The purpose of this paper is to provide assistance in developing a program to control the release of dental mercury amalgam in Missoula, Montana. To do this, three research components were carried out. The first consisted of a survey to determine whether Missoula dentists are following the American Dental Association’s (ADA) recommended Best Management Practices (BMPs) for mercury amalgam waste. The second component involved interviewing local dentists in an effort to include their voice in the process, as well as to determine what may motivate them to comply with a dental mercury control program. The final component of research involved …
Predicting Northern Goshawk Dynamics Using An Individual-Based Spatial Model, Melanie A. Smith
Predicting Northern Goshawk Dynamics Using An Individual-Based Spatial Model, Melanie A. Smith
Graduate Student Theses, Dissertations, & Professional Papers
The northern goshawk (Accipiter gentilis) is a US Forest Service Region 2 Sensitive Species, requiring the Black Hills National Forest to manage for its viability. Previous studies have suggested that a model integrating goshawk population demographics, habitat availability, and territoriality would have the ability to predict population dynamics including goshawk locations, population size, and population viability. An individual-based spatial model was created for the Black Hills goshawk population. This project focused on evaluating our current understanding of goshawk dynamics, and making individual- and population-level predictions as appropriate following model validation. The model simulated demographics and behavior of individuals and usage …
The Role Of The Macrophage In Asbestos Induced Autoantibody Production, David J. Blake
The Role Of The Macrophage In Asbestos Induced Autoantibody Production, David J. Blake
Graduate Student Theses, Dissertations, & Professional Papers
Environmental exposure to silicate compounds such as silica and asbestos has been associated with increased autoimmune responses and the development of autoimmune disease in humans. Residents of Libby, MT have experienced significant asbestos exposure due to an asbestos contaminated vermiculite mine near the community over several decades. Residents have developed numerous asbestos-related diseases as well as increased autoimmune responses. However, the exact mechanism by which Libby amphibole asbestos generates autoimmune responses is unclear. To elucidate a possible mechanism for asbestos induced autoimmunity, the cellular effects of Libby amphibole asbestos were characterized in vitro using a phagocytic murine macrophage cell line, …

Development Of The Rocky Mountain Foreland Basin: Combined Structural, Mineralogical, And Geochemical Analysis Of Basin Evolution, Rocky Mountain Thrust Front, Northwest Montana, Emily Geraghty Ward
Graduate Student Theses, Dissertations, & Professional Papers
The sub-Middle Jurassic unconformity exhumed at Swift Reservoir, in the Rocky Mountain thrust belt of Montana, exposes structures that call for a re-evaluation of the deformation history at this locale. The unconformity separates Late Mississippian Madison Group carbonate (~340 Ma) from the transgressive basal sandstone of the Middle Jurassic (Bajocian-Bathonian) Sawtooth Formation (~170 Ma). Fieldwork established that northwest-trending, karst-widened fractures (grikes) are filled with cherty, phosphatic sandstone and conglomerate of the Sawtooth Formation and penetrate the Madison Group for 4 meters below the unconformity. Clam borings, filled with Sawtooth sandstone, pierce the unconformity surface, some of the fracture walls, and …
First-Year Growth And Survival Of Habitat Revegetation Trials On The Lower Colorado River, Mexico, Stephen Dwight Handler
First-Year Growth And Survival Of Habitat Revegetation Trials On The Lower Colorado River, Mexico, Stephen Dwight Handler
Graduate Student Theses, Dissertations, & Professional Papers
Sweeping changes across the Colorado River watershed in the 20th century resulted in near-complete collapse of the natural communities in the Colorado River Delta (CRD) in Mexico. A brief return of freshwater flows in the 1980s and 1990s showed the riparian corridor remains resilient to past damage, and the CRD remains a vital area for habitat conservation and restoration. This project aimed to test conclusions drawn from similar projects in the United States and show that revegetation projects are possible along the lower Colorado River in Mexico. From November 2006 to October 2007, we tested the effects of various treatments …
The Structure Function Relationship Of Silica Polyamine Composites, Mark Anthony Hughes
The Structure Function Relationship Of Silica Polyamine Composites, Mark Anthony Hughes
Graduate Student Theses, Dissertations, & Professional Papers
The goals of this thesis were to improve the performance of silica polyamine composites by manipulating the surface structure and to understand the relationship between, polymer structure and ligand modification of the grafted polyamine. Improvements in silica polyamine composite performance resulted from modifying silica gel with methyltrichlorosilane (MTCS) substituted for a molar fraction of reagent chloropropyltrichlorosilane (CPTCS), which has been traditionally employed. MTCS does not possess a terminal chloride group thus preventing the subsequent attachment of a polyamine to this moiety. MTCS has a smaller molecular volume than CPTCS and as a consequence greater coverage of the silica gel surface …
