Virtually everything we own was transported by truck at some point. Around 3.5 million truck drivers haul almost 71% of U.S. freight. To ensure the safety of our roadways, the U.S. government requires all drivers to pass urinalysis drug screens. However, urinalysis drug screens are easily thwarted and some trucking companies use hair drug screens, a more stringent test. This research examines trucking industry data and finds about 300,000 truck drivers would be removed from their positions if forced to pass a hair drug test. Hair testing opponents argue that the test is biased against ethnic minority groups. Comparing urine and hair pass/fail rates for various ethnic groups, our results indicate ethnic groups are significantly different irrespective of testing procedure. Factors other than testing method seem to underlie ethnic group pass/fail rate differences.
Examines the perceptions and preferences of fragrances by females. The sample was taken from nine cities across three continents. Of the two major fragrance concepts examined, unisex fragrances have been introduced, with only about half the respondents in the nine cities (six countries) surveyed in this study being familiar with the concept. Respondents assessed the effects of ten factors on the fragrance decisions. The joint effects of ten surveyed factors show major differences between samples as stratified by area, with some consistency among the top factors, as supported by ANOVA and MANOVA analysis. Chi-Square analysis of unisex and``same-name'' fragrances indicated significant differences in four of six variables. The ten surveyed factors werè`s cent, European fragrance, price, brand (purchased for self), brand (purchased as gift), mood, season, free items with purchase, container, and color.''``Scent, price, brand and mood'' were the dominant variables. Significant differences existed between the respondents in the three major geographic areas, USA, Europe and Asia for seven of the ten factors, i.e. European fragrance, price, brand purchased as a gift, mood, season, container, and color.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
