Untangling The Reciprocal Relation Of The Behavioral And Physiological Immune Systems, Baris Sevi

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the past decade, there has been an exponential increase in the study of the Behavioral Immune System (BIS), a suite of psychological processes that serves an infectious disease avoidance function. The BIS is proposed to be inherently intertwined with the physiological immune system. However, very few studies have actually demonstrated this fundamental, theoretical assumption. The purpose of this thesis was to test the possible relation between the physiological and behavioral immune systems in two studies. In Study 1 (N = 388), the relation between implied activation of the physiological immune system and BIS sensitivity was examined. Participants who reported …

A Video Decision Aid To Influence Advance Care Planning, Angela Petry

Graduate Theses, Dissertations, and Problem Reports (ETD)

The best mechanism to achieve successful advance care planning has yet to be identified. A randomized, controlled, experimental study was performed with a sample of 54 men and women who met inclusion criteria and were randomized into the intervention versus the control group in an outpatient clinical setting in rural West Virginia (WV) from December 2018 to March 2019. Participant mean age was 72.4 years. For those who chose to participate (n=42), the intervention group received the usual standard of care, which was a face to face advance care planning (ACP) discussion with the new intervention of a video decision …

Aspect Influence On Productivity When Applying The Deferment Harvest Method In Mixed-Oak Hardwood Forests In West Virginia, Breanne Held

Graduate Theses, Dissertations, and Problem Reports (ETD)

The deferment harvest method is a new forest management treatment in central Appalachian hardwood forests. It is intended to primarily improve aesthetics by leaving select residual trees in the forest stand beyond the establishment of the regeneration cohort. However, there are concerns with residual tree quality due to the development of epicormic branches and if the presence of forest canopy influences the species composition and development of the regeneration. Topographic aspect can influence differences in productivity in both the residual and regeneration cohorts. This study examined if residual tree quality for timber value and a desirable species composition of the …

Character Morality, Enjoyment, And Appreciation: A Replication Of Eden, Daalmans, And Johnson (2017), Koji Yoshimura

Graduate Theses, Dissertations, and Problem Reports (ETD)

Much research on media entertainment seeks to explain why viewers enjoy and appreciate a variety of media content. Affective disposition theory suggests that media enjoyment results from perceptions of the morality of characters and viewers’ expectations for characters’ narrative outcomes. However, research has struggled to explain how characters with varying morality (i.e., not perfectly good or bad) entertain viewers. This study replicates a previous study conducted by Eden, Daalmans, and Johnson (2017) that investigated different types of morally ambiguous characters, using a typology of character types based on an online, collaboratively sourced typology.

Like the original study, this study found …

Petrophysical And Geomechanical Characterization Of The Marcellus Shale In The Appalachian Basin, Yixuan Zhu

Graduate Theses, Dissertations, and Problem Reports (ETD)

In recent years, more and more attention is paid to shale gas and hydrocarbon liquids exploration and exploitation in unconventional reservoirs. With the development of horizontal drilling and hydraulic fracturing, production from unconventional reservoirs has been greatly increased. However, not all wells, regions and basins harbor highly successful shale gas and liquids producers. In order to improve the production efficiency and reduce the cost of projects, detailed analysis needs to be undertaken to characterize the reservoir. As opposed to conventional reservoirs, extraction of gas in the unconventional reservoir is dependent not only on the reservoir quality, but also on completion …

Choose Your Own Lecture: Students’ Motivational Resources As A Consequence Of Autonomy-Supportive Instruction, James P. Baker

Graduate Theses, Dissertations, and Problem Reports (ETD)

The purpose of this dissertation was to extend the self-determination theory literature by investigating the utility of the choose your own lecture method of instruction. This method of instruction allows students to control the direction of a lesson. In line with the theoretical propositions of SDT, the researcher hypothesized that this style of teaching would support students’ inner motivational resources (i.e., autonomy-need satisfaction and intrinsic motivation) and in turn, foster students’ interest in the topic of the lesson, free-choice persistence, cognitive learning, affect for the course, and expressive dissent. A 50-minute live-lecture experiment on environmental communication (climate change, risk communication, …

Glial Cell Expansion And Intercellular Signaling In The Developing Medial Nucleus Of The Trapezoid Body (Mntb), Ashley N. Brandebura

Graduate Theses, Dissertations, and Problem Reports (ETD)

Neural circuit formation is a complex process involving coordinated communication between neurons, glia and vascular-associated cells (VACs). Each cell type is responsible for a unique transcriptional and translational contribution to tissue maturation. Deciphering the intercellular signaling patterns which guide neural circuit formation during normal development is thus an essential step in understanding which components of neural circuit formation go awry in neurodevelopmental disorders. The medial nucleus of the trapezoid body (MNTB), located in the auditory brainstem, was used as a model system to study the dynamics of neural circuit formation because it contains a mostly homogeneous population of postsynaptic neurons …

