A simple relaxation consisting of two rows of a simplex tableau is a mixed-integer set with two equations, two free integer variables, and nonnegative continuous variables. Recently, Andersen et al. and Cornuéjols and Margot showed that the facet- defining inequalities of this set are either split cuts or intersection cuts obtained from lattice-free triangles and quadrilaterals. From an example given by Cook, Kannan and Schrijver it is known that one particular class of facet-defining triangle inequality does not have finite split rank. In this talk we show that all other facet-defining triangle and quadrilateral inequalities have finite split rank. [less ▲]

Through analysis and an attempt to assess the system developed at the level of the Wallonia-Europe Academy in the context of Center for Higher Didactics (Centre de Didactique Supérieure : CDS), the purpose of this article is to reflect on the specificities and constraints of a training limited to teachers in charge of First Generation students, those specificities being especially constraining since the CDS training sessions take place in a larger context : the training of all the university teachers. The Liege experience enlightens some determinant factors : sensitizing first on the interest of such a training, centring the training on close coaching of students learning with a focus on their difficulties or deficiencies and with help given to teachers in resolving them, meeting the diversity of the situations lived by those teachers (notably in terms of students number and disciplines), taking into account their expectations in accordance with their profile, cleverly combining oral speeches, testimonies and debates, suggesting a diversity of concrete intervention trails… By the way, the joined organization of introduction sessions and close coaching seminars seems to be a relevant formula in order to meet such kind of objectives.

Mixtures of trees can be used to model any multivariate distributions. In this work the possibility to learn these models from data by causal learning is explored. The algorithm developed aims at approximating all first order relationships between pairs of variables by a mixture of a given size.

In this paper we will make a brief presentation of ESCWA’s Social Guide for Urban Observatories (SGUO), then we will provide a commented example of application of its indicators’ framework. We will try to identify the essential determinants leading to the development of urban fragmentation. The SGUO indicators’ framework is a problem-based one. It aims to identify the determining conditions leading to the development of an urban “problem” and its impact on sustainable urban development. The author thinks of the SGUO indicators’ framework methodology as a building site in progress. On one hand, there’s still need to develop some of its theoretical framework components, mainly the concept of determinants. On the other, it should be revisited, in a participatory way. A primary application in a set of different urban observatories in the ESCWA region is needed in order to adapt it to the specificities of the region’s urban problems and local conceptions of sustainable development.

Super Ensemble (SE) techniques have recently allowed improving the forecast of various important oceanographic parameters, such as the significant wave height, the speed of sound or the surface drift, by correcting the prediction at a single or multiple locations, where data were available during the whole training period. However, nowadays common observation systems, such as satellite imagery or drifters, do not always provide information at the exact same locations, hence it is necessary to generalize the approach in order to take benefit of every image or track available. In this study, we try and apply a SE, fed with remote sensing and gliders data, to 3-D hydrodynamic models. The basic idea on which rely the SE methods is that a certain combination of several model runs and possibly data could yield better results than just one single model, even if it has a higher temporal or spatial resolution. As the most efficient techniques are the ones using observations, they rapidly developed and increased in complexity by copying what had been done in the data assimilation community; getting from the simple ensemble mean of the model outputs to their linear combination based on a particle filter. In our present study, we have decided to use the Kalman filter (KF) as it alleviates the need of an a priori determination of the training period length, and does not require the run of a very large ensemble of members. In addition, we apply it in a 3-D framework in order to take benefit of the spatial information contained by each source of measurements. For example, satellite images of sea surface temperature (SST) are very useful to correct the value of this parameter, but depending on the structure of the water column, it can also give a precious guess of how warm or cold is the ocean at 20 m deep. In our experiment the domain of interest is the Ligurian Sea during the last week of September, when part of the set-up for the CalVal08 campaign (SiC Charles Trees) had already taken place. The data assimilated during the training of the filter are SST images from AVHRR, as well as temperature and salinity profiles from two Rutgers University gliders. The models used for the study are three nested models of NCOM, run without data assimilation. The two considered variables are the temperature and the salinity. As our method is designed to work in a multivariate way, salinity forecast can possibly be improved by observing temperature profiles. Statistics are computed for both the training and the testing periods with an independent set of data. In four test cases, we review the impact of both the nature of the assimilated data, and the formulation of the model covariance matrix. At the end, we show that, on the basis of previous model outputs from which we’ve drawn an estimate of the model covariance, RMS error of the forecast in the whole 3-D domain can be reduced by 30%, thanks to the only assimilation of satellite SST images.

