Redução do imposto sobre produtos industrializados: uma análise econômico-tributária dos reais efeitos das medidas de incentivo ao mercado automotivo

Aborda-se as medidas de redução da alíquota do Imposto sobre Produtos Industrializados para o mercado automotivo, como instrumento extrafiscal de incentivo ao setor em questão, diante dos efeitos da crise econômica mundial de 2008. O estudo efetuado tem como objetivo verificar os reais efeitos econômico-tributários da redução do IPI para o setor automotivo, verificando se as vendas, de fato, aumentaram com os programas de incentivo, assim como em que medida o consumidor final foi beneficiado pela desoneração tributária concedida pelo Governo. Como forma de viabilizar o estudo proposto, serão analisados os diferentes programas de incentivo ao setor automobilístico, levando em consideração seus períodos de vigência e evolução das alíquotas no decorrer do tempo. Nesse sentido, demonstra-se necessário analisar a progressão das vendas no período analisado, assim como a evolução dos preços dos automóveis objetos do benefício fiscal. Conforme se verificará, as medidas de redução do IPI proporcionaram a recuperação do setor automotivo, com um considerável aumento nas vendas, além de terem beneficiado o consumidor final, com uma significativa redução do preço de mercado dos automóveis.

O referencial para a análise da adequação será os princípios constitucionais regentes das medidas cautelares pessoais, notadamente o da presunção de inocência e da proporcionalidade.

Medidas de risco extraídas de opções sobre petróleo

Bali, Cakici e Chabi-Yo (2011) introduziram uma nova medida de risco, englobando as medidas de risco de Aumann e Serrano (2008) e Foster e Hart (2009). Trata-se de um modelo de medida de risco implícito de opções baseado na distribuição neutra ao risco dos retornos de ativos financeiros. Este trabalho se propõe a calcular a medida de risco de Bali, Cakici e Chabi-Yo (2011) com base nas opções de petróleo, a commodity mais importante da economia mundial. Como os preços das opções incorporam a expectativa do mercado, a medida de risco calculada é considerada forward-looking. Desta forma, esse trabalho também analisa a significância dessa medida em prever a atividade econômica futura. Os resultados indicaram poder preditivo em relação ao índice VIX, o qual representa a incerteza do mercado financeiro, e ao índice CFNAI, indicador da atividade econômica norte-americana.

Simulação computacional de medidas estereológicas em estruturas de metal duro (WC-Co)

This work focuses on the creation and applications of a dynamic simulation software in order to study the hard metal structure (WC-Co). The technological ground used to increase the GPU hardware capacity was Geforce 9600 GT along with the PhysX chip created to make games more realistic. The software simulates the three-dimensional carbide structure to the shape of a cubic box where tungsten carbide (WC) are modeled as triangular prisms and truncated triangular prisms. The program was proven effective regarding checking testes, ranging from calculations of parameter measures such as the capacity to increase the number of particles simulated dynamically. It was possible to make an investigation of both the mean parameters and distributions stereological parameters used to characterize the carbide structure through cutting plans. Grounded on the cutting plans concerning the analyzed structures, we have investigated the linear intercepts, the intercepts to the area, and the perimeter section of the intercepted grains as well as the binder phase to the structure by calculating the mean value and distribution of the free path. As literature shows almost consensually that the distribution of the linear intercepts is lognormal, this suggests that the grain distribution is also lognormal. Thus, a routine was developed regarding the program which made possible a more detailed research on this issue. We have observed that it is possible, under certain values for the parameters which define the shape and size of the Prismatic grain to find out the distribution to the linear intercepts that approach the lognormal shape. Regarding a number of developed simulations, we have observed that the distribution curves of the linear and area intercepts as well as the perimeter section are consistent with studies on static computer simulation to these parameters.

