Summary. We detail a general method for measuring agreement between two statistics. An application is two ratios of directly standardized rates which differ only by the choice of the standard. If the statistics have a high value for the coefficient of agreement then the expected squared difference between the statistics is small relative to the variance of the average of the two statistics, and inferences vary little by changing statistics. The estimation of a coefficient of agreement between two statistics is not straightforward because there is only one pair of observed values, each statistic calculated from the data. We introduce estimators of the coefficient of agreement for two statistics and discuss their use, especially as applied to functions of standardized rates. 相似文献

Seismic risk can be reduced by implementing newly developed seismic provisions in design codes. Furthermore, financial protection or enhanced utility and happiness for stakeholders could be gained through the purchase of earthquake insurance. If this is not so, there would be no market for such insurance. However, perceived benefit associated with insurance is not universally shared by stakeholders partly due to their diverse risk attitudes. This study investigates the implied seismic design preference with insurance options for decisionmakers of bounded rationality whose preferences could be adequately represented by the cumulative prospect theory (CPT). The investigation is focused on assessing the sensitivity of the implied seismic design preference with insurance options to model parameters of the CPT and to fair and unfair insurance arrangements. Numerical results suggest that human cognitive limitation and risk perception can affect the implied seismic design preference by the CPT significantly. The mandatory purchase of fair insurance will lead the implied seismic design preference to the optimum design level that is dictated by the minimum expected lifecycle cost rule. Unfair insurance decreases the expected gain as well as its associated variability, which is preferred by risk-averse decisionmakers. The obtained results of the implied preference for the combination of the seismic design level and insurance option suggest that property owners, financial institutions, and municipalities can take advantage of affordable insurance to establish successful seismic risk management strategies. 相似文献

由于历史和现实的缘故,国民政府十分关注海外华侨尤其南洋华侨的教育,形成了比较完善的华侨教育体系,学校和学生数量呈上升趋势,学生素质也不断提高。然而由于国民政府侨教政策自身固有的弊病,给南洋侨教带来了相当的消极作用,限制了南洋侨教事业的进一步发展。 相似文献

This study examines housing quality among three groups of single-parent women: white, African-American, and Hispanic. Three
indicators of housing quality—crowding, affordability, and satisfaction—are used to discover the extent to which these groups
experience housing problems. This study also explores differences and similarities in the factors that precipitate problems
in housing quality for these three groups of single parents. Findings suggest important differences and similarities in the
nature of housing quality problems among white, African-American, and Hispanic single-parent women. The specified variables
explained about 20% of the variance in crowding, housing affordability, and housing satisfaction. On measures of objective
and subjective housing quality, white single mothers are better housed than their African-American or Hispanic counterparts.
Hispanic single mothers have the largest housing cost burden and average more persons per household than the other groups.
African-Americans are twice as likely as either group to live in low-quality housing and reported the lowest average satisfaction
with their housing.
Her research interests include housing and neighborhood assessment and women and public policy issues. She has recently published
articles inUrban Affairs Quarterly andHousing and Society on housing and neighborhood assessment criteria among black urban households and the housing cost burden of various groups
of female-headed households. She received her Ph.D. from Ohio State University.
Her research interests include the housing adjustment behavior of women and public policy. She has recently completed her
thesis on the role of noncustodial parents in determining the quality of life of their children. She is also the recipient
of the Tessie Agan Award for research excellence from the American Association of Housing Educators for a paper titled “Unterstanding
Constraints and Residential Satisfaction among Low-Income Single-Parent Families.” 相似文献
