Análisis de las plataformas de crowdfunding social en el estado español: un estudio de casos
2018
Las actuales tecnologías de la información y comunicación han propiciado un incremento en la capacidad de agrupación virtual de la sociedad, a través de la generación de un nutrido y variado conjunto de espacios de colaboración y participación comunicativa. Ello ha generado un nuevo marco de oportunidades de fundraising para el Tercer Sector de acción social español, frente al progresivo deterioro experimentado en su financiación tradicional a raíz de la crisis económica. Un nuevo marco donde se encuentra una herramienta con potencial para reconfigurar cualitativamente las estructuras de fundraising de las entidades sociales, dando cabida a una democratización financiera desde su propia bas…
Violent Conflict and Online Segregation: An Analysis of Social Network Communication Across Ukraine's Regions
2016
Does the intensity of a social conflict affect political division? Traditionally, social cleavages are seen as the underlying cause of political conflicts. It is clear, however, that a violent conflict itself can shape partisan, social, and national identities. In this paper, we ask whether social conflicts unite or divide the society by studying the effects of Ukraine's military conflict with Russia on online social ties between Ukrainian provinces (oblasts). In order to do that, we collected original data on the cross-regional structure of politically relevant online communication among users of VKontakte social networking site. We analyze the panel of provinces spanning the most active p…
La productividad científica sobre MOOC: aproximación bibliométrica 2012-2016 a través de SCOPUS
2017
Los Massive Online Open Courses (MOOC) han supuesto un hito en la educacion online en los ultimos cinco anos. La proliferacion de cursos y plataformas para su difusion han hecho que el fenomeno no solo sea un punto de reflexion educativa, social y politica, sino que tambien pase a la esfera academica como objeto de investigacion. El presente estudio analiza la productividad cientifica del fenomeno MOOC a partir del analisis de 752 publicaciones indexadas en la base de datos SCOPUS en el periodo 2012-2016. Los datos extraidos permiten realizar una radiografia global del estado del fenomeno, la evolucion que ha sufrido en los ultimos anos, el tipo de publicaciones que sustentan el fenomeno, l…
Resonancia cultural y consonancia informativa como elementos favorecedores de la simbiosis discursiva entre activismo y periodismo en protestas educa…
2020
El movimiento neocon que impulsó la protesta contra Educación para la Ciudadanía se reactivó con el anuncio del Ejecutivo de Pedro Sánchez de introducir una nueva asignatura de valores cívicos y éticos en el currículo escolar. Esta investigación analiza los mensajes difundidos por las principales organizaciones conservadoras para determinar el protagonismo que este tema tuvo en su producción comunicativa y si responden a un marco de acción colectiva. Además, se contrasta dicho discurso con el que plantearon las mismas entidades entre 2004-2008 y se estudia su reproducción en la prensa ideológicamente afín. Se analizan los mensajes de estos grupos en Twitter (n = 131) y en sus webs (n = 11) …
Insights from a Simulation Model of Disaster Response: Generalization and Action Points
2016
In a prior paper we presented a system dynamics model that simulates responder behavior in a Norwegian landslide. The model shows how a set of vicious feedback loops caused by following standard organizational procedures that do not fit the disaster situation initially increases errors in response. Eventually learning and sensemaking in an improvisation/experimentation process leads to new emergent dynamics whereby the loops act virtuously. In this paper we aim to generalize this initial study by explaining in more detail how the model can describe large scale disaster responses of different types and how it relates to the wider disaster response literature. We discuss what types of levers,…
Antecedents and consequences of problematic smartphone use: A systematic literature review of an emerging research area
2021
Abstract This article provides a systematic review of existing research on problematic smartphone use (PSU) to guide other researchers in search of relevant studies, and to propose areas for future research. In total, 293 studies were analyzed leading to the development of an overview model in the field of PSU, presenting findings on demographic factors, explanations for smartphone use and why this use becomes problematic, consequences of PSU, and how such use can be corrected. In addition, we considered in which contexts, with which methods, and with which theoretical lenses this stream of research has been studied to date. Smartphone use is most often explained by the smartphone design, a…
Reciprocal Effects: Toward a Theory of Mass Media Effects on Decision Makers
2007
The article presents a framework for the analysis of reciprocal effects of mass media—in this case, their impact on subjects of media reports, especially on decision makers in areas of politics and business. It outlines a feedback model with three sets of variables referring to (1) media coverage and media as institutions, (2) awareness and processing of information, and (3) observable effects on subjects and others.The article presents several theories that explain effects on decision makers and illustrate the relevance of this approach with empirical data from a broad range of quantitative studies. In the final section, theoretical and methodological problems of such an approach are discu…
Becoming Politically Active: Life Courses and the Formation of Capitals among Young People of Migrant Origin in Finland
2020
This article focuses on the life courses of young people of migrant origin who are active in civic and political fields in Finland. The aim is to analyse, from the micro-level life course perspective, the issues in their lives that have helped them to become active. The article draws on empirical data collected using participatory methods. Four young people of migrant origin participated in the research process and contributed to the data analysis. The theoretical framework consists of Bourdieusian concepts of political habitus and emotional, cultural and social capital. The article shows that participants gained strong emotional capital during their childhood, which laid the groundwork for…
El tiempo de uso de los videojuegos en el rendimiento académico de los adolescentes
2020
El uso de los videojuegos entre los jóvenes ha generado una gran preocupación por sus posibles efectos negativos para su salud, socialización y rendimiento académico. Respecto a este último aspecto, existen estudios que apuntan a que los videojuegos son negativos para el rendimiento académico mientras que en otras investigaciones se encuentran efectos positivos. Por esto, el presente trabajo se ocupa de las relaciones entre el tiempo de uso de videojuegos y el rendimiento académico de los escolares adolescentes de la Comunidad Valenciana. Se utilizó un cuestionario ad hoc, validado a través de juicio de expertos (0,8 validez y confiabilidad) para realizar este estudio transversal ex post fa…
Making interaction with virtual reality accessible : rendering and guiding methods for subtitles
2021
AbstractAccessibility in immersive media is a relevant research topic, still in its infancy. This article explores the appropriateness of two rendering modes (fixed-positioned and always-visible) and two guiding methods (arrows and auto-positioning) for subtitles in 360° video. All considered conditions have been implemented and integrated in an end-to-end platform (from production to consumption) for their validation and evaluation. A pilot study with end users has been conducted with the goals of determining the preferred options by users, the options that result in a higher presence, and of gathering extra valuable feedback from the end users. The obtained results reflect that, for the c…
