Potencialidades de Google Maps en la investigación social aplicada
2019
In recent years, Google has devoted resources to build a complete map of the world. They constantly scan the territory, collecting a large amount of data that provides updated and complete geographic information. This allows us to have an interoperable map that provides the end user with a search tool, not only of routes but also of shops, equipment and any type of geo-referenced information. In addition, Google Maps provides a series of Application Programming Interface (API), which provides a library of set of subroutines, functions and procedures (in object-oriented programming) that can be used by other software to automate the extraction of information of the Google platform. These fre…
Design, validation, and testing of an observational tool for technical and tactical analysis in the taekwondo competition at the 2016 Olympic games.
2020
Abstract Observational methodology uses validated observational tools to collect information in sports with multiple variables that interact in the sporting context. Given the importance of data quality for observational tools, the purpose of this study was to design, validate, and test the reliability of a mixed observational instrument combining field formats and category systems for analyzing technical and tactical actions in an Olympic taekwondo (TKD) tournament. The instrument collects information of six criteria and 25 categories of the tactical and technical actions, kicking zone, laterality, kicking leg, guard, and score. A total of 2 374 actions were analyzed from 10 bouts involvin…
Fast simultaneous determination of prominent polyphenols in vegetables and fruits by reversed phase liquid chromatography using a fused-core column
2015
A reversed-phase high-performance liquid chromatography method with photodiode array detection has been developed enabling the joint determination of 17 prominent flavonoids and phenolic acids in vegetables and fruits. A multi-segmented gradient program using a fused-core column for the separation of several phenolic classes (phenolic acids and flavonoids) has been optimised. The influence of extraction conditions (sample freeze-drying, ultrasound extraction, solvent composition and extraction time) has been also optimised using response surface methodology with tomato samples as a model. Complete recoveries (76-108%) were obtained for the phenolic compounds present in tomato. The developed…
Aportaciones de la herpetofauna al conocimiento de la paleobiología y paleoclimatología del tramo temporal Pleistoceno Superior y Holoceno de la Comu…
2022
El periodo Cuaternario se caracteriza climáticamente por la alternancia de fases glaciales e interglaciales, y, asociadas a ellas, importantes fluctuaciones de la línea de costa. Dado que este marco temporal es altamente relevante en el campo de la evolución humana y, por ello, gran parte de su estudio se ha centrado en esta temática; también lo es para entender diversos aspectos de la historia natural de otros grupos de vertebrados, como es el caso de los reptiles y anfibios. Hasta ahora son escasos los estudios del componente herpetológico de las faunas de vertebrados en el este de la península ibérica durante el Pleistoceno Superior y Holoceno, habiéndose centrado fundamentalmente este e…
Liderazgo femenino y felicidad en el trabajo: el papel mediador del intercambio líder-colaborador
2018
Objetivo: el objetivo de este artículo es examinar el papel del liderazgo femenino en la felicidad en el trabajo de sus colaboradores. Además, se analiza el papel mediador de la relación entre el líder y el colaborador, entendida como el intercambio líder-colaborador (LMX). Método: se ha utilizado la encuesta como método de investigación; se analizaron datos cuantitativos a nivel individual a través de modelos de ecuaciones estructurales. La muestra está compuesta por 292 empleados no directivos del sector hotelero español, para los que se analiza su percepción individual acerca de las variables objeto de estudio. Resultados: los resultados revelan que el liderazgo femenino ejerce un papel …
Individual and culture-level components of survey response styles: A multi-level analysis using cultural models of selfhood
2016
Variations in acquiescence and extremity pose substantial threats to the validity of cross-cultural research that relies on survey methods. Individual and cultural correlates of response styles when using 2 contrasting types of response mode were investigated, drawing on data from 55 cultural groups across 33 nations. Using 7 dimensions of self-other relatedness that have often been confounded within the broader distinction between independence and interdependence, our analysis yields more specific understandings of both individual- and culture-level variations in response style. When using a Likert-scale response format, acquiescence is strongest among individuals seeing themselves as simi…
High Pressure Processing Impact on Emerging Mycotoxins (ENNA, ENNA1, ENNB, ENNB1) Mitigation in Different Juice and Juice-Milk Matrices
2022
The aim of the present study was to investigate the potential of high-pressure processing (HPP) (600 MPa during 5 min) on emerging mycotoxins, enniatin A (ENNA), enniatin A1 (ENNA1), enniatin B (ENNB), enniatin B1 (ENNB1) reduction in different juice/milk models, and to compare it with the effect of a traditional thermal treatment (HT) (90 °C during 21 s). For this purpose, different juice models (orange juice, orange juice/milk beverage, strawberry juice, strawberry juice/milk beverage, grape juice and grape juice/milk beverage) were prepared and spiked individually with ENNA, ENNA1, ENNB and ENNB1 at a concentration of 100 µg/L. After HPP and HT treatments, ENNs were extracted from treate…
Spanish Nurses’ Knowledge about Palliative Care. A National Online Survey
2021
(1) Background: Nurses can find people with advanced diseases or in their last days of life during their professional careers and in many different care settings. For this reason, they need to have at least a basic level of palliative care education since they are the professional cohort treating these patients in a very close way. This research aims to determine the level of knowledge in palliative care of Spanish nurses and establish any possible difference based on their experience and training in palliative care. (2) Methods: A cross-sectional design using survey methods (distributed an online questionnaire) aimed at Spanish registered nurses. A validated questionnaire (PCQN-SV) was use…
Can Emotional Competence Be Taught in Higher Education? A Randomized Experimental Study of an Emotional Intelligence Training Program Using a Multime…
2018
Since the introduction of the Bologna Process, the goal of education has been not only to acquire technical skills but also to master other skills, such as teamwork, effective communication skills, time optimization, and the ability to manage one's emotions. The present work describes a program to develop emotional intelligence in higher education, the “Emotional Intelligence Training Program,” with a multimethodological approach that offers the opportunity for university students to develop their emotional intelligence. A total of 192 higher education students participated in this educational experience. Of the participants, 66% were women, and 34% were men; the average age of the sample w…
Fostering general and specific competences through online language learning materials
2011
This paper addresses how general and specific competences are dealt with and fostered through the Online First Certificate Course and Tester, designed by the CAMILLE Research Group in Spain. The debate and research on the role of competences is an ongoing issue within the field of higher education. Moreover, the new framework of the European Higher Education Area (EHEA) has made it more visible and has contributed towards designing and implementing new educational curricula based on a competence-based approach.
