The Design And Development Of A Miniature Gridded Ecr Ion Thruster, Nicholas Nuzzo

Masters Theses

Plasma propulsion, a specific subset of electric propulsion (EP), is a class of space propulsion that produces plasma by excitation of a propellant at or above its ionization energy. This ionized propellant is then accelerated by an externally applied field (magnetic and/or electric) and produces thrust. There is an increasing need for miniaturization in spacecraft technology and the use of plasma EP devices in space propulsion. These systems provide an advantage over traditional chemical propulsion solutions which are less efficient and have more mass. Miniaturization of EP devices allows missions to have more space and mass available for their payloads …

Three Essays On Financial Economics, Megersa Daksa

Dissertations

This study presents three essays on financial economics. In the first essay, we examine how monetary policy shocks affect risk aversion and uncertainty, as well as how risk aversion and uncertainty spread across financial markets. Although a recent study shows that monetary policy influences risk aversion and uncertainty in global stock markets, there are no studies on risk aversion and uncertainty spillover across stock, currency, and commodity markets. Following the method of Bekaert et al. (2013), we decompose the implied volatility indexes (VIX's) for the SP500, U.S. exchange rate, gold and crude oil into risk aversion and uncertainty. The decomposition …

A Framework For Assessing The 4th Rank Dispersivity Tensor Under Anisotropic Axial Symmetries, Xiang Fan

Dissertations

Multi-dimensional expansion of the advection-dispersion equation necessitated the representation of dispersivity as a 4th rank tensor. This tensorial form of dispersivity has 81 terms in three-dimensions with a maximum of 36 independent terms that may be used to describe Fickian spreading of a dissolved contaminant plume according to intrinsic properties of a porous medium. The complexity of the 4th rank tensor has led to the common practice of simplifying the tensor to only 2 or 3 independent terms by assuming isotropic conditions, although isotropic porous media are uncommon in nature as many natural geologic systems exhibit pronounced anisotropy. A broad …

An Exploration Of Stressors And Perceptions Of Wellness Among Christian Church Ministry Wives, Laura Ann Kellicut

Dissertations

Ministerial families are in the unique situation of a two-person career, where although the husband is the only one employed by the church, the wife is also expected to perform church specific demands and responsibilities (Frame & Shehan, 1994; Lifeway, 2017). Unique variables and factors of stress among ministry wives have been identified along with how their role affects certain domains of life (Douglas, 1961; Frame & Shehan, 1994; Lee, 2007; Zoba, 1997; Luedtke & Sneed, 2018). Lifeway Research (2017) found that 78% of ministers' spouses experienced some level of burnout with 22% at the highest levels. In the literature, …

The Acculturation Process Of International Students In Cacrep Counseling Programs: A Grounded Theory Approach, Hanny Wuysang

Dissertations

International students bring diverse, multicultural perspectives to the U.S. postsecondary education system through their participation in higher education. However, in their adjustment to U.S. higher education, international students in counseling programs face barriers and challenges such as language differences, lack of support, microaggressions and discrimination, culture shock, and different perspectives on mental health treatment as compared to their home cultures. These factors can interfere with their daily personal and academic lives, yet there is often minimal support from their academic programs and host institutions. The growing number of international students in counseling programs increases the importance of understanding their acculturation …

Intersectional Identities Of Race And Religion Of African American Muslims And Their Attitudes Toward Seeking Mental Health Services, Cheruba A. Dhanaraj

Dissertations

African American Muslims have overlapping and interconnected identities of race and religion that can be conceptualized by the intersectionality framework to understand the complexities of barriers they face when seeking mental health services. African American Muslims have a higher risk of mental health issues due to systemic racism, racial discrimination, racial trauma, and Islamophobic discrimination. Yet, there is a lack of scholarly research or studies that focus explicitly on African American Muslims' specific mental health needs, barriers, and attitudes related to seeking mental health treatment.

This study sought to fill the gap in knowledge about attitudes toward seeking mental health …

Crafting A Different Kind Of Story: Experiences Of Creative Writers Leading In Higher Education, Meredith L. Dodson

Dissertations

Connections between creativity and leadership often focus on how fostering creativity can help an organization. Despite the value that creativity can bring to organizations, Mueller et al. (2011) found that creative people themselves are not seen as leadership material. Yet many people with creative backgrounds do take on leadership roles, particularly in higher education.

