Now, Tribes on Fort Peck, Northern Cheyenne and Fort Belknap are partnering with conservation organizations to help repair the prairie ecosystem. Driven by cultural knowledge and a sense of responsibility, many Tribes are learning from past mistakes and nearby successes. …

Emission And Chemistry Of Volatile Organic Compounds In Western U.S. Wildifre Smoke, Wade Jeremy Permar

Graduate Student Theses, Dissertations, & Professional Papers

Wildfires are a significant source of volatile organic compounds (VOCs) in the western U.S., emitting hundreds to thousands of different species that play key roles in tropospheric oxidation, ozone production, and secondary organic aerosol formation. Many of these VOCs have only recently been identified and quantified in laboratory burning experiments. Consequently, little is known about their emissions from wildfires, which species are most important for plume OH oxidation chemistry, and how they evolve as smoke plumes age. This dissertation aims to improve our understanding of the emissions and chemistry of VOCs in wildfire smoke using detailed in situ measurements made …

Bacteriophage Infection Induces Intracellular Polyamine Accumulation As A Defense Mechanism In Pseudomonas Aeruginosa, Camilia Dornelles De Mattos

Graduate Student Theses, Dissertations, & Professional Papers

Cells are constantly monitoring their extracellular environment for danger signals that warn of imminent threats. When cells are killed by physical or other non-infectious injuries, they release concentrated intracellular molecules into the surrounding area. These danger-associated molecules alert other cells that danger is nearby. When cells are killed by pathogens, they release both damage-associated and pathogen-associated signals. Both eukaryotic and bacterial cells sense these molecules and make threat assessments of cellular injury. Here, I show that lysis of Pseudomonas aeruginosa and other bacterial species releases high concentrations of polyamines that are in turn taken up by surviving cells in a …

Mitigating The Damaging Effects Of Covid-19 Isolation In The Elderly, Hailey Powell, Addie Slanger, Mazana Boerboom, Brenna Spurling, Maria Goheen

Undergraduate Theses, Professional Papers, and Capstone Artifacts

In an effort to both analyze how COVID-19 has impacted traditionally isolated communities and prevent loneliness, we have created a pen-pal program between UM students and senior adults. We have implemented a pilot pen-pal program to create lasting social bonds without exposing seniors to COVID-19. The program is currently running through the Davidson Honors College “Intro to Honors” course, with plans to leave the program self-sustaining in future semesters. To pair partners, we distributed interest surveys and matched relevant interests. To inform people of how loneliness affects seniors, we created a brochure that highlights our research, with plans to distribute …

The Relationship Between Food Retailers And Distributors, Madison Seigler, Julia Anderson, Aidan Morton, Cassandra Williams, Victoria Bloomgren, Jacob Tutty

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Our understanding of the science of anthropogenic climate change and its immediate and indirect impacts has grown within the last decade.Alongside anincrease in concern for the inequities within the industrialized food system, climate change is impacting agriculture and the communities that depend on it in myriad ways. These challenges have catalyzed investment in sustainable agriculture, “eat local” food movements, and rethinking of all aspects of food systems, including consumers, producers, retailers, and distributors. The body of literature on food systems primarily focuses on the connection between consumers and retailers; however, there is a notable absence of literature on the relationships …

Understanding And Improving Barriers To Treatment And Care Of Postpartum Depression, Marcy N. Hanson

Graduate Student Theses, Dissertations, & Professional Papers

Background: Postpartum depression (PPD) is a multifaceted and complex issue that impacts not only the mother, but also the infant and social system and may influence how healthcare is accessed. Compounding the effects of PPD are comorbidities such as perinatal substance use. Utilization of substances during pregnancy can increase feelings of anxiety and depression, result in cognitive and physiological consequences for the infant and impair relationships with healthcare providers.

Purpose: The studies completed for this dissertation revealed current concerns regarding PPD within the context of screening practices, perinatal substance use and rural practice implications.

