A Po?tica do corpo no mito e na dan?a but?: por uma educa??o sens?vel

Tib?rcio, Larissa Kelly de Oliveira Marques 30 June 2005 (has links)
Made available in DSpace on 2014-12-17T14:35:50Z (GMT). No. of bitstreams: 1 LarissaKOMT.pdf: 1371897 bytes, checksum: 99dc7d93ffe08b68a3c07bbdf795ec6d (MD5) Previous issue date: 2005-06-30 / The thesis presents the body poetry and its inscribing in the myth and But? dance. The argumentation highlights the sensitive dimension present in these itineraries, as a possibility to operate the emergency of knowing inscribed in the body, bringing a kind of rationality that links the fragments, that allows the knowing to break through the barriers of disciplinary isolation, that abandons the certainties and goes through the ways of creation and that gives the body new space and time, featuring epistemological elements, ethical and esthetical, that can permit a sensitive education. All along the way, we comprehend by sensitive education, a education that considers the relinking of logical, analogical, symbolic and artistic knowledge and therefore reconsiders the own act of knowing as a continuous and inconcluded process. That sensitive education is also understood as retaking the body experience, its sensitive nature, as well as being meaningful to reading the world. It includes the body memory, its history and creativity, opening it to innovation, change, sense amplification and dialogue with other bodies and world, because it is within them. It is about an investigation of phenomenologic nature, that dialogues philosophy and art, pointing breakdowns of this reflection foe the body and education studies. We find it necessary to notice the body language, that allows one to think through movements, articulate a thought that is risen from articulations, guts and all the body. This incarnated reason starts the expressive body action, that makes us move to mean, communicate, inaugurate senses. Among these senses, we present a possibility of approach of the elements of But? dance teaching and physical education, as ways of sensitive education showings of body poetry / A tese apresenta a po?tica do corpo e sua inscri??o no mito e na dan?a but?. A argumenta??o ressalta a dimens?o sens?vel presente nesses itiner?rios, como possibilidade de operar a emerg?ncia dos saberes inscritos no corpo, instaurando um tipo de racionalidade que une os fragmentos, permite que os saberes atravessem as fronteiras do isolamento disciplinar, abandona as certezas e envereda pelos caminhos inusitados da cria??o, ressignificando o espa?o e o tempo do corpo, configurando elementos epistemol?gicos, ?ticos e est?ticos que possam favorecer uma educa??o sens?vel. Em todo o percurso, compreendemos por educa??o sens?vel uma educa??o que considera a religa??o dos conhecimentos l?gicos, anal?gicos, simb?licos, art?sticos, que considera a inscri??o corporal do conhecimento e como tal redimensiona o pr?prio ato de conhecer como um processo cont?nuo e inconcluso. Essa educa??o sens?vel ? tamb?m entendida como aquela que retoma a experi?ncia do corpo, sua natureza sens?vel, como significativa para a leitura do mundo. Inclui a mem?ria do corpo, a sua hist?ria, a sua criatividade, abrindo-se ? inova??o, ? mudan?a, ? amplifica??o dos sentidos e ao di?logo com os outros corpos e com o mundo, porque neles tamb?m se constitui. Trata-se de uma investiga??o de natureza fenomenol?gica, que dialoga filosofia e arte, apontando desdobramentos dessa reflex?o para os estudos do corpo e da educa??o. Consideramos necess?rio perceber a linguagem dos gestos, a qual possibilita pensar por movimentos, permite articular um pensamento que nasce das articula??es, das v?sceras, de todo o corpo. Essa raz?o encarnada aciona a a??o expressiva do corpo, que faz com que nos movamos para significar, para comunicar, para inaugurar sentidos. Dentre esses sentidos, apresentamos uma possibilidade de abordagem dos elementos da dan?a but? para o ensino da Dan?a e da Educa??o F?sica, como modos de educa??o sens?vel elucidativos da po?tica do corpo

– Ja men usch ... – Nä men exakt ... : En interaktionsanalys av samtida svenska ja men/nej men-konstruktioner / ‘Yes but ew ...’ ‘No but exactly ...’ : A conversation analysis of Swedish ‘ja men/nej men’ utterances.

