It also points to a need for studying science communication at an organisational level to understand how science communication activities can be collectively organised to have a substantial impact. Despite these changes, there are ongoing questions regarding the perceived value of science communication and the ways in which it can receive institutional support in credit-driven academic cultures. Therefore, this study set out to explore how incentives relate to researchers’ communication activity and how these can be influenced by digital communication contexts. This article presents a qualitative analysis of semi-structured interviews with 17 researchers and 15 communication professionals in Finland. Results indicate that academic leaders are in the key position to support organisational science communication culture, and their acknowledgement for science communication can be more effective than encouragement from in-house communication staff. This suggests that there may be a key gap vis-à-vis training in science communication and engagement which is targeted towards scientific and organisational leaders. The results also imply there is enduring value in communication activities featuring in periodical performance evaluation and that analytic data from digital media endeavours can form an intrinsic reward.","PeriodicalId":38434,"journal":{"name":"Studies in Communication Sciences","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90535206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Anwendungsbeispiel ist die Corona-Thematisierung (September 2019 bis Dezember 2020) und ihr Einfluss auf die Thema-tisierungsprozesse von «Klima» und «Geflüchtete». Anhand einer multivariat dynamischen Zeitreihenanalyse von 437 784 Onlineartikeln wird als übergeordnete Hypothese untersucht, ob Themenverdrän-gung festgestellt werden kann. Die Mechanismen der Verdrängung werden dann differenziert als phasenabhängige Aufmerksamkeits-verschiebung und als direkte also zeitgleiche Themenverdrängung untersucht. Die Ergebnisse bestätigen die Annahme der Themen-konkurrenz und zeigen je nach Thematisierungsphase unterschiedliche Verdrängungsprozesse. Im Trend hat Corona die Thematisierung der beiden anderen Krisenphänomene zwar nicht komplett verdrängt, aber sehr deutlich reduziert. Bezüglich der direkten Verdrängung sind Effekte messbar, aber eher klein. Als Fazit zeigt sich Themenverdrän-gung im Onlinejournalismus hier also eher als Effekt der Fokusver-schiebung öffentlicher Aufmerksamkeit als ein Problem direkter Ver-drängung aufgrund beschränkten Berichterstattungsraums.\u0000In the following, classical hypotheses on the dramatization tendency of media crisis reporting and the assumed simultaneous suppression of other socially relevant topics are put to the test. For this case study, we rely on news reporting during the first year of the COVID19 pandemic (September 2019 to December 2020) to evaluate its influence on the thematization processes of «climate» and «refu-gees.» Based on a multivariate dynamic time series analysis of 437 784 online articles, we first confirm whether overall issue displace-ment can be detected and then delve deeper by differentiating into two possible mechanisms of displacement: 1) as a phase-dependent but global shift in attention and 2) as a direct i.e., simultaneous effect pointing toward editorial competition. Results from our analysis con-firm the overarching hypothesis of topic competition, clearly showing displacement processes depending on the thematization phase. Globally, while not being rendered invisible, media attention for the other two crisis phenomena was reduced significantly following the onset of the pandemic. Regarding direct displacement, effects are measurable, but rather small. We conclude that the displacement of media attention seems to be attributable more to a shift in public attention and overall trends than to classic assumptions based on limited resources in the editorial process.","PeriodicalId":38434,"journal":{"name":"Studies in Communication Sciences","volume":"81 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73710277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we apply a figurational framework to understand what roles SMCs can take in science communication. Building on ethnographic material gathered during January and October 2020, we analyze through which practices, communicative relations, mission and normative assumptions SMC Germany has shaped its position in science communication during the COVID-19 pandemic. Doing so, we follow the “cultural turn” in science communication research. Building on the concept of brokerage, we conclude that SMC Germany has taken on roles as a knowledge broker by providing journalists with curated scientific content, a trust broker by facilitating relationships between journalists and scientists, and a value broker by promoting the status of scientific expertise in the social knowledge order.","PeriodicalId":38434,"journal":{"name":"Studies in Communication Sciences","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90535564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ziel des Ansatzes ist es, die Herstellung von Öffentlichkeit in digitalen Medienumgebungen als geteilte Herstellungsleistung heterogener Akteur:innengruppen nachzuvollziehen und dabei gruppenspezifisch performativ-dramaturgische Stilmerkmale herauszuarbeiten. Zugrunde liegt ein praxeologischer Zugang, der für eine relationale Journalismus-forschung «beyond the newsroom» weiterentwickelt wird. Die Kontingenz, Vielstimmigkeit und Unübersichtlichkeit digitaler Öffentlichkeiten macht es notwendig, die traditionell mikrosoziologischen Vorgehensweisen in diesem Bereich zu verbinden mit quantitativen Netzwerkanalysen und standardisierten Akteur:innen- und Praxisanalysen. Hierfür wird ein dreistufiger Ansatz vorgestellt, der schrittweise durch quantitative und qualitative Methoden die Erstellung von «Praxisprofilen» einzelner Akteur:innen wie auch -gruppen erlaubt. Mit diesem interdisziplinären wie methodisch innovativen Ansatz soll Wandel in Öffentlichkeiten und im Journalismus auch komparativ verstehbar werden. Exemplarisch zeigen wir anhand erster Befunde zum Hashtag #systemrelevant, wie eine solche Analyse aufgebaut ist.