School Mental Health Professionals' Perceived Efficacy Of Violence Prevention Programs And School Climate In Rural Schools, Jennifer Rotzal

Graduate Student Theses, Dissertations, & Professional Papers

In the United States, incidents of school violence increased 113 percent during the 2017-2018 school year from the 2016-2017 school year (Klinger, 2019). This increase in violence in schools makes the current movement for safer schools all the more critical. Although high-profile school shootings often obtain media attention, school violence remains a significant problem in the United States. Further, aside from the tragic but statistically rare school shootings, school violence encompasses several forms of physical violence, such as assaults; sexual violence, such as rape and sexual harassment; varying forms of bullying, including cyberbullying, and bringing weapons to school. The increase …

Ensemble Protein Inference Evaluation, Kyle Lee Lucke

Graduate Student Theses, Dissertations, & Professional Papers

The Protein inference problem is becoming an increasingly important tool that aids in the characterization of complex proteomes and analysis of complex protein samples. In bottom-up shotgun proteomics experiments the metrics for evaluation (like AUC and calibration error) are based on an often imperfect target-decoy database. These metrics make the inherent assumption that all of the proteins in the target set are present in the sample being analyzed. In general, this is not the case, they are typically a mix of present and absent proteins. To objectively evaluate inference methods, protein standard datasets are used. These datasets are special in …

Monitoring The Wetland Landscape: White-Faced Ibis (Plegadis Chihi) Breeding Habitat As A Model Assemblage, Shea P. Coons

Graduate Student Theses, Dissertations, & Professional Papers

Wetlands structure landscape biodiversity by providing critical habitat to numerous fish and wildlife species. However, climate change, growing human populations, and shifting land use practices strain limited water supplies that sustain wetlands in the semi-arid western US. Conserving a wetland network with prominent value to wildlife is paramount to ensure future security of habitat and ecosystem processes. Here, I use white-faced ibis (Plegadis chihi; hereafter ‘ibis’) breeding colonies as a model system to identify and monitor a landscape-scale wetland network across the semi-arid western US. Ibis serve an important role in marking ecologically important wetland networks because they require a …

Building Bridges: How Collaboration Is Addressing Wildlife-Vehicle Conflicts In Montana's Upper Yellowstone Watershed, Daniel Phelps Anderson

Graduate Student Theses, Dissertations, & Professional Papers

In my first semester of graduate studies at the University of Montana – Fall, 2019 – I was given an assignment from one of my professors to research a “landscape-scale” conflict of my choosing and compose a professional memo that could be sent to key influencers or stakeholders tied to the issue. Naturally, I directed my attention to a community I know and love, the Upper Yellowstone, and a conflict that is ubiquitous across the West: Wildlife-Vehicle Conflicts (WVCs).

In the pages that follow I describe how Yellowstone Safe Passages came to be, who is involved, and the steps we …

Collaborative Conservation And Backcountry Weed Control: A Case Study Of The Great Burn Proposed Wilderness, Christopher James Prange

Graduate Student Theses, Dissertations, & Professional Papers

Noxious weeds have become a management priority on public lands in the United States. Managing invasive weed populations in natural areas with complex ecosystems presents issues that need a systems-wide approach over long temporal and spatial scales. This broad-scale problem increasingly demands collaborative efforts. While collaborative conservation has become a tool in natural resource management during the 21^st century, it is less commonly applied in weed control in backcountry wilderness areas. Programs that have been initiated are understudied. Accordingly, this research was conducted through semi-structured interviews to gather perspectives of weed professionals involved in a collaborative backcountry weed program …

Super-Resolution Imaging Of Remote Sensed Brightness Temperature Using A Convolutional Neural Network, Kellen A. Donahue

Graduate Student Theses, Dissertations, & Professional Papers

Steady improvements to the instruments used in remote sensing has led to much higher resolution data, often contemporaneous with lower resolution instruments that continue to collect data. There is a clear opportunity to reconcile recent high resolution satellite data with the lower resolution data of the past. Super-resolution (SR) imaging is a technique that increases the spatial resolution of image data by training statistical methods on simultaneously occurring lower and higher resolution data sets. The special sensor microwave/imager (SSMI) and advanced microwave scanning radiometer (AMSR2) brightness temperature data products are well suited to super-resolution imaging, and SR can be used …

