The main feature of Discontinuous Galerkin (DG) methods is their ability to take into account discontinuities of the unknown field in the interior domain of studied problems. In such formulations the integration by parts is realized on the elements leading to boundary integral terms These terms between elements ensure the continuity and compatibility of the solution in a stable manner, which makes DG attractive to ensure weakly the C0 continuity and/or the C1 continuity. For non-linear Kirchhoff-Love shells, the C0/DG formulation - the C0 continuity is ensured as usual by considering continuous shape functions and the C1 continuity is weakly ensured by DG interface terms in a stable and consistent way - leads to a one-field formulation, where the displacements are the only unknowns of the problem [5]. DG methods have also an advantage when it comes to simulate fracture with a cohesive approach. Indeed, the classical cohesive methods suffer from severe limitations. The intrinsic approach, which inserts the cohesive elements at the beginning, requires an initial slope in the traction separation law and suffers from lack of consistency, while the extrinsic cohesive method, which inserts the cohesive elements during the simulation when a fracture criterion is reached, suffers from difficult parallel implementation due to the topological mesh modifications happening during the simulations. To overcome these limitations, new methods were developed and in particular, an approach based on a C0-discontinuous Galerkin formulation where continuity between elements is ensured weakly by the interface elements. These interface elements can be easily replaced by a cohesive element during the simulation, leading to an efficient fracture framework [4, 6]. We have recently extended this approach for linear shells [1] to obtain a full DG formulation of thin bodies, where discontinuities in the C0 and C1 fields are weakly enforced using consistent interface elements, and where the interface elements can be used to integrate the cohesive law when a fracture criterion is met. Moreover, a new cohesive law based on the reduced stresses of the thin bodies formulation is developed to propagate a fracture through the thickness. This cohesive model dissipates the right amount of energy during crack initiations and/or propagations. These developments are extended to non-linear elasto-plastic shells and are implemented in parallel, which allows to simulate complex fracture problems. As a validation example, the study of a blasted notched-cylinder is performed, for which experimental and numerical (by XFEM method) data are reported in the literature by [3]. Figure 1 illustrates the results obtained at different times. It can be seen that the simulation allows to model crack propagation, as well as the bifurcation happening when the crack reaches the top of the cylinder. Also, it appears that with the elasto-plastic framework, the crack speed numerically predicted matches the experimental measures [2]. [less ▲]

In the second part of the talk, I will present some applications of these methods to the following decidability question: given a DFA recognizing a set of integers represented in a fixed numeration system, decide whether this set is ultimately periodic. The techniques presented in this talk could be extended to other classes of sets of integers, and thus, could be applied to new decidability questions. [less ▲]

In this paper, we set out to determine whether the link between deliberation and transformation (or between process and outcome) is as straightforward as deliberative democracy assumes. More specifically, our research question is threefold: (1) whether a high quality of deliberation does indeed lead to changes in attitudes, (2) whether a high quality of deliberation can lead to a higher appreciation of the members of the outgroup, and above all (3) whether group composition matters. We thus want to push the research on the transformative effects a little further, into political psychology grounds, and see whether these effects can also take place in deliberation between diametrically opposed groups. Our aim is thus not only to test the link between deliberation and transformation, but also to see whether deliberation can have its transformative effects in high conflict settings, i.e. in more real-life settings. Based on findings from two deliberative experiments organized in deeply divided Belgium, we argue that the quality of deliberation (and the perceived quality of deliberation) are only weakly linked to changes in outgroup attitudes, and that the main variable explaining shifts towards more positive outgroup feelings is actually the group composition. Participants who are confronted with the other side are less likely to hold more negative views of the outgroup after the deliberation. [less ▲]

Carbon Capture and Utilization (CCU) has the potential to reduce both greenhouse gas emissions and fossil fuel use. However, the conversion of CO2 is intrinsically difficult due to its low energetic state. Thus, a positive environmental effect of a CO2-consuming reaction cannot be taken for granted. In this work, we therefore present a graphical method to identify promising reaction schemes using CO2 as a feedstock. Reactant mixtures leading to minimal life-cycle greenhouse gas (GHG) emissions are determined. The optimal reaction schemes strongly depend on the reactants’ global warming potential (GWP); in the case of CCU, the future GWP values of CO2 and H2 are particularly critical and subject to major uncertainty today. The graphical method therefore provides GWP targets for CO2 capture and H2 production technologies. The method is demonstrated for the production of methanol. Five optimal reaction schemes are identified depending on the GWP values of CO2 and H2. Thus, four threshold relations for the GWP of CO2 and H2 are derived showing directly under which conditions the utilization of CO2 as a feedstock is environmentally preferential. [less ▲]

