Instagram, una herramienta de aprendizaje para el alumnado universitario
No full textTrabajo presentado en: XXIX Jornadas Internacionales Universitarias de Tecnología Educativa (JUTE 2022) "Aprender entre imágenes y pantallas", celebradas los días 15, 16 y 17 de junio de 2022 en la Facultat de Filosofia i Ciències de l’Educació de la Universitat de València.Instagram se ha convertido en una de las redes sociales de mayor uso para la socialización y expresión entre la juventud y es un fenómeno que trasciende al ámbito educativo y laboral. Se describe una experiencia de uso de Instagram en estudiantes del Grado de Maestro de Educación Primaria, Educación Infantil y Educación Social de la Universidad de Burgos, así como su posterior análisis. Se planteó un doble objetivo: comprender cómo se utiliza esta red social como complemento en las clases de tecnología educativa y, por otro lado, analizar las publicaciones de contenido relacionadas con la asignatura por parte del alumnado. Para ello se ha utilizado una metodología que combina el análisis cuantitativo de las publicaciones realizadas por el alumnado en Instagram combinado con el estudio cualitativo de las temáticas abordadas por el estudiantado. Un avance de los primeros hallazgos sobre el potencial formativo de esta plataforma revela ciertas ventajas en el acceso a la información y en la expresión del aprendizaje para el alumnado universitario. Se ha tener en cuenta que para los futuros educadores y educadoras es esencial conocer ejemplos de buen uso de la tecnología a nivel educativo, así como conocer sus limitaciones para que su labor pueda trascender al ámbito profesional
La iniciativa legislativa popular – democracia lift: una aproximación teórica a los derechos brasileño y español con algunas propuestas de reforma para Brasil
No full textEstudiar la iniciativa legislativa popular, a fin de presentar propuestas para el
perfeccionamiento de la legislación brasileña, es la motivación de la presente
tesis. Se investigaron las legislaciones españolas y de la Unión Europea
buscando identificar elementos que podrían contribuir al perfeccionamiento de
la legislación brasileña que trata de esta proyección del ejercicio del derecho
fundamental a la participación popular en el procedimiento legislativo. Se
analizaron los vínculos entre el Estado Constitucional y la democracia, así
como el entrelazamiento entre el macroprincipio de la dignidad de la persona
humana y los derechos políticos, bajo la perspectiva de la existencia de una
crisis de la democracia en el Estado Constitucional. Se trabaja con la hipótesis
de que el perfeccionamiento del sistema normativo brasileño debe tener en
cuenta el modelo habermasiano de democracia deliberativa, basado en la
racionalidad comunicativa fundamentada en la argumentación para alcanzar
un acuerdo intersubjetivo a partir del diálogo.This Doctoral Thesis aims to investigate the constitutional and legal
provisions of the popular legislative initiative in the current Constitutional
States of Brazil and Spain, with the objective of, at the end, presenting
proposals for the improvement of the regulations on the subject in Brazil.
To this end, the starting point will be an analysis of the links between the
Constitutional State and democracy, as well as the intertwining of the
macro-principle of the dignity of the human person and political rights,
from the perspective of the existence of a crisis of democracy in the
Brazilian Constitutional State. The present research aims at the
following: Identify what possible constitutional and/or legal alterations
could be adopted for the improvement of the popular legislative initiative
in Brazil, taking into account its aptitude to contribute, in a
complementary way to representative democracy, to the increase of the
quality of Brazilian democracy, in a constant feedback of the democratic
flow
Dataset of the work “Simultaneous Raman and reflection UV/Vis absorption spectroelectrochemistry”
No full textIn the present work, a new combination of Raman and ultraviolet and visible (UV/Vis) absorption spectroelectrochemistry in reflection mode is proposed. The new experimental setup allows obtaining the two kinds of spectroscopic data without interferences concomitantly with the electrochemical information. To the best of our knowledge, it is the first time to report the simultaneous obtention of electrochemical, electronic, and vibrational information in the same experiment. This new combination provides time-resolved information about the processes that are taking place on the electrode/solution interface which has significant implications in different fields of chemistry, such as modification of electrodes, studies of electrocatalytic reaction mechanisms, development of sensors, among others. Two different systems were used to demonstrate the advantages and capabilities of the brand-new technique, namely, the oxidation of potassium ferrocyanide, an out-sphere system that is usually employed in the validation of SEC techniques, and the electrochemical-surface enhanced Raman spectroscopy (EC-SERS) detection of crystal violet by in-situ formation of the silver SERS substrate, where the UV/Vis spectra were used to follow the formation of the SERS substrate, whereas the Raman response of a probe molecule was used to confirm either the formation of a nanostructured surface and to obtain the fingerprint of the molecule with a high time resolution. The brand-new experimental setup has shown to be useful, versatile, robust, compact, and easy to use for future applications.Authors acknowledge the financial support from Ministerio de Ciencia e Innovacion (No. PID2020-113154RB-C21), Ministerio de Economía, Industria y Competitividad (No. CTQ2017-83935-RAEI/FEDERUE), Junta de Castilla y Leon (No. BU297P18), and Ministerio de Ciencia, Innovacion y Universidades (No. RED2018-102412-T).

