Many protected areas or parks in developing countries have buffer zones at their
boundaries to achieve the dual goals of protecting park resources and providing
resource benefits to neighbouring people. Despite the prevalence of these zoning
policies, few behavioural models of people’s buffer zone use inform the sizing and
management...
Tropical fruit aromas are prominent in wines like Sauvignon Blanc, one of the most abundant white wines in the United States. With high consumer interest for these aromas, it has become increasingly important to understand the factors that influence the desired tropical fruit aromas in white wines. Understanding the causes...
Monoterpenes are important volatile compounds to the aroma of many white wines. Many monoterpenes are chiral and found in wine as different isomers. These isomers (also known as enantiomers) are non-superimposable mirror images of each other, maintain the same molecular structure and in many instances possess different sensory characteristics. Much...

The existing imaging components have undergone little modification since the experiment's inception...
This thesis explores the artistic imperatives and internal struggles of women painters in two novels, Kate Chopin's The Awakening (1899) and Virginia Woolf's To the Lighthouse (1927). I identify Chopin's Edna Pontellier and Woolf’s Lily Briscoe as painters who exhibit Impressionist strains, both in how they paint and how they...
In this project, I explore the use of monomania as a literary and rhetorical device that pathologizes deviance from certain norms—in this case, sexual and political norms— and allows for contradiction, dissonance, and reform. Using Nathaniel Hawthorne’s short story “The Birthmark” and Edmund Clarence Stedman’s poem “How Old Brown Took...
Physics sensemaking is a growing topic of study within the physics education community. Many lenses have been used to study sensemaking but few have considered how time and instruction can impact student sensemaking practices and ideas. In this dissertation, I present four studies that address four major questions: What sensemaking...
Bayesian Optimization (BO) methods are often used to optimize an unknown function f(•) that is costly to evaluate. They typically work in an iterative manner. In each iteration, given a set of observation points, BO algorithms select k ≥ 1 points to be evaluated. The results of those points are...
A comprehensive tribal-level classification for the world's subfamilies of Hesperiidae, the skipper butterflies, is proposed for the first time. Phylogenetic relationships between tribes and subfamilies are inferred using DNA sequence data from three gene regions: 943 bp of cytochrome oxidase subunit I (COI) (in the mitochondrial genome), 739 bp of...
This study lays the groundwork on potential techniques that could be employed to improve the post-thaw wash processing of cryopreserved human red blood cells. Transfusion of red blood cells is one of the most commonly practiced procedures in clinical medicine. Millions of red blood cell units are transfused to patients...
Physicists solve problems and communicate their work using many external representations, such as equations, words, diagrams, graphs, sketches, pictures, and more. To learn physics, then, students must learn to use external representations. In this dissertation, I present three manuscripts. Each manuscript discusses how upper-division Paradigms in Physics students use multiple...
On a global scale, illicit economies have dramatic impacts on the physical environment. Cocaine trafficking has been recognized as a major driver of deforestation inside Central American protected areas. A key problem in studying and managing the environmental impacts of illicit economic activity is the difficulty in obtaining reliable data....
Like other species interactions in ecological systems, host-pathogen interactions are influenced by environmental factors, landscape characteristics and the broader community context. My thesis explores the potential influences of food-web interactions (Chapter 2), climate change (Chapter 3), landscape structure and host movement patterns (Chapter 4), and the combined influences of local...
There is substantial interest in the application of mindfulness in counseling and psychotherapy. The appeal of mindfulness training and mindfulness-based interventions has increased as research continues to demonstrate benefits. Mindfulness practice has not only been effective in clinical applications with clients, but has also been conceptualized as beneficial for counselors...