Andersson, Susanna Birg January 2021 (has links)
I denna uppsats undersöks användningen av den etablerade och utbredda konstruktionen ja men/nej men, vars mångskiftande interaktionella betydelse i det svenska samtalsspråket inte tidigare har klarlagts i regelrätta studier. Utifrån en CA-baserad metodik och en modifierad modell av appraisalteorins dialogicitetssystem har ja men/nej men-konstruktionernas position, funktion, attityd och form i fyra dyadiska poddsamtal kategoriserats och analyserats. Kategoriseringen av konstruktionerna utgår ifrån – och kompletterar – tidigare internationella studier, och en övergripande beskrivning av de olika svenska ja men/nej men-konstruktionerna presenteras. I analysen av 137 fullföljda ja men/nej men-inledda yttranden, utkristalliserar sig nio funktioner för ja men/nej men, varav sju är sekvensreglerande och positionsoberoende. Av de sekvensreglerande funktionerna bidrar tre till att utvidga sekvensen (bekräftande, kompletterande, förhandlande), medan fyra inskränker och avslutar sekvensen (korrigerande, ifrågasättande, sammanfattande, skiftande). Utöver en sekvensreglerande funktion fyller de turinbäddade, men inte de turinledande, konstruktionerna även en av två praktiska funktioner (reparerande, anföringsmarkerande). Samtalsdeltagarna använder företrädesvis ja men/nej men-konstruktionerna turinledande i sekvensutvidgande yttranden. Ja men används något oftare än nej men, medan konstruktionen jo men ytterst sällan används. Ja men och nej men används såväl turinledande som turinbäddat, och i samtliga nio funktioner. Det kvantitativa resultatet indikerar att deltagarna i poddsamtalen tenderar att använda ja men med framhävande attityd i utvidgande funktioner, och nej men med nedtonande attityd i inskränkande funktioner. I den anföringsmarkerande funktionen ses ett samband mellan lexikal konstruktion och den handling som realiseras i det citerade yttrandet. En diakron studie av detta användande för att utröna om fenomenet är en rest från ett ursprungligt, prototypiskt bruk av konstruktionen föreslås som fortsatt forskning om ja men/nej men. / This thesis presents an examination of the well-establish and frequently used construction ja men/nej men (yes but/no but), which interactional significance in the Swedish language has not yet been investigated. By employing a CA-based method, and a modified model of the appraisal system of engagement, the position, interactional function, attitude, and form of the ja men/nej men-constructions in four dyadic podcasts has been categorized and analyzed. The categorization is based on – and contributes to – international studies, and a comprehensive description of the Swedish construction is presented. In the 137 analyzed ja men/nej men-initiated utterances, nine functions emerge of which seven regulate sequences, regardless of a turn-initiated or turn-embedded position. Three of these regulating functions expand the sequence (confirming, completing, negotiating), while four close it (correcting, challenging, concluding, shifting). The turn-embedded constructions also assume two additional practical functions (repairing, quotative marking). The participants primarily use the construction in sequence-expanding utterances and are more frequently using ja men than nej men, very rarely jo men. The result indicates that the participants tend to use an authoritative ja men to expand the sequence, and a hedging nej men to close the sequence. A correlation, although not significant, between lexical construction and function is seen in the quotative marking function, where the performed action in the quoted utterance seems to determine the lexical choice. A diachronic study of this usage, to investigate if this is a prototypical use, is one of the suggestions for future research of the usage of the Swedish ja men/nej men-construction.

