Dès le début des années 2000, l'Organisation Mondiale de la Santé invite les gouvernements à promouvoir la santé mentale de leurs citoyens, et en propose une conception spécifique ainsi que des solutions thérapeutiques et politiques, parmi lesquelles la participation des usagers. Progressivement, les recommandations de l'OMS intègrent le discours politique belge. Il faut pourtant attendre 2005 pour qu'elles trouvent une expression tangible, au sein d'un dispositif d'action publique. Celui-ci comprend deux niveaux. D'une part, des projets locaux au sein desquels professionnels et usagers expérimentent les conditions de travail en réseaux de soins. D'autre part, un volet transversal où les représentants des projets partagent les enseignements issus de pratiques novatrices, afin de les inscrire au sein de recommandations destinées aux décideurs politiques. Au travers d'une étude de cas portant sur le volet transversal, nous nous proposons de confronter cette conception de la santé mentale, ainsi que le discours sur la participation qui l'accompagne, aux pratiques qui se déploient dans leur sillon. Combinant analyse documentaire, entretiens semi-directifs et observations, cette étude de cas nous autorise effectivement à décortiquer les ressorts d'un processus de participation, et à interroger le recours aux savoirs d'expérience, son utilité, et son utilisation.

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 et, plus particulièrement, dans les limites des cadres prévus à leur participation ? Ce faisant, 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 volontés du citoyen ? Et ce dernier n’était pas légitime, peut-il être crédible ? Selon nos recherches empiriques basées sur une analyse comparative de cinq conflits d’implantation, nous pouvons à ce stade établir que, d’une part, l’impératif délibératif (Sintomer, Blondiaux, 2002) est traversé par une double logique d’action symbolique envers le citoyen (autrement dit, légitimer le processus par sa présence) et d’intérêts des acteurs, en particulier l’autorité publique. Confronter à cette double logique, nous proposons de mettre en exergue les différentes formes d’appropriation ou de réappropriation de la participation par le citoyen. D’autre part, nous démontrerons que la participation du citoyen, qu’elle soit formelle (prévu par le processus) ou informelle (débordement du processus), est assujettie aux intérêts de l’autorité à qui revient la décision publique. Ce faisant, il nous intéresse, dans cette contribution, en procédant d’une démarche inductive (Grounded theory, Glaser, Strauss, 2010) en maximisant d’abord les différences (cas par cas), puis en minimisant les différences entre nos cas d’étude, de comprendre (1) quelle place le processus décisionnel accorde au citoyen ordinaire, (2) quel est le poids de ces citoyens qui décident de s’insérer dans le processus et que nous nommons « experts d’usage » et (3) quelles sont les conditions de sa « crédibilité » dans le processus. Pour y répondre, nous recourons à deux recherches menées sur un an entre 2010 et 2011. La première a trait au projet de construction d’une mosquée dans le quartier de Glain à Liège (Belgique). Cette recherche portait initialement sur la place du citoyen dans les négociations associées à un tel projet d’implantation et sur les arguments qui s’y développent. La seconde recherche, commanditée par Electrabel (GDF Suez), est un projet ponctuel dont le comité d’accompagnement est composé d’acteurs industriels et de décideurs publics. Dans ce cadre, le centre de recherches Spiral (Université de Liège, Belgique) s’intéresse au processus décisionnel et à la participation citoyenne menant à la mise en place de quatre projets éoliens répartis sur le territoire de la Région wallonne. Nous identifierons, dans cette contribution, au préalable le cadre légal permettant la participation du citoyen dit « ordinaire » afin de le confronter, par la suite, à sa réappropriation du processus, au delà des cadres formels de la procédure. Nous proposerons à ce titre de développer trois indicateurs que nous attribuons à ce citoyen « expert d’usage », à savoir, leur capacité à connaître (« il sait »), leur capacité à agir (« il peut ») et leur capacité à argumenter (« il argumente »). Nous reviendrons enfin sur l’importance du contexte qui entoure ces cas d’étude et qui est, selon nous, un élément essentiel pour comprendre l’influence possible que pourrait avoir le citoyen dans le processus.

