Factores facilitadores y barreras en la transición a la ciencia abierta: perspectiva de los agentes del sistema científico español
2022
This paper presents the results of a research study whose objective was to identify the facilitating factors and barriers that, in the opinion of representatives of the Spanish scientific community, impact the implementation of the new open science model in four areas: open access, open research data, research assessment and open peer review. A qualitative study was designed in which information was obtained through interviews with researchers, editors of scientific journals, representatives of assessment agencies and vice-chancellors, and through a focus group of librarians with expertise in aspects of open science. The enabling factors and barriers identified were related to the researche…
El frente popular: ¿Qué clase de acontecimiento? Historiografía y actualidad de las investigaciones sobre el Frente Popular
2016
The development of the historiography on the Popular Front has focused on three main fields, political history, social history and cultural history. However, the fragmentation of the object of study has hindered a more global reflection on the Popular Front, as one major event which constituted both a political and cultural project and an unprecedented social and political alliance with a broad popular movement. A fundamental event, embedded in the long life of French history, with significant consequences for the social area of the working class, the start of a new culture of social democracy French-style and as a reference which nourished the fights of the French Resistance as well as its…
Representações sociais, sens pratique, poder simbólico e o processo de construção do ser docente
2019
A partir de las elaboraciones teóricas de los fundadores del campo de investigación de las representaciones sociales, se pretende avanzar en la construcción de un diálogo entre esta teoría y la praxis social de Pierre Bourdieu, centrándose en la relación entre las representaciones sociales, la praxis sensorial (como manifestación del hábito) y el poder simbólico, dimensión ausente en el modelo moscoviciano. La base empírica a partir de la cual se desarrollan las reflexiones presentes en este artículo se apoya en investigaciones realizadas sobre el proceso de construcción del ser docente, en la realidad de algunas ciudades del nordeste brasileño. En este sentido, se destaca lo que se cree qu…
The use of barley straw residues to avoid high erosion and runoff rates on persimmon plantations in Eastern Spain under low frequency-high magnitude …
2016
[EN] Soil and water losses due to agricultural mismanagement are high and non-sustainable in many orchards. An experiment was set up with rainfall simulation at 78 mm h(-1) over 1 hour on 20 paired plots of 2 m(2) (bare and straw covered) in new persimmon plantations in Eastern Spain. Effects of straw cover on the control of soil and water losses were assessed. An addition of 60% straw cover (75 gm(-2)) resulted in delayed ponding and runoff generation and consequently reduced water losses from 60% to 13% of total rainfall. The straw cover reduced raindrop impact and thus sediment detachment from 1014 to 47 g plot(-1) h(-1). The erosion rate was reduced from 5.1 to 0.2 Mg ha-(1) h(-1). The …
Tablas y gráficos con R y R Studio
2021
¿Por qué este libro? es que no hay libros dedicados a ilustrar y mostrar cómo hacer tablas de contingencia y gráficos a partir de esas tablas usando R; hablando más específicamente usando expss y highcharter. Por otro lado, a partir de mi experiencia y de muchos años dedicado al mundo de la investigación y la docencia (mi hobbie personal) encontré el tiempo y la motivación para escribirlo. Quería crear un recurso que fuera diferente del resto de textos con el mismo contenido aproximado y porque creo que para que las ideas se difundan y adopten ampliamente, deben percibirse de manera amigable y fácil de entender, lo que tiene por qué estar reñido con una baja calidad científica y teórica. Si…
The measurement invariance of Job Diagnostic Survey (JDS) across three university student groups
2016
Purpose: The main purpose of this study is to apply a multigroup confirmatory analysis to examine the measurement invariance (MI) of the adapted version of the Job Diagnosis Survey (JDS) as a measurement tool that analyses the relationship between the features of teaching methodologies with university students’ motivation and satisfaction across data collected on different degrees and academic years. Design/methodology/approach: Confirmatory factor analysis was carried out using a multigroup structural equation model, using the program EQS 6.1 to test the invariance of the adapted version of JDS in a sample constituted by 535 student of a Spanish public university. The assessment of invaria…
Questions raised in science education : a Colombian-Spanish comparative study
2016
RESUMEN: La formulación de preguntas es un potente recurso para el aprendizaje de las ciencias. El objetivo del presente trabajo fue evaluar el desarrollo de la competencia metacognitiva por medio de la formulación de preguntas. En este estudio se usaron dos dispositivos experimentales de ciencias con un comportamiento inesperado. Se pidió a los participantes realizar preguntas destinadas a comprender su funcionamiento. La evaluación contrastó el desempeño de estudiantes colombianos con estudiantes españoles equivalentes. Los resultados mostraron que los colombianos formulan significativamente más preguntas en general, y más preguntas de alta calidad, que los estudiantes españoles. Se concl…
Effects of Resistance Training of Peripheral Muscles Versus Respiratory Muscles in Older Adults With Sarcopenia Who are Institutionalized: A Randomiz…
2018
[EN] This study compares the effects of two resistance training programs in peripheral and respiratory musculature on muscle mass and strength and physical performance and identifies the appropriate muscle mass parameter for assessing the intervention effects. Thirty-seven institutionalized older Spanish adults with sarcopenia were analyzed: control group (n = 17), respiratory muscle training group (n = 9), and peripheral muscle training group (n = 11). Measured outcomes were appendicular skeletal muscle mass (ASM/height(2), ASM/weight, and ASM/BMI), isometric knee extension, arm flexion and handgrip strength, maximal inspiratory and expiratory pressures, and gait speed pre- and postinterve…

A Statistical Approach for A-Posteriori Deployment of Microclimate Sensors in Museums: A Case Study
2022
[EN] The deployment of sensors is the first issue encountered when microclimate monitoring is planned in spaces devoted to the conservation of artworks. Sometimes, the first decision regarding the position of sensors may not be suitable for characterising the microclimate close to climate sensitive artworks or should be revised in light of new circumstances. This paper fits into this context by proposing a rational approach for a posteriori deployment of microclimate sensors in museums where long-term temperature and relative humidity observations were available (here, the Rosenborg Castle, Copenhagen, Denmark). Different statistical tools such as box-and-whisker plots, principal component …
