La présente étude se consacre à la réflexion sur la corrélation entre l’infrastructure routière et le développement socioéconomique. C’est en s’appuyant sur un ensemble très large de variables sociales et économiques jugées pertinentes que cette étude tente de contribuer à la construction d’un dispositif des variables aptes à saisir les changements entraînés par l’intervention du projet routier basée sur la technologie HIMO. Malgré quelques différences, la plupart des variables/indicateurs gardent les mêmes tendances évolutives dans ces différentes régions. Au-delà de notes de succès socioéconomique enregistré, des points d’attention subsistent et méritent des réflexions correctives dans une logique de poursuite et d’extension des activités de réhabilitation routière, notamment la persistance d’inégalités de genre dans les chances d’accès au travail, l’absence d’actions complémentaires devant appuyer les activités agropastorales et la persistance de la problématique de prise en charge de l’entretien du réseau réhabilité par les ressources tant locales, provinciales que nationales. L’étude repose essentiellement sur les données secondaires consignées dans les différents documents et rapports en les analysant dans une approche comparative avec les résultats obtenus par d’autres études réalisées en République Démocratique du Congo et dans d’autres régions en Afrique subsaharienne, dont particulièrement le Burkina Faso et le Bénin.

In this paper, we consider a regression model in which the tail of the conditional distribution of the response can be approximated by a Generalized Pareto distribution. Our model is based on a semiparametric single-index assumption on the conditional tail index; while no further assumption on the conditional scale parameter is made. The underlying dimension reduction assumption allows the procedure to be of prime interest in the case where the dimension of the covariates is high, in which case the purely nonparametric techniques fail while the purely parametric ones are too rough to correctly fit to the data. We derive asymptotic normality of the estimators that we define, and propose an iterative algorithm in order to perform their practical implementation. Our results are supported by some simulations and a practical application on a public database of operational losses. [less ▲]

BACKGROUND: Gait impairment seems to be a risk factor for falls and mortality. Because gait change cannot be determined easily with classical clinical tests, some authors have suggested that it might be useful to use a gait-analysis system among elderly community-dwelling people. OBJECTIVE: The main objective of the present study was to determine the predictive value of a quantitative evaluation of the gait characteristics in nursing home residents for the occurrence of falls and death performed using a tri-axial accelerometer (Locometrix(R)). MATERIAL AND METHODS: One hundred elderly nursing home residents (80 women and 20 men, mean age 86.4 +/- 6.04 years) were included in this study with the aim to follow them for 2 years. Deaths and falls were systematically recorded. A quantitative evaluation of a 10-second walk was performed with a tri-axial accelerometer (Locometrix(R)). Demographic data (i.e age, sex, body mass index) and clinical data (i.e. fall risk evaluated by the Tinetti test) were also recorded. RESULTS: During the two years of follow-up, 27 patients died. After adjustment on all potential confounding variables, only body mass index was significantly associated with the risk of mortality with an odds ratio of 0.86 (95% CI: 0.77-0.96, p=0.04). At the end of the study period, 440 falls had occurred (mean: 4.44 +/- 6.79 falls per patient) but no single factors were independently associated with fall incidence. CONCLUSION: Our results show that a quantitative gait analysis performed using a tri-axial accelerometer is not predictive of long-term falls and mortality among nursing home residents. [less ▲]

L’infrastructure des transports constitue l’un des piliers du développement africain. Car, en tant qu’activité transversale, le transport exerce une grande influence sur tous les domaines socio-économiques et est appelé à jouer un rôle primordial dans l’accélération de la croissance et la réduction de la pauvreté. Compte tenu des caractéristiques économiques et géographiques de l’Afrique et tenant compte de la protection de l’environnement, l’infrastructure ferroviaire constitue ainsi l’épine dorsale des activités économiques et sociales de ce continent. Fort malheureusement, à l’exception de quelques cas isolés, la quasi-totalité des réseaux ferroviaires africains ont accumulé d’importants retards dans leur modernisation. De plus, la qualité de gestion de ces compagnies est souvent mise en question. Eu égard à ce qui précède, cet ouvrage a pour principal objectif d’établir un état des lieux des chemins de fer africains. De ce fait, il contribue, sans nul doute, à une meilleure compréhension des mécanismes économiques et de gestion des entreprises ferroviaires africaines sur plusieurs aspects : nécessité économique du rail – cadre institutionnel – viabilité des réseaux.

This paper presents recent investigations in the field of lubricant escapes from asperities. This phenomenon, named Micro Plasto Hydrodynamic Lubrication (MPHL), induces friction variation during metal forming processes. A better understanding of MPH lubrication would lead to a better management of friction, which is a central element in most sheet metal forming processes. To fulfil that goal, experiments were conducted in plane strip drawing using a transparent upper tool in order to observe lubricant flow around macroscopic pyramidal cavities. These experiments were then numerically reproduced with two complementary Finite Element models. The numerical results are discussed in this paper and show good agreement with experimental measurements. [less ▲]
