Problemas de agência no setor público: o papel dos intermediadores da relação entre poder central e unidades executoras

Este estudo teve como objetivo central identificar de que forma a alocação de indivíduos como intermediadores das relações de agência impacta os conflitos inerentes à relação principal-agente no âmbito da administração pública. Para tanto, foi considerado o contexto do arranjo contratual existente entre o Escritório de Gerenciamento de Projetos da Secretaria Municipal da Casa Civil (CVL/EGP-Rio), representante do poder central da Prefeitura da Cidade do Rio de Janeiro, e os órgãos e entidades executoras dos projetos e metas estratégicos definidos por esse poder central. A revisão bibliográfica apontou a existência de quatro problemas de agência principais, os quais dizem respeito às diferenças de motivações e objetivos, às assimetrias de informação, às distintas propensões ao risco e aos diferentes horizontes de planejamento. Foram realizadas dez entrevistas semi-estruturadas com ocupantes do cargo de Analista de Gerenciamento de Projetos e Metas (AGPM), que atuam como intermediadores da relação de agência entre CVL/EGP-Rio e unidades executoras. Os resultados do estudo indicam que o intermediador da relação de agência analisada é capaz de provocar redução naqueles conflitos de agência relacionados com as diferenças de motivações e objetivos e com as assimetrias de informação. Quanto aos problemas de agência que dizem respeito às distintas propensões ao risco e aos diferentes horizontes de planejamento, a pesquisa demonstra que o intermediador não promove qualquer impacto, seja no sentido de acentuá-los ou atenuá-los.

Caracterização Microestrutural e Tribocorrosiva de Sistemas Metalocerâmicos Odontológicos do Tipo Ni-Cr/Porcelana E Ni-Cr/Ti/Porcelana

The partial fixed prosthodontics restoration is used to rehabilitate form and function of partial or total compromised teeth, having to remain permanently joined to remainder tooth. The most useful material on prosthodontics is the feldspar porcelain, commercialized as aluminosilicate powders. Dental porcelains are presented with limited mechanical properties to rehabilitate extensive spaces. The association with Ni-Cr metallic systems (metal-ceramic system) allows that the metallic substructure compensates the fragile porcelain nature, preserving the thermal insulation and aesthetics desirable, as well as reducing the possibility of cracking during matication efforts. Cohesive flaws by low mechanical strength connect the metallic substructure to the oral environment, characterized by a electrolytic solution (saliva), by aggressive temperature, pH cyclic changes and mechanical requests. This process results on ionic liberation that could promote allergic or inflammatory responses, and/or clinical degradation of ceramometal system. The aim of this study was to evaluate the presence of an intermediate titanium layer on the microscopic fracture behavior of porcelains on ceramometal systems. Plasma deposition of titanium films result in regular passivating oxide layers which act as barriers to protect the metallic substrate against the hazardous effects of corrosive saliva. Tribocorrosion tests were performed to simulate the oral environment and mechanical stress, making it possible the early detection of crack formation and growth on metal-ceramic systems, which estimate the adherence between the compounds of this system. Plain samples consisting of dental feldspar porcelain deposited either onto metallic substrates or titanium films were fired and characterized by scanning electron microscopy. The result showed that the titanium film improved the adherence of the system compared to conventional metal-ceramic interfaces, thus holding crack propagation

A teoria democrática e a participação popular : as trajetórias participativas no Recife e em Módena

This work basically achieve three goals. Critically investigate the liberal democratic regime and its historical reformulation, rejecting the popular power and popular self-organization, limiting the entry of normal citizen in decision-making, believing in the market as a mediating body in regulating of the different life spheres of social. Starting from the critical liberal democracy, it discussed the concept of popular participation in the democracy, searching new democratically horizons, where the masses could have the opportunity to make decisions about their own destiny. On the basis of theoretical discussion on participation, we discuss a concrete instrument of participation, the Participatory Budgeting, comparing two participatory experiences in North and South

