Avec les avenues qu’offre le Web2.0, le processus d’évaluation des apprentissages en éducation/formation pourrait subir des transformations auxquelles on n’osait penser il y a très peu de temps. Il est ainsi fort possible que la contribution humaine à ce processus soit toute autre que celle que les étudiants du XXe siècle ont connue. Mais ces transformations à venir du processus d’évaluation et de ses objets signifient-elles qu’il y aura un prix à payer en termes de validité et de fidélité ? Ainsi, l’entrée en jeu de nouveaux outils pour observer et recueillir des données sur les compétences développées pose des défis particuliers parce que dans une approche par compétence ce qui doit être évalué diffère passablement de ce qui est valorisé lorsque les seules connaissances sont visées. L’effervescence observée à cet égard est ainsi une bonne occasion pour faire le point sur ce qu’il est possible de faire pour évaluer des compétences en utilisant l’ordinateur (i.e. les TIC) et sur la validité et la fidélité du processus d’évaluation dans ce contexte.

Cet article constitue une synthèse sur la forêt de tapia (Uapaca bojeri Baill.) de Madagascar en vue de présenter son importance dans le développement de la communauté riveraine via l’amélioration des revenus par ménage. La forêt de tapia est une formation « socio-naturelle », à strate arborée quasi monospécifique et endémique de Madagascar. Elle est localisée uniquement dans les hautes terres malgaches. À part les fonctions écosystémiques, la forêt de tapia abrite différentes ressources naturelles, entre autres les produits forestiers non ligneux et ligneux, qui jouent un rôle important dans l’économie locale informelle. Toutefois, cette formation végétale est menacée par la destruction humaine à travers les feux de brousse, la production de bois de chauffe et de charbon de bois, l’extension de l’agriculture et l’envahissement par des espèces exotiques de reboisement. Subséquemment, la gestion durable et la protection de cette forêt sont essentielles afin que les populations riveraines puissent en profiter de génération en génération [less ▲]

The authors recently observed two patients who suffered acute lower limb ischemia secondary to thrombosis of a small (diameter of less than 2 cm) popliteal artery aneurysm. A literature search lead to the conclusion that small popliteal aneurysms, covered with mural thrombus and presenting a distorted neck due to elongation, are prone to thrombosis. Another risk factor is a restrained outflow bed as a result of previous micro-embolisations into the tibial arteries. The authors conclude that small popliteal artery aneurysms are not so innocent as is often presumed. [less ▲]

Objective: The European Organisation for the Research and Treatment of Cancer (EORTC) Radiation Oncology Group (ROG) has performed radiotherapy quality assurance (QA) in clinical trials, including dummy runs (DR) and individual case reviews (ICR), since 1991. We investigated the influence of DR results on subsequent QA and patient outcomes. Methods: EORTC ROG studies were reviewed for DR inclusion, QA and mature clinical outcomes. A DR was classified as a failure if corrections necessitated re-submission. ICR were graded as acceptable, minor or major deviation overall. Fisher's exact test characterised potential correlations and the Mantel-Haenszel statistic quantified pooled odds ratios (OR). Results: DR and ICR data were available from 12 and 3 protocols, respectively. The proportion of institutions successful at first DR attempt varied per trial from 5.6% to 68.8%. Participants were 3.2 times more likely to pass at first attempt after previous DR participation (p = 0.0002). Pooled OR for an acceptable ICR was 1.69 (p = 0.06) for institutions successful at DR first attempt. The effect of DR participation was not significantly correlated with patient outcome in the trial available for analysis. Conclusions: Implementing QA measures in ROG clinical trials should ensure optimal radiotherapy delivery. Centres which previously participated in a DR were significantly more likely to be successful at subsequent QA procedures. © 2012 Elsevier Ltd. All rights reserved. [less ▲]

This paper presents a new way to design innovative Building Construction System[BCS]. The BCS is defined as a set of technical specifications of a pre- engineered building. The interest of the use of a BCS is to reuse the same specifications in several building constructions. These specifications can than be studied in more detail with higher design budgets. [less ▲]

