A Multi-Method Investigation Of Social Media Use In Adolescent Girls: Examining Emotion, Emotion Regulation, And Effects By Depression, Alison Tuck

Arts & Sciences Graduate Student Theses and Dissertations

Adolescents experience emotional instability, challenges in emotion regulation, and increased risk for the onset of psychopathology, including depression. Adolescents also engage in more social media use (SMU) than any other age group. There is significant interest inside and out of the scientific community regarding how SMU is implicated in healthy versus unhealthy adolescent emotional well-being during this developmental shift in emotional experiences, particularly among girls, who may be most vulnerable. Although research on how adolescent girls’ emotional well-being may be associated with their SMU has increased over the past decade, findings have been largely mixed and inconclusive. This may be …

Medical Recommendations And Bmi Among Black And Hispanic Adolescent Females, Dorothea Polk

Walden Dissertations and Doctoral Studies

Adolescent obesity persists as a critical public health challenge in the United States, with Black and Hispanic adolescent females experiencing elevated rates. Adolescent obesity contributes to serious long-term health risks, but provider counseling may support body mass index (BMI) management. Guided by the social-ecological model, this study examined whether receiving medical recommendations to control or lose weight was associated with BMI among Black and Hispanic adolescent females aged 16–19 years and whether meal preparation habits and food security status moderated this association, controlling for age, household income, and race/ethnicity. This quantitative, cross-sectional secondary analysis used multiple linear regression analyses to …

Mining Legacy And Wildfires: Interfacial Reactions Affecting Metal Mobility, Eresay Alcantar-Velasquez

Earth and Planetary Sciences ETDs

We identified water labile interfacial reactions between laboratory burned pinewood ash and mine waste solids that influence metal mobilization. The Upper Gallinas Creek Watershed in New Mexico is affected by wildfires and mining legacy. Pinewood and mine waste sediments were sampled from the area, and the pinewood was burned at 350°C to simulate medium burn intensity ignition. Rapid desorption and gradual dissolution of Mn and Fe was detected by ICP-MS as pH decreased over time. After reacting 18 MΩ ultra-pure water with a mixture of pinewood ash and mine waste sediments Fe (143%) and Mn (89.2%) concentrations increased over time. …

On Food, Politics, And The Power Of Representation In The American History Museum, Mason A. Bright

Museum Studies Theses

This study explores the political implications of foodways-related interpretation at American history institutions, situating it within current partisan discourse. Using an “Anthropology of Museums” framework, I place literature from the fields of food history, human geography, and museum studies in conversation with interviews with three curatorial professionals from the National Museum of American History, the Henry Ford Museum of American Innovation, and the New Mexico History Museum. I understand the ways these professionals navigate politically engaged interpretation through the lens of ethnographic refusal, a phenomenon drawn from the anthropology subfield of resistance studies. I argue that the connections between food …

Gradients Of Abandonment, William Tatman

Geography ETDs

As urban-rural disparities drive depopulation in rural areas worldwide, local strategies emerge as pathways for resilience. Research on Ojika, a Japanese island that has lost 75% of its population since the 1960s, reveals an Abandonment Gradient: a nuanced pattern of disuse adapted to modern polycrises. Extending the concept of "lying fallow" to homes and infrastructure, this thesis focuses on abandonment practices that reflect complex realities of labor, capital, and climate uncertainty. Rather than viewing depopulating communities as passive victims of out-migration, this paper argues they are critical sites for generating crisis response. Communally crafted attitudes toward unused space and more-than-human …

