O debate teve in?cio em finais da d?cada de 1980, contudo, recentemente a desacelera??o da ind?stria ganhou for?a nas discuss?es do meio acad?mico. Entre as principais teses nesse debate est? a novo-desenvolvimentistas que acredita na desindustrializa??o precoce causada principalmente pela sobreaprecia??o cambial. Contudo, parte da heterodoxia acredita que a desacelera??o da ind?stria esteja mais relacionada com a taxa de investimento do que do c?mbio. N?o obstante, segundo a tese ortodoxa, a perda de competitividade devido ao custo elevado de produ??o pode ter causada a desindustrializa??o no Brasil. Por outro lado, parte da ortodoxia n?o acredita que o pa?s esteja se desindustrializando, mas est? ocorrendo uma converg?ncia da ind?stria brasileira ? m?dia mundial. Assim, na tentativa de lan?ar luz sobre esse debate, o presente estudo busca identificar as raz?es da desacelera??o da ind?stria brasileira, enfatizando aspectos pouco explorados na literatura, e tentar definir se o pa?s padece ou n?o de um processo de desindustrializa??o. Ao analisar diversos indicadores, sobretudo, em n?vel de quantum, encontramos fortes ind?cios de que a desacelera??o da ind?stria brasileira pode ser caracterizada como uma desindustrializa??o, por?m ainda insuficiente para qualificar como precoce, dada a perda de participa??o da produ??o f?sica na produ??o total e o aumento da participa??o dos bens prim?rios na pauta de exporta??o / This study aims to contribute with evidence to reinforce or not the thesis of a possible deindustrialization of the Brazilian economy, with emphasis on period after 1995. The debate began in the late 80s, however, recently the industry deceleration gained strength in discussions academic. Between the main theses in this debate is the new-development that believes in precocious deindustrialization caused primarily by overvaluation exchange rate. However, part of heterodoxy believes the industry downturn is more related to the rate of investment than the exchange rate. Nevertheless, according to the orthodox thesis the loss of competitiveness due to the high cost of production may have caused the de-industrialization in Brazil. On the other hand, part of Orthodoxy does not believe that the country is deindustrializing it, but is occurring convergence of Brazilian industry the world average. Thus, in an attempt to shed light on this debate, this study intends to identify the reasons for the deceleration of the Brazilian industry, emphasizing aspects underexplored in the literature and define whether or not the country suffers a process of deindustrialization. When analyzing various indicators, especially the quantum level we find strong indications that the deceleration of the Brazilian industry can be characterized as a deindustrialization, though still insufficient to qualify as precocious, given the loss of share in physical production in total output and the share of primary goods in the export basket

A an?lise se deu no contexto em que os governos estaduais reagem ao abandono da linha desenvolvimentista da esfera federal, na d?cada de 1980, incorporando a??es caracter?sticas do chamado desenvolvimento regional end?geno e dotando os agentes locais de maior responsabilidade no processo de desenvolvimento. Justifica a necessidade da an?lise o seguinte cen?rio: os governos estaduais do nordeste brasileiro utilizam parte relevante de seus recursos para financiar a instala??o e amplia??o de empresas via incentivos fiscais, com vistas ? gera??o de renda e emprego, na espera de um aumento no produto e de uma mudan?a positiva no dinamismo econ?mico. Al?m disso, p?e-se em quest?o o fato de tais pol?ticas receberem tamanha import?ncia das administra??es estaduais para o objetivo de lograr o desenvolvimento regional. Coube apurar, portanto, o conte?do das a??es eleitas pelos governos estaduais para analisar o alcance dessas pol?ticas tanto no padr?o de crescimento, na transforma??o do setor industrial e no desenvolvimento da regi?o em aten??o ?s mudan?as nas estruturas produtivas estaduais. Devido ?s limita??es quanto ? disponibilidade de dados e ao tempo para realizar a pesquisa, foram eleitos tr?s estados para o estudo: Rio Grande do Norte, Maranh?o e Cear?. O trabalho considerou que, apesar da contribui??o das pol?ticas analisadas ao crescimento econ?mico, os estados subnacionais s?o incapazes de suprir a aus?ncia de ag?ncias de desenvolvimento estruturadas no ?mbito federal. / This research aimed to analyze the main government efforts to promote economic development in the Northeast, from 1985 to 2010, under the view that growth is crucial for increasing industrialization process and allows for more significant growth patterns. The analysis was the context in which state governments react to the abandonment of developmental line the federal level, in the 1980s, incorporating features of the actions called endogenous regional development and providing local players with greater responsibility in the development process. Justifies the need to analyze the following scenario: state governments in northeastern Brazil using relevant part of its resources to finance the installation and expansion of companies through tax incentives, with a view to generating income and employment, whilst waiting for an increase in output and a positive change in economic dynamism. In addition, it puts in question the fact that these policies receive such importance of state administrations for the purpose of achieving regional development. It was left to consider, therefore, the contents of the shares elected by state governments to examine the scope of these policies both in the pattern of growth, the transformation of the industrial sector and the development of the region attention to changes in state production structures. Due to limitations on the availability of data and time to carry out research, we were elected three states for the study: Rio Grande do Norte, Cear? and Maranh?o. The study found that, despite the contribution of policies analyzed to economic growth, sub-national states are unable to compensate for the lack of development agencies structured at the federal level.

