Recherche d'information sur Internet et expérience de consultation
2001
International audience; Le propos de cet article est de caractériser, sur un plan théorique, la nature de l'expérience vécue par le consommateur lors de la consultation d'Internet, de façon à trouver le meilleur design d'un site commercial. Il compare l'expérience de consultation vécue selon que l'objectif initial poursuivi par l'utilisateur est la distraction ou la recherche d'information. Il examine les sources de gratifications et de frustrations contribuant à la valorisation de cette expérience.
Individual and shared digital repertoires : older adults managing digital services
2023
The rise of public and other non-recreational digital services is based on the idea of catering to the daily needs of the citizens cost-efficiently and with ease. Previous research has approached the use of digital services mainly from the perspective of an individual, while the significance of shared practices of use has attracted only a little attention. In this article, we (1) examine the incentives and limitations associated with the use of non-recreational digital services, which either encourage or discourage older adults to use them. Based on the first question, we then ask (2) how older adults in this study manage those non-recreational digital services they have chosen to use. Our …
Ethnic differences in utilization of online health information sources : A test of the social inequality hypotheses
2023
The goal of the current study was to understand ethnic differences in use of online health information sources. Social stratification and social diversification hypotheses were used as study’s theoretical framework. The data were obtained from the 2017 Israel Social Survey (N = 2166). Multinomial and logistic regression techniques were used for the multivariate analysis. The results suggest that Israeli Arab respondents were less likely than Israeli-born Jewish respondents to seek health information using the Health Funds’ call centers or websites, other websites, and to utilize any number of the online health information sources. The findings provide a strong support for the social strati…
Social and satisfied? : Social uses of mobile phone and subjective wellbeing in later life
2022
The current study examined the associations between socio-demographic background and engagement in social uses of mobile phone, and between the engagement in these uses and life satisfaction and health satisfaction in later life through the lens of digital divide and uses and gratifications theories. The data, collected from the retired Internet users (62 and older) residing in seven countries (N = 5713), were analyzed using logistic and linear regression models. The results show that education and age predicted the engagement in social uses in the most consistent way. A number of social uses positively related to both life and health satisfaction. Of the particular uses, e-mailing and inst…

The case for strategic international alliances to harness nutritional genomics for public and personal health
2005
Nutrigenomics is the study of how constituents of the diet interact with genes, and their products, to alter phenotype and, conversely, how genes and their products metabolise these constituents into nutrients, antinutrients, and bioactive compounds. Results from molecular and genetic epidemiological studies indicate that dietary unbalance can alter gene-nutrient interactions in ways that increase the risk of developing chronic disease. The interplay of human genetic variation and environmental factors will make identifying causative genes and nutrients a formidable, but not intractable, challenge. We provide specific recommendations for how to best meet this challenge and discuss the need …
Stratification Dynamics in Drying Colloidal Mixtures
2017
Stratification in binary colloidal mixtures was investigated using implicit-solvent molecular dynamics simulations. For large particle size ratios and film Péclet numbers greater than unity, smaller colloids migrated to the top of the film, while big colloids were pushed to the bottom, creating an "inverted" stratification. This peculiar behavior was observed in recent simulations and experiments conducted by Fortini et al. [ Phys. Rev. Lett. 2016 , 116 , 118301 ]. To rationalize this behavior, particle size ratios and drying rates spanning qualitatively different Péclet number regimes were systematically studied, and the dynamics of the inverted stratification were quantified in detail. Th…
The Rhetoric of Healthcare Inequality in Capitalist Classed Societies: Blomkamp’s and Romanek’s Dystopian Visions
2018
The future of democratic societies has been widely debated among futurologists, including the possible ways medicine could advance, changing the lives of individuals and communities. Yet, what seems a reasonable question to ask is – how the unequal access to healthcare might perpetuate social and economic divisions and turn democracy into tyranny. This paper advances a rhetorical analysis of the reciprocal relations between healthcare and the classed capitalist system as portrayed in two dystopian pictures: Mark Romanek’s Never Let Me Go (2010) and Neill Blomkamp’s Elysium (2013). The realities depicted in these movies, as well as their narratives, vary considerably; however, they both pres…
Hjelmslev et la "fonction sémiotique", du modèle structural au modèle cognitif
2008
The article discusses the concept of semiotics function in Hjelmslev, finding sources of the theory of language’s stratification. The semiotic function, which is in Hjelmslev the principle underlying the dynamic layering, is identified here as both an attraction of two heterogeneous spaces and as a set of operations of sense’s establishment. At historiographic level, this article presents a new hypothesis of interpretation, that the hjelmslevian structuralism has not built a static theory of language, disinterested to the cognitive dimension, but a careful theory to operational aspects of semiosis.
