Murray, Susan. "The Female Social Activist in American Cinema - A New Genre: Norma Rae, Silkwood, Erin Brockovich, and North Country." Scholarly Repository, 2007. http://scholarlyrepository.miami.edu/oa_theses/83.
Full textAbstract:
This thesis proposes that the female social activist is a new genre in American cinema. The four films chosen in this paper: Norma Rae, Erin Brockovich, Silkwood, and North Country are argued to be representative, and form the narrative construct of this genre. The argument uses Stanley Cavell?s theory of genre composition as presented in Pursuits of Happiness: The Hollywood Comedy of Remarriage and Contesting Tears: The Hollywood Melodrama of the Unknown Woman. There is growing recognition in the American film industry that a series of films portraying women as activists addressing social concerns is forming the basis of an emerging new genre. The social concerns addressed in the above films are: environmental pollution and its toxic health effects, sexual harassment of women in traditional male work places, radioactive contamination of nuclear plant workers, and unionization of textile workers. In this genre women are presented in a new social role. Future directions of this work suggest that the female social activist genre can encompass effectively all areas of social concerns as gender is demonstratively not a barrier.

Full textAbstract:
La présente thèse doctorale étude le cinéma homosexuel subversif en Espagne au cours des années soixante-dix et quatre-vingt, envisageant ainsi une catégorie cinématographique inédite jusqu'à présent dans l'historiographie espagnole spécialisée. Ce cinéma est constitué des films de thématique gay et lesbienne qui transmettent des messages dont l'objectif est de transgresser l'hétéronormativité via différentes façons d'extérioriser l'homosexualité, de présenter des identités sexuelles et de genre alternatives ou d'exposer des discours qui remettent en question les tabous sociaux, culturels et politiques relatifs à la sexualité. Pour toutes ces raisons, afin d'étudier cette nouvelle catégorie cinématographique il a été indispensable aussi d'analyser les contextes politiques et culturels dans desquels s'est déroulée l'histoire de l'homosexualité au cours de ces mêmes décenniesThis Thesis proposes the study of Subversive Homosexual Films in Spain during the decades of the Seventies and Eighties. Thus raising a new conematographic category within specialized Spanish historiography. This type of cinema is composed of gay and lesbian themed films which transmit discourses aimed to transgress heteronormativity using different ways of externalizing homosexuality; presenting alternatives gender and sexual identities or by raising messages that challenge social, cultural and politicians taboos towards sexuality. Therefore, for the study of this new filmic categoryin depth; it is essential to analyze the political and cultural contexts in which the history of homosexuality was developed during these decades

Full textAbstract:
Using practice-led research methodologies, ten transgender men, who were at various stages of transition from female to male, were included in this study. The central research output is a feature-length documentary film called It's Not Just Me.
The film project seeks to share the extraordinary and the mundane with specific focus on four individuals who were undertaking testosterone treatment. The aim of this research was to contribute to a wider understanding of the intricacies of gender transition for the individual, and their relationship to their surroundings and to document their agency in a space of perpetual transition.
This research project was prompted by my interest in the way in which transgender men are shaped by, through and disrupt their psychological and physiological being within their established environments. Relationships between self and identity formation framed my primary research and it focuses on the notion of change as it relates to the transgender man’s experience of undergoing gender transition. Issues of individual self-identification/perception and social hetero-normativity as a performative statement were explored.
There were four groups of participants. Ten transgender men were interviewed in the overall study and four of these featured in the documentary film. There were 24 supplementary participants, for example family and friends, who also appeared in the documentary film. In addition, one psychiatrist was interviewed. Thirteen filmmaking technical collaborators also assisted in the making of the documentary artefact.
Methods of enquiry into and through (Frayling, 1993, p. 2) the art practice explored gender and identity formation. The research reviews the practice of filmmaking including investigating various techniques of documentary filmmaking from directing, writing, image capture and post-production. Main filmmaking theorists include Nichols and Aufderheide.
The two main findings of my research are that: first, masculinity is a multi-layered and transitional pursuit and is not a fixed concept for all men, but specifically transgender men, and secondly, film can serve as a vessel in which to understand trans-masculinity from a space of agency and ethical engagement.
This project adds to the extensive body of scholarship locating identity with emphasis to understanding masculinity and gender. It argues that human shifts are a constant process, with specific regard to understanding the transgender male’s transition experience in Perth, Western Australia where all transgender participants reside. The significance of the film and its meanings to the transgender community was profound. This in terms of visibility and the ability to share their personal journeys with an audience was an act of agency in action.
This film as an outcome potentially changes the face and visibility of the transgender man and brings their humanness and experiences to the fore in a positive and collective way. The indirect impact of this work is where its power lies. The film provides a voice to marginalised communities and is fundamentally activist cinema.

Full textAbstract:
O presente trabalho tem como proposta estudar o uso de estruturas documentais no cinema ficcional de horror, tipo de narrativa que ficou conhecida popularmente como found footage. Esses filmes fazem uso de uma linguagem propositalmente híbrida, associando a forma do documentário ao conteúdo da ficção e, hoje, encontram-se tão em voga que já possuem até mesmo clichês e estereótipos. A intenção é entender de que forma o gênero do horror se apropria douso de uma estética associada a registros documentais para favorecer as reações de medo no espectador. Para tanto, privilegiamos recortes na história do cinema e conceitos que possam contribuir para o desenvolvimento de nosso estudo, tanto no que diz respeito ao cinema documental, quanto no que diz respeito ao gênero de horror. Como objeto de análise mais detalhada, trazemos a trilogia inicial de da franquia Atividade ParanormalThis paper aims to study the use of documentary structures in the fictional horror movies, kind of narrative that became known popularly as found footage. These films make use of a purposely hybrid language, linking the form of documentary to fictional content and, today, are so fashionable that already have clichés and stereotypes connected to them.The intention is to understand how the horror genre appropriates the use of an aesthetic associated with documentary records to favor fear responses in the viewer. Hence, we privileged cuts in film history and concepts that can contribute to the development of our study, both with regard to documentary cinema, as with regard to the horror genre. As more detailed analysis of the object, we bring the original trilogy of the franchise "Paranormal Activity"

Zwarich, Jennifer. "Federal Films| Bureaucratic Activism and the U.S. Government Motion Picture Initiative, 1901-1941." Thesis, New York University, 2014. http://pqdtopen.proquest.com/#viewpdf?dispub=3635322.
Full textAbstract:
This dissertation describes the emergence and expansion of U.S. government motion picture work over the first four decades of the twentieth century. It situates the early history of federal filmmaking within the long progressive drive to reshape representative government into a more active proponent of the welfare of its citizenry and argues that despite reigning critiques to the contrary, institutional sponsorship actually gave social meaning and efficacy to this mode of social documentary. Indeed, I argue that U.S. government film production can be understood as a kind of social activism that was simultaneously propelled and limited by the contours of the federal bureaucracy. Envisioning government film work as “bureaucratic activism”—with all the power as well as the inefficiencies, entrenched rigidities, red tape, politics and establishment loyalties implied by the term “bureaucratic”—is useful here. It helps capture the contradictory nature of a pragmatic enterprise that actively and optimistically sought social change from within the confines of the status quo.
Federal films are examined in this history as spaces of complex negotiation— as points of contact between the structure(s) of the American democratic state and the imaginings of progressive bureaucrats about both their relationship to that state and its relationship to its citizens. Relying largely on original research in little-mined federal collections, I argue that the interpretations of social problems and solutions attempted in and by these film texts represent more than attempts to bolster institutional authority and reinforce the status quo (though, of course, they were such attempts). These aims were mediated by a will—evident both within the film texts and in the extemporaneous correspondence of their administrators and producers—to explain or justify such authority claims by literally and figuratively visualizing them as not arbitrary but rather in the interest of nurturing or protecting the common good. Federal films, seen in this way, don’t automatically obviate social change but instead represent attempts to relate social change to the ideal of democratic government. Viewed in the context of the specific change initiatives they were produced to aid, federal films were reflections of and on democratic governance itself.

Este trabalho de pesquisa pretende desenvolver uma análise de cinco documentários realizados pelo cineasta Renato Tapajós, entre 1977 e 1982, em parceria com o Sindicato dos Metalúrgicos de São Bernardo do Campo e Diadema: \"Acidente de Trabalho\" (1977), \"Trabalhadoras Metalúrgicas\" (1978), \"Greve de Março\" (1979), \"A luta do Povo\" (1980) e o longa-metragem \"Linha de Montagem\" (1981). O objetivo é refletir sobre essa experiência de produção de filmes militantes, destinada à educação sindical, durante a Ditadura Militar no Brasil. Para isso, procuraremos identificar como se configura o ponto de vista dos documentários. Partiremos da análise da relação entre as temáticas apresentadas e as diferentes locuções que os filmes articulam, para investigar como o aspecto político e ideológico da representação da afirmação da identidade sindical, de contestação social e de rearticulação do movimento sindical no ABC durante o regime militar é elaborado e organizado. Finalmente iremos relacionar algumas das referidas obras de Renato Tapajós com outros modos de representação do operariado paulista presentes na produção cinematográfica brasileira no fim da década de 70.This research aims to develop an analysis of five documentaries made by filmmaker Renato Tapajós, between 1977 and 1982, in partnership with the Sindicato dos Metalúrgicos de São Bernardo do Campo e Diadema (Metalworkers Union): \"Acidente de Trabalho\" (Labour Accident) (1977), \"Trabalhadoras Metalúrgicas\" (Women Metalworkers) (1978), \"Greve de Março\" (Strike in March) (1979), \"A luta do Povo\" (The struggle of the People) (1980) and the feature film \"Linha de Montagem\" (Assembly line) (1981). For this, we will identify how the point of view configures itself on those documentaries. Based on the analysis of the relationship between the issues presented and the different voices that the films articulate, we intent to investigate how the political and ideological representation of the union identity statement, social contestation and the rearticulation of the union activity on ABC during the military regime was prepared and organized. Finally, we will relate some of these films of Renato Tapajós with other modes of representation from the metalworkers present in São Paulo Brazilian films in the late 70\'s.

Mauduit, Benjamin. "Election, héritage, apprentissage : la transmission chez les pirates dans la culture populaire anglophone." Thesis, Tours, 2017. http://www.theses.fr/2017TOUR2023/document.
Full textAbstract:
Le but de ce travail est d'analyser les représentations des pirates dans la culture populaire anglophone, représentations qui s'inspirent en premier lieu d'un contexte historique et tendent à montrer les pirates comme des révoltés aux prétentions démocratisantes face aux puissances absolutistes, faisant de l'élection un principe maître qui fait écho à différentes visions de l'implication politique des XXe et XXIe siècles. En parallèle se développe la notion d'une attirance inévitable pour la piraterie due aux liens du sang, un héritage qui mène souvent à diverses formes d'hybridation en mettant sans cesse en question les contenus ainsi transmis. Enfin, que l'on parle d'élection ou d'héritage, ce qui est transmis doit être appris, et les modalités de cet apprentissage sont variables bien que s'inscrivant dans un schéma reconnaissable à travers les artefacts culturels examinésThe purpose of this work is to analyze the representations of pirate in English-speaking popular culture, representations whose foremost source of inspiration for such works is a historical context, and they tend to show pirates as rebels with claims to forms of democracy facing absolutist powers, turning election into a major principle that echoes different visions of political involvement in 20th- and 21st-century America. Along this tendency, the notion of an irresistible attraction towards piracy, due to blood ties, is developed into a form of legacy often leading to diverse forms of hybridization endlessly questioning the contents thus transmitted. Finally, whether election or legacy be dealt with, what is transmitted must be learnt, and the modalities of such learning vary even though they are embedded in a pattern recognizable throughout the cultural artifacts under examination

Treveri, Gennari Daniela. "America, the Vatican and the Catholic Church sphere of activity in Italian post-war cinema (1945-1960)." Thesis, University of Warwick, 2005. http://wrap.warwick.ac.uk/79998/.
Full textAbstract:
The thesis examines the extent the means and the degree to which the American and the Vatican's common cultural ideology was expressed in the film industry of post-war Italy (1945-1960). Through a comparative approach of current theories developed on ideology and an analysis of official documents from the Vatican and the United States Department of State, the thesis investigates the decisive role that American production companies played in the development of the Italian film industry and their links to the Vatican. This analysis evaluates how the Italian production and distribution industries satisfied the American political and economic interests. American political and cultural ideology of the post-1945 era, is compared with the Roman Catholic ideology in order to assess how close their cultural propaganda was. This is followed by studies of the roles played by key individuals, such as Giulio Andreotti and institutions such as ANICA and A.G.I.S. involved in formulating the policies and regulations that affected the production and distribution of American and Italian films in the post-1945 era, as well as the involvement of the Roman Catholic Church in this process. The case studies, which make up the remaining part of the dissertation, illustrate the relationship with the theoretical issues raised in its first part and their ramifications in the relationship between the Catholics and Italian and America cinema. The operation of the Centro Cattolico Cinematografico combined with box-office returns allows for the creation of a new analytical technique to be applied, one that has not been utilized in previous studies of Neorealist films and Italian popular cinema. It makes it possible to highlight the cross-currents that existed across different cinematic genres and styles of those American and Italian post-war movies, which were under the Catholic Church's sphere of activity.

Full textAbstract:
Cette thèse est une étude filmique de l'activité de création d'un artiste peintre. Elle vise à expliciter son cheminement intellectuel à travers les techniques et les procèdes mis en oeuvre pour préciser sa vision intérieure et transcrire ses perceptions. Le travail de recherche se présente sous la forme d'une série de cas, qui sont mises en scène organisées par l'artiste autour d'un même thème pictural. Ce thème porte sur l'expression des corps féminins, et s'appuie sur des constats photographiques réalises par le peintre. Pour appréhender le projet de l'artiste et sa manière de signifier, le film montre, d'une part les artifices techniques que le peintre imagine et construit pour mettre en scène son modèle et le photographier, et, d'autre part, la réalisation des esquisses partant de ces constats photographiques. Pour observer plus finement le processus de création, des séquences sont réservées a l'évolution picturale de quelques esquisses suivant les techniques du fondu enchaine et de l'image par image. Cette approche de l'oeuvre en devenir met en relief les hésitations, les choix de l'artiste, informations qui favorisent l'étude des enjeux intellectuels sous-tendus.

