An Empirical Investigation Of The Buddhist Concept Of "Not-Self", Christian Herwitz
An Empirical Investigation Of The Buddhist Concept Of "Not-Self", Christian Herwitz
Graduate Student Theses, Dissertations, & Professional Papers
All individuals have notions about how they would likely approach themselves under times of stress, as well as the ways which would be most helpful to them. The present study investigated four broad ways of approaching the self under stressful circumstances: self-esteem, self-control, self-compassion, and not-self. Not-self, a concept based in Buddhist philosophy, is novel to a Western population, and was the primary focus. In order to comprehensively examine the concept, data were collected from 168 undergraduates on responses to stressful circumstances: by bolstering self-esteem, engaging in self-control behaviors, engendering a sense of self-compassion, or accepting/letting go thoughts, feelings, wants, …
Contrasting Two Prophylactic Dysphagia Interventions For Patients With Head And Neck Cancer Treated With Radiotherpy With Or Without Adjunctive Chemotherapy, Laurie Slovarp
Graduate Student Theses, Dissertations, & Professional Papers
Many patients with head and neck cancer (HNC) suffer from dysphagia caused by organ preserving regimens of radiation therapy with or without adjunctive chemotherapy. Prior research has shown a benefit of prophylactic dysphagia intervention; however, prior studies vary in terms of timing, dosage, and types of treatments prescribed. Additionally, compliance to prophylactic swallowing exercises (PSEs) has been poor and anecdotal evidence points towards swallowing pain as a cause of poor compliance. This prospective study investigated exercise compliance, oral intake, self-perceived swallowing function, swallowing-related quality of life, and swallowing-related pain for patients who received two different types of prophylactic swallowing interventions. …
Taphonomy Of The Chengjiang Biota: Using A Combination Of Sedimentology, Geochemistry And Experimental Taphonomy To Determine Preservation, Lindsay Ann Mackenzie
Taphonomy Of The Chengjiang Biota: Using A Combination Of Sedimentology, Geochemistry And Experimental Taphonomy To Determine Preservation, Lindsay Ann Mackenzie
Graduate Student Theses, Dissertations, & Professional Papers
The Chengjiang Biota, found in the Early Cambrian Maotianshan Shale (Yunnan, China), represents the Cambrian ôexplosion of life,ö providing a snapshot of the early evolution and development of complex life. This snapshot is possible because high fidelity processes transfer information from living organisms to preserved fossils. Taphonomy is everything that occurred during this information transfer from death to fossilization and discovery, including chemical and/or sedimentological processes. The Chengjiang fossilsÆ biology is well documented and taphonomical processes have been proposed. Tests of these models are limited because the depositional environment remains poorly understood. To fill this gap and better constrain the …
The Biogeochemistry Of Elemental Sulfur Contaminated Soils: Insights Into Effective Remediation, Michael Ryan Mctee
The Biogeochemistry Of Elemental Sulfur Contaminated Soils: Insights Into Effective Remediation, Michael Ryan Mctee
Graduate Student Theses, Dissertations, & Professional Papers
Soil contamination that results from elemental sulfur (S0) deposition is a new occurrence. Elemental sulfur is stockpiled as a byproduct from the oil and gas industry and is deposited by biodegradable trap and skeet targets at shooting ranges. Chemolithotrophs and mixotrophs can oxidize S0 to H2SO4. Consequently, in areas where excess S0 is deposited or stockpiled, soils can acidify to pH values observed with acid mine drainage.
