British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract Although full‐information maximum likelihood (FIML) estimation is widely used for diagnostic classification models (DCMs), its computational efficiency deteriorates sharply in high‐dimensional settings. This scalability challenge is increasingly critical as DCMs are applied to large‐scale assessments, psychological testing and longitudinal ...

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 ...

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 ...

Evaluating Encodings for Bivariate Edges in Adjacency Matrices
Computer Graphics Forum, EarlyView.Abstract We present the first empirical evaluation of techniques for encoding distributions of quantitative edge values within adjacency matrices. In many real‐world networks, edges represent not a single value but a set of measurements. While adjacency matrices preserve structural clarity, their compact cells limit the simultaneous display of multiple

The plasticisation model of dye diffusion: Part 7
Coloration Technology, EarlyView.Abstract Re‐evaluation using the Williams‐Landel‐Ferry equation, of exhaustion/fixation/adsorption data previously reported for four classes of anionic dye onto three different types of wool substrate, revealed that thermally activated dyeing/desorption behaviour is governed by the thermally regulated structural relaxation times of the respective water‐

Bioethics and the World Order: A Curious Coincidence Between Chinese and African Approaches
Developing World Bioethics, EarlyView.ABSTRACT The post‐1945 world order is standardly pictured as a Westphalian system, in which each state is equal under the law with sovereign authority over its territories. This paper argues that the Westphalian system is changing and examines the implications for bioethics. We show that cross‐border health, economic, ecologic, and sociopolitical risks

Deregulation, government failure, and tragedy: The Report of Phase 2 of the Grenfell Tower Inquiry
Economic Affairs, EarlyView.Abstract The Inquiry into the fire at Grenfell Tower, London, in 2017 has exposed the failures that led to the tragedy in a commendably exhaustive manner. But the explanation of those failures is seriously inadequate. First, they are attributed to deregulation, when the Inquiry itself details the ways in which the cladding of the building was subject ...
