Investigating The Utility Of Video Modeling Interventions For Generalization Of Social Skills, Laura Ambrose

Graduate Student Theses, Dissertations, & Professional Papers

Social skill deficits are a core, defining feature of Autism Spectrum Disorder. As such, many of the available interventions for children and youth with autism are designed to target social skill development. Although many of these interventions purport to be an effective means of teaching social skills to children and youth with autism, many are lacking in empirical evidence and do not satisfy criteria for evidence-based practice. Encouragingly, video modeling interventions have been deemed an evidence-based practice for children and youth with autism. Research demonstrates that video modeling interventions can prove an effective means for the generalization of skills, a …

Aerodynamics And Ecomorphology Of Flexible Feathers And Morphing Bird Wings, Brett Klassen Van Oorschot

Graduate Student Theses, Dissertations, & Professional Papers

Birds morph their wings during a single wingbeat, across flight speeds, and among flight modes. Such morphing may allow them to maximize aerodynamic performance, but this assumption remains largely untested. We tested the aerodynamic performance of swept and extended wing postures of 13 raptor species in three families (Accipitridae, Falconidae, and Strigidae) using a propeller model to emulate mid-downstroke of flapping during takeoff and a wind tunnel to emulate gliding. Based on previous research, we hypothesized that 1) during flapping, wing posture would not affect maximum ratios of vertical and horizontal force coefficients (CV:CH), and that 2) extended wings would …

The Business Of Empire: American Capitalists, The Nicaraguan Canal, And The Monroe Doctrine, 1849-1858, Jonathan D. Del Buono

Graduate Student Theses, Dissertations, & Professional Papers

In the mid-nineteenth century, U.S. policymakers designed foreign policy to enhance the reach of American commerce and create a commercial empire in and through Latin America. To create this empire U.S policymakers wanted to construct a canal through Central America, which they envisioned as a joint enterprise between American businesses and the federal government. In 1849, Cornelius Vanderbilt and his associates reserved a charter from the Nicaraguan government to build and operate a canal and transit route through their county. Yet competition between varied business interests prompted the U.S. destruction of the Nicaraguan port city of San Juan del Norte …

K-Mer Analysis Pipeline For Classification Of Dna Sequences From Metagenomic Samples, Russell Kaehler

Graduate Student Theses, Dissertations, & Professional Papers

Biological sequence datasets are increasing at a prodigious rate. The volume of data in these datasets surpasses what is observed in many other fields of science. New developments wherein metagenomic DNA from complex bacterial communities is recovered and sequenced are producing a new kind of data known as metagenomic data, which is comprised of DNA fragments from many genomes. Developing a utility to analyze such metagenomic data and predict the sample class from which it originated has many possible implications for ecological and medical applications. Within this document is a description of a series of analytical techniques used to process …

Epistemically Detrimental Dissent In Climate Science, Iheanyi Amadi

Graduate Student Theses, Dissertations, & Professional Papers

Dissent, criticism and controversy are integral to scientific practice, especially when we consider science as a communal enterprise. However, not every form of dissent is acceptable in science. The aim of this paper is to characterize what constitutes the kind of dissent that impedes the growth of knowledge, in other words epistemically detrimental dissent (EDD), and apply that analysis to climate science. I argue that the intrusion of non-epistemic considerations is inescapable in climate science and other policy-relevant sciences. As such there is the need to look beyond the presence of non-epistemic factors (such as non-epistemic risks and economic interests) …

Enclosed From All Sides: Reading Contact And Ambivalence In The Imaginary Al-Andalus Of Hrotsvit's The Passion Of Pelagius And The Song Of Roland, Briana J. Wipf

Graduate Student Theses, Dissertations, & Professional Papers

Hrotsvit of Gandersheim’s The Passion of Pelagius and The Song of Roland have never been read together in terms of their shared engagement with the Muslim other in the Iberian Peninsula, known during the Middle Ages as Al-Andalus. This project is a comparative reading of the texts’ approach to the presentation of an imaginary Al-Andalus as a space of alterity. The texts’ emphasis on imaginative as opposed to accurate portrayals of Andalusian history and Islamic culture suggests their engagement with a process of Christian identity-building, where the “Christian,” as portrayed in each text, is defined against and in comparison to …

Drivers And Feedbacks Of The Fire-Grazing Interaction In The Northern Great Plains, Jacob E. Powell

Graduate Student Theses, Dissertations, & Professional Papers

The fire-grazing interaction is well studied in mesic grasslands worldwide, but research is lacking in semiarid systems. In addition, the fire-grazing interaction reduces the invasion of exotic forage species in mesic grasslands by increasing the scale of grazing selection and may be a tool to control invasive plants in other grasslands. We examined the principal drivers and feedbacks of the fire-grazing interaction on the strength of cattle grazing selection, forage quantity and quality, and vegetation structure and composition in two pastures in northeast Montana at The Nature Conservancy’s Matador Ranch. We also determined the influence of time since fire, within …

At the Crescent Creek Complex near Cooper Landing, Alaska the team discovered various evidences of an ancient Denai’na village complex. What makes this project unique, however, is the collaboration between field school students and Kenaitze interns to …

