Os instrumentos de incentivo à produção e uso de biodiesel no Brasil: uma análise constitucional sob o princípio do desenvolvimento sustentável

The recent insertion of biodiesel derived from oily vegetables in the Brazilian energetic matrix calls for the study of some aspects that belong to it. The analysis of the carbonized energetic pattern concerns the paradigm of economic development that is constitutionally enshrined sustainable development which make environmental protection compatible with the needs of the economic rationality. This text is structured according to the ideas of modern hermeneutic that sees substantial value in the principles capable of create a harmonious relationship between law and society. The study of the constitutional principles to conduct a legal analysis about the National Program for Production and Use of Biodiesel - PNPB. The aim of the research is the study of PNPB ahead with the constitutional principles governing the economic order. To achieve this end we studied the sustainable development as a constitutional principle. We start with the notion that the thematic principles, and fundamental to understanding the dimension of sustainable development institute, since its concept is closely related to the applications of the principles enshrined in virtually all the constitutional order of the Western world. Then this was the National Energy Policy, initiating the approach by guiding principles of the National Energy Policy to develop the theme of public policy in the energy sector. Therefore, we studied the National Program of Biodiesel Production and Use - PNPB. From a technical introduction to the concept of biodiesel and a brief historical background, analyzing their advantages compared to fossil fuels predominantly used. Then it became a regulatory overview of the Brazilian legislation on the subject, central to understanding the plans and objectives pursued by the Brazilian government with encouraging the production of biodiesel. Finally discussed the tax incentives for production and use of biodiesel in Brazil. From the idea of federalism, characterized the tax as an instrument of state intervention in the economy. And finally it brought the tax incentives of Law No. 11.116/2005 in the face of the constitutional principles of economy and tax, and tax incentives from projects related to the Kyoto Protocol

Novas fronteiras petrolíferas no Brasil : uma análise da necessidade de nova regulamentação da área do pré-sal sob a ótica constitucional

The Oil industry in Brazil has gone through several stages during the economical, political and social historical process. However, the significative changes have happened in the last fifteen years, due to market opening arising from the relaxation of the state monopoly over the Oil deposits and its derivatives. The edition of the Constitutional Amendment #9, changing the first paragraph of the 177th item of the Federal Constitution, marked the end of a stiffness about the monopoly that the Brazilian state kept in relation to the exploration and research of Oil and Gas. The economical order was fundamental to actualize the idea contained in the #9 Amendment, since its contents has the power to set up measures to be adopted by public power in order to organize the economical relations from a social viewpoint. The new brazilian Oil scenery, called pre-salt, presents itself in a way to amaze the economical markets, in addition to creating a new perspective to the social sector. This work will identify, in this new scenario, the need for change in the legal system. Nevertheless, this subject must not be treated in a thoughtless way: being an exhaustible good, we shall not forget that the future generations also must benefit from the exploration of natural resources recently discovered. The settlement of a new regulatory mark, including the change in the concession contract model to production and sharing is one of the suggested solutions as a bill in the National Congress, in an attempt to ensure the sovereignty of the nation. The constitutionality of a new regulatory mark is questioned, starting from an analysis of the state monopoly, grounding the comprehnsions in the brazilian constitutions, the relevance of the creation of Petrobras for self-assertion of the state about the monopoly of Oil and derivatives, and its posture after the Constitutional Amendment nº 9 (1995), when a company stops having control of the state monopoly, beginning to compete in a fairly way with other companies. The market opening and private initiative are emphasized from the viewpoint of the Constitutional Principles of the Economical and Social Order. The relaxation of the monopoly regarding the exploratory activity in the Federal Constitution doesn't deprive from the Union the ownerships of underground goods, enabling to this federal entity to contract, directly or by concession of exploration of goods, to state-owned or private companies. The existing oil in the pre-salt layer transforms the scenario from very high risk to low risk, which gives the Union the possibility of defining another way of exploring this resources in the best interests of the Public Administration

A intervenção estatal no domínio econômico privado através da nova lei de recuperação de empresas e falências (lei 11.101/05)

