Making The Most Of People We Do Not Like: Capitalizing On Negative Feedback, Christopher Edward Anderson

Graduate Student Theses, Dissertations, & Professional Papers

Capitalization was first articulated by Langston (1994) to describe how individuals increase their own positivity by sharing good news with others. This study tests the idea that sometimes people share positive news with others they do not like in an attempt to savor their dissatisfaction with shared accomplishments. A fully crossed randomized 2 X 2 experiment was used to set an initial impression (positive or negative) followed by an interview procedure where the participants would disclose some recent positive event and the confederate interviewer would provide feedback (positive or negative). This procedure was used to test capitalization processes in a …

Negative Allosteric Modulation Of Nmda Receptors With Glun2a Gain-Of-Function Mutations, Jill Christine Farnsworth

Graduate Student Theses, Dissertations, & Professional Papers

N-methyl D-aspartate (NMDA) receptors are calcium permeable, glutamate-gated ion channels that mediate many forms of synaptic plasticity in the central nervous system. Due to their pivotal role in regulating synaptic plasticity, a canonical correlate of the molecular and cellular basis for learning and memory, they are implicated in the pathophysiology of various neurological disorders. Recently, advances in genome sequencing has identified the NMDA receptor to be intolerant to genetic variation, as variation often leads to disease. For example, mutations in the GluN2A subunit of the NMDA receptor are implicated in the etiology of severe epilepsy-aphasia spectrum disorders. Here we selected …

Investigation Of The Tribal Park Concept And Opportunities For The Blackfeet Nation, Iree Schmautz Wheeler

Graduate Student Theses, Dissertations, & Professional Papers

The Tribal Park model is an emerging tool being used by indigenous groups in the United States and Canada for the management of unique and sacred natural areas, in some cases setting aside existing indigenous owned land, and in others regaining control of land management decisions in traditional territory. Currently in North America there are several sites that have self-identified as Tribal Parks. There is a lack of research regarding Tribal Park development in North America, which creates challenges for indigenous groups interested in pursuing a conservation designation of this type. Using an analysis of five Tribal Park case studies …

New, Multi-Scale Approaches To Characterize Patterns In Vegetation, Fuels, And Wildfire, Christopher Jacob Moran

Graduate Student Theses, Dissertations, & Professional Papers

Pattern and scale are key to understanding ecological processes. My dissertation research aims for novel quantification of vegetation, fuel, and wildfire patterns at multiple scales and to leverage these data for insights into fire processes. Core to this motivation is the 3-dimensional (3-D) characterization of forest properties from light detection and ranging (LiDAR) and structure-from-motion (SfM) photogrammetry. Analytical methods for extracting useable information currently lag the ability to collect such 3-D data. The chapters that follow focus on this limitation blending interests in machine learning and data science, remote sensing, wildland fuels (vegetation), and wildfire. In Chapter 2, forest canopy …

Graduate Student Theses, Dissertations, & Professional Papers

Traditional ecological knowledge (TEK) specific to plants has been developed over long-term connections to the environment, diligent observations, and practical experience by Indigenous communities. The traditional ecological knowledge of Indigenous peoples is a vital source for the contextualization and further understanding of past human environmental relationships in the Sunlight Basin of northwestern Wyoming. The Eastern Shoshone people, among many other groups, traditionally occupied the Sunlight Basin of northwestern Wyoming, a region of the Greater Yellowstone Ecosystem. There is a growing necessity for collaboration with Indigenous populations within archaeological and anthropological research. The aim of this project is to develop a …

Assessing The Robustness Of Time-To-Event Abundance Estimation, Kenneth E. Loonam

Graduate Student Theses, Dissertations, & Professional Papers

Abundance estimates can inform management policies and are used to address a variety of wildlife research questions, but reliable estimates of abundance can be difficult and expensive to obtain. For low-density, difficult to detect species, such as cougars (Puma concolor), the costs and intensive field effort required to estimate abundance can make working at broad spatial and temporal scales impractical. Remote cameras have proven effective in detecting these species, but the widely applied methods of estimating abundance from remote cameras rely on some portion of the population being marked or uniquely identifiable, limiting their utility to populations with naturally occurring …

Developmental, Ecological, And Life History Influences On Predator-Induced Plasticity In Songbirds, James Christopher Mouton

Graduate Student Theses, Dissertations, & Professional Papers

Predation is a ubiquitous ecological force that plays a major role in the evolution of phenotypes. Where the predation risk is predictable and variable, prey species are expected to evolve plasticity in traits that reduce the likelihood of being killed and eaten by predators. Such plasticity may be especially critical for the survival of dependent offspring because they are particularly vulnerable to predators and suffer high levels of predation across taxa. Yet the fitness effects of predator-induced plasticity can vary across life stages, differ between parents and offspring, or be mediated by interactions with other species in the community. The …

Local Knowledge And Climate Information: The Role Of Trust And Risk In Agricultural Decisions About Drought, Adam J. Snitker

