OBJECTIVES Examine the contribution of sleep problems and indicators of inadequate sleep to psychopathology among children after accounting for shared risk and comorbid psychopathology. METHODS Secondary analyses of cross-sectional data on 4- to 11-year-old (N = 1,550) children without chronic illness or developmental delay or disability. Parents provided information about sleep problems, ind...

A. C. Littleton famously described accounting as “relative and progressive”. However, in recent historical accounting research, there has been increasing hesitation in describing accounting as “progressing”. This is largely because “progress” implies a degree not only of change but also of improvement, and historical accounting researchers, influenced by social science conventions, often regard...

How to relate two blocks of variables? Partial least squares Analysis two-block pls u, v u'u = v'v = 1 Low-dimensional representation of the pattern of correlations/ covariances between two blocks of variables: A second dimension can be computed as directions orthogonal to the first ones, accounting for the second most correlation/covariance. A direction in each of the two data spaces, for whic...

A geophysical seismic survey was conducted in the summer of 2001 off the northeastern coast of Sakhalin Island, Russia. The area of seismic exploration was immediately adjacent to the Piltun feeding grounds of the endangered western gray whale (Eschrichtius robustus). This study investigates relative abundance, behavior, and movement patterns of gray whales in relation to occurrence and proximi...

In this paper, the authors analyze product attributes and consumer characteristics in an international service selection decision. Previous work has focused on main effects without exploring the significance of interaction or individual heterogeneity effects. Using conjoint and ordered probit analyses, we find that including interaction and respondent specific dummy variables alters the impacts...

We extend the random permutation model to obtain the best linear unbiased estimator of a finite population mean accounting for auxiliary variables under simple random sampling without replacement (SRS) or stratified SRS. The proposed method provides a systematic design-based justification for well-known results involving common estimators derived under minimal assumptions that do not require sp...

In its Exposure Draft, "Accounting for Stock-based Compensation," FASB proposes that either the Black-Scholes or binomial option pricing model be used to expense employee stock options, and that the value of these options be measured on their grant date with typically modest ex-post adjustment. This brings the accounting profession squarely up against the Scylla of imposing too narrow a set rul...
