Avaliação dos indicadores de desempenho de instituições federais de educação tecnológica doBrasil na abordagem do balanced scorecard

This Master of Science Thesis deals with a study on applying the BSC Balanced Scorecard to assess the performance of Federal Institution for Technological Education Institution in Brazil, a government organizations non for profit. It s accomplished a literature review in order to understand the BSC and its application to non for profit organizations and as a main result it is proposed a BSC conceptual model with an inversion of the main BSC perspective from financial to customer/society. It is used the annual management report of thirteen Institutions and applied a Pearson correlation analysis in order to verify a cause-effect situation between indicators. The main findings suggest that the model teachers qualification in terms of degree earned, quantity of teachers in full time job, and rate of students by teacher in full time job having good pearson correlation with the results expected of quality, throughput, social and demand response. However, the student unit cost use as the sole financial indicator did not get any reasonable correlation with the results, as so the quality and quantity of books in the libraries. Although it suggests a need for improvement in the model, the general model adopted appears to be satisfactory as a starting point to a BSC-like performance measuring system to this kind of Institutions

Uma fundamentação para sinais e sistemas intervalares

In this work we use Interval Mathematics to establish interval counterparts for the main tools used in digital signal processing. More specifically, the approach developed here is oriented to signals, systems, sampling, quantization, coding and Fourier transforms. A detailed study for some interval arithmetics which handle with complex numbers is provided; they are: complex interval arithmetic (or rectangular), circular complex arithmetic, and interval arithmetic for polar sectors. This lead us to investigate some properties that are relevant for the development of a theory of interval digital signal processing. It is shown that the sets IR and R(C) endowed with any correct arithmetic is not an algebraic field, meaning that those sets do not behave like real and complex numbers. An alternative to the notion of interval complex width is also provided and the Kulisch- Miranker order is used in order to write complex numbers in the interval form enabling operations on endpoints. The use of interval signals and systems is possible thanks to the representation of complex values into floating point systems. That is, if a number x 2 R is not representable in a floating point system F then it is mapped to an interval [x;x], such that x is the largest number in F which is smaller than x and x is the smallest one in F which is greater than x. This interval representation is the starting point for definitions like interval signals and systems which take real or complex values. It provides the extension for notions like: causality, stability, time invariance, homogeneity, additivity and linearity to interval systems. The process of quantization is extended to its interval counterpart. Thereafter the interval versions for: quantization levels, quantization error and encoded signal are provided. It is shown that the interval levels of quantization represent complex quantization levels and the classical quantization error ranges over the interval quantization error. An estimation for the interval quantization error and an interval version for Z-transform (and hence Fourier transform) is provided. Finally, the results of an Matlab implementation is given

O uso pedagógico de uma seqüência didática para a aquisição de algumas idéias relacionadas ao conceito de números complexos

The aim of the present work is to contribute to the teaching-learning process in Mathematics through an alternative which tries to motivate the student so that he/she will learn the basic concepts of Complex Numbers and realize that they are not pointless. Therefore, this work s general objective is to construct a didactic sequence which contains structured activities that intends to build up, in each student s thought, the concept of Complex Numbers. The didactic sequence is initially based on a review of the main historical aspects which begot the construction of those numbers. Based on these aspects, and the theories of Richard Skemp, was elaborated a sequence of structured activities linked with Maths history, having the solution of quadratic equations as a main starting point. This should make learning more accessible, because this concept permeates the students previous work and, thus, they should be more familiar with it. The methodological intervention began with the application of that sequence of activities with grade students in public schools who did not yet know the concept of Complex Numbers. It was performed in three phases: a draft study, a draft study II and the final study. Each phase was applied in a different institution, where the classes were randomly divided into groups and each group would discuss and write down the concepts they had developed about Complex Numbers. We also use of another instrument of analysis which consisted of a recorded interview of a semi-structured type, trying to find out the ways the students thought in order to construct their own concepts, i.e. the solutions of the previous activity. Their ideas about Complex Numbers were categorized according to their similarities and then analyzed. The results of the analysis show that the concepts constructed by the students were pertinent and that they complemented each other this supports the conclusion that the use of structured activities is an efficient alternative for the teaching of mathematics

Slogans políticos em campanhas eleitorais no Rio Grande do Norte: a mídia na disputa ideológica.

