Tribuna de Petrópolis: trajetória e representação na cidade imperial: imprensa e identidade de Petrópolis em 100 anos de jornal local

Fundada em 1902, a Tribuna de Petrópolis acumula 108 anos de publicação na cidade serrana do interior do Estado do Rio de Janeiro. Sendo um jornal local, de circulação restrita aos limites do município, sua existência por mais de um século reflete o esforço de seus diretores pela superação de crises e também pela manutenção de um poder simbólico de identidades sobre a cidade. Analisa-se a trajetória do jornal a partir de três fases de existência e da relação que o mesmo estabeleceu com Petrópolis em cada uma delas: no início do século XX, quando de sua fundação, momento em que representa o reposicionamento político do Grupo de Petrópolis após a perda da capital para Niterói; na metade do século, entre os anos 1950 e 1970, quando o jornal atravessa uma profunda crise e tem sua falência decretada; e nas décadas finais do século XX, quando o veículo se reorganiza e, sob o comando de herdeiros da Família Imperial, constrói para si uma nova relação de identificação e representação com a cidade de Petrópolis. Como jornal-empresa e parte de um conglomerado de comunicação, a Tribuna de Petrópolis chega ao século XXI e se estabelece como instituição pautada por escolhas e decisões estratégicas de administração e relacionamento com o mercado local de anunciantes.

Se um taco e uma bola custam R$110, e o taco custa R$100 a mais do que a bola, quanto custa a bola?

O objetivo desta tese é investigar cuidadosamente a interação entre a intuição e a razão, propondo um novo modelo cognitivo que explicaria a existência, interação e comportamento dos chamados "dois sistemas" que, supõe-se, coabitem a mente humana. O modelo que será postulado nesta dissertação integra e explica estes dois sistemas; e o sistema NUMBO derivado dos projetos de Hofstadter (1995) é capaz de demonstrar sua plausibilidade psicológica e sua tàctibilidade de modelagem e simulação em uma arquitetura computacional. Serão utilizadas variações do problema da bola e do taco, pertencente ao Cognitive Reflection Test proposto por Frederick (2005), para ilustrar como o processo pelo qual as pessoas passam pode se dar, bem como serão utilizados resultados da psicologia experimental, para validar a plausibilidade psicológica dos mecanismos propostos. A contribuição deste trabalho é, portanto, explicitar as "coleções de processos" que estão operando em cada "caixa-preta" do sistema 1 ou sistema 2. Desta fom1a, pretende-se dar um pequeno passo em direção à teorias mais elaboradas sobre intuição e razão.

Operações off-balance sheet e instrumentos híbridos: utilização pelas empresas que compõe o IBrX-100 e sua relação com o rating e a internacionalização das empresas brasileiras

Esta dissertação busca identificar a utilização de operações off-balance e instrumentos híbridos pelas empresas brasileiras. Seu objetivo é, além da utilização, verificar se o índice de transnacionalidade e o rating de crédito influenciam na decisão de utilizar ou não tais operações e instrumentos. Para isso, foram observadas as demonstrações financeiras e ratings das empresas participantes do índice IBrX-100 no período dos últimos três anos (2009, 2010 e 2011). Já para considerar o efeito da utilização das operações e instrumentos em razão do quão internacionalizadas são as empresas, este trabalho utiliza como critério a participação das empresas no ranking das transnacionais brasileiras no mesmo período acima citado. A análise revela que as empresas brasileiras mais internacionalizadas são mais sofisticadas que as menos internacionalizas e consequentemente se utilizam mais de instrumentos híbridos e operações off-balance. Ainda nesta linha, quando se divide as empresas por quartil, se chega ao resultado esperado que quanto mais internacionalizada a empresa, mais ela se utiliza destas operações e instrumentos. Além disso, também conclui que o rating influencia na utilização destes instrumentos e operações; quanto pior, mais a empresa se utiliza. Isso ocorre quando a métrica é o rating nacional, e não foram encontradas fortes evidências em relação ao rating estrangeiro.

