Studied between 1994 and 1998, the site located on Enez Vihan island revealed archaeological remains linked to sait production. This craft complex, dating from II-Ist centuries B.C., includes a workshop, small building with a stone architecture, with spécifie lay-out (kiln, tanks, pits) and an outhouse, a sort of lean-to, used as storage and refuse outlet. Besides a detailed analysis of the archaeological remains, including ceramics which are quite numerous for a site of this type, a shaped study of the « bnquetage » (bricks, hand-bricks and sait moulds), elements of which were collected dozen of kilos, offers the opportunity to evaluate the sait production for each batch. In view of the regional context and the comparative elements, especially with the nearby site of Landrellec, mis study leads to a technological characterisation of the sait production in Tregor during the late Iron Age.

On line elaboration of a mental model during the understanding of an animationThis experiment aimed at studying how high and low spatial abilities adult learners understood an animation. Two factors were manipulated when learners were studying a threepulley system device: the controllability of the animation and the orientation of the attention of the participant by an explicit task. Off-line (comprehension questions) and on-line (eye tracking) measures were used. The comprehension test results indicated that, more than controllability, the specific orientation of the attention of the participant on the relevant features of the animation had a positive effect on the elaboration of a high quality dynamic mental model of the device. This positive effect appeared particularly when the attention of the learner was focused on the functional model and on local kinematics. The eye tracking data indicated that the learners attend more to the areas of the animations where a great amount of motion is involved along the causal chain of events. We showed an effect of the controllability of the system and of the orientation of the learner’s attention on the amount of eye fixations and on the number of transitions between areas that included the causal chain. The elaboration of the mental model of an animation seemed to require a piecemeal processing, step by step, of the operations of the system et not the direct analogue and holistic mapping of the device.

Les PME à forte croissance et la métaphore du jazz. Comment gérer l'improvisation de façon cohérente
More informationThe jazz band metaphor seems particularly useful in understanding the behaviour of fast growth firms. We used it in case studies of 52 small and medium-sized fast-growth firms in Québec. Beyond the growth of the sector itself, our results show that the success of fast-growth firms (“ gazelles”) depends on their ability to respond to their customers' needs, to manage change and to reorganize their organization systematically. Their management is experienced and communicative, and the firms have a very strong market orientation, particularly for exporting. However, as with a very good jazz band, the organization of such firms is particularly complex, decentralized, participative and learning in nature, linked by a dynamic and evolutive culture. And, like the better free jazz bands, the firms make use of resources in the environment, including private and public consultants, to innovate and change and also maintain special contacts with higher educational institutions and R-D centres. Such firms therefore act like free jazz bands by taking advantage of visiting players to improvize with greater harmony, to innovate, and to respond with new knowledge to an audience “in the know”.
