Improving Mental Health Care For Transgender Consumers: Providers’ Attitudes, Knowledge, And Resources, Hillary Gleason

Graduate Student Theses, Dissertations, & Professional Papers

Transgender individuals may present for treatment with a variety of mental health needs, both related and peripheral to their gender identity and expression. Compounding stigma and other life stressors elevate mental health risks in transgender communities, and the barriers to mental health services are manifold. As such, the current research study was designed to determine the competency of mental health care providers to address the unique needs of transgender consumers. Online surveys gauged mental health providers’ knowledge of transgender issues, implicit and explicit transphobic attitudes, as well as treatment decisions with transgender and cisgender consumers; moreover, workplace resources and infrastructure …

The Design And Synthesis Of Small Molecule Drugs To Inhibit Epigenetic Alterations Caused By Dna Methyltransferase 1, Patrick Anthony Barney

Graduate Student Theses, Dissertations, & Professional Papers

The acquisition of genomic alterations is a defining feature of human cancers. Many cancer chemotherapies rely upon an apoptotic pathway to eradicate cells containing those alterations. One such alteration is the epigenetic methylation of cytosine in DNA, which occurs at CpG sites in dense clusters of CpG dinucleotide repeats within the gene promoter region. The maintenance of appropriate methylation levels of DNA is necessary during normal DNA replication. Disruption of correct and appropriate methylation patterns leads to DNA associated with transcriptional silencing. Cytosine methylation is catalyzed by DNA methyltransferase enzymes (DNMTs), which transfer a methyl group from S-adenosylmethionine to the …

Efficacy Of Three Backward Masking Signals, Robert David Sears

Graduate Student Theses, Dissertations, & Professional Papers

Increased backward masking has been correlated with Auditory Processing Disorders (APD). An efficacious test of the backward masking function that is compatible with naïve listeners could have clinical utility in diagnosing APDs. In order to determine an appropriate probe for such a test, three 20-ms signal-types were compared for ease-of-task. Response times (RT) were taken as a proxy for ease-of-task. Seven participants used a method-of-adjustment to track threshold in the presence of a 50-ms broadband-Gausian-noise backward-masker. The signal-types yielded two comparisons: Linear rise-fall on a 1000Hz sine-wave versus a “chirp” (750 Hz-4000Hz); Linear rise-fall vs Blackman gating function on a …

Hyperconnected School Leadership: Shared Experiences, Elizabeth Sue Wargo

Graduate Student Theses, Dissertations, & Professional Papers

Leaders remain perpetually connected to their work because of the rapid advancement of information technology. This research, using a qualitative approach, explored how increased connective technology is affecting school leaders with the central question: How is hyperconnectivity experienced by school leaders? Using personal interviews, the lived experiences of fifteen international middle and high school principals with one-to-one student-to-device programs were collected. Raw transcriptions of their experiences were analyzed using the descriptive phenomenological approach as outlined by Giorgi (2009). This approach allowed for the data to be reduced into a single narrative description shared by all participants indicating the essences of …

Methyl-Cpg Binding Proteins Mediate Octopaminergic Regulation Of Complex Behavioral Traits, Tarun Gupta

Graduate Student Theses, Dissertations, & Professional Papers

An organism’s survivability in the natural world is contingent to its ability to respond rapidly and appropriately to various cues and challenges in its physical and social environment. The dynamicity of various environmental and social factors necessitates plasticity in morphological, physiological and behavioral systems – both at the level of an individual organism and that of a species. For more than century, natural selection of existing genetic variation in populations has helped us understand such plasticity across generations. However, recent years have seen a re-emergence of somewhat contentious quasi-Lamarckian framework with which organisms can reliably transmit acquired traits to subsequent …

Advanced Measurements Of Undersampled Globally Significant Biomass Burning Sources, Chelsea Elizabeth Stockwell

Graduate Student Theses, Dissertations, & Professional Papers

During the fourth Fire Lab at Missoula Experiment (FLAME-4) laboratory campaign, we burned historically undersampled and globally significant biomass fuels. The open-path Fourier transform infrared (OP-FTIR) spectroscopy system provided new emissions data while measuring gases that overlap with fire emissions measured in numerous field campaigns. Based on the lab-field comparisons, we conclude that our lab-measured emission factors (EFs) for some of the fires can be adjusted to better represent typical open burning. In addition we deployed a high-resolution proton-transfer-reaction time-of-flight mass spectrometer (PTR-TOF-MS) to characterize biomass burning (BB) emissions for the first time. BB is the second largest global atmospheric …

