El proceso sociocultural y educativo de la televisión en la difusión del arte y el patrimonio
2005
El ente televisivo sigue siendo el paradigma de la comunicación de masas. Por ello, es necesario conocer los mecanismos y oportunidades que nos ofrecen sus emisiones para la difusión del patrimonio cultural y artístico. Partiendo de los presupuestos básicos que toda televisión pública adquiere por el hecho de serlo, el usuario debe situarse como un espectador crítico, teniendo en cuenta la labor pedagógica de la televisión, y defendiendo su capacidad como difusora de un patrimonio protegido por la legislación vigente. El consenso entre la oferta y la demanda, debe partir de un periodismo especializado, en un nuevo contexto televisivo donde los espacios temáticos se nos ofrecen dentro de un …
Estrategias de encuadre discursivo en periodismo político: análisis de un corpus de titulares
2014
En este trabajo combinamos la aplicación de conceptos de lingüística cognitiva y de teoría de la comunicación de masas para analizar un corpus de titulares de noticias de prensa escrita mediante un modelo de análisis del discurso centrado en cinco estrategias lingüísticas de encuadre: la estrategia intencional (tipo de acto de habla), léxica (usos marcados de la designación), predicativa (rentabilización de la iconicidad sintáctica en los actos expresivos), textual (uso de las superestructuras narrativa o argumentativa) e interactiva (dialogismo e intertextualidad). Se vincula el uso de estas estrategias a la mediatización periodística, que convierte el discurso de la comunicación política …
Análisis comparativo del discurso sobre Innovación Disruptiva en los medios de comunicación y la literatura académica
2020
[EN] This study aims to compare the media discourse on the disruptive innovation phenomenon with the academic literature published on that topic. For this purpose, 864 news articles referring to disruptive innovation were retrieved from the international news database Factiva. In addition, 161 academic papers including the term “disruptive innovation” were found on the Core collection of Web of Science published from 2004 until 2019. The automatic content analysis of the data will be carried out with the text-mining software Leximancer. The expected contribution of the study is related to uncovering how the media, in its role of agenda-setter and facilitator of the adoption of disruptive in…
Determinantes de la divulgación de información sobre sostenibilidad en los gobiernos locales de Latinoamérica
2022
This paper analyses the socioeconomic factors that influence the disclosure of sustainability information on 99 local government websites in 2018 in countries that make up the Pacific Alliance (PA) in Latin America, associated with internal and external demands that public entities have for accountability in social and environmental issues. We use as methodology a content analysis of the sustainability information disclosed by local entities on their websites and a regression of Ordinary Least Squares (OLS). This article shows empirical evidence that the size, budget capacity and the economic level of the municipality are factors associated with the sustainability disclosure on websites due…

Characterization of a medium size Xe/TMA TPC instrumented with microbulk Micromegas, using low-energy gamma-rays
2014
NEXT-MM is a general-purpose high pressure (10 bar, $\sim25$ l active volume) Xenon-based TPC, read out in charge mode with an 8 cm $\times$8 cm-segmented 700 cm$^2$ plane (1152 ch) of the latest microbulk-Micromegas technology. It has been recently commissioned at University of Zaragoza as part of the R&D of the NEXT $0\nu\beta\beta$ experiment, although the experiment's first stage is currently being built based on a SiPM/PMT-readout concept relying on electroluminescence. Around 2 million events were collected during the last months, stemming from the low energy $\gamma$-rays emitted by a $^{241}$Am source when interacting with the Xenon gas ($\epsilon$ = 26, 30, 59.5 keV). The localized…

NEXT-100 Technical Design Report (TDR). Executive summary
2012
[EN] In this Technical Design Report (TDR) we describe the NEXT-100 detector that will search for neutrinoless double beta decay (ßß0v) in 136XE at the Laboratorio Subterráneo de Canfranc (LSC), in Spain. The document formalizes the design presented in our Conceptual Design Report (CDR): an electroluminescence time projection chamber, with separate readout planes for calorimetry and tracking, located, respectively, behind cathode and anode. The detector is designed to hold a maximum of about 150 kg of xenon at 15 bar, or 100 kg at 10 bar. This option builds in the capability to increase the total isotope mass by 50% while keeping the operating pressure at a manageable level. The readout pla…
Initial results of NEXT-DEMO, a large-scale prototype of the NEXT-100 experiment
2013
NEXT-DEMO is a large-scale prototype of the NEXT-100 detector, an electroluminescent time projection chamber that will search for the neutrinoless double beta decay of Xe-136 using 100-150 kg of enriched xenon gas. NEXT-DEMO was built to prove the expected performance of NEXT-100, namely, energy resolution better than 1% FWHM at 2.5MeV and event topological reconstruction. In this paper we describe the prototype and its initial results. A resolution of 1.75% FWHM at 511 keV (which extrapolates to 0.8% FWHM at 2.5 MeV) was obtained at 10 bar pressure using a gamma-ray calibration source. Also, a basic study of the event topology along the longitudinal coordinate is presented, proving that it…
Radiopurity control in the NEXT-100 double beta decay experiment: procedures and initial measurements
2013
[EN] The "Neutrino Experiment with a Xenon Time-Projection Chamber" (NEXT) is intended to investigate the neutrinoless double beta decay of Xe-136, which requires a severe suppression of potential backgrounds. An extensive screening and material selection process is underway for NEXT since the control of the radiopurity levels of the materials to be used in the experimental set-up is a must for rare event searches. First measurements based on Glow Discharge Mass Spectrometry and gamma-ray spectroscopy using ultra-low background germanium detectors at the Laboratorio Subterraneo de Canfranc (Spain) are described here. Activity results for natural radioactive chains and other common radionucl…
