The Impact Of Screen Time Patterns On Digital Behaviour And Productivity: A Data Analytics Study Across Age Groups, Maytha Alshamsi

Theses

The increasing incidence of screen time of all ages has generated a greater interest in the effect of screens on the human psyche. This paper looks at behavioural data of 2, 000 individuals aged 13-64 to investigate the predictability of a composite mental- health score by various modalities of screen-time, lifestyle and psychological charac- teristics. We determine, based on exploratory statistics, multivariate regression and su- pervised machine-learned models, that in as much as the influence of total screen time and social-media consumption has significant relationships with worse mental health, the effects are small when juxtaposed to those of lifestyle and …

Assessing A Model Of Customer Rage: Does Customer Entitlement Moderate Relationships Between Rage Emotions, Expressions And Behaviors?, S. Mostafa Rasoolimanesh, Martin Gannon, Babak Taheri, Josip Mikulić

Research outputs 2022 to 2026

Across travel and tourism services research, studies investigating “customer rage” typically prioritize the direct point-of-consumption, often within airport, airline, or hotel contexts. However, the sector is awash with intermediaries (e.g., travel agencies, insurance brokers, booking platforms), which serve as primary points-of-contact capable of shaping customer expectations. Accordingly, the consequences of service failure therein are nuanced and complex. Yet, extant research often portrays service failure as unilateral (i.e., solely the firm in question’s responsibility), overlooking one core demand-side characteristic: the customer’s sense of entitlement. Thus, while this study draws upon the Iranian travel agency setting (as a service intermediary) to assess …

Honoring Philip Zimbardo: Personal Reflections On A Legacy In Heroism Studies, Zeno Franco, Scott T. Allison, Brian R. Riches

Heroism Science

This article concludes our Special Issue of Heroism Science devoted to honoring the legacy of Philip Zimbardo. Across the preceding contributions, scholars have offered personal reflections, examined his influence on psychology and heroism studies, and discussed the applied interventions of the Heroic Imagination Project. In this closing essay, we situate Zimbardo’s distinctive contributions to psychology and reflect on the cumulative insights of the Special Issue. We then shift to a more personal register, as each of the three authors describes how Zimbardo’s mentorship, vision, personality, and scholarship have shaped our own lives and research trajectories. In doing so, we underscore …

Pediatric Anesthesia And Virtual Reality: Managing Perioperative Pain And Anxiety– A Scoping Review, Moneer Sharafi, Mason Pham, Alec Wiscombe

Doctoral Projects

Pediatric surgery is common, but it often causes considerable anxiety and pain. A staggering percentage of children experience preoperative anxiety, which can heighten pain, delay recovery, and contribute to complications such as emergence delirium and longer-term behavioral issues (Fortier & Kain, 2015). Virtual reality (VR), which immerses users in computer-generated environments, has been proposed as a distraction technique to reduce these challenges. This Doctor of Nursing Practice (DNP) project conducted a scoping review to examine the effectiveness of VR in reducing perioperative pain and anxiety in pediatric patients. The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses …

Behind The Badge: Effects Of Stress And Trauma In Policing -- Understanding The Importance Of Evidence-Based Prevention, Early Intervention, And Wellness Programs, Jessica Rolshouse

Master of Arts in Human Services

Law enforcement officers are exposed to occupational stress and trauma routinely and at rates that far exceed the general population. This chronic exposure places them at risk for physical and psychological injury and negative outcomes to include mental health disorders including burnout, anxiety, depression, and PTSD. Prolonged exposure to occupational stress and trauma also increases the risk of suicidal ideation and dying by suicide, the most tragic outcome of the stress law enforcement officers face. This literature review focuses on individual risk factors, occupational stress, and trauma, and the development of mental health disorders in law enforcement officers. It also …

The Sexual Assault And Violence Experiences Questionnaire: Community-Developed Items For Gathering Sexual Violence Histories With Displaced Women, Meredith A. Blackwell

