Understanding Trauma Awareness And Communication Competency In Athletic Training: A Mixed Methods Inquiry, Adrienne Anne Tauses

Graduate Student Theses, Dissertations, & Professional Papers

There has long been a link between stress and injury in athletes. Even so, athletic injuries are often viewed as primarily performance issues which ignores potential underlying psychological contributors to the injury. Research has shown that while athletic trainers have some training in psychological competencies, they lack awareness of trauma and self-efficacy in engaging in difficult conversations with athletes. Review of the literature will address the gaps in athletic training, and the potential of athletic trainers in supporting physical and mental health outcomes in athletes (Cormier & Zizzi, 2015; Cutler & Dwyer, 2020). Addressing the whole person within a sample …

Promoting Well-Being In Schools: The Effects Of A Happiness Workshop On Educators And Other School Personnel, Robert J. Ryan

Graduate Student Theses, Dissertations, & Professional Papers

Educators throughout the United States report high levels of mental distress, anxiety, depression, and stress and difficulties with physical health. Educational systems have limited ability to address the well-being of faculty and staff in primary and secondary schools. Existing interventions are not always adequate and often do not reach the majority of educators who are facing challenges in the aforementioned areas of wellness. Positive psychology interventions and workshops have demonstrated their efficacy in promoting well-being with different populations. In this quantitative, quasi-experimental, pretest-posttest study, I studied the effects of a brief happiness for educators workshop on participants’ well-being. The happiness …

Blood And Oil: How Vampiric Literature Bolsters Big Oil’S Power, Sarah Marie Demond

Graduate Student Theses, Dissertations, & Professional Papers

This thesis examines the relationship between blood and oil, that is, the multitude of ways in which the petromodernity industries harvests and threatens vitality. The introduction of this thesis is concerned tracking how petromodernity is a byproduct, offspring, or extension of colonialism. In this way, petromodernity can be thought about as “petro-colonialism.” Ursula K. LeGuin’s “Carrier Bag Theory of Fiction” informs the argument that the way thay petro-colonialism came to be and also maintains itself is by utilizing the “killer story.” This thesis also employs autorheoretical techniques informed by Lauren Fournier to show how petro-colonialism or “oiliness” sticks to its …

Variation In Body Composition In Deer Mice: The Biogeography And Ecophysiology Of Energy Allocation, Cole Joseph Wolf

Graduate Student Theses, Dissertations, & Professional Papers

Body composition, the percent of lean and fat mass, is a snapshot of an individual’s energetic state at a moment in time. Wild organisms should allocate energy to optimize fitness, so tracking changes in body composition provides a window into how priorities may shift throughout the year or across environments. While seasonal variation in body composition is wellcharacterized in systems such migrating birds (Scott et al. 1994) and hibernating mammals (Hellgren 1998), much less is known about how this trait varies across species ranges and thus how organisms modify their body composition and to meet local environmental challenges. For my …

Wet Specimen, Abigail Lee Raley

Graduate Student Theses, Dissertations, & Professional Papers

Cystic fibrosis is a condition which thickens the mucus throughout the body of the afflicted patient. Bob Flanagan, in his book The Pain Journal, ventures to record that sort of physical experience, as it pertains to the daily practices of his art, leading up to his death. Flanagan expounds on given relationships between his sadomasochistic performance art and the pain of his body in his poem “Why.” Richard Siken, too, in his book Crush, explores the embodied violence of gay lust, love, and obsession. WET SPECIMEN finds itself amongst these traditions, as it ventures to explore the animality …

Greater Sage-Grouse In A Grazed Landscape: Habitat Selection, Demographic Rates, And Population Trends In Central Montana, Jennifer Evans Helm

Graduate Student Theses, Dissertations, & Professional Papers

Greater sage-grouse (Centrocercus urophasianus) abundance has declined across the species’ range due to habitat loss, degradation, and fragmentation. To address this decline, information is needed to guide habitat conservation priorities and population management efforts. This includes information about patterns of habitat selection at multiple spatial scales, habitat and land use variables that affect demographic rates, and population trend estimates. We collected ten years of data (2011-2020) on sage-grouse demographic rates and habitat selection, as well as on vegetation and livestock grazing patterns, to address these topics. We were specifically interested in the effects of a rotational grazing system implemented through …

