The robotic platform consists of a 4-DoF dual-stage cartesian platform used to control the pose of a 1-DoF needle insertion module. The active …

Audience, Minah Kim

Graduate Theses and Dissertations

My work, “audience,” reflects binary oppressions sensed and recognized in my private memory and psychological space of living as a transnational being. Linguistic and sensical cognition I(a vulnerable transnational individual) had, have easily been dis-esteemed and devalued by White-centric epistemology. By confronting the reality of history that shapes my thoughts, performance, names, and meanings, I emphasize transnationality as an opportunity to multiply visual tools, dialogues, and inter-connections of individuals. This work integrates moments of physical connection and accountability by utilizing multidisciplinary expression, including ceramics, writing, sound, and the movements of performers and of the audience. Like an interfusion between artists …

Previous literature strongly supports a sex gap in risk perception, a pattern known as the White Male Effect (WME) …

News Media Trust And Mistrust During The Covid-19 Pandemic, Kaitlyn Seiter

Graduate Theses and Dissertations

With the uncertainty and growing information surrounding the COVID-19 pandemic, news media consumption has increased drastically compared to pre-pandemic consumption. At the start of the pandemic, 94% of Americans reported closely following COVID-19 news, with more than half of Americans spending more than two hours consuming COVID-19 news everyday (SSRS, 2020). With the news media serving as a critical source of information through this public health crisis, the public’s reactions, behaviors, and attitudes to the pandemic stem from the level of trust they have in the news media to share COVID-19 information. Because of this, this study examines trust in …

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 …

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), …

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

Graduate Theses and Dissertations

College campuses provide students with endless opportunities to become members of various student organizations that provide leadership, accountability, a sense of belonging, personal growth, and development. Many colleges have provided students with the opportunities to join social Greek fraternity and sorority organizations. The foundation of social fraternity and sorority organizations are built on principles such as sisterhood, brotherhood, scholarship, service, philanthropy, and leadership. Many traditional college-age women who desire to become members of a social sorority organization all participate in a formal recruitment process. There are various motivations that traditional college-age women have for joining social sororities on college campuses …

Advising Student Veterans In Higher Education, Brett Edward Rankin

Graduate Theses and Dissertations

Student veterans are a growing population in higher education with over 650,000 veterans using education benefits in 2018. Student veterans are enrolling in colleges of all types, and many institutions have support services designed for them specifically. In most cases these support services are limited to veteran centers where officials certify credit hours for financial benefits and do not offer services to help them fully assimilate into higher education. Student veterans bring a wide range of life experiences, culture, and work ethic to college campuses which serves to build and diversify the student body. However, veterans have reported feeling isolated …

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 …

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 …

The Impact Of Corporal Punishment For Timorese High School Graduates, Veronica Godinho Pereira

Graduate Theses and Dissertations

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 …

Queering The Metanarrative Of Domesticity: Chosen Families In Late Nineteenth- Century American Women's Literature, Sharla Rosenbaum

Graduate Theses and Dissertations

My primary purpose in this project is to dispel the notion that the white, bourgeois, patriarchal, nuclear family believed by millions of US citizens to have once monopolized the United States’s cultural landscape through an examination of how women authors in the United States constructed families in literature immediately following the Civil War. Not only do the novels under examination reflect diverse representations of families, but they also reflect those images from diverse perspectives. I will use a Marxist lens to explore class and ideologic interpellation; a renegade global feminist lens to explore failure and differential consciousness; a queer and …

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 …

[Dis]Assembling Race: The Fepc In Oklahoma, 1941-1946, Arley Ward

Graduate Theses and Dissertations

On the World War II home front in Oklahoma the Fair Employment Practice Committee (FEPC) succeeded in securing defense jobs for African Americans. The efforts of the committee, The Oklahoma Eagle, the Oklahoma City Black Dispatch, and the State Conference of Branches of the National Association for the Advancement of Colored People (NAACP) advanced civil rights in Oklahoma throughout World War II and beyond. The efforts of the FEPC in Oklahoma connect civil rights efforts in the 1940s directly to Brown v Board of Education, (1954) and the classic civil rights movement.

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 …

The analytic strategy included a single-case model of each family’s transcription, two-case model, cluster analysis to identify likeness, document portrait, and subtheme development. The structural descriptions that formed the essence of the experience resulted in three themes: education, migration, and emotional experiences. The three overall …

The Evolution Of Defeaters: A Taxonomy, Erica Nicolas

Graduate Theses and Dissertations

It has been widely argued that reasons for a belief come in degrees but not much literature has focused on the idea that defeaters for justification toward those beliefs also come in degrees. The aim of this paper is to explore epistemic defeasibility and construct a taxonomy for epistemic defeaters. This paper argues that epistemic defeaters undergo an evolutionary process before becoming what they are commonly labeled, such as rebutting and undercutting. I argue that within some stages of this process, there can be different degrees of defeat. This paper focuses on defeaters for justification, expands on the account of …

Symbolism Or Substance: Factors Influencing Campus Messaging Decisions And Their Alignment With Institutional Values, Laura Herzog Jacobs

Graduate Theses and Dissertations

Historically, institutions of higher education (IHE) have been cautious and slow in making changes. Yet in today’s fast-paced and dynamic world of content availability and information flow generated by 24-hour news cycles and the ubiquity of social media present a challenging reality for colleges and universities in their public relations and communications approaches (Sands & Smith, 2000). Creating a harmonious and agile approach to managing these responsibilities against the backdrop of an incessant flow and public demand for information, including responses to national events often with seemingly little or no connection to the institution, suggested a need to examine the …