Introduction. Today, it is considered that, in children with serious illnesses such as cancer, physical activity during treatment has beneficial effects (physical and mental well-being, self-confidence and self-esteem ...)(INSERM, 2008). However, it is important to notice that physical activity has to be appropriate according to the circumstances (Herbinet, 2002). If some programs begin now to be offered in some hospitals, a lack of resources suitable for children and adolescents appears to be the norm. This study aimed to identify needs and resources for the implementation of a project like this in the department of Hematology Oncology at a hospital in the region of Liege (Wallonia, Belgium). Methods. In this perspective, we interviewed various members of the medical and paramedical staff (n = 20), young patients (n = 8) and their parents (n = 5). This triangulation process aimed to guarantee the validity of the data. The semi-structured interviews were focused on the representations of these subjects about physical activity at the hospital in young people with cancer (definition of physical activity, opportunities and habits of the young patients to exercise, benefits and risks of being active) as well as about their opinions about the characteristics of the actions to implement (type of activities, recommendations, needed resources and conditions). Respecting the principles of the qualitative research, a content analysis of the answers has been conducted. Results. Most of the subjects supported this type of project. Five categories of activities have been identified (adapted ball games, soft gymnastics, group fitness classes, relaxation activities, outdoor activities). A daily medical monitoring has been emphasized while precautionary measures have been listed, as well as the resources of the human, material, organizational and financial aspects that would be needed.

In Israeli architectural history, both the official dominant position and the emerging critique usually trace the birth of Zionist comprehensive regional planning policy back to the 1930s and to the rise of the so-called Bauhaus-style modernist architecture and urban planning. Looking back to the early 1920s, the Jewish colonization of British Mandate Palestine experienced a major shift, turning from a sporadic and experimental phenomenon to a conscious mass strategy. The Zionist Organization and its many agencies gained a hegemonic role in driving the “Return of the Jewish people to the (Promised) Land” and to agriculture. Hence, Zionism faced for the first time the problem of establishing the forms and features of the Israeli Nation-Space.A key figure in this process was the German-born Jewish architect Richard Kauffmann (1887-1958), which planned most of the new agricultural and urban settlements promoted by the Zionist Organization in Palestine.Placing side by side each of Kauffmann’s plans, an early pre-State regional planning scheme emerges. One that envisioned the Jezreel Valley as the future “core” of the Israeli nation-state shaped as complex polycentric urban network. There, a new national identity based on social reform, agrarianism and the reinterpretation of local geographic possibilities would have developed along an “ancient-modern” transcontinental route between the Mediterranean and the Middle East. Discussing Kauffmann’s contribution to the architectural and landscape expression of this ambitious and controversial resettlement project against geopolitical, agricultural and ideological issues, an alternative narrative of Zionist modern architecture and planning might open up and present-day architectural and planning practice’s “lost of the centre” can be usefully questioned.

According to World Health Organisation, 80% of the African populations use Improved Traditional Medicines (ITM) to threat several diseases. Even if some of these ITM are nowadays registered with local health authorities, the knowledge of their qualitative and quantitative composition still remains a challenge for ensuring health security of populations. In this context, an analytical method using liquid chromatography technique with UV detection was developed to allow the dosage of a tracer (major compound) in an ITM (syrup containing extract plants) registered in D.R. Congo by the “Centre de Recherche en Médecine Traditionnelle Améliorée” and marketed for use against malaria. For that purpose, a simple and rapid experimental plan considering a Plackett-Burman design was applied by testing simultaneously two significant factors, temperature of analytical column (T°) and gradient time (TG) for eluting acetonitrile (ACN) from 5% to 95%, while focusing on the separation of the tracer and an adjacent unknown compound (critical peak pairs). Suitable separation (resolution of 1.5) was obtained between these latter with T° of 15°C and TG of 60 min (20% to 65% of ACN). Prior to routine use, the analytical method was validated following the total error strategy described by the SFSTP guidelines and according to the ISO norm 17025:2005. Specificity/selectivity of the method was demonstrated by the absence of interference at the retention time of the major compound comparing to the syrup matrix. Very interesting results were observed for trueness (relative biases below 0.9%), for precision (RSD mostly below 2.2% for repeatability and time-different intermediate precision), for accuracy (beta tolerance intervals below 10% of the acceptance limits) and linearity. Finally, the method was applied to quantify the major compound in several batches of syrups ITM as well as for stability studies. [less ▲]

Le thème du dialogue social en milieu carcéral est rarement étudié par les sociologues francophones en général (Froment, 1994) et belges en particulier. Paradoxalement, la Belgique connaît une solide tradition syndicale d’une part et, d’autre part, le pouvoir des organisations syndicales est reconnu par de nombreux acteurs du terrain carcéral (managers de l’administration pénitentiaire, directeurs de prison, surveillants, personnels socio-éducatifs, détenus, etc.). Aussi, les grèves au sein des prisons belges se sont multipliées ces dernières années, portant diverses revendications liées au « bien-être » des surveillants (sécurité au travail, horaires, rémunération, etc.) et réclamant une étude circonstanciée. Notre communication présente une étude empirique menée de juillet à octobre 2011 à la prison de Verviers (N = 25), qui fut alors le théâtre d’un mouvement social conclu par la fermeture de cet établissement. Cet événement permet de saisir concrètement les stratégies et discours des organisations syndicales, de l’administration pénitentiaire et des pouvoirs locaux. Cette étude de cas, en plus de combler un « vide » sociologique, vise à décrire et analyser les processus de négociation et de qualification à l’œuvre dans une situation de crise et à mettre en lumière les tentatives de réduction des incertitudes inhérentes au sort des surveillants (de Verviers et d’ailleurs) et à considérer les incertitudes (méconnues) liées au sort des détenus.

