PRACTICAL SIGNIFICANCE OF ITEM MISFIT AND ITS MANIFESTATIONS IN CONSTRUCTS ASSESSED IN LARGE-SCALE STUDIES

Abstract When scaling psychological tests with methods of item response theory it is necessary to investigate to what extent the responses correspond to the model predictions.In addition to the statistical evaluation of item misfit, the question arises as to its practical significance.Although item removal is undesirable for several reasons, its pr

The Arabidopsis LSD1 and LOL1 proteins both contain three conserved zinc finger domains and have antagonistic effects on plant programmed cell death (PCD).In this study, a rice (Oryza sativa) functional homolog of LSD1, designated OsLSD1, was identified.The expression of OsLSD1 was light-induced or dark-suppressed.Overexpression of OsLSD1 driven by