Before we can write intelligently concerning
any subject, we must understand exactly what we are
writing about. As the title tells us, this thesis
deals exclusively with the work and incidentally with
the lives of Robert and Elizabeth Barrett Browning, two
notable nineteenth century poets.
A number of thinkers are becoming increasingly persuaded
that our anthropocentric view of nature is inadequate, that we
need a "new morality" with regard to the environment. In this
essay, I argue that an alternative to anthropocentricism is
available to us now-and has been since at least 1836. I look...
Gadolinium is an important element to the Nuclear Fuel Industry. Two
of the seven naturally occurring isotopes of gadolinium have very large

¹⁵⁵
Gd
and
¹⁵⁷ Gd readily absorb thermal neutrons and transmute to
¹⁵⁶
Gd and
¹⁵⁸
Gd which are...
This thesis situates a discussion of Thoreau's later natural history essays in the context of the author's other writings. Beginning with an examination of the writings of Thoreau's friend and mentor Ralph Waldo Emerson, this paper examines Thoreau's relation to and departure from Emerson's understanding of time, place, and pattern...
Transects were run at five locations in the Benton County area searching for
samples of Chlorociboria spp. on dead wood, with fifteen total samples found. Of
these samples, eight samples had the wood species identified, with the majority found

The prevalence of obesity is increasing worldwide, causing a subsequent increase in insulin resistance (IR), metabolic disorders, and cardiovascular diseases. Although these conditions significantly impact both the individual and society, their etiologies have not been discovered, inhibiting potential prevention and treatment. Alterations to mitochondrial metabolism are implicated in the development...
Scytalidium ganodermophthorum (Xylogone ganodermophthora) is known as a yellow-pigmenting spalting fungus. However, recent observations have indicated that the dichloromethane-extracted pigment produced by S. ganodermophthorum can vary in color from yellow to green to red to purple, depending on the age of the fungus at harvesting. The timeline and mechanisms behind...
When a person is tasting wine, they first evaluate the appearance and then the aroma. The smell of wine is a crucial part of tasting and the aromas emanating from the wine should be pleasant. Aroma quality perceived in wine is determined by multiple interactions of the components found in...
Physicists seek to understand the world and often use mathematics to aid in attaining that goal. Thus when doing mathematics they often interrogate their results in order to ensure that they align with their expectations and to gain new insight into how the world works. This seeking of coherence between...
The purpose of this research was to investigate the
effectiveness of using an early childhood language intervention
program with children who had been determined to be

Quantum mechanics is increasingly being taught with a spins-first approach where instructors use simple spin systems to introduce the principles of quantum mechanics rather than systems with wavefunctions. One of the defining characteristics of a spins-first approach is that systems studied have discrete bases, whereas systems with wavefunctions have continuous...
Wine taste and mouthfeel are essential factors that determine consumer acceptance, consumer preference, and wine quality. The three taste descriptors, sweet, sour, and bitter, are well understood and routinely appearing in wine sensory. In contrast, information related to mouthfeel sensations is still relatively limited. Winemakers have worked hard to craft...

My thesis examines a total of fourteen characters from The Portrait of a Lady and The Turn of the Screw. Primarily, I have discovered an overwhelming pattern in these two works by Henry James; when characters make direct entrances--that is when they are not described or discussed in absentia by...
The cultivated potato, Solanum tuberosum L., has been one of the world’s most important food crops for more than 190 years and may become even more important to global food security in the coming 20 - 30 years. One of the world's largest growing health concerns is not just the...
Human alteration of natural landscapes leads to biodiversity loss, often from a combination of area effects and fragmentation effects. Smaller habitat patches support fewer species than large ones and incur additional consequences from isolation. Efforts to preempt biodiversity loss from insular habitat fragments are complicated by individualistic species responses and...
Phylogenetics benefits from using a large number of putatively independent nuclear loci and their combination with other sources of information, such as the plastid and mitochondrial genomes. To facilitate the selection of orthologous low‐copy nuclear (LCN) loci for phylogenetics in nonmodel organisms, we created an automated and interactive script to...
Changes in the type and amount of plant inputs can occur gradually, as with succession, or rapidly, as with harvesting or wildfire. With global change it is anticipated that both gradual and immediate scenarios will occur at increasing frequency. Changes in vegetation inputs alter the quality and quantity of soil...
As in many regions of the world, the shelf waters of the western United States have experienced large increases and high interannual variability in jellyfish populations in recent decades.
