Injecting disinformation into public space: pseudo-media and reality-altering narratives
2022
This paper analyses the context of disinformation in Spain from the perspective of the pseudo-media (i.e., websites that mimic conventional media to offer partisan content based on alternative facts). Using a quantitative (N = 1,143) and qualitative (n = 396) methodology, this research analyses publications from eight Spanish pseudo-media that reach more than 4 million unique users. Results reveal an interest in three topics: vaccination, restrictions and speculation about Covid-19, national politics –focused on criticism against government– and topics related to human rights –mainly LGBTI, gender, immigration– with a total of 58.1% of the content published in four sections (International, …
Posverdad, o la narración del procés catalán desde el exterior: BBC, DW y RT
2019
Con el procés independentista de Cataluña como marco, compararemos el tratamiento periodístico que recibe el fenómeno en tres medios de comunicación extranjeros, reflejado en su difusión a través de la red social Facebook. BBC, DW y RT son corporaciones financiadas públicamente por gobiernos ajenos a priori a la problemática social y política generada sobre el debate separatista. Aun así, uno de ellos, RT, ha sido acusado públicamente de actuar directamente bajo la influencia de las directrices de política exterior del Kremlin, y de cometer injerencias a favor de los independentistas. Desde una perspectiva cuantitativa y cualitativa, analizamos los posts difundidos por estos medios durante …
Trato del Telediario público español a temas y líderes políticos (2014-2021)
2021
Ante la ausencia o retraso e incompletitud de registros de lo emitido en TV pública, se ofrece un estudio único, por su alcance (desde 2014 a 2021) y su novedoso método, sobre el Telediario de La 1 de Televisión Española. Se usa la herramienta Verba de la Fundación Civio, cuyo afán por la transparencia es presentado en la introducción, además de tratar la influencia de los medios en partidos políticos y agenda. El objetivo principal es evaluar dos tipos de elementos: 30 nombres de líderes políticos y 30 expresiones con incidencia política (los 15 principales problemas citados por la ciudadanía en el último CIS y otros 15 vinculados). El modelo se centra en las palabras pronunciadas y faltar…
Value creation in mobile tourism services : evaluating the value creation concerns of the Norwegian MOVE project
2007
Sammendrag på norsk og engelsk. The report presents the results of the evaluation activity specified as part of the MOVE project, a three year innovation project funded by the Research Council of Norway and seven industry and university partners. The aim of this project has been to establish a location-based electronic marketplace, offering mobile tourism services. Several pilot services including a map-based interface providing tourist guide functionality to the mobile handset, a web based tool for service providers’ registration of points of interest (POI), and two “infotainment” services (picture puzzle and riddle) has been developed. The Lofoten area was chosen as the target region for …
Simulazione della propagazione di difetti a fatica mediante il modello di zona coesiva
2009
Le giunzioni incollate guadagnano sempre più mercato, nel campo delle costruzioni in genere, dove è necessario un alleggerimento delle strutture. Nel caso di geometrie di giunto semplici il dimensionamento avviene attraverso relazioni analitiche che restituiscono il valore massimo delle tensioni, il quale deve essere inferiore al limite di utilizzo dell’adesivo stesso. Quando le geometrie sono complesse l’approccio analitico diventa impraticabile, di conseguenza si provvede a verificare la correttezza della soluzione mediante analisi agli elementi finiti (EF). L’introduzione del modello di zona coesiva nell'analisi EF permette di simulare il danneggiamento ed il cedimento del giunto in cond…

Importance sampling type estimators based on approximate marginal Markov chain Monte Carlo
2020
We consider importance sampling (IS) type weighted estimators based on Markov chain Monte Carlo (MCMC) targeting an approximate marginal of the target distribution. In the context of Bayesian latent variable models, the MCMC typically operates on the hyperparameters, and the subsequent weighting may be based on IS or sequential Monte Carlo (SMC), but allows for multilevel techniques as well. The IS approach provides a natural alternative to delayed acceptance (DA) pseudo-marginal/particle MCMC, and has many advantages over DA, including a straightforward parallelisation and additional flexibility in MCMC implementation. We detail minimal conditions which ensure strong consistency of the sug…
Yliopistotutkintojen määrän ennustaminen Bayes-mallilla
2017
Tämän tutkielman tarkoituksena on kehittää prediktiivinen malli, jolla ennustetaan Jyväskylän yliopiston matemaattis-luonnontieteellisessä tiedekunnassa lähivuosina suoritettavien luonnontieteiden kandidaatin ja filosofian maisterin tutkintojen lukumääriä. Mallin estimointiin käytettävä aineisto koostuu kolmesta osasta: vuosina 1996–2004 tiedekunnassa aloittaneet opiskelijat, vuosina 2005–2015 tiedekunnassa alemmasta korkeakoulututkinnosta aloittaneet opiskelijat ja vuosina 2005–2016 tiedekunnassa ylemmästä korkeakoulututkinnosta aloittaneet opiskelijat. Jokaiselle aineiston osalle sovitetaan omat toisistaan riippumattomat osamallit. Tutkintoennusteet saadaan ennustamalla aineistoon kuuluvi…

The role of water in the photocatalytic degradation of acetonitrile and toluene in gas-solid and liquid-solid regimes
2006
Photocatalytic degradation of acetonitrile and toluene was carried out both in gas-solid and in liquid-solid regimes by using commercialTiO2samples (Merck and Degussa P25). The investigation was mainly aimed to study the influence of water present in the reaction environment on the mechanism and degradation rate of two probe molecules. In gas-solid regime, the reacting mixture consisted of toluene or acetonitrile, oxygen, nitrogen, and water vapour. The main degradation product of toluene wasCO2with small amounts of benzaldehyde. In the presence of water vapour, the activity ofTiO2Merck remained stable but greatly decreased if water was absent.TiO2Degussa P25 continuously deactivated, even …
