- Description: The purpose of this treatise was to analyse selected clauses in selected double taxation agreements with South Africa. An integrative literature review research method was used. The study commenced with an overview of double tax agreements from both an international and South African perspective. This was followed by a critical analysis of the Mutual Agreement Procedures, the Most-Favoured Nation clause and the Non-discrimination obligation. Selected court cases domestic and foreign court cases were used to illustrate the gaps that sometimes exist between revenue authorities’ and taxpayers’ understanding of the clauses being studied. An analysis was then performed of the measures and their appropriateness that South Africa can implement to close the loopholes arising from the selected clauses. This was informed by the action plans suggested by the OECD and the Davis Tax Committee on base erosion and profit shifting. The study then concluded with a synopsis of the key findings of the selected clauses and their recommendations. Finally recommendations were made for areas of further research which might assist in closing the loopholes arising from the words employed within double tax agreements and the intention of the legislature/the executive can be closed.

- Description: The purpose of the treatise was to examine the administrative issues that have arisen related to the implementation of the Health Promotion Levy (HPL) in South Africa, and to identify solutions to these issues. The study commenced with a review of what the HPL is and how it is levied. This was followed by a comparative analysis of issues that have been experienced by four countries, as well as any potential issues that have been identified by the four countries. The HPL is often referred to as sugar tax in many jurisdictions, and was referred to as HPL for the purposes of this treatise. A review was then performed of the solutions that were implemented by these countries in responding to the administrative issues that were identified, as well as guidelines issued by the World Health Organisation for the implementation of this levy. The likelihood of these issues arising in South Africa’s implementation of the Health Promotion Levy was examined based on these comparisons. It was found that the issues experienced by other countries in the implementation of the HPL have been experienced in South Africa, or may be relevant in a South African context. Following this, the solutions implemented by other countries and recommended by the World Health Organisation were analysed to determine if these solutions are practical in a South African context. Many of the solutions implemented by the countries analysed, are relevant in a South African context and have, in fact, already been implemented in South Africa The conclusion reached was that South Africa has been successful in administering the implementation of the HPL and that the administrative costs of the implementation and administration of the HPL are outweighed by the benefits of the health awareness raised by the implementation of the HPL.

- Description: Information and communication technologies (ICTs) have made life much easier for many people but have also brought many dangers to the world. School learners are amongst the users of ICT who are becoming cyber citizens. This age is good at exploring new things, with a growing number of school learners having access to ICT devices, such as mobile phones, tablets and desktop computers. This is due to the affordability of mobile phones, which they normally receive as gifts from their parents. Due to easy access of ICT, school learners can now access cyberspace which offers them many advantages and benefits. Such advantages and benefits include having a platform to socialise, improved and ease of access to information as well as improving their learning. Despite these benefits, school learners (primary school learners in particular) are prone to falling victim to a range of cyber risks and attacks since cyberspace is an unregulated platform that poses many potential dangers Common cybersafety threats associated with school learners include cyberbullying, sexting/“sextortion”, engaging with strangers, accessing inappropriate content and being exposed to a breach of privacy. Because the cybersafety of children, especially primary school learners, is often compromised, there is a need to protect them from the threats associated with ICT. However, protecting children from the aforementioned cybersafety threats is complicated because access to cyberspace is no longer confined to the home computer, but has extended to mobile phones, which are even more pervasive. Therefore, it is essential for school learners to be educated on how to protect themselves and their information in the virtual computer world. A number of developed countries like Australia, New Zealand, Canada, United States of America (USA) and United Kingdom (UK) have included cybersafety education in their school curricula. Similarly, the rapid growth of the Internet around the world, allowed some countries in Africa to take the initiative to start implementing cybersafety education in schools including Mauritius, Tunisia, Kenya, Ghana, Mozambique, Cameroon, Egypt and Rwanda. Countries like Uganda, Sudan, Morocco and South Africa are still facing challenges in this aspect. This study is focused on the cybersafety of primary school learners in the South African context.

