist the SABC in understanding the factors influencing financial sustainability and thereby assist the organisation during strategy development and decision making. This study provides relevant and practical recommendations that will make the SABC financially sustainable. Finally, the objectives of this study were achieved and the research questions were answered. This study can also act as a foundation for other studies, thereby contributing to the body of knowledge.

- Description: Psychobiographical researchers methodically formulate life histories and interpret them by means of psychological theories. The research typically focuses on exemplary and completed lives. The cases that are studied are usually of individuals who are of particular interest to society as a result of excelling in their particular fields, be they to benefit or detriment of society. Temple Grandin was chosen for this study using purposive sampling as she meets the psychobiographical requirement of being an extraordinary individual. As an individual with autism Grandin faced many challenges growing up. Despite a difficult and absent beginning, Grandin developed into a stable and scientifically creative adult who contributes to society. She excels as an animal scientist and designer of humane livestock handling facilities and has an international reputation for her contribution to the livestock industry and animal welfare. The primary aim of this study is to describe and interpret the life of Temple Grandin through Erikson’s (1950/1973) theory of psychosocial development. A mixed method approach (Yin, 2006) was employed for the conduction of this study. The overarching data processing and analysis guidelines for this study were provided by Miles and Huberman (1994, 2002a, 2002b). The conduction of the processing and analysis of data was aided by Alexander’s (1988, 1990) method of asking the data questions as well as an integration of Yin’s (2014) time series analysis with Erikson’s (1950/1973) triple bookkeeping approach. This study contributes to the development of psychobiographical research in South Africa as well as to personality and developmental theory.

- Description: This research presents a case study report of interview encounters with two novice white South African clinical psychologists. A psychosocial research methodology is employed to examine the discursive strategies that participants engage in when speaking about whiteness in the context of their professional identity and practice, as well as to examine the ways in which these discursive strategies support or constrain ‘mentalizing’ in relation to raced experience. One case study highlights an individualistic discourse of ‘racial innocence’, which constructs the speaker as being free of racial enculturation and consciousness, eliding a broader social context. I argue that this discourse closes down mentalizing in relation to more difficult, intractable aspects of raced experience in clinical work, relating to differences in positionality as well as issues of inequality. I also propose that this discourse may be understood in terms of a ‘pretend’ mode of thought, where aspects of the wider social context and of race in particular are experienced as being unrelated to intimate personal experience. The other case study highlights a discourse of ‘uneasy whiteness’ that involves awareness of white positionality, and that is grounded in a constructionist sensibility. This positions the speaker as being inevitably implicated in white privilege and racism in ways that she may be ignorant of. I argue that the discourse facilitates a particular type of mentalizing that is sensitive to the interpellation of intimate personal experience with a wider social context that encompasses a range of discourses and practices. It closes down mentalizing, however, in so far as it allows a reified construction of whiteness. I find the concept of psychic equivalence, which equates external (concrete, factual) reality and internal (subjective, symbolic) reality, useful in terms of understanding this reification. Overall the research highlights the tension between constructionist and individualistic modes of thinking within clinical psychology research and practice in the South African context. At the level of methodology, it presents an example of how these modes may be integrated within research. At the level of content, it explores differences between constructionist and individualistic talk in relation to race and psychological practice.

