Flutuações dos preços dos ativos financeiros: mensuração da reação da política monetária aos choques do mercado acionário

O mercado acionário brasileiro tem demonstrado consistente desenvolvimento ao longo dos últimos anos. A teoria econômica aponta uma inter-relação entre os resultados deste mercado e a estrutura macroeconômica. Através da metodologia de Rigobon e Sack (2003), o presente estudo avalia o impacto contemporâneo do mercado acionário sobre a taxa Selic de juros. A contribuição deste trabalho é a de encontrar indícios de que um choque não esperado que cause 1% de valorização no retorno do mercado acionário provoque uma queda de 0,019% na taxa Selic de juros. Os resultados parecem ser de pequena escala, quando comparados com os valores obtidos em outros países.

A tradução da tradição : gaúchos, guaxos e sombras : o regionalismo revisitado de Luiz Carlos Barbosa Lessa e de Ricardo Güiraldes

Este estudo propõe a análise da permanência do gaúcho como portador de uma identidade regional e cultural em nossos dias. O estereótipo, que teve origem nas fronteiras da história do Rio da Prata, segue um desenvolvimento muito peculiar no Rio Grande do Sul. Como no caso argentino, com Ricardo Güiraldes e seu Don Segundo Sombra, a literatura dos escritores regionais e tradicionalistas do sul do Brasil, entre eles, Barbosa Lessa, perpetuou o gênero que se iniciara com a gauchesca do século XIX.O tipo muito particular de tradução cultural – a “transcriação” – que os escritores fizeram sobre a figura do gaúcho em suas obras auxiliou toda uma geração a significar sua identidade. Assim, a literatura, longe de manter símbolos de uma velha tradição, desenvolveu-a como uma nova forma de resistência de uma cultura regional no mundo globalizado.

A era negra do Vale: café, escravos e senhores em Piraí

O presente trabalho analisa cinco inventários dos maiores produtores de café no município de Piraí, no Vale do Paraíba, entre os anos de 1839 e 1848, totalizando quase dois mil escravos. A partir de uma perspectiva de historia econômica pretende-se mostrar que a produção cafeeira permitia o acúmulo de capital e seu reinvestimento na expansão da monocultura. O estudo dos cativeiros também busca evidenciar que os cativos, africanos em sua maioria, eram agentes na formação de suas famílias, mantendo um espaço de sociabilidade baseado na memória e na construção de uma nova identidade afro-brasileira.

Influência de variáveis arquitetônicas no desempenho energético de hotéis no clima quente e úmido da cidade de Natal/RN

This master thesis aims to assess the influence of the design decisions on the energy building performance of hotels. The research is based on the integration of field study and computer simulation. Firstly, a detailed field study is carried out to identify the characteristics of hotels in Natal, Rio Grande do Norte. The items assessed are occupancies, light and equipment densities, types of air conditioning, total and monthly energy consumption, among others. A second and more comprehensive field study is carried out to identify the range of occurrence of architectural variables, with a larger number of buildings. A base case is modelled in VisualDOE, based on the first field study. Then, a first set of simulations are run to explore the sensitivity of the variables on the energy consumption. The results analyses were the base of a second set of simulations, which combined the most influential variables. The results of 384 models were assessed, and the impacts of design decisions were quantified. The study discusses tendencies and recommendations, as well as the methods advantages and disadvantages

Efeito da adição de carbonatos em formulação de massa para revestimento cerâmico utilizando matérias-primas do Piauí

Piauí state is a major producer of traditional red ceramic burning as bricks, tiles and ceramic tiles, with its main production center located in the city of Teresina. The state has large reserves of raw materials that can be used in the ceramic coating as clays, quartz, talc and carbonates. However, in the preparation of ceramic bodies using only a mixture of clays with different characteristics. The study aims to evaluate the effect of adding two types of carbonates in the ceramic semiporous mass coating produced in Piauí and then to verify the potential use of these carbonates as supplementary raw material product manufactured or the feasibility of obtaining a ceramic plate that meets the specifications for the porous coating. For this, were characterized the ceramic Piauí coating mass, a calcitic carbonate and a dolomitic, were made in the levels of 2, 4, 8, 16, and 32%. The masses were formed by pressing and burneds in two environments: a laboratory furnace (1080°C, 1120°C, 1140°C, and 1160°C) and an industrial furnace (1140°C). Then, following tests of linear shrinkage water absorption, apparent porosity, bulk density and flexural strength. Furthermore, the fired specimens were tested for their macrostructure and microstructure. The results showed the possibility of using the carbonate in ceramic mass flooring produced in Piauí, as added in small proportions improved dimensional stability and increased mechanical strength of ceramics pieces. It also proved itself possible to produce porous coating when added in higher levels

Efeito da adição de feldspato e/ou resíduo de caulin em formulações à base de argila ilítica

