Changing Preferences
This is an exploratory document for a new research line in logical semantics which is emerging from several current developments in computer science. Standard logic employs ''at' unstructured sets of statements for its theories and unstructured classes of models for its semantic universes. Nowadays, however, there is an incipient literature on structured universes of models as well as structure...
متن کاملQuerying under Changing Preferences
We present here a formal foundation for an iterative and incremental approach to constructing and evaluating preference queries. Our main focus is query modification: a query transformation approach which works by revising the preference relation in the query. We provide a detailed analysis of the cases where the order-theoretic properties of the preference relation are preserved in the revisio...
متن کاملDeontic Logic and Changing Preferences
This chapter generalizes the dynamic epistemic analysis of information flow to deontic logic and normative reasoning, an area where agents’ evaluation of worlds or outcomes is essential. The relevant dynamics is taken from current logics of preference structure and preference change. These logics are presented in two versions, one with a primitive ‘betterness’ relation between worlds, and one w...
متن کاملCulturing Adult Rat Hippocampal Neurons with Long-Interval Changing Media
Background: Primary cultures of embryonic neurons have been used to introduce a model of neurons in physiological and pathological conditions. However, age-related cellular events limit this method as an optimal model in adult neurodegenerative diseases studies. Besides, short-interval changing media in previous cultures decreases the effectiveness of this model. As an example of this matter, w...
متن کاملEndogenous Majority Rules with Changing Preferences
This paper provides a new explanation why several US states have implemented supermajority requirements for tax increases.We model a dynamic and stochastic OLG economy where individual preferences depend on age and change over time in a systematic way. In this setting, we show that the first population of voters will choose a supermajority rule in order to influence the outcomes of future elect...