Ground Fires: Essays On Land And Scouting, Matthew R. Hart

Graduate Student Theses, Dissertations, & Professional Papers

Ground Fires is a collection of creative nonfiction probing the social and environmental complexities that marked the narrator’s long membership in the Boy Scouts of America. I grew up a Scout, part of a quirky, adventurous troop in a New England college town. After earning Eagle and graduating high school, I moved west, working for seven summers and a few more seasons at Philmont Scout Ranch in northern New Mexico. I led backpacking trips through the mountains and high desert, teaching teenagers about land I knew and loved, land that was changing fast. From bears to wildfire to challenging politics, …

Coupling Biophysical Complexity And Forest Metabolism In A Floodplain Landscape, Peter Davis

Graduate Student Theses, Dissertations, & Professional Papers

Floodplains are biophysically complex systems that are considered among the most productive and biodiverse ecosystems on Earth. Until recently, quantitative assessment of the relationship between complexity and terrestrial production has been constrained by technological limitation. To address how floodplain biophysical complexity and ecosystem function are related, I employed remote sensing, GIS, and spatial analyses to quantify and couple metrics of complexity and terrestrial production, as well as explore the relationship among complexity, vegetation structural diversity, and terrestrial primary productivity. The study site is a 6.75-km by 1.75-km portion of the Bitterroot River floodplain near Carlton, MT upon which 551 sample …

Estimating The Effects Of Overstory Retention, Vegetative Competition, And Site Quality On The Height Growth Of Small Ponderosa Pine Trees Using Regression Quantiles, Colin P. Kirkmire

Graduate Student Theses, Dissertations, & Professional Papers

Ponderosa pine (Pinus ponderosa C. Lawson) forests in the Inland Northwestern region of the US are increasingly managed under multi-aged silvicultural systems that provide stand structure for wildlife habitat, timber production, enhanced aesthetic, or restoration of presettlement conditions (O'Hara 2005). Partial retention harvest, where an element of the previous stand's overstory structure is retained, is commonly used to achieve a multi-aged stand structure. However, little is known about how ponderosa pine trees in the understory respond to overstory and understory competitive factors following partial retention harvest. The height growth of small trees was hypothesized to be influenced by site …

A sample of n=63 American Indian Graduate students represented 41 tribes and villages with over 32 unique tribal languages. The respondents indicated …

Visions Of Sovereignty: Tribal Sovereignty Through The Lenses Of Postcolonialism, Indigenous Film, And Visual Anthropology, Martin I. Lopez

Graduate Student Theses, Dissertations, & Professional Papers

Tribal sovereignty has been a topic of discussion since the beginning of colonization in America. Anthropological thought, especially postcolonialism theory, addresses how colonialism can be analyzed to gain a better understanding of Indigenous perspectives on sovereignty. Visual sovereignty, an example of Indigenous Film, is an interdisciplinary approach that can contextualize in specific histories and social interactions all while serving individual tribes, depending on which tribe the filmmaker represents. A film, for instance, can be edited in a way to convey Indigenous ideas of time and space and staged presentations of oral histories that are nearly impossible to display through written …

Descriptive Analysis Of Injuries Sustained By Wildland Firefighters, Taylor Purchio

Graduate Student Theses, Dissertations, & Professional Papers

A Miniaturized Spectrophotometric In Situ Ph Sensor For Seawater, Reuben C. Darlington

Graduate Student Theses, Dissertations, & Professional Papers

Since the Industrial Revolution, the world's oceans have absorbed increasing amounts of CO2 and the resultant changes to the marine carbonate chemical system have reduced the pH by > 0.1 units (~ 30%) in surface waters. This acidification of the oceans has many far reaching impacts on marine life and there is great need of quality instrumentation to assess and follow the changing carbonate system. This MIS project aims to develop a low cost pH sensor with high precision and accuracy for open sea measurements with special emphasis on reduced size and cost. Design effort is based on the commercially available …

Assessing Stream Channel Restoration: The Phased Recovery Framework, Jacob M. Dyste

Graduate Student Theses, Dissertations, & Professional Papers

Channel reconfiguration projects command a large portion of stream restoration resources, while long-term monitoring and research is severely underfunded and rarely implemented. This has led to a limited knowledge base about ecological response and efficacy. Although channel reconfiguration projects are being implemented to restore biological function to lotic systems, the document responses are highly variable and little evidence has shown these projects are reaching their target goals. I predicted the inconsistent response to these projects is the result of disturbance-induced successional processes and catchment-scale water quality impairment. To address how these endogenous and exogenous factors influence stream response to channel …

Are Maximum Ground Forces And Leg Compression In Phase? A Test Of The Classical Spring Mass Model Of Running Gaits, Seth Donahue

Graduate Student Theses, Dissertations, & Professional Papers

The mechanical understanding of human running has classically been described as a spring-mass system, with subsequent models predicting the movements of the body’s center of mass and the forces applied by the leg against the ground. A central requirement of any spring system is the phasic relationship between the length of the elastic elements and the forces applied to these structures. Specifically, elastic elements compress under load and extend as the load is released. We tested whether this model applies to individuals with specialization for extreme performance in human gait. Recent work from elite level sprint runners suggest that their …

