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

深度休闲对优化苏南地区休闲产业建设,进一步提升居民休闲生活质量有重要影响。文章通过问卷调查的方式收集苏南地区城市居民深度休闲行为的数据,研究苏南地区城市居民深度休闲行为特征及深度休闲对主观幸福感的影响。结果发现:(1)苏南地区城市居民进行深度休闲活动的场所主要为户外;(2)闲暇时间不足是限制苏南地区城市居民进行深度休闲活动的主要因素;(3)苏南地区城市居民的深度休闲活动总体程度不高,愿意在深度休闲活动上投入大量时间和金钱的人更是少数;(4)苏南地区城市居民从事深度休闲活动产生的强烈认同感和坚持不懈的毅力对主观幸福感有着显著的积极影响。  相似文献

Abstract

Here we describe the implementation of an experimental research tool called the Decision Game that we used to collect data on household flood risk management decisions. Participants using this tool play an interactive game that involves making household decisions about place of residence and a variety of household expenditures, including spending on flood insurance and private flood risk mitigation. Participants also answer survey questions before and after playing the game; the pre-game survey collected demographic information, and the post-game survey collected information about participant experiences with flooding and flood mitigation. Online and face-to-face participants showed similar engagement with the experiment, and most participants appeared to have made deliberate and considered decisions about risk mitigation. Online study participants had similar responses to those who participated in person, although face-to-face participants seemed slightly more likely to mitigate against risk. Overall, participants in this research were younger, more educated and more likely to rent a home than the average Canadian. Serious games may be useful for augmenting existing data gathering strategies used in understanding environmental decision making, particularly for rare catastrophic events for which stated preference surveys may be less informative. Serious games allow for sharing a mixture of information with study participants, including maps, video clips, text and even immersive 3D experiences, and can be administered online to increase participation levels. Future research will consider longer duration online experiments and more immersive interaction frameworks.  相似文献

We propose a tractable framework for quantifying the impact of loss‐triggered fire sales on portfolio risk, in a multi‐asset setting. We derive analytical expressions for the impact of fire sales on the realized volatility and correlations of asset returns in a fire sales scenario and show that our results provide a quantitative explanation for the spikes in volatility and correlations observed during such deleveraging episodes. These results are then used to develop an econometric framework for the forensic analysis of fire sales episodes, using observations of market prices. We give conditions for the identifiability of model parameters from time series of asset prices, propose a statistical test for the presence of fire sales, and an estimator for the magnitude of fire sales in each asset class. Pathwise consistency and large sample properties of the estimator are studied in the high‐frequency asymptotic regime. We illustrate our methodology by applying it to the forensic analysis of two recent deleveraging episodes: the Quant Crash of August 2007 and the Great Deleveraging following the default of Lehman Brothers in Fall 2008.  相似文献

This article reflects on aligning leisure research with the local foods movement while placing the local foods movement into the larger framework of sustainability and the fields of leisure and recreation. The local foods movement has persisted during difficult economic times; growth in local foods venues and young people endeavoring to establish small-scale sustainable farms continues to flourish. Given the history of leisure research and its continued success alleviating participation barriers and constraints, the need for leisure researchers to focus on local food systems is imperative and timely. This essay highlights the notion of leisure in living through local foods and the serious leisure aspects of small-scale sustainable agriculture. This article also encourages leisure researchers to explore and assess the relationships between the local foods movement and small-scale farming as embedded in the larger framework of sustainability.  相似文献
