Modelo de decisão multicritério para seleções interciclo das universidades novas: estudo na Universidade Federal do Rio Grande do Norte

The discussions wherein develop proposals for university reform in Brazil include, among other things, the conception of the university titled "New University", whose structural origin comes from the bill of higher education reform and unification of the foundations of education European upper (Bologna process). At its core, the Bologna process has imposed a series of transformations, among which, the promotion of mobility, as a stimulus to interinstitutional cooperation to enable an better and bigger qualification of the students. Nevertheless, what we see is that this point is one of the main points made flawed by Brazilian institutions that have adopted this model of higher education. An example is the Bachelor of Science and Technology - BC&T, Federal University of Rio Grande do Norte - UFRN, where there are problems of the internal order, represented by the problem of the reusing of the disciplines, such also of external order, in cases of transfers interinstitutional. Because of this, and knowing that this is a typical problem in which multiple criteria are involved, the aim of this study is to propose a multicriteria model for selection of interciclo of the BC&T of the UFRN which addresses the issue of mobility. For this, this study was of exploratory and study case nature, use as tools of data collection, the bibliographic and documentary research, as well as semi-structured interviews. For the elaboration of the model, were used the five phases most commonly used in the modeling of problems in operational research in a sample of 91 students of BC&T. As a result, we obtained a model that addresses the issue of internal and external mobility of the school and that, moreover, was also more robust and fair than the current model of BC&T and also what is used in other courses of the UFRN, taking into consideration the expected results by the decision makers

Sinterização de Ce1-XEuXO2-(X/2) para aplicação como eletrólito sólido em células a combustível de temperaturas intermediárias

Given the environmental concern over global warming that occurs mainly by emission of CO2 from the combustion of petroleum, coal and natural gas research focused on alternative and clean energy generation has been intensified. Among these, the highlight the solid oxide fuel cell intermediate temperature (IT-SOFC). For application as electrolyte of the devices doped based CeO2 with rare earth ions (TR+ 3) have been quite promising because they have good ionic conductivity and operate at relatively low temperatures (500-800 ° C). In this work, studied the Ce1-xEuxO2-δ (x = 0,1, 0,2 and 0,3), solid solutions synthesized by the polymeric precursor method to be used as solid electrolyte. It was also studied the processing steps of these powders (milling, compaction and two step sintering) in order to obtain dense sintered pellets with reduced grain size and homogeneous microstructure. For this, the powders were characterized by thermal analysis, X-ray diffraction, particle size distribution and scanning electrons microscopy, since the sintered samples were characterized by dilatometry, scanning electrons microscopy, density and grain size measurements. By x-ray diffraction, it was verified the formation of the solid solution for all compositions. Crystallites in the nanometric scale were found for both sintering routes but the two step sintering presented significant reduction in the average grain size

Situações de Risco, Trabalho e Saúde de Imigrantes Brasileiros: representações sociais

This study searches in approaching diverse pertinent aspects to the immigration process that affects the countries of the European Union especially in Portugal. The works deriving from this research has its objective in: analyzing the risk, work and health in Brazilian immigrants residing in Lisbon, Portugal. As methodological way, we use the instruments: Test of Free Association of Words and half-structuralized interview.

Paulo Freire e a pedagogia do oprimido: afinidades pós-coloniais

The main objective of the present research is to reflect on the affinities between post-colonial theories - analytical perspectives directed toward the discussion of colonialism and its effects on the contemporary social fabric - and Brazilian educator, Paulo Freire‟s (1921-1997) Pedagogy of the Oppressed, written at the end of the 1960‟s. The study aims to make the argument that the present reflections on the featured work is an example of a post-colonial theoretical framework, delineating a critical modus operandi of colonialism, particularly in its cultural and epistemic dimensions, delineating a problematization of the processes of cognitive domination set, above all, by the European colonization of the Latin American continent, with the formation of the modern-world-system (WALLERSTEIN, 2007), dated from the 16TH Century forward. From this stand point, and especially supported by the contributions of Boaventura de Sousa Santos on the sociology of absence, the present work accentuates Pedagogy of the Oppressed as a set of reflections that bring the possibility of a pedagogy of absence (SANTOS, 1996), having in mind that, this book deals with, the presuppositions of an educational action, which considers the plurality of knowledge and social practices by way of the establishment of a pedagogical practice of collective construction, emancipator and dialogic that arises from the encounter to the indolent reason (SANTOS, 2009) in which the silencing of the voices of the oppressed, construct their conditions of invisibility, promoting also the absence of the social questions inherent to the processes of teaching and learning. It is with this perspective, however, that post colonialism is considered a theoretical site for the affirmation and the reinvention of the Pedagogy of the Oppressed, an obligatory reference in the construction of a prudent knowledge for a decent life (SANTOS, 2006)