Ecological Process And The Blister Rust Epidemic: Cone Production, Cone Predation, And Seed Dispersal In Whitebark Pine (Pinus Albicaulis), Shawn Thomas Mckinney
Ecological Process And The Blister Rust Epidemic: Cone Production, Cone Predation, And Seed Dispersal In Whitebark Pine (Pinus Albicaulis), Shawn Thomas Mckinney
Graduate Student Theses, Dissertations, & Professional Papers
Whitebark pine (Pinus albicaulis), a high elevation foundation species, is experiencing population declines throughout the northern part of its range. The introduced fungal pathogen, Cronartium ribicola (white pine blister rust), infects whitebark pine and kills cone-bearing branches and trees. Blister rust has spread nearly rangewide and damage and mortality are highest in the northwest US and southwest Canada. Mortality caused by mountain pine beetle (Dendroctonus ponderosae) population upsurges, and successional replacement and loss of regeneration opportunities from fire suppression, are also impacting some whitebark pine populations. Within this dissertation, I present three manuscripts that address the impact of whitebark pine's …
The Diaspora Of Korean Children: A Cross-Cultural Study Of The Educational Crisis In Contemporary South Korea, Young-Ee Cho
The Diaspora Of Korean Children: A Cross-Cultural Study Of The Educational Crisis In Contemporary South Korea, Young-Ee Cho
Graduate Student Theses, Dissertations, & Professional Papers
The diaspora of Korean children first started after the Korean War in the 1950s. Abandoned by their impoverished mothers and shunned by society, many orphan children were sent abroad for adoption, which was the best, if not the only, available solution at the time. Half a century later, South Korea today is no longer a desperately poor country, and yet an increasing number of young children are still being sent abroad. The exodus of children, termed as the diaspora of Korean children in this study, is an out-of-country solution chosen by both students and parents in response to an educational …
Hormonal Mediation Of A Unique Behavioral Polymorphism In The White-Throated Sparrow (Zonotrichia Albicollis), Meredith Bettencourt Swett
Hormonal Mediation Of A Unique Behavioral Polymorphism In The White-Throated Sparrow (Zonotrichia Albicollis), Meredith Bettencourt Swett
Graduate Student Theses, Dissertations, & Professional Papers
In this body of work, I examine how testosterone (T) physiology mediates the life-history trade-off between mating effort and parental care in the White-throated Sparrow. This species exhibits a behavioral polymorphism that occurs in both sexes. White-striped (WS) morphs are more territorially aggressive, sing more frequently and seek more extra-pair copulations. Tan-striped (TS) morphs provision nestlings more frequently. Thus this species roughly illustrates the trade-off between mating effort and parental care. I examine T physiology on three levels: plasma titres, binding globulins and response to the social environment. I ask whether levels of T correlate with morph-specific behavior and does …
Lithologic And Hydrogeologic Controls On The Occurrence, Transport, And Fate Of Mtbe In Fine Grained Glacial-Lacustrine Sediments, Mary Kathryn Sutherland
Lithologic And Hydrogeologic Controls On The Occurrence, Transport, And Fate Of Mtbe In Fine Grained Glacial-Lacustrine Sediments, Mary Kathryn Sutherland
Graduate Student Theses, Dissertations, & Professional Papers
In April of 1994, a leaking 60,480L gasoline underground storage tank was removed from George’s Conoco in Ronan, Montana. Investigations discovered a free product plume extending under Highway 93, with dissolved phase contamination (including MTBE) extending 460 m west to Spring Creek. Though geochemical sampling has established the general plume extent, the influence of aquifer heterogeneities on plume position and transport behavior is poorly described. The purpose of this work is to characterize the physical controls on plume migration. In addition to standard well installation and geochemical sampling, geotechnical tools including cone penetration testing (CPT) and Membrane Interface Probe (MIP), …
Hunters In The Garden: Yup’Ik Subsistence And The Agricultural Myths Of Eden, Benjamin Kuntz
Hunters In The Garden: Yup’Ik Subsistence And The Agricultural Myths Of Eden, Benjamin Kuntz
Graduate Student Theses, Dissertations, & Professional Papers
Yup’ik writers and Yup’ik subsistence offer valuable challenges, parallels, and alternative models to mainstream nature writing’s discourse surrounding human relationships to the land, a discourse that carries an inherent agricultural bias. An introduction to western Alaska’s Nunivak Island provides context for Chapter 1, which demonstrates the fluidity of cultural, geographical, and historical margins through discussion of the works of Yup’ik journalist John Active and historian and ethnographer James Clifford. Chapter 2 provides an overview of Yup’ik subsistence centered around the community of Bethel, Alaska, then subjects mainstream nature writing, represented mostly by Wendell Berry, to critiques supplied by Canadian anthropologist …