To the observe the periods of electoral campaigns, we can realize sharply the abundance of political propaganda that announces the candidates, their campaign record, their proposed and everything that can carry them to the victory in the urns. The propaganda is today an essential tool in the votes dispute, in consequence of this, there is, in Brazil, the increasing participation of the Politics Parties in seminars of electoral marketing. They are varied strategies of the media used in the divulging of the candidacies, among them the slogan. Instigated by the explicit relation media/political, this work intends to investigate the ideologies (values) announced by the slogans of political propaganda that circulated in electoral periods. Thus, we base on the theory of the Circle of Bakhtin, who considers the statement as unit of the verbal communication, and that conceives the language as phenomenon dialogical, and, too, in the conceptions of alien words, social voices and dialogical relations formulated by the referred theory. We use, for better to comprehend, the slogan as strategy mediatic, of the classical study done by Olivier Reboul concerning the slogan; and, like starting point of a conception about ideology, studied John Thompson to comprehends the ideological phenomenon. Our corpus it constitutes of 14 political slogans announced in the campaigns for mayor of the cities in Natal and Mossoró, both located in Rio Grande do Norte s state, Brazil, in 1996, 2000 and 2004. For the analysis of these slogans, we consider the social-historical context in which were announced, being contemplated the linguistic and discursive aspect, according to the following methodological order: the identification of alien words (interdiscours); the social voices and the kinds dialogical relations established; and, finally, the ideology announced by the statement. This way, we can arrive to the conclusion that in the electoral context occurs a true ideologies war , in other words, in the political game of an electoral campaign, the slogans announces different values, which vary in several factors function, for example, the historicity, the subject that enunciates, the discursive positionings.

As Filhas do Arco-Íris, de Eulício Farias de Lacerda : mitos, lendas e contos populares como elementos estruturantes do romance

The corpus of this work constitutes an analysis the literary work As Filhas do Arco-Íris, by Eulício Farias de Lacerda, considering object of study myths, legends and popular stories as estruturant elements of the romance. The unchainment of this reading considers aspects of the oral tradition as starting point for the rupture tradition. In that perspective, it became fundamental to describe aspects of the popular culture that consolidated the Brazilian Literature during the 20th century. Like this, it was necessary to understand the development of oral elements and the structuring of the folk-tales, pointing out that As Filhas do Arco-Íris was built in a especial way with regionalist characteristics, following the parameters of the romances published among the years 1930 and 1950. In the researched work, it was noticed a narrative that gathers stories, legends, myths, proverbs and oral locutions. In this, it reveals that the Brazilian literary production grew in aesthetics and thematic. Like this, As Filhas do Arco-Íris is an exercise of the experience regionalist inserted in the contemporary novel, because even with your first publication in 1980, the narrative is configured to the molds of a Romance de 30

O FRAGMENTO EM TUTAMÉIA E NO LIVRO SOBRE NADA

This study is connected to the research line Poéticas da Modernidade e Pós -Modernidade, of the Programa de Pós-Graduação em Estudos da Linguagem, in the subarea: Comparative Literature - CCHLA/UFRN. Its main goal is to see fragmentation of writing as an aesthetic resource highlighted in the work of Tutaméia by Guimarães Rosa (1908-1967), and in Livro sobre nada by Manoel de Barros (1916). We undertake as a starting point the view that these works are allegorical expressions. We have as a basis the German philosopher Walter Benjamin (1984) conception about baroque allegory, that uses amorphous fragment and constitutes a dialectical expression, in which each person, each thing, each relation, may mean any other one (1984, p. 196). We see the stylistic features as used by Guimarães Rosa and by Manoel de Barros in the construction of poetics capable of breaking the boundaries between artistic genres, literary and discursive, adding oral, musical and plastic elements to writing. We also analyze the development of fragmentary poetics, in which the voice of the narrator/lyrical I, the characters, space, plot and time exhibit the fragment as a factor that contributes to the great ambiguity of the two works and to create a new language, performative and vibrant, rich in alluring images, allegories