This qualitative study explores the experiences of higher education leaders who have a background in creative writing and how those leaders perceive the interaction of the leadership role with their creative experience. The sample included 12 mid-level leaders in higher education who had an MFA or …

Universal Pre-K In Comstock Public Schools, Meadow A. Nuyen

Dissertations

In 1971, President Nixon vetoed legislation that would have created federal funding for the education of kids under age five. With the veto, President Nixon reaffirmed that, except for poor children, the education and care of the children is the responsibility of the family, not the government. Yet over 31 years later, 41 states and the District of Columbia provide state-funded preschool (Waxman, 2021). Preschool in the state of Michigan is not automatically provided as K-12 education is. This study examined the beliefs of staff in Comstock Public Schools regarding Universal Pre-K, tuition-free preschool for all 4-year-olds. Participants included district …

Developing Distributed Real-Time Hybrid Simulation For Dynamic Response Evaluation Of Floating Wind Turbine, Hezha Lutfalla Sadraddin

Dissertations

Floating wind turbine (FWT) has a significant role in producing clean and sustainable energy in unlimited spaces with more steady wind and less cost. The design, construction, and safe operation of FWTs require a deep understanding of their dynamic responses under combined aerodynamic and hydrodynamic loads. Conventional FWT model experiments utilize wave tanks and wind tunnels. However, laboratory size and capacity and the scaling conflicts between the Froude and the Reynold numbers in these coupled wind-wave loading tests impose challenges to replicate dynamic responses of FWT. Alternatively, real-time hybrid simulation (RTHS), which combines numerical simulation and physical experiment of FWT …

Despite a slight increase in representation of female Black superintendents, minorities of all races continue to be underrepresented (Tienken & Domenech, 2020). In this study, I examined the experiences of Black superintendents in Michigan who currently hold superintendent roles, along with the obstacles they faced and their personal characteristics and associated factors that attributed to their resilience and longevity in their role as superintendent. Using a phenomenological qualitative study approach of personal and confidential interviews and survey questions of 12 Black superintendents, data was collected to formulate a toolkit for aspiring …

Preclinical Behavioral Assessments Of Mitraginyne, The Main Psychoactive Alkaloid In Kratom, Rachel Burroughs

Dissertations

Mitragyna speciosa (kratom) is a medicinal plant indigenous to Southeast Asia and Africa with a long history of use for a variety of ailments, including diarrhea, pain relief, cough suppression, and amelioration of opiate withdrawal symptoms. Despite its status as an herbal remedy, kratom is banned in some countries due to a myriad of negative health risks. Preclinical psychopharmacology studies of mitragynine (MG), the main alkaloid of kratom, indicate it has opioid-like effects at higher doses and psychostimulant-like effects at lower doses. The current study utilized three rodent behavioral paradigms to evaluate the putative psychostimulant effects of MG. The specific …

Instance Segmentation-Based Depth Completion Using Sensor Fusion And Adaptive Clustering For Autonomous Vehicle Perception, Mohammad Z. El-Yabroudi

Dissertations

Depth sensing is critical for safe and accurate maneuvering in robotics and self-driving car (SDC) applications. Most recent LiDAR sensors, such as Ouster and Velodyne, offer 360 degrees of scanning at the rate of ten frames per second, making them very appropriate for autonomous driving applications. However, LiDAR point cloud data show many shortcomings, especially its data sparsity and unassigned nature, making it very challenging to utilize in applications such as perception, 3D object detection, 3D scene reconstruction, and simultaneous localization and mapping.

In this study, a novel framework using instance image segmentation and the raw LiDAR data for the …

Heterogeneity Estimators In Random-Effects Meta-Analysis In Education, Qian Wang

Dissertations

Over the last four decades, meta-analysis has proven to be a vital analysis strategy in educational research for synthesizing research findings from different studies. When synthesizing studies in a meta-analysis, it is common to assume that the true underlying effect varies from study to study, as studies will differ in design, participants, interventions, or sample size that can lead to heterogeneity in their underlying effects. The magnitude of this heterogeneity between studies can be quantified as τ2 in a random-effects meta-analysis. Estimating the between-study heterogeneity (τ2) becomes an important part of random effects meta-analysis reporting, since this quantity plays a …
