This paper defends a reading of Hennan Melville's Moby-Dick that elevates Ishmael's status from mere narrator of Ahab's tragedy to that of protagonist of his own story, a novel of epistemological seafaring. As a metaphysical quester, Ishmael provides the novel's only reliable and complex vision of the condition of man...
Reactor refueling is a computationally intensive
problem solving process that requires automation since
significant resources are expended upon the search for
an optimal core loading. Without imposing some

A majority of eighteenth-century novels remain in regular print over two hundred years since their inception. Yet with the possible exception of Robinson Crusoe, they have largely fallen out of popularity, rarely appearing on "The Summer's Hottest Reading" lists or receiving celebrity endorsement. I consider Ian Watt's foundational study, The...
I studied developmental rates in a suite of temperate and tropical passerine bird species from the New World to test the hypothesis that tropical passerines exhibit slower patterns of growth and development than temperate birds. I also investigated how the expression of several developmental rates varied with life history traits...
I assessed potential barriers to dispersal using homing tendency and investigated the movements and settlement site selection of pygmy rabbits (Brachylagus idahoensis) after short distance translocations in southeastern Oregon from June – December 2008. I captured, radio marked, and translocated 59 pygmy rabbits 1-2 km across landscapes with (1) continuous...

This investigation examines the demographic make-up of the Supreme Court Bar in the Roberts Court and compares it to previous iterations of the Supreme Court Bar, as well as the national...
Ralph Ellison died without ever completing his second novel. After his death, the executor of his literary estate, John F. Callahan, edited Ellison's work into a novel published under the title Juneteenth. This thesis examines the problems posed by Ellison's posthumously released text, especially the issues of authorial intent and...
In this thesis, I examine some of the relationships between hierarchy and community that exist in institutions. Within institutions, individuals are separated from one another and organized hierarchically based on arbitrary inequalities. In general, I discusses inequalities based on race, class, gender, sexual orientation, age, ability, etc. Institutions organized based...
Developing accurate predictive distribution models requires adequately representing relevant spatial and temporal scales, as these scales are ultimately reflective of the relationships between distributions and influential environmental conditions. In this research, we considered both spatial and temporal scale and the influence each has on predicting broad-scale distributions of two disparate...

During the 1400s – 1600s, spalted wood was an expensive commodity used in marquetry style artworks across primarily Germany and Italy. It fell out of favor during the Industrial Revolution, but is currently experiencing resurgence in popularity with US woodturners. How spalted wood is used, and what types of spalted...
This paper explores the language theories of Gary Snyder, an important modern environmental author whose early work was associated with the Beat movement of the early 1950's. I am particularly interested in Snyder's thoughts on how language relates to nature. I focus primarily on Snyder's prose in attempts to understand...
Curricular models and teaching techniques that support college students as the primary authors of their writing-across-the-curriculum experiences remain largely unexplored. This thesis addresses that research gap by investigating the use of a start-of-term writing self-assessment and goal-setting questionnaire (STQ) for upper-division undergraduates taking writing-intensive (WI) college courses in their majors....
Spalting fungi show strong potential as natural colorants on a variety of materials, specifically textiles and wood. Four species of spalting fungi are currently utilized in this manner: Scytalidium cuboideum, which produces a red pigment called draconin red, Scytalidium ganodermophthorum, that produces an unknown yellow pigment, and Chlorociboria aeruginosa and...
Recent changes in the historiography of American Transcendentalism

Models of a species’ distribution and models of a species’ spatially explicit density are valuable tools for conservation. They allow researchers to estimate changes in distributions, densities, and populations, based on changing environmental conditions. To trust such estimates, however, the quality of models is exceedingly important. Model performance can be...
High severity fire is a historical and integral disturbance process in coniferous
forest types. Compounded disturbances such as multiple fires or post-disturbance

Nathaniel Hawthorne lived and wrote in an age of reform efforts, and the progressive movement with which he was most familiar was Transcendentalism. However, he was not sympathetic with Emerson's idealism, a sentiment which comes out in his fiction in way of critique. Throughout Hawthorne's work there is an emphasis...
Commercial methodologies for producing fungal pigments are of worldwide interest due to the desire to move away from synthetic dyes. Chlorociboria species and Scytalidium species have been reported to produce sufficient yields of pigments for commercial production and have attracted special attention because of their use in spalted wood applications....
This thesis is a study of Herman Melville’s symbolism. I have chosen to investigate the elemental images of water, fire, and stone in Moby-Dick (1851), Pierre; Or, The Ambiguities (1852), and Clarel; A Poem and Pilgrimage in the Holy Land (1876). This work is a semiotic study, insofar as the...
Bildungsroman in Contemporary Black Women's Fiction is a study of Toni
Morrison's The Bluest Eye and Alice Walker's The Color Purple. Both of these writers

Patterns of nest attendance behavior by breeding birds represent a parent-offspring trade-off in which adults balance self-maintenance with parental care decisions.
Incubation, in particular, is of interest because adults must provide an environment
suitable for embryonic development through nest-building and contact-incubation.
We evaluated how adult incubation constancy and nest visitation...
The effect of gadolinia particles on the assembly criticality
of a light water reactor was investigated using two 2-group