Psychology ETDs

Improving measurement of sexual violence has contributed to major policy changes in the United States. However, research on sexual violence largely overlooks those exposed to conflict and displacement: a population especially at risk. Assessment measures often ignore contextual features and use phrasing that is vulnerable to underreporting. This community-based participatory research project collaborated with cultural experts from Mexico/Central America and Afghanistan to develop a preliminary item list for a self-report measure of prior sexual violence. Analysis of focus group data from 30 women revealed a range of sexual violence experiences, and provided critical phrasing used to form an item list …

Investigating Teacher Perceptions Of Strategies That Led To Success Of Long-Term English Learners Passing English Assessment Exams, Whitney Hodges

Ed.D. Dissertations

Long term English learners are those who have been enrolled in United States public schools for at least five to seven years yet have not exited language services via passing scores on language assessments. Those students have less opportunity to take preferred elective courses in middle and high school, and less opportunity to take higher level course work. This impacted the students, teachers, and instructional leaders when it came to scheduling, fulfilling graduation requirements, and meeting schoolwide and statewide growth and achievement goals. Previous researchers provided strategies for helping newcomers learn a language, and move from basic interpersonal communication skills …

Stress During Adolescence: A Characterization Of Anxiety-Like Behavior, And The Mrna Expression Of Neuroimmune Factors, Clock And Stress Genes In Corticolimbic Areas., Annette Fernandez Oropeza, Annette K. Fernandez Oropeza

Biomedical Sciences ETDs

Adolescence represents a critical window of frontal cortex (FC) maturation and corticolimbic circuit refinement that supports stress and emotion regulation. Disruption of these processes by early-life insults such as prenatal alcohol exposure (PAE) or adolescent stress increases vulnerability to anxiety and mood disorders, in part through circadian–immune dysregulation. The circadian transcription factor Bmal1 and the proinflammatory cytokine tumor necrosis factor-alpha (TNFα) have emerged as key regulators of neuroimmune signaling and synaptic communication, yet their interactions across developmental risk contexts remain poorly understood. This dissertation examined the effects of mild adolescent isolation stress, with and without PAE, on anxiety-like behaviors and …

The Role Of Multimodal Analgesia In Spine Surgery: A Scoping Review Of Its Impact On Opioid Consumption And Surgical Outcomes, Madison Milam, Kristie Mullins, Tatum Trent

Doctoral Projects

The ongoing opioid epidemic emphasizes the need for alternative perioperative pain management strategies, particularly in high-risk surgical populations such as spine surgery patients. This project proposes a scoping review to examine the role of multimodal analgesia (MMA) in reducing opioid consumption and improving surgical outcomes in adult neurosurgical patients. MMA analgesia involves the use of multiple pharmacologic and nonpharmacologic approaches that target different pain pathways in the human body, aiming to enhance patient comfort while minimizing reliance on opioids.

This review synthesizes current literature on MMA strategies used in spinal surgeries, evaluates reported outcomes such as pain control, postoperative complications, …

Neurobehavioral Mechanisms Of Psychotic-Like Experiences And Cannabis Use, Ethan Campbell

Psychology ETDs

As cannabis use has increased steadily over the past decade, there is critical need to evaluate early cannabis use as a potential risk factor for the development of psychosis. Neurobehavioral mechanisms underlying novelty salience could clarify how cannabis exposure may influence subclinical psychotic-like experiences (PLEs). The present study leveraged dynamic functional connectivity and task-fMRI to assess the role of novelty processing in cannabis use and PLEs. A group of brain regions dynamically tied to the salience network while viewing short films were found to increase their activation as a function of stimulus novelty during a novelty bandit task. PLEs were …

Testing Tocqueville’S Troops: American Democracy At War In Mexico, Corbin V. Cali

History Theses

This thesis explores Alexis de Tocqueville's theory of democratic armies through the lens of the Mexican-American War (1846-1848), testing his predictions about how democratic social conditions influence military institutions and performance. Tocqueville argued that armies in democratic societies would face tensions between egalitarian ideals and military discipline, with citizen-soldiers resisting hierarchy while professional officers, often isolated from civil society, grew dangerously ambitious for war. He predicted that democratic armies would show energetic initiative but struggle with weak formal discipline, and that equality would fundamentally change the relationship between the military and the broader society. The Mexican-American War serves as an …

