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.

We examine the drivers behind the establishment mode choice of German multinational enterprises (MNEs) in the sectors of Automotive, Chemicals and Mechanical Engineering in Brazil for the years 1993-2013 using a novel sample of primary data obtained directly from German MNEs. Based on prevalent theories found in the literature, we test the most common hypotheses on our sample. Firms with high R&D activities and firms with prior market knowledge in Brazil in from of previous sales offices are more likely to enter Brazil by a Greenfield investment. We also show that it is the specific private ownership of the German so-called hidden champions that drive those specific SMEs to enter Brazil by Greenfield, a sneaking suspicion that has been made before. Finally, we show that the establishment mode choice between Brazil and the USA only deviates to a low extent, with German MNEs preferring to enter Brazil by Greenfield and the USA by M&A. Thereby, we provide valuable insights for future research in this field.

O setor automotivo é bastante representativo na economia nacional, o que motivou a realização deste estudo sobre a demanda por veículos novos no Brasil. No presente trabalho, é abordado um modelo econométrico que permite calcular as elasticidades do preço, da renda e do crédito em relação à demanda por veículos, sob a luz da teoria da cointegração. Analisando-se o período de junho de 2000 a janeiro de 2014, verifica-se a ocorrência de três quebras estruturais. Estas quebras dividem o intervalo de tempo analisado em quatro subperíodos, cada um com uma dinâmica própria. A constatação deste fato, muitas vezes negligenciado na literatura científica prévia, é um dos principais resultados deste trabalho: afinal, conclusões bastante distintas seriam obtidas ao se considerar o período todo sem quebras. Vale também destacar que o crédito se mostrou relevante para a demanda em todos os subperíodos: acredita-se, portanto, ser efetiva a implementação de uma política de estímulo ao setor, por meio do incentivo ao crédito. Por último, comenta-se que, no passado recente, a cada 1% de redução no preço do automóvel, a demanda aumentou numa proporção 30% maior. Este resultado corrobora com a percepção de que a redução de impostos pode alavancar a venda de veículos.

A crise financeira internacional de 2008 afetou tanto a economia dos Estados Unidos quanto a economia mundial. Assim, discutiu-se as origens da crise do “subprime”, em uma contextualização histórica e entendeu-se a repercussão dessa crise, com foco nas medidas anticíclicas brasileiras adotadas em nível setorial. Através de estudos econométricos que visavam avaliar a eficácia dessas medidas de políticas fiscal, monetária e creditícia, direcionadas aos setores automotivo, de construção civil e de móveis e eletrodomésticos, buscou-se entender a eficácia das medidas anticíclicas tanto como incentivo econômico, quanto na manutenção do nível de emprego, dois dos principais focos das políticas anticíclicas brasileiras. A análise empírica revelou, no lado do incentivo dos setores, que a política monetária expansionista não teve o efeito esperado em nenhum dos três setores testados, enquanto que as políticas creditícia e fiscal, também expansionistas, tiveram efeitos positivos sobre os setores em estudo. Pelo lado da eficácia na manutenção do emprego, as políticas fiscal e monetária foram eficazes para os três setores analisados, o que nos permite concluir que as medidas do governo tiveram alguma forma de eficácia. É importante ressaltar que se assumiu a premissa para as séries de IPI sobre o setor de móveis e eletrodomésticos e a série de desemprego, que não estavam disponíveis de forma específica, constituindo uma limitação ao trabalho.

