Developmental Challenges and Opportunities of Brazil in the 21st Century

Ribeiro, Henrique Ruda Vianna 01 December 2015 (has links)
As Brazil develops into the first South American world power many changes in its society, economy and political system are necessary for a successful transformation. Nevertheless this is no easy task as the country battles corruption, vast inequality and a severe problem with freedom of information within the media. For decades the Brazilian mainstream media has been controlled by elite political forces together with elite families influencing and controlling many factors that are responsible for social, economic and political development. As new developments and implementations in the last fifteen years have been ongoing within Brazil, such as welfare programs, social reforms, hosting of international sporting events and the emergence and popularity of social networking technology, millions within the Brazilian Nation have been able to ascend out of poverty and into a new era of diversity of information, political participation and greater awareness of the problems within their own society. The time has finally come of when the Brazilian people have the ability to react and mobilize against the forces and factors that for decades have perpetuated several unfavorable conditions within Brazil.

Made available in DSpace on 2015-09-25T12:23:32Z (GMT). No. of bitstreams: 1 MARIA_JOSE_COMANDANTE_COSTA.pdf: 1369694 bytes, checksum: 2b63fa3023c60448918ab6ae6b29a54f (MD5) Previous issue date: 2006-02-21 / The research was realized in four phases. In the 1st phase, interviews were accomplished with proprietors of car-washes with the objective of knowing your environmental and social impacts. In the 2nd phase synthetic effluents of car-washes were treated during 147 days in batch anaerobic reactors with five different oil and detergent concentrations. In the 3rd phase six reactors were monitored in batch form, during 20 days, with substrate containing high oil concentrations (0,5 to 2,5 g.l-1) and surfactants concentrations (5,0g.L-1). These treatments were realized with purpose to verified the relation between oil concentration and inhibition of the biologic activity. In the 4th phase six batch anaerobic reactors, with different proportions of the surfactant, were monitored during 35 days. The concentrations of organic matter influent and effluent were analyzed in all the treatments and in the sludge were determined solid concentration. Daily the biogas produced was measures and characterized. In the 2nd phase the average removal of soluble COD was about 82%, for a monitoring period of 18 days. For raw COD during 100 days of operation the average removal was approximately 76% and the production of methane was directly proportional the substrate concentrations. It was verified that the anaerobic biological activity occurs in surfactant concentration below 0,5 g.L-1, and starting from that concentration it begins to happen inhibition of the process. / O presente trabalho foi desenvolvido em quatro fases. A primeira fase teve o objetivo de levantar dados sobre os impactos ambientais e sociais causados pelos lava-jatos. Para tanto, foram realizadas entrevistas com seus proprietários. Na segunda fase, foram tratados anaerobiamente, durante 147 dias, em reatores de batelada, efluentes sintéticos de lava-jatos com cinco diferentes concentrações de óleo e detergente. Na terceira fase, foram monitorados seis reatores anaeróbios, em regime de batelada, durante 20 dias, com substratos contendo altas concentrações de óleo (0,5 a 2,5 g.L-1) e surfactantes (5,0 g.L-1). Estes tratamentos tiveram por finalidade verificar se, com o aumento da concentração de óleo, haveria inibição da atividade biológica. Na quarta fase, foram realizados, anaerobiamente, em reatores de batelada, durante 35 dias, seis experimentos com diferentes concentrações de surfactante para verificar que concentração inibiria o processo biológico anaeróbio. Para todos os tratamentos foram analisadas as concentrações de matéria orgânica (DQO) afluente e efluente, bem como as concentrações de sólidos do lodo. Diariamente, foram realizadas leituras do volume e da composição do biogás. Como resultados da segunda fase, verificaram-se remoções de DQO solúvel média de 82% aos 18 dias e para DQO bruta em torno de 76% para os cinco tratamentos, durante 100 dias de operação. A produção de metano foi diretamente proporcional às concentrações dos substratos. Constatou-se que a atividade biológica anaeróbia ocorre numa concentração de surfactante de até aproximadamente 0,5 g.L-1, sendo que a partir daí, começa a ocorrer inibição do processo.

In this context, this study aimed to conduct an environmental diagnosis of the wastewater of washing enterprises for vehicles in Mossoró, RN. It was divided into two phases: the first, was conducted the survey city is of the car wash , and identified 34 businesses under the consultancy SEBRAE, within this field sampling were selected, at random, 13 enterprises, applied a questionnaire directed to owners with questions pertaining to the productive process, the source and destination of the water used; in the second stage was held the physico-chemical characterization of wastewater from three of the 13 companies surveyed in the previous step. The parameters analyzed in characterization were: oils and grease, BOD, COD, OD, ST, TSS, turbidity, total Nitrogen, P-total, temperature, Turbidity and pH. The results demonstrate that the wastewater from washing vehicles feature high concentrations of organic matter, oils and greases, turbidity and solid, which are in disagreement with specific environmental legislation. The evaluation demonstrated that although companies performed a primary treatment Water Separators and Oil (SAO), the effluent are not fit to be released into water bodies; It was found that the legal adequacy of companies Lava Jato regarding the treatment of effluents occurs only structurally. The owners are not appropriate of methods and of control standards established by current legislation for effluent discharge / Estima-se, que está sendo produzida mensalmente na cidade em Mossoró, 6.096,55m3 de residuárias de lavagem de veículos, possivelmente contaminada. Neste contexto, este trabalho teve como objetivo geral realizar um diagnóstico ambiental das águas residuárias de empreendimentos de lavagem de veículos em Mossoró, RN. Para tanto, foi dividido em duas fases: na primeira, foi realizado o levantamento das empresas de lavagem de veículos da cidade, e identificou-se 34 empresas sob a consultoria SEBRAE, dentro deste campo amostral foram selecionados, aleatoriamente, 13 empreendimentos, empregou-se um questionário dirigido aos proprietários com perguntas referentes ao processo produtivo, a origem e o destino da água usada; na segunda etapa foi realizada a caracterização físico-química das águas residuárias de três das 13 empresas pesquisadas na etapa anterior. Os parâmetros analisados na caracterização foram: óleos e graxas, DBO, DQO, OD, ST, SST, turbidez, Nitrogênio total, P-total, Temperatura, Turbidez e pH. Os resultados demonstram que as águas residuárias de lavagem de veículos apresentam altas concentrações de matéria orgânica, óleos e graxas, turbidez e sólidos, que estão em discordância com a legislação ambiental específica. A avaliação demonstrou que embora as empresas realizem um tratamento primário com Separadores de Água e Óleo (SAO), os efluentes não estão aptos para serem lançados em corpos hídricos; Constatou-se que a adequação legal das empresas Lava Jato quanto ao tratamento dos efluentes gerados ocorre apenas estruturalmente. Os proprietários não estão apropriados de métodos de controles dos padrões estabelecidos na legislação vigente para lançamento de efluentes