Cbd's Impact On Learning, Memory, And Anxiety: A Dose Response, Audrey Camacho

Psychology ETDs

Cannabidiol (CBD) is widely utilized for its therapeutic properties, yet its impact on an unmanipulated model at baseline behavior remains poorly understood. This study investigates CBD’s dose-dependent behavioral profile on spatial learning, memory, and anxiety using Long-Evans rats. Subjects received a vehicle, 20 mg/kg, or 40 mg/kg CBD dose prior to assessment in the Morris Water Task (MWT) and Elevated Plus Maze (EPM). MWT results indicated consistent Day 1 learning, but the 40 mg/kg dose induced a temporary disruption 24 hours post-treatment. Performance returned to baseline by day 6. On the EPM, traditional anxiety markers remained unchanged. While CBD did …

Elucidation Of Micro/Nanoplastic Signature Of Human And Murine Lung Tissue Utilizing Pyrolysis-Gas Chromatography/Mass Spectrometry, Aerlin D. Decker

Pharmaceutical Sciences ETDs

Micro-and Nanoplastics (MNPs) are ubiquitous biological pollutants that have been identified throughout a variety of biological samples. MNPs have been detected in several human tissues, such as the brain, kidneys, and liver. Lung tissue remains understudied for MNP accumulation despite the large surface area and clear path for exposure. Using Pyrolysis-Gas Chromatography Mass Spectrometry (Py-GC/MS), human lung tissue was evaluated for 12 different polymers, enabling quantification of total plastic per gram of tissue to be identified. Further analysis was performed with Inductively Coupled Plasma Mass Spectrometry (ICP-MS) to investigate heavy metal accumulation in human lung samples and determine whether a …

Design And Feasibility Study Of An Air-Cooled Reactor Cavity Cooling System For Fluoride-Salt-Cooled High-Temperature Reactors, Alexandra D. Martinez

Nuclear Engineering ETDs

Licensing efforts for Fluoride-Salt-Cooled High-Temperature Reactors (FHRs) are dependent on passive safety systems designed for decay heat removal, yet no prior study has evaluated an air-based Reactor Cavity Cooling System (RCCS) for this role. This thesis addresses that gap by determining whether an air-cooled RCCS can be designed to passively remove post-shutdown decay heat from the Mk 1 FHR. An RCCS configuration was developed and sized using a one-dimensional lumped-parameter design methodology, then evaluated through system-level thermal-hydraulic modeling in RELAP5-3D under a conservative, lower-bound post-shutdown transient. The analysis characterizes the radial heat-transfer pathways from the FHR core to the RCCS …

Development Of Dynamic Proof-Mass Configurations For Broadband Piezoelectric Energy Harvesting, Nico E. Galarza

Electrical and Computer Engineering ETDs

The purpose of this thesis is to investigate and develop dynamic proof-mass configurations for broadband piezoelectric energy harvesting. Conventional piezoelectric energy harvesters are typically limited by narrow operating bandwidths, restricting their performance under variable-frequency excitation. This research presents the design, fabrication, and experimental evaluation of multiple proof-mass concepts intended to increase the usable frequency range of cantilever-based piezoelectric energy harvesters. Several dynamic mass configurations were developed using additive manufacturing techniques and integrated with commercially available piezoelectric cantilevers. Experimental testing was conducted under controlled vibration conditions to characterize voltage response, resonant behavior, and bandwidth performance. The results demonstrate that dynamic proof-masses …

Notch Signaling Regulates The Secretion Of Pro-Metastatic Factors In Extracellular Vesicles In Liposarcoma, Menchus Quan, Yi-Kai Liu, Ying Zhao, Madeline Kay, Kai Sun, Timothy P Gavin, Raphael E Pollock, W Andy Tao, Shihuan Kuang

The Brown Foundation: Institute of Molecular Medicine

Notch signaling is an emerging regulator of liposarcoma (LPS), but its role in mediating communication with the tumor microenvironment (TME) is unclear. Here, we investigate how Notch activation (NICD overexpression) alters the proteomes of LPS-derived extracellular vesicles (EVs). We used quantitative mass spectrometry to profile the EV proteome in multiple contexts: cultured LPS cells, LPS tumor, circulating EVs of LPS-bearing mice, and human LPS samples. We found that Notch signaling increases the secretion of EV proteins that favor tumor progression and metastasis but suppresses immune responses in murine LPS cells. Overlapping murine and human LPS data identifies 18 proteins that …

