中国交通安全技术分析

笔者在分析和比较中、美、日等国道路交通现状、交通安全的发展趋势、已采取相应对策及其实施效果的基础上 ,对我国现阶段交通特点、交通安全的状况、交通安全技术特征以及发展趋势进行了研讨和分析 ,并强调在交通安全管理的总体框架下 ,交通安全技术手段的提高是我国交通安全管理面临的迫切需要解决的问题 ,从而提出只有通过实施分阶段的、递进的安全管理对策和开展长效管理 ,提高交通安全技术 ,建立“点—线—面”的立体控制系统和道路交通安全保障体系 ,才能提高我国交通系统的整体安全性能     

石油野外施工作业OSH、HSE管理

长庆钻井野外施工作业队伍依据OSH，HSE管理体系的基本要求和国际通用做法，吸取与壳牌公司在长北区块的合作经验。学习国际上杜邦，阿莫科等石油公司的HSE合作案卷，翻阅了苏丹中国项目组HSE例卷，结合长庆钻井的实际情况。在野外施工作业队伍实施OSH，HSE管理，创新了17项管理技术。提升了作业队伍现场管理水平，步入与国际惯例接轨的行列，提高了经济效益。

职业安全健康管理体系的历史沿革及其在国内的发展现状

职业安全健康管理体系 (OSHMS)与ISO90 0 0和ISO14 0 0 0等标准化管理体系一起被称为是后工业化时代的管理方法 ,构成了现代企业管理制度的核心内容之一。笔者首先概述了职业安全健康产生的国际、国内背景以及历史沿革及当今发展概况 ;其次 ,提出了职业安全健康管理体系在市场准入机制、认证结果的客观性和公正性、“三标”一体化等方面应引起关注的一些问题 ;在此基础上预测了其将来的发展方向     

利用地理信息系统(GIS)开发多功能空管系统

在航空运输中 ,飞行安全最为重要 ,空管指挥是保证飞行安全的重要手段。地理信息系统 (GIS)能够将空间位置和性质属性结合在一起 ,非常适合空管指挥中直观性、安全性方面的需要。笔者在研究开发多功能空管系统的基础上 ,讨论了对地形、地物、航道、空管区、禁飞区等进行数字化的方法 ,提出了系统开发的主要技术 ,介绍了多功能空管系统的显示、控制、示警、辅助决策、智能纠错等功能 ,指出了空管系统的发展方向     

State Park Directors' Perceptions of Mountain Biking

/ This study intended to explore the perceptions of mountain bikingmanagement through a mail survey of state park directors in all 50 states.With a 100% response rate, it was found that 47 states permit mountainbiking in their state parks, however, few state parks have formalized plansto manage this outdoor activity. The management policies that do exist arenot followed on a statewide basis but vary within each state and at eachstate park. Many states have worked cooperatively with local mountain bikingclubs to develop and maintain mountain bike trails, promote rider education,and provide volunteer patrols on trails. The issue of user conflict surfacedwith almost three-fourths of the managers responding that conflict existedbetween mountain bikers and other trail users. This preliminary study shouldprompt further research with on-site managers focusing on the use ofmanagement plans for mountain biking, cooperation between managers and usergroups, and user conflict. It is recommended that an Internet-basedinformation clearinghouse or discussion group be made available to landmanagers by a national bicycling organization.KEY WORDS: Mountain biking; State parks; State park directors;Recreation resource management

Why ecosystem management can't work without Social science: An example from the California northern spotted owl controversy

It is increasingly obvious that social science, while not a sufficient condition for making ecosystem management effective, is a necessary condition. A social science typology of ecosystems is developed, applied, and shown to have substantial and unexpected implications for the practice of ecosystem management. Ecologists and environmental scientists, in particular, will find some conclusions uncomfortable. The application involves a case material from the California northern spotted owl controversy.     

SIMULATION OF TEMPORAL CHANGES IN RAINFALL-RUNOFF CHARACTERISTICS,COON CREEK BASIN,WISCONSIN1

ABSTRACT: Streamflow for 67 years was simulated for Coon Creek at Coon Valley, Wisconsin, for three conditions in the drainage basin: (1) conditions in the 1930s; (2) conditions in the 1970s, excluding flood-detention reservoirs; and (3) conditions in the 1970s, including flood-detention reservoirs. These simulations showed that the changes in agricultural practices over 40 years (1940–80) reduced the 100-year flood by 53 percent (from 38,900 to 18,300 cubic feet per second). The flood-detention reservoirs reduced the 100-year flood by an additional 17 percent (to 15,100 cubic feet per second). The simulation was accomplished by calibrating a precipitation-runoff model to observed rainfall and runoff during two separate periods (1934–40 and 1978–81). Comparisons of model simulations showed that differences between the model calibrations for the two periods were statistically significant at the 95 percent confidence level.