Analysis of the elements of the Constitutional Order of the letter 1988 politics, with emphasis in the principles of this, a study on the intervention of the State in the private initiative by means of the Law of Recovery of Companies and Bankruptcies (law 11.101/05). New enterprise vision is admitted, over all in the interdependence between economic and social factors. Study on the globalization and the interdependence of economic and legal sciences in the construction of a legal optics in the search for the economic and social development, with the recognition of the interference of the Economy in the Right and its uneven importance. Still, we delineate the state intervention in the economic scope, of company and in the judicial recovery, as well as the consequences of such intervention in the involved credits in the judicial recovery and patrimony of the debtor in recovery. For such task, the elements of the Judicial Recovery, its principles and adequacy of these to the related ones in the chapter had been analyzed that turns on the national economic Order, describing the formal procedure for concession of the benefit of the Judicial Recovery and the principles in existing them. The forms of intervention of the State in the private economy were not disrespected, relating its direct and indirect performance as half of preservation of interests writings in the constitutional scope as public interest and preservation of the National economic Order. The regulating agencies as of direct state intervention were half not disrespected of the study for the relevance of the subject. It is revised national bibliography with incursions in French, Portuguese and North American comparative jurisprudence. One contributes in the aspect of the paper of the Judiciary Power in the protection of the companies in crisis and the social and economic impacts, over all in relation to the rights of the worked ones, credit and enterprise

Biomassa e desenvolvimento sustentável e sócio regional no Brasil: uma análise à luz da Constituição Federal de 1988

It is verified worldwide an increasing concern with the protection of natural resources in the planet, a fact that became relevant in Brazil since the promulgation of the Constitution of 1988, based on the viewpoint of sustainable development, which seeks to promote economic activities in the country according to the need for conservation and preservation of natural resources for the use of present and future generations. In addition, we seek to reduce the differences that occur in our society by determining as a fundamental objective to be persecuted by the Federative Republic of Brazil the reduction of social and regional inequalities. A value that should also be observed in the context of economic activities developed here, since it is a general principle of financial and economic order of the country. Therefore, considering the exhaustion of world s reserves of fossil fuels, as well as the impacts on the environment, especially for the large emission of greenhouse effect gases, the debate about the need to change the global energy matrix increases while alternative energy sources appears as a bet to fulfill the contemporary aspirations for sustainability, and Brazil emerges in a very favorable position, because it has the essential natural conditions to allow this sector s full development. In this perspective, the work has the scope to analyze how the production of alternative energy sources may act in the search for concretization of constitutional values, to promote sustainable development for present and future generations, and to reduce regional and social inequalities in an attempt to improve the quality of life of the population. It will also be observed the current regulatory framework of alternative energy sources in the national laws to verify the existence of legal and institutional security, which is necessary to guarantee the full development of the sector in the country. And to investigate the expected results, it will be observed through the concrete evaluation of specific practices adopted in the industry, analyzing their actual compliance with the constitutional provisions under analysis, based on the examination of the possibility of using renewable biomass sources for biofuel production, promoting development to the country, indicating the opening lines about how this important sector can act to solve the energy challenge today

Reconfigurações industriais das regiões metropolitanas do Nordeste: uma análise a partir do emprego formal

Industrial development experienced by Brazil from the 1950s, changed the concentration of population in the country. The process of development of domestic industry, concentrated in urban areas, crowded growing portion of the population.The Southeast region during the first stage of industrialization driven by the state, with the implementation of Plan goals, captained the major industrial projects implemented in the period and became the main industrial center of the country.In the decade from 1960 to 1980 the state action was marked by numerous regional development projects, softening the industrial concentration and Brazilian investment redirected to the Northeast.The second National Development Plan implemented in the 1970s led to major investments Northeast.This period marked the widespread urban growth and institutionalization of the first metropolitan areas in Brazil.The change of this developmental process is altered with the fiscal and financial crisis of the state in the 1980s and 1990s and spending cuts aimed at national development, reorienting the economy to liberal policies of economic liberalization and reduction of activity in the economy.Industrial policy was relegated to local development plans from the 1990s to the federating units fitting the wide use of tax incentives, the "war tax" to the continued industrialization process.In this context of the national economy work seeks to analyze the industrial setting in the metropolitan areas of Fortaleza, Recife and Salvador between 1995 and 2010.Although the metropolitan areas of Fortaleza, Recife and Salvador are the main urban centers of the Northeast, responsible for the advancement of industrial development, reconfigurations occurred between 1995 and 2010 by changing the level of industrial specialization built by regional division of labor in these regions.The work will be carried out by the method of descriptive analysis of the literature review on regional and urban development.Constitute quantitative method as the secondary data analysis of formal employment from the Annual Social Information (RAIS) Ministry of Labour and Employment (MTE).Using data RAIS / MTE analyzes the industrial specialization index using the Locational Quotient (LQ).Thus, it is assumed as a parameter analysis QL> 1, when the region has become specialized in a particular sector or QL <1, when the region does not have expertise in industrial sector analyzed.The conclusion of study indicates that there was in these metropolitan areas maintained the same bias hub.Fiscal policies, the states, was not successful in diversifying the productive structure and the Northeast region itself.This result is demonstrated by the need and dependence on state investments in the region to promote development.Industrial policies of recent years have been positive to meet the objectives of employment generation, but there must be specific policies for better diversification of production, in addition to integrating the economy of the Northeast sector and regionally

