Evaluation Of Mammalian Stress And Inflammatory Response To A Novel Porphyrin
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 …
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 …
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
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
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 …

Identification Of English Learners As Gifted Students
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. …

In the summer of 2015, I participated in an internship in the Wild Encounters department at the Cincinnati Zoo & Botanical Gardens. The internship required an extensive amount of training in proper animal handling, husbandry, and interpretation. This training allowed me the opportunity to work with a wide diversity of wildlife including several endangered species. The internship gave me access to a wide range of biodiversity including invertebrates such as the Madagascar Hissing Cockroach, and smaller vertebrates, such as Sand Boas and Spiny Tailed Lizards. In addition, I spent time interacting and educating the public on larger species of wildlife, …
Size, Value And Momentum In Stock Returns: An Empirical Analysis, 2010-2014
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 …

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 …

Electrical Characterization Of Tungsten Oxide Based Memristor For Improved Resistive Switching
Stander Symposium Projects
Memristor,the forth fundamental circuit element, has opened new phase in the realm of thin film semiconducting device. The non-volatility of memristors, used as Resistive switching RAM, is promising for applications such as DRAM, hard disks etc. The implementation of a memristor device with Tungsten Oxide (WOx) is presented in this work. The presentation addresses fundamental electrical characterization of the memristor devices for their switching performance. Resistive switching in WOx is bipolar in nature. The Pd/WOx/W made memristors become more conductive (resistive) when applied with a positive (negative) bias voltage. The conductance or resistance change is controlled by the re-distribution of …
Design And Prototyping Of A Variable Geometry Extrusion Die To Exhibit Significant Alteration In Shape
Stander Symposium Projects
Extruded parts are conventionally made by forcing melted plastic through a steel die having a fixed opening that matches the shape of the part. Plastic parts made by extrusion include weather stripping, PVC pipe, and composite lumber. Variable geometry dies can change their opening shape during the extrusion process. Developing shape-changing dies technology offers the possibility of making parts with varying cross-sections that currently need to be made through injection molding. This is desirable as, compared to molding, extrusion tends to be faster and less expensive. Variable geometry extrusion dies have been designed and prototyped by the University of Dayton …
Producer Prices, Cost-Push-Inflation And Stock Market Returns
Producer Prices, Cost-Push-Inflation And Stock Market Returns
Stander Symposium Projects
Although the Fed looks at the Consumer Price Index (CPI) and the Personal Consumption Expenditure index (PCE) as the key measures of inflation, in this study I focus my attention on Producer Prices (PPI) as a leading indicator of inflation in final goods produced. I want to test three hypotheses. First there is a high pass through rate for prices in the 4 basic stages of production identified by the Bureau of Labor Statistics (BLS). Using regression analysis to measure the pass through rate, I expect the b coefficients to be greater than zero and close to one. This would …
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 …

Spatial Mechanism Analysis And Synthesis By Dual Special Unitary Matrices
Stander Symposium Projects
Numerical algebraic geometry is the field that studies the computation and manipulation of the solution sets of systems of polynomial equations. The goal of this work is to formulate spatial mechanism analysis and design problems via a method suited to employ the tools of numerical algebraic geometry. Specifically, equations are developed using dual special unitary matrices that naturally use complex numbers to express physical and joint parameters in a mechanical system. Unknown parameters expressed as complex numbers readily admit solution by the methods of numerical algebraic geometry. This work illustrates their use by analyzing the spatial RCCC and RRRCC linkages. …
Star Decompositions Of The Complete Split Graph
Star Decompositions Of The Complete Split Graph
Stander Symposium Projects
A graph is a discrete mathematical structure that consists of a set of vertices and a set of edges between pairs of vertices. A problem of interest in graph theory is that of graph decomposition, partitioning the set of edges into disjoint sets, producing subgraphs which are isomorphic to each other. Here we consider the problem of decomposing a class of graphs called complete split graphs into stars of a fixed size. We present conditions for the decomposition as well as an algorithm for the decomposition when it is possible.
Can Airplane Recycling Take Off?
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
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
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 …
Wage Costs And Inflation Trends: An Empirical Analysis 2001-2015
Wage Costs And Inflation Trends: An Empirical Analysis 2001-2015
Stander Symposium Projects
Rising wage costs have often been used as a leading indication of inflation in national economies. In the US since the 2008 recession wage costs growth has, to say the least, been erratic with no discernible upward trend. In 2015, however, wage cost growth showed some signs of picking up steam suggesting that overall spending in the economy will likely pick up. In this study we examine trends in the employee cost index (ECI) from 2001 to 2015, the long term trend period, and 2009 to 2015, an intermediate term period after the 2008 recession. Linear trend equations are developed …

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
A Portfolio Weighting Strategy For A Portfolio Of 9 Large Cap Healthcare Stocks: The Case For Capture Ratios, 2010 - 2015
Stander Symposium Projects
The Capital Asset Pricing Model (CAPM) indicates that individual stocks are systematically influenced by overall price movements in the market. One way of measuring these systematic movements is through capture ratios. In this study I utilize upside/downside capture ratios to develop portfolio weights for 9 large cap Health Care stocks which make up the largest overall weight in the Health Care Sector XLV. I test the following hypotheses: (1) The upside/downside capture ratio weighted portfolio outperforms the market (S&P 500), (2) the upside/downside capture ratio weighted portfolio outperforms XLV. (3) The performance of the upside/downside capture ratio weighted healthcare portfolio …

Avoiding The Guillotine: The Need For Balance And Purpose In Determining Fundamental Rights Under The Fourteenth Amendment
Stander Symposium Projects
This paper argues the need for a balanced approach between traditionalism (including history) and rationalism to determine fundamental rights under the Fourteenth Amendment of the U.S. Constitution. The issue of how to determine fundamental rights has intrigued the Supreme Court of the United States since 1798. The Supreme Court has desired an “objective” approach to determine what rights are “fundamental.” However, the Supreme Court has had difficulty finding an objective approach. This is because, as E.O. Wilson and Joshua Greene observed, rights are naturally subjective creations of an individual’s values. Thus, any test to determine fundamental rights will be subjective …
