Ce mémoire est l’occasion de partager le résultat de la mise en place de ce dispositif de formation à distance que nous avons mené dans l’université du Cap-Vert. Dans la première partie, nous décrirons la nature de la politique éducative au Cap-Vert. Nous contextualiserons les principes de l’installation de l’université publique dans ce pays, ainsi que les intentions d’innovation pédagogique de cette université. La deuxième partie portera un regard complémentaire sur l’utilisation des TIC et de l’internet dans l’enseignement/apprentissage d’une langue, cas du français langue étrangère, et nous nous inspirerons des théories constructiviste et socio-constructiviste. Finalement, la troisième partie détaillera toutes les étapes de la conception et de la mise en place du dispositif de formation à distance. Dans cette troisième partie, nous aborderons dans un premier temps la question des enjeux et des risques du e-Learning et nous présenterons notre mission dans le projet « e-Learning.cv » mené par l’université. Puis, dans un deuxième temps nous analyserons quelques cours que nous avons mis en ligne, en sachant qu’un cours en ligne n’est pas la simple reproduction d’un support pédagogique imprimé mais il offre à l’apprenant un environnement multimédia et interactif. Finalement dans un troisième temps nous essayerons de prendre un peu de recul pour faire une analyse critique de ce que nous avons réalisé et essayer par là même de dégager les perspectives pour améliorer le travail effectué.

One aspect of person-job fit reflects congruence between personal preferences and job design; as congruence increases so should satisfaction. We hypothesized that power distance would moderate whether fit is related to satisfaction with degree of job formalization. We obtained measures of job-formalization, fit and satisfaction, as well as organizational commitment from employees (n = 772) in a multinational firm with subsidiaries in six countries. Confirming previous findings, individuals from low power-distance cultures were most satisfied with increasing fit. However, the extent to which individuals from high power-distance cultures were satisfied did not necessarily depend on increasing fit, but mostly on whether the degree of formalization received was congruent to cultural norms. Irrespective of culture, satisfaction with formalization predicted a broad measure of organizational commitment. Apart from our novel extension of fit theory, we show how moderation can be tested in the context of polynomial response surface regression and how specific hypotheses can be tested regarding different points on the response surface.

A new parametric minimum distance time-domain estimator for ARFIMA processes is introduced in this paper. The proposed estimator minimizes the sum of squared correlations of residuals obtained after filtering a series through ARFIMA parameters. The estimator iseasy to compute and is consistent and asymptotically normally distributed for fractionallyintegrated (FI) processes with an integration order d strictly greater than -0.75. Therefore, it can be applied to both stationary and non-stationary processes. Deterministic components are also allowed in the DGP. Furthermore, as a by-product, the estimation procedure provides an immediate check on the adequacy of the specified model. This is so because the criterion function, when evaluated at the estimated values, coincides with the Box-Pierce goodness of fit statistic. Empirical applications and Monte-Carlo simulations supporting the analytical results and showing the good performance of the estimator in finite samples are also provided.

The set covering problem is an NP-hard combinatorial optimization problemthat arises in applications ranging from crew scheduling in airlines todriver scheduling in public mass transport. In this paper we analyze searchspace characteristics of a widely used set of benchmark instances throughan analysis of the fitness-distance correlation. This analysis shows thatthere exist several classes of set covering instances that have a largelydifferent behavior. For instances with high fitness distance correlation,we propose new ways of generating core problems and analyze the performanceof algorithms exploiting these core problems.
