Direct assessment of the sensitivity drift of SQM sensors installed outdoors
2021
Long-term monitoring of the evolution of the artificial night sky brightness is a key tool for developing science-informed public policies and assessing the efficacy of light pollution mitigation measures. Detecting the underlying artificial brightness trend is a challenging task, since the typical night sky brightness signal shows a large variability with characteristic time scales ranging from seconds to years. In order to effectively isolate the weak signature of the effect of interest, determining the potential long term drifts of the radiance sensing systems is crucial. If these drifts can be adequately characterized, the raw measurements could be easily corrected for them and transfor…
Human Nature and Economic Institutions Instinct Psychology, Behaviorism and the Development of American Institutionalism
2003
This paper explores the evolution of the psychological foundation of institutional economics between the early XXc and the 1940s. The first part deals with the rise and fall of instinct psychology. Inspired by Veblen's taxonomy of instinctive behavior, several American economists attempted to build a viable alternative to psychological hedonism of neoclassical economics then only at its infancy. In this debate we show how instinct theory came to be applied to the field now as industrial psychology. The second part discusses some of the reasons why this methodological approach began to lose momentum among leading American institutionalists. In this section we also present the emergence of be…

Los canecillos de la Capilla del Cementerio de San Juan del Hospital de Valencia
2020
In the medieval cemetery of the Historic Site of San Juan del Hospital of Valencia is housed a small funeral chapel founded in the late thirteenth century by the knight Arnau de Romaní. Along its cornice there are a series of heads of animals and humans that are one of the few sculptural vestiges inserted into the Romanesque iconographic tradition that are preserved in the city. So far they have not aroused the interest of specialists and no one has dedicated a detailed study to these curious and interesting images located in the marginal spaces of such a beautiful building. This article aims to complete this gap addressing the study of the corbels of the small temple, projecting a thematic…
Sicilia 1836: le architetture “saracene” nelle memorie di viaggio di Eugène E. Viollet-le-Duc e di Henry Gally Knight
2017
Gli anni trenta dell'Ottocento costituiscono per la Sicilia un momento decisivo nello sviluppo del dibattito sull'architettura medievale. Da una parte, infatti, i monumenti siciliani trovano in quel decennio, uno spazio editoriale a diffusione internazionale considerevole, permettendo così di amplificare gli esiti di un dibattito che nell'isola aveva radici lontane e che nel decennio precedente si era sviluppato con grande vivacità; sono gli anni in cui vedono la luce il lavoro quasi decennale di Hittorff e Zanth su L'Architecture moderne de la Sicile (1835) e la fondamentale opera del Duca di Serradifalco Del Duomo di Monreale e di altre chiese siculo-normanne (1838). All'importaza di tali…
Pedagogy-related tensions in flexibly scheduled early childhood education and care
2020
In flexibly scheduled early childhood education and care (ECEC), the timing of care depends on parents’ non-standard working hours. Multiple individual schedules and care times in a child group may cause irregularity in a child’s daily structures, and a child may miss a standard hour’s activities that are led by teachers with a pedagogical education. In this context, the significance and definition of pedagogy is vague and tensional. This study aimed at disclosing discursive tensions related to pedagogy in flexibly scheduled ECEC constructed in interviews by Finnish teachers and childcare nurses (n = 31). The analysis of the interview data followed the principles of discursive psychology. C…
Projet CHIROLUM. Comment limiter les impacts écologiques de l’éclairage artificiel nocturne le long des ILTe ? Caractérisation de l’influence des par…
2021
Ce rapport expose les résultats du projet Chirolum ayant pour objectif d'identifier des pistes de réduction des impacts écologiques de l'éclairage artificiel le long des infrastructures de transport. En prenant l'exemple de sites d'études le long de lisières forestières aux Pays-Bas et le long du Canal du Midi à Toulouse, les résultats montrent que la lumière perturbe fortement l'usage de ces continuités écologiques et infrastructures de transport par les chauves-souris, engendrant des modifications dans le comportement de vol et potentiellement des coûts énergétiques supplémentaires, ainsi qu'une diminution de la connectivité fonctionnelle pour ces espèces potentiellement préjudiciables à …
Programme-cadre FENOIR (Figurations de l’environnement nocturne des territoires réunionnais). Rapport d’étape pour le Parc national de La Réunion
2022
Soumise à une importante poussée démographique, l’île de La Réunion a vu sa population urbaine fortement augmenter – passant de 44 % de la population totale en 1975 à 95 % en 2015. Directement corrélée aux formes et dynamiques spatiales de l’urbanisation, l’empreinte lumineuse sur l’île a connu une mutation radicale ces dernières années : son emprise et sa pression ont considérablement augmenté sur l’ensemble du territoire, depuis la côte jusqu’à l’intérieur même du Parc national de La Réunion qui recouvre plus de 76 % du territoire insulaire (42 % pour la zone cœur). Acteur incontournable des enjeux environnementaux sur l’île, le Parc national a mené très tôt des actions autour des effets …
Fenêtres sur ciel étoilé
2019
International audience; L’engouement pour la création de réserves de « protection du ciel étoilé » s’étend à un nombre croissant de pays. Impulsé par les milieux de l’astronomie professionnelle et amateur, relayé par d’autres protagonistes publics et privés impliqués dans la réussite et la valorisation de la démarche, cet élan a notamment pris corps autour d’observatoires scientifiques de montagne. Figures emblématiques de l’histoire de l’aménagement de la montagne, ces observatoires ouvrent aussi un espace d’intermédiation entre nos sociétés contemporaines, technicistes et sophistiquées, et des mécanismes célestes porteurs d’enjeux environnementaux concrets.
Getting night lighting right taking account of nocturnal urban uses for better-lit cities
2018
Translated by Oliver Waine; International audience; Innovation in contemporary urban lighting has increasingly been driven by issues of sustainability. While environmental concerns focus attention on energy savings and reducing light pollution, taking account of how people use public spaces is important too, as artificial light can then be adjusted to actual needs. Following the pioneering work of Roger Narboni and Luc Gwiazdzinski, Samuel Challéat and Dany Lapostolle make the case for dedicated nocturnal city planning.
