Is pseudo-equivalent groups equating via minimum discriminant information adjustment effective? Evidence from simulation and real data

Frontiers in Education
The traditional way to linking different forms of test typically uses common (or randomly equivalent) examinees or items. When common examinees or items are unavailable due to test properties or administrative restrictions, equating with pseudo ...

Phase Angle as an Early Functional Biomarker of Cancer‐Related Fatigue in Pediatric Oncology: A Prospective Longitudinal Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric cancer remains a leading cause of morbidity and mortality worldwide, particularly in low‐and middle‐income countries. Cancer treatment may impair nutritional status, alter body composition, and exacerbate cancer‐related fatigue (CRF).

Determining Parental Factors for Clinical Trial Attrition in Pediatric Acute Lymphoblastic Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background/Objectives Despite high enrollment rates on Children's Oncology Group (COG) protocols, attrition after initial consent is challenging, introducing bias and prolonging trial completion. While adult oncology literature has identified predictors of withdrawal, little is known about caregiver decision‐making for child participation in ...

Equational axioms of test algebra [PDF]

, 1998
We have axiomatized test algebra equations and achieved a finite equational axiomatization relative to Kleene algebra. The previous section showed that the Kleene algebra component cannot be replaced by a finite set of test algebra equations.

A TEST OF THE NULL EQUATION FOR FUNCTIONAL ANTAGONISM [PDF]

British Journal of Pharmacology, 1981
The quantitative model for functional antagonism and synergism has been tested by studying its ability to fit data obtained from the functional antagonism of (−)‐isoprenaline by muscarinic agonists on guinea‐pig isolated atria. The general form of the null equation has been shown to fit the experimental curves satisfactorily.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Harmonizing the CBCL and SDQ ADHD scores by using linear equating, kernel equating, item response theory and machine learning methods

Frontiers in Psychology
IntroductionA problem that applied researchers and practitioners often face is the fact that different institutions within research consortia use different scales to evaluate the same construct which makes comparison of the results and pooling ...