The red pottery industry in Piauí state is well developed and stands out at the national context for the technical quality of its products. The floor and wall tile industry, however, is little developed since the state has only one company that produces red clay-based ceramic tiles. This thesis aims at using the predominantly illitic basic mass of the above mentioned industry, with the addition of feldspar and/or kaolin residue in order to obtain products of higher technical quality. Kaolin residue consists basically of kaolinite, muscovite mica and quartz; the feldspar used was potassic. In this experiment, basic mass (MB) was used for experimental control and fifteen formulations codified as follows: F2, F4, F8, F16, F32, FR2, FR4, FR8, FR16, FR32, R2, R4, R8, R16 and R32. All raw materials were dry-milled, classified, formulated and then humidified to 10% water. Thereafter, test samples were produced by unixial pressing process in a rectangular steel matrix (60.0 x 20.0 x 5.0) mm3 at (25 MPa). They were fired at four temperatures: 1080°C, 1120°C, 1160°C, with a heating rate of 10°C/min during up to 10 min in an electric oven, and the last one in an industrial oven with a peak of 1140°C, aim ing to confirm the results found in laboratory and, finally, technological tests were performed: MEA, RL, AA, PA, TRF and PF. The results revealed that the residue under study can be considered a raw material with large potential in the industry of red clay-based ceramic tiles, since the results found both in laboratory and in the industry have shown that the test samples produced from the formulations with up to 4% feldspar and those produced with up to 8% feldspar and residue permitted a reduction in the water absorption rate and an increase in the mechanical resistance while those samples produced with up to 4% residue had an increase in the mechanical resistance when compared to those produced from the basic mass and that the formulation with 2% feldspar and residue presented the best technological properties, lowering the sintering temperature down to 1120°C

Formulação de massas cerâmicas para porcelanas elétricas utilizando resíduos oriundos de corpos de fusíveis

The power industry generates as waste ceramic bodies of electrical fuses that are discarded after use. The formulation of ceramic bodies for porcelain electrical insulators using waste from the bodies fuse allocation promotes environmentally appropriate, through the reuse of the material. This work evaluated the technical feasibility of using waste for use in electrical porcelains with formulations containing the residue, feldspar and kaolinite. The raw materials were processed through grinding and sieving to 200 mesh. The ceramic material obtained from the proposed formulations with 25%, 30%, 34% and 40% of the residue went through a vibratory mill for grinding and homogenization, and then were sieved at 325 mesh. The samples were shaped in a uniaxial press, with the application of 25 MPa and sintered at 1100° C, 1150°C, 1200°C, 1225°C and 1250°C, at levels of 20 and 45 minutes. Were also developed bodies of evidence with reference formulations obtained without residue, to establish a comparison on physical, mechanical and electrical. The tests were conducted and technology: linear shrinkage, porosity, water absorption, resistance to bending to three points, measuring insulation resistance electrical resistivity of the material, X-ray diffraction and X-ray fluorescence Waste characterizations pointed to the existence of two phases: mullite and quartz phases are of great importance in the microstructure of the ceramic and this fact reveals a possibility for reuse in electrical porcelains. The mullite is an important constituent because it is a phase that makes it possible to increase the mechanical strength in addition to the body allows the use at high temperatures. The use of ceramic bodies residue fuses, proved feasible for application in electrical porcelain and the most significant results were obtained by the formulations with 25% waste and sintering at 1200°C

Efeito da natação e do basquetebol em cadeira de rodas sobre o colesterol HDL: uma investigação em indivíduos com lesão medular

Despite the observation of an increase in life expectancy in individuals with Spinal cord injury (SCI), it is lower than that of the general population. Studies have shown that affected individuals have a sedentary lifestyle that reflects negatively on health and quality of life. Studies have demonstrated that HDL cholesterol (HDL-C) levels, a high-density lipoprotein and important predictor of cardiovascular disease, are lower in this population exposing these people to a greater incidence of heart disease from atherosclerotic process In the general population, exercise increases HDL-C serum levels, but this phenomenon is not very clear in people with spinal cord injury (SCI). The present study examined the effect of both swimming and wheelchair basketball in the lipid profile of eleven men and seven women with SCI. The subjects included in regular exercise programs showed increases in HDL-C levels and decreases in CT/HDL-C and LDL-C/HDL-C ratios. We found better results mainly in men with lower levels of SCI and in those that sustained exercise intensities above 60% of the heart rate reserve. The duration of training sessions can be an essential factor in these results. The results suggest that both the exercise prescription and the personal characteristics of people with SCI influence changes in the lipid profile mediated through exercise. The elaboration of this work is an attempt to clarify uncertainties about health and the longevity of people with SCI generated in discussion of all members of the interdisciplinary rehabilitation team, especially the physiotherapists, nutritionists, nurses and physicians that contributed considerably in all phases of the research

