« Ce qui vient au monde pour ne rien troubler ne mérite ni égards ni patience » : Mike Ward et l'industrie de l'humour au Québec, une analyse posturale

Dans l’opinion publique, Mike Ward a longtemps été perçu comme un humoriste provocateur, reconnu pour la vulgarité de son langage et ses propos. Avant l’année 2015, les chroniqueurs en particulier qualifient son humour de « facile » et lui font coller à la peau une image d’enfant terrible. Pourtant, à partir de cette année-là, un basculement s’opère. L’humoriste devient copropriétaire du premier comédie club francophone montréalais, le Bordel, et redevient animateur de Mike Ward Sous Écoute, qui sera le podcast francophone le plus écouté au monde. L’humoriste prend le contrôle de son image puisqu’il n’hésite pas à prendre position vis-à-vis des différents détenteurs de pouvoir de l’industrie. Cette recherche a pour objectif de comprendre comment ce rôle actif, au sein même de l’industrie, permet d’une part à Ward d’encourager un renouvellement et une diversification de l’offre. D’autre part, ces tribunes —en particulier le podcast—sont aussi pour lui l’occasion de renégocier et de remodeler son image publique. Les réponses fournies par l’analyse exhaustive de 277 podcasts, auxquels a participé Ward, nous ont permis de cibler des récurrences dans son discours et de brosser un portrait intéressant du métier d’humoriste, du public d’humour et des différentes instances reconnues dans le milieu (Juste pour rire, l’École nationale de l’humour, l’Association des professionnels de l’industrie de l’humour , mais aussi la critique). La conclusion nous permet de montrer qu’en somme, l’humoriste a initié une trajectoire singulière, qui lui a permis d’outrepasser son simple rôle d’humoriste pour devenir un élément constitutif de l’industrie, lui qui agit désormais à titre de régisseur de la norme supportant l’émergence des humoristes

Influence of Uranium on Bacterial Communities: A Comparison of Natural Uranium-Rich Soils with Controls

This study investigated the influence of uranium on the indigenous bacterial community structure in natural soils with high uranium content. Radioactive soil samples exhibiting 0.26% - 25.5% U in mass were analyzed and compared with nearby control soils containing trace uranium. EXAFS and XRD analyses of soils revealed the presence of U(VI) and uranium-phosphate mineral phases, identified as sabugalite and meta-autunite. A comparative analysis of bacterial community fingerprints using denaturing gradient gel electrophoresis (DGGE) revealed the presence of a complex population in both control and uranium-rich samples. However, bacterial communities inhabiting uraniferous soils exhibited specific fingerprints that were remarkably stable over time, in contrast to populations from nearby control samples. Representatives of Acidobacteria, Proteobacteria, and seven others phyla were detected in DGGE bands specific to uraniferous samples. In particular, sequences related to iron-reducing bacteria such as Geobacter and Geothrix were identified concomitantly with iron-oxidizing species such as Gallionella and Sideroxydans. All together, our results demonstrate that uranium exerts a permanent high pressure on soil bacterial communities and suggest the existence of a uranium redox cycle mediated by bacteria in the soil

Conservation value for birds of traditionally managed isolated trees in an agricultural landscape of Madagascar

Isolated trees have distinctive economic, social and cultural value for the Betsileo people living on the edge of the protected forest corridor between Ranomafana and Andringitra national parks, in South-East Madagascar. Many of these trees are Ficus spp., traditionally protected and respected. At the landscape level, they are isolated features in a heterogeneous mosaic, providing fruit, shade and aesthetic services in open cultivated areas. Within the current management system, isolated trees may also contribute significantly to the provision of ecological services by enhancing bird diversity in open areas outside the forest. We identified practices and values linked to isolated tree uses and management through ethnographic data collection. Bird presence and abundance were sampled by 338 point counts in isolated trees and open areas of the agricultural mosaic. Isolated trees were occupied by 18 out of 32 (56%) bird species in the agricultural mosaic, including 8 (25%) endemic forest species. Endemic forest birds were significantly more numerous in isolated trees than in open habitats, both in species richness and abundance (mean P value < 0.001). Overall bird species richness was significantly higher in open areas containing isolated trees, than in areas without isolated trees. Bird species richness in Ficus spp. was significantly higher than in other isolated tree species, although no differences were detected in abundance or within guilds. Community-based management of isolated trees may thus represent an opportunity for convergence between bird conservation goals outside protected areas and local management values and practices

Fast and accurate identification and antibiotic resistance profiling of micro-organisms in blood cultures by SWATH-MS proteomics

International audienceToday, approximately 1.3 million people die each year worldwide from bacterial antimicrobial resistance (AMR). AMR is of great concern in the context of bloodstream infections (BSIs) when it evolves into sepsis. If MALDI-TOF has markedly shortened the delay of the pathogen identification step, AMR evaluation is still based on growth tests in the presence of antibiotics. The latter, negatively impacts the diagnosis turnaround time, thus the administration to the patient of active antimicrobial agents. With the aim of streamlining this turnaround time to less than an hour from a positive blood culture, the LC/SWATH-MS sensitivity and specificity performances were evaluated to concomitantly provide the identity and antibiotic resistance profile of pathogens related to BSIs based on peptide surrogates
