Computational And Experimental Modeling Of Particle Transport Inside Respiratory Pathways And Indoor Environments, Abir Malakar

Electronic Theses and Dissertations

This thesis aims to explore efficient drug delivery to clinical target sites along the human upper airway that strongly depends on variables associated with the delivery device and the drug formulation, e.g., the device plume angle, particle sizes of drug solution, drug delivery speed of the device, viscosity of the drug solution, delivery axis orientation, and the formulation density. In our investigation, we prioritize the nasopharynx, the primary site of initial viral infection, as the ideal target zone for drug delivery. We have used Large Eddy Simulation and Lagrangian techniques to replicate breathing at 15 L/min and quantify regional drug …

I Can't Look Away: Parasocial Relationships With Dance Mom Characters Across Tv And Social Media, Kennedy Kay Pirlet

Electronic Theses and Dissertations

In 2019, Dance Moms ended its airing on Lifetime at the completion of the eighth season. However, the show and its cast members remained popular on social media platforms like TikTok, but we still didn’t know the relationship between watching the show and following cast members on multiple social media platforms or who audiences were closest to. To answer this question, the celebrity-persona parasocial interaction scale and experience of parasocial interaction scale were utilized. These scales were used in this study and found reliable. Snowball recruitment focusing on social media platforms and emails yielded 180 eligible sample participants. Through a …

Portable X-Ray Fluorescence Spectrometry For Sensing Salinity And Sodicity In Glacial Northern Great Plains Soils With Machine Learning Models, Adam Devlin

Electronic Theses and Dissertations

Saline and sodic soils are an increasing concern across the Northern Great Plains (NGP) due to factors of climate change and land management that are drawing geologically derived salts to the land surface. Traditional laboratory assessments, such as electrical conductivity (EC) and sodium adsorption ratio (SAR), are time and resource consumptive. Portable X-ray fluorescence (PXRF) may be a viable proximal sensing alternative, as it is able to provide elemental data in minutes, in situ or ex situ, and can directly quantify salinity-associated elements like Ca, Mg, and S. PXRF paired with predictive models has proven useful for a range of …

Organizational Culture's Impact On Job Satisfaction: A Reconceptualization Of The Competing Values Framework, Isaac Thor Erickson

Electronic Theses and Dissertations

Academic job satisfaction has been decreasing in the U.S. which has profound negative impacts such as burnout and decreased well-being of employees. One way that job satisfaction can be increased is through understanding and changing organizational cultures through better communication. The Competing Values Framework (CVF; Quinn & Rohrbaugh, 1983; Belasen & Frank, 2010; Lund, 2003) has been used to understand how organizational cultures and their communicative norms relate to job satisfaction. However, the CVF relies on categorical measures sitting on two axes that are not orthogonal. As such, the study posits breaking these two axes into four dimensions of organizational …

The Spatial Ecology Of Plains Spotted Skunks In South Dakota: Insights From Species Distribution, Resource Selection, And Co-Occurrence Models, Kara M. White

Electronic Theses and Dissertations

The plains spotted skunk (Spilogale interrupta) is a data-deficient small carnivore native to the central plains of North America that has experienced significant population declines. My dissertation investigates the species’ distribution, habitat associations, and interspecific interactions in South Dakota, providing crucial information for conservation actions. In Chapter 1, I developed ensemble distribution models on a broad scale, incorporating species location data from 1985–2020, environmental factors, and six predictive modeling algorithms. I identified key predictors including mean temperature diurnal range and proportion of area as pasture, and estimated ~31,300 km2 of potential habitat, predominately in eastern South Dakota. In Chapter 2, …

Advancing Karl Jaspers: The Connection Between The Theory Of Existential Communication And Mentoring Satisfaction, Nolan Patrick Bowers

Electronic Theses and Dissertations

Existential philosopher Karl Jaspers’s theory (1932/1970; 1935/1971b) of existential communication is understood to be his most important contribution to existentialism. Additionally, this theory has unique ties to the phenomena of communication, begging its use as a dialogic theory. However, Jaspers’s theory has been relatively untouched by academia. This thesis understands the theory of existential communication through an operationalization of its aspects and explicitly connecting them to communicative behaviors. These aspects of existential communication are (1) vulnerability, (2) open-mindedness, and (3) equality. This study set out to determine whether these aspects could be found within mentoring relationships and support the aspects …

An Investigation Of Bidder Behaviour In Wic Infant Formula Rebate Auctions, Ashma Pandey

Electronic Theses and Dissertations

This research investigated the competitive bidding dynamics for infant formula rebate contracts within the Special Supplemental Nutrition Assistance Program for Women, Infants, and Children (WIC). I begin by focusing on the differences between winning and losing bids. The study employs multiple regression to predict rebate bids submitted by major manufacturers when they win a contract. I next conduct a paired t-test for each manufacturer – revealing statistically significant differences between predicted bids (based on the parameters from the winning model) and actual bids when a manufacturer did not win. This suggests that each manufacturer bids significantly lower rebates (higher net …

