This study formulates an itinerary choice model that is consistent with those used by industry and corrects for price endogeneity using a control function that uses several types of instrumental variables. We estimate our models using database of more than 3 million tickets provided by the Airlines Reporting Corporation. Results based on Continental U.S. markets for May 2013 departures show that models that fail to account for price endogeneity overestimate customers’ value of time and result in biased price estimates and incorrect pricing recommendations. Extensions to advanced discrete choice models show the importance of accounting for inter-alternative substitution for products that share similar departure times. [less ▲]

Public participation with science and technology (S&T) have often been criticized for risking to be either romanticized or instrumentalized. We propose to investigate the impacts of Responsible Research and Innovation’s emerging discourse on the legacy of the so-called ‘participatory turn’. More specifically, we aim to scrutinize the current promotion of Citizen Science at the European Commission related services. [less ▲]

This study aims to reconstruct the Holocene to modern depositional environments and the evolution over the main controls of the sedimentation along the northern coast of Sfax (Tunisia) using three sediment cores retrieved at 30 meters water depth by SEACNVS (Société d'Étude et d'Aménagement des Côtes Nord de la Ville de Sfax). The identification of different types of depositional environments was mainly based on field work,mineralogical and sedimentological analyses of core sediments. Mineralogical analysis by X-ray diffraction have been done on bulk powder and on oriented aggregate of the clay < 2 microns fraction,particle size distribution,magnetic susceptibility was measured on opened cores with a Bartington MS2Epoint sensor and Loss-On-Ignition (LOI) was measured after 24h at 105°C (water content, density), after 4h at 550°C (organic matter content) and after 2h at 950°C (inorganic carbonate).The mineralogical composition is made by clay minerals, quartz, calcite, gypsum and K-feldspar.The mineralogy of <2μm clay fraction show a mixture of kaolinite,illite, smectite and palygorskite. As harp change in the magnetic susceptibility profiles records the transition from a marine to a continental depositional environment. The marine domain is characterized by lower magnetic susceptibility values and coarser sedimentary grain than the continental domain. The vertical succession of depositional facies is made by two contrasted environments: a fluvial depositional environment (coastal plain) marked by channels and inundation plains at the in the lower section of all cores; a littoral marine environment characterized by fossil sand depositions in the upper section. The sand is rich in gastropods, lamellibranches, algæ and benthic fauna (Ammonia tepida, Ammonia beccarii, Elphidium crispum, Peneroplis pertususles Miliolidae, Peneroplis pertusus , Rosalina sp and Peneroplis planatus). This facies evolution indicates a relative sea-level rise which flooded the fluvial system at the coastal plain during the late Holocene. Results allowed the reconstruction of the Holocene shoreline variations along the northern coast of Sfax and complete the established records of sea-level fluctuations in southeast Tunisia during the last 10 000 years.

J’établirai un parallèle entre, d’une part, l’anthropologie linguistique de Hegel et, d’autre part, celles de Saussure et de Benveniste. Tous trois théorisent la langue comme une présupposition anthropologique. Chez chacun l’homme est ainsi essentiellement un être parlant, et sa tâche est de se reconnaître et connaître lui-même comme tel. Par là, tout « individualisme méthodique » est abandonné, l’homme ne peut se connaître comme individualité qu’à travers la médiation du langage, c’est-à-dire sur fond de l’universalité de la langue, qui par là même inclut la structure de l’Autre et de la communauté en elle.

Nous nous basons sur des outils informatiques – une vingtaine de blogues d’enseignants de Fle de l’espace européen – pour constituer le corpus et partons d’une réalité communicationnelle : le discours que le professeur tient sur son blogue a des traits spécifiques. L’analyse que nous proposons se fixe sur ces aspects. [less ▲]

Estetrol (E4) is a natural estrogen we recently characterized as a Selective Estrogen Receptor Modulator (SERM) with agonistic and antagonistic activities depending on target cells. We have also evidenced the functional importance of mixed estrogenic/anti-estrogenic activities of E4 in normal breast development and cancer. Recent molecular studies, indicating that progesterone receptor (PGR) functions as a molecular rheostat to control ERα chromatin binding and transcriptional activity, have revolutionized our mechanistic insights of steroid receptor activities in malignant breast. E4 is a promising candidate for hormone replacement therapy (HRT) at menopause. However, the impact of the combined use of E4 and progesterone on normal breast physiology and on breast cancer development has not been evaluated yet. To fill this gap, we will evaluate the impact of treatments of E4 and/or progesterone on mammary gland development and breast cancer risk as well as on established breast cancer cells. We will unravel the molecular mechanisms driving the dual estrogenic/anti-estrogenic feature of E4 alone or combined to progesterone by evaluating the putative contribution of the extranuclear ERα, of GPER and by studying the modulation of ER/PGR interactions. This study will be conducted thanks to international collaborations (INSERM Toulouse, Reims, CNRS Rennes, Curie Institute Paris) we established through the EU SEPTIME project we coordinate. Through this project, we will bring new insights to the intriguing dual estrogenic/anti-estrogenic activity of E4. We will bring rational data about the putative safety of HRT combining E4 and progesterone. The development of an animal model assessing the effect of HRT on breast cancer risk in menopaused mice will also provide a useful tool to evaluate the effect of new HRT candidates on breast cancer risk. Moreover, the potential anti-tumor synergism of E4 and progesterone would contribute to the evolution of breast cancer treatment. [less ▲]

Les enfants issus de milieux précarisés sont plus susceptibles de développer de faibles habiletés langagières (Hoff, 2003 ; Sylvestre & Mérette, 2012). En plus du milieu familial, l’environnement scolaire constitue un contexte privilégié pour prévenir certaines difficultés langagières (Dickinson, 2011). Les enfants peuvent y bénéficier d’interactions riches et diversifiées, tant avec les adultes qu’avec leurs pairs (Pence et al., 2008). C’est lorsque la qualité des interactions enseignant-enfant atteint un certain seuil que les effets bénéfiques sur les habiletés langagières seraient plus importants, surtout pour les enfants plus vulnérables (Burchinal et al., 2010). Or, la qualité de ces interactions - plus spécifiquement la qualité des stratégies de soutien au développement langagier - est très variable d’un milieu préscolaire à l’autre, selon des études québécoises (Bouchard et al., 2010 ; ISQ, 2014). De surcroît, la qualité serait plus faible dans les milieux défavorisés (Vandenbroeck, 2015). Cependant, aucune étude n’a été menée actuellement en Belgique francophone. L’objectif est de documenter la qualité des interactions et de l’utilisation de stratégies de soutien langagier par les enseignants dans les classes de deuxième maternelle en Wallonie/Bruxelles. Six enseignants de 2ème maternelle participent à la phase-pilote. Des observations in vivo et des enregistrements vidéo sont réalisés dans les classes, dans les conditions les plus naturelles possible. La qualité des interactions est évaluée à l’aide du CLASS® Pre-K (Classroom Assessment Scoring System®, Pianta et al., 2008). La Grille d’évaluation des interactions et des pratiques langagières de l’éducatrice (GEIPLE) est également complétée (Girolametto et al., 2002, traduite par Bouchard et al., 2010). Les résultats permettent d’engager une réflexion sur les modalités actuelles, et sur celles qu’il est possible d’implanter, pour mieux soutenir le développement langagier des enfants, et plus particulièrement des enfants en milieu précarisé, et d’émettre des recommandations relatives aux formations prodiguées aux enseignants.
