ABSTRACT
Lu and Jin provide insights into public health crisis communication (PHCC) by reconceptualizing how we think about the concept of dosage. The chapter extends the notion of dosage from the amount of exposure to publics' engagement over time in a competitive and conflicting media environment. Lu and Jin delineate a new direction in PHCC by formulating the effect of crisis communication strategy and dosage according to a chemical analogy of solution concentration (i.e. strategy) and volume of solution (i.e. dosage). First, this chapter visualizes PHCC as a neutralization process, in which the base solution (i.e. PHCC strategy and dosage) to neutralize the harm caused by the acid solution (i.e. a public health crisis). Second, this chapter further analogizes the PHCC as the base solution consisting of a solute dissolved into a solvent, where the solute is the message strategy (e.g. emotional appeal) and the solvent is the carrier of the message similar to messengers and channels. Lu and Jin define the concept of PHCC dosage as the volume of "base solution,” which will influence the effectiveness of the neutralization (i.e. PHCC). This new conceptual framework, illustrated with recent public health crisis cases, helps explain PHCC (in)effectiveness. Lu and Jin also provide a theoretical foundation for empirical studies that examine and predict how both the strategy and dosage of a crisis response message might exert intended and/or unintended effects among publics confronted with information clutters and desensitized by previous and/or ongoing crisis situations. The chapter explores new possibilities for research and application of PHCC. © 2023 John Wiley & Sons Ltd.
ABSTRACT
Background: Emoticons and emojis have become staple additions to modern-day communication. These graphical icons are now embedded in daily society through the various forms of popular social media and through users' personal electronic conversations. With ever-increasing use and inclusivity, exploration of the possible health care and dermatology applications of these tools is imperative. Objective: The goal of this narrative review was to provide and evaluate an up-to-date literature survey examining the utility of emoticons and emojis in medicine. Special attention was paid to their existing and potential uses in the field of dermatology, especially during the COVID-19 pandemic. Methods: A PubMed search of peer-reviewed publications was performed in mid-2021 to collect articles with emoticon or emoji keywords in combination with other health care-relevant or dermatology-relevant keywords. Screening of publications and described studies was performed by the authors with education and research experience in health care, dermatology, social media, and electronic communication trends. Selected articles were grouped based on common subjects for qualitative analysis and presentation for in-depth discussion. Results: From this extensive search, researchers were able to identify a wide variety of publications detailing the use of emoticons and emojis in general health care, pediatric health care, public health, and dermatology. Key subject areas that emerged from the investigation included the ability of emoticons and emojis to improve communication within pediatric health care, enhance mood and psychological assessment or mental health screening in adults, develop interventions to improve patient medication adherence, complement novel means of public health and COVID-19 surveillance, and bolster dermatology-specific applications. Conclusions: This review illuminated the repurposing of emojis and emoticons for a myriad of advantageous functions in health care and public health, with applications studied in many populations and situations. Dermatology-specific uses were relatively sparse in the literature, highlighting potential opportunities for growth in future studies and practices. The importance of diversity and inclusivity has extended to emojis, with the recent introduction of skin color customization and new emojis better representing the comprehensive spectrum of users' experiences. A continuously evolving and technology-driven population creates a unique niche for emoticons and emojis to ease worldwide communication and understanding, transcending the barriers of age, language, and background. We encourage future studies and innovations to better understand and expand their utility.