Supervised Cancer Rehabilitation: Applications For Utilizing Existing Cardiopulmonary Rehabilitation Facilities For Cancer Patients And Survivors, Nancy A. Condit

Graduate Student Theses, Dissertations, & Professional Papers

Currently, the NIH reports there are approximately 18 million Americans with a history of cancer. Cancer statistics are projected to rise to 22.1 million by 2030. In addition to cancer, cardiovascular diseases are globally the leading causes of mortality and morbidity. The body of research in this area clearly demonstrates that greater amounts of physical activity correspond with a lower risk of cancer recurrence and all-cause mortality, including cardiovascular disease (CVD). Exercise rehabilitation success in cancer patients, both during and after treatment, is limited by several barriers, including the lack of facilities, trained personnel and financial resources. In response to …

Federal Funding Statutes And State-Federal Wildlife Authority: Did Congress Demonstrate A Preference For State Wildlife Management Authority With Pittman-Robertson And Dingell-Johnson?, James Vaughan Branch

Graduate Student Theses, Dissertations, & Professional Papers

The Federal Aid in Wildlife Restoration Act of 1937 now known as Pittman-Robertson and Federal Aid in Sport Fish Restoration Act of 1950 now known as Dingell-Johnson are federal statutes which stand as the original and perhaps most significant federal funding statutes supporting state wildlife conservation and management. Congress’s decision to pass these statutes may be argued to be a prima facie endorsement of state wildlife agencies (SWA) as the primary managers of wildlife since each statute dedicated substantial federal excise revenue to SWAs. We hypothesized we would find consistent evidence in favor of primary state management authority over wildlife. …

Modifying Lysosomal Cholesterol Or Potassium Channel Activity Prevents Silica-Induced Inflammation, Rebekah Louise Kendall

Graduate Student Theses, Dissertations, & Professional Papers

Chronic inflammation contributes to a number of diseases, driven by NLRP3 inflammasome activity and the lack of resolution. Silicosis is one such disease, brought on by the unresolved inflammation caused by inhaled crystalline silica particles of sufficiently small size. These particles are taken up by alveolar macrophages to protect the fragile alveolar spaces. Silica particles interact with phagolysosomal membranes through nearly free silanol moieties and disrupt the lipid order of the lysosomal membrane thereby causing permeabilization. This permeabilization (LMP) leads to the release of proteases including Cathepsin B that promote the assembly and activation of the NLRP3 inflammasome. The inflammasome …

Evaluating Nurse Engagement With And Opportunities For Human Papillomavirus (Hpv) Vaccine Promotion In Montana, Juthika Jayendra Thaker

Graduate Student Theses, Dissertations, & Professional Papers

Purpose: Parental vaccine hesitancy is a known driver of sub-optimal vaccine uptake in the United States.1 Even though a study analyzing parental responses in National Immunization Survey-Teen found that HPV vaccine hesitancy has slightly declined (69% in 2010 v/s 63% in 2019) over the years, only about 52.6% of adolescents in Montana had received all the required doses of the HPV vaccine series in 2021.2,3 Nurses are at the forefront of healthcare provision and possess a unique ability to influence parental vaccine decisions.5 By listening to and addressing parents' concerns about immunizations, nurses can dispel misinformation and help change parents' …

Causes Of Low Leaf-Shredding Insect Diversity In Neotropical Streams, Pavel Ernesto Garcia Soto

Graduate Student Theses, Dissertations, & Professional Papers

Biological diversity peaks in tropical regions followed by a steady decline towards the poles. It is a pattern in γ-diversity that sometimes explains latitudinal patterns in local assemblages (α) and their species turnover (β), which suggests that similar ecological mechanisms might be operating at different latitudes. However, not all taxa have more species towards the equator. Aquatic shredder insect richness peaks in temperate streams relative to tropical streams, where local aquatic shredder insect assemblages have low α-diversity. Three mechanisms have been proposed as factors structuring aquatic shredder insect assemblages in tropical streams, leading to shredder assemblages with low α-diversity, 1) …

