Interroger l'objet, c'est aussi, au-delà de sa forme ou de son sens, interroger le temps — notre rapport à l'origine, au passé ou au devenir. Nulle part cependant, cette question ne se pose de façon plus cruciale que dans l'acte de conserver ou restaurer l'objet d'art : car l’intervention le situe dans un champ de valeurs parfois hétéroclites. C’est au travers de l’axiologie que prennent corps des pratiques conservatives ou restauratives différenciées. Le praticien devient par conséquent, au sens propre, un « enseignant » : il donne sens aux signes, il éduque notre regard à l'objet préservé dans son authenticité et nous apprend à l’écouter respectueusement.

L'ambition de cet ouvrage est de proposer une esthétique de la forme " mosaïque " à travers les temps et à travers les arts. Dans le sillage du livre de Lucien Dällenbach, Mosaïques (Seuil, 2001), à qui le livre est dédié, les divers auteurs discutent, chacun pour une discipline différente, l'importance et l'impact de ce que l'on considère souvent comme la figure de base de l'esthétique contemporaine : la mosaïque. Plus particulièrement, ils examinent le statut d'une forme tiraillée entre l'homogénéité idéale de l'œuvre considérée comme un ensemble et la singularité des fragments qui la constituent. Croisant les arts et les disciplines, multipliant les exemples venus de traditions extrêmement diverses, les études rassemblées dans ce livre offrent la synthèse d'un champ de recherches bariolé et surprenant. Passant de l'action painting à la poésie, des nanonobjets numérisés aux écrans-mosaïques, de la musique sérielle au film peint ou encore du roman au cédérom, L'œuvre en morceaux examine des oeuvres et des démarches aussi diverses que celles de Stéphane Mallarmé, Stan Brakhage, Chris Marker, James Joyce, Jackson Pollock, Gertrude Stein, Edgard Varèse, etc. [less ▲]

Tantôt fondées sur le mode critique et ironique, tantôt basées sur le principe du musée imaginaire ou du cabinet de curiosités, les oeuvres-collection génèrent une multitude de réflexions. Elles peuvent aussi bien naître d'une remise en cause du dispositif muséal et des logiques de promotion de l'art que d'une fascination pour ce monde secret et merveilleux qu'est la collection [...] [less ▲]

In today’s globalized India, not only has the outsourcing sector generated employment for some two million people, but it has also promoted the mesmerizing idea of a ‘new India’ of foreign investment, global markets, economic growth and expanding middle class. Drawing its workforce from an urban, college-educated Indian youth who receive training in ‘accent neutralization,’ the call centre industry offers the hope of rapid upward mobility, even if this involves working grinding shifts and faking an American name, accent, location, and time-zone. As against the somewhat cultish belief that ‘pretend-Nancy’ or ‘pretend-Bill’ (Susan Sontag) can reap the benefits of the corporate search for cut-rate labor, critics such as Harish Trivedi and Siddhartha Deb have proved highly critical of the ways in which the call centre industry results in creating a generation of ‘cyber-coolies’ and cultural emulators. A “public spectacle,” in Shehzad Nadeem’s words, outsourcing can be seen to promote an Indian fantasy landscape of high tech, virtual lives, and consumer culture that is reproduced and/or resisted in a growing number of cultural productions. Investigating TV series (Outsourced, Mumbai Calling), blockbusters (Slumdog Millionaire, The Best Exotic Marigold Hotel), and documentaries (John and Jane Toll-Free, Bombay Calling), this paper will explore the cosmos of call centres from a cross-cultural perspective.

Only 5 Of?p stars have been identified in the Galaxy. Of these, 3 have been studied in detail, and within the past 5 years magnetic fields have been detected in each of them. The observed magnetic and spectral characteristics are indicative of organised magnetic fields, likely of fossil origin, confining their supersonic stellar winds into dense, structured magnetospheres. The systematic detection of magnetic fields in these stars strongly suggests that the Of?p stars represent a general class of magnetic O-type stars. [less ▲]

