Srovnání vegetace sjezdových tratí s umělým a přírodním sněhem v CHKO Bílé Karpaty a v CHKO Beskydy / Comparison of vegetation on ski slopes with artificial or natural snow in CHKO Bílé Karpaty and CHKO Beskydy

KOCKOVÁ, Jitka January 2011 (has links)
Vegetation cover of 24 ski slopes both with artificial and natural snow was studied; on each slope 5 phytocenological relevés measuring 4 x 4 metres were taken. A method of direct gradient analysis (RDA) was used to detect differences in composition of phytocenological reléves on the ski slopes with natural or artificial snow. However, no impact of use of artificial snow on vegetation was identified. During the winter season of 2009 and of 2010 samples of artificial and natural snow were taken for chemical analyses. The chemical composition differed significantly; artificial snow contained more NO3-, SO42- and Ca2+ ions and its pH was more alkaline in comparison with natural snow.

[en] STATE SPACE MODELS FOR IBNR RESERVES ESTIMATION: ROW-WISE STACKING THE RUNOFF TRIANGLE / [pt] ESTIMAÇÃO DE RESERVAS IBNR POR MODELOS EM ESPAÇO DE ESTADO: EMPILHAMENTO POR LINHAS DO TRIÂNGULO RUNOFF

RODRIGO SIMOES ATHERINO 15 June 2009 (has links)
[pt] Este trabalho versa sobre previsão de reservas do tipo IBNR levando-se em conta uma ordenação diferente do triângulo de runoff incremental. Esta se dá por linhas empilhadas, originando, assim, uma série temporal univariada repleta de valores faltantes, cuja soma desses valores constitui o IBNR a ser estimado. Duas abordagens de estimação, inteiramente baseadas na teoria dos modelos em Espaço de Estado e do filtro de Kalman, são desenvolvidas, implementadas com dados reais de empresas seguradoras, e comparadas entre si e a outros métodos de estimação já consagrados na literatura atuarial. A primeira abordagem pauta-se no cálculo da matriz de covariâncias condicionais das componentes do IBNR, e a segunda é um processo de obtenção do IBNR por acumulação. Os resultados obtidos revelam, para as abordagens propostas, os seguintes pontos sumários: (i) plena eficiência e viabilidade computacional; (ii) sistemático ganho em termos de acurácia do IBNR estimado; e (iii) abrangência no que diz respeito às possibilidades de modelagem estatística dos dados de IBNR. / [en] This work deals with prediction of IBNR reserves under a different ordering of the non-cumulative runoff triangle. This is accomplished by stacking the rows, which results in a univariate time series with several missing values, whose corresponding sum is in fact the IBNR. Two estimation approaches, entirely based on state space methods and Kalman filtering, are developed, implemented with real data, and compared with some well established estimation methods for IBNR. The first approach consists in obtaining the conditional covariance matrix of the IBNR components, and the second tackles the IBNR estimation under an accumulation process. Three remarks emerge from the empirical results: (i)computational feasibility and efficiency; (ii)precision improvement for IBNR estimation; and (iii)flexibility in which concerns the IBNR modelling framework.

A relevância do tema deve-se ao fato de a corrida de rua ter apresentado, nos últimos anos, um crescimento acelerado do número de participantes, assim como, do total de provas oferecidas no país. Diante deste fenômeno esportivo e social, busca-se ampliar a discussão partindo da análise das campanhas publicitárias "It's Runderful" da marca Mizuno e "Vem Junto” da marca Nike — ambas produzidas e veiculadas em território nacional. Pretende-se, portanto, discutir questões que envolvem o papel social do esporte e a importância da publicidade como produção midiática que reflete elementos culturais e simbólicos por meio de suas formações discursivas. Como abordagem metodológica serão empregados os fundamentos da análise do discurso de linha francesa em diálogo com os conceitos da sociologia do esporte. / This study intends to understand the way that Brazilian advertising represents the road run sport in its discourse. The theme is relevant because the road run has a rapid growth in the number of participants and competitions offered in recent years in Brazil. Faced with this sport and social phenomenon, we sought to discuss the theme from the analysis of Mizuno’s advertising campaign named "It's Runderful" and Nike's advertising campaign named "Vem Junto", both produced and transmitted in national territory, and discuss issues that involve the social relevance of sport and the importance of advertising as a media production that reflects cultural and symbolic elements through its discursive formations. As a methodological approach will be employed the fundamentals of Discourse Analysis (French DA) in dialogue with the concepts of the sociology of sport. / CAPES: 1648016

Cota de inundação e recorrência para a enseada do Itapocorói e praia de Morro dos Conventos, Santa Catarina

