Peri-Gondwanan Provenance and Geodynamic Evolution of The Guadaiza Nappe (Alpujarride Complex, Betic Cordilleras, Spain): Insights on The Paleotethyan Paleogeography

Based on the LA-ICP-MS U-Pb zircon ages of four metamorphic samples, we discuss the geochronology and provenance of the Guadaiza nappe, an allochthonous unit that underlies the Ronda peridotites (Betic Cordilleras, Spain). The Guadaiza nappe is composed of Triassic marbles overlying a metapelitic sequence with schists and migmatites. Zircons from a quartzite interlayered with the marbles yield a maximum depositional age of ca. 289 Ma that supports the Triassic age. The idiomorphic morphology of these Paleozoic zircon crystals and the lack of late-Variscan metamorphism (ca. 300 Ma) supports a proximal source area, and suggests that the marbles were discordantly deposited over the metapelitic sequence, along the northern margin of the Alboran microplate. The zircon patterns from the metapelitic sequence mainly yield Paleoproterozoic (ca. 1.6–2.5 Ga), Tonian–Stenian (ca. 1000 Ma), Ediacaran–Cryogenian (ca. 600 Ma) and Paleozoic (ca. 500 Ma) age clusters. These results suggest provenance from areas within the triangle bound by the West African Craton, the Metasaharan Craton and the Hun Superterrane during the Paleotethys opening (Silurian–Devonian). A Silurian–Carboniferous deposition age for the schist protoliths is constrained by the youngest detrital zircon population (ca. 443 Ma) and the Variscan age of their migmatization by an additional peak of around 299 Ma in the migmatites.This research was funded by Ministerio de Economía, Industria y Competitividad/Agencia Estatal de Investigación/Fondo Europeo de Desarrollo Regional, European Union, grant number CGL2017-82976-P and Grupos de Investigación, University of the Basque Country, grant number GIU20/017

Provenance Analysis of the Ojén Nappe and Its Implication for the Geodynamic History (Alpujárride Complex, Betic Cordilleras, Spain)

The Ojén nappe, an allochthonous unit that underlies the Ronda peridotites (Betic Cordilleras), is composed of Triassic marbles overlying a metapelitic sequence. In order to carry out an LA-ICP-MS U-Pb age determination and provenance analysis, detrital zircon grains from two quartzites interlayered within marbles and metapelites were extracted. The obtained results yield the youngest zircon population of 254 ± 3 Ma (Late Permian) with a mean Th/U ratio of 0.34 that supports both the Permian–Triassic age of the marble member and the felsic magma nature for zircon-bearing protoliths. The Permian zircons exhibit tight age peaks in three main populations of 292 ± 2 Ma, 278 ± 3 Ma, and 254 ± 3 Ma, in agreement with the main age populations reported from rhyolites and shallow crustal basaltic–andesite subalkaline rocks emplaced in transtensional Permian basins of the Variscan Orogen during the break-up of Pangea. Moreover, the analyzed detrital zircon grains yield age distributions with clear Tonian–Stenian (ca. 950–975 Ma), Ediacaran–Cryogenian (ca. 560–615 Ma), Ordovician (ca. 460–465 Ma), and Cisuralian peaks (ca. 280–290 Ma) and smoothed Mesoproterozoic peaks that point to a weak and residual Cadomian peri-Gondwanan terrane inheritance. The identified Middle Ordovician detrital zircon populations (460–465 Ma) strengthen the hypothesis that the Alborán domain would be located along the southern passive margin of the European Hunic superterrane.This research was funded by Ministerio de Economía, Industria y Competitividad/Agencia Estatal de Investigación/Fondo Europeo de Desarrollo Regional, European Union (grant number CGL2017-82976-P) and Grupos de Investigación, University of the Basque Country (grant number GIU20/017)

Comparison of social performance in children with profound deafness and children with normal hearing according to different informants

