Facies Architecture And Controls On Reservoir Behavior In The Turonian Wall Creek Member Of The Frontier Formation, Powder River Basin, Wyoming, Nathan M. La Fontaine

Graduate Student Theses, Dissertations, & Professional Papers

Inter-well heterogeneities influencing fluid migration in deltaic reservoirs are controlled by lateral lithofacies changes and vertical complexities such as low permeability thin-beds. Subsurface tools often cannot predict the spatial and stratigraphic organization of these architectural elements, nor their influence on effective reservoir properties and connectivity. This study integrates sedimentological, stratigraphic, and fluid simulation data to 1) document the facies architecture and depositional evolution of the Turonian Wall Creek Member (WCM) of the Frontier Formation, and 2) quantify the role of multi-scale stratigraphic heterogeneity on reservoir behavior. Upscaled permeability properties derived from fluid simulation of nested, small-scale facies models condition the …

Healing Self And Community: Living Pluralism In The Anishinaabe Paradigm, Andrea A. Fitzpatrick

Graduate Student Theses, Dissertations, & Professional Papers

Abstract: Healing Self and Community: Living Pluralism in The Anishinaabe

This thesis is a study of pluralism through Anishinaabe writers Winona LaDuke, Basil Johnston, Lynn Anderson, and others, focusing on their perceptions and pedagogies and how those perceptions inform pluralistic living. Anishinaabe methodology tends to be innately interconnected, and pluralistic. As such, it can enlighten, heal self-identity structures, and perceptions of the biosphere. I will contextualize how it is necessary to investigate the stories we learn and those we tell, how it is vital to understand where they come from. Included is analysis of how pluralism shows up in mine …

Predictive Spatial Modeling Of Wildfire Occurrence And Poaching Events Related To Siberian Tiger Conservation In Southwest Primorye, Russian Far East, Conor N. Phelan

Graduate Student Theses, Dissertations, & Professional Papers

Siberian tiger (Panthera tigris altaica) populations worldwide have been drastically reduced in number over the past several decades. The Primorye region of the Russian Far East remains one of the final strongholds for the estimated 400 Siberian tigers remaining in the wild. As a flagship species, Siberian tigers play a crucial socio-economic role in helping agencies and non-profits to motivate, fund, and implement broader conservation efforts. Even while defended by organizations such as the Wildlife Conservation Society (WCS), Siberian tigers in Primorye face an onslaught of threats to their continued existence. Profound land use changes due to the …

Factors Influencing Confidence After Multiple Acl Injuries: A Qualitative Case Study, Jacob Casebolt

Graduate Student Theses, Dissertations, & Professional Papers

Background: Anterior Cruciate Ligament (ACL) injuries are common with over 200,000 injuries occurring yearly in the United States. Despite excellent objective measures, only 63% of patients return to their pre-injury level of activity. The low number suggest psychologically mediated disability in ACL reconstruction (ACLR) patients. Purpose: The purpose of this qualitative case study is to describe the confidence of one athlete who underwent multiple ACLR and continued to move into higher levels of competition. Methods: A qualitative case study was conducted with a single women’s soccer player with three ACLR. After a review of the participant’s medical history, the primary …

The Sylvan Blindspot: The Archaeological Value Of Surface Vegetation And A Critique Of Its Documentation, John S. Harris

Graduate Student Theses, Dissertations, & Professional Papers

Surface vegetation at archaeological sites is a resource overlooked in cultural resource management. Drawing upon comparative documentary surveys of site forms and human surveys of 161 archaeologists in 12 U.S. states, this thesis explores why surface vegetation offers archaeological data potential; how archaeological documentation is an artifact of archaeologists, shaped by various subjectivities; and how improvements can be made for vegetal description in cultural inventory site forms. The surveys offer a critique on how the site form records are a product of disciplinary training oversights, differing work background experience, cultural bias, limitations in botanical knowledge, regional differences in U.S. archaeological …

Understanding Changes To Glacier And Ice Sheet Geometry: The Roles Of Climate And Ice Dynamics, Caitlyn Elizabeth Florentine

Graduate Student Theses, Dissertations, & Professional Papers

Glacier and ice sheet geometry depend on climatic and ice dynamic processes that are coupled and often highly complex. Thus, partitioning and understanding the drivers of change to glacier and ice sheet geometry requires creative approaches.

