Comparison Of Correlation, Partial Correlation, And Conditional Mutual Information For Interaction Effects Screening In Generalized Linear Models, Ji Li

Graduate Theses and Dissertations

Numerous screening techniques have been developed in recent years for genome-wide association studies (GWASs) (Moore et al., 2010). In this thesis, a novel model-free screening method was developed and validated by an extensive simulation study. Many screening methods were mainly focused on main effects, while very few studies considered the models containing both main effects and interaction effects. In this work, the interaction effects were fully considered and three different methods (Pearson’s Correlation Coefficient, Partial Correlation, and Conditional Mutual Information) were tested and their prediction accuracies were compared.

Pearson’s Correlation Coefficient method, which is a direct interaction screening (DIS) procedure, …

The Effects Of Consuming Eggs On The Physical And Cognitive Development Of Food-Insecure Haitian Children, Monica Elaine Stewart

Graduate Theses and Dissertations

Within Latin America and the Caribbean, severe food insecurity is highest in Haiti. Fifty-five percent of the population lives below the poverty line with approximately 50% of the population undernourished. Given the typical diet in the developing world is primarily plant-based, the two studies presented in this thesis examine how eggs, a locally available animal protein, impact physical growth, cognitive development, and motor skills of food-insecure children from a single orphanage in Leogane, Haiti when added to the diet.

Characterization Of A Variant Of Tuberous Sclerosis Complex 2 And Its Interaction With Rheb, Sowmya Sivakumar

Graduate Theses and Dissertations

Protein-protein interactions are vital in maintaining proper function and homeostasis in cells. Some signaling pathways are regulated by G-proteins that work like switches to activate and deactivate pathways. Mutations in these proteins, their effectors or the interaction between proteins may cause dysregulation of signals that can lead to many diseases.

Rheb, Ras homology enriched in brain, is a Ras family GTPase that is vital in regulation of the mTOR (mammalian target of rapamycin) pathway that signals cell proliferation and growth. Due to the low intrinsic GTPase activity of Rheb, a GTPase activating protein (GAP), Tuberous Sclerosis Complex 2 (TSC2) down …

Mumbai Macbeth: Gender And Identity In Bollywood Adaptations, Rashmila Maiti

Graduate Theses and Dissertations

This project analyzes adaptation in the Hindi film industry and how the concepts of gender and identity have changed from the original text to the contemporary adaptation. The original texts include religious epics, Shakespeare’s plays, Bengali novels which were written pre-independence, and Hollywood films. This venture uses adaptation theory as well as postmodernist and postcolonial theories to examine how women and men are represented in the adaptations as well as how contemporary audience expectations help to create the identity of the characters in the films. Ultimately, this project hopes to fulfil the gap in scholarship on adaptations in Bollywood.

Factors Influencing Adoption Of Conservation Agriculture In The Democratic Republic Of The Congo, Willy Mulimbi Byamungu

Graduate Theses and Dissertations

The agricultural sector in the Democratic Republic of the Congo (DRC) is still struggling to cope with its post-independence political and structural instability. From 1961 to 2000, the DRC experienced a decrease of 34% and 37% in daily caloric intake and protein intake, respectively. The DRC’s agriculture sector, led by women (who are the core of subsistence farming), is now being targeted as a potential pathway out of poverty through sustainable development programs. Empowering farmers to increase productivity by educating them to use conservation agriculture (CA), a more sustainable alternative to the traditional slash-and-burn agricultural practice, could contribute to reducing …

The Energy Yield Of Global Crops 1961-2016, Quinn Montana

Graduate Theses and Dissertations

It is often suggested that world food production must increase by 70%-100% or more by the year 2050 if we are to feed the anticipated world population at that time. To evaluate this claim, global crop production from 1961 to 2016 was inventoried using publicly available data from the United Nations Food and Agriculture Organization (FAO). To determine the adequacy of global crop output for humanity, annual global food crop production data (T y-1) were converted to energy yield in kilojoules (KJ y-1). These data were then compared to the annual metabolic energy requirement of the global human population. The …

Impact Of The Implementation Of Class-Wide Function-Related Intervention Teams On Adolescent Student Behavior, Dana Renee Speight

Graduate Theses and Dissertations

Disproportionality in discipline has been well-documented in the research literature (Achilles, McLaughlin, & Croninger, 2007; Losen & Gillespie, 2012; Gregory, Skiba, & Mediratta, 2017; Skiba, Peterson, & Williams, 1997). Students from diverse ethnic backgrounds and students with disabilities are removed from their classrooms more frequently than their Caucasian peers without disabilities (Losen & Gillespie, 2012). This disparate removal of students from diverse ethnic backgrounds and students with disabilities has spurned education stakeholders to call for removal of punitive policies and replacement with positive behavior interventions and supports. This study sought to evaluate the impact of Class-Wide Function-related Intervention Teams (CW-FIT) …

Liquefaction-Induced Dragload And/Or Downdrag On Deep Foundations Within The New Madrid Seismic Zone, Ishimwe Elvis

Graduate Theses and Dissertations

Deep foundation elements are typically used to transfer structural loads for multi-story buildings and large-span bridges to a competent soil layer when 1) the soil close to the ground surface has no sufficient bearing capacity, and when 2) liquefiable soils are encountered. The majority of the bridges constructed within seismic zones rely upon the stability of earthen embankments and deep foundation that are installed above or within liquefiable soil deposits. Despite large factor of safety values or different load and resistance factors being used to adequately design deep foundations within seismic areas, soil liquefaction may cause extensive damage to the …

