To support organisations in addressing their safety culture, practical tools have been developed worldwide. Based on such practical tools, it is possible to measure where an organisation is situated regarding its safety culture in order to identify priority areas, formulate appropriate improvement strategies and determine changes over time. In this paper, it is examined which practical tools to measure and improve safety culture are provided on the Belgian market. In total, 15 Belgian tools were identified, of which 8 agreed to cooperate. Amongst the included tools, there is a lot of variation regarding the methods to diagnose the safety culture and the overall procedure to improve the safety culture. The importance to adapt the tool to the specific needs and context of organisations is acknowledged in most of the tools, as well as the importance to use a multi-method approach to measure the safety culture. Also, it is recognised that all hierarchic levels should participate during the process of diagnosing the safety culture. A point of attention is this overall participation during the validation of the results of the diagnosis, and the priority setting of the recommendations, which is mainly done by the higher management. The development of the Belgian tools is based on experience with a focus on direct practical application, which leads to the fact that none of the tools are validated through scientific evidence. Another point of attention is that organisations pay too little attention at the continuity of safety culture research. And finally, the question can be raised if the safety culture tools actually address the concept ‘safety culture’, or if they address only a subset of the concept. When safety culture is addressed, a comprehensive approach should be used, where technological, organisational, human and external aspects are taken into account as interacting and interrelating elements. 相似文献

Reducing injury and death in house fires is an important public health intervention activity with the presence of an operating smoke alarm widely considered an important way of reducing harm from fire. Yet despite a number of initiatives and fire-safety campaigns, a number of households at greater risk of domestic fire fail to have a functioning alarm. This paper provides empirical insight into everyday experiences of owning, maintaining and testing smoke alarms among a purposive sample of individuals identified as being less likely to own a functioning smoke alarm. Analysis from focus group data identifies a number of reasons why individuals may not own or test an alarm, and provides new insight into how fire risk is understood in the context of a range of competing, and potentially more prominent, individual and household risks. We suggest that while initiatives that aim to reduce fire injury and death should be continued, their success, and indeed future research on fire risk, should pay attention to the mundane and everyday contexts within which individuals currently rarely reflect on their risk of experiencing a domestic fire. 相似文献

This paper re-examines the purchasing power parity (PPP) hypothesis for a panel of ASEAN-5 countries. The panel unit root and cointegration tests, which incorporate cross-sectional dependence and multiple structural breaks, are innovatively used for testing the PPP hypothesis. We could not find evidence that supports the existence of a long-run equilibrium between the relative price ratio and the nominal exchange rate for the whole period. Nevertheless, there is evidence of a cointegrating relationship for the post-crisis period. Our finding implies that a flexible exchange rate regime is suitable for the individual ASEAN countries. 相似文献

E. coli O157:H7 is an important source of foodborne disease. The E. coli pathogen occurs naturally within the rumen of livestock (including cattle) and does not affect the health of the cattle, however, can be a source of cross-contamination during food processing or environmental contamination of drinking and irrigation water supplies. A vaccine to reduce the risk of cattle shedding E. coli is licensed for use in Canada and the US, however, adoption of the vaccine by cattle producers has been extremely low. Using data from a survey of cow–calf producers in western Canada, the influence of a set of thirteen incentives to encourage adoption of the vaccine is examined using Best–Worst Scaling. Incentives include policy interventions, market/supply chain incentives, production protocol incentives, and producer reputation incentives. Heterogeneity in producer responses to the incentives is evident and is further explored with a Latent Class Cluster analysis. Results suggest that a ‘one size fits all’ policy to encourage adoption of an E. coli vaccine by cattle producers may be challenging. 相似文献
