Subjective Quality Of Life In Dialysis Patients, Cindy Schaumberg
Graduate Student Theses, Dissertations, & Professional Papers
With the ever increasing ability of medical technology to prolong life, quality of life is an increasingly legitimate medical outcome. This is an ethnographic study on the perceived quality of life of hemodialysis dependent end stage renal disease patients. The study used participant observations and in-depth patient interviews to elicit the perspective of hemodialysis dependent end stage renal disease patients. Findings addressed the utility of dialysis for patients of, patient values leading to renal replacement therapy, and issues that might make patients perceive treatment as futile.
The Importance Of Water-Based Ecosystem Services Derived From The Shoshone National Forest, Christopher Aden Armatas
The Importance Of Water-Based Ecosystem Services Derived From The Shoshone National Forest, Christopher Aden Armatas
Graduate Student Theses, Dissertations, & Professional Papers
There is a wide range of goods and services being provided to humans by water resources (e.g. hydropower and recreation), but there is also a diversity of stakeholders that require or desire these benefits, also known as water-based ecosystem services, for everyday life. Land managers working for the United States Department of Agriculture Forest Service in the semi-arid Rocky Mountain Region are tasked with the difficult job of managing scarce water resources in the face of competing human pressures and natural forces (e.g. climate change). Water management decisions on public lands can potentially impact the availability of a wide range …

The roles of sintering and annealing and their …
What Predicts Terrestrial Invertebrate Subsidy Use By Brook Trout (Salvelinus Fontinalis) In Headwater Streams?, Matthew Kestrel Wilson
What Predicts Terrestrial Invertebrate Subsidy Use By Brook Trout (Salvelinus Fontinalis) In Headwater Streams?, Matthew Kestrel Wilson
Graduate Student Theses, Dissertations, & Professional Papers
Spatial subsidies provide critical resources for organisms in receiving habitats, particularly when production in those habitats is low. While it is clear that terrestrial invertebrates provide a critical subsidy for trout, including eastern brook trout (Salvelinus fontinalis), we have limited understanding of what causes input and use of these subsidies to vary among streams. Among the watershed characteristics that may influence input and use of terrestrial invertebrates, I predicted that forest succession stage would be especially important due to differences in terrestrial invertebrate biomass in early and late successional habitats. To test this prediction, I measured terrestrial invertebrate biomass, input …
Wilderness, A Spiritual Antidote To The Everyday: A Phenomenology Of Spiritual Experiences In The Boundary Waters Canoe Area Wilderness, Ian Foster
Graduate Student Theses, Dissertations, & Professional Papers
The purpose of this study was to explore, describe, and explain the phenomena of spiritual experiences in wilderness. The motivations for the research included: growing interest in empirical studies on the relationship between spirituality and human health, increasing concern over human’s loss of spiritual relationships with nature, and personal curiosity about the wild and spiritual nature of wilderness experiences. Research was focused on overnight visitors traveling by canoe in the Boundary Waters Canoe Area Wilderness of northeastern Minnesota. Data from thirty-two semi-structured interviews was used to question, update, and improve understanding of the phenomena. Phenomenological interviews (interviews that situate comments …
Regulation Or Litigation: Using The American Legal System To Address Climate Change, Stacy Lynne Boman
Regulation Or Litigation: Using The American Legal System To Address Climate Change, Stacy Lynne Boman
Graduate Student Theses, Dissertations, & Professional Papers
While a growing scientific consensus recognizes that anthropogenic greenhouse gas emissions are contributing to the global phenomenon known as climate change, little progress has been made to pass comprehensive legislation addressing climate change. Many concerned with the effects of climate change have turned to the American court system as a means of addressing climate change or reducing greenhouse gases. Similar to the early litigation history of many environmental cases, climate change litigation has thus far been unsuccessful in holding major greenhouse gas emitters liable for the impacts of climate change. Plaintiffs have not given up, however. Many climate change cases …
It Took Me Years To Get Those Souvenirs/ Fragments Of A Fiction, Sarahjess Hurt
It Took Me Years To Get Those Souvenirs/ Fragments Of A Fiction, Sarahjess Hurt
Graduate Student Theses, Dissertations, & Professional Papers