- Description: The importance of education cannot be overemphasized. Education has been identified as the most critical instrument for empowering individuals with the necessary knowledge and skills, which can give them access to productive employment. Also, the future of a country is based on the quality of education acquired by its citizens which helps in transforming it from pre-literate to contemporary nationhood. Many international treaties and initiatives in the world have made special provisions for education as a duty of every government which must be given to every citizen as of right, irrespective of gender or social class. Amongst these international initiatives is the Education for All (EFA) Goals, a time-bound global movement towards the provision of education for every one led by the United Nations Educational, Scientific and Cultural Organization (UNESCO). There are six goals in all. This study investigated one of the EFA goals, the goal 5. The aim of the study was a qualitative assessment of the achievement of gender equality goal under the Education for All (EFA) goals, a study of Lagos State, Nigeria. The theoretical framework of the study is informed by the Social Justice Theory and the Social Justice Praxis Theory. Scholarly works and literatures on girl-child education, gender and education, and gender balancing in education were reviewed. The study followed qualitative research approach which utilizes an interpretive research paradigm that provides a collective voice from the participants. The research area was purposively selected as Lagos State being a former capital of Nigeria and still the commercial nerve centre of the nation. Although it is the smallest state in Nigeria in term of size, it remains the most populous in the country with a projected population of 20,546,999 (13.5percent Nigeria’s total population). A sample of 16 participants were purposively selected because they were the officers directly in charge of the implementation government policies on education in the State. The data was collected through in-depth recorded interview sessions and secondary data were sourced through official documents downloaded online and from Lagos State Ministry of Education. Based on the thematic analysis of the data collected, the study found out that the State government had established policies and measures to provide qualitative education for all the citizens on a non-discriminatory basis. Thus, the goal of gender parity in terms of enrollment of boys and girls has been relatively achieved in the state. However, there were still some challenges of equality in the learning process and outcome. The study therefore recommends that schools should be made attractive and conducive as possible to assist the educational attainment of any student. This could be achieved by promoting positive values and attitudes towards education, all the stakeholders in the education sector must be involved in the business of running the school. There should also be a form of resourcing and expansion of the school facilities through the Public - Private Partnership in education.

- Description: Approximately twelve million children under the age of 18 years worldwide have lost one or both parents due to HIV/AIDS. Several factors can be considered to contribute to the psychosocial well-being of HIV/AIDS orphaned teenage girls, among others, poverty, lack of social support, post-traumatic stress disorder, stigma and discrimination which have adverse consequences to the said teenager. Evidence suggests that HIV/AIDS orphaned adolescent girls may engage in relationships with older men to fund for school and other expenses and also to fulfil the need for a parental figure or emotional support, affection and attention. Against this background, this research study intended to investigate the psychosocial wellbeing of adolescent females orphaned by HIV/AIDS in the Nkonkobe Municipality. Fourteen Xhosa- speaking adolescent females between the ages of 15 and 18 years were recruited by means of snowball technique to participate in a qualitative study. Semi-structured interviews allowed sensitive issues to be discussed more easily. To ensure confidentiality and anonymity, the researcher suggested pseudonyms for the participants. This took place after the management of Isibindi Community Centre from Alice and Child Welfare from Fort Beaufort, both from the Eastern Cape, South Africa granted permission to conduct the study. The social worker from child welfare and the principal of Lingeni High School, assisted in ensuring that the participants from the two data collection sites, are organized prior the study. The researcher used Guba’s model whereby Guba and Lincoln’s model to ascertain the trustworthiness of qualitative research by following these principles; credibility, dependability, transferability and confirmability. The framework analysis which uses a thematic approach was utilized to analyse data. Meanings were formulated and they produced clusters of themes. The findings of the study revealed that HIV/AIDS orphaned adolescent females experienced grief of the loss of parents which made it difficult by deepening poverty and multifaceted challenges. Participants’ psychological well-being was impaired, subsequently they engaged in risky sexual behaviour, that is, substance abuse and multiple sexual partnership. However, an element of hardiness emanated from the participants’ personalities. They demonstrated problem-focused coping with the challenges they confront, despite the lack of consistent support structures. Their resiliency and sense of belonging owing to the nature of support from extended families ignited a sense of purpose amongst the participants. In conclusion, it is recommended that children orphaned by HIV/AIDS should be told of the cause of the death of their parents as this will make them aware of the dangers and consequences of their actions.

