Multi-Scale Hydrogeomorphic Influences On Bull Trout Spawning Habitat In Snowmelt-Dominated Headwater Streams, Jared Robinson Bean Jan 2012

Multi-Scale Hydrogeomorphic Influences On Bull Trout Spawning Habitat In Snowmelt-Dominated Headwater Streams, Jared Robinson Bean

Graduate Student Theses, Dissertations, & Professional Papers

I investigated relationships between geomorphology, hydrogeology, and bull trout (Salvelinus confluentus) redd occurrence and density at multiple spatial scales in gravel-bed, pool-riffle, snowmelt dominated headwater streams of northwestern Montana. Subreach redd occurrence tended to be associated with the finest available textural facies. In subreach streambed sections hosting bull trout redds, redd density was significantly (at α=0.05) positively related to bankfull Shields stress (τ*bf, p=0.04) and bankfull Shields stress adjusted for grain stress only (τ**bf, p=0.02). In stream reaches hosting bull trout redds, reach-average redd density was significantly positively related to reach-average τ**bf (p=0.02) and reach-average streambed grain size (D16, p=0.01; …


Ecological Causes Of Life History Variation Tested By Meta-Analysis, Comparison, And Experimental Approaches, Daniel Croft Barton Jan 2012

Ecological Causes Of Life History Variation Tested By Meta-Analysis, Comparison, And Experimental Approaches, Daniel Croft Barton

Graduate Student Theses, Dissertations, & Professional Papers

The ecological causes of life history variation among taxa and the arrangement of such variation along geographic gradients is enigmatic despite the proximity of life history traits to fitness and implications for understanding basic and applied population ecology. One classic explanation for the arrangement of avian life histories along a `slow-fast' gradient, where species at low latitudes have `slow' life history traits (low fecundity and mortality) and species at high latitudes have `fast' life history traits (high fecundity and mortality), is the increase in seasonality of resources with increasing latitude (Ashmole's hypothesis). Despite broad acceptance, this hypothesis has been supported …


Language Change In Spanish Heritage Speakers: The Interaction Between Lexical And Grammatical Aspect, Jackelyn Kelly Van Buren Jan 2012

Language Change In Spanish Heritage Speakers: The Interaction Between Lexical And Grammatical Aspect, Jackelyn Kelly Van Buren

Graduate Student Theses, Dissertations, & Professional Papers

This thesis focuses on preterit and imperfect usage in the Spanish of Chilean-American heritage speakers. Spanish heritage speakers in the United States are second generation bilinguals who learn Spanish in the home from Spanish speaking parents and learn English from school and the community (Montrul 2002; Rothman 2007). When societal factors limit heritage language exposure, tense and aspect morphology is susceptible to change (Guijarro-Fuentes & Clibbens 2004). Findings of a study on 11 Chilean-American heritage speakers show that production of the preterit is overextending, resulting in less frequent use of the imperfect. Large-scale studies of US Spanish-English bilinguals’ use of …

Assessing The Role Of Shame And Honor During The Alta Conflict, Michael T. Bremmer Jan 2012

Assessing The Role Of Shame And Honor During The Alta Conflict, Michael T. Bremmer

Graduate Student Theses, Dissertations, & Professional Papers

For nearly a century the Sami peoples of Norway were subject to colonial policies of assimilation and integration. According to historians of the Sami, colonial processes stigmatized Sami individuals and the Sami culture, producing feelings of shame. The concept of shame, for both individuals and groups, centers on experiencing fear, pain, and/or uneasiness, and requires a judging audience. Honor is about individuals transcending self-interest and the need for individuals and groups to acquire self-esteem for that purpose; it also requires a judging audience. Concepts of shame and honor played an important role during the Alta conflict; a watershed moment in …


Anomalous Wave Dispersion In The Cyclohexanedione-Bromate Chemical Oscillator, Ryan Boger Jan 2012

Anomalous Wave Dispersion In The Cyclohexanedione-Bromate Chemical Oscillator, Ryan Boger

