Evaluation Of The Physicochemical Properties And Soil Biogeochemistry Of Fire Residues, Lingqun Zeng

Electronic Theses & Dissertations (2024 - present)

Wildland fire is a main driving force in the Earth system and affects ecosystem properties and processes across spatio-temporal scales. The burning of biomass and production of solid fire residues (conventionally termed fire ash) that are a mixture of completely and incompletely burned materials (inorganic ash and pyrogenic carbon), represent the direct and prominent changes by fires. Cycling of the fire residues is an integral component of elemental cycles and can mediate other biogeochemical processes.

This dissertation aims to fill important knowledge gaps in understanding the disturbance of wildland fires to biogeochemical processes in soils. First, this work characterized and …

Banking And Antitrust, Saule T. Omarova, Graham S. Steele

Faculty Publications

Money is power. Banks have the extraordinary power to create the nation’s money and credit, which they are entrusted to channel into productive economic uses. Like most other forms of economic power, this publicly granted privilege can be abused for private gain. That is why the “money monopoly” and “money trusts” were once considered one of the most dangerous forms of concentrated private wealth, an existential threat to economic freedom and American democracy. Yet, for the past half-century, the law governing banks and the law curbing monopolies have occupied doctrinally and normatively separate spaces. Today, banking law is seen predominantly …

"The Only Disability In Life Is A Bad Attitude": A Quantitative Exploration Of The Impacts Of Inspiration Porn, Anna H. Burt, Megan Mccarty

Modern Psychological Studies

Inspiration porn is a social media representation of visibly disabled individuals performing physical activities accompanied by short motivation captions meant to inspire viewers. Critics of inspiration porn hold that it misrepresents the reality of disability and negatively impacts disabled people. This study aimed to quantitatively explore the impacts of inspiration porn on various disability-related variables, as there is limited research on this topic. We hypothesized that exposure to inspiration porn would increase system justification and belief in a just world, decrease support for disability-related policies, and cause viewers to view disabled individuals as sources of inspiration. We also had several …

The Impact Of Parent-Child Interactions On Emotion Regulation In Adulthood, Bridget Burgoyne, Holly Grant-Marsney

Modern Psychological Studies

Childhood is a time where emotional skills are formed. These skills often reflect the primary caregiver(s) modeling and interactions which may shape emotional intelligence. This research aimed to assess if specific parenting approaches have lasting effects on a person’s ability to emotionally regulate. The sample included 141 adults, who responded to questions reflecting the parenting approaches they observed, and their current state of emotional regulation. Results from our regression analysis showed when controlling for age, parental warmth in childhood predicted one’s later ability to use cognitive reappraisal skills. Results from our correlational analysis showed strong positive associations between overindulgence, cognitive …

Body Dissatisfaction In College Students: Which Sociocultural Pressure Best Predicts Drive For Thinness?, Sawyer V. Ellis, Elaine M. Kozmiuk, Mary E. Pritchard, Heather Schoenherr

Modern Psychological Studies

Previous literature has suggested that family pressure is the main predictor of drive for thinness (Palladino Green & Pritchard, 2003). Given the growth of social media where thin beauty is glamorized, we wanted to test if this remains true while including multiple factors that may have been disregarded in body-centric studies. Consequently, we asked which sociocultural pressure—family, peers, or media—relates the strongest with body shame, body surveillance, and drive for thinness. A sample of 1,049 undergraduate psychology students, ages 18-29, were surveyed to better understand body dissatisfaction in college students. We predicted that each sociocultural pressure would correlate with body …

Body Image And Social Media In College Students, Elaine M. Kozmiuk, Sawyer Ellis, Mary Pritchard, Heather Schoenherr (Mentor)

Modern Psychological Studies

The current study assessed the relationship between social media appearance-related preoccupation (SMARP), body shame, body surveillance, and social physique anxiety (SPA). Data were collected from 1,049 participants, and a correlational analysis and a hierarchal regression were conducted. Significant relationships were found between body shame, body surveillance, SMARP, and SPA, supporting our hypotheses. Our results confirmed the relationship between SPA and SMARP, adding evidence to a mixed debate about the relationships between SPA and social media use. The researchers found that SPA moderated the relationship between body shame and SMARP. We can conclude that appearance anxieties and appearance-based social media use …

Perceived Educational And Entertainment Value Of Positive And Negative Portrayals Of Racial Minority Characters In Films, Hallie Filan, Evan F. Edwards, Kate E. Hembree, Tammy Sonnentag

Modern Psychological Studies

Racial/ethnic minority characters are increasing in films; yet, despite increasing representation, less than half (39.7%) of all films in 2020 cast a main character who was a racial/ethnic minority. Because media representations can perpetuate racial/ethnic stereotypes, the present study examined if negative (compared to positive) racial/ethnic representations of Black and Chinese characters (and their cultures) in films impact individuals’ evaluations of the educational and entertainment value of the content. One hundred and eight undergraduate students were randomly assigned to view scenes portraying African American and Chinese characters (and their cultures) positively or negatively from two popular animated films—The Lion King …

Interactions Between Anxiety, Family Influence, And Athletic Status On College Students: A Military School Cohort, Caragh Osborne, Aubrey Whitehead

Modern Psychological Studies

The prevalence of anxiety in college students has increased drastically over the past decade. Previous researchers have typically only examined how to help students while they are at school, however, there could be additional factors contributing to their anxiety prior to attending college. The current study aimed to observe how family influence and athletic status may play a role in anxiety among college students. Participants (N = 42) completed an anxiety symptoms inventory then disclosed how much their family influenced their decision to attend college. A two-way ANOVA indicated that neither athletic status nor degree of family influence had a …