Political Ecology Of Cordyceps In The Garhwal Himalaya Of Northern India, Laura Bess Caplins

Graduate Student Theses, Dissertations, & Professional Papers

In the Garhwal, Indian Himalaya, rural mountain people labor to piece together their livelihoods in an ever changing world. One particular group, the Bhotiya (an ethnically and culturally distinct tribal group) were historically engaged in seasonal migration (i.e. transhumance) to take advantage of scarce mountain resources and trade relations with Tibet. This livelihood practice has all but disappeared; however, today one way the Bhotiya are adapting to these changing circumstances is by engaging in the collection and sale of a valuable alpine medicinal fungus locally known as keera jari, and commonly called the caterpillar fungus or cordyceps (Ophiocordyceps sinensis). The …

Landscape To Local: A Multi-Scale Evaluation Of Voluntary Efforts To Reduce Fragmentation And Enhance Management Of Rangelands For Sage-Grouse, Joseph Tyler Smith

Graduate Student Theses, Dissertations, & Professional Papers

For imperiled species, the hierarchical nature of habitat selection suggests the need for a hierarchical approach to conservation: address threats to persistence operating at broad scales on populations before focusing on the quality of patches or availability of particular resources used by individuals. We apply this approach to conservation and management of habitat for greater sage-grouse (Centrocercus urophasianus) in the eastern portion of their range where cropland conversion continues to fragment sagebrush grasslands. Using locations of active leks in portions of Montana, Wyoming, North Dakota, and South Dakota as spatial indices of populations, we found sage-grouse distribution was highly sensitive …

Close Call With Nonexistence: A Memoir, Jeff Gailus

Graduate Student Theses, Dissertations, & Professional Papers

Fred Eduard Gailus was born on April 26, 1944, in Memelland, a place that no longer exists. It was a tiny sliver of Germandom on the far eastern edge of Hitler’s outsized German Reich. When the Soviet Red Army swept through on their way to Berlin, to end World War Two and the reign of terror perpetrated by the German people, the homeland of my father’s ancestors was wiped off the map forever. Thanks to the courage and tenacity of his mother, Fred survived the largest forced migration in human history to marry young and raise a family of four …

Conservation Genetics On The Frontline, Kenneth W. Rand

Graduate Student Theses, Dissertations, & Professional Papers

Conservation genetics stands out as an effective tool for discovering and monitoring rare, endangered or invasive populations of plants and animals. Particularly when compared to traditional search and capture methods, it provides more holistic studies to preserve the disappearing biodiversity of the American West and the world.

Three stories highlight the work done to preserve biodiversity through the use of conservation genetics:

1. Trout Rescue: A new hope for westslope cutthroat in Montana How to save a disappearing westslope cutthroat trout through genetic rescue by adding genetic diversity to ensuring future survival in increasingly warming waters more harm than good. …

Human Shields And Redistribution Of Prey Species Complicate The Utility Of Protected Areas As Ecological Baselines, Wesley Sarmento

Graduate Student Theses, Dissertations, & Professional Papers

A key goal of protected areas is the conservation of biodiversity, an aim that garners increasing public support through positive experiences. Increasing visitation, however, can come at the cost of reduced ecological integrity. A fundamental conundrum is that if parks are to serve as our most pristine places, then we must understand how our presence alters species interactions. Species redistributing closer to people is of growing management concern both in and out of national parks because of 1) human safety, 2) animal health, and 3) ecological consequences. Across parks drivers of distributional change are often dissimilar, and include movement to …

Cyber-Victimization And Delinquency: A General Strain Perspective, Ian D. Greenwood

Graduate Student Theses, Dissertations, & Professional Papers

This study examines juvenile delinquency and cyber-victimization from a general strain perspective. General strain theory provides a model where strain is experienced through the (1) loss of something valued, (2) the presentation of noxious stimuli, or (3) the inability to achieve valued goals. As a coping mechanism for strain, some juveniles react through criminal or delinquent behavior. This thesis predicts that cyber-victimization increases the likelihood of physical fighting, weapon-carrying, and truancy at school. Using the 2013 National Crime Victimization Survey: School Crime Supplement, the hypotheses are analyzed using multivariate logistic regression models that include other known correlates of delinquency. Marginal …

Ecology Of The Alluvial Aquifer Of The Nyack Floodplain On The Middle Fork Of The Flathead River, Montana, Amanda Gay Delvecchia

Graduate Student Theses, Dissertations, & Professional Papers

The pristine Nyack Floodplain on the Middle Fork of the Flathead River in Northwestern Montana contains an expansive alluvial aquifer that is extremely limited in organic carbon, yet supports abundant and diverse hyporheic stoneflies. My dissertation focused broadly on how these large consumers persist in such an oligotrophic system. In particular, I studied the ecological role of methane dynamics.

