安全科学学及其应用探讨

为使安全科学学进一步具体化,明确阐述了安全科学学的定义、主要内容和可能的应用方面。研究表明:安全科学学是以安全科学为直接研究对象的科学;安全科学学的主要内容有安全科学的基本问题、基础理论和构建分类系统3个主要方面;安全科学的基本问题有基本概念、研究对象等10个,安全科学的基础理论主要有线性、非线性事故致因理论2类,根据安全科学的基本问题、基础理论构建出来的安全科学新分类系统由4个二级、13个三级及其下若干四级及五级分支学科组成。安全科学学对安全学科建设、安全实务都起着具体的支撑作用。     

基于链式中介效应的辱虐管理与安全绩效关系研究

为明晰辱虐管理、自我损耗和工作倦怠对安全绩效的作用机理,在文献研究和开放式访谈的基础上,建立四者关系的假设模型。采用辱虐管理量表、自我损耗量表、工作倦怠量表和安全绩效量表对389名员工进行调查,通过SPSS和AMOS进行相关分析和中介效应检验验证假设模型。结果表明,辱虐管理、自我损耗和工作倦怠两两之间均呈显著正相关,而辱虐管理、自我损耗和工作倦怠三者均与安全绩效呈显著负相关。辱虐管理不仅可以直接预测安全绩效,还可以通过3条路径间接影响安全绩效:通过自我损耗的独立中介作用;通过工作倦怠的独立中介作用;通过自我损耗和工作倦怠的链式中介作用。有效干预辱虐管理、自我损耗和工作倦怠,能提升安全绩效水平,减少人因失误。

论人的失误

人的失误所造成的事故占事故总数的７０—８０％，研究人的失误对控制伤亡事故的发生具有重要意义。为此，分析人的行为模式，论述人失误的原因，并对控制人失误的方法进行了探讨，认为减少人失误的根本途径是大力倡导安全文化，提高操作者的安全素质。     

USE OF MICROCOMPUTERS FOR THE MANAGEMENT OF WATER QUALITY DATA1

ABSTRACT: Information on raw water quality, treatment process removal efficiency, and distribution system monitoring is essential to the proper management and operation of a water utility system. Microcomputer hardware and software systems using commercially available data base management systems (DBMS) have emerged within the last few years as an effective means of managing, analyzing, and displaying water quality data. Understanding hardware, software, and training requirements is essential to the proper use of these systems. Three types of data base design are common: relational, hierarchical, and network. Only the relational type of data base architecture is widely implemented on microcomputer DBMS. In this paper two examples of the application of DBMS to water utility problems are presented. One example deals with collection and analysis of data concerning the water quality of the Mississippi River. The second example deals with the DBMS as a means of analyzing water quality data in the North Penn Water Authority (NPWA) distribution system.

The emergence of land systems as the nexus for sustainability transformations: This article belongs to Ambio's 50th Anniversary Collection. Theme: Agriculture land use

This perspective recognizes the seminal Ambio articles of Sombroek et al. (1993), Turner et al. (1994) and Brussaard et al. (1997), identifying their individual and collective role in laying the ground work for a global change research agenda on land and its human use through increased understanding of terrestrial ecosystem dynamics and global change, and furthering nascent interdisciplinary efforts within the global change science community to better understand the ‘human driving forces’ of change. From these efforts, land system science, as a systemic science focused on complex socio-ecological interactions around land use and associated trade-offs and synergies, emerges as an ‘interdiscipline’ challenged to better understand land systems as the ‘meeting ground’ for multiple claims on land for biodiversity, carbon, livelihoods, food production among others, and support pathways to sustainability for people and nature.
