Rueff et l’analyse du chômage : Quels héritages?
No full textCet article montre que Rueff (1925, 1931) distinguait [a] un chômage « permanent » attribuable à un excès des salaires réels par rapport au rendement du travail, [b] un chômage « temporaire » attribuable à une baisse de l’activité économique liée à une diminution cyclique des prix, enfin [c] un chômage «minimal» de type frictionnel prévalant dans le fonctionnement normal de l’économie. Sur la base d’observations empiriques, Rueff suggère que le chômage de type [a] était largement dominant dans l’Angleterre des années 1920 (« loi de Rueff »). La confrontation entre cette analyse et les analyses postérieures du chômage dans la littérature permet de dégager que : (i) la courbe de Phillips et son extension avec le NAIRU est un non-héritage ; (ii) la courbe des salaires (« wage curve ») s’accorde avec la « loi de Rueff » tout en constituant un intéressant complément; (iii) l’équation d’Allais du chômage français se décalque très bien sur les trois types de chômage distingués par Rueff; (iv) bien qu’étant aujourd’hui délaissée, la théorie des équilibres temporaires à prix fixes inclut le chômage de type [a], ceci que l’on regarde le régime de chômage « classique » ou celui de chômage « keynésien » ; (v) la nouvelle micro-économie keynésienne du travail montre qu’un chômage de type [a] peut être expliqué par le comportement rationnel des agents sans faire intervenir des rigidités exogènes imposées par l’Etat ; ce résultat généralise l’idée d’un chômage de type [a] mais constitue une réfutation de la possibilité admise par Rueff d’un équilibre concurrentiel spontané sur le marché du travail en l’absence de rigidités exogènes; (vi) le modèle de concurrence imparfaite WS-PS fondé sur la négociation entre salariés et employeurs s’accorde avec les trois types de chômage [a], [b] et [c], au point où l’on peut y voir une synthèse rejoignant Rueff et Allais
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
De la lampe à la lumière en Crète minoenne (3200 – 1100 av. J.-C.)
No full text© Astrid Amadieu (illustration/graphisme). Dans le courant de l’âge du Bronze (IIIe-IIe millénaires av. J.-C.), dès 1900 av. J.-C., on assiste, en Crète, à l’émergence de palais autour desquels se forment de premières villes et une administration centralisée. Dans ce qui fut l’une des premières sociétés étatisées, la production de lampes n’a cessé de se diversifier, jusqu’à sa diminution progressive à partir de 1450 av. J.-C., moment d’une destruction généralisée et d’une présence mycénien..
A 0.12mm<sup>2</sup> Wien-Bridge Temperature Sensor with 0.1°C (3σ) Inaccuracy from -40°C to 180°C
No full text Resistor-based temperature sensors can achieve much higher resolution and energy efficiency than conventional BJT-based sensors [1], but they typically occupy more area (> 0.25 mm 2 ) and have lower operating temperatures (le 125 {circ} {C}) [2]-[4]. This work describes a 0.12mm 2 resistor-based sensor that uses a Wien-bridge (WB) filter to achieve 0.1 {circ} {C} (3 sigma) inaccuracy from - 40 {circ} {C} to 180 {circ} {C}. Compared to a state-of-the-art WB sensor [4], it occupies 6 × less area and achieves comparable relative accuracy over a 76% wider operating range.