Anticipatory effects in the FTSE 100 index revisions

This paper examines the price impact of trading due to expected changes in the FTSE 100 index composition. We focus on the latter index because it employs publicly-known objective criteria to determine membership and hence it provides a natural context to investigate anticipatory trading e ects. We propose a panel-regression event study that backs out these anticipatory e ects by looking at the price impact of the ex-ante proba-bility of changing index membership status. Our ndings reveal that anticipative trading explains about 40% and 23% of the cumulative abnormal returns of additions and deletions, respectively. We con rm these in-sample results out of sample by tracking the performance of a trading strategy that relies on the addition/deletion probability estimates. The perfor-mance is indeed very promising in that it entails an average daily excess return of 11 basis points over the FTSE 100 index.

Indexing stock portfolios in Brazil: tracking the IBOVESPA and the FGV 100

Indexing is a passive investment strategy in which the investor weights bis portfolio to match the performance of a broad-based indexo Since severaI studies showed that indexed portfolios have consistently outperformed active management strategies over the last decades, an increasing number of investors has become interested in indexing portfolios IateIy. Brazilian financiaI institutions do not offer indexed portfolios to their clients at this point in time. In this work we propose the use of indexed portfolios to track the performance oftwo ofthe most important Brazilian stock indexes: the mOVESPA and the FGVIOO. We test the tracking performance of our modeI by a historical simulation. We applied several statistical tests to the data to verify how many stocks should be used to controI the portfolio tracking error within user specified bounds.

Especificação de um modelo para explicação e projeção de retornos do IBRX-100

Neste trabalho, propomos uma especificação de modelo econométrico na forma reduzida, estimado por mínimos quadrados ordinários (MQO) e baseado em variáveis macroeconômicas, com o objetivo de explicar os retornos trimestrais do índice de ações IBRX-100, entre 2001 e 2015. Testamos ainda a eficiência preditiva do modelo e concluímos que o erro de previsão estimado em janela móvel, com re-estimação de MQO a cada rodada, e utilização de VAR auxiliar para projeção dos regressores, é significativamente inferior ao erro de previsão associado à hipótese de Random Walk para o horizonte de previsão de um trimestre a frente.

Estudo da molhabilidade de tecidos 100% poliéster tratados em plasma N2/O2 em função do seu envelhecimento natural

This work reports the influence of the poly (ethylene terephthalate) textile surface modification by plasmas of O2 and mixtures (N2 + O2), on their physical and chemical properties. The treatment was carried out in a vacuum chamber. Some parameters remained constant during all treatment, such as: Voltage 470 V; Pressure 1,250 Mbar; Current: 0, 10 A and gas flow: 10 cm3/min. Other parameters, such as working gas composition and treatment time, were modified as the following: to the O2 plasma modified samples only the treatment time was changed (10, 20, 30, 40, 50 and 60 minutes). To the plasma with O2 and N2 only the chemical concentrations were changed. Through Capillary tests (vertical) an increase in textile wettability was observed as well as its influence on aging time and its consequence on wettability. The surface functional groups created after plasma treatments were investigated using X-ray Photoelectron Spectroscopy (XPS). The surface topography was examined by scanning electron microscope (SEM)

Impacto da estratégia saúde da família com equipe de saúde bucal sobre indicadores de saúde bucal: análise em municípios do nordeste com mais de 100 mil habitantes

This study examined in municipalities of Northeast of Brazil with more than one hundred thousand people who incorporation of Oral Health Teams (OHT) into the Family Health Strategy (FHE) the possible impact on oral health indicators. Sought to answer whether implementation OHT brought the best indicators of health problems and coverage, compared to areas without coverage by the FHE through a community trial in parallel, quasi-randomized. In each of the municipalities surveyed were 20 census tracts, 10 were located in areas covered by oral health teams in the ESF and 10 industries in areas not covered. The final sample consisted of 59.221 individuals. We compared oral health indicators related to health problems, access to services and coverage of oral health actions. The analysis strategy was based on the calculation of prevalence ratios and confidence intervals, adjusted for confounding factors through Poisson regression with robust variance. It also has measured the association between an indicator of social inequality for comparison between areas. The best results are associated with indicators of access and coverage of oral health actions at the expense of the indicators of health problems, suggesting a possible maintenance of a traditional model of practice yet. The results also suggest a possible effect of a specific policy in the area of primary care on inequality in access. From the discussions presented throughout this work, we can see that the impact analysis of public policy, obtained by comparing areas with and without the intervention, not only captures the effect on the target population, but other dimensions of organization service and therefore should be understood as one of the analytical possibilities related to the management

