Attitudes Towards Business Ethics: A Study Of Austrian Student Views, Dominique Wimmer
Attitudes Towards Business Ethics: A Study Of Austrian Student Views, Dominique Wimmer
Undergraduate Student Symposium
The Attitudes Towards Business Ethics Questionnaire (ATBEQ) has been used extensively to measure respondent views towards ethical business philosophies and situations. This study reports the ATBEQ survey results for a sample of 171 Austrian students. Results indicate that Austrian students believe that while morality is important in the business environment, the business world operates under its own set of rules. This thinking fits with an ethical business philosophy leading towards Machiavellianism. In addition, Austrian respondents reported support for an unethical decision, which unfairly favors the individual financially at the expense of an insurance company. These and other results are discussed …

Bilingual Text Comprehension, Irina Cossio, Belkis L. Rivas
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 …
Complete Protection And Glycosylation Of 5-Hydroxy-Dl-Lysine, Rina M. Bhalani, Lindsey Nowland
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 …
Examining Relationships Of Transferrin Adhesion To Hilafilcon, Omafilcon, And Tisifilcon A Contact Lenses, Darshan Solanki
Examining Relationships Of Transferrin Adhesion To Hilafilcon, Omafilcon, And Tisifilcon A Contact Lenses, Darshan Solanki
Undergraduate Student Symposium
Lacrimal glands adjacent to the eye secrete tear proteins that deposit onto contact lenses. In order to study this process, three types of FDA group II contact lenses fabricated from hilafilcon, omafilcon and tisifilcon A were incubated in 2.0 mg/mL solutions of holo-transferrin for 1, 2, 3 and 4 days. The degree of protein adhesion was determined by bicinchoninic acid assay. Transferrin adhered to hilafilcon contact lenses in an increasing pattern from day 1 to day 3, with a decrease on day 4. Transferrin adhesion to omafilcon contact lenses followed the same trend with greater protein adhesion than the …

How Math And Music Jams Together, Felicia Bell
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.

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 …

Role Of Mesenchymal Stem Cells In Chronic Wound Healing, Shahjahan Shareef
Undergraduate Student Symposium
Stem cells has been well characterized to be multipotent cells that can differentiate into multiple tissueforming cell lineages, as osteloblasts, adipocytes, chondrocytes, tenocytes and myocytes. It has been shown that bone marrow derived cells provide stem and progenitor cells to wounds during inflammation, proliferative and remodeling phase of wound healing. On the other hand, mice have become the premier animal model for the study of numerous complex human diseases. Mouse models are cost effective and have a favorable generation time for cross breeding experiments. In our work we show the use of two mice models to determine which is the …
The Different Shades Of Black, Charnele Michel
The Different Shades Of Black, Charnele Michel
Undergraduate Student Symposium
“Different Shades of Black” is a short documentary film about the ongoing conflict between lightskinned and dark-skinned people in the black community. This is a controversial issue among people of African-American and Caribbean descent, some of whom believe that lighter-skinned black people are considered more attractive, and often receive better opportunities, than darker-skinned black people. Such stereotypes about skin complexion may be fueled by the media (e.g., music videos, movies, television shows, and advertisements). This documentary will showcase the opinions of people in the black community about this issue. The goals of this film are to bring awareness to this …
The Effects On The Uv Spectra Of H2Poh-Tphp As Dication And Dianion Formation Occurs, Yadira Barreiro, Priya Mohan, Alexis Otero
The Effects On The Uv Spectra Of H2Poh-Tphp As Dication And Dianion Formation Occurs, Yadira Barreiro, Priya Mohan, Alexis Otero
Undergraduate Student Symposium
Porphyrins differ in the nature of their peripheral substitution; β substituted are known as natural porphyrins and meso substituted as synthetic porphyrins. Within the meso substituted porphyrins we studied the H2pOH-TPhP. The UV absorption spectra of this porphyrin is observed and monitored between 350 and 750 nm. The resulting absorption spectra after the creation of the dianion and dication with the respective titrations using NaHCO3/HCl and NaOH/HCl will be explained based on the position of the OH in the phenyl group and contribution to the formation of the respective dication or dianion.
The Proposal: Show Her Who's Boss, Alison Parente
The Proposal: Show Her Who's Boss, Alison Parente
Undergraduate Student Symposium
This essay identifies the romantic and screwball comedy elements within the film The Proposal, while simultaneously relating the motion picture to women's issues. This piece argues that though The Proposal is eclectic in style, it is ultimately a film that proposes nothing new to audiences, and in fact is regressive in nature with respect to its reinforcement of clichéd gender roles and stereotypes.
The Relationship Between Working Memory And Response Inhibition, Lauren Adames, Joe Cirno, Jacqueline Lefebre
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 …

