Convergences/divergences : le dialogue intermédial dans Vues et visions de Claude Cahun

Ce mémoire étudie les rapports texte/image dans Vues et visions de Claude Cahun, première œuvre composite créée en collaboration avec la peintre graphiste Marcel Moore. L’objet littéraire protéiforme, appartenant au genre de l’iconotexte (Alain Montandon), instaure un dialogue intermédial entre le textuel et le visuel au point de déconstruire l’horizon d’attente du lecteur : celui-ci est incité à lire et à voir alternativement les poèmes en prose ainsi que les dessins de sorte que les frontières qui définissent l’espace du littéral et du figural apparaissent poreuses. Subdivisé en deux chapitres, notre travail s’attachera dans un premier temps à mettre en lumière le rôle de l’écriture qui intègre certains dessins de Moore. En nous inspirant de l’iconolecture (Emmanuelle Pelard), nous tenterons d’effectuer des liens entre la plasticité et la signification littérale des signes linguistiques qu’illustrent ces images-textes tout en étudiant les correspondances thématiques et formelles qu’elles entretiennent avec les poèmes de Cahun. Le second chapitre étudiera la manière dont le figural investit le texte littéraire en adoptant une approche intermédiale. Après avoir abordé la figure du double, une partie de l’analyse sera consacrée à la figure de l’allusion, une stratégie d’écriture pour introduire le visuel au sein du textuel, ce qui nous permettra d’entrer en matière pour étudier « l’image-en-texte » (Liliane Louvel). Enfin, l’effet-tableau ainsi que l’anamorphose seront employés comme cadre d’analyse afin de penser le dialogue qui se noue entre le pictural et le texte littéraire dans Vues et visions.

Variability of the Atlantic thermohaline circulation described by three-dimensional empirical orthogonal functions

We describe the use of bivariate 3d empirical orthogonal functions (EOFs) in characterising low frequency variability of the Atlantic thermohaline circulation (THC) in the Hadley Centre global climate model, HadCM3. We find that the leading two modes are well correlated with an index of the meridional overturning circulation (MOC) on decadal timescales, with the leading mode alone accounting for 54% of the decadal variance. Episodes of coherent oscillations in the sub-space of the leading EOFs are identified; these episodes are of great interest for the predictability of the THC, and could indicate the existence of different regimes of natural variability. The mechanism identified for the multi-decadal variability is an internal ocean mode, dominated by changes in convection in the Nordic Seas, which lead the changes in the MOC by a few years. Variations in salinity transports from the Arctic and from the North Atlantic are the main feedbacks which control the oscillation. This mode has a weak feedback onto the atmosphere and hence a surface climatic influence. Interestingly, some of these climate impacts lead the changes in the overturning. There are also similarities to observed multi-decadal climate variability.

Crystal structures of Λ-[Ru(phen)2dppz]2+ with oligonucleotides containing TA/TA and AT/AT steps show two intercalation modes

The ruthenium complex [Ru(phen)2(dppz)] (where phen is a phenanthroline and dppz a dipyridyl–phenazine ligand) is known as a ‘light switch’ complex because its luminescence in solution is significantly enhanced in the presence of DNA. This property is poised to serve in diagnostic and therapeutic applications, but its binding mode with DNA needs to be elucidated further. Here, we describe the crystal structures of the L enantiomer bound to two oligonucleotide duplexes. The dppz ligand intercalates symmetrically and perpendicularly from the minor groove of the d(CCGGTACCGG)2 duplex at the central TA/TA step, but not at the central AT/AT step of d(CCGGATCCGG)2. In both structures, however, a second ruthenium complex links the duplexes through the combination of a shallower angled intercalation into the C1C2/G9G10 step at the end of the duplex, and semi-intercalation into the G3G4 step of an adjacent duplex. The TA/TA specificity of the perpendicular intercalation arises from the packing of phenanthroline ligands against the adenosine residue.