Crescimento econômico e restrição externa: evidências empíricas na economia brasileira (1991-2010)

This study aims to investigate the influence of the balance of payments constrained on economic growth in Brazil from 1991 to 2010. With this order, are shown some of the Keynesian balance of payments constrained growth models, inspired by Thirlwall (1979) and Kaldor (1970), which are supported by important points in common, such as adherence to the principle of effective demand. Given that within this theoretical perspective, there is no consensus about the best model to explain the growth rate allowed by the balance of payments constraint, the results are presented by the representative of the empirical literature that addresses the topic, which are necessary for understand the Brazilian case. From the estimation of the income elasticity of imports (0.85) via autoregressive vectors with error correction (VEC), it was calculated five growth rates of income, as predicted by the models of Thirlwall (1979), Thirlwall and Hussain (1982), Moreno-Brid (1998, 2003) and Lourenço et al. (2011) and compared with the actual growth rate. The empirical analysis has shown that: it can not reject the presence of external constraint in the Brazilian economy, there is a strong similarity in growth rates provided by different modeling suggest that growth with external constraint. In addition, when using data in quarterly for the period after 1990 there are no factors that could cause instability in the parameters of the import function (income elasticity and price elasticity of imports) within the period, which indicates that the structural break widely associated with the year 1994 was not confirmed by this study

Análise da contribuição de estagiários remunerados na força de trabalho em enfermagem

The present study analyses non obligatory and remunerated traineeships in nursing, as a contribution to work process in health and learning of students at nursing technician courses. It objectives to examine the contribution of medium level nursing students on scholarships at a teaching hospital s work force, at Natal/RN. It s a quantitative/qualitative, that uses descriptive statistics and analysis fulfilled with categories that emerged from research, through a dialog between the studied authors in the theoretical reference of nowadays work process, work force, non obligatory and remunerated traineeships, and night shifts. The collaborators of this research were 105 (73,43%) nursing technicians, medium level students on scholarships that fulfill remunerated traineeships at the hospital. The feminine gender was a major part of the collaborators, with 90 (85,70%), in which medium age was 29,71 years, 62 (59,00%) single, 57 (54,30%) don t have kids, 100 (95,23%) students on scholarships with complete medium level, 78,10% with professional experience before their insertion at the remunerated traineeships, 73 (69,50%) referred to enjoy the area, reason for the nursing technician course choice. About the technician course conclusion, 83 (79,00%) affirmed that happened between 2005 and 2008, and about traineeships time in the institution, 38 (36,20%) have between one and six months. About learning, 74 (70,50%) referred to learn with the nursing technicians and all fulfilled specialized courses, or grade up to bond with the school and be able to be trainees. These courses were considered low quality ones, what justifies the number of 54 (51,40%) students with scholarships that said their performance in studies is good and 75 (71,40%) are able to join it with the traineeships without problems. About remuneration as scholarship, 71 (67,60%) referred that helped to keep up with the studies, because this amount has specially this purpose, paying studies. About nonobligatory traineeships, the ABEn-RN affirmed that there s no following process to this traineeship mode, as long as there was never this concern, because obrigatory traineeships demand a lot of the efforts in the meetings. And COREN-RN doesn t supervise this way of contract. The present research observed that there is, in fact, a contribution of medium level nursing students on scholarships work force on the researched institution. Resigned to work circumstances established by the institution, representing the lack of human resources, materials, work conditions, and work insertion in night shifts, it s possible to affirm that the situation is irregular about the students on scholarships, besides the determinant risk factor to their lives and health. In addition to it, the students on scholarships, in order to maintain the quality of trainee in the institution, are obligated to fulfill courses to grade up, or specialized courses in nursing technician, at schools referred as bad quality ones

