Poésie et science classique : la théorie cartésienne des tourbillons dans Les Principes de philosophie (1716) de C.-C. Genest
International audienceEn 1716, Charles-Claude Genest publie Les Principes de philosophie, un poème de plus de 6000 vers dans lequel il expose la physique cartésienne. À cette époque, les théories de Descartes sont en déclin, tandis que celles de Newton commencent à dominer. Malgré les critiques de Voltaire, qui juge que Genest n'aurait en commun avec Lucrèce "que le fait de versifier une philosophie largement erronée", l'œuvre de Genest reste emblématique des relations entre poésie, philosophie et science au XVIIe siècle. En versifiant la théorie des tourbillons, Genest crée une poésie didactique et scientifique, qui décrit les causes, effets et propriétés des phénomènes naturels. Son œuvre présente aussi les tourbillons comme un jeu poétique. En effet, la poétisation de l'idée de tourbillon met en valeur le tourbillon des mots, créant un art du langage en mouvement, dans un jeu poétique où la forme et le sens s'entrelacent

Manager-Employee Communication During a Crisis: The Missing Link: Emerald Highly Commended Paper – Academic CCI Conference, Wroxton, 4th -7th June 2010
Purpose – To investigate the effectiveness of internal communication during a crisis by comparing how Italian companies communicated to employees during the 2008-2009 global financial crisis and how employees interpreted these efforts.
Design/methodology – Interviews to internal communication managers and employees; two focus groups and a survey involving internal communicators.
Findings - Results indicate a misalignment between what communicators meant to communicate and what employees perceived. Companies planned excellent communication, widely used official instruments and depicted the crisis as an opportunity, while employees complained about clarity of messages and listening, disliked hierarchical communication and accused their companies of opportunism .
Research implications – Further research is needed to explore the antecedents of effective manager-employee sensemaking process during a crisis.
Practical implications –To reduce misalignment companies should reinforce trust relationships before a crisis occurs and should focus on open and continuous listening during a crisis
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

A nondestructive investigation of inserts in lightweight composite panels by ultrasonic C-scan and infrared thermography
In the aeronautical industry, there is an increasing need for lightweight composites above all for the internal design. In this regard, the final products should not contain any inclusion of foreign material in order to not compromise both the aesthetical beauty and the mechanical properties subjected to vibrational loads. In this work, the infrared thermography (IRT) and the ultrasonic C-scan (UT) methods were used to retrieve the unknown positions of sub-superficial inserts in five lightweight composite panels. They were randomly inserted during the manufacturing stage. In particular, the samples investigated herein are three glass fiber reinforced polymers (GFRP) and two carbon fiber reinforced polymers (CFRP) used as laminates or as skins for honeycombs. They were provided by the Società Elicotteristica Italiana (S.E.I.), Monteprandone (Italy). An example is reported in Fig. 1. It shows both the schematization of the cross-section and the front view of a honeycomb core (HC) covered with two skins of GFRP. A comparison between two different approaches centered on square pulse and flash thermographic scenarios is reported. The raw thermograms were processed by using advanced techniques such as the principal component thermography (PCT) and the partial least square thermography (PLST) which enhanced the visibility of the defects. In addition, the UT method applied both in reflection and in transmission modes were showed interesting advantages from a diagnostic point-of-view above all when its results are compared with the thermographic results. Fig. 2 shows the clear detection (see the blue area) of a defect realized in plastic material, having an unknown size, and positioned inside the HC. Pros and cons of both methods when applied on lightweight composite panels will be in-depth explained into the final manuscript
