(Brasil, 2002), demandam corpos normalizados em um padr?o heteronormativo e que efeitos t?m sobre as personagens. Tomo como metodologia a an?lise do discurso, de inspira??o foucaultiana. As an?lises ser?o realizadas por meio das falas, as cenas, dos sons, das imagens, nas coisas expl?citas e silenciadas. Bem como, os conceitos de curr?culo, g?nero, homofobia, heteronormatividade, norma, discurso, rela??es de saber-poder e processos de subjetiva??o e posi??es de sujeito foram eleitos como ferramentas te?rico-conceituais para essa pesquisa. Em termos te?ricos, esta disserta??o se inscreveu no campo dos Estudos Culturais, na vers?o dos estudos p?s-cr?ticos de curr?culo. Assim, o conceito central da investiga??o ? curr?culo, compreendendo-se que ele ensina modos de ser, pensar e agir ?s pessoas, bem como produz determinados tipos de sujeitos e corpos. Igualmente, o conceito de discurso tem espa?o importante, sendo entendido como "pr?ticas que formam sistematicamente os objetos de que falam" (FOUCAULT, 1986, p. 56). Destaco que o discurso da homofobia circula nos mais diversos espa?os produzindo efeitos sobre os corpos, demandando posi??es de sujeito, seja nos filmes, nas novelas, na escola, na fam?lia, na religi?o, na roda de amig@s. O problema central desta investiga??o ?: como os discursos sobre g?nero, por meio de discursos homof?bicos, t?m demandado corpos normalizados em um padr?o heteronormativo nos filmes em an?lise? Para isso, trago como objetivos espec?ficos: verificar os processos de constru??o de pr?ticas ditas femininas e masculinas nos filmes investigados; registrar quais marcas s?o nomeadas e classificadas como "normais" ?s posi??es de g?nero; identificar quais posi??es de sujeito generificados s?o demandadas e produzidas em atividades cotidianas nos filmes em quest?o; investigar como se expressam as desigualdades de g?nero nos longa-metragens pesquisados; analisar quais mecanismos, t?cnicas e estrat?gias de poder s?o utilizadas no refor?o ? homofobia nessas obras cinematogr?ficas; identificar e analisar poss?veis tentativas de apagamento de marcas homossexuais ou escapes nas personagens dos filmes. O argumento central ? de que h? uma reitera??o do padr?o heteronormativo no curr?culo dos filmes investigados mesmo quando se percebe uma suposta tentativa de romper com padr?es tidos como ideais e normais. Desse modo, soma-se ao discurso homof?bico e heteronormativo, por exemplo, discursos biologicistas, religiosos, psicol?gicos e moralistas, demandando posi??es de sujeito heterossexuais. / Disserta??o (Mestrado Profissional) ? Programa de P?s-Gradua??o em Educa??o, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2017. / The present dissertation analyzes how the homophobic discourses circulating in the curricula of the films "Billy Elliot (England, 2000)", "Carol (United Kingdom / United States, 2015)", "C.R.A.Z.Y. - Madras de Amor (Canada, 2005)" and "Madame Sat? (Brazil, 2002)", demand normalized bodies in a heteronormative pattern and what effects they have on the characters. I take as a methodology the analysis of the discourse, inspired by Foucauld. The analyzes will be carried out through the speeches, the scenes, the sounds, the images, the explicit and silenced things. As well as some concepts ? curriculum, gender, homophobia, heteronormativity, norm, discourse, knowledge-power relations and subjectivation processes and subject positions ? were chosen as theoretical-conceptual tools for this research. In theoretical terms, this dissertation was inscribed in the field of Cultural Studies, in the version of post-critical curriculum studies. Thus, the central concept of research is curriculum, it is understood that it teaches ways of being, thinking and acting to people, as well as producing certain types of subjects and bodies. Likewise, the concept of discourse has important space, being understood as "practices that systematically form the objects of which they speak" (Foucault 1986: 56). I emphasize that the discourse of homophobia circulates in the most diverse spaces producing effects on the bodies, demanding positions of subject, be it in the movies, novels, school, family, religion, the wheel of friends. The central problem of this research is: how have gender discourses, through homophobic discourses, demanded normalized bodies in a heteronormative pattern in the films under analysis? For that, I have as specific objectives: to verify the processes of construction of so-called feminine and masculine practices in the investigated films; Register which brands are named and classified as "normal" to gender positions; Identify which generalized subject positions are demanded and produced in daily activities in the films in question; To investigate how gender inequalities are expressed in the studied films; To analyze which mechanisms, techniques and strategies of power are used to reinforce homophobia in these cinematographic works; Identify and analyze possible attempts to erase homosexual marks or escapes in the characters of the films. The central argument is that there is a reiteration of the heteronormative pattern in the curriculum of the investigated films even when one perceives an alleged attempt to break with patterns considered as ideal and normal. In this way, it adds up to the homophobic and heteronormative discourse, for example, biological, religious, psychological and moral discourses, demanding heterosexual subject positions.