Canções no ensino de sociologia: reflexões e aplicação

As Sociology becomes a mandatory subject in the curricular componentof Brazilian high schools, we find anopportune moment to proposals and changes in the subject and in teaching, in a general aspect. It s noticed the great importance of the role that the create imagination plays in individual s formation (BACHELARD), and it s also seen that Brazilian education system has marginalized imagination to the detriment of a unifocused scientism that sterilizes creativity, playfulness and poetry in its educational process. Nevertheless, a way of thinking redefinitions to the educational horizons of Sociology as a subject and education is upheld. An educational practice that reconnects the prosaic and the poetic, using images/songs as paths/strategies of the teaching-learning process. As for that, the school structure was used where the tutor work was done to undertake experiences that made the use of songs as strategy to facilitate/stimulate the learning of the subject Sociology in high school. From thoughts and results of this experience, plus the bibliographic studies, analysis were made. The goal of this essay is to make use and stimulate the creation of poetic images from the teaching point of view, specially the Sociology subject in high school, rethinking and searching more efficient and playful ways of approaching and building educational methods from images; stimulating the development of the Thinking Reform and the Anthropoetics of the human gender (MORIN); acknowledging that imagination is an indispensable part of our integral formation

Alguns aspectos sobre o processo da democratização dos sistemas políticos no mundo árabe :Egito e Líbano como modelos de estudo

The World has tried diverse democratic waves at distinct moments. Some nations have adopted the idea of the democracy for years; others have not yet and other ones are still in a slow process of transition. The field of studies on the Arabian political systems has testified since the last quarter of 20th century a notorious development. This advance disclosed in the existence of a set of trends that has turned around a number of concepts and main theoretical frames such as the political pluralism and the democratic transition and the civil society and its relation with the State. The speech on the process of democratic transition consists in part in the capture and the analysis of the role of the forces and the organizations of the civil society in this process. The peculiarities of the Arab World excite questions concerning the establishment of one governmental system in this universe in the mold of that one that develops with hegemony in the Occident, which has become an interesting field of inquiries for the Political Science. This study comprises the analysis of some aspects of the political situation in the Arab World towards the process of democratization in which Egypt and Lebanon are models of study. Thus the theoretical basis of the term democracy is introduced, presenting different considerations about this expression, since the sprouting of the term until its current conception; later the civil society is analyzed as well as the systems of the political parties and the electoral systems of both countries in attempt to identify the level of democratization existing there and also to find the possible ways to magnify the democratic horizons

Duas mãos e o sentimento do mundo: Hélio Vasconcelos

This thesis deals with the intellectual itinerary of the humanist, lawyer and educator RN Helio Vasconcelos in building a more cohesive society, just and egalitarian, less marked by inequality, by poverty, ignorance and lack of freedom of his people suffered and loved. It also shows, as after suffering the hardships caused by the political persecution and imprisonment, exile faced with dignity, developing an exemplary job of defending the rights of children and adolescents. For this, redo the way that intellectual humanist, simple man who never gave up their way of thinking, of viewing the world, to love and respect all that surrounds him, thinking globally and acting locally, always holding the defense Rights human. Helium shows how solidarity exercised intensely and as bothered with the real interests of the community to hold public office. It seeks to demonstrate the need for reformulation of Legal Education in order to stimulate the formation of a lawyer gifted humanist profile

Liberdade de expressão artística: concepções filosóficas, fundamentalidade constitucional e política da pluralidade

