Intrinsic Religiousness And Its Relation To Health Outcomes, Joseph Barnet
Intrinsic Religiousness And Its Relation To Health Outcomes, Joseph Barnet
Electronic Theses and Dissertations
Religiousness, broadly defined, has been shown to be predictive of a variety of health outcomes. Past literature surrounding religiousness research has utilized different definitions and measures for the meaning of religiousness. How religiousness is defined can influence its relationship in relation to health outcomes. The present study utilized a measure for intrinsic religiousness, which is defined as an internalization of the tenets of a particular faith. The present study examined whether intrinsic religiousness predicts problematic or illicit substance use or pornography use in a sample of participants that included mostly undergraduate students from the Appalachian region, as well as some …

Predicting Henry's Law Constants Of Volatile Organic Compounds Present In Bourbon Using Molecular Simulations., Christopher A Abney
Electronic Theses and Dissertations
Henry’s Law describes the partitioning of molecules into liquid and gas phases at low concentrations. Henry’s Law, which is based upon a species-dependent constant and the gas phase partial pressure, is useful for predicting phase behavior of dilute solutes. However, Henry’s Law constants are difficult to measure experimentally or to predict using structure-property or thermodynamic models. Herein, molecular simulations were used to calculate Henry’s Law constants for 18 volatile organic compounds (VOCs) present in bourbon. The novel simulations analyzed solvation thermodynamics of small organic molecules in 120 proof ethanol. A fast-growth non-equilibrium free energy method was used in which the …

Cfd Analysis Of Acoustofluidic Channels And The Effects On Biologic Delivery., Zachary T. Long
Electronic Theses and Dissertations
T-cell transformation is an ever-expanding treatment for several types of cancer, with a potential to be adapted to other disorders in which the immune system plays a key role in the pathophysiology. Currently, all FDA approved chimeric antigen receptor (CAR) T-cell cancer therapies rely on transformation via viral transduction. However, viral transduction is plagued by poor consistency and the potential to create adverse immune reactions when T-cells are reintroduced into a patient. Other transformation methods are being explored, with an alternative called acoustofluidic sonoporation showing promise. In these procedures, cells are passed through a channel, of the millimeter scale, while …
But Also Full Of Seeds For A Future That Could Have Turned Out Differently., Megan Marie Bickel
But Also Full Of Seeds For A Future That Could Have Turned Out Differently., Megan Marie Bickel
Electronic Theses and Dissertations
This thesis examines the relationship between "illusion," "allusion," and their relationship to contemporary images which announce, shield, or reference information. Beginning by discussing Casualist and Post-Digital Painting discourse, two styles I work within, we see connecting tissue in announcing and shielding of meaning. We look at the meaning of marks, and in the parallel exhibition, marks that utilize camouflage strategies appear as a metaphor for illuding to information which appears as conveying depth when there is none, and using paintings' symbols in objects that are not paintings. The work 'alludes' to what the viewer has seen before and relies on …
Prageru As A Parasite Public., Ryan A Corso-Gonzales
Prageru As A Parasite Public., Ryan A Corso-Gonzales
Electronic Theses and Dissertations
This thesis examines the media corporation PragerU as a parasite public, using the framework provided by Larson and McHendry (2019). Parasitic publics are “reactionary discursive spaces formed residual and institutionalized affectively through the invention, circulation and uptake of demagogic rhetorics” (Larson & McHendry, 2019, p. 517). The purpose of this thesis is to identify and analyze the argumentative tactics used by PragerU in the public sphere. I argue that PragerU utilizes its extensive network to resist counterpublicity and influence the dominant public sphere. This thesis demonstrates the ways in which this PragerU utilizes its unique position in the public sphere …

Adaptive Control And Parameter-Dependent Anti-Windup Compensation For Inertia Varying Quadcopters., Benjamin Edwards Farber
Adaptive Control And Parameter-Dependent Anti-Windup Compensation For Inertia Varying Quadcopters., Benjamin Edwards Farber
Electronic Theses and Dissertations
A novel parameter-dependent anti-windup compensator is developed to improve the performance of a saturation constrained model reference adaptive controller. The combined control structure solves the input saturation and stability problem for inertia varying quadcopters. The control synthesis follows the conventional two-step anti-windup design paradigm where a nominal controller is designed without consideration of the input saturation, and the anti-windup compensator is designed to minimize deviations from nominal performance caused by saturated inputs. To account for varying inertia of the quadcopter during package retrieval/delivery routines, the inertia parameters of the vehicle/package are estimated with an online recursive system identification technique, and …

Multi-Style Explainable Matrix Factorization Techniques For Recommender Systems., Olurotimi Nugbepo Seton
Electronic Theses and Dissertations
Black-box recommender system models are machine learning models that generate personalized recommendations without explaining how the recommendations were generated to the user or giving them a way to correct wrong assumptions made about them by the model. However, compared to white-box models, which are transparent and scrutable, black-box models are generally more accurate. Recent research has shown that accuracy alone is not sufficient for user satisfaction. One such black-box model is Matrix Factorization, a State of the Art recommendation technique that is widely used due to its ability to deal with sparse data sets and to produce accurate recommendations. Recent …

Photoassisted Synthesis Of Complex Polyheterocycles Via Rational Design Of Tailored Photoprecursors, Tina Alanna Holt
Electronic Theses and Dissertations
Natural products remain the most common source for drug leads, although diversity-oriented synthesis of unnatural complex molecules is gaining momentum. Our lab has been developing experimentally simple and straightforward approaches to complex molecular architectures via photochemical reactions involving a minimal number of experimental steps. In order to achieve this, photoprecursors were assembled via high yielding reactions. Next, we deployed photoinduced cycloadditions to create complex 3-dimentional structures. Lastly, with this obtained primary photoproduct, post-photochemical transformations were used to further grow its scaffold complexity.
One method to increase scaffold complexity is the [4+2] intramolecular cycloadditions of azaxylylenes, which are developed through standard …
Moving Past ‘One Size Fits All’: Developing A Trajectory Deviance Index For Dynamic Measurement Modeling, Yixiao Dong
Moving Past ‘One Size Fits All’: Developing A Trajectory Deviance Index For Dynamic Measurement Modeling, Yixiao Dong
Electronic Theses and Dissertations
Dynamic Measurement Modeling (DMM) is a recently developed measurement framework for gauging developing constructs (e.g., learning capacity) that conventional single-timepoint tests cannot assess. Like most measurement models, overall model fit indices of DMM do not indicate the measurement appropriateness for each included student. For this reason, other measurement modeling paradigms (e.g., Item-Response Theory; IRT) utilize person-fit or model appropriateness statistics to indicate whether a measurement model appropriately describes the data from each individual student. However, within the extant DMM framework, no statistical index has yet been developed for this purpose. Thus, the current project advanced a person-specific DMM Trajectory Deviance …
