Federal and other regulatory agencies often use or claim to use a weight of evidence (WoE) approach in chemical evaluation. Their approaches to the use of WoE, however, differ significantly, rely heavily on subjective professional judgment, and merit improvement. We review uses of WoE approaches in key articles in the peer‐reviewed scientific literature, and find significant variations. We find that a hypothesis‐based WoE approach, developed by Lorenz Rhomberg et al., can provide a stronger scientific basis for chemical assessment while improving transparency and preserving the appropriate scope of professional judgment. Their approach, while still evolving, relies on the explicit specification of the hypothesized basis for using the information at hand to infer the ability of an agent to cause human health impacts or, more broadly, affect other endpoints of concern. We describe and endorse such a hypothesis‐based WoE approach to chemical evaluation. 相似文献

This article examines the spread of Disability Living Allowance across a group of low income households in an industrial town in North West England from the introduction of the new benefits in 1992 until the Spring of 1996. We focus on the changes over time of the incidence of Disability Living Allowance in the low income population and look at the relative spread of different elements of the benefit. We speculate on whether the new benefits have provided the most effective way of fulfilling the aims of the White Paper, The Way Ahead , and discuss the implications for social and medical models of disability. 相似文献

This paper argues that economic theories and econometric methods can constitute useful tools for the sociological study of
employment and gender. Work by the author and by Paula England is used to illustrate this point.
His research interests include labor markets, economic sociology, statistical methods, and policy analysis.
This article is based on a paper presented at the Southern Sociological Association meetings held in Nashville, Tennessee,
March 1988. 相似文献

Capture-recapture studies and analyses have become an important tool for the study of bird populations. One reason for the rapid advancement in this area has been the EURING conferences where population biologists and statisticians meet to review recent progress, identify areas that require further work, and work collaborately to solve real world problems. In this paper, we forecast the needs for future research in this area and review the recent conference to try and identify what questions are yet unsolved. This EURING conference was dedicated to Dr George Seber who was the author of a number of key papers and whose name is synonymous with 'The estimation of animal abundance and related parameter' (Seber, 1982). He has retired from working in this field. 相似文献

The authors describe Bayesian estimation for the parameters of the bivariate gamma distribution due to Kibble (1941). The density of this distribution can be written as a mixture, which allows for a simple data augmentation scheme. The authors propose a Markov chain Monte Carlo algorithm to facilitate estimation. They show that the resulting chain is geometrically ergodic, and thus a regenerative sampling procedure is applicable, which allows for estimation of the standard errors of the ergodic means. They develop Bayesian hypothesis testing procedures to test both the dependence hypothesis of the two variables and the hypothesis of equal means. They also propose a reversible jump Markov chain Monte Carlo algorithm to carry out the model selection problem. Finally, they use sets of real and simulated data to illustrate their methodology. 相似文献

The impact of gender on gambling attitudes and behavior 总被引:3,自引:0,他引:3
H. Elaine Lindgren George A. Youngs Jr. Thomas D. McDonald Daniel J. Klenow Eldon C. Schriner 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》1987,3(3):155-167
Researchers have often attributed the consistent relation of gender and gambling behavior to gender role socialization. If they are correct, gender should affect different sets of gambling attitudes in a manner consistent with at least three aspects of gender role socialization: a double standard of morality, a guardian of the hearth role for women, and a dualism of orientations. A survey measuring gambling attitudes and behavior was sent to a sample of residents in North Dakota after legalization of several games of chance (e.g., blackjack). Gender affects behavior but only some of the specified attitudes. These mixed results may reflect changes in gender role socialization and the increasing legalization of gambling. 相似文献

Using data collected in Athens, Greece in the spring of 1977, an effort was made to test the relationship between several objective socioeconomic indicators and subjective class perceptions and political attitudes. Our main concern was the effect of subjective class awareness and consciousness on selected political issues (pro-Western foreign policy, civil liberties, and economic conservatism) and voting. Our findings show that class and socioeconomic variables tend to be stronger predictors of socio-political attitudes than are status indicators. In addition, subjective perceptions of class (particularly capitalist political influence and limited societal opportunity), father's politics, and age are major explanatory variables for political attitudes and the way people perceive national and international issues. Perception that the upper class benefits most from clientelism was related to voting and economic conservatism. Working-class consciousness was important in explaining voting in 1977. Our research strategy suggests that for the future we should broaden the study of class consciousness and awareness by viewing it as multidimensional and including measurements based on both closed- and open-ended questions. 相似文献
