La recherche présentée ici porte sur le repérage et l’analyse, en situation de formation, des difficultés de lecture rencontrées par les élèves réputés « faibles lecteurs » au début du collège dans le domaine de la compréhension/interprétation des textes littéraires. Plus précisément, elle vise l’expérimentation d’outils de formation du lecteur qui puissent parallèlement aider l’enseignant de français à établir un diagnostic. Ces outils consistent en des tâches globales et réflexives, par lesquelles l’élève est amené à la fois à construire et manifester sa compréhension d’un texte et à procéder à un retour réflexif sur sa propre activité de lecteur. Deux tâches de ce type ont pu être expérimentées : la production d’une note critique de lecture d’une part, la rédaction d’une scène de lecture dont l’élève est le héros d’autre part. L’article est largement consacré à la description de l’expérimentation menée ainsi qu’à l’analyse des résultats. Il débouche sur une comparaison avec le questionnaire de lecture qui vise à analyser les spécificités et les effets de différents types de tâches d’exploitation et d’évaluation de la lecture. Enfin, cette recherche a permis d’esquisser une typologie de quelques difficultés de lecture que l’enseignant pourra convoquer afin d’analyser les écrits produits par ses élèves au moyen des outils proposés.

The one day clinic possesses its own structure and organisation; patient management is also specific. Preoperative visit and assessment are programmed at least 48 hours before anesthesia. Preoperative examinations and choice of anesthetic technique (sedation associated with local anesthesia or not, general anesthesia, locoregional anesthesia, or hypnosedation) are discussed and determined depending upon medical history, clinical examination, and type of procedure. General recommandations, instructions about fasting, interruption of some therapies, and introduction of new medication(s) are explained orally and also provided in a written document. New anesthetics and analgesics allow quick awakening and recovery of vital functions, and subsequently rapid hospital discharge. Prevention and aggressive treatment of postoperative nausea and vomiting are also a major concern in our anesthesic management of ambulatory patient. [less ▲]

This paper presents a methodology of damage analysis at elevated temperature using the finite element method. Both the model and the methodology to identify parameters are summarized. The mechanical properties are established using compression tests at elevated temperature. An elasto-visco-plastic model depending on temperature is identified. A metallographic analysis is used to determine the original size and morphology of the austenitic grains. The experimental damage analyses consist in acoustic tests in order to determine the apparition of the first crack during compression. Finite element simulations of these experiments allow the determination of the damage parameters using a reverse method. [less ▲]

Après avoir rappelé sa définition, nous illustrons et détaillons les caractéristiques de cette production graphique, intermédiaire entre l'esquisse conceptuelle et le plan net. Nous montrons ensuite l'intérêt à considérer cette production graphique spécifique comme un mode d'interface privilégié avec le monde numérique en conception. Le logiciel prototype IC&C - Interaction par Croquis de Composition - est ensuite succinctement décrit pour démontrer l'innovation et la pertinence de ce concept et montrer son niveau d'opérabilité actuel en DAO architecturale.

Uncertainty is one of the contingency factors examined by previous studies on management control systems design. However, its role remains unclear. This paper presents the results of an empirical study, which shows that perceived uncertainty more intervenes to explain the of informal management control mechanisms and the interactive use of formal management control systems than to explain the nature of the latter.

Research related to the prevention of business failure is surveyed in this paper. More specifically, the evolution of the accounting literature on business failure from a predictive to a preventive perspective is explained. After a clarification of the concept of business failure prevention, the main features of representative studies are presented and analysed. These studies are compared in terms of dynamics of the results proposed, of failure stage(s) studied, of conceptual approach privileged, of research object and of methodology used to obtain results. A typology of the research on business failure prevention is then proposed on the basis of two pertinent differentiating criteria: the dynamics of the contributions and the failure stage(s) taken into consideration. This paper finally stresses current limitations of business failure prevention literature, particularly the need for a consensus on how and why firms fail and the lack of investigation about typical failure profiles and paths. Potentialities for future progress in the field are discussed at the end of the paper. [less ▲]

The usual life cycle of Alpine newts comprises an aquatic larval stage and a terrestrial juvenile and adult stage. However, some populations differ from this pattern in exhibiting facultative paedomorphosis where some individuals reach sexual maturity while retaining larval traits such as gills and gill slits. While paedomorphic newts can, in some circumstances, initiate metamorphosis, once a newt has commenced metamorphosis, the state is irreversible. Because the frequency of this switching from one morph to the other has never been quantified in the wild, we attempted to estimate switching rate and survival by carrying out a 3-year monitoring survey of a population inhabiting an alpine lake. While morph switching did occur in this population, it involved a relatively low proportion of the paedomorphs (approx. 12%), suggesting that metamorphosis is not favoured in the study population. The hypothesis of paedomorphic advantage was not supported since neither survival nor body condition differed between morphs. The ontogenetic pathway of wild Alpine newts is thus characterised by two forks in the developmental pathway. The first occurs during the larval stage (metamorphosis vs. paedomorphosis), and the second occurs in paedomorphic adults (switching for metamorphosis vs. continuation of the paedomorphic lifestyle). Such a two-level decision process may allow individuals to cope with environmental uncertainty. [less ▲]

The acute toxicity of essential oils from the whole fruit (EF) or from the fibres of the fruit (FF) of the local aromatic plants Xylopiα αethiopicα Dunal (Annonaceae) collected in north Cameroon was evaluated on Sitophilus zeαmαis adults. A concentration of 1 ml of essential oil per 100 g of maize seeds was tested to determine weevil mortality after 24 h of exposure. Under these conditions, the essential oil derived from both EF and FF of X. αethiopicα led to 100% mortality. In a second step, proportions of active compounds present in the oil of both EF and FF of X. αethiopicα were quantified. The toxicity of the four main compounds was tested against S. zeαmαis: α-pinene, β-pinene, -3-carene and terpinen-4-ol according to their proportion in the essential oil of the concerned plant part. β-pinene and terpinen-4-ol were responsible for 50% of the mortality at the proportion found in EF and FF essential oils respectively. When mixed, a synergic effect of the compounds was observed that restored the mortality percentage observed for the crude oil. It appears that X. αethiopicα essential oil could be a potential source of natural and low-cost insecticide to control storage pests. [less ▲]
