U.S. postdoctoral careers in life sciences, physical sciences and engineering: Government, industry, and academia
Discussions about science and engineering postdoctoral researchers focus almost exclusively on academic postdocs and their chances of eventually securing tenure-track faculty positions. Further, biological sciences dominate policy research and published advice for new PhDs regarding postdoctoral employment. Our analysis uses the Survey of Earned Doctorates and Survey of Doctorate Recipients to understand employment implications for physical sciences and engineering (PSE) and life sciences (LS) graduates who took postdoctoral positions in government, industry, and academic sectors. We examine postdoc duration, reasons for staying in a postdoc, movement between sectors, and salary implications. There is considerable movement between employment sectors within the first six years post-PhD. Additionally, postdocs in PSE are shorter, better paid, and more often in nonacademic sectors than postdocs in LS. These results can help science and engineering faculty discuss a broader range of career pathways with doctoral students and help new PhDs make better informed early career decisions.

Accounting for Teacher Labor Markets and Student Segregation in Analyses of Teacher Quality Gaps
Studies show that historically underserved students are disproportionately assigned to less qualified and effective teachers, leading to a “teacher quality gap.” Past analyses decompose this gap to determine whether inequitable access is driven by teacher and student sorting across and within schools. These sorting mechanisms have divergent policy implications related to school finance, student desegregation, teacher recruitment, and classroom assignment. I argue that analyses of the teacher quality gap that consider how teachers and students are sorted across labor markets offer additional policy guidance. Using statewide data from Texas, I show that teacher quality gaps are driven by sorting across school districts within the same labor market, but this finding differs depending on how “teacher quality” is defined.

Impact of COVID-19: research note on tourism and hospitality sectors in the epicenter of Wuhan and Hubei Province, China
Purpose
The purpose of this paper is to present initial findings from a vulnerability assessment based on the perceptions of practitioners working in four tourism and hospitality sectors in Wuhan and Hubei Province, namely, cruise lines, hotels, travel agencies and touristic attractions.
Design/methodology/approach
The research note focuses on the coronavirus (COVID-19) outbreak from January to March 2020. Using the destination sustainability framework and an “interpretation” mixed methods research design, the authors analyze phone interviews (n = 151) and subsequent online surveys (n = 370) to assess sector-specific perceptions of exposure, sensitivity and system adaptiveness.
Findings
Overall, findings paint a grim picture of each sector in the short-term. All respondents reported an immediate economic loss due to COVID-19, as well as recovery concerns and uncertainties. Immediate actions for addressing these issues centered on internal cost control and governmental subsidies, while anticipated next steps focused on product adjustment, a transformation of business structures and seeking governmental guidance and policies in restoring market confidence. Findings also allude to future strategies/directions.
Research limitations/implications
This study is limited in its focus on practitioner views in the immediate COVID-19 outbreak. Implications highlight a crucial strategic dependence of each sector on effective government/managerial communication and support, with smaller, local businesses needing particular attention in crisis situations.
Originality/value
To the authors’ knowledge, this research note is the first comprehensive study presenting vital information pertaining to the impact of COVID-19 on tourism and hospitality businesses from a large group of business leaders in the site of the initial outbreak (i.e. Wuhan and Hubei Province). With the highly infectious COVID-19 representing an ongoing threat for populations worldwide, this paper hopes this research note provides valuable insights for practitioners in other vulnerable regions, as well as for researchers examining strategies for resilience against this and future disasters.

The benzaldehyde oxidation paradox explained by the interception of peroxy radical by benzyl alcohol
Benzaldehyde readily undergoes autoxidation to form benzoic acid on exposure to air at room temperature. Yet it can be formed in high yield from, for example, benzyl alcohol by oxidation using a variety of procedures and catalysts. Here we report the evidence to resolve this apparent paradox. It is confirmed that benzyl alcohol (and a number of other alcohols), even at low concentrations in benzaldehyde, inhibits the autoxidation. Furthermore we report on the structural features required for inhibition. Electron paramagnetic resonance spin trapping experiments demonstrate that benzyl alcohol intercepts, by hydrogen atom transfer, the benzoylperoxy radicals that play a key role in benzaldehyde autoxidation. A similar inhibition effect has also been observed for the aliphatic octanal/1-octanol system.
Benzaldehdye spontaneously oxidizes to benzoic acid in air, however it can be formed cleanly by the oxidation of benzyl alcohol. Here the authors provide an explanation for this unusual behaviour, showing that small amounts of alcohol can inhibit further oxidation by intercepting a key radical intermediate.

Are High-Poverty School Districts Disproportionately Impacted by State Funding Cuts? School Finance Equity Following the Great Recession
The Great Recession caused states around the country to make substantial budget cuts to public education. As a result, districts that rely more heavily on state funding - those with greater concentrations of students in poverty - may be disproportionately impacted by the Great Recession funding cuts; however, little prior research examines this issue. This study examines how state school finance systems responded to recessionary funding cuts on average nationally. The study then draws on state specific data to examine local district taxation patterns in response to state spending cuts. The study finds that (a) on average across states, high-poverty districts experienced an inequitable share of funding and staffing cuts following the Great Recession; (b) changes in the income-based funding gap varied across states; (c) higher-poverty districts increased local tax rates at a faster rate than low-poverty districts in Texas; and (d) the funding gap increased in Texas by more than in 43 other states; (e) lack of subsidies for facilities funding and other idiosyncrasies within the Texas school finance system prevented highpoverty districts from maintaining equitable funding levels, despite increasing tax rates at a faster rate than otherwise similar wealthier districts; and (f) leveling up funding for high-poverty districts in Texas would cost the state $9.1 billion, a 17% increase in education spending. The study provides evidence on how school districts were impacted by recessionary spending cuts and how they responded, and offers alternative strategies for restoring state education budgets.
