Objectif: La prévalence de la consommation de cannabis chez les Inuits du Nunavik est l’une des plus élevées au monde, particulièrement chez les adolescents, et les facteurs permettant d’expliquer ce phénomène demeurent mal connus. Selon Bronfenbrenner (1979), la famille est l’unité la plus proximale de l’adolescent et est susceptible d’influencer particulièrement ses comportements. L’objectif de cette étude est d’examiner de manière longitudinale l’association entre la consommation de cannab...
This paper considers a dynamic scheduling problem where the set of jobs to perform is modified by the arrival of events (customer orders) requiring the execution of a new job or the cancellation of a previously ordered one once the production has begun. To tackle this dynamic context, we propose an online approach that reconsiders the actual schedule every time a new event arrives. In particular, upon an event arrival, the remaining unprocessed jobs as well as the new event are scheduled by a...
This paper describes the modeling efforts devoted by the Ministry of Health and Social Services of Québec, Canada (MSSS), to ensure the long-term bearability of their care system. To this end, it studies the relationships between four entities that self-regulate and interact to form the complex care-providing system: (1) universities; (2) hospitals and doctors; (3) the ministry; and (4) society. The first phase of this research focuses on modeling such relationships and relies on the system d...
This paper proposes an integrated approach to merge patient prioritization and patient schedulingto improve access to services in an elective (i.e., non-urgent) context. In particular, we assume thatpatients are included on a waiting list for a given surgery, and that every patient on the list hasreceived a ‘‘utility score’’, which is aproxyfor the relative urgency with regards to the other patientson the list. A mathematical model is formulated to solve the patient scheduling problem, i.e., ...
