Design And Creation Of A Device To Induce Vergence Eye Movements, Jacob B. Jaminet, Paul A. Wetzel

UROP Posters

Automated eye-tracking systems can detect and analyze eye movements as a means to accurately diagnose more than 20 neurological diseases including mild traumatic brain injury. Mild traumatic brain injury is an occurrence of injury to the head resulting from blunt trauma or from acceleration or deceleration forces. Eye movement refers to the voluntary or involuntary movement of the eyes, helping in acquiring, fixating and tracking visual stimuli. There are three types of voluntary eye movement to track objects: smooth pursuit, vergence shifts and saccades. Vergence shifts are eye movements where the eyes move in opposite directions: moving to the midline …

Realistic Spiking Neuron Statistics In A Population Are Described By A Single Parametric Distribution, Lauren Crow 9370373

UROP Posters

The spiking of activity of neurons throughout the cortex is random and complicated. This complicated activity requires theoretical formulations in order to understand the underlying principles of neural processing. A key aspect of theoretical investigations is characterizing the probability distribution of spiking activity. This study aims to better understand the statistics of the time between spikes, or interspike interval, in both real data and a spiking model with many time scales. Exploration of the interspike intervals of neural network activity can provide a better understanding of neural responses to different stimuli. We consider different parametric distribution fitting techniques to characterize …

The Role Of Soviet Invasion Of Afghanistan In The Breakdown Of The Ussr, Ezoza Nomazova

UROP Posters

The collapse of the Soviet Union in 1991 was one of the biggest historic events of XX century. Much like the Roman Empire, the USSR breakdown was due to an aggregate of factors, some internal, and some foreign. Unlike, the Roman Empire, the Soviet Empire collapsed suddenly. Among the reasons for the fall of the Union, the invasion of Afghanistan was one of the poorest decisions that was made by the Soviet government. What factors did this event contribute to the fall of the USSR?

The Russian invasion of Afghanistan had big impact on the attitude of the developing countries …

Androgen Mediation Of Elaborate Male Traits: The Effects Of Dihydrotestosterone Administration On Vocal Quality In Male Green Treefrogs, Hyla Cinerea, Thor M. Goodfellow

Honors Theses

Elevated androgen levels are well known to mediate the expression of male courtship behaviors and elaborate traits, but whether androgens act via threshold or graded effects is less clear. Models linking elaborate male traits to the endocrine system often assume that androgens have a graded effect on the magnitude or extent of elaborate male traits and that female preference for more elaborate male traits thus drives concordant directional selection on circulating androgen levels. To test this hypothesis, I examined the effects of dihydrotestosterone (DHT) administration on the quality of advertisement calls produced by male Hyla cinerea. Advertisement calls are an …

Combination Of Music And Aromatherapy To Improve The Efficiency Of Motor Functions And Speech In Patients Paralyzed From Stroke., Mounica Bevara

UROP Posters

With the rapid development of medical technology, millions of dollars are being spent on discovering innovative methods of treating fatal diseases such as stroke that may also result in temporary paralysis. Physiotherapy treatments aimed at restoring brain function in patients paralyzed following a stroke is subjective to the patient and does not guarantee complete rehabilitation. While many practitioners have attempted to employ complementary and alternative methods of treatment such as massage therapy, acupuncture therapy, siddha, and marma therapy, none of them proved to be equally as effective as physiotherapy. However, prior studies support the notion that aromatherapy used in combination …

Parent And Administrator Perceptions Of A Parents As Teachers Program (Pat) In Petal, Mississippi, Victoria Roseanne Jones

Honors Theses

This thesis is about the perceptions of the Parents as Teachers (PAT) Program in Petal, Mississippi. In order to gauge these perceptions, I developed a survey for the parents in the program and a survey for the parent educators (program administrators). The parent surveys were administered during home visits and the administrator surveys at a monthly staff meeting. I used thematic coding to analyze the qualitative data and SPSS for the quantitative data. I found that the administrators had accurate perceptions about the parents' income and marital status, but not their age. The parents and administrators were very satisfied with …

Do You See What I See? How A Dark Triad Personality Affects Perceptions Of Dark Triad Characters In Film And Television, Timothy Davis

