Le redoublement, la réussite scolaire et l’objectif de la Scolarisation Primaire Universelle (SPU) d’ici à 2015 dans le cadre de l’Éducation Pour Tous (EPT) : cas du Sénégal à partir des données longitudinales du PASEC

L’Éducation Pour Tous mobilise la communauté internationale et les gouvernements depuis 1990. Cet engagement global renouvelé en 2000 sous l’auspice de l’UNESCO puis des Nations-Unies, porte notamment sur un objectif de base : l’universalisation de la scolarisation primaire complète pour tous les enfants d’âge scolaire à l’horizon de 2015. Plusieurs études sur la réalisation de cet objectif montrent que les pays en développement sont les plus à risque et que les progrès accomplis dans la plupart de ces pays, pourraient être plus importants si la pratique du redoublement faisait davantage l’objet de régulation et de contrôle. Cela contribuerait à améliorer la réussite scolaire et accroître la rétention des élèves au sein des systèmes éducatifs. La pratique du redoublement est en effet une tradition dans plusieurs systèmes éducatifs. Elle est particulièrement prépondérante dans certains groupes de pays ou régions, notamment en Afrique francophone au sud du Sahara. Dans ces pays, le PASEC - Programme d’Analyse des Systèmes Éducatifs de la CONFEMEN (Conférence des Ministres de l’Éducation Nationale des pays ayant le français en partage) - œuvre à améliorer l’accès à une éducation de qualité pour tous, par exemple, en informant les politiques sur la situation nationale du redoublement. Cette recherche sur le redoublement, la réussite scolaire et l’objectif de la Scolarisation Primaire Universelle (SPU) privilégie la dimension pédagogique, l’analyse empirique et étudie le cas du Sénégal. Elle présente et discute les indicateurs internationaux de suivi de l’objectif de la SPU, fait le point de l’état des connaissances sur le redoublement et la réussite scolaire et montre le défi que représente la réalisation de l’objectif de la SPU notamment dans les pays francophones d’Afrique sub-Saharienne. Exploitant les données existantes de l’enquête longitudinale de suivi de cohorte du PASEC au Sénégal entre 1995 et 2000, cette recherche examine le parcours scolaire des élèves en vue de la réalisation de l’objectif de la SPU. L’examen effectué combine des approches d’analyse transversale et longitudinale du redoublement et des apprentissages par rapport aux caractéristiques personnelles, familiales et scolaires de l’élève. Les résultats d’analyse montrent des variabilités, notamment par rapport aux caractéristiques personnelles de l’élève et à celles de sa classe et de son milieu de scolarisation. L’analyse longitudinale du redoublement s’est appuyée sur le diagramme de flux scolaire et a permis de produire un ensemble d’indicateurs d’efficacité interne du système éducatif du Sénégal. Pour la cohorte étudiée, du fait de l’importance des redoublements et des abandons scolaires, il faut en moyenne 9,4 années de scolarité pour que l’élève progresse du deuxième au sixième (dernier) grade du primaire. Seulement 39% de l’effectif de la cohorte survivent au dernier grade ce qui suggère que si cette tendance se maintenait, le Sénégal serait à risque de ne pas réaliser l’objectif de la SPU. Une évaluation de la situation courante à partir de données plus récentes serait requise. Le diagramme de flux scolaire constitue un outil de planification de l’éducation et représente de ce fait un important levier aux mains des autorités politiques pour agir sur les paramètres du système éducatif (paramètres liés à la qualité de l’éducation, à l’efficacité interne, etc.) afin de répondre à des objectifs spécifiques ou d’étapes pouvant conduire, par exemple, à la réalisation de l’objectif de la SPU.

