Devaluing The Drachma, Tiffany Smith, Cory Levine Apr 2014

Devaluing The Drachma, Tiffany Smith, Cory Levine

Undergraduate Student Symposium

This research focuses on the downfall of the Greek economy and the economic crisis it produced years after joining the European Union. By abandoning the drachma and adopting the euro, Greece lost the ability to devalue its currency during times of large national debt. If Greece had chosen to remain with the drachma, it may have increased its likelihood of escaping a national economic crisis, which has caused the unemployment rate to escalate and fueled public unrest. This paper will also address the cause of Greece’s debt, the assistance it received from Goldman Sachs and similar banks, as well as …

Histological Analysis Investigating The Deepwater Horizon Oil Spill's Impact On Gut Tissue Of Crassostrea Virginica, Ji Hae Hwang, Timothy Chung Apr 2014

Histological Analysis Investigating The Deepwater Horizon Oil Spill's Impact On Gut Tissue Of Crassostrea Virginica, Ji Hae Hwang, Timothy Chung

Undergraduate Student Symposium

The Deepwater Horizon drilling rig explosion in 2010 led to the leakage of approximately 4.9 million barrels of oil from the Macondo well. The well was located about a mile under the water surface and its discharge covered a vast area of the northern Gulf of Mexico. Studies have shown that the presence of the oil, or the dispersants used after the incident, may have toxic effects on marine life. The eastern oyster, Crassostrea virginica, is an ideal species to analyze because it is a filter feeder; utilizing the gills for filtration and directing the food to the rest …

Literature And Medicine Courses: Examining Descriptions, Making Connections, Kamila Albert Apr 2014

Literature And Medicine Courses: Examining Descriptions, Making Connections, Kamila Albert

Undergraduate Student Symposium

The interdisciplinary field of “Literature and Medicine” aims to reintroduce the reflective study of literature into the scientific, data-driven world of healthcare. This broad subject allows for a range of teaching methodologies, often constructed in accordance with an instructor’s research or literary interests, which serve to make classes distinct. Notably, however, the language of “Literature and Medicine” course descriptions, which represent the most concise summaries of courses, often feature similar terms, concepts, and, at times, authors. This is not surprising when one considers that these carefully constructed descriptions must effectively bridge two very different subjects. Therefore, this research project evaluates …

Neural Stem Cells Proliferate In Vascular Niches In The Adult Mayan Cichlid Brain, Zara Khan, Jonathan P. Romanes, Sameed Ashfaq Apr 2014

Neural Stem Cells Proliferate In Vascular Niches In The Adult Mayan Cichlid Brain, Zara Khan, Jonathan P. Romanes, Sameed Ashfaq

Undergraduate Student Symposium

The birth of new neurons (neurogenesis) has been observed in all adult mammalian brains examined to date. Adult neural stem cells are located close to blood vessels in each of the two neurogenic regions observed in all mammals. A regulatory role for blood vessels has recently been suggested as a mechanism to regulate neurogenesis. Postnatal neurogenesis has been reported in several regions of the fish brain including the olfactory bulb, dorsal zones of the telencephalon, hypothalamus, and divisions of the cerebellum; however, little else is known about neurogenesis in the adult fish brain. Using thymidine analog incorporation assays, cell death …

Neurogenesis In Octopus Vulgaris, Jelileh Whitmore Apr 2014

Neurogenesis In Octopus Vulgaris, Jelileh Whitmore

Undergraduate Student Symposium

Cephalopods, particularly the octopus, have the largest and most complex invertebrate brains and show markers of behavioral complexity. Several mammalian studies have demonstrated a correlation between learning and neurogenesis (the birth of new neurons) in the hippocampus of the adult brain. The vertical lobe of Octopus vulgaris is thought to be analogous to the hippocampus of mammalian brain; however, neurogenesis has never been reported in the octopus. We used thymidine incorporation assays and immunostaining to demonstrate neurogenesis in the developed octopus brain. We are currently examining the proliferation, differentiation, integration, and cell death of newly born neurons in the octopus …

