Mechanisms Of Sleep Regulation In Drosophila Melanogaster, Anfal A. Abuhilal

Dissertations, Theses, and Capstone Projects

Sleep is a fundamental biological need, and sufficient sleep is required for physical and mental well-being. Sleep is regulated by two biological mechanisms: sleep-wake homeostasis and circadian rhythm. Circadian rhythms are near 24-h rhythms in behavior and physiology that are generated by endogenous mechanisms. In mammals, the suprachiasmatic nucleus (SCN) is the central circadian pacemaker, which is known to receive a significant amount of serotonergic input that likely modulates sleep rhythms. In addition to circadian modulation, sleep is subject to homeostatic regulation. Several neuromodulators have been proposed as mediators of sleep homeostasis. Serotonin has been implicated in sleep drive and …

Wavelength And Luminance Interaction On Spatio-Temporal Contrast Sensitivity Function, Taylan S. Ergun

Dissertations, Theses, and Capstone Projects

Contrast sensitivity (CS) measures the ability to discriminate objects from their backgrounds under varying conditions(Campbell & Robson, 1968). Contrast sensitivity is important for navigating the real world and operating under different light conditions. The contrast sensitivity function (CSF) reflects how the visual system performs under different conditions. This measure is crucial in assessing the health of the visual system (Chen & Gardner, 2021). CSF contributes to a deeper understanding of how the visual system processes and integrates properties of light to create visual sensation and perception. Human contrast sensitivity depends on the viewing conditions such as field size, luminance, color, …

The Role Of Water In Peptide Behavior And Peptide-Based Water-Responsive Crystals, Janel Jannette Rivera Cancel

Dissertations, Theses, and Capstone Projects

Water plays a crucial role in shaping the behavior and function of biomolecules across the liquid, supercooled, and glassy states. This thesis presents a dual approach combining computational simulations and experimental investigations to explore the influence of water on biomolecular systems, particularly peptide-based materials. We employ molecular dynamics simulations to study the hydration-dependent structural dynamics of homopolymer peptides. Simulations were carried out across a range of temperatures and pressures to analyze changes in hydration and structural stability, shedding light on the behavior of peptides under supercooled and glassy conditions. These studies are especially relevant for understanding biomolecular stability in cryopreservation. …

Structural Characterization Of A Tarantula Toxin And Its Interactions With Lipid Bilayers And Voltage-Gated Sodium Channels, Krishnakoli Adhikary

Dissertations, Theses, and Capstone Projects

Voltage-gated ion channels are membrane protein complexes. They allow the selective flow of their respective ions down an electrochemical gradient through a central ion conduction pore surrounded by four voltage-sensing domains (VSDs). Various neurological and cardiovascular diseases are caused by mutations in voltage-gated ion channels (VGICs). One of the biggest challenges today is addiction to opioid medication. Coming up with non-opioid drug leads can be a real blessing for society. This is where voltage-gated sodium channel research comes in. Na_v1.7, Na_v1.8, and Na_v1.9 are responsible for pain sensations. Loss or gain of function in …

Improving The Assessment Of Functional Ability In Older Adults, Aneela Rahman

Dissertations, Theses, and Capstone Projects

Deficits in instrumental activities of daily living (IADL) are a hallmark of dementia, and the unprecedented aging of the population strongly motivates early identification of older adults at-risk for functional decline. In 2015, the White House Conference on Aging emphasized the need to improve detection of diminished capacity across important areas of functioning. To date, there is very limited research on early IADL changes in cognitively unimpaired (CU) individuals and those with subjective cognitive decline (SCD) and mild cognitive impairment (MCI), who may be in early preclinical dementia stages. Additionally, little is known about how changes in functional brain networks …

Tradition, Individuality, And Innovation In Western Classical Music Performance: A Quantitative Analysis Of Bach’S Fourth Cello Suite Prelude, Clare Monfredo

Dissertations, Theses, and Capstone Projects

Why do we seek out new performances of a commonly performed piece of music? An essential tradition of Western classical music (WCM) is the performance of canonical works by composers, an activity that requires the interpretation and execution of written scores by individual performers. In this practice, performers are not only expected to determine the composer’s “intentions,” but also somehow (paradoxically) share these in a “unique” performance interpretation. In musical education, performers are trained by teachers to create these “unique” interpretations by learning how to intuit composers’ intentions in a system that passes down interpretative traditions through master-apprentice one-on-one lessons. …

Nocturnal Foraging By Great Blue Heron (Ardea Herodias) And Roseate Spoonbill (Platalea Ajaja), Laura E. Josler, Johnny E. Owens, Sarrah E. Bristol, Leo N. Dutkewych, Abigail R. Kauke, Signe E. Renstrom, Ben G. Sheffield, Madelyne E. Vashaw, Avery J. Nesbitt, Melia K. Paat, Timothy D. Bransford, Elizabeth A. Forys

Florida Field Naturalist

The Great Blue Heron (Ardea herodias) and Roseate Spoonbill (Platalea ajaja) are long-legged wading birds that can forage throughout a 24-hour cycle. Nocturnal foraging enables these species to take advantage of optimal foraging conditions and reduced competition. This study aims to investigate how environmental factors influence the nocturnal foraging behavior of these species. To monitor foraging activity, we deployed 17-18 infrared cameras from dusk until dawn from 4 October 2023 to 24 July 24 2024, covering two sampling periods across different habitats within Fort De Soto County Park, a barrier island complex in Tampa Bay, Florida. We compared the frequency …

“Lead”Ing Industrial Science: Studying Occupational Lead Poisoning In The Early 20th Century, Rebekah E. Dreyer-Rowe

