Uncovering Exceptional Predictions Using Exploratory Analysis Of Second Stage Machine Learning., Aneseh Alvanpour

Electronic Theses and Dissertations

Nowadays, algorithmic systems for making decisions are widely used to facilitate decisions in a variety of fields such as medicine, banking, applying for universities or network security. However, many machine learning algorithms are well-known for their complex mathematical internal workings which turn them into black boxes and makes their decision-making process usually difficult to understand even for experts. In this thesis, we try to develop a methodology to explain why a certain exceptional machine learned decision was made incorrectly by using the interpretability of the decision tree classifier. Our approach can provide insights about potential flaws in feature definition or …

Oil, Space, And National Imaginaries : Discursive Productions By Standard Oil New Jersey Post Wwii., Michael Poindexter

Electronic Theses and Dissertations

In a moment of self-representation, Standard Oil New Jersey commissioned a large photo ‘documentary’ project of nearly 80,000 images taken between the years 1943 to 1950. Produced for publication and exhibition, images captured “how oil seeped into every joint” of America, and displayed a specific landscape for post WWII economies. While a stable and centralized industry was ever more tied to the state’s idea of national security, Standard Oil needed a public relations project to address social concerns of big oil. This singular perspective on oil space is problematic. Community histories and social relations are seen through Standard Oil’s own …

An association was observed between a positive screen and race, ethnicity by region of origin, immigrant status, English as …

Analysis Of Gender And Gender-Related Implicit Leadership Themes In Hr Practitioner Literature : A Comparison Of The United States And Brazilian Hr Practitioner Publications., Flavia De Sousa E Castro Rossetti

Electronic Theses and Dissertations

Among the many factors studied in relation to the women and leadership equality gap are gender stereotypes, implicit leadership theories, and the congruity of gender role expectations (Eagly, & Karau, 2002). Multiple studies in the scholarly literature support the finding that men, rather than women, are more likely to be seen as leaders (Bierma, 2016; Eagly, & Schmidt, 2001), and this finding appears to be robust across some cultures (Schein, 2001). While the scholarly research on women and leadership has been burgeoning, few research studies have investigated how human resource (HR) practitioner literature addresses themes related to women and leadership …

Peeking Into The Other Half Of The Glass : Handling Polarization In Recommender Systems., Mahsa Badami

Electronic Theses and Dissertations

This dissertation is about filtering and discovering information online while using recommender systems. In the first part of our research, we study the phenomenon of polarization and its impact on filtering and discovering information. Polarization is a social phenomenon, with serious consequences, in real-life, particularly on social media. Thus it is important to understand how machine learning algorithms, especially recommender systems, behave in polarized environments. We study polarization within the context of the users' interactions with a space of items and how this affects recommender systems. We first formalize the concept of polarization based on item ratings and then relate …

A Meta-Analysis Of The Longitudinal Relationship Between Adolescent Depression And Academic Achievement., Rachel E. Buehner

Electronic Theses and Dissertations

Researchers in the fields of both education and mental health endeavor to develop and implement interventions which will bring children and adolescents greater academic success and optimally address mental health issues. Educators seek to target risk factors which might impede a student’s success in the classroom, while mental health providers seek to reduce issues within a child’s environment which might be risk factors for depression. Evidence for a cross-sectional relationship between adolescent depression and academic achievement is well-supported, with depression and achievement being negatively correlated in adolescents. The longitudinal relationship between these two variables is not fully understood, however. While …

A Multi-Period Facility Location Model For Service Organizations Operating In A Competitive Environment., Sven W. Brose

Electronic Theses and Dissertations

This thesis develops a multi-period, mathematical programming location model for facilities operating in a competitive environment. The objective is to maximize the profit in a variable demand environment. The solution of the problem can either be done in a robust or in a dynamic manner. A robust solution methodology forecasts the demand for all the periods in the planning horizon and provides a robust solution that may be suboptimal for any given period, but optimal when all the periods are taken into consideration. A problem with this approach is that it requires accurate forecast of demand for multiple periods into …

Data for this research were collected, studied, and analyzed. Data were examined to identify explanations for the lack of interest in agriculture among diverse students, and the lack of interest among school administrators and teachers to encourage studies in agriculture among the diverse. The analysis of data verified the existence of a real need for more disquiet in the differences of attitudes among diverse students regarding agriculture and agriculture programs, such as FFA. …

Development Of A Directional Bone Reaming System., Richard J Ackermann

Electronic Theses and Dissertations

Preparation of long bones such as the femur or tibia for placement of intramedullary devices for the treatment of fractures usually involves reaming with a series of central cutters driven by a drill-like device with a flexible shaft over a guide wire. The reamers sequentially enlarge the intramedullary canal into a tunnel of circular cross-section and a diameter appropriate for the procedure. The current technology is concentric, meaning that the system is self-centering within the original intramedullary canal and the expansion is symmetric with respect to the original centerline. A novel system for laterally deflecting the head of a 12mm …

Social Dynamics, Network Structure, And Information Diffusion In Fish Shoals., Matthew Jerome Hasenjager

Electronic Theses and Dissertations

Animal populations are often highly structured, with individuals differing in terms of whom they interact with and how frequently they do so. The resulting pattern of relationships constitutes a population’s social network. In this dissertation, I examine how environmental variation can shape social networks and influence information flow within them. In Chapter I, I review the history of social network analysis in animal behavior research, and discuss recent insights generated by network approaches in behavioral ecology. I focus on the fields of: social learning, collective behavior, animal personalities, and cooperation. Animal network studies are often criticized for a lack of …

Psychophysical Analysis Of Three Separate Anisotropic Patterns In Vision : Putting Visual Reference Frames In Conflict To Study The Class 1 And 2 Oblique Effects And The Horizontal Effect., Eleanor O'Keefe

Electronic Theses and Dissertations

This dissertation describes and investigates a debate about differences in the visual system’s anisotropic sensitivity to orientation as well as where and how the brain encodes visual orientation information. Three different visual perceptual patterns are discussed: the Class 1 and 2 oblique effects and the horizontal effect. The oblique effect is the ability to perceive cardinal orientations more easily than oblique orientations, and is found using narrowband stimuli. In the horizontal effect, oblique orientations are perceived most easily, horizontal orientations are perceived worst, and vertical orientations fall in-between, and is found using broadband stimuli. While the majority of authors refer …

American Emergency : Catastrophe And Culture In The U.S.A., From The Civil War To Hurricane Katrina., Lynda Kristian Mercer

Electronic Theses and Dissertations

This dissertation examines socio-cultural experiences of national disasters in the United States as they intersect with political rhetorics of democracy, to understand the forms and functions of state power as it is mediated through famous historical figures. Tracing the manifold possibilities from within and around the disruptive spacetimes of disaster, which sociologist Harvey Molotch describes in their ultimate function as societal “rationalizers” (371), I analyze catastrophes as contested spaces and histories that often get situated as variations on the “man vs. nature/god/man” binaries in public discourse. By analyzing the deployment of, and response to, such explanatory frameworks in the United …

Aspirations Into Action : Navigating Structures For Community Engagement At The University Of Louisville., Megan Faver Hartline

Electronic Theses and Dissertations

This dissertation analyzes the affordances of university structures based on how they value and support community engagement, focusing on common issues for community-engaged scholars. In this case study of the University of Louisville as an institution developing stronger structures for community engagement, I show that current efforts represent important starting points for how institutions support engagement, but I argue that they, and scholarly discussion about them, need to be deepened to meet the needs of engaged scholars. Toward that end, utilizing an institutional critique methodology informed by scholarship in institutional ethnography, I combine analysis of university policies and documents with …