The mean-field homogenization (MFH) approach is an attractive framework for multiscale methods, as it provides predictions of the macroscopic behavior of particle or fiber reinforced composites at a reasonable computational cost. Efficient MFH methods have been available for a long time for linear elastic problems, using for example the Mori-Tanaka scheme [2], but they can also be extended in the non-linear regime after linearization of the constitutive behavior at the current strain state, as for the incremental approach, e.g. [1]. In this work, the application of ductile-damage theories to a multiscale analysis of continuous fiber reinforced composites is considered. Toward this end, the incremental MFH approach is extended to account for the damage behavior happening in the matrix material at the microscale and to derive the effective properties of particle or fiber reinforced composites. However, capturing the degradation, damage or failure of material happening at the microscopic scale could lead to loss of uniqueness in the solution as the governing partial differential equations may lose ellipticity at a given level of loading corresponding to the strain-softening onset. Thus, in order to avoid the strain/damage localization caused by matrix material softening, the gradient-enhanced formulation [3] is adopted to describe the material behavior of the matrix during the homogenization process, as we have recently proposed [4]. As illustration, the behavior of a fiber re-enforced elasto-plastic matrix is considered. The properties of the matrix correspond to an elasto-plastic material experiencing damage, with a non-local form of Lemaitre Chaboche model. The fibers are assumed linear elastic, see [4] for details. A loading-unloading cycle is applied in the direction transverse to the fibers. A maximal deformation of 10 % is reached before the unloading proceeds to zero-transverse deformation. The effective behavior predicted by the MFH models is compared to the solutions obtained by finite element computations performed on a unit periodic cell and on RVE where the micro-structure is fully meshed. The results for three fiber volume ratios are presented in Fig. 1. For the three fiber volume ratios, the homogenized property is dominated by the properties of the matrix, with an obvious elasto-plastic behavior exhibiting softening. For vI = 15% and 30%, rather good predictions are given by the MFH model, with, as expected, higher macroscopic stress and damage predicted by the MFH due to the incremental formulation. However for vI = 50%, the MFH model overestimates the macroscopic stress considerably. This error comes from the assumption of Mori - Tanaka based MFH. As it is shown to be an efficient multi-scale approach, the developed gradient enhanced MFH formulation presented can now be used to model the behavior of composite laminates experiencing damage.

In multinational federations, identities are a chief variable of the political life. By definition, the ethno-linguistic identities play(ed) an important role in the federal dynamics of the country. In most cases, the institutional design is in fact adapted or has been adapted to the ethno-linguistic divisions of the country. According to quite a few scholars, it is especially true for political elites who are not only shaped by this variable but also use this variable to legitimate their attitudes and actions. Therefore political elites of each ethno-linguistic group appeared to behave as monolithic blocks, standing against each other along ethno-linguistic lines. Nonetheless, this view neglects the role of party interests in explaining the behaviors of political elites. An important question for multinational federations can be raised: do identities matter more that party interests? The current reform of the Belgian state provides a fertile ground to test this hypothesis. To what extent, party interests can account for political elites’ position in the debate about the 6th Belgian constitutional reform? To explore these questions, we surveyed every representative of Belgium’s seven legislative assemblies with a standardized questionnaire (Summer 2011). This research will help us apprehend the rationale behind political elites’ attitudes – be it identities, party interests or a mix of them – negotiating the new boundaries of the state. [less ▲]

The present study aims at assessing consequences of salinization during the last three decades in this estuary with regard to land, biodiversity and water degradation. In this respect, Landsat images (1984, 1992, 1999 and 2010) were used to investigate regional time series land use/land cover. These were classified into six land-use/land-cover types: water bodies, high mangrove, low mangrove, denuded and salty soils (locally called “Tan”), savannah/rainfed agriculture and forestland. Change detection analysis of land and mangrove degradation was assessed using GIS techniques. Spectral analysis indicated that from 1984 to 2010, mangroves and savannah/rainfed agriculture are converted to “tan” (denuded and salty soils). In addition, these results showed that significant changes in land-use/land-cover occur within the whole estuary system and reflecting therefore environmental degradation, such as land desertification and salinization, and vegetation degradation which reflect the advanced of salinity [less ▲]

This paper probes the connections between Rainer Maria Rilke and Janet Frame, emphasizing the temperamental and aesthetic similarities linking the two writers, and examining in particular the differential quality which informs an approach to prose-writing characterized by its constant gesturing towards poetry. While Frame's recourse to a modernist idiom seems to privilege an intense focus on her own artistic medium, felt to be divorced from any easily recognizable existential reality, it can be shown that her linguistic utopia, unlike Rilke's, finally fails to incorporate the promise of a restoration of reference or 'fullness' that would follow upon its realization within the text.