Esperamos, a partir dessa observação, contribuir com as discussões sobre prática de ensino de Inglês com Fins Acadêmicos - IFA, uma vez que a proficiência insuficiente no idioma foi um dos problemas identificados em programas de mobilidade internacional. Tendo em vista a habilidade de produção escrita e utilizando a abordagem teórico-metodológica da Linguística de Corpus, elaboramos um corpus de aprendiz para análise - CA - utilizando 264 redações acadêmicas extraídas do Corpus Inglês para Fins Acadêmicos – CorIFA (DUTRA; QUEIROZ; ALVES, 2017). Esses textos foram escritos por alunos brasileiros universitários com proficiência B1 em língua inglesa. Também elaboramos um corpus de referência - CR - nos valendo das mesmas características do CA, com o objetivo de, após analisarmos os excertos referentes ao CR, realizarmos uma comparação entre a escrita de dois públicos não-nativos de língua inglesa. Para a elaboração do CR extraímos 31 redações acadêmicas escritas em língua inglesa por alunos não-nativos do Michigan Corpus of Upper-Level Student Papers - MICUSP. Nossa fundamentação teórica conta como base os descritores de competência de produção escrita do Quadro Europeu Comum de Referência para Línguas - QECR (2001) para descrever o uso de conjunções em redações acadêmicas de alunos no nível B1 de proficiência de língua inglesa. Para descrever as conjunções but e however, utilizamos as gramáticas com base em corpus Longman de Biber et al (1999) e Cambridge (CARTER; MCCARTHY, 2006), gramáticas de ensino de língua inglesa Practical English Usage (SWAN, 2005), The Grammar Book (CELCE-MURCIA; LARSEN FREEMAN, 1999), a Gramática da Língua Inglesa de Watkins e Porter (2006) e os dicionários online de Cambridge e Wordreference. Por meio desse material, descrevemos a razão pela qual but e however são elementos gramaticais expressivos e relevantes para a escrita de redações acadêmicas em língua inglesa. A extração dos dados foi realizada por meio da ferramenta computacional AntConc  (ANTHONY, 2011), que gera linhas de concordância e as agrupa de acordo com o elemento do texto que estamos buscando. Após a extração e análise dos dados de ambos os corpora, comparamos o uso das conjunções em início de orações para descrever as semelhanças ou diferenças de escrita entre os dois grupos de estudantes não-nativos. Dados encontrados em nosso corpus de análise CorIFA demonstraram que uma parcela dos alunos universitários brasileiros utiliza as conjunções de forma equivocada, segundo apontam as gramáticas apresentadas em nossa fundamentação teórica. Ainda, comparados aos dados extraídos de nosso corpus de referência, esses números mostram que os alunos brasileiros possuem condições de escrita aquém dos alunos que escreveram os textos extraídos do corpus MICUSP, apontando para a necessidade de maior aprofundamento de estudo de Inglês com Fins Acadêmicos nas universidades brasileiras. / The objective of this present research is to describe the use of the conjunctions, “but” and “however”, in academic essays written in English by Brazilian university students. From this observation, we expect to contribute to the discussions on the practice of teaching English for Academic Purposes - EAP, once insufficient language proficiency was one of the problems identified in international mobility programs. In view of a written production skill and based on theoretical backgrounds of Corpus Linguistics, we have developed a corpus of English learner for analysis - CA – formed by 264 academic essays extracted from the Corpus Inglês para Fins Acadêmicos – CorIFA (DUTRA; QUEIROZ; ALVES, 2017). These texts were written by Brazilian university students with B1 proficiency in English. We also built a corpus of reference - CR - using the same characteristics of the CA, and, after analyzing the excerpts referring to the CR, we compared the writing of these two groups of non-native English-speaking learners. For the drafting of the CR we extracted 31 academic essays written in English by non-native students from the Michigan Corpus of Upper-Level Student Papers - MICUSP. Our theoretical basis relies on the written production ability descriptors of the Common Reference Framework for Languages (2001) to describe the use of conjunctions in academic writing B1 proficiency level. In order to describe the conjunctions “but” and “however”, we use the corpus based grammars Longman by Biber et al (1999) and Cambridge (CARTER; MCCARTHY, 2006), English-language grammars Practical English Usage (SWAN, 2005), The Grammar Book (CELCE-MURCIA; LARSEN FREEMAN, 1999), The English Grammar by Watkins and Porter (2006) and the Cambridge and Wordreference online dictionaries. Through this material, we describe the reason why we consider “but” and “however” expressive grammatical elements and believe in the importance of the proper use of these conjunctions in academic essays. Data extraction was performed using the software AntConc  (ANTHONY, 2001), which generates lines according to the word we are looking for. After extracting and analyzing data from both corpora, we compared the use of conjunctions in the beginning of the sentences in order to describe the similarities or differences in writing between the two non-native students. Data found in our analysis from CorIFA have demonstrated that a portion of Brazilian university students uses conjunctions in a wrong way, according to the grammars presented in our theoretical basis. Also, compared to the data extracted from our CR, numbers show that Brazilian students have written conditions below the students who wrote the texts extracted from the MICUSP corpus, pointing to the need for a more in-depth study of English for Academic Purposes in Brazilian universities.

