Le planisme à la CGT : Les origines d’une refonte syndicale au tournant du Front populaire
2008
National audience; Durant les années 30 le syndicalisme est, à l’image du mouvement ouvrier français, affaibli et divisé. Le planisme apparaît alors comme un courant de pensée neuf dans une offre politique figée depuis la création du parti communiste en 1920. Alors que le parti socialiste rejette toute révision doctrinale, la CGT va quant à elle se saisir de cette opportunité pour entamer une modification de sa stratégie qui renforcerait la politique de présence du syndicat. Mêlée à l’antifascisme à partir de 1934, cette difficile rénovation idéologique ne rencontrera que peu d’écho chez ses partenaires du monde politique mais explique cependant, et pour partie, la politique sociale du Fron…
Les socialistes et la CGT. Le tournant du Front populaire (1934-1939)
2006
National audience; Pour toute la période de l’entre-deux-guerres, les études sur le syndicalisme se sont principalement portées sur la question de son indépendance et en particulier sur le phénomène de « colonisation communiste ». Pourtant il serait tout à fait utopiste de croire que la SFIC ait été la seule des deux grandes formations politiques de la classe ouvrière à s’être intéressée à la question syndicale . Si depuis 1907, la SFIO reconnaît la nécessaire indépendance du syndicalisme, cette reconnaissance n’empêche pas nombre de socialistes de s’intéresser à l’organisation économique de la classe ouvrière. Durant le Front populaire, le Parti socialiste va d’ailleurs adopter une attitud…
Le syndicalisme précurseur de l’unité : politisation et recomposition interne
2008
National audience; Mouvement global, le Front populaire est donc à l’origine de mutations profondes pour la CGT. C’est à cette unité et à ses conséquences que nous nous intéresserons, en axant notre réflexion et nos questionnements autour de trois axes, celui du caractère précurseur de l’unité syndicale, de la politisation du mouvement syndical et de sa recomposition interne.
Perturbation vectors to evaluate air quality using lichens and bromeliads: a Brazilian case study.
2017
10 pages; International audience; Samples of one lichen species, Parmotrema crinitum, and one bromeliad species, Tillandsia usneoides, were collected in the state of Rio de Janeiro, Brazil, at four sites differently affected by anthropogenic pollution. The concentrations of aluminum, cadmium, copper, iron, lanthanum, lead, sulfur, titanium, zinc, and zirconium were determined by inductively coupled plasma-atomic emission spectroscopy. The environmental diagnosis was established by examining compositional changes via perturbation vectors, an underused family of methods designed to circumvent the problem of closure in any compositional dataset. The perturbation vectors between the reference s…
Assessing drugs of abuse distribution in Turia River based on geographic information system and liquid chromatography mass spectrometry
2017
Drugs of abuse are continuously discharged into wastewaters as part of their elimination process. Pollution at very low concentrations appears to be broad in environmental compartments near populated areas. A total of 42 drugs of abuse and metabolites were analysed in surface water samples collected in 2012 and 2013 by solid phase extraction and liquid chromatography coupled to mass spectrometry. Analytical results of target compounds were georeferenced and integrated into a geographical information systems (GIS). Ecotoxicological risk of drugs of abuse detected in the Turia River was evaluated in this study by calculating risk quotient (RQ). In 2012, 6 compounds were detected in a total of…
Evaluation of historical atmospheric pollution in an industrial area by dendrochemical approaches
2019
International audience; We conducted a dendrochemical study in order to evaluate the exposure of territories and 19 populations to different types of pollutants and to characterise the history of pollution in one of the 20 most intensely industrialised areas of Europe: the industrial port zone of Fos, also heavily 21 urbanised. 22 To perform the study, two tree species have been selected, Pinus halepensis and Populus nigra, on arural plot located roughly 20 km away from the industrial harbor, an urban plot located in the city of Fos-sur-Mer and an industrial plot. Our study indicated that poplar was a more relevant model forthe dendrochemical studies exhibiting a higher bioaccumulation capa…
13C/12C composition, a novel parameter to study the downward migration of paper sludge in soils
2002
δ13C values of crop and forest soils were measured 8 years after disposal of paper sewage sludge. The carbon transfer from paper sludge downward to the first humic layer is evidenced by a 13C-enrichnient of up to + 5.6‰ due to the input of 13C-enriched sludge carbonates. 13C/12C composition is thus a novel, sensitive parameter to follow the downward transfer of paper sludge carbon.
Establishment of Polycomb silencing requires a transient interaction between PC and ESC
2001
Two distinct types of Polycomb complexes have been identified in flies and in vertebrates, one containing ESC and one containing PC. Using LexA fusions, we show that PC and ESC can establish silencing of a reporter gene but that each requires the presence of the other. In early embryonic extracts, we find PC transiently associated with ESC in a complex that includes EZ, PHO, PH, GAGA, and RPD3 but not PSC. In older embryos, PC is found in a complex including PH, PSC, GAGA, and RPD3, whereas ESC is in a separate complex including EZ, PHO, and RPD3.
Exact Voronoi diagram of smooth convex pseudo-circles: General predicates, and implementation for ellipses
2013
International audience; We examine the problem of computing exactly the Voronoi diagram (via the dual Delaunay graph) of a set of, possibly intersecting, smooth convex \pc in the Euclidean plane, given in parametric form. Pseudo-circles are (convex) sites, every pair of which has at most two intersecting points. The Voronoi diagram is constructed incrementally. Our first contribution is to propose robust and efficient algorithms, under the exact computation paradigm, for all required predicates, thus generalizing earlier algorithms for non-intersecting ellipses. Second, we focus on \kcn, which is the hardest predicate, and express it by a simple sparse $5\times 5$ polynomial system, which a…
