- Description: The inception of this treatise is derived simply from the identification of the current inefficient public transportation facilities in Nelson Mandela Bay. This is especially experienced in the Korsten precinct as there is a scattering of transport nodes and none of them can be particularly identified as the key transport node in the fabric. With the 2010 World Cup behind us and many infrastructures such as the Nelson Mandela Bay Stadium working as urban anchor of activity, the question still at hand is how the issue of integration between commuters and transportation can be addressed. This sets the scene for the application of an architectural resolution through the design of a transport interchange of the Korsten region. At present there are two functional informal taxi ranks that service the commuters of Korsten; the primary informal taxi node located on Attwell Street and the secondary informal taxi node on Cottrell Street. Currently they operate independently providing a service to people from different destinations, for instance Kleiner and Kempton Park. The first concern that arises is the proximity of the two taxi ranks in respect of the surrounding urban landscape. For these taxi nodes to be of service to the urban nomad they must be positioned in a more concentrated location to integrate efficiently with the urban fabric. Secondly, a thorough investigation into the informal trade is necessary to ascertain how it can enhance the street life and keep the edges activated and integrated. This treatise proposes the integration of the two independent taxi nodes with the proposed BRT system that has been implemented by the NMBM. This amalgamation would strengthen the urban landscape and create a place for the urban nomad. According to an article by Ian Ollis (2013) there is a dire need for accessible, affordable mass transport across South Africa .The bus rapid transit system was supposed to cure this woe, but implementation has been slow and mismanaged, especially in municipalities like Nelson Mandela Bay.

- 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: 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.

- 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: 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.

- 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.

- Description: Education is imperative for the economy and for the employment of the youth, particularly given the high levels of youth unemployment in South Africa. The introduction of Tourism as a school subject is perceived as a gateway to employment opportunities for unemployed people and as a means to stimulate the economy of the country. Educators, especially in South African township schools, often teach in less favourable conditions and experience many challenges which require innovative solutions. This study contributes to an understanding of the challenges faced by educators teaching Tourism, especially educators teaching in township areas in the Nelson Mandela Bay district. Of particular importance is the coping strategies used by these educators to innovatively deal with these challenges. This purpose of the study was therefore to investigate the challenges experienced by educators that teach Tourism at township high schools in two Circuit Management Centres (CMC) in the Nelson Mandela Bay district in Port Elizabeth. A qualitative research design was followed with interviews as the empirical data collecting tool. The sample consisted of 16 educators teaching Tourism to Grade 11 and 12 learners at selected schools. The data collected was analysed qualitatively, using thematic analysis. The findings of this study revealed many challenges experienced by educators of Tourism at township schools in the Nelson Mandela Bay district. The key challenges for educators related to resources, learners, the system, teachers and infrastructure. The results revealed that the educators used a variety of coping techniques to deal with these challenges. The researcher makes recommendations to the different stakeholders in education to address these challenges, as well as make suggestions for future research.

- Description: Solid waste management is particularly challenging in poor communities where socio-economic issues take precedence over keeping a clean environment. This study explores the effectiveness of community-driven waste management strategies that are implemented in Missionvale, a poverty-stricken township that forms part of the Nelson Mandela Metropole, located in South Africa’s Eastern Cape Province. The aim of this qualitative study was to explore the sustainability of the community-driven waste management practices in the township. This was premised on the understanding that having the community at the centre of waste management is important and community initiatives coupled with support from key stakeholders, yields the desired outcome: sustainable waste management. The objectives of the study were: (i) to understand what happens to the solid waste generated in Missionvale; (ii) to assess the effects of the waste and its disposal (or lack thereof) in Missionvale; (iii) to identify the challenges faced by the public in implementing waste management initiatives for sustainable development; and (iv) to establish the waste management practices in Missionvale and their effectiveness. The study found that whilst waste management is a secondary, less important issue to community respondents who are struggling with more pressing socio-economic hurdles, there are nevertheless efforts from informal waste pickers, local businesses, non-governmental entities and some individual community members to keep their environment clean. This occurs against the backdrop of the municipality’s failure in its task to provide consistent waste collection and disposal.

This has led to the emergence of e-commerce, a borderless channel, which both regionally local and international retailers have exploited. The low income market segment of e-commerce customers has been found to be apprehensive of e-commerce due to trust concerns over card-mandating payment solutions, living a large unbanked market in developing economies excluded from the e-commerce experience due to a lack of inclusive electronic payment systems. Mobile payment systems offer a source of distinctive value for both merchants and consumers, thereby increasing the e-commerce market. Due to their high level of adoption, mobile payments are capable of providing a mode for reaching new market segments and opening opportunities to bring value propositions to segments that had been unreachable in the past. This study sought to uncover the perception of consumers in an emerging economy about the use of mobile payments as a mode of remittance in e-commerce transactions. This was done by describing the factors that influence the intention to use mobile payments on internet stores. The study also investigated the effect of demographic profile on intention and use in the South African context. An online questionnaire was developed and distributed to a convenience sample of retail consumers on social media platforms, and the collected data was analysed using the SPSS statistical package. The results confirmed that compatibility, personal innovativeness, perceived trust, perceived regulatory support, and promotional benefit have a direct influence to intention to use mobile payments as a mode of remittance for e-commerce transactions. Furthermore, social influence does not have a direct influence on intention to use mobile payments in the South African context. The results also revealed that, in South Africa, the largest population group, male and female gender groups do not differ in their opinion around mobile payments. The study findings illustrate the importance of context when considering technology innovation introduction to a new market. Despite social influence not being found to be a factor for intention to use mobile payments in the South African context, the same conclusion should not be generalised as it is contextual. Recommendations and conclusions were drawn from the discussion of the findings of this research.

- Description: In many engineering sectors, sustainability is a matter of concern. The construction sector is no exception, this is because of its ability to cause harmful effects to the environment through waste generation, energy and water consumption and several other forms of damage to the environment. This has led to experts in the sustainability field calling for a need of sustainable ways of carrying out construction. In this study, information about the sustainability culture and perceptions that exist in Johannesburg was extracted from data gathered from questionnaires based on various types of qualifications, knowledge, and experience of respondents in transport infrastructure delivery. A transportation official understanding the need for sustainable transportation and wishing to do something about it may likely be unable to do so. This is due to the fact that authorities do not always have the mandate, responsibility, power, or support to make decisions that are consistent with sustainable development. It can be said that key issues to sustainability governance of transport infrastructure delivery are: a lack of policy; and a lack of awareness in government, private, and consulting organisations that focus on the delivery of transport infrastructure. The lack of sustainable infrastructure delivery models creates the need to determine the important factors impacting on the governance of sustainable delivery of transport infrastructure in Johannesburg. The matrix has revealed that there is a ‘Moderate’ familiarity and ‘Average’ understanding of sustainability governance as a concept. From the data collected, it is also clear that the current transport infrastructure in Johannesburg is ‘Moderately’ effective at serving its sustainability purpose. This study hopes to be the basis upon which ground-breaking methods to encourage sustainability governance strategies for transport infrastructure projects and further studies are predicated.