Geothermal energy systems efficiency relies on the quantification of the thermal properties of the ground. The estimation of those properties can be done by means of thermal response tests (TRT) or thanks to values found in literature tables; the first approach provides relatively limited information since the measures are done in boreholes and the values from general tables can present a lack of accuracy. Geophysical methods might be useful in order to yield additional information for thermal properties estimation on higher investigation scales. In this study, electrical resistivity tomography (ERT) is used to monitor the evolution of heated water injected into an unconfined aquifer. Both heat injection and storage were monitored during a total period of 17 days. The principal conclusion is that the use of ERT is efficient to monitor the progressive temperature increase and decrease in the aquifer due to the presence of the heated plume. The resistivity distributions calculated by inversion were compared with electromagnetic borehole measurements and were consistent in the case of the storage phase, whereas a higher gap remained between measured and calculated resistivities for the injection phase. A conversion of the calculated resistivities into temperature values enabled a validation with temperature logs for the storage phase, while the temperature deduced for the injection profiles were too low. Those differences are justified by the fact that different error models were used to proceed to the imaging of the heat injection and storage. This work demonstrates the ability of ERT to monitor geothermal experiment in shallow aquifer. Keywords: geothermal energy, electrical resistivity, electromagnetic method, heat transfer, inversion process, thermal response test. [less ▲]

While 3D cinema is becoming more established, little effort has focused on the general problem of producing a 3D sound scene spatially coherent with the visual content of a stereoscopic-3D (s-3D) movie. The perceptual relevance of such spatial audiovisual coherence is of significant interest. In order to carry out such experiments, it is necessary to have an appropriate s-3D movie and its corresponding 3D audio track. This paper presents the procedure followed to obtain this joint 3D video and audio content from an existing animated s-3D film, problems encountered, and some of the solutions employed. [less ▲]

Partant de la réflexion sur le système international proposée par le Professeur D. Battistella dans son récent ouvrage "Un monde unidimensionnel" (2011), la présente contribution propose de s’interroger sur le concept de "puissance" en Relations internationales (RI), en s’appuyant sur le cas chinois. La prééminence de la conception réaliste a longtemps cadenassé le champ d’étude de cette notion centrale en RI aujourd’hui fortement contestée (Barnett et Duvall, 2005). L’étude de l’émergence de "nouvelles puissances", telles que le Brésil, l’Inde ou encore la Chine, est à cet égard éclairante et riche d’enseignements. Leur développement économique et l’affirmation de leur poids sur la scène internationale s’accompagnant d’un discours de responsabilisation et de légitimation (multipolarisation du monde, coopération Sud-Sud, etc.), l’efficience de leur stratégie de projection internationale ne dépend pas seulement de leurs ressources – matérielles et immatérielles, ainsi que de leur aptitude à les mobiliser adéquatement . Elle tient également à la perception de leur "statut" par les autres acteurs du système international, dont au premier chef leurs pairs et les puissances occidentales. Sous cet angle, la représentation et la reconnaissance extérieure participent de la capacité d’influence des acteurs étatiques sur la scène mondiale (Santander, 2009). De cette approche échoit une nécessaire recomposition du concept de "puissance" en RI. À l’image de la puissance chinoise bardée d’un discours "anti-hégémonique" aux accents tiers-mondistes , celle-ci ne se peut se définir exclusivement en terme de capacités, mais également en termes d’image (autoperception et représentation) et de reconnaissance internationales. Partant de l’étude de la stratégie de projection internationale de la Chine, les différentes dimensions de sa puissance peuvent être appréhendées à travers ses actions de politique extérieure (multidirectionnelle) et la diplomatie incantatoire y afférent (discours officiels), et l’efficience de sa stratégie évaluée à travers l’écart entre le discours (promesses) et la réalité (réalisations concrètes). Engagée dans la construction d’un statut de puissance, la Chine émerge en tant que "nouvel acteur" régional et global, mêlant multilatéralisme et Realpolitik, coopération et nationalisme, consensus des partenaires et rapports de force : Pékin mise en réalité sur le multilatéralisme à des fins multipolaires. (Références: BARNETT M. et DUVALL R., « Power in International Politics », International Organization, n° 59, Winter 2005, pp. 39-75 ; SANTANDER S.

