Language acculturation among the children of immigrants in Spain at the end of the prodigious decade of immigration
(Editorial Universidad de Alcalá, 2023)In Spain, few studies have analyzed how children of immigrants combine the acquisition of Spanish with the maintenance/acquisi- tion of heritage languages. This paper moves into that direction by exploiting data from a ... -
Layer-averaged approximation of Navier–Stokes system with complex rheologies
(EDP Sciences, 2023)In this work, we present a family of layer-averaged models for the Navier–Stokes equations. For its derivation, we consider a layerwise linear vertical profile for the horizontal velocity component. As a particular case, ... -

Lifelong Learning: Use of Psychological Factors in the Greek Public Administration
(UIKTEN, 2023)The integration of occupational psychology principles into human resource management is considered appropriate to increase employee productivity and the effectiveness of public sector organizations. In Greece, the use of ... -
Local and global well-posedness for the critical Schrödinger-Debye system
(American Mathematical Society - AMS, 2013)We establish local well-posedness results for the Initial Value Problem associated to the Schrödinger-Debye system in dimensions N = 2,3 for data in H^s x H^l, with s and l satisfying max{0, s − 1} ≤ l ≤ min{2s, s + 1}. In ... -

(2012)Presentamos un avance de los resultados de una investigación sobre el sentido númerico en alumnos y alumnas de primero y segundo de Educación Primaria de la provincia de Córdoba. Se utilizó un test estandarizado y ... -
Mathematical practical sessions with manipulatives: Trainee teachers’ perceptions of their utility
(Education Association of South Africa, 2019)This study presents the perceptions of trainee teachers regarding the realisation of practical mathematical sessions to expand on the concepts that are taught in primary education using manipulatives. For a 4-month period, ... -
Mathematics in the Spanish press: a case study of the 18th century journal Semanario de Salamanca
(Springer, 2023)Old mathematics books and textbooks have always been sources of relevant information for researchers working on the history of mathematics and mathematics education. However, helpful information about this field can also ... -

(Universidad de Buenos Aires, 2024)Del total de instituciones de gestión estatal y privada que dictan la carrera de agronomía el 56% se encuentran en la Región Pampeana y el 44% en el resto de las otras regiones geográficas de la Argentina. Existen múltiples ... -
MC64-ClustalWP2: A Highly-Parallel Hybrid Strategy to Align Multiple Sequences in Many-Core Architectures
(PLOS, 2014)We have developed the MC64-ClustalWP2 as a new implementation of the Clustal W algorithm, integrating a novel parallelization strategy and significantly increasing the performance when aligning long sequences in architectures ... -
MC64-Cluster: Many-Core CPU Cluster Architecture and Performance Analysis in B-Tree Searches
(2017)The MC64-Cluster computer platform was designed, based on many-core CPU microprocessors: Tile64. MC64-Cluster architecture was outlined in terms of both hardware and software, including commands available to manage jobs ... -
MC64: A web platform to test bioinformatics algorithms in a many-core architecture
(Springer Berlin / Heidelberg, 2011)New analytical methodologies, like the so-called "next-generation sequencing" (NGS), allow the sequencing of full genomes with high speed and reduced price. Yet, such technologies generate huge amounts of data that demand ... -
Mean convex properly embedded [phi,e3]-minimal surfaces in R3
(2022)We establish curvature estimates and a convexity result for mean convex properly embedded [φ,e 3]-minimal surfaces in R3, i.e., φ-minimal surfaces when φ depends only on the third coordinate of R3. Led by the works on ... -
Measuring attitude towards mathematics using Likert scale surveys: The weighted average
(Public Library Of Science (PLOS), 2020)In the research on mathematics education, numerous Likert-type instruments estimating attitudes toward mathematics are sometimes composed of factors with a high correlation, which can make it difficult to assign the ... -
Medición de las actitudes hacia las matemáticas en maestros de Educación infantil en formación
