This study aims to elucidate the dynamics of social media discourse during global health events, specifically investigating how users across different platforms perceive, react to and engage with information concerning such crises.

A mixed-method approach was employed, combining both quantitative and qualitative data collection. Initially, thematic analysis was applied to a data set of social media posts across four major platforms over a 12-month period. This was followed by sentiment analysis to discern the predominant emotions embedded within these communications. Statistical tools were used to validate findings, ensuring robustness in the results.

The results showcased discernible thematic and emotional disparities across platforms. While some platforms leaned toward factual information dissemination, others were rife with user sentiments, anecdotes and personal experiences. Overall, a global sense of concern was evident, but the ways in which this concern manifested varied significantly between platforms.

The primary limitation is the potential non-representativeness of the sample, as only four major social media platforms were considered. Future studies might expand the scope to include emerging platforms or non-English language platforms. Additionally, the rapidly evolving nature of social media discourse implies that findings might be time-bound, necessitating periodic follow-up studies.

Understanding the nature of discourse on various platforms can guide health organizations, policymakers and communicators in tailoring their messages. Recognizing where factual information is required, versus where sentiment and personal stories resonate, can enhance the efficacy of public health communication strategies.

The study underscores the societal reliance on social media for information during crises. Recognizing the different ways in which communities engage with, and are influenced by, platform-specific discourse can help in fostering a more informed and empathetic society, better equipped to handle global challenges.

This research is among the first to offer a comprehensive, cross-platform analysis of social media discourse during a global health event. By comparing user engagement across platforms, it provides unique insights into the multifaceted nature of public sentiment and information dissemination during crises.

This paper aims to investigate how the Japanese media conveyed the country’s foreign aid policy and analyse how framing biases in the news differ depending on which language (either Japanese or English) was used in the broadcasts.

This study uses a qualitative single case-study design and conducts a content analysis. The study uses news videos about the fifth Tokyo International Conference on African Development aired on YouTube by the Japanese media using Japanese and English.

The findings reveal subtle but notable differences in the patterns of the framing biases in the Japanese media’s news aired in Japanese intended for the domestic audience, and in the news on the same topic broadcast in English to the international audience.

The limitation of the study is the rather small data set used for the single case study of one event.

Framing biases could lead the general public in a monolingual society to a more skewed view of their government’s policy and its activities abroad. This could be an obstacle to developing a common ground for global issues and cross-border policy agendas.

The study explores an under-researched function of language in international affairs. It highlights how the mass media in a non-English-speaking country uses a dual approach to framing news while addressing different audiences. To the best of the author’s knowledge, the context that this paper deals with is novel because there are limited studies on the nexus between the influence of language choices and media logic in the field of international business.

The concept of environmental diplomacy appears associated with events (conventions) promoted between states and transnational organisations to discuss aspects related to regulating the use of natural resources and regulating pollution. In this study, the authors intend to highlight the contribution brought to environmental diplomacy by leading television figure David Attenborough and his focus on the destruction of biodiversity by humans (the problem). It is intended to analyse the frames of his public interventions, comparing them with the prevailing frames in the UNFCCC policies.

A predominantly inductive method of qualitative and interpretative nature is used. In epistemological terms, the framing analysis stems from a social constructivist perspective. A theoretical model for frame analysis was defined by combining the frameworks proposed by Entman (1993) and Semetko and Valkenburg (2000) and considering previous studies (Anholt, 2015; Seelig, 2019). Analysis scrutinised a two-fold corpus comprising articles regarding actions and statements by David Attenborough published in The Guardian between 2018 and 2020, and the UN's legal framework for climate change.

The most prominent frames regarding climate crisis in transnational policies are responsibilities. Attenborough's calls for action highlight the frames of “morality”, “responsibilities” and “problems”. However, it is necessary to make a distinction between the discourse used in transnational treaties and that by Attenborough. In the former, discourse is more technical and impersonal, presented in a structure of legal diplomas and barely accessible to the public. In contrast, Attenborough's speech is more emotional, appealing and sometimes dramatic. His message is transmitted straightforwardly to the public in a pedagogical, personal tone.

The choice of high-profile personalities like David Attenborough as ambassadors has implications in the visibility of the environmental cause, and in the multiplication of initiatives that denounce environmental degradation.

This study explores and analyses the narrative construct regarding climate change as carried out by a trusted and respected media voice. The authors intend to contribute to understanding the amplification role of public figures in controversial issues and diplomatic matters. The main contribution of this study is to highlight the strategic nature of the choice of SDA by political powers to voice the drama of climate emergency.

This study investigates the communication behavior of public health organizations on Twitter during the COVID-19 vaccination campaign in Brazil. It contributes to the understanding of the organizational framing of health communication by showcasing several instances of framing devices that borrow from (Brazilian) internet culture. The investigation of this case extends the knowledge by providing a rich description of the organizational framing of health communication to combat misinformation in a politically charged environment.

The authors collected a Twitter dataset of 77,527 tweets and analyzed a purposeful subsample of 536 tweets that contained information provided by Brazilian public health organizations about COVID-19 vaccination campaigns. The data analysis was carried out quantitatively and qualitatively by combining social media analytics techniques and frame analysis.

The analysis showed that Brazilian health organizations used several framing devices that have been identified by previous literature such as hashtags, links, emojis or images. However, the analysis also unearthed hitherto unknown visual framing devices for misinformation prevention and debunking that borrow from internet culture such as “infographics,” “pop culture references” and “internet-native symbolism.”

