Because You're A Good Man... Right?: A Deconstructive Analysis Of Flannery O'Connor's "A Good Man Is Hard To Find", Dan Abella Apr 2012

Because You're A Good Man... Right?: A Deconstructive Analysis Of Flannery O'Connor's "A Good Man Is Hard To Find", Dan Abella

Undergraduate Student Symposium

The meaning and “correct” use of semantic opposites––up:down, male:female, black:white, and good:evil, for example––seem obvious and uncontested in casual speech. Yet the understanding of such pairs remains anything but simple according to deconstructionist critical theory. Founded by French philosopher Jacques Derrida, deconstruction, employed as a literary and linguistic analysis, revels in the uncertainty of language, especially in the dynamic “play” of binary opposites. Hence, Derrida's theories broaden the possibilities of meaning in speech and writing by refusing to ascribe absolute referents to words. Flannery O'Connor's landmark short story “A Good Man Is Hard to Find” thoroughly meditates on …

Bilingual Text Comprehension, Irina Cossio, Belkis L. Rivas Apr 2012

Bilingual Text Comprehension, Irina Cossio, Belkis L. Rivas

Undergraduate Student Symposium

There are competing theories regarding how bilingual individuals process language. The language selectivity view suggests that bilinguals only activate the language being used at that moment; therefore only one language is active in the brain at once. Other views, such as the language non-selectivity view, suggest that both languages are activated regardless of which language may be in use. Recent studies have provided evidence that both languages may be activated depending upon the context. Context is important because research examining monolinguals has shown that the left hemisphere is associated with processing contextually appropriate words such as inferences strongly implied by …

Biomechanical Justification For Training Rowers With The Power Clean, Jada Buckner, Anamaria Cretu, Kyle Gyarfas Apr 2012

Biomechanical Justification For Training Rowers With The Power Clean, Jada Buckner, Anamaria Cretu, Kyle Gyarfas

Undergraduate Student Symposium

The main objective when training athletes is to base strength and conditioning programs on the needs and goals of the athlete and the team. This ensures that programs are sport-specific. The power clean (a specific strength training exercise) is seen by coaches as mimicking the technique and demands of the rowing stroke itself, and thus is commonplace in the strength and conditioning programs of rowers. However, the power clean has not been formally or biomechanically justified for specificity of training with rowers. The purpose of this study is compare body technique and muscle use between the power clean lift and …

Bridget Jones: Post Feminist, Or Frantically Fawning?, Alison Parente

Undergraduate Student Symposium

This essay contrasts Helen Fielding’s ‘Bridget Jones’s Diary’ to Jane Austen’s ‘Pride and Prejudice’ on the feminist aspects of both works. The piece argues that Austen’s protagonist Elizabeth Bennet is ironically more forward thinking in challenging gender stereotypes than Fielding’s Bridget Jones, though Elizabeth Bennet lived during a period of discrimination against women that imposed severe restrictions upon female lives.

Comparative Neurogenesis In The Brain Of The Adult Mayan Cichlid, Ahmed Ali, Kelsey Bragg, Catalina Breton, William Kotkin, Jonathan Romanes Apr 2012

Comparative Neurogenesis In The Brain Of The Adult Mayan Cichlid, Ahmed Ali, Kelsey Bragg, Catalina Breton, William Kotkin, Jonathan Romanes

Undergraduate Student Symposium

Neural progenitor cells are the only cells in the adult brain that continue to proliferate, migrate, and integrate into existing neural networks throughout the life-span of all mammals examined to date, including humans. Understanding how neurogenesis (the birth of new neurons) is regulated has exciting therapeutic potential for a wide range of central nervous system diseases. Neural progenitor cells exist in two neurogenic regions of the adult mammalian brain: the dentate gyrus of the hippocampus and the forebrain subventricular zone. In recent studies, postnatal neurogenesis has been reported in several regions of the fish brain including the olfactory bulb, optic …

Complete Protection And Glycosylation Of 5-Hydroxy-Dl-Lysine, Rina M. Bhalani, Lindsey Nowland Apr 2012

Complete Protection And Glycosylation Of 5-Hydroxy-Dl-Lysine, Rina M. Bhalani, Lindsey Nowland

Undergraduate Student Symposium

Adiponectin, a protein hormone, has been shown to play a role in preventing the development of atherosclerosis, a common cardiovascular disease. Altering some of the amino acids in adiponectin can provide beneficial effects towards that goal. One such amino acid, Hydroxylysine, can often undergo posttranslational modifications, such as glycosylation, the addition of a sugar molecule.

Hydroxylsine (Hyl) has the molecular formula of C6H14N2O3, and contains four functional groups: a hydroxyl group, a carboxylic group, and two amino groups. The ultimate goal of the proposed research is to galactosylate Hydroxylysine, that is, add …

How Math And Music Jams Together, Felicia Bell Apr 2012

How Math And Music Jams Together, Felicia Bell

Undergraduate Student Symposium

For centuries, mathematicians have been trying to analyze and model music. Music can be described and analyzed through quite a few equations which are based on trigonometric functions, derivatives and integration. A wave equation can be used to represent harmonic notes such as a vibrating string from a guitar. A single tone can be described by a sine function, while multiple notes played together can be described by the sum of each single tone. Processing a piece of music as a signal, the theory of Fourier Transform can identify each note and its amplitude or volume.