Graduate Student Theses, Dissertations, & Professional Papers

A modified six-variable Oregonator model presented here successfully reproduces a significant portion of the behavior observed in the Ferroin-catalyzed cyclohexanedione variant of the Belousov-Zhabotinsky (CHD-BZ) reaction. The phenomena of anomalous velocity dispersion (in which following waves may catch up to, rather than fall behind an initial excitation wave), wave-stacking, and backfiring have been successfully reproduced numerically as resulting from non-monotonic [Br-] decay to the steady state in the wake of an excitation pulse. The non-monotonic decay is seen as a "dip" in [Br-] following the passage of a chemical wave. This dip in [Br-] decay curve allows a following wave …

What They Consider, How They Decide: Best Practices Of Technical Experts In Environmental Decision-Making, Cassandra J. Hemphill Jan 2012

What They Consider, How They Decide: Best Practices Of Technical Experts In Environmental Decision-Making, Cassandra J. Hemphill

Graduate Student Theses, Dissertations, & Professional Papers

Drawing from qualitative data gathered from environmental management professionals, this paper describes best practices for decision-making in environmental clean-up. Technical experts are knowledgeable about both cultural and technical rationality and employ both, as appropriate, to achieve more robust decisions. Experts use active, passive, and interactive communicative strategies to reduce uncertainties and manage tensions. Deliberation is used to achieve robust decisions. The analysis suggests that organizations can improve acceptability of decisions by authorizing experts to incorporate cultural rationality early in the decision process.

A Comparison Of Metadiscourse Markers And Writing Quality In Adolescent Written Narratives, Susan Gold Sanford Jan 2012

A Comparison Of Metadiscourse Markers And Writing Quality In Adolescent Written Narratives, Susan Gold Sanford

Graduate Student Theses, Dissertations, & Professional Papers

Discourse, a series of sentences that communicates a topic, consists of two distinct yet connected components. The first element is the propositional content or the meaning of the sentences, and the second consists of the words and expressions that enhance the communicative efficiency and effectiveness of the factual message. Metadiscourse markers, members of the second linguistic category, guide the reader through the text and establish a means for the writer to interact or influence the reader. The use of metadiscourse in writing and speaking embodies the concept that communication is more than just the exchange of information, facts, and figures. …


Internal Facies Architecture Of A Regressive To Transgressive Wave-Dominated Delta In The Upper Cretaceous Eagle Formation, South-Central Montana, Eleanor Spangler Jan 2012

Internal Facies Architecture Of A Regressive To Transgressive Wave-Dominated Delta In The Upper Cretaceous Eagle Formation, South-Central Montana, Eleanor Spangler

Graduate Student Theses, Dissertations, & Professional Papers

The Santonian-Campanian Eagle Formation in south-central Montana was deposited along the western margin of the Cretaceous Western Interior Seaway and is composed of a series of well preserved regressive and transgressive deposits. This study documents the depositional evolution of the informal lower member of the Eagle Formation exposed near Billings, MT. Detailed mapping and characterization of the internal stratigraphy, facies architecture, and bounding surfaces of the lower Eagle provide the basis for reconstruction of a paleodelta system that serves as a valuable reservoir analog within the Cretaceous Seaway and elsewhere. This study demonstrates that the informal lower member of the …

Functional Encryption As Mediated Obfuscation, Robert Perry Hooker Jan 2012

Functional Encryption As Mediated Obfuscation, Robert Perry Hooker

Graduate Student Theses, Dissertations, & Professional Papers

We introduce a new model for program obfuscation, called mediated obfuscation. A mediated obfuscation is a 3-party protocol for evaluating an obfuscated program that requires minimal interaction and limited trust. The party who originally supplies the obfuscated program need not be online when the client wants to evaluate the program. A semi-trusted third-party mediator allows the client to evaluate the program, while learning nothing about the obfuscated program or the client’s inputs and outputs. Mediated obfuscation would provide the ability for a software vendor to safely outsource the less savory aspects (like accounting of usage statistics, and remaining online to …