Cationic Latex Nanoparticles In Electrokinetic Chromatography: Synthesis, Characterization, And Application To The Separation Of Explosives, Julie Rebecca Mcgettrick

Graduate Student Theses, Dissertations, & Professional Papers

Electrokinetic chromatography (EKC) is a powerful analytical technique that uses the instrumentation of capillary electrophoresis (CE) and the principles of chromatography to separate ionic and neutral analytes. A capillary is filled with background electrolyte (BGE), and when a voltage is applied ionic species migrate to the electrodes. Neutral compounds have no mobility, so a pseudo-stationary phase (PSP) is added to the BGE that consists of an ionic group to provide mobility and a hydrophobic group to interact with analytes. Analytes interact with the PSP which changes their apparent mobilities, leading to a separation. It is possible to coat the negatively …

Subjective Experience Of Empathy In Schizotypy Elicited By Literary Fictional Narrative, Christa "Anahata" Neuman

Graduate Student Theses, Dissertations, & Professional Papers

The elaborate and multidimensional systems that are involved in the personal and subjective experience of empathy are largely unexplored. Nevertheless, when empathy is measured as a static trait there is considerable evidence that individuals diagnosed with schizophrenia and schizotypy demonstrate altered and reduced empathic abilities respectively (Thirioux, 2014). The aim of this study was to investigate the effect that the context of reading literary fiction has on a portion of the process of empathic responding in relation to schizotypal traits, taking into consideration personal factors including current mood. A new measure for the use of momentary assessment of empathy was …

Violence, Catastrophe, And Agency In Nepal: A Deeper Understanding Of The 2015 Earthquakes And Border Blockade, Kassandra D. Viers

Graduate Student Theses, Dissertations, & Professional Papers

In 2015, Nepal was struck by two catastrophes. First, on April 25, a 7.8 magnitude earthquake, followed by hundreds of aftershocks, struck in Gorkha. Then, in September, a blockade was formed that prevented goods from passing through trade checkpoints between India and Nepal. Both of these events highlight social suffering, a form of suffering that refers to the systems of oppression, unequal distribution of resources, and broad social structures that serve to keep certain people impoverished and subjugate. The earthquake caused the most damage to vulnerable people, people already suffering the effects of structural violence. The blockade was created by …

Enhancing Conservation With High Resolution Productivity Datasets For The Conterminous United States, Nathaniel Paul Robinson

Graduate Student Theses, Dissertations, & Professional Papers

Human driven alteration of the earth’s terrestrial surface is accelerating through land use changes, intensification of human activity, climate change, and other anthropogenic pressures. These changes occur at broad spatio-temporal scales, challenging our ability to effectively monitor and assess the impacts and subsequent conservation strategies. While satellite remote sensing (SRS) products enable monitoring of the earth’s terrestrial surface continuously across space and time, the practical applications for conservation and management of these products are limited. Often the processes driving ecological change occur at fine spatial resolutions and are undetectable given the resolution of available datasets. Additionally, the links between SRS …

Potentially Dangerous Enemy Aliens: Experiences At Fort Missoula And Transformative Immigration Policy In The United States, Daniel Smith

Graduate Student Theses, Dissertations, & Professional Papers

In this paper, I attempt to comprehend the experiences of Italian and Japanese internees who were detained at Fort Missoula’s Alien Detention Center during World War II. Furthermore, I draw upon historical patterns of United States’ immigration policies that greatly affected perspectives and social values between various ethnic groups. Simultaneously, national immigration policies shifted across space and time reflecting ethnocentric ideals and discriminatory campaigns that altered past cultural, political, and economic landscapes. The events that produced the internment of Italian and Japanese men at Fort Missoula varied greatly and are critical to examine through historical records. Such records pertain to …

The context of this study is the Mesa Verde Region in the Four Corners of the United States. Specifically, it considers the Ancestral Pueblo archaeology of Montezuma (MT) County, the core area of the Mesa Verde Region, generally considered the most archaeologically dense region in the U.S. These archaeological resources benefit the local and global community by promoting research, education, tourism and cultural heritage. For example, Mesa Verde National Park draws hundreds of thousands of tourists …

Stability Of Cross-Feeding Polymorphisms In Microbial Communities, Ivana Gudelj, Margie Kinnersley, Peter Rashkov, Karen Schmidt, Frank Rosenzweig

Biological Sciences Faculty Publications

Cross-feeding, a relationship wherein one organism consumes metabolites excreted by another, is a ubiquitous feature of natural and clinically-relevant microbial communities and could be a key factor promoting diversity in extreme and/or nutrient-poor environments. However, it remains unclear how readily cross-feeding interactions form, and therefore our ability to predict their emergence is limited. In this paper we developed a mathematical model parameterized using data from the biochemistry and ecology of an E. coli cross-feeding laboratory system. The model accurately captures short-term dynamics of the two competitors that have been observed empirically and we use it to systematically explore the stability …
