[pt] Este trabalho estuda o uso do metadiscurso em artigos pesquisa em diferentes culturas, áreas disciplinares e seções do artigo, tendo como objetivo investigar como esse recurso retórico varia em contextos lingüísticos e sócio-culturais diversos, contribui para a construção de sentido de textos escritos e reflete a construção de conhecimento em diferentes áreas disciplinares. A pesquisa adota como base teórica a abordagem sociointeracional de linguagem, a teoria da construção social do conhecimento e princípios da retórica contrastiva. O corpus utilizado compõe-se de 24 artigos científicos, divididos em duas línguas (português e inglês), duas áreas disciplinares (Ciências Biomédicas e Lingüística, Letras e Artes) e quatro seções (Introdução, Metodologia, Resultados e Discussão). O estudo da variação entre os textos escritos em inglês e português mostrou que há diferenças quanto ao uso de itens metadiscursivos que enfocam a micro ou a macroorganização do artigo de pesquisa. A variação interdisciplinar mostrou que o texto pode ser escrito de forma subjetiva ou objetiva, e que o conhecimento nas diferentes comunidades disciplinares pode ser construído com base em idéias ou fatos. Quanto às seções dos artigos, verificou-se que o uso do metadiscurso varia para alcançar objetivos retóricos diferenciados de acordo com a seção do artigo. Esta pesquisa reforça a possibilidade e necessidade de enfocar o metadiscurso e a linguagem sob uma ótica sociointeracional, confirmando que a escrita acadêmica é interativa e mostrando que a construção de sentidos de textos e a construção de conhecimento variam em diferentes culturas e comunidades disciplinares. / [en] This research studies the use of metadiscourse in research articles in different cultures, disciplinary areas and article sections, aiming at investigating how this rhetorical device varies in different linguistic and socio- cultural contexts, contributes to the construction of meaning in written texts and reflects the construction of knowledge in different disciplinary areas. This work adopts as theoretical basis a sociointeractional approach to language, the theory of social construction of knowledge and principles of contrastive rhetoric. The research corpus is composed of 24 scientific articles, divided into two languages (Portuguese and English), two disciplinary areas (Biomedical Sciences and Linguistics, Letters and Arts), and four sections (Introduction, Methodology, Results and Discussion). The study of variation between texts written in English and Portuguese shows that there are differences in the use of metadiscourse items which can focus on micro or macroorganization of the scientific article. Interdisciplinary variation shows that scientific texts can be written either in a subjective or objective manner, and that knowledge construction in different disciplinary communities can be based either on ideas or facts. As to research article sections, this study shows that the use of metadiscourse varies according to writers´ intention to reach rhetorical objectives in each section. This research study reinforces both the possibility and necessity to focus on metadiscourse and language under a sociointeractional perspective, confirming that academic writing is interactive, and showing that the construction of meaning in texts and the construction of knowledge vary in different cultures and disciplinary communities.

Cette thèse, qui relève de la didactique du français langue étrangère, traite des conventions d’écriture académique en français et en chinois dans une perspective de rhétorique contrastive. Nous étudions deux genres académiques propres à l’enseignement supérieur en France et en Chine : la dissertation et le yilun wen, respectivement. Les deux exercices détiennent un statut comparable ; ils obéissent tous deux à un système de normes relativement stables, à une structure clairement fixée et font figure d’ « exercice-roi » dans chacune des deux cultures éducatives. La comparaison entre ces deux genres scolaires et universitaires nous permet d’analyser les difficultés rencontrées par un groupe d’étudiants chinois en FLE dans la rédaction d’une dissertation et les transferts qu’ils opèrent en français des conventions d’écriture issues du yilun wen. Cette analyse est éclairée par celle des annotations marginales portées sur leurs copies de dissertation par des correcteurs français. A travers les résultats d’une enquête menée par questionnaire auprès de groupes d’étudiants (chinois et français), la thèse s’attache ensuite aux représentations très disparates que les deux ensembles de groupes se font de la signification de ces normes du point culturel et cognitif.La thèse s’attache enfin à décrire la rhétorique traditionnelle chinoise à travers l’analyse du bagu wen et du schéma Qi-Cheng-Zhuan-He, un dispositif traditionnel toujours proposé dans les manuels et pratiqué par les étudiants. / This study compares academic writing conventions in French and Chinese from the point of view of Contrastive Rhetoric in the field of French teaching and learning as a foreign language. We spot respectively in French and Chinese education systems a specific genre: the French dissertation and the Chinese yilun wen. They have a comparable status, a clear structure and strict rules to follow. The comparison between these two genres indicates that the rules are not shared between French and Chinese students and that certain criteria required in the Chinese yilun wen appear far removed from French dissertation. Thus Chinese students encounter intricate difficulties in writing French dissertations and negative transfers under the influence from Chinese writing conventions. This result is also confirmed by the analysis of dissertations written by the Chinese students of our corpus. The surveys conducted among French and Chinese learners show that they are not fully aware of the cultural differences of standards in writing. The analysis of comments by French teachers of dissertation written by Chinese students shows that they are not better armed than their students in face of the differences of textual organization (both the construction and the way of realization) in French and Chinese. We attend to hold endly how the organization of traditional Chinese Rhetoric (the bagu wen and the Qi-Cheng-Zhuan-He schemes), still proposed by textbooks and practiced by learners, exert more or less influence on French writing of the Chinese students.

La presente tesis doctoral tiene como propósito el estudio del fenómeno sociopragmático llamado atenuación retórica (hedging en inglés) en dos géneros distintos del discurso médico escrito: los artículos de investigación científica y los informes de caso o casos médicos. Con este fin se examina un corpus de ambos géneros escritos en español y en inglés (L2) por científicos españoles y publicados en revistas científicas de prestigio en el campo de la biomedicina . Se comparan los resultados obtenidos del análisis del corpus con los obtenidos por otros autores con muestras lingüísticas escritas en inglés. El trabajo, pues, consiste en un análisis interlingüístico e intergenérico de la atenuación retórica en el discurso médico. Un interés particular que presenta la tesis reside en las aplicaciones pedagógicas que tiene para los profesores de enseñanza de idiomas con fines específicos (LFE). / La present tesi doctoral té com a objectiu l'estudi del fenòmen sociopragmàtic anomenat atenuació retòrica (hedging en anglès) en dos gèneres diferents del discurs mèdic escrit: els articles d' investigació científica i els informes de cas o casos mèdics. Amb aquesta finalitat s' examina un corpus en ambdós gèneres escrits en espanyol i en anglès (L2) per cientifics espanyols i publicats en revistes científiques de prestigi en el camp de la biomedicina . Es comparen els resultats obtinguts de l'anàlisis del corpus amb els obtinguts per altres autors amb mostres lingüístiques escrites en anglès. El treball, doncs, consisteix en una anàlisi interlingüística i intergenèrica de la atenuació retòrica en el discurs mèdic. Un interès particular que presenta la tesis resideix en les aplicacions pedagògiques que té pels professors d' ensenyament d' idiomes per a finalitats específiques (LFE). / This PhD aims at studying the sociopragmatic phenomenon called hedging in two different genres of the written medical discourse: the research article and the case report. Therefore, a corpus of these two genres is examined both in Spanish and in English (L2). Being all texts written by Spanish scientists and published in scientific journals of prestige in the biomedical field . The results obtained in the corpus analysis are then compared to the ones obtained by other authors with similar linguistic samples written in English. This thesis, hence, consists of itergeneric and interlinguistic analyses of hedging in medical disourse. A special interest of this research project may lay in the pedagogical applications for teachers of languages for specific purposes (LSP).
