Navigating high-choice European political information environments : a comparative analysis of news user profiles and political knowledge
2021
The transition from low- to high-choice media environments has had far-reaching implications for citizens’ media use and its relationship with political knowledge. However, there is still a lack of comparative research on how citizens combine the usage of different media and how that is related to political knowledge. To fill this void, we use a unique cross-national survey about the online and offline media use habits of more than 28,000 individuals in 17 European countries. Our aim is to (i) profile different types of news consumers and (ii) understand how each user profile is linked to political knowledge acquisition. Our results show that five user profiles – news minimalists, social m…
An Agenda for Open Science in Communication
2021
Contains fulltext : 226720.pdf (Publisher’s version ) (Open Access) In the last 10 years, many canonical findings in the social sciences appear unreliable. This so-called "replication crisis" has spurred calls for open science practices, which aim to increase the reproducibility, replicability, and generalizability of findings. Communication research is subject to many of the same challenges that have caused low replicability in other fields. As a result, we propose an agenda for adopting open science practices in Communication, which includes the following seven suggestions: (1) publish materials, data, and code; (2) preregister studies and submit registered reports; (3) conduct replicatio…
The Effects of Right-Wing Populist Communication on Emotions and Cognitions toward Immigrants
2018
The persuasiveness of right-wing populist communication has become a widely discussed topic; it is often assumed that such messages might foster anti-immigrant attitudes among citizens. The present study explores the effects of the different components of right-wing populist communication—anti-immigrant messages, populist content, and populist style—on attitudes toward immigrants. By combining a media content analysis ( N = 605 articles) with a panel survey ( N = 1,968) in metropolitan areas of four Western European countries (France, Germany, Switzerland, and the United Kingdom), this study analyzes how citizens’ attitudes toward immigrants are influenced by the right-wing populist commun…
The effects of populism as a social identity frame on persuasion and mobilization: evidence from a 15-country experiment
2020
This article investigates the impact of populist messages on issue agreement and readiness for action in 15 countries (N = 7,286). Specifically, populist communicators rely on persuasive strategies by which social group cues become more salient and affect people's judgment of and political engagement with political issues. This strategy is called ‘populist identity framing’ because the ordinary people as the in‐group is portrayed as being threatened by various out‐groups. By blaming political elites for societal or economic problems harming ordinary people, populist communicators engage in anti‐elitist identity framing. Another strategy is to blame immigrants for social problems – that is, …
331 models and grand unification: From minimal SU(5) to minimal SU(6)
2016
We consider the possibility of grand unification of the $\mathrm{ SU(3)_c \otimes SU(3)_L \otimes U(1)_X}$ model in an SU(6) gauge unification group. Two possibilities arise. Unlike other conventional grand unified theories, in SU(6) one can embed the $\mathrm{ SU(3)_c \otimes SU(3)_L \otimes U(1)_X}$ model as a subgroup such that different multiplets appear with different multiplicities. Such a scenario may emerge from the flux breaking of the unified group in an E(6) F-theory GUT. This provides new ways of achieving gauge coupling unification in $\mathrm{ SU(3)_c \otimes SU(3)_L \otimes U(1)_X}$ models while providing the radiative origin of neutrino masses. Alternatively, a sequential va…
What Drives Populist Styles? Analyzing Immigration and Labor Market News in 11 Countries
2019
The success of populist political actors in Western democracies and the dramatization and emotionality of political communication in news media have been the object of several theoretical and empirical studies in the past decade. It has been argued that the mediatization of politics and the convergence of populist and tabloid communication styles foster these developments by mutual promotion in mass communication. This article uses a cross-national quantitative content analysis to disentangle associations among news genres, populist actors, content, and style. In spite of indisputable prevalence of populist styles in tabloid style media, populist ideology is identified as their strongest s…
El proceso de formación de la estrategia y los tipos de trabajo desde una perspectiva microorganizativa.
2008
Partiendo de la idea de que el proceso integrador de formación de la estrategia es el más eficiente en entornos turbulentos, planteamos también que este proceso es el más eficiente en la gestión del trabajo, y en especial del trabajo complejo. El objetivo general planteado es estudiar porqué un enfoque integrador de la estrategia puede ser más eficiente en la gestión del trabajo y en especial en el trabajo complejo; y cómo, a través de qué variables, el proceso integrador de formación de la estrategia genera resultados organizativos superiores en la gestión del trabajo. Seguimos una metodología cualitativa con estudio múltiple de casos. El diseño del estudio de casos siguió la estructura de…
La gestión de recursos humanos y el desempeño laboral
2011
Las organizaciones se adaptan al entorno mediante las estrategias y políticas empresariales. La gestión de la fuerza laboral es clave a la hora de adaptarse a las demandas del entorno y esto puede llevar en muchas ocasiones al éxito o el fracaso de la empresa. La gestión de la fuerza laboral se realiza mediante el sistema de gestión de recursos humanos (RRHH). Fisher (1989) subdivide el sistema de gestión de RRHH en macro recursos humanos y micro recursos humanos. Los macro RRHH están relacionados con aspectos estratégicos (fusiones, adquisiciones, perspectivas de aumento o disminución de la fuerza laboral) y los micro RRHH incluyen la selección, formación, evaluación del desempeño, esto es…
Protein delivery based on uncoated and chitosan-coated mesoporous silicon microparticles
2011
Mesoporous silicon is a biocompatible, biodegradable material that is receiving increased attention for pharmaceutical applications due to its extensive specific surface. This feature enables to load a variety of drugs in mesoporous silicon devices by simple adsorption-based procedures. In this work, we have addressed the fabrication and characterization of two new mesoporous silicon devices prepared by electrochemistry and intended for protein delivery, namely: (i) mesoporous silicon microparticles and (ii) chitosan-coated mesoporous silicon microparticles. Both carriers were investigated for their capacity to load a therapeutic protein (insulin) and a model antigen (bovine serum albumin) …
Does the platform matter? Social media and COVID-19 conspiracy theory beliefs in 17 countries
2021
While the role of social media in the spread of conspiracy theories has received much attention, a key deficit in previous research is the lack of distinction between different types of platforms. This study places the role of social media affordances in facilitating the spread of conspiracy beliefs at the center of its enquiry. We examine the relationship between platform use and conspiracy theory beliefs related to the COVID-19 pandemic. Relying on the concept of technological affordances, we theorize that variation across key features make some platforms more fertile places for conspiracy beliefs than others. Using data from a crossnational dataset based on a two-wave online survey cond…