Weathering The Storm: The Journey Of Healing From Sexual Trauma, Hana Shewamoltot Meshesha

Graduate Student Theses, Dissertations, & Professional Papers

Individuals identifying as members of an underrepresented group face a higher risk of sexual violence (RAINN, 2020; Rosay, 2016; Smith et al., 2017). Encountering sexual violence is associated with physical and mental health issues that impact the wellbeing of survivors. Developing a theory to explain the healing responses to sexual trauma helps both survivors and those providing support gain knowledge about potentially transferable healing strategies. This grounded theory study was guided by a central question: what is the experience and process of surviving sexual trauma for individuals in underrepresented groups? Six adult survivors of sexual trauma identifying as members of …

Structural Properties Of The Interactions Between Cytochrome C And Cardiolipin, Ariel Kristine Frederick

Graduate Student Theses, Dissertations, & Professional Papers

The interaction between cytochrome c and cardiolipin is known to be essential for the onset of apoptosis: cytochrome c becomes competent for peroxidase activity due to the presence of reactive oxygen species and oxidizes cardiolipin, ultimately resulting in mitochondrial membrane pores that allow cytochrome c to escape into the cytosol and form the apoptosome complex. As such, understanding this reaction is critical to understanding the mechanisms of programmed cell death. Despite this, many components of this interaction are still under debate. Examples of this include which components of cytochrome c structure are responsible for the large differences in peroxidase activity …

Beaver Dam Analogs (Bdas) Alter Carbon Pools, Fluxes, And Concentrations Of Intermountain Headwater Streams, Hilary Schultz

Graduate Student Theses, Dissertations, & Professional Papers

Beaver dam analogs (BDAs) have emerged as a climate adaptation and restoration strategy for water resource management in the drought-prone Western U.S., yet the focus has been on their influence on water quantity, overlooking effects on broader ecological components. By increasing water residence time and facilitating sediment retention, BDAs have the potential to influence carbon pools, fluxes, and concentrations. To examine the influence of BDAs on instream and riparian organic C and trace gases, we studied three intermountain headwater streams restored with BDAs two years after restoration during the summer of 2021. We found that there were subtle differences in …

Electric Momentum: Dynamics Of Transportation Electrification And Stories From The Road, Amelia Liberatore, Amelia R G Liberatore

Graduate Student Theses, Dissertations, & Professional Papers

The climate is undeniably changing. The Intergovernmental Panel on Climate Change (IPCC) published yet another report this year outlining how extreme weather, brought on by our use of Earth's resources, causes loss of nature and human life around the world. The summer of 2023 broke records for high ocean temperatures and melting polar ice, and abnormally potent floods and fires touched all corners of the Earth. Industrial production of goods, and the personal choices that purchase them, are responsible for massive amounts of greenhouse gases (GHG), including carbon dioxide and methane. GHG emissions thicken the Earth's atmosphere and continue the …

The Politics Of Abundance: American Philanthropy And The Political Economy Of Food In The Twentieth Century, Elizabeth Berit Barrs

Graduate Student Theses, Dissertations, & Professional Papers

“The Politics of Abundance: American Philanthropy and the Political Economy of Food in the Twentieth Century” uses food aid as a lens to understand how philanthropy became a significant new force in the twentieth-century political economy, both in the US and in the projection of American power abroad. I argue that US-based international food philanthropy joined with the state and the full breadth of the American food industry to structure the political economy of food in the twentieth century and to export it globally, impacting how much of the world produces and consumes food. Voluntary agencies and foundations provided a …

High-Frequency Observations Of Riverine Inorganic Carbon Variability Using In Situ Autonomous Sensors, Qipei Shangguan

Graduate Student Theses, Dissertations, & Professional Papers

Rivers and streams actively metabolize, emit, transport and store carbon of various forms received from terrestrial environments. Our current understanding of how rivers and streams contribute to the global carbon cycle remains limited, however, in part due to high temporal variability and complexity of inorganic carbon chemistry. In situ autonomous chemical sensors provide powerful tools to observe changes in rivers and streams and enable development of CO2-specific models to quantify riverine processes. In many aspects, our ability to utilize high-frequency sensor measurements remains limited.

