Doing Gender Online. Ordinary Practice Beyond Utopian Ideals

Does the Internet change or reproduce gender relations, understood as the norms and the practices that differentiate and hierarchize between women and men? How so? These questions are at the core of the current issue of RESET, dedicated to ways of “doing gender online”. The aim is to both question the gendered use of new technology and revisit the theoretical perspectives of gender studies through the lens of digital practices. This issue echoes the perspectives of a 2003 article by Josiane J..

Retour sur Le Savant et le Populaire

La fin des années 1970 a été une période très particulière pour la sociologie de la culture française. Je vais me permettre de raconter ces moments de façon personnelle. J’étais alors en thèse à l’EHESS sous la direction de Raymonde Moulin au sein du Centre européen de sociologie historique, laboratoire dirigé par Raymond Aron. Ma thèse portait sur l’œuvre photographique de Lewis Carroll, et j’étais, de ce fait, insérée dans le petit groupe de doctorants et chercheurs qui travaillaient, au se..

Numerical simulations with the P-Hydroslag model to predict phosphorus removal by steel slag filters

The first version of the P-Hydroslag model for numerical simulations of steel slag filters is presented. This model main original feature is the implementation of slag exhaustion behavior, crystal growth and crystal size effect on crystal solubility, and crystal accumulation effect on slag dissolution. The model includes four mineral phases: calcite, monetite, homogeneous hydroxyapatite (constant size and solubility) and heterogeneous hydroxyapatite (increasing size and decreasing solubility). In the proposed model, slag behavior is represented by CaO dissolution kinetic rate and exhaustion equations; while slag dissolution is limited by a diffusion rate through a crystal layer. An experimental test for measurement of exhaustion equations is provided. The model was calibrated with an experimental program made of three phases. Firstly, batch tests with 300 g slag sample in synthetic solutions were conducted for the determination of exhaustion equation. Secondly, a slag filter column test fed with synthetic solution was run for 623 days, divided into 9 cells and sampled at the end of the experiment. Finally, the column was dismantled, sampled and analyzed with XRD, TEM and SEM. Experimental column curves for pH, oPO4, Ca and inorganic carbon were well predicted by the model. Crystal sizes measured by XRD and TEM validated the hypothesis for homogeneous precipitation while SEM observations validated the thin crystal layer hypothesis. A preliminary validation of the model resulted in successful predictions of a steel slag filter longevity fed with real wastewater

Superconductivity in TTF[Ni(dmit)2]2 films

We report on the observation of a superconducting transition in a fiber-like film of the TTF[Ni(dmit)2]2 phase electrodeposited on silicon substrates. Superconductivity is evidenced by a broad drop of the resistance below 0.8K under the application of a hydrostatic pressure of 7.7 kbar. Zero resistance is not reached due to the contribution of inter-fiber resistance. Superconductivity is confirmed by the application of a magnetic field perpendicular to the plane of the film. The critical field determined on the film is in agreement with that obtained in bulk single crystals

Sociologie des médias

Sabine Chalvon-Demersay, directrice d’étudesDaniel Dayan, Dominique Pasquier, directeurs de recherche au CNRS Médias et activités Le séminaire a poursuivi l’exploration entamée au cours des années précédentes, à savoir les liens entre les travaux sur la fiction et ceux sur l’information, dans le cadre d’une sociologie qui ne se cantonne pas à la question des médias ou de la communication mais pose des questions générales en termes de sociologie des normes. Les séances de cette année ont porté..

Expression of Three Cell Adhesion Molecules in Bladder Carcinomas: Correlation with Pathological Features

Recently, independent studies have shown that the expression of two integrin chains, β4 and α2, plus the epithelial cadherin are related to tumour progression in human bladder carcinomas. For the first time, we compare the expression of these three cell adhesion molecules using immunohistochemical analysis of consecutive cryosections from a series of 50 bladder tumours. E‐cadherin, β4, and α2 were strongly expressed in normal urothelium. A majority of non‐invasive bladder cancers stained positively for E‐cadherin (62%), whereas only 29% expressed normal positivity for α2, and only 35% for β4. However, most invasive tumours presented an aberrant expression of α2 (81%), β4 (100%), and E‐cadherin (75%). We studied the correlation of immunoreactivity with histological grade and stage. The α2 pattern was not correlated with stage and grade. In contrast, loss of normal β4 expression was significantly related to increasing tumour grade and deep invasion with a higher correlation for grade. Finally, E‐cadherin expression was highly correlated with stage, but not with grade. Thus our results indicate that, although many invasive bladder tumours presented a disorder in expression of the two integrins α2 and β4, E‐cadherin appeared to be a better marker of invasiveness in bladder carcinomas
