In his seminal work, “Demonstratives”, David Kaplan shows how to define validity (or logical truth) for a language containing indexical expressions such as ‘I’, ‘now’, ‘today’, ‘that’, and others. Kaplan’s great insight in that work is that the indices for context and for circumstances of evaluation (which Kaplan takes to be time and world) play conceptually distinct roles in semantics. To capt...

This paper is an exposition of the so-called injective Morita contexts (in which the connecting bimodule morphisms are injective) and Morita α-contexts (in which the connecting bimodules enjoy some local projectivity in the sense of ZimmermannHuisgen). Motivated by situations in which only one trace ideal is in action, or the compatibility between the bimodule morphisms is not needed, we introd...

We describe a system that combines default reasoning with contexts. Contexts are arranged in a hierarchy where more specific contexts represent revisions of the state of belief in more general contexts. We describe our algorithm for default reasoning in a context hierarchy and provide a translation of our representation into a default logic theory whose inferences agree with our algorithm. We c...

The survival of an organization depends partly on its ongoing ability to integrate new members into the fold while simultaneously allowing if not encouraging organizational change. Organizational socialization is the process by which individuals become part of an organization’s pattern of activities (Anderson, Riddle & Martin, 1999). This broad definition accommodates the impact of both the org...
