In this thesis, I examine the ways in which the television series Twin Peaks represents
the feminine through a textual analysis of the character Audrey Home. Using reader-response
theory, I seek to show that while the series conforms to patriarchal media
conventions such as the male gaze and narrative stereotypes...
Forest species classifications are becoming increasingly automated as advances are made in machine learning. The algorithms used to identify tree species range from simple decision trees to intricate neural networks, and often excel in accurately delineating tree species. However, complex algorithms can have high input costs, including the cost of...
Public lands in the Pacific Northwest are managed for multiple uses including timber production, recreation and aesthetic value, maintaining wildlife habitat, conserving native species, and carbon storage. Wildfires impact large areas encompassing broad environmental conditions. Interactions among underlying environmental gradients and alteration of overstory competition by fire of varying severities...
On April 20th, 2010 the Deepwater Horizon drilling rig in the Gulf of Mexico malfunctioned leading to a 4.9 million barrel oil spill. The released oil affected marine life, coastal ecosystems, and the economic framework of the Gulf of Mexico. The Gulf spill spurred research on absorbent materials and engineering...
In the past decade, declines in amphibian populations have captured scientific and popular interest. The causes of the declines are likely to be complex and involve interactions between several environmental stressors. Using multifactorial experiments, I investigated the combined effects of several anthropogenic stressors on developing amphibians in Oregon, USA. In...

Abstract: We prove that for all ergodic extensions S-1 of a transformation by a locally compact second countable group G, and for all G-extensions S₂ of an aperiodic transformation, there is a relative speedup of S₁ that is relatively isomorphic to S₂. We apply this result to give necessary and...
Development of protocols and media for culturing immune cells from marine invertebrates has not kept pace with advancements in mammalian immune cell culture, the latter having been driven by the need to understand the causes of and develop therapies for human and animal diseases.

Low lung function is a feature of several pulmonary disorders, such as uncontrolled asthma and chronic obstructive pulmonary disease (COPD). The objective of this study is to investigate...
Healthcare access exhibits differing levels of complexity, often requiring multi-disciplinary approaches to study its barriers and enablers. Though Argentina has achieved nominal universal healthcare coverage through its public healthcare system, full effective coverage has not been achieved. The public system also has a parallel private care system, adding further complexity...
Coastally trapped wind reversals along the U.S. west coast, which are often accompanied by a northward surge of fog or stratus, are an important warm—season forecast problem due to their impact on coastal maritime activities and airport operations. Previous studies identified several possible dynamic mechanisms that could be responsible for...

Feminist compositionists have long argued for addressing the feminization of composition, or its association with low value “women’s work,” by revaluing caring labor (Enos; Heinert and Phillips; Tuell). However, this argument assumes that writing teachers’ care work is beneficial for all students and teachers. Focusing on responding to student writing...
In recent years, studies dealing with temperature regulation,
temperature sensitivity, and physiological responses to temperature

notable that snakes have been largely ignored in such studies. This
no doubt is due to their less direct relationship to ancestral endotherms.
However, problems...
