No. of bitstreams: 1 Jose Mario de Oliveira Mendes.pdf: 1469321 bytes, checksum: 9e975a9431dd94f9b37aa1581e352e24 (MD5) Previous issue date: 2013-05-24 / This research, insert into the context of SAL Project - Systemics Across Languages - aims at investigating the use of verbal processes in scientific articles produced in the areas of Business Administration and Engineering assuming the theoretical framework of the Systemic Functional Linguistics formulated by Halliday (1985) and Halliday & Matthiessen (2004) which proposes to investigate the structure of the language in use in different contexts. With focus on the ideational metafunction, specifically in verbal processes, we show the patterns of realization of these processes, the similarities and the differences between these areas of study. With the support of the computational tool WordSmith Tools 5.0, we organize data collected from 266 scientific articles published in the site SciELo Brazil, being able to observe information as frequency of occurrence and patterns of message realization of each process classified as verbal in the contexts they occur in our corpus. We intend, with this research, to contribute to providing more data which may serve to fill a gap in the description of Brazilian Portuguese and results which could be used by readers, researchers and academics as an additional tool of support and research when reading, producing and interpreting scientific articles / Esta pesquisa, inserida no contexto do projeto SAL Systemics Across Languages - tem como objetivo investigar o uso dos processos verbais em artigos científicos produzidos nas áreas de Administração de Empresas e Engenharia utilizando os pressupostos teóricos da Linguística Sistêmico-Funcional formulada por Halliday (1985) e Halliday & Matthiessen (2004) que tem como proposta a investigação da estruturação da língua em uso em diferentes contextos. Com foco na metafunção ideacional, mais especificamente nos processos verbais, mostramos quais os padrões de realização desses processos, as semelhanças e as diferenças entre essas áreas de estudo. Com o apoio da ferramenta computacional WordSmith Tools 5.0, organizamos dados coletados de 266 artigos científicos das áreas em questão nesta pesquisa publicados no site SciELo Brasil, podendo observar dados como frequências de ocorrência e padrões de realização de mensagem de cada processo classificado como verbal no contexto em que ocorrem em nosso corpus de estudo. Pretendemos com esta pesquisa, contribuir com o fornecimento de dados que possam servir para o preenchimento de mais uma lacuna na descrição do português brasileiro e resultados que possam ser utilizados por leitores, pesquisadores e acadêmicos como mais um instrumento de apoio e pesquisa quando da leitura, produção e interpretação de artigos científicos

No. of bitstreams: 1 Fernanda Beatriz Caricari de Morais.pdf: 1235029 bytes, checksum: a4842e0640645795dfe41ccd69dd81bc (MD5) Previous issue date: 2013-06-20 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / This study is part of SAL - Systemics Across Languages, a project, developed in association with researchers from China, Argentina, Mexico, Colombia and Thailand, whose aim is to study specific and universal features of languages. In Brazil, it project focuses mainly the study scientific language. This dissertation aims to analyze the different uses and functions of the clitic se. This study excluded se when functioning as a reflexive pronoun or as a conjunction since their uses are clearly described and they are not related with the focus of this investigation: defocus of the participant and creation of agnates. The data, SAL project s data, consists of 1225 scientific papers from many areas of knowledge collected from Scielo database. Se functions typically as a grammatical item in a number of uses, therefore, one of the most interesting problems in Portuguese and others language such as French, Spanish and Italian. One of the controversies about this clitic is its possibility, in all those languages, of the participant being clearly expressed or not, as discussed in Nunes (1991), Monteiro (1994), Bagno (2000), Camacho (2002, 2003), or others with respect to Portuguese or Ruwet (1972), Suñer (2002) and Cinque (1988) for other languages. The theory underlying this research, Systemic Functional Linguistics (Halliday, 1994, 2004), focuses language in use and analyzes the grammatical choices in texts (spoken or written) based on their context of culture and of situation. This thesis shows se occurs in three categories: in middle constructions (self-caused process); in constructions that defocus participants, and in agnate constructions. We hope this description helps material and courses designers focusing production or comprehension of academic texts specifically and other context of occurrences / Este trabalho está inserido em um contexto maior, o projeto SAL (Systemics Across Languages) desenvolvido em parceria com pesquisadores da China, Argentina, México e Tailândia que procuram entender as características específicas e universais que partilham as línguas. No Brasil, o projeto visa estudar a linguagem de artigos científicos. Esta tese objetiva analisar os diferentes usos e funções que o clítico se desempenha em artigos científicos. As funções excluídas são: o reflexivo e a conjunção, pois seus usos são claramente descritos e não estão relacionados ao desfocamento de participante e com construções agnatas. O corpus de estudo, corpus do projeto SAL, contém 1225 artigos científicos de diversas áreas do conhecimento coletados da plataforma Scielo. A multiplicidade de funções é uma das características do se, um dos problemas mais interessantes da língua portuguesa e de outras como francês, espanhol e italiano. Uma das controvérsias em torno desse clítico é a possibilidade de o participante estar ou não indeterminado, como discutem as pesquisas de Nunes (1991), Monteiro (1994), Bagno (2000), Camacho (2002, 2003), entre outros. O mesmo ocorre com o on em francês, se em espanhol e si em italiano, conforme trabalhos de Ruwet (1972), Suñer (2002) e Cinque (1988). A base teórica, a Linguística Sistêmico-Funcional de Halliday (1994, 2004), tem como foco a língua em uso e permite analisar as escolhas gramaticais do autor em textos (escritos ou falados) com base no contexto de cultura e de situação em que se realizam. Segundo a proposta desta tese, os usos do se podem ser classificados em três categorias: se em construções médias as ações que acontecem por si só, um processo é causado por ele mesmo (self-caused process); se em construções com desfocamento de participante que ocorrem por ser irrelevante sua menção, parte do estilo do gênero acadêmico/científico e se em construções agnatas verbos que quando se ligam ao se têm significados relacionais e/ou existenciais. Espera-se que este pesquisa contribua com os estudos sobre o uso desse clítico em língua portuguesa e, também, auxilie na elaboração de materiais didáticos e de cursos instrumentais que visam atender a produção e compreensão escrita de textos acadêmicos

