Reverse worded (RW) items are often used to reduce or eliminate acquiescence bias, but there is a rising concern about their harmful effects on the covariance structure of the scale. Therefore, results obtained via traditional covariance analyses may be distorted. This study examined the effect of the RW items on the factor structure of the abbreviated 18-item Need for Cognition (NFC) scale usi...

[1] Recently proposed ion-mediated nucleation theory suggests that the enhanced uptake of neutral polar molecules by the charged clusters as a result of dipole-charge interaction may be critical to the nucleation of particles in the atmosphere. A rigorous parameterization of the enhancement effect of dipole-charge interaction on the growth of charged clusters is presented and the important para...

In the past, the extended corresponding states approach to fluid property prediction has been restricted to Ž . non-polar fluids e.g., hydrocarbons and some common non-polar inorganics due to the lack of an accurate way to predict the required shape factors. In this work, a new predictive method to obtain shape factors for the Ž . extended corresponding states theory ECST has been developed whi...

The electric field of dissolved ions accounts for the narrow spike at zero frequency shift, with the polarization signature of a polar longitudinal collective mode, in the high resolution hyper-Rayleigh light scattering (HRS) spectrum for liquid water and other polar solvents. This peak in the HRS spectrum probes both the structure factor and the fluctuation time for the ion charge density in s...

Let B be an m × n (m ≥ n) complex (or real) matrix. It is known that there is a unique polar decomposition B = QH, where Q∗Q = I, the n× n identity matrix, and H is positive definite, provided that B has full column rank. If B is perturbed to B̃, how do the polar factors Q and H change? This question has been investigated quite extensively, but most work so far has been on how the perturbation c...