Honors Theses

The Dark Triad is composed of three related subclinical personality traits: narcissism (excessive self-love, need for attention), psychopathy (cold, remorseless), and Machiavellianism (manipulative, cynical). The present study uses Dark Triad film/television characters to examine how Dark Triad people view others like them. It was hypothesized that (1) participants higher in the Dark Triad are more interested in films/television shows with Dark Triad characters, (2) participants higher in the Dark Triad have a more positive reaction to Dark Triad characters, and (3) Dark Triad participants see themselves in Dark Triad characters. Gender differences in Dark Triad character evaluations were also examined. …

Redefining The Insular Tradition: Illuminated Manuscripts Of The Seventh Through Ninth Centuries, William Boyles

Honors Theses

During my studies as an undergraduate student with an interest for medieval art, I found myself drawn to the beautifully painted works of illuminated manuscripts. Especially interested in the history, culture, and tradition of the British Isles, I became intrigued by the oftentimes-interchangeable term Insular. Textbooks, scholars, and various journal articles that I read all viewed Insularity in a slightly different light. So when given the chance to explore a unique topic for my honors thesis, I immediately knew that I had to research this problematic designation. My research began with a broad reading of the core of books, journals, …

A Raman Spectroscopic And Computational Study Of The Effects Of Halogen Bonding On Pyrimidine Containing Systems, Peyton Lindsey Reves

Honors Theses

This thesis involves the study of the effects of halogen bonding on pyrimidine containing systems. Halogen bonding is a type of non-covalent interaction that can occur when a Lewis base interacts with an iodine, bromine, or chlorine atom in a second molecule. The phenomenon of halogen bonding is explained by the presence of a localized region of positive electrostatic potential that exists on the halogen. This positive region is referred to as the σ-hole, and gives halogen bonding its other common name, σ-hole bonding. The magnitude of the positive σ-hole depends on both the type of halogen molecule involved in …

Delivery Of A Fatty Acid Signal Via Rtil For Biofilm Dispersion, Rachaud M. Keyes

Honors Theses

A number of proposed applications for ionic liquids involve ionic liquid/water interfaces, such as, chemical separations or drug delivery systems. Therefore, an understanding of the solubility and micellar behavior of ionic liquids in an aqueous environment is critical fundamental knowledge. The long term goal of our study was ionic liquids for delivery of biological active agents; therefore, we chose the anion, bis(trifluoromethanesulfonyl)imide (Tf2N) since it promotes water stability and forms water immiscible RTILs. The study then paired the Tf2N-anion with three different classes of cations. By adding apolar substituents (-CH2-) to the cation, the size of the molecule increases in …

A Computational Comparison Of The Hydrophobic Pocket Of Neural And Epithelial Cadherins For The Purpose Of Identifying A Selective Inhibitor, Ross E. Straughan

Honors Theses

Classical cadherins are a subfamily of calcium-dependent cellular adhesion molecules that play an important role in the formation of cellular junctions in many tissues. The extracellular portion of cadherins consists of five tandem-repeated domains (EC1-EC5). The critical first step in cadherin-mediated cellular adhesion occurs at the interface between two adjacent EC1 domains in which the transition from monomer to dimer is accomplished by docking the W2 residue of the N-terminal β-strand of one EC1 domain into the hydrophobic pocket of its partner domain. Cancer and many other diseases have been linked to the aberrant expression of Epithelial (E-cad) and Neural …

Properties Of A Fluorescent Deoxycytidine Analog In I-Motif Dna, Sara E. Wingate

Honors Theses

Experiments to determine fluorescence lifetimes and fluorescence quenching constants were performed using oligonucleotides of DNA containing PdC, a fluorescent analog of cytidine, at five different locations in the i-motif. My experiments were chosen in order to better understand the structural characteristics of i-motif DNA, which are thought to have biological importance in cancer and drug delivery. Fluorescent lifetime experiments were carried out using an ISS K2 fluorescence instrument with a modulated LED light source in order to determine if the cytidine bases in DNA replaced by PdC were paired or unpaired in the i-motif structure. The resulting data allowed us …

