The construction of a food certification system plays a vital role in upgrading export quality, which previous studies have largely overlooked. We match China's industry-level data of Green Food Certification with its HS6-digit export data of agri-food products to quantify the impact of Green Food Certification on export quality. We identify the significant and positive effect of Green Food Certification on export quality. The 2SLS estimation based on instrumental variables and a range of robustness checks confirm the validity and robustness of the benchmark conclusions. Further analysis discloses that Green Food Certification improves export quality by raising agricultural production efficiency and brand premiums. Heterogeneity analysis shows that the effect of Green Food Certification varies across regions, notably improving the quality of agri-food products exported to developed regions and regions with high levels of import supervision. Furthermore, among various product types, Green Food Certification significantly improves the export quality of primary products and products vulnerable to non-tariff measures. The above findings could guide the future development of agri-food quality certification systems, potentially leading to a transformation and promotion of the agri-food trade. 展开更多

Acoustic models of railway vehicles in standstill and pass-by conditions can be used as part of a virtual certification process for new trains.For each piece of auxiliary equipment,the sound power measured on a test bench is combined with meas-ured or predicted transfer functions.It is important,however,to allow for installation effects due to shielding by fairings or the train body.In the current work,fast-running analytical models are developed to determine these installation effects.The model for roof-mounted sources takes account of diffraction at the corner of the train body or fairing,using a barrier model.For equipment mounted under the train,the acoustic propagation from the sides of the source is based on free-field Green’s functions.The bottom surfaces are assumed to radiate initially into a cavity under the train,which is modelled with a simple diffuse field approach.The sound emitted from the gaps at the side of the cavity is then assumed to propagate to the receivers according to free-field Green’s functions.Results show good agreement with a 2.5D boundary element model and with measurements.Modelling uncertainty and parametric uncertainty are evaluated.The largest variability occurs due to the height and impedance of the ground,especially for a low receiver.This leads to standard deviations of up to 4 dB at low frequencies.For the roof-mounted sources,uncertainty over the location of the corner used in the equivalent barrier model can also lead to large standard deviations. 展开更多

The Ministry of Land, Infrastructure and Transport of Korea introduced the ITS system performance evaluation about six and a half years ago. The main purpose is to make sure that accurate and reliable real-time traffic data are collected from the ITS system installed. There are three types of performance evaluations, which are Quality Certification Test, Pre-Delivery Test and Periodic Check in Operation. In this paper the accuracy levels of vehicle detectors commonly used in Korea are analyzed based on the results of quality certification tests conducted during 2008-2012. The test items consist of volume, speed and occupancy. The analysis shows that loop detectors have the best levels of accuracy in all three test items and their levels of accuracy have been steady. Video image detectors do not have so good levels of accuracy as loop detectors, but the levels of accuracy have improved as time passes. Radar detectors do not have good levels of accuracy. However, their levels of accuracy have improved as time passes. The last vehicle detectors, geomagnetism detectors have the worst accuracy in the occupancy item. 展开更多

Climate change threatens cocoa quality, raising concerns regarding sustainable premium cocoa production. Evaluating the effectiveness of certification standards is imperative to address this concern effectively. A multi-stage method was employed for a systematic review of 39 peer-reviewed articles to highlight the impacts of climate change on the biophysical environment of cocoa and its implications for adapting Geographical Indications (GIs). Additionally, a comprehensive review was conducted on climate-relevant standards of certificates in Ecuador, Indonesia, and Ghana. The findings of this study provide practical insights into possible difficulties that cocoa-producing countries may encounter in maintaining the distinctive flavours and quality trademarks of cocoa in the face of changing climate. Moreover, the findings emphasize the need for producer countries to prioritize viable adaptation and product differentiation strategies that meet sustainable marketing standards to protect GIs or place-based intellectual property. Furthermore, the findings indicate certificates require effective multi-level climate change management and environmental-social-governance principles that promote scientifically proven mitigation strategies, such as increasing soil organic carbon, zero deforestation, and reducing emissions while striving to leverage local adaptation policies to reduce location-specific vulnerability. Finally, certificates can accelerate the expansion, intensification, and redistribution of sustainable production for gains that outweigh the inconveniences caused by climate change. 展开更多