- Description: The Langer Heinrich calcrete hosted uranium deposit is situated approximately 90 km to east of the coastal town of Swakopmund in Namibia. It is run by an Australian owned company, Paladin Energy Limited, along with China National Nuclear Corporation (CNNC) who maintain 25% of the shares. Production commenced in 2007 and has been ongoing. Carnotite is the primary and only ore mineral, and the nature of mineralisation within the Langer Heinrich palaeo channel dictates westward-directed continuous open pit mining. Smaller-scale 1micro pits target near-surface, high-grade, lenses toward the east. The high variability in uranium grade over relatively short distances complicates the grade estimation process. This combined with a low uranium price, and a study aimed at optimising of mine production is one of the key drivers for the research presented in this thesis. The efficacy of four resource estimation techniques, commonly used in the mining industry, are investigated by application to variable exploration, infill drilling and grade-control drill pattern spacing. The drill spacing includes regular grids of 50 m x 50 m, 25 m x 25 m and 12,5 m x 12,5 m exploration data. Also included is grade control drill data, drilled on a 4 m x 4 m spacing. The current selective mining unit (SMU) is 4mE x 4mN x 3mRl which is an indication of the minimum dimension whereby the loading equipment can separate ore from waste. The two datasets are processed by four estimation techniques: Inverse Distance Weighting (IDW, squared and cubed), Ordinary Kriging (OK), Multiple Indicator Kriging (MIK) and Conditional Simulation (CS). The two datasets consisted of real-time mining data from pit G1 (micro-pit) in the eastern parts of the mining licence, and pit H1 (continuous larger open pit) in the western area of the palaeo channel. The reconciliation project aims to provide results suitable for devising optimised mining strategies, particularly in future targets where drill spacing can perhaps be improved to provide suitable data with a greater cost saving strategy. Along with the optimal drill spacing or combination thereof, a preferred estimation technique can be suggested and recommended for future operations that involve mining of surficial calcrete-hosted uranium deposits. Results of this study show that 12,5 m x 12,5 m drill spacing provided estimation accuracies similar to that of the narrow 4 m x 4 m grade control spacing (blast hole drilling spacing). The 12,5 m x 12,5m spacing has potential for accurate grade estimations during mining, and could be supplemented by infill downhole radiometric logging on a 4 m x 4 m spacing when 1 Micro pit: Small pits within palaeo channel usually targeted for their near surface high-grade ore necessary. In general, Multiple Indicator Kriging (MIK) provided the most accurate and robust estimations on the wider spaced exploration data and conditional simulation (CS) proved more efficient on the narrow grade control data. These results correspond with current exploration practices for surficial uranium deposits world-wide. Deposit type, therefore complexity and hence SMU sizes play a pivotal role in drill hole planning and estimation accuracies.

