A Historical And Practical Analysis For Neuromarketing In Business Practices Today, Scott Wicinski
A Historical And Practical Analysis For Neuromarketing In Business Practices Today, Scott Wicinski
Marketing Undergraduate Honors Theses
What thoughts come to your mind when you think of the term neuromarketing? In a digital age where personal privacy seems to be diminishing and data exploitation appears to be rising, many people are skeptical about businesses' attempts to combine neurology, psychology, and business. This skepticism is unfortunately, legitimate. Our history reveals plenty of occasions where businesses have exploited their customers through unethical means and traded valuable relationships and resources for profits. However, despite the flaws business can introduce, business is arguably still the most powerful tool for creating value in a community. Through business, customers have had access to …

A Country Prospering On Abuse: Migrant Worker Exploitation And Labor Reform In Qatar, Emma Towe
A Country Prospering On Abuse: Migrant Worker Exploitation And Labor Reform In Qatar, Emma Towe
Marketing Undergraduate Honors Theses
The countries of the Gulf Cooperation Council rely on migrant workers to drive their economies and perform hard labor while simultaneously abusing these workers through the kafala (sponsorship) system. Qatar is not an exception to this rule, even as labor reforms are being implemented. When Qatar was awarded the responsibility of hosting the 2022 FIFA World Cup, an international spotlight on labor abuses followed. Although Qatar has responded by enacting labor reforms, strong evidence shows continued abuse and lax enforcement of new polices. While the economy of Qatar thrives, overworked, underpaid migrant workers, who have little to no rights, continue …
Oaths And Evasion: Variable Honesty In Tax Evasion Games, Logan Krebs
Oaths And Evasion: Variable Honesty In Tax Evasion Games, Logan Krebs
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Previous research has indicated that an ex-ante pledge of honesty reduces the likelihood that participants will lie during a lab experiment. We show that a bandwagon effect, occurring when participants know that others are acting dishonestly, can erode the positive effects of honesty oaths. Taxpayers do not make their reporting decisions in a vacuum. They have access to information concerning how others in the community are behaving and develop perceptions around this information. We add these realistic features to a tax evasion game involving an ex-ante honesty oath. Results indicate that social context can reduce the positive effects of honesty …
The Ethics Of Masking During A Pandemic, Mason Bennett
The Ethics Of Masking During A Pandemic, Mason Bennett
Philosophy Undergraduate Honors Theses
The COVID-19 pandemic has been disastrous, approaching a million deaths in the United States alone, and has demonstrated the world’s lack of preparation for a severe airborne virus. Countermeasures to infection are important to implement in order to lessen loss of life, but also must be justified and shown to be ethical. A countermeasure which is especially viable is wearing masks because of their high efficacy in preventing disease transmission compared to their relatively low restriction of liberty; studies have shown that mask wearing effectively impairs the spread of airborne pathogens and creates little physical or social harm. I argue …

Decision Making Under Uncertainty Among Agricultural Commodity Traders, Marei Undine Houpert
Graduate Theses and Dissertations
Understanding how humans behave has received increased attention in research in the most recent decades. While insights into human behavior are essential for the functioning of markets, these insights are also crucial for the guidance of policymaking and public spending decisions to ensure that markets are fair and accessible for all. This research has the unique opportunity to use a dataset of commercial grain trader transactions to study the decision-making and behavior of commercial traders in agricultural commodity markets rather than institutional investors or speculators.
Paper one focuses on the performance of commercial grain traders and their ability to perform …
Weight Management Program Using Myfitnesspal© In A Rural Primary Care Setting, Taylor Rittman
Weight Management Program Using Myfitnesspal© In A Rural Primary Care Setting, Taylor Rittman
The Eleanor Mann School of Nursing DNP Capstone Projects
Obesity is a growing health concern that is linked to the development of chronically debilitating physical and mental illnesses. Obesity is a result of a long-term positive imbalance between energy intake and energy expenditure. Evidence has shown more than one third of U.S. adults suffer from obesity. Primary care providers in the United States report being overburdened in treating obesity, citing a lack of time, structured approach, and structured resources. Furthermore, the disparities in obesity are even more prevalent in rural areas where older adults are the fastest growing part of the population at risk for this disease. Evidence indicates …
Effectiveness Of A Frailty Assessment Index To Predict Early Readmission Rates In Frail And Older Adult Renal Transplant Patients, Marilyn Barnett
Effectiveness Of A Frailty Assessment Index To Predict Early Readmission Rates In Frail And Older Adult Renal Transplant Patients, Marilyn Barnett
The Eleanor Mann School of Nursing DNP Capstone Projects
Background: Renal transplantation is a complex intervention integrating both medical and surgical modalities, and is considered the treatment of choice for many individuals with end-stage renal disease. The complicated care of patients undergoing renal transplantation puts them at risk for adverse outcomes including infection, allograft loss, and a greater risk for some types of cancer. Evaluating patients to ensure they have the ability and support to cope with the stress of surgery and recovery, is an important part of determining the most appropriate candidates to receive the limited supply of organs available. Frailty has increasingly been identified as a predictor …

