The purpose of this qualitative study was to explore the association between student involvement and self-authorship among African American undergraduate students enrolled at a medium-sized, North Texas STEM-focused university. Self-identified African American undergraduate students at the university completed an online, researcher-developed survey focused on co-curricular involvement activities, degree of involvement in those activities, and perceived self-authorship indicators. From the completed survey pool (N = 49), 10 females and 5 males participated in follow-up focus group sessions. The survey data analysis was limited to descriptive statistics of student involvement and demographic data. Survey results showed that African American undergraduate students at the university were actively involved in co-curricular activities and generally satisfied with their involvement experiences. The focus groups provided a more in-depth picture of the involvement experiences showing that students believed that their commitment to co-curricular activities contributed significantly to their interpersonal and intrapersonal growth—characteristics of self-authorship. The survey and qualitative data combined suggested a positive association between the involvement of African American undergraduate students in co-curricular activities at the university and the development of self-authorship characteristics in those students. Findings from this study support the practice of intentional outreach to African American undergraduate students in order to promote their active involvement in campus activities and events.

“Between Floors: The Ups and Downs of Mediated Narrative” and the accompanying creative remediation project, “Between Floors: Love and Other Blood Related Diseases,” meld theory and practice of print with electronic literature and installation art. I argue that as the medium changes, the narrative is transformed. The narrative can be reconstructed and pieced together as the reader or viewer becomes increasingly involved, even embodied within the work. This embodiment is what Nathaniel Stern calls “Moving and thinking and feeling” (1) and can result in a more direct emotional experience. The form, structure, and medium (sjužet) rely on authorial intention, yet as a narrative becomes more interactive and experiential the feedback loop shifts, placing meaning, message, and construction of narrative (fabula) between media and reader/viewer. This necessarily complicates the notion of authorship, yet within an embodied space, such as the installations included in this analysis, there is a potential for greater emotional understanding between author/artist and reader/viewer. In the print story “Between Floors: Love and Other Blood Related Diseases,” the protagonist, June, visits her father in a hospital after a tragedy and ends up spending the rest of her life there. The metaphor of an elevator throughout the print, electronic, and installation versions furthers the trapped, claustrophobic feeling of the narrative as well as the ups and downs of relationships and grief. Pieces of the narrative remain recognizable through the electronic literature and installation, yet as the reader/viewer is increasingly immersed in the narrative, it becomes his or her own—a more subjective and overwhelming emotional experience. The elevator metaphor extends through the analysis—an emblem of traditional linear narratives and the narrative arc and technological immersion. The analysis explores theories of language, medium, authorship, nonlinearity, interactivity, and embodiment through existing narrative, new media, and installation theorists such as Peter Brooks, Marshall McLuhan, and Nathaniel Stern. This dissertation and to an extent, experiment, uses theory and practice to illuminate narrative using a recombination of existing theory and an original remediation in three distinct forms, to further the understanding of the nature of narratives, media, authors, and readers, while blurring boundaries between disciplines.

Qui fait quoi au sein d’une équipe de recherche scientifique? Ce mémoire propose de définir les rôles de chacun des auteurs à l’aide d’une méthodologie originale. L’ordre des auteurs est un indicateur utile de l’importance relative de chacun des co-auteurs, mais il ne révèle pas la nature précise de leur rôle au sein de l’équipe. Ainsi, notre recherche démontre que l’utilisation des libellés de contributions aux articles scientifiques à des fins bibliométriques est possible et ce, même à grande échelle. Nos résultats montrent qu’il existe des différences dans les contributions apportées aux articles scientifiques et que ces différences s’appliquent aussi à la répartition du travail au sein des équipes de recherche selon le sexe des auteurs. / Who does what in a scientific research team? This work proposes to define the roles of each author with an original methodology. The order of the authors is a useful indicator of the relative importance of each of the co-authors, but it does not reveal the precise nature of their respective role. Our research shows that using statements of contributions from scientific articles for bibliometric purposes is possible, even on a large scale. Our results show that there are differences in the contributions to scientific articles and these differences also apply to the distribution of work among research teams by gender.

