Cet ouvrage s'inscrit dans le fil du travail collectif entrepris en 1995, l'Histoire de la pensée médicale en Occident (trois volumes sous la direction de Mirko D Grmek, Seuil, 1995, 1997, 1999). Il rend compte du déploiement des recherches pluridisciplinaires et transdisciplinaires de la pensée médicale et aborde les discussions et controverses actuelles sur les politiques de santé. Du fait du développement des connaissances théoriques et des innovations techniques, la notion même de soin, sous ses aspects sociaux, économiques, mais aussi (...) épistémiques, se trouve questionnée. La pensée médicale ne saurait se limiter aux données biologiques, et ses composantes spécifiquement humaines et sociales sont explorées et interrogées ici dans une perspective historique qui tient compte des découvertes du dernier siècle.

In this paper, the sociopolitical status of nurses in the Philippines is examined. The importance of nursing research in identifying the many elements that contribute to inequality among nurses is critical in the face of these problems. The positivist and interpretivist perspectives, however, have limitations that could potentially perpetuate the many forms of inequality that already exist. The idea of political competency is introduced in this tension. A critical grasp of the elements that contribute to structural inequalities and a commitment (...) to bringing about positive social changes make political competency a potential supplement to the limitations of critical theory.

From its first proposal, the Central Dogma had a graphical form, complete with arrows of different types, and this form quickly became its standard presentation. In different scientific contexts, arrows have different meanings and in this particular case the arrows indicated the flow of information among different macromolecules. A deeper analysis illustrates that the arrows also imply a causal statement, directly connected to the causal role of genetic information. The author suggests a distinction between two different kinds of causal links, (...) defined as 'physical causality' and 'biological determination', both implied in the production of biological specificity.

Chemical embryology was born in 1931 with the publication of Chemical Embryology by Joseph Needham. In the following two decades it became an innovative research project aiming at the description of the construction of the embryological structure and differentiation in biochemical terms. This research programme produced a vast amount of experimental evidence and theories on the chemical dynamics of the embryo: particularly chemical characterization of the zygote and the developing embryo, the chemical exchanges between the nucleus and the cytoplasm, the (...) significance of subcellular structures, and the role and distribution of nucleic acids within the cell. From the 1950s on, a large part of these results came to be integrated into the empirical basis of molecular biology. However, the shift from chemical embryology to molecular embryology was not just a semantic shift but a deep theoretical change, produced by the introduction of a new model of scientific explanation, based on the transmission and expression of genetic information and opposed to the biochemical definition of life.

Here we study polysemy as a potential learning bias in vocabulary learning in children. Words of low polysemy could be preferred as they reduce the disambiguation effort for the listener. However, such preference could be a side-effect of another bias: the preference of children for nouns in combination with the lower polysemy of nouns with respect to other part-of-speech categories. Our results show that mean polysemy in children increases over time in two phases, i.e. a fast growth till the 31st (...) month followed by a slower tendency towards adult speech. In contrast, this evolution is not found in adults interacting with children. This suggests that children have a preference for non-polysemous words in their early stages of vocabulary acquisition. Interestingly, the evolutionary pattern described above weakens when controlling for syntactic category (noun, verb, adjective or adverb) but it does not disappear completely, suggesting that it could result from a combination of a standalone bias for low polysemy and a preference for nouns.
