Thesis (M.A. (International Relations))--University of the Witwatersrand, Faculty of Humanities, 2016. / With sport becoming a worldwide phenomenon through the international nature of matches and events, International Relations (IR) academic writers have had to take note. States and cities are increasingly using major sporting events and activities to re-image themselves, promote development and regeneration. Therefore, this research report will highlight numerous connections sport and IR possess through examining the widely proclaimed developmental impacts of hosting a mega sporting event (MSE) such as the FIFA World Cup. The professionalization and resultant commodification of sporting events seen through the transnational actor FIFA and World Cups in South Africa 2010 and Brazil 2014 will be used as case studies. These chosen cases will illustrate that in reality the FIFA World Cup is not as beneficial for host nations from the emerging or developing world as claimed. The research will be theoretically based on the perspective of neoliberalism in relation to the IR concept of Globalization.

Esta tese apresenta pela primeira vez a obtenção, a partir de alcoóis, de nanotubos de carbono do tipo cup-stacked nitrogenados sendo esses nanotubos hidrofílicos e semicondutores. Os compósitos híbridos de fibra de carbono/nanotubos de carbono possuem geometria tridimensional nanoestruturada e foram preparados em reator de deposição química de vapor de leito fixo. Neste processo nanotubos de carbono do tipo cup-stacked nitrogenados, de paredes múltiplas organizadas ou helicoidais são crescidos diretamente sobre as fibras de carbono com diferentes graus de grafitização. Os compósitos obtidos foram analisados principalmente por microscopia eletrônica de varredura e de transmissão de alta resolução que mostrou que o grau de grafitização do substrato de carbono tem influência sobre o crescimento. A densidade de NTC diminui com a redução da grafitização das fibras de carbono, o que produz um material com porosidade não observada quando as fibras são bem grafitizadas. O material compósito foi estudado como elemento filtrante, eletrodos de baterias de íons de lítio, emissor de elétrons e como reforço em compósitos de silicone. A constatação da eficiência na filtragem seletiva de uma série de compostos orgânicos voláteis presentes na fumaça do cigarro bem como a preparação de eletrodos de baterias de íons de lítio sem o uso de folhas metálicas de alumínio ou cobre resultaram no deposito de dois pedidos de patente. / This thesis presents for the first time nitrogen-cup-stacked carbon nanotubes with hydrophilic and semiconducting properties synthesized by alcohol precursor. The hybrid carbon fiber/carbon nanotubes composite have three-dimensional geometry and nanostructure. The material was prepared via fixed-bed chemical vapor deposition reactor. In this process nitrogen-cup-stacked, multi-walled or helical carbon nanotubes were synthesized directly onto carbon fibers with different graphitization grade. The composites were analyzed by high resolution scanning and transmission electron microscopy. This characterization showed that the fiber graphitization has influence on the growth. Carbon nanotube density decreases producing a porous composite that was not observed in well-graphitized fibers. The hybrid composite material was studied as a filter, lithium ion battery electrode, electron field emission and as silicone reinforcement. The efficiency to filter several volatile organic compounds present in the mainstream smoke and the development of lithium-ion battery electrodes, aluminum and copper foils free resulted in two patent applications deposit.

