Mapping The Pathways To Campus Writing Sites: Implications For Writing Program Administrators, Meagon Clarkson-Guyll

Graduate Theses and Dissertations

This dissertation investigates the extent to which the writing program administrator and their affiliated writing program are structurally, organizationally, and rhetorically visibly connected to other campus sites of writing. To complete this project data was collected across five benchmarked institutions from publicly accessible online texts. Rhetorical analysis, informed by rhetorical genre studies and institutional ethnography, was conducted to conclude how writing programs are rhetorically situated in their home campus and how the role of the writing program administrator is rhetorically shaped within institutional structures and texts. The analysis concludes with recommended authorial interventions for the writing program administrator to adapt …

Body Mass And Body Condition Variation Of Mallards (Anas Platyrhynchos) Within And Among Winters Within The Lower Mississippi Alluvial Valley, John Thompson Veon

Graduate Theses and Dissertations

Most North American waterfowl overwinter in southern North America before migrating back to breeding grounds in the northern US and Canada. These species face the challenge of needing to maintain or increase their body mass during an environmentally difficult winter period. Successful body mass maintenance during the winter period has major ramifications not only for their winter survival but for their fitness across the entire year. Recent research in Europe and the western United States suggests that the body mass of mallards (Anas platyrhynchos) has increased from the late 1960s to early 2000s. However, the factors responsible for increases in …

Genome-Wide Analyses Of Genomic Variation Regulating Differential Stress Responses In Japanese Quail, Steven Anthony Shumaker

Graduate Theses and Dissertations

As consumer demands for poultry grow, producers work to improve bird productivity in both meat and egg production. This endeavor is multifaceted, as many different factors play a part in influencing the productivity of birds, including environmental conditions, overall health, and genetic potential. One aspect controlled for in all aspects of poultry production optimization is stress management. Mitigation of stress is of primary concern to producers, as improper stress management can have many deleterious effects on chickens. Stress management requires an understanding of poultry stress responses and their physiological mechanisms, which can be more deeply understood through genomic analysis. Chapter …

Does Self-Reference In Concept Mapping Influence Transfer?, Daniel A. Parker

Graduate Theses and Dissertations

Concept maps are a popular learning activity that have successfully demonstrated student learning outcomes. Research suggests that concept mapping has a positive effect on recognition, recall, and transfer. Likewise, researchers in cognitive psychology have shown the value of referencing oneself with a concept. Known as the self-reference effect, learners who connect their experiences or traits with new knowledge are more likely to remember that knowledge than if they used other mnemonic devices. Previous research suggests that integrating self-reference in concept mapping may improve recall. However, to date, no study has investigated the influence of this combination on higher order learning …

Should I Stay Or Should I Go? Compassion Organizing And The University Advancement Workplace, Christina Marie Smith

Graduate Theses and Dissertations

Compassion organizing has been described within positive organizational scholarship as an organization’s response to pain and suffering in organizational behavior and also the ability for organizations to flourish and promote joy and fulfillment in the workplace. Compassion organizing has been examined in organizational life through the four areas of noticing, feeling, acting, and sense-making. Previous research has focused on business and healthcare workplaces and has shown that compassion organizing is both an organizational and interpersonal social process. Because of the limited existing research on compassion organizing in the higher education workplace (and none with respect to the university advancement workplace), …

Two-Dimensional Black Phosphorus For Terahertz Emission And Near-Field Radiative Heat Transfer, Mahmudul Hasan Doha

Graduate Theses and Dissertations

The main focus of this work is to investigate two potential optical and optoelectronic applications of black phosphorus (BP): the near-field radiative heat transfer in plasmonic heterostructures with graphene and terahertz emission from multi-layer BP photoconductive antennas. When the separation distance between graphene-black phosphorene is much smaller than or comparable to the thermal wavelength at different temperatures, a near-field radiation heat transfer breaks the Planck blackbody limit. The magnitude of the near-field radiation enhancement acutely depends on the gate voltage, doping, and vacuum gap of the graphene and BP pair. The strong near-field radiation heat transfer enhancement of the specific …

How Bad Do You Want It?: The Personal Motivation Of Joining A Sorority, Garry Butler

Lgbtq+ College Students' Perceptions Of Social Presence And Self-Disclosure In Online Learning: A Single-Case Study, Scott Anthony Wright

