The airline industry has grown rapidly over the past few decades, recording a ten-fold rise in passenger numbers and a fourteen-fold increase in cargo volumes. This growth has created overwhelming value to airline passengers, employees, suppliers and the broader economy. Unfortunately, this industry has been affected by terrorism attacks, wars, revolutions, pandemic fears, earthquakes, volcanoes, failing economies and skyrocketing fuel prices all of which have negatively impacted on profitability and resulted in intense competition. Consequently, airlines have spent the last decade in survival mode having to adapt to harsh changes. Air Zimbabwe, a state-run organisation which operates in this highly regulated and turbulent industry, is faced with numerous micro and macro environmental challenges and has been purposively selected for this study. According to company statistics, the airline’s annual passenger uplifts have declined from a peak of over 1 million in the 1990s to less than 200 000 in 2011, with revenue generation declining in correlation. Whilst Air Zimbabwe has experienced depressed demand for its services, competitor airlines are recording brisk business. The aim of this study was to investigate how a struggling organisation, which operates in a turbulent environment, can improve its competitiveness and profitability by better understanding the impact of industry role players and adapting organisational strategies to industry variations. This study examined, from the point of view of the industry players themselves, the extent to which customers, suppliers, competitors, regulatory authorities, substitute products and new entrants have impacted on the competitiveness and profitability of the airline. Major findings reveal that an organisation cannot operate in isolation and be competitive or profitable, but constantly needs to analyse the industry environment in which it operates in and to amicably interact with other industry role players. The research outlines the need for competition in certain areas and cooperation in others. / Business Management / M. Com. (Business Management)

Thesis (MBA)--Stellenbosch University, 2011. / Gaia Power is a South African start-up in the renewable energy industry. Among other products, they developed a wave energy converter, which is a device used to extract energy from ocean waves. This research deals with the economic feasibility study of the wave energy converter. Wave energy is a young field of research, especially in the South African context. Therefore sources for multiple angles of the project had to be found, analysed and brought into the Gaia Power context. Understanding the cost drivers of a wave energy plant was the foundation of the research itself. The Gaia Power specific levelised cost of electricity generation was calculated based on actual supplier quotes, reference costs found in the literature as well as assumptions. Still, such a calculation is actually more an estimation due to a high uncertainty level in all cost components. Especially the construction cost as well as the discount rate used have therefore been tested for sensitivity. Gaia Power‟s target production cost was R0.54 kWh, which equalled the Eskom tariff at the time of this research. Taking into account a R0.10/kWh fee payable to Eskom, the target cost sank to R0.44, which is about 25 percent lower than the minimum value for electricity generation cost found in the literature. This target was therefore expected to be and proved to be difficult to reach. The calculated levelised electricity cost was R0.99/kWh, with a possible range of R0.54/kWh to R1.60/kWh observed in the sensitivity analysis. These results show that the Gaia Power wave energy converter in the given specifications was not economically feasible. It was therefore recommended to rethink the specifications in order to reduce construction cost, which proved to be the largest cost driver. Besides the quantitative findings, this research also has a strong qualitative side. During the whole research it became obvious that there was an overall high risk level in the project due to the lack of experience with wave energy in general and in South Africa specifically, as well as the high impact of weather on the construction. Those risks were identified, analysed and recommended mitigation actions were derived.

This study explores the relationship between economic development, social mobility, elites, and regime formation. I argue that the genesis of regime formation, in general, and of democratic regimes, in particular, is determined by the type of economic structure a society possesses, on the one hand, and on the degree the to which demands from disfranchised groups do or do not pose a substantial threat to the interests of elites who occupy the upper strata of the social and economic status hierarchy. Second I demonstrate that the dynamics of transition to wider political participation, as the core element of a democratic system of governance, and the survival of such change are different. In what follows I illustrate that some factors that have been found to dampen the chances for wider participation or have been found to be unrelated to onset of a democratic system of governance have considerable impacts on the durability of the democratic regimes. In a nutshell, the analysis points to the positive effects of mineral wealth and income inequality on the prospects of a democratic survival. Using a cross-national time series data set for all countries for the period between 1960 and 1999 I put the hypotheses to the test. I use binary logit, ordered logit, and ordinary least squares (OLS) to delineate the link between socioeconomic changes and the transition to wider participation. Survival analyses are employed to test for what factors account for the durability of a democratic regime.

M.A. (Social Work) / Assistance with a disability grant has made a number of positive contributions, especially to improving the life of its beneficiaries. In addition to the increasing number of job demands by a multitude of people in the country, there are also thousands of people living with HIV and AIDS who apply, especially those who have no income, for a disability grant to meet their basic needs and promote positive health. Throughout the study, it has been identified that the disability grant not only benefits individual beneficiaries in most instances, but also benefits their families and plays a major role not only in ensuring food security, but is extended in meeting other basic needs of the households. By its nature, the disability grant is not permanent social assistance as beneficiaries only qualify for a period ranging from six to 12 months. The cancellation of the grant also leaves the beneficiaries in a vulnerable condition as on cancellation, some beneficiaries are not in a position to provide for themselves financially. For the purpose of the study, purposive sampling was selected for its convenience in getting information relevant to the study. The study was guided by its goal which was to explore the need for developmental programmes for HIV positive disability grant applicants, with the purpose of improving food security and self-reliance. The objectives of the study included the interrogation of grantees on their desire, or not, to be self-reliant, to solicit their ideas for developmental programmes, to consult with social workers who are experienced in the field of Antiretroviral (ARV) intervention on alternative developmental programmes for disability grant re-applicants, and to make recommendations to social workers regarding appropriate developmental programmes for disability grant re-application. Practically, South Africa has no alternative assistance which will ensure continuous food security once the grant has lapsed. This raises a need for initiatives to address this situation as it was discovered that disability grant beneficiaries feel that they can participate in income-generating activities and thereby take more control of their lives and be economically sufficient. Other factors that were identified included a will to change and self-determination. These factors were therefore identified as better tools to be utilised and invested in to encourage them to do things for themselves, as meeting their basic needs is their individual responsibility, especially in cases where the individual‟s medical condition has improved. These interventions need to consider the socio-economic factors of the grant applicants as services provided to them should not treat other factors in isolation since the focus has been on medical aspects; hence assistance with disability grants is only provided when they cannot provide for themselves due to poor health and poor physical strength.