What makes for an engaging song? One may credit the lyrics, another the melody, but in fact the two components are indissociable (Tatit, 2007). In Cole Porter's “Miss Otis Regrets”, we are introduced to the sad account of Miss Otis. The lyrics give us fragments of her story but not from her point of view. How, then, do we relate to her tragedy? In this paper, a comparative semiotic approach to lyrics, music, and voice will be used to demonstrate the narrator is key to this process. It is from the latter's point of view that we approach the story. First, an analysis of the linguistic component, based on Greimas (1983; 1987) and Zilberberg (1988; 2006), will show how the choice of vocabulary and repetitions subtly disagree with the values assumed by the community that condemns Miss Otis. However, non-linguistic components also play a central role. Following Tatit's (1997; 2007) proposals for the semiotic approach to songs, we will investigate how Porter's choices of accents, elongations and the exploration of pitch range emphasize the points that are most filled with emotions in the narrative. Melody and lyrics are shown to work together in the construction of the emotional connotations. Nonetheless, it is only when it is no longer in paper, but in the form of an actual execution, that the song may be said to move. We then explore the well-known rendition of Ella Fitzgerald. Despite the accompanying piano, we focus here on the voice as the place where linguistic and musical components meet. Our analysis compares the recording and the original score in order to assess the level of adequacy and change that the interpreter promoted. Variations in notes, stress, and rhythm may be shown to change the original direction dramatically, while others offer accentuated distinctions that were already in place. In all cases, the singer’s transformations take the song a step further in its emotional contents. Adopting this comparative semiotic approach, we reestablish the chain that extracts the emotions from the narrative, to the music, and to the voice, showing that the path that ensures the emotional attachment of the listener is in the integration of the three components: lyrics, music, and voice.

Objectif: Les études qui seront présentées visent la création et la validation de nouveaux outils informatisés d’évaluation des activités de la vie quotidienne. Cadre théorique : Les patients souffrant d’une psychopathologie rencontrent souvent des difficultés dans la vie quotidienne. Cependant, les outils actuels d’évaluation du fonctionnement dans la vie quotidienne (e.g., questionnaires, observations ou simulations d’activités) présentent une série de limites qui rendent ces outils peu prédictifs et représentatifs du fonctionnement. Méthode : Nous avons créé deux tâches informatisées d’évaluation du fonctionnement dans la vie quotidienne : une tâche de courses dans un supermarché (shopping) et une tâche multitasking de préparation d’une réunion. Ces tâches ont été soumises à plusieurs populations cliniques (i.e., souffrant de schizophrénie, d’un trouble bipolaire ou d’une dépendance alcoolique) qui ont été comparées à des groupes contrôles appariés. Les patients ont également été évalués avec des mesures cognitives, cliniques, et du statut fonctionnel. Résultats : Les deux tâches informatisées différenciaient les groupes de patients des groupes contrôles sur plusieurs variables communes, ainsi que spécifiques à chaque population. Les performances aux tâches étaient également hautement corrélées avec le fonctionnement cognitif, des variables cliniques et le statut fonctionnel. Enfin, les tâches ont également montré de bonnes capacités prédictives du statut fonctionnel. Conclusion : Les résultats des différentes études montrent que les tâches de shopping et de préparation d’une réunion peuvent être considérées comme de bons outils d’évaluation du niveau de fonctionnement quotidien pour différentes populations cliniques. Ces tâches pourraient également être utilisées dans un contexte de remédiation, tant pour des patients souffrant d’une psychopathologie que d’un trouble neurologique. [less ▲]

Central African rainforests are no longer considered as pristine, but as the outcome of a long history of changes due mainly to climatic variation. For the later part of the Holocene it has been hypothesised that climate changes together with human activities triggered modifications in terms of distribution and botanical composition. While developing a research project to explore the mechanisms of forest change, new research avenues for the archaeology of rainforests became apparent. In this paper, we outline the results of this approach, implemented on a forest concession (Cameroon). We introduce our methodology based on the analysis of botanical inventories (focused on large trees of human linked species and light demanding species), coupled to systematic core boring and test pits. A sampling strategy for the collection of charcoal and its identification is developed and archaeological remains found in association are analyzed at the Royal Museum for Central Africa. [less ▲]

Los primates son reservorios de patógenos humanos ya sea que estén en libertad o en cautiverio. Si identificamos los parásitos y las enfermedades que estos ocasionan en primates, sería una herramienta para su conservación y un aporte significativo para la salud pública. Colectamos e identificamos los parásitos gastrointestinales de 10 especies de primates de la Amazonía ecuatoriana. Se utilizo la técnica de flotación con solución de azúcar sobre saturada (d≈1.28 - 1.33) y la técnica de Ritchie. Las muestras fueron analizadas según factores extrínsecos e intrínsecos de los primates. Los valores generales de prevalencia para protozoarios y helmintos fueron de 17.6% y 55.4% respectivamente. Infecciones con un solo parásito fueron observadas en 46% de las muestras e infecciones con dos o más parásitos fueron observadas en tan solo 17.6% de las muestras. Las hembras tuvieron mayor prevalencia (93.33%) que los machos (68.75%). Más de la mitad de los parásitos encontrados en este estudio (Necator/Ancylostoma, Capillaria sp., Strongylus sp., Entamoeba histolytica, Hymenolepis sp., Oesophagostomum sp.) son una amenaza potencial de transmisión zoonótica. Lagothrix lagotricha tiene la mayor diversidad de parásitos (7) en comparación con las otras especies de primates estudiadas. Este estudio muestra una diversidad de parásitos de importancia zoonótica, lo cual demuestra el interés que deber presentarse tanto para el manejo de fauna silvestre como para programas de salud pública.

