Earthworms are known to play integral roles in soils, and are often referred to as vital soil and ecosystem engineers. They have the ability to influence a wide range of chemical, physical, and biological properties of soil environment. In the present study, earthworm and soil samples were collected from wheat cultivated fields in Gembloux, Belgium under four agricultural practices: (1) conventional tillage with crop residues incorporated into the soil (CT/IN); (2) conventional tillage with crop residues exported from the field (CT/OUT); (3) reduced tillage with crop residues incorporated into the soil (RT/IN); and (4) reduced tillage with crop residues exported from the field (RT/OUT). The different agricultural practices were applied on luvisol soil for four consecutive years prior to the initiation of the current study. The purpose of this study was to research the influence of agricultural practices on earthworms with considering species and their interactions with soil properties. Results indicated that agricultural practices affected soil properties and earthworm communities. For each depth, measures of soil physico-chemical properties showed significant differences among treatments. The penetration resistance (PR) measured to a depth of 50 cm increased with increasing soil depth in all treatments. PR was significantly higher in RT compared with CT. Soil moisture was measured before PR determination. Soil samples showed higher P and K concentrations in 0 – 10 cm depth compared with other depths. The main reason for the large K and P accumulation near the soil surface is the incorporation of crop residues. Significant differences were not detected between residue incorporation depth treatments, where results showed mean earthworm abundance was respectively 182 and 180 individuals m-2 in CT and RT. Mean earthworm biomass was similarly not significantly different between CT and RT, where results were respectively 48.5 and 57.3 g.m-2. However, a significant difference was observed between IN and OUT treatments, suggesting the exportation of crop residues will limit earthworm abundance and biomass, and will mask the effect of tillage. The endogeic species Apporectodea caliginosa strongly dominated the earthworm community (64%), whereas epigeic and anecic species remained < 3% and 5% of all earthworms. Findings indicate that endogeic and epi-anecic groups appears to be highly affected by tillage practice and the exportation of crop residues. Consequently, it seems that the effect of residue exportation was stronger than tillage effect. In compacted soils, L. terrestris, L. castaneus and A. caliginosa species showed an increased abundance. The obtained results were attributable to earthworm activity and crop residues, suggesting earthworms contributed to nutrient dynamics and soil structure, particularly at increased soil depths. Overall, the results emphasise the influence of crop residues exportation on earthworm community and also, the important influence of earthworm activity on soil physico-chemical properties change, processes which are closely linked.

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 ▲]

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 ▲]