La dyspraxie développementale se manifeste principalement par des difficultés motrices qui interfèrent avec différentes situations de la vie quotidienne (écriture, dessin, habillage, …). Ces troubles du geste, qui touchent environ 6 % des enfants de 5 à 11 ans, entraînent de lourdes conséquences sur les plans familial, scolaire et social. Plusieurs études ont montré qu’un déficit des capacités d’inhibition, de planification et de mémoire de travail était fréquemment observé chez les enfants souffrant de dyspraxie. Toutefois, en raison des nombreux problèmes méthodologiques rencontrés dans ces recherches (et plus particulièrement liés à l’absence de contrôle de la présence ou non du trouble de l’attention avec/sans hyperactivité – TDA/H - chez la population d’enfants dyspraxiques), les relations entre les troubles attentionnels et les troubles moteurs restent encore à l’heure actuelle mal comprises. L’objectif de cette étude vise à dégager, au travers d’une évaluation du fonctionnement attentionnel et exécutif, le profil neuropsychologique d’enfants diagnostiqués dyspraxiques, et ce en contrôlant la présence d’un TDA/H. Nous avons administré à 23 enfants dyspraxiques âgés de 6 à 12 ans et 23 enfants de contrôle (appariés sur base de l’âge, du sexe et du niveau d’études des parents) des tâches attentionnelles (alerte, attention sélective et divisée) de la batterie TEA et des épreuves exécutives (inhibition [Stroop et Go/No Go], flexibilité cognitive [TEA], mémoire de travail [BTT et mise à jour de TEA] et planification [Tour de Londres]). Les analyses de comparaison de moyennes indiquent que les enfants dyspraxiques présentent des performances inférieures à celles des enfants de contrôle pour l’essentiel des tests neuropsychologiques administrés. Toutefois, deux tiers des enfants dyspraxiques de notre échantillon présentent un trouble de l’attention (critères du DSM-IV). L’analyse des résultats au sein du groupe « dyspraxique sans TDA », permet de montrer que les difficultés de planification, d’attention sélective visuelle, d’inhibition motrice, de mémoire à court terme (BTT et mise à jour) sont spécifiques à la dyspraxie et donc indépendant de la présence d’un trouble de l’attention. En conclusion, cette étude préliminaire montre qu’une grande proportion d’enfants qui présentent une dyspraxie souffre également d’un trouble de l’attention. L’analyse du profil des enfants dyspraxiques montre des difficultés qui touchent l’ensemble des fonctions attentionnelles et exécutives. Toutefois, les difficultés d’analyse visuelle, de planification et de mémoire de travail semblent, quant à elles, spécifiques à la dyspraxie développementale. Des études futures réalisées sur un plus grand nombre de participants permettraient de confirmer cette hypothèse. [less ▲]

The objective of this paper is to present the methodological developments in the DIDAM (Disaggregated demand and assignment models for combined passengers and freight transport) research project, which aims at advancing fundamental research in transportation modelling and analysis, using two complementary methodologies. The first is to develop a joint methodological approach for both freight and passenger transport, and the second is to base this common approach on the use of models that are as disaggregate and realistic as possible. Furthermore, the methods will be designed to cope with the important question of competition for infrastructure. The project is mainly organized around two themes. Each of them covers both freight and passengers aspects, in a manner which promotes collaborative work between the partners of the project. The first theme is concerned with disaggregate demand modelling issues, the second deals with innovative aspects of (joint) traffic assignment. Working at a fully disaggregate level is however not always easy. If such models are already available for passenger demand and traffic, disaggregate tools are still largely missing for freight transport. This is not only true at the operational level, but, more crucially, at the conceptual level. This is why our research program adopts, in this domain, a progressive approach that introduces disaggregation gradually into existing methods and models. This entails research in a full spectrum of issues, ranging from concepts definition (who are the actors, how can they be characterized ...) to validation exercises using available data sources [less ▲]

L’agriculture familiale africaine est concernée directement par l’Objectif 1 du Millénaire pour le Développement, de réduire de moitié d’ici 2015 l’extrême pauvreté et la faim. En effet, selon la plupart des observateurs, 70% des pauvres sont localisés dans les zones rurales et sont agriculteurs. Dans ce contexte, il importe de s’interroger sur l’avenir des exploitations agricoles familiales en Afrique. Après avoir présenté la problématique générale de l’exploitation agricole familiale dans le développement, les auteurs présentent une analyse au départ des constats qu’ils ont pu réaliser, respectivement pour les filières de rente de la zone forestière au Cameroun et pour le coton, dans plusieurs pays d’Afrique de l’Ouest. Les analyses sont réalisées à partir des observations effectuées au départ de différentes études financées essentiellement par la Commission européenne au cours de ces dernières années. Il en résulte que le terme « agriculture familiale » recouvre des réalités très différentes avec une différenciation de plus en plus poussée des exploitations agricoles. Dans le même temps, il subsiste de nombreuses exploitations familiales plus « traditionnelles » mêlant des logiques d’autoconsommation et de marché avec des dotations en facteurs plus inégales et donc plus vulnérables. L’enjeu primordial des politiques agricoles qui seront définies sera précisément de prendre en considération la dimension spécifique de ce type d’exploitation, cible prioritaire dans la lutte contre la pauvreté. L’orientation des politiques mises en œuvre autour du seul objectif de la production de biens agricoles ne permettra pas de réduire les disparités internes et souvent croissantes observées. Il convient donc d’intégrer les dimensions sociales et environnementales dans les objectifs des politiques agricoles à mettre en œuvre. [less ▲]

