This research aims at identifying the learning problems in newly undergraduate students at university, interpreting the nature and causes of these problems, offering subsidies to overcome these difficulties and enabling a meaningful learning through which students give meaning to their learning. As an object for this work was chosen the theme Chemical Bonds - where were studied the forces between atoms to form molecules, compound ions and ionic crystalline structures - and is characterized as one of the most important subjects of Chemistry. In research, it was used a questionnaire with five open questions, answered by 147 students from the early periods of degrees in Chemistry at Universidade Federal do f Rio Grande do Norte. The answers revealed uncertainty on the part of students, both conceptual and representation, with superficial justifications, always using the octet rule to describe models of chemical bonds. Results suggest that these students had inadequate training in high school and that the examinations for entrance into the ranks were made according to flexible criteria less demanding in terms of knowledge. These observations have led to the conclusion that for future changes, it is necessary for high schools and in the early periods in universities favoring the adoption of pedagogical approaches in context and applying strategies to overcome the teaching of superficial memorization on Chemical Bonds, which probably have applied to the teaching of other subjects of chemistry

In today`s society the use of so-called information technology and communication (ICT), is promoting a revolution in the forms of teaching and learning through the methods of distance learning courses, especially in higher education. Studies show that students in this way have great difficulties in the learning process, especially when dealing with experimental subjects that require high power of abstraction as chemistry. The goal of this work is to promote improvement in the teaching and learning in the discipline Chemistry of Life offered for the Bachelor`s Degree in Chemistry in distance UFRN. For this we analyzed evidence of the semester 2011.2, in order to identify what are the main difficulties of the students on the assessments. That`s why video lessons related to matters that create the majority of difficulties for students were developed, the final product this work. Being obtained the improvements by video classes in the learning process of the students, from a questionnaire answered by the students in the virtual learning environment, and from their success rate at the end of the course

Considerando o papel do ensino superior em saúde para a sociedade brasileira, em que os egressos dos cursos ofertados na área serão os profissionais prestadores de serviços à população, este estudo objetivou analisar o componente ensino do PET-Saúde da Família - Natal-RN na formação de estudantes dos cursos de graduação em saúde da UFRN. Foi realizada pesquisa qualitativa com análise de documentos das disciplinas SACI e POTI datados entre 2009 e 2011 (portfólios, avaliações de desempenho e oficina de avaliação), mediante o auxílio do software Alceste© e análise de conteúdo, segundo Bardin. Na análise foi encontrado como potencialidades: o alunato trabalhando em grupo tutorial multidisciplinar, cuja interação e contato com a Unidade de Saúde da Família, incluídos os profissionais, bem como a comunidade, instiga nos aprendizes o diálogo consigo mesmo e com o outro, numa construção dos ser/agir no mundo. Os textos trabalhados durante as aulas permitem refletir e teorizar a respeito da realidade observada, auxiliando-os na identificação dos problemas e no traçar estratégias de intervenção. Já a observação da realidade reveste o aluno de humanização. Este passa a captar as necessidades e dificuldades enfrentadas pela comunidade observada. Nas fragilidades ficaram evidenciados: problemas de relações interpessoais entre os estudantes da SACI; a maioria dos projetos de intervenção ocorrendo numa perspectiva paternalista, reproduzindo o modelo de prestação de serviços na saúde mais praticado nas sociedades brasileiras; dificuldades em aprofundar no aprendiz, a importância da teorização dos assuntos; problemas de financiamento de projetos de intervenção; descumprimento do plano de ensino em alguns grupos tutoriais; e, por fim, dificuldades dos alunos e monitores em acompanhar as atividade de pesquisa e extensão do PET-Saúde, pela falta de integração dos projetos pedagógicos dos cursos. Conclui-se que o componente ensino do PET-Saúde da Família adota metodologias ativas de ensino na inserção de alunos na Atenção Primária em Saúde, proporcionando uma formação dentro de princípios éticos e humanísticos a partir do trabalho em equipe e da inclusão reflexiva dos alunos na Estratégia Saúde da Família. Apesar da existência de fragilidades concernentes às relações interpessoais, descompasso entre as proposições multiprofissionais e interdisciplinares da SACI e POTI e as dificuldades de pô-las em prática em currículos fragmentados e organizados por disciplinas pouco flexíveis, potencialmente, ao fim dessas experiências conectadas a Atenção Primária, os discentes apresentam uma nova visão do cuidado com a saúde, próxima às necessidades da população, iniciando uma tomada de postura crítica e reflexiva, entendendo-se com sujeitos ativos no construir a saúde coletivamente