Full textAbstract:
AAu cours des cent années qui séparent la naissance du cinéma de son centenaire, le droit a fait preuve, dans une large mesure, de sa capacité d'adaptation aux spécificités de l'art cinématographique. Si l'assimilation par le droit de la dimension artistique de cette technique d'expression mise au point par les frères Lumière a été particulièrement lente, le droit a manifesté, en bien des circonstances, une réelle aptitude à réagir aux diverses évolutions de l'expression cinématographique, tantôt à l'avantage de l'art cinématographique, tantôt à son detriment. De 1895 à 1945, ces relations sont d'abord dominées par l'incompréhension, tant il semble à l'origine difficile pour les juristes d'admettre la dimension artistique de cette activité nouvelle et de l'intégrer dans leur réflexion sur son encadrement juridique. Elles s'affirment ensuite sur le mode de la confrontation, tant il est clair que le droit positif se compose pour l'essentiel de normes de nature à imposer limites et contraintes aux créateurs cinématographiques. De 1946 à 1995, se construit progressivement un nouveau pan du droit du cinéma, résolument protecteur, qui, progressivement, s'attachera à promouvoir la qualiteartistique de la production cinématographique. Mais un certain nombre des protections ainsi instituées par le droit se révèleront n'être à terme que des illusions, tant il est clair que la pérennite du cinéma français est au moins autant, sinon plus, entre les mains des ingénieurs et des cinéastes qu'entre celles des juristes.

Full textAbstract:
Esta dissertação analisa o contexto político dos Estados Unidos e a representação da cidadania entre as décadas de 1980 e 1990. Através de quatro narrativas fílmicas produzidas em Hollywood, são elas: Mississippi em chamas (1988) do diretor Alan Parker; Nascido em 4 de julho (1989) do diretor Oliver Stone; Um dia de fúria (1993) do diretor Joel Schumacher e Clube da luta (1999) do diretor David Fincher, pretendese conduzir o estudo do contexto político do país através dos seus produtos culturais. A primeira narrativa representa problemáticas acerca da segregação racial e a conquista dos direitos civis por negros, tema latente nos anos 1960, que são evocados mediante o contexto de crise desses movimentos sociais e a desarticulação do Estado de bem estar social nos anos 1980. A segunda narrativa representa a experiência do veterano da guerra do Vietnã e o ativismo político oriundo desta experiência, as culturas políticas em efervescência no período, bem como uma leitura que traga um novo lugar de memória para o veterano do Vietnã. A terceira narrativa representa o contexto de crise econômica proveniente do projeto de nação dos neoconservadores e neoliberais que ascenderam ao poder e como resultado de suas políticas houve um aumento da violência urbana, polarização social, bem como a tematização da crise do homem WASP. A quarta e ultima narrativa foi contemporânea de um movimento de diretores e intelectuais afinados com o liberalismo, que se aproximaram da representação da guerra e do sentido de identidade que este fenômeno forja para criticar a postura bélica que os governos anteriores empreenderam, fracassando, pela apropriação conservadora que estas narrativas também proporcionavam, foi visto nos Estados Unidos uma contundente critica aos ideais do American Way of life e neste sentido, Clube da luta é uma destas produções, por trazer em suas imagens elementos da representação da cidadania no período.This dissertation analyzes the US political context and the representation of the citizenship between the 1980s and 1990s. Through four filmic narratives produced in Hollywood, they are: Mississippi Burning (1988), director Alan Parker; Born on the 4 of July (1989), director Oliver Stone; Falling down (1993), director Joel Schumacher and Fight Club (1999), director David Fincher, it is intended to conduct a study of the political context of the country through its cultural products. The first narrative presents the problematic of the racial segregation and achievements of African-American Civil Rights moviment, latent theme in the 1960s, which are evoked by the crisis of those social movements and the disarticulation of the welfare state in the 1980s. The second narrative is about a Vietnam war veteran experience and political activism arising from this experience, the effervescence of political cultures in the period, as well as a reading that brings a new place of memory to the Vietnam veteran. The third narrative represents the context of economic crisis coming from the national project of the neoconservatives and neoliberals who ascended to power and, as the result of their policies, there was an increase in urban violence, social polarization, and the theming of WASP man crisis. The fourth and final story was contemporary of a movement of officers and intellectuals sympathetic to liberalism, which approached the representation of war and sense of identity that this phenomenon forges to criticize the war posture that previous governments have undertaken, failing, for the conservative appropriation these narratives also afforded, it has been seen in the United States a scathing critique of the ideals of the American way of life and therefore, Fight Club is one of these productions, by bringing in its images elements of representation of citizenship in the period.

Après une mise au point bibliographique sur les aspects physiologiques et moléculaires des phytoalexines de la vigne, les travaux ont porté sur le rôle joué par le resvératrol dans l'interaction vigne - Botrytis Cinerea. Dans un premier temps, nous avons mis en évidence l'activité biologique du resvératrol vis-à-vis des conidies de B. Cinerea. Ensuite, nous avons observé le métabolisme du resvératrol par la stilbène oxydase de type laccase de B. Cinerea au niveau des conidies de ce champignon. L'étude du composé majoritairement obtenu par ce métabolisme a conduit à l'identification d'un déhydrodimère du resvératrol isomère de l'e-viniférine. Parallèlement, nous avons montré l'effet éliciteur du chlorure d'aluminium hexahydrate sur la synthèse de resvératrol chez la vigne. Une étude préliminaire visant à comparer l'efficacité de différents éliciteurs de type biotique ou abiotique sur l'accumulation des ARNm de la stilbène synthase a été réalisée.

This study lines up with the goals of the National Project for Teacher Education, Critical Education, New Literacies and Multiliteracies which intend to contribute to Initial and Continuing Education of Foreign Language Teachers. Its goal is to deepen the discussion of theoretical and methodological issues of language under the light of the critical literacies, allowing participants to create critical-reflective attitudes toward the new proposals and their own practices in the classroom. Inserted in this research context, our study aims to analyze the impact of the use of the cinema as a pedagogical tool, in a continuing education course for foreign language teachers (English and Spanish) from public schools. We assume that teaching a foreign language through films motivates the learner, assists in the development of communication skills and stimulates the autonomous learning. In the period of the course (30 hours) we could offer theoretical support to help the teachers to analyze and prepare teaching activities with filmic content. Besides the theoretical assistance, we offer opportunities for interaction and exchange of experience among the participants, so all the prepared activities could be shared and analyzed by the group before being applied in the classroom. The data obtained through questionnaires, field notes and focal groups were analyzed based on the Activity Theory, recognizing that we are all a source of knowledge and we can act collaboratively to expand the construction of meaning. Thus, the protagonists of the research were responsible for each other's learning. Activity Theory is exemplified in three crucial moments of learning: 1) The goal we intent to reach is shown (in the case of this study, the goal was to teach foreign language using the film as a tool), giving a model, encouraging the teachers not to reproduce, but rather to be creative on this model; 2) We describe the instrument's acquisition process, with the constant comings and goings, frustrations and delights that are on the course to achieve the desired goal (time when teachers begin the process of elaboration of didactic activities); 3) the complexity of the task is described, which requires the ability to work in groups (moment of exchange of experiences between teachers about the results of development and implementation of activities). The results of the study indicate that the cinema is a motivating and efficient tool for teaching foreign languages, and the exchange of experiences and interaction fostered among teachers were important in solving problems, contributing effectively to their education, as well as to a significant foreign language teaching.
Este projeto se alinha aos objetivos do Projeto Nacional de Formação de Professores, Educação Crítica, Novos Letramentos e Multiletramentos desenvolvido por diversas universidades brasileiras, com um núcleo sede na Universidade de São Paulo (USP). Uma das universidades participantes é a Universidade Federal de São Carlos (UFSCar), que conta com o projeto Formação inicial e contínua de professores de língua estrangeira sob o enfoque dos multiletramentos e da transculturalidade que visa contribuir para a formação básica e/ou contínua de professores de língua estrangeira. Seu objetivo é aprofundar a discussão sobre questões teórico-metodológicas da linguagem sob a luz dos letramentos críticos, permitindo que os participantes criem posturas crítico-reflexivas a respeito das novas propostas e das próprias práticas em sala de aula. Inserido nesse contexto de investigação, nosso estudo objetiva analisar o impacto do uso do cinema como instrumento didático em um curso de formação continuada para professores de língua estrangeira moderna (inglês e espanhol) da rede pública de ensino, idealizado e ministrado pela professora-pesquisadora. Partimos dos pressupostos de que ensinar língua estrangeira por meio do cinema motiva o aprendente (HARLOW e MUYSKENS, 1994), auxilia no desenvolvimento das habilidades comunicativas (STEPHEN, 2001) e estimula o aprendizado autônomo (FIORENTINI, 2002; GARCIA-STEFANI, 2010). No curso de formação continuada, com 30 horas de duração, oferecemos aportes teóricos e práticos para dar subsídios aos professores para analisarem e prepararem atividades didáticas com conteúdo fílmico. Além do aporte teórico, oferecemos oportunidade de interação e troca de experiência entre os cursistas, de forma que todas as atividades preparadas fossem compartilhadas e analisadas pelo grupo antes de serem aplicadas em sala de aula. Os dados obtidos por meio de questionários, notas de campo e grupo focal foram analisados à luz da Teoria da Atividade (LEONTIEV, 1978, 1981; VYGOTSKY, 1998; ENGESTRÖM, 2009, 2011), que reconhece que todos somos fonte do saber e podemos agir de forma colaborativa para ampliar a construção de sentidos. Dessa forma, os protagonistas da pesquisa foram responsáveis pela aprendizagem uns dos outros. A Teoria da Atividade (TA) é exemplificada em três momentos cruciais da aprendizagem (LEFFA, 2005): 1) Mostra-se o objetivo a que se pretende chegar (no caso desta pesquisa, o objetivo era ensinar LE utilizando o filme como instrumento), dando um modelo, estimulando os professores-alunos a não o reproduzirem, mas, a serem criativos sobre esse modelo; 2) Descreve-se o processo de aquisição do instrumento, com as constantes idas e vindas, frustrações e alegrias que encontram no percurso para alcançarem o objetivo desejado (momento em que os professores iniciam o processo de elaboração dos exercícios didáticos); 3) Descreve-se a complexidade da tarefa, que exige a capacidade de trabalhar em grupo (momento de troca de experiências entre os professores-alunos sobre os resultados da elaboração e da aplicação das atividades). Resultados do estudo indicam que o cinema atua como instrumento eficaz e motivador para o ensino de língua estrangeira; e a troca de experiências e a interação promovida entre os professores participantes foram importantes na resolução de problemas, contribuindo, efetivamente para sua formação continuada, bem como para o ensino significativo de línguas.

Straube, Wibke. "Trans Cinema and Its Exit Scapes : A Transfeminist Reading of Utopian Sensibility and Gender Dissidence in Contemporary Film." Doctoral thesis, Linköpings universitet, Tema Genus, 2014. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-110049.
Full textAbstract:
Trans Cinema and its Exit Scapes offers a critical and creative intervention into cultural representations of gendered body dissidence in contemporary film. The study argues for the possibility of finding spaces of “disidentification”, so-called “exit scapes” within the films. Exit scapes disrupt the dominant cinematic regime set up for the trans character, which ties them into stories of discrimination, humiliation and violence. In Trans Cinema, for instance films such as Hedwig and the Angry Inch (2001), Transamerica (2005), Romeos (2011) and Laurence Anyways (2012), scenes of singing, dancing and dreaming allow a different form of engagement with the films. As argued here, they allow a critical re-reading and an affirmative re-imagining of trans embodiment. The aim of this study is to investigate the utopian and hopeful potential within Trans Cinema from a critical transfeminist perspective. While focusing in particular on trans entrants as “spectators” or readers, this study draws on the work of a wide range of feminist and cultural scholars, such as Sara Ahmed, Susan Stryker, José Esteban Muñoz, Trinh T. Minh-Ha, Karen Barad and Donna Haraway. The thesis etches out cinematic spatiotemporalities that unfold possibilities of utopian worlding and trans becoming through a set of conceptual innovations. By utilising a critical approach to audio-visuality and feminist film theory, the thesis re-conceptualises haptic spectatorship theory and its critique in western modernist ocularcentricism through a set of conceptual innovations. The methodological tools developed in this thesis, such as the “entrant”, the “exit scape” and “sensible cinematic intra-activity”, feature here as a multisensorial methodology for transdisciplinary transgender studies and feminist film theory as well as visual culture at large.Trans Cinema and its Exit Scapes är en kritisk och kreativ intervention med fokus på kulturella representationer av kroppar som bryter mot en könsbinär ordning i samtida film. Studien argumenterar för möjligheten att hitta utrymmen för “disidentification”, så kallade “exit scapes” inom filmerna. Exit scapes stör den dominanta filmiska ordning som skapats för transkaraktären, en ordning som är förbunden med berättelser om diskriminering, förödmjukelse och våld. Inom Trans Cinema, i filmer som exempelvis Hedwig and the Angry Inch (2001), Transamerica (2005), Romeos (2011) and Laurence Anyways (2012), öppnar scener med sång, dans och drömmar upp för andra former av engagemang med filmerna. Som det argumenteras för i avhandlingen tillåter dessa ett kritiskt omformulerande av, och ett nytt affirmativt sätt att föreställa sig, transkroppslighet. Syftet med den här studien är att undersöka den utopiska och hoppfulla potential som finns inom transfilm utifrån ett kritiskt transfeministiskt perspektiv. Även om studien främst riktar sig till trans entrants som “åskådare” eller läsare, så har den en bred teoretisk bas hämtad från verk av en lång rad feministiska forskare inom kulturfältet, såsom Sara Ahmed, Susan Stryker, José Esteban Muñoz, Trinh T. Minh-Ha, Karen Barad och Donna Haraway. Denna avhandling skissar filmiska spatiotemporaliteter, vilka öppnar för möjligheter av utopiska värdsliga och transsubjektiva tillblivelser genom utvecklandet av olika teoretiska begrepp. Genom ett kritiskt förhållningssätt till audiovisualitet och feministisk filmteori, revideras och omformuleras haptisk åskådarskapsteori och dess kritik i en västerländsk okularcentrism genom olika teoretiska innovationer. De metodologiska verktygen som utvecklas i avhandlingen, såsom “the entrant”, “the exit scape” samt “sensible cinematic intra-activity” utgör här funktionen som multisensorisk metodologi för transdisciplinära transstudier, feministisk filmteori samt för visuell kultur i stort.

