^aAfter careful consideration of some originally ordinal variables’ distribution and performances in the model, they have been converted into dichotomous variables, with value one when respondents judge the characteristics analysed being “important” or “extremely important” (original response equal to 4 or 5) and value zero to all other responses (original response from 1 to 3). The recoding allows emerging the behaviour of the respondent that give more importance to the specific characteristic; results do not notably change when considering the original responses as categorical variables