This dissertation aims to analyze the strategy of socio Intervivência University Project OASIS training of community development from the perspective of social entrepreneurship. This project was part of the context of a sort of university extension, called Intervivência University, which emerged in 2008 through the announcement MCT / CNPq / CT-Agribusiness / MDA - No. 23/2008 - Intervivência University Program. With the analysis of the OASIS project sought to identify a strategy socio, which was used elements of popular education and aimed to develop young people within the social entrepreneurship that made contributions to such has taken actions in their communities seeking range of social gains. For this, the methodological aspect, it was used in the research, a qualitative approach, case study, content analysis, semi-structured interviews and non-participant observation. In the theoretical aspect was addressed in the affairs of: social entrepreneurship, with emphasis on the concept, their differentiations of business entrepreneurship and social responsibility, and characterizing the social entrepreneur, popular education, as for the development of social entrepreneurship is the need for a new way of thinking and seeing reality for the people, and youth leadership, given the importance in the context of social action, to have young people seeking a better life for their communities. Addressed the theory were drawn categories (capital, empowerment and youth participation) and subcategories of analysis (value, attitude, behavior, trust, cooperation, civic participation) used in this work. Given the information and analysis of interviews and observations could be perceived that the strategy promoted socio Project OASIS changes, or the reaffirmation of values, resulting in new attitudes and, consequently, new behaviors in the students interviewed. Has been identified in them the development of trust and cooperation. In the aspect of civic awakening was observed in some of them only. In relation to juvenile activity was perceived to develop actions aimed at social benefits for all respondents. Thus, the OASIS Project Intervivência University made contributions to the young participants in the research aspect of social entrepreneurship, influencing them in developing activities in the social sphere in which cities are embedded

In the design of a building process must consider climatic variations in the region, the external conditions and the use of available resources in nature, like the sun, vegetation, rain and winds, to provide a built environment with comfort and environment reduced energy expenditure. However, increasing urbanization, often with an occupancy of disordered ground comes disregarding this knowledge and disregarding local characteristics, drastically reducing the green areas. This disordered occupation associated with the reduction of green spaces, is modifying aspects of climate and thus, damaging the thermal comfort of users. Given this situation was born the question: What projetuais strategies can bring better thermal conditions to an educational building located in a region of hot and humid weather? Thus, faced with two important issues , education and environmental comfort , the research is justified by the fact that there is a large national demand for expansions and renovations in its public schools , but not in most areas provides students with quality for good learning development. This paper aims to draw up a project for establishment of Primary Education with the application of the concepts of bioclimatic, highlighting the use of vegetation as a regulatory element of the climate. Initially we carried out a literature search; we analyzed architectural solutions and set up the site. The next phases, called understanding, were raised with the laws, rules and environmental restrictions. Subsequently, the program needs and the development of architectural design was defined. The conclusion of this paper presents the definition of criteria and solutions for the use of vegetation to design of bioclimatic architecture in hot and humid climates and contributes a catalog of plant species for schools in the metropolitan region of Natal, RN.

