This is an exhibition catalogue produced by two seminars devoted to the study and restoration of selected pieces from the large collection of plaster casts of ancient sculpture owned by the Phoebe Apperson Hearst Museum of Anthropology and the Department of Classics of the University of California, Berkeley.

Because of lack of space and funding, the casts have languished for decades in storage, often in destructive conditions. The seminars learned and practiced restoration techniques, created displays, informative labels, and this catalogue. In addition to a catalogue of 18 items, this booklet contains brief essays on the history of this collection, the history of plaster cast collections, the use of such casts in American education, plaster casts in antiquity, and the conservation of plaster casts.

The catalogue was edited by Stephen G.Miller and designed by Erin Dintino. The authors of the elements of this catalogue are Jose Abrigo, Mont Allen, Nathan T. Arrington, Raina Chao, Marcia Devoe, Erin Dintino, Megan DuBois, Rebecca Karberg, Stephen G. Miller, Stephanie K. Pearson, J. M. Rygorsky, Boaz Zissu.

Learning Objectives: The objective of this innovation is to provide virtual reality as an alternative method for learners in emergency medicine to build procedural competence. We will also be looking at feasibility of VR for education and participant satisfaction.

As part of a wider virtual reality curriculum, we are developing and assessing the feasibility of using virtual reality as an alternative method for learners to build competence in procedural skills. This innovation is being tested and implemented with medical students rotating through on their 4th year emergency medicine elective. The study’s plan is to look at how practicing procedures with virtual reality compares to more traditional hands-on simulation techniques. Medical students were given a lecture on how to do a surgical chest tube. Then, depending on the month, students were either assigned to practice with virtual reality programs or with simulation task trainers. The following week students were assessed on their ability to walk through and perform a surgical chest tube based on clinical skills evaluation that is already used for emergency medicine residents at VCUhealth. The goal of this innovation is to allow for more easily accessible ways to practice procedures through deliberate practice and allow residents to build experience and competence in procedures in emergency medicine. This has the potential to be especially beneficial in high acuity, low frequency procedures.

We define four versions of equivariant instanton Floer homology (I+, I-, I∞ and I~) for a class of 3-manifolds and SO(3)-bundles over them including all rational homology spheres.

These versions are analogous to the four flavors of monopole and Heegaard Floer homology theories. This construction is functorial for a large class of 4-manifold cobordisms, and agrees with Donaldson’s definition of equivariant instanton homology for integer homology spheres. Furthermore, one of our invariants is isomorphic to Floer’s instanton homology for admissible bundles, and we calculate I∞(Y,E) in all cases it is defined, away from characteristic 2.

The appendix, possibly of independent interest, defines an algebraic construction of three equivariant homology theories for dg-modules over a dg-algebra, the equivariant homology H+(A,M), the coBorel homology H-(A,M), and the Tate homology H∞(A,M).

The constructions of the appendix are used to define our invariants.