La prose et la poésie de Wolfgang Hilbig mobilisent un grand nombre de topoï, clichés et scénarios de l’existence poétique et de lavocation artistique, qui revêtent à la fois une fonction légitimante et critique. Ils répondent à l’improbable vocation de cet autodidacte est-allemand d’origine prolétaire. Les figures de poètes ou d’écrivains sont les supports d’une poétologie auctoriale héritière du romantisme et de la modernité, incarnée en particulier par la figure paradoxale de Kaspar Hauser. Interprétée comme une construction littéraire, fantasmatique et mythique située en aval de l’oeuvre, l’auctorialité est ici une théorie de la littérature incarnée dans des personnages et des modèles figuratifs de vies vouées à l’art. Les figures de la rupture d’équilibre, le motif de la lettre et le dispositif narratologique de la métalepse d’auteur se lisent comme des mises en scène de la condition poétique, de la relationtexte/auteur et de la transformation de l’auteur en fiction, sur lesquelles repose le projet existentiel de littérarisation de soi qui fonde l’écriture de Hilbig. Enfin, les textes esquissent des scénarios de vie faisant pièce au modèle de la prédestination. Ils explorent des possibilités de figurer la vocation improbable à travers les formes du cercle, de l’explosion, du saut et de l’événement, opposées au schéma linéaire de la prédestination, qui a partie liée avec la temporalité. Face à cette biographie extérieure, à cette vie exotérique, l’oeuvre de Hilbig piste les mouvements de la vie ésotérique, secrète, illisible et sans nom dans laquelle se joue la vocation désormais comprise comme promesse d’éternité. / Wolfgang Hilbig’s prose and poetry bring into play a large number of topoï, clichés and scenarios of the poetical life and of theartistic calling, both in a critical and in a legitimating way. They function as a response to the unlikely vocation as a writer of a selftaught,East German proletarian. In Hilbig’s work, poet or writer characters convey an authorial poetology that appear as a legacy of Romanticism and Modernity, which the paradoxical figure of Kaspar Hauser particularly stands for. Interpreted as a literary, phantasmatic and mythical construct resulting from the work itself, authorship consists here in a theory of literature embodied by models of art-dedicated lives. The figures of the loss of balance, the motif of the letter and the narratological device of the authorial metalepsis are read as means of staging the situation of the poet, the text/author relationship and the fictionalization of the author.Those are the bases of Hilbig’s existential project of self-literarization. Finally, Hilbig’s texts sketch life scenarios that thwart the predestination model, exploring the unlikely vocation through figures such as the circle, the explosion, the jump and the event, all of which go against the linear model of redestination that rely on temporality. As an alternative to this outward biography, this exoteric life, Hilbig’s work tracks the movements of a secret, unreadable and nameless esoteric life where vocation develops as a promise of eternity. The question of authorship in Hilbig’s work cannot be separated from a meditation on time and an idealistic perception of the world.

Esta tese analisa as personagens femininas da autora portuguesa Júlia Nery, presentes tanto nas narrativas ficcionais, quanto nos romances históricos, discutindo algumas questões pertinentes aos estudos de gênero, à crítica literária feminista e ao novo romance histórico. Desta forma, verifica em que medida se faz a reconstrução ficcional e, consequentemente, a representação destas personagens, tendo em vista os modelos femininos histórico e socialmente criados. Ao trabalhar com a hipótese de que a autora faz uma (re)leitura sobretudo transgressora e crítica da tradição e da História, construindo personagens que ficcionalmente rompem com os paradigmas que secularmente foram impostos ao gênero feminino, ao fim, procura evidenciar e sugerir à crítica literária mais atual, que a produção literária de Júlia Nery caracteriza-se como uma importante contribuição a uma vertente da Literatura Portuguesa, formada pelas vozes e pelos olhares das mulheres escritoras, que conjuntamente vem formando em Portugal uma nova tradição: a literatura de autoria feminina, de veio notadamente feminista. / This thesis analyzes the female characters by Júlia Nery, a Portuguese author. They are extant as in fictional narrative as in historical romance, where we argue about some issues belonging to gender studies, to female literary criticism and to new historical romance. Thus, we verify in what way are done the fictional reconstruction and, consequently, the representation of these characters, by aiming the female historical and social originated models. Our hypothesis is that the author does, markedly, a trespassed and critical (re)reading of the tradition and History. This reading is done with characters that break paradigms, which were imposed to the female gender, secularly. Also, this thesis seeks to evidence and to suggest to the recent literary criticism that, the literary production, by Júlia Nery, is marked with an important contribution to one slope of the Portuguese Literature, whose slope is formed by the voices and glances of female writers. Altogether, they are forming a new tradition in Portugal: the female authorship literature whose spindle is, notedly, feminist.

