Examining spatial network patterns and factors influencing the development of the green economy in typical urban agglomerations in China is crucial for optimizing resource allocation and achieving sustainable economic development. In this study, we utilized the SBM-GML model and a modified gravity model to analyze the roles and status of different regions in the spatial correlation of green economic development in the Yangtze River Delta urban agglomeration. We also employed social network analysis to visualize the spatial correlation structure and influencing factors. The research results indicate that the development of green economy is showing a fluctuating upward trend, accompanied by complex network structure characteristics. Cities such as Chizhou, Nanjing, and Shanghai exert significant control over other cities. The analysis of the block model indicates close intercity communication across various sectors, with heightened activity observed in the southeastern coastal areas. Moreover, the central region effectively enhances connectivity within the urban cluster, leading to notable spillover effects in certain cities. Government macroeconomic regulation, environmental regulation, industrial structure, external development, green innovation, and the level of new urbanization emerge as significant factors influencing the formation of the spatial correlation network of green economic development in the Yangtze River Delta urban agglomeration.

Objectives: To determine the length of delay in initial health-seeking in new pulmonary tuberculosis (PTB) cases among migrant population in the eastern part of China, and factors associated with it. Methods: A cross-sectional study was conducted using a structured questionnaire in six counties in Shanghai, Guangdong and Jiangsu from May to October, 2008, to estimate the extent and factors responsible for delayed initial health-seeking of the new PTB cases. The interval between self-reported onset of TB symptoms and date of first attendance at any medical institution was determined. More than the median duration was defined as delayed health-seeking. Results: A total of 323 new migrant PTB patients participated in the study. Only 6.5% had medical insurance. The median and mean durations to initial health-seeking were respectively 10 and 31 days. There was no significant association between socio-demographic factors and delayed initial health-seeking. Average monthly working days >24 (AOR, 1.61; 95% CI, 1.03-2.51), and hemoptysis or bloody sputum (AOR, 0.48; 95% CI, 0.28-0.85) were significantly associated with delayed initial health-seeking. Conclusions: Interventions to improve health seeking behavior among the migrant population in China must focus on strengthening their labor, medical security and health education.

A new photon-in/photon-out endstation at beamline 02B02 of the Shanghai Synchrotron Radiation Facility for studying the electronic structure of energy materials has been constructed and fully opened to users. The endstation has the capability to perform soft x-ray absorption spectroscopy in total electron yield and total fluorescence yield modes simultaneously. The photon energy ranges from 40 eV to 2000 eV covering the K-edge of most low Z-elements and the L-edge of 3d transition-metals. The new self-designed channeltron detector allows us to achieve good fluorescence signals at the low photon flux. In addition, we synchronously collect the signals of a standard reference sample and a gold mesh on the upstream to calibrate the photon energy and monitor the beam fluctuation, respectively. In order to cross the pressure gap, in situ gas and liquid cells for soft x-ray absorption spectroscopy are developed to study the samples under realistic working conditions. [ABSTRACT FROM AUTHOR]
