A field experiment was conducted to test the self-perception explanation of the "foot-in-the-door" phenomenon of increased compliance with a substantial request after prior compliance with a smaller demand. In this study, some subjects were first approached with a small request (answer 8 questions in a telephone survey) the size of which was virtually(More)
We demonstrated a general strategy for detecting motives that people wish to conceal. The strategy consists of having people choose between two alternatives, one of which happens to satisfy the motive. By counterbalancing which one does so, it is possible to distill the motive by examining the pattern of choices that people make. The motive used in the(More)
BACKGROUND Rare disease information sources are incompletely and inconsistently cross-referenced to one another, making it difficult for information seekers to navigate across them. The development of such cross-references established manually by experts is generally labor intensive and costly. OBJECTIVES To develop an automatic mapping between two of the(More)
A major challenge in traffic-related air pollution exposure studies is the lack of information regarding pollutant exposure characterization. Air quality modeling can provide spatially and temporally varying exposure estimates for examining relationships between traffic-related air pollutants and adverse health outcomes. A hybrid air quality modeling(More)
OBJECTIVE Approximately one-third of the adult U.S. population has the metabolic syndrome. Its prevalence is the highest among Hispanic adults, but variation by Hispanic/Latino background is unknown. Our objective was to quantify the prevalence of the metabolic syndrome among men and women 18-74 years of age of diverse Hispanic/Latino background. RESEARCH(More)
This work describes a methodology for modeling the impact of traffic-generated air pollutants in an urban area. This methodology presented here utilizes road network geometry, traffic volume, temporal allocation factors, fleet mixes, and emission factors to provide critical modeling inputs. These inputs, assembled from a variety of sources, are combined(More)
BACKGROUND Heart failure is sometimes incorrectly listed as the underlying cause of death (UCD) on death certificates, thus compromising the accuracy and comparability of mortality statistics. Statistical redistribution of the UCD has been used to examine the effect of misclassification of the UCD attributed to heart failure, but sex- and race-specific(More)
