Les insectes communiquent avec leurs semblables et avec leur environnement par le biais de molécules organiques informatives nommées sémiochimiques. L'écologie chimique est la branche de l'écologie qui s'intéresse au décriptage de ce mode de communication, dont le maitre d'œuvre est le système olfactif des insectes, où antennes et sensilles supportent toute la machinerie physiologique nécessaire à la perception des phéromones et coactones. Pour comprendre le language chimique employé par un insecte, de nombreux outils ont été développés, permettant (1) l'échantillonnage des molécules organiques produites par un insecte, (2) la séparation, la quantification et l'identification des différents constituants du mélange phéromonal,(3) l'étude de la perception par le système olfactif de l'insecte et (4) l'étude du comportement d'un individu mis en présence d'un potentiel bouquet phéromonal ou de l'un de ses constituants. De nombreuses phéromones et coactones ont déjà trouvé le chemin de la valorisation dans le domaine de la protection des cultures. Bien que les insectes d'intérêt agronomique soient les plus largement étudiés, les sémiochimiques employés par d'autres groupes d'insectes font l'objet de nouvelles recherches, avec notamment l'émergence de l'entomologie criminelle [less ▲]

Le problème de la violence résume pour ainsi dire l’œuvre de Jean-Paul Sartre. Il circonscrit souvent, en tout cas, les critiques qu’on lui adresse et, de façon fondamentale, la manière même dont on la lit. L’objet de cette communication sera de reprendre ce problème chez le dernier Sartre, de 1957 à 1973, c’est-à-dire de Questions de méthode à L’Idiot de la famille, à partir d’une analyse serrée de certaines interventions de Sartre sur le terrain politique ou plutôt juridico-politique. Je m’appuierai en particulier sur trois sources : l’intervention de Sartre au procès Ben Saddok (1957), sa préface aux Maos en France (1970) et sa conférence « Justice et État » (1973). Je souhaite mettre en évidence le travail d’élucidation politique que Sartre déploie à cette époque dans le cadre judiciaire, qu’il s’agisse de justice d’État ou de justice populaire. Chez Sartre, ce travail d’élucidation est inséparablement philosophique et littéraire. Il passe ainsi, d’une part, par un usage spécifique de la phénoménologie, dont Sartre a donné le programme dans son Esquisse d’une théorie des émotions, en une référence explicite à l’ontologie fondamentale de Heidegger ; il passe, d’autre part, par une reprise critique (philosophique et politique) de certaines références littéraires, en particulier de Malraux et de Camus dans le premier texte cité. L’Idiot de la famille propose la synthèse de cet effort : de faire de l’émotion une méthode (et non pas simplement d’explorer méthodiquement les émotions) et d’imprimer une torsion politique à la pratique littéraire (et non pas simplement d’y renoncer). À cette double condition, il peut être utile aujourd’hui de chercher, dans la philosophie de Sartre, certains moyens d’une heuristique de la violence et certains outils d’intelligibilité de ce qui, en dernière analyse, renvoie à la question de la liberté, autrement dit encore aux déterminations les plus fondamentales du partage entre puissance et impuissance.

Je voudrais ici tester l’hypothèse suivante : si le champ d’étude de l’image populaire (familiale) s’est vu parfois négliger par les théoriciens, peut-être est-ce à cause de l’écart radical que la photographie spécialisée, et en particulier la photographie artistique, a voulu établir entre elle et la photographie dite « domestique ». Comment (c’est-à-dire par quels moyens, théoriques ou artistiques) une certaine pratique de la photographie s’est-elle aujourd’hui instituée comme un art à part entière ? Plutôt et surtout : comment la noble pratique de la photographie a-t-elle réussi à prendre ses distances avec la photographie commune, pourtant omniprésente, jusqu’à l’évacuer presque totalement des préoccupations scientifiques ? Car il faut bien voir le paradoxe qui sous-tend ce problème : comment est-on parvenu à assigner à l’image commune (pourtant franchement majoritaire) un rôle aussi périphérique ? La place occupée par la photographie domestique dans les théories de la photographie reste incertaine. Quand elle n’est pas purement et simplement évacuée, l’image commune peut soit être « utilisée » pour porter un sens auquel elle ne prétendait pas, soit être prise en compte pour se voir aussitôt réduite à un stéréotype ; son caractère esthétique est dévalué, son style réduit à un non-style. En tenant à distance la culture la plus populaire, on agrandit certainement le gouffre qui sépare le théoricien des expériences vécues (des expériences sensibles). [less ▲]

