Conflict in online discussions of science has the potential to polarize individuals’ perceptions of science, yet science communication scholarship has paid little attention to systematic study of how verbal attacks play out in online discussions of science. This study analyzes sarcasm and incivility in Twitter discussions of climate change during an extreme weather event ( n = 4,094). We found instances of incivility and sarcasm were low overall. Incivility was used in association with political topics, and both incivility and sarcasm were used alongside skeptical perspectives of climate change and by those who mention right-leaning politics in their profiles.

Visual bookmarking app Pinterest, known for its aspirational and consumptive qualities of users' “pinning” work, has recently made concerted forays into the online advertising and marketing space. At the same time, its visual and collaborative qualities offer unique potential for application in pedagogy. This paper describes a pedagogical assessment study examining a Pinterest-based discussion board series. Results suggest Pinterest enhances students’ sense of learning through contributing to enjoyment, sense of community, and perceived collaborative learning. These results support the utility of Pinterest-oriented discussions to foster collaboration and learning in online digital advertising and media courses.

It is unknown whether social presence in internet-based MBA courses enhances students’ career success. This study examined general self-efficacy and goal orientation mediation models to determine what strengthens MBA students’ social presence and their career planning self-confidence. Data included 278 online MBA students in an AACSB-accredited college of business. The regression analyses demonstrated that perceived general self-efficacy and goal orientation related to students’ career planning self-confidence. The mediation analyses revealed that internet self-efficacy, perceived general self-efficacy, and goal orientation had an indirect mediating effect on social presence and career planning. Implications are offered for business communication educators.

The global COVID-19 pandemic led to an increase in faculty who taught using video conferencing software, such as Zoom, across different modalities in higher education. Drawing from social comparison theory, this study examines upward and downward social comparison as parallel mediators of the interrelationships between faculty burnout, teaching anxiety, and teaching satisfaction during the COVID-19 pandemic using a cross-sectional sample of 219 faculty. Findings reveal the mediating effect of upward social comparison on the relationship between faculty’s burnout and teaching anxiety. Additionally, upward social comparison had a mediating effect on faculty’s burnout and teaching satisfaction. Implications for teaching and learning using video conferencing tools are also offered.