Choice of macroinvertebrate metrics to evaluate stream conditions in Atlantic Forest, Brazil

The development of biomonitoring programs based on the macroinvertebrate community requires the understanding of species distribution patterns, as well as of the responses of the community to anthropogenic stressors. In this study, 49 metrics were tested as potential means of assessing the condition of 29 first- and second-order streams located in areas of differing types of land use in So Paulo State, Brazil. Of the sampled streams, 15 were in well-preserved regions in the Atlantic Forest, 5 were among sugarcane cultivations, 5 were in areas of pasture, and 4 were among eucalyptus plantations. The metrics were assessed against the following criteria: (1) predictable response to the impact of human activity; (2) highest taxonomic resolution, and (3) operational and theoretical simplicity. We found that 18 metrics were correlated with the environmental and spatial predictors used, and seven of these satisfied the selection criteria and are thus candidates for inclusion in a multimetric system to assess low-order streams in So Paulo State. These metrics are family richness; Ephemeroptera, Plecoptera and Trichoptera (EPT) richness; proportion of Megaloptera and Hirudinea; proportion of EPT; Shannon diversity index for genus; and adapted Biological Monitoring Work Party biotic index.

Transcorneal Electrical Stimulation for Patients with Retinitis Pigmentosa: A Prospective, Randomized, Sham-Controlled Exploratory Study

PURPOSE. To assess the safety of transcorneal electrical stimulation (TES) and explore its efficacy in various subjective and objective parameters of visual function in patients with retinitis pigmentosa (RP). METHODS. Twenty-four patients in this prospective, randomized, partially blinded, good-clinical-practice study underwent TES (5-ms biphasic pulses; 20 Hz; DTL electrodes) 30 minutes per week for 6 consecutive weeks. The patients were randomly assigned to one of three groups: sham, 66%, or 150% of individual electrical phosphene threshold (EPT). Visual acuity (VA), visual field (VF; kinetic, static), electroretinography (Ganzfeld, multifocal), dark-adaptation (DA), color discrimination, and EPTs were assessed at all visits or four times, according to the study plan. RESULTS. TES using DTL electrodes was tolerated well; all patients finished the study. Two adverse (foreign body sensation), but no serious adverse events were encountered. There was a tendency for most functional parameters to improve (8/18) or to remain constant (8/18) in the 150% group. VF area and scotopic b-wave amplitude reached statistical significance (P < 0.027 and P < 0.001, respectively). Only desaturated color discrimination and VF mean sensitivity decreased. There was no obvious trend in the 66% group. CONCLUSIONS. TES was found to be safe in RP patients. Positive trends were discovered, but due to the small sample size of this exploratory study, statistical significance was reached only for VF area and scotopic b-wave amplitude. Further studies with larger sample sizes and longer duration are needed to confirm the findings and to define optimal stimulation parameters. (ClinicalTrials.gov number, NCT00804102.)

Criação de programa informático em ambiente Matlab® para estudo de estruturas planas pelo Método de Elementos Finitos.

Os modelos a ser analisados pelo Método de Elementos Finitos são cada vez mais complexos e, nos tempos que correm, seria impensável realizar tais análises sem um apoio computorizado. Existe para esta finalidade uma vasta gama de programas que permitem realizar tarefas que passam pelo desenho de estruturas, análise estática de cargas, análise dinâmica e vibrações, visualização do comportamento físico (deformações) em tempo real, que permitem a otimização da estrutura. Sob o pretexto de permitir a qualquer utilizador uma análise de estruturas simples com o Método dos Elementos Finitos, surge esta tese, onde se irá criar de raiz um programa com interface gráfica no ambiente MATLAB® para análise de estruturas simples com dois tipos de elemento finito, triangular de deformação constante e quadrangular de deformação linear. O software desenvolvido, verificado por comparação com um software comercial dedicado para o efeito, efetua malhagem com elementos bidimensionais triangulares e quadriláteros e resolve modelos arbitrados pelo Método de Elementos Finitos, representando estes resultados visualmente e em formato tabular.

