O JOGO QUE NUNCA ACABOU: A PERMANÊNCIA DO MARACANAÇO NO IMAGINÁRIO DOS BRASILEIROS E SUAS REATUALIZAÇÕES CONTEMPORÂNEAS / THE GAME THAT NEVER ENDED: PERMANENCY OF MARACANAÇO IN BRAZILIANS IMAGINARY AND CONTEMPORARY UPDATES

Corteze, Késia Costenaro 07 July 2015 (has links)
This study aims to relate two peculiar events that marked the history of Brazil in relation to football: The 1950 and 2014 World Cup. The only two events held in Brazil were characterized by great preparation of the event infrastructure and enormous expectations of the crowd by winning the title, but it was not what happened. The two Brazilian Cups have been characterized by two very significant losses, the Maracanaço and Mineiraço, these were compared by fans and media and regarded as the worst defeats of the Brazilian team. To understand this problematic we carried out a Virtual Ethnography in Twitter platform in order to verify what users were commenting on the particular subject, as well as research in newspaper archives available online to also observe how the media have related these two Brazilian losses Thus, it was possible to understand with Maracanaço (1950) was gaining new meanings and updated with the new Brazilian defeat in 2014, the Mineiraço. / O presente trabalho tem por finalidade relacionar dois eventos peculiares que marcaram a história do Brasil em relação ao futebol: A Copa de 1950 e a de 2014. Os dois únicos eventos sediados no Brasil foram marcados pela grande preparação da infraestrutura do evento e enorme expectativa da torcida pela conquista do título, porém não foi o que aconteceu. As duas Copas do Brasil foram caracterizadas por duas derrotas muito significativas, o Maracanaço e o Mineiraço, essas que foram comparadas pelos torcedores e mídias e tidas como as piores derrotas da seleção brasileira. Para compreender essa problemática realizou-se uma Etnografia Virtual na plataforma Twitter com o objetivo de verificar o que os usuários estavam comentando sobre o determinado assunto, assim como, uma pesquisa nos acervos de jornais disponibilizados da forma online para também observar como as mídias relacionaram essas duas derrotas brasileiras. Assim, foi possível compreender com o Maracanaço (1950) foi ganhando novos significados e reatualizado com a nova derrota brasileira em 2014, o Mineiraço.

