Ability and knowledge: from epistemic transition systems to labelled stit models.

It is possible to know that one can guarantee a certain result and yet not know how to guarantee it. In such cases one has the ability to guarantee something in a causal sense, but not in an epistemic sense. In this paper we focus on two formalisms used to model both conceptions of ability: one formalism based on epistemic transition systems and the other on labelled stit models.

Habit formation of preventive behaviours during the COVID-19 pandemic: a longitudinal study of physical distancing and hand washing.

Background: Since the outbreak of the COVID-19 pandemic, physical distancing and hand washing have been used as effective means to reduce virus transmission in the Netherlands. However, these measures pose a societal challenge as they require people to change their customary behaviours in various contexts. The science of habit formation is potentially useful for informing policy-making in public health, but the current literature largely overlooked the role of habit in predicting and explaining these preventive behaviours.

Conflicting intentions: rectifying the consistency requirements.

Many philosophers are convinced that rationality dictates that one's overall set of intentions be consistent. The starting point and inspiration for our study is Bratman's planning theory of intentions. According to this theory, one needs to appeal to the fulfilment of characteristic planning roles to justify norms that apply to our intentions.

Agents necessitating effects in newtonian time and space: from power and opportunity to effectivity.

We extend logic by adding a spatial dimension. This enables us to distinguish between powers and opportunities of agents. Powers are agent-specific and do not depend on an agent's location.

The DRD2 rs1076560 polymorphism and schizophrenia-related intermediate phenotypes: A systematic review and meta-analysis.

Intermediate phenotypes may contribute to elucidate the genetic determinants of schizophrenia. A regulatory dopamine 2-receptor gene (DRD2) polymorphism (rs1076560; G>T) has been identified as a genetic risk factor for schizophrenia. Studies report conflicting results on its involvement in schizophrenia intermediate phenotypes and no systematic review on this topic has been published.
