Co‐flowering with congeners does not affect buzz‐pollinator specialization and pollination performance in Rhexia mariana, but does affect floral trait variance

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Pollinator‐mediated plant‐plant interactions may be negative (i.e., competition, reproductive interference) or positive (i.e., facilitation). Especially when co‐flowering with close relatives (e.g., congeners), negative interactions through reproductive interference may be strong and result in floral trait divergence and increased ...

Longitudinal Associations of Job Demand‐Control Characteristics With Objective and Subjective Cognitive Outcomes in Older Workers: The Health and Retirement Study

open access: yesAmerican Journal of Industrial Medicine, EarlyView.
ABSTRACT Background The job demand‐control (JDC) psychosocial work model has demonstrated effects on objective cognitive performance, but its association with subjective memory is still poorly understood. We examined longitudinal associations of JDC characteristics with objective (general cognitive function/episodic memory) and subjective (perceived ...

Bootstrap Estimation for GEE Models [PDF]

open access: yesKorean Journal of Applied Statistics, 2011
Bootstrap is a resampling technique to find an estimate of parameters or to evaluate the estimate. This technique has been used in estimating parameters in linear model(LM) and generalized linear model(GLM). In this paper, we explore the possibility of applying Bootstrapping Residuals, Pairs, and an Estimating Equation that are most widely used in LM ...
