Nas veredas por reconhecimento social: o papel da educação na desconstrução da inferioridade dos sujeitos do campo.

En la travesía por nuevos caminos en la investigación académica, se nos presenta el desafío de investigar alternativas que muestran un horizonte de posibilidades concretas de una educación pautada en la dinámica de organizaciones y movimientos que participan de la lucha por un proyecto de reconocimiento social y desconstrucción de la inferioridad de los sujetos del campo. El escenario de participación de la vida de los que integran la investigación como investigados e investigador es el Territorio Sertão do Apodi, localizado en el estado de Rio Grande do Norte, cuya elección empírica fue motivada por la fuerte presencia y participación de movimientos sociales en el campo. La propuesta es investigar posibilidades y desafíos de prácticas y acciones educativas tanto dentro como fuera de la escuela que buscan reconocer y dar visibilidad a los sujetos sociales del campo en el referido Territorio. Así, será objeto de nuestra investigación el espacio de tomada de decisiones y de organización de institucionalidad territorial a través de la actuación del Colegiado del Territorio del Sertão do Apodi y de las prácticas educativas resultantes de las demandas de las acciones territoriales, tanto escolares como no escolares. La literatura en la cual sedimentamos las bases teóricas fundamentales de esta investigación es la de Axel Honneth (2001; 2003), asociada al pensamiento de Boaventura Santos (2003; 2008a), Jesse Souza (2003, 2006) y Milton Santos (2006, 2007, 2009). Vale destacar, aún, la interlocución con la narrativa de Guimarães Rosa, a través de la obra Grande Sertão: Veredas, sobrepasando todo el conjunto del texto. Con esta intención, procuramos defender que una perspectiva de educación destinada a los sujetos del campo debe pautarse en la superación de la condición de invisibilidad social, a que estos están sometidos, por medio de una postura de reconocimiento social que se afirma en el ejercicio de la democracia participativa y en la reparación de desigualdades sociales. Para esto, son muchos los desafíos y las vulnerabilidades de este proceso; y desde ahí, abriremos caminos para lograr el reconocimiento del papel de la educación y el fortalecimiento de las identidades sociales, al situar al sujeto socialmente, permitiendo que se localice en un determinado grupo social, frente a los saberes construidos en la sociedad

Animais não humanos: a construção da titularidade jurídica como novos sujeitos de direito

This work has the main goal on the recognition of the inherent value of nonhuman animals, under the constitutional framework. It is presented the main philosophical formulations of the current pattern of behavior that rules the relationship between man and animals: first those that have excluded animals from moral consideration and then the thinkers which do have included, in some way, in order to elucidate the origin of the anthropocentric thought over the natural world. In this way, the analysis these thinkers that have included animals in moral consideration will contribute to a paradigm change from the anthropocentric view, initiating legal debates. It will be made a simplified analysis of different philosophical and legal points of view that have been demonstrating the posture in which the human beings have been dealing with the environment, with the replacement of the anthropocentric thinking for the biocentric view, in which life becomes the center of existence. Life is life, no matter whether it is human or not, has a value in itself, and must be protected and respected by the legal system. Then, it will be analized the constitutionalization of the nonhuman animal dignity in comparative law; the infraconstitutional legislation which concerning the intrinsic value of all life forms and, finally, the 1988 Constitution. It will be advocated for non-human animals the condition of subjects, presenting some cases that the Habeas Corpus was used in animal defense. In this new Brazilian Habeas Corpus theory of for apes the argument of genetic proximity was used in order to overcome the literal meaning of natural person to achieve hominids in order to assure the fundamental right of physical freedom. It is realized that the fact that the great apes being recognized as a person does not preclude the possibility of other living beings be recognized as subjects of law. In this way, animals can be considered non-human subjects of law, according to the theory of depersonalized entities and may enjoy a legal category that allows a respect for existential minimum, and can hold constitutional fundamental rights

A função social do contrato como concretização de direitos fundamentais nas relações privadas