Radiostratigraphy data document emergent layers in the ablation zone of western Greenland that emulate theoretical englacial flow paths. Yet true alignment between radar layers and the englacial flow field can be uncertain because these structures have travelled hundreds of km from their original point of deposition, have been shaped by ice deformation for millennia, and have been subjected to complex and three-dimensional ice motion …

Impacts Of Vegetation Growth On Reach-Scale Flood Hydraulics In A Sand-Bed River And The Implications For Vegetation-Morphology Coevolution, Samuel Box

Graduate Student Theses, Dissertations, & Professional Papers

Vegetation affects river morphology via plant effects on the flow field, sediment transport and deposition, and substrate erodibility. Changes in the flow field caused by above-ground biomass mediate geomorphic response to flooding and habitat suitability for vegetation growth. Using numerical hydraulic models that incorporate drag due to spatially heterogeneous vegetation, I quantify how changes in the antecedent characteristics of woody vegetation in the active channel lead to changes in local bed shear stress, reach-average bed shear stress, and the vegetative component of reach-average total shear stress. Flood hydraulics in turn affect channel morphology and vegetation, providing a feedback mechanism by …

Internal Structure Of Semelfactive Predicates In English, Lynn C. Nelson

Graduate Student Theses, Dissertations, & Professional Papers

This thesis presents an analysis of the internal structure of semelfactive predicates. I propose that the lexical aspect class of semelfactives consists of three sub-categories: (i) semelfactive predicates with internal plurality, (ii) semelfactive predicates which are uni-directional and (iii) semelfactive predicates with plurality of participants. Based on these sub-categories, I further propose that the feature of instantaneity attributed to semelfactives (Smith 1997), should not be used, as semelfactives are in actuality not instantaneous events. Furthermore, I propose that an additional feature of atomicity, which distinguishes between events with plurality and those without, should be added to the binary features of …

Insights Into The Proterozoic To Cretaceous Evolution Of The Western Clearwater Metamorphic Core Complex, Northern Idaho, Through Petrologic And Geochronologic Analysis, Nora Dwyer

Graduate Student Theses, Dissertations, & Professional Papers

The Clearwater metamorphic core complex (CMCC) in northern Idaho contains a rare exposure of the contact of the basal section of the Mesoproterozoic Belt Supergroup with underlying Paleoproterozoic basement. Prior to this study, this contact had not been well documented. In addition, the rocks within the CMCC preserve a complex history of metamorphism, including both Mesoproterozoic and Cretaceous-Eocene regional events. Detrital zircon analysis of five coarsely recrystallized, clean quartzite samples at this contact reveal a bimodal age distribution with peaks at around 1800 - 1900 Ma and 2650 Ma. Several grains are younger than 1700 Ma, with the youngest being …

Examining Upper Extremity Injuries In Male Baseball Players Between The Ages Of 14 To 22 Years Old

Chairperson: Melanie McGrath

The number of upper extremity injuries is increasing in advanced baseball (14 to 22 years old) at an alarming rate. The length of seasons, multiple leagues and the velocity of throwing in overhead sports are the most common causes of elbow and shoulder injuries. In addition, biomechanical variables also influence the risk of injury. Any alteration in range of motion (ROM) directly impacts the biomechanics of overhead activities, such as pitching or …

Annual Climate Impacts On Tree Growth And Post-Fire Regeneration In Ponderosa Pine And Douglas-Fir In The Northern Rocky Mountains, Lacey Hankin

Graduate Student Theses, Dissertations, & Professional Papers

Widespread changes in climate and disturbance regimes, including prolonged drought and increases in the size and frequency of wildfires, have raised concerns regarding forest resilience to environmental change. Dry mixed-conifer forests have persisted for centuries under mixed-severity fire regimes; however, climatically driven increases in the frequency of large wildfires in recent decades may lead to increased tree mortality and declines in post-fire tree regeneration. Climatic warming and increased drought may also impact tree growth, with implications for the carbon cycle. Lower-treeline forests near the edge of their climatic tolerance may be particularly vulnerable to these impacts of future climate warming …

Agency Panic: A Reckoning Of Place, Brock M. Mickelsen

Graduate Student Theses, Dissertations, & Professional Papers

Agency Panic: A Reckoning of Place may be best described as a type of documentation of a conversation between the Gates of the Mountains Wilderness and myself, one where a mutual language is not spoken but one where some understanding can be reached none-the-less. By moving through the landscape without goals or intentions a physical exchange ensues, a push and pull, a call and response, intimacy is gained through tactile experience. Through the use of wet-plate collodion photography I am able to create imagery that engages directly with the place. Its vulnerability records a conversation between two acting powers, artist …