Silva, Guilherme Vieira da January 2012 (has links)
Este trabalho apresenta o cálculo da cota de inundação para a Enseada do Itapocorói e para a praia de Morro dos Conventos, litoral do Estado de Santa Catarina. Para atingir os objetivos desse trabalho, a cota de inundação foi calculada através da soma das marés meteorológica e astronômica e do wave run-up. Foi utilizada uma base de 60 anos (horária) de dados de marés e ondas, além de dados de batimetria e topografia das praias. Com o intuito de se obter dados mais realistas do wave run-up, os parâmetros ondulatórios da base de dados foram transferidos de águas profundas para próximo da costa com a utilização do modelo SWAN (Simulating Waves Nearshore). A Enseada do Itapocorói foi dividida em quatro setores (exposto, semiexposto, semiprotegido e protegido) em função dos diferentes graus de exposição à ação de ondas, sendo as equações calibradas para cada setor. A partir dos resultados para Enseada do Itapocorói, notou-se que quanto mais exposta a praia, melhor as equações existentes representavam o wave run-up, assim, para a praia de Morro dos Conventos foi utilizada a equação mais aceita na literatura sem calibração. A cota de inundação instantânea foi calculada para cada hora da série de 60 anos somando-se o wave run-up às marés astronômicas e meteorológicas. Sobre a série de cota de inundação instantânea, para ambas as áreas, foi calculada a cota atingida durante 50% do tempo e por eventos extremos com recorrência de 50, 100 e 200 anos. A estas foi adicionada a previsão de elevação do nível do mar de longo prazo para o mesmo período. A cota atingida durante 50% do tempo na Enseada do Itapocorói foi de 1,35 m no setor exposto, enquanto nos setores semiexposto, semiprotegido e protegido foi de 1 m, 0,9 m e 0,7 m respectivamente. Também, o setor exposto foi o que apresentou as maiores cotas atingidas, sendo 3,45 m, 3,85 m e 4,45 m com tempo de recorrência de 50,100 e 200 anos respectivamente. No setor semiexposto, os valores calculados foram de 2,85 m (50 anos), 3,25 m (100 anos) e 3,9 m (200 anos). No setor semiprotegido, as cotas com tempo de recorrência de 50, 100 e 200 anos foram de 2,65 m, 3,05 m, 3,75 m respectivamente. Já o setor protegido apresentou as menores cotas entre os setores, 2,4 m, 2,85 m e 3,5 m para 50, 100 e 200 anos de tempo de recorrência. Considerando a extensão da área costeira que possui um levantamento de topografia do terreno, 2,4 % da área é inundada durante 50% do tempo, subindo para 26%, 29% e 33% nos casos de recorrência com 50, 100 e 200 anos. A cota atingida na praia de Morro dos Conventos durante 50% do tempo é de 1,1 m, já as cotas calculadas para os tempos de recorrência de 50, 100 e 200 anos foram de 4,2 m, 4,6 m e 5,35 m respectivamente. E, da mesma forma, a área costeira com levantamento topográfico teve 15% de superfície é inundada em 50% do tempo, passando para 85%, 91% e 96% da área total analisada com 50, 100 e 200 anos de tempo de recorrência. A metodologia proposta neste trabalho contribui para o planejamento de zonas costeiras, à medida que indica áreas afetadas por inundação aos eventos extremos. A apresentação de cartas contendo esse tipo de informação em ambiente de SIG facilita a tomada de decisão e o entendimento da área por determinado evento extremo. / The goal of this study is to determine the inundation levels at Ensenada do Itapocorói and Morro dos Conventos beaches, located in Santa Catarina State. This was accomplished through the calculation of the inundation level as the sum of astronomical and meteorological tides and wave run-up. The database for this study included -60 years of hourly waves and tides, bathymetric and topographic data. The instantaneous sea level has been defined for each hour of the data series through the summation of astronomical and meteorological tides. To determine more realistic wave run-up data, the wave parameters have been propagated to shallower water using the SWAN (Simulating WAves Nearshore) model. Published equations were used and results were compared with measured data at a headland bay beach (Enseada do Itapocorói); furthermore, the equations have been calibrated for four sectors of the bay (exposed, semi-exposed, semi-protected and protected). Morro dos Conventos is an exposed beach, comparable to those for which the equations have been developed, so the raw, un-calibrated equations were applied for this site. The inundation level was calculated for each hour of the 60 year-long series by summing the run-up values to obtain the instantaneous level. Over the series of inundation levels, the area inundated during 50% of the time, and the return period for this inundation, have been calculated for 50, 100 and 200 years. The sea-level rise prediction for each calculated period has also been incorporated in order estimate the area likely to be inundated by future events. For Enseada do Itapocorói, the inundation level reached 50% of the time was 1,35 m in the exposed sector, 1 m in the semi-exposed sector, 0,9 m in the semi-protected sector and 0,7 in the protected sector. The exposed sector demonstrated the highest values of inundation, 3,45, 3,85 and 4,5 m for 50, 100 and 200 years of return period respectively. At the semi-exposed sector, the values calculated were 2,85 (50 years), 3,25 (100 years) and 3,9 (200 years) m. At semi-protected sector, inundation levels for the 50-, 100- and 200-year return period intervals were 2,65, 3,05 and 3,75 m, respectively. At the protected sector the lowest levels were reached: 2,4, 2,85 and 3,5 m for 50-, 100- and 200-year return period intervals. 2,4% of the total area for which topographic data is available would be inundated during 50% of the time, increasing to 26%, 29% and 33% for 50-, 100- and 200-year return periods. At Morro dos Conventos, the level of inundation reaches 1,1 m 50% of the time;, for 50,100 and 200 years the level rises to 4,2, 4,6 and 5,36 m respectively. Approximately 15% of the area for which topographic data is available would be area is inundated during 50% of the time, 85% with a 50 year return period, 91% with a 100-year period and 96% with a 200 year period.

