A Call To Arms: A Comparative Study Of Mississippi And Kentucky Citizens During The Secession Crisis, 1859-1861, Amy Myers

Master's Theses

Many studies of the American Civil War have considered why Mississippi leaders voted to secede, while Kentucky politicians remained in the Union. Scholars have previously focused on political elites to understand the underlying motivations behind each state’s decision. These same scholars have often confined their studies to a synthesis of why secession occurred nationally or at the state level. The question remains as to what the common citizen saw and believed when faced with secession and if their views matched their delegates.

This study utilizes the governors’ papers of John J. Pettus and Beriah Magoffin, the Jefferson Davis papers, and …

Telescope Parallel Actuator Mount: Control And Testing, Samuel S. Artho-Bentz

Master's Theses

This thesis approaches the task of designing a control system for the Parallel Actuator Mount developed by Dr. John Ridgely and Mr. Garrett Gudgel. It aims to create a base framework that directly controls the telescope and can be expanded to accept external command. It incorporates lower priced components and develops more easily approachable software with great functionality. An open-loop method for velocity control is established. Developing repeatable tests is a major focus. Testing finds the control methods developed result in velocity error of less than 5% and position error of less than 1.5% despite several mechanical issues and inaccuracies. …

The Relationship Between Company, Manager, Group, And Individual-Level Variables And Affective Commitment, Varavit Chinnapong

Master's Theses

Predicting employees' affective commitment to their organization continues to be of strong interest to researchers. Previous studies have examined the relationship between specific organizational levels (company, manager, group, individual) and affective commitment. However, there is a lack of research that has analyzed all four levels in one study. Therefore, the current study sought to evaluate the relationships between the four organizational levels and affective commitment. More specifically, the current study analyzed human resources practices as the company-level variables, transformational and transactional leadership as the manager-level variables, group cohesion as the group-level variable, and psychological safety at the individual level. The …

The Moderating Effect Of Leadership Adaptability On The Relationship Between Employee Adaptability And Job Performance, Justine Davis

Master's Theses

The purpose of this study was to investigate the potential moderating effect of leadership adaptability on the relationship between employee adaptability and employee job performance. Previous research explored leadership adaptability as a mediator; however, there was a significant gap exploring leadership adaptability as a moderator. Participants were recruited via online social and personal networks. 125 participants completed a self-report survey consisting of items measuring employee adaptability, perceived manager adaptability and job performance. Results did not show perceived manager adaptability as a moderator of the relationship between employee adaptability and job performance. The results indicated that there were significant relationships between …

Investigation Of Dna Interstrand Crosslink Repair Using Bis-Epoxide Analogs, Sanjay Rakesh Kalliat

Master's Theses

DNA interstrand crosslinking is a form of lesion that affects biological processes such as DNA replication and transcription. Due to this phenomenon, interstrand crosslink (ICL) agents such as cisplatin and other platinum-based compounds find application in chemotherapy. However, ICL repair is not well understood in mammalian cells and has only been characterized thoroughly for prokaryotes such as Escherichia coli. We worked to explore the utility of bis-epoxides in the investigation of ICL repair. This involves synthesizing novel bis-epoxides that could potentially induce ICLs and test their efficacy in ICL formation using a DNA repair assay. It is known that bis-epoxides …

Inducing The Overview Effect Using Virtual Reality, Nhat Quang Le

Master's Theses

Astronauts who return from space missions have reported and demonstrated a significant increase in their feelings of connection to humanity and the planet. This shift towards a more humanistic, global perspective in astronauts was termed the “overview effect” by White (2014). There is a lack of research on the overview effect despite the significant, positive changes in those who have experienced it. This study aims to provide empirical evidence of and a possible induction method for the overview effect. We hypothesized that it might be possible to induce the overview effect using virtual reality (VR). In the current study, 81 …

The Relationship Between Authentic Leadership And Organizational Change Readiness: The Mediating Role Of Psychological Safety, Paulina Christine Manzano

Master's Theses

The purpose of the current study was to examine the mediating effect of psychological safety on the relationship between authentic leadership and organizational change readiness in the workplace. A total of 107 employees participated in the study, which utilized online survey distribution. Results showed that psychological safety partially mediated the relationship between authentic leadership and organizational change readiness. In other words, the more employees perceived their leadership to be authentic, the more likely employees felt safe taking risks at work, which in turn, increased employees’ emotional and cognitive inclination to adopt and embrace organizational change. Based on these findings, organizations …