Hurt, Sarahjess, M.F.A., Summer 2012 Fine Arts Fragments of a Fiction Thesis Chair: Trey Hill Fragments of a Fiction is an examination of the differences between memory and experience. Through an exploration of both cultural and cognitive shifts I examine how societies, and more specifically, consumers, choose to remember some incidences and forget others. What tools do human beings use to promote some memories and deny others? This inquiry led me to question my own habits of memory, as well as those of others who have shared their stories. In my process, I try to understand the interplay between fact …
Consequences Of Aryl Hydrocarbon Receptor Activation In Crohn's Disease, Jenna Marie Benson
Consequences Of Aryl Hydrocarbon Receptor Activation In Crohn's Disease, Jenna Marie Benson
Graduate Student Theses, Dissertations, & Professional Papers
Activation of the aryl hydrocarbon (AhR), a ligand-activated transcription factor present in many immune cells, can trigger immunosuppressive responses through the generation of regulatory cells. Several AhR ligands exist in the diet including environmental contaminants, such as its prototypical ligand 2,3,7,8-tetrachlorodibenzo-pdioxin (TCDD), and natural sources, such as indole-3-carbinol (I3C) and indirubin. Crohn's disease, a chronic inflammatory state of the gastrointestinal tract, affects millions worldwide; however, the exact cause is unknown and treatments do not cure the disease. The role of the AhR in mucosal immune responses is not well understood to date so we aimed to understand the consequences of …
Genetic Structure And Disease Prevalence Of Boreal Toads (Bufo Boreas) In Glacier National Park, Brett Rebekah Addis
Genetic Structure And Disease Prevalence Of Boreal Toads (Bufo Boreas) In Glacier National Park, Brett Rebekah Addis
Graduate Student Theses, Dissertations, & Professional Papers
Amphibians are more threatened than any other vertebrate group, with 41% of species experiencing declines. The causes of most declines are not well understood, though many declines have been linked to the emerging infectious disease chytridiomycosis. Additionally, amphibians are physiologically constrained to moist habitats and considered poor dispersers; thus, they may suffer genetic consequences of population isolation. To address threats to the persistence of boreal toads (Bufo boreas) in Glacier National Park, USA, I genotyped 551 individuals at 11 microsatellite loci and used spatially independent (STRUCTURE) and spatially explicit (GENELAND) Bayesian methods to describe population genetic structure and identify barriers …

Mapping A Historic Bitterroot Valley, Montana Landscape Using General Land Office Surveyors' Field Notes, Karen M. Shelly
Graduate Student Theses, Dissertations, & Professional Papers
The late 1800s Bitterroot Valley, Montana, landscape and settlement patterns were summarized and mapped using the General Land Office (GLO) surveyors' field notes. Surveyors' observations of six townships from Hamilton to the Stevensville vicinity were examined in several ways. A total of 3321 points of ecological and geographic information and 422 miles of vegetation were mapped from the field notes. Surveyor information, vegetation composition, tree abundance, vegetation spatial structure and distribution of vegetation types were characterized in a multi-part historic vegetation data assemblage of point, line and polygon feature classes. Aquatic, topographic and cultural aspects of the area contributed to …
Mountain Pine Beetle Outbreaks In High Elevation Whitebark Pine Forests: The Effects Of Tree Host Species And Blister Rust Infection Severity On Beetle Productivity, Edith Mary Dooley
Mountain Pine Beetle Outbreaks In High Elevation Whitebark Pine Forests: The Effects Of Tree Host Species And Blister Rust Infection Severity On Beetle Productivity, Edith Mary Dooley
Graduate Student Theses, Dissertations, & Professional Papers
In recent years, the mountain pine beetle (MPB, Dendroctonus ponderosae) has caused dramatic levels of mortality of whitebark pine (Pinus albicaulis). This keystone and foundation tree species is also being killed by the exotic fungus, Cronartium ribicola, which causes the disease white pine blister rust (WPBR). This study examines MPB productivity in whitebark pine compared to that in lodgepole pine, and also in whitebark pine of varying WPBR infection severities to determine if either of these host factors contributes to the current, dramatic MPB outbreaks in whitebark pine. To evaluate host tree effects on MPB, I tracked attack densities, emergence …
Northern River Otter Population Assessment And Connectivity In Western Montana, Darin Edward Newton
Northern River Otter Population Assessment And Connectivity In Western Montana, Darin Edward Newton
Graduate Student Theses, Dissertations, & Professional Papers
