United States (US) immigration policies have increasingly focused on national security resulting in universities experiencing declines in international student applications, constraints on international scholar employment, and complications facilitating international research collaborations. 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. Using a representative sample of US and foreign-born scientists in three STEM fields, we explore how recent visa and immigration policies have shaped research collaborations, work with students and postdoctoral scholars, and intentions to leave. We use descriptive statistics, analysis of variance, and logistic regression and find academic scientists report disruptions from visa and immigration policies; negative impacts of immigration policies on US higher education; negative effects on recruitment and retention of international trainees; and increased intentions to leave the US driven by negative perceptions of immigration policy.

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. We conducted three experiments testing the effects of sending academic scientists a pre-notification email message on web survey response rates as compared to no alert email message and variation in the timing of the pre-notification. The data comes from three random national samples of university-based scientists that were conducted during the early months of the COVID-19 pandemic. Two of three experiments suggest that email alert pre-notifications can have a minor effect on improving response rates to web surveys of academic scientists. The timing of those pre-notification messages, though, had no effect on survey response. These findings indicate pre-notification messages remain useful when studying academic scientists. Future research should compare the effects of electronic as compared to postal pre-notification on survey response among scientists, as postal pre-notification requires extensive resources.

Foreign-born academic scientists have been consistently shown to be more productive than the native-born in the United States with regard to research and patents. However, no study has yet analyzed whether the foreign-born are also more likely to commercialize their research after having it patented. This paper utilizes a 2010 survey of academic inventors to analyze whether a selected patent had been licensed or whether technology transfer offices were currently working with a company. Additional analysis was conducted to understand where patents were held (whether by a private company, spinoff, government, or university) for those patents that had been successfully licensed in the past. Findings show that the foreign-born are generally less likely to have their patents licensed or to be working with technology transfer offices, though the significance of the results are mixed. In addition, the foreign-born are more likely to have their licenses held by private companies, while the native-born are more likely to work with spinoffs. These results indicate that technology transfer offices can better serve a key part of the academic workforce. [ABSTRACT FROM AUTHOR]

Though the adverse consequences of lead exposure in children have been well known for over a century, the recent Flint water crisis has drawn renewed attention to the impacts of lead exposure on human health and development. This study considers connections to educational outcomes, asking whether population-level lead exposure in early childhood influences later academic achievement and racial achievement gaps. It assesses the effectiveness of recent local- and state-level lead hazard control programs in mitigating exposure and uses this source of exogenous variation in early childhood exposure across birth cohorts to draw inferences about the long-term effects of lead on mean student test scores. Our findings indicate that lead hazard control grants reduced lead poisoning incidents by over 70% of the baseline prevalence. And each one percentage point reduction in lead poisoning in early childhood translated to a growth of 0.04 standard deviations in student math test scores and 0.08 standard deviations in student reading scores. This same reduction in lead poisoning narrowed both the white-Hispanic math achievement gap and white-Hispanic reading achievement gap by 0.06 standard deviations, implying important downstream consequences for economic inequality.

Much of the available evidence regarding COVID-19 effects on the scientific community in the U.S. is anecdotal and non-representative. We report findings from a based survey of university-based biologists, biochemists, and civil and environmental engineers regarding negative and positive COVID-19 impacts, respondent contributions to addressing the pandemic, and their opinions regarding COVID-19 research policies. The most common negative impact was university closures, cited by 93% of all scientists. Significant subgroup differences emerged, with higher proportions of women, assistant professors, and scientists at institutions located in COVID-19 "hotspot" counties reporting difficulties concentrating on research. Assistant professors additionally reported facing more unanticipated childcare responsibilities. Approximately half of the sample also reported one or more positive COVID-19 impacts, suggesting the importance of developing a better understanding of the complete range of impacts across all fields of science. Regarding COVID-19 relevant public policy, findings suggest divergence of opinion concerning surveillance technologies and the need to alter federal approval processes for new tests and vaccines., Competing Interests: Competing interestsThe authors declare no competing interests., (© The Author(s) 2021, corrected publication 2021.)
