Mon intervention entend constituer une contribution à l’histoire institutionnelle de l’enseignement du cinéma en Belgique francophone. Jusqu’ici l’histoire de l’enseignement du cinéma en Belgique s’est surtout élaborée par le biais de l’évocation des personnalités marquantes qui en ont été les acteurs (c’est par exemple dans le cadre d’un texte consacré à André Delvaux que Paul Davay évoque les débuts de l’enseignement du cinéma en Belgique dans son ouvrage, Cinéma de Belgique). L’histoire institutionnelle de l’enseignement du cinéma reste, quant à elle, largement à écrire. La mise en place de l’enseignement du cinéma en Belgique est due à diverses instances: la Cinémathèque Royale de Belgique, le Ministère de la Communauté française, les écoles d’enseignement supérieur non-universitaire et les universités. On examinera le rôle respectif de chacune de ces instances en évoquant leurs divergences de vue mais aussi leurs diverses collaborations. Faisant retour à des textes fondateurs, tel le rapport rédigé en 1966 par Victor Bachy pour l’Unesco, on montrera comment les clivages entre enseignement laïc et confessionnel qui divisent le paysage scolaire francophone en Belgique se sont répercutés au niveau de l’enseignement du cinéma, contribuant à son éparpillement. On envisagera les conceptions respectives de la culture cinématographique et des finalités de l’enseignement du cinéma qui se sont développées dans chacun des réseaux d’enseignement. On verra aussi comment les diverses écoles et universités ont défini leur spécificité en matière de contenu d’enseignement et d’approche du cinéma (théorique, pratique, pratico/théorique) pour se positionner les unes par rapport aux autres dans le champ de l’enseignement du cinéma en Belgique.

The far-infrared surveys of nearby main sequence stars performed since the launch of IRAS have shown that a significant fraction of main sequence stars are surrounded by cold dust populations. These surveys are now culminating with the the DUNES and DEBRIS key projects of the Herschel Space Observatory, which is more sensitive than ever and is able to detect cold dust populations with densities similar to that of the solar system Kuiper belt. However, little is known about the occurence of warm dust populations, the equivalent of our zodiacal cloud. Since 2005, high-precision infrared interferometers have opened a new way to directly resolve these exozodiacal dust populations. Interferometric observations enable to reach dynamic ranges (larger than 100:1) that are generally not achievable with classical spectro-photometric observations. We are currently carrying out a survey to characterise the hot dust populations around main sequence stars. The first results of this survey, performed on the CHARA array with the FLUOR instrument, will be presented in this talk. The results are based on a magnitude-limited sample of stars surrounded by cold dust and on an equivalent sample of stars showing no cold dust emission. The statistics for the occurence of bright exozodiacal disks will be presented, and compared with the Spitzer and Herschel results. The possible (dynamical) connections between the two populations will be discussed. We will also review the results obtained by other interferometers and discuss the on-going projects. [less ▲]

In this talk I discuss a significant objection that has been raised against the view of historical sciences held by Heinrich Rickert: the accusation of “fruitless formalism”. This accusation has been expressed by a large number of thinkers, including for instance Wilhelm Wundt, Edmund Husserl, Max Frischeisen-Köhler and Eduard Spranger. As one knows, Rickert answered the objection in the last editions of his major book, "The Limits of the Concept Formation in Natural Sciences". His strategy was, first, to distance himself from a certain interpretation I will call the “formal view”, and, second, to argue for the fruitfulness of his own, more sophisticated view. However, as suggested by other representatives of the Bade School (like Richard Kroner), it is doubtful that the Rickert view perfectly succeeded in resorbing the shortcomings of the formal view. - In the first, introductive section I will put the formalism-problem in connection with a definite sub-set of issues within the broader framework of the philosophy of history (1). In the second and third sections I will address two questions related, respectively, to the nature of historical form (2) and to the nature of historical material (3). I will then contrast the formal view with the Rickert view on the one hand and with Kroner’s contentual view on the other hand. In the last, conclusive section I will try to draw some general implications of the formalism-controversy (4). [less ▲]

The postal sector has dramatically changed in the recent years with the ongoing liberalization process and the increased competitive pressures from alternative communication channels (e-substitution). These two effects concur to decrease the mail volume handled by the historical operator which in turn may threaten the financial viability of the universal service and may call for a reform of the universal service. This paper examines the question of reforming the postal universal service, first by considering that the universal service remains confined in the postal word and, latter, by defining a universal service that includes postal and electronic technologies.

