Re (Cell) Lcd: A Feasibility Study On Recycling Cell Phone Lcd Apr 2016

Re (Cell) Lcd: A Feasibility Study On Recycling Cell Phone Lcd

Stander Symposium Projects

Liquid Crystal Displays (LCD) are used in a magnitude of devices and have now become the norm in products that require a screen, such as, cell phones, computers, televisions, tablets, and more. However, many of these technologies are becoming outdated leading towards the issue of exponential growth of waste with a lack of technology set in place for proper recycling. Most of research literatures on LCD recycling are of electronic products and e-waste in general rather than cell phones in particular. Few studies on recycling of cell phone LCD have been accomplished. Since everyday around 300,000 mobile phones are sent …


Identification Of Potential Acrab-Tolc Efflux Pump Inhibitors In Escherichia Coli Using An Ethidium Bromide Method. Apr 2016

Identification Of Potential Acrab-Tolc Efflux Pump Inhibitors In Escherichia Coli Using An Ethidium Bromide Method.

Stander Symposium Projects

Many bacteria are known to exhibit antibiotic resistance through overexpression of efflux pumps. In this experiment, inhibition of a bacterial efflux pump through the physical binding of small molecule inhibitor compounds was explored as a way to combat substrate expulsion. The TolC protomer of the AcrAB-TolC efflux pump in Escherichia coli was targeted in a virtual screen for novel small molecule inhibitor compounds. PyRx AutoDock Vina was used to virtually dock the various small molecules to the TolC protein and rank the compounds based on favorable binding energies. Five lead-compounds from the virtual screen were ultimately selected for in vivo …

Identification Of English Learners As Gifted Students

Stander Symposium Projects

The United States educational system has faced several challenges and reforms regarding assessment and identification in the past fifty years which continue to change as the nation develops new goals and needs (Giuliani & Pierangelo 2012). In recent years, schools have included a large population of immigrant students from families with native languages other than English (Carter 2005). The need for educating students in English as a second language has led to new policies and programs developed specifically for ELL or English Language Learners (Elizalde-Utnick 2008). Another current topic of educational policy concerns the emphasis on assessment and high-stakes testing. …

Capture Ratio Analysis And The Materials Sector Xlb: A Performance Review For 2010-2015

Stander Symposium Projects

The materials sector performance has had a challenging time over the last few years. A slow down in China and Europe certainly have been contributing factors in XLB's weak performance. In this study, I evaluate a portfolio weighting model based on capture ratios. The covariance in price peformance between large-cap stocks in the materials sector and the market (S&P 500). In this study I use a concentrated portfolio of the 10 biggest cap-weighted stocks in XLB and weight their position in the portfolio by upside/downside capture ratios. I then test the following hypotheses; 1.)The 10 materials stocks portfolio weighted by …


Finding Physicians Fast: Making Finding A Doctor Easier For Esl Students Apr 2016

Finding Physicians Fast: Making Finding A Doctor Easier For Esl Students

Stander Symposium Projects

In the realm of healthcare, it is often difficult to decipher how to locate personal and primary physicians. Those living in the United States are familiar with the role of family care physicians, however, individuals who have immigrated to the U.S. may not fully understand how to find a family physician. The topic of family physicians is important because many other countries do not have primary care physicians that require appointments. For our project, we took two documents that tested at a reading level of 12th grade. We did this by testing the original documents with the SMOG test and …

Portfolio Weighting Strategies For A Concentrated Portfolio Of Consumer Discretionary Stocks: An Empirical Analysis, 2010-2015

Stander Symposium Projects

Recent interest by investment managers in Portfolio Weighting Strategies other than market capitalization has led to a rapid increase in fundamental based indexing. In their study I use the price dynamics of firms relative to the market (S&P 500) to weight a 10 stock portfolio of Consumer Discretionary firms. The weighting model is based on the capture ratio of the price changes for each stock compared to the S&P 500. In particular, an upside/downside capture ratio is developed for each stock based on a years worth of daily price changes. The following hypotheses are tested: 1) Firms with higher upside/downside …


Examining Factors Associated With High Leadership Self-Efficacy Among International Women College Students In The U.S. Apr 2016

Examining Factors Associated With High Leadership Self-Efficacy Among International Women College Students In The U.S.

