En el vientre de la yihad (2017), de Alexandra Gil. El préstamo léxico yihad y sus connotaciones semánticas y pragmáticas como metáfora
No full textProducción CientíficaEl presente estudio se centra en el análisis del préstamo léxico yihad en la obra En el vientre de la yihad (2017), de Alexandra Gil, partiendo de Lakoff y Johnson y de Steen. La investigación se centra en el análisis de las metáforas y connotaciones vinculadas con esa realidad y sus posibles imágenes cognoscitivas. De esta manera, los resultados muestran que el dominio fuente yihad se encuentra asociado a dominios meta como geopolítica, estigma sociofamiliar, violencia y negocio, entre otros. Estos resultados influyen en la creación y recreación de imágenes cognoscitivas hacia el islam desde una perspectiva occidental y responden a una visión belicista del mismo

ÁFRICA EN LA ENSEÑANZA UNIVERSITARIA. MÉTODOS Y PROPUESTAS PARA APROXIMAR AL ESTUDIANTADO A LA REALIDAD AFRICANA
No full textÁfrica, continente de enorme diversidad cultural, lingüística y social, ha sido históricamente reducida en la academia europea a visiones simplificadoras marcadas por el eurocentrismo. Frente a ello, este texto propone una revisión profunda de su lugar en la enseñanza universitaria, resaltando la necesidad de integrar los estudios africanos de forma transversal y rigurosa. Reconocer la pluralidad africana no solo corrige una injusticia histórica, sino que enriquece la producción de conocimiento, ampliando la mirada crítica, global e inclusiva del alumnado

Participatory Methodologies for Addressing School Bullying: An Overview and Methodological Guidelines
No full textProducción CientíficaBullying is not a dyadic interaction between victim and perpetrator, but a relational phenomenon involving multiple group networks: those who exercise physical, psychological, or symbolic violence; those who encourage it; those who suffer it; and those who, while aware of it, remain on the sidelines. Preventing bullying, or stopping it once it emerges, requires undermining the support base that sustains it: no one should play the role of cheerleader, and those who remain passive must become involved in defending those targeted. It is also necessary to foster in those who are bullied the strength and capacity to confront the situation. From a Freirean perspective, this implies weaving alliances between those who are kindred and those who are different, and even with outsiders, to oppose those who act antagonistically. Such a task demands debate, reflection, and the collective formulation of measures among the diverse group realities in schools, given that bullying is grounded in the refusal to recognize certain others as part of “us”, though we are all “others” to one another. This article sets out arguments for the need to address these diverse group realities and presents the phases and main contents of a participatory process for designing and implementing a School Coexistence Plan, drawing on the Participatory Construction of Peaceful Coexistence method as a framework for addressing bullying
A green strategy to transform pineapple peel into biobutanol includes microwave pretreatment and in-situ butanol recovery.
No full textProducción CientíficaPineapple peel, a residue rich in free sugars, can be hydrolyzed under mild conditions. Here, direct enzymatic hydrolysis (EH) of pineapple peel in the presence of Cellic CTec 2 at only 5 FPU g-¹ of pineapple peel dry mass yielded a hydrolysate containing 50.3 g L-¹ total sugars, but which was poorly fermentable. Pretreating the pineapple peel with
microwave (MW) at 130 °C in the presence of water provided a fermentable residue containing 43.7 g L-¹ total sugars that generated 8.4 g L-¹ butanol. Thus, thermal treatment helped to overcome fermentation hindrance. Treating the pineapple peel with MW at 130 °C followed by EH at enzyme loading of 5 FPU g-1 DM gave a fermentable hydrolysate containing 50.6 g L-¹ total sugars. Fermenting this hydrolysate in a bioreactor with in-situ butanol recovery by gas stripping with a pulse of glucose/fructose solution increased the butanol concentration to 9.8 ± 0.4 g L-¹. Overall, microwave pretreatment was essential to obtain a fermentable hydrolysate from pineapple peel, while gas stripping facilitated butanol removal during fermentation.Spanish Ministry of Science, Innovation and Universities and the European Regional Development Fund (project PID2020-115110RB-I00/AEI/10.13039/501100011033 and project PID2023-147967OB-I00 / MCIU /AEI /10.13039/501100011033 / FEDER, EU).