Albuquerque, Suzanne Joy Garcia Pino

Graduate Student Theses, Dissertations, & Professional Papers

This story is about living in Albuquerque, New Mexico in 2017 as a mixed-race woman with Hispanic, European, and Indigenous Mexican and Puebloan ancestry. Albuquerque seeks to understand how marginalized cultures become subsumed and ultimately lost by the dominate culture. As a child of mixed heritage, I am interested in the internalization of this cultural disappearance, and all the subtle yet profound choices my ancestors have made: my grandparents refused to teach Spanish to their children so they would fit in better with the whites, my Indian great grandfather fled Mexico, leaving behind his tribe and culture, never to return. …

Tennessee Williams: The Characters Are The Playwright, Peter A. Philips

Graduate Student Theses, Dissertations, & Professional Papers

Tennessee Williams was first and foremost a personage of the South, having been born, raised, and nurtured in the Mississippi Delta country. His early influences formed the concept of his “American Theatre.” He was a keen observer of people and places and wrote about the individuals he studied. He espoused the idea that as a homosexual he had the innate capability to write and appreciate various genders and sexualities, expressing himself as the character being developed in the moment of creation. Williams’s works, though containing moments of great humor, often trend toward darkness, becoming ever more pessimistic of human survival …

Witch Pamphlets, Tsea M. Francisconi

Graduate Student Theses, Dissertations, & Professional Papers

The witch hysteria that overtook Christian Europe during the Early Modern era inspired a mass paranoia over the conspiratorial belief that the Abrahamic religion’s personification of the world’s evils, also known as Satan, the Devil, demons, or Lucifer interchangeably, was attempting to rise up and cause harm to Christian communities during this time period. It was believed that in order to achieve this goal the Christian version of the Devil had been recruiting humans within Christian communities and turning these chosen humans into witches by granting them the ability to wield magical powers to spread their destruction, murder, and terror …

A Comparison Of Outcomes Of A Home-Based Cardiac Rehabilitation Program As An Alternative To Traditional Outpatient Phase Ii Cardiac Rehabilitation, Colton M.R. Crismore

Graduate Student Theses, Dissertations, & Professional Papers

Phase II outpatient cardiac rehabilitation (CR) is an intervention offered to patients that have been diagnosed with heart disease, undergone various procedures such as stenting or valve replacement, or to those with claudication diseases. Home-based cardiac rehabilitation (HBCR) is an alternative approach to traditional outpatient phase II CR, that is an emergent area of study with preliminary evidence showing in some outcomes that it approximates traditional CR. As there is current interest in the study of HBCR, this paper examines outcomes of mortality, risk factor modification, exercise capacity, and cardiac function to determine the extent to which this intervention may …

A Reintroduction Retrospective: Comparative Fisher (Pekania Pennanti) Survival And Prey Habitat Use In The Cascade Mountains Of Washington State, Tanner S.T. Humphries

Graduate Student Theses, Dissertations, & Professional Papers

Increasing human impacts on biodiversity highlight the global need for ecological restoration. For many wildlife species, reintroduction is necessary to re-establish populations in parts of their historic range where they have been extirpated. Reintroduction efforts are commonly used to help restore ecosystem integrity, but are often expensive, time consuming, and unsuccessful at generating self-sustaining populations. Thus, a more complete understanding of the factors affecting restoration success is important for ensuring successful outcomes and responsible stewardship. Fishers (Pekania pennanti) are one of the most commonly reintroduced carnivores in North America, but the success of such efforts is highly variable, …

Relating Streamflow Discharge To Surface Elastic Response Under Hydrologic Loading Using Single Gps Vertical Displacement And The Storage-Discharge Relationship At Local Watershed Scales, Noah B. Clayton

Graduate Student Theses, Dissertations, & Professional Papers

Uncertainties associated with climate change and increasing demands for water resources require better methods for estimating water availability at small to intermediate watershed scales (<1500 km²). Temporal changes in watershed storage and transport across various watersheds in the western U.S. were investigated using the hydrologic loading signal from GPS vertical displacements as a proxy for changes in watershed total terrestrial storage. GPS vertical displacement and streamflow discharge relationships were analyzed at daily to monthly temporal resolution. Stream connected storage changes were inferred using discharge using a first-order dynamical system model. Storage inferred from discharge, GPS vertical displacement and storage …