This dissertation aims to improve our understanding of inorganic carbon cycling through sensor technology and numerical …

Climatological, Hydrological, And Economic Analysis Of Agriculture In Montana And The Western U.S.A., Zachary H. Lauffenburger

Graduate Student Theses, Dissertations, & Professional Papers

Many studies have addressed the impact of climate on agriculture; however, fewer studies addressed how farmers adapt to climate change, to what extent implementation of adaptation strategies mitigates economic losses or alters the hydrologic system. Analyses of how historical climate affected not only farmer decision making, but also the economic and hydrological consequences of farmers’ adaptations to climate variations, and projections of the spatiotemporal climatic regimes at finer regional scales are critical for aiding in actionable climate change adaptations. This dissertation helps fill knowledge gaps on the impacts of climate change in rural regions of the agricultural western U.S.A. and …

Evaluating The Sensitivity Of Crustal Deformation To Bedrock Hydrology In A Mountain Watershed, Brett J. Oliver

Graduate Student Theses, Dissertations, & Professional Papers

We evaluate the sensitivity of Earth's elastic deformation to groundwater hydraulic diffusivity using coupled groundwater and elastic deformation models. Seasonal changes in terrestrial water storage cause deformation to the Earth’s crust and deeper interior that is within the observational capacity of GPS instruments. We couple finite difference groundwater simulations with geodetic forward models of crustal displacement to investigate the ability of geodetic deformation to constrain bedrock hydrologic properties. We use MODFLOW-2005 to simulate seasonal changes in groundwater flow and storage, and then use the LoadDef elastic deformation model to forward model surface displacement caused by the change in terrestrial water …

Fundamental Investigation On Anion Binding Employing The Hydrogen Bond Enhanced Halogen Bond, Jiyu Sun

Graduate Student Theses, Dissertations, & Professional Papers

Noncovalent interactions play a critical role in chemistry and biochemistry. Understanding how to modulate closely situated noncovalent interactions is of utmost importance in the design of functional materials, supramolecular assemblies, pharmaceuticals, and catalysts. Over the past two decades, there has been a significant surge in research and applications on halogen bonds, driven by their exceptional properties such as high directionality and unique tunability when compared to hydrogen bonds. Taking inspiration from nature and other synthetic anion-binding receptors that effectively employ multiple noncovalent interactions in a concerted manner, we have developed an innovative preorganization strategy termed the "Hydrogen Bond Enhanced Halogen …

Liberal Men, Rational Kings: The Democratization Of Sovereign Individualism, Austin Daniel Ladd

Graduate Student Theses, Dissertations, & Professional Papers

Theoretical traditions are reactionary insofar as they are attempts to remedy deleterious conditions generated by certain political, cultural, and economic situations characteristic of a particular polity at a particular time. Using this lens, I investigate the principles of classical liberalism and suggest that they are specifically designed to solve the problems that animated the world of divine right, essentially functioning as transitional mechanisms pulling society towards liberal social contract regimes and away from antiquated feudal institutions and absolute monarchy. I craft a narrative that demonstrates that the main problem all of them coalesce to solve is individualism which, under divine …

Seedy Business: Unveiling Fruit-Frugivore Interactions In Loango National Park, Gabon, Diandra Mary Lewis

Graduate Student Theses, Dissertations, & Professional Papers

Fruit-frugivore interactions within forest ecosystems are intricate and are critical determinants of community structure, function, and composition. Increasing anthropogenic impacts on biodiversity in general and forests in particular highlight the need to better understand these plant-animal relationships. This thesis focuses on connections between fruit-bearing plants and the animals that eat their fruits in a relatively undisturbed rainforest in Gabon. The work combines two studies: one scrutinising fruit trait clustering, and the other delving into the difference between using dispersers versus consumers in seed dispersal networks.