\u0000This paper develops and presents a mixed-methods approach as a contribution to relational journalism studies. The approach aims to retrace the making of publics in digital media environments through the performative contributions of heterogeneous groups of actors and to elaborate group-specific stylistic features of their communication. It is based on a praxeological approach that is further developed for relational journalism studies “beyond the newsroom.” The contin- gency, polyphony and complexity of digital publics makes it necessary to combine traditional micro-sociological approaches in this field with quantitative network analyses and standardized analyses of actors and their practices. For this purpose, a three-stage approach is presented, which allows for the sequential development of “practice profiles” for individual actors as well as groups of actors through mixed quantitative and qualitative methods. With this interdisciplinary and methodologically innovative approach, the change of public spheres and journalism can be understood comparatively. Using the hashtag #systemrelevant as an example, we show how such an analysis is structured.","PeriodicalId":38434,"journal":{"name":"Studies in Communication Sciences","volume":"410 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84878320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Die daraus resultierende zunehmende Vielfalt politischer Positionen stellt Medien, die es sich zur Aufgabe gemacht haben, den Bürger:innen Orientierung zu geben, vor die Herausforderung, diese vielfältiger werdenden Positionen adäquat wiederzugeben. Der Beitrag untersucht am Beispiel von Deutschland, Österreich und der Schweiz, wie sich einerseits Parteien in den Parlamenten selbst darstellen und wie ihre Positionen in den nationalen Medien wiedergegeben werden. Die Positionen der Parteien werden über Value-Frames erfasst, die drei zentrale Grundkonflikte (Cleavages) westlicher Gesellschaften widerspiegeln. Es zeigt sich, dass die Parteien unterschiedliche Kombinationen von Positionen zu diesen Grundkonflikten vertreten. Insbesondere der globalisierungs-bezogene Grundkonflikt ist deutlich polarisiert, zwischen rechtspopu-listischen Parteien auf der einen Seite, konservativen Parteien im gemässigten Bereich und den linken bzw. linksliberalen Parteien am anderen Pol des Konflikts. Medien geben die Positionierungen der Parteien überwiegend ähnlich zu deren Selbstdarstellungen im Parlament wieder. Die rechtspopulistischen Parteien werden in den Medien jedoch polarisierter dargestellt, als die Parteien sich selbst positionieren. Somit erfüllen die Medien ihre Orientierungsfunktion nicht im gesamten Parteienspektrum gleich.\u0000Many Western countries have seen a pluralization and polarization of the political landscape in recent years. The resulting increase in diversity of political positions poses challenges to media that aim at providing citizens with orientation. Using Germany, Austria, and Switzerland as examples, the article analyzes how parties present themselves in the respective national parliament and how domestic media relay these utterances. The parties’ positions are examined via value frames that reflect three central cleavages of Western societies. The results show that parties express different combinations of posi-tions on these cleavages. Especially the cleavage related to globali-zation is clearly polarized, with right-wing populist parties at one end, conservative parties in a moderate place, and left-liberal parties at the other pole of the cleavage. Media reflect the parties’ positions mostly similarly to their own utterances in parliament. However, the right-wing populist parties are depicted in an even more polarized way compared to how they position themselves. The media thus fulfill their orientation function to different degrees across the party spectrum.","PeriodicalId":38434,"journal":{"name":"Studies in Communication Sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79799121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Within two different studies, we analyzed the production processes in both high budget and low budget settings. In this paper, we contrast the findings of both studies with the goal of abstracting indicators of change and implications for future productions. Based on the abstraction, we suggest changing the focus in multimedia storytelling productions from a product-oriented process toward a more process-oriented production; from a focus on hard production factors such as numbers and personnel to more soft factors such as distributed responsibilities and internal workflows; and from a focus of rather incidental communication toward a more managed communication within the production team. We conclude by deriving further implications for future research as well as journalistic practice and education.","PeriodicalId":38434,"journal":{"name":"Studies in Communication Sciences","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90824182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From an empirical point of