In this phenomenological qualitative study, the researcher observed and interviewed ten content-area middle school teachers to find out what happens in their classrooms with their low-proficiency readers. How did these teachers respond to their struggling readers in the classroom setting? Using data collected from questionnaires, teacher interviews, and teacher observations, the researcher captured the essence of …

Disability And Demographic Influences On Advanced Placement Calculus Performance: A Quantitative Analysis, Edward J. Storck

Theses and Dissertations

This quantitative study examined equity in Advanced Placement (AP) Calculus outcomes for students with Individualized Education Programs (IEPs) in New York State. Using statewide data from 16,457 AP Calculus AB and BC exam takers in 2023, the study investigated whether disability status, race/ethnicity, economic status, and English language proficiency predicted performance and the likelihood of passing. Findings revealed that disability status was not a statistically or practically significant predictor of AP Calculus outcomes; students with IEPs performed comparably to peers without IEPs once enrolled. No significant interaction effects were found between disability status and other demographic variables, suggesting that students …

Biogothic: New Directions In The Haunted Spaces Of Nineteenth Century Gothic Fiction, Jessica Mintzes

Theses and Dissertations

The BioGothic is a set of biological metaphors in nineteenth century Gothic fiction that anticipates our contemporary understanding of what we now think of as biological processes. The BioGothic system in the novel captures the site of connection and interaction between the body and the interior spaces it inhabits. The Gothic genre, from its inception, shifts the focus onto interior spaces and the ways in which architectural spaces and the Gothic body interact with one another. This demonstrates, in part, how physical space and biological matter are not only capable of becoming integrated with each other, but also maintain the …

The Effects Of Inadequate Training On Knowledge Management Systems: Retention Crisis Of Captains In The United States Army, Lexis R. Grudzinski

Theses and Dissertations

This research explores the relationship between the United States Army’s communication strategy in knowledge management for officers and the desires of captains to continue serving beyond their service obligation. Amidst the current retention crisis (Winkie, 2023) at the captain rank, blame often falls on factors outside of the Army’s control. This research, however, seeks to investigate a factor within the Army’s control and offer workable solutions.

For this research, we will use the common definition of knowledge management (KM): the process of creating, capturing, and organizing knowledge within an organization in a way that improves efficiency. KM includes both explicit …

Thinking Machines: Cybernetics, Artificial Intelligence, And Technological Anxiety In The American Cold War, Erin Mae Wilcox

Theses and Dissertations

Following the Second World War, cybernetics emerged as a cross-disciplinary study in philosophy, neurophysiology, electrical engineering, and mathematics. Cyberneticists proposed the formal study of the man-machine analogy; that is, to equate biological structures to a complex mechanical system. Drawing from this analogy, cyberneticists used programmable digital computers to emulate the functions of the human brain. The study of artificial intelligence emerged within this cybernetic discourse in the early 1950s; yet, by the mid-1960s, the two disciplines suffered a methodological fracture. Drawing from a tradition generated by this fracture, historians have traditionally examined cybernetics and artificial intelligence in isolation from one …

Fostering A Growth Mindset In Mathematics: Faculty And Student Experiences, Yolanda G. Rush

Theses and Dissertations

According to the Center for Community College Student Engagement (2019), many students attending two-year institutions need productive persistence strategies, including the development of a growth mindset. Although some growth mindset interventions have been effective in improving academic achievement among students (Boaler, 2016; Canning et al., 2024) and persistence (Lewis, 2019) among students, especially those with developmental needs (Suh et al., 2019) and those in mathematics, little is known about the experiences of students and teachers (i.e., students’ perceptions of teachers’ intentions and implementation) as teachers work to foster a growth mindset culture (Murphy et al., 2021). In this dissertation, I …

Examining Explicit Professional Development As A Means To Change Inclusive Mindsets, Mitchell E. Elatkin

Theses and Dissertations

Inclusive education requires educators to hold beliefs that support the participation and success of students with disabilities in general education settings. Although federal policy mandates access to the least restrictive environment, educator attitudes toward inclusion continue to influence the implementation of inclusive practices. The purpose of this mixed-methods study was to examine whether explicit professional development (PD) focused on inclusive mindsets influenced school stakeholders’ attitudes toward inclusion across a school year. Participants included representatives from various roles within a charter school organization in the Midwest. The researcher collected data through two administrations of the Adapted Teacher Attitudes Toward Inclusion Survey …

Social Media, Masculine Body Ideals, And The Drive For Muscularity: A Serial Mediation Model Across Sexual Identities, Sean P. Mcdaniel