A partir de considerar la relevancia de un óptimo desarrollo social en edades tempranas sumado a las particularidades que adquiere el mismo en los niños con sordera, este trabajo se propuso comparar la competencia social de niños con sordera profunda y audición normal en función del género y la edad, examinando también el rol del nivel socioeconómico. Método. La muestra estuvo conformada por 32 niños con sordera profunda y 32 niños con audición normal, con edades comprendidas entre los 7 y 12 años que asistían a instituciones educativas y/o terapéuticas de la ciudad de Córdoba Capital (Argentina), también participaron los padres (n = 64) y docentes (n = 15). Los instrumentos utilizados fueron la escala MESSY en su versión para el docente y para el alumno y un cuestionario sociodemográfico aplicado a los tutores. Resultados. Al considerar la valoración realizada por los niños se observaron diferencias significativas de grupo, presentando el grupo con sordera mayores niveles de inadecuación social. Mientras que según la valoración de los docentes, los niños con y sin sordera, presentan niveles semejantes de inadecuación social. Con respecto al nivel socioeconómico, no se observaron diferencias estadísticamente significativas. Discusión. Se aprecian resultados diferenciales según el informante considerado. En términos generales, la sordera profunda no constituye un impedimento para el desarrollo de las habilidades sociales. Se discute la importancia de considerar otros factores contextuales y no sólo indicadores socioeconómicos.Introduction. Considering the relevance of an optimal social development at early ages and its particularities in deaf children, this study aimed to compare the children's social competence with profound deafness and normal hearing depending on sex and age, examining also the role of socioeconomic status. Method. Participants were 32 children with profound deafness and 32 children with normal hearing, from 7 to 12 years old, who were attending educational or therapeutic institutions of the city of Córdoba (Argentina), also participated parents (n = 64) and teachers (n = 15). The MESSY scale was used to assess social behavior in their versions for the teacher and for children, and also was applied a sociodemographic questionnaire to tutors. Results. Considering the auto-evaluation were not significant differences of group, the group of children with deafness showed higher levels of social inadequacy. While according to the evaluation of teachers, children with and without deafness have similar levels of social inadequacy. With regard to socioeconomic status, were not observed statistically significant differences. Discussion. The results were different according to the informant in question. In general, profound deafness is not an impediment to the development of social skills. We discuss the importance of considering other contextual factors, not just socioeconomic indicators.Fil: Ipiña, María Julia. Universidad Nacional de Córdoba.

Social competence in children with deep deafness

El objetivo de este estudio fue comparar el desempeño social de niños con sordera profunda asistentes a tres instituciones especializadas de la ciudad de Córdoba (Argentina) y evaluar el acuerdo entre distintos informantes (docentes - alumnos) acerca de la competencia social de los niños. La muestra no probabilística estuvo formada por 32 niños con edades comprendidas entre los 7 y 12 años, sus padres y docentes/profesionales (n = 15). Los niños asistían a instituciones con características particulares: A (oralista, n = 10), B (bilingüe, n = 9) y C (bilingüe, n = 13). Se utilizaron las versiones de autoinforme del alumno e informe del docente del MESSY. Los resultados obtenidos muestran que, a partir del autoinforme, los niños que concurren a la institución A presentan puntuaciones más altas en Sobreconfianza/Celos/Soberbia con respecto a los alumnos de las otras dos instituciones (B y C). Por otra parte, la relación entre el reporte de niños y docentes sólo se evidenció en la dimensión de Habilidades Sociales Apropiadas.This study aims to compare the social performance of children with deep deafness, who attend three specialized institutions of the city of Córdoba (Argentina) and to evaluate the information taken from different point of views (teachers - students) about the social competence of children. A non probabilistic sampling was used. Participants were 32 children aged between 7 and 12 years old, and their parents and professionals/ teachers (n = 15). Children attended institutions with particular characteristics: A (public oral, n = 10), B (public bilingual, n = 9) and C (private bilingual, n = 13). Data was obtained from the MESSY scale and students’ self reports. The findings determine that children who attend the A institution have higher scores on aspects such as overconfidence, jealousy and arrogance, compared to the other two institutions (B and C). On the other hand, the relation between children and teachers’ reports was only evident with regard to the appropriate social skills dimension.Fil: Molina, Leonardo. Universidad Nacional de Córdoba.

Superimposed training-based channel estimation for miso optical-OFDM vlc

In this paper, we investigate a novel channel estimation (CE)method for multiple-input and single-output (MISO) systems in visible lightcommunication (VLC). Direct current biased optical orthogonal frequencydivision multiplexing (DCO-OFDM) is commonly used in VLC where halfof the available subcarriers are spent to guarantee a real-valued outputafter the inverse fast Fourier transform operation. Besides, dedicated subcarriers are typically used for CE, thus, many resources are wasted andthe spectral efficiency is degraded. We propose a superimposed trainingapproach for CE in MISO DCO-OFDM VLC scenarios. Analytical expressions of mean squared error (MSE) and spectral efficiency are derived whenthe least squares estimator is considered. This analysis is valid for outdoorand indoor scenarios. For the CE error, simulation results of MSE showa perfect match with analytical expressions. Moreover, results prove thatthis technique guarantees a larger spectral efficiency than previous schemeswhere dedicated pilots were used. Finally, the optimal data power allocationfactor is also analytically derived.This work was supported in part by the National Secretary of Higher Education, Science, Technology, and Innovation (SENESCYT) in Ecuador and in part by the Spanish National Project TERESA-ADA (TEC2017-90093-C3-2-R) (MINECO/AEI/FEDER, UE).