Sue Gunter And The Battle For Equity In Women’S Athletics At Sfa, Derek S. Allen

Electronic Theses and Dissertations

From the 1950’s through the 2000’s, women’s college basketball would move from a category of inappropriate activity to selling out large arenas and being broadcast to millions of viewers on national TV. Such a result came largely from federally mandated stipulation contained within Title IX, accelerated a fight for equity and acceptance, and advanced the cause for women’s athletics more than any other initiative. However, that alone would have failed to grow the popularity of a sport such as women’s basketball if it did not produce a quality product for fans. Beyond the need for resources comparable to men’s athletics, …

Instrumental Music Educator Strategies To Reduce Or Remove Participation Barriers For Middle School Students, Rachel A. Gorden Mercer Ed.D

Doctorate in Education

Knowledge Production As Identity Expression: A Third-Space Perspective On Sustainable Careers, Alicja Syska

School of Law, Humanities and Social Sciences

This conceptual paper advances our understanding of sustainable careers by focusing on the knowledge creation activities of third-space practitioners in higher education. Specifically, we apply and extend the Process Model of Sustainable Careers to examine how different forms of knowledge production in three different institutional and national contexts – writing for publication, practice-based expertise, and curriculum development – contribute to career sustainability at the intersection of academic and professional/administrative roles and domains. The critical element of this extension is ‘identity expression’ in the form of knowledge production, which acts as an integrating mechanism that flows through and connects the original …

Speaking Up Or Helping Out? The Impact Of Gendered Feedback On Voice And Helping Ocbs And Imposter Phenomenon And Self-Confidence, Jacklyn Scymcyk

Theses and Dissertations

Grounded in Self-Discrepancy Theory (Higgins, 1987) and Role Congruity Theory (Eagly & Karau, 2002), this study examines how gendered differences in feedback influence employees’ self-views and subsequent citizenship behaviors. Specifically, the research aimed to investigate how the relative frequency of task performance feedback and contextual performance feedback impacts self-confidence and imposter phenomenon, and how these self-views, in turn, predict voice and helping organizational citizenship behaviors (OCBs), respectively. Initial phases of this study validated measures for perceptions of task and contextual performance feedback frequency, favorability, and adequacy. The final phase used moderated-mediation polynomial regression analyses to test hypotheses. Exploratory cluster …

Recreating Fiber Recruitment With Fiber Recruitment Using Additive Manufacturing, Natalia D. Mciver

Biomedical Engineering ETDs

Injured ligaments are often repaired with tendon grafts which may over or under constrain the joint; there is a need for an artificial graft option with the mechanical properties of a native ligament. Crimped fibers within ligaments allow for recruitment which means the viscoelastic properties of stress relaxation and creep are not inversely related. A feasibility study using ACLs and large-scale crimp models to study viscoelasticity, led to an in-depth analysis of the scapholunate interosseous ligament. Using the Modified Kelvin spring-dashpot model, for describing viscoelasticity with a variable stiffness property (time dependent fiber recruitment), we defined the relationship between creep …

How To Talk To A Seahorse: Communication In Transmasculine Gestational Experiences As Told Through Narrative, Emerson Armstrong

Communication ETDs

Transmasculine experiences before, during, and after pregnancy were evaluated using focus groups and autoethnographic research. As transgender people are more likely to experience inequality in healthcare encounters, this project aims to shed light on, and counter sensationalized accounts of male pregnancy, as transmasculine gestational individuals sought normalization in their experiences of pregnancy. Seven focus groups consisted of 90 minute sessions, with a total of 15 participants. Transcripts were analyzed using a trans narrative approach to find a greater understanding about identity construction, challenges, and changes around trans pregnancy. Asking about communities and healthcare experiences worked to create a complete picture …
