Narrative writing in initial teacher training as an experiential epistemological turn
No full textLa investigación cuenta con el apoyo financiero de la Agencia Nacional de Investigación (ANID-Chile) al proyecto de investigación Fondecyt de Iniciación 11231121 ―Pedagogías narrativas en la formación inicial docente‖.Este estudio explora cómo la formación docente puede transitar hacia un enfoque epistemológico más centrado en la experiencia, buscando superar la desconexión entre la teoría y la práctica. Desde una perspectiva descriptiva e interpretativa, esta investigación fenomenológica y hermenéutica examina el empleo de la escritura narrativa como herramienta formativa en la educación inicial de futuros profesores; concretamente, en el contexto del practicum (práctica progresiva inicial) en Chile. El análisis temático de las experiencias reflexivas de 45 estudiantes da cuenta de tres dimensiones significativas: a) la importancia de la mirada subjetiva al momento de recobrar y profundizar en las experiencias, b) la centralidad que adquiere la presencia de los estudiantes en el relato y c) la afirmación de una vocación pedagógica con la educación de las otras y otros. Finalmente, estos hallazgos subrayan la potencialidad formativa de la narración de experiencias para la formación inicial, donde la escritura reflexiva no solo facilita la formación de saberes prácticos, sino que también contribuye al desarrollo de una identidad docente más consciente y comprometida.This study explores how teacher training can transition towards a more experience-centered epistemological approach, seeking to overcome the disconnection between academic theory and real educational practices. From a descriptive and interpretative perspective, this phenomenological and hermeneutic research examines the use of narrative writing as a formative tool in the initial education of future teachers, especially in the context of the practicum in Chile. Through a thematic analysis of reflective experiences by 45 students, three key dimensions are identified: the importance of the subjective perspective when recalling and deepening experiences, the centrality of the students' presence in the narrative, and the affirmation of a pedagogical vocation in the education of others. Finally, these findings underscore the need to integrate narrative methodologies in teacher training, where reflective writing not only facilitates the formation of practical knowledge but also contributes to the development of a conscious and committed teacher identity.Agencia Nacional de Investigación (Chile) 1123112
Empirical Evaluation of a 5G Transparent Clock for Time Synchronization in a TSN-5G Network
No full textThis work has been financially supported in part by the Ministry for Digital Transformation and of Civil Service of the Spanish Government through the TSI-063000-2021-28 project, and by the European Union through the Recovery, Transformation and Resilience Plan- NextGenerationEU, and by grant PID2022-137329OB-C43 funded by MICIU/AEI/ 10.13039/501100011033 and by ERDF/EU, by the Spanish Ministry of Universities (FPU Grant 21/04225) and by the Spanish Ministry of Universities (FPU Grant 20/02621).Time synchronization is essential for industrial IoT and Industry 4.0/5.0 applications, but achieving high synchronization accuracy in Time-Sensitive Networking (TSN)-5G networks is challenging due to jitter and asymmetric delays. 3GPP TS 23.501 defines three 5G synchronization modes: time-aware system, boundary clock (BC), and transparent clock (TC), where TC offers a promising solution. However, to the best of our knowledge, there is no empirical evaluation of TC in a TSN5G network. This paper empirically evaluates an 5G end-to-end TC in a TSN-5G network, implemented on commercial TSN switches with a single clock. For TC development, we compute the residence time in 5G and recover the clock domain at the slave node. We deploy a TSN-5G testbed with commercial equipment for synchronization evaluation by modifying the Precision Timing Protocol (PTP) message transmission rates. Experimental results show a peak-to-peak synchronization of 500 ns, meeting the industrial requirement of ≤ 1 µs, with minimal synchronization offsets for specific PTP message transmission rates.Spanish Government TSI-063000-2021-28NextGenerationEUMICIU/AEI/ 10.13039/501100011033 PID2022-137329OB-C43ERDF/EUSpanish Ministry of Universities (FPU Grant 21/04225), (FPU Grant 20/02621
Music Education in Spain: comparative study on LOMCE and LOMLOE in primary education stage