- Description: Family businesses are the backbone of many economies around the globe and are believed to constitute over two-thirds of all businesses worldwide. For nearly 300 years, the Southern African economy has been developing as a consequence of the contribution of family businesses to the region’s economy. Despite their importance to the economies of countries, their overall failure rate remains high. Given the important economic and societal contribution that family businesses make, their survival rates are a matter of concern. As far as can be established, little research has been conducted among indigenous African family businesses. The research done to date lacks depth in terms of the topics covered and the countries sampled. The majority of studies on family businesses have been done in European, American and Asian settings. Notably, the research project on Successful Transgenerational Entrepreneurship Practices (STEP) has investigated transgenerational entrepreneurship among family businesses around the world. The STEP project proposes a theoretical framework, known as the STEP framework, which to date has not been applied to the indigenous African context. There is a great need for deeper insights into, and an increased understanding of the practices implemented among indigenous African family businesses that have survived across the generations, and of the context in which these businesses operate. Therefore, the primary objective of this study is to explore and describe the factors that influence the transgenerational potential of indigenous African family businesses so as to assess the appropriateness of an existing non-African framework, namely the STEP framework, and to reconfigure it for the African context. The STEP framework proposes that various contextual factors influence both the entrepreneurial orientation and the familiness resource pools of family businesses, which in turn influence each other, and ultimately the transgenerational potential of the family business. The underlying theory applied in the study is Hofstede’s Cultural Dimensions model. Hofstede’s model provides theoretical support for the belief that the context in which a theory or framework is applied has a big influence on the successful application of such a framework. Therefore, a need exists to contextualise the STEP framework to the context in which it is being applied. An interpretivist research paradigm and a qualitative methodological approach were deemed the most suitable for the current study, as this paradigm and approach enabled the researcher to address the dynamics and invisible issues within family businesses. The current study adopted a multiple case study methodology. Adopting this methodology allowed for a deeper understanding of the object of interest. The three cases were systematically selected, using purposive sampling, to ensure that a credible and indicative sample was obtained. The criteria used for selection were based on the STEP project guidelines and the three businesses selected were from South Africa, Zimbabwe and Botswana, of indigenous African heritage and have showed sustained growth and success since their establishment. The reason for these selection criteria was to ensure that the study appropriately addressed the defined research objectives and the gap in the body of knowledge on transgenerational entrepreneurship in the African context. The instrument used to guide the key-informant interviews in this research was a semi-structured interview schedule adapted from the STEP project interview schedule. Once all the data was collected, a combination of directed content analysis and explanation building was used to analyse the data. A framework for enhancing the transgenerational potential of indigenous African family businesses is proposed in this study, based on the practices adopted by the successful indigenous African family businesses which participated. The framework developed adapts the STEP framework for the indigenous African family business context. As in the STEP framework, the framework proposed for indigenous African family businesses highlights several external contextual factors as influencing both the familiness resource pools and the dimensions of entrepreneurial orientation. In the context of indigenous African family businesses, the external contextual factors most influential are the philosophy of Ubuntu, the collectivist national culture, as well as the community and extended family commitments. The external contextual factors, namely, the business environment and the industry in which the business operates, were found to be particularly influential on the entrepreneurial orientation displayed by the participating family businesses. All eight familiness resource pools, as well as the five dimensions of entrepreneurial orientation as proposed in the STEP framework, still form part of the framework proposed for indigenous African family businesses. However, for some the nature thereof differed somewhat from the original descriptions. Therefore, the original names were adapted to better describe these concepts as applicable to an indigenous African family business context. The proposed framework supports the multi-dimensional nature of performance outcomes among indigenous African family businesses. It proposes that in an indigenous African family business context, entrepreneurial performance outcomes are important to the extent that they contribute to achieving the financial performance outcomes, while the financial performance outcomes are important to the extent that they contribute to achieving the social performance outcomes. This study contributes to a greater understanding of successful indigenous African family businesses and their best practices, specifically an understanding of the practices adopted with regards to the familiness resource pools and entrepreneurial orientation. Furthermore, this study has expanded on the understanding of paternalism in that it has provides greater clarity on the nature of this leadership style, as well as the positive outcomes associated with it, in an African context. The study also has significance for educators, who can incorporate the lessons learned from it into their entrepreneurship and family business teaching.

- Description: The success of business firms operating in the retail industry is largely dependent on the performance rendered by their supply base. Choosing the incorrect supplier could have dire consequences for the retailer’s performance, as suppliers are generally considered an extension of the retailer. Organisations base their operational expertise on the key performance objectives of cost, service, quality, speed, dependability and flexibility, which becomes the basis of their selection criteria when evaluating suppliers. The primary objective of this study was to develop a framework that guides retailers in their supplier selection process with the ultimate goal of formulating strategies to improve Nelson Mandela Bay’s (NMB’s) retail performance. In support of the primary objective, it was necessary to identify the current supplier selection criteria used in the NMB retail industry and the challenges that retailers face when selecting suppliers. The study set out to assess the effects of utilising established supplier selection criteria on retailers’ performance, as well as to identify strategies that retailers should employ to improve their performance. A quantitative research approach was utilised to collect data from a sample of 248 retailers and procurement and logistics managers. The empirical findings of the study identified flexibility, timeous delivery and reliability as the most important supplier selection criteria identified by retailers in NMB. The findings also revealed that utilising established supplier selection criteria has a significantly positive effect on retailers’ performance. Lack of collaboration between suppliers and retailers, lack of transparency between suppliers and retailers and suppliers’ limited knowledge of the criteria by which they are judged were identified as the most significant challenges facing retailers in NMB. The empirical findings also identified an increase in a retailer’s competitive advantage and revenue as the benefits of utilising supplier selection criteria to improve a retailer’s performance. The conclusions and implications of the empirical findings are provided and recommendations made. The study advances a framework to assist in guiding the retailers and procurement and logistics managers, retail researchers and policy makers when selecting suppliers. The study suggests that retailers should identify the most important supplier selection criteria, inform potential suppliers of the importance v of those criteria, select suppliers based on those criteria and utilise those criteria to evaluate the suppliers’ performance.