Timelines Over Tokens: Summarization, Prompting, And Explainable Fine-Tuning For User-Level Suicide Risk Detection, Aditya Tekale

Master's Theses

This research presents a two-stage pipeline for user-level suicide risk detection from Reddit: first, inference-only prompting with summarization; second, fine-tuned encoder classification with explainability and expert validation. The data are user-level: each of the 500 C-SSRS Reddit items is one user’s chronologically concatenated posts and comments (a user timeline), annotated by psychiatrists. Stage one: six prompting strategies zero-shot, few-shot, chain-of-thought, tree-of-thought, least-to-most, and self-consistency are evaluated across six LLMs on multi-class and binary formulations; simple zero-shot achieves the highest balanced accuracy (0.53 multi-class). Error analysis shows longer inputs associate with misclassification (p = 0.002); domain-specific summarization (timelines >2,000 tokens) reduces …

The Relationship Between Strength Training And Burnout, Maddie R. Barrientos

Master's Theses

The purpose of this study was to comprehensively examine the relationship between strength training and burnout to assess whether consistent engagement in strength training would be associated with lower levels of burnout. Results of an online survey administered to 119 participants revealed that those who did strength train versus those who did not did not significantly differ in their levels of burnout, but among those who did strength training, there were significant differences in levels of burnout with how they engaged in strength training. The greater frequency of strength training participation and the greater number of muscle groups trained were …

Impacts Of Agricultural Microplastics On The Growth Of Marine Phytoplankton In Monterey Bay, Olivia A. Pawlyk

Master's Theses

Agricultural plastics are an emerging source of microplastics (MPs) to coastal marine environments, yet their effects on marine phytoplankton remain poorly understood. In coastal regions surrounding Monterey Bay (California, USA), plastic mulch used in agriculture can fragment into MPs during weathering and removal, entering marine waters via runoff and wind transport. This study investigated the effects of environmentally relevant concentrations of agricultural MPs on the growth and physiology of four marine phytoplankton species: two harmful algal bloom (HAB) taxa (Alexandrium sp. and Pseudo-nitzschia multiseries) and two non-HAB taxa (Thalassiosira sp. and Prorocentrum sp.). Each species was cultured independently and exposed …

Depth-Dependent Effects Of Disturbance On Reproductive Output And Growth Of Giant Kelp (Macrocystis Pyrifera), Roxanne-Alexa Amalia Garibay

Master's Theses

Understanding the resilience of foundation species to disturbance, such as the canopy-forming giant kelp (Macrocystis pyrifera), is crucial as these species support diverse communities by provisioning habitat and nutrients. This study investigated sublethal effects of biomass loss on reproductive traits and the recovery of vegetative biomass following simulated disturbance at shallow and deep sites in Stillwater Cove, central California. Initial baseline morphometrics revealed that depth significantly influenced total frond length and blade density but did not predict other vegetative or reproductive biomass metrics. A manipulative experiment varying type and intensity of disturbance—from canopy removal to full frond culls—demonstrated a decoupled …

Biologically-Based Alternatives To Plastic Mulch Enrich Microbiome And Buffer Yield In Small-Scale Strawberry Production, Olivia L. Fragiacomo

Master's Theses

Much of commercial agriculture has used plastic mulch since the 1950s to contain fungicides and fertilizers, control weeds, retain soil moisture, and warm the top soil to start the growing season earlier. Research suggests that small-scale strawberry (Fragaria x ananassa) growers may be able to incorporate biological techniques, such as wheat straw mulch with microbial amendments, to reduce the use of single-use plastic mulch with a comparable yield. For this study, I carried out a randomized complete block comparison of five strawberry management techniques: plastic mulch (PM), straw mulch alone, and straw mulch inoculated with either arbuscular mycorrhizal fungi (AMF), …

