Effects Of Structure Of Mepegn Polymers On Hydroxide Conductivity In Anhydrous Anionic Exchange Membranes, Athan M. Gregory

Honors Theses

Anhydrous hydroxide ion (OH-) conducting polymer electrolytes composed of a 1-methyl-pyrrolidinium (1mp) head group linked to various MePEGn (n = 3, 7, 12) backbones were prepared. We have examined the structure of these anion exchange membranes to observe how the structure of the electrolyte affects the observed ionic conductivity. The structural parameters investigated were polymer length, viscosity, fractional free volume (FFV), and volume fraction of PEG (Vf,PEG), and each polymer varied in these properties. Through a comparison of the conductivity and structural parameters in the MePEGn-based anion electrolytes, we have shown that each of these structural properties weakly affects the …

Storytelling: A Natural Mnemonic, Hailey Stephens

Honors Theses

The present study explored the effectiveness of storytelling as a teaching method in enhancing memory performance for educational material compared to traditional lecture-based instruction. Memory plays a crucial role in learning, and effective teaching strategies should facilitate information encoding, retention, and retrieval. Storytelling, an ancient yet often overlooked pedagogical tool, has been shown to engage students emotionally and cognitively, making presented content more memorable. In the present study, participants were randomly assigned to either a storytelling-based instruction group or a traditional lecture group. Both groups received instruction on the ASSURE Model and were tested immediately after the lesson and again …

Phishy Pages - The Design Of A User-Interactive Website For Phishing Attack Evaluation, Evan C. Gregory

Honors Theses

Phishing attacks are a widespread, malicious phenomenon. These attacks steal people’s personal information, causing them ruin and lining the pockets of criminals. What makes them so dangerous is that they come in a variety of forms, including emails, websites, phone calls, and social media can be vectors for attackers. Fortunately, these attacks can be stopped by informing potential victims of common signs to look out for. Training is one of the best methods people use to teach web-users how to protect themselves. To train them, however, users must be taken through many examples of phishing attacks to learn the characteristics …

Cardiovascular Disparities In Mississippi: A Sociological Study Of Heart Health Literacy Among University Students, Laney Etheridge

Honors Theses

Mississippi ranks among the worst states in the United States for cardiovascular health, with high rates of heart disease, obesity, and hypertension. This thesis examines how race and gender influence heart health literacy and behavioral practices among University of Mississippi students. Utilizing a mixed-methods approach, this study combines quantitative survey data from a stratified random sample of 1,000 students with qualitative interviews from a public health professional specializing in cardiovascular health and a student heavily involved with on-campus heart health programs. The findings suggest that disparities in heart health literacy both align and differ with broader social stratification patterns observed …

The Power Of Parental Responses: Emotional Invalidation And Its Association With Adolescent And Emerging Adult Anxiety And Emotion Regulation Across Genders, Ashlynn Payne

Honors Theses

Adolescence and emerging adulthood are critical developmental periods marked by increased vulnerability to psychological distress, particularly anxiety and difficulties in emotion regulation. One factor that may contribute to this vulnerability is parental emotional invalidation. Although prior research has linked parental invalidation to adverse emotional outcomes, few studies have examined how these associations differ by caregiver and child gender. The current study evaluated how maternal and paternal emotional invalidation interacted with gender to influence anxiety symptoms and emotion regulation difficulties among 45 adolescents and emerging adults (n = 9 boys, 36 girls) between the ages of 13 and 22 years (M …

Overlooked: The Nuanced Struggles Of Autistic Women, Autumn L. Payne

Honors Theses

Overlooked is a documentary short film that seeks to shine a light on the nuanced struggles of autistic women in a neurotypical world. This short documentary consists of three interviews with autistic women from different backgrounds. Each diagnosed during a different stage of life, they reflect on their journeys to receiving an Autism Spectrum Disorder (ASD) diagnosis and its impact on their lives. These conversations reveal an overwhelming lack of resources for autistic people, especially for women, people of color, and members of the LGBTQIA+ community. With the diagnosis criteria for ASD being historically based on white males, women and …

Assisted Reproductive Technologies For Southern Cricket Frogs (Acris Gryllus), Audrey Grace Koltz

