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 ...

British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract Measurement non‐invariance arises when the psychometric properties of a scale differ across subgroups, undermining the validity of group comparisons. At the item level, this manifests as differential item functioning (DIF), where item responses differ across groups after controlling for the latent trait.

Computing Skinning Weights via Convex Duality
Computer Graphics Forum, EarlyView.We present an alternate optimization method to compute bounded biharmonic skinning weights. Our method relies on a dual formulation, which can be optimized with a nonnegative linear least squares setup. Abstract We study the problem of optimising for skinning weights through the lens of convex duality.

Embedding Optimization of Layouts via Distortion Minimization
Computer Graphics Forum, EarlyView.Abstract Given an embedding of a layout in the surface of a target mesh, we consider the problem of optimizing the embedding geometrically. Layout embeddings partition the surface into multiple disk‐like patches, making them particularly useful for parametrization and remeshing tasks, such as quad‐remeshing, since these problems can then be solved on ...

Cladistics, EarlyView.Abstract Subterranean ecosystems harbour exceptional biodiversity shaped by adaptation to extreme environments, yet remain poorly explored. Cave organisms, restricted to small, isolated populations, are extinction‐prone, making integrative species delimitation essential for biodiversity assessment and conservation.

Cladistics, EarlyView.Abstract In dynamic homology, data must usually be preprocessed to distinguish sequencing artefacts (missing data) from insertion–deletion events, but empirical studies using POY/PhyG have employed manual preprocessing. Here, we compare different procedures for handling missing data for dynamic homology, present Python scripts to automate these ...

Kant on Rational Reference: Theology as transcendental philosophy
European Journal of Philosophy, EarlyView.Abstract The Critical Kant famously held that our cognition requires intuition, or essentially singular representation. Kant is also often understood as taking a dismissive attitude toward his rationalist predecessors' accounts of how we cognize singulars or individuals.

A Non‐Parametric Framework for Correlation Functions on Product Metric Spaces
International Statistical Review, EarlyView.Summary We propose a non‐parametric framework for analysing data defined over products of metric spaces, a versatile class encountered in various fields. This framework accommodates non‐stationarity and seasonality and is applicable to both local and global domains, such as the Earth's surface, as well as domains evolving over linear time or time ...

Linking the Comparison and Graphical Approaches to Bipartite Matching
International Statistical Review, EarlyView.Summary Bipartite record linkage has the goal of identifying observations referring to the same individual, called coreferent observations, across two distinct non‐duplicated datasets. The two main approaches to solve this task are the Fellegi–Sunter model, which relies on pairwise comparisons of observations, and the graphical record linkage model ...