- Description: Many organisations, especially public sector organisations, are required to ensure that they are able to continue with their operation in cases of major disasters that affect the organisations. In the same light, the South African Revenue Services (SARS), being a quasi-government organisation, faces a similar phenomenon. The main purpose of conducting this research was to explore a problem in depth that was identified at the SARS. SARS does not have a comprehensive business continuity plan. The study therefore examined possible techniques or actions for ensuring information and communication technology (ICT) readiness and business continuity, explored various frameworks and policy documents which will assist public entities with readiness for business continuity, and identified frameworks that will assist SARS in implementing an effective ICT readiness for business continuity. The study adopted the design science research approach and aspects of design science research in information systems. Data gathered through the questionnaire instrument was used to design a framework that can be adopted at SARS to enhance ICT readiness for business continuity. The research findings show the importance of effective business continuity management (BCM) and a framework that can be used to implement an effective BCM.

A housing affordability and tenure of choice quantum deliverable model in South Africa

- Description: The aim of this research was to develop a model that practically determines the tenure of choice and affordability of households in South Africa, which will thus help towards informed decision making by analysts and housing officials. Presently, there is no clear systematic means (except for simplistic ratios) of determining the degree of the effect of changes in the housing market (such as implemented policies) on the tenure of choice and affordability decisions of households. The research set out to improve upon the usage of ratios by basing its analysis on the theoretical underpinnings of both user costs of occupancy and an assumption of endogeneity between tenure of choice and affordability. The research used the general household survey data from Statistics South Africa for the analysis and validation. Generalized joint binary regression (on assumption of endogeneity between tenure of choice and affordability) was used as a check against the user costs of occupancy modelling. An independent market analysis carried out showed that South Africa has consistently faced increasing problems of acute housing shortages and housing affordability. Never the less, apart from subsidy programs, the option to promote renting, coupled with use of innovative building technologies showed promise of significantly alleviating these problems. More living space is especially more vital than ever, amid the current crisis of COVID-19 pademic. Statistical tests indicated strong evidence suggesting that the developed user costs of occupancy model (dynamic tenure model) is reliable at correctly recovering the tenure statuses of the households, with its recovery rates being better than those of the regression model. Both models provided useful unique, but different insights into the housing market and also correctly predicted the behavioural patterns of South African housing markets, such as significantly worsening affordability, and a market that is biased towards home ownership. The analysis also showed that affordability and tenure of choice were significantly affected by locational factors, household characteristics (such as race and age of household head), and most significantly, the age of the household head (which is a proxy to household income). The research successfully met its goal of model building but also recognized the need to merge these two models (dynamic tenure model and the regression model) into one model for more comprehensive housing related analysis. The research also recognized a need to fully operationalize the optimization, Monte Carlo and parallelization modules in order to improve the practical usefulness and effectiveness of the model. The significance of the study is that it it underpins the basis for proper tenure and affordability analysis, by assuming endogeneity between the two (2), and provides a modelling framework based on these criteria, that are useful for meaningful housing market analysis.

The research also recognized a need to fully operationalize the optimization, Monte Carlo and parallelization modules in order to improve the practical usefulness and effectiveness of the model. The significance of the study is that it it underpins the basis for proper tenure and affordability analysis, by assuming endogeneity between the two (2), and provides a modelling framework based on these criteria, that are useful for meaningful housing market analysis.