- Description: This study was centred on the Agricultural Innovation System in the North West Province, South Africa as a response to climate change. The study developed during a time when Climate-Smart Agriculture emerged in policy and was developed as a strategic agricultural innovation process in response to changes in climate that increased food insecurity. The Agricultural Colleges embedded in the agricultural system realised that they were teaching students without a clear provision for climate change and therefore needed to initiate climate responsive innovations to comply with the Climate-Smart strategy that had been proposed by the provincial authorities. This provided the context for the study to track and support the innovation process of transitioning towards Climate-Smart responsive curriculum and learning practices within the system. A theoretical framework for the study was developed using a Cultural Historical Activity Theory perspective. This allowed the researcher to approach the research process as two case studies of innovation within the Agricultural Innovation System of the North West Province. The study developed as an iterative process of innovation support and tracking. At the early stages of the research process, data were generated through document analysis and a survey completed by the research participants at the preliminary consultative workshop. The contextual data allowed the researcher to begin to develop a clear contextual profile for both case studies. The consultative workshops were held to orientate the research around the central problems and challenges related to curriculum alignment with provincial Climate-Smart Agricultural policies. The methodology thereafter was developed as an iterative process of successive intervention-innovation workshops where the participating staff in each college reviewed their curriculum with the support of a Climate-Smart Innovation Tool. This tool was developed as a mediating resource for participants to undertake intervention work towards curriculum innovation in their context. The historical analysis from the two consultative workshops and the data derived from the initial use of the Climate-Smart Innovation Tool was used to model the activity systems in the respective colleges and the provincial system. This analysis enabled the researcher to scope how the system was currently functioning and how it had changed over time. During the workshops, curriculum innovations were reviewed and a fuller picture of the challenges of system innovation emerged, especially from a curriculum innovation vantage point. This system analysis was used to analyse emergent tensions and contradictions within the system and to build a picture of the complexities of participating staff initiating innovations towards Climate-Smart responsiveness in the colleges and within the Agricultural Innovation System. During the review and tracking of the supported innovation process the Climate-Smart Innovation Tool was developed into online sub-tools where either Departments or individual lecturers could review and track their own Climate-Smart responsiveness. The tool was shown to be a useful tool for surfacing contradictions, and identifying absences, and thus for charting out the start of reflexive learning and change processes needed for introducing climate responsive knowledge into the system. The study reveals that catalysing of curriculum and learning system innovation aligned with wider innovations in the agricultural innovation system requires specific tools, time and the understanding of the importance of micro-level innovation. The innovations within the system revealed the significance of allowing for time and processes that facilitate ‘ascending’ from the abstract concept of Climate-Smart Agriculture into more concrete curriculum processes. The curriculum review tool developed for this study served as an important double stimulation tool, along with activity system mapping, and ongoing refinement and clarification of the object of Climate-Smart Agriculture and associated contradictions and action plans for climate smart responsiveness in the college context. The tools and processes that were developed during this study, assisting in the emergence of micro-level innovation of the curriculum and learning system. The barriers and processes hampering curriculum and learning innovation within the system were identified. The study concludes with the recommendations on how a Climate-Smart innovation process might best be supported with reflexive tools within a curriculum and learning system during a time of institutional flux.

The methodology thereafter was developed as an iterative process of successive intervention-innovation workshops where the participating staff in each college reviewed their curriculum with the support of a Climate-Smart Innovation Tool. This tool was developed as a mediating resource for participants to undertake intervention work towards curriculum innovation in their context. The historical analysis from the two consultative workshops and the data derived from the initial use of the Climate-Smart Innovation Tool was used to model the activity systems in the respective colleges and the provincial system. This analysis enabled the researcher to scope how the system was currently functioning and how it had changed over time. During the workshops, curriculum innovations were reviewed and a fuller picture of the challenges of system innovation emerged, especially from a curriculum innovation vantage point. This system analysis was used to analyse emergent tensions and contradictions within the system and to build a picture of the complexities of participating staff initiating innovations towards Climate-Smart responsiveness in the colleges and within the Agricultural Innovation System. During the review and tracking of the supported innovation process the Climate-Smart Innovation Tool was developed into online sub-tools where either Departments or individual lecturers could review and track their own Climate-Smart responsiveness. The tool was shown to be a useful tool for surfacing contradictions, and identifying absences, and thus for charting out the start of reflexive learning and change processes needed for introducing climate responsive knowledge into the system. The study reveals that catalysing of curriculum and learning system innovation aligned with wider innovations in the agricultural innovation system requires specific tools, time and the understanding of the importance of micro-level innovation. The innovations within the system revealed the significance of allowing for time and processes that facilitate ‘ascending’ from the abstract concept of Climate-Smart Agriculture into more concrete curriculum processes. The curriculum review tool developed for this study served as an important double stimulation tool, along with activity system mapping, and ongoing refinement and clarification of the object of Climate-Smart Agriculture and associated contradictions and action plans for climate smart responsiveness in the college context. The tools and processes that were developed during this study, assisting in the emergence of micro-level innovation of the curriculum and learning system. The barriers and processes hampering curriculum and learning innovation within the system were identified. The study concludes with the recommendations on how a Climate-Smart innovation process might best be supported with reflexive tools within a curriculum and learning system during a time of institutional flux.

