    Cet article prĂ©sente les premiers rĂ©sultats d’une recherche s’intĂ©ressant Ă  l’articulation entre imitation et invention dans l’écriture chez les jeunes scripteurs. L’étude s’attache Ă  observer les modes de rĂ©cupĂ©ration de ressources textuelles fournies par les conditions de production. L’expĂ©rimentation a Ă©tĂ© conçue pour observer l’appropriation d’un genre. Des dispositifs didactiques ont Ă©tĂ© proposĂ©s Ă  plusieurs classes de fin d’école primaire française, Ă  partir de textes littĂ©raires issus de la robinsonnade mis Ă  disposition soit simultanĂ©ment Ă  l’acte d’écriture soit lors d’une seconde Ă©criture. L’étude montre comment les Ă©lĂšves ont recours Ă  deux procĂ©dĂ©s contrastĂ©s : le rĂ©investissement du lexique et la reformulation. Les donnĂ©es recueillies mettent en Ă©vidence la reprise attendue de mots caractĂ©ristiques du genre, et rĂ©vĂšlent l’ingĂ©niositĂ© des scripteurs pour restructurer des matĂ©riaux langagiers. Certaines stratĂ©gies tĂ©moignent des difficultĂ©s rencontrĂ©es par les Ă©lĂšves qui ont eu Ă  interprĂ©ter le lexique littĂ©raire puis Ă  le transfĂ©rer dans leur propre rĂ©cit. Des modes de reformulation diffĂ©rents coexistent dont on peut offrir une premiĂšre catĂ©gorisation en fonction d’une appropriation plus ou moins rĂ©ussie du genre considĂ©rĂ©.ABSTRACT This article presents the first results of a research on the relationship between imitation and invention in the writing process amongst young writers. The study aims at observing the recovery modes of textual resources provided by the circumstances of production. The experiment was designed to observe the acquisition of a genre. Teaching tools have been proposed to several French classes of Primary school. They were literary texts derived from Robinson-type stories, that were available either immediately when writing, or during the time of a secondary writing. The research shows how students use two contrasting methods, the reinvestment of the lexicon as well as rephrasing. The data highlight the expected reuse of characteristic words of the genre, and reveal the ingenuity of writers in the restructuring of language materials. Some strategies reflect the difficulties faced by the pupils who have had to interpret the literary lexicon and then to transfer it into their own story production. Different rephrasing modes coexist that we can categorize according to a more or less successful appropriation of the genre considered

    Corticomotor control of the genioglossus in awake OSAS patients: a transcranial magnetic stimulation study

    Get PDF
    <p>Abstract</p> <p>Background</p> <p>Upper airway collapse does not occur during wake in obstructive sleep apnea patients. This points to wake-related compensatory mechanisms, and possibly to a modified corticomotor control of upper airway dilator muscles. The objectives of the study were to characterize the responsiveness of the genioglossus to transcranial magnetic stimulation during respiratory and non-respiratory facilitatory maneuvers in obstructive sleep apnea patients, and to compare it to the responsiveness of the diaphragm, with reference to normal controls.</p> <p>Methods</p> <p>Motor evoked potentials of the genioglossus and of the diaphragm, with the corresponding motor thresholds, were recorded in response to transcranial magnetic stimulation applied during expiration, inspiration and during maximal tongue protraction in 13 sleep apnea patients and 8 normal controls.</p> <p>Main Results</p> <p>In the sleep apnea patients: 1) combined genioglossus and diaphragm responses occurred more frequently than in controls (<it>P </it>< 0.0001); 2) the amplitude of the genioglossus response increased during inspiratory maneuvers (not observed in controls); 3) the latency of the genioglossus response decreased during tongue protraction (not observed in controls). A significant negative correlation was found between the latency of the genioglossus response and the apnea-hypopnea index; 4) the difference in diaphragm and genioglossus cortico-motor responses during tongue protraction and inspiratory loading differed between sleep apnea and controls.</p> <p>Conclusion</p> <p>Sleep apnea patients and control subjects differ in the response pattern of the genioglossus and of the diaphragm to facilitatory maneuvers, some of the differences being related to the frequency of sleep-related events.</p