Parental Influences On Adolescents' Risky Media Usage, Dahyeon Jung

Master's Theses

The present study investigated how parenting styles influence adolescents’ risky media usage and how these associations vary according to media-specific parenting practices and adolescent characteristics. Participants included 315 adolescents aged 13-18 in the United States, who completed questionnaires on parenting styles (i.e., authoritative, authoritarian, permissive), media-specific parenting practices (i.e., active conversational practices, coercive monitoring, preventive practices), and their depression, self-esteem, and risky media usage. Findings indicated all three parenting styles were associated with adolescent exposure to risk through media, but only authoritarian and permissive were related to internet addiction. Across parenting styles, adolescents with parents who engaged in high compared …

Easy In Any Language: Syntax, Semantics, And Pragmatics Of Activity-Oriented Adjectives In Six Languages, David Koffman

Master's Theses

Words that denote the degree of effort required for some activity, called easy adjectives here, have distinctive behavior. This behavior is explored in six languages to determine how the semantics of these words is reflected in the expressions to which they can apply, the constructions in which they appear, and their use in discourse. For four Indo-European languages, English, Spanish, German, and Russian, the analysis is based on random samples from linguistic corpora. For two non-Indo-European languages, Japanese and Swahili, the analysis is based on consultant elicitations and published examples. The analysis confirms that easy adjectives have distinctive behavior compared …

Effects Of Urbanization And Habitat On The Diet And Reproduction Of Red-Shouldered Hawks In Central California, Catherine Y. Fisher

Master's Theses

Urbanization alters biological community interactions and trophic structures compared to natural habitats; these changes may be reflected in the diets of apex predators such as raptors. The red-shouldered hawk (Buteo lineatus) is a dietary generalist that is expanding from natural and rural habitats into urbanized areas. In this study, direct observation was used to quantify the diet and reproductive success of red-shouldered hawks in Santa Clara County, California during the 2019 breeding season. GIS methods were used to quantify the nesting habitat and level of urbanization at each nest. Hawk diet consisted of mammals (50.4% by frequency and 77.7% by …

The Relationship Between Diversity Climate Perceptions And Organizational Citizenship Behavior And Work Engagement: The Mediating Role Of Overall Organizational Justice, Arika Nakajima Higgins

Master's Theses

Employees’ perceptions concerning their organization’s diversity climate have important implications for both the organization and the individual. Diversity climate research has traditionally focused on exploring the moderators of the relationship between diversity climate perceptions and the attitudinal outcomes of employees; however, research has neglected to examine behavioral outcomes and the potential mediators of the relationship. Therefore, the present study explored the indirect effects of overall organizational justice on the relationship between diversity climate perceptions and organizational citizenship behavior and work engagement. It was hypothesized that diversity climate perceptions would be positively related to organizational citizenship behavior and work engagement. It …

Transgenerational Plasticity Causes Differences In Uv-Tolerance Of Intertidal And Subtidal Populations Of The Purple Sea Urchin, Strongylocentrotus Purpuratus, Yareli Alvarez, Nikki L. Adams

Master's Theses

Planktonic larvae of marine organisms are increasingly being exposed and required to respond to a changing physical environment. Adult sea urchins occupy both intertidal and subtidal waters and broadcast spawn gametes into the water column to contend with variable physical conditions. To answer how populations of invertebrates residing at different depths adequately prepare their offspring to cope with different levels of ultraviolet radiation (UVR), we collected adult purple sea urchins, Strongylocentrotus purpuratus, from four sites (two intertidal and two subtidal (~15 m deep)) on the central coast of CA to compare UV tolerance in offspring. Our measurements of UVA …

Human Intention Inference Using Fusion Of Gaze And Motion Information, Daniel Trombetta

Master's Theses

Enabling robots with the ability to quickly and accurately determine the intention of their human counterparts is a very important problem in Human-Robot Collaboration (HRC). The focus of this work is to provide a framework wherein multiple modalities of information, available to the robot through different sensors, are fused to estimate a human's action intent. In this thesis, two human intention estimation schemes are presented. In both cases, human intention is defined as a motion profile associated with a single goal location. The first scheme presents the first human intention estimator to fuse information from pupil tracking data as well …

A Regional Vulnerability Assessment For The Dungeness Crab (Metacarcinus Magister) To Changing Ocean Conditions: Insights From Model Projections And Empirical Experiments, Halle Berger