Foram constatadas correntes harm?nicas em desconformidade com as normas, causadas pelo acionamento dos motores por meio de inversores de frequ?ncia. Para a solu??o do caso, este trabalho de conclus?o de Mestrado apresenta o projeto de filtros harm?nicos passivos em sintonia ?nica a serem instalados em paralelo nos terminais de baixa tens?o de cada um dos transformadores de 300 kVA da subesta??o que fornece energia el?trica para a Esta??o Elevat?ria de ?gua Bruta (EEAB) do Jiqui, da CAERN, principal capta??o de ?gua de Natal-RN. Os equipamentos promovem a redu??o das distor??es harm?nicas de corrente para os n?veis tolerados nas Normas IEC (International Electrotechnical Commission) 61000-3-4 e IEEE (Institute of Electrical and Electronic Engineers) 519. O sistema ? modelado desde a subesta??o da concession?ria at? as cargas energizadas pela subesta??o da CAERN e simula a opera??o dos filtros de 5?, 7?, 11? e 13? ordens de forma isolada e tamb?m interligada, obtendo as respostas para as implementa??es feitas para os diferentes fatores de qualidade. S?o avaliadas as novas harm?nicas de corrente e tens?o para cada frequ?ncia, bem como o comportamento do sistema na frequ?ncia. Observam-se as resson?ncias em s?rie dos filtros sintonizados e tamb?m as resson?ncias paralelas, sendo utilizada para tal a ferramenta computacional HARMZS, vers?o 1.8, desenvolvida pelo Centro de Pesquisas de Energia El?trica - CEPEL. Para as simula??es das correntes e tens?es ? usado o programa SCILAB, vers?o 5.5.1. / This work is based in a sanitation industry real case where electrical power quality parameters were diagnosed using electrical quantities meters during the predictive maintenance done in Companhia de ?guas e Esgotos do Rio Grande do Norte (CAERN). Divergent harmonic currents were observed against the standard recommendations, caused by the use of inverters for driving the motors. To solve this case, this final work presents passive harmonic filters single tuned to be instaled in parallel with the low voltage cables of each 300 kVA transformers that supplies power to raw water pumping station of Jiqui-CAERN, the main water supplier of Natal-RN. The equipments promote the reduction of harmonic current distortion to be within the tolerated levels to comply with the IEC (International Electrotechnical Commission) 61000-3-4 and IEEE (Institute of Electrical and Electronic Engineers) 519 standards. This study models the entire system, from the concessionary power substation until the final loads located in CAERN, and proposes the computer simulations of installing 5th, 7th, 11st and 13rd order filters isolated and integrated, obtaining the answers to all different applications performed with different quality factors. New harmonic current and voltage for each frequency, as well as the system behavior in the frequency a re evaluated. Series and parallel resonances in tuned filters are observed with the computational tool developed by Centro de Pesquisas de Energia El?trica (Electric Power Research Center) ?

