Oedipe civilisateur menacé

À partir de ma pratique clinique, je constate que le fonctionnement psychique de certains enfants et adolescents s’est modifié dans notre civilisation, sous l’influence de changements survenus dans la structure familiale, d’une dissolution de nos instances surmoïques collectives, du refus de reconnaître l’inéluctabilité de la perte dans tout destin humain, et sous l’impact de facteurs technologiques tels qu’Internet. Ces changements soumettent le psychisme infantile à une activité de déliaison et/ou l’amènent à privilégier ce mode de fonctionnement par rapport à l’activité de liaison. Dans ces situations, la structure oedipenne, même si elle est toujours présente, ne parvient plus à jouer son rôle organisateur essentiel du psychisme humain car pour se déployer, elle a besoin d’un environnement pare – excitant et porteur de limites cohérentes dans les registres pulsionnels et narcissiques. Diverses « dérives » apparaissent, en particulier les mouvements d’indifférenciation sociétaux éloignent de l’investissement de la conflictualité intrapsychique et tendent vers un appauvrissement de l’imaginaire et une « déliaison » visant à tout réduire à un sexuel brut. Ceci est grave, difficilement réversible, et a des conséquences sur le travail du psychanalyste et sur sa place dans la société

The Politics of Experience: Robert Morris, Minimalism, and the 1960s

Robert Morris\u27s oeuvre, unlike the work of most other so-called minimalist artists, is both stylistically and intellectually diverse. His range was broad: expressionist paintings, Duchamp-inspired objects, dances and performances, minimalist sculptures, large scale installations and sound environments, earth and land reclamation works, films and videos, and political acts against the museum, the labor economy, and the Vietnam war. The philosophical sources for Morris\u27s art (he was a philosophy major at Reed College in the late-1950s) are equally rich: Herbert Marcuse, Maurice Merleau-Ponty, Michel Foucault, Jean Piaget, Ludwig Wittgenstein, and Charles Sanders Peirce. As choreographer, writer of influential theoretical texts, and fine artist, Morris sharply questioned the pretensions of modernist art and culture. Extending the discourse of art history, this dissertation exposes the complex relationship between Morris\u27s work and the social and intellectual setting of the 1960s–a radical moment that witnessed a range of protest and dissent, from sexual liberation to the Vietnam war. Morris\u27s archive and writings, most of which have never before been examined, reveal his close relationship to many of these causes, political ambitions ignored by a formalist art history and criticism committed to aesthetic purity and the social removal of high art. Established readings of the minimalist movement center on more classical modernist sources such as the readymades of Duchamp, the phenomenological theories of Merleau-Ponty, and the formalist art of the Russian constructivists. At least for Morris, however, Marcuse\u27s call for the artist to reject modernism\u27s repressive demands for stylistic unity served as an important means for liberating the artist from the limited institutional boundaries of the gallery and the museum. Functioning within the contexts of performance halls, advertising campaigns, land reclamation sites, and even the streets of New York City, Morris appealed to artists and their patrons to broaden the audience for advanced art. Extending from his earliest works of the late 1950s to his mature art of the mid-1970s, the dissertation represents a test case for understanding the avant-garde\u27s intense questioning of the role of the artist and of art during a period of unprecedented social and cultural change

The finite tiling problem is undecidable in the hyperbolic plane

In this paper, we consider the finite tiling problem which was proved undecidable in the Euclidean plane by Jarkko Kari in 1994. Here, we prove that the same problem for the hyperbolic plane is also undecidable

About the domino problem in the hyperbolic plane, a new solution: complement

In this paper, we complete the construction of paper arXiv:cs.CG/0701096v2. Together with the proof contained in arXiv:cs.CG/0701096v2, this paper definitely proves that the general problem of tiling the hyperbolic plane with {\it \`a la} Wang tiles is undecidable.Comment: 20 page

Empirical Removal of Tides and Inverse Barometer Effect on DInSAR From Double DInSAR and a Regional Climate Model

