A local complexity based combination method for decision forests trained with high-dimensional data
2012
Accurate machine learning with high-dimensional data is affected by phenomena known as the “curse” of dimensionality. One of the main strategies explored in the last decade to deal with this problem is the use of multi-classifier systems. Several of such approaches are inspired by the Random Subspace Method for the construction of decision forests. Furthermore, other studies rely on estimations of the individual classifiers' competence, to enhance the combination in the multi-classifier and improve the accuracy. We propose a competence estimate which is based on local complexity measurements, to perform a weighted average combination of the decision forest. Experimental results show how thi…
La representación de la protesta contra Educación para la Ciudadanía en ABC y La Razón
2013
El objetivo de este trabajo es indagar en el tratamiento periodístico que recibió la protesta en contra de la asignatura Educación para la Ciudadanía por parte de los dos diarios ideológicamente más próximos a los impulsores de la controversia. El análisis se centra entre los años 2004 y 2008, periodo durante el que el conflicto en torno a esta materia fue más intenso. Para ello, realizamos un exhaustivo análisis de contenido de 650 piezas informativo-interpretativas. Los resultados señalan que la presentación negativa de la materia dominó en una cobertura cómplice con los críticos y escasamente explicativa. The aim of this work is to study the journalistic treatment that the protest agains…
Noticing-prefaced recoveries of the interactional space in a video-mediated business meeting
2020
Drawing on conversation analysis and authentic data from a video-mediated multiparty meeting, this study investigates the sequential and temporal organisation of recoveries of the interactional space. It focuses on moments in which either an auditory or a visual barrier emerges, and the participants orient to these troubles through intensified bodily-visual displays: embodied noticings. The analysis illustrates noticing-prefaced recoveries of the interactional space as procedural and multimodal accomplishments that require close attentiveness to the co-participants’ verbal and visual conduct and to the contingencies of the meeting. The study highlights not only the affordances of video-medi…
A commentary on the Special Issue “Innovations in measuring and fostering mathematical modelling competencies”
2021
This is a commentary on the ESM 2021 Special Issue on Innovations in Measuring and Fostering Mathematical Modelling Competencies. We have grouped the ten studies into three themes: competencies, fostering, and measuring. The first theme and the papers therein provide a platform to discuss the cognitivist backgrounds to the different conceptualizations of mathematical modelling competencies, based on the modelling cycle. We suggest theoretical widening through a competence continuum and enriching of the modelling cycle with overarching, analytic dimensions for creativity, tool use, metacognition, and so forth. The second theme and the papers therein showcase innovative ideas on fostering an…
AX-PET: Concept, proof of principle and first results with phantoms
2010
AX-PET is a novel PET concept based on long crystals axially arranged and orthogonal Wavelength shifter (WLS) strips, both individually readout by Geiger-mode Avalanche Photo Diodes (G-APD). Its design was conceived in order to reduce the parallax error and simultaneously improve spatial resolution and sensitivity. The assessment of the AX-PET concept and potential was carried out through a set of measurements comprising individual module characterizations and scans in coincidence mode of point-like and extended sources. The estimated energy and spatial resolutions from point-like measurements are R FWHM =11.6% (at 511 keV) and 1.7–1.9 mm (FWHM) respectively as measured with point-like sour…
New media and perennial problems in foreign language learning and teaching
2015
The book concerns the ways in which the new media shape communication along with educational expectations and practices in foreign language classrooms. Although foreign language learners have cheap and easy access to information and ways of communication, they also wrestle with problems that have always accompanied language learning. The focus of the book is two-fold. On the one hand, the authors demonstrate how using social networks, videoconferencing, mobile phones, wikis, and computer-mediated interaction contributes to the development of language skills, negotiated interaction, autonomy, and intercultural competence. On the other, they discuss “old” issues pertaining to the role of voca…
Estudio de la relación entre miembros del comité editorial de las revistas científicas de Psicología y su producción según diferentes indicadores bib…
2017
[ES]: El objetivo del presente trabajo es estudiar la relación entre los miembros del comité editorial que publican artículos en revistas de las que forman parte y la propia revista. Los resultados apuntan que los miembros del comité editorial publican sus artículos de forma más rápida frente a los autores que no forman parte del comité, y que no existe colaboración entre los miembros con mayor presencia en diferentes comités, sí habiéndola entre miembros de una misma revista. En 6 de las 10 revistas estudiadas el porcentaje de artículos firmados por algún miembro del comité supera el 25%, y en tres de estas revistas el tiempo de publicación de estos artículos es significativamente inferior…
BUSINESS CAPABILITIES AND HR KNOWLEDGE’ AS THE CRITICAL FACTOR OF DUE DILIGENCE IN PRE-ACQUISITION PHASE
2016
Previous theoretical research has argued that due diligence in the pre-acquisition phase is traditionally oriented towards legal and financial matters. However, in the innovation-driven market environment, where firms need to maintain competitive strength, business skills and knowledge play important roles. Despite this difference, the due diligence research continues in traditional areas, e.g., financial history, legal and commercial liabilities, and tax issues. Hence, the problem may arise in acquirers overpaying or mistakenly rejecting a target firm. There is a need for assessing ‘Business Capabilities and Human Resources Knowledge’ for due diligence in the pre-acquisition phase. Based o…
Blending Literature and Foreign Language Learning: Current Approaches
2013
The aim of this chapter is to discuss the place of literature in foreign language learning and teaching contexts, and to show reasons of using literary texts for the development of communicative competence, intercultural communicative competence, and for individual as well as social human growth. Although literature and language teaching had been following separate paths, currently a strong tendency emerges of integrating language and literature teaching across proficiency levels. This tendency results from the recognition of the roles that literacy, multiliteracies and multimodality play in the life of humans in the 21st century. Respected bodies such as the Council of Europe or Modern Lan…
Znawca języka czy człowiek komunikujący się? O strukturze kompetencji językowo-komunikacyjnej ucznia klas IV–VI szkoły podstawowej wpisanej w podstaw…
2019
The article aims to answer two questions: how the language instruction framework was inscribed into the 2017/2018 Polish language curriculum and what image of the linguistic and communicative competence results from this document. The research method is based on the assumption that these two questions can be answered by analysing the cognitive operators used in the description of specific requirements. The article analyses the operators found in the ‘language instruction’ section of the curriculum. Within the linguistic and communicative competence, the document distinguishes among metalinguistic, analytical, linguistic (including normative and grammar-lexical competences) and communicative…
