Overgeneral Memory: An Investigation Of The Defensive Exclusion And Functional Avoidance Hypotheses, Mark David Primosch

Graduate Student Theses, Dissertations, & Professional Papers

and PTSD generate overgeneral autobiographical memories. It has been proposed that this phenomenon is the result of functional avoidance—actively avoiding thoughts that would elicit unwanted negative affect. Curiously, the functional avoidance hypothesis of overgeneral memory (OGM) overlaps conceptually with attachment theory’s concept of defensive exclusion. The current study tests whether a model of defensive exclusion predicts the presence of OGM and whether variables underlying the functional avoidance hypothesis (i.e., trauma exposure, PTSD, and depression) account for a significant amount of variance in OGM above and beyond the defensive exclusion model. Threehundred and thirty adults completed an untimed version of the …

“Frozen”: Tonic Immobility And Posttraumatic Outcomes Among Survivors Of Sexual Assault, Nora Grace Halverson

Graduate Student Theses, Dissertations, & Professional Papers

Tonic immobility (TI), a temporary, involuntary state of paralysis marked by motor inhibition and vocal suppression, has been a well-documented occurrence among animals. Humans also experience TI, which has previously been referred to as trauma- or rape-induced paralysis and freezing. TI among survivors of sexual assault has been associated with greater PTSD and increased risk of depression. Existing studies have not adequately explored additional posttraumatic outcomes of TI beyond PTSD diagnostic criteria, nor has prior research sufficiently tested the mechanistic relationship between TI and PTSD. The objective of the current study was to integrate and expand upon prior research regarding …

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 …

Investigating Changes In Er-To-Golgi Protein Transport Following A Short Calcium Pulse: Roles Of Alg-2 And Peflin, Alaa Mohammed Yosri Shaheen

Graduate Student Theses, Dissertations, & Professional Papers

The ER-Golgi interface is a very dynamic environment that involves the movement of protein-loaded vesicles forward and backward. The movement of COPII-coated vesicles from the ER to the Golgi is the initial step in the movement of secreted, organellar, and cell surface proteins toward their final destinations. Many factors can regulate this step, including cytosolic calcium increases. In this study, we examined the effect of a transient calcium pulse on recruitment to ER exit sites of cargo proteins for ER export, the calcium-sensitive regulatory proteins apoptosis-linked gene 2 (ALG-2) and peflin, and the COPII outer coat subunits Sec31A and Sec13. …

An Examination Of Transitioning Meso-Institutions And Markets In The Landscape Of American Politics, Devin Thomas Marconi

Graduate Student Theses, Dissertations, & Professional Papers

This paper bridges the gap in the literature between sociological accounts of market actors provided by Mark Granovetter and Douglas North, meso-institutional examinations of polarization provided by Paul Pierson and Eric Schickler, and the psychological exploration into cross-cutting identities provided by Liliana Mason. I argue that the nationalization and concentration of markets, identities, and politics have led to a transition within the meso-institution of the market from maintaining self-regulating punishment mechanisms to replacing them with self-reinforcing mechanisms, exacerbating affective polarization. Previous works explore the transition within the meso-institutions of the media, interest groups, and political parties. I include the market …

Leveraging Hydrogen Bond Enhanced Halogen Bonding For Higher-Order Anion Helix Formation In Foldamers, Eric Arno John

Graduate Student Theses, Dissertations, & Professional Papers

The ubiquity of folding in biopolymers to induce critical functions like information storage, signal transduction, catalysis, and selective binding has inspired chemists to create synthetic analogs called “foldamers” as materials which emulate and complement the remarkable complexity observed in nature. The ingenuity of chemists has yielded unique methodologies to induce secondary structure (folding) for diverse applications in materials science, medicine, and nanotechnology.

Anion foldamers are a specific class of foldamers engineered to recognize and specifically bind anions through noncovalent interactions. Using anions to induce folding has unique challenges. Anions have diverse topologies, pH dependence, and high free energies of solvation …

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 …

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 …

Navigating The Soviet Experiment: Travels And Writings Of John Dos Passos And Edmund Wilson In Soviet Russia, 1928-1935, Robert Allan Winslow

Graduate Student Theses, Dissertations, & Professional Papers

The travel accounts of Soviet Russia by John Dos Passos (1896-1970) and Edmund Wilson (1895-1972) vividly demonstrate how Western writer-travelers were drawn into Soviet cultural experiments. Only rarely was this process one of literary influence. This thesis focuses on published travel writings by Dos Passos (In All Countries, 1934) and Wilson (Travels In Two Democracies, 1936), as well as journals, letters, and essays, in terms of Soviet cultural developments both writers noted as historically significant in shaping Western views of the Soviet state, and of the methods involved in building socialism and Communism.

