The literature on social stratification has paid considerable attention to whether and what extent attending prestigious universities is beneficial for graduates’ labor market returns. This paper contributes the by applying a more dynamic perspective in asking graduates from less differ their career progression across fourteen years since entry. It further investigates graduating pays off or di...

When string or M theory is compactified to lower dimensions, the U-duality symmetry predicts so-called exotic branes whose higher-dimensional origin cannot be explained by the standard string or M-theory branes. We argue that exotic branes can be understood in higher dimensions as nongeometric backgrounds or U folds, and that they are important for the physics of systems which originally contai...

In this note we discuss bound states of unor meta-stable brane configurations in various non-trivial (curved) backgrounds. We begin by reviewing some known results concerning brane dynamics on group manifolds. These are then employed to study condensation in cosets of the WZWmodel. While the basic ideas are more general, our presentation focuses on parafermion theories and, closely related, N =...
