Georgic Rhetoric, Virtue And The Commercialization Of Agriculture In Pennsylvania From 1785 To 1870, Naomi Ulmer

Masters Theses, 2010-2019

This research examines how farmers in Pennsylvania between 1785 and 1870 were persuaded by georgic agrarianism to take social, economic and even moral risks to abandon a semi-subsistence mode of production in favor of commercial production. The georgic rhetoric is derived from Virgil’s poem “The Georgics.” It discusses agriculture and man’s labor in nature. Virgil discusses the relationship between man, nature and his ability, or inability, to control nature to ensure his own survival. Beginning in the late 18^th century, supporters of improved agriculture, mostly wealthy and upper-class gentlemen, tried to persuade common yeomen farmers to produce for the …

Direct Observation Of Atomic Exchange During Surface Self-Diffusion, Matthew Aaron Koppa

Physics & Astronomy ETDs

The diffusion of adatoms across the (100) plane of iridium has been previously inferred to occur by an exchange mechanism based on site mapping. This study provides the first direct observation that surface self-diffusion can occur by exchange. Iridium enriched to ≥93% ¹⁹¹Ir was deposited onto an atomically clean and smooth Ir(100) plane as observed in an atom probe field ion microscope. Following thermally activated surface self-diffusion the adatom was field desorbed and mass analyzed. Observation of the ¹⁹³Ir isotope in one-half of the cases demonstrates conclusively that atomic exchange can occur during surface self-diffusion.

Learning Nearest Neighbor Graphs From Noisy Distance Samples, Blake Mason, Ardhendu S. Tripathy, Robert Nowak

Computer Science Faculty Research & Creative Works

We consider the problem of learning the nearest neighbor graph of a dataset of n items. The metric is unknown, but we can query an oracle to obtain a noisy estimate of the distance between any pair of items. This framework applies to problem domains where one wants to learn people's preferences from responses commonly modeled as noisy distance judgments. In this paper, we propose an active algorithm to find the graph with high probability and analyze its query complexity. In contrast to existing work that forces Euclidean structure, our method is valid for general metrics, assuming only symmetry and …

A Study To Determine Barriers That Impact Adult Learner Academic Success, Joann Saunders

CUP Ed.D. Dissertations

Adult learners often encounter obstacles that impede their academic progress and either withdraw from a course or drop out of college. There has been significant research conducted on effectively instructing and motivating adult learners. However, not enough research has been conducted to help adult learners sustain their motivation when barriers arise impacting their academic success. The goal of this study was to identify barriers that impact adult learners’ academic success. The study examined the viewpoints of undergraduate adult learners at an American higher education institution to determine situational, institutional and dispositional barriers encountered impacting their academic success. The research theoretical …

Effects Of A One-To-One Computer Environment On Student Academic Achievement, Amy M. Price

CUP Ed.D. Dissertations

A gap exists in current research due to a lack of studies that explore the effect of schoolwide one-to-one computer implementations on academic achievement. The purpose of this study was to determine the effect a one-to-one computing environment had on student academic achievement means of middle school students in rural Nevada. This quantitative, non-experimental study used a causal-comparative design and analysis of academic achievement archival data from the 2015–2016, the year before implementation; 2016–2017, the first year of one-to-one implementation; and 2017–2018, the second year of implementation. Two research questions guided this study: RQ1. Is there a significant difference in …

Long-Term Study Of Prescribed Fire Effects On Stand Dynamics And Oak Regeneration Potentials In Degraded Upland Oak-Hickory Stands In Northwestern Arkansas, Mason C. Danheim, Kathryn R. Kidd Dr, Hal O. Liechty Dr, Brian P. Oswald Dr

Electronic Theses and Dissertations

Upland oak-hickory forests in the Ozark Mountains of northwestern Arkansas and south central Missouri were impacted by oak decline during the early 2000s. This decline event was caused by predisposing (e.g., mature, dense stand conditions), inciting (i.e., drought), and contributing (e.g., red oak borer, E. rufulus H., outbreak) factors. Immediately following onset of the decline, substantial crown dieback and tree mortality, particularly for two red oak species (northern red oak, Quercus rubra Michx. and black oak, Q. velutina Lam.), were observed. In addition, densities of advanced oak regeneration were inadequate at this time, resulting in poor regeneration potentials for …

Maxgap Bandit: Adaptive Algorithms For Approximate Ranking, Sumeet Katariya, Ardhendu S. Tripathy, Robert Nowak

