The utilization of hydrofluoric acid for the preparation of silver vanadium oxide fluorides has been advanced for the synthesis of Ag<sub>4</sub>V<sub>2</sub>O<sub>6</sub>F<sub>2</sub> and Ag<sub>3</sub>VO<sub>2</sub>F<sub>4</sub>. Silver-rich metal oxide fluorides are important battery cathode materials due to the high reduction potential of silver vs. Li, which is made even higher by the incorporation...

Ethicity, race and gender play an important role in labor markets; labor market outcomes such as hiring and compensation are very different across different social groups. These differentials are partly the result of differences in productivity and preferences and partly the result of discrimination. Chapter two uses an audit study...
This project explores historical questions of televisual form and cultural production, centering on the proliferation of media texts that mobilize real-life misfortune as a form of entertainment in U.S. television and culture. Specifically, it examines how a variety of "reality" formats in contemporary television stage and exploit spectacles of failure,...
Since its discovery, RNA interference (RNAi) has become a powerful tool used in laboratories to understand developmental processes, and it is now commonly used to investigate gene function. Using RNAi, scientists can routinely knock out specific genes to prevent their expression, observe its phenotypes, and then help determine the function...
In this dissertation, I examine a near-century old popular theatre genre in Ghana known as the concert party to explore how contemporary political and economic circumstances shape its relationship to the spider-man trickster of Ghanaian (specifically Akan) folklore. Since the early 18th century various writers have attempted to define Ananse's...
Institutions are an important determinant of a society's economic performance. To understand why institutions affect economic activity we have to understand how they affect people's incentives in the economy. The patterns of social interaction and beliefs in a society determine the choice of institution. This dissertation focuses on societies where...
The "Z-width" of a haptic display is the dynamic range of impedances that can be passively rendered. Haptic displays with larger Z-width generally render more realistic feeling virtual environments. The maximum passive impedance a haptic display can render is directly related to the quantity of physical damping in the mechanism,...
Initiation is a performative model that dictates the participation of individuals in the various traditions of Western occultism, locating that individual within a nexus of practices and discourses that facilitate the transmission of occult teachings to that individual. While the act of initiation may be represented by a single performed...
This dissertation reconstructs a critical dialogue between British modernists and their Spanish contemporaries on their shared sense of the urgent tasks, in the wake of World War I, of reimagining the cultural heritage of Europe and cultivating cosmopolitan sensibilities. It assembles and analyzes a network of novels, essays, translations, reviews,...