Em virtude da demanda cada vez maior por materiais de alta qualidade, o avanço das tecnologias aplicadas na produção de aço vem acompanhado pelo avanço na fabricação de revestimentos refratários de alto desempenho e que atendam às solicitações de processo sem interferir nas propriedades finais do material produzido. Os refratários de magnésia-carbono são atualmente os materiais mais utilizados em equipamentos siderúrgicos tanto de transporte como de refino do aço, sendo de extrema importância o conhecimento da qualidade das matérias primas utilizadas na confecção destes materiais. O presente trabalho tem como objetivo estudar como ocorre a corrosão da magnésia (eletrofundida e sinterizada) por escória de aciaria LD em ensaios de corrosão estáticos (cup-test) porém com algumas modificações ao ensaio convencional, chamado assim de cup-test modificado. A magnésia foi caracterizada por ensaios de caracterização química (fluorescência de raios X), mineralógica (difratometria de raios X) e microestrutural (microscopia eletrônica de varredura com análise da energia dispersiva de raios X). A análise química mostrou que as principais impurezas do material eram de cálcia (CaO) e sílica (SiO2) e a análise microestrutural mostrou que estas impurezas se concentram nos contornos de grão dos agregados eletrofundidos e dispersos por todo o material nos sinterizados, sendo encontrado apenas periclásio como fase mineralógica. Os maiores tamanhos médios de grãos foram encontrados na amostra ME3 e os menores na ME1. A escória utilizada é proveniente do conversor (BOF), com alta concentração de FeO. As análises após os ensaios de cup-test modificado mostraram que o ataque aos agregados se deu principalmente pela infiltração de fases contendo ferro pelos contornos de grão, arrastando-os para o banho e dissolvendo o MgO na escória. Dentre os eletrofundidos, podemos estimar a ordem de desempenho da seguinte maneira: ME3>ME2>ME1. Considerando os sinterizados, a ordem de desempenho é tal que: MS3>MS1>MS2. / High quality materials are increasingly desired by consumers, and advances in technologies of steelmaking processes are closely linked to manufacturing suitable high performance refractories which do not interfere in the final properties of materials produced. Magnesia-carbon refractories are widely used in several steelmaking plants, both for transportation and refining processes which makes the knowledge of the quality of raw materials is essential for manufacturing high quality refractories. In this work, the approach is the study of how the corrosion behavior of magnesia aggregates (sinterized and electrofused) by LD steelmaking slag occurs using a modified crucible testing. The magnesia aggregates were characterized by X-ray fluorescence (XRF), X-ray diffraction (XRD) and scanning electron microscopy (SEM) with energy dispersive X-ray spectroscopy (EDS). The XRF analysis shows that the main impurities of magnesia grains is CaO and SiO2 and the SEM analysis showed their impurities are concentrate on grain boundary in electrofused magnesia, while it is found throughout the sinterized magnesia aggregates. The major phase found both magnesia aggregates is periclase. The largest grain sizes were found in ME3 samples, while the smaller sizes in ME1. The slag used comes from converter (BOF) and has high concentration of FeO. The corrosion tests showed that the attack on magnesia aggregates occurred, mainly by the infiltrating of iron compounds in the grain boundary, dragging the grains to the bath and dissolving them into slag. Among the electrofused, the performance could be estimated in ME3>ME2>ME1. The performance for sinterized would be as follows MS3>MS1>MS2.

Thesis (MTech (Tourism))--Cape Peninsula University of Technology, 2015. / Local business concerns and perceptions are generally neglected in relation to mega-event research, as most studies have, so far, focused on the broader economic impacts, as well as on the social impacts, and, more recently, on the environmental impacts of mega-events. South Africa being afforded the opportunity to host the 2010 FIFA World Cup™ created much excitement for all, and especially so for the business market. This is because the market in question is at the forefront of providing goods and services to the much anticipated increased number of tourists, whether such goods and services consist of the provision of accommodation, food and beverage, or entertainment, as well as ancillary products and services. The focus of the study was on gaining an understanding of the awareness and the impacts of the 2010 FIFA World Cup™ on businesses, especially those situated within close proximity of the Cape Town Stadium. The study was conducted three months before, and three months after, the event. The investigation explores the level of perceptions, attitudes, and experiences of the businesses in relation to the 2010 FIFA World Cup™, while simultaneously highlighting their experiences with the event. The primary objective of this approach was to ascertain whether there were any changes between the initial perceptions, and the experiences, among businesses in relation to the event. The five objectives guiding the study involved investigating: (1) business managers’ and owners’ perceptions and experiences of the event; (2) the impacts of the World Cup on businesses; (3) the level of business support for the event; (4) the impacts of leveraging initiatives on businesses; and (5) recommendations aimed at maximising the opportunities granted by future mega-events for businesses. During the pre- and post-event study, a total of 145 surveys were administered to the business owners and managers of SMMEs, using the stratified random sampling method, of which, 72 responded during the pre-event study and 104 during the post-event study.

M.Com. (Financial Management) / This study was an investigation into the impact of hosting the FIFA World Cup soccer tournament on the stock market of the host country. The investigation looked at whether stock markets react efficiently or show a positive reaction to the hosting of the FIFA World Cup. Hosting the FIFA World Cup was assessed at two event dates: the announcement date where the host country’s winning bid is announced and the when the tournament starts. An event study research methodology was used to investigate the impact of hosting the FIFA World Cup on the stock exchange of the host country, by examining the movement of CARs across the two event windows. It was found that stock markets react differently to the announcement of the tournament and event start dates. The results of this study show that the stock market does not always regard the hosting of the FIFA World Cup as positive news, therefore resulting in either a positive or negative stock market reaction. Markets do however appear to be efficient and incorporated all information in stock prices. The test statistics showed a number of statistically insignificant results; hence the presented results do not support the hypotheses that the FIFA World Cup has a significant impact on the host country stock market during the announcement and hosting stages.

