(2019). However, Wu & Wu (2019) argued that this indicator would be inconsistent. We propose revised disruption indices (DI* and DI#) which make the indicator theoretically more robust and consistent. Along similar lines, Chen et al. (2020) developed the indicator into two dimensions: disruption and consolidation. We elaborate the improvements in simulations and empirically. The relations between disruption, consolidation, and bibliographic coupling are further specified. Bibliographic coupling of a focal paper with its cited references generates historical continuity. A two-dimensional framework is used to conceptualize discontinuity not as a residual, but a dimension which can further be specified.","PeriodicalId":20684,"journal":{"name":"Profesional De La Informacion","volume":"14 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2021-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82296792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This scarce commodity, whose market value lies in its credibility and depends on costly investments of time and money in professional research, has frequently required a subsidy, which for more than a century was provided by advertising. Now that this subsidy has mostly been devoured by technological platforms such as Google and Facebook, the industry and profession are developing new models focused on user needs and wants with a trend toward public service rather than profit. This paper uses deductive and critical methodologies to identify the most promising business models used by media companies to counteract the decline in public-interest journalism. Our proposal is that an appropriate business model can be the best way to revitalize media companies. The research is based on Chesbrough’s business model framework applied to 20 leading digital news publications from 16 countries. In addition, we analyze how Covid-19 has impacted those business models.","PeriodicalId":20684,"journal":{"name":"Profesional De La Informacion","volume":"1 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2021-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76015605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sin embargo, en las ultimas decadas ha surgido un nuevo genero: el periodismo comic, una formula creativa que hibrida codigos y rutinas del comic con recursos narrativos propios del periodismo de inmersion. A principios de los anos noventa, Joe Sacco destaco entre una serie de autores que popularizaron este nuevo formato, tomo conciencia de la condicion del comic como genero informativo y busco una formula propia para contar historias de no ficcion. El fotografo, publicado originalmente en 2003, supuso la inclusion de fotografias para dar mayor realismo a esta formula y narrar la experiencia vivida por Didier Lefevre en la guerra de Afganistan en 1986. En 2016, los periodistas Carlos Spottorno y Guillermo Abril publican La grieta, un relato que vuelve a mezclar codigos procedentes del periodismo y del comic, donde fotografias sometidas a un tratamiento cromatico especial sustituyen a los dibujos en cada vineta. El presente estudio analiza el impacto y la evolucion del periodismo comic a traves de este diario de campo de dos reporteros que recorren una linea fronteriza que comienza en Africa y llega hasta el Artico, con el fin de desentranar las causas y consecuencias de la crisis de identidad de Europa. Una obra traducida a varios idiomas y merecedora de varios premios internacionales, que abre nuevas vias de experimentacion narrativa y estetica en el terreno del periodismo comic.

However, this greater social participation in political discourse through such platforms does not always translate into an improvement in the quality of democratic deliberation. The aim of this research is to examine the characteristics of comments and conversations on YouTube in a pre-election period to determine whether such discursive interaction contributes to strengthening the democratic system or if, on the contrary, is detrimental to it. Adopting a quantitative–qualitative approach, content analysis and critical discourse analysis are combined to examine 471 comments collected from the most viewed videos on YouTube in the month before the Andalusian elections held on 2 December 2018. Various aspects are considered, including the theme and typology of opinions, the use of foul language, and the modes that the conversation adopts. The results indicate a social discourse in which the exchange of opposing positions prevails, including comments with a strong emotional burden that tend to attack or criticize the ideology of the protagonists in the videos, and where rudeness is present (although there are exceptions), mainly as personal insults among the participants. The characteristics of the conversation taking place on this online video platform in the pre-election period do not meet the minimum standards for argumentation and civil behavior in digital political debate, thus far from contributing to an improvement in the quality of deliberative processes, it is deteriorated.","PeriodicalId":20684,"journal":{"name":"Profesional De La Informacion","volume":"41 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2021-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89360618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

El gran aumento de contenido ofrecido al usuario (que reduce la concentracion de espectadores a una seleccion limitada), su explotacion dentro del modelo economico de la suscripcion (que elimina la cotizacion publicitaria del espacio) y la multiplicacion de consumos en distintos horarios y a traves de distintos recepto-res, muchos de ellos moviles y fuera del hogar (lo que complica su monitorizacion), ha generado un nuevo ecosistema. Dentro del mismo, el exito ya no se puede evaluar en base a los indicadores de la audimetria tradicional. En el presente articulo se aborda como se comporta la audiencia en el consumo de contenidos en plataformas de streamingy las nue-vas dimensiones con las que se evalua el exito de una serie televisiva mas alla de los datos que ofrecen las tecnicas de medicion de audiencias (TAM). Se repasa la transformacion del concepto de popularidad y el impacto en el medio que distribuye el contenido de estos nuevos indicadores de audiencia, que anaden a los elementos tradicionales (anuncian-tes y ventas internacionales) nuevas dimensiones (engagement, retencion de clientes, captacion de talento, nuevas altas, branding, etc.). El estudio se integra en un marco de investigacion mas amplio que avanza en la construccion de un nuevo concepto de audiencia en el consumo de video bajo demanda en modelo de suscripcion (tomando Netflix como referencia, dada su cuota de mercado) y reflexiona sobre si es posible un concepto de audiencia unico aplicable a todos los modelos de consumo y explotacion audiovisual bajo demanda.

Exponential growth in the content available to users (which reduces viewer concentration based on a limited selection), its commercialisation through a subscription-based business model (removing advertising from content) and the boom in consumption on different receivers, many of them mobile or outside the home (thus complicating people meter monitoring), has generated a new ecosystem where success can no longer be assessed using traditional audience measurement systems.
