Virtual Faces In Virtual Spaces: Generating Social Capital In An Online World, Raymond James Miran

Graduate Research Theses & Dissertations

This thesis examines how online virtual reality games can generate social capital in the

social video game VRChat. Past research explores the generation of social capital from social

media and video games. These platforms generate social capital through different processes.

These differences are due to the technological differences and divergent purposes of the

platforms. VRChat bridges the computer-mediated-communication platforms as a social video

game. This thesis examines how VRChat as an online virtual reality generates bridging and

bonding online social capital by combining elements of the two platforms.

Results from 21 in-depth interviews showed that players of VRChat generated both …

Partial Shading In Photovoltaic Cells Using Fuzzy Logic Tuned Particle Swarm Optimization Method Of Maximum Power Point Tracking Control, Nauman Moiz Mohammed Abdul

Graduate Research Theses & Dissertations

This paper dealt with the study of a newly modified fuzzy adaptive particle swarm

optimization controller and compared it with various existing conventional and advanced

controllers. A traditional PSO controller has the problems of oscillations and slow convergence. It is modified using fuzzy logic to decrease the number of oscillations and optimize

the convergence speed to produce a better efficient output. This controller is built to adapt

under various solar irradiances and partial solar conditions on the solar panels. This controller is then tested along with other various controllers, results recorded and studied. The

simulations are performed on the MatLab …

“I Never Shared My Opinion Again”: Political Communication Apprehension And Conservative College Students, Megan Elise Montgomery

Graduate Research Theses & Dissertations

Higher education faculty have long struggled with getting students to participate meaningfully in classroom and campus dialogues. Some students avoid participating due to fear or anxiety of communicating with others. Certain topics, such as politics, can cause higher degrees of apprehension. Political minority groups can experience greater apprehension when communicating with majority groups. One minority group in academia with the potential to self-censor is the conservative student.

This study used state-based communication apprehension (McCroskey, 1984) and political communication apprehension (PCA, Jones-Carmack, 2019) as theoretical backings to explore how conservative opinion expression and self-censorship in academic settings might change over time. …

Single-Domain Vhh Antibodies As Protein Stabilization Modules, Nourhan Mohamed Disouky Mostafa

Graduate Research Theses & Dissertations

VHH domains are the antigen-binding units found in heavy-chain-only antibodies from the Camelidae family (e.g., camels and llamas). They are considered a unique minimalist antibody scaffold due to the lack of a variable light chain domain. Despite having half the antigen-binding interface of conventional antibodies, these VHH antibodies bind their target antigens with affinities comparable to conventional antibodies. This project explored how flexible linkers connecting an anti-GFP VHH (αGFP VHH) domain to its antigen (EGFP) enhanced antigen stability and influenced oligomeric assembly. It was hypothesized that linking the anti-GFP VHH antibody to its target antigen (EGFP) will increase the local …

Investigating The Behavioral Effects Of Juvenile Stress In The Prairie Vole Model, Marigny C. Normann

Graduate Research Theses & Dissertations

Early life stress during the juvenile period, such as emotional neglect, interpersonal difficulties, or other forms of non-violent maltreatment can have consequences into adulthood. Specifically, the negative effects include increased risk of psychiatric or physical illnesses, social deficits, and maladaptive behavioral responses to stress. Since these effects have far-reaching implications that can negatively alter later behavior and physiology, the present study assessed the effects of early life social stress on later social and affective behaviors in a social rodent species – the prairie vole. The prairie vole displays behavioral, cardiovascular, and neuroendocrine responses to social stress similar to those of …

Rational Design Of Memory-Based Sensors: The Case Of Molecular Calorimeters, Obianuju Augusta Nwokolo

Graduate Research Theses & Dissertations

Thermodynamic characterization is crucial for understanding molecular interactions. However, methodologies for measuring heat changes in small open systems are extremely limited. We document a new approach for designing molecular sensors that function as calorimeters: sensors based on memory. To design a memory-based sensor, we take advantage of the unique kinetic properties of nucleic acid scaffolds. Particularly, we elaborate on the differences in folding and unfolding rates in nucleic acid quadruplexes. DNA-based i-motifs unfold fast in response to small heats but do not fold back when the system is equilibrated with surroundings. We translated this behaviour into a molecular memory function …

Why Some Authoritarian Regimes Do Not Just Win Elections But Win Big: Lessons From Cambodia And Malaysia, Limeng Ong