Performance evaluation presents two specific difficulties for social enterprises. At the one hand, it is complex to define what performance is, to measure the factors impacting performance through indicators, and to sum up the scores of all the indicators. At the other hand, performance evaluation should vary with the purpose of the evaluation and the type of organization. Thus the characteristics of an ideal performance evaluation tool for social enterprises should both reflect this complexity and be contingent. [less ▲]

Emerging concerns about competitiveness induce a growing number of firms to outsource their outbound transportation operations to third-party logistics providers. The resulting increase in the number of actors often leads to sub-optimal supply chain actions due to the antagonistic nature of the economic objectives of the partners. With the aim of determining possible deviations from the optimal system performance in such supply chains, this study analyzes the contractual relation between a retailer and a third-party logistics provider (carrier) using game theoretical approaches. The partners of the studied supply chain play a Stackelberg game in which the retailer is the leader and the carrier is the follower. The retailer faces an uncertain demand and needs to supply his store from his warehouse. he has the option of not meeting all the demand but must satisfy at least a minimum proportion of the fi nall demand. On the other hand, the carrier has to determine the number of trucks needed to satisfy this demand before uncertainty is resolved. Once demand is realized, if the reserved transportation capacity is insufficient, the carrier also has the possibility to requisition trucks at a higher price. We modelise the problem and propose a contract having two parameters : the quantity of transported items and the number of truck used. In our settings, the retailer is the one that submits the contract and the carrier decides if he accepts it or not. We compare this situation with a centralized model where a single decision maker takes all the decisions. [less ▲]

The Design Space (DS) is defined as the set of factors settings (input conditions) that will provide results at least better than pre-defined acceptance limits. The proposed methodology aims at identifying a region in the space of factors that will likely provide satisfactory results during the future use of an analytical method or process in routine, through an optimization process. In a Bayesian framework, the responses are modelled using a multivariate multiple regression model allowing deriving their joint predictive posterior distribution. On the basis of this consequent distribution, a multi-criteria risk-based decision is taken with respect to the pre-defined acceptance limits. This aims to identify the DS. In this context, desirability methodologies are also applied to take the risk-based decision in a more flexible way. An example based on high-performance liquid chromatography illustrates the applicability of the methodology with highly correlated and constrained responses. [less ▲]

In a Model-Based Drug Development strategy, the first objective is to design studies such that the most reliable model estimates are obtained, in order to optimize the design of future studies and to take decisions based on predictions. The objectives of the work is to present from a theoretical and practical point of view how to perform trial predictions, as opposed to trial simulations, by integrating the uncertainty of the parameters. The difference between prediction and simulation is important in early development when limited data or prior information are available. Indeed ignoring the uncertainty of parameter estimates can lead to wrong decisions. First, will be provided methodology, derived from Bayesian statistics, to perform trial predictions from the parameter estimates and their uncertainty, when obtained with conventional frequentist population methods. Second, a practical implementation in R will be shown. This generalized prediction shell can cope with any kind of structural population models: Ordinary Differential Equation, single & multiple doses, infusion, etc... The proposed shell is also flexible to allow the testing of various scenarios and study designs, and therefore evaluate the predictive probability of success of different protocols. When joint models for efficacy and safety are established, the Prediction-based Clinical Utility Index (p-CUI) and its distribution can directly be obtained for more riskless decision making. Examples will be shown to highlight in early phases the differences existing between trial prediction and trial simulation. This approach is required to permit Model-Based Drug Development strategy, and impact successfully decision in early clinical phases. [less ▲]

