The work presented here describes investigations into the optical properties of single silver nanoparticles. The contents of this thesis are divided into two parts: (1) single nanoparticle localized surface plasmon resonance (LSPR) spectroscopy and sensing and (2) approaches to combining LSPR spectroscopy with atomic force and transmission electron microscopies. Part...
Hegel's lectures on aesthetics bear witness not to the cessation of artistic activity as such, but to a progressive decline in its significance for human self-understanding. Still, the nature and extent of this decline remain contested. Is the creation of new art a vestigial activity in a world governed by...
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...
In the first essay, I examine the impact of exogenous changes in stock prices on managers' voluntary disclosures. Specifically, I investigate whether stock price declines prompt managers to voluntarily disclose firm-value-related information that was withheld prior to the decline because it was "unfavorable" but became favorable at a lower stock...
Safe design requires a valid mechanical model and correct probabilistic analysis. Concrete, which is an archetypical quasibrittle material, typically exhibits stable crack propagation in many types of failure. Therefore, a scientific approach requires analyzing concrete failure on the basis of fracture mechanics. One of the simplest ways to incorporate fracture...
This dissertation analyzes the decision process of firms along two dimensions which are central to the field of macroeconomics. First, we study the pricing decision of the firm in a framework where customer base matters. Surveys of managers show that the main reason why firms keep prices stable is that...
This is a detailed study of Congress's China policy, with a view toward building a theory of congressional policymaking. I argue that committees, bicameralism, and presidential veto have severely constrained Congress's ability to legislate on China policy. I analyze China bills introduced between 1973 and 2006. I report evidence that...
Over the past two decades photonic crystals (PhCs) have emerged as a promising new class of materials which offers unprecedented control of light in materials. Recently, atomic layer deposition (ALD) has been shown to be a powerful tool for the infiltration of 3D templates with dielectric or semiconducting materials, which...
Regtech, a reference to the application of new technologies to bank regulation, mandates a conversation about reducing the burden of bank regulation by letting computers take over some of the handling of regulatory text. Bank regulations and the related manuals, guidance, or other supplements are mostly unstructured. Software tools and...
FPGAs are evolving at a rapid pace with improved performance and logic density. However, power efficiency of FPGAs has continuously lagged behind, and hence power optimization of FPGAs is crucial. Trends in technology scaling makes leakage power a serious concern for designers; on the other hand, routing power is the...
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...
The enormous popularity of The Beggar's Opera gave rise to a remarkable series of plays known as ballad opera, a form that dominated the eighteenth-century London stage during the 1730s, a crucial decade in the development of English theatre. Although virtually every major playwright of the period, including Colley Cibber,...
This dissertation analyzes the role of the Dutch city Middelburg around 1600 in stimulating the flower still-life production of Ambrosius Bosschaert. The shift in power from Antwerp to Amsterdam as the center of the northern European art market around 1600 has received much attention without recognition of the important role...
Information has become increasingly important in modern organizations. It is frequently the form and function of work. Queries, novel information, facts and reports are used to complete tasks, coordinate interdependencies, and share knowledge. While information is critical to organizational and individual effectiveness, little is known about the mechanisms whereby information...
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...
This dissertation project explores the relationship between the architectures of black masculinity in America and a specific performance of discreet sexual identity. Through critical ethnographic and discursive exploration, I look closely at a group of black men who describe themselves as being on the "down low" (DL). These men, who...
In high power density transmission systems, Ni-Co secondary hardening steels have shown great potential for next-generation gear applications due to their excellent strength, toughness and superior fatigue performance.
Study of residual stress generation and evolution in Ferrium C61 and C67 gear steels revealed that shot peening and laser peening processes...
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...
Youth with comorbid depression and conduct disorder (CD) in the juvenile justice system are a particularly vulnerable population. Comorbidity of depression and CD, as well as juvenile justice involvement, is associated independently with impairment and negative outcomes. Nevertheless, service provision to this high-need population is especially lacking. The purpose of...
