Violences de l'énonciation, énonciations de la violence dans Faire semblant c'est mentir de Dominique Goblet
No full textÉchappant aux catégories traditionnelles de la bande dessinée, l’œuvre Faire semblant c’est mentir de Dominique Goblet interroge, en une chronologie éclatée répartie sur quatre chapitres, les relations entretenues par l’auteure avec différents membres de son entourage familial. On s’intéressera ici plus spécifiquement aux épisodes mettant en scène les diverses figures parentales (père, mère, belle-mère), en tant qu’ils thématisent une forme de violence plurielle. On tâchera notamment de montrer que cette violence s’articule autour de dispositifs énonciatifs spécifiques, qui font de la parole le lieu d’un affrontement permanent. Tout l’enjeu de cette étude sera ainsi d’interroger cette violence énonciative, ses modalités de représentation ainsi que le rôle qu’elle occupe dans l’entreprise autobiographique pour le moins singulière menée par l’auteure.
Abstract:
Escaping the traditionnal categories of comic books, Dominique Goblet's Faire semblant c'est mentir questions, in a fragmented chronology running through four chapters, the relationships between the author and her family. I will focus more specifically on the various episodes involving her parents (mother, father, stepmother), as they dramatize a pluralist violence. I will especially try to show that this violence is build on some very specific enunciative layouts, which turn the speech into a permanent conflict. Thus, my point will be to question this enunciative violence, its modalities of representation, and its function in the very particular autobiographical project of the author
Effect of dietary nitrate on respiratory physiology at high altitude - results from the Xtreme Alps study
No full textNitric oxide (NO) production plays a central role in conferring tolerance to hypoxia. Tibetan highlanders, successful high-altitude dwellers for millennia, have higher circulating nitrate and exhaled NO (ENO) levels than native lowlanders. Since nitrate itself can reduce the oxygen cost of exercise in normoxia it may confer additional benefits at high altitude. Xtreme Alps was a double-blinded randomised placebo-controlled trial to investigate how dietary nitrate supplementation affects physiological responses to hypoxia in 28 healthy adult volunteers resident at 4559m for 1 week; 14 receiving a beetroot-based high-nitrate supplement and 14 receiving a low-nitrate ‘placebo’ of matching appearance/taste. ENO, vital signs and acute mountain sickness (AMS) severity were recorded at sea level (SL) and daily at altitude. Moreover, standard spirometric values were recorded, and saliva and exhaled breath condensate (EBC) collected. There was no significant difference in resting cardiorespiratory variables, peripheral oxygen saturation or AMS score with nitrate supplementation at SL or altitude. Median ENO levels increased from 1.5/3.0mPa at SL, to 3.5/7.4mPa after 5 days at altitude (D5) in the low and high-nitrate groups, respectively (p=0.02). EBC nitrite also rose significantly with dietary nitrate (p=0.004), 1.7 to 5.1μM at SL and 1.6 to 6.3 μM at D5, and this rise appeared to be associated with increased levels of ENO. However no significant changes occurred to levels of EBC nitrate or nitrosation products (RXNO). Median salivary nitrite/nitrate concentrations increased from 56.5/786µM to 333/5,194µM at SL, to 85.6/641µM and 341/4,553µM on D5. Salivary RXNO rose markedly with treatment at SL from 0.55µM to 5.70µM. At D5 placebo salivary RXNO had increased to 1.90µM whilst treatment RXNO decreased to 3.26µM. There was no association with changes in any observation variables or AMS score. In conclusion, dietary nitrate supplementation is well tolerated at altitude and significantly increases pulmonary NO availability and both salivary and EBC NO metabolite concentrations. Surprisingly, this is not associated with changes in hemodynamics, oxygen saturation or AMS development
Development and application of BIO-SAFE
No full textBIO-SAFE is a policy and legislation based model for the assessment of impacts of flood prevention measures on biodiversity in river basins. Within the framework of IRMA-SPONGE, a transnational version of the model BIO-SAFE (Spreadsheet Application For Evaluation of BIOdiversity) for the rivers Rhine and Meuse was developed. The model was specifically designed for policy and legislation based impact assessment of flood risk reduction measures on biodiversity in floodplains. BIO-SAFE is an assessment model that quantifies the policy and legislation status of species in river basins for several taxonomic groups. The model uses data on presence of species and ecotopes. Results show that the BIO-SAFE method enables the user to express politically and legally based biodiversity values in quantitative terms and to compare biodiversity values for various taxonomic groups, landscape-ecological units (e.g. ecotopes) and physical planning scenarios. BIO-SAFE gives information regarding the degree to which floodplain designs, observed or predicted trends of floodplain developments or actual values meet goals set in (inter)national agreements. Assessments with BIO-SAFE, in an early stage of the planning process, of actual situations and different scenarios for an area can help direct the planning process in the stage where this is still possible. Because of its policy-based character, BIO-SAFE yields complementary information to more established ecological biodiversity indices and to singlespecies habitat models and ecological network analysis.Irma-Spong
