An Empirical Study Of The Relationship Between Stock Market Price Movements And Macro Financial Conditions, 2001-2013
Stander Symposium Projects
Since the early 90's, a number of financial condition indexes have been developed to determine future movementsin the non-financial sectors of the economy. In this study, I use the Kansas City Federal Reserve's index of financial Stress (KCFSI) to study the relationship between market and sector price movements and macro financial conditions. The periods of analysis are :(1)2001-2012), (2) 2003-2007,(3) 2009-2012). The long run period includes two recessions and two sustained periods of economic growth. The two short run periods represent economic rebound periods after the recessions. Using uni-variate regression models regress KCFSI on Spy, the S&P 500 ETF, as …
All The Single Ladies: Romantic Partnering And Its Influence On The Self-Esteem Of Female College Students
Stander Symposium Projects
As college students understand and vocalize their needs, supports, and decisions, they begin to believe in their own choices and build confidence and self-esteem. Early on in their undergraduate years, many female students define themselves by their social relationships and cannot separate themselves from whom they are associated with. Thus, those in a committed romantic relationship may have more validation and support for fostering self-esteem than those who are not romantically involved. The current study seeks to understand the relationship between 250undergraduate female students’ levels of self-esteem and romantic partnerships, and projected changes if the relationship status were to change. …
Community Despite Contingency: Working Together, Achieving Together
Community Despite Contingency: Working Together, Achieving Together
Stander Symposium Projects
In the changing context of higher education, many faculty members are experiencing an increased workload, more accountability, fewer resources, and a changing student demographic (Eddy & Garza-Mitchell, 2012), which can result in a faculty who feels overworked and disconnected. Learning Communities have been used as a way to meet the needs of faculty members by developing a sense of community and reinvigorating their scholarship of teaching (Cox, 2004). While learning communities can work well for faculty, the largest growing subset of the professoriate, adjunct faculty, often do not have this support. Adjunct faculty are generally not satisfied with the support …

Research Exercise: Google/Multi-National Corporations, International Surveillance, And Human Rights
Stander Symposium Projects
The many news reports on cyber security, identity theft, Wikileaks, and NSA intelligence gathering programs over the past few years have shown the international community that the World Wide Web is anything but a safe place to store sensitive information, or any information for that matter. This study will examine how closely multi-national corporations in the information technology sector, such as Google, are involved with national governments on these issues. The study will analyze events in the U.S. and China and attempt to uncover whether or not these have directly infringed upon peoples’ basic human rights.

Dmso And Temperature Contributions To Synthesis Of Silver Nano-Particles By The Bacterium Shewanella Oneidensis
Stander Symposium Projects
Nanomaterial are widely used in different areas such as optical device, drug delivery, chemicals, mechanics, magnetics, catalysis, energy science, Nano therapeutics and space industries depend on the special physical properties. However, most methods to produce nanoparticles are expensive or environmental unfriendly which can involve in toxic chemical. Another reason is that the nanoparticles from bio-based protocols are hydrophilic which is compatible with biological materials. In this project, we chose Shewanella oneidensis which is Gram-negative bacterium as the organism to produce sliver nanoparticles from sliver nitrate solution. The mechanism of bacterial of ion metal ion reduction to stable metal nanoparticles is …

Embodied Cognition: A Study Of Social Loneliness Compensation By Physical Warmth
Embodied Cognition: A Study Of Social Loneliness Compensation By Physical Warmth
Stander Symposium Projects
The following study investigated embodied cognition and its effect on social loneliness compensation with physical warmth. Bargh and Shalev (2012) were able to support the notion of embodied cognition—our thoughts depend on our bodies and vice versa—suggesting that a socially lonely person will compensate for their loneliness with physical warmth, specifically warmer, more frequent and longer showers or baths. This also suggests an unconscious self-mechanism for the body and mind to self-regulate. This study also investigates embodied cognition in regard to social loneliness compensation with physical warmth, and also a further proposal that a person with higher sensitivity to their …
Research Exercise: Fund Allocation Strategies For Etfs: A Contrarian Approach
Research Exercise: Fund Allocation Strategies For Etfs: A Contrarian Approach
Stander Symposium Projects
In this study, I evaluate a portfolio weighting strategy called inverse relative price strength (IRPS). This weighting strategy gives higher weights to ETFs with lower prices relative to some benchmark price. The benchmark price is the Russell 3000 Index. IRPS is dynamic in that the weights change as relative prices change. The six ETFs evaluated in this study are large cap growth, mid cap growth, small cap growth, large cap value, mid cap value, and small cap value. As mentioned above, all of these ETFs trade on the market like individual stocks but are constructed in such a way that …