Graduate Theses and Dissertations

Social interaction among learners plays a significant role in online learning environments (Garrison, 2006; Kreijns et al., 2014; Mykota, 2017). The construct of social presence in online courses is important because it influences interaction and connectedness among learners and its effects on their learning outcomes and emotional well-being. Social presence at its essence refers to how an individual is perceived as a "real person" in an online environment (Gunawardena & Zittle, 1997). Online students must decide what aspects of their social identities they share in their interactions with their peers and instructors. Furthermore, LGBTQ+ students must negotiate what aspects of …

Exploring How Counselor Educators Define, Assess, And Manage Student Disposition Throughout The Gatekeeping Process, Ryan Cowell

Graduate Theses and Dissertations

Professional disposition plays an important role in counselor-in-training (CIT) development. Disposition is defined as the attitudes, values, beliefs and behaviors that contribute to a becoming a professional (Spurgeon et al., 2012). In addition, disposition is an attribute that must be evaluated and remediated as a part of accreditation through the council for accreditation of counseling and related educational programs (CACREP). Despite, the importance of disposition in CIT development and the requirement from CACREP, there are several difficulties related disposition. First, there is not a universally accepted definition for disposition in counselor education. In addition, there are few psychometrically tested dispositions …

Automated Flight Controller Adaptive Compensation For Actuator Failures In Transport Type Aircraft, Daniel James Fresella

Graduate Theses and Dissertations

Aircraft operate over a wide range of conditions including atmospheric, weight, and center ofgravity changes. This presents a substantial challenge to automatic control system designers. When these operating conditions are merged with a partial or full control surface failure, automatic flight control is near impossible with conventional controllers. Additionally, when pilots experience control failure emergencies during flight, workload and fatigue increase drastically. The continued research of automatic flight control systems that can seamlessly adapt to unmodelled failures will enable a new generation of robust aircraft control. In this paper a 9th order 6 degree of freedom aircraft model is used …

Design, Extraction, And Optimization Tool Flows And Methodologies For Homogeneous And Heterogeneous Multi-Chip 2.5d Systems, Md Arafat Kabir

Graduate Theses and Dissertations

Chip and packaging industries are making significant progress in 2.5D design as a result of increasing popularity of their application. In advanced high-density 2.5D packages, package redistribution layers become similar to chip Back-End-of-Line routing layers, and the gap between them scales down with pin density improvement. Chiplet-package interactions become significant and severely affect system performance and reliability. Moreover, 2.5D integration offers opportunities to apply novel design techniques. The traditional die-by-die design approach neither carefully considers these interactions nor fully exploits the cross-boundary design opportunities.

This thesis presents chiplet-package cross-boundary design, extraction, analysis, and optimization tool flows and methodologies for high-density …

Sensitivity Of Soybean And Rice To Dicamba, Owen Wesley France

Graduate Theses and Dissertations

Although the integration of dicamba as a postemergence (POST) herbicide has proven useful in controlling many herbicide-resistant weeds, its damage to soybean at low rates, such as supplied by drift and volatility, has been well-documented. Injury to other crops, such as rice, from off-target movement of dicamba and other commonly used herbicides, such as glyphosate, may also occur. Practical options for mitigating injury and yield loss to soybean and other crops from dicamba off-target movement could prove beneficial if dicamba continues to be used during summer months. Experiments were conducted to determine the effects of multiple agricultural practices, including cultivar …

Fair And Diverse Group Formation Based On Multidimensional Features, Mohammed Saad A Alqahtani

Graduate Theses and Dissertations

The goal of group formation is to build a team to accomplish a specific task. Algorithms are being developed to improve the team's effectiveness so formed and the efficiency of the group selection process. However, there is concern that team formation algorithms could be biased against minorities due to the algorithms themselves or the data on which they are trained. Hence, it is essential to build fair team formation systems that incorporate demographic information into the process of building the group. Although there has been extensive work on modeling individuals’ expertise for expert recommendation and/or team formation, there has been …

Screening For Our Fathers: Representations Of Native American Masculinity In American Film, Jeromy Duane Miller

