Feasibility of a bilateral 4000–6000 Hz notch as a phenotype for genetic association analysis 2015 18 Objective: Noise-induced hearing loss (NIHL) is a worldwide health problem and a growing concern among young people. Although some people appear to be more susceptible to NIHL, genetic association studies lack a specific phenotype. We tested the feas...
Fitness Effects of Floral Plasticity and Thermoregulation in a Thermally Changing Environment 2012 331 To better understand the evolution of phenotypic plasticity and thermoregulation and their potential value for ectotherms in the face of global warming, we conducted field experiments to measure their effects on fitness and their association with rep...
Floral Reflectance, Color, and Thermoregulation: What Really Explains Geographic Variation in Thermal Acclimation Ability of Ectotherms? 2010 1093 Adaptive phenotypic plasticity in thermally sensitive traits, that is, thermal acclimation, generally increases with increasing latitude and altitude. The presumed explanation is that high-latitude/ altitude organisms have evolved greater acclimat...
Global sourcing shifts in the U.S. textile and apparel industry: a cluster analysis 2005 117 Globalization of the U.S. textile and apparel industry has been significantly spurred in the last decade by trade agreements such as the North American Free Trade Agreement (NAFTA), and the Caribbean Basin Initiative (CBI). In terms of the U.S. texti...
Histological Alterations in Male A/J Mice Following Nose-Only Exposure to Tobacco Smoke 2008 48 The incidence and multiplicity of grossly observed and microscopic lesions of the respiratory tract of A/J mice exposed nose-only to mainstream smoke (50, 200, or 400 mg total particulate matter/m3 from 2R4F cigarettes) was compared to those of filte...
An Improvement to the Aligned Rank Statistic for Two-factor Analysis of Variance 2005 60 We modify the nonparametric method of Brunner, Dette and Munk (1997) by applying their method to the aligned ranks of the data. We compare this new approach to three other rank tests: the F-test applied to the ranks of the date, the approximate F-tes...
JMASM8: Using SAS To Perform Two-Way Analysis Of Variance Under Variance Heterogeneity 2005 44 We present SAS code to implement the method proposed by Brunner et al. (1997) for performing two-way analysis of variance under variance heterogeneity.
A Method for Determining Equivalence in Industrial Applications 2002 38 This article considers the problem of determining whether the results of measurements at two different measurement times are equivalent. Quite often in an industrial quality assurance experiment, the goal is to provide evidence of equivalence, rather...
Multiple Plantago Species (Plantaginaceae) Modify Floral Reflectance and Color in Response to Thermal Change 2013 154 • Premise of the study: Understanding how plant reproduction responds to temperature has become increasingly important because of global climate change. Temperature-sensitive plasticity in floral reflectance is likely involved in some of these respon...
Nearly exact tests in factorial experiments using the aligned rank transform 1999 42 A procedure is studied that uses rank-transformed data to perform exact and estimated exact tests, which is an alternative to the commonly used F-ratio test procedure. First, a common parametric test statistic is computed using rank-transformed data,...