The LIMA index conveys the environmental interest and quality of the landscape formed by the Mediterranean benthos, ranging from 0 to -40 m, in numerical format. The LIMA index allows a comparison spatially and temporarily between sites. It is a comprehensive index which is easy to implement and is composed of two factors: a topographical description (classification of 15 typologies) and a biological description (the presence or absence of some thirty species or groups of structuring, remarkable and invasive species). The LIMA index has been validated in the Bay of Calvi (Corsica-France) where it varies between 0.31 and 0.79 on a scale of 0.00 to 1.00. [less ▲]

The human-macaque interface in Asia is increasingly the focus of numerous studies raising the issue of conflict over space and resources and searching for efficient management strategies. Documenting impacts of interactions with humans and the variations in macaques’ responses to anthropogenic habitats is essential for undertanding adaptation strategies and possibilities of a sustainable coexistence. The long-tailed macaque (Macaca fascicularis) is a very successful commensal species that adapts remarkably well to rural and urban landscapes. In some locations of Bali (Indonesia), this species, which has coexisted with humans for centuries, is used today to promote wildlife-based tourism, often characterized by an intense food provisioning. Here, we present data of a commensal M. fascicularis population in Bali (Uluwatu Temple), particularly well-habituated to human presence and provisioned daily. We analyze the impacts of the daily variations of three anthropogenic factors (microhabitat – human presence degree – food provisioning quantity) on the daily activity, ranging and dietary patterns. We used a focal and scan sampling methodology during a four-month study period between June and October 2010. Four groups constituted this population and their home ranges were particularly small, ranging from 2.4 to 5.6 ha. The eco-behavioural patterns were strongly and consistently influenced by variations in the anthropic factors. Typically, with a high anthropic level (defined as increasing degrees of each anthropogenic factor), macaques spent less time foraging and moving and more time feeding, resting and socializing. Contrary to previous studies on other primate species, we did not find any impact of provisioning on agonistic interactions. 55% of this population’s diet consisted of human foods, while the remainder (45%) of natural foods. Natural food items were preferentially consumed when anthropic level was low, emphasizing the opportunistic style of the diet. In summary, the eco-behavioural modifications induced by variations in anthropic levels did not increase the daily costs of living, confirming the flexibility and the efficiency of the macaques’ responses. However, we also illustrate in another study site (Ubud – Bali) the risk of overpopulation caused by the provisioning, which may potentially increase the human-macaque conflict. [less ▲]

Social Networking Sites (SNS) provide a new platform for consumer/brand interaction on the Internet. On SNS, firms have the opportunity to create and manage a “brand page” in order to interact with SNS members. Brand pages allow interaction between the members of the page, as well as interaction between the members and the brand, namely brand tribalism and brand relationship. This paper investigates the functioning of SNS as a new platform for brand communities, integrating both consumer-brand relationship and brand communities. More specifically, we aim to understand the impact of brand-managed communities embedded in SNS on brand page commitment and brand commitment. Results show that members’ freedom of expression and recognition for contribution on the brand page impact positively brand pages commitment, which in turn impacts brand commitment. Consequently, brand commitment influences the members’ intention to generate positive word-of-mouth about the brand and willingness to engage in co-production. [less ▲]

Massive stars are characterized by a large radiation over gaz pressure ratio and a large temperature over density ratio. With increasing stellar initial mass, they suffer stronger stellar winds which plays an important role in the chemical enrichment of the galaxies. The induced mass loss affects also the evolution and internal structure of massive stars on the main sequence (MS) and on the post-main sequence phase (post-MS). Recent ground-based observations and space missions have shown the presence of pulsations in massive stars, such as accouctic and gravity modes excited by the $\kappa$-mechanism and even solar-like oscillations. Strange modes could also found to be excited in the most massive stars. $\kappa$-mechanism instability domains are presented for the upper HR diagram (up to $70$M$_{odot}$) on the MS and on the post-MS. We compute evolutionary tracks and non-adiabatic frequencies for different input parameters such as the metallicity, the mass loss rate and the overshooting parameter. [less ▲]