Stander Symposium Projects

Leadership self-efficacy is an area of self-efficacy related to the level of confidence one has in his or her knowledge, skills, and abilities to lead others (Bandura, 1997). When leadership self- efficacy is placed within the context of student development, it has the ability to contribute to or negate from a student’s motivation to persist and succeed in leadership associated tasks (Bandura, 1993; Stage, 1996). The goal of this research is to explore how international female undergraduate students perceive their leadership abilities in relation to their personally constructed definition of leadership. Through qualitative interviews with six international female undergraduate students, …

Do High Roe Stocks Outperform The Market With Persistence: An Empirical Analysis, 2009 - 2014

Stander Symposium Projects

Academic studies by Eugene Fama and Kenneth French as well as Robert Novy Marx identify profitability as one of the factors determining the variation in excess returns in the cross section of stock returns. Using return on equity (ROE) as my measure of profitability and the S&P 500 as my universe of stocks, I examine the impact of ROE on S&P 500 stock performance for the period 2009 - 2014. I test the following hypotheses with respect to ROE: (1) Portfolios of firms with high ROE's (40% or higher) outperform the market with persistence i.e. over long periods of time, …


Dissecting The Sex-Dependent Neurochemical Effects Of The Rapid-Acting Antidepressant Drug Ketamine With In Vivo Brain Microdialysis In Mice Apr 2016

Dissecting The Sex-Dependent Neurochemical Effects Of The Rapid-Acting Antidepressant Drug Ketamine With In Vivo Brain Microdialysis In Mice

Stander Symposium Projects

Major depression is a devastating mental disorder that affects nearly 20% of the world’s population. Notably, women experience major depression at roughly twice the rate of men and respond differently to different types of antidepressant drugs. However, the neurobiological mechanisms underlying this sex-differentiated responsiveness remain a largely neglected area of experimentation with current treatments based almost exclusively on research conducted in males. Most importantly, currently marketed antidepressant drugs take anywhere from weeks to months in order to elicit their therapeutic effects, thus leading to increased drop-out rates. Ketamine is a unique, rapid-acting antidepressant drug that alleviates depressive symptomatology in both …


Supplementation Of Propionate Inhibits The Anaerobic Growth Of The Foodborne Pathogen Listeria Monocytogenes Apr 2016

Supplementation Of Propionate Inhibits The Anaerobic Growth Of The Foodborne Pathogen Listeria Monocytogenes

Stander Symposium Projects

Listeria monocytogenes is an infectious bacterium that is known to cause severe diseases in people who are pregnant, elderly, or generally immunocompromised through consumption of contaminated food products. To help develop preventative strategies to protect these high-risk individuals, our lab focuses on the approach of enhancing the chemical barrier naturally existing in the intestinal tract to block L. monocytogenes from interacting with the human intestinal epithelium and causing fatal infections. The chemical environment inside the human intestinal lumen is rich with fermentation acids produced by the endogenous microbes. In my research project, I tested the efficacy of propionic acid, one …


The Use Of A Molecular Probe To Investigate The Details Of Pria Helicase Function Apr 2016

The Use Of A Molecular Probe To Investigate The Details Of Pria Helicase Function

Stander Symposium Projects

During DNA replication in both eukaryotic and prokaryotic cells, the replication machinery (replisome) invariably encounters structural DNA damage, an event that can result in disbanding of the replisome and the creation of a collapsed replication fork. In order for DNA replication to continue, the replisome must be reloaded onto the DNA strand, a process that often begins with unwinding of double-stranded (duplex) DNA by the primosome protein PriA. Little is known about the mechanism through which PriA unwinds DNA and begins replisome recruitment. We seek to shed new light on this mechanism through the use of a PriA inhibitor, compound …


