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
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 …

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.
Developing Trend Equations For Cpi:As Empirical Analysis 2001-2015
Developing Trend Equations For Cpi:As Empirical Analysis 2001-2015
Stander Symposium Projects
Since the 2008 recession, overall inflation as measured by CPI has been perceived to be almost non existent. In recent months, however, inflation is picking up, which in a perverse sort of way is seen as good for the economy. The purpose of this study, therefore, is to more clearly understand CPI trend inflation. To that end, I looked at a long term trend, 2001-2014, two intermediate term trends, 2001-2007 and 2009-2014 and a short term trend, 2013-2014. Monthly and yearly linear trend equations were developed for the long and intermediate term time periods. For the shorter time period 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, …

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 …

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 …
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 …

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, …
