In recent years, considerable attention has been devoted to methods for analyzing longitudinal data. A review of some of the issues surrounding the use of regression analysis is undertaken as they relate to a study of the health effects of air pollution in a group of asthmatics. Daily diary recordings of hours with asthma symptoms are found to be positively related to the daily mean concentration of total reduced sulphur as well as to the daily intake of nonsteroidal drug medication. This finding is corroborated using three different statistical models. 相似文献

RESPONSE LATENCY VERSUS CERTAINTY AS INDEXES OF THE STRENGTH OF VOTING INTENTIONS IN A CATI SURVEY 总被引:3,自引:0,他引:3
This CATI study compares two measures of attitude strength,accessibility and certainty, for the purpose of predicting discrepanciesbetween voting intentions and voting behavior. Accessibilitywas indexed by response latency to a voting intention questionand certainty by a question about the finality of the votingintention. Logistic regression showed response latency to bea better predictor of discrepancies between voting intentionsand voting behavior than certainty. The theoretical implicationsof this finding as well as the practical implications of a methodfor measuring response latencies in CATI election studies arediscussed. 相似文献

We formulate a voting model for a legislature composed of two disjoint and cohesive subgroups. Each subgroup has a leader, and its cohesiveness is measured by the probability that a member votes the same way as the leader, which is presumed to be the same for all non-leader members within a subgroup. We examine the relative powers of the subgroups as a function of their sizes and cohesiveness. 相似文献

The thesis of this article is that sufficient and convincing research evidence has accumulated to indicate that a sixth stage of career development—career renewal—occurs for many people between the end of the establishment stage and the beginning of the maintenance stage. This article explains why a renewal stage was overlooked in the 1940s and 1950s, clarifies the meaning of renewal as it applies to career development, compares the transitions of men and women in their early 40s, and offers suggestions for the counseling of clients who are dealing with the task of career renewal. 相似文献

V. Kerry Smith 《Risk analysis》1986,6(3):325-334
The objective of this paper is to develop the ex ante perspective for benefit analysis with natural hazards. It defines an ex ante evaluation of the economic benefits that arise from policies designed to reduce either the risk of or the detrimental effects associated with a natural hazard. In the process the paper compares the ex ante and ex post perspectives and discusses the prospects for implementing the framework by measuring the valuation concepts that are developed. 相似文献
