- Description: The South African Automotive industry has been one that has enjoyed the subsidies schemes like the Motor Industry Development Program (MIDP), and in the near future the Automotive Production Development Program (APDP). There are however different schools of thought when it comes to subsidies for an industry. One is that there should be no incentives when others are for the schemes, which one is best for the growing economy of a young democratic and highly unemployed nation? Looking at the next planned incentive scheme to be introduced to replace the MIDP, the APDP is it better than the MIDP? How are these schemes going to benefit the country in the future and will they exist for as long as we have the Auto industry in South Africa? The objective is to prompt those in political power and positions capable of influencing infrastructure changes to think long term when making decisions today that will affect future generations. Future generations should be able to benefit from future technologies of the day and not be hindered by the lack of improved and capable infrastructure.

- Description: The research work conducted and presented forward in this document is the evaluation of real time values obtained using three recording devices at two independent locations and implementing them as recorder devices in Eskom’s power system. The research work conducted was presented at an IEEE International Conference (ICIT2013) and Appendix A shows the accepted paper presented. A derived model within a simulation software package known as DIgSILENT PowerFactory is created and Electromagnetic Transient (EMT) studies are performed and then compared to the real time values obtained using the OMICRON CMC 356’s. Transformers are normally energised via a circuit breaker which is controlled by an auxiliary closing contact. By applying system voltage at a random instant in time on the transformer windings may result in a large transient magnetizing inrush current which causes high orders of 2nd harmonic currents to flow under no load conditions. A philosophy known to mitigate these currents is to energise the transformer by controlling each individual phase 120 degrees apart with the first pole closing at the peak on the voltage waveform. Transients produced due to 500MVA transformers been introduced into the power system at a certain space in time can cause nuisance tripping’s at the particular location where the respective transformer is energised. OMICRON EnerLyzer is the software tool used for the Comtrade recordings at both locations. Four independent case studies are generated within EnerLyzer software and the relevant Comtrade files are extracted for the four independent case studies relative to Transformer1 and Transformer2 switching’s. TOP software, which is a mathematical tool used to analyse Comtrade files, is then used to analyse and investigate the four case studies. Results from DIgSILENT PowerFactory are then generated according to the derived model. The results extracted depict three scenarios, indicating a power system that is weak, strong and specifically a power system that correlates to the actual tripping of a Static VAr Compensator (SVC). The results are all formulated and then evaluated in order to produce a conclusion and bring forward recommendations to Eskom in order to effectively ensure the Dedisa/Grassridge power system is reliable once again.

- Description: Human resource management, or people management, is concerned with the philosophies, policies, programmes, practices and decisions that affect the people who work for an organisation. The various people management functions are aimed at helping the organisation achieve its strategic goals and as such are an integral part of the management process. People management consists of several aspects and sub-divisions of which pro-active conflict handling and management is one and which is also the subject of this study. The objective of this study was to assess causes of conflict and interventions and styles of conflict management in the workplace. Workplace politics, change management, diversity, cultures and religious views are but a few major sources for the emergence of conflict. We are currently in the era of fast change or more aptly put “hyperchange” and conflict is inevitable and management styles can also create and/or escalate conflict situations including, the composition of diversity in the workplace. This adds to the new challenges of management. Organisations in this decade need to acknowledge that their management styles of days gone by are not relevant anymore and one must understand to recognise conflict and resolve it in an appropriate manner. This study assessed the major causes of conflict in the workplace and whether the managerial style of managers and management interventions impacts on the overall conflict situations experienced by staff members in organisations in Cape Town and Windhoek. It also gave an indication if interventions and conflict management training/programmes are in place or used, if at all. Sometimes conflict is resolved successfully or unsuccessfully and what impact it has on the managers, his/her staff and colleagues and the organisation as a whole. This can have a detriment impact on the business and the culture within the organisation and which could result in or give rise to high labour turnover, underlying unhappy staff and disempowerment of managers and staff and poor production and service levels.

- Description: Society’s reliance on Information Technology (IT) has increased tremendously in the last few decades. Unfortunately, the growth of the IT sector has occurred at the expense of the environment. The adverse environmental impact of IT operations is partly due to the production and disposal of IT equipment, which can result in harmful pollution and toxic materials being released into the environment. Furthermore, IT equipment consumes large amounts of electricity, and this results in significant amounts of carbon dioxide (CO2) being released into the atmosphere. Since CO2 is classified as a greenhouse gas, it contributes to the phenomenon of climate change. Organisations are socially and ethically required to minimise the environmental impact of their IT operations. However, in addition to fulfilling their responsibility towards environmental sustainability, organisations can gain a competitive advantage through adopting green IT practices. In order to reap the benefits of green IT and to fulfil their social and ethical responsibilities, organisations need to formulate and implement a comprehensive green IT strategy. When formulating strategic decisions, the use of a clear decision process enhances the effectiveness of such decisions. As a result, top IT management require a model or framework which could guide their thinking and allow for a clear decision process when formulating green IT strategy. However, after an extensive search of the literature had been conducted, a research gap was identified for the definition of a model which deals specifically with the formulation and execution of green IT strategy. As a result, this treatise sets out to answer the question of what organisations should consider when formulating and implementing green IT strategy. To answer the research question, the treatise defines a model for green IT strategy. The model was defined by conducting a content analysis of the literature on green IT. The content-analysis ABSTRACT iii research technique was utilised to identify the underlying concepts within the literature related to green IT strategy formulation and execution. The resulting model indicates that green IT strategy formulation requires holistic thinking, since several forces affect green IT strategy. As a result, these forces should be considered when a green IT strategy is to be formulated. However, even if a strategy is formulated by considering all the forces at play, it is of little use if it is not implemented effectively. The model indicates that green IT strategy should be implemented though a series of practices. These practices are not limited to IT practices alone, but include, in addition, several business practices. This indicates that green IT adoption extends far beyond the mere implementation of green technology.

- Description: Retirement has different meanings for different people. Retirement represents a significant transitional period in the life cycle of an individual. The aim of the study was to explore and describe the experiences and coping resources of retirees. The researcher applied an exploratory, descriptive research design employing the mixed methods of quantitative and qualitative research to gain an in-depth understanding of the phenomenon. A non-probability purposive sampling method was used to identify participants who retired from a specific vehicle manufacturing company in Port Elizabeth. Semi-structured interviewing techniques and a questionnaire called the Coping Resources Inventory were used for data collection. The rationale for using a mixed method approach was to increase the validity of the research findings. Descriptive statistics and the framework provided by Tesch (in Creswell, 2003) were used in data analysis of quantitative and qualitative data respectively. The results of the Coping Resources Inventory indicated that the participants perceived themselves as having an average level of coping resources. The results from the semi-structured interviews reflected that participants’ retirement experiences are mainly influenced by the following three factors: (a) economic resources, (b) social relationships and (c) personal resources. Recommendations were made for future research and intervention regarding retirement planning. The researcher included suggestions for the implementation of a retirement preparation programme. Lastly the limitations and the value of the study were outlined.