Graduate Theses and Dissertations

In this work, I examine representation of Native American masculinity in the American film industry. The American film industry began just over a century ago, and one of its earliest subjects was the Native American. Throughout its history, the American film industry has maintained a steady trajectory of exploitation and erasure of Native American men and their subsequent masculine qualities. While there are notable historical outliers and critical exceptions in the 21st century, Native American men in film have been continually reduced to corpses, devoid of significant social presence, and denied meaningful explorations of their sexuality and interpersonal identity. The …

Badnaam Women Of Bollywood: The Combative Sexual Politics Of Item Songs In India, Ketaki Deshpande

Graduate Theses and Dissertations

This study analyzes the controversial Bollywood convention “item number,” a vampy song with suggestive lyrics and hypersexualized imagery of dancing women, as a crucial cultural artefact reflecting the gender and sexual uneasiness in India. Sex avoidance is a common theme in Bollywood films and in the country, where media and people are heavily censored and policed by anti-Romeo squads under the Modi administration. The item girl breaks the sexual tension with a mega hit song and hook step that fuels the economy of dance and desire in India. While the song is completely unrelated to the narrative of the film, …

This research examines the impacts of corporal punishment for Timorese high school graduates. Physical punishment is a pervasive method of disciplining students and children used in Timor-Leste because it has been such a tradition (UNICEF 2017). Few researchers have attempted to analyze the negative impacts of corporal punishment and possible gender differences; there is no known research on the impacts of corporal punishment in Timor-Leste. This study uses an in-depth interview method, where data were collected from 26 Timorese high school graduates composed of both men and women from both private and public schools in Timor-Leste. The ages of the …

The Morphodynamic Interaction Of River Deltas And Their Marshes, Kelly M. Sanks

Graduate Theses and Dissertations

Globally, many of the largest river deltas contain vast marsh platforms that are currently threatened due to a combination of anthropogenic alterations to rivers and increasing relative sea level rise. Restoration and management plans for river deltas depend on optimizing riverine sediment accumulation in marsh platforms. However, the accumulation of organic material in marsh platforms is often neglected in predictive models and the interaction of ecogeomorphic processes governing marsh accumulation with the physical processes governing river delta growth is poorly understood.

Herein, I investigate this complex relationship through a combination of field and experimental studies. I show that in coastal …

Does Whispering Improve Children’S Memory? Comparing Auditory Vigilance And Salience Hypotheses, Christina M. Barnes

Graduate Theses and Dissertations

Oral communication is one of the primary tools children use to learn new information and speech registers can deliver additional meaning to the words someone uses. Cirillo’s (2004) vigilance hypothesis states “Whispering can affect the psychobiological state of recipients, and in particular raise their auditory vigilance” (Cirillo, 2004, p. 76). Building on this theory, the current study investigates the role of whispering and children’s memory by examining a whispering vigilance, whispering salience which focused on the changes between normal and whisper registers, and combined vigilance and salience hypotheses to determine if whispering contributes to the recall of information. Using video …

Hybrid Two Dimensional Quantum Devices, Joshua Patrick Thompson

Graduate Theses and Dissertations

This thesis describes measurements on hybrid material systems involving two dimensional (2D) materials and phenomena along with the development of a small, hermetically sealed cell. The hermetic cell is designed to assist with analyzing sensitive 2D materials outside of an inert environment. When working with van der Waals materials that are especially sensitive to oxygen or water, it can be difficult to identify usable thin flakes without exposing them to air. To help preserve materials for analysis in air, a capsule was designed that isolates the material in an inert environment. Although the capsule is hermetically sealed, the encapsulated material …

Diversifying Woolf’S Room: Private Spaces And Creativity In The Works Of Willa Cather, Kate Chopin, Gayl Jones, And Alice Walker, Ebtesam M. Alawfi

Graduate Theses and Dissertations

There is a divergence between Woolf’s vision of private physical spaces necessary for creating art and that of some feminists of color such as Alice Walker, Ortiz Cofer, and Gloria Anzaldua. Both Woolf and these contemporary scholars agree on the importance of physical spaces for female artists. However, they disagree on the nature of these spaces. Woolf’s private physical space is a room with a lock on the door whereas these writers’ room is the kitchen table, the bus, or the welfare line. Walker and like-minded writers challenge the narrowness of Woolf’s room because her locked room is a luxury …