I studied S0 contamination at a former sporting clay range. For seven years, the range used biodegradable trap and skeet targets that contained S …
The Effect Of Spatial Patterns Of Soil Hydraulic Conductivity And Depth On Local And Hillslope Scale Shallow Water Table Dynamics, Casey E. Ryan
The Effect Of Spatial Patterns Of Soil Hydraulic Conductivity And Depth On Local And Hillslope Scale Shallow Water Table Dynamics, Casey E. Ryan
Graduate Student Theses, Dissertations, & Professional Papers
Much research in forested headwater catchments has focused on the role of topography for organizing subsurface flow and the hydrologic connectivity of upland flow paths to stream networks. However, little work has been conducted to evaluate how localized and hillslope scale patterns of hydraulic conductivity and soil depth contribute to spatial patterns of water table duration, magnitude, and connectivity. I monitored shallow groundwater dynamics in wells distributed across a 1st order hillslope in the Lubrecht Experimental Forest, Montana. Additionally, I collected in-situ measurements of soil saturated hydraulic conductivity and soil depth at 10m intervals across the study hillslope and compared …
The Tower Of Hanoi In Dynamic Creative Problem Solving, Lia Harrington
The Tower Of Hanoi In Dynamic Creative Problem Solving, Lia Harrington
Graduate Student Theses, Dissertations, & Professional Papers
Creativity and emotions are well-studied constructs, and there is much work on their interrelations. However the empirical application of dynamical systems analysis to them is still relatively rare. For these reasons, a study was conducted on the dynamics and interrelationships of creativity, emotion, and psychopathology using state space grids (SSG) in 33 young adult participants assessed for autism spectrum and negative schizotypy traits, using a computerized Tower of Hanoi (ToH) creative problem-solving task. An overview of the dual importance of convergent and divergent thinking styles to creativity is provided as a context for the experiment. The hypothesis that participants with …

Forest Fire Risk Assessment Using Point Process Modeling & Monte Carlo Fire Simulation: A Case Study In Gyeongju, South Korea, Hyeyoung Woo
Forest Fire Risk Assessment Using Point Process Modeling & Monte Carlo Fire Simulation: A Case Study In Gyeongju, South Korea, Hyeyoung Woo
Graduate Student Theses, Dissertations, & Professional Papers
Forest fire risk assessment becomes critical for developing forest and fire management strategies in Korea since the magnitude of damage from fires significantly increased over the past decades. Fire behavior probability is one of the major components in quantifying fire risk, and is often presented as burn probability. Burn probability estimation requires a proper estimation of fire occurrence probability because fire spread is largely influenced by ignition locations in addition to other environmental factors, such as weather, topography, and land covers.
The objective of this study is to assess forest fire risk over a large forested landscape in and around …
The Occurrence Of Place-Based Narrative In U.S. Senatorial Campaign Advertisements, Brian K. Munis
The Occurrence Of Place-Based Narrative In U.S. Senatorial Campaign Advertisements, Brian K. Munis
Graduate Student Theses, Dissertations, & Professional Papers
Narratives have been increasingly subject to study within social science disciplines. However, research pertaining to narrative within political campaigns is incomplete. For example, there has been a relative lack of attention in the literature to the symbolic discourse and imagery in many political campaign advertisements that—seemingly—exists in order to link candidates to specific geographic “places” within their constituencies. A more complete understanding of the association between narratives of place and political campaigns will allow us to more effective and accurately gauge how, when, and why candidates use this potential strategy; as well as its possible effectiveness in election outcomes. This …
The Sensitivity Of Soil Respiration To Soil Temperature, Moisture, And Carbon Supply At The Global Scale, Andrew Hursh
The Sensitivity Of Soil Respiration To Soil Temperature, Moisture, And Carbon Supply At The Global Scale, Andrew Hursh
Graduate Student Theses, Dissertations, & Professional Papers
Soil respiration is one of the most important terms in the global carbon budget, yet we know very little about how important environmental factors control this process at the global scale. Soils contain more carbon than terrestrial biomass and the atmosphere combined and contribute ten times more carbon dioxide to the atmosphere each year than the burning of fossil fuels. This study provides new insight on the factors driving soil respiration at the global scale by assimilating satellite observations of soil moisture, temperature, and net primary productivity with the Global Soil Respiration Database (SRDB).While temperature, moisture, carbon supply and other …
