Francia : ¿instrumentalización de la COVID-19 contra la igualdad escolar?
2021
La pandemia de COVID-19 ha puesto a prueba los sistemas educativos. Este artículo trata del caso francés, en el que tuvo lugar un confinamiento de dos meses, seguido de una reanudación muy parcial y selectiva del curso antes del verano, que no llegó a funcionar de nuevo realmente hasta septiembre, en condiciones sin precedentes. Muestra que lejos de ser un paréntesis excepcional, la crisis sanitaria fue utilizada por el gobierno para tratar de imponer cambios estructurales. Estas conclusiones se derivan de un análisis de las lógicas que estaban previamente en marcha en los proyectos de reforma de la enseñanza francesa, lo que permite distinguir entre las respuestas puntuales a una situación…
DAZAP2 acts as specifier of the p53 response to DNA damage.
2021
Abstract The DNA damage-responsive tumor suppressors p53 and HIPK2 are well established regulators of cell fate decision-making and regulate the cellular sensitivity to DNA-damaging drugs. Here, we identify Deleted in Azoospermia-associated protein 2 (DAZAP2), a small adaptor protein, as a novel regulator of HIPK2 and specifier of the DNA damage-induced p53 response. Knock-down or genetic deletion of DAZAP2 strongly potentiates cancer cell chemosensitivity both in cells and in vivo using a mouse tumour xenograft model. In unstressed cells, DAZAP2 stimulates HIPK2 polyubiquitination and degradation through interplay with the ubiquitin ligase SIAH1. Upon DNA damage, HIPK2 site-specifically ph…
SOMATISKIE FRAZEOLOĢISMI K. ULMAŅA LATVIEŠU-VĀCU VĀRDNĪCĀ (1872) UN K. ULMAŅA / G. BRAŽES VĀCU-LATVIEŠU VĀRDNĪCĀ (1880)

The paper analyses Latvian and German somatic idioms in the dictionaries by K. Ulmann and K. Ulmann / G. Braže. Up to now the researchers of Latvian phraseology have not focused to analyse these theme – especially in diachronic aspect. The paper presents the most fixed somatic idioms in the Latvian and German and their equivalence types. The author compares with the meanings of idioms from the first dictionary (1638) to modern electronic dictionary “Modern Latvian dictionary”. KEY WORDS: the dictionaries by K. Ulmann and K. Ulmann / G. Braže, somatic idioms, somatic components, the equivalence types of German–Latvian somatic idioms. DOI: http://dx.doi.org/10.15181/rh.v19i0.1329

Maxillofacial hard tissues have several differences compared to bones of other localizations of the human body. These could be due to the different embryological development of the jaw bones compared to the extracranial skeleton. In particular, the immigration of neuroectodermally differentiated cells of the cranial neural crest (CNC) plays an important role. These cells differ from the mesenchymal structures of the extracranial skeleton. In the ontogenesis of the jaw bones, the development via the intermediate stage of the pharyngeal arches is another special developmental feature. The aim of this review was to illustrate how the development of maxillofacial hard tissues occurs via the cra…
Sex-specific responses to cold in a very cold-tolerant, northern Drosophila species
2021
Funding: This work was supported by Academy of Finland projects 268214 and 322980 to MK and a NERC (UK) grant NE/P000592/1 to MGR. Organisms can plastically alter resource allocation in response to changing environmental factors. For example, in harsh conditions, organisms are expected to shift investment from reproduction toward survival; however, the factors and mechanisms that govern the magnitude of such shifts are relatively poorly studied. Here we compared the impact of cold on males and females of the highly cold-tolerant species Drosophila montana at the phenotypic and transcriptomic levels. Although both sexes showed similar changes in cold tolerance and gene expression in response…
Demonstration of background rejection using deep convolutional neural networks in the NEXT experiment
2021
[EN] Convolutional neural networks (CNNs) are widely used state-of-the-art computer vision tools that are becoming increasingly popular in high-energy physics. In this paper, we attempt to understand the potential of CNNs for event classification in the NEXT experiment, which will search for neutrinoless double-beta decay in Xe-136. To do so, we demonstrate the usage of CNNs for the identification of electron-positron pair production events, which exhibit a topology similar to that of a neutrinoless double-beta decay event. These events were produced in the NEXT-White high-pressure xenon TPC using 2.6 MeV gamma rays from a Th-228 calibration source. We train a network on Monte Carlo-simulat…
The path of liberation. Women’s associationism and workers’ cultures in the Second Republic (1931-1936)
2021
El presente texto reflexiona sobre algunas experiencias asociativas de las mujeres de distintas organizaciones femeninas de izquierda durante la Segunda República española (1931-1936). A través de ellas, las mujeres aumentaron su presencia pública en este período, sus vinculaciones y su compromiso, a través de múltiples acciones y propuestas. Pero a la vez, estas experiencias incrementaron el contacto y la interacción entre ellas, posibilitando su reconocimiento mutuo, su «apoyo mutuo», y con él, el desarrollo de su conciencia y de su identidad como mujeres, como socialistas y como trabajadoras. En otras palabras, su identidad como «compañeras», y su sociabilidad asociativa como «camino de …

