Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Great Plains social-ecological systems are facing growing pressure from complex, ‘wicked’ problems. Addressing these problems will require integrating ecological resilience and complex systems thinking concepts into our legal framework in order to better reflect the changing ecological reality of the Great Plains and promote flexibility and adaptability in the face of that change. In this dissertation, I examine how past and present policy priorities have affected social-ecological systems on the Great Plains, and how ecological resilience and complex systems thinking might be applied to grassland management policy. In Chapter 2, I examine the rapid progress made in the adoption of …

Further Developing Drought Early Warning Information Systems Using Mixed-Methods And Multiple Streams Of Data, Caily Claire Schwartz

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Drought is a complex phenomenon with varying degrees of impacts and monitoring methods. No drought is alike, creating a challenge for both water managers and communities. No area is immune to a drought. Due to the cyclical nature of drought events, clear information to those impacted is necessary to reduce risk and move towards proactive responses, as opposed to reactive responses. To better provide communication and mitigation tools, Drought Early Warning Information Systems (DEWIS) have been developed in various regions and contexts. To improve early warning, an understanding of the end user’s perceptions of risk, and the applicability of data …

Applying Circuit Theory To Describe Changes In Structural Landscape Connectivity In Response To Wildfire, Christian Ross Nielsen

School of Natural Resources: Dissertations, Theses, and Student Research

Understanding and conserving ecological connectivity is critical to the preservation of vulnerable landscapes. Circuit theory, in which landscapes are imagined as circuit boards with varying resistances to the flow of current, is being increasingly used to model spatially explicit connectivity of landscapes and to inform land management and conservation decision-making. Utilizing continuous, quantitative estimates of percent cover by five land cover functional groups to create a conductance surface, this study expanded upon an established application of circuit theory that used the open-source software Circuitscape to model species-agnostic, omnidirectional connectivity. This model was automated using Python to create time-series connectivity maps …

School of Natural Resources: Dissertations, Theses, and Student Research

Cyanobacterial harmful algal blooms (CyanoHABs) detrimentally affect human, animal, and ecosystem health. Remotely sensed early warning systems for cyanoHABs in inland lakes could contribute to more proactive water quality monitoring and help mitigate negative impacts. Advances in freely available remote sensing imagery, with finer spatial, temporal, and spectral resolutions, present new opportunities for the development and comparative analysis of methods to detect sudden deterioration in lake water quality. In this thesis, I compared and tested for temporal and spatial early warning signals of cyanoHABs in field-based and remotely sensed datasets from 2019 to 2023 in Pawnee Lake in southeast Nebraska, …

Assessing, Restoring, And Centering Social–Ecological Relationships For Advancing Social–Ecological Resilience In The Northern Great Plains Grasslands, Katia Pilar Carranza Bernal

School of Natural Resources: Dissertations, Theses, and Student Research

The Northern Great Plains grasslands are social-ecological systems that were shaped by evolutionary and Indigenous social-ecological relationships. European colonization disrupted many of these interactions, including the coupling of fire and grazing, and degraded social-ecological resilience, shifting these grasslands to a new state. For those reasons, my research focused on assessing, restoring, and centering evolutionary and Indigenous social-ecological relationships for advancing social-ecological resilience in the Northern Great Plains grasslands. I first performed a study in the Nebraska Sandhillls assessing the potential of patch-burn grazing to support grassland resilience by comparing its effects to those of rotational grazing. Through vegetation and bird …

The Role Of 5-Ht6 Receptor Activation In Learning Consolidation, Jasmine Alyssa Robinson

Electronic Theses, Projects, and Dissertations

The focus on serotonergic dysfunction as a contributor to cognitive deficits in disorders such as autism spectrum disorder, Alzheimer's disease, and schizophrenia drives researchers to investigate the functional impact of specific serotonin receptor types on executive functioning. By discerning the potential enhancement or impairment effects, this endeavor seeks to unravel the complex interplay between serotonin receptors and cognitive abilities. Specifically, within the three domains of learning, acquisition, consolidation, and retrieval, we find serotonergic modulation to be pivotal. Recent studies have highlighted the 5-HT6 receptor as a novel target for cognitive enhancement. However, the majority of the research investigates the effects …

