Bayesian inference for dynamic Q matrices and attribute trajectories in hidden Markov diagnostic classification models

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Hidden Markov diagnostic classification models capture how students' cognitive attributes evolve over time. This paper introduces a Bayesian Markov chain Monte Carlo algorithm for diagnostic classification models that jointly estimates time‐varying Q matrices, latent attributes, item parameters, attribute class proportions and transition ...

From bias to bliss: Racial preferences and worker productivity in tennis

open access: yesContemporary Economic Policy, EarlyView.
Abstract We investigate the impact of differences in consumers' racial preferences on worker productivity through the example of the home advantage (HA) effect using data on wins in men's tennis from 2001 to 2020 (pre‐COVID‐19). We identify players' racial affiliation as one of five distinct groups by combining clustering and facial recognition methods.

Dynare replication of “A Model of Secular Stagnation: Theory and Quantitative Evaluation” by Eggertsson et al. (2019)

open access: yesEconomic Inquiry, Volume 63, Issue 2, Page 403-423, April 2025.
Abstract This paper replicates the study “A Model of Secular Stagnation: Theory and Quantitative Evaluation” by Eggertsson et al. using the Dynare toolkit. Replication is important as it confirms the results of the original article, provides a user‐friendly version using Dynare, and shows how to deal with large‐scale models with occasionally binding ...

Outbreak of poisoning by sodium hydrogen methylarsonate (MSMA)—an arsenic‐based herbicide—in horses in Brazil

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Arsenic poisoning in horses is rarely reported in the literature. However, arsenic compounds can be present in rodenticides, pesticides, and herbicides, representing a potential source of accidental exposure for horses. Objective To describe the epidemiological, clinical, and laboratory findings from a herd of 31 horses exposed to ...

Lock, relax, load, and shoot: a molecular perspective on Nedd4 regulation

open access: yesThe FEBS Journal, EarlyView.
Structural basis of inactive and active states of the Nedd4 HECT E3 ligase subfamily, following a ‘lock, relax, load, and shoot’ mechanism. In the locked, autoinhibited state, intramolecular domain interactions restrain the HECT domain. Relaxation releases these restraints, allowing loading of ubiquitin onto the catalytic cysteine, followed by the ...

Call Me Maybe: Corporate Bond Prices Upon Missed Call Opportunities

open access: yesFinancial Management, EarlyView.
ABSTRACT In a sample of discretely callable corporate bonds, we find excess returns of approximately 40 bps realized on the release of the issuer's decision to call or not to call. The bonds that could have been profitably called (in‐the‐money bonds) but are not called contribute the most to the bond price jump. We attribute the jump to the revaluation