Eukaryotic genes have a mosaic structure of exons and introns. After transcription, precursor mRNAs have to be spliced to yield mature mRNAs suitable for protein synthesis. This process is termed splicing and is carried out by a complex known as the spliceosome. Serine/arginine-rich (SR) proteins play essential roles in splicing. They have a modular organization featuring at least one RNA recognition motif (RRM) domain and a carboxyl-terminal RS region enriched in arginine/serine dipeptides. However, their architectures are quite diverse, which has so far complicated their evolutionary analysis. To investigate the origin and evolution of SR splicing factors, we inferred phylogenies for more than 12,000 RRM domains representing more than 200 broadly sampled organisms. Our results show that all SR proteins share a single ancient origin. Based on refined analyses, we propose a scenario for their diversification into four natural families and a dozen subfamilies. Altogether, this work confirms the homogeneity and antiquity of SR splicing factors while establishing robust phylogenetic relationships between animal and plant proteins. In this talk, I will focus on the bioinformatics approaches required to carry out such a large-scale phylogenetic analysis. [less ▲]

Suppose the random vector (X,Y) satisfies the nonparametric regression model Y=m(X)+sigma(X)*epsilon where m(X) =E [Y|X] and sigma^2(X) = Var [Y|X] are unknown smooth functions and the error epsilon, with unknown distribution, is independent of the covariate X. The pair (X,Y) is subject to generalized bias selection and the response Y to right censoring. We define a new estimator for the cumulative distribution function of the error epsilon, where the estimators of m(.) and sigma^2(.) are obtained by extending the conditional estimation methods introduced in de Uña-Alvarez and Iglesias-Perez (2010). The asymptotic properties of the proposed estimator are established. A bootstrap technique is proposed to select the smoothing parameter involved in the procedure. Finally, this method is studied via extended simulations and applied to real data. [less ▲]

In Chlamydomonas reinhardtii, prolonged anaerobiosis leads to the expression of various fermentative pathways. Among them, oxygen-sensitive hydrogenases (hyd) catalyze the reduction of protons from reduced ferredoxin resulting in the production of molecular hydrogen. In this work, light-induced photosynthetic electron transfer after a prolonged dark-anaerobiosis period was studied by following the kinetics of chlorophyll fluorescence emission, P700 oxidation and proton-motive force formation and consumption during the first 3 seconds of illumination. We show that during the induction of photosynthesis, an hyd-dependent photosynthetic electron transfer operates at a maximal rate of 110 electrons per photosystem per second, that is about half the one measured in aerobiosis. The implication in this process of components of the linear, cyclic and chlororespiratory electron transfer pathways, as well as various electron sinks, are investigated thanks to the availability of mutants. In a next step, we screen an insertional mutant library (~3000 clones) on the basis of the fluorescence induction kinetics upon a shift from dark-anaerobiosis to light. Five mutants display the signature of mutants deficient for NADPH:PQ oxidoreductase or hyd activities. In particular, one is defective for hydrogenase HydG assembly factor. This mutant behaves exactly has the hydEF mutant, thus confirming that in vivo both the assembly factors are required for an efficient hydrogenase activity. [less ▲]

The Ramses project — developed at the University of Liège since 2006 — aims at building a richly annotated historical corpus of Late Egyptian texts and, more broadly, of all the written material whose linguistic registers attest Late Egyptian evolutionary features from the 18th dynasty down to the Third Intermediate Period (ca. 1350-700 BCE). It has been specially designed with the idea of having a tool specifically dedicated to research in Egyptian linguistics. The corpus includes, for each text, the relevant graphemic (hieroglyphic transcription with transliteration) and linguistic information (complete morpho-syntactic analysis) as well as a full set of meta-data (description and categorization of the corpus, plus bibliographical references). Starting in 2013, we will progressively provide online access to the Ramses corpus. From a technical point of view, Ramses is a relational database in SQL where the texts are represented and stored in XML. Currently, ca. 1350 texts have been included in the database and received multifaceted annotations: they have been encoded in hieroglyphic script, translated in French and/or English and received annotations for part-of-speech information, lemmatization, and morphological analysis. The corpus consists of slightly more than 300 000 words at the end of 2011 (and is expected to grow up to more than 1 million words in coming years), which amounts to ca. 8000 lemmata, 14 000 inflexions and 45 000 spellings. In this paper, we review the experience of the Ramses Project in building a richly annotated corpus of an ancient language with a complex writing system. A particular emphasis will be put on the new avenues of research that a tool like Ramses opens up for the study of ancient text languages. First, we present the state of the art in Egyptology and the reasons for launching such a project. Second, we introduce the editing software and the annotation scheme. Third, we present a series of case studies (study of classifiers; relation between the graphemic and morphological level; valency pattern alternation; diaphasic variation) in order to highlight the capabilities of the search engine and the new avenues that it opens up for research in Ancient Egyptian linguistics.

