The news gap in the «triple digital agenda»: The different interests of media, audience and networks

Digital transformations entail continually reviewing the various Communication models and processes. The influence of the media themselves as agenda setters for an ever more active audience and social networks that select and make certain content they receive viral are also affected by such a convergent context. This current research analyses a model called here the ‘triple agenda’ within the media themselves, in which the journalistic criterion of relevance and their audience’s preferences in the web and the networks travel along different paths. The proposal includes the users and the viral effect as influencing agents in the shape and selection of news, generating a news gap of interests between the media and their audiences. In order to test this model, we study an exploratory case in ElPaís.es, applying a content analysis to the information (n=420) distributed among the online front page, what is most read by the audience in its webpage, and the most viral in its Twitter account. The main objective is to check whether or not these three spheres of relevance operate independently, showing different informative interests f rom the thematic selection that the medium establishes f rom its agenda, its audience and its social networks. The results confirm that there is a gap in the informative interests of the three spheres analysed, especially between the agenda marked by the medium and the interests that are reflected in their web audience, which is more attracted to soft news and the clickbait technique; while there is a greater coincidence of interests between the newspaper’s front page and the users’ selection in their social networks.Las transformaciones digitales conllevan una revisión permanente de los modelos y procesos de la Comunicación. En este contexto convergente también se ve afectada la propia influencia de los medios como fijadores de la agenda frente a una audiencia cada vez más activa y unas redes sociales que seleccionan y viralizan el contenido que les llega. La presente investigación analiza un modelo denominado aquí de ‘triple agenda’ dentro de los propios medios, en los que discurren de manera diferente el criterio periodístico de relevancia y las preferencias de su audiencia en la web y las redes. La propuesta incluye a los usuarios y el efecto de la viralidad como actores influyentes en la conformación y selección noticiosa, generando una brecha, o news gap, de intereses informativos entre el medio y su audiencia. Para poner a prueba este modelo, se recurre a un estudio de caso exploratorio en ElPaís.es, aplicando un análisis de contenido de sus informaciones (n=420), distribuidas entre la portada online, lo más leído por la audiencia en su web y lo más viralizado en su Twitter. El objetivo principal es comprobar si estas tres esferas de relevancia temática operan, o no, de forma independiente, mostrando intereses informativos dispares entre la selección temática que establece el medio desde su agenda, de su audiencia y de las redes. Los resultados confirman una brecha en el interés informativo de las tres esferas analizadas, especialmente entre la agenda que marca el medio y los intereses que reflejan su audiencia web, más atraída por las soft news y las técnicas del clickbait, mientras que existe una mayor coincidencia de intereses entre la portada periodística y la selección de los usuarios en sus redes sociales

Los efectos de la primera fase del EEES en la enseñanza del periodismo en España: mayor especialización y formación práctica

Este artículo ofrece un estudio comparativo de los programas de Licenciatura y Grado de 35 universidades españolas con titulación de Periodismo mediante un análisis de contenido cuantitativo y cualitativo de 66 planes de estudio con el objetivo de conocer los efectos de la primera fase del Espacio Europeo de Educación Superior (EEES) y su adaptación al nuevo entorno mediático. La investigación ofrece resultados desde cuatro perspectivas concretas: el mapa de la oferta actual de la enseñanza del Grado en Periodismo, el cambio de contenido en los planes de estudio, la continuidad o renovación general de los programas y el perfil formativo para los nuevos medios. La principal conclusión es que existe un cambio progresivo de tendencia formativa de los periodistas en España con un aumento de la enseñanza práctica-especializada y un recorte del contenido teórico-multidisciplinar. Al mismo tiempo, la investigación evidencia una limitada incorporación de asignaturas obligatorias de nuevas tecnologías para la formación en nuevos perfiles profesionales

Multimedia news storytelling: semiotic-narratological foundations

Research about multimedia news storytelling contains several empirical studies, but these lack a theoretical foundation. This article proposes a transdisciplinary foundation of multimedia news storytelling, based on semiotics and narratology. First, the bases of multimedia news storytelling are explained using a hypothetical-deductive methodology and the semiotic categories of ideation-composition-reception. Second, based on narratology, the multimedia storytelling process is described, starting from the pre-compositive stage, in which journalists assemble the stories, to the final stage of navigation by the participatory users. The combination of both theoretical foundations allows us to explain the nature of multimedia news storytelling, based on three elements: 1) syntactic coherence between the multiple languages used, 2) open and collective authorship, and 3) participatory reception by the audience