Though the field has identified the factors that have contributed to negative physical and mental health changes, there remains much to be known about social and cultural protective factors that could buffer the negative role of the COVID-19 pandemic on Latinx college students. The current study contributed to the literature on the mental health outcomes of Latinx college students by identifying a possible mediator and moderators between the …

Trait Mindfulness And Political Polarization: Investigating Neural Responses And Emotional Orientations, Elif Z. Celik

Theses and Dissertations

The rapid escalation of political polarization has led to increased social distancing, aggressive partisan behavior, and discriminatory attitudes among Democrats and Republicans. Prior research has indicated that mindfulness is associated with increased compassion, reduced prejudice, and diminished aggression toward out-group members. This thesis investigates the relationship between trait mindfulness and political polarization by examining neural responses and emotional orientations in individuals with varying levels of mindfulness. This research measured brain activity using functional near-infrared spectroscopy (fNIRS) while participants viewed emotionally charged political videos and neutral content. The primary hypothesis suggested that individuals with high trait mindfulness would exhibit left-lateralized prefrontal …

Title: I: L1-Norm Matrix Completion For Recommender Systems Ii: Conjecturing-Based Classification, Fatemeh Valizadeh Gamchi

Theses and Dissertations

Recommendation systems are essential for providing personalized user experiences, but their performance can be affected by outliers especially in traditional collaborative filtering methods that use the L2-norm. To address this challenge, we developed two new algorithms, SharpEl1rs and SharpEl1rs-Impute, based on the L1-norm to improve resistance against extreme values and effectively handle missing data. Our experimental setting was designed to compare these proposed methods with existing techniques. Then our algorithms are applied to real datasets to assess their performance, with findings indicating that our proposed models offer improved accuracy in some cases and solid performance in others for industrial-scale recommendation …

Not Woman Enough: How World Athletics’ Treatment Of Women With Differences In Sexual Development Violates The Olympic Charter And The Un’S Conventions Against Racial Discrimination And Discrimination Against Women, Rachel Crass

Denver Journal of International Law & Policy

In 1966, in response to growing fears that men would attempt to pose as women to win medals in elite competition, the International Olympic Committee (IOC) began gender testing all female athletes through various visual and gynecological evaluations. These tests were quickly deemed to be too invasive and were replaced by other chemical and genetic tests as scientific capabilities advanced. The new tests led to the disqualification of dozens of elite female athletes after results revealed latent Y chromosomes in women with androgen insensitivity conditions. After multiple leading medical societies and international sports governing bodies called for an end to …

Considering Systems Of Power And Black And Latine Students’ Belonging In Stem, Korinthia D. Nicolai

Theses and Dissertations

This dissertation focuses on (a) exploring the need for and strategies to facilitate the integration of Critical Race Theory (CRT) and educational psychology and (b) supporting Black and Latine students through examining the impact of systems of power via the integration of belonging and Critical Race Theory. This dissertation follows a three-paper format. In Paper 1, we recognize that psychology researchers can use CRT to explore race and racism. However, psychology scholars may confront growing pains when integrating CRT due to their respective inquiry worldviews–postpositivism and critical–which result in several tensions. These tensions may limit the uptake of CRT in …

Call For Me When You Get There: I'Ll Be Among The Crows, Jessica O. Tifase

Theses and Dissertations

I've always been intrigued by the ways in which the notion of flight has been used to describe the movement of Black people, both literally and figuratively. In many instances, flight performs as a double entendre, embodying multiple meanings: to escape or to transcend. The fluidity of its definition prompts a reflection I’ve been wrestling with as I move through the world: Are Black people in a perpetual state of flight?

In my thesis exhibition, Call for Me When You Get There, I use the precarious state of flight as a means to explore the complicated choreography necessary for navigating …

A Data-Driven Approach To Time-Domain Electromagnetic Modeling Based On Dynamic Mode Decomposition, Yanming Zhang, Steven Gao, Lijun Jiang

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

This paper presents a data-driven methodology that utilizes Dynamic Mode Decomposition (DMD) for the time-domain (TD) electromagnetic (EM) modeling of microwave devices. As an unsupervised machine learning technique, DMD leverages a limited set of unlabeled spatio-temporal electromagnetic (EM) data to determine DMD eigenvalues and eigenmodes. Then, the obtained DMD model reconstructs the dynamics as a series of exponential terms based on linear assumptions. The effectiveness of this approach is demonstrated through the TD EM modeling of photonic crystal waveguides. Comparative analysis with the finite-difference time-domain (FDTD) method shows that the DMD model not only achieves precise modeling but also facilitates …

Would Self-Supported Fracture Contribute To The Hydrocarbon Production In Shale Reservoir Besides Proppant-Supported Fracture, Y. Sun, G. Li, S. Zeng, J. Wu, J. Liu, M. Xu, C. Dai, Baojun Bai

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

During hydraulic fracturing in deep shale gas reservoirs, it is difficult to pump proppants long distances, and self-supported fractures are formed at the far and upper ends of the fractures. The self-supported fracture could hold the fracture space by its surface structure again fracture closure. However, it faces various aspects of impairment during shale gas reservoir development, which affect its conductivity. Among the impairment, long-term production results in a decline of bottom hole pressure, which will compact the fracture space, and self-supported fractures without proppant are more sensitive than those with proppant. In this paper, we conducted a series of …
