Poussés par la demande des étudiants branchés, un grand nombre d’universités et d’établissements scolaires se sont lancés dans le design, le développement et l’utilisation des technologies de l’information et de la communication pour créer, partager et diffuser leur matériel pédagogique. Le but de notre de recherche est de favoriser l’accès aux ressources pédagogiques afin de promouvoir la form...

Should a country invest more in human or physical capital? The present paper addresses this issue, considering the impact of different factor intensities between sectors on both optimal human and physical capital accumulation. Using a two-sector overlapping generations setting with endogenous growth driven by human capital accumulation, we prove that relative factor intensity between sectors dr...

We use a stochastic frontier approach to study the effects of political and regulatory institutions on aggregate productivity in 39 countries from 1975 to 1990. We show that technical efficiency is positively related to policies supporting laissez-faire and political structures that promote policy stability. Moreover, models of technical efficiency incorporating both measures perform better tha...

This article introduces MLPOST, an OCaml library for scientific drawing. It is based on METAPOST, which allows inclusion of LTEX fragments. OCaml is an appealing alternative to LTEX macro languages, dedicated languages and even to graphic tools. In particular, MLPOST users benefit from OCaml’s expressiveness and static typing. Finally, MLPOST features a declarative style, which differs from the...

Mobile application users want to consume location-based services without disclosing their locations and data owners (DO) want to provide different levels of service based on consumer classifications, sometimes without disclosing areas of interest (AOI) locations to all users. Both actors want to leverage location-based services utility without sacrificing privacy. We propose a protocol that sup...

One common assumption when defining location privacy metrics is that one is dealing with attackers who have the objective of re-identifying an individual out of an anonymized data set. However, in today’s communication scenarios, user communication and information exchange with (partially) trusted peers is very common, e.g., in communication via social applications. When disclosing voluntarily ...