Northern river otters (Lontra canadensis) are elusive and difficult to monitor, and little is known about their movement patterns or how populations are structured on the landscape. Otters are sensitive to degradation of aquatic systems, mostly due to loss of prey. This is evident in the Upper Clark Fork River (UCFR), Montana, which has been polluted from decades of mining activity. My objectives for this project were to determine otter population substructuring and connectivity in western Montana and Idaho, and produce a habitat assessment and population estimate for otters in the UCFR. I used genotypic data from otter tissue samples …
Phonological Awareness Skill Of Segmenting In Bilingual English/Spanish Speaking 4- And 5-Year-Old Children, Kate Lorraine Mckay
Phonological Awareness Skill Of Segmenting In Bilingual English/Spanish Speaking 4- And 5-Year-Old Children, Kate Lorraine Mckay
Graduate Student Theses, Dissertations, & Professional Papers
Abstract Segmenting, the ability to pull apart words into their smaller linguistic units, is a known predictor of early literacy. This study investigated the segmenting skills (a component of phonological awareness PA), in bilingual English/Spanish-speaking 4-and 5-year-old children at the levels of syllable, onset-rime and phoneme. The results of this study were then compared to a previous study that explored PA skill development in monolingual English speaking children of the same ages. The comparative analysis explores how bilingualism impacts PA skill development. This study examined the segmenting skills of 31 bilingual students who attended a Spanish immersion school, the majority …

These characteristics -- coupled with overuse and habitat loss -- have resulted in …
Conserving Montana's Sagebrush Highway: Long Distance Migration In Sage-Grouse, Rebecca Elizabeth Smith
Conserving Montana's Sagebrush Highway: Long Distance Migration In Sage-Grouse, Rebecca Elizabeth Smith
Graduate Student Theses, Dissertations, & Professional Papers
Landscape conservation is the mechanism for conserving migratory wildlife in sagebrush ecosystems. We study further a greater sage-grouse (Centrocercus urophasianus; hereafter ‘sage-grouse’) population with the longest-known annual migration, a 240-km journey between summer range in north central Montana, USA, and Saskatchewan, Canada, to winter range north of the Missouri River. We learned more about grouse migration by asking: Do birds fly quickly through a corridor, or do they use stopover habitats within a larger migratory pathway? New GPS-tracking technology revealed that migrating grouse frequent stopover habitats along multiple routes that coalesce to form an integrated pathway. A month-long fall migration …
Tracking Release Of Reservoir Sediment Contaminated By Heavy Metal Mining Waste: A Study Of Large-Scale Dam Removal At Milltown, Montana, Katrina Louise Garcia
Tracking Release Of Reservoir Sediment Contaminated By Heavy Metal Mining Waste: A Study Of Large-Scale Dam Removal At Milltown, Montana, Katrina Louise Garcia
Graduate Student Theses, Dissertations, & Professional Papers
The removal of Milltown Dam at the confluence of the Clark Fork and Blackfoot rivers, near Missoula, Montana, caused an elevation in heavy metals concentration in downstream sediment. The primary source of contamination came from base metal extraction mining waste which had collected in reservoir sediments for more than a century. Health and environmental concerns associated with high concentrations of arsenic and copper in the sediment and nearby groundwater prompted the removal of the dam and its toxic sediments. Milltown Dam was breached on March 28, 2008. Fine-grain (<63 µm) bed sediment was collected between May 3 and August 21, 2008, over a 254-km stretch in the Clark Fork River downstream of the dam and analyzed for concentrations of heavy metals (As, Cd, Cr, Cu, Pb, Zn and Hg). The highest metals concentration occurred in early May, before the peak in stream discharge began transporting massive amounts of sediment. Metals concentration peaked at 290 ppm As, 8 ppm Cd, 2200 ppm Cu, 180 ppm Pb, 2400 ppm Zn, and 2 ppm Hg. Dam removal did not affect Cr, but the other metals were enriched well above background conditions: As was 42x higher and Cu was 103x higher in the lower CFR than its tributaries. Elevated metals concentration extended over the entire study area, decreasing exponentially with distance downstream and returning to near pre-breach conditions by the end of the study period. Supplemental data from the USGS for suspended-sediment was combined with bed sediment results to track the source, sequence and transport mechanisms of sediment release. Contaminants in the sediment acted as tracers, showing that heavily contaminated, fine-grain sediment was translated downstream immediately after dam removal, then nearly two months later the bulk of the sediment was rapidly dispersed during maximum stream discharge and diluted by uncontaminated bank sediment.