Graduate Research Theses & Dissertations

Electoral authoritarian regimes have risen in the post-Cold War era. Elections and other nominally democratic institutions such political parties and legislatures not only do not make authoritarian regimes democratize but also help them to resist democratization. However, even if authoritarian regimes adopt electoral institutions, such adoption does not mean that all authoritarian regimes can easily manipulate elections. Indeed, some regimes hang on to power barely with simple majority votes, while others easily receive supermajority electoral support. What account for variation in electoral strength of ruling parties in authoritarian regimes? I attempt to answer this question. There are four main factors …

Today, researchers are inundated with an overwhelming amount of data due to advances in DNA sequencing technologies. This has benefited the fields of both bioinformatics and phylogenomics substantially. With the ability to increase sampling at both the taxonomic and molecular levels, we are now able to produce robust phylogenomic reconstructions and better discern relationships between taxa.

The goals of this dissertation are in two distinct parts: 1) to advance the understanding of land plant terrestrialization and evolution through examination of the closest relative to the land plant lineage, a species of green algae; and 2) to explore evolution among a …

The Role Of Medial Septum Cholinergic Function In Processing Self-Movement Cues To Maintain Spatial Orientation, Jenna Rae Osterlund

Graduate Research Theses & Dissertations

Wandering is the most life-threatening and commonly reported symptom of Alzheimer’s Disease (AD), a neurodegenerative disorder characterized by an inability to maintain spatial orientation. The often deadly consequences of wandering are projected to rise in the coming decades due to the advancing aged population. These upcoming challenges necessitate a more comprehensive understanding of the neurobiology of spatial orientation in order to evaluate novel therapeutic techniques for symptoms such as wandering. The inability to maintain spatial orientation in AD may be due to the pathological degeneration of the hippocampal cholinergic system. This neurological system is conserved across species for its function …

Links Between Parenting Behaviors And Anxiety Among Early Adolescents, Jacqueline Marie Pabis

Graduate Research Theses & Dissertations

This study aimed to specify factors, particularly parenting behaviors and gender, that influence the development of anxiety symptoms during early adolescence. Past research tends to incorporate a large age range; thus, this study focused on early adolescence which involves a change in the dynamics of the parent-child relationship such that children become less dependent on their parents. The study collected data from 153 middle school students (Mage = 12.71 years; 54.2% female; 48% White) using an online data collection instrument during study hall periods in the school day. Partial correlations revealed that rejection among both parent figures is the greatest …

An Online Randomized Controlled Trial Of Mindful Parenting Among Parents Of Children With Autism Spectrum Disorder, Emily Elizabeth Padgett

Graduate Research Theses & Dissertations

Parents of children with autism spectrum disorder (ASD) often experience stress and other psychological symptoms associated with their role as a parent. Mindfulness, defined as purposefully paying attention and nonjudgmentally remaining in the present moment, and mindful parenting, the application of mindfulness to the parent-child relationship, have been found to improve psychological functioning for individuals more broadly and parents specifically. Additionally, experimental mindful parenting interventions have been found to improve multiple outcomes in parents, including mindfulness, mindful parenting, parenting stress, anxiety and depression, and self-compassion. However, experimental research to date has not yet examined an online, self-guided mindful parenting intervention, …

Speculative Satire In Twentieth-Century Utopia And Dystopia, Benjamin Craig Parker

Graduate Research Theses & Dissertations

This study integrates the literature and correspondence of such Inklings authors as C. S. Lewis and J. R. R. Tolkien into the arc of Commonwealth utopian and dystopian literature of the late nineteenth and twentieth centuries. Because utopian authors such as Samuel Butler, William Morris, and H. G. Wells employ the utopian form pioneered by Thomas More but largely abandon More’s Augustinian Catholic view of human nature, their works frequently fail to address the impediments to justice and equity that More satirically addresses in Utopia. Thus, the speculative fiction of later Augustinian Christian authors such as Lewis and Tolkien complements …

A Multi-Constraint Predictive Control System With Auxiliary Emergency Controllerfor Autonomous Vehicles, Farhad Partovi Ebrahimpour

Graduate Research Theses & Dissertations

In the last few years, several research groups and companies have worked on developing autonomous vehicles. Among the first automation layers, the safety layer plays a significant role in this field. However, considering safety should not diminish the importance of the efficiency of the vehicle in terms of path tracking with the desired speed. This thesis introduces a multi-constraint predictive control algorithm along with a safety layer to guarantee object avoidance in emergency situations. First, there is a quick review of autonomous cars and their functionalities. In the following, a controller switching mechanism is proposed and designed. It switches the …