Estruturas finitas de repetição verbal em português brasileiro / Finite structures with verbal repetition in Brazilian Portuguese

Santos, Leticia Evelyn Leite 20 September 2018 (has links)
O objetivo desta dissertação é descrever o comportamento de estruturas com repetição verbal em português brasileiro que apresentam características específicas diferentes de outras construções com repetição verbal já estudas no português brasileiro (Bastos 2001/ Bastos-Gee 2009) e no português europeu (Martins 2007). As estruturas em questão são iniciadas com que, sendo que em cada uma delas o constituinte encabeçado por que aparece em posições diferentes na sentença: quando o que está no primeiro bloco, nomeio a estrutura de que-reportativo; quando o que está no segundo bloco, nomeio a estrutura de que-adversativo. Essas construções apresentam similaridades, como a necessidade dos constituintes verbais serem idênticos, mas também apresentam muitas diferenças entre si além da posição do que: ter necessidade de repetir um antecedente discursivo obrigatoriamente, que só ocorre com que-reportativo, e a presença de uma sentença coordenada adversativa implícita, o efeito-mas (Bastos 2001/Bastos-Gee 2009), que também só ocorre com que-reportativo. Através da comparação com outras estruturas de repetição verbal já estudadas no português, mostro que as construções analisadas nesta dissertação possuem comportamentos diferenciados e envolvem tópicos diferentes, a saber, a estrutura com que-reportativo envolve tópico conversacional, enquanto a estrutura com que-adversativo envolve tópico contrastivo. / The goal of this dissertation is to describe the behavior of finite structures with verbal repetition in Brazilian Portuguese, which present different specific characteristics from other verbal repetition constructions previously studied in Brazilian Portuguese (Bastos 2001/ Bastos-Gee 2009) and in European Portuguese (Martins 2007). The structures in question start with que that, but the constituents headed by que occupy different positions in each structure: when que is in the first block of the sentence, I call the structure reportative-que; when que is in the second block of the sentence, I call the structure adversative-que. These structures present similarities, such as the requirement of identical verbal constituents, but also exhibit many differences besides the position where que appears: the requirement to repeat the previous discourse and the presence of an implicit adversative clause - the but-effect (Bastos 2001/ Bastos-Gee 2009) -, for instance, only happens with reportative-que. Through the comparison with other verbal repetition structures already studied in Portuguese, I demonstrate the structures analyzed in this dissertation have a differentiated behavior. I also demonstrate that they are composed by different topics, namely, reportative-que has a conversational topic, while adversative-que has a contrastive topic.

“Learning is not always fun, but it is fine” Effects of Rationale Generation on Autonomous Motivation and Learning in Uninteresting but Required Academic Activities

Cong Wang (7474124) 17 October 2019 (has links)
<p>This dissertation aimed to study the effects of rationale generation on college students’ autonomous motivation. Specific research questions were: (1) to investigate the relations among rationale generation, motivation, and learning through the lens of SDT; (2) to examine the causal effects of rationale generation on autonomous motivation and learning performance; and (3) to understand students’ perceptions of successful motivation strategies during uninteresting but required academic activity. An explanatory sequential mixed method design was used to answer these questions. </p>

L'association entre libéralisme économique et état social. Une analyse des schèmes de justification de l'économie sociale au XIXème et XXème siècle

