Dazed & Confused... And... Psychotic?, Judy Ann Clausen, Joanmarie I. Davoli, Benjamin W. Lacy Md

UF Law Faculty Publications

This Article examines marijuana’s impact on developing brains. Secondly, this Article explores the Green Rush – the rise of the multibillion-dollar marijuana industry and the media and legal environment that unleashed massive marijuana commercialization. The Article compares decriminalization with commercialization, illustrating that it is possible to address social justice concerns of arrests, incarceration, and criminal records for marijuana use without unleashing a multibillion-dollar industry that markets to youth. The Article concludes by exploring approaches from Australia, the United Kingdom, and Sweden, all of which continue to criminalize marijuana, in part because they have observed the U.S. Green Rush and its …

Cell Type-Specific Production Of Amyloid Precursor Protein During Infection Is Dependent On The Strain Of Herpes Simplex Virus 1, Mia Elias

Honors Theses

Cleavage of amyloid precursor protein (APP) generates the antimicrobial peptide amyloid beta (Aβ), the accumulation of which is linked to Alzheimer’s Disease (AD) pathogenesis. Whether processing of APP contributes to anti-viral responses is debated. Herpes Simplex Virus Type 1 (HSV-1), a neurotropic double-stranded deoxyribonucleic acid (DNA) virus, establishes lifelong latency and can cause a range of outcomes, from asymptomatic infection to herpetic encephalitis (HSE). Whether disparate outcomes are dependent on HSV-1 strain is unknown. Using three differentially virulent HSV-1 strains, we compared the regulation of APP-associated proteolytic processing in both a corneal infection murine model and an in vitro model. …

Development Of A Multi-Use Modular Microfluidic Platform Using 3d Printing, Carson Emeigh

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

Microfluidic lab-on-a-chip (LoC) technology has driven numerous innovations due to their ability to perform laboratory-scale experiments on a single chip using microchannels. Although LoC technology has been innovative, it still suffers from limitations related to its fabrication and design flexibility. Typical LoC fabrication, with photolithography, is time consuming, expensive, and inflexible. To overcome the limitations of LoC devices, modular microfluidic platforms have been developed where multiple microfluidic modules, each with a specific function or group of functions, can be combined on a single platform. Modular microfluidics have overcome some of the limitations of LoC devices, but currently, their fabrication is …

Novel Methods To Increase Carbon Mineralization Rates, Charles Ekpewani Kwaku Kporxah

Theses and Dissertations

Humans have contributed to climate change through anthropogenic emissions of greenhouse gases, such as carbon dioxide (CO2), methane, chlorofluorocarbons, and nitrous oxide, into the atmosphere. CO2 emissions contribute approximately 79% to the warming of the Earth's surface. Various tactics have been developed to slow down global warming and prepare for climate change, including carbon mineralization. Carbon mineralization is a process that converts CO2 into solid mineral forms, such as carbonates, emulating the natural weathering process of alkaline silicate rocks. However, the rate of natural weathering is slow, occurring on geologic time scales. Therefore, the goal of this research is to …

Constructing And Understanding Angler License Typologies And Response To Landscape Change, Michael James Lant

Theses and Dissertations

The future of conservation could hinge entirely on voluntary contributions of individualsand their relationship with landscape features. Conservation funding is becoming increasingly unstable, shifting from large non-governmental organizations to voluntary user-pay funded organizations. At the same time the natural world is experiencing dramatic changes, such as the global extinction crisis and widespread loss of biodiversity. User-pay-experience models, such as recreational fishing in North Dakota, are challenged by the uncertainty surrounding angler participation and license sales. Our objectives were to 1) investigate license purchasing dynamics among resident North Dakota recreational anglers to reveal potential angler license typologies, 2) compare trip-related behavior …

Crop, Soil and Environmental Sciences Undergraduate Honors Theses

Museum biological collections store species data that can be utilized in research on biodiversity, environmental change, invasive species, public health, and disease. The University of Arkansas Arthropod Museum, which began in 1905, houses over 750,000 specimens and has not yet been digitized. Making data publicly accessible via the internet makes the data available to the entire scientific community. The goal of this project was to create a digital resource to allow greater access to the University of Arkansas Arthropod Museum holdings. To do so, data from Bombus (bumble bee) and Xylocopa (carpenter bee) specimens were databased in Excel and displayed …