Un modèle, RTDrift, a été développé pour estimer la contamination causée par la dérive pour les pulvérisateurs à rampe en cours de traitement. Un pulvérisateur a été équipé de capteurs pour mesurer les paramètres de la dérive dont la pression de pulvérisation, les mouvements de rampe, la vitesse et direction du vent, la température et l’humidité ainsi que la géo-localisation. Pour chaque position successive des buses, un modèle de diffusionadvection gaussien avec sédimentation est utilisé pour calculer à partir de la buse le transport de chaque classe de gouttes déterminée préalablement par granulométrie laser en prenant en compte l’évaporation. Différents essais de terrain ont été réalisés où la dérive a été mesurée à différentes distances par fluorométrie sur collecteurs. La comparaison avec le modèle montre une estimation satisfaisante de la dérive sur base des mesures embarquées et offre le potentiel d’un estimateur de dérive en temps réel. Les pistes d’améliorations ultérieures sont évoquées. [less ▲]

In liberalized network industries, entrants can either compete for service using the existing infrastructure (access) or deploy their own infrastructure capacity (bypass). In this paper, we demonstrate that, under the threat of bypass, the access price set by an unregulated and vertically integrated incumbent is compatible with productive efficiency. This means that the entrant bypasses the existing infrastructure only if it can produces the network input more efficiently. The incumbent lowers the access price compared to the ex-post efficient level to strategically deter inefficient bypass by the entrant. Accordingly, from a productive efficiency point of view, there is no need to regulate access prices when the entrant has the option to bypass. Despite that, we show that restricting the possibilities of access might be profitable for consumers. [less ▲]

La dosimétrie ou accumulation vocale permet d’objectiver le comportement vocal en situation écologique. Différents types d’accumulateurs vocaux existent actuellement sur le marché. Il s’agit d’appareils portables qui mesurent la durée de phonation, l’intensité et la fréquence fondamentale moyenne de la voix. Ces données sont extraites plusieurs fois par seconde à l’aide d’un accéléromètre fixé sur le larynx, et relié à un microprocesseur stockant les données recueillies tout au long de la journée. Les données sont ensuite téléchargées sur un ordinateur et analysées à l’aide d’un logiciel prévu à cet effet. Cette étude tente de quantifier la charge vocale au sein d’une population d’enseignants, reconnue comme étant des professionnels de la voix. L’accumulateur utilisé est l’Ambulatory Phonation Monitor, Model 3200 (KayPENTAX, Lincoln Park, NJ). La récolte de données durant 1 semaine de travail chez 23 enseignants nous a permis d’objectiver l’utilisation vocale propre à cette population. [less ▲]

This paper deals with the 17th century information explosion and its influence on scholarly reading behaviour. The invention of the printing press had increased drastically the amount of books and at the same time, the volume of knowledge. As a result, it became very difficult for researchers to embrace the full account of available science. Starting from the work of the French libertine sceptic François de La Mothe le Vayer (1588 - 1672), the analysis will focus on two major questions of 17th century research: The first question “Is the immense profusion of books instructive or rather confusing?” will be the basis for a second one: “Hasn't everything been said? Is it still possible to add something to this colossal knowledge?” [less ▲]

The studied area covers over 45 km² of a steep and still rustic natural region. The bedrock is composed of metamorphised palaeozoic sedimentary and magmatic rocks, recovered by mesozoic sediments, mainly carbonates. The topics developed here are bibliographical research, field work, data-gathering (outcrops, use of geomorphology, substratum-related vegetation,...), and the design on ArcGIS software, among others.

Hitherto identities have been one the main driving forces of the federal dynamics in Belgium and they have played an active role in the transformation of the country from a unitary state to a federal state. More recently, while discussions – and tensions – have been continuously very hot about the reform of the federal state, the autonomist discourse has been – at least to some extent – denationalized and the emphasis on identities has been replaced by a more rational discourse, i.e. a discourse of good governance. That is to say, the partisans of more autonomy for the regions make their case not on the basis of identity differences between Flemings and Walloons but rather on differences about economic and political governance between Flemings and Walloons. On the other hand, while partisans of the status quo still hold a strong – albeit not exclusive – Belgian identity, they also put forward a discourse of good governance but based on a well-balanced federal system where both the federal government and the regions/communities have strong powers. Therefore, one might wonder whether these – new – discourses have a real impact on the citizens (and on their electoral behaviour) and above all what shape their attitudes towards federalism in Belgium; i.e. whether identities, good governance or a combination of both are the main explaining variables of preferences for the future of Belgium. Using the PARTIREP 2009 Election survey, we seek to disentangle this complex puzzle and shed light on citizens’ preferences for the future of their country. In a time when the Belgian federation is stuck in a deep crisis, such endeavour should bring interesting insights on the federal dynamics from a citizen’s perspective. [less ▲]

