A survey of factors contributing to accurate theoretical predictions of atomization energies and molecular structures.

Abstract: High level electronic structure predictions of thermochemical properties and molecular structure are capable of accuracy rivaling the very best experimental measurements as a result of rapid advances in hardware, software, and methodology. Despite the progress, real world limitations require practical approaches designed for handling general chemical systems that rely on composite strategies in which a single, intractable calculation is replaced by a series of smaller calculations. As typically implemented, these approaches produce a final, or “best,” estimate that is constructed from one major component, fine-tuned by multiple corrections that are assumed to be additive. Though individually much smaller than the original, unmanageable computational problem, these corrections are nonetheless extremely costly. This study presents a survey of the widely varying magnitude of the most important components contributing to the atomization energies and structures of 106 small molecules. It combines large Gaussia...

Development and Assessment of Short and Very Short Forms of the Infant Behavior Questionnaire–Revised

Abstract: Using data from parents of 761 infants from 6 independent samples, short (91 items, 14 scales) and very short (37 items, 3 broad scales) forms of the Infant Behavior Questionnaire-Revised (IBQ-R), a well-established caregiver report measure of temperament for infants aged 3 to 12 months, were developed. The forms were subsequently evaluated with data from 1,619 participants from 11 samples. Over 90% of Cronbach's alphas and part-whole correlations calculated for the short and very short form scales were greater than.70. Interparent agreement was nearly identical to that obtained with standard IBQ-R scales, averaging.41 and ranging from.06 to.76. Longitudinal stability over multiple time spans, and estimated retest reliability of the short form scales, were highly similar to those of standard forms, with estimated retest reliability averaging.72 and ranging from.54 to.93. Convergent and predictive validity of select short form scales were comparable to, but slightly lower, than those observed for standard IBQ-R scales. Recommendations for the use of the standard, short, and very short scales are discussed.
