De l'orientation en fin de cinquième au fonctionnement du collège
1988
Analyse des mécanismes de l'orientation à l'issue de la classe de cinquième, à partir d'une enquête dans 17 collèges de l'Académie de Dijon, représentant 2350 élèves, scolarisés en 1982/1983. Étude de l'impact des caractéristiques socio-démographiques des élèves sur l'orientation à l'issue de la 5ème ; analyse des interactions entre les différents acteurs engagés dans le processus de l'orientation. Analyse de la variété des pratiques d'un collège à l'autre.
Preclinical models for colonic absorption, application to controlled release formulation development.
2018
Oral controlled release (CR) formulations have many benefits and have become a valuable resource for the local and systemic administration of drugs. The most important characteristic of these pharmaceutical products is that drug absorption occurs mainly in the colon. Therefore, this review analyses the physiological and physicochemical features that may affect an orally administered CR product, as well as the different strategies to develop a CR dosage form and the methods used to evaluate the formulation efficacy. The models available to study the intestinal permeability and their applicability to colonic permeability determinations are also discussed.
Towards Vorst's conjecture in positive characteristic
2018
Vorst's conjecture relates the regularity of a ring with the $\mathbb{A}^1$-homotopy invariance of its $K$-theory. We show a variant of this conjecture in positive characteristic.
Equidistribution and Counting of Rational Points in Completed Function Fields
2019
Let K be a (global) function field over Fq of genus g, let v be a (normalised discrete) valuation of K, let Kv be the associated completion of K, and let Rv be the affine function ring associated with v.
[RIU project: perceived changes by health agents and professionals after a health intervention in an urban area of socioeconomic disadvantage].
2013
Resumen Objetivo Describir los cambios percibidos por la población y los profesionales en relación con la salud y el uso de servicios tras la intervención RIU con agentes comunitarios en un barrio vulnerable. Diseño Estudio descriptivo cualitativo con entrevistas individuales y grupales y observación participante de octubre de 2008 a julio de 2009. Emplazamiento Barrio Raval (Algemesí-Valencia). Participantes Selección por muestreo opinático de 7 mujeres agentes de salud, todas las que finalizaron la intervención, y 10 profesionales implicados en la misma. Método Con las mujeres se mantuvo una entrevista grupal a los 6 meses, y una entrevista grupal y 7 individuales a los 9 meses de interve…
The media competence as a challenge for educommunication : tools of evaluation
2014
RESUMEN: Para mejorar el aprendizaje, los avances tecnológicos ponen a disposición de los agentes educativos recursos emergentes, los cuales requieren del desarrollo de competencias o destrezas básicas por parte de los estudiantes y suponen un reto para toda la comunidad educativa. En este contexto, la competencia mediática se convierte en la clave para fomentar un uso responsable, eficiente y democrático de los recursos mediáticos por parte de los ciudadanos. Se presentan aquí los resultados de un proyecto de investigación realizado en España, en el que se han diseñado diversos instrumentos de evaluación de la competencia mediática de estudiantes, profesorado, así como de padres y madres. …
¿Son las TIC un factor clave en la adquisición de competencias? Un análisis con evaluaciones por ordenador
2015
Este artículo analiza los efectos de la tenencia y uso de las tecnologías de la información y la comunicación (TIc) en la adquisición de competencias (evaluadas por ordenador en la prueba de PIsa de 2012). los principales resultados son los siguientes. En primer lugar, se constata que las variables TIc inciden en mayor medida en la adquisición de matemáticas que en el resto de competencias evaluadas (comprensión lectora y ciencias). En segundo lugar, resulta relevante la variable TIc utilizada, ya que no todas inciden del mismo modo. Finalmente, existen algunos resultados dispares por género.
Isometric endurance test of the cervical flexor muscles - Reliability and normative reference values.
2017
Abstract Objective To obtain reference values for the isometric endurance test (IET) of the cervical flexor muscles, investigate its reproducibility, and compare the results with the maximal isometric strength test (MIST) of the cervical flexor muscles. Design Cross-sectional non-comparative study with single group repeated measurements. Methods Altogether 219 healthy females aged 20–59 years volunteered to participate in the study. The IET was performed in the supine position and MIST seated. The reproducibility was evaluated by the intraclass correlation coefficient (ICC) and an analysis described by Bland and Altman. The relationship between the two measuring methods was evaluated by Pea…
Approximated overlap error for the evaluation of feature descriptors on 3D scenes
2013
This paper presents a new framework to evaluate feature descriptors on 3D datasets. The proposed method employs the approximated overlap error in order to conform with the reference planar evaluation case of the Oxford dataset based on the overlap error. The method takes into account not only the keypoint centre but also the feature shape and it does not require complex data setups, depth maps or an accurate camera calibration. Only a ground-truth fundamental matrix should be computed, so that the dataset can be freely extended by adding further images. The proposed approach is robust to false positives occurring in the evaluation process, which do not introduce any relevant changes in the …
A grid representation for distributed virtual environments
2004
Fast Internet connections and the widespread use of high performance graphic cards are making Distributed Virtual Environments (DVE) very common nowadays. The architecture and behavior of these systems are very similar to new grid computing applications where concepts such as sharing and high scalability are extremely exploited. However, there are several key issues in these systems that should still be improved in order to design a scalable and cost-effective DVE system. One of these key issues is the partitioning problem. This problem consists of efficiently assigning clients (3-D avatars) to the arbiters (servers) in the system. As an alternative to the ad-hoc heuristic proposed in the l…
