Classifying The 2022 Status Of Tsuga Canadensis (Eastern Hemlock) Along The Kentucky Portion Of The Pine Mountain Wildlands Corridor., Grace M. Embree

Electronic Theses and Dissertations

The invasion of the Hemlock Woolly Adelgid (HWA) (Adelges tsugae) has posed a continual threat in the United States to the Eastern Hemlock (Tsuga canadensis) trees since the 1950s. HWA feed on eastern hemlock needles, reducing the amount of healthy photosynthesizing vegetative area. The use of satellite imagery has been instrumental in identifying areas of eastern hemlock presence. Satellite platforms like Landsat and AVIRIS are commonly used for identification, classification, and mapping of eastern hemlock. Sentinel-2 imagery was released in 2015 for free access. It has a finer spatial grain of with the majority of the …

Vietnam Continued: The Battle For American Public Memory In Public School History Textbooks, Donnie Owens

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The question of “how do we actively remember the past?” can perhaps best describe the purpose of public memory studies. Acknowledging this question, I analyze popular public-school textbooks to assess the way in which educational literature constructs the public memory of the Vietnam War. In total, the narratives of the texts construct a public memory of Vietnam as a controversial conflict contained within a decade of American uncertainty. However, these narratives also take care to minimize or leave aside the details of Vietnam’s lasting impact and in favor of reaffirming American exceptionalism. Ultimately, this thesis finds that students who read …

Teaching Multicultural Psychology As A Cultural Competence Intervention: An Empirical Evaluation Of Course Components, Elizabeth Tish Hicks

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Previous research has shown that a semester-long multicultural psychology course can effectively increase students’ cultural competence-related attitudes when students complete the class in-person and online. Cultural competence refers to the knowledge, awareness, and skills required to appreciate, recognize, and effectively work with members of other cultural groups. This dissertation examined several components of a multicultural psychology course: ethical grading, skill development, and intergroup contact. The first paper discussed techniques used to minimize grading bias and examined whether cultural competence shifts impacted grading. Students’ cultural competence scores did not relate to or predict their grades in the course, which supported the …

The Effect Of Congressional Committee Assignments On National Park Annual Operating Budget Appropriations, Braden T. Morrill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Yearly funding for individual national parks is overseen and determined by the House Appropriations and Natural Resources Committees. This process has resulted in the National Park Service being underfunded and facing a $12 billion maintenance backlog. Congress has passed temporary funding to help reduce this backlog but has not indicated a shift in how funding decisions are made to prevent future shortfalls.

This thesis uses statistical analysis to explore how individual members of Congress are impacting funding for national Parks in their states or districts. Often congressional committee’s act on personal incentives to make funding decisions rather than basing their …

Conservation Conflict: Rare Plant Conservation And Energy Development And Potential In The Colorado Plateau, Joshua Carrell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Colorado Plateau provides numerous sources of energy, particularly natural oil and gas. This energy potential is being actively extracted for consumption on both public and private lands. Elements of biodiversity (e.g., listed and sensitive plant and animal species) are distributed among all land tenures, yet the laws protecting them can vary depending if they occur on public, private, or tribal land. Therefore, it is necessary to understand the geographic ranges of threatened, endangered, and sensitive species and their relationship to land ownership to preserve habitat and conserve species populations. I developed species distribution models (SDMs) to examine the predicted …

An Evaluation Of Landscape, Climate, And Management Impacts On Bumble Bees (Hymenoptera: Apidae: Bombus) In Agroecosystems, Morgan Elizabeth Christman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Bumble bees play pivotal roles in pollinating wild and cultivated plant communities. Unfortunately, bumble bee populations are declining due to disturbances such as landscape conversion and climate change. Additionally, traps used to monitor pest insect populations often capture bumble bees, leading to a concern that trap captures increase bumble bee mortality. First, I studied bumble bee communities based on land cover and weather variables in agricultural fields in Utah. Bumble bee communities were more diverse in agricultural fields with more agricultural land in the surrounding area, low temperatures, and high humidity during the growing season, and less diverse in fields …

Sustain Water Conservation Behaviors Using Nonparametric Ranking And Social Marketing, Mahmudur Rahman Aveek

