governo eletrônico como propiciador da reforma do estado: o caso do leilão reverso na web para licitação pública

A presente dissertação versa sobre o uso da Tecnologia da Informação e Comunicação aplicada aos processos de gestão pública à luz dos conceitos de eficácia, eficiência e accountabítlity. Para tanto, este estudo se funda sobre dois marcos teóricos. O primeiro trata do desenvolvimento científico-tecnológico e suas implicações na construção de uma sociedade resultante da interação da microeletrônica, da informatização e da telecomunicação. O segundo diz respeito à reforma do Estado Brasileiro, num contexto em que se discute a necessidade de torná-lo mais ágil, flexível e mais responsável perante a sociedade. Metodologicamente, valemo-nos do estudo de caso múltiplo, no qual analisamos o Pregão Eletrônico utilizado pelo Governo Federal para aquisição de bens e serviços nos moldes do leilão reverso do mercado de flores de Amsterdã. Especificamente, trata-se do Pregão 21/2001, realizado pelo Ministério da Previdência e Assistência Social, para compra de medicamentos. Este estudo contempla não só os diferentes aspectos do comércio eletrônico, como o procurement, mas também descreve o processo tradicional de licitações públicas. Ao final, concluímos que a adoção da tecnologia da informação aplicada à gestão pública, em especial como ferramenta para aquisição de bens e serviços, mostrouse eficiente ao promover uma redução de custos, tanto dos processos governamentais, quanto dos produtos adquiridos, fato extremamente relevante se considerarmos a realidade orçamentária brasileira. Ficou também comprovada a sua eficácia, evidenciada pela redução do tempo necessário à realização do procedimento, uma vez comparado ao processo tradicional de licitações pública. Por outro lado, podemos afirmar que a iniciativa amplia o grau de transparência das informações do setor público brasileiro, reconfigurando as relações EstadoSociedade.

A evolução histórica da formação do professor de 2. grau nas Faculdades de Educação ou unidades equivalentes

A educação vem sofrendo graves, permanentes e contundentes críticas quanto a sua produtividade, eficácia e eficiência. O ataque sistemático às escolas, e em especial às destinadas à preparação de professores, e uma constante em países do Velho, do Terceiro e do Novo Mundo. Todos concordam que a função docente exige competência profissional, sendo a sua ausência a principal responsavel pelas lacunas, insuficiências e deficiências do processo educacional. Acredita-se que a situação ensino-aprendizagem proporcionada por uma atividade didática bem orientada seja um fator de suma importância para a eficácia e eficiência de um sistema de ensino. Considerando a expansão do ensino de 2o grau, que o levou a perder muito do seu caráter acadêmico e seletivo, optou-se pelo estudo da formação do professor que a ele se destina. Com a finalidade de verificar o tipo de formação que o professor de 2o grau vem recebendo e as consequências deste no seu desempenho profissional. Analisa-se criticamente a evolução histérica de sua formação, no Brasil, e procede-se a um estudo dos currículos dos cursos de licenciatura das Faculdades de Educação, ou Unidades Equivalentes, do Estado do Espírito Santo. Verifica-se que estas, de modo geral, adotam o currículo mínimo proposto pelo Conselho Federal de Educação. Sabe-se que o ensino de 2o grau, atualmente, destina-se a alunos provenientes das mais diversas classes sociais, sendo os seus objetivos bem mais amplos que antes verifica-se que as alterações curriculares limitam-se a uma improdutiva ampliação ou diminuição de carga horária e de disciplinas. Deduz-se que a Faculdade de Educação não trouxe nenhuma inovação significativa no que concerne ao currículo de formação pedagógica de professor de 2o grau,o que dá procedência às críticas negativas que a mesma vem recebendo. Recomenda-se a realização de pesquisas de campo e o estudo de propostas curriculares objetivando obter subardias para a reformulação dos currículos atuais.

