La question traitée dans cet article porte sur le monde d’après la pandémie… Représente-t-elle un moment décisif qui va nous faire basculer vers une société plus responsable sur les plans sociaux et environnementaux ? De nouvelles habitudes et de nouveaux comportements responsables vont-ils se mettre en place de manière durable ? Pour répondre à ces enjeux, cet article mobilise des théories plurielles associées aux changements d’habitudes. Des préconisations s’adressant autant aux entreprises, qu’aux décideurs publics ou citoyens sont proposées pour dessiner les contours d’un après-Covid-19 socialement et écologiquement plus acceptable.
In a world where belief systems are constantly evolving, the number of people making a religious pilgrimage has skyrocketed. The Camino (Road) to Santiago (Saint James) de Compostela has been part of this general fervor. The present study looks at the dichotomy within this particular
pilgrimage between the sacred and the profane, applying a historical method toward this end. It will demonstrate that at each of the three periods used here as units of analysis (Middle Ages, Renaissance, and Postmodernity), the sacred and the profane have combined in specific ways around
the constructs of separation, encapsulation, and hybridization. This categorization justifies pilgrimages’ depiction as societal and commercial phenomena; shows that this particular, mythical pilgrimage has always been associated with markets and consumption behavior; and offers insights
into these elements’ development and operationalization in the marketing arena.
Wine is very often consumed with
a meal. However, although it is
well known to tasters that the taste of wine changes in the presence
of food, the influence of dietary lipids on wine astringency and bitterness
caused by grape tannins is not well established from a molecular point
of view. In this context, we investigated wine tannin–lipid
interactions by combining biophysical techniques to sensory analysis.
Nuclear magnetic resonance and optical and electron microscopy showed
an interaction between catechin, a majority component of grape tannins,
and lipid droplets from a phospholipid-stabilized oil-in-water emulsion,
characterized by (a) an increase in the droplet size in the presence
of catechin, (b) slowing of their size growth over time, and (c) an
increase in lipid dynamics in the droplet interfacial layer. Those
results were strengthened by sensory analysis, which demonstrated
that dietary oils decrease the perception of astringency of grape
tannin solutions. Our results highlight that dietary lipids are crucial
molecular agents impacting our sensory perception during wine consumption.
Cet article vise à présenter les contributions majeures de l’ouvrage collectif intitulé Les reconfigurationsde l’échange marchand : Tour d’horizon, enjeux et perspectives, publié aux Presses universitaires du Québec etdirigé par les professeurs Myriam Ertz, Julien Bousquet et Damien Hallegatte. D’après l’ensemble des collaborateurs de cet ouvrage, l’échange marchand est en mutation profonde. Cette métamorphose a résulté en quatre grandes évolutions : une conceptualisation revue de l’échange marchand, l’émergence de devisesd’échanges alternatives, la réactualisation du produit aux coeur d’échange reconfigurés, et la quête de sens dans la consommation. Si les causes de ces évolutions sont assez difficiles à isoler de manière précise, il n’endemeure pas moins que cette modification en profondeur de la manière dont fonctionne le marché résulte dela convergence de trois tendances lourdes : les évolutions technologiques, les évolutions socioculturelles, et lescontraintes économico-financières. Cet article résume ainsi les domaines de changement ainsi que les causesde changement tel qu’identifié par les auteurs de l’ouvrage collectif.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