Audit Committee Networks and Audit Fees: A European Analysis
No full textProducción CientíficaThis study investigates the association between audit committee member networks and audit fees in a sample of 225 publicly traded firms from eight European countries between 2005 and 2020. Using social network analysis, we find that director interconnections—established through overlapping board memberships—are associated with audit fees. Our findings reveal an extensive, yet fragmented director network, where higher centrality positions correlate with increased audit fees. This suggests that director connections strengthen the demand for audit effort, leading to higher audit fees. Furthermore, we show that director centrality moderates the positive relationship between firm complexity, financial risk, and board independence with audit fees.Ministerio de Ciencia, Innovación y Universidades (MICIU) / Agencia Estatal de Investigación (AEI): PID2023-150140NA-I00 y PID2024-155796NB-I00 (MICIU/AEI/10.13039/501100011033 / FEDER, EU)Universidad de Valladolid / Banco Santander: contrato predoctoral UVa de Ruth García Cobo (CONTPR-2022-439)Open access funding provided by FEDER European Funds and the Junta De Castilla y León under the Research and Innovation Strategy for Smart Specialization (RIS3) of Castilla y León 2021-2027
Boosting Arthrospira platensis metabolism during biogas upgrading via carbon coated iron-based nanoparticle addition
No full textProducción CientíficaCarbon-coated iron-based nanoparticles have demonstrated a significant potential to enhance the performance of
biological processes, particularly microalgal cultivation. In this study, the effect of two types of commercially
available iron-based nanoparticles, namely CALPECH and SMALLOPS, was evaluated on Arthrospira platensis
metabolism during biogas upgrading in batch cultures. Both nanoparticles enhanced CO2 capture, O2 production,
cyanobacterial growth and phycocyanin synthesis across all tested concentrations. However, the highest
phycocyanin content (180 mg⋅g 1) was reached by the addition of CALPECH nanoparticles at 100 mg⋅L 1.
Further experiments under stress conditions, including increased light intensity (300 and 600 μmol⋅m 2⋅s 1) and
salinity (0.1–0.5 M NaCl) confirmed the beneficial effects of CALPECH. At 600 μmol⋅m 2⋅s 1 CALPECH nano-
particles enhanced biomass productivity and increased CO2 capture by 33 % while maintaining phycocyanin
content at 178 mg⋅g 1. Moreover, the addition of 100 mg⋅L 1 of CALPECH nanoparticles at 0.1 M NaCl slightly
improved biogas upgrading performance and increased phycocyanin content to 192.7 mg⋅g 1. In this context,
increasing salinity to 0.5 M caused stress in Arthrospira platensis cells, reducing photosynthetic efficiency
regardless of nanoparticle addition. These outcomes highlight the potential of carbon-coated iron-based nano-
particles to improve Arthrospira platensis growth and pigment production, which would ultimately increase the
techno-economic feasibility of photosynthetic biogas upgradin
Expresión, intimidad y temporalidad en la interpretación musical
No full textThis dissertation undertakes a philosophical study of musical interpretation, conceived as a phenomenon where expression, intimacy, and temporality converge. Interpretation is approached not as a purely technical activity but as a practice in which work and performer mutually shape each other. The aim is to trace the historical emergence of this notion, to distinguish it from related concepts such as execution or version, and to reflect on its meaning in contemporary musical life.
The first part reconstructs the genealogy of interpretation in Western music. Beginning with Rousseau and his emphasis on expression, the thesis shows how music gradually became associated with inner subjectivity, until Romanticism consolidated it as a language of intimacy. Schopenhauer’s metaphysical conception of music and Liszt’s transformation of virtuosity into expressive performance illustrate the consolidation of an art of autonomous works, in which the performer plays a central role. Music thus ceased to be mere execution of sounds and became mediation between subjectivity and a cultural heritage regarded as common property.
The second part addresses the long-standing conflict between composer and performer. Against objectivist views, which subordinate performance to fidelity to the score, and against subjectivist positions, which dissolve the identity of the work into performer freedom, the thesis argues for a dialectical approach. In this perspective, work and performer co-determine each other in the act of performance: the score serves as mediation, yet meaning arises in the living moment, marked by temporality and open to creativity. Improvisation and play are not deviations but essential aspects of the interpretative act.
The conclusions emphasize that interpretation is a process in which repetition and difference, technique and subjectivity, tradition and novelty intertwine. Far from being either deviation or reproduction, it constitutes a kairological space where music comes alive and is renewed with each realization. This opens paths for further inquiry: the relationship between performance and recording, the potential of analogical hermeneutics as a philosophical framework, and the challenges posed by artificial intelligence to musical practice. Ultimately, the dissertation argues for understanding music not only as an aesthetic object but as a living experience of expression and shared meaning.Esta tesis doctoral explora filosóficamente la noción de interpretación musical, entendida como un fenómeno en el que confluyen expresión, intimidad y temporalidad. Más que un mero ejercicio técnico, la interpretación se plantea como una práctica en la que la obra y el intérprete se configuran mutuamente. El propósito ha sido examinar cómo surge históricamente esta noción, cómo se diferencia de conceptos próximos como ejecución o versión y qué sentido tiene en la práctica musical contemporánea.
La primera parte del trabajo reconstruye el nacimiento de la interpretación en la tradición occidental. Partiendo de Rousseau y su énfasis en la expresión, se muestra cómo la música fue vinculándose progresivamente con la interioridad del sujeto, hasta consolidarse en el Romanticismo como lenguaje de la intimidad. Schopenhauer, con su concepción metafísica de la música, y figuras como Liszt, con su transformación del virtuosismo en experiencia expresiva, encarnan el paso hacia un arte de obras autónomas en el que el intérprete adquiere un papel central. La música dejó de ser solo ejecución de sonidos para convertirse en mediación entre la subjetividad y un legado cultural entendido como patrimonio común.
La segunda parte aborda el conflicto entre compositor e intérprete, eje de las discusiones filosóficas más recientes. Frente a las visiones objetivistas, que reducen la interpretación a fidelidad a la partitura, y frente a las subjetivistas, que diluyen la identidad de la obra en la libertad del intérprete, la tesis defiende un enfoque dialéctico. En él, obra e intérprete se co-determinan en el instante de la performance: la partitura actúa como mediación, pero el sentido emerge en el acto vivo, atravesado por la temporalidad y abierto a la creatividad. La improvisación y el juego no aparecen como desviaciones, sino como rasgos constitutivos de la acción interpretativa.
Las conclusiones subrayan que la interpretación es un proceso en el que se entrelazan repetición y diferencia, técnica y subjetividad, tradición y novedad. Más que un desvío de la obra o una simple reproducción, constituye un espacio kairológico donde la música cobra vida y se renueva en cada aparición. De ahí se derivan futuras líneas de investigación: la relación entre interpretación y grabación, la utilidad de la hermenéutica analógica como marco filosófico y los retos que plantea la inteligencia artificial a la práctica musical. En definitiva, la tesis propone pensar la música no solo como objeto estético, sino como experiencia viva de sentido compartido.Escuela de DoctoradoDoctorado en Filosofí
