Measurement invariance of the center for epidemiological studies depression scale (CES-D) among chinese and dutch elderly

, 2011
Background: Although previous studies using non-elderly groups have assessed the factorial invariance of the Center for Epidemiological Studies Depression Scale (CES-D) across different groups with the same social-cultural backgrounds, few studies have ...

Operando Tracking of Oxygen‐Vacancy Dynamics and Negative Capacitance in Ca‐Doped BiFeO3

Advanced Functional Materials, EarlyView.
Operando electrochemical impedance spectroscopy, combined with electrocoloration, enables a direct correlation between real‐space ionic redistribution and the corresponding frequency‐domain electrical response. In lateral Ca‐doped BiFeO3 devices, time‐resolved impedance snapshots capture the evolution from bulk‐dominated mixed conduction to an ...

A large-scale empirical investigation of measurement invariance decisions under multiple-group item response theory and multiple-group confirmatory factor analysis

Frontiers in Education
Measurement invariance (MI) testing is essential for ensuring valid cross-group comparisons in international large-scale assessments (ILSA). There are two major frameworks for establishing MI: multiple-group confirmatory factor analysis (MGCFA) and ...

Two Coexisting Pathways to Volatility in Valence‐Change Memory Devices

Advanced Functional Materials, EarlyView.
Volatile VCM‐type memristive devices exhibit current relaxation after resistive switching, but their microscopic origin remains debated. Using pulsed measurements and a new Tunnel‐DLTS approach on Pt/SrTiO3/Nb:SrTiO3 devices, we show that post‐SET volatility is predominantly ionic, while electronic contributions—arising from quasi‐Fermi‐level ...

Binary‐to‐Ternary Reconfigurable Transistors Using Plasma‐Assisted MoS2

Advanced Functional Materials, EarlyView.
A binary‐to‐ternary reconfigurable transistor is demonstrated using a dual‐gated molybdenum disulfide homojunction with localized O2 plasma treatment. The device exhibits on/intermediate and intermediate/off current ratios of 102 and 104, respectively, and the intermediate state is electrically tunable in the ternary mode.

Score-based tests of measurement invariance: Use in practice

Frontiers in Psychology, 2014
In this paper, we consider a family of recently-proposed measurement invariance tests that are based on the scores of a fitted model. This family can be used to test for measurement invariance w.r.t.

High‐Throughput Discovery of Quantum Frustrated Materials

Advanced Functional Materials, EarlyView.
Physics‐guided discovery of frustrated kagome and triangular magnets. ABSTRACT Geometrical frustration provides a fertile platform for realizing exotic quantum phases such as spin liquids, yet, the predictive identification of frustrated magnets remains limited.

Measurement invariance of the strength of motivation for medical school: a multi-group confirmatory factor analysis

BMC Medical Education, 2017
Background The Strength of Motivation for Medical School-Revised (SMMS-R) questionnaire measures students’ motivation for studying medicine. It includes three subscales: ‘willingness to sacrifice’, ‘readiness to start’, and ‘persistence’.
