"De 1967 à 1989 des journées ordinaires de télévision", in Le Pajolec et Tillier (ed.)Des histoires, des images, Mélanges offerts à Myriam Tsikounas

2021

International audience; L'image, ou plutôt les images et les représentations, qu’elles soient matérielles ou mentales, sont au centre des essais réunis dans ce volume, qui couvre un vaste domaine allant du cinéma soviétique aux addictions, des imaginaires parisiens aux feuilletons télévisés, des figurations du crime aux mises en scène de l’histoire, et s’articule autour d’une même notion, celle de « circulations ».

Geneza ruchu ziomkowskiego w Niemczech Zachodnich (1947–1949) a źródła rewizjonizmu zachodnioniemieckiego

2018

The homeland association movement in Germany is an important element of the social and political landscape of that country. The importance of this movement and its influence upon the political system of Germany underwent evolution. The greatest importance – in social aspect, but also in political aspect – characterised the initial twenty-year period of the existence of the Federal Republic of Germany, i.e. the years 1949–1969. Numerous connections that the movement leaders had with political parties, along with the participation in holding power (the representatives of the movement sat in federal governments as well), stood as evidence that the expelled and their organisations had tangible …

Associations of near work time, watching TV, outdoors time, and parents' myopia with myopia among school children based on 38-year-old historical dat…

2021

Purpose To study the prevalence and risk factors of myopia with data from a questionnaire study conducted in 1983 among Finnish school children. Methods School children (n = 4 961) from the 1st, 5th and 8th grades of school (7-, 11- and 15-year-olds) in Central Finland were screened for vision followed by a questionnaire, which was returned by 4 352 (87.7%) participants. Myopia was categorized based on the questionnaire. Items concerned daily time spent on near work and outdoor activities, excluding time spent at school, watching TV and parental myopia and the associations of myopia with these factors were studied. Results The prevalence of myopia was 3%, 15% and 27% among the 7-, 11- and 1…

Krustotās un nekrustotās stereoredzes izmaiņas pēc LASIK operācijas

2021

Maģistra darbs uzrakstīts angļu valodā uz 37 lappusēm. Tas satur 10 attēlus, 9 tabulas un darbam ir 49 atsauces uz literatūras avotiem. Pētījuma mērķis bija novērtēt krustotās un nekrustotās disparitātes stereoredzes asumu pirms redzes refraktīvās operācijas, divus, četrus un sešus mēnešus pēc operācijas. Pētījumā piedalījās 102 acu klīnikas pacienti – 65 sievietes un 37 vīrieši vecumā no 19 līdz 45 gadiem. Visiem bija miopija vai miopija ar astigmatismu. Jaunais izveidotais izkliedēto punktu globālais stereoredzes datorizētais tests dod iespēju novērtēt abus disparitātes veidus. Rezultātu analīzē tika secināts, ka nav novērojamas statistiski būtiskas izmaiņas stereoredzes asumā pirms un pē…

Hydro-mechanical modelling of a natural slope affected by a multiple slip surface failure mechanism

2009

A coupled hydro-mechanical formulation is presented for the analysis of landslide motion during crisis episodes. The mathematical formulation is used to model a natural slope affected by a multiple slip surface failure mechanism, in which pore water pressure evolution was identified as the main cause for movement accelerations. An elasto-plastic constitutive model is adopted for the behaviour of slip surfaces. Material parameters are obtained by combining the available laboratory tests and the back analysis of some crisis episodes. After being calibrated and validated, the model is applied to improve the understanding of the physical processes involved and to predict the landslide behaviour…

An aposematic colour‐polymorphic moth seen through the eyes of conspecifics and predators – Sensitivity and colour discrimination in a tiger moth

2018

Although predation is commonly thought to exert the strongest selective pressure on coloration in aposematic species, sexual selection may also influence coloration. Specifically, polymorphism in aposematic species cannot be explained by natural selection alone. Males of the aposematic wood tiger moth (Arctia plantaginis) are polymorphic for hindwing coloration throughout most of their range. In Scandinavia, they display either white or yellow hindwings. Female hindwing coloration varies continuously from bright orange to red. Redder females and yellow males suffer least from bird predation. White males often have higher mating success than yellow males. Therefore, we ask whether females ca…

Transparency reduces predator detection in mimetic clearwing butterflies

2019

International audience; Predation is an important selective pressure and some prey have evolved conspicuous warning signals that advertise unpalatability (i.e. aposematism) as an antipredator defence. Conspicuous colour patterns have been shown effective as warning signals, by promoting predator learning and memory. Unexpectedly, some butterfly species from the unpalatable tribe Ithomiini possess transparent wings, a feature rare on land but common in water, known to reduce predator detection.We tested if transparency of butterfly wings was associated with decreased detectability by predators, by comparing four butterfly species exhibiting different degrees of transparency, ranging from ful…
