Album papier, album numérisé : une dialectique outil-objet avec le TBI
No full textInternational audienceRéférence : Bastide Isabelle, Fluckiger Cédric, (2016), Album papier, album numérisé: une dialectique objet-outil avec le TBI, in Villemonteix F., Baron G.-L., Béziat J. (dirs), L'école primaire et les technologies informatisées. Des enseignants face aux TICE, Villeneuve D'Ascq, Presses Universitaires du Septentrion, p. 47-58. Introduction Cette communication vise à présenter les premiers résultats d'une recherche exploratoire sur les usages du tableau blanc interactif (TBI) en primaire. Nous cherchons à étudier, d'un point de vue didactique, l'utilisation de TBI lors de lectures partagées d'albums de littérature de jeunesse en classe de CP. Cette communication s'inscrit dans le cadre des premiers travaux d'une recherche menée par l'équipe Théodile-CIREL (Lille 3), commanditée par l'Inspection de Lille et financée sur réserve parlementaire du Sénat, visant à identifier, décrire et caractériser les ressources didactiques et pédagogiques utilisées par les enseignants, en particulier lorsqu'ils sont confrontés à l'usage d'un TBI. La question que nous posons plus spécifiquement dans cette communication est celle des modifications et adaptations que peuvent subir les ressources au sein de la classe durant différentes séances, en fonction des possibilités interactives offertes par le TBI. Nous prenons le cas du travail d'une enseignante en classe CP, qui utilise, en lieu et place d'une méthode de lecture traditionnelle, des albums dans leur version papier ainsi que leur version numérisée. Nous confrontons l'analyse des séances observées d'une part à celle de l'entretien effectué avec l'enseignante et d'autre part à l'analyse du contenu des albums dans leurs deux versions. TBI, ressources didactiques et lectures d'album : cadres théoriques Les recherches sur les technologies numériques éducatives posent de manière fréquente la question de l'instrumentation des apprentissages, des genèses instrumentales (Rabardel, 1995) à l'oeuvre ; les discours, activités instrumentées peuvent être étudiés dans différentes perspectives. Le TBI a par exemple été interrogé dans sa relation au travail enseignant (Numa Bocage et al., 2011). En revanche, une perspective didactique visant à mettre en relation les usages d'outils numériques pour l'élève ou l'enseignant avec les contenus d'enseignement et d'apprentissages est plus rarement mise en oeuvre (Fluckiger, 2012). Il nous semble pourtant que la diffusion de certaines technologies modifie singulièrement l'organisation des contenus, leur appréhension, perception, appropriation par les différents acteurs. C'est ce point de vue qu

Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
[Newspaper Clipping: Author Claims Evidence of Second JFK Assassin #1]
No full textNewspaper article titled "Author Claims Evidence of Second JFK Assassin." The article states that author Richard J. Whalen concluded "that there is circumstantial evidence to support the theory of a second assassin in the shooting of President John F. Kennedy.
Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
John F. Kennedy telegram to Roosevelt
No full textJersey Homesteads (later the Borough of Roosevelt) was established in the 1930s as an agro-industrial cooperative community. It was established specifically for urban Jewish garment workers, many of whom had emigrated from Europe. President John F. Kennedy sent a telegram to the citizens of Roosevelt, New Jersey, apologizing for not being able to attend the memorial dedication in honor of former President Franklin Delano Roosevelt. (Jersey Homesteads became Roosevelt in 1945 in honor of the president.) President Kennedy expressed his gratitude to the people of Roosevelt for constructing the memorial, and commented that it will serve as a constant reminder of Roosevelt's good works
Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either