As redes de comunicação têm impulsionado um significativo deslocamento nos processos autorais de escrita, que adquirem nova dinâmica no meio digital, apresentando-se cada vez mais como uma ação interativa entre diferentes agentes criadores. Com base no pensamento de Michel Foucault sobre o tema da autoria, esta tese explora o significado desse deslizamento da posição do autor, ou da função-autor como propõe o filósofo, estruturada atualmente em uma rede de interações. A fim de construir uma reflexão sobre esse fenômeno, parte-se da pesquisa sobre a historicidade do conceito de autoria, buscando explorar as diversas constituições das práticas sociais da produção textual através da história, desde a Antiguidade até o momento atual das redes eletrônicas. Neste percurso, a Modernidade é reconhecida como o período específico no qual o processo autoral adquire uma configuração mais centrada no indivíduo, época em que também ganha espaço a noção de obra fechada e proprietária. Compreendendo a constituição da história como um processo complexo no qual se correlacionam diversas dimensões de acontecimentos, alguns aspectos que se articulam com esta questão são aprofundados na forma de intertextos. Deste modo, são abordados em diferentes capítulos os seguintes temas: as especificidades da linguagem do meio digital e suas implicações para a questão autoral; as transformações nas formas de criação e circulação dos bens intelectuais trazidas pelo advento do capitalismo cognitivo; as novas formas de validação da produção textual discursiva em publicações eletrônicas que estão sendo criadas como alternativas ao modelo editorial centralizado típico do meio impresso. Por último, com o objetivo de trazer elementos empíricos para a pesquisa, foram realizados estudos de observação participante e de observação nos sites Wikipédia e Overmundo, e também desenvolvidos um blog e um experimento wiki especialmente para a pesquisa. Com base nestes estudos, foi proposta uma tipologia da autoria interativa em rede, a saber: a colaborativa, quando o processo autoral se dá através do trabalho de duas ou mais pessoas que interagem na elaboração de um texto de forma cooperativa; e a dialógica, quando pode ser observada a interação dialógica entre um texto principal e intervenções na forma de comentários, compondo ao final um todo discursivo. Assim, através da articulação de diferentes reflexões teóricas com a pesquisa empírica, buscou-se compor um estudo abrangente do atual fenômeno da autoria interativa nas redes de comunicação. / Communication networks have driven a significant displacement in the authorship processes of writing, which acquire a new dynamic in the digital media, presenting themselves more and more like an interactive action between different creation agents. Based on the thought of Michel Foucault on the subject of authorship, this thesis explores the meaning of the sliding position of the author or author-function as the philosopher proposes, currently structured in a network of interactions. In order to build a reflection on this phenomenon, we start from the research on the historicity of the concept of authorship, trying to explore the various constitutions of the social practices of text production through history, from Antiquity to the present electronic networks times. In this route, Modernity is recognized as the specific period in which the authoring process acquires a more individual-centered setting, time when the notion of closed and proprietary work gains space. Taking the formation of history as a complex process in which correlate several dimensions of events, some aspects that articulate to this question are detailed in the form of intertexts. Thus, in different chapters are discussed the following themes: the specificities of digital media language and its implications for the authorship issue; the changes in the forms of creation and circulation of intellectual goods brought about by the advent of cognitive capitalism; new forms of discursive textual production validation in electronic publications that are being created as alternatives to centralized publishing model typical of print medium. Finally, in order to bring empirical elements for the research, were conducted sites participant observation studies and observational ones on Wikipedia and Overmundo, and also developed a blog and a wiki experiment specially for the research. Grounded on these studies, a typology of interactive authoring network was proposed, namely the collaborative one, when the authorship process is done throughout the work of two or more people interacting in the preparation of a text in a cooperative way, and the dialogic one, when a dialogic interaction between the main text and interventions in the form of comments, making the end a whole discourse, can be observed. Thus, through the articulation of different theoretical reflections with empirical research, we tried to make a comprehensive study of the broad phenomenon of interactive authoring in communication networks

