Over the past 30 years South Africa has lost valuable human capital due to high volumes of emigration. South Africa has also seen numerous changes in its political, economic and social structure specifically in these decades, but little investigation has been done into the possibility of an association between political, economic and social, as well as personal factors, and the decision to leave South Africa. This study refers to Lee’s Migration Model (1966) that was used as a broad theory for migration. The model involves four sets of factors: factors associated with the area of origin, factors associated with the area of destination, intervening obstacles and personal factors. Maslow’s Hierarchy of Needs Theory also explains the personal motivational theory for migration. Lee’s Model of Migration is used to investigate which political, economic, social and personal factors in the area of origin (South Africa) pushed South African emigrants to leave the country. It also investigates which political, economic, social and personal factors in the area of destination (Australia and New Zealand) pulled South African emigrants toward these countries. This study involved mixed-methods research (Creswell, 2009), thus the data collection methods were both qualitative and quantitative. The study followed a sequential exploratory strategy in two stages with the qualitative data collection occurring first, followed by a quantitative study – ‘QUALquan’ study. The data are mixed between analysis of the qualitative data and the quantitative data collection (Creswell, 2009:211). The qualitative data collection instruments used in the first stage of the study in 2009, were face-to-face interviews consisting of one focus group and six personal interviews in New Zealand, as well as twelve personal interviews in Australia. In the second stage of the study in 2015, namely the quantitative research, respondents were selected by contacting 17 closed (secured) Facebook groups that were formed for South Africans living either in Australia or New Zealand. There is no alternative sampling frame available since emigrants do not need to declare themselves as migrants on a work visa, furthermore, official documentation is not accessible to the public. A quantitative data collection instrument was administered with an online questionnaire. In the Australian Facebook groups, 137 respondents completed the questionnaire, and in New Zealand Facebook groups, 118 respondents, which adds up to a total of 255 respondents who completed the questionnaire. The results concluded that South Africa’s governance framework, its infrastructure and legislation acted as political push factors motivating South Africans to emigrate, while an uncertain economy contributed as an economic push factor. Socially, a perception of a limited future and a narcissistic society is what pushed South Africans to emigrate. Personal push factors that drove the emigration decision included, unmet physical, safety, belonging and esteem needs. The political factors that pulled South African emigrants to Australia and New Zealand involved effective government services and governmental aid. Economic pull factors included economic certainty and a lower cost of living. Social pull factors proved to be familiar circumstances and a better future. Personal pull factors were safety, belonging and self-actualisation needs. This mixed-method approach focussed on the gap to a followup study that was identified in previous individual qualitative and quantitative studies. These results may assist the South African government to take measures that ensures the retention of highly skilled citizens. / Business Management / M. Com. (Business Management)

В существующей ситуации высокой непредсказуемости и динамичности рыночного окружения эффективная организация производственного и сбытового процесса становится ключевым фактором успешного функционирования и поддержания долгосрочной конкурентоспособности угольных предприятий на внутреннем и международном рынках. Основой повышения эффективности деятельности угольных компаний может стать применение современного экономико-математического инструментария оптимизации планирования производственной и сбытовой деятельности. Основной целью исследования является совершенствование методического инструментария планирования производственно-сбытовой деятельности угольных предприятий для повышения ее эффективности. В работе представлены результаты исследования особенностей производственно-сбытовой деятельности российских угольных предприятий в современных рыночных условиях: выявлены внешние факторы и внутренние ограничения, оказывающие существенное влияние на эффективность их деятельности, проанализированы существующие методы планирования производственно-сбытовой деятельности, а также обозначены возможные пути повышения эффективности. В магистерской диссертации разработан методический поход к оптимизации планирования производственно-сбытовой деятельности угольных предприятий с применением экономико-математических методов и методов оптимизации плановых решений. / In the current situation of high unpredictability and dynamism of the market environment, the effective organization of the production and marketing process becomes a key factor in the successful functioning and maintenance of long-term competitiveness of coal companies in the domestic and international markets. The basis for improving the efficiency of coal companies can be the use of modern economic and mathematical tools for optimizing the planning of production and marketing activities. The main purpose of the study is to improve the methodical tools for planning the production and marketing activities of coal companies in order to increase its efficiency. The paper presents the results of a study of the features of the production and marketing activities of Russian coal companies in modern market conditions: external factors and internal constraints that have a significant impact on the efficiency of their activities are identified, existing methods of planning production and marketing activities are analyzed, and possible ways to improve efficiency are identified. In the master's thesis, a methodical approach to optimizing the planning of production and marketing activities of coal companies was developed using economic and mathematical methods and methods for optimizing planned decisions.

This diploma thesis deals with behavioural problems of pupils in a school setting, particularly with aggression and bullying, as well as the possibility of their prevention. It consists of a theoretical part, a practical part, and appendices. The theoretical part treats behavioural problems in pupils, presenting the separate disorders in all their possible forms, accounting for both internal and external factors triggering them, explaining their causes and the conditions under which they occur, and, finally, surveys the possibility of their prevention and treatment. The practical part uses a questionnaire designed by the author of the thesis and discussions conducted in schools to identify the most common types of behavioural disorders. The results of the research are presented in charts and graphs and are complemented by data obtained in the discussions. This part is concluded with a thorough analysis of the data. The appendices contain real-life examples of behavioural problems encountered by teachers, the minimum prevention programme implemented by the basic school in Jistebnice and its evaluation for the school year of 2008/2009, the crisis management scheme of the same school, and additional materials relating to the topic.