    Cet article porte sur la maniĂšre dont des scripteurs dĂ©butants emploient et rĂ©investissent des matĂ©riaux linguistiques issus Ă  la fois d’un texte qu’ils ont eux-mĂȘmes produit et d’un corpus de textes littĂ©raires qui leur a Ă©tĂ© fourni. Il s’intĂ©resse aux modes de rĂ©cupĂ©ration de ces matĂ©riaux et Ă  la façon dont ceux-ci s’intĂšgrent au texte nouvellement produit. Les observations menĂ©es pour identifier et caractĂ©riser ces traitements ont portĂ© sur la production de rĂ©cits ou de suites de rĂ©cits relevant du genre de la robinsonnade par 48 élĂšves de fin d’école primaire au cours de deux phrases d’écriture. Ces Ă©lĂšves ont eu Ă  leur disposition un corpus d’extraits littĂ©raires de robinsonnades lors de la deuxiĂšme phase d’écriture. L’analyse des donnĂ©es mĂšne vers deux constats. D’une part, on note que la rĂ©cupĂ©ration des Ă©lĂ©ments provenant des textes sources s’effectue selon deux formes diffĂ©rentes de fidĂ©litĂ© Ă  ces textes, l’une privilĂ©giant le prĂ©lĂšvement d’élĂ©ments, l’autre la restitution sĂ©mantique. D’autre part, on observe deux tendances contrastĂ©es lors de la rĂ©Ă©criture, l’une consistant Ă  maintenir le systĂšme dĂ©ployĂ© en premiĂšre version et Ă  accorder la prĂ©pondĂ©rance aux matĂ©riaux issus de cette premiĂšre phase, l’autre dans laquelle les actes dĂ©cisionnels sont largement dĂ©terminĂ©s par le substrat littĂ©raire fourni. Ces tendances prĂ©sentent elles-mĂȘmes des variantes qui sont marquĂ©es par l’influence du dĂ©jĂ -lĂ  culturel dont dispose l’apprenant. Ces constats fournissent des Ă©lĂ©ments pour caractĂ©riser des modes d’écriture et devraient ouvrir vers des pistes didactiques.This article examines how novice scriptwriters use and reinvest linguistic elements from both a text that they had previously written themselves and a corpus of literary texts that had been provided to them. In particular, this article focuses on how such elements are re-exploited to fit into a newly generated text. The observations carried out to identify and characterise these processes derive from the production of narratives and of successions of stories of the “robinsonade” genre by 48 pupils at the end of primary school following a two-phase process. These pupils were provided with a body of “robinsonade” extracts during the second writing phase. The data analysis leads to two conclusions. First, the recycling of elements from the source texts stems from two different forms of loyalty towards the said texts: one favouring the removal of elements, the other favouring semantic restitution. Secondly, two contrasting trends are observed when it comes to rewriting. The first one consists in maintaining the system originally used to produce the first version and to favour elements used during this first phase. In the second one, decision-making is largely determined by the literary substrate that is provided. Variants exist amongst these tendencies and they are influenced by the “already-there” culture of the one who learns. The above findings provide material to characterise ways of writing and should help open new didactic approaches

