Impact of safety attitude,safety knowledge and safety leadership on chemical industry workers’ risk perception based on Structural Equation Modelling and System Dynamics

In chemical industry, major accidents occur occasionally. Past research has demonstrated that risk perception was relevant to safety as it might affect the behavior, which could exert influence on the probability of accidents. It is important to adjust workers' risk perception to reduce accidents in chemical industry. To achieve this goal, some key influencing factors of workers’ risk perception of were identified from 3 aspects including safety attitude, safety knowledge and safety leadership. This was accomplished by gathering empirical data from 287 workers employed in 6 Chemical plants in Jiangsu, China. The model of influencing factors of risk perception for workers was established based on Structural Equation Modelling (SEM), and the path coefficients and weights were analyzed by the SEM. On that basis, the System Dynamics (SD) model of risk perception for workers was established. The study findings revealed safety attitude and safety leadership have a direct positive impact on perception of risk probability and perception of risk severity, safety knowledge has a direct positive impact on perception of risk severity, while safety knowledge has no direct positive impact on perception of risk probability. The findings of the study can provide theoretical supports and method guidance for adjusting the risk perception of workers in chemical industry.     

Natech guide words: A new approach to assess and manage natech risk to ensure business continuity

The risk posed by natural hazards to the technological systems is known as Natech risk. It is different from the more widely known and studied risk posed by such sites to the environment and society. Though currently, available risk assessment techniques recognize Natech, the specific qualitative technique for Natech risk assessment and reduction has not yet been developed. After analyzing past data of Natech accidents, relevant guide words have been suggested in this study. These guide words will help anticipate Natech risk and visualize the Natech scenario. Once the Natech risk is identified, corresponding risk reduction measures can be taken to avoid possible Natech accidents and consequences.

信息整合在城市综合防灾减灾中的应用

城市防灾减灾信息化建设中,"信息孤岛"问题造成信息资源的浪费,严重影响了灾害管理的效率和效果。笔者提出信息整合的思路——以信息共享和满足个性化需求为整合目标,按照标准化、相关性、价值性、动态性的整合原则,打破区域、部门间的界限,从横向、纵向、防灾减灾全过程进行信息整合,形成一套较完善的信息整合体系。为进一步明确整合主体(人)及整合对象(防灾减灾信息)之间相互联系和作用的方式,还介绍信息整合的3种模式:对象关联模式、逻辑模式、综合模式。在实践中,可以根据资源、技术、需求等方面的具体情况,单独地或综合地利用该3种模式进行信息内容的整合。通过信息整合能提升防灾减灾信息利用的整体效能,有效地发挥信息资源在防灾减灾中的作用。     

Synergisms between climate change mitigation and adaptation: an insurance perspective

As the world’s largest industry, the insurance sector is both an aggregator of the impacts of climate change and a market actor able to play a material role in decreasing the vulnerability of human and natural systems. This article reviews the implications of climate change for insurers and provides specific examples of insurance-relevant synergisms between adaptation and mitigation in the buildings and energy sectors, agriculture, forestry, and land use. Although insurance is far from a “silver bullet” in addressing climate change, it offers significant capacity and ability to understand, manage, and spread risks associated with weather-related events, more so today in industrialized countries but increasingly so in developing countries and economies in transition. Certain measures that integrate climate change mitigation and adaptation also bolster insurers’ solvency and profitability, thereby increasing their appeal. Promising strategies involve innovative products and systems for delivering insurance and the use of new technologies and practices that both reduce vulnerability to disaster-related losses and support sustainable development. However, climate change promises to erode the insurability of many risks, and insurance responses can be more reactive than proactive, resulting in compromised insurance affordability and/or availability. Public–private partnerships involving insurers and entities such as the international relief community offer considerable potential, but have not been adequately explored.