No full textLa educación musical es un componente clave en la educación del alumnado, siendo objeto de regulación por parte de las instituciones educativas con competencias en este ámbito. A través de la legislación, cada sistema educativo nacional estructura el aprendizaje de sus ciudadanos, dando lugar a los currículos que guiarán la práctica educativa docente. En este artículo abordaremos el concepto de currículo para atender posteriormente a través del método comparado al estudio de las enseñanzas mínimas de Educación Musical en la LOMCE y en la LOMLOE en la etapa de educación primaria, analizando sus semejanzas y diferencias en cuanto a la presencia de los elementos curriculares de introducción al área, competencias, contenidos, evaluación y metodología por un lado y de los componentes musicales de la escucha, la expresión, el lenguaje de la música, la producción musical, el uso de TIC/TAC y el fomento de la cultura musical por otro. Los resultados ponen de manifiesto una mejora en la presencia de los elementos curriculares y en los componentes musicales establecidos en la actual legislación educativa, especialmente en lo referente al ámbito de la escucha, del lenguaje de la música y de la producción musical, destacando como aspectos muy positivos la incorporación de competencias específicas para la Educación Artística y el establecimiento de esta disciplina como obligatoria en la etapa de educación primaria.Music education is a key component of pupils' education and is regulated by the educational
institutions with competences in this field. Through legislation, each national education system
structures the learning of its citizens, giving rise to the curricula that guide educational practice. In
this article, we will address the concept of curriculum in order to then use the comparative method
to study the minimum teaching requirements for Music Education in LOMCE and LOMLOE in primary
education, analysing their similarities and differences in terms of the presence of the curricular
elements of introduction to the area, competences, content, assessment and methodology on the
one hand, and the musical components of listening, expression, the language of music, music
production, the use of ICT and the promotion of musical culture on the other. The results show an
improvement in the presence of the curricular elements and musical components established in the
current educational legislation, especially with regard to the field of listening, the language of
music and musical production, highlighting as very positive aspects the incorporation of specific
competences for Art Education and the establishment of this discipline as compulsory at the
primary education stage
Be Warned of the Contracted Relationship: the Choice of Baptismal Godparents in the City of Ávila in the 18th Century

investigación “Familia, dependencia y conflicto en España, 1700-1860”, PID2024-159231NB-I00.Al ablucionar el cuerpo del recién nacido en el sacro fonte, se limpiaba la mácula del pecado de su alma mientras se le daba la bienvenida a la comunidad. Un rito de iniciación cristiana que, más allá de las implicaciones religiosas que conllevaba, marcaba el devenir social de la parentela del neófito como consecuencia de los lazos de parentesco espiritual que se creaban. En este artículo nos proponemos estudiar la aplicación del rito y la elección de padrinos en la ciudad de Ávila a lo largo del siglo XVIII. Prestando atención a la antroponimia y homonimia, a los modelos de padrinazgo documentados, a las relaciones consanguíneas existentes entre padres espirituales y ahijados y a los motivos que dieron lugar a su elección.By ablucing the body of the newborn in the sacro fonte, the stain of sin was cleansed from his soul while he was welcomed into the community. A rite of Christian initiation that, beyond the religious implications it entailed, marked the social future of the neophyte’s relatives as a consequence of the ties of spiritual kinship that were created. In this article we propose to study the application of the rite and the election of godparents in the city of Ávila throughout the 18th century. Paying attention to anthroponymy and homonymy, to the documented models of sponsorship, to the blood relations existing between spiritual parents and godchildren and to the reasons that gave rise to their choice.Universidad de Valladolid PID2024-159231NB-I0
Differences in Cardiovascular, Biochemical and Nutritional Parameters Between High- and Low-Altitude Winter Sports Athletes
No full textBackground/Objectives: High-altitude hypoxia may affect ECG readings, but it is unclear whether the “live-low–train-high” approach prevents these changes in winter sports
athletes. Methods: This cross-sectional study assessed cardiovascular parameters in
102 winter-sport athletes (mean age 20 ± 4 y; 57% women), divided by training altitude into
a high-altitude (HA) group (2500–3300 m, n = 70; skiers/snowboarders) and a low-altitude
(LA) group (738 m, n = 32; ice hockey/figure skaters). Mid-season assessments included
resting ECG, blood pressure, blood biochemistry, and three 24 h dietary recalls. Results: All
ECG parameters were physiological, and no significant differences (p < 0.05) were observed
in heart rate, PR interval, or QTc between groups. However, HA group exhibited higher
systolic blood pressure and a short QT interval. Lactate was significantly higher in HA
(p = 0.028). The HA diet contained more saturated fat (p < 0.001), cholesterol (p = 0.013),
magnesium (p = 0.003) and potassium (p = 0.001), whereas LA athletes consumed more
glucose (p = 0.024). In HA, total energy expenditure correlated positively (p ≥ 0.05) with
QRS (ρ = 0.52) and QT (ρ = 0.56), while heart rate correlated inversely with vitamin D
(ρ = −0.59). In LA, QTc showed strong inverse correlations with zinc (ρ = −0.62) and selenium (ρ = −0.85). Conclusions: This finding suggests that intermittent high-altitude
training did not alter ECG patterns when nutrient intake was adequate. High lactate level