Soil Responses To Eastern Redcedar (Juniperus Virginiana L.) Afforestation And Prescribed Fire In South-Central South Dakota, Robert Schaefer

Electronic Theses and Dissertations

Research was conducted in 2019 and 2020 on rangelands located in south-central South Dakota assessing a number of physical, chemical, and biological properties of mineral ustepts and ustents soils associated with eastern redcedar (ERC) (Juniperus virginiana) afforestation and prescribed fire. ERC afforestation appeared to be associated with significantly higher field-condition soil aggregate stability, cation exchange capacity (CEC), soil pH, and fungi:bacteria (F:B) as well as significantly lower soil moisture, nitrate-N, phosphorus, bacteria biomass, and Gram-positive:Gram-negative (GP:GN) bacteria compared to native grassland conditions, while other mineral soil properties appeared relatively unaffected. Compared to soil conditions under dense, living ERC canopies, prescribed …

Increasing Retention Of Women In Hunting And Fishing, Shelby Isensee

Electronic Theses and Dissertations

Despite national declines in hunting and fishing, women are making inroads in historically male-dominated sports. To further encourage women’s participation, states established programs to recruit, retain, and reactivate [R3] hunters and anglers. Women are participating in these programs and other recreational groups to access opportunities to learn skills and grow their networks. Yet, very little is known about what programs are offered for women, what aspects of programs are most effective to support women’s retention in these activities, and what women’s hunting and fishing groups are available across the landscape. To address these questions, I collected qualitative data from participant …

Methods For Optimizing Detection And Evaluating Habitat Use Of North American River Otters In South Dakota, Jessica Speiser

Electronic Theses and Dissertations

North American river otters (Lontra canadensis) play a critical role as an apex predator in riverine ecosystems. A challenging species to survey using traditional methods, they remain understudied in non-forested regions, such as the Northern Great Plains, where habitat degradation and landscape fragmentation may reduce habitat quality and availability and disrupt landscape connectivity. This thesis aims to improve detectability and investigates the habitat use of river otters in South Dakota to better understand habitat needs of otters and improve their continued recovery and management. My first chapter provides a brief overview of river otters and their ecological roles in freshwater …

Isolation, Molecular Characterization, And Epidemiological Analysis Of An Emerging Avian Metapneumovirus Subgroup B In Us Poultry, Sumit Jangra

Electronic Theses and Dissertations

Avian metapneumovirus (aMPV) is one the most economically important poultry respiratory pathogens belonging to the family Pneumoviridae and genus Metapneumovirus, which can affect both domestic and wild birds. aMPVs are classified into four subgroups (A, B, C, and D) based on the level of genetic variations and antigenic differences. aMPV causes turkey rhinotracheitis (TRT) and swollen head syndrome (SHS) in turkeys and chickens respectively. Recently, outbreaks of respiratory disease in meat-type birds and a significant decline in egg production with respiratory signs in breeders were reported from different states in the USA. Isolating aMPV is challenging as it is a …

Comparative Lineament And Geomorphic Analysis Of Chaotic Terrains And Noctis Labyrinthus, Mars, Sarah A. Walton

Electronic Theses and Dissertations

Noctis Labyrinthus (NL) is an extensional trough network connecting the Tharsis rise and Valles Marineris on Mars. Chaotic terrains are a group of polygonally-fractured surface features commonly associated with subsidence due to rapid fluid loss within the subsurface. Polygonal surface patterns are seen at both sites, where geometric topographic highs are bounded by low troughs. Lineaments, topography, and geomorphology of NL and chaotic terrains were analyzed to determine tectonics and fluid influence in the formation and evolution of both sites. NL shows preferential fracture patterns associated with regional extension. Lineaments within chaotic terrains do not show cumulative preferential trends but …

Using A Three-Dimensional Theoretical Orientation Matching Model To Predict Therapeutic Outcomes, Daniel Rhodes

Electronic Theses and Dissertations

Matching helpers and clients in a therapeutic setting is inefficient and ineffective. So far, there are no significant and enduring variables that reliably match helpers and clients that lead to positive therapeutic outcomes. This study attempts to match helper and client using theoretical orientation. It uses a quantitative methodology to predict therapeutic outcomes given match quality in the therapeutic dyad. Participants were 30 dyadic pairs—consisting of one helper and one client—who had a pre-existing therapeutic relationship. Each was given an assessment tool, used to measure their theoretical orientation to psychotherapy. Results showed no statistically significant relationships between theoretical orientation match …

Negative Psychology Of Anti-Semitism: Fear Of The Uncategorizable, Benjamin Strosberg