Molecular Dynamic Simulations Of Mechanical Properties In Nb-Nbc Core-Shell Nanowires And Nodes, Austin Pauga

Graduate Research Theses & Dissertations

Nanoporous materials have attracted attention recently because of their extensive range of possible applications. These nanoporous materials are comprised of nanowires and nodes. A node joins three or more nanowires of different orientations. Current research has focused on nanowires and nodes composed of metallic single crystals and core-shells. Nanoporous materials experience brittle failure from the rupture of the weakest feature, overloading the other remaining structural features. To alter the deformation behavior of the network nodes, a ceramic layer has been added around the metal. Coating the metallic ligaments with ceramic shell increases the buckling capacity of each ligament and further …

Often Overlooked, But Not Forgotten: The Influence Of Demographic Measure Constraints On Participant Affect, Attitudes, Behavior, And Response Codability, Joy S. Pawirosetiko

Graduate Research Theses & Dissertations

Despite a growing number of recommendations varying in wording and response options, researchers have yet to agree on how to best request participant gender identity. Evidence suggests that gender binary and gender minority participants perceive gender identity measures differently, with gender binary participants potentially perceiving more gender inclusive measures as laborious and gender minority participants perceiving less gender inclusive measures as misgendering or invalidating. We sought to test whether seven versions of an online questionnaire (six experimental conditions with gender identity questions listed at the beginning of the questionnaire varying in gender inclusivity, and one control condition) significantly impacted participant …

College Leadership Opportunities' Impact On Life During And After College, Mark Anthony Pietrowski Jr.

Graduate Research Theses & Dissertations

This study explores the personal experiences of 14 individuals who engaged in leadership opportunities during their college educations. Through in-depth interviews, this study sought to explore how those leadership experiences impacted their leadership, both in their careers and/or in the community, after their graduation from both 2 and 4-year institutions. Findings from this study indicate that participants identified that their leadership experiences had impacts upon their careers and leadership after graduation. Yet, participants also shared that they engaged in leadership because they were self-motivated to do so, rather than learning about these opportunities on their campus. The final finding indicated …

The Second Prong Of The Tinker Test: A Constitutional Right To Not Be Offended?, Jonathan Pilkington

Graduate Research Theses & Dissertations

In the landmark 1969 Tinker v. Des Moines case, the Supreme Court ruled school districts could censor student speech if it caused a material and substantial disruption to the educational process or if the speech infringed upon the rights of others. Since then, the Supreme Court has also allowed schools to abridge students’ speech rights if the speech was obscene, if the speech was part of a school-sponsored activity, or if the speech promoted illegal drug use. Most of the court cases since Tinker have applied the first prong of the Tinker decision, focusing on disruption to education as the …

Principals’ Legal Literacy About Tenured-Teacher Evaluation In Illinois, Elizabeth Pohlmann

Graduate Research Theses & Dissertations

This dissertation examines the legal literacy of principals related to the evaluation of tenured teachers. The quality of teachers, while varied, is important. The evaluation of tenured teachers provides a significant opportunity to impact the quality of teachers and the teacher workforce. This study explores principals’ knowledge of the legal framework in Illinois to identify gaps in knowledge regarding the tenured teacher evaluation process and the associated legal constraints (what do they have to do) and opportunities (what can they do).

In this study, a survey aligned with the legal requirements for tenured teacher evaluation is used to measure principal …

Categorization Of Orthologous Gene Clusters In 92 Ascomycota Genomes Reveals Functions Important For Fungal Phytopathogenicity, Daniel Curtis Peterson

Graduate Research Theses & Dissertations

Ascomycota fungi are mostly saprophytic in nature, living off dead or decaying matter. However, a small subset of these fungi possess the ability to infect live hosts and cause disease while obtaining nutrients. Phytopathogenic Ascomycota are responsible for substantial economic losses each year, destroying valuable crops. Previous genomic studies have been conducted to annotate sequenced genes and proteins of these fungi with predicted functions, and those annotations are publicly accessible through online databases. Through these means, several genes have been identified to play a role in pathogenicity in some agriculturally relevant fungi. Through a bioinformatic analysis approach the present study …

Improving The Efficiency Of Planar Goubau Line And Goubau-Line-Based Endfire Antenna, Sreelakshmi Radhakrishnan

