Public Opposition to a Proposed Nuclear Waste Repository in Canada: An Investigation of Cultural and Economic Effects

Residents of four northern communities were surveyed about Atomic Energy of Canada Limited's proposal to site an underground repository for high-level nuclear waste somewhere in the Canadian Shield. Opposition to the repository was relatively strong in all communities, but was strongest among aboriginal respondents. Path analysis revealed that trust in nuclear regulators, faith in science and technology, and anticipated net costs were important mediators of this effect. Aboriginals were less trusting, exhibited less faith in science and technology, and perceived the costs associated with the repository to be higher than their nonaboriginal counterparts. No support was found for the hypothesis that, after controlling for aboriginal status, financially insecure individuals would display greater support for the nuclear waste repository than financially secure individuals. Policy implications for balancing perceived risks and siting needs are discussed.     

农业产业化风险和农业保险

通过与传统农业经营方式比较 ,农业产业化必然增加农业经营风险。在目前的农业产业化经营组织模式下 ,农民是农业产业化的风险实际承担者 ;要使农业产业化在我国有很好的发展 ,必须建立相应的风险转移制度。我国和国外的实践都表明 ,建立农业的商业和政策保险是农业产业化的必然选择。     

新产品概念的评价与选择

吸引力是评价新产品概念的综合性指标,它由核心吸引力和扩张吸引力构成。在高技术产业中,投资回收期的引入使吸引力指标的评价更具有实践指导意义。理念化程度是评价新产品概念的另一个重要指标,理念化的产品概念融入公司的愿景,成为企业文化的一个核心要素和经营理念的一个基本组成。有效地评价和选择新产品概念,保证新产品开发和创业投资的成功与高效率,要有足够数量的备选产品概念供选择。     

Using Automated Emergency Notification Systems to Inform the Public: A Field Experiment

Research and experience have shown that it can be difficult to get citizens to pay attention to risk messages and preparedness information in the absence of an actual emergency. As the use computerized systems that alert the public to hazards by automatically ringing their home phones increases, we thought it important to ask if tests of these "call down" systems can also be used to convey preemergency information. We worked with a local government to add instructions on how to shelter-in-place to the message on a routine test of a call down system. We then surveyed a test group and a control group before and after the test call and a second control group on after the call. The results indicate that the test call raised awareness of the emergency notification system without generating undue concern about the possibility of a chemical accident. Those who received the test call demonstrated significant improvements in their knowledge of how to shelter-in-place while no such improvement was observed in those who did not get the call. While the nature of the sample used in this study limits generalizability, we feel this outcome is positive enough to warrant further exploration of this method of disseminating risk information and preparedness instructions.

Analysis of longitudinal multiple-source binary data using generalized estimating equations

Summary.  We present a multivariate logistic regression model for the joint analysis of longitudinal multiple-source binary data. Longitudinal multiple-source binary data arise when repeated binary measurements are obtained from two or more sources, with each source providing a measure of the same underlying variable. Since the number of responses on each subject is relatively large, the empirical variance estimator performs poorly and cannot be relied on in this setting. Two methods for obtaining a parsimonious within-subject association structure are considered. An additional complication arises with estimation, since maximum likelihood estimation may not be feasible without making unrealistically strong assumptions about third- and higher order moments. To circumvent this, we propose the use of a generalized estimating equations approach. Finally, we present an analysis of multiple-informant data obtained longitudinally from a psychiatric interventional trial that motivated the model developed in the paper.