The Fall Of Teotihuacan, Elizabeth P. Ale

UROP Posters

In this project I present a survey of multiple theories regarding the dissolution of the ancient Mesoamerican city of Teotihuacan. This complex city-state was established around 100 BCE and became one of the largest and most powerful sites in Mesoamerica. Located about 25 miles northeast of what is today known as Mexico City, Teotihuacan was home to many advanced technological and social structures, including a pyramid called The Pyramid of the Sun that boasted a base as large as the Great Pyramid of Giza’s. At some time between the 7^th and 8^th century CE, Teotihuacan went into decline. …

Decreased Pain Severity And Differential Gene Expression Following Calmare Therapy, Jeffrey Petraco, Angela R. Starkweather, Amy Heineman

UROP Posters

We present the results of a double-blinded randomized sham-controlled research study of a non-pharmacologic low back pain intervention. Calmare therapy is an neurocutanous electrical stimulation approach for pain management. The intervention group received Calmare therapy and the other received sham. Differences in pain severity and interference scores, pain sensitivity measures and gene expression profiles are reported. Patterns of downregulated gene expression suggest that Calmare may alter proteins involved in pain transduction may have implications for the treatment of other chronic pain conditions.

Physician Role In Enhancing Patient Communication, Tamanna Sahni

UROP Posters

Communication in the in-patient environment is crucial, and the relationship between a patient and physician enhances patient health and wellness. Patients should feel confident with their abilities to feel comfortable conversing with physicians, which would thus treat symptoms more effectively. This communication has decreased over time, hence patients are often are unable to obtain medical information from their healthcare providers. What is the relationship between psychological factors, such as self-esteem, and quality of patient-physician communication? And can physicians ensure increased patient comfort in the medical environment?

Various factors can affect the patients’ comfort with their physicians, and when addressed, these …

Asthma-Related Anxiety And Quick-Relief Medication Use In Urban Children With Asthma, Sarah E. Astrab, Robin Everhart

UROP Posters

Among children, asthma is the most common chronic illness. Although not curable, asthma is manageable with the use of both daily controller medication and quick relief or rescue medication. Anxiety has been found to increase asthma symptoms in children. Caregivers who are anxious about their child’s asthma symptoms may perceive their child’s asthma as more severe or doubt their ability to manage their child’s asthma, which can result in the misuse of asthma medication. This study focused on the association between asthma-related anxiety and the use of quick-relief asthma medications in a low-income, urban sample in Richmond, Virginia. Child participants …

Queer-Baiting On The Bbc’S Sherlock: Addressing The Invalidation Of Queer Experience Through Online Fan Fiction Communities, Cassidy Sheehan

UROP Posters

Fans of a particular media source often write fan fiction to build on, deviate from, and transform original source material. The BBC’s Sherlock is not exempt from this common practice; in fact, the homoerotic subtext which persistently endures within the show lends itself to the production of slash fan fiction. Many perceive this subtext as a method of queer-baiting, or an ultimately harmful tactic used by writers and producers to lure in queer viewers. In this paper, dialogue and scenes from the show itself are compared to excerpts from works of fan fiction in order to explore reactions to queer-baiting …

The purpose of this study was to examine language acquisition and development in multiple birth children compared to singleton children in order to examine how decreased maternal sensitivity amongst mothers of multiple compared to mothers of singletons affects language acquisition skills in children.. The first phase of research for this study started with research on maternal sensitivity, specifically differing levels of it amongst mothers of different types of children, either by singletons of multiples, and potential causes for these differing levels of maternal sensitivity. The second phase focused on language skills of multiple and singletons at a young age and …

The Increase On Nonconsensual Bride Kidnapping In Kyrgyzstan, Amna Nawaz

UROP Posters

Since the fall of the Soviet Union, the country of Kyrgyzstan has had an unprecedented jump in bride kidnapping. The number of occurrences has skyrocketed and with that so has the severity of the violence. In this time women are taken, with no prior indication of when or how, and forced to marry their kidnappers. This non-consensual practice has morphed for reasons unknown. To stop the increasingly abysmal state of women’s rights in Kyrgyzstan, and in countries all of over the world, we must discover why people turned towards violence and lack of consent in the 1990’s.

Modeling Atp-Binding Cassette G2 (Abcg2) Substrate Specificity, Raghav D. Acharya, Aurijit Sarkar, Glen E. Kellogg

UROP Posters

How well can we predict efflux by ATP-binding cassette G2?