Individual alpha peak frequency, an important biomarker for live Z-Score training neurofeedback in adolescents with learning disabilities
2021
Learning disabilities (LDs) have an estimated prevalence between 5% and 9% in the pediatric population and are associated with difficulties in reading, arithmetic, and writing. Previous electroencephalography (EEG) research has reported a lag in alpha-band development in specific LD phenotypes, which seems to offer a possible explanation for differences in EEG maturation. In this study, 40 adolescents aged 10–15 years with LDs underwent 10 sessions of Live Z-Score Training Neurofeedback (LZT-NF) Training to improve their cognition and behavior. Based on the individual alpha peak frequency (i-APF) values from the spectrogram, a group with normal i-APF (ni-APF) and a group with low i-APF (li-…
Le poète comme cortège de voix : écrire et réciter la poésie dans l'oeuvre de Jacques Roubaud
2021
International audience; Anthologiste, traducteur, revuiste, Jacques Roubaud compte parmi ces poètes contemporains qui n'ont cessé de donner à entendre d'autres voix que la leur. Son oeuvre renoue avec la définition étymologique de la polyphonie comme pluralité de voix à cela près que le poète roubaldien se définit comme une mémoire de poésie qui cite et récite sans doute plus qu'elle ne chante. De la poésie médiévale japonaise aux chants indiens d'Amérique du Nord en passant par la poésie des troubadours, le sonnet de Marot à Malherbe et la poésie française de 1914 à 1932, Roubaud rejoue l'expérience enfantine de la récitation. Il fait ainsi de sa propre voix poétique un cortège voix famili…
Are future L3-German teachers prepared to increase students' metacognition and crosslinguistic awareness in the multilingual classroom? An analysis o…
2021
The multilingual turn in Europe requires an adaption of foreign language teaching approaches. This study provides theoretical and empirical reasons to treat crosslinguistic awareness as a potentially beneficial metacognitive tool for multilingual language learners. Furthermore, it explores whether future foreign language teachers are introduced to crosslinguistic awareness as a teaching tool in university teacher education. A sample of 27 national and local documents concerning parts of German foreign language teacher education in Denmark and Norway were analyzed for concepts such as multilingualism, metacognition, and crosslinguistic awareness. The document analysis showed that the three m…
El enfoque franciscano y la ciencia. De la Escolástica Tardía a la vía moderna
2021
Resumen La Escolástica Tardía marca un hito en la historia del pensamiento filosófico. En este periodo se establecen las bases de un profundo proceso de transformación en la forma de observar la naturaleza a través de una minuciosa recolección de datos, experimentos y posteriores análisis. El enfoque franciscano da prioridad a aquel sentido práctico del filosofar que se funda sobre la existencia real y desembarca en la acción. Los pensadores franciscanos analizan las realidades del mundo con un dinamismo pragmático sumamente original. Abstract Late Scholasticism marks a milestone in the history of philosophical thought. In this period, a profound process of transformation took place in the …

Age-related macular degeneration (AMD) is a common irreversible ocular disease characterized by vision impairment among older people. Many risk factors are related to AMD and interact with each other in its pathogenesis. Notably, oxidative stress and choroidal vascular dysfunction were suggested to be critically involved in AMD pathogenesis. In this review, we give an overview on the factors contributing to the pathophysiology of this multifactorial disease and discuss the role of reactive oxygen species and vascular function in more detail. Moreover, we give an overview on therapeutic strategies for patients suffering from AMD.