Enfermeiros pós-graduados: continuidades e rupturas no cotidiano profissional de hospitais universitários

A presente pesquisa teve como objetivo analisar as transformações do cotidiano profissional do enfermeiro do hospital universitário após a realização do curso de mestrado. Trata-se de um estudo com abordagem qualitativa, realizado no Complexo Hospitalar Universitário da UFRN, composto pelo Hospital Universitário Onofre Lopes (HUOL), Maternidade Escola Januário Cicco (MEJEC), e Hospital de Pediatria Professor Heriberto Ferreira Bezerra (HOSPED) localizados em Natal-RN; e pelo Hospital Universitário Ana Bezerra (HUAB) situado em Santa Cruz-RN. A população foi composta por vinte e dois enfermeiros, com título de mestre em enfermagem, que trabalham nessas instituições. Após encaminhamento e aprovação pelo Comitê de ética em pesquisa, conforme Parecer nº 268.498 e CAAE: 13922713.1.0000.5537, as entrevistas foram iniciadas, utilizando-se um roteiro semiestruturado, organizado em questões orientadas em conformidade com os objetivos do estudo. Do material empírico, emergiram as categorias que foram trabalhadas com base na análise de conteúdo temática, tendo como aporte teórico os estudos de Agnes Heller acerca do cotidiano e os de Paulo Freire sobre educação e mudanças, buscando a possível interlocução entre esses autores. Os resultados demonstram que o cotidiano dos enfermeiros nos hospitais universitários, após cursarem o mestrado, modifica-se a partir da própria motivação em cursálo e do apoio institucional recebido. As continuidades e rupturas apontadas estão distribuídas nas categorias: a inércia da cotidianidade, na qual os enfermeiros relatam a dificuldade em mudar seu cotidiano devido à rotina exaustiva e à falta de apoio; reconhecem mudanças particulares, compreendendo a formação de um olhar crítico/reflexivo/analítico, e a qualificação para o ensino e pesquisa; e as rupturas do cotidiano, que se referem às mudanças ocorridas no serviço, como a melhoria da assistência, pela implantação de resultados; e uma prática diferenciada por ter um profissional qualificado. Portanto, considera-se que a realização do mestrado contribuiu para o crescimento do intelectual e profissional do enfermeiro e, consequentemente, para o serviço, no cotidiano do Complexo Hospitalar Universitário, sendo reconhecido pelos enfermeiros o compromisso com uma maior responsabilidade social. Porém, ainda são necessárias reflexões sobre maneiras de minimizar as dificuldades apontadas, como forma de incentivar essa qualificação

Análise do balanço energético e da matriz de emissões de poluentes no Estado do Rio Grande do Norte

This thesis intends to show the level of pollutant emissions in the State of Rio Grande do Norte, generated by the final consumption of energy in the many different sectors of the economy. This information was obtained from the energetic matrix and from the pollutant emissions of the State and the data was taken from the Balanço Energético Estadual and from the Sistema de Informações Energéticas da Olade. The result will permit to identify the energy and most polluting economic sectors in Rio Grande do Norte, contributing to energy planning, giving direction to the public policy development that aim at the change of the energy matrix of the State. Also with the objective of reducing pollutant emissions through rationalization, efficiency and energy substitution, which the main objective is to promote the economic development based on energy consumption of less harmful impact on the environment, contributing to establishment of sustainable development

Sistema Híbrido de Inferência Baseado em Análise de Componentes Principais e Redes Neurais Artificiais Aplicado a Plantas de Processamento de Gás Natural

