Why did Putin invade Ukraine? A theory of degenerate autocracy

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract Many dictatorships end up with a series of disastrous decisions such as Hitler's attack on the Soviet Union or Saddam Hussein's aggression against Kuwait. Even if a certain policy choice is not ultimately fatal for the regime, such as Mao's Big Leap Forward or the Pol Pot's collectivization drive, they typically involve both a miscalculation ...

“I can do math!”: A self‐regulated learning intervention to enhance math‐related motivational factors and performance in middle school

open access: yesBritish Journal of Educational Psychology, EarlyView.
Abstract Introduction Self‐regulated learning (SRL) interventions have been widely recognized for their potential to enhance students' academic achievement; however, their effects on math‐related motivational constructs remain less explored. This study investigated the impact of an SRL intervention on multiple math‐related motivational factors (math ...

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 ...

TrkA abundance is increased in cutaneous nerves in bortezomib‐induced neuropathy

open access: yesBrain Pathology, EarlyView.
Cutaneous nerves in bortezomib‐induced peripheral neuropathy (BIPN) show reduced nerve fiber density, increased TrkA expression, and enhanced dermal angiogenesis, highlighting a pathological switch in NGF/TrkA signaling that may contribute to nerve damage and pain. Abstract Tropomyosin receptor kinase A (TrkA), a high‐affinity receptor for nerve growth

New biosensors and transgenic mice for multiplex cGMP imaging

open access: yesBritish 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
