A Machine Learning Framework For Early-Stage Cost Estimation Of Transportation Projects, Pritom Paul

Electronic Theses and Dissertations

To address the limitations of traditional planning-level cost estimating methods, such as reliance on statewide averages, heavy reliance on engineering judgment, and high levels of inaccuracy, this study developed two data-driven frameworks and corresponding tools. The first framework focused on resurfacing projects and used treatment-specific simple linear regression based on lane miles and geographic location. The second addressed a broader group of construction projects and used multiple linear regression with project length, route type, and right-of-way cost as key predictors. In both frameworks, the final estimates are computed by aggregating multiple estimates produced by county-, region-, and state-level models. The …

The Impact Of Traditional Machismo On Mental Health Outcomes: Depression And Suicide Risk Among Latino Immigrant And Non-Immigrant Men, Yesenia A, Romero

Electronic Theses and Dissertations

Traditional masculine norms have long been recognized as influential factors in men’s psychological well-being. Within Latino cultures, the construct of machismo represents a culturally specific form of masculinity characterized by ideals of masculinity and characterized by ideals of strength, dominance, and emotional restraint. While these norms may promote resilience and family responsibilities, rigid adherence to traditional machismo has also been associated with emotional suppression, reduced help-seeking behaviors, and increased psychological distress. The present study conducted a meta-analysis to examine the relationship between traditional machismo and mental health outcomes among Latino men, with particular attention to depressive symptoms as well as …

Reading The Wisdom Of Psalm 37 Through The Lens Of Metaphor And Lament, Hannah N. Johanson

Electronic Theses and Dissertations

This thesis proposes that reading Ps 37 through the lens of both metaphor and lament can reshape the way the reader understands the reality of evil, fostering hope and agency. While Ps 37 is often classified as a wisdom psalm, this thesis diverges from the interpretation that this psalm is a list of proverbs. Instead, this thesis attempts to show that Ps 37 forms a metaphorical landscape where evil withers, vanishes, and is cut off while goodness thrives and is secured forever. This thesis also places this psalm in dialogue with two poems that engage Ps 37 from a post-Shoah …

Post-Exercise Vitals Recovery Response In Barrel Horses: A Field Study On Cooling Methods Used By Competitors, Lauran E. Hetrick

Electronic Theses and Dissertations

Barrel racing demands peak physical performance from equine athletes, yet limited research evaluates the field-based strategies used to optimize equine recovery at competition. This study assessed recovery management approaches used by competitors to elucidate their influence of physiological recovery by measuring heart rate, respiratory rate, and body temperature during a high-profile barrel race competition. Physiological data were collected at baseline, immediately post-exercise, and during a 15–30-minute cooldown period to characterize recovery under real-world conditions. Significant increases in HR, RR, and BT occurred from baseline to post-run (p < 0.001), followed by reductions during cooldown (p < 0.01), though values remained elevated (p < 0.05). Rinsing reduced HR and RR (p < 0.01), while shade and fans decreased RR and variably influenced HR. Noise, as a confounding variable, decreased HR but increased BT (p < 0.001). Ultimately, these results emphasize multimodal recovery approaches in competitive equine management in the field.

Bass And Drum Grooves In R&B: Analysis And Composition, Hugh Taylor

Electronic Theses and Dissertations

The term “R&B” has existed within the musical lexicon for nearly eighty years. It was first introduced in 1949 to replace the label “race music,” and was a combination of blues, jazz, gospel, and rock. Since then, the genre has transitioned from swing-based, live instrumentation toward straight-eighth backbeats and electronically produced sounds. Despite these shifts, contemporary R&B continues to borrow from its ancestral roots while maintaining a modern aesthetic. A primary feature that has persisted through this landscape is the “groove,” specifically defined here as the rhythmic layer created by the drums and bass. In R&B, the bass provides both …

Attendance Matters: Incentive Programs And Chronic Absenteeism In Elementary Schools, Aubryn Street

Electronic Theses and Dissertations

Chronic absenteeism is a common challenge in elementary education. Schools often use attendance incentive programs, such as rewards or recognition, to encourage students to attend regularly. However, it is not always clear whether these programs actually improve attendance. This study examined whether attendance incentive programs are effective and how school staff view and use these programs.

This mixed-methods study used both school attendance data and interviews with school personnel. Attendance data from two school years showed that schools with incentive programs did not have lower absenteeism rates than schools without them. However, attendance improved overall from one year to the …

Bergsonian Blend: Subjective Temporality Within Modernist Aesthetics Of Mental Illness, Lydia Victoria Gervais

Electronic Theses and Dissertations

Henri Bergson was a modernist French philosopher who wrote extensively on the topic of the lived experience of time, which he called durée, or duration. His contemporary, Sigmund Freud, was developing psychoanalytic theory in a growing field of psychological study, which serves as a prominent ancestor to modern psychiatry and current psychoanalytical literary studies. Fiction writers of the 1900s absorbed the zeitgeist of melded chronology and consciousness, interweaving themes of time and trauma in their works. Utilizing Henri Bergson’s durée as a philosophical framework, I examine the moralization of time-consciousness in connection with mental illness and investigate representations of …

Stability Of Paraffin-Insulated Nitrogen-Doped Carbon Fiber Ultramicroelectrodes, Maxwell H. Kwakwah

Electronic Theses and Dissertations

Nitrogen-doped carbon materials can facilitate the reduction oxygen-oxygen bonds, a key step in electroreduction of both O₂ (an important reaction in energy applications) and H₂O₂ (an important reaction in sensing and biosensing). Our lab previously demonstrated that thermal decomposition of urea in the presence of carbon fiber (CF) results in an N-doped carbon material that exhibits good electrocatalytic properties for H₂O₂ reduction. However, previous methods of insulating single N-doped CF via laser heating of borosilicate capillaries and epoxy to prepare ultramicroelectrodes (UMEs) seemed to adversely affect surface nitrogen contents and electrocatalytic properties. More recent work that utilized paraffin to …

Discrete-Event Simulation: A Leslie System Model For Transportation Demography, Md Zobaer Ahammad

Electronic Theses and Dissertations

Transportation systems are influenced by demographic change, household formation,and patterns of vehicle ownership. These factors affect long-run transportation demand and congestion levels within urban infrastructure. Understanding how demographic dynamics interact with transportation behavior is therefore important for analyzing the long-term evolution of transportation systems. This thesis develops a modeling framework that integrates discrete-event simulation with a Leslie-type matrix model to study transportation–demography interactions.Simulation outputs are aggregated to construct a transition matrix describing changes in transportation states. This matrix acts as a linear (or affine) transformation on the transportation state vector, allowing the system to be analyzed as a discrete linear …