A contribution to the characterization of Ruppia drepanensis (Ruppiaceae), a key species of threatened Mediterranean wetlands
2021
To elucidate the taxonomic status of Ruppia drepanensis Tineo ex Guss. (Alismatales, Ruppiaceae), we performed morphological analysis and DNA barcoding of historical materials (including the lectotype) and fresh samples (including those from a recently discovered population near the locus classicus in Sicily, Italy). We conclude that R. drepanensis is a separate species, closely related to R. spiralis L. ex Dumort., that occurs in temporary inland waters from the western to central sectors of the Mediterranean region. We also highlight the importance of vouchers and the need to link molecular investigations to field, ecological, and morphological investigations.
Hormonal responsiveness in the Trier Social Stress Test and the dexamethasone‐corticotropin releasing hormone test in healthy individuals
2021
A number of different laboratory procedures investigate the hormonal response in a standardized pharmacological challenge test (dexamethasone-corticotropin releasing hormone; DEX-CRH) or in a psychosocial stress induction on the hypothalamic-pituitary-adrenocortical axis by the Trier Social Stress Test (TSST). However, the magnitude of the response related to the different stressors and the interaction of the responsiveness between the two tests is still unclear. Fifty-two participants underwent both the DEX-CRH test and the TSST on two separate days. The cortisol and the plasma adrenocorticotropic hormone (ACTH) release were assessed before and after the stress tests. For a specification o…
Metallic subnanometer porous silicon: A theoretical prediction
2021
In the present work, T-Si, a silicon-based counterpart of T-carbon, has been designed with the aid of density functional theory (DFT) calculations. Its stability has been fully confirmed from energetic, mechanical, lattice dynamic, and thermodynamic aspects. Due to the space extrusion, the delocalized electrons on the ${\mathrm{Si}}_{4}$ tetrahedrons are squeezed onto the inter-tetrahedron $\mathrm{Si}\ensuremath{-}\mathrm{Si}$ bonds, which therefore leads T-Si to be metallic. Furthermore, the electronic conductivity of this new material has also been predicted and discussed in this work. This new silicon allotrope with a low density of $0.869\mathrm{g}/{\mathrm{cm}}^{3}$ can even floats on…
NOVCOJUSĪ LEKSIKA J. LANGIJA VĀRDNĪCĀ (1685): NAUDAS VIENĪBU NOSAUKUMI
2021
The Latvian language dictionary of J. Langius (1685) does not contain a large number of terms denoting monetary units – altogether there are 11 of them (ārtaugs, dālderis, diķis, eiduks, grosis, kauss, mārka, skatiks, sķiliņģis, vērdiņģis, zelta gabals), as well as some other money-related lexemes (e.g., sīknauda, vara nauda etc.) which are not designations of monetary units and therefore are not analyzed in this article. These lexemes are included in most 17–19th century dictionaries, and sometimes are borrowed from one dictionary into another. For instance, J. Langius has taken over the words included in the dictionary of G. Mancelius, but later J. Lange, in his turn, refers to J. Langius…
Educación formal e informal en confinamiento : una creciente desigualdad de oportunidades de aprendizaje
2021
El cierre de escuelas en Cataluña para contener los efectos de la COVID-19 obligó a las escuelas y las familias a reaccionar en poco tiempo y sin planificación previa ante un nuevo escenario de enseñanza. Este artículo evalúa el impacto del cierre escolar sobre la desigualdad de aprendizaje entre niños de diferentes contextos sociales en Cataluña. A partir de los datos de una encuesta en línea realizada entre el 26 y el 30 de marzo (n = 35.419) a familias con hijos entre 3 y 18 años, nuestro análisis muestra que las oportunidades de aprendizaje varían significativamente en función de las características del alumnado. Durante el confinamiento, algunas escuelas consiguieron adaptarse a las nu…

Controlling Spin-Correlated Radical Pairs with Donor-Acceptor Dyads: A New Concept to Generate Reduced Metal Complexes for More Efficient Photocataly…
2021
Abstract One‐electron reduced metal complexes derived from photoactive ruthenium or iridium complexes are important intermediates for substrate activation steps in photoredox catalysis and for the photocatalytic generation of solar fuels. However, owing to the heavy atom effect, direct photochemical pathways to these key intermediates suffer from intrinsic efficiency problems resulting from rapid geminate recombination of radical pairs within the so‐called solvent cage. In this study, we prepared and investigated molecular dyads capable of producing reduced metal complexes via an indirect pathway relying on a sequence of energy and electron transfer processes between a Ru complex and a cova…
Academic competence, teacher–student relationship, and violence and victimisation in adolescents: The classroom climate as a mediator
2021
School violence is a serious social and public health problem prevalent worldwide. Although the relevance of teacher and classroom factors is well established in the literature, few studies have focused on the role of teacher perceptions in school violence and victimisation and the potential mediational role of classroom climate in this relationship. A total of 2399 adolescents (50% girls), aged between 11 and 18 years (M = 14.65, SD = 1.78) and enrolled in five Spanish Secondary Compulsory Education schools completed measures of classroom climate, school violence towards peers and perception of peer victimisation, and their teachers informed about their academic competence and the teacher&…
Plant essential oils in controlling fungal colonization on wooden substrate
2021
In order to control fungal colonization and the related deterioration process of cultural objects, several chemical compounds are actually utilised. These products generally are toxic, not biodegradable and persisting for long time in the environment, also acting on not-targeted biological systems. In this study, specifically to wooden cultural object, Origanum vulgare L. and Thymus vulgaris L. essential oils are proposed as green biocides to contrast the development of Penicillium chrysogenum, Aspergillus flavus and Aspergillus niger fungal species. The aim is replacing toxic products with natural molecules, proposing alternative methodologies supporting the using of non-toxic novel compou…

