Competencias profesionales y empleo en el futuro periodista: el caso de los estudiantes de Periodismo de la Universidad Cardenal Herrera-CEU
2010
Presentamos un trabajo de investigacion cientifica enfocado en dos aspectos: la adquisicion de competencias profesionales en los alumnos de la licenciatura de Periodismo de la Universidad Cardenal Herrera-CEU y la importancia que otorgan a diferentes aspectos de un empleo. Este ultimo aspecto, partiendo del Informe Reflex de ANECA “El profesional flexible en la Sociedad del Conocimiento” establecemos una comparativa entre los resultados alli obtenidos y el caso particular de los alumnos de Periodismo de la Cardenal Herrera-CEU. Para descubrir estos aspectos presentamos un trabajo empirico para conocer en que medida los alumnos de ultimo curso de la licenciatura de la Universidad Cardenal He…
La competenza digitale dei futuri insegnanti della scuola primaria e dell’infanzia
2017
La sfida proveniente dall'identificazione della competenza digitale come una delle competenze-chiave di cittadinanza (EU, 2006), e in Italia, dal Piano Nazionale per la Scuola Digitale (2015), esige l’implementazione di percorsi educativo-didattici corredati da adeguati sistemi di valutazione; diventa pertanto imprescindibile promuovere interventi formativi specifici e fornire adeguati strumenti di valutazione e di autovalutazione ai futuri insegnanti di scuola primaria e dell’infanzia che li aiutino ad acquisire le competenze digitali necessarie per progettare percorsi di media education in ambito educativo. Il presente contributo mostra le fasi fondamentali del percorso di ricerca per lo …
Incremental Generalized Discriminative Common Vectors for Image Classification.
2015
Subspace-based methods have become popular due to their ability to appropriately represent complex data in such a way that both dimensionality is reduced and discriminativeness is enhanced. Several recent works have concentrated on the discriminative common vector (DCV) method and other closely related algorithms also based on the concept of null space. In this paper, we present a generalized incremental formulation of the DCV methods, which allows the update of a given model by considering the addition of new examples even from unseen classes. Having efficient incremental formulations of well-behaved batch algorithms allows us to conveniently adapt previously trained classifiers without th…
On the Online Classification of Data Streams Using Weak Estimators
2016
In this paper, we propose a novel online classifier for complex data streams which are generated from non-stationary stochastic properties. Instead of using a single training model and counters to keep important data statistics, the introduced online classifier scheme provides a real-time self-adjusting learning model. The learning model utilizes the multiplication-based update algorithm of the Stochastic Learning Weak Estimator (SLWE) at each time instant as a new labeled instance arrives. In this way, the data statistics are updated every time a new element is inserted, without requiring that we have to rebuild its model when changes occur in the data distributions. Finally, and most impo…
Day-ahead forecasting for photovoltaic power using artificial neural networks ensembles
2016
Solar photovoltaic plants power output forecasting using machine learning techniques can be of a great advantage to energy producers when they are implemented with day-ahead energy market data. In this work a model was developed using a supervised learning algorithm of multilayer perceptron feedforward artificial neural network to predict the next twenty-four hours (day-ahead) power of a solar facility using fetched weather forecast of the following day. Each set of tested network configuration was trained by the historical power output of the plant as a target. For each configuration, one hundred networks ensembles was averaged to give the ability to generalize a better forecast. The train…
Comportamentos de suporte e eficácia grupal: o papel mediador dos comportamentos de aprendizagem
2018
Dissertação de Mestrado em Psicologia do Trabalho, das Organizações e dos Recursos Humanos apresentada à Faculdade de Psicologia e de Ciências da Educação Supportive behaviours, defined “as the extent to which team members voluntarily provide assistance to each other when needed during task accomplishment” (Aubé & Rousseau, 2005, p.193), constitute a determinant of Team Effectiveness (Dimas, Rocha, Rebelo, & Lourenço, 2016). The current research aims to clarify further the relationship between Supportive Behaviours and Team Effectiveness criteria, mediated by Team Learning Behaviours. Based on the model of effectiveness Input-Mediator-Outcome-Input (IMOI) from Kozlowski and Ilgen (2006), th…
Towards more Valid Assessment of Learning from Animations
2020
Animated explanations have become an ubiquitous feature of modern educational practice. They provide a distinctive, non-verbal means of presenting information that is particularly appropriate for dynamic subject matter. However, the prevailing approaches used to assess learning from educational animations are almost exclusively verbal. There is thus a clear disconnect between the form of representation students encounter during their learning activity and the very different form of representation used to assess the resulting learning outcomes. This fundamental inconsistency undermines the validity of current assessment approaches and signals the need for a fresh look at how learning from an…
COMPREHENSIVE TEACHER’S PROFESSIONALISM FOR CONTENT AND LANGUAGE INTEGRATED PROVISION
2019
T opicality of the problem is determined by several factors as well as the amendments on the Education Law and the General Education Law, which provide for a gradual transition to the acquisition of general secondary education in Latvian only, educational content reform and teachers experience to work in an ethnically and linguistically heterogeneous environment. The aim of the study is to analyse comprehensive school teachers theoretical background and practice experience to work in the content and language integrated teaching and learning approach. Because language not a subject only but a mean of acquiring other subjects in the comprehensive school, too, all teachers need theoretical kno…
Perdió el libro que se compró / había comprado pocos días antes: Reflexiones iniciales en torno al saber gramatical sobre los tiempos verbales del pa…
2007
Carmen.Rdez-Gonzalo@uv.es La alternancia entre los tiempos verbales del pasado en textos escritos exige tener en cuenta diferencias aspectuales poco presentes en el español hablado. Según López García (2005: 162), el sistema de cinco tiempos simples (vengo, venía, vine, vendría, vendré) cubre las necesidades expresivas de los hispanohablantes, aunque los niños emplean menos y muchos hablantes adultos raramente usan otras formas. Los problemas se plantean cuando en lugar de hablar español necesitamos escribirlo y leerlo. Esta necesidad cambia por completo el inventario de tiempos ya que, para articular un texto es preciso dejar muy claro que unos acontecimientos ocurren antes o después de ot…
Local operators to detect regions of interest
1997
The performance of a visual system is strongly influenced by the information processing that is done in the early vision phase. The need exists to limit the computation on areas of interest to reduce the total amount of data and their redundancy. This paper describes a new method to drive the attention during the analysis of complex scenes. Two new local operators, based on the computation of local moments and symmetries, are combined to drive the selection. Experimental results on real data are also reported. © 1997 Elsevier Science B.V.