In October-November 2010, more than 5000 Belgian students from both side of the linguistic border have been asked to “draw Belgium” – no other guidelines were given. In addition to this rather unusual question, the students were surveyed on their political interest, political knowledge, identities, political perceptions and preferences as well as their attitudes towards Belgium and her future. In a time when Belgium is stuck in a quite deep institutional crisis, this innovative research yields original data on the political visions held by a generation that always lived under federalism and that might soon decide upon the future of the country. The results for this sample can also be compared to samples drawn from the whole population and therefore offer much insight about how young Belgians differ – or not – from previous generations. Moreover, such a design allows for comparisons within and between the two main linguistic communities; this is likely to offer a much more diverse portrait than the too-common picture of two monolithic blocks at war with each other along linguistic lines. Above all, with this research we can indirectly explore the processes – of socialization – behind the formation of political preferences and more specifically how socio-demographics, political knowledge, political interest, voting behaviour interact with the students’ representations and attitudes vis-à-vis their country and its future.

This talk focuses on the identification of respondents with cheating behaviour to educational or psychometric tests. Cheating behaviour is often observed when some examinee with low ability level, tries to get correct responses (in some way or another) to get higher grades. This results usually in a response pattern that does not fit the underlying item response theory (IRT) model and severely affects the estimation of ability level. Until now, several indices of misfit have been proposed, and they seem accurate for detecting cheating (as well as other misfitting behaviours). Unfortunately, none of these indexes permit: (a) to determine which type of behaviour is encountered, and (b) to propose a corrected estimation of the examinee’s ability level. The purpose of this talk is to present Raîche’s multidimensional model as an extension of the usual IRT models but incorporating additional person parameters to characterize misfitting behaviour. Emphasis is put on a simple model with personal pseudo-guessing variation to detect trends in cheating. Results from a simulation study indicate that, in the absence of cheating, the multidimensional model returns similar estimates than the traditional IRT models, while in the presence of cheating, the person pseudo-guessing parameter is an accurate index of misfit and the person ability estimates are less biased than its traditional counterpart.

Influenza A viruses cause annual epidemics and occasional pandemics that spread worldwide. The nucleoprotein is essential for the survival of this virus and is thus well-conserved. We developed a quantitative electronic biosensor displaying a protein recognition thanks to the covalent grafting of anti-nucleoprotein antibodies. The detection device lies on interdigitated array microelectrodes (IDAM), covered with alumina (Al2O3) to protect the underlying aluminum and enhance the electrical coupling. As the dimensions of the IDAM can determine the sensitivity of the sensor, we processed 4 structures with varying electrode widths and spacings in the same silicon chip and assessed their individual performance. The sensing area of each sensor is 200*200 µm2 and the overall chip-size is 3*3 mm2. The sensor is mounted in a DIL-16-package partially encapsulated by resin. [less ▲]

This talk focuses on the issue of differential item functioning in psychometrics. An item is said to function differently if examinees from different groups, but with the same ability levels, have nevertheless different probabilities of endorsing this item. Many methods were proposed to detect DIF, either based on statistical methods (such as logistic regression) or on IRT models. The talk is divided into three parts. In the first part, a brief overview of the DIF framework and methods is proposed. In the second part, a recent, conceptually different approach to DIF will be introduced. It consists basically in flagging as DIF, the items that are outlying withb respect to other items. This approach is based on robust statistical tools for outlier identification. It cancels the issue of Type I error inflation and the need for purification of the anchor set. In the third part, it is briefly outlined how this approach easily extends to the simultaneous comparison of more than two groups of examinees; multivariate robust estimators of location and scale are required, but their use might overcome the standard methods for simultaneous pairwise comparisons.