Next Generation Event Scheduling System, Jeremy Cantor Apr 2014

Next Generation Event Scheduling System, Jeremy Cantor

Undergraduate Student Symposium

Current event scheduling systems are often inefficient. Traditional business practices, such as employing office assistance to manually record event times requires the customer to languish needlessly on the telephone while waiting receive assistance and to repeat that process several times to establish just one appointment or a meeting. New software scheduling tools significantly reduces errors, yet they are still modeled after traditional processes. We have proposed to model scheduling as a “protocol” and use a visualization approach to depict the process. Using this protocol approach, the project includes analysis of the traditional scheduling processes. We have identified the inefficiencies that …

Sensation Seeking Behavior And Aggression: Predictors Of Low Physiological Arousal Under Stress, Jose Serrano, Mustari Akhi Apr 2014

Sensation Seeking Behavior And Aggression: Predictors Of Low Physiological Arousal Under Stress, Jose Serrano, Mustari Akhi

Undergraduate Student Symposium

Using the Bimodal theory of violence, aggression can be dissected into two distinct modes: affective violence and callous-unemotional violence (i.e. predatory violence) where the aggressor is physiologically “under-aroused” (Tulogdi, et al., 2012). These individuals also demonstrate sensation seeking behaviors as a way of increasing arousal. Combined, this suggests that sensation seeking behavior can serve marker of aggression and physiological under-arousal (Wilson and Scarpa, 2011). In order to test this idea, we examined the extent to which sensation seeking behavior was associated with physiological and self-report responses to acute stress (the cold pressor test, CPT). We found that sensation seeking behavior …

The Effect Of Physical Stress On Alpha Amylase Concentration In Saliva, Neil Thackar, Crystal Labozzetta Apr 2014

The Effect Of Physical Stress On Alpha Amylase Concentration In Saliva, Neil Thackar, Crystal Labozzetta

Undergraduate Student Symposium

Alpha amylase is an enzyme found in saliva, and is integral in the breakdown of large polysaccharides such as starch and glycogen. In addition, it also increases in response to physical stress, making it a useful indicator for pain threshold. In an attempt to determine the viability of using alpha amylase as a pain threshold indicator, alpha amylase concentrations were taken before and after an introduction to physical stress. 16 subjects (M= 22.13, SD= 5.67) were asked how sensitive they are to pain (high responder/low responder), and to rate the expected pain level (in response to the physical stress) on …

The Medical Care Costs Of Obesity, Natasha Madhyani, Michelle Mguyen

Undergraduate Student Symposium

The rate of obesity in the United States has been increasing drastically over recent decades. Obesity is defined through the body mass index of an individual, which is equal or greater to 30.0; more than twothirds of the population in the US is currently obese. There is an economic impact on the growing rate of obesity, with one of the main focuses in health care costs. There is a high chance of getting diseases that are linked with obesity (ex: hypertension, type 2 diabetes mellitus, and stroke). The annual medical spending for an obese individual can be six times as …

The Nba Draft: The Opportunity Costs Of Early Entry, Tiffany Kelly Apr 2014

The Nba Draft: The Opportunity Costs Of Early Entry, Tiffany Kelly

Undergraduate Student Symposium

From 1997 to 2010, the number of basketball, collegiate athletes to declare early entry into the NBA draft has significantly increased. The National Basketball Association created a rookie pay scale in the year 1995 that established a set amount players can receive during his rookie contract based on draft position. The rookie pay scale helped all1 teams to add new, unproven players at a reasonable price while keeping veteran players content with larger contracts. However, the pay scale not only created a distribution of salary, but also created more of an incentive for collegiate players to declare early entry …

Total Fms Scores Do Not Predicty Injury But Asymmetries And Low Individual Scores Do, Anya Ellerbroek, Stephanie Hauck Apr 2014

Total Fms Scores Do Not Predicty Injury But Asymmetries And Low Individual Scores Do, Anya Ellerbroek, Stephanie Hauck

