Das Werk als Feige und als Figur. Ambivalenzen der Rezeption zwischen Valéry, Mallarmé, "Tel Quel" und Francis Ponge

L’œuvre poétique de Valéry est caractérisée par une esthétique de la perfection, de la pureté et de la clôture. La série ouverte et hétérogène des "Cahiers", en revanche, ne se laisse guère ranger dans la catégorie de l’œuvre. Selon Valéry, la réorientation intellectuelle à la base de cette opposition est due au "choc" subi par la découverte de l’œuvre mallarméenne. Les divers écrits valéryens sur Mallarmé nous servent à reconstruire cette relation ambivalente et nous aident à éclairer sa conception non moins ambivalente de l’œuvre d’art. Nous soutenons que ce ne sont pas ses propres travaux, mais les poésies de Mallarmé qui lui semblaient des œuvres achevées à proprement parler. Pour décrire l’expérience de perfection et d’achèvement que lui fournit la lecture du "Coup de dés", Valéry se sert de la notion de figure qui, entre autres, comporte des associations géométriques. Sous la forme d’un hommage ambivalent, Francis Ponge oppose aux concepts valéryens de figure et d’œuvre d’art une poétique de l’objet matériel et concret qui s’incarne dans "La figue (sèche)", publiée en 1960 comme pièce inaugurale de la revue "Tel Quel".

Do Instructional Videos on Sputum Submission Result in Increased Tuberculosis Case Detection? A Randomized Controlled Trial.

OBJECTIVE We examined the effect of an instructional video about the production of diagnostic sputum on case detection of tuberculosis (TB), and evaluated the acceptance of the video. TRIAL DESIGN Randomized controlled trial. METHODS We prepared a culturally adapted instructional video for sputum submission. We analyzed 200 presumptive TB cases coughing for more than two weeks who attended the outpatient department of the governmental Municipal Hospital in Mwananyamala (Dar es Salaam, Tanzania). They were randomly assigned to either receive instructions on sputum submission using the video before submission (intervention group, n = 100) or standard of care (control group, n = 100). Sputum samples were examined for volume, quality and presence of acid-fast bacilli by experienced laboratory technicians blinded to study groups. RESULTS Median age was 39.1 years (interquartile range 37.0-50.0); 94 (47%) were females, 106 (53%) were males, and 49 (24.5%) were HIV-infected. We found that the instructional video intervention was associated with detection of a higher proportion of microscopically confirmed cases (56%, 95% confidence interval [95% CI] 45.7-65.9%, sputum smear positive patients in the intervention group versus 23%, 95% CI 15.2-32.5%, in the control group, p <0.0001), an increase in volume of specimen defined as a volume ≥3ml (78%, 95% CI 68.6-85.7%, versus 45%, 95% CI 35.0-55.3%, p <0.0001), and specimens less likely to be salivary (14%, 95% CI 7.9-22.4%, versus 39%, 95% CI 29.4-49.3%, p = 0.0001). Older age, but not the HIV status or sex, modified the effectiveness of the intervention by improving it positively. When asked how well the video instructions were understood, the majority of patients in the intervention group reported to have understood the video instructions well (97%). Most of the patients thought the video would be useful in the cultural setting of Tanzania (92%). CONCLUSIONS Sputum submission instructional videos increased the yield of tuberculosis cases through better quality of sputum samples. If confirmed in larger studies, instructional videos may have a substantial effect on the case yield using sputum microscopy and also molecular tests. This low-cost strategy should be considered as part of the efforts to control TB in resource-limited settings. TRIAL REGISTRATION Pan African Clinical Trials Registry PACTR201504001098231.