In this paper, we address the issue of the future of a particular field of research in social science: Science and Technology Studies (STS). Although this is a very young research field, its history is already diverse and its evolutions are fastly moving on. Its rapid expansion and its characteristic feature of crossing disciplinary boundaries are making it an interesting case to study, which takes a particular place in the overall history – and future – of social changes. As we shall indicate, STS have an increasing committment for the resolution of sociotechnical controversies. In this paper, we problematise this particular position by underlying the implicit politics of STS research and how they will shape the future of that particular field. Our approach is threefold. First, we give a brief overview of the history of the field and we point out the main evolutions since the developement of the Social Construction of Technology approach (SCOT) in the 1980s that long influenced the field. By doing so, we underline the epistemological critical tradition that gave the field some of its particularities that we address. We show how this tradition brought important insights of “political” nature within the development of the field. Second, our ambition is to highlight new patterns of evolution of the STS field, emphasizing the trends towards both a greater depoliticisation and a more engaged research. By “depoliticisation”, we intend to analyse the dynamics of institutionalisation of the field which adopts resources and tools to legitimate itself among the social scientific community. By “engaged” research, we will explore the evolutions of the STS field as inherently political. The field does have an implicit statement in favor of changing social order and an increasing willingness to actually influence that social change. In that respect, research projects in STS often have underlying politics, as we shall demonstrate. Third, we give a concrete example of these new patterns occuring, relying on the growing importance of nanotechnologies, both in the STS literature and research projects. We consider this case study to be intertwined with the development of STS as a field of research. In that sense, we stress that nanotechnologies happened to be a powerful tool for legitimation for the STS community. Therefore, we — as STS scholars — suggest instrumentalizing the interest we have in nanotechnologies in order to observe the evolutions of our field of research. Then, nanotechnologies will constitute an interesting ground to perform a test that will show depoliticisation and engagement as patterning the STS field. [less ▲]

Purpose: Print 3G is a peptidic antagonist of oncoprotein involved in breast cancer, containing 25 amino acids. The purpose of this work is to study the peptide encapsulation into PEGylated liposomes composed of SPC:CHOL:mPEG-2000-DSPE (47:47:6). Methods: Loaded unilamellar vesicles were prepared by hydration of lipid film method. Unfortunately, a loss of Print 3G was observed during the different steps of this manufacturing technique giving rise to encapsulation efficiencies (EE) close to 0 %. Thus, the freeze-thawing method was used to enhance the amount of Print 3G encapsulated into blank liposomes prepared using the above procedure. Because many factors may influence the peptide entrapment into the vesicles (number of freeze-thawing cycles (NC), lipid concentration (LC), peptide concentration (PC) and mixing time (MT)), a design of experiment (DOE) was performed (for the screening, a Plackett and Burman plan; for the optimization, a central composite design). EE were calculated in terms of quantity of peptide loaded in liposomes as a function of quantity operated (EEp) or quantity of lipids (EEl). Results: The EE obtained by the freeze-thawing method in standard conditions (Katanasaka, Ida et al., 2008; Maeda, Bharate et al., 2008), amounted to 26.20 ± 7.98 %, n=3 (EEp) and to 0.26 ± 0.074 % (EEl). Among the different considered parameters, the screening permitted to identify two factors having a positive and significant influence on the EE: NC and LC. Concerning the PC and MT, no influence was revealed. For the second part of the DOE, the positive factors were optimized and obtained results revealed a theoretical optimum at 64.75 ± 3.55 % when 11 freeze-thawing cycles were applied (NC) and for the following LC: 36.1 mM SPC, 36.1 mM CHOL and 4mM mPEG-2000-DSPE. The experimental results showed an encapsulation efficiency of 62.68 ± 2.93 %. Photon correlation spectroscopy and freeze-fracture electron microscopy were also realized to examine the liposome integrity, before and after the freeze-thawing cycles. Conclusion: Changing the manufacturing technique permitted a significant encapsulation of Print 3G into liposomes. The DOE led to a significant improvement of encapsulation efficiencies.

Cassini’s Ultraviolet Imaging Spectrograph (UVIS) has completed five years of study of Saturn’s atmosphere and auroras. Two long slit spectral channels are used to obtain EUV data from 56.3-118.2 nm and FUV data from 111.5-191.3 nm. 64 spatial pixels along each slit are combined with slit motion to construct spectral images of Saturn. Auroral emissions are seen from electron-excited molecular and atomic hydrogen. In 2008-2009 UVIS obtained data with the spacecraft well out of Saturn’s ring plane, permitting UVIS to obtain a number of short movies of the rotating auroral structures. In some movies a cusp-like feature is present near noon inside the oval. One movie from 2008 day 201 shows parallel linear features on the day side almost at right angles to the main auroral oval that appear, then lengthen, separate in the middle, and then fade away. The same movie also shows one bright "polar flare" inside the oval. A few of the most recent images were obtained at sufficiently close range that 2 spacecraft slews were needed to completely cover the oval. These images provide almost 100 pixels of information across the oval and clearly show multiple arcs of emission on the main oval and scattered emissions inside the oval. We will discuss these features, their locations, and possible interpretations. We also report on a search for an Enceladus auroral footprint on Saturn. [less ▲]