Main component of animal venoms is peptide toxins, which are highly structured by several disulfide bridges. Disulfide bridges fill different roles as increasing the toxins efficiency by lowering their immunogenicity or providing the adequate conformation to efficiently bind to the biological receptor. The sequencing and the determination of the cysteine pairing is still challenging and therefore an important step in structural analysis. In this work, we present a new strategy to sequence structured toxins and assign S-S bridges using ion mobility resolved MS/MS. The method relies on the analysis of partially reduced multiple-disulfide peptide. The mixture of the different forms is resolved by ion mobility, followed by MS/MS acquisition on each mobility separated species. The proof of concept has been successfully conducted on α-CnI, a toxin purified from the venom of Conus consors marine snail. The toxin’s sequence contains four cysteines linked together with two disulfide bridges. α-CnI was partially reduced by a small excess of tris(carboxyethyl)phosphine (10:1). The resulting mixture was purified before analysis by infusion nanoESI-Synapt-G2. Fragmentation was performed after the mobility cell, to obtain specific fragments of each species. Partial reduction of α-CnI results in a mixture of oxidized (the two disulfides are formed), reduced (the two disulfides have been reduced) and partially reduced forms (one of the two disulfides has been reduced). The arrival time distribution of triply charged ions reveals the presence of 4 different species, characterized by different relative cross sections in the gas-phase. Mass matching allows identifying the species: the first mobility (the most compact structure) was identified to be the oxidized folded toxin (M). The latest peak, corresponding to the larger cross-section, was identified as the fully reduced toxin (M+4Da). The second and the third mobility peaks were attributed to the two partially reduced forms in which only one disulfide bridge was reduced (M+2Da). The change in ion mobility depends on which S-S bridge is reduced. Ion mobility separated species give characteristic fragment ions upon fragmentation in the transfer cell (i.e. after ion mobility separator). Interestingly, fragment ions coming from partially reduced species, especially the C-S or S-S bond cleavages, clearly indicates that the disulfide linkage of α-CnI is (Cys1-Cys3) and (Cys2-Cys4) as expected from literature. The method is now being applied with success to more complex systems containing 3 or 4 disulfide bridges. The influence of the charge state on the mobility separation is systematically analyzed in terms of structural implications. [less ▲]

Differences between clinic and out-of-clinic BP, defined as white coat effect (WCE), white coat hypertension (WCH) or masked hypertension (MH), can leat to misdiagnosis and -handling when decisions are solely based on clinic BP measurement. One aim of the study was to examine the risk factors of WCE and MH in late KT. Conclusion:Out-of-clinic BP monitoring should be encouraged to be applied more often in high risk-populations such as KT, especially when risk factors for WCE or MH are present. [less ▲]

The test setup and characterization parameters of ultrathin EUV filters under high solar flux are presented. These 150nm thick aluminium filters are used at the entrance of the Extreme Ultraviolet Imager (EUI) payload, which is developed at the Centre Spatial de Liège for the Solar Orbiter ESA M-class mission. The solar flux that they shall have to withstand will be as high as 13 solar constants when the spacecraft reach its 0.28AU perihelion. A specific design based on additional ribs has therefore been developed to enhance the thermal behaviour and heat evacuation while preserving its optical properties. It is essential to assess the design performances under the Solar Orbiter high solar flux. Therefore, thermal vacuum test under 13 solar constants will be performed. The filters temperature profiles will be measured during the tests through infrared imaging. A thermal correlation of the test will then be performed to deduce the filters actual thermal properties to be used in the global instrument geometrical and thermal mathematical models. [less ▲]

On board a satellite, the experiments and subsystems have to be maintained within specified temperature limits. Phase Change Materials (PCM) offer the possibility to store thermal energy directly as latent heat of fusion. Usually, the melting PCM can easily be used in reversible, closed systems. Two advantages of a PCM device are the stability of temperature control and the absence of moving parts. The heat-storage requirement is mainly defined by the duty cycle along the orbital period. A trade-off is presented for typical missions, which takes into account the temperature range, the weight and thermal conductivity of the PCM device together with the specific design of the container. Candidates PCM for space applications are reviewed according to their main characteristics such as latent heat, phase transition temperature, conductivity, density but also corrosion potential, hysteresis and ageing. Potential weight and power gains are finally presented for selected missions. [less ▲]