This dissertation deals with the social function of the contract, based on constitutional principles, especially those relating to fundamental rights. The social function of the contract (general clause) is described in the Civil Code so intentionally generic, no precise criteria to define it. Because of the fluidity of this principle, it is justified its closer study, seeking to assess its various meanings and looking away from the legal uncertainty that an unlimited conceptual vagueness can cause. The social function of the contract arises from a transformation experienced in private law from the inflows received from the Constitutional Law, the result of an evolutionary process by which it became the state structure, leaving the foundations of the classical liberal state and moving toward a vision guided by existential human values that give the keynote of the Welfare State. Arose, then the concern about the effectiveness of fundamental rights in relations between individuals, which is studied from the inapplicability of fundamental rights in private relations (U.S. doctrine of State action), passing to the analysis of the Theory of indirect horizontal effect of fundamental rights (of German creation and majority acceptance), reaching the right horizontal efficacy Theory of fundamental rights, prevailing Brazilian doctrine and jurisprudence. It has also been investigated the foundations of the social contract, pointing out that, apart from the provisions of the constitutional legislation, that base the principle on screen, there have also been noticed foundations in the Federal Constitution, in devices like the art. 1, III, the dignity of the human person is the north of the relationship between contractors. Also art. 3rd, I CF/88 bases the vision of social covenants, equipping it for the implementation of social solidarity, as one of the fundamental objectives of the Republic. Still on art. 170 of the Constitution it is seen as a locus of reasoning in the social function of the contract, the maintenance of the economic order. It is also studied the internal and external aspects of the social function of the contract, being the first part the one that considers the requirement of respect for contractual loyalty, through the objective good faith, as a result of the dignity of the hirer may not be offended by the other through the contract. On the other hand, the external facet of the social function of the contract, in line with the constitutional mandate of solidarity, indicates the need for contractors to respect the rights of society, namely the diffuse, collective and individual third party. In this external appearance, it is also pointed the notion of external credit protection, addressing the duty of society to respect the contract. There has been shown some notions of the social contract in comparative law. Then, there has been investigated the content of principle study, through their interrelationships with other provisions of private and constitutional law, namely equality, objective good faith, private autonomy and dignity of the human person. We study the application of the social contract in contractual networks as well as the guidance of conservation of contracts, especially those denominated long-term captive contracts, considering the theory of substantive due performance, concluding with an analysis of the social contract in code of Consumer Protection

Efetividade dos direitos trabalhistas e os princípios constitucionais concretizadores da proteção laboral

The Brazilian Constitution aims to regularize the broadest possible the fundamental grounded in the value and supreme principle of human dignity, supporting a Democratic State of Law, to essentially give basic rights to all for a dignified existence. As the result of a historical development, fundamental rights incorporated by legal order represents a real reaction against acts that ignored the dignity of each person in one of these scenarios, especially inserted into the labor relationship, the principle of protection comes to balance and compose such relationship between employers and workers, raising this principle as axiological essence of this subject, based especially on the protection and guarantee of fundamental rights of the worker. For this study, was developed a literature research using books, legislation, legal websites and articles related to the subject, in order to analyze the principle of protection insert in the legal order, properly authoritative on the principle of equality, the social value of the work of human dignity to confer protection to the most vulnerable and admittedly weak of the labor relationship in order to serve the specific regulations legal practical tools and effective protection, against the employer hierarchical power and steering that can not change into abuses and attacks on the fundamental rights of the worker. In conclusion, is not enough, recognizing the vulnerability of the worker, it is necessary to carry out protective legal instruments in line with the the human dignity, consectário logical fundamental rights of workers, to be held in a proportional manner and sometimes flexible, depending on the case. Protection has a beginning and end to ensure that the human dignity that must presuppose a working relationship achieved by orderly and normative power of constitutional norms, with the aim of designing that labor is not an end in itself, but a means to the achievement of the economic advancement by promoting social development and providing necessary support for the increasingly marked impairment of fundamental rights of the worker