Avaliação ambiental de manguezais adjacentes aos campos petrolíferos de Macau e Serra (RN), como subsídio às medidas mitigadoras ao processo erosivo

Among the various effects caused by the climate change and human intervention, the mangrove ecosystem changes through of the years has been worth mentioning, which hasn t known which are the pros and cons for the adjacent coastal and estuarine environments yet. It happens due to the present dynamism in these areas, besides of the difficult understanding of the processes associated with evolution. This study aimed to environmentally evaluate adjacent mangroves from the Macau and Serra oil fields, located on Rio Grande do Norte northern coast, to support the mitigating actions related to the containment of the erosive process, as well as, according to the principles of the Clean Development Mechanism (CDM), to assess the amount of atmospheric carbon sequestered by the studied ecosystem. An inventory was conducted through mangrouve mapping which has supplied this research, especially regarding to the structural characterization of mangrove areas. To understand the local mangrove behavior in a greater level detail, techniques of remote sensing, GIS and GPS were used to make an analogy between the current and past states of the mangrove studied, allowing to make anticipated projections for the future impacts or changes in that region. This study combined data from multispectral LANDSAT 5 TM, Landsat 7 ETM+ with radar microwave data from SAR RADARSAT-1, which increased the interpretation capacity of the data from optical sensor systems. The interpretations have been supported by the data field, representing a better and innovative methodology for the environmental and taxonomic characterization of mangrove forests considered. The results reveal that mangroves of the Ponta do Tubarão Sustainable Development Reserve are biologically representative areas and providing a variety of benefits, especially for local communities, constituting the priority sites for actions development aimed at conservation. They also have been showing the necessity to make mitigating measures in order to recover degraded areas through reforestation or creating new areas of mangrove, as currently 7.1% of the mangrove forests studied are dead or in an advanced state of decomposition. The amount of atmospheric carbon sequestered proved very significant when analyzed for the whole area, which is able to sequester atmospheric 4,294,458 Ton CO2 per year

A aplicação do acordo sobre subsídios e medidas compensatórias pelo estado brasileiro

The Multilateral Trading System has evolved and presented new international mandatory rules to States. Along with the World Trade Organization constitutive treaty, Brazil has incorporated the Agreement on Subsidies and Countervailing Measures (ASCM) in the national legal system. That treaty limits de scope of subsidies concession by governments since this practice can constitute a mechanism of commercial disloyalty, affecting national industrial development in the importing country. At the same time, the multilateral agreement grants defense legitimate instruments to States, among them the possibility of domestically and unilaterally imposing countervailing measures to subsidized products that enter the national territory. Since the issue concerns both international and domestic level in complementary grounds, this research, besides investigating the treaty related obligation, aims at studying the national legal fundaments to ASCM s application by the Brazilian State. Therefore, the essential point resides in the State s conduction of its international trading and also in its available and constitutionally established mechanisms of economic intervention. State s regulating power reveals itself as a fundamental prerogative to succeed in the internalization of international agreement s requirements in the domestic legal system, which represents a basic prerequisite to the implementation of countervailing measures. Once the whole normative outlines are apprehended, this study shall scan the administrative process of trading defense main elements, along with the means of controlling public administration acts. The action taken by the public organs that directly intervene in foreign trade shall be analyzed as well, so as to enable reasoning if the unilateral application of countervailing duties by the Brazilian State is happening on legitimacy grounds

A teoria de Dienes no ensino de transformação de medidas de comprimento, área e volume no curso de pedagogia

The study was aimed to test a teaching module on the Zoltan Paul Dienes theory, focusing on the content: The transformation of measurements: length, areas and volumes. The study based on constructivist theory consisted in a methodological intervention with students of the 7th period of the Course of Pedagogy, in Central Campus, Federal University of Rio Grande do Norte (UFRN). A preliminary study with 40 students called diagnostic evaluation found that students did not understand the concept of measurements transformation and its processing steps. The latter was performed only with the help of the table of measurements transformation with no understanding of the content. He applied a pretest, a set of activities and a post-test. The latter was used as a tool for evaluation of the student learning process. The answers of these ones were evaluated according to the concept of reflective abstraction of Jean Piaget, one of the authors who influenced the Dienes theory

Utilização de medidas biométricas para predizer características da carcaça de cabritos Saanen

Foram determinadas medidas biométricas de caprinos leiteiros com o objetivo de estimar equações que permitam predizer o peso e as características da carcaça de animais sob diferentes condições nutricionais. Realizou-se um experimento em duas fases, utilizando-se 27 cabritos machos da raça Saanen em cada uma, distribuídos nos tratamentos: alimentação à vontade, 30 e 60% de restrição. O peso vivo (PV) inicial foi de 5 kg na Fase 1 e 20 kg na Fase 2, abatendo-se os animais ao atingirem 20 e 35 kg de PV, respectivamente. Foram determinadas as medidas biométricas e avaliada a condição corporal no animal vivo e, após o abate e resfriamento de 24 horas, as medidas da carcaça. Estimaram-se o peso em jejum (PJ), o peso da carcaça fria (PCF) e a compacidade da carcaça, em função das medidas biométricas. O perímetro torácico e o comprimento corporal foram as medidas biométricas que apresentaram melhor ajuste para estimar o PJ, o PCF e a compacidade da carcaça e, por isso, são recomendados, por serem precisos, práticos e de fácil execução.