Electronic Theses and Dissertations

Anti-Semitism is a pervasive global issue, particularly prominent in the United States. Studying and defining anti-Semitism prove remarkably challenging for scholars, leading to inadequate understanding and exclusion from contemporary academic discourse and social justice initiatives. In this dissertation, I made the case that anti-Semitism is hard to categorize, stemming, in part, from the difficulty in categorizing what it is to be Jewish, which seems to be multi-form (a figure of thought, a race, an ethnicity, a religion, a nation, none of the above). In thinking about the difficulty in categorization, I constellated various instances of anti-Jewish practices across historical epochs …

Understanding Unacceptable Graduation Outcomes For Historically Excluded Trio Student Support Services Students, Erica Willis

Electronic Theses and Dissertations

The primary purpose of this mixed-methods study is to define the problem and to understand the system that has been leading to unacceptably low graduation outcomes for historically excluded Trio Student Support Services (Trio SSS) students at Mid-Atlantic University (MAU), a pseudonym. To achieve the primary purpose extant documents and institutional data that can shed light on system processes and institutional conditions that perpetuate disparities in graduation outcomes, particularly for historically excluded racial groups that exist at the intersection of first-generation status and/or low socioeconomic status, will be analyzed. The secondary purpose of this study is to identify potential change …

A Demonstration Of Enactivist Personality Assessment Using The Five-Factor Model, Garri Hovhannisyan

Electronic Theses and Dissertations

This dissertation seeks to extend the intellectual and existential horizon of the enactive approach by bringing forth an enactivist understanding of human cognitive life as it is lived from the perspective of personality traits. The theoretical task of this dissertation is to review existing evidence in support of the Enactivist Big-5 Theory (EB5T) of personality and its potential for bridging the phenomenological gap between minimal and human cognition. As a phenomenologically grounded theory of personality, EB5T conceptualizes individual differences not merely as differences in trait measures within a person but as differences in styles of how individuals bring forth, experience, …

Comparative Functional And Genomic Analysis Of Protein Targets Of Sexual Selection In Primates, Brianna Ports

Electronic Theses and Dissertations

Sexual selection is driven by the differential reproductive success of individuals, which is influenced by competition for mates and mate choice. In primates, this selective pressure has been attributed to the development of distinct anatomical, physiological, and behavioral characteristics. By employing comparative functional and genomic methodologies, this study aimed to assess the repercussions of primate sexual selection. To better understand the mechanisms driving sexually selected traits, an unbiased genome-wide analysis was used to associate rates of protein evolution with relative testes size and sexual size dimorphism. While previous research focused on the rapid evolution of male reproductive proteins in response …

Role Of The Anti-Viral Immune Response In Neural Cell Modulation And Neurological Sequelae Of Childhood Viral Infections, Yashika Kamte

Electronic Theses and Dissertations

Viral infections of the central nervous system (CNS) often result in neurological sequelae and are considered a risk factor for the development of neurological disease. Moreover, the outcomes of a viral infection are largely dependent on the age of the host, with younger hosts developing more profound neuropathology. Perhaps the developing brain coupled with an immature immune system contributes to worse outcomes in the very young. Children suffering from brain infections are more prone to develop enduring neurological impairments even after recovery from the infection. Although majority of the brain growth occurs in utero, neurodevelopment continues throughout the juvenile …

Inclusive Education For All: Identifying Teacher Beliefs About Working With Students With Disabilities, Chelsea Sharek

Electronic Theses and Dissertations

The purpose of this study was to investigate the beliefs K-12 teachers have when working with students with disabilities in a rural Pennsylvania school district. This study aimed to identify if teachers’ personal beliefs created biases about their students and school systems; thus, forming barriers and preventing an inclusive education when working with disabled students. Instrumentation for this quantitative study is the Multidimensional Attitudes Towards Inclusive Education Scale (MATIES) survey. Findings suggest that some teachers at Sunnyside School District (pseudonym) hold personal beliefs that could create biases about their students and school system that may form barriers when working with …

The Contribution Of Principlism To Foster Ethical And Clinical Reciprocity In Resolving Healthcare Dilemmas, Dominic Glorioso

Electronic Theses and Dissertations

Principlism is an ethical method that uses an analytical framework based on a set of principles that can function as guidelines for healthcare professionals. The term was made

famous by the work of two bioethicists, Tom L. Beauchamp and James F. Childress. Their book, Principles of Biomedical Ethics and its multiple editions described a set of norms that are basic

for biomedical ethics. The first edition of their book was published in 1979, and the ninth edition in 2019. Its persistence and durability speak for themselves. In addition, their writings made

famous the four bioethical principles of respect for Autonomy, …

The Normative Requirement For Shared Decision Making (Sdm) In Healthcare Ethics, Margaret Nornor-Quadjie

