We examined different model specifications to detect the presence of preference heterogeneity in a mode choice context. The specification that worked best allows for both systematic and random variations in tastes, with parameters obtained at the individual level using Bayesian methods. Subjective values of travel time (SVT) and expected individual compensated variation were derived and aggrega...
BACKGROUND Better understanding the etiology-specific incidence of severe acute respiratory infections (SARIs) in resource-poor, rural settings will help further develop and prioritize prevention strategies. To address this gap in knowledge, we conducted a longitudinal study to estimate the incidence of SARIs among children in rural Bangladesh. METHODS During June through October 2010, we fol...
PURPOSE To evaluate the minimum number of visual field (VF) tests required to precisely predict future VF results using ordinary least squares linear regression (OLSLR), quadratic regression, exponential regression, logistic regression, and M-estimator robust regression model. METHODS Series of 15 VFs (Humphrey Field Analyzer 24-2 SITA standard) were analyzed from 247 eyes of 155 open-angle g...
In traditional economic models, individual utility depends only on absolute consumption. These models lie at the heart of claims that pursuit of individual self-interest promotes aggregate welfare. Recent years have seen renewed interest in economic models in which individual utility depends not only on absolute consumption, but also on relative consumption. In contrast to traditional models, t...
We describe a compact laser wavelength measuring instrument based on a small diffraction grating and a consumer-grade webcam. With just 1 pW of optical power, the instrument achieves absolute accuracy of 0.7 pm, sufficient to resolve individual hyperfine transitions of the rubidium absorption spectrum. Unlike interferometric wavemeters, the instrument clearly reveals multimode laser operation,...

Whether poor single mothers move in response to welfare benefits has important implications for social policy in a federal system. Many scholars claim that welfare does not affect migration. These claims are not definitive, however, because the models underlying them rely on problematic assumptions and do not adequately control for nonwelfare determinants of migration. I address these shortcomi...
Nonlinear integration of sensory responses in the rat barrel cortex: an intracellular study in vivo.
To study integration of converging sensory inputs on single cortical neurons, we performed intracellular recordings in vivo in the barrel cortex of the barbiturate-anesthetized rat. We deflected the principal whisker (PW) for each cell either alone or preceded (at 20, 50, and 100 msec) by the deflection of a small number of remote whiskers (RWs) far from the PW. The synaptic responses to both t...
a 7×7 complete diallel cross experiment was performed to study the genetic relationships of grain yield and some agronomic traits in rice. analysis of variance showed significant differences among genotypes for all traits. results of correlation analysis showed that rice grain yield was positively and significantly correlated with by (rp = 0.81, rg =0.55), hi (rp =0.35, rg =0.79), np (rp = 0.80...