Communication Apprehension And Perceived Responsiveness, Elise Alexandra Fanney
Communication Apprehension And Perceived Responsiveness, Elise Alexandra Fanney
Graduate Student Theses, Dissertations, & Professional Papers
The purpose of this study was to construct a training program designed specifically for college students struggling with Communication Apprehension in the public speaking context. Research has consistently found that perceived responsiveness acts as one form of social support, and social support has been found to decrease stress (Maisel, Gable, & Strachman, 2008). Given the fact that anxiety is stressful, the purpose of the study was to explore the relationship between perceived responsiveness of an audience and CA. Using data from an earlier pilot study measuring for correlation between CA and perceived responsiveness in one‟s close relational partner, and using …
A Human Behavioral Ecological Assessment Of The Yellowstone Lake Basin, Yellowstone National Park, Wyoming, Jordan C. Mcintyre
A Human Behavioral Ecological Assessment Of The Yellowstone Lake Basin, Yellowstone National Park, Wyoming, Jordan C. Mcintyre
Graduate Student Theses, Dissertations, & Professional Papers
The Yellowstone Lake Basin has been an important region for hunter-gatherers since the close of the Late Pleistocene that has provided an abundance and well diverse suite of subsistence resources ( i.e prey animals and edible plants). Due the diversity found within this ecosystem, the primary objective of this thesis is to demonstrate that through the tenants of human behavioral ecology, it can be argued that the subsistence and settlement strategies of mobile foragers were heavily influenced by the abundance and availability of subsistence resources. This is based on the premise that resource patches comprising of riparian and grassland habitats …

Rethinking Drought: Planning For Water Scarcity And Climate Variability In The Clark Fork Basin Of Montana, Molly Smith
Rethinking Drought: Planning For Water Scarcity And Climate Variability In The Clark Fork Basin Of Montana, Molly Smith
Graduate Student Theses, Dissertations, & Professional Papers
The purpose of this thesis is to capture experiences of past drought and concerns for future drought conditions in the Clark Fork River Basin of western Montana. These findings could be used to inform drought planning in the Clark Fork River Basin and to guide basin-wide drought planning in the American West. This thesis challenges the assumption of using drought to frame the issue of water deficiency. Deficiencies in precipitation, as a product of natural climate variability, have always existed and will always exist. Water scarcity, on the other hand, is when climate variability and human factors contribute to the …
Theater As A Medium Of Healing: A Critical Analysis Of Copper Thunderbird By Marie Clements, Anna Dulba-Barnett
Theater As A Medium Of Healing: A Critical Analysis Of Copper Thunderbird By Marie Clements, Anna Dulba-Barnett
Graduate Student Theses, Dissertations, & Professional Papers
The idea of the healing power of theater reaches back to Aristotle and his concept of catharsis. Greek philosopher states that tragedy “with incidents arousing pity and fear, wherewith to accomplish its katharsis of such emotions.” The process of catharsis is interpreted as purification or purging of the audience members’ strong emotions as a response to the dramatic action taking place on stage. Today very few western theater practitioners mention that particular aspect of theater in their artistic manifestoes. Yet in Native American theater narratives of illness and healing are ever present. The need for change, and faith in the …
Vitamin D And Athletic Performance: A Critical Assessment For Coaches And Athletes, Lauren Mcguigan
Vitamin D And Athletic Performance: A Critical Assessment For Coaches And Athletes, Lauren Mcguigan
Graduate Student Theses, Dissertations, & Professional Papers
