- Description: This thesis represents an experimental and intellectual journey of more than three years. The String Vibrator Experiment (SVE) is an experimental payload on the SumbandilaSat, satellite. The experiment was initially designed to compare low-earthorbitstretched string nonlinear dynamics with those found terrestrially, with particular emphasis on the effects of micro-gravity and near vacuum. Due to the damage of some internal components of the SVE, the terrestrial experiment had to be characterized by finding both transverse fundamental natural frequencies and the longitudinal system fundamental natural frequency. Forced and free vibration tests were performed on the SVE, with comparable results. The percentage frequency difference between measurement results obtained for the said natural frequencies was found to be acceptable. An analytical model for the string longitudinal system was developed using Energy Methods, assuming linear coupling of the stretched string and the flexible support. Bessel Functions were used to find the natural frequency of the flexible support, which is made of a thin-circular plate loaded centrally by the stretched string and fixed on its outer boundary. The natural frequency thus predicted, corresponds closely with that measured by Laser Doppler Vibrometry. It was found that the longitudinal system behaves in an uncoupled, manner. In this study use was made of piezo bi-morph sensors as vibration measuring devices, with promising results. A method called the peak amplitude discrimination method is introduced to find the respective resonant frequencies; this method is an adaptation of the sweptsine frequency method Nonlinear behavior of the SVE was found to exist exhibiting Sub-harmonics, Super-harmonics, Combination harmonics and Internal Resonances. It is hoped that the experimental methods used in this study would aid in the measurement and analysis of longitudinal vibrations found in flexible cables, rods and rigid bars. , Thesis (PhD) -- Faculty of Science and Agriculture, 2011

- Description: The nationwide strike by 70 000 construction workers between 8 and 15 July 2009 was unprecedented and significant in several respects. This was the first national strike on 2010 World Cup sites by South African construction workers and was therefore an historic event. A second key feature of the strike was the unity displayed by workers and trade unions within a sector organised by several trade unions. Engineering and building workers came out on strike, with the Building Construction & Allied Workers Union (BCAWU) and the National Union of Mineworkers (NUM) standing together as their representative organisations. A third feature of the strike was the widespread sympathy for it by the South African public and media. This was despite it potentially setting back progress with World Cup projects. Fourthly, the pressure placed upon the trade unions' negotiating team by the Ministry of Labour and the FIFA Local Organising Committee (LOC) proved lethal in undermining their, assisting in causing them to dilute their trade union demands and demobilising the national strike.

- Description: The study was set out to examine the implementation of Performance Management System at Lilongwe Technical College in Malawi. The reason for pursuing the study is to contribute to the improvement and strengthening of the implementation of the Performance Management System which is already in place at the college. The objectives of the study were to assess the attitudes and perceptions of employers regarding the implementation of the PMS at Lilongwe Technical College; to establish the challenges inhibiting successful implementation; and to provide possible mechanisms to improve the situation. The research methodology used was a qualitative research approach, based on in-depth interviews, observation and secondary resources that is reviewing the necessary information available in connection with the topic. After analyzing the relevant information, it became apparent that the performance management system is lacking understanding of the policy, procedures and processes, senior management does not seem to be committed to the successful implementation of the PMS and also lack of motivation and advocacy from top management. The researcher has given recommendations in chapter 5 so that it would contribute to more efficient and effective implementation of the Performance Management System at Lilongwe Technical College. , Thesis (MA) -- Faculty of Management and Commerce, 2011

- Description: HIV counselling and testing has long been identified and used as an important entry point around the world in trying to minimise the impact of HIV, particularly on vulnerable populations. South Africa is one of the countries in the world most affected by HIV, and despite concerted governmental efforts to try to contain the disease since the 1990‟s; it remains a threat to the South African population today. Teenagers are a particularly vulnerable group, as they have been found to often engage in behaviours without apparent regard for the consequences of such actions. With the government’s recent upscale of HIV counselling and testing, through its largest national HCT campaign which includes school learners, this study aimed at establishing the perceptions of high school learners through a KABP survey. The study found that while learners may have the necessary knowledge of HIV/ADS, this did not necessarily determine their sexual behaviour or attitudes. Variations were also found in terms of their developmental needs, with possible implications for testing campaigns. Finally, a lack of trust that confidentiality would be maintained may seriously limit uptake of such a service at schools. , Thesis (MA) -- Faculty Social Sciences and Humanities, 2011

- Description: This study analyses the determinants of demand for public transport in South Africa, using quarterly data covering the period from 1990-2009. The study initially provides an overview of the South African public transport system and population trends. Based on the review of the theoretical and empirical literature on transport, the study specifies a model of public transport demand in South Africa. Tests for stationarity and unit roots in the series (both informal and formal tests), and co-integration test have been performed. The co-integration test is done using the Johansen (1990, 1995) methodology. A vector error correction model is run to provide robust determinant variables on public transport. The results revealed that in the short run, the demand for public transport depends positively and significantly on GDP per capita growth and negatively on prices for public transport and fuel prices. However, over the long run, the demand for public transport depends negatively on GDP per capita growth as expected, but positively on the other variables including the growth in employment levels. To check for robustness of the VECM results the diagnostic tests were performed. The AR Roots Graph reports the inverse roots of the characteristics AR polynomial. The graph showed that all roots lie inside the unit circle which is an indication that VAR is stable. Some of the results found in this the study, such as the short run and long run impact of income growth on public demand, are supported by findings from other studies. , Thesis (MCom) -- Faculty of Management and Commerce, 2011