Cet article tente de répondre à la question suivante : « Est-ce que l’agriculture urbaine et périurbaine de Niamey peut satisfaire et approvisionner une demande urbaine toujours plus croissante ? ». Cette question de recherche est accompagnée d’un objectif secondaire essayant de démontrer l’importance de la diversité des systèmes de production permettant le développement de nombreuses cultures. Cette étude a été réalisée à partir de données secondaires provenant du Recensement Général de l’Agriculture et du Cheptel (RGAC), de l’Institut National de la Statistique (INS) et de la Direction Générale de la Statistique Agricole (DGSA). Après une présentation de la zone d’étude, les différents systèmes de production présents au sein de Niamey seront décrits et caractérisés. Les systèmes de production se regroupent au sein de deux catégories : agriculture pluviale et agriculture irriguée (riziculture irriguée ; maraîchage, arboriculture fruitière et riziculture pluviale et/ou irriguée ; maraîchage et arboriculture fruitière) (Seybou Y et Wada H, 2004). De plus, la production et les superficies agricoles de chaque spéculation seront introduites. L’importance de la consommation alimentaire telle que celle des légumes (31,5 kg/personne/an) et des céréales (179,6 kg/personne/an) sera présentée afin d’établir une balance entre la production locale et les besoins alimentaires des ménages de la Communauté Urbaine de Niamey (CUN) (République du Niger, 1994). Les potentialités de cette agriculture sont accentuées par la faible capacité de stockage et la détérioration lors du transport des produits agricoles provenant des zones rurales. Il en ressort que malgré les fortes potentialités de cette agriculture de proximité (urbaine, périurbaine et rurbaine), certaines contraintes telles que la problématique foncière, l’accès aux intrants et aux matériels agricoles (motopompes) empêchent l’expansion de ces systèmes de production. De plus, les balances alimentaires présentées indiquent un déficit pour la quasi-totalité des rubriques alimentaires entraînant de ce fait un accroissement du coût des produits importés. Toutefois, les systèmes de production pourraient partiellement combler une demande alimentaire de la population en constante augmentation. [less ▲]

Un système de numération, comme notre système décimal usuel, peut être vu comme une bijection entre l'ensemble des entiers naturels et le langage formé des représentations de ces entiers. Lorsque l'on considère, de façon générale, une numération basée sur une suite strictement croissante d'entiers et pour laquelle les représentations sont obtenues par un algorithme glouton, la bijection qui à un entier associe sa représentation préserve l'ordre naturel. Ainsi, un système de numération abstrait est la donnée d'un langage L infini (le plus souvent régulier) ordonné par ordre généalogique croissant. L'entier n est alors représenté par le n-ième mot du langage L. L'introduction, il y a une dizaine d'années, de ces systèmes abstraits a été motivée par le théorème de Cobham de 1969 qui s'intéresse aux ensembles reconnaissables d'entiers. Un ensemble X d'entiers est dit S-reconnaissable, pour une numération fixée S, si l'ensemble des représentations dans le système S des éléments de X forme un langage régulier. Ainsi les ensembles S-reconnaissables sont, d'un certain point de vue, particulièrement simples puisque décrits par un automate fini. Le théorème de Cobham stipule que les seuls ensembles d'entiers simultanément reconnaissables pour deux bases entières k et l suffisamment indépendantes, à savoir multiplicativement indépendantes, sont exactement les unions finies de progressions arithmétiques. Ce théorème a été le point de départ de nombreux travaux de recherche au cours de ces quarante dernières années (généralisations à des numérations non standards, à plusieurs dimensions, formalisme logique,... ). Dans ce survol liant théorie élémentaire des nombres et théorie des automates, nous nous proposons de présenter quelques questions et développements en lien directe avec cette question générale : existe-t-il un lien entre les propriétés arithmétiques des nombres (e.g., carré parfait, nombre premier, critère de divisibilité, ...) et les propriétés syntaxiques de leurs représentations ? Les propriétés décrites par automates finis sont-elles, par exemple, stables en appliquant des opérations arithmétiques élémentaires comme l'addition ou la multiplication par une constante ? Les automates permettent également de tracer des liens avec la combinatoire des mots (suites automatiques au sens d'Allouche et Shallit et plus généralement mots morphiques engendrés par substitution) ou d'exprimer certains problèmes de décision dont la solution revient à étudier la complexité en nombre d'états (state complexity) de certaines familles de langages.

