The onset of the COVID-19 pandemic was accompanied with a pandemic of fake news spreading over social media (SM). Fact checking might help combat fake news and a plethora of fact-checking platforms exist, yet few people actually use them. Moreover, whether fact checking is effective in preventing citizens from falling for fake news, particularly COVID-19 related, is unclear. Against this backdrop, we examine potential antecedents to fact checking that can be a target for interventions and establish that fact checking is actually effective for preventing the public from falling for harmful COVID-19 fake news. We use a representative U.S. sample collected in April of 2020 and find that awareness of fake news and patterns of active SM use (e.g., commenting on content instead of reading it) increases the fact checking of COVID-19 fake news, whereas SM homophily reduces fact checking and the effects of SM use as users are trapped in “echo chambers”. We also find that fact checking helps users identify accurate information on how to protect themselves against COVID-19 instead of false and often harmful claims propagated on SM. These findings highlight the importance of fact checking for combating COVID-19 fake news and help identify potential interventions.

The explosive growth of mobile devices and their widespread acceptance by customers along with the potential benefits of autoID technologies have prompted retailers to consider adoption of emerging technologies. Their motives are to enhance in-store customer shopping experience and to acquire an advantage in the competitive retail environment. Two interrelated issues nevertheless have been a hindrance: mobile shopping application usability and customers’ privacy concerns. Drawing on a recently developed conceptualisation of mobile application usability and the multidimensional developmental theory of privacy, we tackle these two issues. We theorise about the impact of artifact design on mobile application usability and the consequent impact of usability on customers’ privacy concerns and shopping efficiency. We tested our hypotheses in two retail store laboratory studies in which the participants were assigned to two different shopping tasks: general browsing (n = 194) and goal-directed shopping (n = 190). We found that adhering to mobile application usability principles could mitigate privacy concerns and consequently, improve shopping efficiency. Our findings suggest new avenues to alleviate customers’ privacy concerns using artifact design, thus complementing conventional approaches that focus on preventive measures to deal with the issue of privacy concerns.

Research on information technology (IT) adoption and use, one of the most mature streams of research in the information science and information systems literature, is primarily based on the intentionality framework. Behavioral intention (BI) to use an IT is considered the sole proximal determinant of IT adoption and use. Recently, researchers have discussed the limitations of BI and argued that behavioral expectation (BE) would be a better predictor of IT use. However, without a theoretical and empirical understanding of the determinants of BE, we remain limited in our comprehension of what factors promote greater IT use in organizations. Using the unified theory of acceptance and use of technology as the theoretical framework, we develop a model that posits 2 determinants (i.e., social influence and facilitating conditions) of BE and 4 moderators (i.e., gender, age, experience, and voluntariness of use) of the relationship between BE and its determinants. We argue that the cognitions underlying the formation of BI and BE differ. We found strong support for the proposed model in a longitudinal field study of 321 users of a new IT. We offer theoretical and practical IT implications of our findings.

As most mobile applications are tailored for worldwide consumption, it is a significant challenge to develop applications that satisfy individuals with various cultural backgrounds. To address this issue, we drew on a recently developed conceptualization and associated instrument of mobile application usability to develop a model examining the impact of mobile social media application usability on continued intention to use. Drawing on Hofstede’s five cultural values, we incorporated espoused cultural values of masculinity/femininity, individualism/collectivism, power distance, uncertainty avoidance, and long-term orientation into our model as moderators. To test the model, we collected data from 1,844 consumers in four countries – the U.S., Germany, China, and India – who use mobile social media applications on their smartphones. The results provided support for the role of espoused national cultural values in moderating the impact of mobile social media application usability on continued intention to use and the model, with espoused cultural values explaining significantly more variance in continued intention to use (i.e., 38%) than the main effects-only model (i.e., 19%). Interestingly, our results demonstrated that culture at the national level did not play a significant role in affecting the relationship between usability constructs and continued intention to use, thus underscoring the importance of espoused culture.

We identified 7 theoretical models that have been used to explain technology adoption and use. We then examined the boundary conditions of these models of technology adoption when applied to the household context using longitudinal empirical data from households regarding their purchase and use decisions related to household technologies. We conducted 2 studies and collected 1,247 responses from U.S. households for the first study and 2,064 responses from U.S. households for the second study. Those households that had adopted household technologies were surveyed regarding their use behavior. Potential adopters (i.e., those who had currently not adopted) were surveyed regarding their purchase intentions. This allowed us to identify the most influential factors affecting a household's decision to adopt and use technologies. The results show that the model of adoption of technology in the household provided the richest explanation and explained best why households purchase and use technologies.

Software development is a complex undertaking that continues to present software project teams with numerous challenges. Software project teams are adopting extreme programming (XP) practices in order to overcome the challenges of software development in an increasingly dynamic environment. The ability to coordinate software developers' efforts is critical in such conditions. Expertise coordination has been identified as an important emergent process through which software project teams manage non-routine challenges in software development. However, the extent to which XP enables software project teams to coordinate expertise is unknown. Drawing on the agile development and expertise coordination literatures, we examine the role of collective ownership and coding standards as processes and practices that govern coordination in software project teams. We examine the relationship between collective ownership, coding standards, expertise coordination, and software project technical quality in a field study of 56 software project teams comprising 509 software developers. We found that collective ownership and coding standards play a role in improving software project technical quality. We also found that collective ownership and coding standards moderated the relationship between expertise coordination and software project technical quality, with collective ownership attenuating the relationship and coding standards strengthening the relationship. Theoretical and practical implications of the findings are discussed.
