Comparative Analysis Of Rhizosphere And Endosphere Microbiome Of Different Blueberry Species (Vaccinium Sp.), Niladri Bhowmik

Master's Theses

Blueberries are an important agricultural commodity in all over the United States. Due to its health benefits, there is a huge demand globally, thus expanding the industry. Breeding programs are essential to maintain such industries. Challenges that play a role in contemporary breeding programs are various biotic and abiotic stress factors. Studies have shown that microorganisms are recruited by plants to alleviate them during stressful conditions. Though blueberries have been cultivated for about 100 years, how the microbiome has been affected due to this is poorly understood. We hypothesized that interspecific crosses and artificial selection have significantly changed the microbiome …

The Effect Of Cannabinoids And Terpenes On The Activation Of Hmc3 Microglial Cells, Mohamed Marzouk

Honors Theses

Life expectancies of people living with HIV have significantly lengthened due to the availability of antiretroviral therapies. Despite their ability to increase survival, these treatments do not “cure” HIV, nor do the stop the onset of neurological symptoms associated with infection, termed neuroHIV. NeuroHIV describes a myriad of neurological impairments including mood disorders (depression and anxiety), cognitive impairment, neuropathic pain, and motor disinhibition that reduce quality of life for people living with HIV. Mechanistically, the neurological impairments may involve actions of neurotoxic proteins directly produced by the virus. One of these proteins that has been well-characterized is the HIV trans …

The Opioid Epidemic: How Genetics Play A Role In Addiction And Treatment, Kirsten Houston

Honors College Theses

The opioid epidemic is an issue within the pharmaceutical industry in the United States of America due to prescription and non-prescription substances being made available to the population. Opioids include chemical substances that affect the body and brain through opioid receptors, including the mu, kappa, and delta receptors. These substances are derived and synthesized from the poppy plant. Multiple causes have been linked to opioid abuse disorder, including but not limited to employment, income, housing, nutrition, mental health disorders, and genetics. By gathering information from previous literature, genetics may be the main cause of narcotic analgesic tolerance and abuse. Specific …

Cenabis Bene: A Culinary Odyssey Through Apicius, Kathryn Atkinson

Honors Scholar Theses

Apicius is the sole surviving cookbook from classical antiquity; as such it is invaluable for what it tells us about ancient feasting customs. Yet the gluttony typically associated with classical antiquity has no place in Apicius beyond the art that is inherently associated with food; we are not so much given a seat at the cena (dinner) as we are led into the kitchen, handed an apron, and instructed to cook. This critical analysis explores each recipe not only on the surface—i.e., examining the ingredients and recreating selected recipes—but also on a deeper level, lifting food above its concrete reality …

Assessing Word Recognition In Infants With A History Of Chronic Otitis Media, Sarah Wright

Dissertations, 2020-current

Otitis media (OM) is a common ear-related disorder diagnosed in children that can cause a temporary conductive hearing loss. The fluctuating hearing loss may alter auditory processing which may interfere with language development while impacting quality of life for infants and their caregivers (Homøe et al., 2019). In several languages, eleven-month-old infants have shown a preference for familiar words over unfamiliar words using the head-turn preference paradigm. This study examines the effect of chronic OM on the preference for familiar or unfamiliar words in eleven-month-old infants. Fourteen eleven-month-old infants (mean age 344 days) with three or more diagnosed ear infections …

Locomotion And Life History In A Leaping Primate: Mechanics And Energetics Of Movement Throughout The Propithecus Lifespan, Nicholas Heslep

Masters Theses, 2020-current

Arboreal primates are typically altricial, exhibit long juvenile periods, and use dynamic locomotor behaviors that can be challenging and risky. Sifaka (Propithecus verreauxi) have particularly slow life histories for their size, with long juvenile periods, protracted reproductive careers, and long life spans. Slow somatic growth poses potential mechanical challenges for juvenile sifaka who use thigh-powered vertical clinging and leaping to follow group members during travel. I examined mechanical and energetic costs of movement in developing sifaka. I instrumented 8 wild sifaka (3 yearlings, 3 subadults, 2 adults) in 4 social groups with inertial sensors measuring tri-axial acceleration for …

In order to participate in the Paralympic Games, the preparation process for professional athletes is planned at least four years in advance. Interruptions to this schedule can present significant challenges for elite athletes. Such was the case in 2020 with widespread cancellations of many athletic events due to the COVID-19 pandemic. The impact of in-home isolation can potentially cause athletes to experience different psychological conditions, including depression and anxiety as well as losing motivation. The purpose of this study was to …