In addition to the well-established role of vitamin D in bone health, there is evidence to suggest that vitamin D may also be associated with the prevention of a wide array of non-skeletal, autoimmune, and chronic diseases. In addition, correlational studies suggest that maintaining a sufficient vitamin D status may positively influence athletic performance indicators, namely strength, power, speed, cardiorespiratory fitness, reaction time, coordination, and body composition. However, there is a lack of consensus among the Institute of Medicine and various vitamin D researchers in defining ideal vitamin D concentrations for both health and performance related benefits. Although this controversy …
Ph Modulation Of Fibril Dissociation And Copper Binding Properties Of The Prion Protein, Xu Qi
Ph Modulation Of Fibril Dissociation And Copper Binding Properties Of The Prion Protein, Xu Qi
Graduate Student Theses, Dissertations, & Professional Papers
The cellular form of prion protein (PrPC) is a cell-surface glycoprotein attached to lipid rafts via its glycosylphosphatidylinositol anchor. Conversion of PrPC to its "scrapie" conformer (PrPSc, the fibrillar form) constitutes the key event of the etiology of prion diseases. Fibril dissociation is necessary for efficient conversion and continued propagation of the disease state. Recent studies have revealed that conversion occurs along the endocytic pathway. To better understand the dissociation process, we have investigated the effect of low pH on the stability of recombinant prion fibrils. We show that under conditions that mimic the endocytic …
Another Day, Another Donut: Political Economy, Agency, And Food In A Montanan Homeless Shelter, Jacqueline Devereaux Semmens
Another Day, Another Donut: Political Economy, Agency, And Food In A Montanan Homeless Shelter, Jacqueline Devereaux Semmens
Graduate Student Theses, Dissertations, & Professional Papers
Despite widespread undernutrition among the homeless, there has been little anthropological research on the experience of food insecurity in this population. Between 20 and 40 percent of the homeless population is undernourished and one third regularly miss meals (Gelberg 1995). This thesis addresses the significant problem of food insecurity in the homeless from a political economic perspective, analyzing how larger social structures influence the individual person. Fifteen residents at a shelter in Missoula, MT were interviewed about their dietary practices and experience of social service programs. The macro-social level influences the diet of the individual in two important ways: first, …
Bison Conservation In The Northern Great Plains, Michel Thomas Kohl
Bison Conservation In The Northern Great Plains, Michel Thomas Kohl
Graduate Student Theses, Dissertations, & Professional Papers
Temperate grasslands are the least protected ecosystem in the world. In North America, only < 4% of tallgrass prairie, 64% of mixed-grass prairie, and 66% of shortgrass prairie are intact. Historically, grazing played an important role in maintaining prairie landscapes through nutrient cycling and the diversification of vegetation structure and composition. Within grasslands, the plains bison (Bos bison) was the most numerous and influential grazer. However, by 1900 bison were reduced to ¡Ü 1,000 animals throughout North America. Today, bison are scattered throughout their historical range, numbering > 500,000 individuals. Recent questions have surfaced regarding the success of this effort, however, because < 21,000 plains bison are managed as conservation herds (n = 62) and 8% of those herds are managed on areas of > 2,000 km2. In addition, >100,000,000 cattle now graze rangelands in the U.S. and Canada leading to questions regarding the ecological significance of replacing bison with livestock. Our objectives were to increase knowledge regarding the ecological similarities between bison and cattle, and to determine how both species can be managed to mimic ecological patterns that approximate historical bison populations. We used behavioral observations, movement analyses, and Resource Selection Function (RSF) analyses too quantify …

Characterization Of A Cardboard Recycling Facility's Plastic Waste For Beneficial Use, Tova Sardot
Graduate Student Theses, Dissertations, & Professional Papers