Nowadays, where the market competition requires products with better quality and a constant search for cost savings and a better use of raw materials, the research for more efficient control strategies becomes vital. In Natural Gas Processin Units (NGPUs), as in the most chemical processes, the quality control is accomplished through their products composition. However, the chemical composition analysis has a long measurement time, even when performed by instruments such as gas chromatographs. This fact hinders the development of control strategies to provide a better process yield. The natural gas processing is one of the most important activities in the petroleum industry. The main economic product of a NGPU is the liquefied petroleum gas (LPG). The LPG is ideally composed by propane and butane, however, in practice, its composition has some contaminants, such as ethane and pentane. In this work is proposed an inferential system using neural networks to estimate the ethane and pentane mole fractions in LPG and the propane mole fraction in residual gas. The goal is to provide the values of these estimated variables in every minute using a single multilayer neural network, making it possibly to apply inferential control techniques in order to monitor the LPG quality and to reduce the propane loss in the process. To develop this work a NGPU was simulated in HYSYS R software, composed by two distillation collumns: deethanizer and debutanizer. The inference is performed through the process variables of the PID controllers present in the instrumentation of these columns. To reduce the complexity of the inferential neural network is used the statistical technique of principal component analysis to decrease the number of network inputs, thus forming a hybrid inferential system. It is also proposed in this work a simple strategy to correct the inferential system in real-time, based on measurements of the chromatographs which may exist in process under study

Análise da viabilidade econômica de um sistema de aquecimento solar de água para uma empresa do setor hoteleiro

This paper presents an analysis of technical and financial feasibility of the use of a solar system for water heating in a fictitious hotel located in the Northeast region. Thereunto it is used techniques of solar collectors´ sizing and methods of financial mathematics, such as Net Present Value (NPV), Internal Rate of Return (IRR) and Payback. It will also be presented a sensitivity analysis to verify which are the factors that impact the viability of the solar heating. Comparative analysis will be used concerning three cities of distinct regions of Brazil: Curitiba, Belém and João Pessoa. The viability of using a solar heating system will be demonstrated to the whole Brazil, especially to the northeast region as it is the most viable for such an application of solar power because of its high levels of solar radiation. Among the cities examined for a future installation of solar heating systems for water heating in the hotel chain, João Pessoa was the one that has proved more viable.

Análise da bacia hidrográfica do Rio Punaú-Rio Grande do Norte utilizando ferramentas de geoprocessamento

Provide data and information on watershed becomes important since the knowledge of their physical characteristics, land use, etcetera, allows for better planning and sustainable use of economically, socially and environmentally in this area. The investigation of the physical environment has been commonly given with the use of geoprocessing, which has proved a very efficient tool. Within this context, this research aims at analyzing the river basin Punaú (located in the cities of Touros, Rio do Fogo and Pureza, state of Rio Grande do Norte) in several aspects, using geoprocessing as a tool of work, to provide information about the entire watershed. Specifically, this study aimed to update pre-existing maps, such as geological, geomorphological and land use, generating map of environmental vulnerability, under the aspect of erosion susceptibility of the area, generating map of legal incompatibility, identifying areas that are already being employed in breach of environmental legislation; propose solutions to the occupation of the river basin Punaú, focused on environmental planning. The methodology was based on the use of geoprocessing tools for data analysis and to make maps of legal incompatibility and environmental vulnerability. For the first map was taken into account the environmental legislation regarding the protection of watersheds. For the vulnerability analysis, the generated map was the result of crossing the maps of geology, geomorphology, soils and land use, having been assigned weights to different attributes of thematic maps, generating a map of environmental vulnerability in relation to susceptibility to erosion. The analysis results indicate that agriculture is the most significant activity in the basin, in total occupied area, which confers a high degree of environmental vulnerability in most of the basin, and some agricultural areas eventually develop in a manner inconsistent with Brazilian environmental legislation. It is proposed to consider deploying a measure of revitalization of the watershed in more critical areas and conservation through mitigation measures on the causes of environmental degradation, such as protection of water sources, protection and restoration of riparian vegetation, protection of permanent preservation areas, containment of erosion processes in general, and others listed or not in specific laws, and even the establishment of a committee of basins in the area

Governos locais e políticas de promoção econômica: uma análise da promoção econômica nos municípios brasileiros com população acima de 50 mil habitantes

