Engineering Management & Systems Engineering Theses & Dissertations

This dissertation describes the use of Functional Dependency Network Analysis (FDNA) for modeling risks resulting from dependencies among elements of enterprise systems with application to salt processing enterprise in Ghana. FDNA was developed to model dependencies among members of enterprise systems by highlighting two dimensions of dependency: strength and criticality. Nonetheless, the concepts and analytics for these two dimensions of dependencies needed further development and generalization in the context of project management and systems development in developing countries.

Managing risks within the interdependency in enterprise systems through integration will help improve global economic growth. Coherent theory for enterprise integration must …

The Effects Of Urbanization On Avian Seed Dispersal Success Of Toxicodendron Radicans (Anacardiaceae), Aiden M. Stanley

Electronic Theses and Dissertations

Urbanization is increasing at a dramatic rate as the human population increases. While it is well-known that urbanization tends to decrease species diversity (i.e., biotic homogenization), it is not known how urbanization affects the frequency and efficiency of species interactions. Seed dispersal is a plant-animal interaction that depends on disperser feeding rate, disperser diversity, probability of seed dispersal and germination. How these factors are affected by urbanization however is unknown. In this study, we evaluate how urbanization alters these factors. Urban sites had 2x higher feeding rate and 3x higher number of disperser species. The probability of seed dispersal however …

By objectively quantifying infrastructure field inspections, inspectors can make more accurate field assessments and managers can make better-informed decisions. This project collaborated with stakeholders, national laboratories, DOT agencies such as NCHRP and …

From The Coils Of The Anaconda, Restriction Of Constitutional Amendment By Popular Initiative In Montana Association Of Counties V. State, Ryan Douglas

Montana Law Review

This note examines the ways in which Montana Association of Counties concerns Montana law, elections, and history. While it is now nearly futile to suggest any regulation of campaign speech based on the speaker's corporate identity, it is possible to limit the influence of outsiders on the political process and fundamental text of the state. Part II discusses the historical development of the statutory initiative and referendum regime that existed under the 1889 Constitution and tracks its transition to the constitutional amendment by popular initiative process that emerged as part of Montana's 1972 Constitution. Part III describes the factual background, …

Spatiotemporal Variability Of Twenty‐First‐Century Changes In Site‐Specific Snowfall Frequency Over The Northwest United States, Arielle J. Catalano, Paul C. Loikith, C. M. Aragon

Geography Faculty Publications and Presentations

In the Northwest United States, warming temperatures threaten mountain snowpacks. Reliable projections of snowfall changes are therefore critical to anticipate the timeline of change. However, producing such projections is challenging, as most state‐of‐the‐art climate models are limited in sufficiently resolving influential topography. Here we leverage atmospheric freezing level to estimate precipitation phase and project twenty‐first‐century snowfall frequency change at Snowpack Telemetry Network stations across the Northwest. Under “moderate” and “business‐as‐usual” emission pathways in Coupled Model Intercomparison Project phase 5 models, snowfall frequency is projected to decline at all stations. Business‐as‐usual declines accelerate after midcentury at most locations, whereas moderate declines …

Dynamics Of Land Use, Environment, And Social Organization In The Sasanian Landscape Of Eastern Iraq—Western Iran, Mitra Panahipour

Graduate Theses and Dissertations

Understanding human-environment interactions has been one of the main challenges in archaeological studies over recent years. Past research on the Near Eastern territorial empires in general, and the Sasanian Empire in particular, primarily emphasized the dominant role of human on landscape transformation. In addition, politically centralized schemes such as agricultural intensification and expansion of water supply systems have been at the center of most of the discussions and remained the main hypothesis of the Sasanian land use practices.

This dissertation investigates population’s diverse responses to environmental variability during the Sasanian period (224-651 CE) across a landscape in eastern Iraq—western Iran. …

Response And Recovery Of Horn And Petit Bois Islands, Mississippi, Usa To Tropical Cyclone Impacts: 2004 – 2016, Shara Gremillion

Master's Theses

Horn and Petit Bois islands are two of five Mississippi (MS) barrier islands that provide physical protection from tropical cyclones threatening the MS Gulf Coast, in addition to critical habitat for the northern Gulf of Mexico (GOM). In September 2004, Hurricane Ivan removed a large volume of sediment from the eastern ends of Horn and Petit Bois islands with its 1-2 m storm surge and ~194 kph wind speeds. Then, in August 2005 Hurricane Katrina severely impacted the two islands again with its 3.5-5.5 m storm surge on Horn and Petit Bois islands, and up to 204 kph wind speeds …

Adapting Environmental Ethics And Behaviors: Toward A Posthuman Rhetoric Of Community Engagement, Beth J. Shirley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

What persuades people one way or another to accept or deny climate change? More importantly, what persuades people to act on, ignore, or even be defiant of climate change? We would like to think that people are motivated when they hear the science explained clearly and when they are presented with a clear understanding of how their actions have a lasting impact. Yet the science on climate change has been made clear for some time, and doubt in climate change science is rampant (at least in the United States).

