New Jersey Community Colleges: Is There A Relationship Between Part Time Faculty And Student Success?, Gerald Maxmilian Slusher

Theses and Dissertations

The increasing number of part time instructors in the community college professorate combined with low student retention and graduation rates makes research into part time faculty and student success highly germane. My dissertation investigated if higher ratios of adjunct faculty were related to student retention, certificate/degree attainment, and transfer without a credential while accounting for institutional, student body, and county characteristics. The dissertation was limited to New Jersey community colleges to eliminate differences in state policies. The sector was examined over 12 academic years yielding 228 data points arrayed into three panel models to run 12 regressions.

Transition From Clinician To Academician: A Heuristic Inquiry Of Role Change, Work-Role Conflict And Identity Development In Occupational Therapy, Theresa Rhett-Davis

Theses and Dissertations

Transitioning can be a daunting experience for occupational therapists shifting to an academic job as new faculty with new roles, responsibilities, and expectations. As newcomers to academia, occupational therapists can become overwhelmed by meeting the demands of the academic roles of teaching, scholarship, and service. Through a heuristic approach, I explored the lived experiences of occupational therapists who transitioned to academia from the clinical setting to better understand role change, work-role conflict, and academic identity development during the transition process. The person-environment-occupation-performance model provided a framework to understand the findings and give meaning to the OT faculty transition experience. The …

Ecuadorians In The Sacramento California Area: Attitudes And Language Maintenance, Jacob M. Strawn

Theses and Dissertations

The present qualitative study investigated Spanish language maintenance among a familial/friend group of ten Ecuadorians that live in Northern California. The participants completed a survey and participated in an interview from which I retrieved information about the importance of Spanish and English, their self-reported confidence in Spanish and English, language attitudes, language use in private/familial contexts, and language use in public/social contexts. Previous studies regarding language maintenance and language shift in California were primarily focused on the Mexican-American population. California has the fourth largest population of Ecuadorians in the United States, yet there are no maintenance and shift studies for …

A Large-Scale Survey Of Brown Dwarf Atmospheres, Savanah Kay Turner

Theses and Dissertations

Brown dwarfs are substellar objects that fall in-between the smallest stars and largest planets in size and temperature. Due to their relatively cool temperatures, the atmospheres of these 'failed stars' have been shown to exhibit interesting properties such as iron, silicate, and salt clouds. Theoretical atmospheric models based on known physics and chemistry can be used as tools to interpret and understand our observations of brown dwarfs. I have fit archival and new infrared spectra of over 300 brown dwarfs with atmospheric models. Using the parameters of the best-fit models as estimates for the physical properties of the brown dwarfs …

Rfssw Behavior Prediction Using A Numerical Model, Evan Robert Berger

Theses and Dissertations

A two-dimensional axisymmetric thermo-mechanical model of the Refill Friction Stir Spot Welding (RFSSW) process was developed and validated with experimental data. Welding temperatures, tool forces, and material flow including defect formation, were accurately predicted by the model. Qualified repair techniques are critical for successful implementation of a welding process for use on large weldments with a significant number of spot joints, and this work demonstrates a repair technique for RFSSW that is validated both experimentally and numerically. Repaired properties are shown to exceed 90% of the original mechanical properties of the RFSSW process. RFSSW has different process parameters for every …

The Rhetoric Of Teaching A Crisis: Incorporating Rhetorical Pedagogy Into Crisis Communications Textbooks, Maren Louise Johnson

Theses and Dissertations

A crisis is a pivotal moment for a company, and having prepared communicators can impact the reputation and financial state of a company. But there is currently a gap in learning how to manage a crisis and performing in the workplace. To explore this problem, I analyzed the four most popular textbooks in crisis communications and analyzed how they used theory to help students craft a fitting response to a crisis. My thesis recommends incorporating rhetorical theory, specifically the theory of the rhetorical situation, to bridge theory and practice and provide students with flexible theory to learn how to respond …

Disentangling Sexual Selection On A Complex, Multicomponent Trait: Song Of The Northern House Wren, Rachael A. Disciullo

Theses and Dissertations

Beautiful and abundant, bird song has long captured the attention of evolutionary biologists interested in sexual selection. Although most studies have examined single facets of song in relation to male-male competition (intrasexual selection) and female mate choice (intersexual selection), selection typically acts on multiple components that collectively influence an individual’s mating success. By studying how multiple components of song simultaneously play a role in male-male competition and female mate choice, we can better understand how sexual selection has directly and indirectly shaped this elaborate trait. I explored the role of male song in the context of sexual selection in northern …