Master's Theses

Among global coastal regions, the Northern California Current System (N-CCS) is already experiencing effects from ocean acidification and hypoxia during the summer, primarily due to the region’s seasonal upwelling, current systems, and high productivity. Oxygen, pH, and temperature conditions are expected to become more stressful with continued fossil fuel emissions under global climate change, posing a serious threat to the region’s fisheries. N-CCS fishing communities rely heavily on the economically and culturally important Dungeness crab (Metacarcinus magister). The fishery is currently sustainably managed, but potential negative impacts from changing ocean conditions on Dungeness crab life stages and populations …

The Use Of Low-Cost Sensors And A Convolutional Neural Network To Detect And Classify Mini-Drones, Austin Florio

Master's Theses

The increasing commercial availability of mini-drones and quadrotors has led to their greater usage, highlighting the need for detection and classification systems to ensure safe operation. Instances of drones causing serious complications since 2019 alone include shutting down airports [1-2], spying on individuals [3-4], and smuggling drugs and prohibited items across borders and into prisons [5-6]. Some regulatory measures have been taken, such as registration of drones above a specific size and the establishment of no-fly zones in sensitive areas such as airports, military bases, and national parks. While commercial systems exist to detect drones [7-8], they are expensive, unreliable, …

The Megaprocessor As An Educational Tool Making The Abstract Concrete, Jonathon Beauregard Ii

Master's Theses

Computer architecture courses can be difficult for students to engage with and learn from. This is because, unlike most core courses for a computer science student, learning architecture is an abstract process. To address this, universities have implemented methods for teaching course material other than purely descriptive methods. This typically means using simulations to model some aspect of a CPU or FPGA (fieldprogrammable gate array) boards for hands-on experimentation in CPU design. However, there are issues with these tools. Simulations can only cover a few topics well, are prone to being abandoned, and introduce additional abstraction layers. FPGAs, while great …

The Role Of Notch In Adipose-Derived Stem Cell Adipogenesis, Mengcheng Liu

Master's Theses

Obesity is the leading cause of chronic disease and has contributed to significant health problems and complications. In order to solve this increasingly serious social problem, it is particularly important to deepen the understanding of the biological causes of obesity. Obesity is the result of an increased mass of adipose tissue after excessive caloric intake, and adipogenesis is the main strategy through which the body increases the number of adipocytes. However, due to the lack of research, the current understanding of adipogenesis is not enough to yield results in the clinic.

The regulation of adipogenesis is complex, and the role …

Examining The Effects Of Disability Services On Student Success In Higher Education, Rebecca Smith

Master's Theses

Disabled students in higher education are provided resources through reasonable accommodation, or modification of university offerings. This affords the disabled student equal opportunity to benefit from those programs, services, and facilities despite the limitations imposed by their disability. This practice is historically informed by the medical model of disability, and legal reforms such as the Americans with Disabilities Act in 1990 and the Rehabilitation Act in 1973. Most research in this area has found that reasonable accommodation is effective for “leveling the playing field” for disabled college students. Yet, some researchers argue that Universal Design, the composition of an environment …

How Human-Centered Design Affects The Workplace, Alexandra Brigham

Master's Theses

This qualitative study was designed to explore the impact a workplace environment has on employees’ well-being and productivity. The research identified the themes of flattening, perception, unflattening, and well-being from a multidisciplinary approach including art education, fine art, architecture, medicine, philosophy, and science. Flatness is a state, a behavior that occurs when human perception and consciousness are narrowed, blocking sensory information that is not pertinent to a current task. Behavior that is perpetuated by ingrained societal systems and exacerbated by personal, professional, and financial stressors that can impact the human experience. Flattened areas are addressed in this study through a …

The Power Of Together: Applying Group Dynamics To Organizational Change Initiatives, Megan Bissell

Master's Theses

Work and occupations are among the oldest and most salient concepts studied in sociology. Sociology as a field has largely focused on organizations from a macro perspective; primarily looking at organizational systems and institutionalized systems of oppression. Conversely, in conjunction with other disciplines such as psychology, sociology has maintained a presence in the more micro space, focusing on individualized interaction and behaviors. However, there is a distinct lack of meso-level research about the impact of group dynamics and social interaction in the for-profit workplace. Since 2010, there have only been 89 articles published about groups and their interactions in the …