The prevalence of virtual museums has grown in recent years and this relatively new exhibition format has presented the museum field with opportunities for growth. In an effort to explore the virtual sphere as an effective avenue for museum growth and change, I conduct an analysis of what virtual museums are, the challenges they pose, and the benefits they can provide to museum education. Case studies of University of California Chico, University of New Mexico, University of Arizona, and University of Nevada Reno’s virtual exhibition of materials from each university’s anthropology collections serves to further the exploration of the efficacy …

The Birds And The Trees: Quantifying The Drivers Of Whitebark Pine Decline And Clark's Nutcracker Habitat Use In Glacier National Park, Vladimir Kovalenko

Graduate Student Theses, Dissertations, & Professional Papers

Whitebark pine (Pinus albicaulis), recently listed as threatened under the Endangered Species Act, is in steep decline in Glacier National Park, Montana, USA due to the non-native pathogen Cronartium ribicola, causal agent of the fatal disease white pine blister rust. A sample of the park’s population suggests that approximately 70 percent of whitebark pines have died, while 65 percent of the remaining trees are infected. Using landscape and climate variables, we show how geographic location, elevation, aspect, solar radiation, relative humidity, and snowpack interact with tree diameter to affect mortality, disease incidence, cone production, and regeneration. We also examine how …

Critical thinking (CT) has become a main focus in the higher education and is viewed as one of the essential skills for students to succeed in the 21^st century. Many studies focus on Chinese students and their CT skills. There is a scarcity of research targeting teachers’ CT. However, teachers are the key to successful education and they play a crucial role in any education reform. Teachers’ perception, attitude, and experience impact the educational practice. Therefore, it is imperative to examine teachers’ CT.

This study utilized a non-experimental causal-comparative methodology with an explanatory mixed methods research design. The purpose …

Uncovering The Connection Between Mental Health Service Availability And Violent Crime: A Test Of Macrolevel Theory, Tatianna R. Pugmire

Graduate Student Theses, Dissertations, & Professional Papers

Since the decline of mental health service funding and availability, the relationship between untreated (or improperly treated) serious mental illness and violent crime is increasingly critical to examine. Rooted in a social support and institutional anomie theory (IAT) perspective, the purpose of this quantitative study is to analyze the relationship between mental health service availability and violent crime rates across the United States for the year 2016. It was hypothesized that findings would suggest an inverse relationship between mental health service availability and rates of violent crime. Results revealed the opposite, however, indicating that the more psychiatric hospitals in an …

Irrigation In The Western United States: Occurrence, Impacts, And Sustainability, David Granger Ketchum

Graduate Student Theses, Dissertations, & Professional Papers

Irrigation represents our greatest intervention in the hydrological cycle, accounting for over 80% of extracted freshwater in the Western U.S. Despite its economic and ecological importance, irrigation’s spatial and temporal occurrence, magnitude, impacts on streamflow, and response during water shortages has not been characterized in our region. The major objective of this dissertation was to systematically assess irrigation over the Western US to answer the following questions: 1) Where and when does irrigation occur within the study region? 2) How has the intensity, area, and distribution of irrigation changed over the course of the past 35 years? 3) What impact …

Faulty Foundations: An Investigation Into Toxic Homes In The Blackfeet Nation, Kathleen Elyse Shannon

Graduate Student Theses, Dissertations, & Professional Papers

In 2002, a class action lawsuit came out of the Blackfeet Nation. The plaintiffs were residents of a federally-funded housing project called Glacier Homes, and they were suing Blackfeet Housing and the Department of Housing and Urban Development because their homes were making them sick. The case got some local media coverage for a couple years. But it was ultimately forgotten and the plaintiffs never got a remedy.

This long-form audio project revives this story and asks listeners to think about these plaintiffs’ arguments in a modern light. The Glacier Homes offer a lens through which to think about several …

Responses Of Elk To Mangement Actions And Hunter Access In The Northern Sapphire Mountains, Montana, Usa, Peter O. Mumford

Graduate Student Theses, Dissertations, & Professional Papers

Chapter 1

Regulation of rifle hunting of adult female elk is the main tool wildlife managers use to manage the abundance of elk (Cervus canadensis) in the western United States. However, elk are increasingly located in areas where hunting access is restricted during rifle-hunting season, decreasing the ability of managers to reduce elk abundance through hunter harvest. Management actions that restricted hunter access in a 26 km2 area and closed 62 kms of predominantly 2-wheel motorized routes occurred in the northern Sapphire Mountains, Montana, USA. We collected data on elk locations before and two years after the management actions and …

Carbon Leakage: Evidence From French Trade Data, Jared Gibbs

Graduate Student Theses, Dissertations, & Professional Papers

Pollution leakage has existed as a concern of both trade theory and domestic policy since questions of the environmental impact of economic activity entered the literature. With the growing threat of climate change and the proliferation of carbon pricing policies around the world, the value of robust estimate of the extent of carbon leakage is particularly acute. Using a pseudo poisson maximum-likelihood (PPML) estimator, I examine French trade volumes to identify potential evidence of carbon leakage. To that end, the net carbon tax between France and its trading partners is regressed on the trade volume in 318 carbon intensive goods. …

The Effect Of Place Attachment And Leisure Identity On Stewardship Participation In The Rattlesnake National Recreation Area And Wilderness, Elena Rene Thomas