Nacionalização do trabalho e constituição: análise das regras de nacionalização do trabalho à luz do princípio da isonomia

There is a clear relationship between citizenship and labor market. While foreign nationals are equal in dignity and rights in the laws governing the employment of this labor force. Motivated by reasons of state security or political direction, such laws to a greater or lesser degree, create establish a system of worker protection in the face of the foreign national. These rules have a direct impact on economic regulation, as they can affect the supply of skilled labor or not, articulating with the economic order envisaged by the 1988 Constitution. The Constitution adopts several principles in its economic order, so that the issues involving the rules of the nationalization of all work must be considered in a systematic way, one can not choose a pleasure interpreter. The nationalization of the work rules are not unique to Brazil, similar rules exist in several countries of South America and Africa. In Europe they already existed, but lost out on the basis of treaties setting up the European Union, although other mechanisms are used for the purpose of protecting the citizens of the member states, making policies equal treatment legislation symbolic. The nationalization of the work rules governing the relationship between nationality and the labor market and are in a legal category, which has a function to fulfill in the Brazilian legal system. Not all rules nationalization violate the principle of equality, as it is possible, depending on the circumstance indeed adopt a criterion that implies differentiation between nationals and foreigners. The Constitution has a will arising from its normative force, so that the assumptions it (constitution) used to discriminate may also be possible by ordinary legislation, since the situation is actually justifiably constitutional

Relações internacionais: o comércio exterior do Brasil e Rio Grande do Norte no período de 1999 a 2008

The period post-war promoted several changes in relations economic, political and social world. Since then, a new division international of labor has delineated, with the great growth of Asian countries. In the field of international relations, the world still appears to transition is not completed because the old institutions were not replaced by new ones and the power of the United States as a major capitalist country remains unshaken, even with the emergence and strengthening of new economic global blocs. With globalization, Brazil emerges with more intensity in the face of new issues global, although its share in transactions trade global hasn‟t changed accordingly. In this sense, the objective of this dissertation is to examine, in a descriptive and critical the development of international relations and trade of Brazil and Rio Grande do Norte with the main blocs in the world from 1999 to 2008. As a secondary objective: to identify the assumptions theoretical that underpinned the decisions governments of the FHC and Lula, in particular, the interference of these terms in international relations and foreign trade. Adopted as the procedure methodological the literature review of the subject, as well as collection and processing of the data of foreign trade. During the Cardoso government has undergone the substantial growth in imports, as part of the economic policy of anti-inflationary, generating large deficits trade. From the first to the second term, with the inflection of exchange rate policy the country has resumed surpluses trade. The choice of government of the autonomy participation increased the relative share of the traditional blocks in total foreign trade and reduced the share of MERCOSUL. In the Lula government, there is the maintenance of some elements of the economic policy of the previous government and the partial shift in the conduct of foreign policy, with the option of autonomy through diversification, raising its stake on the blocks and other emerging countries in total foreign trade Brazilian and reducing the contribution of the traditional blocks such as NAFTA and the European Union. A trend observed in the previous government and deepened in the Lula government was the growth in commodity exports and the decline of manufactured products, confirming the model of conservative insertion of Brazilian exports. The Rio Grande do Norte followed the trend Brazilian in the growth of foreign trade, including in participating conservative, given that the products exported by the state are basically coming from horticulture irrigated and agribusiness. However, in the aspect of destination export, the state followed trajectory distinct from that in the Lula government, with the deepening of trade relations with traditional blocks, especially with the European Union and NAFTA

