Estimation of Standard Error, Linking Error, and Total Error for Robust and Nonrobust Linking Methods in the Two-Parameter Logistic Model

Stats
The two-parameter logistic (2PL) item response theory model is a statistical model for analyzing multivariate binary data. In this article, two groups are brought onto a common metric using the 2PL model using linking methods. The linking methods of mean–

A Group Fit Statistic for the Multilevel Item Response Model

Journal of Educational Measurement, Volume 63, Issue 1, Spring 2026.
Abstract Aberrant behaviors among test‐takers in large‐scale assessments are often more prevalent within specific groups or testing sites. While various techniques have been developed to detect individual‐level test‐takers' aberrant behaviors, research in detecting those behaviors at the group level is rare. We propose a group fit statistic lz2$ l_{z2}$

Improving Ability Estimation Accuracy for Automated Item Generated Forms under Multistage Testing

Journal of Educational Measurement, Volume 63, Issue 1, Spring 2026.
Abstract The emergence of automated item generation (AIG) techniques has intensified discussions around their application in assessment development. Some testing companies have already begun developing software to construct exams using AIG. However, the current literature offers limited insights into the characteristics of items generated through AIG ...

Development and Cross‐Cultural Validation of the Vietnamese Version of the Disaster Prevention Consciousness Scale: A Cross‐Sectional Study

Health Science Reports, Volume 9, Issue 1, January 2026.
ABSTRACT Background and Aims The Japanese Disaster Prevention Consciousness Scale (J‐DPCS) addresses all natural disasters, making it more adaptable to foreign populations. However, certain items in the scale refer to disaster preparedness measures which may not be emphasized in countries where infrastructure development for disaster prevention is less

Uniform Circular Array Antenna for Dual‐Mode Orbital Angular Momentum Generation at 6 GHz

International Journal of RF and Microwave Computer-Aided Engineering, Volume 2026, Issue 1, 2026.
Orbital angular momentum (OAM) antennas have recently attracted attention for their potential to enhance communication capacity and and robustness against interference. However, most existing designs rely on complex multilayer feed structures. This work presents a compact, single‐layer, series‐fed dual‐mode OAM antenna composed of four patches arranged

SIMEX-Based and Analytical Bias Corrections in Stocking–Lord Linking

Analytics
Stocking–Lord (SL) linking is a popular linking method for group comparisons based on dichotomous item responses. This article proposes a bias correction technique based on the simulation extrapolation (SIMEX) method for SL linking in the 2PL model in ...

Hyper‐Areal‐Capacity Dry Electrodes (22.6 mAh cm−2) Enabled by Electron Beam‐Induced Functionalization of Fibrillated PTFE for High‐Energy‐Density Li‐ion Batteries (>400 Wh kg−1)

Advanced Energy Materials, Volume 15, Issue 47, December 16, 2025.
The electron beam (EB) irradiation on dry‐processed electrode enhances the electrolyte wettability by oxidizing the intrinsic super‐hydrophobic nature of polytetrafluoroethylene polymeric binders. Thus, enhancing interfacial Li+ transport, the integration of EB irradiation into dry electrodes provides a scalable, solvent‐free route to boost electrode ...

Exploring the Role of Response Time in Item Response Theory: Rethinking the PISA 2022 Creative Thinking Assessment

The Journal of Creative Behavior, Volume 59, Issue 4, December 2025.
ABSTRACT This article explores the potential of response time‐item response theory (RT‐IRT) models to enhance creative thinking (CT) measurement in Programme for International Student Assessment (PISA) 2022, which employs traditional IRT models (2PL and generalized partial credit) excluding response time (RT).