Full textAbstract:
Le fractionnement au pressurage, étape clé de la méthode champenoise, et le type de pressurage, conditionnent de façon significative la composition biochimique du moût et du vin. Le pressurage est fractionné en séparant les premiers moûts extraits, qui constituent la "cuvée", et qui proviennent de la pulpe, partie la plus riche en sucre et en acides (tartrique et malique), des volumes suivants, appelés "tailles", qui sont aussi riches en sucre, en sels minéraux (potassium notamment) et en matières colorantes mais moins acides. Les moûts ont des caractéristiques analytiques bien spécifiques. L’évolution de la composition des moûts au cours du pressurage et la mesure des principaux paramètres analytiques permettant de juger de la qualité de l’extraction ont fait l’objet de quelques études (Valade et Blanck, 1989; Blouin, 1998) sur la base d’un fractionnement volumétrique répondant à un cahier des charges champenois. Toutefois, aucune étude portant sur un large nombre de paramètres, dont les propriétés moussantes, n’avait été entreprise avant ce travail de thèse.Une contamination du raisin par le champignon pathogène Botrytis cinerea (pourriture grise) et l’effet de la maturité du raisin, autres paramètres clés dans l’élaboration du Champagne, ont un impact sur la qualité et la composition des moûts et des vins de base et notamment sur les compositions protéique, polysaccharidique et oligosaccharidique. Les essais ont été réalisés avec 2 pressoirs différents : un pressoir pneumatique industriel (capacité 8000 kg) et un pressoir de laboratoire (capacité 6 kg). Ce travail a été réalisé sur deux cépages : Pinot meunier (millésimes 2013 et 2015) et Chardonnay (millésimes 2014 et 2015). Les analyses suivantes ont été réalisées sur les moûts et vins de base : (i) paramètres œnologiques classiques des moûts et des vins, (ii) isolement et analyse des polysaccharides et oligosaccharides solubles des vins de base, (iii) quantification et identification des protéines solubles des vins de base, (iv) mesure de l’activité protéasique des vins de base (impact de Botrytis cinerea), (v) comparaison de la composition des moûts et des vins issus de raisins sains de deux millésimes : 2013 (pressoir industriel) et 2014 (pressoir de laboratoire).La connaissance de l’état sanitaire et l'optimisation du choix de la date des vendanges en fonction de la maturité sont des outils à la disposition de l’œnologue qui lui permettent d’améliorer la qualité des moûts produits au cours du pressurage et par conséquent celle des vins qui en sont issus. A la suite de cette approche, il serait intéressant de voir dans quelles conditions ces paramètres pourraient être reproduits à grande échelle pour une application industriellePress fractioning is a key step in the Champagne method, and the type of pressing will significantly determine the biochemical composition of the juice and the wine. The first pressed juice obtained in the fractioned pressing cycle, called the “cuvée”, is rich in sugar and acids (tartaric and malic). The second pressed juice, called the “tailles”, is as rich in sugar, mineral salt (potassium in particular) and colorant materials as the first one but less acidic. Must has specific analytical characteristics. The evolution of composition in the must during the pressing cycle and the measure of current analytical parameters, allowing the understanding of grapes extraction, have led to little studies in the Champagne region (Valade et Blanck, 1989; Blouin, 1998). These studies have followed the changes between the Cuvée and the Tailles, according to the rules applied for Champagne production. Nevertheless, no study had considered a large number of parameters, including the foaming properties, before this thesis.The contamination of grapes by the pathogenic Botrytis cinerea (gray mold) and the effect of grape maturity, which are other key parameters in the elaboration of Champagne, have an impact on the quality of must and base wine, especially on proteins, polysaccharides and oligosaccharides. The essays were carried out in two different presses: an industrial automatic press (capacity 8000 kg) and a laboratory press (capacity 6 kg). This study was made on two grape varieties: Pinot meunier (vintages 2013 and 2015) and Chardonnay (vintages 2014 and 2015). The following analyzes were effectuated on must and base wine: (i) determination of current oenological parameters of must and base wine, (ii) isolation and analysis of soluble polysaccharides and oligosaccharides in base wine, (iii) analysis, quantification and identification of soluble proteins in base wine, (iv) quantification of protease activity in base wine (the impact of Botrytis cinerea), (v) comparison of composition of must and base wine from healthy grapes of two vintages: 2013 (industrial press) and 2014 (laboratory press).The knowledge of the sanitary state and the optimization of the harvest date are tools used by oenologist to improve the quality of must, obtained during the pressing cycle, and therefore of wine elaborated from them. Following this study, it could be interesting to examine in which conditions these parameters may be reproduced at a bigger scale for forward industrial applications

Ce travail a pour point de départ une analyse quantitative de l’objet »storyboard » faite sur un large corpus. La taxinomie ainsi établie, croisée avec une approche qualitative, nous permet de mettre en lumière des codes de communication et des invariants inhérents à ce dispositif de pré-production. Cela aboutit, dans un premier temps, à la définition de l’outil storyboard parmi les autres dessins de préparation cinématographique. Le classement des données en fonction de leur période apporte ensuite une perspective nouvelle à l’analyse : c’est par l’objet, trace de sa propre histoire et vecteur de pensées, que se dessinent les interactions sociales et la professionnalisation de ceux qui le confectionnent. L’étude porte sur deux conceptions différentes de la pratique du storyboard, d’un côté et de l’autre de l’AtlantiqueThe starting point of this work involves a quantitative analysis of the object »storyboard » applied on a large corpus. The taxonomy here established, crossed witha qualitative approach, allows one to reveal communication codes and invariantsinherent to this preproduction device. This first leads to the definition of the toolstoryboard among other film preparation drawings. The classification of the dataaccording to its period then brings a new perspective to the analysis: it is through theobject, vestige of its own story and vector of ideas, from which are drawn the socialinteractions and the professionalization of those who manufacture it. The studyconcerns two different conceptions of the storyboarding practice, on both sides of theAtlantic Ocean

Full textAbstract:
Detecting suspicious or unauthorized activities is an important concern for High-Performance Computing (HPC) systems administrators. Automatic classification of programs running on these systems could be a valuable aid towards this goal. This thesis proposes a machine learning model capable of classifying programs running on a HPC system into various types by monitoring metrics associated with different physical and architectural system components. As a specific case study, we consider the problem of detecting password-cracking programs that may have been introduced into the normal workload of a HPC system through clandestine means.
Our study is based on data collected from a HPC system called DAVIDE installed at Cineca. These data correspond to hundreds of physical and architectural metrics that are defined for this system. We rely on Principal Component Analysis (PCA) as well as our personal knowledge of the system to select a subset of metrics to be used for the analysis. A time series oversampling technique is also proposed in order to increase the available data related to password-cracking activities. Finally, a deep learning model based on Temporal Convolutional Networks (TCNs) is presented, with the goal of distinguishing between anomalous and normal activities.
Our results show that the proposed model has excellent performance in terms of classification accuracy both with balanced (95%) and imbalanced (98%) datasets. The proposed network achieves an F score of 95.5% when training on a balanced dataset, and an AUC-ROC of 0.99 for both balanced and imbalanced data.

Full textAbstract:
Cette thèse a pour objet la catégorie de cinéma social telle qu'elle a été définie dans la deuxième moitié des années 1990 et dans les années 2000 par des critiques cinématographiques, des chercheurs en sciences sociales et des militants proches des mouvements antilibéraux. Ces différents acteurs de la médiation et de la réception ont regroupé sous ce label des films français mettant en scène des personnages membres des classes populaires. Enjeu de débats autour des figures de l'exclu et de l'ouvrier au travail, la catégorie fonctionne à la fois comme ressource et contrainte dans les mondes de l'art. Parce que définir, critiquer, participer au cinéma social ne va pas de soi, parce que cette entreprise pose des questions de positionnement entre art et politique, l'analyse intègre discours et pratiques en jeu dans la réalisation des films sociaux. L'enquête de terrain a pris en considération la trajectoire des films étiquetés, de leur production à leur réception. Elle combine observations et entretiens auprès d'acteurs qui participent aux processus de fabrication et de qualification des œuvres: producteurs, réalisateurs, comédiens, techniciens, exploitants, critiques, chercheurs, militants et publics. On montre comment les formes de l'engagement autour des films sociaux prennent corps dans des dispositifs matériels (publications, manifestations cinématographiques) qui en assurent la diffusion, la circulation et la performativité entre différents espaces sociaux. Se donne ainsi à voir un espace de renouvellement de l'engagement des artistes et intellectuels de gauche dans un contexte de remise en cause de la légitimité de la politique et du militantisme partisanThis thesis deals with the social cinema label as it was defined in the second half of the 1990s and in the 2000s by cinema reviewers, researchers in social sciences and militants fighting against the effects of economic liberalism and globalisation. These actors of the mediation and the reception have gathered under this label French films dealing with the working class. Their debates, focussing on the figures of the marginal and of the worker, question the social cinema category, operating as a resource and a restraint into the art worlds. Because defining, criticizing and taking part in social cinema is not obvious, because this undertaking raises the question of the boundaries between art and politics, our analysis integrates the speeches and the practices involved in the making of social films. Indeed, the survey takes into consideration the trajectory of the labelled films, from their production to their reception. Our investigation combines observation and interviews with different people involved in the process of making and defining works of art: producers, directors, actors, technicians, cinema's managers, cinema reviewers, researchers in social sciences, militants and members of the audience. We highlight how the forms of commitment to social films are embodied in some material devices (press articles, books, cinematographic events) which ensure their diffusion, circulation and efficiency into different social fields. This reveals a renewal in the commitment of artists and intellectuals belonging to the Left in a context where the legitimacy of politics and party militantism is being called into question

Esta dissertação analisa dois documentários - "Generonautas, jornada por identidades mutantes" (Monika Treut, 1999) e "De gravata e unha vermelha" (Miriam Chnaiderman, 2014) - tendo o objetivo de discutir como a identidade de gênero e a sexualidade são expressas nessas obras. Balizam este estudo a concepção de identidade como em contínua transformação e, gênero, como construção histórica, cultural e política. Sustentam, especialmente, tal olhar, os estudos feministas e a teoria queer, que defende a superação da padronização binária heterossexual/homossexual. O trabalho avalia os diferentes pontos de vista dos documentários, considerando os momentos históricos de suas produções. No filme de Treut, destacamos o aspecto militante da obra ao abordar o cotidiano de uma comunidade de trasgêneros residentes em São Francisco (EUA), tendo a cidade um papel importante na causa em defesa dos corpos abjetos. Já no filme de Chnaiderman, buscamos entender como se apresenta a sexualidade e o gênero em sua multiplicidade, tendo a vestimenta como principal elemento de transgressão. Isto posto, enumeramos algumas indagações que atravessam esta pesquisa: como se constroem os diferentes ativismos nas duas produções, mantendo-se a perspectiva de uma militância desenhada pelas organizações LGBT (Lésbica, gay, bissexual e trans) e tendo em vista a construção e consolidação de direitos sociais para este grupo ao longo dos quinze anos, tempo de espaço entre as produções? Qual a articulação - seja em maior ou menor grau - com o cotidiano, no sentido de se reconhecer neste "espaço de vivência e convivência", uma trilha para a consolidação dos propósitos do ativismo? Quais as marcas temporais específicas dos filmes que dialogam com a teoria queer? Por fim, que questões éticas suscitam tais obras quando expõem indivíduos historicamente discriminados? Buscar responder a estas e outras questões próximas, significa, para esta pesquisa, apontar para a necessidade do rompimento da invisibilidade que ainda marca quem optou pela transexualidade e/ou outras formas de identidade sexual e de gênero e, ao mesmo tempo, reconhecer na mídia, mais especificamente no audiovisual de não-ficção, um locus potente e significativo no cenário da comunicação contemporânea
This dissertation analyses two documentaries - "Gendernauts, a march towards changing identities" (Monika Treut, 1999) and "Wearing necktie and red nail" (Miriam Chnaiderman, 2014) - within the scope of discussing how identity of gender and sexuality are uttered in these works. This study is delimited on a conception of identity as a continuing change as well as the gender as a historical, cultural and political construction. Such view is supported particularly by both the feminist studies and the queer theory which stands up for the overcoming of the binary heterosexual/homosexual standardization. The work considers the different points of view of the documentaries, taking into consideration historical moments of their production. In Treut´s movie we highlight the militant aspect of the work when dealing with everyday life of a community of transgenders who live in San Francisco (USA), having this city an important role in the cause that stands up for the abject bodies. However in Chnaiderman movie, we sought to understand how sexuality and gender present themselves in their multiplicity, showing attire as the main element of transgression. Therefore, we numbered some inquiries which go through this research: how these different activisms are built in the two productions, keeping the perspective of a militancy designed by the LGBT (Lesbian, gay, bisexual and transgender) organizations, having in vieview the construction and consolidation of social rights for this group over fifteen years, the gap between the two productions? Which articulation - be it to a greater or lesser degree - with everyday life, towards recognizing in this "space of experience and contact" a path for the consolidation of the purposes of the activism? What are the particular time marks of the movies that express the queer theory in dialogue? Eventually, what ethical issues raise such works when they expose individuals historically prejudiced? Seeking to answer to these and other close questions means for this research to lead to the need of breaking out the invisibility which still leaves marks on those who have opted for transsexualism and/or other forms of sexual and gender identity and, at the same time, recognize through the media, most particularly through the nonfiction audiovisual, a powerful and significant locus in the scenery of the contemporaneous communication

