Parental Competence in Infant and Primary Education: design and validation of an instrument
2021
Actualmente, la familia se encuentra ante retos que requieren de su eficiencia y eficacia en la crianza, protección y orientación de los hijos, es decir, la parentalidad y la capacidad de los padres de ejercerla de forma competente. Desde este punto de vista, destaca la necesidad de un modelo educativo centrado en el desarrollo de las competencias parentales que proporcione conocimientos, habilidades y actitudes que optimicen el rol parental respecto al desarrollo pleno y sistémico del ser humano. Ante la necesidad de conocer si los padres asumen de forma óptima su papel en la educación de sus hijos, se plantea como objetivo principal de este artículo el diseño de un instrumento para el aná…
Forest nurseries and the National Recovery and Resilience Plan: the case of Sicily and Apulia (Italy)
2023
In Italy, the National Recovery and Resilience Plan (NRRP) foresees the planting of ca. 6.6 million trees to establish urban and peri-urban forests in 14 metropolitan cities. This ambitious project requires a significant number of native trees and shrubs, currently unavailable in Italian public and private nurseries. This survey analyzes the state of forest nurseries in two administrative regions of southern Italy, i.e. the “Filici” forest nursery (province of Agrigento, Sicily) and the Gargano Mountain Reclamation Consortium (province of Foggia, Apulia), to evaluate the adequacy of Sicilian and Apulian forest nurseries as potential sources of plant material to meet the requirements of the …
La influencia del estado del partido en la posesión del balón en el fútbol femenino de alto rendimiento
2020
[Abstract] The objective of this study was to examine the effect of the situational match status variable on the ball possession of the teams that participated in the 2015 FIFA Women’s World Cup. The 52 games played during the championship have been collected, and 3,740 ball possessions made by the teams were analyzed. The teams have been divided into successful and unsuccessful. Three types of analysis have been carried out: a univariate analysis for both groups with the categorical and continuous variables selected; a bivariate analysis, using chi-square tests and the exact Fischer test; and finally, a multivariable technique such as the decision trees was incorporated. The available resu…
Entre natros i mosatros: representacions socials, discursos agraris i discursos mediambientals al Delta de l'Ebre i l'Albufera de València
2015
Des de les últimes dècades del segle passat els treballs empírics constaten que els límits naturals al creixement (Meadows et al., 1972) han sigut traspassats (Garcia, 2004). Això ha suposat un increment de la consciència mediambiental i ha donat lloc a la recerca de respostes de diferents tipus. Moltes d’aquestes respostes estan emmarcades dintre de les polítiques neoliberals que concilien desenvolupament econòmic i sostenibilitat i, d’aquesta manera, neguen el conflicte ecològic. Entre aquestes solucions està l’establiment de determinats espais en els que es pretén preservar la naturalesa: els Parcs Naturals en són una mostra. En la seua versió neoliberal, l’esmentada preservació no impli…
Intelligent solutions for real-life data-driven applications
2017
The subject of this thesis belongs to the topic of machine learning or, specifically, to the development of advanced methods for regression analysis, clustering, and anomaly detection. Industry is constantly seeking improved production practices and minimized production time and costs. In connection to this, several industrial case studies are presented in which mathematical models for predicting paper quality were proposed. The most important variables for the prediction models are selected based on information-theoretic measures and regression trees approach. The rest of the original papers are devoted to unsupervised machine learning. The main focus is developing advanced spectral cluster…
Pd2Au36(SR)(24) cluster: structure studies
2015
The location of the Pd atoms in Pd2Au36(SC2H4Ph)(24), is studied both experimentally and theoretically. X-ray photoelectron spectroscopy (XPS) indicates oxidized Pd atoms. Palladium K-edge extended X-ray absorption fine-structure (EXAFS) data clearly show Pd-S bonds, which is supported by far infrared spectroscopy and by comparing theoretical EXAFS spectra in R space and circular dichroism spectra of the staple, surface and core doped structures with experimental spectra.
Behind the scenes of artificial intelligence: a study of micro-work platforms in France
2019
Este artículo es una versión resumida del informe “Le Micro-travail en France. Derrière l’automatisation de nouvelles précarités au travail?» This article is a summarized version of the report "Le Micro-travail en France. Derrière l’automatisation de nouvelles précarités au travail?" .; International audience; Micro-work internet services allocate small, standardized tasks of data generation and annotation to crowds of providers. The outputs are mainly used to produce artificial intelligence solutions. It is an exemplary instance of the “platformization” of the economy, and of the transformations of labour that digital technologies bring about. To uncover the conditions under which micro-wo…
Spatially dynamic forest management to sustain biodiversity and economic returns.
2014
Production of marketed commodities and protection of biodiversity in natural systems often conflict and thus the continuously expanding human needs for more goods and benefits from global ecosystems urgently calls for strategies to resolve this conflict. In this paper, we addressed what is the potential of a forest landscape to simultaneously produce habitats for species and economic returns, and how the conflict between habitat availability and timber production varies among taxa. Secondly, we aimed at revealing an optimal combination of management regimes that maximizes habitat availability for given levels of economic returns. We used multi-objective optimization tools to analyze data fr…
Efficient Time Integration of Maxwell's Equations with Generalized Finite Differences
2015
We consider the computationally efficient time integration of Maxwell’s equations using discrete exterior calculus (DEC) as the computational framework. With the theory of DEC, we associate the degrees of freedom of the electric and magnetic fields with primal and dual mesh structures, respectively. We concentrate on mesh constructions that imitate the geometry of the close packing in crystal lattices that is typical of elemental metals and intermetallic compounds. This class of computational grids has not been used previously in electromagnetics. For the simulation of wave propagation driven by time-harmonic source terms, we provide an optimized Hodge operator and a novel time discretizati…
Innoeduca : international journal of technology and educational innovation
2021
En una sociedad cada vez más digital, la escuela está llamada a cumplir una responsabilidad fundamental en el desarrollo de la destreza tecnológica de los estudiantes de cualquier etapa educativa. El papel del docente es, por tanto, un factor clave para el desarrollo de la competencia digital, especialmente, en las primeras edades. En este sentido, este artículo pretende analizar, mediante una revisión normativa y bibliográfica, cómo se ha ido integrando la tecnología en nuestro sistema educativo y qué importancia ha tenido la formación tecnológica del profesorado en los últimos años. Asimismo, se revisan diferentes propuestas de marcos de competencia digital docente, a fin de poder contrap…