In this dissertation we propose a Teaching Unit of Physics to teach content through environmental discussions of the greenhouse effect and global warming. This teaching unit is based on a problem-methodological intervention from the application of the method of the Arch of Charles Maguerez. The methodological foundations of the thesis are embedded in action research and this is structured in five chapters: the first chapter deals with the Physical Environment (FMA) as a subject in Degree Courses in Physics in Brazil, bringing the concern of how this discipline has been taught. We started the first chapter explaining the reasons behind the inclusion of the discipline of Physical Environment in a Physics Degree Courses. Then we did a search on the websites of Institutions of Higher Education, to know of the existence or not of this discipline on curricular. We then analyzed the menus to see what bibliographies are being adopted and what content of Physics are being worked, and how it has been done. The courses surveyed were those of Federal and Federal Institutes Universities. Thus ended the first chapter. Given the inseparability between studies in Physics Teaching and studies on competencies, skills and significant learning, wrote the second chapter. In this chapter we discuss the challenge of converting information into knowledge. Initially on initial teacher training, because even if this is not our focus, the study is a discipline on the upper reaches, therefore, offered to future teachers. Then we talked about the culture of knowledge, where we emphasize the use of a teaching approach that promotes meanings taught by content and make sense to the student. We finished the third chapter, making some considerations on skills and abilities, in order to identify what skills and competencies were developed and worked during and after the implementation of Curriculum Unit. The third chapter is the result of a literature review and study of the radioactive EarthSun interaction. The subjects researched approach from the generation of energy in the sun to topics stain solar coronal mass ejections, solar wind, black body radiation, Wien displacement law, Stefan-Boltzmann Law, greenhouse effect and global warming. This chapter deals with material support for the teacher of the aforementioned discipline. The fourth chapter talks about the arc method of Charles Maguerez; Here we explain the structure of each of the five steps of the Arc and how to use them in teaching. We also show another version of this method adapted by Bordenave. In the fifth and final chapter brought a description of how the method of Arc was used in physics classes of Environment, with students majoring in Physics IFRN Campus Santa Cruz. Here, in this chapter, a transcript of classes to show how was the application of a problem-based methodology in the teaching of content proposed for Physics Teaching Unit from the environmental discussion about the greenhouse effect and global warming phenomena

The Brazilian Northeast has been a constant subject for journalists of one of the world's leading media companies - The New York Times - between 1933 and 1945. This time, the US government implemented a new foreign policy for Latin America - known as the Good Neighbor Policy. It preached, various points including more respect and attention to the countries south of U.S. borders. Because of her geostrategic importance, Brazil was one of the countries that received the most attention of the bureaucracy and American press. This study investigates the multiple Northeast representations formulated in The New York Times' pages when the Americans were spotlight is on the region. It delineates similarities and differences between the NYT, the press and the governments of the United States and Brazil from the ways of conceiving this particular part of Brazil. Through the analysis of texts, photographs and maps, it is dedicated to establish connections between spaces, press and politics of the 1930s and 1940s. These decades there were relevant changes in the political landscape of both countries that permeated the news, reports and articles of NYT. Circumstances such as the 1935 armed uprisings - known as Communist Conspiracy - the installation and operation of the New State, and especially the Brazilian and US participation in World War II and the bilateral negotiations on the installation of US bases in Brazil were cardinal for the various Northeast images that circulated in the publication. The region was repeatedly subject of correspondent of the New York newspaper in Brazil, Frank M. Garcia, but also present on matters of professionals responsible for various sections: review of books, publishing, tourism, foreign affairs, etc. Along the investigated period, the visions of the region made in the articles published in the newspaper that suffered major metamorphoses. Starting with Northeast of the drought, famine and death recurrent in Brazilian literature to the most dangerous point for hemispheric defense, passing through representations of the American West lawless nineteenth century and the Latin America marked by the dominance of exotic nature and stagnation, a space to be transformed by the US technical knowledge.

The trophic ecology studies issues related to the diet of individuals within a community .The relation between the body size of the predator and the prey size, individual specialization and niche breadth are some of the issues that can be discussed by it .I collected the lizards using pitfall trap, glue and active collecting traps in a fragment of Caatinga. The most common species in this community were Tropidurus hispidus, T. semitaeniatus and Cnemidophorus ocellifer. The visits to the farm also relied on collecting invertebrates at each season to understand how the nutritional resources of lizards were presented in each one of them. I tried to answer some questions : 1) If there was a positive relation between body size of the predator and the size of prey of the community ; 2) If in different seasons the relation of body size of the predator and the maximum and/or minimum size of the prey would be positive ; 3) If species with different foraging strategies have positive relation on the size of the predatorprey relation; 4) If the seasonality would influence on the individual expertise of lizards community and more common species; 5) If the breadth of the niche would be influenced by seasonality ; 6) If more individuals with different morphology between them would present less similar diet. I found that there was indeed a positive relationship between size of prey and predator, but nonexistent related to the minimum size of prey; Among the seasons relative size of predators and prey was different for the maximum and minimum size, but was positively related only to the size of the maximum prey. And comparisons between different foraging strategies had the maximum and minimum line inclination greater than zero and different from each other; individual specialization was not influenced by seasonality and the niche breadth was wider in the dry season only to T. semitaeniatus. At last I didn't find a significant negative relationship between morphological dissimilarity and similarity of diet.

