La voz como instrumento clave en la competencia comunicativa del docente universitario
2019
Actualmente, el perfil del profesor universitario engloba el desarrollo de competencias en áreas tan diferentes como complementarias: la docencia, la investigación y la gestión. En este trabajo se presenta una aproximación teórica al estado del arte respecto a las competencias del profesorado universitario en cuanto a su actuación docente. En concreto, se aborda la competencia comunicativa entendida como: a) la capacidad de formar enunciados que no solo sean gramaticalmente correctos sino también socialmente apropiados (Hymes, 1971) y b) el conjunto de conocimientos y destrezas/habilidades lingüísticas, discursivas, socioculturales que permiten la actuación eficaz y adecuada del hablante en…
Practice and assessment of oral skills in developing online preparatory materials through the InGenio authoring shell
2012
The practice of oral skills is a basic requirement of learning or teaching a new language, as one of the main goals in the field of language learning is developing oral communicative competence, especially needed in contexts where the students¿ L2 is the vehicular language and therefore the main means of interaction. The InGenio online authoring tool allows designers of new materials, as well as language teachers and students, to rethink and imagine new ways of dealing with practice and assessment of listening and speaking skills thanks to the flexibility of its templates, resources and tools. This article explores the ways in which the InGenio utilities, solutions and learning materials ar…
Ownership protection of plenoptic images by robust and reversible watermarking
2018
Abstract Plenoptic images are highly demanded for 3D representation of broad scenes. Contrary to the images captured by conventional cameras, plenoptic images carry a considerable amount of angular information, which is very appealing for 3D reconstruction and display of the scene. Plenoptic images are gaining increasing importance in areas like medical imaging, manufacturing control, metrology, or even entertainment business. Thus, the adaptation and refinement of watermarking techniques to plenoptic images is a matter of raising interest. In this paper a new method for plenoptic image watermarking is proposed. A secret key is used to specify the location of logo insertion. Employing discr…
Autonomous Demand Side Management of Electric Vehicles in a Distribution Grid
2019
The electricity demand due to the increasing number of EVs presents new challenges for the operation of the electricity network, especially for the distribution grids. The existing grid infrastructure may not be sufficient to meet the new demands imposed by the integration of EVs. Thus, EV charging may possibly lead to reliability and stability issues, especially during the peak demand periods. Demand side management (DSM) is a potential and promising approach for mitigation of the resulting impacts. In this work, we developed an autonomous DSM strategy for optimal charging of EVs to minimize the charging cost and we conducted a simulation study to evaluate the impacts to the grid operation…
Students’ Redesign of Mandatory Assignments in Teacher Education
2017
This article explores specific aspects of literacy practices in teacher education in Norway, building upon data collected within the research project Digital literacy and use of learning resources in teacher education in Norway (DigiGLU). Our main aim is to explore how teachers in different subject courses in teacher education (TE) design mandatory assignments, and how students respond to these designs. After the extensive TE-reform in 2010, in revised plans and documents guiding professional training, mandatory assignments (both form and content) were considered more important for the students’ learning process. In our investigation, the concepts of design for learning and design in learni…
The indexing of persons in news sequences using audio-visual data
2004
We describe a video indexing system that automatically searches for a specific person in a news sequence. The proposed approach combines audio and video confidence values extracted from speaker and face recognition analysis. The system also incorporates a shot selection module that seeks for anchors, where the person on the scene is likely speaking. The system has been extensively tested on several news sequences with very good recognition rates.
Non-specific bronchial hyper-responsiveness in children with allergic rhinitis: relationship with the atopic status
2003
An increased prevalence of bronchial hyper-responsiveness (BHR) has been demonstrated in children from a general population, and in non-asthmatic adults with allergic rhinitis. Thus, also children with allergic rhinitis are expected to be at higher risk of BHR. We evaluated the prevalence of BHR in a sample of non-asthmatic children with allergic rhinitis by means of the methacholine (Mch) bronchial challenge, and by monitorizing the airway patency using the daily peak expiratory flow variability (PEFv). Fifty-one children (ranged 6-15 years of age) with allergic rhinitis, ascertained by skin prick test to inhalant allergens, underwent a 14-day peak expiratory flow monitoring, and a Mch bro…
Mutual intelligibility among the sign languages of Belgium and the Netherlands
2015
AbstractIn an exploratory study of mutual intelligibility between the sign languages of the northern part of Belgium (Flemish Sign Language, VGT), the southern part of Belgium (French Belgian Sign Language, LSFB), and the Netherlands (Sign Language of the Netherlands, NGT), we tested the comprehension of VGT by signers of LSFB and NGT. In order to measure the influence of iconic structures (classifier constructions and constructed action) that linguistic analyses have shown to be similar across different sign languages, two genres were compared: narrative and informative signing. To investigate the effect of the overlap between the spoken languages surrounding the Dutch and Flemish Deaf com…
An exploratory study on the attitudes of elderly Finns towards Russian-speaking minorities
2018
Research has shown Russian speakers in Finland are often victims of prejudice and discrimination. Utilizing integrated threat theory, this study investigated the extent to which threats are signifi...
Pharmacokinetic interaction between efavirenz and ketoconazole in rats
2009
It is well known that efavirenz and ketoconazole act as an inducer and inhibitor of CYP3A4, respectively. As a result of these actions, co-administration of these drugs may result in changes in the pharmacoki- netic parameters of one or both of them. 2. Duodenum-cannulated rats have been used to compare the effect of intraduodenal (KC i.d. ) and intrave- nous administration of ketoconazole (KC i.v. ) on the pharmacokinetics of efavirenz after intraduodenal administration, as well as the potential effect of efavirenz as a CYP450 inducer on ketoconazole phar - macokinetic profile. 3. While KC i.v. did not show any significant effect on efavirenz pharmacokinetic profile, KC i.d. increased sig-…
