Cet article est basé sur un inventaire des bonnes pratiques en gestion de la diversité dans le secteur public en Belgique, et dans quelques pays européens (plus de 100 pratiques recensées et décrites), réalisé, en collaboration avec une autre équipe universitaire, pour la cellule diversité du service des ressources humaines de l’administration fédérale. L’objectif de cet inventaire était de réaliser un manuel et d’offrir un outil de travail aux responsables diversité des institutions fédérales belges et, plus largement, à tout acteur impliqué dans des projets visant à valoriser la diversité dans l’emploi dans le secteur public. Cet inventaire comprenait un contact une personne de contact connaissant la pratique pour identifier, outre la description de la pratique et des parties prenantes impliquées, les difficultés rencontrées et les facteurs de succès. Cet inventaire a permis de mettre en évidence le large éventail des pratiques mais aussi les composantes organisationnelles de la gestion de la diversité et les difficultés spécifiques au secteur public.

In addition to providing lipid chains for protein prenylation, short-chain isoprenyl diphosphate synthases (scIPPSs) play a pivotal role in the biosynthesis of numerous mevalonate pathway end-products, including insect juvenile hormone and terpenoid pheromones. For this reason, they are being considered as targets for pesticide development. Recently, we characterized an aphid scIPPS displaying dual geranyl diphosphate (GPP; C10)/farnesyl diphosphate (FPP; C15) synthase activity in vitro. To identify the mechanism(s) responsible for this dual activity, we assessed the product selectivity of aphid scIPPSs bearing mutations at Gln107 and/or Leu110, the fourth and first residue upstream from the “first aspartate-rich motif” (FARM), respectively. All but one resulted in significant changes in product chain-length selectivity, effectively increasing the production of either GPP (Q107E, L110W) or FPP (Q107F, Q107F–L110A); the other mutation (L110A) abolished activity. Although some of these effects could be attributed to changes in steric hindrance within the catalytic cavity, molecular dynamics simulations identified other contributing factors, including residue-ligand Van der Waals interactions and the formation of hydrogen bonds or salt bridges between Gln107 and other residues across the catalytic cavity, which constitutes a novel product chain-length determination mechanism for scIPPSs. Thus the aphid enzyme apparently evolved to maintain the capacity to produce both GPP and FPP through a balance between these mechanisms. [less ▲]

This paper reports on prospective tests of a system protection scheme against long-term voltage instability relying on a set of distributed controllers, each monitoring a transmission voltage, blocking tap changers and shedding loads in a zone. The emergency actions adjust in magnitude and location to the disturbance. Each controller acts in closed-loop, which guarantees robustness. The method is illustrated on a real-life model of the Western region of the RTE system. The choice of the controller settings is discussed in some detail and examples of performance are given, combining the above remedial action with capacitor switching and secondary voltage control.

A number of recent authors have emphasised the increasing disconnection from conservation issues among urban dwellers. In a global increase of urbanisation, this disconnect can have an impact on conservation practices. Here, we discuss how managers of public green spaces can contribute to global biodiversity preservation, through combined efforts to preserve local biodiversity and educate the public about conservation issues. We compared several management strategies, including those that mixed direct action on local biodiversity with public education and those that did not. Two kinds of one-way communication were considered as well as a two-way communication process, which take into account different perceptions and practices of nature. We based our model on the introduction of the red-eared slider turtle, Trachemys scripta elegans, into urban French freshwater ecosystems. We found that direct actions only had a limited, short term effect on the abundance of feral turtles in green spaces and had no effect on the level of public concern about environmental questions. We also showed that a mix of different communication strategies improved people’s awareness and altered behaviour with respect to introduced species issues. Finally, we showed the importance of a two-way communication that takes into account the diversity of personal perceptions and practices as regards nature in urban areas in order to achieve sustainable conservation measures and objectives [less ▲]

Dans le cadre de la conception d’un espace immersif multimodal visant à soutenir la tâche d’évaluation de la qualité acoustique de salles sur base de simulations numériques, nous nous intéressons aux liens entre l’image et le son. 54 sujets ont été confrontés à une tâche de jugement du degré de réverbération d’un extrait sonore dans une situation contrôle (sans image) puis dans une situation expérimentale avec, pour la moitié des sujets, une image visant à soutenir le jugement (cohérente avec le son) et, pour l’autre moitié, une image « distractrice ». Nos résultats montrent une influence positive des images évocatrices et pas d’effet des images distractrice. [less ▲]

Magnetic shielding efficiency was measured on high- Tc superconducting hollow cylinders subjected to either an axial or a transverse magnetic field in a large range of field sweep rates, dBapp/dt. The behaviour of the superconductor was modelled in order to reproduce the main features of the field penetration curves by using a minimum number of free parameters suitable for both magnetic field orientations. The field penetration measurements were carried out on Pb-doped Bi-2223 tubes at 77 K by applying linearly increasing magnetic fields with a constant sweep rate ranging between 10 uT s[?]1 and 10 mT s[?]1 for both directions of the applied magnetic field. The experimental curves of the internal field versus the applied field, Bin(Bapp), show that, at a given sweep rate, the magnetic field for which the penetration occurs, Blim, is lower for the transverse configuration than for the axial configuration. A power law dependence with large exponent, n', is found between Blim and dBapp/dt. The values of n' are nearly the same for both configurations. We show that the main features of the curves Bin(Bapp) can be reproduced using a simple 2D model, based on the method of Brandt, involving a E(J) power law with an n-exponent and a field-dependent critical current density, Jc(B), (following the Kim model: Jc = Jc0(1+B/B1)[?]1). In particular, a linear relationship between the measured n'-exponents and the n-exponent of the E(J) power law is suggested by taking into account the field dependence of the critical current density. Differences between the axial and the transverse shielding properties can be simply attributed to demagnetizing fields. [less ▲]

The present informal document summarises recent or ongoing studies conducted at Liège University in the field of steel-concrete composite constructions; they are summarised in a Table presented at the following page. Only the main results are presented herein. For all the addressed topics, references to documents, reports and articles where details are available will be made; a copy of these documents can be obtained by contacting us. At the end of each paragraph, a section dedicated to some perspectives is given. § 9.2 summarises the main topics in which investigations could be conducted in the future; these perspectives are also reported in the Table here after. The activities related to the response of composite structures subjected to seismic or fire actions (mainly covered in Liège by Prof. Plumier and Prof. Franssen respectively) are not reported here as they are covered by other more “transversal” technical committees of ECCS (TC3 for the fire and TC13 for the seismic action). The “composite joints” topic is included here even if a technical committee relative to the behaviour of joints exists within ECCS (TC10); indeed, in the past, all the developments relative to composite joints were discussed and accepted within TC11 and not within TC10. Of course, it is up to the present TC11 members to decide whether this topic has or not to be considered within TC11. Finally, the robustness of composite structures and in particular, the robustness of the structures subjected to the exceptional event “loss of a column further” is also considered herein as this topic is not yet covered by any other technical committee. Again, it is up to the TC11 members to decide whether this topic has to be discussed within TC11. [less ▲]