Determinantes da performance de longo prazo de IPOs no mercado brasileiro

Navarro Filho, Danilo Mattes January 2016 (has links)
Estudos recentes, realizados principalmente no mercado norte-americano, trazem in-dícios de fatores determinantes para o resultado de longo prazo das emissões primá-rias de ações (IPOs, do inglês Initial Public Offerings). Porém, trabalhos com esse enfoque no mercado brasileiro ainda são escassos e inconclusivos, pois utilizam pe-quenas bases de dados e analisam horizontes de tempo de até dois anos. Buscando ampliar a análise de IPOs no mercado brasileiro, o objetivo desta dissertação foi es-tudar os determinantes do desempenho de longo prazo das IPOs realizadas na Bolsa de Valores de São Paulo com horizontes de tempo de três e cinco anos após o pri-meiro dia de negociações. A amostra foi composta por 97 emissões primárias de ações ocorridas entre 2004 e 2012 para o horizonte de três anos e 77 ocorridas entre 2004 e 2010 para o horizonte de cinco anos. O cálculo de retorno de longo prazo seguiu a metodologia de Buy-and-Hold Abnormal Return (BHAR), ajustado ao Ibo-vespa, e os possíveis determinantes do BHAR das IPOs foram submetidos a análises multivariadas através de estimações pelo método de Mínimos Quadrados Ordinários (MQO). Os resultados levam à conclusão de que o desempenho de longo prazo das IPOs brasileiras está positivamente relacionado com: 1) a Idade das firmas, 2) o nível de Governança Corporativa, 3) o Setor e 4) o Desempenho Operacional pós IPO. Pôde-se concluir, também, que o desempenho de longo prazo das IPOs está negati-vamente relacionado com: 1) o Retorno Anormal do Primeiro Dia de negociações, 2) a Quantidade de IPOs realizadas no Ano e 3) o Percentual de Investidores Institucio-nais na emissão primária. Os testes de robustez realizados apontam para uma relação também positiva entre o Crescimento do PIB do período pré IPO com o resultado de longo prazo das ações. / Recent studies, conducted mainly in the North American market, have presented evi-dence regarding decisive factors for the long-run performance of Initial Public Offerings (IPOs). However, the number of similar studies applied in the Brazilian market is yet limited and inconclusive, because they employ reduced databases and short time win-dows up to two years. Seeking to extend the analysis of IPOs in the Brazilian market, the purpose of this study was to explore the determinants of the long-run performance of IPOs held at BM&F Bovespa, with time windows of three and five years after the first trading day. The sample was composed of 97 initial public offerings occurred be-tween 2004 and 2012 for three-year horizon and 77 occurred between 2004 and 2010 for the five-year horizon. The long-run return calculation followed the methodology of Buy-and-Hold Abnormal Return (BHAR), adjusted to the Ibovespa index, and the pos-sible determinants of BHAR related to IPOs were subjected to multivariate analysis using Ordinary Least Squares (OLS) approach. The results lead to the conclusion that the long-run performance of Brazilian’s IPOs is positively related with: 1) Age of the Firms, 2) the level of Corporate Governance, 3) Sector and 4) post IPO Operating Performance. In addition, it was noticed that the long-run performance of IPOs is neg-atively related with: 1) the Abnormal Return of the First Trading Day, 2) the IPO amount held in the year and 3) percentage of Institutional Investors the IPO. Robustness tests were performed, and their conclusions highlighted a positive relationship between GDP growth of previous IPO period with the long-run performance.