Trajetória dos assentamentos rurais financiados pelo crédito fundiário no estado do Rio Grande do Norte: uma análise da experiência do assentamento da fazenda Paz no município de Maxaranguape/RN

The market-assisted land reform (RAAM) has been constituted as an alternative of agrarian reform funded by the Programa Nacional do Crédito Fundiário (PNCF). It is a policy of acquisition, distribution and use of Earth ideologically disseminated and funded by the World Bank in the context of productive insertion of landless workers. Accordingly, this study seeks to analyze the trajectory of rural settlements financed by this policy, seeking to understand what factors promote or limit the process of rural development of those settlements. To do so, take as a reference case study of the Assentamento da Fazenda Paz, in the municipality of Maxaranguape in the State of Rio Grande do Norte. From the methodological point of view, bibliographical and documentary research were used, in addition to visits to the settlement and semi-structured interviews with the settlers, trade union leaders, consultants and technicians linked to the project. Assuming the reports of respondents, initially constructs the hypothesis that informal and formal institutions present in the Assentamento da Fazenda Paz were unable to effectively coordinate the actions of the agents. The results obtained showed the existence of a very complex undertaking, with a total area of 607 hectares and 80 families settled, endowed with good quality water and irrigation infrastructure, with assets of approximately R$ 5 million reais. Experience experienced by the settlers understood the development of complex systems of production and marketing of fruits and vegetables, with an emphasis on the cultivation of papaya in an area of 45 hectares based on modern irrigation system and extensive use of technology. Collective management of production, marketing, revenue and costs stood out as a major challenge for the settlers and their representative organisations, i.e. the Community Association and the cooperative. From this observation it was possible to identify two moments on the trajectory of the project: the first, between 2007-2011, considered by respondents as successful, in which the integration of public policies and abundant input of revenue from the commercialization of the fruits da Paz, mainly through the sale of papaya and pineapple in national and international markets, allowed an average remuneration of R$ 800.00 reais to R$ 1,000 reais seated/monthIn addition to the production of vegetables and other types of products for sale and consumption; the second, from 2012, characterized as a failure, due to the discontinuity of the cultivation, production and marketing of fruits based on the collective bargaining model deployed. Important factors explain the discontinuity of the project, including the model of agriculture implemented, difficulties related to the management of production, marketing and finance the venture, in addition to the breach of trust between the Board of the cooperative and the associates and the distancing of the governmental organizations more directly responsible for the project. It is therefore concluded that we must to rethink rural development as a multidimensional phenomenon, requiring a broad engagement between State and society under the foundations of a territorial development contract

Dificuldades na aprendizagem dos conteúdos de Biologia: evidências a partir das Provas de Múltipla Escolha do Vestibular da UFRN (2001-2008)