- Description: In the past 16 years, the use of League Tables and Rankings (LTRs) as a tool to rank or measure the performance of Higher Education Institutions (HEIs) has grown in popularity. As a global practice, LTR outcomes are influencing how policies are developed and implemented within the Higher Education (HE) sector. Studies indicate that based on individual information requirements, HE stakeholders are using LTRs to compare HEIs with each other and make informed comparisons and decisions. University directors use LTRs as a basis for institutional strategic planning, reputation building and policy making, while students use LTRs to compare HEIs and make university of choice decisions. Further studies confirm that governments use LTRs for national higher education policy making, university funding, foreign partnerships and resource allocation. Globally and at a national level, the higher education sector has witnessed policy and structural changes, many of which are due to the increase in the use of international rankings and league tables. Despite the opportunities presented by participating in the production of and using LTRs, the ranking practice is contentious. Amongst the issues disputed by the HE stakeholders are the methodologies and criteria used in the production and publication of LTRs. Higher education experts argue that LTRs tend to favour institutional research output and ignore the teaching and learning function of HEIs. As a result, the ranking criteria differ across the higher education ranking institutions and their publication outcomes, which causes skepticism across the HE sector. Research indicates that these ranking criteria are often discussed from the standpoint of governments, the higher education management and the ranking institutions producing these LTR publications. The opinions of the students on the suitable ranking criteria used by ranking institutions lack. This study aims to address that gap. This study investigates the applicable criteria for ranking HEIs in South Africa, from the perspective of students. Building on the existing ranking criteria for three global and popular ranking institutions namely, Academic Ranking of World Universities (ARWU), Times Higher Education World University Ranking (THEWUR) and Quacquarelli Symonds World University Ranking (QSWUR), the study poses the question; “What framework can be used to rank HEIs in South Africa, from a student’s perspective?” The study argues that although some HEIs in South Africa have in the past and most recently appeared in the global LTRs, the current choice of ranking criteria fails to consider the perspectives of the students, who are major consumers of LTRs and important stakeholders in the HE sector. A positivistic research method was used, based on a review of literature on the current ranking criteria for the selected global ranking institutions. An empirical study was conducted amongst students in a South African Comprehensive University. An online survey was distributed through convenient and snowball sampling, where the students were requested to participate in the survey and share the questionnaire link with others. Eight hundred and eighty six (886) responses were received and used for the data analyses of this study.

- Description: Information is a critical asset in any organisation and its management, including the associated technological channels, requires the attention of decision-makers to ensure that information assets are utilised for the intended purposes. Therefore, decision-makers need to have appropriate governance oversight on technology that produces information and information itself. Over the years, the governance of ICT has been adopted in the public sector given the fact that state funding received from tax collections is utilised to invest in IT solutions with the intention of expediting service delivery and increase productivity. The purpose of this treatise was to identify the root causes of why the department is not implementing Corporate Governance of ICT successfully despite the fact that most good controls do exist. The research revealed that there is insufficient budget to implement ICT projects coupled with inadequate ICT staff to implement ICT strategy. Furthermore, it cited a lack of ICT governance skills with ICT Strategic Committee members who are tasked with pioneering ICT governance. This weakness relates directly to other identified weaknesses such as end-user resistance to adopt ICT projects and a lack of project management function in the department.

- Description: The internationalisation of higher education has become an inevitable focus in the modern day higher education sector. This focus is due to the interconnectedness of society, which is driven by globalisation. The ever-changing landscape of the current global higher education sector has further placed emphasis on self-funding and the corporatisation of higher education institutions (HEIs). This has created competitiveness in the sector for local and international students, which has led to institutions globally and in South Africa, being tasked with the responsibility of being agents of internationalisation. The concept of higher education internationalisation involves internationalisation of the curriculum, cross-continental partnerships, the increase in mobility of staff and students, educational programmes, innovative ways of delivery as well as the need to be globally competitive. Students themselves view international study important as it provides them with a global outlook and international experience. The increased competitiveness in the higher education sector and the need for HEIs to become more autonomous and self-funded, has amplified the need to recruit international students who generate additional income. Furthermore, the strategy to recruit international students has evolved and transformed into a customer-driven strategy to meet the needs of the knowledge economy. To recruit international students, HEIs must invest in marketing and recruitment strategies, which build brand awareness and attract a diverse student body. This study investigates the development of a strategic university of choice model that can assist South African universities in the recruitment of international students by focusing on the factors, which influence a student’s university of choice. This was realised firstly by conducting a pilot study investigating the factors which influence the university of choice of students studying in South Africa. Secondly, the findings of the pilot study, combined with appropriate literature studies were used to develop a questionnaire to aid in determining the factors which influence the university of choice of international students studying in South Africa. Lastly, the findings of the questionnaire were used to draw conclusions and develop a proposed strategic model to promote the university of choice decisions among international students studying in South Africa. This thesis is an exploratory, mono-method quantitative study, which consists of literature reviews and surveys in a cross-sectional timeframe. The literature reviews were conducted on secondary sources to identify the factors that influence university of choice, as well as the marketing and recruitment trends within higher education. The empirical study consisted of a Pilot Study Survey and a Main Study Survey. The measuring instrument was compiled from existing surveys and literature studies. The findings of the Main Study Survey identified the following main factors of influence on university of choice: academic programme, academic quality, visa requirements, country/city attractiveness, English language, financial, International Office, student life, safety and security, university location and university reputation as main factors of influence. Within these main factors, various sub-factors were identified. The findings further illustrated that certain factors were more consultative in nature and provided information, which aided in the decision-making process. These factors are: motives to study/choose a programme, country attributes and influences/recruitment methods. Additionally, a third set of factors deemed to subconsciously influence the student’s decision-making process were identified as background of the student, study level and student type. The study contributes theoretically to Stakeholder Theory and Means-End Theory. Prospective students, who are higher education stakeholders, have diverse information needs and expectations, which will be met through the use of the proposed strategic model. Furthermore, the prospective students’ input will aid in the development of focused, targeted and cost-effective marketing and recruitment strategies, which will in turn meet the needs of universities to recruit a diverse student body.