Water Availability Regulates Maize Reliance On Soil Versus Fertilizer Nitrogen In A Semiarid Environment, Dwarika Bhattarai, Janet Moriles Miller, Sharon A. Clay, David E. Clay

Agronomy, Horticulture and Plant Science Faculty Publications

In semiarid environments, early-season water deficits create uncertainty in how much and when N fertilizer should be applied. To minimize indecision, a better understanding of the interrelationships among water availability, N rate, plant N sources, and yields is needed. This study investigated how soil water availability influenced maize (Zea mays L.) yields and utilization of soil- and fertilizer-derived N in semiarid environments in 2020 and 2021. The replicated trials were conducted at 12 sites and determined the impact of water availability and N rate on the sources of N within the grain, and precipitation and N use efficiencies (PUE …

Ophthoevidence Report: Comparative Effects Of Prophylactic Strategies For Post-Intravitreal Injection Endophthalmitis: Protocol For A Systematic Review And Network Meta-Analysis, Maryam Ghadimi, Dena Zeraatkar, João Pedro Lima, Jinhui Ma, Sunir J. Garg, Peter Kaiser, David Steel, Tien Yin Wong, Sobha Sivaprasad, Charles Wykoff, Varun Chaudhary

Wills Eye Hospital Papers

BACKGROUND: Endophthalmitis is a rare but serious complication of intravitreal injections (IVI). To mitigate the risk of post-injection endophthalmitis (PIE), retinal specialists use different strategies, combining various prophylactic measures. However, existing systematic reviews have evaluated the effects of these measures in isolation, which does not consider their concurrent use in practice. A trustworthy systematic review with network meta-analysis (NMA) by providing a framework for simultaneous comparisons of different prophylactic combinations is essential to guide decision-making.

OBJECTIVES: To present a protocol for addressing the comparative effects of different strategies for the prevention of PIE.

METHODS: We will search Medline, EMBASE, Cochrane …

The Mediating Role Of Moral Disengagement In The Relationship Between Facets Of Empathy And Aggression, Romiere J. Horace

Theses

Aggression is a major social and public health concern with economic, psychological, and interpersonal implications. Extensive research has examined the potential antecedents for aggressive behavior, with many different environmental, biological, and intrapsychic factors being significantly associated with aggression. Researchers have also focused on cognitive mechanisms, like empathy, as a protective factor for aggression. More specifically, research has linked lower levels of empathy to higher levels of aggression; however, the underlying mechanisms of this relationship remain underexplored. A potential explanatory mechanism is moral disengagement, which allows individuals to justify harmful behaviors and avoid self-sanctions. However, limited research has examined these constructs …

Womanhood On The Veranda: Maternalism And The Expansion Of American Women's Public Life, Abigail J. Swanson

History ETDs

Motherhood and child welfare became central organizing principles for reform during the United States Progressive Era.  From these guiding principles, the government formed the United States Children’s Bureau. It was the country's first governmental agency that focused solely on the welfare of children. Mothers writing to the federal government for motherhood advice was a phenomenon that was completely new to twentieth century mothers. Women took pride in their roles as mothers, particularly when it came to child health matters. To the generation of mothers who came before these early twentieth century letter writers, asking the government for advice on child …

Unbroken Sovereignty: Land, Water, Education, And Nakoda And Oc̣Eti Ṡaḳowiŋ Tribes Of The Fort Peck Indian Reservation, 1850–1935, Richard Joseph Maska

History ETDs

This dissertation explores the intersection of sovereignty and development among the Nakoda (Assiniboine) and Oc̣eti Ṡaḳowiŋ (Sioux) Tribes of the Fort Peck Indian Reservation during the late nineteenth and early twentieth centuries. Methodologically, it draws on a critical reading of archival sources in conjunction with community input. It traces the emergence of reservation policy, government sponsored education, the imposition of allotment policy and private landownership, and the impact of state-sponsored irrigation and other development projects. I argue that the Tribes forged webs of affiliation and kinship to both assert their nationhood and navigate their involvement in such projects. These expressions …

