Apprendre à manger. Sémiotique des objets de table pour enfants

2021

The subject of children at the table is related to that of conviviality on two levels. Firstly, at the level of the acquisition of social rules concerning the ways of being at the table, the codes of the meal, the recognition of appropriate behaviour in different contexts (at home, outside, formal, informal, etc.), in short, the "have to". Secondly, at the level of the acquisition of a general know-how, represented by all the somatic behaviours necessary for the consumption of the meal: learning to chew solid food, to drink from a glass, to use cutlery, to handle plates, bowls, soup plates, and so on. In this essay, we will analyse table objects designed for children (glasses, cutlery, plat…

Introduction to the semiotics of the text

2021

This books aims to demonstrate how semiotic models of textual analysis can be used to study any social reality or cultural process. In addition, it shows how semiotic models work by using examples from everyday life and social praxis, communicative processes and modes of consumption, online interactions and cross-media procedures, political experiences and scientific universes.

Bcl-xL as a Modulator of Senescence and Aging

2021

Many features of aging result from the incapacity of cells to adapt to stress conditions. When cells are overwhelmed by stress, they can undergo senescence to avoid unrestricted growth of damaged cells. Recent findings have proven that cellular senescence is more than that. A specific grade of senescence promotes embryo development, tissue remodeling and wound healing. However, constant stresses and a weakening immune system can lead to senescence chronicity with aging. The accumulation of senescent cells is directly related to tissue dysfunction and age-related pathologies. Centenarians, the most aged individuals, should accumulate senescent cells and suffer from their deleterious effects,…

Early development of hedonic and motivational aspects of eating behaviour

2015

Eating is essential for survival. However, the newborn is not an autonomous eater, and has to learn ‘how', ‘what', ‘when', and ‘how much' to eat quickly enough to ensure harmonious growth and development. In other nutritional areas, it has been shown during the past 20 years that early experiences are likely to impact long-term health outcomes. Thus, it appears fundamental to understand the early development of hedonic and motivational aspects of eating behaviour. This presentation will describe several studies conducted in our group during the past 10 years, in order to gain more knowledge about the development of what and how much children eat, in relation with food sensory and nutritiona…

Players' progression through GraphoGame, an early literacy game: Influence of game design and context of play

2019

Researchers of serious games frequently investigate outcomes of play but overlook the underlying game-design components that drive those outcomes. In this paper, I aim to show how game design and context of play influence progression through GraphoGame, an early-literacy game. This is done by means of two intersecting studies. The first study shows how the game can be represented by a model that explicitly hypothesizes how the interaction between the player and the game drives progression. The second study explores user data generated by first graders (N = 137) who played the game over a period of 25 weeks as part of early literacy instruction. The juxtaposition of these two studies reveals…

Modular Service Design of Information Technology-Enabled Services

2022

The literature has proposed ways to modularize information-technology-enabled services (ITeS) with limited success. We argue that applying design principles (DPs) can address this gap and revitalize the service modularization literature. With a qualitative research study, we develop exemplar DPs and a set of prioritized DPs for ITeS. We contribute to the literature by demonstrating how complex service systems, specifically ITeS, can be modularly designed. Our DPs show how different ITeS design elements or service attribute combinations impact the outcome-driven design of service experience. Based on the findings, we present a modular service design framework and a service design method tha…

L’habitat du Néolithique final de Quinssaines, Le Bournadiau : approche spatiale et fonctionnelle d'un site au Nord-Ouest de l'Allier.

2011

A late Neolithic settlement was explored during excavations in the northeast of the Allier département, at Bournadiau near Quinsaines, in 2007. Despite erosion, the excavation revealed a ditch and traces of two buildings. The ceramic assemblage and the stone tool industry, partly imported from Grand Pressigny, illustrate the contacts between the inhabitants and the cultural groups from Western-Central (Artenac) and Northern France (Gord). An unusual deposit of seventeen Grand Pressigny flint objects, discovered in the foundations of a small building, provides information about the redistribution process of such products and shows that the site probably functioned in collaboration with the G…

Sex-specific signatures of intrinsic hippocampal networks and regional integrity underlying cognitive status in multiple sclerosis

2021

Abstract The hippocampus is an anatomically compartmentalized structure embedded in highly wired networks that are essential for cognitive functions. The hippocampal vulnerability has been postulated in acute and chronic neuroinflammation in multiple sclerosis, while the patterns of occurring inflammation, neurodegeneration or compensation have not yet been described. Besides focal damage to hippocampal tissue, network disruption is an important contributor to cognitive decline in multiple sclerosis patients. We postulate sex-specific trajectories in hippocampal network reorganization and regional integrity and address their relationship to markers of neuroinflammation, cognitive/memory per…

Sexes in gynodioecious Geranium sylvaticum do not differ in their isotopic signature or photosynthetic capacity

2017

In gynodioecious plants, females are expected to produce more or better seeds than hermaphrodites in order to be maintained within the same population. Even though rarely measured, higher seed production can be achieved through differences in physiology. In this work, we measured sexual dimorphism in several physiological traits in the gynodioecious plant Geranium sylvaticum. Photosynthetic rate, stomatal conductance, transpiration rate, WUE and isotopic signatures were measured in plants growing in two habitats differing in light availability. Females have been reported to produce more seeds than hermaphrodites. However, we did not observe any significant difference in seed output between …
