Public Service Motivation And Volunteer Firefighters In Rural Environments, Terina Chapin Brooms

School of Public Service Theses & Dissertations

Volunteer firefighters serve their communities by offering life and property protection without compensation. With over 700 million volunteer firefighters in the United States, this population remains largely underrepresented in the public administration literature along with understanding public service motivation (PSM) in protective service industries. Using a sample of South Dakota volunteer firefighters, the study tested the applicability of PSM across a volunteer-based public service, the volunteer fire service. Through factor analysis, a viable PSM measure was confirmed across the sample consisting of the self-sacrifice and commitment to public interest dimensions. Compassion was notably unable to be confirmed as a dimension …

A Variable Shape Metastructure Based On Controlled Bistable Structural Elements, Mehmet R. Simsek

Mechanical & Aerospace Engineering Theses & Dissertations

The so-called hybrid position feedback controller is an unstable-then-stable position feedback controller, which is a second-order single-degree-of-freedom system in nature. This hybrid controller takes advantage of the resonant mode of a bistable system about one equilibrium position, destabilizes the system, and dynamically induces snap-through between the two equilibria. In this dissertation, a new multi degree of freedom metastructure concept that utilizes the hybrid position feedback controller is introduced. An arbitrary number of bistable “segments” or “structural elements” are attached to each other in a serial (or parallel) manner to generate a “distributed” bistable structure – also referred to as a …

Time Series Modeling To Ascertain Age In Fisheries Management, Kathleen Sue Kirch

OES Theses and Dissertations

The ability to assign accurate ages of fish is important to fisheries management. Accurate ageing allows for the most reliable age-based models to be used to support sustainability and maximize economic benefit. Structures used to age include bones, scales, and most commonly ear bones (otoliths). Assigning age relies on validating putative annual marks by evaluating accretional material laid down in patterns in fish otoliths, typically by marginal increment analysis. These patterns often take the shape of a sawtooth wave with an abrupt drop in accretion yearly to form an annual band and are typically validated qualitatively. Researchers have shown keen …

Climbing The Academic Ladder While Black: Exploring The Experiences Of Institutional Belongingness For Black Counselor Education And Supervision Doctoral Students At Predominantly White Institutions, Jasmine Alicia Hawa Griffith

Counseling & Human Services Theses & Dissertations

Although ample research investigates students’ belongingness experiences in counselor education (CE) programs, existing literature only marginally explores the realities of Black master students, and there is a notable lack of empirical attention to Black doctoral students’ belongingness experiences in counselor education and supervision (CES) programs. Investigating Black CES doctoral students' belongingness experiences at Predominantly White Institutions (PWIs) is critical to understanding how the Council for Accreditation of Counseling and Related Education Programs (CACREP) accredited CES programs can address the troubling statistic that Black doctoral students are least likely to become full-time CE faculty. Consequently, this study utilizes critical phenomenology from …

The Practices Of Instructional Design At Community Colleges: A Post-Qualitative Study Of The Mutual Invisibility Of Work, David Robert Niebuhr Tod

Educational Leadership & Workforce Development Theses & Dissertations

The work of instructional design in community college settings is woefully understudied. This study documents that work in three community colleges in the southeastern United States while placing it in the theoretical context of neoliberalism, and in line with that theoretical context, takes a post-structuralist stance in its methodological approach.

It is in the discourses of instructional quality, online teaching, and design that instructional designers and faculty engage with each other. In contrast to the more well understood working relationship in a four-year institution, the power relationships between these two groups have not been examined in a community college context. …

Examining The Role Of Access To Capital, Social Capital Networks, And Education In Supporting Black Founders And Investors In Technology-Based Entrepreneurship, Akosua Acheamponmaa