For a long time, frames have been built with traditional materials such as concrete and wood but there are newer, less tested alternatives. Posi-Joist is a new kind of hybrid beam which means that it consists of different materials that work together to form a stronger frame. Posi is a collective name for the different parts of the beam. Because Posi-Joist is a new beam, it hasn’t been tested as much as the more traditional materials. The purpose of this report is to investigate if Posi-Joist is an acceptable frame to use on larger constructions since it hasn't been investigated before. In order to investigate this, a hybrid frame consisting of Posi-Joist beams will be compared to a concrete and a wooden frame. When choosing a material there are different parameters that matter. The different materials will demand different spans, have different environmental impact, and have different costs. To investigate which frame is the optimal choice, different software will be used. Autodesk Revit will primarily be used to draw the frames’ different designs. Frame Analysis and FEM-Design will be used to perform calculations on the strength of the frames. One Click LCA will be used to obtain LCC and LCA. The wooden frame was the most expensive since the concrete frame’s price was just 40 % of the wooden frame's total cost. The hybrid frame’s price was 52,4 % of the wooden frame’s price and was therefore more expensive than the concrete frame but cheaper than the wooden frame. The wooden frame had less environmental impact since it emits 11,2 % of the concrete frame’s emissions. The hybrid frame emits 90 % of the concrete’s total emissions. The hybrid frame can manage the largest spans. The conclusion is that the concrete frame is the best option when it comes to design and price but has the most environmental impact. The wooden frame had the least environmental impact but could not manage compatible spans. The hybrid frame could manage the largest spans but was neither the worst nor the best in any of the other categories.

In other words, this research intends to investigate the merits and demerits of some of the most important theories found in contemporary literature commonly used to explain the aforementioned phenomenon. The methodology select by us to solve the questions raised was the bibliographical review of several studies presented in order to elucidate the problem at hand. The dissertation is divided into five chapters. The first one seeks to demonstrates how this problem was posed by the criminal dogmatics and, consequently, aim to discusses the reasons why a set of notorious proposals defend that the two forms of conduct (omission of the impediment of a result and its production by an action) must receive the same treatment under criminal law. The next three chapters analyze three different theories built around the problem we seek to investigate (material-formal theories, Jakobs theory and Sch?nemann's theory). In each chapter, after characterizing the aforementioned theories, we intend to list the objections commonly made by de doctrine to them and, afterwards, present a set of critical observations. The fifth chapter summarizes the main points discussed in the course of this investigation, concluding that the Sch?nemann's approach is the theoretical perspective that - if nuanced with a formal-material theory - offers us a more plausible and coherent solution for the problems posed by the theory of the position of guarantee. This positioning surely reduces the scope of guarantee of supervision and control of sources of danger only to obligations of insurance in legal traffic (Verkehrssicherungspflichten), denying rescue duties (Rettungspflichten) in the position of guarantee by interference. One of the main conclusions of the research is that the starting point for the solution of the ?problem of equalization? must be an argument based on the idea of similarity. That similarity must be found in the analytical structure that justifies the imputation of the result to both the commission and the omission conducts. / A disserta??o tem como objeto de estudo a problem?tica da equipara??o da omiss?o ? a??o nos crimes omissivos impr?prios (Gleichstellungsproblematik) no direito penal contempor?neo a partir da teoria da posi??o de garantia (Theorie der Garantenstellung). O objetivo ? investigar o fundamento da posi??o de garantia analisando os m?ritos e dem?ritos de algumas das teorias encontradas na literatura contempor?nea para explicar esse fen?meno. A metodologia empregada foi a revis?o bibliogr?fica, com exposi??o e an?lise de diversas propostas de solu??o da problem?tica da equipara??o. A disserta??o est? dividida em cinco cap?tulos. O primeiro deles demonstra a forma como o referido problema se colocou para a dogm?tica penal e discorre