Avaliando o avaliador: evidências de um experimento de campo sobre as auditorias da CGU

O Brasil praticamente alcançou a provisão universal dos serviços públicos de educação, saúde e assistência social nos últimos anos, mas a qualidade desses serviços ainda está bem atrás da maioria dos países desenvolvidos. As instituições de controle são atores relevantes nesse contexto, pois é seu dever avaliar a efetividade e a eficiência da provisão desses serviços públicos. Entretanto, pouco se sabe sobre a efetividade dessas instituições, especialmente no Brasil. Os artigos de Olken (2007), Reinikka e Svensson (2004) e Di Tella & Schargrodsky (2000) trazem alguns elementos para essa discussão, ao mostrar como e onde políticas de boas práticas podem funcionar em outros países. No Brasil, estudos empíricos sobre essas políticas são escassos. Nesta tese, meu principal objetivo é trazer evidências sobre a efetividade da auditoria pública no Brasil. Utilizando um experimento de campo, eu avalio a efetividade do trabalho de auditoria da Controladoria-Geral da União (CGU) no âmbito do Programa de Fiscalização a partir de Sorteios Públicos. Os principais tópicos discutidos aqui são relativos à gestão de programas em nível local e aos processos licitatórios a eles associados. Os municípios no grupo de tratamento são submetidos a um aumento na probabilidade de receber uma auditoria, enquanto os de controle permanecem com probabilidade inalterada. Os resultados sugerem que os gestores locais são sensíveis ao tratamento quando focamos as licitações, mas não quando a questão é a gestão de programas. Em seguida ao experimento, utilizo um modelo "Fora da Amostra" para sugerir um mecanismo de alocação de recursos financeiros e humanos, para melhorar os níveis de eficiência do trabalho de campo da CGU

Relações civis-militares e política de defesa na Argentina (1983-2013)

Nos últimos anos foi grande a evolução do estudo das relações civis-militares e seus reflexos para a elaboração das políticas de defesa das nações. Neste contexto, o presente estudo discutiu a evolução das relações civis-militares e da política de defesa da Argentina nos governos democráticos do período de 1983 a 2013. Foi demonstrada a forte influência exercida pelo controle civil sobre os militares na elaboração e na implementação da política de defesa argentina fato que pode ter redundado na perda considerável de efetividade do instrumento militar do país. Foram verificados também, os aspectos positivos e negativos das políticas de defesa planejadas e implementadas pelos sucessivos governos do período. Por último, observou-se a necessidade da utilização dos modernos conceitos de efetividade e de eficiência com o objetivo de melhorar a qualidade da política de defesa do Estado Argentino.

Desenvolvimento e assistência social : uma avaliação da efetividade da política de assistência social nos municípios de Assú e Mossoró (2004 -2008)

This thesis, whose title is DEVELOPMENT AND SOCIAL ASSISTANCE: AN EFFECTIVENESS EVALUATION IN SOCIAL ASSISTENCE POLICY IN THE CITIES OF ASSÚ AND MOSSORÓ/RN (2004/2008), has as main aim to evaluate effectiveness in Social Assistance Policy in the cities of Assu and Mossoró/RN, from 2004 to 2008, identifying its impacts and effects in life of its users. The methodological process for the research was composed by: a) Literature review on this theme, development of public policies; social public policies, public policy evaluation and Social Assistance Policy in Brazil; b) Documental research from Municipal Management of Social Development and Municipal Counsels of Social Assistance in the cities of Assu and Mossoró/RN about the object of this study and empirical field; c) Field Research constituted by the realization of Focal Groups with Social Assistance users and semistructured interviews with municipal managers from Assú and Mossoró. It was also taken into account participant observations in events and activities related to Social Assistance previously mentioned, considering field management and also the response to users demands. Articulating the themes of Development and Public Social Policy in Social Assistance was the theoretical purpose for this thesis. To achieve this purpose, it was performed two theoretical displacements related, at the same time, to the notion of development and to the concept of Social Assistance, which means to comprehend development as social change and improvement in users life quality, expressed in the expansion of their capacities and liberties (SEN, 1993, 2000), and the Social Assistance as an element for development. Such displacements provide a view of Public policy and Social Policies and evaluate National Policy of Social Assistance achieved in those cities. As product, this thesis presents a methodological purpose for effectiveness evaluation in Public Policy, taking into account expansion of capacities and liberties, concluding that Social Assistance Policy in Assú and Mossoró/RN, even in lesser extent had its impact and caused effective results in the life of their users and provided an expansion of their capacities and liberties, improving life quality and empowered agent condition for those subjects. The results show that this Policy has been proved to be effective, and consequently, it was considered, in this thesis, to be also an element and an allied for development

Biological control of Bradysia matogrossensis (Diptera : Sciaridae) in mushroom cultivation with predatory mites

Larvae of Sciaridae flies (Diptera) cause considerable damage to the mushroom Agaricus blazei (Murrill) ss. Heinemann in Brazil. Brazilian growers have had considerable difficulties in controlling this pest. The objective of this work was to test the effect of the predatory Laelapidae mite Stratiolaelaps scimitus (Womersley) as a control agent of Bradysia matogrossensis (Lane) in cultures of A. blazei. The work corresponded to an evaluation of the efficiency of that predator when released in boxes containing each about 15 L of commercial mushroom compost naturally infested with the pest. The results showed a significant effect of that predator on the population of B. matogrossensis. The release of either 665 or 1330 S. scimitus per box significantly reduced the pest population to levels that, according to grower's experience, apparently could not cause considerable damage. The positive results obtained warrant the conduction of complementary studies to determine the lowest rates of the predator that could still produce acceptable levels of control.

