Thither The Russian Navy? Putin’S Navalization In A Historical Context, William Emerson Bunn

Graduate Program in International Studies Theses & Dissertations

The Syrian operation of 2012 was the first successful employment by Russia of expeditionary warfare, narrowly defined as naval support to Russian (or Soviet) ground forces in a war away from their periphery (i.e., in a country that does not border them), from the sea. This was brought about in part by the development of two types of cruise missiles: advanced anti-ship missiles (which protects their expeditionary force from NATO naval units, enabling local sea control) and new land attack cruise missiles (similar in design and capability to the U.S. Tomahawk). In the past geographical, technological and political constraints …

Remittance: A New Instrument For Change -- Understanding The Impact Of Remittances On Home Countries Development, Alex M. Hamed

Graduate Program in International Studies Theses & Dissertations

This dissertation constructs a framework to investigate the impact of remittances on the recipient countries in the context of the Middle East and North Africa (MENA) and the European Union (EU). The framework will explore the effects of labor migration induced by bilateral labor agreements (BLAs). Such labor agreements are guided by the desire of autocratic governments to utilize their citizens to finance social contracts to sustain the authoritarian systems. The labor movements are further enhanced by accumulating social capital and remittances. The research also highlights the impact of remittances on the home country's institutional quality. It also highlights the …

Combining Cognitive And Noncognitive Assessments To Predict First Year Gpa And Persistence In Community College Students, David Harris Larman

Educational Foundations & Leadership Theses & Dissertations

Standard assessments of cognitive ability have been the preferred method of assessing the probability of student achievement at community colleges, but there is a growing trend in the use of noncognitive factors to assess student potential. Factors related to a student’s race/ethnicity and family income have been shown to be correlated with placement tests scores and high school grades. There is a gap in the literature about the use of noncognitive measures in conjunction with standardized placement tests to predict the achievement and persistence of community college students. The purpose of this study was to examine the strength of cognitive …

Dual Energy Electron Storage Ring Cooler Design For Relativistic Ion Beams, Bhawin Dhital

Physics Theses & Dissertations

Collider experiments demand small beam emittances in order to achieve high luminosity. For light particles such as electrons, there exists a natural synchrotron radiation damping resulting in low emittance beams at equilibrium. In the case of heavy particle beams such as proton or ion beams, there is no significant synchrotron radiation damping effect and some cooling mechanism is needed to get to low emittance beams. A dual energy storage ring cooler is a novel concept proposed to cool hadron beams at higher energies. The design consists of two rings: a low energy ring and a high energy ring connected by …

Characterization Of Losses In Superconducting Radio-Frequency Cavities By Combined Temperature And Magnetic Field Mapping, Ishwari Prasad Parajuli

Physics Theses & Dissertations

Superconducting radio-frequency (SRF) cavities are one of the fundamental building blocks of modern particle accelerators. To achieve the highest quality factors (10¹⁰-10¹¹), SRF cavities are operated at liquid helium temperatures. Magnetic flux trapped on the surface of SRF cavities during cool-down below the critical temperature is one of the leading sources of residual RF losses. Instruments capable of detecting the distribution of trapped flux on the cavity surface are in high demand in order to better understand its relation to the cavity material, surface treatments and environmental conditions. We have designed, developed, and commissioned two novel …

T-Cell Antigen Receptors In Multiple Sclerosis, Lisa Lanée Keyes Jones

Biomedical Sciences Theses & Dissertations

Multiple Sclerosis (MS) is T-cell mediated autoimmune disease characterized by inflammation, demyelination, and degeneration of axons in the brain and spinal cord. A T cell-mediated immune response in MS is directed against myelin components and possibly other antigens in genetically susceptible individuals and is triggered by a viral infection. The T-cell antigen receptor (TCR) on T cells is responsible for antigen recognition and determines specificity. Our overall hypothesis is to determine whether clonally expanded T cells in patients with MS recognize viral or self-antigens and to determine whether molecular mimicry is involved in the development of the disease. To study …

Values And Power As Levers To Influence Accountability Policy In Virginia: A Case Study, Angela M. Rhett

