Reliability and validity of the Finnish version of the Lower Extremity Functional Scale (LEFS)
2017
The present study aimed to assess the psychometric properties of the Finnish version of the Lower Extremity Functional Scale (LEFS) among foot and ankle patients.The LEFS was translated and cross-culturally adapted to Finnish. We assessed the test-retest reliability, internal consistency, floor-ceiling effect, construct validity and criterion validity in patients who underwent surgery due to musculoskeletal pathology of the foot and ankle (N = 166).The test-retest reliability was high (ICC = 0.93, 95% CI: 0.91-0.95). The standard error of measurement was 4.1 points. The Finnish LEFS showed high internal consistency (Cronbach's α = 0.96). A slight ceiling effect occurred as 17% achieved the …
Linear quotients of Artinian Weak Lefschetz algebras
2013
Abstract We study the Hilbert function and the graded Betti numbers for “generic” linear quotients of Artinian standard graded algebras, especially in the case of Weak Lefschetz algebras. Moreover, we investigate a particular property of Weak Lefschetz algebras, the Betti Weak Lefschetz Property, which makes possible to completely determine the graded Betti numbers of a generic linear quotient of such algebras.
Remarks on the relations between the Italian and American schools of algebraic geometry in the first decades of the 20th century
2004
Abstract In this paper we give an overview of the interactions between Italian and American algebraic geometers during the first decades of the 20th century. We focus on three mathematicians—Julian L. Coolidge, Solomon Lefschetz, and Oscar Zariski—whose relations with the Italian school were quite intense. More generally, we discuss the importance of this influence in the development of algebraic geometry in the first half of the 20th century.
Assessment of the structural validity of three foot and ankle specific patient-reported outcome measures
2020
Background: The structural validity of the Lower extremity functional scale (LEFS), the Visual analogue scale foot and ankle (VAS-FA), and the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) has not been compared earlier in patients after foot and ankle surgery. Methods: Altogether 165 previously operated patients completed the foot and ankle specific instruments, the 15D health-related quality of life (HRQoL) instrument, and general health (VAS). Results: The LEFS, the VAS-FA and the WOMAC had slight differences in their measurement properties. The VAS-FA had the best targeting and coverage. All three foot and ankle measures accounted for mobility and usual activitie…
Validation of the Western Ontario and McMaster Universities Osteoarthritis Index in Patients Having Undergone Ankle Fracture Surgery
2019
The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) is a patient-reported outcome measure (PROM) that is widely used to evaluate the pain, stiffness, and physical function of patients with osteoarthritis of the hip and knee. Although the WOMAC has also been used for patients after foot and ankle surgery, it has not been validated for this purpose. A total of 130 patients with surgically treated ankle fractures completed the WOMAC, Visual Analogue Scale Foot and Ankle (VAS FA), Lower Extremity Functional Scale (LEFS), 15D Health-Related Quality-of-Life Questionnaire (15D), and Visual Analog Scale for General Health (VAS general health) after foot and ankle surgery. The…
SIX NUANCES D'A-GREY-GATION L'influence du choix des unités spatiales d'agrégation sur la lecture et l'interprétation des résultats cartographiés
2017
National audience; En même temps que les activités humaines se sont informatisées, les sources de données géographiques se sont diversifiées, autant du point de vue de leur production (smartphones, capteurs, simulation) que de leur gestion (modélisation, base de données et protocoles d’interrogation). Ces données de « nouvelle génération » partagent en général le fait d’être massives, désagrégées et multidimensionnelles. Elles se caractérisent par des attributs riches d’un point de vue spatial (localisation), thématique (type d’activité) et temporel (heure de début et de fin, durée). En contrepartie, leur volume et leur structure les rendent difficilesà manipuler (Batty, 2013 ; Kitchin, 201…
Linked data vocabularies for BIM
2019
Given the high interest in the field of BIM (Building Information Modeling) for Linked Data approaches over the last years, the article at hand presents an evaluation of the main Linked Data vocabularies available for the considered domain. First, Semantic Web layer architecture is presented, along with the 4 main principles of Linked Data. Second, each vocabulary is evaluated according to these 4 principles, while 2 additional ones are added in order to assess the licence associated with the vocabulary (open or not, specified or missing). An overall comparison among the considered vocabularies is also provided, thus helping in choosing which vocabulary to use in future Linked Data applicat…
Méthodes d'acquisition, de codage et d'analyse de profils sensoriels temporels
2004
National audience; La méthode de Temps-Intensité (TI) consiste à mesurer l’évolution de la perception de l’intensité d’un descripteur au fil du temps de la dégustation d’un produit. Lorsque plusieurs descripteurs sont étudiés (situation du profil sensoriel), cette méthode devient quasiment impraticable car elle nécessite une dégustation par descripteur. Cette communication se propose de synthétiser un ensemble de travaux visant à proposer des méthodes d’obtention de courbes des évolutions temporelles de plusieurs descripteurs simultanément. La première de ces méthodes, Dominance Temporelle des Sensations (DTS) [1], a permis de restituer assez fidèlement les courbes TI de 10 descripteurs pou…
