Depuis 1953, les Musées royaux d’Art et d’Histoire possèdent quatre tapisseries, illustrant autrefois une Histoire d’Hercule, tissées durant la seconde moitié du XVIe siècle dans l'atelier bruxellois de Frans Schavaert. La découverte de quatre autres pièces, dispersées dans diverses collections privées, a permis à quelques spécialistes de reconsidérer la tenture dans son ensemble. L’objectif de cette communication est de réexaminer cette suite, encore trop souvent méconnue des chercheurs, qui constitue un bel exemple, toujours conservé en Belgique, du style Renaissance dans l’art de la tapisserie bruxelloise. Cette intervention consiste à revoir les aspects iconographique et stylistique de la tenture, à retracer la date du tissage, particulièrement à l’aide des bordures, et à fournir de nouvelles données sur l’œuvre du licier [less ▲]

The purpose of this paper is to list the recent updates of the R package catR. This package allows for generating response patterns under a computerized adaptive testing (CAT) framework with underlying item response theory (IRT) models. Among the most important updates, well-known polytomous IRT models are now supported by catR; several item selection rules have been added; and it is now possible to perform post-hoc simulations. Some functions were also rewritten or withdrawn to improve the usefulness and performances of the package. [less ▲]

PIB ATPases are metal cation pumps that transport metals across membranes. These proteins possess N- and C-terminal cytoplasmic extensions that contain Cys- and His-rich high affinity metal binding domains, which may be involved in metal sensing, metal ion selectivity and/or in regulation of the pump activity. The PIB ATPase HMA4 (Heavy Metal ATPase 4) plays a central role in metal homeostasis in Arabidopsis thaliana and has a key function in zinc and cadmium hypertolerance and hyperaccumulation in the extremophile plant species Arabidopsis halleri. <br />Here, we examined the function and structure of the N-terminal cytoplasmic metal-binding domain of HMA4. We mutagenized a conserved CCTSE metal-binding motif in the domain and assessed the impact of the mutations on protein function and localization in planta, on metal-binding properties in vitro and on protein structure by Nuclear Magnetic Resonance spectroscopy. <br />The two Cys residues of the motif are essential for the function, but not for localization, of HMA4 in planta, whereas the Glu residue is important but not essential. These residues also determine zinc coordination and affinity. Zinc binding to the N-terminal domain is thus crucial for HMA4 protein function, whereas it is not required to maintain the protein structure. <br />Altogether, combining in vivo and in vitro approaches in our study provides insights towards the molecular understanding of metal transport and specificity of metal P-type ATPases.

Si les mécanismes de démocratie participative sont de plus en plus souvent convoqués au cœur de nos systèmes de démocratie représentative (Sintomer, Blondiaux, 2002), devons-nous considérer de facto que le citoyen a une influence dans le processus décisionnel? La participation est-elle le moyen de rendre légitime le rôle et le poids du citoyen dans le processus décisionnel ou a contrario est-elle un moyen supplémentaire pour l’autorité publique de renforcer la légitimité de son action, indépendamment des attentes du citoyen ? Si ce dernier n’était pas légitime, pourrait-il être crédible ? Sur base d’une analyse comparative de cinq conflits d’implantation, nous établirons que, d’une part, l’impératif délibératif (Sintomer, Blondiaux, 2002) est traversé par une logique d’action symbolique envers le citoyen (autrement dit, légitimer le processus par sa présence) et une logique d’intérêts des acteurs, en particulier, l’autorité publique. Confronter à cette double logique, nous proposerons de mettre en exergue les différentes formes d’appropriation de la participation par le citoyen [less ▲]

In this paper, we provide a novel way to estimate the out-of-sample predictive ability of a trading rule. Usually, this ability is estimated using a sample splitting scheme, true out-of-sample data being rarely available. We argue that this method makes a poor use of the available data and creates data mining possibilities. Instead, we introduce an alternative .632 bootstrap approach. This method enables to build in- sample and out-of-sample bootstrap datasets that do not overlap but exhibit the same time dependencies. We show in a simulation study that this technique drastically reduces the mean squared error of the estimated predictive ability. We illustrate our methodology on IBM, MSFT and DJIA stock prices, where we compare 11 trading rules speci cations. For the considered datasets, two different filter rule specifications have the highest out-of-sample mean excess returns. However, all tested rules cannot beat a simple buy-and-hold strategy when trading at a daily frequency. [less ▲]

The wheat germ oil may constitute an alternative to the misuse of this cereal grain resource. The Tunisian exploitation is limited, at present, in the human and animal feed in the grain form, straw or some transformed products. For the purpose of characterization, the wheat germ oil has been extracted by Soxhlet apparatus from a Tunisian variety of durum wheat (Maali) based on the hexane as a solvent. An analysis by gas chromatography (GC) was then performed to identify and quantify the fatty acids of the oil. Then, the oil has submitted to a second chromatography analysis in liquid phase (HPLC) to quantify the tocopherols. The most important fatty acids constituting have been the two polyunsaturated acids linoleic acid C18:2 (OMEGA 6) and the gamma acid- linoleic C18:3 : 58.24 % and 4.19 % respectively; and the acid monounsaturated oleic acid C18:1 ( 24.49 %) but also some saturated acid: palmitic acid C16:0 with ( 19.50 % ), and the stearic acid C18:0 (1.29%). For this variety of Tunisian durum wheat, the wheat germ oil contains, in addition, 80.27 mg / 100g of α- tocopherols (vitamin E). The wheat germ oil extracted from the Tunisian variety 'Maali' has proved rich in vitamin E and omega-6 ; a better valorisation on the nutritional or pharmaceutical plan is to this title recommended.