Confidence Judgments In A Simultaneous Task Using Sprague Dawley Rats (Rattus Norvegicus), Jessica K. Kumm

Graduate Student Theses, Dissertations, & Professional Papers

In the present experiment, metacognitive confidence judgments were measured in the Sprague-dawley rats using a simultaneous discrimination task. Performance on two types of trials were compared: Forced and Choice. For Forced trials, subjects were required to classify a range of eight tones as either a “long” or “short” tone with the four longest frequency durations comprising the “long” tone category and the four shortest frequency tones comprising the “short” tone duration category. The Choice trials were identical to the Forced trials with the exception that a bailout response was also available, allowing the subject to advance to the next trial …

A Comparison Of Course Quality Surveiy Results From Students On Gender Balanced And Gender Imbalanced Field Courses At Nols, Alexandra M. Alway

Graduate Student Theses, Dissertations, & Professional Papers

There is an extensive database of literature about diversity in outdoor Environmental Education and any of the studies focus on NOLS specifically. Several studies have investigated the impact of course composition in terms of gender as well as socioeconomic diversity; however, the research studies about course composition and gender were limited to differences between single gender and coed groups. The role of gender ratios on coed groups has not been widely researched. This study was designed to fill this gap in the research literature. Using course quality survey data, results showed that the student responses were significantly different between gender …

Extreme Hybrid Growth, Genomic Imprinting, The Large X Effect, And The Drivers Of Speciation In Mammals, Thomas David Brekke

Graduate Student Theses, Dissertations, & Professional Papers

Mammalian hybrids often show abnormal growth, indicating that developmental inviability may play an important role in mammalian speciation. Yet it is unclear if this recurrent phenotype reflects a common genetic basis. Here I describe patterns of hybrid inviability between two closely related species of dwarf hamsters, Phodopus campbelli and P. sungorus. Using genetic crosses, I found extreme parent-of-origin dependent growth in hybrid embryos and placentas. Abnormal growth in hybrid mammals has been empirically linked to genomic imprinting, the parent-specific silencing of a single allele that occurs in many genes involved in regulating embryonic growth. Epigenetic disruptions of genomic imprinting activate …

Cold Lapse, Tressa Jones

Graduate Student Theses, Dissertations, & Professional Papers

cold lapse addresses the abstract notions of time and loss while conveying the value of observing the present. The postmodern view of time, the grid’s vernacular, and the aesthetics of postminimalism are my foundation for communicating time’s passage and its consequential sensations of absence. The duration of a slow drip, the cycle of breath and the sequential motion of a hand folding paper each mark passing moments. By observing these signs the phenomenon of time may be appreciated. Care and ephemerality in the work require the viewer’s sensitivity when encountering and witnessing it, much like the demands of observing the …

Predicting Climate-Induced Impacts On Seasonal Stream Temperatures In The Crown Of The Continent Ecosystem, Leslie Anne Jones

Graduate Student Theses, Dissertations, & Professional Papers

Changes in seasonal climate patterns are altering thermal distributions of freshwater ecosystems worldwide. The Crown of the Continent Ecosystem is one of the most biologically diverse ecosystems in North America, spanning northwestern Montana, USA, Alberta and British Columbia, Canada. The fluvial landscape consists of pristine freshwater habitats that provide strongholds for many aquatic species. My dissertation work provides the first broad scale analysis of seasonal climate effects on spatiotemporal patterns of stream temperature in the Crown of the Continent, and a multi-scalar analysis of potential impacts to bull trout (Salvelinius confluentus) populations, the most stenothermic cold-water fish in the northern …

Redskins Revisited: Competing Constructions Of The Washington Redskins Mascot, Eean Grimshaw