view, diary methods, and particularly qualitative (media) diaries, bear a great potential to gain access to these media practices and analyze them within the contexts of people’s everyday lives. In this article, we propose that it is fruitful to apply the characteristics of real diaries to research settings and consider them when designing diary studies as a researcher. Doing so can help to collect more “genuine” data and get a more holistic and adequate picture of digital media life. These characteristics comprise: (1) authenticity and naturalness, (2) autonomy in design, (3) multimodality and materiality, (4) intrinsic motivation, (5) functionalities of diary keeping, (6) continuity and periodicity, as well as (7) inferences about cultural and social conditions. We provide suggestions for implementing these characteristics in qualitative diary studies, and discuss the empirical challenges accompanying this approach.","PeriodicalId":38434,"journal":{"name":"Studies in Communication Sciences","volume":"194 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72403171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By integrating sponsored content from advertisers into their feeds, they create awareness and favorable attitudes for products and brands. The effectiveness of this sponsored content builds on close adaptation to the original content of the specific media platform. To ensure transparency, influencers are required to disclose sponsored content. While effects of such disclosure labels and disclaimers have been widely examined, less attention has been paid to context factors that may influence these effects, such as placement prominence. Building on the propositions of the Persuasion Knowledge Model (PKM), this study aims to investigate the role of placement prominence as a moderator of disclosure effects. Results of an experimental study revealed that prominent placements support disclosure labels in reducing perceived deceptiveness of sponsored content, which positively affects influencer credibility and recipients’ attitudes toward the promoted brand. In contrast, disclosure effects on perceived persuasive intent vanished, when placement prominence was high. The results emphasize the importance of context factors in the processing of sponsored content and disclosures in a constantly changing social media environments.","PeriodicalId":38434,"journal":{"name":"Studies in Communication Sciences","volume":"92 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83795633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Second, as corporate social responsibility (CSR) ads are discussed to be received controversial among viewers, we explore how a social ad communi-cating a CSR message (gay rights) compared to a “classic” product ad performs on brand-relevant outcomes.

Dieser Protest war und ist Gegenstand unterschiedlicher visueller Repräsentationen und medialer Formen, die einen wichtigen Anteil an den Bedeutungsproduktionen rund um die Protesthandlungen haben. Auf Basis einer Bildtypenanalyse der (Bild-)Berichterstattung über die Proteste in deutschsprachigen Tageszeitungen sowie der Darstellungsformen auf Instagram im Kontext von Demonstrationen im deutschsprachigen Raum setzt sich der Beitrag mit visuellen Konstruktionen von Protest auseinander und diskutiert deren Bedeutung vor dem Hintergrund gesellschaftlicher, medialer und politischer Kontexte. Es zeigen sich jeweils unterschiedlich dominierende Bildtypen: So sind in der Medienberichterstattung Bilder von Demonstrierenden als Masse vorherrschend, die die einzelnen Teilnehmer:innen nicht wahrnehmbar machen. Auf Instagram finden sich vor allem Innen-Perspektiven der Demonstrationen durch individuelle (Selbst-)Inszenierungen der Demonstrierenden. Deutlich wird zudem, dass die journalistischen Bilder die Proteste insbesondere im Hinblick auf spannungsreiche Konfliktsituationen im US-Kontext mit hohem Nachrichtenwert zeigen, während auf Instagram die Vergemeinschaftung über Gruppenbilder und damit die Inszenierung und Mobilisierung der Teilnehmenden in den Vordergrund rückt.\u0000The violent death of George Floyd at the end of May 2020 triggered a global protest movement: Starting in the US, numerous rallies, demonstrations, and vigils took place around the world, taking a stand against racism and police violence. This protest was and is subject to different visual representations and mediated expressions, which have an important share in the production of meaning around the protest actions. Based on a picture type analysis of the (image) coverage of the protests in Austrian, German and Swiss newspapers as well as on visual expressions on Instagram in the context of demonstrations in German-speaking cities, the article deals with visual constructions of protest and discusses their meaning against the background of social, media, and political contexts. Different dominant image types emerge in each case: In media coverage, for example, images of demonstrators as a mass are predominant, which make the individual participants imperceptible. On Instagram, there are mainly internal perspectives of the demonstrations through individual self-dramatizations of the demonstrators. It also becomes clear that journalistic images show protests with a high news value, especially with regard to tense conflict situations in the US context, while on Instagram the communalization via group images and thus the staging and mobilization of the participants comes to the fore.","PeriodicalId":38434,"journal":{"name":"Studies in Communication Sciences","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75385176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
