Does corn market uncertainty impact the US ethanol prices?
2018
The growing interest in biofuel as a green energy source has intensified the linkages between corn and ethanol markets, especially in the United States that represents the largest producing and exporting country for ethanol in the world. In this study, we examine the effect of corn market uncertainty on the price changes of US ethanol applying a set of GARCH-jump models. We find that the US ethanol price changes react positively to the corn market volatility shocks after controlling for the effect of oil price uncertainty. In addition, we document that the impact of corn price volatility on the US ethanol prices appears to be asymmetric. Specifically, only the positive corn market volatilit…
Implicación de la escara miocárdica en la predicción y tratamiento de la taquicardia ventricular postinfarto
2017
INTRODUCCIÓN Y OBJETIVOS: La taquicardia ventricular (TV) es una arritmia peligrosa y una causa importante de muerte súbita en pacientes que han padecido un infarto previo. Las escaras ventriculares tras infarto son un sustrato que favorece la reentrada eléctrica, que es el mecanismo más frecuente de taquicardia ventricular. Intentar entender el potencial arritmogénico de la escara ayudaría por una parte a identificar precozmente pacientes en riesgo de padecer taquicardias ventriculares de lo que podrían derivar actuaciones clínicas, y por otra parte, su tratamiento una vez se ha presentado la arritmia, modificando las características de dicha escara mediante ablación con catéter. Esta tesi…
An Atypical Case of Taravana Syndrome in a Breath-Hold Underwater Fishing Champion: A Case Report
2013
Dysbaric accidents are usually referred to compressed air-supplied diving. Nonetheless, some cases of decompression illness are known to have occurred among breath-hold (BH) divers also, and they are reported in the medical literature. A male BH diver (57 years old), underwater fishing champion, presented neurological disorders as dizziness, sensory numbness, blurred vision, and left frontoparietal pain after many dives to a 30–35 meters sea water depth with short surface intervals. Symptoms spontaneously regressed and the patient came back home. The following morning, pain and neurological impairment occurred again and the diver went by himself to the hospital where he had a generalized to…
Sensitivity of bipartite network analyses to incomplete sampling and taxonomic uncertainty
2023
Bipartite network analysis is a powerful tool to study the processes structuring interactions in ecological communities. In applying the method, it is assumed that the sampled interactions provide an accurate representation of the actual community. However, acquiring a representative sample may be difficult as not all species are equally abundant or easily identifiable. Two potential sampling issues can compromise the conclusions of bipartite network analyses: failure to capture the full range of interactions (sampling completeness) and use of a taxonomic level higher than species to evaluate the network (taxonomic resolution). We asked how commonly used descriptors of bipartite antagonisti…
Awareness and knowledge of cyberethics: A comparative study of preservice teachers in Malta, Norway, and Spain
2021
This paper explores the awareness and knowledge of cyberethics held by pre-service teachers across three European countries. The study was conducted via an online survey and yielded 1,131 responses from pre-service teachers in Malta, Norway, and Spain. The facets of cyberethics included in this study focused on behaving responsibly online, safeguarding privacy, respecting copyright, seeking consent of friends before posting images or videos on social media platforms, and considering their professional identity as future teachers when posting online. The findings indicate that pre-service teachers reported relatively similar levels of competence in applying copyright and respecting privacy r…
Socialization Into Teaching Physical Education – Acculturative Formation of Perceived Strengths
2015
1. IntroductionIt is common that physical education (PE) in primary schools is taught by generalist class teachers. They have been found to possess strong socially constructed beliefs about teaching and their teaching competencies already before they enter formal teacher preparation. These beliefs act as filters when acquiring and interpreting new information thus influencing what is learned during the formal teacher preparation (Capel & Katene, 2000; Curtner-Smith, 2001; Doolittle, Dodds, & Placek, 1993; Hutchinson, 1993; Lawson, 1983; Lortie, 1975; Matanin & Collier, 2003; Pajares, 1992; Placek, Dodds, Doolittle, Portman, Ratliffe & Pinkham, 1995; Randall & Maeda, 2010; Richardson, 2003).…
Are quality management practices enough to improve process innovation?
2015
The popularity of quality management as a system for continuous improvement has not been accompanied by deep theoretical understanding of its effects on process innovation. In this work, the resource-based view serves as the basis for the construction of a model designed to explain the effects of quality management practices (QMP) on process innovation performance and the mediating role of dynamic capabilities in this relationship. The empirical data were analysed using the structural equation modelling technique by examining 6 competing models that represent full, partial mediation and non-mediation relationships on a sample of 550 Spanish industrial companies. The findings indicate that t…
Revista complutense de educación
2015
Resumen basado en el de la publicación Número Especial: TIC en Educación Existe un interés pedagógico por transformar las tecnologías de la información y comunicación en tecnologías para el aprendizaje y el conocimiento. Se presentan una serie de contribuciones didácticas asociadas al uso de blogs en la Educación Superior a partir de una experiencia de innovación educativa por proyectos llevada a cabo por un grupo de profesores universitarios entre los años 2009 y 2013. Tanto el profesorado como el alumnado participante en las asignaturas donde se ha puesto en práctica el edublog, lo verifican como un recurso útil para conformar entornos virtuales de enseñanza y aprendizaje gracias a las mú…
El lenguaje de las tecnologías en la formación de maestros

Este artículo se encuentra disponible a texto completo en la siguiente URL: https://revistas.uam.es/tendenciaspedagogicas/article/view/tp2020_36_09 Este número monográfico de la revista Tendencias Pedagógicas lleva por título "La alfabetización académica". Este trabajo pretende reflexionar sobre las implicaciones educativas que hoy día tiene la competencia mediática en los procesos de enseñanza-aprendizaje. La evolución de las TIC y, sobre todo, de la tecnología móvil, ha provocado una revolución comunicativa educativa y social que afecta al mundo educativo; los contextos edu-cativos son cambiantes y evolucionan rápido, teniendo que adaptarse a los cambios socioculturales, tecnológi-cos, et…
Educatio siglo XXI : revista de la Facultad de Educación
2018
El presente estudio describe la competencia digital en el tratamiento de contenidos de Ciencias Sociales de futuros maestros. Para ello se recurre al TPACK (Technological Pedagogical Content Knowledge) y se analizan los resultados de un cuestionario sobre las concepciones al respecto de 153 estudiantes del Grado de Magisterio en Educación Primaria. Las conclusiones confirman un mayor autoconocimiento de contenidos pedagógicos o tecnológicos, frente a los disciplinares, lo que imposibilita, siguiendo la aplicación del modelo, el desarrollo de una competencia digital docente efectiva para el desarrollo de una didáctica crítica en Ciencias Sociales. The present study describes the use of digit…
