Les pratiques occultes des contrôleurs de gestion:une étude ethnographique du «sale boulot»

(VF)À partir d’une étude ethnographique, nous analysons les pratiques occultées de contrôleurs de gestion. Nous montrons que,souhaitant s’identifier à des consultants internes, ils ne vont pas chercher à « se vendre » auprès des managers. Au contraire, ils adoptent une stratégie d’évitement, tentent de déléguer, ou de dissimuler, les tâches qu’ils considèrent comme impures et qui constituent leur sale boulot. Le rapport des contrôleurs à leur travail, leur choix d’orienter l’attention vers certains phénomènes plutôt que d’autres, influencent les pratiques de contrôle dans l’organisation.(VA)Based on an ethnographic study, this paper analyzes hidden activities in management controllers’ practice. We show that, while they wish to appear as business partners, they do not “sell” themselves to managers. On the contrary, they adopt avoidance strategies, intending to delegate or dissimulate the tasks they consider as impure, that is to say those that constitute their “dirty work”. We argue that management accountants’ feelings about their job shape control processes within the organisation.contrôleurs de gestion;ethnographie;sale boulot;management controllers;ethnography;dirty work.

L’écriture en chantier. Les projets dramaturgiques d’Henry Bauchau (1950-1970)

Cet article détaille tous les projets dramaturgiques, pour la plupart inaboutis, d’Henry Bauchau depuis 1951. L’auteur était sensible au théâtre social qui avait vu le jour dans l’entre-deux-guerres et qui mettait en scène des personnages historiques ou mythologiques. Rome d’or sera la première tentative ; toute une série d’autres suivront, dont Gengis Khan et plus tard La reine en amont ne seront que les parties émergées de l’iceberg. « Les premiers projets dramatiques d’Henry Bauchau sont extraordinairement riches. Investissant les figures héroïques qui s’imposent à lui, il interroge celles-ci dans les luttes qu’elles mènent, à commencer par celle, ontologique, qui les conduit à accepter et à aller au-delà de leur propre destin.

Le roman sentimental gay francophone

En 1997, les Éditions gaies et lesbiennes publient Embarquement pour l’amour, inaugurant la première collection de romans sentimentaux dans l’édition française. Plus qu’anecdotique, la revendication d’une littérature sentimentale gay implique deux enjeux. D’une part, ce type de production met en évidence la romance et se distancie du trait “sexuel”, qui continue à servir de point de repère à la définition de l’homosexualité. D’autre part, bien que genre populaire, le roman sentimental est légitimé dans la production éditoriale : il s’agit ainsi de déspécialiser la fiction dite “homosexuelle” afin de l’intégrer dans la littérature générale. Cette étude analyse l’émergence du roman sentimental gay dans l’édition française et montre que, loin de reproduire les structures stéréotypiques du roman sentimental hétérosexuel, le roman étudié déconstruit au contraire ces structures au profit d’un imaginaire du texte dans lequel les deux protagonistes masculins façonnent une relation basée sur l’équité des rôles dans le couple

Sol-gel preparation of pure and doped TiO₂ films for the photocatalytic oxidation of ethanol in air

Stable sols of TiO2 were synthesized by a non-aqueous sol-gel process using titanium (IV) isopropoxide as precursor. The microstructure, optical and morphological properties of the films obtained by spin-coating from the sol, and annealed at different temperatures, were investigated using scanning electron microscopy, transmission electron microscopy, diffuse reflectance spectroscopy and ellipsometry. The crystalline structure of the films was characterized by X-ray diffraction and their photocatalytic activity was evaluated for the oxidation of ethanol in air. The influence of the calcination temperature, pre-heat treatment and the number of layers was studied. Simultaneous thermo-gravimetric and differential thermal analysis measurements were carried out to ascertain the thermal decomposition behavior of the precursors. In order to obtain a higher photoresponse in the visible region, a series of vanadium-, niobium- and tantalum-doped TiO2 catalysts was synthesized by the same sol-gel method. For V doping two different precursors, a vanadium alkoxide and V2O5, were used. The effect on the crystallization and photocatalytic activity of the doped TiO2 films was investigated. Furthermore, to identify the effective composition of the samples, they were characterized by X-ray photoelectron spectroscopy and the surface area of the powders was measured by N-2 adsorption. The 10 wt.% doped catalysts exhibit high photocatalytic activity under visible light and among them the best performance was obtained for the sample containing Ta as dopant. The crystallite sizes are closely related to the photocatalytic activity

Coating process of honeycomb cordierite support with Ni/boehmite gels

This study presents the development of a method for the washcoating of Ni/boehmite gels, prepared by sol-gel process, onto the surface of a commercial ceramic monolith. Indeed, cordierite monolith in honeycomb shape was used as substrate for Ni/Al2O3 deposition. An experimental assembly was made in order to apply the coating on the cordierite surface. Different suspensions were used with various viscosities and multiple coating parameters were tested as the withdrawal speed, or the number of impregnations. It was observed that the simple deposition of the Ni/boehmite gel led to the formation of coating. Different morphologies were observed, and defects were highlights as cracks, coating-free areas or aggregates. Among the various studied parameters, the pH of the sol appeared to play a role even more important than the viscosity. Indeed, the sol acidified with nitric acid showed a coating which was almost free of cracks or of large aggregates. Moreover, the use of a mix of a slurry of calcined alumina particles and of colloidal boehmite appeared also as an interesting path. The beneficial influence of a slurry was attributed to a better resistance of the coating against the stresses induced during drying, and a deviation of the cracks in the gels by slurry grains

MβCD concurs with IL-4, IL-13 and IL-25 to induce alterations reminiscent of atopic dermatitis in reconstructed epidermis

Reconstructed human epidermis (RHE) mimic normal human in vivo epidermis in terms of histology, distribution of differentiation markers and barrier functionality. A typical transcriptional profile and the activation of signalling pathways reminiscent of atopic dermatitis (AD) lesional skin can be obtained in RHE upon incubation with methyl-β-cyclodextrin (MβCD), a molecule that extracts cholesterol from plasma membranes, thereby disrupting lipid microdomains. However, barrier function and morphology remain unaltered in those conditions, requiring further refinement of the model
