Care As Method: Sound, Duration, Relation In Contemporary Art Practice, Violet L. White

MFA in Visual Art

Abstract Care as Method: Sound, Duration, and Multispecies Relation in Contemporary Art Practice

This thesis proposes care as a method of artmaking, not a subject, theme, or aesthetic position, but the actual structural logic through which a body of work is built, sustained, and understood. Working at the intersection of ecological art practice and relational aesthetics, it asks what happens when the encounter at the center of the work is not between two people but between species, infrastructures, and histories of use and what obligations that encounter generates.

The argument is developed through six interconnected works: installations, sound compositions, sculptures, …

Behavioral Science Applications In Collegiate Athlete Nutrition And Sleep: A Scoping Review, Maryam Yuhas, Katherine M. Kidwell, Olivia Moskuna, Rajib Mandal, Jessica L. Garay

Nutrition - All Scholarship

Nutrition and sleep are key health behaviors supporting athletic performance. Collegiate athletes in the United States (U.S.) are at high risk of insufficient dietary intake and nightly sleep given the competing demands of elite sports and academics. Researchers have developed interventions to improve collegiate athletes’ sleep and nutrition, either individually or collectively. However, progress in understanding how best to create sustained behavior change in this population has been slow. This may be due to the lack of application of behavioral science principles such as lack of a guiding theory, effective strategies, and consideration of implementation contexts. This scoping review takes …

Phosphate-Mediated Regulation Of Intracellular Calcium Dynamics, Huma Shahzad, Mohammed S. Razzaque

School of Medicine Publications

Phosphate (Pi) and calcium (Ca2+) are essential mineral ions that play coordinated roles in maintaining normal cellular functions. While various steps of calcium signaling are well characterized, emerging evidence suggests the critical role of both intracellular and extra cellular phosphate in regulating intracellular Ca2+. In the cytoplasm, phosphate influences ATP production and organelle calcium buffering and influences the activity of calcium pumps, such as sarcoplasmic/endoplasmic reticulum Ca2+-ATPase (SERCA) and the plasma membrane Ca2+-ATPase (PMCA). Extracellular phosphate, taken up via sodium-dependent phosphate transporters, triggers signaling cascades that affect the processes of calcium influx, storage, and release. Additionally, high extracellular phosphate levels …

Nitrogen Limitation Adaptation (Nla) Modulates Phosphorus And Iron Homeostasis During Boron Toxicity In Arabidopsis Thaliana, Doğa S. Kayihan, Ümi̇t Bariş Kutman, Emre Aksoy, Ceyhun Kayihan

Turkish Journal of Botany

Boron (B) toxicity is a major abiotic stress factor that impairs plant growth and disrupts nutrient homeostasis. The Nitrogen Limitation Adaptation (NLA) gene has been implicated in nutrient regulation; however, its role under B toxicity remains unclear. In this study, the physiological, biochemical, and nutrient responses of wild-type (Col-0) and nla mutant Arabidopsis thaliana were investigated under mild (1 mM H3 BO3 ; 1B) and severe (2 mM H3 BO3 ; 2B) B toxicity conditions. Excess B reduced fresh weight and photosynthetic pigment levels in both genotypes; however, nla mutants exhibited lower malondialdehyde accumulation under 1B, indicating a delayed oxidative …

The Detection Of Forever Chemicals From Paper Cups Using Colorimetry, Sara Miller

Graduate Student Dissertations, Theses, Capstones, and Portfolios

Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals added to food packaging products to increase water-resistance and durability. PFAS are a growing concern due to their migration into beverages and foods and have been linked to cancer, immunotoxicity, and thyroid disturbances. The purpose of this study was to quantify PFAS migration from paper cups into water and evaluate toxic effects using planarians. PFAS detection was performed using a colorimetric assay, which forms a colored complex with PFAS, on: perfluorononanoic acid (PFNA), heptadeca fluorooctane sulfonic acid potassium salt (PFOS), perfluorooctanoic acid (PFOA). PFNA and PFOS showed absorbance at 640 nm, while …

Distribution, Habitat, And Fish Assemblages Associated With The Rocky Shriner In Arkansas, Savannah L. Wise

ATU Theses and Dissertations 2021 - Present

The Rocky Shiner (Notropis suttkusi) is a minnow species endemic to the Red River and its tributaries in southern Arkansas and Oklahoma. This species is petitioned for listing under the Endangered Species Act and is a species of greatest conservation need (SGCN) in Arkansas. However, there is little information for the species’ distribution, habitat use, and ecological niche, especially within the Arkansas portion of its range. Because of this data gap, my study provides an updated description of its distribution and habitat associations using conditional occupancy modeling and explores patterns of species co-occurrence within the community. I sampled …