O ritual simbólico do Ctrl+C (copiar ) e Ctrl+V (colar) no ensino médio

Nowadays, technology has a direct influence on the relationship student and teacher have with language. The internet is a powerful tool in helping work with the language and, through it, the knowledge comes to the student easily and intensely. Furthermore, this facility has enhanced and made visible what has been called, within the University community, "plagiarism generation." This work assumes that this generation has, in their written texts, symbolic movements similar to those of "copy and paste" applied to research work carried out by high school students. Taking this as starting point, this dissertation aims to analyze how high school students of the 1st year from a school in Natal (RN) construct texts, under the movements known as "Ctrl + c" and "Ctrl + v", with reference to the text of the "other". More specific issues are behind the general objective, namely: 1. how the student appropriates the source-text when he copies and pastes? 2. What are the categories of analysis that allow us to look analytically and theoretically for the "ctrl + c / ctrl + v" practice made by the student? 2. how the studies developed in the fields of "Genetic Criticism" (Grésillon, 1987), the "school manuscripts" (Calil, 2004) and "paraphrase" (Fuchs, 1982) may help in working with writing in the classroom standing as a possible way to minimize the copy and paste effects in the students texts? Thus, we observe the categories of analysis that allow us to look, theoretically and analytically, for the symbolic ritual of the "ctrl + c" (copy) and "ctrl + v" (paste) in high school. Our study shows that the student text is a "hybrid body" whose writing is a drawing entanglement because of the presence of the foreign text, verbatim, and the presence of linguistic elements to paraphrase the original text.This textual embodiment has, behind it, certain operations, namely: replacing, moving, adding and deleting statements. Given the specificity of the data and the research objectives, this study aligns with qualitative research methods (SILVERMAN, 2009) and falls within the knowledge field of Applied Linguistics, which is characterized especially by investigating problems, phenomena in which language in a real situation is taken as central (BRUMFIT, 1995).Theoretically, our work follows the approach of studies on the paraphrase (Fuchs, 1982, 1994a, 1994b; DAUNAY, 1997, 1999, 2002a, 2002b), the studies developed in the field of Genetic Criticism (Grésillon, 1987, 1994, 1992, 2008 ) and those developed by Eduardo Calil (2004) on "school manuscripts"

A dupla poética do silêncio: uma análise de Fogo morto e Cartilha do silêncio.

This research presents a reading of the poetics of silence in the profile and actions of characters in Fogo morto, by Paraiba s novelist José Lins do Rego and Cartilha do silêncio, by Sergipe s writer José Francisco Costa Dantas. As a starting point, we intend to demonstrate, through analysis, how the traditional issue of patriarchy, installed in rural areas of Northeast Brazil, live their momentum of rise and decline in different social spaces within narratives. This article shows how man lives tensions caused by the socio-political changes that will gradually be deployed in their environment due to the process of transition from traditional to modern life. From this perspective, this reading encourages a critical reflection on the social space of the mills and farms at the time of their rise and decay, as well as the various gender relationships between the feminine and the masculine world. The analysis indicates that all the changes both in family and social space unfold a world of silent variants and this paper takes as its theoretical basis the concept of silence built from the reflections of Eni Puccinelli Orlandi (2002), Barros Lourival Holland (1990 ), Luiz Costa Lima (1974) and Marisa Simons (1999).