Assessing the performance of macroinvertebrate metrics in the Challhuaco-Ñireco System (Northern Patagonia, Argentina)

ABSTRACT Seven sites were examined in the Challhuaco-Ñireco system, located in the reserve of the Nahuel Huapi National Park, however part of the catchment is urbanized, being San Carlos de Bariloche (150,000 inhabitants) placed in the lower part of the basin. Physico-chemical variables were measured and benthic macroinvertebrates were collected during three consecutive years at seven sites from the headwater to the river outlet. Sites near the source of the river were characterised by Plecoptera, Ephemeroptera, Trichoptera and Diptera, whereas sites close to the river mouth were dominated by Diptera, Oligochaeta and Mollusca. Regarding functional feeding groups, collector-gatherers were dominant at all sites and this pattern was consistent among years. Ordination Analysis (RDA) revealed that species assemblages distribution responded to the climatic and topographic gradient (temperature and elevation), but also were associated with variables related to human impact (conductivity, nitrate and phosphate contents). Species assemblages at headwaters were mostly represented by sensitive insects, whereas tolerant taxa such as Tubificidae, Lumbriculidae, Chironomidae and crustacean Aegla sp. were dominant at urbanised sites. Regarding macroinvertebrate metrics employed, total richness, EPT taxa, Shannon diversity index and Biotic Monitoring Patagonian Stream index resulted fairly consistent and evidenced different levels of disturbances at the stream, meaning that this measures are suitable for evaluation of the status of Patagonian mountain streams.

Effects of forest conversion on the assemblages' structure of aquatic insects in subtropical regions

The effects of forest conversion to agricultural land uses on assemblages of aquatic insects were analyzed in subtropical streams. Organisms and environmental variables were collected in six low-order streams: three streams located in a forested area, and three in areas converted to agricultural land uses. We expected that the aquatic insects' assemblage attributes would be significantly affected by forest conversion, as well as by environmental variables. Streams in converted areas presented lower species richness, abundance and proportion of sensitive insect taxa. The ANOSIM test evidenced strong difference in EPT assemblage structure between streams of forested and converted areas. The ISA test evidenced several EPT genera with high specificity to streams in forested areas and only one genus related to streams in converted areas. Thus, the impacts of the conversion of forested area to agricultural land uses have significantly affected the EPT assemblages, while environmental variables were not affected. We suggest that the effects detected can be influenced by two processes related to vegetation cover: i) lower input of allochthonous material, and ii) increased input of fine sediments in streams draining converted areas.

Benthic macroinvertebrates assemblages and macrohabitat connectivity in Mediterranean-climate streams of northern California

Abstract. Drought leads to a loss of longitudinal and lateral hydrologic connectivity, which causes direct or indirect changes in stream ecosystem properties. Changes in macrohabitat availability from a rifflepool sequence to isolated pools are among the most conspicuous consequences of connectivity loss. Macroinvertebrate assemblages were compared among 3 distinct stream macrohabitats (riffles [R], pools connected to riffles [Pc], disconnected pools [Pd]) of 19 Mediterranean-climate sites in northern California to examine the influence of loss of habitat resulting from drought disturbance. At the time of sampling, 10 sites were perennial and included R and Pc macrohabitats, whereas 9 sites were intermittent and included only Pd macrohabitats. Taxa richness was more variable in Pd, and taxa richness was significantly lower in Pd than in Pc but not R. These results suggested a decline in richness between Pc and Pd that might be associated with loss of connectivity. Lower Ephemeroptera, Plecoptera, and Trichoptera (EPT) richness relative to Odonata, Coleoptera, and Heteroptera (OCH) richness was observed for Pd than R and Pc macrohabitats. Family composition was more similar between R and Pc than between R or Pc and Pd macrohabitats. This similarity may be associated with greater connectivity between R and Pc macrohabitats. Correspondence analysis indicated that macroinvertebrate composition changed along a gradient from R to Pc and Pd that was related to a perennialintermittent gradient across sites. High variability among macroinvertebrate assemblages in Pd could have been related to variability in the duration of intermittency. In cluster analysis, macroinvertebrate assemblages were grouped by macrohabitat first and then by site, suggesting that the macrohabitat filter had a greater influence on macroinvertebrate assemblages than did local site characteristics. Few taxa were found exclusively in Pc, and this macrohabitat shared numerous taxa with R and Pd, indicating that Pc may act as a bridge between R and Pd during drought. Drought is regarded as a ramp disturbance, but our results suggest that the response of macroinvertebrate assemblages to the loss of hydrological connectivity among macrohabitats is gradual, at least in Mediterranean-climate streams where drying is gradual. However, the changes may be more dramatic in arid and semiarid streams or in Mediterranean-climate streams if drying is rapid.
