我国再生铅行业的现状、问题和发展对策

我国汽车和电动车保有量的增长,孕育着废铅蓄电池回收和再生铅行业的发展和壮大,也使原生铅行业开始积极回收利用废铅蓄电池。废铅蓄电池属于危险废物,给生态环境和人体健康带来了很大的风险隐患。由于再生铅行业的政策、标准和管理细则不完善,再生铅企业的工艺设备和管理落后,导致我国铅中毒事件时常发生。概述了我国再生铅行业目前的发展状况,详细介绍了以铅膏等含铅废物为原料,通过还原熔炼、火法精炼(或电解精炼)等工序生产再生铅的过程;提出了我国再生铅行业存在的问题,并给出了相应对策。     

The problem with [in] management theory

Theory is essential to everything that we do as people studying and practicing industrial/organizational psychology and organizational behavior. But, I think that our field has lost its way recently and become enamored by shiny objects and interesting puzzles. Advancing management theory seems to have become an end state in and of itself. We seemed to be far more concerned with the entertainment value of theories than we are with their scientific rigor or real‐world value. Top journals in our field are mandating that all articles must make a theoretical contribution, and theoretical contributions are being gauged primarily in terms of how innovative, counter‐intuitive, surprising, and interesting they may be. I advocate for a more balanced approach, and in particular, for greater use of abductive inference. I argue that if you start with a real‐world challenge and draw from existing theory, and then develop new theory to understand and change things, you are also making a theoretical contribution. Whether or not we are guided by theory is not really at issue—at issue is how well developed are our theories, how accurate are they, and do they help us to improve organizational life for everyone involved?     

居住建筑节能设计中的问题与优化策略研究

今天,全球能源在日益减少,人们生活提高又需要增加居住面积,这势必造成能源的消耗.因此,建筑节能已经成为全球范围内都非常关注的一项问题.为了提高居住建筑节能,结合实际需要,针对居住建筑节能的必要性的设计要求展开阐述,同时从规划节能设计、单体节能设计以及节能构造设计这三个不同的角度来着手分析,以期能够在有限的条件下将居住建筑的环保性、功能性以及艺术性更加完美的结合到一起,促进低成本、高效率的节能型居住建筑建设目标早日实现.     

生态文明背景下物流业低碳化发展实现路径研究

物流业为碳排放量较大的行业,也是国家重点鼓励和支持的产业,实现其低碳化有利于增强行业竞争力、缓解环境问题、推动社会经济生态低碳化发展.物流业面对低碳化发展的机遇与挑战,应正视行业低碳化发展在政策和体制上存在的问题,同时需要政府健全低碳物流激励约束机制、完善物流相关基础设施;企业要有效实现共同配送和联合运输,积极推进低碳物流技术的研发与推广,完善物流信息系统,优化物流节点;社会公众形成低碳意识,支持低碳产品.     

论环境教育对全球环境问题的响应

目前,环境问题日趋突出,成为全球关注的重点。这已不是一个国家、一个政府、一个研究所所能解决的事情,需要全世界的共同努力。环境教育亦是一个不可缺少的环节,这篇文章将从环境教育面对环境问题应该怎么做进行分析,把环境教育氛围普通环境教育和专业环境教育,具体分析这两种环境教育类型在面对环境问题时的不同做法。

A transportation-location problem model for pedestrian evacuation in chemical industrial parks disasters

A successful emergency management for chemical industrial parks (CIPs) accidents includes the route and shelter selection. Both of them are based on the collection of chemicals, atmosphere, geographic and population databases of CIPs. This decision process can be considered as a kind of transportation-location problem (TLP). In this paper, a conceptual model of emergency decision system for TLP of CIPs has been reported and a new multi-objective TLP model of pedestrian evacuation has also been proposed. The model includes sub-criteria, and the affected areas are categorized into a priority hierarchy based on human vulnerability model (HVM). The model can be used to design shelter places and guide the evacuation of the affected people. Besides, it can maximize the total time satisfaction level of evacuees combined with the routes passable probabilities. Finally, a case study shows that this model is flexible and applicable to various scenarios and risk measures.
