This study investigates whether European firms reporting under domestic GAAPs exhibit major differences while examining the relationship between their economic (financial, operating and competitive) performance and their recognized intangible investment (RII). Using a five-European-country...

We prove that the problem of deciding whether a graph has a balanced skew partition is NP-hard. We give an O(n9)-time algorithm for the same problem restricted to Berge graphs. Our algorithm is not constructive : it certifies that a graph has a balanced skew partition if it has one. It relies on...

We give a structural description of the class C of graphs that do not contain a cycle with a unique chord as an induced subgraph. Our main theorem states that any connected graph in C is a either in some simple basic class or has a decomposition. Basic classes are cliques, bipartite graphs with...

Ce tutoriel montre, de façon intuitive et sans formalisme excessif, les principales notions théoriques nécessaires à la compréhension et à l'interprétation des résultats d'analyses de régression linéaire, simple et multiple, produits par la procédure REG de SAS® et par le menu FIT de...

In this article we demonstrate, through the case of Egypt, how the emphasis on one specific learning mode from primary through to secondary school, and to a lesser extent, culture, impact learning abilities. We describe how Egyptian students are impaired when confronted to learning modes they...

IT Technologies are said to make access to learning easier and cheaper. Virtually all theorical knowledge is available in one form or another on the web, with possibilities for beginners as well as, in certain cases, for extremely sophisticated users.

The promotion of Life Long Learning (LLL) has become a high priority in the economic and social agenda of OECD countries. It is considered as one of the corner stones of the "active welfare state". Several countries have introduced (or at least experimented) Individual Learning Accounts as a way...
