A Probabilistic Classification Procedure Based on Response Time Analysis Towards a Quick Pre-Diagnosis of Student's Attention Deficit
2019
[EN] A classification methodology based on an experimental study is proposed towards a fast pre-diagnosis of attention deficit. Our sample consisted of school-aged children between 8 and 12 years from Valencia, Spain. The study was based on the response time (RT) to visual stimuli in computerized tasks. The process of answering consecutive questions usually follows an ex-Gaussian distribution of the RTs. Specifically, we seek to propose a simple automatic classification scheme of children based on the most recent evidence of the relationship between RTs and ADHD. Specifically, the prevalence percentage and reported evidence for RTs in relation to ADHD or to attention deficit symptoms were t…

La inhibición, el autocontrol emocional, la memoria de trabajo y la supervisión ¿predicen las manifestaciones típicas de adultos con TDAH?
2019
Introducción. Los déficits en inhibición, control emocional, memoria de trabajo y supervisión se han evidenciado en numerosas investigaciones focalizadas en el trastorno por déficit de atención con hiperactividad (TDAH), pero la información sobre su posible influencia diferencial en las manifestaciones características del trastorno es escasa. Objetivos. El presente estudio se propuso analizar las relaciones de las funciones ejecutivas de regulación (inhibición y control emocional) y metacognitivas (memoria de trabajo y supervisión) con manifestaciones del TDAH y determinar el poder de predicción de esas cuatro funciones ejecutivas en dichas manifestaciones. Método. Sesenta y un jóvenes adul…
Money creation and the state : A critical assessment ofchartalism
2004
International audience; The article discusses various issues related to money creation and the state. Chartalists believe that attempts at separating the central bank's and the treasury's functions is merely confused discussion. Indeed, as economist L. Wray clearly states in response to previous critiques, it should be obvious, but it usually does not appear to be so that central bank liabilities do not differ in any significant degree from treasury liabilities; in other words, they can treat both as essentially high powered money or liabilities of the state. In this sense, Wray proposes to simply consolidate the central bank and the treasury, calling the conglomerate the State, and combine…

Black currant project: Multidisciplinary approach to agro-ecological measures
2022
The decline of wild pollinators leads to a drastic drop in the associated ecosystem service, resulting in significant lossesin agricultural yields. The production of blackcurrant “Noir de Bourgogne” could potentially be tripled, if populationsof wild pollinators were restored. Various agroecological measures beneficial to pollinators are discussed here, as wellas ongoing experimental tests. We discuss the practical possibilities of implementing these measures by blackcurrantgrowers as well as the technical locks that still exist. The return to an agroecological equlibrium for which pollinationbecomes again a free ecosystem service for agriculture, requires the integration of multiple agroec…
How does pea (Pisum sativum) recover from water deficit?
2019
International audience; Pea (Pisum sativum), like other legumes, has the unique ability to fix atmospheric dinitrogen (N2) via symbiosis with soil bacteria known as rhizobia in root nodules. This particular feature makes the pea crop an essential component of sustainable cropping systems because of the reduction of nitrogen fertilizers it affords. However symbiotic nitrogen fixation (SNF) is very susceptible to abiotic stresses and particularly to water deficit, which is becoming an increasingly common threat in the current context of climate change. Water deficit impacts negatively SNF (Prudent et al., 2016), affecting both nodule number and growth (i.e. structural components of SNF) and t…
A holistic overview of the impact of sulfur deficiency in pea facing water deficit
2022
We report on the interplay between water deficit and sulfur deficiency, two constraints that are increasingly faced by crops due to climate change and low-input agricultural practices. In particular, we aim at better understanding the role of sulfur nutrition in the trade-off between seed quality establishment and plant stress tolerance in pea (Pisum sativum L.), a grain legume crop which has a pivotal role to play in both agroecological and food transitions. Like other legumes, pea is able to accumulate large amounts of seed proteins even in the absence of nitrogen fertilizers thanks to its symbiosis with N2-fixing soil bacteria. In this study, we deprived pea plants (cv. Caméor) of sulfur…
Capability of a high resolution hydroclimatic modelling chain to simulate soil water deficit indices for Douglas-fir and common Beeches over Burgundy.
2016
During the 2003 drought and heat wave event, douglas-fir and common beech stands in Burgundy have been heavily affected, and presented symptoms of dieback and mortality. This event seems to be the first occurrence of expected climatic changes in the near future and questions their sustainability in Burgundy since their climate vulnerability is mainly due to the amplitude and accumulated water constraints exercised during their growing cycle. In the context of climate change and in order to provide information to forest managers who partly rely on a mapping of the climatic constraints until the end of this century, this work explores the ability of a high resolution hydroclimatic modelling c…