Introduction: Many situations justify a close collaboration between GP, OP and SIP. Health problems impact work activity and vice versa. An altered health situation confronts workers with the risk of exclusion from the labour market. An interprofessional collaboration is thus needed to promote a more active policy of rehabilitation of workers on long term sickness absence. The Belgian Ministry of Employment initiated this study to identify communication channels and tools that could support collaboration among those health professionals. Methods: To this purpose, 8 nominal groups were organised to think about proposals to improve interdisciplinary collaboration. In sum 42 GP’s, 16 OP’s and 16 SIP’s participated in the discussions. For the elaboration of the final proposals, the research team relied on a multidisciplinary expert group. Results: An asymmetric relation was observed; each group expressed the need to receive information from the two others, but proposals to transfer information were rare. Exchanges in the groups showed that reciprocal ignorance is important and communication modalities are poor. A profound revision of the information transmission procedures seemed necessary. Several practical proposals were made to improve communication in case of sickness absence over three months, to allow information transfer and to promote mutual respect between the three disciplines. Other proposals considered professional training, and professional competencies which need to be better defined. Discussion: Misconceptions of the role of the different professional disciplines form a barrier to an effective collaboration. Technical and regulatory measures alone will not bring about a real promotion of interdisciplinary collaboration. The proposals arising from the study will contribute to increase reciprocal knowledge between professionals from the three disciplines and thus form the basis of a more effective collaboration. In turn, the experience of collaboration could have a beneficial effect on the reciprocal representations of each partner role. [less ▲]

We have proposed and explored a novel sequence in MEMS fabrication process flow. The novel MEMS fabrication process flow can be shortly described as a “packaging first, MEMS release second”. We propose to package the MEMS device first (die mount, wire bonding and encapsulation) and to perform the MEMS release as the last step in the fabrication process flow. The standard route for IC manufacturing is, that the die packaging is the last step [1]. Such approach can’t be directly transferred and used for MEMS fabrication [2]. The main reason for that, that the MEMS device after the release becomes vulnerable to any physical and chemical exposure. Such exposure can occur during transportation, handling or any post-processing (incl. the packaging). [less ▲]

Our detailed understanding of the working engine of quasars is still incomplete. Several basic questions remain such as: How is the supermassive black hole in the center of quasars fed ? What is the geometry and kinematics of the gas flow near the black hole ? The slow advances in answering these questions during the last decades advocates for new research methods. The analysis of the microlensing-induced deformations of multiply-imaged quasars is one such technique. It starts to be used as a tool to measure the temperature profile of the accretion disk, to estimate the size and study the geometry of the region emitting the broad emission lines. However, up to now, these applications have concerned mostly a handful of systems. In this talk, I will discuss the occurence of microlensing in a sample known strongly-lensed quasars and present the variety of emission-line deformations which is observed. I will also explain how spectroscopic follow-up of strongly-lensed quasars in the survey era should provide important insights on the quasar structure. [less ▲]

