Masculinity, Pornography, And Inceldom: The Use Of American Ideals Of Masculinity And The Consumption Of Heterosexual Pornography To Radicalize Young Men Into Inceldom, Adelaide Verdugo-Thomson

AUCTUS: The Journal of Undergraduate Research and Creative Scholarship

The increased presence of the internet has granted many young American men a safe space to share beliefs and experiences, access new materials, and reach wider audiences. At the same time, heterosexual pornographic content has become increasingly accessible, and misogynistic beliefs are protected on various user-run forums. Male dominance in heterosexual pornography, the prevalence of rape myth acceptance, Incel slang, and the strong brotherhood bonds present in Incel communities may be radicalizing factors to encourage young American men to adopt Incel ideology. This literature review seeks to highlight the relationship between American masculinity, consumption of heterosexual pornography, and Inceldom in …

Investigation Of The Dyrk1a Regulation By Lzts2-Sipa1l1 Complex, Rebecca Gunnin, Austin Witt B.S., Larisa Litovchick M.D.,Ph.D.

UROP Posters

A region on chromosome 21, the Down Syndrome critical region (DSCR), is associated with major defects found in Down Syndrome, such as craniofacial malformations. DYRK1A is a gene found on chromosome 21 within the DSCR that encodes an enzyme, dual specificity tyrosine-phosphorylation-regulated kinase 1A. DYRK1A is known to phosphorylate many substrate proteins and is thought to be involved in tumor suppression, neurological development, cell cycle regulation, and aging. Recently, the Litovchick lab and others reported that DYRK1A also plays a role in the double-strand break repair of DNA, which could lead to mutations and tumorigenesis, if deregulated.

The Litovchick lab …

Exploring How College Professors' Mental Health Affects Their Perceived Attitudes Towards Adaptive Assessments., Jeen Joy Jj Joy Ms

Graduate Research Posters

This qualitative study aims to understand how a university professor's mental health influences their perceived attitudes toward adopting adaptive assessment practices. It studies the various intrinsic and extrinsic factors that may affect their mental health and, thereby, their perceived attitudes toward adaptive assessments. Intrinsic factors are individualist characteristics like physical health, perceived job satisfaction, and experience levels. Extrinsic factors are related to their work environments, like university resources, university support, political environment, or any external factors that can influence a professor's mental health. Existing literature suggests that intrinsic and extrinsic factors can affect a person's mental health, but the extent …

Evaluating The Influence Of Concurrently Available Non-Drug Reinforcers On Drug Reinforcement Using Sophisticated Preclinical Models Of Substance Use Disorder, Madison M. Marcus

Theses and Dissertations

The maladaptive allocation of behavior towards cocaine and away from other concurrently available non-drug reinforcers (e.g., family, health, work, etc.) is a key characteristic of cocaine use disorder (CUD) that is embedded into multiple diagnostic criteria for CUD. Accordingly, basic research conducted in a drug-vs-food “choice” context has improved our fundamental knowledge of the behavioral and neurobiological mechanisms of drug reinforcement. However, to date, these preclinical studies have only been conducted with food as the alternative reinforcer. The extent to which other non-drug reinforcers compete with cocaine-taking behavior is unknown. The studies in this dissertation establish two sophisticated discrete-trial cocaine-vs-alternative …

Minimal Sets, Union-Closed Families, And Frankl's Conjecture, Christopher S. Flippen

Theses and Dissertations

The most common statement of Frankl's conjecture is that for every finite family of sets closed under the union operation, there is some element which belongs to at least half of the sets in the family. Despite its apparent simplicity, Frankl's conjecture has remained open and highly researched since its first mention in 1979. In this paper, we begin by examining the history and previous attempts at solving the conjecture. Using these previous ideas, we introduce the concepts of minimal sets and minimally-generated families, some ideas related to viewing union-closed families as posets, and some constructions of families involving poset-defined …

Laying Out A Space: Spectral Geographies, Fictions Of The Soul, Erin D. Yerby

Theses and Dissertations

Laying out a Space: Spectral Geographies, Fictions of the Soul, arises out of my artistic practice, and thoughts behind my current project and MFA exhibition, Spectral Geographies.

