Arrecadação governamental e sistema tributário como resultados políticos

Esse paper introduz escolha simultânea do sistema político, sistema tributário e composição do gasto governamental em um modelo macroeconômico dinâmico de economia política com mercados incompletos onde o tamanho das arrecadações governamentais deve ser decidido a cada período. Além disso avalia o efeito de cada uma dessas instituições sobre a política fiscal de equilíbrio político. A inclusão dessas variáveis torna o modelo mais realista e possibilita o estudo de como a política econômica do governo é escolhida pela sociedade. A especificação mais geral do modelo calibrada para os EUA foi capaz de aproximar de maneira satisfatória a taxa efetiva e a relação tributária capital-trabalho observada nos dados.

Política cultural audiovisual sob o prisma do mecanismo de investimento reembolsável da RioFilme

O presente trabalho busca analisar o resultado da restituição das receitas investidas nos projetos audiovisuais pela empresa RioFilme, no período de 2009 a 2013, por meio do mecanismo de investimento reembolsável, visando identificar a possibilidade de retroalimentação para novos investimentos. A RioFilme, que é uma empresa pública de investimentos em audiovisual da Prefeitura do Rio de Janeiro, realiza investimentos reembolsáveis, nos quais adquire participação nas receitas dos projetos; e não reembolsáveis, em que não há possibilidade restituição financeira para a empresa. Para a operacionalização da pesquisa foi realizada a análise documental de 79 processos administrativos e extraídos dados dos investimentos financeiros realizados RioFilme no setor audiovisual carioca no período de 2009 a 2013. O setor audiovisual brasileiro possui grande intervenção governamental, seja ela de forma direta, como também indireta, através das leis de incentivo à cultura, que utilizam a renúncia fiscal. Este modelo não traz restituição direta para o ente estatal, e consequentemente não possibilita a retroalimentação financeira do Estado para novos investimentos. Desta forma, a análise dos modelos alternativos de financiamento do setor audiovisual, como o mecanismo reembolsável utilizado pela RioFilme é de suma importância para a política cultural audiovisual brasileira, tendo em vista que neste modelo de investimento utilizado pela mesma há possibilidade de restituição financeira direta, possibilitando sua retroalimentação para investimentos em novas obras audiovisuais.

Avaliação do programa escola ativa como política pública para escolas do campo com turmas multisseriadas: a experiência em jardim do seridó/rn (1998-2009)

This work aims at developing an evaluation of the implementation of the Program Escola Ativa as a public policy for rural schools with combined grade classrooms in Jardim do Seridó RN (1998 2009) focusing on the following dimensions: school s physical environment, training, follow up, and didactic usage of the methodology. In order to develop this research we refer to the literature that analyzes the cycle of policies (FREY, 2000). In this approach, evaluation represents an important step in the process of analyzing the implementation of public policies, as a way of measuring up their performance, as well as a guide for realignments and redefinitions (PRESSMAN; WILDAVSKY, 1998). In order to accomplish this function, the evaluator of policies must be acquainted with scientific concepts and methods that consist of describing, interpreting and analyzing the policies in the governmental sphere (MENY; THOENIG, 1992; LIMA JÚNIOR, 1978). In this perspective, we intend to investigate whether in its proposition of minimizing the blanks in the Brazilian educational system, the implementation of the Program would be contributing to the improvement of the political-pedagogical practices in the rural schools with combined grade classrooms in Jardim do Seridó RN. In order to do this research, we have developed a theoretical-methodological matrix made of analysis dimensions, variables, indicators and instruments, such as literary revision, documental analysis, semi-structured interviews with four teachers and three supervisors that work and/or have worked in Escola Ativa in that town in the period comprised among 1998 2009, besides notes taken from field observation and photographs from four rural schools with combined grade classrooms. With this research we have identified that the Program, at a national level, has gone through different phases in its implementation process, for the town was not ready to fully take the responsibilities of the autonomous expansion, in 2002. From that period on, the execution of Escola Ativa has suffered several discontinuities, such as the lack of professional training and supervising. It is also noted that the methodology contributes to the dynamization of the didactic-pedagogical activities and promotes the cooperation and autonomy of the students in the organization and the applicability of the components of the curriculum, especially of Governo Estudantil and Cantinhos de Aprendizagem. Although the directions of the Program (BRASIL, 2005) point out that Escola Ativa has among its principles social transformation, we identified that, isolated, the initiative is not capable of promoting the changes that the rural schools need, namely investments in the physical, material, pedagogical and technological infra-structure, besides the estimation and a career plan for the teachers. In a general draft of the results of this research, we realized that some aspects presented about the peculiarities of Escola Ativa in Jardim do Seridó as a governmental Program, reinforce the need for the public policies to be evaluated, in order to confront critic and operationally the planning with the practice, revising action, whenever necessary