Role Of Axial Patterning Genes In Growth Regulation During Eye Development Apr 2016

Role Of Axial Patterning Genes In Growth Regulation During Eye Development

Stander Symposium Projects

An important question in developmental biology is that how axial patterning genes work with growth and patterning to form any three-dimensional organ. In any multicellular organism, Organogenesis, requires axial patterning i.e. formation of Antero-Posterior (AP), Dorso-Ventral (DV), Proximo-Distal (PD) axes. Any deviation in these axes during development leads to genetic birth defects. We use Drosophila melanogaster (a.k.a fruit fly), eye as our model. As the genetic machinery between flies and human is conserved, any insights generated in flies can be extrapolated into humans. In Drosophila, DV patterning marks first lineage restriction event where expression of dorsal, ventral fate selectors forms …


Mutant Pria C-Tev Ml346 And Its Unwinding Dna Capabilities Apr 2016

Mutant Pria C-Tev Ml346 And Its Unwinding Dna Capabilities

Stander Symposium Projects

DNA damage can cause the process of DNA replication to stall and this can lead to dissociation of the DNA replication enzymes from the DNA. In bacteria, a protein called PriA recognizes this, unwinds a portion of duplex DNA at the site where replication stalled, and reloads the replication enzymes to restart DNA replication. PriA has multiple structural domains that are closely associated with one another to give rise to a compact globular protein. The winged helix domain, however, is connected to the remainder of the protein by a long, flexible portion of polypeptide, akin to a tether. I examined …


A Numerical Solution Of A Model Of Diabetes Apr 2016

A Numerical Solution Of A Model Of Diabetes

Stander Symposium Projects

Many researchers use mathematical models to understand and predict the behavior of biological systems. In this work we consider a mathematical model for diabetes mellitus presented by Hussain and Zadeng to study a metabolic disease for the regulation of glucose in the body by pancreatic insulin. The mathematical models consists of two ordinary differential equations for glucose concentration and insulin concentration. In particular, this study attempts to numerically solve the model using the Runge-Kutta methods of order 2 and 4. We will also perform a qualitative analysis on the behavior of the system


Culture As Context: Effects Of Cultural Polarization On Chinese International Student Adjustment Apr 2016

Culture As Context: Effects Of Cultural Polarization On Chinese International Student Adjustment

Stander Symposium Projects

Due to the fact that Chinese international students are such a significant population within American universities across the country, it is worth investigating how this population typically adjusts to living in the United States and what stresses or issues are unique to them. However, it is also important to investigate whether or not Chinese international students experience positive transformations within themselves as a result of the adjustment challenges that they are faced with. This qualitative inquiry examines these vital questions surrounding Chinese international student adjustment, in order to contribute to a more holistic understanding of the complex experiences of Chinese …


State Initiatives, Ballot Language, And The Media: Do They Overlap? Apr 2016

State Initiatives, Ballot Language, And The Media: Do They Overlap?

Stander Symposium Projects

State Initiatives are seen throughout every state, some more than others, but every election brings them. However, not every election is equal when it comes to turnout, depending on if it is a presidential or midterm year. Some are given more media attention, some are given minimal attention, if at all. The fundamental question is what role doe’s media play in turnout during elections and does any amount of roll-off occurs during presidential or governor’s elections? Does this poll-off or turnout have to do with media (or lack of) attention, or is there something more going on? Besides looking at …


Honor's Thesis Proposal: Effects Of Tactile Versus Electronic Games On Attention, Distraction, And Understanding Apr 2016

Honor's Thesis Proposal: Effects Of Tactile Versus Electronic Games On Attention, Distraction, And Understanding