Factors Influencing Survival, Productivity, And Population Growth Of Eastern Wild Turkeys In Northeastern South Dakota, Reina M. Tyl

Graduate Theses, Dissertations, and Problem Reports (ETD)

The population of eastern wild turkeys in northeastern South Dakota appeared to be expanding soon after reintroduction in the 1990s, however, recent harvest trends suggest declining abundance in the region. Spring turkey hunting expenditures are projected to be around $6.5 million in South Dakota, with about $3 million of those expenditures occurring within the northeastern prairie region. However, the number of birds harvested during the spring prairie firearm season has been declining since 2010. Due to concerns about a declining population, the autumn hunting season was closed in 2014. The cause of the apparent decline is unclear. Updated demographic information …

Using Lidar To Approximate Keystone Structure And Evaluate Management Practices In Potential Habitats Of The Endangered Karner Blue Butterfly (Lycaeides Melissa Samuelis), Brandyn Balch

Graduate Theses, Dissertations, and Problem Reports (ETD)

Keystone structure is the spatial structure required by a given species, at a scale that is determined by that species’ needs and mobility. The endangered Karner blue butterfly (Lycaeides melissa samuelis, hereafter KBB) has a keystone structure that incorporates trees and bushes to provide the mixture of sun and shade required to fulfil its life functions. Airborne light detection and ranging (lidar) is a potentially invaluable tool for characterizing keystone structures. However, lidar has yet to be utilized to evaluate structural suitability of KBB habitats. Therefore, I investigated the use of lidar for characterizing critical attributes of KBB habitat structure, …

Resurgence Of Academic Responses, Catherine Louise Stephens

Graduate Theses, Dissertations, and Problem Reports (ETD)

Resurgence is the recurrence of a previously reinforced response after a more recently reinforced response is placed on extinction. Resurgence may explain the recurrence of socially appropriate behavior, including academic responding, but this had not yet been empirically demonstrated. The aim of this study was to determine if resurgence would occur when a participant solved quadratic equations using multiple methods. Each participant was taught two methods of solving quadratic equations across experimental phases, followed by a phase in which neither method resulted in the correct solution. In the first phase, only simple factoring was reinforced. In the second phase, only …

Johannes Brahms’S Fünf Ophelia-Lieder Performance History, Cultural Context, And Character Study As It Pertains To Johannes Brahms’S Fünf Ophelia-Lieder: A Performer’S Perspective, Caryn Alexis Crozier

Graduate Theses, Dissertations, and Problem Reports (ETD)

This document aims to contribute research on the lesser known and under researched vocal works by Johannes Brahms, particularly his Fünf Ophelia Lieder. This song cycle, while not written to be performed on its own, originally, is a rich technical resource for beginning singers and advanced singers alike. Brahms wrote a simple melody with sparse accompaniment that really allows the performer to focus on language, technique, or dramatic interpretation. This document looks at Brahms’s setting of Ophelia’s mad scene through many different lenses including theoretical, by analyzing each song musically and dramatically, historical analysis of Hamlet and its many iterations, …

Development Of A Sustainability Evaluation And Control Framework For Chemical Processes, Shuyun Li

Graduate Theses, Dissertations, and Problem Reports (ETD)

Industry, government, and society have begun to shift from economic stand-alone focus to the inclusion of sustainability in the decision-making process. This shift can be attributed to the growing environmental and social awareness that makes consumers and stakeholders not only care about product quality and cost, but also products and processes that minimize the environmental impact and conserve natural resources. As a result, some progress has been made in recognizing and understanding the challenges of sustainable development, which helps evaluating the sustainability performance of a specific process/product. In particular, sustainability assessment tools and methodologies have been developed to help the …

Low-Power Reconfigurable Sensing Circuitry For The Internet-Of-Things Paradigm, Alexander Dilello

Graduate Theses, Dissertations, and Problem Reports (ETD)

With ubiquitous wireless communication via Wi-Fi and nascent 5th Generation mobile communications, more devices -- both smart and traditionally "dumb" -- will be interconnected than ever before. This burgeoning trend is referred to as the Internet-of-Things. These new sensing opportunities place a larger burden on the underlying circuitry that must operate on finite battery power and/or within energy-constrained environments. New developments of low-power reconfigurable analog sensing platforms like field-programmable analog arrays (FPAAs) present an attractive sensing solution by processing data in the analog domain while staying flexible in design. This work addresses some of the contemporary challenges of low-power wireless …

Metal Nanomaterials: Immune Effects And Implications Of Physicochemical Properties On Sensitization, Elicitation, And Augmentation Of Allergic Disease, Katherine Adair Roach

Graduate Theses, Dissertations, and Problem Reports (ETD)

Many allergenic metals are being manufactured in nanoparticulate forms. Although the decreased size profile of metal nanomaterials has been consistently associated with more pronounced lung toxicity compared to larger materials, it is unclear if metal-induced immunotoxic effects exhibit a similar size-dependency.