Honors Theses

Amphibians are facing the most drastic biodiversity declines of all vertebrates, with an estimated 41% of amphibians threatened with extinction. Captive breeding programs employ a variety of assisted reproductive technologies including environmental manipulation, hormonal therapies, artificial fertilization, and gamete preservation to augment vulnerable populations and optimize genetic diversity. Amphibians require a species-specific combination of environmental, social, and physiological cues to reproduce, which makes universal and successful captive breeding programs especially elusive. Here, I investigate assisted reproductive technologies for a small frog species, the southern cricket frog (Acris gryllus). Establishing successful methods for southern cricket frogs may yield promising results for …

Relationship Between Maternal Plasma Retinol And Provitamin A Carotenoids With Fetal And Infant Kidney Development, Anum Akbar

Theses & Dissertations

Vitamin A plays a critical role in fetal organ development. Studies suggest that maternal vitamin A deficiency affects fetal nephron numbers, potentially leading to smaller kidney sizes and an increased risk of chronic kidney disease later in life. However, human studies exploring maternal vitamin A's impact on fetal kidney development lack longitudinal data and within-cohort comparisons. Furthermore, the influence of provitamin A carotenoids (α-carotene, β-carotene, β-cryptoxanthin) on kidney size remains unexplored. This dissertation addresses these gaps by analyzing relationships between maternal and cord plasma retinol and provitamin A carotenoid concentrations with fetal and infant kidney sizes. Our prospective cohort …

Coxiella Burnetii Manipulation Of Membrane Contact Sites In The Intracellular Niche, Margaret F. Sladek

Theses & Dissertations

Coxiella burnetii is a highly infectious and environmentally persistent bacterium that causes the disease Q Fever. Its intracellular home, the Coxiella-Containing Vacuole (CVV), is formed from fusion of host-derived vesicles and is rich in sterols - yet cholesterol accumulation in the CCV is bacteriolytic. Our lab’s goal is to understand how Coxiella manages intracellular cholesterol levels and survives within the host. One way Coxiella may modulate CCV cholesterol is through membrane contact sites (MCS), areas where molecular complexes bridge two organelles and exchange lipids. This thesis explores how Coxiella uses both a mammalian lipid transfer protein and bacterially-encoded effector …

Cholestasis And Fluid Flow Are Biomechanic Regulators Of Cholangiocarcinoma Progression, Andrew Oleksijew

Theses & Dissertations

Cholestasis, altered or absent bile flow, is associated with poor survival in patients with cholangiocarcinoma, an aggressive cancer of the biliary epithelium. Changes in bile flow often result in stricture or obstruction. Experimental cholestasis promoted tumor growth and progression. However, studies are needed that directly assess the mechanical interaction between bile flow, or bile shear stress, and cholangiocarcinoma signaling. We hypothesized that cholestasis and absent bile shear stress activated cancer signaling and increased aggressive cellular behaviors such as proliferation and migration. Fluid shear stress approximating bile flow was applied by orbital culture plate method and compared to identical static culture …

Evaluating The Therapeutic Potential Of Geranylgeranyl Diphosphate Synthase Inhibitor, Ram2061, In Myeloma Bone Disease, Molly Muehlebach

Theses & Dissertations

Multiple myeloma (MM) is a hematological malignancy of the plasma cells which often results in lytic bone disease. Myeloma bone disease (MBD), characterized by diffuse osteopenia, bone lesions, or pathological fracture, results from MM mediated promotion of osteoclast resorption and dual inhibition of bone formation, drastically reducing bone strength and integrity. Development of MBD is known to significantly impact patient quality of life and increase risk of mortality. Considering that up to 80-95% of MM patients are expected to develop bone disease post-initial MM diagnosis, there is a significant need within this population for therapeutics which address both MM disease …

Intrinsic And Extrinsic Drivers Of Bioaerosol Decay: Investigating Pathogen Stability Of Bacteriophage Ms2, Sin Nombre Virus, And Sars-Cov-2 In Simulated Environments, Elizabeth A. Klug

Theses & Dissertations

The threat posed by a virus as a bioaerosol depends largely on its stability under various environmental conditions (relative humidity (RH), sunlight, ozone, etc.). This stability is typically studied through aerosol decay—how the virus' viability changes over time when exposed environmental conditions. The Goldberg rotating drum, a widely used tool for studying bioaerosols, has been the basis of such research (Goldberg et al., 1958). However, it has significant limitations, including an inability to measure initial pathogen infectivity loss and the use of small sample volumes. Additionally, it does not answer the question of what intrinsic factors (lipids, proteins, nucleic acids) …

