室内空气品质评价方法研究进展

介绍了室内空气品质评价的定义、评价的标准和几种现行的评价方法.通过对这几种方法进行系统地介绍,比较这些方法在室内空气品质评价时的优劣,对其中的几种方法提出了改进意见,为进一步研究室内空气评价方法指明了方向.     

综合福利视角下中国生态文明建设绩效评价及国际比较

基于强可持续研究范式,以生态经济学和可持续发展理论为基础,运用两阶段网络Super-EBM模型进行绩效测算和评价,打开生态福利转化过程的“黑箱”,基于综合福利视角将生态文明建设绩效进一步分解为生态经济效率和经济福利效率,实证研究部分选取2006-2015年的时间序列数据对中国“十一五”和“十二五”期间的生态文明建设绩效水平进行纵向分析,与此同时,选取42个国家2014年的截面数据进行横向的国际对比研究。研究表明：（1）“十一五”到“十二五”期间,中国生态文明建设绩效（0.986）整体水平一般,均未实现DEA有效,但“十二五”期间已呈现出逐年改善的利好趋势。国际比较层面,瑞士（1.647）、印度尼西亚（1.365）、爱尔兰（1.039）依次排名前三位,中国（0.297）排名相对靠后,位列倒数第二。各国之间差异较大,总体上呈现出“OECD国家（0.677）最高、G20国家（0.611）次之、金砖国家（0.417）最低”的态势。（2）从分阶段效率来看,无论是纵向分析还是横向对比,均发现第一阶段的生态经济效率明显低于第二阶段的经济福利效率,生态经济效率偏低是导致生态文明建设绩效总体水平偏低的主要原因。（3）与传统的单阶段、径向或非径向DEA模型相比,两阶段网络Super-EBM模型综合考虑了径向和松弛变量问题,测算出来的效率值更为精确,能够更为客观地反映现实。同时,对于其他领域涉及两阶段或多阶段生产系统的效率或绩效评估具有较好的借鉴价值。最后,根据上述结论提出相应的政策建议。     

县级城市人居环境主客观指标体系与评价模型对比研究

本文对人居环境相关研究进行了阐述,并就城市人居环境指标体系与评价模型进行了分析研究。提出了人居环境质量主客观评价结合模型,其中指标体系包括四个一级指标和18个单项指标,并依据我国黄河三角洲高效经济区内14个县级城市2007年的调查统计资料,对人居环境客观建设水平和居民满意度进行了对比评价。运用因子分析法处理指标数据,问卷调查的方法进行满意度评价。评价结果科学可行,并揭示出影响县级城市人居环境的根本因素。     

电气伤亡事故的主客体场景指标设计及统计规律

为合理预防控制电气伤亡事故的发生提供依据,通过检索查阅国内外相关文献和政府网站公布的电气伤亡事故和案例情况描述,选取105起典型电气伤亡事故案例进行统计与分析;针对电气伤亡事故涉及的主客体场景要素,对其进行筛选、分类、排序及指标设计,形成系统的电气伤亡事故指标体系;结合现实情况对统计结果进行原因分析,根据统计结果,得到电气伤亡事故发生的一般规律,据此提出安全管理中需要关注与重视之处,以此来预防电气伤亡事故的发生。     

Environment and Personal Well-being in Urban China

The aim of this study is to examine the relationship between environment and personal well-being using a sample of 562 urban employees from three cities in Liaoning province in the People’s Republic of China.In contrast to previous studies,this study controlled positive affectivity (PA),negative affectivity (NA),job satisfaction and Big Five personality traits.In addition,the research variables of personal well-being index (PWI),positive affectivity,negative affectivity,job satisfaction,Big Five,and environmental satisfaction are measured with multi-item scales.The research finds that environmental satisfaction is positively related to personal well-being,suggesting that improvement of the natural surroundings in the cities can improve people’s well-being.     

SOCIAL WELL-BEING AND WATER RESOURCES PLANNING1

ABSTRACT: For many years, Federal water resources projects have been subjected to benefit-cost analysis to establish their economic feasibility. Several years ago social well-being was added as a consideration. This paper discusses the state-of-the-art in analyzing and evaluating aspects of social well-being. It stresses current short-falls and advocates a direction for further efforts.

自吸过滤式呼吸器对人体主观舒适度的影响

测定了在中等（100W）和高等（155W）劳动强度下，8名受试者佩戴5种自吸过滤式呼吸器（呼吸阻力及死腔不同）从事踏车运动时的主观舒适度。结果表明：随着呼吸负荷增大，受试者的主观不适度显著增强；在中等运动负荷条件下，高温环境中人员对呼吸负荷主观不适度的反应更加明显；在高运动负荷条件下，常温环境人员对呼吸负荷主观不适度的反应更加明显。     

The Subjective Rating Scales for Measurement of Mental Workload—Thurstonian Scaling

Subjective rating scales for measuring work demands and individual capabilities to cope with work requirements were developed using the Thurstonian procedure. The scales measure six dimensions of mental workload: mental difficulties, feeling of responsibility, awareness of risk, interpersonal conflicts, monotony, and time pressure. Individual scale results make it possible to assess the level of mental workload understood as a relation between the subjective rating of work demands and individual capabilities in each of the six dimensions. Two versions of scales were prepared: classic and modified ones. To assess the level of reliability of the particular scales, 481 participants were examined twice at a 1-month interval. A procedure to prepare scales for the measurement of other dimensions of mental workload is also presented.     

Re-emphasizing sustainable development — The concept of ‘Evolutionability’ On living chances, equity, and good heritage

The principle of sustainable development is now 15-year-old. There are a lot of definitions and models for its explanation — ranging from triangles and prisms to eggs — but still its sense is diffuse. Moreover, important aspects like equity are not sufficiently taken into account.The following article takes a critical look on sustainable development. It shows logical, systemic, philosophic and ethic reasons for the re-development of substantial parts of the principle of sustainability. Based on the proposed Principle of Good Heritage it provides a rough outline of a future Concept of Evolutionability, comprising a first tentative for a definition of evolutionable development, aiming at achieving a more appropriate and more workable mainstream view of sustainability.Readers should send their comments on this paper to: BhaskarNath@aol.com within 3 months of publication of this issue.
