Dans le suivi de la recherche sur les formations initiales dans l'accueil de l'enfance (Pirard al., 2015), ce rapport présente le système éducatif et de formation au Québec ainsi qu'un programme de formation novateur mis en place au Collège d’enseignement général et professionnel (Cégep) de Saint-Hyacinthe depuis 2005. Ce programme, unique au Québec, vise à pallier aux difficultés de transfert des compétences des étudiantes en situation réelle complexe grâce à un accompagnement in situ des enseignantes centré sur les processus de la pratique réflexive. Ce rapport fait suite à la journée d'étude du 22 juin 2016 avec la contribution de la Pr Nathalie Bigras (Université du Québec à Montréal) et Lise Tétreau (enseignante au niveau collégial). [less ▲]

Mechanisms of interactions between groundwater bodies and rivers whose status and anthropogenic use can be detrimental from a quantitative and qualitative point of view to one or the other of these two compartments of the water cycle. In addition, contamination of groundwater by nitrate remains relevant. Based on these observations, a study financed by the Public Service of Wallonia was carried out over a period of 39 months to investigate (1) the direction, importance and dynamics of water exchange between groundwater and rivers at the scale of a river section; (2) the impact of these interactions on river baseflows and the river ecological status as a function of groundwater withdrawal and recharge at the catchment scale; (3) mechanisms and timing of transfer and abatement of pollutants (nitrate) between groundwater and surface waters at the watershed scale. The consequences of these mechanisms on the medium- and long-term evolution of groundwater and surface water quality were to be determined. To achieve this, the project relied on the implementation of a series of field investigations essentially focused on the interfaces between surface water and groundwater compartments (soil and unsaturated zone and water-table interface), while acquiring additional information on groundwater. The investigations carried out in the watersheds of the upstream Hoyoux and Triffoy watershed in the Condroz region aimed to provide 6 specific responses to water quantity and quality issued associated with groundwater – surface water interactions in the selected basins and generic responses in the form of new knowledge concerning the mechanisms of recharge and groundwater - river exchanges, concerning the evolution of nitrate concentrations in watersheds, data and measurements for the parameterization of models, and water resources management tools in the form of quantitative and qualitative indicators for groundwater - surface water interactions.

We report evidence for the electrochemical performances of two Li-ion full cells, built up by the combination of LiCo2/3Ni1/6Mn1/6O2 cathode material with MnSn2 intermetallic and Li4Ti5O12 spinel as the anode materials, respectively. MnSn2 and Li4Ti5O12 electrode materials illustrate different working voltage versus the redox couple Li+/Li0 and different reactionmechanisms during lithiuminsertion/deinsertion cycles. The structure,morphological characteristics and the electrochemical properties of the studied materialswere investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and electrochemical techniques. The two full-cell configurations showed different electrochemical behaviors. The MnSn2//LiCo2/3Ni1/6Mn1/6O2 configuration exhibits high working voltage (~3.5 V) and specific capacity (~200 mAh/gcathode) but suffers from high irreversible capacity loss during the first cycles and capacity fading during cycling. The Li4Ti5O12//LiCo2/3Ni1/6Mn1/6O2 cell demonstrated excellent cycling properties at different C-rates with 100% capacity retention after 150 cycles at 1 C. Although the working voltage (~2.2 V) and the specific capacity (~140 mAh/gcathode) are lower than those of the MnSn2//LiCo2/3Ni1/6Mn1/6O2 configuration, the other measured electrochemical properties suggest that the Li4Ti5O12//LiCo2/3Ni1/6Mn1/6O2 full cell is a potential candidate for battery application due to its excellent cycling performance and improved safety.

The sheepshead minnow Cyprinodon variegatus has become a favoured model for laboratory studies because of their small size, rapid development, and tolerance of laboratory conditions. Here, we analyse sheepshead minnow post-embryonic development with the goal of providing a generally useful method for staging fish after embryogenesis. Groups of three females and two males were placed in breeding chambers designed for this experiment. More than 100 eggs were collected and maintained in seawater. Embryos were selected under a dissection microscope and placed in incubation dishes (50 per dish) at 26 °C. On day six, embryos hatched and larvae were transferred to 1 L beakers. To define a simplified normalization table for sheepshead minnow development, we measured each fish for its standard length and examined the fish for four externally evident traits: pigmentation pattern, caudal fin morphology, anal fin morphology, and dorsal fin morphology. The four traits were chosen, because they are easily visualized with standard laboratory equipment such as the stereomicroscope and camera. We have provided criteria for staging sheepshead minnows in studies of post-embryonic development. Our data suggest that dorsal and anal fin morphology may serve as a useful phenotype for defining metamorphic climax stages throughout post-embryonic development in C. variegatus. The staging systems we propose should facilitate detailed anatomical and developmental analyses in relation to ecotoxicological studies on potential disruption of the thyroid axis by xenobiotics and endocrine-disrupting compounds.