- Description: Information technology (IT) is widely used in South African municipalities as a tool for enabling business processes and therefore its design and implementation are critical to municipalities delivering on their core mandate of delivering services to their communities. The implementation of IT relies on the adoption of sound IT governance practices, whose outcome is to ensure that municipalities derive value from the use of IT and minimise the risk associated with it. However, the implementation of IT governance has proved to be challenging in most municipalities. This research sought to devise a strategic approach to the effective and viable implementation of IT governance in municipalities in South Africa. The research was carried out by adopting a design science research approach, which is increasingly being used for studies in the IT discipline as it assists in solving problems through the design of innovative artefacts, in this case a strategy for the implementation of IT governance. To address the objectives, the research was carried out through case studies of South African municipalities which enabled a detailed investigation of phenomena in its natural context. The data was collected by means of mixed methods consisting of a literature review, a survey and semi-structured interviews. A literature review connected to the research problem was done in order to identify the present state of the issues and how they have been confronted. A survey was sent out to municipalities, institutions and individuals with a mandate to support municipalities, while semi-structured interviews were conducted in five municipalities, government departments and regulatory bodies. A thematic analysis of the data collected was performed which led to a diagnosis of the issues. These include inadequate IT infrastructure; lack of coordinated external support; inadequate IT skills; lack of strong and committed IT leadership; poor IT controls; and fragmented planning. Guiding policies and a set of coherent actions for solving the issues were developed. This culminated in the devising of a strategy for the coordinated implementation of IT governance in municipalities. The primary contribution of this study is the formulation of a strategy for the sound implementation of IT governance in South African municipalities. The research contends that by identifying the strategic issues facing municipalities and implementing the proposed actions, most of which fall outside the municipalities, a new contribution to knowledge has been made. Accordingly, the strategy facilitates the development of plans that address the root causes of the poor implementation of IT in municipalities.

- Description: Surface roughness prediction is a crucial stage during product manufacturing since it acts as a quality indicator. This investigative research thesis presents an online surface roughness prediction, based on the Adaptive Neuro-Fuzzy Inference System (ANFIS) model during Ultra-High Precision Diamond Turning (UHPDT) of Rapidly Solidified Aluminium (RSA-443) using water and kerosene as coolants. Based on the Taguchi L9 orthogonal array, the cutting parameters (spindle speed, depth of cut and feed rate) are varied at three levels. Acoustic Emission (AE) signals are detected during the UHPDT process using a piezoelectric sensor. Spindle speed, depth of cut, feed rate, AE root mean square, prominent frequency and peak rate are considered as model inputs in this thesis. The experimental results reveal that a better surface finish is obtained using water coolant in comparison to kerosene coolant. Mean Absolute Percentage Error (MAPE) based comparison between ANFIS and Response Surface Method (RSM) is carried out. In this study, the ANFIS model has a prediction accuracy of 79.42% and 69.40% on water-based and kerosene-based results respectively. The RSM model yields higher prediction accuracies of 98.59% and 95.55% on water-based and kerosene-based results respectively.

- Description: A psychobiographical study is an exploration of a unique individual’s entire lived life through a psychological lens. The aim of the study was to explore and describe the personality development of Aileen Wuornos within her socio-historical context by applying Erikson’s Theory of Psychosocial Development. Aileen Carol Wuornos was an American serial killer who murdered seven men in Florida between 1989 and 1990 by shooting them at point blank range. Wuornos’s life was marked by a difficult formative environment, maternal abandonment, and adoption by her grandparents. Wuornos continued to experience physical, emotional and sexual abuse at the hands of family members, friends and the community. Wuornos lived her life focusing on survival, and started to engage with petty crime and prostitution to do so. Her patterns escalated to include more serious criminal behaviour, culminating in serial murder. Wuornos was selected for this study using nonpropability purposive sampling. She was selected based on the researcher’s curiosity of her life events and experiences that led her to commit serial murders. Data was collected through a variety of primary and secondary sources on Wuornos and it was analysed using Miles and Huberman’s three steps process of data analysis, which includes data reduction, data display, and conclusion drawing and verification. The findings of this study indicate that Wuornos experiences severe difficulties in renegotiating the seven stages proposed by Erikson’s Theory of Psychosocial Development, and all the ego strengths that she developed were seriously delayed.