The Impact Of Sleep Quality Combined With Physical Activity On Autonomic Function (24-Hour Hrv) In College Students, Meghan Peterson

Masters Theses, 2020-current

Long-term poor sleep quality is associated with health outcomes that can lead to autonomic nervous system dysfunction. Both cardiorespiratory fitness and physical activity (PA) are associated with improvements in autonomic function and heart rate variability (HRV). Markers of fitness and sleep were explored to determine the degree of contribution to autonomic dysfunction. A total of 15 subjects, (age = 20.6±0.5; BMI = 23.9±1.0) completed 7 days of physical activity and sleep assessment via accelerometry. Participants then completed a graded exercise test to determine cardiorespiratory fitness (VO_2max), followed by a 24-H HRV measurement. HRV through LF:HF ratio was negatively …

Understanding Context Dependent Responses To Climate Change In Arizona Tiger Salamanders (Ambystoma Mavortium Nebulosum), Kentrell Richardson

Masters Theses, 2020-current

Future emissions scenarios project climate change to increase average global temperatures by at least two ℃ in the next 50 years resulting in changes in local climate and causing increased variability within microclimates. Ectotherms are especially sensitive to climate change due to their dependence on environmental temperatures to regulate physiological functions. Changes in temperature are likely to impact thermally cued processes within amphibians and result in changes in variable magnitudes and directions within local populations.

Salamanders were placed in cups and partially submerged in a water bath and heated at a rate of ~0.27℃/ minute. Once salamanders were unable to …

Weight Change In College Freshmen: Personal, Interpersonal And Situational Influences, Kristin L. Kuhlmann

Dissertations

Obesity has become the most significant noninfectious health risk in the United States, and the major causes of death and disability are shifting to chronic, non-communicable health conditions that are largely attributable to physical inactivity, overweight and obesity, and other diet-related factors. Among children and adolescents, the overweight/obesity rate is approaching 32%, with 17.9% of adolescents becoming obese. While the obesity rate has doubled in all age groups in the United States, it has tripled among young adults aged 18 to 28 years, and 70% of adolescents who are at a healthy weight will become overweight or obese as adults. …

Land Dispossession And Native American Climate Adaptation: The Hopi Tribe, Jessica M. Curran

Student Theses 2015-Present

Since the 16th century, Native American communities have lost over 99% of their historical land. New settlers came in and completely destroyed the natives’ way of life, disregarding the love and respect that was once shown for mother earth. Flash forward to the 21st century and we are now struggling with the constant rising threat of climate change. However, this is not an equal fight. Past studies have shown that Native American communities are more vulnerable to climate change hazards compared to the general United States population due to their existing disparities. This paper focuses on the Hopi Tribe and …

The Value Of Zoos And Aquariums; A Perspective Via The Bronx Zoo And New York Aquarium, Reiariel D. Garcia

Student Theses 2015-Present

Zoos and aquariums have always been a controversial topic. The image of animals behind bars is synonymous with zoos and aquariums from all over the world and that's all most people see. Zoos and Aquariums go much deeper than that negative perception and the notion that we are “locking away” animals solely for our selfish entertainment clouds zoos and aquariums higher purposes. Chapter 1 focuses on the histories of zoological parks, it brings to light some of the environmental problems zoos and aquariums are striving to fix while revealing to us why zoos possess such stereotypes. Chapter 2 dives into …

Meet Them Where They Are: Investigating The Feasibility And Acceptability Of Artificial Intelligence-Avatar-Delivered Community-Based Psychological First Aid Programming In A University Setting, Sarah Ryann M. Fortner, Joshua Semko, Stefan E. Schulenberg

Honors Theses

The purpose of the current study was to evaluate the acceptability and feasibility of implementing an Artificial Intelligence (AI) avatar to deliver Community-Based Psychological First Aid training (CBPFA) to undergraduate students in a university setting. College students report high stress levels, and chronic stress is associated with negative physical, mental, and academic outcomes. CBPFA may be an effective way for colleges and universities to provide students with psychosocial support; however, traditional models utilize in-person training, which may not be accessible on a large scale. The present study developed a web-based AI-avatar-delivered CBPFA training to provide an alternative training modality. The …

Determining The Effect Of Cuff Deflation On Post-Exercise Arterial Occlusion Pressure, John Benton

