For years, original free-surface flow solvers have been developed and continuously improved by the Laboratory of Applied Hydrodynamics and Hydraulic Constructions (HACH) at the University of Liège. The resulting fully integrated WOLF computation package allows engineers to accurately study a very wide range of various free surface flows, from hydrological runoff (WOLF HYDRO) and river propagation (WOLF 1D) to extreme erosive flows on realistic mobile topography (WOLF 2D), such as gradual dam breaching processes. All the finite volume models, process oriented, use efficient and original numerical methods to solve free surface flows equations. Each code handles general multiblock meshes, dealing with natural topography, dry and wet cells and mobile bed simultaneously, for any unsteady situation with mixed regimes and moving hydraulic jumps. The interactive and unique user-interface, with high performance pre- and post-processing, allows monitoring 3-D large-scale runs graphically while they proceed, as well as generating 3D videos. In addition, powerful optimisation capabilities based on the Genetic Algorithms technique (WOLF AG) are implemented within WOLF, interconnecting all the package components. An efficient tool is thus available to calibrate physical parameters in any of the models and to manage any problem of optimisation with the different solvers. In this paper, the numerical optimisation process of the system of hydroelectric power stations installed on a 60 km long section of the rivers Amblève and Warche in Belgium is presented in detail. The river network is modelled in quasi-2D using real natural topographic data on almost 1,100 finite volumes. In a first step, the hydrological balance is closed using the solver WOLF HYDRO. Roughness coefficients are calibrated from water level and discharge field measurements. Secondly, the hydroelectric production is maximised by an automatic calibration of the parameters of the hydrograph released in the network at the upstream dam. This approach leads to a substantial gain in hydroelectric production, brings significant financial benefits and deals with all management and security criteria of the river network. [less ▲]

A l’origine de la professionnalisation de l’enseignement et de l’apprentissage, le courant de l’évaluation de classe (en anglais « classroom assessment ») est une composante d’un autre courant, celui de la recherche en classe, né aux Etats-Unis au début des années 1990. Il a pour but d’aider les enseignants du supérieur à mieux comprendre ce que les étudiants apprennent à leur cours et avec quelle qualité ils apprennent. La recherche en classe pousse les enseignants à tenter de mieux comprendre les processus d’apprentissage en oeuvre chez leurs étudiants et à isoler les facteurs sur lesquels leur enseignement peut avoir une influence.

Le but de cette communication est d’introduire un modèle clinique de diagnostic de situations de souffrance relationnelles au travail, y compris le harcèlement moral. Ce modèle vise à offrir aux professionnels une grille d’analyse utilisable dans le cadre d’entretiens avec des personnes se sentant victimes de harcèlement moral ou de violence au travail. Les corpus théoriques de référence sont principalement la littérature clinique et organisationnelle sur le harcèlement moral, celle sur la violence au travail, l’analyse systémique des phénomènes d’abus et de conflit en organisation et le coping en situation de stress. Ce modèle a été construit à partir d’un programme de recherche-action comprenant d’une part la rencontre de personnes s’estimant victimes de harcèlement moral, et d’autre part l'analyse d’interventions en organisations à des fins de gestion de conflits. Une méthode d’analyse de cas a été appliquée afin d’identifier dans les témoignages de victimes quels étaient les éléments déterminants d’une situation de harcèlement moral. Plus précisément, nous avons inventorié pour chacun des entretiens les comportements de harcèlement décrits par les personnes, les conséquences qu’elles rapportaient, leurs stratégies pour y faire face, la durée et le contexte organisationnel de la situation. Les interventions en organisations ont été également analysées afin d’investiguer la manière dont les personnes définissaient et décrivaient les situations de souffrance relationnelles au travail. Dans ce cas, c’est l’ensemble des protagonistes que nous avons interrogés sur les sujets étudiés dans les analyses de cas. Ce modèle propose de distinguer cinq phénomènes : la souffrance aiguë au travail, la violence au travail, l’hyperconflit au travail, l’abus sur le lieu de travail et le harcèlement moral. Afin de mener le diagnostic, des critères discriminants sont proposés : l’observation des conséquences sur le bien-être, l’analyse des comportements hostiles, l’observation des dynamiques cognitives entre les parties, la complémentarité de la relation et l’échec du coping.

The aim of this study was to analyze the absence of adjustment of insulin doses in type 1 diabetic patients with poorly controlled diabetes. Twenty-eight patients (HbA1c higher than 8.5% during the last 6 months, performing at least three capillary blood glucose determinations per day), completed a questionnaire on the degree of confidence in their own knowledge, the nature of their health beliefs, their fear of hypoglycemia, their own appreciation on how they adjust their insulin doses (subjective score). An analysis of their diabetes logbook provided an objective score of the adjustment of doses actually performed. The results show that the subjective and objective scores of adjustment were not significantly correlated. Further there was a significant negative correlation between the score of uncertainty on knowledge and the subjective score of adjustment of the insulin doses, but not with the objective score. There was a significant correlationbetween the score of positive health beliefs and the subjective score of adjustment of the insulin doses, but not with the objective score. No correlation was found between the score of fear of hypoglycemia and the subjective score of adjustment of the insulin doses. Correlation with the objective score was higher, but not significant. Actually, the fear of hypoglycemia was the most frequently given reason for not adjusting the insulin doses, when the question was asked to the patients with an open answer. This study illustrates the difference between thinking and doing. It also shows that the degree of confidence in one’s own knowledge, the health beliefs, and the fear of hypoglycemia differently influence the perception that the patients have of their behavior, and what they really do. © 2004 Elsevier Ireland Ltd.