First, the identification of framing devices relating to internet culture add to our understanding of the so far little addressed framing of misinformation combat messages. The case of Brazilian health organizations provides a novel perspective to knowledge by offering a notion of internet-native symbols (e.g. humor, memes) and popular culture references for misinformation combat, including misinformation prevention. Second, this study introduces a frontier of political contextualization to misinformation research that does not relate to the partisanship of the spreaders but that relates to the political dilemmas of public organizations with a commitment to provide accurate information to citizens.

The findings inform decision-makers and public health organizations about framing devices that are tailored to internet-native audiences and can guide strategies to carry out information campaigns in misinformation-laden social media environments.

The findings of this case study expose the often-overlooked cultural peculiarities of framing information campaigns on social media. The report of this study from a country in the Global South helps to contrast several assumptions and strategies that are prevalent in (health) discourses in Western societies and scholarship.

This study uncovers unconventional and barely addressed framing devices of health organizations operating in Brazil, which provides a novel perspective to the body of research on misinformation. It contributes to existing knowledge about frame analysis and broadens the understanding of frame devices borrowing from internet culture. It is a call for a frontier in misinformation research that deals with internet culture as part of organizational strategies for successful misinformation combat.

This study, a narrative literature review, aims to examine the combined benefits of the active and passive use of social media (SM) for well-being (WB), physical and mental health during the COVID-19 pandemic.

A search strategy has been carried out in the databases: Riss, PubMed, Medline, Scopus and Google Scholar, including all the articles published until 19 October 2023.

SM offers various benefits, including global risk awareness, health information, social connections and support. With the natural increase in physical inactivity due to COVID-19 social restrictions, SM has been identified as an appropriate tool for promoting physical activity (PA) at home to improve health.

It suggests that the combined use of active and passive benefits of SM could potentially play an important role in public health by increasing individuals’ health behaviours. In addition, dissemination, sharing and social interaction of information provided by YouTube can encourage healthy behaviours, contribute to WB, physical and mental health and raise public health awareness.

The findings presented in this study highlight the combined benefits of differentiating the features of SM use. Compared to other SM platforms, YouTube can be used as a useful tool for home-based PA that promotes health by enabling people to remain active and avoid barriers to PA due to social restrictions during the global crisis. In addition, some recommendations from the findings may help protect against potential risks and improve public health outcomes during global crises, such as the COVID-19 pandemic, among the general public using SM.

In recent years, there has been a growth in research aimed at understanding the foundations of modern activist communication in media-rich and multi-platform environments. For example, Chon and Park's analysis of the American Black Lives Matter (BLM) movement built on Kim and Grunig's STOPS model. Yet, social and political injustice can exist for extended periods of time without successful movements emerging, so what leads people to demand social and political change through activism? This paper posits that crisis is trigger that motivates people to activism and evaluates that within the context of the Scottish independence movement.

The study is based on in-depth interviews with 26 advocates for Scottish independence, which yielded more than 32 h of data. Data were analysed using Strauss and Corbin's (1990) constant comparative method approach using open coding, axial coding and selective coding finding thematic saturation after only 10 interviews.

The study provides a clear extension of Chon and Park's model of activism by finding that crises are critical triggers for activism. Moreover, these findings also provide insights into not only the Scottish independence movement but more broadly the extension of traditional public relations and communication theory in multi-platform and multi-actor environments.

There are several contributions this piece makes. First, this paper extends activist, crisis and strategic communication research to more systematically consider the role that crisis plays in social and political advocacy. Second, this paper affords the opportunity to consider the challenges of communication, democracy and activism in the social media age. Finally, this paper supports an international view that discrimination and affective injustice experiences cut across many different kinds of identities and experiences instead of the traditionally considered ethnic, religious and gender-based experiences traditionally addressed.

This study provides real-world evidence for the relationship between strategic communication from a global/multinational perspective and the effectiveness of corporate message strategies in the context of environment risk communication. Among sustainability issues, particulate matter (PM) air pollution has threatened the health and social wellbeing of citizens in many countries. The purpose of this paper is to apply the message framing and attribution theories in the context of sustainability communication to determine the effects of risk message characteristics on publics’ risk responses.

Using a 2 (message frame: gain vs loss) × 2 (attribution type: internal vs external) × 2 (country: China vs South Korea) between-subjects experimental design, the study examines the message framing strategies' on publics' risk responses (i.e. risk perception, risk responsibility attribution held toward another country and sustainable behavioral intention for risk prevention).

Findings include (1) main effects of message characteristics on participants’ risk responses; (2) the impact of country difference on participants’ differential risk responses and (3) three-way interactions on how risk message framing, risk threats type and country difference jointly affect not only participants’ risk perception and risk responsibility attribution but also their sustainable behavioral intention to prevent PM.

Although this study used young–adult samples in China and South Korea, the study advances the theory building in strategic environmental risk communication by emphasizing a global/multinational perspective in investigating differences among at-risk publics threatened by large-scale environmental risks.

The study's findings provide evidence-based implications such as how government agencies can enhance the environmental risk message strategy so that it induces more desired risk communication outcomes among at-risk publics. Insights from our study offer practical recommendations on which message feature is relatively more impactful in increasing intention for prosocial behavioral changes.

This study on all measured risk responses reveals important differences between at-risk young publics in China and South Korea and how they respond differently to a shared environmental risk such as PM. The study's findings provide new evidence that media coverage of global environmental issues needs to be studied at the national level, and cross-cultural comparisons are imperative to understand publics’ responses to different news strategies. Thus, this study offers implications for practitioners to understand and apply appropriate strategies to publics in a social way across different countries so as to tailor risk communication messaging.

This study offers new insights to help connect message framing effects with communication management practice at the multi-national level, providing recommendations for government communication practitioners regarding which PM message features are more likely to be effective in forming proper risk perception and motivate sustainable actions among at-risk publics in different countries.