Daily changes in the concentrations of carbon and nitrogen species were monitored during the course of a Lagrangian drifter experiment in a recurrent upwelling filament south of Cape Finisterre (NW Iberian Upwelling System). A drifting buoy released at the southern edge of the upwelling centre generated by the Cape moved 60km southwestwards from 3 to 7 August 1998. Organic matter in the 50m deep study water mass (average 77±2 μM C) consisted of: 57μM C of dissolved organic matter (DOM) with a C/N molar ratio of 19±2; 6μM C of DOM with a C/N ratio of 9±2, and 14μM C of 50% DOM and 50% suspended organic matter (POMsusp) with a C/N ratio of 6.0±0.4. Net conversion of consumed inorganic salts into accumulated TOM=POMsusp+DOM was 40% for nitrogen and 30% for carbon. Since the parcel of water crossed the shelf-edge, these conversion efficiencies are equivalent to net horizontal export-ratio of 0.4 and 0.3 respectively. A second drifter was deployed in the offshore-end of the filament, and was displaced 20km west between 14 and 17 August 1998. Nitrate was exhausted in the surface water and no significant changes were observed in the variables measured during the course of the second experiment. Low C/N ratios (6.5±0.4) and rapid POMsusp/DOM inter-conversion in the 20 μM C excess observed in the study volume points to the persistence of the labile materials formed on the shelf during transport to the ocean. Our data demonstrate a) the key role of upwelling filaments in off-shelf export of organic materials and b) the major contribution of DOM to this horizontal export, a previously unaccounted amount.

Sleep is thought to participate in the consolidation of recent memory traces. We tested this hypothesis in humans by using functional neuroimaging (functional magnetic resonance imaging and positron emission tomography). First, following the training procedural visuo-motor learning task (pursuit task), total sleep deprivation on the first post-training night significantly deteriorates the gain in performance, which is usually observed after one complete night of sleep. In parallel, sleep deprivation hampers the changes in functional segregation and connectivity, which underpin the gain in performance usually observed in subjects allowed to sleep on the first post-training night. Second, following the training on an implicit memory task (probabilistic serial reaction time task), some brain areas are reactivated during rapid eye movement (REM) sleep on the first post-training night. The reactivation was shown to be related to the processing of high-level material and to be modulated by the amount of learning achieved during the training session. These changes in activity do not involve isolated brain areas but entire macroscopic cortico-subcortical networks. Taken together, the results suggest an off-line processing of recent memory traces during sleep. [less ▲]

L’histoire de l'office de la Trinité a déjà fait couler beaucoup d’encre. Les philologues se sont intéressés à la place du formulaire dans l’histoire des offices versifiés du haut moyen âge, aux sources d’inspiration des textes, au principe et à la stratégie d’inspiration ; les musicologues au mode de composition musicale comme au rapport entre les textes chantés et la musique.

Much remains to be discovered about the fate of recent memories in the human brain. Several studies have reported the reactivation of learning-related cerebral activity during post-training sleep, suggesting that sleep plays a role in the offline processing and consolidation of memory. However, little is known about how new information is maintained and processed during post-training wakefulness before sleep, while the brain is actively engaged in other cognitive activities. We show, using functional magnetic resonance imaging, that brain activity elicited during a new learning episode modulates brain responses to an unrelated cognitive task, during the waking period following the end of training. This post-training activity evolves in learning-related cerebral structures, in which functional connections with other brain regions are gradually established or reinforced. It also correlates with behavioral performance. These processes follow a different time course for hippocampus-dependent and hippocampus-independent memories. Our experimental approach allowed the characterization of the offline evolution of the cerebral correlates of recent memories, without the confounding effect of concurrent practice of the learned material. Results indicate that the human brain has already extensively processed recent memories during the first hours of post-training wakefulness, even when simultaneously coping with unrelated cognitive demands.

To further characterize perceptual memory consolidation during sleep, we used a coarse orientation discrimination task in which participants had to discriminate the orientation of orthogonal gratings occluded by increasing levels of noise. In a first study (N = 11), we showed that the learning effect in this task is retinotopic (position-specific) and orientation specific. In a second experiment, we assessed the effect of nocturnal sleep, as opposed to the effect of time, on perceptual learning. A first group of participants was trained in the morning, tested in the evening and retested the next morning (morning-evening-morning, MEM, N = 11); a second group was trained in the evening, tested the next morning, and retested in the evening (evening-morning-evening; EME; N = 12). Between training and testing, EME subjects improved significantly more (after a night of sleep) than MEM subjects (after 12 waking hours). Similarly, between test and retest, performance of MEM subjects (after a full night of sleep) improved significantly more than in EME subjects (after 12 further waking hours). These results suggest a beneficial effect of sleep on coarse orientation discrimination. Further studies are needed to characterize the neural correlates of this perceptual learning and the offline consolidation of perceptual memory. [less ▲]