Linking the problem of the world ‘out there’ or external space, to inner experience through painting as both medium and practice, my work expresses what I call inner geographies, spaces where intimate immensities, folding inside and outside, find expression. I think of my paintings as beginning with this gesture of laying out a between-space where the intimacies of waking dreams and visions are opened by, and grow into, actual places, …

Investigation Of Factors Affecting Reverse-Phase High Performance Liquid Chromatography, Rida A. Syed

AUCTUS: The Journal of Undergraduate Research and Creative Scholarship

This study focused on the application of reverse-phase high-performance liquid chromatography (RP-HPLC). RP-HPLC is used for the purification of organic molecules, including pharmaceuticals, natural products, and proteins. We developed a modified version of a United States Pharmacopeia (USP) procedure to separate and purify the chemical components found in Excedrin tablets. The goal was to investigate the relationship between retention time (Tr) and the capacity factor (k') of solutes. By varying the composition of the mobile phase and stationary phase, we experimentally determined the capacity factor of acetaminophen (APAP), caffeine, and aspirin. Our results show that the capacity factor (k') of …

Evaluation Of Cytokeratin-Specific Antibody And Autofluorescent Signals As Predictors Of Time Since Deposition For Saliva Samples, Dillon Ryder

Master of Science in Forensic Science Directed Research Projects

In a forensic investigation, STR profiles generated from biological evidence can frequently be informative to identify an individual or provide an investigative lead. However, STR typing does not provide information to answer activity-level questions which can be highly important to a criminal case, such as the Time Since Deposition (TSD) of biological evidence. Determining the relative time in which a biological sample was left at a crime scene would provide additional information regarding the timeline of a crime and a person of interest’s relationship to the scene. One proposed method of estimating TSD is to use flow cytometry to analyze …

Evaluating A Temperature-Dependent Mosquito Population Model, Morgan H. Jackson, Elizabet L. Estallo, Cheng Ly, Michael A. Robert

Graduate Research Posters

Dengue Virus causes over 390 million infections and around 40,000 deaths each year. This virus is primarily transmitted by the mosquito Aedes aegypti. The life cycle of these mosquitos is significantly impacted by temperature, however, temperature is often neglected in mechanistic models. Predictive models of mosquito populations thus require the inclusion of temperature and are valuable for helping medical officials plan for the impact of outbreaks. Using mosquito and climate data collected in Córdoba, Argentina from 2010-2013, we developed a non-autonomous ordinary differential equations model that includes temperature dependent parameters associated with mosquito life history. We performed local sensitivity …

Novel Feature Evaluation In Ultra-High Dimensional Right-Censored Data, With Applications To Head And Neck Cancer, Atika Farzana Urmi

Graduate Research Posters

Background: Head and neck cancer is the 6th most common cancer worldwide with an expected 1.08 million new cases each year. Such cancer data are ultra-high dimensional with thousands of clinical features and gene expressions, making it challenging for the traditional analytical tools to extract the potential biomarker for the cancer survival and control false discoveries. In addition, presence of heavy censoring can affect the screening procedures based on Kaplan-Meier (K-M) survival estimates.

Aim: To propose a model free, ultra-high dimensional feature screening method with two-dimensional survival outcome allowing false discovery rate (FDR) control.