Los estudios cerca de las dificultades en el aprendizaje del contenido de la biología han sido foco de la investigación diversa que si ten corido a partir de la década de setenta del siglo pasado, en consecuencia al movimiento de las concepciones alternativas (MCA). El estudio que se presenta, se atan con el Departamento de Educação da UFRN - Base de Pesquisa Formação e Profissionalização Docente, como parte do projeto de pesquisa - A passagem do Ensino Médio a UFRN: estudos sobre o acesso, a permanência e a qualidade do Ensino Médio. Los objetivos de esto investigación, habían consistido en el identificar del contenido explorado en las cuestiones de las Pruebas de la opción múltiple del Vestibular de UFRN para el cual los candidatos habían demostrado dificultad en el aprendizaje; para analizar si el contextualização de la pregunta y la presencia de elementos no-literales que habían influenciado en el aumento de la dificultad de la pregunta e identificar los errores más frecuentemente por los candidatos en estas pruebas. La tesis si configura en dos dimensiones: 1 - El contenido explorado en las Pruebas del Vestibular de la UFRN si distribuya uniformemente a través de los años; sendo priorizados procedimentos que exigem demanda cognitiva diversificadas na solução de problemas; 2- Nessas provas, os resultados dos candidatos, en relación con el Índice de Aproveitamento, indican la existencia de áreas en las quales hay déficit del aprendizaje; qué envolucran las dificultades en aprender el contenido. Los datos de la investigación habían sido recogidos al partir de las pruebas de la biología y de la inicial abstracta selectiva de los informes proveído para el COMPERVE/UFRN, del último los ocho años (2001-2008). En la dirección alcanzar a los objetivos considerados para este estudio, contenta había sido construido a las categorías del análisis - (temas, subtemas y procedimientos); índice de aproveitamento; contextualização de la pregunta; estructura de la pregunta y el error. Los resultados, qué si configurán de los análisis de las ocho pruebas del vestibular de la UFRN y los sesenta y cientos envolvement mil, seiscientos y sesenta y cinco candidatos que le habían contestado; demuestran eso: los temas y los subtemas de la biología para los cuales las dificultades en aprender si está tenido divulgado sea - genética (hibridismo; fenótipo y genotipo; Leyes de Mendel), biotecnología (transgênicos; célula-tronco) y citología (química de la vida; división celular; membranas) y los procedimientos - identificar, analizar la situación y aplicar concepto, para correlacionar y para interpretar el gráfico; los quais não exigem uma alta demanda cognitiva na solução dos problemas. La presencía de situações contextualizadas e de gráficos en las questiones de las pruebas influenciou en el aumento dos niveles dificuldade da of questão para a maioria dos candidatos, reiterando as of dificuldades of observadas na of aprendizagem dos procedimentos. Los errores principales cometidos para los candidatos habían consistido en no reconocimiento del estándar de la herencia del gênica - mendelian y después de-Mendel; no del reconocimiento de los acontecimientos de la división celular y de las técnicas en biotecnología. Éstos habían reflejado las dificultades en aprender del contenido para algún contenido y en otros sugieren que tuviera la expresión de los conceptos alternativos que los estudiantes construyen en los conceptos. Los resultados señalan la necesidad de una revisión de las preguntas inherentes didácticas-metodológicas a la educación del contenido para las cuales las dificultades en aprender si hay tenido presentado

A Internet como tecnointeração da aprendizagem: valorização da cultura e identidade juvenil

The present study investigates Internet as technological interaction in the school environment as a resource of the teaching-learning process. It aims to discuss the lack of synchronicity between proposals of educational access for Internet use and types of access and interaction applied by youngsters. For the development of this research, I resorted to a qualitative, descriptive and explanatory research focused on a group whose subjects are youngsters from eleven to fifteen years of age in a catholic school which belongs to a group of private teaching schools in Natal city, Rio Grande do Norte state. As methodological option it focus on a group and the observation of its participation, discourse analysis and ethnography, considering facts and data of the pedagogical practice concerning the focused theme, besides the attempt to know the youngsters everyday at school and the relationship between them and juvenile cultures. It recognizes the existence of two moments of the focused group: the first related to internet use like technological interaction; the second concerns to the way Internet is problematic as technological interaction in classroom learning. While contacting with youngsters, the study discusses the concepts of Media Environments, Culture, Identity, Network, Consumption and Citizenship. It recognizes that it is relevant for the school to consider Internet a pedagogical tool, directed not just at research, but mostly as learning environment and as learning construction in a collaborative way. It points out the need of approach between school and media environment, reevaluating the pedagogical practice, offering a new evaluation proposal (self-evaluation). It suggests a renewal in the teacher's pedagogical practice in the classroom and using Internet, valuing the connection between technological interaction and communication as motivation elements of student s learning construction and their effective participation in decisions involving citizenship. It gives priority to educational work directed at the establishment of dialogic relationship between codes, learning and contents, leading to the new findings domain in the media environment, enabling the development of abilities and performances directed at the recognition and consumption of information from a critical reading of the media

Pelos caminhos das idéias e da existência: a propósito das cartografias de J. T. de Moura Filho

