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 ...

Switching Superconductivity with Uniaxial Strain in a high‐Tc${\rm T}_{c}$ Cuprate Superconductor

Advanced Functional Materials, EarlyView.
Uniaxial strain is demonstrated as a new scheme for a superconductivity switch. Exploiting the large strain‐induced Tc shift in a cuprate superconductor enables robust switching between superconducting and normal states over 100 cycles with only 0.1% strain.

Bistable Isochoric Chiral Metamaterials with Reprogrammable Multiaxial Responses

Advanced Functional Materials, EarlyView.
An isochoric bistable rotational unit cell enables in situ modification of internal contact conditions post‐fabrication, without altering the global envelope dimensions of the surrounding architecture. By selectively switching between open and closed states, the tessellated chiral metamaterial can reprogram its volumetric response, including bulk ...

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.

Gender measurement invariance of the learning burnout scale of undergraduates (LBSU) among Chinese undergraduates [PDF]

This study aimed to examine the measurement invariance of the Learning Burnout Scale of Undergraduates (LBSU) across gender, addressing a significant gap in the literature despite the scale’s widespread use in research.

Deformation‐Tolerant Functional Elastomer Overlayers for Haze‐Assisted Light Extraction and Color Conversion in Stretchable Mechanoluminescent Films

Advanced Functional Materials, EarlyView.
Functional elastomer overlayers are integrated onto stretchable ZnS:Cu‐PDMS mechanoluminescent films to regulate light after emission without modifying the emissive composite. NLC‐PU provides haze‐assisted light extraction to enhance green mechanoluminescence, while DCM‐NLC‐PU combines green‐to‐yellow‐orange color conversion with enhanced outward light

Orbital Engineering through Strain‐Induced Spin–Orbit–Lattice Coupling in Sr2FeReO6 Double Perovskites

Advanced Functional Materials, EarlyView.
Epitaxial strain drives oxygen‐octahedral reconfiguration in Sr2FeReO6 double‐perovskite thin films, inducing orbital‐selective reconstruction of Re 5d states through modified Fe–O–Re hybridization. This coupled lattice–orbital response enables magnetic easy‐axis reversal and a transition from metallic‐like to semiconducting‐like transport.

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’.

Thickness‐Programmable Opto‐Memristive Dynamics in 6‐In Wafer‐Scale Atomic‐Layer‐Controlled WS2 for Reservoir Computing

Advanced Functional Materials, EarlyView.
A 6‐in wafer‐scale atomic‐layer‐controlled tungsten disulfide (WS2) is achieved by combining plasma‐assisted synthesis with three‐gas reactive ion etching. Precise layer control enables tunable band‐gap evolution and pulse‐history‐dependent opto‐memristive dynamics.
