The Revision of Aluminum-containing Food Additive Provisions in China

The aim of this study was to revise the provisions for aluminum-containing food additives in GB 2760-2011 （The National Food Safety Standard for Use of Food Additives）, in order to reduce aluminum exposure among the Chinese population. According to the latest risk assessment results of JECFA and China on aluminum and the actual use of aluminum-containing food additives in certain products, the aluminum-containing food additive-related provisions in GB 2760-2011 were revised. Those revisions included narrowing down the applicable food categories and adjusting the maximum use level of aluminum potassium sulfate and aluminum ammonium sulfate, repealing nine aluminum-containing food additives in puffed food and repealing the use of sodium aluminum phosphate, sodium aluminosilicate and starch aluminum octenylsuccinate in all food.

General Provisions of the Civil Law and Commercial Legislation: Consensus, Problems and Options——Taking Commercial Agency as an Example

In the context of the codification of China's Civil Code, the academic consensus has been to make commercial legislation systematic and establish commercial norms with proper legislative expression. Many direct and indirect commercial norms in General Provisions of the Civil Law provide evidence that civil law has been turned into commercial law. However, a general overview shows that the absence of related norms, including agency in duty, reveals that General Provisions of the Civil Law is lacking commercial law's characteristics. In addition to the Civil Code, using General Rules of Commercial Law is a relatively reasonable choice for commercial legislative arrangements, such as norms in relation to agency in duty. Taking commercial agency as an example, legislators should adopt problem-oriented and limited systematic patterns of "residue law" instead of unified patterns of codification.

Preliminary Study on the Legal Conflict of our Country Marriage Alternative Provisions and Supplementary Provisions in the National Autonomous Areas

Impact of Mandatory Provisions on the Validity of Juristic Acts: A Path for Legal Policy Analysis

Contrary to the approach in judicial practice,Paragraph 1,Article 153,of the Civil Code of the People’s Republic of China,as a rule of invalidity for violating mandatory provisions,does not adopt a dichotomy towards mandatory provisions with effectiveness and administrative characteristics,yet it maintains the legislative philosophy of differentiation.It leaves unspecified whether mandatory provisions that do not explicitly render a juristic act invalid impact the act’s validity,entrusting this determination to the discretion of judges on a case-by-case basis.When judges,under the authority of Paragraph 1,Article 153 of the Civil Code,explore the normative intent of mandatory provisions to assess their effect on the validity of juristic acts,they should engage in legal policy analysis centered on consequence-based argumentation to overcome the limitations of norm typological analysis.This analysis employs a reasoning model predicated on the normative purpose,utilizing a consequencefocused interpretative approach for formulating and arguing propositions of rules applicable to pending cases,thereby arriving at case-specific conclusions.Since the invalidation of juristic acts serves as an auxiliary regulatory tool for the state economy and society,a consequence-oriented interpretation needs to be based on the idea of mutual instrumentalization of public and private laws.This entails predicting the outcomes of negating the validity of a juristic act in industrial regulatory scenarios and assessing these outcomes within the framework of public and private regulatory instruments.

Several New Issues Relating to the Enforcement of the Enforcement Provisions of the TRIPS Agreement under the WTO System

由于知识产权在国际贸易中的特殊性质,TRIPS 协定中的执法条款在 WTO 争端解决机制中将产生一些新问题。一方面,TRIPS 协定规定了知识产权执法的最低要求,WTO 成员方必须履行。WTO 其他成员方可以就 WTO 成员方是否履行了这些知识产权执法义务的争端提交 WTO 争端解决机构。另一方面,TRIPS 协定却没有规定请求方如何证明他们的请求。其中的问题包括:TRIPS 协定中的知识产权执法条款的目标是什么,是这些条款被规定在 WTO 成员方的国内法中,还是 WTO成员方要保证这些条款在实践中的有效性?诉由是制度性的违约,还是个案的违约?救济方式是违约之诉,还是非违约之诉或者特情之诉?有关知识产权的执法措施的审查标准和举证责任如何确定?所有这些问题是通过谈判修改 TRIPS 协定,还是由WTO 争端解决机构(专家组和上诉机构)通过司法判例途径解决?本文结合 WTO争端解决机构(专家组和上诉机构)的司法判例就上述问题进行探讨和研究。

Provision of Preconception Care by Midwives, Nurses and Doctors at Ndola Teaching Hospital in Ndola District, Zambia