Children’s Fruit and Vegetable Preferences Are Associated with Their Mothers’ and Fathers’ Preferences
2021
Children’s preference for fruit and vegetables must emerge during childhood. At children’s homes, mothers and fathers influence children’s developing food preferences with their own preferences and actions. The purpose of the study was to reveal the association parents have with their children’s fruit and vegetable preferences. The study was conducted in a sample of Finnish mothers and fathers of 3–5-year-old children. The participants were recruited, and questionnaires distributed through early childhood education and care centers in 2014 and 2015. The results showed considerable variance in the children’s preferences, and were more similar with their father’s, than their mother’s preferen…

Soil is the best testifier of the diachronous dawn of the Anthropocene
2021
Humans act at worldwide scale as a growing geomorphic agent since mid‐Holocene (8,200–4,200 y BP) through the pervasive impacts of domestication, deforestation, agriculture, urbanization, and mining. The concept of Anthropocene has been introduced exactly to indicate the timespan in which humans have joined with other natural forces in impacting the outermost shell of the planet and the biosphere. Soils, which are the Earth's skin, are sensitive archives of any major human‐induced local to global change. Especially when buried, soils can permanently preserve the primordial traces of a significant impact of man on the environment, which occurred at different times and rates in different area…

Modeling Rain Isotopic Composition under Orographic Control: A Landscape Approach for Hydrogeological Applications
2021
Oxygen isotopic composition is useful for individuating recharge areas of groundwater bodies by the comparison with those of local rainfalls. While on a global scale general relationships, such as the isotopic vertical gradient or continentality effects, efficiently describe spatial variations of the isotopic signature, hydrogeological applications need spatial models that are more focused on the effects of local topographic structures and/or subsoil geology. This work presents a case study in northeastern Sicily (Italy) characterized by complex geological and orographic structures, in which isotopic composition of rainfalls is governed by orographic effects and the varying initial composit…
L'interpretazione conforme e i limiti alla discrezionalità del giudice nell'interpretazione della legge

: The essay traces the evolution of constitutional jurisprudence about consistent interpretation of Constitution up to its most recent arrivals, which are still insecure today and burdened with not removed theoretical-reconstructive aporias. An attempt is made to explain the perspective change on the basis that the consistent interpretation of the origins was aimed at innervating the new Constitution in the legal system and at entrenching the constitutional culture in the courts. Subsequently, theoretical, political and factual justifications, combined with both judicial substitution and crisis of politics, have made the judiciary emerge as a “third giant” alongside the legislative and exec…
Impeller optimization in crossflow hydraulic turbines
2021
Crossflow turbines represent a valuable choice for energy recovery in aqueducts, due to their constructive simplicity and good efficiency under variable head jump conditions. Several experimental and numerical studies concerning the optimal design of crossflow hydraulic turbines have already been proposed, but all of them assume that structural safety is fully compatible with the sought after geometry. We show first, with reference to a specific study case, that the geometry of the most efficient impeller would lead shortly, using blades with a traditional circular profile made with standard material, to their mechanical failure. A methodology for fully coupled fluid dynamic and mechanical …

Wage Gap as a Possible Determinant of Gender Inequality
2021
Recent academic researchers have indicated that there are possible inequalities concerning work and pay in different countries, professions and economic sectors. The aim of current research is to analyse recent scientific findings on the wage gap depending on gender and empirical data in Latvia using EU-SILC surveys, Labour Surveys and monthly statistical data on wages and salaries for women and men. The findings indicated that in various economic fields and occupations women were under-represented, and amongst most of these fields the modal net wage interval for women was lower than the modal net wage interval for men. It was also concluded that in January 2018 the average gross income fro…