But, this study also has the desideratum to understand the citizen's role in public life, especially in the sphere of the Executive Branch, in order to actualize the Fundamental Right to a just, efficient and honest Public Administration. Thus, to achieve this necessity, the proposal is to expose the thought of the classic contractualist thinkers, Thomas Hobbes, John Locke and Rousseau about the legitimacy of governments, through the statutes, and the question of the general will and majority rule as well as how to present the comments of Thomas Jefferson on popular sovereignty and dialogical citizen participation in matters of local interest.

On the other hand, the fundamentality of management also covers the aspect of the development of cities, which decisively affects the development of man, who, to join a deliberative governance program, needs to be politicized, adopting full participation and dialogue as a citizen responsibility. Furthermore, taking as the major heart, it will be presented the doctrine of Jürgen Habermas whose Discourse Theory element is to be followed for the implementation of a broad deliberative and emancipatory democracy, with effective citizen participation. It will also be considered the Condorcet Constitution Project as a comparative link in the linking of the public deliberative will, and the Central Power, in the face of the Theory of “Sluice” Habermas. The proposal, based on communicative action, must allow a continuous flux and influx process of social interests towards the exercise of administrative power. The dialogical deal, brought to the center of the decisions, will allow discussions in the public scope, and may contribute to the legitimacy of government actions, inasmuch as it creates the feeling of politicization demanded by the man in a democratic state.

Esta dissertação analisa um programa jornalístico da TV Universitária do RN e sua possível contribuição para a formação cidadã. O objetivo principal é analisar se o telejornal TVU Notícias contribui para a formação cidadã dos seus telespectadores, a partir das escolhas dos assuntos e da angulação das matérias exibidas no programa. Busca-se compreender os princípios, os conceitos e as práticas do jornalismo público, movimento formado por um grupo de jornalistas norte-americanos que pretendiam recuperar a ética e os princípios democráticos no processo de formulação de notícias. Pretende-se apresentar e analisar o jornalismo público como uma forma possível de desenvolver a cidadania e verificar se os conceitos que conduzem este tipo de jornalismo podem ser encontrados no jornalismo da televisão pública brasileira. Para consecução do objetivo deste trabalho, foi realizada pesquisa bibliográfica acerca do jornalismo público, da evolução do jornalismo, dos efeitos da mídia e do conceito de TV pública. Foi, também, realizada pesquisa empírica através da observação do processo de produção do programa, relacionando-se as matéria/pautas, revendo-se os arquivos dos textos das matérias, e para complementar o estudo assistiu-se os áudios das matérias gravados em mídia DVD. A análise envolveu 12 programas e 12 matérias veiculados no período de 2009 a 2014. Os resultados da pesquisa permitiram constatar que a amostra das notícias apresentadas no programa sugere que os assuntos agendados são, em sua maioria, de interesse público e valor social, mas carecem de mais contextualização, profundidade e pluralidade de fontes. A partir desses resultados e tendo como diretriz o papel e a função da TV pública, concluiu-se que para o TVU Notícias possa contribuir efetivamente para a formação de seus telespectadores precisa superar a superficialidade das matérias apresentadas, aproximando-se mais do jornalismo que se espera de uma TV pública.

