As China proceeds with a process of urbanization unprecedented in human history, it maintains an urban-biased governance regime in many areas, including food safety regulation. Using secondary data and interviews with officials from the Changping district in Beijing, this article systematically defines the main characteristics of China's dual food safety regulation regimes, highlighting differences between urban and rural areas in four dimensions: policy structure, funding source, staff structure and resource allocation. This article also provides an explanatory framework to understand this dual regime's development and persistence from a neo-institutionalism perspective. Three main explanatory variables are advanced: historical legacy, dual incentive structures, and dual economic and industrial patterns. While China's urbanization process and governance structure, including the food safety regulatory regime, are not complete by Western standards, we emphasize this problem is best understood by examining China's unique socioeconomic and cultural context. 相似文献

Abstract: In this study, the specificity, sensitivity, and operability of RSID?‐Urine, a new immunochromatographic test for urine identification, was evaluated and compared with ELISA detection of Tamm‐Horsfall protein (THP). Urine was successfully identified among other body fluids using RSID?‐Urine and ELISA detection of THP. The detection limit of RSID?‐Urine equated to 0.5 μL of urine; although the sensitivity of RSID?‐Urine may be lower than that of ELISA detection of THP, it is thought to be sufficient for application to casework samples. However, results from RSID?‐Urine must be interpreted with caution when the sample may have been contaminated with blood or vaginal fluid, because this might inhibit urine detection. The RSID?‐Urine assay can be performed in just 15 min by dropping the extracted sample onto the test cassette. Therefore, RSID?‐Urine should be an effective tool for the forensic identification of urine, in addition to ELISA detection of THP. 相似文献