An Inter-Watershed Comparison Study Of Bedrock Controls On Shallow Subsurface Flow And Streamflow Response, Robert Livesay

Graduate Student Theses, Dissertations, & Professional Papers

Bedrock controls on watershed response have been actively studied in recent years, however, most conclusions are based on surface water analysis leaving unresolved questions about the nature of bedrock flow paths and ultimately their control on watershed response. In this study, we investigated bedrock controls on watershed response by simultaneously monitoring the hydrology of two adjacent watersheds underlain by dissimilar geologic formations (monzonite vs. meta-sandstone) and by characterizing subsurface conditions through bedrock drilling and fracture mapping. We hypothesized, when soils saturate, the underlying bedrock geology may influence the partitioning of shallow subsurface flow (SSF) between soil and bedrock flow paths, …

Elucidaton Of The Pysical And Chemical Properties Of Cytochrome C – Cardiolipin Interactions, Margaret Marie Elmer-Dixon

Graduate Student Theses, Dissertations, & Professional Papers

Recently, the electron transport protein Cytochrome c (Cytc) was shown to interact with the mitochondrial lipid cardiolipin (CL) during the initial stages of the intrinsic apoptotic pathway. This interaction is characterized by the protein binding and oxidation of cardiolipin on the concave surface of the outer leaflet of the inner mitochondrial membrane. To date, this interaction has been studied with a variety of methods and techniques reporting varied and often conflicting findings characterizing the nature and extent of the protein-lipid interaction. Cytc has been hypothesized to interact with cardiolipin electrostatically, hydrophobically and through hydrogen bonding and is thought to partially …

Using Astrobiology As A Platform To Study The Impact On The Mathematical Content Knowledge And Pedagogical Content Knowledge Of Elementary Education Majors, Meredith Kay Berthelson

Early mathematical skills have long been hailed as a cornerstone and as the best predictor of later success in mathematics and literacy. This perception highlights the importance of elementary educator’s mathematical content knowledge (MCK) and pedagogical content knowledge (PCK). This study explored a novel approach to motivating and facilitating preservice elementary educators’ engagement in an interdisciplinary context. Astrobiology is a growing interdisciplinary field with extraordinary educational potential. It has the potential to provide an exciting science framework structure to mathematics for preservice educators. Due to its interdisciplinary content, astrobiology offers preservice educators an opportunity to see math content through a …

Evaluation Of Autonomously Measured Alkalinity, Ph, And Pco2 Variability On A Coral Reef, Brittany Peterson

Graduate Student Theses, Dissertations, & Professional Papers

Currently, our understanding of alkalinity (A_T) variability in highly dynamic environments such as coral reefs is limited by the dearth of A_T measurements. In order to better characterize these environments, high temporal resolution A_T data are needed. This work employed the newly developed Submersible Autonomous Moored Instrument for Alkalinity (SAMI-alk), a fully autonomous in situ A_T analyzer, to study seawater A_T variability. The main goals of this research were to evaluate the utility of combining the SAMI-alk data with currently available in situ measurements of pH and partial pressure of carbon dioxide (p …

Respecting Public Investment: The Problems With Democratic Endorsement As A Criterion For Legitimate Value Influence In Science, Rebecca Korf

Graduate Student Theses, Dissertations, & Professional Papers

Criticism of the value-free ideal has motivated attempts to formulate a criterion for the legitimacy of non-epistemic value influence in science. I argue that this search aims to protect two main components of legitimacy, scientific integrity and justice. While integrity is primary, justice remains important, especially in setting scientific goals. One of the main proposals for setting legitimate goals is to rely on democratic endorsement (Intemann 2015). I critically assess four interpretations of this criterion, finding that all are problematic. I then propose and evaluate three alternative models that seek to better balance respect for the public with scientific expertise.