Antonin Artaud (1896-1948) est un poète, acteur, dramaturge et écrivain français né à Marseille, mais dont la vie artistique se développe principalement à Paris. Artaud est l'auteur de la notion bien connue de Théâtre de cruauté, qui inspire encore aujourd'hui de nombreux groupes de théâtre dans différents coins du monde. Il a écrit sur le théâtre, la poésie, l'art, la philosophie, entre autres. De 1924-1935 est également dédié au cinéma, à la fois dans son théorique et pratique. Une étape un peu inconnu et peu exploré dans sa vie. Elle a joué dans 22 films avec certains des réalisateurs les plus importants dans le monde, et a laissé huit scénarios, dont un seul a été realizé, et huit écrits théoriques sur le cinéma. Cette thèse cherche à examiner précisément cette période insuffisamment étudié dans sa carrière, à partir de trois questions initiales: Artaud développé un sens de la cruauté au-delà du théâtre? Nous pouvons penser à la culture de la cruauté envers les films, en d‘autres termes, un cinéma de la cruauté ? Nous pouvons penser sur le sujet contemporain de cette culture? La réponse à ces trois questions est oui. L'idée de la pensée de la cruauté au cinéma est intervenue concomitamment à leurs expériences et élaborations de ce qu'il a appelé Théâtre de la cruauté. Les deux réflexions sont donnés concomitamment et de manière récursive. Plus que cela, toutes ses productions artistiques, dont la poésie et la peinture, ont été traversés par la notion de cruauté. Nous concluons que leurs élaborations sur un cinéma de la cruauté a eté interrompu au moment même que le développement technique a souligné la possibilité de sa réalisation. De plus, à l'enquête de son travail, nous pouvons voir que presque toute sa pensée a été préparé sous les images, de sorte que nous pouvons même parler d'une pensée cinématographique d‘Antonin Artaud. En conséquence, nous ne concevons pas sa théorie au septième art comme secondaire à leurs intérêts, comme le rapporte la plupart de ses commentateurs, mais absolument essentiel dans le développement de ses écrits, qui jusqu'à maintenant accumulé plus de deux mille pages. En outre, Artaud ne pense pas l'art pour l'art, mais seulement comme un dialogue fructueux et intensif avec l'homme et la culture. L‘art était l'instrument privilégié de proposer un diagnostic et une nouvelle façon de voir la société contemporaine. À travers le film il a imaginé la possibilité d'une reprise de forces éthico-esthétique-politiques perdus sous les décombres de la civilisation occidentale. L'établissement d'une nouvelle relation avec l'image, le sujet de la (post-) modernité pourrait sauver une puissance esthétique du corps et de la pensée que, réinterprété, agiraient envers eux-mêmes et le monde à réinventer.

In view of the climate of instability and deep social inequalities, it has been evident in the Brazilian reality, a new way to punish systematic already developed and consolidated in other countries, in which, among other things, the criminality is anticipated only by danger that the individual sports. It appears, therefore, that the theory developed by Günter Jakobs, nominated Criminal Law of the Enemy, became subtly inserted in the Brazilian reality as well as in international relations signed. In this sense, the Brazilian State, in order to carry out the international legal cooperation in the criminal field, signed a mutual assistance agreement with the government of the United States of America. Forward the conclusion of Mutual legal Assistance Treaty (MLAT), the signatory countries voiced a desire to cooperate in order to facilitate the implementation of tasks of the authorities responsible for law enforcement in both countries, comprising research, investigation, prosecution and prevention of crime, said internalized adjustment in the Brazilian legal system by means of Decree No. 3810 of 02 May 2001. Alongside these considerations, the present study aims to analyze the Criminal law of the Enemy today, seeking to find evidence of that theory in the MLAT, international legal cooperation instrument signed between the government of the Federative Republic of Brazil and the government of the United States of America. Moreover, it has the objective to describe its effects on the Brazilian jurisdiction, especially as concerns the relativity and the suppression of human rights. Once done the introit, analysis will be carried out in the first chapter, on the definition and main features of the theory of Criminal Enemy of the law, it is imperative to approach the humanistic aspect that preceded the theory as well as the dealings given to some controversial issues surrounding it, such as the anticipation of the enemy's punishment and the disproportionality of the penalties imposed. In the second chapter will present the conceptual assumptions, historical evolution and the positives aspects, as well as the barriers and the pursuit of effectiveness of international legal cooperation. In the chapter, bedroom effective analysis of specific modality of cooperation will be held, the Mutual legal Assistance Treaty - MLAT in criminal matters, signed between the Federative Republic of Brazil and the United States of America, in which the general aspects will be addressed and the MLAT reflections on the Brazilian jurisdiction, which includes analysis about the relativity or suppression of human rights, future trends and creating stricter laws, followed by the presentation of the seized conclusion on the subject, in which, among other approaches, will be voiced understanding about the unconstitutionality certain service requests that, from these, there is the bad use of the agreed instrument.