Second-generation antipsychotics (SGA), especially clozapine and olanzapine, are associated with an increased metabolic risk. Recent research showed that plasma adiponectin levels, an adipocyte-derived hormone that increases insulin sensitivity, vary in the same way in schizophrenic patients as in the general population according to gender, adiposity and metabolic syndrome (MetS). The aim of the present study was to investigate whether different SGAs differentially affect plasma adiponectin levels independent of body mass index (BMI) and MetS status. 113 patients with schizophrenia (65.5% males, 32.3years old) who were free of antipsychotic medication were enrolled in this open-label prospective single-center study and received either risperidone (n=54) or olanzapine (n=59). They were followed prospectively for 12weeks. Average daily dose was 4.4mg/day for risperidone and 17.4mg/day for olanzapine. Plasma adiponectin levels as well as fasting metabolic parameters were measured at baseline, 6weeks and 12weeks. The two groups had similar baseline demographic and metabolic characteristics. A significant increase in body weight was observed over time. This increase was significantly larger in the olanzapine group than in the risperidone group (+7.0kg versus +3.1kg, p<0.0002). Changes in fasting glucose and insulin levels and in HOMA-IR, an index of insulin resistance, were not significantly different in both treatment groups. MetS prevalence increased significantly more in the olanzapine group as compared to the risperidone groups where the prevalence did not change over time. We observed a significant (p=0.0015) treatment by time interaction showing an adiponectin increase in the risperidone-treated patients (from 10,154 to 11,124ng/ml) whereas adiponectin levels decreased in olanzapine treated patients (from 11,280 to 8988ng/ml). This effect was independent of BMI and the presence/absence of MetS. The differential effect of antipsychotic treatment (risperidone versus olanzapine) on plasma adiponectin levels over time, independent of changes in waist circumference and antipsychotic dosing, suggests a specific effect on adipose tissues, similar to what has been observed in animal models. The observed olanzapine-associated reduction in plasma adiponectin levels may at least partially contribute to the increased metabolic risk of olanzapine compared to risperidone. [less ▲]

One of the greatest success stories in our societies is that people are living longer, life expectancy at birth being now above 80 years. Whereas the lengthening of life opens huge opportunities for individuals if extra years are spent in prosperity and good health, it is however often regarded as a source of problems for policy-makers. The goal of this paper is to examine the key policy challenges raised by increasing longevity. For that purpose, we first pay attention to the representation of individual preferences, and to the normative foundations of the economy, and, then, we consider the challenges raised for the design of the social security system, pension policies, preventive health policies, the provision of long term care, as well as for long-run economic growth.

The aggregative behaviour of the multicoloured Asian ladybeetle, Harmonia axyridis Pallas, during winters, is still misunderstood. Our study was focused on the chemical and physical factors involved in the selection of its aggregation sites. Chemical and behavioural analyses highlighted that long-chain hydrocarbons lead congeners towards aggregations and ensure the cohesion of the cluster. On the other hand, we investigated the influence of (1) the density of individuals and (2) the quality of available shelters on H. axyridis decision to settle and aggregate under shelters. A binary choice experiment conducted in laboratory highlighted a permanent aggregative behaviour of H. axyridis, even during non-wintering conditions, and the existence of social interactions between individuals.

Standard toxicological assays using the zebrafish model system evaluate lethality and teratogenicity upon exposure during the first two days after fertilization. We tested the biological effects of several widely used drugs on zebrafish by acute treatment for 24hours starting at late embryonic stages, between 48 and 72hours post-fertilization. For 4 out of 6 compounds, we observed a higher sensitivity of late stage zebrafish embryos for general toxicity (lethality) compared to younger embryos. Morphological defects such as edema, body curvature, delayed growth, decreased heart rate and locomotion were observed for each of the compounds tested, often at sublethal concentrations. Gene expression studies on a set of four selected genes revealed a specific regulatory pattern for the different compounds tested. Our results allow us to compare various toxicological endpoints and may contribute to the design of a rational high throughput approach using the zebrafish model. [less ▲]