Previous issue date: 2015-02-25This thesis aimed to study the relationship that teachers in the municipal public school system establish with the cultural industry, meaning to understand the criteria by which these professionals attribute formative or pedagogical value to certain cultural products. The observation of the school environment suggests that teachers, in response to social expectations, tend to develop a sui generis relationship with culture, and also tend to make different distinctions between high culture and mass culture. It was this research's goal to study to what degree this distinction is present at the teaching activity, and how such distinction relates to the idea of an education that fosters criticism and autonomy. For this purpose, picking from the municipal public school system of São Paulo city, four schools were visited and six teachers interviewed. The theoretical reference of Critical Theory was adopted - mostly Horkheimer and Adorno reflections over the cultural industry (and its effects on conscience) and over pseudoformation - as were the concepts of desublimation repressive of art works and of artistic alienation, both present in Herbert Marcuse. It was also Marcuse who offered the chief theoretical background of total administration of post-industrial societies plus its consequences. The results obtained suggest that teachers indeed maintain a distinction between high culture and mass culture, but also that such distinction is actually complex and not necessarily linked to a greater ability by one teacher to promote criticism- and autonomy-oriented education. As an addition, it is noticeable how social pressure and pressure from the teaching institution's part weight more on the choosing of films, for teaching, than the teacher's personal relationship with cinema
Este trabalho visou estudar a relação que os professores da rede pública municipal estabelecem com a indústria cultural, buscando entender os critérios segundo os quais estes profissionais atribuem valor formativo ou pedagógico a certos produtos culturais. A observação do ambiente escolar sugere que os professores, em resposta a expectativas sociais, tendem a desenvolver uma relação sui generis com a cultura e a fazer distinções diferentes entre alta cultura e cultura de massas. Foi pretensão desta pesquisa foi estudar em que grau esta distinção está presente na atividade docente e como ela se relaciona com a ideia de uma educação que prime pela crítica e a autonomia. Para isso, foram visitadas quatro escolas e entrevistados seis professores da rede pública municipal de São Paulo. Foi adotado o referencial teórico da teoria crítica da sociedade, mormente as reflexões de Horkheimer e Adorno sobre a indústria cultural (e seus efeitos sobre a consciência) e pseudoformação, além dos conceitos de dessublimação repressiva da obra de arte e alienação artística, ambos presentes em Herbert Marcuse. Foi ainda Marcuse que ofereceu o pano de fundo teórico da administração total das sociedades pós-industriais e suas consequências. Os resultados obtidos sugerem que os professores de fato mantêm uma distinção entre alta cultura e cultura de massas, mas trata-se de uma diferenciação complexa, que não está necessariamente vinculada a uma maior capacidade do docente de efetivar um ensino voltado para a crítica e a autonomia. Em adição, é perceptível que as pressões sociais e da instituição escolar podem ter maior peso sobre as escolhas de filmes para ensinar do que a relação pessoal do professor com o cinema

Full textAbstract:
La succinate déshydrogénase (SDH) est à la fois une enzyme clé du cycle de Krebs oxydant le succinate en fumarate et le complexe II de la chaîne respiratoire mitochondriale impliqué dans le transfert des électrons et la réduction de l’ubiquinone. Des inhibiteurs de cette enzyme (SDHI) ont été développés ou sont en cours de développement comme antifongiques. Cette famille de fongicides est notamment utilisée pour lutter contre Botrytis cinerea, champignon phytopathogène responsable de la pourriture grise sur de nombreuses cultures dont la vigne. Des souches résistantes aux SDHI ont été isolées chez B. cinerea et d’autres champignons phytopathogènes. Chez ces isolats résistants, des mutations ont été identifiées dans les gènes codant la SDH. Au cours de cette thèse, nous avons étudié l’impact de mutations affectant la sous-unité B (SdhB) de la succinate déshydrogénase sur l’activité de l’enzyme, la biologie du champignon B. cinerea et la résistance aux inhibiteurs ciblant cette enzyme. Par mutagénèse dirigée du gène sdhB, nous avons obtenu des mutants dits « isogéniques » qui ont permis de confirmer l’implication de ces mutations dans la résistance aux différentes molécules SDHI. Par ailleurs, nos résultats montrent que les modifications de la sous-unité SdhB affectent l’affinité des SDHI pour la SDH et les niveaux d’inhibition de l’activité SDH par les molécules inhibitrices ; ce qui explique - in fine - les spectres de résistance des mutants aux SDHI. Actuellement, tous les mutants sont résistants au boscalid et les mutants les plus fréquemment retrouvés au vignoble, sdhBH272R/Y, sont sensibles au fluopyram. Les travaux réalisés sur les mutants sdhB montrent que les mutations étudiées ont également un impact sur l’activité de l’enzyme et sur le développement du champignon, conséquences dépendantes du résidu substitué et de la substitution. En particulier, les mutations sdhBH272L/R affectent fortement l’activité de l’enzyme et la fitness du champignon alors que le mutant sdhBH272Y est peu affecté. Enfin, l’analyse de populations de pourriture grise de différentes origines (région, plantes hôtes) par rapport à la résistance aux SDHI réalisée sur les années 2009/2010 montre que les mutants sdhBH272R/Y sont toujours les plus fréquents mais leurs fréquences varient en fonction des situations agronomiques. Notamment la fréquence du mutant sdhBH272R augmente avec la pression de sélection exercée par les fongicides. Ce mutant attire particulièrement notre attention du fait de sa relation non linéaire entre fitness et fréquence au champSuccinate dehydrogenase is both a key enzyme of the TCA cycle, oxidizing succinate into fumarate and complex II of the mitochondrial respiratory chain involved in electron transfer and ubiquinone reduction. Inhibitors of this enzyme (SDHIs) have been developed or are in the developmental process as fungicides. Actually, SDHIs are registered to deal with Botrytis cinerea, a phytopathogenic fungus responsible for grey mold on many crops including grapevine. Strains of B. cinerea and other pathogenic fungi have been isolated for their resistance to SDHI. They mainly harbor mutations in genes encoding SDH subunits. During this thesis, we studied the impact of mutations modifying subunit B of succinate dehydrogenase on enzyme activity, fungal biology and resistance to SDHIs. “Isogenic” mutants obtained through site-directed mutagenesis and homologous recombination allowed us to confirm the role of sdhB mutations in SDHIs resistance. Our results also show that the substitutions in the SdhB subunit impact respectively the affinity of SDHIs to SDH and the inhibition levels of SDH activity by inhibitors, which explain – in fine – the resistance spectra observed for the mutants. Up to now, all sdhB mutants are resistant to boscalid and the most frequent mutants observed in grapevines, sdhBH272R/Y, are susceptible to fluopyram. Studies on sdhB mutants reveal that the mutations also impact the enzymatic activity and the fungal development depending on the substitution. In particular, sdhBH272L/R mutations have the strongest impact on enzyme activity and the fitness of the fungus, whereas these parameters are almost not altered in the sdhBH272Y mutant. Finally, grey mold populations from different origins (country, plant host) were analyzed for their SDHI resistance pheno- and genotypes. Yet, the sdhBH272R/Y mutants were the most frequent, but these frequencies varied according to the agronomical situation. Interestingly, the frequencies of the sdhBH272R mutant seem to increase with the selective pressure exerted by fungicides. This mutant is of particular interest because of the absence of correlation between the fitness we measured and the frequencies we observed in natura

Full textAbstract:
The behaviour of individuals, communities and populations is one of the major determinants of their health outcomes. This thesis presents the findings from three research projects related to the need of health care systems to focus in health behaviour change related to physical activity (PA) to manage the current burden of chronic diseases.
This set of studies set out to investigate the adherence to the current PA recommendations in Catalan population, which appears to support low levels of inactivity in Catalan adults that add an avoidable burden to the nation’s Public Health system. This was undertaken because existing work in Spain – consistent with that in many other countries - has been based on isolated studies, conducted under different policies and through different economic circumstances. Three studies were conducted with the collective aim of exploring adherence to PA in the Catalan population and in Catalan physicians and to assess the outcomes of a primary care-based programme to promote health change related to PA in Catalonia. Collectively this work focuses on different and important facets of the challenge that underpins the promotion of behaviour change in adults The main findings of the studies were (i) high adherence to health-enhancing PA level based on walking activity by Catalan population but high prevalence of sedentary leisure time, (ii) poor lifestyle behaviours related to physical inactivity and overweight among Catalan physicians and (iii) the effectiveness of a PA referral scheme, promoted by the national program “Plan of Physical Activity, Sport and Health” (PAFES) on PA adherence, and associated improvements in quality of life of primary care patients with chronic conditions.
The PAFES program has powerful repercussions for changing health behaviour related to PA in Catalan adults and Catalan physicians. The increases in resources and service delivery improvements generated by PAFES was intended to positively impact on both primary health care providers and Catalan population, to overcome many of the established barriers seen regarding physicians’ barriers to PA counselling, resulting from two main factors; lack of protocols and having little relevant training. Furthermore, PA referral scheme has seen to be an effective and easily practicable method for increased PA and quality of life in routine primary care patients with chronic conditions. In addition, PARS promote increased PA in a wide part of the population who otherwise are hard to reach or have a low motivation for lifestyle changes.
In conclusion, adherence to PA in Catalan general population and in Catalan physicians’ population has been positively influenced by implementing the national Plan on Physical Activity, Sport and Health (PAFES) through primary care settings. The PAFES program provides a comprehensive strategy that can be deployed with relative ease for directly addressing the widespread clinical challenges that modern inactive lifestyles create for public health. This effectiveness is wide ranging and can be seen in changed health-related behaviours, which in turn reduce risk, morbidity and mortality.El comportament dels individus, les comunitats i les poblacions és un dels principals determinants de la salut. Actualment les malalties cròniques, concretament les cardiovasculars són la primera causa de morbiditat i mortalitat mundial. L’estil de vida és clau en l’adopció d’una salut cardiovascular òptima així com també en el control i millora de factors de risc cardiovasculars. L’adopció i l’adherència a l’activitat física (AF) és un determinant clau per la salut, que cal promocionar per gestionar la càrrega actual de malalties cròniques relacionades amb l’estil de vida així com també millorar la qualitat de vida. En aquesta tesi es presenten els resultats de tres projectes d'investigació relacionats amb la necessitat de promoure el canvi de conductes relacionades amb la salut. Aquest conjunt d'estudis té com objectiu inicial investigar l'adherència a les recomanacions actuals d'AF en la població catalana, resultat que repercuteix en la salut de la població. Aquest estudi es va dur a terme donat a que el treball existent a Espanya - en consonància amb el de molts altres països - s'ha basat en estudis aïllats, realitzats sota diferents polítiques i a través de diferents circumstàncies econòmiques. El segon estudi explora l’adherència a l’AF en una mostra de metges/esses catalans per explorar el nivell d’AF com el perfil òptim de metges/esses per promoure l’AF. El tercer estudi té com a objectiu l’avaluació d'un programa promogut pel "Pla d'Activitat Física, Esport i Salut" del programa nacional (PAFES), basat en l'atenció primària a Catalunya per promoure el canvi de conducta en relació a l’AF.

La finalidad del estudio fue valorar la eficacia de dos tipos de intervención (asesorado vs supervisado) en la conducta de actividad física y en la mejora de los factores de riesgo cardiovascular (FRCV) a corto y a largo plazo. Participaron 10 hombres y 12 mujeres, poco activos y con dos o más FRCV que se aleatorizaron en los dos grupos de estudio. La intervención de 6 meses de duración y 24 meses de seguimiento, comprendió 13 entrevistas individualizadas para la modificación de conducta (grupo asesorado) y 64 sesiones de ejercicio físico supervisado (grupo supervisado). Las principales variables desenlace fueron la conducta de actividad física, el índice de masa corporal, indicadores bioquímicos de riesgo cardiovascular, presión arterial e indicadores del estado cognitivo-conductual. Al finalizar la intervención, ambos grupos mejoraron su conducta de actividad física y los procesos de cambio y redujeron la presión arterial. La autoeficacia y el balance decisional obtuvieron mejoras solamente en el grupo asesorado. No se mostraron diferencias estadísticamente significativas entre grupos en ninguna de las variables analizadas. En el seguimiento solamente perduraron los cambios positivos en la conducta de actividad física y en los procesos de cambio.

Les principals variables desenllaç van ser la conducta d'activitat física, l'índex de massa corporal, indicadors bioquímics de risc cardiovascular, pressió arterial i indicadors de l'estat cognitiu-conductual. Al finalitzar la intervenció, tots dos grups van millorar la seva conducta d'activitat física i els processos de canvi i van reduir la pressió arterial. La autoeficàcia i el balanç decisional només van millorar en el grup assessorat. No es van observar diferències estadísticament significatives entre grups en cap de les variables analitzades. En el seguiment només van perdurar els canvis positius en la conducta d'activitat física i en els procesos de canvi. Tant les intervencions basades en l'assessorament i com les basades en la supervisió poden tenir els mateixos efectes en la conducta d'activitat física, en paràmetres clínics-bioquímics i cognitiu-conductuals.
The purpose of the study was to assess the effectiveness of two types of intervention (advised vs supervised) in the physical exercise behavior and improving cardiovascular risk factors in the short and long term. Twenty-two low active participants (10 men, 12 women) with two or more cardiovascular risk factors were randomized in two study groups. The 6-months intervention and 24-months follow-up included 13 individual behavior modification interviews (advised group) and 64 sessions of supervised physical exercise (supervised group). The main outcome variables were physical activity behavior, body mass index, biochemical indicators of cardiovascular risk, blood pressure and cognitive-behavioral state indicators. After the intervention, both groups improved their physical activity and behavior change processes and reduced blood pressure. Self-efficacy and decisional balance improvements were only observed in the advised group. No significant differences between groups in any of the variables were observed. At follow-up positive changes persisted only in physical activity behavior and processes of change. Interventions counseling-based and supervision-based may have similar effects on physical activity behavior, biochemical-clinical and cognitive behavioral parameters.

