Competitiveness and Sustainability in tourist firms and destinations

2020

Tourism is a major activity in the global economy, not only in terms of its economic impact but also its social and environmental implications. The management practices and processes adopted by tourist companies and destinations are very heterogeneous and have variable impacts on the triple-bottom-line sustainability (people, profit, planet) of the ecosystem. However, there is still only limited available knowledge about the value of different practices for promoting both sustainable development and greater competitiveness. This Special Issue includes papers that present new ideas, theories, advancements, experiences, evidence or methodologies that support the convergence of economic, socia…

On the use of unmanned aerial systems for environmental monitoring

2018

[EN] Environmental monitoring plays a central role in diagnosing climate and management impacts on natural and agricultural systems; enhancing the understanding of hydrological processes; optimizing the allocation and distribution of water resources; and assessing, forecasting, and even preventing natural disasters. Nowadays, most monitoring and data collection systems are based upon a combination of ground-based measurements, manned airborne sensors, and satellite observations. These data are utilized in describing both small-and large-scale processes, but have spatiotemporal constraints inherent to each respective collection system. Bridging the unique spatial and temporal divides that li…

Evaluación y clasificación de las revistas científicotécnicas españolas de Ciencias de la Actividad Física y el Deporte

2008

En este artículo se evalúan y clasifican las revistas españolas de Ciencias de la Actividad Física y el Deporte (CCAFD), atendiendo a su calidad global. Para ello se aplica un modelo de evaluación, validado con anterioridad, que combina 23 indicadores relativos a diferentes características de las revistas (formales, de contenido científico y difusión). De esta manera pueden clasificarse las publicaciones periódicas en cuatro categorías de calidad: ‘muy alta’, ‘alta’, ‘media’ y ‘baja’. Los resultados indican que ninguna de las 28 publicaciones existentes alcanza la categoría superior, el 25% obtiene una calidad ‘alta’, el 50% una calidad ‘media’ y otro 25% una calidad ‘baja’. Aunque se obser…

Modélisation de l'exposition au bruit en milieu urbain et études épidémiologiques : quelles sources sonores ?

2009

National audience; Epidemiological studies on noise in urban areas are mostly based on a modelling approach which only focuses on noise sources related to transportation and industries. Additional sources are likely to influence the ambient noise level, but the spatio-temporal influence they could have is rarely studied. The objective of this study is to identify urban noise sources that could improve environmental noise prediction and to quantify their respective contributions. An acoustic measurement campaign was conducted in frontage of 44 dwellings located on the city of Besancon (France). Measurements were compared to noise levels predictions produced from different noise maps in which…
