Half a century of Anales de Pediatría. Evolution of its main bibliometric indicators in the Web of Science and Scopus international databases
2019
Purpose: To analyze the coverage and main bibliometric indicators of Anales de Pediatría in Scopus and Science Citation Index Expanded of the Web of Science (SCIE) databases. Material and method: The evolution of the journal production was identified according to the document types, collaboration indexes between authors and institutions, and citations, and impact indicators (number of citations, impact factor, 5-years impact factor and without self-citations, Scimago Journal Rank, quartile, h-index and most cited works). Results: A total of 10,128 papers were included in Scopus (a mean of around 225 per year) and 1861 in SCIE (a mean of around 207 per year). The index of collaboration was 4…
Ionization and scintillation response of high-pressure xenon gas to alpha particles
2013
High-pressure xenon gas is an attractive detection medium for a variety of applications in fundamental and applied physics. In this paper we study the ionization and scintillation detection properties of xenon gas at 10 bar pressure. For this purpose, we use a source of alpha particles in the NEXT-DEMO time projection chamber, the large scale prototype of the NEXT-100 neutrinoless double beta decay experiment, in three different drift electric field configurations. We measure the ionization electron drift velocity and longitudinal diffusion, and compare our results to expectations based on available electron scattering cross sections on pure xenon. In addition, two types of measurements add…
Indigenous Research and Romantic Nationalism
2016
In recent years, “indigenous research” and “indigenous methods” have become prominent themes in the general field of qualitative methodology. These ideas and their implications raise serious questions for the wider conduct of social research. We will outline some of those ideas, subjecting them to scrutiny, and ultimately using them to question the rise of Romanticism in contemporary social methodology. We develop these ideas to question the contemporary emphasis on the personal and the experiential in current methodological commentary.
Optimization of cogging force in a linear permanent magnet generator for the conversion of sea waves energy
2015
In this paper an approach to the optimization of cogging force in a linear permanent magnet generator for the conversion of sea waves energy is presented. We have optimized the cogging force of a linear permanent magnet generator by using a 3D FEM parametric simulation. Several possible design solutions have been computed. A generator has been built and the results of the minimization procedure has been experimentally validated.
Diversity in Coherence : Strengths and Opportunities of Three Programs
2017
Author's accepted version (post-print). Although teacher educators may perceive their program and courses to be coherent, the question remains to what extent student teachers also are able to perceive the linkages within their programs. Coherence within teacher education programs is important for teacher candidates to build understanding of teaching. Our study draws upon survey data from 269 teacher candidates, in three different teacher education programs, located in three different countries (Norway, Finland, United States [California]) and compares these candidates’ perceptions of the coherence of their teacher education programs. Candidates from a program that has explicitly been workin…
Diseño e implementación de una secuencia de enseñanza para introducir los conceptos de sustancia y compuesto químico
2012
Este estudio propone la implementación de una secuencia didáctica para facilitar el aprendizaje de los conceptos de sustancia, sustancia simple y compuesto en educación secundaria. Para su elaboración se ha partido del análisis histórico y las concepciones alternativas más frecuentes de los estudiantes respecto a estos conceptos. Su evaluación se ha realizado mediante un estudio comparativo entre grupos de alumnos que la han utilizado en clase y grupos que han seguido un método de enseñanza tradicional. Los resultados muestran que la selección de contenidos y las estrategias utilizadas en una secuencia de enseñanza de orientación constructivista ofrece a los estudiantes mayor capacidad de a…
Les incitations à l'innovation dans le secteur privé
2011
En ligne sur http://www.cairn.info/load_pdf.php?ID_ARTICLE=REL_792_0045; International audience; L'innovation est devenue un facteur clé de la croissance économique. La question des incitations à l'innovation au sein des entreprises est donc primordiale. Dans ce papier, nous nous intéressons au type d'incitations monétaires reçues par les inventeurs au sein des entreprises avec une attention particulière à la mobilité inter-entreprise de ces derniers. Les résultats montrent un rendement salarial positif pour les inventeurs, celui-ci est plus important pour les inventeurs ayant connu une mobilité inter-entreprise, ce qui pourrait suggérer que les entreprises sont prêtes à payer les connaissa…
Effects of the Best Possible Self intervention: A systematic review and meta-analysis
2019
The Best Possible Self (BPS) exercise promotes a positive view of oneself in the best possible future, after working hard towards it. Since the first work that attempted to examine the benefits of this intervention in 2001, studies on the BPS have grown exponentially and, currently, this is one of the most widely used Positive Psychology Interventions. However, little is yet known about its overall effectiveness in increasing wellbeing outcomes. Thus, the aim of this meta-analysis is to shed light on this question. A systematic literature search was conducted, and 29 studies (in 26 articles) met the inclusion criteria of empirically testing the intervention and comparing it to a control con…
The Hydrothermal System of Solfatara Crater (Campi Flegrei, Italy) Inferred From Machine Learning Algorithms
2019
Two machine learning algorithms were applied to three multivariate datasets acquired at Solfatara volcano. Our aim was to find an unbiased and coherent synthesis among the large amount of data acquired within the crater and along two orthogonal vertical NNE- and WNW-trending cross-sections. The first algorithm includes a new approach for a soft K-means clustering based on the use of the silhouette index to control the color palette of the clusters. The second algorithm which uses the self-organizing maps incorporates an alternative method for choosing the number of nodes of the neural network which aims to avoid the need for downstream clustering of the results of the classification. Both m…
Against the flow in data collection: How data triangulation combined with a ‘slow’ interview technique enriches data
2017
Capturing the voices of the ‘disadvantaged’ in society may often be difficult to achieve. In this article, we argue that the combination of data triangulation and a ‘slow’ interview technique may be a good method when the target group is vulnerable people who may find the interview challenging. Data triangulation can reveal a social phenomenon’s complexity by providing a fuller picture, while in-depth interviews and a ‘slow’ interview technique can enhance data quality. We present an alternative to what we perceive as being dominant and tacit support for use of voice recordings in interview-based studies, thus our research approach goes against the current flow in the research community. I…