Narrativa periodística multimedia: fundamentos semiótico-narratológicos

La investigación en torno a la narrativa periodística multimedia cuenta con algunos estudios empíricos, pero adolece todavía de una débil fundamentación teórica. El presente artículo propone una fundamentación transdisciplinar de la narrativa periodística multimedia, a partir de la Semiótica y de la Narratología. Mediante un método hipotético-deductivo se explican, en primer lugar, las bases del relato multimedia desde un modelo semiótico, basado en las categorías de ideación-composición-recepción. En segundo lugar, empleando la teoría narratológica, se describe el proceso narrativo multimedia desde la fase pre-compositiva, en la que los periodistas ensamblan los relatos, hasta la fase final de navegación por parte de los usuarios participativos. La combinación de ambos fundamentos teóricos permite dar cuenta de la naturaleza del relato periodístico multimedia, sobre la base de tres elementos: 1) coherencia sintáctica en el multilenguaje, 2) autoría abierta y colectiva, y 3) recepción participativa por parte de la audiencia.Research about multimedia news storytelling contains several empirical studies, but these lack a theoretical foundation.

The nuclear and extended infrared emission of the Seyfert galaxy NGC 2992 and the interacting system Arp 245

We present subarcsecond resolution infrared (IR) imaging and mid-IR (MIR) spectroscopic observations of the Seyfert 1.9 galaxy NGC 2992, obtained with the Gemini North Telescope and the Gran Telescopio CANARIAS (GTC). The N-band image reveals faint extended emission out to ∼3 kpc, and the polycyclic aromatic hydrocarbon features detected in the GTC/CanariCam 7.5–13 μm spectrum indicate that the bulk of this extended emission is dust heated by star formation. We also report arcsecond resolution MIR and far-IR imaging of the interacting system Arp 245, taken with the Spitzer Space Telescope and the Herschel Space Observatory. Using these data, we obtain nuclear fluxes using different methods and find that we can only recover the nuclear fluxes obtained from the subarcsecond data at 20–25 μm, where the active galactic nuclei (AGN) emission dominates. We fitted the nuclear IR spectral energy distribution of NGC 2992, including the GTC/CanariCam nuclear spectrum (∼50 pc), with clumpy torus models. We then used the best-fitting torus model to decompose the Spitzer/IRS 5–30 μm spectrum (∼630 pc) in AGN and starburst components, using different starburst templates. We find that, whereas at shorter MIR wavelengths the starburst component dominates (64 per cent at 6 μm), the AGN component reaches 90 per cent at 20 μm. We finally obtained dust masses, temperatures and star formation rates for the different components of the Arp 245 system and find similar values for NGC 2992 and NGC 2993. These measurements are within those reported for other interacting systems in the first stages of the interaction.IGB acknowledges financial support from the Instituto de Astrofísica de Canarias through Fundacion La Caixa.

Mg–1Zn–1Ca alloy for biomedical applications. Influence of the secondary phases on the mechanical and corrosion behaviour

An as-cast Mg–1Zn–1Ca alloy has been soundly characterized to be used as a biodegradable material in biomedical applications. Ca and Zn additions have a great influence in the microstructure, mechanical properties and corrosion behaviour of Mg alloys. SEM examinations revealed that most of the Ca and Zn atoms form Mg2Ca and Ca2Mg6Zn3 precipitates, which distribute preferentially along the grain boundaries forming a continuous network of secondary phases. The results of nanoindentation tests show differences in hardness and elastic modulus between the α-Mg matrix and the secondary phases. The results of three-point bending tests shows that cracks propagate following the network formed by the intermetallic compounds at the grain boundaries (GBs). The evolved hydrogen after immersion in Hank’s solution of the alloy has been also estimated, showing a change in the corrosion mechanism after 160 h. The intermetallic compounds act as a barrier against corrosion, so that it progresses through the α-Mg matrix phase

Description of the exposure of the most-followed spanish instamom's children to social medias