Desenvolvimento e validação de protótipo das medidas de desenvolvimento humano

To mesure the human performance is a challenge, mainly due to the multidimensional factor movement. Instruments, mostly only assess one dimension of it. Objective: To develop a prototype capable of measuring the skills of human performance and check its validity using method comparison approach. Methods: The study was divided into two stages. The first Prototype was developed and tested simultaneously with an instrument to study the Rectilinear Uniform Motion and Uniformly Miscellaneous. In the second phase the sample consisted of Paralympic basketball athletes (n=09) and karate athletes (n=31) and all agreed to the terms of participation in the research. The evaluation of performance measures was performed with the prototype, the results obtained were compared with the data calculated by a statistical package is used as a reference. Results: All variables calculated by the prototype showed no significant differences when compared with the results calculated by the reference instrument and statistical package. Conclusion: The prototype has been developed and the results obtained in laboratory and field indicate that the prototype can be used for measuring human performance measures, with immediate results without the need for a conventional computer return, provided they fulfill the criteria described

Correlações genéticas entre escores visuais e características de carcaça medidas por ultrassom em bovinos de corte

O objetivo deste trabalho foi estimar correlações genéticas e fenotípicas entre escores visuais e características de carcaça medidas por ultrassom, para verificar a eficácia desses escores na determinação da musculosidade e na avaliação da carcaça. As características de carcaça medidas por ultrassom foram área de olho de lombo (AOL) e espessura de gordura subcutânea (EG), mensuradas entre a região da 12ª e 13ª costelas, bem como a espessura de gordura subcutânea na garupa (EGP8). As características de estrutura (E), precocidade (P) e musculosidade (M) foram avaliadas por meio de escores visuais. Os componentes de covariância usados para estimar as correlações genéticas e fenotípicas foram obtidos pelo método da máxima verossimilhança restrita, em uma análise multicaracterística. As estimativas de correlações genéticas entre AOL e E, P e M foram 0,54, 0,58 e 0,61, respectivamente, e indicaram que, a longo prazo, a utilização da AOL como critério de seleção poderá produzir animais com maiores escores visuais para essas características. As correlações genéticas estimadas entre as espessuras de gordura (EG e EGP8) e os escores P e M apresentaram comportamento semelhante. Entretanto, as correlações genéticas entre as espessuras de gordura (EG e EGP8) e E foram próximas de zero. As correlações fenotípicas seguiram as mesmas tendências das respectivas correlações genéticas. Essas estimativas indicam que os escores visuais são determinados, em parte, pelos mesmos conjuntos de genes que influenciam a AOL.

Análise das medidas de boa e má diversidade na construção de comitês de classificadores através de metaheurísticas de otimização multiobjetivo

Committees of classifiers may be used to improve the accuracy of classification systems, in other words, different classifiers used to solve the same problem can be combined for creating a system of greater accuracy, called committees of classifiers. To that this to succeed is necessary that the classifiers make mistakes on different objects of the problem so that the errors of a classifier are ignored by the others correct classifiers when applying the method of combination of the committee. The characteristic of classifiers of err on different objects is called diversity. However, most measures of diversity could not describe this importance. Recently, were proposed two measures of the diversity (good and bad diversity) with the aim of helping to generate more accurate committees. This paper performs an experimental analysis of these measures applied directly on the building of the committees of classifiers. The method of construction adopted is modeled as a search problem by the set of characteristics of the databases of the problem and the best set of committee members in order to find the committee of classifiers to produce the most accurate classification. This problem is solved by metaheuristic optimization techniques, in their mono and multi-objective versions. Analyzes are performed to verify if use or add the measures of good diversity and bad diversity in the optimization objectives creates more accurate committees. Thus, the contribution of this study is to determine whether the measures of good diversity and bad diversity can be used in mono-objective and multi-objective optimization techniques as optimization objectives for building committees of classifiers more accurate than those built by the same process, but using only the accuracy classification as objective of optimization
