The COVID-19 pandemic brought additional travel restrictions, embassy closures, and health and safety concerns that exacerbated these challenges. Science mobility is critical for science education, training, competitiveness, and innovation.

COVID-19 and the academy: opinions and experiences of university-based scientists in the U.S.

Much of the available evidence regarding COVID-19 effects on the scientific community in the U.S. is anecdotal and non-representative.

The effects of electronic alert letters for internet surveys of academic scientists.

Survey alert letters improve response rates and assure potential respondents that the research is legitimate and of high quality. Pre-notification by mail increases response rates for web surveys because it represents a second mode of communication and contributes to increases in respondent trust and study legitimacy. Due to work-from-home orders in response to COVID-19, postal alert letters are unlikely to reach research participants at their place of employment.