Electronic Theses and Dissertations

Medicine and medical technology started to advance after World War II. During that period, the practice of medicine became technical. A lot began to happen in the biomedical world during the period after WWII that attracted comments, criticisms, and analyses from scholars. Perhaps, the 1947 Doctors’ Trial at the Nuremberg Tribunal and the Nuremberg Code may be said to be the defining moment for bioethics. These events eventually led to, in the United States, the passage of the National Research Act of 1974 that established the Institutional Review Board system and the National Commission for Protection of Human Subjects of …

Functional Cynicism, Michelle Fried

Electronic Theses and Dissertations

Trait cynicism, or “cynical hostility” as measured by the Minnesota Multiphasic Personality Inventory’s Cook-Medley Scale, is defined and studied as characteristics associated with psychopathology, interpersonal conflict, and negative health outcomes including heart disease and cognitive decline. Likewise, “organizational cynicism” is operationalized in industrial/organizational psychology for the purpose of describing and identifying an undesirable employee type in the workplace. This research proposes an alternative assessment. It reconnects cynicism with its roots in ancient philosophy by asking if cynical attitudes, despite their negative valence ascribed in the modern literature and conventional opinion, may serve a practical purpose. This study of Functional Cynicism …

Understanding The Psychological Significance Of Astrology In Millennial Women's Lives, Rachel June Floyd

Electronic Theses and Dissertations

In North America, astrology has been experiencing a resurgence in popularity. This is immediately remarkable given that the United States and Canada are industrialized, modern societies where astrology is widely lamented as a pseudoscience. This dissertation presents a phenomenological exploration of the underlying reasons for this cultural trend, particularly among the demographic that uses it most: millennial women. Existing psychological literature on astrology is primarily dominated by correlational studies or historical analyses and lacks the depth and richness of direct experiences of individuals engaging with this phenomenon. This study sought to address this gap within psychological literature specifically, by conducting …

Changing The Face Of Reading Instruction: Do Culturally Relevant Passages Increase The Effects Of The Repeated Reading Intervention For Middle School Black Girls With Reading Difficulties (Bgrds)?, Olajumoke Edith Oshokoya

Electronic Theses and Dissertations

Research has shown that fewer studies have focused on improving the reading abilities of middle school Black girls (Morris, 2007). As BGRDs progress through K – 12 grades, they increasingly rely on basic and advanced reading skills (i.e., oral reading fluency [ORF] and comprehension) to learn. Providing BGRDs with engaging reading passages that are relevant to their prior knowledge, background, interests, and experiences, is more likely to motivate them to read, and eventually improve their reading skills (Cartledge et al., 2015). While there is a growing body of literature focused on Black students’ experiences, currently no study has explored the …

La Fiesta Del Espiritu Santo: An Original Work For Choir, Soloists, And Small Ensemble Influenced By The Santeria Music Of The African-Dominican Community In The Dominican Republic, Rafael Scarfullery

Electronic Theses and Dissertations

ABSTRACT

This study examines the role of Santería music as practiced by African Dominicans in Villa Mella, a neighborhood of Santo Domingo, Dominican Republic. This musical tradition comes from the culture and religion of the Yoruba people who were brought as slaves from Africa, and features complex drum rhythms and call-and-response chants. This paper deals with the historical and social context of Santería music within the Dominican Republic, but its principal objective is to adopt the musical language of this tradition and use it to create a new contemporary work for mixed choir and small ensemble.

One of the most …

Quantifying Current Soil Brine Contamination Within The Smackover Oil Field In Arkansas Using Multispectral Digital Imagery, Victoria Williams

Electronic Theses and Dissertations

A remote sensing study was performed to quantify current soil brine contamination across the historic Smackover Oil Field in south-central Arkansas, United States. The oil field was established in 1922 and was not subject to the future waste regulations created by the Arkansas Oil and Gas Commission. Brine is a waste product of oil manufacturing which contains water with high salt levels. The storage and transport of brine in the oil field created landscape scarring across the study area.

Landsat 9 multispectral digital imagery was utilized to create supervised classification maps based on earthen pits and creek scarring across the …

A Phenomenological Study Of The Perceptions Of Inclusive Preschool Education Through The Lens Of Interdisciplinary Early Childhood Educators., Brooke Noon

Electronic Theses and Dissertations

Young children with special needs have been educated in early childhood settings with typically developing peers for over 40 years. Successful educational inclusion in the least restrictive environment requires appropriate aids and supports (Individuals with Disabilities Act, 2004). Although researchers have studied many aspects of special education, little investigation has been conducted on the perspectives of dual certified interdisciplinary early childhood educator’s (IECE) perceptions on full inclusion in preschool. This study was designed to examine the connection between the perceptions of IECE teacher’s experiences as a dual certified educator in preschool. In total, 10 IECE teachers were interviewed and completed …
