In this thesis, we investigated a sequential decision making problem. We tested
different policies for online portfolio optimization: for a given number of assets and
a time horizon, the weights on assets are rebalanced at every time step according to

The purpose of this thesis was to simultaneously test a new theoretical model,
vicarious hypocrisy, which has been shown to produce changes in people’s
sunblock usage attitudes and behavior, and to apply this model to another
important health domain, dental…

This research explores the metabolic role of the gut microbiota in the global
obesity crisis and rising threat of global warming. Enteric microbiota in the rumen emit
methane as a by-product of metabolite degradation. Experiments – primarily on mice –

Detecting and characterizing extrasolar planets has become a very relevant field in Astrophysics. There are several methods to achieve this, but by far the most difficult and potentially most rewarding approach is direct imaging of the planets. Coronagraphs can be…

Although we represent other people in terms of both what they look like and how they behave, these two aspects of person knowledge have rarely been studied together. While vision scientists have focused on the processing of faces and bodies,…

My dissertation centers on the meaning of dreams as interpreted by literati in the late Ming (1368-1644), viewed through the lens of the 1636 encyclopedia Forest of Dreams. This thirty-four-juan tome is the largest extant Chinese dream encyclopedia and includes…

We describe an adaptation of the knowledge gradient, originally developed for discrete ranking and selection problems, to the problem of calibrating continuous parameters for the purpose of tuning a simulator. The knowledge gradient for continuous parameters uses a continuous approximation…

Amidst the disintegration of the Qing Empire (1644-1911), men and women in China began to understand their differences in terms of modern scientific knowledge. Why Sex Mattered provides an explanation for the relatively recent emergence of a psycho-biological notion of…

Current theories of physics cognition require specification of complex mechanisms for explaining knowledge acquisition. I demonstrate that a quantitative model of physics perception can be constructed by assuming that physics problem perception provides an optimal summary of a set of…

This dissertation is the first comprehensive and interdisciplinary study of Ottoman economic thought within the context of modernization during the reign of Abdülhamid II (1876-1909). Drawing on a broad array of primary sources ranging from textbooks and manuals of economics…
