Monsieur le Minotaure et son point de vue

Les visions hallucinées de Friedrich Dürrenmatt, l'un des plus importants écrivains suisses de l'après-guerre, au travers des dessins et des manuscrits consacrés aux mythes de la Pythie, du Minotaure et de Midas. L'itinéraire créatif de Friedrich Dürrenmatt, outre sa production littéraire bien connue, est constellé d'une intense activité de peintre, de dessinateur et de graveur sur cuivre, activité qui délimite un important terrain de confrontation des pensées et des thèmes caractérisant sa recherche. Ce volume, qui accompagne l'exposition organisée par le célèbre architecte tessinois Mario Botta, présente une sélection de dessins et de notes de voyage appartenant à la collection privée de Charlotte Kerr-Dürrenmatt. Ceux-ci ont trait aux mythes de la Pythie, du Minotaure et de Midas, auxquels Dürrenmatt a consacré tant de réflexions. Les thèmes de la mythologie grecque ont toujours été présents dans la recherche de l'auteur sur la condition humaine, au point qu'il en est parfois arrivé à se représenter, de manière autobiographique, comme le protagoniste des événements décrits. Ces oeuvres revêtent une importance fondamentale car elles mettent en valeur l'importance et la signification que l'écrivain attribue à cette activité, considérée comme " mineure " par la critique mais qu'il faut en revanche interpréter comme un complément important des métaphores écrites auxquelles renvoie toute sa pensée.

Endocardite infectieuse: mise au point [Infective endocarditis: update]

The pathogenesis of infective endocarditis (IE) is being dissected at the molecular level, which should help redefine new preventive and therapeutic strategies against IE. In spite of improving health care, the incidence of IE has not decreased over the last decades. While classical predisposing conditions such as rheumatic heart disease were being eradicated, new features of IE have emerged. These include IE in intravenous drug users, IE in elderly patients with sclerotic valve disease, prosthetic valve IE and nosocomial IE. The epidemiology, pathogenesis, diagnosis, prevention and treatment of IE are being reviewed in this article.

Victimització en joves de protecció a la infància i l’adolescència i de justícia juvenil

A Catalunya, un nombre significatiu d’infants i adolescents es troba sota la guarda i tutela del sistema de protecció i d’altres són atesos pel sistema de justícia juvenil. En molts casos, aquests joves han viscut experiències de maltractaments i abusos per part de les principals figures cuidadores, però també d’altres formes de violència en contextos diversos que poden incloure: el carrer, l’escola, el grup d’iguals, les noves tecnologies o els propis centres on poden residir provisionalment. Aquesta multiplicitat d’experiències de violència els converteix amb el que es coneix com a polivíctimes. Però entre l'experiència de victimització en la infància i el desenvolupament de problemes psicològics podem trobar la resiliència, la capacitat de l’ésser humà per superar o recuperar-se amb èxit de circumstàncies adverses. I aquí és on els professionals poden intervenir amb èxit. Els objectius principals d’aquest estudi són conèixer la prevalença d’experiències de victimització en aquests joves, identificar els casos de polivictimització, analitzar les característiques sociodemogràfiques, victimològiques i el nivell de desajust psicològic que presenten. Alhora, identificar perfils de resiliència i analitzar el seu efecte en el nivell de malestar psicològic del jove víctima. Els resultats ens indiquen que són els recursos personals, relatius a la confiança en un mateix, la fe en un futur millor, la capacitat d’identificació i connexió amb les pròpies emocions o les habilitats socials, els que permeten al jove fer front a les dificultats amb èxit. Aquests recursos personals són els que marcaran la diferència en la posterior reintegració social i correcte desenvolupament del jove i, per tant, els professionals els han de conèixer, enfortir i desenvolupar.

Diagnostics VIH tardifs en 2009 en Suisse: motivation a un dépistage systématique du VIH [Late diagnoses of HIV infection in 2009 in Switzerland: towards a universal HIV testing?]

Individuals who are unaware of their HIV infection constitute a fragile and a critical population both from a personal and from a community-based point of view: if the infection is diagnosed too late, the outcome can be complicated by AIDS-defining diseases, whose prognosis may remain unfavourable even after the initiation of a potent antiretroviral therapy. These patients contribute to the virus spreading into the community, owing to a high viral load. It is now necessary to recognise the limits of a risk behaviour and disease-driven HIV screening policy. Since 2006, the American guidelines recommend a routine HIV testing for all patients age 13 to 64 years unless they specifically refuse the test (opt-out). In Switzerland, the recommendations remain so far risk-centred.

