Revonsuo's influential Threat Simulation Theory (TST) predicts that people exposed to survival threats will have more threat dreams, and evince enhanced responses to dream threats, compared to those living in relatively safe conditions. Participants in a high crime area (South Africa: n=208) differed significantly from participants in a low crime area (Wales, UK: n=116) in having greater recent...

Abstract Introduction Psychological resilience can be viewed as a personality trait, an ability to bounce back, or positive outcome after life adversities. Although there have been increasing reports of the importance sleep and circadian factors in contributing individual’s resilience, current studies were devoid objective measurements in-depth analysis. Whether psychological is related slow wa...

The paper presents an overview of a formalism, called Point Interval Logic, and its application for temporal and spatial knowledge representation and reasoning. A graph based approach, called Point Graph, is shown to implement the inference mechanism of the logic for both temporal and spatial statements. The formalism handles both qualitative and quantitative aspects of the information. A discu...

A methodology for modeling temporal (timesensitive) aspects of discrete-event systems is presented. A formalism of temporal logic which incorporates both point and interval descriptions of time is formulated, which is an extension of Allen’s interval logic [1]. A formal axiomatic system of this point-interval logic is presented. A graph model is shown to implement the axiomatic system of point-...