Undergraduate Student Symposium

Functional Movement Screen (FMS) scores of <14 have been used to predict injury in athletic populations. Clinicians prioritize individual test scores of “1” and asymmetries when designing corrective exercise programs. Therefore, the presence of either of these may have more utility in predicting injury. The purpose of this study was to determine if the presence of a score of “1” or a left to right asymmetry in individual FMS tests would predict injury in collegiate athletes. 94 male and female collegiate athletes with no recent history of musculoskeletal injury performed the FMS during preseason. Injury incidence data were tracked for an academic year by each team’s certified athletic trainer via computer software. Injury was defined as physical damage to the body secondary to physical training and where the athlete sought medical care. Total FMS scores were categorized as low (<14) or high (>14). Pearson Chi-square analyses were used to determine if (a) total FMS scores could predict injury, and (b) the presence of “1” or an asymmetry could predict injury. Athletes with FMS scores of >14 were not any more likely to sustain an injury. However, athletes with individual scores of “1” or an asymmetry were 6.8x more likely to sustain an injury. Total FMS scores could not be used to predict injury in this group. However, the presence of a score of “1” or an asymmetry in the individual tests did predict injury. Individual test …

Unquestionable Misogyny In The Video Game Industry, Christopher Rosario Apr 2014

Unquestionable Misogyny In The Video Game Industry, Christopher Rosario

Undergraduate Student Symposium

Misogyny has moved from the silver screen, magazines, and internet into video gaming. The purpose of this essay is to demonstrate instances of gaming's misogynistic culture that began in the 1980's and has spiraled into the billion dollar juggernaut to this day. Countless examples of misogyny are expressed in gaming culture of the "hardcore" gaming market. Unfortunately, the gamers take their anti woman stances beyond the video games as well. When confronted about their misogynistic tendencies they attack with hateful words and pictures, and have even created a violent video game whose object is to assault a feminist blogger. Feminist …

Using An Engineered Trojan Horse To Kill Nematodes, Olena Bracho, Cyril Manchery Apr 2014

Using An Engineered Trojan Horse To Kill Nematodes, Olena Bracho, Cyril Manchery

Undergraduate Student Symposium

Infections due to parasitic nematodes result in nearly 125000 deaths annually. Strikingly, this rate remains nearly unchanged in the past 50 years likely owing to the fact that treatment options are either inefficient or inaccessible. Prior to infecting humans, most parasitic nematodes begin as larvae where they feed nearly exclusively on bacteria. This unique property may offer an opportunity to develop new biological control agents with the use of synthetic biology. In this study, we aim to develop gene circuit components that may be used to engineer Escherichia coli to act as a biological control agent of the model nematode …

You're Not As Dumb As You Think You Are: The Impact Of A Metacognitive Reframing Intervention, Matthew Welhaf, Deborah Radmanesh Apr 2014

You're Not As Dumb As You Think You Are: The Impact Of A Metacognitive Reframing Intervention, Matthew Welhaf, Deborah Radmanesh

Undergraduate Student Symposium

Working memory is the cognitive function responsible for maintaining and manipulating information. Working memory is related to other higher order cognitive abilities including, reading comprehension (Daneman and Merikle, 1996), reasoning (Kyllonen and Christal, 1990) and fluid intelligence (Conway, Kane, and Engle, 2003). Interventions designed to increase working memory are of great interest given the possible benefits in reading comprehension and academic performance. Metacognition refers to knowledge regarding one’s own cognition and ability to monitor cognitive functioning (Flavell, 1979). Interventions designed to reframe metacognitive interpretations of subjective task difficulty have been shown to improve cognitive performance (Autin and Croizet, 2012). One …

A Survey Of The Cost-Benefit Analyses Of Uninsurance, Prasanna Marathe Apr 2014

A Survey Of The Cost-Benefit Analyses Of Uninsurance, Prasanna Marathe

Undergraduate Student Symposium

Health care spending is carving up an increasing share of the US national gross domestic productapproximately 18%- but the absolute number-46 million- and the proportion of uninsured Americans15%- are also on the rise (McConnell, Microeconomics: Principles, Problems, and Policies, 2012). These counterintuitive trends are alarming and cannot be sustained without significant net economic costs. A survey of the cost-benefit analyses of uninsurance reveals that uninsurance has tremendous opportunity costs (ex: foregone economic productivity and higher mortality) and is economically (net) harmful. It also reveals that extending insurance to currently uninsured will be economically (net) beneficial to our nation as a …