- Description: For more than a century fingerprint evidence has been used as a tool for the forensic identification of offenders, and has generally been accepted without being tested, challenged or scrutinized because the courts were convinced that no prints look alike or are the same. Fingerprint evidence has been used and accepted on the basis that each person’s friction ridges are unique, that the ridges are permanent and can be transferred to a surface. However, the transferability of the uniqueness raises issues that are very significant in relation to the reliability of fingerprint evidence because only a partial impression is typically transferred. Furthermore, the print can be distorted as a result of pressure and this inevitably affects the impression. Nevertheless, in recent and authoritative Reports from the United States and Scotland, criticisms are being raised against fingerprint evidence. These challenges include the fact that to date there has not been a study to validate the reliability of fingerprint individualisation, the fact that there is no specific requirement with regard as to how much constant or uniform detail between latent print and known print suffices to reach a decision of identification and the fact that there are no objective standards coupled with the problem that there is a lack of scientific validity of the method used for comparisons. This study reviews the law relating to fingerprint evidence in the light of the reports produced by the Office of the Inspector General, United States Department of Justice, Reviewing the Mayfield Case (US) in 2006, the National Academy of Sciences (US) Report in 2009, the Fingerprint Inquiry Report by Lord Campbell in Scotland in 2011, the National Institute of Standards and Technology and National Institute of Justice (US) Report in 2012, and the President’s Council of Advisors on Science and Technology Report (US) in 2016, so as to establish lessons for South African lawyers in as far as reliability, weight and admissibility of fingerprint evidence is concerned. Finally, this study concludes that South Africa’s norm of accepting fingerprint evidence as unquestionable is problematic in law and in science and that there is a need for reform regarding the manner in which fingerprint evidence is evaluated by the courts.

- Description: This study examines how the implementation of CAPS Life Skills curriculum training (as a recontextualising process) is engaging teachers in environmental education. The research was centred on training manuals for Life Skills (Official Recontextualisation Field) and their use in CAPS training at district level in two Eastern Cape sites of recontextualisation (Professional Recontextualisation Field). During the training, teachers developed lesson plans that were reviewed and group interviews were conducted on the training process and its outcomes. The manuals, training process, lesson plans and interview transcripts were analysed for evidence of environmental education, notably content, teaching and learning methods and assessment strategies. Bernstein’s (1990) framework of the pedagogic device underpins this study. Here the concept of the relay is key for tracking the "relay” of the content, teaching and learning methods and assessment strategies through the processes of recontextualisation into the lesson plans for the field of production. During the process of de-location and relocation, gaps are created and this study sought to track and probe patterns of omissions that took place during the relay process in two cases of training. The review of the in-service training course process of recontextualisation and its cascading approach exposed challenges of omission as it became clear that at each level of the recontextualisation process, gaps were apparent. The study highlighted how the 3-5 day workshop process reviewed was not a robust model for professional development. It was not effective and changes in the mode of delivery and processes of support that reach into curriculum practice in the context of the school are recommended. The study concludes that there is a need for continuous professional development as teachers need ongoing support especially for a "new” curriculum like CAPS that is content driven.