VARIABILIDADE ESPACIAL DO SOLO EM UM GRAMADO DE FUTEBOL / SPATIAL VARIABILITY OF SOIL IN A LAWN OF FOOTBALL

Amaral, Andervan 24 January 2014 (has links)
Are incipient the studies on fields sports using tools to precision agriculture (PA). The aim of this study was to evaluate the spatial variability of soil properties in a pitch football, using PA techniques, in order to provide enhancements to the lawn. The study was conducted on a pitch football with dimensions of 100m x 70m belonging to Itapagé Esporte Clube in the city of Frederico Westphalen (RS). The area was divided into a sampling grid of 10 x 7m, totaling 100 sampling points, where samplings were carried out in depth from 0.00 to 0.10 m. The attributes analyzed were : clay content, phosphorus ( P ), potassium ( K ), pH in water and organic matter (OM ). The attributes were analyzed using descriptive statistics, obtaining the position measurements (minimum, average and maximum) of dispersion (standard deviation, coefficient of variation, coefficient of skewness and kurtosis coefficient) and checking the existence of central tendency data (normality). The values of coefficient of variation (CV) were classified as low (CV < 15 %), medium (15 < CV < 35 %) and high (CV > 35 %) variability. To spatial characterization of the soil properties (clay, phosphorus, potassium, pH and organic matter in water) were generated thematic maps and maps correction for P and K. The models have been structured using kriging interpolation method by means of Surfer 11® software. The use of PA tools was useful for characterization of soil properties on the lawn of previously established football. Clay contents ranged between 36 and 61 %. P and K showed high and medium spatial variability respectively, requiring correction variable rate whereas soil pH and organic matter showed low and medium spatial variability, respectively. The actions resulting from this research can contribute to the management of pitch football in Brazil. / Ainda são incipientes os estudos em gramados esportivos usando ferramentas de agricultura de precisão (AP). O objetivo deste estudo foi avaliar a variabilidade espacial de atributos do solo em um gramado de futebol utilizando técnicas de AP, com o intuito de proporcionar melhorias ao gramado. O estudo foi conduzido em um gramado de futebol com dimensões de 100m x 70m pertencente ao Esporte Clube Itapagé no município de Frederico Westphalen (RS). A área foi dividida em um grid amostral de 10 x 7m, totalizando 100 pontos amostrais, onde foram realizadas as coletas de solo, na profundidade de 0,00 - 0,10 m. Os atributos do solo analisados foram: teor de argila, fósforo (P), potássio (K), pH em água e matéria orgânica (MO). Os atributos foram analisados por meio de estatística descritiva obtendo-se as medidas de posição (mínimo, média e máximo) de dispersão (desvio padrão, coeficiente de variação, coeficiente de assimetria e coeficiente de curtose) e verificando-se existência de tendência central (normalidade) dos dados. Os valores de coeficiente de variação (CV) foram classificados como de variabilidade baixa (CV<15%), média (15<CV<35%) e alta (CV>35%). Para à caracterização espacial, foram gerados mapas temáticos dos atributos do solo (Argila, fósforo, potássio, pH em água e matéria orgânica) sendo, gerados mapas de correção para P e K. Os modelos foram estruturados utilizando-se método de interpolação krigagem, por meio do software Surfer 11®. A utilização de ferramentas de AP foram uteis para a caracterização dos atributos do solo no gramado de futebol previamente estabelecido. Os teores de argila variaram entre 36 e 61%. P e K apresentaram alta e media variabilidade espacial respectivamente, necessitando de correção em taxa variável enquanto que, o pH do solo e a matéria orgânica apresentaram baixa e media variabilidade espacial, respectivamente. As ações resultantes desta pesquisa podem contribuir para o manejo dos gramados de futebol do Brasil.

Algebraic topology of PDES

Al-Zamil, Qusay Soad January 2012 (has links)
We consider a compact, oriented,smooth Riemannian manifold $M$ (with or without boundary) and wesuppose $G$ is a torus acting by isometries on $M$. Given $X$ in theLie algebra of $G$ and corresponding vector field $X_M$ on $M$, onedefines Witten's inhomogeneous coboundary operator $\d_{X_M} =\d+\iota_{X_M}: \Omega_G^\pm \to\Omega_G^\mp$ (even/odd invariantforms on $M$) and its adjoint $\delta_{X_M}$. First, Witten [35] showed that the resulting cohomology classeshave $X_M$-harmonic representatives (forms in the null space of$\Delta_{X_M} = (\d_{X_M}+\delta_{X_M})^2$), and the cohomologygroups are isomorphic to the ordinary de Rham cohomology groups ofthe set $N(X_M)$ of zeros of $X_M$. The first principal purpose isto extend Witten's results to manifolds with boundary. Inparticular, we define relative (to the boundary) and absoluteversions of the $X_M$-cohomology and show the classes haverepresentative $X_M$-harmonic fields with appropriate boundaryconditions. To do this we present the relevant version of theHodge-Morrey-Friedrichs decomposition theorem for invariant forms interms of the operators $\d_{X_M}$ and $\delta_{X_M}$; the proofinvolves showing that certain boundary value problems are elliptic.We also elucidate the connection between the $X_M$-cohomology groupsand the relative and absolute equivariant cohomology, followingwork of Atiyah and Bott. This connection is then exploited to showthat every harmonic field with appropriate boundary conditions on$N(X_M)$ has a unique corresponding an $X_M$-harmonic field on $M$to it, with corresponding boundary conditions. Finally, we define the interior and boundary portion of $X_M$-cohomology and then we definethe \emph{$X_M$-Poincar\' duality angles} between the interiorsubspaces of $X_M$-harmonic fields on $M$ with appropriate boundaryconditions.Second, In 2008, Belishev and Sharafutdinov [9] showed thatthe Dirichlet-to-Neumann (DN) operator $\Lambda$ inscribes into thelist of objects of algebraic topology by proving that the de Rhamcohomology groups are determined by $\Lambda$.In the second part of this thesis, we investigate to what extent is the equivariant topology of a manifold determined by a variant of the DN map?.Based on the results in the first part above, we define an operator$\Lambda_{X_M}$ on invariant forms on the boundary $\partial M$which we call the $X_M$-DN map and using this we recover the longexact $X_M$-cohomology sequence of the topological pair $(M,\partialM)$ from an isomorphism with the long exact sequence formed from thegeneralized boundary data. Consequently, This shows that for aZariski-open subset of the Lie algebra, $\Lambda_{X_M}$ determinesthe free part of the relative and absolute equivariant cohomologygroups of $M$. In addition, we partially determine the mixed cup product of$X_M$-cohomology groups from $\Lambda_{X_M}$. This shows that $\Lambda_{X_M}$ encodes more information about theequivariant algebraic topology of $M$ than does the operator$\Lambda$ on $\partial M$. Finally, we elucidate the connectionbetween Belishev-Sharafutdinov's boundary data on $\partial N(X_M)$and ours on $\partial M$.Third, based on the first part above, we present the(even/odd) $X_M$-harmonic cohomology which is the cohomology ofcertain subcomplex of the complex $(\Omega^{*}_G,\d_{X_M})$ and weprove that it is isomorphic to the total absolute and relative$X_M$-cohomology groups.