Background: The goal of preconception care is to improve the outcome of a mother’s pregnancy and childbirth. Nevertheless, in most developing nations;Zambia included, there are still issues with implementation of preconception care. Therefore, the aim of this study was to establish the provision of preconception care by midwives, nurses and doctors at Ndola Teaching Hospital in Zambia. Methods: A concurrent embedded mixed methodology utilising a descriptive explorative study design, where 107 respondents were randomly selected using the lottery technique for quantitative part and two focused group discussions for qualitative part of the study was used. A self-administered questionnaire was used to collect quantitative data and a focus group discussion guide was used for the focus group discussions. Statistical Package of Social Sciences version 26 with significance set at 0.05 and at 95% confidence level and thematic analysis were used for data analysis. Results: 75% of the respondents in this study were not providing preconception care and only 25% of respondents were providing preconception care;however, this was provided randomly because there were no guidelines to follow. Among the respondents, 81.3% had medium knowledge, 70.1% had good practices and 92.5% had positive attitudes towards preconception care. Further analysis showed that the association between preconception care and knowledge, practices and attitudes was not statistically significant (p = values 0.336;0.344;1.000 respectively). Multivariate logistic regression revealed that participants with high knowledge were five times more likely to provide preconception care (OR = 5.00, CI = 0.42 - 59.7, P = 0.203). Generally, all the participants acknowledged that preconception care was an important package that could prevent maternal and child morbidities and mortalities. Conclusions: The study revealed that most of the respondents were not providing preconception care. Provision of preconception was done by a small fraction of the respondents and it was done in an unorderly manner due to lack of set standards and guidelines. Despite medium levels of knowledge and generally good practices and positive attitudes towards preconception care, its random provision indicates a need for established standards to enhance maternal and child health outcomes.

China's Statutory Provisions on Ensuring Human Rights

Political right Political right is the most important human rights. China’s Constitution provides that the Chinese citizens enjoy freedom of speech, press, assembly, association, procession and demonstration.

Tri-axial accelerometry allows to determine parental food provisioning behaviour in a marine bird

The study of parental food provisioning is essential for understanding the breeding ecology of birds.We conducted the first study using accelerometry to detect food provisioning in birds,using Support Vector Machine(SVM)models to identify when adults feed chicks of three different age classes.Accelerometers were attached to the head of adult female Imperial Shags(Leucocarbo atriceps),and various attributes derived from the acceleration signals were used to train SVM models for each chick age class.Model performance improved with chick age class,with SVM models achieving high overall accuracy(>88%)and highest sensitivity in older chick categories(>91%).However,precision values,especially for younger chicks,remained relatively low(between 26%and 45%).The application of a time filter based on the minimum duration of the observed food provisioning behaviours for each chick age category,improved model performance by reducing false provisioning behaviours,particularly in the model for older chicks,which showed the highest precision(72.4%).This study highlights the effectiveness of accelerometry and machine learning in studying parental food provisioning in birds,providing a rapid and accurate data collection method to complement traditional techniques.The described methodology can be applied to any bird species that exhibits distinctive movements while feeding its offspring and has suitable characteristics for attaching an accelerometer to the body part that best captures this movement.Finally,it is hoped that the results of this study will contribute to future research on key questions in parental investment theory and reproductive strategies in birds.

Joint optimization of maintenance inspection and spare provisioning for aircraft deteriorating parts

With the wide application of condition based maintenance(CBM) in aircraft maintenance practice, the joint optimization of maintenance and inventory management, which can take full advantage of CBM and reduce the aircraft operational cost, is receiving increasing attention. In order to optimize the inspection interval, maintenance decision and spare provisioning together for aircraft deteriorating parts, firstly, a joint inventory management strategy is presented, then, a joint optimization of maintenance inspection and spare provisioning for aircraft parts subject to the Wiener degradation process is proposed based on the strategy.Secondly, a combination of the genetic algorithm(GA) and the Monte Carol method is developed to minimize the total cost rate.Finally, a case study is conducted and the proposed joint optimization model is compared with the existing optimization model and the airline real case. The results demonstrate that the proposed model is more beneficial and effective. In addition, the sensitivity analysis of the proposed model shows that the lead time has higher influence on the optimal results than the urgent order cost and the corrective maintenance cost, which is consistent with the actual situation of aircraft maintenance practices and inventory management.

Adaptive Service Provisioning for Mobile Edge Cloud

A mobile edge cloud provides a platform to accommodate the offloaded traffic workload generated by mobile devices.It can significantly reduce the access delay for mobile application users.However,the high user mobility brings significant challenges to the service provisioning for mobile users,especially to delay-sensitive mobile applications.With the objective to maximize a profit,which positively associates with the overall admitted traffic served by the local edge cloud,and negatively associates with the access delay as well as virtual machine migration delay,we study a fundamental problem in this paper:how to update the service provisioning solution for a given group of mobile users.Such a profit-maximization problem is formulated as a nonlinear integer linear programming and linearized by absolute value manipulation techniques.Then,we propose a framework of heuristic algorithms to solve this Nondeterministic Polynomial(NP)-hard problem.The numerical simulation results demonstrate the efficiency of the devised algorithms.Some useful summaries are concluded via the analysis of evaluation results.

