Low-Energy Electron Irradiation of Preheated and Gas-Exposed Single-Wall Carbon Nanotubes

Description: We investigate the conditions under which electron irradiation of single-walled carbon nanotube (SWCNT) bundles with 2 keV electrons produces an increase in the Raman D peak. We find that an increase in the D peak does not occur when SWCNTs are preheated in situ at 600 C for 1 h in ultrahigh vacuum (UHV) before irradiation is performed. Exposing SWCNTs to air or other gases after preheating in UHV and before irradiation results in an increase in the D peak. Small diameter SWCNTs that are not pr… more

Loyalty and Fairness: A Study of the Influence of Moral Foundations on Auditors' Propensity to Subordinate their Judgment

Description: Subordination of judgment is a fundamental threat to auditor objectivity. Subordination of judgment occurs when auditors agree with their superiors either in spite of or without forming their own independent judgments. Many audit procedures rely on independent, critical thinking at every level of the audit team; however, a number of studies suggest that auditors tend to agree with superiors even when a superior's views clearly run contrary to generally accepted accounting principles. While ther… more

Luigi Boccherini's Cello Concerto in B-Flat Major, G.482: Creating a Performance Edition through a Critical Study of the 'Original' Version and Friedrich Grützmacher's Edition

Description: The Cello Concerto in B-flat major, G.482, by Italian composer Luigi Boccherini (1743-1805), is the composer's most beloved work for the instrument, as well as one of the most performed pieces in the Classical concerto repertoire. Historically, cellists performing this work have used an edition prepared by German cellist Friedrich Grützmacher (1832-1903). However, an 'original' version that was discovered in 1949 is significantly different from that of Grützmacher. A comparison of both editions… more

Luigi Rossi: Early Baroque Italian Cantatas for the Modern Singer, with Modern Editions of Selected Works

Description: The early baroque songs, or cantatas, of Luigi Rossi (1597-1653) are largely absent from the canon of standard Italian vocal repertory utilized by young singers and voice teachers today. In this document Rossi’s composition style is considered, along with modern edition trends, within the emerging genre of Italian early baroque song. Several of Luigi Rossi’s vocal works — chosen for their simplicity, brevity, dramatic content, and suitability for a young singer — are presented in modern transcr… more

"Man Up!": Exploring Intersections of Sport Participation, Masculinity, Psychological Distress and Help-Seeking Attitudes

Description: Contemporary masculinity research has focused on the ways in which socialized masculine ideologies influence, especially negatively, the lives of men. Adherence to traditional masculine norms has been inversely associated with psychological help-seeking yet positively related to psychological distress and substance use. Though sport has been conceptualized as an environment in which masculine ideologies (e.g., emphasis on competition) are learned and reinforced, few studies have quantitatively … more

Manipulating Sucrose Proton Symporters to Understand Phloem Loading

Description: Phloem vascular tissues transport sugars synthesized by photosynthesis in mature leaves by a process called phloem loading in source tissues and unloading in sink tissues. Phloem loading in source leaves is catalyzed by Suc/H+ symporters (SUTs) which are energized by proton motive force. In Arabidopsis the principal and perhaps exclusive SUT catalyzing phloem loading is AtSUC2. In mutant plants harboring a T-DNA insertion in each of the functional SUT-family members, only Atsuc2 mutants demonst… more

Manipulations of Sucrose/Proton Symporters and Proton-pumping Pyrophosphatase Lead to Enhanced Phloem Transport But Have Contrasting Effects on Plant Biomass

Description: Delivery of photoassimilate, mainly sucrose (Suc) from photoautotrophic source leaves provides the substrate for the growth and maintenance of sink tissues such as roots, storage tissues, flowers and fruits, juvenile organs, and seeds. Phloem loading is the energized process of accumulating solute in the sieve element/companion cell complex of source leaf phloem to generate the hydrostatic pressure that drives long-distance transport. In many plants this is catalyzed by Suc/Proton (H+) symporte… more

Market Efficiency, Arbitrage and the NYMEX Crude Oil Futures Market

Description: Since Engle and Granger formulated the concept of cointegration in 1987, the literature has extensively examined the unbiasedness of the commodity futures prices using the cointegration-based technique. Despite intense attention, many of the previous studies suffer from the contradicting empirical results. That is, the cointegration test and the stationarity test on the differential contradict each other. In marked contrast, my dissertation develops the no-arbitrage cost-of-carry model in the N… more
