Cet article expose le développement d’une méthodologie automatique pour la détection des changements du bâti en vue d'une mise à jour semi automatique des cartes urbaines. L'approche est basée sur la comparaison entre une carte existante et une image à très haute résolution spatiale (THRS) récente. Elle s'enchaine sur 4 étapes. D'abord l'image est segmentée pour produire des primitives. Ces dernières sont caractérisées par 4 catégories d'attributs. Des classifieurs avancés par apprentissage supervisé (CAAS) ont été utilisés dans l'étape de la classification. Le paramétrage optimal de ces classifieurs est obtenu automatiquement par validation croisée en se référant au meilleur taux d'erreur. La prédiction finale des objets est déduite par un combineur de multiples classifieurs (CMC) conçu à partir des 3 meilleurs CAAS. Enfin, une étape de détection des changements permet d'identifier les primitives qui représentent les changements du bâti. Les données utilisées concernent la ville de Rabat (Maroc). Une image QuickBird a été utilisée avec un plan existant à l'échelle 1:10,000. Indépendamment de la qualité de la forme des bâtiments détectés, la méthode offre des meilleurs taux en exhaustivité (91.7%) et en exactitude (81.5%). [less ▲]

L’image, sous ses divers aspects, a joué un rôle essentiel dans la vie des anciens Grecs, en particulier dans le domaine religieux, puisque elle était l’une des modalités de perception du divin. En Grèce, la figuration anthropomorphe des dieux est largement majoritaire. Toutefois, en se tournant vers un support particulier, le vase peint, et un type de représentation particulier, la statue divine, on montrera ici que l’anthropomorphisme a pu amener une certaine ambiguïté. Dans la céramique, les représentations de statues fonctionnent sur plusieurs modes, selon la chronologie. C’est ce que l’on propose d’analyser, en examinant un groupe de vases décorés d’un thème semblable et sur lesquels une divinité est représentée, mais soit sous la forme d’une figure « vivante », soit d’une statue plus ou moins bien caractérisée. Cette étude permettra d’aborder les concepts de « fixité » et de « mouvement » de/dans l’image, mais aussi d’explorer quelques pistes de réflexions sur l’image divine et, plus largement, sur les modes de représentation du divin en Grèce ancienne.

Purpose. The purpose of this study is to examine the effect of institutional investors ownership and activism on information asymmetry and stock market liquidity in France. Design/methodology/approach. Our sample includes 162 French-listed firms over a period ranging from 2007 to 2009. Our methodology relies on linear regressions using the method of ordinary least square(OLS). Befor examining the interaction between liquidity and institutional investors, we check for the existence of the endogeneity problem by applying the Durbin-Wu_Hausman test of Davidson and MacKinnon (1993). The results of the endogeneity test show that institutional investor ownership and stock liquidity are endogenous. A simultaneous equation model using the second least square method is then tested to address this problem. Findings The findings show that the proportion of institutional investors has a positive and significant effect on stock-market liquidity, which confirms the signal theory and trading hypothesis. These investors perform high trading activity which favourably affect market liquidity. The results suggests that pension funds manage huge assets decreasing transaction costs and improving liquidity. They display a positive signal to the market about more transparency and a low level of information asymmetry.These results highlight the institutional investors'role in defining the level of liquidity of assets on the French market. Our findings also stress the importance of developing institutional investors'demand for the Paris market in order to better assess firms'values, protect minority ownership and improve market liquidity. Originality/Value In the French institutional setting, institutional investors act as a control device since minority shareholder interests are less protected than in Anglo-American counterparts. This result highlights the significant rôle of institional investors in corporate governance structures and a finacila markets. Their prsence is a guarantee for minority interest protection and for improving market liquidity. [less ▲]

This research aims to formalize the spatiotemporal relationships of membership between individuals and the groups to which they belong. Specifically, we analyze how the membership to a community evolves over time considering past, present and future connections. The framework developed for this research is presented using an ontological approach. We demonstrate a specific domain ontology application for spatiotemporal membership using BFO2, an updated version of the Basic Formal Ontology. Key to this work is the representation of membership, modeled through different kinds of mereological relations possible with a group, for example, pre-member, active member, and alumni that capture how membership evolves and changes over time. The semantic web rule language (SWRL) is used to express the different spatiotemporal events that relate to membership and their consequences on membership such as subscription, graduation and reunion events. Mobility events are also included in the model. SWRL supports reasoning using the ontology and studying the evolution of membership between people and their various groups. We use the environment of a university community as an exemplar to develop and test the formalizations. However, the ideas are generalizable to a wide range of spatiotemporal domains, for example, these ideas hold for citizenship modeling or for consumers shopping at certain retail chains. The study of the evolution of membership connections between these entities and groups lends important insights for many different kinds of event planning. [less ▲]

The study of spatial patterns is of ecological importance in order to understand the causes of the distribution and abundance of organisms, and it also provides valuable basis for management and conservation. Amphipod crustaceans are key organisms in seagrass ecosystems. However, little attention has been paid to the spatial scales at which amphipod assemblages may vary. We examined variability patterns of amphipod populations inhabiting Posidonia oceanica meadows, over spatial scales spanning four orders of magnitude (1 to 1000 metres) and for two consecutive years. This study reports the scales that contributed most to spatial variation of amphipod assemblages and explores the potential processes of the observed patterns, with particular emphasis on habitat features. The number of species, the diversity and the density of some species, exhibited high variation across years. Most species showed the highest spatial variation in density and biomass at small scales (~1 and 10 m). Based on density data, the structure of amphipod assemblages did not differ at any scales investigated. The patchiness that occurred at small scales may have been only weakly related to habitat features. Instead, we postulated that behavioural processes of amphipods were likely good explanatory factors. Although, the small scale spatial variability can be an important feature of amphipod assemblages in P. oceanica meadows, many patterns probably remained undetected as they may occur at scales smaller than those investigated.