Improving Depression Screening And Follow-Up Care In Underserved Populations, Alicia D. Hankins
Improving Depression Screening And Follow-Up Care In Underserved Populations, Alicia D. Hankins
The Eleanor Mann School of Nursing DNP Capstone Projects
Depression is a substantial source of financial, emotional, and physical burdens to patients and their families worldwide. It also disproportionately affects economically disadvantaged populations. To combat the depression crisis, The United States Preventive Services Task Force (USPSTF) published guidelines to boost depression screenings of all patients presenting for healthcare services. A review of literature and the completed needs assessment confirmed low rates of depression screening in the rural primary care sector. This project took place in an outpatient primary care facility in rural Arkansas, where current depression screening tools were not being used. The goal was to increase the percentage …
Development And Implementation Of A Protocol For Denosumab Administration In An Outpatient Infusion Clinic, Erin Stavrakas
Development And Implementation Of A Protocol For Denosumab Administration In An Outpatient Infusion Clinic, Erin Stavrakas
The Eleanor Mann School of Nursing DNP Capstone Projects
Denosumab, or Prolia, is a medication given to increase bone mineral density (BMD) and prevent fracture risk in patients with osteoporosis. Guidelines for monitoring of side effects, data on long-term effects, and appropriate precautions are still being researched and developed. Healthcare teams are often unaware of preventative care measures to guide informed clinical decision making and patient care management. The recognized gap in care also reduces the standardization of health care delivery in clinics administering Prolia; this gap can lead to errors and miscommunication between patients and healthcare teams an increased risk for side effects. The aim of this translation …
Minority Stress: A Model For Understanding Sexual Minority Adolescents’ Mental Health, Sean N. Weeks
Minority Stress: A Model For Understanding Sexual Minority Adolescents’ Mental Health, Sean N. Weeks
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Taken together, the three papers included in this dissertation offer an investigation of sexual minority adolescents’ stress as a predictor of adverse mental health outcomes (Paper 1), as being influenced by school and home climates (Paper 2), and as a measurable model for stress across levels (Paper 3). Results from this series of studies generally support theory and findings from other studies in that minority stress was found to be a meaningful predictor of mental health in sexual minority youth and that school and home climates were found to be important for understanding sexual minority youth wellbeing. However, the current …

Assessing Flooding Impact To Riverine Bridges: An Integrated Analysis, Maria Pregnolato, Andrew O. Winter, Dakota Mascarenas, Andrew D. Sen, Paul Bates, Michael R. Motley
Civil and Environmental Engineering Faculty Research and Publications
Flood events are the most frequent cause of damage to infrastructure compared to any other natural hazard, and global changes (climate, socioeconomic, technological) are likely to increase this damage. Transportation infrastructure systems are responsible for moving people, goods and services, and ensuring connection within and among urban areas. A failed link in these systems can impact the community by threatening evacuation capability, recovery operations and the overall economy. Bridges are critical links in the wider urban system since they are associated with little redundancy and a high (re)construction cost. Riverine bridges are particularly prone to failure during flood events; in …
United States V. Black Jack: Poverty And Welfare In The St. Louis Courts, Kyle Melles
United States V. Black Jack: Poverty And Welfare In The St. Louis Courts, Kyle Melles
Mendel Sato Research Award Projects
The 1974 United States v. City of Black Jack, Missouri case and the rhetoric around welfare, race, and “white flight” showed how racial attitudes contributed to poverty in St. Louis. Residents incorporated Black Jack, a small town in North St. Louis County, in 1970 with a demographic of 98.8% white and .2% black. The Citizens for the Incorporation of Black Jack pushed for township to block the Park View Heights plan for a federal Section 236 housing development cosponsored by St. Mark’s Methodist Church of Florissant and the United Methodist Ministry in St. Louis to provide low to middle-income residents …

