PRACTICE HUNTING: Time Use Surveys for a quantification of practices distributions and evolutions
2 likes1,158 views
The document examines the patterns and meanings of eating practices in France and the UK, highlighting how cultural differences, time constraints, and social factors influence meal timings and compositions. It presents data on meal consumption and associated electricity demands, aiming to understand the relationship between household activities and energy use. Key findings suggest variations in the significance of skipping dinner between the two countries, with implications for energy consumption and social practices.

- 13. Conclusion ● Meanings : Traces of commensality : participants, longer and later dinner, competition with TV Eating out (as defined) has different meanings in France : sharing with friends UK : convenient/efficient nutrition (no later or longer meal, surrounded with much more typical home activity)
- 14. Conclusion Skipping dinner (as defined) has different meaning in: France: work in the evening, dinner pushed before or after UK: no dinner at all, replaced by social life Economy of time Clear competition between work and different time intensive eating practices
- 15. Conclusion ● Material : Little information at the activity level: place, transport mode More information at the individual/household level Need to link with dedicated surveys associating diaries with appliance usage : high difficulty ● Competences : Directly related to individuals
- 16. Next steps ● Direct link between activities and related appliance usage and electricity consumption ● Hunting practices in the past TUS waves (10 years) to identify how practices spread, shrink or change Limits ● Lack of direct information on meanings and devices ● Two days not enough to identify patterns and regularity ● Not so different from usual descriptive analyses

- 18. Eating practices in TUS ● General description of eating practices ● France (De Saint-Pol et al. 2013): 3 meals structure, work/meal constraints, reception/TV relation to social satus, younger snacking… ● International comparisons: differences in the times and places of meals in relation with cultural aspects, work organisation and specific infrastructures… ● Looking for meanings: relation to the organisation of time, comensality, duty, satisfaction (Daniels et al. 2012)