Contudo, independentemente da maneira como estas formas se expressam na materialidade concreta, h? algo que as unifica: todas elas est?o marcadas pela exponencia??o da precariza??o e, consequentemente, dos in?meros efeitos negativos na vida dos sujeitos que necessitam vender sua for?a de trabalho para sobreviver. Tendo em vista essa premissa, o presente trabalho se dedicou a estudar, nos marcos das particularidades brasileira de transi??o entre o fordismo e o toyotismo, o que denominamos de configura??es comp?sitas das condi??es e rela??es de trabalho processadas no ?mbito da ind?stria t?xtil norte-rio-grandense. Para tanto, norteados pelo materialismo hist?rico-dial?tico, fizemos uso da pesquisa social em sua vertente qualitativa, com utiliza??o de entrevistas semiestruturadas, al?m de revis?o de literatura, pesquisa documental e utiliza??o do caderno de campo. A partir das nossas incurs?es, podemos constatar que entre o lapso temporal que se estende da d?cada de 1990 aos anos atuais, a ind?stria t?xtil potiguar vem passando por um processo de sucessivas e intensas transforma??es em seu modus operandi, voltado mais especificamente para a organiza??o e a gest?o do trabalho provocando, concomitantemente, diversos rebatimentos para todo o operariado. / In line with the process of financialization and globalization of capital, which has intensified in all latitudes of the globe, the world of work is permeated by his determinations arising and also has been (re) setting from numerous changes expressed by example, in the unbridled expansion of temporary forms of work activities, and flexible outsourced by the growth of informality, forming a new morphology of work. However, regardless of how these forms are expressed in concrete materiality, there is something that unifies: all of them are marked by exponentiation of insecurity and hence the numerous negative effects on the lives of individuals who need to sell their labor power to survive. Given this premise, the present work is devoted to study, within the framework of the Brazilian particularities of transition between Fordism and Toyotism, what we call composite settings of the conditions and labor relations processed within the North river- textile industry Grande. To this end, guided by historical and dialectical materialism, we made use of social research in its qualitative aspect, using semi-structured interviews, in addition to literature review, information retrieval and use of field notes. From our raids, we note that between the time span stretching from the 1990s to the current year, the Natal textile industry has been undergoing a process of successive and intense changes in their modus operandi, geared specifically to the organization and labor management causing, concomitantly, several repercussions for the entire working class.

No. of bitstreams: 1 EuripedesMJ_DISSERT.pdf: 4309763 bytes, checksum: b3fa0816ee03d93a87822302b0adb8fb (MD5) Previous issue date: 2011-12-21 / The strengthening of the domestic industry in Brazil required the modernization, mechanization and expansion of salt production. Thereafter the production of sea salt started to be made in a process of continuous flow, where the product is constantly stored in yards, with daily movements in and out of salt. Thus far, the major bottleneck found in this production process is the control of production, because due to the large amount produced and variety of losses existing in the various stages of production there are not a regulated and safe way to control inventories with accuracy and speed demanded. In a typical case with a salt marsh company of Rio Grande do Norte state, salt produced is stored in two open courtyards and inventory control of salt made by carrying input / output relationship of salt in each storage yard. This work developed a conceptual model of inventory control, based on topography, adopting surveys into one of the courtyards of the company. There were 25 biweekly survey measurements over a year book to generate digital models representing the stock. For each measurement, results were compared with the values of inventory accounting provided by the salt marsh in order to identify existing losses and mark out the sales department on the actual stock available at each measurement date. Inventories calculated by the model indicated losses of 6,349 tonnes for the period of one year book and 3,279 tonnes for the period between harvests, when compared to the accounting control / O fortalecimento da ind?stria nacional nos ?ltimos 20 anos exigiu a moderniza??o, mecaniza??o e amplia??o da produ??o salineira. A partir disso a produ??o de sal marinho passou a ser feita num processo de fluxo cont?nuo, onde o produto ? constantemente estocado em p?tios, com