The right to artistic expression, freedom granted in the western democratic constitutionalism, is a fundamental right that cyclically, compared to other cohesive rights of expression, has been forgotten and put in an irrelevant juridical-dogmatic position. The first reason for this behaviour that disesteems artistic freedom is the valorisation of rationalism and scientificism in the modern society, subordinating academic researches to utilitarianism, relegating the purpose of feelings and spirituality on men s elocution, therefore, we investigate, guided by philosophy, the attribution of art on human formation, due to its capacity in harmonising reason and emotion. After that, we affirm the fundamental right to artistic expression s autonomy in the 1988 valid constitutional order, after a comparative explanation of freedom in the Fundamental Laws of United States, Portugal, Spain and Germany; and the construction historic-constitutional of the same right in the Brazilian Constitutions. In this desiderate, the theoric mark chosen is the Liberal Theory of the fundamental rights, guiding the exam through jusfundamental dimensions: juridical-subjective and juridical-objective. Whilst the first, classical function of resistance, delimitates the protection area of the artistic expression right from its specific content, titularity and its constitutional and subconstitutional limits, the other one establishes it as cultural good of the Social Order, defining to the State its rendering duties of protection, formation and cultural promotion. We do not admit artistic communication, granted without legal reserve, to be transposed of restrictions that belong to other fundamental rights and, when its exercise collides with another fundamental right or juridical-constitutional good, the justification to a possible state intervention that tangentiates its protection area goes, necessarily, through the perquisition of the artist s animus, the used method, the many viable interpretations and, at last, the correct application of the proportionality criteria. The cultural public politics analysis, nevertheless, observes the pluralism principle of democratic substratum, developer of the cultural dialogue and opposed to patterns determined by the mass cultural industry. All powers are attached, on the scope of its typical attributions, to materialise public politics that have the cultural artistic good as its aim, due to the constant rule contained in §1, art. 5º of the Federal Constitution. However, the access and the incentive laws to culture must be constantly supervised by the constitutional parameter of fundamental right to equality

Uma educação tecida no corpo

In theory say the education as a knot of meanings made in the body. We take as a reference for demonstration of this argument the shows Folguedos, Guarnicê and Flor do Lírio and built within such spectacles cultural, symbolic and aesthetic meanings, which reveal the education woven in the body. Education that can happen not only in the formal space like the classroom or the university, but also in the area of art and the inclusion of individuals in the world of culture. So during the construction of the thesis we reflect on the following issues: what is the construction of culture and art that have in the Parafolclórico group? What way theses shows in their buildings bring significant elements that might compose an educational activity. How objectives sought asking the dichotomies present in the concepts of art and culture; critically systematize a work of artistic, cultural and educational production in the group, in addition to expanding the understanding of education, considering the body experiences. The phenomenological attitude of Merleau-Ponty, is a reference methodology of this study, which places the reference knowledge as a result of our experience in the world, our world lived. Thus, this study considers the experience of the researcher in the three shows in tariff, represented by scenes described, as a dancer and spectator. Therefore we understand that Folguedos, Guarnicê and Flor do Lírio in their artistic, aesthetic and cultural languages, allow many meanings that occur in the body, which invites the perception and extend the experience of the subject, demonstrating an education that allows sight and knowledge, seeking new sensations and experiences, we show our intimacy with the world, with the objects and with the other. The art is understood as virtuality, as a human creation that carries the reality and that allows many readings and experiences, each perception can recognize and know new horizons, having as base and material the culture. This entails the heterogeneous, is not closed but that individuals can interpret it entered and recognize the symbols they created the same way, confirming a unit. The art and culture show us significant evidences of an education woven in the body

É como se tivesse a roça e faltasse a enxada: formação em serviço de professores de História no ensino sergipano

This thesis has the aim to comprehend the development of the superior graduation in life service and daily scholar of the history teachers in-land of Sergipe. The History Course graduation was realized through the second part of (Projeto de Qualificação Docente-PQD), the so-called, Teaching Qualification Project of the Federal University of Sergipe, first settled in 1998. Eight teachers were chosen for this research with more than (15) fifteen years of teaching in the Fundamental and Medium levels at public schools of our state (Sergipe). This empiric research priviledged oral testimony from them, which (ones) reveled about the memory tragetory of life. Since childhood until the History Course graduation, besides the evidence as Principal of schools as well as the following classes. All of them were interviewed from in-land and they are from very poor families with lack of social economical conditions. Those evidencies point out economic limitations in their different towns, that contributed to the continuous obstacle in the following studies, moreover in the common market. Therefore they still teach in order to believe in who´s at the botton of this business. Their testimony about this history graduation through PQD , gave them new Professional horizons, modifying their pedagogic practice, choosing what is worth into the social space beyond life expectancy. Through the analyses from all the documents and evidence in loco, it was evident that this graduation is not sufficient to change all the acting of teaching. Consequently, the lack of scholar situation still happens because this qualification doesn´t consider the knowledge of the teachers into their contexts. This research could also observe that besides the changing purposes in the suggested common-job by the globalization, the public politics education, is still underdeveloped in-land of Sergipe. According to the educational laws which obliges all tearches should be graduated, it could be observed that nothing changed into their acting. The old curricula don´t give them new possibility in their acting. At last their salaries, poor conditions in their common-job as well as the difficult ways to get to their pos graduation course still contributes to the underdeveloped acting before they´d graduated from the period before of their graduation