It is estimated that there will be about 1.6 million new cases of cancer and half a million cancer deaths in the US during 2015.ATP-binding cassette (ABC) efflux transporters such as ABCG2 are overexpressed in chemotherapy-resistant cancer cells. Anticancer drugs are prone to efflux by these transporters. Being able to identify drugs that are effluxed is of great interest in drug discovery.The current arsenal of methods used to detect efflux are not easily adaptable to high throughput formats and are limited in scope, making experimental analysis an expensive prospect. Hence, …

Stand-Up Comedy And Self-Deprecating Humor, Amelia M. Bell

UROP Posters

Stand-up comedy has been around for centuries, making people laugh for generations. Through the years the forms and techniques stand-up comedians use have shifted back and forth. Self-deprecation humor is one of these forms of humor, where the comedian pokes fun at his or herself, and it has recently become more incredibly popular in today’s society. Stand-up comedians like Louis C.K. have risen to newfound popularity by using self-deprecating humor almost completely in their sets. This paper attempts to answer the question of why audiences respond so positively to stand-up comedians who use self-deprecating humor. It does so by arguing …

Narco Trafficking, Corruption, And Perpetuated Violence In Guatemala, Ima T. Haque

UROP Posters

ABSTRACT: Narco-trafficking and Perpetuated Violence in Guatemala

Over the years drug cartels have made their way into Guatemala through their borders. Drug trafficking is the main reason why the border between Guatemala and Honduras is one of the most violent locations in Central America. Due to lawlessness and corruption, wealthy drug traffickers assume an authoritative role in the region (Crisis Group, 2014). A 2010 report done by U.S. International Narcotics Control Strategy says that “Guatamala is the epicenter of the drug threat.” (Brice, CNN, 2011). However, the increase in drug related violence is due to Zetas, a Mexican drug cartel. …

Means and Katherine Ridgway. The purpose of my research was to conduct a comparative study between the virtual and physical process of mending, or repairing, artifacts. I was granted access to three different vessel fragments which were improperly mended in the 1960s. It was my goal to remove the previous adhesive adhered to the sherds and replace it with a safer adhesive. Simultaneously, I brought the previously mended sherds …

Increasing Vaccination Rates In Children Of Vaccine-Hesitant Parents, Keegan G. Edgar

UROP Posters

In recent years, the number of parents who have declining vaccinations or instituting altered immunization schedules for their children has risen. This has caused an increased number of outbreaks of vaccine-preventable diseases. It has also threatened herd immunity, which provides a measure of protection for those who are susceptible to disease given enough people are vaccinated, as this hinders the spread of the disease. To combat this threat to herd immunity, it is becoming increasingly necessary to find a solution to the problem of increasing personal belief exemption.

I took a cause and effect approach in the way I researched …

Icp-Oes Analysis Of The Chemical Composition Of Hypergolic Mixtures, Monique Jones

UROP Posters

Hypergolic mixtures involve a chemical reaction between an oxidant and a fuel source. These reactions are self-igniting and can be performed using common household materials. The ease of access to the reactants, and delayed ignition have increased the occurrence of hypergolic mixtures in arson-related crimes and incendiary devices. Currently, few chemical signatures exist to link hypergolic residues to a perpetrator. This makes it difficult to obtain forensically relevant information from evidence during an investigation. A hypergolic reaction of interest to forensic laboratories involves combustion between a glycol-based fuel source and potassium permanganate. Past studies have determined that one can distinguish …

Anxiety Reactivity In Monozygotic Twins Discordant For Major Depression, Sravya Uppalapati

UROP Posters

Transient anxiety is a healthy response to stress. However, constant anxiety elicits negative responses and threatens an individual’s day-to-day living. The onset of anxiety disorders excluding specific phobias is often childhood to late adolescence or early adulthood. Though depression is characterized as a low-energy state unlike anxiety, there is a high concordance between anxiety and depression. “Nearly one-half of those diagnosed with depression are also diagnosed with an anxiety disorder” (“Facts and Statistics”). There are two goals of the study:

1. To compare the individual response levels between monozygotic (MZ) twins discordant for major depressive disorder (MDD) during an anxiety-provoking …