We explore the organizational, environmental, and economic effects of sustainable forest management (FM) certification by Smart- Wood (SW), one of the certification bodies accredited by the Forest Stewardship Council (FSC) to carry out certification in Japan. We closely investigated three enterprises: the Yusuhara Forest Owners' Cooperative, Yamanashi Prefectural Forest, and Ryujin-mura Forest Owners' Coopera- tive. Interviews with representatives of these entities provided crucial empirical information regarding the influence of certification on envi- ronmental assessment, rare-species protection, landscape-management planning, management objectives, and forest supervision. Attainment of FM status improved environmental awareness and engendered positive changes in assessing and managing forests and other natural resources but simultaneously imposed heavier economic costs. 展开更多

Enterprises and their products require corresponding international qualification when they participate in international market competition after China joined WTO. At present, the number of certified welding fabrication companies is still small. However, more and more enterprises are getting to realize the importance, and we have already had the following basic conditions: welding personnel qualification according to the international guidelines and rules, welding standards equivalent to ISO and EN standards, as well as full successful experiences of company certification gained through cooperation between China and Germany. So with additional industries’ support and government’s attention, company certification according to international rules will provide qualification guarantee for welding fabrication companies to participate in international market competition. 展开更多

GIS certification has been a contentious issue amongst geo-technology professionals for years. Many arguments have been advanced for it, the chief one being that certification is the only way through which a true GIS professional can be defined for the consumer public. There have been counter arguments, for example that certification will limit the widespread adoption of GIS technology, which is just a tool that anybody should be free to apply, or that it will only add another layer of regulation in a global political environment that favours increased de-regulation. The objective of this paper is to create greater awareness about GIS certification, which doesn’t exist yet in many countries, including some developed ones. Such increased awareness may encourage the standardization of GIS personnel qualifications, which could underpin a better, more dependable growth of the GIS industry, especially in the developing countries. Through analysis of key existing literature on the subject, plus the author’s own professional experiences, the paper explores the issues around GIS certification, looks at global trends on the issue and discusses the situation in the Kenyan GIS industry in respect of certification. The paper finds that there is a global move towards certification, and the relevant work of ISO has given the issue international attention. However, the paper also finds that the presence of a strong GIS professional association greatly assists in the development of a program for such certification, and that the lack of such an association makes it difficult to succeed. 展开更多

With the increasing proportion of renewable energy in the power market,the demands on government financial subsidies are gradually increasing.Thus,a joint green certificate-carbon emission right-electricity multi-market trading process is proposed to study the market-based strategy for renewable energy.Considering the commodity characteristics of green certificates and carbon emission rights,the dynamic cost models of green certificates and carbon rights are constructed based on the Rubinstein game and ladder pricing models.Furthermore,considering the irrational bidding behavior of energy suppliers in the actual electricity market,an evolutionary game based multi-market bidding optimization model is presented.Subsequently,it is solved using a composite differential evolutionary algorithm.Finally,the case study results reveal that the proposed model can increase profits and the consumption rate of renewable energy and reduce carbon emission. 展开更多

Forest certification has positive environmental spillovers.Considering environmental spillovers,this study ana‐lyzed the social welfare effects of forest certification using partial and general equilibrium methods.The re‐sults of the partial equilibrium analysis showed that social welfare in producing countries tended to increase under the market expansion of certified forest products.The general equilibrium analysis results indicated that,in autarky,or economic independence,the production amount of certified forest products could increase.If conventional forest products are imported and certified forest products are exported,then the level of utility in free trade condition is greater than that in autarky.If conventional forest products are exported and certi‐fied forest products are imported,then the price of imported products must be compared with the price of the autarky domestic market to determine the utility level of free trade and autarky.If the price of certified prod‐ucts is less than the price at the time of autarky,then the total utility level increases;otherwise,it decreases.The social welfare effect of forest certification can be increased through expanding the market demand of cer‐tified products and giving these products subsidies in production and price incentives in importing. 展开更多
