Parenting and parent-child home practice during the COVID-19 pandemic: a case in central China.

The current study aims to explore parents' perceptions of parenting and parent-child activities at home with children aged 3-6 during the pandemic in China. A parenting survey was conducted to investigate parental role, age, educational background, work productivity, and different parenting categories during the lockdown period. We also examined the experiences of young children's participation in extracurricular activities before and after the stay-at-home policy was implemented as well as their activities with parents during the lockdown period. The results showed that parents' work productivity affected their perceptions of well-being during the COVID-19 pandemic. Children spent less time on extracurricular activities during the lockdown period, but some particular activities increased in frequency, especially academic extracurricular activities.

Work-family conflict and anxiety among nurses of the maternal and child health institutions: the mediating role of job satisfaction.

Introduction: Over the past decades, anxiety has garnered significant attention from nursing population. Investigations have centered on the correlation between work-family conflict (WFC) and anxiety as well as the link between job satisfaction and anxiety among nurses. However, the role of job satisfaction plays in the relationship between work-family conflict and anxiety remains relatively unexplored. Methods: In April 2021, a cross-sectional survey was conducted among nurses (N = 3,770) working at the maternal and child health institutions in Henan province, China. Multiple linear regression model was used to explore the factors associated with anxiety. Model 4 in Hayes's PROCESS macro and Bootstrap method was performed to examine the mediating role of job satisfaction in the relationship between work-family conflict and anxiety. Results: The median (interquartile range) anxiety score was 5.00 (6.00). Work-family conflict was shown to be significantly correlated to job satisfaction (r = -0.517, p < 0.001) and anxiety (r = 0.457, p < 0.01). There was a strong negative correlation between job satisfaction and anxiety (r = -0.379, p < 0.01). The study also found that nurses aged 31-40 years, those with a junior college education (p = 0.001), those with an undergraduate or above education (p < 0.001), those who reported experiencing work-family conflict (p < 0.001), and those with lower job satisfaction (p < 0.001) were more likely to experience anxiety. Additionally, job satisfaction partially (a*b = 20.90%) mediated the relationship between work-family conflict and anxiety. Conclusion: The association between work-family conflict and anxiety among nurses in maternity and child health institutions was moderated by job satisfaction. Therefore, it is critical to enhance working conditions, minimize work-family conflict, and promoting job satisfaction among nurses may help to mitigate the negative effects of work-family conflict on anxiety.

Synergism of selective thermal denaturation and glycosylation improves quality characteristics of green soybean tofu.

BACKGROUND: Tofu is rich in nutrients and contains high-quality protein. However, commercial tofu products usually have weak gel strength and low water holding capacity (WHC). In the present study, the effects of selective thermal denaturation (STD) time (0-20 min, 5-min interval; 85 °C) and glycosylation (100 °C; 0, 10 and 20 g kg-1 glucose) on the quality characteristics of green soybean tofu were studied through by the evaluation method of the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) model for the best synergism condition of STD and glycosylation. RESULTS: Compared to STD or glycosylation, combination treatment of STD and glycosylation improved hardness, WHC, yield, protein and fat contents of green soybean tofu. Furthermore, the gel strength, WHC, yield, protein and fat contents of tofu was increased by 135.21%, 20.18%, 12.21%, 24.91%, 44.15% compared to untreated tofu. Meanwhile, synergistic treatment of STD and glycosylation significantly improved microstructure network structure of green soybean tofu and made it more homogeneous and denser. However, the green soybean tofu was faded and turned yellow under the combination of the STD and glycosylation. CONCLUSION: The results obtained through TOPSIS showed that the combination of thermal treatment (85 °C for 15 min) and glycosylation (20 g kg-1 glucose at 100 °C) had the greatest improvement in the characteristics of green soybean tofu. Hence, the combination treatment of STD and glycosylation should be useful for improving the quality characteristics of green soybean tofu and providing the technical references for industrial processing of tofu. © 2022 Society of Chemical Industry.

Comparison and Characterization of the Structure and Physicochemical Properties of Three Citrus Fibers: Effect of Ball Milling Treatment.

Effects of ball milling (BM) on the structure and physicochemical properties of three types of citrus fibers were investigated. With the extension of the grinding time, the particle size of citrus fibers significantly decreased. Fourier transform infrared spectroscopy (FTIR) showed that the three citrus fibers had similar chemical groups, and more -OH and phenolic acid groups were exposed after BM, and pectin and lignin were not degraded. Scanning electron microscope (SEM) results showed that the appearance of particles changed from spherical to fragmented, irregular shapes. The water holding capacity (WHC), oil holding capacity (OHC), and water swelling capacity (WSC) of citrus fibers LM, JK, and FS reached the maximum value after BM of 2 h (increasing by 18.5%), 4 h (increasing by 46.1%), and 10 h (increasing by 38.3%), respectively. After 10 h BM, citrus fibers FS and JK had the highest adsorption capacity of cholesterol and sodium cholate, increasing by 48.3% and 48.6%, respectively. This indicates that BM transforms the spatial structure of citrus fibers and improves their physicochemical properties.
