This study found mixed support for the hypothesis that the difference in criterion-related validity between unstructured and structured employment interviews is due solely to the greater reliability of structured interviews. Using data from prior meta-analyses, this hypothesis was tested in 4 data sets by using standard psychometric procedures to remove the effects of measurement error in inter...

The standard error of equating is a useful index to quantify the amount of equating error. It is the standard deviation of equated scores over replications of an equating procedure in samples from a population or populations of examines. The current study estimates the SE of item response theory true score equating in the Nonequivalent Groups with Anchor Test design using simulations. Specifica...

Turning to Karl Jaspers’s 1937 lectures, later published as Philosophy of Existence, this paper examines what might be meant by the colloquial expression “spiritual but not religious”. In doing so, it is argued that while critique organized religion mostly hits mark, critiques religion—as represented here Existenzphilosophie—fail undermine a form genuine spirituality grounded in faith revealed ...

MOTIVATION For genetic studies, statistically significant variants explain far less trait variance than 'sub-threshold' association signals. To dimension follow-up studies, researchers need to accurately estimate 'true' effect sizes at each SNP, e.g. the true mean of odds ratios (ORs)/regression coefficients (RRs) or Z-score noncentralities. Naïve estimates of effect sizes incur winner's curse ...