Fretel, Anne 09 September 2008 (has links) (PDF)
Cette thèse cherche à montrer comment la notion d'association en France, dans les réponses qu'elle a apportées à la question sociale au XIXe et XXe siècle, s'est trouvée polarisée par les deux schèmes de justification dominants que sont le libéralisme économique et l'Etat social. Au XIXe siècle, on montre comment la notion d'association a été majoritairement pensée en articulation avec le libéralisme économique et au XXe siècle comment elle a été pensée en lien avec l'Etat social. Pour autant, pour chacune de ces périodes, l'association ne s'est pas trouvée rabattue sur un de ces schèmes dominants faisant ainsi preuve d'une capacité de questionnement et d'innovation. Pour résumer ce lien complexe que l'association entretient avec le libéralisme économique et l'Etat social, le terme de polarisation a été choisi signifiant par là que l'association n'est jamais rabattue sur un schème dominant mais qu'elle est seulement attirée et garde une part d'autonomie. Ainsi, si l'association s'est inscrite dans les logiques dominantes de réponse à la question sociale, cela ne l'a pas empêchée d'en pointer à chaque fois des limites. Au XIXe siècle, elle complète le schéma libéral en instituant un cadre moral qui guide les actions individuelles vers l'intérêt général ; au XXe, elle cherche à renforcer la dimension démocratique de l'Etat en proposant des réponses spécifiques aux problèmes sociaux. Centrée sur une analyse de discours et un choix qualitatif d'auteurs, la notion d'association telle qu'elle ressort de ce travail, est à prendre dans un sens étendu. Elle illustre avant tout une forme d'organisation sociale cherchant à assurer la cohésion sociale.

Evaluation qualitative et quantitative de scénarios d'évolution de l'organisation et de son système d'information

Papadacci Stephanopoli, Emmanuel 30 May 2008 (has links) (PDF)
L'arbitrage est une étape essentielle du processus de gestion de l'évolution d'une organisation et de son système d'information, en particulier lors des études d'Urbanisme du SI. Le but de la méthode NENO est de fournir une assistance aux décideurs lors de la réalisation d'arbitrages dans ce contexte. L'arbitrage induit un processus de priorisation qui s'applique à de très grands ensembles d'exigences. Les approches de priorisation classiques en « requirement engineering » sont toutes confrontées à un problème de scalabilité lié au fait qu'elles considèrent les exigences individuellement. La multiplicité des alternatives et des critères de décisions présentés aux décideurs ne permet pas l'application des techniques classiques.<br />La méthode NENO consiste au contraire à regrouper les exigences (représentées sous la forme de buts fonctionnels) de manière à offrir qu'un nombre restreint d'alternatives aux décideurs. Ces regroupements effectués sont conformes aux dépendances entre buts, et s'exercent à différents niveaux d'abstraction. Conformément à la pratique au sein des organisations, les critères de décisions sont représentés sous la forme d'objectifs métiers que celles-ci doivent atteindre à moyen et long terme. Les buts sont individuellement évalués par des experts métier quant à leur faculté à satisfaire tout ou partie des objectifs métiers. Le recueil des évaluations est participatif, progressif et qualitatif. Un ensemble d'algorithmes permet de transposer et agréger les évaluations qualitatives en résultats quantitatifs dans le but de présenter les résultats sous la forme de priorités.

Une Approche Méthodologique pour la Modélisation Intentionnelle des Services et leur Opérationnalisation

Kaabi, Rim Samia 13 February 2007 (has links) (PDF)
Le paradigme SOA est devenu un standard pour la conception technique et le développement d'applications logicielles. Malgré tous les avantages qu'il apporte notamment dans la résolution des problèmes d'hétérogénéité, les solutions associées à ce paradigme sont dédiées aux développeurs et restent difficiles à transposer au monde de l'entreprise. L'hypothèse de cette thèse est que pour tirer le meilleur profit du paradigme SOA, il est nécessaire d'adopter une position dan laquelle les services sont décrits en termes de besoins qu'ils permettent de satisfaire, c'est a dire par les buts organisationnels a satisfaire. Nous qualifions ces services d'intentionnels. La publication, la recherche et la composition de ces services se fait sur la base de ces descriptions intentionnelles. De cette façon, on parle d'un portage de SOA au niveau intentionnel que nous qualifions de ISOA.<br />La solution proposée dans cette thèse a conduit aux résultats suivants :<br />− Un modèle de représentation des services intentionnels qui intègre la variabilité et la réflexivité : le modèle MiS (Modèle Intentionnel de Services),<br />− Une démarche pour identifier les services intentionnels à partir des besoins des utilisateurs,<br />− Un modèle de représentation des services opérationnels : le modèle MoS (Modèle Opérationnel de Services),<br />− Une démarche pour dériver les services opérationnels à partir des services intentionnels,<br />− Une architecture à agents permettant l'exécution intentionnelle des services.

