Magnetic materials based on layered double hydroxides: chemical design, processing and electrochemical applications
2018
Tras el descubrimiento del grafeno en 2004, los materiales bidimensionales han generado un interés creciente por parte de la comunidad científica que se prolonga hasta nuestros días. Junto a este material constituido por delgadas láminas de carbono, también existen materiales bidimensionales de naturaleza inorgánica entre los que predominan aquellos basados en fuerzas de van der Waals. Dicalcogenuros metálicos, fósforo negro o antimoneno son algunos de estos ejemplos. Sin embargo, también existen materiales 2D formados por láminas iónicas, donde son las fuerzas electrostáticas las que ejercen un papel fundamental en cuanto a la organización y estructura de dichos sistemas. Este es el caso d…
Identifying gene-environment interactions in schizophrenia: contemporary challenges for integrated, large-scale investigations
2014
European Community Recent years have seen considerable progress in epidemiological and molecular genetic research into environmental and genetic factors in schizophrenia, but methodological uncertainties remain with regard to validating environmental exposures, and the population risk conferred by individual molecular genetic variants is small. There are now also a limited number of studies that have investigated molecular genetic candidate gene-environment interactions (G x E), however, so far, thorough replication of findings is rare and G x E research still faces several conceptual and methodological challenges. in this article, we aim to review these recent developments and illustrate h…
Barnet som aktør og kunnskapsbærer – en utfordring for barnevernets profesjonelle ekspertise
2010
Author's version of an article published in the journal: Norges Barnevern. Also available from the publisher at: http://www.idunn.no/ts/tnb/2010/03/art04 During recent years, it has become more and more common to consider children as competent participants in their own lives, also in the child protective services. This agrees with the UN Convention on the Rights of the Child and more recent research on children and childhood. That is to say that the child is seen as the expert on his own life, at the same time as the child protective services with their professional expertise have competence to say what is best for children. What does this imply and how can we understand the relation betwee…
Revista iberoamericana de educación
2016
Poniendo de relieve el foco de estudio que ha orientado nuestra investigación, mostramos en este artículo algunas propuestas formativas que desarrollamos en las materias del Grado de Maestra/o en Educación Infantil que tenemos a nuestro cargo. Nuestra premisa es que el oficio docente no se sustenta, únicamente, en los saberes disciplinares transmitidos durante el período formativo. Los estudios con docentes de infantil y primaria que hemos hecho nos muestran que hay aspectos del hacer, del saber y del ser docente que escapan a esa formalización del conocimiento disciplinar; lo que nos ha hecho interrogar nuestras propias prácticas formativas. Por ello, hemos ido buscando en los saberes expe…
The origins of the aesthetic enjoyment of music - A review of the literature
2009
Listeners attribute a positive or negative value to music. This aesthetic experience is known to be observable over the individuals’ entire life span, from early childhood to old age, and in every culture. It is then often concluded that such an aesthetic experience constitutes part of the human nature, having an important biological foundation. This assumption leads to the question of how aesthetic experience of music originated in the biological evolution. In this paper, we will explore this question in the light of evolutionary psychology, cognitive science, and systems neuroscience. After reviewing the existing proposals, we conclude that the explanation of the origin of aesthetic expe…

Creativity in Middle Childhood: Influence of Perceived Maternal Sensitivity, Self-esteem, and Shyness
2016
This study aimed to examine the relationship between maternal sensitivity and affect, as perceived by the child, and childhood creativity. Self-esteem and shyness were considered mediating factors. A total of 151 elementary school pupils were tested on verbal and pictorial creativity, self-esteem, and perceived maternal affect and sensitivity. Their teachers assessed each child’s shyness in their relations at school. A Multiple Indicators and Multiple Causes (MIMIC) model of the causal relationships among the study’s variables was tested. Results supported this theoretical model of causality. Maternal sensitivity had a significant, direct, positive effect on self-esteem, and a direct negati…
Teachers’ Knowledge Regarding Autism Spectrum Disorder (ASD): A Systematic Review
2021
The increasing number of students with autism spectrum disorder (ASD) in mainstream education environments require teachers to know how to identify their needs, being capable to adapt their education processes and make their inclusion easier. The purpose of this study is to conduct a systematic review about teachers’ knowledge of ASD, including teachers from any stage and specialization. The research has been conducted from four databases (Web of Science, Scopus, PsycInfo and Google Scholar) during the period of 2015–2020. In total, 25 articles were analyzed. The results show that, in general, teachers’ knowledge of ASD is poor. It depends on the education stage (being higher in early child…
The frequency of parents’ reading-related activities at home and children's reading skills during kindergarten and Grade 1
2012
Abstract This longitudinal study investigated the associations between the frequency of parents’ reading-related activities at home and their children's reading-related skills during the transition from kindergarten to Grade 1. Longitudinal data were obtained for 1436 Finnish children (5- to 6-year-olds at baseline) and their mothers and fathers. 684 girls and 752 boys participating in the study represented four Finnish municipalities. The reading skills of the children were measured four times: at the beginning and at the end of their kindergarten year, and at the beginning and at the end of Grade 1. In kindergarten, decoding tests were administered individually. In Grade 1, group tests in…
Pedagogy-related tensions in flexibly scheduled early childhood education and care
2020
In flexibly scheduled early childhood education and care (ECEC), the timing of care depends on parents’ non-standard working hours. Multiple individual schedules and care times in a child group may cause irregularity in a child’s daily structures, and a child may miss a standard hour’s activities that are led by teachers with a pedagogical education. In this context, the significance and definition of pedagogy is vague and tensional. This study aimed at disclosing discursive tensions related to pedagogy in flexibly scheduled ECEC constructed in interviews by Finnish teachers and childcare nurses (n = 31). The analysis of the interview data followed the principles of discursive psychology. C…