Determining Cave Presence And Diet Variation Of The Ozark Big-Eared Bat (Corynorhinus Townsendii Ingens) From Guano Dna, Lark E. Sybrant

ATU Theses and Dissertations 2021 - Present

The Ozark big-eared bat (Corynorhinus townsendii ingens; OBEB) is federally endangered in Arkansas, where it persists in a few small, geographically restricted populations within the Ozark National Forest. Although the region contains many caves that appear suitable for OBEB, expanded survey efforts are needed to locate additional roost sites for monitoring and protection. Effective conservation also requires a clear understanding of their distribution and diet. Traditional cave surveys can be disruptive and often miss cryptic species, and earlier diet studies based on manually sorting prey remains provided only coarse taxonomic resolution and overlooked soft‑bodied insects. To address these …

The Legacy Of Lead: Lead Exposure's Harmful Effects And Its Concentration In Poc Communities, Layla Sophronia Barber

Student Theses 2015-Present

This thesis examines the disproportionate burden of lead exposure carried by low income, POC communities. The systemic nature of this problem is a symptom of a longstanding legacy of environmental injustice in the United States. Decades of federal neglect are reflected in the higher statistics of lead exposure and poisoning in predominantly black communities. While it is understood that lead exposure poses a serious threat to physical health and early cognitive development, there is a discouraging lack of urgency to remove the toxin from non-wealthy communities. The material covered by this thesis aims to identify and correct the discriminatory social …

Associations Between Levels Of Physical Activity And Cognitive Health, Gemma Goldenbaum

Honors Theses

The purpose of this study is to examine the relationship between physical activity levels and executive function, specifically focusing on inhibitory control and working memory capacity. Though the benefits of exercise on brain health are well-documented, the extent of cognitive differences between sedentary individuals and elite student-athletes remains misunderstood. Eighty participants (ages 18–35) were categorized via the International Physical Activity Questionnaire (IPAQ) into sedentary, low, and advanced activity tiers. Participants completed computational assessments, including the Operation Span (OSPAN) task for working memory and Go/No-Go tasks to measure response inhibition and implicit associations. Preliminary results indicated significant differences in sedentary behavior, …

Studying More, Not Less: Rethinking Test Anxiety In Undergraduate Biology Courses, Kailey E. Reeves

Honors Theses

This study investigates the relationships among test anxiety, study behaviors, and metacognitive evaluation in undergraduate biology courses. While prior research has established that study strategies and metacognition influence academic performance, less is known about how these factors interact with test anxiety in undergraduate Biology courses. Guided by the student approaches to learning (SAL) and metacognition frameworks, this study examines whether test anxiety is associated with the type and number of study strategies students use, as well as their ability to evaluate their own learning and preparedness. Using a convergent parallel mixed-methods design, data was collected from 205 students enrolled in …

Evolution Of Nematode Prey Chemotaxis Behavior Across Different Environments, Hailey R. Smith

Honors Theses

Climatic conditions in the near future are projected to be warmer, with more frequent and intense weather events. This will substantially alter the environments in which organisms must integrate specific information to find essential resources. Many organisms rely upon chemical signals to orient towards attractive resources through a mechanism called chemotaxis. How different environmental conditions, like temperature, impact this process will be important to understand as environments change. I conducted a laboratory evolution experiment with the model nematode Caenorhabditis elegans to see how success in chemotaxis assays changes over time when selected under different temperature regimes (normal laboratory temperature, increased …

Mechanisms Underlying Diversity In Bacterial Biofilms, Jacob David Holt

Dartmouth College Ph.D Dissertations

Bacteria commonly exist in natural environments as communities of multiple strains and species attached to surfaces and encased in an extracellular matrix of DNA, protein, and polysaccharides–termed biofilms. These biofilms contribute to diverse functions, from ocean carbon cycling via chitin degradation to pathogenic processes such as wound or implant colonization. The molecular mechanisms governing biofilm formation and composition have been well characterized in model pathogenic organisms, yet the extent to which aspects of biofilm formation contribute to the assembly and maintenance of diverse communities remains less well understood. Using microfluidics, confocal microscopy, and model biofilm-forming bacteria, this thesis details how …

From Stranger To Self: The Role Of Familiarity In Modulating The N170 And N250 Erp Components, Tabish Gul

Dissertations

This study investigated how varying levels of face familiarity modulate the N170 and N250 event-related potential (ERP) components, two neural markers of face perception and recognition. While the N250 is widely considered familiarity-sensitive, the N170 has traditionally been linked to the structural encoding stage of face perception. However, recent research suggests that face familiarity may also influence N170 amplitude and latency. While most previous studies have compared up to three familiarity levels, the present study examined five levels of familiarity: own face, friend’s face, famous face, experimentally familiar face, and unfamiliar face. Twenty-six participants viewed face images while completing a …