Developmental changes in the balance of disparity, blur and looming/proximity cues to drive ocular alignment and focus

Accurate co-ordination of accommodation and convergence is necessary to view near objects and develop fine motor co-ordination. We used a remote haploscopic videorefraction paradigm to measure longitudinal changes in simultaneous ocular accommodation and vergence to targets at different depths, and to all combinations of blur, binocular disparity, and change-in-size (“proximity”) cues. Infants were followed longitudinally and compared to older children and young adults, with the prediction that sensitivity to different cues would change during development. Mean infant responses to the most naturalistic condition were similar to those of adults from 6-7 weeks (accommodation) and 8-9 weeks (vergence). Proximity cues influenced responses most in infants less than 14 weeks of age, but sensitivity declined thereafter. Between 12-28 weeks of age infants were equally responsive to all three cues, while in older children and adults manipulation of disparity resulted in the greatest changes in response. Despite rapid development of visual acuity (thus increasing availability of blur cues), responses to blur were stable throughout development. Our results suggest that during much of infancy, vergence and accommodation responses are not dependent on the development of specific depth cues, but make use of any cues available to drive appropriate changes in response.

Dose response relationship of droplet applications for the leaf-specific weed control in vegetable crops

As a prelude to leaf-specific weed control using droplets targeted by a robotic weeder, amounts of herbicide required to control individual weed seedlings were estimated. Roundup Biactive was applied at doses equivalent to 1/128th to four times the recommended rate in addition to undiluted Roundup and water controls. Based on the mean ground cover of the seedlings, the recommended dose (1.5 l ha 1) was estimated and droplets were applied to individual plants by micropipette. All treatments contained 1% AS 500 SL, Agromix (adjuvant). Three weeks after application dry weights (DW) of each seedling was recorded. DW reductions of 50% were achieved in the five species tested at less than the recommended rate whereas only in one species was a 90% reduction obtained at that rate. In Galium aparine for example, 19.3 μg of glyphosate reduced DW per plant by 90% compared to the recommended dose of 8.4 μg.

Nothing is safe: intolerance of uncertainty is associated with compromised fear extinction learning

Extinction-resistant fear is considered to be a central feature of pathological anxiety. Here we sought to determine if individual differences in Intolerance of Uncertainty (IU), a potential risk factor for anxiety disorders, underlies compromised fear extinction. We tested this hypothesis by recording electrodermal activity in 38 healthy participants during fear acquisition and extinction. We assessed the temporality of fear extinction, by examining early and late extinction learning. During early extinction, low IU was associated with larger skin conductance responses to learned threat vs. safety cues, whereas high IU was associated with skin conductance responding to both threat and safety cues, but no cue discrimination. During late extinction, low IU showed no difference in skin conductance between learned threat and safety cues, whilst high IU predicted continued fear expression to learned threat, indexed by larger skin conductance to threat vs. safety cues. These findings suggest a critical role of uncertainty-based mechanisms in the maintenance of learned fear.

Incorrigible and undisciplined lines in visual social research : ways of ‘writing’ and ‘drawing’ at the interstices

In this paper the author traces the possibilities afforded by engaging with the aesthetic, historic and socio-political nature of shodo (Japanese calligraphy) as an intersectional space. Shodo literally translated as 'the way of writing' is an artistic practice bringing together ink, brush and paper. It is simultaneously a juncture between studied discipline and an ongoing mediation of subjectivities. The calligrapher/writer/drawer communicates to the reader through the bold or subtle brush strokes, the pressure and movement at the completion of each stroke. The calligrapher/writer/drawer draws across the boundaries of text and image to meet the reader blurring the lines between subject and object. This discussion re-examines the hierarchical binaries of writing/drawing, text/image, self/Other as they play out from vanishing lines of distinction between truth and conjecture. Crossing these binaries opens up opportunity for decentring and questioning representational practice by enabling other possible meanings and practices to emerge (Lather, 2007). I work from a stance of theoretical promiscuity in order to disrupt constitutive discourses and restore the liminal in social research. Drawing across the fragments of research projects I illustrate the generative and speculative space of visualising pedascapes in educational research.