movimenta??es di?rias de entrada e sa?da de sal. At? o presente, o grande gargalo encontrado neste processo produtivo tem sido o controle da produ??o, pois devido a grande quantidade produzida e a diversidade de perdas existentes nas diversas etapas do processo de produ??o n?o se tem uma forma que seja regulamentada e segura para controlar os estoques com precis?o e velocidade necess?rias. No estudo de caso realizado em uma salina com processo de produ??o tipicamente adotado no RN, o sal produzido ? estocado em dois p?tios abertos ao ar livre, sendo o controle do estoque de sal feito de forma cont?bil pela rela??o entrada / sa?da de sal em cada p?tio de estocagem. Neste trabalho desenvolveu-se um m?todo conceitual do controle de estoque baseado na Topografia, utilizando medi??es realizadas em um dos p?tios da empresa. Foram executadas 25 medi??es topogr?ficas quinzenais ao longo de um ano cont?bil para gerar modelos digitais representativos do estoque. Para cada medi??o foram comparados os resultados do modelo com os valores do estoque cont?bil da salina de forma a identificar as perdas existentes e informar ao setor de vendas o estoque real dispon?vel em cada data medida. Os estoques calculados pelo modelo indicaram perdas de 6.349 t para o per?odo anual e de 3.279 t para o per?odo da entressafra, quando comparadas ao controle cont?bil

Para dar suporte a esse estudo, desenvolvemos um modelo formal macroecon?mico voltado para proje??o, aqui constru?do a partir de Louren?o e Roos (2015) e dos principais desenvolvimentos te?ricos recentes do modelo de crescimento sob restri??o externa. A simula??o do desempenho da ind?stria e da economia brasileira foi gerada no ?mbito de tr?s diferentes cen?rios, todos condicionados ao atual modelo de gest?o da pol?tica macroecon?mica do pa?s. O Cen?rio 1 representa o desdobramento esperado dos eventos econ?micos na aus?ncia de qualquer pol?tica industrial adicional. No Cen?rio 2, inclu?mos a suposi??o de que, a partir de 2016, o governo implementa uma pol?tica industrial via redu??o da al?quota tribut?ria do setor para 0%. Por fim, no Cen?rio 3 adotamos a suposi??o de que opera uma pol?tica industrial que n?o se manifesta pela mudan?a da al?quota tribut?ria, mas sim por mecanismos de seletividade de cr?dito, pol?tica comercial, cient?fica, tecnol?gica etc., os quais geram um aumento anual de 1,0 ponto percentual no peso das exporta??es industriais no total das exporta??es, e uma redu??o de mesmo ponto percentual no peso das importa??es do referido setor no total das importa??es. Os resultados obtidos sugerem que a implementa??o de uma pol?tica industrial do tipo especificamente considerado no Cen?rio 3, bem como uma mudan?a no atual modelo de gest?o da pol?tica macroecon?mica se fazem importantes para alavancar o crescimento econ?mico brasileiro; caso contr?rio, o pa?s seguir? apresentando baixas taxas de crescimento. / Having as motivation the discussion that has been developing over the past few years about the development of the Brazilian industry and its impacts on the trajectory of economic growth, in this dissertation we aimed perform a simulation analysis on the effect of the implementation of a supposed industrial policy on the potential performance of the industrial sector and the Brazilian economy in the 2016-2025 period. To give support to this study, we developed a formal macroeconomic model oriented to projection, built here from Louren?o and Roos (2015) and the main recent theoretical developments of the growth model under external constraint. The simulation of industry performance and the Brazilian economy was generated under three different scenarios, all conditioned to the current macroeconomic policy management model of the country. The Scenario 1 represent the expected development of economic events in the absence of any further industrial policy. In Scenario 2, we included the assumption that, from 2016, the government implements an industrial policy by reducing to 0% the tax aliquot in the industry. Finally, in Scenario 3 we adopt the assumption that operates an industrial policy that does not manifest itself by changing the tax aliquot, but by credit selectivity mechanisms, trade, scientific and technological policy etc., which generate an annual increase of 1.0 percentage point in the weight of industrial exports in total exports, and a reduction of the same percentage point in the share of imports of that sector in total imports. The results suggests that the implementation of an industrial policy of the type specifically considered in Scenario 3, as well as a change in current macroeconomic policy management model are importante to leverage Brazilian economic growth; otherwise the country will follow featuring low growth rates.

