[email protected] Abstract The past two decades have seen great progress in understanding the mechanisms of ecosystem stability in local ecological systems. There is, however, an urgent need to extend existing knowledge to larger spatial scales to match the scale of management and conservation. Here, we develop a general theoretical framework to study the stability and variability of ec...
BACKGROUND AND OBJECTIVES Despite increased emphasis on asking about intimate partner violence (IPV), little data exists on patient outcomes. We surveyed family physicians in New Hampshire and North Carolina to determine rates of asking about IPV, patient outcomes after disclosure, and changes in the doctor-patient relationship as a result of patient disclosure. METHODS Active members of the ...

Braun et al. discovered an error in the SAS code of their paper “Variability of Urinary Phthalate Metabolite and Bisphenol A Concentrations before and during Pregnancy” [Environ Health Perspect 120:739–745 (2012)]. The error resulted in the reported absolute concentrations of phthalate metabolites and BPA being approximately 50% higher. The authors mistakenly used the median value from the EART...
The September 2014 News article “Vaping and Health: What Do We Know about E-Cigarettes?” [Environ Health Perspect 122:A244–A249 (2014); http://dx.doi.org/10.1289/ehp.122-A244 ] has been revised to correct errors and clarify certain statements. The article incorrectly referred twice to e-cigarette emissions as “secondhand smoke.” However, e-cigarettes do not produce smoke; they produce vapor. In...
