The ability to transfer learning to new situations lies at the heart of lifelong learning and the employability of university graduates. Because students are often unaware of the importance of learning transfer and staff do not always explicitly articulate this expectation, this article explores the idea that metacognition (intentional awareness and the use of that awareness) might enhance the development of learning transfer. Our exploratory study includes results from a survey of 74 staff and 118 students from five institutions in Australia, Belgium, UK, and USA. Our data indicate that many staff and a majority of students do not have a clear understanding of what learning transfer entails, and that there are many mismatches between staff and student perceptions, attitudes, and behaviors regarding learning transfer. This helps explain why learning transfer does not occur as often as it could. We found significant positive correlations between thinking about transfer and thinking about learning processes and the likelihood to use awareness of metacognition to guide practice. Our findings suggest a positive relationship between metacognition and learning transfer. Implications for scholarship of teaching and learning are discussed. [less ▲]

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.

Background: Cortical spreading depression (CSD) is the likely culprit of the migraine aura. Migraine is sexually dimorphic and thought to be a ‘‘low 5-HT’’ condition. We sought to decipher the interrelation between serotonin, ovarian hormones and cortical excitability in a model of migraine aura. Methods: Occipital KCl-induced CSDs were recorded for one hour at parieto-occipital and frontal levels in adult male (n 1⁄4 16) and female rats (n 1⁄4 64) one hour after intraperitoneal (i.p.) injection of 5-hydroxytryptophan (5-HTP) or NaCl. Sixty-five oophorectomized females were treated with estradiol- (E2) or cholesterol- (Chol) filled capsules. Two weeks later we recorded CSDs after 5-HTP/NaCl injections before or 20 hours after capsule removal. Results: 5-HTP had no effect in males, but decreased CSD frequency in cycling females, significantly so during estrus, at parieto-occipital (􏰀3.5CSD/h, p<0.001) and frontal levels (􏰀2.5CSD/h, p1⁄40.014). In oophorectomized rats, CSD susceptibility increased during E2 treatment at both recording sites (þ5CSD/h, p1⁄40.001 and þ3CSD/h, p<0.01), but decreased promptly after E2 withdrawal (􏰀4.7CSD/h, p < 0.001 and 􏰀1.7CSD/h, p 1⁄4 0.094). The CSD inhibitory effect of 5-HTP was significant only in E2-treated rats (􏰀3.4CSD/h, p 1⁄4 0.006 and 􏰀1.8CSD/h, p 1⁄4 0.029). Neither the estrous cycle phase, nor E2 or 5-HTP treatments significantly modified CSD propagation velocity. Conclusion: 5-HTP decreases CSD occurrence in the presence of ovarian hormones, suggesting its potential efficacy in migraine with aura prophylaxis in females. Elevated E2 levels increase CSD susceptibility, while estrogen withdrawal decreases CSD. In a translational perspective, these findings may explain why migraine auras can appear during pregnancy and why menstrual-related migraine attacks are rarely associated with an aura. [less ▲]

La cigarette électronique, aussi appelée e-cigarette, est présentée comme une alternative au tabagisme qui serait moins nocive pour la santé. Son fonctionnement repose sur la conversion d’un liquide en vapeur, sous l’action de la chaleur générée par un filament présent dans un atomiseur. Le liquide est majoritairement composé de propylène glycol et/ou de glycérine, utilisé(s) pour produire l’effet de fumée, auxquels s’ajoutent des arômes et, éventuellement, de la nicotine. A l’exception de cette dernière, potentiellement létale lorsqu’elle est ingérée à haute dose, ces constituants sont généralement reconnus comme sans danger. Cependant, les conséquences d’une inhalation chronique de propylène glycol sont méconnues. Avantageusement, les composés qui rendent la cigarette traditionnelle particulièrement nuisible – nitrosamines, formaldéhyde, métaux, monoxyde de carbone,… - sont soit absents, soit présents en faible quantité dans la vapeur d’une e-cigarette, sans comparaison avec les taux mesurés dans la fumée d’une cigarette conventionnelle. Il en résulte un profil de toxicité rassurant pour la e-cigarette, bien que son efficacité dans le sevrage tabagique reste à démontrer. [less ▲]
