Review of cognitive diagnostic models (CDMs): Recent methodological advancements for addressing practical challenges

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Cognitive diagnostic models (CDMs) have become essential tools for providing fine‐grained information about individuals' mastery of cognitive skills. While prior reviews have emphasized statistical foundations and deep learning‐based developments, this article focuses on recent methodological innovations designed to address persistent ...

Multidimensional unipolar IRT and applications to the measurement of print exposure

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Item response theory (IRT) has been a prominent modelling framework in educational and psychological measurement. Traditional IRT models are bipolar, commonly assuming symmetric measurement link functions and symmetric trait distributions over a latent continuum unbounded at both ends. However, many measured constructs, such as print exposure,

Revisiting reliability and measurement precision: Towards a unified perspective

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract This article revisits the concepts of reliability and measurement precision across classical test theory (CTT), item response theory (IRT) and cognitive diagnosis models (CDMs), emphasizing their conceptual differences and proposing a unified framework.

On the asymmetry, complexity and predicted data patterns of nontraditional item response theory models

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Traditional item response theory (IRT) models involve symmetric response probability functions, but a developing area of research has focused on asymmetric alternatives. To date, these studies have focused primarily on introducing new asymmetric models, detailing their mathematical formulations, explaining how to interpret their item ...

From patient to tumor organoid: Culture protocol choice controls glioblastoma tumor architecture and identity

Brain Pathology, EarlyView.
How glioblastoma organoids are made shapes what they become. Fragment‐based cultures preserve extracellular matrix networks, cellular diversity, and primary tumor identity, whereas dissociation‐based cultures shift toward growth‐adapted states and simplified microenvironments. Abstract Patient‐derived tumor organoids are widely used in cancer research,

L‐VISP: LSTM Visualization for Interpretable Symptom Prediction in Patient Cohorts

Computer Graphics Forum, EarlyView.
L‐VISP is a human‐machine solution that uses visual analytics for LSTM modelling in clinical research. L‐VISP uses custom visual encodings to make multiple LSTM variants interpretable, supporting a full range of analysis, from understanding model operations and evaluating performance to interpreting results in a clinical context.

Infrared Thermographic Assessment of Fatigue Behavior in Bolted Composite Joints

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT This study investigates the temperature evolution of bolted thick glass fiber reinforced polymer composites during fatigue testing. Three different adherend thicknesses (8, 10, and 12 mm) and three different bolt tightening torques (30, 40, and 50 N·$$ \cdotp $$m were considered to evaluate the effects of adherend thickness and bolt tightening

The Development and Validation of the Partial Denture Experience Questionnaire (P‐DEQ): Reliability and Validity

Gerodontology, EarlyView.
ABSTRACT Introduction This paper describes the development and preliminary validation of the Partial Denture Experience Questionnaire (P‐DEQ), a new, condition‐specific instrument designed to measure the multifaceted impacts of living with removable dentures. Methods The P‐DEQ was developed using a multi‐phase, mixed‐methods design. Item generation was