Atmospheric Deposition Trends Are Primarily Decreasing In Arkansas And Tennessee, Anna Mccarty

Crop, Soil and Environmental Sciences Undergraduate Honors Theses

Atmospheric deposition has likely changed with the influence of increasing global temperatures and subsequent changes in precipitation across the United States and globally. The objective of this project was to analyze atmospheric deposition across northern Arkansas and Tennessee. The three specific objectives were to: i) evaluate trends in atmospheric deposition of various element/compounds, ii) assess the relationship between atmospheric deposition and rainfall, and iii) evaluate if rainfall-adjusted atmospheric deposition is changing over time. Six sites were analyzed from 1980 to 2022, including AR16, AR27, TN00, TN04, TN11, and TN14, which span over northern Arkansas and across Tennessee. The Mann-Kendall Test …

Screening For Potential Swine-Origin Probiotics With Antimicrobial Activities, Christina Lim

Animal Science Undergraduate Honors Theses

The prevalence of antibiotic resistant bacteria is a leading issue worldwide. Recently, there was a new law banning the use of antibiotics within the swine industry. For decades swine producers have mixed subtherapeutic amounts of antibiotics in swine feed to prevent potential infections and to increase growth rate. However, due to the constant exposure of antibiotics to these ever-evolving pathogens, the population of antibiotic resistant bacteria has increased exponentially. Currently, the swine industry is scrambling to find a suitable alternative to antibiotics that possesses antimicrobial activity and potentially promotes growth. The objective of this study was to investigate the ability …

Effects Of Maternal Infant-Directed Sensory Cues On Early Weaned Piglet Behavior, Mattie Still

Animal Science Undergraduate Honors Theses

In the commercial pig production industry, weaning is a stressful time. Stress is related to loss in production due to increased incidence of illness, increased aggression, and reduced rate of gain, which results in economic losses for the producer. The purpose of this continuous behavior study was to explore the effects of provisional own-mother olfactory and auditory stimuli on early weaned piglet behavior and growth. During days 7-14 postpartum, the grunting of 12 individual sows was recorded while their piglets nursed. The audio files were put into a single loop with grunting occurring for 20 minutes followed by 60 minutes …

Exploring The Neuroprotective Effects Of Cannabinoids On Oxygen Glucose Deprived Neurons In An In-Vitro Model Of Stroke, Bhavya Chatragadda, Emily Potts, Hang Ma, Navindra Seeram, Claudia Fallini

Senior Honors Projects

Stroke is a leading cause of long-term disability and decreased mobility worldwide. During stroke, neuronal damage results from both the initial oxygen-glucose deprivation and the increase in excitotoxicity and oxidative stress after restoration of blood flow, a phase called Ischemia-Reperfusion Injury (IRI). Reducing the impact of these processes could result in better outcomes for post-stroke patients by preventing excessive neuronal death. Many natural compounds derived from the Cannabis Sativa plant have been tested for neuroprotective effects due to their potential antioxidant properties. We hypothesized that neurons treated with cannabinoids immediately after experiencing an acute ischemic event will have an overall …

The Impact Of Covid-19 Mammography Rates In Rhode Island, Grace Lavallee

Senior Honors Projects

In the United States, 1 in 8 women will be diagnosed with breast cancer in their lifetime. When detected early, breast cancer is among the most treatable cancers. Mammograms are considered one of the most important tools for early detection, however there are disparities in mammography screening. Those in marginalized communities, including people of color, low-income individuals, and others face heightened barriers to accessing timely screenings and diagnosis.

Prior to Covid-19 pandemic, Rhode Island ranked highest in national surveys of mammography rates, and had made significant strides in reducing screening disparities. This study asks: What impact did the Covid-19 pandemic …

Reconnecting With Nature One Classroom At A Time, Bianca Apuzzo

Senior Honors Projects

Environmental science is more important to today’s society than it has ever been, and developing basic ecoliteracy is the easiest way we can work towards a more sustainable future. Ecoliteracy allows us to connect deeper to nature and provides us with the information needed to protect and restore our beautiful planet. We are rolling downhill, picking up speed as we go, through a silent mass extinction. The scariest part of it all: nobody seems to care.