- Description: The 2006 International Telecommunication Union (ITU) Radio World Conference treaty concluded that all countries should migrate from analogue to digital terrestrial television by June 2015, starting with region one countries, comprising Africa, Europe, the Middle East and the Republic of Iran (Agona & Otim, 2012). South Africa, as part of region one, developed a migration policy, Digital Terrestrial Television (DTT) regulations, and initiated a process of migrating from Analogue Terrestrial Television (ATT) to Digital Terrestrial Television (DTT) to meet the deadline. South Africa, however, missed the June 2015 deadline due to a number of challenges, including a lack of infrastructure readiness, South African citizens’ unawareness and government politics, and the deadline has since been extended by ITU to July, 2020 (African Telecommunications Union, 2018). The purpose of this research is to explore the technology adoption model (TAM) to address challenges associated with digital terrestrial television migration, and analyse the readiness of South Africa to migrate. TAM is a model used by researchers to understand the behavior and perception of users in new technology adoption (Fayad & Paper, 2015). Quantitative research is conducted to determine the relationship between dependent and independent variables. The research was undertaken through the use of an online questionnaire with a sample of South African citizen's. A sample of 60 -150 citizens, comprising middle and senior managers of the broadcasting industry was used for the purpose of this research. Digital television offers many benefits for broadcasters, network operators, spectrum regulators, and consumers. In most countries, the transition was slower than expected, even though most European countries managed to migrate. The digital migration is not an easy transition and analogue switch-off can also be much more difficult. Studies have shown that analogue switch off (ASO) needs to be carefully planned and well budgeted for, and it also needs a good publicity campaign which must involve all relevant stakeholders, such as broadcasters, viewers, manufacturers, network operators, manufacturers and retailers. Even though studies conducted previously identified obstacles of digital migration to include; a) lack of awareness b) lack of information, c) influence of politics and d) influence of corruptLack of information and influence of corruption seem to have strong correlation with DTT migration, so these are areas that need additional attention. Studies have shown that the African continent is struggling with meeting the digital migration deadline and is progressing very slowly. It is therefore advisable for the African continent to do a thorough analysis of how other countries managed to migrate successfully. Most African countries are struggling with the migration of television broadcasting from analogue terrestrial television to digital terrestrial television. This is caused mainly by lack of information and lack of awareness. Even though most South African people have heard about digital terrestrial television, they are not equipped for the migration. To sensitise viewers, as major stakeholders of digital migration, will play an important role. It is important that the South African Government should get a buy in from all relevant stakeholders as soon as possible. Broadcasters, including the national signal broadcaster (SABC), community broadcaster, commercial broadcasters, Sentech LTD and government should coordinate in establishing vigorous DTT awareness campaigns to educate viewers. These will encourage buy in from viewers and, as a result, drive dual illumination costs down, saving the county money. South Africa need to fast-track the implementation of digital migration to prevent incurring financial losses due to supporting two terrestrial television networks. Even though studies show that most challenges associated with digital migration are common throughout the world. It would, therefore, be logical for South Africa to take the best practices from developed countries that have successfully migrated and are already broadcasting in digital. Lastly, digital terrestrial television migration is dependent on set-up box approval, manufacturing and affordability. In order to ensure that set-up box prices are affordable for South African consumers, it is recommended that these boxes must be 100% manufactured in South Africa. This will drive costs down and ensure good, total quality assurance. It will also mean that the required skills are developed and maintained locally to position South Africa better for future technology developments. Successful digital television migration would be a great milestone for South Africa.