Ice shelves-the floating extensions of the Antarctic ice sheet-regulate the Antarctic contribution to sea-level rise by restraining the grounded ice flowing from upstream. Therefore, ice-shelf change (e.g., ice-shelf thinning) results in accelerated ice discharge into the ocean, which has a direct effect on sea level. Studying ice-shelf velocity allows the monitoring of the ice shelves' stability and evolution. Differential synthetic aperture radar interferometry (DInSAR) is a common technique from which highly accurate velocity maps can be inferred at high resolution. Because ice shelves are afloat, small sea-level changes-i.e., ocean tides and varying atmospheric pressure (aka inverse barometer effect) lead to vertical displacements. If not accounted for in the interferometric process, these effects will induce a strong bias in the horizontal velocity estimation. In this article, we present an empirical DInSAR correction technique from geophysical models and double DInSAR, with a study on its variance propagation. The method is developed to be used at large coverage on short timescales, essential for the near-continuous monitoring of rapidly changing areas on polar ice sheets. We used Sentinel-1 SAR acquisitions in interferometric wide and extra -wide swath modes. The vertical interferometric bias is estimated using a regional climate model (MAR) and a tide model (CATS2008). The study area is located on the Roi Baudouin Ice Shelf in Dronning Maud Land, East Antarctica. Results show a major decrease (67 m·a -1 ) in the vertical-induced displacement bias.Fil: Glaude, Quentin. Université Libre de Bruxelles; Bélgica. Université de Liège; BélgicaFil: Amory, Charles.

Echocardiographic Changes and Long-Term Clinical Outcomes in Pediatric Patients With Pulmonary Arterial Hypertension Treated With Bosentan for 72 Weeks:A Post-hoc Analysis From the FUTURE 3 Study

FormUlation of bosenTan in pUlmonary arterial hypeRtEnsion (FUTURE) 3 was a 24-week open-label, prospective, and randomized phase 3 study that assessed the pharmacokinetics of bosentan 2 mg/kg b.i.d. or t.i.d. in children with pulmonary arterial hypertension (PAH). We report findings from a post-hoc analysis that explored the prognostic value of echocardiographic changes during FUTURE 3 in relation to clinical outcomes observed during the 24-week core study and 48-week extension. Patients aged ≥3 months to <12 years (n = 64) received oral doses of bosentan 2 mg/kg b.i.d. or t.i.d. (1:1) for 24 weeks, after which they were eligible to enter the extension with continued bosentan administration. Echocardiographic evaluations were performed at baseline, Week 12, and 24 of the core study via central reading, and analyzed post-hoc for correlation with clinical outcomes (time to PAH worsening, time to death, and vital status). Sixty-four patients were randomized in the core study [median (IQR) age 3.8 (1.7–7.8) years]; and 58 patients (90.6%) entered the 48-week extension. Most of the patients (68.8%) were receiving ≥1 PAH medication at baseline. Echocardiographic changes during the core study were small but with high variability. There were statistically significant associations at Week 24 between worsening of the parameters, systolic left ventricular eccentricity index (LVEIS) and E/A ratio mitral valve flow, and the outcomes of time to death and time to PAH worsening. Additional studies that utilize simple and reproducible echocardiographic assessments are needed to confirm these findings and subsequently identify potential treatment goals in pediatric PAH

Transport properties of ybco thin films near the critical state with no applied field

Transport measurements carried out on twinned ybco films are compared to the predictions of a previously proposed model suggesting that the vortices move along the films twin boundaries that behave as rows of Josephson weak links [P.Bernstein and J.F.Hamet, J.Appl.Phys.95 (2004) 2569]. The obtained results suggest that, except if the films are very thin, the twin boundaries consist of superimposed rows of weak links with mean height,ds, whose mean length along the TBs is an universal function of T/Tc, the reduced temperature. This conclusion yields a general expression for the critical surface current density of the films as a function of T/Tc and of the number of superimposed weak links rows, while the critical current density depends on ds. A comparison of the measurements reported by various authors shows that the nature of the substrate and the growth technique have both a strong effect on ds . The existence of superimposed weak links rows is attributed to extended defects generated by y2o3 inclusions.Comment: 33 pages, 13 figures; accepted for publication in Physica
