In this paper we present a model of competition between operators on urban local bus routes in which passengers always board the first bus to arrive, and it is costly to revise timetables. The model predictds that timetables are unstable, the operator whose bus was boarded by fewest passengers is the most likely to change its arrival time, and to try to leapfrog its rival by arriving just befor...

Here we deal with the logic of [GuSh 533], which tries to capture polynomial time (for finite models). There it is proved that the logic cannot say much on models with equality only. Here we prove that it cannot say much on models for which we expect it cannot say much, like random enough graphs. This is the result of having a general criterion.

(Itlent studies showed that this factor selectively binds Hgb, and it is now established that virtually the entire Hgh-binding capacity of serum is due to its hp content. Normally the Hp in 100 ml. of serum can bind about 125 mg. Hgb2. The renal handling of Hgb has recently been shown to depend to a large extent upon its binding with Hp. Thus Hgb does not appear in the urine until the Hgb-bindi...

This study examines: (a) the impact of traumatic brain injury (TBI) on emotional empathy, (b) the relationship between emotional empathy and neuropsychological ability, and (c) the influence of low emotional empathy on measures of affect. Eighty-nine patients completed the Balanced Emotional Empathy Scale (BEES), a number of neuropsychological tests, some of which were ecologically valid tests ...

Moral Harassment at Work (MHW) is considered a recurrent practice of humiliation, mockery, isolation, persecution and psychological torture. Its results go beyond the worker private life: represent financial loss, affects the work, the organization, the productivity and the society. This article aims to develop a model of MHW, which characterizes the main components of the phenomenon and their ...

It is often thought that judgments about what we ought to do are limited by judgments about what we can do, or that "ought implies can." We conducted eight experiments to test the link between a range of moral requirements and abilities in ordinary moral evaluations. Moral obligations were repeatedly attributed in tandem with inability, regardless of the type (Experiments 1-3), temporal duratio...

We prove for the logic ∼ CPT ime (the logic from the title) a sufficient condition for two models to be equivalent for any set of sentences which is “small” (certainly any finite set ), parallel to the Ehrenfeucht Fräıssé games. This enables us to show that sentences cannot express some properties in the logic ∼ CPT ime and prove 0-1 laws for it.