Method: 516 primary tumor patients with …

Modeling Of Expansion Of Laser-Produced Aluminum Plasma Plume In Ambient Air, Edmund Tsiri Semaha

Graduate Research Posters

When a laser pulse is focused on an aluminum target, it interacts with the material’s surface and a plasma plume is developed. Hydrodynamic expansion of generated plasma plume consisting of interacting target and ambient gaseous species remain one of very significant subjects of plasma plume chemistry, yet to be fully understood. The revealing of fundamental physics processes which occur within these plasma plumes is not only of purely scientific advancement, but it is also of industrial interest. Our research focuses on the development of Computational Fluid Dynamics (CFD) model that is used to investigate the chemistry of expanding plasma generated …

Belaytionships Before Bros: Qualitative Analysis Of Gender Identity And Climbing, Samuel G. Crawford

Graduate Research Posters

Background. Sociological study of queer representation in sports has historically focused on gender within team sports, but less is known about these dynamics in more individual-oriented sports like climbing. Sociological scholarship on these dynamics in climbing has been relatively sparse. More mainstream analyses of queer issues in sports generally could potentially help examine these concepts. However, my experiences as a climber and former industry professional led me to believe that a more targeted qualitative sociological approach would provide valuable insight and perspective, particularly regarding this sports comparison.

Methods. This analysis draws upon ethnographic observation of a climbing gym in the …

Risk And Resilience: An Exploration Of Adverse Childhood Experiences, Protective Factors, And Internalizing Symptoms In Black Youth, Irene A. Jacobs

Theses and Dissertations

The study examines mechanisms of risk and resilience that influence the psychological well-being of Black youth. Previous literature has established a link between adverse childhood experiences (ACEs) and mental health outcomes in youth (Kerker et al., 2015; Thakur et al., 2020). A substantial amount of the ACEs literature solely focuses on risk factors (e.g., mental impairment, low SES, health risk behaviors) for poor outcomes associated with ACEs. Despite Black youth experiencing high rates of ACEs (Liu et al., 2019), the ACEs literature examining mechanisms of their resilience is sparse (Meeker et al., 2021). Given the state of the ACEs literature, …

Optimization Of Microfluidic Device Methodology For Optical Trapping Epithelial Cells In A Mixture, Brittney N. Hackworth

Master of Science in Forensic Science Directed Research Projects

Evidence containing biological mixtures can make DNA interpretation more difficult due to ambiguous allele calls and artifacts that may be present within electropherograms. Separating out these cell mixtures can be advantageous to the analysts’ analysis methods for identifying STR profiles with higher accuracy. A potential cell separation method that could be implemented in the beginning of the forensic DNA workflow is optical trapping.

This research utilized a 5W ytterbium linearly polarized laser split into two optical traps, paired with a microfluidic device to isolate spermatozoa and vaginal epithelial cells from a 1:1 mixture of vaginal fluid and 1:20 diluted seminal …

Comparison Of Cell Counts To Dna Yield In Mock Biological Evidence Samples, Jacob Sewell

Master of Science in Forensic Science Directed Research Projects

The implementation of rapid DNA analysis systems is of interest to forensic DNA casework, as this technology exhibits a sample-to-profile time of approximately two hours with limited handling of samples. This decreases the likelihood of contamination, and can potentially reduce DNA backlogs; however, current rapid DNA analysis systems do not execute one crucial step of the forensic DNA analysis workflow: human DNA quantitation. This step is necessary for DNA profiles to be compliant with the FBI’s Quality Assurance Standard 9.4, allowing DNA profiles to be uploaded and searched within the CODIS database. Coupling traditional qPCR methods with rapid DNA analysis …

Evaluation Of Direct-To-Amplification Cell Lysis Techniques For Forensically Relevant Non-Sperm Cells, Rhea Arya

Master of Science in Forensic Science Directed Research Projects

While efforts have been made to reduce the pervasive backlog of sexual assault evidence collection kits, the actual laboratory process remains very time-consuming due to the requirement of a differential lysis step before DNA purification, as well as intricate mixture analysis towards the end of the DNA workflow. Previous work in the Dawson Green laboratory at VCU has developed alternative solutions for differential extractions with sexual assault samples using both an in-tube and microdevice assay. Prior work led to the identification of an alternative sperm lysis method – alkaline lysis using 1M NaOH. However, the current lysis method used for …
