Effects of 2000-2050 Global Change on Ozone Air Quality in the United States
(American Geophysical Union, 2008)We investigate the effects on U.S. ozone air quality from 2000–2050 global changes in climate and anthropogenic emissions of ozone precursors by using a global chemical transport model (GEOS-Chem) driven by meteorological ... -
Effects of 2000–2050 Changes in Climate and Emissions on Global Tropospheric Ozone and the Policy-Relevant Background Surface Ozone in the United States
(American Geophysical Union, 2008)We use a global chemical transport model (GEOS-Chem) driven by a general circulation model (NASA Goddard Institute for Space Studies GCM) to investigate the effects of 2000–2050 global change in climate and emissions (the ... -
The Effects of a Centralized Clearinghouse on Job Placement, Wages, and Hiring Practices
(University of Chicago Press, 2009)New gastroenterologists participated in a labor market clearinghouse (a "match") from 1986 through the late 1990’s, after which the match was abandoned. This provides an opportunity to study the effects of a match, by ... -
The Effects of a Stress-Dependent Mobility on Interfacial Stability
(Imperial College Press, 2000)A linear morphological stability analysis of a planar interface in interface reaction-controlled growth is presented. We allow the mobility of the interface to be a function of the elastic stress, and nd that the stress ... -
Effects of a Wind-Driven Gyre on Thermohaline Circulation Variability
(American Meteorological Society, 2004)A simplified model is used to study the possible effects of the horizontal upper-ocean wind-driven circulation (WDC) on the variability of the overturning meridional circulation driven by buoyancy fluxes. It is found that ... -
The Effects of Biogeography on Ant Diversity and Activity on the Boston Harbor Islands, Massachusetts, U.S.A.
(Public Library of Science, 2011)Many studies have examined how island biogeography affects diversity on the scale of island systems. In this study, we address how diversity varies over very short periods of time on individual islands. To do this, we ... -
Effects of cardioactive drugs on human induced pluripotent stem cell derived long QT syndrome cardiomyocytes
(Springer International Publishing, 2016)Human induced pluripotent stem cells (hiPSC) have enabled a major step forward in pathophysiologic studies of inherited diseases and may also prove to be valuable in in vitro drug testing. Long QT syndrome (LQTS), characterized ... -
Effects of China's Rural Insurance Scheme on Objective Measures of Health
(Public Library of Science, 2016)Background In 2003, the Chinese government established the New Cooperative Medical Scheme (NCMS) with the goal of improving health for the country’s 800 million mostly uninsured rural residents. Using new data on objective ... -
Effects of Contact-Line Pinning on the Adsorption of Nonspherical Colloids at Liquid Interfaces
The effects of contact-line pinning are well known in macroscopic systems but are only just beginning to be explored at the microscale in colloidal suspensions. We use digital holography to capture the fast three-dimensional ... -
Effects of contrastive accents on children’s discourse comprehension
(Springer Nature, 2016)What role do contrastive accents play in children’s discourse comprehension? By 6 years of age, children use contrastive accents during online comprehension to predict upcoming referents (Ito et al., 2014; Sekerina & ... -
Effects of Cortisol and Cocaine on Plasma Prolactin and Growth Hormone Levels in Cocaine-Dependent Volunteers
(Elsevier, 2005)In rodents, corticosterone (cortisol in humans) facilitates cocaine self-administration purportedly via enhancement of dopaminergic activity in the brain. This study sought to assess central dopaminergic effects of cortisol ... -
Effects of Disks on Gravitational Lensing by Spiral Galaxies
(American Astronomical Society, 1998)Gravitational lensing of a quasar by a spiral galaxy should often be accompanied by damped Ly alpha absorption and dust extinction due to the intervening gaseous disk. In nearly edge-on configurations, the surface mass ... -
Effects of Emotion on Memory Specificity in Young and Older Adults
(Gerontological Society of America, 2002)To examine how emotional content affects the amount of visual detail remembered, we had young and older adults study neutral, negative, and positive objects. At retrieval, they distinguished same (identical) from similar ... -
Effects of emotionally valenced working memory taxation on negative memories
(Elsevier BV, 2014)Background and objectives: Memories enter a labile state during recollection. Thus, memory changes that occur during recollection can affect future instances of its activation. Having subjects perform a secondary task that ... -
The Effects of Entry on Incumbent Innovation and Productivity
(MIT Press, 2009)How does firm entry affect innovation incentives in incumbent firms? Microdata suggest that there is heterogeneity across industries. Specifically, incumbent productivity growth and patenting is positively correlated with ... -
Effects of explicit atmospheric convection at high CO2
(National Academy of Sciences, 2014)The effect of clouds on climate remains the largest uncertainty in climate change predictions, due to the inability of global climate models (GCMs) to resolve essential small-scale cloud and convection processes. We compare ... -
The Effects of Exposure to Better Neighborhoods on Children: New Evidence from the Moving to Opportunity Experiment
(American Economic Association, 2016)The Moving to Opportunity (MTO) experiment offered randomly selected families housing vouchers to move from high-poverty housing projects to lower-poverty neighborhoods. We analyze MTO's impacts on children's long-term ... -
Effects of Flight Speed upon Muscle Activity in Hummingbirds
(The Company of Biologists, 2010)Hummingbirds have the smallest body size and highest wingbeat frequencies of all flying vertebrates, so they represent one endpoint for evaluating the effects of body size on sustained muscle function and flight performance. ... -
The Effects of Food Processing on Masticatory Performance and Its Implications for Hominid Cranio-dental Evolution
(John Wiley & Sons, 2007)A steady decrease in relative dental and facial size occurred during the evolution of the genus Homo. It is often hypothesized that this reduction was made possible by, or was an adaptation for chewing food that was cooked ... -
Effects of Forming Gas Anneal on Ultrathin InGaAs Nanowire Metal-Oxide-Semiconductor Field-Effect Transistors
(American Institute of Physics, 2013)InGaAs gate-all-around metal-oxide-semiconductor field-effect transistors (MOSFETs) with 6 nm nanowire thickness have been experimentally demonstrated at sub-80 nm channel length. The effects of forming gas anneal (FGA) ...
