Evidence suggests both that teacher quality matters for students' outcomes and that principals might not hire the "best" teachers. However, relatively little is known about what characteristics principals value in teachers or how they make hiring decisions. In my dissertation, I use a diverse array of data sources to examine...
Fusion of biological membranes is dictated by the interaction between specialized membrane proteins and the lipid bilayer. Parainfluenza virus 5 (PIV5) mediates fusion using two surface glycoproteins: the fusion protein (F) and the attachment protein hemagglutinin-neuraminidase (HN). Activation of membrane fusion of PIV5 typically occurs at neutral pH, and involves...
The overarching goal of this work is to understand nanometer scale junctions and electron transport through molecules in these junctions. Calculations detailing quantum interference in the electron transport through molecules, and the control of these features, show great potential for use as discrete electronic elements. Concurrent work on the fabrication...
In male mammals, testosterone (T) is critical for sexual differentiation during development and reproductive success in adulthood. This thesis examines the cellular and molecular processes that mediate T's actions in the male brain and reproductive axis. Although T is clearly necessary for sexual behavior, the cellular mechanisms by which it...
Microarrays are powerful tools in gene expression assessment, protein profiling, and protein function screening, as well as cell and tissue analysis. With thousands of small array spots assembled in an ordered array, these small devices makes it possible to screen for multiple targets in a fast, parallel, high-throughput manner. The...
Improving cancer treatments are saving the lives of many young women, however these treatments often lead to premature infertility. The in vitro development of ovarian follicles would provide reproductive options to these women by supporting immature follicle growth following ovarian tissue cryobanking. In addition, the system provides a platform to...
Chapter 1: (Bounds on the Counterfactual Revenue Distributions in Auctions with Reserve Prices) In first-price auctions with interdependent bidder values, the distributions of private signals and values cannot be uniquely recovered from bids in Bayesian Nash equilibria. Non-identification invalidates structural analyses that rely on exact identification of the model primitives....
The genetic information in DNA is transcribed to mRNA and then translated to proteins, which form the building blocks of life. Translation, or protein synthesis, is hence a central cellular process. Decades of experimentation have elucidated a vast wealth of molecular information about discrete translation steps, but the sheer complexity...
Beside the Point: Places in Nabokov's The Gift Peter-John Thomas This dissertation is devoted to the habits of thought embodied in Vladimir Nabokov's last Russian novel, The Gift. Nabokov is famous for creating intricate verbal structures which, however, resist conversion into rigorous propositions. Two major categories of critical response have...
This study in media anthropology uses participant observation, interviews, questionnaires, and recorded broadcasts to analyze how people use FM radio technology in the Koutiala area of southeast Mali, and particularly how they use FM radio to produce locality by relating audience members to one another, to the dominant national culture,...
