Developmental Coordination Disorder (DCD) is a developmental disorder characterized by marked impairments in motor skills. Despite its negative impact on daily activities and on cognitive and academic performance, the mechanisms underlying DCD remain largely unknown. The aim of our study was to investigate the hypothesis of a motor procedural learning impairment in DCD, which would explain difficulties in motor learning and automation of novel motor skills in these children. A total of 32 children (16 with DCD and 16 typically developing [TD] children) aged between 6 and 12 years old participated in this study. Children were administered a task adapted from the traditional shapes’ mirror-tracing task. Results showed that DCD children were able to learn the skill as fast as TD children; the learning pattern of DCD and TD children in motor procedural learning is similar. But is there any generalization of a new perceptual-motor skill in DCD children? Actually, DCD children were slower during the transfer task (triangle task) than TD children; the transfer task was more difficult for the DCD children than their peers. DCD children and TD children differ in their abilities to generalize the motor schema to a new task, more complex. These results confirm the hypothesis of a motor procedural learning impairment in DCD. [less ▲]

Purpose: According to the Procedural Deficit Hypothesis (PDH), difficulties in the Procedural Learning (PL) system may contribute to the language difficulties observed in children with Specific Language Impairment (SLI). Method: Fifteen children with SLI and their typically developing (TD) peers were compared on visual PL tasks: specifically, deterministic Serial Reaction Time (SRT) tasks. In a first experiment, children with SLI and their TD peers performed the classical SRT task using a keyboard as response mode. In a second experiment, they performed the same SRT task but gave their responses through a touchscreen (instead of a keyboard) to reduce the motor and cognitive demands of the task. Results: Although in Experiment 1, children with SLI demonstrated learning, they were slower and made more errors than their TD peers. Nevertheless, these relative weaknesses disappeared when the nature of the response mode changed (Experiment 2). Conclusions: This study reports that children with SLI may exhibit sequential learning. Moreover, the generally slower RTs observed in previous deterministic SRT studies may be explained by the response mode used. Thus, our findings are not consistent with the predictions of the PDH, and suggest that language impairments in SLI are not sustained by poor procedural learning abilities. [less ▲]

Les modèles multimodaux de fret so ellement basés sur le modèle à quatre étapes dans lequel la génération, la distribution, la répartition modale et l’affectation sont autant de modules séparés. Une approche alternative est de représenter le réseau multimodal par un réseau de service dans lequel chaque opération de transport (chargement, déchargement, transbordement,…) est représentée par un « arc virtuel » dédié. Dans un tel réseau, le choix-modal et l’affectation peuvent être effectués en une seule étape. Cette approche, adoptée par plusieurs auteurs et connue sous les vocables « super-rése aux » ou « réseaux virtuels » donne des résultats intéressants, mais nécessite la mise enoeuvre de méthodes d’affectation appropriées, qui peuvent répartir les flux d’une origine à une destination particulière entre des itinéraires alternatifs. Il s’avère que les techniques d’affectation d'équilibre ne conviennent pas lorsqu’elles son t utilisées sur des réseaux internationaux pour lesquels seules des données agrégées pour la demande sont disponibles. En effet, les solutions obtenues sont très proches d’une affectation « tout ou rien », et n’aboutissent donc pas à une répartition suffisante entre chemins alternatifs. Ceci peut principalement être expliqué par le fait que, dans le trafic interurbain, interrégional ou international, une petite partie du voyage seulement est faite pendant les heures de pointes dans des zones congestionnées. De plus, les données de demande collectées sur de grandes zones sont souvent disponibles uniquement sur base annuelle, rendant difficile une estimation fine pour une période donnée du jour. C’est dans ce contexte que cet article décrit une technique d’affectation multi-flux qui peu t être appliquée sur de grands réseaux virtuels de transport de fret. L’article se termine avec une application de la méthode au réseau transeuropéen. [less ▲]

A procedure for modelling asymptotic g-mode pulsators: The case of gamma Doradus stars

Mode identification is one of the first and main problems we encounter in trying to develop the complete potential of asteroseismology. In the particular case of {g}-mode pulsators, this is still an unsolved problem, from both the observational and theoretical points of view. Nevertheless, in recent years, some observational and theoretical efforts have been made to find a solution. In this work we use the latest theoretical and computational tools to understand asymptotic {g}-mode pulsators: 1) the Frequency Ratio Method, and 2) Time Dependent Convection. With these tools, a self-consistent procedure for mode identification and modelling of these {g}-mode pulsators can be constructed. This procedure is illustrated using observational information available for the gamma Doradus star 9 Aurigae. [less ▲]

A successful spray application doesn't only depend on the choice of the appropriate chemical product and on the treatment period, but also depends on the user's abilities and the working order of the crop sprayer. The experience shows that these two points often pose a problem. Concerning the equipment, many countries have taken initiatives for the sprayers control. This one is usually free but the tendance is to make it obligatory. The control method implemented in Belgium (Wallon region) is different from the general method based on the use of a spray pattern collector: it is completely mobile and is essentially based on the measure of the pressure at the boom and of the nozzles output. The results show that many sprayers are not in a good working order. [less ▲]
