Recent Advances and Potential Applications of Atmospheric Pressure Cold Plasma Technology for Sustainable Food Processing
Get PDFIn a circular economy, products, waste, and resources are kept in the system as long as
possible. This review aims to highlight the importance of cold plasma technology as an alternative
solution to some challenges in the food chain, such as the extensive energy demand and the hazardous
chemicals used. Atmospheric cold plasma can provide a rich source of reactive gas species such as
radicals, excited neutrals, ions, free electrons, and UV light that can be efficiently used for sterilization
and decontamination, degrading toxins, and pesticides. Atmospheric cold plasma can also improve
the utilization of materials in agriculture and food processing, as well as convert waste into resources.
The use of atmospheric cold plasma technology is not without challenges. The wide range of
reactive gas species leads to many questions about their safety, active life, and environmental impact.
Additionally, the associated regulatory approval process requires significant data demonstrating
its efficacy. Cold plasma generation requires a specific reliable system, process control monitoring,
scalability, and worker safety protections
Rock Magnetism of Lapilli and Lava Flows from Cumbre Vieja Volcano, 2021 Eruption (La Palma, Canary Islands): Initial Reports
Get PDFWe present initial rock magnetic results for both lava flows and lapilli produced by the 2021
eruption of the Cumbre Vieja, La Palma (Canary Islands). Samples were taken during the eruption to
minimize early alteration and weathering of the rocks and tephra. Standard procedures included
progressive alternating field and thermal demagnetization, hysteresis curves, thermomagnetic experiments, progressive acquisition of isothermal remanent magnetization (IRM), and First-Order Reversal
Curves (FORCs). Overall, our observations, including low to medium unblocking temperatures,
isothermal remanent magnetization to 1 Tesla, and the abundance of wasp-waist hysteresis loops,
strongly suggest the presence of Ti-rich titanomagnetites as the main remanence carriers in both lava
flows and lapilli, in addition to some hematite as well. Whereas the former has been directly seen
(SEM), hematite is elusive with nonmagnetic-based methods. Rock magnetic data, on a Day plot, also
reveal that the magnetic grain size tends to be larger in the lava flows than in the lapilli.This research was funded by Agencia Estatal de Investigación, Spain, grant no. PID2019-105796GB-00/AEI/10.13039/501100011033
Developing and acquiring critical literacy skills in early childhood education
Get PDFLos objetivos de esta investigación se centran, por una parte, en evaluar las competencias de literacidad crítica de un grupo-aula de alumnos/as españoles de Educación Infantil (n = 11) antes y después de una intervención docente sobre la pobreza y, por otra, evidenciar la importancia de adquirir actitudes comprometidas y responsables para la comprensión y resolución de problemas sociales globales. La investigación se desarrolla desde un enfoque cualitativo y cuantitativo-descriptivo, y aplica una escala de observación, diseñada ad hoc, y dos grupos focales como instrumento y técnica de recolección de datos. Los resultados obtenidos demuestran la contribución de la integración curricular de problemas sociales globales a la adquisición de competencias críticas y al desarrollo del pensamiento social en Educación Infantil. El desarrollo de competencias de literacidad crítica desde edades tempranas añade implicaciones importantes para la educación de una ciudadanía crítica, capaz de pensar y actuar ante las desigualdades sociales.This research aims to evaluate the critical literacy skills of a classroom group of Spanish pre-school students (n = 11) before and after a teaching intervention on poverty and, on the other hand, to demonstrate the importance of acquiring committed and responsible attitudes for the understanding and resolution of global social problems. The research is developed from a qualitative and quantitative-descriptive approach and applies an observation scale, designed ad hoc, and two focus groups as an instrument and data collection technique. The results obtained demonstrate the contribution of the curricular integration of global social problems to the acquisition of critical competencies and the development of social thinking in Early Childhood Education. The development of essential competencies of literacy from an early age adds important implications for the education of critical citizenship, capable of thinking and acting in the face of social inequalities.Esta investigación ha sido realizada al amparo del proyecto Educación para el futuro y esperanza en la democracia.

Intellectual property on the research results of university teaching staff and the obligation of open access following the science law reform: paradigm shift?