Most of the IPCC-AR4 Atmospheric Global Circulation Models (AGCM) predict an increase of the Antarctic Surface Mass Balance (SMB) during the 21st century that would mitigate global sea level rise. Present accumulation and predicted change are largest at the ice sheet margins because they are driven by snowfall, which mostly comes from warm, moist air arising over the land slopes. The coastal belt is also where complex processes of sublimation, melt and redistribution by the wind occur. Thus, high-resolution modelling (5 to 15 km) is necessary to adequately capture the effects of small-scale variations in topography on the atmospheric variables in this area, but limitations in computing resources prevent such resolution at the scale of Antarctica in full climate models. We present here a downscaling method leading to 15-km SMB resolution for century time-scales over Antarctica. We compute precipitation fields by considering orographic processes induced by the broad-scale and the fine-scale topography, and we estimate sublimation, melting and refreezing with a surface scheme validated for snow and ice-covered land surface. We display the SMB downscaled from LMDZ4 AGCM outputs (~60-km resolution), and compare the agreement of the broad-scale SMB and the downscaled SMB with 20th century observations. Then, we present hi-resolution features of the Antarctic SMB evolution during the 21st century downscaled from LMDZ4 and discuss the effect of the resolution on the Antarctic SMB contribution to sea level change. The downscaling model is a powerful tool that will be applied to others climate models for a better assessment of future sea level rise. [less ▲]

This study is an investigation of the impact of brand pages on Social Networking Sites (SNS) in the creation of brand commitment. The main determinants of brand page commitment are evaluated before assessing its impact on brand commitment. Subsequently, some of the potential consequences of brand commitment are assessed. The empirical part of the study was conducted in collaboration with Netlog, the first European SNS. A questionnaire assessing the 9 variables of the model was answered by a sample of 250 Netlogers. The results show that the main determinants of brand page commitment are the freedom to express on the brand page and the recognition for contributing to it. Furthermore, the study revealed a favorable impact of brand page commitment on brand commitment. The two validated consequences of brand commitment in such a context are the intention to generate positive word-of-mouth about the brand and the willingness to co-produce. [less ▲]

Aurora on giant planets present many differences with the terrestrial aurora and the satellite footprints are among the most striking examples. Created by the interaction between the moons and the magnetospheric plasma, these auroral features are observed as spots or curtains located close to the field lines connecting the satellites to the planet. On Jupiter, the footprints of Io, Europa, and Ganymede have been discovered from ground observations in the infrared domain, Hubble Space Telescope observations in the ultraviolet domain, and Galileo spacecraft images in the visible domain. On Saturn, recent observations from the Cassini spacecraft tentatively identified the UV footprint of Enceladus. First we will briefly review the mechanisms driving these electro-magnetic interactions and their related observational evidences. Then we will discuss the characteristics of these various footprints, focusing on the better-studied cases of the Io and Ganymede footprints. We will see that the analysis of the footprint morphology, location, spatial extent, and brightness provides extremely valuable information both on the planetary magnetic field topology and on the processes at play in the interaction. And these processes are not so different from those creating some components of the Earth aurora. [less ▲]