Blm Land Use Planning In Western Oregon: A Case Study For Integrating Public Participation In Natural Resources Planning, Emily Ruth West
Blm Land Use Planning In Western Oregon: A Case Study For Integrating Public Participation In Natural Resources Planning, Emily Ruth West
Graduate Student Theses, Dissertations, & Professional Papers
Public participation can fundamentally improve natural resources planning and decision-making. On an ad hoc basis, it has been shown that public participation improves the durability and sustainability of plans and decisions; it increases the technical, consensus-building, and decision-making capacity of the public; it increases levels of trust; and it improves relationships between agency personnel and members of the public. Despite the proliferation of these new tools and strategies and their successful implementation, innovative and inclusive public participation methods have still not become widely integrated into the natural resources planning and administrative decision-making processes of federal agencies. Utilizing the Bureau of …
Building A Better Local Food System: A Case Study Of The Western Montana Growers Cooperative, Beth Anne Neely
Building A Better Local Food System: A Case Study Of The Western Montana Growers Cooperative, Beth Anne Neely
Graduate Student Theses, Dissertations, & Professional Papers
Local food systems aiming to re-create direct links between producers and consumers are emerging in the United States and elsewhere in response to the social, economic, and environmental consequences of the globalizing food market. Despite growing consumer demand for locally produced food, small-scale producers may not have the capacity to meet the needs of wholesale food purchasers, such as restaurants, grocery stores, schools, or hospitals, thus limiting their markets to direct sales to consumers. Wholesale customers, in turn, face a number of barriers to purchasing local food. Producer cooperatives may alleviate some of the challenges faced by wholesale buyers while …

Changing Attitudes: Congressional Rhetoric, Race, And Education Inequalities, Jennifer Kathleen Richert
Graduate Student Theses, Dissertations, & Professional Papers
Richert, Jennifer Kathleen, M.A., May 2007 IYFD Changing Attitudes: Congressional Rhetoric, Race, and Education Inequalities Chairperson: Otto Koester Through an analysis of Congressional rhetoric regarding public school in the context of racial equality, three terms emerge as reoccurring concepts that drive discussions on contemporary educational conversations: narrowing the gap, disadvantaged students, and accountability. I have designed this study to determine whether the way politicians in U.S. Congress use these terms have racial undertones that ultimately work to maintain a culture of minority oppression. This study opens with an introduction describing my personal interest, followed with an extensive literature review regarding …
Characterization Of Long Pathlength Capillary Waveguides For Evanescent Fluorescence Applications, Eric Paprocki
Characterization Of Long Pathlength Capillary Waveguides For Evanescent Fluorescence Applications, Eric Paprocki
Graduate Student Theses, Dissertations, & Professional Papers
The optical properties of a novel fused silica fiber-optic capillary waveguide (FOCap) for fluorescence spectroscopy were evaluated. Evanescent fluorescence from samples in the FOCap was measured by coupling the FOCap to a light source and a fluorescence spectrophotometer. The FOCap has negligible excitation light loss over long lengths (20 m or more) for a range of wavelengths. The evanescent fluorescence was linear up to at least 20 m for a solution in the core and up to at least 15 m for a fluorophore covalently attached to the inner surface. Evanescent fluorescence measurements in 50, 150, and 250 µm inner …
Monitoring Program And Assessment Of Coyote Predation For Olympic Marmots, Julia Judyta Witczuk
Monitoring Program And Assessment Of Coyote Predation For Olympic Marmots, Julia Judyta Witczuk
Graduate Student Theses, Dissertations, & Professional Papers
Witczuk, Julia J. M.S., Summer2007 Wildlife Biology MONITORING PROGRAM AND ASSESSMENT OF COYOTE PREDATION FOR OLYMPIC MARMOTS Chairperson: L. Scott Mills The Olympic marmot (Marmota olympus) is an endemic species to the Olympic Peninsula, Washington State. Although nearly all of its range is enclosed within Olympic National Park, declines and local extirpations of the species have been documented. The most plausible driver of the decline appears to be an increase in predator pressure. My thesis had two main objectives. First, I investigated the role of non-native coyotes (Canis latrans) in causing marmot mortality. Through park-wide carnivore scat analysis I determined …
Moving Boxes Closer To Home: The Role Of Sysco Corporation In Food System Localization, David Scott Kennedy