sobre as diversas propostas que a doutrina apresentou para tentar justificar que duas formas diversas de conduta (omiss?o do impedimento de um resultado e a sua produ??o por uma a??o) recebessem o mesmo tratamento pelo direito penal. Os tr?s cap?tulos seguintes analisam tr?s propostas completamente diferentes de fundamenta??o te?rica da posi??o de garantia que est?o presentes no direito penal contempor?neo (teorias materiaisformais, teoria de Jakobs e teoria de Sch?nemann). Em cada um desses cap?tulos, ap?s a exposi??o da teoria, apresentam-se as obje??es feitas a ela que foram encontradas na literatura, tomando-se posi??o. O quinto cap?tulo faz uma recapitula??o e s?ntese dos principais pontos tratados ao longo da investiga??o, chegando-se ? conclus?o de que a teoria de Sch?nemann, matizada com uma teoria material-formal ? aquela que oferece uma solu??o mais plaus?vel e coerente para a teoria da posi??o de garantia. Esse posicionamento acarreta a redu??o do ?mbito da garantia de supervis?o e controle de fontes de perigo apenas a deveres de asseguramento no tr?fego jur?dico (Verkehrssicherungspflichten), negando os deveres de salvamento (Rettungspflichten) na posi??o de garantia por inger?ncia. Uma das principais conclus?es ? que o ponto de partida para a resolu??o da problem?tica da equipara??o deve ser um argumento de similitude, o qual h? de ser encontrado na estrutura que justifica a imputa??o do resultado tanto ? comiss?o quanto ? omiss?o.

We sought, therefore, with respect to that outlined proposition, to develop relevant reflections on improper omissive crimes, critically scrutinizing the guarantor sources composed in the Brazilian Penal Code and the kind-of-offense as a whole with regard to the mentioned offenses. In the face of it, we intended to formulate hermeneutical paths and suggestions to legislative reforms aimed at stabilizing instruments for containing the broad punitive spectrum currently at the state's disposal, within the systematic rules presently in force in Brazil, with respect to such behavioral species of criminal offenses. This study adopted as its main conceptual framework in criminal dogmatics the ontoanthropological conception of criminal law, individuated in the critical idea of criminal delict as an offense to legal goods, built mainly by Jos? de Faria Costa and so well-bundled and improved, in Brazil, by Fabio Roberto D'Avila. Both these authors, therefore, represent the main theoretical framework of this thesis, together with the significant contributions of Jorge de Figueiredo Dias. Research shows that improper omissive crimes are not reduced to the category of crimes that require a naturalistic result for its consummation to occur. Therefore, in this sense, we performed an accurate inspection on the formal sources of the position of guarantor, disciplined in the art. 13, paragraph 2, of the Brazilian Penal Code, displaying the various doctrinal guidelines expressed on the national scene on the subject and trying to make a conscientious examination of such sources in the light of the essential principles of the criminal justice system. Thus, little controversies relating to the determination of the type-of-offense of improper omission and the mechanisms for reprehending that criminal type stand out as sharply expressive. In doctrine and in regulatory dynamics of the criminal laws of the countries, it is crucial the guideline that for a person to figure as an active subject of an improper omission crime this person needs to be located in the so called position of guarantor of containment of the event generation. It was an aimof this work to examine the different streams of dogmatics, covering national and foreign doctrines as well as the normative criteria that legislate about the issue, through rigorous examination of comparative law, in order to sow, lex ferenda, suggestions for the Brazilian penal system to satisfactorily address the intricate subject of improper omissive crimes. The investigation took theoretical research as a canon, thereby employing national and foreign bibliographies that underpinned the matter. We used the comprehensive exhibition technique for elucidating different guises on the subject and also the comprehensive normative approach, since regulatory guidelines have been suggested in the field of improper omissive crimes. / Calcada na teoria da prote??o de bens jur?dicos, esta investiga??o, aqui resumida, teve como um dos seus motes esquadrinhar as repercuss?es da conforma??o atual da conjectura penal da ofensividade em seus contornos de les?o e de perigo; tudo sob o especial paralelo com os crimes omissivos impr?prios, em suas poss?veis manifesta??es no sistema jur?dico brasileiro. Pretendeu-se problematizar o modo pelo qual os princ?pios constitucionais t?m sido violados no ?mbito do sistema penal, no dom?nio dos crimes omissivos, de modo particular, na modalidade omissiva impr?pria. Procurou-se, portanto, com rela??o a tal proposi??o esbo?ada, desenvolver apontadas reflex?es pertinentes aos crimes omissivos impr?prios, perscrutando, de forma cr?tica, as fontes de garantidor compostas no C?digo Penal brasileiro e o tipo-de-il?cito como um todo respeitante aos mencionados delitos. Tencionou-se, ? vista disso, entabular caminhos hermen?uticos e orienta??es de reformas legislativas com vistas ? estabiliza??o de instrumentos de conten??o do amplo espectro punitivo que atualmente est? a dispor do Estado, na sistem?tica normativa, presentemente vigente no Brasil, no tocante a tais esp?cies comportamentais de infra??es penais. Este estudo adotou, na ambitude da dogm?tica criminal, como matriz conceitual central, a concep??o ontoantropol?gica do Direito Penal individuada na ideia prec?pua do il?cito penal como ofensa a bens jur?dicos, edificada, sobretudo, por Jos? de Faria Costa, e t?o bem-agasalhada e aprimorada, no Brasil, por Fabio Roberto D?Avila, autores, portanto, que representam o principal referencial te?rico da presente tese, juntamente com os significativos contributos de Jorge de Figueiredo Dias. A investiga??o evidencia que os crimes omissivos impr?prios n?o est?o reduzidos ? categoria dos delitos que pressup?em um resultado natural?stico para que haja a consuma??o. Para tanto, nesse sentido, efetuou-se uma inspe??o acurada acerca das fontes formais da posi??o de garantidor, disciplinadas no art. 13, ?2?, do C?digo Penal brasileiro, exibindo as diferentes orienta??es doutrin?rias externadas no cen?rio nacional sobre o tema, procurando fazer um exame minudente de tais fontes ? luz dos princ?pios indispens?veis do sistema penal. Destarte, sobressaem como agudamente expressivas as questi?nculas atinentes aos delineamentos do tipo-de-il?cito da omiss?o impr?pria e os mecanismos de repreens?o da mencionada esp?cie delituosa. Prima, na doutrina e nas din?micas normativas dos diplomas penais dos pa?ses, a diretiva de que para uma pessoa figurar como sujeito ativo de um crime omissivo impr?prio ? preciso que ela esteja inserta na chamada posi??o de garante de refreamento da gera??o do evento. Foi intuito deste trabalho palmilhar pelas diferentes vertentes dogm?ticas, percorrendo a doutrina nacional e estrangeira, assim como pelos crit?rios normativos disciplinat?rios da quest?o, mediante a dissec??o de direito comparado, com vistas a semear, de lege ferenda, predile??es para o sistema penal brasileiro arrostar satisfatoriamente o intricado tema dos crimes omissivos impr?prios. A investiga??o tomou por c?none a pesquisa te?rica, desse modo, empregando bibliografias nacionais e estrangeiras que alicer?aram a mat?ria. Foi utilizada a t?cnica expositivo-compreensiva para a delucida??o das diferentes roupagens relativas ao assunto e, tamb?m, o m?todo compreensivo-normativo, porquanto tenham sido aventadas diretrizes normativas, na dimens?o dos crimes omissivos impr?prios.

This concept was developed by the author in order to emphasize positive aspects in the phenomenon described by Melanie Klein under the name depressive position; For Winnicott something is lost when we import the psychiatry the term depression to describe an achievement that belongs to the natural ripening process of the human being. To note the progress that Winnicott proposes in his own description of the depressive position were read by means of a critical analysis, the main author of the texts relating to the phenomenon in question, seeking to relate them to his work, that of Melanie Klein as well as the principal authors of these commentators. Winnicott's ideas related to this process, in its broadest and indicating that such a development is an extension of what already done by Klein, feature is that this takes place in a dual (parent-child) relationship, previous, so the complex Oedipus and forms the basis of constructive deed. A crafted hypothesis in this study is that Winnicott, to develop a theory of development, which is described as a function of the ego and its constant tendency towards integration, as well as noting the fundamental importance of the mother-infant relationship, eventually expanding theories that are a function of ID or instinct (both in-phase and positions) and offers the possibility to describe the stage of concern as the time integration of instinctual life, the ability to observe, in health, the development of be constructive, communicative, social - in this context, with the instinctual to his service, the service life of the ego - and, in sickness, provides us with a theory that helps understanding, acting on, and the possibility of prevention, pathologies associated with depressed mood . / Este trabalho, uma pesquisa de natureza te?rica, visa esclarecer as considera??es de Winnicott sobre a fase do concern. Tal conceito foi desenvolvido pelo o autor com o intuito de ressaltar aspectos positivos no fen?meno descrito por Melanie Klein sob a denomina??o posi??o depressiva; para Winnicott algo se perde ao importarmos da psiquiatria o termo depress?o para descrevermos uma conquista que pertence ao processo natural de amadurecimento do ser humano. A fim de notar os avan?os que Winnicott prop?e em sua descri??o pr?pria da posi??o depressiva foram lidos, por meio de uma an?lise cr?tica, os principais textos do autor relativos ao fen?meno em quest?o, buscando relacion?