Stander Symposium Projects

The ability to attend to relevant information and resist attention to distractors is important for children’s cognitive development. Difficulties with attention can impede memory development and impact learning. Much has been written in the news about the impact of electronic media on children’s development of attention skills, but little research has been done explicitly comparing children’s attention to relevant information and resistance to distractions across activities that are presented in either tactile or electronic format. The goal of this study is to compare levels of attention and distraction among preschool-aged children while they engage in a common childhood activity, playing …


Investigation Of The Role Of Mitochondrial Dysfunction As A Trigger For Neurodegeneration In Alzheimer’S Disease Apr 2016

Investigation Of The Role Of Mitochondrial Dysfunction As A Trigger For Neurodegeneration In Alzheimer’S Disease

Stander Symposium Projects

Alzheimer’s disease is a progressive neurodegenerative disorder that affects cognitive function and memory of the patient. It results from plaques formed by the abnormal cleavage of the Amyloid Precursor Protein (APP), which result in the formation of 42 amino acid polypeptide, also known as amyloid beta 42 (Aβ42). Accumulation of Aβ42 peptide triggers cell death in the neuronal cell population of central nervous system. However, the trigger for this abnormal cell death is unknown. I will investigate the role of mitochondrial dysfunction as the trigger for neurodegeneration. Since the mitochondria is the site for triggering neurodegeneration, its malfunction or loss …


Can Airplane Recycling Take Off? Apr 2016

Can Airplane Recycling Take Off?

Stander Symposium Projects

As of 2015, the worldwide air transportation industry is expected to contain an estimated 10,000 aircraft ready for retirement. In order to offset the introduction of waste from aircraft disposal into landfills, as well as to cope with the depletion of natural resources, the recycling of airplanes is becoming more prevalent. Aircraft Recycling is a process of highly variable economic revenues. Often, the difference between having a loss and a profit is with the resale of aircraft parts, namely the engines. Recycling companies often have to charge the owner of an aircraft for the recycling process in order to make …


Research Exercise: Amplifying Signals Via Riboswitch Biosensors Apr 2016

Research Exercise: Amplifying Signals Via Riboswitch Biosensors

Stander Symposium Projects

The Air Force is always in search of new and efficient ways to protect the lives of their Airman and equipment. Biosensors are self-sufficient, natural systems that can report a signal based on the presence of a specific molecule. However, biosensors are limited by a low signal output. Here we describe how a biological amplification circuit, loosely based on concepts similar to electrical circuitry, will be used to produce and amplify a signal. The biosensor consists of sensing cells and reporter cells that are ‘wired’ together via quorum-sensing signal molecules. The sensing cells contain a riboswitch that activates the reporter …


Robust Nonlinear Adaptive Control For Longitudinal Dynamics Of Hypersonic Aircraft Vehicle Model Apr 2016

Robust Nonlinear Adaptive Control For Longitudinal Dynamics Of Hypersonic Aircraft Vehicle Model

Stander Symposium Projects

A hypersonic aircraft vehicle is a highly complex nonlinear system, which includes uncertainties in the dynamics. This paper presents the design of robust nonlinear adaptive control for a hypersonic aircraft vehicle model. The complexity of the dynamic system is considered into the design structure of the control in order to address robustness issues. Design of a robust control system should decouple the longitudinal and lateral dynamics to handle the flight of hypersonic vehicle under certain specific conditions. In this paper, we only consider longitudinal dynamics, which are divided into aircraft speed subsystem and flight-path angle subsystem. A robust control design …

Monetary Policy And Unemployment Rates: Is There A Relationship? An Empirical Analysis: 2001-2015

Stander Symposium Projects

The Federal Reserve has a dual mandate to carry out Policy objectives that bring about full employment in the economy with price stability. On the full employment side, monthly job growth along with unemployment rates are two key metrics that indicate how well the fed is doing in achieving the mandate. In this study, I focus on unemployment rate trends over the period 2001-2015.In 2001, the U.S. economy was dealing with a mild recession and in 2008 a severe recession. I look at the trend in the unemployment rate for the periods 2001-2007 and 2009-2015 to obtain a better understanding …