Methods: Three studies were conducted. Study …

Arctic Greening: Characterizing Tundra Vegetation From In-Situ And Remotely Sensed Observations, Shira Ann Ellenson

Graduate Student Theses, Dissertations, & Professional Papers

As the Arctic has warmed at twice the rate of the global average, vegetation productivity has also been increasing. While satellite remote sensing is useful for summarizing Arctic-wide trends, changes in tundra species heights, densities, composition, and distribution can be missed at coarse resolution. Smaller, plot-scale studies are necessary to better understand vegetation dynamics at fine scales occurring on the ground.

In 1995, high-resolution traditional aerial photographs and in-situ measurements of vegetation characteristics were taken at a series of plots established on the Alaskan North Slope. Repeat field surveys in 2021 revealed increases in plant cover for deciduous shrubs and …

Getting To Know You: Relationship Formation Across Development In Octodon Degus, Amber Lynn Thatcher

Graduate Student Theses, Dissertations, & Professional Papers

Social relationships are a necessary part of group formation and cohesion across many animal species and can increase the health and fitness of the individuals involved. These benefits are seen across the lifespan, although the exact advantages and functions differ across developmental stages. Our current understanding of how relationships are formed and maintained is incomplete. Previous findings suggest that a measure of stability may be a useful method for understanding how relationships are formed and how this process may differ across development. The goal of this dissertation is to investigate the variability of social interactions over time and how it …

The purpose of the current investigation is to determine how to better document ongoing cognitive-communication deficits and to characterize the nature of how these deficits impact daily life and communicative participation, using a multidimensional assessment protocol.

Method: A multiple case study design was selected to comprehensively document the cognitive-linguistic functioning of multiple individuals with concussion. Five participants completed one session over a telehealth platform that included four …

Mark My Words: The Linguistic Complexity Of The Journal Of Personality And Social Psychology Abstracts And Subsequent Citations, Alivia Lauren Zubrod

Graduate Student Theses, Dissertations, & Professional Papers

Through language, scientific communication can positively impact the progression and advancement of science. Given the value of scientific communication, it is important to explore what factors might be associated with influential scientific communication. Surprisingly, relatively little research has examined the linguistic properties of influential scientific communication. In effort to overcome this gap in the literature, I used integrative complexity, a well-validated linguistic variable, to assess the relation between article abstracts and subsequent number of citations from one of the most highly-cited social psychology journals (Journal of Personality and Social Psychology). In an analysis of over 1.4 million words from 9,884 …

Mansfield, Marines, And Mothers: The Politics Of Resistance To The American Intervention In North China From 1945-1946, James Robert Compton

Graduate Student Theses, Dissertations, & Professional Papers

At the conclusion of World War II, American citizens, including millions of deployed servicemen, reasserted the democratic freedoms they sacrificed to win the war. The American intervention in North China during the Chinese Civil War presented a ripe opportunity for civic restoration in late 1945. Controversial and seemingly at odds with the stated goals of the Second World War—namely the “Four Freedoms” and the Atlantic Charter—the US military presence in North China faced formidable domestic political obstacles. This thesis explores the nexus of domestic politics and foreign policy in the post-World War II era. Focusing on 1945-1946, this project steps …

ABSTRACT

The Request Is Not Compatible: Competing Frames of Public Lands Discourse in the Lolo Peak Ski Resort Controversy

Co-Chair (in absentia): Steve Schwarze Co-Chair: Joel Iverson

In mid-2003, the United States Forest Service (USFS) received a pre-application for a Special Use Permit to build and operate an all-season ski resort on public lands near Missoula, Montana. The ensuing public deliberation over the possible use of protected lands for outdoor commercial recreational purposes provides a site of rhetorical inquiry. In this rhetorical criticism I analyze and evaluate arguments presented by the USFS, …

Bridging The Gap: Where Indigenous Knowledge And Western Science Come Together To Shape Environmental Stewardship, Bowman Leigh

Graduate Student Theses, Dissertations, & Professional Papers

In the era of climate change, humans are grappling with how to ensure that natural resources exist into the future. For millennia, Indigenous people have actively managed the environment, drawing upon deep connections to the land passed down through generations. The Western worldview, on the other hand, sees humans as separate from nature — an attitude that has led to many of the environmental crises we see today.

