Bmi Associations Between Mother And Offspring From Birth To Age 18: The Fels Longitudinal Study
Bmi Associations Between Mother And Offspring From Birth To Age 18: The Fels Longitudinal Study
Stander Symposium Projects
Introduction: It is reported that two of three American adults are classified as overweight or obese; and one in three of their offspring will become overweight or obese (Sun et al., 2012). Because parental obesity is a risk factor for childhood obesity, children can also be pre-exposed to risk factors for chronic diseases such as diabetes, hypertension, coronary artery and cardiovascular diseases. It has been well established that body composition is affected by many variables such as age, sex, race, in addition to the familial environment affects such as diet and exercise habits (Baumgartner et al., 1994). Previous research has …
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 …

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 …
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 …
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 …
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 …
Social Support Influences In Graduate International Student Engagement
Social Support Influences In Graduate International Student Engagement
Stander Symposium Projects
Changes that graduate international students face in acculturating to U.S. educational environments can often impact the ways they engage on campus, and their subsequent personal and career success. This poses the question of “What are the key themes that institutions can build upon to better support and encourage their growth?” In conducting a mixed-methods study on the lived experiences of graduate students from India, main findings suggested that mentoring relationships, social ties, and factors of perception were crucial to influencing students’ academic and social engagement.
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 …
Design And Fabrication Of Fourier Spectral Filter Array For Multispectral Imaging
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, …

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 …
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 to indirectly increase the physical …

Older adults with dementia are at an increased risk for falls. However, little is known about what specific factors increase fall risk in this population. The purpose of this study was to assess performance based fall risk factors among older adults with dementia who attend day service programs in the Miami Valley so that more specific interventions can be designed to reduce future falls. To be included in this study, participants had to attend Goodwill Easter Seals Adult Day Service and have a diagnosis of dementia. There were 19 participants in this study (8 male) with an average age 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 …
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 …
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
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 …

Internship Experience Through The Wild Encounters Program Of The Cincinnati Zoo
Stander Symposium Projects
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, …
The Implementation Of Two-Way Immersion Programs
The Implementation Of Two-Way Immersion Programs
Stander Symposium Projects
As society becomes more global, educators are searching for models of education that provide students with the ability to be competitive in the global marketplace. Bilingual education offers students the opportunity to learn two languages while maintaining student achievement in other content areas. One option of bilingual education is called two-way immersion (TWI) programs. TWI classrooms are comprised of students who are native speakers of two different languages. Together, these students communicate in both languages, while receiving instruction in both languages as well. These programs have been shown to be effective in teaching two languages without lowering student achievement. Bilingual …
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 …
Inflation Trends In Personal Consumption Expenditures, 2001-2015
Inflation Trends In Personal Consumption Expenditures, 2001-2015
Stander Symposium Projects
The Federal Reserve, as a key element in its monetary policy, uses a 2% target inflation rate to determine if the federal funds rate needs to be increased. The purpose of this study is to evaluate long, intermediate, and short term trends in inflation to determine if the inflation policy objective has been reached. My inflation metric is Personal Consumption Expenditure (PCE) and the period of analysis is 2001-20015. I develop linear trend equations for both PCE and PCE less food and energy using the b coefficients from the regressions as a proxy for the PCE inflation rate. Out of …

This study examines the cross-cultural engagement between international and domestic undergraduate engineering students at a private, Midwestern university. 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 …
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 …

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