The effect of perceived organizational justice on workplace deviant behavior of new nurses: the role of emotional labor and psychological capital

BACKGROUND

New nurses are prone to workplace deviant behavior in the constrained hospital environment, which will not only directly affect the safety of patients, but also reduce the work efficiency of nurses and bring negative results to the hospital. The purpose of this study was to investigate the relationship between perceived organizational justice, emotional labor, psychological capital, and workplace deviant behavior of new nurses.

METHODS

A cross-sectional study was used in this study. A survey was conducted in 5 hospitals in Henan Province, Chain from February to April 2023. The sample size was 546. The questionnaire included general information, perceived organizational justice scale, emotional labor scale, psychological capital scale, and workplace deviant behavior scale. SPSS 26.0 and PROCESS Macro were used for data analysis. PROCESS Model 4 and Model 14 were used to verify the model.

RESULTS

This study displays that perceived organizational justice was negatively correlated with emotional labor and workplace deviant behavior, and emotional labor was positively correlated with workplace deviant behavior. Meanwhile, emotional labor plays a partial mediating role between perceived organizational justice and workplace deviant behavior, accounting for 32.7% of the total effect. Moreover, the path of emotional labor on workplace deviant behavior is moderated by psychological capital.

CONCLUSION

This study further understood the workplace deviant behavior of new nurses, and provided a new perspective for solving this problem. Nurse managers can reduce workplace deviant behavior by enhancing the perceived organizational justice and psychological capital of new nurses and improving emotional labor.

Enhanced Anti-Mold Property and Mechanism Description of Ag/TiO2 Wood-Based Nanocomposites Formation by Ultrasound- and Vacuum-Impregnation

Ag/TiO₂ wood-based nanocomposites were prepared by the methods of ultrasound impregnation and vacuum impregnation. The as-prepared samples were characterized by field emission scanning electron microscopy (FESEM), energy-dispersive spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR), mercury intrusion porosimetry (MIP), and water contact angles (WCAs). The anti-mold properties of the Ag/TiO₂ wood-based nanocomposites were improved by 14 times compared to those of the original wood. The nano-Ag/TiO₂, which was impregnated in the tracheid and attached to the cell walls, was able to form a two-stage rough structure and reduce the number of hydroxyl functional groups on the wood surfaces. The resulting decline of wood hydrophobic and equilibrium moisture content (EMC) destroyed the moisture environment necessary for mold survival. Ag/TiO₂ was deposited in the wood pores, which reduced the number and volume of pores and blocked the path of mold infection. Thus, the anti-mold properties of the Ag/TiO₂ wood-based nanocomposite were improved by cutting off the water source and blocking the mold infection path. This study reveals the anti-mold mechanism of Ag/TiO₂ wood-based nanocomposites and provides a feasible pathway for wood-based nanocomposites with anti-mold functions.