Ces dernières décennies, des pressions de tout ordre ont induit une forte expansion de l’urbanisation en Europe, à laquelle la Belgique n’échappe pas. L’imperméabilisation des sols a par ailleurs été identifiée comme une des principales menaces pesant sur eux. Au-delà du constat de l’évolution des surfaces artificialisées en Wallonie, l’objectif de cette étude est d’identifier les sols les plus soumis à ce phénomène. L’élaboration de la Carte Numérique des Sols de Wallonie (CNSW) – à partir d’un document historique, la Carte des Sols de la Belgique levée à grande échelle entre 1947 et 1991 – et de la Carte Numérique d’Occupation des Sols de Wallonie ouvre des perspectives intéressantes à ce sujet. Plus spécifiquement, l’utilisation de cartes d’aptitude des sols pour l’agriculture, dérivées de la CNSW, met en évidence l’impact de l’artificialisation sur la réserve en sols de meilleure potentialité agricole (figure 1). Cette dernière a diminué de 5 % à l’échelle de la Wallonie suite à l’artificialisation des sols ces 60 dernières années. La réalité est plus contrastée à l’échelle locale. La moitié des 262 communes wallonnes se situe en deçà, tandis que d’autres ont perdu (du point de vue agricole) jusqu’à 50 % de leurs meilleurs sols, par ailleurs initialement fortement présents sur leur territoire. Autre constat : si la moitié des communes subit une artificialisation uniforme de ses sols, 20 % d’entre elles voient leurs meilleurs sols préférentiellement artificialisés par rapport à ceux de potentialité agricole moindre.Une analyse spatiale fine à plus grande échelle (figure 2) ouvre la voie à la compréhension des phénomènes en jeu et in fine à l’élaboration de recommandations face à la concurrence inévitable entre deux fonctions essentielles des sols : la production agricole et le support des activités humaines.

L’insuffisance rénale avec l’âge n’est pas une fatalité. Il faut prévenir très tôt les facteurs de risque cardio-vasculaire et les corriger au mieux pour éviter que ces facteurs n’agissent plus tard dans la vie et soient des facteurs de comorbidité très importants favorisant la dégradation fonctionnelle rénale et l’évolution vers une insuffisance rénale très sévère exposant le patient à un risque cardio-vasculaire, à des techniques de suppléance de la fonction rénale et à un décès plus rapide avec perte préalable de la qualité de vie. Il faut donc identifier précocement la réduction de la GFR et l’apparition d’une protéinurie, agir de concert ensemble sur de nombreux facteurs pour ralentir la progression. Ces facteurs sont souvent des facteurs de risque cardio-vasculaire, donc on fait un double coup en les corriger. La référence précoce lorsque vous remarquez une évolutivité de la GFR vers la baisse pour décider ensemble si un traitement de suppléance doit être lancé. Celui-ci ne sera décidé qu’en concertation commune si nous avons le temps de l’établir après avoir évaluer des niveaux d’autonomie de nutrition, de risque cardio-vasculaire, et tout cela intégré dans le côté social et environnemental du patient. Il faut rappeler ici l’importance des trajets de soins à proposer à tout patient insuffisant rénal en dessous de 45 ml/min, moment stratégique pour que le néphrologue puisse en partenariat avec le médecin généraliste contrer les perturbations de l’insuffisance rénale terminale.

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 notion de friction implique forcément celle de contact, ce qui, à l’évidence, intéresse au tout premier chef les images à caractère photochimique. Dans le cadre de cette communication, j'interroge la notion de friction dans le champ du cinéma d’expérimentation, en me concentrant plus particulièrement sur les films du cinéaste (et peintre) américain Paul Sharits (1943-1993). À partir de "Color Sound Frames" (1974), l’œuvre de Sharits connaît une mutation profonde. Pour une large part, le travail du cinéaste consistera désormais à refilmer des fragments de pellicule déjà impressionnés, images appartenant de facto à la catégorie du déjà-vu. Pour ce faire, Sharits mobilise un écran transparent et un projecteur trafiqué, dont il a ôté et la griffe, et le mécanisme d’obturation. Retournant l’une contre l’autre les deux machines sur lesquelles se fonde le spectacle cinématographique, procédant par « anti-cadrage » et reprise de vue, le cinéaste orchestre, au plus intime de ses œuvres, d’intenses rapports de friction entre le film second (ou film filmé) et le film premier (ou film d’accueil, celui qui se déroule sous nos yeux) ; il accuse, de manière très méthodique, les discordances qui affectent les deux niveaux de la représentation, que ce soit en termes de vitesse, de texture ou de stabilité des motifs. Ma communication se donne pour but d’étudier, dans tous ses enjeux, les frictions internes qui traversent les films tardifs de Paul Sharits, dont "Tails" (1976) et "Bad Burns" (1982). Dans le cas de ce dernier film, le rapport de friction s’exacerbe, se déporte et tourne au conflit ouvert entre l’image et la source lumineuse censée lui donner vie : il se solde ponctuellement par des destructions apparentes du support filmique, petits désastres figuratifs qui ont paradoxalement valeur, selon Sharits, d’actes analytiques à part entière.

