Comme d'autres institutions académiques européennes, les universités suisses connaissent des changements importants et « l'excellence académique » est devenu un critère central lors de la sélection des dossiers pour les postes de rang professoral. Dans cet article, nous analyserons les critères d'excellence tels qu'ils apparaissent dans le programme Professeur.e.s boursiers.ières du FNS et les confronterons aux résultats d'une recherche sur les trajectoires de la relève académique que nous avons menée à l'Université de Lausanne. Nous montrerons comment la définition de l'excellence académique obéit à des logiques genrées qui rendent l'accession à un poste professoral plus difficile pour les femmes que pour les hommes. Nous verrons pourquoi les critères d'évaluation des sciences dures, qui sont peu à peu transférés vers les sciences humaines, renforcent les mécanismes d'exclusions des femmes des mondes académiques.

Some recent studies have characterized the stability of blood variables commonly measured for the Athlete Biological Passport. The aim of this study was to characterize the impact of different shipments conditions and the quality of the results returned by the haematological analyzer. Twenty-two healthy male subjects provided five EDTA tubes each. Four shipment conditions (24, 36, 48, 72 h) under refrigerated conditions were tested and compared to a set of samples left in the laboratory also under refrigerated conditions (group control). All measurements were conducted using two Sysmex XT-2000i analyzers. Haemoglobin concentration, reticulocytes percentage, and OFF-score numerical data were the same for samples analyzed just after collection and after a shipment under refrigerated conditions up to 72 h. Detailed information reported especially by the differential (DIFF) channel scatterplot of the Sysmex XT-2000i indicated that there were signs of blood deterioration, but were not of relevance for the variables used in the Athlete Biological Passport. As long as the cold chain is guaranteed, the time delay between the collection and the analyses of blood variables can be extended. Copyright© 2015 John Wiley & Sons, Ltd.
