Preservation of rare plant species often requires establishment of new populations. Survivorship surveys are the most common method of post-introduction monitoring. However, they provide an incomplete picture of establishment success. This study is an attempt to develop a model for determining establishment success by determining the factors affecting recruitment in...
Brachypodium sylvaticum (Huds.) Beauv. is an invasive grass that can be found in forest
and prairie communities throughout the Willamette Valley, Oregon. It can out-compete
native species of grasses and forbs and become dominant in a broad range of habitats.
This study investigated if there were differences in vegetation structure...
Purposeful introductions of exotic species for rehabilitation efforts following wildfire are common on rangelands in the western U.S., though potential ecological impacts of introduced species in novel environments are often poorly understood. One such introduced species, Kochia prostrata (L.) Schrad (forage kochia) has been seeded on over 200,000 ha throughout...
Industries such as science, technology, engineering and mathematics (STEM), continue to employ fewer women compared to men. These professions that are traditionally considered more masculine sustain gender-imbalanced work forces and are also unattractive to women at an academic level. This thesis explores the hypothesis that performance can be a powerful...
Within The Lamplighter, a novel written in 1854, Maria
Susanna Cummins defines a version of the sentimental novel
that significantly differs from the prescriptive analysis
male critics have offered for the genre. This thesis
argues that feminist theory and recent rhetorical theory
have caused a critical paradigm shift that has...
The phenomenon of phantom limb pain has been well documented for centuries, but little clinical work has been done to alleviate it. Physician and neuroscientist Vilayanur S. Ramachandran began researching this condition nearly two decades ago, and has discovered a promising alternative treatment: mirror-box therapy. This therapy is not yet...
This thesis deals with applications of uniaxial anisotropic crystals for microcavity resonators with partially chaotic underlying ray dynamics. We develop an implementation of the scattering matrix formalism, and relate the eigenvalues and eigenvectors of the scattering matrix to the field distribution of inside the system. Using the developed technique, we...
Novel mucosal vaccines (LL-M2e, LL-HAe, SG-HAe) were constructed from live, non-pathogenic Lactococcus lactis or Streptococcus gordonii that express conserved regions of HA or M2 antigens from avian influenza virus (AIV) A. All three vaccines evoked antigen-specific serum immunoglobulin G (IgG) responses in vaccinated chickens. The addition of the adjuvant cholera...
The two sulfur isotopomers of sulfur trioxide, ³²S¹⁶O₃ and ³⁴S¹⁶O₃, have been studied via high resolution infrared and Coherent anti-Stokes Raman (CARS) spectroscopy. The v₁ symmetric SO stretching Q-branches observed by the latter are quite different, being especially complex for ³²S¹⁶O₃ Understanding this band structure required analysis of infrared-active hot...
This thesis examines the rhetoric of Theodore Dwight Weld's American Slavery
As It Is: Testimony of a Thousand Witnesses. Published anonymously in 1839, Weld's
publication became the longest antislavery tract in American history. It left its mark on
the abolitionist movement itself and future antislavery literary works most notably
Uncle...
