This conceptual paper aims to respond to the poorly addressed question of the emergence of hybrid organizations – i.e. organizations that embrace several institutional logics. It does so by developing a model and a set of propositions focusing on the heterogeneity of the entrepreneurial team as a possible driver for hybridity throughout the entrepreneurial process and up to the emergence of a hybrid organization. As contributions to the literatures on (collective) entrepreneurship, imprinting and hybrid organizations, we advance several avenues and conditions under which the heterogeneity of the entrepreneurial team may imprint the entrepreneurial process and lead to the creation of hybrid organizations. Our propositions connect the individual, team and organizational levels and thus advance our understanding of how institutional logics can be combined across different levels of analysis and throughout the stages of an entrepreneurial process.

Dans la documentation papyrologique relative aux pratiques médicales de l’Égypte gréco-romaine et byzantine, le genre des listes de produits pharmaceutiques n’a encore jamais fait l’objet, ni d’un inventaire, ni d’une étude exhaustifs. Dans le cadre de nos recherches doctorales sur la typologie des papyrus documentaires grecs et latins à caractère médical, c’est cette lacune que l’on se propose de combler, d’une part en cataloguant, au moyen de la fiche Mertens-Pack³ du CEDOPAL, la trentaine de listes de produits pharmaceutiques provenant d’Égypte, écrites en grec sur papyrus et ostracon (IIIe s. av. J.-Chr.-VIIe s. apr. J.-Chr.), auxquelles on ajoutera deux listes latines sur tablettes de bois, provenant du camp romain de Vindolanda (c. 100p), et, d’autre part, en analysant les aspects formels, paléographiques, textuels et contextuels de ces documents médicaux qui peuvent correspondre, soit à un inventaire de droguiste, soit à une commande, soit à une ou plusieurs recettes dont l’état fragmentaire du support a fait disparaître les proportions. On comparera les données obtenues avec d’autres pièces papyrologiques, spécialement les nombreuses prescriptions médicales, ainsi que les comptes, les reçus de paiement ou encore les lettres privées relatives à des demandes de médicaments ou à la livraison de substances pharmaceutiques.

Spectral observations made with the long slit of the Space Telescope Imaging Spectrograph (STIS) on board Hubble have been used to construct spectral maps of the FUV Jovian aurora. They reveal that the amount of absorption by overlying methane shows significant spatial variations. In this report, we examine the relationship between the auroral brightness of the unabsorbed H2 emission that is proportional to the precipitated electron energy flux, and the ultraviolet color ratio, a proxy of the mean electron energy. We find that it varies significantly between the different components of the aurora and in the polar region. Although no global dependence can be found, we show that the two quantities are better organized in some auroral components such as regions of the main aurororal emission. By contrast, the dependence of the electron characteristic energy in high-latitude and diffuse aurora regions on the auroral energy input is generally more scattered. We conclude that the various auroral components are associated with different electron acceleration processes, some of which are not governed by a simple relation linking the value of a field-aligned acceleration potential with the parallel currents flowing from the ionosphere.

We present in this paper a new generic approach to variable branching in branch-and-bound for mixed- integer linear problems. Our approach consists in imitating the decisions taken by a good branching strategy, namely strong branching, with a fast approximation. This approximated function is created by a machine learning technique from a set of observed branching decisions taken by strong branching. The philosophy of the approach is similar to reliability branching. However, our approach can catch more complex aspects of observed previous branchings in order to take a branching decision. The experiments performed on randomly generated and MIPLIB problems show promising results. [less ▲]

The constantly increasing requests for the measurement of serum 25-hydroxyvitamin D over the last years has led reagent manufacturers to market different automated and semi-automated methods, that being unfortunately not fully harmonized, yield different results. Liquid chromatography coupled to tandem mass spectrometry (LC/MS2) has more recently been introduced. This approach allows the distinction between the two forms of 25-hydroxyvitamin D and to measure other metabolites. This approach also requires harmonization to curtail the differences between the different analytical methods. To meet this requirement, the American National Institutes of Health (NIH), the CDC (Centre for Disease Control and Prevention) in Atlanta, the NIST (National Institute of Standards and Technology) and the vitamin D Reference laboratory of Ghent University have pooled their expertise to develop a standardization program. This article reviews the main elements and the difficulties of the automated and semi-automated methods for 25-hydroxyvitamin D, from sample preparation to the analytical phase, as well as those related to mass spectrometry. It also addresses the issues related to the clinical decision thresholds and the possibility of measurements in different biological liquids. [less ▲]