and specific nutrient correlations point to a residual physiological load and a modulatory
role of electrolytes, B-vitamins, and vitamin D on cardiac repolarisation.High Council for Sports (CSD) - Spanish Ministry of Culture and Sport (Ref. 19/UPB/23)Instituto de Salud Carlos III / CIBEROBN / European Regional Development Fund (CIBEROBN CB12/03/30038
Utopia on Stage: The Libertarian Theater of Federico Urales and Florencio Sánchez in Spain and Río de la Plata at the Beginning of the 20th Century
No full textEste artículo analiza el papel del teatro dentro de los círculos anarquistas en España y el Río de la Plata a finales del siglo XIX y principios del XX, centrándose en las obras de Federico Urales y Florencio Sánchez. A partir del estudio de Ley de herencia (1902), de Urales, y ¡Ladrones! (1897) y Canillita (1902), de Sánchez, se exploran las conexiones entre el teatro y la difusión de ideales libertarios, así como el impacto de estas producciones en sus respectivos contextos sociopolíticos. Más allá del análisis textual, se considera la recepción y puesta en escena de estas piezas, evidenciando la interacción entre cultura y militancia anarquista.This article examines the role of theater within anarchist circles in Spain and the Río de la Plata at the turn of the 20th century, focusing on the works of Federico Urales and Florencio Sánchez. Through the analysis of Urales’ Ley de herencia (1902) and Sánchez’s ¡Ladrones! (1897) and Canillita (1902), the study explores the connections between theater and the dissemination of libertarian ideals, as well as the impact of these productions in their sociopolitical contexts. Beyond textual analysis, the article considers the reception and staging of these plays, highlighting the interaction between culture and anarchist activism
A persistent increase in gut permeability correlates with emotional dysregulation following maternal separation in male and female mice
No full textEarly life stress (ELS) significantly influences vulnerability to psychiatric disorders in adulthood. A widely used
preclinical model for studying ELS is maternal separation with early weaning (MSEW), which mimics early-life
neglect. This study evaluated the impact of ELS induced by MSEW on emotional behaviour, intestinal permeability, and neuroinflammatory markers in male and female mice. Our results show that MSEW increases anxietylike behaviours in adulthood, particularly in females, and exacerbates depression-like behaviours and anhedonia
in both sexes. Notably, increased intestinal permeability correlated with higher anxiety and depression-like responses, suggesting a crucial role of gut health in emotional regulation. These alterations were long-lasting,
indicating persistent effects on gut function following ELS. Additionally, MSEW animals exhibited higher hippocampal BDNF expression, particularly males. However, there were no significant differences in the long-term
survival of adult-born hippocampal cells, as indicated by BrdU+ labelling. Both sexes showed increased NF-κB
protein levels; however, only MSEW males exhibited TNF-α changes, suggesting a sex-specific regulatory
mechanism in response to chronic stress. This study highlights intestinal permeability as a key mechanism
linking ELS to emotional and behavioural dysregulation. By demonstrating a long-lasting increase in intestinal
permeability and its correlation with mood disorders, our findings extend the gut-brain axis hypothesis to ELS.
The inclusion of both sexes provides a more comprehensive understanding of sex-specific effects of early stress,
often overlooked in previous research.MCIN/AEI/10.13039/501100011033 (PID2020–114374RB-I00)Universidad de Málaga (B1–2022_05)Universidad de Málaga / CBUA (Open access)Secretaría General de Universidades, Investigación y Tecnología–Junta de Andalucía (POSTDOC21_00365)Instituto de Salud Carlos III (CD24/00041)Spanish Ministry of Science, Innovation and Universities (FPU22/

The Effects of Cardiopulmonary Fitness on Executive Functioning or Academic Performance in Students from Early Childhood to Adolescence? A Systematic Review
No full textBackground: Cardiovascular fitness has been proposed as a key factor influencing executive functioning and academic performance during childhood and adolescence. However,
the extent and consistency of this relationship remain unclear across diverse populations
and educational contexts. This systematic review aimed to evaluate whether cardiovascular fitness, particularly measured through VO2max, is consistently associated with
improvements in executive function and academic performance among students from
early childhood to adolescence. Methods: A systematic search of PubMed, Web of Science,
SPORTDiscus, and ProQuest Central was conducted up to 15 November 2022. Studies
were included if they examined correlations between VO2max and cognitive or academic
outcomes in students from preschool to high school. Methodological quality was assessed
using the MINORS checklist. Results: Out of 271 identified studies, 12 met all inclusion
criteria. Evidence suggests that higher VO2max is generally associated with improved
executive function domains such as attention, working memory, and inhibitory control,
as well as academic performance indicators including mathematics and reading scores.
