Las preguntas, nexo entre investigación y enseñanza.
2012
Las situaciones de aula seleccionadas sirven, en nuestra investigación, como punto de partida para formular preguntas pertinentes que ayuden al profesorado universitario a organizar su enseñanza y lleven al alumnado a elicitar o reconstruir, con ayuda de sus profesores, las teorías que orientan la actividad de los maestros. En este caso, los principios teóricos, que justifican y dan sentido a la forma que tiene la maestra de enseñar el lenguaje. Los materiales didácticos construidos desde el análisis de situaciones de aula de Educación Infantil constituye el corpus básico para llevar a cabo el trabajo que presentamos.

Runoff initiation, soil detachment and connectivity are enhanced as a consequence of vineyards plantations.
2017
[EN] Rainfall-induced soil erosion is a major threat, especially in agricultural soils. In the Mediterranean belt, vineyards are affected by high soil loss rates, leading to land degradation. Plantation of new vines is carried out after deep ploughing, use of heavy machinery, wheel traffic, and trampling. Those works result in soil physical properties changes and contribute to enhanced runoff rates and increased soil erosion rates. The objective of this paper is to assess the impact of the plantation of vineyards on soil hydrological and erosional response under low frequency - high magnitude rainfall events, the ones that under the Mediterranean climatic conditions trigger extreme soil ero…
An economic, perception and biophysical approach to the use of oat straw as mulch in Mediterranean rainfed agriculture land
2017
[EN] Soil erosion is a key cause of land degradation in agriculture lands; and it is a worldwide threat that must be solved by means of nature-based strategies to be able to achieve sustainability. The use of mulches can be a solution, but there is a lack of information on long-term effects of the use of straw. Furthermore, little is known about the perception of farmers and the economic cost on the implantation of straw as a conservation measure. Eight paired plots were selected in Sierra de Enguera on an agriculture field to determine the effect of straw cover on soil erosion. Four plots were tilled three times per year (Control) and four plots were not ploughed and 0.125 kg m(-2) y(-1) o…
La opinión de los graduados europeos sobre la universidad cinco años después de haber finalizado sus estudios
2011
In today¿s knowledge society, in which university graduates are required to obtain new abilities to adjust to the demands of the labour market, the figure of the ¿flexible professional¿ has emerged. Universities are not immune to these changes and are proposing modifications to the curricula. In this paper, we attempt to depict the views of university graduates regarding their university five years after completing their studies. Information about graduates¿ educational experience is crucial to educational managers in charge of designing curricula and educational policies. The data used in this paper are obtained from the REFLEX Survey.
Long-term organic farming on a citrus plantation results in soil organic carbon recovery
2019
[ES] Se ha demostrado que el manejo del suelo bajo agricultura ecológica puede aumentar el contenido de carbono orgánico en el suelo moderando el incremento de los gases de efecto invernadero, pero hasta la fecha las evaluaciones cuantitativas basadas en mediciones a largo plazo han sido escasas, especialmente bajo condiciones mediterráneas. En esta investigación se examinaron los cambios en el contenido de carbono orgánico como respuesta a la agricultura ecológica con cobertura vegetal en una plantación de cítricos en el área mediterránea, utilizando una base de datos de 21 años. El incremento de contenido de carbono orgánico en el suelo fue más evidente tras cinco años desde el cambio del…
Educación XX1 : revista de la Facultad de Educación
2017
Introducción: La institucionalización del Aprendizaje-Servicio (ApS) en la universidad recomienda, en primer lugar, el análisis de la cultura docente del profesorado y su actitud hacia la innovación. Precisamente, lo que este trabajo pretende es aportar un modelo teórico integrador desarrollando tres escalas de evaluación, contrastadas a través de pruebas estadísticas, para el contexto de la enseñanza universitaria en España. Metodología: A fin de elaborar el modelo de medida se aplicaron tres escalas a 1903 profesoras y profesores de 6 universidades españolas: una escala de práctica docente (18 ítems), otra sobre compromiso social de la Universidad (9 ítems), y una tercera, sobre prácticas…
Innovative teaching strategies in sciences teaching. Case study: teachers of the Rural Education Foundation of Valencia (1958-1985).
2017
Este trabajo aborda la reintroducción de estrategias didácticas en ciencias experimentales en el mundo rural de la provincia de Valencia que tuvo lugar a partir de los años 60 del siglo pasado. Para ello se han analizado documentos relativos al Patronato de Educación Rural (1958-1985), organismo dependiente de la Diputación de Valencia constituido con el objetivo de mejorar la educación en zonas rurales de la provincia. La metodología utilizada en la investigación se fundamenta en el método analítico descriptivo mediante la búsqueda, revisión y análisis de fuentes históricas e iconográficas depositadas en el Archivo de la Diputación Provincial de Valencia. La investigación pretende poner de…
The Logic of Gift: Inspiring behavior in organizations beyond the limits of duty and exchange
2016
[EN] Giving without the expectation of reward is difficult to understand in organizational contexts. In opposition to a logic based on self-interest or a sense of duty, a "logic of gift" has been proposed as a way to understand the phenomenon of free, unconditional giving. However, the rationale behind, and effects of, this logic have been under-explored. This paper responds by first clarifying the three logics of action¿the logic of exchange, the logic of duty, and the logic of gift¿and then explains how their balanced integration promises to enhance organizational life and outcomes. Having explicated the unique character and contributions of the logic of gift, the paper further suggests p…
Cross-sectional assessment of nut consumption and obesity, metabolic syndrome and other cardiometabolic risk factors: the PREDIMED study
2013
INTRODUCTION: Prospective studies have consistently suggested that nut consumption is inversely related to fatal and non-fatal coronary heart disease. Limited data are available on the epidemiological associations between nut intake and cardiometabolic risk factors. OBJECTIVE: To evaluate associations between frequency of nut consumption and prevalence of cardiometabolic risk factors [obesity, metabolic syndrome (MetS), type-2 diabetes, hypertension, and dyslipidemia] in a Mediterranean population at high cardiovascular risk. MATERIALS AND METHODS: Cross-sectional study of 7,210 men and women (mean age, 67 y) recruited into the PREDIMED study. MetS was defined by the harmonized ATPIII and I…
Do different models induce changes in mortality indicators? That is a key question for extending the Lee-Carter model
2021
[EN] The parametric model introduced by Lee and Carter in 1992 for modeling mortality rates in the USA was a seminal development in forecasting life expectancies and has been widely used since then. Different extensions of this model, using different hypotheses about the data, constraints on the parameters, and appropriate methods have led to improvements in the model's fit to historical data and the model's forecasting of the future. This paper's main objective is to evaluate if differences between models are reflected in different mortality indicators' forecasts. To this end, nine sets of indicator predictions were generated by crossing three models and three block-bootstrap samples with …
