How social network heterogeneity facilitates lexical access and lexical prediction
Social networks Variability Lexical access
2017/8/30
People learn language from their social environment. As individuals differ in their social networks, they might be exposed to input with different lexical distributions, and these might influence thei...
HETEROGENEITY INDEX FOR THE ASSESSMENT OF RELATIONSHIP BETWEEN LAND USE PATTERN AND ROAD TRAFFIC CONGESTION IN APAPA-OWOROSHOKI EXPRESS WAY, LAGOS METROPOLIS
Traffic Congestion Land-Use Heterogeneity Index AHP
2017/7/12
The problem of urban mobility is complicated by traffic delay, resulting from poor planning, high population density and poor condition of roads within urban spaces. This study assessed traffic conges...
New constraints on shergottite petrogenesis from analysis of Pb isotopic compositional space: Implications for mantle heterogeneity and crustal assimilation on Mars
shergottite Pb isotopes Martian geochemistry crustal assimilation mantle heterogeneity
2017/4/10
Geochemical studies of shergottites (Martian basalts) based on Rb-Sr, Sm-Nd, and Lu-Hf isotopic systematics have
provided clues to understanding the geochemical evolution of the Martian mantle and id...
Quantitative,Directional Measurement of Electric Field Heterogeneity Within an Enzyme Active Site
Quantitative Directional Measurement Electric Field Heterogeneity Enzyme Active Site
2016/5/25
Extensive structural studies of enzymes have revealed that biological catalysis occurs within sequestered active site crevices, where reacting substrates are surrounded by an anisotropic and chemicall...
Antibody Evolution Constrains Conformational Heterogeneity by Tailoring Protein Dynamics
flexibility nonlinear spectroscopy fluorscein molecular recognition
2016/5/24
The evolution of proteins with novel function is thought to start from precursor proteins that are conformationally heterogeneous. The corresponding genes may be duplicated and then mutated to select ...
Semiparametric Bayesian Modeling of Income Volatility Heterogeneity
hierarchical Dirichlet process income volatility state-space models
2016/3/18
Research on income risk typically treats its proxy—income volatility, the expected magnitude of income changes—as if it were unchanged for an individual over time, the same for everyone at a point in ...
An Efficient Multi-Scale Segmentation for High-Resolution Remote Sensing Imagery Based on Statistical Region Growing and Minimum-Heterogeneity Rule
Multi-scale Segmentation High-Resolution Statistical Region Merging (SRM)
2015/12/17
Multi-scale segmentation is an essential step toward higher level image processing in remote sensing. This paper presents a new multi-scale segmentation method based on Statistical Region Merging (SRM...
EFFICIENT IV ESTIMATION FOR AUTOREGRESSIVE MODELSWITH CONDITIONAL HETEROGENEITY
AUTOREGRESSIVE CONDITIONAL HETEROGENEITY
2015/9/22
This paper analyzes autoregressive time series models where the errors are assumed to
be martingale difference sequences that satisfy an additional symmetry condition on their
fourth order mom...
Excess Capacity and Heterogeneity in the Fiscal Multiplier: Evidence from the Obama Stimulus Package
Capacity Heterogeneity
2015/9/21
We estimate local multipliers from the ARRA (Obama stimulus) bill using cross-county variation
in expenditure. We use within-state variation, and include other demographic controls as well
as a pred...
Resistivity and heterogeneity of Earth crust in an active tectonic region,Southern Tuscany (Italy)
crustal exploration magnetotellurics geothermal areas
2015/9/14
Southern Tuscany, belonging to the inner zone of the Northern Apennines, Italy, is an ideal laboratory for observing the physical features of the lithosphere and their evolution in tectonically active...
A GML SCHEMA MAPPING APPROACH TO OVERCOME SEMANTIC HETEROGENEITY IN GIS
Application Schema Mapping GIS interoperability Ontology
2015/8/28
With the increasing need of spatial data in various decision support systems, the access and sharing of geospatial data over the
Internet has become an important issue. But the underlying heterogenei...
Competitive Screening in Insurance Markets with Endogenous Wealth Heterogeneity
Insurance Markets Adverse Selection Multidimensional Screening
2015/7/31
We examine equilibria in competitive insurance markets with adverse selection when wealth differences arise endogenously from unobservable savings or labor supply decisions. The endogeneity of wealth ...
A Theory of Income Taxation under Multidimensional Skill Heterogeneity
Income Taxation Multidimensional Skill Heterogeneity
2015/7/31
We develop a unifying framework for optimal income taxation in multi-activity economies with general production technologies. Agents are characterized by an N-dimensional skill vector that captures in...
We use responses to survey questions in the 2010 Italian Survey of Household Income and Wealth
that ask consumers how much of an unexpected transitory income change they would consume. We
find tha...
Recent theoretical work has shown the importance of measuring microeconomic uncertainty for models of both general and partial equilibrium under imperfect insurance.
In this paper the assumption of i...
