Open science as a better gatekeeper for science and society: a perspective from neurolaw

2018

Results from cognitive neuroscience have been cited as evidence in courtrooms around the world, and their admissibility has been a challenge for the legal system. Unfortunately, the recent reproducibility crisis in cognitive neuroscience, showing that the published studies in cognitive neuroscience may not be as trustworthy as expected, has made the situation worse. Here we analysed how the irreproducible results in cognitive neuroscience literature could compromise the standards for admissibility of scientific evidence, and pointed out how the open science movement may help to alleviate these problems. We conclude that open science not only benefits the scientific community but also the le…

Les études hédoniques soutiennent-elles une valeur verte élevée dans le bâtiment ? Une réponse par la méta-analyse

2018

International audience; La place majeure occupée par le secteur du bâtiment dans la consommation d'énergie (40%) et les émissions de gaz à effet de serre (1/3 des émissions) explique le développement du débat scientifique axé sur la réduction de l'impact environnemental du bâtit et sur ses leviers. Ces dernières années ont notamment vu croitre une littérature considérable relative à la disposition à payer du public pour les bâtiments « verts » labélisés par des écolabels, cette « valeur verte » étant estimée dans la grande majorité des études via des modèles hédoniques. Dans cet article, nous proposons d'offrir une synthèse de ces résultats dans le cadre d'une méta-analyse portant sur plus …

L'INFLUENCE DE L'INTRUSION PERÇUE SUR LES COMPORTEMENTS DE RÉSISTANCE AUX FORMATS DE PUBLICITÉ SUR INTERNET

2012

Drawing from the theoretical framework defined by Roux (2007), this research examines the relationship between perceived advertising intrusion (Anzieu, 1994) and manifestations of consumer resistance (Hirschman, 1970). The results show that the intrusion does not significantly affect the expression or intention to return to the website. However, it influences positively defection and negatively purchase intention of the product promoted in the ad.

L’ADULTO COME SPECCHIO. MODALITÀ COMUNICATIVE E APPRENDIMENTO

2021

Numerose ricerche sull’infanzia condotte a partire dal secolo scorso, hanno mostrato come i bambini, fin dai primi mesi di vita, siano attivi e propositivi nella interazione con gli altri esseri umani. In una prospettiva educativa, di promozione dei processi di apprendimento e di sostegno alla costruzione di una immagine di sé positiva e fiduciosa nelle proprie potenzialità, sono di grande importanza le modalità comunicative e relazionali degli adulti significativi. A tali modalità farò riferimento nel mio contributo, soffermandomi sul rispecchiamento verbale e non verbale, nelle sue diverse forme, approfondendone le ragioni teoriche e metodologiche e riflettendo su come possa attuarsi una …

Promoting the Cultural Understanding of a Student in a General Education School: Teachers’ Experiences and Challenges

2020

Cultural understanding is a basis for competence-oriented general education. Teachers are responsible for applied content and methods that are used to purposefully lead school students to that result.The aim of this study is to identify actual goals for the development of teacher education curriculum, professional development, and teaching aids by investigating in-service teachers’ challenges in the successful promotion of students’ cultural understanding in general schools.The readiness of teachers to promote the cultural understanding of primary school students was explored in a mixed-methods study. The findings indicated aspects that teachers consider relevant as well as the main problem…

L’engagement des chercheurs dans la vulgarisation scientifique

2012

International audience; Quelle attitude ont les chercheurs vis-à-vis de la vulgarisation scientifique ? Voilà une question que tout médiateur scientifique est amené à se poser. Elle intéresse aussi les gouvernements et les grandes institutions scientifiques qui incitent les chercheurs à communiquer auprès du grand public et cherchent des solutions pour améliorer cette communication.Nous avons recherché des études et des enquêtes qui, depuis 1992, auraient proposé des diagnostics sur l’attitude, l’intérêt et surtout l’engagement des chercheurs dans cette pratique de vulgarisation. Notre propos s’articulera autour d’une étude clé, publiée en 2007 par Ellen Poliakoff et Thomas L Webb qui s’int…

Villes, densité et fractalité

1995

International audience; Ce bref article résumé les résultats d'analyses fractales effectuées sur les villes françaises à plusieurs dates pour deux niveaux d'observation: les tissus urbains caractérisés par la distribution spatiale des surfaces bâties d'une part, et le semis des villes de différentes tailles dans l'ensemble du territoire français d'autre part. Les méthodes de mesure sont rapidement expliquées, l'accent est mis sur la signification des nombres obtenus, leur comparaison d'une ville à l'autre et leur évolution au cours du temps.

Nonlinear Time-Series Adaptation for Land Cover Classification

2017

Automatic land cover classification from satellite image time series is of paramount relevance to assess vegetation and crop status, with important implications in agriculture, biofuels, and food. However, due to the high cost and human resources needed to characterize and classify land cover through field campaigns, a recurrent limiting factor is the lack of available labeled data. On top of this, the biophysical–geophysical variables exhibit particular temporal structures that need to be exploited. Land cover classification based on image time series is very complex because of the data manifold distortions through time. We propose the use of the kernel manifold alignment (KEMA) method for…