Making Waves In The Snow World: Microwave Remote Sensing And Infrasound Interactions With Seasonal Snow, Zachary Marshall Hoppinen

Boise State University Theses and Dissertations

Snow has profound impacts on our globe, economies, and ecosystems serving as a vital reservoir for drinking and irrigation water, renewable hydroelectric power, and as a natural hazard. However, effectively monitoring snow and snow water equivalent (SWE) presents challenges due to interannual variability, with SWE fluctuating by over 500 mm between years and peak snowmelt timing varying up to a month. These challenges will be further exacerbated by the non-stationarity of these snow and avalanche patterns in a changing climate requiring new spatially and temporally expansive remote sensing.

In this dissertation, we explore the potential of two evolving remote sensing …

On An Unshakeable Foundation: An Archaeological Investigation Of The Postemancipation Black Community Of Bass Street, The Church They Built, And The Lasting Identity They Formed In Nashville, Tennessee, Clélie Elizabeth Cottle Peacock

Master's Theses

The Bass Street Community lived along the northern base of St. Cloud Hill in Nashville, just below the Civil War-era Union fortification, Fort Negley. The fort was built and defended by conscripted free, enslaved, and self-emancipated Black/African Americans and soldiers from the U.S. Colored Troops; some of whom stayed, built residences, founded a church, and established a shared community identity. The objects they left behind reflect a time of transition in the postemancipation urban South.

The former Bass Street Community enclave is a subset of the Fort Negley archaeological site (40DV189). My thesis examines artifacts from the Bass Street Baptist …

Remembering, Forgetting, And Artifact Deposition In Late Prehistoric Florida, Andrew Bowen

Master's Theses

Material culture plays a fundamental role in memory processes. Artifacts are an important means of both connecting with and cutting ties with a real or imagined past. They can be reminders or symbols of connection to other people, places, things, powers, or memories, making them key components within networks and relations. The way materials are deposited or destroyed often follows specific customs or responds to environmental factors. Specific situations, like interactions with outside groups or socio-political changes, prompt particular depositional events. During the Mississippi period, such circumstances were prevalent throughout the Southeast. By treating artifacts in specific ways during deposition, …

Linking Risk Preference, Women’S Empowerment, Farm Investment And Household Well-Being, Samuel Olusesi Olumide

Department of Agricultural Economics: Dissertations, Theses, and Student Research

A nuanced understanding of intra-household dynamics can inform the design of more effective empowerment and agricultural investment policies. By integrating household risk preferences and empowerment dynamics, this work offers valuable insights into the complex mechanisms driving household welfare and provides a framework for future interventions to promote gender equality and economic development in rural settings. This thesis addresses three core hypotheses: first, that the spouses of risk-seeking male heads are more likely to be disempowered compared to those of risk-averse male heads; second, that households with risk-seeking male heads and disempowered spouses are likely to invest more in farming activities; …

Contributing Factors That Affect The Perception Of Canis Lupus, The Grey Wolf, In Idaho, Karl Michael Prokop

Boise State University Theses and Dissertations

Human-wildlife coexistence has become a hot topic of late, especially in the case of the grey wolf, where there are generally two distinct camps; those that strongly support wolf conservation and those that strongly support wolf eradication. This research explores the factors influencing a person’s perception of the wolf. Some previous research suggests that formal education may be one important factor, where more formal education leads to more positive perceptions of the wolf. Other factors, such as geographic location (e.g., urban versus rural), have also been proposed as important contributors to wolf perception. While studies of these factors have been …

High Fat Diet & Social Isolation: Interactive Effects On Pain, Cognition, & Neuroinflammation, Ian M. Campuzano

