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

British 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 ...

Simultaneous detection of gradual and abrupt structural changes in Bayesian longitudinal modelling using entropy and model fit measures

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Although individuals may exhibit both gradual and abrupt changes in their dynamic properties as shaped by both slowly accumulating influences and acute events, existing statistical frameworks offer limited capacity for the simultaneous detection and representation of these distinct change patterns.

Take It Easy! How Flexible Work Arrangements Bust the Commuting Life Satisfaction Nexus

Bulletin of Economic Research, EarlyView.
ABSTRACT Commuting to work can negatively affect people's well‐being. This paper analyzes the effect of commuting distance on subjective well‐being for employees under different work time regimes. The analysis is based on data from the German Socio‐Economic Panel (GSOEP) for 2003–2021.

Measuring Lead Userness: Development and Validation of a Hierarchical Scale

Creativity and Innovation Management, Volume 34, Issue 4, Page 944-962, December 2025.
ABSTRACT Lead user theory has gained traction in both academia and practice, given that involving lead users (LUs) can yield more innovative and commercially successful products. Yet, measurement inconsistencies have hindered consensus on how to reliably assess lead userness.

Risk of acute pancreatitis with DPP‐4 inhibitors versus SGLT2 inhibitors in medication‐naïve individuals with diabetes: A target trial emulation

Diabetes, Obesity and Metabolism, EarlyView.
Abstract Aims We investigated whether dipeptidyl peptidase‐4 inhibitor (DPP‐4i) use was associated with a higher risk of acute pancreatitis compared with sodium–glucose cotransporter 2 inhibitor (SGLT2i) use in antidiabetic medication‐naïve individuals.
