Estimating Tree Health Decline Caused by Ips typographus L. from UAS RGB Images Using a Deep One-Stage Object Detection Neural Network
2022
Various biotic and abiotic stresses are causing decline in forest health globally. Presently, one of the major biotic stress agents in Europe is the European spruce bark beetle (Ips typographus L.) which is increasingly causing widespread tree mortality in northern latitudes as a consequence of the warming climate. Remote sensing using unoccupied aerial systems (UAS) together with evolving machine learning techniques provide a powerful tool for fast-response monitoring of forest health. The aim of this study was to investigate the performance of a deep one-stage object detection neural network in the detection of damage by I. typographus in Norway spruce trees using UAS RGB images. A Scaled…
A global experiment on motivating social distancing during the COVID-19 pandemic
2022
Significance\ud \ud Communicating in ways that motivate engagement in social distancing remains a critical global public health priority during the COVID-19 pandemic. This study tested motivational qualities of messages about social distancing (those that promoted choice and agency vs. those that were forceful and shaming) in 25,718 people in 89 countries. The autonomy-supportive message decreased feelings of defying social distancing recommendations relative to the controlling message, and the controlling message increased controlled motivation, a less effective form of motivation, relative to no message. Message type did not impact intentions to socially distance, but people’s existing mo…
Droit et gouvernance:l'apport du courant comportemental
2010
Under the dominant approach to corporate governance, the role of law is to help reduce the impact of conflicts of interest and intentional strategic behavior of the different actors, including managers. The managers' decisions that are detrimental to shareholders and other stakeholders do not all have their origin in an intentional behavior. Some of them result of misjudgment, cognitive and behavioral biases. Based on Behavioral Law and Economics, which has expanded greatly in the United States, the objective of the paper is to show that the role of law within the corporate governance system is also to contribute to "debias" managerial decisions or correct any adverse effects of these biase…
Would you mind your language, please? : Consumer Incivility on Social Media Platforms
2022
Consumer incivility on social media platforms has recently gained the attention of academic researchers. However, few studies have presented the role that consumer incivility plays in forming social media perspectives (e.g. experiencing uncivil comments or rude replies on Facebook, Twitter and Instagram). Using the stimulus-organism-response theory, this study investigated the impacts of consumer incivility on social media brand representatives’ efforts to deal with it, social media brand community participation and social media brand trust. The study also investigated the influence of social media brand representatives’ efforts to deal with consumer incivility on social media brand communi…
Biais de discrimination et statut social : une étude de terrain sur les relations intergroupes
2006
International audience; This study concerns discrimination bias in relations between work groups. As new developments in categorisation theory have shown, several factors modulate the effects of inter-group categorisation. Among these, status is viewed as introducing conflict between groups. We studied the impact of this factor in a work situation where status was not linked to power, choosing a firm in which relations between groups were conflict provoking. Three work groups within the same mobile phone firm were selected on the basis of their status : the ''Hard'' group, considered as high status in relation to the low status ''Administration'' group, and the ''Production'' group with an …
Étude exploratoire de l’effet d’un amorçage olfactif sur les biais attentionnels chez des adultes normo-pondéraux, en surpoids et obèses
2018
National audience; Introduction Hendrikse et al. [1] mettent en évidence des biais attentionnels (le fait que notre attention soit attirée par certains stimuli plus perceptivement saillants que d’autres dans l’environnement) différents selon le statut pondéral des individus. Ces biais attentionnels sont exacerbés chez les individus en surpoids et obèses face à des stimuli alimentaires à haute densité énergétique [2]. Ces biais semblent jouer un rôle dans le développement et dans le maintien de l'obésité. Notre étude se propose d’étudier les biais attentionnels chez des adultes normo-pondéraux (NP), en surpoids (SP) et obèses (OB) ainsi que les effets d’odeurs alimentaires sur ces biais, en …
Exploratory behaviour is not related to associative learning ability in the carabid beetle Nebria brevicollis
2020
Recently, it has been hypothesised that as learning performance and animal personality vary along a common axis of fast and slow types, natural selection may act on both in parallel leading to a correlation between learning and personality traits. We examined the relationship between risk-taking and exploratory behaviour and associative learning ability in carabid beetle Nebria brevicollis females by quantifying the number of trials individuals required to reach criterion during an associative learning task (‘learning performance’). The associative learning task required the females to associate odour and direction with refugia from light and heat in a T-maze. Further, we assessed learning …
Representações sociais, sens pratique, poder simbólico e o processo de construção do ser docente
2019
A partir de las elaboraciones teóricas de los fundadores del campo de investigación de las representaciones sociales, se pretende avanzar en la construcción de un diálogo entre esta teoría y la praxis social de Pierre Bourdieu, centrándose en la relación entre las representaciones sociales, la praxis sensorial (como manifestación del hábito) y el poder simbólico, dimensión ausente en el modelo moscoviciano. La base empírica a partir de la cual se desarrollan las reflexiones presentes en este artículo se apoya en investigaciones realizadas sobre el proceso de construcción del ser docente, en la realidad de algunas ciudades del nordeste brasileño. En este sentido, se destaca lo que se cree qu…
Etude du coaching d’un directeur de recherche de l’INRAE. Soutenu publiquement le 9 janvier 2023. Diplôme d’Université « Coaching & Management ». Par…
2023
The world of public research seems at first sight to be very little concerned by themanagement issues of the business world in which the right decisions must be taken and forwhich there is an obligation to perform. The very idea of coaching researchers seemsincongruous. The purpose of this study is to challenge this idea, by describing precisely whatthe profession of researcher is in the world of public research - their belonging to very complexstructures and the demanding challenges they have to face - then by studying thecontributions of cognitive-behavioural coaching methodologies. The analysis of the practiceshows that coaching based on constructivist psychology can lead to a better pra…
El enfermo de cáncer: una aproximación a su representación social O paciente de câncer: uma aproximação a suas representações sociais The cancer pati…
2010
Esta investigación tiene como objetivo el análisis de la representación social del cáncer y de los enfermos oncológicos en la población española. Para ello se entrevistaron a 200 sujetos elegidos mediante muestreo al azar. El método utilizado fue la realización de entrevistas estructuradas que contenían asociaciones libres de palabras ante términos estimulo y preguntas semicerradas. Las respuestas obtenidas son analizadas a partir de análisis descriptivos y análisis de contenido. Los resultados nos indican que existe una representación social del cáncer y del enfermo oncológico y que parte de ella sufre variaciones en función de la pertenencia a determinadas categorías o grupos sociales. Es…