Comparative Gpr Analysis Of Carbonate Strandline Deposits, Sydney Adelaide Richards

Theses and Dissertations

The Bahamas Island archipelago grows by the precipitation and secretion of calcium carbonate. A majority of this growth is by lateral accretion of shoreline sedimentary deposits. Previous research is not clear on whether the growth is largely due to eustasy, sediment input from catastrophic events, or a combination of both. The Bahamas is an ideal location for studying Holocene carbonate generation and deposition, but there is limited research on the analysis of strandlines in relation to lateral accretion. Carbonate strandline deposits are commonly classified as low-energy beach ridge deposits. Previous researchers have primarily focused on ooid shoals and subtidal regions. …

Bézout Domains And Elementary Divisor Domains: Are They The Same?, Michael D. Walton

Theses and Dissertations

This thesis examines the connections between Bézout domains and elementary divisor domains. I establish what both of these domains are, and I provide some clarifying examples of each. I state and prove some key results that have been established already in the literature. I describe a process by which I tried to show a distinction between Bézout domains and elementary divisor domains, and then provide an explicit example which shows that this process as formulated would not lead to an example of a Bézout domain which is not an elementary divisor domain. Throughout the thesis, I also state open questions …

The Impact Of Independence: A Look At First-Generation College Student Writers' Help-Seeking Behaviors, Emily Durney

Theses and Dissertations

In this qualitative research study, I share first-generation college students' help-seeking experiences with writing tasks and use an affective lens to investigate how first-generation students feel when navigating various help-seeking situations. Often, students' experiences and emotions highlight their commitments to independence. In this study, I found that students' feelings of insecurity and confidence both encouraged and discouraged help seeking with writing, that students expressed determination as a central affect when describing their commitment to independence, and that loneliness is a significant affect in regards to writing help seeking and independence. These findings provide writing center faculty and tutors and first-year …

Descriptions, Ecological Associations And Predictive Species Distribution Models Of New Species Of Psilochalcis Kieffer (Hymenoptera; Chalcididae) Occurring In Utah's Eastern Great Basin, Mark J. Petersen

Theses and Dissertations

The genus Psilochalcis, of the Family Chalcididae, was originally described in 1905 by Kieffer. Mainly considered an Old-World taxon, the first North American Psilochalcis were not identified until 1981 by Grissell and Schauff. Little is known about the species distributions, biologies and ecological relationships of these parasitic wasps. This dissertation describes research conducted in central Utah setting arrays of Malaise traps in 4 different habitat types common to the Great Basin at three separate locations. A result of this sampling revealed a high abundance of multiple species of Psilochalcis wasps, particularly from one location and two habitat types. Chapter 1 …

Use And Misuse Of X-Ray Photoelectron Spectroscopy (Xps): Reproducibility, Gross Errors, Data Reporting, And Peak Fitting, George Hobbs Major

Theses and Dissertations

X-ray photoelectron spectroscopy (XPS) is the most widely used surface analysis technique for chemically probing surfaces. Its popularity stems from the large amount of information that can be gathered about the electronic states of the atoms it probes, including core shell information and valence electron information. Simple qualitative analysis (peak identification) can often be performed, but quantitative analysis is a much more complicated process. Although XPS usage has increased dramatically, so has the amount of erroneous analysis observed in the literature. In my thesis, I first present a perspective on how to improve the quality of surface and material data …

A Survey Of Graph Neural Networks On Synthetic Data, Brigham Stone Carson

Theses and Dissertations

We relate properties of attributed random graph models to the performance of GNN architectures. We identify regimes where GNNs outperform feedforward neural networks and non-attributed graph clustering methods. We compare GNN performance on our synthetic benchmark to performance on popular real-world datasets. We analyze the theoretical foundations for weak recovery in GNNs for popular one- and two-layer architectures. We obtain an explicit formula for the performance of a 1-layer GNN, and we obtain useful insights on how to proceed in the 2-layer case. Finally, we improve the bound for a notable result on the GNN size generalization problem by 1.