Neurophysiological studies also indicate links between cardiovascular fitness and brain
structure/function. However, the strength and specificity of these associations vary across
studies due to methodological differences, limited sample diversity, and inconsistent control for confounders. Conclusions: Cardiovascular fitness appears to have a positive, albeit
complex, relationship with cognitive function and academic performance in youth. Future
research should adopt longitudinal and experimental designs to clarify causal pathways
and consider moderating factors such as sex, age, and psychosocial variables
Complexity and Variability in the Translation of Literature into Easy Language
No full textEn el ámbito de la traducción accesible, la modalidad de la
Lectura Fácil (LF) suscita una creciente atención académica
y científica internacional. La LF, dirigida en primera
instancia a personas con problemas de comprensión lectora,
prolifera en textos de todos los géneros y temáticas, desde
los jurídicos hasta los patrimoniales y los literarios. Este
aumento de los materiales traducidos a LF según distintas
directrices (en España, AENOR 2018; IFLA 2012; Inclusion
Europe 2009), así como de publicaciones científicas que
presentan su estado de la cuestión (Lindholm y Vanhatalo
2021; Maaß 2020), deja cada vez más patente una tendencia
a la interpretación subjetiva de las normas, que resulta en
traducciones heterogéneas. Pese a los avances recientes,
todavía falla la comprobación empírica de las pautas de
simplificación y el estudio individualizado de las necesidades
de los usuarios (Toribio Camuñas y Jiménez Hurtado 2022), y
son escasas las iniciativas que pretenden crear una definición
epistemológica de la LF y describir su proceso traductor. En
este artículo se presentan los resultados de un estudio de caso
de varios fragmentos de los clásicos literarios Don Quijote de
la Mancha y El Principito en LF, en sus versiones traducidas
según diferentes normativas y directrices (de Cervantes
Saavedra 1605/2015; de Cervantes Saavedra 1605/2019; de
Saint-Exupéry 1943/2018; de Saint-Exupéry 1943/2019). Los
datos obtenidos refrendan la hipótesis de partida y reflejan
la profunda heterogeneidad de los textos meta, producida
por las carencias de las directrices de simplificación, a la
vez que ponen de manifiesto las dificultades que plantea la
traducción del género literario a LF. Estos resultados apuntan,
a su vez, a la necesidad de avanzar hacia una investigación
empírica y descriptiva que aspire a crear traducciones que,
dejando espacio para el disfrute de la lectura, conserven un
cierto grado de homogeneidad, teniendo en cuenta que este
fenómeno es un parámetro del acceso al conocimiento.Easy Language (EL) is experiencing increasing academic and scientific international attention
within the field of accessible translation. EL, primarily aimed at people with reading comprehension
difficulties, proliferates now across all genres and themes, from legal to cultural heritage and literary
texts. The rising number of materials translated to EL with the help of different guidelines (in Spain,
AENOR 2018; IFLA 2012; Inclusion Europe 2009), as well as of scientific publications presenting their
state of the art (Lindholm y Vanhatalo 2021; Maaß 2020), increasingly highlights a trend towards
subjective interpretation of the norms, which in turn leads to heterogeneous translations. Despite
recent advances, empirical validation of simplification guidelines and individualized study of users’
needs (Toribio Camuñas y Jiménez Hurtado 2022) are still lacking, and there are few initiatives aimed
at creating an epistemological definition of EL and describing its translation process. This article
presents the results of a case study of several excerpts from the literary classics Don Quixote and
The Little Prince in Easy Spanish, in their versions translated according to different standards and
guidelines (de Cervantes Saavedra 1605/2015; de Cervantes Saavedra 1605/2019; de Saint-Exupéry
1943/2018; de Saint-Exupéry 1943/2019). The data obtained support the initial hypothesis and reflect
the deep heterogeneity of the target texts, produced by the shortcomings of the guidelines, while
also highlighting the challenges posed by the translation of the literary genre to Easy Spanish. These
results, in turn, point to the need to move towards empirical and descriptive research that aspires
to create translations which, while allowing for the enjoyment of reading, maintain a certain degree
of homogeneity, considering that this phenomenon is a parameter of access to knowledge.MCIN/AEI/10.13039/501100011033 - FPU20/01379 - FSE (PID2020-118775RB-C21
