Markov Chains
Markov chains are central to the understanding of random processes. This is not only because they pervade the applications of random processes, but also because one can calculat...

The Persistence and Transfer of Learning in Industrial Settings
The persistence of learning within organizations and the transfer of learning across organizations are examined on data collected from multiple organizations. Results indicate t...
Being Inconsistent About Consistency: When Coefficient Alpha Does and Doesn't Matter
One of the central tenets of classical test theory is that scales should have a high degree of internal consistency, as evidenced by Cronbach's a, the mean interitem correlation...
Teacher's Corner: Testing Measurement Invariance of Second-Order Factor Models
We illustrate testing measurement invariance in a second-order factor model using a quality of life dataset (n = 924). Measurement invariance was tested across 2 groups at a set...
Numerical Applications of a Formalism for Geophysical Inverse Problems
A gross datum of the Earth is a single measurable number describing some property of the whole Earth, such as mass, moment of inertia, or the frequency of oscillation of some id...
Sleep-Disordered Breathing in Community-Dwelling Elderly
These are the final results of a survey of sleep-disordered breathing, which examined objective and subjective information from a large randomly selected elderly sample. We rand...
Applying Convolutional Neural Networks concepts to hybrid NN-HMM model for speech recognition
Convolutional Neural Networks (CNN) have showed success in achieving translation invariance for many image processing tasks. The success is largely attributed to the use of loca...
Management of Lung Nodules Detected by Volume CT Scanning
Among subjects at high risk for lung cancer who were screened in three rounds of CT scanning and in whom noncalcified pulmonary nodules were evaluated according to volume and vo...
Survey Questions: Handcrafting the Standardized Questionnaire
This book reviews the experimental literature on how survey questions behave as well as the lore of professional experience and culls from them those guiding principles and spec...
Smooth Skyride through a Rough Skyline: Bayesian Coalescent-Based Inference of Population Dynamics
Kingman's coalescent process opens the door for estimation of population genetics model parameters from molecular sequences. One paramount parameter of interest is the effective...
Discriminant validation of measures of job satisfaction, job involvement, and organizational commitment.
Discriminant validity of measures of job satisfaction, job involvement, and organizational commitment was empirically evaluated using data collected from a sample of 577 full-ti...
A natural antisense transcript regulates Zeb2/Sip1 gene expression during Snail1-induced epithelial–mesenchymal transition
Expression of Snail1 in epithelial cells triggers an epithelial–mesenchymal transition (EMT). Here, we demonstrate that the synthesis of Zeb2, a transcriptional repressor of E-c...