Made available in DSpace on 2016-04-28T18:22:41Z (GMT). No. of bitstreams: 1 Maria Aparecida da Silva Lamas.pdf: 1841133 bytes, checksum: 512ddc4f034f38e4d0997d0d9c8917b9 (MD5) Previous issue date: 2013-06-19 / Conselho Nacional de Desenvolvimento Científico e Tecnológico / This research aims at analysing the discourse of ribeirinha communities located across São Francisco River in order to identify patterns of beliefs and social values. Who are the people living riverside? Which social realities bound them together? Which representations build the society they are in? The language choices made when we are part of a given discourse are not arbitrary; they are filled with the speaker s identity, her meanings and beliefs. The theoretical background of this research lies on the Systemic Functional-Linguistics (Halliday, 1994, 2004), since the analysis carried on focuses on the System of Transitivity. Here we address the corpus from a perspective which recognizes language as a social phenomenon, since this study establishes a dialogue with other areas such as anthropology, sociology and cultural studies. The research corpus is a number of interviews collected in ribeirinha communities across São Francisco riverside, taken from 2005 through 2008 by the photojournalist João Zinclar. The interviews took place in communities which were located in the five states which border the river, at the time was the controversy over the transposition of the water from the river. The analysis revealed a strong sense of sense of community by the ribeirinhos. It has also shown a strong feeling of proud, result of the fact they are part of a social/ethnic group (Indians, quilombola etc.). Their territory the riverside is responsible for mediating the relationship across the many communities. On the other hand, it was clear such communities are suffering deterritorialization, losing the place where they affective and symbolic values were conceived. This has created a great feeling of anguish and distress felt by the ribeirinha communities and resulting in situations of social conflict / Este trabalho tem como objetivo analisar o discurso de comunidades ribeirinhas localizadas na extensão do rio São Francisco, identificando padrões de crenças e valores. Quem são as pessoas que habitam as margens do rio? Que tecidos sociais os unem? Que relações estabelecem com o rio? Que representações constroem da sociedade nos quais estão inseridos e do mundo contemporâneo? As escolhas linguísticas feitas quando se produz um discurso não são arbitrárias, são carregadas pela identidade do falante, suas significações e crenças.. A Linguística Sistêmico-Funcional (Halliday, 1994, 2004) é a linha teórica em que se ancora este trabalho, analisando os dados em termos do Sistema de Transitividade, adotando-se a perspectiva de linguagem como fenômeno social. Numa perspectiva transdisciplinar, dialoga com outras áreas como a antropologia, sociologia e estudos culturais. O corpus da pesquisa é composto por relatos e depoimentos coletados em comunidades ribeirinhas do rio São Francisco, no período de 2005 a 2008, pelo repórter fotográfico João Zinclar. As entrevistas foram feitas em comunidades localizadas nos cinco estados banhados pelo rio, na época em que se dava a polêmica sobre a transposição das águas do rio. A análise dos dados evidenciou que o senso de coletividade constitui-se um dos principais traços das comunidades ribeirinhas. Também revelou um forte sentimento de pertencimento e orgulho em fazer parte de um determinado grupo (indígena, quilombola etc). O território as margens do rio - é o responsável pela mediação entre as várias comunidades. Por outro lado, ficou patente que a desterritorialização do lugar onde foram concebidos os valores afetivos e simbólicos provoca grande angústia nos Ribeirinhos, gerando situações de conflito social

