基于突变理论的建筑工人不安全行为研究

为有效减少建筑工人的不安全行为,在分析不安全行为各影响因素的基础上,结合不安全行为形成机理图,从突变理论的全新视角构建建筑工人不安全行为尖点突变模型,验证了该模型诠释建筑工人不安全行为形成规律的合理性,并利用该模型对建筑工人不安全行为形成过程进行分析,解释建筑工人在个体心理和准环境因素交互作用下行为的渐变-突变过程。最后提出了建筑工人不安全行为的防御措施、靶向干预点和补救策略。     

Towards sustainable consumption: Predicting the impact of social‐psychological factors on energy conservation intentions in Northern Cyprus

The incessant demand and consumption of energy services among individuals’ is increasing throughout the world. Individuals’ electricity consumption in Northern Cyprus has risen considerably. However, the demand for electrical energy services on the island is heavily reliant on imported fossil fuels. Burning fossil fuels has adverse effects on its environment. Therefore, sustainable energy consumption is required and individuals are targeted for energy conservation to reduce electricity consumption. Against this background, using the Structural Equation Modeling approach, this research incorporates social‐psychological factors; personal norms, positive and negative emotions into the theory of planned behaviour (TPB) model to assess the relationships among the variables, explain their impact on consumers’ electricity conservation intentions and enhance the explanatory power of the model. Data was conveniently obtained from a quantitative sample of 400 electricity consumers. The results indicate that negative emotions have the strongest significant influence on intentions, but personal norms have the least effect on intentions to save electricity. Furthermore, the study revealed that our expanded TPB model can provide improved explanatory power more than the original TPB. Policy implications, limitations and future research are discussed.     

基于D-S证据理论的“丝绸之路旅游带”5A景区区位优势度测评

景区发展与其区位条件密切相关,处于优势区位的景区更容易获得优先快速发展。以“丝绸之路旅游带”为例,综合考虑资源、市场、交通及服务四大区位因子,将其视为证据,引入D-S证据理论对景区区位优势进行测度,以I~V级表征区位由优到劣的状态,最后对景区区位与旅游发展核心区进行对比。结果显示：（1）区位优势等级区域差异化显著,总体呈现由东南至西北逐级递减的空间分布规律,自I至V级,重心逐步向西北方向偏移。（2）各区位因子分布存在差异性,东南地区景区资源区位优于西北地区;市场区位地带间差异最为明显,存在“长尾”特征及陕西“一省独大”现象;交通区位内在差异性与区位优势相仿;服务区位已不再是制约景区区位的主要因子,但就单个省份来看,“核心—边缘”结构较为明显。（3）与景区旅游发展对比来看,二者具有明显的空间关联性,但仍存在一定程度的空间错位现象。     

Theoretical study on the formation mechanism of polychlorinated dibenzothiophenes/thianthrenes from 2-chlorothiophenol molecules

Homogeneous formation of polychlorinated dibenzothiophenes/thianthrenes(PCDT/TAs),sulfurated compounds analogous to polychlorinated dibenzo-p-dioxin/dibenzofurans(PCDD/Fs), has been well-documented to occur via radical–radical coupling reactions from chlorinated thiophenol precursors. However, the current understanding of the formation mechanism of PCDT/TAs is exclusively limited to the inherent point of view that chlorothiophenoxy radicals act as the only required intermediates for PCDT/TAs. This study investigates reaction pathways for the formation of PCDT/TAs involving two new types of radical species, i.e., substituted phenyl radicals and substituted thiophenoxyl diradicals. Taking 2-chlorothiophenol(2-CTP) as a model compound for chlorothiophenols,we found that apart from the mostly discussed chlorothiophenoxy radicals, substituted phenyl radicals and substituted thiophenoxyl diradicals could also be readily formed via the reaction of 2-CTP with H radicals. Furthermore, direct self-and cross-coupling of these radicals can result in the formation of PCDT/TAs, including 1-monochlorothianthrene(1-MCTA), 1,6-dichlorothianthrene(1,6-DCTA), 4,6-dichlorodibenzothiophene(4,6-DCDT)and 1,6-dichlorodibenzothiophene(1,6-DCDT). The pathways proposed in this work are proven to be both thermodynamically and kinetically favorable. Particularly, comparisons were made between the formation mechanisms of sulfurated and oxygenated dioxin systems from an energetic point view, showing that replacing oxygen with sulfur atoms greatly reduces the activation barriers of the rate-controlling steps involved in the PCDT/TA formation processes compared with those involved for PCDD/Fs. The calculated results in this work may improve our understanding of the formation mechanism of PCDT/TAs from chlorothiophenol precursors and should be informative to environmental scientists.

安全与危险纠缠理论创建及其研究

针对安全概念不统一,安全科学与技术发展相对滞后,重特大安全事故频发等问题,通过借鉴量子纠缠理论,提出了安全与危险纠缠理论学说。建立了安全与危险纠缠理论模型,阐述了其纠缠机制,明确了一个系统中的安全与危险在不同时段内存在的方式和状态:通常人们所认知的安全或危险均是系统在过去时段内以“一显一隐”的方式塌缩成确定的状态,而在现在与未来时段,它们分别是以“显性”、“隐性”的方式纠缠为不确定的状态;若该系统的“安全与危险纠缠”状态向安全方向塌缩时,系统则表现为安全,若向危险转化时,则系统表现为事故。同时,分析了“安全与危险纠缠”理论建立的对安全科学及安全生产实际意义与理论价值,及其未来展望和存在问题。
