Yes. I did not think to bring a definition with me. Dr. Richard Bourhis is a scholar from UQAM, l'Université du Québec à Montréal, who is one of our researcher-members. He was instrumental in creating the definition of “community vitality” some years ago. He would be interested, I'm sure, in discussing it with you.
There is also research I'd be happy to share with your committee.