Get PDFEn septiembre de 2022 se ha reformado la Ley 14/2011 de la Ciencia, la Tecnología y la Innovación, en cuestiones que tienen que ver con la propiedad intelectual de las obras y otros resultados que produce el profesorado al desarrollar su actividad de investigación. Ahora, el artículo 35 se ocupa de la titularidad de los derechos sobre los resultados de las actividades de investigación del personal de las universidades y otras entidades públicas, que antes se regulaba en la Ley de economía sostenible. También se ha reformado el mandato del artículo 37, sobre puesta a disposición del público en acceso abierto de los resultados de investigación. Con este trabajo se analiza cómo afectan ambos preceptos al profesorado universitario. Se trata de aclarar, entre otras cuestiones, si la nueva regulación atribuye o no con carácter general los derechos de explotación sobre las obras del profesorado a las universidades en las que desarrolla su actividad investigadora, si son las universidades o el profesorado quienes deben cumplir con el mandato de acceso abierto, y en qué medida el artículo 37 deja de ser una norma dispositiva. Se concluye que no hay atribución a las universidades de los derechos de explotación sobre las obras resultado de la investigación, sino que se conservan por el profesorado en aplicación de la Ley de propiedad intelectual a la que remite el artículo 35, 2 de la Ley de la ciencia. Que el artículo 37 regula una nueva obligación de depósito de las publicaciones y datos en repositorios, para el profesorado y otro personal de investigación de las universidades y otras entidades públicas. Y que los sujetos comprometidos a poner a disposición del público los resultados de investigación en abierto, cuando lo establecen las condiciones de las convocatorias de ayudas públicas con las que se han financiado, son los investigadores e investigadoras.In September 2022, the Law 14/ 2011 on science, technology and innovation has been reformed
in matters regarding the intellectual property related the professors´works and other results produced in
the course of their research activities. Now article 35 deals with right ownership of research activities
outcomes coming from university staff and other public entities, which was previously regulated in the
Sustainable Economy Law. The article 37 former mandate compellig to make research results available to
the public in open access has also been reformed. This paper analyzes how both precepts affect university
faculty.
The aim is to assess, among other questions, whether or not the new regulation generally attributes the
intellectual property rigths exploitation to the universities where teaching staff carry out their research
activity; And in addition, knowing who is to comply with the open access mandate, the universities or the
teaching staff and to what extent article 37 ceases to be a dispositive norm. It is concluded that there is
no attribution to universities of rights explotation on works resulting from the research, but instead they are kept by teachers in application of the Law on Intellectual Property to which article 35, 2 of the Law of
Science refers. Besides, article 37 regulates a new obligation for the teaching staff and other research
personnel of the universities, consisting in the deposit of publications and data in repositories. What is
more, the subjects committed to making the results of open research available to the public are the
researchers, when the conditions of the calls for public grants with which they have been financed

Reconstruyendo la acción tutorial del maestro en tiempos de incertidumbre: hacia un modelo analítico desde el cuidado
No full textTrabajo presentado en: XXIX Coloquio AFIRSE Portugal
e Instituto de Educación de Lisboa, 9 al 11 de febrero de 2022.El cuidado se ha instalado en educación desde tres ejes claves de desarrollo estrechamente
interconectados: 1) la naturaleza relacional del conocimiento educativo y sus implicaciones para las acciones
educativas interpersonales, profesionales e institucionales; 2) la relación educativa como práctica
esencialmente ética y que posibilita el desarrollo moral en los educandos y las comunidades educativas; y 3) la
formación de los profesionales de la educación y su construcción de la identidad profesional. De este modo,
desde la investigación educativa el cuidado ha presentado un especial impacto en ámbitos como la familia, el
currículum escolar o la educación en valores, enriqueciendo el debate educativo, científico y profesional sobre
temas como civismo y ciudadanía, equidad y género, sostenibilidad y medio ambiente, y profesionalidad y
competencia.
El trabajo se fundamenta en una revisión de los discursos y prácticas sobre el cuidado en el ámbito educativo
con el objetivo de reconsiderar los referentes principales y, en especial, una de las intervenciones educativas
en las que se presume un alto potencial de impacto: la acción tutorial. Atendiendo a la naturaleza transdisciplinar
del fenómeno del cuidado, se identifican los modelos teóricos más trabajados y consolidados en el campo
sociosanitario para explorar la transferencia teórica al campo socioeducativo y vertebrar con criterio los estudios
y trabajos principales en educación. Se ilustra cómo el cuidado se presenta como un analizador de la cultura
profesional en el campo de la orientación educativa y la tutoría y como un catalizador de sinergias que resignifica
perspectivas y programáticas educativas.