Region-Specific Brain Targets Drive Circuit Formation And Maturation Of Human Retinal Ganglion Cells, Kang-Chieh Huang, Han-Yin Jeng, Qudrat Abdulwahab, Victoria R Cuevas, Eyad Shihabeddin, Claire Young, Melody Hernandez, Jason S Meyer, Nicholas M Tran, Melanie A Samuel

Faculty, Staff and Students Publications

Human vision relies on retinal ganglion cells (RGCs), and their connectivity with distinct brain regions enables higher order visual processing. RGCs vary considerably between species, and small model organisms display distinct RGC innervation patterns from that in humans. There is thus a need for robust models of human RGC circuit formation that preserves innervation specificity. Here, we developed an in vitro microfluidics eye-to-brain connectivity model using human pluripotent stem cell (hPSC)-derived RGCs to assess brain region-specific connectivity features. We find that cultured human RGCs segregate their dendrites and axons and display axonal features that align with that of their in …

Finding What Keywords Miss: Vector Search For Digital Forensics, Adil Koeken, Samay Nandwana, Avantika Shah, Vinicius Lima, Umit Karabiyik

Purdue Polytechnic Graduate Student Poster Symposium

Digital investigators face challenges searching through massive data when coded language evades keyword searches. Our research shows how vector embeddings enhance digital forensics by detecting implicit drug references in social media. Using LLM2Vec with instruction-based embeddings, we significantly outperformed traditional keyword searches when dealing with slang, enabling investigators to find content based on meaning rather than exact word matching.

The Rapsody Syllabus: Rescripting The Erasure Of Black Women And Black Women Educators Through Rapsody’S Album Eve, Eghosa Obaizamomwan-Hamilton

Black Educology Mixtape "Journal"

This syllabus explores the connections between Rapsody’s album and the experiences of Black women, with an emphasis on education. Much like Black women in education, Rapsody 's talents are often obscured and minimized. Her album “Eve ” is a love letter to Black women and serves as a mirror for Black women educators. This syllabus centers on Black women and highlights the beauty and magic of our presence within oppressive institutions. It works to amplify and extend the nonfungible existence of Black women, the humanization of our voices and words as sacred texts, and illuminate our ever-evolving contributions. Black women’s …

Ai Inventorship: Recognizing The True Inventors Requires Change, Nicholas Scambia

St. John's Law Review

(Excerpt)

The Analytical Engine was conceived almost two hundred years ago—a general-purpose programmable computing engine which had essential features resembling a modern-day computer. While truly a marvel for its time, the Analytical Engine lacked the ability to perform functions on its own, as it was only able to do tasks for which it was programmed.

Today, artificial intelligence (“AI”) has become increasingly popular and powerful and is projected to keep growing. AI demonstrated its autonomous strength to the whole world on national TV when IBM’s Watson competed on Jeopardy!, beating the game show’s legends Ken Jennings and Brad Rutter. Since …

Ben Crump And Racialized Professionalism, Katherine A. Macfarlane

St. John's Law Review

(Excerpt)

Benjamin “Ben” Crump is the country’s most influential civil rights lawyer. His advocacy led to the arrest and prosecution of George Zimmerman. He has represented the families of George Floyd and Breonna Taylor and many others, negotiating record-breaking settlements despite a body of civil rights precedent that is overwhelmingly pro-defendant. Crump is also a modern lawyer who uses press conferences and social media to advance his clients’ cause. To his clients, he is a lawyer, confidante, and friend. Yet, based on the way national media covers him, his significance isn’t always clear. When his work isn’t being erased, it’s …

International Perspectives On Research Data Management Services In Academic Libraries, Chris Reynolds, Kayla Richards

School of Information Student Research Journal

The information landscape in academic libraries is undergoing a massive fundamental shift, from scarcity to abundance aided by changes in technology. One such change is the development of research data management (RDM) and their related services. Research data management services (RDMS) allow libraries to aid in “creating, finding, organizing, storing, sharing and preserving data within any research process” (Cox & Verbaan, 2018). Our research seeks to understand where RDMS is currently at on the global stage. Are international institutions currently developing RDM services? What is needed for successful implementation? And are there any considerable challenges? Through a comprehensive literature review, …