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Circulation of water use feedback and conservation messaging are strategies implemented to reduce water demand on a short-term (seasonal) basis. Often considered a less impactful strategy than other tactics such as price increments and usage restrictions, authorities mostly use feedback in informational campaigns with a focus to apprise users about their water use. Such conservation programs have had limited success that has been attributed to the fact that the information provided with the feedback campaigns was generic and did not motivate users enough to sustain their water-saving behaviors. However, the advent of disaggregation technologies that can provide appliance-wise water use …

The Rio Virgin: A Turbulent River, Mormon Pioneers, And The Creation Of A Landscape 1854-1921, Spencer Wayne Mcconkie

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis explores the changes to the landscape of the Virgin River Basin by Mormon pioneers and the environment between 1854 and 1921. This thesis shows the ways in which the Mormons replaced the local vegetation of the basin with new crops and expanded the area available for farming through the use of irrigation canals and different farming techniques. Along with showing the ways in which the Mormons changed the landscape the thesis explores the ways in which environmental changes played into this process. The process of creating the new landscape of the Virgin River Basin involved both natural and …

The Working Man's Rendezvous, Tameron Gentry Raines Williams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The mountain men—fur traders of the Rocky Mountain trade between 1822-1840—are prominent in the history of the American West. Their adventures and exploits have been told and retold as their legend grew as did the myth surrounding their lives. This thesis seeks to dismantle that myth through focused study on the conditions of fur trapping work, the interactions between mountain men and Indigenous tribes of the region, and the role of lesser-known Black fur trappers.

Conservation Genetics Of A Declining Bumble Bee In Western North America; The Influence Of Geography, Dispersal Limitation, And Anthopogenic Activity, Ashley T. Rohde

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Conservation biology addresses the problem of species loss by identifying species in need of protection. Conservation biology has subfields to address different aspects of biodiversity loss, including genetics and sociology. I used genetic approaches to assess the conservation status of western bumble bees, a bumble bee species of conservation concern.

The western bumble bee is a bumble bee species that ranges from Alaska to New Mexico and as far east as Wyoming and Colorado. This species is disappearing in some places. It may soon be listed as endangered in the United States and is already listed as endangered in parts …

Development Of Late-Heading Orchardgrass Germplasm, Megan Marie Getz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dactylis glomerata L., orchardgrass, is commonly grown with perennial forages such as alfalfa (Medicago sativa L.). However, commercial orchardgrass cultivars currently grown in the Intermountain West generally flower earlier than alfalfa. This results in a reduction in grass nutritional value if harvested to maximize the alfalfa yield, because the two species mature at different rates. Thus, there is a need to better understand the genetic basis of flowering time in orchardgrass and develop late-flowering populations. The objectives of this research were to evaluate the ability to identify and use molecular markers to identify and select late-heading orchardgrass; and to …

Reversing The Gaze: Using Indigenous And Western Worldviews To Compare Coverage Of Climate Change And Indigenous Peoples In The News Media, Gina Mccrackin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The news media acts as an important conduit for shaping societal views of the socio-politics of climate change. While climate change will indeed affect everyone, it will not affect everyone equally. Indigenous peoples are among the populations whose well-being is threatened the most by climate change. International scholarship finds it is not uncommon for Indigenous cultures, communities, and perspectives to be underrepresented and misrepresented in Western climate change media. Research also indicates that fair Indigenous representation occurs when Indigenous peoples are the authors of news articles themselves. We evaluated the differences in discussions of climate change and environmental issues …

Ecological Differences In The Associations Between Air Pollution, Greenness, And Risk Of Stroke: The Regards Study., Daniel W. Riggs

Electronic Theses and Dissertations

The adverse health effects of air pollution have long been recognized, with the majority of morbidity and mortality due to its effects on the cardiovascular system. Alternatively, living in areas with higher greenness has been found to be beneficial to a wide range of health outcomes. However, few studies have considered that these relationships may vary depending on the surrounding ecosystem. The purpose of this dissertation was to examine the effects of long-term exposure to air pollution and greenness on incidence of stroke, and how these relationships vary with the major ecological regions of the United States. We utilized the …

Forest Carbon Incentive Programs For Non-Industrial Private Forests In Oregon (Usa): Impacts Of Program Design On Willingness To Enroll And Landscape-Scale Program Outcomes, Rose A. Graves, Max Nielsen-Pincus, Ryan D. Haugo, Andres Holz