Full textAbstract:
Le présent travail, en analysant la trajectoire biographique du réalisateur japonais Sômai Shinji de son passage dans les mouvements de contestation de la Nouvelle gauche à ses premiers films tournés dans les années quatre-vingt, se veut une étude critique sur le sens généralement accordé à l’utilisation de la technique dite du « plan-séquence » dans le contexte du cinéma japonais. Le plan-séquence est une méthode de mise en scène que différents auteurs occidentaux, de Noël Burch à Donald Richie, ont régulièrement qualifié d’ « essentiellement » japonaise tant elle semble selon eux présenter une utilisation de l’espace qui la rapproche des arts de représentation traditionnels comme le théâtre kabuki ou la peinture de Heian. En mettant en évidence les fonctions de contestation et de résistance que cette technique joue dans l’esthétique des films de Sômai Shinji, activiste de la Quatrième internationale japonaise de 1967 à 1971, nous démontrons que le jugement selon lequel le plan-séquence découlerait d’une sensibilité propre au peuple japonais－en effet, d’une « japonité »－est pour le moins à revoir. Sômai, de par son passé politique, est un réalisateur qui est constamment en lutte avec les valeurs de ce que nous appelons l’ « idéologie dominante », si bien que sa trajectoire ne peut se comprendre qu’en tenant compte des notions de conflits et de contradictions, bien loin de l’image lisse et homogène du peuple japonais dont nous abreuve un certain discours. Au-delà de la relecture du sens accordé à l’usage de la technique du plan-séquence－à laquelle nous associons rapidement des cinéastes comme Mizoguchi Kenji ou Sone Chûsei－, cette thèse soulève donc certaines interrogations sur la perception que nous avons, à travers les médias audiovisuels, de la nation comme entité homogène et fixée dans le tempsThe present work, while examining the biographical trajectory of Japanese filmmaker Sômai Shinji from his past in the Japanese New Left to his first movies made in the 80s, is aimed at being a critical study of the significance regarding the use of the technique called “one scene-one shot” generally admitted in the context of Japanese cinema. The one scene-one shot is a method of mise-en-scène considered by several non-Japanese authors, like Noël Burch or Donald Richie, to be “essentially” Japanese because of what they think to be similarities with methods of representation usually found in kabuki theatre and Heian paintings. While we enhance the functions of protest and resistance this technique plays in the aesthetic of Sômai Shinji－who was an activist of the Japanese Fourth International from 1967 to 1971－films, we assess that the argument regarding the one scene-one shot as a method of filming particular to the Japanese sensibility－indeed, an expression of “Japaneseness”－is at best to be reconsidered. Sômai, because of his political past, was a filmmaker constantly struggling with the values of what we call the “dominant ideology”. His work cannot properly be understood unless we put the notions of conflicts and contradictions at the core of our analysis, departing from the traditionally peaceful and homogenous image that certain discourses usually express regarding the Japanese people. Beyond a reexamination of the significance traditionally given to the use of the one scene-one shot in the context of Japanese cinema－to which we associate filmmakers such as Mizoguchi Kenji and Sone Chûsei－, this dissertation questions the images of the nation, expressed through audiovisual means, as a homogenous and fixed community

Introducció: Els estudis indiquen que un percentatge molt elevat dels adolescents que viuen en països industrialitzats no assoleixen els mínims recomanats d’activitat física (AF) (Hallal et al., 2012). La pràctica esportiva no sempre és eficaç alhora de promoure altres estils de vida (Lisha & Sussman, 2010). Objectius: (i) Estudiar els nivells d’AF i pràctica esportiva entre els adolescents d’Osona. (ii) Trobar associacions entre nivells d’AF i altres estils de vida. Metodologia: Els adolescents nascuts l’any 1995 a Osona varen ser omplir un qüestionari el 2011 (n=695), el 2012 (n=668), el 2013 (n=411) i el 2014 (n=180). Resultats: (i) Els nivells d’AF durant el temps de lleure disminueixen en el pas de l’adolescència a l’edat adulta; (ii) associacions positives entre el consum d’alcohol i tabac i la pràctica esportiva entre els nois; i (iii) els adolescents d’Osona es passen > 700’ al dia asseguts. Discussió: És bàsic promoure la pràctica esportiva durant l’adolescència, però també la importància dels clubs esportius alhora de promoure l’adquisició d’estils de vida saludables.Introduction: Global studies reveal that a high percentage of adolescents are physically inactive (Hallal et al., 2012). Sports participation in adolescence is not always better at promoting healthy lifestyles than regular physical activity (PA). Aims: To observe the tracking of sport participation and PA among a group of adolescents from high school to university and to observe how this affects their lifestyle behaviours. Methods: Adolescents born in 1995 from Osona completed a questionnaire in 2011 (n=695), 2012 (n=668), 2013 (n=411) and 2014 (n=180). Results: Levels of PA at leisure time drastically reduced from late adolescence to early adulthood. The higher prevalence of alcohol consumption was in team sport players compared to other groups. Adolescents spend >700’ a day in a sitting position during weekdays. Discussion: Sport clubs (including coaches, venue and management team) have to put more effort to avoid the acquisition and maintenance of unhealthy habits (alcohol and tobacco consumption) among their athletes.

Full textAbstract:
Organic mulches and cover crops mulched in situ were assessed for their effects on B. cinerea primary inoculum and disease levels in inflorescences at flowering and/or bunches at harvest.
Organic mulches were used to enhance biological degradation of vine debris to reduce levels of B. cinerea primary inoculum the following season. Four mulch types (anaerobically and aerobically fermented marc (grape pressings), inter-row grass clippings and shredded office paper) were applied under ten-year-old Riesling vines in a ten-replicate randomized block design in New Zealand over two consecutive years. Plastic mesh bags, each containing naturally infected vine debris, were placed under vines on bare ground (control) and at the soil-mulch interface, in winter (July) 2003 and 2004. In each year, half the bags were recovered at flowering (December) and the remainder at leaf plucking (February), for assessment of B. cinerea sporulation from the vine debris and debris degradation rate. Bait lamina probes, which measure soil biological activity, were placed in the soil-mulch interface three weeks before each of the two bag-recovery dates in both years and were then removed and assessed at the same times as were the bags. All mulches led to a reduction in B. cinerea sporulation. This reduction was significantly correlated with elevated rates of vine debris decomposition and increased soil biological activity. Over both years, compared with the controls, all treatments gave a 3-20-fold reduction in B. cinerea sporulation, a 1.6-2.6-fold increase in vine debris degradation and in the two marc and the paper treatments, a 1.8-4-fold increase in activity of soil organisms.
The mulches also altered vine characteristics and elevated their resistance to B. cinerea through changes to the soil environment. Functional soil biological activity, as measured by Biolog Ecoplates and bait lamina probes, was increased 2-4 times in the two marc and paper treatments, compared with the control, an effect relating to the elevated soil moisture and reduced temperature fluctuations under these mulches. Soil nutrient levels and the C:N ratios were also affected in these treatments. The mulched paper lowered vine canopy density by up to 1.4 times that of the other treatments, an effect which probably led to elevated light penetration into the canopy and consequent increased canopy temperature, photosynthesis and lowered canopy humidity. These changes to soil and vine characteristics increased grape skin strength by up to 10% in the paper treatment and sugar concentrations by 1.2-1.4 °Brix in the two marc and paper treatments. The severity of B. cinerea infections in the anaerobic marc, aerobic marc and paper treatments were reduced to 12%, 3% and 2.2% of the control, respectively, in field assessments averaged over two consecutive harvests.
Cover crops mulched in situ had similar effects to those of the organic mulches, increasing soil biological activity and reducing B. cinerea primary inoculum and the severity of B. cinerea infection in grapes at harvest (2006). Inter-row phacelia and ryegrass were mulched in winter 2005 and compared with a bare ground control, under 10-year-old Chardonnay vines in a ten-replicate randomized block design. Functional soil biological activity increased by 1.5-4.5 times in the two cover crop treatments compared with the control, an effect possibly related to elevated soil moisture in these treatments. This increase in soil moisture and soil biological activity increased vine debris degradation, reduced B. cinerea primary inoculum on the debris and decreased B. cinerea severity at flowering (December 2005) and harvest (April 2006).
These results show the potential of organic mulches and cover crops mulched in situ to enhance soil ecosystem services and improve the sustainability of viticultural practices.

Full textAbstract:
Cette étude inédite se propose d’aborder un pan méconnu de l’histoire du cinéma dans l’enseignement. Le réseau « Freinet », du nom de son instigateur, Célestin Freinet, a joué, depuis la fin des années 1920, un rôle important dans l’introduction du cinéma à l’école en France. Il réunit, en marge du système traditionnel, des éducateurs militant pour des méthodes nouvelles d’apprentissage ; des « expérimentateurs » qui utilisent dans leur classe des outils originaux tel quele cinéma. Si le réseau « Freinet » existe toujours aujourd’hui, l’étude se borne aux expérimentations fondatrices (1927-1968). Ce flash-back historique vise à découvrir des usages hors du commun et d’une grande modernité. Les pratiques constituent le principal axe d’analyse pour déterminer un particularisme en matière d’emploi du cinéma en classe face aux formes d’utilisation usuelles qui consistent à employer le film comme support de la leçon. L’élève devient « acteur ». Cette acception de l’apprentissage ouvre la voie à de nouvelles formes d’exploitation de la projection. Elle ouvreaussi la voie au cinéma outil d’expression, de création et de développementThis unprecedented study addresses an unknown fold of Cinema History in education. The network « Freinet », named after its instigator Celestin Freinet, has played, since the end of the 20’s, an important role, by introducing the cinema into school in France. It brings together, outside the traditional system, educators campaining for new learning methods ; « experimenters » who use uncommon tools such as cinema in their class. Nowadays, if the network « Freinet » does still exist, the study is limited to the founders experimentations (1927 – 1968). This historical flashback aims to discover uncommon uses, also demonstrating a great modernity. Practices establish the main lead of the analysis in order to define a particularism in terms of uses of cinema in class, opposite common uses of movies as support of the lesson. The pupil becomes « actor ». This learning acceptance paves the way for new types of projection. It also opens the way for cinema as an expressing, creating and developing tool

Full textAbstract:
Depuis une vingtaine d’années, le milieu du documentaire chinois est en proie à des transformations radicales, qui se manifestent notamment par la production de films indépendants qui complètent et remettent en cause ceux qui sont diffusés dans les institutions officielles chinoises. Cette thèse vise en premier lieu à replacer les documentaires indépendants chinois dans la continuité des œuvres et des théories qui les ont générés, afin de comprendre leur sens et de définir leurs spécificités. La rupture qu’effectuent ces films dans l’histoire du cinéma chinois est en premier lieu conceptuelle : l’émergence de ces films dans les années 1990 traduit une tentative de redéfinition du documentaire. Emancipés des institutions officielles de production et de distribution du documentaire, ces films prennent une nouvelle fonction en circulant dans les espaces non-officiels qui incarnent la transformation structurelle amenée par les acteurs de ce mouvement. En instituant de nouvelles pratiques documentaires, ce mouvement effectue une rupture esthétique similaire à certains égards à celle que représente le cinéma direct dans l’histoire du cinéma occidental. Si les réalisateurs indépendants se servent de méthodes fondamentalement opposées à celles, didactiques et autoritaires, du documentaire officiel de propagande antérieur aux années 1980, ils assimilent dans le même temps les derniers développements de l’histoire mondiale de cette forme, et construisent une esthétique fondée sur l’enregistrement de l’expérience subjectiveSince the late 1980s, Chinese documentary films have been submitted to radical transformations, one of which is the emergence of independent productions which complement and question the official ones broadcast on Chinese televisions. The purpose of this dissertation is to evaluate Chinese independent documentary films on the background of the works and theories that helped generating them. These films testify firstly to a conceptual transformation in the history of Chinese cinema in the 1990s. Outside the official institutions for documentary film production and distribution, these films circulate in a non-official space and are appreciated in new structures that constitute the second major transformation brought by the actors of this independent movement. Finally, by using new documentary practices, this film movement presents a new documentary aesthetic, similar in certain aspects to the appearance of direct cinema in Western film history. The methods of independent filmmakers are fundamentally opposed to those of propaganda documentaries made before the 1980s, and they also assimilate the new developments of this film form to build a style based on the recording of subjective experience

Resumo: A cultura do morango é de grande importância no contexto agrícola mundial, com uma produção anual que supera 4,5 milhões de toneladas. Porém, as características desta fruta a tornam altamente susceptível a fatores físicos e biológicos de deterioração, tornando-a altamente perecível e acarretando altos níveis de perdas no campo e na pós-colheita. Dentre os fatores biológicos tem destaque a ação de fungos fitopatogênicos, dentre os quais o 'Botrytis cinerea' e o' Colletotrichum gloeosporioides' tem papel principal. Dentre as alternativas naturais para controle destes fitopatógenos, os óleos essenciais de plantas medicinais e aromáticas vêm sendo investigados. Neste contexto, no presente trabalho a atividade antifúngica de óleos essenciais de nove espécies de 'Citrus' e de 'Cymbopogon citratus' foi avaliada in vitro contra 'B. cinerea' e' C. gloeosporioides'. Os óleos de 'Citrus sinensis' e 'C. citratus' foram os mais ativos in vitro (MIC ¿ 0,25 e 0,06 mg.mL-1, respectivamente) e, portanto, selecionados para os ensaios com morangos in natura, visando manter sua qualidade pós-colheita. Os ensaios foram conduzidos sob duas condições ambientais, ou seja, sob condições ambiente de armazenamento (25 ºC) e em armazenamento refrigerado (10 ºC). Aplicados na concentração 1,0 mg.mL-1 , o óleo essencial de 'C. sinensis' mostrou-se mais eficaz sob condições ambiente de armazenamento, e a mistura dos dois óleos em partes iguais em armazenamento refrigerado. Em ambas as condições, melhores resultados foram obtidos através da aplicação por contato direto. Os óleos essenciais foram ainda incorporados a um filme de revestimento composto por matriz de metil-celulose e testados in vitro quanto ao seu potencial de inibição de 'B. cinerea'. Nestas condições, o óleo essencial de 'C. sinensis' mostrou-se o mais eficiente. Através dos resultados foi possível concluir que os óleos essenciais são uma opção viável para o controle de fitopatógenos em morango e para manutenção de sua qualidade pós-colheita
Abstract: The strawberry crop has great importance in agricultural world wide context, with an annual production exceeding 4.5 million tons. However, the characteristics of this fruit make it highly susceptible to physical and biological damage, making it easily perishable and causing losses in field and postharvest. Among the biological factors, the action of phytopathogenic fungi such as 'Botrytis cinerea' and "Colletotrichum gloeosporioides" have a main role. Natural alternatives have been proposed in order to replace synthetic products currently used in control of these plant pathogens, of which the essential oils from medicinal and aromatic plants have demonstrated good potential. In this context, the present study evaluated the in vitro antifungal activity of the essential oils from nine 'Citrus' species and from' Cymbopogon citratus' against 'B. cinerea' and 'C. gloeosporioides'. 'Citrus sinensi's and 'C. citratus' essential oils showed highest activities (MIC values 0.25 mg.mL-1 and 0.06 mg.mL-1, respectively) and were selected for the assays with in natura strawberries aiming at maintaining its postharvest quality. The tests were conducted under two simulated environmental conditions, ie, environment conditions of storage (25 ºC) and refrigerated storage (10 ºC). The crude essential oil of 'C. sinensis' (1.0 mg.mL-1) was the more effective in environmental conditions of storage, and the mixture of the two oils (1:1 ¿ 1.0 mg.mL-1) in refrigerated storage. In both conditions, best results were obtained when the oils were applied by direct contact. The essential oils were also incorporated into a coating film consisting of methyl cellulose matrix and tested to their 'in vitro' inhibitory potential against 'B. cinerea'. Accordingly, the essential oil of 'C. sinensis' proved to be the most effective as antifungal. The results allowed conclude that essential oils are a viable option for controlling phytopathogenic fungi in strawberry and for continuing postharvest quality