An Incompatible Romance, Grace Ducanis Apr 2014

An Incompatible Romance, Grace Ducanis

Undergraduate Student Symposium

This presentation examines the heroine and hero of Jane Austen’s novel Northanger Abbey, exposing their inequality in temperament, intelligence, and discernment, while questioning the true motivations for their attachment. Catherine Morland and Henry Tilney are not separated by wealth, class, or other social expectations, but by their critically dissimilar personalities. Although Catherine is inferior to Tilney in every sense, the novel promotes the couple’s romance and marriage. Tilney’s affection does not stem from his acceptance of Catherine as an equal, but from his perception of her affection for him. This paper explores the polarity of the two characters in light …

Attractiveness Perception: Contemporary And Classic, Scott Earley, Shannon Ali-Samhoul Apr 2014

Attractiveness Perception: Contemporary And Classic, Scott Earley, Shannon Ali-Samhoul

Undergraduate Student Symposium

People have noticed that less attractive mates seem more attractive near the end of the night. Most blame alcohol consumption, but studies have shown (Johnco,C; Wheeler,L, 2010), (Sprecher, S; DeLamater, J; Neuman, N, 1984) that it is actually the reduction of the dating pool that creates the illusion of attractiveness. The focus of this study is to examine the perception of attractiveness people have when there is a reduced population of viable mates. One interpretation suggests that the perceived increase of attractiveness acts as a means to lower the standards of the yet unaware perceiver. There are certain set points …

Predicting Porphyrin Basicity Using Semi-Empirical Methods, Haley Mckissack Apr 2014

Predicting Porphyrin Basicity Using Semi-Empirical Methods, Haley Mckissack

Undergraduate Student Symposium

Porphyrins are macrocycles found in many natural compounds. The changes in energy between the protonated (dication) and free base porphyrins were determined using molecular modeling. The data obtained was then compared to experimental enthalpy values. The porphyrins analyzed were octaethylporphyrin, octaethyltetraphenylporphyrin, tetraphenylporphyrin, and tetra-[2]-pentylporphyrin. Molecular mechanics was employed to optimize each porphyrin, and semi-empirical calculation methods RM1 and PM3 were subsequently utilized to test the conformational energies of the protonated and deprotonated porphyrins. The semi-empirical PM3 method was best for analysis of energy changes among the porphyrins; although the obtained values did not exactly match experimental values, the trends of …

A Case Report Of Improving Running Biomechanics Through Movement Pattern Training In A Female Competitive Runner, Anya Ellerbroek, Stephanie Hauck Apr 2014

A Case Report Of Improving Running Biomechanics Through Movement Pattern Training In A Female Competitive Runner, Anya Ellerbroek, Stephanie Hauck

Undergraduate Student Symposium

Running-related musculoskeletal injuries occur with an overall yearly incidence rate between 37 and 65%. Most are lower extremity with 50-75% of all running injuries classified as overuse. These injuries have been linked to faulty running biomechanics such as foot over pronation, and excessive hip adduction and internal rotation. Therapists have primarily focused on strengthening the hip muscles to prevent excessive motion. However, little evidence supports the efficacy. This case outlines the use of functional movement pattern training rather than isolated muscle training to improve faulty biomechanics. The participant was a 19 year old female competitive distance runner with a history …

Analysis By Gcms Of Flavone Isomers In Pancreatic Cancer Cells, Daniela Fernandez Apr 2014

Analysis By Gcms Of Flavone Isomers In Pancreatic Cancer Cells, Daniela Fernandez

Undergraduate Student Symposium

Flavone A and B were found to be cytotoxic in pancreatic and colon cancers. Both work in triggering cell apoptosis, although the mechanism and relationship between structure and function are unknown. They are similar in structure, only differing in the location of a hydroxyl and methoxyl group. Flavone B is more planar and lipophilic and, in contrast to Flavone A, has been found to selectively induce apoptosis in less differentiated cancer cells. In this study, the goal was to trace flavone uptake by pancreatic cancer cells and its dispersion inside to determine whether apoptosis is caused in the nucleus or …
