How to Evaluate the Green and High-Quality Development Path? An FsQCA Approach on the China Pilot Free Trade Zone.

In today's world, green development has become an important trend, and many countries regard the development of green industry as an important measure to promote economic restructuring. Green development is consistent with sustainable development in ideology. China's economy is in the stage of high-quality development. As an important foundation for China's external economic development, the free trade zone can play a good role in promoting its green and high-quality development. Based on the data of 18 free trade zones in China in 2020, this paper explores the green and high-quality development path of the China Pilot Free Trade Zone. Firstly, the green development index is constructed according to the existing research and experience, and then the fuzzy set qualitative comparative analysis method is used to evaluate the green and high-quality development path. The results show that the development of pilot free trade zones is not the result of a single condition but the result of a combination of green policy effectiveness, foreign investment participation, green production growth rate, and other conditions. Combined with the green and high-quality development path, this paper further provides enlightenment for the development of the China Pilot Free Trade Zone.

Explaining Job Satisfaction Among Residents in Standardized Residency Training Programs: A Serial Multiple Mediation Model.

BACKGROUND: Despite a flood of research on job satisfaction, few studies have examined how and why social support influences job satisfaction. This study aimed to explore how social support has an indirect effect on job satisfaction by examining its impact on emotional exhaustion and anxiety symptoms among residents of the physicians standardized residency training program in China. METHODS: This cross-sectional study adopted questionnaires to collect data from residents in the standardized residency training program in China. The PROCESS macro for SPSS based on ordinary least-squares regression and the bootstrap method was used. The indirect effect of social support was examined using bootstrapping procedures. A serial multiple mediation model was examined in which social support was associated with job satisfaction via emotional exhaustion and anxiety symptoms. RESULTS: There were 269 residents who provided usable data for the analysis. The mean age of residents was 25.98 years old. Close to half (52%) of the participants were female. The total indirect effect of social support on job satisfaction was significant (ab=0.21, SE=0.05, CI=0.12 to 0.32). The specific indirect effect 1 (social support→emotional exhaustion→job satisfaction) was significant (a1b1=0.12, SE=0.04, CI=0.05 to 0.19). The specific indirect effect 2 (social support→anxiety symptoms→job satisfaction) was significant (a2b2=0.07, SE=0.03, CI=0.02 to 0.13).The specific indirect effect 3 (social support→emotional exhaustion→anxiety symptoms→job satisfaction) was also found to be significant through both optimism and work engagement (a1a3b2=0.03, SE=0.01, CI=0.01 to 0.05). CONCLUSION: It seems critical for hospital management to develop a supportive work environment to improve the effects of emotional exhaustion and anxiety symptoms and to provide sufficient support to improve job satisfaction among residents in standardized residency training programs.

Explaining Organizational Citizenship Behavior Among Chinese Nurses Combating COVID-19.

BACKGROUND: Little is known about the associated factors with organizational citizenship behavior among Chinese nurses combating COVID-19. The aim of the present study was to investigate the relationships between autonomy, optimism, role conflict, work engagement, and organizational citizenship behavior based on moderated mediation models among Chinese nurses combating COVID-19. METHODS: This cross-sectional study was performed on a sample of 368 nurses supporting the COVID-19 epidemic in Wuhan Leishenshan Hospital, China. According to the Job Demands-Resources model, two moderated mediation models were tested, in which autonomy/optimism was associated with organizational citizenship behavior through work engagement, when role conflict served as a moderator. RESULTS: This current study found the mediating effect of work engagement and the moderating effect of role conflict on the relationship between autonomy/optimism and organizational citizenship behavior among nurses. Of note, nurses working in the COVID-19 epidemic viewed role conflict as challenge job demands rather than hindrance job demands. CONCLUSION: Based on the findings, organizational citizenship behavior can be affected by work engagement and role conflict. Nursing management is suggested to put emphasis on work engagement and role conflict among nurses supporting the COVID-19 epidemic.

Where are signal molecules likely to be located in anaerobic granular sludge?

Quorum sensing is a concentration-sensing mechanism that plays a vital role in sludge granulation. In this study, the regularities of distribution of different signal molecules, including intra- and interspecific signal molecules (diffusible signal factor, DSF), interspecific signal molecules (autoinducter-2, AI-2) and intraspecific signal molecules (acyl-homoserine lactones, AHLs), from three types of anaerobic granular sludge were investigated. The results showed that 70-90% of DSF was distributed in sludge, while AI-2 in the Water phase accounted for over 80% of the total content. Interestingly, there was a positive correlation between DSF and AI-2, which played opposite roles in granulation. Moreover, more than 55% of short and medium acyl chain AHLs tended to spread in aqueous water, while the long acyl chain AHLs were closer to granular sludge than the short and medium acyl chain AHLs. With the exception of one type of sludge, the percentage of long acyl chain AHLs in the sludge phase was greater than 70%. The different distributions of signal molecules were primarily determined based on their physicochemical properties, including molecular weight and solubility in water or organic solutions. In addition, the basic properties of sludge, such as the granular level or the production of EPS, were closely related to the diversity, distribution and concentration of signal molecules. As a medium in granulation, extracellular polymeric substances production was regulated by different signal molecules from different parts of anaerobic granular sludge. This study provides a foundation for investigation of quorum sensing in the system of anaerobic granular sludge.