Graduate Student Theses, Dissertations, & Professional Papers

This project looks at how synecdoche and ideographs function in the construction of competing position in the controversy surrounding the Washington Redskins mascot. I examined the rhetoric produced by both the Washington Redskins organization and its fans, as well as the rhetoric of Change the Mascot, the Oneida Indian Nation of New York and other opponents between the years of 2013 and 2015. Based in part on Moore’s (1993, 1994, 1997) argument that synecdoche and ideographs often prevent resolution and produce irreconcilable conflict, I extend this notion insofar as the controversy surrounding the Redskins mascot appears to be shifted towards …

Attitudes Toward Execution: The Tragic And Grotesque Framing Of Capital Punishment In The News, Katherine Shuy

Graduate Student Theses, Dissertations, & Professional Papers

This essay undertakes a detailed frame analysis of print and electronic media coverage of three nationally publicized death penalty cases between the years of 2014 and 2015. Drawing specifically from the work of Kenneth Burke (1984), this research argues that tragically framed death penalty cases reify victim/perpetrator discourses and cause the actual act of execution to be a fitting resolution within a narrative. Burke’s (1984) grotesque-mystical frame and Bakhtin’s (1984) theory of the grotesque body are used to argue that the media’s portrayal of botched executions help highlight the incongruities with the system of capital punishment, and cause audiences to …

Knife River Flint Distribution And Identification In Montana, Laura Evilsizer

Graduate Student Theses, Dissertations, & Professional Papers

An examination of the spatial, temporal, and functional distribution of Knife River flint in Montana, and a study in misidentification of Knife River flint in archaeological assemblages. Lithic sourcing has the potential to provide a plethora of information to archaeologists: resource procurement strategies, mobility patterns, trade networks, and the preferencing of particular lithic material types. However, without proper identification it is impossible to study the distribution of lithic materials from their source. Knife River flint, a brown chalcedony, is a particularly fascinating material, geologically occurring in a small area, but culturally distributed over a large area. I analyze the distribution …

What Do You Think I Am?: On Perceiving Unintelligibility In The Nonbinary Gender Experience, James Warwood

Graduate Student Theses, Dissertations, & Professional Papers

What does it mean to be “retired from gender,” and what role does such an identity play in daily life? Engaging with the work of Maurice Merleau-Ponty and Judith Butler, this project attempts to elucidate the experience of nonbinary – that is, external to the male/female gender binary – gendered individuals, and the ultimate unintelligibility of that experience. Merleau-Ponty’s phenomenological approach to perception allows for an exploration of the social norms and regulations that determine how gender is defined in Western culture; combined with Butler’s significant work on gender and its performativity, phenomenology proves a useful tool for revealing the …

Toward An Ontology Of Exhaustion: On The Affective Structures Of Masculinity In The American Oilfield, John W. Jepsen

Graduate Student Theses, Dissertations, & Professional Papers

What is the significance of the oil encounter in the lives of men living and working in the modern oilfields of the United States? Engaging with both literary examples of the lives of men in the Interior West and the personal experiences and reflections of the author, this essay seeks to examine the connections between ideology and place as it works to shape the identity and affect of men in America's oilfields, ultimately ending in them identifying with the very resources their activities seek to exploit and exhaust. Utilizing Theodore Adorno's Minima Moralia as its moral touchstone, this essay works …

Exploring Park Support: A Study Of Philanthropy And Other Support For Yellowstone National Park, Geoffrey G. Havens

Graduate Student Theses, Dissertations, & Professional Papers

Support for charitable causes has long been a topic studied in the hopes of uncovering the reasons for donations and other support behaviors. However, holistic examination of support for places, such as parks, has been relatively untouched as an area of research. One such place where understanding such support is important is Yellowstone National Park, the first designated National Park and one of the most visited parks in the United States. A lack in adequate government funding to meet increasingly heavy visitation has led the park to increasingly rely on outside support for the park.

The purpose of this study …

The Western Stemmed Point Tradition: Evolutionary Perspectives On Cultural Change In Projectile Points During The Pleistocene-Holocene Transition, Lindsay D. Scott

Graduate Student Theses, Dissertations, & Professional Papers

In this thesis I analyze the cultural techniques of Paleoindians in North America by examining the diversification and fusion of stemmed projectile point traditions using an evolutionary analysis. The Western Stemmed Point tradition has an extensive regional and temporal distribution throughout the Intermountain West and High Plains during the Paleoindian period. In an effort to determine how stemmed projectile point technologies relate to each other, I applied a phylogenetic approach to construct heritable patterns of projectile point histories. By measuring the physical traits of those points and using a macro-evolutionary theoretical approach, changes in artifact form can be acquired and …
