Rational Foundationalism
Everything that exists has an explanation of its existence. Philosophers have used this principle in arguments for the existence of something ontologically fundamental, an ultimate ground of being, such as God. But if everything has an explanation of its existence, so, too, does whatever is …

Rational spamming
… that consumers with limited attention may rationally choose to unfollow a firm. This happens if consumers already know enough about the firm's quality and if the firm advertises too intensely. However, firms might still find intensive advertising the optimal strategy - if a firm is …

Rational Multiparty Computation
<p>The field of <em>rational cryptography</em> considers the design of cryptographic protocols in the presence of rational agents seeking to maximize local utility functions. This departs from the standard secure multiparty computation setting, where players are assumed to be either honest or …

Rational secret sharing
… Sharing in the Cryptographic model, designing a Rational Secret Sharing protocol which works in the Game Theoretic model has proved challenging. In this thesis, we contrast several recently proposed protocols for Rational Secret Sharing based on their channel models, utility tolerances, …

Momentum: A Rational Interpretation
In this thesis, I examine existing theories that attempt to explain the asset pricing phenomenon known as momentum. I revisit the seminal work of Chordia and Shivakumar (2002); Cooper, Guiterrez and Hameed (2004); and Stivers and Sun (2010). Using an updated sample, I reexamine their findings, …

Is nuclear deterrence rational?
… In Chapter One I discuss cases involving rational opponents who possess large-scale nuclear capability. The discussion focuses on a refutation and counter argument to David Gauthier's view of this sort of case. I claim that we must adopt a model of decision making according to which …

Rational Effect Size Measurement
… convey the information relevant for rationally choosing the best intervention? The arguments I present in this thesis suggest otherwise: Effect sizes do not always convey the information that matters to rationally choose between interventions, and effect size measures differ in when …

Super-efficient rational proofs
… expert maximizes her utility by being honest. A rational proof is an interactive proof where the prover, Merlin, is neither honest nor malicious, but rational. That is, Merlin acts in order to maximize his own utility. I previously introduced and studied Rational Proofs when the verifier, Arthur, …

Deformation invariance of rational pairs
Rational pairs, recently introduced by Kollár and Kovács, generalize rational singularities to pairs (X,D). Here X is a normal variety and D is a reduced divisor on X. Integral to the definition of a rational pair is the notion of a thrifty resolution, also defined by Kollár and Kovács, and in …

Rational design of synthetic metalloproteins
This dissertation work focuses on the design of metal-binding a-helical coiled coils. They provide a simple yet unique model to study both metal-protein and protein-protein interactions and serve as means to gain knowledge that is required for preparation of synthetic materials with …

The Rational Significance of Desire
… reasons. This is because a desire has no more rational significance than a guess or coin-flip. My argument relies on what I call the non-substitutability principle, the thesis that (all things being equal) one cannot substitute something that lacks rational significance, relative to some …

Rational Points on Lattice Varieties
… In this thesis we investigate the properties of rational points on lattice varieties over Witt vectors with algebraically closed residue field in prime characteristic. These varieties are defined over a finite field. For varieties over finite field, the local zeta function encapsulates valuable …

On planar rational cuspidal curves
This thesis studies rational curves in the complex projective plane that are homeomorphic to their normalizations. We derive some combinatorial constraints on such curves from a result of Borodzik-Livingston in Heegaard-Floer homology. Using these constraints and other tools from algebraic …

On Projective Planes & Rational Identities
… corresponds precisely to the theory of integral rational identities, restricted to division rings D. The first chapter of this paper introduces projective planes, develops the concept of an intersection theorem, and expounds upon the Theorem of Desargues; the discussion culminates with a proof of …

The rational design of dermatological formulations
In order to understand the role of the formulation components in topical drug delivery it is necessary to separate the various contributing factors, these include thermodynamic activity effects, changes in the ionisation state of the permeant and alteration of the membrane properties. Three model …

Rational Schur Rings over Abelian Groups
<p>In 1993, Muzychuk showed that the rational S-rings over a cyclic group Z_n are in one-to-one correspondence with sublattices of the divisor lattice of n, or equivalently, with sublattices of the lattice of subgroups of Z_n. This idea is easily extended to show that for any finite group G, …
