A Comparison Of Logistic, Ridge, And Lasso Regression With Heart Failure Risk Data: Effects Of Sample Size, Predictor Correlation, And Predictor Weight On Outcome Accuracy, Mahmoud M. Aljuhani

Electronic Theses and Dissertations

Logistic Regression (LR), LASSO regression, and RIDGE regression are standard classification techniques for predicting a dichotomous output. Since these methods are applied for similar purposes and have different features, it is crucial to evaluate the performance of these methods under different controlled conditions. With this information, researchers can apply the optimal method for specific conditions.

Following previous research, which reported the effects of conditions such as sample size and multicollinearity on the performance of the classification methods, this research focused on the effects of when sample size, level of predictor collinearity, and predictor variable weight are controlled on the performance …

Ideas In Communities: A Micro-Perspective On Entrepreneurial Ecosystems., Malcolm Muhammad

Electronic Theses and Dissertations

Entrepreneurial ecosystems are seen as a stimulant of regional economic growth. Theory-building efforts on entrepreneurial ecosystems has sufficiently established an understanding of the macro-environment; the environmental infrastructure and conditions that support productive entrepreneurship. However, there has been a disproportionate lack of focus on the micro- and group-level dynamics that impact individual entrepreneurs and ventures within ecosystem. This has limited the availability of evidence to explain how and when ecosystems emerge and function at a high level. Therefore, this dissertation examines three distinct microfoundations that can be found in entrepreneurial ecosystem literature – community, learning, and venture development – to move …

Sex And The Superman: Gender And The Superhero Monomyth, Christopher Maverick

Electronic Theses and Dissertations

Since the 1938 introduction of Superman, superheroes have been ever-present in American popular culture. Indeed, with the modern preponderance of comic book movies dominating the American cinematic box-office, superhero fantasy is arguably the most important genre of fiction being produced in the contemporary moment. Peter Coogan, Kurt Busiek and many other scholars have discussed the prominence and relevance of the superhero fantasy as a genre. Still others, including Umberto Eco and Marco Arnaudo, have asserted that the superhero is not so much a genre and as it is the evolution of mythology. In Sex and the Superman, I argue …

Parent Emotion Socialization And Emerging Adult Internalizing Symptoms: Differences And Moderation By Rurality, Cheston West

Electronic Theses and Dissertations

Emerging adulthood is a unique developmental period from late adolescence to late 20s during which individuals experience a multitude of developmental transitions and are at an increased risk for internalizing symptoms. Parent emotion socialization in childhood can also contribute to risk for internalizing symptoms and is shaped by parent gender and sociocultural context. Rurality is a sociocultural context that has implications for parenting, but less research has explored how parent emotion socialization varies by rurality. The present study examined maternal and paternal emotion socialization in relation to rurality and emerging adult internalizing symptoms. Participants were 270 emerging adults (18-29 years …

Importance Of The Microhabitat And Microclimate Conditions In The Northern Gray-Cheeked Salamander (Plethodon Montanus) Across An Elevation Gradient, Trevor Chapman

Electronic Theses and Dissertations

The southern Appalachian Mountains have among the highest salamander diversity in the world, largely due to local speciation in the family Plethodontidae. Plethodontid salamanders (i.e., lungless salamanders) are particularly sensitive to habitat climate conditions due to their reliance on cutaneous respiration, and their immediate environmental conditions (microhabitat) likely influence their dispersion and activity more than the large-scale atmospheric conditions. The Northern Gray-cheeked salamander (Plethodon montanus) is restricted to high elevations in the Appalachian Mountains. Our goal was to investigate the relationship between P. montanus and its microhabitat by examining behavioral preference for climatic conditions, characterizing the microclimate with …

Domestic Violence Against Men: Their Report Decision Making Process, Ngozi Aleke

Electronic Theses and Dissertations

Little or nothing is really known about a man’s victimization in a domestic violence situation. Generally domestic violence is viewed from the lens of a women with the typical idea that women are the victim while men, the perpetrators of violence. Overtime, this societal perception is beginning to subside as researchers have proven that men are also victims of domestic violence (Straus, Gelles, & Steinmetz,1980). Despite this revelation, not much is known about male victimization as most men prefer not to report their victimization. This study seeks to examine the reasons for not reporting victimization and the effect of this …

A Frayed Edge: A Qualitative And Poetic Inquiry Analysis Of White Antiracist Protest In 2020, Emily Katt

Electronic Theses and Dissertations

This multiphasic study explored the narratives of five first-time Black Lives Matter protesters demonstrating during the historic confluence of conflicts in 2020 America. After positioning the liminal 2020 circumstances within an antiracist research lens, the author analyzed, first through grounded theory and then secondarily through poetic inquiry, how these five participants described their protest experiences. The grounded theory phase yielded an overarching theory that first-time protestors experienced a dual process of unsuturing and of calling-out, with three subthemes categorized within each of these two processes. The author moved into analysis with the poetic inquiry phase, crafting poems guided by six …

Borderline Personality Disorder And Violent Crime: The Moderating Role Of Sex And Race, Genevieve Allison

Electronic Theses and Dissertations

People receiving treatment for substance use disorders (SUD) are at risk of justice involvement. Although it is well-established that borderline personality disorder (BPD) increases risk for criminal involvement, it is unclear whether this relationship exists among people with SUDs. Furthermore, prior research has found sex and race differences in the relationships between BPD and justice involvement as well as violence, but these moderators have not been explored within a substance using sample. The current study utilized a sample receiving SUD treatment to examine whether BPD is associated with prior violent charges and, if race and sex moderated this relationship. Results …

Understanding Racial Disparate Treatment Of Juvenile Interpersonal Violent Offenders In The Juvenile Justice System Using Focal Concerns Theory., Suzanne Overstreet