Avaliação de diferentes processos oxidativos avançados no tratamento de resíduos de petróleo

The petroleum industry deals with problems which are difficult to solve because of their relation to environmental issues. This is because amounts of residue are generated which vary in type and danger level. The soil contamination by non aqueous liquid phase mixtures, specifically hydrocarbon petroleum has been a reason for great concern, mainly the aromatic and polycyclic aromatic, which present risk to human health due to its carcinogenic and mutagenic character. The Advanced Oxidative Processes (AOP) are efficient technologies for destruction of organic compounds of difficult degradation and, often, they are present in low concentrations. They can be considered clean technologies, because there is no formation of solid by-products or the transfer of pollutor phases. This work focuses on the study of the degradation of petroleum industrial waste, by Advanced Oxidation Processes. Treatments tackling petroleum residues, contaminated soil, and water occurring in the production of petroleum reached the following Polycyclic Aromatic Hydrocarbons (PAH) degradation levels: solid residues 100% in 96 treatment hours; water residue - 100% in 6 treatment hours; soil contamination (COT degradation) - 50.3% in 12 treatment hours. AOP were effective in dealing with petroleum residues thus revealing themselves to be a promising treatment alternative

Caracterização dos resíduos esgotados de sistemas de tratamento individual de esgotos de Natal

In Natal still dominates the use of individual disposal systems for domestic sewage, once only 29% of the city has a sewarage system. Wastes that are accumulated in these individual treatment systems should be exhausted periodically, service provided by collector entrepreneurs. Some of these companies causing major damage to the environment. In Natal, only two companies have their own septage (RESTI) treatment system, which were designed with parameters from domestic sewage generating strain and inefficient systems. Therefore, the characterization becomes essential as a source of parameters for their design. Thus, this work presents the physical-chemical and microbiological characterization of waste pumped from individual sewage treatment systems. Samples collections were made weekly from 5 different trucks at the reception point on the treatment plant on the point of the preliminary treatment. From each truck it was taken 5 samples during the discharge in order to make a composite sample. Afterwards, samples were carried out to laboratory and analyses for determination of temperature, pH, conductivity, BOD, COD, nitrogen (ammonia e organic), alkalinity, oils, phosphorus, solids, faecal coliforms and helminth egg. The results were treated as a single database, and ranked according to its generating source (multi and single house, lodging, health, services and / or food), area of origin (metropolitan, south and north) and type of system (cesspits, septic tank and / or sink). Through these data it was possible to verify that the type of system adopted by most in Natal and the metropolitan region is cesspit, besides to confirm the difference between the septage of areas with a population have different social and economical characteristics. It was found that the septage have higher concentrations than domestic sewage, except for thermotolerant coliforms that showed concentrations of 1,38E+07. Among the parameters studied, is the median values identified for COD (3,549 mg / L), BOD (973mg / L) and total solids (3.557mg / L). The volatile fraction constitutes about 70% of the total solids of the septage. For helminths has been a median of 7 eggs/L. In general, the characteristics of the waste followed the variability found in the literature reviewed for all variables, showing high amplitudes

Avaliação da eficiência de lagoas de estabilização no tratamento de resíduos esgotados de fossas sépticas

Because of disability in public policy development in mind to attend issues of sanitation in the municipalities, companies known as "clean-blue" appeared proposing to solve a simple collection and management of wastewater produced in single or multifamily residences, commercial, hospitals, etc. In the case of an activity in which there are no worries about the fate of sewage, emerged some doubts about the degree of health and environmental safety in these companies. Traditionally, most of them makes the provision of waste depleted soil or wetland, open, usually located on the outskirts of cities (MENESES, 2001). In turn, the sludge from septic tanks exhausted, provided no technical criteria - in the soil, rivers and as an agricultural fertilizer put in risk the health of the population and environmental quality. This work was entered in the search network 5 of the Notice of the Research Program in Sanitation - PROSAB-5, aimed to study the theme 'Characterization and study of alternative ways of treating sludge from septic tanks in the city of Natal, RN', proposing to evaluate the performance of the use of stabilization ponds as a system to handle waste from septic tanks exhausted. A series of lakes studied belong to one of the largest clean-pit of Natal, consisting of two anaerobic ponds, one facultative and maturation, and a tank disinfection, the wastewater being released in the Potengi River. Samples were collected between the months of October 2007 to October 2008, at six points previously defined and judged as more appropriate to what is proposed study. The analysis results in field and laboratory showed the most significant removal of COD (88.93%), total suspended solids (94.87%), organic nitrogen (66.87%) and thermotolerant coliforms (99.88%). Some results have not reached the expected because the system under study had operating problems that have undermined the efficiency of the reactors

Fortalecimento do controle interno governamental: diagnóstico e propostas para a Controladoria Geral do Estado do RN