Oxidation of acetylacetone catalyzed by horseradish peroxidase in the absence of hydrogen peroxide

Horseradish peroxidase (HRP) is a plant enzyme widely used in biotechnology, including antibody-directed enzyme prodrug therapy (ADEPT). Here, we showed that HRP is able to catalyze the autoxidation of acetylacetone in the absence of hydrogen peroxide. This autoxidation led to generation of methylglyoxal and reactive oxygen species. The production of superoxide anion was evidenced by the effect of superoxide dismutase and by the generation of oxyperoxidase during the enzyme turnover. The HRP has a high specificity for acetylacetone, since the similar beta-dicarbonyls dimedon and acetoacetate were not oxidized. As this enzyme prodrug combination was highly cytotoxic for neutrophils and only requires the presence of a non-human peroxidase and acetylacetone, it might immediately be applied to research on the ADEPT techniques. The acetylacetone could be a starting point for the design of new drugs applied in HRP-related ADEPT techniques. (c) 2006 Elsevier B.V. All rights reserved.

Improvement of antischistosomal activity of praziquantel by incorporation into phosphatidylcholine-containing liposomes

Praziquantel (PZQ) is effective against all known species of Schistosomes that infect humans. The failure of mass treatment of schistosomiasis has been attributed to the fact that therapy is not sufficiently long-lasting. This effect may be due to the low bioavailability of PZQ that has a low hydrosolubility and fast metabolism. Liposomes have been used to prolong drug levels. reduce the side effects, direct drugs to specific sites and increase bioavailability after administration. The aim of this work was to study the effect of phosphatidylcholine (PC)-containing liposomes to vehiculate PZQ to improve the treatment of schistosomiasis. The in vitro Study was carried out using Schistosoma mansoni parasites recovered by perfusion from the hepatic portal system of infected mice. Suspensions of liposomes with PZQ and free PZQ were administered p.o. in mice after 14 days of infection. The effect of both preparations in vitro on S. mansoni culture was similar. In the in vivo test, PZQ-liposomes caused a decrease in amounts of eggs and parasites. Liposomes improve the antischistosomal activity of praziquantel. This can be used as a starting point to investigate alternative administration routes or dosage forms and to examine the mechanism of intestinal absorption of PRZ © 2005 Elsevier B.V.

Antecedentes histórico-filosóficos da problemática do tempo e do mal no freiheitsschrift de schelling: aproximações gnósticas

This thesis aims better understanding the relation between time and evil in Schelling s Freiheitsschrift, having its starting point in approximations from Gnosticism. For that purpose, before approaching that relation, it is reviewed (chapter I) the question of Gnosticism, a strain of thought essentially concerned with the problem of time and permeated by the belief in an evil nature of creation, and which is alleged to have significantly influenced certain ideas of Schelling. An evaluation of approximations between Gnosticism, gnosis and German thought follows (chapter II), as well as an evaluation of Schellingian aproximations to Gnosticism (chapter III). Then, the Freiheitsschrift is analysed as the text where Schelling, having taken hold of a very distinct appropriation of Gnosticism, goes beyond Kantian theodicy (chapter IV). Some interrogations about whether key ideas of Schellingian philosophy (about gnosis, creation, duality, time, and evil) are conceived in a way that is essentially different from that of historic Gnosticism, despite the much that has been said to the contrary, are then addressed (chapter V). The proposal of a Platonic-Plotinian key to the understanding of the relations between time and evil in the Freiheitsschrift comes next (chapter VI), and then gives way to the concluding remarks (chapter VII). We perceive that Gnosticism and Neoplatonism are systems of thought that sometimes converge, and that German thought is one of the places of this convergence. Notwithstanding this perception, it is possible to affirm that Schellingian thought, with its valorization of time and of a certain perception of evil, is essentially anti-gnostic, despite some contrary observations

A Metafísica da luz em Marcílio Ficino.

