Evaluation of hazard brochures using topic viewing durations: Application to tsunami evacuation brochures

This study describes a novel method of assessing risk communication effectiveness by reporting an evaluation of a tsunami information brochure by 90 residents of three Pacific coast communities that are vulnerable to a Cascadia Subduction Zone earthquake and tsunami—Commencement Bay, Washington; Lincoln City, Oregon; and Eureka, California. Study participants viewed information that was presented in DynaSearch, an internet-based computer system that allowed them to view text boxes and tsunami inundation zone maps. DynaSearch recorded the number of times each text box or map was clicked and the length of time that it was viewed. This information viewing phase was followed by questionnaire pages assessing important aspects of tsunami hazard and sources of tsunami warnings. Participants gave the longest click durations to what to do in the emergency period during earthquake shaking and in its immediate aftermath before a tsunami arrives—topics that should be displayed prominently in tsunami brochures and emphasized in talks to community groups. The smallest adjusted click durations were associated with advance preparations for a tsunami—topics that can be posted on websites whose URLs are printed in the brochures.     

Economic models of evaluation

Economic approaches to evaluation have become very popular as governments try to reduce costs and cut programs. However, one must be careful in conducting such analyses, especially cost-benefit analyses, as they sometimes exclude significant criteria that the evaluator must consider at the risk of being incorrect.     

Shaking the bad boys: troubling the criminalization of black boys’ childhood play,hegemonic white masculinity and femininity,and the school playground-to-prison pipeline

ABSTRACT

Few studies have sought to understand the childhood play experiences of Black boys in early childhood education (ECE), and a majority of those that investigate them often socially construct Black boys’ play as criminal, dangerous, and monstrous. Considering the dangers of hegemonic masculinity and femininity or the racial and gendered power and privilege White boys and girls bring to societal spaces including playgrounds, little is known about how such power influences the experiences of Black boys who play with them. In this conceptual paper, I draw on critical race theory (CRT) to trouble the criminalization of Black boys’ childhood play and hegemonic White masculinity and femininity, which can prove violent and dehumanizing to Black boys. As such, I suggest that similar to the school-to-prison pipeline (STPP), Black boys may become victims of what I call the school playground-to-prison pipeline (SPTPP) as a consequence of White children’s accusations, fears, misperceptions, and misreadings of Black boys’ play. Recommendations are provided for teacher and ECE to better support Black boys and the cross-cultural play interactions between them and White children.     

以价值为本领导行为与领导效能在中国的实证研究

以价值为本(value based leadership)的领导理论是沃顿商学院豪斯(House)在综合了70年代以来的领导理论后提出的,代表了最新的领导学理论进展,对这一理论的研究和推广在豪斯的领导下正在世界62个国家兴起,本文在豪斯项目基金和国家自然基金的支持下研究以价值为本的领导学理论在中国的有效性,是全球跨文化领导学项目在中国的部分.本文在95家企业访谈和问卷调查的基础上,对以价值为本的领导行为与领导有效性之间的关系进行了分析.结果表明,以价值为本的领导理论非常适合中国的经济环境,这种领导行为能导致下属的高度认同、满意和激励.本篇论文的特别贡献是用量化方法实证了企业竞争环境、领导的职业发展历程等情景因素对领导有效性的间接影响作用,企业领导者的发展及成长历程对领导行为的有效性有直接的影响,从而对价值型领导理论有所发展.     

西方现代科学主义思潮的来源与发展

西方现代科学主义思潮的核心内容是科学理性精神。科学理性精神最早起源于古代希腊,在近代有了长足的发展,以至产生了怀疑主义、经验主义、理性主义和科学唯物主义等多种表现形式。到了现代,科学主义又以实证主义、经验批判主义、逻辑经验主义和实用主义等形式出现。它不仅深深影响着西方社会经济、政治、文化的发展,而且对许多后起的现代化国家和民族产生了重大影响。     

Private Information and Insurance Rejections

Across a wide set of nongroup insurance markets, applicants are rejected based on observable, often high‐risk, characteristics. This paper argues that private information, held by the potential applicant pool, explains rejections. I formulate this argument by developing and testing a model in which agents may have private information about their risk. I first derive a new no‐trade result that theoretically explains how private information could cause rejections. I then develop a new empirical methodology to test whether this no‐trade condition can explain rejections. The methodology uses subjective probability elicitations as noisy measures of agents' beliefs. I apply this approach to three nongroup markets: long‐term care, disability, and life insurance. Consistent with the predictions of the theory, in all three settings I find significant amounts of private information held by those who would be rejected; I find generally more private information for those who would be rejected relative to those who can purchase insurance, and I show it is enough private information to explain a complete absence of trade for those who would be rejected. The results suggest that private information prevents the existence of large segments of these three major insurance markets.     

Attendance at religious services and mortality in a national sample

Research and theory increasingly suggest that attendance at religious services is protective against premature mortality. However, prior studies are limited and do not extensively explore potential explanations for the relationship, especially in terms of religious beliefs and behaviors associated with service attendance. This study estimates the impact of service attendance on mortality in a national probability sample and provides the most extensive empirical examination of potential explanations. Individuals who report attending religious services once a month or more (just over 50 percent of the population) have a 30-35 percent reduced risk of death over a 7.5 year follow-up period after adjusting for potential confounding factors. Consistent with prior research, 20-30 percent of this effect may be explained by better health behaviors (especially physical activity) among regular service attendees. Surprisingly, other religious beliefs and behaviors do not explain, and often tend to suppress, the association between service attendance and mortality.