Graduate Research Theses & Dissertations

This thesis presents the use of two dielectric layers in a planar Goubau line (PGL) to improve its transmission efficiency compared to the existing single-layer models, which is less than 70% efficient at lower frequencies up to 5 GHz. Further, as an extension of the thesis, the possibility of obtaining directive radiation pattern with radiation efficiency greater than 89.6% using a Goubau-line-based antenna is studied. While none of the existing Goubau-line-based antennas are able to obtain an endfire pattern with radiation efficiency of above 80%, the proposed model utilizes stubs that are periodically attached to the main line of length …

Southern Electoral Strategy: The Strategic Integration Of Religious Values Into The Republican Party Platform, Levi Walker Rattliff

Graduate Research Theses & Dissertations

There has been substantial literature concerning the effect the Republican southern strategy had on the Southern voting realignment following the passage of the 1964 Civil Rights Act. This literature has singularly focused on the role of race issues as a wedge disrupting the Southern Democratic majority. During the early stages of this process race did play an integral role, but closer to modernity, the emergence of religious issues serves as a better causal mechanism that has been largely overlooked. Meaning that as racial issues became less salient and palatable in nationwide presidential elections, the Republican Party strategically incorporated social issues …

This thesis examines how power operates within the NGOs and how NGOs’ agenda interacts with local forces that transform local civic life and their relationship with the state. Using critical ethnography as an approach and methodology, this study investigates the relationship between the agenda that was developed by an NGO-like institution named the UGM and the Mollonese’s local politics that in turn affected the NGO-state relationship in West Timor. This study uses ethnographic data from two separate fieldworks in the district of North Mollo, Timor Island. The first was conducted from January 2016 to January 2017, the second was from …

Construction Of Confidence Intervals For Parameter Estimates Of T-Distribution, Margaret Remus

Graduate Research Theses & Dissertations

Constructing confidence intervals is a standard statistical practice to estimate parameters of a distribution. Estimation of the parameters of a t-distribution can be computationally intensive. As a result, there are not clear defined formulas for the construction of confidence intervals for those estimates. Using the Normal confidence interval equation does not offer an accurate interval. Therefore, this paper will outline potential alternative methods for building confidence intervals to estimate the mean of a t-distribution. This paper will offer several methods and simulations to determine which method is best for constructing confidence intervals for varying sample sizes and degrees of freedom. …

Bully Participant Role Behavior And Social Support From Teachers And Classmates: A Longitudinal Conditional Process Analysis, Logan Riffle

Graduate Research Theses & Dissertations

Youth are involved in a range of bullying-related behaviors. Unfortunately, engagement in such behavior is associated with a variety of poor outcomes and thus it is important to understand the mechanisms behind this phenomenon as well as associated variables such as perceived teacher support and classmate support, as both types of support have been associated with engagement in bullying situations. Using Bronfenbrenner’s Social Ecological Model (Bronfenbrenner, 1977) as a backdrop, the aim of the current study was to investigate the longitudinal associations between bullying participant role behavior and perceived support from teachers and classmates. Specifically, this study examined the mediating …

“The Cause, It Just Comes First”: Tori Amos And Third-Wave Feminism, Amanda S. Roberts

Graduate Research Theses & Dissertations

This dissertation is a textual analysis of Tori Amos as a feminist artist. Because Amos has had a successful and enduring career, she presents a unique opportunity to explore the ways third-wave feminism has influenced popular culture and vice-versa. This dissertation utilizes both a feminist and cultural studies lens to understand Amos, her work, and her fan community as texts. Through a chronological study of Amos’s catalog, I will demonstrate how Amos’s works have adapted to the demands and interests of third-wave feminism, moving from emotional non-narrative, to active political engagement with some mis-steps, and finally to an understanding of …

Maternal Parenting Behavior, Socioeconomic Risk, And Toddler Effortful Control: The Mediating Role Of Infant Attention, Leanna D. Rosinski

Graduate Research Theses & Dissertations

Effortful control (EC), the regulatory component of temperament, has important implications for children’s emotional, behavioral, and physical health. Greater infant attention regulation, a skill which develops prior to the emergence of EC, predicts better EC later in childhood. In addition, higher socioeconomic status (e.g., greater education, higher income) predicts better infant attention regulation and child EC. Negative parenting, characterized by intrusive, insensitive interactions with expressions of negative affect, has been found to predict poorer infant attention and child EC. Given these findings, the current study examined infant attention as a mediator between socioeconomic status, negative parenting, and toddler EC. A …
