3D visualization through the hologram for the learning of area and volume concepts
(Mathematics, 26/02/2019)This study aims to implement and evaluate a methodological proposal using the hologram as a teaching medium for the learning of concepts related to areas and volumes of geometrical bodies. The study has been carried out ... -
A 14-year dataset of in situ glacier surface velocities for a tidewater and a land-terminating glacier in Livingston Island, Antarctica
(Earth System Science Data, 10/2017)We present a 14-year record of in situ glacier surface velocities determined by repeated global navigation satellite system (GNSS) measurements in a dense network of 52 stakes distributed across two glaciers, Johnsons ... -
A biparametric extension of King’s fourth-order methods and their dynamics
(Applied Mathematics and Computation, 05/2016)A class of two-point quartic-order simple-zero finders and their dynamics are investigated in this paper by extending King’s fourth-order family of methods. With the introduction of an error corrector having a weight ... -
A cluster-analytic profiling of heroin-dependent patients based on level, clinical adequacy, and patient-desired adjustment of buprenorphine dosage during buprenorphine-naloxone maintenance treatment in sixteen Spanish centers
(Drug and Alcohol Dependence, 2018)Background: Buprenorphine dosage is a crucial factor influencing outcomes of buprenorphine treatment for heroin use disorders. Therefore, the aim of the present study is to identify naturally occurring profiles of ... -
A clustering WSN routing protocol based on k-d tree algorithm
(Sensors, 09/2018)Clustering in wireless sensor networks has been widely discussed in the literature as a strategy to reduce power consumption. However, aspects such as cluster formation and cluster head (CH) node assignment strategies have ... -
A consensus support model based on linguistic information for the initial-self assessment of the EFQM in health care organizations
(Expert Systems with Applications, 06/2013)The improvement of the quality of the services is one of the primary sources of competitive advantage in health care organizations. As customers typically search for higher quality of care when choosing treatments, health ... -
A corpus-based study of adverbs of frequency in a goal-oriented distance learning forum
(ELIA. Estudios de Lingüística Inglesa Aplicada, 2018)This paper reports on a corpus-based study that investigated the use of frequency adverbs in students' posts in a goal-oriented virtual forum. The participants in the study were undergraduate students enrolled in two ... -
A crusade over the airwaves: the Blue Division on Radio Nacional de España (1941–1954)
(Historical Journal of Film, Radio and Television, 2017)The Blue Division, Spain’s most notable military contribution to the Second World War, has been examined from many different perspectives, though the role of communication has not featured among them. This study aims to ... -
A design process for balanced educational video games with collaborative activities
(Dyna, 2015)The efficiency of educational video games could be improved through the use of a specific development method that allows them to keep both their educational and recreational goals and maintains their playability. Accordingly, ... -
A first overview on the real dynamics of Chebyshev's method
(Journal of Computational and Applied Mathematics, 07/2017)In this paper we explore some properties of the well known root-finding Chebyshev’s method applied to polynomials defined on the real field. In particular we are interested in showing the existence of extraneous fixed ... -
A Gap in Networked Publics? A Comparison of Younger and Older Journalists' Newsgathering Practices on Social Media