Lemuel, The Egocentric Human, Sasha Strelitz Apr 2012

Lemuel, The Egocentric Human, Sasha Strelitz

Undergraduate Student Symposium

This essay investigates Jonathan Swift’s Gulliver’s Travels, spotlighting a central message of his, warning humankind against the folly of vanity. Following his protagonist, Lemuel Gulliver, through four fantastical worlds, one begins to see a pattern of unwinding humanity. Before arriving in Lilliput (the first whimsical land), Gulliver is a typical human being, with typical hard-wired narcissism. After years of voyaging, and after a memorable stay with the Yahoos, Gulliver rejects his humanity as being brutish, vain, and egocentric. However, banished from Houyhnhnm Land, he finds solace and sanity in horse stables. Perhaps this seems excessive, but this reader attributes …

Loss Of 125i-Sarcosine1, Isoleucine8 Angiotensin Ii Binding In The Brain Of Neurolysin Knock-Out Mice, Jamala D. Swindle, Luz Gonzalez, Andrea Linares, Kira L. Santos

Undergraduate Student Symposium

The brain renin-angiotensin system profoundly affects the cardiovascular system, often with pathological consequences. However, many unresolved questions about its functionality remain. Recently it was shown that a novel, non-AT1, non-AT2 binding site for angiotensin II (Ang II) exists in the mammalian brain. This protein has been identified as the metalloendopeptidase neurolysin (E.C.3.4.24.16). To assess the localization of this binding site in mouse brain, 3 mice deficient in neurolysin as well as 3 wild-type mouse brains were evaluated for radioligand binding with 125I-Sarcosine1,Isoleucine8 Ang II (250 pM) in the presence of receptor-saturating concentrations of …

Mathematical Modeling, Simulation, And Compression Of Images, Jonathan Reyna Apr 2012

Mathematical Modeling, Simulation, And Compression Of Images, Jonathan Reyna

Undergraduate Student Symposium

This project builds a mathematical model that obtains parameters and statistical properties of residuals taken from a picture in JPEG format, to later simulate replicas of the original picture. The importance of this problem stems from the large amount of bandwidth required to transmit a high resolution picture over the Internet. The mathematical model built from this picture and its set of residuals has a much smaller magnitude than the original picture elements (pixels). This implies that if one were to transmit the parameters alone, a high compression rate would be achieved, thus saving bandwidth. In order to replicate the …

Population Densities Of Porites Sverdrupi, A Coral Limited To The Mexican Eastern Tropical Pacific, Eduardo Carrera Apr 2012

Population Densities Of Porites Sverdrupi, A Coral Limited To The Mexican Eastern Tropical Pacific, Eduardo Carrera

Undergraduate Student Symposium

Porites sverdrupi is a rare, endemic free living coral that only inhabits the Mexican Eastern Tropical Pacific at depths typically between 20 and 40 meters. Until recently it was considered an ecomorph of the more abundant congener Porites panamensis, so there are few studies focused solely upon this species. The volatility of the populations of corals in this region and a continually decreasing habitat has led some researchers to conclude that P. sverdrupi may be undergoing a natural process of extinction. This study initiates a multi-year analysis of the population trend of P. sverdrupi off the coast of Isla …

Porous Compounds As Drug Transfer Agents, Angelo J. Capobianco Apr 2012

Porous Compounds As Drug Transfer Agents, Angelo J. Capobianco

Undergraduate Student Symposium

For a while now there has been an interest in porous compounds to act as transfer agents for other compounds. Porous compounds are defined as such because the molecular structure of these compounds so as there is empty space, or a channel between each molecule of the compound. Therefore, the more molecules that the compound has, the more channels exist and the compound is more porous. The channels in these molecules allow molecules from other compounds, or guest molecules to become locked inside of the porous material. The compound being studied in this experiment is a solid, crystalline compound created …

The Epistemological Status Of Theoretical Simplicity, Yineth Sanchez Apr 2012

The Epistemological Status Of Theoretical Simplicity, Yineth Sanchez

Undergraduate Student Symposium

In this paper, I argue that theoretical simplicity is not an epistemic virtue. Therefore, we need not prefer the simpler explanation of two competing scientific theories. First, I clarify the concept of theoretical simplicity as it figures into discussions in the philosophy of science. Next, I evaluate the strongest arguments in favor of this view as a criterion of theory selection. Then, I present two instances where theoretical simplicity is not preferable as such a criterion. Lastly, I show that while there may be a number of nonepistemic criteria of theory choice, including simplicity, none of them bears upon truth. …

The Relationship Between Working Memory And Response Inhibition, Lauren Adames, Joe Cirno, Jacqueline Lefebre

Undergraduate Student Symposium

The purpose of this study is to determine whether two facets of executive functioning, working memory and response inhibition, are interrelated or independent. Working memory refers to the ability to acquire, manipulate, and retain information. Response inhibition refers to the ability to stop an ongoing action. In this experiment, we measured the working memory capacity of all participants using a traditional span-task. We then manipulated working memory load by having participants either count up (low load condition) or down (high load condition) while performing a stop signal task. In this task, participants were told to respond to a stimulus unless …