Superfícies geomórficas e atributos de Latossolos em uma seqüência Arenítico-Basáltica da região de Jaboticabal (SP)

Em um segmento de vertente com substrato de arenito em contato com basalto, regionalmente muito freqüente, pretendeu-se não só relacionar as superfícies geomórficas com os atributos físicos, químicos e mineralógicos dos Latossolos nelas encontrados, mas também testar métodos geoestatísticos para localização de limites dessas superfícies. Usando critérios geomorfológicos, três superfícies foram identificadas e topograficamente caracterizadas. Os solos foram amostrados, a intervalos regulares de 25 m, na profundidade de 0,6 a 0,8 m (topo do horizonte B), em uma transeção de 1.700 m perfazendo 109 pontos. Nas amostras, foram analisados: densidade de partículas, granulometria, CTC do solo, CTC da argila, Fe total da argila (ataque por H2SO4) e óxidos de Fe livres (por dissolução seletiva). A fração argila desferrificada foi analisada por difração de raios X. Com base na estratigrafia e variações do relevo local, foram identificadas e diferenciadas, no campo, três superfícies geomórficas. Analisaram-se também o perfil altimétrico e o modelo de elevação digital do terreno. Observou-se que as três diferentes superfícies estão bem relacionadas com os atributos físicos, químicos e mineralógicos dos seus respectivos solos. Na parte inferior desta vertente, superfície mais recente e sobre basalto, em Latossolo Vermelho eutroférrico típico, foram encontradas as maiores variabilidades da declividade, da argila e de Fe. As variações da inclinação do terreno, quando analisadas sistematicamente pelo split moving windows dissimilarity analysis (análise estatística de dissimilaridade, em segmentos móveis), mostraram que este método estatístico pode ser usado para ajudar a localizar os limites entre superfícies geomórficas. As variações dos solos da transeção, e arredores, mostraram-se relacionadas com idade, inclinação do terreno e litologia. O trabalho geomórfico detalhado forneceu importantes informações para subsidiar os trabalhos de levantamento de solos e de pedogênese.

Caracterização mineralógica de Latossolos em diferentes feições do relevo na região de Jaboticabal, SP

Different surface land form expressed by the relief can cause variations in soil properties in different magnitudes, depending mainly on a specific location in the landscape. Therefore, the objective of this study was to make the mineralogical characterization of Oxisols in different relief forms in the region of Jaboticabal, SP. Three trenches were opened in the convex, linear and concave landforms, done morphological description of the soil horizons and collected soil samples for physical, chemical and mineralogical characterization. It was found that the oxidic mineralogy is dependent on the type of landform, with the dominance of goethite on the concave landform and hematite on the linear landform. The desferrific clay minerals exhibited dominance of gibbsite in the concave, compared to convex and linear landforms that were dominated by the kaolinitic mineralogy.

Viabilidade técnica de uma rota não convencional para a produção de leite de cabra em pó em cooperativas do Rio Grande do Norte