Nesse contexto, a Salina Diamante Branco - SDB, em Galinhos, descarta toda a salmoura de processo na ?rea estudada, o rio Tom?s-Galinhos. Desse modo, ? essencial avaliar os poss?veis impactos dessa atividade salineira no corpo d??gua adjacente. Dessa forma, realizou-se um monitoramento f?sico-qu?mico da qualidade de ?gua e sedimento para obten??o de um diagn?stico ambiental, incluindo os indicadores de polui??o, o ?ndice de Qualidade de ?gua ? IQA e o ?ndice de Toxicidez. A maioria das amostras foram coletadas de julho de 2014 a abril de 2016, trimestralmente, em um total de 32 coletas em mar? alta e baixa. Al?m dessas coletas, houveram mais duas de metais pesados em ?gua e sedimento. Todos os resultados foram relacionados com os padr?es exigidos pelas resolu??es 357, de 17 de mar?o de 2005 e 344, de 25 de mar?o de 2004, ambas, do Conselho Nacional do Meio Ambiente ? CONAMA. Para os par?metros n?o relacionados nas normas citadas, estes, foram avaliados perante sua variabilidade no corpo d??gua. A grande maioria dos resultados obtidos apresentaram-se sem grandes varia??es mantendo as caracter?sticas naturais do estu?rio, fato que levou o IQA de todos os pontos como de qualidade BOA. Em contrapartida, alguns teores de oxig?nio dissolvido, f?sforo total em ?gua e sedimento, e clorofila obtidos, indicaram uma tend?ncia ? contamina??o por mat?ria org?nica. No entanto, esses contaminantes s?o oriundos de outras atividades nas comunidades circunvizinhas. Janeiro e abril, de maiores temperaturas, em geral, apresentaram menores valores de oxig?nio dissolvido. Em rela??o aos metais na ?gua, praticamente todos estavam abaixo do limite de detec??o do ICP-OES utilizado, ou, abaixo dos limites exigidos pelo CONAMA, indicando que estes metais tendem a ser carreados pela din?mica das mar?s ou precipitados no sedimento, caracterizando-se como IT igual a 1, isto ?, contamina??o ausente. Em rela??o aos metais no sedimento obteve-se tamb?m aus?ncia de toxicidade. Os descartes de salmoura, a priori, influenciam no comportamento da salinidade, no entanto, n?o alteram as caracter?sticas naturais do rio, mantendo um intervalo fixo de salinidade no decorrer dos anos. Em mar? baixa e nos per?odos de escassez de chuvas, foi poss?vel verificar uma tend?ncia a uma maior concentra??o dos sais e de nutrientes. A localiza??o caracter?stica de cada ponto de coleta tamb?m influenciou nos resultados. Os valores obtidos de c?lcio, magn?sio e o pH b?sico s?o caracter?sticos do corpo d??gua estudado e n?o sofreram grandes varia??es. / The Rio Grande do Norte is the largest producer of salt, sodium chloride, the country and holder of 97% of all salt produced. In this context, Salina Diamante Branco - SDB in Galinhos, dismisses the whole process of brine in the study area, the river Thomas-Galinhos. Thus, it is essential to assess the possible impacts of this Salineira activity in the body of water adjacent. Thus, there was a physical-chemical monitoring of water quality and sediment to obtain an environmental assessment, including indicators of pollution, the Water Quality Index - IQW and Toxicidez Index. Most samples were collected from July 2014 to April 2016, three months, for a total of 32 collections for high and low tide. In these collections, there were two other heavy metals in water and sediment. All results were related to the standards required by resolutions 357 of 17 March 2005 and 344 of 25 March 2004, both the National Environmental Council - CONAMA. For non listed in the cited standards parameters, these were evaluated before its variability in the water body. The vast majority of results presented without great variations while maintaining the natural characteristics of the estuary, a fact that led the IQW all points as quality GOOD. In contrast, some levels of oxygen dissolved total phosphorus in water and sediment, and obtained chlorophyll, indicated a tendency to contamination by organic matter. However, these contaminants are from other activities in the surrounding communities. January and April, higher temperatures generally showed lower values of dissolved oxygen. Regarding metals in water, almost all were below the ICP-OES detection limit or below the limits required by CONAMA, indicating that these metals tend to be adduced by the dynamics of tidal or precipitated sediment, characterizing as IT = 1, absent contamination. Regarding metals in sediment was obtained also no toxicity. Brine disposal a priori influence the behavior of the salinity, however, do not alter the natural characteristics of the river, keeping a fixed range of salinity over the years. At low tide and periods of drought, we found a trend to a higher concentration of salts and nutrients. The location characteristic of each collection point also influenced the results. The values of calcium, magnesium and alkaline pH are characteristic of the body of water and studied underwent no significant changes.