Educational Foundations & Leadership Theses & Dissertations

The education landscape has been inundated in recent decades with a plethora of accountability measures. New mandates and processes are conceived at the hands of policymakers, and concepts such as power and values are at the core of accountability changes. The purpose of this research study was to uncover the web of unwritten structures and systems in place that influence the educational accountability policy process using complexity theory as the guiding theoretical framework (Shoup & Studer, 2010). Complexity theory dispels the notion of simplistic cause and effect relationships as predictors for accountability trends, and, instead, posits the multiplicity of factors …

A Relevance Model For Threat-Centric Ranking Of Cybersecurity Vulnerabilities, Corren G. Mccoy

Computer Science Theses & Dissertations

The relentless and often haphazard process of tracking and remediating vulnerabilities is a top concern for cybersecurity professionals. The key challenge they face is trying to identify a remediation scheme specific to in-house, organizational objectives. Without a strategy, the result is a patchwork of fixes applied to a tide of vulnerabilities, any one of which could be the single point of failure in an otherwise formidable defense. This means one of the biggest challenges in vulnerability management relates to prioritization. Given that so few vulnerabilities are a focus of real-world attacks, a practical remediation strategy is to identify vulnerabilities likely …

Creating More Equitable Opportunities In Early Childhood By Highlighting Parent Voice: A Qualitative Case Study, Julie Dawn Sill

Teaching & Learning Theses & Dissertations

This qualitative, single embedded case study, framed on Bioecological Systems Theory, Adult Learning Theory, and a Family-Systems Intervention Model investigates the reasons parents and caregivers of young children enroll in and complete parent education classes during the birth to three-year period, as well as the supports that may contribute to positive early parent-child communication or the barriers that may prevent these interactions from occurring (Bronfenbrenner, 2005; Dunst & Trivette, 2009; Knowles et al., 2020). Convenience sampling was used to recruit adult participants from a community organization in the Southeastern USA whose mission was to improve the school readiness of its …

Advanced Generalized Predictive Control And Its Application To Tiltrotor Aircraft For Stability Augmentation And Vibration Reduction, Thomas Glen Ivanco

Mechanical & Aerospace Engineering Theses & Dissertations

The goals of this research were to restore generalized predictive control (GPC) capability at NASA and within the community, to better understand GPC and its performance relative to other options, and to improve upon the capability of GPC. Unique to this research is the comparison of GPC with other control options including PID controllers, optimal control theory, and other versions of the similar AutoRegressive moving average model with eXogenous inputs (ARX) models. Similar to GPC, ARX models use an experimentally acquired system identification to characterize the input/output relationship between controls and response measurements. Because this relationship is determined from acquired …

Hiding In Plain Sight: A Phenomenological Exploration Of Black Male Educators In School Leadership, Jeryl Kimbrough-Scott

Educational Foundations & Leadership Theses & Dissertations

With the changing landscape of America’s K-12 student population becoming a myriad of ethnicities, the importance of diversifying school leadership is critical to reflect the varying groups represented in the student population. Khalifa et al. (2016) and Talbert-Johnson (2006) attest that the development of culturally responsive programs is necessary to address the needs and experiences of a diverse population. Similarly, the premise of teacher preparation programs that are predominantly white and middle class need additional initiatives to better prepare candidates in working with diverse populations (Browne-Ferrigno, 2011; Carpenter & Diem, 2013; Ford et al., 2020; Hampton et al., 2008; Khalifa, …

Case Study Of A District-University Partnership: Developing Culturally Responsive Educators In A Rural Setting, Trenice Shauntel Durio

Educational Foundations & Leadership Theses & Dissertations

Using a theoretical framework of critical race theory and conceptual frameworks of cultural education, this study explores the intersection of district-university partnerships and culturally responsive education. The purpose of this mixed methods case study was to examine the formulation and outcomes of a district-university partnership established to offer a college level course focused on anti-discrimination, equity and inclusion, and social justice in schools. Using survey data, I explored the relationship between participation in the course and the participants’ self-reflection in the areas of empathic concern and perspective taking, preparation for culturally responsive teaching and equitable practices, and comfortability with discussions …

Hieronymus Bosch's Dismantled Triptych And The 'Devotio Moderna', Mary E. Tippett

