Utilization Of Various Methods And A Landsat Ndvi/Google Earth Engine Product For Classifying Irrigated Land Cover, Andrew Nemecek

Graduate Student Theses, Dissertations, & Professional Papers

Methods for classifying irrigated land cover are often complex and not quickly reproducible. Further, moderate resolution time-series datasets have been consistently utilized to produce irrigated land cover products over the past decade, and the body of irrigation classification literature contains no examples of subclassification of irrigated land cover by irrigation method. Creation of geospatial irrigated land cover products with higher resolution datasets could improve reliability, and subclassification of irrigation by method could provide better information for hydrologists and climatologists attempting to model the role of irrigation in the surface-ground water cycle and the water-energy balance. This study summarizes a simple, …

A Capitalist's Social Gospel: Frank Wakeley Gunsaulus And The Promise Of Upward Mobility, 1875-1921, Joshua Pretzer

Graduate Student Theses, Dissertations, & Professional Papers

Frank Wakeley Gunsaulus was a preacher who began his ministry in 1875 as a little-known itinerant Methodist in rural Ohio. Within two decades, he became one of America’s most influential religious figures with a popular style and message of hope for the future. This paper examines the mission of this pulpiteer, who believed Jesus and industrial capitalism could solve the problems of labor conflict, poverty, and sin as the kingdom of God was gradually realized on earth. Where many social gospelers challenged the interests of capital to varying degrees, Gunsaulus was both the businessman’s firm defender and an advocate for …

Longevity In Snowshoe Hares, Katrina L. Theisen, Alexander V. Kumar, L. Scott Mills

Undergraduate Theses, Professional Papers, and Capstone Artifacts

For small mammals subject to predation, individual longevity, or lifespan, is typically unknown. Snowshoe hares (Lepus americanus) are used as the focal species of this study to examine the assumption that small prey species do not typically live past one or two years of age. To test this assumption, we analyzed a 20-year capture-mark-recapture database to first index the lifespan of hares. We analyzed this database to determine which factors increased the odds of longevity in hares. Body condition and capture location were significant in increasing the odds of a hare being long lived, whereas sex of the …

Eating Insects: A Community Action Toolkit, Lily X. Chumrau, Charlotte Langner, Freya Sargent, Ellen Sears, Mary Mccormick

Undergraduate Theses, Professional Papers, and Capstone Artifacts

The world’s human population has risen exponentially over the last 100 years and is expected to reach nine billion by 2050. Ensuring food security and resource sustainability is of global concern. The United Nations Food and Agriculture Organization endorses insect farming as an alternative to cattle, pork, sheep, and poultry industries because of their higher food conversion rate. Insect farming requires less arable land, less water, and produces less greenhouse gases than traditional livestock. The practice of eating insects, known as entomophagy, is not a new idea as two billion people around the world include insects in their diets. Unfortunately, …

Biotic And Abiotic Associations With Westslope Cutthroat Trout (Oncorhynchus Clarkii Lewisi) In The North Fork Flathead River Basin In Northwestern Montana, Usa And Southeastern British Columbia, Can Under Current And Future Climate Scenarios., Kadie B. Heinle, Lisa Eby, Clint Muhlfeld, Vincent D'Angelo, Amber Steed, Andrew Whiteley, Mark Hebblewhite

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Westslope Cutthroat Trout (Oncorhynchus clarkii lewisi; WCT) populations are declining across much of their native range due to threats such as habitat degradation, competition with non-native species, and climate change. Understanding how habitat characteristics impact distributions of nonhybridized WCT populations throughout a relatively pristine core conservation area is needed to inform management and conservation efforts. We investigated whether abiotic (e.g., gradient) and biotic (i.e., Bull Trout – Salvelinus confluentus) variables predicted WCT presence and predicted how future stream temperature projections for the area might be expected to alter distributions. We compared logistic regression models of WCT presence …

The Impact Of Depression On Treatment Outcomes For Patients With Aphasia Who Participate In An Intensive Comprehensive Aphasia Program (Icap), Harley B. Kincheloe

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Abstract

Background: Aphasia is a multi-modal impairment resulting from left-hemisphere stroke. Aphasia is often accompanied by post-stroke depression. Acquiring aphasia and depression is seen to hinder quality of life and rehabilitative outcomes. Traditional stroke therapy often does not monitor or treat psychological difficulties such as depression. Such psychological difficulties hinder progress in recovery and may need to be addressed in therapy to ensure the best possible outcomes.

