The impact of source credibility and risk perception attitudes on Americans' willingness to participate in contact tracing applications

Contact tracing has emerged as one tool to communicate infection risks with the public during the COVID-19 pandemic. This study uses source credibility and the risk perception attitude framework to interpret how Americans responded to contact tracing messages from a technology company, employer, physician, or state government. Survey participants (n = 245) were generally positive towards a contact tracing message regardless of source. Participants with high risk perceptions and low efficacy beliefs responded more strongly to appeals from their company and their physician while the low risk-low efficacy group found the state government appeal more compelling. The results suggest that several sources delivering the same health message could engage people with different risk perceptions and efficacy beliefs.

Impact of Electronic Word-Of-Mouth on Consumer-Based Brand Equity and Purchase Intention: Hotel Industry in Thailand

Electronic word-of-mouth is a new form of informal communication where messages are disseminated to others using social media and other electronic platforms. This research investigates eWOM to determine its impact on the perception of brand equity and the intentions of consumers to purchase hotel services in Thailand. Using a quantitative approach and a non-probability sampling method, 410 Thai respondents aged 18 and above with relevant hotel experiences participated in this study. Confirmatory Factor Analysis (CFA) and Structural Equation Modeling (SEM) were used to analyze the model fit and the validity and reliability of the variables. In addition, in order to investigate the relationship between the constructs, first-order and second-order approaches were used, in which eWOM was the second-order construct in the study, while its credibility, valence, and volume, were first-order constructs. The findings indicated that eWOM positively affects all brand equity dimensions and purchase intentions, showing the strongest significant positive effect on brand awareness. Additionally, brand equity dimensions were shown to mediate the effect of eWOM on purchase intentions. Details of the analyses and discussions are included in the latter part of this paper.

Save the Trip to the Store: Sustainable Shopping, Electronic Word of Mouth on Instagram and the Impact on Cosmetic Purchase Intentions

The COVID-19 pandemic has forced many brands to stop using cosmetic testers to avoid the risk of spreading the infection, jeopardising the future of cosmetic testing. Consequently, consumers must find alternative methods to conduct their information searches and, more importantly, the prospects of shopping online without going to the store to test the product. With the enormous prospects of social media cosmetic electronic word of mouth (eWOM), it is imperative to examine the influence of cosmetic eWOM on social media and for cosmetic marketers to understand the antecedents that result in cosmetic consumers making a purchase. The adapted information adoption model was validated through structural equation modelling based on 341 eligible surveys. The results confirmed that information quality, source credibility, information usefulness, and information adoption are the key antecedents in eWOM on Instagram when investigating purchase intentions in the colour cosmetic industry. This study is one of the pioneers in empirically testing the relationship between information quality and source credibility on information usefulness and, subsequently, the relationship between information usefulness, information adoption, and purchase intentions in a western market based on the cosmetic industry. These new insights provide practical implications for a cosmetic marketer, suggesting the key variables leading to purchase intentions in cosmetic eWOM, which can be utilised in marketing techniques.

The Impact of Communicating Advocacy and Scientific Uncertainty on a Scientist's Trustworthiness

A central aspect of scientific knowledge is scientific uncertainty. When scientists touch upon political issues, there are two contrary expectations: One is that scientists communicate in a straightforward manner and give a direct, concrete suggestion. The other is that they communicate in a way that carefully considers the pros and cons as well as the current state of (non-) knowledge. This 2x2 experimental study investigated how disclosing scientific uncertainty affects the perceived trustworthiness of a scientist when they express either their motive to inform or their motive to advocate. All participants (N = 503) read an interview with a scientist about the usefulness of further vaccinations against COVID-19. In the interview, uncertainty was explicitly addressed (vs. not). Furthermore, the scientist either disclosed their motive to advocate or their motive to merely inform about research results. Results showed that the scientist was perceived as more trustworthy (i. e., having more expertise, integrity, and benevolence) when they communicated uncertainty than when they did not. However, contrary to our expectations, the effect of the scientist's expressed motive to advocate (vs. to inform) on trustworthiness did not depend on whether uncertainty was explicitly addressed or not.

