Résumé
Les auteurs exposent les composantes d'un modèle de recherche collaborative lié à une certaine façon de faire de la recherche «avec» plutôt que «sur» les praticiens. C'est sous l'angle de la double fonction de recherche et de formation, à concilier dans la démarche collaborative, que leur modèle est abordé. Le texte situe historiquement l'émergence de l'idée de collaboration de recherche en éducation et présente les trois facettes complémentaires du modèle: a) une définition conceptuelle du modèle conduit à préciser le sens donné aux notions de recherche et de formation; b) le modèle est illustré par une description de cinq projets différents basés sur une démarche collaborative commune; c) une lecture transversale des cinq projets conduit à discuter des composantes du modèle.
Accuracy of forensic facial approximation and superimposition techniques relies on the knowledge of anatomical correlations between soft and hard tissues. Recent studies by Stephan and collaborators (6,8,10) reviewed traditional guidelines leading to a wrong placement of the eyeball in the orbit. As those statements are based on a small cadaver sample, we propose a validation of these findings on a large database (n = 375) of living people. Computed tomography scans of known age and sex subjects were used to collect landmarks on three-dimensional surfaces and DICOM with TIVMI. Results confirmed a more superior and lateral position of the eyeball relatively to the orbital rims. Orbital height and breadth were used to compute regression formulae and proportional placement using percentages to find the most probable position of the eyeball in the orbit. A size-related sexual dimorphism was present but did not impact on the prediction accuracy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