Germinação de sementes de alface submetidas a condicionamento osmótico durante o armazenamento

Em algumas espécies a técnica do condicionamento osmótico permite a obtenção de uma germinação rápida e uniforme. A pesquisa teve por objetivo verificar a eficiência do condicionamento osmótico de sementes de alface sobre a sua germinação. Sementes dos cultivares Mesa 659, Nabuco RS e Verônica, com dois níveis de viabilidade, foram submetidas ao condicionamento osmótico em solução (0,35 mol) de manitol por períodos de 3, 4, 5 e 6 dias sob 20ºC e em presença de luz. A seguir, as sementes foram submetidas à secagem (32ºC) por 12 horas em estufa com circulação de ar. As avaliações foram feitas pelo teste padrão de germinação aos 0, 10, 20, 30, 60 e 90 dias após o condicionamento e secagem das sementes. Utilizou-se o delineamento experimental inteiramente casualizado, com quatro repetições de 50 sementes, em esquema fatorial 2 × 5× 6, (dois níveis de vigor; cinco períodos de condicionamento osmótico e seis períodos de armazenamento após secagem). A resposta de sementes de alface ao condicionamento osmótico varia em função do cultivar e do período de condicionamento osmótico.

Teste de envelhecimento acelerado para avaliação do potencial fisiológico de sementes de grama-bermuda

A utilização de sementes para formação de gramados esportivos e ornamentais tem assumido grande importância no Brasil, principalmente pelo baixo custo em relação à formação por placas de tapetes naturais. As bermudas [Cynodon dactylon (L.) Pers] são as principais gramas utilizadas na formação de campos esportivos e, dentre os problemas enfrentados, destaca-se a dificuldade de estabelecimento adequado da cultura, fato que exige a utilização de sementes de alto potencial fisiológico, de modo a permitir rápida emergência e desenvolvimento das plantas. Assim, estudaram-se procedimentos para a condução do teste de envelhecimento acelerado para determinar o potencial fisiológico de sementes dessa espécie, incluindo a avaliação da eficiência do uso de solução saturada de NaCl como alternativa para a realização do teste. Para tanto, cinco lotes de sementes foram submetidos aos testes de germinação, emergência de plântulas e envelhecimento acelerado (períodos de 48, 72 e 96 h, a 41 e 45 ºC, com e sem o uso de solução saturada de NaCl). O experimento foi conduzido em delineamento inteiramente casualizado. O envelhecimento acelerado com o uso de solução saturada de NaCl, dentre os procedimentos estudados, é o método mais adequado para avaliação do potencial fisiológico de sementes de grama-bermuda, sendo que a combinação 45 ºC/48 h é eficiente para a classificação dos lotes em diferentes níveis de vigor.

Análise comparativa entre propriedades mecânicas, termofísicas e geométricas de tijolos produzidos pelos fornos caieira e abóbada

In the State of Rio Grande do Norte potteries are distributed in several counties in the four meso, which are: West Potiguar, Center Potiguar, Agreste Potiguar and East Portiguar. The ceramics, mostly, are responsible for products used in construction as bricks, tiles and white brick and wood used as fuel. This paper had a primary focus in the region of Seridó. The furnaces in this region, used to manufacture bricks are configured Caieira and Valt, in most of them using principles rustic, usually operated in an empirical way, using principles of control rather primitive, predominantly visual control. The focus of this study was to analyze the differences in the thermophysical, mechanical and geometric characteristics of bricks produced by Caieira and vault furnaces, using the NBR 15720 and the evaluation of energy efficiency in both furnaces. Thermophysical characteristics were analyzed through tests to determine the water absorption obtained from the difference between dry mass and wet mass of the sample and analysis of the thermal gradient, the mechanical characteristics from determination of the compressive strength of ceramic brick popularly known as bricks and also analyzed the geometrical characteristics of the bricks in order to verify the homogeneity of manufacturing. The tests showed that the energy difference of the two furnaces is not considered responsible for a significant difference in the properties of the products

Avaliação da eficiência de catalisadores comerciais na obtenção de biodiesel de algodão (Gossipium hisutum L.)