Aims: In response to the lack of psychological support for persons with aphasia, this literature review aims to explore the impact of depression on functional outcomes. Furthermore, this literature review will explore how …

Avoiding Adverse Effects: New Ideas In Drug Discovery For Targeting Pparγ, Trey M. Patton

Graduate Student Theses, Dissertations, & Professional Papers

Peroxisome proliferator-activated receptor gamma (PPARγ) has been a drug target to treat type 2 diabetes for the last 20 years when rosiglitazone and pioglitazone were approved by the FDA in 1999. While effective at increasing insulin sensitivity, these drugs cause serious adverse effects due to their full agonist characteristics. For that reason, drug discovery efforts have attempted to reduce or prevent the amount of agonist character of new PPARγ targeting ligands. Unfortunately, there have been no new FDA approved drugs for the receptor. There is a need for new ideas to produce better quality pharmaceuticals that lessen the impact of …

Investigating The Effectiveness Of Parent-Implemented Interventions In Improving The Social Skills Of Children With Autism Spectrum Disorder, Zachary R. Shindorf

Graduate Student Theses, Dissertations, & Professional Papers

There has been an increase in the diagnosis of Autism Spectrum Disorder (ASD) in recent years. As a result, many families who have a child diagnosed with ASD seek out effective treatment in improving the social skills of their child. Literature suggests varied results when considering the treatment outcomes of different social skills interventions. However, the use of evidence-based practices (EBP), parent involvement in the treatment, and individualized treatment goals is considered best practice when treating ASD. This study combined the use of three EBPs: video modeling, social narratives and parent implemented intervention (PII), in attempts to effectively improve the …

Modulation Of Cytochrome C’S Peroxidase Activity By Ω-Loops C And D In Monomers And Dimers, Haotian Lei

Graduate Student Theses, Dissertations, & Professional Papers

Mitochondrial cytochrome c is a heme containing protein with flexible heme ligation. Cytochrome c in its native state with Met80 bound to the heme is an electron shuttle in the electron transport chain. Under apoptotic stimuli, cytochrome c oxidizes the mitochondrial lipid cardiolipin, leading to the release of pro-apoptotic factors into the cytoplasm. To oxidize cardiolipin, Met80 in Ω-loop D must be dissociated from the heme iron, which allows cytochrome c to obtain access to alternative conformers. Two segments of cytochrome c, namely Ω-loops C and D, have been suggested to be important in regulating the dissociation of Met80. Unlike …

The Genetic Mechanisms Underlying Pigmentation And Their Evolutionary Importance In Birds, Nicholas David Sly

Graduate Student Theses, Dissertations, & Professional Papers

Integumentary pigmentation is a phenotype of fundamental importance to animals, with major impacts on survival and fitness. Thus, understanding the mechanisms underlying pigmentation can help illuminate general principles about how adaptive variation is generated and maintained in populations. Here, I present a dissertation that is aimed at understanding the developmental, regulatory, and genetic mechanisms that underlie variation in avian plumage color, and their evolutionary importance.

In my first chapter, I addressed how the modular organization of plumage traits may impact their evolution. The production of color in developing feathers is a modular process, with several mechanisms combining to produce the …

A Structural And Biochemical Study On Ric-8a, An Intracellular Guanine Nucleotide Exchange Factor And Folding Chaperone For The Inhibitory G-Protein Alpha Subunit-1, Baisen Zeng

Graduate Student Theses, Dissertations, & Professional Papers

Heterotrimeric G-proteins (Gαβγ) regulate many cellular processes in the G-protein signaling pathways. The α-subunit (Gα) in the heterotrimer is activated by G-protein-coupled receptor (GPCR) as the guanine-nucleotide exchange factor (GEF), which catalyzes the GDP-release and GTP-binding reactions at Gα nucleotide-binding site, at the cell membrane. Intracellular GEFs for Gα subunits have been identified; among them, the mammalian isoform A of resistance to inhibitors of cholinesterase-8 (Ric-8A) catalyzes nucleotide exchange and functions as a folding chaperone for inhibitory Gα (Gαi1). In a nucleotide-free complex with Gαi1, Ric-8A likely assumes the GEF and chaperone roles by inducing a molten globule-like state. Tall …

The Missionary Enterprise, Racial Conflicts, And The Transformation Of American Evangelicalism, 1945-1980, Timothy Paul Ballard

Graduate Student Theses, Dissertations, & Professional Papers

This dissertation examines the history of InterVarsity Christian Fellowship to understand the creation of a color-conscious theological discourse about racial identity and racial pluralism that emerged among evangelicals in the mid-twentieth century. Although a colorblind articulation of racial identity had wide currency among white and black evangelicals as a way to counter segregationists’ claims of racial superiority, it had little effect in challenging the exercise of white hegemony even among those who advocated for racial equality. The limits of colorblindness came to light as black evangelicals forged new approaches to evangelization among African Americans and white evangelicals challenged the validity …

Development Of An Open-Source, Custom Environmental Data Logger For Spatially Scalable Data Collection, Tim Anderson

Graduate Student Theses, Dissertations, & Professional Papers

Characterizing the processes that lead to differences in ecosystem productivity and watershed hydrology across complex terrain remains a challenge. This difficulty can be partially attributed to the cost of installing networks of proprietary data loggers that monitor differences in the biophysical factors contributing to vegetation growth or hydrological processes. Studies that aim to compare concurrent time-series data sets across multiple locations must therefore balance the high cost of these data logger systems with the need for spatial resolution in their data. Here, we present the design, implementation, and case study for an open-source “Pinecone” data logger system, released under the …