The basic principle adopted in our studies is to use substrate limitation responsive biosensors in order to detect spatial glucose heterogeneities inside industrial bioreactors (whole-cell biosensor). Indeed, such heterogeneities cause a lowering of the biomass yield and an increase of by-products concentration. In this work, we have used these biosensors for the elaboration of a mini-bioreactor platform that can be used as a scale-down tool. Three green fluorescent protein (GFP) transcriptional reporters have been chosen in Escherichia coli, i.e. uspA::gfp, csiE::gfp and yciG::gfp. Our previous studies have shown that these kinds of promoters are induced in response of substrate limitation and exhibit a strong fluorescence attenuation when cultivated in heterogeneous bioreactors. This sensitivity to substrate limitation has been confirmed in the case of the csiE and yciG biosensors. A mini scale-down platform has been proposed as a high throughput tool to investigate rapidly the usefulness of a given microbial biosensor. This platform is composed of shake flask able to operate in fed-batch mode either by using the slow release or the intermittent feeding principle. The first system is based on a commercial package (Enbase) based on the enzymatic release of glucose in the medium. The Enbase system allows the generation of a very smooth glucose profile without any perturbations. For comparison purpose, we have also used an intermittent feeding that induces strong fluctuation at the level of the glucose and the dissolved oxygen concentration. Local heterogeneities have thus been reproduced at the level of these mini-bioreactors and these one have caused a decrease of GFP expression, as in conventional scale-down reactor. The presence of GFP in supernatants has also been noticed and seems to be correlated with the substrate limitation signal for the three cultivation systems considered in this work (i.e., chemostat, conventional and mini-bioreactors) and with the membrane permeability.

Computerized adaptive testing (CAT) is an efficient method to administer psychometric or educational tests and questionnaires. Unlike the standard fixed (“paper-and-pencil”) tests, items in a CAT are iteratively and optimally selected within a bank of available items, on the basis of previously administered items and the current ability estimate of the examinee. This general approach has several assets with respect to fixed tests: it reduces the risk of fraud, it allows for individualized questionnaires according to the examinee’s ability level, and fewer items must be administered to reach the same level of precision in the ability estimates. The purpose of this talk is threefold. First, a general overview of CAT is proposed and its main principles are quickly outlined. Second, a recently developed R package, called catR, is briefly presented and its functionalities are described. Finally, two applications are discussed. The first application is a live demonstration of catR, by using its by-default item bank about English aptitude assessment, and several CAT options. The second application focuses on the on-line testing platform Concerto, a web interface for the development and testing of CAT sessions that uses catR as underlying computational package. The R package catR was jointly developed with Gilles Raîche (Université du Québec à Montréal, Canada). The platform Concerto is under development by The Psychometrics Centre (Cambridge University, UK) under the supervision of Michal Kosinski and John Rust. [less ▲]

The bulk morphology of Jupiter's and Saturn's UV aurorae is conveniently divided into three components: 1) the main emission (main oval), 2) the satellites auroral footprints (equatorward of the main emission): Io, Europa and Ganymede for Jupiter and Enceladus for Saturn, 3) the polar emissions (poleward of the main emission).This schematic view is already providing useful information on the giant planets aurorae. However, a quick inspection of HST and Cassini UV images directly shows that this simplified classification does not really match the complex morphology of the auroral emissions. As an example, in the case of Jupiter's UV aurorae, it appears that the main emission is not forming an oval, not even a closed shape; it is far from uniform and its position and size vary with time and depend on the viewing geometry. A secondary emission appears equatorward of the main emission and many small scale features regularly appear, some of them periodically. Satellites auroral footprints themselves appear to be much more intricate than predicted by present models. These footprints are actually multiple, their location and number vary periodically with time and with the satellites orbital longitude. The polar emissions are also much more complicated than predicted. Each of the above effects is related to a specific physical phenomenon in the atmosphere, the magnetosphere, or even in the planet's interior. For instance, the spatial distribution of the satellites auroral footprints made it possible to demonstrate the existence of a magnetic field anomaly near the surface of Jupiter's northern hemisphere. Observations which might appear insignificant, like the multiplicity of the satellites footprints or their periodicity are actually extremely valuable because they reveal the complexity of the interaction, in this case between a moon and the magnetospheric plasma of the planet around which it is orbiting. The same applies to small scale auroral structures which depict crucial magnetospheric processes like hot plasma injection, flux-tube interchange or magnetic reconnection mechanisms. The growing HST and Cassini databases are shedding new light on the origin of Jupiter's and Saturn's aurorae. Mechanisms that we thought could be taken for granted may even be challenged. [less ▲]