Parmi les nouvelles familles, celles recomposées peuvent présenter différents gradients de complexité et de diversité. Les familles homoparentales recomposées présentent une série de défis communs aux familles hétéroparentales recomposées : stress lié à la séparation/divorce, gestion des pertes/réorganisation, construction de nouvelles appartenances, etc. Toutefois, lorsque la souffrance s’invite dans le système, fréquemment d’abord remarquée chez l’enfant, il semble intéressant de prendre en considération non seulement la difficulté pour la famille à gérer les transitions critiques mais aussi l'impact de facteurs plus spécifiques aux familles homoparentales : homonégativité sociale, ambiguïté relationnelle, manque de support de la famille d’origine et des réseaux, etc. A travers une analyse de deux cas cliniques contrastés, une famille homoparentale recomposée et une hétéroparentale recomposée, nous essayerons de faire émerger les similarités et les différences cliniques. Quant au travail thérapeutique, tout en tenant compte de la spécificité de ces deux configurations familiales, il visera à créer un espace de gestion des transitions critiques entraînant des mouvements d’oscillation affective entre ce qui reste stable et ce qui est à réinventer. Apprendre à gérer la multiplicité des appartenances et à définir différentes identités familiales semblent être des objectifs majeurs et ce, pour l’intervention avec toute famille dite nouvelle.

L’intervention, effectuée avec le Dr Mauroy (ONE), a porté sur le rôle que jouent les professionnels dans les services EAJE et le regard qu’ils peuvent partager sur le développement et le bien-être du jeune enfant et des attentes des parents lorsque l’enfant est accueilli en dehors de sa famille. Lorsqu’un professionnel est confronté à la situation d’un enfant qui arrive dans la structure avec un handicap connu, il peut aborder plus facilement les besoins spécifiques de l’enfant et s’engager, avec les parents, dans une relation constructive dans laquelle chacun visera à établir une communication la plus transparente possible. Mais lorsqu’aucun problème de santé ni de développement n’est a priori signalé et qu’au fil du séjour, il relève des indicateurs « hors norme » à propos du développement de l’enfant, le professionnel fait face à des questionnements éthiques qui gagnent à être mis à plat, discutés et partagés en équipe (à l’interne du service, mais également avec les partenaires extérieurs). L’exposé a tenté de proposer quelques pistes de réflexion autour de ces questions, en posant un focus important sur l’observation professionnelle de l’enfant : quelles observations ? dans quel cadre ? quel retour aux parents ? qui effectue ce retour ? sous quelles formes ? Quelles attitudes attendues des professionnels de l’enfance ? [less ▲]

About 20 years ago, we proposed an innovative approach to data mining based on a blend of Boolean techniques and combinatorial optimization. The basic tenets of this approach were presented in a joint paper co-authored with Toshihide Ibaraki and myself. It was subsequently developed by Peter Hammer and his coworkers into a new broad area of research, dubbed Logical Analysis of Data, or LAD for short. The effectiveness of the LAD methodology has been validated by many successful applications to real-life data analysis problems. In a first part of this lecture, I will propose a brief overview of some fundamental Boolean models and of illustrative applications arising in computer science, in optimization and in game theory. I will next turn to a presentation of the basic principles of LAD and of some of the theoretical questions that have been investigated in connection with this methodology. This part of the lecture should allow the audience to place the development of LAD in a historical perspective. [less ▲]

In the last few years, polymer carbon nanotubes (CNTs) nanocomposites foams have received increasing attention due to their potential applications in electrostatic dissipation (ESD) and in electromagnetic interferences (EMI) shielding. To be efficient, these foams must exhibit appropriate electrical conductivity (> 1 S/m) and dielectric constant. A good understanding of the influence of the foam structural parameters on the electrical properties of the foam will ultimately enable the optimum design of these materials for the targeted applications. A wide range of poly(methyl methacrylate) (PMMA)/CNTs nanocomposites foams were synthesized using the supercritical CO2 technology. Different foaming parameters, such as the temperature, impregnation pressure, time and rate of depressurization were varied to modify the foam structure. The amount of carbon nanotubes in PMMA plays the most important role in increasing the electrical conductivity. Nanocomposite foams show higher electrical conductivity than non-foamed nanocomposites at the same volume content of CNTs. Effects of foam morphology such as cell-density; pore size, volume expansion, and cell-wall thickness on electrical conductivity were comprehensively assessed. High electrical conductivity can be achieved with nanocomposite foams that have high volume expansion, small pore size, high cell density, and thin cell-walls [less ▲]