As tendências de ensino de língua portuguesa concernentes à Educação Básica no Brasil privilegiam abordagens linguísticas e discursivas centradas na produção, circulação e recepção de textos. Decorrente dessa tendência, a tese investiga noções de estilo de gênero e de autoria a partir da Olimpíada de Língua Portuguesa Escrevendo o Futuro (OLPEF, 2008). A OLPEF é um dos programas de políticas públicas de incentivo à leitura e à produção escrita desenvolvido por meio de sequências didáticas para o trabalho com texto. O corpus da pesquisa é constituído do Caderno do Professor Se bem me lembro... (2008) e de um conjunto de textos finalistas da OLPEF, relativos à coletânea Memórias (2008). A temática desse corpus, portanto, é memorialista. Em termos teóricos, a tese tem como base os fundamentos da filosofia bakhtiniana de linguagem em correlação com desdobramentos da semiótica discursiva francesa a fim de desvendar questões que norteiam o estilo em enunciados memorialistas, tal como produzidos pelos alunos participantes do evento, do que emerge a questão de autoria, pertinente à produção escrita desse aluno no contexto da OLPEF. Para isso, a tese apresenta análises e reflexões a respeito de questões discursivas tais como: as responsividades inerentes ao projeto enunciativo do aluno-autor; as relações dialógicas entre o eu e o outro em tal situação de desafio à competência discursiva; as orientações, invariantes e variantes, do enunciado; o diálogo entre textos e a captação do estilo de gênero; o simulacro discursivo do enunciador; as relações entre estilo de gênero e estilo autoral. Observa-se que o processo de constituição do dizer memorialista reflete tendências constantes da recepção ativa do discurso do outro. Por conseguinte, há distintos modos de o aluno-autor articular as competências discursivas convocadas pelo enunciado. Há vozes que fazem sobressair os elementos composicionais e temáticos sugeridos pelo Caderno do Professor. Há vozes que, além do diálogo permanente com as orientações do Caderno, destacam-se pelo diálogo que as diferencia e as afasta das vozes do Caderno. Em todas está a projeção de posicionamentos valorativos e o modo peculiar de organizar o conteúdo e o material. Disso depreende-se a noção de densidade de presença autoral do aluno-autor, a qual vai de um gradiente menor, atenuando a presença autoral, a um grau maior e mais denso de presença. O estilo de gênero e o estilo autoral são modos de dizer em inter-relação. As recorrências na construção composicional e no conteúdo temático tendem a ser valorizadas quando se trata de estilo do gênero; as constâncias do modo de uso de tópicos temáticos, das relações dialógicas entre enunciados, das polêmicas instauradas pelos atores da enunciação remetem a um modo de presença do enunciador, o estilo autoral. Eis o estilo, conceito que, ao estabelecer as bases do sentido, delineia a imagem do sujeito discursivo. / The trends in Portuguese language teaching concerning Elementary Education in Brazil privilege linguistic and discursive approaches centered in the production, circulation and reception of texts. In consonance with these trends, this thesis investigates notions of genre style and authorship having as its object the Olimpíada de Língua Portuguesa Escrevendo o Futuro [Portuguese Language Olympiad - Writing the Future (OLPEF, 2008). OLPEF is one of the programs of public policies of incentive to reading and writing developed by means of didactic sequences for work with texts. The corpus of the research is the Instructors Manual Se bem me lembro... (2008) [If I remember well] and some texts of OLPEF, selected for the final turn of the competition regarding the texts gathered in the book Memórias (2008) [Memories]. The thematic unity of this corpus is therefore memories. In theoretical terms, the thesis has as its basis the Bakhtinian philosophy of language in correlation with some modern aspects of French discursive semiotics in order to solve questions that guide style in memorialist statements produced by pupils participating in the event, from which emerges the question of authorship in written productions of pupils in the context of OLPEF. For doing this, the thesis presents analyzes and reflections regarding discursive questions such as the inherent responsiveness of enunciative projects of pupils-authors; dialogical relationships between I and the other in such situation of challenge to discursive ability; invariant and variant orientations of utterances; the dialog among texts and the appropriation of genre style; the discursive simulacrum of enunciators; the relationships between genre style and authorial style. We observed that the process of constitution of memorialist enunciation reflects constant trends of active reception of the others discourse. Therefore, there are distinct ways for pupils-authors to articulate discursive abilities convoked by utterances. There are voices which emphasize compositional and thematic elements suggested by the Instructors Manual. There are voices which, in addition to permanently dialoguing with those instructions, are remarkable due to the dialog that differentiates them and make them go away from the voices of the Manual. In all of them there is the projection of evaluative positionings and a peculiar way of organizing the content and the material. From this we inferred the notion of density of authorial presence of pupils-authors, which goes from a lesser gradient, attenuating authorial presence, to a greater and denser degree of presence. Genre style and authorial style are ways of saying in inter-relation. Recurrences in compositional construction and thematic content tend to be valued when genre style is the focus; constancies in the ways of using thematic topics, of dialogical relationships among utterances, controversies created by actors of the enunciation point to a manner of presence of enunciators, namely, authorial style. This is style, a concept which, as it establishes the bases of sense, also delineates the image of discursive subjects.