Modélisation intentionnelle et annotation sémantique pour la réutilisation de services métiers PASiS: Publishing And Searching of Intentional Services

Aljoumaa, Kadan 20 October 2011 (has links) (PDF)
Ce travail est une continuation des travaux antérieurs sur l'architecture iSOA et le modèle de service intentionnel MiS. Il s'agit de rendre accessible les services proposés par MiS en complétant la plateforme iSOA avec des mécanismes pour la publication et la recherche de services intentionnels dans un annuaire étendu. Ces mécanismes feront appel aux techniques des services web sémantiques et à la modélisation de la connaissance sous forme d'ontologies. Le propos de ce travail de recherche porte sur les lacunes identifiées sur le processus de publication d'un service, l'approche de recherche adéquate pour sélectionner les services intentionnels les plus adaptés aux besoins de l'utilisateur et la structure du descripteur d'un service intentionnel à publier dans l'annuaire. Nous proposons l'approche PASiS (Publishing And Searching intentional Services). Dans cette approche, l'input d'un fournisseur lors de la publication d'un service s'exprime en termes métier sous forme de buts. Nous proposons un processus de guidage de publication, pour d'une part, aider le concepteur dans cette tâche, et d'autre part garantir la complétude de la description d'un service publié. Ce processus utilise les ontologies pour capturer la sémantique du descripteur de service intentionnel. Ces ontologies sont : iSOnto (ontologie technique de services intentionnels), vOnto (ontologie générique des verbes) et pOnto (ontologie de domaine des produits). Enfin, notre approche prend en compte au niveau du descripteur et du processus de publication, les agrégations de services intentionnels telles que définies dans le modèle de MiS. Dans PASiS, l'utilisateur exprime ses besoins sous forme de but. Grâce à un modèle du processus de recherche et d'interrogation, nous proposons le guidage pour d'une part, aider l'utilisateur à tirer profit de toutes les possibilités qu'offre le modèle de requête, et d'autre part pour l'accompagner dans sa recherche et l'aider à trouver ce qu'il souhaite. L'appariement se fait entre les concepts associés à la requête et ceux associés aux descripteurs de services en utilisant une fonction de calcul de distance sémantique qui exploite les liens sémantiques (généralisation, spécialisation). En exploitant les concepts de services intentionnels agrégés, l'utilisateur peut parcourir l'arborescence de services composites et à variation et explorer ainsi l'espace des services intentionnels disponibles. Enfin, l'usage d'ontologies est la base d'un processus de reformulation intelligente de la requête de l'utilisateur. L'utilisation de l'ontologie générique des verbes et des liens sémantiques entre les verbes et les noms propre, nous pouvons raisonner sur la signification d'un but et d'introduire ainsi intelligence et guidage dans les processus de publication et de recherche de service. Ce travail est consacré également, à la spécification et à l'implémentation du descripteur intentionnel de service où l'annotation est utilisée comme une technique d'extension sémantique vers les trois ontologies : iSOnto, vOnto et pOnto. Dans ce travail, nous proposons d'étendre le langage SAWSDL pour décrire les services intentionnels. Cette extension vient combler un manque au niveau de la spécification de la nature de l'annotation sémantique dans SAWSDL. Pour cette raison, nous allons utiliser l'ontologie iSOnto pour expliciter non seulement les concepts d'un domaine mais également la nature de ces concepts. Enfin, l'approche proposée est illustrée au moyen d'une étude de cas d'application. A la lumière de ce cas d'étude, nous avons montré que les hypothèses de recherche sont valides.
