Evaluación de la competencia global docente desde una mirada intercultural y de valores humanos para la inclusión
No full textEsta tesis surge con la intención de contribuir a la formación y evaluación del profesorado para que pueda atender los desafíos actuales provocados por la globalización. Estos desafíos tienen que ver con cuestiones ambientales, económicas, sociales y culturales, haciendo hincapié en las dos últimas. Para poder diseñar planes formativos que permitan al profesorado desarrollar y mejorar su competencia global docente, es necesario definir con claridad dicha competencia y explorar metodologías para su evaluación. Nuestro objetivo principal es elucidar qué se entiende por competencia global docente y evaluar que variables influyen en ella. La metodología utilizada se basa en un enfoque de métodos mixtos que conjuga investigación cuantitativa y cualitativa. El diseño es explicativo secuencial donde en la primera fase cuantitativa se analizan los resultados y se usan para construir la fase cualitativa. En la segunda fase centrada en técnicas cualitativas se busca recoger opiniones detalladas de los participantes que ayuden a explicar con más detalle los resultados cuantitativos. Tras una exhaustiva revisión de literatura, se plantea una definición de competencia global general y un modelo de competencia global docente. Además, se identifican distintos instrumentos que permiten evaluar dichas competencias. Se validan al castellano dos de las encuestas identificadas y los resultados de su análisis y de las entrevistas permiten identificar las variables que influyen en la competencia global docente y su enseñanza. Las variables identificadas tienen que ver con aspectos intrapersonales como: los conocimientos, la ideología, los valores de universalismo y apertura al cambio, la disposición y conciencia crítica; aspectos contextuales como: el apoyo institucional o de las Organizaciones No Gubernamentales para el Desarrollo (ONGD), el proyecto educativo de centro (PEC) y el trabajo en red. Por último, en los aspectos relacionados con la práctica lo que más destaca es la diferencia entre los docentes de distintas especialidades, donde las ciencias experimentales muestran una mayor dificultad para conectar los temas o contenidos de la educación global con el currículo de estas asignaturas. Se concluye que es necesaria una formación docente en educación global y una mayor investigación sobre la competencia global docente.This thesis arises with the intention of contributing to teacher training and evaluation in order to meet the current challenges brought about by globalisation. These challenges relate to environmental, economic, social and cultural issues, with an emphasis on the last two. In order to design training plans that enable teachers to develop and improve their global teaching competence, it is necessary to clearly define this competence and explore methodologies for its assessment. Our main objective is to elucidate what is meant by global teaching competence and to assess which variables influence it. The methodology used is based on a mixed methods approach combining quantitative and qualitative research. The design is sequential explanatory where in the first quantitative phase the results are analysed and used to construct the qualitative phase. The second phase focuses on qualitative techniques and seeks to collect detailed opinions from participants to help explain the quantitative results in more detail. Following an exhaustive literature review, a definition of general global competence and a model of global teacher competence are proposed. In addition, different instruments for assessing these competencies are identified. Two of the identified surveys are validated in Spanish, and the results of their analysis and the interviews allow us to identify the variables that influence global teaching competence and its teaching. The variables identified have to do with intrapersonal aspects such as: knowledge, ideology, values of universalism and openness to change, willingness and critical awareness; contextual aspects such as: institutional support or support from Non-Governmental Development Organisations (NGDOs), the school's educational project (PEC) and networking. Finally, in the aspects related to practice, what stands out most is the difference between teachers of different fields, where experimental sciences show greater difficulty in connecting the themes or contents of global education with the curriculum of these subjects. It is concluded that there is a need for teacher training in global education and for more research on global competence in teaching

Estudio de la extracción de compuestos fenólicos de residuos agrarios de mazorca de maíz mediante la metodología de superficie de respuesta
No full textCorn is presently one of the most expensively cultivated cereals worldwide, resulting in significant agricultural solid residues. The corncob waste is considered a by-product due to its phenolic fraction rich in phenolic acids and flavonoids that could be substitute synthetic functional additives in various food and pharmaceutical applications. This study has been focused on investigating different extraction processes and operating conditions to recover the phenolic fraction from corncob waste, followed by an identification study to valorise the final extracts. The experiments were conducted using bath extraction with rotary agitation and ultrasound-assisted extraction. The solvent was ethanol, water, and various ethanol-water mixtures. Ultrasonication has been more effective than rotatory agitation, ensuring higher extraction yields in a much shorter contact time. The presence of kaempferol, p-coumaric acid and ethyl-ferulate has been identified in the phenolic profile of all extracts from the treatment of corncob waste with ethanol solvents. The response surface methodology with a Box-Behnken desing (BBD) has been employed to analyse the combined effect of contact time, solid waste amount and ethanol fraction in the solvent on the extraction efficiency. Kinetic experiments were also performed with the optimal solvent selected from the BBD to examine maximising extraction of p-coumaric acid, kempferol and ethyl-ferulate
Confrontation as a banner. Analysis of Vox’s political discourse in the 2021 Catalan elections
No full textLa campanya electoral de les eleccions al Parlament de Catalunya del 2021, primera
convocatòria electoral catalana després de les eleccions excepcionals convocades pel
president Mariano Rajoy el 2017, va introduir una novetat important en el mapa polític
català: la participació de Vox en els comicis autonòmics catalans. Aquesta novetat es va
sumar al context insòlit de l’organització d’unes eleccions durant la pandèmia de la
COVID-19. En aquesta recerca s’analitza el contingut discursiu que utilitza la formació de
dreta radical Vox per afrontar aquests comicis, a partir de la classificació dels principals
components del seu discurs polític en els mítings realitzats durant la campanya i al
programa electoral. S’arriba a la conclusió que els continguts discursius utilitzats durant
la campanya per Vox es basen, principalment, en la confrontació amb el moviment
independentista català, i deixen de banda altres temàtiques com la immigració
o la confrontació amb el moviment feminista.The electoral campaign of the 2021 Catalan elections, which were the first Catalan
elections to be called after the exceptional elections which had been called by Spanish
President Mariano Rajoy in 2017, introduced an important novelty in Catalan politics: the
participation of the Vox party in the Catalan regional elections. This newness compounded
the unusual context of organizing an election during the COVID-19 global pandemic. This
research analyzes the discursive content used by the radical right-wing party Vox to
approach these elections. Specifically, to carry out this analysis, the main components
of Vox’s political discourse in the meetings held during the campaign, and the principal
components of its electoral program, are classified by means of content analysis. The
main conclusion is that Vox uses confrontation with the Catalan independence movement
as its primary campaign message, leaving aside other characteristic issues of its discourse
such as immigration or confrontation with the feminist movement

