Validation in Spanish of a Global Competence Scale in Pre-service and In-service Teachers
No full textLa competencia global como objetivo de aprendizaje es cada vez más requerida por distintas instituciones educativas. Evaluar esta competencia supone un reto por su complejidad y para ello se necesitan instrumentos válidos. Al no encontrar instrumentos en castellano que permitan evaluar esta competencia en educación superior se diseña este estudio que se centra en adaptar y validar una escala sobre Competencia Global al contexto español. La muestra incluyó 736 participantes, 358 docentes en servicio y 378 docentes en formación. Los resultados del análisis factorial exploratorio (AFE) y confirmatorio (AFC) apoyaron la estructura de un factor que difiere del modelo original. El modelo de un factor alcanza un buen ajuste una vez eliminado un ítem relacionado con la comunicación intercultural. El AFC muestra que la escala de 8 ítems alcanza una bondad de ajuste suficiente y una fiabilidad correcta, aunque el modelo con 7 ítems alcanza mejor bondad de ajuste manteniendo una buena fiabilidad. Finalmente, los resultados del análisis factorial confirmatorio multigrupo (AFCM) apoyaron la invarianza configuracional y métrica del modelo de medida según sexo. La validez externa confirma la correlación entre la competencia global y los valores de universalismo y benevolencia (Transcendencia). Se concluye que la escala de 7 ítems de Competencia Global presenta adecuadas propiedades psicométricas y buena fiabilidad para medir la Competencia Global en educación superior. Futuros estudios podrían explorar la mejora de la dimensión de comunicación intercultural de esta escala en la versión en castellano.Global competence as a learning objective is increasingly required by different educational institutions. Assessing this competence is a challenge due to its complexity and valid instru-ments are needed. As there are no instruments in Spanish to assess this competence in higher education, this study was designed to adapt and validate a scale on global competence within the Spanish context. The sample included 736 participants, 358 in-service teachers and 378 trainee teachers. The results of the exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) supported a one-factor structure that differs from the original model. The one-factor model achieves a good fit once one item related to intercultural communication is removed. The CFA shows that the 8-item scale attains sufficient goodness-of-fit and good reliability, although the 7-item model achieves better goodness-of-fit while maintaining good reliability. Finally, the results of the Multigroup Confirmatory Factor Analysis (MCFA) supported the configurational and metric invariance of the measurement model according to gender. External validity confirms the correlation between global competence and the values of universalism and benevolence (Transcendence). It is concluded that the 7-item global competence scale presents adequate psychometric properties and good reliability for measuring global competence in higher education. Future studies could explore the improvement of the intercultural communication dimension of this scale in the Spanish version
Development of Executive Functions and Creativity in Early Childhood Education
No full textIntroducción: el desarrollo de las funciones ejecutivas en la autorregulación de la conducta y desarrollo de procesos cognitivos de orden superior pone en evidencia su importancia en el éxito escolar y social. Algunos estudios sugieren que puede existir relación con la creatividad, siendo de gran relevancia determinar los procesos de desarrollo de ambos conceptos y ver su relación. Objetivo: estudiar la relación entre funciones ejecutivas y creatividad en una muestra de alumnos de edades comprendidas entre los 3 y los 5 años y 11 meses. Materiales y método: para medir la función ejecutiva se utilizó el BRIEF-P (Gioia et al., 2016) y para la medir la creatividad el cuestionario de creatividad de Tuttle (1980). La correlación se midió mediante estadística paramétrica. Resultados: los resultados mostraron que existe relación estadísticamente significativa entre la creatividad y el Índice General de Función Ejecutiva (IGE), existe correlación significativa con el Índice de Metacognición Emergente (IME) sin embargo, no se encontró relación entre los índices de Autocontrol Inhibitorio (IAI) y de Flexibilidad (IFL). Los alumnos de menor edad presentan mayores dificultades en las escalas de inhibición, flexibilidad y control emocional. Conclusiones: la existencia de relación entre la función ejecutiva y la creatividad abre la puerta a más investigaciones en este campo, siendo necesario ampliar la muestra. Se señala la importancia de diseñar e implementar programas educativos en la etapa de Educación Infantil para potenciarlas.Introduction: The development of executive functions in the self-regulation of behavior and the development of higher-order cognitive processes highlight their importance in academic success. Some studies suggest that there may be a relationship with creativity, making it highly relevant to determine the developmental processes of both concepts and to explore their relationship. Objective: To study the relationship between executive functions and creativity in a sample of students aged between 3 years and 5 years and 11 months. Materials and Method: The BRIEF-P (Gioia et al., 2016) was used to measure executive function, and Tuttle’s creativity questionnaire (1980) was used to measure creativity. The correlation was measured using parametric statistics. Results: The results showed a statistically significant relationship between creativity and the Global Executive Function Index (GEFI), with a significant correlation with the Emerging Metacognition Index (EMI). However, no relationship was found between the Inhibitory Self-Control Index (ISCI) and the Flexibility Index (FI). Younger students showed more difficulties in the scales of inhibition, flexibility, and emotional control. Conclusions: The existence of a relationship between executive function and creativity opens the door to further research in this field, with an expansion of the sample size being necessary. It highlights the importance of designing and implementing educational programs in Early Childhood Education to enhance these skills
