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 …

Spatiotemporal Dynamics Of Nitrogen And Carbon Biogeochemistry In A Wetland-Stream Sequence, Patrick E. Hurley

Graduate Student Theses, Dissertations, & Professional Papers

Studies of aquatic ecosystems often segregate streams from the influential ponds, lakes, and wetland zones that act as important transitions between terrestrial and fluvial systems. Across the aquatic landscape, these zones interact to form linked ecosystems that function as discrete nutrient processing domains, shifting biogeochemical signals due to spatial and temporal variability in hydrologic and biologic controls. Using a mass-balance approach, we profiled nutrient dynamics along a 23-km wetland-stream sequence over three seasons. Hydrologic, morphologic, and biologic conditions, as well as landscape attributes, were quantified to determine potential controls on biogeochemical cycling in a tributary of the Upper Clark Fork …

Tiger Monitoring In Bhutan Using Non-Invasive Genetic Tools, Tashi Dhendup

Graduate Student Theses, Dissertations, & Professional Papers

Large carnivores are one of the most threatened group of animals in the world. They suffer from prey depletion, persecution by humans, and habitat loss and fragmentation which are extensively driven by anthropogenic activities. One such species is the tiger Panthera tigris. Tigers are found in thirteen countries in Asia and are protected across the range; however, tiger numbers have declined as an after effect of habitat loss, prey depletion and poaching. Human-induced changes have reduced the tiger's historical range to about 7% in which a little more than 3900 tigers are found. Most of these individuals currently exist …

Human Vs. Non-Human Bone: A Non-Destructive Histological Method, Haley N. O'Brien

Graduate Student Theses, Dissertations, & Professional Papers

Species identification is one of the first steps in the analysis of bone fragments in both forensic and archaeological contexts. Current methods for human vs. non-human taxa identification include morphoscopic, histological, and DNA analyses in order to determine forensic significance and assess what is present in an assemblage. This study will use an MA1000 AmScope camera microscope to examine the longitudinally fractured surface of cortical bone fragments to gauge if non-destructive taxa identification is possible from fragmentary remains without morphologically identifying features. This method is testing for a notable difference in human vs. bovid vs. cervid endosteal cortical bone without …

Self-Compassion And Fear Of Compassion As Mediators In The Relationships Of Childhood Invalidation With Emotion Dysregulation And With Borderline Personality Disorder Characteristics, Priyadarshani Florence Loess

Graduate Student Theses, Dissertations, & Professional Papers

According to Linehan’s (1993) biosocial theory, the core feature of Borderline Personality Disorder (BPD) is emotion dysregulation, which arises from emotional vulnerability and an inability to effectively modulate emotional experiences. Linehan posits that the transaction of environmental invalidation with biological vulnerabilities leads to the development of BPD. Those with BPD often live painful, chaotic lives, experience extreme emotions and impulsivity, and engage in self-injurious behavior. While there are treatments with demonstrated effectiveness, they do not work for everyone, and there is a need to continue to advance interventions. Self-compassion is extending nonjudgmental kindness to one’s self during stress, failure, or …

Population And Breeding Ecology Of Sagebrush Steppe Songbirds, Kayla Ann Ruth

Graduate Student Theses, Dissertations, & Professional Papers

Sagebrush steppe is one of the most threatened ecosystems in North America. Domestic livestock grazing is the dominant land use of sagebrush steppe across the west. Rest-rotation grazing systems can be a conservation management tool, most recently, by the Natural Resource Conservation Service - Sage Grouse Initiative (SGI). The goal of SGI is to encourage private landowners to use a livestock grazing regime that maintains or improves habitat for greater sage-grouse (Centrocercus urophasianus), as well as improve rangeland productivity. Songbirds are biological indicators that can assess the health of sagebrush steppe. Avian adult density estimates are often used …

Sexual Dimorphism In Skeletal Trauma Associated With Intimate Partner Violence (Ipv), Keith Biddle

Graduate Student Theses, Dissertations, & Professional Papers

Once known as “Domestic Violence”, Intimate Partner Violence, or IPV, is a problem as old as humanity. Even in our modern era, it continues to plague even the most “enlightened” or “advanced” cultures and societies. Much has been written about the issue from Sociological and psychological aspects and while there is some consensus in the medical field regarding the patterns of injury associated with IPV, that consensus has yet to reach the field of forensic anthropology. It is to this end that this study has been conceived.

