A modelling framework based on MDP to coordinate farmers' disease control decisions at a regional scale.

The effectiveness of infectious disease control depends on the ability of health managers to act in a coordinated way. However, with regards to non-notifiable animal diseases, farmers individually decide whether or not to implement control measures, leading to positive and negative externalities for connected farms and possibly impairing disease control at a regional scale. Our objective was to facilitate the identification of optimal incentive schemes at a collective level, adaptive to the epidemiological situation, and minimizing the economic costs due to a disease and its control.

Transcultural validation of the SIGAM mobility grades in French: The SIGAM-Fr.

Background: The main French language scales evaluating functioning after lower-limb amputation have not undergone exhaustive psychometric validation.

Objective: A transcultural validation of the Special Interest Group in Amputee Medicine (SIGAM) mobility grades questionnaire, with 21 closed questions, as an administered questionnaire.

Methods: The questionnaire translation, back-translation and original-author validation was followed by a pretest with 5 patients to check comprehension.

Modelling collective effectiveness of voluntary vaccination with and without incentives.

Control strategies of infectious diseases at a regional level can rely on vaccination. When the decision to vaccinate is made by each farmer on a voluntary basis, a farmer vaccinates to protect his own herd. If the vaccinated herds are protected against infection, the risk for other herds is reduced, creating a positive externality (i.