Resenhas acadêmicas: caracterização do gênero nas áreas de Linguística, Literatura e História, à luz da Linguística Sistêmico-Funcional

Silva, Aline Cristina Flávio da 03 April 2014 (has links)
Made available in DSpace on 2016-04-28T18:22:50Z (GMT). No. of bitstreams: 1 Aline Cristina Flavio da Silva.pdf: 786298 bytes, checksum: 84a114cc3daba9c2fd3f6d8fb92f3fa0 (MD5) Previous issue date: 2014-04-03 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / This research is part of SAL Project - Systemis Across Languages - which has been developed by researchers from China, Argentina, Mexico and Thailand who analyse language in use having specific texts as a starting point in order to find out patterns as well as varieties of use. In Brazil, researches have focused on academic papers. Therefore, in order to contribute to the researchers developed in Brazil, the objective of this study is to identify the uses of verbal and mental processes in reviews published in the areas of Linguistics, Literature and History, analyse the patterns of realization of these processes in order to better understand how the reviewer conveys his description/evaluation of a certain book, and the role of modal adjuncts in meaning making. Systemics Functional Linguistics is the main theoretical and methodological framework (Halliday, 1985, 1994; Halliday & Matthiessen, 1999, 2004), which focus is language in use in different contexts. The software WordSmith Tools 5.0 allowed 45 reviews of Linguistics, 47 reviews of Literature and 46 reviews of History, all of them available electronically and qualified as Qualis A1 and A2 to be processed so that data were organized for analysis. Based on the transitivity system through which the ideational metafunction is accessed, the most frequent verbal and mental processes in the reviews from the three different areas were selected and their similarities and differences were compared. It was observed that the uses of verbal and mental processes in the reviews from the three areas mentioned are, most of the time, associated to a higher engagement of the reviewer who prioritizes a more elaborated use of the language, making use of verbiage which construes the content of what is said and reduces the clause. As far as choices of Sayers and Sensers are concerned, there is evidence of high interaction with the reader. Concerning the interpersonal metafunction, modal adjuncts of polarity, intensity and temporality were identified in the corpora. They accompany verbal and mental processes and highlight the engagement of the reviewer with his text when negotiating with the reader. This research is expected to contribute to the studies about the genre review written in Portuguese, providing background for those who intend to produce this genre in the areas hereby mentioned / Esta pesquisa está inserida no contexto do projeto SAL- Systemis Across Languagesdesenvolvido em parceria com pesquisadores da China, Argentina, México e Tailândia que analisam a linguagem em uso partindo de tipos específicos de textos buscando constantes e variáveis. No Brasil, as pesquisas se voltam para textos acadêmicos. Assim, buscando contribuir com essas pesquisas, esta dissertação tem como objetivo identificar os usos dos processos verbais e mentais utilizados em resenhas das áreas de Linguística, Literatura e História e analisar os padrões de realização desses processos para compreender como o resenhista expõe sua descrição/avaliação da obra resenhada e como os Adjuntos modais associam-se aos processos nessa construção. Utilizando o arcabouço teórico da Linguística Sistêmico-Funcional (Halliday, 1985, 1994; Halliday & Matthiessen, 1999, 2004), que tem como foco a língua em uso em diferentes contextos e, com o apoio da ferramenta computacional WordSmith Tools 5.0, organizei os dados constantes de 45 resenhas de Linguística, 47 de Literatura e 46 de História, publicadas em periódicos disponibilizados eletronicamente, qualificados como qualis A1 e A2. Com base no sistema de transitividade da metafunção ideacional, selecionei os processos verbais e mentais mais frequentes nas três áreas e comparei as semelhanças e diferenças entre elas. Observei que os usos dos processos verbais e mentais, nas três áreas, em sua maioria estão associados ao maior envolvimento do resenhista priorizando a linguagem mais elaborada constituída pelo uso da verbiagem de conteúdo em que há sintetização da oração. Ao que se refere às escolhas dos Dizentes e Experienciadores há indícios de maior interação com o leitor. Baseada na metafunção interpessoal, levantei os adjuntos modais presentes nos corpora e verifiquei que os modais de polaridade, intensidade e temporalidade são os que estão mais associados aos processos verbais e mentais e contribuem para ressaltar o maior envolvimento do resenhista com o texto na negociação com o leitor. Espero que esta pesquisa contribua com os estudos sobre o gênero resenha em língua portuguesa auxiliando pesquisadores que pretendam desenvolver esse gênero nas áreas aqui pesquisadas