Seleção de categorias da Classificação Internacional de Funcionalidade, Incapacidade e Saúde para avaliação do paciente com acidente vascular cerebral em reabilitação

Stroke represents the first cause of disabilities among adults. Although different professions work together in treatment of stroke patients, all they use different terminologies for the description of the patients problems and it can constitute an impediment in the communication between the staff members. Thus, the multidisciplinary and interdisciplinary work would be facilitated if using a reference common tool, as the new International Classification of Functioning, Disability and Health (ICF). However, the ICF is very extensive and complex and due to its complexity, it has been evidenced the necessity to select its categories to become it more practical. The aim of the study was to investigate which categories of the ICF are more suitable to evaluate and to describe the stroke patient in the view of teachers and municipal public health professionals. It was a descriptive research, which involved 5 professors and 11 professionals of Physiotherapy that have worked at the health public area in Natal / RN. It was used the Delphi Technique in 3 rounds and the Likert Scale to select the categories among the ICF components. As result, from the 362 IFC categories, 94 were selected. The selected categories correspond to rehabilitative characteristics of Stroke patients in the universe of the Physiotherapy performance. The methodology applied was suitable to the studied object emphasizing the necessity of future studies for validation of the chosen categories

Alterações no metabolismo de zinco relacionadas ao envelhecimento

Although many studies point to alterations in the organic concentrations of zinc in elderly patients, the mechanisms by which aging might cause changes in the metabolism of this nutrient remain unclear. Thus, we assessed the changes in plasma zinc, Zinc Binding Capacity to Plasma Protein (ZnBCPP) and Saturation Index (SI), comparing elderly individuals and young adults. The zinc analyses were performed by atomic absorption spectrophotometry. A statistically significant difference (p < 0.001) was found between the two groups, in relation to plasma zinc and SI, but the ZnBCPP did not differ between the younger and older subjects. In agreement with this result, it was shown in the young group that 76% (R2 = 0.760) of the ZnBCPP variations are explained by the variations in plasma zinc and SI. In the elderly group this measure decreased to 30.5% (R2 = 0.305). We conclude, therefore, that aging may be a factor associated to changes in control mechanisms and in zinc homeostasis, and could even alter ZnBCPP response patterns and other zinc-related indicators of nutritional status.

Atrás das grades: redes sociais, habitus e interação social no sistema carcerário do RN

Esta tesis trata de discutir y entender los diversos tipos de redes sociales y formas de interacción social presentes en el sistema penitenciario de Rio Grande do Norte. Nuestro problema se basa en un incremento significativo en las tasas de encarcelamiento y la prisión en Brasil y el mundo en los últimos diez años. Asimismo, la aparición del crimen organizado ya, en cierta medida, el control de las prisiones brasileñas, como el Comando Vermelho (CV) y el Primeiro Comando da Capital (PCC), una consecuencia directa de las terribles condiciones de las prisiones de Brasil y aumento de la violencia y el crimen en nuestro país. Para resolver el problema, se optó por utilizar las categorías de análisis de Michel Foucault (prisión y la disciplina), Pierre Bourdieu (habitus y campo), Ervirng Goffman (institución total, de interacción, de fachada y de equipo) y Mark Granovetter, Ricardo Abramovay e João Peixoto, entre otros, la nueva sociología económica (Redes, nodos y lazos) como principal apoyo. También construyó una revisión histórica de la cárcel en Brasil y Rio Grande do Norte hasta llegar al objeto. Esto, en términos de investigación cualitativa, se sumergió en el mundo de las prisiones Dr. Francisco Nogueira Fernandes, conocido como Penitenciario de Alcaçuz, ubicado en el municipio de Nísia Bosque, Rio Grande do Norte. Penitenciaría del Estado de origen, las casas de Alcaçuz seiscientos cuarenta y tres reclusos, divididos en cinco pabellones, un total de ciento cuarenta y siete células. Mediante la observación sistemática y la entrevista cualitativa s semi-estructurada como las principales fuentes de recopilación de datos, hemos tratado de explicar el universo que acabamos de analizar por las Ciencias Sociales. Nos dimos cuenta de que, para cumplir con la escena nacional, regaliz viola de manera flagrante lo que se denomina en la Constitución de 1988 y LEP (Ley de Ejecución Penal), sin tener en cuenta los derechos de los individuos a una porción de una oración con un mínimo de dignidad. Se ha demostrado que las personas que permean el universo proviene de un ambiente de la prisión, la sociabilidad violenta, sedo también tienen un habitus precario. La prisión, espacio disciplinario y un tipo específico de interacción social marcada por el control, contribuye a la profundización de habitus, pero que muestra que no es también como un espacio cerrado en absoluto, sino un lugar donde penetran las redes y dinámicas muy social. Al mismo tiempo, se encontró que más de la presencia de "grupos organizados" es el espacio en las cárceles para la interacción social y las redes sociales que pasan dentro y fuera de su espacio