Moving Boxes Closer To Home: The Role Of Sysco Corporation In Food System Localization, David Scott Kennedy
Graduate Student Theses, Dissertations, & Professional Papers
Increasing demand for local food by foodservice establishments creates new opportunities and challenges for the local food movement. While there is considerable potential for local suppliers to sell more product volume closer to home, the business needs of foodservice establishments may not be compatible with direct marketing approaches that have fueled the growth of the movement. Foodservice establishments typically rely on distributors to provide them with the majority of their food. Drawing on the success of direct marketing, new indirect marketing approaches that link producers and consumers through intermediaries are increasingly advanced within food system localization. The dominance of SYSCO …
Organizing Rural Communities For Effective Citizen Science Programs, Anna Dean Holden
Organizing Rural Communities For Effective Citizen Science Programs, Anna Dean Holden
Graduate Student Theses, Dissertations, & Professional Papers
Citizen science, or the use of volunteers for scientific projects, is becoming a popular way for agencies and organizations to collect data. The benefits of citizen science include saving the agency or organization resources, educating the community about conservation issues, and promoting land stewardship. Currently, many citizen monitoring organizations are based in urban areas, whereas their projects are located near more rural towns. Research shows that demographics such as area of residence can be a factor in the public’s attitude toward any scientific or land management project (Williams et al, 2002; Kellert, 1978, 1985; Vaske et al, 2001). This fact …
Energy Flow In A Floodplain Aquifer Ecosystem, Brian Reid
Energy Flow In A Floodplain Aquifer Ecosystem, Brian Reid
Graduate Student Theses, Dissertations, & Professional Papers
We developed an energy budget to identify energy sources for the invertebrate community of a large 20 km2 floodplain aquifer, based on biomass distributions, organismal respirometry, in situ community respiration, mesocosm and microcosm experiments, stable isotopes and invertebrate gut contents. The invertebrate respiration scaling exponent was 0.474 (+/- 0.068, 95% CI) across six orders in body mass, which is significantly lower than the ¾ power scaling predicted by metabolic theory. Invertebrate production was dominated by copepods (Diacyclops, Acanthocyclops, Bryocamptus), Stygobromus amphipods, and amphibiont stoneflies, and ranged from 26.9 to 4200 mg C/m3 sediment/year. Production and density showed a U-shaped response …
Lobachevski Illuminated: Content, Methods, And Context Of The Theory Of Parallels, Seth Braver
Lobachevski Illuminated: Content, Methods, And Context Of The Theory Of Parallels, Seth Braver
Graduate Student Theses, Dissertations, & Professional Papers
In the 1820's, Nikolai Ivanovich Lobachevski discovered and began to explore the world's first non-Euclidean geometry. This crucial development in the history of mathematics was not recognized as such in his own lifetime. When his work finally found a sympathetic audience in the late 19th century, it was reinterpreted in the light of various intermediate developments (particularly Riemann's conception of geometry), which were foreign to Lobachevski's own way of thinking about the subject.
Because our modern understanding of his work derives from these reinterpretations, many of Lobachevski's most striking ideas have been forgotten. To recover them, I have produced an …
Managing Multiple Identities: A Qualitative Study Of Nurses And Implications For Work-Family Balance, Claire Marie Spanier
Managing Multiple Identities: A Qualitative Study Of Nurses And Implications For Work-Family Balance, Claire Marie Spanier
Graduate Student Theses, Dissertations, & Professional Papers
The ways in which people manage organizational, professional, and familial identities can have significant implications for work-family balance. This is particularly true for nurses, who have a strong sense of professional identity and may be likely to experience work-family tensions. By framing work-family tensions as related to identity, we can see the ways in which being a “good” employee, a “good” nurse, and a “good” family member are both complementary and contradictory. This study highlights ways in which being “good” employee facilitates and hinders an individual’s ability to be a “good” nurse. Furthermore, it demonstrates how being a “good” nurse …

A Lithic Raw Materials Study Of The Bridge River Site, British Columbia, Canada, Darrell Albert Austin
Graduate Student Theses, Dissertations, & Professional Papers
New excavations at the Bridge River Site were conducted over two seasons (2003, 2004), collecting over 16,000 artifacts, of which about 4,000 were from dated contexts. These dated materials were used for a materials study to look at settlement patterns, trade and prestige. The Bridge River Site is located in an area of complex geology that contains many unique and valuable resources for the prehistoric and the present. The accreted terranes are a series of land extensions created by buoyant rocks (island arcs) carried by the subduction zone and accreted or added to the main continent. These accreted terranes collided …