The Effect Of Female Priming On Male Betta Splendens, Susan Greene

Graduate Student Theses, Dissertations, & Professional Papers

Male betta fish are naturally aggressive to attract a mate and defend a territory. This makes them a good model for studying aggression and choice behavior. This study looked at male Betta splendens aggressive nature when impacted by priming with a female and exposure to the SSRI drug fluoxetine. Males in the study received a prime before each choice trial, and the latency for each choice was measured and analyzed. We found no significant differences for preference for a mirror versus a non-mirror trail, or latency for choice for the mirror. However, a significant effect was found for fighting data, …

Avian Community Responses To Bison Grazing In North American Intermountain Grasslands, Danielle A. Fagre

Graduate Student Theses, Dissertations, & Professional Papers

Grassland and shrubland songbird species are a guild of conservation concern in North America. Many of these species have experienced severe population declines, due to habitat loss and land use change. This makes the conservation and management of remaining habitat of crucial importance for this guild. Grazing by large herbivores is an ecosystem process in grassland systems, and in North America, one of the major historic grazers was the Plains bison (Bison bison). Bison are considered ecosystem engineers, because they modify habitat to be more or less suitable for other species, such as grassland and shrubland songbirds. Bison …

Biotic Pulses, Bryotic Pulses And The Effects Of Mosses On Communities And Ecosystems, Mandy Lynn Slate

Graduate Student Theses, Dissertations, & Professional Papers

Non-vascular mosses are known to be ecologically influential and structure communities through their physiological and physical attributes. My dissertation had two objectives. The first goal was to understand how fundamental differences in the physiology of mosses might drive much of their ecological impact. Mosses frequently and rapidly fluctuate between dehydration and rehydration. During these transitions, the cellular integrity of moss is compromised and intra-cellular contents (carbohydrates, amino acids, and ionic compounds) are released. Thus during wet-dry transition periods, mosses have the potential to release pulses of nutrients which may have important effects on other species. However, few studies have explored …

Using Multiple Environmental Tracers To Investigate The Relative Role Of Soil And Deep Groundwater In Stream Water Generation For A Snow-Dominated Headwater Catchment, Isabellah V. Von Trapp

Graduate Student Theses, Dissertations, & Professional Papers

In this study, seasonal fluctuation of environmental tracers in stream flow, soil water, and deep bedrock groundwater were used to constrain the role of deep bedrock groundwater in streamflow generation for a mountainous headwater catchment. Synoptic measurements of stream discharge, ²²²Rn, specific conductivity and major ion concentrations were measured throughout the water year over a 5 km reach of Cap Wallace Creek in the Lubrecht Experimental Forest, Montana, U.S.A. with the intention of understanding groundwater – surface water interactions across spatial and temporal scales. Stage measurements were continually recorded at seven stilling well locations along the reach. Discharge measurements …

The Ethosophy Of The Grizzly Man: Timothy Treadwell's Three Ethologies, Blake L. Ginsburg

Graduate Student Theses, Dissertations, & Professional Papers

This paper explores the ethical appropriateness and significance of Timothy Treadwell’s life among the bears and foxes of Alaska’s Katmai National Park and Preserve. In an attempt to reveal the formative and transformative aspects of Treadwell’s project, I rely upon an ethological framework developed by Matthew Calarco that moves beyond the narrow conception of ethology as a scientific practice aimed at systematic and rigorous documentation of the quantifiable aspects of animal behavior. While many people might be hesitant to conceive of Treadwell’s project as an ethological one, I hope to illuminate the ways in which his life among bears and …

Policy Analysis: Alaska Salmon Hatcheries, Jessica Eller

Graduate Student Theses, Dissertations, & Professional Papers

Using an adapted Ecological Risk Assessment (ERA) - Evaluation, this study analyzes policy regulating Alaska salmon hatcheries to evaluate its effectiveness at sustaining wild salmon runs.When Alaska became a state in 1959, its salmon industry was suffering from years of overfishing. Runs were at an all-time low, prompting constitutional drafters to mandate management of salmon via the sustained yield principle. The hatchery system that operates today and is responsible for a third of the commercial catch each year was put in place in the 1970s to help supplement depressed salmon runs. The effects of hatchery salmon on wild salmon populations …

40 Years On The International Flathead: An Assessment Of Transboundary River Governance, Jedd Sankar-Gorton

Graduate Student Theses, Dissertations, & Professional Papers

Global population growth, climate change, and industrialization, are putting extreme pressures on worldwide freshwater supplies (Cosens 2010). Of the global freshwater supplies, transboundary water sources play a crucial role in sustaining populations. Over 40% of humans on Earth rely on a transboundary river or lake for access to water, and 90% of the world’s population lives in countries that share bodies of water with at least one other country (UN 2008). Taken together, the motivations for improving governance of transboundary water systems have never been stronger. To meet the challenges associated with transboundary water governance, researchers working at multiple scales …