The central hypothesis of these studies was that metal nanoparticles cause more pronounced immunomodulatory effects on allergic processes than larger forms of respective metals. Moreover, it was anticipated that, similar to their inflammatory potential in airways, the magnitude of these responses would correlate best with the dose metric of surface area.

The first set of studies utilized fine and …

Discrimination And Behavioral Responses To Communication Signals Compared Across Apteronotids., Danielle Leigh Dillon-Seeger

Graduate Theses, Dissertations, and Problem Reports (ETD)

Sensory systems are often uniquely tailored to encode behaviorally relevant signals and comparative studies across species can thus reveal how evolutionary changes shape sensory functions. The structure of communication signals varies widely between ghost knifefish species. Recent findings suggest that the nervous system co-adapted to the various signal structures observed across species to support different sensory behaviors. The aim for this thesis was to compare the sensory behavior of 3 species of ghost knifefish to contrast their behavioral performance with the known differences in neurophysiology. We hypothesize that for the different signal types and species, the ability to discriminate small …

Graduate Theses, Dissertations, and Problem Reports (ETD)

Based on unexpected results in her previous research, Dr. Frances Van Scoy became inspired to develop a tool that allows the user to navigate spaces using auditory instead of visual cues to detect objects or anomalies in a given space in an effort to overcome the encountered obstacles. This problem report details the work of one of her grad students in exploring different open source software for developing the tool as well as research into gestures and other considerations when furthering this research into the third dimension at a future date.

Canonical Wnt Mechanisms In Neural Crest Induction, Mark Stephen Perfetto

Graduate Theses, Dissertations, and Problem Reports (ETD)

Canonical Wnt signaling is a pathway that is critical for normal development and the progression of disease. The canonical Wnt signaling pathway was put together carefully by synthesizing decades of research. Over those decades, canonical Wnt signaling was found to be crucial for nearly all aspects of development, but of importance to this thesis, is a key regulatory factor for the development of the highly migratory multipotent stem cells, the neural crest. As our knowledge of the importance of canonical Wnt signaling grew, research is being conducted to further our understanding of how canonical Wnt signaling communicates with other signaling …

Tie Strength, Optimal Connections, And Distance In Social Networks, David Anthony Buch

Graduate Theses, Dissertations, and Problem Reports (ETD)

Social network analysis seeks to understand the structure of relationships in networks of actors. As researchers identify structural properties of interest (e.g. vulnerability to network cuts) they introduce measures to quantify the expression of those properties in observed networks. In fact, it is not uncommon that multiple measures are introduced purporting to evaluate a single property. Relative merits of competing measures are not self-evident but the corresponding inferences can conflict, encouraging arbitrary choice among measures and endangering the validity of conclusions. We argue (i) that multiplicity of measures is a necessary consequence of the de rigueur practice of conflating different …

Dynamic Discrepancy Reduced Order Modeling For Fischer-Tropsch Synthesis Over Cobalt-Based Catalyst, Jose Miguel Bohorquez

Graduate Theses, Dissertations, and Problem Reports (ETD)

Advances in carbon capture techniques and demands in alternative fuel sources have increased over the past couple of decades. The Fischer-Tropsch Synthesis (FTS) provides a viable way to produce hydrocarbons from natural gas, coal, CO₂, or biomass. However, current comprehensive models for FTS encompass large number of reacting species, readsorption and conversion of primary products, surface intermediates, and coverage-dependent reaction rates. To accurately predict the products obtained through the process a reduced order model has been developed. By reducing the number of parameters of an existing comprehensive model, uncertainty is introduced. The uncertainty can be quantified by using …

An Empirical Analysis Of An Algorithm For The Budgeted Maximum Vertex Cover Problem In Trees, Mujidat Abisola Adeyemo

Graduate Theses, Dissertations, and Problem Reports (ETD)

Covering problems are commonly studied in fields such as mathematics, computer science, and engineering. They are also applicable in the real world, e.g., given a city, can we build base-stations such that there is network availability everywhere in the city. However, in the real world, there are usually constraints such as cost and resources. The Budgeted Maximum Vertex Cover is a generalization of covering problems. It models situations with constraints. In this thesis, we empirically analyze an algorithm for the problem of finding the Budgeted Maximum Vertex Cover in undirected trees (BMVCT). The BMVCT problem is defined as follows: Given …

The purpose of this research document is to examine elements of musical hybridity and cultural influences in renowned African-American flutist-composer Valerie Coleman’s Wish Sonatine and Fanmi Imèn for solo flute and piano. Prominently known for her chamber music works, Coleman describes her compositional style as “urban-classical,” which infuses elements of popular American styles into modern Western art music traditions to highlight and encapsulate the cultural experiences of various diasporas of our time.

