Building on computer-mediated interpersonal theories [i.e., attribution theory, warranting theory, and authenticity model of computermediated communication (CMC)], this study aims to explore how people interpret and reconcile perceived inconsistent expressions on social media. Through thematic analysis of data obtained from six focus groups, two main themes were extracted: the origin of perceived inconsistency on social media and the strategies for reconciling perceived inconsistency. Specifically, three forms of perceived inconsistent information were identified: those within the same account; those between public and private accounts; and those between online and offline settings. Additionally, three types of reconciliation strategies were distilled from participants' narratives: relying on authentic representation; engaging in perspective-taking to compensate for situational factors; and inferring inner motives behind acting inconsistently. With these two themes, this study proposes a two-stage model of processing inconsistency (i.e., reasoning from inconsistency to consistency) in CMC. This model suggests that several factors-including perceived authenticity, social categorical cues, and relationship or familiarity between observers and a presenter-are involved in perceiving inconsistent information and determine the outcomes of interpersonal evaluations. These findings enhance our understanding of online interpersonal perceptions.

Because information security (IS) experts with database access are the weakest link in the IS chain, scholarly contributions are needed in this important area. The interpretations of widespread data breaches committed by organizations’ information security experts have significant grounding. Drawing on social control theory, we propose a research framework to examine formal control, informal control, and self-control systems that can affect IS professionals’ perceptions and IS behaviors in Chinese IT organizations. We use in-depth interviews with IS professionals in Wuhan, Beijing, and Shenzhen to answer research questions relating to the research framework. The study’s primary contribution is to go beyond the extant IS research, which concentrates on sanction-based deterrence, and identify multiple dimensions rooted in social control perspectives. Based on interviews with practitioners and researchers, this study further advances our understanding of IS control deviance using information management and communication-related approaches.

Methods Four hundred and eighteen adults in the US participated in the study via Amazon Mechanical Turk in August 2020. Statistical analyses were performed using the PROCESS macro. Indirect effects and their significance were estimated using bias-corrected bootstrap confidence intervals (CIs) with resampling set to n = 5000. Results Perceived net equity was positively associated with low levels of perceived uncertainty regarding a COVID-19 contact-tracing application and intention to adopt it. Low levels of perceived uncertainty were positively associated with intentions to adopt such an application, thereby suggesting that a perceived level of uncertainty mediates the association between perceived net equity and adoption intentions. Anxieties regarding AI technology and COVID-19 risks both moderate the associations among perceived net equity, perceived level of uncertainty, and intentions to adopt the contact-tracing technology. Conclusions Our findings highlight how the differing sources of emotion influence the associations among rational judgment, perceptions, and decision-making about new contact-tracing technology. Overall, the results suggest that both rational judgments and affective reactions to risks are important influencers of individuals’ perceptions and privacy-related decision-making regarding a new health technology during the pandemic.

Past research examined RRP responses in real world (i.e., offline) settings, however, many companies use RRPs online. This study examines how responses to RRPs differ between these two environments. We find that recommendation behavior is driven by the givers\u2019 perception (i.e., their metaperception) of how they will be viewed by the receivers. However, metaperception has a lower impact on referral likelihood online than offline, and incentives have a less negative impact on metaperception in online environments

Previous studies on car use reduction relied on established theories related to values and self-regulation to examine this decision. In this paper, we offer an alternative approach and examine the intention to reduce car use through the prism of identity theory, and propose environmental and moral identities, together with environmental concern, as the main antecedents to the importance of car use reduction and intention to reduce car use. Further, we consider ride-sharing intention as an outcome of the decision to reduce car use. The proposed conceptual model is tested on a sample of consumers from the United Kingdom using an online consumer panel. The results offer partial support for the influence of moral identity, environmental identity, and environmental concern on the importance to reduce car use and intention. The links among the importance of and intention to reduce car use, along with ride-sharing intentions, are supported. Finally, managerial implications are discussed, and future research directions are suggested.

We examined students' attitudes toward the technology using two different approaches. First, we utilized the technology acceptance model to investigate the attitude formation process. Then, to investigate how attitudes changed over time, we applied social information processing model using social network analysis method. Using the technology acceptance model, we were able to demonstrate that students' initial expectation affected the perceptions of, attitudes toward, and use of the system. With social network analysis, we found that one's attitude change was significantly influenced by other students' attitude changes. We discussed the uniqueness of distance learning environments in the context of social influence research and how studies of distance learning could contribute to the research on the social influence of technology use.
