Linguistic diversity and assessment in multilingual schools
2018
En un entorno en el que la diversidad lingüística es natural, la metodología de evaluación afronta nuevos retos. La equidad en el proceso evaluativo aconseja la consideración de aspectos relacionados con las características psicométricas de las pruebas, el desarrollo de la competencia lingüística, o el contexto sociolingüístico, a través de modelos explicativos sobre las variables contextuales de naturaleza lingüística que inciden en el rendimiento. Utilizando datos poblacionales de centros educativos de segundo curso de enseñanza secundaria obligatoria que ofertan más de un modelo lingüístico en la Comunidad Autónoma del País Vasco (N=45), este trabajo analiza las respuestas de 2783 estudi…
Prompt and delayed spectroscopy of 203At : Observation of a shears band and a 29/2+ isomeric state
2018
Using fusion-evaporation reactions, a gas-filled recoil separator, recoil-gating technique and recoil-isomer decay tagging technique we have extended the level scheme of 203 At ( N = 118 ) significantly. We have observed an isomeric [ τ = 14.1 ( 3 ) μ s ] state with a spin and parity of 29 / 2 + . The isomeric state is suggested to originate from the π ( h 9 / 2 ) ⊗ ∣ ∣ 202 Po ; 11 − ⟩ coupling, and it is depopulated through 286 keV E 2 and 366 keV E 3 transitions. In addition, we have observed a cascade of magnetic-dipole transitions which is suggested to be generated by the shears mechanism. peerReviewed
Amantadine in the Treatment of Sexual Inactivity in Schizophrenia Patients Taking Atypical Antipsychotics—The Pilot Case Series Study
2021
Sexual dysfunctions in people with schizophrenia are more severe than in the general population and are an important element in the treatment of schizophrenia. The mechanism of sexual dysfunction in patients treated for schizophrenia may be related to the side effects of antipsychotic drugs (hyperprolactinemia, suppression of the reward system), but it may also be related to the pathogenesis of schizophrenia itself. The aim of the study was to present the possibility of using amantadine in the treatment of sexual dysfunction in schizophrenia without the concomitant hyperprolactinemia. In an open and naturalistic case series study, five men treated for schizophrenia in a stable mental state …
Del álgebra a la geometría : la sistematización de las coordenadas cartesianas y la representación gráfica de funciones en la Introductio in analysin…
2012
Este trabajo de investigación explora la presentación del sistema de coordenadas cartesianas en la Introductio in Analysin Infinitorum de Euler y en los libros de texto de Lacroix Traité du calcul différentiel et du calcul intégral and Traité Élémentaire de Trigonométrie Rectiligne et Sphérique, et d’Application de l’Algèbre a la Géométrie, indagando qué componentes hicieron posible su sistematización, y teniendo presente las dificultades de los estudiantes en el uso de las coordenadas cartesianas. Es un hecho harto conocido que los estudiantes tienen dificultades en la comprensión y el uso de la representación de funciones en el sistema de coordenadas cartesianas (SCC). Esta problemática d…
Symbiotic status alters fungal eco‐evolutionary offspring trajectories
2023
Despite host-fungal symbiotic interactions being ubiquitous in all ecosystems, understanding how symbiosis has shaped the ecology and evolution of fungal spores that are involved in dispersal and colonization of their hosts has been ignored in life-history studies. We assembled a spore morphology database covering over 26,000 species of free-living to symbiotic fungi of plants, insects and humans and found more than eight orders of variation in spore size. Evolutionary transitions in symbiotic status correlated with shifts in spore size, but the strength of this effect varied widely among phyla. Symbiotic status explained more variation than climatic variables in the current distribution of…
Palladium-Catalyzed Direct Arylation of Heteroaromatics with Activated Aryl Chlorides Using a Sterically Relieved Ferrocenyl-Diphosphane
2012
International audience; The palladium-catalyzed direct arylations at C3 or C4 positions of heteroaromatics are known to be more challenging than at C2 or C5 positions. Aryl chlorides are also challenging substrates for direct arylation of heteroaromatics. We observed that in the presence of a palladium-catalyst combining only 0.5 mol % of Pd(OAc)2 with the sterically relieved new ferrocenyl diphosphane Sylphos, the direct arylation at C3 or C4 of oxazoles, a benzofuran, an indole, and a pyrazole was found to proceed in moderate to high yields using a variety of electron deficient aryl chlorides. Turnover numbers up to 176 have been obtained with this catalyst. Assessment of the electron-don…
Computational Criteria for Hydrogen Evolution Activity on Ligand-Protected Au25-Based Nanoclusters
2023
The hydrogen evolution reaction (HER) is a critical reaction in addressing climate change; however, it requires catalysts to be generated on an industrial scale. Nanomaterials offer several advantages over conventional HER catalysts, including the possibility of atomic precision in tailoring the intrinsic activity. Ligand-protected metal clusters, such as the thiolate-protected MAu24(SR)18 (where M is Au, Cu, Pd), are of particular interest as not only are they electrocatalytically active toward HER, but the charge state and composition can be precisely tuned. Here, we present a comprehensive computational study examining how the charge state and dopants affect the catalytic activity of [MA…
Kształcenie świadomości językowej w gimnazjum – lekcje gramatyki
2015
W publikacji podjęto próbę odpowiedzi na pytanie, jak na poziomie gimnazjum realizowane są zapisy podstawy programowej z 2008 r. w zakresie świadomości językowej, w jaki sposób uczy się gramatyki języka polskiego i jakie wyniki uzyskują uczniowie. Materiał badawczy stanowiły dane zebrane w trakcie realizacji badania Dydaktyka literatury i języka polskiego w gimnazjum w świetle nowej podstawy programowej, obejmujące: wyniki zadań testowych sprawdzających wiedzę i umiejętności z zakresu świadomości językowej, wyniki obserwacji nieuczestniczących lekcji językowych, informacje uzyskane w wywiadach z nauczycielami i uczniami oraz w ankietach. Analiza danych pozwoliła stworzyć wieloaspektowy obra…
Extracellular Vesicles as Biological Shuttles for Targeted Therapies.
2019
The development of effective nanosystems for drug delivery represents a key challenge for the improvement of most current anticancer therapies. Recent progress in the understanding of structure and function of extracellular vesicles (EVs)—specialized membrane-bound nanocarriers for intercellular communication—suggests that they might also serve as optimal delivery systems of therapeutics. In addition to carrying proteins, lipids, DNA and different forms of RNAs, EVs can be engineered to deliver specific bioactive molecules to target cells. Exploitation of their molecular composition and physical properties, together with improvement in bio-techniques to modify their content are critical iss…