O objetivo deste trabalho é fazer uma proposta de intervenção na Controladoria Geral do Estado do Rio Grande do Norte, com o intuito de fortalecê-la, tendo como base a Emenda Constitucional nº 45/2009, que propõe a inserção das macrofunções do Controle Interno: Auditoria Governamental, Controladoria, Corregedoria, Ouvidoria e Carreiras Específicas para os órgãos de Controle Interno. Para dar suporte a proposta, foi feita uma revisão da literatura sobre controles públicos, controle interno governamental, macrofunções do controle interno e sobre carreiras públicas no Brasil. Para propor as mudanças foram realizados dois diagnósticos no órgão, por meio de entrevistas, e constatados problemas na área de gestão organizacional e de pessoal. Diante dos resultados apresentados por meio dos diagnósticos, foram propostas mudanças e feitas comparações entre a estrutura atual e a proposta, procurando evidenciar a vantagem da última sobre a primeira, em termos de eficiência operacional, economia de meio, economia de execução, amplitude no atendimento a população, proteção e combate à corrupção, fomento ao controle social, promoção da cidadania e justiça social

Análise da rede política do turismo brasileiro.

The dissertation examines the influence of relationships among actors from Brazilian Tourism Political Network who compose the National Council of Tourism in the drafting of the National Tourism Plans (PNT) - PNTs 2003/2007 and 2007/2010, focusing on two main types of interaction: cooperation and information exchange. Therefore, the study departed from the understanding that the concept of tourism as a human phenomenon is configured as an essential conceptual basis for the development, implementation and analysis of public policies. The application of Network Theory and Social Network Analysis serves as an analytical tool, in addition, the use of concepts of Policy Networks enabled to interpret, in distinct aspects, the social reality of tourism in a more precise and detailed way. The study had a cross-sectional with a longitudinal perspective and case study was adopted, thus enabling to apply the model of social network analysis and qualitative approach. Through the survey conducted, it was found that the drafting process of National Tourism Plans was the result of the interaction of a complex network of actors from public and private initiatives, who compose the National Council of Tourism, and that their power of influence came out simultaneously, but not symmetrically, for both their performance/intervention in the meetings, and the possession of economic and organizational resources. Hence, the establishment of partnerships and information exchanges among the actors were underlying to the PNT drafting process, both in problems perception and insertion in the government agenda, as in making proposals to solve them, thus guiding the construction of large programs and programs contained in both investigated plans.

Compostagem dos resíduos da produção avícola: cama de frangos e carcaças de aves

O propósito deste trabalho foi avaliar a eficiência do processo de compostagem no tratamento e na reciclagem dos resíduos cama de frangos e carcaças de aves. Para tanto, o material foi disposto na composteira em camadas alternadas de cama de frango por 60 dias (pré- -compostagem), tempo necessário para que ocorresse a decomposição prévia das carcaças e assim fosse possível manipular o material e confeccionar as leiras de compostagem. Posteriormente, o material pré-compostado foi transferido para o pátio de compostagem, onde foram avaliados: peso, número mais provável (NMP) de coliformes totais e termotolerantes, sólidos totais (ST), temperatura, pH e os teores de N, P, K, Ca, Na, Mg, Fe, Zn e Cu. Foram observadas reduções elevadas de ST e principalmente de N, que durante a fase de compostagem chegou a 71,6% de perdas. Com relação ao NMP de coliformes totais e termotolerantes, as reduções chegaram a 100%. A compostagem de carcaças e cama de frangos demonstrou ser um método eficiente para o tratamento e o aproveitamento desses resíduos.

Biodigestão anaeróbia dos resíduos da produção avícola: cama de frangos e carcaças

O propósito deste trabalho foi avaliar a produção de biogás, bem como os potenciais de produção e a qualidade do biofertilizante obtido com a biodigestão anaeróbia dos resíduos cama de frangos e carcaças de aves pré-compostados. Para tanto, foram pré-compostados cama de frango e carcaças de aves mortas em uma composteira durante um período de 60 dias, período necessário para que ocorresse decomposição prévia das carcaças e assim fosse possível manipular o material para abastecer os biodigestores. Após este período, o material foi utilizado para abastecer os biodigestores batelada de campo com capacidade de 60 litros de material em fermentação. Para o processo de biodigestão anaeróbia, foram efetuadas análises dos teores de sólidos totais (ST), sólidos voláteis (SV), composição química do efluente, potenciais de produção, além do número mais provável (NMP) de coliformes totais e termotolerantes no afluente e efluente. Os potenciais médios de produção de biogás foram: 0,073; 0,152 e 0,141m³.kg-1 de material, SV e ST adicionados, respectivamente. Foram observadas reduções acima de 99% no NMP de coliformes totais e termotolerantes, sendo observado NMP de 3,7 x 10(5) g-1 no início e 7,45 x 10² g-1 no final.
