Scientific Production in Children's Literatura Through the Web of Science
Children's literature has raised the interest of different disciplines and has strongly emerged not only in society but also in school and university curricula. This paper aims to analyse production in children's literature and determine the discipline's scientific activity published in international scientific journals indexed in the Web of Science. A total of 1,558 papers published in 474 journals were retrieved. The results show an increase in the number of papers on children's literature over time. Document typology was highly diverse, scientific articles and book reviews accounting for more than 85% of the total production. Lion and the Unicorn, Children's Literature in Education, and International Research in Children's Literature were the journals with the highest production. The journals analysed were classified under 96 different subject categories, Literature and Educational research being the areas with the largest number of publications
Blitzkrieg against democracy: gender equality and the rise of the populist radical right in Spain
Populist radical right parties (PRRPs) are generally considered detrimental to
democracy. Research on their damaging potential tends to focus on their influence in triggering policy backsliding but leaves the promotion of gender equality
out of the equation. This study explores the case of Vox in Andalusia, a southern
region of Spain, to show how PRRPs also contribute to de-democratization
through their capacity to erode the equality framework. We demonstrate how
they can effectively dismantle and reframe crucial policies, even when not in
office. This opens new analytical pathways for studying the role of PRRPs in
undermining democratic systems.Alba Alonso wishes to acknowledge the funding received from the Xunta de Galicia to support her research group Rede Armela USC (grant number ED431B 2020/23).S

ADM Pseudotensors, Conserved Quantities and Covariant Conservation Laws in General Relativity
The ADM formalism is reviewed and techniques for decomposing generic
components of metric, connection and curvature are obtained. These techniques
will turn out to be enough to decompose not only Einstein equations but also
covariant conservation laws. Then a number of independent sets of hypotheses
that are sufficient (though non-necessary) to obtain standard ADM quantities
(and Hamiltonian) from covariant conservation laws are considered. This
determines explicitely the range in which standard techniques are equivalent to
covariant conserved quantities. The Schwarzschild metric in different
coordinates is then considered, showing how the standard ADM quantities fail
dramatically in non-Cartesian coordinates or even worse when asymptotically
flatness is not manifest; while, in view of their covariance, covariant
conservation laws give the correct result in all cases.Comment: 40 page
Reseña de muestra artística: La imagen y la palabra: un recorrido por la muestra <i>Itinerarios</i> de Juan Carlos Romero
Recorrer la muestra de Juan Carlos Romero, es una bella forma de conocer un artista que trascendió las pautas estéticas y las tendencias que hicieron mella a partir de la década del cincuenta en Argentina; es a la vez conocer un fragmento de nuestra historia inscripta en una gran diversidad de formatos, técnicas y soportes; es, por otro lado, dejarse llevar por la fuerza de la palabra que desde el conceptualismo hasta los afiches callejeros no deja de interpelarnos.Facultad de Humanidades y Ciencias de la Educació

Ultraviolet spectra of extreme nearby star-forming regions --- approaching a local reference sample for JWST
Nearby dwarf galaxies provide a unique laboratory in which to test stellar
population models below . Such tests are particularly important for
interpreting the surprising high-ionization UV line emission detected at
in recent years. We present HST/COS ultraviolet spectra of ten nearby
metal-poor star-forming galaxies selected to show He II emission in SDSS
optical spectra. The targets span nearly a dex in gas-phase oxygen abundance
() and present uniformly large specific star
formation rates (sSFR ). The UV spectra confirm
that metal-poor stellar populations can power extreme nebular emission in
high-ionization UV lines, reaching C III] equivalent widths comparable to those
seen in systems at . Our data reveal a marked transition in UV
spectral properties with decreasing metallicity, with systems below
() presenting minimal
stellar wind features and prominent nebular emission in He II and C IV. This is
consistent with nearly an order of magnitude increase in ionizing photon
production beyond the -ionizing edge relative to H-ionizing flux
as metallicity decreases below a fifth solar, well in excess of standard
stellar population synthesis predictions. Our results suggest that often
neglected sources of energetic radiation such as stripped binary products and
very massive O-stars produce a sharper change in the ionizing spectrum with
decreasing metallicity than expected. Consequently, nebular emission in C IV
and He II powered by these stars may provide useful metallicity constraints in
the reionization era.Comment: 27 pages, 13 figures, 11 tables, accepted for publication in MNRA
Insights into the potential carcinogenicity of micro- and nano-plastics
There is a growing concern regarding the potential health effects that continuous exposure to environmental micro- and nano-plastics (MNPLs) may cause on humans. Due to their persistent nature, MNPLs may accumulate in different organs and tissues and may induce in the long term the development of cancer. The present study aimed to review the existing literature on the carcinogenic potential of MNPLs. As studies directly assessing carcinogenicity were expected to be scarce, studies dealing with indirect outcomes associated with the carcinogenic process were considered in the literature search. Of the 126 studies screened, 19 satisfied the inclusion criteria. Besides, 7 additional cross-referenced articles, identified through a careful reading of the previously selected papers, also met the inclusion criteria and, consequently, were included in the review. Most of the selected studies were performed using in vitro models whereas about 40% of the studies were done in rodents, although none of them included a 2-year carcinogenicity assay. Most of the reviewed studies pointed out the potential of MNPLs to induce inflammation and genotoxicity, the latter being recognized as a strong predictor of carcinogenicity. These, along with other important findings such as the MNPLs’ ability to accumulate into cells and tissues, or their capacity to induce fibrosis, may suggest an association between MNPLs exposures and the carcinogenic potential. Nevertheless, the limited number of available studies precludes reaching clear conclusions. Therefore, this review also provides several recommendations to cover the current knowledge gaps and address the future evaluation of the MNPLs’ carcinogenic risk
A LÍRICA MODERNISTA DE ERNANI FORNARI:PRESENÇA SÓCIO-HISTÓRICA EM TREM DA SERRA
In search for restoring Rio Grande do Sul’s Modernist Movement, this article presents a study on Ernani Fornari’s poem "O Trem da Serra", focusing on its historical and social aspects. Ernani Fornari was an influent personality in the Modernism in Rio Grande do Sul. Through "Trem da Serra" - a colonial poem from the Italian region – he expressed some of the most decisive aspects of Modernist doctrine, incorporating local language, dialoguing with other arts, accepting the speed of changes and presenting a unique view over the landscape and history that are part of Rio Grande do Sul’s mountain range. Na tentativa de recuperar os estudos de modernismo no Rio Grande do Sul. Apresenta-se aqui um estudo sobre O Trem da Serra de Ernani Fornari, focalizado nos aspectos Sócio-Históricos da Obra. Ernani Fornari foi um grande expoente do Movimento Modernista gaúcho e conseguiu com o Trem da Serra – O poema Colonial da região italiana- reunir as mais decisivas variáveis da doutrina modernista — incorporar a linguagem da vida diária, dialogar com as outras artes, aceitar a velocidade das transformações — com uma atenção rara, rarísssima para a paisagem, a história e a sensibilidade próprias de uma parte importante do Rio Grande do Sul, a Serra