A Modern Examination Of Marcus Goldstein’S Mexican Immigrant Population Data: Comparisons Of Mexican-Born And U.S.-Born Children And Adults Living In 1930’S America And Mexico, Amanda Katelin Gango
A Modern Examination Of Marcus Goldstein’S Mexican Immigrant Population Data: Comparisons Of Mexican-Born And U.S.-Born Children And Adults Living In 1930’S America And Mexico, Amanda Katelin Gango
Graduate Student Theses, Dissertations, & Professional Papers
Modern statistical methods were employed in order to test the statistical validity and conclusions of Marcus Goldstein’s (1943) original data consisting of nineteen different anthropometric measurements on two different groups of individuals, Mexican immigrants and their children residing in the San Antonio, Texas area and Mexican natives living in central and northern Mexico. Using independent samples T-tests, an analysis of covariance, and an RMET analysis, significant differences among variables compared between Mexican natives and Mexican immigrants and their U.S. born children were identified and interpreted. Variation was attributed to geographical location and length of time spent in the United States. …

Democratic Administration In The United States Forest Service, Nancy Leigh Leifer
Graduate Student Theses, Dissertations, & Professional Papers
Pluralism, the dominant theory in citizen involvement in the United States Forest Service since the 1950s, has prolonged the process of determining the public interest by promoting the use of appeals and lawsuits. The advent of more collaborative public involvement strategies in the past fifteen years offers the opportunity to assess whether participatory democracy offers a better paradigm for determining the public interest. This research focused on four cases of reported successful collaboration in Region One of the Forest Service and involved in-person interviews with 17 Forest Service officials and 24 citizen and interest group leaders. The researcher translated pluralist …

Development Of Fecal Dna Sampling Methods To Assess Genetic Population Structure Of Greater Yellowstone Bison, Florence Marie Gardipee
Development Of Fecal Dna Sampling Methods To Assess Genetic Population Structure Of Greater Yellowstone Bison, Florence Marie Gardipee
Graduate Student Theses, Dissertations, & Professional Papers
The bison (Bison bison) of Yellowstone National Park (YNP) and Grand Teton National Park (GTNP) represent two of only three remaining populations of plains bison that have no evidence of hybridization with cattle. Therefore, these bison are an important source for ecological and genetic restoration of wild bison. Little is known regarding genetic population structure and gene flow among the Greater Yellowstone Area (GYA) bison herds. I evaluated the feasibility of fecal DNA sampling for genetic analyses of wild bison populations. I used matched blood and fecal samples from eight radio-collared bison from Hayden Valley breeding group (YNP), and multiplex …

Achieving Environmental Justice For The Community Of Opportunity, Montana: An Assessment Of Superfund Concerns, Kathleen A. Hasenbank
Achieving Environmental Justice For The Community Of Opportunity, Montana: An Assessment Of Superfund Concerns, Kathleen A. Hasenbank
Graduate Student Theses, Dissertations, & Professional Papers
EXECUTIVE SUMMARY The community of Opportunity, Montana, is surrounded by an area many consider to be the largest Superfund site in the United States. The nearby Opportunity Ponds is a major consolidation area for mining-related contaminated wastes in the state of Montana, and Opportunity residents have voiced concerns about their well water, windblown dust, and other issues since at least the late 1990s. Furthermore, the community has been subjected to ongoing environmental injustices: they feel they have been left to bear an unfair environmental burden without compensation and feel left out of important decision-making processes that affect them. I have …
Assessment Of Whitebark Pine Seedling Survival For Rocky Mountain Plantings, Deborah Kay Izlar
Assessment Of Whitebark Pine Seedling Survival For Rocky Mountain Plantings, Deborah Kay Izlar
Graduate Student Theses, Dissertations, & Professional Papers
Whitebark pine (WBP) is a keystone species of Rocky Mountain alpine and subalpine areas. A pervasive non-native fungal disease (white pine blister rust), mountain pine beetle infestation, and successional replacement by shade-tolerant competitors following decades of fire exclusion have severely reduced whitebark pine and threaten these high-elevation ecosystems. Land managers are attempting to reverse whitebark pine’s decline by increasing regeneration of rust-resistant trees while restoring successional processes. Restoration efforts include the planting of whitebark pine seedlings and over 200,000 seedlings have been planted on National Forest, BLM and National Park service lands. In this Rocky Mountain (RM) study, select whitebark …