The increasing demand for energy and the environment consequences derived from the use of fossil energy, beyond the future scarcity of the oil that currently is the main power plant of the world, it stimulated the research around the production of biodiesel. In this work the synthesis of biodiesel of cotton in the methyl route was carried through, for had been in such a way used catalyst commercial homogeneous, Na-Methylat and the K-Methylat, aiming to the evaluation of the efficiency of them. An experimental planning 23 was elaborated aiming to evaluate the influence of the variable (molar reason oil/alcohol, % of catalyst and temperature) in the process as well as indicating the excellent point of operation in each case. The biodiesel was analyzed by gaseous chromatography, indicating a conversion of 96,79% when used Na-Methylat® as catalytic, and 95,65% when the K-Methylat® was used. Optimum result found with regard to the conversion was obtained at the following conditions: molar reason oil/alcohol (1:8), temperature of 40°C and 1% of catalyst Na-Methylat, reaching a 96,79% conversion, being, therefore, above of the established for the European norm (96.5%). The analysis of regression showed that the only significant effect for a confidence level of 95%, was of the changeable temperature. The variance analysis evidenced that the considered model is fitted quite to the experimental response, being statistically significant; however it does not serve inside for make forecasts of the intervals established for each variable. The best samples were analyzed by infra-red (IR) that identified the strong bands of axial deformation C=O of methylic ester, characterized through analyses physicochemical that had indicated conformity with the norms of the ANP, that with the thermal and rheological analyses had together evidenced that biodiesel can be used as combustible alternative in substitution to diesel

Estudo de sistemas microemulsionados utilizando água do mar na recuperação avançada de petróleo

Petroleum exists in the nature in certain underground formations where it is adsorbed into the rocks pores. For the conventional recovery methods usually only 30% of the oil is extracted and this can be credited, basically, to three aspects: high viscosity of the oil, geology of the formation and high interfacial tensions between the reservoir s fluids. The enhanced recovery methods use the injection of a fluid or fluids mixture in a reservoir to act in points where the conventional process didn't reach the recovery rates. Microemulsion flooding, considered an enhanced method, has the purpose to desorb the oil from the rock formation and to attain an efficient displacement of the oil emulsion. With this in mind, this work was accomplished with two main objectives: the study of the parameters effect that influence a microemulsified system (surfactant and cosurfactant types, C/S rate and salinity) and the evaluation of displacement efficiency with the microemulsions that showed stability in the rich aqueous area. For the analyzed parameters it was chose the microemulsions composition used in the recovery stage: 25% water, 5% kerosene, 46.7% of butanol as cosurfactant and 23.3% of BC or SCO cosurfactant. The core plugs of Assu and Botucatu sandstones were appraised in porosity and permeability tests and then submitted to the steps of saturation with seawater and oil, conventional recovery with water and enhanced recovery with the selected microemulsions. The Botucatu sandstone presented better recovery parameters, and the microemulsion composed with BS surfactant had larger recovery efficiency (26.88%)

Avaliando a aprendizagem de língua inglesa em uma escola de ensino médio a partir de contribuições discentes

This study discusses the evaluation of the English language‟s learning developed in a public high school from Lajes-RN in 2011 starting from a qualitative evaluation proposal (SAUL 1988; CANAN, 1996; DEMO, 2008) aiming the production of knowledge about the evaluation process developed in the classes of English language involving the contributions from students. To diagnose and characterize the evaluation process of English language of the researched school, identifying the representations that students attributed to the evaluation, we have implemented the evaluation instruments suggested by students to perform the evaluation of language learning and allowed a reflection about the student‟s participation in the construction of the evaluation process of the English language, subject discussed by Sant‟anna (2002) and other theorists (CANAN, 1996; BRAZIL, 2002; PEREIRA, 2009). To conduct the research work, we use the qualitative approach with ethnographic basis, substantiate in authors like Bogdan, Biklen (1994), Mazzotti; Gewandsznajder (1998), Strauss, Corbin (2008) among others. The methodology was the action research (ANDRÉ, 1995; NUNAN, 2007; LANKSHEAR; KNOBEL, 2008) described as research of empirical basis which associates an action with a resolution of a collective problem, because in it, its researchers and employees are engaged in a cooperatively way (THIOLLENT, 1985). When we treat about the evaluation of English language‟s learning (ALMEIDA FILHO, 1993; SCARAMUCCI, 2009) practiced before and after the contributions made by the students of the second year of the refereed school, the study considers that high school students have a more critical and reflective conscience with regard to their evaluations, not just opining on the assessment of learning English but also about the assessment of other subjects from their scholar curriculum and so this research presents possibilities for performing the act of evaluation which consider the participation of students in decisions regarding this process, because we cogitate that when the teachers share the decisions with their students, teachers can add quality to the evaluation process