Forest soil conservation based on eco-service provision unit method and its value in Anji County,Huzhou,Zhejiang,China

We propose an eco-service provision unit method for estimating the benefit and spatial differences of forests in controlling soil erosion.A total of 197 eco-service provision units were grouped on 1424.43 km2 of forest according to differences in vegetation,slope,soil,and rainfall.The amount of soil conservation and its economic value were estimated.The forests in Anji County prevent4.08 9 105 tons of soil from eroding annually,thereby avoiding 1.36 9 104 tons of nutrient loss（on-site cost） and preventing 149 tons of nutritive elements from entering water systems（off-site cost）.From an economic perspective,the soil nutrient conservation in the forests of Anji County generated an annual benefit of 43.37 million RMB（Chinese Currency,6.20 RMB = US$1）.On average,each hectare of ecological forest contributed up to 436 RMB annually because of soil conservation.Ecological complexes with higher rainfall intensity,such as broadleaf forest and red soil on slope gradients [25°,contributed the highest soil conservation benefits.This study identified and quantified the dominant contributors and magnitudes of soil conservation provided by forests.This information can benefit decision making regarding differentiated ecological compensation policies.

Exploring Hits-Based Content Provisioning Mechanism in Content-Centric Networking

In-network caching and Interest packets aggregation are two important features of Content-Centric Networking(CCN).CCN routers can directly respond to the Interest request by Content Store(CS)and aggregate the same Interest packets by Pending Interest Table(PIT).In this way,most popular content requests will not reach the origin content server.Thus,content providers will be unaware of the actual usages of their contents in network.This new network paradigm presents content providers with unprecedented challenge.It will bring a great impact on existing mature business model of content providers,such as advertising revenue model based on hits amount.To leverage the advantages of CCN and the realistic business needs of content providers,we explore the hits-based content provisioning mechanism in CCN.The proposed approaches can avoid the unprecedented impact on content providers' existing business model and promote content providers to embrace the real deployment of CCN network.

COVID-19:Effect on gastroenterology and hepatology service provision and training:Lessons learnt and planning for the future

In late 2019,reports arose of a new respiratory disease in China,identified as a novel coronavirus,severe acute respiratory syndrome coronavirus 2.The World Health Organisation named the disease caused by the virus‘coronavirus disease 2019(COVID-19)’.It was declared a pandemic in early 2020,after the disease rapidly spread across the world.COVID-19 has not only resulted in substantial morbidity and mortality but also significantly impacted healthcare service provision and training across all medical specialties with gastroenterology and Hepatology services being no exception.Internationally,most,if not all‘nonurgent’services have been placed on hold during surges of infections.As a result there have been delayed diagnoses,procedures,and surgeries which will undoubtedly result in increased morbidity and mortality.Outpatient services have been converted to remote consultations where possible in many countries.Trainees have been redeployed to help care for COVID-19 patients in other settings,resulting in disruption to their training-particularly endoscopy and outpatient clinics.This has led to significant anxiety amongst trainees,and risks prolongation of training.It is of the utmost importance to develop strategies that continue to support COVID-19-related service provision,whilst also supporting existing and future gastroenterology and Hepatology services and training.Changes to healthcare provision during the pandemic have generated new and improved frameworks of service and training delivery,which can be adopted in the post-COVID-19 world,leading to enhanced patient care.

Spatial matching and flow in supply and demand of water provision services: A case study in Xiangjiang River Basin

Global climate change and increased human consumption have aggravated the uneven spatiotemporal distribution of watershed water resources, affecting the water provision supply and demand state. However, this problem has often been ignored. The present study used the Xiangjiang River basin(XRB) as the study area, and the Integrated Valuation of Ecosystem Services and Trade-offs(InVEST) model, demand quantification model,supply–demand ratio, and water flow formula were applied to explore the spatial heterogeneity, flow, and equilibrium between water supply and demand. The results demonstrated significant spatial heterogeneity in the upstream, midstream, and downstream regions.The areas of water shortage were mainly located the downstream of the Changsha–Zhuzhou–Xiangtan urban agglomeration, and the Hengyang basin was the most scarcity area. Affected by terrain gradients and human needs, water flow varied from-16.33 × 10^(8) m^(3) to 13.69 × 10^(8) m^(3)from the upstream to the downstream area, which provided a possibility to reduce spatial heterogeneity. In the future, measures such as strengthening water resource system control,sponge city construction, and dynamic monitoring technology should be taken to balance the supply and demand of water in different river sections of the basin. This study can provide references for regulating water resources allocation in different reaches of the basin.
