SINAES: as diferentes faces da avaliação na UFRN

This thesis entitled SINAES: the different faces of the evaluation at UFRN, aims to analyze the configuration that the national policy for assessment in higher education has taken on UFRN. We assume that in recent years there are an oscillation between the concepts of evaluation, according with the logic of public administration it has preferred an approach that presents itself as a promoter of quality, sometimes with regulatory aspects, sometimes with educational ones. The text discusses the use of the new assessment tools for higher education placing them under the new demands on state reform context in which this is to promote and measure quality based on the values of excellence and competitiveness. This movement arises from the redefinition of the role of the State that has been taking features of Evaluator State. From a historical review of government initiatives in the field of evaluation, we analyze the characteristics of assessment policies outlined over the past decades. We are based on the theoretical method that aims to examine the multiple determinants that shape a particular reality from the larger movement of totality. To identify, in this case, connections and ruptures that have emerged over the history of assessment policies aimed at higher education by checking their determinants in order to better explain the reality. To investigate the object of this study we used as instruments: the research literature and research documents, the semi-structured interviews and non-participant observation. The study revealed that there are different practices of evaluation and that before to establishment the SINAES program, the UFRN already had a culture of an institutional assessment, more participatory and democratic, opposing to the rigidity of the self-assessment in SINAES program that it was instituted by the Commission for assessment (CPA). We also noticed that the implementation of the SINAES at URFN has been performed very slowly and the breadth and complexity of the evaluation process has contributed to hinder its implementation in all dimensions provided by MEC. Although it was observed that in its operationalization the SINAES has assumed a more normative assessment and directed to establish rankings between courses and higher education schools than to establish a more qualitative assessment in this system. As regards the evaluation of the undergraduate course studied on this research and subjected to the three dimensions of evaluation proposed by SINAES (self-assessment, Evaluation of Courses and ENADE) it was not possible to verify an effective integration between the methods of assessing conducted. The results are considered separately, in only a partial view of the course evaluated the proposal what pits the SINAES as a system that involves the totality

Depósitos de calda de pulverização nas faces adaxial e abaxial de folhas de Eichhornia crassipes dispostas em diferentes ângulos

Estudos foram conduzidos com o objetivo de avaliar os depósitos de gotas pulverizadas através de dois tipos de pontas sobre as faces adaxial e abaxial de folhas de Eichhornia crassipes dispostas em diferentes ângulos. No primeiro estudo, os tratamentos foram dispostos no esquema fatorial 2x4x7: dois tipos de pontas (TX12 e XR11002VS), quatro ângulos verticais (0º, 30º, 60º e 90º) e sete ângulos horizontais (0º, 15º, 30º, 45º, 60º, 75º e 90º). No ângulo vertical de 90º a lâmina foliar foi posicionada paralelamente ao sentido de deslocamento do jato de pulverização; e no ângulo horizontal de 90º a folha foi posicionada perpendicularmente ao plano do solo. Como traçadores, foram utilizadas soluções de 1.000 ppm do corante Azul FDC-1 e 3.500 ppm do corante Amarelo Tartrasina para as pontas tipo leque e cone, respectivamente. No segundo estudo, os tratamentos foram dispostos no esquema fatorial 2x2x3: dois tipos de pontas (TX12 e XR11002VS), dois tipos de calda (com e sem Aterbane BR a 0,5%) e três ângulos horizontais (0º, 45º e 90º). Adotou-se o ângulo vertical de 90º como padrão para todos os tratamentos. Soluções de 1.000 ppm do corante Azul FDC-1 e 3.500 ppm do corante Amarelo Tartrasina foram utilizadas como traçadores para a calda com e sem surfatante, respectivamente. Os resultados do primeiro estudo revelaram que os depósitos observados em toda a folha e na face adaxial das lâminas foliares de aguapé diminuíram à medida que se aumentou a angulação vertical, independentemente da ponta utilizada. Os menores depósitos sempre estiveram relacionados ao ângulo vertical de 90º, independentemente do ângulo horizontal utilizado. Não foi detectado nenhum depósito na face abaxial das folhas de aguapé em todas as combinações dos fatores estudados. No segundo estudo também foram observados os mesmos decréscimos no volume de calda depositado em toda a folha e na face adaxial à medida que se aumentou a angulação vertical das lâminas foliares. As duas pontas proporcionaram depósitos nulos na face abaxial quando o surfatante não foi utilizado; entretanto, a adição do surfatante à calda incrementou significativamente os depósitos nesta face da folha do aguapé.

