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 ...

New biosensors and transgenic mice for multiplex cGMP imaging
British Journal of Pharmacology, EarlyView.Background and Purpose Cyclic guanosine monophosphate (cGMP) is a versatile second messenger that is important for human (patho‐)physiology and pharmacotherapy. Live‐cell imaging of cGMP with biosensors allows to elucidate its spatiotemporal dynamics in real time under close‐to‐native conditions. However, to monitor two separate cGMP pools or cGMP/cAMP

Go Green or Go Digital? A Set‐Theoretic Perspective of Incumbents' Paths to Success
Creativity and Innovation Management, EarlyView.ABSTRACT In response to growing pressures for environmental sustainability and technological advancement, this study examines how firms can effectively integrate green and digital innovations within ambidextrous strategies to enhance performance. Using fuzzy‐set Qualitative Comparative Analysis (fsQCA) on a sample of 175 German manufacturing and ...

An algorithm for analysis of the structure of finitely presented Lie algebras
Discrete Mathematics & Theoretical Computer Science, 1997 We consider the following problem: what is the most general Lie algebra satisfying a given set of Lie polynomial equations? The presentation of Lie algebras by a finite set of generators and defining relations is one of the most general mathematical ...

News shocks, consumer confidence and business cycles
Economica, EarlyView.Abstract We study the causal effects of consumer sentiment shocks on macroeconomic aggregates. By constructing a novel instrument based on major non‐economic news shocks in the USA over 1969–2022, and opinion polls around these events, we identify exogenous changes in consumer confidence.

Economic Inquiry, Volume 63, Issue 2, Page 424-440, April 2025.Abstract Eaton, Kortum, and Kramarz (2011) (EKK) discovered empirical patterns from French manufacturing firms that a baseline firm heterogeneity model could not explain. The authors proposed and estimated a model that closely matches the patterns observed in French data.

Strategic Flip‐Flopping in Political Competition
International Economic Review, EarlyView.ABSTRACT We study candidates' position adjustments in response to information about voters' preferences. Repositioning allows candidates to move closer to the median voter, but it incurs financial and electoral costs. In a subgame‐perfect equilibrium, candidates diverge from the center ex ante if the costs of adjustment are sufficiently large.

Limit Orders and Knightian Uncertainty
International Economic Review, EarlyView.ABSTRACT A wide variety of financial instruments allows risk‐averse traders to reduce their exposure to risk. This raises the question of what financial instruments allow ambiguity‐averse traders to reduce their exposure to ambiguity. We show in this paper that price‐contingent orders, such as limit orders, are sufficient: In a two‐period trading model,