Considerations on the economic impact of the 2010 FIFA World Cup on South Africa

Menezes, Mathew Gomes January 2010 (has links)
Mega-events are associated with significant positive implications such as enhanced international exposure of the host, improved infrastructure, increased tourist numbers, higher employment levels and tax revenues, greater feelings of patriotism among host region residents and integration of the host into the international community. Supporters of events have claimed that the occasions stimulate prominent economic gains for the host region. The economic and tourism growth that occurred in Barcelona following the 1992 Olympic Games is erroneously cited by proponents of hosting as an example of the potential benefits that an event can derive on the host. Those Games were not the sole driver of growth in the region. An analysis of previous mega-events, demonstrated that net benefits were not a necessary consequence of hosting. Comparison of pre-event estimates of the economic impact and their actual effects are universally divergent. The observation was validated by the consensus academic opinion that economic impact studies systematically overstate the benefits of hosting, and underestimate the costs. Further, different forward-looking studies of the same event, calculate vastly different predictions. The tools for calculating the economic impact, specifically Input-Output Analysis and Computable General Equilibrium, do not provide useful predictions given their dependence on the inaccurate data. With 2010 cost data having continually increased since 2003, determining the appropriate inputs to an I-O or CGE is problematic. It was identified that the weight given to the multiplier effect was also a factor in the amplification of the expected benefits. Given the poor data sets available as inputs to I-O and CGE models, the study concentrated on conducting a comprehensive Cost-Benefit Analysis of the determinants of the economic impact of the 2010 World Cup based on the premise that the identification of the relative costs and benefits of staging the event was regarded as a greater contribution to the body of knowledge on the topic. It can be expected that there will not be significant short-term economic gains; this study predicted a net cost of R8.4bn, which is marginally offset by short-term net intangible benefits. The short-term economic consequences of the 2010 World Cup are expected to be overshadowed by the long-term effects on revenues within the tourism industry. The image implication of hosting 2010 is the most salient factor in considering the economic impact of 2010, as an alteration in the national image can have long-term effects on FDI and tourism. It is however not a certainty that the international exposure that South Africa receives will be beneficial, in the instance that the World Cup is characterised by poor organisational measures or crime. The net impact of hosting is expected to be a function of the long-term benefits, which can be expected to exceed the short-terms costs, and derive a cumulative net benefit from staging 2010. The World Cup is however unlikely to stimulate the economic growth rate above levels that would have occurred had the event not been held in South Africa.