Dna Analysis On Ceramic Cooking Vessels, Britney J. Radford

Graduate Student Theses, Dissertations, & Professional Papers

Ceramic vessels are a durable material found in abundance throughout the archaeological record. Organic residue analysis has been used to study ceramic vessels utilizing lipid analysis and protein analysis. Lipids and proteins analysis provide limited information at the genus level, leaving out valuable information that species-specific results can tell us such as unique genetic and environmental information. Lipids and proteins analysis provide limited information at the genus and taxonomic levels leading to issues of misclassification of species. If only certain animals or plants of a genus are being used, then unique genetic and environmental information found only at the species …

Ice Flow Impacts The Firn Structure Of Greenland's Percolation Zone, Rosemary C. Leone

Graduate Student Theses, Dissertations, & Professional Papers

One dimensional simulations of firn evolution neglect horizontal transport as the firn column moves down slope during burial. This approach is justifiable near Greenland's ice divide, where ice flow is near vertical, but fidelity is lost in the percolation zone where horizontal ice flow advects the firn column through climate gradients. We simulate firn evolution processes under advection conditions using a transient, thermo-mechanically coupled model for firn densification and heat transfer with various schemes for meltwater penetration and refreezing. The simulations isolate processes in synthetic runs and investigate an ice core site and four transects of Greenland’s percolation zone. The …

A Dual State Hierarchical Ensemble Kalman Filter Algorithm, William J. Cook, Jesse Johnson, Marko Maneta, Doug Brinkerhoff

Graduate Student Theses, Dissertations, & Professional Papers

Dynamic models that simulate processes across large geographic locations, such as hydrologic models, are often informed by empirical parameters that are distributed across a geographical area and segmented by geological features such as watersheds. These parameters may be referred to as spatially distributed parameters. Spatially distributed parameters are frequently spatially correlated and any techniques utilized in their calibration ideally incorporate existing spatial hierarchical relationships into their structure. In this paper, a parameter estimation method based on the Dual State Ensemble Kalman Filter called the Dual State Hierarchical Ensemble Kalman Filter (DSHEnKF) is presented. This modified filter is innovative in that …

Exploitation Or Empowerment? Women’S Experiences In The Cam Modeling Industry, Ekaterina Bays

Graduate Student Theses, Dissertations, & Professional Papers

Sex work and the experiences of women within it have been studied in-depth over the past four decades. However, the majority of studies on sex work focus on women who work in prostitution, overlooking rapidly growing cam modeling industry and its female workers. Over the past ten years cam modeling has become an increasingly popular adult entertainment industry, gradually displacing traditional pornography from the online sex market (Senft 2008). In this study, I used theoretical frameworks of radical and liberal feminists as well as polymorphous paradigm to investigate if the cam modeling industry is either an empowering or an exploitative …

Treating Trauma Within Rural Schools: An Implementation Science Perspective, Heather Marie Halko

Graduate Student Theses, Dissertations, & Professional Papers

High rates of childhood trauma exposure (65-75%) are concerning given the negative outcomes associated with trauma-related symptoms. Numerous evidence-based practices (EBPs) have been developed to treat posttraumatic stress symptoms; however, schools often experience barriers to implementing these interventions with fidelity. Given the scarcity of service options within rural areas, this qualitative study explored factors that might influence the adoption and implementation of trauma-focused interventions within rural schools using the Consolidated Framework for Implementation Research (CFIR; Damschroder et al., 2009) and the Implementation Outcomes Framework (IOF; Proctor et al., 2011). A semi-structured protocol was used to interview clinicians working in rural …

Ecological Stoichiometry In Watersheds: From Land To Water In The Qinghai Lake Basin, Ze Ren

Graduate Student Theses, Dissertations, & Professional Papers

We examined the influences of grassland status (as indexed by normalized difference vegetation index, NDVI) on carbon (C), nitrogen (N), and phosphorus (P) concentrations and stoichiometry, nutrient limitation, as well as microbial community structure in soil, stream, and/or lake ecosystems in the Qinghai Lake watershed, where grassland is the dominant landcover and more than half of the grassland is degraded.

Chapter 2 showed that grassland degradation decreased C and N concentrations as well as C:N, C:P, and N:P ratios in soil. Moreover, grassland degradation decreased C, N, and P concentrations and influenced C:N and N:P ratios in soil microbial biomass. …

The Impact Of Industrial Agriculture On Social-Ecological Resilience: A Case Study Of The Fairfield Bench, Montana, Anne Preston Harney

Graduate Student Theses, Dissertations, & Professional Papers

Agricultural systems can be understood as social-ecological systems, in which humans and the natural world interact with and influence each other. The concept of resilience within social-ecological systems has gained considerable attention in recent years. Resilience is generally defined as the system’s ability to absorb and adapt to stressors while still maintaining a similar functioning state. With the major challenges created by the overarching system of industrial agriculture, such as weed resistance to herbicides, water pollution, market consolidation, and declining numbers of farmers, resilience in agricultural systems is a critical concept to explore and understand. However, despite the popularity of …