There is evidence of the risk of overexposure of children on social networks by parents working as influencers. A cross-sectional study of the profiles of the sixteen most-followed Instamoms in Spain was carried out. An analysis of these profiles was performed over a full month (April 2022), three times a week, to describe the representation of influencers’ children in the posts shared by them, as well as their role in the Instamoms’ marketing. A total of 192 evaluations of the profiles were performed in the study period. The average number of children exposed by an Instamom was three, generally preschoolers and schoolchildren. The children appear in a context of the family home and accompanied by their mother. The type of advertising that accompanies the appearance of underage children is usually women or children’s clothing, but also food products, leisure, etc. Appearance of children in the posts had a statistically significant influence on followers measured by the number of likes. Results provided the identification of two Instamom clusters with differentiated behaviors in relation to appearance of children in posts. It is important to involve Social Pediatrics in the protection of the privacy and interests of children given the increase in sharenting. The authors believe that there are concerns about their explicit consent to public exposure from early childhood and about the medium and long-term effect that this may have on their future well-being

Evaluation of mammographic density patterns: reproducibility and concordance among scales

<p>Abstract</p> <p>Background</p> <p>Increased mammographic breast density is a moderate risk factor for breast cancer. Different scales have been proposed for classifying mammographic density. This study sought to assess intra-rater agreement for the most widely used scales (Wolfe, Tabár, BI-RADS and Boyd) and compare them in terms of classifying mammograms as high- or low-density.</p> <p>Methods</p> <p>The study covered 3572 mammograms drawn from women included in the DDM-Spain study, carried-out in seven Spanish Autonomous Regions. Each mammogram was read by an expert radiologist and classified using the Wolfe, Tabár, BI-RADS and Boyd scales. In addition, 375 mammograms randomly selected were read a second time to estimate intra-rater agreement for each scale using the kappa statistic. Owing to the ordinal nature of the scales, weighted kappa was computed. The entire set of mammograms (3572) was used to calculate agreement among the different scales in classifying high/low-density patterns, with the kappa statistic being computed on a pair-wise basis. High density was defined as follows: percentage of dense tissue greater than 50% for the Boyd, "heterogeneously dense and extremely dense" categories for the BI-RADS, categories P2 and DY for the Wolfe, and categories IV and V for the Tabár scales.</p> <p>Results</p> <p>There was good agreement between the first and second reading, with weighted kappa values of 0.84 for Wolfe, 0.71 for Tabár, 0.90 for BI-RADS, and 0.92 for Boyd scale. Furthermore, there was substantial agreement among the different scales in classifying high- versus low-density patterns. Agreement was almost perfect between the quantitative scales, Boyd and BI-RADS, and good for those based on the observed pattern, i.e., Tabár and Wolfe (kappa 0.81). Agreement was lower when comparing a pattern-based (Wolfe or Tabár) versus a quantitative-based (BI-RADS or Boyd) scale. Moreover, the Wolfe and Tabár scales classified more mammograms in the high-risk group, 46.61 and 37.32% respectively, while this percentage was lower for the quantitative scales (21.89% for BI-RADS and 21.86% for Boyd).</p> <p>Conclusions</p> <p>Visual scales of mammographic density show a high reproducibility when appropriate training is provided. Their ability to distinguish between high and low risk render them useful for routine use by breast cancer screening programs. Quantitative-based scales are more specific than pattern-based scales in classifying populations in the high-risk group.</p

A multiproxy study distinguishes environmental change from diagenetic alteration in the recent sedimentary record of the inner Cadiz Bay (SW Spain)

In this study, we reconstruct the recent environmental evolution of the inner Cadiz Bay using sedimentary records reaching back as far as AD 1700. We report lithological descriptions of the sediments and extensive mineralogical and geochemical analyses. An extraction technique that identifies different Fe phases provides an assessment of diagenetic alteration, which allows an estimation of the original organic matter inputs to the inner Cadiz Bay. Downcore variations in Corg/N ratios, δ13Corg and δ15N are related to changes in organic matter sources and the trophic state of the water column. The downcore records of selected trace metals (e.g. Pb, Zn and Cu) are interpreted to reflect changes in heavy metal pollution in the bay, while records of other elements (e.g. Mn and P) are likely overprinted by diagenetic alteration. Major environmental shifts took place during the 20th century, when the population around Cadiz Bay increased exponentially. Increases in sediment accumulation rates, organic matter inputs and heavy metal contents, in parallel with increases in δ13Corg and δ15N over this period, are interpreted as direct effects of the increasing anthropogenic influence in the area. The results of this study suggest that multiproxy approaches and detailed consideration of diagenetic overprinting are required to reconstruct past environmental conditions from coastal sediments