Climate change is projected to dramatically impact agricultural production across the world. Agricultural producers must adapt to changing conditions by implementing practices and utilizing knowledge that creates resilient operations. This study explores how Montana farmers and ranchers use of different types of knowledge during periods of drought and how risk perceptions and trust influence the use of knowledge. To understand the role trust and risk in producers’ use of local knowledge and climate information, I conducted five focus groups with 34 Montana agricultural producers. Producers explained that they encounter many agriculture-related risks, including uncertain forecasts, financial losses, and adverse weather. …

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 …

Estimates Of Forest Characteristics Derived From Remotely Sensed Imagery And Field Samples: Applicable Scales, Appropriate Study Design, And Relevance To Forest Management, John S. Hogland

Graduate Student Theses, Dissertations, & Professional Papers

Information and knowledge about a given forested landscape drives forest management decisions. Within forest management though, information that adequately describes various characteristics of the forested environment in the spatial detail desired to make fully informed management decisions is often limited. Key metrics such as species composition, tree basal area, and tree density are typically too expensive to collect using ground-based inventory methods alone across broad extents for forest level planning (thousands of ha) at fine spatial detail that permit use at tactical spatial scales (tens of ha). However, quantifying these metrics accurately, in spatial detail, across broad landscapes is important …

Methods For Analyzing High Dimensional Data With Applications To The Wearable And Microbiome Data Analysis, Quy Xuan Cao

Prevention Of Crystalline Silica-Induced Inflammation By The Anti-Malarial Hydroxychloroquine, Rachel Dawn Burmeister

Graduate Student Theses, Dissertations, & Professional Papers

Exposure to inhaled crystalline silica (cSiO2) is common in occupations where there is cutting, milling, or grinding of cSiO2 containing material. The Occupational Safety and Health Administration estimates that over 2 million workers may be exposed to inhaled cSiO2 in the United States. Inhalation of cSiO2 causes acute and chronic inflammation and may lead pulmonary diseases such as silicosis, as well as an increased risk of developing autoimmune diseases.Unfortunately, treatment of cSiO2-induced lung diseases is limited and primarily focused on supportive care.

Inflammation caused by cSiO2 begins when, cSiO2 particles are phagocytized by alveolar macrophages. Interaction between the particle and …

Can Nonhumans Be Victims Of Genocide?, Kirstin Waldkoenig

Graduate Student Theses, Dissertations, & Professional Papers

“Genocide” appears commonly in critical animal studies literature and sparsely in philosophy to describe human-caused violence against nonhuman beings. However, such uses of the term have rarely been informed by relevant work in genocide studies, nor otherwise formally substantiated. This thesis explores what is at stake when employing the term and proposes a model for appropriate application to nonhuman contexts. Claudia Card’s notion of genocide as social death allows for the consideration of nonhuman animals as victims of genocide. Social vitality is important to the lives of some nonhuman animals and its forcible diminishment results in social death for those …

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 …

Probing Denatured State Conformational Bias In 3-Helix Bundles With Foldable Or Intrinsically Disordered Domains, Moses Joseph Leavens

Graduate Student Theses, Dissertations, & Professional Papers

Protein misfolding is associated with several life threatening diseases – Alzheimer’s, Parkinson’s, Cystic fibrosis, Sickle cell anemia, and the Transmissible spongiform encephalopathies, to include Chronic Wasting disease, Scrapie, and Creutzfeldt-Jakob disease. To provide insight into protein misfolding, it is beneficial to understand how an amino acid sequence encodes structure. Once thought to behave as random coil polymers under denaturing conditions, an abundance of recent evidence suggests denatured proteins retain ‘non-random’ or residual structure, which may bias a protein chain to fold efficiently to its native conformer. Probing energetics of residual structure in denatured proteins is challenging, given the shortage of …

Impacts Of Trogocytosis-Mediated Intracellular Signaling On Cd4+ T Cell Effector Cytokine Production And Differentiation, Steven James Reed

Graduate Student Theses, Dissertations, & Professional Papers

Trogocytosis is the direct intercellular transfer of membrane and membrane associated molecules. Unlike other passive-membrane transfer events, trogocytosed molecules may remain fully functional and become re-expressed on the surface of the trogocytosis-positive (trog+) recipient. This phenomenon commonly occurs between various cell types, including those of the immune system. CD4+ T cell trogocytosis occurs during their activation by antigen presenting cells (APC). Consequently, the acquired molecules include ligands for signaling receptors on the T cell.

The impacts of CD4+ trogocytosis on the immune response are largely unknown. While it has been demonstrated that trog+ cells can present trogocytosed peptide:MHC (pMHC), and …

Navigating The Closet: A Mixed Methods Approach To Assessing The Impact Of Concealment On Psychological Outcomes For Sexual And Gender Minorities, James Michael M. Brennan

Graduate Student Theses, Dissertations, & Professional Papers

Background: Sexual and gender minority (SGM) individuals suffer at disproportionate rates of depression, anxiety, and substance use, among other mental and physical health outcomes, compared to heterosexual individuals. Concealment of non-heterosexual sexual identity and/or non-cisgender gender identity may be a key contributor to these disparities. Many SGM individuals engage in concealment as a means to avoid victimization, or because of negative perceptions of their own identity. Concealment as a construct has been conceptualized as comprising cognitive, affective, and behavioral components, each of which individually has been demonstrated to have negative health impacts. Additionally, concealment occurs over time between the intrapersonal …
