Threat-Related Mental Imagery Reduces Endogenous Pain Modulation In Healthy Individuals, Julie L. Ji, Meghan Whitehouse, Sam Mugglestone, Sam W. Hughes

School of Psychology

Mental imagery-based simulations of threat can evoke “as-if-real” emotional and motivational responses, which may alter top-down pain processing. This study investigated the impact of mental imagery simulations of threat on endogenous pain modulation in n = 71 healthy participants using a cuff-pressure algometry protocol. In block one, participants were assessed on their baseline pain detection threshold (PDT), pressure pain tolerance (PTT), and their conditioned pain modulation (CPM) responses. In the second block, participants underwent the same procedures again but were randomly allocated to imagine the dominant leg cuff as being made of bubble-wrap (benign imagery condition; n = 36) or …

Together In Sync: Assessing Prosocial Behavior With A Full-Body Interactive Mixed Reality Experience, Sena Beste Ercan, Belen Gonzalez, Olga Gali, Gray Atherton, Liam Cross, Narcis Pares

School of Psychology

This study investigates how interpersonal synchrony (IPS) in full-body interactive Mixed Reality (MR) environments can shape children's prosocial behavior. We introduce DragonIce 2.0, a two-part MR game designed to induce synchronous or asynchronous group activity and assess their impact on prosocial behavior. To examine changes in affiliation (team belonging and peer liking) and collaboration (overt joint actions), we conducted a comparative study with children aged 9–10, using both system logs and self-report measures. The results highlight the importance of context, task structure, and perceived coordination in shaping social outcomes, offering insights into how interaction dynamics shape social engagement in immersive …

Advancing Peripheral Nerve Regeneration (Nerve Space 2025), Ken Porche, Tara Sara Saffari, Hollie Power, Wesley P Thayer, S Shelby Burks, John C Elfar, Alexander Y Shin, David M Brogan

2020-Current year OA Pubs

UNLABELLED: Peripheral nerve injuries remain a major clinical challenge due to slow axonal regeneration, rapid Wallerian degeneration (WD), and degeneration of target organs prior to reinnervation.

WHERE ARE WE NOW?: Strategies to enhance regeneration can be broadly divided into three categories: preventing or delaying WD, speeding up axonal regeneration, and improving the molecular environment at the injury site. Approaches to delay WD include polyethylene glycol-mediated axonal fusion, which may restore early axonal continuity and conduction, and inhibition of sterile alpha and TIR motif-containing 1, the central executioner of WD, with small-molecule inhibitors now in clinical trials. Methods to accelerate axon …

Reactive-Fluid-Transport Controls On Co2-Eor Applications In The Upper Red River Carbonate Reservoir, Abdelmalek Abes

Theses and Dissertations

Reactive-transport phenomena during CO2 injection in carbonate reservoir were examined in detail. Three core samples from the primary producing units of North Dakota’s Upper Red River Formation (U2-H055, U4-H069, and U6-H009) were used to experimentally investigate geochemical reactions and petrophysical alterations, impacting carbon dioxide enhanced-oil-recovery (CO2-EOR) and geologic-carbon-storage (GCS) projects. During corefloods using a CO2/brine mixture, two samples demonstrated early permeability increases followed by declines, whereas the third sample demonstrated an early decrease; all samples gradually recovered at a later stage. Nuclear magnetic resonance (NMR) measurements revealed slight porosity increases due to dissolution-induced wormholes, while the pore-size distribution (PSD) shifted …

Student Engagement As A Predictor Of Stem Student Success, Mosab Shaher Abu Al Foul

