上市公司环境信息披露法律研究——以环保部门的监管为视角

随着环境信息公开制度的建立和公众知情意识的觉醒,人们对环境信息公开的呼声越来越高。不仅政府基于其环境监督管理的职能需要公开环境信息,企业基于对环境产生影响也需要依法公开环境信息。而上市公司作为具有特殊地位的企业,其在环境信息披露中的重要性不可小觑。近年来屡屡发生的上市公司环境污染事件也一再提醒环境监管部门和广大社会公众,亟需对上市公司环境信息披露进行有力监管。本文试从环境保护监管部门的角度论述目前法律法规对上市公司环境信息披露在披露内容和披露方式上的不足和改进建议。期望能引起环境保护部门和上市公司相关部门的注意,从而推动上市公司环境信息披露制度的不断完善。     

Microstructure of 2205 duplex stainless steel joint in submerged arc welding by post weld heat treatment

The 2205 duplex stainless steel (DSS) is of both good properties austenitic steel and ferritic steel, which applies to the shipbuilding industry usually. In this paper, the OM, XRD and microhardness test methods are used to analyze the variation of submerged arc welded (SAW) joints with and without post weld heat treatment (PWHT). The research results show that the σ phase disappear in the fusion edge zone near heat affect zone (HAZ) and an increase in the welded center zone during the follow-up PWHT, while the amount of γ phase is decreased in the welded center zone with PWHT. A segregation distribution of some second phases is also found in the welded center zone after PWHT. There have two pick values of microhardness arise in the fusion edge zone and the welded center zone separately without PWHT. However, a maximum value of microhardness at the fusion edge zone near HAZ is disappeared and the other is still held at the welded center zone during PWHT. It can be attributed to the changes of second phases, element diffusions and particle segregation during PWHT. A developing mechanism is issued to demonstrate the second phases transferring of the 2205 DSS SAW joints by PWHT.     

基于文本挖掘的煤矿安全隐患管理研究

为探寻安全隐患的内在特征,加深安全管理人员对安全隐患的理解,提升安全管理效率。以潞安集团司马煤业有限公司2009—2015年安全隐患记录为数据源,利用Word2Vec模型构建安全隐患词向量模型,从模型中获取各类安全隐患主要相关词,利用桑基图解释安全隐患在不同隐患地点、生产作业单位的特征分布,并进一步揭示相关安全隐患的细节特征。结果表明:词向量模型能有效发掘安全隐患特征,桑基图能突出呈现安全隐患的关键信息流动。上述措施有助于管理人员深刻理解安全隐患数据中蕴含的潜在规律,为煤矿安全隐患排查治理工作提供依据,指导安全管理实践。     

于GRI体系的机场企业环境信息披露研究

机场作为民航运输的关键节点和重要枢纽,肩负着服务区域经济的重要使命,同时也面临环境保护与可持续发展的巨大挑战。作为公共基础设施和城市形象窗口,机场上市公司具有披露环境信息的义务与责任。在充分研究国内机场上市公司环境信息披露制度背景的基础上,本研究借鉴全球报告倡议组织（GRI）发布的《可持续发展报告指南》（第四版）及机场运营者行业补充（GRI-AOSS）构建了适用于我国机场的环境信息披露评价指标体系,并利用公开数据对国内6家机场上市公司的环境信息披露情况进行了实际测评。结果表明：我国机场环境信息披露程度较低,存在内容简单、量化不足、质量下降等问题。机场上市公司环境信息披露亟待在法律法规层面进行系统规范。建议借鉴GRI等相关国际标准及成功经验,制定适用于我国的科学可行的环境信息披露标准和制度体系。     

基于内容分析法的土地利用总体规划目标偏好研究

土地利用总体规划需要统筹区域发展多元目标以增强对区域发展的指导力和约束性,因此全面了解我国土地利用总体规划的政策目标偏好,能为优化规划技术方法和改革规划管理体制提供政策参考。鉴于此,本文在分析我国土地利用总体规划多元目标及其关系的基础上,采用内容分析法基于全国土地利用总体规划纲要进行词频挖掘构建目标偏好测量维度及体系,进而对两轮省级土地利用总体规划文本进行目标偏好的定量测度,结果表明:(1)土地利用总体规划是多目标规划,通过内容分析法可以构建由经济、社会、生态三大目标构成的目标偏好测量体系;(2)从目标偏好排序来看,三大目标中社会目标始终是两轮土地利用总体规划的首要偏好目标,生态目标是土地利用总体规划的次要偏好目标,经济目标排在最后;同时相比上轮规划,本轮规划耕地保护子目标次序提前,土地整治子目标次序推后;(3)从目标偏好程度来看,社会目标的首位偏好程度有所下降,但其中耕地保护子目标的首位偏好度明显上升;生态目标和经济目标的首位偏好程度基本不变,总体而言本轮规划三大目标偏好程度的差异缩小。研究结果说明,我国土地利用总体规划始终坚持以耕地保护为核心的社会目标偏好,符合其是国土资源管理部门主导的部门规划的定位;虽然土地利用总体规划对经济、社会、生态三大目标的偏好程度差异缩小,但其若要在空间规划体系中发挥更大的作用,还需要通过优化规划技术和改革规划管理体制进一步均衡经济、社会、生态目标,以承担起统领全区域空间发展的要求。     

A summary and synthesis of procedural regulations and standards—Informing a procedures writer's guide

Well-written procedures are an integral part of any industrial organization for safe operation, managing risks, and continuous improvement. Regulatory bodies around the world require industries to have current, accurate, and appropriate procedures for most processes. Although the importance of procedures is recognized by all industries in general, significant incidents still occur due to procedural breakdowns. Some of the procedural breakdowns come from obvious problems such as the procedure not being available or the procedure being wrong. However, some incidents have occurred when correct procedures were available and the operator used those procedures. In these instances, the reason workers do not follow procedures correctly may be attributable the procedure being presented or designed in a manner that does not sufficiently communicate the information in a manner that is easily and quickly understood. This indicates that procedure writers may need more guidance on how to write and design procedures so they accomplish this. To effectively manage risk, procedures need to be technically correct (and regulatory compliant) and usable. As part of this, the current work is focused on developing a systematic approach to a procedure writer's guide that includes a regulatory compliant component. The work presented here consists of an effort to identify procedure-writing practices necessary to ensure regulatory compliance by summarizing a large sample of regulations and standards from several industries. The regulations and standards were organized to reflect common ideas and the implications in terms of human factors needs for procedure design were identified. This information will be used as part of the development of a writer's guide that accounts for human factors (HF) that includes explanations of HF implications and empirical support for each of the guidelines. The novelty of the method and information presented here is in the idea of leveraging the cumulative information available regarding procedures in regulations and standards. Incorporating this information into a procedure's writers guide in this manner may not only facilitate procedure being regulatory compliant for facilities in different geographies of the world, but could also support their being written with considerations for human performance.