Nietzsche e a modernidade: da crítica à metafísica à crítica à democracia

This dissertation presents an interpretation concerning the critical considerations of the German philosopher Friedrich Nietzsche on Modernity, especially Nietzsche s criticism of Modernity, of Christian mores and democracy produced by him in Beyond Good and Evil. Nietzsche attentively analyses details of Modernity, produces a diagnosis of modern man and discovers the sign of decay. We consider that Nietzsche s criticism of modernity is directly linked to the criticism of classic metaphysics. We emphasize questions like: what in us aspires to truth? Christian mores: why and what for? What characterizes modernity? Could it be the appeal to the democratic taste? Is it possible to reinvent Modernity? We stress the relation between the notion of truth, democracy and Christian mores, showing that these mores were also inherited from the Socratic culture. We also intend to clarify Nietzsche s proposal of a new way of doing philosophy, that would be able to surpass the decay which rules in European modern culture. The end of this research points out to the ―philosophers of the future‖ who are able, according to Nietzsche, to claim life beyond the metaphysics opposition, beyond the good and the evil

Mecanismos de transmissão de preços e parcelas de mercado: uma análise sobre as exportações brasileiras de manga

Climate and environmental conditions allowed Brazil to become one of the largest producers of tropical fruits in the world. The São Francisco Valley, over the years, has emerged as the main fruit-producing region of the country, especially mangos and grapes. The mango, which is produced in this region, has reached a good international position, especially in European and American markets. However, the domestic price has absorbed more and more the impact of fluctuations in the international market expectations affecting the production and marketing of producers. The objective of the study is to analyze the transmission ratio of export prices of the mango, with the American market prices and the European Union in the period from 2003 to 2013. It is intended also to analyze the factors affecting the fluctuations of exports Brazilian mango for the main import markets. To achieve the proposed objectives, we used, in the methodology, the autoregressive vector model, in order to find the price transmission mechanism and the mechanisms of impacts through the impulse response function. We also used, the Constant Market Share model, in order to observe the importance of the effects competitiveness, destination, and growth in world trade on the changes of Brazilian mango exports in the period. The data used were obtained from the database of the Ministry of Development and Foreign Trade - MIDIC and FAOSTAT (Food and Agriculture Organization of the United Nations). Among the results, it was found that the Brazilian domestic prices are influenced by the US market price, and that price shocks promoted this market can impact on the growth of the internal prices for several months. It was noted also that the competitiveness effect accounted for the largest portion of the effective growth of Brazilian exports, in other word, the country has improved its competitiveness among the other exporting countries.

Estudo da adição de resíduos de quartzitos para obtenção de grés porcelanato

In States of Paraíba (PB) and Rio Grande do Norte (RN), northeast of Brazil, the most significant deposits of non-metallic industrial minerals are pegmatites, quartzites and granites, which are located in Seridó region. Extraction of clay, quartz, micas and feldspars occurs mainly in the cities of Várzea (PB), OuroBranco (RN) and Parelhas (RN). Mining companies working in the extraction and processing of quartzite generate large volumes of waste containing about 90% SiO2 in their chemical composition coming from quartz that is one of the basic constituents of ceramic mass for the production of ceramic coating. Therefore, this work evaluates the utilization of these wastes on fabrication of high-quality ceramic products, such as porcelain stoneware, in industrial scale. Characterization of raw materials was based on XRF, XRD, GA, TGA and DSC analysis, on samples composed by 57% of feldspar, 37% of argil and 6% of quartzite residues, with 5 different colors (white, gold, pink, green and black). Samples were synthesized in three temperatures, 1150°C, 1200°C and 1250°C, with one hour isotherm and warming-up tax of 10°C/min. After synthesizing, the specimens were submit to physical characterization tests of water absorption, linear shrinkage, apparently porosity, density, flexural strain at three points. The addition of 6% of quartzite residue to ceramic mass provided a final product with technological properties attending technical norms for the production of porcelain stoneware; best results were observed at a temperature of 1200°C. According to the results there was a high iron oxide on black quartzite, being their use in porcelain stoneware discarded by ethic and structural question, because the material fused at 1250°C. All quartzite formulations had low water absorption when synthesized at 1200°C, getting 0.1% to 0.36% without having gone through the atomization process. Besides, flexural strain tests overcame 27 MPa reaching the acceptance limits of the European Directive EN 100, at 1200°C synthesizing. Thus, the use of quartzite residues in ceramic masses poses as great potential for the production of porcelain stoneware.
