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 ...


Design And Prototyping Of A Variable Geometry Extrusion Die To Exhibit Significant Alteration In Shape Apr 2016

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 ...


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 ...


Effect Of Combination Ice And Compression Socks On Resting Calf Blood Flow In Trained Male Athletes Apr 2016

Effect Of Combination Ice And Compression Socks On Resting Calf Blood Flow In Trained Male Athletes

Stander Symposium Projects

Compression socks are common tools that are utilized in the realm of athletics. The purpose of the compression is to increase blood flow to the lower extremities, thereby increasing oxygen and energy sources needed for increased skeletal muscle function and/or recovery. Recently, a product has been marketed that combines the compression element and cryotherapy, with the goal being increased blood flow to the lower extremities while reducing inflammation post-workout to quicken recovery. However, to our knowledge, direct measures of blood flow using this type of product have not been performed. Thus, this study looks at the effects of compression ...


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 ...


Capture Ratio Analysis And The Materials Sector Xlb: A Performance Review For 2010-2015 Apr 2016

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 upside/downside capture ratios outperforms the market (S&P 500) 2.) The upside/downside capture ratio weighted concentrated portfolio of materials stocks outperforms XLB and 3.) The concentrated portfolio of materials stocks ...


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 ...


Intellectual Property And The Ncaa Apr 2016

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 ...


Spatial Mechanism Analysis And Synthesis By Dual Special Unitary Matrices Apr 2016

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 ...


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 ...


Design And Fabrication Of Fourier Spectral Filter Array For Multispectral Imaging Apr 2016

Design And Fabrication Of Fourier Spectral Filter Array For Multispectral Imaging

Stander Symposium Projects

Multispectral imaging has the capability to identify the state of objects based on their spectral characteristics. These are features not available with conventional color imaging based on metameric RGB (red, green and blue) colors alone. Current multispectral imaging systems use narrowband filters to capture the spectral content of a scene, which necessitates different filters to be designed and applied for each application. We have demonstrated the concept of Fourier multispectral imaging which uses filters with sinusoidally varying transmittance by time multiplexed switchable filter array in our previous paper [1, 2]. In this paper, we designed and built a five channel ...


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 ...


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 ...


Avoiding The Guillotine: The Need For Balance And Purpose In Determining Fundamental Rights Under The Fourteenth Amendment Apr 2016

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 ...


Identification Of English Learners As Gifted Students Apr 2016

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 2004, the Individuals with Disabilities Education Act, IDEA, provided legal rights and expectations for special education students which includes students with learning disabilities; however, English Language Learners are not covered under IDEA unless they are identified with a learning disability. IDEA also does not cover the rights of students who qualify for gifted and talented programs, even though students who qualify for these programs require a form of specialized education. Due to these recent educational initiatives, this research study will focus on how the assessment of English Language Learners impacts ...


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 ...


Star Decompositions Of The Complete Split Graph Apr 2016

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.

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 ...


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 ...

It uncovers the situations in which international and domestic students are engaging and explores the components which help or hinder the cross-cultural interaction between these students. This study informs higher education professionals endeavoring to provide undergraduate engineering students a greater ability to function in a global world. Data was collected through the use of one-on-one interviews with current international and domestic undergraduate engineering students. The study revealed that while international and domestic engineering students are engaging, the frequency remains low and there ...


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 ...


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 ...


Can The Color Red Improve Men’S Perceived Mate Value?: Examining The Interactive Effects Of Facial Masculinity And Color On Female Evaluation Of Potential Mates Apr 2016

Can The Color Red Improve Men’S Perceived Mate Value?: Examining The Interactive Effects Of Facial Masculinity And Color On Female Evaluation Of Potential Mates

Stander Symposium Projects

We manipulated facial masculinity (masculine-morph/feminine-morph) and color (red/white) through two independent studies—one in-lab at the University of Dayton and one online using Amazon’s MTurk—to examine its effect on social status and attractiveness for men when rated by women. We specifically aimed to see if the color red could serve a compensatory effect for feminine-faced men, who were least likely to be found attractive by women at peak fertility. When paired with red, women rated the masculine and feminine faces higher in social status. Through this increase in social status, the color red was also able ...


Research Exercise: The Development Of A First Year Chemistry Laboratory Apr 2016

Research Exercise: The Development Of A First Year Chemistry Laboratory

Stander Symposium Projects

The purpose for this project was to redesign a past General Chemistry Laboratory experiment with emphasis on student learning objectives in support of lecture material. The experiment was first introduced into the second semester CHM124L course in 1997 as “Preparation and Investigation of Salt Solutions”. For the Fall 2016 curriculum, the modified experiment will be conducted in the first semester General Chemistry course CHM123L as “Equilibrium of Salt Solutions”. This experiment was chosen for modification because the concept of equilibrium, especially when applied to pH of salt solutions, is one that many students find difficult to understand. Experiencing the concept ...


Portfolio Weighting Strategies For A Concentrated Portfolio Of Consumer Discretionary Stocks: An Empirical Analysis, 2010-2015 Apr 2016

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 ...


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


Creating Value Through Sustainable Manufacturing Apr 2016

Creating Value Through Sustainable Manufacturing

Stander Symposium Projects

To support movement toward a more sustainable worldview, increasing manufacturing efficiency or productivity to improve business profitability and return to shareholders alone is no longer sufficient. Today, leading manufacturers employ business practices that generate sustainable value—that is, creating economic, environmental, and societal value for all stakeholders. Progressive company culture, environmental and energy management systems, carbon neutrality, and becoming landfill free are all valuable outcomes of sustainable manufacturing. This poster outlines the the value of these outcomes as well as methods to achieve sustainable manufacturing.

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 ...

Wage Costs And Inflation Trends: An Empirical Analysis 2001-2015 Apr 2016

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 ...
