Simulation des cycles diurne et annuel des pluies en Afrique du Sud par un modèle de climat régional.
2014
7 pages; International audience; On analyse ici la capacité du modèle climatique régional non-hydrostatique WRF à simuler les cycles diurnes etannuels des précipitations en Afrique australe (0°-68°W – 5°S-48°S) pour la période 1998-2006. Les simulations sontconfrontées à un réseau de cent trois stations pluviométriques disponibles au pas de temps horaire et couvrant l'Afrique duSud, et aux données GPCP-1dd à l'échelle de l'ensemble du domaine. Cinq simulations ont été réalisées : quatre utilisentdifférentes paramétrisations de la convection atmosphérique à une résolution de 0.5 x 0.5 degré, afin de tester la sensibilitédes résultats à la physique du modèle. La cinquième expérience résout ex…
Taxonomy and conservation ofPancratium maritimum(Amaryllidaceae) and relatives in the Central Mediterranean
2015
Pancratium maritimum L. (Amaryllidaceae) is a geophyte occurring in the Mediterranean region, from the Black Sea to part of the Atlantic coast. This plant is receiving much attention from the international scientific community due to its value as a bioindicator, the potential industrial value of its chemical compounds, and its use as a commercial ornamental plant. Plant morphometry and sequences of three plastid DNA regions (rbcL, matK, trnH-psbA) were used to assess the phenotypic and genetic variability of this taxon and its closest congeneric species (in particular Pancratium linosae, from the volcanic island of Linosa) in the Central Mediterranean (Sicily, Tunisia and surrounding island…
Lawrence Kohlberg i el seu llegat
2018
espanolEn esta introduccion al monografico sobre Kohlberg y su obra, se detallan los diferentes proyectos que protagonizo – de investigacion y practica en Psicologia moral– con un amplio equipo de colaboradores, que cristalizo en el famoso «Manual de Medicion del Juicio Moral». Otra iniciativa destacable fueron los encuentros democraticos, donde se votaban los asuntos academicos; asi como la evaluacion exhaustiva de los efectos del programa mencionada, sobre alumnos y docentes, en los talleres de mediciones de entrevistas de juicios morales. Gran impacto causaria por todas partes la teoria de los seis episodios del desarrollo del razonamiento moral, asi como el desarrollo de la empatia, en …
Coaches as promoters of team cohesion
2015
The objective of this study was threefold: 1) To determine the links between the perceived coach-created motivational climate and cohesion, 2) To test a model with the following sequence: Dimensions of the perceived coach-created motivational climate → self-determined motivation → Dimensions of cohesion, and 3) To examine the meditational role of self-determined motivation in the relationship between perceived coach-created motivational climate and cohesion. Eight hundred and night young footballers (789 boys and 11 girls; M age = 11.49 ± 1.16) completed a package of questionnaires assessing the variables of interest at the beginning of the season. Bivariate correlations reveale…

Réseaux de distribution de l’énergie et sobriété énergétique des territoires, les apports d’une approche thermodynamique et métabolique des systèmes …
2017
Dans le contexte de transition énergétique et de crise environnementale actuel, les intérêts des approches territoriales et systémiques de l’énergie semblent aujourd’hui admis. Cependant et malgré les nombreuses avancées dans les domaines technologiques, en matière d’urbanisme et d’aménagement ou bien encore en termes d’approches psycho-sociales et comportementales, les courbes de consommations énergétiques peinent à s’infléchir. Fort de ce constat, nous posons l’hypothèse, sur la base d’éléments théoriques empruntés à la thermodynamique et à la biologie, du rôle potentiel que pourraient jouer les réseaux de distribution énergétique, leurs caractéristiques, leur morphologie et leur dynamiqu…
Imagining a “post-carbon” future? Climate change as represented by media and film industries
2020
This study explores current trends in representing and communicating climate change by media industries. It reviews the current literature on mainstream media narratives of climate change focusing on their naturalization of progress and their techno-optimism (e.g., as regards geoengineering). It provides insight on how the media industry’s commercial agenda is linked to the types of disseminated messages and dominant imaginaries. It compares respective codes inherent in news media and film/fictional representations of climate change on representative examples. It traces the evolution of disaster/dystopian genres that involve climate issues. It discusses the implications from such a comparat…
Solar neutrino spectroscopy in Borexino
2018
International audience; In more than ten years of operation, Borexino has performed a precision measurement of the solar neutrino spectrum, resolving almost all spectral components originating from the proton-proton fusion chain. The presentation will review the results recently released for the second data taking phase 2012–2016 during which the detector excelled by its unprecedentedly low background levels. New results on the rate of pp, 7Be, pep and 8B neutrinos as well as their implications for solar neutrino oscillations and metallicity are discussed.
Inference of proto-neutron star properties from gravitational-wave data in core-collapse supernovae
2021
The eventual detection of gravitational waves from core-collapse supernovae (CCSN) will help improve our current understanding of the explosion mechanism of massive stars. The stochastic nature of the late post-bounce gravitational wave signal due to the non-linear dynamics of the matter involved and the large number of degrees of freedom of the phenomenon make the source parameter inference problem very challenging. In this paper we take a step towards that goal and present a parameter estimation approach which is based on the gravitational waves associated with oscillations of proto-neutron stars (PNS). Numerical simulations of CCSN have shown that buoyancy-driven g-modes are responsible …
Synergies in Design and Health. The role of architects and urban health planners in tackling key contemporary public health challenges
2020
Background and aim: Important public health improvements have been achieved over the past decades, but new challenges are emerging and progress cannot be taken for granted. Urban settlements host most of the global population, but they are also sources of several threats. The aim of the paper is to investigate the role of architects and planners in contributing to overcome these critical health challenges and propose strategic actions for collaboration with the public health workforce. Methods: Taking global trends and public health challenges as starting point, a scoping literature review has been conducted to illustrate the possible synergies that architecture and public health workforce …