This portfolio examines places and programs where Western science and Indigenous knowledge (IK) or traditional ecological knowledge (TEK) come together to shape environmental stewardship. Western science and IK/TEK are inherently different ways …

Distal Sibling Grief: Exploring Emotional Affect And Salience Of Listener Behaviors In Stories Of Sibling Death, Margaret C. Brock

Graduate Student Theses, Dissertations, & Professional Papers

Communicated Narrative Sense-Making (CNSM) theory is used as a theoretical framework to understand the storytelling surrounding a sibling’s death years after the loss. Analysis of 174 narratives from individuals whose siblings died five or more years ago revealed that a neutral tone, rather than the use of positive or negative affect, was predominant in this retrospective storytelling. When affect was present, it was more likely to be negative than positive. However, positive affect was associated with an individual’s satisfaction with life when it was present. The neutrality and frequency of retrospective storytelling among distally bereaved siblings in this study may …

Voices Of The Often Unheard: The Environmental Impacts Of Catastrophic Wildfire Events On Individuals With Developmental Disabilities, Mary Madison Mckenzie

Graduate Student Theses, Dissertations, & Professional Papers

The Thomas Fire for a time was the largest wildfire in California history, burning 281,893 acres and destroying 1,063 structures. Within three years, the August Complex Fire, at 1,032,649 acres, almost quadrupled that record. Climate related disasters such as these have impelled social science researchers to heed calls for a paradigm shift in understanding the risks climate change poses to the social world, in particular, disaster risks for vulnerable groups. Existing research tends to focus on disasters such as hurricanes, featuring risks for vulnerable populations by race, class, and/or individuals with disabilities in general, but not for individuals with developmental …

Catch My Drift? Perceptions And Experiences Of Pesticide Contamination Of Organic Crops In Montana, Sarah Rodgers

Graduate Student Theses, Dissertations, & Professional Papers

Pesticide drift and inadvertent contamination pose particular risks to organic production. Some organic producers have lost their crops, certification, and/or organic markets because of contamination events. Through this thesis research, I explain the perceptions and experiences that certified organic farmers in Montana have about drift and inadvertent pesticide contamination. I conducted semi-structured interviews with eleven certified organic farmers from various regions of Montana. Along with one-on-one interviews with organic farmers, interviews with industry and regulatory officials were conducted to better understand the policies and procedures that control what happens when drift occurs at the state level. Industry and regulatory official …

A Qualitative Examination Of Teacher's Perspectives Of Social-Emotional Learning And Spirituality In The Public School Setting, Amy E. Violante

Graduate Student Theses, Dissertations, & Professional Papers

Spirituality is not often discussed in the field of school psychology or the public school setting. However, it is understood to be a factor supporting resilience and well-being among children. Aspects of spirituality align with the core components of social-emotional learning (SEL), which relate to awareness of self and others, relationship skills, and responsible decision-making. The aims of the current study were to explore public school teachers’ perspectives of spirituality and SEL in the classroom, of the relationship between these topics, and of supporting spiritual and SEL development in order to promote student well-being. Semi-structured interviews were conducted with twelve …

A Reynolds Number Based Sampling Technique For 3-D Vector Fields In Computational Fluid Dynamic Environments, Trent James Schweitzer

Graduate Student Theses, Dissertations, & Professional Papers

Effective visualization of unsteady, time-dependent vector fields in a virtual environment is not a trivial task. This is due to the fact that most visualization techniques require the user to have a prior understanding of how the vector field will behave to set the parameters used to create the visualization. In this thesis we will take air flow data from a computational fluid dynamic simulations to calculate the amount of turbulence (represented as Reynolds numbers) to identify regions of interest. We then calculate wind pathlines that will intersect with these points sampled from these regions. We address the issue of …