Genetic Structure And Disease Prevalence Of Boreal Toads (Bufo Boreas) In Glacier National Park, Brett Rebekah Addis Jan 2012

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 …


Are Perceptions Reality? A Look At Subjective Well-Being In East Timor, Emily Klungtvedt Jan 2012

Are Perceptions Reality? A Look At Subjective Well-Being In East Timor, Emily Klungtvedt

Graduate Student Theses, Dissertations, & Professional Papers

Subjective well-being has been of growing interest over the past several years for multiple reasons. One reason is that this model gives an idea of the importance of the determinants (education, employment, etc.) of individual life satisfaction. But the question arises, does the relative importance of each explanatory variable in the subjective well-being model match the relative importance of individual’s perceptions of the most important factors to increase overall life satisfaction? For example, if the model suggests that employment status is the most important factor for improving subjective well-being do people perceive this to be true as well? This study …

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 Jan 2012

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 Jan 2012

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 Jan 2012

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 …


Ab Diblock Copolymer Nanoparticles Via Raft-Mediated Polymerization As A Pseudostationary Phase For Electrokinetic Chromatography, Andre Umansky Jan 2012

Ab Diblock Copolymer Nanoparticles Via Raft-Mediated Polymerization As A Pseudostationary Phase For Electrokinetic Chromatography, Andre Umansky

Graduate Student Theses, Dissertations, & Professional Papers

Electrokinetic chromatography (EKC) is a powerful analytical technique where analytes are separated according to their interactions with the pseudostationary and mobile phases within an electric field. Pseudostationary phases (PSPs) are an integral part of EKC and currently there are a limited number of PSPs available. As the fields of medicinal, environmental, and forensics chemistry grow, the necessity for PSPs with varied selectivity and high efficiencies becomes apparent. Until recently, polymeric synthesis of novel PSPs has been difficult due to the lack of control in structure and size distribution. Recent developments in polymeric synthesis, utilizing the Reversible addition−fragmentation chain-transfer polymerization (RAFT) …


Conserving Montana's Sagebrush Highway: Long Distance Migration In Sage-Grouse, Rebecca Elizabeth Smith Jan 2012

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 …


Influence Of Positive Expectancies And Adaptive Goal Investment On Relationship Abuse, Geniel H. Armstrong Jan 2012

Influence Of Positive Expectancies And Adaptive Goal Investment On Relationship Abuse, Geniel H. Armstrong

Graduate Student Theses, Dissertations, & Professional Papers

According to the Bureau of Justice Statistics 21.5% of women and 3.6% of men were identified as victims of intimate partner violence (IPV) between 2001 and 2005 (Catalano, 2007). However, it is likely that these are underestimated rates due to un-reported incidents of IPV. A national survey conducted by the Centers for Disease Control and prevention found that 35.6% of women and 28.5% of men reported having experienced rape, physical violence, and/or stalking by an intimate partner at some time in their life (Black, Basile, Breiding, Smith, Walters et al., 2011). Several attempts have been made to address the problem …


Classifying Emotion Using Streaming Of Physiological Correlates Of Emotion, Nathan J. Elmore Jan 2012

Classifying Emotion Using Streaming Of Physiological Correlates Of Emotion, Nathan J. Elmore

Graduate Student Theses, Dissertations, & Professional Papers

The ability for a computer to recognize emotions would have many uses. In the field of human-computer interaction, it would be useful if computers could sense if a user is frustrated and offer help (Lisetti & Nasoz, 2002), or it could be used in cars to predict stress or road rage (Nasoz, Lisetti, & Vasilakos, 2010). Also, it has uses in the medical field with emotional therapy or monitoring patients (Rebenitsch, Owen, Brohil, Biocca, & Ferydiansyah, 2010). Emotion recognition is a complex subject that combines psychology and computer science, but it is not a new problem. When the question was …
