- Description: Abstract: Mobile health (mHealth) applications for the self‐management of Type 1 Diabetes Mellitus (T1DM) are said to have great potential to assist individuals living with T1DM manage their illness more effectively. However, the lack of expert involvement in the development of these mHealth applications pose a serious risk to the consumers. mHealth applications that provide medical advice that is incorrect can harm users that rely on the mHealth application to treat their illness. For this reason, the study reviewed healthcare practitioner and scientific association involvement in the development of mHealth applications for diabetes self‐management. A systematic search comprising of specific search terms, was carried out on Google’s Play Store for mHealth applications intended for managing T1DM. These applications were then reviewed in order to determine the target market, category, developer, date that the application was last updated, price as well as whether a healthcare practitioner or diabetes association took part in the development of the mHealth application. A total of 584 mHealth applications were found on Google Play Store but only 321 mHealth applications met the criteria. In terms of the target market, 77.22% of the applications were targeted towards consumers and only 19.8% were targeted towards healthcare professionals. In terms of category, 48.51% of applications were classified under health and fitness and 45.54% under medical, leading consumers to believe that these applications are credible. In terms of expert involvement in the development of the applications, 31.68% of the applications had scientific society involvement whereas only 28.71% of the applications had healthcare professional involvement. Even though an increasing amount of consumers are turning to mHealth applications to assist them with managing their health, expert involvement in the development of mHealth applications for diabetes self‐management is insufficient. Until this issue is officially addressed, application developers should acquire expert involvement when developing these applications. If consumers can tell which applications are credible, the risks associated with using the applications to help manage their illness will be less.

- Description: Abstract: In the current economic climate, it is vital that new small and medium sized entities (SMMEs) survive the initial, developmental phase of their business. The management of these entities needs to understand what elements are important to survive the start-up phase and grow the business into an established SMME. The purpose of this study is to explore and describe the factors that impact management accounting practice and change within an SMME context. These factors are used to inform an adapted conceptual framework to provide a better understanding of management accounting practices and change within a small business context. The practical application of this framework is then demonstrated through an ethnographic case study. The study contributes to the current body of knowledge on management accounting practices and change in SMMEs by adding a framework that could be used to implement management accounting practices. , M.Com.

- Description: Abstract: The construction industry is different from other industries due to its unique characteristics. Moreover, construction projects involve different individuals and organizations which are all gathered to achieve a specific task at a specific time. However, South African construction projects sometimes face challenges relating to quality and cost overruns. This challenges can also be attributed to ineffective leadership in the South African construction industry. Therefore, it is important to evaluate leadership in the South African construction industry. Effective leadership can improve construction productivity, where its outcomes include effectiveness, satisfaction, and project success. The main objective of the study is to identify leading characteristics of construction and project managers in the South African construction industry which influence the success of construction projects. The data used in this research were derived from both primary and secondary sources. The secondary data was collected via a detailed review of related literature. The primary data was collected through a well structured questionnaire aimed at 150 projects and construction managers in the South African construction industry, 110 questionnaires were received (73% response rate). Data was analysis using statkon SPSS software, whereby frequecises and descriptive was attained. Findings from the study indicate that the main leading characteristics which influence the success of construction projects include monitoring for results, problem solving and informed judgment, team building, initiative, influencing, communication, visioning, planning and goal setting, time management, sense of responsibility, empowerment, discipline, ethics, positive expectations, conceptualization, and conflict resolution. Based on the outcomes of this study it is clear that leadership characteristics of a project and construction manager are important, to establish success from a construction project.

- Description: Abstract: Alloys containing up to four multi-principal elements in equiatomic ratios are referred to as medium entropy alloys (MEA). These alloys have attracted the interest of many researchers due to the superior mechanical properties it offers over the traditional alloys. The design approach of MEA often results to simple solid solution with either body centered cubic; face centered cubic structures or both. As the consideration for introducing the alloys into several engineering application increases, there have been efforts to study the corrosion behaviour of these alloys. Previous reports have shown that some of these alloys are more susceptible to corrosion when compared with traditional alloys due to lack of protective passive film. In this research, we have developed AlFeTiV medium entropy alloys containing two elements (Ti and Al) that readily passivate when exposed to corrosive solutions. The alloys were produced in vacuum arc furnace purged with high purity argon. Open circuit potential and potentiodynamic polarisation tests were used to evaluate the corrosion behaviour of the as-cast AlFeTiV alloy in 3.5 wt% NaCl and 1 M H2SO4. The corrosion performance of the alloy was compared with Ti- 6Al-4V alloy tested under similar conditions. The results show that unlike in Ti-6Al-4V alloy, the open circuit potential of the AlFeTiV alloy move towards the negative values in both 3.5 wt% NaCl and 1 M H2SO4 solutions indicating that self-activation occurred rapidly on immersion. Anodic polarisation of the alloys showed that AlFeTiV alloy exhibited a narrow range of passivity in both solutions. In addition, the alloys exhibited lower Ecorr and higher Icorr when compared with traditional Ti-6Al-4V alloy. The traditional Ti-6Al-4V alloy showed superior corrosion resistant to the AlFeTiV alloy in both 3.5 wt.% NaCl and 1 M H2SO4 solutions.