[en] THE OHESIVE FUNCTION OF NOMINALIZATIONS IN STUDENTS’ WRITTEN PRODUCTION: A SYSTEMIC-FUNCTIONAL PERSPECTIVE / [pt] A FUNÇÃO COESIVA DAS NOMINALIZAÇÕES EM REDAÇÕES ESCOLARES NA PERSPECTIVA SISTÊMICO-FUNCIONAL

RUBIANE GUILHERME VALERIO 04 February 2014 (has links)
[pt] Este estudo tem como objetivo investigar a função coesiva desempenhada pelas nominalizações em redações de alunos do terceiro ano do Ensino Médio. Para tanto, esta pesquisa baseia-se nos pressupostos da Linguística Sistêmico- Funcional, que compreende a língua como um sistema sociossemiótico em função dos contextos situacionais e culturais em que ela é utilizada (Halliday, 1994). O estudo das nominalizações é também relacionado ao fenômeno da metáfora gramatical ideacional, uma das características da escrita acadêmica (Simon- Vandenbergen et al, 2003, Banks, 2003). O corpus de estudo consiste em 45 redações de instituições de três segmentos escolares – federal, estadual e particular – e perfaz um total aproximado de 9800 palavras. A análise foi conduzida em duas etapas: uma quantitativa, com apoio de ferramentas computacionais (Scott, 2004), em que se buscou a frequência de uso das nominalizações nos textos analisados, assim como a variação desse uso entre os textos das diferentes escolas; e outra qualitativa, que teve por objetivo descrever os tipos de elos coesivos estabelecidos pelas formas nominalizadas nas redações selecionadas para esta pesquisa. Os resultados mostram que os alunos usam as nominalizações como elemento coesivo e que há considerável variação desse uso em função das diferentes escolas em que esses textos foram produzidos, fazendo com que os textos apresentem diferentes níveis de adequação ao contexto escolar. Mais especificamente, através da análise dos resultados pode-se identificar e classificar diferentes tipos de elos coesivos constituídos pelas nominalizações, os quais apresentam alguns padrões de realização distintos dos já revelados por estudos anteriores sobre a coesão (Halliday e Hasan, 1989, Fávero, 1991, Koch, 1993), incluindo a realização de laços coesivos entre nominalizações como núcleo de um sintagma nominal e outros sintagmas de maior complexidade lexical e semântica. A partir desses resultados, espera-se que este estudo não só contribua para uma descrição mais apurada de alguns padrões de uso da língua portuguesa, mas também para o ensino da escrita no contexto escolar, já que também são brevemente discutidas neste trabalho algumas implicações pedagógicas quanto à função coesiva das nominalizações, as quais podem levar a uma maior conscientização sobre os padrões linguísticos e textuais considerados como adequados especialmente aos gêneros do contexto pedagógico. / [en] The objective of this study is to investigate the cohesive function of nominalizations in the written production of secondary school students. For this purpose, this research is based on theoretical assumptions from Systemic- Functional Linguistics, which considers language as a socio-semiotic system, related to the situational and cultural contexts in which language is used (Halliday, 1994). The study of nominalizations can also be associated to the phenomenon of ideational grammatical metaphor, which is viewed as one of the characteristics of academic writing (Vandenbergen-Simon et al, 2003, Banks, 2003). The corpus of study consists of 45 essays of three educational institutions - federal, state and private – totalizing approximately 9800 words. The analysis was conducted in two stages: a quantitative corpus-based approach, with the support of computational tools (Scott, 2004), to calculate the frequency of nominalizations in the analyzed texts, as well as their variation of use in the texts from different schools; and a qualitative approach, which aimed at the description of the types of cohesive ties established by nominalized forms in the selected essays. Results show that students use nominalizations as a cohesive element and there is considerable variation concerning this use, according to the different schools where texts were produced. This variation makes student texts present different levels of appropriateness to the school context. More specifically, through data analysis, it was possible to identify and classify different types of cohesive ties, constituted by nominalizations, which present linguistic patterns that differ from those that were previously revealed in other cohesion studies (Halliday and Hasan, 1989, Fávero, 1991 Koch, 1993), including the realization of cohesive ties between nominalizations as the head of a noun phrase and other phrases that are lexically and semantically more complex. In addition, this study is expected to contribute not only to a more accurate description of nominalizations, but also to the teaching of writing at school level, since it briefly discusses some pedagogical implications of the cohesive function of this linguistic feature, which can lead to a greater awareness of textual standards considered adequate to genres in several pedagogical contexts.

