O principal objetivo da dissertação é analisar os efeitos que a política cambial brasileira promoveu nas exportações F.O.B. de bauxita, alumínio primário, minério de ferro e caulim. Para tal, é desenvolvido um modelo econométrico, Modelo de ajustamento parcial de Nerlove, procurando avaliar os padrões de reação das exportações no curto e longo prazos. Os dados utilizados são trimestrais e cobrem o período de 1990 a 2003. As regressões foram estimadas através do método dos Mínimos Quadrados Ordinários (MQO). As variáveis elegidas como explicativas foram a taxa de câmbio real efetiva brasileira, a renda mundial, a capacidade produtiva da indústria brasileira, o produto interno bruto da indústria brasileira e uma variável dummy (que capta a influência da lei Kandir). Os resultados das regressões mostram que: as exportações são relativamente sensíveis ao crescimento da economia brasileira e mundial; e, a taxa de câmbio real efetiva brasileira (proxy da política cambial) produziu efeitos importantes na evolução das exportações do setor mínero-metalúrgico paraense.

Vários estudos sobre o setor pesqueiro têm sido feitos na região amazônica, entretanto, a maior parte se concentra em regiões próximas à calha do rio do Amazonas e sua foz. Este trabalho foi voltado para caracterização da pesca no rio Purus, frota pesqueira comercial e do pescador em três municípios pesquisados nas margens desse rio, estimando, assim, a produção e a renda da frota pesqueira naquela região. Os resultados mostram que em Manoel Urbano (AC) predomina a pesca de lagos, enquanto que Sena Madureira (AC) os ambientes de pesca são mais diversificados, com registros de pesca em lagos, rios e igarapés. Em Boca do Acre (AM) prevalece a pesca no rio Purus, principalmente na área dos municípios de Pauiní e Lábrea. Quanto ao tipo de embarcação utilizada, em Manoel Urbano a pesca é praticada somente em canoas, sendo que um pequeno percentual corresponde a canoas sem motor, enquanto que em Sena Madureira a maioria dos pescadores pesca de canoas e alguns utilizam barco motor; já em Boca do Acre a pesca é praticada basicamente de barcos, sendo menor o número de canoas motorizadas. Em relação aos custos da viagem, a análise mostrou que os custos variáveis representam 63% da receita dos pescadores de canoa e 76% da receita total dos barcos de pesca. A análise também mostra que pescadores de canoa motorizada apresentaram maior capacidade produtiva por unidade de esforço em relação aos pescadores de barcos.

The application of conservation practices in production systems is essential to the sustainability of the agricultural production capacity. The use of different cover crops can reduce the need of topdressing nitrogen fertilizers in wheat crops. This study aimed at evaluating the influence of cover crops residues (millet, sunn hemp, pigeon pea, millet + sunn hemp, millet + pigeon pea and fallow ground), grown previously to the summer crop (rice), and topdressing nitrogen doses (0 kg ha-1, 25 kg ha-1, 50 kg ha-1, 75 kg ha-1, 100 kg ha-1 and 125 kg ha-1), in the development and yield of wheat under no-tillage system. The experiment was carried out in Selvíria, Mato Grosso do Sul State, Brazil, in a Red Oxisol, in 2009/2010 and 2010/2011. The experimental design was randomized blocks, in a 6x6 factorial scheme. The cover crops developed during August/October (2009/2010) and September/November (2010/2011), previously to the summer crop, with the chemical desiccation performed respectively at 73 and 55 days after sowing. The wheat (winter) was sown in May, in both periods, and harvested at 113 (2009/2010) and 106 (2010/2011) days after emergence. The cover crops residues of pigeon pea, sunn hemp and millet + sunn hemp, preceding wheat, provided higher wheat yields, relatively to the fallow ground. The wheat yield showed a quadratic response to the increase in the nitrogen availability, reaching higher yields with the nitrogen doses estimated in 113 kg ha-1 (2010) and 98 kg ha-1 (2011).

The increase of the world population and their consumption power requires companies to increase their production capacity to meet demand. This production process is often performed without control and degrades the environment. In view of the stiffness of the legal requirements and the increasing of environmental concerns, companies need to act in a sustainable way to continue existing. The main objective of this study is to investigate how sustainability reports that follow the guidelines of the Global Reporting Initiative (GRI) can bring benefits to companies in the continuous improvement of its processes and the competitiveness of the sector. The sector chosen for the study was the automotive industry, due to its importance in the national economy and the significant impacts caused to the population and to the environment. The methodology consists of reading the GRI sustainability reports of companies and then performing a comparison among them and the bibliography of the subject. The results confirm the importance of the GRI sustainability reporting for companies and show how the selected indicators can contribute to the corporate management and to the control of its processes

This paper aims to survey data to analyze the productive capacity of a machining process of rolling bearings by methods-time measurement, in order to identify its bottlenecks and propose improvements in the system. The production times at the company are not known, the method of separation of operations and identification of its activities and the timing of production times and setup become points of departure for this paper. The results from this method of analysis provide clarity in identifying system weaknesses and by them it was possible to carry out the proposals for improvement in some process steps. The implementation of the improvements was not performed, but with the goals of this work was made possible to raise relevant information of the analyzed system

Work organized in shifts, either for technological, social or economic imposition, allows the best use of means of production, increasing the overall productivity of the enterprises. At the same time, this type of work harms the individual productive capacity of workers, particularly those involved in the night shift. The objective of this work was to assess the behaviour of production in a continuous line and subjected to work organized in shifts. Through the statistical method of analysis of variance, Spearman's test and Tukey's method, was analysed the distribution of the productivity index measured in three fixed shifts of work in a glass company. The productivity index, provided by the integrated management system of the company, refers to the ratio of actual productivity to total productivity. The statistical analysis shows that factors of production, such as allocation of workers, do not interfere with productivity, showing an unexpected pattern, where the average productivity for the three shifts are close and the correlation between the number of workers on the line and productivity is low. The conditions of production had an adverse work environment with exposure to noise, heat, vaporized mist of lubricating oil and risk of accidents. The findings show that the calculation of productivity in use is limited and its use in company’s production control may produce distortions. It is proposed to examine alternative calculations methods that consider the overall productivity

The no-tillage system is an important technique for maintaining and restoring the productive capacity of conventionally managed soils and degraded areas. The aim of this study was to evaluate the production of soy and maize grown on the straw of five cover crops and on spontaneous vegetation. The experiments were carried out in Votuporanga, in the state of Sao Paulo and in Selviria, in Mato Grosso do Sul, Brazil, in March 2008, after conventional soil preparation. The experimental design was of randomised blocks with four replications, using the following cover crops in different amounts of seed per hectare, to make up the treatments: Sorghum bicolor - 6, 7 and 8 kg ha(-1); Pennisetum americanum - 10, 15 and 20 kg ha(-1); Sorghum sudanense - 12, 15 and 18 kg ha(-1); S. bicolor and S. sudanense hybrid - 8, 9 and 10 kg ha(-1); and Urochloa ruziziensis - 8, 12 and 16 kg ha(-1). A control treatment with spontaneous vegetation was also used. After management of the cover crops, soy was planted in the first year of the study, and maize sown in the second, both under a no-tillage system. The dry matter accumulated by the different cover crops, and the agronomic characteristics of the soy and maize were all evaluated. It was concluded that the different cover plants proved to be good options for preceding the soy crop in Votuporanga, SP and the maize in Selviria, MS, and that the different amounts of seed used for each cover crop resulted in differences in relation to the agronomic characteristics of the crops of soy and maize.
