Controls of knowledge production, sharing and use in bureaucratized Professional Service Firms
One of the main obstacles to the current bureaucratization trend in large professional service firms (PSFs) is the organic nature of professional knowledge production, sharing and use. Centralized knowledge management (KM) systems aimed at codifying âbest practiceâ solutions to recurrent client questions for large-scale reuse are a common strategy increasingly employed to overcome this obstacle. Using a socio-ethnographic case study of a business law firm in Paris, this research examines whether the use of centralized KM systems in bureaucratized PSFs contributes to a shift in power from professionals to managers. More specifically, are administrative controls over knowledge resources increasing, or do professionals retain power (i.e. some level of social and self-control) over knowledge production, sharing and use? The results of this study indicate that, far from losing ground, professionalsâ social and self-controls have been reinvented and reformed in a bureaucratized context

Texturation de YBaCuO par la méthode de l'échangeur thermique
The Heat Exchanger Method (HEM) has been used to prepare bulk textured YBaCuO ceramics. The experimental process and the thermal parameters used for texturing are described. The resulting bulk textured ceramics have been investigated by X-ray diffraction, optical and scanning electronic microscopies. A 92 K temperature transition and a of 5â000 A/cm at 77 K in the absence of magnetic field have been shown by ac susceptibility measurements.Un dispositif de croissance cristalline basĂ© sur la technique de l'Ă©changeur thermique a Ă©tĂ© dĂ©veloppĂ© au laboratoire. Cette mĂ©thode a Ă©tĂ© appliquĂ©e Ă l'obtention de cĂ©ramiques orientĂ©es de YBaCuO. Les conditions expĂ©rimentales ainsi que les diffĂ©rents paramĂštres thermiques affĂ©rents Ă la mĂ©thode de texturation utilisĂ©e sont prĂ©cisĂ©s. La texturation des Ă©chantillons obtenus a Ă©tĂ© caractĂ©risĂ©e par diffraction des rayons X, par microscopie optique et par microscopie Ă©lectronique Ă balayage ; la susceptibilitĂ© alternative a rĂ©vĂ©lĂ© une transition supraconductrice Ă 92 K et une densitĂ© de courant critique de 5â000 A/cm Ă 77 K et sans champ magnĂ©tique
Partial phase diagram of the ternary reciprocal system KF-AlF3-Al2O3-K2O
International audienceA K2ZrF6 treatment improves the wettability of SiC (or C) fibers by aluminum alloys. A possible mechanism involves the formation of K3AlF6 followed by the dissolution of the alumina film. DTA analyses of K3AlF6-α-Al2O3 mixtures show that a temperature invariant transition occurs at 1132K, the solid containing trace amounts of KAlF4 and ÎČ-alumina at room temperature. Part of the ternary reciprocal system KF-AlF3-Al2O3-K2O is calculated, the Gibbs free energy of the liquid being described according to the CIS theory. The K3AlF6-Al2O3 isopteth section is given. It is characterized by a liquidus with a deep minimum at 1132K and 11.6 wt % alumina