- Description: The research used a change management approach to analyze the restructuring of the Nelson Mandela Academic Hospital from a tertiary to a central hospital. The study was underpinned by two objectives. Firstly, to analyze the restructuring of the Nelson Mandela Academic Hospital from a tertiary to a "central" hospital using the Core Elements Framework of change management developed by Antwi and Kale (2014). Secondly, to use the knowledge gained through literature review combined with the experiences of the managers at Nelson Mandela Academic Hospital to inform future healthcare reforms in general and particularly in the restructuring of hospitals. The Core Elements Framework by Antwi and Kale (2014) identifies six fundamental change elements from both emergent and planned change management approaches. The six elements are regarded by theorists from the two different schools of thought i.e. emergent change and planned change as key for successful change. The Core Elements Framework by Antwi and Kale, (2014) demonstrates the strength of not viewing the two approaches to change management as mutually exclusive but as complementing each other when the other is falling short. The study identified the following: ■ The change was prompted by clearly identifiable external factors more than internal factors. ■ There was notable lack of organizational harmony which may have negatively impacted the change process. ■ The Private Public Partnership (PPP) funding model which was aimed at delivering the central hospital collapsed, after a study discovered that it benefited the private sector more than the public sector. ■ There was no proper consultation of major stakeholders for preparation of the change. ■ Resources in all material forms were not made available for the change to take off, this means that there was no organizational capacity to execute the change. The study draws the conclusion that lack of organizational capacity, organizational harmony and a proper consultation process for stakeholders are the main reasons why the restructuring of the Nelson Mandela Academic Hospital is not yielding the desired results. The study recommends that organizations should implement a multidimensional approach for any change initiative to be successful and that organizations must ensure the availability of the necessary resources when embarking on change.

- Description: The Pharmaceutical Industry is facing substantial challenges due to the continuous evolving world of technologies, global competitiveness, price regulation, environmental and safety requirements. In this environment asset maintenance evolved and became increasingly important in business over the last couple of decades. Traditionally industry favoured a reactive maintenance strategy but over the years changed to proactive maintenance strategy due to the advancement of technology and skills of maintenance personnel. With increasing automation and mechanisation, production processes are becoming highly complex and the cost associated with asset maintenance has increased consistently over the decades. Studies have shown that about 15-70% of production costs can be attributed to asset maintenance and one-third of maintenance costs are wasted due to inefficiencies in planning. Furthermore, the selection of an effective maintenance strategy is a challenge due to maintenance output that is difficult to measure and quantify. This treatise will investigate the application of a risk based strategy on asset maintenance planning and spare part management of a pharmaceutical company and compare it to best practices. The theory of risk analysis was reviewed and risk analysis pertaining to maintenance planning and spare part management in the Pharmaceutical industry explored. Questionnaires were sent to selected engineering and relevant departments in order to analyse the challenges and good practices in the company relating to spare part management and maintenance planning. A risk based model for the pharmaceutical company was developed after the information gathered in the research. The recommendations were made in a practical approach by presenting the solution in the form of a flow chart. This model will enable the Maintenance Managers, Inventory Managers and Maintenance Planners to identify critical equipment, optimise maintenance schedules and plan spare parts purchasing more accurately.