Theses and Dissertations

This quantitative study investigates factors influencing engagement, persistence, and degree completion among underrepresented minority (URM) students in science, technology, engineering and math (STEM). Guided by Tinto’s Interactionist Model (1975) and Bandura’s Self-Efficacy Theory(1977), it examines how institutional practices and socioeconomic conditions contribute to inequities in student outcomes. Using a non-experimental, correlational design, the study analyzes National Survey of Student Engagement (NSSE) data and institutional records from a Midwestern Research 2 university (N = 620; URM subsample n = 52). Binary logistic regression, MANOVA, and t-tests were used to assess relationships among High-Impact Educational Practices (HIEPs), engagement indicators, faculty interaction, pre-college …

Climate Messages In An Ai-Integrated Experiment: Interpretive Divergence, Policy Support, And A New Resonance Consistency Framework, Jayme Colosimo

Theses and Dissertations

This dissertation examined how environmental frames—particularly “Mother Earth” and “Mother Nature”—influence public support for climate policy and how these effects differ across demographic groups. Using a mixed-methods explanatory sequential design, the study executed a media survey experiment (N = 470) followed by semi-structured expert interviews to assess responses to two primes using a conventional corporate media message, and a message with similar content that was generated by Artificial Intelligence (AI).

Quantitative findings showed that these metaphors generated uneven and sometimes divergent priming effects. Some groups—most notably White male Republicans—reported higher support for environmental policy under the conventional media prime. Under …

Self-Talk In Esports: Extending Sport Psychology Frameworks To Digital Competition, Brett Anne Thompson Machamer

Theses and Dissertations

Self-talk is a key mechanism underlying performance, confidence, and emotional regulation, yet its use in esports remains underexplored. This study examined self-talk patterns among esports players, focusing on associations with hours played, self-talk type and valence, and contextual and motivational factors influencing its use. Esports players (N = 102; M = 18.53 hours/week, SD = 13.74) across a range of competitive levels completed an online questionnaire assessing self-talk type, valence, and contextual use. Greater hours played were associated with increased use of strategic self-talk, while self-talk valence was not significantly related to time spent playing. Participants most frequently reported using …

Filling The Gaps: Rural-Remote High School Teachers’ Perceptions Of Professional Training In Student Mental Health Preparedness, Angela N. Muhs

Theses and Dissertations

Rural-remote high school teachers are frequently the first to notice and respond to student mental health concerns, yet they operate within communities characterized by significant shortages in mental health providers. Access to professional mental health services in these settings remains persistently limited, placing considerable responsibility on teachers who may lack adequate preparation. This study employed an interpretive case study design to qualitatively examine how rural-remote high school teachers in North Dakota perceive their professional training and overall preparedness in addressing student mental health concerns. Twelve licensed teachers, whose experience ranged from six months to 33 years, participated in in-depth interviews. …

Ground Penetrating Radar Spiral Antenna Transient Response Based On Target Radar Cross Section, David Rohde

Theses and Dissertations

This dissertation presents a significant advancement in Ground Penetrating Radar (GPR) detection technology through the development of a novel method for the detection and classification of buried conductive objects using custom-designed Archimedean spiral antennas. The research demonstrates that the transient electromagnetic response of an Archimedean spiral antenna is strongly correlated with the Radar Cross Section (RCS) characteristics of buried objects operating within the radar resonance scattering, or Mie, region. By leveraging this relationship, the proposed approach enables not only the detection of buried objects, but also generalized classification based on object geometry and size.A primary contribution of this work is …

Exploring Student Emotions And Needs In Pre-Medical Laboratory Science Education: A Control-Value Theory Approach, Allison Jean Waswick

Theses and Dissertations

There is a current workforce shortage of qualified medical laboratory scientists (MLS) in the healthcare field. Without these individuals completing their analysis of patient samples, patients may experience detrimental effects to their health. To help narrow the gap between the number of open positions and the number of MLS graduates per year, MLS programs could better understand pre-MLS students’ needs to better support and retain them. Using Control-Value Theory as the framework for this qualitative study, this study explored pre-MLS students’ needs by examining the emotions they experienced in their programmatic contexts to better understand this population’s needs. Five themes …

Techno-Economic Analysis And Density Functional Theory Modeling Of Hydrogen Fuel Cells With Platinum-Based Catalysts For Effective Deployment In Long-Range Electric Vehicles, Thomas Cheekwang Yap

Theses and Dissertations

The transition to sustainable transportation is constrained by carbon emissions and fossil fuel dependence. Hydrogen fuel cells (HFCs), particularly those utilizing platinum-based catalysts, offer high efficiency and suitability for long-range electric vehicles (EVs). However, the high cost and durability limitations of platinum catalysts remain major barriers to large-scale deployment.