Computer Science Faculty Research & Creative Works

This paper studies the problem of adaptively sampling from K distributions (arms) in order to identify the largest gap between any two adjacent means. We call this the MaxGap-bandit problem. This problem arises naturally in approximate ranking, noisy sorting, outlier detection, and top-arm identification in bandits. The key novelty of the MaxGap bandit problem is that it aims to adaptively determine the natural partitioning of the distributions into a subset with larger means and a subset with smaller means, where the split is determined by the largest gap rather than a pre-specified rank or threshold. Estimating an arm's gap requires …

Explicit Self-Care For Principals And Their Teachers: A Qualitative Transcendental Phenomenological Study On Administrator Stress Levels, Nadia Oskolkoff

CUP Ed.D. Dissertations

Principals and their teachers experience stress levels to such a degree that student achievement can be negatively impacted. The purpose of this transcendental phenomenological qualitative study was threefold: to explore and better understand principals’ first-hand and lived experiences of on-the-job stress and their practices of self-care to negate that stress, understand if principals find it important to model the practice of self-care to their teachers to reduce stress levels, and understand principals’ awareness of their emotional intelligence and how they use that to support not only themselves but their staff. Three research questions were developed, and semistructured interviews were conducted …

How Teachers Perceive Students’ Socioeconomic Background And Academic Performance In Charter Schools, Brittany Strickland

CUP Ed.D. Dissertations

Teachers represent the frontline of education and many of them find themselves working daily with impoverished students. Teachers’ qualitative perceptions are useful for developing solutions to the problem of educating diverse students from lower socioeconomic backgrounds in charter schools. The purpose of this study was to understand teachers’ perceptions of a charter school environment and the association between low socioeconomic status (SES) students and their academic performance. A qualitative design and a case study methodology were used with two charter schools, including 45 participating teachers. Results from questionnaires and interviews ensured a sufficient understanding of the phenomenon. The collected information …

Giving Voice To African Immigrant Families: Perceptions Of African Immigrant Families About Their Children’S Experiences In U.S. Schools, J Hilary Gbotoe Jr.

CUP Ed.D. Dissertations

This qualitative ethnography case study examined perceptions of African immigrant families as it related to their children’s experiences in U.S. public schools. The primary research question that guided this study was, “What are African immigrant families’ perceptions of their children’s experiences in U.S. public schools?” This phenomenon was explored to uncover meanings African immigrant parents from Liberia attached to their children’s experiences in U.S. schools. The focus was on hearing stories the children told their parents about their experiences in U.S. public schools. Nonprobability sampling method was used to recruit participants. Eight families from Liberia, West Africa, were randomly selected …

Computer Self-Efficacy, Digital Learners, And Completion Rates In The California Community College System, John R. Otte

CUP Ed.D. Dissertations

The importance of online learning in higher education has increased considerably over the last two decades. As a result, online learning has become an important area of research. The purpose of the study was to examine if higher levels of computer self-efficacy (CSE) contributed to online course completion among online California community college students. Guided by Bandura’s (1977) work on self-efficacy and the work of Compeau and Higgins (1995) and Howard (2014) on computer self-efficacy, this study revealed that there is no relationship between high levels of CSE and successful completion of the course. A judgement sample was used to …

Supporting Children With Social And Emotional Challenges: A Phenomenological Study Of Teachers’ Experiences Using Social And Emotional Learning Competencies, Tina Pettway

CUP Ed.D. Dissertations

The purpose of this phenomenological study was to explore the lived experiences of teachers in supporting students who encounter social and emotional learning (SEL) challenges in the classroom. This study examined if and how SEL competencies were implemented by teachers in supporting students experiencing SEL challenges in the classroom. SEL was the framework used during this research. A total of 10 teachers from an urban school located in a southern state were selected to represent the population for this study. Data were collected via face-to-face individual semistructured interviews with all participants. Participants were asked to share personal artifacts of successful …

Tenacity, Angela Stevenson

Electronic Theses and Dissertations

ABSTRACT

Creating my exhibition, Tenacity, was a labor of love that took place over the year and a half that I was a student in Stephen F. Austin State University of Texas’s Graduate Program. I explored new processes in painting, including the use of transfers, and did extensive research into the lives of female historical figures. This exhibition was born of a wish to share knowledge with others as well as to remind society that anyone can elicit change.

