Trop d’universités en Belgique ? Après de nombreux débats récurrents sur le sujet, le francophone Décret Bologne du 31 mars 20041 a provoqué un rassemblement des neuf institutions universitaires, appelées à collaborer davantage pour former trois académies. L’académie « Wallonie Bruxelles » regroupant l’Université Libre de Bruxelles (ULB), la Faculté Polytechnique de Mons (FPMs) et l’Université de Mons-Hainaut (UMH), l’académie « Wallonie Europe » regroupant l’Université de Liège (ULg), la Faculté d’agronomie de Gembloux (FUSAGx) et enfin celle de « Louvain » reprenant l’Université Catholique de Louvain (UCL), les Facultés Universitaires Catholiques de Mons (FUCaM), les Facultés de Notre Dame de la Paix (FNDP) et les Facultés Universitaires de Saint Louis (FUSL). Cet article s'intéresse d’une part au processus de négociations menant à la constitution au sein de la Communauté française des «académies » et à la manière dont elles ont évolué par la suite.

Introduction. - Age estimation performances may be influenced by group biases. Objective. - This study investigated whether we are more accurate at estimating the age of people from one's own-age than the age of younger or older people. Method. - Children, young and older adults’ performances at estimating both in-group and out-group faces were compared. Results. - A significant “Age of participants” × “Age of face stimuli” interaction was revealed. Moreover, the age of children's faces was more accurately estimated than the age of young and older adults’ faces by the three groups of participants. Conclusion. - The present results revealed the occurrence of an own-age bias for children, young and older adults in age estimation. Several explanations to this own-age effect are discussed.

Intracranial hypertension is one of the major causes of secondary injury in traumatic brain injury leading to a significant burden of morbidity and mortality. We here present a review of available therapies for the treatment of refractory intracranial hypertension that is defined as an intracranial hypertension that does not respond to the firstline therapies. Second-line therapies that are available for the treatment of refractory intracranial hypertension include mild induced hypothermia, inotropes, and vasopressors for the control of cerebral perfusion pressure, transient hyperventilation, barbiturates, and decompressive craniectomy. Apart from decompressive craniectomy, these therapies are supported by the last guidelines published by the Brain Trauma Foundation (BTF). However, the level of evidence supporting them is low to moderate. This is probably partly explained by the fact that traumatic brain injury is extremely heterogeneous and requires multimodal and individualised care, which makes randomised clinical trials difficult to set up. On-going studies like those conducted on induced hypothermia (EUROTHERM3235) and on decompressive craniectomy (RESCUEicp) may lead to new perspectives for the management of patients suffering from refractory intracranial hypertension.

A method has been designed to test the retention of drops generated by a moving agricultural nozzle using high speed imaging both on synthetic and leaf surfaces. The method allows a precise investigation of spray retention by a characterisation of impact speed, drop diameter and impact behaviour. The paper presents a comparison of the spray behaviour on the synthetic surface with the behaviour on outdoor grown wheat leaves fixed on a microscope slide. Target surfaces were horizontal. A range of surface tension was tested using the tank-mix adjuvant Break-Thru S240 at different concentrations in distilled water. Results show the relevance of a synthetic surface for use as reference for the assessment of spray application efficiency. The drop behaviour on the superhydrophobic slide was representative of difficult-to-wet leaves surfaces. The reference surface avoids the natural variability of leaves and is therefore more suited to conduct comparative assessment of formulation retention performance. [less ▲]

Poly(ε-caprolactone) (PCL) fibers ranging from 250 to 700 nm in diameter were produced by electrospinning a polymer tetrahydrofuran/N,N-dimethylformamide solution. The mechanical properties of the fibrous scaffolds and individual fibers were measured by different methods. The Young’s moduli of the scaffolds were determined using macro-tensile testing equipment, whereas single fibers were mechanically tested using a nanoscale three-point bending method, based on atomic force microscopy and force spectroscopy analyses. The modulus obtained by tensile-testing eight different fiber scaffolds was 3.8 ± 0.8 MPa. Assuming that PCL fibers can be described by the bending model of isotropic materials, a Young’s modulus of 3.7 ± 0.7 GPa was determined for single fibers. The difference of three orders of magnitude observed in the moduli of fiber scaffolds vs. single fibers can be explained by the lacunar and random structure of the scaffolds. [less ▲]

These last few years the multicolored Asian ladybird, Harmonia axyridis (Pallas), previously introduced in Europe and North America as a biological control agent, has swiftly spread out on those territories and turns out to be a pest in several ways. In order to improve understanding of several key points of the biology of this ladybird, a novel fast-GC method of quantification of harmonine, the main defense alkaloid of H. axyridis, has been designed and validated using the accuracy profile concept for concentrations ranging from 13 to 264 µg/individual. This method allows quantifying harmonine in a single insect with a maximal error risk of 20%. For ladybirds collected in spring, mean harmonine concentration observed was 106.6 µg/individual with a very high standard deviation of 80.2 µg/individual, which can easily be explained by the strong asymmetry of the results distribution. Males and females seem equally chemically protected as the harmonine concentration did not significantly differ between sexes. This method is currently used to improve our comprehension of several key points of H. axyridis biology including aggregation behavior and aposematism. [less ▲]

Saffaj et al., recently proposed an uncertainty profile for evaluating the validity of analytical methods using the statistical methodology of γ-confidence β-content tolerance intervals. This profile assesses the validity of the method by comparing the method measurement uncertainty to a pre defined acceptance limit stating the maximum uncertainty suitable for the method under study. Several years earlier as stated by these authors a SFSTP (Société Française des Sciences et Techniques Pharmaceutique) commission has developed a similar profile called accuracy profile used to assess the validity of analytical methods. This accuracy profile also uses the methodology of statistical tolerance intervals, but β-expectation tolerance intervals. The uncertainty profile of Saffaj et al. and the accuracy profile of the SFSTP commission are both fulfilling the same final purpose. The core question is finally what statistical tolerance interval to use ? The aim of this letter to the editor is to discuss this question and provide arguments that β-expectation tolerance intervals should be prefered to assess the validity of the method as this type of interval give the guarantee that each future results has high probability to fall within pre-specified acceptance limits.

A l'heure actuelle, il existe relativement peu de recherches qui traitent du système de contrôle de gestion des PME, spécialement dans le contexte tunisien, malgré leur importance économique. La présente communication vise dès lors à élaborer un modèle théorique expliquant le design du système de contrôle de gestion dans les PMI tunisiennes, au départ d'une analyse de la littérature portant spécifiquement soit sur les PMI tunisiennes, soit sur le système de contrôle de gestion de la PME. Cette étude est réalisée en privilégiant deux angles d'analyse particulièrement importants au vu du contexte tunisien, à savoir la taille de l'entreprise et son positionnement sur le cycle de vie.