This study integrates techno-economic analysis (TEA) with density functional theory (DFT) modeling to evaluate cost–performance trade-offs of platinum-based catalysts for long-range hydrogen fuel cell vehicles. DFT simulations were conducted to assess platinum alloy compositions and oxygen reduction reaction activity. These performance metrics were incorporated into a MATLAB-based TEA framework to quantify …

Cannabinoid Modulation Of Metabolic Dysfunction Associated Steatotic Liver Disease In A Mouse Model, Kira Villarreal

Undergraduate Honors Theses

The liver plays an essential role in regulating metabolism. Though, when the physiology of the liver is thrown off, this can lead to pathological states. Metabolic dysfunction associated steatotic liver disease (MASLD) can be a consequence of irregular physiological state in relation to metabolism. MASLD is the leading chronic liver disease globally with estimated 30% of patients affected, and incidence rates expected to rise. MASLD is diagnosed when there is a >5% build up of lipids in the hepatocytes and is not associated with high alcohol consumption. There are many risk factors associated with MASLD, such as high fat or …

The Role Of Art-Based Pre-Performance Rituals For Collegiate Student-Athletes And Their Perceived Effects On Mental Preparation, Haylee P. Robinson

Undergraduate Honors Theses

This paper will explore whether collegiate student-athletes at the University of Northern Colorado (UNCO) engage with art-based pre-performance rituals (PPRs) and, if so, examine their perceived effects on mental preparation prior to competition. Research has discussed traditional preparatory routines (PRs)—breathing techniques, visualization, goal setting, and problem-solving—creating a gap for understanding how creative or symbolic rituals function in the realm of collegiate sports. Combining Clifford Geertz's (1973) anthropological framework of ritualized behaviors acting as “meaning-making systems” with empirical evidence supporting art therapy, this research positions symbolic art-based interventions as PPRs, helping athletes with focus, emotional regulation, and confidence prior to competition. …

Faculty Publications

Crops are continually challenged by biotic stresses, including fungal, bacterial and viral pathogens and insect pests, which cause substantial yield and quality losses worldwide. WRKY transcription factors constitute a plant-specific and functionally diverse family that is central to immune regulation. Recent advances in genomic resources and multi-omics approaches have accelerated the identification and functional characterisation of WRKYs in crops. This review summarises the structural features and classification of WRKY genes and their genome-wide distribution across crop species. It also synthesises WRKY-centred regulatory modules that mediate resistance to major classes of biotic stress. In antifungal defence, WRKYs reinforce pattern- and effector-triggered …

Weaving Ideology: Textiles In Florentine And Venetian Painting Of The Cinquecento, Ruben Verità

Art and Art History Honors Projects

Renaissance art historical scholarship has largely ignored the political and cultural significance woven into the representation of textiles, as well as their communicative potential in paintings. In this study, I examine how textiles in their various forms carry the potential to go beyond their normative categorization as decoration. Through a comparative analysis of the paintings produced in two politically distinct polities—Florence and Venice—during the sixteenth century, I integrate Louis Althusser’s theory of ideology and Michael Baxandall’s period eye to elucidate how painted fabric was not the representation of a passive decorative ornament. Rather, it was an active and legible proxy …

Sleep Disturbances In Parkinson’S Patients With A History Of Head Injury, Melissa N. Pacheco

