An extension of the basic local independence model to multiple observed classifications

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract The basic local independence model (BLIM) is appropriate in situations where populations do not differ in the probabilities of the knowledge states and the probabilities of careless errors and lucky guesses of the items. In some situations, this is not the case. This work introduces the multiple observed classification local independence model

Reliability measures in knowledge structure theory

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract In knowledge structure theory (KST) framework, this study evaluates the reliability of knowledge state estimation by introducing two key measures: the expected accuracy rate and the expected discrepancy. The accuracy rate quantifies the likelihood that the estimated knowledge state aligns with the true state, while the expected discrepancy ...

Identifiability conditions in cognitive diagnosis: Implications for Q‐matrix estimation algorithms

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract The Q‐matrix of a cognitively diagnostic assessment (CDA), documenting the item‐attribute associations, is a key component of any CDA. However, the true Q‐matrix underlying a CDA is never known and must be estimated—typically by content experts.

Composite marginal likelihood estimation of higher‐order diagnostic classification models under high dimensionality

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 ...

$\Lambda$CDM $\cup$ MOND

, 2022
It has been demonstrated that the difference between the Renormalised Brane World (RBW) model and the Lambda Cold Dark Matter ($\Lambda$CDM) model occurs only at sufficiently distant times. In this paper, it is shown that for spherically symmetric situations an analog deviation between the RBW model and Newton's theory occurs at large distances.

Impact of Oral Sebetralstat on Anxiety Associated With Hereditary Angioedema Attacks

Clinical &Experimental Allergy, EarlyView.
In the phase 3 KONFIDENT trial of oral sebetralstat for on‐demand treatment of hereditary angioedema attacks, many attacks induced moderate‐to‐extreme anxiety. Sebetralstat reduced anxiety versus placebo; time to reductions agreed with trial endpoints, such as time to beginning of symptom relief.

Green Developmentalism? The Political Economy of Hydropower in India in the 21st Century

Development and Change, EarlyView.
ABSTRACT This article critically examines the political economy of hydropower in India since its global reconfiguration as ‘green energy’ in the early 2000s. While an opportune convergence of interests among key global, national and subnational stakeholders contributed to the greening of hydropower in India, this reframing did not produce the expected ...

Competitive interactions modify the direct effects of climate

Ecography, EarlyView.
As the climate is changing, species respond by changing their distributions and abundances. The effects of climate are not only direct, but also occur via changes in biotic interactions, such as competition. Yet, the role of competition in mediating the effects of climate is still largely unclear.
