Mathieu Messager, Roland Barthes
No full textDans ce bref ouvrage des plus stimulants, Mathieu Messager – chercheur en langue et littérature française– donne à voir l’itinéraire intellectuel d’une figure centrale de la pensée française du vingtième siècle. Auteur singulier ayant fait œuvre d’écrivain tenté par la perspective d’un grand roman, Roland Barthes a traversé son époque de part en part, transcendant les modes, les courants et les tendances (du marxisme au structuralisme en passant par l’aventure sémiologique qu’il a contribué à..

Seulement, pour Roland Barthes, le problème du jaloux, ce n’est pas tant qu’il soit agressif, ni qu’il soit fou, ni qu’il soit exclu, mais qu’il soit comme tout le monde !Dans ce troisième épisode, Les Chemins de la philosophie reçoivent Mathieu Messager, maître de conférences en langues et littérature à l’université de Nantes, créateur du site Roland-Barthes.org
Le dernier fidèle de l'écriture (France Culture, La compagnie des auteurs, 12/06/2019)
No full textPassage à la radio dans le cadre de "La Compagnie des auteurs""Mathieu Messager, que nous retrouvons en seconde partie d'émission, est maître de conférences en langue et littérature française à l'Université de Nantes. Il est l'auteur de Roland Barthes, qui paraît dans la collection "Que sais-je ?" en juin 2019. Nous continuons d'approfondir avec lui la richesse de l'oeuvre de Barthes : ses articles sur le théâtre publiés dans de nombreuses revues, ses Essais critiques, mais surtout son travail de sémiologue. On peut définir la sémiologie, d'après Saussure, comme l'étude des signes dans la vie sociale : ainsi, Barthes publie dans la revue Communications de nombreux articles sur l'astrologie, la mode, la publicité, les recettes de cuisine... que les lecteurs retrouveront dans Mythologies, ouvrage paru en 1957 et par lequel Barthes aspire à un rêve de scientificité.
Global and local estimates of environmental flow requirements to sustain river ecosystems are poorly correlated
No full textData repository for ‘Global and local estimates of environmental flow requirements to sustain river ecosystems are poorly correlated ‘
prepared by Mathis L. Messager ([email protected])
1. Overview and background ----------------------------------------------------------
This documentation describes the input and output data associated with the analysis presented in: Messager, M. L., Dickens, W. S. C., Eriyagama, N., Tharme, R. E., Stassen, R. (2024). Limited comparability of global and local estimates of
environmental flow requirements to sustain river ecosystems. https://doi.org/10.1088/1748-9326/ad1cb5.
Environmental flows (e-flows) are a central element of sustainable water resource management to mitigate the detrimental impacts of hydrological alteration on freshwater ecosystems and their benefits to people. Many nations strive to protect e-flows through policy, and thousands of local-scale e-flows assessments have been conducted globally, leveraging data and knowledge to quantify how much water must be provided to river ecosystems, and when, to keep them healthy. However, e-flows assessments and implementation are geographically uneven and cover a small fraction of rivers worldwide. This hinders globally consistent target-setting, monitoring and evaluation for international agreements to curb water scarcity and biodiversity loss. Therefore, dozens of models have been developed over the past two decades to estimate the e-flows requirements of rivers seamlessly across basins and administrative boundaries at a global scale.There has been little effort, however, to benchmark these models against locally derived e-flows estimates, which may limit confidence in the relevance of global estimates. The aim of this study was to assess whether current global methods reflect e-flows estimates used on the ground, by comparing global and local estimates for 1194 sites across 25 countries. We found that while global approaches broadly approximate the bulk volume of water that should be precautionarily provided to sustain aquatic ecosystems at the scale of large basins or countries, they explain a remarkably negligible 0%–1% of the global variability in locally derived estimates of the percentage of river flow that must be protected at a given site. Even when comparing assessments for individual countries, thus controlling for differences in local assessment methods among jurisdictions, global e-flows estimates only marginally compared (R2 ⩽ 0.31) to local estimates. Such a disconnect between global and local assessments of e-flows requirements limits the credibility of global estimates and associated targets for water use. To accelerate the global implementation of e-flows requires further concerted effort to compile and draw from the thousands of existing local e-flows assessments worldwide for developing a new generation of global models and bridging the gap from local to global scales..
The data repository includes data required to perform this analysis as well as the data outputs from this analysis. Input data from local e-flow assessments included herein were either provided by collaborators or extracted from published governmental and academic reports by the authors. Input hydrographic data not available for download elsewhere were provided by Dr. Bernhard Lehner and hydrological simulations from PCR-GLOBWB 2.0 at a spatial resolution of 5 arc-min (not provided herein) were provided by Dr. ir. Edwin H. Sutanudjaja.
All scripts necessary to reproduce this analysis are freely available for all purposes (and can be copied, modified and distributed) at: https://github.com/messamat/globalEF_testPy (for data-preformatting and global e-flow calculations) and https://github.com/messamat/globalEF_testR (for comparing global and local MAF and e-flow estimates). The structure of the analysis relies as much as possible on good enough practices in scientific computing, which users are encouraged to read.

Roland Barthes
No full textInternational audienceFigure centrale de la pensée française, Roland Barthes (1915-1980) a traversé tous les grands courants intellectuels du XXe siècle. Il en fut même, selon ses dires, la chambre d’échos. Tour à tour « marxiste », « sémiologue » et « structuraliste », il fut surtout un auteur singulier, qui fit œuvre d’écrivain. Quarante ans après sa mort, on ne cesse de s’y reporter : il appartient à la catégorie restreinte de ceux que Foucault désigne comme des « fondateurs de discursivité », ces écrivains qui donnent à écrire et à penser.Mathieu Messager livre aux lecteurs d’aujourd’hui un portrait revisité de Roland Barthes, où il aborde directement ses travaux, dans leur contexte et dans leur chronologie, en mettant l’accent sur ce qui nous les rend si nécessaires et si actuels
