The role of employee assistance programs under COVID-19-induced work-family conflict: Effects on service employees' work engagement and burnout.

The COVID-19 pandemic places substantial stress on service employees' work and home lives. Little research has explored the negative effects of perceived stress from COVID-19 on work and home domains in terms of employees' attitudes toward work. We adopt a job demands-resources perspective to examine how perceived stress from COVID-19 affects employees' work (i.e., work engagement and burnout) and home life (i.e., work-family conflict and family-work conflict). In particular, we address whether organizational employee assistance programs can buffer these negative effects. We sampled service employees (n = 248), and results show that perceived stress from COVID-19 increases work engagement and burnout through work-family conflict and family-work conflict. Furthermore, employee assistance programs mean that employees are less likely to experience work-family conflict and family-work conflict when faced with perceived stress from COVID-19. We discuss the theoretical and practical implications of these findings and propose directions for future research.

Characterization of hydrogels prepared from copolymerization of the different degrees of methacrylate-grafted chondroitin sulfate macromers and acrylic acid.

Different degrees (between 20 and 75%) of methacrylate-grafted chondroitin sulfate (CS-MA) were synthesized. These CS-MA macromers were further copolymerized with acrylic acid (AA) at the molar ratio of 1 to 5 to form hydrogels. The sol percents of these CS-MA-AA hydrogels decreased and the cross-linking densities were studied with respect to the degrees of MA substitution onto CS-MA. The cytotoxicity with the increase in degree of MA substitution (DS) onto CS-MA as well as their hydrogels prepared from the corresponding macromers was tested using 293T cells. The cell viability of human dermal fibroblast and mescenchymal stem cells was further tested upon exposure to 75% CS-MA for 1-, 3-, and 7-day incubation period. The hydrogels maintained degradability for long periods of time as evidenced by SEM. A model protein, BSA, demonstrated the prolong-release behaviors of these hydrogels in simulated gastric fluids and pH 7.4 phosphate buffer solutions and a faster release rate in the presence of chondroitinase and esterase at pH 7.4.
