A Knowledge Management Tool for the Interconnection of Communities of Practice

Abstract: In their daily practice, practitioners belong to local communities of practice CoPs within their organisation. This knowledge is rarely capitalised upon because discussions are mainly verbal. Practitioners can also belong to general CoPs online. Within these general CoPs, discussions are rarely linked to the context in which they appeared, since the members are from different companies or institutions. This paper 1 connects these two levels of CoPs by contacting practitioners belonging to CoPs centred on the same general activity but who are geographically distributed and 2 capitalises on the produced knowledge by contextualising, allowing it to be accessible and reusable by all the members. The authors detail the main results of the research: 1 a model of the interconnection of CoPs ICP to support knowledge sharing and dissemination; and 2 a specific knowledge management tool for the ICP knowledge base. The authors apply the model and platform to university tutors by: 1 developing a use case, which links the model and the TE-Cap 2 platform and highlights the new possibilities offered by the knowledge management tool; and 2 conducting a descriptive investigation lasting for five months.

Large dams and uncertainties : the case of the Senegal river (West Africa)

Abstract: This article examines the environmental and socioeconomic consequences of hydraulic infrastructural changes along the Senegal River valley and estuary. During the 1980s, two dams were built along the valley floor to facilitate hydroelectrical production and regular water supply for crop irrigation. In 2003, a breach was dug across Barbary Spit to alleviate flooding in the nearby Saint-Louis city. Although these structures helped regulate the river flow, they also resulted in a series of unforeseen impacts. The study examines these, after on-site measurements (topometry, water salinity, piezometry), analysis of hydrological data, field observations, and surveys with dam managers, state regional directions, and local stakeholders. It stresses the urgency of elaborating models of hydraulic management to limit the negative consequences of the hydraulic constructions. These models should consider the variety of water uses in the middle valley and delta, and also the water safety and quality (salinity) downrive...

Le Quercy au cœur du dernier maximum glaciaire. La couche 4 du Petit Cloup Barrat et la question de la transition badegoulo-magdalénienne

Abstract: Signale des les annees cinquante, le gisement quercinois du Petit Cloup Barrat a ete redecouvert au milieu des annees quatre-vingt-dix. Cette doline, situee a 800 metres de l’entree prehistorique de la grotte de Pech Merle, a fait l’objet de fouilles programmees entre 2004 et 2008. Menee aux abords d’une grotte-abri localisee a l’extremite ouest de la doline, cette operation a permis la mise en evidence de plusieurs niveaux d’occupations datant de la seconde moitie du Paleolithique superieur. Deux secteurs ont ete distingues, a partir des differentes signatures sedimentaires de la sequence stratigraphique : la zone avant, qui correspond a la partie « ouverte » de l’espace fouille, et la zone du fond, situee sous le porche. Dans la grotte, affectee par des phenomenes de soutirage karstique, le remplissage mis au jour documente une succession d’au moins trois techno-complexes distincts : la couche 10N, dont l’attribution reste a confirmer, fait suite a l’ensemble 8 ou se succedent Solutreen superieur, Badegoulien a raclettes et Magdalenien inferieur. Dans la zone avant, le Magdalenien moyen de la couche 3, remanie par la mise en culture de la doline, coiffe la couche 4, ensemble le mieux documente a ce jour et qui fait l’objet de cet article.Riche de plusieurs milliers de vestiges, cet ensemble presente certaines particularites : si la mauvaise preservation de la faune limite l’approche archeozoologique, les donnees acquises lors de l’analyse des productions lithiques et osseuses apportent en revanche de nombreux elements de discussion. La composante lithique, a travers la nature de certaines armatures et de leurs modalites de production, fait clairement echo a certaines industries du Magdalenien inferieur. Neanmoins, tandis que la plus grande part de la composante osseuse s’accorde pleinement avec cette proposition (type de pointe, extraction par rainurage longitudinal), une serie de pieces temoigne de la mise en œuvre d’un debitage du bois de renne par percussion habituellement exclu de ces ensembles. Cette « mixite » technique - qu’il conviendra de confirmer par le biais de datations directes - vient alimenter les debats actuels sur la transition badegoulo-magdalenienne. Enfin, la decouverte de plusieurs incisives d’herbivores sciees et d’une ebauche d’anneau ouvert en bois de renne renforce l’originalite de l’assemblage, ouvrant de nouveaux horizons de recherches.

DDART, a Dynamic Dashboard for Collection, Analysis and Visualization of Activity and Reporting Traces

Abstract: Most Learning Management Systems (LMS) focus on providing rich learning materials to the learners but rarely offer possibilities to monitor and analyze their learning processes. However metacognitive strategies argue that learners can improve their learning performances by monitoring their activities, especially in the context of Project-Based Learning (PBL). Our work consists in designing tools to support metacognitive strategies. In this paper, a framework and a dynamic dashboard for PBL situations are proposed to help learners to collect, analyze and visualize the meaningful traces of their activities by them-selves. The proposed framework integrates activity traces (interactions with the LMS) and reporting traces (semi-structured sentences written by the learners). The dynamic dashboard supports learners in the creation customizable indicators through a user-friendly interface.

Usages d'un intranet et processus de structuration de l'organisation

Abstract: The appraisal of economic or strategic added-value of Intranet technologies is a very difficult exercise. Sructurationnists shed light on this problem by considering IT uses at two levels. The first one which corresponds to appropriation first degree, that is to say the sense an individual gives to IT when he uses it. The second level, linked to appropriation second degree, lays in considering that an organization's deep social structures can evolve or reinforce themselves through IT use. By putting together theses evolutions with Critical Success Factor (CSF), we can then evaluate the possible value induced by the more innovative King of IT uses. Then, the study of France Telecom Lyon enables us to precise our model by confronting it to a concrete situation.
