大冶铁矿电力机车高压安全保护装置的改进

武钢大冶铁矿运输车间使用的是ZG150-1500型工矿电力机车,该电力机车原有1套高压保护装置,但是设计上局限于受电弓升落的控制,忽视了受电弓不能正常复位情况下的防触电保护功能,运输车间技术人员进行攻关,改进电力机车高压安全保护装置,增设高压接地保护设施,杜绝了电力机车高压触电事故发生,取得较好效果.

Describing and Mapping Human-Induced Vegetation Change in the Australian Landscape

Australian reporting requirements for native vegetation require improved spatial and temporal information on the anthropogenic effects on vegetation. This includes better linkage of information on vegetation type (e.g., native vegetation association), extent and change, vegetation condition, or modification. The Vegetation Assets, States and Transitions (VAST) framework is presented as a means for ordering vegetation by degree of anthropogenic modification as a series of condition states, from a residual or base-line condition through to total removal. The VAST framework facilitates mapping and accounting for change and trends in the status and condition of vegetation. The framework makes clear the links between land management and vegetation condition states, provides a mechanism for describing the consequences of land management practices on vegetation condition, and contributes to an understanding of resilience. VAST is a simple communication and reporting tool designed to assist in describing and accounting for anthropogenic modification of vegetation. A benchmark is identified for each vegetation association. Benchmarks are based on structure, composition, and current regenerative capacity. This article describes the application of the VAST framework as a consistent national framework to translate and compile existing mapped information on the modification of native vegetation. We discuss the correspondence between these compiled VAST datasets at national and regional scales and describe their relevance for natural resource policy and planning.     

Distribution-free ranked-set sample procedures for umbrella alternatives in the m-sample setting

In settings where measurements are costly and/or difficult to obtain but ranking of the potential sample data is relatively easy and reliable, the use of statistical methods based on a ranked-set sampling approach can lead to substantial improvement over analogous methods associated with simple random samples. Previous nonparametric work in this area has been concentrated almost exclusively on the one- and two-sample location problems. In this paper we develop ranked-set sample procedures for the m-sample location setting where the treatment effect parameters follow a restricted umbrella pattern. Distribution-free testing procedures are developed for both the case where the peak of the umbrella is known and for the case where it is unknown. Small sample and asymptotic null distribution properties are provided for the peak-known test statistic.     

The reality of “Revitalizing Health and Safety”

Problem: Workplace health and safety remains an important international socioeconomic issue, but the progressive declines in reported incidents may be slowing. The British Government has responded by launching a new policy initiative aimed at “Revitalizing Health and Safety” by establishing targets for improvement, strategies, and a series of action points, mainly targeting employers and organizational issues. This paper critically assesses the realities of implementing this policy with respect to the scientific base for each of the strategies. Method: Literature meta-analysis; analysis of policy. Results: Empirically proven determinants of workplace health and safety provide baselines for compensation and conditions of work, workforce characteristics, workplace characteristics, health and safety environment, political and economic factors, and industry characteristics. Support for different policy elements is varied and there are some significant gaps. Summary: An impressive body of research was found that offers a firm foundation for future developments. However, the need for work that is interdisciplinary, ordered, and collaborative is pressing. The need to move away from elegant but simplistic pictures of occupational health and safety (OHS) management practice, and to reflect true complexity is imperative. The reality of health and safety at work is that it is an issue that is taken lightly by those who do not practice or research safe and healthy working, and a serious issue for victims or relatives of victims of shoddy management. It remains one of the bastions of inequality of work worldwide. Impact on industry: The intent of governments in attempting to reinvigorate the suppression of workplace injury and illness is motivated by both social and economic imperatives. Motivation for organizations is not fully understood as there is no obvious business imperative. If organizations can further understand and provide a scientific justification for investment in OHS management, then governments' task will be made easier. By proving the value of OHS to management, we will demonstrate that organizations continue to present considerable hazards to their employees.