Porous Compounds As Drug Transfer Agents, Angelo J. Capobianco
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 Effects Of Sleep Deprivation On Neurophysiological Measures Of Emotion And Biochemical Measures Of Stress, Ramey Alfarra
Undergraduate Student Symposium
The relationship between sleep and emotion is not well understood. Existing studies typically link sleep and emotion based on subjective assessments- rarely are objective measures utilized to examine the interaction between sleep and emotion. Here, we determined the effect of 24 hours of sleep deprivation on a neurophysiological measures of attention to emotional stimuli through the use an electroencephalographic (EEG) event related potential (ERP) measure of emotion- the late positive potential (LPP). Each participant underwent two testing sessions between 7:00-9:00 am: the first session occurred five days prior to sleep deprivation (baseline testing), the second session occurred the morning after …
The Effects Of Stress And Sleep Restriction On Attention And Inhibitory Task Performance, Brandi Viparina, Isaac Chayo
The Effects Of Stress And Sleep Restriction On Attention And Inhibitory Task Performance, Brandi Viparina, Isaac Chayo
Undergraduate Student Symposium
Stress and sleep deprivation impairs performance on attention and inhibitory tasks. Due to the bidirectional effects of sleep restriction and stress, it is difficult to determine the combined and independent effect of each of these on cognitive performance. In an effort to disentangle the unique contribution of stress and sleep on performance, we sought to examine students during a time in which they are both sleep restricted and stressed. To that end, we employed a repeated measures withinsubject design in which each participant was tested twice, once during a non-exam week and once during exam week. The Stroop and a …

Regular yeast growthmedia, plus low (10 tsp/100 pounds), medium (34 tsp/100 pounds), and high (340 tsp/100 pounds) added concentrations of the sugar or sugar-substitutes were used. These concentrations were selected according to recently published literature based on the diet of typical American teenagers. Yeast were used as a …
A Case Of Mistaken Identity In The Pathogenesis Of Type 1 Diabetes, Lynette Miller
A Case Of Mistaken Identity In The Pathogenesis Of Type 1 Diabetes, Lynette Miller
Undergraduate Student Symposium
This paper will review what happens physiologically when the body’s immune system mistakenly attacks the insulin-producing beta cells of the pancreas, resulting in the onset of Type 1 Diabetes Mellitus. The immune system is designed to fight infection and viruses, but in the case of diabetes, it responds inappropriately by targeting normal body cells and tissues. The hormone insulin is produced by specialized islet cells in the pancreas and is essential for glucose metabolism. When the body does not produce insulin, it cannot control blood glucose levels and therefore, patients must rely on subcutaneous insulin injections or continuous infusion with …

Assessing The Importance Of The Chelator Edta On Binding Of An Angiotensin Ii Analog To Neurolysin In Rat Testis And Brain Tissue Utilizing 3-Dimensional Modeling And Radioligand Binding, Andrea L. Lopez, Kira L. Santos, Yaneve Shemesh, Jamala D. Swindle
Undergraduate Student Symposium
Angiotensin II (Ang II) acts in the brain to increase blood pressure and is a major cause of cardiovascular disease and stroke. A novel non-AT1, non-AT2 binding site for ANG II in the brain was recently identified as a membrance bound-variant of the zinc metallopeptidase neurolysin. In the presence of PCMB (P-chloromercuribenzoate) and EDTA (Ethylenediaminetetracetate) 125I-sar1,ile8 Ang II binds with high affinity to neurolysin in rodent brain. To further explore the interaction of angiotensins with neurolysin we evaluated the 3-dimensional crystal structure of neurolysin. In addition we determined the importance of the zinc …
Biomechanical Justification For Training Rowers With The Power Clean, Jada Buckner, Anamaria Cretu, Kyle Gyarfas
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 …
Characterization Of The Uv Absroption Spectra Of N-Methylpyrydil Porphyrins, Kevin Winters
Characterization Of The Uv Absroption Spectra Of N-Methylpyrydil Porphyrins, Kevin Winters
Undergraduate Student Symposium
Protonation of phenyl porphyrins induced by THF has been investigated. After ionization, the positive charge was localized in the π-electron system. UV spectras have been studied for the ortho, meso, and para cation positions. Upond acid treatment of N-methyl-2-pyridyl, and N-methyl-3-pyridyl, the soret peak and Q bands showed a shlight red shift, signifying a lowering of energy levels of the excited and unexcited states of the π-electrons. However, the soret peak and Q bands of N-methyl-3-pyridyl showed a slight blue shift. This accounted for the increased solvation of π-electrons at the meso position, which increased the energy level difference between …

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

We also had the chance to observe several different specialties in surgery including cardiothoracic, neurology, obstetrics, pulmonary, pediatrics, reconstructive, and orthopedics. During our entire stay, we were on-call and responded to emergencies, which included traveling to a nearby city to collect organs for transplantation. …
The Epistemological Status Of Theoretical Simplicity, Yineth Sanchez
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. …
