Intellectual Property And The Ncaa
Intellectual Property And The Ncaa
Stander Symposium Projects
The research aim of this project is to examine the legal issues regarding intellectual property with student athletes who participate in sports under governance of the NCAA. Intellectual property rights are for creative works which are designated to specific people or businesses by law. This research thesis will examine the conflict the NCAA has with student athletes that argue they should be obtaining revenue from autographs, jersey sales, etc. The Ed O’Bannon case, which just concluded and is now in the settlement phase, will be a major focal point of this research project. Ed O’Bannon sued the NCAA for using …
Electrical Characterization Of Tungsten Oxide Based Memristor For Improved Resistive Switching
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 …
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.
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
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
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
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
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
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
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
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
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?
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
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
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?
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
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
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?
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 …
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 …
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 …
Spatial Mechanism Analysis And Synthesis By Dual Special Unitary Matrices
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.

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 …
