Main intrinsic factors driving land grabbing in the African countries’ agro-food industry
2022
Land grabbing is a phenomenon that has spread widely over the last two decades and which involves rich and emerging countries and international companies as protagonists in the large-scale acquisition of land in developing countries. Through the development of an econometric model that takes into account the annual size of land grabbing in the African countries, the research aims to understand the main intrinsic factors, linked to the hosting countries, that guide the large-scale acquisition of land by foreign investors. Results show that the presence of a high debt towards foreign organisations, the high availability of virgin lands, the strong vocation of the hosting country for the culti…
The contribution of human migration to tourism: The VFR travel between the EU28 member states
2017
This study explores the correlation between human migration and that part of tourism due to people visiting friends and relatives in a foreign country. We first compared the network structure of migration stocks and tourism flows between the 28 member countries of the European Union over the period 2000–2012. Then, we performed several econometric analyses to study the main tourism determinants and the correlations between migration to tourism. The paper derives from the discussion of the results an estimate of the contribution to the overall tourism phenomenon due to visiting friends and relatives. Complex network analysis and gravity models were the investigation methods preferred.
UNA PROPUESTA EXPERIMENTAL EN LA ENSEÑANZA DE LA MÚSICA EN SECUNDARIA
2015
<p>En el presente artículo se pretende describir una experiencia enfocada hacia la enseñanza de la Música en Secundaria, aplicando el Método Cooperativo por Proyectos. Se trata de determinar su eficacia y pertinencia en el marco del aprendizaje por competencias mediante un proceso de investigación-acción que se llevó a cabo con alumnos de 2º y 3º de ESO. Para comprobar su efectividad se ha contrastado dicho método con otro de referencia: la Clase Magistral. Las conclusiones se justifican mediante un análisis estadístico, realizado de manera cualitativa y cuantitativa.</p><p>La propuesta se realiza con el fin de comprobar si ésta experiencia da respuesta a las necesidades …
Influence of storage and in vitro gastrointestinal digestion on totqal antioxidant capacity of fruit beverages
2011
Eight fruit beverages containing grape, orange and apricot, with/without iron and/or zinc and with/without milk added were analyzed for total antioxidant capacity (ORAC and TEAC methods), ascorbic acid content, and total polyphenols. The influence of cold storage (2-4 degrees C) during the product shelf-life (135 days) and antioxidant capacity after an in vitro gastrointestinal digestion were evaluated. Antioxidant capacity for all beverages together increased significantly (p < 0.05) at the end of storage (16.4% and 12.8% for ORAC and TEAC, respectively), whereas ascorbic acid remained stable. Regarding in vitro digestion, antioxidant values of bioaccessible fractions of fruit beverages in…
Hypothetical Investment Bias
2018
Young, entrepreneurial firms are particularly dependent on external investors to sustain their development. Are non-binding equity investment commitments informative? Our large sample evidence in the context of equity crowdfunding shows that only 18% of non-binding commitments made by investors in entrepreneurial firms are actually invested. The evidence is consistent with hypothetical bias. Hypothetical bias is significantly less pronounced among women, and among investors with greater social capital, proxied by education and wealth. While investment intentions are only partially reliable at the individual level, the aggregate amount of collected investment intentions is a strong predictor…

Educación artística : revista de investigación
2020
Resumen: A modo de introducción, la productora de animación Disney tiene un gran potencial, desde sus inicios en la década de los años veinte del siglo pasado, para transmitir unos mensajes ideológicos y doctrinales en quienes consumen sus largometrajes, generalmente quienes se encuentran en la infancia. De entre la pluralidad de ideas destaca la mentalidad maniquea que construye la sociedad en base al binomio bondad-maldad negando en la cotidianeidad comportamientos intermedios a esta dualidad; todo ello recurriendo a la imagen como recurso visual de comunicación. Esta aparece como constante en las figuras malvadas que diseña para sus largometrajes y se relaciona con el concepto de estétic…
Adjusting to Climate Change: Implications of Increased Variability and Asymmetric Adjustment Costs for Investment in Water Reserves
1997
Abstract In this paper we study the determination of optimal water storage capacity in a region, taking into account that the supply of the resource, the flow into the reserve, is uncertain, that a measure of the uncertainty, the variance, is likely to increase with climate change, that building capacity is costly, and that the development of water resources may entail alsoenvironmental costs. We find that water storage capacity in the long run ispositivelyrelated to increases in uncertainty if the marginal benefit of water withdrawal isconvexand that, for the case of costly reversibility of investment, a range of inaction for investment appears, and the stability of water storage capacity …
Environmental Benefits of Wastewater Treatment: An Economic Valuation
2009
The need of economic research into the design and implementation of policies for the efficient management of water resources has been emphasized by the European Water Framework Directive (Directive 2000/60/UE). The efficient implementation of policies to prevent the degradation and depletion of water resources requires determining their value in social and economic terms and incorporating this information into the decision-making process. A process of wastewater treatment has many associated environmental benefits. However, these benefits are often not calculated because they are not set by the market. Nevertheless, the valuation of these benefits is necessary to justify a suitable investme…