In response to the lack of environmental education provided to today’s students, I have created a syllabus for a high school level science course …

Heuristic Expectations Of The Cinderella Effect As A Function Of Sexual Dimorphism In Men's Facial Structures, Lindsey Eagan

Psychological Science Undergraduate Honors Theses

Masculinized male faces have an ambivalent signal value, wherein perceivers recognize various coalitional benefits and costs. Within parenting domains, masculine men could afford protection toward their offspring despite potentially using more aggressive behaviors toward them. Nonetheless, the benefits of masculine fathers could be limited to their biological children while the costs toward stepchildren would be greater. Perceivers could develop implicit theories about parental behaviors as a visual corollary of the Cinderella Effect, or stepchildren’s greater vulnerability to abuse. Participants evaluated a series of masculinized and feminized male faces described as either biological parents or stepparents in domains related to positive …

Functional Stereotyping Of Women’S Self-Objectification As A Function Of Life History And Body Fat, Vienne Howay

Psychological Science Undergraduate Honors Theses

Individuals prioritize different goals as a function of stability in their environment, oftentimes leading people to prioritize reproduction in hostile ecologies. From this shift in priorities, perceivers could develop heuristics about how women may attempt to attract mates. Previous research suggests that higher levels of body fat are more attractive to men with a fast life history. With this awareness of men’s preferences in body fat, high-fat women from hostile ecologies could be expected to engage in more self-objectifying behavior in the service of mate attraction or attempting present themselves as objects of affection to men. This study tasked participants …

Invasive Shrubs Differentially Alter Autumnal Activity For Three Common Small-Mammal Species, Brian M. Connolly, Chad Zirbel, Carson Keller, Mark Fuka, John L. Orrock

Biology Faculty Scholarship

Seasonal variation in animal activity influences fitness and the intensity of ecological interactions (e.g., competition, predation), yet aspects of global change in the Anthropocene may catalyze shifts in seasonal activity. Invasive plants are components of global change and can modify animal daily activity, but their influence on animal seasonal activity is less understood. We examined how invasive woody shrubs (Autumn olive [Elaeagnus umbellata] and Amur honeysuckle [Lonicera maackii]) affect seasonal activity of three common small-mammal species by coupling experimental shrub removal with autumnal camera trapping for two consecutive years at six paired forest sites (total 12 …

A Copper-Selective Sensor And Its Inhibition Of Copper-Amyloid Beta Aggregation, Ngoc Kim Nguyen, Bella Poduska, Mia Franks, Manoranjan Bera, Ian Maccormack, Guoxing Lin, Alexander P. Petroff, Samir Das, Arundhati Nag

Chemistry

Copper is an essential trace metal for biological processes in humans and animals. A low level of copper detection at physiological pH using fluorescent probes is very important for in vitro applications, such as the detection of copper in water or urine, and in vivo applications, such as tracking the dynamic copper concentrations inside cells. Copper homeostasis is disrupted in neurological diseases like Alzheimer’s disease, and copper forms aggregates with amyloid beta (Ab42) peptide, resulting in senile plaques in Alzheimer’s brains. Therefore, a selective copper detector probe that can detect amyloid beta peptide-copper aggregates and decrease the aggregate size has …

Intolerable Masculinity: Screening Men's Shame And Embracing Curious Futures, Cole Clark

Film and Media Studies (MA) Theses

This thesis argues that to critique hegemonic masculinity and patriarchy in good faith, film and television must focus on the futures created through men’s ethical action in the present, rather than inert displays of men’s horrific behaviors that rely on audience shame as a tool for reclaiming men’s pride. Men’s freedom to change their situation is introduced through Manon Garcia’s (2022) notion of masculinity as an “impasse,” preventing men from authentic connection with others. This concept is furthered using David Buchbinder (2013), with the television examples Mad Men (Weiner 2007-2015) and Black Mirror (Brooker 2011-2023) each presenting a different masculine …

Real To Reel: The "Third Gender" Narratives And Queer Identity In Rituparno Ghosh's Bengali Films, Manjima Tarafdar

