Narratives Can Motivate Environmental Action: The Whiskey Creek Ocean Acidification Story

Even when environmental data quantify the risks and benefits of delayed responses to rapid anthropogenic change, institutions rarely respond promptly. We propose that narratives complementing environmental datasets can motivate responsive environmental policy. To explore this idea, we relate a case study in which a narrative of economic loss due to regionally rapid ocean acidification—an anthropogenic change—helped connect knowledge with action. We pose three hypotheses to explain why narratives might be particularly effective in linking science to environmental policy, drawing from the literature of economics, environmental policy, and cognitive psychology. It seems that yet-untold narratives may hold similar potential for strengthening the feedback between environmental data and policy and motivating regional responses to other environmental problems.     

A transportation-location problem model for pedestrian evacuation in chemical industrial parks disasters

A successful emergency management for chemical industrial parks (CIPs) accidents includes the route and shelter selection. Both of them are based on the collection of chemicals, atmosphere, geographic and population databases of CIPs. This decision process can be considered as a kind of transportation-location problem (TLP). In this paper, a conceptual model of emergency decision system for TLP of CIPs has been reported and a new multi-objective TLP model of pedestrian evacuation has also been proposed. The model includes sub-criteria, and the affected areas are categorized into a priority hierarchy based on human vulnerability model (HVM). The model can be used to design shelter places and guide the evacuation of the affected people. Besides, it can maximize the total time satisfaction level of evacuees combined with the routes passable probabilities. Finally, a case study shows that this model is flexible and applicable to various scenarios and risk measures.     

Safety in shipping: the human element

INTRODUCTION: There are numerous diverse papers that have addressed issues within maritime safety; to date there has been no comprehensive review of this literature to aggregate the causal factors within accidents in shipping and surmise current knowledge. METHODS: This paper reviewed the literature on safety in three key areas: common themes of accidents, the influence of human error, and interventions to make shipping safer. The review included 20 studies of seafaring across the following areas: fatigue, stress, health, situation awareness, teamwork, decision-making, communication, automation, and safety culture. RESULTS: The review identifies the relative contributions of individual and organizational factors in shipping accidents, and also presents the methodological issues with previous research. CONCLUSIONS: The paper concludes that monitoring and modifying the human factors issues presented in this paper could contribute to maritime safety performance. IMPACT ON INDUSTRY: This review illustrates which human factors issues are prevalent in incidents therefore this gives shipping practitioners a focus for interventions.     

Indoor air quality and academic performance

I examine the effect of school indoor air quality (IAQ) on academic outcomes. I utilize a quasi-natural experiment, in which IAQ-renovations were completed at virtually every school in a single Texas school district at different points in time, combined with a panel of student-level data to control for many confounding factors and thereby uncover the causal effect of IAQ-renovations on academic outcomes. Results indicate that performance on standardized tests significantly improves while attendance is unresponsive to improvements in IAQ. Rough calculations suggest that IAQ-renovations may be a more cost-effective way to improve standardized test scores than class size reductions.

Trend analysis of machinery safety for globalization: From the Japanese point of view

In Japan, the work of translation to JIS faced many obstacles. Support groups in Western countries have submitted comments on technical problems. The movement to standard harmonization in safety has rapidly developed in international standardization. The movement for global standardization is developing throughout all the economic areas of the EU. The aim of the Machine Directive that comes into effect in stages is to provide an international formula for a type of qualification in machine safety. EN292 is a nucleus for related standards, which are like a group of planets in a universe. It is a European standard as well as a guideline for implementation, showing practical safety requirements for machines. Horizontal standards, such as EN954 and IEC61508, apply in actual practice.     

危险评价中的数据环境

本文通过分析危险评价的数据来源、数据的准确程度和危险评价模型，论述了数据环境与危险评价的关系，指出了数据的不确切必然会影响到危险评价质量，但应用数据进行危险评价是完全必要的。关键是如何提高数据的精确程度和模型的真实程度，使评价结果更趋准确、可靠。     

A human ecological assessment of air quality management: A convergence in economic and ecological thinking?

Traditional air pollution management practices are examined using the human ecological framework adopted by Boyden and others (1981) in their study of Hong Kong—the biohistorical or biosocial approach. The subsequent analysis of current air quality management practices assesses their effectiveness in protecting the overall health of both humans and the natural environment. The uncertainties inherent in air pollution management practices which emerge highlight the need to reduce emissions rather than rely on scientific knowledge to define clean air. The assessment also clearly defines roles for research in various areas such as atmospheric models, health effects, and environmental damage. The final recommendations emphasize the need for the introduction of such incentives to reduce emissions as economic instruments and warn against using health information to define clean air. Health and environmental damage information can, however, be used in risk assessment strategies together with atmospheric dispersion models.