Institute for the Humanities Theses

Flemish painter Jeroen van Aken, better known as Hieronymus Bosch, created a triptych depicting the folly of humanity. This dismantled triptych includes the Ship of Fools, the Allegory of Intemperance, the Death of the Miser, and the Rotterdam Wayfarer, completed between 1500 and 1510. Throughout his career, Bosch explored a peculiar take on the traditional forms of wellknown religious motifs throughout Renaissance Europe by populating his scenes with fantastical creatures and monsters. Scholars have long since suggested that these forms were inspired by illuminated manuscripts. However, scholars provided no explanation as to why these texts drew …

The Creation Of Successful Student Subjects: Foucault’S Power/Knowledge Framework And The Danger Of Failing Early Alert, Sue Ann Cecilia Curran

Educational Foundations & Leadership Theses & Dissertations

The purpose of learning analytics is to improve and optimize learning using student data (Siemens, 2013). An early alert warning is learning analytics designed to promote student success (Baneres et al., 2019; Foung, 2019; Lawson et al., 2016; Villano et al., 2018). An early alert has an intervention component that includes, at minimum, an email that provides information about college resources to address the issue (Arnold & Pistilli, 2012). Some early alert interventions include a personal outreach by a staff member at the college through a phone call or text message (Choi et al., 2018).

At Care Community College, when …

Cyber Resilience Analytics For Cyber-Physical Systems, Md Ariful Haque

Electrical & Computer Engineering Theses & Dissertations

Cyber-physical systems (CPSs) are complex systems that evolve from the integrations of components dealing with physical processes and real-time computations, along with networking. CPSs often incorporate approaches merging from different scientific fields such as embedded systems, control systems, operational technology, information technology systems (ITS), and cybernetics. Today critical infrastructures (CIs) (e.g., energy systems, electric grids, etc.) and other CPSs (e.g., manufacturing industries, autonomous transportation systems, etc.) are experiencing challenges in dealing with cyberattacks. Major cybersecurity concerns are rising around CPSs because of their ever-growing use of information technology based automation. Often the security concerns are limited to probability-based possible attack …

Integrative Physiology-Coupled Pilot-Centered Flight Simulation, Shawn C. Harrison

Electrical & Computer Engineering Theses & Dissertations

Maintaining the pilot’s physiological performance envelope within the limits of human capabilities may be crucial for avoiding hazardous physiological episodes in fighter aircraft that compromise safety. The main physiological episode of interest is impaired pilot respiration, better known as hypoxia caused by a high fraction of inspired oxygen (FiO₂) at high altitudes and variation in accelerative gravitational forces (g-forces). Integrated into fighter aircraft is an Onboard Oxygen Generating System (OBOGS) developed to mitigate the necessity of gaseous and liquid oxygen cannisters [1]. OBOGS act as a life support in hypoxic environments by providing oxygen-rich air, thereby oxygenating the …

Detection, Tracking, And Classification Of Aircraft And Birds From Multirotor Small Unmanned Aircraft Systems, Chester Valentine Dolph

Electrical & Computer Engineering Theses & Dissertations

The ability for small Unmanned Aircraft Systems (sUAS) to safely operate beyond visual line of sight (BVLOS) is of great interest to governments, businesses, and scientific research. One critical element for sUAS to operate BVLOS is the capability to avoid other air traffic. While many aircraft will be cooperative and broadcast their locations using Automatic Dependent Surveillance Broadcast (ADS-B), it is expected that many aircraft will remain non-cooperative – meaning they do not communicate position or flight plan to other aircraft. Avoiding mid-air collisions with non-cooperative aircraft is a critical limitation to widespread sUAS flying BVLOS. Examples of non-cooperative traffic …

Development And Validation Of A Three-Dimensional Optical Imaging System For Chest Wall Deformity Measurement, Nahom Kidane

Electrical & Computer Engineering Theses & Dissertations

Congenital chest wall deformities (CWD) are malformations of the thoracic cage that become more pronounced during early adolescence. Pectus excavatum (PE) is the most common CWD, characterized by an inward depression of the sternum and adjacent costal cartilage. A cross-sectional computed tomography (CT) image is mainly used to calculate the chest thoracic indices. Physicians use the indices to quantify PE deformity, prescribe surgical or non-surgical therapies, and evaluate treatment outcomes. However, the use of CT is increasingly causing physicians to be concerned about the radiation doses administered to young patients. Furthermore, radiographic indices are an unsafe and expensive method of …