Engineering Management & Systems Engineering Theses & Dissertations

In recent years, a report from the Kauffman Index of Startup Activity shows that 540,000 Americans launch businesses each month (Fairlie et al., 2017). However, the number of women-owned and minority-owned businesses in the United States (U.S.) is disproportionately less than the proportion of women and minorities in the U.S. Although women slightly outnumber men in the U.S. (U.S. Census Bureau, 2019), new women-owned businesses represent only 39.4% of all U.S. businesses, while new male-owned businesses represent 60.51% (Fairlie et al., 2017). While Blacks or African Americans comprise approximately 13.4% of the U.S. population (U.S. Census Bureau, 2019), only 9.24% …

Appalachia In The Anthropocene: An Approach To Understanding Neo Appalachian Narratives As An Affective Ecology, Rachel Michel Bates

English Theses & Dissertations

Appalachia is all too often a commodified and mythologized place in the American consciousness. Yet the lived experience of Appalachia is one complicated by widescale ecological devastation, high poverty rates, and most recently, a devastating opioid crisis. Though much of Appalachian literature continues to dwell in an old vision of Appalachia, an endeavor Zackary Vernon terms post-Appalachian, I argue that a subset of texts published around the turn of the millennium, a time when many of the labor-dependent, exploitative industries such as logging, hydro damming, and coal mining were no longer at work in the region, reveal a shift in …

The Atmospheric Chemistry Experiment (ACE) satellite orbits Earth and records spectra through solar occultation limb observations. HOCl is a chlorine …

Inviting Submission: Isabella Beeton At The Englishwoman's Domestic Magazine, 1856-1865, Julie Megan Sorge Way

English Theses & Dissertations

Isabella Beeton, creator of the iconic domestic manual Beeton’s Book of Household Management, died suddenly in 1865, just before her twenty-ninth birthday. Her popular book survived to codify stereotypical Victorian female ideals. Yet the “Mrs Beeton” mythos camouflages a remarkable talent: far from domestic drudgery, Beeton maintained a vibrant career as a writer and editor at the Englishwoman’s Domestic Magazine (EDM), traveling widely to research the latest fashions and laboring behind the scenes to ensure the magazine’s success. Closely examining Beeton’s EDM work demonstrates how these formative, productive years shaped her later, more popular writing. Such a …

Study Of Deep Learning Models To Classify Nasa’S Kepler Light Curves, Heena Minnich

Computer Science Theses & Dissertations

The search for exoplanets has been an ongoing effort since the first discoveries of planets beyond our solar system in the 1990s. Finding a potentially habitable planet outside our solar system could provide key insights on life elsewhere in the universe. NASA Missions such as the Kepler, launched in 2009 and completed in 2018, have provided a massive amount of data in this goal by using the transit method to discover repetitive and periodic dips in visible light around a star. The transit method has been used to measure flux, the brightness of a star over time. These flux time …

Effects Of Balance Training On Spinal Reflexive Excitability Modulation, Corticospinal Excitability, And Balance Performance In Individuals With Chronic Ankle Instability, Sunghoon Chung

Rehabilitation Sciences Theses & Dissertations

Chronic ankle instability (CAI) is a neurophysiologic deficit resulting in diverse sensorimotor impairments. Following acute ankle sprains, pain, mechanical instability, and joint deafferentation reduce sensory input to the central nervous system (CNS). In response, the CNS sends altered motor signals to lower extremity muscles. These CNS changes contribute to various neuromuscular impairments in CAI patients, the most common of which is reduced balance performance. Specifically, CAI patients struggle to modulate spinal reflex excitability of the soleus muscle when progressing from simpler to more complex balance tasks. This overreliance on spinal reflexes results in inconsistent activation of the ankle stabilizing muscle. …

Innocence Through An Intersectional Lens: An Examination Of Women And Wrongful Convictions, Briana Paige

Sociology & Criminal Justice Theses & Dissertations

According to The National Registry of Exonerations (2022), nearly 40% of all exonerations involve a no-crime wrongful conviction. While women make up less than 10% of all exonerees, nearly 73% of exonerated women were originally convicted of crimes that never happened, compared to only 38% of exonerated men. Despite their prevalence, the topic of no crime wrongful convictions is extremely understudied in the wrongful conviction literature.