The present study aimed to investigate the intellectual, personal and professional tracjetory of José Tavares de Moura Filho. Civil engineer who devoted him self to cartographic cience, though not a cartographer, and to literature. At 65 years old, already with retirement, he devoted his attention to writing his books and see the world, as he said. There were nine books, five of poetry, prose and short stories, and four of cartographic nature. The published his books independently. He wrote and his wife Elza typed. Once ready, he would seek the graphics, later a publisher, to reproduce his writing. He liked to say he would rather to pay for your books than bay a new car, and did so. Died at age of 82 years, leaving a rich material for the young students, those who read, as he always did by dedicating his books. In order to achieve the objectives of this study, we used as a theoretical some authors dealing with historiography, oral history, intellectual intineraries and history of ideas, as Garnica, Nóvoa, Barros, Bosi, Le Goff among others. From this perspective, we constructed an archeology of ideas and the existence of Moura Filho, to point contributions of the teaching of mathematics from his work

Gêneros do discurso e escrita: o que as coleções didáticas de português (des)prestigiam no ensino da produção textual?

Through the examination of official indicators, it can be observed that writing is pointed out as one of the main problems concerning formal basic education. However, this teaching-learning object is one of the central objectives at school, having an essential role in different curricular components as well as in the interaction demands required by society. Such paradox indicates, therefore, the relevance of investigations which analyze the intrinsic elements of child development as written text producer. Hence, the main purpose of this research consists of analyzing the treatment given to the types of discourse and the teaching situations in which the written text are produced, concerning Portuguese language didactic material collections approved by Programa Nacional do Livro Didático (PNLD 2010) the Brazilian program of didactic book and worked at elementary school. Such materials correspond to the collections adopted in municipal education system schools from Natal, RN which were below the official education indicator IDEB 2009. Thus, the questions that guide this work are: 1. During writing production lessons, is the diversity of types of discourse effectively worked on didactic collections? 2. Which are the types of discourse and the social spheres prioritized when teaching writing production? 3. How is the situation addressed in the production of the written text should be produced? For this research, we retook the authors Bakhtin, Bunzen, Faraco, Freire, Rodrigues, Rojo, Schneuwly e Dolz and we made a list of all types of discourse and spheres contemplated in the propositions of the writing production in didactical books, concerning the eight collections which compounds the first moment of analysis. Then, we verified how the situation of production is oriented by examining two didactic collections if and how they express the elements referring to the social-historical, functional and linguistic-discursive context of the text to be produced. The data obtained indicate: lack of diversification of types of discourse in the collection that compounds the Aggregate Sample of the research; the conception of a diversity based on the didactic of visiting; the recognition of all canonical and hegemonic types of text as one of the privileged objects of study; the centralization on the standard variety of the language and the devaluation of the representative types of cultural diversity; the shortage of productions which retrace to written language related to different technologies of communication and information; and the little emphasis on the types of discourse related to public language practices. As for the situations of production, it is observed the predominance of the school as a producer of dialogic relationships, whose propositions present, for example, text addressees, enunciative positions, support and contexts of restricted circulation, especially at school. Two divergent situations are observed among the collections: the lack of a work in which the situation of production is under the perspective of the types of discourse as object of teaching-learning; the concept of the types of discourse as object of reflection, presenting a differentiated didactic orientation towards the situation of production. This research contributes, therefore, with a mapping of the existence and the treatment of the types of discourse on propositions of writing production in didactic books; with the critical analysis of the approach of written activities, considering the elements of the historical-social, functional and linguistic-discursive context; thus, through teaching, research and public policies, use and selection of didactic material for the area

