Alfabetización en salud a través de las competencias
2019
En este trabajo se presenta una propuesta para la alfabetización en salud a través de la concreción y definición de las competencias que debe adquirir el alumnado durante la Educación Obligatoria. Mediante un estudio Delphi, se han determinado ocho ámbitos de salud, identificando los problemas o situaciones de salud que debe saber resolver el alumnado, así como las competencias que desarrollar y los contenidos de aprendizaje necesarios para afrontar cada uno de estos problemas. Estos contenidos de aprendizaje constituyen el instrumento de análisis con el que se ha revisado el currículo para comprobar en qué medida están presentes en las propuestas oficiales. Los estudios realizados referent…
Los museos etnológicos como instrumentos de formación ciudadana para la sostenibilidad
2008
La investigación que se presenta estudia el papel que los museos etnológicos pueden jugar en la educación científica para contribuir a sociedades más sostenibles, dado que dichos museos pretenden mostrar aspectos esenciales de la vida de los grupos humanos y las relaciones que se establecen entre ellos y el medio que les rodea. Pueden ser así un instrumento idóneo para abordar, tanto los problemas locales que afectan a un grupo humano concreto, como los globales a los que ha de hacer frente la humanidad. Se ha analizado en qué medida el contenido de los museos etnológicos incorpora la problemática socioambiental y, a la luz de dicho análisis, se han diseñado herramientas -entre ellas un mus…
Usability in ERP (Single and Multiple Document Interface) Application Environments
2014
The usability of complex information systems, like enterprise resource planning (ERP), is the next frontier, as the trend becomes more and more adopted in the industrial working environment. In complex information systems, the traditional usability criteria of learnability, effectiveness and efficiency have never lost their importance, even though the focus of research appears to have shifted for the consumer product. This study based on 110 responses attempt to highlight the usability issues in ERP single document interface (SDI) and multiple document interface (MDI) application environments. It also investigates the effect of negative user experience, such as ‘confusion’, on learnability,…
Multimodal Communication and Peer Interaction during Equation-Solving Sessions with and without Tangible Technologies
2023
Despite the increasing use of technologies in the classroom, there are concerns that technology-enhanced learning environments may hinder students’ communication and interaction. In this study, we investigated how tangible technologies can enhance students’ multimodal communication and interaction during equation-solving pair work compared to working without such technologies. A tangible app for learning equation solving was developed and tested in fourth and fifth-grade classrooms with two class teachers and 24 students. Video data of the interventions were analysed using deductive and inductive content analysis. Coded data were also quantified for quantitative analysis. Additionally, teac…
The use of barley straw residues to avoid high erosion and runoff rates on persimmon plantations in Eastern Spain under low frequency-high magnitude …
2016
[EN] Soil and water losses due to agricultural mismanagement are high and non-sustainable in many orchards. An experiment was set up with rainfall simulation at 78 mm h(-1) over 1 hour on 20 paired plots of 2 m(2) (bare and straw covered) in new persimmon plantations in Eastern Spain. Effects of straw cover on the control of soil and water losses were assessed. An addition of 60% straw cover (75 gm(-2)) resulted in delayed ponding and runoff generation and consequently reduced water losses from 60% to 13% of total rainfall. The straw cover reduced raindrop impact and thus sediment detachment from 1014 to 47 g plot(-1) h(-1). The erosion rate was reduced from 5.1 to 0.2 Mg ha-(1) h(-1). The …

Surface canal, squelette et espace des sphères
2016
A canal surface is the envelope of a one-parameter familly of oriented spheres. With the knowledge of center an radius functions associated to it, it is easy to compute a parametrisation of the surface. In this article, we study the inverse operation, which is the search for the spheres in the canal surface. By selecting a point on the boundary and using the sphere space, we estimate the maximal sphere tangent with this point and a second point on the boundary. Furthermore, we estimate a second sphere, which allows to build the characteiristic circle of the canal surface. So this article consists in a new approach of the skeletonization of an object. Indeed, a skeleton is a shape representa…

Euler Characteristics of Moduli Spaces of Curves
2005
Let ${mathcal M}_g^n$ be the moduli space of n-pointed Riemann surfaces of genus g. Denote by ${\bar {\mathcal M}}_g^n$ the Deligne-Mumford compactification of ${mathcal M}_g^n$. In the present paper, we calculate the orbifold and the ordinary Euler characteristic of ${\bar {\mathcal M}}_g^n$ for any g and n such that n>2-2g.
