The information matrix test with bootstrap-based covariance matrix estimation. [PDF]
We propose an information matrix test in which the covariance matrix of the vector of indicators is estimated using the parametric bootstrap. Monte Carlo results and heuristic arguments show that its small sample performance is comparable with that of ...

The Effect of Chess on Standardized Test Score Gains
SAGE Open, 2019 The study compares the standardized test performance of “chess kids” versus their peers. The comparison of score gains to non-chess peers (same grade and same academic percentile) attempts to eliminate the chicken-and-egg issue that often muddles this ...

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

The Roma/non-Roma Test Score Gap in Hungary [PDF]
This paper documents and decomposes the test score gap between Roma and non-Roma 8th graders in Hungary in 2006. Our data connect national standardized test scores to an individual panel survey with detailed data on ethnicity and family background.

Test Score (SI5): Assess Diagnostic of Sacroiliac Joint Dysfunction
Global Spine Journal, 2016 Objective The sacroiliac joint dysfunction is a known cause of low back pain. We think that a test score (SI5) may be performed to assess diagnostic utility of clinical signs of sacroiliac joint dysfunction.

FEBS Letters, EarlyView.Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Item-Score Reliability as a Selection Tool in Test Construction
Frontiers in Psychology, 2019 This study investigates the usefulness of item-score reliability as a criterion for item selection in test construction. Methods MS, λ6, and CA were investigated as item-assessment methods in item selection and compared to the corrected item-total ...

FEBS Letters, EarlyView.This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

A Score Test for Individual Heteroscedasticity in a One-way Error Components Model [PDF]
The purpose of this paper is to derive a Rao's efficient score statistic for testing for heteroscedasticity in an error components model with only individual effects. We assume that the individual effect exists and therefore do not test for it.