Métodos e instrumentos de avaliação em programas de formação por pares para pessoas com problemas de saúde mental: revisão documental
No full textLa formación de las personas con enfermedad mental favorece la inclusión social y laboral. La evaluación de estos programas es fundamental para determinar su alcance. El objetivo es identificar los métodos e instrumentos de evaluación empleados en los programas de formación de pares para personas con enfermedad mental. Se realiza una revisión documental. Según los criterios de inclusión y elegibilidad, se seleccionaron 56 programas para su análisis. Los métodos de evaluación utilizados son muy heterogéneos y la información proporcionada es limitada. Encontramos que la mayoría de los programas evalúa conocimientos, pero no las competencias adquiridas con la formación. Para una adecuada evaluación de competencias, es necesario que se recoja información en diferentes momentos y con estrategias que se complementen; de no actuar de esta forma sería complicado afirmar que la persona cuenta con las competencias necesarias para su desempeño.Training people with mental illnesses promotes social and labour market inclusion. The evaluation of these programs is essential to determine their scope. The aim is to identify the methods and instruments used in the evaluation of peer education programs for people with mental illness. A documentary review has been carried out. According to the inclusion and eligibility criteria, 56 programs were selected for the analysis. We found that the evaluation methods used are very heterogeneous and the provided information is limited; most of the programs evaluate knowledge, but not the acquired competences through training. It is necessary to collect information at different times and with complementary strategies for an adequate evaluation of the competences. If this is not done, it would be difficult to affirm that the person has developed the necessary competences for their tasks.A formação de pessoas com doenças mentais favorece a inclusão social e laboral.

Design and development of a gamified tutorial for iVR serious games
No full textSerious games, including immersive Virtual Reality (iVR) experiences, can be challenging for players due to their unfamiliar control systems and mechanics. This study focuses on designing a gamified tutorial for iVR serious games that not only teaches iVR interactions but also enhances user enjoyment and engagement. The tutorial consists of progressively challenging mini-games that adapt to the user's performance. Tips and recommendations are provided through a robot avatar if users struggle or make mistakes. An optional narrative is included to enhance user engagement, but it is not mandatory for the iVR experience. Gamification elements, such as point collection and progress updates, are incorporated into the tutorial. It can be played independently or as an introduction to iVR serious games. The goal is to use gamificationprinciples to maintain user engagement and flow while enhancing the learning experience in the virtual world.This work was partially supported by the ACIS project (Reference Number INVESTUN/21/BU/0002) of the Consejeria de Empleo e Industria of the Junta de Castilla y León (Spain), the Erasmus+ RISKREAL Project (2020-1- ES01-KA204-081847) of the European Commission and the HumanAid Project (TED2021-129485B-C43) of the Proyectos Estraté-gicos Orientados a la Transición Ecológica y Digital of the Spanish Ministry of Science and Innovation

Data Augmentation Effects on Highly Imbalanced EEG Datasets for Automatic Detection of Photoparoxysmal Responses
No full textPhotosensitivity is a neurological disorder in which a person’s brain produces epileptic discharges, known as Photoparoxysmal Responses (PPRs), when it receives certain visual stimuli. The current standardized diagnosis process used in hospitals consists of submitting the subject to the Intermittent Photic Stimulation process and attempting to trigger these phenomena. The brain activity is measured by an Electroencephalogram (EEG), and the clinical specialists manually look for the PPRs that were provoked during the session. Due to the nature of this disorder, long EEG recordings may contain very few PPR segments, meaning that a highly imbalanced dataset is available. To tackle this problem, this research focused on applying Data Augmentation (DA) to create synthetic PPR segments from the real ones, improving the balance of the dataset and, thus, the global performance of the Machine Learning techniques applied for automatic PPR detection. K-Nearest Neighbors and a One-Hidden-Dense-Layer Neural Network were employed to evaluate the performance of this DA stage. The results showed that DA is able to improve the models, making them more robust and more able to generalize. A comparison with the results obtained from a previous experiment also showed a performance improvement of around 20% for the Accuracy and Specificity measurements without Sensitivity suffering any losses. This project is currently being carried out with subjects at Burgos University Hospital, Spain.This research was funded by the Spanish Ministry of Economics and Industry, Grant PID2020-112726RB-I00, by the Spanish Research Agency (AEI, Spain) under Grant agreement RED2018-102312-T (IA-Biomed), and by the Ministry of Science and Innovation under CERVERA Excellence Network project CER-20211003 (IBERUS) and Missions Science and Innovation project MIG-20211008 (INMERBOT), as well as by Principado de Asturias, Grant SV-PA-21-AYUD/2021/50994
