Second harmonic generation (SHG),
a nonlinear optical tool, was used to
characterize DNA bound through a
chemical linker to the flat surface of a
hemispherical lens. Contact angle
measurements were used to guarantee
that the chemical linker did not hydrolyze
under experimental conditions. SHG
experiments followed the effects of salt...
In this paper, Morgan and Orloff survey the contemporary study of states in the social sciences. They begin by tracing the history of scholarship on the state. The authors identify six main clusters of research on states that emerged through the effort to “bring the state back into” history and...
Primary progressive aphasia (PPA) is a debilitating neurodegenerative syndrome that principally impairs the cognitive domain of language. Patients demonstrate deficits in a variety of language faculties including object naming (anomia), word finding, single word and sentence reading, speech comprehension, repetition, syntactic processing, and paraphasia. PPA has been associated with selective...
The work presented in this dissertation is centered on experimental efforts to maximize the sensitivity of surface-enhanced Raman spectroscopy (SERS) and tip-enhanced Raman spectroscopy (TERS) toward their application in ultrasensitive nanoscale chemical analysis. The work focuses on fundamental studies of the plasmonic properties of silver nanostructures, and how those properties...
This dissertation develops a war-centered theory of collectivist regimes. I argue that in a large-scale industrial war of coalition alliances, belligerent nations launch extensive programs of economic mobilization and establish centralized bureaucratic institutions of economic regulation. Because exterior states are likely to restrict interior states in their access to the...
Alzheimer's disease (AD) is a progressive amnestic dementia typified by the pathological self-association of the microtubule-associated tau protein into neurofibrillary tangles (NFTs). Important to NFT formation are numerous modifications of tau, including phosphorylation, truncation, and conformational changes. In addition, AD-associated inflammation promotes the formation of peroxynitrite (ONOO-), a potent nitrating...
The first essay examines how the shift between single-tasking and multitasking influences productivity and workers' bargaining power, and its implications on the distribution of earnings between management and workers. Under single-tasking, a firm can obtain high productivity because workers' hold-up power can provide them with larger incentives to work. In...
This dissertation investigates the nature of apocalyptic fiction in the first Soviet decade. In my introduction, I consider the secondary or underground status that apocalyptic thought assumed during this period vis a vis the prevailing cultural ethos of utopianism. I assert that Russian literary apocalyptic persisted as a genre by...
The first chapter investigates the offshoring decision from a network capacity investment perspective. We analyze a firm that manufactures two products to serve two geographically separated markets using a common component and two localized final assemblies. Two strategic network design questions arise naturally: (1) Should the common part be produced...
Polymers and polyelectrolytes are ideal tools for the development of novel self-assembled materials. The ability to control the length-scales of self-assembly, and thus the properties, for soft materials lies in the understanding and subsequent manipulation of competing intermolecular interactions, such as hydrophobicity, hydrogen bonding, van der Waals, electrostatics. In this...