Human Consequences Of Climate Change, Climate Refugees: An Exploratory Essay, Frederick A. Snyder-Manetti
Human Consequences Of Climate Change, Climate Refugees: An Exploratory Essay, Frederick A. Snyder-Manetti
Graduate Student Theses, Dissertations, & Professional Papers
While planning my course schedule for the 2009 Spring Semester, I found myself desperately short of elective credits toward my Bachelor of Arts degree in Geography in order to graduate by the end of the 2010 Autumn Semester. From the limited course choices offered for the spring semester, only two worked with the other required courses I needed as well: Cultural & Global Competence and Global Hot Spots. Little did I know at the time, but the latter would prove to be the most stimulating course of my entire undergraduate geography program. Not only did this course forge within me …
Community Perturbation Associated With New Zealand Mudsnail (Potamapyrgus Antipodarum) Invasion: Discrepancies In Temporal And Spatial Assessment, Eric H. Richins
Community Perturbation Associated With New Zealand Mudsnail (Potamapyrgus Antipodarum) Invasion: Discrepancies In Temporal And Spatial Assessment, Eric H. Richins
Graduate Student Theses, Dissertations, & Professional Papers
Invasive species have the potential to alter the ecosystems within which they establish as well as adjacent but uninvaded ecosystems by altering the flow of nutrients or biota across system boundaries. New Zealand mudsnails (Potamopyrgus antipodarum; NZMS) are often very abundant where they invade, sequestering the majority of stream primary production. This sequestering of production may reduce aquatic insect production, subsequent insect emergence and subsidies to riparian ecosystems. Tetragnathid spiders, an insectivorous riparian specialist, are dependent on the emergence of aquatic insects and are typical indicators of aquatic insect subsidies to riparian zones. In addition, NZMS invasions can result …

Proterozoic Tectonometamorphic Evolution Of The Ruby Range, Sw Montana, Usa: Insights From Phase Equilibria Modeling And In Situ Monazite Petrochronology, Martin Cramer
Graduate Student Theses, Dissertations, & Professional Papers
Phase equilibria modeling and monazite petrochronology reveal a complex history for the Ruby Range, SW Montana, which provides insights into the reactivation and growth of the northwestern Wyoming craton. Metapelites and orthoamphibolites from three areas were investigated. Stone Creek, the structurally highest area along the western flank, records a clockwise P–T path with peak conditions of ~6.5 kbar and ~760 °C and post-peak conditions of ~6.0 kbar and ~680 °C. Monazite growth in this area occurred at 1790–1723 Ma, with monazite inclusions in garnet at 1757 ± 8 Ma. Structurally deeper rocks at Elk Gulch in the south-central part …

Classroom Modifications With Improved Acoustics Modeled For Cehic, A School For The Deaf, In Kelaniya, Sri Lanka, Polwatte Krishantha Silva
Graduate Student Theses, Dissertations, & Professional Papers
The purpose of this study was to model a typical classroom in a school for the Deaf inKelaniya,Sri Lanka. Intense effort by teachers provides intervention for students with significant hearing impairment. The school is an oral school, and the philosophy is to utilize the residual hearing of each student through the use of high-powered hearing aids. Like many schools inSri Lanka, the Centre for Education of Hearing-Impaired Children (CEHIC) has many classrooms that have both high ambient noise with long reverberation times. Both noise and reverberation interfere with the sound signal, the teacher’s voice, and provide a poor learning environment …
Speaking For You: Positions Of Montana Ranching Organizations On Beef Market Concentration, Katie Marie Leblanc
Speaking For You: Positions Of Montana Ranching Organizations On Beef Market Concentration, Katie Marie Leblanc
Graduate Student Theses, Dissertations, & Professional Papers
Beef market concentration continues to be a highly contentious issue; especially in the culture-‐rich ranching industry of Montana. The agriculture industry, specifically the beef sector, has experienced a tremendous amount of integration and consolidation over the past 50 years. This amount of industry restructuring has crafted a beef backgrounding and processing sector with the highest rates of concentration ever witnessed, with a Concentration Ratio (CR4) reaching nearly 82%. This research aims to qualitatively investigate ranching organizational positions, on the topic of beef market concentration and potential impacts this has had on the organization and their members who are located and …
Capturing The Benefits Of Restoration: Local Business Utilization And Opportunities For Growth In Northwestern Montana, Chelsea P. Mciver
