"Si vous êtes si malins ... " : McCloskey et la rhétorique des économistes

Référence complète : FROBERT, Ludovic (2004). "Si vous êtes si malins ... " : McCloskey et la rhétorique des économistes ; suivi de La rhétorique des sciences économiques [de Deirdre N. McCloskey]. Frédéric Regard (trad.). Lyon : ENS Editions. 126 p. ISBN 2-84788-059-3En 1983, paraît dans le très sérieux Journal of Economic Literature un article au ton pour le moins iconoclaste. Signé par un auteur jusqu'alors reconnu pour ses travaux classiques dans le domaine de l'histoire économique quantitative, ce papier traite de la rhétorique des économistes. D. N. McCloskey y assène, entre autres, que l'étude des textes économiques relève avant tout de la critique littéraire ; que les modèles mathématiques, tant prisés par les économistes, sont essentiellement métaphoriques et composent un véritable domaine poétique original ; que l'économiste de profession est, au minimum, en retard d'une révolution épistémologique par rapport à ses contemporains lorsqu'il prétend assurer son autorité scientifique sur sa capacité réelle à faire des prédictions. Un fort courant de réflexion sur la rhétorique des sciences économiques va prendre sa source dans cette bravade contre le positivisme et le scientisme ambiants. En précisant le point de départ de McCloskey, en consolidant les intuitions fécondes contenues dans son attaque en règle contre le « modernisme », en prenant parfois leurs distances vis-à-vis des aspects trop clinquants de son manifeste de 1983, quelques auteurs – dont notamment Roy Weintraub, Robert Heilbroner, Albert Hirschman – vont explorer alors plus avant les conséquences de la révolution rhétoricienne en économie. « La Rhétorique des sciences économiques » est proposé ici pour la première fois en traduction française

Distributed archive and single access system for accelerometric event data : a NERIES initiative

We developed a common access facility to homogeneously formatted accelerometric event data and to the corresponding sheet of ground motion parameters. This paper is focused on the description of the technical development of the accelerometric data server and the link with the accelerometric data explorer. The server is the third node of the 3-tier architecture of the distributed archive system for accelerometric data. The server is the link between the data users and the accelero- metric data portal. The server follows three main steps: (1) Reading and analysis of the end-user request; (2) Processing and converting data; and (3) Archiving and updating the accelerometric data explorer. This paper presents the description of the data server and the data explorer for accessing data

Bibliothèques jeunesse : quelles évolutions ?

Co-organisée avec lassociation Livres de jeunesse en fête (LJF) qui, depuis 2002, regroupe des bibliothécaires de plusieurs établissements du Loiret, cette journée détude bénéficiait du soutien de la Mairie dOrléans et de la DRAC Centre. Une cinquantaine de collègues ont pu y trouver quelques réponses pratiques à leurs interrogations toujours nombreuses

Development of the Positive Emotions Program for Schizophrenia (PEPS): an intervention to improve pleasure and motivation in schizophrenia

Objectives: The efficacy of drug-based treatments and psychological interventions on the primary negative symptoms of schizophrenia remains limited. Recent literature has distinguished negative symptoms associated with a diminished capacity to experience, from those associated with a limited capacity for expression. The positive emotions program for schizophrenia (PEPS) is a new method that specifically aims to reduce the syndrome of a diminished capacity to experience. Methods: The intervention's vital ingredients were identified through a literature review of emotion in schizophrenia and positive psychology. The program has been beta-tested on various groups of health-care professionals. Results: A detailed description of the final version of PEPS is presented here. The French version of the program is freely downloadable. Conclusion: PEPS is a specific, short, easy to use, group-based intervention to improve pleasure, and motivation in schizophrenia. It was built considering a recovery-oriented approach to schizophrenia

Myocardial infarction does not affect circulating haematopoietic stem and progenitor cell self‐renewal ability in a rat model

Given the importance of peripheral blood haematopoietic stem and progenitor cells (HPCs) in post-acute regeneration after acute myocardial infarction (MI), the aim of the present study was to investigate the number and secondary replating capacity/self-renewal ability of HPCs in peripheral blood before and 2 weeks after MI. In female Lewis inbred rats (n = 9), MI was induced by ligation of the left coronary artery, and another nine underwent sham surgery, without ligation, for control purposes. Myocardial infarction was confirmed by troponin I concentrations 24 h after surgery. Peripheral blood was withdrawn and fractional shortening and ejection fraction of the left ventricle were assessed before (day 0) and 14 days after MI or sham surgery (day 14). After mononuclear cell isolation, primary and secondary functional colony-forming unit granulocyte–macrophage (CFU-GM) assays were performed in order to detect the kinetics of functional HPC colony counts and cell self- renewal ability in vitro. The CFU-GM counts and cell self-renewal ability remained unchanged (P < 0.05) in both groups at day 14, without interaction between groups. In the intervention group, higher day 0 CFU-GM counts showed a relationship to lower fractional shortening on day 14 (ρ = −0.82; P < 0.01). Myocardial infarction did not negatively affect circulating HPC self-renewal ability, which suggests a constant regenerative potential in the post-acute phase. A relationship of cardiac contractile function 14 days after MI with circulating CFU-GM counts on day 0 might imply functional colony count as a predictive factor for outcome after infarction

Subsurface ablation of atherosclerotic plaque using ultrafast laser pulses

We perform subsurface ablation of atherosclerotic plaque using ultrafast pulses. Excised mouse aortas containing atherosclerotic plaque were ablated with ultrafast near-infrared (NIR) laser pulses. Optical coherence tomography (OCT) was used to observe the ablation result, while the physical damage was inspected in histological sections. We characterize the effects of incident pulse energy on surface damage, ablation hole size, and filament propagation. We find that it is possible to ablate plaque just below the surface without causing surface damage, which motivates further investigation of ultrafast ablation for subsurface atherosclerotic plaque removal
