For organisms with complex life histories, carry-over effects (COEs) can manifest between life stages, when conditions experienced by one stage influence the next, as well as trans-generationally, when the parental environment affects offspring. Here we used multiple global change-associated stressors to examine both forms of COE simultaneously in an intertidal limpet with mixed development (i....

RÉSUMÉ : Dans ce papier, nous nous intéressons à un cas particulier de planification d’agents sous contraintes d’horaires pour lequel nous menons un certain nombre d’investigations : borne inférieure (relaxation lagrangienne), heuristiques (constructive et approche par génération de coupes) et méthode exacte par décomposition de Benders. Des expérimentations numériques sur des instances réelles...

This paper seeks to analyze the way investors consider growth option values when pricing equity. To achieve this objective we study the effect on stock prices of a comparative case of direct foreign investment involving acquisition of two different growth options, whose valuation has already been well-documented in prior literature. The case consists of the two sequential investment stages carr...

OBJECTIVE The lifetime risk of maternal mortality, which describes the cumulative loss of life due to maternal deaths over the female life course, is an important summary measure of population health. However, despite its interpretive appeal, the lifetime risk of dying from maternal causes can be defined and calculated in various ways. A clear and concise discussion of both its underlying conce...

Inductive Logic Programming, which consists in learning clauses from examples, can be viewed as a cycle conception/validation leading to the acceptance of the induced program provided that it fulllls a certain criterion. We focus on the validation step in the context of empirical multi-predicate learning of normal clauses. Thanks to a compositional semantics, the classical validation step of th...

The rapid growth of information enables a large increase in needs of recommendation. To satisfy this need, Collaborative Filtering and Social Filtering are adopted as solutions for personalized music recommendation. Contemporary recommender systems based on collaborative filtering and social filtering always suffer problems of unreliable item similarity, rating sparsity, lack of rating and un-r...