An issue with old cardboard container (OCC) recycling is the generation of a plastic waste that currently either gets land-filled or burned. A Wandel screen, a common process unit, generates 35% of overall rejects that contain 75% of the facility's total plastic output. Plastic-rich Wandel wastes have not been well characterized. This study evaluated the plastic waste stream for engineering new, second-life products. Wandel wastes were composed typically of hot melt adhesives (37%), polypropylene (32%), polyethylene (17%), and polystyrene (9%). Proportions varied 10% or less in each polymer category. The plastic waste was compounded, milled and injection molded into test …

Coming To The Surface: The Environment, Health, And Culture In Butte, Montana, Stacie Lynn Barry
Graduate Student Theses, Dissertations, & Professional Papers
Butte is a small town in southwest Montana that was profoundly shaped by over a century of mining and smelting activities. Today, Butte is a post-industrial city that is the focal point of America's largest Superfund site as well as the nation's largest National Historic District. There are two types of remediation occurring in Butte: environmental and cultural. Environmental remediation occurs throughout the city, most notably at the operable units of the Butte Superfund sites. This remediation does not restore the environment to its original state but instead reclaims it to a level of risk deemed acceptable by the EPA. …
Composition, Distribution, And Conservation Of The Herpetofauna Of Santa Barbara Mountain, Honduras, Alicia Marie Ward
Composition, Distribution, And Conservation Of The Herpetofauna Of Santa Barbara Mountain, Honduras, Alicia Marie Ward
Graduate Student Theses, Dissertations, & Professional Papers
Santa Barbara Mountain is an important and unique ecosystem in Honduras because of its topography and high proportion of endemic species. Despite its prospects for valuable discoveries and the profusion of threats to its biodiversity, there is almost no scientific information about Santa Barbara Mountain. This study is the first systematic investigation of hepetofauna species on the mountain. Research objectives included inventorying of the reptile and amphibian species present on Santa Barbara Mountain, identifying locations and microhabitat types where each species can be found, and determining if the amphibian disease chytridiomycosis is present and in which locations. A community education …
Consequences Of Aryl Hydrocarbon Receptor Activation In Steady-State And Inflammatory Dendritic Cells, Thomas Simones
Consequences Of Aryl Hydrocarbon Receptor Activation In Steady-State And Inflammatory Dendritic Cells, Thomas Simones
Graduate Student Theses, Dissertations, & Professional Papers
The aryl hydrocarbon receptor (AhR) is a steroid-like transcription factor that mediates the toxicity of various environmental pollutants, including 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and TCDD-like compounds. Exposure to environmentally relevant levels of TCDD and TCDD congeners has been shown to cause immune suppression, yet the mechanisms underlying TCDD-induced immune suppression remain poorly understood. Dendritic cells (DCs) are professional antigen presenting cells (APCs) that play an integral role in both innate and adaptive immune responses. DCs constitutively express AhR and represent a highly sensitive immune cell population to AhR activation by environmental pollutants. In a murine inflammatory bone marrow-derived DC (BMDC) model, AhR …
Forgotten Sepulchers: The Uninscribed Tombs In The Valley Of The Kings In Luxor, Egypt, Roselyn Campbell
Forgotten Sepulchers: The Uninscribed Tombs In The Valley Of The Kings In Luxor, Egypt, Roselyn Campbell
Graduate Student Theses, Dissertations, & Professional Papers
The elaborately decorated tombs in the Valley of the Kings in Luxor, Egypt, have captured the imagination of scholars and tourists alike for thousands of years. Yet despite the attention lavished on these tombs, they are outnumbered in the Valley of the Kings uninscribed tombs that have been largely ignored. Excavations in several of the uninscribed tombs have demonstrated that although their walls may be bare, the tombs are certainly not empty, and a variety of finds ranging from scattered funerary objects and human remains to several nearly intact burials of high officials have been uncovered. This thesis will assemble …