The aim of the present dissertation constitutes to analyse the way in how light assumes the meaning of universal bond in the cosmovision of Marsilio Ficino, especially from his works Quid sit lumen, De Sole, De Amore and De Vita. The influence of Marsilio Ficino (1433-1499) in the history of occidental thought is impressive. Besides having translated to Latin the important texts of the neoplatonic tradition, Ficino presided over the Academy of Careggi, congregating important humanists in the top of the Renaissance. His treatises on love, beauty, light, magic and immortality of the soul have influenced strongly the production of other thinkers. The subject of light is of fundamental importance among his works since it is deeply related with all the other aspects of his philosophy. For him, light is spiritual emanation that perpasses everything without staining itself. Originated how the divine goodness, the light blows up in beauty in multiplicity, setting fire on the soul that truily contemplates it and that identifies whith it. The starting point of this loving relation between man and deity is, therefore, the physical world, that occults in itself the metaphysical light.

Filosofar em tempos de informação

This thesis reflects upon the question of how does philosophy think a particular today, which is not only a legitimate philosophical task but a determinative characteristic of philosophy in general. Today's thought follows two paths: first, an hermeneutical-phenomenological analysis of Martin Heidegger's thought with regards to his own contemporaneity; and secondly, through the analysis of the contemporary phenomenon of Information Technology which in the present work is to be considered a privileged sign of our times and distinctive of the mindfulness of philosophy. Therefore, the starting point is an investigation of Heidegger's thinking on his own era to whom facticity is a way of accessing the fundamental question of philosophy. This thesis is led by three guiding words which hold onto a perspective of unity in Heidegger s lifetime of work: 1. Technicity, 2. History, 3. Language, to thereby develop a characterization of human existence as 1. Technopolitical, 2. Technoscientific, and 3. Technological. Finally, in keeping with this triangular characterization of the human, a philosophical comprehension of our times will be established and drawn by Information Technology illustrating three of its' factual signs that are understood to be the 'Remains of Being' today: The Emptying of Speech (Language); The Emptying of Science (History); The Emptying of The Object (Technicity). Through these nowadays phenomenon, it is possible to maintain a grip on the fundamental question, precisely when the task of philosophy seems to have peremptorily lost its meaning and come to its logical end and to show how philosophizing in the information era is as possible as it is necessary.

Nexus: da relacionalidade do princípio à metafísica do inominável em Nicolau de Cusa

We indicate the idea of nexus or conexio, thought of as intelligible connection with the intelligent, the foundation on which the reason why you can understand and name, even if inadequately, what the intellect sees incomprehensible and unnameably. Thus, it opens a way for our research: we will take the idea of nexus as fundamental to the interpretation of the divine names and the "metaphysics of the unnameably" and we show how the divine names, mainly in possest, mirrored in the Trinity, relatedness of the principle and therefore also the nexus. For that you need to think some preliminary questions: we will place Nicholas of Cusa in the tradition of medieval Christian Neoplatonism, we resume some discussions on the problem of naming and the philosophy of language in his thinking, we will reflect such thinking is molded from active dialogue with the tradition and how it is your speculation is founded upon the dynamic and dialectical relationship between philosophy and theology to be thought of in our text using the relationship between faith and understandig (intellectus). After introductory clarify these issues we will come to consider introductory understanding of the Trinitarian Beginning and speculation about the nexus taking as its starting point from where the De venatione sapientiae nexus or conexio is designed as a hunting field of wisdom and the First Book of De docta ignorantia where the maximum is now thought of as one and triune. From the Second Book of the same work and the Idiota. De mente we will show in what sense the universe and men, as imago dei, imitate the eternal Trinity. Finally, we will resume the notion of the scientia aenigmatica of De beryllo and some information that will clarify that Nicholas assumes the divine names as enigmas. Finally, we will try to show that the enigmatic or symbolic names also mirror the triune Beginning principle. So, before we return some traces of this aspect in some divine names and texts of the "late period" and then conclude with that which in itself already indicates the nexus and therefore the trinity: possest
