No country is an island in regulating food safety:How the WTO monitors Chinese food safety laws through the Trade Policy Review Mechanism(TPRM)

Established within the framework of the World Trade Organization （WTO）, the Trade Policy Review Mechanism （TPRM） reviews periodically the trade policies of all WTO Members. The review includes many aspects of food safety regulation. China＇s trade policy is reviewed every two years. This paper analyses in detail the reviews of China＇s trade policy in 2006, 2008, 2010, 2012 and 2014. It focuses in particular on food safety laws and types of standards, alignment of domestic standards with international standards, the role of different domestic institutions, transparency and notification of food safety measures under the WTO agreements on Sanitary and Phytosanitary Measures （SPS） and on Technical Barriers to Trade （TBTAgreement）, import and export, and geographical indications （GIs）. It concludes that the WTO TPRM can contribute, within its mandate, to reform of Chinese food safety laws and improvement of food safety in China. it notes that China has already undertaken substantial reforms of its system for regulating food safety. It recommends that China should continue to participate actively in the TPRM, follow its own path with regard to alignment and learn selectively from other WTO Members.

Game analysis on Huaihe River anti-pollution administration mechanism and policy research

Based on the literature review of environmental anti-pollution researches, this paper analyzes the administra- tive mechanism of Huaihe River anti-pollution with game theory. Based on the quantitative analysis on three correspond- ing game models with four players including local residents, enterprises, local governments and competent authorities at higher levels, this paper demonstrates four main shortcomings of current administrative mechanism of Huaihe River anti-pollution system, including low emission cost, low connivance cost, overemphasis on heavy fine of the enterprises, neglect of the punishment on the local departments and intersected administrative mechanism. This paper sets up anti- pollution administrative mechanism, combining economic method with noneconomic method, government control with market mechanism, and introducing public participation. At last, this paper proposes policies, such as implementing emissions trading system, reforming public participation system, and reforming government’s environmental protection mechanism to promote law enforcement.

Perception Enhanced Deep Deterministic Policy Gradient for Autonomous Driving in Complex Scenarios

Autonomous driving has witnessed rapid advancement;however,ensuring safe and efficient driving in intricate scenarios remains a critical challenge.In particular,traffic roundabouts bring a set of challenges to autonomous driving due to the unpredictable entry and exit of vehicles,susceptibility to traffic flow bottlenecks,and imperfect data in perceiving environmental information,rendering them a vital issue in the practical application of autonomous driving.To address the traffic challenges,this work focused on complex roundabouts with multi-lane and proposed a Perception EnhancedDeepDeterministic Policy Gradient(PE-DDPG)for AutonomousDriving in the Roundabouts.Specifically,themodel incorporates an enhanced variational autoencoder featuring an integrated spatial attention mechanism alongside the Deep Deterministic Policy Gradient framework,enhancing the vehicle’s capability to comprehend complex roundabout environments and make decisions.Furthermore,the PE-DDPG model combines a dynamic path optimization strategy for roundabout scenarios,effectively mitigating traffic bottlenecks and augmenting throughput efficiency.Extensive experiments were conducted with the collaborative simulation platform of CARLA and SUMO,and the experimental results show that the proposed PE-DDPG outperforms the baseline methods in terms of the convergence capacity of the training process,the smoothness of driving and the traffic efficiency with diverse traffic flow patterns and penetration rates of autonomous vehicles(AVs).Generally,the proposed PE-DDPGmodel could be employed for autonomous driving in complex scenarios with imperfect data.

Dilemma for the Redevelopment of Village and Town Construction Land, Formation Mechanism and Policy Suggestions

Under the context of economy new normal and rapid urbanization, the shift of economic growth, structural adjustment pains as well as pre-stimulus digestion comes coincidentally. The boundary red line of urban growth, the red line of the number of basic farms and the ecology red line makes the local to conserve land. Land stock for village and town construction is a huge amount of potential resources. Redevelopment of land for village and town construction provides ensured land security for the smooth progress of urbanization. Combining village and town construction land use characteristics and making in-depth analysis of the difficulties in the redevelopment of village and town construction and its inner mechanism, policies and suggestions were proposed for the redevelopment of village and town construction land in terms of land property, land price, market allocation, planning, surveillance and so on, so as to provide valuable reference for the smooth redevelopment of village and town construction land, and the system design of villages and towns.

Countermeasures for Establishing a Long-term Security Mechanism for Landless Farmers

In the process of urbanization,farmers will inevitably lose their land,which is resulted from the large-scale requisition of rural collective land.The imperfect social security system in rural areas has resulted in a large number of landless farmers being transformed into urban poor people.Therefore,proper resettlement of landless farmers and the establishment of a long-term security mechanism for ensuring the basic livelihood of landless farmers are important issues that need to be resolved in the process of China’s social and economic development.