Can Obsessive Thoughts Predict Problematic Alcohol Use Through Thought Suppression?, Laura Pettigrew

Psychology Theses & Dissertations

Alcohol misuse, which is a prevalent issue among college students, often coincides with psychiatric disorders or symptoms. Treatment of one facilitates treatment of the other. Some anecdotal evidence suggests that obsessive-compulsive disorder (OCD), or just obsessive-compulsive symptoms, is connected to alcohol misuse.

This study adapts part of the cognitive control model of OCD, which states that intrusive thoughts will only lead to distress if the individual interprets them in a dysfunctional manner and tries to control them. When the thought control attempt fails, if the individual interprets the failure in a dysfunctional way as well, they will become distressed. If …

Work Beyond The Work: Amplifying How Black Women Educators Experience Teacher Preparation Programs, Chéleah Victoria Googe

Educational Foundations & Leadership Theses & Dissertations

The representation of Black teachers in the field of K-12 education has declined significantly in the last forty years (Ingersoll, 2011; Milner & Howard, 2004). Once considered a pathway to the middle class for Black Americans, teaching was a sought-after profession for Black folks for job stability (Collier, 2002). While there is extensive research on the experiences of teachers of color, and what might lead to their attrition in the teaching profession, Black women experience a specific intersection of race, class, and gender that affects their sustainability in the teaching profession that deserves exploration.

This qualitative research study examined the …

Social Emotional Competency Change During The Pandemic: Impacts Of A Virtual Physical Activity Program, Austin Kulp

Human Movement Sciences & Special Education Theses & Dissertations

There is currently limited research on virtual physical activity (PA) programs and their relationship on social emotional competency (SEC). Therefore, the purpose of this study was to examine the effect of a virtual after-school PA program has on SEC among elementary school students. The participants of this study are 122 elementary school students (Mean Age=11.69) enrolled in grades 2-6 from six elementary schools. Children registered and participated in the virtual after-school PA program Move 60!, that was offered four times per week during the pandemic (Fall 2021 from October to December). SEC was measured using the Washoe County School …

Trauma And Crisis Counselor Preparation: The Relationship Of An Online Trauma And Crisis Course And Counseling Self-Efficacy, Julia Leigh Lancaster

Counseling & Human Services Theses & Dissertations

The field of trauma and crisis is growing and ubiquitous to all counseling specialties. Updates in 2009 and 2016 to the Council for Accreditation of Counseling and Related Educational Programs (CACREP) counselor preparation standards added mandated teachings on crisis, trauma, and disaster counseling in counselor preparation programs’ (CPPs) curricula. Since then, some CPPs have created stand-alone crisis courses, while the majority have infused various related content and trainings into already established counseling courses. Research does, in fact, support an increased crisis, trauma, and disaster readiness with more hours dedicated to the study and practice of domain specific content, and confirms …

Family Writer's Workshop: A Case Study, Alisa Innes

Teaching & Learning Theses & Dissertations

Today’s students need to be prepared for a successful future in our competitive world. Families and educators need to work together to provide children with a comprehensive literacy foundation. Currently, there are many school-based and community-based family literacy programs that are being implemented. While these programs are successful, they are missing a crucial component: writing intervention. Writing is a skill that our students will need for higher education and future careers.

The problem for this study was that research is lacking in regards to ways to assist parents who are interested in working on writing with their child outside of …

Centering Community College Students' Experiences: A Multiple Methods Study Of Multiple Measures For Writing Placement, Nicole L. Hancock

English Theses & Dissertations

Community colleges are trying to reform their placement procedures from use of a single placement test score to a system that collects multiple measures to be used either as a replacement solitary measure or in conjunction with other measures for more accurate placement into writing courses than what occurred with the placement test, which often resulted in disparate impact for students of color. In this study of multiple measures placement assessment for writing courses, I critique several large studies of community college multiple measures assessment for the lack of a community college perspective. The studies largely supported use of high …