It is well known that high latitude zones are very sensitive to climate change. As a result of global warming, ice sheet melting has increased which in turn has an influence on climate through modifications of the thermohaline circulation, feedback of ice albedo, sea level rise,. . . Svalbard is an archipelago located between 74 and 81◦ lat N and 60 percent of its area (62 248 km2 ) is covered with glaciers and ice sheets. The impact of global warming on the Svalbard cryosphere can be estimated with climate models. However, we need to use regional climate models as they offer the possibility of a higher resolution than general circulation models. We have carried out a simulation of the Svalbard climate over the last 50 years (from 1958 to 2010) with the regional climate MAR model (tuned for the Greenland ice sheet) at a 10 km resolution forced with the ECMWF reanalysis. As validation, the modeled climate has been compared to near surface measurements at several weather stations through the archipelago. The results show a large interannual variability of the surface mass balance over Svalbard along with an increasing melting. The increase in temperature is responsible for the melting rate and the interannual variability is due to the variations of the mean summer temperature. [less ▲]

The postglacial re-colonization of Europe by temperate tree species from a few glacial refugia during the Holocene (10,000 BP) is a very interesting case to study the mechanisms of the vegetation dynamics. The relative roles that played the climate conditions, the species dispersal capacities and the competition between species in the re-colonization rates remain controversial. We investigate these different aspects with the CARAIB dynamic vegetation model (CARAIB DVM). Transient runs were performed over the Holocene using the HadCM3 AOGCM-reconstructed climate. European-wide species migration at 0.5° x 0.5° is represented in the model using migration rates derived from a high resolution cellular automaton, CATS-UPSCALE. Individual tree species migration rates were pre-calculated with CATS-UPSCALE every 1000 years over each grid cell used by the DVM in the climatic conditions reconstructed by the AOGCM. The impacts of competition on plant dispersal are not taken into account by the automaton. Thus, in CARAIB, a function has been constructed to reduce the potential CATS migration rates in competition conditions. It is based on the species dispersal kernel and on the net primary productivity of the different species present on the grid cell. The migration of one species, from its 10,000 BP refugia, is studied within a landscape defined by a set of other species for which no dispersal limitations are assumed. Here, we illustrate the results obtained for two wind-dispersed (Abies alba and Picea abies) and for a no wind-dispersed (Fagus sylvatica) tree species. The speeds and the paths of the postglacial spread obtained with the DVM are compared to the past distributions of the three species reconstructed from pollen and macrofossil data. The Holocene climate conditions simulated by the HadCM3 AOGCM do not constrain the European re-colonization of the studied species, except in Scandinavia at the beginning of the period for Picea abies. We observe that, during the past 10,000 years, species occupied regions where climate conditions were different from present observed species climate requirements, notably in the 10k species refugia. This result may imply that at present the species do not occupy their potential distribution area and thus that the postglacial re-colonization is not completed yet. We also show that species dispersal capacities cannot explain the observed species migration over the Holocene and that competition has played an important role. Indeed, when we use the potential migration rates (no competition), species spread too fast. [less ▲]

