Chronic obstructive pulmonary disease (COPD), lung cancer (LC) and tuberculosis (TB) are common chronic lung diseases that generate a large disease burden and significant health care resource use in China. The aim of this study was to quantify spatial patterns and effects of air pollution and meteorological factors on hospitalization of COPD, LC and TB in Beijing. Daily counts of hospitalization for 2010 were obtained from the Beijing Urban Employees Basic Medical Insurance (UEBMI) system. Bayesian hierarchical Poisson regression models were applied to identify spatial patterns of hospitalization for COPD, LC and TB at the district level and explore associations with inhalable particulate matter (aerodynamic diameter <10 μm, PM 10 ), sulfur dioxide (SO 2 ), nitrogen dioxide (NO 2 ), mean temperature and relative humidity. There were 18,882, 14,295 and 2,940 counts of hospitalizations for COPD, LC and TB respectively, in Beijing in 2010. Clusters of high relative risk were in different locations for the three diseases. The effect of relative humidity on COPD hospitalization was most significant with a relative risk (RR) of 1.070 (95%CI: 1.054, 1.086) per one percent increase. For lung cancer hospitalization, exposure to ambient SO 2 was associated with a RR of 1.034 (95%CI: 1.011, 1.058) per µg m -3 increase. For tuberculosis, the effect of mean temperature was significant with a RR of 1.107 (95%CI: 1.038, 1.180) per °C increase. Risk factors and spatial patterns were different for hospitalization of non-infectious and infectious chronic lung disease in Beijing. Even over a short time period (one year), associations were apparent with air pollution and meteorological factors.
Given the current shortage of kindergarten teachers, this study examines the relationship between empowering leadership and job satisfaction among kindergarten teachers in China from the perspective of their job characteristics and the Chinese cultural context. The participants were 557 Chinese kindergarten female teachers whose average number of years of experience was 2.82 (SD = 3.02). They completed a self-report survey regarding empowering leadership, vigor, affective commitment, and job satisfaction. The study results show that vigor and affective commitment could mediate the relationship between empowering leadership and job satisfaction. Finally, we discuss the findings of this study in depth. At the same time, we suggest that administrators should focus on the empowering leadership of Chinese kindergarten teachers, strive to increase their level of dynamism, and finally, strengthen the emotional connection between the organization and the Chinese kindergarten teachers. Thus, we suggest that educational administrators should empower kindergarten teachers more, rather than allowing them to be mere enforcers. In addition, how to enhance the individual dynamics of early childhood teachers and their emotional connection to the organization may also be something for educational administrators to consider.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