Chronic Pain Acceptance: Optimism Mediates The Relation Between Dispositional Mindfulness And Pain Acceptance, Kelli Miles

Electronic Theses and Dissertations

ABSTRACT

Chronic pain is associated with many indicators of maladjustment. We expected that five individual components of dispositional mindfulness would be positively associated with pain willingness (Hypothesis 1) and activity engagement (Hypothesis 2). A mediational hypothesis was tested, whereby dispositional mindfulness would be positively associated with optimism and optimism would in turn be positively associated with both pain willingness and activity engagement (Hypothesis 3). Both Hypothesis 1 and 2 were partially supported. Acting with awareness and nonjudging were the only mindfulness components that were positively associated with pain willingness. Other components of mindfulness were either negatively associated with pain willingness …

Faculty Publications

© 2019 Author(s). The growth dynamics of gold-silver core-shell (Au@Ag) nanoparticles are studied using in situ time-dependent second harmonic generation (SHG) and extinction spectroscopy to investigate the nanoparticle shell formation. The silver shell is grown by reduction of silver cations onto a 14 nm gold core using ascorbic acid in colloidal aqueous solution under varying reaction concentrations producing Au@Ag nanoparticles of final sizes ranging from 51 to 78 nm in diameter. The in situ extinction spectra show a rapid increase in intensity on the timescale of 5-6 s with blue shifting and narrowing of the plasmonic peak during the silver …

A Pedagogic Analysis Of Linear Algebra Courses, Andrew Taylor

Mathematics & Statistics ETDs

This project is concerned with investigating the question, "Do our applied linear algebra courses (at the University of New Mexico) adequately prepare STEM students for future work in their respective fields?" In order to explore this, surveys were issued to three groups (sections) of students (among two different instructors) at the conclusion of their applied linear algebra course, as well as STEM professors/instructors from a variety of STEM fields. Students were surveyed regarding their perceived mastery of given topics/ideas from the course and professors/instructors were surveyed about the level of mastery they felt was necessary (referred to as ``desired mastery") …

Experiences Of Mainstream Students: A Qualitative Study, Raelyn Fuechtmann

Undergraduate University Honors Capstones

The experiences a student has in school influences the development of identity, self-worth, and perspective of the world into adulthood. There are numerous barriers to retaining clear access to information with ease in conventional educational settings such as public education; especially for those with hearing loss. Mainstream settings, where deaf and hard-of-hearing (D/HH) students are often the only one with hearing loss in the school, coupled with the journey of discovering their identity, can take a toll on D/HH students. This qualitative study observes and analyzes the formative experiences of D/HH students navigating their personal mainstream educational settings. Five interviews …

Authors Of Independence: Comparing Thomas Paine And Camilo Henríquez As Revolutionary Writers, Sean Gray

History & Classics Student Scholarship

An nineteenth-century Chilean writer, Fr. Camilo Henriquez was a fascinating figure—a Catholic priest whose religious beliefs more closely aligned with Deism, a prolific proponent of Chilean independence, and, for a short while, the president of the Chilean Senate. Because of his role in creating La Aurora, the first Chilean newspaper, Henríquez is often considered the “father of Chilean journalism” and the “mentor of the revolution." But to understand his role in the Chilean independence movement, we must juxtapose him with Thomas Paine, the pamphleteer extraordinaire of the American Revolution. The Enlightenment’s ideals of liberty and equality influenced both men, and, …

Homeland Insecurity, Amy Chen

Bachelor of Fine Arts Senior Papers

Homeland Insecurity is a project born out of a life’s worth of marginalization, internalized racism, and forced assimilation. It presents common experiences and emotions that are located between cultures, questioning what it means to inhabit a homeland that exists as a hybrid mental space. As I progress through life, my parents’ culture—my heritage—becomes more and more distant, yet like many non-white children of immigrants, I will continue to carry it in my face as a physical reminder of a life I do not know. Influenced by acculturation theory, my work explores this culture that never quite belonged to me to …

Ph-Sensitive Oxygen Release Microspheres To Enhance Cell Survival In Ischemic Condition, Zhongting Liu

McKelvey School of Engineering Graduate Student Theses & Dissertations

Ischemic diseases such as myocardial infarction, stroke and limb ischemia are severe cardiovascular diseases with high rate of death and millions of people suffered from these diseases. Under ischemic environment, cells die due to deficient supply of nutrient and oxygen. To regenerate ischemic tissues, stem cell therapy is a promising approach because stem cells can differentiate into cells necessary for the regeneration. However, stem cell therapy has limitations. For example, few cells can survive under harsh ischemic environment. To enhance stem cells survival, implantation of oxygen release microspheres to sustained supply cells with oxygen represents an effective strategy. Previously, our …