The VOTES project (Valuation Of Terrestrial Ecosystem Services in a multifunctional peri-urban space) aims to develop a framework to evaluate ecosystem services from a social, economic and environmental point of view, where local stakeholders and end-users have a central role in the valuation process, as they are the direct beneficiaries of the provision of services. Within this project, the framework is applied to a case study in central Belgium, known for its strong peri-urban character, due to the proximity to Brussels. To the end, this quantitative tool designed for a sustainable landscape management is also designed for the evaluation and the monitoring of ecosystem services for policy makers. The originality is that this framework will provide an integrated valuation of ecosystem services in a spatially and temporally explicit way, based on different steps in which we find biophysical valuation and landscape modelling: the valuation of the biophysical environment is an essential component of the VOTES framework. To carry through this biophysical valuation, we use the CARAIB model (CARbon Assimilation In the Biosphere), a dynamic vegetation model (DVM) adapted for the valuation of the ecosystem services. This model is combined with another spatial model, an agent-based model (ABM), used to project land use change into the future. Initially, CARAIB was designed to describe (non-managed) natural ecosystems dynamics over large spatial domains and at coarse resolution. In consequence, the model had to be adapted to the VOTES smaller scale case study (including a higher resolution) but, mainly, the model had to be modified to quantify key ecosystem services, e.g., through the addition of a module dedicated to (manage) crops. This new version of the model thus provides direct outputs on the biophysical values of ecosystem services, e.g., productivity (food/fodder, wood production, etc) or carbon storage, which leads to a mapping of these ecosystem services not only for the present, but also for the future until 2050. Indeed, the coupled DVM-ABM is used to construct future (dynamic) scenarios that include the major driving forces of the system (e.g., global socio-economic context, climate change, urbanization pressure, etc) together with adapted management. The computed scenarios will provide the changes in the biophysical system consistent with the socio-economic evolution, including changes in ecosystem structure and function. This will allow an estimate of a change in the provision of ecosystem service through time, so that the sustainability of ecosystem services under the studied scenarios can be assessed. [less ▲]

Este trabalho considera um caso particular de relação entre as imagens e os textos nas ciências ditas “exatas”. A relação que pretendemos abordar é o vínculo que existe entre as chamadas imagens simples ou imagens compostas e suas legendas, num corpus restrito de artigos da área de pesquisas em astrofísica. A principal questão deste estudo consiste em analisar as modalidades de articulação entre dois tipos de expressão que fazem parte de semióticas diferentes, ainda que relacionadas entre si. Neste caso, questionaremos a relação entre texto e imagem em um contexto peculiar, já que o propósito é de analisar a determinação acabada de uma imagem, ou seja, sua legenda. Além disso, esta apresentação pretende considerar dois tipos de articulações, analisando duas inscrições discursivas que pertencem a dois gêneros distintos: o artigo científico e o artigo de vulgarização. Assim, demonstramos um duplo interesse. Por um lado, desejamos entender as articulações específicas entre texto e imagem em um determinado gênero. Por outro lado, este breve estudo propõe insistir sobre a necessidade de um estudo mais geral e mais sistemático das relações variáveis entre as imagens e os discursos de que uma ciência se utiliza para se constituir.

Detailed asteroseismic analyses of 15 pulsating B subdwarfs have been published since a decade, including estimates of the masses of these stars. We present in this talk the empirical mass distribution for hot B subdwarfs on the basis of this sample. We find a sharp mass distribution with a mean mass of 0.470 Msun, a median value of 0.471 Msun, and 68.3% of the stars fall in the narrow range of mass 0.441-0.499 Msun. In a second experiment, we augment our sample with the addition of 5 hot B subdwarfs components of eclipsing binaries, with masses reliably determined by light curve modeling and spectroscopy. The new mass distribution is very similar to the former one with a mean mass of 0.469 Msun, a median value of 0.471 Msun, and a range 0.436-0.501 Msun containing 68.3% of the stars. We also discuss in this talk how these empirical mass distributions, although still based on small-number statistics, compare with the expectations of stellar evolution theory. [less ▲]

