Graduate Student Theses, Dissertations, & Professional Papers

Francis’s grandpa taught her how to wrestle alligators. By the time Francis was sixteen, she could hold her own, but all it takes is one gator. Just one gator who almost gets the best of you, and suddenly you’ve got a dead animal; somebody’s getting stitches; you’re getting haunted by the ghost of the alligator you just killed; and your mom’s making you move to Charleston to attend a swanky prep school where the kids don’t wrestle gators, but surviving the gossip is even harder.

The Existential Challenges Of Cyberspace, Sean Cleary

Graduate Student Theses, Dissertations, & Professional Papers

Cyberspace is an emergent environment that has come to facilitate a growing range of human activity. Here, information is tightly woven, freed of unnecessary context and always within reach. This thesis explores the existential challenges that arise from increased engagement in this space and offers solutions informed by Henry Thoreau and Søren Kierkegaard. Section One offers an ontological account of cyberspace and describes its relationship to what I call the lifeworld. Section Two further examines the relationship drawn out in Section One, introduces the challenge of foreground saturation and appeals to Thoreau for solutions. Section Three introduces the concept of …

Randomly Perturbed Graphs And Rainbow Connectivity, John Arthur Finlay

Graduate Student Theses, Dissertations, & Professional Papers

In this work we explore randomly perturbed graphs; that is, for an arbitrarily dense graph H we add a set R consisting of m edges randomly to create a graph G. We then randomly color the edges of G with r colors. We prove, for r ≥ 5 and m a large enough constant, that between any two vertices in G there exists a rainbow path and thus G is rainbow connected. This result confirms a conjecture of Anastos and Frieze [How many randomly colored edges make a randomly colored dense graph rainbow Hamiltonian or rainbow connected?, J. Graph Theory …

A Thinking Person's Guide To Immigration And Environmental Racism At The Us - Mexico Border, Emma H. Kiefer

Graduate Student Theses, Dissertations, & Professional Papers

In recent years, more attention has been paid to the immigration crisis at the US-Mexico border thanks in part to the strict immigration restrictions from the Trump administration, such as the family separation policy. Immigration remains a widely misunderstood issue and arguments against increased immigration are often laced with racist stereotypes and perceptions that find their roots in centuries of US policy, court cases, and administrative rules. Similarly, the concept of environmental racism can be difficult for the American public to understand when modern-day racism alone has become more insidious. Intersectionality, a concept coined by sociologist Kimberlé Crenshaw, asks us …

A Machine Learning Algorithm Improves Surface Freeze-Thaw Classification, Fredrick Bunt

Graduate Student Theses, Dissertations, & Professional Papers

The frozen or thawed state of the land surface is an important factor affecting a wide range of natural processes such as surface water movement, the carbon cycle, and ecosystem development. It is also important for human endeavors such as permafrost engineering and agricultural planning. This makes having an accurate record important. The Freeze-Thaw (FT) Earth System Data Record (FT-ESDR) is a global, daily product that strives to be a reliable record of the FT ground state. In its current form, the FT-ESDR uses annual regression analysis of reanalysis surface air temperatures (SAT) and brightness temperatures (Tb) at each grid …

Lasso: Listing All Subset Sums Obediently For Evaluating Unbounded Subset Sums, Christopher N. Burgoyne, Travis J. Wheeler

Graduate Student Theses, Dissertations, & Professional Papers

In this study we present a novel algorithm, LASSO, for solving the unbounded and bounded subset sum problem. The LASSO algorithm was designed to solve the unbounded SSP quickly and to return all subsets summing to a target sum. As speed was the highest priority, we benchmarked the run time performance of LASSO against implementations of some common approaches to the bounded SSP, as well as the only comparable implementation for solving the unbounded SSP that we could find. In solving the bounded SSP, our algorithm had a significantly faster run time than the competing algorithms when the target sum …

