Training pre-service and in-service secondary school teachers: Analysis of changes in perceptions about quantum physics concepts and NoS views
2016
In this work we focus on the study of the changes in perceptions about Quantum Physics concepts and Nature of Science (NoS) Views of secondary school teachers attending three different typologies of professional development courses on Modern Physics . An open-ended questionnaire has been properly developed and administered in order to investigate Quantum Mechanics conceptual issues, NoS views and motivational aspects for all involved teachers. The same questionnaire has been submitted to the teachers both prior-to and after the courses. The analysis of teachers’ pre-instruction answers highlights that the majority of them show several difficulties on both conceptual knowledge and epistemolo…
The Effect of Music on Movement Perception: Synchresis in Hits for HIIT
2021
Hits for HIIT consists in a research-creation project aiming to produce both musical pieces and training exercises for, on the one hand, optimizing HIIT practice and, on the other, enriching scholarly research on the relations between music and sports. These questions and their related studies have highlighted music/movement relations and the way they are perceived. In this paper we would like to outline how we attempt to build a two-way dialogue between the production of music adapted to HIIT and the design of workouts based on the music.
Adaptación de tres variables contextuales en estudiantes universitarios argentinos
2017
Una de las dificultades que han presentado los estudios destinados a identificar las causas de deserción universitaria es la falta de consideración de variables sociales/contextuales que, según se ha demostrado en la literatura, se relacionan con el proceso de progresión de la carrera. Para la evaluación de dichas variables, el primer paso consiste en la adaptación de pruebas que permitan su medición. Por lo cual, el objetivo del presente trabajo consistió en la adaptación de las escalas de Apertura a la Diversidad, Percepción de Prejuicios y Discriminación y Experiencias Académicas. En este estudio participaron 1295 estudiantes que se encontraban cursando diferentes carreras en la Universi…
ERP denoising in multichannel EEG data using contrasts between signal and noise subspaces
2009
Abstract In this paper, a new method intended for ERP denoising in multichannel EEG data is discussed. The denoising is done by separating ERP/noise subspaces in multidimensional EEG data by a linear transformation and the following dimension reduction by ignoring noise components during inverse transformation. The separation matrix is found based on the assumption that ERP sources are deterministic for all repetitions of the same type of stimulus within the experiment, while the other noise sources do not obey the determinancy property. A detailed derivation of the technique is given together with the analysis of the results of its application to a real high-density EEG data set. The inter…
Attuning to a changing ocean
2020
The ocean is a lifeline for human existence, but current practices risk severely undermining ocean sustainability. Present and future social−ecological challenges necessitate the maintenance and development of knowledge and action by stimulating collaboration among scientists and between science, policy, and practice. Here we explore not only how such collaborations have developed in the Nordic countries and adjacent seas but also how knowledge from these regions contributes to an understanding of how to obtain a sustainable ocean. Our collective experience may be summarized in three points: 1) In the absence of long-term observations, decision-making is subject to high risk arising from na…
Powerful Pharma and Its Marginalized Alternatives?
2018
Abstract. Only little is known about the underpinning psychological processes that determine medical choices. Across four studies, we establish that conspiracy mentality predicts a preference for alternative over biomedical therapies. Study 1a (N = 392) and 1b (N = 204) provide correlational support, Study 2 (N = 185) experimentally tested the role of power: People who endorsed a conspiracy mentality perceived a drug more positively if its approval was supported by a powerless (vs. powerful) agent. Study 3 (N = 239) again showed a moderating effect of power and conspiracy mentality on drug evaluation by comparing analytic versus holistic approaches. These findings point to the consequences…
The publication of news about the results of R+D+I. How do Spanish researchers perceive it?
2018
El objetivo de este estudio es conocer cúal es la percepción que tienen los investigadores de las universidades españolas sobre el impacto que generan, sobre sus carreras profesionales, las noticias científicas que se publicancon los resultados de sus actividades de Investigación, Desarrollo e Innovación (I+D+i). Para ello, se han seleccionado los datos obtenidos por una encuesta online realizada en el año 2016 de 602 investigadores y profesionales de la comunicación científica de 20 universidades de España, teniendo único requisito que alguna de sus publicaciones hubiera sido objeto de —al menos— una nota de prensa difundida por su universidad en los últimos cinco años. Para el…
Usages et perceptions des T.I.C. à l'université
2002
The purpose is to analyze how students and teachers use and perceive ICT at the university. Both do not equally access to new techologies. The academic function of new technologies is questionable, according to the relative reject of the perspective of the virtual university.
Bot recognition in a Web store: An approach based on unsupervised learning
2020
Abstract Web traffic on e-business sites is increasingly dominated by artificial agents (Web bots) which pose a threat to the website security, privacy, and performance. To develop efficient bot detection methods and discover reliable e-customer behavioural patterns, the accurate separation of traffic generated by legitimate users and Web bots is necessary. This paper proposes a machine learning solution to the problem of bot and human session classification, with a specific application to e-commerce. The approach studied in this work explores the use of unsupervised learning (k-means and Graded Possibilistic c-Means), followed by supervised labelling of clusters, a generative learning stra…
ADHD and DAT1: Further evidence of paternal over-transmission of risk alleles and haplotype
2010
Contains fulltext : 87259.pdf (Publisher’s version ) (Closed access) We [Hawi et al. (2005); Am J Hum Genet 77:958-965] reported paternal over-transmission of risk alleles in some ADHD-associated genes. This was particularly clear in the case of the DAT1 3'-UTR VNTR. In the current investigation, we analyzed three new sample comprising of 1,248 ADHD nuclear families to examine the allelic over-transmission of DAT1 in ADHD. The IMAGE sample, the largest of the three-replication samples, provides strong support for a parent of origin effect for allele 6 and the 10 repeat allele (intron 8 and 3'-UTR VNTR, respectively) of DAT1. In addition, a similar pattern of over-transmission of paternal ri…