Honors Theses

While it is recommended that blood flow restriction be applied relative to pre-exercise arterial occlusion pressure (AOP), no guidelines exist for an initial rest period prior to the measurement. Remeasuring AOP post-exercise can be used to estimate the cardiovascular response. When measuring post-exercise (pre-) AOP, different methods could be used. Some increase the cuff pressure from blood flow restriction exercise pressure (without deflation), or deflate the cuff prior to post-exercise (post-) AOP measurement. It is unknown if pre-AOP is affected by initial rest period, or if post- AOP is affected by cuff deflation. Thus, the purpose of this study was …

Influences Of Post-Fledging Protein Supplementation On Growth And Reactive Stress Response In Zebra Finches (Taeniopygia Castanotis), Gabrielle Morris, Mary Lindley Tharp

Honors Theses

Protein needs of non-poultry birds, like Zebra Finches (ZF) are understudied. ZFs consume proteinaceous half-ripe seeds during breeding and chicken eggs are recommended supplements for captive ZFs; but developmental needs are unclear. Eggs contain essential amino acids that impact the “stress” hormone, corticosterone (CORT). Diet and corticosterone influence avian growth and stress management. Juvenile egg-fed ZFs outgrow seed-fed birds. Juvenile egg-supplementation boosts adult male attractiveness due to cheek patch augmentation compared to seed-only birds. Across studies, timing of diet (nestling Vs. fledgling) varies, both sexes have not been included, and simultaneous measures of growth and corticosterone are lacking. We are …

A Case Study Of California's Maternal Health Landscape And Recommendations For Mississippi, Kinley Miller

Honors Theses

This paper is a case study of California’s maternal health landscape, reflecting its exceptional approach to the maternal health crisis. I review several policies: the creation of the Maternal Quality Care Collaborative, the Maternal Data Center, and the Maternal Mortality Review Committee, maternal health toolkits, Medicaid expansion, extended postpartum Medicaid coverage, paid family leave, C-Section Honor Roll, and maternal mental health measures. The case study suggests that all of these policies in conjunction with one another correlates with a decrease maternal mortality. California’s proactive approach and ability to mobilize public and private entities are key attributors to its success in …

The Relationship Between Family Communication Patterns, Conflict Strategies, And The Development/Management Of Eating Disorders, Ana Moyers

Honors College Theses

Eating disorders persist as one of the most prominent psychological and physiological illnesses among young adults and adolescents. Nonetheless, most research in the field focuses on external factors that influence the development of these disorders such (i.e., social media and an idolized body image). There is less research to investigate the role of an individual’s environment, more specifically the family dyad and communication related to such eating disorders. The family unit remains, often, the primary means of socialization for individuals during developing years, thus, this study seeks to expand on how current family communication and family climate contribute to eating …

Mothering As Feminism, Meera Patel

MFA in Illustration & Visual Culture

This critical essay proposes the concept of mothering-as-feminism, with the intention of interrogating American ideals of mothering and caregiving. Reforming the way we view mothering, as it relates to feminism, requires a re-evaluation of the American role of women and mothers—and how they are portrayed (and therefore seen and understood), valued, and supported. Focusing on the evolution of feminist theory throughout the past 70 years, as well as personal and secondary experiences, I demonstrate how political and social change occurs generationally and is dependent on the education of our children. Ultimately, I show the important role children’s literature plays …

Forget Us Not, Jamie Harris

MFA in Visual Art

I create because I mourn, to seek comfort in the knowing and sharing of Suppressed Histories, and to find joy in the rediscovering of lost stories. I create the vessel, which for me is akin to the human body. A form containing memories, wisdom, a soul, and a space for transportation between plains. I paint to capture moments in times of joy and sorrow. To make memoriam, I pay homage to past, present, and future.

Sensor-Controlled Digital Game For Heart Failure Self-Management: Protocol For A Randomized Controlled Trial, Kavita Radhakrishnan, Christine Julien, Matthew O'Hair, Rachel Tunis, Grace Lee, Angelica Rangel, James Custer, Tom Baranowski, Paul J Rathouz, Miyong T Kim

Faculty, Staff and Students Publications

BACKGROUND: Heart failure (HF) is the leading cause of hospitalization among older adults in the United States. There are substantial racial and geographic disparities in HF outcomes, with patients living in southern US states having a mortality rate 69% higher than the national average. Self-management behaviors, particularly daily weight monitoring and physical activity, are extremely important in improving HF outcomes; however, patients typically have particularly low adherence to these behaviors. With the rise of digital technologies to improve health outcomes and motivate health behaviors, sensor-controlled digital games (SCDGs) have become a promising approach. SCDGs, which leverage sensor-connected technologies, offer the …
