Explorer par la carte l’espace pendant le confinement: Une expérimentation de cartographie sensible

National audienceThis article describes an experiment of sensitive mapping, targeting space as lived and perceived in France during the first lockdown due to Covid-19. Maps were created by the participants of the sensitive mapping seminar led by the French school of higher studies in social sciences (EHESS in French). Analysing these maps highlighted different spatial, temporal, perceptive, or emotional landmarks, which are either individual or shared. The maps show the tightening in and around housing, in a spatial environment marked by new rules of accessibility. Space was explored in new ways and space uses were both reorganised and relocated. Sensitive mapping offers a methodological framework for the individual expression of one’s own relation to space, itself modified by the lockdown.Cet article présente une expérimentation de cartographie sensible visant à documenter l’espace de vie tel que vécu et perçu pendant le premier confinement dû à la Covid-19. L’analyse des cartes réalisées par les participants du séminaire de cartographie sensible de l’École des hautes études en sciences sociales (EHESS) a mis en évidence des repères spatiaux, temporels, perceptifs, émotionnels qui sont personnels ou partagés. Les cartes montrent le resserrement dans et autour du logement, dans un environnement qualifié par une nouvelle accessibilité. L’espace a été exploré de manière inédite et les usages se sont adaptés et relocalisés. La cartographie sensible offre un cadre méthodologique, qui a permis l’expression individuelle du rapport à l’espace, lui-même modifié par le confinement

Lived and perceived space during lock-down in a sensitive map approach

International audienceThe first lock-down in France due to the Covid-19 pandemic happened during spring 2020. It meant restrictions for everyone regarding reachable space and possible time length outside home. The seminar of sensitive mapping taking place in École des hautes études en sciences sociales (EHESS) went online and proposed an exercise to investigate the consequences of these statutory restrictions on individual lived and perceived space. The defined protocol of the exercise was based on the framework of the sensitive map approach. This approach adapts the principles of conventional cartography so that to favour personal information selection and design. Each participant of the seminar had the task to map their space. Displayed information should concern meaningful elements from their spatial environment. Other targeted information was sensitive information including emotions, feelings, and opinions as well as perceived elements from the five senses. The resulted map corpus offers diverse mapping creations. Each map contains several graphic items. Items are mainly cartographical displays enriched with non-cartographical drawings, pictures, photos, records, charts. Techniques were mixed: pen, fabrics, computer-based. The themes of displayed elements are about spatially-stable features like the dwelling, buildings remained open, green spaces, and about ephemeral and sensitive information like social interactions, people, perceived sounds, smells and feelings about the lock-down situation and the pandemic. Some maps have used or were inspired by topographic maps. Though in most maps, distances and topology are subjective. Sensitive mapping appeared as an interesting approach to collect individual testimonies and might be complementary to statistical studies

Panel of sensitive mapping experiments with respect to various sources of information

International audienceSensitive mapping corresponds to a process of making maps by consciously integrating personal subjectivity about a space during observation and visualization. The approach is mobilized to express emotions, sentiments and opinions associated to a spatial environment as well as a mean to be attentive to this environment based on the five senses. The objective of the work is to explore the relations between sources of information about a space and resulted maps. Three sensitive mapping experiments implemented during the seminar in sensitive mapping in École des hautes études en sciences sociales (EHESS) are described. Different sources are used: direct observation, audio records and texts. The maps made by the participants were analyzed according to the criteria of the chosen material, the conceptualization of space, the scale and extent, the selection and display of information. Specificities and similarities between maps helped formulating hypotheses about the role of map-makers and the apprehension of space depending on the sources. Direct observation implied that the map-maker is physically in a space. Subjectivity can be seen on the maps through little completeness of the landscape features and display of emotions, sentiments and opinions. Audio records and texts implied that the map-makers did not go into the space. Maps contain relative completeness and details of information from the sources, mainly regarding landscape features. Interpretations by map-makers appeared more in the design than in the information selection. Sources of information can thus be considered complementary and sensitive mapping experiments can combine them to gather knowledge and perceptions about a space

Association between location of out-of-hospital cardiac arrest, on-scene socioeconomic status, and accessibility to public automated defibrillators in two large metropolitan areas in Canada and France

International audienceAimTo compare walking access times to automated external defibrillators (AEDs) between area-level quintiles of socioeconomic status (SES) in out-of-hospital cardiac arrest (OHCA) cases occurring in 2 major urban regions of Canada and France.MethodsThis was an international, multicenter, retrospective cohort study of adult, non-traumatic OHCA cases in the metropolitan Vancouver (Canada) and Rhône County (France) regions that occurred between 2014 and 2018. We calculated area-level SES for each case, using quintiles of country-specific scores (Q5=most deprived). We identified AED locations from local registries. The primary outcome was the simulated walking time from the OHCA location to the closest AED (continuous and dichotomized by a 3-minute 1-way threshold). We fit multivariate models to analyze the association between OHCA-to-AED walking time and outcomes (Q5 vs. others).ResultsA total of 6,187 and 3,239 cases were included from the Metro Vancouver and Rhône County areas, respectively. In Metro Vancouver Q5 areas (vs. Q1-Q4), areas, AEDs were farther from (79% over 400m from case vs. 67%, p<0.001) and required longer walking times to (97% above 3min vs. 91%, p<0.001) cases. In Rhône Q5 areas, AEDs were closer than in other areas (43% over 400m from case vs. 50%, p=0.01), yet similarly poorly accessible (85% above 3min vs. 86%, p=0.79). In multivariate models, AED access time ≥ 3min was associated with decreased odds of survival at hospital discharge in Metro Vancouver (odds ratio 0.41, 95% CI [0.23-0.74], p=0.003).ConclusionsAccessibility of public AEDs was globally poor in Metro Vancouver and Rhône, and even poorer in Metro Vancouver’s socioeconomically deprived areas