Nowadays, Brazil has both the greatest goat herd and the greatest goat milk production of South America. The state of Rio Grande do Norte, located in northeast of Brazil, has an average year production of three thousand cubic meters of goat milk in natura. Part of this milk production is homemade and it comes from small farms, which unite in rural cooperatives created to encourage the production and implementation of industrial processes for preservation and processing of milk. Results presented by literature and obtained from preliminary essays in this thesis show that non conventional dryer of spouted bed with inert particles is able to produce powder milk from in natura milk (cattle or goat), with the same quality of spray dryer, however, operating at low cost. The method of drying in spouted bed consists of injecting milk emulsion on the bed of inert particles gushed by hot air. This emulsion covers the particles with a thin film, which dries and is reduced to powder during the circulation of inerts inside the bed. The powder is dragged by exhaustion air and separated in the cyclone. The friction among particles resulted from the particles circulation, encourages high taxes of shear in the thin film of emulsion, breaking the cohesive forces and making this process possible. Studying the drying process and the powder goat milk production in one unit of spouted bed with inert particles, seeing the development of a low cost technological route for powder milk production is the aim of this thesis. The powder milk produced by this route must attend the local demand of food industries which need an intermediate product to be used as a food ingredient (ice-cream, milk candy). In order to reach this aim, this thesis approaches the aspects related to physical, thermodynamics and physic-chemicals characteristics of goat milk, whose complete data are still inexistent in the literature. The properties of materials are of great importance to the project of any process which involves the operations of transportation of movement, heat and mass quantity, such as the dryers which operate in fluid dynamically active regime, like the spouted bed. It was obtained new data related to the goat milk properties in function of concentration of solids and temperature. It is also important to mention the study developed about the kinetic of solids retention in the bed of inert particles during the drying of goat milk. It was found more adequate processes conditions to the proposed technological route to be implemented in small and micro-industries, with simplifications in the system of milk injection as well as in the form of operation of the dryer. Important data were obtained for a posterior stage of this research which involves the v modeling, simulation, control and optimization of the process. The results obtained in this thesis, in relation to process performance as well as to the quality of produced powder milk validate the proposal of using the spouted bed dryer in the production of powder goat milk

Mecanismos de coesão referencial na produção escrita de alunos concluintes do ensino fundamental

This work aims to identify, describe and analyze the main mechanisms of reference present in the texts produced by students that are finishing their fundamental school. With this in mind, we observe 46 Portuguese classes. The class was in its 9th Fundamental level, in a public school of the Cruzeta, RN. In this period, we collected our corpus that is composed by the papers that students produced. This research has an ethnographic approach and it has as theoretical support some studies about some mechanisms of reference, specifically, the lexical repetition and anaphor. In general, we are based on the studies about cohesive mechanisms from authors as Adam (2008); Beaugrande and Dressler (1981, 1997); Koch (1999, 2004, 2005, 2008), Marcuschi (1983, 1992, 2005, 2006); Bessa Neto (1991) and Neves (2006). In the corpus, we could identify some lexical repetitions (literal, with estrutural variation), as well as, anaphors, mainly pronominal ones. Then, we can notice that most students have showed difficulties in the use of those mechanisms of reference as a strategy of textual progression

Fission-track dating of South American natural glasses: an overview

Although many glass-bearing horizons can be found in South American volcanic complexes or sedimentary series, only a relatively few tephra and obsidian-bearing volcanic fields have been studied using the fission-track (FT) dating method. Among them, the volcanics located in the Sierra de Guamani (east of Quito, Ecuador) were studied by several authors. Based upon their ages, obsidians group into three clusters: (1) very young obsidians, similar to 0.2Ma old, (2) intermediate-age obsidians, similar to 0.4- similar to 0.8 Ma old, and (3) older obsidians, similar to 1.4- similar to 1.6 Ma old. The FT method is also an efficient alternative technique for identification of the sources of prehistoric obsidian artefacts. Provenance studies carried out in South America have shown that the Sierra de Guamani obsidian occurrences were important sources of raw material for toot making during pre-Columbian times. Glasses originated from these sources were identified in sites distributed over relatively wide areas of Ecuador and Colombia.Only a few systematic studies on obsidians in other sectors were carried out. Nevertheless, very singular glasses have been recognised in South America, such as Macusanite (Peru) and obsidian Quiron (Argentina), which are being proposed as additional reference materials for FT dating. Analyses of tephra beds interstratified with sedimentary deposits revealed the performance of FT dating in tephrochronological studies. A remarkable example is the famous deposit outcropping at Farola Monte Hermoso, near Bahia Blanca (Buenos Aires Province), described for the first time by the middle of the 19th century by Charles Darwin.Considering the large number of volcanic glasses that were recognised in volcanic complexes and in sedimentary series, South America is a very promising region for the application of FT dating. The examples given above show that this technique may yield important results in different disciplinary fields. (c) 2005 Elsevier Ltd. All rights reserved.