Abiquiú And Georgia O’Keeffe Neighbors In A New Mexico Village, Katherine E. Mccully

History ETDs

This thesis centers the people of Abiquiú, a small town in northern New Mexico, and discusses their history through the twentieth century into the twenty-first century. I have collected oral histories of Abiqueños, their families, and lives in Abiquiú. More specifically, this thesis explores their experiences of residing with a famous person, artist Georgia O’Keeffe, while maintaining their traditions as a Genízaro village. This thesis is not written solely about O’Keeffe, but, as much as possible, emphasizes the perspectives of the Abiqueños and Abiquiú, while O’Keeffe resided in their community. I seek to write the little-told story of O’Keeffe through …

Inoculation Interventions, Prebunking, And Media Literacy Education Are Not The Same, Author Information Removed

JMLE Submissions Open for Review

Inoculation theory-based interventions, prebunking, and media literacy education are often discussed together because all three can help people resist harmful information. Their overlap, however, does not make them interchangeable. This essay argues that clearer distinctions are needed, especially between inoculation and prebunking. Inoculation theory centers on threat-motivated resistance to influence, whereas prebunking is more accurately understood as refutational preemption. Media literacy education is a broader educational context in which either approach may be used. I focus in particular on the difference between forewarning and threat, arguing that forewarning may reasonably support inferences about threat in some contexts but should not …

How Misinformation Literacy Relates To Political Participation: An Extended Communication Mediation Model, Author Information Removed

JMLE Submissions Open for Review

This study examines how misinformation literacy is associated with political participation in digital environments through psychological and behavioral pathways. We extend the Communication Mediation Model (CMM) by integrating it with media literacy scholarship and locus of control theory. Rather than treating media literacy as a single formal theory, we conceptualize it as a scholarly framework that specifies the competencies through which individuals access, analyze, evaluate, create, and act on media messages. Within this framework, misinformation literacy refers to applied competence in recognizing, evaluating, resisting, and responding to false or misleading information. Using survey data from 499 U.S. adults, the analysis …

Civilian Threat Reduces Distance Perceptions And Officer Punishment In Police Use-Of-Force Encounters, Stephanie A. Cárdenas, Kristyn A. Jones, Yael Granot, Emily Balcetis

Psychology: Faculty Publications

People turn to video evidence to make judgments about the justifiability of an officer’s actions in use-of-force incidents. Despite beliefs that video offers an objective account of events, use-of-force footage elicits different judgments among those watching it. Across four experiments (Ntotal = 2615), we investigated whether discrepant punishment judgments arise in part because of differences in perceptions of the physical space that separates an officer and civilian. We focus on third-party observers’ subjective perceptions, as they shape public discourse and justice outcomes, influence institutional accountability, and fuel public response. Despite watching the same video, civilians appeared physically closer to officers …

Enhancing Nursing Self-Efficacy In Advance Care Planning Conversations Through Role-Play Education: A Quality Improvement Project, Rachel Williams

DNP Projects

Background:
Advance care planning (ACP) conversations are essential for ensuring that patient healthcare preferences are understood and respected; however, nurses often report limited confidence and self-efficacy when initiating these discussions. Educational interventions that emphasize communication skills may improve nurses' preparedness to engage in ACP conversations.

Methods:
A quality improvement project utilizing a pre-post intervention design was conducted on three adult inpatient medical units within a regional Midwestern hospital. Registered nurses participated in an educational intervention consisting of ACP education, role-playing case scenarios, guided discussion, and debriefing. A modified 22-item Advance Care Planning Self-Efficacy Questionnaire was administered before and after the …
