An integrated modelling and remote sensing approach for hydrological study in arid and semi-arid regions: the SUDMED Program
2008
International audience; Recent efforts have been concentrated in the development of models to understand and predict the impact of environmental changes on hydrological cycle and water resources in arid and semi-arid regions. In this context, remote sensing data have been widely used to initialize, to force, or to control the simulations of these models. However, for several reasons, including the difficulty in establishing relationships between observational and model variables, the potential offered by satellite data has not been fully used. As a matter of fact, a few hydrological studies that use remote sensing data emanating from different sources (sensors, platforms) have been performe…
Distribution and sources of bulk organic matter (OM) on a tropical intertidal mud bank in French Guiana from elemental and isotopic proxies
2014
International audience; The mobile French Guiana coast is a shoreface region downdrift of the Amazon River, where enormous quantities of inorganic and organic materials are exchanged with the Atlantic Ocean. The rapid accumulation of these materials forms highly unstable shore-attached mud banks, which can be temporally emerged and then rapidly colonized and stabilized by microphytobenthos and opportunistic mangroves (i.e. Avicennia germinans). Mud banks are preferential sites for the accumulation and significant remineralization of organic matter (OM) due to intense erosion/deposition cycles and potential biological colonization. The distribution and sources of bulk sedimentary OM were cha…
Competence as a Career Opportunity's Guarantor
2015
<p><em>The aim of the research is to investigate the essence of the notion ”competence” and the differences in the usage of the </em><em>career's terminology in semantic, methodological and pragmatic areas in academic theories of the second part of the 20 century; to work out evaluation criteria by comparing the succession of the </em><em>notions capacity. The research is based on the Latvian and international sources of scientific literature – books, magazines, sources in digital form, and etc. A </em><em>personality was </em><em>investigated holistically </em><em>( Džarviss (Jarvis, 2010); Devis (Dove, 1976); Kross (C…
Assessment of Researchers Through Bibliometric Indicators: The Area of Information and Library Science in Spain as a Case Study (2001–2015)
2018
Research activities are subject to constant processes of evaluation, which increasingly include the use of bibliometric indicators to support decision-making. This paper presents a model for the individual evaluation of different facets of researchers' work and discusses the interest in using “control” parameters to identify deviations suggesting inappropriate conduct. The proposed model is illustrated through an empirical example that analyzes the activity of Spanish researchers in the area of Library and Information Science. There are important differences among the most productive authors, and in many cases, there is no association between the degree of participation in high-impact journ…
Effect of a Service-Learning Program on the Active Lifestyle of Children with Autism Spectrum Disorder: A Pilot Study
2020
Background: active lifestyles and Physical Activity (PA) are closely related to health. Healthy habits such as being physically active should be consolidated during childhood. Children with Autism Spectrum Disorders (ASD) present fewer opportunities to be involved in PA. For this reason, we conducted a Service-Learning (SL) program to enhance the possibility of participating ASD children enjoying PA sessions. The aim of this study was to analyze and describe the evolution in terms of the frequency and intensity of PA performed by ASD children who participated in the SL program. Methods: we used a quasi-experimental design. The sample was formed by 26 children with ASD (Experimental group: n…
Investigación española en las áreas de adicciones y de trastornos de la alimentación: análisis de la producción, colaboración e impacto científico (1…
2021
Las adicciones y los trastornos de la alimentación constituyen uno de los principales problemas de salud en la sociedad contemporánea al que se destinan gran cantidad de recursos destinados a la investigación para su prevención y tratamiento. Objetivos. Analizar la investigación española en el área de adicciones y trastornos de la alimentación desde que se publicó el primer trabajo recogido en bases de datos bibliográficas y desde una perspectiva bibliométrica. Metodología. Para obtener la información necesaria se consultaron las bases de datos Web of Science, Scopus y bases de datos del CSIC. Se elaboró un perfil de búsqueda específico. Se obtuvieron indicadores bibliométricos de producció…
Teoría de la educación : educación y cultura en la sociedad de la información
2008
La educación para la igualdad requiere de la implicación de todas y cada una de las agencias que participan de este proceso. En este trabajo hemos querido conocer en qué medida los videojuegos más vendidos y utilizados por la población infantil y juvenil transmiten contenidos que contribuyen a su educación para la igualdad o, por el contrario, la dificultan. Para ello hemos analizado el contenido de los diez videojuegos más jugados por menores y adolescente, atendiendo a los valores y disvalores que transmiten, centrando nuestra atención en la representación de modelos de mujer y roles de género. Por último, hemos tratado de establecer una serie de conclusiones y orientaciones pedagógicas, …
Geriatric Care Resources in Poland and the Czech Republic - Comparative Analysis
2016
The demographic forecasts show that by 2035. subpopulation of people aged 65+ in Poland and in Czech Republic will grow rapidly. The increase in the number of the oldest has in turn a significant impact on even faster growth of demand for the provision of care and grooming, and hence - for the resources of geriatric care. Demographic aging of the population is one of the social processes focused the attention of researchers from many disciplines: economists, specialists in medicine and public health, social politicians and sociologists. Demographic aging of the population is not unexpected process; it is determined by several factors, especially the increasing of life expectancy. High impac…
Sustainability Assessment of Agricultural Systems in Paraguay: A Comparative Study Using FAO’s SAFA Framework
2019
Sustainability is a topic that is at the center of current discussions in the political, economic, social, and environmental fields. For its analysis, an integral and multidisciplinary vision is needed. This work aims to assess the sustainability of agricultural systems in Paraguay through a comparison applying SAFA (Sustainability Assessment of Food and Agriculture Systems) indicators. The research focuses on 15 case studies on the territory of the Eastern Region of Paraguay divided into five classes of agricultural systems: agribusiness, conventional peasant family farming, agroecological peasant family farming, neo-rural farming, and indigenous agriculture. Data were collected through in…
The importance of social value in agroecological farms: adjusting the common good balance sheet to improve their sustainable management
2021
Organic farming offers the producers the possibility of focusing on their business while obtaining a competitive advantage. Nevertheless, this is centered in specific activities of the production process, thus only creating environmental value. Therefore, it is not an approach based on sustainability. As a consequence of this, it becomes necessary to enlarge this approach toward people (social value) and profitability (economic value). The objective of this work is to describe a tool based on the Economy for the Common Good model applied to the agroecological sector. We propose to adapt the Common Good Matrix to the characteristics of agroecological farms to offer a useful tool to manage an…