The proposed project has three parts. The first part is a validation study …

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 …

Influence Of Large Wood On Sediment Routing In A Mixed Bedrock-Alluvial Stream, Robin Welling

Graduate Student Theses, Dissertations, & Professional Papers

Sediment storage by instream wood in forested mountain streams mediates sediment movement from hillslopes through the channel network and can alter channel morphology at multiple spatial scales. Mixed bedrock-alluvial channels are prevalent in mountain stream networks, yet the distribution and geomorphic impact of large wood within these streams are poorly understood. To estimate how the distribution of large wood in a mixed bedrock-alluvial stream relates to sediment storage, we measured and characterized large wood, and surveyed the volume of associated sediment within a stream in the Bitterroot Mountains, Montana. The upstream portion of the study reach is predominantly alluvial and …

The Effects Of Forest Gaps On Animal Communication Networks, Cedar Arran Mathers-Winn

Graduate Student Theses, Dissertations, & Professional Papers

To avoid predation, many animals have evolved complex systems of anti-predator communication. Alarm calls are a key component of anti-predator behavior in many birds, and can provide detailed information about predators. Additionally, many birds and mammals produce and respond to each other’s alarm calls, creating a complex communication network. Furthermore, individuals may give alarm calls in response to the alarm calls of others nearby, without actually seeing a predator. This makes possible the spatial spread of alarm information, which can result in complex communication networks extending over a large area. However, this requires suitable habitat in which birds will be …

Pattern-Process Linkages In Forested Ecosystems, Eryn Elizabeth Schneider

Graduate Student Theses, Dissertations, & Professional Papers

Ecological pattern-process linkages have been called the Rosetta’s stone of ecology. The pattern-process linkage is a feedback whereby ecosystem processes drive structural patterns, and vegetation patterns also strongly influence vital ecosystem processes. The role of competition and gap dynamics in creating spatial heterogeneity was assessed in Sitka-spruce western hemlock forests. Results indicated that despite low species richness, these forests are structurally diverse with the spatial imprint of competition obscured by gap dynamics through stand development. The influence of forest structural and spatial heterogeneity on snow accumulation and persistence was examined in a mixed-conifer forest. Tree neighborhood type (open, clump, individual) …

Cognitive Impacts Of Age Based Stereotype Threat In Older Adults, Cali Caughie

Graduate Student Theses, Dissertations, & Professional Papers

The present study examined the effects of age-based stereotype threat (ABST) exposure on cognitive performance in older adults. Forty-nine community volunteers age 65 and older were stratified by age and gender and then randomly assigned to either an ABST group or a Control group. The ABST group read a paragraph describing the expected negative effects of age on cognition and the prevalence of Alzheimer’s disease in older adults. Participants in the Control group read a neutral paragraph of similar length and difficulty. It was hypothesized that individuals in the ABST group would perform worse on neuropsychological testing than individuals in …

"Fenced-In Place": White Settler Colonialism As Opposition To Increased Tribal Management Of The National Bison Range, Brittany Lee Palmer

Graduate Student Theses, Dissertations, & Professional Papers

Since the Tribal Self Governance Act was passed in 1994, the Confederated Salish and Kootenai Tribes (CSKT) in western Montana have sought increased management responsibilities at the National Bison Range, which is fully encompassed by the Flathead Indian Reservation. Though the U.S. Fish and Wildlife Service has managed the Bison Range since it was established in 1908, the Tribes assert that they were the original stewards of bison in the area, and have requested both the reinstatement of the National Bison Range to Tribal trust ownership and increased management responsibilities through negotiated Annual Funding Agreements with the Department of Interior. …

An Assessment Of Fecal Water Contamination In The Absaroka-Beartooth Wilderness, Daniel Paul Pendergraph 5024527

Graduate Student Theses, Dissertations, & Professional Papers

Wilderness water sources are often defined as pristine or high quality due to the lack of point source pollution. Non-point source pollution from recreation to water resources can be extensive and is well-studied in protected areas globally. Bacterial contamination, specifically fecal bacteria, poses a significant threat to human health because of the risk for outbreaks of illness and disease. Water sources in designated Wilderness areas are particularly vulnerable to fecal water contamination due to high volume of backpackers and lack of backcountry waste facilities. To estimate the occurrence of fecal water contamination in Wilderness water resources, an exploratory analysis was …

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 …

Multinucleated Giant Cell Formation And Phenotype, Kevin Lewis Trout

Graduate Student Theses, Dissertations, & Professional Papers

Multinucleated giant cells (MGC) are homotypic macrophage syncytia associated with granulomas. Despite their correlation with pathology, MGC functional contributions to inflammation are relatively unknown. The objective of this work was to gain an understanding of MGC phenotype. First, techniques were developed to better enable the study of these cells in vitro. Second, inorganic particles known to cause inflammation were observed to cause MGC formation in the lungs. Finally, the particle that resulted in the highest macrophage fusion was used together with the in vitro system to compare MGC and macrophage phenotype in response to stimulation. The results contribute to fundamental …

The Alphaback: A Novel Processing Speed Test, Meredith Kathleen Reynolds

Graduate Student Theses, Dissertations, & Professional Papers

Processing speed is a sensitive indicator of normal aging, as well as neurological impairment. Despite the importance of assessing this cognitive domain in neuropsychological assessments, few tests of processing speed are available. The purpose of the current study was to establish the operating characteristics, as well as the convergent and divergent validity of a novel processing speed test, the Alphaback, on a healthy college student population (N = 91). The Alphaback is a 2 min computerized task in which examinees must orally state the alphabetical letter that precedes the letter presented on a screen as fast as possible. Cognitive tests …