Rockfall monitoring by Terrestrial Laser Scanning ¿ case study of the basaltic rock face at Castellfollit de la Roca (Catalonia, Spain)

This case study deals with a rock face monitoring in urban areas using a Terrestrial Laser Scanner. The pilot study area is an almost vertical, fifty meter high cliff, on top of which the village of Castellfollit de la Roca is located. Rockfall activity is currently causing a retreat of the rock face, which may endanger the houses located at its edge. TLS datasets consist of high density 3-D point clouds acquired from five stations, nine times in a time span of 22 months (from March 2006 to January 2008). The change detection, i.e. rockfalls, was performed through a sequential comparison of datasets. Two types of mass movement were detected in the monitoring period: (a) detachment of single basaltic columns, with magnitudes below 1.5 m3 and (b) detachment of groups of columns, with magnitudes of 1.5 to 150 m3. Furthermore, the historical record revealed (c) the occurrence of slab failures with magnitudes higher than 150 m3. Displacements of a likely slab failure were measured, suggesting an apparent stationary stage. Even failures are clearly episodic, our results, together with the study of the historical record, enabled us to estimate a mean detachment of material from 46 to 91.5 m3 year¿1. The application of TLS considerably improved our understanding of rockfall phenomena in the study area.

Cinema and the Work of Doré

According to Ray Harryhausen, a special effects expert in the film industry, "Gustave Doré would have made a great director of photography . . . He saw things from the point of view of the camera." Doré's work has had a permanent impact on the imaginative realm of film since its very early days. In return, the silver screen has etched Doré into the 20th century imagination. Almost every film about the Bible since The Life and Passion of Jesus Christ produced by Pathé in 1902 refers to his illustrations, and every film adaptation of Dante or Don Quixote has used him as a model, from Georg Wilhelm Pabst and Orson Welles to Terry Gilliam. All films dealing with life in London in the Victorian era by directors ranging from David Lean, to Roman Polanski and Tim Burton draw on the visions in London: a pilgrimage for their sets. A large number of dream fantastical or phantasmagorical scenes take their inspiration from Doré's graphic world, beginning with Georges Méliès' A Trip to the Moon in 1902. In the realm of cartoons and animation, Walt Disney owes a huge debt to Doré. Doré primal forests, from Atala in particular, were also used in the various versions of King Kong from 1933 to the 2005 film by Peter Jackson, who had already drawn on Doré for The Lord of the Rings. Jean Cocteau was also indebted to the illustrations for Perrault's Fairy Tales for his Beauty and the Beast (1945), as was George Lucas for the character Chewbacca in Star Wars (1977) and even the Harry Potter film series. Through his influence on film history, Doré shaped the mass culture imagination.

Impact of phenotype definition on genome-wide association signals: empirical evaluation in human immunodeficiency virus type 1 infection.

Discussion on improving the power of genome-wide association studies to identify candidate variants and genes is generally centered on issues of maximizing sample size; less attention is given to the role of phenotype definition and ascertainment. The authors used genome-wide data from patients infected with human immunodeficiency virus type 1 (HIV-1) to assess whether differences in type of population (622 seroconverters vs. 636 seroprevalent subjects) or the number of measurements available for defining the phenotype resulted in differences in the effect sizes of associations between single nucleotide polymorphisms and the phenotype, HIV-1 viral load at set point. The effect estimate for the top 100 single nucleotide polymorphisms was 0.092 (95% confidence interval: 0.074, 0.110) log(10) viral load (log(10) copies of HIV-1 per mL of blood) greater in seroconverters than in seroprevalent subjects. The difference was even larger when the authors focused on chromosome 6 variants (0.153 log(10) viral load) or on variants that achieved genome-wide significance (0.232 log(10) viral load). The estimates of the genetic effects tended to be slightly larger when more viral load measurements were available, particularly among seroconverters and for variants that achieved genome-wide significance. Differences in phenotype definition and ascertainment may affect the estimated magnitude of genetic effects and should be considered in optimizing power for discovering new associations.