Body art, existência e conhecimento :a percepção do corpo na Educação Física

In the Renaissance, the anatomy project a map of the body. Since then, the human body has been investigated for innumerable techniques, configuring new landscapes on the condition human being and the proper knowledge. In accordance with Merleau-Ponty (1975), All technique is body technique. It configures and extends the Metaphysical structure of our meat. In this direction, any intervention in the human body, a tattooing, a surgery or a performance, extends the perception and the directions of the existence of the subject. Merleau-Ponty (1975) still affirms, that all technique presents objective interventions. However, the body, ahead of these interventions, doesn t have to be considered only object, but subject that, from the interventions, attributes sensible and meanings through the movements, also being this its way of being in the world. Searching to extend this reflection on the discontinuities between the object body and the subject body, as well as, with the objective to reflect on the relation between the corporal techniques and the production of the subjectivity and the knowledge of the physical education, we reflect on the body art, as one technique of body that marks the exterior of the body, exteriorizing the subjectivity, to search new means to the body and that ahead of this, we believe being able to project innumerable directions for the corporal transformations in the contemporarily. As a method for our reflection in we will support them in the phenomenology. IT presents as a new ontology, in which distinction does not occur enters the operating paper of the citizen that knows and the influence of the known object. The phenomenological understanding of body will be able to contribute with the knowledge of the Physical Education, a time that gives us important arguments on the experience of the body in relation with the nature, the culture, history. To be a body is to be tied to a world that we do not possess completive, but that we do not cease to search it

Beirando a vida, driblando os problemas: estratégias de bem viver

The purpose of this study is to analyze the strategies used by families living in at-risk-and-vulnerable situations registered with the Estratégia Saúde da Família (ESF) ( Family Health Strategy ) as they face their daily problems. This is an investigation of a qualitative nature, using interview as the main tool for an empirical approach. Ten women from the Panatis location in northern Natal, Rio Grande do Norte, whose families live in precarious social-economical situations were interviewed. The interviews occurred between the months of April and June, 2007. The reports revealed that a mixture of improvisations and creativity was used as strategies for overcoming the privations and necessities of daily life. We also reached the conclusion that these families sought solutions for their problems through religiosity and a gift reciprocity system as resources for obtaining personal recognition and support in adversity. The results, in addition, point to ESF as one of the strategies used by these families in the search for attention and care. From this perspective, ESF has proven to be a place for listening and the construction of ties that are consolidated through home visits, organized groups, in parties and outings that are promoted in the community, reestablishing contact and support among people and signaling a way out of abandonment and isolation. Holders of knowledge constructed through life experiences, the participants of the study led us to induce and infer the need to amplify space that will allow them to express meanings, values and experiences, and consider that becoming ill is a process that incorporates dimensions of life that go beyond the physical. As health professionals, we need to be aware of the multiple and creative abilities used in the daily lives of these families, so that we can, along with them, reinvent a new way of dealing with health

Reconhecimento de voz através de unidades menores do que a palavra, utilizando Wavelet Packet e SVM, em uma nova estrutura hierárquica de decisão

The automatic speech recognition by machine has been the target of researchers in the past five decades. In this period have been numerous advances, such as in the field of recognition of isolated words (commands), which has very high rates of recognition, currently. However, we are still far from developing a system that could have a performance similar to the human being (automatic continuous speech recognition). One of the great challenges of searches for continuous speech recognition is the large amount of pattern. The modern languages such as English, French, Spanish and Portuguese have approximately 500,000 words or patterns to be identified. The purpose of this study is to use smaller units than the word such as phonemes, syllables and difones units as the basis for the speech recognition, aiming to recognize any words without necessarily using them. The main goal is to reduce the restriction imposed by the excessive amount of patterns. In order to validate this proposal, the system was tested in the isolated word recognition in dependent-case. The phonemes characteristics of the Brazil s Portuguese language were used to developed the hierarchy decision system. These decisions are made through the use of neural networks SVM (Support Vector Machines). The main speech features used were obtained from the Wavelet Packet Transform. The descriptors MFCC (Mel-Frequency Cepstral Coefficient) are also used in this work. It was concluded that the method proposed in this work, showed good results in the steps of recognition of vowels, consonants (syllables) and words when compared with other existing methods in literature