Ulisses e Narciso: as faces da alma humana através do discurso mítico nas Enéadas de Plotino

This dissertation, witch studies the myth in Plotinus, attempts to set an approach to the comprehension of the mythic discourse as image related to the ethical process in the Enneads. In order to achieve it, the analysis of the mythic narrative will be employed in the philosophical context that has as a starting point a revisit of the platonic poetic conception. As central questions the notable mythological figures of Narcissus and Ulysses will be utilized to put into context the notion of the Plotinian soul and its endeavor of returning to the originary unity. Therefore, by following the course of both figures in their respective narratives, it conceives a possible relation of ascension and fall of the soul. The first part of this study intends to show Plato s interpretation on the myth and Plotinus standpoint in regard to it. Moreover, it observes Plato s criticism on poetry in the context of the Greek Paideia and the notion of the myth as image of the henological structure in Plotinus, who perceives in the myth its exemplifying nature. The second part attempts to structure Plotinus philosophy, contrasting Henology and Ontology, therefore exposing the three hypostases and the comprehension of the intelligible. The third part endeavors to display the sense of the myth, the idea of the myth as image in Plotinus and the roles of the mythical figures in the Enneads

Factors affecting nucleolytic efficiency of some ternary metal complexes with DNA binding and recognition domains. Crystal and molecular structure of Zn(phen)(edda)

The binding selectivity of the M(phen)(edda) (M = Cu, Co, Ni, Zn; phen = 1,10-phenanthroline, edda = ethylenediaminediacetic acid) complexes towards ds(CG)(6), ds(AT)(6) and ds(CGCGAATTCGCG) B-form oligonucleotide duplexes were studied by CD spectroscopy and molecular modeling. The binding mode is intercalation and there is selectivity towards AT-sequence and stacking preference for A/A parallel or diagonal adjacent base steps in their intercalation. The nucleolytic properties of these complexes were investigated and the factors affecting the extent of cleavage were determined to be: concentration of complex, the nature of metal(11) ion, type of buffer, pH of buffer, incubation time, incubation temperature, and the presence of hydrogen peroxide or ascorbic acid as exogenous reagents. The fluorescence property of these complexes and its origin were also investigated. The crystal structure of the Zn(phen)(edda) complex is reported in which the zinc atom displays a distorted trans-N4O2 octahedral geometry; the crystal packing features double layers of complex molecules held together by extensive hydrogen bonding that inter-digitate with adjacent double layers via pi...pi interactions between 1,10-phenanthroline residues. The structure is compared with that of the recently described copper(II) analogue and, with the latter, included in molecular modeling. (C) 2008 Elsevier B.V. All rights reserved.

As Faces e os Disfaces da Informalidade no Capitalismo Conteporâneo: Um Estudo do Comércio de Rua em Pau dos Ferros/RN

This paper discusses the expression of informality in contemporary capitalism. Thematic of relevance to the analysis of the reality of work today and the logic that moves the capital, its real presence in the lives of individuals. The street trading of Pau dos Ferros town, popularly known as "street market" was chosen as the search space. The main objective is to seize and examine the articulations and logic, present in the configuration of the street trading of this city, located in the state of Rio Grande do Norte, explaining the functionality of informality for capitalist accumulation, but also for the reproduction of segments of the working class. Our analysis is based in the perspective of totality, trying to grasp the historical determinations of the phenomenon in focus. It includes the analysis of the mechanisms used by the capital to reproduce itself in the current historical context, which has been implicated in the composition of the labor markets of different countries and in various forms of exploitation to which workers in general are subject. It also means discussing the development of capitalism in Brazil, the logic that permeates its dependence, and especially the use of over-exploitation of labor, as a lever for internal accumulation. The course of investigation consisted of theoretical research to form the basis of theoretical and methodological analysis and to outline the context in which our research object is inserted, and field research conducted in two phases: systematic observation, which allowed to map traders features and the infrastructure of commerce, and the conduction of interviews with key informants. The material collected was scrutinized according to analytical scheme inspired by the content analysis. Among the main considerations developed from the research process we include: the street trading of Pau dos Ferros remains shrouded in the majority sale of agricultural products, this demonstrates the structural characteristics of the region. However, the supply of this product is no longer restricted to the excess of small local producers. The presence of the dealer changed the distribution of the product, streamlining it. In parallel, business practices are developed, practices in which traded goods (industrial) reflect the moment of capitalist restoration, a larger business network. The reflections also made it possible to show that street trading follows developing on the basis of informal work, which gains functionality to the system, as it is configured as a space commonly used to drain part of the production, of industries (clothing/shoes), especially if the distribution is considered as an essential element of the complex process that aims at capital appreciation. This activity has been functioning as a place of employment and income generation for the subjects who are away from formal employment, masking, this way, unemployment, moreover, they allow them to continue as consumers. Such expressions reflect the ability and the logic of capital to expand and aggregate into so many realities. It is underway today, the logic that has led many workers to join the project of domination of capital, by the illusory chance to become capitalists. The aim has been to turn the subject into a consumer and the worker an enterprising

A assistência estudantil e as cotas sociais nas universidades estaduais do nordeste: as faces do acesso ao direito