As Fate Would Have It : A corpus-based study of Fate from an American perspective

Kanmert, Sofi January 2009 (has links)
<p><strong>Abstract</strong></p><p>This essay is based on an investigation carried out with the help of the Corpus of Contemporary American English (COCA). Taking the system of transitivity as its theoretical base and using spoken and written discourse as its primary source, this study aspired to find out what kinds of actions Americans perceive <em>Fate</em> to perform, for example physical, mental or verbal,<em> </em>in order to control what happens to people. It also aimed to reveal what actions people are said to perform in their attempts to control <em>Fate</em>. Do Americans deem <em>Fate</em> capable of, for instance, “deciding”, “talking” or “conspiring” and do they say that people, for example, “challenge”, “defy” or “defeat” <em>Fate</em>? Furthermore, a comparison was made in terms of the actions performed by <em>Fate</em> and people between the different domains of discourse represented in the corpus: spoken, fiction, magazine, newspaper and academic.</p><p>Among other things, this investigation shows that in American discourse both <em>Fate</em> and people are perceived to resort to physical strategies rather than mental or verbal ones in their endeavor to control one another.</p><p> </p>

Fri översättning i det medeltida Västnorden / Free Translation in Medieval West Nordic Society

Pettersson, Jonatan January 2009 (has links)
In this thesis, medieval free translation is explored as a text-producing practice as it appears in Alexanders saga, a 13th century Old Norse translation of the medieval Latin epic Alexandreis. The practice is investigated through analyses of (1) the rendering of the source text and (2) the translator’s role in making the target text. The rendering is analyzed through a systematic comparison between source and target text using a method of analysis based on systemic functional linguistics (SFL). Contrary to what was assumed previously, the rendering pro­ves to be consistent in the text, but a surprising result is that the rendering in chapters 2–4 and in chapters 1 and 6–10 respectively represent two significantly dif­ferent patterns, the former being closer to the source text than the latter, pre­sumably due to two different translators. The investigation further confirms an observation in previous research on Old Norse free translation that the rendering of parts in direct speech are closer to the source than that of narrative and descriptive discourse. The rendering is closest where the translator indicates that he is quoting the author of the source text. These patterns are found in both groups of chapters, and as they are confirmed in other Old Norse translations, they might be interpreted as a translation norm. The conceptions of translation are further investigated by examining what kind of text-producing role the translator assumes. It is claimed that, despite the freedom in free ren­dering, the translator assumes the role of intermediary between the source text and the receivers of the target text rather than the role of independent text pro­ducer. From an analysis of the translator’s metatextual additions, it seems as though this is also what the translator assumes the receivers of the text expect him to do. The results indicate the presence of certain conceptions of how translation was to be carried out in West Nordic society. The ”free” translation strategies did not mean freedom from or obliviousness to translation norms, but rather re­late to a specific text-producing practice.

