Media are objects with content and character that we describe using in- phrases: in the story, in the picture, in the movie, in the dream... Like the propositional attitudes, these objects present a variety of hard problems for semantic and philosophical analysis. The Semantics of Media is an organized exploration of fundamental questions in the semantics of media.
The first three chapters set out a straightforward model within the possible-worlds framework, and consider how it might account for a range of notions applying to media generally: implicit...

The solar radiant energy is in fact the only source of energy for the basic physical processes taking place in the atmosphere and on the earth's surface. When passing through the atmosphere and being reflected by the ground surface, solar radiation undergoes changes and conversions. Some of it is absorbed in the atmosphere and converted into other forms of energy, mainly into heat, and some is scattered by gases, by dust and by water vapour. Because of absorption and scattering in the atmosphere, solar radiation is changed by the time it reaches the earth's surface. That part of it which...

Stress-induced myocardial ischemia is a frequent manifestation of coronary heart disease, and sympathetic activation is an important precipitating and aggravating factor in such stress- induced ischemia. However, the complex interplay between the sympathetic initiation of myocardial ischemia, ischemia-induced alterations in sympathetic neurotransmission, as well as changes in adrenoceptor density and post-receptor signal transduction that can occur during ischemia remains incompletely understood. Not only the activation of myocardial fJ- adrenoceptors, but also the activation of coronary...