Brazilian Students and Working Capital: An Analysis of Their Decisions When Using Virtual Market Business Games

This study aims to demonstrate that data from business games can be an important resource for improving efficiency and effectiveness of learning. The proposal presented here was developed from preliminary studies of data from Virtual Market games that pointed the possibility of identifying gaps in learning by analyzing the decisions of students. This proposal helps students to refine their learning processes and equips tutors with strategies for teaching and student assessment. The proposal also complements the group discussion and/or debriefing, which are widely used to enhance learning mediated by games. However, from a management perspective the model has the potential to be erroneous and miss opportunities, which cannot be detected because of the dependence on the characteristics of the individual, such as ability to communicate and work together. To illustrate the proposed technique, data sets from two business games were analyzed with the focus on managing working capital and it was found that students had difficulties managing this task. Similar trends were observed in all categories of students in the study-undergraduate, postgraduate and specialization. This discovery led us to the analysis of data for decisions made in the performance of the games, and it was determined that indicators could be developed that were capable of indentifying inconsistencies in the decisions. It was decided to apply some basic concepts of the finance management, such as management of the operational and non-operational expenditures, as well as production management concepts, such as the use of the production capacity. By analyzing the data from the Virtual Market games using the indicator concept, it was possible to detect the lack of domain knowledge of the students. Therefore, these indicators can be used to analyze the decisions of the players and guide them during the game, increasing their effectiveness and efficiency. As these indicators were developed from specific content, they can also be used to develop teaching materials to support learning. Viewed in this light, the proposal adds new possibilities for using business games in learning. In addition to the intrinsic learning that is achieved through playing the games, they also assist in driving the learning process. This study considers the applications and the methodology used.

Tratamento do Centro de Atenção Psicossocial para usuários de álcool e outras drogas CAPSad II Leste Natal/RN : uma avaliação da efetividade

The treatment for abusive users of alcohol and other drugs suffered significant modifications until arriving to the psychosocial model that is used by Centro de Atenção Psicossocial CAPSad II Eastern Natal/RN (Psychosocial Support Center). That model appears starting from Brazilian sanitary and psychiatric reforms which are expressed in the principles and propositions of Sistema Único de Saúde SUS (Unique System of Health). The Psychiatric Reform meant a rupture with the mental hospital and hospital centered treatment pattern which was destined to the abusive users of alcohol and other drugs. The new proposal offers the universalization, democratization, regionalization and completeness of the actions in the field of mental health. It gathers a strictly interdisciplinary health staff. The purpose of this study is to evaluate the effectiveness of the treatment for abusive users of alcohol and other drugs offered by CAPSad II Eastern Natal/RN. The evaluation used, as priority, the qualitative social research through an evaluating study starting from the non-experimental model. The methodological process used different instruments of data collection: bibliographical and documental researches, systematic observations at CAPSad II Eastern Natal/RN and, mainly, the semistructured interviews (21) that were accomplished with the professionals, users and relatives of CAPSad II Eastern Natal/RN. The investigation showed the effectiveness of the service and, therefore, CAPSad II Eastern Natal/RN constitute itself as the main confronting strategy to the mental hospital and hospital centered treatment pattern of caring the abusive users of alcohol and other drugs

A comparative SEM study of smear layer removal by detergents and EDTA on the root surface

The present study performed an SEM evaluation of the efficiency of the following detergents on smear layer removal on the root surface: sodium lauryl sulphate, Plax, castor oil, and EDTA 24%. Sodium lauryl sulphate did not remove the smear layer and showed the worst results of all detergents tested. Plax and castor-oil detergents showed similar results represented by partial removal of the smear layer; these results were better than those obtained in the control (physiologic serum) and sodium lauryl sulphate groups. Neutral EDTA 24% was the most efficient detergent for smear layer removal.