Orientador: Jorge Luís AkasakiResumo: Nos últimos anos, tem havido um crescente interesse em substituir parcialmente ou totalmente o uso do cimento Portland por materiais com baixo impacto ambiental; logo o estudo de aglomerantes ativados alcalinamente obtidos a partir da mistura de um precursor sólido, rico em aluminossilicato, e uma solução alcalina de alta concentração, tem se mostrado uma alternativa viável, uma vez que o consumo de energia e a emissão de CO2 durante a produção dessas matrizes são reduzidas, e ainda, ocorre a possibilidade de inserção de subprodutos agroindustriais, na matriz desses aglomerantes. Assim a presente tese apresenta um estudo de viabilidade do uso da cinza do bagaço de cana-de-açúcar (CBC), subproduto da indústria sucroalcooleira, na produção de aglomerantes ativados alcalinamente. A CBC foi obtida a partir da queima não controlada do bagaço de cana-de-açúcar e apresentou uma composição química predominantemente constituída de dióxido de silício. A cinza foi submetida a ensaios de caracterização física e química, de modo a avaliar a viabilidade do uso da cinza na produção de matrizes ativadas. Os ensaios de caracterização e de reatividade indicaram que a cinza apresenta grande parte da sua sílica no estado cristalino, além de apresentar baixa solubilidade e reatividade pozolânica. Porém, os ensaios térmicos e mecânicos das argamassas e pastas produzidas com a CBC, demostraram que, a CBC apresenta boa reatividade para períodos de cura prolongados, possibilitando o seu uso em matriz...

Abstract: In recent years, there has been a growing interest in partially or totally replacing the use of Portland cement with materials with low environmental impact; Therefore, the study of alkaline activated binders obtained from the mixture of an aluminosilicate rich solid precursor and a high concentration alkaline solution, proved to be a viable alternative since energy consumption and CO2 emission during production of these matrices are reduced, and also, there is the possibility of insertion of agroindustrial byproducts in the matrix of these binders. Thus, this thesis presents a viability study of the sugarcane bagasse ash (SCBA) use, a by-product of the sugar and alcohol industry, in the production of alkaline activated binders. The SCBA was obtained from the uncontrolled calcination of the sugarcane bagasse and presented a chemical composition predominantly constituted of silicon dioxide. The ash was physically and chemically characterized, in order to assess the viability of the ash use in the production of activated matrices. Characterization and reactivity analysis indicated that ash presents a great part of its silica in the crystalline state, low solubility and pozzolanic reactivity. However, the thermal and mechanical analysis of mortars and pastes produced with SCBA showed that ash presented good reactivity for long curing periods, allowing its use in Portland cement matrices and activated matrices. Two types of systems were analyzed in the activated matrices studies:... (Complete abstract click electronic access below)

O presente trabalho apresenta um método de produção de cinza de casca de arroz (CCA) altamente reativa e de coloração clara, bem como o seu comportamento em matrizes de cimento Portland com o intuito de avaliar a atividade pozolânica da CCA. O trabalho está dividido em quatro etapas, a saber: construção de um forno e produção da cinza de casca de arroz, caracterização físico-química da CCA, verificação da atividade pozolânica do material através de métodos instrumentais e, finalmente, ensaios mecânicos em argamassas de cimento Portland. O forno utilizado para a produção da cinza de casca de arroz não apresenta controle de temperatura e, o tempo de queima é bastante longo, aproximadamente 36 horas. Neste método obtém-se cerca de 1,5Kg de cinza por processo de queima. A cinza obtida apresenta uma coloração clara e o seu caráter amorfo foi determinado através de diferentes métodos: difração de Raio-X, determinação do teor de sílica amorfa, análise termogravimétrica, Microscopia Eletrônica de Varredura (MEV) e ensaios mecânicos em argamassas de cimento Portland. O programa experimental também abrange estudos de variação da finura da CCA e estudos com diferentes porcentagens, em substituição ao cimento Portland. Os resultados obtidos foram comparados...
This research show a method of production white amorphous Rice Husk Ash (RHA), therefore, the behaviour of RHA in Portland cement matrix to evaluate the pozzolanic activity of this material. The research can be shared in four steps, to know: construction of an oven and production of rice husk ash, physical-chemical analysis of the rice husk ash, evaluation of pozzolanic activity of the pozzolan though instrumental analysis and, finally, mechanical properties of Portland cement mortars. The oven used for production of rice husk ash didn't have a control of temperature and, the time of burning is so longer, approximately 36 hours. In this method is obtained for about 1,5Kg of ash. The obtained ash has white colour and its amorphous phase were determined though different methods: X-ray diffractometry, determination of amorphous silica, Termogravimetric Analysis (TA), scanning electron microscopy (SEM) and mechanical properties of Portland cement mortars. Besides that, the experimental procedure involves studies on fineness variation of rice husk ash and different degrees of Portland cement substitution. The obtained results were compared with silica fume, because this is the most similar pozzolanic material with rice husk ash. The RHA produced under this method can be used...

Proponiendo, al tiempo, contenidos críticos, independientes, contrainformativos y de denuncia. ¿Cómo nacen? ¿Cuál es su conexión con los referentes del pasado? ¿Cómo es su estructura organizativa? ¿Cómo entienden la cultura?¿Por qué hacen del cine su herramienta para la praxis política?¿Qué temáticas son las que producen o difunden?¿Cuál es su incidencia en el entorno en que se sitúan? Interrogantes todas que encontrarán respuesta en la aproximación a cada uno de ellos, revelando sus experiencias, dificultades, logros y contradicciones cotidianas, así como la manera en que han asumido la labor cinematográfica desde el empoderamiento colectivo, la intercooperación y la autoorganización.This investigation addresses the relationship between cinema and social activism. Particularly the way this two elements have been brought together nowadays in Barcelona-after the latest economic crisis and its resulting social protests. Several projects adopt different methods and agree to avoid as much as possible all commercial or institutional mechanisms when it comes to distributing or showing film material. They suggest critical, independent and denunciative content. How are they born? How they connect with past references? How are they organized? How they understand culture? Why they use cinema as a tool for politics? What topics are being produced and spread? How they affect their surroundings? All this questions will be answered reveling their experiences, difficulties, achievements, and daily contradictions, as well as the way they have assumed the cinematographic task from collective empowerment, inter cooperation and self-organization.

Resumo: O presente trabalho apresenta um método de produção de cinza de casca de arroz (CCA) altamente reativa e de coloração clara, bem como o seu comportamento em matrizes de cimento Portland com o intuito de avaliar a atividade pozolânica da CCA. O trabalho está dividido em quatro etapas, a saber: construção de um forno e produção da cinza de casca de arroz, caracterização físico-química da CCA, verificação da atividade pozolânica do material através de métodos instrumentais e, finalmente, ensaios mecânicos em argamassas de cimento Portland. O forno utilizado para a produção da cinza de casca de arroz não apresenta controle de temperatura e, o tempo de queima é bastante longo, aproximadamente 36 horas. Neste método obtém-se cerca de 1,5Kg de cinza por processo de queima. A cinza obtida apresenta uma coloração clara e o seu caráter amorfo foi determinado através de diferentes métodos: difração de Raio-X, determinação do teor de sílica amorfa, análise termogravimétrica, Microscopia Eletrônica de Varredura (MEV) e ensaios mecânicos em argamassas de cimento Portland. O programa experimental também abrange estudos de variação da finura da CCA e estudos com diferentes porcentagens, em substituição ao cimento Portland. Os resultados obtidos foram comparados...

Abstract: This research show a method of production white amorphous Rice Husk Ash (RHA), therefore, the behaviour of RHA in Portland cement matrix to evaluate the pozzolanic activity of this material. The research can be shared in four steps, to know: construction of an oven and production of rice husk ash, physical-chemical analysis of the rice husk ash, evaluation of pozzolanic activity of the pozzolan though instrumental analysis and, finally, mechanical properties of Portland cement mortars. The oven used for production of rice husk ash didn't have a control of temperature and, the time of burning is so longer, approximately 36 hours. In this method is obtained for about 1,5Kg of ash. The obtained ash has white colour and its amorphous phase were determined though different methods: X-ray diffractometry, determination of amorphous silica, Termogravimetric Analysis (TA), scanning electron microscopy (SEM) and mechanical properties of Portland cement mortars. Besides that, the experimental procedure involves studies on fineness variation of rice husk ash and different degrees of Portland cement substitution. The obtained results were compared with silica fume, because this is the most similar pozzolanic material with rice husk ash. The RHA produced under this method can be used...

A incorporação de resíduos diversos dentro de seus processos produtivos tem sido uma tendência na construção civil, esse processo visa a diminuição dos custos de produção e da deposição de resíduos no meio ambiente, dentro desta ótica as cinzas vegetais tem sido bastante estudadas devido as suas possíveis propriedades pozolânica. Para este estudo foi utilizada a cinza do bagaço da cana-de-açúcar (CBCA) proveniente do estado de Pernambuco, esse material foi submetido a um processo de secagem em estufa a 100°C e um peneiramento para retirar matérias contaminantes como folhas, madeiras e outros. O material foi dividido em quatro partes e submetido a um processo de calcinação nas temperaturas de 300°C, 400°C, 500°C e 600°C e chamadas de CB 300, CB 400, CB 500 e CB 600, a parte do material que não passou por esse tratamento foi denominada de CAN. Posteriormente a CBCA passou por um peneiramento em peneiras de malha #200 e #400 e a moagem em um moinho de bolas e por fim essas amostras foram submetidas aos ensaios de caracterizações físicas (Área específica, BET (BrunauerEmmett-Teller) e Massa específica) e caracterização química (D.R.X. e termogravimetria) e ensaios de consistência e resistência a compressão. A existência de atividade pozolânica foi testada através dos ensaios de D.R.X. e resistência a compressão segundo as normas da ABNT NBR 5751 (2012). No ensaios químicos (D.R.X.) ficou constatada a possível existência de atividade pozolânica do material estudado apenas nas cinzas moídas a sete horas, no ensaio de resistência a compressão apenas as cinzas moídas a sete horas apresentaram desempenho satisfatório. O estudo mostrou a importância do processo de moagem do material e de como o mesmo influencia na atividade pozolânica, já o processo de calcinação teve resultados abaixo do esperado principalmente nas temperaturas a partir de 500°C, já que as amostras apresentaram resultados melhores nas temperaturas de 300°C e 400°C.
The incorporation of various waste in their production processes has been a trend in the construction industry, this process is aimed at reducing production costs and waste disposal on the environment, within this perspective plant ash has been widely studied because of its potential pozzolanic properties. For this study we used sugar cane bagasse ashes (CBCA) from the state of Pernambuco, this material was subjected to a drying process in oven at 100 ° C and sieving to remove contaminating materials such as leaves, wood and others. The material was divided into four parts and subjected to a calcination process at temperatures of 300 ° C, 400 ° C, 500 ° C and 600 ° C and calls CB300, BC400, BC500 and BC600, the portion of the material which has not undergone this treatment was designated CAN. Subsequently the CBCA passed a sieve of sieve mesh # 200 and # 400 and grinding in a ball mill and finally the samples were subjected to physical characterization assays (specific surface area, BET (Brunauer-EmmettTeller) and Mass specific) and chemical (DRX and thermogravimetry) and consistency tests and compressive strength. The existence of pozzolanic activity was tested by the D.R.X. tests, thermogravimetry and compressive strength according to ABNT NBR 5751 (2012). In chemical assays (XRD and thermogravimetric analysis) was found to contain the reactivity of the material studied compared to pozzolan reference metakaolin (TCM), as compared to compressive strength testing only the ash grinded to seven hours (M7H) showed satisfactory performance. The study showed the importance of the process of grinding the material and how the same influence on the pozzolanic activity, since the calcination process results below mainly expected at temperatures from 500 ° C, since the samples showed better results in temperatures 300 ° C and 400 ° C.