Droughts surfaced in 1877 as a crucial problem for the birthing Brazilian nation. Engineers, who formed the country's technical and scientific elite, took it upon themselves to study, understand and fight the problem through planned actions of intervention on space. This work, based on proposals and discussions contained in engineering magazines and reports, aims to provide elements for the comprehension of how these systematized actions against droughts, in the Iate nineteenth and early twentieth century, contributed to spatial analysis and the formation of a (then-inexistent) regional and territorial planning discipline in Brazi!. Engineers, by taking up the position of masterminds in the country's modernization, guaranteed for themselves personal economic stability, social prestige and political power. By understanding nature, either as a resource to be exploited or an adversary to national progress, they contributed to the delimitation of the region now known as the Northeast. By seeking to understand the drought phenomenon, they created knowledge about the space they sought to intervene on; by constructing their projects amid political and economical difficulty, they changed the organizational structures of cities and country in the northeast. The proposals for açudes (Iarge water reservoirs) allowed the fixation of population and the resistance against droughts; the roads - railroads and automotive roadways - connected the sertão to the capitais and the coast, speeding up help to the affected populations during droughts and allowing the circulation of goods so as to strengthen the local economies in normal rimes. The adopted practices and techniques, adapted from foreign experience and developed through trial and improvement, were consolidated as an eminently spatial intervention course, even if a theoretical body of regional or territorial planning wasn't formed in Brazil. Regional Planning proper was first applied in the country in the Northeast itself, in the 1950s, based off an economical view of reality in order to achieve development. The engineer's work prior tothat date, however, cannot be dlsconsldered. It was proved that, despite facing financial and political hurdles, engineers had a profound commitment to the problem and intended to act systematically to transform the economical and social relations in the region, in order to be victorious in their struggle against droughts

Efforts in research and development of new technologies to reduce emission levels of pollutant gases in the atmosphere has intensified in the last decades. In this context, it can be highlighted the modern systems of electronic engine management, new automotive catalysts and the use of renewable fuels which contributes to reduce the environmental impact. The purpose of this study was a comparative analysis of gas emissions from a automotive vehicle, operating with different fuels: natural gas, AEHC or gasoline. To execute the experimental tests, a flex vehicle was installed on a chassis dynamometer equipped with a gas analyzer and other complementary accessories according to the standard guidelines of emission and security procedures. Tests were performed according to NBR 6601 and NBR 7024, which define the urban and road driving cycle, respectively. Besides the analysis of exhaust gases in the discharge tube, before and after the catalyst, using the suction probe of the gas analyzer to simulate the vehicle in urban and road traffic, were performed tests of fuel characterization. Final results were conclusive in indicating leaded gasoline as the fuel which most contributed with pollutant emissions in atmosphere and the usual gasoline being the fuel which less contributed with pollutant emissions in atmosphere

Brazil is the only country in South America to have an automotive supplier sector based on natural fibers. New opportunities are arising due to an increase demand by the car makers in applying natural fibers in their parts. Several crop fibers have been developed in Brazil. Among them can be listed caroa, piacava, pupunha, mutum and others of regional application. For the automotive industry, which requires large quantities with uniform quality, the alternatives are sisal (170,000 ton/yr), curaua (150 ton/yr in 2003), malva, 200 ton/yr; Brazil is the single largest producer country of sisal, and commercially, the only one in curaua. For South America, the alternatives are fique in Colombia, abaca in equator, flax in Argentina and curaua in Venezuela. It must be understood by the target countries of drugs, is that crop fiber can be an economic alternative to coca in the Andes region, therefore an instrument of land reform and drug reduction plantations. Several companies have a strong program of apply natural fibers based components in their products: Volkswagen do Brazil, DaimlerChrysler, General Motors do Brazil. Among their suppliers can be listed companies such Pematec (curaua), Toro (sisal, coir and jute), Incomer (sisal and jute), Ober (jute, curaua), Indaru (jute and sisal), Antolin (imported kenaf,) Tapetes Sao Carlos (sisal), Poematec (coir) and Art-Gore, with Woodstock'' wood and natural fibers). Figures about production and demand are discussed in the paper.

As can be inferred by the title of its study The constitutional principle of sustainable development and the utilization of hidrical resources in the oil industry the transcribed pages are dedicated to the approach of the mentioned subjects which, despite being apparently different, will be shown intrinsically connected as goes by the study. The superation of this first step by the reader will lead to an important perception of the title: that the situation requires, urgently, a defined posture, a complete conduct change and, therefore, a modification of the paradigms currently establisheds. To brake barriers, modifying what is lived by, is the ultimate goal. For that, there is no unique path, linear, but there were broached the development themes, the hidrical resources theme and oil and natural gas industry at the necessary points to achieve, by the end, a comprehension for the Brazilian Federal Republic goals in the search for the application of these juridical norms. The ones whom lay down over this study shall notice that, more than a simple approach over these themes (which are still less worked and searched in Brazil), the heavy critic of an instituted and pacifically accepted reality, directly offensive of the constitutional principles. The debate evolves from punctual and specific aspects, it gains life, flies, searching how the juridical order equalizes the economic model to the environment defense. Standing by the possibility of conciliation among constitutional principles, the remodeling of an economic segment is defended, aligning it to the sustainable limits. Development, sustainable, becomes means and goals to the implementation of liberty, capacitating everyone to achieve their goals of life, their libertments, fruit of the inherent antagonism of the Constitution the sustainable development offers, while an axiological vector, a new reality to the economic order, turning it into a motriz element to the fortification of constitutional normative force and for the national development