Homefluencers' endorsement of millennial consumers' purchase intention in new normal

PurposeThe purpose of this study is to examine how "homefluencers" sponsored posts on millennial consumers' purchase intention in the international marketing sphere can be impacted in the new normal by drawing on source credibility, parasocial interaction (PSI) and persuasion knowledge model (PKM) theory.Design/methodology/approachThis research applies structural equation modeling (SEM) and mediation analysis as the data analysis method using non-probability purposive sampling of a total of 217 local millennial Instagram and Facebook users, who have followed homefluencers sponsored posts in fashion-beauty, yoga-fitness and food sectors.FindingsBased on hypothesis testing, advertising recognition strongly mediates purchase intention with the indirect effects of expertise and trustworthiness than attractiveness.Research limitations/implicationsThis research extends the international marketing literature on source credibility, PSI, PKM and purchase intention theory in the new normal by proposing "Homefluencer's Endorsement Model for Purchase Intention" (HEMPI). Specifically, the mediating role of ad recognition of homefluencers sponsorship disclosure (#paidad, #sponsored), positively affects "change-of-persuasion meaning" on Instagram and Facebook, where research is rare.Practical implicationsThis research provides valuable suggestions for global brand owners, consumers and authorities of Instagram and Facebook to consider post-COVID consumer behavior highlighting homefluencers sponsored collaboration.Originality/valueThe authors have contributed to the use of the source credibility model and PSI to identify the antecedents in determining how the homefluencer's effective sponsorship disclosure can positively activate ad recognition on millennial consumers' purchase intention in a crisis period from an international standpoint with the practical implications in post-COVID.

Expert Credibility and Sentiment in Infodemiology of Hydroxychloroquine's Efficacy on Cable News Programs: Empirical Analysis.

BACKGROUND: Infodemic exacerbates public health concerns by disseminating unreliable and false scientific facts to a population. During the COVID-19 pandemic, the efficacy of hydroxychloroquine as a therapeutic solution emerged as a challenge to public health communication. Internet and social media spread information about hydroxychloroquine, whereas cable television was a vital source. To exemplify, experts discussed in cable television broadcasts about hydroxychloroquine for treating COVID-19. However, how the experts' comments influenced airtime allocation on cable television to help in public health communication, either during COVID-10 or at other times, is not understood. OBJECTIVE: This study aimed to examine how 3 factors, that is, the credibility of experts as doctors (DOCTOREXPERT), the credibility of government representatives (GOVTEXPERT), and the sentiments (SENTIMENT) expressed in discussions and comments, influence the allocation of airtime (AIRTIME) in cable television broadcasts. SENTIMENT pertains to the information credibility conveyed through the tone and language of experts' comments during cable television broadcasts, in contrast to the individual credibility of the doctor or government representatives because of the degree or affiliations. METHODS: We collected transcriptions of relevant hydroxychloroquine-related broadcasts on cable television between March 2020 and October 2020. We coded the experts as DOCTOREXPERT or GOVTEXPERT using publicly available data. To determine the sentiments expressed in the broadcasts, we used a machine learning algorithm to code them as POSITIVE, NEGATIVE, NEUTRAL, or MIXED sentiments. RESULTS: The analysis revealed a counterintuitive association between the expertise of doctors (DOCTOREXPERT) and the allocation of airtime, with doctor experts receiving less airtime (P<.001) than the nonexperts in a base model. A more nuanced interaction model suggested that government experts with a doctorate degree received even less airtime (P=.03) compared with nonexperts. Sentiments expressed during the broadcasts played a significant role in airtime allocation, particularly for their direct effects on airtime allocation, more so for NEGATIVE (P<.001), NEUTRAL (P<.001), and MIXED (P=.03) sentiments. Only government experts expressing POSITIVE sentiments during the broadcast received a more extended airtime (P<.001) than nonexperts. Furthermore, NEGATIVE sentiments in the broadcasts were associated with less airtime both for DOCTOREXPERT (P<.001) and GOVTEXPERT (P<.001). CONCLUSIONS: Source credibility plays a crucial role in infodemics by ensuring the accuracy and trustworthiness of the information communicated to audiences. However, cable television media may prioritize likeability over credibility, potentially hindering this goal. Surprisingly, the findings of our study suggest that doctors did not get good airtime on hydroxychloroquine-related discussions on cable television. In contrast, government experts as sources received more airtime on hydroxychloroquine-related discussions. Doctors presenting facts with negative sentiments may not help them gain airtime. Conversely, government experts expressing positive sentiments during broadcasts may have better airtime than nonexperts. These findings have implications on the role of source credibility in public health communications.

