Perception of people for the risk of Tianwan nuclear power plant

Lei HUANG, Jun BI, Bing ZHANG, Fengying LI, Changsheng QU,

《环境科学与工程前沿（英文）》 2010年 第4卷 第1期   页码 73-81 doi: 10.1007/s11783-009-0151-z

摘要： A questionnaire survey of residents’ risk perceptions related to Taiwan nuclear power plant in China was carried out to explore the determining factors that affect individual risk perception. This study proposed to pursue a more comprehensive understanding of factors that affected individual risk perception to nuclear power plants. Covariance structure analysis was conducted using risk perceptions of nuclear power as dependent variable and including interest and knowledge levels of nuclear power, acceptability, benefit perception, trust in nuclear power operation, and trust in government as independent variables. The use of the hypothesis of Elaboration likelihood model (ELM) was also proposed. The results showed that persons with higher levels of interest and knowledge of nuclear power had their own perceptions of risk closely associated with acceptability and potential benefits of nuclear power. In contrast, persons with no interest in and knowledge of nuclear power would have risk perceptions related to their trust in nuclear operation and the government, which partially supported the ELM hypothesis. All these results indicated that the government in China plays an important role in rational risk perceptions, and well-designed communication of risks will help the public to be involved in risk management and improve people’s rational acceptance of risk.

Understanding Farmers’ Perceptions and Risk Responses to Climate Change in China

Yang-jie Wang,Xiao-hong Chen

《工程管理前沿（英文）》 2015年 第2卷 第3期   页码 201-210 doi: 10.15302/J-FEM-2015050

摘要： Agriculture is likely to bear the brunt of the impacts of climate change. The extent to which these impacts are felt depends in large part on the extent of adaptation in response to climate change. The overall aim of this paper is to attempt to identify farmers’ knowledge, perceptions and risk responses towards climate change (or potential change). In order to achieve this goal, several specific objectives are pursued. First, the paper investigates whether or not farmers have perceived the long-term climate change and extreme weather events. Second, the paper describes how farmers respond to climate change and tries to assess the determinants of their adaptation. Based on data collected from a survey among farm households in three provinces in rural China, the findings demonstrate that farmers are aware of climate variability and identify the rising temperature, decreasing precipitation and the increasing frequency of drought. Only about 25% of farmers are willing to adjust their farming structures as a risk reaction. Household size, wealth, farm size, and the number of plots are found to be important factors that influence farmer adaptive capacity. Implications for policymaking on agriculture and adaptation to climate change will be to focus on providing farmers with information about the climate in time and facilitating enhancement of their adaptive capacity.

The influencing factors of the WTP for the risk reduction of chemical industry accidents in China

Lei HUANG, Zhijuan SHAO, Weiliang BAO, Bailing DUAN, Jun BI, Zengwei YUAN

《环境科学与工程前沿（英文）》 2012年 第6卷 第6期   页码 860-868 doi: 10.1007/s11783-012-0467-y

摘要： To explore the factors that influence respondents’ willingness to pay (WTP) for the risk reduction of chemical industry accidents, a questionnaire survey combined with contingent valuation and psychometric paradigm methods were conducted in the city of Yancheng, Jiangsu Province, China. Both traditional socioeconomic variables and perceived characteristics of the hazards were considered in this study, and a Tobit model was used to find the factors influencing WTP under three risk reduction scenarios. The results showed that three demographic characteristics, , , and , significantly affected the WTP for chemical risk reduction. In addition, three extracted public risk perception factors, , , and , also strongly affected the WTP. The mean WTP value increased as the magnitude of the risk reduction increased. The number of factors influencing the WTP decreased as the reduction level improved, and only the factor had a significant influence on the WTP for a higher level (80%) of risk reduction. The cost for chemical safety management of Yancheng was calculated, and the optimized risk reduction level was determined. These findings can assist governments and policy makers to formulate suitable strategies for risk control, to reach target groups of people to develop effective communication, and to provide specific references for the best investment for the security of local residents.

Public perception of environmental issues across socioeconomic characteristics: A survey study in Wujin

Jun BI, Yongliang ZHANG, Bing ZHANG,

《环境科学与工程前沿（英文）》 2010年 第4卷 第3期   页码 361-372 doi: 10.1007/s11783-010-0017-4

摘要： In developing countries, there is controversy over the correct perception regarding environmental and developmental issues. Few studies have examined the perception of low-income nationals in regards to social and environmental issues. This paper looks at the relationship between socio-demographic factors and the groups’ perceived priority regarding environmental and social issues in Wujin County. The results indicated that most residents, specifically the young, government employed and the urban community consider environmental issues to be serious, especially in relation to air pollution and water pollution. Furthermore, many residents feel it is important to rank environmental problems that are related to other social and economic issues, and that environmental protection must be set as a priority in Wujin County. Compared to social issues, environmental concern was greater among the young, government employed, and the urban community, because of their higher education and affluence. In addition, 66.2% of residents consider environmental protection to be more important than economic development. Thus, environmental protection must be set as a high priority in Wujin County, in order to face the many social and environmental challenges inherent in development.

