Relevance of Social, Economic, and Environmental Impacts on Residents’ Satisfaction with the Public Administration of Tourism

Those in charge of tourism destinations face the need to create tourism development models compatible with the essence of the localities that they manage. These models have to be sustainable, both environmentally and socially, and also must become drivers of the local economy. However, tourists also generate negative impacts in the locality which, when they are perceived by the residents, can give rise to a rejection of visitors. Hence, improving the tourism management is necessary. This is why to know the residents’ perceptions about the impacts of tourism is essential. Moreover, measuring the impact effects on their satisfaction with the public administration of the destination can be of great usefulness. This study falls into this research line, as it proposes a model to measure these impacts and their effect on satisfaction. To do so, an empirical study is performed among residents in the city of Seville (southern Spain, one of the most visited destinations in the world), based on subjective economic, social, and environmental indicators. The results show that the citizens value three types of impacts, the social impact coming after the economic impact as to its influence on their satisfaction with the administration. Based on this, we postulate that the efforts made to attract events to the city, or to improve connections to access a broader market, must be approached as public procurements in which selection criteria that are compatible with the destination’s positioning and strategy prevail. Social and environmental criteria should be considered among these criteria

Chemical composition of lipophilic extractives from non-woody plants used for manufacturing high-quality papers

The chemical composition of lipophilic extractives from fibers of three annual plants, namely hemp (Cannabis sativa), flax (Linum usitatissimum) and kenaf (Hibiscus cannabinus) that are commonly used for high quality paper pulp production was studied. The cloroform soluble fractions of the acetone extracts of the fibers were analyzed by gas chromatography-mass spectrometry. The main compounds identified were series of n-alkanes, n-fatty acids, n-aldehydes, n-fatty alcohols and waxes. On the other hand, free and esterified sterols and triterpenols, steroid hydrocarbons, steroid and triterpenoid ketones, as well as sterol glycosides were also found in the fibers studied here.A.G. acknowledges a "Ramón y Cajal" contract of the Spanish MCYT.

Chemical composition of lipophilic extractives from sisal (Agave sisalana) fibers

Instituto de Recursos Naturales y Agrobiología de Sevilla, CSIC, PO Box 1052, E-41080 Seville, Spain. Corresponding author, E-mail: [email protected] (A. Gutiérrez)The chemical composition of lipophilic extractives from sisal (Agave sisalana) fibers, which are used for high-quality paper pulp production was studied. The lipophilic extract, which accounted for 0.5 % of total sisal fiber weight, was analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS) using short- and medium-length high temperature capillary columns, respectively. For a more detailed characterization, the extract was fractionated by solid-phase extraction and the fractions obtained were analyzed by GC and GC/MS. The most predominant compounds identified were fatty acids (30% of total lipids) including α- and -hydroxyfatty acids, fatty alcohols (20%), free sterols (11%), alkanes (11%) and a series of ferulic acid esters of long chain alcohols and -hydroxyfatty acids (10%). Additionally, steroid hydrocarbons and ketones, monoglycerides, aldehydes, waxes, and sterol glycosides were also found together with minor amounts of diglycerides, and sterol esters.This study has been supported by the Spanish Ministerio de Ciencia y Tecnología (MCYT) (projects AGL2002-00393 and AGL2005-01748) and EU project (BIORENEW, NMP2-CT-2006-026456).

Convergencia de redes inalámbricas basadas en tecnología MESH como solución de conectividad en entornos empresariales

La tecnología inalámbrica de redes mallada es una mezcla de tecnologías que se integran para brindar soluciones de conectividad y de convergencia de servicios a zonas que por su ubicación geográfica y su requerimiento tecnológico de tráfico requieren de su funcionalidad. Esta tecnología para su funcionamiento integra las dos topologías de redes inalámbricas conocidas que son: la ad–hoc (peer to peer) y la infraestructura permitiendo conectar a cualquier nodo de la red independiente del lugar de cobertura, ideando autoconfiguración de ruta en todo el sistema de red, brindando ancho de bandas considerables. Ventajas: La tecnología de redes inalámbrica malladas en su implementación y rendimiento describe unas ventajas que las diferencia de otras tecnologías inalámbricas y similares, estas son: • Movilidad: Debido a sus características de integración multitopologia esta tecnología permite brindar conectividad a cualquier nodo de la red en cualquier lugar dentro del área de cobertura. • Simplicidad y rapidez en la instalación: Gracias a sus componentes tecnológicos los equipamientos de la tecnología inalámbrica mallada permiten una sencilla instalación. Por su configuración centralizada hace que cualquier persona pueda configurara y administrar este sistema. • Escalabilidad: Permite ser integrada entre red alambica, gracias a sus dispositivos. Permite la asociación de nuevos usuarios y la cobertura entre ello

First principles determination of some static and dynamic properties of the liquid 3d transition metals near melting

Producción CientíficaWe report an ab initio molecular dynamics simulation study of several static and dynamic properties of the liquid 3d transition metals. The calculated static structure factors show qualitative agreement with the available experimental data, and its second peak displays an asymmetric shape which suggests a signi1cant local icosahedral short-range order. The dynamical structure reveals propagating density 2uctuations whose dispersión relation has been evaluated; moreover, its long wavelength limit is compatible with their respective experimental sound velocity. Results are reported for the longitudinal and transverse current spectral functions as well as for the respective dispersion relations. We also analyze the possible appearance of transverse-like low-energy excitations in the calculated dynamic structure factors. Several transport coeWcients have been evaluated and compared with the available experimental data.Junta de Castilla y León (Ref. project VA124G18)Ministerio de Economía, Industria y Competitividad (Project PGC2018-093745-B-I00) and FEDE

Transfer of innovation - using research tools for engineering education

In this article, the authors show how, in the pursuit of research results, they can obtain excellent tools and data for engineering education. In particular, they describe one example of computer architecture in the Computer Engineering Degree Programme at the University of Cádiz in Spain. This research topic is of particular importance as it influences the execution of a range of the computer’s I/O operations, due to operations of peripherals and information devices, and determines processor performance. The simulator used in research and teaching in several engineering degree programmes at the University of Cádiz is also demonstrated in this article