South Africa, as part of region one, developed a migration policy, Digital Terrestrial Television (DTT) regulations, and initiated a process of migrating from Analogue Terrestrial Television (ATT) to Digital Terrestrial Television (DTT) to meet the deadline. South Africa, however, missed the June 2015 deadline due to a number of challenges, including a lack of infrastructure readiness, South African citizens’ unawareness and government politics, and the deadline has since been extended by ITU to July, 2020 (African Telecommunications Union, 2018). The purpose of this research is to explore the technology adoption model (TAM) to address challenges associated with digital terrestrial television migration, and analyse the readiness of South Africa to migrate. TAM is a model used by researchers to understand the behavior and perception of users in new technology adoption (Fayad & Paper, 2015). Quantitative research is conducted to determine the relationship between dependent and independent variables. The research was undertaken through the use of an online questionnaire with a sample of South African citizen's. A sample of 60 -150 citizens, comprising middle and senior managers of the broadcasting industry was used for the purpose of this research. Digital television offers many benefits for broadcasters, network operators, spectrum regulators, and consumers. In most countries, the transition was slower than expected, even though most European countries managed to migrate. The digital migration is not an easy transition and analogue switch-off can also be much more difficult. Studies have shown that analogue switch off (ASO) needs to be carefully planned and well budgeted for, and it also needs a good publicity campaign which must involve all relevant stakeholders, such as broadcasters, viewers, manufacturers, network operators, manufacturers and retailers. Even though studies conducted previously identified obstacles of digital migration to include; a) lack of awareness b) lack of information, c) influence of politics and d) influence of corruptLack of information and influence of corruption seem to have strong correlation with DTT migration, so these are areas that need additional attention. Studies have shown that the African continent is struggling with meeting the digital migration deadline and is progressing very slowly. It is therefore advisable for the African continent to do a thorough analysis of how other countries managed to migrate successfully. Most African countries are struggling with the migration of television broadcasting from analogue terrestrial television to digital terrestrial television. This is caused mainly by lack of information and lack of awareness. Even though most South African people have heard about digital terrestrial television, they are not equipped for the migration. To sensitise viewers, as major stakeholders of digital migration, will play an important role. It is important that the South African Government should get a buy in from all relevant stakeholders as soon as possible. Broadcasters, including the national signal broadcaster (SABC), community broadcaster, commercial broadcasters, Sentech LTD and government should coordinate in establishing vigorous DTT awareness campaigns to educate viewers. These will encourage buy in from viewers and, as a result, drive dual illumination costs down, saving the county money. South Africa need to fast-track the implementation of digital migration to prevent incurring financial losses due to supporting two terrestrial television networks. Even though studies show that most challenges associated with digital migration are common throughout the world. It would, therefore, be logical for South Africa to take the best practices from developed countries that have successfully migrated and are already broadcasting in digital. Lastly, digital terrestrial television migration is dependent on set-up box approval, manufacturing and affordability. In order to ensure that set-up box prices are affordable for South African consumers, it is recommended that these boxes must be 100% manufactured in South Africa. This will drive costs down and ensure good, total quality assurance. It will also mean that the required skills are developed and maintained locally to position South Africa better for future technology developments. Successful digital television migration would be a great milestone for South Africa.

- Description: Zimbabwean teacher educators are, by the nature of their job description, required to supervise student teachers doing teaching practicum for the 0-3 home based programme. However, analysis of supervision reports of the home based programme indicates some inconsistencies in comments made by different supervisors, whereby the descriptors and supervision overall scores do not tally. It seems the supervision of the home based teacher education programme is not being implemented as expected. Hence, the purpose of this qualitative case study was to examine practices and experiences of teacher educators in the supervision of a National Early Childhood Development Home Based Teacher Education Programme (NECDHBTEP). The objective of the study was to address the key question: ‘What are the practices and experiences of teacher educators in the supervision of a NECDHBTEP. In addressing the question, the researcher used supervision as a conceptual framework. The theoretical framework which informed the study was Contextual Supervision (CS) which has its philosophical foundations in constructivism, beneficence and justice. Purposive sampling was employed in the study where two primary teachers’ colleges were selected. From each college, ten teacher educators were selected for semi-structured interviews, two focus group discussions and document analysis on teacher educators’ supervision reports. Triangulation of the data was done so as to enhance its trustworthiness. Three major themes emerged from the study, namely, the influence of home context, experience of supervisors on NECDHBTEP and supervision approaches. The study discovered that the home context, to some extent, influences supervision of the NECDHBTEP. The study also established that teacher educators face multiple challenges when supervising student teachers on the ECD home based programme. The researcher made some recommendations from the findings. One of the recommendations was for colleges to develop a specific supervision instrument for the home based ECD supervision (0-3 years category). Furthermore, there is need for Zimbabwean primary teachers’ colleges to engage in rigorous in-service training for lecturers who are not knowledgeable about the NECDHBTEP.