O trabalho analisa a construção da visualidade no filme Serras da Desordem (2006) de Andrea Tonacci. As questões que guiam a pesquisa cercam a construção da visualidade fílmica através da investigação da filmografia do diretor, seu histórico, seu repertório. Paralelamente, buscou-se também aproximar a pesquisa de uma abordagem do cinema como resultado de uma colaboração. Também é explorada uma certa produção do cinema contemporâneo que faz ressonância com Serras da Desordem. Assim, aproximamos a produção de Tonacci dos filmes do diretor Rithy Pahn, S-21:The Khmer Rouge Killing Machine (2003) e LImage Manquante (2013), e de Joshua Oppenheimer, The globalization tapes (2003) e The Act of Killing (2012). Em comum, os filmes apresentam uma posição de crítica pós-colonial, exploração das fronteiras cinematográficas, rememoração e reencenação do passado, entre outras características. Para realizar nossa análise utilizamos os conceitos e autores que trabalham a estética relacional, a crítica de arte através da psicanálise, as idéias do Tercer Cine, a análise fílmica contemporânea, o documentário como obra de arte contemporânea, e as discussões que cercam o realismo e o documentário. Por fim, apresentamos um ensaio fílmico de nosso autoria, que dialoga com os filmes analisados. / This work analises the building visual style of Andrea Tonaccis movie Serras da Desordem (2006). The guide lines of this research relates to the filmic visual construction and investigates the directors filmography, history and repertoire. Besides, pursued also approximate the research to an approach that watches cinema as a result of collaborations. Equally, is explored a certain contemporary cinema scene wich is related to Serras da Desordem. Therefore, we approximate Andrea Tonaccis film production to directors like Rithy Pahn, S-21: The Khmer Rouge Killing Machine (2003) and LImage Manquante (2013), and Joshua Oppenheimer, The globalization Tapes (2003) and The act of killing (2012). In common, the movies have a post-colonial criticism, the exploration of cinematographic borders, recollection and reenactment of the past. To build our analysis we made use of authors and concepts wich think relational aesthetics, art criticism, psychoanalysis, the ideas of Tercer Cine, the contemporary film analysis, documentary as contemporary art, and the discussions about realism and documentary. Finally, a film essay that dialogues with the analysed movies is presented by the author of this research.

Nine students produced reflexive diaries about their learning experiences in the English language classes. Written in the foreign language they were in the process of learning, the students texts are narratives of their contradictions and doubts, but also of their discoveries in relation to their learning in general, to their learning of the foreign language, and in relation to themselves. The theoretical underpinnings for the work are studies in the areas of identity construction (Wenger, 1998; Moita Lopes, 1998, 2002; Gee, 2000; Orlandi, 1998); education (Dewey, 1938/1963; 1916/1967; Giussani, 2004; Bruner, 1976, 1995); genres and reflexive diaries (Machado, 1998, 2005; Liberali, 1999). Equally relevant are authors such as van Manen (1990), Frankl (1997) e Quintás (1995, 2003) who, under different perspectives, also contribute to a better understanding of factors involved in the construction of the students as people and as authors. Based on the hermeneutic-phenomenological paradigm (Ales Bello, 2004; van Manen, 1990; Gadamer, 1975; Ricoeur, 2002), the data were analysed with the purpose of understanding and interpreting the learning stories present in the diaries, and the effect of the lived experiences on the students identities. Individual and shared learning stories are found, which point to three kinds of relations that help construct their identities as students: the interactions they live or seek with the teacher and their classmates; with the materials and activities proposed; with their own (present and past) learning experiences in the foreign language / Esta pesquisa tem como objetivo investigar o fenômeno de construção da identidade de alunos de primeiro ano de um curso de Letras: inglês. Durante um semestre, nove alunos produziram diários reflexivos sobre suas experiências de aprendizagem nas aulas de Língua Inglesa. Escritos na própria língua estrangeira que estavam aprendendo, seus textos são narrativas de suas contradições e dúvidas, e de descobertas e constatações que fizeram sobre o aprender, sobre seu aprender inglês, sobre si mesmos. Ajudam a compor a fundamentação teórica do trabalho