The giant panda is cryptic
2021
The giant panda (Ailuropoda melanoleuca) is an iconic mammal, but the function of its black-and-white coloration is mysterious. Using photographs of giant pandas taken in the wild and state-of-the-art image analysis, we confirm the counterintuitive hypothesis that their coloration provides camouflage in their natural environment. The black fur blends into dark shades and tree trunks, whereas white fur matches foliage and snow when present, and intermediate pelage tones match rocks and ground. At longer viewing distances giant pandas show high edge disruption that breaks up their outline, and up close they rely more on background matching. The results are consistent across acuity-corrected c…
Coaches’ Perceptions of Athletes’ Psychobiosocial States : The Case of Three Tennis Coach-Athlete Dyads
2018
Considering the limited attention paid to interpersonal aspects of emotions, this study explored coaches’ perceptions of athletes’ performance-related states and how they used this information for its regulation. Using a case study approach, three coach-athlete dyads from competitive tennis took part in one-on-one semi-structured interviews. Individualized profiling of psychobiosocial states was used to assess athletes’ states in most and least successful performances and as a way of data triangulation. Findings indicated that the coaches paid attention to bodily, motor-behavioural, and operational components of a performance state, and used this information to appropriately adapt their res…
Zachowania zdrowotne a poczucie własnej skuteczności i kontrola emocji u pacjentów z chorobami nowotworowymi
2018
Wprowadzenie. Indywidualne cechy osobowości każdego człowieka warunkują odmienną reakcję na wiadomość o chorobie nowotworowej, wpływają na wyniki jej leczenia, dalsze rokowanie, a także jakość życia chorego. W tym kontekście istotną rolę odgrywają zdolności kontroli emocji oraz poczucie własnej skuteczności, które jest siłą przekonania, że poprzez realizację określonych działań można osiągnąć wyznaczone cele. Cel. Ocena związku pomiędzy poczuciem własnej skuteczności, kontrolą emocji a zachowaniami zdrowotnymi u pacjentów cierpiących z powodu choroby nowotworowej. Materiały i metody.

How news affect the trading behavior of different categories of investors in a financial market
2015
We investigate the trading behavior of a large set of single investors trading the highly liquid Nokia stock over the period 2003-2008 with the aim of determining the relative role of endogenous and exogenous factors that may affect their behavior. As endogenous factors we consider returns and volatility, whereas the exogenous factors we use are the total daily number of news and a semantic variable based on a sentiment analysis of news. Linear regression and partial correlation analysis of data show that different categories of investors are differently correlated to these factors. Governmental and non profit organizations are weakly sensitive to news and returns or volatility, and, typica…
Task-focused behaviour and mothers' causal attributions in relation to dyslexia : a follow-up from age 8 to age 20
2018
Children with dyslexia tend to find reading stressful. Coping responses, such as task-focused and avoidant behaviours, can help mitigate the stress. Task-focused behaviour is associated with reading development, with others’ at-tributions of success and failure linked to task-focused behaviour. The present study aims to examine whether differences in task-focused behaviour between those with dyslexia and those without dyslexia exist in childhood (age 8) and persist in adolescence (age 15) and early adulthood (age 20). The study also aimed to understand the relationship between mothers’ causal attributions of their 15-year-old adolescents’ school successes and fail-ures and task-focused beha…
Modelling the early determinants of food preferences in the OPALINE cohort
2012
Diaporama confidentielDiaporama confidentiel; The OPALINE project aimed at understanding the determining factors of the development of food preferences and eating behaviour up to the age of 2 years by following a cohort of children with a longitudinal recording of perinatal and postnatal feeding experiences, of children’s sensitivity to food tastes and odours and of parental feeding practices. The aim was to conjointly analyse the datasets to draw an overall picture of these potential determinants of food preferences and of their relative weight over the course of the first two years.The recruitment of a cohort of children (N=314) was conducted thanks to the help of local health and childho…

Early development of taste and flavor preferences and consequences on eating behavior
2018
The first 1000 days of life constitute an important period for development of health and eating behavior, in particular because the mode of feeding drastically evolves, which involves that the child has to learn “how” to eat, but also “what” to eat, “how” much food to eat. After birth, when foods are orally exposed, infants discover the intrinsic properties of foods, with a variety of tastes, flavors, textures, as well as energy densities. Here we focus on deciphering the involvement of taste and olfaction in the early establishment of eating behavior. In the OPALINE French birth cohort (Observatory of Food Preferences in Infants and Children), taste and flavor preferences were studied in c…
