The current study examined various types of misinformation related to the COVID-19 vaccines and their relationships to vaccine hesitancy and refusal. Study 1 asked a sample of full-time working professionals in the US (n = 505) about possible misinformation they were exposed to related to the COVID-19 vaccines. Study 2 utilized an online survey to examine U.S. college students' (n = 441) knowledge about COVID-19 vaccines, and its associations with vaccine hesitancy and behavioral intention to ge

This study examined how entry‐level employees interacted with social media during three stages of organizational socialization. They navigated between four different media affordances (persistence, editability, visibility, and association) while experiencing them as both enabling and constraining in different socialization stages. Qualitative interview data analysis revealed during anticipatory socialization, job applicants realized visibility and persistence in relation to institutional and ind

This exploratory study examines the critical factors associated with news consumers’ perception of information overload and news consumption patterns. An online survey was conducted with Qualtrics panels (N = 1001). The demographics and three antecedent factors of perceived information overload were considered including the frequency of news access through multiple media platforms, level of attention to news, and interest in news. Three news consumption patterns were investigated as possible con

Given the important implications of social support on managing volunteers and their organizational commitment, we investigated how members of a Korean immigrant church ( N = 178) exchanged two distinctive kinds of social support (i.e., informational and tangible). We used theories of centrality and homophily to hypothesize patterns of social connections among organizational members. Employing exponential random graph modeling (ERGM), the current study estimated the likelihood of age and gender h

A hierarchical regression analysis of U.S.-based Korean immigrants ' mobile communication use (i.e., voice calling and texting) and their social network characteristics (i.e., network size, diversity, and centrality) revealed significant associations between texting with coethnic strong ties and network centrality within the ethnic community. Korean immigrants who texted frequently with both coethnic and host weak ties had larger networks. Network diversity was, however, associated only with voi

A theoretical model of trust in human-machine communication (HMC) was tested and emotional experience and social presence were evaluated during an interaction with an intelligent virtual agent (IVA), Siri. A two (‘American female’ or ‘American male’ Siri) by two (functional or social task) experiment was conducted with 229 subjects with random assignments. According to multivariate analyses of covariances, participants reported higher levels of emotional significance when they interacted with Si

The current study explored a whole-network approach to measure the impact of institutional completeness at an individual-level with regards to [Kim, Y. (2001). Becoming intercultural: An integrative theory of communication and cross-cultural adaptation. Thousand Oaks, CA: Sage.] a theoretical model of cross-cultural adaptation. A new construct of ‘ethnic entrainment’ was proposed as a way to bridge the different levels of theoretical constructs in the model. The analytical challenge of verifying

The mobile phone appropriation (MPA) scale, originally developed in German, was translated into and adapted to English and initially validated through a confirmatory factory analysis (CFA) in this study. First, the theoretical background of the MPA model is briefly introduced, followed by explanations regarding the process of translating the original German scale into English (and its back-translation). English data CFA results are discussed in comparison with the CFA results from the most recen

This study investigated the impact of task types (functional vs. social) and the gendered voices (female vs. male) of Siri, an intelligent virtual assistant (IVA), on social presence and trust perceptions toward the IVA.In an online experiment involving 172 participants, individuals were randomly assigned to one of four conditions, interacting with Siri on their iPhones for various task inquiries.Results from multivariate analyses of covariances revealed significant differences in trust levels b