Transmission Mechanisms of Monetary Policy in Saudi Arabia： Evidence From SVAR Analysis

In this research, the authors evaluate different channels of the monetary policy transmission mechanisms in Saudi Arabia over the last 15 years with a baseline of structural vector autoregressive （SVAR） models. Contemporaneous coefficient in the structural model indicates that while Saudi Arabia pegs its currency to US dollar, monetary policy instrument reacts positively to unexpected changes in the monetary aggregate. In addition to the traditional interest rate channel, the authors have also found the effects of credit channel. Moreover, variance decomposition results show that past shocks of credit, nominal effective exchange rate （NEER）, federal funds rate （FFR） and treasury bill （TB） are found to be important for credit growth in shorter and longer horizons. The exchange rate channel has been less significant in comparison to other channels.

Evolution of Microstructure and Mechanical Property during Long-Term Aging in Udimet 720Li

Thermal stabilities of microstructure and mechanical property have been investigated on superalloy U720Li, which is of great interest of application for jet engine and land-based turbine disc. The results showed that, the primary and secondary gamma' particles maintain good thermal stability at 650 and 700 degreesC with aging time up to 3000 h, while the tertiary gamma' is apparently dependent on aging temperature and time. The tertiary gamma' particles undergo a procedure of coarsening, dissolution and eventually complete disappearance with the increasing of aging time and temperature. They exhibit unusual high sensibility upon aging temperature, which is attributed to the lattice misfit between the gamma' precipitates and the matrix in the alloy. The grain boundary phase M23C6 remains stable without forming of sigma phase even with aging time up to 3000 h at 700 degreesC. Microhardness decreases apparently with increasing aging time and aging temperature. Theoretical analysis based on dislocation mechanism indicates that the change of microhardness should be attributed to the evolution of the tertiary gamma' during aging.

Comprehensive analyses of initiation and failure mechanisms of the 2017 Xinmo catastrophic rockslide

The failure of the 2017 Xinmo catastrophic rockslide in Maoxian County, Sichuan, Southwest China was a combined effect of long-term and shortterm triggering factors. Field investigation, historical data collection, laboratory tests, chemical and microstructure analysis and numerical simulations were adopted herein to reveal the initiation and failure mechanism of the Xinmo rockslide. The analytical results showed that this failure involved the coupling of several triggering factors. The initial cracks in the rock mass were induced by historical earthquakes due to the convex topography and the direction effect. Rock masses from the source area of the Xinmo rockslide contain water-sensitive minerals, i.e., albite and chamosite, and the easily oxidized chemical element Fe, resulting in obvious strength deterioration under the action of water. The scanning electron microscopy(SEM) experimental results indicated that the internal structure of the rock mass is conducive to weathering. The compressive and shear strengths of the rock mass were reduced due to freeze-thaw cycles and weathering. The antecedent rainfall further deteriorated the stability of the slope, and stress and deformation accumulated continually in the locked section. Finally, the locked section sheared out, and the slope failed. An entrainment effect was observed in the Xinmo rockslide due to the presence of old landslide deposits and the antecedent rainfall, resulting in an amplification of the catastrophic rockslide. A simplified three dimensional analysis model was established in this study to reveal the influence of the triggering factors on the failure mechanism of the Xinmo rockslide.

Survey of <i>C. difficile</i>-Specific Infection Control Policies in Local Long-Term Care Facilities

Introduction: The incidence and severity of Clostridium difficile infection (CDI) has been increasing and long-term care facility (LTCF) residents are at high risk given their age, co-morbidities, and high antibiotic exposure. Infection control policies are crucial for controlling CDI, but there are currently no regulatory guidelines in the United States. Therefore, we evaluated infection control policies in local LTCFs to define the CDI-specific policies and the administrative and staff understanding of CDI, so as to identify perceived barriers for compliance. Methods: IRB approval was sought and exemption granted, all 8 local LTCFs were asked to participate. Each facility was visited by study personnel who interviewed the administrative Infection Control Practitioner (ICP) and 3-4 Licensed Practical Nurses (LPNs) with distinct survey format. Infection control policies were then compared to the SHEA recommendations for CDI in LTCFs. Results: Of the eligible facilities, 75% (n = 6) participated. ICP (n = 6) and LPNs (n = 21) were interviewed. All facilities accept residents with active CDI and 2 had written CDI-specific infection control policies. All facilities had hand hygiene or glove use policies and 2 had policies for the use of sporicidal environmental cleaning. No facility restricted antibiotic use. Each facility has a policy to instruct their staff through in-services, either annually or upon new hire, but 33% (n = 7) LPNs reported no facility-based CDI training. While 80% (n = 17) of LPNs felt comfortable with the facility CDI policies, only 11 accurately restated it. ICPs felt the most relevant barrier to staff compliance was time constraints (n = 4, 67%), however, LPNs felt it was limited knowledge (n = 10, 48%) and poor communication (n = 2, 10%). Discussion and Conclusions: With the increasing incidence and severity of CDI in LCTF, few of the facilities surveyed had CDI-specific policies. Despite CDI-specific training, there is a perceived knowledge and communication gap for staff caring for residents with CDI.