This dissertation seeks to answer these questions and develop a new …

How Virtual Reality Impacts The Landscape Architecture Design Process At Various Scales, Drew M. Hill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the field of landscape architecture, the use of virtual reality (VR) is increasing as a tool for visualization and presentation in the late stages of the design process. Many of the benefits that make VR valuable in the later stages of the design process suggest that VR may also be valuable when used in earlier stages such as analysis and concept development. However, existing research does not provide a detailed study of design within VR during those early stages. Recent advancements in technology allow the potential to bring significant changes in the way that design-related professionals collaborate and design. …

Urban Alaskan Moose: An Analysis Of Factors Associated With Moose-Vehicle Collisions, Lucian R. Mcdonald

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As human populations continue to grow and encroach into wildlife habitats, instances of human-wildlife conflict are on the rise. Increasing numbers of reported wildlife-vehicle collisions (WVCs) provide tangible evidence of anthropogenic impacts on wildlife as well as increasing threats to human health and safety. Increasing WVCs are of particular concern, especially those involving large-bodied ungulates such as moose (Alces spp.), because of the increased risk of property damage, personal injuries, and human fatalities. Motorists directly involved in a WVC are at risk of injury or mortality, but other motorists are also put at risk due to road obstructions and traffic …

The Influence Of Measurement Scale And Uncertainty On Interpretations Of River Migration, Mitchell R. Donovan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Environmental scientists increasingly use remotely-sensed images to measure how rivers develop over time and respond to upstream changes in environmental drivers such as land use, urbanization, deforestation and agricultural practices. These measurements are subject to uncertainty that can bias conclusions. The first step towards accurate interpretation of river channel change is properly quantifying and accounting for uncertainty involved in measuring changes in river morphology. In Chapter 2 we develop a comprehensive framework for quantifying uncertainty in measurements of river change derived from aerial images. The framework builds upon previous uncertainty research by describing best practices and context-specific strategies, comparing each …

Development And Validation Of An Agricultural Literacy Instrument Using The National Agricultural Literacy Outcomes, M. Rose Judd-Murray

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was conducted to develop a standardized agricultural literacy assessment using the National Agricultural Literacy Outcomes (NALOs) as benchmarks. The need for such an assessment was born out of previous research, which found that despite numerous programs dedicated to improving agricultural literacy, many students and adults remain at low or very low levels of literacy. Low literacy levels lead to negative associations with the production and processing of food, clothing, and shelter, as well as misinformed public perceptions and policies. Agricultural literacy researchers recognized that the development of a standardized assessment for post-12^th grade, or equivalent, could unify …

Interval-Valued Kriging Models With Applications In Design Ground Snow Load Prediction, Brennan L. Bean

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One critical consideration in the design of buildings constructed in the western United States is the weight of settled snow on the roof of the structure. Engineers are tasked with selecting a design snow load that ensures that the building is safe and reliable, without making the construction overly expensive. Western states use historical snow records at weather stations scattered throughout the region to estimate appropriate design snow loads. Various mapping techniques are then used to predict design snow loads between the weather stations. Each state uses different mapping techniques to create their snow load requirements, yet these different techniques …

The Vulnerability Of Littoral Structures Under Multiyear Drought Conditions, Jenna M. Keeton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Climate change is associated with altered environmental conditions and shifting mosaics of suitable habitats for organisms. Climate change in the form of drought can shift important lake shoreline habitats downslope, altering the lakes chemistry and habitat availability. Additionally, negative biological consequences can occur after a loss of submerged habitat along shorelines, hereafter littoral habitat. The objective of this study is to evaluate whether littoral habitat is lost (cobble, coarse woody habitat (fallen trees; CWH), and aquatic vegetation) under drought conditions across the United States. I used the National Lakes Assessment physical habitat data collected in summer 2012, when 75% of …

Trout Habitat In An Altered Gravel-Bed River With An Augmented Flow Regime, Jacob B. Stout

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Diamond Fork River, and it’s tributary Sixth Water Creek, has been highly altered in terms of shape, function, and ecologicaly due to large, trans-basin flows additions to the system for irrigation starting in the early 1900s. Flows were exceptionally large for 80 years, after which they were reduced in 2004. Larger than natural flows during the low flow season were then added to the river in an effort to improve ecosystem health and recreational fishing opportunities. Since the prescription additional flow during low flow seasons, the river channel has undergone further change, most noticeably in the form of narrowing. …

