建筑安全事故防范认知与主体身份特征关系诊断研究

为进一步研究建筑安全主体的身份特征对建筑安全事故防范认知的影响,通过分析现有文献,对建筑安全主体身份特征、建筑安全管理认知、建筑安全技术措施认知和建筑安全事故防范认知4个因素分别进行探讨,并提出其相互之间的关系假设。基于结构方程模型(SEM)方法,构建由4个因子16个观测变量组成的指标体系。采用LISREL8.53软件,验证因子及观测变量之间的关系。个案研究结果表明,主体身份特征对建筑安全管理认知、安全技术措施认知和建筑安全事故防范认知具有较强的社会属性效应,主体身份特征通过建筑安全管理认知、安全技术措施认知对建筑安全事故防范认知的正效应也比较明显。重塑建筑安全主体社会属性、加强安全管理和技术措施教育,均能有效提高建筑安全事故防范认知。     

太湖流域分散农村居民对生活垃圾的产生和处理认知分析

本文通过问卷调查的方式考察了太湖流域分散农村居民对政府免费实施"村收集、乡转运、县处理"的收集清运垃圾模式和未来生活垃圾处置收费的认可度,获得了太湖地区分散农村居民对生活垃圾处置现状的认知度,结果表明:农村居民对生活垃圾收费制度的认可程度低,对有害垃圾的处置缺乏必要的认识;被调查者受教育程度与垃圾分类(P0.01)、危险废物分离(P0.01)和垃圾危害的认知程度(P0.05)呈显著正相关关系;垃圾付费选项中,被调查者不愿意支付费用的占53.2%,仅有26.2%的被调查者愿意支出1~3元/月;对现有的政府免费收集清运垃圾模式认可程度高达94%以上。该研究结果对促进太湖流域农村生活垃圾的资源化与减量化管理具有重要的战略意义。     

A novel driver hazard perception sensitivity model based on drivers’ characteristics: A simulator study

Objective: Considering the high annual number of fatal driving accidents in Iran, any approach for reducing the number or severity of driving accidents is a positive step toward decreasing accident-related losses. Accidents can often be avoided by a timely reaction of the driver. One of the steps before reacting to a hazard is perception. Some driver characteristics may affect road hazard perception. In this research, it was assumed that various driver characteristics, including demographic characteristics and cognitive characteristics, have an impact on driver perception.

Methods: The driving simulator used in this research provides various scenarios; for example, passing a pedestrian or animal across the road or placing fixed objects in a 2-lane separated rural road for 2 groups of experienced and inexperienced drivers under day and night lighting conditions. The go/no-go test was carried out in order to assess drivers’ attention to driving tasks and inhibitory control. A structural equation model (SEM) was used to estimate the relation between driver characteristics and sensitivity to road hazard perception. A new hazard perception index was proposed based on the time intervals in the hazard vulnerability.

Results: The results show that the most effective variables in the analysis of sensitivity to hazard perception are driving experience (in kilometers) during the last 3 years and road lighting conditions. Moreover, hazard perception sensitivity was improved by better inhibitory control, selective attention, and decision making, more carefulness, the average amount of daily sleep, and marital status.

Conclusion: The results of this research may be useful in educating and advertising programs. It also could enhance sensitivity to perception of hazards such as pedestrians, animals, and fixed obstacles among young and novice drivers.

省级“双评价”的理论思考与实践方案——以浙江省为例

资源环境承载能力与国土空间开发适宜性评价（“双评价”）在国土空间规划体系中发挥着重要的基础性作用,是空间决策科学性和空间治理有效性的基本保障。从省级国土空间规划的定位出发,剖析省级国土空间规划对“双评价”科学支撑和简单适用的基本要求,总结当前省级“双评价”面临理论与实践的挑战。在此基础上,构建了一套“三维内涵—一对关系—两种尺度—四个层面”的省级“双评价”方案,深入挖掘资源环境承载的能力、压力、潜力三维内涵,立足于承载力与适宜性之间的逻辑联系,以浙江省为案例,从县级行政区和栅格单元两种尺度开展了“双评价”实践,并从优势短板识别、要素空间统筹、开发时序安排及空间格局优化四个层面支撑省级国土空间规划的编制。旨在为省级“双评价”提供一种可行、科学、实用的评价框架,为国土空间规划中布局优化、结构调整、指标分解等实践提供支撑。     

An empirical research on the determinants of Chinese college students’ carbon label cognition and interpersonal communication willingness

Carbon labels are innovative medium and tools for climate change communication and low-carbon marketing. This study aims at examining how college students are aware of low-carbon and carbon labels, whether they are more willing to communicate low-carbon ideas, and also the determinants affecting their interpersonal communication of carbon labels. The multiple regression analysis shows that Chinese college students’ willingness of interpersonal communication of carbon labels are significantly influenced by their awareness of climate change crisis, the perceived value of carbon labels, the consideration of product environmental attributes, the preferences of carbon labels, the household background, and their educational background. In response to these factors, this paper proposes, in a public perspective, the strategies to enhance the dissemination of carbon labels.     

Public support for carrot,stick, and no-government water quality policies

Public support for environmental policy provides an important foundation for democratic governance. Numerous policy innovations may improve nonpoint source pollution, but little research has examined which types of individuals are likely to support various runoff reduction policies. We conducted a household mail survey of 1136 residents in southern Wisconsin. In general, residents were more likely to support water quality policies if they were communitarians, egalitarians, concerned about water pollution, and perceived water quality as poor. The majority of respondents somewhat to strongly supported all of the seven proposed water quality policies, but opposed relying on voluntary action without government involvement on farms. Residents had higher support for incentives and market-based approaches (carrot policies) than regulation and taxes (stick policies). A more complicated pattern emerged in within-subject comparisons of residents’ views of carrot and stick approaches. Stick approaches polarized respondents by decreasing support among people with individualistic worldviews, while slightly increasing support among people with communitarian worldviews. Residents with an agricultural occupation were more likely to support voluntary, non-governmental approaches for reducing agricultural runoff, and were also more likely to support regulation for reducing urban lawn runoff. This research highlights the dominant role of cultural worldviews and the secondary roles of water pollution concern, perceived water quality, and self-interest in explaining support for diverse policies to reduce nonpoint source pollution.
