Promotion of school engagement through dialogic teaching practices in the context of a teacher professional development programme
2021
This study was conducted in the context of a teacher professional development programme that aimed to improve dialogic teaching in the classroom, and it describes the programme and examines the change in teachers' dialogic teaching practices and pupils' classroom engagement during the programme. Data on pupils' school engagement were collected using classroom video recordings and students' self-ratings at the end of the lesson including dialogic teaching practices. The participants comprised seven in-service teachers and their 140 pupils (10- to 15-year-olds) from two comprehensive schools. The findings indicated positive change in the use of dialogic teaching practices and in observed pupi…
Neutrinos from GRBs with ANTARES
2013
A search for muon neutrinos in coincidence with gamma-ray bursts with the ANTARES neutrino detector using data from the end of 2007 to 2011 is performed. Expected neutrino fluxes are calculated for each burst individually. The most recent numerical calculations of the spectra using the NeuCosmA code are employed, which include Monte Carlo simulations of the full underlying photohadronic interaction processes. The discovery probability for a selection of 296 gamma-ray bursts in the given period is optimised using an extended maximum-likelihood strategy. No significant excess over background is found in the data, and 90% confidence level upper limits are placed on the total expected flux acco…
Describir y dibujar en ciencias. La importancia del dibujo en las representaciones mentales del alumnado
2015
El presente trabajo pretende valorar los resultados obtenidos mediante la utilización del dibujo y de las descripciones a lo largo de una actividad basada en la observación de la morfología de las hormigas. Se plantea un trabajo individual y autónomo donde los participantes, en 3 etapas diferentes, deben tratar de dibujar o describir su observación de muestras vivas de hormigas. Los resultados de la investigación son muy significativos, puesto que encontramos diferencias estadísticas entre la utilización de las dos estrategias, así como entre las producciones de cada etapa, pudiendo ver cómo evolucionan sus representaciones mentales. Evidenciamos, de esta manera, que la estrategia de dibuja…
When the print meets the screen: Towards a model of L1 and L2 online reading comprehension
2019
The spread of information and communication technologies (ICTs) has been changing literacy practices and activities. Consequently, the traditional view of literacy as the ability to read and write needs to be revised to encompass new forms of literacy called e-literacy, or “digital/silicon/electronic literacies” (Murray & McPherson, 2006, p. 132) as well as “hyperreading” (Usó-Juan & Ruiz-Madrid, 2009, p. 59). The members of the 21st century “global”, “fluid” and “networked” (Jewitt, 2008) societies engage in activities that the access to the WWW makes possible. The aim of the paper is to discuss print-based models of reading, identify similarities and differences between online and offline…
The role of SAXS and molecular simulations in 3D structure elucidation of a DNA aptamer against lung cancer
2021
Aptamers are short, single-stranded DNA or RNA oligonucleotide molecules that function as synthetic analogs of antibodies and bind to a target molecule with high specificity. Aptamer affinity entirely depends on its tertiary structure and charge distribution. Therefore, length and structure optimization are essential for increasing aptamer specificity and affinity. Here, we present a general optimization procedure for finding the most populated atomistic structures of DNA aptamers. Based on the existed aptamer LC-18 for lung adenocarcinoma, a new truncated LC-18 (LC-18t) aptamer LC-18t was developed. A three-dimensional (3D) shape of LC-18t was reported based on small-angle X-ray scattering…

A multilevel latent growth modelling of the longitudinal changes in motivation regulations in physical education
2015
The purpose of this study was to examine individual- and classroom-level differences in the longitudinal change in motivational regulations during physical education students' transition from elementary (Grade 6) across middle school (Grades 7 to 9). A sample of 757 Finnish adolescents (M = 12.71, SD = 0.23) participated in this study. Participants of the study responded to questionnaires collected six times. A multilevel latent growth modelling approach was used to analyze the data. Results showed that motivational regulations in physical education developed at different rates during middle school. More specifically, students': (a) identified regulation increased across Grades 6 to 9; (b) …
Teachers' self-efficacy and the sources of efficacy: A cross-cultural investigation in Japan and Finland
2019
The study explores the extent and sources of Teachers’ Self-Efficacy (TSE) for inclusive practices among 261 Japanese and 1123 Finnish teachers. Measurement invariance was tested to ensure the chosen scales’ cross-cultural validity. In both countries, mastery experience was identified as the strongest of the four sources contributing uniquely to TSE. However, the two groups differed in how verbal persuasion predicted TSE. The findings indicate that the effects of the four sources on TSE depend strongly on sociocultural context, and that, in Japan, other sources may exert a powerful influence. Practical implications are discussed, with particular regard to teacher training programs. peerRevi…
Multilevel Latent Profile Analysis With Covariates : Identifying Job Characteristics Profiles in Hierarchical Data as an Example
2018
Latent profile analysis (LPA) is a person-centered method commonly used in organizational research to identify homogeneous subpopulations of employees within a heterogeneous population. However, in the case of nested data structures, such as employees nested in work departments, multilevel techniques are needed. Multilevel LPA (MLPA) enables adequate modeling of subpopulations in hierarchical data sets. MLPA enables investigation of variability in the proportions of Level 1 profiles across Level 2 units, and of Level 2 latent classes based on the proportions of Level 1 latent profiles and Level 1 ratings, and the extent to which covariates drawn from the different hierarchical levels of the…
Prezidenta Džo Baidena inugurācijas dienas tiešsaistes ziņu multimodālā analīze
2022
Amerikas Savienoto Valstu prezidenta inaugurācija ir viens no visvairāk dokumentētajiem notikumiem pasaulē, kuru plaši apraksta tiešsaistes mediju avoti. Ņemot vērā notikuma nozīmi un tiešsaistes ziņu lomu informācijas nodošanā mūsdienās, šī pētījuma mērķis bija parādīt lingvistisko un vizuālo līdzekļu integratīvo lomu nozīmes veidošanā, attēlojot Amerikas Savienoto Valstu prezidenta Džo Baidena inaugurāciju kā svarīgu notikumu tiešsaistes ziņās. Lai sasniegtu izvirzīto mērķi, tika apkopots un analizēts ziņu rakstu korpuss, kas publicēts dažādās starptautiskās ziņu vietnēs, izmantojot lingvistisko un vizuālo līdzekļu modeli un multimodālo diskursa analīzi. Rezultāti atklāja, ka izmantotie v…