    A prĂĄtica da redação desde o inĂ­cio da escolaridade tem espaço na França oficialmente a partir de 1880. Contudo, seu ensino nĂŁo se impĂŽs sem dificuldades. Na verdade, os programas dĂŁo diretrizes Ă s vezes contraditĂłrias e os procedimentos utilizados pelos professores se revelam parcialmente ineficazes, assim como os resultados esperados pela Instituição sĂŁo muito fracos. Na batalha das ideias que conduzem a uma evolução dos textos regulamentais, mas tambĂ©m Ă s prĂĄticas divergentes, qual a função dos livros didĂĄticos? Nossa contribuição se propĂ”e a alimentar a reflexĂŁo sobre as funçÔes e o lugar dos livros didĂĄticos nas salas do final da escola primĂĄria (curso mĂ©dio) ao longo do perĂ­odo que se estende do pĂłs-guerra atĂ© o “Plano de renovação do ensino francĂȘs” (1971). Essas trĂȘs obras (1947, 1956, 1969) revelam, atravĂ©s das respectivas interpretaçÔes dos programas, as influĂȘncias sociais e ideolĂłgicas constrantantes. Eles informam sobre as interrogaçÔes que atravessam a comunidade educativa sobre o status dos saberes, os modos de ensino e de aprendizagem, bem como as finalidades da escola.The policy consisting in teaching structured writing from the very beginning of school has been officially established in France in the early 1880s. However, this policy did not prevail without difficulties. Indeed, official programs have at times given contradictory guidelines and the procedures established by the teachers have proven partly ineffective. As a consequence, results have been considered insufficient by the Institution. What was the role of textbooks in the debate that made official instructions evolve while generating divergent practices in the field? Our contribution aims at fostering ideas on the institutional function and on the prac-tical role of textbooks in the teaching of writing. To this end, we compare three textbooks in use in primary school late classes during the aftermath of World War II and until the advent of the “Renovation Plan for the Teaching of French” (1971). These three books (1947, 1956, 1969) reveal contrasting social and ideological influences, through different interpretations of the official progams. They provide information on the questioning that animate the educational community regarding the status of knowledges, teaching methods, learning dynamics, and the finalities of school.La pratique de la rĂ©daction dĂšs le dĂ©but de la scolaritĂ© se met en place en France officiellement Ă  partir de 1880. Toutefois, son enseignement ne va pas s’imposer sans difficultĂ©. En effet, les programmes donnent des directives parfois contradic-toires et les procĂ©dures mises en place par les enseignants se rĂ©vĂšlent partiellement inefficaces si bien que les rĂ©sultats sont estimĂ©s trop faibles par l’Institution. Dans la bataille des idĂ©es qui conduit Ă  une Ă©volution des textes rĂ©glementaires mais aussi Ă  des pratiques divergentes, quel a Ă©tĂ© le rĂŽle des manuels ? Notre contribution se propose d’alimenter la rĂ©flexion sur les fonctions et la place des manuels dans l’enseignement de la rĂ©daction Ă  travers la comparaison de trois manuels scolaires Ă  usage dans les classes de fin d’école primaire (cours moyen) au cours de la pĂ©riode allant de l’aprĂšs-guerre jusqu’au « Plan de rĂ©novation de l’enseignement du français » (1971). Ces trois ouvrages (1947, 1956, 1969) rĂ©vĂšlent, Ă  travers leurs interprĂ©tations des programmes, des influences sociales et idĂ©ologiques contrastĂ©es. Ils renseignent sur les interrogations qui traversent la communautĂ© Ă©ducative sur le statut des savoirs, les modes d’enseignement et d’apprentissage et les finalitĂ©s de l’école

    Diaphragm pacing failure secondary to deteriorated chest wall mechanics: When a good diaphragm does not suffice to take a good breath in

    AbstractDiaphragm pacing allows certain quadriplegic patients to be weaned from mechanical ventilation. Pacing failure can result from device dysfunction, neurotransmission failure, or degraded lung mechanics (such as atelectasis). We report two cases where progressive pacing failure was attributed to deteriorated chest wall mechanics. The first patient suffered from cervical spinal cord injury at age 45, was implanted with a phrenic stimulator (intrathoracic), successfully weaned from ventilation, and permanently paced for 7 years. Pacing effectiveness then slowly declined, finally attributed to rib cage stiffening due to ankylosing spondylitis. The second patient became quadriplegic after meningitis at age 15, was implanted with a phrenic stimulator (intradiaphragmatic) and weaned. After a year hypoventilation developed without obvious cause. In relationship with complex endocrine disorders, the patient had gained 31 kg. Pacing failure was attributed to excessive mechanical inspiratory load. Rib cage mechanics abnormalities should be listed among causes of diaphragm pacing failure and it should be kept in mind that a “good diaphragm” is not sufficient to produce a “good inspiration”
