Tracking Ideal Varieties and Cropping Techniques for Agroecological Weed Management: A Simulation-Based Study on Pea.
2022
Book of abstract p.110-111; International audience; Pea (Pisum sativum L.) is a key diversification crop but current varieties are not verycompetitive against weeds. The objective of this study was to identify, depending on the typeof cropping system and weed flora, (1) the key pea parameters that drive crop production,weed control and weed contribution to biodiversity, (2) optimal combinations of peaparameter values and crop-management techniques to maximise these goals. For this, virtualexperiments were run, using FLORSYS, a mechanistic simulation model (Colbach et al., 2021,Field Crops Res 261:108006). This individual-based 3D model simulates daily crop-weed seedand plant dynamics over t…
Environmental spillovers and their impacts on housing prices: A spatial hedonic analysis
2015
This paper investigates the spatial dimension of environmental factors on housing prices. We develop spatial hedonic models to estimate the implicit prices of various environmental attributes. The spatial dimension can be interpreted in terms of local or global spillovers. We conduct an empirical study in the Loire estuary (France). We focus on natural areas and more artificialized ones (ocean frontage, wetlands, rivers, and noisy roads). We show that, depending on the spatial model used, the implicit price is more than just the estimated coefficient value and combines both a feedback effect and a propagation effect.
Uptake of triticonazole, during imbibition, by wheat caryopses after seed treatment
1997
The uptake of 14C-labelled triticonazole by wheat caryopses during imbibition was investigated. The uptake from an aqueous solution appeared to be driven by mass flow rather than by accumulation in seed lipids. During treatment with a liquid seed-dressing preparation of triticonazole, c. 1 μg triticonazole per caryopsis (2·4% of applied triticonazole) entered the seed. During germination in soil, another c. 1 μg triticonazole per caryopsis entered the seed in 24 h. In killed seeds, no penetration was observed between 24 h and 72 h after the beginning of imbibition. After seed treatment and imbibition in soil, triticonazole appeared to be located in the seed coats and embryo, but not in endo…

From the Scientific Revolution to Rock: Toward a Sociology of Feedback
2007
International audience; For many people, rock's primal scene is set in a recording studio, in Memphis, in 1954. There, three musicians (Scotty Moore, Bill Black and Elvis Presley), a producer/engineer (Sam Phillips) and a tape recorder (Ampex) create a song ('All Right Mama') that durably transforms the physiognomy of music. In this article, I examine the technological, political and intellectual circumstances that made this event possible. One word holds pride of place in my discussion: feedback, a mode of organisation that originated in British scientific laboratories of the eighteenth century. 2 1 A great " thank you " to my sciences studies' mentors Jean-Paul Gaudillière and Ilana Löwy,…

Evaluating the Public's Reaction to Simulated Alerts on Mobile Phones in France: Scale Effects, and Challenges
2022
International audience; In case of sudden and extreme life-threatening situation, the most efficient system fulfils the requirement of mobile phone emergency alerting information services. But how much information and what type of content must be used in a textual message, and how adapt this alert to a large audience and diversified contexts? This paper proposes to address this challenge, 1) by presenting results obtained in France during simulated "alerting days", with sampling revealing the perception and understanding of SMS and CB by a non-specialized audience (161 respondents), and 2) by comparing findings obtained in different contexts (students and teaching staff in a university, cri…
Sur l’importance des disques et du recording dans la musique populaire et la techno
2005
International audience; Depuis qu'Edison a inventé le phonographe un nouveau mode de stockage de la musique est venu s'ajouter au corps des individus et à la notation : les disques. Cela signifie, qu'en plus d'aller à la musique (jouer d'un instrument ou assister à un évènement musical), la musique vient à nous. C'est donc par l'intermédiaire des enregistrements que, dans une très grande mesure, nous découvrons, aimons, apprenons et transmettons la musique. Autrement dit, ce que l'on appelait jadis, et assez improprement, la culture orale, a trouvé son médium, un objet léger et bourré d'informations précieuses qui circule et s'échange facilement.