Master's Theses and Capstones

Lead was essential to the creation and coalescence of industrial hygiene as a discipline in the United States from its early days in the 1910s through the 1930s when the first professional associations of industrial hygiene were formed. In the early years, Alice Hamilton was central to the burgeoning field, and her seminal study on lead poisoning in Illinois industries thrust both her and her methods into the spotlight. Industrial hygienists of her generation followed her methods and came away with similar conclusions: that occupational diseases were rampant in the US, even if few people were studying them. In the …

Indigenous Women’S Reproductive Traditions: Reclaiming Sovereignty Through 500 Years Of Colonization, Stephanie A. Sellers

Gettysburg College Faculty Books

In Indigenous Women’s Reproductive Traditions, Stephanie Sellers delves into the rich history of Indigenous women’s reproductive practices before European colonization. The book highlights traditional methods such as birth control, abortion, and child spacing, which were integral to maintaining agency over their bodies. Sellers explores how these practices were disrupted by European patriarchal structures and examines the impact of forced sterilization in the 20th century. Today, Indigenous women are reclaiming their rights through movements for reproductive justice, advocating for a return to their ancestral practices and redefining concepts of womanhood and motherhood on their own tribal terms.

Cardiovascular And Aortic Wave Reflection Responses To Evening Binge Alcohol Consumption, Grant Thivierge, Ian Greenlund, Jeremy Bigalke, Carl Smoot, Jason R. Carter, John J. Durocher

Michigan Tech Publications

Evening binge alcohol consumption contributes to sleep disruption and autonomic dysregulation that persists into the following morning. However, its impact on morning-after arterial stiffness and aortic wave reflection remains unknown. Using a randomized, crossover, fluid-controlled design, we hypothesized that heart rate (HR), carotid-femoral pulse wave velocity (cfPWV), aortic augmentation index (AIx), and aortic pulsatile load (APL) would be increased acutely after binge drinking at night (study 1) and the morning-after binge drinking (study 2). Participants (n=33, 18 females, 15 males, age 25±1 years, BMI: 27±1 kg/m) completed binge alcohol (4-5 drink equivalent) and fluid control protocols. Study 1 examined cardiovascular …

Labor Productivity Losses Across Construction Trades: A Machine Learning Approach, Tamima Elbashbishy, Islam H. El-Adaway

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Labor productivity is a major concern in the construction industry. Existing research on construction labor productivity (CLP) within specific trades has produced inconsistent findings due to differences in the factors analyzed. This lack of consistency makes it difficult to identify the most critical drivers of productivity losses across trades. To address this gap, this study adopts a cross-trade analytical approach to systematically identify and evaluate the inefficiencies impacting labor productivity in multiple construction trades. Specifically, the study (1) identified common organizational and project-level inefficiencies that influence labor performance; (2) conducted an expert-based survey to measure the frequency and perceived impact …

A Mobility Data-Driven Approach To Analyzing And Modeling Park Accessibility Inequities And Use In U.S. Cities, Michaelmary Chukwu

Graduate Theses and Dissertations

Urban Park accessibility inequities have been a longstanding issue globally and the United States in particular. Despite the benefits that urban parks provide, use and access is not equitably distributed among the population, often favoring historically privileged populations over others (disadvantaged). Fortunately, improvements have been made in recent years to promote balanced park distribution in some cities; however, evidence still shows that most cities are behind. Interestingly, the rise in human mobility data has facilitated the study of human behavior and use of activity spaces. This thesis advances the existing studies on park accessibility and emerging human mobility to study …

Helping Someone Off The Hook: Post-Moral Disengagement As An Interpersonal Emotion Regulation Strategy In A Hypothetical Alcohol-Involved Sexual Assault Vignette, Kayla Ford

Graduate Theses and Dissertations

Post-moral disengagement (PMD) is posited as a form of interpersonal emotion regulation that involves altering the severity of harmful conduct and/or the transgressor’s personal responsibility to facilitate avoidance of negative emotions like guilt, which could maintain problematic behaviors. A pervasive harmful behavior on college campuses is alcohol-involved sexual violence, wherein intoxication is often used as an excuse or justification for assault. Though some aggressors of sexual violence experience guilt afterwards, it is unclear how bystanders might respond to this display of emotion and the potential applicability of PMD. As an initial step to assessing PMD as interpersonal emotion regulation, the …

Sound Decisions: The Impact Of Music Genre In Fashion Advertising On Consumer Perceptions And Purchase Intention, Cassandra Thomas

Graduate Theses and Dissertations

This study examines how music genre, brand type, and the perceived congruency between the two influences consumer perceptions of fashion advertising. Guided by Congruity Theory and Attitude Theory, this study employed a 3x3 experimental design in which 252 participants viewed one of nine advertisement conditions varying by music genre (pop, hip-hop, electronic) and brand type (activewear, fast fashion, luxury). A series of one-way ANOVAs, bivariate correlations, and regression analyses were conducted to interpret the effects of music genre, brand type, and perceived congruency on attitudes toward 1) the advertisement and brand, 2) credibility of the advertisement and brand, and 3) …

A Security Worth Having: The Pursuit Of Happiness Through Reading Burney, Radcliffe, And Austen, Samantha Meeks

Graduate Theses and Dissertations

This dissertation explores the works of three female authors of female protagonists in the long 18th century: Frances Burney’s Camilla and Evelina; Anne Radcliffe’s The Mysteries of Udolpho and The Italian; and Jane Austen’s Northanger Abbey, Sense and Sensibility, and Pride and Prejudice. By following the paths to security the female protagonists of these novels fashion, and identifying the elements of Stoicism and related Hellenism and the aspects of cybernetics, this dissertation delves into the choices female protagonists make along the way regarding their security and how such choices lead to agency and self-fashioning for these women. Emotional, economic, and …
