We investigate the approximation of the Lovász extension of a pseudo-Boolean function by the Lovász extension of a multilinear polynomial of (at most) a specified degree. Certain constrained versions of this approximation problem are also studied. Finally, we apply this theory to the aggregation phase of a multicriteria decision making problem. [less ▲]

The present study is based on predictions developed in the field of evolutionary psychology concerning the existence of sex differences in verbal and visuo-spatial abilities, namely in navigational abilities (MARTIN 1998), in mastery of water-level horizontality (ROBERT 1990), geographic knowledge, spatial memory (EALS & SILVERMAN 1994) and verbal fluencies. We investigated the potential influence of verbal processes on the processing of visuo-spatial information. Cross-modality conditions were thus used, which required verbal processing of visuo-spatial inputs at different levels. The significant results obtained all show a male advantage: in spatial navigation, in mastery of water-level horizontality, in geographic knowledge (names of countries), but also in spatial location memory, as well as in a verbal fluencies task (animal condition), although no such advantages were expected here. No female advantage was found, not even for the "female" task. This clearly restricts the conclusions that could be drawn from our study. Overall, the performances in tasks requiring verbal encoding of spatial information are very similar to those in classical (spatial) conditions, or they are not directly linked to language processing. Thus no clear-cut conclusions can be made about the intervention of verbal processes in navigational behaviour or spatial memory. The verbal fluency task on names of countries yielded a male advantage suggesting a male superiority in rapidly accessing information represented - in a visuo-spatial format - in long-term memory. This result clearly contrasts with Halpern et al.’s (1996) process-oriented model of cognitive sex differences. On the other hand, the spatial precision of geographic representations in males are rather low, as is suggested by the results in a task about relative positions of countries of the American continent. It seems that the quality of spatial discourse depends more on the quality of spatial representations than on verbal abilities. [less ▲]

In this paper, we present a model allowing to determine the weights related to interacting (correlated) criteria. This is done on the basis of the knowledge of a partial ranking over a reference set of alternatives (prototypes), a partial ranking over the set of criteria, and a partial ranking over the set of interactions between pairs of criteria.

Seconde édition: Cet ouvrage est un livre d'initiation aux mécanismes de l'économie actuelle. De quoi dépend notre salaire ? Comment naît, vit et meurt une entreprise ? Quels sont les mécanismes du marché et les limites de l'État ? D'où vient la monnaie ? Que se passe-t-il dans la finance internationale ? Peut-on supprimer le déficit extérieur, gagner sur le chômage, vaincre l'inégalité, le sous-développement et la misère ? Quelles sont les perspectives ouvertes par le marché unique européen ? L'auteur répond à toutes ces questions. Simplement dans le langage de tous les jours. Pour que chacun, et notamment les étudiants en économie et les cadre spécialisés connaissent et comprennent les règles du jeu économique. Le contenu de ce livre est idéal pour préparer efficacement les examens d'économie. Conforme aux programmes officiels français, il est construit sous la forme de 35 fiches de révision, courtes mais complètes, accompagnées d'exercices nombreux et variés, tous corrigés. En fin d'ouvrage figurent quelques rappels et conseils concernant l'épreuve d'économie, ainsi qu'une courte bibliographie. [less ▲]