The replenishment and persistence of marine species is contingent on dispersing larvae locating suitable habitat and surviving to a reproductive stage. Pelagic larvae rely on environmental cues to make behavioural decisions with chemical information being important for habitat selection at settlement. We explored the sensory world of crustaceans and fishes focusing on the impact anthropogenic alterations (ocean acidification, red soil, pesticide) have on conspecific chemical signals used by larvae for habitat selection. Crustacean (Stenopus hispidus) and fish (Chromis viridis) larvae recognized their conspecifics via chemical signals under control conditions. In the presence of acidified water, red soil or pesticide, the ability of larvae to chemically recognize conspecific cues was altered. Our study highlights that recruitment potential on coral reefs may decrease due to anthropogenic stressors. If so, populations of fishes and crustaceans will continue their rapid decline; larval recruitment will not replace and sustain the adult populations on degraded reefs. [less ▲]

By interrelating several texts on the editing and juxtaposition of heterogeneous images by the German essayist and media theorist Hans Magnus Enzensberger, this article brings up to date an aesthetic link between various past and contemporary media devices. The identification of this link makes it possible to free theoretical critique of the evolutionary paradigm of failure and progress (technological and political), opening it up to a set of reciprocal and non-linear insights. In this context, the use of Enzensberger texts also goes beyond any form of periodisation. By engaging a dialogue with his “Jeu de construction pour une théorie des medias” / Constituents of a Theory of the Media (1970), several essays gathered in Médiocrité et folie / Mediocrity and Madness (1988), as well as his recent autobiographical interview Erinnerungen an einen Tumult (2014), this text shows how criticism by the German writer, while constantly revitalised by the emergence of “new” objects (tabloid press, mobile video, television, Internet, smartphones), invites us to overcome any technological determinism to simultaneously consider the political potential of the first activist video groups and platforms dominating the Internet today.

Qu’est-ce qui nous soulève ? L’exposition présentée au Jeu de Paume par Didi-Huberman répond à cette question en cinq temps, formant les chapitres d’une histoire de la révolte racontée par les moyens d’une anthropologie politique des images. Comment se soulever, donc ? 1. Par éléments (déchaînés) – 2. Par gestes (intenses) – 3. Par mots (exclamés) – 4. Par conflits (embrasés) – 5. Par désirs (indestructibles). Finement orchestré et rassemblant des matériaux visuels aussi hétérogènes que singuliers, le dispositif met en place un vaste système d’échos où s’aventure le spectateur. Les éléments exposés ouvrent des brèches dans nos savoirs, se compliquent les uns les autres, se démentent et se répondent, parfois avec évidence, parfois plus confidentiellement. Des séries se créent au départ des objets exposés, sans doute différentes pour chacun, séries sur lesquelles viennent se greffer les trouvailles du commissaire au fur et à mesure du trajet dans l’exposition.

De nombreux observateurs ont décrit chez Twombly cette réconciliation picturale de l’adulte avec la vitalité ou la liberté enfantine, tout en marquant – bien entendu – la non-coïncidence de ses œuvres avec les productions des enfants. Malgré sa sensibilité aux compositions gauches, sales, « tripotées », « déjetées » de l’artiste américain, Roland Barthes voyait chez Twombly une « paresse » (et donc une « élégance extrême ») sans commune mesure avec le caractère appliqué (on tire la langue) et appuyé du dessin d’enfant. D’autres ont pu invoquer l’intention artistique, non manifeste ou moins construite chez l’enfant. Dans son texte sur « Le corps parlant de Cy Twombly » (cf. catalogue de l’exposition), Richard Leeman rappelle que l’artiste avait apporté une réponse à ce problème, indiquant que « sa ligne est enfantine (childlike), mais pas puérile (childish) ». Twombly disait encore à ce propos : « C’est très difficile à imiter : pour avoir cette qualité, il faut se projeter soi-même dans la ligne de l’enfant, cela doit se ressentir ». Dessiner comme un enfant de 5 ans, ce n’est pas à la portée de tout le monde. Un enfant de cinq ans pourrait le faire, oui, sans doute, il pourrait en tout cas profiter encore de cette liberté que Twombly a tellement bien su convertir, mais un adulte non-artiste ne le pourrait pas.

On the basis of Antonio Gramsci’s praxis philosophy, taken up by André Tosel, and Cornelius Castoriadis’ works on radical imaginary, this article analyses the debate about Marxism, during the year 1946, between two intellectual reviews: Les Temps Modernes and Critique. If the creation of those reviews is deeply related to a social context and an interdiscourse influenced by the political and ideological rise of extreme left – particularly the French Communist Party –, their project consists in a critical questioning of communist discourses, returning to Marx’s and Hegel’s texts. References to these philosophies induce different rhetorical and argumentative particularities that we intend to study in order to understand the complex relations between the rhetoric of a sociohistorical interdiscourse and his ideological substructure.