No full textPóster presentado en: XXVII Encontro Luso Galego de Química, 22-24 de novembro 2023, Porto (Portugal).Theonion (AlliumcepaL.) processing industry generates substantial inedible wastes which constitute an environmental risk. Nevertheless, these wastes could be valorized to obtain bioactive compounds with antioxidant, anticancer and antidiabetic properties [1]. For this purpose, subcritical water extraction (SWE) offers an eco-friendly approach by using pressurized hot water (100-374ºC) with unique properties as solventThis work also had the financial support from the Spanish Agencia Estatal de Investigación [PID2020-116716RJ-I00/AEI/10.13039/501100011033]
Caracterización e idoneidad de la utilización de triturado de palas de aerogenerador en la producción de hormigón
No full textComunicación presentada en: 2nd International Córdoba Eco-Concrete Conference (ICECC) 2023, durante los días 5-7 de julio en Córdoba (España)Muchos de los primeros aerogeneradores están acercándose al final de su vida útil. Así, sus palas deben ser
desmanteladas, necesitando soluciones para su reciclaje innovadoras, por los materiales que la componen.
Esta solución aborda su tratamiento mediante corte y machaqueo, generando así Triturado de Pala de
Aerogenerador (TPA), válido para su incorporación en hormigón. Se realizó un diseño del hormigón
específico para contenidos de TPA de hasta el 6% vol., para asegurar su adecuado comportamiento.
Además, se desarrolló un proceso de mezcla con 5 etapas con correcciones de plastificante según el
porcentaje de residuo añadido. Al añadir TPA al hormigón se obtuvieron mejores resultados en capacidad
portante, aunque se produjo una leve disminución en resistencia a compresión. Este enfoque ofrece una
solución válida para el reciclaje de palas de aerogeneradores.This research work was supported by the Spanish Ministry of Universities, MICINN, AEI, EU, ERDF and NextGenerationEU/PRTR [grant numbers PID2023-146642OB-I00; 719 10.13039/501100011033; TED2021-129715 B–I00]; the Junta de Castilla y León (Regional Government) and ERDF [grant number UIC-231; BU033P23
Effects of a Functional Product Derived from Beet Molasses Vinasse on Blood Pressure and Endothelial Function in Hypertensive Rats
No full textComunicación presentada en: The 4th International Electronic Conference on Foods 2023, durante los días 15-30 de octubre de forma online.A functional product obtained from beet molasses vinasse (V) was supplemented to hypertensive rats (SHR) to assess its preventive effects against high blood pressure and endothelial dysfunction. Fifteen potential bioactive compounds (including phenolic acids, flavonoids and terpenoids, and glycosylated compounds) were identified and quantified in V by HPLC-MS. The most notable finding of the study was that the blood pressure values remained similar to those at the beginning of the study in the SHR+V group. At the same time, they increased progressively in the SHR control group, reaching a significant difference of 16% (p < 0.05) after 5 weeks of supplementation. Quantitative PCR and Western blot analyses of the aorta demonstrated that V ingestion by hypertensive rats led to decreased ACE mRNA levels and higher SOD2 and eNOS gene expression via promotion of Nrf2 transcriptional activity and down-regulation of the NF-κB pathway. These results are associated with an increased antioxidant, anti-inflammatory, and vasodilatory response. In conclusion, the intake of vinasse-derived products could mitigate hypertension and associated endothelial dysfunction.This research was funded by the Junta de Andalucía and the European Union (FEDER), grant number PY18-CO-0047 (AZUBIOACT project), with the collaboration of the Azucarera del Guadalfeo S.A.

Valorization of onion skin wastes using subcritical water: flavonoids and pectin recovery
No full textComunicación oral presentada en: 2nd Greenering International Conference 2023, celebrada durante los días 21-23 de marzo en Valladolid (España)Onion skin wastes (OSW) represent around 10% of the total onion production and end up in landfills because they are not suitable for human consumption or animal feeding. Nevertheless this non-edible brown skin and external layers of onions are rich and phenolic compounds, mainly flavonoids such as quercetin and derivatives, which are high-added valye natural antioxidants. Additionally, onion skin has gained attention as a good source of pectin. Pectin, a complex polysaccharide composed by uronic acids (66.4%) and neutral sugars (galactose, arabinose, xylose, mannose, glucose or rhamnose) in variable composition, is the major structural component onion cell walls (42,4%). Considering that according to FAO, 2020 onion worldwide production was 104 Mt, there is a great potential for the calorization of the OSW through the recovery of flavonoids and pectin.Agencia Estatal de Investigación [PID2020‐116716RJ‐I00, PID2019‐104950RB‐I00, TED2021-129311B-I00] and Junta Castilla y León (JCyL) and the European Regional Development Fund [BU301P18, BU050P20