In chapter 1, we focused on fruit traits and how they group together in order …

Impacts Of Climate And Wildfire On Western Larch Regeneration, Spencer T. Vieira

Graduate Student Theses, Dissertations, & Professional Papers

Fire plays a critical role in forests of the western United States (US), but as wildfire and climate deviate from historical patterns, increasing fire activity may significantly alter forest ecosystems. To understand the impacts of changing climate and wildfire activity on conifer forests, we studied the impact of wildfire and annual post-fire climate on western larch (Larix occidentalis) regeneration. We destructively sampled 1651 seedlings from 57 sites within 32 fires that burned at moderate or high severity from 2000-2015 in the northwestern US. Using dendrochronological methods, we estimated germination years of seedlings to calculate annual recruitment rates. We …

Genetic And Environmental Contributions To Wolbachia-Induced Cytoplasmic Incompatibility, Kelley Van Vaerenberghe

Graduate Student Theses, Dissertations, & Professional Papers

Maternally-transmitted Wolbachia infect the cells of most insect species, but their frequencies in host populations vary. While much of their success can be attributed to their ability to manipulate host reproduction, these manipulations are context-dependent, varying due to several biotic and abiotic factors. Wolbachia’s most common manipulation, cytoplasmic incompatibility (CI), is a conditional sterility phenotype where male-female host compatibility depends on their infection status. Specifically, CI occurs when infected males produce modified sperm that cause increased embryonic lethality unless the female carries a similar infection. Rescuing their eggs from CI increases the relative fitness of infected females, promoting Wolbachia spread …

Impacts Of Conifer Removal On Songbird Density, Reproductive Output, And Habitat Selection, Elise Catherine Zarri

Graduate Student Theses, Dissertations, & Professional Papers

Restoration of anthropogenically altered habitats is vital to protect biodiversity and prevent species extinction as landscapes are increasingly altered, degraded, and lost. However, restoration is often done without a full understanding of its impact on biological communities. Lack of knowledge can lead to unintended negative consequences for some species restoration was intended to benefit. Woody plant encroachment is a form of habitat alteration occurring in grasslands and shrublands around the globe, driven by anthropogenic shifts in disturbance regimes. One example is conifer expansion into historically widespread sagebrush communities. Sagebrush restoration through conifer removal has become a common strategy to aid …

Predicting Gene Flow Corridors And Wildlife Health Using Landscape Genomics And Non-Invasive Metagenomic Monitoring: Investigation Of Elk (Cervus Canadensis) In The Greater Yellowstone Ecosystem, Samuel B. Pannoni

Graduate Student Theses, Dissertations, & Professional Papers

This work develops and applies novel methods for metagenomic and landscape genomic (LSG) investigation of wildlife populations, specifically in Rocky Mountain elk (Cervus canadensis) in the Greater Yellowstone Ecosystem (GYE). Host fecal microbiomes facilitate and reflect interactions between the host and its environment. We conducted metagenomic surveys and developed a machinelearning classifier for microbiomes that provided new insights into elk-microbiome biogeography, and the impact of fecal microbiomes on host health and the ecology of elk-wolf (Canis lupus) predation. In the microbiome study, we found strong evidence for multiple management-relevant factors structuring elk microbiomes including body fat percentage, sex, age, and …

Evolution And Diversification Of The Novel Chlorophyll D-Based Photosynthetic Apparatus, Nikea Jonelle Ulrich

Graduate Student Theses, Dissertations, & Professional Papers

The origin of novel traits is an important evolutionary process that generates biological diversity. However, we rarely know the underlying mechanisms of diversification following the innovation of a novel trait. Over two billion years ago, the innovation of chlorophyll (Chl) abased photosynthesis by cyanobacteria sparked the oxygenation of Earth, setting the stage for the emergence of multicellular life. Chl a was subsequently acquired by diverse algae and plants, and in the process, these organisms diversified their light-harvesting systems to absorb a range of visible wavelengths (400-700 nm) (1). Due to the ancient origins of Chl a, however, it is difficult …