Vectors, Pathogens And Climate Change: How Will Human Health Be Affected?, Joseph T. Barry
Honors Projects
This paper details how ongoing climate change will continue to affect the future of humanity. More specifically, this paper seeks to begin a conversation about how climate change impacts vectors and vector-borne pathogens and how both of these ultimately impact the future of human health. Three different vectors and three different pathogens are compared to provide an overview of how climate change may benefit these vectors and their associated pathogens. The vectors species selected for this comparative study are: (i) mosquitoes (Diptera, family Culicine), (ii) ticks (superorder Parasitiformes, order Ixodida), and (iii) kissing bugs (Hemiptera, subfamily Triatominae). Yellow fever virus …
The Role Of Perceived Organizational Support In Anxiety And Depression, Chloe Dingens
The Role Of Perceived Organizational Support In Anxiety And Depression, Chloe Dingens
Honors Projects
This study seeks to explore the relationships between employees’ levels of perceived organizational support (POS) and their levels of anxiety and depression. Eisenberger et al. (1986, p. 500) defines POS as an employee's perception about how much the organization they work for values them and cares about their well-being. It was hypothesized that workers who experience higher POS will report lower anxiety and depression. Survey data were collected from 494 adults who worked an average of 39.9 hours per week (SD = 8.3). Participants completed survey measures of POS, anxiety, and depression, and reported demographics (e.g., job tenure) that were …
The Quest For New Music: A Recommendation Algorithm For Spotify Users, Ian Curtis
The Quest For New Music: A Recommendation Algorithm For Spotify Users, Ian Curtis
Honors Projects
Music is one of the rare forms of communication that can be understood on a profound level by anyone; it has the power to cause significant emotional effects, to spark inspiration, to ignite change, to spread knowledge, and more, even regardless of song language. A popular subject of research in music pertains to recommendations; determining a song a listener would enjoy is not an easy task. Moreover, certain factors may influence a user's satisfaction with recommended songs and their likelihood to continue using a service. Focusing on the major streaming service Spotify, we build a K-Means clustering algorithm to recommend …
Identifying The Isotopic Signature Of Lake-Effect Precipitation In Shallow Groundwater, Andrew Brown
Identifying The Isotopic Signature Of Lake-Effect Precipitation In Shallow Groundwater, Andrew Brown
Honors Projects
Three different stable isotopes of water occur in nature, with the majority of water on Earth containing the oxygen isotope 16O. These isotopes have slightly differing physical and chemical properties. H2O with heavier oxygen isotopes should theoretically precipitate earlier than lighter isotope H2O, meaning this natural process should allow for the observation of the magnitude of effects of lake-effect precipitation on the basis of water isotope differences. Furthermore, it may allow for better understanding of the significance lake-effect precipitation plays in recharging shallow aquifers. In this study, patterns of lake-effect precipitation from Lake Michigan were observed in a collection of …
An Overview Of The Current Research On Epiphyte Ecology, Kelsey Inman-Carter
An Overview Of The Current Research On Epiphyte Ecology, Kelsey Inman-Carter
Honors Projects
Epiphytes are non-parasitic, photosynthetic organisms that depend on other photosynthetic host organisms for support. Epiphytes can be found both in aquatic and terrestrial habitats. The interactions between epiphytes and their hosts can vary based on both their habitat and the features of individual hosts. This review explores the many facets of epiphyte research, including: the diversity of epiphytes in aquatic and terrestrial habitats; the effects of host-epiphyte interactions on the hosts; and the abiotic and biotic interactions that together determine epiphyte community composition.
Effects Of Branched Chain Amino Acid Supplementation On Post-Exercise Muscle Recovery And Muscle Growth, Kyla N. Marquez
Effects Of Branched Chain Amino Acid Supplementation On Post-Exercise Muscle Recovery And Muscle Growth, Kyla N. Marquez
Honors Projects
BCAA supplements are composed of three main essential amino acids, including leucine, isoleucine, and valine. The concept of BCAA supplementation comes from the fact that essential amino acids cannot be made by the body and must be derived from food and diet, as amino acids are the building blocks of proteins and muscle. Thus, by increasing intake of these essential amino acids, BCAAs are believed to reduce the effects of exercise-induced muscle damage (EIMD) by increasing availability of these important compounds. However, BCAAs are not approved by the Food & Drug Administration (FDA) as the FDA does not regulate dietary …