The most significant elements of hybridity and cultural influences examined in Wish Sonatine and Fanmi Imèn are programmatic imagery and compositional motifs. The programmatic imagery is represented through …

Artificial Immune System For Unmanned Aerial Vehicle Abnormal Condition Detection And Identification, Ryan G. Mclaughlin

Graduate Theses, Dissertations, and Problem Reports (ETD)

A detection and identification scheme for abnormal conditions was developed for an unmanned aerial vehicle (UAV) based on the artificial immune system (AIS) paradigm. This technique involves establishing a body of data to represent normal conditions referred to as “self” and differentiating these conditions from abnormal conditions, referred to as “non-self”. Data collected from simulation of the UAV attempting to autonomously fly a pre-decided trajectory were used to develop and test a scheme that was able to detect and identify aircraft sensor and actuator faults. These faults included aerodynamic control surface locks and damages and angular rate sensor biases. The …

Music Technology, Gender, And Sexuality: Case Studies Of Women And Queer Electroacoustic Music Composers, Justin Thomas Massey

Graduate Theses, Dissertations, and Problem Reports (ETD)

This document aims to contribute to the established scholarship that highlights the role gender and sexuality has with one’s fundamental relationship to composition and music technology. The profession of electronic music composition and music production are strongly associated with notions of power and control, as much of this technology was built during the World Wars and Cold War. These aggressive views have created gendered language and metaphors in the field. Metaphors are the primary way in which we accommodate and assimilate information and experience to our conceptual organization of the world. It is at the source of our capacity to …

Population Health Of Spotted Salamanders (Ambystoma Maculatum) In Created Vernal Pools: An Integrative Approach, Alice R. Millikin

Graduate Theses, Dissertations, and Problem Reports (ETD)

Habitat creation is an important tool for conservation to counteract habitat loss and degradation. Vernal pools are susceptible to destruction due to limited detection, protection, and regulation. These wetlands provide fishless breeding habitat for many amphibian species including spotted salamanders (Ambystoma maculatum) in eastern North America. Determining whether created vernal pool habitat is successful is often determined by demographic data of colonizing populations. I suggest that hormone levels, population genetics, and disease prevalence can improve our understanding of population health in created habitat. The goal of this dissertation was to assess the health of spotted salamander larvae in …

X-Ray Fluorescence Applications In Mudrock Characterization: Investigations Into Middle Devonian Stratigraphy, Appalachian Basin, Usa, Keithan Garrett Martin

Graduate Theses, Dissertations, and Problem Reports (ETD)

Mudrocks are characterized by nanometer-scale pore sizes and nano-darcy permeability, which plays a significant role in hydrocarbon flow during production. Resulting from these characteristics, mudrocks were exclusively considered a source rock, which charged overlying, more porous mediums. Hydraulic fracturing, a technology used to create artificial fractures to liberate hydrocarbons from the reservoir, enabled natural gas to be produced from mudrock reservoirs economically. Over the last fifteen years, this technology motivated research efforts to understand reservoir characteristics of mudrock. These investigations significantly improved our knowledge of mudrock systems, but have also highlighted key areas that are undeveloped and/or where conflicting hypotheses …

Behavioral Impairment Following Gestational Exposure To Titanium Dioxide Nanomaterial Aerosols In Male And Female Rats, Matthew Leland Eckard

Graduate Theses, Dissertations, and Problem Reports (ETD)

Engineered nanomaterials (ENMs) are beginning to be recognized as hazardous to human and animal health. Titanium dioxide (TiO2) is primarily used as a whitening agent in paints, plastics, and sunscreens. While relatively inert in its bulk form, nano-TiO2 (diameter) can produce prolonged inflammation and oxidative stress in target tissue. Recently, the potential for nano-TiO2 to cause neuroinflammation and damage has heightened concerns about its continued use. One important concern is that nano-TiO2, and other metal oxide ENMs, may affect fetal neurodevelopment. Accordingly, it is imperative to screen ENMs, like TiO2, for possible neurotoxicity following developmental exposures. The current set of …

Roadnet: Robust Adaptive Network For Information Diffusion In Vanet, Priyashraba Misra

Graduate Theses, Dissertations, and Problem Reports (ETD)

The automotive industry has changed more in the last one decade than ever before. Rapid advancements in autonomous driving have opened up opportunities for CAVs (Connected and Automated Vehicles). Vehicles today rely on a sensor-suite to map the surrounding and use that information for safety and navigation. The sensor's view is limited to its line of sight and this drawback can be tapered off by using Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I), generally referred to as Vehicle to Everything (V2X) communication. In this thesis, we specifically focus on utilizing V2V communication using on-board Dedicated Short Range Communication …
