Factors That Influence Graduation Rates At Northwestern College, Hailey Louw, Jennifer Schon

Celebration of Research

This project examines factors that influence graduation rates regarding behaviors and choices made in college as opposed to exogenous factors such as family income, race, etc. These factors also included responses from first-year students who took the Cooperative Institutional Research Program (CIRP) survey. Using data from 2013 - 2016 freshman admissions and combining this with CIRP responses from 2014 and 2016, there were found to be five factors related to behavior at college that influenced graduation rates.

Completion of registered hours, campus involvement, and high tuition discount rates had strong, positive correlations with whether the student graduated. Student participation in …

Relationship Between Higher Education And Health Insurance Coverage And Healthcare Utilization For Black Or African American Individuals, Emma Revoir

Psychology Student Works

Higher education may decrease mortality due to higher income and health insurance availability (Buckles et al., 2016). Education can increase understanding and utilizing health insurance (Gallo et al., 2020). There is a gap in how this relationship affects racial minorities. This study aims to understand how health insurance is affected by education level for Black or African American individuals.

The Association Between Sibling Relationships And Personality, Rebecca Ramsey

Psychology Student Works

Differences in self perception (specifically aggression) was discovered in participants with siblings, and no difference of intelligence, outgoing personalities, creativity, competitiveness and family orientation (Van Volkom, Guerguis, & Kramer, 2017). Sisters were found to have more empathy than the brothers along with higher intimacy, knowledge, and emotional support (Walęcka-Matyja, 2017). There is a gap in my research between sibling jealousy and depression, sibling negativity, and intimacy in young adulthood (Hamwey & Whiteman, 2020). My study examines the similarity of personality to siblings. Some personality traits may include jealousy, outgoingness, competitiveness, and creativity.

How Quality Of Paternal Relationship Impacts Depression Development In Adulthood, Rachel Lane

Psychology Student Works

Previous studies show that paternal involvement directly correlates to a decrease in the child’s probability of developing a mental illness (O’Gara, et.al. 2019). Research shows, the more supportive and the more affection a parent gives, the less likely a child is to develop depressive tendencies (Del Barrio, et. al. 2016) There is a gap in investigating whether or not having a loving father postpones the age at which someone is diagnosed with depression. This study provides insight into paternal closeness and the age at which someone is diagnosed with depression.

The Association Between Promiscuity And Marital Satisfaction, Shelby Kate Christopher

Psychology Student Works

Research has suggested that premarital cohabitation is linked to a heightened risk of divorce and dissatisfaction if it occurs with someone other than the marriage partner (Teachman, 2004). The number of partners is linked to marital dissatisfaction for both men and women (Legkauskas & Stankevičienė, 2008). Involvement in church groups is linked to a 5x increase in likelihood of abstinence (Paul et al, 2000). Previous studies have used small sample sizes with little diversity and few men. However, my research will use a large, diverse sample size with both men and women.

The Association Between Religiosity And Alcohol Use In Adolescents, Daphny Vang

Psychology Student Works

Research has found that the age and strength of religion directly correlate to the level of alcohol consumption(Mason & Windle, 2002). Previous studies show that adult women with stronger religious beliefs consume less alcohol compared to those with weaker religious beliefs (Mattila & et al., 2001). There is a gap in investigating the relationship between religiosity and alcohol use in adolescents. This study provides insight into the relationship between religiosity and alcohol consumption with adolescents.

The Relationship Between Adults Education Level And Their Mental Health Status, Kelsey Bergan

Psychology Student Works

Research has shown that those with a higher education are more likely to seek out sources to help them with mental disorders (Ibrahim, et al., 2019; Neimeyer, et al., 2011). Previous studies have found that students with a lower GPA show signs of depression, anxiety and eating disorders (Eisenberg, Globerstein & Hunt, 2009). There is a gap in investigating the relationship between education level and an adult’s mental health experiences. This study will provide insight to the relationship between an adults education level and their mental health.

The Relationship Between Adolescents’ Participation In Religious/Spiritual Activities And Mental Health As An Adult, Tiara Lamb

Psychology Student Works

Many receiving mental health treatment across the U.S. see spirituality and religion as very helpful in supporting their mental state (Oxhandler et al., 2021). How often black Americans attended church in adolescence is related to how as a young adult they could spiritually handle mentally stressing situations (Alexander, 2017). There’s a gap in previous studies because most of them study specific groups rather than using a representative sample of the U.S. In addition, there is a lack of studies investigating the relationship between adolescent religiosity/spirituality and adult mental health. This study uses a representative sample and investigates the association between …

The Association Of Maternal Relationships And Acts Of Violence In Adults, Cameron Shores

Psychology Student Works

Through research it has been found that people who do not feel close to their parents are more likely to react with violence (Cano-Lozano et al., 2020). Studies have also shown that people who reported adverse relationships as children, tend to have more violence-related outcomes (Duke, 2010). There is currently a gap in explaining the association between maternal closeness and violent tendencies. This study is meant to help fill that gap and bring cognizance to the relationship between maternal closeness and violence.

Empirically Adjusted Weighted Ordered P-Values Method, Wimarsha Jayanetti, Sinjini Sikdar, N. Rao Chaganty

College of Sciences Posters

Recent advancements in high-throughput technologies have enabled simultaneous inference of thousands of genes. With the abundance of public databases, it is now possible to rapidly access the results of several genomic studies, each of which includes the significance testing results of a large number of genes. Researchers frequently aggregate genomic data from multiple studies in the form of a meta-analysis. Most traditional meta-analysis methods aim at combining summary results to find signals in at least one of the studies. However, often the goal is to identify genes that are differentially expressed in a consistent pattern across multiple studies. Recently, a …

I predict that when teams play at home, there will be a significant difference in their win ratio and goals scored.

Flood Risk Prediction In Southern Louisiana Using Support Vector Machines, Claire Dorsett

Mathematics Senior Capstone Papers

Flooding in Southern Louisiana is a growing concern as violent weather becomes more frequent. According to the Environmental Protection Agency (EPA), Louisiana soils have become drier and annual rainfall trends have increased, which may lead to more severe flooding in the coming years. In light of this change in weather trends, flood prediction has become increasingly important for the public’s safety. The focus of this paper is to apply the Support Vector Machine (SVM), a machine learning technique, to classify flood risks based on water gage height, wind speed and direction, and time of the year. In this paper, the …

A Monte Carlo Analysis Of Seven Dichotomous Variable Confidence Interval Equations, Morgan Juanita Dubose

Masters Theses & Specialist Projects

Department of Psychological Sciences Western Kentucky University There are two options to estimate a range of likely values for the population mean of a continuous variable: one for when the population standard deviation is known and another for when the population standard deviation is unknown. There are seven proposed equations to calculate the confidence interval for the population mean of a dichotomous variable: normal approximation interval, Wilson interval, Jeffreys interval, Clopper-Pearson, Agresti-Coull, arcsine transformation, and logit transformation. In this study, I compared the percent effectiveness of each equation using a Monte Carlo analysis and the interval range over a range …