Film and Media Studies (MA) Theses

This thesis critically explores the third gender space that Rituparno Ghosh created in his later films, where he either featured and/or directed the films. The Bengali filmmaker, Rituparno Ghosh was one of the very few filmmakers in India who consciously and vocally spoke for the sexual minorities and represented them in his films. Focusing on the films, Arekti Premer Golpo, Memories in March and Chitrangada: The Crowning Wish, the thesis looks at the films that negotiated through the in-betweenness of gender identity, not solely lying within the binary of gender. Through this representation of the third gender space, …

Bluey And Adult Fandom: The Importance Of Play In Culture, Olivia C. Gerzabek

Film and Media Studies (MA) Theses

This thesis explores the animated children’s show Bluey(2018 -), its ever-growing appeal to millennials, and the online fandom that these millennials have formed. The thesis outlines a brief history of media aimed at children and families, starting with the children’s matinees of the 1930s to children’s educational media of the 1960s through the 2000s with shows like Spongebob Squarepants (1999 -) and Shrek (2001) appealing to a broad audience of all ages. Compounding on the history of animation and family-centered media, the advent of social media allows users to revisit media they have nostalgia for, share with others, and create …

Mindfulness And Prosocial Behavior: A Study Of The Light Triad Of Personality Traits, Jake Goedert

University Honors Program Senior Projects

This study examined the relationship between mindfulness and a constellation of prosocial features known as the Light Triad. The past twenty years of psychological research has seen many studies confirming the benefits of mindfulness regarding the psychological health of individuals, but little research has been done to suggest the potential social benefits imparted by mindful qualities of awareness. In this study, 80 Northeastern Illinois psychology students were recruited through NEIU’s SONA platform and were presented with five separate questionnaires designed to assess prosociality (humanism, faith in humanity, and Kantianism), mindfulness, self-compassion, self-care competency, and felt purpose in life. This study’s …

Implementing Practice With Children Affected By Trauma In The Field Of Speech-Language Pathology, Avery Liley

Undergraduate Honors Theses

There is currently a lack of research in the field of Speech-Language Pathology regarding the understanding and implementation of appropriate practice when working with children who have experienced a variety of forms of trauma, including maltreatment. Previous research has shown a significant correlation between trauma exposure and speech and language deficiencies, so children who fall in this group are often involved in speech-language pathology services. Therefore, it is essential that clinicians in this field obtain a better understanding of how to implement appropriate trauma-informed care. This research poses the question, “What is the relationship between childhood maltreatment and the development …

Gene Expression Of Cellular Respiration Enzymes In Breast Cancer, Madison Turner

Undergraduate Honors Theses

In the United States, approximately 2.0 million people will be diagnosed with cancer in 2024 (Siegel et al., 2024). 15% of those diagnoses will be breast cancer with 2% resulting in death (Siegel et al., 2024). Using normal breast tissue, metastatic breast cancer, and relapsed breast cancer to compare the gene expression of enzymes involved in glycolysis and the citric acid cycle could help with diagnosis and targeted treatment of altered metabolism. Cellular respiration is a set of metabolic processes; glycolysis, citric acid cycle, and oxidative phosphorylation. Normal cells use cellular respiration to convert nutrients into ATP (Chandel, 2021). Cancer …

Determinism & Free Will: An Exploration On Gender Identity As Evidence For Compatibilism, Daniel Mangandi-Escobar

Undergraduate Honors Theses

Determinism is a philosophical concept asserting that every event and action in the universe has been determined by previous causes, which has caused considerable debate within philosophy. Two critical issues within this discussion are the implications of determinism for human agency and moral responsibility. In this work, I argue that free ill is possible, rejecting hard determinism. Specifically, I will be arguing in favor of compatibilism, which is the view that free will can exist even within a deterministic world. From this perspective, free will is not opposed to determinism. Instead, our choices and actions can still be considered free …

Little Lil's Big Adventure: How I Wrote A Children's Book On Adoption, Lilia Moritz

Undergraduate Honors Theses

Being adopted is a unique and complex experience; one of which can be expressed and learned about through children’s literature. The research behind writing a book on adoption includes adoption statistics, actions taken by adoptive parents, cognitive development of adoptees, windows and mirrors in books, adoption documentation from adoptive parents, authors and their relation to adoption, and how biological and adoptive parents are portrayed within the books. My methods included observing and looking at other children’s literature, creating my storyline, using pictures from my own story, and the publishing will be done after this project. Limitations involved include having a …