Interpersonal And Ideological Kindness: A Biocultural Approach, Sally Averitt-Hubbard

Graduate Theses and Dissertations

In accordance with Richard Dawkins’ materialist “selfish gene” theory of human behavior, altruism is a subject matter that is treated conservatively by biologists, whose understanding of the human version of altruism tends toward mutualistic and sometimes reputation-based explanations of charity, kindness, and helping. Trivers (1971) first stated that non-kin altruism could evolve if altruistic behavior is balanced between partners over time, implicating a strictly mutualistic domain for kindness. But kindness herein is defined, beyond mere mutualism or reciprocity, as “the quality of being friendly, generous, and considerate.” Further, kindness tends to have an action-oriented dimension, as in Goetz et al.’s …

Parameterizing And Aggregating Activation Functions In Deep Neural Networks, Luke Benjamin Godfrey

Graduate Theses and Dissertations

The nonlinear activation functions applied by each neuron in a neural network are essential for making neural networks powerful representational models. If these are omitted, even deep neural networks reduce to simple linear regression due to the fact that a linear combination of linear combinations is still a linear combination. In much of the existing literature on neural networks, just one or two activation functions are selected for the entire network, even though the use of heterogenous activation functions has been shown to produce superior results in some cases. Even less often employed are activation functions that can adapt their …

Applause, Laughter, Chants, And Cheers: An Analysis Of The Rhetorical Skill Of The “Great Communicator”, Reagan Gresham Dye

Graduate Theses and Dissertations

This study takes a content analytic approach to analyze the use of rhetorical devices in televised Republican National Convention (RNC) addresses by former U.S. President Ronald Reagan. By measuring rhetorical strategies and their relationship with the type, strength, synchrony, and duration of audience responses during the 1976, 1980, 1984, and 1992 RNCs, this study finds that Reagan had the ability to control speech factors to his advantage to promote positive audience response. This study finds that Reagan was adept at utilizing humor, external attacks, and advocating for his policy agenda in a way that elicited positive audience responses such as …

Evaluation Of Dicamba Off-Target Movement And Subsequent Effects On Soybean Offspring, Gordon Travis Jones

Graduate Theses and Dissertations

Commercial launch of cotton with resistance to dicamba, glyphosate, and glufosinate occurred in 2015 and launch of soybean with resistance to dicamba and glyphosate occurred in early 2016. It is likely that non-dicamba-resistant soybean will be planted in close proximity to dicamba-resistant soybean and cotton. Therefore, experiments were conducted to examine the distance dicamba moves during an application using commercial application equipment, as well as the effect the drift events have upon soybean offspring. Additional experiments were designed to investigate the effect glyphosate addition to dicamba has upon soybean growth and yield as well as possible effects on offspring. Lastly, …

The Role Of Co2 Sublimation In Mass Wasting And Landscape Evolution Under Martian Conditions, Matthew Edwin Sylvest

Graduate Theses and Dissertations

Here we present the first set of laboratory experiments under martian atmospheric conditions which demonstrate that the sublimation of CO2 ice from within the sediment body can trigger failure of unconsolidated, regolith slopes, and can measurably alter the landscape. Previous theoretical studies required CO2 slab ice for movements, but we find that only frost is required. Hence, sediment transport by CO2 sublimation could be more widely applicable (in space and time) on Mars than previously thought. This supports recent work suggesting CO2 sublimation could be responsible for recent modification in martian gullies.

A second set of experiments were carried out …

Pynchon And Place: A Geocritical Reading Of Thomas Pynchon, John Stout

Graduate Theses and Dissertations

A special emphasis on artificial or constructed spaces appears throughout Thomas Pynchon’s body of work. This thesis explores how Pynchon describes such spaces and their uses to address such weighty topics as social inequity and the struggle against authoritarianism. In examining the role of sheltering spaces in novels such as V. and Gravity’s Rainbow, I argue that Pynchon depicts various “outsider” characters as finding reification of their own forms of alterity within spaces either designed or co-opted with such purpose in mind. Through Pynchon’s depiction of spatial transformation in novels like Vineland and Inherent Vice, the author finds the opportunity …

Improving Asynchronous Advantage Actor Critic With A More Intelligent Exploration Strategy, James B. Holliday

Graduate Theses and Dissertations

We propose a simple and efficient modification to the Asynchronous Advantage Actor Critic (A3C)

algorithm that improves training. In 2016 Google’s DeepMind set a new standard for state-of-theart

reinforcement learning performance with the introduction of the A3C algorithm. The goal of

this research is to show that A3C can be improved by the use of a new novel exploration strategy we

call “Follow then Forage Exploration” (FFE). FFE forces the agents to follow the best known path

at the beginning of a training episode and then later in the episode the agent is forced to “forage”

and explores randomly. In …

A Proposed Approach To Hybrid Software-Hardware Application Design For Enhanced Application Performance, Alex Shipman

Graduate Theses and Dissertations

One important aspect of many commercial computer systems is their performance; therefore, system designers seek to improve the performance next-generation systems with respect to previous generations. This could mean improved computational performance, reduced power consumption leading to better battery life in mobile devices, smaller form factors, or improvements in many areas. In terms of increased system speed and computation performance, processor manufacturers have been able to increase the clock frequency of processors up to a point, but now it is more common to seek performance gains through increased parallelism (such as a processor having more processor cores on a single …
