Milieux professionnels et FASP médicale : de l’autre côté du miroir
2004
Le but de cette étude, est de mettre en lumière et d’analyser les relations entre les milieux professionnels de la médecine et la fiction à substrat professionnel (FASP). Il est convenu de dire que les medical thrillers, dont les caractéristiques principales en tant que sous-groupe générique de la FASP sont présentées ici, offrent un reflet plutôt fidèle du monde de la médecine. L’auteur montre l’intégration en profondeur du discours et des pratiques de la communauté médicale dans la trame paratextuelle, narrative et linguistique des romans à suspense à dominante médicale. Afin de mieux comprendre les relations entre l’environnement professionnel et l’œuvre de fiction, l’auteur présente les…

Risk Factors for Parental Burnout among Finnish Parents: The Role of Socially Prescribed Perfectionism
2019
Abstract Objectives Although parental burnout can have detrimental consequences to families, the investigation of the syndrome is still in its infancy. The present study investigated what are the key family background variables that contribute to parental burnout among Finnish parents. Moreover, we investigated how self-oriented and socially prescribed perfectionism uniquely and interactively relate to parental burnout over and above the impacts of background variables. Methods Questionnaire-based data was collected from 1725 parents (91% mothers) and analyzed using structural equation modeling (SEM). Results The results showed that when several family- and child-related background variable…
Rikoksista tuomitut naiset : yhteisöstä erottaminen ja takaisinliittymisen mahdollisuudet
2019
Tutkimus käsittelee yhteisöstä erottamisen ja siihen takaisinliittymisen mahdollisuuksia rikostaustaisten naisten elämässä. Tutkimuksen kohteena ovat rikostaustaisten naisten kertomukset elämänkulustaan. Tutkimuksessa analysoidaan naisten kertomuksia siirtymäriittiteorian eli yhteisöstä erottamisen, liminaalin ja takaisinliittämisen näkökulmasta. Aineisto on kerätty haastattelemalla 18 naista, jotka haastatteluhetkellä olivat joko suorittamassa vankeusrangaistustaan, ehdonalaisen vapauden valvonnassa tai rangaistuksensa suorittaneet. Aineiston analyysissa on käytetty narratiivista lähestymistapaa sekä Greimasin aktanttimallia. Aineiston analyysissa esiin nousevia keskeisiä teemoja ovat päih…
The effect of spatial and temporal scale on camouflage in North African rodents
2022
Abstract Background matching, a common form of camouflage, is a widespread anti-predator adaptation that hinders detection or recognition by increasing the resemblance of prey to its environment. However, the natural environment is complex and both spatially and temporally variable, which constrains effective background matching as an anti-predator strategy. Here, using remote sensing data (publicly available satellite imagery), we investigated how variation of habitat parameters predicts background matching in 16 Sahara–Sahel rodent species across spatial and temporal scales. All fur colour parameters (hue, saturation and brightness) strongly matched the respective habitats of the differen…
Behind the scenes of artificial intelligence: a study of micro-work platforms in France
2019
Este artículo es una versión resumida del informe “Le Micro-travail en France. Derrière l’automatisation de nouvelles précarités au travail?» This article is a summarized version of the report "Le Micro-travail en France. Derrière l’automatisation de nouvelles précarités au travail?" .; International audience; Micro-work internet services allocate small, standardized tasks of data generation and annotation to crowds of providers. The outputs are mainly used to produce artificial intelligence solutions. It is an exemplary instance of the “platformization” of the economy, and of the transformations of labour that digital technologies bring about. To uncover the conditions under which micro-wo…
In situ measurements of background aerosol and subvisible cirrus in the tropical tropopause region
2002
[1] In situ aerosol measurements were performed in the Indian Ocean Intertropical Convergence Zone (ITCZ) region during the Airborne Polar Experiment-Third European Stratospheric Experiment on Ozone (APE-THESEO) field campaign based in Mahe, Seychelles between 24 February and 6 March 1999. These are measurements of particle size distributions with a laser optical particle counter of the Forward Scattering Spectrometer Probe (FSSP)-300 type operated on the Russian M-55 high-altitude research aircraft Geophysica in the tropical upper troposphere and lower stratosphere up to altitudes of 21 km. On 24 and 27 February 1999, ultrathin layers of cirrus clouds were penetrated by Geophysica directly…
Camouflage accuracy in Sahara-Sahel desert rodents
2020
1.Camouflage helps animals to hide from predators and is therefore key to survival. Although widespread convergence of animal phenotypes to their natural environment is well established, there is a lack of knowledge about how species compromise camouflage accuracy across different background types in their habitat. 2.Here we tested how background matching has responded to top‐down selection by avian and mammalian predators using Sahara‐Sahel desert rodents in North Africa. 3.We show that the fur coloration of several species has become an accurate match to different types of desert habitats. This is supported by a correlation analysis of colour and pattern metrics, investigation of animal‐t…
Improved camouflage through ontogenetic colour change confers reduced detection risk in shore crabs
2019
Abstract Animals from many taxa, from snakes and crabs to caterpillars and lobsters, change appearance with age, but the reasons why this occurs are rarely tested.We show the importance that ontogenetic changes in coloration have on the camouflage of the green shore crabs (Carcinus maenas), known for their remarkable phenotypic variation and plasticity in colour and pattern.In controlled conditions, we reared juvenile crabs of two shades, pale or dark, on two background types simulating different habitats for 10 weeks.In contrast to expectations for reversible colour change, crabs did not tune their background match to specific microhabitats, but instead, and regardless of treatment, all de…
The Eurasian Treecreeper (Certhia familiaris) has an effective camouflage against mammalian but not avian vision in boreal forests
2022
A well-known example of visual camouflage in birds is the plumage coloration of the Eurasian Treecreeper Certhia familiaris, yet this species’ camouflage has never been objectively quantified. Here, we quantify treecreeper camouflage in its boreal forest habitat, test whether treecreepers better match tree backgrounds at nest site, territory or habitat spatial scales, and explore which common tree species provide the best background match. Using photographic data of the birds and forested backgrounds, we test their background match using human, ferret and avian vision modelling. We found that a treecreeper’s wing and mantle provided closest background matching, whereas the wing stripe and t…
