Childhood drowning remains a serious public health problem worldwide. The Australian Water Safety Council has set as one of its highest priorities the reduction of drowning deaths in children aged 0–14 years. However, concerns have recently been raised that many students completing primary school still lack the ability to recognize potential aquatic risks, cope with emergencies or assist someone else in danger. In this study, 107 primary school children aged 11–12 completed a one day training programme led by surf lifesaving instructors. Pre, post and eight week follow-up measures showed statistically significant improvements in recognition of the red ‘beach closed’ flag, aquatic safety signs, how to identify a rip current and choosing the safest place to swim at a beach that included a rip current in the picture. Following training students were more willing to provide first aid assistance to family members and friends in an emergency situation. Findings reinforce the value of school-based training that provides a general foundation for aquatic safety, with the caveat that current programmes must be evaluated to ensure their content has a robust prevention focus.  相似文献

An increase of broadband demand is forecasted by transitional methods that consider the effect of this increase through many factors, such as customer requirement diversification, and new service introduction and deployment under competition. Broadband demand forecasting has become important for closing the digital divide, promoting regional developments, and constructing networks economically; therefore, a demand forecast model that considers the mechanisms of market structure is necessary. In this paper, a demand analysis method for broadband access combining macro- and micro-data mining is proposed, and the service choice behaviour of customers is introduced as a customer model not only to express the macro trend of market structure, but also to consider area marketing. The proposed method can estimate the potential demand, determine the point at which broadband demand growth peaks in a specified area, and support a decision for ultra high-speed broadband access facility installation.  相似文献

In recent years, below‐the‐line promotion has begun to shed its “Cinderella” image, and is starting to attract the sort of marketing budgets and academic attention that was previously only given to mass‐media advertising. However, there is a general consensus that sales promotion is still neither managed effectively, nor understood thoroughly when compared to more high‐profile above‐the‐line promotion. Improving the understanding and use of sales promotion will require academics and practitioners to analyse and understand each of the very different below‐the‐line techniques and their individual merits. This article is one of two which takes a detailed look at the use of sales promotion competitions.  相似文献

This paper examines the performance of auditors in generating hypotheses in an analytical review case both prior to and after review. It partitions two possible sources of gain from the review process, namely the discussion effect and the rank effect. The discussion effect compares review groups with and without discussion. The rank effect compares seniors and audit managers. The study found that the review process results in more plausible hypotheses being generated. Discussion within the review process between reviewer and reviewee was found to be one source of gain from the review process. While there was no difference in the performance of the senior and manager reviewers, managers completed the task in less time.  相似文献
