Model Of Cost-Effectiveness Of Mri For Women Of Average Lifetime Risk Of Breast Cancer, Mckenna L. Kimball

Scholarly and Creative Works Conference (2015 - 2021)

Background: Mammography is the current standard for breast cancer detection however magnetic resonance imaging (MRI) is a more sensitive method of breast imaging. Despite MRI’s increased sensitivity, MRI has more false positives and higher costs. The purpose of this study was to determine if MRI or MRI in conjunction with mammography was a cost-effective solution for breast cancer detection in women with average lifetime risk of breast cancer.

Methods: A mathematical model was used to compare annual mammography, annual MRI, and mammography and MRI on alternate years. The model included the natural history of breast cancer, screening by mammography …

The Plight Of The Lucluc: Examining The Deadly Mystery Of Nodding Syndrome, Ethan K. Mcgann

Senior Honors Theses

Nodding syndrome (NS) is an emerging epidemic neurological disease that is shrouded in mystery. It is currently only found in the post-conflict regions of South Sudan, northern Uganda, and Tanzania. NS occurs in children from the ages of five to fifteen and is characterized by a loss of motor control in the neck muscles. Seizure episodes can range in intensity from atonic to tonic-clonic, and the onset of the first episode generally marks the beginning of a decline in the child’s physical and mental health. NS is a progressive disease that generally results in physical wasting, stunted growth, behavioral difficulties, …

Flavour Chemicals In Electronic Cigarette Fluids, Peyton A. Tierney, Clarissa D. Karpinski, Jessica E. Brown, Wentai Luo, James F. Pankow

Chemistry Faculty Publications and Presentations

Background: Most e-cigarette liquids contain flavour chemicals. Flavour chemicals certified as safe for ingestion by the Flavor Extracts Manufacturers Association may not be safe for use in e-cigarettes. This study identified and measured flavour chemicals in 30 e-cigarette fluids.

Methods: Two brands of single-use e-cigarettes were selected and their fluids in multiple flavour types analysed by gas chromatography/mass spectrometry. For the same flavour types, and for selected confectionary flavours (eg, bubble gum and cotton candy), also analysed were convenience samples of e-cigarette fluids in refill bottles from local ‘vape’ shops and online retailers.

Results: In many liquids, total flavour chemicals …

Courtship In The Borderlands: Hollistic Intimate Space Creation Within Courtship Ideaologies, Alejandro Sánchez

The Compass

While telling me the story of how she met her husband, Mrs. Aguilar told me “I really feel bad for your generation, they are missing out on falling in love.” She was referring to the courtship practices, or the social regulation and cultural markers between two individuals who create a social relation developing a “relationship.”1 She was comparingthe courtship practices of her generation to that of mine and her statement is reflective of the changes in the cultural environment. From courting, a “relationship” can develop. Its dimensions are defined by the mediation between cultural norms and the agent, and can …

Strategies For Leaders To Counter Social Loafing Through The Use Of Organizational Citizenship Behavior: A Literature Review, Richard Hildreth

The Compass

Social loafing (SL) is a counterintuitive phenomenon that describes a decrease of efficiency observed in both small groups and large organizations. Research over the past century has increased our understanding of SL and identified antecedent factors that appear to reduce or exacerbate its effect. Subsequent organizational models have beenconceived and evolved, starting with organizational citizenship behavior (OCB), which led toward contextualperformance (CP), and recently to contextual and citizenship performance (CCP). Each type of model can provide valuable insight explaining employee behavior and under which contexts SL occurs. Research shows that OCB has improves organizational productivity and competitiveness, due to organizational …

Drinking And Game Day: The Expansion And Solution To Alcohol Abuse In Collegiate Sporting Events, Karan Arul

The Compass

For the typical American sports fans, a night out to watch a college sporting event involves a celebration of athleticism, spirit, and teamwork. However, as of the 21st century, the act of purchasing and consuming alcohol has become increasingly complimentary to “enjoying the game” in a collegiate sports stadium. In the United States, the National Collegiate Athletic Association (NCAA) is the frontrunner in proliferating collegiate athletics. Yet, the NCAA and its over 1200 member schools “enjoy great profitability from selling and advertising alcohol.”1 As college sporting events continue to rival their professional counterparts in popularity and allegiance, attending a college …

Faculty Publications

This study examined the association between nutritional awareness and diet quality, as indicated by energy density, dietary diversity and adequacy to achieve dietary recommendations, while considering the potentially important role of socioeconomic status (SES). Data were derived from 1351 subjects, aged 18–69 years and enrolled in the ORISCAV-LUX study. Energy density score (EDS), dietary diversity score (DDS) and Recommendation Compliance Index (RCI) were calculated based on data derived from a food frequency questionnaire. Nutritional awareness was defined as self-perception of the importance assigned to eating balanced meals, and classified as high, moderate, or of little importance. Initially, a General Linear …

