To modernize food safety governance, we must carry out basic restructuring of its internal logic at the national level to reflect the features of contemporary Chinese society that shape food safety. This will entail establishing an overarching, macro-level conception of food safety that integrates “baseline safety”, “hub safety”, “co-constructed safety” and “endogenous safety”. These four dimensions of safety represent four fundamental requirements of food safety governance in modern Chinese society, which is a “risk society” (Beck 1992 ) and one that is also complex, open and pluralist. These requirements are: maximum legal liability, a unified, authoritative and efficient supervision system, a concept of social co-governance, and enterprises being the primary entities accountable for food safety. This article uses this analytical framework to interpret the basic contents of the newly revised Food Safety Law of the People’s Republic of China, and uses a focus on social co-governance to present the institutional highlights of this law and the transformation of the internal logic of food safety governance. 相似文献

江苏省湿地资源丰富,湿地种类多样,分布广泛,但面临着严重的污染和破坏,且湿地立法相对分散,没有形成完整的湿地保护法律体系。《环境保护法》的修订,特别是生态红线、按日计罚、生态补偿、公益诉讼等制度设计,为江苏省湿地保护立法提供了强有力的制度支撑。在此情形下,制定"江苏省湿地保护条例"显得十分必要。 相似文献

The resonance phenomenon of fluid motions in the gap between ship section, seabed and vertical quay wall is studied numerically and experimentally. The natural frequency of the fluid motions in the gap is derived. A two-dimensional time-domain coupled numerical model is developed to calculate the non-linear wave forces acting on a ship section against vertical quay in a harbor. The fluid domain is divided into an inner domain and an outer domain. The outer domain is the area between the left side of ship section and the incident boundary, where flow is expressed by Boussinesq equations. The rest area is the inner domain, which is the domain beneath the ship section plus the domain between the right side of ship section and vertical quay wall. The flow in the inner domain is expressed by Newton's Second Law. Matching conditions on the interface between the inner domain and the outer domain are the continuation of volume flux and the equality of pressures. The numerical results are validated by experimental data. 相似文献

In South Africa, fishery managers have struggled with a number of challenges in terms of compliance amidst a process of legal and policy reform since the democratic elections of 1994. The past 10 years, and more specifically the past five, have seen a significant change in compliance effort, with a particular focus on increasing law enforcement activities and capacity. This paper highlights two case studies that have been instrumental in restructuring fisheries compliance in South Africa. Although law enforcement has been significantly strengthened, greater political will and government commitment is required to implement alternative strategies that will have a long-term impact on levels of compliance. 相似文献

A method is proposed for calculating the equivalent hydraulic conductivity (EHC) within a finite difference block (FDB). Application of the constant‐flux assumption of Darcy's Law, the EHC equals to the integration of effective hydraulic conductivity (Kw) as a function of pressure head (hw) divided by the head difference at the ends of the FDB. Error analysis show that the constant‐flux (CF) EHC estimates are better than those computed by the commonly used arithmetic‐mean (AM), geometric‐mean (GM), and harmonic‐mean (HM) techniques. CF EHC results are even more superior at larger interblock head difference situations. Simulations of water infiltration experiments show that simulations using the CF EHC or AM or GM weighting technique have only slight difference while applying the Neumann type boundary condition at the ground surface. In case of the Dirichlet type boundary condition, however, the CF EHC is superior to the other two in correctly estimating the depth of infiltration while enlarging the grid size. Therefore, it is recommended to adopt the CF EHC with a larger grid size to the more stable and more efficient results. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献