Establish the Long-effective Mechanism of Food Security in China

In despite of fluctuation in recent years, the grain yield in China has been increasing, which relieves the conflict between supply and demand and turns the situation of food security good. However, because of the rapid increase in food consumption, the conflicts of food quality and structure in the supply and demand equilibrium has become more and more obvious and the long-effective mechanism of food security has not been estab-lished yet. It is found that the factors affecting food security in China include the scarcity and dissipation of resources, farmers’ low enthusiasm in planting grain crops and the inappropriateness of the emphasis and measures of macro-economic regulation and control. Therefore, the authors advance to optimize resources allocation, strengthen macro-economic regulation and control and policy stimulation and establish the mechanism of allocating grain production cost, to set up the long-effective mechanism of China food security and keep it stable in the long term.

A Hybrid Handover Forecasting Mechanism Based on Fuzzy Forecasting Model in Cellular Networks

As the increasing demand for mobile communications and the shrinking of the coverage of cells, handover mechanism will play an important role in future wireless networks to provide users with seamless mobile communication services. In order to guarantee the user experience, the handover decision should be made timely and reasonably. To achieve this goal, this paper presents a hybrid handover forecasting mechanism, which contains long-term and short-term forecasting models. The proposed mechanism could cooperate with the standard mechanisms, and improve the performance of standard handover decision mechanisms. Since most of the parameters involved are imprecise, fuzzy forecasting model is applied for dealing with predictions of them. The numerical results indicate that the mechanism could significantly decrease the rate of ping-pong handover and the rate of handover failure.

Inthis context, the Clean Development Mechanismalso compliments a range of environmental and energypolicies which are strategizing to encourage thesustainable development of China’s economy.

An Initial Residual Stress Inference Method by Incorporating Monitoring Data and Mechanism Model

Initial residual stress is the main reason causing machining deformation of the workpiece,which has been deemed as one of the most important aspects of machining quality issues.The inference of the distribution of initial residual stress inside the blank has significant meaning for machining deformation control.Due to the principle error of existing residual stress detection methods,there are still challenges in practical applications.Aiming at the detection problem of the initial residual stress field,an initial residual stress inference method by incorporating monitoring data and mechanism model is proposed in this paper.Monitoring data during machining process is used to represent the macroscopic characterization of the unbalanced residual stress,and the finite element numerical model is used as the mechanism model so as to solve the problem that the analytic mechanism model is difficult to establish;the policy gradient approach is introduced to solve the gradient descent problem of the combination of learning model and mechanism model.Finally,the initial residual stress field is obtained through iterative calculation based on the fusing method of monitoring data and mechanism model.Verification results show that the proposed inference method of initial residual stress field can accurately and effectively reflect the machining deformation in the actual machining process.

An Analysis of the Operation Mechanism of Chemical Industry Park Ecosystem Based on Theory of Ecological Organization

Based on the theory of ecological organization,this paper analyzes the operation mechanism of chemical industry park(CIP)ecosystem by means of dynamic simulation.The research shows that the CIP ecosystem is a complex ecological system whose operation mechanism includes two levels,namely individual enterprises and ecosystem.At the level of individual enterprise,there are competition,symbiosis,invasion and other interactions between enterprises in the CIP ecosystem.Through the pre-determined judgment of the competition effect coefficient and the symbiosis effect coefficient,we calculate how the enterprises influence each other,and then generate their respective operation paths,andfinally realize the long-term balance of the system.At the level of ecosystem,the CIP ecosystem makes self-organizing and self-adaptive adjustments and changes due to the changes of the exter-nal environment in policy,manpower,technology,capital,market,etc.,thus reaching the equilibrium state of coordinated operation and stable symbiosis with the external environment.

Long-term care policy simulation of disabled elderly

With the accelerating process of population aging in our country, the physical function of the elderly will decline, the possibility of suffering from acute and chronic diseases will increase, and the occurrence of disability will become more common and normal. The potential demand for elderly care is rapidly increasing. With the growth, the care of the disabled elderly has become increasingly acute. At the same time, due to the intensification of family miniaturization and population migration, the traditional family-based long-term care has been difficult to sustain. How to incorporate long-term care into our social security system as soon as possible has become the focus of the whole society. The thesis through the combination of public policy simulation methods and the research data, the long-term care insurance system implemented at the beginning of 2018 in Shanghai is a policy blueprint. It uses statistical software SPSS, MATLAB, etc. to achieve data collation, analysis and prediction, and at the same time integrates the pilot of the long-term care insurance system. The implementation of policies in cities such as Qingdao and Nantong has been simulated. Finally, on the basis of simulation results, suggestions have been made for the future development of China＇s long-term care insurance system.