Graduate Student Theses, Dissertations, & Professional Papers

As outdoor recreation participation increases in the U.S., and many communities in the American West are experiencing rising amenity migration, park and protected area managers face significant challenges to balance both providing for visitors’ desired experiences and protecting the natural resources on which these experiences depend. Confronted with declining management capacity, agencies are increasingly looking to engage both newer and established recreationists in stewardship behaviors to help maintain these areas and improve human-environment relationships. One barrier to community involvement in stewardship efforts is the need to better understand the connection between recreationists’ antecedent conditions and their motivations to steward. Past …

Building Bridges: Supervisors’ Management Of Competency Questioning, Arianna Camille Vokos

Graduate Student Theses, Dissertations, & Professional Papers

Clinical supervision is an opportunity for supervisors to influence and shape the education of counselors-in-training. Exchanging feedback between supervisees and supervisors can be a challenging aspect of supervision and can have profound impact on the efficacy of supervision, the safety of clients, and the supervision relationship. Understanding the experience and process that supervisors go through when their competence is questioned could be critical to understanding the supervision relationship. Successful management of competency questioning contributes to the efficacy of the supervision relationship, better protection of clients, and positive development of supervisees. Using grounded theory methodology (Charmaz, 2014), this qualitative study addresses …

A Biophysical Approach To Modeling Elevational Range Shifts In Colorado Mammal Communities, Ryan T. Mahar

Graduate Student Theses, Dissertations, & Professional Papers

Species geographic ranges are shifting in the face of contemporary climate warming, and documenting range shifts is crucial to our understanding of the underlying drivers mediating movement in geographic range limits. Studies on elevational range shifts with climate change are beginning to accrue within the literature, though observed shifts are idiosyncratic and difficult to predict. Some species may respond to warming temperatures by shifting their range limits upslope, where temperatures are cooler owing to the adiabatic lapse rate. However, species may also respond to warming temperatures in an elevation-dependent manner: if changes in snow depth expose overwintering organisms to colder …

Life After Ice: Ecology Of Mountain Lakes Across Glacial And Elevation Gradients, Joseph William Vanderwall

Graduate Student Theses, Dissertations, & Professional Papers

Conceptual models of primary succession in lakes often do not match with empirical data. New lakes arising in mountain regions due to the loss of alpine glaciers offer an opportunity to study newly forming lakes. In addition to the loss of alpine glaciers, mountain lakes are currently experiencing rapid changes, including increased vegetation cover, variable snowpack, and increased nutrient deposition. In this dissertation, I used glacial and elevation gradients to investigate the ecology and biogeochemistry of early lakes and how they may change through time. The first chapter details the glacial gradient and shows that early lakes dominated by glacial …

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

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 …

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 …

Equitable Pharmacogenetic Testing Implementation For Rural And Underserved Populations, Shayna Killam

Graduate Student Theses, Dissertations, & Professional Papers

Pharmacogenetic testing has potential to transform healthcare, yet implementation strategies have been limited to major academic medical centers serving metropolitan communities and large health systems. In contrast, rural, community-based health systems are slow to implement these advances, threatening to exacerbate existing healthcare disparities for rural populations. A majority of Montanans live in rural areas, with unique challenges in providing access to pharmacogenetics.

We have established partnerships with three clinical sites who serve rural, underserved populations including American Indian, pediatric, and low socioeconomic status patients. We conducted a needs assessment for pharmacogenetic testing implementation by interviewing 48 key stakeholders. Interview questions …

The Introduction Of Veteran Service Organizations To The State Of Montana’S Department Of Corrections, Zachary C. Rehm

Graduate Student Theses, Dissertations, & Professional Papers

Veteran Service Organizations (VSO) exist throughout the United States and serve veterans, service members, dependents, and survivors. Some VSOs provide programming for veterans in their communities, such as job fairs, organizing fundraising events, raising awareness around the issues affecting veterans, assisting in the application process, and assisting in rehabilitation efforts. The American Legion specifically was chartered by Congress in 1919 as a 'patriotic veterans organization'. Since its conception, the Legion stands at nearly 2 million in membership, scattered throughout 13,000 posts worldwide. Most recent studies from the Justice of Bureau Statistics indicate that 8% of all incarcerated inmates are United …

A Novel Pathway For The Production Of Poly-N-Acetylglucosamine By Borreliaceae, Adam Matthew Drobish

Graduate Student Theses, Dissertations, & Professional Papers

Poly-N-acetylglucosamine (PNAG) is an extracellular polysaccharide consisting of β-1,6 N-acetylglucosamine monomers. PNAG is a key component of biofilms produced by diverse bacteria including Escherichia coli, Staphylococcus aureus, Yersinia pestis, Bacillus subtilis¸and many more. The structure of PNAG is highly conserved across the microbial world. Here, we demonstrate that PNAG is produced by two Borrelia species, Borrelia (Borreliella) burgdorferi and Borrelia hermsii. PNAG production in B. burgdorferi, the Lyme disease spirochete, depends on pngA (bb0620), a gene annotated to express a glycosyl hydrolase family 3 (GH3) enzyme, which is a novel pathway. Surprisingly, in B. burgdorferi, PNAG appears to be intracellular, …