Ensuring A Holistic And Quality Education For Every Child: A Phenomenological Inquiry Of Principals’ Transformational Leadership, Elijah Granger

Electronic Theses and Dissertations

Researchers have not fully examined how school leaders impact the teaching and learning environment when working toward generating students’ academic success. Balyer (2012) called for more work on understanding the transformational leadership behaviors that create conditions conducive to generating student achievement within educational accountability. Therefore, the purpose of this phenomenological inquiry is to explore the lived experiences of principals and their perceptions concerning the state accountability system and how it may impact their transformational efforts in ensuring a holistic and quality education for every child. The phenomenological inquiry will yield the opportunity to compare administrators’ in-depth perceptions of the accountability …

Semantically Aligned Sentence-Level Embeddings For Agent Autonomy And Natural Language Understanding, Nancy Ellen Fulda

Theses and Dissertations

Many applications of neural linguistic models rely on their use as pre-trained features for downstream tasks such as dialog modeling, machine translation, and question answering. This work presents an alternate paradigm: Rather than treating linguistic embeddings as input features, we treat them as common sense knowledge repositories that can be queried using simple mathematical operations within the embedding space, without the need for additional training. Because current state-of-the-art embedding models were not optimized for this purpose, this work presents a novel embedding model designed and trained specifically for the purpose of "reasoning in the linguistic domain".Our model jointly represents single …

Experience Qualities Re-Examined: Improving The Measurement Of Experiential Conditions In Outdoor Recreation, Jessica Pearl Fefer

All Dissertations

Visitor use management (VUM) is the proactive and adaptive process for managing characteristics of visitor use and the natural and managerial setting using a variety of strategies and tools to achieve and maintain desired resource conditions and visitor experiences (IVUMC, 2018). For nearly 40 years, the application and operationalization of visitor use management has relied on a normative approach, which assumes that visitors to parks and recreation areas have shared attitudes and preferences about resource and social conditions. Visitor use management frameworks and the normative approach rely on defining management objectives, identifying indicators and thresholds for the visitor experience, monitoring …

Spirit Don't Ever Die: Apocalypse And Denial In An Infinite Universe, Nathan Riggs

Graduate Theses and Dissertations

In The Great Derangement, Amitav Ghosh catalogs contemporary fiction’s failure to adequately engage with catastrophic climate change. In this thesis, I argue the engagement problem has a century-old analogue in fiction’s approach to entropy. Entropy was among the first secular apocalyptic modes in mainstream discourse, and this investigation of authors’ approaches to its portrayal provides a model for understanding fiction’s denial or acceptance of apocalypse. I first examine William Hope Hodgson’s 1912 novel The Night Land, a far-future tale set in a post-solar Earth. I contend that Hodgson’s centering of the human experience prevents him from portraying a true end …

Communication Infrastructure Theory: A Rural Application, Callie S. Embry

Graduate Theses and Dissertations

The health of a community’s communication infrastructure influences their efficacy and efficiency in dealing with societal problems. The majority of previous communication infrastructure research has focused on multicultural urban centers. This study looks at the communication infrastructure of one rural Arkansas town, specifically looking for the places residents report as communication assets and the subjects discussed within the storytelling network. I used a combination of communication asset mapping and semi-structured interviews to identify the physical locations within the community where residents regularly converse with one another. The interviews along with observations also provided insight into the subject matter that residents …

The War On Winter: How Americans Put Down Roots On The Northern Plains, 1854-1949, Daniel J. Fischer

Graduate Theses and Dissertations

My dissertation is a study of how the United States was able to expand onto the Northern Great Plains, consisting of the Dakotas, Nebraska, and the eastern parts of Wyoming and Montana, between 1854 and 1949 despite the threat to property, comfort, and survival posed by the region’s harsh winters, which brought intense cold, large snowdrifts, and blinding blizzards. This dissertation argues that five tools – government programs, rapidly changing technology, imagination, strong local communities, and toughness – allowed native-born Americans and European immigrants to survive and become increasingly secure in the region. But it also argues that severe gaps …

Westward Empire: George Berkeley’S ‘Verses On The Prospect Of Planting Of Arts’ In American Art And Cultural History, Elizabeth Kiszonas

Graduate Theses and Dissertations

This study investigates the extraordinary half-life of a single line of poetry: “Westward the Course of Empire takes its Way…”. Beginning with their composition in 1726 by the Irish- Anglican bishop George Berkeley, these words colonized an enormous swath of cultural landscape over nearly two centuries. Immortalized in newsprint, broadsides, statesmen’s speeches, reading primers, geographies, the first scholarly history of the United States, as well as in poetry, paintings, lithographs, and photographs, the words evolved from an old-world vision of prophetic empire into a nationalist slogan of manifest destiny. Following the poem as it threads through literary and visual culture, …
