A Twitter campaign against pseudoscience: The sceptical discourse on complementary therapies in Spain
2019
The main objective of this article is to analyse the sceptical movement’s discourse on complementary therapies in Spain, as well as comprehend its mobilisation against these therapies. Over the past 2 years, the Spanish sceptical movement, constituted by citizen’s associations against unconventional therapies and in favour of evidence-based medicine, has increased its activism which, as a result, is now more familiar to the public. To perform this study, three sources of information were selected: (a) the #StopPseudociencias campaign, with a corpus of 6252 tweets; (b) 153 news articles published during the study timeline and (c) 7 interviews with members of the sceptical movement, journalis…
Seek and you shall find? A content analysis on the diversity of five search engines’ results on political queries
2020
Search engines are important political news sources and should thus provide users with diverse political information ��� an important precondition of a well-informed citizenry. The search engines��� algorithmic content selection strongly influences the diversity of the content received by the users ��� particularly since most users highly trust search engines and often click on only the first result. A widespread concern is that users are not informed diversely by search engines, but how far this concern applies has hardly been investigated. Our study is the first to investigate content diversity provided by five search engines on ten current political issues in Germany. The findings show t…
How perceived persuasive intent and reactance contribute to third-person perceptions: evidence from two experiments
2016
In two experiments, this study presents a process model that explains third-person perceptions (TPP) as a function of perceived persuasive intent and reactance. Using two nonstudent samples, findings were internally replicated for two topics. The study shows that media messages evoking perceptions of persuasive intent also activate reactance, which in turn predicts TPP topic-independently. Remarkably, half of the total stimulus effect on TPP could be explained through reactance, which offers new implications for existing theoretical explanations of strong TPP after undesirable messages but weak effects after, for example, prosocial messages.
Spin doctoring in British and German election campaigns: How the press is being confronted with a new quality of political PR
2000
The 1997 British and 1998 German general elections showed striking parallels and distinctive differences in the way Blair and Schroeder delivered their campaigns and defeated long-sitting conservative governments. Of vital importance was a new quality of political public relations called `spin doctoring'. In this, the British Labour Party served as a kind of role model for the German Social Democratic Party. This article traces the origins and different meanings of `spin doctoring' in both countries, distinguishes between media-related and non-media-related spin activities and analyses it against the background of the specific national contexts. The aims and methods of political spin doctor…
Audiovisual Representation in Spanish and European Election Debates
2020
The presence of ever more conflicting stances between Europhiles and Eurosceptics has revealed some audiovisual discourses unknown until now. The fragmentation of inconclusive narrative discourse and staged situations with a clear intent to clash all make it necessary to analyse in detail the role given by the audiovisual media to the European process of democratisation. This study addresses the audiovisual discourse in Spanish public television (TVE) with the intention of discovering how the different topics addressed in debates are dealt with in audiovisual production, and whether those topics have benefited from certain decisions by the production team that are subjective a priori. Using…
Reducing the Bias: How Perspective Taking Affects First- and Third-Person Perceptions of Media Influence
2017
Third- and first-person perceptions (TPPs/FPPs) are considered to be biased judgments of media influence on self and others. Research suggests that perspective taking, i.e., thinking from another person’s position, decreases perceptual gaps between self and others via assimilation. In a two-factorial experiment (n = 431), we test whether this effect of perspective taking (Factor 1) holds true for the presumed influence of desirable and undesirable messages (Factor 2). Results indicate that perspective taking significantly reduces TPPs in the case of an undesirable message but not FPPs that are provoked by the desirable message. The observable effect traces back to a change in presumed messa…
Too Much or Too Little Messaging? Situational Determinants of Guilt About Mobile Messaging
2021
Abstract Mobile messaging has been associated with guilt. Guilt about too much messaging may result from self-control failures during goal conflicts. Conversely, guilt about too little messaging may result from violating the salient norm to be available. This research considers both boundary conditions of guilt about mobile communication—goal conflicts and availability norm salience—simultaneously for the first time. We conducted two preregistered experiments to investigate their interplay. Results from a vignette experiment, but not from a laboratory experiment, support the hypotheses that goal conflicts trigger guilt about using messengers and that guilt about not using messengers arises …
Slacking with the Bot: Programmable Social Bot in Virtual Team Interaction
2021
Nonhuman communicators are challenging the prevailing conceptualizations of technology-mediated team communication. Slackbot is a social bot that can be configured to respond to trigger words and, thus, take part in discussions on the platform. A set of 84 bot-related communication episodes were identified from a journalistic team's Slack messages (N=45,940) and analyzed utilizing both qualitative content analysis and interaction process analysis (IPA). This integrated mixed-methods analysis revealed novel insights into the micro-level dynamics of human-machine communication in organizational teams. In response to Slackbot's greetings, acclamations, work-related messages, and relational mes…
Performance analysis of underlay two-way relay cooperation in cognitive radio networks with energy harvesting
2018
Abstract Cognitive radio and energy harvesting are two important approaches to solve the problem of spectrum scarcity and energy constraint in wireless communications. In this work, we study a two-way relay cooperation scheme in underlay cognitive radio networks (CRNs) with energy harvesting in which two secondary users exchange information via an energy harvesting relay node. Since the relay node collects energy from the received signals and utilizes it to forward the information, the secondary transmission power can be markedly reduced. Therefore the interference of the secondary network to the primary network can be substantially reduced. We derive the outage probability of the secondary…
On optimal deployment of low power nodes for high frequency next generation wireless systems
2018
Recent development of wireless communication systems and standards is characterized by constant increase of allocated spectrum resources. Since lower frequency ranges cannot provide sufficient amount of bandwidth, new bands are allocated at higher frequencies, for which operators resort to deploy more base stations to ensure the same coverage and to utilize more efficiently higher frequencies spectrum. Striving for deployment flexibility, mobile operators can consider deploying low power nodes that could be either small cells connected via the wired backhaul or relays that utilize the same spectrum and the wireless access technology. However, even though low power nodes provide a greater fl…