E - marketing of sports mega-events with specific reference to the 2010 Soccer World Cup

Radikonyana, Paul Shimane January 2013 (has links)
From an analysis of the literature it is apparent that there has been no concerted effort to date to undertake a coherent and integrated assessment of the application of e-marketing in sport mega-events. A strategic evaluation of the e-marketing initiatives implemented since 2000 during national and international mega events, indicates that e-marketing, in most instances, took place in a limited and fragmented manner. However a further analysis of these case studies provides valuable perspectives and lessons that could inform the research process related to e-marketing during the 2010 FIFA Soccer World CupTM. Against this background each of the selected sport mega-events since 2000 was investigated in terms of how e-marketing technology was used in the particular event, the e-marketing challenges experienced, the key e-marketing lessons learnt and the apparent e-marketing critical success factors related to these events. The theoretical context and the lessons learnt from previous mega-event case studies provided the background and frame of reference for the empirical research into the use of e-marketing during the 2010 Soccer World CupTM. The key envisaged outcome was to theoretically develop an e-marketing framework that can serve as a guideline to fully optimise e-marketing in future sports mega-events. The research findings were presented and the 16 critical e-marketing success factors (CSFs) that may contribute to the success of sport mega-events were identified. Specific conclusions were made based on the results obtained and specific actions were recommended for future additional research in the sport mega-events field. / Thesis (PhD)--University of Pretoria, 2013. / gm2013 / Tourism Management / PhD / Unrestricted

Sport, Corruption and Human Rights: the Case of FIFA / Sport, Corruption and Human Rights: the Case of FIFA

Shropshire, Kylea January 2014 (has links)
This master thesis dissertation analyzes what kind of humanitarian issues can arise when international sporting events, such as the World Cup, are connected with powerful, global sporting organizations such as FIFA. It asks whether or not FIFA takes into consideration the positive and negative consequences that such an event might have on human rights? Or if FIFA chooses to ignore these rights in preference of organizational gain? For my investigation I decided to choose FIFA because it is one of the most important sports organizations in the world and wields a great deal of power thanks to its corporate partners and football's worldwide appeal. My hypothesis is simple: Decisions made by FIFA are heavily influenced by endemic corruption throughout the organization that does not prioritize citizen rights or human rights development more generally.

The identification of batting trends through a comparative analysis in Twenty20 cricket between Varsity Cup winning teams and the University of the Western Cape Cricket Club from its origin in 2015 – 2017

Ramoo, Romano January 2020 (has links)
Magister Artium (Sport, Recreation and Exercise Science) - MA(SRES) / Over the years cricket has developed from a traditional and conservative game into an extremely lucrative sport, which requires a great deal of professionalism in all surrounding areas. In recent years cricket has evolved and resulted in the emergence of Twenty20 cricket. The aim of this study focused on identifying batting trends through a comparative analysis between Varisty Cup winning teams and the University of the Western Cape Cricket Club between the age group of 18 – 25. The study used a quantitative research approach with a content analysis methodology research design. Nine key batting variables were analysed in three phases of a cricket match (Powerplay, Middle overs and Death overs) between winning teams and the University of the Western Cape Cricket Club to establish the magnitude of differences (Cohen’s effect size). The top indicators for success in the tournament were averaging a higher number of boundary fours, accumulating a higher number of single runs throughout the match, averaging a high number of sixes during the Middle and Death Overs of a batting innings and accumulating two’s throughout all three phases of a match. The overall summary of this study’s results navigates to a batting strategy that should focus on batting trends by maintaining a higher batting run rate, target to scoring more boundary fours and sixes, good running between the wickets to accumulate two’s, select batsmen with a low dismissal rate and select batsmen with a high single scoring rate [equates to better strike rotation].

