This study analyzes 295 tweets by four U.S. companies engaged in discovering a vaccine for COVID-19. Tweets were analyzed to understand how their Twitter feeds balanced corporate and product branding (vaccine, medicines, etc.) and disseminated scientific information relating to COVID-19. The results suggest that these companies were actively embedding technical information about COVID-19 in their corporate and product branding. Tweets providing technical and scientific information about the progress made toward developing a COVID-19 vaccine garnered high levels of user engagement from their target audience. Findings from this study indicate the growing importance of technical communication in corporate settings during a public health crisis.

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.