Theses and Dissertations

Body image concerns among men are increasingly prevalent yet remain understudied compared to women’s experiences. Drawing on objectification theory, the present study examines the relationship between social media influence and men’s drive for muscularity through a serial mediation model. Specifically, the present study investigates whether the internalization of masculine body ideals and engagement in body surveillance behaviors mediate the link between social media influence and the drive for muscularity. Furthermore, the present study model attempts to explore how these processes differ across sexual identities, given evidence that sexual minority men face distinct sociocultural pressures regarding appearance. Adult male-identifying social media …

The Acculturation Of International-Born Student Affairs Administrators In The United States, Amber Joy Webb

Theses and Dissertations

This qualitative narrative study explored how international student affairs administrators in the United States experience acculturation. Guided by Berry’s (1997) fourfold model of acculturation, the study examined how participants experienced assimilation, integration, separation, and marginalization as they navigated their professional roles, institutional expectations, and cultural identities. Eight participants, representing diverse countries of origin, institutional types, and professional roles, were interviewed using a semi-structured interview guide. Data were analyzed using Braun and Clarke's (2006) framework. Findings indicated participants employed multiple, context-dependent acculturation strategies rather than adhering to a single strategy. Assimilation emerged as a strategic process for establishing professional legitimacy, navigating …

Understanding Workplace Psychological Safety Among Latina Professionals: An Exploration Of Intersectional Experiences, Michal Tapia

Theses and Dissertations

Latina professionals represent one of the fastest-growing segments of the U.S. workforce, yet they remain disproportionately underrepresented in executive and C-suite roles. This disparity reflects structural conditions that shape access to voice, support, advancement, and decision-making authority.

This mixed-methods study examined psychological safety among 145 Latina professionals across the United States, defined as the belief that one can speak up, ask for help, disagree, or raise concerns without fear of negative consequences (Edmondson, 1999, 2019). The study explored how identity, relationships, leadership, workplace support, inclusion, mentorship, and structural barriers shape psychological safety at work.

Quantitative analyses showed that workplace support …

Decline Of Male Enrollment In Higher Education, Oscar Valenzuela

Theses and Dissertations

The study examined the decline in male enrollment and completion in higher education, aiming to identify the reasons for the decline and to propose possible solutions. Using a qualitative phenomenological design, the study employed semi-structured interviews to collect data from males aged 18 to 40. The findings indicate that numerous factors contribute to why males are not enrolling in or completing higher education, and reveal key thematic groups, including Early Work Life, Home Life, Support Systems, Challenges, and Choices and Decisions. These results suggest that cultural background, socioeconomic status, and gender norms affect the decisions males make concerning higher education. …

Sibling Relationships Within The Context Of Chronic Conditions, Megan M. Sulak

Theses and Dissertations

This investigation explored how siblings and caregivers experience family life when one or more children have a chronic condition, with specific attention to examining what promotes connection, bonadaptation, and resilience among sibling pairs. Interviews with 10 members of 4 families contributed to the development of a grounded theory whose core theme centered on how knowledge often drove sibling relationship quality.  When individuals with chronic conditions, along with their siblings and parents, were able to access accurate knowledge and understanding about their condition, how to navigate fluctuations in health or illness, and the health care system, they reported being better able …

Comorbidity And Violence: What Role Does Resilience Play In Preventing Violent Acts?, Madeline J. Petit

Theses and Dissertations

The conjunction of substance use disorders, mental illnesses, and violence has been shaped through traditional risk-centered models, yet these approaches fail to explain why most individuals do not engage in violent behavior despite being high risk. This study aims to investigate how resilience may buffer the criminogenic effects of comorbidity and help understand the majority of those at risk who remain nonviolent. The data for this study is drawn from the MacArthur Violence Risk Assessment Study, which consisted of 2.255 person-waves, as the data examined comorbidity across 5 waves, consisting of 451 participants in each wave.Each participant in each wave …

Emotion Regulation Difficulties And Substance Use: The Role Of Conscientiousness, Caitlyn M. Donnelly

Theses and Dissertations

Difficulties in emotion regulation have been consistently linked to substance use among college students. However, individual differences may influence this relationship. Conscientiousness, a personality trait characterized by self-control, planning, and goal-directed behavior, has been proposed as a potential protective factor. The present study examined associations among difficulties in emotion regulation, conscientiousness, and substance use behaviors, as well as whether conscientiousness moderates the relationship between emotion regulation difficulties and substance use. Using a quantitative, cross-sectional, correlational design, data was collected from college students recruited through a university participant pool. Participants completed self-report measures of emotion regulation difficulties, conscientiousness, and substance use …

Leading The Temporary Workforce: Leadership Communication And Adaptation Among Seasonal Employees, Alfred Kwabena Obiri

