Early Adolescent Latinas And Non-Coital Sexual Behavior: Individual, Social, And Parental Variables, Ellita Williams Jan 2018

Early Adolescent Latinas And Non-Coital Sexual Behavior: Individual, Social, And Parental Variables, Ellita Williams

The Pegasus Review: UCF Undergraduate Research Journal

Unplanned pregnancies and sexually transmitted infections (STI) are increasing at a faster rate among young, low income Latinas as compared to other low income groups of girls. However, little is known about the non-coital behavior that early adolescent girls may engage in, which puts them at risk for initiation of intercourse. This study examines the frequency of a particular non-coital behavior, being touched below the waist on top of clothes, and investigates how girls who engage in this behavior differ from those who do not with respect to individual (biologic and cognitive), social (peer norms and acculturation), and parental (single …

"The Guy With The Problem": Reform Narrative In Disney's Beauty And The Beast, Faith Dickens Jan 2018

"The Guy With The Problem": Reform Narrative In Disney's Beauty And The Beast, Faith Dickens

The Pegasus Review: UCF Undergraduate Research Journal

When Disney's film Beauty and the Beast was first released in 1991, it was hailed by critics as a departure from the problematic portrayals of women that had plagued the company's previous efforts at converting fairy tales into animated features. Since then, feminist criticism has provided several different interpretations of the film, some of which seek to assign Beauty and the Beast to a specific literary genre. In looking at Disney's film as a literary text, critics such as June Cummins have argued that it most closely resembles a patriarchal classic romance, while others, such as Susan Swan, view it …

Analysis Of The Repair Of Topoisomerase Ii Dna Damage, Eric Goldstein Jan 2018

Analysis Of The Repair Of Topoisomerase Ii Dna Damage, Eric Goldstein

The Pegasus Review: UCF Undergraduate Research Journal

A large number of anti-cancer chemotherapeutics target DNA topoisomerases. Etoposide is a specific topoisomerase II poison that causes reversible double strand DNA breaks. This project analyses the repair of DNA damage induced by etoposide, a common anti-cancer chemotherapeutic. Through the comparison of two known DNA repair pathways, anti-cancer chemotherapy may become more cytotoxic. Double strand DNA break repair is mediated by either non-homologous end joining (NHEJ) or homologous recombination (HR). NHEJ repairs through direct ligation of a double stranded break, whereas HR utilizes a homologous template to recover the wild type sequence. Reporter cassettes involving the expression of green fluorescent …

Cold Temperature Effects On Byssal Thread Production By The Native Mussel Geukensia Demissa Versus The Non-Native Mussel Mytella Charruana, Sasha Brodsky Jan 2018

Cold Temperature Effects On Byssal Thread Production By The Native Mussel Geukensia Demissa Versus The Non-Native Mussel Mytella Charruana, Sasha Brodsky

The Pegasus Review: UCF Undergraduate Research Journal

Mytella charruana is a Central/South American mussel that has been found as an introduced species along the southeastern Atlantic coast of the United States since 2004. Previous experiments have determined the lethal thermal minimum of M. charruana to be between 6-9° C. Continuous byssal thread production is essential for mussel survival as it is used for attachment to substrates in natural environments, but may decrease when environmental conditions deviate from their optimum. We sought to determine whether M. charruana exhibits a non-lethal, thermal response involving a reduction in byssal thread production. Mytella charruana and, for comparison, a native mussel species, …

F. Scott Fitzgerald As A "Hot Nietzschean": The Influence Of Friedrich Nietzsche's Philosophy In This Side Of Paradise, The Beautiful And Damned, And The Great Gatsby, Lindsey Carman

Electronic Theses and Dissertations

Beginning in 1915, F. Scott Fitzgerald was exposed to the ideas of Friedrich Nietzsche under the guidance of mentors and from his personal reading lists. While reading Nietzsche, Fitzgerald's concern with the rise of cultural pessimism in 1920s America appeared in his fiction. Interestingly, both the philosopher and author explore the decline of Western culture in the twentieth century––a period of identity crises that affected America and Europe. This thesis investigates Fitzgerald's misreading of Nietzschean ideas that appears in his fiction to highlight the author's interest in explaining the cause of America's decline.

Categorical Change: Exploring The Effects Of Concept Drift In Human Perceptual Category Learning, Andrew Wismer Jan 2018

Categorical Change: Exploring The Effects Of Concept Drift In Human Perceptual Category Learning, Andrew Wismer

Electronic Theses and Dissertations

Categorization is an essential survival skill that we engage in daily. A multitude of behavioral and neuropsychological evidence support the existence of multiple learning systems involved in category learning. COmpetition between Verbal and Implicit Systems (COVIS) theory provides a neuropsychological basis for the existence of an explicit and implicit learning system involved in the learning of category rules. COVIS provides a convincing account of asymptotic performance in human category learning. However, COVIS – and virtually all current theories of category learning – focus solely on categories and decision environments that remain stationary over time. However, our environment is dynamic, and …

Studies Of Norspermidine Uptake In Drosophila Suggest The Existence Of Multiple Polyamine Transport Pathways, Michael Dieffenbach Jan 2018

Studies Of Norspermidine Uptake In Drosophila Suggest The Existence Of Multiple Polyamine Transport Pathways, Michael Dieffenbach

Honors Undergraduate Theses

Polyamines are a class of essential nutrients involved in many basic cellular processes such as gene expression, cell proliferation, and apoptosis. Without polyamines, cell growth is delayed or halted. Cancerous cells require an abundance of polyamines through a combination of synthesis and transport from the extracellular environment. An FDA-approved drug, D,L-α-difluoromethylornithine (DFMO), blocks polyamine synthesis but is ineffective at inhibiting cell growth due to polyamine transport. Thus, there is a need to develop drugs that inhibit polyamine transport to use in combination with DFMO. Surprisingly, little is known about the polyamine transport system in humans and other eukaryotes. Understanding the …

A Machine Learning Approach To Assess The Separation Of Seismocardiographic Signals By Respiration, Brian Solar Jan 2018

A Machine Learning Approach To Assess The Separation Of Seismocardiographic Signals By Respiration, Brian Solar

Honors Undergraduate Theses

The clinical usage of Seismocardiography (SCG) is increasing as it is being shown to be an effective non-invasive measurement for heart monitoring. SCG measures the vibrational activity at the chest surface and applications include non-invasive assessment of myocardial contractility and systolic time intervals. Respiratory activity can also affect the SCG signal by changing the hemodynamic characteristics of cardiac activity and displacing the position of the heart. Other clinically significant information, such as systolic time intervals, can thus manifest themselves differently in an SCG signal during inspiration and expiration. Grouping SCG signals into their respective respiratory cycle can mitigate this issue. …

Olfaction, Memory, And Presence In Warfighters: Do The Scents Of War Matter?, Benson Munyan

Electronic Theses and Dissertations

Background: Exposure therapy (EXP) is a first-line intervention for combat-related PTSD. EXP works by repeatedly exposing the patient to the feared stimuli, situation, or physical sensations in the absence of actual danger until the stimuli no longer evoke maladaptive responses. Over the past decade, multiple technologies have been introduced to augment the EXP process by presenting multi-sensory cues (e.g., sights, smells, sounds) to increase patients' sense of presence. Exploratory research has only broadly examined the effect of odorants on the patient's sense of presence during simulated exposure tasks. This study hypothesized that those with autobiographical memories similar to the virtual …