Optimization of urban emergency support material distribution under major public health emergencies based on improved sparrow search algorithm.

The outbreak of major public health emergencies such as the coronavirus epidemic has put forward new requirements for urban emergency management procedures. Accuracy and effective distribution model of emergency support materials, as an effective tool to inhibit the deterioration of the public health sector, have gradually become a research hotspot. The distribution of urban emergency support devices, under the secondary supply chain structure of "material transfer center-demand point," which may involve confusing demands, is studied to determine the actual situation of fuzzy requests under the impact of an epidemic outbreak. An optimization model of urban emergency support material distribution, based on Credibility theory, is first constructed. Then an improved sparrow search algorithm, ISSA, was designed by introducing Sobol sequence, Cauchy variation and bird swarm algorithm into the structure of the classical SSA. In addition, numerical validation and standard test set validation were carried out and the experimental results showed that the introduced improved strategy effectively improved the global search capability of the algorithm. Furthermore, simulation experiments are conducted, based on Shanghai, and the comparison with existing cutting-edge algorithms shows that the designed algorithm has stronger superiority and robustness. And the simulation results show that the designed algorithm can reduce vehicle cost by 4.83%, time cost by 13.80%, etc. compared to other algorithms. Finally, the impact of preference value on the distribution of emergency support materials is analyzed to help decision-makers to develop reasonable and effective distribution strategies according to the impact of major public health emergencies. The results of the study provide a practical reference for the solution of urban emergency support materials distribution problems.

Changing attire, changing impressions: How instructor attire influences undergraduate student perceptions

As time passes, different groups of students might perceive things differently than those who preceded them. The idea of what higher education should be, look like, feel like, and be reflected upon in the aftermath might be shifting from the worldviews which have existed in recent decades. Added to the generally changing nature of perspectives, students have endured a substantial paradigm shift caused by the Covid-19 pandemic which upended their anticipation of what the classroom will be like, including assessing their instructors and the content of those courses. Literature has suggested that nonverbal signals, including attire, can influence perceptions of others which further suggests that by manipulating how one dresses, they can have a strategic impact on how others perceive them. As such instructors in higher education may not be up to date with the knowledge of how students are perceiving them which in turn could affect engagement, grades, content utilization, evaluations, and enrollment, all of which have implications for the entire organizational apparatus. A quantitative methodology utilizing an experimental survey design was utilized with a convenience sample of 144 undergraduate students enrolled in Communication Studies courses at a large mid-Atlantic university to determine what styles of instructor attire influenced student perceptions of the instructor's credibility, approachability, and affective learning qualities. Data was analyzed using a one-way analysis of variance (ANOVA) via SPSS which revealed that significant differences in attire for approachability and affective learning existed between attire styles, but not for credibility. While this study was helpful in updating knowledge of student perceptions of instructor attire, it was limited to only the perspectives of a Caucasian male and only the perceived characteristics of credibility, approachability, and affective learning qualities. Future researchers may want to replicate this study for greater generalizability, explore other instructor demographics and/or to add additional perceptual attributes or characteristics.