Reading ancient coins: automatically identifying denarii using obverse legend seeded retrieval

The aim of this paper is to automatically identify a Roman Imperial denarius from a single query photograph of its obverse and reverse. Such functionality has the potential to contribute greatly to various national schemes which encourage laymen to report their finds to local museums. Our work introduces a series of novelties: (i) this is the first paper which describes a method for extracting the legend of an ancient coin from a photograph; (ii) we are also the first to suggest the idea and propose a method for identifying a coin using a series of carefully engineered retrievals, each harnessed for further information using visual or meta-data processing; (iii) we show how in addition to a unique standard reference number for a query coin, the proposed system can be used to extract salient coin information (issuing authority, obverse and reverse descriptions, mint date) and retrieve images of other coins of the same type.

A linguagem do blog escolar em um trabalho com multiletramentos: compartilhando sentidos

This research, part of Applied Linguistics field, aims to analyze the language of a school blog, developed with the participation of students, as a work based on the conception of multiliteracies, focusing on the construction of different meanings. The research is carried on from the building and maintenance of a school blog, the Ieceblog, with students of Ensino Fundamental II, since 2008, in a private school in Natal-RN. The investigation of the language produced on a school blog is justified due to the interactive conceptions of writing and reading on the virtual environment. Given the fact that new technologies are a reality in the schools opened to the practices of multiliteracies, it is assumed that text, image, video, audio, non-graphic signs and hypertext intensifies the produced interaction, in which the students become real authors. In this perspective, some voices belonging to the statements that are formed through the posts and comments chosen to the analyses and reflection on the blog space as locus of productions of senses inserted in the school and the world environment, as well as for the identification of the language resources used to intensify the senses that emerge from it. From the view of dialogism conceptualized by Bakhtin Circle, the qualitative interpretive-research deepens the experience of a school blog focusing on digital language in line with the vision of digital literacy. From the blog posts, a corpus that promote the exposure of different manifestations of language in the design of digital multiliteracies is elected. Thereby, the method used was the dialogical analysis of speech based on Bakhtin s studies and the Circle. The corpus was taken from the blog s posts in order to point up the different language manifestations in the following categories: (i) mood reinforced by the mockery, (ii) search for compliance with school sphere, (iii) conflicting social values and consistent complicity between sense and verbal imagery, and finally (iv) social practices that take place from and through the discursive genre. The study points to the tension between the active voices in several directions, revealing the distorted unit of posts which, under the analytical observation raises multiple meanings in a responsive manner. The analysis of the dialogue interaction in which intersperses the digital one becomes more apparent that the multiliteracies events that are mediated by language in addition to structure of the language and makes us rethink the students

Flores carnais: Mapplethorpe e a natureza socio-política da pornografia

O artista norte-americado Robert Mapplethorpe se notabilizou pela plasticidade de seus portraits em preto e branco, mas também pelo escândalo de suas composições, nas quais corpos nus, sobretudo masculinos podiam ser vistos em atos homoeróticos e sadomasoquistas. Considerada como uma arte erótica por uns e como pornografia por outros, o fotógrafo acendeu o antigo debate pornografia versus erotismo. Considerando que tanto uns quanto outros termos, só adquirem seu sentido estético, social e político se pensados contextual e historicamente. Tomamos as fotografias de flores deste autor, para levar a cabo este debate, dialogando, para tanto, com as contribuições de Michel Foucault pelas leituras da sexualidade enquanto dispositivo. Valemo-nos, ainda dos conceitos de ars erotica e scientia sexualis tratado pelo mesmo autor, para estruturar nossas hipóteses, nas quais as flores do fotógrafo são deslocadas do terreno relativamente seguro do erotismo para serem lidas como armas de um terrorismo textual (e visual), aquele que Barthes viu como capaz de 'interveir socialmente, não fraças à sua popularidade ou seu sucesso, mas graças à 'violência que permite que o texto exceda as leis que a uma sociedade, uma ideologia, ou uma filosofia tomam para construir sua própria 'inteligibilidade histórica'''.