Spectroelectrochemical studies of TDMQ20: A potential drug against Alzheimer’s disease
No full textAlzheimer’s Disease (AD), reported for the first time in 1906, is a common disease that remains incurable to this day. In the past, a family of treatments using Cu(II) chelators failed during clinical trials, evidencing the importance of pre-clinical studies. In this work, we performed electrochemical characterisation of TDMQ20, a new potential drug against AD, using electrochemistry and spectroelectrochemistry. On the basis of voltammetry, we determined that TDMQ20 undergoes a two-step irreversible oxidation process and a one-step irreversible reduction process. Both oxidation and reduction reactions are pH-sensitive. Bidimensional UV–Vis spectroelectrochemistry (UV–Vis-SEC) allowed us to confirm that oxidation of TDMQ20 can occur both on the aliphatic chain and on the aromatic ring. The results expand the knowledge of the TDMQ20 redox activity in the human body which is important from the point of view of the toxicity of the proposed therapy.This work has been financially supported by the National Science Centre Poland within the Sonatina project 2021/40/C/ST4/00090
Initial Approach to a Self-Compacting Concrete with Waste from Crushed Wind Turbine Blade
No full textComunicación presentada en: International Conference on Technology Enabled Civil Infrastructure Engineering and Management (TECH-IEM) 2023, durante los días 15-16 de diciembre en Karachi (Pakistán)Wind energy has been making its way into renewable energies until today, experiencing a continuous growth worlwide that leads to the urgent task of reflecting on and solving the issue of the recycling of the wind turbine blades. Their complex composition causes that currently there is no a widely acepted solution for it. This study evaluates the incorporation of waste from the crushing of wind turbine blades, which contains fibers, into self-compacting concrete, which can be used for producing any construction element. Therefore, five concrete mixes were made with different percentages of this waste, including a reference mix without this waste. The addition of waste increased the content of fibers in the concrete, which in turn implied an increase in the water/cement ratio. This situation led to a worsening of the mechanical performance of concrete as the waste amount increased, although it was partially compensated by the stitching effect of the fibers. The concrete mix with 1.5% in volume of this waste exhibited flexural and compressive strengths very similar to those of the reference concrete. This shows that incorporating the waste from the crushing of wind turbine blades can allow to produce structural self-compacting concrete.This research work was supported by the Spanish Ministry of Universities, MICINN, AEI, EU, ERDF and NextGenerationEU/PRTR [grant numbers PID2020-113837RB-I00; 10.13039/501100011033; TED2021-129715B-I00; FPU21/04364]; the Junta de Castilla y León (Regional Government) and ERDF [grant number UIC-231; BU066-22]; and, finally, the University of Burgos [grant number SUCONS, Y135.GI]
LoDCalculator: A level of detail classification software for 3D models in the Blender environment
No full textThe use of Level of Detail (LoD), a crucial technique in the development of 3D models, implies lower cost graphics and resource economies. These savings are evident in contexts where technical resources are limited, such as immersive Virtual Reality and whenever LoD is critical for accurate representation, such as Cultural Heritage dissemination. Consequently, various systems are used to classify 3D models based on their LoD. However, those systems have several shortcomings that hinder their widespread use. In this research, LoDCalculator, an add-on for Blender open-source modelling software, is presented to address such shortcomings. LoDCalculator ensures unambiguous, universal, and accessible classification of 3D models. It was tested by classifying 12 3D models. The scores were then compared with the evaluations of a group of students and professional 3D modelers in a subjective evaluation. The results of the comparison were satisfactory, showing minimal significant differences between the software and the evaluation group classifications.This work was supported by the Ministry of Science and Innovation of Spain (MCIN/AEI/10.13039/501100011033) and by the European Union NextGenerationEU/PRTR through REMAR Project (CPP2022-009724)
Field study evolution on a porous asphalt mixture pavement containing ladle furnace slag
No full textA three-year study tracking the performance of a novel, environmentally sustainable pavement, a Porous Asphalt (PA) mix incorporating Ladle Furnace (LF) slag, is presented in this paper. A thin layer of this material was applied over an existing pavement, in a pilot project of approximately 300 m2. The main results of the research refer to the successful scaling up from laboratory design to full-scale manufacturing, laying, and compaction, validating the use of up to 10 % LF slag in the mixture. The pavement demonstrated satisfactory durability in terms of resistance to abrasion, accelerated aging, frost, and humidity. The leaching behavior of the mixture remained well below regulatory limits. Over the three-year monitoring period, skid resistance remained stable, consistently exceeding 70 BPN (British Pendulum Number), while the permeability coefficient in dust-protected areas was maintained at 10⁻¹ cm/s. Moreover, visual inspections revealed no surface deficiencies throughout the study.This work was supported by [MICINN, AEI and ERDF] under grant [PID2020–113837RB-I00; 10.13039/501100011033]; and [Junta de Castilla y León and ERDF] under grant [Plan TCUE, VIIIPC_05]
