Visibility without voice: Media witnessing irregular migrants in BBC online news journalism
2016
In the analysis of journalistic representation of irregular migration to Europe, rather little attention is given to the variation of modes and genres of journalism. Most studies focus on text in ‘old media’ and the news genre. This article analyses affordances of different modalities and genres of online journalism in framing irregular migrants. Media framing in BBC online news coverage of a mediatised conflict in Spain, defined as a ‘migration crisis’, is analysed with multimodal social semiotics. While mediation makes global audiences witness tragedies at Europe's borders and online journalism affords more voice and deliberation for migrant sources, the frames of threat and victim domina…
Snack portion size choice, expectations and actual experiences in children: the interplay of healthiness, hunger, and sensory food imagery
2018
International audience
Huoli kuvasta : merkitys, mieli, materiaalisuus
2017
This research is a hybrid of a monograph and a multiple-article dissertation. Its theoretical starting point is a phenomenologically based view of the being of the image, in which Georges Didi-Huberman´s work plays a central role. For him, as well as for Mieke Bal, a historical work of art is never only in the distant past only but also exists in the present actuality. This makes the temporality of the Image extremely complex. The Image can be encountered only “pre-posterously” (Bal) or by reading it “against the grain” (Didi-Huberman). The Image is necessarily anachronistic; it is not in time but opens up time. This fact should be taken into account not only in art history, but also in art…
Tatouage des Images Médicales en Vue d'Intégrité et de Confidentialité des Données
2010
International audience; Dans l'objectif de contribuer à la sécurité de partage et de transfert des images médicales, nous présentons dans ce travail la méthode de tatouage multicouche. Cette dernière consiste à insérer dans l'image médicale les informations qui concernent la signature de centre hospitalier et les données du patient. Elle doit permettre d'assuré l'intégrité, la confidentialité des données lors de leur partage, et la robustesse aux différents types d'attaques (compression JPEG, Copier-coller, transformations géométriques, etc).
Analysis of the perceived self-‐efficacy in the use of ICT of pre-‐ service primary and preschool teachers
2017
La formación del profesorado en el uso de las TIC es un aspecto importante para conseguir una verdadera integración de las TIC en la educación. Según el modelo TPACK, esta formación no debe limitarse a contemplar de manera separada los aspectos relacionados con las TIC, el contenido curricular y la metodología. En el presente estudio se explora la percepción de autoeficacia en cuanto al uso de las TIC en el aula de una muestra de 107 estudiantes de los grados de Maestro/a en Educación Infantil y en Educación Primaria. Para ello se emplea una traducción del cuestionario para la autoevaluación de las competencias TIC elaborado por Tondeur et al. (2016). Los resultados del estudio muestran que…
Frazeologizmy w internetowych grach werbalno-wizualnych
2021
Obraz zdominował nasze życie, stał się jego nieodłącznym elementem, wdziera się do niego z ekranów telewizorów, telefonów, komputerów. Użytkownicy internetu korzystają z możliwości, jakie daje im komputer, i chętnie tworzą teksty łączące w sobie elementy werbalne i graficzne. Jednym z najpopularniejszych polikodowych gatunków internetowych są demotywatory. Połączenie w nich dwóch kanałów: werbalnego i ikonicznego powoduje wzmocnienie siły ich oddziaływania. Często w werbalnej części demotywatorów są wykorzystywane frazeologizmy i skrzydlate słowa. Połączenie ich z elementem graficznym powoduje ich defrazeologizację oraz grę językową z wykorzystaniem wieloznaczności i homonimiczności wyrazów.
"Last Signification Bits" Method for Watermarking of Medical Image
2011
International audience; In this paper, we present a new approach for watermarking of medical image that we are trying to adapt to telemedicine. This approach is intended to insert a set of data in a medical image. These data should be imperceptible and robust to various attacks. It's containing the signature of the original image, the data specific to the patient and his diagnostic. The purpose of the watermarking method is to check the integrity and preservation of the confidentiality of patient data in a network sharing. This approach is based on the use the LSB (least significant bits) of the image and tools borrowed from cryptography.
Näkyvä lapsuus : lapsuuskuva havainnointipäiväkirjassa ja television mainoskuvissa
2017
This research addresses images of childhood in the context of media and children´s everyday lives. Images of childhood reproduced by young children themselves and by their parents and day-care personnel, and in television advertising were investigated. Representations are studied as social, cultural and historical entities that are formed in the course of everyday life. The question is asked, what kind of childhood is (re)produced in children's everyday lives and in the media context, and how are the representations created using visual and textual materials connected with the cultural imagery of childhood? To collect child observations and descriptions of daily lives as provided by adults …
On Temporal Aspects in Cross-Cultural e-Collaboration Between Finland and Japan Research Teams
2018
Time is an essential dimension in cross-cultural e-collaboration among research project teams. Understanding temporal aspects and project dynamics in cross-cultural research e-collaboration and related processes can improve team members' skills in cross-cultural communication and increase their cultural competence. The present case cultures are Finnish and Japanese, and the case universities are the University of Jyväskylä (Finland) and Keio University (Japan). Three issues are addressed in this article. First, cultural dimensions and time models in the cross-cultural e-collaboration context are discussed. Second, temporal aspects related to e-collaboration activities are introduced. Third,…
Caractérisation fine du climat en serre expérimentale - Cas de la plateforme 4PMI de l’INRA de Dijon
2019
Les conditions environnementales dans lesquelles sont cultivées les plantes influent grandement surleurs caractéristiques observables, i.e. leur phénotype. Les conditions environnementales d’une serren’étant pas homogènes, elles peuvent induire un biais lors de l’analyse des résultats de phénotypage.Afin de mieux contrôler ce biais, la plateforme « Plant Phenotyping Platform for Plant Micro-organismsInteractions » (4PMI) hébergée par le Centre INRA de Dijon a mis en place un système decaractérisation du climat de chaque plante dans ses serres. Le développement de ce protocole a faitl’objet de ce stage. Dans un premier temps un système de collecte et de gestion des donnéesclimatiques produit…