Graduate Student Theses, Dissertations, & Professional Papers

Objectives: This is a validation study of Biddle (2019), where much of the same materials are used, with the addition of new data from other databases to include more Native American and minority samples. A comparison database will also be analyzed against this data, with known cases of live individuals assaulted and assessed by health officials, some in IPV situations. All data is analyzed to discover which fracture locations are most common in IPV situations and which ethnic, sex, and age groups are most affected. Most fractures analyzed are those of the maxillofacial area, concentrating on the Zygomaticomaxillary Complex (ZMC) …

Alternative Splicing Regulates The Innate Immune Response To Viral Infection, Luke A. White

Graduate Student Theses, Dissertations, & Professional Papers

Rift Valley fever virus (RVFV) is a mosquito-borne RNA virus that infects humans and livestock in sub-Saharan Africa and the Arabian peninsula, causing disease ranging from a mild flu-like illness to liver damage, blindness, hemorrhagic fever, death, and, especially in livestock animals, high rates of abortive pregnancies. There is no approved vaccine for RVFV, and as a disease with a high rate of spread that causes severe illness, it is listed as a Category A pathogen by the USA CDC. A better understanding of RVFV’s molecular virology will be instrumental to combating RVFV as climate change causes its mosquito host …

Understanding Media Richness And Social Presence: Exploring The Impacts Of Media Channels On Individuals’ Levels Of Loneliness, Well-Being, And Belonging, Ashley M. Arsenault

Graduate Student Theses, Dissertations, & Professional Papers

Loneliness is a universal part of being human and is detrimental to well-being. The need-to-belong hypothesis claims that individuals frequently having positive interactions with people close to them mitigates their loneliness. Media richness theory adds that rich media channels allow individuals to perceive higher levels of social presence and maintain those vital, close relationships. Understanding how a given media channel impacts online interactions and, in turn, the interactants is vital. This study used a pretest-posttest equivalent groups experimental design to examine if individuals who interacted with a close relationship partner over a rich media channel would have a decrease in …

Combined Effects Of Temperature And Heavy Metals On The Performance Of The Giant Salmonfly., James Frakes, Amanda Andreas, Benjamin P. Colman, Aurthur Woods

Graduate Student Theses, Dissertations, & Professional Papers

In many freshwater ecosystems, communities of aquatic insects are facing the combined stresses of warmer waters due to climate change and increased exposure to heavy metal toxicants. Although each stressor may threaten aquatic insects independently, they also likely interact in important ways to affect insect physiology and performance. Here we investigate this potential interaction using two populations of aquatic nymphs of the giant salmonfly, Pteronarcys californica, collected from adjacent rivers in Montana: naïve individuals from Rock Creek, a relatively pristine stream, and individuals from the Upper Clark Fork River, which has a history of heavy metal pollution and higher …

Examining The Interpersonal Psychological Theory Of Suicide In A Sample Of Individuals With Psychosis, Jennifer Villa

Graduate Student Theses, Dissertations, & Professional Papers

Psychotic disorders confer high risk for suicidality. Previous research has found the symptom clusters of psychosis to have differential relationships with risk for suicidal ideation and behavior. Despite evidence for unique determinants of suicide among people with disorders on the psychosis spectrum, little research has examined theoretical models of suicide that aim to explore the transition from suicidal thoughts to behavior in this population. The Interpersonal-Psychological Theory of Suicide (IPTS) may be particularly useful in delineating this transition, as the constructs underlying the IPTS overlap with symptoms and experiences salient in people with psychosis. We examined baseline data from an …

Are Risk Attitudes And Rainfall Variability Determinants Of Diversification? Evidence From Rondonia, Brazil, Brenna Swinger

Graduate Student Theses, Dissertations, & Professional Papers

Risk exposure and management are inherent to smallholder farmers. One of the risks they face is climate change. Climate change decreases rainfall, increases frequency of drought, adds heat stress to crops from higher temperatures, and leads to higher rainfall variability. The threat of rainfall variability causes higher production in some years and lower in others. Even if the average income remains the same, people’s welfare is reduced by the variability and the size of the loss will depend on their attitudes towards risk.

Diversification is one adaption strategy that may help reduce climate risk. Diversified farmers produce multiple types of …