Theses and Dissertations

Seasonal employees constitute an essential yet understudied workforce sustaining organizational operations during peak demand periods across industries. Despite the growing organizational reliance on temporary employees, organizational communication studies have primary focused on permanent employees with extended socialization periods, leaving important questions about how leadership communication operates in compressed timeframes inadequately addressed. This qualitative study examined how leadership communication practices shape seasonal employees’ adaptation, belonging, and morale within the temporal constraints characteristic of temporary employment. Drawing on organizational socialization theory, leader-member exchange theory and cultural dimensions, this study employed semi-structured interviews with 19 seasonal employees across hospitality, camp, retail, and education …

Elite Cues Vs. Economic Vulnerabilities: What Explains Isolationist Foreign Policy Attitudes Among Americans?, Sabyasachi Karmaker

Theses and Dissertations

This thesis examines whether contemporary isolationist foreign policy attitudes among Americans are better explained by elite political cues or by economic vulnerabilities. Using data from the 2024 American National Election Study (ANES), the study also examines which mechanism holds more explanatory power in shaping isolationist views. The findings show that both elite cues and economic vulnerabilities are associated with isolationist attitudes, but elite cues have greater explanatory power. These results suggest that contemporary American isolationism is more strongly associated with political identity and elite messaging than with economic hardship alone.

Built Different: Place, Identity, And The Holistic Well-Being Of Female Student Athletes, Jaye Mack

Theses and Dissertations

This research furthers the conversation surrounding holistic female student-athlete wellness, recognizing that their experiences can be inequitable – influenced by the intersectionality of race, gender, and athletic identity (Armstrong et al., 2018; Druckman et al., 2018; Neeley et al., 2021). This research accredits the physical environments where athletes train, recover, and connect as an underexplored factor in holistic well-being.

The Indivisible Self Model of Wellness (IS-WEL) was used to (1) explore the influence of physical design features on female student athletes' holistic well-being and (2) understand how their identity shapes how they experience and attach meaning to their team environments. …

From Deference To Dialogue: How International Gtas From High Power Distance Cultures Adapt To U.S. Classroom Dynamics, Deborah Akua Afi Appiah

Theses and Dissertations

International graduate teaching assistants (GTAs) from high power distance cultures play a significant role in undergraduate education at U.S. universities, yet they face challenges that go well beyond language proficiency. Coming from educational backgrounds where teacher authority is unquestioned and hierarchical, these GTAs must navigate American classrooms that operate on fundamentally different assumptions, where authority is earned rather than assumed, informality is the norm, and students expect to question, negotiate, and be personally known by their instructors. The present study examined how eighteen (18) international GTAs from seven (7) high power distance countries perceived and adapted to these differences while …

Secret-Keeping Experiences Of Young Adults, Jace C. Griffith

Theses and Dissertations

In 2020, researchers Frijns et al. called for a new wave of secret-keeping research which prioritized the person-centric experience of youth keeping secrets. This study added to that collection by comparing two kinds of secret-keeping which are not compared in existing research: secrets which are related to abuse, and secrets which are not. Researchers in the field of child welfare study only abuse-related secret-keeping, almost always qualitatively. Alternatively, researchers of non-abuse secret-keeping or general secret-keeping collect almost entirely quantitative data, absent of the personal experience of secret-keeping.

Through an online survey, 205 undergraduate students were asked to reflect on an …

Predicting Job Performance: The Incremental Validity Of Cognitive Reflection Tests Over General Cognitive Ability And Conscientiousness., Olivia Earll

Theses and Dissertations

Cognitive reflection is the ability to suppress intuitive thinking (Type 1) in favor of deliberative, analytical thought (Type 2). This study investigated cognitive reflection as a predictor of supervisor-rated job performance, exploring its incremental validity over general cognitive ability and conscientiousness. Results indicated that all three variables positively predicted job performance, with cognitive reflection explaining a significant, unique portion of the variance. Exploratory analyses confirmed that this predictive validity remained consistent across industry, age, and sex. Furthermore, cognitive reflection significantly moderated the relationship between general cognitive ability and job performance. These findings highlight the value of deliberative reasoning as a …

Between Tradition And Transition: Cultural Negotiations And Contraceptive Perceptions Among Ghanaian Students In The United States, Beatrice Amissah

Theses and Dissertations

As global mobility continues to rise, international students often encounter new cultural norms and health practices that differ from those in their home countries. While some studies have focused on contraception within the context of gender and types, less focus has been placed on diasporic populations, especially how students navigate tensions surrounding contraception within new cultural environments. This study explores how Ghanaian students in the United States interpret, negotiate, and respond to contraceptive messaging while navigating the cultural transition between their heritage and host societies. Drawing on Berry’s (1980)  Acculturation Theory, the study examines the tensions students experience, the strategies …