Handling Human Hacking: Creating A Comprehensive Defensive Strategy Against Modern Social Engineering, Charles Snyder

Senior Honors Theses

Social engineering is one of the most devastating threats to any company or business. Rather than relying upon technical flaws in order to break into computer networks, social engineers utilize a suave personality in order to deceive individuals through clever conversation. These devious conversations frequently provide the attacker with sufficient information to compromise the company’s computer network. Unlike common technical attacks, social engineering attacks cannot be prevented by security tools and software. Instead of attacking a network directly, a social engineer exploits human psychology in order to coerce the victim to inadvertently divulge sensitive information. Further complicating the issue, the …

Essential Oils From Apple Mint (Mentha Suaveolens) And Passionflower Fruit (Passiflora Incarnata): Studies On Cognition, Coordination, And Chemical Components., Evelyn F. Patrick *, Jessie Bowers *, Shannon Read *, Brett R. Lackey, Christine Murphy, Sandra L. Gray

Journal of the South Carolina Academy of Science

Plant essential oils (EO) are used as perfumes, lotions and air fresheners because of their pleasant aromas, but EO also have the ability to elicit changes in mood and behavior. These activities are influenced by the mode of administration and by multiple signaling pathways. The EO aromas from organically grown apple mint (Mentha suaveolens) and passionflower fruit (Passiflora incarnata) were assessed for their effects on cognition and coordination. Participants completed two tasks designed to test working memory and bimanual task efficiency in rooms infused with apple mint, passionflower fruit or control EO. Bimanual coordination was assessed using the Intercept2 program …

Montgomery County, Ohio’s diabetes prevalence outpaces the nation, and the incidence of adult obesity approaches 1/3. Access to healthy food in the impoverished neighborhood surrounding Dayton’s Good Samaritan Hospital, the site of the Family Medicine residency, is important when educating about health lifestyle. The purpose of this project was to determine whether the area was a food desert and to evaluate the implications of the label.

Confessions Of A Sorority Woman: Impacts Of Hazing On New Members Of Panhellenic Greek Lettered Organizations

Stander Symposium Projects

The purpose of this study was to examine how Panhellenic Greek lettered organizations might choose to haze their new members and how being hazed impacted a new member, physically and mentally. Participants responded to a web-based survey that asked individuals to identify what they believed constitutes hazing, hazing acts they have been asked to engage in, and outcomes of joining a Panhellenic organization. Both new members and initiated members received the survey. For data analysis, participant responses were compared using an Analysis of Variance (ANOVA). New members of Panhellenic Greek-lettered organizations defined organizational unity and mental/emotional instability as an outcome …

Characterization Of The P53 Signaling Pathway In Urodele Amphibians During Lens Regeneration

Stander Symposium Projects

Urodele amphibians such as the red spotted newt, Notophthalmus viridescens, and axolotl are commonly used to study organ regeneration due to their remarkable ability to regenerate organs such as limb, tail, spinal cord and lens. The newt is able to regenerate the lens solely from dorsal iris pigmented epithelial cells in 30 days following removal. Axolotls, neonate salamanders, invoke curiosity because they can only regenerate their lens two weeks post hatching although they have the same regeneration potential as newts for limb, tail, and spinal cord. Using these animal models the role of the p53 protein, a tumor suppressor protein, …

Defective Proventriculus (Dve) A New Member Of Dv Patterning In The Eye

Stander Symposium Projects

In multi-cellular organisms, axial patterning is required to generate three-dimensional organ from its primordia during organogenesis. Drosophila eye serves as an excellent model to study patterning and growth. In Drosophila eye, Dorso-ventral (DV) patterning is the first lineage restriction event in the developing eye. The early eye primordium begins with the default ventral fate on which the dorsal eye fate is established by expression of a GATA-1 transcription factor, pannier (pnr). We have identified defective proventriculus (dve), a K50 homeodomain gene as a novel dorsal gene that plays a crucial role in Drosophila eye development. We have found that dve …

Diminishing The Discipline Gap: Restorative Justice As A Promising Alternative In One Urban School

Stander Symposium Projects

Across the nation, the education system is responding to student misbehavior with zero tolerance policies that parallel the punitive practices found in the juvenile and criminal justice systems. Zero tolerance policies have contributed to the “discipline gap,” wherein schools punish racial and ethnic minorities more often and more severely than they punish whites. One alternative to punitive punishment is restorative justice, which aims to foster respect, responsibility, and empathy in members of school communities. This project evaluates the relationship between restorative justice and out-of-school suspension rates in an urban school district. It also serves as one of the few studies …

A Study In Dividend Investment Strategieshigh Yield Vs. High Dividend Growthfor The Period 2008 - 2014