autores que discorrem sobre a formação da identidade (Wenger, 1998; Moita Lopes, 1998, 2002; Gee, 2000; Orlandi, 1998); sobre educação (Dewey, 1938/1963; 1916/1967; Giussani, 2004; Bruner, 1976, 1995); sobre o gênero diário reflexivo (Machado, 1998, 2005; Liberali, 1999). Entre muitos outros, destacam-se ainda van Manen (1990), Frankl (1997) e Quintás (1995, 2003) que, sob perspectivas diversas, colaboram para a compreensão de fatores envolvidos na constituição da pessoa do aluno e de seu dizer. A análise dos dados, desenvolvida dentro da perspectiva hermenêutico-fenomenológica (Ales Bello, 2004; van Manen, 1990; Gadamer, 1975; Ricoeur, 2002), buscou compreender e interpretar as histórias de aprendizagem contadas nos diários, e o efeito das experiências vividas sobre a identidade dos alunos. Histórias de aprendizagem individuais e compartilhadas são encontradas, as quais apontam para três salientes tipos de relações que contribuem para compor a identidade dos alunos: as interações que vivem ou buscam com o professor ou colegas; com os materiais e atividades propostos; e com as próprias experiências (presentes e passadas) de aprendizagem da língua estrangeira

The general objective of the research is to contribute to the study of the textual production in the school, and its specific objectives are to identify the linguistic marks of authorship and the process of argumentative texts in the high school student s texts and, then, to present suggestions for directed activities to the practice of textual production in the classroom. The research is justified by the concern with the textual production-oriented to the positioning of the individual writer as an author of his own texts, considering his argumentative competence. The work hypothesis is that by placing himself as author of his text, the subject becomes a writer capable of a consistent argumentation, considering the critical positioning on a specific topic. The research, based on theoretical principles of the Textual Analysis of Discourse and the Argumentative and Rhetorical Studies, analyzes a corpus composed by texts of a high school students of a public school of the educational network of São Paulo. The textual productions were analyzed according to two categories of analysis, having been identified marks of authorship and the argumentative process in the printed texts of the students. The survey results indicate that, in the analyzed texts, the authorship and the argumentation are marked by means of language resources based mainly on the notions of proximity, intensity and frequency, both in the linguistic and the rhetorical aspects. By the end of the work, suggestions of activities are presented aiming the development of the textual production in a classroom, considering the critical positioning of students in the consolidation processes of authorship and argumentation / O presente trabalho tem como tema a autoria e a argumentação em textos do Ensino Médio. O objetivo geral da pesquisa é contribuir para os estudos da produção textual no espaço escolar, e seus objetivos específicos são identificar as marcas de autoria e do processo argumentativo em textos de alunos do Ensino Médio para, em seguida, apresentar sugestões de atividades direcionadas à prática de produção textual na sala de aula. A pesquisa justifica-se pela preocupação com a produção textual orientada para o posicionamento do sujeito escritor como autor de seus textos, tendo em vista sua competência argumentativa. A hipótese do trabalho é de que, ao colocar-se como autor de seu texto, o sujeito escritor se torna capaz de uma argumentação consistente, tendo em vista o posicionamento crítico acerca de um tema. A pesquisa, fundamentada em princípios teóricos da Análise Textual dos Discursos e dos Estudos Retóricos e Argumentativos, analisa um corpus formado por textos de alunos do Ensino Médio de uma escola pública da rede de ensino do Estado de São Paulo. As produções textuais foram analisadas de acordo com duas categorias de análise, tendo-se identificado marcas de autoria e de argumentação impressas nos textos dos estudantes. Os resultados da pesquisa indicam que, nos textos analisados, a autoria e a argumentação são marcadas por meio de recursos linguísticos baseados, principalmente, nas noções de proximidade, de intensidade e de frequência, tanto nos aspectos linguísticos quanto nos aspectos retóricos. Ao final do trabalho, são apresentadas sugestões de atividades para o desenvolvimento da produção textual em sala de aula, tendo em vista o posicionamento crítico dos estudantes na consolidação dos processos de autoria e de argumentação