This work aims to analyze the policy of economic promotion in the Brazilian cities of medium and great size (with population above of 50.000 hab.). The objective of the research is to launch light in the debate on the regional and municipal development, presenting the recent hypotheses supplied by literature. Of complementary form, had for specific objective presents the results of the Research of Basic Information of Cities - PIM, of Brazilian Institute of Geography and Statistics (IBGE), in two surveys carried through together to the Brazilian local governments (1999 and 2009). It analyzes the instruments of economic promotion used by local governments and the influence of the development variables, as the Local Human Index of Development (HID-L) and the Local Gross Domestic Product (GDP-L). The research sample that factors as HID-L and GDP-L has significant influence in economic promotion of cities and must be taken in account in the definition of the local strategies of development

Saúde psíquica e condições de trabalho dos profissionais de saúde nos hospitais da Universidade Federal do Rio Grande do Norte

A tese se propôs a avaliar a relação entre saúde psíquica e condições de trabalho em dois hospitais da Universidade Federal do Rio Grande do Norte, a saber: Hospital Universitário Onofre Lopes e Hospital Universitário Ana Bezerra. Adotou como ponto de partida epistemológico a abordagem psicossociológica, considerando que a compreensão sócio-histórica do contexto é indispensável para entender os fenômenos em análise. As condições de trabalho e a saúde psíquica foram abordadas interdisciplinarmente, fundamentando a construção de um modelo compreensivo de saúde psíquica que orientou a investigação. O caminho metodológico utilizado foi a pesquisação. Essa foi desenvolvida, utilizando técnicas como análise documental, observação participante, entrevistas não estruturadas, grupo focal e aplicação de um protocolo de pesquisa composto pelo questionário de condições de trabalho, pelo Questionário de Saúde Geral (QSG-60), pela Escala de Bem-Estar Afetivo no Trabalho (JAWS-12) e por questões sociodemográficas. A análise dos resultados mostrou que os escores sintomáticos de saúde psíquica variam por hospitais e que a saúde psíquica sofre influência das condições de trabalho, sobretudo em aspectos referentes a três dimensões: condições físicas e materiais; processos e características do trabalho e o ambiente sociogerencial. Em referência à primeira dessas dimensões, destacaram-se a exposição aos riscos psicobiológicos e de acidentes, bem como as exigências de esforço físico. Na segunda dimensão, a complexidade das atividades e a responsabilidade implicada nas mesmas. E, na última, os fatores de organização da atividade, violência e ambiente conflitivo. Como a relação do indivíduo com seu contexto é dialética, os resultados encontrados corroboraram que quanto mais as condições de trabalho são desfavoráveis, maior a afetação da saúde psíquica e dos afetos com relação ao trabalho, repercutindo novamente no ambiente de trabalho. Portanto, ações de melhoria das condições de trabalho precisam ser estabelecidas para resultar, no efeito inverso, proporcionando o aumento dos afetos positivos e a redução dos sintomas psíquicos

Análise dos conteúdos termodinâmicos em livros de Química e Física do ensino médio

PNLEM came out in 2004 and modified the view about schoolbook in Brazil. New perspectives pointed towards constitution of a more critical citizen as of an interdisciplinary and more contextualized teaching, made schoolbook understand these changes.But not always these alterations are checked up on by all means,because what we notice are adaptation of works have already known on market, where texts that are placed reveal environmental, socioeconomic, historical facts or daily phenomenon, or then scientific relevancy examples.We thus offer to analyse contents of chemical thermodynamics and physics for high school which are shown on schoolbook of chemistry and physics validated by PNLEM 2012, now called PNLD, studying the facts if these works bring these scientific sociocultural standpoint as well as their historical context,considering as analysis categories the following criteria: presentation of introduction, content contextualizing,presentation of concepts, thermodynamics historical context, representation in microscopic level and proposal of experiments.Eleven books were analysed,being five of chemistry and six of physics.So was applied a questionnaire with physics and chemistry teachers of high school to have an impression of their opinion about their teaching strategies and about schoolbook.This work grounded in orientations of legal documents about high school in Brazil (LDB,PCN,PCN+,OCEM) and in research on science teaching that regards specifically schoolbook and physics and chemical thermodynamics teaching.Were eleven books in number, only four denoted much coherence with new perspectives for high school, being two of chemistry and two of physics,whose concern about contextualizing and with a much integrated view of science to student s reality,indicating much social and critical character.The rest, when don t overlook,regard cultural and historical,socioeconomic contexts in isolated manner from presented concepts,aside from content