Características físicas, somatotipo e desempenho de corredores de 100 e 400 metros no Rio Grande do Norte

Objective: The aim of the study was to investigate physical characteristics and to examine association between somatotype and performance in collegiate runners of 100 m and 400 m. Methods: The sample, male runners (n=39) competing at the regional level in the state of Rio Grande do Norte, Brazil, had height, body mass, skinfolds, limb circumference and skeletal breadths measured. Then, the somatotype was calculated by Health-Carter method. Races (100 m and 400 m) were held to assess athletic performance. Descriptive statistics were calculated for the total sample, as well as for the 100 m and 400 m groups, and established four subgroups, named quartiles. For analysis between groups of runners (100 m x 400 m) was used Student's t test for independent samples. To examine the relationship between the race times and anthropometric variables, was used the Pearson correlation test. The somatotype dispersion distance and somatotype spatial distance were calculated among subgroups. One-way analysis of variance, the Wilcoxon test followed of Tukey post test, and correlation analysis were used with a significance level of p<0.05. Results: Somatotype with mesomorphy and ectomorphy dominance was exhibited by 100 m and 400 m athletes. Endomorphy was low in both groups, especially in 400m runners, who had more elongated body types than 100 m runners. When separately compared by athletic performance quartile, 100 m sprinters of better qualifications (G100-G1) had somatotype with dominant mesomorphy, whereas 400 m runners had somatotype with dominant ectomorphy. A significant correlation (r = -0.55, p=0.008) between calf circumference and 100 m race times was observed showing the importance of muscularity, whereas a significant correlation was found between height and 400 m race times (r = -0.53, p=0.02) showing the importance of linearity. Conclusion: Runners of 100 and 400 may show differences in physical characteristics, depending on the level of athletic performance. Anthropometric periodic evaluations may help in the training process of these athletes. However, more specific assessment parameters should be taken into account, because somatotype by itself has not power to predict whether an individual will succeed in racing speed

Micropartículas poliméricas à base de xilana e Eudragit® S-100 contendo mesalazina visando à liberação cólon-específica

Colon-specific drug delivery systems have attracted increasing attention from the pharmaceutical industry due to their ability of treating intestinal bowel diseases (IBD), which represent a public health problem in several countries. In spite of being considered a quite effective molecule for the treatment of IBD, mesalazine (5-ASA) is rapidly absorbed in the upper gastrointestinal tract and its systemic absorption leads to risks of adverse effects. The aim of this work was to develop a microparticulate system based on xylan and Eudragit® S- 100 (ES100) for colon-specific delivery of 5-ASA and evaluate the interaction between the polymers present in the systems. Additionaly, the physicochemical and rheological properties of xylan were also evaluated. Initially, xylan was extracted from corn cobs and characterized regarding the yield and rheological properties. Afterwards, 10 formulations were prepared in different xylan and ES100 weight ratios by spray-drying the polymer solutions in 0.6N NaOH and phosphate buffer pH 7.4. In addition, 3 formulations consisting of xylan microcapsules were produced by interfacial cross-linking polymerization and coated by ES100 by means of spray-drying in different polymer weight ratios of xylan and ES100. The microparticles were characterized regarding yield, morphology, homogeneity, visual aspect, crystallinity and thermal behavior. The polymer interaction was investigated by infrared spectroscopy. The extracted xylan was presented as a very fine and yellowish powder, with mean particle size smaller than 40μm. Regarding the rheological properties of xylan, they demonstrated that this polymer has a poor flow, low density and high cohesiveness. The microparticles obtained were shown to be spherical and aggregates could not be observed. They were found to present amorphous structure and have a very high thermal stability. The yield varied according to the polymer ratios. Moreover, it was confirmed that the interaction between xylan and ES100 occurs only by means of physical aggregation