Environmental Science and Management Faculty Publications and Presentations

Privately-owned forests in the Pacific Northwest (PNW) are important potential carbon sinks and play a large role in carbon sequestration and storage. Non-industrial private forest (NIPF) owners constitute a substantial portion of overall forest landownership in productive regions of the PNW; however, little is known about their preferences for non-market incentive programs aimed at increased carbon storage and sequestration, specifically by limiting timber harvest, and how those preferences might impact the outcome of forest carbon programs. We simulated landscape-scale outcomes of hypothetical forest carbon incentive programs in western Oregon (USA) by combining empirical models of NIPF owners' participation with spatially …

Piloting An Index Of Segregation At The Census Tract Level: Associations With Place And Racial/Ethnic Disparities In Life Expectancies, Katherine F. Kitchens

Social Work Theses - Archive

This study considers residential segregation as a critical driver of racial/ethnic health disparities and introduces an index of segregation, the Representation Index, that measures segregation degree at the neighborhood level with a metric capturing the overrepresentation of a racialized/ethnic group in a census tract in relation to that group’s representation at the city level. Using Dallas, Texas as a pilot city, the index is used to investigate the association between Latinx, non-Hispanic white, non-Hispanic Black, and Asian-American groups’ over-representation at the neighborhood level with neighborhood rates of life expectancy at birth. This study aimed to expose the possibility of neighborhood …

Female Labor Force Participation And Intimate Partner Violence Among Married Women In Nepal, Nibedita Shrestha

Social Work Dissertations - Archive

Nepal has the highest rate of female labor force participation (FLFP) in South Asia (Ghosh, Singh, & Chigateri, 2017), alongside high levels of violence against women (Yoshikawa et al., 2014). The explanation for the co-occurrence of high levels of female labor force participation alongside significant amounts of intimate partner violence (IPV) has not been adequately explored. Studies on how the working status of a woman in Nepal makes her vulnerable to violence are few and far between (John, 2020). Theoretical models to account for this phenomenon are crucial to formulating interventions that are protective of working women. The current study …

Alfred Russel Wallace Notes 22: Stumbling Blocks To An Understanding Of Wallace's Worldview, Charles H. Smith

Faculty/Staff Personal Papers

The writings of Alfred Russel Wallace (1823−1913) present a challenge to modern readers, both for the large range of subjects he entertained, and his unique point of view. In this short treatment, ten ‘stumbling blocks’ to an appreciation of Wallace’s thought are outlined which, it is suggested, have caused problems of interpretation in the past.

Adventurers And Autocrats: The Role Of Authority In The Making Of The English West Indies, 1595-1655, John Clinton Harris

History Dissertations - Archive

After Walter Ralegh made his famous journey to the Orinoco in 1595, English adventurers began the haphazard process of colonizing the West Indies. Initially they tried to follow Ralegh’s efforts in Guiana, but their every effort failed because they lacked access to significant investment capital and did not enjoy the full backing of the crown. After several calamities, Englishmen interested in American colonization turned their efforts towards the Caribbean in 1623. Under the rule of Lord Proprietor James Hay, Earl of Carlisle, and his brutal governors English adventurers enjoyed more success. The key difference in Carlisle’s Caribbean and Ralegh’s Guiana …

Interpreting Sentinel-1 Sar Backscatter Signals Of Snowpack Surface Melt/Freeze, Warming, And Ripening, Through Field Measurements And Physically-Based Snowmodel, Jewell Lund, Richard R. Forster, Elias J. Deeb, Glen E. Liston, S. Mckenzie Skiles, Hans-Peter Marshall

Geosciences Faculty Publications and Presentations

The transition of a cold winter snowpack to one that is ripe and contributing to runoff is crucial to gauge for water resource management, but is highly variable in space and time. Snow surface melt/freeze cycles, associated with diurnal fluctuations in radiative inputs, are hallmarks of this transition. C-band synthetic aperture radar (SAR) reliably detects meltwater in the snowpack. Sentinel-1 (S1) C-band SAR offers consistent acquisition patterns that allow for diurnal investigations of melting snow. We used over 50 snow pit observations from 2020 in Grand Mesa, Colorado, USA, to track temperature and wetness in the snowpack as a function …

Modern Pyromes: Biogeographical Patterns Of Fire Characteristics Across The Contiguous United States, Megan E. Cattau, Adam Mahood, Jennifer K. Balch, Carol Wessman

