In this article we give a necessary and su±cient condition for a selfnormalized weak invariance principle, in the case of a strictly stationary Á-mixing sequence fXjgj¸1. This is obtained under the assumptions that the function L(x) = EX2 1 1fjX1·xg is slowly varying at 1 and the mixing...

In this paper we study strong approximations (invariance principles) of the sequential uniform and general Bahadur-Kiefer processes of long-range dependent sequences. We also investigate the strong and weak asymptotic behavior of the sequential Vervaat process, i.e., the integrated sequential...

In this paper, a comprehensive cost-benefit analysis is implemented for the project of Yueyang-Zhuzhou Oil Product Pipeline, considering all members of society as whole. We focus on the social welfare aspects of the project as well as the project's risk resistance capacity.

After reviewing some basic self-enforcing labour contracts models, we expose how self-enforcing labour market theory can help explain some important dynamic properties of key macroeconomic variables. Calmès (1999, 2003) detail how self-enforcing labour contracts improve the way macroeconomic...

We revisit the well-known weekend anomaly (Gibbons and Hess, 1981; Harris, 1986; Smirlock and Straks, 1986; Connolly, 1989; Giovanis, 2010) using an established macroeconometric technique known as spectral analysis (Granger, 1964; Sargent, 1987). Our findings show that using regression analysis with dichotomous...

It is well-known that traditional financial institutions like banks follow procyclical risk strategies (Rajan 2005, 2009, Shin 2009, Jacques 2010) in the sense that they increase their leverage in economic expansions and reduce it in recessions, which leads to a procyclical behaviour for their...

Tout projet comporte des dangers et sa réussite dépendra notamment de la façon dont son responsable arrivera à cerner les risques potentiels et à réduire la gravité de leurs conséquences. Les problèmes majeurs rencontrés dans des projets de bâtiment et de génie civil proviennent de...

Cette étude présente une comparaison de deux méthodologies multicritère d’aide à la décision, l’analyse hiérarchique de Saaty (AHP, Analytic Hierarchy Process) et les ensembles approximatifs (DRSA, Dominance- based rough set approach). Cette recherche a été appliquée dans le cas...

Intégrer le développement durable (DD) en entreprise implique de réviser totalement les modes de pensée et de développer des stratégies basées sur une performance tridimension- nelle économique, sociale et environnementale (triple bottom line).De ce constat, les entreprises du...

La progressive transformation normative de l’intime et du social modifie la notion de conflit, perturbe les routines individuelles et organisationnelles, questionne la façon d’apprendre, et génère un risque d’épuisement dépressif au sein des équipes projet. La médiation...