Estimating Risks of Pharmaceutical NSAID Mixtures in Surface Waters through Risk Cups : – Implications for Sustainability

Mandahl, Per January 2020 (has links)
Background: Use of pharmaceuticals can lead to unchanged or metabolite residues in surface water that may result in negative environmental effects. Sweden has adopted the Generational goal defining direction and changes needed to become a sustainable nation, these align with the UN Sustainable Development Goals (SDGs). Sweden collects and analyzes samples for pharmaceuticals and other contaminants in surface water. Aim: To estimate risks connected to pharmaceuticals in complex mixtures, exemplified by nonsteroidal anti-inflammatory drugs (NSAIDs), and discuss how this can be used to influence the actions needed to reach the Generational goal and the SDGs of Agenda 2030. Methods: Here, measured environmental concentrations (MECs) of the NSAIDs diclofenac, ibuprofen, ketoprofen, and naproxen in Swedish surface waters and in Uppsala’s Fyris River were accessed from a database and used in conjunction with predicted no-effect concentrations (PNECs) from the literature to derive risk quotients(RQ=MEC/PNEC). For all drugs a standardized PNEC derived from OECD guideline base-set tests were found, and for diclofenac and ibuprofen also non-traditional guideline PNECs were identified. Risk cups applied by summation of MEC/PNEC-risk quotients are considered safe if the sum of RQ &lt;1, and as proposed inSOU 2019:45, if one chemical adds more risk than 0.1 to the risk cup it would be better to substitute it for another, if possible. Results and Discussion: Standardized PNECs derived from OECD guideline base-set tests were more than 60-fold greater than non-traditional PNECs for diclofenac and ibuprofen, affecting their individual RQ contribution and total sum of RQ. Based on the non-traditional PNECs, the sum of RQ were more than or near 1 in some cases in Fyris River and elsewhere, thus indicating risk to biota especially in 2010. Diclofenac and ibuprofen typically contributed more to Risk cups than did ketoprofen and naproxen. Especially diclofenac should be considered for substitution, if possible. Swedish sales data indicate at least one more NSAID compound suitable for analysis. In addition, more than 70 pharmaceuticals were identified in Fyris River, adding to pressure on environment from NSAIDs. Risk cups are conservative and require sparse data relative to other methods, and thus can be used to prioritize further efforts. A difficulty is to find relevant ecotoxicological data for pharmaceuticals and therefore an open access database would be of value, preferably complemented with sales data for APIs. However, since a default RQ-value of 0.1 was suggested in SOU 2019:45, a lack of data would not hinder action. Use of risk cups makes it possible to work toward e.g., sustainable production practices benefiting SDG 12. Inaction after identifying a problem conflicts with SDGs 6 and 12, since it would lead to less clean water and more sanitation issues and non-sustainable consumption and production. Conclusion: Risk cups as applied here are suitable as a first tier of pharmaceutical mixture risk estimation since they are quick to perform and demand less data than other methods. Because of their dependence on PNECs, it is important to use a relevant effect test, with results preferably published in an open access database. Diclofenac’s non-traditional risk quotient indicate that the ecological status of the Fyris River is at risk, supporting the official moderate ecological status classification. This thesis suggests an additional NSAID, etoricoxib, as a possible candidate for future studies, based on the number of other NSAIDs on the market and sales numbers, pointing at the usefulness of sales data for a better understanding of risk. In addition to the NSAID group, other pharmaceuticals, active metabolites, and non-pharmaceutical chemicals add to the pressure on the environment. Data on the risk cups and risk quotients can be used as a basis for improvements at sewage treatment plants and factories as well as for launching informative campaigns to physicians and the general public, actions which all may lead to a more sustainable future.

The control of an open-circuit, floating cup variable displacement pump

Achten, Peter, Eggenkamp, Sjoerd January 2016 (has links)
The floating cup principle is a general hydrostatic principle for both constant and variable displacement pumps and motors, as well as for hydraulic transformers. In this paper, the focus will be entirely on the control of the displacement of the variable 28 cc Floating Cup pump (FCVP28). The floating cup principle features two opposed swash plates, for which both angular positions need to be controlled in order to cover the entire range from zero to full displacement. The results of both extended numerical analysis as well as simplified linearized models will be compared to test results on a 28 cc FCVP. Special emphasis will be on the dynamic behaviour of the displacement control.
