Decisions are often needed about the need and/or extent of protective measures against explosive blast loads on built infrastructure. A decision support analysis considers fatality risks and cost-effectiveness of protective measures expressed in terms of expected cost spent on risk reduction per life saved for terrorist threats to infrastructure. The analysis is applicable to any item of infrastructure, but in this paper is applied to casualties arising from building facade glazing damage. Risks may be compared with risk acceptance criteria in the form of quantitative safety goals. The risk acceptability and cost-effectiveness of protective measures includes cost of the protective measures, attack probability,reduction in risk due to protective measures,probability of fatality conditional on successful terrorist attack and number of exposed individuals.  相似文献

The increasingly sedentary American lifestyle has resulted in a growing number of overweight and out-of-shape school-age children. Deaf children are not exempt from this trend, yet there is little evidence that public school programs for these children are doing anything to counter it. Much can be done to assist deaf students, not only in becoming more active movers but in gaining knowledge of opportunities and benefits associated with Deaf sport. The authors provide an argument for schools that expose deaf children to the role of sports in the Deaf community and for designing programs that will enable these children to become active participants in Deaf sport activities as athletes and organizers, or, later in life, when they no longer have the inclination or ability to compete, as spectators, with all the socialization benefits that form of involvement provides.  相似文献

We examined the degree to which content of states’ writing standards and assessments (using measures of content range, frequency, balance, and cognitive complexity) and their alignment were related to student writing achievement on the 2007 National Assessment of Educational Progress (NAEP), while controlling for student, school, and state characteristics. We found student demographic characteristics had the largest effect on between-state differences in writing performance, followed by state policy-related variables, then state and school covariates. States with writing tests that exhibited greater alignment with the NAEP writing assessment demonstrated significantly higher writing scores. We discuss plausible implications of these findings.  相似文献

Cadavers play an important role in anatomy education. In Australia, bodies for anatomy education are acquired only through donations. To gain insight into educational dynamics in an anatomy laboratory as well as to facilitate body donation programs and thanksgiving ceremonies, it is important to understand students' attitudes toward body donation. In this cross‐sectional study, the attitudes of Macquarie University's first, second, and fifth year chiropractic students toward body donation were investigated. Macquarie University chiropractic students have a four semester long anatomy program, which includes cadaver‐based instruction on prosected specimens. A questionnaire was used to record respondents' demographics and attitudes toward body donation: personal, by a relative, and by a stranger. It was found that ethnicity and religion affect attitudes toward body donation, with Australian students being more willing to donate a stranger's body and atheists and agnostics being more willing to donate in general. Furthermore, willingness to donate one's own or a family member's body decreases as year of study increases, suggesting a possible negative impact of exposure to cadavers in the anatomy laboratory. This was only true, however, after controlling for age. Thus, the impact of viewing and handling prosected specimens, which is the norm in anatomy classes in Australia, may not be as strong as dissecting cadavers. It is suggested that anatomists and educators prepare students for cadaver‐based instruction as well as exhibit sensitivity to cultural differences in how students approach working with cadavers, when informing different communities about body donation programs and in devising thanksgiving ceremonies.