This paper aims to conduct a study to evaluate and measure the possible impact that the unavailability of spare parts can have on customer satisfaction for car dealerships in the post-sales. A theoretical-conceptual review on the subject of satisfaction and loyalty, on the backdrop of the reality of the automobile market, allowed the construction of a research tool dedicated to collect opinions of car owners, to allow an analysis empirical relationship between the availability of parts, repairs or scheduled service possible, and change or stay on the mark on the occasion of change of vehicle. 236 forms were applied to car owners in the city of Natal / RN. The results obtained in this survey allowed the identification of the unavailability of parts as a significant factor, among others, the motivation for the customer to switch brands. Collaterally, we could also conclude that the dynamics of change in marks, whatever its motivation, is reflected in the perceived positions of the different brands as the market share both in strictly quantitative terms and in terms of relative positioning, with significant changes in the ranking of consumer preferences for different brands available

The study aims identify the existence of quality culture in Brazilian automotive dealerships with ISO 9001, motivated by this research problem: exist a quality culture in this dealerships, which facilitates the adoption of quality practices supported by ISO 9001? For referencing, the theoretical review was written in five themes: organizational culture, quality culture, total quality management, ISO 9001 quality management system and the Brazilian automobile industry. As regards the methodological aspects, the research has an applied nature, with a quantitative approach, being exploratory in their objectives, and bibliographic, documental and survey as technical procedures. The organizations participating in the study were all Brazilian automotive dealerships certified with ISO 9001. The research intended cover all the 80 active dealers with ISO 9001 certification identified by the Brazilian Committee for Quality (ABNT CB-25). The survey recorded participation of 32 companies (response rate 40%). The questionnaire was sent to seller managers, formatted into five sections: 1) introductory message 2) manager profile, 3) reasons for implementation and benefits generated by ISO 4) adoption levels of quality practices and 5) diagnosis of organizational culture. The questions contained in sections 2 and 3 were structured in multiple choice, and in the remaining sections were structured in Likert 5-point scale. The statistical method used (data analysis), was the descriptive statistics, for data representation in frequency percentage (FP) and standard level (SL). The results showed that the interviewed dealerships have an organizational culture with very high levels of prevalence in "outcome orientation" and "attention to detail" cultural dimensions. In addition, about the other two dimensions considered conducive to quality (innovation and teamwork/respect for people), both observed high prevalence. Based on the present results, concluded that the organizational culture of Brazilian dealerships with ISO 9001 are quality oriented, being conducive to adoption of quality practices supported by TQM Systems. However, it is important to mention that the quality culture identified is not sufficiently developed to adopt quality practices at optimal levels, which sets up an unfavorable scenario to deals with highly rigorous customer

Structures capable of absorbing large amounts of energy are of great interest, particularly for the automotive and aviation industries, to reduce tbe impact on passengers in the case of a collision. The energy absorption properties of composite materials structures can be tailored, thus making these structures an appealing option a substitute of more traditional structures in applications where energy absorption is crucial. ln this research, the influence of some parameters, which affect the energy absorption capacity of composite material tubes, was investigated. The tubes were fabricated by hand lay-up, using orthophthalic polyester resin and a plain weave E-glass fabric Test specimens were prepared and tested under compression load. The ínfluence of the following parameters on the specific energy absorption capacity of the tubes was studied: fiber configuration (0/90º or ± 45°), tube cross-section (circular or square), and processing conditions (with or without vacuum). The results indicated that circular cross-section tubes with fibers oriented at 0/90º presented the highest level of specific energy absorbed. Further, specimens from tubes fabricated under vacuum displayed higher energy absorption capacity, when compared with specimens from tubes fabricated without vacuum. Thus, it can be concluded that the fabrication process with vacuum produce composite structures with better energy absorption capacity