La investigación tiene como objetivo central estudiar como los criterios de tratamiento informativo relacionados a hechos políticos que se ven afectados o alterados por la posición política de un diario. Para ello se ha elegido un caso específico: la relación entre Keiko Fujimori, excandidata presidencial y lideresa de Fuerza Popular, y el caso Lava Jato. Se realizará un estudio de tres hitos importantes de este caso los cuales son la detención preliminar a Keiko, los cambios que se realizaron en el Ministerio Público y la apelación de la prisión preventiva a Keiko. Se hará un análisis comparativo cualitativo de las notas emitidas por La República y La Razón para entender este fenómeno de la comunicación. / The main objective of the research is to study the information treatment criteria related to political events that are affected or altered by the political position of a newspaper. For this, a specific case has been chosen: the relationship between Keiko Fujimori, former presidential candidate and leader of Fuerza Popular, and the Lava Jato case. A study of three important milestones of this case will be carried out, which are the preliminary arrest of Keiko, the changes that were made in the Public Ministry and the appeal of the preventive detention to Keiko. A qualitative comparative analysis will be made of the notes issued by La República and La Razón to understand this phenomenon of communication. / Trabajo de investigación

No. of bitstreams: 1 Wilson Cedraz da Silva.pdf: 3054125 bytes, checksum: 19e4d7597d3f7a910644c6b4f313b9ec (MD5) / O objetivo desta dissertação é analisar os sistemas de governança corporativa, gestão de riscos e conformidade da Petrobras e da Eletrobras, antes e depois da Operação Lava Jato, e verificar se foram realizadas as mudanças adequadas para a remediação das deficiências que levaram aos desvios de recursos. A relevância do trabalho está, principalmente, na análise das medidas que foram tomadas pelas empresas, diante das evidências de que um complexo esquema de corrupção vinha realizando grandes desvios de recursos, nestas que são as maiores estatais brasileiras, gozavam de boa reputação e tinham seus sistemas de controles certificados nacional e internacionalmente. Através de uma pesquisa documental e de outras fontes, as ações das empresas foram analisadas, com suas respectivas legislações sobre contratações, considerando os desdobramentos da Operação Lava Jato. A análise de conteúdo foi utilizada para avaliar as remediações das deficiências nos controles internos e as alterações na governança corporativa, gestão de riscos e conformidade, comunicados pelas empresas através de seus Formulários de Referência. Finalmente, foi aplicada a técnica da triangulação, relacionando os dados da análise de conteúdo com os da pesquisa documental e confrontando com as melhores práticas levantadas através da pesquisa bibliográfica. O estudo mostra que as principais causas dos desvios estão fortemente relacionadas aos vícios no desenho institucional brasileiro. A conclusão do trabalho mostra que apesar de ambas as empresas terem apresentado propostas de remediação das deficiências, mediante alterações em seus sistemas de governança corporativa, gestão de riscos e conformidade, em concordância com os padrões do COSO e ISO 31000, apenas a Petrobras implementou efetivamente tais alterações, enquanto que a Eletrobras não havia implementado as necessárias remediações, até o fechamento da presente pesquisa. / ABSTRACT The goal of this work is to analyze the main changes in the corporate governance, risk management and compliance systems of the Petrobras and Eletrobras and verify if these changes were appropriate to remedy the deficiencies that led to the misappropriation of resources identified by Lava Jato Operation. The relevance of the research is mainly on the analysis of measures taken by the two companies based on the evidence that a complex corruption scheme had been carrying out large deviations of resources despite the fact that the two companies are the largest Brazilian state companies, whose reputation was good and their control systems certified nationally and internationally. Through documentary research and others sources it is presented an analysis of the events and the measures that both companies implemented. To evaluate the remediation of the deficiencies in internal controls and governance changes, submitted by the companies, it was used content analysis. Finally, the technique of triangulation was applied, relating the content analysis data with the documentary research and comparing the best practices raised through literature. The main problems were intrinsically associated with the Brazilian institutional problems. As a result, it was possible to identify that both companies submitted control remediation proposals and governance changes in accordance with the standards of COSO and ISO 31,000. However, only Petrobras has implemented a major restructuring in its systems of corporate governance, risk management and compliance.