Battles Of The Mind: The Reaction Against Progressive Education, 1945-1959, Ben Yturri

Graduate Student Theses, Dissertations, & Professional Papers

This thesis discerns the relationships between three interrelated movements of the post-war period (circa 1945-1959): the overwhelming concern among leading intellectuals regarding the relationship between the individual and society, the post-war debates over education, and rising religious observance. Following WWII, the nation’s leading scholars and social critics addressed the most important problem facing the country and, for that matter, the world: how to avoid totalitarianism. Almost naturally, such anxieties influenced new debates over education. Broadly speaking, these controversies involved two related disputes over the efficacy of progressive education and the proper relationship between church and state. After World War II, …

Conserving And Sharing Freshwater In The West, Kelsea Harris-Capuano

Graduate Student Theses, Dissertations, & Professional Papers

There are infinite stories to be told about water in the West. As an essential and finite resource, countries, states, tribal nations and neighbors must figure out how to manage this shared resource, whether for ecosystem sustainability, agricultural, household, or recreational use.

He, She, They, Other: An Examination Of Gender Associations With The Chatelaine In The Anglo-Saxon Culture, Dane A. Williams

Graduate Student Theses, Dissertations, & Professional Papers

The purpose of this paper is to study the chatelaine as a marker of gender attribution and overall usage within the Anglo-Saxon culture. Chatelaines are artifacts used to suspend multiple items to be employed for such purposes as grooming, tools, or keys and have been used widely from the Roman occupation of England during which it was used by all genders, to the Ninth Century when it was primarily used by women. As such, it is asserted that a single artifact should not to be solely relied upon to assign a gender identity to a burial, that these should be …

Determining Spatial Controls On Snow Isotopic Signature And Tracing The Snowmelt Pulse As It Moves Through Two Montane Catchments, Jenna K. Rolle

Graduate Student Theses, Dissertations, & Professional Papers

In this study, we investigate the spatial and temporal distribution of stable isotopes of oxygen and hydrogen in water across two mountainous catchments in west-central Montana to trace the input of snow to local soil, bedrock aquifers, and streams. Snowpack and snowmelt samples were collected throughout the winter season at ten sites selected to encompass a range of elevation, aspect, slope angle and hillslope position. Soil and bedrock wells at five of the ten sites were sampled after the initial snowmelt pulse and stream samples were collected weekly at the outlets of both catchments to trace the timing and partitioning …

Sensitivity Of Lidar Derived Fuel Cells To Fire Modeling At Laboratory Scale, Anthony Albert Marcozzi

Graduate Student Theses, Dissertations, & Professional Papers

Computational models of wildfires are an important tool for fire managers and scientists. However, fuel inputs to wildfire models can be difficult to represent with sufficient detail to be both computationally efficient and representative of observations. Recent advances in fuel mapping with airborne and terrestrial laser scanning (LIDAR) techniques present new opportunities to capture variation in fuels within a tree canopy and on a landscape. In this paper, we develop a technique for building 3D representations of vegetation from point clouds created by Terrestrial Laser Scans (TLS). Our voxel based approach can be extended to represent heterogeneous crown fuels as …

Using Multiple Environmental Tracers To Estimate Field-Scale Longitudinal Dispersivity, Casey L. Kleppel

Graduate Student Theses, Dissertations, & Professional Papers

In this study, we seek to reduce parameter uncertainty in groundwater modeling systems, particularly in reactive transport models, by quantifying effective field-scale longitudinal dispersivity using anthropogenic environmental tracers. We generate synthetic aquifer fields and model transport of atmospheric tracers and test whether tracers can be used to determine an effective aquifer-scale dispersion coefficient. We generate synthetic datasets by simulating transport of chlorofluorocarbons (CFC11, CFC12, CFC113), sulfur-hexafluoride (SF₆) and tritium (³H) with input functions derived from known atmospheric concentrations, through a three-dimensional, stochastic, heterogeneous synthetic aquifer developed using sequential Gaussian simulation using the PFLOTRAN reactive transport model. …

