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…

Infrastructures and Productivity in the Spanish Regions

1996

The aim of this paper is to analyse the role of public capital, the types of infrastructures in which it is invested, and their territorial distribution in the gains in productivity of the private sector in the Spanish regions in the period 1964-1991 using panel data techniques to control for unobserved state-specific characteristics. The results obtained show how the infrastructures most directly linked to the productive process present a significant and positive effect on productivity. They also show the importance of the network effect of the infrastructures of a productive nature as well as a decrease in the elasticity associated with such infrastructures as development progresses.

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…

Medidas durante el COVID-19 y Derecho mercantil (Parte II: Derecho concursal).

2020

The crisis generated by the COVID-19 pandemic has forced it to take multiple measures of different kinds to mitigate its effects during the Alarm State. These measures include those that have effects on various commercial law institutions, such as those relating to insolvency issues.

Modelos historiográficos de las primeras universidades

2015

El artículo estudia los modelos espontáneos de las universidades surgidas a inicios de la baja Edad Media en París y Bolonia, modelos que se esparcieron en otros puntos por emigraciones de grupos de escolares y por iniciativa de los pontífices, obispos y monarcas. Durante la Edad Moderna se transformaron aquellas universidades hacia estructuras más jerárquicas y se fundaron otros muchos estudios generales en las ciudades de Europa y América. Su objetivo es mostrar que, con sus distintas variantes, el análisis de los distintos modelos permite comparar, resumir y ordenar las estructuras jurídicas que organizan la vida universitaria, dando cuenta del funcionamiento y articulación de los divers…

Operation and first results of the NEXT-DEMO prototype using a silicon photomultiplier tracking array

2013

NEXT-DEMO is a high-pressure xenon gas TPC which acts as a technological test-bed and demonstrator for the NEXT-100 neutrinoless double beta decay experiment. In its current configuration the apparatus fully implements the NEXT-100 design concept. This is an asymmetric TPC, with an energy plane made of photomultipliers and a tracking plane made of silicon photomultipliers (SiPM) coated with TPB. The detector in this new configuration has been used to reconstruct the characteristic signature of electrons in dense gas, demonstrating the ability to identify the MIP and "blob" regions. Moreover, the SiPM tracking plane allows for the definition of a large fiducial region in which an excellent e…

Description and commissioning of NEXT-MM prototype: first results from operation in a Xenon-Trimethylamine gas mixture

2014

[EN] A technical description of NEXT-MM and its commissioning and first performance is reported. Having an active volume of ∼35 cm drift × 28 cm diameter, it constitutes the largest Micromegas-read TPC operated in Xenon ever constructed, made by a sectorial arrangement of the 4 largest single wafers manufactured with the Microbulk technique to date. It is equipped with a suitably pixelized readout and with a sufficiently large sensitive volume (∼23 l) so as to contain long (∼20 cm) electron tracks. First results obtained at 1 bar for Xenon and Trymethylamine (Xe-(2%)TMA) mixture are presented. The TPC can accurately reconstruct extended background tracks. An encouraging fu…

MOF-Mediated Synthesis of Supported Fe-Doped Pd Nanoparticles under Mild Conditions for Magnetically Recoverable Catalysis**

2020

Metal–organic framework (MOF)-driven synthesis is considered as a promising alternative for the development of new catalytic materials with well-designed active sites. This synthetic approach is used here to gradually transform a new bimetallic MOF, with Pd and Fe as the metal components, by the in situ generation of aniline under mild conditions. This methodology results in a compositionally homogeneous nanocomposite formed by Fe-doped Pd nanoparticles that, in turn, are supported on iron oxide-doped carbon. The nanocomposite has been fully characterized by several techniques such as IR and Raman spectroscopy, TEM, XPS, and XAS. The performance of this nanocomposite as an heterogeneous cat…