CRISIS & EMERGENCY RISK COMMUNICATION: Six Principles for OSH Professionals

[...]as of this writing, the last complete revision to the CDC's CERC framework took place in 2014, and the last update to the web page where it is housed was in 2018 (CDC, 2018a). While OSH professionals may not find themselves as the face of a response effort, their subject matter expertise is essential to helping their organizations identify potential hazards and implement appropriate controls using effective communication (CDC, 2018b;Loon, 2020). [...]it is critical for OSH professionals to apply these six principles of CERC to remain accurate, credible and timely in their risk communication. In situations such as serious injuries and fatalities, extreme weather events, environmental or property damage, or even infectious disease outbreaks, OSH professionals are well positioned to be the source of immediate subject matter expertise even if the situation is not fully understood. [...]while establishing their position as the first to present the information relevant to their subject matter expertise, OSH professionals must accurately present what is known, what is not known and the processes in place to fill any knowledge gaps (CDC, 2018b).

Relaunching Coase's Paradox in the Age of Social Networks and Covid-19 Pandemic

Disinformation and misleading narratives have been the prominent aspects of polluting public debate during the last US presidential elections and the Covid-19 pandemic. This paper attempts to evaluate the problem of freedom of speech through the lens of Ronald Coase's paradox about the similarities between the << market for goods >> and the << market for ideas >>. After discussing the suitability of the Coasian metaphor, according to which any form of interventionism on one of these spheres will produce outcomes on the other one, it states that this clearly emerges today insomuch online platforms, such as social networks, are becoming accountable for polluting (in terms of externalities) pieces of content shared by users.

Mobile payment adoption by citizens of tier-II cities with special reference to COVID-19: extending UTAUT with intrinsic motivation and perceived credibility

The present study aims to identify the main determinants of mobile payment adoption in tier-II cities, specifically in the wake of COVID-19. We tried to contribute to the existing body of knowledge by proposing a model that combines two constructs, i.e., intrinsic motivation and perceived credibility in an extended unified theory of acceptance and use of technology (UTAUT2). The research model was empirically tested using 450 responses from a questionnaire-based survey conducted in India. Data was analysed using structural equation modelling (SEM). We found intrinsic motivation and effort expectancy as the most significant determinants of the behavioural intentions to adopt mobile payment in tier-II cities of India. COVID-19 also emerged as a factor, but not the most important factor in the study. The study has relevance for practitioners also because understanding the key constructs is crucial to design, refine, and implement mobile payment services.

Predicting College Students' Preventative Behavior During a Pandemic: The Role of the Health Belief Model, Source Credibility, and Health Literacy

In this study, we examined the effects of perceived source credibility of the Centers for Disease Control (CDC) and college student health literacy in predicting the likelihood of enacting preventative behaviors related to mitigating COVID-19. Using the Health Belief Model (HBM) as an explanatory tool, we analyzed how perceived source credibility and health literacy levels predict college students' likelihood to enact preventative behaviors during a public health crisis. Sample population entirely consisted of undergraduate students enrolled in a basic communication course at a large, southern university. The participants completed survey questionnaires about their perceived health literacy, health beliefs, trust in the CDC, perceptions of COVID-19, and demographic measures during the fall 2020 semester. A multiple regression analysis revealed that (a) HBM predictors, health literacy and CDC source credibility accounted for 44% of the variance in likelihood of enacting preventative health behaviors, and (b) health literacy, CDC source credibility, and perceived severity were all positive predictors of enacting preventative health behaviors, while (c) perceived barriers negatively predicted enactment of preventative health behaviors. Perceived susceptibility and perceived benefits were not significant predictors of college student risk mitigation. Our data suggests the importance of health literacy and source credibility in predicting college students' likelihood to enact preventative behaviors during public health crises. © 2023 SAGE Publications.

(Mis)information, sources and credibility: Targeting youth in public health response to COVID-19 in Uganda

This chapter investigates the status of urban youths' knowledge of the COVID-19 pandemic and related prevention measures;their sources of information about COVID-19 and their trust in sources of information about COVID-19;credibility of urban youths' sources of information about COVID-19;related prevention measures and the effect of the above on urban youths' attitudes towards the adoption of preventive measures against COVID-19. An online survey and three focus group interviews were conducted to collect data. Results indicated that although the majority of young people in urban Uganda were knowledgeable about COVID-19, they also held various misconceptions about it yet this presence of cognitive dissonance, did not negatively affect their adoption of preventive measures. Instead, it worked as a motivator to find more information for change. © 2022 by Angella Napakol, Elizabeth Kitego and Carol Azungi Dralega.