Progressive Education In C. S. Lewis's Prince Caspian, Voyage Of The Dawn Treader, And The Silver Chair: Narnia As A Remedy To The Green Book, Megan Marie Johnson

Theses and Dissertations

Recent scholarship has taken an interest in C. S. Lewis's political views and how they are manifested in his fiction. However, few have thoroughly analyzed the specific political implications of his children's series, The Chronicles of Narnia. Part of this may be because Lewis himself insisted his fiction was nonpartisan. The heavily religious allegories in the series can also overshadow the political commentary. This thesis contributes to the growing discourse on political commentary in Lewis's fiction by identifying four concerns he had with progressive education and then demonstrating how he criticizes them in Prince Caspian, The Voyage of the Dawn …

Having life insurance is critical for hundreds of millions of people around the world as a key part of sound financial protection for individuals and families, but there are unacceptably high populations that lack coverage. 106 million Americans are uninsured or underinsured, the protection gap being pronounced in communities of color. Making the rigorous process of purchasing insurance easier is crucial in helping protect the financial security of millions. Automated and accelerated underwriting, a relatively nascent practice in the mature life insurance industry, is intended to streamline this process and narrow this coverage gap by making it easier to obtain …

Language Ideology In The Actfl Speaking Proficiency Guidelines, Sonja A. Mecham

Theses and Dissertations

This paper examines language ideology in the ACTFL (American Council on the Teaching of Foreign Languages) 2012 speaking proficiency guidelines using the method of critical rhetoric analysis. Language ideologies, a concept borrowed from linguistic anthropology, are the ways people and organizations conceptualize and talk about language. In this paper, I explore how the ACTFL speaking proficiency guidelines discuss proficient language. Since these guidelines are widely used and highly respected, it is necessary for those who use them to understand what ideologies of proficiency they express. Therefore, this study also discusses how the language ideologies in the guidelines may impact consequential …

Open Educational Resources And Equity: Lived Experiences Of Minoritized Educators, Jacob Rogers

Theses and Dissertations

Open educational resources (OER) have been heralded for their ability to provide educational equality amongst learners worldwide. While this possibility offers to transform the availability of educational materials with only very specific limitations (devices, bandwidth, and ability to engage), it is seriously noted that the production of OER is typically sourced from the same homogenous sources as traditionally published texts (e.g., white males at elite universities in the U.S.). Additionally, while there are emboldened strides towards equality (equal access to materials), there remains an educational gap providing educational equity (equal opportunity to succeed) in the design as well as the …

Afrikaans Taboo Words: Offensiveness Ranking And Reflections In Usage, Rebecca Brenkman

Theses and Dissertations

This thesis analyzes the offensiveness of Afrikaans taboo words gathered from an online survey and cross-compares it to grammatical constructions and functionality as displayed in an Afrikaans corpus. Culturally speaking, Afrikaans has a rich history of taboo terminology, especially in the racial category. The historical importance of taboo terms aids in understanding the evolution of the offensiveness of terms, especially as influenced by factors such as politics, attitude shifts, younger generations, etc. Results from the online survey focused primarily on the White Afrikaans-speaking population, as minimal responses were gathered from other ethnic groups. Additional findings from the survey indicated that …

Prevalence And Predictors Of Intern-Related Burnout In Dietetics Preceptors, Holly Hopkins

Quantifying the prevalence of burnout and identifying the predictors of burnout can help key stakeholders identify and implement strategies that prevent or mitigate burnout in dietetics preceptors. The purpose of this study was to determine the prevalence of intern-related burnout in dietetics preceptors and to identify the predictors of this burnout. This study used a cross-sectional study design. A survey instrument that included burnout and precepting measures, and items about the respondents’ personal and work characteristics was distributed to a random sample of 10,000 dietetics …

Load-Deformation Behavior Of Tension-Only X-Brace Roof Truss Diaphragms, Benjamin Johnson Meek

Theses and Dissertations

The alternative seismic design provisions for diaphragms provided in ASCE 7-22 Minimum design loads and associated criteria for buildings and other structures Section 12.10.3 account for both diaphragm ductility and displacement capacity, producing more accurate design forces and decreased detailing when compared to conventional seismic design methods. However, the diaphragm design force reduction factor has not yet been determined for tension-only roof truss diaphragms, a common system used in metal buildings. In this study, experimental tests of two cantilevered diaphragm subassembly specimens with tension-only rod bracing were conducted to determine the load-deformation behavior of the system. The first specimen used …

Forest Understory Plant Community Response To Prescribed Fire And Mechanical Thinning Treatments, Noelle V. Zenger

Theses and Dissertations

Much of the biodiversity in a forest comes from the understory vegetation. However, centuries of fire suppression in the western United States have made human-implemented disturbance necessary for reinstating natural disturbance cycles. However, the mechanical thinning and prescribed burning treatments used by land managers may differentially affect the response of the understory community. This study aimed to compare how prescribed fire and mechanical thinning treatments, with the size and severity of those treatments, affect understory plant communities in aspen-conifer forests over time. We sampled the understory community in burned, mechanically thinned, and untreated forest stands one, three, or five years …