Los resultados identifican resonancias y convergencias del cuidado educativo con ciertos modelos teóricos de
orientación y tutoría y definen líneas de trabajo para profundizar en los sentidos y significados de la acción
tutorial de los profesionales de la educación. También atraviesa los criterios de excelencia profesional desde
las implicaciones de una educación en y para el cuidado, señalando las oportunidades para una reconstrucción
de la praxis profesional de los tutores en sus comunidades educativas de referencia. La sensibilización que
supone el fenómeno del cuidado se atisba como una alternativa para interrogar el pensamiento y la acción
educativos en nuestras sociedades contemporáneas
Molecular Phylogeny Reveals the Past Transoceanic Voyages of Drywood Termites (Isoptera, Kalotermitidae)
Get PDFTermites are major decomposers in terrestrial ecosystems and the second most diverse lineage of social insects. The Kalotermitidae form the second-largest termite family and are distributed across tropical and subtropical ecosystems, where they typically live in small colonies confined to single wood items inhabited by individuals with no foraging abilities. How the Kalotermitidae have acquired their global distribution patterns remains unresolved. Similarly, it is unclear whether foraging is ancestral to Kalotermitidae or was secondarily acquired in a few species. These questions can be addressed in a phylogenetic framework. We inferred time-calibrated phylogenetic trees of Kalotermitidae using mitochondrial genomes of ∼120 species, about 27% of kalotermitid diversity, including representatives of 21 of the 23 kalotermitid genera. Our mitochondrial genome phylogenetic trees were corroborated by phylogenies inferred from nuclear ultraconserved elements derived from a subset of 28 species. We found that extant kalotermitids shared a common ancestor 84 Ma (75–93 Ma 95% highest posterior density), indicating that a few disjunctions among early-diverging kalotermitid lineages may predate Gondwana breakup. However, most of the ∼40 disjunctions among biogeographic realms were dated at <50 Ma, indicating that transoceanic dispersals, and more recently human-mediated dispersals, have been the major drivers of the global distribution of Kalotermitidae. Our phylogeny also revealed that the capacity to forage is often found in early-diverging kalotermitid lineages, implying the ancestors of Kalotermitidae were able to forage among multiple wood pieces. Our phylogenetic estimates provide a platform for critical taxonomic revision and future comparative analyses of Kalotermitidae.We thank the DNA Sequencing Section and the Scientific Computation and Data Analysis Section of the Okinawa Institute of Science and Technology Graduate University, Okinawa, Japan, for assistance with sequencing and for providing access to the OIST computing cluster, respectively.

Does knowledge influence visual attention? A comparative analysis between archaeologists and naïve subjects during the exploration of Lower Palaeolithic tools
Get PDFThe role of experience during the exploration of lithic artefacts can be been investigated through multiple approaches. Knowledge can influence visual perception of the environment, whilst action “affordances” can be processed at the first sight of an object. In this study, we used eye tracking to analyse whether and to what extent archaeological knowledge can influence visuospatial attention whilst interacting with stone tools. Archaeologists were found to pay more visual attention to the middle region and the knapped surface. Differences between the visual exploration of choppers and handaxes were also found. Although the general pattern of distribution of the visual attention was similar to naïve subjects, participants with archaeological experience paid more attention to functionally relevant regions. Individuals with archaeological experience directed more attention to the upper region and the knapped surface of the tools, whilst naïve participants spent more time viewing the middle region. We conclude that although both groups could direct their attention to action relevant features in stone tools, functional affordances had a greater effect in subjects with previous experience. Affordances related to manipulation triggered lower attention and showed no differences between participants.Junta de Castilla y León and co-financed by the European Social Funds (EDU/574/2018), by MCIN/AEI/ of the Spanish Government co-financed by ERDF Funds (Atapuerca Project: PGC2018-093925-B-C31/32) and by the Italian Institute of Anthropology (ISITA)
