The aim of this work is to present the spatial organization of the six Walloon clusters. Their spatial structure is considered under two approaches: first the proximity question between the actors of R&D projects and then the question of Walloon territorial division. The methodology rests on statistics and cartography of the localization of clusters actors. The results reveal the competitive area of Wallonia and the weight of geographic proximity between the actors of innovative projects. [less ▲]

Nests supports are made atractive on a high-perched position as far as the Spanish sparrow is concerned. Such supports should be closely-packed, provided with a plethora of sprigs and located near cereal fields. The breeding colonies of early clutches that gather several thousands of birds in Orania are comparatively independant of aquatic areas. High density nest zones within a colony of birds seem to be related not only to the supports themselves but also to the diversified vegetal environment. Simultaneous species reproduction in the Oran area is carried out in each region accordingly. Futhermore, results reveal that the reproduction may be of itinerant character, therefore tallying with Ward's assumption that among seed-eating species living in semi-arid zones, the Red-billed quelea cannot de regarded as the solely itinerant breeder. Although clutch size can vary from various sectors within the framework of a colony, homogeneity is maintained inside the region itself. However, the number of young fledged can be otherwise. On the other hand, few sparrows will exceed one single clutch in seasonal dry weather in the surveyed area. Discussions on the various results obtained are mainly looked upon in line with space/time fluctuations of the food supply and parental behaviour. In other respects, heterogeneity of brood success indicate that the Spanish sparrow has no apparent mechanism for colony-size regulation. While nests are being built, colony-size however can be relevant to habitat restraints. Attempts at giving theorical model of the foregoing are still being made. [less ▲]

Toutes les organisations de commerce équitable (OCE) ont en commun d’être confrontées aux tensions traversant l’ensemble du mouvement équitable, entre une logique de solidarité et une logique de marché. Ce qui différencie les OCE, c’est la manière de gérer cette tension et de se positionner par rapport à ces différentes logiques. L’objectif de cette contribution est d’éclairer ces différents positionnements à travers l’étude des objectifs organisationnels, des ressources, du statut juridique et des instances de gouvernance des OCE. Nous commençons par présenter la grille théorique qui introduit ces différents indicateurs organisationnels. Ensuite, nous proposons quatre scénarios possibles (et empiriquement observés) de gestion des tensions : le scénario commercial, le scénario socio-politique, le scénario intégratif et le scénario de dédoublement. Ces scénarios sont illustrés par des exemples d’OCE du Nord. Enfin, après une synthèse de ces quatre scénarios, nous nous penchons sur leurs implications sur l’avenir du mouvement équitable.

The continuing education is a challenge for health care professionals, considering the growing amount and variable quality of information in this field. In this context, we developed a method allowing clinicians to have a centralised access to the best current medical evidence supporting medical decision-making. Relevant data has been gathered according to the rules stated for Evidence-Based Medicine (EBM) and organised in a free-of-charge Web site, created by using common software applications. The general aim of our study was to encourage individual practice of EBM by providing tutorials as well as a selection of free access tools for searching medical information on the Web. In addition to the education part, we provided clinicians, through a Web interface, with up-to-date, accurate and quality data obtained from heterogeneous sources and presented in a full text format when available. The developed methodology has been applied to human prostate cancer. URL address: http://www.ebm.lib.ulg.ac.be/prostate/index.htm. (C) 2002 Elsevier Science Ireland Ltd. All rights reserved.

Posidonia oceanica is a seagrass endemic to the Mediterranean Sea, and is able to form large monospecific areas, called meadows. These meadows shelter high biomasses and biodiversities of amphipod crustaceans. Moreover, It is now established that several species of these amphipods feed on the macro-epiphytes present on the leaves of the seagrass. Here, we performed in situ experiments to assess whether this grazing activity could impact the dynamics of the leaves’ epiphytic cover, and thus influence the functioning of the meadow as an ecosystem. We used microcosms containing monospecific populations of 3 amphipods taxa (Apherusa chiereghinii, Dexamine spiniventris and Gammarus spp.), and placed them directly in the meadow, at a depth of 10m. Biomasses of erected macroalgae and erected animals (hydrozoans, bryozoans) were lower in all grazed treatments. However, none of the studied taxa seemed to consume encrusting epiphytes, either vegetal or animal. This selective grazing pressure by amphipods may release encrusting epiphytes from competition for space, light and/or nutriments with the fast-growing erected algae, and could thus play an important role in the structuring of the epiphytic cover from P. oceanica leaves. Moreover, this top-down control might keep erected algae biomass to a normal, sustainable level, therefore also benefiting the seagrass itself. Our results also indicate that amphipod trophic activity caused nitrogen enrichment in both grazed (erected algae) and non-grazed (encrusting algae & seagrass leaves) vegetal tissues. A plausible interpretation could be that sloppy feeding and excretion by the grazers enhanced availability of this nutrient, which is typically limiting for photosynthesis in shallow P. oceanica meadows. This emphasizes the fact that grazing is not a simple negative interaction, but that it can also benefit the primary producers. Our results thus indicate that amphipods from P. oceanica meadows seem to be bound to the epiphytic cover of the leaves by complex and multilateral trophic interactions, and have an indirect influence on the seagrass itself. Amphipods may therefore play an important part in the functioning of the epiphyte/seagrass/grazer system of these meadows, and thus act as ecosystems engineers. This abstract is dedicated to the freshly born Adèle and Côme. [less ▲]

In quail, the hypothalamus enzymatically transforms testosterone (T) into estradiol (E2), 5 alpha-dihydrotestosterone (5 alpha-DHT), and 5 beta-dihydrotestosterone (5 beta-DHT). During the embryonic life, the 5 beta-reductase activity is very high, which probably protects the brain of males from being behaviorally demasculinized by their endogenous T. 5 beta androstanes are inactive androgens. The decrease of 5 beta reductase with age during sexual maturation corresponds to a potentiation of the effects of T as shown by experiments that compared the effects of T and 5 alpha-DHT in adult and young quail. T metabolism is also involved in the activation of male behavior in the adult. T aromatization is probably essential for behavioral activation, but nonaromatizable androgens such as methyltrienolone, and to some extent 5 alpha-DHT, can also stimulate sexual behavior in castrates. These enzymatic activities show a clear neuroanatomical localization and are sexually dimorphic. Males produce more active metabolites (E2, 5 alpha-DHT) than females, which could explain the male's greater sensitivity to T treatments. It thus appears that T metabolism is involved in the differentiation and activation of behavior in quail. [less ▲]