Lo studio ricostruisce le fasi dell’attività missionaria di padre Alfonso Vagnone in Cina, che si svolse tra il 1605 e il 1640. Il lavoro è organizzato in tre parti, suddivise in cinque capitoli:
1. Formazione giovanile di Vagnone e successiva attività di insegnamento presso il Collegio Braidense di Milano. In seguito, il gesuita ottenne il permesso di recarsi in missione in Cina e giunse a Nanchino nel 1605, dove, dopo aver imparato con impegno e dedizione la lingua cinese, incominciò con successo la sua opera di evangelizzazione. Nel 1616 egli subì una dura persecuzione e fu espulso da Nanchino. Dopo cinque anni di insegnamento della filosofia e teologia nel Collegio S. Paolo a Macao, nel 1624 rientrò nella Cina continentale, riprendendo la sua attività di evangelizzazione a Jiangzhou. Morì il aprile 1640.
2. Attività missionaria di padre Vagnone a Jiangzhou. Con l’aiuto di Tommaso Han Lin e Pietro Duan Gun, egli fu il promotore della diffusione del cristianesimo nello Shanxi (tanto da essere considerato l’apostolo dell’evangelizzazione di questa provincia).
3. Studio delle opere del gesuita e, in particolare, del pensiero pedagogico ed etico espresso in un suo testo intitolato Educazione della Gioventù.
Il lavoro ha dunque cercato di mettere in luce gli aspetti più significativi della personalità scientifica, teologica, retorica, etica e missionaria di padre Alfonso Vagnone.The study reconstructs the stages of the Chinese missionary activity of Father Alfonso Vagnone, which took place between 1605 and 1640. The paper is organized into three parts, divided into five chapters: 1. Training of young Vagnone and subsequent teaching at the Braidense College of Milan. Later, the Jesuit was allowed to go on a mission in China and came to Nanjing in 1605, where, after learning the Chinese language with commitment and dedication, successfully began its work of evangelization. In 1616 he suffered a severe persecution and was expelled from Nanjing. After five years of teaching philosophy and theology at the College of St. Paul in Macao, he returned in mainland China in 1624, resuming his work of evangelization in Jiangzhou. He died on April 9, 1640. 2. Vagnone missionary activity in Jiangzhou. With the help of Thomas Han Duan Lin and Peter Gun, he was the promoter of the spread of Christianity in Shanxi (he is considered the apostle of the evangelization of this province). 3. Study of the works of the Jesuit and, in particular, the pedagogical and ethical thinking expressed in his text Education of Youth. Therefore, the work highlights the most significant aspects of Father Alfonso Vagnone scientific, theological, rhetoric, ethics, and missionary personality.

[EN] This research studies the activist audiovisual of social and political intervention field, deepening the emergence of video activism 2.0 in the XXI century. We refer to a number of alternative and political audiovisual works, of denunciation and resistance, leveraging the accessibility, ease, immediacy and versatility offered by current technologies (audiovisual, computers, telematics and communication) and new global digital scenarios of the web 2.0. Performances where the old and the new, the past and the present, clearly converge. For the purposes of accounting for our research objectives, we proceeded to conduct a descriptive study, organized in two stages. We did a systematization of research on various audiovisual productions of political intervention from the militant cinema, video activism of the eighties and nineties, to the audiovisual activism century and its interaction with the network. Here we identify goals, tactics and strategies to characterize and differentiate them according to their experimental, aesthetic, critical and political aspects. In a second step we conducted a case study with reference to the Catalan audiovisual collective: 15Mbcn.tv. This stage combined qualitative and quantitative (a methodological approach of mixed type) to understand the characteristics that the analyzed experience acquires. The study results allowed us to elucidate what is old in the new and what is new in the new, that is, specify the characteristics and specificities of current audiovisual works and their similarities and differences about their background. In that vein, the detailed analysis of the collective 15Mbcn.tv was a relevant contribution in order to make these reflections from the investigation of a particular contemporary paradigmatic case. On the other hand, we seek to understand the role of technological change in discursive, narrative, aesthetic and dissemination strategies of these practices of resistance, insistence and intervention in the video activism 2.0. Finally, and considering the results of the study, we share some thoughts around the limitations and potentials of these audiovisual practices as tools of aesthetic-critical-political intervention and as a tool of social and political transformation of consciousness in the particular context in which they develop.[ES] La presente investigación estudia el campo del audiovisual activista de intervención social y política, profundizando en el surgimiento del videoactivismo 2.0 en el siglo XXI. Nos referimos a una serie de prácticas audiovisuales alternativas, políticas, de denuncia y resistencia, que aprovechan la accesibilidad, facilidad, inmediatez y versatilidad que ofrecen las tecnologías actuales (audiovisuales, informáticas, telemáticas y comunicacionales) y los nuevos escenarios digitales globales de la web 2.0. Prácticas en donde lo viejo y lo nuevo, el pasado y el presente, claramente convergen. A los fines de dar cuenta de nuestros objetivos de investigación, se procedió a la realización de un estudio de tipo descriptivo, organizado en dos etapas. Una de sistematización de investigaciones en torno a diversas producciones audiovisuales de intervención política desde el cine militante, el videoactivismo de los años ochenta y noventa, hasta el activismo audiovisual del siglo XXI y su interacción con la red. En ella identificamos objetivos, tácticas y estrategias a fin de caracterizarlas y diferenciarlas de acuerdo a sus aspectos experimentales, estéticos, críticos y políticos. En una segunda etapa efectuamos un estudio de caso tomando como referencia al colectivo catalán 15Mbcn.tv. Dicha etapa combinó indagaciones cualitativas y cuantitativas (abordaje metodológico de tipo mixto) para la comprensión de las características que adquiere la experiencia analizada. Los resultados del estudio permitieron dilucidar qué hay de viejo en lo nuevo y qué hay de nuevo en lo nuevo, es decir, precisar las características y especificidades de los actuales trabajos audiovisuales y sus similitudes y diferencias respecto de sus antecedentes. En esa línea, el análisis puntual del colectivo 15Mbcn.tv constituyó un aporte de relevancia en aras de efectuar estas reflexiones a partir de la indagación de un caso concreto, paradigmático y contemporáneo. Por otro lado, se buscó entender el papel del cambio tecnológico en las estrategias discursivas, narrativas, estéticas y de difusión de estas prácticas de resistencia, insistencia e intervención del videoactivismo 2.0. Finalmente, y considerando los resultados del estudio, se comparten algunas reflexiones en torno a las limitaciones y potencialidades de estas prácticas audiovisuales como herramientas de intervención estética-crítica-política y de transformación de la consciencia social y política del contexto particular en el cual se desarrollan.

Full textAbstract:
This dissertation analyzes the narrative use of sound, the rhetorical appeal to be heard and the trope of listening in African American literature as well as Hollywood and international cinema. Contributing to the burgeoning fields of film sound and listening studies, Chapter One explores the relationship between the first experiments with synchronous sound recording technology and the construction of subjectivity along the lines of ethnicity, religion and gender in early talkies such as Al Jolson's The Jazz Singer and Alfred Hitchcock's Blackmail. Chapter Two surveys a range of abolitionist texts and select essays from the Civil Rights movement—particularly David Walker's Appeal to the Coloured Citizens of the World, Frederick Douglass's first autobiography Narrative of the Life and his novella "The Heroic Slave," W. E. B. Du Bois's The Souls of Black Folk and Richard Wright's White Man, Listen!–in order to review the role of listening across racial divides in the United States. Chapter Three analyzes the multiple ways in which listening functions for narrative purposes in Wright's best-selling novel, Native Son; and Chapter Four addresses the trouble with listening in Wright's posthumous novel A Father's Law and Hitchcock's first color film, Rope.
Contributing to film studies, gender studies, and critical race theory, this thesis argues that the act of listening comes to function figuratively as a trope, signifying not only a means of recognition, interpellation and subjugation of an Other but also an instrument of justice; a matter of politics; a means of education; a potential remedy for alienation, while at the same time working as a tool of oppression; a formative act in familial and other social relations; a governing form of surveillance; an audial gaze, so to speak; a way to frighten, or more generally, evoke emotion; a part of the therapeutic process; an indication of trust or confidence; a manifestation of (sexual) desire; and, last but certainly not least, an age old form of entertainment forever transformed by sound technology of the industrial age.

Previous issue date: 2014-01-31Cementing operation is one of the most important stages in the oil well drilling processes and has main function to form hydraulic seal between the various permeable zones traversed by the well. However, several problems may occur with the cement sheath, either during primary cementing or during the well production period. Cements low resistance can cause fissures in the cement sheath and compromise the mechanical integrity of the annular, resulting in contamination of groundwater and producing zones. Several researches show that biomass ash, in particular, those generated by the sugarcane industry have pozzolanic activity and can be added in the composition of the cementing slurries in diverse applications, providing improvements in mechanical properties, revenue and cement durability. Due to the importance of a low cost additive that increases the mechanical properties in a well cementing operations, this study aimed to potentiate the use of sugarcane bagasse ash as pozzolanic material, evaluate the mechanisms of action of this one on cement pastes properties and apply this material in systems slurries aimed to cementing a well with 800 m depth and geothermal gradient of 1.7 ?F/100 ft, as much primary cementing operations as squeeze. To do this, the ash beneficiation methods were realized through the processes of grinding, sifting and reburning (calcination) and then characterization by X-ray fluorescence, XRD, TG / DTG, specific surface area, particle size distribution by laser diffraction and mass specific. Moreover, the ash pozzolanic activity added to the cement at concentrations of 0%, 20% and 40% BWOC was evaluated by pozzolanic activity index with lime and with Portland cement. The evaluation of the pozzolanic activity by XRD, TG / DTG and compressive strength confirmed the ash reactivity and indicated that the addition of 20% in the composition of cement slurries produces improvement 34% in the mechanical properties of the slurry cured. Cement slurries properties evaluated by rheological measurements, fluid loss, free fluid, slurry sedimentation, thickening time and sonic strength (UCA) were satisfactory and showed the viability of using the sugarcane ash in cement slurries composition for well cementing
A opera??o de cimenta??o ? uma das etapas mais importantes no processo de perfura??o de po?os de petr?leo e tem a fun??o primordial de promover a veda??o hidr?ulica entre as diversas zonas perme?veis atravessadas pelo po?o. No entanto, v?rios problemas podem ocorrer com a bainha de cimento, seja durante a cimenta??o prim?ria ou no decorrer do per?odo produtivo do po?o. Cimentos de baixa resist?ncia podem causar trincas na bainha de cimento e comprometer a integridade mec?nica do anular, resultando em contamina??o de len??is fre?ticos e zonas produtoras. V?rias pesquisas comprovam que cinzas de biomassa, em particular, as geradas pela ind?stria sucroalcooleira apresentam atividade pozol?nica e podem ser adicionadas na composi??o das pastas cimentantes em diversas aplica??es, proporcionando benef?cios nas propriedades mec?nicas, no rendimento e na durabilidade do cimento. Dada a import?ncia de um aditivo de baixo custo e que aumenta as propriedades mec?nicas em uma opera??o de cimenta??o de po?os, este trabalho objetivou potencializar o uso da cinza de biomassa da cana-de-a??car (CBCC) como material pozol?nico, avaliar os mecanismos de atua??o desta nas propriedades de pastas de cimento e aplicar este material em sistemas de pastas destinadas ? cimenta??o de um po?o com 800 m de profundidade e gradiente geot?rmico de 1,7 ?F/100 p?s, tanto para as opera??es de cimenta??o prim?ria quanto corretiva (squeeze). Para isso, foram realizados m?todos de beneficiamento da cinza atrav?s dos processos de moagem, peneiramento e requeima (calcina??o) e, em seguida, a caracteriza??o por fluoresc?ncia de raios-X, DRX, TG/DTG, superf?cie espec?fica, granulometria a laser e massa espec?fica. Al?m disso, a atividade pozol?nica da cinza, adicionada ao cimento nas concentra??es de 0% (pasta padr?o), 20% e 40% BWOC, foi avaliada pelo ?ndice da atividade pozol?nica com a cal e com o cimento Portland. A avalia??o da atividade pozol?nica atrav?s das an?lises de DRX, TG/DTG e resist?ncia ? compress?o comprovaram a reatividade do material e indicaram que a adi??o de 20% de cinza na composi??o das pastas produz melhorias em at? 34% das propriedades mec?nicas da pasta endurecida. As propriedades das pastas avaliadas atrav?s dos ensaios de propriedades reol?gicas, perda de filtrado, ?gua livre, estabilidade, tempo de espessamento e resist?ncia ? compress?o (UCA) mostraram-se satisfat?rias e indicaram a viabilidade da utiliza??o da cinza na composi??o das pastas de cimento para po?os de petr?leo

