Inquisitive modal logic, InqML, is a generalisation of standard Kripke-style modal logic. In its epistemic incarnation, it extends standard epistemic logic to capture not just the information that agents have, but also the questions that they are interested in. Technically, InqML fits within the family of logics based on team semantics. From a model-theoretic perspective, it takes us a step in the direction of monadic second-order logic, as inquisitive modal operators involve quantification over sets of worlds. We introduce and investigate (...) the natural notion of bisimulation equivalence in the setting of InqML. We compare the expressiveness of InqML and first-order logic in the context of relational structures with two sorts, one for worlds and one for information states, and characterise inquisitive modal logic as the bisimulation invariant fragment of first-order logic over various natural classes of two-sorted structures.

Cunha and Caldieraro (2009) investigated whether sunk-cost effects, which are well documented in hypothetical situations involving monetary investments, also occur in choice situations with purely behavioral investments. Their results suggest that decision makers indeed fall prey to behavioral sunk-cost effects under certain circumstances. I have been unable to replicate their pattern of results in three separate investigations. In these studies, I attempted to recover the effect using two other behavioral effort manipulations in addition to the manipulation used by Cunha and (...) Caldieraro. This failure to replicate the pattern of results calls into question the robustness of the initial findings. (shrink)

Hay toda una serie de preguntas que giran en torno a la problemática interna misma de la Scienza Nuova, y que sólo un "nuevo" concepto de ciencia -vinculado a la crítica de Vico a la formación de sistemas característica de la temprana Modernidad- las consigue responder de manera efectiva, bosquejando una nueva idea "orgánica" entre saber especulativo-teórico y saber orientado a los estados de cosas.There is a whole series of questions that revolves around the core problem of the Scienza Nuova: (...) only a "new" concept of science -linked to Vico's criticism of the formation of systems, characteristic of the early modernity- is able to respond to these questions in an effective manner, sketching a new "organic" idea between speculative-theoretical knowledge and knowledge directed to the state of things.