Electronic Theses, Projects, and Dissertations

Sleep disturbances are among the most prevalent and burdensome non-motor symptoms of Parkinson’s disease (PD), yet the contribution of prior traumatic brain injury (TBI) to these problems remains poorly understood. The purpose of this study was to examine whether the number and severity of lifetime head injuries predicted sleep disturbances in individuals with PD. Data from 3,055 PD patients enrolled in the Fox Insight study were analyzed, including 1,593 with a history of head injury. Participants completed self-report questionnaires assessing head injury history, motor and cognitive symptoms, and sleep disturbances. Generalized linear mixed models tested whether head injury history and …

Examining The Effects Of Boundary Management Practices Amongst Remote Workers In A Post-Pandemic World, Rosalia G. Casas

Electronic Theses, Projects, and Dissertations

With remote work on the rise after a world-wide pandemic, boundary management practices have been harder to establish for employees because of the high levels of integration that is seen when working from home. Identifying the impact that boundary management behaviors have on employees is important amongst remote workers because they are more often at risk for work-life spillover and conflict because of permeability between domains. This study looks at the relationship between work arrangements and employee outcomes such as work family conflict and job satisfaction with boundary preference and family supportive supervisor behaviors as moderators. Using linear regression models, …

Beyond The System: A Critical Analysis Of Child Welfare Placement Practices For Children With Autism, Lauren Scott, Nicole Navarro

Electronic Theses, Projects, and Dissertations

Autism Spectrum Disorder (ASD) is a neurological condition that affects an individual’s communication, social interactions, and behavior. Approximately 1.7% of children in the United States are diagnosed with ASD. Families raising children with ASD face significant challenges, including limited support systems, caregiver fatigue, and financial strain. These difficulties increase the likelihood of maltreatment, leading to higher rates of children with ASD being referred to Child Welfare Agencies. Once involved in the system, children with ASD often encounter difficulties in finding appropriate long-term foster or kinship placements, which can result in high rates of placement instability. This research seeks to identify …

Girlhood, Interrupted: An Intersectional Feminist History Of Decolonizing And Reclaiming Womanhood, Ayden Kelly

Electronic Theses, Projects, and Dissertations

In the past few decades, social and political discourse surrounding womanhood and who is considered a "real" woman has led to the execration of transgender women. This work will explore how recent discourse and rhetoric surrounding who is and who is not a “real woman” can be traced to nineteenth century notions of “true womanhood” that excluded women of color. In the late 19th and early 20th centuries, with westward expansion, settler colonialism, residential schools, slavery, and post-emancipation serving as backdrops, this work will also analyze how ideologies of womanhood have interrupted and suppressed women of color throughout Western American …

Seeing And Doing: Disciple-Making And Moral Formation In The Gospel Of John, Stephen Yeagley

Journal of Adventist Youth and Young Adult Ministries

God’s revelation in Jesus Christ both discloses and obligates, presenting an alternate view of reality to be seen and an ethical command to be done. The Gospel of John weaves the motifs of “seeing” and “doing” into a single disciple-making process. It aims to transform a person’s identity, worldview, and understanding of God before inviting ethical emulation. This sequence evokes a moral response, calling disciples to do “just as” Jesus and His Father have done, particularly in love, unity, mission, and otherworldliness. Moral empowerment occurs relationally through a third motif: “dwelling.” Using the metaphors of home, family, and friendship, John …

Divine Attachment As Discipleship: Theology And Practice, Kristina Freed

Journal of Adventist Youth and Young Adult Ministries

Discipleship is more than obedience and behavior management; it is first and foremost a relationship with God. What kind of relationship? Kaufman hinted that it is an attachment relationship, asserting that God is the ultimate attachment figure. Unfortunately, he did not articulate a theology of attachment. While research in the psychology of religion research has shown that God is perceived as an attachment figure and that He engages in attachment behaviors with humans, a theology of attachment has yet to be developed. This paper offers a theology of divine attachment built upon textual and linguistic evidence. I also suggest a …