- Description: This study focused on a lack of an Information Technology Risk Management (ITRM) framework tailored for provincial business entities to assist with the management of IT risks. The research was aimed at developing a tailored IT risk management framework that would assist provincial business entities with an effective ITRM process. This was achieved through identifying factors that constitute an ITRM framework, determining the current IT risk management methods used in provincial business entities and assessing the IT risk culture. This research study was conducted at the Limpopo Economic Development Agency (LEDA), which is a provincial business entity in the Limpopo province. The objectives of the study were accomplished using a design science research approach which involved the creation of an artefact and design theory as a means to improve the current state of practice as well as existing research knowledge about provincial business entities and their management of IT risks. The Nelson Mandela University Design Science Methodology Framework (NMU-DSFM) was identified as the methodology to be followed to devise the contribution in the form of an artefact. It was found that the organisation does not have a positive IT risk culture. From the study of the data analysis performed, it was evident that provincial business entities have challenges associated with adequately identifying IT risks. The findings highlighted that for the proper management of risks, risk governance should be effective by ensuring that the board of directors takes the responsibility of IT risk management, and the essentials of risk governance were discussed at length. The research output for this study was a framework. The adoption of this framework may positively contribute to strengthening governance of IT risk management in the provincial business entities. Best practices were highlighted for ease of reference to determine what is required and how to implement this regarding IT risk management.

- Description: The adoption of e-learning by universities around the world has grown drastically during this time of the Fourth Industrial Revolution. Most universities implement the full utilisation of e-learning, conducting classes only by using online course delivery. Some universities still prefer a blended learning approach where classes are presented to students using both the traditional way of teaching and online e-learning platforms. Walter Sisulu University (WSU) is one of those universities that uses blended learning. The university started using this approach in 2009, through a partnership between WSU and the Netherlands for learning and teaching enhancement using e-learning. The adoption and usage of e-learning in universities is a challenge, which some researchers have investigated. This study aimed to apply the Substitution; Augmentation; Modification; Redefinition (SAMR) Model to enhance the adoption of e-learning and its usage at WSU. To obtain results, a quantitative method using approaches, such as WiseUp logs, WiseUp e-learning usage publications, WSU e-learning documents and literature, was applied. The study, according to the WiseUp logs, found that the e-learning levels at the university were low. Using the WiseUp e-learning usage publications, revealed that the university was still having some challenges regarding the low usage of WiseUp. Some of the students were not aware of the WiseUp platform as they said the system was only shown to them once and never again for continuous training. Most lecturers’ challenge was that the system was time-consuming to upload online content. This study used the WSU e-learning documents to show that the institution employed some initiatives for the adoption and usage of WiseUp, such as the LTD (Learning Teaching Development) department orientating students about WiseUp, just after their registration. The study ‘s objective was achieved, which was to apply the Substitution; Augmentation; Modification; Redefinition (SAMR) Model to enhance the adoption and usage of e-learning at WSU. The study applied the Substitution; Augmentation; Modification; Redefinition (SAMR) Model to provide a clear understanding of WSU’s position in terms of e-learning adoption and usage. The overall result from the study showed that WSU was based mostly on the first three levels of teaching and learning integration into technology, and in the enhancement level of the Substitution; Augmentation; Modification; Redefinition (SAMR) Model. The researcher noted that much still needed to be done because the usage of the system was still very low but its integration into teaching and learning was positive.

- Description: The prevalence of medical identity theft continues to increase. This is a concern for medical aid members within the South African private healthcare sector. Medical identity theft can be caused by various individuals, including internal and external role players. The deceptions involved in medical identity theft can affect medical aid members, the healthcare industry, and medical aids. Medical aid members remain unaware that they are victims of medical identity theft until they receive high medical bills or are notified by their healthcare providers. This research study focused on the lack of awareness of medical identity theft among medical aid members. The main objective of this research study was to propose best practices that can be used to address medical aid members’ awareness of medical identity theft in the South African private healthcare sector. Sub-objectives were used to achieve the main objective. The first sub-objective was to identify the parties causing and the parties affected by medical identity theft. The second sub-objective was to determine the level of medical identity theft awareness among medical aid members in the South African private healthcare sector. The third sub-objective was to identify best practices to address medical identity theft awareness. The methodology used by this exploratory research study included a convergent mixed method design, which was used to obtain quantitative and qualitative data. Data collection was completed using a literature review and a questionnaire. Data analysis and reporting made use of a qualitative content analysis, descriptive statistics, and logical argumentation. Respondents’ answers to a questionnaire about their experiences with medical identity theft provided insight into South African medical aid members’ awareness of medical identity theft. The data gathered from the respondents was analysed, and themes emerged that emphasised a lack of awareness of medical identity theft among South African medical aid members. Twenty-six pre-emptive and nine retroactive best practices to address medical identity theft awareness were identified from existing literature. These best practices were cross-referenced to determine their relevance to the list of concerns about medical identity theft that emanated from the survey completed by South African medical aid members.