Estimating Wolf Predation Metrics, Patterns, And Dynamics Across Time And Space In The Multi-Prey System Of Yellowstone National Park, Matthew Caldwell Metz

Graduate Student Theses, Dissertations, & Professional Papers

Predation is a fundamental driver in ecology, structuring ecosystems across the globe. However, understanding the effects of large carnivore predation is limited by both the observation process and the shorter duration of many studies. I used data from 23 years in Yellowstone National Park to disentangle both the importance of wolf predation on prey, and the imperfect observation process of studying predation. I first used field observations to test whether a sexually-selected trait, antlers in male elk, deterred wolf predation. I found that antlers reduced predation risk, emphasizing the selective nature of predation. Next, I used GPS data and ground-based …

Evaluating The Effectiveness Of A Transgender-Affirmative Care Training On Healthcare Workers’ And Trainees’ Attitudes Toward And Knowledge Of Routine Care And Transition Support For Transgender Individuals, Oakleigh Marshall Reed

Graduate Student Theses, Dissertations, & Professional Papers

Objectives: Transgender individuals, often highly stigmatized and discriminated against, face challenging barriers regarding seeking routine- and transition-related physical and mental health care (James et al., 2016). What has been consistent throughout time is that contact as an intervention (i.e., personal contact, contact with educational materials, and/or contact with general media outlets) has been found to be associated with improved attitudes toward and knowledge of marginalized communities (Braun et al., 2017; Click et al., 2019; Reed, 2018; Stroumsa et al., 2019). The aim of the current study was to explore the impact contact with a transgender-affirmative care training may have on …

Polya: A Tool For Adjudicating Competing Annotations Of Biological Sequences, Kaitlin Carey

Graduate Student Theses, Dissertations, & Professional Papers

Annotation of a biological sequence is usually performed by aligning that sequence to a database of known sequence elements. When that database contains elements that are highly similar to each other, the proper annotation may be ambiguous, because several entries in the database produce high-scoring alignments. Typical annotation methods work by assigning a label based on the candidate annotation with the highest alignment score; this can overstate annotation certainty, mislabel boundaries, and fails to identify large scale rearrangements or insertions within the annotated sequence. Here, I present a new software tool, PolyA, that adjudicates between competing alignment-based annotations by computing …

A Review And Evaluation Of Techniques For Improved Feature Detection In Mass Spectrometry Data, Annika R. Tostengard, Rob Smith

Mass spectrometry (MS) is used in analysis of chemical samples to identify the molecules present and their quantities. This analytical technique has applications in many fields, from pharmacology to space exploration. Its impacts on medicine are particularly significant, since MS aids in the identification of molecules associated with disease; for instance, in proteomics, MS allows researchers to identify proteins that are associated with autoimmune disorders, cancers, and other conditions. Since the applications are so wide-ranging and the tool is ubiquitous across so many fields, it is critical that the analytical methods used to collect data are sound.

Data analysis in …

Soda: An Open-Source Library For Visualizing Biological Sequence Annotation, Jack W. Roddy, Travis J. Wheeler

Graduate Student Theses, Dissertations, & Professional Papers

Genome annotation is the process of identifying and labeling known genetic sequences or features within a genome. Across the various subfields within modern molecular biology, there is a common need for the visualization of such annotations. Genomic data is often visualized on web browser platforms, providing users with easy access to visualization tools without the need for installing any software or, in many cases, underlying datasets. While there exists a broad range of web-based visualization tools, there is, to my knowledge, no lightweight, modern library tailored towards the visualization of genomic data. Instead, developers charged with the task of producing …

Investigation Of Emissions And Chemistry Of Formic Acid And Acetic Acid In Wildfire Smoke, Catherine Elizabeth Wielgasz

Graduate Student Theses, Dissertations, & Professional Papers

Formic acid (HCOOH) and acetic acid (CH₃COOH) are two of the most ubiquitous organic acids in the atmosphere. Chemical transport models consistently underestimate HCOOH and CH₃COOH concentrations in environments including fire smoke, implying our incomplete understanding of their global budget. Emissions and secondary production of HCOOH and CH₃COOH within complex mixtures in fire smoke is uncertain.