Evaluation Of Mammalian Stress And Inflammatory Response To A Novel Porphyrin Apr 2016

Evaluation Of Mammalian Stress And Inflammatory Response To A Novel Porphyrin

Stander Symposium Projects

Porphyrins are a specific class of aromatic, heterocyclic compounds that are either naturally occurring or artificially synthesized. Porphyrins have demonstrated robust antibacterial properties, which arise from the generation of singlet oxygen. However, most porphyrins are photodynamic, meaning they require activation by light at an optimal wavelength. A novel porphyrin, developed by Dr. Shawn Swavey (UD Chemistry Department) has shown exceptional antibacterial efficiency against Pseudomonas aeruginosa, even without photoactivation. As P. aeruginosa infections are often the root cause behind lung diseases, such as cystic fibrosis, identifying a way to safely control bacterial presence is a major concern. The ability of this …


Greek Life And Catholic Universities: Do The Values Of Greek Life Match With Those Of The Catholic Church? Apr 2016

Greek Life And Catholic Universities: Do The Values Of Greek Life Match With Those Of The Catholic Church?

Stander Symposium Projects

Greek Life organizations face many negative stipulations across the United States due to several allegations of disrespectful actions. Due to these negative actions, there are Catholic institutions across the United States that do not allow Greek Life organizations on their respective campus. Such reasons Catholic institutions give is that Greek Life is not needed on campus for students to live out Catholic values. Instead, students have service, special interest and sports clubs to join to live out Catholic values. As a student apart of Greek Life on the University of Dayton’s campus feel that the values between Greek life and …


Effects Of Body Weight Loading On Arch Height Apr 2016

Effects Of Body Weight Loading On Arch Height

Stander Symposium Projects

Foot functionality is integral to normal human locomotion. The most commonly assessed area of the human body studied during locomotion is the medial longitudinal arch and its deformation. The Arch Height Index Measurement System (AHIMS) is the most reliable tool to measure this arch. This system typically measures arch deformation in two baseline conditions, sitting and standing. The sitting condition is considered unweighted and approximately 10% of a person’s body weight. The standing condition is considered a loaded condition and represents 50% of body weight. The first aim of this study was to see if the baseline measurements traditionally taken …


Portfolio Weights And Capture Ratio Analysis: A Look At Performance In The Consumers Staples Sector 2010-2015 Apr 2016

Portfolio Weights And Capture Ratio Analysis: A Look At Performance In The Consumers Staples Sector 2010-2015

Stander Symposium Projects

Since the recession in 2008, the stock market has experienced periods of extreme volatility, with market moves of 200-400 points on almost a daily basis. One sector that should do well when market volatility is high and rising is consumer staples. In this study I use a dynamic pricing model to determine the portfolio weights for the 10 largest value weighted stocks in the consumer staples sector. The model relies on the upside/downside Capture Ratios (U/D) for each stock to calculate the portfolio weights and dollar investment in each stock. I test the following hypotheses: (1) Stocks with higher U/D …


Size, Value And Momentum In Stock Returns: An Empirical Analysis, 2010-2014 Apr 2016

Size, Value And Momentum In Stock Returns: An Empirical Analysis, 2010-2014

Stander Symposium Projects

Based on the landmark studies of Eugene Fama and Kenneth French in the 1990's, most financial economists consider a firm's market capitalization (size) and price to book as two of the most important factors affecting the cross section of stock market returns. In recent years, other factors including stock price momentum have been accepted as predictors of stock returns in the cross section. In this study, I develop a three factor analysis of S&P 500 stock returns for the period 2010-2014. This period was chosen because it is not included in more recent studies. It also reflects a period of …
