Timed vs. Untimed Initiation Intervals and the Effects of Confidence on a Golf Putting Task

Description: Low, moderate, and high handicap golfers, while wearing glasses with a blinder on the side, attempted 9 putts differing in length from 5 to 21 ft under timed (less than 3.5s from grounding of club to initiation of back swing) and untimed conditions in a counterbalanced design. Confidence ratings were taken prior to and following each putt. The results revealed a significant condition by handicap group interaction (p=.021). The lower handicap group had a more consistent and lower initiation inte… more

Reverberating Reflections of Whitman: A Dark Romantic Revealed

Description: Walt Whitman has long been celebrated as a Romantic writer who celebrates the self, reveres Nature, claims unity in all things, and sings praises to humanity. However, some of what Whitman has to say has been overlooked. Whitman often questioned the goodness of humanity. He recognized evil in various shapes. He pondered death and the imperturbability of Nature to human death. He exhibited nightmarish imagery in some of his works and gory violence in others. While Whitman has long been called a … more

The Anglo-American Council on Productivity: 1948-1952 British Productivity and the Marshall Plan

Description: The United Kingdom's postwar economic recovery and the usefulness of Marshall Plan aid depended heavily on a rapid increase in exports by the country's manufacturing industries. American aid administrators, however, shocked to discover the British industry's inability to respond to the country's urgent need, insisted on aggressive action to improve productivity. In partial response, a joint venture, called the Anglo-American Council on Productivity (AACP), arranged for sixty-six teams involving… more

Chaucer and the Rhetorical Limits of Exemplary Literature

Description: Though much has been made of Chaucer's saintly characters, relatively little has been made of Chaucer's approach to hagiography. While strictly speaking Chaucer produced only one true saint's life (the Second Nun's Tale), he was repeatedly intrigued and challenged by exemplary literature. The few studies of Chaucer's use of hagiography have tended to claim either his complete orthodoxy as hagiographer, or his outright parody of the genre. My study mediates the orthodoxy/parody split by viewing … more

A Comparison of Points Versus Sounds as Reinforces in Human Operant Research

Description: Research shows that human operant behavior typically differs from non-human operant behavior on schedules of reinforcement. These differences in performance may be related to differences between the experimental preparations used to study human and non-human operant behavior. One such difference is the type of reinforcer used. This experiment analyzed the differential effects of points alone, points backed up by money, and sounds on schedule performance of human subjects. Results show that soun… more

Sexual Identity Development and Heterosexual Mistrust: An Exploratory Study

Description: The sexual identity development process in gay men was the focus of this study. It was theorized that, as a result of negative experiences with the dominant heterosexual culture, gay men might feel mistrustful of heterosexuals in various settings. A new theoretical construct, that of heterosexual mistrust, was identified and explored. A new scale, the Heterosexual Mistrust Inventory (HMI), was created to measure this construct. Gay male subjects' stage of homosexual identity formation (HIF) was… more

Design of a Monitoring System for a Plasma Cleaning Machine

Description: Plasma cleaning is the most effective dry process to remove surface contaminates from a SAW (Surface Acoustical Wave) device. Consistent gas pressures, flows, and good electrical connections between the chamber shelves are necessary for the process to function predictably. In addition, operation of the monitoring system must be transparent to the plasma cleaning unit. This thesis describes a simple solution to the complex problem of monitoring a plasma cleaning system. The monitoring system use… more

Evolution of Vacancy Supersaturations in MeV Si Implanted Silicon

Description: High-energy Si implantation into silicon creates a net defect distribution that is characterized by an excess of interstitials near the projected range and a simultaneous excess of vacancies closer to the surface. This defect distribution is due to the spatial separation between the distributions of interstitials and vacancies created by the forward momentum transferred from the implanted ion to the lattice atom. This dissertation investigates the evolution of the near-surface vacancy excess in… more