I used measurements from the NSF/NCAR C-130 aircraft during the Western Wildfire Experiment for Cloud Chemistry, Aerosol Absorption, and Nitrogen (WE-CAN) campaign to investigate emissions and photochemical production of HCOOH and CH₃COOH from smoke plumes. First, …

Ecotoxicological And Physiological Effects Of Salinity On Amphibians, Brian James Tornabene

Graduate Student Theses, Dissertations, & Professional Papers

Salinity is a persistent anthropogenic contaminant that negatively effects freshwater species, communities, and ecosystems. High-salinity wastewaters from energy extraction (wastewaters) and road salts are major contributors to increased salinity (NaCl; sodium chloride), but most studies focus on effects of NaCl roads salts. Amphibians are particularly vulnerable to contaminants such as increased salinity because of their porous skin, dependence on freshwater, and poor osmoregulatory capacity. We investigated the relative effects of wastewaters and NaCl on three species of larval amphibians with acute toxicity experiments (Chapter 1). Effects of wastewaters on larvae were predominantly due to high concentrations of NaCl and both …

The Backfiring Effects Of Forced Political Allegiance In The Online World: The Case Of Preferred Pronouns On Twitter, Yin Lok Linus Chan

Graduate Student Theses, Dissertations, & Professional Papers

Political divisions in the United States have led to conflating political issues with political parties. People who possess a set of intercorrelated beliefs (e.g. pro-immigration, prochoice) are assumed to be liberal, while those who hold opposing intercorrelated beliefs are assumed to be conservative. Impression management research suggests that in the online world, minor cues on one’s social media profile that display political beliefs serve as indicators of people’s political ideology. While people are free to declare their political views on personal social media accounts, what happens when people perceive that they are forced to appear aligned with one political group …

Promoting Physical Activity Among American Indian Older Adults, Maja R. Pedersen

Graduate Student Theses, Dissertations, & Professional Papers

Background: Physical activity (PA) promotion is acknowledged as a critical component to improve public health among the growing population of older adults in the U.S. American Indian and Alaska Native (AIAN) older adults experience disproportionately high rates of chronic disease and disability compared with non-Hispanic White peers, and demonstrate lower levels of PA, indicating a need for examination of unique factors influencing their PA behavior.

Purpose: This study revealed the current state of PA intervention research among AIAN older adults in the U.S. and utilized best practices to identify factors that can influence the development, adaptation, and implementation of PA …

Lifeglows Through The Anthropocene: Development Of The Radical Imagination And Response-Ability Within Superhero Comics, Reed G. Puc

Graduate Student Theses, Dissertations, & Professional Papers

Scholars such as Amitav Ghosh, Timothy Clark, and Timothy Morton emphasize the importance of and challenge within the task of representing the power, scope, and scale of climate change in art and literature. These interrogations often emphasize the failures of extant works to animate their viewers towards action in a time of environmental crisis, but struggle to find any work that meets their expectations. This ‘game-over’ attitude, I argue, is the direct result of the cruel optimism present in the current scholarship’s attachment to ‘traditional’ forms of art and literature. By interrogating the conclusions Ghosh reaches about the novel’s function …

Gender And Sexuality Alliance Advisors' Perceptions Of Self-Efficacy And Social Emotional Competency: An Exploratory Study, Kelly Marie Davis

Graduate Student Theses, Dissertations, & Professional Papers

Background: Literature consistently demonstrates mental health disparities among sexual and gender minority (SGM) youth due to their unique experiences of discrimination, victimization, and rejection on the basis of their sexual and/or gender identity. Findings from the resilience literature highlight the importance of emotion regulation skills, supportive communities, and a relationship with at least one supportive, stable adult in mitigating risk and thriving despite adversity. Relationships with adults confer tremendous benefit for youth and provide opportunities for youth to learn important social and emotional skills. However, due to the rates of family and school rejection that SGM youth often experience, they …

The Road To Self-Support: Vocational Rehabilitation And The Associational State, 1917-1945, William Jared Norwood

Graduate Student Theses, Dissertations, & Professional Papers

“The Road to Self-Support: Vocational Rehabilitation and the Associational State, 1917-1945” traces the origins and development of the Civilian Vocational Rehabilitation (CVR) program from its inception in 1920 until the conclusion of the Second World War. Rapid industrialization and the fallout of the First World War handed the nation a large amount of people with disabilities, which drew on already strained state and local welfare relief. The project examines the interwar period and finds it to be a battleground of differing governing strategies over how best to solve America’s growing level of disabled workers. The project argues that policymakers settled …