Today, state-of-the-art simulation packages in flexible multibody dynamics allow the high-fidelity analysis of industrial mechanisms and machines in many application fields including robotics, automotive systems, aeronautics, deployable structures or wind turbines. The dynamic response of a given system can thus be evaluated in the time-domain for given load cases and given initial values. However, in many practical cases, the engineer does not have a precise knowledge of the mechanical design, the loading conditions and the initial state. This situation occurs for example in structural optimization, optimal control, experimental identification and health monitoring problems. The complexity of simulation codes and the computational cost of high-fidelity models are still important obstacles for the development of efficient resolution methods for these inverse problems. A current challenge is thus to elaborate simplified and more efficient modelling strategies in flexible multibody dynamics in order to enable the development of inverse analysis methods. The talk is divided into three parts. The first part provides an overview of available simulation techniques for flexible mechanisms with a particular emphasis on finite element-based approaches and time integration methods. Some illustrations are presented in the fields of deployable structures, vehicle dynamics and wind turbines. In the second part, optimization problems in flexible multibody dynamics are addressed and solved using gradient-based methods. Efficient methods for sensitivity analysis are discussed and special problems are treated such as the structural optimization of mechanical components or the numerical solution of inverse dynamics problems. The third part discusses a recently-developed Lie group approach which allows the formulation of the equations of motion of a multibody system in a parameterization-free setting. Based on this general formalism, which is characterized by an increased modularity and a reduced complexity, a large variety of Lie group solvers are foreseen not only for time integration but also for model reduction, sensitivity analysis and optimization.

Methods validation is mandatory in order to assess the fitness of purpose of the developed analytical method. Of core importance at the end of the validation is the evaluation of the reliability of the individual results that will be generated during the routine application of the method. Regulatory guidelines provide a general framework to assess the validity of a method, but none address the issue of results reliability. In this study, a Bayesian approach is proposed to address this concern. Results reliability is defined here as “the probability ()π of an analytical method to provide analytical results within predefined acceptance limits ()X()λ± around their reference or conventional true concentration values ()Tμ over a defined concentration range and under given environmental and operating conditions.” By providing the minimum reliability probability (minπ needed for the subsequent routine application of the method, as well as specifications or acceptance limits ()λ±, the proposed Bayesian approach provides the effective probability of obtaining reliable future analytical results over the whole concentration range investigated. This is summarized in a single graph: the reliability profile. This Bayesian reliability profile is also compared to two frequentist approaches, the first one derived from the work of Dewé et al. [1] and the second proposed by Govaerts et al. [2]. Furthermore, the applicability of the Bayesian reliability profile is shown using as example the validation of a bioanalytical method dedicated to the determination of ketoglutaric acid (KG) and hydroxymethylfurfural (HMF) in human plasma by SPE-HPLC-UV.

Since the end of the eighties, the globalization and development of new information and communication technologies have played a great part in complicating exchanges between companies and their various stakeholders (staff, customers/users and business partners). New forms of organization of work result in more and more relationships between people of different nationalities and cultures. Thanks to virtuality, a lot of companies can develop connections with people from various cultural backgrounds which can be co-located or distributed (with partners situated abroad, including in different time zones). But to maximize this potential, organization must overcome different complexifications levels of virtual communication and multicultural. So, we suggest studying the impact of cultural diversity on the quality and efficiency of virtual communications. There are already many studies about the impact of diversity on non-virtual context but very little about the impact of diversity on virtual exchanges. The originality of this article is to focus on the influence of intercultural and virtuality. [less ▲]

As his star-spangled costume and his usually firm posturing suggest, Uncle Sam impersonates the United States and symbolically reflects the nation’s most cherished values and ideals such as freedom, exceptionalism, and (masculine) strength. As such, he connects the projects of nationalism and patriotism with the scale of the individual. In other words, he embodies the American motto ‘out of many, one.’ Steve Darnall and Alex Ross’s rewriting of the character, however, strongly contrast with this dominant perception of Uncle Sam in their eponymous 1997 graphic novel. Their narrative shows a distressed and lunatic homeless man wandering the streets of an unknown American city. As he roams the streets, he undergoes an identity crisis that coincides with a crisis of memory, both of which complicate the relation between the symbolic individual body and the collective American unconscious. On the one hand, the character represents the values of freedom and democracy that the US government has strived to implement. On the other, he realizes that the paradigm of the nation cannot be understood as a monolithic entity, and that the plurality of voices that inhabit his persona – and, quite paradoxically, the country – cannot uphold this meta-narrative of American unity. In asking whether or not Uncle Sam is one of U.S., Darnall and Ross comment on the paradoxes of freedom and the myth of the melting pot. [less ▲]