This paper discusses about the higher education in Brazilian society highlighting the struggle of the working class, as concerning the access to public universities, as well as highlights the contradictions implicit in social quotas adopted by Higher Education Institutions (HEIs) . The aim of this paper is on presenting the analysis of student assistance of the state universities in the Northeast that adopt quotas as social criteria of access for its students , presenting investigative locus as the following universities : UERN , UEPB , UPE and UNEAL . The paper presents the results of a qualitative study , based on a documentary analysis , based on dialectical and historical materialism in which she performed the reading of data from the following analytical categories: Higher Education, Social Quotas and Student Assistance. As main results, it is emphasized that the implementation of quotas as a means of access to higher education was not decisive for the form of planning and implementation of student assistance the university investigated; latent heterogeneity is that universities deal with actions to support student residence. And it is this heterogeneity and the variation in the conduct and understanding of student assistance , reflecting the lack of prioritization with the actions of the context of HEIs ; support programs are to stay focused on central campuses which are located the administrative offices of the universities, penalizing students enrolled in advanced units; also highlight that there is no link between the programs and projects related to student assistance with actions related to teaching, research and extension in universities investigated , which ultimately characterize the student assistance as an isolated action and punctual

Avalição de reusabilidade de aplicações web baseadas em frameworks orientados a ações e a componentes: estudo de Caso sobre os Frameworks Apache Struts e JavaServer Faces

Over the years the use of application frameworks designed for the View and Controller layers of MVC architectural pattern adapted to web applications has become very popular. These frameworks are classified into Actions Oriented and Components Oriented , according to the solution strategy adopted by the tools. The choice of such strategy leads the system architecture design to acquire non-functional characteristics caused by the way the framework influences the developer to implement the system. The components reusability is one of those characteristics and plays a very important role for development activities such as system evolution and maintenance. The work of this dissertation consists to analyze of how the reusability could be influenced by the Web frameworks usage. To accomplish this, small academic management applications were developed using the latest versions of Apache Struts and JavaServer Faces frameworks, the main representatives of Java plataform Web frameworks of. For this assessment was used a software quality model that associates internal attributes, which can be measured objectively, to the characteristics in question. These attributes and metrics defined for the model were based on some work related discussed in the document

As múltiplas faces da evasão na educação superior a distância: a experiência do curso de tecnologia em gestão ambiental do IFRN em dois pólos de apoio presencial

This research presents a reflection on the dropout rates in higher education courses available through distance education in a context marked by deep changes in various spheres of society and by the uncontrolled growth of this educational method. For this, the object of analysis is related to the reality of students of Technology in Environmental Management offered by the Instituto Federal de Educação, Ciência e Tecnologia, Rio Grande do Norte (RN), Brazil, through the distance education in presence support poles located in Mossoró (RN) and Martins (RN). In this field research development several strategies of data collection are used, such as participant observation of reality; analysis of documents related to distance education and to the classes in Technology in Environmental Management; questionnaires answered by students who dropped the course. The results of such research enable us to say that the dropout rates in distance higher education is mainly referred to the consequences of a combination of aspects involved in the course development, personal difficulties faced by students during the period they attend the lessons and elements inherent in the context in which the course and students are inserted. Nevertheless there are specific situations in which the student may drop the program due to the influence of a single aspect, whether it is inherent in the development of the course, a personal situation, or even a factor determined by the context in which the course or the student belongs to

Política da literatura e suas faces na palavra muda de Manoel de Barros

Ce travail de thèse ici proposé a comme but de recherche la production litéraire du poète brésilien Manoel Wenceslau Leite Barros, Manoel de Barros, (1916 Cuiabá-MT) en l articulant avec la reflexion sur le concept de politique de l écrite proposé par le philosophe algérien-français Jacques Rancière (1940 Algiers Algérie). L hypothèse qui se presente est celle sur l écrite poétique de Manoel de Barros dont les ―marques du sensible‖ dans les expériences démocratiques sont perceptibles. Sa production inclue ce que se peut denominer d une micrologie poétique, une reconfiguration du ―partager‖, dans le sense de l élaboration pratiques de l égalité, des pratiques de redistribution et de circulation des voix, instauratrices de la constitution esthétiques des communautés différenciées, considérées comme alternatives, face au modèle de système canonique de la litérature. Au moment que sa fonctionnent comme des formes de subvertions, elles produisent des espaces ou marge d émancipation de l être : lecteur et écrivain, en déclanchant des nouvelles perspectives éthiques et esthétiques. De cette manière, l objectif qui se dessine est ce qui comprend comment se configure la proposition d une politique de l écrite de Manoel de Barros et la façon qu elle se place par rapport à une politique des arts. Pour cela, nous utiliseront comme base la pensée de Jacques Rancière qui se fait remarquer, les dernières années, pour entreprendre une refléxion systématique et lucide par rapport aux relations éxistantes entre esthétique et politique dans la société présente, alié à ce que se défine comme des manières et des formes de penser élaborées par le texte poétique (lui même) de Manoel de Barros et de manière incontinué dans ses entretiens-critiques, plubliées dans des journaux et revues, présentées en vidéos, et nous n oublierons pas non plus des contributions théoriques et des refléxions parvenues de la pensée contemporaine