L'avènement de l'agriculture, la sédentarisation de l'homme dans des villages, l'extension de ces derniers au point de devenir des villes de taille sans cesse croissante sont autant de phénomènes augmentant l'emprise de l'homme sur les ressources naturelles et participant à la dynamique paysagère (Mazoyer et Roudart, 1997). Le phénomène n'est pas négligeable: aujourd'hui, le nombre de personnes vivant dans ce qu'on désigne sous le terme de "ville" a dépassé celui des personnes vivant en dehors (United Nations, 2007). Il convient donc d'étudier en profondeur les conséquences de ce processus qu'est l'urbanisation et de les quantifier (Alberti, 2008). En particulier, la périurbanisation, caractérisée par une expansion diffuse de la ville dans un milieu mitoyen gardant son caractère rural, est au cœur des préoccupations de part sa position stratégique entre des espaces fortement et nettement moins anthropisés (Hervoët, 2001). Toute étude scientifique doit commencer par la délimitation du système étudié (Grimm et al., 2003). Paradoxalement, une synthèse bibliographique récente démontre qu'il n'existe pas de consensus sur le nombre de zones rencontrées dans ce gradient ni sur les définitions et caractéristiques de chacune de ces zones. L'article conclu qu'en vue d'une identification spatiale des zones à l'aide de la télédétection, il est préférable d'utiliser préférentiellement les caractéristiques morphologiques qu'il convient de traduire sous forme d'indices de structure spatiale permettant l'implémentation pratique des définitions données aux zones (André et al., en préparation). Suite à cette constatation, la présente contribution présente une méthode de segmentation du gradient urbain-rural qui s'appuie sur des éléments et indices paysagers décrivant la composition et la structure paysagères. Ces indices illustrent sous forme quantifiable les caractéristiques morphologiques les plus couramment citées pour décrire les différentes zones situées dans le gradient. [less ▲]

L’analyse d’une vingtaine de monographies publiées entre 1966 et 1986 permet de voir en quels termes les critiques favorables à la consécration du nouveau roman latino-américain d’une part et ceux qui leur sont réticents d’autre part, expliquent le succès rencontré par les ‘nouveaux romanciers’ en dehors de leur continent. Les critiques ‘positifs’ considèrent que la prose a abandonné la périphérie internationale. Selon eux, ce déplacement est tributaire de la fin de la ‘balcanisation’ littéraire du continent ainsi que de la qualité intrinsèque des textes. Cependant, les informations que leurs propres monographies communiquent d’une façon plus implicite permettent de nuancer certaines de leurs affirmations, notamment à propos de la fin des littératures nationales en Amérique latine et de l’émancipation littéraire vis-à-vis des modèles étrangers. Les monographies qui examinent la mondialisation du nouveau roman latino-américain avec un regard critique insistent, au contraire, sur une série de nouvelles dépendances que ce succès implique pour l’écrivain latino-américain, non seulement du point de vue des normes littéraires mais aussi de celui du marché. De là leur préférence pour et adhésion au terme ‘boom’. [less ▲]

El presente trabajo se propone analizar la conformación del mercado de semilla de soja transgénica en la Argentina desde la perspectiva de la nueva sociología de la ciencia (Frickel y Moore 2006) y la comercialización de la ciencia (Mirowsky y Sent 2008), en diálogo con la teoría de los sistemas mundiales (Hall 2000; Chase-Dunn 2006). Estos marcos pueden considerarse compatibles y mutuamente iluminadores para analizar desarrollos científico-tecnológicos en países periféricos y semi-periféricos en décadas recientes, en la medida en que permiten describir relaciones y mecanismos de poder entre sectores sociales y países, en momentos en que los desarrollos son llevados al mercado fundamentalmente, aunque no exclusivamente, por empresas transnacionales. La Argentina fue el segundo país en adoptar cultivos transgénicos, detrás de Estados Unidos y delante de Canadá, por su rápida adopción de la soja tolerante a glifosato, que fue aprobada en 1996. Un conjunto de circunstancias excepcionales favorecieron esta incorporación: el hecho de que la patente del glifosato ya hubiera expirado; la existencia de un sistema regulatorio de la biotecnología agrícola, montado cinco años antes; la tarea de promoción de esta tecnología por parte de las empresas involucradas, asociaciones de productores y extensionistas del sistema público; la incorporación simultánea de la tecnología de siembra directa; el aumento de la demanda internacional de soja, entre otros. Otro elemento clave fue la imposibilidad para la transnacional Monsanto de patentar el evento en el país. Esto determinó el bajo precio de esta tecnología en el mercado argentino en comparación con la semilla convencional y con la semilla de soja transgénica en el mercado norteamericano. También facilitó la participación de otras empresas; previsiblemente, transnacionales pero también nacionales. Entre las transnacionales, se destacó el papel de un fitomejorador, cuyos aportes son considerados por muchos actores cercanos al proceso, de vital importancia para la temprana incorporación de la tecnología. Esta circunstancia tuvo varias consecuencias: además de la rápida incorporación del evento a germoplasma de soja adaptado a las condiciones locales, una distribución de la renta derivada de este desarrollo que favoreció a los productores locales, y el fortalecimiento de la competitividad de la producción argentina en el mercado internacional de soja. En nuestro análisis, la conformación del mercado de semilla de soja transgénica en la Argentina representa un caso revelador en relación con los mecanismos, paradojas y contradicciones que se suscitan en países periféricos y semi-periféricos en la nueva etapa de la comercialización de la ciencia y la bioeconomía.

En partant d'une étude de cas, à savoir la construction et la diffusion médiatique d'une génération d'écrivains latino-américains, cette communication vise à analyser la manière dont la culture de la célébrité reconfigure les mécanismes traditionnels de production et de consécration littéraire. Pour cela, nous analyserons les dispositifs de médiatisation que la culture de la célébrité met en oeuvre pour produire un effet de notoriété et une légitimité médiatique. [less ▲]