Additionally, since prior research on wrongful convictions has been primarily male centered, the likelihood that a woman’s case will be accepted to be reviewed for innocence is significantly lower than men (Free and Ruesink, …

Longitudinal Solid Polarized Target For Clas12 And Study Of Spin Structure Of Nucleons, Pushpa Pandey

Physics Theses & Dissertations

A suite of experiments measuring target-spin observables in electron-nucleon scattering (dubbed Run Group C) was conducted at Jefferson Lab’s Hall B in Newport News, VA with a new polarized nuclear target known as ‘APOLLO’ (Ammonia Polarized Longitudinally).

Normalized Ground State Of A Mixed Dispersion Nonlinear Schrodinger Equation With Combined Power-Type Nonlinearities, Zhouji Ma, Xiaojun Chang, Zhaosheng Feng

School of Mathematical & Statistical Sciences Faculty Publications

We study the existence of normalized ground state solutions to a mixed dispersion fourth-order nonlinear Schrodinger equation with combined power-type nonlinearities. By analyzing the subadditivity of the ground state energy with respect to the prescribed mass, we employ a constrained minimization method to establish the existence of ground state that corresponds to a local minimum of the associated functional. Under certain conditions, by studying the monotonicity of ground state energy as the mass varies, we apply the constrained minimization arguments on the Nehari-Pohozaev manifold to prove the existence of normalized ground state solutions.

Prevalence And Risk Factors Of Hikikomori In Young Adults In The Middle East, Harshil Paresh Shah

Theses

Hikikomori, a form of severe social withdrawal that can occur without the presence of any other psychological disorder, was once thought to be a Japanese culture-bound phenomena. However, studies have emerged from several parts of the world showing that this may be a global issue. Extant literature suggests associations between hikikomori and behavioral addictions such as gaming addiction and Problematic Social Media Use (PSMU). Since there is a relative paucity of research examining this phenomenon in the Middle Eastern context, this study aimed to determine the prevalence and risk factors of hikikomori in young adults of the Middle East. It …

Doubly Almost Bipartite Leonard Pairs, Shuichi Masuda

Dissertations and Theses

In Linear algebra, the concept of Leonard pair (LP) was motivated by the theory of Q-polynomial distance-regular graphs. In this dissertation, we will first give a brief introduction to LPs and to two closely-related classes of objects: (i) bipartite Leonard pairs (BLPs) and (ii) almost bipartite Leonard pairs (ABLPs). Taking these as departure points, we will introduce a new class of object - doubly almost bipartite Leonard pairs (DABLPs). The primary aim of our work is to fully classify (up to isomorphism) this new family. In addition, since there is known to be a natural correspondence between Leonard pairs …

Evaluation Of Modulus Of Elasticity Of Concrete Containing Both Natural And Recycled Concrete Aggregates, Zaiwei Li, Long Yuan Li, Shanshan Cheng

School of Engineering, Computing and Mathematics

There is growing requirement to use recycled aggregate in concrete to demote industrial wastes produced by construction sectors. Thus, to develop simple but meaningful formulations to assess the mechanical properties of concrete, when it is mixed with both natural and recycled aggregates, becomes essential. In the present study an analytical approach to calculate the elastic modulus of concrete containing both natural and recycled concrete aggregates is proposed. The approach is developed on the concept of effective medium approximation but considering the effect of Poisson's ratio. Two analytical formulas are derived. One is for the two-phase concrete (mortar and aggregate) that …

The botanical product commonly called "kratom" is still relatively novel to the United States. Like other natural products marketed as supplements, kratom is highly variable, both in terms of the alkaloids naturally occurring in kratom leaves and in terms of processing and formulation. Kratom products sold in the United States are not well-characterized, nor are daily use patterns among regular users. Surveys and case reports have comprised most of the literature on kratom use among humans. To advance our understanding of real-world kratom use, we developed a protocol for the remote study of regular kratom-using adults in the United States. …