Factors Predicting Family And Consumer Sciences Teachers' Levels Of Self-Efficacy In Stem Education, Charlene Wirfel Smith

STEMPS Theses & Dissertations

Education in science, technology, engineering, and mathematics (STEM) has become widely promoted in recent years. Quality STEM education could maintain or increase the number of individuals preparing for careers in these fields and increase STEM literacy for the population. Family and Consumer Sciences (FCS) education has always used science to improve home life while reinforcing technology, engineering, and mathematics principles through hands on, relevant learning activities in the classroom. However, it is not usually recognized as a STEM subject. The purpose of this study was to determine what factors may affect FCS teachers’ level of self-efficacy in teaching STEM education …

An Exploration Of Different Motivations Between Stakeholders And Visitors Of The Potomac Heritage National Scenic Trail, Colin Mccormack

Human Movement Sciences & Special Education Theses & Dissertations

Visitors have different motivations associated with parks and protected areas, and the people who run those areas are also different from visitors due to their unique positions. This is especially true for the Potomac Heritage National Scenic Trail (POHE), where stakeholders – ranging from park managers and Department of Transportation planners to volunteers of nonprofits and historical societies collaborate to manage sections along the 822-mile extent of the trail. Building on previous work itemizing the diversity of motivations for visitation to parks and protected areas, this study investigates similarities and differences in stakeholder and manager Recreation Experience Preferences by clustering …

A Nexus Of Literate Activity: The Design Of Writing Assignments In The Disciplines, Lauriellen Stankavich

English Theses & Dissertations

Writing plays a critical role in higher education as students are inducted into disciplinary practices through different genres, methodological repertoires and argumentation strategies. In Writing Across the Curriculum (WAC) initiatives, the instructor serves as an embodied reservoir of disciplinary knowledge and an arbiter of literate practices but most crucially employs the mediating capacities of the writing assignment as a potent pedagogical nexus. In this practice space, the instructor acts as designer of the pedagogical experience—the course as a whole and writing assignments in particular. This study used interviews, survey, and the collection of syllabi and other instructional artifacts to examine …

A Biomechanical Analysis Of Back Squats: Motion Capture, Electromyography, And Musculoskeletal Modeling, Eva Maria Urdiales Maddox

Human Movement Sciences & Special Education Theses & Dissertations

Previous literature evaluating maximal back squats have failed to identify key components of the study decisions and procedures that would allow for duplication. Firstly, the existence of a sticking region in maximally weighted resistance exercises is frequently discussed and has been described as a force-reduced transition phase between an acceleration phase and a strength phase of a lift. However, the etiology has yet to be agreed upon. Second, Electromyography (EMG) is frequently used to assess muscle activations. However, no best practice for EMG normalization has been proposed. Two methods are commonly implemented for normalizing EMG: a maximum voluntary isometric contraction …

Natural History Of Discourse Of Missouri House Bill 1042: Bringing A Critical Perspective To Policy Engagement In Two-Year Contexts, Mary Casey Reid

English Theses & Dissertations

In this autoethnographically-infused natural history of discourse (NHD) (Silverstein and Urban, 1996; Slembrouck, 2001), I use methods from critical discourse studies (CDS) to trace 10 years of changes in “remediation” discourses within a corpus of texts associated with Missouri HB 1042, a piece of legislation passed in 2012 that requires higher education institutions to “replicate best practices in remediation” (CBHE, 2013). After providing national and state context related to HB 1042 and the discourses circulating within the HB 1042 corpus of texts, I describe what I call the “higher ed’s remediation problem” discourse, focusing on three discourse features that I …

Investigating The Process Of Consequential Validity With The Ambassador Questionnaire, Melissa Gayle Kuhn

Educational Foundations & Leadership Theses & Dissertations

Validity in psychometrics refers to the degree to which evidence and theory supports the interpretations drawn from a test, and Messick’s Contemporary Validity Theory (1994) includes several facets with well-established evidence collection methods. However, there is a lack of consensus on appropriate methods of evaluating the facet of consequential validity, which is the degree to which interpretation of scores could have consequences for test-takers. The primary objective of this study was to illustrate a method of identifying potential consequences of survey in the stage of manual development. This method was placed in the context of the Ambassador Questionnaire (AQ) used …