Polychlorinated biphenyls (PCBs) and organochlorine pesticides like Dichloro-Diphenyl-Trichloroethane (DDTs), Hexachlorocyclohexanes (HCHs), aldrin, dieldrin and trace elements (Cd, Cu, Se, Pb, Zn and Hg) were analysed in the muscle of sea bass (Dicentrarchus labrax) sampled in coastal regions near several important European river mouths (Gironde, Charente, Loire, Seine and Scheldt). These potential endocrine disrupting chemicals were present in European coastal waters. Even if their concentrations were well below the Maximum Residue Limits set by the governments, they induced alterations of the endocrine system. We established correlations between contaminant concentrations and effects on the thyroid system in sea bass. The contaminants induced modifications of the metabolic pathways of thyroid hormones and enhanced thyroid hormone synthesis. The activity of T4 Outer Ring Deiodinase was increased, that leads to an intensified conversion of thyroxine (T4) to its more biologically active form triiodothyronine (T3). Meanwhile, the activity of T4 sulfatation was reduced, that leads to a lowered biliary excretion of thyroid hormones. The modified metabolic pathways of the thyroid hormones can be interpreted as a tool to homeostatically maintain the thyroid hormone status. Of all tested compounds, the higher chlorinated PCBs seemed to be the most implicated in this perturbation. The nature of thyroid hormone synthesis, signalling and regulation is highly conserved among vertebrates. Although we cannot extrapolate thyroid toxicity data directly from one species to another, these environmental factors may well affect thyroid function in other species, including humans. [less ▲]

Rangeland or natural arid pastures of Morocco are ecosystems where there is a natural or seminatural vegetation composed of steppes, shrubs and grassland. They cover about 82% of the Moroccan arid lands. These areas represent livelihoods for thousands of people and protect the country from desertification. Despite the importance of the rangelands and the threat of desertification, it is surprising that up to date there is no comprehensive assessment of their condition and their evolution, hindering any plan for desertification alleviation. However, the available information on selected pilot areas shows that these rangelands are threatened by desertification. It’s associated with biodiversity loss and contributes to climate change. The leading causes of land degradation are the human actions combined with climate. The establishment of a comprehensive surveillance system based on remote sensing, biophysics and socio-economic data must be envisaged to provide policymakers with an operational tool adapted to the spatio-temporal monitoring of desertification.

Si pour Werner Herzog le rôle du spectateur semble réduit à celui d’un récepteur passif, pour Alexander Kluge en revanche, le spectateur et sa mémoire des images doivent conduire à l’élaboration d’un sens supérieur que la subjectivité du seul auteur serait incapable de faire émerger. Mais, leurs pratiques documentaires respectives se fondent aussi sur la perception d’une figure complexe, celle du cinéaste, constitutive d’une relation que le film contribuera à instaurer entre le réalisateur et le spectateur. L'identification de cette figure permet de "réconcilier" Alexander Kluge et Werner Herzog, deux représentants du Nouveau Cinéma Allemand, que la plupart des histoires de ce cinéma opposaient jusqu'à présent.

Endotoxemia is the first mortality cause in equine intensive care. In humans with septic shock, some echocardiographic indicators are used to predict the efficiency of fluid resuscitation and outcome, allowing an early-goal-directed therapy. Echocardiography has never been investigated for this indication in horses. The aim of this study was to assess the prognosis value of echocardiographic and Doppler parameters of left ventricular (LV) function in horses with severe endotoxic shock. Twenty-one horses admitted to the clinic for colic with clinical signs of severe endotoxic shock underwent Doppler echocardiographic examination. LV echocardiographic and Doppler parameters were compared between the survivors (n=6) and the non-survivors (n=15) horses using a multivariable ANOVA analysis. The pre-ejection period to ejection time ratio (PEP/ET) of the Doppler aortic flow was significantly higher in the non-survivors than in the survivors group. All other measured parameters (including heart rate and end-diastolic-volume) were not significantly different between the groups. Doppler parameters of left ventricular function are subject to high variability and low repeatability in horses. This might explain that most variables were not significantly different between the two groups. Moreover, the number of investigated horses was limited, especially in the survivors group. However, with comparable HR and LV preload, a higher PEP/ET suggested a more compromised systolic dysfunction in the non-survivors. PEP/ET is often considered to be one of the best indicators of systolic function in horses and its measurement might therefore be useful in indicating the need for inotropic support in the management of horses with endotoxic shock.