- Description: The Natal Valley is a ~1000 km long, elongated depression in the seafloor, located within the south-west Indian Ocean, between the coastline of south-east Africa and the offshore aseismic Mozambique Ridge. Knowledge of its present-day crustal structure is important to reconstruct the Gondwana supercontinent break-up history and the concurrent opening of the Indian Ocean, which started during the Jurassic, some ~180 – 150 million years ago. Major geological events relating to this supercontinent break-up including continental rifting, magmatism, the emplacement of extensive oceanic flood basalt as submarine plateaus, vertical processes associated with tectonic uplift, flexural subsidence of the margin and relative global sea-level change are recorded within the crust underlying the south-west Indian Ocean. Although these events have been well modelled, fundamental questions remain regarding the nature and tectonic structure of the crust. Today, the Natal Valley region represents a frontier for geophysical exploration. Early attempts at imaging the crust beneath the seafloor within the south-west Indian Ocean made use of now primitive seismic reflection data acquisition and processing techniques available to them at the time (1960’s - 1970’s). Considering the advancements made in marine seismic reflection imaging, these vintage datasets lacked the horizontal and vertical resolution necessary to most accurately account for and describe features of the upper crust underlying the northern Natal Valley. This study is based on the acquisition, processing and preliminary interpretation of a newly acquired, regional seismic reflection profile, Profile Mz5-007, acquired across the northernmost region of the Natal Valley during the PAMELA-Moz5 cruise in 2016. The methods of marine seismic reflection data acquisition, processing and interpretation are described. The seismic reflection data presented in this dissertation provides a regional-scaled appraisal of the upper crust underlying the northern Natal Valley for the first time. The imagery allows a comprehensive description of crustal structures and features from the very northern Natal Valley, close to the Mozambique coastline, southwards into the southern Natal Valley offshore of Durban. The findings presented here support the notion that the crust underlying the northern Natal Valley experienced roughly N-S orientated trans-tensional stresses in relation to the breakup of West Gondwana. At least two major phases of volcanism are imaged within the seismic stratigraphy. The lower-most event underlies the Limpopo Fan in the northernmost regions of the Natal Valley at a depth of 2 seconds TWT and is interpreted as a seismic expression of the upper surface of the Lower – Middle Jurassic Karoo LIP. The progressive disappearance of this horizon towards the south coincides with the emergence of a second, overlying, as yet unreported volcanic horizon, which extends southwards throughout the Natal Valley. On the basis of its regional distribution, spatial relationship with the underlying event boundary and its deformation history, this volcanic horizon is interpreted to represent a series of basaltic lava outpourings during the Lower Cretaceous, initiated in response to trans-tensional crustal deformation associated with the breakup of West Gondwana. In addition to these two major phases of flood basalt outpouring, a number of localized volcanic flows are imaged throughout the stratigraphy, most notably over the Central Terrace. In addition, at least four major unconformities are identified, all of which are well developed within the Limpopo Fan. One of these is interpreted to represent the well-developed Mid-Cretaceous hiatus in sedimentation, providing a relative seismo-stratigraphic constraint to overlying and underlying seismic units. A review of the structural elements of the crust reveals how the northern Natal Valley is partitioned into two sub-basins separated by a prominent basement high, the Central Terrace, imaged across the central portions of Profile Mz5-007. To the north of the Central Terrace, structural deformation appears largely extensional, characterized by a large (~37 km wide) asymmetrical depression directly to the north of the Central Terrace and only minor structural faulting. To the south of the Central Terrace, trans-tensional stresses associated with withdrawal of the Falkland Malvinas Plateau have deformed the upper crust into a series of apparently southwards tilted crustal blocks, producing a series of deep (3.5 s TWT) half graben-like structures, within which syn-rift fill has an apparent dip towards the south. There is evidence to suggest ongoing reactivation of these fault structures. This zone of deformation is shown to bear resemblances to the faulting mapped onshore of the Kwa-Zulu Natal coastline, providing reason to consider the two regions as a continuous zone of deformation associated with the withdrawal of the Falkland-Malvinas Plateau during the breakup of West Gondwana. Furthermore, a number of post-sedimentary intrusive features are imaged, the largest of which is the Naude Ridge; a large pinnacle-like feature which has penetrated the upper crust towards the southern limit of the profile. This feature corresponds to an abrupt change in seafloor depth and upper crustal structure, suggesting that this feature may mark the transition between subsided continental crust interpreted to underlie the northern Natal Valley to the north and oceanic crust known to underlie the southern Natal Valley to the south.

This zone of deformation is shown to bear resemblances to the faulting mapped onshore of the Kwa-Zulu Natal coastline, providing reason to consider the two regions as a continuous zone of deformation associated with the withdrawal of the Falkland-Malvinas Plateau during the breakup of West Gondwana. Furthermore, a number of post-sedimentary intrusive features are imaged, the largest of which is the Naude Ridge; a large pinnacle-like feature which has penetrated the upper crust towards the southern limit of the profile. This feature corresponds to an abrupt change in seafloor depth and upper crustal structure, suggesting that this feature may mark the transition between subsided continental crust interpreted to underlie the northern Natal Valley to the north and oceanic crust known to underlie the southern Natal Valley to the south.

