Implementation and evaluation of the Safety Element Method at four mining sites

The Safety Element Method (SEM) is a method for improvements of safety results and safety approaches in the Norwegian mining industry. The method is developed by users and researchers in co-operation. The main approach of the method is that a group of organisational members assesses the current and desired situation for their own organisation within defined areas. Based on this assessment they work out a strategy and action plan to reach the internal goals for desired achievement, i.e. the desired situation defined. This article presents the implementation of the method in four mining companies and evaluates the method for its construct validity, criterion validity, face validity, how the method functions and is accepted among the users. The results show that the opinions regarding the experiences with the method are, on the whole, positive. The method is regarded as a valuable approach towards safety improvements. Subjective assessments play a prominent role in SEM, but these assessments are supported by an extensive review of empirical data such as accident reports, interview results and a questionnaire. This means that the internal assessments correspond well to the safety results of the companies and also to the independent external reviews carried out by the researcher.

炸药及火工品可靠性与安全性评定方法

可靠性的评定结果是否可信,直接关系到炸药及火工品的使用安全性和作用可靠性。但是,现有炸药及火工品可靠性评定方法却存在着达不到置信度要求、评价结果偏于危险的缺点。为此,提出了一种确定炸药及火工品安全度和可靠度的高精度方法,并给出了应用实例。该方法不仅可信程度高,而且适用于小样本情况,尤其是在利用了以往试验数据后,既可提高安全性和可靠性评定的精度,又可大大节省试验的费用及时间

Establishing a Regional Monitoring Strategy: The Pacific Northwest Forest Plan

adaptive monitoring design. Adaptive monitoring design is an iterative process that refines the specifications for monitoring over time as a result of experience in implementing a monitoring program, assessing results, and interacting with users. An adaptive design therefore facilitates ecosystem management. We also discuss lessons of temporal and spatial scales raised by the consideration of a design for ecosystem management. Three additional issues—integration of information from different sources, institutional infrastructure, and the roles of individuals working in an interagency setting—are also identified, but not developed in detail.     

Cooperative Solutions for Sustainable Resource Management

n -person game theory are most appropriate for these problems because they focus on the conditions for engendering and sustaining the necessary cooperation among the involved stakeholders. These solution concepts seek to ensure that the allocation is based on some norm of equity and, most often, also to minimize the incentive for any player to defect from the cooperative venture. We illustrate these solution concepts with an application to a water resource project in Southern California. We argue how the rigorous mathematical nature of these solution concepts should not hinder their application to actual situations and how, with the use of heuristic rules and inexact notions of comparable worths, we can employ these concepts even in approximate fashion. We remind ourselves that the goal of such an endeavor is to convince stakeholders of the equity of a proposed solution and, in so doing, maximize the prospect of sustained cooperation. The alternative to cooperation, on the other hand, may be endless stalemate.