Capturing The Benefits Of Restoration: Local Business Utilization And Opportunities For Growth In Northwestern Montana, Chelsea P. Mciver
Graduate Student Theses, Dissertations, & Professional Papers
Restoration and maintenance of forests and watersheds is increasingly a focus of management on public lands and, in addition to traditional forest management activities, has the potential to contribute to the economic vitality of local, forest-dependent communities. However, research has shown that the extent to which local communities benefit from restoration and management activities is highly variable. This study seeks to understand whether local communities in northwestern Montana are capturing the benefits of these activities on public lands by analyzing federal contracting trends. Specifically, this study 1) characterizes the value and type of federal contracts along with the spatial distribution …
Cows And Plows: Science-Based Conservation For Grassland Songbirds In Agricultural Landscapes, Marisa K. Lipsey
Cows And Plows: Science-Based Conservation For Grassland Songbirds In Agricultural Landscapes, Marisa K. Lipsey
Graduate Student Theses, Dissertations, & Professional Papers
Temperate grasslands are among earth’s most imperiled ecosystems. In North America, steep declines of endemic songbird populations indicate that grassland loss and degradation may be approaching critical levels. Grasslands are agricultural landscapes largely (~85%) under private ownership with little formal protection status. Remaining bird populations depend on grazing lands that have not been converted to cropland. We combine regional data from a hotspot for grassland bird diversity (northeast Montana, USA; 26,500-km2) with continental data spanning the northern Great Plains (1,000,000-km2) to evaluate how land use and management influence bird distribution and abundance. Regionally, habitat used by seven grassland specialists spanned …
The Habitat Of European Brown Bears In Northern Spain: Mapping Habitat Fragmentation And Potential Connectivity, Alma D. Pacheco
The Habitat Of European Brown Bears In Northern Spain: Mapping Habitat Fragmentation And Potential Connectivity, Alma D. Pacheco
Graduate Student Theses, Dissertations, & Professional Papers
The European brown bear in northern Spain is considered to be an endangered species whose habitat has been fragmented into two subpopulations due to habitat loss and lack of connectivity. The importance of improving connectivity and preventing more habitat destruction is vital to recover the species in this region. This research looks at spatial and temporal variations of brown bear habitat by mapping the conditions of habitat fragmentation and potential connectivity at a regional extent. This research examines net changes of brown bear habitat fragmentation between 1990-2000, 2000-2006, and overall 1990-2006; and the degree of brown bear habitat connectivity between …
A Model For Determining Drivers Of Phenology In Western United States Rangelands, Joseph R. St. Peter
A Model For Determining Drivers Of Phenology In Western United States Rangelands, Joseph R. St. Peter
Graduate Student Theses, Dissertations, & Professional Papers
Plant phenology has long been used as an indicator of climate. Recent changes in plant phenology are evidence of the influence of climate change. Modeling plant phenology has become an effective tool to understand the impacts of climate change. Using machine learning techniques I developed a modeling process for accurately predicting phenology across a diverse landscape. This model uses individual site data to set site specific climate thresholds for plant phenology. This model also identifies the limiting factors to vegetation phenology for rangelands in the western United States. NDVI remotely sensed data was used to quantify land surface phenology and …

Within minutes after emission, rapid, complex photochemistry within a biomass burning smoke plume can cause large changes in the concentrations of ozone (O3) and organic aerosol (OA). Being able to understand and simulate this rapid chemical evolution under a wide variety of conditions is a critical part of forecasting the impact of these fires on air quality, atmospheric composition, and climate. Here we use version 2.1 of the Aerosol Simulation Program (ASP) to simulate the evolution of O3 and secondary organic aerosol (SOA) within a young biomass burning smoke plume from the Williams prescribed burn in chaparral, …

The Interstellar Boundary Explorer (IBEX) mission continues to measure energetic neutral atom (ENA) emissions produced by charge exchange between solar wind (SW) protons and interstellar neutrals at the edge of our heliosphere. Using the first 3 yr of IBEX-Hi ENA measurements (2009-2011), we examined the spectral evolution of ~0.5-6 keV ENAs at the polar regions (above 60°). We found the following: (1) pixels with a characteristic "ankle" spectra (lower spectral index at higher energies) increase by ~5% in 2010 and ~10% in 2011 compared to 2009. (2) The averaged spectral index in 2011 is smaller than that of 2009. (3) …