Assessing The Effects Of Habitat On Bird Song Propagation, Braelei Hardt

Master's Theses

The Acoustic Adaptation Hypothesis (AAH) posits that animal acoustic signals meant for long-range communication should be adapted to transmit well within the habitats in which they evolved. However, comparative studies investigating predictions of the AAH relating to signal form indicate that support for the hypothesis is not universal. Several studies have employed experimental playback approaches to testing signal transmission which can provide complimentary analyses to comparative studies of signal form in the field. Here, I first summarize these experimental playback tests of the AAH in birds, mammals, insects, and anurans, describing the methodologies used in these tests, and assessing the …

Artificial Night Lighting And Anthropogenic Noise Alter Animal Activity, Body Condition, Species Richness, And Community Structure, Joshua Willems

Master's Theses

Sensory pollution from artificial night-lighting and anthropogenic noise have increased at a dramatic rate over the last several decades. Alterations to the sensory environment have been found to affect wildlife in a wide variety of ways including behavioral changes, physiological responses, changes in species interactions, and altered community structure. Increased levels of light and noise pollution can originate from many sources including roads, energy development and infrastructure, and urbanization. Even remote or protected areas are not immune to the effects of increased sensory disturbances with 63 percent of protected areas within the United States found to have been exposed to …

Anger, Relational Victimization, And Vengeance In The Context Of Relational Aggression, Alison Poor

Master's Theses

Relational aggression involves the aggressor harming the victim’s social status, reputation, and/or relationships. This form of aggression is a relatively new topic in the literature that would benefit from additional research with emerging adults. The present study examined two models involving relational aggression in a college student sample (N= 247). First, we predicted, based on the general aggression model, that anger rumination would partially mediate the relationship between trait anger and relational aggression. Second, based on the rejection-aggression link, we predicted that vengeance would partially mediate the relationship between relational victimization and aggression. We tested each model separately …

Creative Expression Through The Gift Of God: The Intertwining Of Creativity And Religion Of The Poor Clares In New Orleans, Louisiana, Maureen Tierney

Master's Theses

This thesis looks at the relationship of art and creativity among the Poor Clares in New Orleans, Louisiana. Through the six sisters, the project addresses the way that religion influences the art that each sister produces. While each sister has had a different experience that drew them to religious life and their artwork, they all agree that their creativity is a gift from God, and this shapes how they engage with their art.

The literature gives an understanding to the role of the artist, and how to understand the nuance in an artist’s choice, when “why” something is produced is …

The Wakefield Phenomenon: A Rhetorical Examination Of The Resurgence Of The Anti-Vaccination Movement In The 20th & 21st Century, Karen Boger

Master's Theses

This thesis explores the phenomenon of the anti-vaccination movement and existing publications documenting significant points in its resurgence in the late 20^th and early 21^st century following the now redacted publication by the former Dr. Wakefield asserting a correlation between children receiving vaccinations and children exhibiting the onset of developmental disorders, with Autism Spectrum Disorder (ASD) garnering the most public attention. With increasing numbers of parents delaying or forbidding their children from receiving vaccinations, along with the re-emergence of previously eradicated disease outbreaks and casualties, questions about the salience of Wakefield’s anti-vaccination statements arise. Investigation here is key …

Does Race Matter? An Examination Of Defendant Race On Legal Decision Making In The Context Of Actuarial Risk Assessments, Riley Davis

Master's Theses

Numerous examples show how consideration of extra-legal factors, like defendant race, in legal decision-making are contributing to the overrepresentation of minorities in the legal system. Because triers of fact may be less familiar with risk assessment results presented by expert witnesses, there is a need to examine how legal decision-making is being affected by race in this context. This study aimed to examine whether individuals are in fact relying on race as a factor above empirically supported expert opinions of actual violence risk predictions. The sample consisted of 280 participants recruited from Amazon’s Mechanical Turk. To test the primary hypothesis …

Non-Religious Employee's Perceptions Of Microaggressions And Their Relationship With Job Satisfaction As Moderated By Calling, Jessica Schultz

Master's Theses

The purpose of this study was to investigate the relationships between microaggressions, person-organization fit (P-O fit), job satisfaction, and calling in non-religious individuals. Established research demonstrates that job satisfaction is predicted by P-O fit (Dawis, 2005). Research with minority groups has found that microaggressions are negatively related to P-O fit and job satisfaction (Lyons, Velez, Mehta, & Neil, 2014). However, research has yet to examine these interactions with a non-religious population. Previous investigations have found that calling is positively correlated with both P-O fit and job satisfaction (Duffy & Dik, 2013; Duffy, Allan, & Dik, 2011; Hirschi, 2012), suggesting the …
