Assessing supply chain risks in the automotive industry through a modified MCDM-based FMECA
2020
Supply chains are complex networks that receive assiduous attention in the literature. Like any complex network, a supply chain is subject to a wide variety of risks that can result in significant economic losses and negative impacts in terms of image and prestige for companies. In circumstances of aggressive competition among companies, effective management of supply chain risks (SCRs) is crucial, and is currently a very active field of research. Failure Mode, Effects and Criticality Analysis (FMECA) has been recently extended to SCR identification and prioritization, aiming at reducing potential losses caused by lack of risk control. This article has a twofold objective. First, SCR assess…
Ionization and scintillation response of high-pressure xenon gas to alpha particles
2013
High-pressure xenon gas is an attractive detection medium for a variety of applications in fundamental and applied physics. In this paper we study the ionization and scintillation detection properties of xenon gas at 10 bar pressure. For this purpose, we use a source of alpha particles in the NEXT-DEMO time projection chamber, the large scale prototype of the NEXT-100 neutrinoless double beta decay experiment, in three different drift electric field configurations. We measure the ionization electron drift velocity and longitudinal diffusion, and compare our results to expectations based on available electron scattering cross sections on pure xenon. In addition, two types of measurements add…
Consumer Demand for Environmental, Social, and Ethical Information in Fishery and Aquaculture Product Labels
2022
[EN] Customers' attention to sustainability labels in fishery and aquaculture products (FAPs) has been increasing in the last decades, and the industry has adapted to this growing interest by adopting fish ecolabels. However, there is a growing interest to widen the sustainability concept to include the social and ethical information of the fishery and aquaculture industry and to go further from the voluntary approach on the labeling of these aspects in FAPs. For this reason, using data from 2021 Eurobarometer and using machine learning techniques, we disentangle the characteristics of the FAP buyers that consider the importance of environmental impact, ethical, and social information appea…
La Empresa Familiar Multigeneracional
2009
The general aim of this work, “From the Founder to Multigenerational Family Business: The Family’s Crucial Role as an Owner for Longevity”, is to contribute in discovering the reasons why family businesses manage to survive. The conceptual approach taken as the starting point for this work, the information examined and the research methodology pursued by the authors involve criteria that are clearly different from those followed by the works from other scholars on the same topic. The conceptual approach taken here springs from the conviction that the basic key to understanding the success of a multigenerational family business lies in the qualities of the people who form the ownership group…

Triblock SEBS/DVB crosslinked and sulfonated membranes: Fuel cell performance and conductivity
2021
[EN] A set of styrene-ethylene-butylene-styrene triblock copolymer (SEBS) membranes with 10 or 25 wt.% divinyl-benzene (DVB) as a crosslinking agent were prepared and validated. Physicochemical characterization revealed suitable hydrolytic and thermal stability of photo-crosslinked membranes containing 25%wt. DVB and post-sulfonated. These compositions were evaluated in H2/O2 single cells, and electrical and proton conductivities were furtherly assessed. The membranes with the milder post-sulfonation showed greater proton conductivity than those with excessive sulfonation. In terms of electrical conductivity, a universal power law was applied, and the values obtained were low enough for bei…
Efectos de las tareas de elaboración de resúmenes en el control de la comprensión de textos científicos en estudiantes universitarios con niveles de …
2012
Two studies were conducted to improve Spanish university student's comprehension monitoring of macro-ideas when reading expository Science texts in English (L2). The first one evaluated the effects of using summarization tasks on comprehension monitoring compared to other reading-for-understanding tasks. A significant improvement of comprehension monitoring was obtained from the summarization tasks. Results in study 1 suggested study 2 aimed at instructing students on summarizing texts in L2. The instructional work had a single significant contribution to students’ comprehension monitoring on the macro-structural level. English proficiency also explained a significant proportion of the vari…
La toma inteligente de decisiones en los procesos de planificación de destinos turísticos de litoral: el plan de infraestructuras turísticas de canar…
2017
El Plan de Infraestructuras Turísticas de Canarias [PITCAN2017-2013] es un encargo de la Dirección General de Infraestructuras Turísticas de la Consejería de Turismo, Cultura y Deportes del Gobierno de Canarias a un grupo de investigadores de la Cátedra de Turismo CajaCanarias‐Ashotel‐Universidad de La Laguna y del grupo de investigación de la ULL ReinvenTUR: renovación e innovación turística, a través de la Fundación General de la Universidad de La Laguna. El objetivo del plan es enumerar y priorizar las infraestructuras turísticas públicas a implementar en el período 2017-2023. Para el desarrollo de este objetivo se ha aplicado un proceso metodológico basado en la participación de agentes…
Edificios de viajeros del Trenet 1920. De Francisco Mora a Calatrava
2003
La actual infraestructura del ferrocarril de vía estrecha en la provincia de Valencia es el resultado de una emblemática red de comunicaciones de casi 120 años de antigüedad. Red que se ha proyectado, construido, modificado, derribado o conservado durante un largo periodo cronológico, donde las tendencias y necesidades de un determinado momento histórico marcan las diferentes tipologías de los edificios de viajeros. El objetivo principal de este artículo es presentar los proyectos arquitectónicos de los edificios de viajeros desde 1920 hasta la actualidad; desde Francisco Mora con la ruptura del modelo clasicista y funcional de los primeros tiempos del ferrocarril hasta las estaciones tecno…
