Humans attend to social cues in order to understand and predict others’ behavior. Facial expressions and gaze direction provide valuable information to infer others’mental states and intentions. The present study examined the mechanism of gaze following in the context of participants’ expectations about successive action steps of an observed actor. We embedded a gaze-cueing manipulation within ...

We consider the future dynamics of a transient phantom dominated phase of the universe in LQC and in the RS braneworld, which both have a non-standard Friedmann equation. We find that for a certain class of potentials, the Hubble parameter oscillates with simple harmonic motion in the LQC case and therefore avoids any future singularity. For more general potentials we find that damping effects ...

One reason why firms exist, this paper argues, is because they are suitable organizations within which cooperative production systems based on human social predispositions can evolve. In addition, we show how an entrepreneur, given these predispositions, can shape human behavior within a firm. To illustrate these processes, we will present a model that depicts how the biased transmission of cul...

An enhanced binding of an N -particle system interacting through a scalar bose field is investigated, where N ≥ 2. It is not assumed that this system has a ground state for a zero coupling. It is shown, however, that there exists a ground state for a sufficiently large values of coupling constants. When the coupling constant is sufficiently large, N particles are bound to each other by the scal...

The HVZ theorem is proven for the pseudorelativistic N electron Jansen-Hess operator (2 ≤ N ≤ Z) which acts on the spinor Hilbert space A(H1(R)⊗C) where A denotes antisymmetrization with respect to particle exchange. This ’no pair’ operator results from the decoupling of the electron and positron degrees of freedom up to second order in the central potential strength γ = Ze. 2000 Mathematics Su...

Postcopulatory competition between males, in the form of sperm competition, is a widespread phenomenon in many animal species. The extent to which sperm competition has been an important selective pressure during human evolution remains controversial, however. The authors review critically the evidence that human males and females have psychological, behavioral, and physiological adaptations th...