Flow Dynamics Of Byrd Glacier, East Antarctica, C. J. Van Der Veen, L. A. Stearns, Jesse Johnson, B. Csatho
Flow Dynamics Of Byrd Glacier, East Antarctica, C. J. Van Der Veen, L. A. Stearns, Jesse Johnson, B. Csatho
Computer Science Faculty Publications
Force-balance calculations on Byrd Glacier, East Antarctica, reveal large spatial variations in the along-flow component of driving stress with corresponding sticky spots that are stationary over time. On the large scale, flow resistance is partitioned between basal (�80%) and lateral (�20%) drag. Ice flow is due mostly to basal sliding and concentrated vertical shear in the basal ice layers, indicating the bed is at or close to the pressure-melting temperature. There is a significant component of driving stress in the across-flow direction resulting in nonzero basal drag in that direction. This is an unrealistic result and we propose that there …
Bhaskara’S Approximation For The Sine, Karel Stroethoff
Bhaskara’S Approximation For The Sine, Karel Stroethoff
The Mathematics Enthusiast
The 7th century Indian mathematician Bhaskara (c.600 – c.680) obtained a remarkable approximation for the sine function. Many subsequent ancient authors have given versions of this rule, but none provided a proof or described how the result was obtained. Grover [1] provides a possible explanation, but I think the rule can be explained more clearly. Rather than give the rule first, we will derive it, and then discuss its accuracy, and explore some alternative approximations. Our derivation is simply an exercise in modeling.

Numerically Integrating Irregularly-Spaced (X, Y) Data, B. Cameron Reed
The Mathematics Enthusiast
This article describes a computer program for numerically integrating under a y(x) curve of experimental data where the abscissa values are not equally-spaced. This technique is based on fitting parabolas to successive groups of three data points, and may be regarded as a generalization of Simpson’s rule.
Math As A Tool Of Anti-Semitism, Jay Egenhoff
Math As A Tool Of Anti-Semitism, Jay Egenhoff
The Mathematics Enthusiast
At Moscow State University’s Department of Mathematics during the 1970’s and 1980’s, there was rampant discrimination against Jewish and other unwanted students. The professors at the math department made a strong effort to keep Jewish students out of the department. They designed "killer" or "coffin" problems and Jewish students had to answer them during an oral exam. These problems have simple solutions, but require a clever strategy to solve them. This paper explores some of the context of this episode and provides several problems with detailed solutions.
An Examination Of Pre-Service Secondary Mathematics Teachers’ Conceptions Of Angles, Melike Yigit
An Examination Of Pre-Service Secondary Mathematics Teachers’ Conceptions Of Angles, Melike Yigit
The Mathematics Enthusiast
The concept of angles is one of the foundational concepts to develop of geometric knowledge, but it remains a difficult concept for students and teachers to grasp. Exiting studies claimed that students’ difficulties in learning of the concept of angles are based on learning of the multiple definitions of an angle, describing angles measuring the size of angles, and conceiving different types of angles such as 0-line angles, 1- line angles, and 2-line angles. This study was designed to gain better insight into pre-service secondary mathematics teachers’ (PSMTs) mental constructions of the concept of angles from the perspective of Action-Process-Object-Schema …
Common Sense About The Common Core, Alan H. Schoenfeld
Common Sense About The Common Core, Alan H. Schoenfeld
The Mathematics Enthusiast
Is the Common Core the best thing since sliced bread, or the work of the devil? Is it brand new, or a rehash of old ideas? Is it anything more than a brand name, or is there substance? Can it work, given the implementation challenges in our political and school systems? Opinions about the Common Core are everywhere, but the op-eds I’ve seen are often short on facts, and equally short on common sense. A mathematician by training, I’ve worked for nearly 40 years as an education researcher, curriculum materials developer, test developer, standards writer, and teacher. What follows is …
Book Review Of The Tower Of Hanoi: Myths And Maths (Birkhäuser), Cory Palmer
Book Review Of The Tower Of Hanoi: Myths And Maths (Birkhäuser), Cory Palmer
The Mathematics Enthusiast
As the title of the book suggests, the central topic of “The Tower of Hanoi – Myths and Maths” by Hinz, Klavˇzar, Milutinovi´c, and Petr is the famous puzzle of the same name. The classic Tower of Hanoi puzzle along with a number of its variations and related puzzles are examined in a rigorous mathematical framework.