Human-Environment Systems Research Center Faculty Publications and Presentations

In recent decades, wildfires in many areas of the United States (U.S.) have become larger and more frequent with increasing anthropogenic pressure, including interactions between climate, land-use change, and human ignitions. We aimed to characterize the spatiotemporal patterns of contemporary fire characteristics across the contiguous United States (CONUS). We derived fire variables based on frequency, fire radiative power (FRP), event size, burned area, and season length from satellite-derived fire products and a government records database on a 50 km grid (1984–2020). We used k-means clustering to create a hierarchical classification scheme of areas with relatively homogeneous fire characteristics, or modern …

Current Challenges In The Rio Grande/Río Bravo Basin: Old Disputes In A New Century, Regina M. Buono, Gabriel Eckstein

Faculty Scholarship

The Rio Grande River traverses 2000 kilometres of the international border between Mexico and the United States. The river and its tributaries are governed by a series of border treaties and institutions, as well as under the domestic laws of each nation. Often lauded for enabling innovative and collaborative governance, in recent years the complicated regime has come under pressure as domestic and international water governance institutions struggle under the strain of climate change, population growth, and other stressors on water supply and demand in the region. This chapter considers three of the major challenges currently facing the Rio Grande …

Treating Active-Duty Military Members: Best Practices For Common Mental Health Diagnoses Across The Dod, Leah Lawson

Electronic Theses and Dissertations

Due to varying service experiences, active-duty service members endure military related stressors in addition to everyday life stressors. As a result, their risk of mental illness onset increases. Considering that many of the stressors and events are unique to military personnel, it is important to identify best-practice interventions for working with this population opposed to employing civilian best practices. The purpose of this study was to determine what treatment interventions are best-practice when working with active-duty military members diagnosed with the three most common mental disorders (e.g., adjustment disorder, depressive disorders, anxiety disorders) across the Department of Defense (DoD). This …

Dissertations

This qualitative study employed educational criticism and connoisseurship to examine the curricular intentions of a school that was pushing to reform traditional standards-based curriculum methods. Improvement of the educational process required that focus be given to schools who had begun to do things differently, schools that had taken a risk to reform. This study examined a public school that holds innovation status. Data collection included interviews with the three founding teachers of the school and document analysis of a planning session transcript that included the school’s nine staff members. Additionally, data collection included document analysis of the founding teachers’ participation …

Data Fusion For Non-Motorized Volume Estimation: A Machine Learning Approach, Md. Mintu Miah

Civil Engineering Dissertations - Archive

ABSTRACT: Despite increased awareness at the state and federal levels of the design and policy concerns associated with nonmotorized infrastructure, communities typically develop strategies to estimate network-wide nonmotorized traffic. However, past research fails to provide the same level of estimation sophistication as motor vehicles due to a lack of investment, which limits increased understanding and capability among communities in network-wide nonmotorized traffic volume estimation. Although previous studies introduce machine learning, Neural Networks, and feature engineering to motorized traffic volume estimation, nonmotorized traffic estimation experiences limited attempts to use these advanced techniques. This dissertation addresses this deficiency in bicycle volume estimation …

Covid-19 And Traffic Safety: Exploring Exposure, Crash Frequency And Severity, And Roadway And Network Design, Nicholas N. Ferenchak Ph.D

Publications

Early COVID-19 lockdowns in the first half of 2020 largely kept people at home, thereby reducing motor vehicle traffic levels. Theoretically, reduced traffic exposure should have resulted in reduced motor vehicle crashes. However, a variety of factors may have complicated this relationship. In order to better understand the impact of COVID-19 lockdowns on traffic safety outcomes, we explore fatalities, injuries, and total crashes before and during the lockdowns on both the national and state levels. We provide descriptive statistics and create negative binomial regressions exploring the role of vehicle, user, and built environment factors on traffic safety outcomes. Findings suggest …

Architecture And Agency For Equity In Areas Beyond National Jurisdiction, Lisa M. Campbell, Robin Fail, Rebecca Horan, Leslie Acton, Jeffrey E. Blackwatters

Faculty Publications

The United Nations (UN) Sustainable Development Goals (SDGs) and the UN Decade of Ocean Science for Sustainable Development (Ocean Decade) bring increased attention to various aspects of ocean governance, including equity. One of the Ocean Decade's identified challenges is to develop a sustainable and equitable ocean economy, but questions arise about how to conceptualize the multiple dimensions of equity in an ocean context. These questions become more complex as activities move away from coastal ecosystems and communities into off-shore Areas Beyond National Jurisdiction (ABNJ), where ocean resources are recognized simultaneously as unowned/open access and as common heritage. In this paper, …
