We give a model-independent discussion of fermion masses in four-dimensional het-erotic superstring theories. We discuss the tree level contributions and quantum corrections, including one-loop threshold effects and masses generated as a result of non-perturbative supersymmetry breaking. We also point out that superstring models give rise to a generic µ-term in the effective low energy Lagrangi...

Many historians of sexuality explore how sexual subjectivity has taken shape in recent centuries, while historical sociologists tend to focus upon the intimate and erotic aspects of emergent social institutions. Symbolic interactionist sociology can add a new dimension to the existing debates, shifting the primary focus from the history of sexuality to a theoretically informed analysis of sexua...

Animals approach rewards and cues associated with reward, even when this behavior is irrelevant or detrimental to the attainment of these rewards. Motivated by these findings we study the biology of financially-costly approach behavior in humans. Our subjects passively learned to predict the occurrence of erotic rewards. We show that neuronal responses in ventral striatum during this Pavlovian ...