Communication for Coproduction: The Informational Role of Nonprofit Organizations

Governments and citizens need to coproduce a better response to the coronavirus pandemic. However, the unavailability and inaccessibility of essential information, the information asymmetry between governments and citizens, the misinformation, and the information overload all influence coproduction adversely. NPOs worldwide are making useful information available and accessible to governments and citizens, serving as information intermediaries to reduce the degree of information asymmetry, increasing information credibility to lighten the information overload, and clarifying misinformation. All these informational roles of NPOs are valuable to governments and citizens for fighting against the coronavirus and coproducing better health outcomes.

Zoomvesting: angel investors' perception of subjective cues in online pitching

PurposeThe COVID-19 pandemic transformed angel investment meetings from in-person to online. The purpose of this paper is to explore whether this move affected angel investors' perception of subjective behavioral cues in pitch sessions within a large Brazilian angel group.Design/methodology/approachThis study followed an exploratory approach using a triangulation process that combined observation, documents and interviews. Data collected by observation, document studies, and interviews were themed, coded, and organized during the research.FindingsThe move from in-person to online pitches did not seem to affect levels of trustworthiness or arrogance as angels assessed more message content during Q&A sessions. Body movement, gestures and "eye gaze” (i.e. the look on a presenter's face) played a central role in passion assessment during in-person meetings. Body language was highly limited during online sessions and tone of voice became the main source of passion assessment.Research limitations/implicationsThe findings of this study suggest that pitches at online meetings affect angel investors' perception of founders' subjective cues, particularly cues pertaining to passion. Entrepreneurs should be trained to convey passion with tone of voice and to improve their body language in the context of webcam use. The interviews with volunteer sampling were subject to volunteer bias. Additionally, the findings may be affected by cultural context.Practical implicationsA practical contribution of this study is to highlight the need for entrepreneurs to be trained for online pitches. In an online setting, body language is limited, but it is still possible to use one's hands and tone of voice to connect better to investors.Originality/valueThis study is unique because it captures the transition of angel investment meetings from in-person affairs before the pandemic to online meetings during the pandemic crisis. These unique circumstances provided a real-world laboratory to observe founders' subjective cue effects on angel investment decision-making.

When wearing a mask is (not) the norm: Political partisanship and persuasion in the context of COVID-19

This study examined the effects of source partisanship and credentials on persuasion. Democrats and Republicans (N = 206) read a policy statement advocating for a national mask mandate, ostensibly written by either a doctor or layperson, associated either with the Democratic or Republican party. Participants' perceptions of the source and receptivity to the message aligned with their political party's normative position on the issue: Democrats rated the source as more competent and trustworthy, engaged in less counterarguing, and supported the policy more than Republicans. Although the doctor was trusted more than the layperson and Republicans (but not Democrats) attributed more trust and competence to an ingroup than an outgroup source, source characteristics had no effect on message receptivity.

Data-driven analytics of COVID-19 'infodemic'.

The rampant of COVID-19 infodemic has almost been simultaneous with the outbreak of the pandemic. Many concerted efforts are made to mitigate its negative effect to information credibility and data legitimacy. Existing work mainly focuses on fact-checking algorithms or multi-class labeling models that are less aware of the intrinsic characteristics of the language. Nor is it discussed how such representations can account for the common psycho-socio-behavior of the information consumers. This work takes a data-driven analytical approach to (1) describe the prominent lexical and grammatical features of COVID-19 misinformation; (2) interpret the underlying (psycho-)linguistic triggers in terms of sentiment, power and activity based on the affective control theory; (3) study the feature indexing for anti-infodemic modeling. The results show distinct language generalization patterns of misinformation of favoring evaluative terms and multimedia devices in delivering a negative sentiment. Such appeals are effective to arouse people's sympathy toward the vulnerable community and foment their spreading behavior.