Research Psychology Theses

Prior research has established a role for both social isolation and exposure to high fat Western diets in altering a range of behaviors from reduced memory performance to increased depression-like behaviors. The present study scrutinizes the interplay among these variables during the peri-adolescent developmental phase, utilizing Long-Evans rats as the experimental model. Our overarching hypothesis is that rats exposed to either social isolation, a high-fat diet, or both will result in heightened pain sensitivity, diminished cognitive flexibility, and increased neuroinflammatory responses within brain regions implicated in sociability, cognition, memory, and pain processing. Behavioral flexibility will be assessed using a maze-based …

Social Support In The Time Of Social Media: Predicting Gen Zers’ Preferences For In-Person And Virtual Support, Carla Mastroianni

Seton Hall University Dissertations and Theses (ETDs)

Increased usage of social networking sites (SNS) among young people, both before and during the COVID-19 pandemic, is well documented. Both positive and negative associations with SNS usage have been found. However, findings lack causal links and describe frequency of usage, applications used, and generalized descriptions of usage type (e.g., to connect with others versus consume content). There is considerable movement toward understanding SNS usage type and trends by subgroup—a precursor to better understanding which groups are using SNS for what purposes, particularly those more likely to experience negative outcomes associated with SNS. This study utilized a cross-sectional design to …

To Pot Or Not To Pot: Understanding Technological Investment In Ceramics And Marine Mammal Oil Rendering In Kodiak, Alaska, Elizabeth Groat

All Graduate Theses and Dissertations, Fall 2023 to Present

Why do groups choose to use certain technologies, but not others? This study focuses on an especially confusing instance of this question: the adoption of pottery in Kodiak, Alaska. This event was strange for two reasons. First, by AD 1500, when Alutiiq ancestors in the Kodiak Archipelago began making pottery, their neighbors on the mainland had already been doing it for centuries—so why did they wait so long? Second, pottery is also only found in the south of the islands—so why did some people use it, but not others? Whale and seal are more abundant in southern Kodiak, so one …

Contrasting Management Styles And Differing Outcomes Of Capping And Orphaning Of Utah Oil And Gas Wells By Conditions And Land Types, Maxwell C. Parson

All Graduate Theses and Dissertations, Fall 2023 to Present

The issue of public lands management and ownership in the West has long been contentious. This thesis takes a quantitative approach examining outcomes of the rates at which oil and gas wells in the state of Utah are orphaned and/or capped. Findings indicate that orphanings occur at a statistically significant higher rate on state owned land as opposed to federal and private, and wells on tribal land have no recorded orphaning. No other variables were significant in their relationship to orphaning. The proposed explanations for this disparity are two-fold: First the longer periods of inactivity permitted by the state simply …

Gpr171 Modulates Mood, Consummatory Behaviors, And Morphine Antinociception In A Sexually Dimorphic Pattern In Mice, Megan C. Raddatz

All Graduate Theses and Dissertations, Fall 2023 to Present

Receptors in the brain influence everything from complex behaviors related to mood, all the way to simple physiological functions like the way a person moves. Receptors are activated or inactivated by chemicals or hormones that the body produces or that are created to mimic the body’s natural chemicals. Of the hundreds of receptors in the brain, GPR171 is particularly interesting because new drugs have been created to activate or block the receptor, and are being proposed for the treatment of different disorders, particularly disorders related to pain. GPR171 has been shown to affect pain behaviors, eating, and mood-related behaviors, but …

Healing Through Caring And Knowledge-Making In Everyday Food Practices Among Lgbtq+ Black, Indigenous, People Of Colour, Elizabeth Grace Wong

All Graduate Theses and Dissertations, Fall 2023 to Present

Three different models are used in this study to understand how everyday food practices carry healing potential through the interwoven process of caring and knowledge-making. Daily food practices reflect a mixture of tradition and modernity— borne out of our roots and our contexts. Anzaldúa’s (1987) Borderland Theory helps us understand how this mixture is made by people who straddle two borders or worlds and contest those confines. Chavez-Dueñas et al.’s (2019) HEART model names strengthening our cultural and familial traditions and roots as part of the broader processes of building cultural consciousness and connection, and engaging in collective healing. Finally, …