Thesis (MTech (Tourism and Hospitality Management))--Cape Peninsula University of Technology, 2018. / Sport mega-events are a powerful tool for branding nations. There has been a significant shift in countries that bid for and win the rights to host sport mega-events. Historically, Western countries used to be leaders in winning rights to host such events; however a new emerging trend has seen developing countries winning the rights ahead of developed ones, for example, South Africa, Brazil and Russia winning the rights to host the FIFA World CupTM. South Africa faced a serious branding challenge leading up to the 2010 FIFA World CupTM. Therefore, one of the primary objectives of hosting this tournament was to change international tourists’ perceptions of South Africa. There has been limited research on the brand legacies of the 2010 FIFA World CupTM, hence this research examined the brand image legacies of the tournament in the long run. It is believed that the football fans who attended the 2016 UEFA European Championship either visited South Africa during the 2010 FIFA World CupTM or watched the tournament on television (TV) at home, therefore they have certain perceptions of South Africa as a sport tourism destination. A quantitative methodology was employed to survey football tourists at fan parks and stadium precincts in five metropolitan cities in France during the 2016 UEFA European Championship, using a spatially based systematic sampling technique. In total 391 football tourist questionnaires were completed. The key findings reveal that prior to the 2010 FIFA World CupTM, football tourists’ perceptions of South Africa as a sport tourism destination were generally positive; however they indicated that they were very concerned about safety and security, as well as segregation issues, prior to the tournament. It can be argued that the tournament had a significant impact on reinforcing the positive perceptions of the destination as well as reducing the negative perceptions of the destination. The findings reveal statistically significant differences in most aspects between tourists’ perceptions prior to, and six years after, the 2010 FIFA World CupTM. Tourists’ perceptions on most aspects changed positively six years after the event, including those that were major concerns prior to the tournament. The findings also show that there has been very little repeat visitation to South Africa since South Africa hosted the 2010 FIFA Word CupTM. However, an overwhelming majority of respondents indicated that they were willing to travel to South Africa should it host another sport mega-event in the near future. The key findings of this study have a wider applicability to sport mega-events legacy research and body of knowledge. These key findings can assist destination marketers in managing the destination image and foster a greater understanding of brand image legacies of past mega-events in order to inform the bidding and hosting of future sport mega-events.

Entre junho de 2013 e julho de 2014, esse direito foi exercido por milhões de brasileiros que foram às ruas protestar contra a precariedade da saúde e educação pública, a corrupção, o aumento da tarifa de ônibus e também contra os gastos excessivos para a realização da Copa do Mundo. As manifestações sociais aconteceram na mesma época em que dois megaeventos esportivos eram realizados no país: a Copa das Confederações, em 2013, e a Copa do Mundo, em 2014. O objetivo desta pesquisa é verificar se dois veículos de comunicação impressos, Folha de S. Paulo e O Globo, que noticiaram as manifestações sociais, trataram-nas como um exercício pleno do direito à liberdade de expressão, ou criminalizaram o movimento. Para cumprir os objetivos, será utilizada a metodologia da análise de conteúdo. A hipótese é de que os jornais abordaram o assunto de maneira superficial e negativa. A partir das análises quantitativas e qualitativas realizadas com base na metodologia escolhida, tornou-se possível a confirmação de tal hipótese. / The right to freedom of expression is guaranteed by the Brazilian Constitution of 1988, and can be practiced by many different ways. Between june of 2013 and july of 2014, this right was practiced by millions of Brazilians, that went to the street to protest against the precariousness of public health and education, corruption, the increase in the bus pass and also against excessive expenses for the realization of the World Cup. The social manifestations happened in the same time that two sportive mega events were realized in the country: The Confederations Cup, in 2013, and The World Cup, in 2014. The object of this research is to verify if two newspapers, Folha de S. Paulo and O Globo, that noticed the social manifestations, treated them as an exercise of the right to freedom of expression, or criminalized the protest. To meet the goals, it will be used the methodology of content analysis. The hypothesis is that the newspapers dealt with the issue in a superficial and negative way. By the quantitative and qualitative analysis based on the chosen method, it became possible to confirm this.