-los a sua obra, a de Melanie Klein bem como dos principais comentadores destes autores. As ideias de Winnicott correspondentes a este processo, em sua caracter?stica mais ampla e, indicando que tal desenvolvimento representa uma amplia??o daquilo j? feito por Klein, ? que este se d? em uma rela??o dual (m?e-beb?), anterior, portanto, ao complexo de ?dipo e constitui a base do fazer construtivo. A hip?tese trabalhada neste estudo ? a de que Winnicott, ao desenvolver uma teoria do desenvolvimento, sendo esta descrita em fun??o do ego e de sua permanente tend?ncia ? integra??o, bem como fazendo notar a import?ncia fundamental da rela??o m?e-beb?, acaba por ampliar as teorias que o fazem em fun??o do id ou do instinto (tanto em fase como em posi??es) e oferece a possibilidade, ao descrever o est?gio do concern como o momento da integra??o da vida instintual, a possibilidade de observarmos, na sa?de, o desenvolvimento do ser construtivo, comunicativo, social neste contexto, com a vida instintual a seu servi?o, a servi?o do ego , e, na doen?a, nos fornece uma teoria que auxilia a compreens?o, a a??o sobre, bem como a possibilidade da preven??o, de patologias associadas ao humor deprimido.

This work had as objective main to identify if a deserving position in its model of leadership exists in the students of Universidade Federal Rural do Rio de Janeiro, from existing intertime exchanges between the leader and its followers, making possible the bond between these and justifying the power of influence of those. For such a research of the descriptive type was carried through. One searched to identify the deserving position of the followers in relation to the leader, to leave of these existing intertime exchanges. It s necessary that the differentiation of the leaders and the controlling, in the companies, either made not only in function of the positions that occupy, but in result of the real capacity that has to influence the people and to give to the collaborator, an eager participant of intertime exchanges, values to which, this can be grasped. This exchange is present in many dimensions of the practical life, without that the people, many times, if give account of this. Always that hand of some thing in the gift in favor of some thing in the future confides, assumes a creditor position, position this based by an idea of sacrifices gifts in favor of future benefits. The leader works with common people and gets resulted extraordinary with these people, therefore she knows that its vision will become reality if the change in that direction will be made with the adhesion and the contribution of each participant of the team. Leadership is a choice, does not want to say position, privileges, headings or money, but, however, means responsibility.

Para tal foi realizada uma pesquisa do tipo descritiva. Buscou-se identificar a posi??o credora dos seguidores em rela??o ao l?der, a partir destas trocas intertemporais existentes. Torna-se necess?rio que a diferencia??o dos l?deres e dos gerentes, nas empresas, seja feita n?o apenas em fun??o dos cargos que ocupam, mas em decorr?ncia da real capacidade que t?m de influenciar as pessoas e dar ao colaborador, um ?vido part?cipe de trocas intertemporais, valores aos quais este possa se agarrar.

Geralmente nestes sistemas, a convers?o de energia solar em el?trica ? realizada por m?dulos fotovoltaicos, instalados em estruturas fixas, com inclina??o determinada em fun??o da latitude do local de instala??o. Neste sentido, o uso de estruturas m?veis, com rastreamento solar, tem possibilitado o incremento da produ??o da energia gerada. Por?m, o desempenho dessas estruturas depende do tipo de rastreador instalado e do tipo de controle de posi??o utilizado. Nesta disserta??o, ? empregada uma estrat?gia de controle de posi??o aplicada a um rastreador solar, que ser? instalado no Laborat?rio de Eletr?nica de Pot?ncia e Energias Renov?veis (LEPER), localizado na Universidade Federal do Rio Grande do Norte (UFRN). O rastreador ser? do tipo polar, com rastreamento di?rio no sentido leste-oeste e ajuste do ?ngulo de inclina??o manual nos per?odos sazonais, no sentido norte-sul
