Enhancing the Validity and Cross-cultural Comparability of Measurement in Survey Research
(Cambridge University Press, 2004)We address two long-standing survey research problems: measuring complicated concepts, such as political freedom and efficacy, that researchers define best with reference to examples; and what to do when respondents interpret ... -
The ENIGMA Consortium: large-scale collaborative analyses of neuroimaging and genetic data
(Springer US, 2014)The Enhancing NeuroImaging Genetics through Meta-Analysis (ENIGMA) Consortium is a collaborative network of researchers working together on a range of large-scale studies that integrate data from 70 institutions worldwide. ... -
An enigma in estimates of the Earth's dynamic ellipticity
(Oxford University Press, 2012)The precession and obliquity frequencies of the Earth’s rotational motion are functions of the dynamic ellipticity of the Earth’s gravitational figure, and this connection has provided a novel bridge between studies of ... -
The Enigma of the Pseudogap Phase of the Cuprate Superconductors
(2015)The last few years have seen significant experimental progress in characterizing the copper-based hole-doped high temperature superconductors in the regime of low hole density, p. Quantum oscillations, NMR, X-ray, and STM ... -
The Enigmatic Planctomycetes May Hold a Key to the Origins of Methanogenesis and Methylotrophy
(Oxford University Press, 2004)Methanogenesis and methane oxidation are the major biological processes affecting the global cycling of the powerful greenhouse gas methane. To carry out the two alternative bioconversions, Nature has cleverly recycled key ... -
Enjoying the Quiet Life? Corporate Governance and Managerial Preferences
(University of Chicago Press, 2003)Much of our understanding of corporations builds on the idea that managers, when they are not closely monitored, will pursue goals that are not in shareholders’ interests. But what goals would managers pursue? This paper ... -
Enriched Basalts at Segment Centers: The Lucky Strike (37°17′N) and Menez Gwen (37°50′N) Segments of the Mid‐Atlantic Ridge
(American Geophysical Union, 2011)Basalts from the Mid-Atlantic Ridge change progressively in composition with increasing distance from the Azores platform. Study of the Lucky Strike and Menez Gwen segments reveals much complexity in the gradient. Both ... -
Enriched Iron(III)-Reducing Bacterial Communities are Shaped by Carbon Substrate and Iron Oxide Mineralogy
(Frontiers Media S.A., 2012)Iron (Fe) oxides exist in a spectrum of structures in the environment, with ferrihydrite widely considered the most bioavailable phase. Yet, ferrihydrite is unstable and rapidly transforms to more crystalline Fe(III) oxides ... -
Enrichment of Reticulocytes from Whole Blood using Aqueous Multiphase Systems of Polymers
(Wiley-Blackwell, 2014)This paper demonstrates the enrichment of reticulocytes by centrifuging whole blood through aqueous multiphase systems (AMPSs)—immiscible phases of solutions of polymers that form step-gradients in density. The interfaces ... -
Enrichment of the Intergalactic Medium by Radiation Pressure Driven Dust Efflux
(American Astronomical Society, 2000)The presence of metals in hot cluster gas and in Ly absorbers, as well as the mass-metallicity relation of observed galaxies, suggest that galaxies lose a significant fraction of their metals to the intergalactic medium ... -

Enrollee Mix, Treatment Intensity, and Cost in Competing Indemnity and HMO Plans
(Elsevier, 2003)Why do indemnity insurance plans cost substantially more per capita—77% more in our study—than HMOs? We answer this question using data from a large organization’s insurance pool, covering 215,000 lives. We decompose cost ... -
The ensemble folding kinetics of the FBP28 WW domain revealed by an all-atom Monte Carlo simulation in a knowledge-based potential
(Wiley-Blackwell, 2011)In this work, we apply a detailed all-atom model with a transferable knowledge-based potential to study the folding kinetics of Formin-Binding protein, FBP28, which is a canonical three-stranded β-sheet WW domain. Replica ... -
Ensemble Learning for Reectometry
(2010)In “Blind Reflectometry” (Romeiro and Zickler, 2010 [3]) we describe a variational Bayesian approach to inferring material properties (BRDF) from a single image of a known shape under unknown, real-world illumination. This ... -
Ensemble Quantum Computing by Nuclear Magnetic Resonance Spectroscopy
(1996)A quantum computer (QC) can operate in parallel on all its possible inputs at once, but the amount of information that can be extracted from the result is limited by the phenomenon of wave function collapse. We present a ... -
Ensemble-Adjusted p Values
(American Psychological Association, 1983)When contrasts or other tests of significance can be ordered according to their importance, adjusted p values can be computed that permit greater power to be brought to bear on contrasts of greater interest or importance. ... -
Ensembles of engineered cardiac tissues for physiological and pharmacological study: Heart on a chip
(Royal Society of Chemistry (RSC), 2011)Traditionally, muscle physiology experiments require multiple tissue samples to obtain morphometric, electrophysiological, and contractility data. Furthermore, these experiments are commonly completed one at a time on cover ... -
ENSO’s Phase Locking to the Seasonal Cycle in the Fast-SST, Fast-Wave, and Mixed-Mode Regimes
(American Meteorological Society, 2000)The physical mechanism underlying ENSO’s phase locking to the seasonal cycle is examined in three parameter regimes: the fast-SST limit, the fast-wave limit, and the mixed SST–wave dynamics regime. The seasonal cycle is ... -
Ensuring the Data-Rich Future of the Social Sciences
(American Association for the Advancement of Science (AAAS), 2011)Massive increases in the availability of informative social science data are making dramatic progress possible in analyzing, understanding, and addressing many major societal problems. Yet the same forces pose severe ...