Sua conceitua??o transborda o crescimento num?rico da economia e tangencia a concep??o senesiana que conjuga desenvolvimento e liberdade. Essa inser??o serve ? investiga??o das origens e dos prop?sitos da pol?tica brasileira de Conte?do Local no setor de petr?leo. Essa descoberta leva inexoravelmente ao sistema de certifica??o de Conte?do Local, logo percebido como ferramenta ? disponibilidade do desenvolvimento do pa?s. Abordar-se-?, ao longo da pesquisa, a rela??o intuitiva entre a Constitui??o e o Desenvolvimento, no contexto da ind?stria energ?tica petrol?fera, bem como a inclus?o do sistema de certifica??o nesse bin?mio, al?m dos pr?prios comandos constitucionais que guardam particular interesse n?o s? com a promo??o do desenvolvimento da ind?stria e do pa?s, mas tamb?m com a pr?pria legitimidade a pol?tica de Conte?do Local, de modo que o seu sistema de certifica??o deixa de estar ? disponibilidade e passa a ser instrumento do interesse p?blico desenvolvimentista. O alcance desses objetivos se dar? com a ado??o dos processos metodol?gicos dedutivo e dial?tico e de t?cnicas de coleta de documenta??o indireta, com pesquisa documental e pesquisa bibliogr?fica, m?todos que revelar?o as lacunas hodiernamente existentes no modelo posto, sobretudo diante da n?o consecu??o dos desideratos desenvolvimentistas pensados no in?cio da pol?tica, dado o alto ?ndice de n?o cumprimento da cl?usula de Conte?do Local. / This present work has as its context the development and its perceptions, all in the intente of framing it as integrating juridical element of the Brazilian system of norms, especially with its predilection by the Constitution. Your conceptualization overflows the numeric growth of the economy and tangents the Senesian conception that combines development and freedom. This insertion serves to investigate the origins and purposes of the Brazilian local content policy in the petroleum sector. This discovery leads inexorably to the local content certification system, soon perceived as a tool for the availability of the country's development. To this purpose, an intuitive relationship between the Constitution and Development will be tackled throughout the research, all in the context of the oil industry, not only with a promotion of the development of industry and the country, but also with a political legitimization of Local content, so that your certification system is no longer available and passes through an instrument of public interest. These objectives will be achieved through the adoption of deductive and dialectical methodological processes and indirect documentation collection techniques, with documentary research and bibliographical research, methods that will reveal the existing gaps in the model post, especially in the face of the failure to achieve the developmentalist ideals thought at the beginning of the policy, given the high rate of non-compliance with the Local Content clause. It is intended to emphasize the developmental aspect of this system, establishing it as the ultimate goal of the local content policy, proposing, moreover, a more protective model and closely linked to the fundamental objectives of the Republic of guaranteeing national development and the reduction of regional inequalities.

Environmental Accounting is the system of information which main aim is to gather, measure and disclose the environmental transactions seeking to exercise the important role of communication vehicle between company and society. In this context, the accounting statements deserve attention and special study, regarding that they represent the main disclosure channel of economic-environmental items of which the Accounting uses. The objective of this work was to analyze a sample of accounting statements published in Brazil with the objective of verifying how the investments, liabilities and environmental costs have been disclosed. Unhappily, the accounting statements of this companies had revealed little adequate to the new necessities of the users of the accounting information, and parallel, insufficient to take care of to the requirements of NBC T 15 - Information of Social and Ambient Nature, approved for the Resolution of the Federal Advice of Accounting - CFC n?? 1.003, that it will enter in vigor from 1?? of January of 2006. / As empresas, como parte integrante da sociedade, est??o sendo fortemente demandadas a cumprirem metas ambientais, al??m das econ??micas; demonstrando que, al??m do retorno econ??mico gerado aos acionistas, tamb??m est??o gerando retorno social ??s comunidades em que se encontram inseridas. A Contabilidade Ambiental apresenta-se como o sistema de informa????es que tem como finalidade principal coletar, mensurar e evidenciar as transa????es ambientais visando a exercer o importante papel de ve??culo de comunica????o entre a empresa e a sociedade. Neste sentido, as demonstra????es cont??beis merecem aten????o e estudo especiais, haja vista que representam o principal canal de evidencia????o de itens econ??mico-ambientais do qual faz uso a Contabilidade. O objetivo deste trabalho foi o de analisar uma amostra de demonstra????es cont??beis publicadas no Brasil, das empresas Petrobr??s, Braskem, Refap, Copesul, Bunge Fertilizantes, Basf, Petroqu??mica Uni??o e OPP, todas do ramo qu??mico e petroqu??mico, no intuito de verificar como t??m sido evidenciados os investimentos, passivos e custos ambientais pelas referidas empresas. Infelizmente, as demonstra????es cont??beis dessas companhias mostraram-se pouco adequadas ??s novas necessidades dos usu??rios da informa????o cont??bil, e paralelamente, insuficientes para atender ??s exig??ncias da NBC T 15 - Informa????es de Natureza Social e Ambiental, aprovadas pela Resolu????o do Conselho Federal de Contabilidade - CFC n?? 1.003, que entrar?? em vigor a partir de 1?? de janeiro de 2006.