The potential role of the adipokine HMGB1 in obesity and insulin resistance. Novel effects on adipose tissue biology

Discovery of the adipose tissue as a major source of signaling molecules almost three decades ago set a novel physiological paradigm that paved the way for the identification of metabolic organs as endocrine organs. Adipocytes, the main adipose tissue cell type, do not only represent the principal site of energy storage in form of triglycerides, but also produce a variety of molecules for short and long distance intercellular communication, named adipokines, which coordinate systemic responses. Although the best known adipokines identified and characterized hitherto are leptin and adiponectin, novel adipokines are continuously being described, what have significantly helped to elucidate the role of adipocyte biology in obesity and associated comorbidities. One of these novel adipokines is high-mobility group box 1 (HMGB1), a ubiquitous nuclear protein that has been recently reported to be dysregulated in obese dysfunctional adipocytes. Although the classical function of HMGB1 is related to inflammation and immunity, acting as an alarmin, novel advances evidence an active implication of HMGB1 in tissue remodeling and fibrosis. This review summarizes the current evidence on the mechanisms controlling HMGB1 release, as well as its role as a regulator of adipocyte function and extracellular matrix remodeling, with special emphasis on the potential of this novel adipokine as a target in the obesity treatment

Posets pluton: a geochronological piece in the puzzle of the Axial Zone of the Pyrenees

[EN]A detailed geochronological study was conducted on zircons from a diorite sample of the Posets pluton (Axial Zone, Pyrenees). The extracted igneous zircons constrain the emplacement of the pluton to 302 +/- 2 Ma and 301 +/- 3 Ma, by means of U-Pb sensitive high-resolution ion microprobe (SHRIMP) and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) analyses, respectively. Considering the syn- to late-tectonic emplacement of the Posets pluton during the main Variscan deformation event (D-2), the obtained ages constrain the long-lasting D-2, associated with the dextral transpression registered through the Axial Zone of the Pyrenees.This work was supported by grants EHUA13/03 and GIU20/017 from the University of the Basque Country (UPV/EHU) and CGL2017-82976 from the Ministerio de Economia, Industria y Competitividad / Agencia Estatal de Investigacion / Fondo Europeo de Desarrollo Regional, European Union.

La implicación del estudiantado en la resolución de conflictos sobre nuestro patrimonio cultural dentro y fuera del aula: investigar, conocer in situ, documentar y difundir.

El proyecto Patrimonio Herido plantea dos objetivos principales: fomentar el interés por la recuperación de bienes culturales en situación de peligro y reivindicar el rol del historiador del arte como profesional esencial en equipos transdisciplinares. Sus actividades formativas se desarrollan dentro y fuera del aula, destacando el conocimiento del patrimonio cultural de proximidad in situ, lo que genera vínculos significativos entre el estudiantado y los bienes que este selecciona para su estudio. Entre los resultados se solicita: realizar una ficha diagnóstico con los datos esenciales del bien; analizar los valores patrimoniales; describir su situación ante el peligro detectado; aportar soluciones coherentes transitivas, para detener los daños, y definitivas, para eliminarlos; aportar imágenes históricas, actuales y de futura propuesta. Cada año se exponen los resultados en el Encuentro Interuniversitario de Estudiantes (2024: III edición) donde, además, se desarrollan competencias y habilidades comunicativas y se participa en debates de manera crítica y razonada. Para el trabajo se plantean tres opciones: investigar un bien individual, bien siguiendo el modelo tradicional de ficha diagnóstico, o bien realizando un vídeo de TikTok donde se incluyan los resultados de la investigación; planificar un itinerario cultural a partir de elementos con daños comunes; o crear un juego tras la realización de un glosario de términos, conceptos o situaciones específicos aprendidos durante el curso. En todos los casos se integran las humanidades digitales y las TIC, demostrando que la disciplina de Historia del Arte cumple un papel fundamental para la sociedad, a quien se le da a conocer este trabajo mediante eventos de divulgación, tales como la Noche Europea de los Investigadores. Finalmente, cabe destacar que la recuperación y puesta en valor del patrimonio cotidiano genera beneficios en el ámbito local y su territorio, permitiendo la aplicación de diversos ODS.Universidad de Málaga.