Thesis (DTech (Tourism and Hospitality Management))--Cape Peninsula University of Technology, 2016. / The hosting of mega-events such as the 2010 FIFA World CupTM create expectations from the host nation, especially in the host cities. This is largely due to the impacts associated with the hosting of such events. Planning is perceived to be at the centre of successful hosting of such events. Planning also assists in making sure that benefits from such events are maximised and costs minimised. Events like the 2010 FIFA World CupTM do not only require high level planning but also a multi-stakeholder approach. With South Africa and the continent hosting the FIFA World CupTM for the first time since its inception, expectations were rising from both host and non-host areas. The study investigates a multi-stakeholder approach to planning on the 2010 FIFA World CupTM initiatives conducted by a non-host area - Cape Winelands District Municipality (CWDM), Western Cape, South Africa. The location of the CWDM is less than 45 minutes from the host city (Cape Town). By virtue of its close proximity, the CWDM positioned itself to leverage from the event as a result of possible spill-over effects. The study was driven mainly by five objectives. These include the identification of 2010 FIFA World CupTM planning initiatives, assessment of planning initiatives in relation to beneficiation of local municipalities, gaining an understanding of ways in which various stakeholders are involved in the planning initiatives, ascertaining ways in which various stakeholders perceive the benefits/spill-over effects and examining the alignment, integration and co-ordination of the 2010 FIFA World CupTM planned initiatives in the CWDM. In pursuing these objectives, both qualitative and quantitative research methods were used in the collection of data. Respondents included residents (n=1 250), established businesses (n=108) and CWDM officials (n=5), using stratified random sampling, convenient sampling and purposive sampling, respectively. A total of 1 363 questionnaires were administered among the respondents of the study.

Streamflow and suspended sediment daily measurements have been carried out by February to December 2013 and climatic data were obtained form a weather station located inside the basin. Terrain data such as Digital Elevation Model (DEM), soil types, and land use were on the SWAT autocalibration too as well as on SWAT-CUP software, which is a specific too for automatic calibration. Initially, the simulation run in SWAT overestimated values of runoff peak and underestimated minimum discharges. However, the peaks were minimized and minimum discharges were adjusted to the observed flows after sensitivity analysis. By using different optimization schemes (GLUE, PARASOL and SUFI-2) in SWAT-CUP, an automatic calibration analysis has been done, which presented a better fit to the observed values (start with streamflow, than move to sediment). Statistical analysis using the coefficient of Nash-Sutcliff efficiency (COE) resulted in 0.80 and 0.88 for runoff and suspended sediment, respectively, which are considered good fits between simulated and observed values. The CN parameter, which is related to soil type, land use, and infiltration, showed the highest sensitivity in the calibration. After that, the alpha factor of base flow was another which showed higher sensitivity. The higher value obtained for the Manning roughness coefficient allows runoff to be damped. With regard to sediment calibration, parameters of sediment from landscape (USLE_P and USLE_C) as well as parameters of sediment from channel (SPCON and SPEXP) have been used in the calibration, once that they have shown higher sensibility. / O objetivo desta pesquisa é fazer a análise da calibração do modelo SWAT em termos de fluxo e sedimentos na bacia do Córrego Samambaia, uma microbacia (32,78km2), localizada em Goiânia, Brasil. Medições diárias de vazões e sedimentos foram realizadas em Fevereiro a Dezembro de 2013, e os dados climáticos foram obtidos a partir de uma estação meteorológica localizada no interior da bacia. Dados do terreno, tais como Elevação Digital do Terreno (MDT), tipos de solos e usos da terra foram obtidos do Sistema de Informação e Estatística de Goiás (SIEG). Análises foram realizadas na ferramenta autocalibração do SWAT, bem como no software SWAT-CUP, que é uma ferramenta específica para a calibração automática. Inicialmente, a execução da simulação no SWAT superestimou os valores de pico do escoamento e subestimou as vazões mínimas. No entanto, os picos foram minimizados e as vazões mínimas foram ajustadas para os fluxos observados após análise de sensibilidade. Ao utilizar diferentes esquemas de otimização (GLUE, ParaSol e Sufi-2) no SWAT-CUP, uma análise de calibração automática foi feito, que apresentou um melhor ajuste aos valores observados (começando pela vazão a qual altera o sedimento). A análise estatística do coeficiente de eficiência de Nach-Sutcliffe (COE) resultou em 0,80 e 0,88 para o escoamento superficial e sedimentos em suspensão, respectivamente, que são considerados bons ajustes entre os valores simulados e observados. O parâmetro CN, que está relacionado com o tipo de solo, uso da terra e infiltração, apresentou maior sensibilidade na calibração. Depois disso, o fator alfa de fluxo de base foi outra que mostrou maior sensibilidade. Quanto maior for o valor obtido para o coeficiente de rugosidade de Manning permite que o escoamento seja amortecido. No que diz respeito a calibração dos sedimentos, os parâmetros de sedimentos de paisagem (USLE_P e USLE_C), bem como os parâmetros de sedimentos a partir do canal (SPCON e SPEXP) tem sido utilizados na calibração, uma vez que eles mostraram maior sensibilidade.
