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.

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.

摘要: 人类驾驶与自主驾驶在对交通环境的理解方式上有着明显差别。首先,人主要通过视觉来理解交通场景,而机器感知需要融合多种异构的传感信息才能保证行车安全。其次,一个熟练的驾驶员可以轻松适应各种动态交通环境,但现有的机器感知系统却会经常输出有噪声的感知结果,而自主驾驶要求感知结果近乎100%准确。本文提出了一种用于无人车交通环境感知的视觉主导的多传感器融合计算框架,通过几何和语义约束融合来自相机、激光雷达(LIDAR)及地理信息系统(GIS)的信息,为无人车提供高精度的自主定位和准确鲁棒的障碍物感知,并进一步讨论了已成功集成到上述框架内的鲁棒的视觉算法,主要包括从训练数据收集、传感器数据处理、低级特征提取到障碍物识别和环境地图创建等多个层次的视觉算法。所提出的框架里已用于自主研发的无人车,并在各种真实城区环境中进行了长达八年的实地测试,实验结果验证了视觉主导的多传感融合感知框架的鲁棒性和高效性。

《环境科学与工程前沿(英文)》 2014年 第8卷 第3期   页码 316-328 doi: 10.1007/s11783-014-0625-5

摘要: Considering the significant roles of the policies in developing environmental finance, an overview is conducted on the environmental finance policies (EFPs) in China. This paper analyzed the definition, scope, evolution and main instruments of EFPs. The implementation progress of financial activities on each instrument are investigated respectively. Then the experiences learned from and failures discovered in the development of the EFPs are discussed well recommendations for further improvement of the EFPs and their implementation are provided. Our study found that the EFPs have been established in China after a four-phase evolution since the early 1980s. The policies have played a critical role in leading to a rapid development in environmental finance by involving more financial instruments to accomplish the objective-led environmental plans. Driven by the policies, the new green credit (GC), green security (GS), and green insurance (GI) instruments have been phased in as supplements to the conventional command and control approaches to improve the environmental governance of financial activities and pollution sources. However, the market mechanism of financial institution is limited due to their defensive and incapable performance on implementation some of EFP instruments. To further strengthen the effectiveness of EFPs in facilitating environmental management, recommendations are made mainly on the aspects including developing more specific policy guidelines, enhancing information sharing and disclosure, providing sufficient economic incentives, establishing environmental liabilities with financial activities, and involving issues related to climate change, and biodiversity and ecosystem service.

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。

摘要: An overview of the spatial and temporal variations of the environmental accidents in China in recent years was presented in this paper using available data. The results showed that the frequency of pollution accidents was significantly decreased, from 3462 in 1990 to 462 in 2007. The water and air pollution accidents were found to be the dominant types, accounting for more than 80% of the total accidents. Considering the classification of environmental accidents at 4 scales, the general environmental accident, i.e., the least serious type, was the most frequent event, taking up 58.98% of the total pollution accidents. In addition, the distribution of environmental accidents was generally in accordance with the industrial layout in the country during the past decade. It is very important to note that the extraordinarily severe environmental accidents showed an increasing trend in underdeveloped regions, which was caused by the transfer and the development of heavy polluted industry in these areas. As to the losses of environmental accidents, the casualties presented an obvious reduction tendency, while the direct economic loss per accident tended to climb up. Furthermore, some key factors that affect the spatial and temporal tendencies of environmental accidents in China were discussed and some suggestions were put forward, hoping to shed light on environmental risk management and emergency plans making associated with environmental accidents in China.

摘要: In this study, China’s current macro-environmental policies as well as their implementation and management tools are analyzed. By using the basic economic methodology, detailed studies are conducted focusing on the implementation effect of contemporary China’s typical environmental policy of the total pollutant discharge quantity control type, and also the two types of environmental management tools are compared from the perspective of implementation costs and policy uncertainty. By introduction of distributed management tools into the implementation of environmental policies, market-oriented means and the methods of economic analysis are introduced into environmental policy decision-making mechanisms, which could afford a new method for changing the current relatively low efficiency of environmental policy, solving the problem of “government failure” in environmental policy implementation, and providing a new way to make environmental policy system more flexible and more efficient. It is of great practical significance to solve China's current structural, complex and accumulative environmental problems.

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.

Hydrogel photocatalysts for efficient energy conversion and environmental treatment

《能源前沿(英文)》 2021年 第15卷 第3期   页码 577-595 doi: 10.1007/s11708-021-0756-x

摘要: Photocatalysts have attracted great research interest owing to their excellent properties and potential for simultaneously addressing challenges related to energy needs and environmental pollution. Photocatalytic particles need to be in contact with their respective media to exhibit efficient photocatalytic performances. However, it is difficult to separate nanometer-sized photocatalytic materials from reaction media later, which may lead to secondary pollution and a poor recycling performance. Hydrogel photocatalysts with a three-dimensional (3D) network structures are promising support materials for photocatalysts based on features such as high specific surface areas and adsorption capacities and good environmental compatibility. In this review, hydrogel photocatalysts are classified into two different categories depending on their elemental composition and recent progresses in the methods for preparing hydrogel photocatalysts are summarized. Moreover, current applications of hydrogel photocatalysts in energy conversion and environmental remediation are reviewed. Furthermore, a comprehensive outlook and highlight future challenges in the development of hydrogel photocatalysts are presented.