A contextual analysis of compound nouns in Shona lexicography

Mheta, Gift January 2011 (has links)
This research is in the area of lexicography and investigates the relationship between Shona terminology development and the culture of the language community for which the terminology is intended. It is a contextual analysis of compound nouns found in Shona terminological dictionaries. The study specifically explores how lexicographers together with health, music, language and literature specialists make use of their knowledge about Shona cultural contexts in the creation of compound nouns. Thus, this research foregrounds Shona socio-cultural contexts and meaning generation in terminology development. This study employs a quadruple conceptual framework. The four components of the framework that are utilised are the Traditional Descriptive Approach (TDA), Cognitive Approach (CG), Systemic Functional Approach (SFL), and Semiotic Remediation (SRM). TDA is used in the linguistic categorisation of Shona compound nouns. In addition, it provides the metalanguage with which to describe the constituent parts of Shona compound nouns. As TDA is mainly confined to the linguistic dimension, this research employs CG, SFL, and SRM to explore the cultural and socio-cognitive dimensions of terminology development.

Ο λόγος της Ιστορίας και της Βιολογίας στα σχολικά εγχειρίδια του Γυμνασίου : κειμενικά είδη και συστημική λειτουργική ανάλυση

Παπαγιαννόπουλος, Ιωάννης 01 February 2013 (has links)
Σκοπός της εργασίας είναι η διερεύνηση των γλωσσικών χαρακτηριστικών στα κειμενικά είδη που εμφανίζονται στα σχολικά εγχειρίδια της Ιστορίας και της Βιολογίας του γυμνασίου, με βάση το θεωρητικό πλαίσιο και τη μεθοδολογία της Συστημικής Λειτουργικής Γλωσσολογίας (ΣΛΓ). Συγκεκριμένα, αναλύονται οι λεξικoγραμματικοί πόροι και τα σημασιολογικά χαρακτηριστικά σε είκοσι τέσσερα συνολικά κείμενα από τα σχολικά εγχειρίδια. Η έρευνα εστιάζει στις διαδικασίες και τους μετέχοντες (σύστημα μεταβιβαστικότητας), στη λεξική πυκνότητα, στην τροπικότητα, στη γραμματική μεταφορά (ιδίως στην ονοματοποίηση), στην χρονικότητα και την αιτιότητα και στις συνδετικές σχέσεις. Οι διαφοροποιήσεις του λόγου των ανθρωπιστικών και φυσικών επιστημών, η αφαίρεση και η τεχνικότητα, και τα σύνδρομα χαρακτηριστικών που χαρακτηρίζουν τα κειμενικά είδη, εξετάζονται σε συσχέτιση και με τα ευρήματα συναφών ερευνών που έχουν γίνει τόσο στην Ελλάδα όσο και διεθνώς (κυρίως στην Αυστραλία). Όπως προκύπτει από την ανάλυση των αποτελεσμάτων, τα χαρακτηριστικά αυξάνονται από τη μία τάξη στην άλλη και εντοπίζονται διαφορές στα δύο αντικείμενα. Η ανασυγκρότηση της γνώσης απαιτεί από τα παιδιά του γυμνασίου εξοικείωση με τις γραμματικές μορφές της γραπτής γλώσσας και του τρόπου που αναπτύσσονται στα κειμενικά είδη στα διάφορα μαθήματα. Επιπλέον, προτείνεται η συστηματικότερη ανάλυση και προσαρμογή των εργαλείων της ΣΛΓ στην ελληνική γλώσσα, δεδομένου ότι έχει εφαρμοστεί κατά κύριο λόγο στην αγγλική, και, τέλος, γίνονται κάποιες προεκτάσεις στην εκπαίδευση και τον γραμματισμό με γνώμονα μια ισονομιστική και χειραφετητική γνώση. / The purpose of this study is to investigate the language of genres in History and Biology school textbooks in early secondary school (gymnasio), within the frame of systemic functional linguistics (SFL). More specifically, our aim is to analyze the lexicogrammar and semantics of twenty four texts from school textbooks. The study focuses on processes and participants (system of transitivity), lexical density, modality, grammatical metaphor (especially nominalization), temporality, causality and conjunctive relations. Differences in discourse of humanities and natural sciences, technicality and abstraction, and the co-occurrence (syndromes) of characteristics in different genres are considered in relation with the findings of relevant Greek and international researches. According to data analysis, there is an increasing tension from lower to higher grade and some differences between the two subject areas. The reconstruction of knowledge demands from early secondary pupils familiarization with grammatical forms of written language and with the way that they are deployed in school genres. Furthermore, it is suggested more specific analysis and adaptation of SFL tools in Greek language, given that they have implemented basically in English, and, finally, our remarks are extended to education and literacy under the rule of equal opportunities and emancipative knowledge.