Rebels And Dubliners: Motherhood In Three 20th-Century Irish Texts, Sara S. Barenfeld

Theses, Dissertations and Culminating Projects

This thesis explores representations of motherhood across several genres in Irish literature. In my essay, I look at two short stories from James Joyce’s Dubliners (1914): “The Boarding House” and “A Mother.” I argue the way spatiality functions in “The Boarding House” and “A Mother” reveals Mrs. Mooney’s and Mrs. Kearney’s overall ability to exercise maternal agency; it shows the extent to which their agency is circumscribed. The spaces themselves act as defining factors contributing to the mothers’ abilities to engage with power structures and ultimately fail or succeed in their endeavors. I also examine two autobiographies: The Autobiography of …

Bathsheba And Sue: Hardy's Independent Heroines, Alexandra Acosta

Theses, Dissertations and Culminating Projects

In Thomas Hardy's literary landscape, the female protagonists Bathsheba Everdene and Sue Bridehead emerge as complex figures who challenge and navigate the rigid social norms of Victorian society. Through their journeys in Far from the Madding Crowd and Jude the Obscure, respectively, Hardy explores the themes of independence, conformity, and the impact of societal pressures on individual agency.

Bathsheba Everdene, in Far from the Madding Crowd, initially stands as a symbol of independence, defying the conventional gender roles expected of Victorian women. However, her trajectory reveals the nuanced ways in which societal expectations shape her choices, ultimately leading her to …

The Combined Effects Of Nacl And Beet Juice On Germination And Early Seedling Growth Among Raphanus Sativus L., Justin Howell

Theses, Dissertations and Culminating Projects

Salt pollution and soil salinization via secondary pathways is a global problem. One practice which contributes to increased salinity in soils and other natural systems is the application of road deicers in colder regions. Increased salinity in soils negatively affects plant growth and microbial activity. In an effort to decrease the amount of salt applied to roads, salts are applied as brine. Liquid organic additives are incorporated into these brines to foster better adherence of the salt to impermeable surfaces. One common additive is beet juice, a byproduct of sugar extraction. Beet juice contains high levels of phosphorus and organic …

Investigating The Evolved Tolerance Of Zooplankton To Salt Pollution: A Microcosm Study, Megan Klutts

Theses, Dissertations and Culminating Projects

Salt pollution caused by excessive deicer application on impervious surfaces is polluting freshwater ecosystems and negatively affecting freshwater organisms in temperate regions. Freshwater environments near oceans experience natural salt intrusion due to tidal cycles and storm events. Therefore, populations of freshwater organisms near marine environments might have evolved a tolerance to increasing salinities over millennia. This contrasts with freshwater organisms far from coasts that have experienced high baseline salt concentrations for the last few decades. The evolutionary effects of increasing salinities on freshwater organisms near and far from marine environments are not fully understood. Understanding differences in evolutionary responses to …

Decisions, Decisions: The Influence Of Anxiety On Decision Making, Allisun Romain

Theses, Dissertations and Culminating Projects

The purpose of the present study was to better understand the influence of state anxiety on decision making, including how constructs such as trait anxiety and emotional intelligence may moderate this relationship. Participants were randomly assigned to a state anxiety-inducing condition or a control condition. They were then prompted to complete a computerized dynamic decision-making task in which optimal performance requires exploring a novel decision environment and learning reward contingencies of the task. Prior to the experimental manipulation, participants also completed self-report measures of trait anxiety and emotional intelligence. Independent sample t tests were employed to measure differences between the …

Transcranial Magnetic Stimulation And The Rtpj (Right Teaching Parietal Junction), Molly Skowron

Theses, Dissertations and Culminating Projects

Theory of Mind (ToM) is conceptualized as the ability to infer the thoughts and feelings of others. Many studies have found that ToM abilities play a central role in collaborative communication between adults, and that teachers are more effective when they have high levels of ToM. One of the main brain regions implicated in ToM is the right temporoparietal junction (rTPJ), which is thought to be responsible for evaluating a person’s belief formation process. The current study had participants engage in a Lego model building task consisting of a director who instructed a builder on how to create duplicate models …