Examination Of Host Range Of Pseudomonas Aeruginosa Phages Ut1, Sn-T, And Pev@ For Treatment Of Bacterial Biofilms In Fuels
Stander Symposium Projects
Biofilms are slimy substances made up of bacteria that attach to surfaces. Biofilms can be found in natural settings (rocks in streams) and man-made environments (hospital catheters, pipelines). Biofilms are also found in aviation fuel tanks, causing physical issues such as clogging in fuel lines and changing the chemical makeup of the fuel via bacterial metabolism. Bacterial viruses, known as phage, show potential for reducing biofilms through phage therapy. The goal is to find a phage or combination of phage with a broad host range that would be most effective in reducing the biofilms of bacteria isolated from fuel tanks. …

Heat Transfer Coefficient Correlations For Pumparound Sections Of Petroleum Fractionation Towers
Stander Symposium Projects
The accuracy of several empirical correlations for estimating heat transfer coefficients within pumparound sections of atmospheric and vacuum petroleum fractionation towers was investigated. The heat transfer coefficients were estimated according to the C.F. Braun correlation for trayed pumparounds and the atmospheric and vacuum Glitsch correlations for packed pumparounds. From these correlations, heat transfer coefficients were estimated for 43 different petroleum fractionator pumparounds based on operating data gathered from nine refineries around the globe. The accuracy of the correlations was evaluated by comparing the estimated heat transfer coefficients to actual values calculated from operating data. Results showed that while the C.F. …

Its Snowing: A New Outlook On Motion-Induced Blindness
Its Snowing: A New Outlook On Motion-Induced Blindness
Stander Symposium Projects
Motion-induced blindness occurs when an unchanging part of the visual field that is stationary relative to the fovea perceptually disappears when, in fact, the stimulus is still present. It was originally thought to be related to the fact that a target stimulus is stationary while other objects in the visual field are uniformly moving, hence the name of the phenomenon. However, it has since been established that motion, per se, is not necessary for motion-induced blindness to occur and that motion-induced blindness can occur in the presence of any type of uniform change, such as a collection of lights getting …
Improving Female Science Scores Through Stem Curriculum
Improving Female Science Scores Through Stem Curriculum
Stander Symposium Projects
Currently in education there is a stress on career readiness. Specifically in science education, teachers are expected to educate their students not only on science concepts but also careers that involve Science, Technology, Engineering, and Mathematics (STEM). According to the United States Department of Education (2013), the United States is falling behind on mathematics and science education, ranking 25th and 17th in the world. These numbers must increase in order to prepare students for success in STEM fields as they graduate. One approach teachers use to ensure that students are well versed in the STEM fields is STEM education. In …
Party Building: Factors To Encourage Third Party Support Among 18-24 Year Olds
Party Building: Factors To Encourage Third Party Support Among 18-24 Year Olds
Stander Symposium Projects
Third parties have always existed within American politics, yet have never claimed the ultimate political victory: the Presidency. Third parties often enjoy support from single issue voters, a strong, concentrated group of serious devotees, but they often fail to attract more consistent backing similar to that enjoyed by the two major parties. A major source of third party patronage is also found on the university campus, yet this support often fades shortly after college. Using survey data, this thesis analyzes the potential impact party building and media campaign strategies would have on third parties in gaining the lasting support of …
Purification And Biochemical Characterization Of A Xylanolytic Glycoside Hydrolase From Caldicellulosiruptor Saccharolyticus
Stander Symposium Projects
In response to the current global energy crisis, biofuels have become a viable renewable energy solution and require a carbohydrate source to begin their production. One such carbohydrate source option is biomass, which is comprised of complex sugars that can be broken down into simple sugars and then fermented for the production of bioethanol. The bacterium called Caldicellulosiruptor saccharolyticus contains many glycoside hydrolase enzymes that have the potential for metabolizing the complex sugars in several carbohydrate sources, including those in biomass. This project is focused on the cloning of the Csac_2410 gene from C. saccharolyticus, expression of the gene as …
Statistically Equivalent Serial Chain Modeling With Kinect And Wii Balance Board
Statistically Equivalent Serial Chain Modeling With Kinect And Wii Balance Board
Stander Symposium Projects
Identifying the center of mass location provides a significant aid in controlling the balance of humanoid robots. Additionally, in humans this location is an essential parameter in postural control and is critical in assessing rehabilitation. Anthropometric tables have been complied for this identification but their accuracy is readily questioned. This research presents an estimation technique that uses the statically equivalent serial chain (SESC), a representation of any multilink branched chain whose end-effector locates the center of mass. In order to construct the SESC for center of mass prediction, a Kinect and Wii balance board are used. The Kinect provides joint …