Understanding and addressing the environmental risk of microplastics

《环境科学与工程前沿（英文）》 2023年 第17卷 第1期 doi: 10.1007/s11783-023-1612-5

摘要：

Over the past decades, the plastic production has been dramatically increased. Indeed, a category of small plastic particles mainly with the shapes of fragments, fibers, or spheres, called microplastics (particles smaller than 5 mm) and nanoplastics (particles smaller than 1 μm) have attracted particular attention. Because of its wide distribution in the environment and potential adverse effects to animal and human, microplastic pollution has been reported as a serious environment problem receiving increased attention in recent years. As one of the commonly detected emerging contaminants in the environment, recent evidence indicates that the concentration of microplastics show an increasing trend, for the reason that up to 12.7 million metric tons of plastic litter is released into aquatic environment from land-based sources each year. Furthermore, microplastic exposure levels of model organisms in laboratory studies are usually several orders of magnitude higher than those found in environment, and the microplastics exposure conditions are also different with those observed in the environment. Additionally, the detection of microplastics in feces indicates that they can be excreted out of the bodies of animal and human. Hence, great uncertainties might exist in microplastics exposure and health risk assessment based on current studies, which might be exaggerated. Policies reduce microplastic emission sources and hence minimize their environmental risks are determined. To promote the above policies, we must first overcome the technical obstacles of detecting microplastics in various samples.

《工程管理前沿（英文）》 2015年 第2卷 第3期   页码 311-319 doi: 10.15302/J-FEM-2015045

摘要： Following rapid infrastructure development and industrialization, the problems of water pollution and water shortage have become more severe. Whether there is safe drinking water in cities has attracted wide attention. The ecological risk management of drinking water project is an important means of ensuring the safety of a drinking water source. Based on ecological risk assessment and management theories, this paper establishes an ecological risk management model and assessment system with the aim of providing theoretical guidance and scientific basis for formulating a policy on the safety and protection of drinking water sources in a city. Kunming is one of the cities plagued by severe water shortage in China. Its ecological risk management of drinking water has attracted the attention of both the local government and the public. Using Kunming as the case study, this paper conducts a comparative analysis and assessment on three major reservoirs that face ecological risks. It highlights the existing problems and gives helpful suggestions.

针对水下作业的新型机器人视觉感知框架 Research Article

鲁岳1,陈星宇2,吴正兴1,喻俊志1,3,文力4

《信息与电子工程前沿（英文）》 2022年 第23卷 第11期   页码 1602-1619 doi: 10.1631/FITEE.2100366

摘要：

水下机器人操作通常需要视觉感知（如目标检测和跟踪），但水下场景视觉质量较差，且代表一种特殊分布，会影响视觉感知的准确性。同时，检测的连续性和稳定性对机器人感知也很重要，但常用的基于静态精度的评估（即平均精度（average precision））不足以反映检测器的时序性能。针对这两个问题，本文提出一种新型机器人视觉感知框架。首先，研究不同质量的数据分布与视觉恢复在检测性能上的关系。结果表明虽然分布质量对分布内检测精度几乎没有影响，但是视觉恢复可以通过缓解分布漂移，从而有益于真实海洋场景的检测。此外，提出基于目标轨迹的检测连续性和稳定性的非参考评估方法，以及一种在线轨迹优化（online tracklet refinement，OTR）来提高检测器的时间性能。最后，结合视觉恢复，建立精确稳定的水下机器人视觉感知框架。为了将视频目标检测（video object detection，VID）方法扩展到单目标跟踪任务，提出小交并比抑制（small-overlap suppression，SOS）方法，实现目标检测和目标跟踪之间的灵活切换。基于ImageNet VID数据集和真实环境下的机器人任务进行了大量实验，实验结果验证了所作分析的正确性及所提方法的优越性。代码公开在https://github.com/yrqs/VisPerception。

A novel task-oriented framework for dual-arm robotic assembly task

《机械工程前沿（英文）》 2021年 第16卷 第3期   页码 528-545 doi: 10.1007/s11465-021-0638-2

摘要： In industrial manufacturing, the deployment of dual-arm robots in assembly tasks has become a trend. However, making the dual-arm robots more intelligent in such applications is still an open, challenging issue. This paper proposes a novel framework that combines task-oriented motion planning with visual perception to facilitate robot deployment from perception to execution and finish assembly problems by using dual-arm robots. In this framework, visual perception is first employed to track the effects of the robot behaviors and observe states of the workpieces, where the performance of tasks can be abstracted as a high-level state for intelligent reasoning. The assembly task and manipulation sequences can be obtained by analyzing and reasoning the state transition trajectory of the environment as well as the workpieces. Next, the corresponding assembly manipulation can be generated and parameterized according to the differences between adjacent states by combining with the prebuilt knowledge of the scenarios. Experiments are set up with a dual-arm robotic system (ABB YuMi and an RGB-D camera) to validate the proposed framework. Experimental results demonstrate the effectiveness of the proposed framework and the promising value of its practical application.