Several rectal biopsy techniques have been reported in horses and sites vary between 15cm or 30cm from the anus, and on the rectal floor or roof. The aim of this study is to evaluate the safety of the technique performed with a uterine biopsy claw and the diagnostic value of rectal biopsies. Eight rectal biopsies, taken at 2H, 4H, 8H, 10H of the rectal wall respectively, each at both 15cm and 30cm from the anus, were taken pre-mortem with a uterine biopsy claw from 12 horses destined to euthanasia. Seven of these horses suffered from weight loss or chronic diarrhoea and 5 were control horses euthanized for non-digestive reasons. At the post-mortem samples of duodenum, ileum, caecum, colon and rectum were taken and the rectum was inspected for macroscopic lesions. Histopathology was performed on haematoxylin-eosin stained slides of all samples. Statistical analysis was performed with Fisher’s test. Sampling was considered easier at 2H for a right-handed person. Necropsies show that 91% of biopsies located 30cm from the anus and 48% of biopsies located 15cm were taken cranial of the retroperitoneal reflection. Hematomas (44%) existed especially on the ventral side. Inflammation at histology was significantly more important in rectal biopsies sampled at 30cm from the anus and in sick horses compared to 15cm and control horses respectively. The results of this study suggest that rectal biopsy could be an interesting ancillary test in horses with chronic diarrhoea or weight loss, but also shows the limits of the technique. [less ▲]

Traumatic wounds and particularly limb wounds in horses can be difficult to treat. Horses show protracted and weak inflammatory reaction in the first stages of the wound healing causing delays[1]. Several types of treatments have been tested in order to promote wound healing in horses, with variable success[2]. Vacuum-assisted closure(VAC) has been used in human medicine for over a decade now, but only one regarding a horse is available [3].

Cette conférence étudiera les voyages financés par l’État français aux XVIIe et XVIIIe siècles en vue d’une acquisition de nouvelles connaissances sur le monde en dehors de l’Europe. Cette période fut témoin d’un changement radical de l’exploration scientifique outre-mer. Pendant le règne du Roi Soleil, et sous l’impulsion de Colbert, les voyageurs académiques partant de la France ainsi que certains Français résidant dans les territoires d’outre-mer recevaient des instructions pour mieux orienter leurs observations et améliorer la collecte de données, et ceci afin de recueillir des connaissances qui seraient utiles à l’État. Les projets à petite échelle prévalaient. Grâce au soutien d’institutions royales comme l’Académie Royale des Sciences ou le Jardin du Roi, des individus comme Charles Plumier, Joseph Pitton de Tournefort et Louis Éconches Feuillée ramenaient des échantillons et descriptions de « plantes utiles ». D’autres comme Jean Richer faisaient des observations astronomiques dans l’hémisphère Sud, ainsi améliorant non seulement la connaissance géographique, mais aussi les techniques cartographiques et les compétences dans le domaine de la navigation. Sous Louis XV vint une amplification des entreprises. La rivalité avec l’Angleterre conduisait les Français vers le Pacifique. Science, exploration et géopolitique se confondaient. De vastes équipes de chercheurs montaient à bord de navires militaires. Les expéditions enrichirent les collections scientifiques de Versailles et des institutions royales à Paris. Sous Louis XVI ce processus culmina dans l’expédition de La Pérouse. Trois aspects de la politique scientifique française dans le domaine de l’exploration seront analysés ici en détail: les mécanismes de patronage et de protection, les mécanismes d’approbation scientifique, et la mise à profit des connaissances rassemblées par les voyageurs.