Brachial Macroparasite Loads In Estuarine Young-Of-Year Striped Mullet (Mugil Cephalus), Triston Rice

Honors Theses

Climate change is a growing threat to marine habitats globally. One ecological impact that warming water temperatures poses is the increased metabolic rate of many parasite species. Their promoted reproductive and feeding rates could pose a threat to the stability of many host populations. Parasites of the gills, or brachial parasites, are especially concerning to fish populations globally. As parasitism is not limited to a specific taxon and comprises a large diversity of ecomorphs and behaviors, geographically distinct areas may be differentially affected by the changing prevalence of parasites. This study aimed to survey current brachial parasite abundance and prevalence …

Neuroprotective Effects Of Estradiol And Genistein And Interactions With Aromatase Inhibitions Post Cerebellar Lesion In Male Zebra Finches, Grace E. Thompson, Anthony P. Irovic

Honors Theses

Across vertebrates, peripheral and brain-derived estradiol (E₂) promotes neuroplasticity. After injury, E₂ can be derived locally from testosterone via aromatase (AROM), an enzyme that is upregulated in glia at the site of neural injury. E₂disrupts testicular function and elevates cancer and stroke risk, primarily via binding to estrogen receptor alpha (ER α). Genistein (GEN), a phytoestrogen, is similar to E₂ but binds preferentially to estrogen receptor beta (ER β). It may offer neuroprotection without adverse effects of E₂. We used adult male zebra finches (ZF) to model neuroprotective effects of E_{2 …}

Community Composition Of Antibiotic-Resistant Bacteria On The Mississippi Gulf Coast, Marisa Martin, Colin Jackson

Honors Theses

The Mississippi Gulf Coast is an important resource for transportation, economic development, and recreation. Given its economic and cultural importance, it is crucial to maintain clean and safe conditions along the coast for public health, but other than routine beach monitoring, few studies have examined microbial contamination of coastal waters in this region. This study aimed to determine the quantity, composition, and distribution of bacteria resistant to six different antibiotics (Vancomycin, Kanamycin, Tetracycline, Ciprofloxacin, Erythromycin, or Amoxicillin) in seawater at seven public beaches along the Mississippi Gulf Coast. No bacteria resistant to Ciprofloxacin were detected, and bacteria resistant to Kanamycin …

Unc-45b As A Potential Chaperone For The Transcription Factor, Gata-4, Kaylah Owings

Electronic Theses and Dissertations

The cardiac myosin–specific chaperone UNC-45B has been shown to physically interact with the cardiac myosin transcription factor GATA-4. Specifically, this interaction occurs within the chaperoning region of UNC-45B, known as the UCS domain. However, the precise nature of this interaction has not yet been fully elucidated. The present study was conducted to confirm earlier findings and to evaluate whether UNC-45B functions as a chaperone for GATA-4 using bioinformatic approaches. Analysis of the interaction using AlphaFold 3 modeling verified not only that binding occurs at the UCS (chaperoning) domain of UNC-45B, but also that the interaction is associated with an increase …

Rowan-Virtua Research Day

Title: Atomoxetine enhances specific dimensions of cognitive performance in a rodent strategy shifting assay

Authors: Jessica Ivanov, Christopher P. Knapp, Barry D. Waterhouse, Rachel L. Navarra

Objective: Cognitive flexibility, a domain of executive function, supports adaptive shifts in behavior in response to changing environmental demands and task contingencies. Deficits in this capacity are common to neuropsychiatric disorders such as Attention Deficit Hyperactivity Disorder (ADHD), where improper regulation of the catecholamine transmitters dopamine (DA) and norepinephrine (NE) within the prefrontal cortex (PFC) has been implicated. Atomoxetine (ATX), a selective NE transporter (NET) inhibitor, elevates levels of NE and DA in the …

Optimization Of Refolding, Purification, And Analytical Characterization Of Proinsulin(F25d) Soluble Antigen Array Immunotherapy, Abigail Richardson

McKelvey School of Engineering Graduate Student Theses & Dissertations

Type 1 Diabetes (T1D) is characterized by autoreactive immune responses to insulin and its precursor, proinsulin. Soluble antigen arrays (SAgAs) displaying the metabolically inactive proinsulin variant, proinsulin(F25D), represent a promising antigen‑specific immunotherapy candidate for T1D. However, the production of these platforms is hindered by substantial practical challenges, including protein aggregation, inefficient refolding, and the lack of sensitive analytical tools to verify quality and dosage. This work establishes an integrated, scalable pipeline for the purification, conjugation, and quantification of a proinsulin(F25D) SAgA. First, we optimized the refolding of recombinant methionine-proinsulin(F25D) (M-PI(F25D)) from inclusion bodies using controlled buffer systems and created a …