Perceptions of likability and credibility of criminal defendants appearance in court proceedings via live or video conference

The use of video conferencing in the legal system has expanded in recent years. An exponential increase was noted during the 2020 spread of the SARS-CoV-2 virus and subsequent COVID-19 pandemic. The threat of contagion led courts across the country to modify their procedures to include on-line video mediated proceedings. While this technology was previously available and in use, the pandemic caused an immediate and exclusive pivoting to virtual proceedings. To date, there are many opinions about the effect of videoconferencing in the courtroom, but they are not often data driven. The existing research had identified some differences in the experience of live versus video conferenced courtroom appearances. However, there was no available data on how video conferenced proceedings might affect viewers' opinions of a defendant and how those impressions might influence aspects of the court process. The present study sought to further understand the impact of video conferencing a defendant in the courtroom.A randomized experimental design was used to assess the effect of video-conferenced mock court appearance on participants' judgements of the defendant. Participants were each given a legal case vignette, either a case involving a misdemeanor or a case involving a felony. They then watched either a live mock court appearance or a video conferenced mock court appearance of the defendant and completed survey measures of defendant likeability and trustworthiness, whether the defendant was guilty or innocent and their confidence in their decision. Results indicated no statistically significant difference the variables of confidence, likability or trustworthiness. Additionally, no statistical significance was observed in defendants' guilt or innocence. Results of the present pilot study denote a need for further investigation and understanding of the differences in presenting a defendant as a live presence the courtroom or present via video conferencing.

Young People Under ‘Finfluencer': The Rise of Financial Influencers on Instagram: An Abstract

Under the shadow of the covid-19 pandemic, millions of young people have the resulting consequences (e.g., increased uncertainty regarding their careers and economic prospects: McGrindle, 2020;Yuesti et al., 2020) started to think more seriously about how to manage their financial resources. As a result, personal finance has become trendy to speak about. Rather than proactive actions coming through the formal financial services industry to address the increasing demand for accessible financial information that does not require an advisor or costs a fortune, we are witnessing the uprising of personal finance influencers. These financial influencers (a.k.a. Finfluencers) talk about how to manage various aspects of financial life and do so by promoting their advice on a broad scope of money related topics (ranging from dealing with student loans, buying a house, how to ask for a pay raise, budgeting tips, and tricks, filing for tax returns, stock investment opportunities, and portfolio management) in short, light-hearted video formats that are posted on Instagram, Tiktok, YouTube and other social media platforms. Although currently, these Finfluencers can be regarded as a niche influencer marketing group, it is expected to grow exponentially in the coming years – especially now that designated sections on social media platforms are taking off (e.g., #FinTok, #FinTwit, #Finmeme, #StockTok, #Findependence). In line with this trend, this research explores how consumers consume social media influencers when they offer utilitarian (rather than hedonic) oriented products, services, and advice. Using text-mining techniques, we examine the content of personal finance influencers on Instagram to investigate how consumers respond to the recommendation of more utilitarian-oriented products. In addition, gender and race are an integral part of the consumer's perception of financial expertise. This research looks at the moderating role of gender and race on influencers' financial expertise on consumer response. We found that influencers with financial accreditations generate a more positive affective response compared with financial influencers who mainly share information stemming from personal experience. In addition, we found that influencers' gender and race moderate the relationship between financial expertise and consumers' affective responses significantly. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Entertaining information: Third-party influencers' role in COVID-safety health communication

This paper discusses findings from a commissioned evaluation of an Australian government COVID-19 health campaign that utilised third-party influencers to increase the reach of health communication messages among culturally and linguistically diverse young people. Although the campaign was successful, interviews with select influencers and target audience members indicated that the ‘serious' tone of the health messaging was less effective and less likely to be shared and that messages should be more ‘entertaining'. Analyses of data indicated three themes providing insights into how future campaigns may benefit from a focus that draws together health information and entertainment using models already constructed in the entertainment–education field: (1) Entertaining health messages have a stronger fit with influencers who are known for their entertainment value;(2) Entertaining messages are more memorable and more likely to be shared;(3) A balance between entertainment and the signifiers of trust and credibility such as government health authority logos overcomes trust issues in the context of current health disinformation and misinformation. © The Author(s) 2023.
