“…We used the Current Population Survey (CPS), a US nationwide household survey conducted jointly by the US Census Bureau and the US Bureau of Labor Statistics (BLS), extracted from IPUMS (a public data service of the University of Minnesota) . Each month, a series of labor force and demographic questions, known as the basic monthly survey, is administered.…”

IMPORTANCEThe health care sector lost millions of workers during the COVID-19 pandemic and job recovery has been slow, particularly in long-term care. OBJECTIVE To identify which health care workers were at highest risk of exiting the health care workforce during the COVID-19 pandemic. DESIGN, SETTING, AND PARTICIPANTS This was an observational cross-sectional study conducted among individuals employed full-time in health care jobs from 2019 to 2021 in the US. Using the data from the Current Population Survey (CPS), we compared turnover rates before the pandemic

“…The primary outcome was health care worker turnover, that is, exiting the workforce either through unemployment (ie, job losers or job leavers per BLS) or exiting the labor force. We examined transitions to unemployment (job loss and job leaver) and leaving the labor force separately.…”

“…In addition, although the equation (M − M e )/(M 0 − M e ) = e −kt relates M (kernel moisture concentration) to M e , this equation and the parameter k must be thoroughly studied to apply this equation in the field (Martinez-Feria et al, 2019;Piggott, 2010;Weller & Bunn, 1993). Additionally, the time t is in hours or minutes (Flood et al, 1972;Shivhare et al, 1992;Weller & Bunn, 1993), which is inconsistent with the diurnal variation of kernel moisture concentration.…”

With the popularization of late-maturing and high-yielding maize (Zea mays L.) hybrids, high kernel moisture concentration at the usual harvest time has resulted in increased kernel breakage and additional drying costs. To achieve low kernel moisture at harvest in China's maize-growing areas, there is a need for the selection of fast dry-down hybrids and the prediction of the ideal harvest time. During 2014-2017, the time-series kernel moisture concentrations of three maize hybrids were measured in the field in three major maize-producing regions in China. Our goal was to accurately predict maize kernel dry-down in the field. We found that the Logistic Power model M = 90/[1 + (T/a) b ] could be used to accurately predict the entire dry-down process of maize kernels across hybrids and regions (concordance correlation coefficient, 0.884-0.996; RMSE, 2.76-5.16%; R 2 , .943-.986; and coefficient of residual mass, −0.09-0.14), where M is the kernel moisture concentration (wet basis), a and b are parameters that reflect the dry-down characteristics of the hybrids, and T is the thermal time (˚C d) from silking based on mean daily temperature over the periods of grain-filling and grain-drying. This work provides a new and convenient model for predicting kernel moisture concentration and evaluating the dry-down characteristics of hybrids using parameters a and b. INTRODUCTIONMaize (Zea mays L.) kernel moisture is a significant factor that influences kernel harvest, post-harvest management, Abbreviations: CCC, concordance correlation coefficient; CRM, coefficient of residual mass.