Wanted: Bromances: Impacts Of Hegemonic Masculinity On The Relationships Of Sophomore Men
Wanted: Bromances: Impacts Of Hegemonic Masculinity On The Relationships Of Sophomore Men
Stander Symposium Projects
Hegemonic masculinity is constructed in a way that pressures men into certain behaviors and mindsets. Traditional genders roles emphasized in hegemonic masculinity call for alcohol and drug abuse, unprotected sex, and other prohibited behavior (Edwards & Jones, 2009). There is a significant lack of research aimed specifically on the sophomore year experience for college students (Gardner et al., 2010). Hegemonic masculinity (Arxer, 2011) and its foundations give way to how men translate the pressures of masculinity into relationships. The research for this study revolved around the success of sophomore students and hegemonic masculinity. The study attempted to gain a new …
Tissi
Stander Symposium Projects
My thesis is a collection of short stories. The stories depict the lives of four children living in South Sudan trying to survive the genocide. One young girl has been brutally raped. A young boy is taking on the responsibility of raising his younger siblings. The third story shows a young boy who has been kidnapped and forced to be a child soldier. The fourth story is a story of hope. These stories are designed to show the chaos of genocide, and the difference that even a little assistance could make to the lives of the people in South Sudan.
Research Exercise: Timor-Leste, Un Women Peacekeepers, And The Gender Gap
Research Exercise: Timor-Leste, Un Women Peacekeepers, And The Gender Gap
Stander Symposium Projects
This presentation examines the role of women in United Nations peacekeeping operations, using the example of recent operations in Timor-Leste, and makes the case that there is a need for more female United Nations peacekeepers to partake in post conflict peacekeeping operations, democratization and social and political reconstruction in order to promote gender equality. Women are mostly sidelined or alienated in the participation of various peacebuilding and societal reconstruction. This creates a false conception that women are ignorant in such areas and have nothing to offer to peacekeeping efforts. However, women have played a vital role at the grassroots level …
The Role Of Nitrogen Vacancy In Optical Transitions In Gan
The Role Of Nitrogen Vacancy In Optical Transitions In Gan
Stander Symposium Projects
Nominally undoped n-type Gallium Nitride (GaN) layers grown by metalorganic chemical vapor deposition (MOCVD) on silicon substrates were studied. Thermal Admittance Spectroscopy (TAS) and Optical Admittance Spectroscopy (OAS) techniques were used to characterize these layers. Using Thermal Admittance Spectroscopy (TAS), a defect level was observed at Ec – 0.051 eV and this defect is correlated with the nitrogen vacancy (Nv) in GaN. The samples were illuminated with a monochromatic light with wavelengths (λ) ranging from 200 nm to 450 nm. The OAS spectrum was measured at different temperatures and with different excitation light intensities. The spectrum shows a maximum photoconductance …

Assessing Aesthetic Preferences For Faces With Measures Of Ocular Gaze
Assessing Aesthetic Preferences For Faces With Measures Of Ocular Gaze
Stander Symposium Projects
Though one may assume that the reactions to two nearly identical works of art would be similar, the medium in which art is presented can influence an individual’s perception of the work (Locher et al., 2006). The present study evaluates aesthetic preferences for faces, specifically, relating to those influenced by art; this is done by comparing reactions when viewing classic portraits and photographic renderings of those portraits. Simultaneously portraits and photographs of faces, matched for variables such as gender, artistic medium, ethnicity, face shape, facial hair, hair color, eye color, and facial position (full or profile), are shown to participants …
Behavioral Activation In A Homeless Shelter: An Example Of Engaged Scholarship
Behavioral Activation In A Homeless Shelter: An Example Of Engaged Scholarship
Stander Symposium Projects
A Behavioral Activation Program is implemented and evaluated at a homeless shelter. Behavioral Activation, which is based on operant conditioning, refers to “...a therapeutic process that emphasizes structured attempts at engendering increases in overt behaviors that are likely to bring [the person] into contact with reinforcing environmental contingencies and produce corresponding improvements in thoughts, mood, and overall quality of life” (Hopko et al., 2003, p. 700). Guided by the Psycho-Ecological Systems Model (Reeb & Folger, 2013), this interdisciplinary research project utilizes the participatory community action research strategy (Reeb, 2006), the pedagogical technique of service-learning (Reeb, 2010), and multidimensional assessment. Hypotheses …