Reconhecimento de padrões de falhas em motores trifásicos utilizando redes neurais

This work presents a diagnosis faults system (rotor, stator, and contamination) of three-phase induction motor through equivalent circuit parameters and using techniques patterns recognition. The technology fault diagnostics in engines are evolving and becoming increasingly important in the field of electrical machinery. The neural networks have the ability to classify non-linear relationships between signals through the patterns identification of signals related. It is carried out induction motor´s simulations through the program Matlab R & Simulink R , and produced some faults from modifications in the equivalent circuit parameters. A system is implemented with multiples classifying neural network two neural networks to receive these results and, after well-trained, to accomplish the identification of fault´s pattern

Aplicação de técnicas de aprendizado de máquina no reconhecimento de classes estruturais de proteínas

Nowadays, classifying proteins in structural classes, which concerns the inference of patterns in their 3D conformation, is one of the most important open problems in Molecular Biology. The main reason for this is that the function of a protein is intrinsically related to its spatial conformation. However, such conformations are very difficult to be obtained experimentally in laboratory. Thus, this problem has drawn the attention of many researchers in Bioinformatics. Considering the great difference between the number of protein sequences already known and the number of three-dimensional structures determined experimentally, the demand of automated techniques for structural classification of proteins is very high. In this context, computational tools, especially Machine Learning (ML) techniques, have become essential to deal with this problem. In this work, ML techniques are used in the recognition of protein structural classes: Decision Trees, k-Nearest Neighbor, Naive Bayes, Support Vector Machine and Neural Networks. These methods have been chosen because they represent different paradigms of learning and have been widely used in the Bioinfornmatics literature. Aiming to obtain an improvment in the performance of these techniques (individual classifiers), homogeneous (Bagging and Boosting) and heterogeneous (Voting, Stacking and StackingC) multiclassification systems are used. Moreover, since the protein database used in this work presents the problem of imbalanced classes, artificial techniques for class balance (Undersampling Random, Tomek Links, CNN, NCL and OSS) are used to minimize such a problem. In order to evaluate the ML methods, a cross-validation procedure is applied, where the accuracy of the classifiers is measured using the mean of classification error rate, on independent test sets. These means are compared, two by two, by the hypothesis test aiming to evaluate if there is, statistically, a significant difference between them. With respect to the results obtained with the individual classifiers, Support Vector Machine presented the best accuracy. In terms of the multi-classification systems (homogeneous and heterogeneous), they showed, in general, a superior or similar performance when compared to the one achieved by the individual classifiers used - especially Boosting with Decision Tree and the StackingC with Linear Regression as meta classifier. The Voting method, despite of its simplicity, has shown to be adequate for solving the problem presented in this work. The techniques for class balance, on the other hand, have not produced a significant improvement in the global classification error. Nevertheless, the use of such techniques did improve the classification error for the minority class. In this context, the NCL technique has shown to be more appropriated

As provas metafísicas da existência de deus em René Descartes

Le but de cet article est de présenter les éléments de preuve de l existence de Dieu présentée dans les Méditationes Métaphysiques de René Descartes, en soulignant son importance et son rôle dans le projet philosophique cartésien. La recherche visait á comprendre comment Descartes, étant um homme de science, la recherche de Dieu dans le pilier et d assurer leur philosophie. Par consé quence que Descartes propose de remplacer lui promettant de construire une nouvelle science fondée sur des bases sûres. Ainsi, le texte suit um ordre qu une partie de doute méthodologique comme um élément essentiel pour surmonter une connaissance née de l incertitude et généralisée et d opinions comme étant de droite, pour finalement atteindre la vérité dans les sciencies, Grace à la découverte Du premier cours, le cogito, moi pensant, alors existantes. Trouvé cette certitude, le sujet qui a en elle l idée d um être infini qui contient toutes perfections et, comme Il fera la démonstration de la preuve a posteriori et a priori. Et donc cet être ne peut pas être considéré comme inexistant projet assurant Descartes
