|Fitness Effects of Floral Plasticity and Thermoregulation in a Thermally Changing Environment
||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?
||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
||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
||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
||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
||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
||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
||• 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
||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,...

||Objectives: To examine any association of necrotizing enterocolitis (NEC) and intestinal perforation (IP) in very low birth weight neonates with indomethacin treatment, cumulative dose or maximum plasma concentrations. Methods: This is a retrospectiv...
|Performing Two-Way Analysis of Variance Under Variance Heterogeneity
||Small sample properties of the method proposed by Brunner et al. (1997) for performing two-way analysis of variance are compared to those of the normal based ANOVA method for factorial arrangements. Different effect sizes, sample sizes, and error str...
|Poor long-term patient and graft survival after primary percutaneous coronary intervention for acute myocardial infarction due to saphenous vein graft occlusion
||Primary percutaneous coronary intervention (PCI) for ST segment elevation myocardial infarction (STEMI) due to saphenous vein graft (SVG) occlusion has been associated with poor procedural results and poor short-term outcomes, but long-term graft pat...
|SAS Program To Perform Analysis Of Factorial Experiments Using Aligned Ranks
||In situations when analysis of variance procedures are utilized, it is generally thought important that the assumptions associated with analysis of variance be fulfilled. Two assumptions that are often examined in the course of an analysis are normal...