Re-Modeling The Interior: Spatial Methods And Policy Revisions To Improve Inventory And Designation Of Blm’S Areas Of Critical Environmental Concern, Amy H. Katz

Graduate Student Theses, Dissertations, & Professional Papers

The Bureau of Land Management (BLM) manages a vast amount of public land in the western United States, most of which they currently manage for multiple uses. Specific conservation and management of these lands could mitigate climate change impacts and contribute to the global initiative to conserve 30 percent of lands and waters by 2030. Particularly, the agency can achieve this through more effective administration of Areas of Critical Environmental Concern (ACEC), a designation that is prioritized under the Federal Land Policy and Management Act (FLPMA). To do so requires updated regulations that set clear parameters around inventory and designation, …

Sunbaby, Katelyn Eva Garcia

Graduate Student Theses, Dissertations, & Professional Papers

Above all else, Sunbaby is a project concerned with that which is passed down from a mother to her daughters. Less interested in writing into the center of violent acts, this series of poems aims instead to consider all the things – both physical and psychological – that exist of the edges of violence. What happens to a body in the wake of violent acts? What informs the trauma of families? These are questions Sunbaby asks its reader to grapple with.

Set to background of the desert and mountain West, Sunbaby lingers on bodies (human and other) subjected to environmental …

For The Love Of Language: Microrituel In The Socialization Of Language Teachers, Rebekah Morgan Skoog

Graduate Student Theses, Dissertations, & Professional Papers

Language and social interaction have been determined to be intricately linked. Over the past century, studies surrounding how to learn languages have shifted the conversation on how to teach them. With the introduction of Hymes’ (1971) Communicative Competence into pedagogical literature, learning language within social context replaced the formally grammar based, traditional methods. During the early 1960’s the American Council for the Teaching of Foreign Language led the charge on providing standards and learning objectives to shift language learning towards a more integrated and communicative approach. However, based on the research of Celce-Murcia (2007), Aguilar (2007), and Ishihara & Cohen …

The Syndemic Landscape: A New Paradigm For Montana Suicide Prevention Grounded In Agricultural Renewal, Emory Chandler Padgett

Graduate Student Theses, Dissertations, & Professional Papers

Montana has had one of the highest suicide rates in the nation for half a century, and since 2000, it has risen almost 50%. Despite suicide’s alarming persistence in the state, there has been minimal academic study of suicide or mental health specifically in Montana, so this thesis attempts to answer a few questions: Why does Montana have such a high suicide rate? Is there something culturally, historically, or socially unique about Montana that contributes to suicide? Are current prevention efforts helpful, harmful, or lacking? Could a consideration of culture and land benefit an understanding of suicide in Montana? What …

Spatial Behavior, Foraging, And Population Dynamics Of A Subarctic Ungulate, Elizabeth (Libby) Parr Williamson Ehlers

Graduate Student Theses, Dissertations, & Professional Papers

The concept of density-dependence is foundational to our understanding of the ecology and management of large herbivores. As the abundance of large herbivores increases, competition for high-quality resources increases and animals select for lower-quality foods potentially resulting in reduced vital rates that cause declines in population growth. What remains unclear is how foraging at finer scales, like the ‘bite’, translates to demography. This is difficult because it’s challenging to scale bite-level foraging to population-levels. I test the fine-scale foraging mechanisms of density dependence in a large subarctic herbivore, Barrenground caribou (Rangifer tarandus granti). The nutritional landscape for arctic herbivores is …

Relationships Between Water, Sediment, Basal Resources, And Aquatic Insects In A Mine-Contaminated River On A Longitudinal And Habitat Patch Scale, Chelsea A. Wisotzkey