- Description: Small and Medium sized Enterprises (SMEs) are a vital driver to the world economy. They provide more than 60% of overall employment globally and approximately 80% of jobs in developed economies. This segment however remains underserved by banks who have struggled to serve SMEs effectively. Nevertheless banks are still perfectly placed to capture the needs of SME customers and to provide them with greater value adding services that address their needs. However, this must be done in a cost-effective manner to ensure long-term portfolio and banking profitability. SME Banking faces several challenges centred on the high cost to serve and profitability. For the banking sector to overcome these challenges and still meet increasing and changing customer needs, significant investment in digital technology is required. The literature reviewed identified that in order to unlock the revenue potential embedded within the SME segment; banks need ground-breaking solutions to solve their revenue and profitability conundrum. This study mentions that such solutions will need to be focused around placing banks as market enablers, by way of providing SMEs with a growth platform and not just financial transaction services. The study also identified a hybrid service delivery model and a digital ecosystem approach to SME banking as being pivotal to unlocking the revenue potential embedded within the segment. Through a digital ecosystem approach, banks can leverage their intra and inter banking network to assist SMEs to grow their businesses. In the process, this will serve as a way of increasing penetration into this underserved segment. In addition, such an approach to banking necessitates an acceptance of how interconnected business relationships have the capacity to enable business growth and subsequently to address SME banking risk. To also consider that banks in South Africa continue to view SMEs as being too risky and costly to serve. This study attempts to address this perceived riskiness by presenting a service delivery framework, which consists of key factors that would influence the revenue potential of the SME segments of Commercial Banks in South Africa. The empirical part of the research evaluated banking official’s awareness and understanding of key concepts that is likely to influence their views with regards to the revenue potential of the SME market.

- Description: Social media have become the preferred method of communication for individuals, organisations and even governments. These technologies have become ingrained in our everyday lives and have changed the way we communicate, collaborate are informed of recent happenings around the world. Social media websites are reported to be the most popular around the world. In the government sphere, social media is purported as a technology that will revolutionise citizen participation, service delivery and government-citizen interactions. Accordingly, governments around the world are steadily implementing social media in a bid to meet citizens’ demand for immediate and constant access to information, as well as increased opportunities to participate in government. Public participation has become an important focus area for government which could be used to effectively engage citizens and foster citizen trust. The United Nation’s E-government survey reports the presence of 125 countries on social media platforms. Despite the increased use of social media by governments, consensus among researchers is that governments need guidance on how to use social media effectively to achieve the potential benefits proposed by these technologies. Many social media adoptions by governments have been deemed as experimental; no formal action plan was designed, and many government employees are expected to learn social media use on-the-job. The aim of this research was to investigate and propose a social media model for public participation to leverage the opportunities provided by social media and present an effective and structured approach towards public participation. The research was designed as a mixed methods research using a case study based in the Eastern Cape Province of South Africa. The research involved a survey of citizens in the selected municipality based on the Uses and Gratifications Theory, interviews with employees responsible for social media in said municipality and a contents analysis of the existing social media pages of the municipality. The model was developed from the findings of the survey, interviews and existing literature. The implementation of the model was done in the Nelson Mandela Bay Municipality. The municipality appointed a social media champion responsible for obtaining support from top management and politicians within the municipality. Additional staff were added to the social media team and formal social media training was provided to the team. An official social media strategy was drafted and at the time of writing, needed to be approved by top management. The proposed model was operationalised within the Nelson Mandela Bay Municipality. This research makes several contributions to the E-government and social media fields in South Africa. The major contribution is the provision of guidance for South African municipalities to implement and use social media in an effective manner to achieve public participation. The research provided a phased approach to social media implementation that eliminates ad hoc experimentation and ensures the municipality’s social media activities are effective. The development of the model was based on the characteristics of the municipality and its citizens derived from the interviews and survey carried out. There are five phases in the model; Initialisation, Setup, Organisation, Institutionalisation and Maintenance. The model can be thought of as a guideline, and as such municipalities should adapt the implementation of the model to fit their organisational characteristics. The social media model will assist municipalities to determine the resources, tools and tactics to enable them to implement social media effectively, which will result in an improved engagement and participation process with citizens, and thereby foster trust.