The purpose of this project was to develop a food allergy informational poster for use in the classroom. The Center for Disease Control has estimated that an average of two children in each public school classroom in the United States struggled with a food allergy. Meanwhile, other researchers found that 25% of first-time anaphylaxis episodes occurred in classrooms. This Honors Project was developed to address the informational gap concerning anaphylaxis that occurs at schools. The methodology was literature review. The Honor Project's outcome was the informational poster, Know the Signs of an Allergic Reaction: Anaphylaxis, as well as the supplemental …
The Effect Of One Night Of Sleep Fragmentation On Aerobic Exercise Performance, Tara L. Thompson
The Effect Of One Night Of Sleep Fragmentation On Aerobic Exercise Performance, Tara L. Thompson
Senior Honors Projects, 2020-current
Purpose: People can experience sleep fragmentation for many reasons. The negative effect this has on a person’s daytime function and sleepiness has already been studied extensively, yet there is little on the effect it has on a person’s aerobic athletic performance. Many athletes experience frequent wake-ups in the middle of the night, due to nerves and other factors, which could potentially affect their performance.
Methods: For each of the eight subjects, testing began with a VO2max test and a familiarization trial. Following this, subject’s then participated in two experimental trials, where they were randomly assigned either a night of sleep …
Tree Species Diversity Increases With Conspecific Negative Density Dependence Across An Elevation Gradient, Joseph A. Lamanna, F. Andrew Jones, Davod M. Bell, Robert J. Pabst, David C. Shaw
Tree Species Diversity Increases With Conspecific Negative Density Dependence Across An Elevation Gradient, Joseph A. Lamanna, F. Andrew Jones, Davod M. Bell, Robert J. Pabst, David C. Shaw
Biological Sciences Faculty Research and Publications
Elevational and latitudinal gradients in species diversity may be mediated by biotic interactions that cause density-dependent effects of conspecifics on survival or growth to differ from effects of heterospecifics (i.e. conspecific density dependence), but limited evidence exists to support this. We tested the hypothesis that conspecific density dependence varies with elevation using over 40 years of data on tree survival and growth from 23 old-growth temperate forest stands across a 1,000-m elevation gradient. We found that conspecific-density-dependent effects on survival of small-to-intermediate-sized focal trees were negative in lower elevation, higher diversity forest stands typically characterised by warmer temperatures and greater …

Evolved Resistance To A Novel Cationic Peptide Antibiotic Requires High Mutation Supply, Alfonso Santos-Lopez, Melissa J. Fritz, Jeffrey B. Lombardo, Ansen H.P. Burr, Victoria A. Heinrich, Christopher Marshall, Vaughn S. Cooper
Biological Sciences Faculty Research and Publications
Background and Objectives
A key strategy for resolving the antibiotic resistance crisis is the development of new drugs with antimicrobial properties. The engineered cationic antimicrobial peptide WLBU2 (also known as PLG0206) is a promising broad-spectrum antimicrobial compound that has completed Phase I clinical studies. It has activity against Gram-negative and Gram-positive bacteria including infections associated with biofilm. No definitive mechanisms of resistance to WLBU2 have been identified.
Methodology
Here, we used experimental evolution under different levels of mutation supply and whole genome sequencing (WGS) to detect the genetic pathways and probable mechanisms of resistance to this peptide. We propagated populations …