Long-term changes of surface plankton dynamics are studied from three decades at a permanent station in the oligotrophic Bay of Calvi (Corsica, northwestern Mediterranean) where water quality is unbiased by terrestrial inputs. As a distinctive feature of the Bay, a plurimodal plankton bloom occurs generally between January and April, with very large interannual variability reaching one order of magnitude from one year to another. Later in the season, the plankton biomass remains very low from May to December. Contrarily to the 1979 - 1998 period where a continuous decrease of phyto- and zooplankton biomasses was observed, observations from the last decade (1999 - 2011) emphasize abrupt changes in plankton biomass and bloom duration from one year to another in response to succession of mild and rigorous winters. Studies conducted to understand mechanisms controlling plankton variability emphasize a close relationship between winter wind stress intensity, water temperature, nutrient inputs and phytoplankton biomass. Total phytoplankton biomass is maximum during years characterized by high winter wind stress and low winter water temperature. From a specific point of view, flagellates are always the dominant component of the winter - spring phytoplankton communities. However, diatoms tend to be more abundant during rigorous winter years. Shifts in phytoplankton community structure contribute to control the dynamics of zooplankton that rely on phytoplankton as food and influence the temporal succession of zooplankton assemblages. Time-series results indicate the high sensitivity of the plankton ecosystem to climate change and confirm that the Bay of Calvi reacts rapidly to external perturbations, which are driven by climate variation.

Since 1993, Belgium is officially a federal state, composed of – three – communities and – three – regions, as the – new at the time – first article of the Constitution proclaims. The history of federalism in Belgium is therefore quite recent. Nevertheless, the story is – much – longer since it starts with the independence of Belgium from the United Kingdom of the Netherlands in 1830 . The very beginning of a state and the underlying causes of its creation, as well as its place on the map, the timing of its creation and the characteristics of the elites who take the lead and define the new state’s nature are of crucial importance and these elements shape the country’s political development for centuries . Nonetheless, although the beginning of any state sets up a path dependency , there are also critical junctures along its political development which in turn influences the course of history. This is especially true for Belgium . Here, history and politics are intrinsically interrelated. Indeed, the current challenges on the Belgian federalism find their roots in the country’s history. Three main challenges face Belgian federalism: an ethno-territorial challenge, a socio-economic challenge and a political challenge, that is to say the future of the country itself. In this endeavour to assess the current challenges on the Belgian federalism, three variables have to be taken into account. The first variable is the territorial principle vs. personal principle debate, which constitutes the backbone of the so-called Belgian community question; it is also intrinsically related to the first challenge: the ethno-territorial challenge. The second variable is the political parties because they have played and play the major role in Belgian politics and therefore in the Belgian federal dynamics. The third variable is made of the people; that is, at the individual level, the inhabitants or the citizens or the voters and, at the collective level, the language groups of Belgium. These three variables are at the heart of Belgium’s past, present and future and continuously interact with one another. In order to offer a clear picture of these interactions, Belgium’s history is conceptually divided into three periods: before federalism (1830-1960), federalism (1960-2007) and after federalism (2007-onwards). These three periods shed light on the background of the current challenges on the Belgian federalism. On this basis, the recent institutional agreement which gives Belgium her sixth reform of the state is analyzed as it provides – tentative – answers to the first two challenges. This all leads to the last challenge – the end of Belgium? – dealt with in the conclusion. [less ▲]

In this presentation we use bi-directional energetic electron distributions from the MIMI-LEMMS instrument onboard Cassini, auroral observations from the Hubble Space Telescope (HST) and data from the UVIS instrument onboard Cassini to characterize the open-closed field line boundary in Saturn’s magnetosphere. The high-latitude open-closed field line boundary at Saturn is thought to be related to the main auroral ring of emission of the planet varying in location, intensity and latitudinal extent as well as in its homogeneity. This study extends the work on the plasmapause/open-closed field line boundary published by [1] by covering a larger data set at different local times and comparing the electron distributions with auroral observations. Based on energetic electron data we characterize the open-closed field line boundary in terms of temporal, local time variations and other parameters and we correlate the Cassini in-situ measurements to the observations of the main auroral ring at Saturn.
