L’image, sous ses divers aspects, a joué un rôle essentiel dans la vie des anciens Grecs, en particulier dans le domaine religieux, puisque elle était l’une des modalités de perception du divin. En Grèce, la figuration anthropomorphe des dieux est largement majoritaire. Toutefois, en se tournant vers un support particulier, le vase peint, et un type de représentation particulier, la statue divine, on montrera ici que l’anthropomorphisme a pu amener une certaine ambiguïté. Dans la céramique, les représentations de statues fonctionnent sur plusieurs modes, selon la chronologie. C’est ce que l’on propose d’analyser, en examinant un groupe de vases décorés d’un thème semblable et sur lesquels une divinité est représentée, mais soit sous la forme d’une figure « vivante », soit d’une statue plus ou moins bien caractérisée. Cette étude permettra d’aborder les concepts de « fixité » et de « mouvement » de/dans l’image, mais aussi d’explorer quelques pistes de réflexions sur l’image divine et, plus largement, sur les modes de représentation du divin en Grèce ancienne.

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.

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 ▲]

L’aménagement transsexuel comme solution à l’adolescence La transsexualité est souvent banalisée par les médias, séduits par l’idée facile à vendre d’une âme sexuée, donc du drame de la possible inadéquation entre le sexe psychique et le sexe corporel. L’observation clinique rigoureuse de son élaboration plaide cependant pour une architecture complexe, résultant d’une dynamique subtile entre le psychisme, l’histoire et l’environnement. En effet, dans l’analyse d’un cas clinique, nous constatons que, face au risque de l’effondrement identitaire d’une structure fragile le Moi tente de se renforcer par l’organisation de mécanismes de défense qui élabore une nouvelle identité étayée sur un physique transité vers l’autre sexe. Si l’on analyse les interactions précoces sous l’angle de la formation de l’identité sexuelle, le noyau « genré » du Moi peut subir une double attaque, par manque d’identification au même et par attaque mortifère du différent. Le Moi se trouve ainsi délié et persécuté par des objets partiels ou peu introjectés. A l’adolescence, moment potentiellement traumatique de la sexuation, le jeune se trouve confronté à l’interrogation sur son identité sexuelle, et lorsque le noyau « genré » s’est précisément trouvé fragilisé, l’angoisse surgit, avec le risque d’une bascule psychotique. Dans ces cas extrêmes, la recherche d’une nouvelle enveloppe, remodelage de la peau, permet de contenir l’éclosion du courant psychotique grâce à la disponibilité permanente de l’incorporation du différent, identification certes coûteuse en ressources mais peut-être, à même d’éviter l’effondrement narcissique complet.

Production and purification of hydrophobin HFBII has recently been the subject of intensive research, but the yield of production needs to be further improved for a generic use of this molecule at industrial scale. In a first step, the influence of different carbon sources on the growth of Trichoderma reesei and the production of HFBII was investigated. The optimum productivity was obtained by using 40 g/L lactose. Carbon starvation and excretion of extracellular enzyme were determined as two main conditions for the production of HFBII. In the second phase, and according to the physiological mechanisms observed during the screening phase, a bioreactor set up has been designed and two modes of cultures have been investigated, i.e. the classical submerged fermentation and a fungal biofilm reactor. In this last set-up, the broth is continuously recirculated on a metal packing exhibiting a high specific surface. In this case, the fungal biomass was mainly attached to the metal packing, leading to a simplification of downstream processing scheme. More importantly, the HFBII concentration increased up to 48.6 ± 6.2 mg/L which was 1.8 times higher in this reactor configuration and faster than the submerged culture. X-ray tomography analysis shows that the biofilm overgrowth occurs when successive cultures are performed on the same packing. However, this phenomenon has no significant influence on the yield of HFBII, suggesting that this process could be operated in continuous mode. Protein hydrolysis during stationary phase was observed by MALDI-TOF analysis according to the removal of the last amino acid from the structure of HFBII after 48 h from the beginning of fermentation in biofilm reactor. Hopefully this modification does not lead to alternation of the main physicochemical properties of HFBII. [less ▲]

La figure de la déesse Héra est étroitement liée au pouvoir de Zeus, et par là même à la configuration grecque de la souveraineté. Dans sa figure de déesse en colère, Héra met en œuvre la « querelle » (éris) structurante, autrement dit elle est l’« ennemie intime » nécessaire à une bonne gestion du pouvoir. Mais la figure de l’épouse est tout aussi présente et cruciale, dans la représentation grecque de la déesse. C’est en cumulant les statuts de sœur et d’épouse qu’Héra assoit son rôle de souveraine, une souveraine dont le rang n’est pas toutefois absolu, mais relatif à celui du dieu qu’elle côtoie. [less ▲]

Some clinical series have evaluated the effect of platelet-rich plasma (PRP) in the treatment of proximal patellar tendinopathy. Although it is possible that a single infiltrative administration may prove to be an effective treatment for this indication, most of the existing studies evaluated the effects of two or three successive infiltrations. The aim of this study was to evaluate whether two infiltrations of PRP proves more effective than a single treatment. DESIGN: Prospective, randomized and comparative study of level 2. METHODS: Twenty patients suffering from chronic proximal patellar tendinopathy were enrolled into the study and split into two randomized groups (one or two infiltrations of PRP, respectively). The 3-month follow-up evaluation consisted of VAS, IKDC and VISA-P scores, along with algometer, isokinetic and ultrasounds evaluations. After 1 year, subjects were contacted to define their functional evolution. RESULTS: The concentration of the PRP used for each infiltration was similar in both groups, and contained no red or white cells. Results revealed no difference in treatment efficacy between the groups. CONCLUSIONS: The comparison between one or two infiltrations of PRP did not reveal any difference between the two groups at short to mid term. A second closely-timed infiltration of PRP to treat proximal patellar tendinopathies is not necessary to improve the efficacy of this treatment in the short term. [less ▲]

The Treynor and Mazuy framework is a widely used return-based model of market timing. However, existing corrections to the regression intercept can be manipulated through derivatives trading. We propose an adjustment based on Merton's option replication approach. The linear and quadratic coefficients of the regression are exploited to assess the cost of the replicating option that yields similar convexity for a passive portfolio. A similar reasoning applies for various timing patterns and in multi-factor models. The proposed framework induces a potential rebalancing risk and involves the delicate issue of choosing the cheapest option. We show that these issues can be overcome for reasonable tolerance levels.
