Bilateral Accidents with Intrinsically Interdependent Costs of Precaution

The standard economic model of bilateral precaution postulates an interdependency between the care taken by injurers and victims that operates through the effects of each on the expected accident loss. This paper considers situations in which each party's precaution affects not only expected accident loss, but also directly affects the other party's cost of taking precaution. Generalizing the economic model of tort law in this way allows for a more complete analysis of when standard tort rules can and cannot induce optimal precaution. When this additional externality is introduced into a model of unilateral harm (where all accident losses are borne by the victim), none of the standard tort liability rules induces socially optimal behavior by both parties. Moreover, under a contributory negligence rule, the only equilibrium is in mixed strategies; this gives rise to the possibility of litigation in equilibrium. A 'tort-like' liability rule that induces socially optimal behavior by both parties is then characterized; this involves a payment by victims to non-negligent injurers whenever an accident occurs. The model is then extended to consider the case of bilateral harm (where both parties suffer accident losses). It is shown that, as long as both parties can sue to recover their accident losses, all negligence-based tort rules lead to socially optimal behavior by both parties.

Hole in the Head: a Play, Accompanied by a Conspectus of Knowledge, Both Repressed and Researched, that Directly Influenced the Playwright in Her Development of a New Work

"Hole in the Head" is a play about a woman who wakes up. Maude wakes up in the first act, and in every subsequent scene she undergoes some form of physical or emotional awakening as characters walk in and out of her front door."Hole in the Head" is accompanied by an introduction that attempts to understand the interplay between creativity and academia through an analysis of theatre, feminist and queer theory, and science.

Investigating the Affects of Cucurbitacin-I on Cellular Motility

Cellular migration is an integral component of many biological processes including immune function, wound healing and cancer cell metastasis. A complete model illustrating the mechanism by which cells accomplish movement is still lacking. Exploring the affects of various drugs on cell motility may be instrumental in discovering new proteins which mediate cell movement. This project aims ultimately to characterize the molecular target of the drug Cucurbitacin-I, a natural plant product. This drug has been shown to inhibit migration of epithelial sheets and may have anti-tumor activity. In this paper, we show that Cucurbitacin-I inhibits the migration of MDCK and B16F1 cells. The drug also affects the integrity of the actin cytoskeleton of these cells by indirectly stabilizing filamentous actin. Cucurbitacin-I does not, however, have an effect on the motility or cytoskeletal morphology of the soil amoeba, Dictyostelium discoidium.