Graduate Student Theses, Dissertations, & Professional Papers

It is well established that aqueous exposure and dietary exposure both lead to the accumulation of metals and metalloids in aquatic organisms living in a contaminated environment, but the relative contribution of each remains unclear. To examine how a contamination gradient affects patterns of metal(loid)s among periphyton, BPOM (benthic particulate organic matter), water, and sediment, we collected samples from multiple sites across a 210km stretch of the mine-contaminated Upper Clark Fork River, Montana. To investigate metal(loid) accumulation patterns among basal resources and aquatic insects, we collected samples of periphyton, BPOM, and larval insects from discrete habitat types at a single …

Traditional Vs. Home-Based Phase Ii Cardiac Rehabilitation In A Rural Setting: A Retrospective Study, Cassie Marie Reisdorph

Graduate Student Theses, Dissertations, & Professional Papers

This dissertation addresses the following questions: 1) the impact of three environmental conditions (altitude, heat, and woodsmoke exposure) on the blood oxidative stress response to exercise; 2) the effect of exercise-based cardiac rehabilitation programs (home-based, HBCR; traditional, TCR) on health outcomes in those who have experienced a cardiovascular event and/or severe diagnosis resulting in referral to cardiac rehabilitation. Study 1: Examine effects of lab-simulated hypobaric and hypoxic conditions on oxidative stress during a 4-hour recovery period after 1-hour of cycling (70% watts max). Exercise increased markers of antioxidant status (TEAC, FRAP) and lipid damage (8-ISO) (p<0.05). No effects of hypobaria and hypoxia were observed. Study 2: Compare the blood oxidative stress response to an exercise tolerance trial (1-hour, 50% W_peak) in hot …

The Combination Of Tlr7/8 And Tlr4 Adjuvants In An Influenza Vaccine Produce Unique Antigen-Specific Adaptive Immunity And Protect Against Lethal Heterologous Influenza Challenge, Shelby Lynn Cole

Graduate Student Theses, Dissertations, & Professional Papers

Influenza virus infection is a global health concern resulting in death and illness each year, which disproportionally effects high-risk individuals. While there are several approved vaccines for seasonal influenza, there are some limitations to consider: current vaccines provide minimal cross protection against seasonally drifted influenza subtypes, influenza vaccine strains change each year, requiring timely manufacture of a new vaccine. Thus, vaccines capable of inducing a more robust and broadly protective immune response to multiple influenza subtypes remains a critical unmet need. Adjuvants and novel delivery systems are an interesting and promising avenue of exploration for enhancing and broadening seasonal influenza …

Large Carnivore Recolonization Reshapes Population And Community Dynamics In The Rocky Mountains: Implications For Harvest Management, Tyler James Clark

Graduate Student Theses, Dissertations, & Professional Papers

Large carnivores are re-colonizing their historical range globally, following decades of systematic eradication. The subsequent expansion of large carnivore populations is creating complex predator-prey interactions by trophically upgrading previously simpler food webs. Overlap between large carnivore and human range expansion is increasing human-carnivore conflicts, with many calling for large carnivore management to mitigate predation on harvested ungulates. However, the complexity of food web interactions in trophically upgraded systems coupled with independent management strategies for each species makes it difficult to determine what are optimal management strategies in these systems. These issues are further complicated by expectations of harvested ungulate densities …

2020 Lgbtq Specific Substance Use Service Survey: A Study On The Availability And Perceived Helpfulness Of Treatment Programs, Chonghui (Gabriella) Ji

Graduate Student Theses, Dissertations, & Professional Papers

Health disparities researchers have identified elevated rates of difficulties among gender and sexual minorities (GSM). In addition to a higher rate of general mental health issues, there is also a higher prevalence rate of substance misuse among GSM individuals when compared to the general population. Specific issues, such as stigma and oppression faced by GSMs, might have a direct linkage with the higher prevalence rate and might also impact treatment outcomes. To understand the specific factors that lead to substance misuse, as well as to understand the unique patterns of treatment-seeking and adherence among GSM clients, the development and dissemination …
