He focuses notably upon philosophical and ethical questions raised by new digital technologies (big data, artificial intelligence, robots …). He also coordinates NHNAI international research program focused upon the exploration of the idea of “Humanism” in the time of Neurosciences and AI.In Study 1, institutions (N=10) with multidisciplinary teams (N=87) were included. Following the training, a focus group was conducted to gather perceptions about the adoption of new behaviours. Using thematic analysis, the NVivo software was employed. All participants reported gains (personal, relational, and/or in terms of caring for older adults); it is important to highlight the discovery of Serious Leisure as “an absolute novelty”; Serious Leisure proved effective as a tool for promoting IHD, among other outcomes.
