Subnational mapping of HIV incidence and mortality among individuals aged 15-49 years in sub-Saharan Africa, 2000-18: a modelling study
2021
Background. High-resolution estimates of HIV burden across space and time provide an important tool for tracking and monitoring the progress of prevention and control efforts and assist with improving the precision and efficiency of targeting efforts. We aimed to assess HIV incidence and HIV mortality for all second-level administrative units across sub-Saharan Africa. Methods. In this modelling study, we developed a framework that used the geographically specific HIV prevalence data collected in seroprevalence surveys and antenatal care clinics to train a model that estimates HIV incidence and mortality among individuals aged 15–49 years. We used a model-based geostatistical framework to e…
: Evolution of the examination at the end of college in sub-Saharan Africa
2004
The evolution of schooling in the developing systems in sub-Saharan Africa has brought a sizeable new population into the colleges. Unfortunately, the scarcity of resources and the need to pursue development of basic education prevents maintaining this population in the lycees. Thus the examination at the end of college becomes the focus of very stressful management of different currents and finds itself divided about aims which are not easy to reconcile. Original solutions can be found, as is the case in Mauretania, while the combination of better-known solutions may allow this examination to deal with these contradictions.
Les modèles de simulation pour la planification de l'éducation en Afrique subsaharienne. Une simplicité appauvrissante et inféconde
2014
More than elsewhere, the issues covering educational planning are important in sub-Saharan Africa. Simulation models are the main tool of this type of planning. Most were designed or inspired by the World Bank or UNESCO. Yet, these models are too simplistic. This simplicity is a choice, although it is badly argued. The resulting vagueness is totally unacceptable, although imperceptible due to the simplicity of the models, which are not testable by facts. The simulation models are thus a sham and African educational systems continue to suffer grave imbalance in the allocation of resources. The conception of quality models, designed with a genuine concern to guide action, is possible and urge…
Juba II, rey de los mauros y los libios
2013
Con la tesis Juba II, rey de los mauros y los libios, se analiza la transcendencia que para el Principado de Agusto tuvo la instauración de este príncipe norteafricano como rey de Mauritania. Partiendo del análisis de su origen númida y las relaciones de alianza y amistad que vincularon su familia a Roma, hechos de gran relevancia y ampliamente explicados en este trabajo, se acomete en profundidad el estudio de los restos numismáticos, epigráficos, literarios y arqueológicos que conducen a establecer las líneas de actuación de este monarca en su reino, a nivel socioeconómico, militar y político. En cuanto al primer ascpecto citado, del estudio realizado se desprende que este monarca llevó a…
Nouveaux enjeux pour l'école moyenne en Afrique
2005
05113; On constate aujourd'hui une augmentation massive de la scolarité des 12-16 ans dans les pays africains en développement. Ce phénomène est lié au développement voulu et obtenu des scolarités primaires.Pour diverses raisons, l'école moyenneconstitue un cycle terminal pour la grande majorité des enfants qui la fréquentent. Son organisation actuelle, telle qu'on peut l'observer dans différents pays, est cependant très proche du collège secondaire français et donc inapte à fournir le cadre adéquat pour un cycle terminal générateur de progrès économiques et sociaux.Bâti sur cette problématique de l'articulation entre les flux d'élèves, les contenus pédagogiques et les modalités d'organisat…
Ecological, morphological and genetic characterization of sympatric Haemonchus spp. parasites of domestic ruminants in Mauritania
1995
SUMMARYThe 4 species of ruminants (dromedary, zebu cattle, sheep and goat) in arid areas of Mauritania harboured Haemonchus spp. as the most frequent internal parasite. This was a rare situation where the 3 putative species, H. longistipes (dromedary), H. placet (zebu cattle) and H. contortus (sheep and goat) occurred sympatrically. The study was undertaken on hosts slaughtered at the Nouakchott abattoir, on the basis of monthly collection of worms. The environment was very unfavourable to H. placei and unfavourable to H. contortus, as intensity of infection remained low throughout the year, whereas infection in the dromedary was 10 to 20-fold higher. The survival strategies during the long…
