Coping With Creativity - The Relationship Between Depression/Anxiety And Creative Coping In College-Aged Students, Nelly M. Dragu

Honors Undergraduate Theses

The relationship between creativity and mental illness has been established in the literature. There are multiple possible explanations for how mental illness and creativity are connected, and creativity has shown to be an effective treatment for different mental illnesses (for example, through art therapy). Despite this, there is limited research on which creative activities those with mental illnesses naturally use to cope. Information on the type of creative coping that the mentally ill naturally gravitate to and find most effective can further inform possible treatment plans and suggestions. This study aims to address gaps in the literature concerning how college-aged …

The Role Of Parental Attachment In The Relationship Between Adverse Childhood Experiences And Depression In Emerging Adult Males, Kerstin Gracia

Honors Undergraduate Theses

Experiencing adversity during childhood can impact mental health throughout adolescence and into adulthood. Adverse childhood experiences (ACEs) are comprised of different types of abuse, neglect, and household dysfunction. Children who experience ACEs are more likely to display internalizing (e.g., depression) and externalizing (e.g., acting out) behavior problems in adolescence. Those with insecure attachment styles are more likely to have grown up in a disorganized, inconsistent environment and have an increased chance of experiencing ACEs. The current study examined the relationships among ACEs, depression, and parental attachment in emerging adult men, with parental attachment tested as the mediating factor. It was …

Detection Of Micrornas In Blood Samples Using Biosensors For The Detection Of Early-Stage Lung Cancer, Nicholas Bruno

Honors Undergraduate Theses

Lung cancer kills more people in the U.S. a year than any other cancer. This is largely because patients often remain asymptomatic until stage 3, by which time the tumor is usually highly malignant. High radiation-producing screenings are the current method of lung tumor detection. These typically involve machinery for tumor visualization, such as computed tomography (CT) scans, positron emission tomography (PET scan), magnetic resonance imaging (MRI), and X-rays. Not only does radiation exposure from this equipment pose a risk to the patient, but any tumors detected by these scanning techniques are likely to be locally advanced. This suggests that …

Effect Of External Electromagnetic Stimulation On Microtubule Polymerization, Florian Alushi

Honors Undergraduate Theses

Intracellular processes are influenced by mass transport at different spatial and temporal scales, facilitated by diffusion and stochastic encounters between cellular components. While traditionally explained by short-range "lock and key" interactions, some processes involve rapidly fluctuating charges generating electromagnetic (EM) fields, allowing long-range biomolecular interactions. This challenges the conventional view that efficient biochemical reactions depend solely on random encounters and short-range interactions, suggesting EM fields play a crucial role in cellular dynamics. Microtubules (MTs) are essential components of the cell cytoskeleton, responsible for intracellular transport, cell migration, cell division, etc. Beyond their mechanical role, MTs have unique electromagnetic properties due …

Defining The Roles Of Blari Orthologs In Mycobacterium Abscessus, Lauren E. Bonefont

Graduate Thesis and Dissertation post-2024

The increasing incidence of Mycobacterium abscessus (Mab) infections is a global concern as the treatment failure rate is more than 50%. Mab is an opportunistic pathogen, thriving in harsh conditions in the environment and in hosts. To respond to these conditions, Mab employs many signal transduction mechanisms. This work characterizes two non-redundant systems using a novel mechanism in Mab: BlaRI-type protease-mediated two-component systems. In the Staphylococcus aureus prototype, BlaR binds β-lactams with a C-terminal extracellular sensing domain, activating BlaR through acylation and autoproteolysis. Activated BlaR then cleaves DNA-bound dimerized BlaI, disrupting repression by BlaI and enabling transcription …

The Reproducing Kernel Hilbert Space (RKHS) method is employed to estimate mathematically guaranteed Koopman eigenvalues and functions of the system, providing valuable insights into the periodic and chaotic behaviors of the system. Secondly, to further characterize …

Computational Approaches To Study Post Transcriptional Regulation Events, Naima Ahmed Fahmi

Graduate Thesis and Dissertation post-2024

A simplistic understanding of the central dogma falls short in correlating the number of genes in the genome to the number of proteins in the proteome. Post-transcriptional regulation, including alternative splicing and alternative polyadenylation contribute to the complexity of the proteome and is critical in understanding gene expression. In this dissertation, we aim to provide genome-wide detection and visualization of the transcript variants and quantify their significance in gene regulation. First, we propose a robust computational program to identify alternative splicing events from RNA-seq data, called AS-Quant. Our extensive experiments on simulated and real datasets demonstrate that AS-Quant can accurately …

Evaluating Sexual Dimorphism In Occipital Morphological Shape Through Modern Human Ontogenetic Changes, Jennifer S. Barritt

Graduate Thesis and Dissertation post-2024

Sex estimation is vital to building the biological profile in forensic anthropology. Cranial nonmetric traits are often used in adult sex estimation due to their sexually dimorphic nature. However, only one nonmetric trait is assessed on the occipital despite the bone’s postmortem durability. While these sex estimation methods were developed for use on adult crania, juvenile sex estimation is less accurate due to differences in the age at which individuals reach sexual maturity. The aim of this study was to improve upon existing sex estimation methods by accounting for shape differences that exist within the occipital. This study used computed …
