The aim of this work is to review the literature on full truck load transportation service procurement and identify the gaps from the points of view of researchers and practitioners. Full truck load procurement is particularly considered for review since it is encountered more in freight movement than others forms and also it has many challenges. A framework is developed to have a...

One of the fastest growing approaches to teaching and learning in the new digital paradigm is the use of Massive Open Online Courses (MOOCs). They are categorised either as cMOOCs following a connectivist approach, or as xMOOCs based on behaviourist principles. However, in xMOOC environments, forums may play a real connectivist role if they are functioning as a community. This paper...

Cet article analyse les perceptions, comportements et rapports à la forêt de la population du canton de Genève (Suisse), révélés par un sondage effectué en hiver 2014. On constate que les Genevois utilisent la forêt de façon moins intensive que la population des autres cantons suisses et valorisent moins l’aspect économique de la forêt. La majorité des répondants privilégient la...

Social norms have been included in the theory of collective action to overcome difficulties in explaining why commons may perform better when self-regulated. The role of trust has been identified in several contexts of local social dilemmas, but only recently has been extended to global commons, based on large descriptive evidence collected by Elinor Ostrom. However, no quantitative...

Cette étude examine dans quelle mesure les informations ESG (Environnement, Social et Gouvernance d’entreprise), agrégées sous forme de scores, peuvent influencer les rendements mensuels des actions sur les marchés en Suisse, aux États-Unis, et au Royaume-Uni, au cours de la période 2007-2011. Nous constatons que la variation de la note globale ESG n’est significative qu’au Royaume-...

The steady Eikonal equation is a prototypical first-order fully nonlinear equation. A numerical method based on elliptic solvers is presented here to solve two different kinds of steady Eikonal equations and compute solutions, which are maximal and minimal in the variational sense. The approach in this paper relies on a variational argument involving penalty, a biharmonic...

In this article, we discuss a numerical method for the computation of the minimal and maximal solutions of a steady scalar Eikonal equation. This method relies on a penalty treatment of the nonlinearity, a biharmonic regularization of the resulting variational problem, and the time discretization by operator-splitting of an initial value problem associated with the Euler-Lagrange...

In this paper, we test for scope effects in Contingent Valuation applying different distributional assumptions for WTP, a non-parametric estimation and an estimation based on an open-ended format. Mean WTP is sensitive to the distributional assumption, but so is the scope effect. The nonparametric model, without conditions on the distribution, is the best able to identify scope...

Les Linked Open Data (LOD) mettent peu à peu en évidence des enjeux considérables pour les professionnels de l'information et les bibliothèques. Cet article fait un tour d'horizon de la question en abordant plusieurs aspects. Après avoir introduit les concepts-clés de cette thématique, il s'attache à déterminer l'utilité des LOD en bibliothèque en présentant...