Com o objetivo de reduzir a geração de resíduos nos processos industriais e agrícolas, bem como melhor reaproveitá-los, seja no próprio processo produtivo ou como matéria-prima na elaboração de outros materiais, tem-se cada vez mais investido em pesquisas para a transformação destes, até então considerados apenas resíduos industriais, em produtos de interesse comercial. Neste sentido, as cascas residuais oriundas do processo de beneficiamento de arroz vêm sendo utilizadas como combustível, visando ao aproveitamento energético. Mediante a queima da casca de arroz é gerada a cinza de casca de arroz composta basicamente de sílica, potencializando o uso deste resíduo em diferentes segmentos industriais. Muitos trabalhos aplicam a cinza de casca de arroz na construção civil, visto que grande parte dessas cinzas apresenta características pozolânicas decorrente da alta concentração de sílica amorfa presente no material. Pesquisas têm demonstrado que estas cinzas também apresentam potencialidade de aplicação como material adsorvente. No entanto, a cinza de casca de arroz apresenta-se, muitas vezes, como um material heterogêneo tanto na sua composição granulométrica quanto na sua composição química. Estas características podem interferir nas aplicações limitando seu aproveitamento. A segregação dos resíduos é uma técnica amplamente aplicada no gerenciamento de resíduos sólidos industriais e pode oportunizar a reciclagem dos materiais segregados. Neste contexto, este trabalho tem como proposta principal contribuir para a valorização do resíduo cinza de casca de arroz como co-produto através da etapa de segregação. Foi estudada a influência da segregação da cinza da casca de arroz nas características fisicoquímicas, bem como no seu desempenho como material pozolânico e adsorvente. As amostras e as frações segregadas foram caracterizadas através de parâmetros físicos (perda ao fogo, massa específica, área superficial, distribuição granulométrica) parâmetros químicos (análise química, difração de raio-X) e parâmetros microestruturais (microscopia eletrônica de varredura com espectro de dispersão de energia-EDS). A atividade pozolânica foi determinada após moagem das amostras e das frações através de ensaios de Pozolanicidade com o cimento e Condutividade Elétrica. Os ensaios de adsorção foram realizados com soluções de Cr(VI). O cromo residual foi quantificado pelo método colorimétrico da 1,5- difenilcarbazida. Resultados obtidos demonstraram que a segregação configura-se numa etapa importante, pois remove impurezas e contaminantes presentes na amostra, bem como origina frações diferentes, evidenciadas nos ensaios de caracterização. Nos ensaios de atividade pozolânica, observou-se que a influência da segregação relaciona-se com o tipo de processo de combustão aplicado para a obtenção da cinza. Nos ensaios de adsorção, observou-se que a segregação influenciou na remoção de cromo hexavalente. O estudo demonstrou, nas condições testadas, a viabilidade do uso de cinza de casca de arroz na adsorção do metal quando ajustados os parâmetros do processo que favoreçam a remoção dos íons de cromo.
The main objective for the industry is to reduce the generation of wastes, or to find better uses to them, such as in the own productive process or as raw material in the elaboration of other materials. Also, a great amount of funds has been invested in researches for the transformation of such wastes, in by-products of commercial interest. In this way, the rice husk from the rice processing have been used as combustible, for producing energy. Rice husk ashes are generated from the rice husk burning, which presents a potential to be used as raw material in the production of several products in different industry sectors. Most of the works apply the rice husk ash in civil construction, because a great part of those ashes present pozzolanic characteristics as a result of their amorphous chemical structure and the high silica content. In fact, between other factors, the pozzolanicity of rice husk ash depends on the thermal process applied to the rice husk during burning. Researches have been demonstrating that the ashes also may be potentiality applied as adsorbent. However, the rice husk ash comes, many times, as a heterogeneous material so much in your particle size distribution as in your chemical composition. These characteristics can interfere in the applications limiting your use. The segregation of the wastes is thoroughly a technique applied in the administration of industrial solid waste and it can guarantee the recycle of the segregated materials. This work has as main objective to contribute for the valorization of the waste rice husk ash as coproduct through the segregation stage. It was studied the influence of the segregation of the rice husk ash, in physical-chemical characteristics, as well as your acting as pozzolanic and adsorbent. The samples and segregated fractions were characterized via physical (fire loss, specific gravity, specific surface area, particle size distribution), chemical (chemical analysis, X Ray diffraction) and microstructural parameters (scanning electronic microscopy with energy dispersion spectroscopy – EDS). The pozzolanic activity was determined after grinding the samples and the fractions via Cement pozzolanic and Electric Conductivity Methods. The adsorption rehearsals were accomplished with Cr(VI) solutions, that was quantified by the colorimeter method using 1,5-difenilcarbazida. Results demonstrated that the segregation became an important step, because removes impurities and contaminants from the samples and also originates fractions with different characteristics. It was observed, in pozzolanic activity, that the influence of the segregation links with the type of applied combustion process for the obtaining of the ash. It was observed, in adsorption rehearsals, that the segregation influenced in the removal of chromium (VI). Adsorption results showed, considering the experimental conditions in this work, the viability of the use of rice husk ash in the adsorption of chromium (VI) when adjusted the process’s parameters that guarantee the removal of chromium.

Full textAbstract:
Sebbene la presenza dei figli degli migranti stia assumendo sempre maggior rilievo anche in Italia la ricerca ha posto poca attenzione alle loro scelte di consumo mediale e all’appropriazione dei media come risorse sociali ed ambientali. La tesi si focalizza sul caso delle giovani donne di origine araba per indagare il ruolo giocato dal consumo di notizie nella cornice più complessa dei processi di negoziazione di identità. Un focus è riservato alle tre dimensioni di appartenenze, partecipazione e trasmissione culturale tra generazioni – in relazione alle madri e ai coetanei. Un’indagine, a livello più “macro”, indaga le possibili implicazioni per il dialogo interculturale. Attraverso la raccolta di quarantotto storie di vita un primo livello di analisi diacronico indaga presenza e intensità del consumo di news nelle fasi della vita per comprendere se possa rappresentare un rito di passaggio all’età adulta, mentre una seconda pista cerca di comprendere come esso si leghi alla questione del sentirsi “cittadini”, in termini di riconoscimento, appartenenza e per scoprire se il consumo di news possa diventare una risorsa per essere soggetti attivi nella sfera pubblica. Tutte le giovani donne di origine araba vivono a Milano, hanno tra i diciotto e i trentadue anni e differiscono per le variabili di 1) nascita o arrivo in Italia dopo i 6 anni; 2) attivismo e 3) religiosità (musulmane, copte ortodosse, atee).Although the presence of migrants’ sons and daughters is gaining more and more importance also in Italy, the research have not given special attention to their choices concerning media consumption and to the appropriation of the media as social and environmental resources. This thesis is focused on the case of young women of Arab origin in order to investigate the intersections between news consumption and the negotiation of the social identity. A first focus is on three dimensions: participation, belonging and cultural transmission – in comparison with mothers and peers. A second “macro” level of the research investigates the implications as regard to intercultural dialogue. Through the collection of forty-eight life histories, a first level of diachronic analysis investigates the presence and the intensity of news consumption in different stages in order to understand if it could be a rite of passage to the adulthood, while a second track tries to understand how this is connected to the feeling of being “citizens”, in terms of identification, belonging and to investigate if news consumption may be a resource to be active citizens in the public sphere. All young women of Arab origin live in Milan, they are between eighteen and thirty-two years old, and differ in variables 1) they were born or arrived in Italy since they were 6 years old, 2) activism and 3) religion (Muslims, Coptic Orthodox or atheists).

This thesis explores the various meanings and implications of transparency in architecture and in learning environments in particular. Architectural transparency, achieved through choice of materials and principles of formal composition, creates a diversity of relationships and can facilitate visual, conceptual, and functional clarity as well as offering simultaneous perception of different spaces. It offers a range of phenomenological qualities and so provides an opportunity to explore and complicate such dichotomies as translucency and opacity, openness and closure, and public space and private space.
While celebrated throughout modern and contemporary architecture, transparency raises issues of privacy and safety even as it breaks down hierarchies and social boundaries. The research-based design of transparency in a school building necessitates careful planning to achieve a balance between the access to views, natural light, fresh air, and social interaction that transparency may bring and the continuing obligation to provide a safe, secure environment for schoolchildren.

La pratique documentaire trouve de nouveaux canaux au-delà de l’écran de cinéma. Grâce à ces différents moyens, le documentaire ouvre des espaces en ligne et hors ligne pour la construction de sens à travers des collaborateurs, y compris l’auditoire.
Le projet documentaire transmédia Who is Dayani Cristal ? a été choisi pour comprendre les ressources d’un projet s’intéressant à l’activisme, et plus précisément, dans ce cas-ci, aux problématiques migratoires. Dans le cadre de cette recherche, ce projet sera analysé en tant qu’i-Doc à travers une méthodologie multimodale, ce qui favorisera le discernement en lien avec la construction de sens par les créateurs du projet ainsi que par les collaborateurs qui y participent. Cette co-construction de sens mobilise des valeurs qui rassemblent des participants qui ne sont pas nécessairement dans le même contexte géographique, mais qui deviennent une communauté dans le cadre de la collaboration polyphonique de ce documentaire transmédial.
À travers des significations modales et leurs fonctionnalités dans l’ensemble d’un projet interactif non fictionnel à des fins politiques, les espaces ouverts à la co-création de sens offrent les circonstances pour engager les publics vers le changement social. Ainsi, le documentaire transmédia et sa nature interactive peuvent favoriser la rencontre de participants qui prennent conscience de la nécessité d’agir et se mobiliser par un mimétisme politique.Documentary practice finds new media beyond the cinema screen. Through these different channels, the documentary opens online and offline spaces for the construction of meaning through collaborators, the audience included. The transmedia documentary project Who is Dayani Cristal? was chosen to understand the resources of a project aimed at activism, in this case on migration issues. Within the framework of this research, this project will be analysed as an i-Doc through a multimodal methodology which make possible the discernment about the construction of meaning by the creators of the project as well as by the collaborators who participate in it. This co-construction of meaning mobilizes values that bring together participants who are not necessarily in the same geographical context, but they become a community within the framework of the polyphonic collaboration of this transmedial documentary. Through modal meanings and their functionalities throughout a non-fictional interactive project for political purposes, open spaces encourage co-creation of meaning providing the circumstances for audiences to engage in social change. Thus, the transmedia documentary and its interactive nature can motivate the meeting of participants who become aware of the need to act and mobilize themselves through a kind of political mimesis.

La version intégrale de la thèse a été déposée à la Division de la gestion des documents et des archives.La prévisualisation cinématographique, c’est-à-dire la mise en forme visuelle du scénario visant à préciser le film à venir, constitue une pratique dont les origines remontent aux débuts du cinéma. À travers le prisme ludique, notre thèse propose que la récente transition des outils traditionnels de prévisualisation vers des dispositifs numériques apparentés aux technologies vidéoludiques transforme cette préparation visuelle en l’apparentant sur plusieurs points à un jeu, voire à un jouet. Nos recherches portent sur la démarche créative du réalisateur, et comment l’exercice de son imagination mène à la fabrication d’un simulacre du film par le biais d’une dynamique itérative et de différents supports propres à représenter l’œuvre envisagée. Cette démarche est étudiée principalement dans le cadre de longs métrages impliquant une part substantielle d’effets visuels, un corpus particulièrement susceptible d’impliquer des stratégies élaborées de préparation logistique ou créative. À la suite d’un résumé historique impliquant une typologie des formes de prévisualisation et l’identification de variables propices à orienter les analyses subséquentes, notre thèse présente les notions d’imagination et d’attitude ludique, et précise comment ces ancrages théoriques sont utilisés pour mieux définir les aspects de la conception du film qui s’apparente au jeu. Par la suite, et au moyen d’une étude de cas impliquant un jeu vidéo remédié en un outil de machinima, elle détaille l’élaboration de la double figure dite « jeu de construction/jouet à construire » propre à représenter la nature et la dynamique de la prévisualisation selon un point de vue ludique. Nos recherches examinent ensuite les différents contextes de la production cinématographique quant à leur pertinence à l’exercice de la préparation visuelle par le réalisateur, tout en déterminant les aspects de la fabrication du film qui échappent à une telle mise en forme, lorsque réalisée au moyen des dispositifs conventionnels. À la lumière de cet examen, notre thèse propose l’émergence d’un nouvel espace de jeu, déployé transversalement à la chaine de production traditionnelle, et susceptible de favoriser la pratique d’une prévisualisation d’inspiration ludique qui répond de manière satisfaisante aux principales lacunes préalablement relevées.
Film previsualization (or previs), that is to say the visual formatting of the scenario aimed at anticipating the film to come, constitutes a practice whose origins date back to early cinema. According to a lusory perspective, our thesis proposes that the recent transition from traditional previs tools to digital devices involving videogame technologies transforms visual preparation by making it more similar to a game, or eventually to a toy. Our thesis focuses on the creative approach of the director, more specifically the process of imagination and how it leads to the design of a simulacrum of the film through an iterative method while using a variety of media fit to represent the intended work. This approach takes place mainly in the context of feature films involving a substantial part of visual effects, a corpus particularly likely to involve elaborate strategies relating to logistical or creative preparation. Following a historical background, a typology of the main forms of previsualization and the identification of variables suited to guide subsequent analysis, both notions of imagination and lusory attitude are studied in order to better define the aspects of film creation that relate to play and game. Afterwards, our thesis details the twin figure of the “construction game” and the “toy to build” representing the nature and dynamics of previsualization from a lusory perspective. This will be achieved by means of a case study involving a videogame remedied as a machinima tool. Our thesis then examines the different contexts of film production as to their relevance to previsualization practices performed by the director, while exposing the aspects of filmmaking that elude such practices when carried out by means of traditional devices. In the light of this examination, our thesis suggests the emergence of a new context of play, deployed transversally to the traditional production chain, and likely to favor the practice of a lusory-inspired previsualization that addresses in a successful way some of the shortcomings previously listed.

Au cours de l'Histoire, les humains alors nomades sont devenus sédentaires. Est-il
possible de tisser des liens entre les différentes formes de nomadisme actuel et une
certaine implication politique ? Selon une approche critique des pouvoirs
hégémoniques, l'auteur répond à cette question à travers une expérience
cinématographique nomade dans le Nord-ouest argentin. Il étudie les relations qui
peuvent exister entre une pensée nomade, le militantisme et le cinéma. Suivant les
révolutions sociales des années 30 à 70, certains nomades, qui parcouraient le
monde comme contestation d'un mode de vie normatif, se tournent aujourd'hui vers
un existentialisme quotidien. Quant au cinéma militant argentin, sa pratique passe
d'une confrontation révolutionnaire face à l'hégémonie, vers la construction de
subjectivités variées et précises. L'agencement entre le cinéma militant et
l'expérience nomade mettra à jour l'importance d'une « communication nomade »
qui s'installe aux interstices de la contestation sociale et de l'autonomie
individuelle.Throughout history, humans have gone from a nomadic to a sedentary lifestyle. Is it possible to forge links between current forms of nomadism and political involvement? Using a critical approach of the powers of dominating institutions, the author answers this question through a nomadic cinematic experience in Northwestern Argentina. The film studies the relationships that exist between nomadic thought, activism and film. After the social revolutions of the 1930's through the 1970's, nomads who had once challenged conventional lifestyles are IV today turning towards existentialism. Meanwhile, the practice of militant cinema in Argentina has changed from a revolutionary confrontation against hegemony, towards the construction of subjective identities. The link between militant cinema and the nomadic experience brings to light the importance of "nomadic communication" between social protest and individual autonomy.
Durante la historia, los seres humanos pasaron de ser nómadas a sedentarios. ¿Es posible establecer vínculos entre las diferentes formas de nomadismo actual y una cierta implicación política? Según un enfoque crítico de los poderes hegemónicos, el autor responde a esa pregunta a través de una experiencia de cine nómade en el noroeste argentino y estudia las relaciones que existen entre el pensamiento nómada, el activismo y el cine. Siguiendo las revoluciones sociales de los años 30 a los 70, algunos nómadas que vagaban por el mundo como desafío a un estilo de vida normativo, hoy están recurriendo a un existencialismo diario. En cuanto al cine militante argentino, su practica pasa de una confrontación revolucionaria contra la hegemonía, a la construcción de subjetividades variadas y precisas. El agenciamiento entre el cine militante y la experiencia nómada actualizará la importancia de una "comunicación nómada" que se instala en los intersticios de la protesta social y la autonomía individual.
