可持续发展战略的环境保护行动

从可持续发展论释义,以及以污染现实反证,提出环境是可持续发展的基础,保护环境就是保护人类社会赖以生存和发展的自然资源,自然资源是发展的根本条件的论点,进而提出环境保护工作的二项基本任务。依此提出可持续发展战略的环境保护行动框架意见。     

我国标准气体应用于涉VOCs重点行业监测管理中的不足及建议

随着我国对VOCs监测控制的持续推进,VOCs标准气体的配套应用及其管理思路也面临着新要求和挑战。本文通过梳理我国VOCs类标准气体对涉VOCs企业污染物监测和管理支撑的现状,指出了VOCs监测管理中对标准气体的应用要求尚待细化、已有VOCs标准气体应用不够充分、VOCs标准气体对排放标准实施的精准支撑作用不足等问题。在探究现状与问题的基础上,提出进一步细化VOCs排放监测对标准气体应用要求、加强企业自行监测中VOCs标准气体的应用指导、加强短缺标准气体的研制与应用的建议。     

安全信息学视域下安全舆情演化及引导策略研究*

为正确引导和控制负面安全舆情,基于安全信息学与舆情理论,利用事故树分析方法研究安全舆情演化过程,计算负面安全舆情最小割集、最小径集和结构重要度,提出安全舆情引导方法。结果表明:利用最小割集得到负面安全舆情产生原因组合,利用最小径集得到避免负面安全舆情产生最低限度事件组合,通过结构重要度得到系统改进重点及优化顺序;在事故树中增加安全舆情审核和引导组织、安全事件亲自确认、专业意见领袖3个最小径集,以期减少负面安全舆情,促进公共安全。

Decision support for sustainable manufacturing using decision guidance query language

Sustainability has become a very significant research topic as it impacts many different manufacturing industries. Therefore, the technologies for monitoring, analysing, evaluating and optimising the sustainability performance of manufacturing processes and systems are very critical for decision makers on the shop floor. This paper introduces a decision guidance management system that provides actionable recommendations through quantitative analysis of the sustainability measures of manufacturing processes and systems based on life cycle assessment. The system determines decision preferences through dynamically collected data and decision makers' responses, taking into account the prevailing constraints. Optimal decisions can be derived using mathematical and constraint programming. By using decision guidance query language, this methodology allows users to make optimal decisions without an extensive mathematical or operations research background. Knowledge of relational databases is sufficient for a user to formulate the optimisation problem and obtain optimal solutions. The methodology is demonstrated with a machining operation case study, in which a list of sustainability metrics are identified and sustainability modelling methods are proposed. Important sustainable machining performance measures are optimised, resulting in actionable recommendations.     

Person–organization and person–supervisor fits: Employee commitments in a Chinese context

The present study simultaneously examined people's perceptions of person–organization (PO) and person–supervisor (PS) fit and related these perceptions to employees' commitments. Three‐hundred‐and‐sixty employee–supervisor dyads from Taiwanese organizations reported about their PO fit and PS fit perceptions. In addition, supervisors reported about their perceptions of fit and guanxi with each of their employees. Results indicated that PO and PS fit perceptions both had an independent and additive relationship with organizational commitment. The link between employee PS fit perceptions and organizational commitment was mediated by commitment to the supervisor. Both employee and supervisor fit perceptions contributed to commitment to the supervisor through their influence on the quality of the leader‐member exchange (LMX). Guanxi could not explain additional variance in LMX and supervisor commitment. Implications for theory and practices regarding person–environment fit, commitment, and LMX are discussed. The study findings offered suggestions for a new Theory of Multiple Fits. Copyright © 2010 John Wiley & Sons, Ltd.     

复杂建筑空间人员应急疏散的无人机引导模型研究*

为提升紧急情况下复杂建筑空间中应急疏散引导的疏散效率,采用仿真模拟方法,提出1套可适用于复杂建筑空间人员应急疏散的无人机引导模型,该模型通过改进传统算法和构建新方法,实现无人机空间遍历移动规则寻优、无人机引导路径寻优以及基于“障碍物空间场域”建筑空间区域划分。研究结果表明:相较于没有无人机引导,采用单无人机和多无人机协同引导疏散,可大幅缩短整体疏散时间,有效减少疏散路径当量长度,提高疏散效率并保证路径安全,为无人机在应急救援和疏散的应用提供新思路。

城市空气质量监测网络评估方法

通过研究借鉴多个国家/城市的研究实践,提出了城市空气治理监测网络（UAAMNA）评估管理的方法,包括评估思路与流程,评估关键指标,针对不同污染物的评估方法等.以沈阳市及周边6个城市共46个国控监测站点的监测网络为背景,基于2013~2018年日尺度空气质量数据,考虑监测成本,对沈阳市PM_2.5监测网络进行评估,结果表明,沈河区增加1个最高浓度站点,大东区增加1个高人口密度区站点,皇姑区增加1个跨界传输点;在沈阳-铁岭,沈阳-本溪,沈阳-辽阳方向增设跨区域站点.未来建立空气质量监测网络定期评估制度、加强跨区域边界站点布设、实施区分监测点位类型评估、区分污染物类型评估是UAAMN的发展方向.     

Time‐based differences in the effects of positive and negative affectivity on perceived supervisor support and organizational commitment among newcomers

Building on the broaden‐and‐build theory and research on the negativity bias, this study examines how trait affectivity, as a stable predisposition predicting the pattern of emotional responding, shapes newcomers' perceptions of supervisor support and experience of organizational commitment. Using latent growth modeling and data collected at four points in time from newcomers (N = 158), we found the initial level of perceived supervisor support to mediate a negative relationship between negative affectivity and the level of commitment. Moreover, although newcomers experienced a general decrease in perceived supervisor support and a related decrease in commitment, those with high positive affectivity experienced a weaker decrease in perceived supervisor support, which led to a weaker decrease in commitment. Incidentally, positive affectivity was also positively related to the initial level of commitment. Two post hoc studies indicated that positive and negative affectivity exerted their effects controlling for state affect and replicated the relationship between change in perceived support and commitment. We discuss how these findings inform our understanding of trait affectivity's influence on newcomers' work attitudes.
