This collection of essays pays tribute to Nancy Freeman Regalado, a ground-breaking scholar in the field of medieval French literature whose research has always pushed beyond disciplinary boundaries. The articles in the volume reflect the depth and diversity of her scholarship, as well as her collaborations with literary critics, philologists, historians, art historians, musicologists, and vocalists - in France, England, and the United States. Inspired by her most recent work, these twenty-four essays are tied together by a single question, rich in ramifications: how does performance shape our understanding of medieval and pre-modern literature and culture, whether the nature of that performance is visual, linguistic, theatrical, musical, religious, didactic, socio-political, or editorial? The studies presented here invite us to look afresh at the interrelationship of audience, author, text, and artifact, to imagine new ways of conceptualizing the creation, transmission, and reception of medieval literature, music, and art.

Motivated by the presence of numerous dark matter clumps in the Milky
Way's halo as expected from the cold dark matter cosmological model,
we conduct numerical simulations to examine the heating of the disk. We
construct an initial galaxy model in equilibrium, with a stable thin disk.
The disk interacts with dark matter clumps for
about 5 Gyr. Three physical effects are examined: first the mass
spectrum of the dark matter clumps, second the initial thickness of
the galactic disk, and third the spatial distribution of
the clumps. We find that the massive end of the mass spectrum
determines the amount of disk heating. Thicker disks suffer less
heating. There is a certain thickness at which the heating owing to the
interaction with the clumps saturates. We also find that the
heating produced by the model which mimics the distribution found in
Standard CDM cosmology is significant and too high to explain the
observational constraints. On the other hand, our model that corresponds to
the clump distribution in a ΛCDM cosmology produces no significant
heating. This result suggests that the ΛCDM cosmology is
preferable with respect to the Standard CDM cosmology in explaining the
thickness of the Milky Way.