Stander Symposium Projects

From a total return perspective, there is an on-going debate among financial analysts as to which is the better strategy: (1) investing in high yield stocks or (2) investing in stocks with high dividend growth rates. Since stocks with high dividend growth rates also tend to be lower yielding stocks, the strategy debate is often more about low vs. high levels of yield. In this study I test several hypotheses: (1) low yield stocks outperform high yield stocks, (2) high dividend growth rate stocks outperform low dividend growth rate stocks, (3) high dividend growth rate stocks outperform high dividend yielding …

A Self Organizing Maps Approach To Segmenting Tumors In Computed Tomography (Cat) And Magnetic Resonance Imaging (Mri) Scans

Stander Symposium Projects

Studies and explorations of human visual perception have been the main source of inspiration for computer vision algorithms. Understanding how the human brain represents basic attributes of objects helps in developing computer vision algorithms for automatic object interpretation and understanding. Human visual perception is based on the neural coding of fundamental features, such as object boundaries, color, orientation, shape, etc. Thus, finding the contours and boundaries of objects provides the first step for object recognition and interpretation. Form here, the idea of this research inspired to introduce an automatic boundary detection technique based on active contours that is designed to …

Intention Based Upper-Limb Exoskeleton

Stander Symposium Projects

Exoskeletons, a wearable robot that intelligently augments the physical power of a human being. These robots are used in military and similar applications, but the challenge remains that how to make the human-machine interaction safe and sound. The idea behind the 'intention based approach' is that an array of compliant force sensors will continuously monitor the movement of the limb and then map the filtered data to drive the respective actuator which in turn helps in doing the same 'movement' with augmented power and better stability. Additionally a 9 DoF IMU, continuously map the end effector's spatial position as an …

Where Do I Belong? Lgbt Experiences In On-Campus Housing

Stander Symposium Projects

Studies have shown that for many who identify as gay, lesbian, bisexual, transgender and/or Queer (LGBTQ) students, navigating through higher education is a difficult task full of opposition and challenges preventing them from achieving their full academic potential. While these challenges present themselves through several outlets on campus, Housing and facilities is one of the main areas that have the potential to challenge and educate students as they connect their learning experiences to their living realities. For students who are feeling that they do not belong, or that there is no “space” for them, navigating higher education and the campus …

Race Or Culture? African American Student Experiences At A Predominantly White Institution

Stander Symposium Projects

This qualitative study explores the experiences of African American students who attend predominantly White institutions. Several factors could benefit, hinder and/or frustrate African American students who have decided to pursue and complete higher education at a predominantly White institution. However, the responsibility of administrators to assist African Americans with this transition continues to be of major importance as they must take into consideration student experiences and cultures. The social, cultural, and academic adjustment process for African Americans varies based on the students’ culture, personal backgrounds and individual experiences not just race. For this research study African American students attending a …

Closing The Gap: Examining Humanities Majors' Perceptions Of Career Services

Stander Symposium Projects

Connecting one’s degree in the humanities to a career path can be an ambiguous challenge in a society focused on job preparation. Career services offices in higher education institutions are at the forefront of helping students advance in their career development, yet little research has explored student insights and perspectives about these resources. This study explores humanities majors’ perceptions, insights, and knowledge of career services at a private institution in the Midwest. A mixed methods approach provided evidence of over 125 students’ knowledge and utilization of career services while supported by in-depth insights of students' experiences. Humanities majors revealed their …

Too Close For Comfort: The Effect Of Threatening

Stander Symposium Projects

Stereotypes are relied upon to help guide people through their social world. Although typically characterized as unfavorable, stereotypes can serve a number of beneficial functions. Stereotypes allow people to quickly process new information about novel individuals, environments, or events by applying preexisting stereotype-consistent information. Processing new information quickly is essential in novel or unfamiliar situation because it helps determine how to best react. While there are a number of beneficial qualities of stereotypes, a disadvantage of stereotypes is that they can potentially lead to distortions in reality. Stereotypes play an active role in the evaluation of stimuli (e.g., persons), but …

Hate Crime Laws: What Are They And Who Do They Protect?

Stander Symposium Projects

Tremendous disagreement and confusion regarding hate crime laws and the groups protected by them persist. We investigated perceptions of what constitutes a hate crime and whether these standards are applied consistently. Participants read and responded to brief scenarios describing offenses committed by majority or minority group members against others (majority or minority group members). Although support for the exploratory hypotheses was not found, interesting patterns emerged with respect to gender differences.

A Time Series Analysis Of Service Consumption Expenditures As Determinants Of The Consumer Discretionary And Consumer Staples Sector Price Movements, 2004-2014.

Stander Symposium Projects

A growing portion of U.S. Consumer income is spent on services. Both directly and indirectly these expenditures effect the stock market prices of firms in the consumer discretionary and consumer staples sectors. The objective of this study, therefore is to determine if the market prices of these two sectors co-vary with the growth in consumer services expenditures. The period of analysis is 2004-2014. Quarterly pricing and expenditure level data are used in the analysis. Using regression analysis, the hypothesis to be tested is service expenditures and discretionary and staples sector prices co-vary directly with each other. We expect the b …