Dans le cadre d’une analyse du caractère transversal de la politique de mobilité, nous avons voulu étudier dans quelle mesure les questions environnementales (en l’occurrence la pollution de l’air par les particules fines) étaient intégrées dans les programmes d’action des autorités responsables dans les deux principales régions de Belgique. Notre choix est motivé par le fait que de nombreux projets d’action ont été proposés par diverses instances (administrations, scientifiques, partis politiques et ONG), par exemple pour limiter le soutien public aux moteurs diesel ou pour réformer le cadre de mobilité dans certains quartiers urbains. Mais jusqu’ici, un seul dispositif (Lascoumes & Le Galès, 2005) a franchi la ligne d’arrivée : le règlement « Smog90 » qui limite la vitesse de circulation sur autoroutes à 90 km/h en cas d’épisode de smog reporté par la Cellule Interrégionale de l’Environnement. La politique de mobilité reste fortement marquée par une logique de développement d’infrastructures et ne prend que marginalement en compte l’impact des différents plans sur la qualité de l’air : greening of mobility is still limited. Pourtant, les champions de la cause ne manquent pas, que ce soit du côté des scientifiques ou des administrations régionales et fédérales en charge des politiques de santé et d’environnement (Hood & Rothsein, 2001). Pour comprendre les freins limitant la construction d’une approche transversale sur les questions « environnement – santé – mobilité », nous avons analysé les dispositifs mis en place pour rédiger et gérer les plans d’action sur la qualité de l’air, définis au niveau des régions et au niveau fédéral pour répondre aux obligations européennes (Directive CAFE, Clean Air For Europe, 2008). L’analyse montre comment la définition des objectifs européens en termes d’immission plutôt que d’émission limite la gamme des actions envisageables pour des petits états comme la Belgique et entre en conflit avec les projets politiques des deux Régions de se positionner comme des « logistic hubs » sur le territoire européen (Buisson-Fenet, 2008). Dans le cadre du projet de recherche SCoPE, une enquête en ligne de type Delphi associant des acteurs de l’action publique en charge de la mobilité et de l’environnement (scientifiques ou administratifs) a été menée au sein des deux plus grandes régions. La recherche montre que chacune d’elles a développé des formes de gouvernance différentes, l’une en réseau de coopération souple et l’autre sous forme d’une agence centralisée. Néanmoins, les acteurs des deux régions soulignent les mêmes freins au développement d’approches politiques transversales : un contrôle strict de l’agenda organisé par les cabinets politiques qui sont en Belgique de larges structures peuplées d’experts nommés par les partis politiques. Alors que l’ambition et la nature du cadre européen demanderaient le développement d’une approche transversale et transpolitique, les répondants dénoncent l’absence de coopération entre d’un côté les scientifiques et experts technico-administratifs et de l’autre, les responsables politiques : les incitants à la création de mesures transversales ne peuvent se dessiner qu’à la suite de situations de crise ou sous la pression d’un tiers, par exemple le public, les ONG ou les médias. À travers ses aspects multi-niveaux, interdisciplinaire et transversal, la politique de qualité de l’air, telle que perçue par les répondants au Delphi, témoigne de la difficulté de dessiner des nouveaux instruments d’intervention et de la nécessité de prendre en considération les dimensions administratives, politiques et sociales pour organiser un changement de l’action publique (Simoulin, 2003).

Le projet Walphy a pour objectif d'améliorer la qualité écologique de deux masses d'eau, le Bocq et l'Eau Blanche, dans le but de répondre aux exigences de la Directive européenne sur l'Eau (2000/60/CE). Suite à une évaluation de la qualité physique du milieu, des travaux d'aménagement sont entrepris suivant 2 axes de réhabilitation : - la continuité longitudinale qui concerne la libre circulation des poissons et des sédiments, - la continuité transversale responsable des échanges du cours d'eau avec ses zones annexes. Ces chantiers - pilotes font l'objet d'un suivi scientifique afin d'analyser les impacts sur l'hydromorphologie (transport des sédiments, diversité des habitats …) et sur l'écologie (végétations, macroinvertébrés et populations piscicoles). Le projet a démarré en janvier 2009, il est co-financé par l'Union Européenne pendant 5 ans. La coordination est assurée par la Direction des Cours d'Eau non Navigables (DCENN - DGARNE) en collaboration avec les Universités de Liège (Laboratoire d'Hydrographie et de Géomorphologie Fluviatile LHGF) et de Namur (Unité de Recherche en Biologie des Organismes URBO).
